  1. "Sydney sandstone": Heritage Stone from Australia (United States)

    Cooper, Barry; Kramar, Sabina


    Sydney is Australia's oldest city being founded in 1788. The city was fortunate to be established on an extensive and a relatively undeformed layer of lithified quartz sandstone of Triassic age that has proved to be an ideal building stone. The stone has been long identified by geologists as the Hawkesbury Sandstone. On the other hand the term "Sydney sandstone" has also been widely used over a long period, even to the extent of being utilised as the title of published books, so its formal designation as a heritage stone will immediately formalise this term. The oldest international usage is believed to be its use in the construction of the Stone Store at Kerikeri, New Zealand (1832-1836). In the late 19th century, public buildings such as hospitals, court houses as well as the prominent Sydney Town Hall, Sydney General Post Office, Art Gallery of New South Wales, State Library of New South Wales as well as numerous schools, churches, office building buildings, University, hotels, houses, retaining walls were all constructed using Sydney sandstone. Innumerable sculptures utilising the gold-coloured stone also embellished the city ranging from decorative friezes and capitals on building to significant monuments. Also in the late 19th and early 20th century, Sydney sandstone was used for major construction in most other major Australian cities especially Melbourne, Adelaide and Brisbane to the extent that complaints were expressed that suitable local stone materials were being neglected. Quarrying of Sydney sandstone continues today. In 2000 it was recorded noted that there were 33 significant operating Sydney sandstone quarries including aggregate and dimension stone operations. In addition sandstone continues to be sourced today from construction sites across the city area. Today major dimension stone producers (eg Gosford Quarries) sell Sydney sandstone not only into the Sydney market but also on national and international markets as cladding and paving products

  2. Retrofitting Housing with Lightweight Green Roof Technology in Sydney, Australia, and Rio de Janeiro, Brazil

    Directory of Open Access Journals (Sweden)

    Full Text Available The built environment contributes around half of total greenhouse gas emissions and with 87% of residential buildings that we will have by 2050 already built, it is vital to adopt sustainable retrofitting practices. The question is: what are the viable solutions? One answer may be green roof retrofitting. The environmental benefits include reduced operational carbon emissions, reduced urban heat island effect, increased bio-diversity, housing temperature attenuation and reduced stormwater run-off. The economic benefits are the reduced maintenance costs and lower running costs. The social gain is the creation of spaces where people have access to green areas. However, the barriers to retrofitting include the perceptions of structural adequacy, the risk of water damage, high installation and maintenance costs, as well as access and security issues. Many Australian and Brazilian residential buildings have metal sheet roofs, a lightweight material with poor thermal performance. During the summer, temperatures in Sydney and Rio de Janeiro reach 45 degrees Celsius, and in both cities, rainfall patterns are changing, with more intense downpours. Furthermore, many residential buildings are leased, and currently, tenants are restricted by the modifications that they can perform to reduce running costs and carbon emissions. This research reports on an experiment on two small-scale metal roofs in Sydney and Rio de Janeiro to assess the thermal performance of portable small-scale modules. The findings are that considerable variation in temperature was found in both countries, indicating that green roof retrofitting could lower the cooling energy demand considerably.

    Arjunan, Punitha; Poder, Natasha; Welsh, Kerry; Bellear, LaVerne; Heathcote, Jeremy; Wright, Darryl; Millen, Elizabeth; Spinks, Mark; Williams, Mandy; Wen, Li Ming


    Issue addressed Tobacco consumption contributes to health disparities among Aboriginal Australians who experience a greater burden of smoking-related death and diseases. This paper reports findings from a baseline survey on factors associated with smoking, cessation behaviours and attitudes towards smoke-free homes among the Aboriginal population in inner and south-western Sydney. Methods A baseline survey was conducted in inner and south-western Sydney from October 2010 to July 2011. The survey applied both interviewer-administered and self-administered data collection methods. Multiple logistic regression was performed to determine the factors associated with smoking. Results Six hundred and sixty-three participants completed the survey. The majority were female (67.5%), below the age of 50 (66.6%) and more than half were employed (54.7%). Almost half were current smokers (48.4%) with the majority intending to quit in the next 6 months (79.0%) and living in a smoke-free home (70.4%). Those aged 30-39 years (AOR 3.28; 95% CI: 2.06-5.23) and the unemployed (AOR 1.67; 95% CI: 1.11-2.51) had higher odds for current smoking. Participants who had a more positive attitude towards smoke-free homes were less likely to smoke (AOR 0.79; 95% CI: 0.74-.85). Conclusions A high proportion of participants were current smokers among whom intention to quit was high. Age, work status and attitudes towards smoke-free home were factors associated with smoking. So what? The findings address the scarcity of local evidence crucial for promoting cessation among Aboriginal tobacco smokers. Targeted promotions for socio-demographic subgroups and of attitudes towards smoke-free homes could be meaningful strategies for future smoking-cessation initiatives.

  5. The health benefits of reducing air pollution in Sydney, Australia. (United States)

    Broome, Richard A; Fann, Neal; Cristina, Tina J Navin; Fulcher, Charles; Duc, Hiep; Morgan, Geoffrey G


    Among industrialised countries, fine particle (PM2.5) and ozone levels in the Sydney metropolitan area of Australia are relatively low. Annual mean PM2.5 levels have historically remained below 8 μg/m(3) while warm season (November-March) ozone levels occasionally exceed the Australian guideline value of 0.10 ppm (daily 1 h max). Yet, these levels are still below those seen in the United States and Europe. This analysis focuses on two related questions: (1) what is the public health burden associated with air pollution in Sydney; and (2) to what extent would reducing air pollution reduce the number of hospital admissions, premature deaths and number of years of life lost (YLL)? We addressed these questions by applying a damage function approach to Sydney population, health, PM2.5 and ozone data for 2007 within the BenMAP-CE software tool to estimate health impacts and economic benefits. We found that 430 premature deaths (90% CI: 310-540) and 5800 YLL (95% CI: 3900-7600) are attributable to 2007 levels of PM2.5 (about 2% of total deaths and 1.8% of YLL in 2007). We also estimate about 630 (95% CI: 410-840) respiratory and cardiovascular hospital admissions attributable to 2007 PM2.5 and ozone exposures. Reducing air pollution levels by even a small amount will yield a range of health benefits. Reducing 2007 PM2.5 exposure in Sydney by 10% would, over 10 years, result in about 650 (95% CI: 430-850) fewer premature deaths, a gain of 3500 (95% CI: 2300-4600) life-years and about 700 (95% CI: 450-930) fewer respiratory and cardiovascular hospital visits. These results suggest that substantial health benefits are attainable in Sydney with even modest reductions in air pollution.

  9. Hematuria at laparoscopic hysterectomy: a 9-year review at Sydney West Advanced Pelvic Surgery, Australia. (United States)

    Wilson, Matthew; Merkur, Harry


    The aim of this study was to estimate the prevalence and significance of hematuria during laparoscopic hysterectomy for benign uterine disease. The review assessed its incidence, risk factors, site of associated urinary tract injuries, methods of diagnosis, management strategies, and most likely intraoperative point at which hematuria occurred during laparoscopic hysterectomies. A retrospective review of 755 cases of laparoscopic-assisted and total laparoscopic hysterectomies from January 1998 through December 2006 was undertaken at Sydney West Advanced Pelvic Surgery, Sydney, Australia.

  10. The recovery of oyster (Saccostrea glomerata) populations in Sydney estuary (Australia). (United States)

    Birch, G F; Scammell, M S; Besley, C H


    The current work documented a significant and widespread increase in the abundance of the Sydney rock oyster Saccostrea glomerata, in Sydney estuary (Australia) by undertaking surveys of oyster density in the estuary in 1989 and annually from 1994 to 2006. Oyster density at six control sites located in nearby National Parks unaffected by boating and stormwater discharges were compared to 17 study sites widely distributed within Sydney estuary. No oyster populations were evident in Sydney estuary in 1989; however, by 1994 oysters had colonised areas of the lower and central estuary and by 2002 densities were statistically similar to control sites. The timing of estuary-wide increases in oyster abundance suggests that the partial banning of tributyltin in 1989 for vessels under 25 m long may have played a major role in the increase of S. glomerata in this estuary.

  11. The advent of psychosurgery in Australia-with particular attention to its introduction into Sydney. (United States)

    White, Richard T; McGee-Collett, Martin


    The objective of this study was to describe the advent of prefrontal lobotomy in Sydney and, less comprehensively, its introduction into Australia. Reference to journal articles, books, reports and archival data held at the Royal Prince Alfred Hospital and via internet searches, interviews and personal memory. This paper describes the arrival of psychosurgery in Sydney in the mid-1940s, and less comprehensively, its arrival in other Australian cities. In New South Wales, from 1945 or 1946, prefrontal lobotomies were conducted in private clinics and in public hospitals but, because of legal and practical hurdles, it is unlikely that psychosurgery was performed in mental hospitals prior to December 1958. This paper gives some details regarding the participation of neurosurgeons and of the major public hospitals in psychosurgery, and touches on the attitudes within the Australian medical profession towards this dramatic new therapy. © The Royal Australian and New Zealand College of Psychiatrists 2016.

  12. Historic change in catchment land use and metal loading to Sydney estuary, Australia (1788-2010). (United States)

    Birch, G F; Lean, J; Gunns, T


    Sydney estuary has a long history of environmental degradation and is one of the most modified water ways in Australia due to a highly urbanised catchment (~77 %) and a high population (4.6 million). The objectives of the present study were to map historical land use change from European settlement (1788) to 2010 to determine catchment evolutionary pathways and to estimate catchment loading (total suspended solids, Cu, Pb and Zn) to the estuary over this period. Land use distribution in Sydney catchment, determined for seven time horizons over this period, indicated that a substantial increase in residential land use through subdivision of large estates and an increase in road area resulted in a marked increase in metal loading to Sydney estuary between 1892 and 1936. The decline in industrial activity from a maximum in 1978 (3.9 %) to 1.8 % in 2010 and the introduction of unleaded fuel during this time was accompanied by reduction in metal loading to the estuary. Land use time horizon maps enabled the creation of novel, ternary diagrams to represent temporal evolution in catchment land use. The 15 sub-catchments of Sydney estuary were combined into three major catchment categories, i.e., urban, dense urban and commercial. Present-day annual discharge of stormwater from the Sydney catchment was calculated to be 466,000 ML and annual loadings of total suspended sediment (TSS), Cu, Pb and Zn in tonnes were 49,239, 27, 37 and 57, respectively. Stormwater has superseded industry as the main source of anthropogenic metals to this estuary in recent times.

  13. Retrospective Analysis of Patient Presentations at the Sydney (Australia) Royal Easter Show from 2012 to 2014. (United States)

    Crabtree, Nathan; Mo, Shirley; Ong, Leon; Jegathees, Thuvarahan; Wei, Daniel; Fahey, David; Liu, Jia Jenny


    Introduction Comprehensive studies on the relationship between patient demographics and subsequent treatment and disposition at a single mass-gathering event are lacking. The Sydney Royal Easter Show (SRES; Sydney Olympic Park, New South Wales, Australia) is an annual, 14-day, agricultural mass-gathering event occurring around the Easter weekend, attracting more than 800,000 patrons per year. In this study, patient records from the SRES were analyzed to examine relationships between weather, crowd size, day of week, and demographics on treatment and disposition. This information would help to predict factors affecting patient treatment and disposition to guide ongoing training of first responders and to evaluate the appropriateness of staffing skills mix at future events. Hypothesis Patient demographics, environmental factors, and attendance would influence the nature and severity of presentations at the SRES, which would influence staffing requirements. A retrospective analysis of 4,141 patient record forms was performed for patients who presented to St John Ambulance (Australian Capital Territory, Australia) at the SRES between 2012 and 2014 inclusive. Presentation type was classified using a previously published minimum data set. Data on weather and crowd size were obtained from the Australian Bureau of Meteorology (Melbourne, Victoria, Australia) and the SRES, respectively. Statistical analyses were performed using SPSS v22 (IBM; Armonk, New York USA). Between 2012 to 2014, over 2.5 million people attended the SRES with 4,141 patients treated onsite. As expected, the majority of presentations were injuries (49%) and illnesses (46%). Although patient demographics and presentation types did not change over time, the duration of treatment increased. A higher proportion of patients were discharged to hospital or home compared to the proportion of patients discharged back to the event. Patients from rural/regional locations (accounting for 15% of all patients) were

  14. Metal-contaminated resuspended sediment particles are a minor metal-uptake route for the Sydney rock oyster (Saccostrea glomerata)--A mesocosm study, Sydney Harbour estuary, Australia. (United States)

    Lee, J-H; Birch, G F; Simpson, S L


    Resuspension of surficial sediments is considered a key process influencing bioaccumulation of metals in filter-feeders in the contaminated Sydney Harbour estuary (Australia). However, previous investigations were unable to establish a significant relationship between metals in sediments or suspended particulate matter (SPM) and oyster tissue concentrations. This study used a 60-d laboratory mesocosm experiment to expose Sydney rock oysters, Saccostrea glomerata, to a natural range of SPM concentrations with different SPM-metal concentrations. Dissolved metal concentrations were low and the availability of algae provided as food was constant for all treatments. Tissue metal concentrations of Cu, Pb and Zn increased significantly, however, no relationship was determined between tissue metal concentrations in the oyster and either SPM or SPM-metal concentrations. The results indicated that exposure to resuspended contaminated sediment particles contributed little to the observed metal uptake. Dissolved or algae food sources appear to be more important for metal accumulation in these oysters.

  15. Metal accumulation in the greentail prawn, Metapenaeus bennettae, in Sydney and Port Hacking estuaries, Australia. (United States)

    Lewtas, K L M; Birch, G F; Foster-Thorpe, C


    Metal concentrations of the inshore greentail prawn, Metapenaeus bennettae, and surface sediments from locations within Sydney estuary and Port Hacking (Australia) were assessed for bioaccumulation and contamination. The current study aimed to assess metal concentrations in prawn tissue (tail muscle, exoskeleton, hepatopancreas and gills), relate whole body prawn tissue metal concentrations to sediment metal concentrations and animal size, as well as assess prawn consumption as a risk to human health. Metal concentrations were highest in sediment and prawns from contaminated locations (Iron Cove, Hen and Chicken Bay and Lane Cove) in Sydney estuary compared with the reference estuary (Port Hacking). Concentrations in sediments varied considerably between sites and between metals (As, Cd, Cr, Cu, Ni, Pb and Zn), and although concentrations exceeded Interim Sediment Quality Guideline-Low values, metals (As, Cd, Cr, Cu, Ni, Pb and Zn) were below Australian National Health and Medical Research Council human consumption guidelines in prawn tail muscle tissue. Metal concentrations in prawn tail muscle tissue were significantly different (p ≤ 0.05) amongst locations for Pb, Zn and Cd, and metal concentrations were generally highest in gills tissue, followed by the hepatopancreas, exoskeleton and tail muscle. The exoskeleton contained the highest Sr concentration; the hepatopancreas contained the highest As, Cu and Mo concentrations; and the gills contained the highest Al, Cr, Fe and Pb concentrations. Concentrations of Pb, As and Sr were significantly different (p ≤ 0.05) between size groups amongst locations.

    Stephanie Fletcher


    Full Text Available Background. Enteric protozoa are associated with diarrhoeal illnesses in humans; however there are no recent studies on their epidemiology and geographical distribution in Australia. This study describes the epidemiology of enteric protozoa in the state of New South Wales and incorporates spatial analysis to describe their distribution. Design and methods. Laboratory and clinical records from four public hospitals in Sydney for 910 patients, who tested positive for enteric protozoa over the period January 2007-December 2010, were identified, examined and analysed. We selected 580 cases which had residence post code data available, enabling us to examine the geographic distribution of patients, and reviewed the clinical data of 252 patients to examine possible links between protozoa, demographic and clinical features. Results. Frequently detected protozoa were Blastocystis spp. (57%, Giardia intestinalis (27% and Dientamoeba fragilis (12%. The age distribution showed that the prevalence of protozoa decreased with age up to 24 years but increasing with age from 25 years onwards. The geographic provenance of the patients indicates that the majority of cases of Blastocystis (53.1% are clustered in and around the Sydney City Business District, while pockets of giardiasis were identified in regional/rural areas. The distribution of cases suggests higher risk of protozoan infection may exist for some communities. Conclusions. These findings provide useful information for policy makers to design and tailor interventions to target high risk communities. Follow-up investigation into the risk factors for giardiasis in regional/rural area is needed.

  17. Growth and decline of shoreline industry in Sydney estuary (Australia) and influence on adjacent estuarine sediments. (United States)

    Birch, G F; Lean, J; Gunns, T


    Sydney estuary (Australia), like many urbanised waterways, is degraded due to an extended history of anthropogenic activity. Two major sources of contamination to this estuary are discharge by former shoreline industries and historic and contemporary catchment stormwater. The objectives of the present study were to document changes in shoreline land use from European settlement to the present day and determine the influence of this trend on the metal content of adjacent estuarine sediments. Temporal analysis of land use for seven time horizons between 1788 and 2010 showed rapid expansion of industry along much of the Sydney estuary foreshore soon after European settlement due to the benefits of easy and inexpensive access and readily available water for cooling and power. Shoreline industry attained maximum development in 1978 (32-km length) and declined rapidly to the present-day (9-km length) through redevelopment of industrial sites into medium- to high-density, high-value residential housing. Cores taken adjacent to 11 long-term industrial sites showed that past industrial practices contributed significantly to contamination of estuarine sediment. Subsurface metal concentrations were up to 35 times that of present-day surface sediment and over 100 times greater than natural background concentrations. Sedimentation rates for areas adjacent to shoreline industry were between 0.6 and 2.5 cm/year, and relaxation times were estimated at 50 to 100 years. Natural relaxation and non-disturbance of sediments may be the best management practice in most locations.

  18. Generation and expulsion of oils from Permian coals of the Sydney Basin, Australia

    Energy Technology Data Exchange (ETDEWEB)

    Ahmed, M.; Volk, H.; George, S.C.; Faiz, M.; Stalker, L. [CSIRO Petrology, Sydney, NSW (Australia)


    Organic geochemical and petrological assessment of coals/coaly shales and fine grained sediments, coupled with organic geochemical analyses of oil samples, all from Permo-Triassic sections of the Southern Sydney Basin (Australia), have enabled identification of the source for the widely distributed oil shows and oil seeps in this region. The Permian coals have higher hydrogen indices, higher liptinite contents, and much higher total organic matter extract yields than the fine grained sediments. A variety of source specific parameters obtained from n-alkanes, regular isoprenoids, terpanes, steranes and diasteranes indicate that the oil shows and seeps were generated and expelled predominantly from higher plant derived organic matter deposited in oxic environments. The source and maturity related biomarkers and aromatic hydrocarbon distributions of the oils are similar to those of the coals. The oil-coal relationship also is demonstrated by similarities in the carbon isotopic composition of the total oils, coal extracts, and their individual n-alkanes. Extracts from the Permo-Triassic fine grained sediments, on the other hand, have organic geochemical signatures indicative of mixed terrestrial and prokaryotic organic matter deposited in suboxic environments, which are significantly different from both the oils and coal extracts. The molecular signatures indicating the presence of prokaryotic organic matter in some of the coal extracts and oils may be due to thin sections of possibly calcareous lithologies interbedded within the coal measures. The genetic relationship between the oils and coals provides new evidence for the generation and expulsion of oils from the Permian coals and raises the possibility for commercial oil accumulations in the Permian and Early Triassic sandstones, potentially in the deeper offshore part of the Sydney Basin.

  19. Urban Green Infrastructure Impacts on Climate Regulation Services in Sydney, Australia

    Directory of Open Access Journals (Sweden)

    Brenda B. Lin


    Full Text Available In many parts of the world, urban planning has a renewed focus on addressing the multiple challenges associated with population growth and climate change. Focused on local needs and priorities, these planning processes are raising tensions between more compact and dense urban form to reduce energy use and associated emissions and the provision of urban green infrastructure for ecosystem services and climate adaptation. In this study, we investigated the spatial distribution of green infrastructure at the neighbourhood scale in Sydney, Australia and examined how a mix of landscape types (pavement, bare soil/dry grass, green grass, and tree cover affect temperature variation in three important locations for urban residents—around the home, in the roads and footpaths where people walk, and in parkland areas. Considering that residential and parkland areas contribute to the majority of green space in Sydney, it is important to understand how changes in landscape mix within these three neighbourhood areas will affect local temperature for urban residents. For residential houses, it was found that the percentage of tree canopy cover around the house had a significant negative relationship (p = 0.002 with surface temperatures of rooftops where greater tree cover led to lower rooftop temperatures. In streetscapes, both the percentage of tree cover (p < 0.0001 and the percentage of green grass (p < 0.0001 within the road segment had a significant negative relationship with the surface temperature of the road pavement. In the parks, the percentage of pavement (p < 0.0001 and the percentage of bare soil/dry grass (p < 0.0001 showed a significantly positive trend with land surface temperatures where greater land cover in the form of pavement and bare soil/dry grass led to higher temperatures. Collectively, these findings highlight the importance of promoting or reducing certain landscape covers depending on the land use type in order to maximise the

  20. Seroprevalence study of feline coronavirus in owned and feral cats in Sydney, Australia. (United States)

    Bell, E T; Toribio, J A L M L; White, J D; Malik, R; Norris, J M


    i) To establish the seroprevalence of Feline Coronavirus (FCoV) infection in two defined groups of cats in Sydney: owned and feral cats; ii) to identify factors associated with an increased risk of infection with FCoV; and iii) to establish the seroprevalence and FCoV antibody titres of owned cats with immunohistochemically confirmed feline infectious peritonitis (FIP). Prospective multi-institutional cross sectional study. Procedure Serum samples from owned cats presented to three inner city veterinary clinics in Sydney and feral cats from a colony in South Western Sydney over an 11-month period were tested for FCoV antibodies using the Immunocomb test kit. The relationship between serological score and six major factors (breed, age, gender, number of cats per household, living environment and health status) in the owned cat sample population was analysed and compared to cats with FIR RESULTS: The seroprevalence of FCoV infection in the sample population of owned and feral cats was 34% and 0%, respectively. The median Immunocomb scores of DSH, Persian, Siamese and Devon Rex cats were significantly lower than that of Burmese, BSH, Abyssinian, Birman, Ragdoll and Russian Blue. The median lmmunocomb score of pedigree cats less than 2 years-of-age was significantly higher than for pedigree cats greater than 2 years-of-age. This distinction was not evident in DSH cats in these age groups. The number of cats per household at the time of blood collection had a strong positive association with Immunocomb score. The median Immunocomb score of cats with immunohistochemically confirmed FIP was significantly higher than cats in the sample population of owned cats but there was sufficient overlap between these two groups to make definitive diagnosis of FIP by serology impossible. This represents the first seroprevalence study of FCoV in Australia. The major determinants of antibody score of owned cats identified in this study were breed, age and the number of cats per

  1. Representations of cycling in metropolitan newspapers - changes over time and differences between Sydney and Melbourne, Australia

    Directory of Open Access Journals (Sweden)

    Emilsen Adrian


    Full Text Available Abstract Background Cycling is important for health, transport, environmental and economic reasons. Newspaper reporting of cycling reflects and can influence public and policy maker attitudes towards resource allocation for cycling and cycling infrastructure, yet such coverage has not been systematically examined. Methods The Factiva electronic news archive was searched for articles referring to cycling published in four major metropolitan newspapers - two in Sydney and two in Melbourne, Australia, in the years from 1998 until 2008. After excluding articles not about cycling, there were 61 articles published in 1998, 45 in 1999, 51 in 2003, 82 in 2007 and 87 in 2008. Each article was coded for positive or negative orientation, and for framing of cyclists and cycling. Inter-rater reliability was calculated on a sample of 30 articles. Results Over the past decade there has been an increase in the reporting of cycling in the major newspapers in Sydney and Melbourne (from 106 in 1998/99 to 169 stories in 2007/08, with a significant increase in reporting of cycling in Melbourne, from 49 to 103 stories (p = 0.04. Recent reporting of cycling was generally positive (47% of articles, compared with 30% of articles which were negative and focused on benefits such as health and the environment. Three quarters of negative stories involved injury or death of a cyclist. The Sydney based The Daily Telegraph reported the most negative stories (n = 60. We found positive framing of 'cycling' was more widespread than negative, whereas framing of 'cyclists' was more negative than positive. Conclusions Quantity of reporting of cycling varies over time and by newspaper, and even between newspapers in different cities owned by the same media company. News coverage appears to reflect developments in the different cities, with increases in positive reporting of cycling in Melbourne following increases in cycling in that city. Negative cycling newspaper stories may deter

  2. Sex partying among gay men in Sydney, Melbourne and Brisbane, Australia. (United States)

    Prestage, Garrett; Down, Ian; Grulich, Andrew; Zablotska, Iryna


    Group sex is relatively common among gay men, and is a likely risk factor for infection with HIV and other sexually transmissible infections (STI). The 5,432 participants in the 2008 Gay Community Periodic Survey in Sydney, Melbourne and Brisbane, Australia, were asked about their participation in group sex. Nearly half (44.0%) of those who reported sex with casual male partners in the previous 6 months also reported engaging in group sex. Among other factors, using drugs odds ratios (OR) and confidence intervals (CI) (OR = 1.89, CI = 1.61-2.21), being HIV-positive (OR = 1.62, CI = 1.13-2.32), and engaging in anal intercourse, both with a condom (OR = 3.03, CI = 2.46-3.73) and without a condom (OR = 5.68, CI = 4.53-7.12) were independently associated with having engaged in group sex. This study suggests that gay men who engage in group sex represent an important priority for targeted HIV and STI prevention activities and research.

  3. Pricing the urban cooling benefits of solar panel deployment in Sydney, Australia (United States)

    Ma, S.; Goldstein, M.; Pitman, A. J.; Haghdadi, N.; MacGill, I.


    Cities import energy, which in combination with their typically high solar absorption and low moisture availability generates the urban heat island effect (UHI). The UHI, combined with human-induced warming, makes our densely populated cities particularly vulnerable to climate change. We examine the utility of solar photovoltaic (PV) system deployment on urban rooftops to reduce the UHI, and we price one potential value of this impact. The installation of PV systems over Sydney, Australia reduces summer maximum temperatures by up to 1 °C because the need to import energy is offset by local generation. This offset has a direct environmental benefit, cooling local maximum temperatures, but also a direct economic value in the energy generated. The indirect benefit associated with the temperature changes is between net AUD$230,000 and $3,380,000 depending on the intensity of PV systems deployment. Therefore, even very large PV installations will not offset global warming, but could generate enough energy to negate the need to import energy, and thereby reduce air temperatures. The energy produced, and the benefits of cooling beyond local PV installation sites, would reduce the vulnerability of urban populations and infrastructure to temperature extremes. PMID:28262843

    Gay and bisexual men (GBM) report higher rates of methamphetamine use compared to heterosexual men, and thus have a heightened risk of developing problems from their use. We examined treatment outcomes among GBM clients receiving outpatient counseling at a lesbian, gay, bisexual, transgender and intersex (LGBTI)-specific, harm reduction treatment service in Sydney, Australia. GBM receiving treatment for methamphetamine use from ACON's Substance Support Service between 2012-15 (n = 101) were interviewed at treatment commencement, and after 4 sessions (n = 60; follow-up 1) and 8 sessions (n = 32; follow-up 2). At each interview, clients completed measures of methamphetamine use and dependence, other substance use, injecting risk practices, psychological distress and quality of life. The median age of participants was 41 years and 56.4% identified as HIV-positive. Participants attended a median of 5 sessions and attended treatment for a median of 112 days. There was a significant reduction in the median days of methamphetamine use in the previous 4 weeks between baseline (4 days), follow-up 1 (2 days) and follow-up 2 (2 days; p = .001). There was a significant reduction in the proportion of participants reporting methamphetamine dependence between baseline (92.1%), follow-up 1 (78.3%) and follow-up 2 (71.9%, p LGBTI-specific treatment service.

  5. Non-fatal cocaine overdose among injecting and non-injecting cocaine users in Sydney, Australia. (United States)

    Kaye, Sharlene; Darke, Shane


    To investigate the frequency of non-fatal cocaine overdose, and responses to overdoses, among injecting and non-injecting cocaine users. Cross-sectional study. Sydney, Australia. Two hundred current cocaine users. Structured interview. Thirteen per cent of the sample had overdosed on cocaine, 7% in the preceding 12 months. Cocaine injectors were more likely to have overdosed, both ever (17 v 6%) and in the preceding 12 months (9 v 3%). The most common symptoms of overdose were palpitations (68%), intense sweating (44%) and seizures (40%). The use of other drugs in combination with cocaine prior to the most recent overdose was prevalent (64%), most commonly opioids (40%), alcohol (24%) and cannabis (24%). Those who had overdosed were more likely to be female, had longer cocaine use careers, had used more cocaine in the preceding month and preceding 6 months, had higher levels of cocaine dependence and more extensive polydrug use. Twenty-four per cent had witnessed a cocaine overdose, 13% in the preceding 12 months. Injectors were more likely to have witnessed overdoses, both ever (35% v 8%) and in the preceding 12 months (20% v 3%). Experience of, and exposure to, overdose were not rare events. Cocaine users need to be aware of the possibility and nature of overdose, and that cocaine overdose can occur irrespective of method of use. There is a need to emphasise the potential danger of combining cocaine with other drugs.

  6. Pricing the urban cooling benefits of solar panel deployment in Sydney, Australia (United States)

    Ma, S.; Goldstein, M.; Pitman, A. J.; Haghdadi, N.; MacGill, I.


    Cities import energy, which in combination with their typically high solar absorption and low moisture availability generates the urban heat island effect (UHI). The UHI, combined with human-induced warming, makes our densely populated cities particularly vulnerable to climate change. We examine the utility of solar photovoltaic (PV) system deployment on urban rooftops to reduce the UHI, and we price one potential value of this impact. The installation of PV systems over Sydney, Australia reduces summer maximum temperatures by up to 1 °C because the need to import energy is offset by local generation. This offset has a direct environmental benefit, cooling local maximum temperatures, but also a direct economic value in the energy generated. The indirect benefit associated with the temperature changes is between net AUD$230,000 and $3,380,000 depending on the intensity of PV systems deployment. Therefore, even very large PV installations will not offset global warming, but could generate enough energy to negate the need to import energy, and thereby reduce air temperatures. The energy produced, and the benefits of cooling beyond local PV installation sites, would reduce the vulnerability of urban populations and infrastructure to temperature extremes.

  7. Alunite formation within silica stalactites from the Sydney Region, South-eastern Australia

    Directory of Open Access Journals (Sweden)

    Wray Robert A.L.


    Full Text Available This paper presents X-ray diffraction and SEM evidence for the formation of alunite, and possibly small quantities of natroalunite, withinopal-A stalactites formed on quartz sandstone near Sydney in south-eastern, Australia. Alunite has been reported as a speleogenetic mineralfrom sediments within a number of caves around the world, but this is believed to be the first report of speleothemic alunite in opalinesilica speleothems. Individual alunite crystals have not been visually identified, but SEM X-ray element mapping suggests the alunite hasformed amongst kaolinite clay. Sedimentary alunite and natroalunite formation is usually associated with the reaction of sulphuric acidon illite, smectite and kaolinite clay materials. In this location groundwater sulphate levels are not high, but evaporative concentration ofstalactite drip-water containing small amounts of sulphuric acid generated by oxidization of pyrite might lower the pH to a level sufficientlyacidic for conversion of kaolinite or illite to alunite. The ferrolysis of hydrous Fe2+-oxides, or the biochemical activities of bacteria or othermicro-organisms, also provide conceivable pathways for the generation of pH sufficiently low to contribute to alunite formation. The occurrenceof alunite in these silica stalactites, whilst unusual, is consistent with the normal silica stalactite-forming process in this region, and inaccord with observations of the authigenic formation of alunite and groundwater opal in weathering profiles elsewhere

    Full Text Available In 2014, influenza activity was high in New South Wales (NSW, Australia, and 21 443 people were hospitalized with a diagnosis of influenza-associated pneumonia. This translates to a rate of 252.4 cases per 100 000 population. More than 18 000 cases of laboratory-confirmed influenza were reported in NSW. The majority were influenza A, dominated by A/H3N2 subtype. There were also 111 influenza outbreaks in aged care facilities (ACFs reported in NSW in 2014, the highest number on record. Elderly residents in ACFs experience high rates of morbidity and mortality during influenza outbreaks. They are at increased risk of developing complications due to underlying diseases. These residents also have an increased risk of infection because of the institutional environment they share with many other residents and staff. Furthermore, impaired oral intake, limited dexterity and altered consciousness may limit treatment options when they are infected. The Australian Government’s Department of Health and Ageing (DHA has issued specific guidelines for prevention and control of influenza outbreaks in residential care facilities. While ACFs have primary responsibility for managing outbreaks, Public Health Units (PHUs are required to promote ACF compliance with these guidelines and facilitate delivery and administration of antivirals. However, effective influenza prophylaxis and other timely interventions can only occur if PHUs are notified in a timely manner. DHA guidelines indicate influenza outbreaks in ACFs are to be reported to PHUs. However, under NSW public health legislation, reporting of outbreaks in ACFs is not mandatory. In this report we investigated whether there were outbreaks that were not reported to the South Western Sydney Local Health Districts PHU during the 2014 influenza season.

  10. Quantifying reduction in ecological risk in Penrhyn Estuary, Sydney, Australia, following groundwater remediation. (United States)

    Hunt, James; Birch, Gavin; Warne, Michael


    The environmental risk associated with discharge of contaminated groundwater containing a complex mixture of at least 14 volatile chlorinated hydrocarbons (VCHs) to Penrhyn Estuary, Sydney, Australia has previously been assessed. That probabilistic ecological risk assessment (ERA) was undertaken using surface water monitoring data from 2004 to 2005. Subsequently, in 2006, a groundwater remediation system was installed and commissioned to prevent further discharge of VCHs into the estuary. The present study assessed the ecological risk posed to the estuary after 2006 to evaluate the success of the remediation system. The ERA was undertaken using toxicity data derived from direct toxicity assessment (DTA) of preremediation contaminated groundwater using indigenous species, exposure data from surface water monitoring between 2007 and 2008 and the joint probability curve (JPC) methodology. The risk posed was measured in 4 zones of the entire site: source area (2), tributary (2), the inner estuary and outer estuary at high, low, and a combination of high and low tides. In the 2 source areas, risk decreased by over 2 and over 1 orders of magnitude to maximum values of less than 0.5%. In 1 estuary, risk decreased by over 1 order of magnitude, from a maximum of 36% to a maximum of 2.3%. At the other tributary and both the inner and outer estuaries, the risk decreased to less than 1%, regardless of the tide. This analysis revealed that the remediation system was very effective and that the standard level of protection required for slightly to moderately affected ecosystems (95% of species) by the Australian and New Zealand Guidelines for Fresh and Marine Water Quality was met postremediation.

  11. Estimates of potential childhood lead exposure from contaminated soil using the US EPA IEUBK Model in Sydney, Australia. (United States)

    Laidlaw, Mark A S; Mohmmad, Shaike M; Gulson, Brian L; Taylor, Mark P; Kristensen, Louise J; Birch, Gavin


    Surface soils in portions of the Sydney (New South Wales, Australia) urban area are contaminated with lead (Pb) primarily from past use of Pb in gasoline, the deterioration of exterior lead-based paints, and industrial activities. Surface soil samples (n=341) were collected from a depth of 0-2.5cm at a density of approximately one sample per square kilometre within the Sydney estuary catchment and analysed for lead. The bioaccessibility of soil Pb was analysed in 18 samples. The blood lead level (BLL) of a hypothetical 24 month old child was predicted at soil sampling sites in residential and open land use using the United States Environmental Protection Agency (US EPA) Integrated Exposure Uptake and Biokinetic (IEUBK) model. Other environmental exposures used the Australian National Environmental Protection Measure (NEPM) default values. The IEUBK model predicted a geometric mean BLL of 2.0±2.1µg/dL using measured soil lead bioavailability measurements (bioavailability =34%) and 2.4±2.8µg/dL using the Australian NEPM default assumption (bioavailability =50%). Assuming children were present and residing at the sampling locations, the IEUBK model incorporating soil Pb bioavailability predicted that 5.6% of the children at the sampling locations could potentially have BLLs exceeding 5µg/dL and 2.1% potentially could have BLLs exceeding 10µg/dL. These estimations are consistent with BLLs previously measured in children in Sydney. Copyright © 2017 Elsevier Inc. All rights reserved.

  14. Non-stationarity in daily and sub-daily intense rainfall – Part 1: Sydney, Australia

    Directory of Open Access Journals (Sweden)

    D. Jakob


    Full Text Available This study was driven by a need to clarify how variations in climate might affect intense rainfall and the potential for flooding. Sub-daily durations are of particular interest for urban applications. Worldwide, few such observation-based studies exist, which is mainly due to limitations in data. While there are still large discrepancies between precipitation data sets from observations and models, both show that there is a tendency for moist regions to become wetter and for dry regions to become drier. However, changes in extreme conditions may show the opposite sign to those in average conditions. Where changes in observed intense precipitation have been studied, this has typically been for daily durations or longer.

    The purpose of this two-part study is to examine daily and sub-daily rainfall extremes for evidence of non-stationarity. Here the problem was addressed by supplementing one long record (Part 1 by a set of shorter records for a 30-yr concurrent period (Part 2. Variations in frequency and magnitude of rainfall extremes across durations from 6 min to 72 h were assessed using data from sites in the south-east of Australia. For the analyses presented in this paper, a peaks-over-threshold approach was chosen since it allows investigating changes in frequency as well as magnitude. Non-parametric approaches were used to assess changes in frequency, magnitude, and quantile estimates as well as the statistical significance of changes for one station (Sydney Observatory Hill for the period 1921 to 2005. Deviations from the long-term average vary with season, duration, and threshold. The effects of climate variations are most readily detected for the highest thresholds. Deviations from the long-term average tend to be larger for frequencies than for magnitudes, and changes in frequency and magnitude may have opposite signs.

    Investigations presented in this paper show that variations in frequency and magnitude of events at

  16. Reliability and Cost Analysis of a Rainwater Harvesting System in Peri-Urban Regions of Greater Sydney, Australia

    Directory of Open Access Journals (Sweden)

    Evan Hajani


    Full Text Available In large cities, rainwater tanks are used to save mains water, but in peri-urban and rural areas, rainwater tanks are used as a sole water supply for many households, as these regions often do not have any other means of water supply. This paper investigates the performance of a rainwater harvesting system (RWHS in peri-urban regions of Greater Sydney, Australia. Considering the daily rainfall data over the entire period of record at ten different locations, it has been found that a 5 kL tank can meet 96% to 99% of the demand for toilet and laundry use depending on the location in Greater Sydney regions. However, in the driest year, a 5 kL tank can meet 69% to 99% of toilet and laundry demand depending on the location. Based on the results of life cycle cost analysis, it has been found that a 5 kL tank has the highest benefit–cost ratio (ranging from 0.86 to 0.97 among the eight possible tank sizes examined in this study. Interestingly, for a 5 kL tank, with a combined use (i.e., toilet, laundry and irrigation, the current water price in Sydney needs to be increased by 3% to 16% to achieve a benefit–cost ratio exceeding one. A set of regression equations are developed which can be used to estimate reliability using the average annual rainfall data at any arbitrary location in the peri-urban regions of Greater Sydney. The method presented in this paper can also be applied to other Australian states and other countries to estimate water savings and reliability of a RWHS using daily rainfall data.

  17. The evolving market structures of gambling: case studies modelling the socioeconomic assignment of gaming machines in Melbourne and Sydney, Australia. (United States)

    Marshall, David C; Baker, Robert G V


    The expansion of gambling industries worldwide is intertwined with the growing government dependence on gambling revenue for fiscal assignments. In Australia, electronic gaming machines (EGMs) have dominated recent gambling industry growth. As EGMs have proliferated, growing recognition has emerged that EGM distribution closely reflects levels of socioeconomic disadvantage. More machines are located in less advantaged regions. This paper analyses time-series socioeconomic distributions of EGMs in Melbourne, Australia, an immature EGM market, and then compares the findings with the mature market in Sydney. Similar findings in both cities suggest that market assignment of EGMs transcends differences in historical and legislative environments. This indicates that similar underlying structures are evident in both markets. Modelling the spatial structures of gambling markets provides an opportunity to identify regions most at risk of gambling related problems. Subsequently, policies can be formulated which ensure fiscal revenue from gambling can be better targeted towards regions likely to be most afflicted by excessive gambling-related problems.

  18. Modeling of a lot scale rainwater tank system in XP-SWMM: a case study in Western Sydney, Australia. (United States)

    van der Sterren, Marlène; Rahman, Ataur; Ryan, Garry


    Lot scale rainwater tank system modeling is often used in sustainable urban storm water management, particularly to estimate the reduction in the storm water run-off and pollutant wash-off at the lot scale. These rainwater tank models often cannot be adequately calibrated and validated due to limited availability of observed rainwater tank quantity and quality data. This paper presents calibration and validation of a lot scale rainwater tank system model using XP-SWMM utilizing data collected from two rainwater tank systems located in Western Sydney, Australia. The modeling considers run-off peak and volume in and out of the rainwater tank system and also a number of water quality parameters (Total Phosphorus (TP), Total Nitrogen (TN) and Total Solids (TS)). It has been found that XP-SWMM can be used successfully to develop a lot scale rainwater system model within an acceptable error margin. It has been shown that TP and TS can be predicted more accurately than TN using the developed model. In addition, it was found that a significant reduction in storm water run-off discharge can be achieved as a result of the rainwater tank up to about one year average recurrence interval rainfall event. The model parameter set assembled in this study can be used for developing lot scale rainwater tank system models at other locations in the Western Sydney region and in other parts of Australia with necessary adjustments for the local site characteristics.

    Robertson, J Gordon; Tango, William J; Tuthill, Peter G; Warrington, Benjamin A; Kok, Yitping; Rizzuto, Aaron C; Cheetham, Anthony; Jacob, Andrew P


    This paper presents an overview of recent progress at the Sydney University Stellar Interferometer (SUSI). Development of the third-generation PAVO beam combiner has continued. The MUSCA beam combiner for high-precision differential astrometry using visible light phase referencing is under active development and will be the subject of a separate paper. Because SUSI was one of the pioneering interferometric instruments, some of its original systems are old and have become difficult to maintain. We are undertaking a campaign of modernization of systems: (1) an upgrade of the Optical Path Length Compensator IR laser metrology counter electronics from a custom system which uses an obsolete single-board computer to a modern one based on an FPGA interfaced to a Linux computer - in addition to improving maintainability, this upgrade should allow smoother motion and higher carriage speeds; (2) the replacement of the aged single-board computer local controllers for the siderostats and the longitudinal dispersion compe...

    The global city thesis and the migration thesis concern two important dimensions of the impacts of contemporary globalization on cities. The two theses are intrinsically linked. The central question is how we should approach migration in the new context of the global city, and how we should articulate their interrelationships. To address this question, we construct an integrative analytical framework linking global city and migration, and empirically apply it to Sydney. We build a set of inde...

  1. Impact of ambient air pollution on gestational age is modified by season in Sydney, Australia. (United States)

    Jalaludin, Bin; Mannes, Trish; Morgan, Geoffrey; Lincoln, Doug; Sheppeard, Vicky; Corbett, Stephen


    The effect of individual pollutants and the period(s) during pregnancy when pollutant levels are likely to have most impact on preterm birth is not clear. We evaluated the effect of prenatal exposure to six common urban air pollutants in the Sydney metropolitan area on preterm birth. We obtained information on all births in metropolitan Sydney between January 1, 1998 and December 31, 2000. For each birth, exposure to each air pollutant was estimated for the first trimester, the three months preceding birth, the first month after the estimated date of conception and the month prior to delivery. Gestational age was analysed as a categorical variable in logistic regression models. There were 123,840 singleton births in Sydney in 1998-2000 and 4.9% were preterm. Preterm birth was significantly associated with maternal age, maternal smoking, male infant, indigenous status and first pregnancy. Air pollutant levels in the month and three months preceding birth had no significant effect on preterm birth after adjusting for maternal and infant covariates. Ozone levels in the first trimester of pregnancy and spring months of conception and sulphur dioxide were associated with increased risks for preterm births. Nitrogen dioxide was associated with a decreased risk of preterm births. We found more protective than harmful associations between ambient air pollutants and preterm births with most associations non-significant. In view of these inconsistent associations, it is important to interpret the harmful effects with caution. If our results are confirmed by future studies then it will be imperative to reduce Sydney's already low air pollution levels even further.

  3. A Q fever cluster among workers at an abattoir in south-western Sydney, Australia, 2015

    Directory of Open Access Journals (Sweden)

    Heidi Lord


    Full Text Available Background: In September 2015, the Public Health Unit of the South Western Sydney Local Health District was notified of two possible Q fever cases. Case investigation identified that both cases were employed at an abattoir, and both cases advised that co-workers had experienced similar symptoms. Public Health Unit staff also recalled interviewing in late 2014 at least one other Q fever case who worked at the same abattoir. This prompted an outbreak investigation. Methods: The investigation incorporated active case finding, microbiological analysis, field investigation and a risk factor survey. Included cases were laboratory definitive or suspected cases occurring from October 2014 to October 2015, residing or working in south-western Sydney. A suspected case had clinically compatible illness, high-risk exposure and was epidemiologically linked to another confirmed case. A confirmed case included laboratory detection of C. burnetii. Results: Eight cases met the case definition with seven confirmed (including a deceased case and one suspected. The eight cases were all males who had been employed at an abattoir in south-western Sydney during their incubation period; symptom onset dates ranged from November 2014 to September 2015. Field investigation identified multiple potential risk factors at the abattoir, and the majority (75% of employees were not vaccinated against Q fever despite this high-risk setting. Conclusion: This cluster of Q fever in a single abattoir confirms the significance of this zoonotic disease as an occupational hazard among persons working in high-risk environments. Implementation of Q fever vaccination programmes should eliminate Q fever in high-risk occupational settings.

  4. Megaspores from the Late Permian, Lower Whybrow coal seam, Sydney Basin, Australia. (United States)



    More than 300 megaspore specimens have been recovered from samples from the Late Permian, Lower Whybrow coal seam of the Wittingham Coal Measures of the Sydney Basin. Only two species are recognised: Singhisporites surangei (Singh) Potonié, emend. and a new species of Singhisporites. Species distribution within the seam is controlled by a major fire event, as recognised by coal petrology and mesofossil content: Singhisporites surangei is dominant before the event, but following it, it is subordinate to the new species.The abundance of megaspores recovered has allowed recognition of the full range of morphologic variation of Singhisporites surangei, which encompasses specimens assigned previously to Singraulispora Pant & Mishra, 1986 and Mammilaespora Pant & Srivastava, 1961; both are regarded as junior synonyms of Singhisporites Potonié, emend. Ultrastructurally, the new species shows affinities with Mesozoic isoetalean megaspores.

  5. Measurement of fallout radionuclides, (239)(,240)Pu and (137)Cs, in soil and creek sediment: Sydney Basin, Australia. (United States)

    Smith, B S; Child, D P; Fierro, D; Harrison, J J; Heijnis, H; Hotchkis, M A C; Johansen, M P; Marx, S; Payne, T E; Zawadzki, A


    Soil and sediment samples from the Sydney basin were measured to ascertain fallout radionuclide activity concentrations and atom ratios. Caesium-137 ((137)Cs) was measured using gamma spectroscopy, and plutonium isotopes ((239)Pu and (240)Pu) were quantified using accelerator mass spectrometry (AMS). Fallout radionuclide activity concentrations were variable ranging from 0.6 to 26.1 Bq/kg for (137)Cs and 0.02-0.52 Bq/kg for (239+240)Pu. Radionuclides in creek sediment samples were an order of magnitude lower than in soils. (137)Cs and (239+240)Pu activity concentration in soils were well correlated (r(2) = 0.80) although some deviation was observed in samples collected at higher elevations. Soil ratios of (137)Cs/(239+240)Pu (decay corrected to 1/1/2014) ranged from 11.5 to 52.1 (average = 37.0 ± 12.4) and showed more variability than previous studies. (240)Pu/(239)Pu atom ratios ranged from 0.117 to 0.165 with an average of 0.146 (±0.013) and an error weighted mean of 0.138 (±0.001). These ratios are lower than a previously reported ratio for Sydney, and lower than the global average. However, these ratios are similar to those reported for other sites within Australia that are located away from former weapons testing sites and indicate that atom ratio measurements from other parts of the world are unlikely to be applicable to the Australian context.

    Baxter, Cg; Vogelnest, Lj; Doggett, Sl


    Infestations of larval and nymphal Ixodes spp. were identified in 16 dogs and 16 cats from several small animal clinics in Sydney. Cases occurred in late summer or autumn, peaking in February, and were seasonally recurrent in some individuals. Clinical signs of infestation included a papular dermatitis and irritation or pruritus that ranged from severe to mild or absent. The distribution of tick attachment tended to be cranial and ventral, with the face, legs, axillae and ventrum the most commonly affected sites. The estimated number of ticks in each infestation varied from less than 10 to more than 100. Basic morphological examination of ticks collected from affected animals was performed by attending veterinarians using light microscopy, and larvae and nymphs belonging to the Ixodes genus were identified. Ticks collected from 17 animals and submitted to the Department of Medical Entomology, Westmead Hospital were putatively identified as I. trichosuri (57%) and I. holocyclus (25%) larvae. Histopathological samples of attachment sites collected from three dogs and one cat were characterised by ticks attached in well-demarcated invaginations of the skin ('tick craters') associated with variable epidermal and/or dermal necrosis, focal eosinophilic intraspinous pustules, mild to marked eosinophilic and neutrophilic, superficial to deep, dermal perivascular to interstitial inflammation, and moderate to marked superficial dermal oedema and red cell extravasation. A range of topical acaricidal preparations, including fipronil and synthetic pyrethroids, were used for treatment.

    Chandra, Meena; Lord, Heidi; Fletcher-Lartey, Stephanie; Alexander, Kate; Egana, Nilva; Conaty, Stephen


    In September 2015, the South Western Sydney (SWS) Public Health Unit was notified of a cluster of Salmonella Typhimurium (STm) cases with a common multiple-locus variable-number tandem repeats analysis (MLVA) pattern. An investigation was conducted to identify a source and contain the outbreak. The cluster was initially identified through routine geographic information system cluster scanning applied to the New South Wales Notifiable Conditions Management System. Additional cases were identified through a complaint to local council about a bakery. The bakery was inspected and 48 environmental and food swabs were collected for analysis. A total of 26 suspected cases were identified, of which 14 were interviewed. STm MLVA type 3-16-9-11-523 was identified in 19 of 26 case stool specimens. Most cases (12/14) consumed bread rolls containing pork or chicken with chicken liver pâté and raw egg mayonnaise filling. Five cases identified a common bakery exposure. Environmental and food samples from the bakery isolated STm with an identical MLVA pattern. An STm cluster in SWS was investigated and found to be linked to Vietnamese bread rolls containing pork or chicken with chicken liver pâté and raw egg mayonnaise filling. Confirmation of a distinct MLVA pattern among STm isolates from clinical, food and environmental samples provided evidence to establish an epidemiological link between the cases and the implicated premises and informed public health action to contain the outbreak.

  9. The spatial domain of wildfire risk and response in the wildland urban interface in Sydney, Australia (United States)

    Price, O. F.; Bradstock, R. A.


    In order to quantify the risks from fire at the wildland urban interface (WUI), it is important to understand where fires occur and their likelihood of spreading to the WUI. For each of the 999 fires in the Sydney region we calculated the distance between the ignition and the WUI, the fire's weather and wind direction and whether it spread to the WUI. The likelihood of burning the WUI was analysed using binomial regression. Weather and distance interacted such that under mild weather conditions, the model predicted only a 5% chance that a fire starting >2.5 km from the interface would reach it, whereas when the conditions are extreme the predicted chance remained above 30% even at distances >10 km. Fires were more likely to spread to the WUI if the wind was from the west and in the western side of the region. We examined whether the management responses to wildfires are commensurate with risk by comparing the distribution of distance to the WUI of wildfires with roads and prescribed fires. Prescribed fires and roads were concentrated nearer to the WUI than wildfires as a whole, but further away than wildfires that burnt the WUI under extreme weather conditions (high risk fires). Overall, 79% of these high risk fires started within 2 km of the WUI, so there is some argument for concentrating more management effort near the WUI. By substituting climate change scenario weather into the statistical model, we predicted a small increase in the risk of fires spreading to the WUI, but the increase will be greater under extreme weather. This approach has a variety of uses, including mapping fire risk and improving the ability to match fire management responses to the threat from each fire. They also provide a baseline from which a cost-benefit analysis of complementary fire management strategies can be conducted.

    Full Text Available BACKGROUND: While morbidity outcomes for major disease categories during extreme heat have received increasing research attention, there has been very limited investigation at the level of specific disease subcategories. METHODOLOGY/PRINCIPAL FINDINGS: We analyzed daily hospital admissions for cardiovascular (CVD, respiratory (RD, genitourinary (GU and mental diseases (MD, diabetes (DIA, dehydration (DEH and 'the effects of heat and light' (HEAT in Sydney between 1991 and 2009. We further investigated the sensitivity to heat of subcategories within the major disease groups. We defined hot days as those with temperatures in the 95(th and 99(th percentiles within the study period. We applied time-stratified case-crossover analysis to compare the hospital admissions on hot days with those on non-hot days matched by day of the week. We calculated the odds ratios (OR of admissions between the two types of days, accounting for other environmental variables (relative humidity, ozone and particulate matter and non-environmental trends (public and school holidays. On hot days, hospital admissions increased for all major categories except GU. This increase was not shared homogeneously across all diseases within a major category: within RD, only 'other diseases of the respiratory system' (includes pleurisy or empyema increased significantly, while admissions for asthma decreased. Within MD, hospital admissions increased only for psychoses. Admissions due to some major categories increased one to three days after a hot day (e.g., DIA, RD and CVD and on two and three consecutive days (e.g., HEAT and RD. CONCLUSIONS/SIGNIFICANCE: High ambient temperatures were associated with increased hospital admissions for several disease categories, with some within-category variation. Future analyses should focus on subgroups within broad disease categories to pinpoint medical conditions most affected by ambient heat.

