    Australia's black coal resources rank in the top five globally, around 50% of which are located in the sedimentary basins of Queensland. The Bowen Basin is the most prolific coal repository, hosting over 60% of the currently established resource inventory. Large volumes of thermal coal are present in the Surat and Galilee basins as well as small extensional and pull apart basins such as Blair Athol and Tarong. The article examines Queensland's coal industry from a government perspective. It first discusses the current coal market, then introduces the concept of inventory coal and explains the Australia Joint Ore Reserves Committee (JORC) code - a resource evaluation system. The stratigraphy of each of Queensland's coal basins is then discussed in sections headed Permian coals, Triassic coals, Jurassic and Cretaceous coals, and Tertiary coals. 3 figs.

    In 2011, Queensland dialysis services experienced two unprecedented natural disasters within weeks of each other. Floods in south-east Queensland and Tropical Cyclone Yasi in North Queensland caused widespread flooding, property damage and affected the provision of dialysis services, leading to Australia's largest evacuation of dialysis patients. This paper details the responses to the disasters and examines what worked and what lessons were learnt. Recommendations are made for dialysis units in relation to disaster preparedness, response and recovery. © 2012 The Authors. Nephrology © 2012 Asian Pacific Society of Nephrology.

    Development of any new profession is dependent on the development of a special body of knowledge that is the domain of the profession. Key to this is research. Following sustained lobbying, the Queensland Government agreed to establish an emergency medicine research fund as part of an Enterprise Bargaining Agreement in 2006. That fund is managed by the Queensland Emergency Medicine Research Foundation. The present article describes the strategic approaches of the Foundation in its first 3 years, the application of research funds, and foreshadows an evaluative framework for determining the strategic value of this investment. The Foundation has developed a range of personnel and project support funding programmes, and competition for funding has increased. Ongoing evaluation will seek to determine the effectiveness of the current funding strategy on improving the effectiveness of research performance. It will also evaluate the clinical and organizational outcomes.

    Rehabilitation of marine turtles in Queensland has multifaceted objectives. It treats individual animals, serves to educate the public, and contributes to conservation. We examined the outcome from rehabilitation, time in rehabilitation, and subsequent recapture and restranding rates of stranded marine turtles between 1996 and 2013 to determine if the benefits associated with this practice are cost-effective as a conservation tool. Of 13,854 marine turtles reported as stranded during this 18-year period, 5,022 of these turtles were stranded alive with the remainder verified as dead or of unknown condition. A total of 2,970 (59%) of these live strandings were transported to a rehabilitation facility. Overall, 1,173/2,970 (39%) turtles were released over 18 years, 101 of which were recaptured: 77 reported as restrandings (20 dead, 13 alive subsequently died, 11 alive subsequently euthanized, 33 alive) and 24 recaptured during normal marine turtle population monitoring or fishing activities. Of the turtles admitted to rehabilitation exhibiting signs of disease, 88% of them died, either unassisted or by euthanasia and 66% of turtles admitted for unknown causes of stranding died either unassisted or by euthanasia. All turtles recorded as having a buoyancy disorder with no other presenting problem or disorder recorded, were released alive. In Queensland, rehabilitation costs approximately $1,000 per animal per year admitted to a center, $2,583 per animal per year released, and $123,750 per animal per year for marine turtles which are presumably successfully returned to the functional population. This practice may not be economically viable in its present configuration, but may be more cost effective as a mobile response unit. Further there is certainly benefit giving individual turtles a chance at survival and educating the public in the perils facing marine turtles.

    2013-09-01

    The waste and recycling sector has been identified as a green industry and, as such, jobs within this sector may be classed as 'green jobs'. Many governments have seen green jobs as a way of increasing employment, particularly during the global financial crisis. However, the methods used to define and quantify green jobs directly affect the quantification of these green jobs. In December 2010, Queensland introduced a waste strategy that stated intent to increase green jobs within the waste sector. This article discusses the milieu and existing issues associated with quantifying green jobs within Queensland's waste and recycling sector, and provides a review of the survey that has sought to quantify the true size of the Queensland industry sector. This research has identified nearly 5500 jobs in Queensland's private waste management and recycling sector, which indicates that official data do not accurately reflect the true size of the sector.

    Spread of the amphibian chytrid fungus Batrachochytrium dendrobatidis (Bd), which causes chytridiomycosis, has resulted in the extinction of frogs, but the distribution of Bd is incompletely known. We trialled the survey protocol for Bd by attempting to systematically map its distribution in Queensland, Australia. Bd was easily detected in known infected areas, such as the Wet Tropics and South East Queensland. It was not detected in bioregions adjacent to, but inland from or to the north of, infected regions: Einasleigh Uplands and Cape York adjacent to the infected Wet Tropics; and Brigalow Belt South adjacent to the infected South East Queensland bioregion. These regions where Bd was not detected have bordered infected regions for between 15 yr (in northern Queensland) and 30 yr (in southern Queensland), and so they define the geographical limits of Bd with regard to the long-term environmental conditions in Queensland. The Gulf Plains, a bioregion distant from infected bioregions, was also negative. Bd was confined to rainforest and bordering habitats, such as wet eucalypt forests. Infections were largely confined to permanent water-associated species, consistent with this being an important cause of this group having the greatest declines. Our data supports biogeographic climatic models that show much of inland and northern Australia to be too hot and dry to support Bd. As there is limited opportunity for Bd to spread further in Queensland, the priority for management is reducing the impact of Bd in affected populations and assisting frogs to disperse into their former distributions. Given that the survey protocol has been applied successfully in Australia it may be useful for mapping the distribution of Bd in other parts of the world.

    Full Text Available The plant fossil genera Umkomasia Thomas 1933 and Pteruchus Thomas 1933 emend. Townrow 1962 are known chiefly from the Middle and Upper Triassic of Gondwana. The structure of these fructifications has been conjectural, some being identified as pinnate, others as helically arranged. Specimens from the Ladinian-lower Norian of Queensland (northeastern Australia show that the female and male fructifications - U. geminata (Shirley 1898 Rigby in Playford et al. 1982 emend. nov. and P. dubius Thomas 1933 emend. Townrow 1962, respectively - have a bipinnate structure. Those fructifications and the bipinnate leaf, Dicroidium feistmantelii (Johnston 1894 Gothan 1912, probably all belonged to the same parent plant. It was first suggested by John Townrow in 1962 that the sporangial heads of P. dubius have a pinnate structure; this character is confirmed herein. Pteruchus is recorded for the first time from the Carnian Tarong Basin, Queensland.

    It is currently hypothesised that a combination of genetic and environmental factors underlies the development of idiopathic isolated dystonia (IID). In this study, we examined several possible environmental or other non-genetic factors that may influence the risk for IID in Queensland, Australia. We surveyed several environmental exposures, lifestyle factors, medical and family histories to investigate potential risk factors for IID. Associations between putative risk factors and IID were assessed using a total of 184 dystonia patients and 1048 neurologically-normal control subjects sampled from Queensland between 2005 and 2012. Our analyses revealed that anxiety disorders, depression, tremor, cigarette smoking and head injuries with a loss of consciousness were associated with increased risk for IID (prisk for dystonia increased with higher cigarette smoking pack-year quartiles in our analyses. Our results suggest possible environmental factors that influence the development of IID and complement the findings of similar dystonia risk factor studies. Further investigation defining the environmental and other non-genetic risk factors for IID may provide insight into the development of the disorder in genetically-susceptible individuals.

    Dengue has been a major public health concern in Australia since it re-emerged in Queensland in 1992-1993. This study explored spatio-temporal distribution and clustering of locally-acquired dengue cases in Queensland State, Australia and identified target areas for effective interventions. A computerised locally-acquired dengue case dataset was collected from Queensland Health for Queensland from 1993 to 2012. Descriptive spatial and temporal analyses were conducted using geographic information system tools and geostatistical techniques. Dengue hot spots were detected using SatScan method. Descriptive spatial analysis showed that a total of 2,398 locally-acquired dengue cases were recorded in central and northern regions of tropical Queensland. A seasonal pattern was observed with most of the cases occurring in autumn. Spatial and temporal variation of dengue cases was observed in the geographic areas affected by dengue over time. Tropical areas are potential high-risk areas for mosquito-borne diseases such as dengue. This study demonstrated that the locally-acquired dengue cases have exhibited a spatial and temporal variation over the past twenty years in tropical Queensland, Australia. There is a clear evidence for the existence of statistically significant clusters of dengue and these clusters varied over time. These findings enabled us to detect and target dengue clusters suggesting that the use of geospatial information can assist the health authority in planning dengue control activities and it would allow for better design and implementation of dengue management programs.