  11. Correlates of susceptibility to hepatitis B among people who inject drugs in Sydney, Australia. (United States)

    Deacon, Rachel M; Topp, Libby; Wand, Handan; Day, Carolyn A; Rodgers, Craig; Haber, Paul S; van Beek, Ingrid; Maher, Lisa


    Despite a safe, effective vaccine, hepatitis B virus (HBV) vaccination coverage remains low among people who inject drugs (PWID). Characteristics of participants screened for a trial investigating the efficacy of financial incentives in increasing vaccination completion among PWID were examined to inform targeting of vaccination programs. Recruitment occurred at two health services in inner-city Sydney that target PWID. HBV status was confirmed via serological testing, and questionnaires elicited demographic, drug use, and HBV risk data. Multinomial logistic regression was utilized to determine variables independently associated with HBV status. Of 172 participants, 64% were susceptible, 17% exposed (HBV core antibody-positive), and 19% demonstrated evidence of prior vaccination (HBV surface antibody ≥ 10 mIU/ml). Compared with exposed participants, susceptible participants were significantly more likely to be aged less than 35 years and significantly less likely to be receiving current opioid substitution therapy (OST) and to test hepatitis C antibody-positive. In comparison to vaccinated participants, susceptible participants were significantly more likely to be male and significantly less likely to report daily or more frequent injecting, current OST, and prior awareness of HBV vaccine. HBV vaccination uptake could potentially be increased by targeting younger, less frequent injectors, particularly young men. In addition to expanding vaccination through OST, targeting "at risk" youth who are likely to have missed adolescent catch-up programs may be an important strategy to increase coverage. The lack of an association between incarceration and vaccination also suggests increasing vaccination uptake and completion in adult and juvenile correctional facilities may also be important.

  12. Perceived discrimination and injecting risk among people who inject drugs attending Needle and Syringe Programmes in Sydney, Australia. (United States)

    Wilson, Hannah; Brener, Loren; Mao, Limin; Treloar, Carla


    Previous research indicates that stigma and discrimination have negative consequences for both healthcare delivery and for health outcomes of people who inject drugs (PWID). Also important but not as well researched is the association between perceived discrimination and increased engagement in risky behaviours. This research aimed to explore whether perceived discrimination from workers in Needle and Syringe programmes (NSPs) is associated with increased engagement in injecting risk practices such as the sharing of injecting equipment. Convenience sampling was used across eight NSP sites within Western Sydney, Australia. All clients who attended one of the NSPs were eligible to participate. A total of 236 clients completed the survey. Perceived discrimination from NSP staff was found to be significantly associated with some injecting risk practices. Respondents who reported greater perceived discrimination from NSP staff were significantly more likely to report being injected by someone else after they had injected themselves (OR 1.2, 95%CI 1.1-1.3) and reusing a needle or syringe (OR 1.1, 95%CI 1.0-1.3) in the last month. Although clients reported perceiving more discrimination from general health workers than from NSP workers (12.8 vs. 10.2, t=7.739, df=226, pjudgemental, their clients may still have a heightened sensitivity to discrimination which can then have consequences for on-going engagement in risk practices.

  13. The effectiveness of community-based cycling promotion: findings from the Cycling Connecting Communities project in Sydney, Australia

    Directory of Open Access Journals (Sweden)

    Merom Dafna


    Full Text Available Abstract Background Encouraging cycling is an important way to increase physical activity in the community. The Cycling Connecting Communities (CCC Project is a community-based cycling promotion program that included a range of community engagement and social marketing activities, such as organised bike rides and events, cycling skills courses, the distribution of cycling maps of the area and coverage in the local press. The aim of the study was to assess the effectiveness of this program designed to encourage the use of newly completed off-road cycle paths through south west Sydney, Australia. Methods The evaluation used a quasi-experimental design that consisted of a pre- and post-intervention telephone survey (24 months apart of a cohort of residents (n = 909 in the intervention area (n = 520 (Fairfield and Liverpool and a socio-demographically similar comparison area (n = 389 (Bankstown. Both areas had similar bicycle infrastructure. Four bicycle counters were placed on the main bicycle paths in the intervention and comparison areas to monitor daily bicycle use before and after the intervention. Results The telephone survey results showed significantly greater awareness of the Cycling Connecting Communities project (13.5% vs 8.0%, p Conclusion Despite relatively modest resources, the Cycling Connecting Communities project achieved significant increases in bicycle path use, and increased cycling in some sub-groups. However, this community based intervention with limited funding had very limited reach into the community and did not increase population cycling levels.

  14. Methyl 3-[3',4'-(methylenedioxy)phenyl]-2-methyl glycidate: an ecstasy precursor seized in Sydney, Australia. (United States)

    Collins, Michael; Heagney, Aaron; Cordaro, Frank; Odgers, David; Tarrant, Gregory; Stewart, Samantha


    Five 44 gallon drums labeled as glycidyl methacrylate were seized by the Australian Customs Service and the Australian Federal Police at Port Botany, Sydney, Australia, in December 2004. Each drum contained a white, semisolid substance that was initially suspected to be 3,4-methylenedioxymethylamphetamine (MDMA). Gas chromatography-mass spectroscopy (GC/MS) analysis demonstrated that the material was neither glycidyl methacrylate nor MDMA. Because intelligence sources employed by federal agents indicated that this material was in some way connected to MDMA production, suspicion fell on the various MDMA precursor chemicals. Using a number of techniques including proton nuclear magnetic resonance spectroscopy ((1)H NMR), carbon nuclear magnetic resonance spectroscopy ((13)C NMR), GC/MS, infrared spectroscopy, and total synthesis, the unknown substance was eventually identified as methyl 3-[3',4'(methylenedioxy)phenyl]-2-methyl glycidate. The substance was also subjected to a published hydrolysis and decarboxylation procedure and gave a high yield of the MDMA precursor chemical, 3,4-methylenedioxyphenyl-2-propanone, thereby establishing this material as a "precursor to a precursor."

  15. Emerging contaminants (pharmaceuticals, personal care products, a food additive and pesticides) in waters of Sydney estuary, Australia. (United States)

    Birch, G F; Drage, D S; Thompson, K; Eaglesham, G; Mueller, J F


    The current investigation of marine water from 30 sites adjacent to stormwater outlets across the entire Sydney estuary is the first such research in Australia. The number of analytes detected were: 8/59 pharmaceutical compounds (codeine, paracetamol, tramadol, venlafaxine, propranolol, fluoxetine, iopromide and carbamazepine), 7/38 of the pesticides (2,4-dichlorophenoxyacetic acid (2,4-D), 3,4-dichloroaniline, carbaryl, diuron, 2-methyl-4-chlorophenoxyacetic acid (MCPA), mecoprop and simazine) and 0/3 of the personal care products (PCPs) analysed. An artificial sweetener (acesulfame) was detected, however none of the nine antibiotics analysed were identified. Sewage water is not discharged to this estuary, except infrequently as overflow during high-precipitation events. The presence of acesulfame (a recognised marker of domestic wastewater) and pharmaceuticals in water from all parts of the estuary after a dry period, suggests sewage water is leaking into the stormwater system in this catchment. The pesticides are applied to the environment and were discharged via stormwater to the estuary.

  16. Ambient particulate matter, landscape fire smoke, and emergency ambulance dispatches in Sydney, Australia. (United States)

    Salimi, Farhad; Henderson, Sarah B; Morgan, Geoffrey G; Jalaludin, Bin; Johnston, Fay H


    Emergency ambulance dispatches (EAD) are a novel outcome for evaluating the public health impacts of air pollution. We assessed the relationships between ambient particulate matter (PM) from all sources, PM from landscape fire smoke (LFS), and EADs likely to be associated with cardiorespiratory problems in the Sydney greater metropolitan region for an 11-year period from 2004 to 2015. EAD codes are assigned at the time of the call to emergency services using standard computer assisted algorithms. We assessed EADs coded as: breathing problems, chest pain, stroke or cerebrovascular accident (stroke), cardiac or respiratory arrest and death (arrest), and heart or defibrillator problems (other heart problems). Using a daily times series study design with a generalized linear Poisson regression model we quantified the association between EAD and daily PM2.5 from all sources (PM2.5,all) and PM2.5 primarily due to LFS (PM2.5,LFS). Increases of 10μg·m(-3) in PM2.5,all were positively associated with same day EAD for breathing problems (RR=1.03, 95% CI 1.02 to 1.04), arrest (RR=1.03, 95% CI 1.00 to 1.06), and chest pain (RR=1.01 CI 1.00 to 1.02) but not with other outcomes. Increases of 10μg·m(-3) PM2.5,LFS were also positively associated with breathing problems on the same day (RR=1.04, 95% CI 1.02 to 1.05) and other heart problems at lag of two days (RR=1.05, 95% CI 1.01 to 1.09). Emergency dispatches for breathing problems are associated with PM2.5,all and PM2.5,LFS and provide a sensitive end point for continued research and surveillance activities investigating the impacts of daily fluctuations in ambient PM2.5.

  17. Environmental impact of coal mining and coal seam gas production on surface water quality in the Sydney basin, Australia. (United States)

    Ali, A; Strezov, V; Davies, P; Wright, I


    The extraction of coal and coal seam gas (CSG) will generate produced water that, if not adequately treated, will pollute surface and groundwater systems. In Australia, the discharge of produced water from coal mining and related activities is regulated by the state environment agency through a pollution licence. This licence sets the discharge limits for a range of analytes to protect the environment into which the produced water is discharged. This study reports on the impact of produced water from coal mine activities located within or discharging into high conservation environments, such as National Parks, in the outer region of Sydney, Australia. The water samples upstream and downstream from the discharge points from six mines were taken, and 110 parameters were tested. The results were assessed against a water quality index (WQI) which accounts for pH, turbidity, dissolved oxygen, biochemical oxygen demand, total dissolved solids, total phosphorus, nitrate nitrogen and E .coli. The water quality assessment based on the trace metal contents against various national maximum admissible concentration (MAC) and their corresponding environmental impacts was also included in the study which also established a base value of water quality for further study. The study revealed that impacted water downstream of the mine discharge points contained higher metal content than the upstream reference locations. In many cases, the downstream water was above the Australia and New Zealand Environment Conservation Council and international water quality guidelines for freshwater stream. The major outliers to the guidelines were aluminium (Al), iron (Fe), manganese (Mn), nickel (Ni) and zinc (Zn). The WQI of surface water at and downstream of the discharge point was lower when compared to upstream or reference conditions in the majority of cases. Toxicology indices of metals present in industrial discharges were used as an additional tool to assess water quality, and the newly

  18. The discrepancy in concentration of metals (Cu, Pb and Zn) in oyster tissue (Saccostrea glomerata) and ambient bottom sediment (Sydney estuary, Australia). (United States)

    Birch, G F; Melwani, A; Lee, J-H; Apostolatos, C


    The current study aimed to examine the relationship between metals in sediments and metal bioaccumulation in oyster tissue in a highly-modified estuary (Sydney estuary, Australia). While extensive metal contamination was observed in surficial sediments, suspended particulate matter and oyster tissue, a significant relationship between these media could not be established. No relationship was determined between sediment quality guidelines and oyster size or weight, nor with human consumption levels for metals in oyster tissue. Moreover, oyster tissue metal concentrations varied greatly at a single locality over temporal scales of years. Oyster tissue at all 19 study sites exceeded consumptions levels for Cu. Bioaccumulation of metals in oyster tissue is a useful dynamic indicator of anthropogenic influence within estuaries, however oysters cannot be used in Sydney estuary as a valid biomonitor due to overriding internal regulation (homoestasis) by the animal, or by external natural (sediment resuspension) and anthropogenic (sewer/stormwater discharges) pressures, or both.

  19. Parental disease prevention health beliefs and triggers for keeping children home from childcare-a qualitative study in Sydney, Australia. (United States)

    King, C L; Leask, J


    Infectious diseases cause considerable morbidity and mortality in children less than 5 years of age. Children attending childcare centres are at increased risk of contracting infections. It is of public health interest to understand what triggers and underpins parental decisions to send an unwell child to childcare, with the obvious attendant risks to other children and childcare staff as well as the affected child. This study aimed to examine parents' disease prevention health beliefs and practices with a particular focus on how these factors influence childcare attendance decisions. Semistructured, in-depth interviews were conducted between June 2009 and May 2011 with parents who had at least one child under 5 years of age enrolled in a childcare centre. Six centres in the metropolitan area of Sydney, Australia, were selected to include parents from a range of demographic and socio-economic backgrounds. Forty-two interviews were conducted, recorded, and transcribed. Themes emerging from the data included "vitamin dirt," contagion, and contagion prevention and control. These interacted with parents' decision-making about childcare attendance, and parents made choices in a complex context of obligations to their child, social contract obligations to others, peer expectations, and the need to work. Vaccination received only scant mention as a preventive health measure. Decision-making by parents concerning childcare attendance was made without reference to any external guidelines. This study provides insights into parental disease prevention beliefs, behaviours, and decision-making. It reveals a need for policies to support parents with unwell children. In addition, resources and educative efforts to raise awareness of vaccination as a preventive health measure, and awareness of infectious disease contagion more broadly, would assist in providing parents with a greater evidence base for making decisions about childcare attendance when their child is unwell.

    To determine the body mass, cardiovascular and metabolic characteristics of young people presenting for mental healthcare. Cross-sectional assessments of body mass, cardiovascular and metabolic risk factors. Two primary-care based sites in Sydney, Australia for young people in the early stages of mental disorders. A clinical sample of young people (12-30 years) with mental health problems. Daily smoking rates, body mass index (BMI), blood glucose and lipids, blood pressure (BP) and pulse rate. Of 1005 young people who had their BMI determined (62% female; 19.0±3.5 years), three quarters (739/1005) also had BP recordings and one-third (298/1005) had blood sampling. Clinically, 775 were assigned to one of three diagnostic categories (anxious-depression: n=541; mania-fatigue, n=104; developmental-psychotic n=130). The profile of BMI categories approximated that of the comparable segments of the Australian population. Older age, lower levels of social functioning and higher systolic BP were all associated with high BMI. In a subset (n=129), current use of any psychotropic medication was associated (pyoung people presenting for mental healthcare. However, these young people do not demonstrate adverse cardiometabolic profiles. The high levels of smoking, and association of BMI with adverse social circumstances, suggest that risk factors for chronic disease are already present and likely to be compounded by medication and social disadvantage.

  1. Identification of Patients With Diabetes Who Benefit Most From a Health Coaching Program in Chronic Disease Management, Sydney, Australia, 2013 (United States)

    Delaney, Grace; Newlyn, Neroli; Pamplona, Elline; Hocking, Samantha L.; Glastras, Sarah J.; Fulcher, Gregory R.


    Introduction Chronic disease management programs (CDMPs) that include health coaching can facilitate and coordinate diabetes management. The aim of this study was to assess changes in patients’ general knowledge of diabetes, self-reported health status, diabetes distress, body mass index (BMI), and glycemic control after enrollment in a face-to-face CDMP group health coaching session (with telephone follow-up) compared with participation in telephone-only health coaching, during a 12-month period. Methods Patients with diabetes were enrolled in a health coaching program at Royal North Shore Hospital, Sydney, Australia, in 2013. Questionnaires were administered at baseline and at 3, 6, and 12 months, and the results were compared with baseline. Glycemic control, measured with glycated hemoglobin A1c (HbA1c) and BMI, were measured at baseline and 12 months. Results Overall, 238 patients attended a face-to-face CDMP session with telephone follow-up (n = 178) or participated in telephone-only health coaching (n = 60). We found no change in BMI in either group; however, HbA1c levels in patients with baseline above the current recommended target (>7%) decreased significantly from 8.5% (standard deviation [SD], 1.0%) to 7.9% (SD, 1.0%) (P = .03). Patients with the lowest self-reported health status at baseline improved from 4.4 (SD, 0.5) to 3.7 (SD, 0.9) (P = .001). Diabetes knowledge improved in all patients (24.4 [SD, 2.4] to 25.2 [SD, 2.4]; P diabetes distress decreased among those with the highest levels of distress at baseline (3.0 [SD, 0.4] vs 3.8 [SD, 0.6]; P = .003). Conclusion Diabetes health coaching programs can improve glycemic control and reduce diabetes distress in patients with high levels of these at baseline. PMID:28253473

    Maher Lisa


    Full Text Available Abstract Background Ethnic Vietnamese injecting drug users (IDUs in Australia draw on a range of beliefs and etiologic models, sometimes simultaneously, in order to make sense of health and illness. These include understandings of illness as the result of internal imbalances and Western concepts of disease causation including germ/pollution theory. Methods Observational fieldwork and in-depth interviews were conducted between 2001 and 2006 in neighbourhoods characterised by high proportions of Asian background IDUs and street-based drug markets. Eligibility criteria for the study were: 1 ethnic Vietnamese cultural background; 2 aged 16 years and over and; 3 injected drugs in the last 6 months. Results Participants commonly attempted to treat heroin overdose by withdrawing blood (rút máu from the body. Central to this practice are cultural beliefs about the role and function of blood in the body and its relationship to illness and health. Participants' beliefs in blood were strongly influenced by understandings of blood expressed in traditional Chinese and Vietnamese medicine. Many participants perceived Western drugs, particularly heroin, as "hot" and "strong". In overdose situations, it was commonly believed that an excessive amount of drugs (particularly heroin entered the bloodstream and traveled to the heart, making the heart work too hard. Withdrawing blood was understood to reduce the amount of drugs in the body which in turn reduced the effects of drugs on the blood and the heart. Conclusion The explanatory model of overdose employed by ethnic Vietnamese IDUs privileges traditional beliefs about the circulatory, rather than the respiratory, system. This paper explores participants' beliefs about blood, the effects of drugs on blood and the causes of heroin overdose in order to document the explanatory model of overdose used by ethnic Vietnamese IDUs. Implications for overdose prevention, treatment and management are identified and

Design Cross-sectional assessments of body mass, cardiovascular and metabolic risk factors. Setting Two primary-care based sites in Sydney, Australia for young people in the early stages of mental disorders. Participants A clinical sample of young people (12–30 years) with mental health problems. Outcome measures Daily smoking rates, body mass index (BMI), blood glucose and lipids, blood pressure (BP) and pulse rate. Results Of 1005 young people who had their BMI determined (62% female; 19.0±3.5 years), three quarters (739/1005) also had BP recordings and one-third (298/1005) had blood sampling.

The profile of BMI categories approximated that of the comparable segments of the Australian population. Older age, lower levels of social functioning and higher systolic BP were all associated with high BMI. In a subset (n=129), current use of any psychotropic medication was associated (p<0.05) with increased BMI. Almost one-third of cases were current daily smokers (compared to population rate of 11%). Males had a higher proportion of raised glucose and high-density lipoprotein (HDL) compared to females (9.3% and 34.1% vs 2.1% and 5.9%, respectively). Overall, there was no relationship between BMI and fasting glucose but significant relationships with triglycerides and HDL were noted. Furthermore, there were no significant relationships between diagnostic subgroup and metabolic profiles. Conclusions Daily smoking rates are increased among young people presenting for mental healthcare. However, these young people do not demonstrate adverse cardiometabolic profiles. The high levels of smoking, and association of BMI with adverse social circumstances, suggest that risk factors for chronic

    Full Text Available Abstract Background Urban renewal programs aim to target both the physical and social environments to improve the social capital, social connectedness, sense of community and economic conditions of residents of the neighbourhoods. We evaluated the impact of an urban renewal program on the health and well-being of residents of a socially disadvantaged community in south-western Sydney, Australia. Methods Pre- and post-urban renewal program surveys were conducted with householders by trained interviewers. The urban renewal program was conducted over 16 months and consisted of internal upgrades (including internal painting; replacement of kitchens, bathrooms and carpets; general maintenance, external upgrades (including property painting; new fencing, carports, letterboxes, concrete driveways, drainage and landscaping, general external maintenance, and social interventions such as community engagement activities, employment initiatives, and building a community meeting place. The questionnaire asked about demographic characteristics, self-reported physical activity, psychological distress, self-rated health, and perceptions of aesthetics, safety and walkability in the neighbourhood.

    Full Text Available Introduction. Cycling can be an enjoyable way to meet physical activity recommendations and is suitable for older people; however cycling participation by older Australians is low. This qualitative study explored motivators, enablers, and barriers to cycling among older people through an age-targeted cycling promotion program. Methods. Seventeen adults who aged 50–75 years participated in a 12-week cycling promotion program which included a cycling skills course, mentor, and resource pack. Semistructured interviews at the beginning and end of the program explored motivators, enablers, and barriers to cycling. Results. Fitness and recreation were the primary motivators for cycling. The biggest barrier was fear of cars and traffic, and the cycling skills course was the most important enabler for improving participants’ confidence. Reported outcomes from cycling included improved quality of life (better mental health, social benefit, and empowerment and improved physical health. Conclusions. A simple cycling program increased cycling participation among older people. This work confirms the importance of improving confidence in this age group through a skills course, mentors, and maps and highlights additional strategies for promoting cycling, such as ongoing improvement to infrastructure and advertising.

  6. The exposure of Sydney (Australia) to earthquake-generated tsunamis, storms and sea level rise: a probabilistic multi-hazard approach. (United States)

    Dall'Osso, F; Dominey-Howes, D; Moore, C; Summerhayes, S; Withycombe, G


    Approximately 85% of Australia's population live along the coastal fringe, an area with high exposure to extreme inundations such as tsunamis. However, to date, no Probabilistic Tsunami Hazard Assessments (PTHA) that include inundation have been published for Australia. This limits the development of appropriate risk reduction measures by decision and policy makers. We describe our PTHA undertaken for the Sydney metropolitan area. Using the NOAA NCTR model MOST (Method for Splitting Tsunamis), we simulate 36 earthquake-generated tsunamis with annual probabilities of 1:100, 1:1,000 and 1:10,000, occurring under present and future predicted sea level conditions. For each tsunami scenario we generate a high-resolution inundation map of the maximum water level and flow velocity, and we calculate the exposure of buildings and critical infrastructure. Results indicate that exposure to earthquake-generated tsunamis is relatively low for present events, but increases significantly with higher sea level conditions. The probabilistic approach allowed us to undertake a comparison with an existing storm surge hazard assessment. Interestingly, the exposure to all the simulated tsunamis is significantly lower than that for the 1:100 storm surge scenarios, under the same initial sea level conditions. The results have significant implications for multi-risk and emergency management in Sydney.

  8. Use of 210Pb and 137Cs to simultaneously constrain ages and sources of post-dam sediments in the Cordeaux reservoir, Sydney, Australia. (United States)

    Simms, Ava D; Woodroffe, Colin; Jones, Brian G; Heijnis, Henk; Mann, Rob A; Harrison, Jennifer


    Environmental radionuclides can be employed as tracers of sediment movement and delivery to water bodies such as lakes and reservoirs. The chronologies of sediments that have accumulated in the Cordeaux reservoir in Sydney, Australia, were determined by the rate of change of (210)Pb(ex) with depth and indicate slow accretion in the reservoir. The ratio of enrichment of radionuclides in sediment cores to (210)Pb(ex) and (137)Cs concentrations in a reference soil sample within the Cordeaux catchment indicates that the dominant source of sediment in the Cordeaux reservoir is surface erosion (detachment and removal of sediment at depths less than 30 cm). However, in the Kembla Creek arm of the reservoir a mixture of sources was detected and includes sheet and rill erosion together with sub-soil contributions. Implications for the utility of these radionuclide sedimentation assessments, especially where samples are limited, are that well-constrained chronologies and sources of soil erosion are facilitated.

  9. Field Evaluation of Melolure, a Formate Analogue of Cuelure, and Reassessment of Fruit Fly Species Trapped in Sydney, New South Wales, Australia. (United States)

    Dominiak, Bernard C; Campbell, Angus J; Jang, Eric B; Ramsey, Amanda; Fanson, Benjamin G


    In Australia, tephritids are usually attracted to either cuelure or methyl eugenol. Methyl eugenol is a very effective lure, but cuelure is less effective likely due to low volatility. A new formate analogue of cuelure, melolure, has increased volatility, resulting in improved efficacy with the melon fruit fly, Bactrocera cucurbitae Coquillett. We tested the efficacy of melolure with fruit fly species in Sydney as part of the National Exotic Fruit Fly Monitoring programme. This monitoring programme has 71 trap sites across Sydney, with each trap site comprising separate Lynfield traps containing either cuelure, methyl eugenol, or capilure lure. In 2008, an additional Lynfield trap with melolure plugs was added to seven sites. In 2009 and 2010, an additional Lynfield trap with melolure wicks was added to 11 trap sites and traps were monitored fortnightly for 2 yr. Capture rates for melolure traps were similar to cuelure traps for Dacus absonifacies (May) and Dacus aequalis (Coquillet), but melolure traps consistently caught fewer Bactrocera tryoni (Froggatt) than cuelure traps. However, trap sites with both a cuelure and melolure traps had increased capture rates for D. absonifacies and D. aequalis, and a marginally significant increase for B. tryoni. Melolure plugs were less effective than melolure wicks, but this effect may be related to lure concentration. The broader Bactrocera group species were attracted more to cuelure than melolure while the Dacus group species were attracted more to melolure than cuelure. There is no benefit in switching from cuelure to melolure to monitor B. tryoni, the most important fruit fly pest in Australia.

  10. Use of sediment risk and ecological/conservation value for strategic management of estuarine environments: Sydney estuary, Australia. (United States)

    Birch, Gavin F; Hutson, Philip


    Sediment mantling the floor of Sydney estuary contains a wide range of chemicals at highly elevated concentrations over extensive areas. Appropriate sediment management decisions are urgently required to prevent further degradation of sediment quality and to minimize resulting adverse ecological effects. The objective of the present work was to provide a systematic, estuary-wide assessment of sediment risk and ecological/conservation value throughout the harbor to guide sediment management decisions. Sediment risk is the likelihood of sediment chemistry causing adverse biological effects to bottom-dwelling animals and was conducted using national sediment quality guidelines (SQGs) for single contaminants and the mean SQG quotient approach to assess chemical mixtures. Sediment risk was negligible at the mouth of the estuary, but increased strongly landwards. The ecological/conservation value assessment was conducted to identify sites that warrant different levels of protection and was conducted using the value of ecological communities and priority waterway use. Consideration of these two parameters combined enabled the estuary to be prioritized for management attention. The prioritization and identification of appropriate management strategies were determined through the use of management matrices also based on sediment risk and ecological/conservation value. A computer package is being developed to provide managers with information on sediment risk, ecological/conservation value, the urgency and the type of management intervention required for any location in Sydney estuary, in real-time. This approach to estuarine management is unique and will greatly improve effective management of Sydney estuary, and other harbors in urgent need of management action and protection.

  11. Ethnomedicine and dominant medicine in multicultural Australia: a critical realist reflection on the case of Korean-Australian immigrants in Sydney

    Directory of Open Access Journals (Sweden)

    Ballis Harry


    Full Text Available Abstract Background Viewed through the micro focus of an interpretive lens, medical anthropology remains mystified because interpretivist explanations seriously downplay the given context in which individual health seeking-behaviours occur. This paper draws upon both the interpretivist and political economy perspectives to reflect on the ethno medical practices within the Korean-Australian community in Sydney. Methods We draw on research data collected between 1995 and 1997 for an earlier study of the use of biomedical and traditional medicine by Korean-Australians in Sydney. A total of 120 interviews were conducted with a range of participants, including biomedical doctors, traditional health professionals, Korean community leaders and Korean migrants representing a range of socio-economic backgrounds and migration patterns. Results and Discussion First, the paper highlights the extent to which the social location of migrants in a host society alters or restructures their initial cultural practices they bring with them. Second, taking hanbang medicine in the Korean-Australian community as an illustrative case, the paper explores the transformation of the dominant biomedicine in Australia as a result of the influx of ethnomedicine in the era of global capitalism and global movement. Conclusion In seeking to explain the popularity and supply of alternative health care, it is important to go beyond the culture of each kind of health care itself and to take into consideration the changes occurring at societal, national and global levels as well as consequential individual response to the changes. New social conditions influence the choice of health care methods, including herbal/alternative medicine, health foods and what are often called New Age therapies.

  12. The mismatch of bioaccumulated trace metals (Cu, Pb and Zn) in field and transplanted oysters (Saccostrea glomerata) to ambient surficial sediments and suspended particulate matter in a highly urbanised estuary (Sydney estuary, Australia). (United States)

    Lee, Jung-Ho; Birch, Gavin F


    A significant correlation between sedimentary metals, particularly the 'bio-available' fraction, and bioaccumulated metal concentrations in the native Sydney rock oyster (Saccostrea glomerata) tissues has been successfully demonstrated previously for Cu and Zn in a number of estuaries in New South Wales, Australia. However, this relationship has been difficult to establish in a highly modified estuary (Sydney estuary, Australia) where metal contamination is of greatest concern and where a significant relationship would be most useful for environmental monitoring. The use of the Sydney rock oyster as a biomonitoring tool for metal contamination was assessed in the present study by investigating relationships between metals attached to sediments and suspended particulate matter (SPM) to bioaccumulated concentrations in oyster tissues. Surficial sediments (both total and fine-fraction), SPM and wild oysters were collected over 3 years from three embayments (Chowder Bay, Mosman Bay and Iron Cove) with each embayment representing a different physiographic region of Sydney estuary. In addition, a transplant experiment of farmed oysters was conducted in the same embayments for 3 months. No relationship was observed between sediments or SPM metals (Cu, Pb and Zn) to tissue of wild oysters; however, significant relationship was observed against transplanted oysters. The mismatch between wild and farmed, transplanted oysters is perplexing and indicates that wild oysters are unsuitable to be used as a biomonitoring tool due to the involvement of unknown complex factors while transplanted oysters hold strong potential.

  13. Immigrant maternal depression and social networks. A multilevel Bayesian spatial logistic regression in South Western Sydney, Australia. (United States)

    Eastwood, John G; Jalaludin, Bin B; Kemp, Lynn A; Phung, Hai N; Barnett, Bryanne E W


    The purpose is to explore the multilevel spatial distribution of depressive symptoms among migrant mothers in South Western Sydney and to identify any group level associations that could inform subsequent theory building and local public health interventions. Migrant mothers (n=7256) delivering in 2002 and 2003 were assessed at 2-3 weeks after delivery for risk factors for depressive symptoms. The binary outcome variables were Edinburgh Postnatal Depression Scale scores (EPDS) of >9 and >12. Individual level variables included were: financial income, self-reported maternal health, social support network, emotional support, practical support, baby trouble sleeping, baby demanding and baby not content. The group level variable reported here is aggregated social support networks. We used Bayesian hierarchical multilevel spatial modelling with conditional autoregression. Migrant mothers were at higher risk of having depressive symptoms if they lived in a community with predominantly Australian-born mothers and strong social capital as measured by aggregated social networks. These findings suggest that migrant mothers are socially isolated and current home visiting services should be strengthened for migrant mothers living in communities where they may have poor social networks.

  14. Development of an estuarine assessment scheme for the management of a highly urbanised catchment/estuary system, Sydney estuary, Australia. (United States)

    Birch, G F; Gunns, T J; Chapman, D; Harrison, D


    As coastal populations increase, considerable pressures are exerted on estuarine environments. Recently, there has been a trend towards the development and use of estuarine assessment schemes as a decision support tool in the management of these environments. These schemes offer a method by which complex environmental data is converted into a readily understandable and communicable format for informed decision making and effective distribution of limited management resources. Reliability and effectiveness of these schemes are often limited due to a complex assessment framework, poor data management and use of ineffective environmental indicators. The current scheme aims to improve reliability in the reporting of estuarine condition by including a concise assessment framework, employing high-value indicators and, in a unique approach, employing fuzzy logic in indicator evaluation. Using Sydney estuary as a case study, each of the 15 sub-catchment/sub-estuary systems were assessed using the current scheme. Results identified that poor sediment quality was a significant issue in Blackwattle/Rozelle Bay, Iron Cove and Hen and Chicken Bay while poor water quality was of particular concern in Duck River, Homebush Bay and the Parramatta River. Overall results of the assessment scheme were used to prioritise the management of each sub-catchment/sub-estuary assessed with Blackwattle/Rozelle Bay, Homebush Bay, Iron Cove and Duck River considered to be in need of a high priority management response. A report card format, using letter grades, was employed to convey the results of the assessment in a readily understood manner to estuarine managers and members of the public. Letter grades also provide benchmarking and performance monitoring ability, allowing estuarine managers to set improvement targets and assesses the effectiveness of management strategies. The current assessment scheme provides an effective, integrated and consistent assessment of estuarine health and

    F. Dall'Osso


    Full Text Available Australia is at risk from tsunamis and recent work has identified the need for models to assess the vulnerability of exposed coastal areas – a fundamental element of the risk management process. Outputs of vulnerability assessment can be used as a baseline for the generation of tsunami prevention and mitigation measures, including evacuation maps. Having noted that no evacuation maps exist for Manly, Sydney (an area recently subjected to high resolution building vulnerability assessment by Dall'Osso et al., 2009b, we use the results of the analysis by Dall'Osso et al. (2009b to "draft" tsunami evacuation maps that could be used by the local emergency service organisations. We then interviewed 500 permanent residents of Manly in order to gain a rapid assessment on their views about the potential usefulness of the draft evacuation maps we generated. Results of the survey indicate that residents think the maps are useful and understandable, and include insights that should be considered by local government planners and emergency risk management specialists during the development of official evacuation maps (and plans in the future.

  16. Is there a role for workplaces in reducing employees' driving to work? Findings from a cross-sectional survey from inner-west Sydney, Australia

    Full Text Available Abstract Background The role of workplaces in promoting active travel (walking, cycling or using public transport is relatively unexplored. This study explores the potential for workplaces to reduce employees' driving to work in order to inform the development of workplace interventions for promoting active travel. Methods An analysis of a cross-sectional survey was conducted using data from parents/guardians whose children participated in the Central Sydney Walk to School Program in inner-west Sydney, Australia. A total of 888 parents/guardians who were employed and worked outside home were included in this analysis. The role of the workplace in regards to active travel was assessed by asking the respondents' level of agreement to eight statements including workplace encouragement of active travel, flexible working hours, public transport availability, convenient parking, shower and change rooms for employees and whether they lived or worked in a safe place. Self-reported main mode of journey to work and demographic data were collected through a self-administrated survey. Binary logistic regression modelling was used to ascertain independent predictors of driving to work. Results Sixty nine per cent of respondents travelled to work by car, and 19% agreed with the statement, "My workplace encourages its employees to go to and from work by public transport, cycling and/or walking (active travel." The survey respondents with a workplace encouraging active travel to work were significantly less likely to drive to work (49% than those without this encouragement (73% with an adjusted odds ratio (AOR of 0.41 (95% CI 0.23-0.73, P = 0.002. Having convenient public transport close to the workplace or home was also an important factor that could discourage employees from driving to work with AOR 0.17 (95% CI 0.09-0.31, P Conclusions There is a significant inverse association between the perception of workplace encouragement for active travel and driving

  17. Experiences in managing problematic crystal methamphetamine use and associated depression in gay men and HIV positive men: in-depth interviews with general practitioners in Sydney, Australia. (United States)

    Saltman, Deborah C; Newman, Christy E; Mao, Limin; Kippax, Susan C; Kidd, Michael R


    This paper describes the experiences of Australian general practitioners (GPs) in managing problematic crystal methamphetamine (crystal meth) use among two groups of male patients: gay men and HIV positive men. Semi-structured qualitative interviews with GPs with HIV medication prescribing rights were conducted in Sydney, Adelaide and a rural-coastal town in New South Wales between August and October 2006. Participants were recruited from practices with high caseloads of gay and HIV positive men. Sixteen GPs were recruited from seven practices to take part in interviews. Participants included 14 male GPs and two female GPs, and the number of years each had been working in HIV medicine ranged from two to 24. Eleven of the GPs who were based in Sydney raised the issue of problematic crystal meth use in these two patient populations. Five key themes were identified: an increasing problem; associations with depression; treatment challenges; health services and health care; workforce issues. Despite study limitations, key implications can be identified. Health practitioners may benefit from broadening their understandings of how to anticipate and respond to problematic levels of crystal meth use in their patients. Early intervention can mitigate the impact of crystal meth use on co-morbid mental illness and other health issues. Management of the complex relationships between drug use, depression, sexuality and HIV can be addressed following a 'stepped care' approach. General practice guidelines for the management of crystal meth use problems should address specific issues associated with gay men and HIV positive men. GPs and other health practitioners must appreciate drug use as a social practice in order to build trust with gay men to encourage full disclosure of drug use. Education programs should train health practitioners in these issues, and increased resourcing provided to support the often difficult task of caring for people who use crystal meth. Greater

  18. Adequacy of nutritional intake among older men living in Sydney, Australia: findings from the Concord Health and Ageing in Men Project (CHAMP). (United States)

    Waern, Rosilene V R; Cumming, Robert G; Blyth, Fiona; Naganathan, Vasi; Allman-Farinelli, Margaret; Le Couteur, David; Simpson, Stephen J; Kendig, Hal; Hirani, Vasant


    Previous research shows that older men tend to have lower nutritional intakes and higher risk of under-nutrition compared with younger men. The objectives of this study were to describe energy and nutrient intakes, assess nutritional risk and investigate factors associated with poor intake of energy and key nutrients in community-dwelling men aged ≥75 years participating in the Concord Health and Ageing in Men Project - a longitudinal cohort study on older men in Sydney, Australia. A total of 794 men (mean age 81·4 years) had a detailed diet history interview, which was carried out by a dietitian. Dietary adequacy was assessed by comparing median intakes with nutrient reference values (NRV): estimated average requirement, adequate intake or upper level of intake. Attainment of NRV of total energy and key nutrients in older age (protein, Fe, Zn, riboflavin, Ca and vitamin D) was incorporated into a 'key nutrients' variable dichotomised as 'good' (≥5) or 'poor' (≤4). Using logistic regression modelling, we examined associations between key nutrients with factors known to affect food intake. Median energy intake was 8728 kJ (P5=5762 kJ, P95=12 303 kJ), and mean BMI was 27·7 (sd 4·0) kg/m2. Men met their NRV for most nutrients. However, only 1 % of men met their NRV for vitamin D, only 19 % for Ca, only 30 % for K and only 33 % for dietary fibre. Multivariate logistic regression analysis showed that only country of birth was significantly associated with poor nutritional intake. Dietary intakes were adequate for most nutrients; however, only half of the participants met the NRV of ≥5 key nutrients.

  19. Polycyclic aromatic hydrocarbons in road-deposited sediments, water sediments, and soils in Sydney, Australia: Comparisons of concentration distribution, sources and potential toxicity. (United States)

    Nguyen, Thuy Chung; Loganathan, Paripurnanda; Nguyen, Tien Vinh; Vigneswaran, Saravanamuthu; Kandasamy, Jaya; Slee, Danny; Stevenson, Gavin; Naidu, Ravi


    Sixteen polycyclic aromatic hydrocarbons (PAHs) considered as priority environmental pollutants were analysed in surface natural soils (NS), road-deposited sediments (RDS), and water sediments (WS) at Kogarah in Sydney, Australia. Comparisons were made of their concentration distributions, likely sources and potential toxicities. The concentrations (mg/kg) in NS, RDS, and WS ranged from 0.40 to 7.49 (mean 2.80), 1.65 to 4.00 (mean 2.91), and 0.49 to 5.19 (mean 1.76), respectively. PAHs were dominated by relatively high molecular weight compounds with more than three fused benzene rings, indicating that high temperature combustion processes were their predominant sources. The proportions of high molecular weight PAHs with five or six fused benzene rings were higher in NS than in RDS, whereas the low molecular weight PAHs were higher in RDS. Concentrations of all PAHs compounds were observed to be the lowest in WS. The concentrations of most of the high molecular weight PAHs significantly correlated with each other in RDS and WS. All PAHs (except naphthalene) were significantly correlated in NS suggesting a common PAH source. Ratios for individual diagnostic PAHs demonstrated that the primary source of PAHs in WS and NS was of pyrogenic origin (combustion of petroleum (vehicle exhaust), grass, and wood) while in RDS it was petrogenic (i.e. unburned or leaked fuel and oil, road asphalt, and tyre particles) as well as pyrogenic. The potential toxicities of PAHs calculated using a toxicity equivalent quotient (TEQ) were all low but higher for NS compared to WS and RDS.

  1. On-site wastewater technologies in Australia. (United States)

    Ho, G; Dallas, S; Anda, M; Mathew, K


    Domestic wastewater reuse is currently not permitted anywhere in Australia but is widely supported by the community, promoted by researchers, and improvised by up to 20% of householders. Its widespread implementation will make an enormous contribution to the sustainability of water resources. Integrated with other strategies in the outdoor living environment of settlements in arid lands, great benefit will be derived. This paper describes six options for wastewater reuse under research by the Remote Area Developments Group (RADG) at Murdoch University and case studies are given where productive use is being made for revegetation and food production strategies at household and community scales. Pollution control techniques, public health precautions and maintenance requirements are described. The special case of remote Aboriginal communities is explained where prototype systems have been installed by RADG to generate windbreaks and orchards. New Australian design standards and draft guidelines for domestic greywater reuse produced by the Western Australian State government agencies for mainstream communities are evaluated. It is recommended that dry composting toilets be coupled with domestic greywater reuse and the various types available in Australia are described. For situations where only the flushing toilet will suffice the unique 'wet composting' system can be used and this also is described. A vision for household and community-scale on-site application is presented.

  2. Use of and short-term impacts of new cycling infrastructure in inner-Sydney, Australia: a quasi-experimental design. (United States)

    Rissel, Chris; Greaves, Stephen; Wen, Li Ming; Crane, Melanie; Standen, Chris


    Given increasing investment in new cycling infrastructure, it is important to understand its impacts. The Sydney Transport and Health Study evaluates a new 2.4 km bi-directional separated bicycle path in inner-Sydney. This paper describes the users of the new bicycle path, and examines its short-term impacts upon cycling behaviour and perceptions of the local environment. Data were collected from two bike counts at two intersections on the new bicycle path in the intervention area in 2013 and 2014. On-line surveys collected individual participant data in the intervention area and a similar comparison area before the bicycle path was built (2013), and 12 months later (four months after completion) (n = 512). The data included self-reported cycling behaviour, use of the new bicycle path and perceptions of changes in the local environment. Bike counts at two sites on the new bicycle path reported an increase of 23% and 97% respectively at 12 months. However, among the participants in the cohort, there was no change in the self-reported weekly frequency of cycling. One in six (approximately 15%) participants reported using the new bicycle path, with most users (76%) living in the intervention area. Bicycle path users were most likely to be frequent riders (at least weekly) [adjusted odds ratio (AOR) = 7.50, 95 % CI 3.93-14.31], be a high intensity recreational rider (AOR = 4.38, 95 % CI 1.53-12.54) or a low intensity transport rider (AOR = 2.42, 95 % CI 1.17-5.04) and live closer to the bicycle path (AOR = 1.24, 1.13-1.37). Perceptions that the neighbourhood was more pleasant, that there were more people walking and cycling were significantly higher in the intervention area at 12 months (both P values <0.05). Existing cycling behaviour and proximity to the bicycle path were associated with the use of the new bicycle path. Increased use of the new bicycle path as reported by the participants in the intervention area and increased cycling recorded by

    Eastwood, John Graeme; Kemp, Lynn Ann; Jalaludin, Bin Badrudin; Phung, Hai Ngoc


    The aim of the study reported here is to explore ecological covariate and latent variable associations with perinatal depressive symptoms in South Western Sydney for the purpose of informing subsequent theory generation of perinatal context, depression, and the developmental origins of health and disease. Mothers (n = 15,389) delivering in 2002 and 2003 were assessed at two to three weeks after delivery for risk factors for depressive symptoms. The binary outcome variables were Edinburgh Postnatal Depression Scale (EPDS)> 9 and > 12. Aggregated EPDS > 9 was analyzed for 101 suburbs. Suburb-level variables were drawn from the 2001 Australian Census, New South Wales Crime Statistics, and aggregated individual-level risk factors. Analysis included exploratory factor analysis, univariate and multivariate likelihood, and Bayesian linear regression with conditional autoregressive components. The exploratory factor analysis identified six factors: neighborhood adversity, social cohesion, health behaviors, housing quality, social services, and support networks. Variables associated with neighborhood adversity, social cohesion, social networks, and ethnic diversity were consistently associated with aggregated depressive symptoms. The findings support the theoretical proposition that neighborhood adversity causes maternal psychological distress and depression within the context of social buffers including social networks, social cohesion, and social services.

  6. Young people at risk of transitioning to injecting drug use in Sydney, Australia: social disadvantage and other correlates of higher levels of exposure to injecting. (United States)

    Lea, Toby; Bryant, Joanne; Ellard, Jeanne; Howard, John; Treloar, Carla


    While numerous studies have examined characteristics of young people who have recently initiated injecting, little attention has focused on young people who may be at high risk of transitioning to injecting. This study sought to examine the extent that socially disadvantaged young people were exposed to injecting, determine their level of hepatitis C (HCV) knowledge and identify correlates of higher injecting exposure. A cross-sectional survey was administered to 210 young people in 2010-2011 who were exposed to injecting drug use, but had not transitioned to injecting. Respondents were primarily recruited from youth services in metropolitan Sydney. Exposure to injecting in the previous 12 months was assessed with four items that examined whether close friends, romantic/sexual partners or family members/acquaintances injected drugs, and whether they were offered an injection. Most respondents had at least a few close friends who injected drugs (65%) and almost half had been offered drugs to inject in the previous 12 months (48%). It was less common for respondents to report having a partner who injects (11%). Correlates of higher injecting exposure were examined with multivariate ordinal regression. In the multivariate model, higher exposure to injecting was independently associated with the experience of abuse or violent crime [adjusted odds ratio (AOR) = 1.80] and reporting more favourable attitudes towards injecting (AOR = 0.86). Higher exposure to injecting was not independently associated with patterns or history of drug use. HCV knowledge was low to moderate and was not associated with higher exposure to injecting. That drug use was not independently associated with higher injecting exposure may suggest that exposure is shaped more by social disadvantage than by drug use patterns. Additional research is required to investigate this, using an improved measure of exposure to injecting. © 2014 John Wiley & Sons Ltd.

  7. Dietary vitamin, mineral and herbal supplement use: a cross-sectional survey of before and during pregnancy use in Sydney, Australia. (United States)

    Shand, Antonia W; Walls, Mariyam; Chatterjee, Rahul; Nassar, Natasha; Khambalia, Amina Z


    To describe the use of dietary vitamin, mineral and herbal supplements before and during pregnancy. Pregnant women attending for antenatal care at two tertiary Sydney hospitals between January and March 2014 completed an anonymous survey. Information on general maternal and pregnancy characteristics and the use of dietary and herbal supplements, including type, duration and sources of information, was collected. Frequency and contingency tabulations were performed. A total of 612 women agreed to participate (91% response rate). Of 589 women included in the analysis, mean gestational age at the time of survey was 28.5 weeks (SD 8.3), 55% had no children, and 67% were tertiary-educated. Overall, 62.9% of women reported taking a multivitamin (MV) and/or folic acid (FA) supplement in the 3 months prepregnancy, and 97.5% took a MV and/or FA in the first trimester. At the time of the survey, 93.8% of women were taking at least one supplement (median 2, range 1-13). During pregnancy, 79.1% of women were taking MVs, including 59.2% taking MV only and 19.9% taking MV and FA. The five most common supplements outside of a MV were FA (31%), iron (30%), vitamin D (23%), calcium (13%) and fish oil (12%). Reported herbal supplement rates were low. Folic acid, MVs and other supplements use during and prepregnancy is relatively high, although prepregnancy FA supplementation rates could still be improved. Further research on the actual dosages and dietary intakes consumed is needed to examine whether pregnant women have adequate intake of nutrients, regardless of supplement use. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Full Text Available Abstract Background Time spent outdoors is positively associated with physical activity and has been suggested as a proxy for physical activity of children. The role of children's independence in physical activity and time spent outdoors is less understood. This study aimed to assess how much time children spent playing outdoors after school, and to explore the relationship between outdoor play and independence among children aged 10–12 years. Method Children recorded how much time they spent playing outdoors or watching TV/videos or playing computer games after school using a five-day diary, and also reported whether they were allowed to walk on their own in their neighbourhood as an indicator of their independent mobility. Parents were surveyed on family demographics and perception of neighbourhood safety. The surveys were conducted in late 2006 as part of the Central Sydney Walk to School program which involved 1975 children and their parents from 24 primary schools. Factors associated with time spent playing outdoors were determined by logistic regression modelling. Results Thirty-seven per cent of children spent less than half an hour a day playing outdoors after school, and 43% spent more than 2 hours a day watching TV, videos or playing computer games. Forty-eight per cent of children were allowed to walk on their own near where they lived. Children's independent mobility was significantly associated with outdoor play after adjusting for other confounders. Compared with those who were never allowed to walk on their own near where they lived, students who were allowed to walk on their own were significantly more likely to spend more than half an hour a day playing outdoors after school with an adjusted odds ratio of 2.6, 95% CI 1.84–3.58, P Conclusion The findings that a significant proportion of children spend less than half an hour a day playing outdoors after school and have excessive screen time have important implications for

    The large dependence of Australia on the fossil fuels leads to an great emission of carbon dioxide. The Australia is thus the first greenhouse gases emitter per habitant, in the world. In spite of its sufficient fossil fuels reserves, the Australia increases its production of clean energies and the research programs in the domain of the new energies technology. After a presentation of the australia situation, the authors detail the government measures in favor of the new energy technologies and the situation of the hydroelectricity, the wind energy, the wave and tidal energy, the biomass, the biofuels, the solar energy, the ''clean'' coal, the hydrogen and the geothermal energy.

    Anal cytology has been suggested as a screening test for the anal cancer precursor high-grade squamous intraepithelial lesion (HSIL). We aimed to assess the prevalence and predictors of initial unsatisfactory anal cytology tests ('unsats'). The Study of the Prevention of Anal Cancer is a natural history study of anal human papillomavirus (HPV) and precancerous lesions among gay and bisexual men (GBM) of at least 35 years in Sydney, Australia. At each study visit, an anal swab is collected for cytological testing. Unsats are defined as slides with fewer than 2000 nucleated squamous cells and no abnormal cells. Among 617 GBM enrolled, the median age was 49 (range: 35-79) years and 220 (35.7%) were HIV positive. Initial unsats occurred in 61 (9.9%, 95% confidence interval: 7.6-12.5%), and 29 (4.7%, 95% confidence interval: 3.2-6.7%) remained unsatisfactory on repeat cytology. Initial unsats were associated with fewer lifetime anal-receptive partners with a condom (P=0.007); fewer recent anal-receptive sexual partners without a condom (P=0.005); never having had anal chlamydia (P=0.023) or gonorrhea (P=0.003); HIV-negative status (P=0.002); fewer total (P=0.002), low-risk (P=0.005), and high-risk (P=0.015) HPV types detected; lack of anal HPV18 detection (P=0.001); never having anally douched (Panal canal octants affected by HSIL (P=0.080), but were more common among those who felt more nervous (P=0.020) during the examination. Our findings suggest that unsats are more common among GBM with less receptive anal sexual experience. Avoiding douching with soapy water and strategies to aid patient relaxation during sampling may reduce the unsat rate.

  11. Assistive Technology in Australia: Integrating theory and evidence into action. (United States)

    Steel, Emily J; Layton, Natasha A


    Occupational therapists use a range of strategies to influence the relationship between person, environment and occupation and facilitate people's participation and inclusion in society. Technology is a fundamental environmental factor capable of enabling inclusion, and occupational therapy models articulate a role for assistive technology (AT) devices and services, but there is a gap between theory, research and practice. The context of AT provision in Australia presents systemic barriers that prevent optimal application of AT devices and services for societal health promotion and in individualised solutions. The Integrating Theory, Evidence and Action method (ITEA) was used to answer the question 'How can occupational therapy support AT provision to enable older people and people with disability?' A wide range of sources were systematically analysed to explore the complexities of AT provision in Australia. The International Classification of Functioning, Disability and Health (ICF) and IMPACT(2) model are used as frameworks to reconstruct evidence into statements that summarise the theory, process and outcomes of AT provision. Analysis of the influence of the global disability rights and local policies and AT provision systems is used to highlight important aspects for occupational therapists to consider in research and practice. Pragmatic recommendations are provided to enable practitioners to translate theory and evidence into action. AT provision can be improved by focusing on evidence for and congruence between theory, process and outcomes, rather than isolated interventions. Occupational therapists should consider the influence of contextual factors on practice, and work with consumers to improve access and equity in AT provision systems. © 2016 Occupational Therapy Australia.