    The {sup 40}Ar/{sup 39}Ar and U-Pb methods of isotopic dating have been used to determine the age of alteration minerals and host rocks from a number of Permo-Carboniferous Au deposits in the Tasman Fold Belt system of northeast Queensland. There was a continuum in porphyry-style Au mineralisation from ca 330 to 290 Ma, which post-dates epithermal Au in the Eastern Basin sequence of the Drummond Basin. Porphyry-style Au at Kidston. and the Buck Reef. Ravenswood, formed at ca 330 Ma. The Red Dome and Mungana skarns were deposited at ca 320-310 Ma and ca 310 Ma. respectively The Au mineralisation at Mt Wright. and in the quartz-sulfide veins. Ravenswood. was emplaced at ca 310-305 Ma. The youngest porphyry-style Au deposit is Mt Leyshon, which probably formed at ca 290 Ma Where high-level intrusions are associated with Au, magmatism and mineralisation are. in general. essentially coeval. The age of the host rocks to the Permo-Carboniferous Au deposits is variable, and may be more than 150 million years older than the mineralisation. The plutonic-style Au deposit at Charters Towers is significantly older than the porphyry systems, and formed at ca 414 Ma. Copyright (1998) Blackwell Science Asia 64 refs., 2 tabs., 14 figs.

    2016-12-01

    Mandatory bicycle helmet laws have been found to increase helmet wearing rates in Australia and internationally. However, much of the research on factors influencing compliance with the Australian helmet laws is dated or focuses on commuters and city areas only. To address this gap, video recordings of bicycle riders were undertaken at 17 sites across Queensland, Australia, representing a mixture of on- and off-road locations, speed limits and regions. Helmet status was able to be determined for 98% of riders observed. The level of compliance with the laws was very high, with 98.3% of the more than 27,000 riders observed wearing helmets. Riders riding on roads were less compliant than those riding on bicycle paths, but no significant differences were observed between the school-holiday and school-term periods. Among the on-road riders, boys were less compliant than girls and overall children were less compliant than adults. Higher compliance levels were found for group riders, road bike riders, lycra-clad riders, during morning hours, and on 50km/h or lower speed limit roads. While the overall level of compliance was very high, certain subgroups were identified as a possible focus for interventions to further improve the compliance level, for example children (particularly boys) riding mountain bikes away from groups during the afternoon hours on 60km/h roads.

    Park, Julie; Kantrow, Charles M.; Coulthard, Mark G.

    2016-01-01

    Background: The University of Queensland (UQ), Ochsner Clinical School (OCS) is a partnership between Ochsner Health System in New Orleans, LA, and UQ in Brisbane, Australia. OCS medical students are trained on both continents, receiving their didactic education in Australia and their clinical education in the United States. Methods: We review the OCS experience and compare the pediatric rotations at OCS and UQ. Results: Students in the pediatric rotations in Australia and in the United States receive their clinical instruction in the real-world learning environment of hospitals and clinics. In addition, lectures, online learning modules, case-based tutorials, and rigorous assessment at the end of the rotation help prepare medical students for future contact with pediatric patients. Sixty-nine third-year OCS students and 499 fourth-year UQ students completed the pediatric rotation in 2014. In 2015, 105 third-year OCS students and approximately 400 fourth-year UQ students completed the pediatric rotation. Conclusion: In a unique educational collaboration, OCS has used e-learning and face-to-face tutorials to produce a well-rounded curriculum that assimilates global healthcare and international medicine. This article demonstrates the feasibility of delivering a standardized curriculum across two continents using modern e-learning tools. PMID:27046407

    Full Text Available BACKGROUND: Mosquito-borne diseases are climate sensitive and there has been increasing concern over the impact of climate change on future disease risk. This paper projected the potential future risk of Barmah Forest virus (BFV disease under climate change scenarios in Queensland, Australia. METHODS/PRINCIPAL FINDINGS: We obtained data on notified BFV cases, climate (maximum and minimum temperature and rainfall, socio-economic and tidal conditions for current period 2000-2008 for coastal regions in Queensland. Grid-data on future climate projections for 2025, 2050 and 2100 were also obtained. Logistic regression models were built to forecast the otential risk of BFV disease distribution under existing climatic, socio-economic and tidal conditions. The model was applied to estimate the potential geographic distribution of BFV outbreaks under climate change scenarios. The predictive model had good model accuracy, sensitivity and specificity. Maps on potential risk of future BFV disease indicated that disease would vary significantly across coastal regions in Queensland by 2100 due to marked differences in future rainfall and temperature projections. CONCLUSIONS/SIGNIFICANCE: We conclude that the results of this study demonstrate that the future risk of BFV disease would vary across coastal regions in Queensland. These results may be helpful for public health decision making towards developing effective risk management strategies for BFV disease control and prevention programs in Queensland.

    To determine the impact of the introduction of universal access to ambulance services via the implementation of the Community Ambulance Cover (CAC) program in Queensland in 2003-04. The study involved a 10-year (2000-01 to 2009-10) retrospective analysis of routinely collected data reported by the Queensland Ambulance Service (QAS) and by the Council of Ambulance Authorities. The data were analysed for the impact of policy changes that resulted in universal access to ambulance services in Queensland. QAS is a statewide, publically funded ambulance service. In Queensland, ambulance utilisation rate (AUR) per 1000 persons grew by 41% over the decade or 3.9% per annum (10-year mean=149.8, 95% CI: 137.3-162.3). The AUR mean after CAC was significantly higher for urgent incidents than for non-urgent ones. However projection modelling demonstrates that URs after the introduction of CAC were significantly lower than the projected utilisation for the same period. The introduction of universal access under the Community Ambulance Cover program in Queensland has not had any significant independent long-term impact on demand overall. There has been a reduction in the long-term growth rate, which may have been contributed to by an 'appropriate use' public awareness program.

  13. Some thermoluminescence ages in Queensland: a problem resolved

    Energy Technology Data Exchange (ETDEWEB)

    Prescott, J.R. [Adelaide Univ., SA (Australia)

    1997-12-31

    In a previous paper (Tejan-Kella et al Aust J. Soil Res. 28, 465, 1990), thermoluminescence (TL) dates were presented for a soil horizon at five sites in a chronosequence of freely-drained podzols at Cooloola and North Stradbroke Island, Queensland. The TL ages followed the expected order based on geomorphological evidence; and the TL age of 120 {+-}11 ka for the Amity dune on North Stradbroke Island agreed with uranium series dates for underlying coral recovered during sand mining. Nevertheless, several features of the TL results gave rise to some concern and were noted in the above mentioned paper. Specifically, the apparent TL age of 11 {+-} 2 ka for the Kings Bore site was widely at variance with the inferred age of about 0.5 ka based on geomorphological and soil profile evidence. Further, an apparent TL age of about 8 ka was found for samples from the Carlo sand blow. The Carlo samples were taken at mean depths of 1.0 m and 1.5 m from within the advancing toe of the dune, which is obviously mobile since it is encroaching on living vegetation. The time since last exposure to sunlight could scarcely exceed a decade. New measurements are reported, designed to resolve the former discrepancies. All sites have been re-dated, together with a new one, CA5S/1 (Chalambar) and a reduced value have been obtained. The fact that the TL age is somehow smaller than the U-series age may reflect the expectation that the summit of the dune be younger than the base. Paper no. 14; 1 tab., 1 fig.

    Alluvial terraces provide a record of aggradation and incision and are studied to understand river response to changes in climate, tectonic activity, sea level, and factors internal to the river system. Terraces form in all climatic regions and in a range of geomorphic settings; however, relatively few studies have been undertaken in tectonically stable settings in the tropics. The preservation of alluvial terraces in a valley is driven by lateral channel adjustments, vertical incision, aggradation, and channel stability, processes that can be further understood through examining catchment force-resistance frameworks. This study maps and classifies terraces using soil type, surface elevation, sedimentology, and optically stimulated luminescence dating across five tropical catchments in northeast Queensland, Australia. This allowed for the identification of two terraces across the study catchments (T1, T2). The T1 terrace was abandoned ~ 13.9 ka with its subsequent removal occurring until ~ 7.4 ka. Abandonment of the T2 terrace occurred ~ 4.9 ka with removal occurring until ~ 1.2 ka. Differences in the spatial preservation of these terraces were described using an index of terrace preservation (TPI). Assessments of terrace remnant configuration highlighted three main types of terraces: paired, unpaired, and disconnected, indicating the importance of different processes driving preservation. Regional-scale variability in TPI was not strongly correlated with catchment-scale surrogate variables for drivers of terrace erosion and resistance. However, catchment-specific relationships between TPI and erosion-resistance variables were evident and are used here to explain the dominant processes driving preservation in these tropical settings. This study provides an important insight into terrace preservation in the tectonically stable, humid tropics and provides a framework for future research linking the timing of fluvial response to palaeoclimate change.