    Background HIV diagnoses have been increasing steadily in Australia and are concentrated among gay, bisexual and other men who have sex with men (GBM). HIV testing is a key control strategy, and in 2013, a novel time-limited pop-up community HIV testing service (Pop-up) was introduced to raise awareness and increase testing options for GBM. The Pop-up service offered rapid HIV tests only. We compared uptake and outcomes of the Pop-up service to an established clinical model [a fast-track screening service in a sexual health clinic offering rapid and/or conventional HIV tests and sexually transmissible infection (STI) tests]. Service delivery data was collated and analysed from the HIV Pop-up (25 November to 1 December 2013) and the fast-track HIV/STI screening service (Xpress) in a sexual health clinic immediately before the Pop-up (1 August to 22 November 2013). A comparison of all the HIV tests and results, tests per hour and characteristics of new clients (demographics, risk behaviour, testing history) was conducted using χ(2), Poisson distribution and Ranksum tests. At the Pop-up service, 182 GBM had a rapid HIV test conducted over the 5-day period (average: seven HIV tests per hour) and no HIV tests were reactive (0%, 95% confidence interval: 0-1.8%). At the Xpress service, 1075 asymptomatic GBM had at least one STI test and 957 GMB had a HIV test (rapid or conventional) conducted over the 3-month period (average: four HIV tests per hour), with two positive HIV tests (0.2%, 95% confidence interval: 0.02-0.7) and 151 positive STI tests (14%, 95% confidence interval: 12-16.2). Compared with new patients at the Xpress service, GBM attending the Pop-up service were older (median of 39 vs 29 years, PPop-up community HIV testing is feasible and reached high-risk GBM, but compared with a clinic-based model, it only reached a smaller proportion of GBM who test infrequently or who have never been tested and are unaware of their HIV status. No STI testing was conducted

  13. Assistive technology pricing in Australia: is it efficient and equitable? (United States)

    Summers, Michael P; Verikios, George


    Objective To examine available systematically collected evidence regarding prices for assistive technology (AT; e.g. disability aids and equipment) in Australia with other comparable countries. Issues of appropriate AT pricing are coming to the fore as a consequence of efforts to move to consumer-centric purchasing decisions with the National Disability Insurance Scheme (NDIS) and also in the recent aged care reforms.Methods We identified and present three sets of AT price comparisons. Two comparisons were based solely on the lowest prices advertised on the internet, and one comparison examined recommended retail prices. Variables essential to ensuring accurate comparisons, as well as significant supply-chain issues were also examined and considered in the analyses.Results The first internet-only price comparison found that overall AT prices were 38% higher in Australia compared to other countries, but did not factor in shipping and other related costs that are essential to include given that most AT is imported. The second internet-only price comparison found that overall Australian prices were 24% lower when shipping and related costs were included. The recommended retail price comparisons found that Australian prices were between 14% and 27% lower. Prices for internet-only retailers (those with no bricks-and-mortar presence) are consistently lower for all products than those sold by retailers with actual shop-fronts. Further, there is no evidence of suppliers earning supranormal profits in Australia.Conclusions The results indicate that AT prices in Australia are efficient and equitable, with no significant indicators of market failure which would require government intervention. Efforts to reduce prices through the excessive use of large-scale government procurement programs are likely to reduce diversity and innovation in AT and raise AT prices over time. Open markets and competition with centralised tracking of purchases and providers to minimise possible

  14. Australia. (United States)


    The smallest continent and one of the largest countries, Australia is a country of diverse geographical conditions and differing cultures of people unified by one predominant language and political system. Mountains, desert and rivers are some of the varying landscape features of Australia, although the climate and condition for most of the country is tropical. Original Australians, a hunting-gathering people called Aborigines, came to Australia over 38,000 years ago. Today the Aborigines compose about 1% of the population and live in traditional tribal areas as well as cities. The 1st European settlement came in 1788 from Great Britain. After World War II, the population doubled. Although the population is primarily composed of British and Irish immigrants, immigrants from other European countries such as Italy and Greece as well as refugees from Indochina, Vietnam, Cambodia and Laos are a significant factor to the growing Australian population. Australian and Aboriginal culture has took hold and took notice in the areas of opera, art, literature and film. The Australian Commonwealth is based on a constitution similar to that of the United States government. The National Parliament is bicameral with both the Senate and the House of Representatives having a select number of elected officials from each state and territory. The Australian economy is predominantly reliant on the sale of mineral and agricultural exports. History, economic changes, defense, international relations and notes to the traveler are also discussed in this overview of Australia.

  17. Health technology assessment in Australia: a role for clinical registries? (United States)

    Scott, Anna Mae


    Objective Health technology assessment (HTA) is a process of assessing evidence to inform policy decisions about public subsidy of new drugs and medical procedures. Where evidence is uncertain but the technology itself is promising, funders may recommend funding on an interim basis. It is unknown whether evidence from clinical registries is used to resolve uncertainties identified in interim-funded decisions made by Australian HTA bodies. Therefore, the present study evaluated the role of evidence from clinical registries in resolving evidence uncertainties identified by the Medical Services Advisory Committee (MSAC).Methods All HTAs considered by MSAC between 1998 and 2015 were reviewed and assessments that recommended interim funding were identified. The MSAC website was searched to identify reassessments of these recommendations and sources of evidence used to resolve the uncertainties were identified.Results Of 173 HTA reports considered by MSAC, 17 (10%) contained an interim funding recommendation. Eight recommendations cited uncertainty around safety, 15 cited uncertainty around clinical effectiveness and 13 cited uncertainty around economics (cost-effectiveness and/or budget impact). Of the 17 interim funding recommendations, 11 (65%) have been reassessed. Only two reassessments relied on clinical registry evidence to resolve evidence gaps identified at the time of the interim funding recommendation.Conclusions Clinical registries are underused as a source of evidence for resolving uncertainties around promising new health technologies in Australia. An open dialogue between stakeholders on the role of registries in this context is needed.What is known about the topic? HTA is a process of assessing the evidence to inform policy decisions about public subsidy of new health technologies (e.g. pharmaceuticals, diagnostic tests, medical procedures). Where evidence is uncertain but the technology under evaluation is promising, funders may recommend the funding of

  4. Vicious cycles: digital technologies and determinants of health in Australia. (United States)

    Baum, Fran; Newman, Lareen; Biedrzycki, Katherine


    Digital technologies are increasingly important as ways to gain access to most of the important social determinants of health including employment, housing, education and social networks. However, little is known about the impact of the new technologies on opportunities for health and well-being. This paper reports on a focus group study of the impact of these technologies on people from low socio-economic backgrounds. We use Bourdieu's theories of social inequities and the ways in which social, cultural and economic capitals interact to reinforce and reproduce inequities to examine the ways in which digital technologies are contributing to these processes. Six focus group discussions with 55 people were held to examine their access to and views about using digital technologies. These data are analysed in light of Bourdieu's theory to determine how people's existing capitals shape their access to and use of digital technologies and what the implications of exclusion from the technologies are likely to be for the social determinants of health. The paper concludes that some people are being caught in a vicious cycle whereby lack of digital access or the inability to make beneficial use reinforces and amplifies existing disadvantage including low levels of reading and writing literacy. The paper concludes with a consideration of actions health promoters could take to interrupt this cycle and so contribute to reducing health inequities.

  5. DJ Culture in the Commercial Sydney Dance Music Scene

    Directory of Open Access Journals (Sweden)

    Ed Montano


    Full Text Available The development of contemporary, post-disco dance music and its associated culture, as representative of a (supposedly underground, radical subculture, has been given extensive consideration within popular music studies. Significantly less attention has been given to the commercial, mainstream manifestations of this music. Therefore, this article examines the contemporary commercial dance music scene in Sydney, Australia, incorporating an analytical framework that revolves mainly around the work of DJs and the commercial scene they operate within. The ideas, opinions and interpretations of a selection of local DJs and other music industry practitioners who work in Sydney are central to the article’s analysis of DJ culture within the city and of, more specifically, DJ self-understandings with respect to choices of records and in relation to the twin imperatives of entertainment and education.

  6. Accessibility to general practitioners in rural South Australia. A case study using geographic information system technology. (United States)

    Bamford, E J; Dunne, L; Taylor, D S; Symon, B G; Hugo, G J; Wilkinson, D

    To demonstrate the potential of GIS (geographic information system) technology and ARIA (Accessibility/Remoteness Index for Australia) as tools for medical workforce and health service planning in Australia. ARIA is an index of remoteness derived by measuring road distance between populated localities and service centres. A continuous variable of remoteness from 0 to 12 is generated for any location in Australia. We created a GIS, with data on location of general practitioner services in non-metropolitan South Australia derived from the database of RUMPS (Rural Undergraduate Medical Placement System), and estimated, for the 1170 populated localities in South Australia, the accessibility/inaccessibility of the 109 identified GP services. Distance from populated locality to GP services. Distance from populated locality to GP service ranged from 0 to 677 km (mean, 58 km). In all, 513 localities (43%) had a GP service within 20 km (for the majority this meant located within the town). However, for 173 populated localities (15%), the nearest GP service was more than 80 km away. There was a strong correlation between distance to GP service and ARIA value for each locality (0.69; P planning. Adding measures of health need and more detailed data on types and extent of GP services provided will allow more sophisticated planning.

  9. Exploring the consistency, transparency and portability of dental technology education: benchmarking across Norway, Ireland and Australia. (United States)

    Myhrer, T; Evans, J L; Haugen, H K; Gorman, C; Kavanagh, Y; Cameron, A B


    Dental technology programmes of study must prepare students to practice in a broad range of contemporary workplaces. Currently, there is limited evidence to benchmark dental technology education - locally, nationally or internationally. This research aims to improve consistency, transparency and portability of dental technology qualifications across three countries. Data were accessed from open-source curriculum documents and five calibrated assessment items. Three institutions collaborated with Oslo and Akershus University College, Norway; Trinity College Dublin, Ireland; and Griffith University, Australia. From these, 29-44 students completed 174 assessments. The curricula reflect the community needs of each country and display common themes that underpin professional dental technology practice. Assessment results differed between institutions but no more than a normal distribution. Face-to-face assessment moderation was critical to achieve consistency. This collaborative research has led to the development of a set of guidelines for other dental technology education providers interested in developing or aligning courses internationally to enhance the portability of qualifications.

  11. Hailstones across the Greater Sydney Metropolitan Area

    Directory of Open Access Journals (Sweden)

    A. A. Rasuly


    Full Text Available This study addresses the recent climatology of hail occurrence in the Greater Metropolitan Severe Thunderstorm Warning Area (GMSTWA of New South Wales, Australia, which is a sprawling suburban area, with a population of nearly 4.7 million and one of Australia's largest metropolis. The main objective is to highlight the recent temporal-spatial fluctuations of hailstone frequencies and magnitudes for each of recognized and vastly inhabited Local Government Areas (LGAs. The relevant hail event data from 1989 to 2013 were initially derived from the severe storm archive of Australian Bureau of Meteorology. A climatologically oriented GIS technique was applied in the examining and mapping procedure of all hail events and hail days reported throughout the study area. By applying a specific criterion, all severe hails (defined as 2 cm or more in diameter were cautiously selected and then imported into the ArcGIS software for relevant analysis. Appropriate data layers were stored in a unique database to allow logical integration of the data directly into some geoprocessing functions, mainly for querying, analyzing and mapping purposes in a model-builder setting. The database includes 357 hailstones with sizes 2–11 cm and occurred in 169 hail days across the region during the past 25 years. The models have established that hailstones are neither temporally nor spatially uniform in magnitude throughout the study area. Temporal analysis indicated that most of hail events occurred predominately in the afternoons with peak time of 1–5 p.m. EST. They were particularly common in spring and summer, and reached maximum frequency in November and December. There was an average of 14.3 events each year, but a significant decreasing trend in terms of hail frequency and associated magnitude in the recent years has been identified. In turn, spatial models also established three main distribution patterns over the study area, which include the Sydney Metropolitan

  12. Challenges of user-centred assistive technology provision in Australia: shopping without a prescription. (United States)

    Steel, Emily J; Layton, Natasha Ann; Foster, Michele M; Bennett, Sally


    People with disability have a right to assistive technology devices and services, to support their inclusion and participation in society. User-centred approaches aim to address consumer dissatisfaction and sub-optimal outcomes from assistive technology (AT) provision, but make assumptions of consumer literacy and empowerment. Policy discourses about consumer choice prompt careful reflection, and this paper aims to provide a critical perspective on user involvement in assistive technology provision. User-centred approaches are considered, using literature to critically reflect on what user involvement means in AT provision. Challenges at the level of interactions between practitioners and consumers, and also the level of markets and policies are discussed, using examples from Australia. There is no unanimous conceptual framework for user-centred practice. Power imbalances and differing perspectives between practitioners and consumers make it difficult for consumers to feel empowered. Online access to information and international suppliers has not surmounted information asymmetries for consumers or lifted the regulation of publicly funded AT devices. Ensuring access and equity in the public provision of AT is challenging in an expanding market with diverse stakeholders. Consumers require personalised information and support to facilitate their involvement and choice in AT provision. Implications for Rehabilitation Variations in approaches informing AT provision practices have a profound impact on equity of access and outcomes for consumers. An internationalised and online market for AT devices is increasing the need for effective information provision strategies and services. Power imbalances between practitioners and consumers present barriers to the realisation of user-centred practice.

  13. Media debates and 'ethical publicity' on social sex selection through preimplantation genetic diagnosis (PGD) technology in Australia. (United States)

    Whittaker, Andrea


    This paper offers a critical discourse analysis of media debate over social sex selection in the Australian media from 2008 to 2014. This period coincides with a review of the National Health and Medical Research Council's Ethical Guidelines on the Use of Assisted Reproductive Technology in Clinical Practice and Research (2007), which underlie the regulation of assisted reproductive clinics and practice in Australia. I examine the discussion of the ethics of pre-implatation genetic diagnosis (PGD) within the media as 'ethical publicity' to the lay public. Sex selection through PGD is both exemplary of and interconnected with a range of debates in Australia about the legitimacy of certain reproductive choices and the extent to which procreative liberties should be restricted. Major themes emerging from media reports on PGD sex selection in Australia are described. These include: the spectre of science out of control; ramifications for the contestation over the public funding of abortion in Australia; private choices versus public authorities regulating reproduction; and the ethics of travelling overseas for the technology. It is concluded that within Australia, the issue of PGD sex selection is framed in terms of questions of individual freedom against the principle of sex discrimination - a principle enshrined in legislation - and a commitment to publically-funded medical care.

  15. The great Sydney dust event: Size-resolved chemical composition and comparison (United States)

    Box, Michael A.; Radhi, Majed; Box, Gail P.


    In September 2009, a major dust storm crossed eastern Australia, blanketing Sydney on two occasions. We collected size-resolved aerosol samples on both days, and have subjected them to Ion Beam Analysis at ANSTO. In this paper we present these results, and compare them with some of the analysis of similar samples obtained in field trips to the Lake Eyre Basin of central Australia, the primary source region of the dust. In particular, the Fe/Al ratios (~0.9) are similar to LEB values, and higher than northern hemisphere values (~0.55). Salt entrainment indicates a source near dry lakes.

    Keenan, T.; Joe, P.; Wilson, J.; Collier, C.; Golding, B.; Burgess, D.; May, P.; Pierce, C.; Bally, J.; Crook, A.; Seed, A.; Sills, D.; Berry, L.; Potts, R.; Bell, I.; Fox, N.; Ebert, E.; Eilts, M.;  O'Loughlin, K.;  Webb, R.;  Carbone, R.;  Browning, K.;  Roberts, R.;  Mueller, C.


    The first World Weather Research Programme (WWRP) Forecast Demonstration Project (FDP), with a focus on nowcasting, was conducted in Sydney, Australia, from 4 September to 21 November 2000 during a period associated with the Sydney 2000 Olympic Games. Through international collaboration, nine nowcasting systems from the United States, United Kingdom, Canada, and Australia were deployed at the Sydney Office of the Bureau of Meteorology (BOM) to demonstrate the capability of modern forecast systems and to quantify the associated benefits in the delivery of a real-time nowcast service. On-going verification and impact studies supported by international committees assisted by the WWRP formed an integral part of this project. A description is given of the project, including component systems, the weather, and initial outcomes. Initial results show that the nowcasting systems tested were transferable and able to provide valuable information enhancing BOM nowcasts. The project provided for unprecedented interchange of concepts and ideas between forecasters, researchers, and end users in an operational framework where they all faced common issues relevant to real time nowcast decision making. A training workshop sponsored by the World Meteorological Organization (WMO) was also held in conjunction with the project so that other member nations could benefit from the FDP.

  18. Evaluating the clinical teaching of medical imaging students at Curtin University of Technology, Australia. (United States)

    Almohiy, H M; Davidson, R


    To ascertain the effectiveness of the clinical, tutorial-based component of teaching and the clinical assessment method in the Bachelor of Medical Imaging Science at Curtin University of Technology (CUT), Perth, Western Australia. In mid-2006, second- and third-year students enrolled in CUT's Medical Imaging Science degree were asked to complete a questionnaire assessing the Objective Structured Clinical Examination (OSCE) evaluation program and clinical teaching. Thirty-three of 57 students answered questions about demographics and their opinions of the laboratory sessions, clinical placements and the OSCEs. Seventy-six per cent of students were satisfied with their laboratory sessions and clinical placements. Sixty-four percent of respondents indicated that the OSCE was not an objective evaluation, but 82% of students felt the OSCE was an effective test of their radiography skills and knowledge, and believed that they were able to evaluate and care for a patient during the OSCE. Overall, the surveyed students believed that the practical skills explored in laboratory sessions helped improve clinical training outcomes; however, only 33% of the students were satisfied that the OSCE was an appropriate assessment of their clinical training in hospitals.

  19. Social media and digital technology use among Indigenous young people in Australia: a literature review. (United States)

    Rice, Emma S; Haynes, Emma; Royce, Paul; Thompson, Sandra C


    The use of social media and digital technologies has grown rapidly in Australia and around the world, including among Indigenous young people who face social disadvantage. Given the potential to use social media for communication, providing information and as part of creating and responding to social change, this paper explores published literature to understand how Indigenous Australian youth use digital technologies and social media, and its positive and negative impacts. Online literature searches were conducted in three databases: PubMed, Google Scholar and Informit in August 2014; with further searches of additional relevant databases (Engineering Village; Communication & mass media complete; Computers & applied sciences complete; Web of Science) undertaken in May 2015. In addition, relevant literature was gathered using citation snowballing so that additional peer-reviewed and grey literature was included. Articles were deemed relevant if they discussed social media and/or digital technologies and Indigenous Australians. After reading and reviewing all relevant articles, a thematic analysis was used to identify overall themes and identify specific examples. A total of 22 papers were included in the review. Several major themes were identified about how and why Indigenous young people use social media: identity, power and control, cultural compatibility and community and family connections. Examples of marketing for health and health promotion approaches that utilize social media and digital technologies were identified. Negative uses of social media such as cyber bullying, cyber racism and the exchange of sexually explicit content between minors are common with limited approaches to dealing with this at the community level. Strong cultural identity and community and family connections, which can be enhanced through social media, are linked to improved educational and health outcomes. The confidence that Indigenous young people demonstrate when approaching the

  20. Assessing the vulnerability of buildings to tsunami in Sydney

    Directory of Open Access Journals (Sweden)

    F. Dall'Osso


    Full Text Available Australia is vulnerable to the impacts of tsunamis and exposure along the SE coast of New South Wales is especially high. Significantly, this is the same area reported to have been affected by repeated large magnitude tsunamis during the Holocene. Efforts are under way to complete probabilistic risk assessments for the region but local government planners and emergency risk managers need information now about building vulnerability in order to develop appropriate risk management strategies. We use the newly revised PTVA-3 Model (Dall'Osso et al., 2009 to assess the relative vulnerability of buildings to damage from a "worst case tsunami" defined by our latest understanding of regional risk – something never before undertaken in Australia. We present selected results from an investigation of building vulnerability within the local government area of Manly – an iconic coastal area of Sydney. We show that a significant proportion of buildings (in particular, residential structures are classified as having "High" and "Very High" Relative Vulnerability Index scores. Furthermore, other important buildings (e.g., schools, nursing homes and transport structures are also vulnerable to damage. Our results have serious implications for immediate emergency risk management, longer-term land-use zoning and development, and building design and construction standards. Based on the work undertaken here, we recommend further detailed assessment of the vulnerability of coastal buildings in at risk areas, development of appropriate risk management strategies and a detailed program of community engagement to increase overall resilience.

  3. Sydney harbourings, rehabilitations and the politics of procurement

    Directory of Open Access Journals (Sweden)

    Catherine de Lorenzo


    Full Text Available In the last three years Sydney has been transformed to an unprecedented extent by public art projects, most of which have been developed by government instrumentalities, agencies or partnerships. The central city council has initiated a Sculpture Walk through the streets and around the rocky foreshores of the inner city; the Sydney Olympic site at Homebush Bay is home to a number of public art works; the government’s water utility company has sponsored an annual, temporary art installation walk along a spectacularly rugged ocean escarpment linking several medium-density suburbs; another instrumentality recently established to oversee the reuse of abandoned heavy industrial sites in the harbour, has established the ‘Promenart’ program along fifteen kilometres of harbour foreshores; and a government-appointed statutory authority responsible for the redevelopment of an extensive and highly polluted former industrial site between the CDB and the airport, has worked closely with designers and artists to develop comprehensive briefs addressing environmental rehabilitation and social interaction. This impressive list is by no means exhaustive. The surge in bureaucratic and artistic creative energy demands critical evaluation. In this paper I will contrast two sets of projects. This first concerns actual projects, in or near the spectacular Sydney Harbour setting, which are premised on placemaking principles and on the whole elicit actual or imagined histories for the delight and reverie of the promenader. Despite the popular and aesthetic success of these projects, one of them, the ambitious Sculpture Walk, is currently being re-evaluated. The second set, in more mundane suburban environments and centred on toxic waterways, concerns projects that at this stage are either being implemented or nearing commencement by interdisciplinary groups of artists, designers, engineers, environmentalists, community representatives, and other specialists.

  4. A portrait of prefrontal lobotomy performed at the Royal Prince Alfred Hospital in Sydney by Dr Rex Money. (United States)

    White, Richard T; McGee-Collett, Martin


    The objective of this article is to provide a portrait of prefrontal lobotomy performed at the Royal Prince Alfred Hospital, Sydney by the Head of Neurosurgery Dr Rex Money and to describe Dr Money's role in the promotion of psychosurgery in Sydney. We draw attention to an oral presentation by Dr Rex Money in 1951, a journal article written by Money, archival information held at the Royal Prince Alfred Hospital, including Dr Money's accounts of his travels and his reports regarding neurosurgery - both internationally and in Australia. Dr Rex Money performed a series of 13 prefrontal lobotomies between 1945 and 1951, and presented the theoretical basis for his series, his operative procedures and the outcomes at the annual meeting of its medical officers' association. Notwithstanding various deficiencies in his clinical research, Money's descriptions give a relatively comprehensive account of one of the first series of prefrontal lobotomies performed in Australia. The current article also describes Dr Money's contributions to the promotion of psychosurgery in Sydney, and illustrates the participation of a senior neurosurgeon and of a major Sydney teaching hospital during the psychosurgery saga. © The Royal Australian and New Zealand College of Psychiatrists 2016.

  5. A human thermal climatology of subtropical Sydney (United States)

    Spagnolo, J. C.; de Dear, R. J.


    Using a physiologically relevant thermal comfort index (OUT_SET*), an analysis of the week-by-week human thermal climate of Sydney was carried out for three levels of metabolic activity. The OUT_SET* index is an outdoor version of the widely used indoor comfort index called the standard effective temperature (SET*) incorporating air and mean radiant temperatures, relative humidity, air velocity, clothing insulation and activity level. The outdoor comfort zone for Sydney in terms of OUT_SET* was found from earlier subjective field studies to be in the range 23.8-28.5°C. The analysis indicated that the mid-summer period (weeks 43 through to 12 in the Southern Hemisphere) was most suitable for sedentary outdoor activities (e.g. watching spectator sport), whereas the mid-winter period was more suitable for light activities such as walking. Sydney's winter was found to be a very suitable season for tourism in many respects because of (a) low rainfall months, like August, and (b) the ability to undertake light activities while remaining within the outdoor comfort zone. For high metabolic activities during the day, for example the mass participation Sydney City-to-Surf fun run, it was found that the threshold limit value for increased risk of heat stress (as defined by ISO 7243, 1989) is exceeded up to 50% of the time during the summer (weeks 50 through to 9 at 3 p.m.) at the 90th percentile probability level. The methods and results of this study should be relevant to end-users such as architects, engineers, outdoor-event planners and the tourism industry in general.

  7. For the Bicultural Happy Few Only: Didier Coste’s Days in Sydney

    Directory of Open Access Journals (Sweden)

    Helene Jaccomard


    Full Text Available Written by Didier Coste, a French essayist, translator and academic who worked for some years in Australia, Days in Sydney is a unique bilingual novel. Instead of the accepted custom of the original text printed on the opposite page of its translation Days in Sydney contains no translation. It alternates French and English in a seamless fashion that is the antithesis of the conventions of bilingual texts, resulting in a truly heteroglossic text, elliptical in its construction as it meanders between two languages and two main characters. In the publication announcement Didier Coste stated that this unusual book was the result of an ‘nécessité esthétique et une certaine idée de la bi-culture’ aimed at ‘le petit cercle des bilingues d'Australie’. Alongside his creative output Coste has published scholarly works since the late 1980s up to 2004. In English. By examining the principles and practice of heteroglossia and by drawing on one of Coste’s recent academic article, this paper explores the twin notions of ‘nécessité esthétique”, and ‘bi-cultural’ readership to account for the (not so global space between two languages and cultures Days in Sydney occupies.

  9. Intensive sex partying amongst gay men in Sydney. (United States)

    Hurley, Michael; Prestage, Garrett


    Intensive sex partying is a framework developed to analyse specific frequent behaviours amongst a small minority of gay men in Sydney, Australia. The behaviours included a higher frequency of dance party attendance, more frequent sex, more anal sex, multiple sex partners, more unprotected anal intercourse with casual partners and more frequent drug taking. These occur at a contextual intersection between a sub-group of sexually adventurous gay men and 'party boys'. The men appear to be involved in both high-risk, adventurous sex practices and a specific form of partying distinguishable from dance partying and 'clubbing'. Sex partying occurs on multiple sites (domestic spaces; within dance parties; sex parties; sex-on-premises venues) and appears to be geared to the maximisation of sexual pleasure. Intensive sex partying describes this coincidence of factors and locates them in relation to the multiple pleasures offered by sex partying. It emphasises the importance of 'intensity' in order to understand better the relations between sex, drug use, pleasure, care and risk in some gay men's lives.

  11. Temperature, air pollution and total mortality during summers in Sydney, 1994-2004. (United States)

    Hu, Wenbiao; Mengersen, Kerrie; McMichael, Anthony; Tong, Shilu


    This study investigated the effect of temperature and air pollutants on total mortality in summers in Sydney, Australia. Daily data on weather variables, mortality and air pollution for the Sydney metropolitan area from 1 January 1994 to 31 December 2004 were supplied by Australian Bureau of Meteorology, Australian Bureau of Statistics, and Environment Protection Agency of New South Wales, respectively. We examined the association of total mortality with weather indicators and air pollution using generalised additive models (GAMs). A time-series classification and regression tree (CART) model was developed to explore the interaction effects of temperature and air pollution that impacted on mortality. Our results show that the average increase in total daily mortality was 0.9% [95% confidence interval (CI): 0.6-1.3%] and 22% (95% CI: 6.4-40.5%) for a 1 degrees C increase in daily maximum temperature and 1 part per hundred million (pphm) increase in daily average concentration of sulphur dioxide (SO(2)), respectively. Time-series CART results show that maximum temperature and SO(2) on the current day had significant interaction effects on total mortality. There were 7.3% and 12.1% increases in daily average mortality when maximum temperature was over 32 degrees C and mean SO(2) exceeded 0.315 pphm, respectively. Daily maximum temperature was statistically significantly associated with daily deaths in Sydney during summers between 1994 and 2004. Elevated daily maximum temperature combined with high SO(2) concentrations appeared to have contributed to the increased mortality observed in Sydney during this period.

Although rare in most other populations, the carrier frequency is one in 25 in Ashkenazi Jews. Australian high-school-based TSD preconception genetic screening programs aim to screen, educate, and optimize reproductive choice for participants. These programs have demonstrated high uptake, low psychological morbidity, and have been shown to result in fewer than expected Jewish TSD-affected births over 18 years of operation. The majority of Jewish individuals of reproductive age outside of the high school screening program setting in Australia have not accessed screening. Recent recommendations advocate supplementing the community high school screening programs with general practitioner- and obstetrician-led genetic screening of Ashkenazi Jewish individuals for TSD and other severe recessive diseases for which this group is at risk. Massively parallel DNA sequencing is expected to become the testing modality of choice over the coming years. Keywords: Tay-Sachs disease, genetic screening, Australia

  13. Vibrio cholerae O1 El Tor cluster in Sydney linked to imported whitebait. (United States)

    Forssman, Bradley; Mannes, Trish; Musto, Jennie; Gottlieb, Thomas; Robertson, Graham; Natoli, Jonathan D; Shadbolt, Craig; Biffin, Brian; Gupta, Leena


    Three cases of cholera in women aged 71, 72 and 84 years were notified in November 2006 in Sydney, New South Wales. This is the first reported cluster of cholera in Australia for over 30 years, and was an unusual outbreak in patients with no history of recent travel to cholera-endemic areas. A food trace-back investigation found that the only exposure common to all cases was consumption of raw whitebait imported from Indonesia. This outbreak demonstrates that the practice of eating raw whitebait does occur in Australia, albeit in the process of taste-testing uncooked fritter batter. All three patients were undergoing long-term therapy with proton-pump inhibitors, which may have contributed to their susceptibility to the disease. A review of importation practices of food from cholera-endemic regions may be required to prevent future transmission.

  14. Spatiotemporal Dynamics of Vibrio spp. within the Sydney Harbour Estuary (United States)

    Siboni, Nachshon; Balaraju, Varunan; Carney, Richard; Labbate, Maurizio; Seymour, Justin R.


    Vibrio are a genus of marine bacteria that have substantial environmental and human health importance, and there is evidence that their impact may be increasing as a consequence of changing environmental conditions. We investigated the abundance and composition of the Vibrio community within the Sydney Harbour estuary, one of the most densely populated coastal areas in Australia, and a region currently experiencing rapidly changing environmental conditions. Using quantitative PCR (qPCR) and Vibrio-specific 16S rRNA amplicon sequencing approaches we observed significant spatial and seasonal variation in the abundance and composition of the Vibrio community. Total Vibrio spp. abundance, derived from qPCR analysis, was higher during the late summer than winter and within locations with mid-range salinity (5–26 ppt). In addition we targeted three clinically important pathogens: Vibrio cholerae, V. Vulnificus, and V. parahaemolyticus. While toxigenic strains of V. cholerae were not detected in any samples, non-toxigenic strains were detected in 71% of samples, spanning a salinity range of 0–37 ppt and were observed during both late summer and winter. In contrast, pathogenic V. vulnificus was only detected in 14% of samples, with its occurrence restricted to the late summer and a salinity range of 5–26 ppt. V. parahaemolyticus was not observed at any site or time point. A Vibrio-specific 16S rRNA amplicon sequencing approach revealed clear shifts in Vibrio community composition across sites and between seasons, with several Vibrio operational taxonomic units (OTUs) displaying marked spatial patterns and seasonal trends. Shifts in the composition of the Vibrio community between seasons were primarily driven by changes in temperature, salinity and NO2, while a range of factors including pH, salinity, dissolved oxygen (DO) and NOx (Nitrogen Oxides) explained the observed spatial variation. Our evidence for the presence of a spatiotemporally dynamic Vibrio community

  17. The scientific legacy of Sydney Chapman (United States)

    Akasofu, Syun-Ichi


    Sydney Chapman (1888-1970) was arguably one of the greatest scientists of the twentieth century. His comprehensive work on the kinetic theory of gases and solar-terrestrial physics, as well as on the mechanisms behind the formation of Earth's ozone layer, has inspired a wide swath of research spanning several generations [Van Allen, 1970]. Chapman, a member of the Royal Society, in London, and president of the International Geophysical Year (IGY), also was a recipient of AGU's William Bowie Medal. Young AGU members today may recognize Chapman from the topical conferences that carry his name. Although his biography has so far not been published, he gave three talks on his life: two at the National Center for Atmospheric Research, Boulder, Colo., in 1965 and 1966, and one at the Geophysical Institute, University of Alaska Fairbanks, in 1967 (see Figure 1). All three are transcribed and included in a book, Sydney Chapman, Eighty: From His Friends [Akasofu et al., 1968]. These talks, combined with other sources, shed light on this insightful and discerning scientist.

  18. Monitoring outcomes of environmental service provision in low socio-economic indigenous Australia using innovative CyberTracker Technology

    Directory of Open Access Journals (Sweden)

    E J Ens


    Full Text Available Payments for environmental services (PES are increasingly promoted as an economic mechanism that could potentially address socio-economic and environmental conservation objectives in developing regions. However, the reporting and conditionality requirements of PES projects can be inhibitory, particularly for people with low environmental monitoring or administration capacity. Here, I provide five case studies where Indigenous Land and Sea Management groups in remote northern Australia, have combined Indigenous ecological knowledge, Western science, and the innovative CyberTracker technology to record and monitor the ecological outcomes of their land management activities to facilitate engagement with mainstream economies in Australia. The case studies elucidate methods of data collection and recording for established and potential PES projects where environmental monitoring and adaptive land and sea management are clear objectives, with longer term prospects for socio-economic benefits of Indigenous community education, empowerment and development. Similar monitoring and reporting methods could be applied in other contexts where individuals or community groups want to engage in emerging mainstream environmental service markets, but lack environmental monitoring and reporting capacity, such as other Indigenous groups, people from economically poor regions, or farmers in environmentally valuable regions.

  19. Understanding invasion history and predicting invasive niches using genetic sequencing technology in Australia: case studies from Cucurbitaceae and Boraginaceae (United States)

    Shaik, Razia S.; Zhu, Xiaocheng; Clements, David R.; Weston, Leslie A.


    Part of the challenge in dealing with invasive plant species is that they seldom represent a uniform, static entity. Often, an accurate understanding of the history of plant introduction and knowledge of the real levels of genetic diversity present in species and populations of importance is lacking. Currently, the role of genetic diversity in promoting the successful establishment of invasive plants is not well defined. Genetic profiling of invasive plants should enhance our understanding of the dynamics of colonization in the invaded range. Recent advances in DNA sequencing technology have greatly facilitated the rapid and complete assessment of plant population genetics. Here, we apply our current understanding of the genetics and ecophysiology of plant invasions to recent work on Australian plant invaders from the Cucurbitaceae and Boraginaceae. The Cucurbitaceae study showed that both prickly paddy melon (Cucumis myriocarpus) and camel melon (Citrullus lanatus) were represented by only a single genotype in Australia, implying that each was probably introduced as a single introduction event. In contrast, a third invasive melon, Citrullus colocynthis, possessed a moderate level of genetic diversity in Australia and was potentially introduced to the continent at least twice. The Boraginaceae study demonstrated the value of comparing two similar congeneric species; one, Echium plantagineum, is highly invasive and genetically diverse, whereas the other, Echium vulgare, exhibits less genetic diversity and occupies a more limited ecological niche. Sequence analysis provided precise identification of invasive plant species, as well as information on genetic diversity and phylogeographic history. Improved sequencing technologies will continue to allow greater resolution of genetic relationships among invasive plant populations, thereby potentially improving our ability to predict the impact of these relationships upon future spread and better manage invaders possessing

    Labour economists have been increasingly interested in the impact of technological change upon employment and unemployment. However, the predominant focus of empirical studies has been on employment and unemployment stocks, whereas technological change is more likely to affect the flows of labour. This paper focuses on the latter issue. In particular, given the technological change, two major questions posed in this paper are: (i) who moves from low-tech to high-tech jobs and who moves from h...

  3. Disease control during the colonial period in Australia. (United States)

    Turner, A J


    The first permanent European settlers of Australia arrived in 1788 to establish a penal colony at Sydney, New South Wales (NSW). As the colony grew and wool production increased, more free settlers and emancipists developed farming in inland Australia. During the 1840s veterinarians commenced arriving in small numbers but they were not closely associated with the development and execution of disease control programs, which was left to lay inspectors of stock. The arrival of William Tyson Kendall and coordinated action with Graham Mitchell led to the establishment of a private veterinary college following the passage of veterinary surgeons legislation in Victoria. From this time, veterinarians came to be appointed to positions formerly occupied by lay inspectors and the veterinary profession was able to take up the role of planning and executing government-led disease control programs. From a colony relying on wool for export to the UK, technical advancements in meat freezing and pasture improvement widened the range and increased the quantity of exported products. Before the advent of veterinary advances, sheep scab was eradicated, a vaccine was developed for anthrax and glanders infection of horses was prevented entry to Australia. Graduates from the Melbourne Veterinary College spread across Australia and in this period a conservative quarantine policy was developed following inaction to control an outbreak of contagious bovine pleuropneumonia (CBPP) and the escape of rabbits to form a plague across the continent. Coordinated control of CBPP had to await the next century and advancement of technology increased our understanding of bacteriology and immunity of infectious diseases. Veterinary services were provided to the militia sent by the colonies to the Boer Wars in South Africa 1987-1901 and the veterinarians from Victoria were led by an Australian trained veterinarian.

  4. The potential for modification in cloning and vitrification technology to enhance genetic progress in beef cattle in Northern Australia. (United States)

    Taylor-Robinson, Andrew W; Walton, Simon; Swain, David L; Walsh, Kerry B; Vajta, Gábor


    Recent advances in embryology and related research offer considerable possibilities to accelerate genetic improvement in cattle breeding. Such progress includes optimization and standardization of laboratory embryo production (in vitro fertilization - IVF), introduction of a highly efficient method for cryopreservation (vitrification), and dramatic improvement in the efficiency of somatic cell nuclear transfer (cloning) in terms of required effort, cost, and overall outcome. Handmade cloning (HMC), a simplified version of somatic cell nuclear transfer, offers the potential for relatively easy and low-cost production of clones. A potentially modified method of vitrification used at a centrally located laboratory facility could result in cloned offspring that are economically competitive with elite animals produced by more traditional means. Apart from routine legal and intellectual property issues, the main obstacle that hampers rapid uptake of these technologies by the beef cattle industry is a lack of confidence from scientific and commercial sources. Once stakeholder support is increased, the combined application of these methods makes a rapid advance toward desirable traits (rapid growth, high-quality beef, optimized reproductive performance) a realistic goal. The potential impact of these technologies on genetic advancement in beef cattle herds in which improvement of stock is sought, such as in northern Australia, is hard to overestimate.

  5. The Prevalence of Angiostrongylus cantonensis/mackerrasae Complex in Molluscs from the Sydney Region.

    Douglas Chan

    Full Text Available Angiostrongylus cantonensis and Angiostrongylus mackerrasae are metastrongyloid nematodes that infect various rat species. Terrestrial and aquatic molluscs are intermediate hosts of these worms while humans and dogs are accidental hosts. Angiostrongylus cantonensis is the major cause of angiostrongyliasis, a disease characterised by eosinophilic meningitis. Although both A. cantonensis and A. mackerrasae are found in Australia, A. cantonensis appears to account for most infections in humans and animals. Due to the occurrence of several severe clinical cases in Sydney and Brisbane, the need for epidemiological studies on angiostrongyliasis in this region has become apparent. In the present study, a conventional PCR and a TaqMan assay were compared for their ability to amplify Angiostrongylus DNA from DNA extracted from molluscs. The TaqMan assay was more sensitive, capable of detecting the DNA equivalent to one hundredth of a nematode larva. Therefore, the TaqMan assay was used to screen molluscs (n=500 of 14 species collected from the Sydney region. Angiostrongylus DNA was detected in 2 of the 14 mollusc species; Cornu aspersum [14/312 (4.5%], and Bradybaenia similaris [1/10 (10%], which are non-native terrestrial snails commonly found in urban habitats. The prevalence of Angiostrongylus spp. was 3.0% ± 0.8% (CI 95%. Additionally, experimentally infected Austropeplea lessoni snails shed A. cantonensis larvae in their mucus, implicating mucus as a source of infection. This is the first Australian study to survey molluscs using real-time PCR and confirms that the garden snail, C. aspersum, is a common intermediate host for Angiostrongylus spp. in Sydney.

  6. Sydney epilepsy incidence study to measure illness consequences: the SESIMIC observational epilepsy study protocol

    Full Text Available Abstract Background Epilepsy affects an estimated 50 million people and accounts for approximately 1% of days lost to ill health globally, making it one of the most common, serious neurological disorders. While there are abundant global data on epilepsy incidence, prevalence and treatment, there is a paucity of Australian incidence data. There is also a general lack of information on the psychosocial impact and socioeconomic consequences of a new diagnosis of epilepsy on an individual, their family, household, and community which are often specific to the health and social system of each country. Methods/Design The Sydney Epilepsy Incidence Study to Measure Illness Consequences (SEISMIC is an Australian population-based epilepsy incidence and outcome study that will recruit every newly diagnosed case of epilepsy in the Sydney South West Area Health Service to an epilepsy register. Multiple and overlapping sources of notification will be used to identify all new cases of epilepsy over a 24 month period in the Eastern Zone of the Sydney South West Area Health Service (SSWAHS and follow up will occur over 12 months. SEISMIC will use the International League Against Epilepsy (ILAE definitions and classifications for epidemiologic studies of epilepsy. The study will examine outcomes including mood, quality of life, employment, education performance, driving status, marital and social problems, medication use, health care usage, costs and stigma. Discussion This study is designed to examine how clinical, psychological factors, socioeconomic circumstances, and healthcare delivery influence the experience of epilepsy for individuals and families allowing better targeting of specific services and informing policy makers and practitioners. In addition, the study will provide the basis for a longitudinal population-based cohort study and potentially inform qualitative sub-studies and randomised controlled trials of intervention strategies.

    Full Text Available Norovirus is the primary cause of acute gastroenteritis in individuals of all ages. In Australia, a new strain of norovirus (GII.4 was identified in March 2012, and this strain has spread rapidly around the world. In August 2012, this new GII.4 strain was identified in patients in South Korea. Therefore, to examine the characteristics of the epidemic norovirus GII.4 2012 variant in South Korea, we conducted KM272334 full-length genomic analysis. The genome of the gg-12-08-04 strain consisted of 7,558 bp and contained three open reading frame (ORF composites throughout the whole genome: ORF1 (5,100 bp, ORF2 (1,623 bp, and ORF3 (807 bp. Phylogenetic analyses showed that gg-12-08-04 belonged to the GII.4 Sydney 2012 variant, sharing 98.92% nucleotide similarity with this variant strain. According to SimPlot analysis, the gg-12-08-04 strain was a recombinant strain with breakpoint at the ORF1/2 junction between Osaka 2007 and Apeldoorn 2008 strains. This study is the first report of the complete sequence of the GII.4 Sydney 2012 strain in South Korea. Therefore, this may represent the standard sequence of the norovirus GII.4 2012 variant in South Korea and could therefore be useful for the development of norovirus vaccines.

    Full text: Recently, 15% of elderly Japanese-American women have been shown to have marked heterogeneity of bone mineral density (BMD) between measured sites. The purposes of this study were to determine (1 ) the prevalence of this finding in an Australian population; and (2) potential association with clinical factors such as age, years since menopause (YSM), alcohol, smoking, family history, exercise, and body mass index. One hundred and fourteen peri-or post- menopausal Caucasian women (mean age 55 + 8.8 years) were referred for osteoporotic (OP) fracture risk assessment. Patients (pts) had no disorders or drugs known to affect BMD and no evidence of scoliosis or arthritic change. Bone densitometry of the lumbar spine (PA), hip and distal radius were measured using a Norland XR-26. According to WHO criteria, 30 pts (26%) were normal (T score > -1) at all sites; no pts (0%) had generalised OP (T score < -2.5); 29 (25%) had OP in one or two sites only (hip = 25, spine = 13, wrist = 1); the remaining 55 pts (48%) were osteogenic (-2.5 < T score < -1) in at least one site. Using multivariate logistic regression analysis, only YSM predicted regional OP (odds ratio = 1.14; pSydney women; of clinical factors only YSM is independently associated with regional OP. Fracture risk classification may be improved by BMD measurement of multiple sites.

  13. Leveraging VGI Integrated with 3D Spatial Technology to Support Urban Intensification in Melbourne, Australia

    Directory of Open Access Journals (Sweden)

    Soheil Sabri


    Full Text Available High density residential development in metropolitan Melbourne, where contradictory imperatives of neighbourhood character and urban intensification play important roles, remains an uncertain practice. One key issue for plan implementation is the lack of consistency between authorities, developers and the community in interpreting the standards, design guidelines, and state/local strategies, especially those relating to neighbourhood character. There is currently no mechanism to incorporate community perceptions and place experiences as subjective aspects of neighbourhood character in development assessments. There is also little use of micro-scale and multi-dimensional spatial analysis to integrate these subjective aspects with objective measures (e.g. building volume and height; streetscape to communicate effectively—and in a limited timeframe—with all stakeholders. This paper explores the potential of two emerging geospatial technologies that can be leveraged to respond to these problems. Evidence in the literature suggests that volunteered geographic information (VGI can provide community input around subjective aspects of the urban environment. In addition, a deluge of three-dimensional (3D spatial information (e.g. 3D city models is increasingly available for micro-level (building- or property-level assessment of the physical aspects of the urban environment. This paper formulates and discusses a conceptual framework to link these two spatial technological advancements in a virtual geographic environment (VGE that accounts for micro-scale 3D spatial analysis incorporating both subjective and objective aspects of neighbourhood character relevant in implementing compact city strategies.

  14. Strategies for the municipal waste management system to take advantage of carbon trading under competing policies: The role of energy from waste in Sydney. (United States)

    El Hanandeh, Ali; El-Zein, Abbas


    Climate change is a driving force behind some recent environmental legislation around the world. Greenhouse gas emission reduction targets have been set in many industrialised countries. A change in current practices of almost all greenhouse-emitting industrial sectors is unavoidable, if the set targets is to be achieved. Although, waste disposal contributes around 3% of the total greenhouse gas emissions in Australia (mainly due to fugitive methane emissions from landfills), the carbon credit and trading scheme set to start in 2010 presents significant challenges and opportunities to municipal solid waste practitioners. Technological advances in waste management, if adopted properly, allow the municipal solid waste sector to act as carbon sink, hence earning tradable carbon credits. However, due to the complexity of the system and its inherent uncertainties, optimizing it for carbon credits may worsen its performance under other criteria. We use an integrated, stochastic multi-criteria decision-making tool that we developed earlier to analyse the carbon credit potential of Sydney municipal solid waste under eleven possible future strategies. We find that the changing legislative environment is likely to make current practices highly non-optimal and increase pressures for a change of waste management strategy.

  15. Evaluation of radioxenon releases in Australia using atmospheric dispersion modelling tools. (United States)

    Tinker, Rick; Orr, Blake; Grzechnik, Marcus; Hoffmann, Emmy; Saey, Paul; Solomon, Stephen


    The origin of a series of atmospheric radioxenon events detected at the Comprehensive Test Ban Treaty Organisation (CTBTO) International Monitoring System site in Melbourne, Australia, between November 2008 and February 2009 was investigated. Backward tracking analyses indicated that the events were consistent with releases associated with hot commission testing of the Australian Nuclear Science Technology Organisation (ANSTO) radiopharmaceutical production facility in Sydney, Australia. Forward dispersion analyses were used to estimate release magnitudes and transport times. The estimated (133)Xe release magnitude of the largest event (between 0.2 and 34 TBq over a 2 d window), was in close agreement with the stack emission releases estimated by the facility for this time period (between 0.5 and 2 TBq). Modelling of irradiation conditions and theoretical radioxenon emission rates were undertaken and provided further evidence that the Melbourne detections originated from this radiopharmaceutical production facility. These findings do not have public health implications. This is the first comprehensive study of atmospheric radioxenon measurements and releases in Australia.

  1. Barriers to the use of Information and Communication Technology by occupational therapists working in a rural area of New South Wales, Australia. (United States)

    Chedid, Rebecca Jean; Dew, Angela; Veitch, Craig


    This qualitative study formed part of a large-scale, multi-phase study into the delivery of therapy services to people with a disability, living in one rural area of New South Wales, Australia. The study's purpose was to identify the impact of Information and Communication Technology on the workforce practices of occupational therapists' working in a rural area of New South Wales. Individual semi-structured telephone interviews were conducted with 13 occupational therapists working in disability, health and private practice in a rural area of New South Wales. Participants were asked about access to, skills and limitations of using Information and Communication Technology. A modified grounded theory approach, based on thematic analysis and constant comparison, was used to analyse the interview transcripts. This study found widespread use of technology by rurally based occupational therapists working in the disability sector in New South Wales. However, Information and Communication Technology was primarily used for client contact, professional development and professional networking rather than therapy provision. The study identified individual, workplace and community barriers to greater uptake of Information and Communication Technology by this group. The individual barriers included: age cohort, knowledge and personal preferences. The workplace barriers included: support and training and availability of resources. The community barriers included: infrastructure and perceptions of clients' acceptance. The potential exists for Information and Communication Technology to supplement face-to-face therapy provision, enhance access to professional development and reduce professional isolation thereby addressing the rural challenges of large distances, travel times and geographic isolation. To overcome these challenges, individual, workplace and community Information and Communication Technology barriers should be addressed concurrently. © 2012 The Authors Australian

  2. Veterinary parasitology teaching in eastern Australia. (United States)

    Gasser, R B; Beveridge, I; Sangster, N C; Coleman, G


    There are tendencies in universities globally to change undergraduate teaching in veterinary parasitology. To be able to give considered advice to universities, faculties, governmental bodies and professional societies about a discipline and to establish how particular changes may impact on the quality of a course, is the requirement to record and review its current status. The present paper contributes toward this objective by providing a "snap-shot" of the veterinary parasitology courses at the Universities of Melbourne, Sydney and Queensland in eastern Australia. It includes a description of the veterinary science curriculum in each institution, and provides an outline of its veterinary parasitology course, including objectives, topics covered, course delivery, student examination procedures and course evaluation. Student contact time in veterinary parasitology during the curriculum is currently higher in Melbourne (183 h) compared with Sydney and Queensland (106-110 h). In the teaching of parasitology, Melbourne adopts a taxonomic approach (in the pre-clinical period) followed by a combined disciplinary and problem-based approach in the clinical semesters, whereas both Sydney and Queensland focus more on presenting parasites on a host species-basis followed by a problem-based approach.

  3. The impact of climate change on ozone-related mortality in Sydney. (United States)

    Physick, William; Cope, Martin; Lee, Sunhee


    Coupled global, regional and chemical transport models are now being used with relative-risk functions to determine the impact of climate change on human health. Studies have been carried out for global and regional scales, and in our paper we examine the impact of climate change on ozone-related mortality at the local scale across an urban metropolis (Sydney, Australia). Using three coupled models, with a grid spacing of 3 km for the chemical transport model (CTM), and a mortality relative risk function of 1.0006 per 1 ppb increase in daily maximum 1-hour ozone concentration, we evaluated the change in ozone concentrations and mortality between decades 1996-2005 and 2051-2060. The global model was run with the A2 emissions scenario. As there is currently uncertainty regarding a threshold concentration below which ozone does not impact on mortality, we calculated mortality estimates for the three daily maximum 1-hr ozone concentration thresholds of 0, 25 and 40 ppb. The mortality increase for 2051-2060 ranges from 2.3% for a 0 ppb threshold to 27.3% for a 40 ppb threshold, although the numerical increases differ little. Our modeling approach is able to identify the variation in ozone-related mortality changes at a suburban scale, estimating that climate change could lead to an additional 55 to 65 deaths across Sydney in the decade 2051-2060. Interestingly, the largest increases do not correspond spatially to the largest ozone increases or the densest population centres. The distribution pattern of changes does not seem to vary with threshold value, while the magnitude only varies slightly.

  5. Social Capital, Local Communities and Culture-led Urban Regeneration Processes: The Sydney Olympic Park Experience

    Directory of Open Access Journals (Sweden)

    Jason Hugh Prior


    Full Text Available Culture has become increasingly important in regeneration processes designed to deal with urban futures. Urban regeneration processes in which culture has played a prominent role range from large-scale public investments in cultural facilities and artefacts as ‘hallmarks’ of urban regeneration projects (e.g. Guggenheim Bilbao, through to the use of ‘one shot’ cultural events such as the Olympic Games as a catalyst and engine for regenerating urban areas. The aim of this paper is to examine the association between social capital (SC, local communities and the culture-led regeneration process at Sydney Olympic Park (SOP, New South Wales, Australia. The catalyst for the transformation of an industrial wasteland into SOP was the awarding of the Olympics to Sydney in 1993. A convenience sample of 47 professional reports associated with the regeneration process at SOP between 1993 and 2010 were analyzed, the aim being to understand how local communities had been linked to the regeneration process through SC. Results from the analysis identified three principal associations between SC, local communities and the ongoing SOP regeneration process. The first association related to how, during the early years of the regeneration process, SC was used as a means of expressing concern about how governance mechanisms implemented at SOP might adversely impact the ability of local communities to engage in decision making that affected their local environment. The second related to the use of community development programs to build SC in local communities through the SOP development. The third related to a call for the development of measures to understand how the development of SOP impacts on the SC in local communities. Eight in-depth interviews with professionals involved in the regeneration process were used to provide further insights into the three principal associations. The paper discusses findings through reference to broader arguments surrounding

  7. Uranium exploration and mining in Australia

    Energy Technology Data Exchange (ETDEWEB)

    Wutzler, B.

    Uranium minerals were discovered in Australia in the years 1850 to 1900 already, but most of them were not recognised as such. It was not until 1894 that the first significant uranium find was made in Carcoar, west of Sydney. At that time, the uranium output of the world, which only amounted to a few hundred cwts, was for the most part obtained from mining areas close to the border between Saxony and Bohemia. In South Australia, uranium ore was mined experimentally for the production of radium at Radium Hill from 1906 onwards and at Mt. Painter from 1910 onwards. It was not until World War II, however, that uranium gained importance as a valuable raw material that could also be used for military purposes. The second phase of uranium mining in Australia commenced in 1944. Within ten years Australia's presumed uranium potential was confirmed by extensive exploration. The development of uranium mining in Australia is described in the present paper.

  8. The Loss of HMAS Sydney II: Medical Aspects

    Directory of Open Access Journals (Sweden)

    Neil Westphalen


    Full Text Available On 19 November 1941, HMAS Sydney was 100nm off Shark Bay, on her way back to Fremantle after escorting the troopship Zealandia to Sunda Strait, between Java and Sumatra. At 1600 she encountered the German auxiliary cruiser Kormoran. The ensuring battle began at 1730 and ended at 1825. Sydney was last seen on fire at 2300 while Kormoran was scuttled and sank just after midnight. There were 318 survivors from Kormoran’s crew of 399, but no survivors from Sydney’s crew of 645. Both wrecks were found in March 2008 and this led to a Commission of Inquiry to address the various controversies and conspiracy theories related to Sydney’s loss.

    Robertson, J G; Ireland, M J; Tuthill, P G; Tango, W J; Jacob, A P; North, J R; Brummelaar, T A ten


    The University of Sydney has a long history in optical stellar interferometry. The first project, in the 1960s, was the Narrabri Stellar Intensity Interferometer, which measured the angular diameters of 32 hot stars and established the temperature scale for spectral classes O - F. That instrument was followed by the Sydney University Stellar Interferometer (SUSI), which is now undergoing a third-generation upgrade, to use the multi-wavelength PAVO beam combiner. SUSI operates at visible rather than IR wavelengths and has baselines up to 160 m, so it is well suited to the study of hot stars. A number of studies have been carried out, and more are planned when commissioning of the PAVO system is complete. Conversion of the system to allow remote operation will allow larger scientific projects to be undertaken.

    The Muggah Creek Watershed, a tidal estuary located in Sydney, Nova Scotia, is known locally as the Tar Ponds. Over the past century, the Tar Ponds have accumulated contaminants in the contributing watershed from the iron, steel and coke manufacturing. There are sediments contaminated with polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs). A groundwater modelling program was developed to estimate current contaminant fluxes to the estuary and site streams, through groundwater. Attempts were made to incorporate a complex stratigraphic profile, where groundwater flow and contaminant transport is strongly controlled by shallow fractured bedrock, into the conceptual model developed for the site. This conceptual model for groundwater flow and contaminant transport at the Sydney Tar Ponds site was presented. The complex flow patterns between bedrock and overburden, and between the bedrock units and surface water bodies were illustrated with model simulations. It was found that groundwater flow was dominated by discharge to the streams and the estuary. 6 refs., 2 tabs., 11 figs.

    Full Text Available This article explores the intersection between digital technologies and cultural planning. New information technologies ought to enable more powerful planning strategies. Yet a common seductive vision of planning is mirrored by utopian claims for cyberculture, which often fall short of the hoped-for reality. We suggest that one problem is the linear thinking common to mainstream planning and digital thinking, which leads to a cumulative lack of fit with the non-linear (chaotic world of social action. We draw on chaos and complexity theory to reframe planning problems and develop more creative digital strategies in a specific location, Western Sydney, using and adapting Geographic Information Systems.

  12. Characteristics of the 14 April 1999 Sydney hailstorm based on ground observations, weather radar, insurance data and emergency calls

    Directory of Open Access Journals (Sweden)

    S. S. Schuster


    Full Text Available Hailstorms occur frequently in metropolitan Sydney, in the eastern Australian State of New South Wales, which is especially vulnerable due to its building exposure and geographical location. Hailstorms challenge disaster response agencies and pose a great risk for insurance companies. This study focuses on the Sydney hailstorm of 14 April 1999 – Australia's most expensive insured natural disaster, with supporting information from two other storms. Comparisons are drawn between observed hailstone sizes, radar-derived reflectivity and damage data in the form of insurance claims and emergency calls. The 'emergency response intensity' (defined by the number of emergency calls as a proportion of the total number of dwellings in a Census Collection District is a useful new measure of the storm intensity or severity experienced. The area defined by a radar reflectivity ≥55 dBZ appears to be a good approximation of the damage swath on ground. A preferred area for hail damage is located to the left side of storm paths and corresponds well with larger hailstone sizes. Merging hail cells appear to cause a substantially higher emergency response intensity, which also corresponds well to maximum hailstone sizes. A damage threshold could be identified for hailstone sizes around 2.5 cm (1 cm, based on the emergency response intensity (insurance claims. Emergency response intensity and claims costs both correlate positively with hailstone sizes. Higher claim costs also occurred in areas that experienced higher emergency response intensities.

  13. Factors influencing vaccination uptake. Workshop report. Current Australian research on the behavioural, social and demographic factors influencing immunisation, Royal Alexandra Hospital for Children, Sydney, March 1998. (United States)

    Forrest, J M; Burgess, M A; McIntyre, P B


    Current Australian research on factors influencing vaccination was discussed at a workshop held at the Royal Alexandra Hospital for Children, Sydney, in March 1998, sponsored by the National Centre for Immunisation Research and Surveillance of Vaccine Preventable Diseases (NCIRS). The application of decision making theory to vaccination behaviour, the expectations and experiences of mothers, and reasons why parents fail to vaccinate their children were considered. Mothers' perceptions of the risks of vaccines, preferences of parents and providers for the mode of vaccine delivery, and community and social factors were all found to be part of the framework within which vaccination is accepted in Australia. Consumer considerations, media influences and overseas comparisons were discussed.

  14. Legacy contaminant bioaccumulation in rock crabs in Sydney Harbour during remediation of the Sydney Tar Ponds, Nova Scotia, Canada. (United States)

    Walker, Tony R; MacAskill, Devin; Weaver, Peter


    Concentrations of PAHs, PCBs, metals and lipids in hepatopancreas of rock crabs (Cancer irroratus) were measured in Sydney Harbour (SH) for one year prior to remediation and three years of remediation of the Sydney Tar Ponds (STP), Nova Scotia. Low level concentrations of PCBs and metals were measured, although PAHs were mostly undetected. Metal concentrations showed little spatio-temporal variability, although highest concentrations of As, Cd and Cu were measured at reference stations furthest from the STP remediation site. Mercury concentrations were at least an order of magnitude lower than Canadian guidelines. Moderately elevated PCB concentrations were detected in crabs near Muggah Creek, but these were generally not higher than those measured during baseline. Despite remediation activities, current contaminant burdens measured in crabs were much lower than previously reported in other studies of crabs and lobster in industrial harbours in eastern Canada, due in part to natural recovery of SH sediments.

Health professional educators need to be responsive to health professionals' information and communication technological needs; however, there is a paucity of information about educators' attitudes to, and capabilities with, ICT. Methods: Fifty-two health professional educators, enrolled in health professional education postgraduate studies, participated in an online subject with specific eLearning components requiring the use of ICT. They completed a pre- and postquestionnaire pertaining to ICT attitudes, confidence, and usage. Results: Participants reported significant increases in overall ICT confidence during the subject despite it being high at baseline (mean: 7.0 out of 10; P=0.02. Even with increased ICT confidence, there were decreases in the participants' sense of ICT control when related to health professional education (P=0.002; whereas, the amount of time participants engaged with ICT devices was negatively correlated with the sense of ICT control (P=0.002. The effect of age and health discipline on ICT attitudes and confidence was not significant (P>0.05. Conclusion: This study reports that health professional educators have perceptual deficits toward ICT. The impact of eLearning increased confidence in ICT but caused a reduction in participants' sense of control of ICT. Health professional educators require more ICT training and support to facilitate better ICT integration in health professional education settings. Keywords: confidence, sense of control 

  16. Water Recycling in Australia

    Directory of Open Access Journals (Sweden)

    Ross Young


    Full Text Available Australia is the driest inhabited continent on earth and, more importantly, experiences the most variable rainfall of all the continents on our planet. The vast majority of Australians live in large cities on the coast. Because wastewater treatments plants were all located near the coast, it was thought that large scale recycling would be problematic given the cost of infrastructure and pumping required to establish recycled water schemes. This all changed when Australia experienced a decade of record low rainfall and water utilities were given aggressive targets to increase the volume of water recycled. This resulted in recycled water being accepted as a legitimate source of water for non-drinking purposes in a diversified portfolio of water sources to mitigate climate risk. To ensure community support for recycled water, Australia lead the world in developing national guidelines for the various uses of recycled water to ensure the protection of public health and the environment. Australia now provides a great case study of the developments in maximizing water recycling opportunities from policy, regulatory and technological perspectives. This paper explores the evolution in thinking and how approaches to wastewater reuse has changed over the past 40 years from an effluent disposal issue to one of recognizing wastewater as a legitimate and valuable resource. Despite recycled water being a popular choice and being broadly embraced, the concept of indirect potable reuse schemes have lacked community and political support across Australia to date.

  17. Distribution of inorganic and organic contaminants in sediments from Sydney Olympic Park and the surrounding Sydney metropolitan area. (United States)

    Ying, Guang-Guo; Rawson, Christopher A; Kookana, Rai S; Warne, Michael St J; Peng, Ping-An; Li, Xiao-Ming; Laginestra, Edwina; Tremblay, Louis A; Chapman, John C; Lim, Richard P


    Organic and inorganic contamination was assessed for sediments from wetlands and water bodies within the Sydney Olympic Park (SOP, remediated sites) and its surroundings (unremediated sites) and urban reference sites in the Sydney Basin. Among the seven elements analysed (As, Cd, Cr, Cu, Pb, Ni and Zn), Zn concentrations were the highest, followed by Pb, Cu and Cr in the sediments of SOP. Significantly higher concentrations (p 0.05) in concentrations were found for polycyclic aromatic hydrocarbons (PAHs) and polychlorinated biphenyls (PCBs) as well as DDTs between sediments from SOP and the urban reference sites. Source indicators suggest that PAHs in the sediments originated from combustion processes. Two distinct groups of dioxin profiles were observed within SOP and its surroundings. Levels of dioxins were more than 100 pg WHO-TEQ/g dry weight of sediment at five sites adjacent to the SOP boundaries. Based on the findings of the chemical profiles of the contaminants, the remediated sites in SOP can be regarded as similar to the urban reference sites within the Sydney Basin, while the adjacent unremediated sites have higher concentrations, especially of dioxins, that could still affect organisms in the aquatic environment.

  1. A spectral-based clustering for structural health monitoring of the Sydney Harbour Bridge (United States)

    Alamdari, Mehrisadat Makki; Rakotoarivelo, Thierry; Khoa, Nguyen Lu Dang


    This paper presents the results of a large scale Structural Health Monitoring application on the Sydney Harbour Bridge in Australia. This bridge has many structural components, and our work focuses on a subset of 800 jack arches under the traffic lane 7. Our goal is to identify which of these jack arches (if any) respond differently to the traffic input, due to potential structural damages or instrumentation issues. We propose a novel non-model-based method to achieve this objective, using a spectrum-driven feature based on the Spectral Moments (SMs) from measured responses from the jack arches. SMs contain information from the entire frequency range, thus subtle differences between the normal signals and distorted ones could be identified. Our method then applies a modified k-means- clustering algorithm to these features, followed by a selection mechanism on the clustering results to identify jack arches with abnormal responses. We performed an extensive evaluation of the proposed method using real data from the bridge. This evaluation included a control component, where the approach successfully detected jack arches with already known damage or issues. It also included a test component, which applied the method to a large set of nodes over a month of data to detect any potential anomaly. The detected anomalies turned out to have indeed system issues after further investigations.

    Full Text Available Abstract Background This paper examines rates of exposure to work-related violence and other trauma, and the prevalence of lifetime and current posttraumatic stress disorder (PTSD among female street-based sex workers. It also investigates associations between current PTSD symptoms and: demographic characteristics, psychiatric comorbidity, injecting and sex risk behaviours, and trauma history. Methods Cross sectional data collected from 72 women via face to face structured interviews. The interview included structured diagnostic assessment of DSM-IV PTSD; drug dependence; depression; experience of childhood trauma; and an assessment of sex working history. Results All but one of the women interviewed reported experiencing trauma, with the majority reporting multiple traumas that typically began in early childhood. Child sexual abuse, adult sexual assault and work related violence were commonly reported. Just under half of the women met DSM-IV criteria for PTSD and approximately one-third reported current PTSD symptoms. Adult sexual assault was associated with current PTSD symptoms. Depression and drug dependence were also highly prevalent; cocaine dependence in particular was associated with elevated rates of injecting risk and sexual risk behaviours. Conclusion These women reported complex trauma histories and despite ongoing opportunities for clinical intervention, they continued to experience problems, suggesting that current models of treatment may not be appropriate. More targeted interventions, and integrated mental health and drug treatment services are needed to address the problems these women are experiencing. Outreach services to these women remain a priority. Education strategies to reduce risky injecting and sexual behaviours among sex workers should also remain a priority.

  7. Fluid Flow History in Lower Triassic Bulgo Sandstone, Central Sydney Basin, Australia

    Institute of Scientific and Technical Information of China (English)


    The fluid flow history during diagenesis of the Lower Triassic Bulgo sandstone has been investigated through integrated analyses of petrography, stable isotope and fluid inclusion. Combined application of these techniques was intended to constrain the temperature, timing, chemistry and source of pore fluids during diagenetic cementation events in the Lower Triassic Bulgo sandstone. The dlagenesis proceeded in two different flow regimes: early dynamic fluid flow regime and late slow static fluid flow regime. The former was characterized by a slight increase of δ(18O) of pore waters form estimated -15 × 10-3 to -14 × 10-3 with the temperature increasing from ~ 10 ℃ to ~ 75 ℃. During early diagenesis, early clays and pore filling carbonates precipitated from the pore waters. The late slow flow/static fluid regime was characterized by a rapid 18O-enrichment process. δ(18O) of pore waters increased from -14× 10-3 to -5× 10-3 with the temperature increasing from 75 ℃ to 110 ℃. During the late diagenesis, kaolin (generation Ⅲ ), quartz and illite crystallized. Oil migrated to the sandstones of the Bulgo sandstone during quartz cementation.

  12. Fire effects on reservoir water quality: lessons from the 2013 Sydney wildfires (United States)

    Doerr, Stefan; Santin, Cristina; Chafer, Chris


    Unseasonally, early and severe forest fires burnt ca 10,000 ha of dry sclerophyl eucalypt forest in Oct. 2013 near Sydney (NSW, Australia). The fire affected parts of the Nepean catchment, which contributes to the greater Sydney water supply system. The spatial extent and severe nature of the burn raised concerns about the risk of water contamination from post-fire erosion. An investigation was launched with the aim to determine (i) the total loads of ash and loose charred topsoil that are particular susceptible to erosion, (ii) their chemical composition regarding constituents relevant to water quality, and (iii) the potential impacts of post-fire erosion events transferring some of this material into the reservoir. Sampling was carried out at a ridge in the Nepean catchment with a relatively homogeneous vegetation species composition, fuel load and soil characteristics, but with a range of burn severities, resulting from wind-driven differences in fire behaviour. This allowed sampling of three replicate sites each, with 30 sampling points each, for extreme, moderate-severe, and low burn severities, including also soil and litter sampling at a long-unburned control site. Burn severity was determined using the differenced normalised burn ratio (dNBR) obtained from satellite images immediately before (1 day) and after (1 week) the fire, validated by on site determination of fuel consumption completeness. Between the fire and the sampling campaign, rainfall was very limited so that there had been no significant redistribution of ash and loose charred topsoil by water erosion. The ash and loose charred topsoil were consistently wettable and the underlying uncharred soil highly water repellent at all sites and sampling points irrespective of burn severity. The total loads of ash and loose charred topsoil increased substantially with burn severity and changed in composition from comprising mainly charred litter and charcoal at low severity sites to charred litter

  15. A Critical Study of Stationary Energy Storage Policies in Australia in an International Context: The Role of Hydrogen and Battery Technologies

    Directory of Open Access Journals (Sweden)

    Jason Moore


    Full Text Available This paper provides a critical study of current Australian and leading international policies aimed at supporting electrical energy storage for stationary power applications with a focus on battery and hydrogen storage technologies. It demonstrates that global leaders such as Germany and the U.S. are actively taking steps to support energy storage technologies through policy and regulatory change. This is principally to integrate increasing amounts of intermittent renewable energy (wind and solar that will be required to meet high renewable energy targets. The relevance of this to the Australian energy market is that whilst it is unique, it does have aspects in common with the energy markets of these global leaders. This includes regions of high concentrations of intermittent renewable energy (Texas and California and high penetration rates of residential solar photovoltaics (PV (Germany. Therefore, Australian policy makers have a good opportunity to observe what is working in an international context to support energy storage. These learnings can then be used to help shape future policy directions and guide Australia along the path to a sustainable energy future.

    Pepler, Acacia S; Rakich, Clinton S, E-mail: [NSW Climate Services Section, Bureau of Meteorology PO Box 413, Darlinghurst, NSW 1300 (Australia)


    The Sydney catchment region encompasses over 16,000km{sup 2}, supplying water to over 4 million inhabitants. However, few studies have investigated the synoptic and climatic influences on inflow in this region, which are crucial for understanding the vulnerability of water supply in a changing climate. This study identifies extremely high and low inflow events between 1960 and 2008 based on catchment averages. The focus of the study is an analysis of the synoptic cause/s of each extreme inflow event. The events are evaluated to identify any trends and also to determine the concurrent significant climatic influences on rainfall over the catchments. Relationships between catchment inflow, rainfall, tropical SST indices, and other influencing factors such as observed wind and temperatures are investigated. Our results show that East Coast Lows and anomalously easterly flow are the drivers of high inflow events, with low inflow events dominated by westerly wind patterns and the El Nino-Southern Oscillation.

    Full Text Available Abstract Background Complementary and alternative medicine (CAM is common in patients with chronic disease such as diabetes mellitus. The primary objective of the study was to determine the overall prevalence and type of CAM use in individuals with diabetes mellitus (DM in Western Sydney and to compare the prevalence and factors associated with CAM use with the literature. Methods A multicenter cross-sectional study was undertaken using a self-completed questionnaire distributed to patients with DM attending a public hospital and specialist endocrinology clinics in the region. The type of DM and pattern of CAM utilisation were analyzed. Results Sixty nine people responded to the questionnaire: age range of 18-75 years during a twelve week collection period. Overall, 32 respondents with diabetes were using some form of CAM, resulting in a utilisation rate of 46.3%. Twenty of the 32 CAM users used CAM specifically to treat their diabetes accounting for 28.9% of the respondent sample population. Multivitamins (40%, cinnamon, Co-enzyme q10 and prayer were the most frequently used CAM modalities. There was no significant difference between males and females, age range, income or diabetes complications between CAM and non-CAM users. (p values each > 0.05 The factor most significantly associated with CAM usage was being born overseas (p = 0.044. Conclusions Almost half the respondents (46.3% used CAM: 28% used CAM specifically to treat their diabetes. Individuals born overseas were significantly more likely to use CAM than those born in Australia. Other factors such as age, gender, wealth and duration of living with diabetes were not associated with higher rate of CAM usage.

  19. Understanding extreme rainfall events in Australia through historical data (United States)

    Ashcroft, Linden; Karoly, David John


    Historical climate data recovery is still an emerging field in the Australian region. The majority of Australia's instrumental climate analyses begin in 1900 for rainfall and 1910 for temperature, particularly those focussed on extreme event analysis. This data sparsity for the past in turn limits our understanding of long-term climate variability, constraining efforts to predict the impact of future climate change. To address this need for improved historical data in Australia, a new network of recovered climate observations has recently been developed, centred on the highly populated southeastern Australian region (Ashcroft et al., 2014a, 2014b). The dataset includes observations from more than 39 published and unpublished sources and extends from British settlement in 1788 to the formation of the Australian Bureau of Meteorology in 1908. Many of these historical sources provide daily temperature and rainfall information, providing an opportunity to improve understanding of the multidecadal variability of Australia's extreme events. In this study we combine the historical data for three major Australian cities - Melbourne, Sydney and Adelaide - with modern observations to examine extreme rainfall variability over the past 174 years (1839-2013). We first explore two case studies, combining instrumental and documentary evidence to support the occurrence of severe storms in Sydney in 1841 and 1844. These events appear to be at least as extreme as Sydney's modern 24-hour rainfall record. Next we use a suite of rainfall indices to assess the long-term variability of rainfall in southeastern Australia. In particular, we focus on the stationarity of the teleconnection between the El Niño-Southern Oscillation (ENSO) phenomenon and extreme rainfall events. Using ENSO reconstructions derived from both palaeoclimatic and documentary sources, we determine the historical relationship between extreme rainfall in southeastern Australia and ENSO, and examine whether or not this

  1. Late HIV diagnosis of people from culturally and linguistically diverse backgrounds in Sydney: the role of culture and community. (United States)

    Körner, H


    In Australia more than 85% of newly diagnosed HIV infections in 1999-2003 were homosexually acquired. In contrast, among people from culturally and linguistically diverse backgrounds, there is a much higher proportion of heterosexual exposure and many of the heterosexually acquired infections are diagnosed 'late', with people sometimes presenting with symptoms of AIDS. This paper reports on circumstances of late HIV diagnosis, meaning of an HIV-positive diagnosis and perceptions of risk among HIV-positive people from a variety of cultural and ethnic backgrounds in Sydney. The focus was on commonalities across cultures and ethnicities. Data were collected through semi-structured in-depth interviews with clients of the Multicultural HIV/AIDS and Hepatitis C Service and a sexual health clinic. Regular HIV tests were the exception in this group. Testing was usually motivated by a serious health crisis. Participants interpreted their diagnosis in the context of their knowledge and experiences with HIV/AIDS in their country of birth and the perceptions of HIV/AIDS in their ethnic communities in Australia. Many were not aware of the relationship between HIV and AIDS. Risk was perceived in terms of 'risk group' membership not in terms of practices and behaviours. Late diagnosis cannot be explained solely by association with country of birth, race or ethnicity. Rather, it is located within complex sets of social and cultural relations: the values attributed to HIV/AIDS and those infected and the social and cultural relations of ethnic communities in Australia and the dominant culture. These are enacted in healthcare seeking behaviour, perceptions of people with HIV and perceptions of being 'at risk'.

  2. Nucleopolyhedrovirus Introduction in Australia

    Patrick Buerger; Caroline Hauxwell; David Murray


    Nucleopolyhedrovirus (NPV) has become an integral part of integrated pest management (IPM) in many Australian agricultural and horticultural crops. This is the culmination of years of work conducted by researchers at the Queensland Department of Primary Industries and Fisheries (QDPI&F) and Ag Biotech Australia Pty Ltd. In the early 1970's researchers at QDPI&F identified and isolated a virus in Helicoverpa armigera populations in the field. This NPV was extensively studied and shown to be highly specific to Helicoverpa and Heliothis species. Further work showed that when used appropriately the virus could be used effectively to manage these insects in crops such as sorghum, cotton, chickpea and sweet corn. A similar virus was first commercially produced in the USA in the 1970's. This product, Elcar(R), was introduced into Australia in the late 1970's by Shell Chemicals with limited success. A major factor contributing to the poor adoption of Elcar was the concurrent enormous success of the synthetic pyrethroids. The importance of integrated pest management was probably also not widely accepted at that time. Gradual development of insect resistance to synthetic pyrethroids and other synthetic insecticides in Australia and the increased awareness of the importance of IPM meant that researchers once again turned their attentions to environmentally friendly pest management tools such NPV and beneficial insects. In the 1990's a company called Rhone-Poulenc registered an NPV for use in Australian sorghum, chickpea and cotton. This product, Gemstar(R), was imported from the USA. In 2000 Ag Biotech Australia established an in-vivo production facility in Australia to produce commercial volumes of a product similar to the imported product. This product was branded, ViVUS(R), and was first registered and sold commercially in Australia in 2003. The initial production of ViVUS used a virus identical to the American product but replicating it in an Australian Helicoverpa

  4. Responding to a measles outbreak in a Pacific island community in western Sydney: community interviews led to church-based immunization clinics

    Directory of Open Access Journals (Sweden)

    Nicola Scott


    Full Text Available Introduction: There are large Pacific island communities in western and south-western Sydney, New South Wales, Australia. In 2011 and 2012, measles outbreaks disproportionally affected children and youth within these communities. The objectives of this study were to explore barriers to immunization in a Pacific island community from the perspectives of community members and health professionals and to conduct a pilot programme whereby immunization catch-up clinics were held in a Samoan church in western Sydney. Methods: Interviews were conducted with Pacific island community members (N = 12 and health professionals connected with the Pacific island community (N = 7 in 2013. A partnership with a local Samoan church was established to provide an accessible venue for immunization catch-up clinics. Results: Among the community members there were high levels of belief in the importance of immunization and a positive view regarding the protection offered by immunization. A key barrier reported by community members was being busy and therefore having limited time to get children immunized. The important role of the church within the community was emphasized in the interviews, and as a result, two immunization catch-up clinics were held in a Samoan church in western Sydney. The age range of attendees was 7–33 years. A total of 31 measles, mumps and rubella doses and 19 meningococcal C doses were given during the two clinics. Discussion: The outcomes of the interviews and the subsequent clinics highlighted the potential of churches as a venue for providing public health interventions such as catch-up immunization.

  5. Pieces of a thousand stories: repatriation of the history of Aboriginal Sydney

    Directory of Open Access Journals (Sweden)

    Peter Read


    Full Text Available The on-line project A History of Aboriginal Sydney, based at the University of Sydney, takes existing educational and Australian Indigenous digital initiatives in a new direction. By dividing Sydney into six geographical areas, we are creating a knowledge base of post-invasion Aboriginal history, incorporating different forms of tagging, timeline and digital mapping to provide multiple paths to information in text, videos, still images and, in the future, three dimensional reconstructions of former living areas. After eighteen months research we are maintaining a balance between unearthing new and forgotten material, incorporating it into our developing database, and exploring the potential of digital mapping, animation and 3D historical reconstruction for educational and research purposes. With close Indigenous consultation, especially the Aboriginal Educational Consultative Groups, we hope to digitally construct the Aboriginal history of Sydney and return it to the people who have been deprived of so much of their history for so long.

  8. Edinburgh and its role in the foundation of Sydney Medical School. (United States)

    Walker-Smith, J


    In 1882, Thomas Anderson Stuart (1856-1920) was appointed as Foundation Professor of Physiology and Anatomy at the University of Sydney. At the time he was Assistant-Professor of Physiology in the University of Edinburgh. He initiated the building of the Sydney Medical School in Scottish Tudor Gothic style. He attracted notable figures to Sydney Medical School, such as Dr Robert Scot Skirving. The original medical school (now the Anderson Stuart Building) continues today as the pre-clinical medical school of the University of Sydney. Its stained glass windows and many busts of distinguished figures in the history of medicine are a constant reminder of the history of medicine. The building with its gothic architecture and echoes of northern Britain has given generations of Sydney medical students a powerful message, that they were part of an ancient and noble profession. The recruitment of Edinburgh academics to Sydney ended with Professor CG Lambie who retired in 1956. The 1950s were a watershed between the Edinburgh heritage and the Australian future.

  11. Factors affecting consumer's continued use of internet banking: Empirical Evidence from Australia

    Directory of Open Access Journals (Sweden)

    Sujana Adapa


    Full Text Available The goal of this study was to investigate the factors that influence consumers continued use of internet banking in Australia. Patterns of continued use of internet banking have been neglected as most of the existing studies focus on either consumer adoption or acceptance of internet banking. However, in comparison to new customer acquisition, measures of continued use of internet banking are important as it is related to a cost-effective marketing strategy aimed at retaining customers. The present study is a response to a gap in existing literature which requires the application of more integrated theory testing and the identification of factors that influence the continued use of internet banking in order of importance to consumers. The study sets out to develop a conceptual framework based on theoretical models related to the acceptance of technology and diffusion of innovations theory. The conceptual model developed encompasses technology, channel, social and value for money factors as predictors in the identification of influential factors for consumers and their continued use of internet banking. Data were collected using a cross-sectional mall intercept survey in the Western Sydney region, comprising a sample of 372 internet banking users. After testing the data for accuracy, exploratory factor analysis was performed for factor clarification on five key scales related to the use of internet banking service delivery based on technology, channel, social, value for money and continued use factors. The final components that emerged were employed in hierarchical multiple regression analyses to test the proposed framework. Value for money, channel and technology factors was found, in that order, to be influential in predicting consumers’ continued and frequent use of internet banking.

  13. Melbourne versus Sydney: semiotic reflections on first and second cities.

    Directory of Open Access Journals (Sweden)

    Massimo Leone


    Full Text Available Urban marketing has recently been adopting the concept, and the label, of “second city”. However, this concept requires sharper theoretical definition in order to turn heuristic. Thus far, it has been conceived in relation to an “ideology of ranking”, strictly related to the worldview of post-modern globalization. A more fruitful definition of “second cities” results from Charles S. Peirce’s idea of secondness: a city is second to another not in quantitative, but in qualitative and relational terms. The semiotic model of Jurij M. Lotman offers a suitable methodology to analyse this relational definition, as it is exemplified by the case-study of the rivalry between Melbourne and Sydney. A historical survey of their relation shows that the latter progressively embraced an identity of “secondness” so as to successfully market an alternative vision of urban life. Melbourne therefore provides a model for non-quantitative construction of urban distinctiveness.

  14. Implementation of an environmental management system (EMS) at Sydney Electricity

    Energy Technology Data Exchange (ETDEWEB)

    Markus, T. [Sydney Electricity, Sydney, NSW (Australia)


    Implementation of an environmental management system (EMS) to a recognised standard and having it certified externally is a means of demonstrated to the community, to customers and to the regulatory agencies, a determination to care for the environment. This paper outlines the EMS developed by Sydney Electricity. The project to develop the EMS comprised two stages. The first consisted of the preparation of a Preparatory Environmental Review, and the second, the implementation stage. The general elements of the EMS and a description of the details of the implementation are included. The continuing suitability and effectiveness of the EMS will depend on the commitment from management, continuing public consultation, technical documentation preparation and dissemination, employee motivation, training and assessment, and regular management and audit reviews. The EMS is expected to enable the verification of performance against targets, assist auditing and corrective action, control all activities for minimum adverse effect and demonstrate due diligence to the regulatory agencies. It is also expected to facilitate compliance with legislation and with policy. 1 fig.

    We demonstrate a novel technology that combines the power of the multi-object spectrograph with the spatial multiplex advantage of an integral field spectrograph (IFS). The Sydney-AAO Multi-object IFS (SAMI) is a prototype wide-field system at the Anglo-Australian Telescope (AAT) that allows 13 imaging fibre bundles ("hexabundles") to be deployed over a 1-degree diameter field of view. Each hexabundle comprises 61 lightly-fused multimode fibres with reduced cladding and yields a 75 percent filling factor. Each fibre core diameter subtends 1.6 arcseconds on the sky and each hexabundle has a field of view of 15 arcseconds diameter. The fibres are fed to the flexible AAOmega double-beam spectrograph, which can be used at a range of spectral resolutions (R=lambda/delta(lambda) ~ 1700-13000) over the optical spectrum (3700-9500A). We present the first spectroscopic results obtained with SAMI for a sample of galaxies at z~0.05. We discuss the prospects of implementing hexabundles at a much higher multiplex over wid...

  16. Chemical fingerprinting of gasoline. Part 3. Comparison of unevaporated automotive gasoline samples from Australia and New Zealand. (United States)

    Sandercock, P M L; Du Pasquier, E


    A gas chromatography-mass spectrometry with selected ion monitoring (GC-MS (SIM)) method was used to discriminate samples of unevaporated gasoline collected from Auckland, New Zealand and Sydney, Australia. This method was applied to 28 samples of unevaporated gasoline, covering three different grades (regular unleaded, premium unleaded and premium plus unleaded), that were collected from service stations in Auckland, New Zealand in summer (February) and winter (August). The 14 samples of summer gasoline collected in New Zealand could be divided into seven unique groups. The 14 samples of winter gasoline from New Zealand could be divided into 14 unique groups. The 14 samples collected in New Zealand during February 2002 were then compared to 24 samples of unevaporated gasoline collected from service stations in Sydney, Australia during the same month. Most of the samples could be differentiated based on their country of origin.

  17. Surveillance of Space in Australia (United States)

    Newsam, G.

    Australia's geography and technology base got it off to a flying start in the early days of surveillance of space, starting with CSIRO's first radio telescope in the 1940's and climaxing in NASA's establishment of station 43 in the Deep Space Network at Tidbinbilla in 1965. But Britain's exit from space and the subsequent closure of the Woomera launch range and associated space tracking facilities in the early 1970's saw the start of a long draw-down of capability. Programs such as CSIRO's radio astronomy telescopes, Electro-Optic Systems' adoption of laser technology for satellite laser ranging and tracking system, and the exploration of the use of technology developed in Australia's over-the-horizon-radar program for surveillance of space, kept some interest in the problem alive, but there has been no serious national investment in the area for the last thirty years. Recently, however, increased awareness of the vulnerability of space systems and the need to include potential opponents' space capabilities in operations planning has led to a revival of interest in space situational awareness within the Australian Defence Organisation. While firm commitments to new systems must wait on the next Defence White Paper due out at the end of 2007 and the policy directions it formally endorses, discussions have already started with the US on participating in the Space Surveillance Network (SSN) and developing a comprehensive space situational awareness capability. In support of these initiatives the Defence Science and Technology Organisation (DSTO) is drawing up an inventory of relevant Australian capabilities, technologies and activities: the paper will describe the findings of this inventory, and in particular local technologies and systems that might be deployed in Australia to contribute to the SSN. In the optical regime the available options are rather limited; they centre primarily on the satellite laser ranging technology developed by Electro-Optic Systems and

  18. Vaccination against hepatitis A and B in persons subject to homelessness in inner Sydney: vaccine acceptance, completion rates and immunogenicity. (United States)

    Poulos, Roslyn G; Ferson, Mark J; Orr, Karen J; McCarthy, Michele A; Botham, Susan J; Stern, Jerome M; Lucey, Adrienne


    To determine acceptance, completion rates and immunogenicity of the standard vaccination schedule for hepatitis A (HAV) and B (HBV) in persons subject to homelessness. A convenience sample of clients (n=201) attending a medical clinic for homeless and disadvantaged persons in Sydney was enrolled. Serological screening for HAV and HBV was undertaken. An appropriate vaccination program was instituted. Post-vaccination serology determined serological response. Although many clients had serological evidence of past infection, at least 138 (69%) clients had the potential to benefit from vaccination. For hepatitis A and B vaccinations, completion rates were 73% (73 of 100 clients) and 75% (69 of 92 clients), respectively; after vaccination, protective antibody was found in 98.2% (56 of 57) and 72% (36 of 50) of clients, respectively. A successful vaccination program can be mounted with a vulnerable population. We consider a clinic with a well-established history of acceptance and utilisation by the target group; a low staff turnover and regular clientele; inclusion of vaccination as part of routine client care; and counselling (part of pre- and post-serological testing) essential components in achieving good vaccination completion rates. © 2010 The Authors.

  20. Elucidating the life cycle of Marteilia sydneyi, the aetiological agent of QX disease in the Sydney rock oyster (Saccostrea glomerata). (United States)

    Adlard, Robert D; Nolan, Matthew J


    Marteilia sydneyi (Phylum Paramyxea, Class Marteiliidea, Order Marteiliida) (the causative agent of QX disease) is recognised as the most severe parasite to infect Saccostrea glomerata, the Sydney rock oyster, on the east coast of Australia. Despite its potential impact on industry (>95% mortality), research towards lessening these effects has been hindered by the lack of an experimental laboratory model of infection as a consequence of our incomplete understanding of the life cycle of this parasite. Here, we explored the presence of this parasite in hosts other than a bivalve mollusc from two study sites on the Hawkesbury River, New South Wales, Australia. We employed PCR-based in situ hybridisation and sequence analysis of a portion of the first internal transcribed spacer of rDNA in an attempt to detect M. sydneyi DNA in 21 species of polychaete worm. Marteilia DNA was detected in 6% of 1247 samples examined by PCR; the analysis of all amplicons defined one distinct sequence type for first internal transcribed spacer, representing M. sydneyi. Of the polychaete operational taxonomic units test-positive in PCR, we examined 116 samples via in situ hybridisation DNA probe staining and identified M. sydneyi DNA in the epithelium of the intestine of two specimens of Nephtys australiensis. Two differing morphological forms were identified: a 'primordial' cell that contained a well-defined nucleus but had little differentiation in the cytoplasm, and a 'plasmodial' cell that showed an apparent syncytial structure. This finding represents the first known record of the identification of M. sydneyi being parasitic in an organism other than an oyster, and only the third record of any species of Marteilia identified from non-molluscan hosts. Future work aims at determining if N. australiensis and S. glomerata are the only hosts in the life cycle of this paramyxean, and the development of experimental models to aid the production of QX disease-resistant oysters.

  1. The Sydney Diabetes Prevention Program: A community-based translational study

    Directory of Open Access Journals (Sweden)

    Farrell Louise


    Full Text Available Abstract Background Type 2 diabetes is a major public health problem in Australia with prevalence increasing in parallel with increasing obesity. Prevention is an essential component of strategies to reduce the diabetes burden. There is strong and consistent evidence from randomised controlled trials that type 2 diabetes can be prevented or delayed through lifestyle modification which improves diet, increases physical activity and achieves weight loss in at risk people. The current challenge is to translate this evidence into routine community settings, determine feasible and effective ways of delivering the intervention and providing on-going support to sustain successful behavioural changes. Methods/Design The Sydney Diabetes Prevention Program (SDPP is a translational study which will be conducted in 1,550 participants aged 50-65 years (including 100 indigenous people aged 18 years and older at high risk of future development of diabetes. Participants will be identified through a screening and recruitment program delivered through primary care and will be offered a community-based lifestyle modification intervention. The intervention comprises an initial individual session and three group sessions based on behaviour change principles and focuses on five goals: 5% weight loss, 210 min/week physical activity (aerobic and strength training exercise, limit dietary fat and saturated fat to less than 30% and 10% of energy intake respectively, and at least 15 g/1000 kcal dietary fibre. This is followed by 3-monthly contact with participants to review progress and offer ongoing lifestyle advice for 12 months. The effectiveness and costs of the program on diabetes-related risk factors will be evaluated. Main outcomes include changes in weight, physical activity, and dietary changes (fat, saturated fat and fibre intake. Secondary outcomes include changes in waist circumference, fasting plasma glucose, blood pressure, lipids, quality of life

  2. Western Sydney is hot! Community arts and changing perceptions of the West

    Directory of Open Access Journals (Sweden)

    Christina Ho


    Full Text Available Can the arts change how we view cities? How can we evaluate the broad social impacts of arts programs, particularly in elusive areas such as the local image of urban communities? This article examines the cultural renaissance of Western Sydney, long considered a crass, working-class cultural wasteland. In the last two decades, the region has experienced a proliferation of new artistic initiatives, and advocates now hail Sydney’s West as the true face of multicultural Australia’s cultural vitality. This article also documents how community arts and development programs have contributed to these shifting perceptions, analysing these contributions in terms of social impact evaluation. It argues that evaluating social impact expands the parameters of conventional evaluation techniques, which typically focus on program-level outputs and outcomes. It presents a case study of a Western Sydney community organisation, Information and Cultural Exchange (ICE, which, for 20 years, has delivered community cultural development and professional development programs for Western Sydney artists. Engaging with historically disadvantaged communities, the organisation has specialised in art forms that have resonated with the region, including hip hop, digital storytelling, and filmmaking, and in the process has played a key role in re-imagining Western Sydney as a cutting edge, multicultural hub of creative vibrancy.

  3. Emergence of the GII-4 Norovirus Sydney2012 strain in England, winter 2012-2013.

    Directory of Open Access Journals (Sweden)

    David J Allen

    Full Text Available Norovirus is the commonest cause of acute gastrointestinal disease and is the main aetiological agent of outbreaks of gastroenteritis, particularly in semi-closed environments. Norovirus infections in England typically peak between December and March each year. The most commonly detected norovirus strains belong to the genetically diverse genogroup-II genotype-4 (GII-4 genocluster and in the previous two norovirus winter seasons the majority of GII-4 strains in circulation worldwide have been genetically similar to the GII-4 strain New Orleans 1805/2009/USA. At the beginning of the 2012/13 season a genetically distinct GII-4 strain (Sydney 2012/NSW0514/2012/AU was described which emerged worldwide during the winter of 2012/13. Here we describe the emergence of norovirus strains genetically related to Sydney2012 in England during the 2012/13 season to replace NewOrleans2009 strains as the most commonly detected variant of GII-4 norovirus in England. Furthermore, we demonstrate that whilst the emergence of Sydney2012 coincided with an early peak in the number of norovirus outbreaks, there was not an overall increase in norovirus activity compared to the previous season. Finally, we show that the Sydney2012 strain is associated with distinct genetic changes compared to the NewOrleans2009 strain, and these changes may have contributed to the emergence of the Sydney2012 strain.

  4. An audit of food and beverage advertising on the Sydney metropolitan train network: regulation and policy implications. (United States)

    Sainsbury, Emma; Colagiuri, Stephen; Magnusson, Roger


    Increased marketing of energy-dense, nutrient-poor foods has been identified as a driver of the global obesity epidemic and a priority area for preventative efforts. Local and international research has focused on the unhealthiness of television advertising, with limited research into the growing outdoor advertising industry. This study aimed to examine the extent of food and beverage advertising on the Sydney metropolitan train network, and to assess the nutritional quality of advertised products against the Australian Guide to Healthy Eating. All 178 train stations on the Sydney metropolitan train network were surveyed in summer and winter. A survey tool was developed to collect information for all advertisements on and immediately surrounding the train station. Information included product, brand, location and advertisement format. Advertisements were coded by nutrition category, product subcategory and size. Chi-square, ANOVA and ANCOVA tests were conducted to test for differences in the amount of food and beverage advertising by season and area socioeconomic status (SES). Of 6931 advertisements identified, 1915 (27.6%) were promoting a food or beverage. The majority of food and beverage advertisements were for unhealthy products; 84.3% were classified as discretionary, 8.0% core and 7.6% miscellaneous. Snack foods and sugar-sweetened beverages were the most frequently advertised products, regardless of season. Coca-Cola and PepsiCo were the largest advertisers on the network, contributing 10.9% and 6.5% of total advertisements respectively. There was no difference in the mean number of food and beverage advertisements by area SES, but the proportion of advertising that was for discretionary foods was highest in low SES areas (41.9%, p train network are overwhelmingly for unhealthy (discretionary) products. The results of this study highlight the inadequacy of Australia's voluntary self-regulatory system in protecting members of the public from exposure to

  16. Using the VegeSafe community science program to measure, evaluate risk and advise on soil-metal contamination in Sydney backyards (United States)

    Taylor, M. P.; Rouillon, M.; Harvey, P.; Kristensen, L. J.; Steven, G. G.


    The extent of metal contamination in Sydney residential garden soils was evaluated using data collated from a 3-year university community science program called VegeSafe. Despite knowledge of industrial and urban contamination amongst scientists, the general public remains under informed about the potential risks of exposure from legacy contaminants in their home environments. The Australian community was offered free soil metal screening allowing access to soil samples for research purposes. Participants followed specific soil sampling instructions and posted samples to the University for analysis with a field portable X-ray Fluorescence (pXRF) spectrometer. Over the 3-year period >5000 soil samples were collected and analysed from >1000 households across Australia, primarly from vegetable gardens. As anticipated, the primary soil metal of concern was lead: mean concentrations were 413 mg/kg (front garden), 707 mg/kg (drip line), 226 mg/kg (back yard) and 301 mg/kg (vegetable garden). The Australian soil lead guideline of 300 mg/kg for residential yards was exceeded at 40% of domestic properties. Soil lead concentrations >1000 mg/kg were identified in 15% of Sydney backyards. The incidence of highest soil lead contamination was greatest in the inner city area with concentrations declining towards background values of 20-30 mg/kg at 30-40 km distance from the city. Community engagement with VegeSafe participants has resulted in useful outcomes: dissemination of knowledge related to contamination legacies and health risks, owners building raised beds containing clean soil, and, in numerous cases owners replacing their contaminated soil. This study demonstrates the potential for similar community science programs for expediting mass sample collection of soils and dusts for analysis of traditional and emerging contaminants within the home environment.

  17. Middle Permian paleomagnetism of the Sydney Basin, Eastern Gondwana: Testing Pangea models and the timing of the end of the Kiaman Reverse Superchron (United States)

    Belica, M. E.; Tohver, E.; Pisarevsky, S. A.; Jourdan, F.; Denyszyn, S.; George, A. D.


    Paleomagnetic and geochronologic data from the eastern margin of Gondwana have been obtained from the Gerringong Volcanics in the southern Sydney Basin, Australia. The corresponding paleomagnetic pole at 56.9°S, 154.8°E (N = 131; A95 = 9.1°) has a 40Ar/39Ar plagioclase plateau age of 265.05 ± 0.35 [0.46] Ma from the Bumbo Latite, and overlaps with recent radio-isotopic and paleomagnetic results published from Western Gondwana. The long-documented inconsistency between Middle Permian Eastern and Western Gondwanan paleomagnetic datasets is most likely an artefact of a lack of reliable paleomagnetic data from Eastern Gondwana for this period. A number of well-dated and recently published ca. 265 Ma paleomagnetic results from Gondwana and Laurussia are shown to be consistent with the Wegenerian Pangea A configuration, with a loose N-S fit of the continents for the Middle Permian. The lack of crustal overlap negates the need for a Pangea B configuration, which if valid must have been assembled to Pangea A by ca. 265 Ma. The reverse polarity Bumbo Latite was sampled from the Kiaman type-section located in the southern Sydney Basin. Three cases of normal polarity were detected in the overlying Saddleback, Dapto, and Berkeley Latites, previously assigned to the Kiaman Reverse Superchron (KRS). We review KRS-aged magnetostratigraphic data and propose that an age assignment of 265 Ma most likely represents the termination of the non-reversing field, with longer stable intervals of normal polarity recorded and able to be correlated globally.

  19. The 'Sydney Principles' for reducing the commercial promotion of foods and beverages to children. (United States)

    Swinburn, Boyd; Sacks, Gary; Lobstein, Tim; Rigby, Neville; Baur, Louise A; Brownell, Kelly D; Gill, Tim; Seidell, Jaap; Kumanyika, Shiriki


    A set of seven principles (the 'Sydney Principles') was developed by an International Obesity Taskforce (IOTF) Working Group to guide action on changing food and beverage marketing practices that target children. The aim of the present communication is to present the Sydney Principles and report on feedback received from a global consultation (November 2006 to April 2007) on the Principles. The Principles state that actions to reduce marketing to children should: (i) support the rights of children; (ii) afford substantial protection to children; (iii) be statutory in nature; (iv) take a wide definition of commercial promotions; (v) guarantee commercial-free childhood settings; (vi) include cross-border media; and (vii) be evaluated, monitored and enforced. The draft principles were widely disseminated and 220 responses were received from professional and scientific associations, consumer bodies, industry bodies, health professionals and others. There was virtually universal agreement on the need to have a set of principles to guide action in this contentious area of marketing to children. Apart from industry opposition to the third principle calling for a statutory approach and several comments about the implementation challenges, there was strong support for each of the Sydney Principles. Feedback on two specific issues of contention related to the age range to which restrictions should apply (most nominating age 16 or 18 years) and the types of products to be included (31% nominating all products, 24% all food and beverages, and 45% energy-dense, nutrient-poor foods and beverages). The Sydney Principles, which took a children's rights-based approach, should be used to benchmark action to reduce marketing to children. The age definition for a child and the types of products which should have marketing restrictions may better suit a risk-based approach at this stage. The Sydney Principles should guide the formation of an International Code on Food and Beverage

  20. Monitoring effects of remediation on natural sediment recovery in Sydney Harbour, Nova Scotia. (United States)

    Walker, Tony R; Macaskill, Devin; Rushton, Theresa; Thalheimer, Andrew; Weaver, Peter


    Chemical contaminants were assessed in Sydney Harbour, Nova Scotia during pre-remediation (baseline) and 3 years of remediation of a former coking and steel facility after nearly a century of operation and historical pollution into the Sydney Tar Ponds (STP). Concentrations of polycyclic aromatic hydrocarbons (PAHs), polychlorinated biphenyls, metals, and inorganic parameters measured in sediments and total suspended solids in seawater indicate that the overall spatial distribution pattern of historical contaminants remains unchanged, although at much lower concentrations than previously reported due to natural sediment recovery, despite remediation activities. Measured sediment deposition rates in bottom-moored traps during baseline were low (0.4-0.8 cm year(-1)), but during dredging operations required for construction of new port facilities in the inner Sydney Harbour, sedimentation rates were equivalent to 26-128 cm year(-1). Measurements of sediment chemical contaminants confirmed that natural recovery rates of Sydney Harbour sediments were in broad agreement with predicted concentrations, or in some cases, lower than originally predicted despite remediation activities at the STP site. Overall, most measured contaminants in sediments showed little temporal variability (4 years), except for the detection of significant increases in total PAH concentrations during the onset of remediation monitoring compared to baseline. This slight increase represents only a short-term interruption in the overall natural recovery of sediments in Sydney Harbour, which were enhanced due to the positive impacts of large-scale dredging of less contaminated outer harbor sediments which were discharged into a confined disposal area located in the inner harbor.

  1. Quantifying the Reduction in Water Demand due to Rainwater Tank Installations at Residential Properties in Sydney

    Directory of Open Access Journals (Sweden)

    Danious P. Sountharajah


    Full Text Available This paper examines data on actual reductions in consumption of water supply due to the widespread installation of rainwater tanks at residential properties in the Sydney metropolitan area and surrounding areas connected to Sydney Water Corporation water supply mains. The water consumption was based on metered potable water usage between 2002 and 2009. The number of properties in the study database totalled 962,697 single residential dwellings. Of this a total of 52,576 or 5.5% of Sydney’s households had a rainwater tank registered with Sydney Water Corporation.  The water usage consumption before and after the installation of the rainwater tank was analysed to quantify the extent to which rainwater tanks reduced mains water consumption. The average percentage of water savings by installing rainwater tanks across all 44 local government authorities was 9%. In some Sydney localities this reduction was up to 15%. On average, a household was able to save around 24 kilolitre of water annually by installing a rainwater tank even without considering other factors that affect water usage. The results were compared against socio-demographic factors using variables such as household size, educational qualifications, taxable income, rented properties, and non-English-speaking background, etc. to gain an appreciation of how these factors may have influenced the outcomes evident in the data. Among the co-relations found were that most properties within inner Sydney with a rainwater tank achieved at least a 9 to 11% additional reduction in water usage, with more than half of those local government authorities achieving more than 11%; properties with larger land area were more likely to have a rainwater tank installed; local government authorities with more people born in non-English speaking countries had lower reduction in water consumption reductions. 

  2. One confirmed and one suspected case of pharyngeal gonorrhoea treatment failure following 500mg ceftriaxone in Sydney, Australia. (United States)

    Read, Phillip J; Limnios, E Athena; McNulty, Anna; Whiley, David; Lahra, Monica M


    Emerging antimicrobial resistance within Neisseria gonorrhoeae (NG) is a significant global public health threat. Detection and investigation of treatment failures is a crucial component of the World Health Organisation's response to this challenge. We report the cases of two homosexual men, both treated for pharyngeal NG with 500mg intramuscular ceftriaxone, in whom a test of cure 1 week after treatment showed persisting infection. Both men denied further sexual activity. In the first case, treatment failure was confirmed, since the isolates before and after treatment were identical by auxotype, antibiogram, multilocus sequence type (MLST) and multi-antigen sequence type (NG-MAST). In the second case, the MLSTs before and after treatment were identical, but NG-MAST results were similar but not indistinguishable. These cases underline the importance of test-of-cure and molecular investigations in identifying treatment failure, but also highlight the complexity of distinguishing treatment failure from reinfection when relying on highly variable molecular targets that may be subject to drug pressure.

  5. The effect of methamphetamine and heroin price on polydrug use: A behavioural economics analysis in Sydney, Australia. (United States)

    Chalmers, Jenny; Bradford, Deborah; Jones, Craig


    A key aim of supply-side drug law enforcement is to reduce drug use by increasing the retail price of drugs. Since most illicit drug users are polydrug users the effectiveness of this strategy depends on the extent to which drug users reduce their overall consumption of drugs. The literature shows that drug users do reduce their consumption of a drug when its price increases. However the extent of that decrease and the implications for the use of other drugs vary across studies. A sample of 101 Australian methamphetamine users was surveyed using a behavioural economics approach. Participants were given a hypothetical fixed drug budget, presented with a range of drug price lists and asked how many units of each drug they would purchase. Methamphetamine and heroin prices were varied independently across trials. While demand for both methamphetamine and heroin was found to be price elastic, elasticity estimates were influenced by the nature of participants' drug dependence. The group least responsive to changes in methamphetamine price were those dependent only on methamphetamine, while the group most responsive were dependent only on heroin. Similar findings emerged in relation to changes in heroin price. Cross-price elasticity analysis showed limited substitution into other drugs as the price of methamphetamine increased. In contrast, for heroin, there was significant substitution into pharmaceutical opioids and to a lesser extent, benzodiazepines and methamphetamine. However, for the most part, the decreases in methamphetamine or heroin consumption outweighed any substitution into other drugs. The reduction in overall drug consumption and expenditure in response to price increases in heroin and methamphetamine observed in this sample lend support to supply-side enforcement strategies that aim to increase retail drug price. Notably, this analysis highlights the importance of accounting for the nature of users' drug dependence in estimating price responsiveness. Copyright 2010 Elsevier B.V. All rights reserved.

  7. Comparison of stream macroinvertebrate assemblages in canyon ecosystems of the Blue Mountains (Australia) with and without recreational traffic: a pilot study in impossible terrain


    Hardiman, Nigel


    In Australia, the adventure sport of canyoning occurs predominantly in the protected areas of the Greater Blue Mountains World Heritage Area, 50 km west of Sydney. It involves travelling through narrow, deep gorges using a combination of walking, abseiling, wading, rock scrambling and/ or swimming through the canyon streams. The sport’s popularity is reported to have increased substantially over time, causing concern for the sustainability of these fragile ecosystems. To investiga...