    The extraction of coal seam gas (CSG) produces large volumes of potentially contaminated water. It has raised concerns about the environmental health impacts of the co-produced CSG water. In this paper, we review CSG water contaminants and their potential health effects in the context of exposure pathways in Queensland's CSG basins. The hazardous substances associated with CSG water in Queensland include fluoride, boron, lead and benzene. The exposure pathways for CSG water are (1) water used for municipal purposes; (2) recreational water activities in rivers; (3) occupational exposures; (4) water extracted from contaminated aquifers; and (5) indirect exposure through the food chain. We recommend mapping of exposure pathways into communities in CSG regions to determine the potentially exposed populations in Queensland. Future efforts to monitor chemicals of concern and consolidate them into a central database will build the necessary capability to undertake a much needed environmental health impact assessment.

    Streptococcus pneumoniae serotype 6C was first identified in 2007, although retrospective studies have since identified serotype 6C among stored isolates dating back to 1962. We investigated the incidence and genetic diversity of serotype 6C strains isolated from Queensland patients between 2001 and 2011. Isolates were identified by Quellung reaction and antimicrobial susceptibility testing was performed. The incidence of serotype 6C among serogroup 6 Queensland invasive pneumococcal disease increased from 6.8% (2001-2004) to 39% (2005-2010) of serogroup 6 isolates (P = 0). Genetic diversity of Queensland 6C isolates was high, with molecular analysis identifying 19 sequence types by multi-locus sequence typing, and 35 types by multi-locus variable-number tandem repeat analysis.

    2012-01-01

    Queensland Mining has a strong focus on safety performance, but risk management of health, including Musculoskeletal Disorders (MSDs) continues to have a lower priority. The reliance on individual screening of workers and lower level approaches such as manual handling training is part of the coal mining 'culture'. Initiatives such as the New South Wales and Queensland Mining joint project to develop good practice guidance for mining has allowed for a more consistent message on participatory ergonomics and prevention of MSD. An evidence based practice approach, including the introduction of participatory ergonomics and safe design principles, was proposed to Anglo American Coal operations in Queensland. The project consisted of a skills analysis of current health personnel, design of a facilitated participatory ergonomics training program, site visits to identify good practice and champions, and a graduated mentoring program for health personnel. Early results demonstrate a number of sites are benefiting from site taskforces with a focus on positive performance outcomes.

    Bellairs, S.M. [University of Queensland, St Lucia, Qld. (Australia). Dept. of Agriculture and Centre for Mined Land Rehabilitation

    1997-06-01

    This paper provides an overview of research carried out on soil seed banks in relation to minesite rehabilitation in Queensland. Quantitative studies of the soil bank have been carried out at several sites including: prior to mineral sand mining on North Stradbroke Island, the Blair Athol, Curragh and Newlands open-cut coal mines in central Queensland, and the Tarong Coal mine in southeast Queensland. The size of the germinable seed bank in the surface few centimetres of topsoil ranged considerably, from less than 20 to greater than 2,000 seeds per square metre. There was as much variation between different vegetation types at the same minesite as between sites. Where the seed bank was large, it tended to consist of grasses or other monocotyledons, and fewer seeds were present in communities with more substantial tree and shrub strata. The contribution of the soil seed bank relative to the broadcast seed mix is also discussed. 22 refs., 3 tabs.

    1994-08-01

    Stereological procedures were used to estimate the amount of amyloid deposition in the pancreatic islets of 83 cats from random sources in south-eastern Queensland. Most had only minor deposits of less than 20% of islet volume (median 9%), but deposits equal to more than 50% of the islet volume were found in 10% of the cats. Amyloid deposition in pancreatic islets was correlated with the age of the cat. Although similar observations have been made previously in cats from the USA, the frequency of amyloid deposition was higher in this population of cats from south-eastern Queensland.

    2006-12-01

    Ultraviolet radiation (UV) has the possibility to both harm and to benefit human beings when unprotected exposure occurs. After receiving small amounts of UV our bodies begin to synthesise vitamin D, which is essential for maintaining healthy bones, however excessive UV exposure can result in a variety of damaging outcomes ranging from sunburn to skin cancer and cataracts. For this reason it is very important to understand the different environments in which people encounter UV so as to better prepare the public to make smart and healthy sun exposure decisions. Each day more and more people are moving into large cities around the world and spending their time inside the urban canyon, however UV measurements are generally taken at scientific stations in open areas or on top of tall buildings, meaning that at times the environmental characteristics measured may not accurately represent those found at street-level in these highly urbanized areas. Urban canyons are home to both very tall buildings and tropospheric air pollution, each of which reduces the amount of UV reaching street-level. This study measured the varying difference between UV measurements taken at street-level and at a standard UV monitoring site on top of a building outside of the urban canyon. Investigation was conducted in the central business district (CBD) of Brisbane, Australia, which models the CBDs of large cities around the world in that it boasts a great number of tall buildings, including many skyscrapers. Data was collected under clear sky conditions at five different street-level sites in the CBD (on either side of two streets running perpendicular to one another (four sites) and in a public square) and then compared to that obtained on the same day at the Queensland University of Technology's Australian Sun and Health Research Laboratory (ASHRL), which is located 2.5 kilometres outside Brisbane's CBD. Minimum erythemal dose (MED) data was collected at each location and it was found that

    Plagens, Owen; Castillo, Martin; Steinberg, Theodore; Ong, Teng-Cheong

    The Queensland University of Technology (QUT) Drop Tower Facility is a {raise.17exscriptstyle˜}2.1 second, 21.3 m fall, dual capsule drop tower system. The dual capsule comprises of an uncoupled exterior hollow drag shield that experiences drag by the ambient atmosphere with the experimental capsule falling within the drag shield. The dual capsule system is lifted to the top of the drop tower via a mechanical crane and the dropping process is initiated by the cutting of a wire coupling the experimental package and suspending the drag shield. The internal experimental capsule reaches the bottom of the drag shield floor just prior to the deceleration stage at the air bag and during this time experience gravity levels of {raise.17exscriptstyle˜}10textsuperscript{-6} g. The deceleration system utilizes an inflatable airbag where experimental packages can be designed to experience a maximum deceleration of {raise.17exscriptstyle˜}10textsuperscript{18} g for {raise.17exscriptstyle˜}0.1 seconds. The drag shield can house experimental packages with a maximum diameter of 0.8 m and height of 0.9 m. The drag shield can also be used in foam mode, where the walls are lined with foam and small experiments can be dropped completely untethered. This mode is generally used for the study of microsatellite manipulation. Payloads can be powered by on-board power systems with power delivered to the experiment until free fall occurs. Experimental data that can be collected includes but is not limited to video, temperature, pressure, voltage/current from the power supply, and triggering mechanisms outputs which are simultaneously collected via data logging systems and high speed video recording systems. Academic and commercial projects are currently under investigation at the QUT Drop Tower Facility and collaboration is openly welcome at this facility. Current research includes the study of heterogeneously burning metals in oxygen which is aimed at fire safety applications and

    Understanding how socioecological factors affect the transmission of dengue fever (DF) may help to develop an early warning system of DF. We examined the impact of socioecological factors on the transmission of DF and assessed potential predictors of locally acquired and overseas-acquired cases of DF in Queensland, Australia. We obtained data from Queensland Health on the numbers of notified DF cases by local government area (LGA) in Queensland for the period 1 January 2002 through 31 December 2005. Data on weather and the socioeconomic index were obtained from the Australian Bureau of Meteorology and the Australian Bureau of Statistics, respectively. A Bayesian spatial conditional autoregressive model was fitted at the LGA level to quantify the relationship between DF and socioecological factors. Our estimates suggest an increase in locally acquired DF of 6% [95% credible interval (CI): 2%, 11%] and 61% (95% CI: 2%, 241%) in association with a 1-mm increase in average monthly rainfall and a 1°C increase in average monthly maximum temperature between 2002 and 2005, respectively. By contrast, overseas-acquired DF cases increased by 1% (95% CI: 0%, 3%) and by 1% (95% CI: 0%, 2%) in association with a 1-mm increase in average monthly rainfall and a 1-unit increase in average socioeconomic index, respectively. Socioecological factors appear to influence the transmission of DF in Queensland, but the drivers of locally acquired and overseas-acquired DF may differ. DF risk is spatially clustered with different patterns for locally acquired and overseas-acquired cases.

    'New legislation in Queensland has provided a "pathway" for the privatisation of health assets and services in Queensland, which effectively realigns the health care system to the financial market. This column explores how this legislation contained the antecedents of the Queensland doctors' dispute when doctors roundly rejected new employment contracts in February 2014. It also argues that such legislation and its attendant backlash provides a valuable case study in view of the federal government's 2014 budget offer to the States of extra funding if they sell their health assets to fund new infrastructure. The move to privatise health in Queensland has also resulted in a government assault on the ethical credibility of the opposing medical profession and changes to the health complaints system with the introduction of a Health Ombudsman under ministerial control. The column examines these changes in light of R (Heather) v Leonard Cheshire Foundation [2001] EWHC Admin 429, a case concerning the obligations of a private entity towards publically funded clients in the United Kingdom. In discussing concerns about the impact of privatisation on the medical profession, the column points to a stark conflict between the duty to operate hospitals as a business rather than as a duty to patients.