  9. Hoplatessara luxuriosa (Silvestri, 1895 (Diplopoda, Polydesmida, Paradoxosomatidae is native to Australia, not New Guinea

    Directory of Open Access Journals (Sweden)

    Robert Mesibov


    Full Text Available Hoplatessara luxuriosa (Silvestri, 1895 is partly redescribed and illustrated. Its native range is shown to be in the cool-climate uplands of New South Wales, Australia. H. luxuriosa was originally labelled as collected by L.M. D’Albertis at Sorong in New Guinea. D’Albertis collected on Sorong Island in 1872 and spent the following year in Sydney, New South Wales, before returning to Europe with his New Guinea specimens. It is possible that D’Albertis himself collected H. luxuriosa in 1873, and that the mislabelling occurred later.

  10. Water ecosystem services in northern Australia--how much are they worth and who should pay for their provision?

    Directory of Open Access Journals (Sweden)

    Kerstin K Zander

    Full Text Available There is ongoing pressure to develop the largely unaltered Daly River catchment in northern Australia for agriculture. However, a choice experiment among people in the region and in Australia's largest city, Sydney, shows that people are prepared to pay substantial amounts to maintain the quality of its ecosystem services. The total stated willingness-to-pay (WTP for a Daly River conservation programme was about $300, of which people would be willing to pay over half ($161 if the programme retained waterholes for Aboriginal people in good condition. The WTP for high quality recreational fishing and biodiversity values was $120 and $91 respectively. Using the average cost of a recreational fishing license in Australia ($35 as a basis for grounding the stated preferences in empirical values, as well as the cost of park entry fees and the amount of support society provides to agriculture in Australia, the total amount that the 110,000 people in the region are likely to be willing to pay for the retention of the values in the Daly River catchment is about $6 million, while the 4.5 million people in Sydney would be willing to pay about $81 million. A significant finding in this research is that, while fishing, biodiversity and agricultural values all have equivalents in the market economy, the value for which people were willing to pay most, the cultural value, has no equivalent at all and is thus receives almost no investment.

  11. Exploring infant feeding practices: cross-sectional surveys of South Western Sydney, Singapore, and Ho Chi Minh City. (United States)

    Leow, Timothy Yong Qun; Ung, Andrew; Qian, Shelley; Nguyen, Jessie Thanh; An, Yvonne; Mudgil, Poonam; Whitehall, John


    Infant feeding practices are known to influence the child's long-term health. Studies have associated obesity and other diseases with reduced breastfeeding and early introduction of high calorie beverages (HCBs). The rising prevalence of obesity is already a problem in most developed countries, especially Australia, but cultural differences are influential. Our aim is to examine and compare infant feeding practices and educational levels of respondents through questionnaires in three culturally different sites: Campbelltown (South Western Sydney), Australia, Singapore and Ho Chi Minh City, Vietnam (HCMC). Consenting parents and carers (aged ≥18 years old) of at least one child (≤6 years old) were recruited from paediatric clinics in Campbelltown, Singapore and HCMC. Participants completed an infant feeding practices questionnaire regarding breastfeeding, beverage and solid initiation in addition to the parent's ethnicity, age, and educational level. Data was analysed quantitatively using SPSS. Two hundred eighty-three participants were recruited across the three sites, HCMC (n = 84), Campbelltown (n = 108), and Singapore (n = 91). 237 (82.6%) children were breastfed but in all only 100 (60.2%) were exclusively breastfed for five months or more. There was a statistical difference in rates of breast feeding between each region. HCMC (n = 18, 21.4%) had the lowest, followed by Campbelltown (n = 35, 32.4%), and then Singapore (n = 47, 51.7%). There was also a difference in rates of introduction of HCBs by 3 years of age, with those in HCMC (n = 71, 84.5%) were higher than Campbelltown (n = 71, 65.8%) and Singapore (n = 48, 52.8%). The educational level of respondents was lower in Vietnam where only 46.4% (n = 39) had completed post-secondary education, compared to 75.0% (n = 81) in Campbelltown and 75.8% (n = 69) in Singapore. Rates of breast feeding were inversely correlated with rates of introduction of HCB and positively related to

  13. The decay of wood in landfills in contrasting climates in Australia

    Ximenes, Fabiano, E-mail: [Forest Science, Agriculture NSW, New South Wales Department of Primary Industries, Level 12, 10 Valentine Ave, Parramatta, NSW 2150 (Australia); Björdal, Charlotte [Department of Conservation, Gothenburg University, Guldhedsgatan 5A, Box 130, SE-405 30 Göteborg (Sweden); Cowie, Annette [NSW Department of Primary Industries, Beef Industry Centre, Trevenna Rd., University of New England, Armidale, NSW 2351 (Australia); Barlaz, Morton [Dept. of Civil, Construction, & Environmental Eng., North Carolina State University, Box 7908, Raleigh, NC 27695-7908 (United States)


    Highlights: • We examine decay in wood from landfills in contrasting environments in Australia. • Analysis is based on changes in chemical composition and microscopy. • Climate did not influence levels of decay observed. • Microscopy of retrieved samples revealed most of the decay was aerobic in nature. • Current default factors for wood decay in landfills overestimate methane emissions. - Abstract: Wood products in landfill are commonly assumed to decay within several decades, returning the carbon contained therein to the atmosphere, with about half the carbon released as methane. However, the rate and extent of decay is not well known, as very few studies have examined the decay of wood products in landfills. This study reports on the findings from landfill excavations conducted in the Australian cities of Sydney and Cairns located in temperate and tropical environments, respectively. The objective of this study was to determine whether burial of the wood in warmer, more tropical conditions in Cairns would result in greater levels of decay than occurs in the temperate environment of Sydney. Wood samples recovered after 16–44 years in landfill were examined through physical, chemical and microscopic analyses, and compared with control samples to determine the carbon loss. There was typically little or no decay in the wood samples analysed from the landfill in Sydney. Although there was significant decay in rainforest wood species excavated from Cairns, decay levels for wood types that were common to both Cairns and Sydney landfills were similar. The current Intergovernmental Panel on Climate Change (IPCC, 2006) default decay factor for organic materials in landfills is 50%. In contrast, the carbon loss determined for Pinus radiata recovered from Sydney and Cairns landfills was 7.9% and 4.4%, respectively, and 0% for Agathis sp. This suggests that climate did not influence decay, and that the more extensive levels of decay observed for some wood samples

  16. Structural Change in the Demand for Differentiated Meat Products in Sydney


    Gorny, Rachel A.; Ahmadi-Esfahani, Fredoun Z.


    Concerns about the recent trends away from the consumption of red meat have led to tests for structural change in demand. These tests have typically treated the individual meats as homogeneous commodities. This article uses disaggregated data to test for structural change in the demand for differentiated meat products in Sydney over the seasons from winter 1987 to autumn 1991 using a revealed preference approach. The results fail to provide any evidence of structural change.

  17. Acute myocardial injury caused by Sydney funnel-web spider (Atrax robustus) envenoming. (United States)

    Isbister, G K; Warner, G


    A 67-year-old female suffered envenoming by a Sydney funnel-web spider (Atrax robustus), complicated by ST elevation and elevated troponin levels consistent with an acute myocardial injury. She was treated primarily with funnel-web spider antivenom, admission to intensive care and initial respiratory support for acute pulmonary oedema. The mechanism by which funnel-web spider envenomation caused myocardial injury is unclear but follow-up nuclear studies in the patient demonstrated that she had minimal atherosclerotic disease.

  18. Medical e-commerce for regional Australia. (United States)

    Kumar, D K; Mikelaitis, P


    The residents of rural and regional Australia have less access to health care services than in capital cities. There is a reluctance of General Practitioners to practice in the country. New information technology and government initiatives are now addressing this problem. High bandwidth videoconferencing is now being routinely used to provide psychiatric consultations to areas without this service. But this (like many other implementations of telecommunication technologies to health) has resulted in loss of revenue to regional Australia while benefiting capital cities. Thus, the current implementation of telecommunication technology to health has resulted in loss of revenue of the regions while increasing the bias towards the cities. Further, the system is not economically viable and requires the Government to inject funds for the smooth operation of the system. This paper proposes the use of telecommunication technology for enabling the communities of regional Australia to access health facilities via physical and virtual clinics. The proposed technique is self supporting and is based in the country with the intent to prevent the drain of resources from regional Australia. The technique attempts to eradicate the problem at the root level by providing a business opportunity that is based in and to cater for the needs of the remote communities. The proposed system would provide health services by physical and virtual clinics and while serving the communities would be profit centres- and thus attracting doctors and other resources to the remote communities.

  19. Mahjong gambling in the Chinese-Australian community in Sydney: a prevalence study. (United States)

    Zheng, Wu Yi; Walker, Michael; Blaszczynski, Alex


    Mahjong is a popular gambling game played in Chinese communities all over the world (Papineau, China Perspect 28:29-42, 2000) and is sometimes referred to as '' (guodu, the Chinese national gambling game) or '' (xiu changcheng, repairing the Great Wall). Exploratory studies using snowball sampling conducted by Zheng et al. (J Psychol Chin Soc 9(2):241-262, 2008) indicated that Mahjong is not only a popular pastime within the Sydney Chinese community but also problematic for around 3% of players. The current study aimed to extend earlier studies by estimating the prevalence of Mahjong problem gambling in a random sample of Sydney Chinese community members. In addition, due to first-hand gambling experience of the first author with superstitious Mahjong players, the study also investigated the role of superstitious beliefs in Mahjong gambling. The current study involved a series of self-report questionnaires administered to 469 randomly selected Chinese Australians in Sydney. The problem gambling rate, assessed by the Canadian Problem Gambling Index (CPGI), was 3.8%, with Chinese males and older Chinese prominent. Superstitious beliefs were found to play a part in the maintenance of Mahjong gambling behaviour. Information stemming from the current study has helped gain insight into culturally specific forms of gambling, and to identify correlates of problem gamblers. Funding bodies and counselling services should be aware of the existence of this form of gambling, and should devise appropriate treatment plans for Mahjong problem gamblers.

  20. Twentieth century toxinology and antivenom development in Australia. (United States)

    Winkel, Kenneth D; Mirtschin, Peter; Pearn, John


    It was not until the last decade of the 19th century that an experimental approach (led by Bancroft in Queensland and Martin in Sydney and Melbourne) brought a higher plane of scientific objectivity to usher in the modern era of Australian toxinology. This Australia era, 1895-1905, coincided with and in some respects was the result of the new knowledge emerging from Europe and the Americas of the therapeutic effects of antitoxins. The subsequent systematic study of Australian venoms and toxins through to the 1930s and beyond, by Tidswell, Fairley, Ross, Kellaway and Cleland, set the foundation for Australia's leading reputation in venom research. As elsewhere, this development was to revolutionise the medical management of those victims who in the past had died in Australia from our venomous and toxic fauna. Morgan, Graydon, Weiner, Lane and Baxter at the Commonwealth Serum Laboratories emphasised the importance of cooperation between those expert at catching and milking the venomous creatures and those developing the antivenoms. Commercial antivenom manufacture began in Australia in 1930 with the tiger snake antivenom. This was followed by other antivenoms for the other important species (1955: taipan; 1956: brown snake; 1958: death adder; 1959: Papuan black snake; 1961: sea snake; 1962: polyvalent) including the first marine antivenoms in the world (1956: stonefish antivenom; 1970: box jellyfish) culminating, in 1980, with the release of the funnel web spider antivenom. More recent activity has focused on veterinary antivenoms and production of new generation human antivenoms for export (CroFab and ViperaTAB). This paper reviews some of the milestones of Australian toxinology, and antivenom development in particular, during the 20th century.

  1. Water Sources of Temperate Upland Swamps of Eastern Australia. Implications for Groundwater Management and Climate Change. (United States)

    Cowley, K.; Fryirs, K.; Chisari, R.; Hose, G. C.


    Temperate upland swamps in Eastern Australia are endangered ecological communities under State and National legislation. They occur in headwaters of low order streams on low relief plateaus, providing base flow to streams that contribute to Sydney's major drinking water supplies that support some 4.5 million people. The swamps are also subject to aquifer interference activities from long wall mining and groundwater extraction, and are threatened by a changing climate. It is therefore critical that we understand their water source, storage capacity and residence times. We collected seasonal water samples from perched swamp aquifers in two highland regions of Eastern Australia for analysis of hydrogen and oxygen isotopes and compared them with rainwater, surface water and deeper groundwater to determine whether the swamps were primarily rainwater or groundwater fed. 222Rn was used as an environmental tracer to calculate residence times and relative groundwater/surface water ratios. We found over 60% of the swamps were sensitive to evaporation which has implications for swamp health in a warmer climate. Over a third of water from the perched swamp aquifer is derived from deeper sandstone aquifers with residence times of between 1.2 and 15 days. This swamp-groundwater connectivity means that mining activities or large-scale groundwater extraction could interfere with a significant component of the swamps' water source, its water storage capacity and downstream contributions to Sydney's drinking water supplies.

  2. Japan-Australia Co-operative Program on research and development of technology for the management of high level radioactive wastes: phase II (1990-1995)

    The major activities associated with Japan-Australia Co-operative Program were the preparation, characterization and subsequent testing of both Cm-doped Synroc containing PW-4b simulated waste and Cm-doped single-phase zirconolite and perovskite, and the initiation of studies on naturally-occurring zirconolites to study the long-term durability of this mineral phase over geological time. The preparation of the Cm-doped samples was carried out in JAERI`s WASTEF facility at Tokai, with technical information and assistance provided by ANSTO where necessary. The experiments were designed to induce accelerated radiation damage in Synroc samples that would correspond to periods of Synroc storage of up to 100,000 years. The results are of considerable importance in evaluating the potential of the Synroc process as a means of dealing with HLW waste streams and represent a significant contribution to the understanding of the ability of Synroc to immobilize HLW elements. Overall the Phase II Co-operative Program has continued the excellent co-operative working relationship between the staff at the two institutions, and provided a better understanding of the potential advantages and limitations of Synroc as a second generation waste form. The work has shown the need for additional studies to be carried out on the effect of the levels of Cm-doping on the Cm leach rate, extension of natural analogue studies to define the geological conditions under which zirconolite is stable and development of models to provide long-term predictions of releases of HLW elements from Synroc under a range of repository conditions. It is strongly recommended that the program carried out in Phase II of the Co-operative Agreement be extended for a further three years to allow additional information on the above areas to be collected and reported in a document providing an overview of the Co-operative Program and recommendations on HLW management strategies.

    Drawing from a larger study that identified the supports and services that facilitate wellness among older people from rural communities, this study examined the specific contribution made by information and communication technology (ICT). Qualitative interviews were undertaken with 60 older adults from six Australian rural areas. A preliminary thematic analysis was conducted, followed by a higher-order inductive analysis. Information and communication technology use was discussed in terms of individual enrichment, and in terms of enabling connections between the individual and their social networks, community and wider service environments. Information and communication technologies may facilitate wellness for rural older people by compensating for geographical and social isolation. In the changing world of health and aged care service delivery, ICTs will be more important than ever for rural older people in building their capacity to access the services, socialisation and support that they need, regardless of location. © 2017 AJA Inc.

  4. Innovation Practice Using Pervasive Mobile Technology Solutions to Improve Population Health Management: A Pilot Study of Gestational Diabetes Patient Care in Australia. (United States)

    Wickramasinghe, Nilmini; Gururajan, Raj


    Healthcare service delivery is moving forward from individual care to population health management, because of the fast growth of health records. However, to improve population health performance, it is necessary to leverage relevant data and information using new technology solutions, such as pervasive diabetes mobile technology solution of Inet International Inc., which offers the potential to facilitate patient empowerment with gestational diabetic care. Hence, this article examines the pilot study outcomes of a small clinical trial focusing on pregnant patients affected by gestational diabetes mellitus, in an Australian not for profit healthcare context. The aims include establishing proof of concept and also assessing the usability, acceptability, and functionality of this mobile solution and thereby generate hypotheses to be tested in a large-scale confirmatory clinical trial.

  5. Geothermal structure of Australia's east coast basins (United States)

    Danis, C. R.; O'Neill, C.


    The east coast sedimentary basins of Australia formed on an active margin of eastern Gondwana, and constitute an important hydrocarbon resource. The 1600km long Sydney-Gunnedah-Bowen Basin (SGBB) is largest east coast basin system, with thick Permian to Jurassic sedimentary successions overlying Palaeozoic basement rocks. The SGBB has been the focus of renewed geothermal exploration interest, however, the thermal state and geothermal potential of the system is largely unconstrained. Geothermal exploration programs require an accurate estimate of subsurface temperature information, in addition to favourable geology, to make informed decisions on potential targe developments. Primarily temperature information comes from downhole measurements, generally non-equilibrated, which are traditionally extrapolated to depth, however such extrapolation does not take into account variations in geological structure or thermal conductivity. Here we import deep 3D geological models into finite element conduction simulations, using the code Underworld, to calculate the deep thermal structure of the basin system. Underworld allows us to incorporate complex, detailed geological architecture models, incorporating different material properties for different layers, with variable temperature and depth-dependent properties. We adopt a fixed top boundary temperature on a variable topographic surface, and vary the bottom surface boundary condition, to converge of models which satisfy equilibrated downhole temperature measurement constraints. We find coal plays an important role in insulating sedimentary basins. Heat refracts around the coal interval and produces elevated temperatures beneath thick sediments, especially where thick coal intervals are present. This workflow has been formalized into an Underworld geothermal model library, enabling model centric computational workflows. Using the imported model architecture from the geology, data can be continuously updated and added to the

  6. Patterns of Occurrence of Sharks in Sydney Harbour, a Large Urbanised Estuary. (United States)

    Smoothey, Amy F; Gray, Charles A; Kennelly, Steve J; Masens, Oliver J; Peddemors, Victor M; Robinson, Wayne A


    Information about spatial and temporal variability in the distribution and abundance of shark-populations are required for their conservation, management and to update measures designed to mitigate human-shark interactions. However, because some species of sharks are mobile, migratory and occur in relatively small numbers, estimating their patterns of distribution and abundance can be very difficult. In this study, we used a hierarchical sampling design to examine differences in the composition of species, size- and sex-structures of sharks sampled with bottom-set longlines in three different areas with increasing distance from the entrance of Sydney Harbour, a large urbanised estuary. During two years of sampling, we obtained data for four species of sharks (Port Jackson, Heterodontus portusjacksoni; wobbegong, Orectolobus maculatus; dusky whaler, Carcharhinus obscurus and bull shark, Carcharhinus leucas). Only a few O. maculatus and C. obscurus were caught, all in the area closest to the entrance of the Harbour. O. maculatus were caught in all seasons, except summer, while C. obscurus was only caught in summer. Heterodontus portusjacksoni were the most abundant species, caught in the entrance location mostly between July to November, when water temperature was below 21.5°C. This pattern was consistent across both years. C. leucas, the second most abundant species, were captured in all areas of Sydney Harbour but only in summer and autumn when water temperatures were above 23°C. This study quantified, for this first time, how different species utilise different areas of Sydney Harbour, at different times of the year. This information has implications for the management of human-shark interactions, by enabling creation of education programs to modify human behaviour in times of increased risk of potentially dangerous sharks.

  8. Patterns of the non-indigenous isopod Cirolana harfordi in Sydney Harbour.

    Ana B Bugnot

    Full Text Available Biological introductions can alter the ecology of local assemblages and are an important driver of global environmental change. The first step towards understanding the impact of a non-indigenous species is to study its distribution and associations in the invaded area. In Sydney Harbour, the non-indigenous isopod Cirolana harfordi has been reported in densities up to 0.5 individuals per cm(2 in mussel-beds. Abundances of this species have, however, been largely overlooked in other key habitats. The first aim of this study was to evaluate the abundances and distribution of C. harfordi across different habitats representative of Sydney Harbour. Results showed that C. harfordi occurred in oyster and mussel-beds, being particularly abundant in oyster-beds. We also aimed to determine the role of C. harfordi as a predator, scavenger and detritus feeder by investigating the relationships between densities of C. harfordi and (i the structure of the resident assemblages, and (ii deposited organic matter in oyster-beds. Densities of C. harfordi were not related to the structure of the assemblages, nor amounts of deposited organic matter. These findings suggested little or no ecological impacts of C. harfordi in oyster-beds. These relationships may, however, affect other variables such as growth of individuals, or be disguised by high variability of assemblages among different locations. Future studies should, therefore, test the impacts of C. harfordi on the size of organisms in the assemblage and use manipulative experiments to control for spatial variation. This study is the first published work on the ecology of the invasion of C. harfordi and provides the starting-point for the study of the impacts of this species in Sydney Harbour.

  9. Australia's polio risk. (United States)

    Martin, Nicolee; Paterson, Beverley J; Durrheim, David N


    Australia, like all polio-free countries and regions, remains at risk of a wild poliovirus importation until polio is eradicated globally. The most probable route of importation will be through a traveller arriving in Australia either by air or sea from a polio-endemic or re-infected country. While the overall risk of an imported wild poliovirus infection leading to transmission within Australia is assessed as being low, some areas of the country have been identified as at increased risk. Local areas with relatively high arrivals from polio endemic countries, areas of low vaccination coverage and the potential for transmission to occur when these 2 factors are combined, were identified by this review as Australia's main polio risk. The risk of an importation event leading to locally acquired cases is mitigated by generally high polio vaccination coverage in Australia. This high coverage extends to residents of the Torres Strait Islands who are in close proximity to Papua New Guinea, a country identified as at high risk of poliovirus transmission should an importation occur. In 2012, all states and territories had vaccination coverage of greater than 90% at 1 year of age and all exceeded 93% at 2 years of age. Population immunity to wild poliovirus type 1, which remains the major cause of paralysis globally, has been estimated at 82%. This is sufficient to prevent outbreaks of this type in Australia. Of the 211 eligible non-polio acute flaccid paralysis (AFP) cases classified between 2008 and 2011, 91% (193) were vaccinated against polio at least once. High quality surveillance for AFP, which is supplemented by sentinel enterovirus and environmental surveillance activities, gives confidence that an imported case would be detected and appropriate public health action would ensue.

  10. Healthcare in Australia. (United States)

    Dalton-Brown, Sally


    No single issue has dominated health practitioners' ethical debates in 2014 in Australia, but a controversial decision on gene patenting and the media focus on "Dr. Death," euthanasia campaigner Dr. Philip Nitschke, have given new life to these two familiar (and global) debates. Currently a dying with dignity bill, drafted by the Australian Green Party, is under examination. The Senate inquiry into the bill received more than 663 submissions, with 57% opposed and 43% in support of the bill, which has now been referred to a Senate committee. Will this be another of Australia's failed attempts to legalize euthanasia? The trial of Dr. Nitschke begins on November 10, 2014.

  11. Why Study in Australia?

    Institute of Scientific and Technical Information of China (English)



    Going overseas to pursue further studies is even more generalized in recent years. Students are open to a variety of op-tions to decide which country to go and which university to choose. Why wouldn’t you want to study with some of the best minds in the world? Australia is a leading global education power, with world’s best educators and facilities. It also provides both local and international students with a variety of quality study options. This essay presents some of the important reasons why in-ternational students should study in Australia in regard to education quality, affordable fees, government support, multiple cultures and immigration policies.

    Hart, K.; Vance, E.; Lumpkin, G. [Australian Nuclear Science and Technology Organisation, Lucas Heights, NSW (Australia); Mitamura, H.; Banba, T. [Japan Atomic Energy Research Inst. Tokai, Ibaraki (Japan)


    The overall aim of the Co-operative Program has been to promote the exchange of information on technology for the management of High-Level Wastes (HLW) and to encourage research and development relevant to such technology. During the 13 years that the Program has been carried out, HLW management strategies have matured and developed internationally, and Japan has commenced construction of a domestic reprocessing and vitrification facility for HLW. The HLW management strategy preferred is a national decision. Many countries are using vitrification, direct disposal of spent fuel or a combination of both to handle their existing wastes whereas others have deferred the decision. The work carried out in the Co-operative Program provides strong scientific evidence that the durability of ceramic waste forms is not significantly affected by radiation damage and that high loadings of actinide elements can be incorporated into specially designed ceramic waste forms. Moreover, natural minerals have been shown to remain as closed systems for U and Th for up to 2.5 b y. All of these results give confidence in the ability of second generation waste forms, such as Synroc, to handle future waste arisings that may not be suitable for vitrification 87 refs., 15 tabs., 22 figs.

  15. Modelling the Spatial-temporal Variation of Urban/peri-urban Forests and Their Ecosystem Services: a Case Study of North-West Sydney (United States)

    Odeh, I. A.; Zou, X. L.


    In terms of total terrestrial sequestered carbon, the global soils and forests are recognized as the predominant C sinks. Even though urban forests stored a relatively small proportion of the total terrestrial C, they also provide other important ecosystem services such as improving air quality, cooling effect in buildings and aesthetics. Thus in view of these environmental services the quantification of urban tree is increasingly viewed as essential to the understanding of how these ecosystem services can be optimized. The aims of this paper are to: i) quantify the spatial-temporal distribution of urban forests in Northwest Sydney using remote sensing techniques; ii) determine the total urban C-storage over many decades; iii) apply UFORE model to estimate air pollutant removal ability of urban forest. The results revealed the estimated total trees in Northwest Sydney in 2011was approximately 2.3 million. These urban forests potentially store an estimated 1.3 million tons of carbon in various forms such as biomass, soil carbon, etc. The relative carbon sequestration rate of these trees was estimated to be about 20,500 tC/yr (equivalent to AUD 467,000/year). Furthermore, the results show that trees near buildings can potentially avoid AUD 12.9 million of energy cost every year and 70000 tons of carbon emission, the latter which is equivalent to additional savings of nearly AUD 1.6 million per year. We also estimated that urban forests in the study area could potentially remove about 44,600 tons of pollutants (mainly greenhouse gases) annually equivalent to a saving of about AUD 409 million per year. Thus the results reveal the spatial-temporal variation of urban vegetation in the last twenty year between 1991 and 2011. The study has showcased the importance and potential role of urban forests in preserving carbon and thus reducing GHG emissions into atmosphere. Furthermore, these results highlight the significant value of urban forests in term of pollutant removal

  17. Immigrant Teachers in Australia

    Directory of Open Access Journals (Sweden)

    Jock Collins


    Full Text Available One of the features of contemporary society is the increasing global mobility of professionals. While the education industry is a key site of the demand for contemporary global professional migration, little attention has been given to the global circulation of education professionals. Over past decades, immigrant teachers have been an important component of skilled and professional immigration into Australia, there is no comprehensive contemporary national study of the experiences of immigrant teachers in Australia. This article aims to fill this gap and to answer questions about their decision to move to Australia, their experience with Australian Education Departments in getting appointed to a school, their experiences as teachers in the classroom and in their new Australian community. It draws on primary data sources - in the form of a survey of 269 immigrant teachers in schools in NSW, SA and WA conducted in 2008-9 - and secondary sources - in the form of the 2006 national census and Longitudinal Survey of Immigrants in Australia – to provide insights into immigrant teachers in Australian schools, adding also to our understanding of Australia’s contemporary immigration experience.

    Stein, W.; Imenes, A.; Hinkley, J.; Benito, R.; McEvoy, S.; Hart, G.; McGregor, J.; Chensee, M.; Wong, K.; Wong, J.; Bolling, R.


    The abundance of high quality solar radiation in Australia has long fuelled activity in solar energy, particularly CSP. The National Solar Energy Centre is being established in Australia as a centre to promote all facets of concentrating solar thermal technology, from fundamental R and D to active demonstrations and testing platforms. The Centre comprises a 550kW solar tower with very high heliostat packing density, linear concentrators that will drive both an organic Rankine cycle and solar chiller, and eventually a dish concentrator. Other papers in these conference proceedings discuss in detail particular aspects of design, fabrication and testing of components of the tower. This paper provides an overview of the intended activities of the Centre and particularly the opportunities for international collaboration, including high temperature receiver design and testing, medium temperature receivers, solarized Brayton cycles, thermochemical reactors and materials for solar hydrogen production, and improved small solar trough technology.

    Zheng, Qing-ming; Zeng, Hua-tang; Dai, Chuan-wen; Zhang, Shun-xiang; Zhang, Zhen; Mei, Shu-jiang; He, Ya-qing; Ma, Han-wu


    An outbreak of norovirus GII.4/Sydney_2012 affected a China elder care facility in December 2012. A total of 39 elderly people and staff met the outbreak case definition. The attack rates in the elderly and the staff were 15.9% (31/195) and 23.2% (19/82), respectively, including 13 asymptomatic cases in the staff. The result of gene sequencing revealed that the outbreak was caused by norovirus GII.4 Sydney. The mode of transmission of this outbreak was proven to be person-to-person. The first case (a self-cared elder) was affected outside the elder care facility and was not isolated after returning. Norovirus was transmitted via close contact among the self-cared elderly. Then, through service-related close contact, the attendants promoted the cross-transmission between the self-cared elderly and the nursed elderly. The virus was also spread among the staff via daily contact. In the elder care facility, the asymptomatic cases in the attendants played an important role in the transmission of norovirus, which deserves high attention.

  3. Socioeconomic differences in the cost, availability and quality of healthy food in Sydney. (United States)

    Crawford, Belinda; Byun, Roy; Mitchell, Emily; Thompson, Susan; Jalaludin, Bin; Torvaldsen, Siranda


    To compare the cost of a basket of staple foods, together with the availability and quality of fresh fruit and vegetables, by supermarket store type in high and low socioeconomic suburbs of Sydney. A food basket survey was undertaken in 100 supermarkets in the 20 highest and 20 lowest socioeconomic suburbs of Sydney. We assessed the cost of 46 foods, the range of 30 fresh fruit and vegetables and the quality of ten fresh fruit and vegetables. Two major supermarket retailers, a discount supermarket chain and independent grocery stores were surveyed. The food basket was significantly cheaper in low compared to high socioeconomic suburbs ($177 vs $189, psupermarkets were at least 30% cheaper than other supermarket stores. There were fewer varieties and poorer quality fruit and vegetables in stores in low socioeconomic suburbs. Food basket prices and the availability and quality of fruit and vegetables varied significantly by store type and socioeconomic status of suburb. Implications for public health: A nationwide food and nutrition surveillance system is required to inform public health policy and practice initiatives. In addition to the food retail environment, these initiatives must address the underlying contributors to inequity and food insecurity for disadvantaged groups. © 2017 The Authors.

  4. Sustainable Development Strategy for the Global City: A Case Study of Sydney

    Directory of Open Access Journals (Sweden)

    Richard Hu


    Full Text Available Global cities, the command and control centres of the integrated world economy, are facing a sustainability paradox of greater global competition and greater environmental pressure. This study explores the policy approaches to the sustainability paradox by integrating environmental sustainability and economic competitiveness into the development strategy for “the global city”, based on a case study of Sydney. Dissecting Sustainable Sydney 2030, the strategy to guide the City’s development in the early 21st century, reveals the approaches used to achieve the integration. The approaches include green economy, sustainable redevelopment, integrated transport and connectivity, development of attractive public space, urban design for sustainable and good-looking urban form, marketisation of sustainability for a competitive edge, and a relational planning approach. Altogether they target mutually supportive benefits of environmental sustainability and economic competitiveness. The findings point out new directions for the City’s strategic development, and suggest a useful reference for counterpart global cities to address the common sustainability paradox.

  5. Lead, arsenic and polycyclic aromatic hydrocarbons in soil and house dust in Sydney Nova Scotia

    Energy Technology Data Exchange (ETDEWEB)

    Lambert, T.W. [Calgary Univ., AB (Canada); Lane, S. [York Univ., Toronto, ON (Canada). School of Environmental Studies


    This paper presents the results of a lead and arsenic soil and dust study conducted in Sydney, Nova Scotia in August 2002. Whitney Pier, Ashby and North End are 3 communities surrounding the Sydney tar ponds, steel and coke oven sites that have been significantly impacted by the industrial activity of the past century. Lead and arsenic was found in the floor dust of every home evaluated. The neighbourhoods were also found to be contaminated with polycyclic aromatic hydrocarbons (PAHs). There is a low but significant health risk from exposure to lead and arsenic in the soil and house dust, and all three communities must be remediated to prevent health impacts. This report by the Sierra Club criticizes an earlier report by the Joint Action Group (JAG), a tri-governmental process which never took into consideration the fact that people's yards and homes are contaminated and need to be remediated. This report criticizes that the JAG report neglected the issue of people's health and is calling on the federal Health Minister to take action on the environmental disaster. 17 refs., 8 tabs., 1 fig.

    There is strong and consistent evidence from large scale randomised controlled trials that type 2 diabetes can be prevented or delayed through lifestyle modification which improves diet quality, increases physical activity and achieves weight loss in people at risk. Worldwide, the prevalence of type 2 diabetes is increasing in individuals of Chinese descent. Culturally tailored programs are required to address the risk in the Chinese population. This paper analyses effectiveness of a culturally tailored community-based lifestyle modification program (Sydney Diabetes Prevention Program (SDPP)) targeting Mandarin speakers. The SDPP was a 12 month translational study aiming to promote increased physical activity and dietary changes. Effectiveness was assessed through the improvement of anthropometric, metabolic, physical activity and dietary outcomes and number of goals met. Seventy-eight Mandarin-speaking participants at a high risk (Australian Diabetes Risk, AUSDRISK≥15) of developing diabetes were recruited for this study. In this cohort, waist circumference, total cholesterol and fat intake significantly improved at the 12-month review. In comparison to the English-speaking stream, the Mandarin-speaking stream achieved fewer improvements in outcomes and goals. The SDPP was not effective in reducing the risk factors associated with developing type 2 diabetes in this cohort of high risk Mandarin-speaking individuals living in Sydney.

  7. Toxinology in Australia's colonial era: a chronology and perspective of human envenomation in 19th century Australia. (United States)

    Pearn, John; Winkel, Kenneth D


    The medical management of those envenomed by snakes, spiders and poisonous fish in Australia featured extensively in the writings 19th century doctors, expeditioners and anthropologists. Against the background of this introduced medical doctrine there already existed an extensive tradition of Aboriginal medical lore; techniques of heat treatment, suction, incision and the application of plant-derived pharmacological substances featured extensively in the management of envenomed victims. The application of a hair-string or grass-string ligature, suctioning of the bite-site and incision were practised in a variety of combinations. Such evolved independently of and pre-dated such practices, which were promoted extensively by immigrant European doctors in the late 19th century. Pacific scientific toxinology began in the 17th century with Don Diego de Prado y Tovar's 1606 account of ciguatera. By the end of the 19th century more than 30 papers and books had defined the natural history of Australian elapid poisoning. The medical management of snakebite in Australia was the focus of great controversy from 1860 to 1900. Dogmatic claims of the supposed antidote efficacy of intravenous ammonia by Professor G.B. Halford, and that of strychnine by Dr. Augustus Mueller, claimed mainstream medical attention. This era of potential iatrogenic disaster and dogma was brought to a conclusion by the objective experiments of Joseph Lauterer and Thomas Lane Bancroft in 1890 in Brisbane; and by those of C.J. Martin (from 1893) and Frank Tidswell (from 1898), both of Sydney. The modern era of Australian toxinology developed as a direct consequence of Calmette's discovery, in Paris in 1894, of immune serum, which was protective against snakebite. We review the key contributors and discoveries of toxinology in colonial Australia.

  8. Population options for Australia. (United States)

    Ruddock, P


    In an address to the Australian Population Association Biennial Conference during October 1998, the Immigration and Multicultural Affairs Minister Philip Ruddock argued that neither the zero net overseas migration policy nor the massive boost in immigration are in the national interest of Australia. Environmental groups generally view that Australia should adopt a policy of zero net overseas migration. On the other hand, business and industry bodies consider that a substantial increase in the migration intake is needed in order to increase economic growth and to reduce the impact of an aging population. Moreover, some are concerned about population targets reaching up to 50 million in 50 years time. Thus, management of immigration policy is a difficult balancing act between competing objectives. The Minister concluded that their immigration program must operate on a totally global and nondiscriminatory basis regarding matters such as race, religion, color, and ethnic origin.

  9. Pleistocene Paleoart of Australia

    Directory of Open Access Journals (Sweden)

    Robert G. Bednarik


    Full Text Available Pleistocene rock art is abundant in Australia, but has so far received only limited attention. Instead there has been a trend, begun over a century ago, to search for presumed depictions of extinct megafauna and the tracks of such species. All these notions have been discredited, however, and the current evidence suggests that figurative depiction was introduced only during the Holocene, never reaching Tasmania. Nevertheless, some Australian rock art has been attributed to the Pleistocene by direct dating methods, and its nature implies that a significant portion of the surviving corpus of rock art may also be of such age. In particular much of Australian cave art is of the Ice Age, or appears to be so, and any heavily weathered or patinated petroglyphs on particularly hard rocks are good candidates for Pleistocene antiquity. On the other hand, there is very limited evidence of mobiliary paleoart of such age in Australia.

  10. Year book Australia 1986

    Energy Technology Data Exchange (ETDEWEB)

    Castles, I. (comp.)


    The Year Book is the principal reference work produced by the Central Office of the Australian Bureau of Statistics (ABS). It provides a comprehensive and detailed statistical review of all asepcts of the economy and social conditions of Australia. In addition, it contains descriptive matter dealing with Australia's history, geography, physiography, climate and meteorology, government, defence, international relations, culture and environment. The first Official Year Book was published early in 1908. This is the seventieth Year Book issued under the authority of the Commonwealth Government and follows a similar pattern to previous editions. However chapters have been revised and new material has been added. Most of the statistics contained in this volume relate to the years ended June or December 1984 to 1985. More detailed, and in most cases more recent, statistics are available in other ABS publications.

  11. Tissue banking in australia. (United States)

    Ireland, Lynette; McKelvie, Helen


    The legal structure for the regulation of tissue banking has existed for many years. In Australia, the donation of human tissue is regulated by legislation in each of the eight States and Territories. These substantially uniform Acts were passed in the late 1970's and early 1980's, based on model legislation and underpinned by the concept of consensual giving. However, it was not until the early 1990's that tissue banking came under the notice of regulatory authorities. Since then the Australian Government has moved quickly to oversee the tissue banking sector in Australia. Banked human tissue has been deemed to be a therapeutic good under the Therapeutic Goods Act 1989, and tissue banks are required to be licensed by the Therapeutic Goods Administration and are audited for compliance with the Code of Good Manufacturing Practice- Human Blood and Tissues. In addition, tissue banks must comply with a myriad of other standards, guidelines and recommendations.

  12. American Outlaws in Australia



    An aspect of the diffusion of American popular culture is examined in this research drawing upon national survey data. Measuring Australians¡¯ knowledge of American and Australian outlaws, we found that Jesse James and Billy the Kid are better known in Australia than any of the local outlaws, or bushrangers, with the exception of Ned Kelly. While a relatively large proportion of Australians identified Ned Kelly, Ben Hall, Jesse James and Billy the Kid as outlaws, few identified other Australi...

  13. Melville Island, Australia (United States)


    Melville Island, just off the coast of Darwin, Northern Territory, Australia (11.5S, 131.0E) is a sparsely inhabited tropical island with heavy woodland concentrations. The widespread and prominant smoke plumes were most likely set to renew pasture under open canopy woodland. Soil erosion is almost non- existant as can be seen by the clear and clean river flow. The offshore sediments are coastal current borne deposits from King Sound to the west.

  14. The regolith in Australia (United States)

    Ollier, C. D.


    Australian regolith materials are described, many of which are complex. Much Australian regolith dates back to the Tertiary, Mesozoic or earlier. There is a progressive change in the nature of alluvium through the Tertiary. Aridity, revealed through sand dunes and evaporites, is confined to the Quaternary. Ferricretes and silcretes are formed on lower slopes, often followed by inversion of relief. Tectonic isolation of Australia as well as climatic change is responsible for the change in the nature of terrestrial sediments since the Cretaceous.

  15. Social and Cultural Factors Affecting Complementary and Alternative Medicine (CAM Use during Menopause in Sydney and Bologna

    Directory of Open Access Journals (Sweden)

    Corinne van der Sluijs


    Full Text Available Background. Previous surveys found CAM use during menopause to be popular. This paper compares the results from two surveys (Sydney and Bologna to examine factors that determine the extent and pattern of CAM use to alleviate menopausal symptoms. Methods. Women, aged 45–65 years, who were symptomatic when transitioning through menopause or asymptomatic but taking menopause-specific treatments, were recruited in Sydney (n=1,296 and Bologna (n=1,106 to complete the same voluntary, anonymous, and self-administered questionnaire. The results were reanalysed using stratified analyses to determine similarities and differences. Results. Demographics of the two cohorts differed significantly. CAM was more popular in Sydney. The most significant determinants of CAM use were the use of CAM for other conditions besides menopause and the severity of vasomotor symptoms. Occupational status was a determinant of CAM use amongst Bologna respondents only. In order to relieve symptoms, Australian and Italian women used different CAM modalities whose effectiveness was generally perceived as good. Conclusion. CAM use is popular amongst menopausal women from Sydney and Bologna. Differences in the patterns of CAM use seem to depend on CAM availability and on the educational level and professional status of users. The complex interaction between market, social, and cultural factors of CAM use seems to be more influential on women’s choice of CAM than the available evidence of their effectiveness.

  20. Hired Hands: Casualised Technology and Labour in the Teaching of Cultural Studies

    Directory of Open Access Journals (Sweden)

    Kieryn McKay


    Full Text Available This article examines the uptake and application of podcasting in a particular higher education context, drawing on the the authors' experience in late 2008 when both were employed as casual tutors on large-scale first-year communications and cultural studies courses at the University of Western Sydney. The article maps out the limits of technological innovation within the teaching of cultural studies, as well as its limits in promoting the radical potential of a cultural studies approach. It also charts some of the effects and affects of an over-reliance on casualised labour, which we argue can have a profoundly destabilising and atomising impact on academic practice and student engagement. We argue there is a parallel between the appropriation of popular media technologies into the university and the current system of casual academic employment in Australia, in that both the podcast and the casual academic represent ‘new’ interfaces of outsourced academic labour. Stipulated from our positions as casual teachers in cultural studies, this article is written from an embedded perspective which conceptualises both the podcast and the casual academic in line with the most prevalent mode of their employment in the academy: as ‘hired hands’, appendages to traditional models of pedagogy.

  1. Assessment of sediment quality in Avicennia marina-dominated embayments of Sydney Estuary: the potential use of pneumatophores (aerial roots) as a bio-indicator of trace metal contamination. (United States)

    Nath, Bibhash; Birch, Gavin; Chaudhuri, Punarbasu


    Currently, coastal intertidal environments are under stress from increased contaminant loads due to urbanization and other anthropogenic disturbances. Mangrove habitats are abundant in tropical and sub-topical intertidal zones and frequently act as a metal bio-filter in estuarine systems. Mangrove reforestation is often considered as one of the management options to protect estuarine-marine habitats. The main objective of the present investigation was to assess the bio-indicator potential of Avicennia marina by determining heavy metal concentrations in pneumatophore (aerial root) tissues and ambient sediments from Sydney Estuary (Australia). We collected mangrove sediments and pneumatophores in fifteen locations covering five major embayments of the estuary for a detailed biogeochemical investigation. Metal concentrations in sediment were mostly above Australian interim sediment quality guidelines (ISQG)-Low and in few instances above ISQG-High values. Enrichment factors (EFs >6, especially of Cu, Pb and Zn) suggest "very severe" modification of sediment in Sydney Estuary in all but one embayment which was mainly due to rapid changes in land use in connection with urbanization. High bio-concentration factors (BCFs) were observed for Cu and Ni in comparison with other metals (i.e., As, Cd, Co, Cr, Pb and Zn). A strong, positive relationship between metals in sediments and pneumatophores suggests potential use of these tissues as a bio-indicator of estuarine contamination and that metals are entering the biotic environment. The study further highlights a positive role of mangroves in sequestering metals from sediments and the water column and thus protecting estuarine environments from pollution.

  2. Overcoming the pitfalls of abandoned mine workings in the Sydney coalfield

    Energy Technology Data Exchange (ETDEWEB)

    Forrester, D.; Noble, B. [AECOM, Sydney, NS (Canada)


    Previous coal mining activities in Sydney, Nova Scotia (NS) have included the creation of shallow, unrecorded underground coal extraction sites known as bootleg pits. The sites are a public safety hazard and can also impact groundwater flow. This paper presented an outline of the remediation strategies used to mitigate the hazards associated with the bootleg pits as part of a mine site closure and reclamation program currently being completed by the Cape Breton Corporation (ECBC). The strategies included the use of sinkhole subsidence hazard maps. Long-term visual monitoring is also being used in areas associated with sinkhole development. Larger abandoned areas have been cleared, backfilled and re-graded while including provisions for the ongoing drainage of mine waters. Gas monitoring and safety procedures were also reviewed. 2 refs., 4 figs.

  3. Low level exposures to lead and neurobehavioral development: the Sydney lead study

    Energy Technology Data Exchange (ETDEWEB)

    Cooney, G.H.; Bell, A.; McBride, W.; Carter, C.


    The Sydney lead study is a prospective five year study investigating the relationship between low level lead exposures and neurobehavioral development during the first five years of life. From an initial cohort of 318 children, 207 remained at the end of the fourth year. Average blood lead levels at 42 and 48 months were 10.6 ug/dL and 10.1 ug/dL respectively, with only a minority of the observations exceeding 15 ug/dL. The series of regression analyses reported in this paper support earlier findings from the study, that exposures to lead which give rise to the range of blood lead levels found in this cohort of children are not associated with cognitive or motor deficits in the preschool years.

  4. Palynological evidence for Pennsylvanian (Late Carboniferous) vegetation change in the Sydney Coalfield, eastern Canada

    Energy Technology Data Exchange (ETDEWEB)

    Dimitrova, T.K.; Zodrow, E.L.; Cleal, C.J.; Thomas, B.A. [Bulgarian Academy of Sciences, Sofia (Bulgaria). Inst. of Geology


    The palynology of elastic samples from seven stratigraphical levels in the late Moscovian Sydney Mines Formation, exposed along the shore at Bras d'Or, Nova Scotia, has been investigated. Most of the samples were from roof shales of major coals; the one sample that was not yielded a much higher proportion of pollen derived from extra-basinal vegetation. The four stratigraphically lower roof shale samples yielded essentially similar palynological spectra, with 39 {+-} 4% lycophytes, 9 {+-} 4% sphenophylls, 23 {+-} 4% tree-ferns, 12 4% other ferns and 5 {+-} 3% cordaites. The palynology of the upper part of the investigated succession suggests a shift in vegetation towards one favouring more marattialean tree-ferns, cordaites and conifers, and fewer lycophytes. This correlates with changes in drainage patterns as the alluvial plain migrated seawards and thus changed water tables. No evidence was found to suggest significant climate change at this time.

  5. Vanished Thresholds: Colonial Gentry and the Shaping of One of Sydney's Earliest Suburbs

    Directory of Open Access Journals (Sweden)

    Lesley Johnson


    Full Text Available This article explores the way a colonial gentry was constituting itself as a social grouping in the mid nineteenth century through shaping the landscape and material culture of suburbs such as Darling Point in Sydney. In doing so , they sought to create an 'infrastructure of certainty' for themselves in the challenging and volatile world of what was still predominantly a penal colony. Important to this investigation is an understanding of the lack of stability of this social grouping, particularly in its earliest years, and how this was played out in the subdivisions of land and the building, ownship and furnishing of the early stone villas of this area. I am interested in what this built environment might suggest about the effectivity of material culture in the mobilisation and performance of class, gendered and racial identities in particular urban environments in the nineteenth century.

    A new beam-combination and detection system has been installed in the Sydney University Stellar Interferometer working at the red end of the visual spectrum (wavelength range 500-950 nm) to complement the existing blue-sensitive system (wavelength range 430-520 nm) and to provide an increase in sensitivity. Dichroic beam-splitters have been introduced to allow simultaneous observations with both spectral system, albeit with some restriction on the spectral range of the longer wavelength system (wavelength range 550-760 nm). The blue system has been upgraded to allow remote selection of wavelength and spectral bandpass, and to enable simultaneous operation with the red system with the latter providing fringe-envelope tracking. The new system and upgrades are described and examples of commissioning tests presented. As an illustration of the improvement in performance the measurement of the angular diameter of the southern F supergiant delta CMa is described and compared with previous determinations.

    Sophia Barnes


    Full Text Available In 2012, staff in Student Support Services at The University of Sydney piloted an early intervention program to increase first year student engagement and retention. Founded in best-practice, evidence-based research, the Track and Connect program was developed in response to a study into first year undergraduate student attrition by the University’s Planning and Information Office, in consultation with Counselling and Psychological Services. Track and Connect provides tailored advice and support to students identified as at risk of withdrawal from a key first-year subject by demographic markers and on-time data. Trained senior peers contact these students and provide information, encouragement and service referrals at key decision points throughout the semester. This report outlines the program’s development, implementation and early outcomes, and identifies areas for refinement and expansion.

  8. Growth hormone and insulin-like growth factor I in a Sydney Olympic gold medallist. (United States)

    Armanini, D; Faggian, D; Scaroni, C; Plebani, M


    An Italian athlete who won a gold medal at the Sydney Olympic Games was studied. She was accused of doping after the finding of high levels of plasma growth hormone (GH) before the Games. She was studied firstly under stressed and then under unstressed conditions. In the first study, GH was measured every 20 minutes for one hour; it was above the normal range in all blood samples, whereas insulin-like growth factor I (IGF-I) was normal. In the second study, GH progressively returned to accepted normal levels; IGF-I was again normal. It was concluded that the normal range for GH in athletes must be reconsidered for doping purposes, because athletes are subject to stress and thus to wide variations in GH levels.

  9. Adverse reactions in a population of Sydney pet rabbits vaccinated against rabbit calicivirus. (United States)

    Tung, T; Phalen, D; Toribio, J-Alml


    To determine the general clinical presentation and incidence of adverse reactions to Cylap® RCD vaccinations, of a nature serious enough for veterinary attention, in a Sydney population of pet rabbits. A retrospective survey using hospital databases. Nine veterinary hospitals in Sydney participated in a database search for the number of rabbits vaccinated within a 2-year period. The hospitals involved had an identified interest in rabbit medicine and included general, specialist and teaching hospitals. Details of the rabbit, vaccination event and any possible reaction were collected and analysed. Of 933 events recorded in 705 rabbits, 17 (1.8%) adverse reactions were observed. Of the adverse events, local injection site reactions (alopecia, abrasions and scabbing) were most common. Other reactions, including systemic signs of gastrointestinal tract stasis, lethargy and forelimb lameness, were also documented. Overall, rabbits presented for vaccination were mostly male (57.7%) and desexed (71.3%), with an average age of 28.1 months (median 19.0, range 1.4-149.8 months) and an average weight at first vaccination of 2.12 kg (median 2.08 kg, range 0.18-5.6 kg). A significant association between increasing age and decreased incidence of adverse events was demonstrated (P value, 0.038). The benefits of vaccination against RCV outweigh the risks of an adverse reaction occurring. Data from this study show that adverse reactions occur infrequently, are generally mild and self-resolving, and decrease in incidence with increasing age. These results are similar to previous field research on wild rabbit colonies and reports from government and industry. © 2015 Australian Veterinary Association.

  10. Ethnicity and Public Space in the City: Ethnic Precincts in Sydney

    Directory of Open Access Journals (Sweden)

    Jock Collins


    Full Text Available Ethnic precincts are one example of the way that cultural diversity shapes public spaces in the postmodern metropolis. Ethnic precincts are essentially clusters of ethnic or immigrant entrepreneurs in areas that are designated as ethnic precincts by place marketers and government officials and display iconography related to that ethnicity in the build environment of the precinct. They are characterized by the presence of a substantial number of immigrant entrepreneurs of the same ethnicity as the precinct who line the streets of the precinct selling food, goods or services to many co-ethnics and non co-ethnics alike. Ethnic precincts are thus a key site of the production and consumption of the ethnic economy, a commodification of place where the symbolic economy of space (Zukin 1995:23-4 is constructed on representations of ethnicity and ‘immigrantness’. To explore some dimensions of the way that ethnic diversity shapes public space we present the findings of recent fieldwork in four Sydney ethnic precincts: Chinatown, Little Italy, Auburn (“Little Turkey” and Cabramatta (“Vietnamatta”. This fieldwork explores the complex and sometimes contradictory relationship between immigrant entrepreneurs, local government authorities, and ethnic community representatives in shaping the emergence of, and development of, ethnic precincts. It demonstrates how perceptions of the authenticity of precincts as ethnic places and spaces varies in the eyes of consumers or customers according to whether they are ‘co-ethnic’, ‘co-cultural’ or ‘Others”. It explores relations of production and consumption within the ethnic precinct and how these are embedded within the domain of regulation in the daily life of these four Sydney ethnic precincts.

  11. The relationship of current depressive symptoms and past depression with cognitive impairment and instrumental activities of daily living in an elderly population: the Sydney Memory and Ageing Study. (United States)

    Reppermund, S; Brodaty, H; Crawford, J D; Kochan, N A; Slavin, M J; Trollor, J N; Draper, B; Sachdev, P S


    Depressive symptoms are common in the elderly and they have been associated with cognitive and functional impairment. However, relatively less is known about the relationship of a lifetime history of depression to cognitive impairment and functional status. The aim of this cross-sectional study was to assess whether current depressive symptoms and past depression are associated with cognitive or functional impairment in a community-based sample representative of east Sydney, Australia. We also examined whether there was an interaction between current and past depression in their effects on cognitive performance. Eight hundred non-demented aged participants received a neuropsychological assessment, a past psychiatric history interview and the 15-item Geriatric Depression Scale. The Bayer-Activities of Daily Living scale was completed by an informant to determine functional ability. Clinically relevant depressive symptoms were present in 6.1% of the sample and 16.6% reported a history of depression. Participants with current depression had significantly higher levels of psychological distress and anxiety, and lower life satisfaction and performed worse on memory and executive function compared to participants without current depression. After controlling for anxiety the effect on executive function was no longer significant while the effect on memory remained significant. A history of depression was associated with worse executive function, higher levels of psychological distress and anxiety, and lower life satisfaction. After controlling for psychological distress the effect of past depression on executive function was no longer significant. There were no significant interactions between current and past depression in their effects on cognitive performance. There were no differences between participants with or without current depression and with or without past depression on functional abilities. These results support the view that current and past depressive

    Directory of Open Access Journals (Sweden)

    Editorial, Equipo


    Full Text Available A bridge is now being built at Gladesville, Australia, of reinforced and prestressed concrete, which having a span of 277 m, will be the largest of its type in the world. The main arch consists of four parallel ribs, each 277 m in span. These ribs are hollow, and constitute the main structure of the arch. There are four secondary access spans on each side. The initial project was somewhat altered by the Sydney Dept. of Public Works. Each of the four main ribs of the central arch leaves 36 m clear height for fluvial navigation. The arched ribs are made up of 108 hollow units, each weighing 50 tons. At suitable intervals a number of transversal, prestressed diaphragms have been fitted, which serve to mutually stabilise the ribs. On the ribs a palisade of vertical supports carry the bridge deck. This is 22 m wide and has two sidewalks, each 1.80 m wide. The prestressed deck girders were made at two nearby workshops, one on each side of the bridge. The construction of the ribs was completed with the aid of a metallic scaffolding, which was moved from one rib to the next and served for the erection of all of them. Prestressing was done with Freyssinet type plane jacks. These were placed between the rib units, which were compressed, at the same as forcing the arch to lift off the scaffolding. After the oil had compressed the concrete, it was substituted by cement mortar. The operation was repeated at various points for each rib.En Gladesville, Sydney (Australia, se construye un puente, de hormigón armado y pretensado, que, por sus 277 m de luz, será el mayor de los hasta hoy construidos en arco.

    Objective Despite public interest in the rural workforce, there are few published data on the geographical distribution of Australia's rural surgeons, their practice skill set, career stage or work-life balance (on-call burden). Similarly, there has not been a peer-reviewed skills audit of rural training opportunities for surgical trainees. The present study undertook this baseline assessment for Western Australia (WA), which has some of the most remote practice areas in Australia.Methods Hospital staff from all WA Country Health Service hospitals with surgical service (20 of 89 rural health services) were contacted by telephone. A total of 18 of 20 provided complete data. The study questionnaire explored hospital and practice locations of practicing rural surgeons, on-call rosters, career stage, practice skill set and the availability of surgical training positions. Data were tabulated in excel and geographic information system geocoded. Descriptive statistics were calculated in Excel.Results Of the seven health regions for rural Western Australia, two (28.6%) were served by resident surgeons at a ratio consistent with Royal Australasian College of Surgeons (RACS) guidelines. General surgery was offered in 16 (89%) hospitals. In total, 16 (89%) hospitals were served by fly-in, fly-out (FIFO) surgical services. Two hospitals with resident surgeons did not use FIFO services, but all hospitals without resident surgeons were served by FIFO surgical specialists. The majority of resident surgeons (62.5%) and FIFO surgeons (43.2%) were perceived to be mid-career by hospital staff members. Three hospitals (16.7%) offered all eight of the identified surgical skill sets, but 16 (89%) offered general surgery.Conclusions Relatively few resident rural surgeons are servicing large areas of WA, assisted by the widespread provision of FIFO surgical services. The present audit demonstrates strength in general surgical skills throughout regional WA, and augers well for the training

    Lilley, F. E. M.

    Electromagnetic induction at the terrestrial surface is a general and ubiquitous process. This note, which covers research on the subject in Australia, reflects the writer's own interest and refers particularly to induction by natural source fields in the period range of 1 minute to 1 day.Such source fields arise external to Earth, in the ionosphere and beyond, in the magnetosphere. The process of electromagnetic induction by these fields involves the flow through Earth of tens of thousands of amperes, over scale lengths of thousands of kilometers.

    The BP 7180 module produced by BP Solar was tested in Sydney, Australia, and Kassel, Germany in open fields in realistic operating conditions. Empirical adaptations were used for achieving optimal module performance in PTC conditions. The results were compared with flash test results and with rated capacities. The modules achieved efficiencies up to 86 percent, even with low radiation densities of 200 W/m{sup 2} and a remarkable good light yeald in weak light of less than 50 W/m{sup 2}. (orig.)

  17. Local government conservation and management of native vegetation in urban Australia. (United States)

    Stenhouse, Renae N


    Reflecting a worldwide trend of devolution of power and responsibilities to local authorities, metropolitan local governments in Australia now have a role in protecting and managing native vegetation (bushland). Reporting on questionnaire and interview results for Sydney, Melbourne, Perth, and Adelaide, this research examines the main disturbances in local government bushlands, local governments' efforts in bushland conservation, and universality of issues and responses among the cities and between urban and urban-rural local authorities. A number of disturbances in bushlands are common among the cities, with weeds, development impacts, and urban run off perceived to be the most threatening. Management efforts focus on weed control, whereas other main disturbances are receiving less attention. Community involvement in management is prevalent, although regional coordination among local governments is limited. Local governments are willing to be involved in biodiversity conservation and their capacity would be enhanced with increased funding, staffing, and regional coordination.

  18. HIV research in Australia: linking basic research findings with clinical and public health outcomes

    Directory of Open Access Journals (Sweden)

    Kaldor John M


    Full Text Available Abstract Despite a population of only 20 million and sustained low prevalence of HIV infection in Australia, Australian researchers have provided many substantial original findings to the fields of HIV pathogenesis, treatment and prevention. More recently, Australian clinicians and scientists have turned their attention to assisting other countries in developing effective responses, particularly within the Asia-Pacific region. It is therefore fitting that the 4th International AIDS Society (IAS Conference on HIV Pathogenesis, Treatment and Prevention will be held in Sydney in July 2007. The meeting is expected to attract over 5000 participants and will have a dynamic and innovative programme within the three major themes of HIV basic science, clinical research and biomedical prevention.

  19. Molecular epidemiology of imported cases of leishmaniasis in Australia from 2008 to 2014.

    Directory of Open Access Journals (Sweden)

    Tamalee Roberts

    Full Text Available Leishmaniasis is a vector borne disease caused by protozoa of the genus Leishmania. Human leishmaniasis is not endemic in Australia though imported cases are regularly encountered. This study aimed to provide an update on the molecular epidemiology of imported leishmaniasis in Australia. Of a total of 206 biopsies and bone marrow specimens submitted to St Vincent's Hospital Sydney for leishmaniasis diagnosis by PCR, 55 were found to be positive for Leishmania DNA. All PCR products were subjected to restriction fragment length polymorphism analysis for identification of the causative species. Five Leishmania species/species complexes were identified with Leishmania tropica being the most common (30/55. Travel or prior residence in a Leishmania endemic region was the most common route of acquisition with ~47% of patients having lived in or travelled to Afghanistan. Cutaneous leishmaniasis was the most common manifestation (94% with only 3 cases of visceral leishmaniasis and no cases of mucocutaneous leishmaniasis encountered. This report indicates that imported leishmaniasis is becoming increasingly common in Australia due to an increase in global travel and immigration. As such, Australian clinicians must be made aware of this trend and consider leishmaniasis in patients with suspicious symptoms and a history of travel in endemic areas. This study also discusses the recent identification of a unique Leishmania species found in native kangaroos and a potential vector host which could create the opportunity for the establishment of a local transmission cycle within humans.

  20. Struan Sutherland--Doyen of envenomation in Australia. (United States)

    Tibballs, James


    Struan Sutherland (1936-2002) was the doyen of medical research in the field of envenomation and the ultimate authority on the medical management of envenomated victims in Australia for almost 3 decades. In 1981 as Head of Immunology Research of Commonwealth Serum Laboratories (CSL), he produced an antivenom against the Sydney Funnel-web Spider (Atrax robustus)-an accomplishment that had defied numerous previous attempts. Struan also invented the pressure-immobilisation technique of first-aid for snake bite. This ingenious, simple but safe and effective technique revolutionised first-aid management of snake bite and of some other types of envenomation. It made redundant the use of tourniquets and other dangerous first-aid treatments. Similarly, he helped to develop a snake venom detection kit, which enables doctors working at a victim's bedside to ascertain which snake was responsible and which antivenom should be administered. He had a very wide range of research interests and was a prodigious researcher publishing over 200 scientific and medical articles, numerous chapters in books and the standard Australian medical textbook on the management of envenomation, Australian Animal Toxins. He made major contributions to the understanding of the venoms of Australia's remarkable range of fauna including snakes, spiders, Blue-ringed octopus, ants, jellyfish and stinging fish. Struan served the medical fraternity and the public selflessly. He was always available to doctors, or to anybody, to give advice at any hour of the day or night, on management of envenomated victims. Members of the Australian Venom Research Unit, which he founded in 1994 at The University of Melbourne, now continue this 24-h advisory service.

  1. A Multi-Site Study of Norovirus Molecular Epidemiology in Australia and New Zealand, 2013-2014 (United States)

    Lim, Kun Lee; Hewitt, Joanne; Sitabkhan, Alefiya; Eden, John-Sebastian; Lun, Jennifer; Levy, Avram; Merif, Juan; Smith, David; Rawlinson, William D.; White, Peter A.


    Background Norovirus (NoV) is the major cause of acute gastroenteritis across all age groups. In particular, variants of genogroup II, genotype 4 (GII.4) have been associated with epidemics globally, occurring approximately every three years. The pandemic GII.4 variant, Sydney 2012, was first reported in early 2012 and soon became the predominant circulating NoV strain globally. Despite its broad impact, both clinically and economically, our understanding of the fundamental diversity and mechanisms by which new NoV strains emerge remains limited. In this study, we describe the molecular epidemiological trends of NoV-associated acute gastroenteritis in Australia and New Zealand between January 2013 and June 2014. Methodology Overall, 647 NoV-positive clinical faecal samples from 409 outbreaks and 238 unlinked cases of acute gastroenteritis were examined by RT-PCR and sequencing. Phylogenetic analysis was then performed to identify NoV capsid genotypes and to establish the temporal dominance of circulating pandemic GII.4 variants. Recombinant viruses were also identified based on analysis of the ORF1/2 overlapping region. Findings Peaks in NoV activity were observed, however the timing of these epidemics varied between different regions. Overall, GII.4 NoVs were the dominant cause of both outbreaks and cases of NoV-associated acute gastroenteritis (63.1%, n = 408/647), with Sydney 2012 being the most common GII.4 variant identified (98.8%, n = 403/408). Of the 409 reported NoV outbreaks, aged-care facilities were the most common setting in both Western Australia (87%, n = 20/23) and New Zealand (58.1%, n = 200/344) while most of the NoV outbreaks were reported from hospitals (38%, n = 16/42) in New South Wales, Australia. An analysis of a subset of non-GII.4 viruses from all locations (125/239) showed the majority (56.8%, n = 71/125) were inter-genotype recombinants. These recombinants were surprisingly diverse and could be classified into 18 distinct recombinant

Specific criteria are set out by governments to ascertain the degree of risk and the need for government intervention. A study was undertaken to understand the current state of usage and the practice of naturopathy and western herbal medicine, and to ascertain whether statutory regulation was warranted. We found increased use of these complementary therapies in the community, with risks arising from both the specific practices as well as consumers negotiating a parallel primary health care system. We also found highly variable standards of training, a myriad of professional associations, and a general failure of current systems of self-regulation to protect public health and safety. Statutory regulation was the preferred policy response for consumers, insurers, general practitioners, and most of the complementary therapists. While we found a case for statutory registration, we also argue that a minimalist regulatory response needs to be accompanied by other measures to educate the public, to improve the standards of practice, and to enhance our understanding of the interaction between complementary and mainstream health care.Keywords: health workforce regulation, complementary health care, protection of

  3. Assessment of Natural Ventilation Potential for Residential Buildings across Different Climate Zones in Australia

    Full Text Available In this study, the natural ventilation potential of residential buildings was numerically investigated based on a typical single-story house in the three most populous climate zones in Australia. Simulations using the commercial simulation software TRNSYS (Transient System Simulation Tool were performed for all seasons in three representative cities, i.e., Darwin for the hot humid summer and warm winter zone, Sydney for the mild temperate zone, and Melbourne for the cool temperate zone. A natural ventilation control strategy was generated by the rule-based decision-tree method based on the local climates. Natural ventilation hour (NVH and satisfied natural ventilation hour (SNVH were employed to evaluate the potential of natural ventilation in each city considering local climate and local indoor thermal comfort requirements, respectively. The numerical results revealed that natural ventilation potential was related to the local climate. The greatest natural ventilation potential for the case study building was observed in Darwin with an annual 4141 SNVH out of 4728 NVH, while the least natural ventilation potential was found in the Melbourne case. Moreover, summer and transition seasons (spring and autumn were found to be the optimal periods to sustain indoor thermal comfort by utilising natural ventilation in Sydney and Melbourne. By contrast, natural ventilation was found applicable over the whole year in Darwin. In addition, the indoor operative temperature results demonstrated that indoor thermal comfort can be maintained only by utilising natural ventilation for all cases during the whole year, except for the non-natural ventilation periods in summer in Darwin and winter in Melbourne. These findings could improve the understanding of natural ventilation potential in different climates, and are beneficial for the climate-conscious design of residential buildings in Australia.

  5. Spatial mapping of lead, arsenic, iron, and polycyclic aromatic hydrocarbon soil contamination in Sydney, Nova Scotia: community impact from the coke ovens and steel plant. (United States)

    Lambert, Timothy W; Boehmer, Jennifer; Feltham, Jason; Guyn, Lindsay; Shahid, Rizwan


    This paper presents spatial maps of the arsenic, lead, and polycyclic aromatic hydrocarbon (PAH) soil contamination in Sydney, Nova Scotia, Canada. The spatial maps were designed to create exposure cohorts to help understand the observed increase in health effects. To assess whether contamination can be a proxy for exposures, the following hypothesis was tested: residential soils were impacted by the coke oven and steel plant industrial complex. The spatial map showed contaminants are centered on the industrial facility, significantly correlated, and exceed Canadian health risk-based soil quality guidelines. Core samples taken at 5-cm intervals suggest a consistent deposition over time. The concentrations in Sydney significantly exceed background Sydney soil concentrations, and are significantly elevated compared with North Sydney, an adjacent industrial community. The contaminant spatial maps will also be useful for developing cohorts of exposure and guiding risk management decisions.

  6. The economic viability of nuclear power in a fossil-fuel-rich country: Australia

    Energy Technology Data Exchange (ETDEWEB)

    Owen, Anthony


    This paper assesses the economic viability of investment in nuclear power generation in Australia and factors which may influence government policy towards such investments. It argues that the structure of the grid in Eastern Australia and the nature of the existing generator mix require nuclear technology that has similar attributes to combined cycle gas technology; i.e. modular construction of generating units, load following capability, low unit capital cost, and a general acceptance by the Australian public. The paper concludes that it is only Generation IV nuclear technology that has the potential to be part of Australia's energy mix after 2030.

    Australia, a major producer and user of coal, has the highest per capita greenhouse gas emissions in the industrialised world. This study investigates whether in theory such a 'fossil-fuel dependent' country could achieve a 50% reduction in CO{sub 2} emissions from stationary energy by 2040, compared with its 2001 emissions. To do this scenarios are developed, using a combination of forecasting and backcasting methods, under conditions of continuing economic growth and a restriction to the use of existing commercial technologies with small improvements. The principal scenario achieves the above target by implementing on the demand-side a medium-level of efficient energy use and substantial solar hot water together with a supply side combination of mainly natural gas, bioenergy and wind power. In doing so the scenario also achieves a 78% reduction in CO{sub 2} emissions from electricity. Within the large uncertainties in future prices, it is possible that the economic savings from efficient energy use could pay for all or a large part of the additional costs of renewable energy.

    M.A. Pérez Fernández


    Full Text Available Décadas de uso inadecuado de los recursos naturales en Australia han llevado a la extinción de numerosas especies autóctonas. Aprendiendo de sus propios errores, se han inicido recientemente diferentes proyectos de conservación en los que participan diversos agentes interesados. La Región de los Central Ranges, en el Desierto de Gibson, pertenece al pueblo aborigen Ngaanyatjarra. En los años 90 se llevó a cabo una campaña de recolección de organismos, patrocinada por el Museo de Western Australia y el Departamento de Conservación Ambiental (DEC, en la que participaron miembros de la comunidad Ngaanyatjarra, conocedores y cuidadores del territorio. El resultado científico se tradujo en la identificación de dos nuevas especies, así como numerosas nuevas citas de plantas y animales para el territorio. La minería es una de las actividades más impactantes en Australia, pero la concienciación social ha llevado a que las compañías desarrollen importantes campañas de protección de especies. El mulgara (Dasycercus cristicaula ocupaba zonas que hoy en día se dedican a la minería, y de las que prácticamente ha desaparecido. Un programa de investigación financiado por la empresa Resolute Resources y dirigido por el Departamento de Conservación y Manejo del Territorio (CALM ha permitido identificar poblaciones de este marsupial carnívoro y diseñar un programa de manejo cuyo objetivo es evitar actuaciones incompatibles con su actividad biológica. El resultado más relevante en ambas iniciativas ha sido la colaboración entre diferentes agentes implicados, con intercambio de conocimientos y experiencias. Especialmente importante ha sido la posibilidad de diseñar planes de manejo y actuación sobre el territorio, orientados a la preservación de valores naturales y culturales antiguos.

  9. Australia's marine virtual laboratory (United States)

    Proctor, Roger; Gillibrand, Philip; Oke, Peter; Rosebrock, Uwe


    In all modelling studies of realistic scenarios, a researcher has to go through a number of steps to set up a model in order to produce a model simulation of value. The steps are generally the same, independent of the modelling system chosen. These steps include determining the time and space scales and processes of the required simulation; obtaining data for the initial set up and for input during the simulation time; obtaining observation data for validation or data assimilation; implementing scripts to run the simulation(s); and running utilities or custom-built software to extract results. These steps are time consuming and resource hungry, and have to be done every time irrespective of the simulation - the more complex the processes, the more effort is required to set up the simulation. The Australian Marine Virtual Laboratory (MARVL) is a new development in modelling frameworks for researchers in Australia. MARVL uses the TRIKE framework, a java-based control system developed by CSIRO that allows a non-specialist user configure and run a model, to automate many of the modelling preparation steps needed to bring the researcher faster to the stage of simulation and analysis. The tool is seen as enhancing the efficiency of researchers and marine managers, and is being considered as an educational aid in teaching. In MARVL we are developing a web-based open source application which provides a number of model choices and provides search and recovery of relevant observations, allowing researchers to: a) efficiently configure a range of different community ocean and wave models for any region, for any historical time period, with model specifications of their choice, through a user-friendly web application, b) access data sets to force a model and nest a model into, c) discover and assemble ocean observations from the Australian Ocean Data Network (AODN, in a format that is suitable for model evaluation or data assimilation, and

  10. Energy research and development profile of Australia

    Energy Technology Data Exchange (ETDEWEB)

    Kenkeremath, L.


    Australia is a large, sparsely populated country with an economy based traditionally on raw materials exports. Though still a major international trader in minerals and agricultural products, Australia has suffered a decline in productivity, employment, exports, and economic growth since the 1950s. Most energy research and development (R and D) and policymaking activities are carried out under the National Energy Research, Development, and Demonstration (NERDD) program. The NERDD program priorities include, among others, production of liquid hydrocarbon fuels from natural gas or coal-derived synthesis gas and oil and gas exploration, assessment, and recovery technology (high priority); production of liquid fuels from coal and oil shale by hydrogenation or pyrolysis, coal gasification, and achievement of cost reductions in coal and oil shale exploration and assessment techniques (medium priority); and in-situ coal gasification (low priority). Bilateral agreements for energy R and D with other countries are carried out under the Australian Department of National Development and Energy. Australia currently has agreements related to oil, gas, shale, and coal liquids R and D with the UK, the US, Japan, and West Germany.

  11. Quarantine, exports and animal disease in Australia 1901-2010. (United States)

    Turner, Aj


    The Constitution forming the Australian Commonwealth Government on 1 January 1901 provided that animal and animal products imported into and exported from Australia would be under the authority of the national government. By mutual agreement, the Quarantine Act 1908 provided for the states to continue the delivery of services under contract until 1995 when the Commonwealth took back full responsibility for quarantine services. In the 1940s, 50s and 60s there were world pandemics of livestock diseases and Australia ceased the import of many species. By the 1970s, the livestock industries sought relaxation of import restrictions to gain access to diversified genetic stock. By the use of new technologies, many species can now be imported into Australia through tight importation protocols. With the advent of the World Trade Organization and implementation of the Sanitary Phytosanitary Agreement, Australia has developed a risk-based framework to support the development of import conditions for animals and animal products. Australia's 'Acceptable Level of Protection' has been set to provide a low likelihood of disease entry. Being an island continent, Australia can apply strong controls over imports and exports of all commodities and relatively few outbreaks of exotic animal diseases have occurred by breach of quarantine, but the outbreaks of rinderpest in 1923 and equine influenza in 2007 were notable exceptions.

  12. Has the ban on smoking in New South Wales restaurants worked? A comparison of restaurants in Sydney and Melbourne. (United States)

    Chapman, S; Borland, R; Lal, A


    To evaluate compliance with a legislative ban on smoking inside restaurants by comparing smoking in Sydney restaurants (where it is legally banned) with smoking in Melbourne restaurants (not subject to a legal ban). Unobtrusive observational study of restaurant patrons, and interviews with restaurant staff, carried out by 159 volunteers. 78 Sydney restaurants with smoke-free indoor environments (as required by legislation) and 81 Melbourne restaurants not subject to legislation preventing smoking. The study took place from 20-31 October 2000. Legislation to ban smoking in indoor areas of restaurants was introduced in New South Wales in September 2000 (about six weeks before our study). Observed incidents of smoking inside restaurants; staff attitudes to the ban; customer satisfaction as indicated by comments to staff; staff perceptions of restaurant patronage. No restaurant patrons were seen smoking in 78 Sydney restaurants during 156 hours of observation of 2,646 diners, compared with 176 smokers among 3,014 Melbourne diners over 154 hours of observation. Thirty-one per cent (24/78) of Sydney restaurants had experienced smokers attempting to smoke indoors after the legislation was introduced; 6% (5/78) reported instances of smokers refusing to stop smoking when asked; 79% (62/78) of restaurants had received favourable comments from patrons about the smoke-free law; 81% (63/78) of restaurant staff interviewed either supported or strongly supported the law. Since introduction of the legislation, 76% of restaurants reported normal trade, 14% increased trade, and 9% reduced trade. Smoke-free restaurants do not require "smoking police" to enforce bans, present few ongoing difficulties for staff, attract many more favourable than unfavourable comments from patrons, and do not adversely affect trade.

  14. Australia: historical earthquake studies

    Directory of Open Access Journals (Sweden)

    K. McCue


    Full Text Available Historical studies of earthquakes in Australia using information dating back to 1788 have been comprehensive, if not exhaustive. Newspapers have been the main source of historical earthquake studies. A brief review is given here with an introduction to the pre-European aboriginal dreamtime information. Some of the anecdotal information of the last two centuries has been compiled as isoseismal maps. Relationships between isoseismal radii and magnitude have been established using post-instrumental data allowing magnitudes to be assigned to the pre-instrumental data, which can then be incorporated into the national earthquake database. The studies have contributed to hazard analyses for the building codes and stimulated research into microzonation and paleo-seismology.

  16. Impacts of a measles outbreak in Western Sydney on public health resources. (United States)

    Flego, Kristina L; Belshaw, Daniel A; Sheppeard, Vicky; Weston, Kathryn M


    During February and March 2011, an outbreak of 26 confirmed cases of measles was reported to the Parramatta Public Health Unit (PHU) in western Sydney. This paper describes the impact of the outbreak on PHU resources. A retrospective review of information obtained from case notification forms and associated contact tracing records was carried out for each of the confirmed cases. Seven cases (27%) required hospital admission for more than 1 day and 10 (38%) cases required management within a hospital emergency department. There were no cases of encephalitis or death. The number of contacts was determined for each case as well as the number who required post-exposure prophylaxis. In total, 1,395 contacts were identified in this outbreak. Of these, 79 (5.7%) required normal human immunoglobulin and 90 (6.5%) were recommended to receive the measles-mumps-rubella vaccine. A case study detailing the PHU costs associated with the contact management of a hospitalised measles case with 75 identified contacts is also included and the estimated total cost to the PHU of containing this particular case of measles was A$2,433, with staff time comprising the major cost component. Considerable effort and resources are required to manage measles outbreaks. The total cost of this outbreak to the PHU alone is likely to have exceeded A$48,000.

  17. Palaeovalleys and protozoan assemblages in a late Carboniferous cyclotherm, Sydney Basin, Nova Scotia

    Energy Technology Data Exchange (ETDEWEB)

    Gibling, M.R.; Wightman, W.G. (Dalhousie University, Halifax, NS (Canada). Dept. of Earth Sciences)


    The early Stephanian Bonar Cyclotherm of the Sydney Basin, Nova Scotia, contains an erosional surface cut through coastal plain strata with economic coals and distributary channel bodies. The erosion surface is interpreted as a palaeovalley 20 m deep and at least 7 km wide that marks a sequence boundary formed during relative fall in sea level. The palaeovalley is filled with stacked alluvial channel bodies which become more isolated as the valley fill passes upward into red, alluvial plain deposits, probably laid down in an anastomosed river system. In an adjacent, interfluve area, calcretes and red, vertic palaeosols cap coastal strata. Assemblage analysis of agglutinated foraminifer and thecamoebians indicates that the palaeovalley was filled with freshwater sediments before an initial marine transgression flooded the alluvial surface and adjacent interfluve. Valley incision probably reflects glacioeustatic sea level fall. However, the alluvial nature of the valley deposits suggests that valley filling reflects an abundant sediment supply during lowstand and/or transgressive stages and was not a direct consequence of sea level rise. During the subsequent transgression phase, aggradation was rapid as sediment supply apparently kept pace with rising sea level. Features of both channel and extra-channel facies suggest that seasonality intensified during the transition from coastal plain to palaeovalley and alluvial plain deposition.

  18. Catering for the athletes village at the Sydney 2000 Olympic Games: the role of sports dietitians. (United States)

    Pelly, Fiona; O'Connor, Helen; Denyer, Gareth; Caterson, Ian


    This article describes the development, analysis, and implementation of the menu available to athletes and patrons in the main dining hall of the Athletes Village at the Sydney 2000 Olympic Games and the significant role of sports dietitians in this process. Menu design and development was informed by focus groups, literature reviews, and food-preference surveys of athletes. The final menu was also assessed by an expert panel of Australian sports dietitians. A custom-designed database (Foodweb) was developed to enable dietary analysis of food-production data and creation of point-of-choice nutrition labels. Dietitians assisted with quality assurance testing and training of catering staff. Athletes surveyed in the main dining hall (N=414) agreed that the menu contained sufficient variety and adequate meat, pasta/rice, vegetable/salad, fruit, and snack items. Sports dietitians played a significant role in ensuring that the menu met the needs of athletes from a range of differing cultural and sporting backgrounds. Dining-hall patrons provided positive feedback and few complaints about the overall dining experience. The information presented in this report can help future caterers and dietitians with the planning and provision of suitable food for athletic performance at an Olympic Games.

    Pai, Amy Shih-I; Wang, Jie Jin; Samarawickrama, Chameen; Burlutsky, George; Rose, Kathryn A; Varma, Rohit; Wong, Tien Yin; Mitchell, Paul


    To assess the prevalence and associations of visual impairment (VI) in preschool children. Cross-sectional, population-based study. A total of 2461 children (73.8% participation rate), aged 6 to 72 months, were examined in the Sydney Paediatric Eye Disease Study during 2007-2009; of whom 1188, aged 30 to 72 months, with complete visual acuity (VA) data in both eyes, were included in this report. Measurement of VA was attempted on all children using the Electronic Visual Acuity (EVA) system or a logarithm of the minimum angle of resolution (logMAR) chart. Visual impairment was defined as presenting VA 0.05). Visual impairment in at least 1 eye was found in 6.4% of Australian preschool children, with bilateral VI found in 2.7%. Uncorrected refractive errors and amblyopia were the principal ocular conditions associated with VI. Low birthweight was a significant risk factor independent of age, gender, and ethnicity.

  20. Spatial Interpolation of Daily Rainfall Data for Local Climate Impact Assessment over Greater Sydney Region

    Directory of Open Access Journals (Sweden)

    Xihua Yang


    Full Text Available This paper presents spatial interpolation techniques to produce finer-scale daily rainfall data from regional climate modeling. Four common interpolation techniques (ANUDEM, Spline, IDW, and Kriging were compared and assessed against station rainfall data and modeled rainfall. The performance was assessed by the mean absolute error (MAE, mean relative error (MRE, root mean squared error (RMSE, and the spatial and temporal distributions. The results indicate that Inverse Distance Weighting (IDW method is slightly better than the other three methods and it is also easy to implement in a geographic information system (GIS. The IDW method was then used to produce forty-year (1990–2009 and 2040–2059 time series rainfall data at daily, monthly, and annual time scales at a ground resolution of 100 m for the Greater Sydney Region (GSR. The downscaled daily rainfall data have been further utilized to predict rainfall erosivity and soil erosion risk and their future changes in GSR to support assessments and planning of climate change impact and adaptation in local scale.

  1. Observations of the pulsation of the Cepheid l Car with the Sydney University Stellar Interferometer

    CERN Document Server

    Davis, J; Robertson, J G; Ireland, M J; North, J R; Tango, W J; Tuthill, P G


    Observations of the southern Cepheid l Car to yield the mean angular diameter and angular pulsation amplitude have been made with the Sydney University Stellar Interferometer (SUSI) at a wavelength of 696 nm. The resulting mean limb-darkened angular diameter is 2.990+-0.017 mas (i.e. +-0.6 per cent) with a maximum-to-minimum amplitude of 0.560+-0.018 mas corresponding to 18.7+-0.6 per cent in the mean stellar diameter. Careful attention has been paid to uncertainties, including those in measurements, in the adopted calibrator angular diameters, in the projected values of visibility squared at zero baseline, and to systematic effects. No evidence was found for a circumstellar envelope at 696 nm. The interferometric results have been combined with radial displacements of the stellar atmosphere derived from selected radial velocity data taken from the literature to determine the distance and mean diameter of l Car. The distance is determined to be 525+-26 pc and the mean radius 169+-8R{solar). Comparison with pu...

  2. Ethnography From the Inside: Industry-based Research in the Commercial Sydney EDM Scene

    Directory of Open Access Journals (Sweden)

    Ed Montano


    Full Text Available Drawing on a decade of ethnographic research and participant observation in the Sydney commercial electronic dance music (EDM scene, this article explores some of the issues and tensions in conducting industry-based fieldwork in EDM culture. Through interviews with some of the scene’s key DJs, promoters, media workers and other industry personnel, consideration is given to designing a set of guiding principles for researchers undertaking “behind-the-scenes”, localised EDM research. The starting point for my discussion is my work in dance music retail, specifically at Central Station Records between 2002 and 2005. The level of access this work granted me to particular industry workers and the subsequent networks I was able to establish proved invaluable to my research not only when seeking out interviewees but also when seeking entry to clubs and events. However, while insider knowledge has numerous benefits, convincing contacts of the relevance of research can be problematic, as can maintaining a critical distance.

  3. Back to the future--the history and philosophy of medicine experiment at Sydney University. (United States)

    Cossart, Y E; Pegler, M A; Givney, R C


    History and Philosophy of Medicine has been a compulsory unit in the first year of the medical curriculum at Sydney University for the past decade. Volunteer tutors are drawn from most clinical and basic science departments, and each year the programme is organized on a theme of current importance in medical practice. This course began as an experiment because no resources were available for specialist staff, but has proved outstandingly successful in generating both student and teaching staff interest and support for the programme. Students present short tutorial papers to their peer group followed by submission of an essay which takes into account the tutorial discussion. The open book examination includes analysis of an unseen piece of primary source material as well as questions derived from the classwork. The Faculties of Arts and Science encouraged this educational experiment and several medical students have now opted to undertake a year of historical research during the intercalated B Sci(Med) programme, and a number of the tutors have enrolled in postgraduate historial or ethical programmes. We suggest that this model may permit introduction of novel courses in times of financial cutback within the Universities, and even allow a foundation to be laid for future development.

  4. Pioneering developments of marine renewable energy in Australia

    Directory of Open Access Journals (Sweden)

    Richard Manasseh


    Full Text Available The history of ocean renewable energy developments in Australia is reviewed. A layperson’s description of the physical operating principle is given for the main classes of technology that have been tested in Australian waters. The Australian marine domain possesses among the world’s most energetic wave-energy resources, driven by powerful mid-latitude westerly winds. The northern coast of Western Australia has tidal ranges significant on a global scale, and some geographical features around the continent have local tidal resonances. The East Australian Current, one of the world’s major western boundary currents, runs along the eastern Australian seaboard, offering potential for ocean-current energy. Sea-water temperatures in the tropical north-east of Australia may permit ocean thermal energy conversion. While this abundance of resources makes Australia an ideal location for technology development, the population is highly concentrated in a few large cities, and transmission infrastructure has developed over a century to supply cities from traditional power plants. Several wave-power developments have resulted in demonstration of deployments in Australian waters, three of which have been grid connected. Trials of tidal devices have also occurred, while other classes of ocean renewable energy have not yet been trialled. The prospects for marine renewable energy in Australia are discussed including non-traditional applications such as coastal protection and energy export.

  8. CO2 emissions from a temperate drowned river valley estuary adjacent to an emerging megacity (Sydney Harbour) (United States)

    Tanner, E. L.; Mulhearn, P. J.; Eyre, B. D.


    The Sydney Harbour Estuary is a large drowned river valley adjacent to Sydney, a large urban metropolis on track to become a megacity; estimated to reach a population of 10 million by 2100. Monthly underway surveys of surface water pCO2 were undertaken along the main channel and tributaries, from January to December 2013. pCO2 showed substantial spatio-temporal variability in the narrow high residence time upper and mid sections of the estuary, with values reaching a maximum of 5650 μatm in the upper reaches and as low as 173 μatm in the mid estuary section, dominated by respiration and photosynthesis respectively. The large lower estuary displayed less variability in pCO2 with values ranging from 343 to 544 μatm controlled mainly by tidal pumping and temperature. Air-water CO2 emissions reached a maximum of 181 mmol C m-2 d-1 during spring in the eutrophic upper estuary. After a summer high rainfall event nutrient-stimulated biological pumping promoted a large uptake of CO2 transitioning the Sydney Harbour Estuary into a CO2 sink with a maximum uptake of rate of -10.6 mmol C m-2 d-1 in the mid-section of the estuary. Annually the Sydney Harbour Estuary was heterotrophic and a weak source of CO2 with an air-water emission rate of 1.2-5 mmol C m-2 d-1 (0.4-1.8 mol C m-2 y-1) resulting in a total carbon emission of around 930 tonnes per annum. CO2 emissions (weighted m3 s-1 of discharge per km2 of estuary surface area) from Sydney Harbour were an order of magnitude lower than other temperate large tectonic deltas, lagoons and engineered systems of China, India, Taiwan and Europe but were similar to other natural drowned river valley systems in the USA. Discharge per unit area appears to be a good predictor of CO2 emissions from estuaries of a similar climate and geomorphic class.

  9. Migration from India to Australia. (United States)

    Awasthi, S P; Chandra, A


    "The article examines the contemporary trends and future prospects of migration from India to Australia. The focus is on Indian Settlers and Temporary Entrants admitted to Australia for employment and Indian students admitted to Australia for higher studies. The volume of emigration for permanent residence during the early 1990s has made India one of the leading source countries of migration to Australia. A majority of Indians admitted as Settlers every year join the labor force. Recent data indicate that, among Indian Settlers, there is a preponderance of unsponsored Independent Skilled Migrants. Given the anticipated growth in the number of Indian students, the coming years are likely to witness a spurt in Skilled Temporary Workers from India." excerpt

  14. Neutron scattering in Australia

    Energy Technology Data Exchange (ETDEWEB)

    Knott, R.B. [Australian Nuclear Science and Technology Organisation, Menai (Australia)


    Neutron scattering techniques have been part of the Australian scientific research community for the past three decades. The High Flux Australian Reactor (HIFAR) is a multi-use facility of modest performance that provides the only neutron source in the country suitable for neutron scattering. The limitations of HIFAR have been recognized and recently a Government initiated inquiry sought to evaluate the future needs of a neutron source. In essence, the inquiry suggested that a delay of several years would enable a number of key issues to be resolved, and therefore a more appropriate decision made. In the meantime, use of the present source is being optimized, and where necessary research is being undertaken at major overseas neutron facilities either on a formal or informal basis. Australia has, at present, a formal agreement with the Rutherford Appleton Laboratory (UK) for access to the spallation source ISIS. Various aspects of neutron scattering have been implemented on HIFAR, including investigations of the structure of biological relevant molecules. One aspect of these investigations will be presented. Preliminary results from a study of the interaction of the immunosuppressant drug, cyclosporin-A, with reconstituted membranes suggest that the hydrophobic drug interdigitated with lipid chains.

  15. The Going Out In Sydney App: Evaluating the Utility of a Smartphone App for Monitoring Real-World Illicit Drug Use and Police Encounters Among Festival and Club Goers

    Full Text Available Gaining accurate information on illicit drug use and policing in real-world settings is a challenge. This study examines the utility of a smartphone app (‘Going Out In Sydney’ to prospectively follow up illicit drug use and policing encounters at music festivals and licensed entertainment precincts in Sydney, Australia. In all, 38 regular festival and licensed entertainment venue attendees used the app to log nights out over a 3-month period, including (1 where they went (eg, festival, nightclub, (2 the prevalence of illicit drug use, and (3 the incidence and nature of police encounters. A survey and interview were then conducted about the utility of the app. The app enabled rich data collection (n = 353 entries about illicit drug use and policing at both target settings. Follow-up surveys indicated that most participants were extremely satisfied with the ease of use of the app and privacy afforded, and compared with other data collection modes, such as paper-based logs and online surveys, rated the app the most desirable method of data collection. This suggests smartphone apps may be a viable option for future studies on illicit drug use and policing of drugs.

  16. Indigenous actinorhizal plants of Australia

    Indian Academy of Sciences (India)

    Nishath K Ganguli; Ivan R Kennedy


    Indigenous species of actinorhizal plants of Casuarinaceae, Elaeagnaceae and Rhamnaceae are found in specific regions of Australia. Most of these plants belong to Casuarinaceae, the dominant actinorhizal family in Australia. Many of them have significant environmental and economical value. The other two families with their indigenous actinorhizal plants have only a minor presence in Australia. Most Australian actinorhizal plants have their native range only in Australia, whereas two of these plants are also found indigenously elsewhere. The nitrogen-fixing ability of these plants varies between species. This ability needs to be investigated in some of these plants. Casuarinas form a distinctive but declining part of the Australian landscape. Their potential has rarely been applied in forestry in Australia despite their well-known uses, which are being judiciously exploited elsewhere. To remedy this oversight, a programme has been proposed for increasing and improving casuarinas that would aid in greening more regions of Australia, increasing the soil fertility and the area of wild life habitat (including endangered species). Whether these improved clones would be productive with local strains of Frankia or they need an external inoculum of Frankia should be determined and the influence of mycorrhizal fungi on these clones also should be investigated.

    Full Text Available OBJECTIVES: Pulse wave velocity (PWV is a measure of arterial stiffness and its increase with ageing has been associated with damage to cerebral microvessels and cognitive impairment. This study examined the relationship between carotid-femoral PWV and specific domains of cognitive function in a non-demented elderly sample. METHOD: Data were drawn from the Sydney Memory and Ageing Study, a cohort study of non-demented community-dwelling individuals aged 70-90 years, assessed in successive waves two years apart. In Wave 2, PWV and cognitive function were measured in 319 participants. Linear regression was used to analyse the cross-sectional relationship between arterial stiffness and cognitive function in the whole sample, and separately for men and women. Analysis of covariance was used to assess potential differences in cognition between subjects with PWV measurements in the top and bottom tertiles of the cohort. Covariates were age, education, body mass index, pulse rate, systolic blood pressure, cholesterol, depression, alcohol, smoking, hormone replacement therapy, apolipoprotein E ε4 genotype, use of anti-hypertensive medications, history of stroke, transient ischemic attack, myocardial infarction, angina, diabetes, and also sex for the whole sample analyses. RESULTS: There was no association between PWV and cognition after Bonferroni correction for multiple testing. When examining this association for males and females separately, an association was found in males, with higher PWV being associated with lower global cognition and memory, however, a significant difference between PWV and cognition between males and females was not found. CONCLUSION: A higher level of PWV was not associated with lower cognitive function in the whole sample.

  19. Residential age care and domiciliary oral health services: Reach-OHT-The development of a metropolitan oral health programme in Sydney, Australia. (United States)

    Wright, F A Clive; Law, Garry; Chu, Steven K-Y; Cullen, John S; Le Couteur, David G


    To describe an oral health care programme for older people in Residential Aged Care Facilities (RACFs) to improve access to care and support facilities. Different models of residential care have been proposed, but few have been comprehensive (providing on-site health promotion and service delivery) or sustainable. A partnership model of oral health care, with dental services plus oral health education, was integrated into the community outreach services of a metropolitan hospital department of aged care. The programme provided annual oral health education and training to staff, and on-site dental care to 10 (RACFs). None of the RACFs had received organised education or on-site dental service care prior to the programme. At the completion of the third year of the programme, 607 residents (75% of the total bed capacity for the 10 RACFs) had received an annual oral health assessment, and 271 (46.5%) had received on-site dental care. More than 120 nursing and allied health staff had received education and training in oral health support to residents. Oral cleanliness, the proportion not experiencing dental pain and referral for additional care decreased significantly over the period, but dental caries experience and periodontal conditions remained a concern. Sustainable domiciliary oral health services and oral health education are feasible and practical using a partnership model within the Australian health system. Adaptability, continuity and the use of oral health therapists/dental hygienists in the coordination and management of the programme further contribute to viability. © 2017 The Authors.

  20. The use of vintage surficial sediment data and sedimentary cores to determine past and future trends in estuarine metal contamination (Sydney estuary, Australia). (United States)

    Birch, G F; Chang, C-H; Lee, J-H; Churchill, L J


    The objectives of the present investigation were to determine past trends in sediment contamination and possibly predict future trends. Multiple vintages of surficial sediment metal data, from a quasi-decadal 'Status and Trends' programme, were used to provide large-scale spatial information on current status and temporal change. This information was augmented by sediment cores, specifically located to verify surface sediment data and to determine trends at major points of stormwater discharge. The data obtained indicate that surficial sediment metal concentrations have declined, since about the early 1990s, in extensive parts of the upper and central estuaries and have increased slightly in the lower estuary, due mainly to a down-estuary shift in industry and urbanisation. Declining surficial sediment metal concentrations is due to a movement of industry out of the catchment, especially from foreshore areas and the introduction of regulation, which prevent pollutants being discharged directly to the estuary. The major present-day source of metals is stormwater, with minor inputs from the main estuary channel into embayments and runoff from previously contaminated mainland sites. Modelled relaxation rates are optimistic as high metal concentrations in stormwater will slow predicted rates. Stormwater remediation should be the main managerial focus for this estuary. Multiple vintages of surficial sediment metal data covering the past 30 years, supplemented by sedimentary core data, have allowed past and future contamination trends to be determined. This type of science-based information provides an important tool for strategic management of this iconic waterway.

  1. Emergency department visits, ambulance calls, and mortality associated with an exceptional heat wave in Sydney, Australia, 2011: a time-series analysis

    Directory of Open Access Journals (Sweden)

    Schaffer Andrea


    Full Text Available Abstract Background From January 30-February 6, 2011, New South Wales was affected by an exceptional heat wave, which broke numerous records. Near real-time Emergency Department (ED and ambulance surveillance allowed rapid detection of an increase in the number of heat-related ED visits and ambulance calls during this period. The purpose of this study was to quantify the excess heat-related and all-cause ED visits and ambulance calls, and excess all-cause mortality, associated with the heat wave. Methods ED and ambulance data were obtained from surveillance and administrative databases, while mortality data were obtained from the state death registry. The observed counts were compared with the average counts from the same period from 2006/07 through 2009/10, and a Poisson regression model was constructed to calculate the number of excess ED visits, ambulance and deaths after adjusting for calendar and lag effects. Results During the heat wave there were 104 and 236 ED visits for heat effects and dehydration respectively, and 116 ambulance calls for heat exposure. From the regression model, all-cause ED visits increased by 2% (95% CI 1.01-1.03, all-cause ambulance calls increased by 14% (95% CI 1.11-1.16, and all-cause mortality increased by 13% (95% CI 1.06-1.22. Those aged 75 years and older had the highest excess rates of all outcomes. Conclusions The 2011 heat wave resulted in an increase in the number of ED visits and ambulance calls, especially in older persons, as well as an increase in all-cause mortality. Rapid surveillance systems provide markers of heat wave impacts that have fatal outcomes.

  2. Drug use and risk behaviours among injecting drug users: a comparison between sex workers and non-sex workers in Sydney, Australia

    Directory of Open Access Journals (Sweden)

    Breen Courtney


    Full Text Available Abstract Background This paper examines the differences in demographics, drug use patterns and self reported risk behaviours between regular injecting drug users (IDU who report engaging in sex work for money or drugs and regular injecting drug users who do not. Methods Cross sectional data collected from regular IDU interviewed as part of the New South Wales (NSW Illicit Drug Reporting System (IDRS in 2003 were analysed. Results IDU who reported engaging in sex work were more likely to be female, and identify as being of Aboriginal and/or Torres Strait Islander descent. They initiated injecting drug use at a significantly younger age and were more likely to report injection related problems than IDU who had not engaged in sex work. There were no differences in the drug classes used, but findings suggested that the sex workers tended to be more frequent users of crystalline methamphetamine (ice and benzodiazepines. Conclusion The similarities between these groups were more striking than the differences. Further research, examining a larger sample is needed to clarify whether injecting drug users who are sex workers have heavier use patterns.

    Norris, Jacqueline M; Bell, Erin T; Hales, Louise; Toribio, Jenny-Ann L M L; White, Joanna D; Wigney, Denise I; Baral, Randolph M; Malik, Richard


    Serum samples from 340 pet cats presented to three inner city clinics in Sydney Australia, 68 feral cats from two separate colonies in Sydney, and 329 cattery-confined pedigree and domestic cats in eastern Australia, were collected over a 2-year period and tested for antibodies directed against feline immunodeficiency virus (FIV) using immunomigration (Agen FIV Rapid Immunomigration test) and enzyme-linked immunosorbent assay methods (Snap Combo feline leukaemia virus antigen/FIV antibody test kit, IDEXX Laboratories). Western blot analysis was performed on samples in which there was discrepancy between the results. Information regarding breed, age, gender, housing arrangement and health status were recorded for all pet and cattery-confined cats, while the estimated age and current physical condition were recorded for feral cats. The FIV prevalence in the two feral cat populations was 21% and 25%. The majority of FIV-positive cats were male (60-80%). The FIV prevalence in cattery-confined cats was nil. The prevalence of FIV in the pet cat sample population was 8% (27/340) with almost equal prevalence in 'healthy' (13/170) and 'systemically unwell' (14/170) cats. The age of FIV-positive pet cats ranged from 3 to 19 years; all FIV-positive cats were domestic shorthairs with outside access. The median age of FIV-positive pet cats (11 years) was significantly greater than the median age of FIV-negative pet cats (7.5 years: Pcats (21/172; 12%) was three times that in female pet cats (6/168; 4%; Pcat population given outside access and continued FIV infection present in the feral population, this study highlights the need to develop rapid, accurate and cost-effective diagnostic methods that are not subject to false positives created by concurrent vaccination against FIV. This is especially important in re-homing stray cats within animal shelters and monitoring the efficacy of the new vaccine, which has not been challenged against Australian strains.

  4. Sustained outbreak of measles in New South Wales, 2012: risks for measles elimination in Australia

    Directory of Open Access Journals (Sweden)

    Zeina Najjar


    Full Text Available Objective: On 7 April 2012, a recently returned traveller from Thailand to Australia was confirmed to have measles. An outbreak of measles subsequently occurred in the state of New South Wales, prompting a sustained and coordinated response by public health authorities. The last confirmed case presented on 29 November 2012. This report describes the outbreak and its characteristics. Methods: Cases were investigated following Australian protocols, including case interviews and assessment of contacts for post-exposure prophylaxis. Results: Of the 168 cases identified, most occurred in south-western and western Sydney (92.9%, n = 156. Notable features of this outbreak were the disproportionately high number of cases in the 10–19-year-old age group (29.2%, n = 49, the overrepresentation among people of Pacific Islander descent (21.4%, n = 36 and acquisition in health-care facilities (21.4%, n = 36. There were no reported cases of encephalitis and no deaths. Discussion: This was the largest outbreak of measles in Australia since 1997. Its occurrence highlights the need to maintain vigilant surveillance systems for early detection and containment of measles cases and to maintain high population immunity to measles through routine childhood immunization. Vaccination campaigns targeting susceptible groups may also be necessary to sustain Australia’s measles elimination status.

  5. Perceived acculturative stress and sense of coherence in Chinese nursing students in Australia. (United States)

    He, Flora X; Lopez, Violeta; Leigh, Maria C


    University schools of nursing in Australia are the main providers of nursing education programmes for international students. The large cohort of overseas students requires that universities, as education providers, understand their needs and the problems related to studying and living in Australia. An exploratory descriptive quantitative study was conducted to investigate 119 Chinese international undergraduate nursing students' acculturative stress and sense of coherence at an Australian university in Sydney. Two validated scales were used: Acculturative Stress Scale for International Students (ASSIS) and Sense of Coherence (SOC). Results indicated that overall Chinese nursing students had a moderate level of acculturative stress and sense of coherence. However, there was a significant difference in the level of acculturative stress among three groups of Chinese nursing students enrolled in the Bachelor of Nursing course, and SOC was negatively correlated with the level of acculturative stress. This study extends the knowledge of the experiences of Chinese nursing students studying and living in an English-speaking country. The study also highlights the need for universities to provide relevant support to overseas students to make their study journey smoother and more successful.

  6. New species of Mycosphaerella from Myrtaceae in plantations and native forests in eastern Australia. (United States)

    Carnegie, Angus J; Burgess, Treena I; Beilharz, Vyrna; Wingfield, Michael J


    The majority of Mycosphaerella species from eucalypts (Eucalyptus, Corymbia and Angophora) in Australia have been recorded only from trees growing in plantations. This illustrates a bias in research in the past two decades toward commercial enterprise, and it emphasises a lack of understanding of the occurrence of these important fungi under natural conditions. Surveys of foliar fungi in native forests in eastern Australia, as well as adjacent plantations, thus have been initiated in recent years. In this study we describe four new species of Mycosphaerella from Eucalyptus spp. as well as other Myrtaceae. Mycosphaerella tumulosa sp. nov. (anamorph: Pseudocercospora sp.) was found on more than seven species of Eucalyptus and Corymbia in native forests and plantations in northeastern New South Wales and southeastern Queensland and appears to be relatively common, although not damaging to these trees. Mycosphaerella multiseptata sp. nov. was recorded from several locations on species of Angophora in native forests and amenity plantings. Mycosphaerella pseudovespa sp. nov. was found in one location in native forest on E. biturbinata. The first species of Mycosphaerella to be described from Syncarpia, M. syncarpiae sp. nov., was found in native forests in numerous locations from Sydney through to northeastern New South Wales and appears to be relatively common.

    Full Text Available Cities are frequently experiencing artificial heat stress, known as the Urban Heat Island (UHI effect. The UHI effect is commonly present in cities due to increased urbanization, where anthropogenic heat and human modifications have altered the characteristics of surfaces and atmosphere. Urban structure, land cover and metabolism are underlined as UHI key contributors and can result in higher urban densities being up to 10°C hotter compared to their peri-urban surroundings. The UHI effect increases the health-risk of spending time outdoors and boosts the need for energy consumption, particularly for air-conditioning during summer. Under investigation is what urban features are more resilient to the surface layer Urban Heat Island (sUHI effect in precinct scale. In the context of Sydney, this ongoing research aims to explore the most heat resilient urban features at precinct scale. This UHI investigation covers five highdensity precincts in central Sydney and is based on a nocturnal remote-sensing thermal image of central Sydney taken on 6 February 2009. Comparing the surface temperature of streetscapes and buildings’ rooftops (dominant urban horizontal surfaces, indicates that open spaces and particularly streetscapes are the most sensitive urban elements to the sUHI effect. The correlations between street network intensity, open space ratio, urban greenery ratio and the sUHI effect is being analysed in Sydney’s high-density precincts. Results indicate that higher open space ratio and street network intensity correlate significantly to higher sUHI effect at precinct scale. Meanwhile, 10% increase in the urban greenery can effectively decrease the precinct temperature by 0.6°C.

  9. The Impacts of Household Financial Stress, Resilience, Social Support, and Other Adversities on the Psychological Distress of Western Sydney Parents

    Directory of Open Access Journals (Sweden)

    Melanie Taylor


    Full Text Available This study investigated the prevalence of psychological distress among parents in Western Sydney households and examined its relationship with household financial, family and life stressors, and potential resilience factors. As part of a longer-term study, parents from Western Sydney, New South Wales (NSW, completed computer-assisted telephone interviews (CATI in May 2011 (N=439. Respondents were primary caregivers of at least one child (aged 4–16. Responses were weighted to reflect the Western Sydney population. Multivariate analyses were conducted to examine the relationship between parent experiences of stressor and resilience factors and reported psychological distress. Overall, 10.7% (95% CI: 7.8, 14.5 reported experiencing high/very high levels of psychological distress. Multivariate analysis indicated that financial hardship factors formed the strongest associations with psychological distress particularly housing and job security factors and, specifically, inability to meet mortgage/rent payments (OR=5.15, 95% CI: 1.74–15.25, p=0.003, poor self-rated health (OR=4.48, 95% CI: 1.88–10.64, p=0.001, adult job loss (OR=3.77, 95% CI: 1.33–10.66, p=0.013, and other family/life events (OR=2.30, 95% CI: 1.05–5.03, p=0.037. High personal resilience was common within this parent population and was a significant protective factor for high psychological distress (OR=0.14, 95% CI: 0.06–0.34, p<0.001. The findings support the development of targeted interventions to promote parent coping strategies in the context of household financial hardship.