  19. Journey to the centre of the earth: coal seam gas in Queensland

    Energy Technology Data Exchange (ETDEWEB)

    Dighton, P.

    1998-12-31

    Coal Seam Gas (CSG) is potentially an important energy source of the future. In addition to being a valuable energy source, the utilisation of CSG will also decrease significantly the adverse greenhouse effects of venting CSG to the atmosphere. Although CSG is presently being recovered and utilised in both Queensland and New South Wales, its economic viability at the moment is marginal. However technological advances or fiscal incentives could see this change rapidly. At present most of the Queensland coal fields have overlapping petroleum tenures. While this has not presented significant conflicts to date, holders of Authorities To Prospect are automatically entitled to production leases from discovery of petroleum, including coal seam gas, deposits. The Queensland government has addressed this potential conflict by producing a `final position` paper. One of the main proposals is to protect the coal mining industry by the declaration of CSG areas and strata titling of the relevant interests. The legislation, presently being drafted for submission to the new Queensland Parliament, is outlined.

    2015-01-01

    Full Text Available In-water monitoring of marine vertebrates is usually expensive while the use of stranding data can be used to provide a cost-effective estimation of disease and mortality. Strandings for Queensland are recorded in a web based database (StrandNet managed by the Queensland Government’s Department of Environment and Heritage Protection (EHP. Data recorded in StrandNet from the east coast of Queensland between 1996 and 2013 were investigated for patterns of stranding. Significant trends in Queensland over this time were (i an increase in the number of animals reported stranded within this study site; (ii a species (loggerhead and green marine turtles prevalence; (iii a seasonal effect on different age classes stranding with most overall strandings occurring between August and November; and (iv stranding hotspots (Moreton Bay, Hervey Bay, Rockhampton region, and Cleveland Bays persisting throughout the study timeframe. This study suggested that intervention strategies, such as rehabilitation, should be able to be focussed on periods of heightened importance and specific localities to minimize health risks and contribute to sustainable use of resources.

  3. Assumptions and advice: mothers and Queensland well-baby clinics. A review.

    Science.gov (United States)

    Thorley, Virginia

    2014-03-01

    In 20th century Australia, free well-baby clinics were run by maternal and child health nurses, although the funding and organisational structure varied from state to state. It was assumed that women who attended followed the advice assiduously; yet attendance did not necessarily equate to practice. In Queensland, the state government's free Maternal and Child Welfare Service (MCW) advised mothers on infant feeding and care through well-baby clinics throughout the state, a correspondence section for mothers in remote areas and a railcar clinic to some western towns, under the state government's policy of covering every mother and baby in Queensland. Women in Queensland, as in other states, were exposed to other influences on how to feed babies and often exercised agency in making their own decisions according to their circumstances and their own judgment. This review will place research from Queensland on women's reasons for attending the clinics and adherence to the advice provided, during the period 1920-1965, within a wider context. This includes research on barriers to following advice, counselling versus imparting information and the mother's self-efficacy. The message for today is that adherence to advice still cannot be assumed and mothers' own circumstances need to be factored in.

    1999-02-01

    To analyze archival physiotherapy records at a major military base in North Queensland, Australia, to investigate the epidemiology of injuries associated with sports and training, examining for possible risk factors for military training injury. A retrospective study was undertaken during a 62-month period, from 1987 to 1992, at Lavarack Barracks, Townsville, Australia, which services a dynamic population base of some 5,000 uniformed staff. Sociodemographic basic data, as well as treatment-related data (treatment area, number and type, interval between onset and initial treatment, reported cause), were used. Admission records were recoded according to the Orchard Sports Injury Classification System (version 2.0) standard. During the 62-month period from 1987 to 1992, 4,993 personnel, 96.2% (4,803/4,993) males and 3.7% (190/4,993) females, were referred for 5,025 physiotherapy treatments. The incidence of injuries requiring physiotherapy was 80.4 new patients per 5,000 personnel per month, and the incidence rate of injury was 19.3% per year or 0.19 injuries per person per year. The mean age of patients was 25.7 +/- 6.2 (SD) years, and the median age was 24 years, with a range of 17 to 59 years. Injuries were related to military training (29.3%, 1,471/5,025), diverse causes (21.2%, 1,072/5,025), sports (13.8%, 694/5,025), insidious onset (11.8%, 589/5,025), football (11.7%, 586/5,025), manual handling (4.2%, 211/5,025), motor vehicle crashes (4.1%, 206/5,025), and surgery (3.9%, 196/5,025). The four major body areas treated by physiotherapists were the knee joint (37.0%, 1,321/3,612), lumbar spine (29.8%, 1,075/3,612), ankle (19.9%, 719/3,612), and shoulder joints (13.8%, 497/3,612), which accounted for nearly three-quarters of all admissions. Of these, most were referred without definitive diagnosis (71.1%, 2,572/3,612), with the remainder comprising joint injuries (17.5%, 634/3,612), other types of pathology such as chest infections or neurological involvement