    Duffield, P H; Duffield, A M; Carroll, P R; Morgans, D


    Thirteen compounds have been identified using gas chromatography mass spectrometry in the venom of the Sydney funnel-web spider, Atrax robustus. The compounds were identified as their trimethylsilyl or pentafluoropropionate derivatives and were citric acid, lactic acid, phosphoric acid, glycerol, urea, glucose, gamma-aminobutyric acid, glycine, spermidine, spermine, tyramine and octopamine. Female venom contained trace quantities of 5-methyoxytryptamine which was not detected in male venom. Quantitative determination of tyramine and octopamine was achieved using chemical ionization (CH4) gas chromatography mass spectrometry and deuterated internal standards.

  12. Review of Australia's polio surveillance. (United States)

    Paterson, Beverley J; Durrheim, David N


    With eradication almost within reach, the importance of detecting every poliomyelitis case has taken on additional significance. The selected surveillance strategy must be effective and efficient. A review of polio surveillance in Australia was conducted to consider whether current strategies were optimal. Document review and semi-structured key informant interviews were used to conduct the review. Interviews were recorded, transcribed and thematically analysed. The review was an iterative process with feedback on the findings sought from interviewees. Since Western Pacific Regional polio-elimination status was certified, one imported adult case was detected in 2007 in Australia, with no evidence of further transmission, and no Australian paediatric cases identified. Respondents reported that: it was not possible to prevent importations; paediatric cases were more likely to be identified than adult cases; and there may be a low level of suspicion among clinicians. Case detection and outbreak mitigation were considered key reasons to undertake polio surveillance. While Australia has not achieved one of the key World Health Organization (WHO) surveillance targets, this did not compromise Australias polio-free status. Identified issues with polio surveillance were the potential for an importation with high attendant investigation and containment costs, low stool sample collection rates, and the opportunity to improve safeguards around the importation and laboratory storage of biological samples containing poliovirus. The review found strong support for ongoing polio surveillance, particularly to detect imported cases and to demonstrate commitment to maintaining a polio-free region. Existing polio surveillance strategies were considered appropriate for Australia.

  13. Spatial and temporal distribution and pollution assessment of trace metals in marine sediments in Oyster Bay, NSW, Australia. (United States)

    Alyazichi, Yasir M; Jones, Brian G; McLean, Errol


    The disposal of untreated urban and industrial wastewater has a deleterious effect on both the water and sediment quality of Oyster Bay located in south Sydney, Australia. The present investigation was undertaken to evaluate the potential pollution of marine sediments in Oyster Bay. The results of metals were compared with adverse biological effect values effect range low (ERL) and effect range median (ERM). Spatial distribution of trace metals was estimated by applying geographic information system. The results indicated that the sediments were polluted with Cu, Zn, As and Pb, which exceeded ERL levels. However, these metals were still below ERM values, and other metals Cr and Ni were below ERL. Moreover, the highest concentrations of metals were around discharge points and in the inner bay. Further, trace metals could be attributed to human activities within the bay as they declined in concentrations with increasing sediment depth.

  16. An odyssey of environmental pollution: the rise, fall and remobilization of industrial lead in Australia (United States)

    Taylor, M. P.; Kristensen, L.; Liqin, W.; Harvey, P. J.; Dong, C.; Rouillon, M.


    The use of lead in automobile gasoline resulted in more than 240,000 tonnes of lead being emitted to the Australian environment over its 70-year period of use starting in 1932. The consequences of the emissions and subsequent depositions have resulted in marked contamination of urban and peri-urban aerosols, soils, plants and humans. This paper charts these effects and examines the extent of recovery from one of the most pervasive and persistent environmental pollutants. Lead isotopic composition of Adelaide and Sydney aerosol filters show that air lead composition shifts from values that approximate Broken Hill type ores, the predominant lead source used in gasoline (1.04 206Pb/207Pb and 2.31 208Pb/207Pb), towards ratios that more closely match local uncontaminated soil and bedrock values (Adelaide ~1.19 206Pb/207Pb and ~2.50 208Pb/207Pb; Sydney ~1.15 206Pb/207Pb and 2.48 208Pb/207Pb). Proxy atmospheric measurements from historic wine, lichen and fungi samples extending over 120 years show how both concentration and composition values shifted in the middle to late 20th century to reflect petrol emissions and then recovered rapidly at the end of the century as leaded gasoline consumption declined. For example, lead in wine from South Australia fell from >100 μg/L in the 1960s and 1970s to industrial lead and other toxic metals (including arsenic, cadmium and nickel) are subject to frequent remobilization. Predicted increases in wildfires and the generation of lead, arsenic and cadmium toxic particulates warrants greater consideration of the risk for vulnerable populations and firefighters who are most exposed.

  17. Mechanistic insights into induction of vitellogenin gene expression by estrogens in Sydney rock oysters, Saccostrea glomerata. (United States)

    Tran, Thi Kim Anh; MacFarlane, Geoff R; Kong, Richard Yuen Chong; O'Connor, Wayne A; Yu, Richard Man Kit


    Marine molluscs, such as oysters, respond to estrogenic compounds with the induction of the egg yolk protein precursor, vitellogenin (Vtg), availing a biomarker for estrogenic pollution. Despite this application, the precise molecular mechanism through which estrogens exert their action to induce molluscan vitellogenesis is unknown. As a first step to address this question, we cloned a gene encoding Vtg from the Sydney rock oyster Saccostrea glomerata (sgVtg). Using primers designed from a partial sgVtg cDNA sequence available in Genbank, a full-length sgVtg cDNA of 8498bp was obtained by 5'- and 3'-RACE. The open reading frame (ORF) of sgVtg was determined to be 7980bp, which is substantially longer than the orthologs of other oyster species. Its deduced protein sequence shares the highest homology at the N- and C-terminal regions with other molluscan Vtgs. The full-length genomic DNA sequence of sgVtg was obtained by genomic PCR and genome walking targeting the gene body and flanking regions, respectively. The genomic sequence spans 20kb and consists of 30 exons and 29 introns. Computer analysis identified three closely spaced half-estrogen responsive elements (EREs) in the promoter region and a 210-bp CpG island 62bp downstream of the transcription start site. Upregulation of sgVtg mRNA expression was observed in the ovaries following in vitro (explants) and in vivo (tank) exposure to 17β-estradiol (E2). Notably, treatment with an estrogen receptor (ER) antagonist in vitro abolished the upregulation, suggesting a requirement for an estrogen-dependent receptor for transcriptional activation. DNA methylation of the 5' CpG island was analysed using bisulfite genomic sequencing of the in vivo exposed ovaries. The CpG island was found to be hypomethylated (with 0-3% methylcytosines) in both control and E2-exposed oysters. However, no significant differential methylation or any correlation between methylation and sgVtg expression levels was observed. Overall, the

    Hale, B. [Guelph Univ., ON (Canada). Dept. of Land Resource Science


    The concentration of various metals in the fruit harvested from Lowbush blueberry plants in Whitney Pier, Sydney, Nova Scotia (NS), North Sydney (NS) and supermarket were quantified in this report. The concentrations were compared among the 3 sources to determine whether the metal and Polycyclic Aromatic Hydrocarbons (PAHs) concentrations in the blueberries from Whitney Pier were higher or lower compared to the reference blueberries from North Sydney and the supermarket. Mean values for each of the analytes were compared using analysis of variance (ANOVA). The study determined whether washed berries have lower concentrations of contaminants than unwashed berries. The risk to human health of exposure to metals and PAHs through consumption of blueberry samples was also calculated. It was concluded that concentrations of selenium and zinc are elevated in blueberries from Whitney Pier compared to berries from North Sydney and the supermarket, but are well within safe levels. Other elements such as arsenic, titanium, vanadium, lead, copper and molybdenum were similar, and only thallium was elevated in supermarket berries relative to those from Whitney Pier and North Sydney. Chromium was not detected in any samples. It was determined that there was no risk to human health from exposure to any of the metals analyzed, regardless of whether they were Whitney Pier samples or reference samples. Only 2 PAHs were detected in one of the unwashed samples from Whitney Pier. No PAHs were found in washed berries or unwashed berries from the supermarket or North Sydney. It was concluded that there was no risk to human health from exposure to any of the PAHs. Washed and unwashed samples had similar metal concentrations, indicating that surface contamination did not occur. A full methodology of the testing program was provided. 11 refs., 7 tabs., 2 figs.

  19. Remembering the Battle for Australia

    Full Text Available For the last two years, Australia has commemorated, on the first Wednesday in September, the ‘Battle for Australia Day’, to mark the role of Australian forces fighting the Japanese in the Pacific in WWII. The aim of this article is to identify the agents involved in the campaign for the gazetting of this day and the justifications advanced; to trace the conflicting narratives and political and historical controversies surrounding the notion of a ‘Battle for Australia’; and to outline the shifts in domestic and international politics and generational change that provide the context for the inauguration of this day.

  20. Evidence for a high molecular weight pre-robustoxin molecule in the venom of the male Sydney funnel-web spider (Atrax robustus). (United States)

    Collins, S P; Comis, A; Tyler, M I; Marshall, M; Howden, M E


    Robustoxin is the lethal polypeptide toxin in Atrax robustus venom. A monoclonal antibody was produced using synthetic, unfolded robustoxin conjugated to keyhole limpet haemocyanin as the immunogen. This monoclonal antibody did not protect newborn mice against challenge with the crude venom of the male Sydney funnel-web spider, but did slightly prolong their survival time. Western blotted crude venom of the male Sydney funnel-web spider showed two monoclonal antibody binding bands. One band at low M(r) corresponded to robustoxin (M(r) 4854), while the other higher M(r) band (approximately 37,000) may be due to a pre-robustoxin molecule.

  1. Differential proteomic responses of selectively bred and wild-type Sydney rock oyster populations exposed to elevated CO2. (United States)

    Thompson, E L; O'Connor, W; Parker, L; Ross, P; Raftos, D A


    Previous work suggests that larvae from Sydney rock oysters that have been selectively bred for fast growth and disease resistance are more resilient to the impacts of ocean acidification than nonselected, wild-type oysters. In this study, we used proteomics to investigate the molecular differences between oyster populations in adult Sydney rock oysters and to identify whether these form the basis for observations seen in larvae. Adult oysters from a selective breeding line (B2) and nonselected wild types (WT) were exposed for 4 weeks to elevated pCO2 (856 μatm) before their proteomes were compared to those of oysters held under ambient conditions (375 μatm pCO2 ). Exposure to elevated pCO2 resulted in substantial changes in the proteomes of oysters from both the selectively bred and wild-type populations. When biological functions were assigned, these differential proteins fell into five broad, potentially interrelated categories of subcellular functions, in both oyster populations. These functional categories were energy production, cellular stress responses, the cytoskeleton, protein synthesis and cell signalling. In the wild-type population, proteins were predominantly upregulated. However, unexpectedly, these cellular systems were downregulated in the selectively bred oyster population, indicating cellular dysfunction. We argue that this reflects a trade-off, whereby an adaptive capacity for enhanced mitochondrial energy production in the selectively bred population may help to protect larvae from the effects of elevated CO2 , whilst being deleterious to adult oysters. © 2015 John Wiley & Sons Ltd.

  2. Histologic Evaluation of Gastric Biopsies According to Sydney Classification and Comparison of Chronic Gastritis Mucosal Histological Findings by Age Group

    Full Text Available The aim of this study is to evaluate the materials of gastric biopsies in cases diagnosed as chronic gastritis according to the Sydney system and to compare the parameters according to age groups. The Sydney system of gastritis has five main histological features of changes in gastric mucosa graded (chronic inflammation, neutrophil activity, glandular atrophy, intestinal metaplasia and Helicobacter pylori density In our study, we evaluated 63 patients under 31 years, 177 patients between the ages of 31-60 and 187 patients over 61 years, who were diagnosed as having chronic gastritis by endoscopic biopsy. In 31-60 age group, the localization of Helicobacter pylori was often the antrum. In contrast, in the under 31 years of age group, Helicobacter pylori infection were found to be in the form of the distribution pangastrit. Acute inflammation in the under31 years group was found to be significantly higher than other age groups. In over 61years group, high incidence of atrophy was found. In our study, we detected the rate in atrophy and intestinal metaplasia with Helicobacter pylori is independently increased with age. [J Contemp Med 2012; 2(3.000: 173-178

  3. High variation in manufacturer-declared serving size of packaged discretionary foods in Australia. (United States)

    Despite the potential of declared serving size to encourage appropriate portion size consumption, most countries including Australia have not developed clear reference guidelines for serving size. The present study evaluated variability in manufacturer-declared serving size of discretionary food and beverage products in Australia, and how declared serving size compared with the 2013 Australian Dietary Guideline (ADG) standard serve (600 kJ). Serving sizes were obtained from the Nutrition Information Panel for 4466 packaged, discretionary products in 2013 at four large supermarkets in Sydney, Australia, and categorised into fifteen categories in line with the 2013 ADG. For unique products that were sold in multiple package sizes, the percentage difference between the minimum and the maximum serving size across different package sizes was calculated. A high variation in serving size was found within the majority of food and beverage categories - for example, among 347 non-alcoholic beverages (e.g. soft drinks), the median for serving size was 250 (interquartile range (IQR) 250, 355) ml (range 100-750 ml). Declared serving size for unique products that are available in multiple package sizes also showed high variation, particularly for chocolate-based confectionery, with median percentage difference between minimum and maximum serving size of 183 (IQR 150) %. Categories with a high proportion of products that exceeded the 600 kJ ADG standard serve included cakes and muffins, pastries and desserts (≥74 % for each). High variability in declared serving size may confound interpretation and understanding of consumers interested in standardising and controlling their portion selection. Future research is needed to assess if and how standardising declared serving size might affect consumer behaviour.

  4. Building healthy bones throughout life: an evidence-informed strategy to prevent osteoporosis in Australia. (United States)

    Ebeling, Peter R; Daly, Robin M; Kerr, Deborah A; Kimlin, Michael G


    Osteoporosis imposes a tremendous burden on Australia: 1.2 million Australians have osteoporosis and 6.3 million have osteopenia. In the 2007–08 financial year, 82 000 Australians suffered fragility fractures, of which > 17 000 were hip fractures. In the 2000–01 financial year, direct costs were estimated at $1.9 billion per year and an additional $5.6 billion on indirect costs. Osteoporosis was designated a National Health Priority Area in 2002; however, implementation of national plans has not yet matched the rhetoric in terms of urgency. Building healthy bones throughout life, the Osteoporosis Australia strategy to prevent osteoporosis throughout the life cycle, presents an evidence-informed set of recommendations for consumers, health care professionals and policymakers. The strategy was adopted by consensus at the Osteoporosis Australia Summit in Sydney, 20 October 2011. Primary objectives throughout the life cycle are: to maximise peak bone mass during childhood and adolescence to prevent premature bone loss and improve or maintain muscle mass, strength and functional capacity in healthy adults to prevent and treat osteoporosis in order to minimise the risk of suffering fragility fractures, and reduce falls risk, in older people. The recommendations focus on three affordable and important interventions — to ensure people have adequate calcium intake, vitamin D levels and appropriate physical activity throughout their lives. Recommendations relevant to all stages of life include: daily dietary calcium intakes should be consistent with Australian and New Zealand guidelines serum levels of vitamin D in the general population should be above 50nmol/L in winter or early spring for optimal bone health regular weight-bearing physical activity, muscle strengthening exercises and challenging balance/mobility activities should be conducted in a safe environment.

  5. Regime shifts in annual maximum rainfall across Australia - implications for intensity-frequency-duration (IFD) relationships (United States)

    Verdon-Kidd, D. C.; Kiem, A. S.


    Rainfall intensity-frequency-duration (IFD) relationships are commonly required for the design and planning of water supply and management systems around the world. Currently, IFD information is based on the "stationary climate assumption" that weather at any point in time will vary randomly and that the underlying climate statistics (including both averages and extremes) will remain constant irrespective of the period of record. However, the validity of this assumption has been questioned over the last 15 years, particularly in Australia, following an improved understanding of the significant impact of climate variability and change occurring on interannual to multidecadal timescales. This paper provides evidence of regime shifts in annual maximum rainfall time series (between 1913-2010) using 96 daily rainfall stations and 66 sub-daily rainfall stations across Australia. Furthermore, the effect of these regime shifts on the resulting IFD estimates are explored for three long-term (1913-2010) sub-daily rainfall records (Brisbane, Sydney, and Melbourne) utilizing insights into multidecadal climate variability. It is demonstrated that IFD relationships may under- or over-estimate the design rainfall depending on the length and time period spanned by the rainfall data used to develop the IFD information. It is recommended that regime shifts in annual maximum rainfall be explicitly considered and appropriately treated in the ongoing revisions of the Engineers Australia guide to estimating and utilizing IFD information, Australian Rainfall and Runoff (ARR), and that clear guidance needs to be provided on how to deal with the issue of regime shifts in extreme events (irrespective of whether this is due to natural or anthropogenic climate change). The findings of our study also have important implications for other regions of the world that exhibit considerable hydroclimatic variability and where IFD information is based on relatively short data sets.

    Rates of new HIV-1 diagnoses are increasing in Australia, with evidence of an increasing proportion of non-B HIV-1 subtypes reflecting a growing impact of migration and travel. The present study aims to define HIV-1 subtype diversity patterns and investigate possible HIV-1 transmission networks within Australia. The Australian Molecular Epidemiology Network (AMEN) HIV collaborating sites in Western Australia, South Australia, Victoria, Queensland and western Sydney (New South Wales), provided baseline HIV-1 partial pol sequence, age and gender information for 4,873 patients who had genotypes performed during 2005-2012. HIV-1 phylogenetic analyses utilised MEGA V6, with a stringent classification of transmission pairs or clusters (bootstrap ≥98%, genetic distance ≤1.5% from at least one other sequence in the cluster). HIV-1 subtype B represented 74.5% of the 4,873 sequences (WA 59%, SA 68.4%, w-Syd 73.8%, Vic 75.6%, Qld 82.1%), with similar proportion of transmission pairs and clusters found in the B and non-B cohorts (23% vs 24.5% of sequences, p = 0.3). Significantly more subtype B clusters were comprised of ≥3 sequences compared with non-B clusters (45.0% vs 24.0%, p = 0.021) and significantly more subtype B pairs and clusters were male-only (88% compared to 53% CRF01_AE and 17% subtype C clusters). Factors associated with being in a cluster of any size included; being sequenced in a more recent time period (p3) was associated with being sequenced in a more recent time period (p = 0.05) and being male (p = 0.008). This nationwide HIV-1 study of 4,873 patient sequences highlights the increased diversity of HIV-1 subtypes within the Australian epidemic, as well as differences in transmission networks associated with these HIV-1 subtypes. These findings provide epidemiological insights not readily available using standard surveillance methods and can inform the development of effective public health strategies in the current paradigm of HIV prevention in

  13. Technology meets tradition: The perceived impact of the introduction of information and communication technology on ward rounds in the intensive care unit. (United States)

    Plumb, Jennifer J; Hains, Isla; Parr, Michael J; Milliss, David; Herkes, Robert; Westbrook, Johanna I


    Public policy in many health systems is currently dominated by the quest to find ways to 'do more with less'-to achieve better outcomes at a reduced cost. The success or failure of initiatives in support of this quest are often understood in terms of an adversarial dynamic or struggle between the professional logics of medicine and of management. Here, we use the case of the introduction of information and communication technology (ICT) to a well-established ritual of medical autonomy (the medical ward round) to articulate a more nuanced explanation of how and why new ways of working with technology are accepted and adopted (or not). The study was conducted across four intensive care units (ICUs) in major teaching hospitals in Sydney, Australia. Using interviews, we examined 48 doctors' perceptions of the impact of ICT on ward round practice. We applied the concept of institutional logics to frame our analysis. Interview transcripts were analysed using a hybrid of deductive and inductive thematic analysis. The doctors displayed a complex engagement with the technology that belies simplistic characterisations of medical rejection of managerial encroachment. In fact, they selectively welcomed into the ward round aspects of the technology which reinforced the doctor's place in the healthcare hierarchy and which augmented their role as scientists. At the same time, they guarded against allowing managerial logic embedded in ICT to de-emphasise their embodied subjectivity in relation to the patient as a person rather than as a collection of parameters. ICT can force the disruption of some aspects of existing routines, even where these are long-established rituals. Resistance arose when the new technology did not fit with the 'logic of care'. Incorporation of the logic of care into the design and customisation of clinical information systems is a challenge and potentially counterproductive, because it could attempt to apply a technological fix to what is essentially a

    The Sydney Heart Bank (SHB) is one of the largest human heart tissue banks in existence. Its mission is to provide high-quality human heart tissue for research into the molecular basis of human heart failure by working collaboratively with experts in this field. We argue that, by comparing tissues from failing human hearts with age-matched non-failing healthy donor hearts, the results will be more relevant than research using animal models, particularly if their physiology is very different from humans. Tissue from heart surgery must generally be used soon after collection or it significantly deteriorates. Freezing is an option but it raises concerns that freezing causes substantial damage at the cellular and molecular level. The SHB contains failing samples from heart transplant patients and others who provided informed consent for the use of their tissue for research. All samples are cryopreserved in liquid nitrogen within 40 min of their removal from the patient, and in less than 5-10 min in the case of coronary arteries and left ventricle samples. To date, the SHB has collected tissue from about 450 failing hearts (>15,000 samples) from patients with a wide range of etiologies as well as increasing numbers of cardiomyectomy samples from patients with hypertrophic cardiomyopathy. The Bank also has hearts from over 120 healthy organ donors whose hearts, for a variety of reasons (mainly tissue-type incompatibility with waiting heart transplant recipients), could not be used for transplantation. Donor hearts were collected by the St Vincent's Hospital Heart and Lung transplantation team from local hospitals or within a 4-h jet flight from Sydney. They were flushed with chilled cardioplegic solution and transported to Sydney where they were quickly cryopreserved in small samples. Failing and/or donor samples have been used by more than 60 research teams around the world, and have resulted in more than 100 research papers. The tissues most commonly requested are

  20. Combining a Climatic Niche Model of an Invasive Fungus with Its Host Species Distributions to Identify Risks to Natural Assets: Puccinia psidii Sensu Lato in Australia (United States)

    Kriticos, Darren J.; Morin, Louise; Leriche, Agathe; Anderson, Robert C.; Caley, Peter


    Puccinia psidii sensu lato (s.l.) is an invasive rust fungus threatening a wide range of plant species in the family Myrtaceae. Originating from Central and South America, it has invaded mainland USA and Hawai'i, parts of Asia and Australia. We used CLIMEX to develop a semi-mechanistic global climatic niche model based on new data on the distribution and biology of P. psidii s.l. The model was validated using independent distribution data from recently invaded areas in Australia, China and Japan. We combined this model with distribution data of its potential Myrtaceae host plant species present in Australia to identify areas and ecosystems most at risk. Myrtaceaeous species richness, threatened Myrtaceae and eucalypt plantations within the climatically suitable envelope for P. psidii s.l in Australia were mapped. Globally the model identifies climatically suitable areas for P. psidii s.l. throughout the wet tropics and sub-tropics where moist conditions with moderate temperatures prevail, and also into some cool regions with a mild Mediterranean climate. In Australia, the map of species richness of Myrtaceae within the P. psidii s.l. climatic envelope shows areas where epidemics are hypothetically more likely to be frequent and severe. These hotspots for epidemics are along the eastern coast of New South Wales, including the Sydney Basin, in the Brisbane and Cairns areas in Queensland, and in the coastal region from the south of Bunbury to Esperance in Western Australia. This new climatic niche model for P. psidii s.l. indicates a higher degree of cold tolerance; and hence a potential range that extends into higher altitudes and latitudes than has been indicated previously. The methods demonstrated here provide some insight into the impacts an invasive species might have within its climatically suited range, and can help inform biosecurity policies regarding the management of its spread and protection of valued threatened assets.

    Full Text Available This article on the literary creativity of Slovene rnigrants in Australia after the Second World War, including the most recent publications, discusses only the most artistically accomplished auth­ ors and addresses those works that have received the most enthusiastic reception by the critics and readers alike. Of course, those who are not mentioned are also important to the preservation of Slovene culture and identity among the Slovene migrants in Australia from a documentary, histori­ cal,or ethnological points of view. However, the genresfeatured here include the explicitly literary, the semi-literary fictionalized biography, the memoir and documentary fiction, and the literary journalistic text - all those fields and genres that nowadays straddle the division line between 'high' literature and so-called 'creative fiction'.

  3. Epidemiology of osteoarthritis in Australia. (United States)

    March, Lynette M; Bagga, Hanish


    Arthritis affects around 3 million people in Australia, representing about 15% of the population. Osteoarthritis is the leading cause of pain and disability among the elderly. Osteoarthritis is the third leading cause of life-years lost due to disability. Obesity and joint injury are important potentially modifiable risk factors for the development of osteoarthritis. Obesity is also an important predictor of progression of osteoarthritis. Currently, about 19000 hip and 20000 knee replacements are performed for osteoarthritis in Australia each year. Prevalence of osteoarthritis and the need for total joint replacement surgery are likely to increase because of a combination of increasing risk factors (age, obesity, injury), increasing expectations for improved quality of life, and improved surgical and anaesthetic techniques making surgery possible for more people. Services to provide these cost-effective procedures need to be increased. Primary and secondary prevention programs aimed at reducing obesity, preventing injury and improving rehabilitation and physical activity are urgently required.

  4. Modelling Australia's Retail Mortgage Rate


    Abbas Valadkhani; Sajid Anwar


    There is an ongoing controversy over whether banks’ mortgage rates rise more readily than they fall due to their asymmetric responses to changes in the cash rate. This paper examines the dynamic interplay between the cash rate and the variable mortgage rate using monthly data in the post-1989 era. Unlike previous studies for Australia, our proposed threshold and asymmetric error-correction models account for both the amount and adjustment asymmetries. We found thatrate rises have much larger ...

  5. Protocols for the remediation of lands impacted by former coal mining operations, Sydney coalfield, Nova Scotia, Canada

    Energy Technology Data Exchange (ETDEWEB)

    Forgeron, S. [Conestoga-Rovers and Associates, Sydney, NS (Canada)


    Abandoned underground coal mines can pose health and safety risks to persons working in close proximity to the former mining operations. This paper described protocols used to address potential coal mining hazards at the Sydney coal field in Nova Scotia (NS). The protocols document was developed by a mine workings group consisting of government agencies, consultants, and the owners of the mine site. Hazards at the mine included unstable ground caused by the collapse of abandoned coal mine workings; unsecured abandoned mine openings; potential accidental discharges of untreated mine waters; and the potential release of hazardous mine gases. A 5 remediation protocol process was established to include (1) information gathering, (2) an initial mine site investigation, (3) a mine workings report, (4) a detailed mine site investigation, and (5) a mine openings remediation. The protocols can be used to identify the potential hazards posed during investigations and remediation activities. 26 refs., 1 fig.

  6. What makes a hospital-based psychiatry training program successful? The experience of St Vincent's Hospital, Sydney. (United States)

    Burke, David; Tietze, Tad; Chiem, Lyn; Boulton, Matthew; McGeorge, Peter; Andrews, Gavin


    The purpose of this paper is to describe those features that have contributed to the popularity and success of the psychiatry training program at St Vincent's Hospital, Sydney, and to discuss the factors that potentially weaken the program and how these might be addressed. The strengths of the psychiatry training program at St Vincent's Hospital are the high rate of recruitment of junior medical officers to psychiatry training, the provision of quality in-house teaching, the in-house provision of psychotherapy supervision and exam preparation, the positive influence of the chief psychiatry registrar, having enough trainees to alleviate the tension between training and service delivery, and the availability of a variety of 'extra', high-quality, professional development opportunities.

  7. 'Watch out for these KILLERS!': newspaper coverage of the Sydney funnel web spider and its impact on antivenom research. (United States)

    Cushing, Nancy; Markwell, Kevin


    Based on a content analysis of treatments of the funnel web spider in the Sydney Morning Herald between 1955 and 1985, this paper argues that negative attitudes towards the funnel web were encouraged throughout this period in news stories, commentary, and advertisements and were demonstrated in the reported words and actions of members of the general public. Despite this opprobrium, research into a funnel web antivenom was able to proceed because of the willingness of individuals to collect the spiders and forward them to researchers. Negative attitudes towards the funnel web were able to be directed to a positive action which eventually helped to bring about the development of an antivenom, lessening the real threat posed by the spider.

  8. Deadly occupations: Assessing tuberculosis and accidental mortality among male workers in Sydney and Glace Bay, Nova Scotia, 1909–1917

Factoring in the effects of occupation,age at death, birthplace, community, and marital status, logistic regression results indicate that, among the men who died, occupation is a significant predictor for accidental deaths (relative to all other causes of death but not for tuberculosis-related deaths. Interpretation of these results is grounded in a broader perspective on the nature of living and working conditions in these two single-industry communities.

  9. Karst and agriculture in Australia.

    Directory of Open Access Journals (Sweden)

    Gillieson David


    Full Text Available Much of the development and degradation of karst lands in Australia has occurred in the last two centuries since European settlement. Recent prolonged El Nino events add further climatic uncertainty and place real constraints on sustainable agriculture. The lower southeast of South Australia is perhaps the one area in Australia where karst, and particularly karst hydrology, impinge on the daily lives of the community in that pollution and overexploitation of the aquifer are readily apparent to the local population. Effluent from intensive dairy farms, piggeries and cheese factories enters the karst and has caused concern over pollution of water supplies. Human impacts on the Mole Creek karst of Tasmania have been well documented. The principal recent impacts on the karst arc associated with land clearance for farmland, forest cutting for timber, road building, refuse disposal and associated hydrological change. There is similar evidence of agricultural impacts un karst in central New South Wales, with clear evidence of vegetation clearance and soil stripping on the limestones at Wellington, Orange and Molong.

  10. Medullosalean fusain trunk from the roof rocks of a coal seam: Insight from FTIR and NMR (Pennsylvanian Sydney Coalfield, Canada)

    Reported for the first time from the Sydney Coalfield, Canada, is a fragmentary fusain (R{sub o} = 2.51%) specimen, 41 cm long, of a medullosalean trunk or massive petiole that originated from the roof rocks of the banded bituminous Hub Seam (R{sub o} {proportional_to} 0.65%). Megascopic characteristics of the flat-preserved specimen include an irregular-cracked fusain surface with secretinite-rodlet structures and sclerenchymatous strands some of which still embedded in the shaly matrix, and locally preserved vitrain (R{sub o} 0.69%). Co-occurrence with a compression flora composed virtually of only the seed-fern taxon Macroneuropteris scheuchzeri (Hoffmann) is noted. The goal of this study is to provide a framework for the phytophysicochemical taphonomic history which includes the perspective on vitrinite/fusinite relationship, formation of fusinite, and on the significance the only fusinized identifiable plant-fossil specimen in the Sydney Coalfield. We use state-of-the-art solid-state FTIR, {sup 13}C, {sup 1}H NMR CP/MAS techniques, and standard reflected-light microscopy and SEM methods as investigative tools. Results indicate that the fusinite is characterized by long and narrow xylem fibers, without fungal signals, and cell structures infilled with pyrite and carbonate. FTIR spectra of the fusinite and secretinite are similar particularly in respect to high absorbance of aromatic and low absorbance of aliphatic compounds, and absorbance of Si-O functionalities relating to kaolinite. {sup 13}C NMR experiments with direct carbon excitation quantify the aromatic to aliphatic ratio as being 20 {+-} 3:1. As part of the taphonomic history, the evidence favors a hot, > 400 C, directional surface-fueled flame palaeofire of local extent that charred trunks of growing arborescent seed ferns on only one side, and that these trunks were transported to comprise part of the roof rocks of the Hub Seam.

  11. Tuberculosis notifications in Australia, 2011. (United States)

    Bareja, Christina; Waring, Justin; Stapledon, Richard; Toms, Cindy; Douglas, Paul


    The National Notifiable Diseases Surveillance System received 1,385 tuberculosis (TB) notifications in 2011, representing a rate of 6.2 cases per 100,000 population. While Australia has maintained a rate of 5 to 6 cases per 100,000 for TB since the mid-1980s, there has been a steady increase in incidence over the past decade. In 2011, Australia's overseas-born population continued to represent the majority of TB notifications (88%) with a notification rate of 20.2 per 100,000. The incidence of TB in the Australian-born Indigenous population has fluctuated over the last decade and showed no clear trend; however, in 2011 the notification rate was 4.9 per 100,000, which is a notable decrease from the 7.5 per 100,000 recorded in 2010. The incidence of TB in the Australian-born non-Indigenous population has continued to remain low at 0.9 per 100,000. Australia continued to record only a small number of multi-drug-resistant TB (MDR-TB) cases nationally (n=25), all of which were identified in the overseas-born population. To ensure that Australia can retain its low TB rate and work toward reducing rates further, it is essential that Australia maintains good centralised national TB reporting to monitor trends and identify at-risk populations, and continues to contribute to global TB control initiatives.

    At the third Conference of the Parties to the United Nations Framework Convention for Climate Change (COP3) held in December 1997, the industrialized nations have agreed on development and proliferation of innovative technologies under international cooperation and transfer of environmental technologies to developing countries by expanding and strengthening CTI being the framework to be progressed spontaneously. Under the international strategic research project for global environment, NEDO has been promoting positively the research and development, whose support is urged to be expanded further in the future upon receiving the present agreement. Therefore, NEDO has performed the present survey in order to propose frameworks and measures for strengthening and expanding CTI. From among the policies and measures to be taken by the related countries based on the COP3 protocol, fiscal 1997 has performed review and new establishment of plans involved with execution of the items related to technology development, and surveys on action movements such as review and expansion of the measures, as the first stage. Fiscal 1998 has executed surveys focusing on the network for technology proliferation and transfer to developing countries as the second stage. (NEDO)

  13. Asynchrony of wind and hydropower resources in Australia. (United States)

    Gunturu, Udaya Bhaskar; Hallgren, Willow


    Wind and hydropower together constitute nearly 80% of the renewable capacity in Australia and their resources are collocated. We show that wind and hydro generation capacity factors covary negatively at the interannual time scales. Thus, the technology diversity mitigates the variability of renewable power generation at the interannual scales. The asynchrony of wind and hydropower resources is explained by the differential impact of the two modes of the El Ni˜no Southern Oscillation - canonical and Modoki - on the wind and hydro resources. Also, the Modoki El Ni˜no and the Modoki La Ni˜na phases have greater impact. The seasonal impact patterns corroborate these results. As the proportion of wind power increases in Australia's energy mix, this negative covariation has implications for storage capacity of excess wind generation at short time scales and for generation system adequacy at the longer time scales.

  14. An empirically-derived approach for investigating Health Information Technology: the Elementally Entangled Organisational Communication (EEOC framework

    Directory of Open Access Journals (Sweden)

    Georgiou Andrew


    Full Text Available Abstract Background The purpose of this paper is to illustrate the Elementally Entangled Organisational Communication (EEOC framework by drawing on a set of three case studies which assessed the impact of new Health Information Technology (HIT on a pathology service. The EEOC framework was empirically developed as a tool to tackle organisational communication challenges in the implementation and evaluation of health information systems. Methods The framework was synthesised from multiple research studies undertaken across a major metropolitan hospital pathology service during the period 2005 to 2008. These studies evaluated the impact of new HIT systems in pathology departments (Laboratory Information System and an Emergency Department (Computerised Provider Order Entry located in Sydney, Australia. Results Key dimensions of EEOC are illustrated by the following case studies: 1 the communication infrastructure between the Blood Bank and the ward for the coordination and distribution of blood products; 2 the organisational environment in the Clinical Chemistry and Haematology departments and their attempts to organise, plan and control the processing of laboratory specimens; and 3 the temporal make up of the organisation as revealed in changes to the way the Central Specimen Reception allocated, sequenced and synchronised work tasks. Conclusions The case studies not only highlight the pre-existing communication architecture within the organisation but also the constitutive role communication plays in the way organisations go about addressing their requirements. HIT implementation involves a mutual transformation of the organisation and the technology. This is a vital consideration because of the dangers associated with poor organisational planning and implementation of HIT, and the potential for unintended adverse consequences, workarounds and risks to the quality and safety of patient care. The EEOC framework aims to account for the complex

  15. Travel risk behaviours and uptake of pre-travel health preventions by university students in Australia

    Directory of Open Access Journals (Sweden)

    Heywood Anita E


    Full Text Available Abstract Background Forward planning and preventative measures before travelling can significantly reduce the risk of many vaccine preventable travel-related infectious diseases. Higher education students may be at an increased risk of importing infectious disease as many undertake multiple visits to regions with higher infectious disease endemicity. Little is known about the health behaviours of domestic or international university students, particularly students from low resource countries who travel to high-resource countries for education. This study aimed to assess travel-associated health risks and preventative behaviours in a sample of both domestic and international university students in Australia. Methods In 2010, a 28 item self-administered online survey was distributed to students enrolled at the University of New South Wales, Sydney, Australia. Multiple methods of distributing links to the online survey were utilised. The survey examined the international travel history, travel intentions, infection control behaviours and self-reported vaccination history. Results A total of 1663 respondents completed the online survey, 22.1% were international students and 83.9% were enrolled at an undergraduate level. Half had travelled internationally in the previous 12 months, with 69% of those travelling only once during that time with no difference in travel from Australia between domestic and international students (p = 0.8. Uptake of pre-travel health advice was low overall with 68% of respondents reporting they had not sought any advice from a health professional prior to their last international trip. Domestic students were more likely to report uptake of a range of preventative travel health measures compared to international students, including diarrhoeal medication, insect repellent, food avoidance and condoms (P Conclusions Our study highlights the need to educate students about the risk associated with travel and improve preventative

    "This article is presented in two parts. The first contains a discussion of Australia's migration programme, its different categories and changes in intakes. It also deals with the contribution made by immigration to the size of the labour force.... The second part deals with the effect of immigration on the unemployment rate and concludes that its effect is negligible or, at best, slightly positive.... Against this background the paper discusses factors contributing to the employment and unemployment experience of migrants, for whom English language proficiency and the possession of recognized skills and qualifications are important in determining employability."

  17. Movement of a tritium plume in shallow groundwater at a legacy low-level radioactive waste disposal site in eastern Australia. (United States)

    Hughes, C E; Cendón, D I; Harrison, J J; Hankin, S I; Johansen, M P; Payne, T E; Vine, M; Collins, R N; Hoffmann, E L; Loosz, T


    Between 1960 and 1968 low-level radioactive waste was buried in a series of shallow trenches near the Lucas Heights facility, south of Sydney, Australia. Groundwater monitoring carried out since the mid 1970s indicates that with the exception of tritium, no radioactivity above typical background levels has been detected outside the immediate vicinity of the trenches. The maximum tritium level detected in ground water was 390 kBq/L and the median value was 5400 Bq/L, decay corrected to the time of disposal. Since 1968, a plume of tritiated water has migrated from the disposal trenches and extends at least 100 m from the source area. Tritium in rainfall is negligible, however leachate from an adjacent and fill represents a significant additional tritium source. Study data indicate variation in concentration levels and plume distribution in response to wet and dry climatic periods and have been used to determine pathways for tritium migration through the subsurface.

  18. The Oweniidae (Annelida; Polychaeta) from Lizard Island (Great Barrier Reef, Australia) with the description of two new species of Owenia Delle Chiaje, 1844. (United States)

    Parapar, Julio; Moreira, Juan


    Study of the Oweniidae specimens (Annelida; Polychaeta) from Lizard Island (Great Barrier Reef, Australia) stored at the Australian Museum, Sydney and newly collected in August 2013 revealed the presence of three species, namely Galathowenia quelis Capa et al., 2012 and two new species belonging to the genus Owenia Delle Chiaje, 1844. Owenia dichotoma n. sp. is characterised by a very short branchial crown of about 1/3 of thoracic length which bears short, dichotomously-branched tentacles provided with the major division close to the base of the crown. Owenia picta n. sp. is characterised by a long branchial crown of about 4/5 of thoracic length provided with no major divisions, ventral pigmentation on thorax and the presence of deep ventro-lateral groove on the first thoracic chaetiger. A key of Owenia species hitherto described or reported in South East Asia and Australasia regions is provided based on characters of the branchial crown.

  19. Evolution of newspaper coverage of water issues in Australia during 1843-2011. (United States)

    Wei, Jing; Wei, Yongping; Western, Andrew; Skinner, Dominic; Lyle, Clive


    News accounts both reflect and influence public opinion through their noted 'agenda-setting' capability. We examined newspaper articles in Australia's The Sydney Morning Herald from 1843 to 2011 to observe the evolution of media coverage on water issues related to water resources management. The results showed that water supply-related articles have dominated the reporting of water issues since 1843. This emphasis is reflected in the institutions involved and their related policy/management initiatives, as well as the themes of the articles. Extreme events such as flooding and drought have punctuated the historical record of reports on water issues. An economic development-driven tone was overwhelmingly predominant in newspaper articles (85 % of the total); however, there has been a marked decline in the importance of development-driven tone relative to environmental-sustainability oriented tone of articles since 1994. People from academia and NGOs were rarely quoted. Inclusion of wider range stakeholders should be considered as a strategic break-through and natural events should be considered as an "opportunity" to change public opinion on water issues for environmental sustainability.

  20. Avian Assemblages at Bird Baths: A Comparison of Urban and Rural Bird Baths in Australia. (United States)

    Cleary, Gráinne P; Parsons, Holly; Davis, Adrian; Coleman, Bill R; Jones, Darryl N; Miller, Kelly K; Weston, Michael A


    Private gardens provide habitat and resources for many birds living in human-dominated landscapes. While wild bird feeding is recognised as one of the most popular forms of human-wildlife interaction, almost nothing is known about the use of bird baths. This citizen science initiative explores avian assemblages at bird baths in private gardens in south-eastern Australia and how this differs with respect to levels of urbanisation and bioregion. Overall, 992 citizen scientists collected data over two, four-week survey periods during winter 2014 and summer 2015 (43% participated in both years). Avian assemblages at urban and rural bird baths differed between bioregions with aggressive nectar-eating species influenced the avian assemblages visiting urban bird baths in South Eastern Queensland, NSW North Coast and Sydney Basin while introduced birds contributed to differences in South Western Slopes, Southern Volcanic Plains and Victorian Midlands. Small honeyeaters and other small native birds occurred less often at urban bird baths compared to rural bird baths. Our results suggest that differences between urban versus rural areas, as well as bioregion, significantly influence the composition of avian assemblages visiting bird baths in private gardens. We also demonstrate that citizen science monitoring of fixed survey sites such as bird baths is a useful tool in understanding large-scale patterns in avian assemblages which requires a vast amount of data to be collected across broad areas.

  1. A new pupillarial scale insect (Hemiptera: Coccoidea: Eriococcidae) from Angophora in coastal New South Wales, Australia. (United States)

    Gullan, Penny J; Williams, Douglas J


    A new scale insect, Aolacoccus angophorae gen. nov. and sp. nov. (Eriococcidae), is described from the bark of Angophora (Myrtaceae) growing in the Sydney area of New South Wales, Australia. These insects do not produce honeydew, are not ant-tended and probably feed on cortical parenchyma. The adult female is pupillarial as it is retained within the cuticle of the penultimate (second) instar. The crawlers (mobile first-instar nymphs) emerge via a flap or operculum at the posterior end of the abdomen of the second-instar exuviae. The adult and second-instar females, second-instar male and first-instar nymph, as well as salient features of the apterous adult male, are described and illustrated. The adult female of this new taxon has some morphological similarities to females of the non-pupillarial palm scale Phoenicococcus marlatti Cockerell (Phoenicococcidae), the pupillarial palm scales (Halimococcidae) and some pupillarial genera of armoured scales (Diaspididae), but is related to other Australian Myrtaceae-feeding eriococcids.

  2. Investigating nutrient profiling and Health Star Ratings on core dairy products in Australia. (United States)

    Wellard, Lyndal; Hughes, Clare; Watson, Wendy L


    To determine whether the ratings from the Australian front-of-pack labelling scheme, Health Star Rating (HSR), and the ability to carry health claims using the Nutrient Profiling Scoring Criterion (NPSC) for core dairy products promote foods consistent with the Australian Dietary Guidelines. The Australian nutrient profiling model used for assessing eligibility for health claims was compared with the nutrient profiling model underpinning the HSR system to determine their agreement when assessing dairy products. Agreement between the extent to which products met nutrient profiling criteria and scored three stars or over using the HSR calculator was determined using Cohen's kappa tests. The four largest supermarket chains in Sydney, Australia. All available products in the milk, hard cheese, soft cheese and yoghurt categories (n 1363) were surveyed in March-May 2014. Nutrition composition and ingredients lists were recorded for each product. There was 'good' agreement between NPSC and HSR overall (κ=0·78; 95 % CI 0·75, 0·81; Psystems appeared be consistent with the Australian Dietary Guidelines for dairy products, with lower-fat products rating higher.

  3. CO 2 degassing and trapping during hydrothermal cycles related to Gondwana rifting in eastern Australia (United States)

    Uysal, I. Tonguç; Golding, Suzanne D.; Bolhar, Robert; Zhao, Jian-xin; Feng, Yue-xing; Baublys, Kim A.; Greig, Alan


    Intensive carbonate and clay mineral authigenesis took place throughout the Late Permian Bowen-Gunnedah-Sydney basin system in eastern Australia. We conducted isotopic and trace element analyses of carbonate and clay minerals from clastic sedimentary rocks of the Gunnedah Basin and the Denison Trough in the Bowen Basin. Rb-Sr isochron age data of the illitic clays are consistent with episodic hydrothermal fluid flow events that occurred in association with Gondwana rifting accompanied by alkaline magmatism at ˜85 Ma and ˜95 Ma. Stable isotope data of carbonate and clay minerals from the Gunnedah Basin are indicative of meteoric waters from a high-latitude environment as the main fluid source, whereas trace element, Sr and Nd isotope data highlight mixing of meteoric fluids with magmatic and/or crustal components, with a possible input from marine carbonates for some samples. Trace metals, oxygen and strontium isotopes of dawsonites from the Denison Trough are interpreted to have been mobilised by fluids that interacted with evolved clastic sedimentary and marine carbonate end members. According to the carbon isotope data, CO 2 for calcite and ankerite precipitation was sourced mainly from thermal degradation of organic matter and magmatism, whereas the CO 2 used for dawsonite formation is inferred to have been derived from magmatic and marine sources. In the low permeability environments (particularly in coal seams), the increasing accumulation and oversaturation of CO 2 particularly promote the precipitation of dawsonite.

  4. Atmospheric transport modelling of time resolved 133Xe emissions from the isotope production facility ANSTO, Australia. (United States)

    Schöppner, M; Plastino, W; Hermanspahn, N; Hoffmann, E; Kalinowski, M; Orr, B; Tinker, R


    The verification of the Comprehensive Nuclear-Test Ban Treaty (CTBT) relies amongst other things on the continuous and worldwide monitoring of radioxenon. The characterization of the existing and legitimate background, which is produced mainly by nuclear power plants and isotope production facilities, is of high interest to improve the capabilities of the monitoring network. However, the emissions from legitimate sources can usually only be estimated. For this paper historic source terms of (133)Xe emissions from the isotope production facility at ANSTO, Sydney, Australia, have been made available in a daily resolution. Based on these high resolution data, different source term sets with weekly, monthly and yearly time resolution have been compiled. These different sets are then applied together with atmospheric transport modelling (ATM) to predict the concentration time series at two radioxenon monitoring stations. The results are compared with each other in order to examine the improvement of the prediction capability depending on the used time resolution of the most dominant source term in the region.

  5. Single Tablet Regimen Usage and Efficacy in the Treatment of HIV Infection in Australia

    Directory of Open Access Journals (Sweden)

    B. Armstrong


    Full Text Available Single tablet regimens (STRs for HIV infection improve patient satisfaction, quality of life, medication adherence, and virological suppression compared to multitablet regimens (MTRs. This is the first study assessing STR uptake and durability in Australia. This retrospective audit of all patients receiving an STR (n=299 at a large Sydney HIV clinic (January 2012–December 2013 assessed patient demographics, treatment prior to STR, HIV RNA load and CD4 during MTR and STR dosing, and reasons for STR switch. 206 patients switched from previous antiretroviral treatment to an STR, of which 88% switched from an MTR. Reasons for switching included desire to simplify treatment (57%, reduced side effects or toxicity (18%, and cost-saving for the patient. There was no switching for virological failure. Compared to when on an MTR, patients switching to an STR had significantly lower HIV RNA counts (p<0.001 and significantly higher CD4 counts (p<0.001. The discontinuation rate from STR was very low and all patients who switched to an STR maintained virological suppression throughout the study duration, although the study is limited by the absence of a control group.

  6. Genetic Connectivity among Populations of an Endangered Snake Species from Southeastern Australia (Hoplocephalus bungaroides, Elapidae). (United States)

    Dubey, Sylvain; Sumner, Joanna; Pike, David A; Keogh, J Scott; Webb, Jonathan K; Shine, Richard


    For endangered species that persist as apparently isolated populations within a previously more extensive range, the degree of genetic exchange between those populations is critical to conservation and management. A lack of gene flow can exacerbate impacts of threatening processes and delay or prevent colonization of sites after local extirpation. The broad-headed snake, Hoplocephalus bungaroides, is a small venomous species restricted to a handful of disjunct reserves near Sydney, Australia. Mark-recapture studies have indicated low vagility for this ambush predator, suggesting that gene flow also may be low. However, our analyses of 11 microsatellite loci from 163 snakes collected in Morton National Park, from six sites within a 10-km diameter, suggest relatively high rates of gene flow among sites. Most populations exchange genes with each other, with one large population serving as a source area and smaller populations apparently acting as sinks. About half of the juvenile snakes, for which we could reliably infer parentage, were collected from populations other than those in which we collected their putative parents. As expected from the snakes' reliance on rocky outcrops during cooler months of the year, most gene flow appears to be along sandstone plateaux rather than across the densely forested valleys that separate plateaux. The unexpectedly high rates of gene flow on a landscape scale are encouraging for future conservation of this endangered taxon. For example, wildlife managers could conserve broad-headed snakes by restoring habitats near extant source populations in areas predicted to be least affected by future climate change.

  8. Statistical Testing of Dynamically Downscaled Rainfall Data for the East Coast of Australia (United States)

    Parana Manage, Nadeeka; Lockart, Natalie; Willgoose, Garry; Kuczera, George


    This study performs a validation of statistical properties of downscaled climate data, concentrating on the rainfall which is required for hydrology predictions used in reservoir simulations. The data sets used in this study have been produced by the NARCliM (NSW/ACT Regional Climate Modelling) project which provides a dynamically downscaled climate dataset for South-East Australia at 10km resolution. NARCliM has used three configurations of the Weather Research Forecasting Regional Climate Model and four different GCMs (MIROC-medres 3.2, ECHAM5, CCCMA 3.1 and CSIRO mk3.0) from CMIP3 to perform twelve ensembles of simulations for current and future climates. Additionally to the GCM-driven simulations, three control run simulations driven by the NCEP/NCAR reanalysis for the entire period of 1950-2009 has also been performed by the project. The validation has been performed in the Upper Hunter region of Australia which is a semi-arid to arid region 200 kilometres North-West of Sydney. The analysis used the time series of downscaled rainfall data and ground based measurements for selected Bureau of Meteorology rainfall stations within the study area. The initial testing of the gridded rainfall was focused on the autoregressive characteristics of time series because the reservoir performance depends on long-term average runoffs. A correlation analysis was performed for fortnightly, monthly and annual averaged time resolutions showing a good statistical match between reanalysis and ground truth. The spatial variation of the statistics of gridded rainfall series were calculated and plotted at the catchment scale. The spatial correlation analysis shows a poor agreement between NARCliM data and ground truth at each time resolution. However, the spatial variability plots show a strong link between the statistics and orography at the catchment scale.

  9. Storage mite contamination of commercial dry dog food in south-eastern Australia. (United States)

    Hibberson, C E; Vogelnest, L J


    To evaluate contamination of unopened and opened stored sources of commercial dry dog food by viable storage mites. Prospective laboratory and field study. Samples were collected from nine brands of previously unopened bags (new bags) of dry food and 20 field sources of stored dry food in homes in Sydney and Canberra, Australia. All samples were initially examined for the presence of mites using a stereo-binocular microscope and then placed in separate filter-paper-sealed containers. Field samples were incubated at an average temperature of 29°C and 78% relative humidity (RH) for 5 weeks and then at average 26°C/83% RH for 8 weeks. Paired new-bag samples were stored under room conditions (average 23°C/47% RH) and controlled incubator conditions (average 26°C/80% RH) for 6 weeks. All samples were thoroughly examined for mites, mite eggs and visible mould once weekly using a stereo-binocular microscope. Storage mites were not visualised in any of the field samples or in new-bag samples stored at room temperature. Storage mites, identified as Tyrophagus putrescentiae, were visualised in increasing numbers in seven of nine new-bag samples after incubation, with first mites and then eggs evident after 3 weeks of incubation. We confirmed the presence of viable storage mites in a range of previously unopened commercial dry dog foods in Australia and confirmed the possibility of heavy storage mite contamination for dry food stored under conditions of moderate temperature and high humidity. These findings have relevance to storage mite and/or dust mite sensitivity in canine atopic dermatitis. © 2014 Australian Veterinary Association.

  10. The medical officer's journal: HMAS Sydney 1913-1922. An Australian Naval record of surgery and anaesthesia at the time of the outbreak of World War I. (United States)

    McDonald, J M; Todd, E M


    The Medical Officer's Journal of HMAS Sydney was a record kept by the ship's Surgeon, Leonard Darby, of the conditions on the ship and the health, diseases, injuries and treatment of the sailor's under his care. Records of anaesthesia and surgery indicate chloroform was mostly administered as was ether occasionally. There was some use of intravenous and subcutaneous fluids for resuscitation. The journal also provides an eyewitness account of the Sydney-Emden battle on 9 November 1914 which occurred off the Cocos Keeling Islands and was a famous first victory for the young Australian Navy, making headlines around the world. The treatment of the many injured, mostly Germans, is described; with the two Australian surgeons and the surviving German surgeon working together.

  11. Do smoke-free environment policies reduce smoking on hospital grounds? Evaluation of a smoke-free health service policy at two Sydney hospitals. (United States)

    Poder, Natasha; Carroll, Therese; Wallace, Cate; Hua, Myna


    To evaluate the compliance of hospital staff, inpatients and visitors with Sydney South West Area Health Service's Smoke-free Environment Policy. Six sites were observed at two Sydney hospitals 2 weeks before implementation of the policy and at 2 weeks, 6 months, 12 months, 18 months and 2 years after implementation. There was an overall significant 36% (P≤0.05) reduction in observed smoking incidents on hospital grounds 2 years after implementation. Two years after implementation, observed smoking incidents reduced by 44% (P≤0.05) in staff, 37% (P≤0.05) in visitors and remained unchanged among inpatients. The Smoke-free Environment Policy was effective in reducing visitors and staff observed smoking on hospital grounds, but had little effect on inpatients' smoking. Identifying strategies to effectively manage nicotine addiction and promote cessation amongst hospital inpatients remains a key priority.

  17. Application of positive matrix factorization, multi-linear engine and back trajectory techniques to the quantification of coal-fired power station pollution in metropolitan Sydney (United States)

    Cohen, David D.; Crawford, Jagoda; Stelcer, Eduard; Atanacio, Armand J.


    Over 900 fine particle Teflon filters were collected within the Sydney Basin between 1 January 2001 and 31 December 2011 and analyzed using simultaneous PIXE, PIGE, RBS and PESA techniques to determine 21 different elements between hydrogen and lead. These elements were used in positive matrix factorization (PMF) and multi-linear engine (ME) techniques together with HYSPLIT wind back trajectory techniques to quantitatively determine source fingerprints and their contributions from coal-fired power stations. The power stations were many kilometers outside the greater Sydney metropolitan area but still had a significant impact on the fine particle mass loadings measured at the sampling site within this metropolitan area. The PM2.5 eleven year average mass at the sampling site was 6.48 μg m-3. The corresponding ammonium sulfate estimate was 1.65 μg m-3 or 26% of the PM2.5 mass. By applying back trajectory data and (ME) analysis methods, two power related fingerprints, secondary sulfate (2ndrySPower) and aged industrial sulfur (IndSagedPower) were determined. These two power related fingerprints were responsible for between 14 and 18% of the total PM2.5 mass and 34-47% of the total sulfate measured at the sampling site. That is on average somewhere between a third and a half of all the sulfate measured in the greater Sydney region could be attributed to coal-fired power station emissions.

  19. Pharmaceuticals in Australia: developments in regulation and governance. (United States)

    Lofgren, Hans; Boer, Rebecca de


    The pharmaceutical domain represents a type of internationalised policy network theorised in recent writings on neo-liberalism, neo-corporatism and governance. This article presents an analysis of developments in prescription drug regulation in Australia. A relatively stable, state-managed pattern of interaction has been superseded by less closed exchange, and the government itself has fragmented into agencies pursuing different objectives. Developments in the three core regulatory areas are described: safety and efficacy controls, social policy (access and equity), and state support for industry (economic) development. Consensus-building occurs within the context of the National Medicines Policy. The pharmaceutical industry, represented by Medicines Australia, has a stake in all aspects of pharmaceutical policy and regulation, and draws upon unique resources (expertise and lobbying capacity). The context for the developments described is Australia's abandonment of a protectionist version of the Keynesian welfare national state in favour of the model of the competition state, which is oriented towards support for the growth of high technology industries such as pharmaceuticals, premised on partnerships with business.

  20. Non–stationarity in annual maxima rainfall across Australia – implications for Intensity–Frequency–Duration (IFD relationships

    Directory of Open Access Journals (Sweden)

    D. C. Verdon-Kidd


    Full Text Available Rainfall Intensity–Frequency–Duration (IFD relationships are commonly required for the design and planning of water supply and management systems around the world. Currently IFD information is based on the "stationary climate assumption" – that weather at any point in time will vary randomly and that the underlying climate statistics (including both averages and extremes will remain constant irrespective of the period of record. However, the validity of this assumption has been questioned over the last 15 years, particularly in Australia, following an improved understanding of the significant impact of climate variability and change occurring on interannual to multidecadal timescales. This paper provides evidence of non-stationarity in annual maxima rainfall timeseries using 96 daily rainfall stations and 66 sub-daily rainfall stations across Australia. Further, the effect of non-stationarity on the resulting IFD estimates are explored for three long-term sub-daily rainfall records (Brisbane, Sydney and Melbourne utilising insights into multidecadal climate variability. It is demonstrated that IFD relationships may under- or over-estimate the design rainfall depending on the length and time period spanned by the rainfall data used to develop the IFD information. It is recommended that non-stationarity in annual maxima rainfall be explicitly considered and appropriately treated in the ongoing revisions of Engineers Australia's guide to estimating and utilising IFD information, "Australian Rainfall and Runoff", and that clear guidance needs to be provided on how to deal with the issue of non-stationarity of extreme events (irrespective of whether that non-stationarity is due to natural or anthropogenic climate change. The findings of our study also have important implications for other regions of the world that exhibit considerable hydroclimatic variability and where IFD information is based on relatively short data sets.

  1. Innovative management techniques to deal with mine water issues in the Sydney coal field, Nova Scotia, Canada

    Energy Technology Data Exchange (ETDEWEB)

    Shea, J. [Enterprise Cape Breton Corp., Sydney, NS (Canada)


    There are currently 20 mine pools that have flooded to an equilibrium point and are discharging water at the Sydney Coalfield in Nova Scotia (NS). This paper discussed a new mine water technique that is being used at 3 of the mine's mine pools. An emergency active treatment plant was constructed at one of the mine shafts to prevent uncontrolled discharges. A drilling program was also conducted in the inflooded zones of the mine to test the quality of the rising mine water. Pump tests were conducted to allow for the discharge of better quality mine water into a receiving stream without treatment. An automated and remote-controlled pumping system was installed. A passive treatment system consisting of aeration cascades and a 1.2 hectare settling pond and a 1.1 hectare reed bed wetland was constructed. The mine water flow through the pond was designed using a simple piston flow theory that provided a 50 hour retention time for the mine water. Floating pond curtains were also installed. Boreholes were drilled to combine mine waters from other pools into the passive treatment plant. It is expected that mine water issues at the site will be resolved within the next 5 years. 3 refs., 4 figs.

  2. Comparison of Bayesian and frequentist approaches in modelling risk of preterm birth near the Sydney Tar Ponds, Nova Scotia, Canada

    Directory of Open Access Journals (Sweden)

    Canty Angelo


    Full Text Available Abstract Background This study compares the Bayesian and frequentist (non-Bayesian approaches in the modelling of the association between the risk of preterm birth and maternal proximity to hazardous waste and pollution from the Sydney Tar Pond site in Nova Scotia, Canada. Methods The data includes 1604 observed cases of preterm birth out of a total population of 17559 at risk of preterm birth from 144 enumeration districts in the Cape Breton Regional Municipality. Other covariates include the distance from the Tar Pond; the rate of unemployment to population; the proportion of persons who are separated, divorced or widowed; the proportion of persons who have no high school diploma; the proportion of persons living alone; the proportion of single parent families and average income. Bayesian hierarchical Poisson regression, quasi-likelihood Poisson regression and weighted linear regression models were fitted to the data. Results The results of the analyses were compared together with their limitations. Conclusion The results of the weighted linear regression and the quasi-likelihood Poisson regression agrees with the result from the Bayesian hierarchical modelling which incorporates the spatial effects.

  3. Combined exposure to pyrene and fluoranthene and their molecular effects on the Sydney rock oyster, Saccostrea glomerata. (United States)

    Ertl, Nicole G; O'Connor, Wayne A; Brooks, Peter; Keats, Michael; Elizur, Abigail


    Polycyclic aromatic hydrocarbons (PAHs) are ubiquitously detected in the water column, associated with particulate matter or in the tissue of marine organisms such as molluscs. PAH exposure and their resultant bioaccumulation in molluscs can cause a range of serious physiological effects in the affected animals. To examine the molecular response of these xenobiotics in bivalves, Sydney rock oysters (Saccostrea glomerata) were exposed to pyrene and fluoranthene for seven days. Chemical analysis of the soft-tissue of PAH stressed S. glomerata confirmed that pyrene and fluoranthene could be bioaccumulated by these oysters. RNA-Seq analysis of PAH-exposed S. glomerata showed a total of 765 transcripts differentially expressed between control and PAH-stressed oysters. Closer examination of the transcripts revealed a range genes encoding enzymes involved in PAH detoxification (e.g. cytochrome P450), innate immune responses (e.g. pathogen recognition, phagocytosis) and protein synthesis. Overall, pyrene and fluoranthene exposure appears to have resulted in a suppression of pathogen recognition and some protein synthesis processes, whereas transcripts of genes encoding proteins involved in clearance of cell debris and some transcripts of genes involved in PAH detoxification were induced in response to the stressors. Pyrene and fluoranthene exposure thus invoked a complex molecular response in S. glomerata, with results suggesting that oysters focus on removing the stressors from their system and dealing with the downstream effects of PAH exposure, potentially at the exclusion of other, less immediate concerns (e.g. protection from infection).

    Davis, J; Seneta, E B; Tango, W J; Booth, A J; O'Byrne, J W; Thorvaldson, E D; Ausseloos, M; Aerts, C; Uytterhoeven, K


    The bright southern binary star beta Centauri (HR 5267) has been observed with the Sydney University Stellar Interferometer (SUSI) and spectroscopically with the ESO CAT and Swiss Euler telescopes at La Silla. The interferometric observations have confirmed the binary nature of the primary component and have enabled the determination of the orbital parameters of the system. At the observing wavelength of 442 nm the two components of the binary system have a magnitude difference of 0.15. The combination of interferometric and spectroscopic data gives the following results: orbital period 357 days, semi-major axis 25.30 mas, inclination 67.4 degrees, eccentricity 0.821, distance 102.3 pc, primary and secondary masses M1 = M2 = 9.1 solar masses and absolute visual magnitudes of the primary and secondary M1V = -3.85 and M2V = -3.70. The high accuracy of the results offers a fruitful starting point for future asteroseismic modelling of the pulsating binary components.

The Diabetes MILES (Management...... and Impact for Long-term Empowerment and Success) Youth-Australia Study is the first large-scale, national survey of the impact of diabetes on the psychosocial outcomes of Australian adolescents with type 1 diabetes and their parents. METHODS/DESIGN: The survey was web-based to enable a large-scale, national...

  6. Royal Commissions into Policing: Australia

    Directory of Open Access Journals (Sweden)

    Alan Beckley


    Full Text Available Royal Commissions and Inquiries have investigated every police force in Australia in relation to their integrity, accountability and effectiveness—a factor of major importance to every citizen in maintaining their freedom, safety and security. The crucial question this paper poses is whether such tribunals are effective or otherwise in terms of the benefits and outcomes accrued from their findings. The paper is in the form of a critical discussion which investigates and analyses the Inquiries using the method of desk research of official documents over the last 50 years from which it identifies common findings and recommendations contained in the official discourse. The research concludes that lessons have not been learned in relation to policing operations, accountability and integrity in a number of cases and highlights a variety of adverse issues that persist into current policing practice.

  8. A solar fuels roadmap for Australia - study outcomes (United States)

    Hinkley, James T.; McNaughton, Robbie K.; Hayward, Jennifer A.; Lovegrove, Keith


    This paper summarises the key findings and recommendations of a 3.5 year study into the research, development and demonstration priorities to establish a solar fuels industry in Australia. While Australia has one of the best solar resources in the world, it also has an abundance of conventional fuels such as coal and natural gas. The country is heavily dependent on fossil fuels for its primary energy supply and international trade, and is seeking pathways to reduce emissions intensity. While renewable electricity will be able to displace fossil fuels in the electricity sector, this only addresses about 16% of energy consumption by end use. Concentrating solar fuels (CSF) are produced either in full or in part from concentrated solar energy, and can provide either complete or partial reduction of the CO2 emissions associated with energy consumption. Our study reviewed the various potential solar thermal technology pathways and feedstocks available to produce a range of CSF products such as hydrogen, ammonia, methanol and synthetic gasoline or diesel. We conducted what we believe to be the broadest and most sophisticated evaluation of the many options to identify those that are most prospective, including an evaluation of the expected final fuel costs. The study identified the following opportunities for CSF: • Australia: substitution of imported liquid fuels (gasoline and diesel) with synthetic CSF options would provide fuel security through the utilization of domestic resources. Ammonia is also a potentially attractive CSF product as it is produced in large quantities for fertilisers and explosives. • Export markets: Australia has significant trading relationships with many Asian countries in the energy domain, and CSF fuels could provide a long term future to enable such relationships to continue - or grow - in a carbon constrained world. Japan in particular is considering how to transition to a hydrogen economy, and could be a customer for CSF hydrogen or

  9. Iron oxide minerals in dust of the Red Dawn event in eastern Australia, September 2009 (United States)

    Reynolds, Richard L.; Cattle, Stephen R.; Moskowitz, Bruce M.; Goldstein, Harland L.; Yauk, Kimberly; Flagg, Cody B.; Berquó, Thelma S.; Kokaly, Raymond F.; Morman, Suzette; Breit, George N.


    Iron oxide minerals typically compose only a few weight percent of bulk atmospheric dust but are important for potential roles in forcing climate, affecting cloud properties, influencing rates of snow and ice melt, and fertilizing marine phytoplankton. Dust samples collected from locations across eastern Australia (Lake Cowal, Orange, Hornsby, and Sydney) following the spectacular "Red Dawn" dust storm on 23 September 2009 enabled study of the dust iron oxide assemblage using a combination of magnetic measurements, Mössbauer spectroscopy, reflectance spectroscopy, and scanning electron microscopy. Red Dawn was the worst dust storm to have hit the city of Sydney in more than 60 years, and it also deposited dust into the Tasman Sea and onto snow cover in New Zealand. Magnetization measurements from 20 to 400 K reveal that hematite, goethite, and trace amounts of magnetite are present in all samples. Magnetite concentrations (as much as 0.29 wt%) were much higher in eastern, urban sites than in western, agricultural sites in central New South Wales (0.01 wt%), strongly suggesting addition of magnetite from local urban sources. Variable temperature Mössbauer spectroscopy (300 and 4.2 K) indicates that goethite and hematite compose approximately 25-45% of the Fe-bearing phases in samples from the inland sites of Orange and Lake Cowal. Hematite was observed at both temperatures but goethite only at 4.2 K, thereby revealing the presence of nanogoethite (less than about 20 nm). Similarly, hematite particulate matter is very small (some of it d < 100 nm) on the basis of magnetic results and Mössbauer spectra. The degree to which ferric oxide in these samples might absorb solar radiation is estimated by comparing reflectance values with a magnetic parameter (hard isothermal remanent magnetization, HIRM) for ferric oxide abundance. Average visible reflectance and HIRM are correlated as a group (r2 = 0.24), indicating that Red Dawn ferric oxides have capacity to absorb

  10. Australia's TERN: Advancing Ecosystem Data Management in Australia (United States)

    Phinn, S. R.; Christensen, R.; Guru, S.


    Globally, there is a consistent movement towards more open, collaborative and transparent science, where the publication and citation of data is considered standard practice. Australia's Terrestrial Ecosystem Research Network (TERN) is a national research infrastructure investment designed to support the ecosystem science community through all stages of the data lifecycle. TERN has developed and implemented a comprehensive network of ';hard' and ';soft' infrastructure that enables Australia's ecosystem scientists to collect, publish, store, share, discover and re-use data in ways not previously possible. The aim of this poster is to demonstrate how TERN has successfully delivered infrastructure that is enabling a significant cultural and practical shift in Australia's ecosystem science community towards consistent approaches for data collection, meta-data, data licensing, and data publishing. TERN enables multiple disciplines, within the ecosystem sciences to more effectively and efficiently collect, store and publish their data. A critical part of TERN's approach has been to build on existing data collection activities, networks and skilled people to enable further coordination and collaboration to build each data collection facility and coordinate data publishing. Data collection in TERN is through discipline based facilities, covering long term collection of: (1) systematic plot based measurements of vegetation structure, composition and faunal biodiversity; (2) instrumented towers making systematic measurements of solar, water and gas fluxes; and (3) satellite and airborne maps of biophysical properties of vegetation, soils and the atmosphere. Several other facilities collect and integrate environmental data to produce national products for fauna and vegetation surveys, soils and coastal data, as well as integrated or synthesised products for modelling applications. Data management, publishing and sharing in TERN are implemented through a tailored data

  18. Mesozoic/Cenozoic tectonic events around Australia (United States)

    Müller, R. Dietmar; Gaina, Carmen; Tikku, Anahita; Mihut, Dona; Cande, Steven C.; Stock, Joann M.

    We use an absolute and relative plate motion model for the plates around Australia to identify major plate tectonic events, evaluate their causes, and investigate their effects on anomalous intraplate subsidence or uplift and on the history of oceanic crustal accretion. An event at ˜136 Ma is marked by the onset of sea floor spreading between Greater India and Australia. At about this time long-lived subduction east of Australia ceased, probably due to subduction of the Phoenix-Pacific spreading ridge, changing this plate boundary to a transform margin. Between 130 and 80 Ma, Australia and East Antarctica moved eastward in the Atlantic-Indian mantle hotspot reference frame. This can be plausibly linked to ridge push from the NW-SE oriented spreading center NW of Australia and to the inferred geometry and continued subduction of the Phoenix plate beneath the West Antarctic margin. A drastic change in spreading direction between the Indian and Australian plates from NE-SW to N-S occurred at about 99 Ma, possibly caused by a change in absolute motion of the Pacific Plate. Chron 27 (˜61 Ma) marks the onset of relative motion between East and West Antarctica, and a change in the relative motion between Australia and Antarctica. It may be linked to the subduction of a segment of the Neo-Tethyan Ridge. Both events caused anomalous subsidence on the Northwest Shelf of Australia. The almost stationary position of Australia w.r.t. the mantle from ˜80 Ma to ˜40 Ma may reflect the progressive subduction of the Pacific-Phoenix ridge to the east of New Zealand preceding 80 Ma, resulting in a diminished trench suction force east of Australia. Preliminary reconstructions to close the Pacific-Australian plate circuit based on recently collected geophysical data indicate that a tectonic event at 43 Ma may mark the onset of renewed subduction east of Australia. At the same time spreading in the Wharton Basin between India and Australia ceased, and tectonic reactivation is

  19. The potential for LiDAR technology to map fire fuel hazard over large areas of Australian forest. (United States)

    Price, Owen F; Gordon, Christopher E


    Fuel load is a primary determinant of fire spread in Australian forests. In east Australian forests, litter and canopy fuel loads and hence fire hazard are thought to be highest at and beyond steady-state fuel loads 15-20 years post-fire. Current methods used to predict fuel loads often rely on course-scale vegetation maps and simple time-since-fire relationships which mask fine-scale processes influencing fuel loads. Here we use Light Detecting and Remote Sensing technology (LiDAR) and field surveys to quantify post-fire mid-story and crown canopy fuel accumulation and fire hazard in Dry Sclerophyll Forests of the Sydney Basin (Australia) at fine spatial-scales (20 × 20 m cell resolution). Fuel cover was quantified in three strata important for crown fire propagation (0.5-4 m, 4-15 m, >15 m) over a 144 km(2) area subject to varying fire fuel ages. Our results show that 1) LiDAR provided a precise measurement of fuel cover in each strata and a less precise but still useful predictor of surface fuels, 2) cover varied greatly within a mapped vegetation class of the same fuel age, particularly for elevated fuel, 3) time-since-fire was a poor predictor of fuel cover and crown fire hazard because fuel loads important for crown fire propagation were variable over a range of fire fuel ages between 2 and 38 years post-fire, and 4) fuel loads and fire hazard can be high in the years immediately following fire. Our results show the benefits of spatially and temporally specific in situ fuel sampling methods such as LiDAR, and are widely applicable for fire management actions which aim to decrease human and environmental losses due to wildfire.

  20. Population policies in Southeast Asia and Australia: the international relevance of domestic affairs. (United States)

    Jones, G W


    There are 2 underlying themes to this paper: national perceptions of population circumstances at home and abroad are the crucial determinants of population policies adopted, and the differences in perceptions help explain why national reactions differ to circumtances which appear similar; and population policy, though an internal matter, has international repercussions and thus can become a sensitive issue in international relations. Until recently, ASEAN countries were united with Vietnam on at least 1 issue: attitudes toward the growth and changing distribution of their populations. The objectives were slower growth through lowered fertility, resistance to immigration from abroad except in very special circumstances, resettlement of population to undeveloped areas with potential for agriculture, and slowing the growth of big cities. The Australian situation differed. As a high income nation populated primarily through immigration and set in a region of far more populous and densely settled nations, Australia's policy favored population growth and used an immigration program as a way to realize this end. Yet, even so, population growth in most postwar years was slower than that of all Southeast Asian nations. And, although immigration was encouraged, the resistance to immigration that characterized Southeast Asian countries was shared by Australia with respect to all but North Western Europeans, an "acceptable" category progressively widened by dint of curcumstances to include Eastern Europeans, then Southern Europeans, then certain Middle Eastern peoples, and finally Asians and Latin Americans. Australia shared with Southeast Asian nations the concern with big-city growth and like the Southeast Asian nations searched for appropriate policies to contain this growth and promote that of smaller cities and towns. This search stopped in the 1970s when the report of the National Population showed that accepted projections of the populations of Sydney and Melbourne had

  2. What causes southeast Australia's worst droughts? (United States)

    Ummenhofer, Caroline C.; England, Matthew H.; McIntosh, Peter C.; Meyers, Gary A.; Pook, Michael J.; Risbey, James S.; Gupta, Alexander Sen; Taschetto, Andréa S.


    Since 1995, a large region of Australia has been gripped by the most severe drought in living memory, the so-called ``Big Dry''. The ramifications for affected regions are dire, with acute water shortages for rural and metropolitan areas, record agricultural losses, the drying-out of two of Australia's major river systems and far-reaching ecosystem damage. Yet the drought's origins have remained elusive. For Southeast Australia, we show here that the ``Big Dry'' and other iconic 20th Century droughts, including the Federation Drought (1895-1902) and World War II drought (1937-1945), are driven by Indian Ocean variability, not Pacific Ocean conditions as traditionally assumed. Specifically, a conspicuous absence of Indian Ocean temperature conditions conducive to enhanced tropical moisture transport has deprived southeastern Australia of its normal rainfall quota. In the case of the ``Big Dry'', its unprecedented intensity is also related to recent higher temperatures.

  3. Climate change and wind power in Australia

    Energy Technology Data Exchange (ETDEWEB)

    Millais, C. [Greenpeace Australia Pacific, Sydney (Australia)


    The article represents a stern criticism of Australia's attitude to climate change. Its climate change policy is described as 'Neanderthal'. The Australian government is said to be strongly opposed to ratification of the Kyoto Protocol. The Government's policy appears to be driven by vested interests in fossil fuels. A list of eight flaws in Australia's 2% renewables target is given; the target is said to be far too small for a country with so much renewables potential. However, investment in the country's enormous wind power potential is increasing and targets are given; six reasons why Australia needs to invest in wind power are given. It is suggested that by the end of this decade, 10% of Australia's electricity could come from wind power - a web site address giving further details is given.

  10. The First World War years of Sydney Domville Rowland: an early case of possible laboratory-acquired meningococcal disease. (United States)

    Wever, Peter C; Hodges, A J


    Sydney Domville Rowland was a bacteriologist and staff member at the Lister Institute of Preventive Medicine when the First World War broke out in 1914. Following a request to the Director of the Lister Institute to staff and equip a mobile field laboratory as quickly as possible, Rowland was appointed to take charge of No. 1 Mobile Laboratory and took up a temporary commission at the rank of Lieutenant in the Royal Army Medical Corps. On 9 October 1914, Rowland set out for the European mainland and was subsequently attached to General Headquarters in Saint-Omer, France (October 1914-June 1915), No. 10 Casualty Clearing Station in Lijssenthoek, Belgium (June 1915-February 1916, during which period he was promoted Major), and No. 26 General Hospital in Étaples, France (February 1916-March 1917). His research focused on gas gangrene, typhoid fever, trench fever, wound infection and cerebrospinal fever. In February of 1917, while engaged in identifying meningococcal carriers, Rowland contracted cerebrospinal meningitis to which he succumbed at age 44 on 6 March 1917. His untimely death might have been caused by laboratory-acquired meningococcal disease, especially since Rowland's work with Neisseria meningitidis isolates had extended beyond routine laboratory techniques and included risk procedures like immunisation of rabbits with pathogenic strains isolated from cerebrospinal fluid. Currently, microbiology laboratory workers who are routinely exposed to N. meningitidis isolates are recognised as a population at increased risk for meningococcal disease, for which reason recommended preventive measures include vaccination and handling of isolates within a class II biosafety cabinet.

    The new generation of reusable launch vehicles represented by ESA's Hermes and HOTOL, NASA's National Aerospace Plane, and the DFVLR's Saenger, promises to radically alter the economic basis of space flight by allowing such operations as the on-orbit servicing of satellites. Attention is presently drawn to the opportunities that arise for Australia's aerospace industry from the availability in Australia of two wind tunnel facilities capable of furnishing the requisite hypersonic aerothermodynamics testing capabilities for these vehicles' development.

  12. Modelling persistence in annual Australia point rainfall

    Directory of Open Access Journals (Sweden)

    J. P. Whiting


    Full Text Available Annual rainfall time series for Sydney from 1859 to 1999 is analysed. Clear evidence of nonstationarity is presented, but substantial evidence for persistence or hidden states is more elusive. A test of the hypothesis that a hidden state Markov model reduces to a mixture distribution is presented. There is strong evidence of a correlation between the annual rainfall and climate indices. Strong evidence of persistence of one of these indices, the Pacific Decadal Oscillation (PDO, is presented together with a demonstration that this is better modelled by fractional differencing than by a hidden state Markov model. It is shown that conditioning the logarithm of rainfall on PDO, the Southern Oscillation index (SOI, and their interaction provides realistic simulation of rainfall that matches observed statistics. Similar simulation models are presented for Brisbane, Melbourne and Perth. Keywords: Hydrological persistence,hidden state Markov models, fractional differencing, PDO, SOI, Australian rainfall

  13. Return migration from Australia: a case study. (United States)

    Lukomskyj, O; Richards, P


    "The study investigates the departure from Australia of former settlers who arrived during the 1980 calendar year. The 1980 settler arrival cohort [consists] of 75,167 visaed migrants.... The study has three main aims: (i) to analyse departures from Australia of the 1980 settler arrival cohort with a view to gauging the success of Australia's immigration program in retaining settlers; (ii) to examine the retention rates of settlers with respect to characteristics...including age, sex, marital status, country of last residence, and settler eligibility category; and (iii) to consider implications of the findings." Australia's present immigration policy is discussed, previous research on return migration from Australia is summarized, and a detailed analysis of the departure data is presented. "This study found that by August 1984, 12.4 per cent of non-refugee settlers who arrived in Australia during 1980 had departed permanently but that only 0.6 per cent of the 1980 refugee cohort had done so." These figures represent a decline in immigrant departure rates since the 1960s and early 1970s. Small differences in departure rates by place of birth, age, and marital status, which may have demographic consequences if sustained over time, are noted. (SUMMARY IN FRE AND SPA)

  14. How rich is Australia's minerals endowment and is it adequate to sustain a major role in meeting international demand? (United States)

    Lambert, I. B.


    Dr Ian Lambert, Geoscience Australia and Secretary General 34th International Geological Congress Australia has comparative advantages in production of mineral commodities compared to most other countries. These stem from its rich and diverse mineral endowment; availability of regional scale (pre-competitive) geoscience information to lower the risks of exploration; advances in exploration, mining and processing technologies; skilled work force; generally benign physical conditions; and low population density. Building on these strengths, Australia is a major producer and exporter of a wide range of mineral and energy commodities to global markets. Given that demand for most major commodities is likely to continue, and that there will be growing markets for some other commodities, Australia needs to have a strategic view of what is likely to be available for mining. Further, Australia (and the world) needs to be attuned to issues that need to be faced in meeting international demand for commodities in the long term. This presentation outlines how Australia's national minerals inventory is compiled. It discusses trends for Australia's identified mineral resources for major commodities, and how these compare with other major mining nations. It then considers some significant issues in relation to sustaining a strong mining sector - in the medium to long term this requires a strategic approach to achieve goals such as more effective/lower risk exploration particularly in greenfields regions; well-Informed decisions on mining proposals; ongoing significant improvements in efficiencies of energy, water and land use.

  15. Paediatric bacteraemias in tropical Australia. (United States)

    Er, Jeremy; Wallis, Peter; Maloney, Samuel; Norton, Robert


    Bacteraemias in children are an important cause of morbidity and mortality. Knowledge of local epidemiology and trends is important to inform practitioners of likely pathogens in the sick child. This study aimed to determine trends over time in pathogenic organisms causing paediatric bacteraemia in North Queensland and to audit a hospital's blood culture results with respect to contamination rate. This was a retrospective review of 8385 blood cultures collected from children attending a tertiary centre in North Queensland over a 10-year period (2001-2010). There were 696 positive blood cultures (8.3%) with 70 different bacterial species detected. Gram-positive and Gram-negative bacteria accounted for 48.6% and 51.4% of isolates, respectively. Overall, bacteraemia accounted for 4.7 per 1000 admissions. The rate of contamination was 60.6% among positive blood cultures and 5.0% for all blood cultures sampled. These results were compared with previous published reports. Notable differences were seen in the frequencies of Salmonella and group A Streptococcus bacteraemias in North Queensland when compared with other reports. There was also a decline in vaccine-preventable infections such as S. pneumoniae and an increasing trend of community-acquired MRSA bacteraemia. This study has demonstrated the unique profile of causative pathogens of paediatric bacteraemias in tropical Australia. In light of the increasing prevalence of MRSA, empiric treatment for sepsis for children in this region needs to be reconsidered. © 2014 The Authors.

  17. Revolution then evolution: the advance of health economic evaluation in Australia. (United States)

    Lopert, Ruth; Viney, Rosalie


    All governments face immense challenges in providing affordable healthcare for their citizens, and the diffusion of novel health technologies is a key driver of growth in expenditure for many. Although important methodological and process variations exist around the world, health economic evaluation is increasingly seen as an important tool to support decision-making around the introduction of new health technologies, interventions and programmes in countries of varying stages of economic development. In Australia, the assessment of the comparative cost-effectiveness of new medicines proposed for subsidy under the country's national drug subsidy programme, the Pharmaceutical Benefits Scheme, was introduced in the late 1980s and became mandatory in 1993, making Australia the first country to introduce such a requirement nationally. Since then the use of health economic evaluation has expanded and been applied to support decision-making across a broader range of health technologies, as well as to programmes in public health.

    Harris, J B; Sutherland, S; Zar, M A


    1 The effects on mammalian autonomic neuromuscular transmission of the crude venom of the female Sydney funnel-web spider Atrax robustus, have been investigated.2 At doses of 10 mug/ml or lower the indirectly elicited twitch-like responses of the rat anococcygeus preparation were inhibited. At doses greater than 10 mug/ml there was an initial reduction in the twitch-like response followed by a sustained contracture of the tissue.3 The long-lasting contracture caused by the venom was abolished by the application of phentolamine. It was virtually non-existent in muscle preparations isolated from reserpine-treated rats.4 In the presence of tetrodotoxin the contracture was smaller and less well maintained than in its absence.5 The venom caused a small reduction in the amplitude of the indirectly elicited twitch-like response of the longitudinal muscle of the guinea-pig ileum, followed by an increase in the tone of the preparation. The increase in tone was maintained for several minutes and was rapidly abolished by the application of atropine. The presence of venom did not affect control responses to either histamine or acetylcholine.6 Inhibitory transmission in the rat anococcygeus preparation was unaffected by the venom.7 The neurally-mediated twitch-like responses of both guinea-pig and rat vas deferens were inhibited by the venom at doses below 10 mug/ml. At higher doses the inhibition was accompanied by spontaneous contractions, and at doses in excess of 100 mug/ml the inhibition of twitch-like responses was transient and was followed by a potentiation of the motor response and extensive spontaneous activity. The preparation became quiescent 20 min after the application of venom and the evoked response was abolished after 60 min.8 The venom had qualitatively similar effects on motor transmission in the human vas deferens as on the rat and guinea-pig preparations. However, the human preparations were 50 to 100 times more sensitive to the effects of the venom.

  20. Tick-borne infectious diseases in Australia. (United States)

    Graves, Stephen R; Stenos, John


    Tick bites in Australia can lead to a variety of illnesses in patients. These include infection, allergies, paralysis, autoimmune disease, post-infection fatigue and Australian multisystem disorder. Rickettsial (Rickettsia spp.) infections (Queensland tick typhus, Flinders Island spotted fever and Australian spotted fever) and Q fever (Coxiella burnetii) are the only systemic bacterial infections that are known to be transmitted by tick bites in Australia. Three species of local ticks transmit bacterial infection following a tick bite: the paralysis tick (Ixodes holocyclus) is endemic on the east coast of Australia and causes Queensland tick typhus due to R. australis and Q fever due to C. burnetii; the ornate kangaroo tick (Amblyomma triguttatum) occurs throughout much of northern, central and western Australia and causes Q fever; and the southern reptile tick (Bothriocroton hydrosauri) is found mainly in south-eastern Australia and causes Flinders Island spotted fever due to R. honei. Much about Australian ticks and the medical outcomes following tick bites remains unknown. Further research is required to increase understanding of these areas.

  1. Does Lyme disease exist in Australia? (United States)

    Collignon, Peter J; Lum, Gary D; Robson, Jennifer Mb


    There is no convincing evidence that classic Lyme disease occurs in Australia, nor is there evidence that the causative agent, Borrelia burgdorferi, is found in Australian animals or ticks. Lyme disease, however, can be acquired overseas but diagnosed in Australia; most people presenting with laboratory-confirmed Lyme disease in Australia were infected in Europe. Despite the lack of evidence that Lyme disease can be acquired in Australia, growing numbers of patients, their supporters, and some politicians demand diagnoses and treatment according to the protocols of the "chronic Lyme disease" school of thought. Antibiotic therapy for chronic "Lyme disease-like illness" can cause harm to both the individual (eg, cannula-related intravenous sepsis) and the broader community (increased antimicrobial resistance rates). Until there is strong evidence from well performed clinical studies that bacteria present in Australia cause a chronic debilitating illness that responds to prolonged antibiotics, treating patients with "Lyme disease-like illness" with prolonged antibiotic therapy is unjustified, and is likely to do much more harm than good.

  2. Toward a sustainable energy future in Australia

    Energy Technology Data Exchange (ETDEWEB)

    Kinrade, P. [Melbourne Univ., VIC (Australia). School of Anthropology, Geography and Environmental Studies; Marsden Jacob Associates, Camberwell, VIC (Australia)


    Envisioning Australia's energy future through a 'strong sustainability' framework would see a future that is based on the efficient and equitable use of energy, sourced from a diverse range of renewable, distributed energy systems. Supply and use of this energy would produce low or zero greenhouse gases and other emissions. A sustainable energy future in Australia would also see a shift in focus to meeting energy service needs (rather increased energy consumption). Importantly, energy users would be empowered, being knowledgeable and active participants in energy markets. In reality, Australia currently stands a long way from this vision: energy-related greenhouse gas emissions are growing rapidly; take up of renewable energy is slow, particularly of distributed energy forms such as solar photovoltaics; and energy intensity of the economy is declining at a slower rate than many other OECD economies. Furthermore, Australians consume far more energy than is required to meet the service needs of even modern lifestyles. If Australia is to move towards a sustainable energy future, then significant barriers must be overcome including aspects of Australia's economic structure, a misdirected energy market reform process and a lack of visionary thinking by decision makers. Hope comes in the form of the broader Australian community who intuitively support a sustainable energy vision but currently lack the institutional, market and regulatory support to make it happen.

  3. Assessing preferences of beach users for certain aspects of weather and ocean conditions: case studies from Australia (United States)

    Zhang, Fan; Wang, Xiao Hua


    Three well-known Australian beaches, Surfers Paradise Beach (Gold Coast), Narrowneck Beach (Gold Coast) and Bondi Beach (Sydney), were selected for analysis of beach user preferences for certain weather and ocean conditions. Regression methods were used to determine how the numbers of visitors to these beaches are affected by these conditions. Actual visitor numbers were counted at three times during the day over several months at each beach with the aid of web cameras. The corresponding weather and ocean conditions were obtained from the Australian Bureau of Meteorology and local government agencies. Weekly and seasonal factors were also considered. The conditions preferred by beach users, as found in this study, are: no precipitation, higher temperatures, light-to-moderate wind speed (less than 30 km/h) and low wave height (up to 1.25 m). This study, the first to provide an analysis of beach user preferences for both weather and ocean conditions, shows that ocean conditions play a significant role in explaining the demand for beach recreation in Australia. It is therefore necessary for tourism management authorities or local governments to provide accurate and timely weather and ocean information to local, domestic and international beach users.

    To monitor genetic diversity and environmental contamination in eastern Australia, toxicity studies have employed the sensitive benthic amphipod Melita plumulosa. The goal of this study was to examine the genetic and life-history variability of natural populations of M. plumulosa from the Parramatta (polluted) and Hawkesbury (unpolluted) Rivers. The underlying genetics of the populations in these distinct waterways was examined at one mitochondrial (cytochrome c oxidase subunit I (COI)) and one nuclear (ribosomal internal transcribed spacer region 1 (ITS1)) locus. Seven unique haplotypes for COI were found amongst animals from the Parramatta River, while animals from the Hawkesbury River showed a complete absence of genetic variation at this locus. At ITS1 a total of two sequence variants were found amongst Parramatta River amphipods and three sequence variants among Hawkesbury River animals, with no common variants across the two river systems. To establish whether genetic differences were associated with organismal responses to toxicant exposure, two life-history trait variables (female head length as an estimator of amphipod size and female fecundity) were analyzed. Life-history trait analyses showed that females from the Hawkesbury River were significantly larger and more fecund. These data have critical implications for toxicity tests, the use of laboratory cultures for testing purposes, and environmental contamination in Sydney Harbor.

  6. Are gluten-free foods healthier than non-gluten-free foods? An evaluation of supermarket products in Australia. (United States)

    Wu, Jason H Y; Neal, Bruce; Trevena, Helen; Crino, Michelle; Stuart-Smith, Wendy; Faulkner-Hogg, Kim; Yu Louie, Jimmy Chun; Dunford, Elizabeth


    Despite tremendous growth in the consumption of gluten-free (GF) foods, there is a lack of evaluation of their nutritional profile and how they compare with non-GF foods. The present study evaluated the nutritional quality of GF and non-GF foods in core food groups, and a wide range of discretionary products in Australian supermarkets. Nutritional information on the Nutrition Information Panel was systematically obtained from all packaged foods at four large supermarkets in Sydney, Australia in 2013. Food products were classified as GF if a GF declaration appeared anywhere on the product packaging, or non-GF if they contained gluten, wheat, rye, triticale, barley, oats or spelt. The primary outcome was the 'Health Star Rating' (HSR: lowest score 0.5; optimal score 5), a nutrient profiling scheme endorsed by the Australian Government. Differences in the content of individual nutrients were explored in secondary analyses. A total of 3213 food products across ten food categories were included. On average, GF plain dry pasta scored nearly 0.5 stars less (Pgluten intolerance.

  7. Population genetics and management units of invasive common carp Cyprinus carpio in the Murray-Darling Basin, Australia. (United States)

    Haynes, G D; Gilligan, D M; Grewe, P; Nicholas, F W


    Common carp Cyprinus carpio were introduced into Australia on several occasions and are now the dominant fish in the Murray-Darling Basin (MDB), the continent's largest river system. In this study, variability at 14 microsatellite loci was examined in C. carpio (n = 1037) from 34 sites throughout the major rivers in the MDB, from 3 cultured populations, from Prospect Reservoir in the Sydney Basin and from Lake Sorrell in Tasmania. Consistent with previous studies, assignment testing indicated that the Boolara, Yanco and koi strains of C. carpio are present in the MDB. Unique to this study, however, the Prospect strain was widely distributed throughout the MDB. Significant genetic structuring of populations (Fisher's exact test, AMOVA and distribution of the different strains) amongst the MDB sub-drainages was detected, and was strongly associated with contemporary barriers to dispersal and population history. The distributions of the strains were used to infer the history of introduction and spread of C. carpio in the MDB. Fifteen management units are proposed for control programmes that have high levels of genetic diversity, contain multiple interbreeding strains and show no evidence of founder effects or recent population bottlenecks.

  8. From Potts Hill (Australia) to Pune (India): The journey of a radio astronomer (United States)

    Swarup, Govind


    In this paper I recapitulate my initiation into the field of radio astronomy during 1953-1955 at CSIRO, Australia; the transfer of thirty-two parabolic dishes of six-feet (1.8-m) diameter from Potts Hill, Sydney, to India in 1958; and their erection at Kalyan, near Bombay (Mumbai), in 1963-1965. The Kalyan Radio Telescope was the first modern radio telescope built in India. This led to the establishment of a very active radio astronomy group at the Tata Institute of Fundamental Research, which subsequently built two world-class radio telescopes during the last forty years and also contributed to the development of an indigenous microwave antenna industry in India. The Ooty Radio Telescope, built during 1965-1970, has an ingenious design which takes advantage of India's location near the Earth's Equator. The long axis of this 530 m × 30 m parabolic cylinder was made parallel to the Equator, by placing it on a hill with the same slope as the geographic latitude (11 degrees), thus allowing it to track celestial sources continuously for 9.5 hours every day. By utilizing lunar occultations, the telescope was able to measure the angular sizes of a large number of faint radio galaxies and quasars with arc-second resolution for the first time. Subsequently, during the 1990s, the group set up the Giant Metrewave Radio Telescope (GMRT) near Pune in western India, in order to investigate certain astrophysical phenomena which are best studied at decimetre and metre wavelengths. The GMRT is an array of thirty fully-steerable parabolic dishes of 45 m diameter, which operates at several frequencies below 1.43 GHz. These efforts have also contributed to the recent international proposal to construct the Square Kilometre Array (SKA).

  9. Migrants and the transformation of local neighbourhoods: A study of the socioeconomic transformation of Lidcombe, Australia

    Directory of Open Access Journals (Sweden)

    Franklin OBENG-ODOOM


    Full Text Available A major contributor to negative attitudes towards migrants is that they exert pressure on the facilities of the host communities without making any (substantial contribution to the host economy and society. This negative sentiment is particularly acute in cities, where pressure on amenities is concentrated and more visible. In turn, migrant neighbourhoods are particularly despised. Migration experiences in the Rookwood Cemetery area of Sydney, Australia, widely regarded as the “largest necropolis in the southern hemisphere”, however, challenge this stereotypical view. This migrant neighbourhood is the site of vibrant and diverse migration and migrant (especially Korean activities never before seen in the history of the area, which is now called Lidcombe. Drawing on multiple sources of evidence, including archival research at local libraries, discussion with long-time residents of the neighbourhood and visual ethnography (analysed from the historical-structural perspective in migration studies, this study offers a history of Lidcombe and appraises its twenty-first-century migration experiences. By doing so, it highlights the demographic, social and economic changes to emphasise the contribution of migrants to the regeneration of a “dead city” and also to contest inherited stereotypes of migrants that often lead to racial scapegoating and misrepresentation as “parasites”, “criminals” and a “drain” on the host economy. Overall, this case study suggests that migrants can and often do transform the spaces they occupy in ways that make a positive and lasting contribution to the host economy and society more generally. This is an important lesson for European countries facing the “migrant crisis” to consider, as it also is for politicians around the world seeking to wall out migrants to protect host economies and societies.

    Hartley, Lisa; Fleay, Caroline; Tye, Marian E


    This paper explores the engagement in physical activity as a potential coping strategy for asylum seekers living in the Australian community without the right to work and with prolonged uncertainty, and benefits or barriers to undertaking such activity. Semi-structured in-depth interviews were held with 29 asylum seekers who had arrived to Australia by boat and were living in the community in the cities of Perth, Sydney or Melbourne in July-October 2013 after their release from immigration detention. The ratio of the numbers of men and women interviewed (23 men and 6 women) was comparable to the ratio of men and women who came by boat to Australia seeking asylum in 2012-2013. Nine participants reported that they participated in physical activity as a coping strategy. Seven other participants were so worried about their future and their families that they did not have the mental or physical energy to engage in physical activity. A further six wanted to participate in physical activity but faced a number of barriers to doing so. The seven remaining participants were either not asked about their physical activity engagement because they focused their discussion on other challenges or did not elaborate on why they were not engaging in physical activity. The findings suggest that physical activity, coupled with other coping strategies, are important for some asylum seekers in trying to manage the distress of being denied the right to work and living with prolonged uncertainty. In addition, these findings highlight the critical barrier that government policy plays in disabling engagement in physical activity, which further compounds social exclusion. This includes the lack of welfare support provided, which hinders people's financial ability to access activities and support in the community. © 2017 John Wiley & Sons Ltd.

    Foroughi, Forough; Lam, Alfred K-Y; Lim, Megan S C; Saremi, Nassim; Ahmadvand, Alireza


    The infodemiological analysis of queries from search engines to shed light on the status of various noncommunicable diseases has gained increasing popularity in recent years. The aim of the study was to determine the international perspective on the distribution of information seeking in Google regarding "cancer" in major English-speaking countries. We used Google Trends service to assess people's interest in searching about "Cancer" classified as "Disease," from January 2004 to December 2015 in Australia, Canada, New Zealand, the United Kingdom, and the United States. Then, we evaluated top cities and their relative search volumes (SVs) and country-specific "Top searches" and "Rising searches." We also evaluated the cross-country correlations of SVs for cancer, as well as rank correlations of SVs from 2010 to 2014 with the incidence of cancer in 2012 in the abovementioned countries. From 2004 to 2015, the United States (relative SV [from 100]: 63), Canada (62), and Australia (61) were the top countries searching for cancer in Google, followed by New Zealand (54) and the United Kingdom (48). There was a consistent seasonality pattern in searching for cancer in the United States, Canada, Australia, and New Zealand. Baltimore (United States), St John's (Canada), Sydney (Australia), Otaika (New Zealand), and Saint Albans (United Kingdom) had the highest search interest in their corresponding countries. "Breast cancer" was the cancer entity that consistently appeared high in the list of top searches in all 5 countries. The "Rising searches" were "pancreatic cancer" in Canada and "ovarian cancer" in New Zealand. Cross-correlation of SVs was strong between the United States, Canada, and Australia (>.70, P<.01). Cancer maintained its popularity as a search term for people in the United States, Canada, and Australia, comparably higher than New Zealand and the United Kingdom. The increased interest in searching for keywords related to cancer shows the possible effectiveness

    Full Text Available Aim. The primary objective of the study was to assess the iodine nutritional status, and its effect on thyroid function, of pregnant women in a private obstetrical practice in Sydney. Methods. It was a cross-sectional study undertaken between November 2007 and March 2009. Blood samples were taken from 367 women at their first antenatal visit between 7 and 11 weeks gestation for measurement of thyroid stimulating hormone (TSH and free thyroxine (FT4 levels and spot urine samples for urinary iodine excretion were taken at the same time as blood collection. Results. The median urinary iodine concentration (UIC for all women was 81 μg/l (interquartile range 41–169 μg/l. 71.9% of the women exhibited a UIC of <150 μg/l. 26% of the women had a UIC <50 μg/l, and 12% had a UIC <20 μg/l. The only detectable influences on UIC were daily milk intake and pregnancy supplements. There was no statistically significant association between UIC and thyroid function and no evidence for an effect of iodine intake on thyroid function. Conclusions. There is a high prevalence of mild to moderate iodine deficiency in women in Western Sydney but no evidence for a significant adverse effect on thyroid function. The 6.5% prevalence of subclinical hypothyroidism is unlikely to be due to iodine deficiency.

    Full Text Available Abstract Background A sharp reduction in heroin supply in Australia in 2001 was followed by a large but transient increase in cocaine use among injecting drug users (IDU in Sydney. This paper assesses whether the increase in cocaine use among IDU was accompanied by increased rates of violent crime as occurred in the United States in the 1980s. Specifically, the paper aims to examine the impact of increased cocaine use among Sydney IDU upon police incidents of robbery with a weapon, assault and homicide. Methods Data on cocaine use among IDU was obtained from the Illicit Drug Reporting System (IDRS. Monthly NSW Police incident data on arrests for cocaine possession/use, robbery offences, homicides, and assaults, were obtained from the Bureau of Crime Statistics and Research. Time series analysis was conducted on the police data series where possible. Semi-structured interviews were conducted with representatives from law enforcement and health agencies about the impacts of cocaine use on crime and policing. Results There was a significant increase in cocaine use and cocaine possession offences in the months immediately following the reduction in heroin supply. There was also a significant increase in incidents of robbery where weapons were involved. There were no increases in offences involving firearms, homicides or reported assaults. Conclusion The increased use of cocaine among injecting drug users following the heroin shortage led to increases in violent crime. Other States and territories that also experienced a heroin shortage but did not show any increases in cocaine use did not report any increase in violent crimes. The violent crimes committed did not involve guns, most likely because of its stringent gun laws, in contrast to the experience of American cities that have experienced high rates of cocaine use and violent crime.

    Full Text Available Environmental pollution is one of the main restrictions of sustainable development. We examine whether or not freight transport is sensitive of the environment in Australia, particularly in the state of Victoria. Because, freight transports is one of the significant factors of environmental pollution. In the study we discuss the decision taken by the government of Victoria; and what kind of measurement is applied by the government. We also discuss which policy should be followed to achieve green transportation. The aim of the study is to determine the effects of environmental measurement on growing of the transport sector. The economics of Australia has a structure growing fast, in order to parallel the increasing growth of the transport sector. It tries to apply Kyoto protocol to the transport sector. In conclusion, the environmental pollution and CO2 emissions decrease in Australia although the transport sector grows day by day.

  15. Multiculturalism and transcultural nursing in Australia. (United States)

    Gorman, D


    The author looks at Australia's multicultural society and identifies the failure of the nursing profession to provide nursing services that meet the commitment of Australia to preserve the cultural backgrounds and meet the needs of the people nurses serve. The author suggests ways in which this problem can be addressed. It is argued that there is a need to ensure that transcultural nursing services are recognized and made accessible to people from diverse cultural backgrounds. Nurses need educational preparation to provide them with the knowledge, skills, and attitudes essential to work with people from different cultures. Moreover, the cultural profile of the nursing profession should approximate those served. Nurses today must recognize these critical needs and be committed to provide transcultural nursing care that is so essential in Australia's multicultural society.

    Harrison, Keith; Peek, John; Chapman, Michael; Bowman, Mark


    Assisted reproductive technology (ART) clinics in Australia and New Zealand are accredited and licensed against a Code of Practice audited by certifying bodies accredited by the Joint Accreditation System for Australia and New Zealand (JAS-ANZ). The system is administered by the Reproductive Technology Accreditation Committee (RTAC) of the Fertility Society of Australia. To review the incidence of variances and findings identified by certifying bodies in Australian and New Zealand ART clinics within the currency of a single version of the Code of Practice. Retrospective analysis of certifying body findings against the RTAC Code of Practice incorporating 15 Critical Criteria audited annually and 16 Good Practice Criteria including a Quality Management System audited over a three year cycle. The incidence of clinics with variances against the Critical Criteria fell from 77 to 14% over two years, as did the mean number of variances per clinic which fell from 1.54 to 0.14. Implementation of the RTAC accreditation system in Australia and New Zealand has contributed to steady improvement in standards and a reduction in risk in ART treatments. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

  18. The Creeping Blight of Islamophobia in Australia

    Directory of Open Access Journals (Sweden)

    Linda Briskman


    Full Text Available In the latter months of 2014, following events in faraway Iraq and Syria, Australia responded forcefully at home. The manufactured fear of a terrorist attack resulted in police raids, increased counter-terrorism legislation and scare campaigns to alert the public to 'threat'. Although Islamophobia rose in Australia after 2001 it has been latent in recent years. It is on the rise again with collateral damage from government measures including verbal and physical attacks on Australian Muslims. Vitriol is also directed at asylum seekers and refugees. Media, government and community discourses converge to promote Islam as dangerous and deviant.

The study reported here replicates a US reengineering study in an Australian context by surveying large public and private sector Australian organisations. The study makes three main contributions by: (1 presenting a picture of BPR practices in Australia, (2 clarifying factors critical to the success of reengineering projects in Australia, and (3 providing a comparison of factors leading to success in Australian BPR projects with those found in the US.

  20. Roaming yuppies: Hong Kong migration to Australia. (United States)

    Wong, S


    "Hong Kong has been the top source for Asian migration to Australia in recent years. The majority of the Hong Kong migrants are young, educated professionals. Using survey data conducted in Hong Kong on emigration tendencies, this article analyzes why they are leaving Hong Kong, what attracts them to Australia, and what impact this influx has on Australian society. It is speculated that this movement may create an enduring change in the identity of emigrant Hong Kongers and have a wider significance in the contradictory currents of geopolitics and geoeconomics which are simultaneously encouraging and resisting migration."