    The koala (Phascolarctos cinereus) suffered population declines and local extirpation due to hunting in the early 20th century, especially in southern Australia. Koalas were subsequently reintroduced to the Brisbane Ranges (BR) and Stony Rises (SR) by translocating individuals from a population on French Island descended from a small number of founders. To examine genetic diversity and north-south differentiation, we genotyped 13 microsatellite markers in 46 wild koalas from the BR and SR, and 27 Queensland koalas kept at the US zoos. The Queensland koalas displayed much higher heterozygosity (H O = 0.73) than the 2 southern Australian koala populations examined: H O = 0.49 in the BR, whereas H O = 0.41 in the SR. This is consistent with the historical accounts of bottlenecks and founder events affecting the southern populations and contrasts with reports of high genetic diversity in some southern populations. The 2 southern Australian koala populations were genetically similar (F ST = 0.018, P = 0.052). By contrast, northern and southern Australian koalas were highly differentiated (F ST = 0.27, P koalas. Sequencing of 648bp of the mtDNA control region in Queensland koalas found 8 distinct haplotypes, one of which had not been previously detected among koalas. Queensland koalas displayed high mitochondrial haplotype diversity (H = 0.753) and nucleotide diversity (π = 0.0072), indicating along with the microsatellite data that North American zoos have maintained high levels of genetic diversity among their Queensland koalas. © The American Genetic Association 2016.

    Objective To determine trends in the incidence of foot-related hospitalisation and amputation amongst persons with diabetes in Queensland (Australia) between 2005 and 2010 that coincided with changes in state-wide ambulatory diabetic foot-related complication management. Methods All data from cases admitted for the principal reason of diabetes foot-related hospitalisation or amputation in Queensland from 2005–2010 were obtained from the Queensland Hospital Admitted Patient Data Collection dataset. Incidence rates for foot-related hospitalisation (admissions, bed days used) and amputation (total, minor, major) cases amongst persons with diabetes were calculated per 1,000 person-years with diabetes (diabetes population) and per 100,000 person-years (general population). Age-sex standardised incidence and age-sex adjusted Poisson regression models were also calculated for the general population. Results There were 4,443 amputations, 24,917 hospital admissions and 260,085 bed days used for diabetes foot-related complications in Queensland. Incidence per 1,000 person-years with diabetes decreased from 2005 to 2010: 43.0% for hospital admissions (36.6 to 20.9), 40.1% bed days (391 to 234), 40.0% total amputations (6.47 to 3.88), 45.0% major amputations (2.18 to 1.20), 37.5% minor amputations (4.29 to 2.68) (p amputations (18.57 to 14.99), 26.4% major amputations (6.26 to 4.61), 15.7% minor amputations (12.32 to 10.38) (p amputations 0.962 (0.946–0.979), major amputations 0.945 (0.917–0.974), minor amputations 0.970 (0.950–0.991) (p amputation amongst persons with diabetes in the population of Queensland over a recent six-year period.

    Ross River virus (RRV) infection is a debilitating disease that has a significant impact on population health, economic productivity, and tourism in Australia. This study examined epidemiologic patterns of RRV disease in Queensland, Australia, during January 2001–December 2011 at a statistical local area level. Spatio-temporal analyses were used to identify the patterns of the disease distribution over time stratified by age, sex, and space. The results show that the mean annual incidence was 54 per 100,000 persons, with a male:female ratio of 1:1.1. Two space-time clusters were identified: the areas adjacent to Townsville, on the eastern coast of Queensland, and the southeast areas. Thus, although public health intervention should be considered across all areas in which RRV occurs, it should specifically focus on high-risk regions, particularly during summer and autumn to reduce the social and economic impacts of RRV infection.

    A review of insects collected from decomposing human remains in south-east Queensland yielded 32 species in three orders (Diptera, Coleoptera, Hymenoptera) and 11 families (Calliphoridae, Sarcophagidae, Muscidae, Phoridae, Sepsidae, Chironomidae, Dermestidae, Cleridae, Histeridae, Staphylinidae, Encyrtidae). There were 15 cases where remains were located indoors and five cases where remains were outdoors, in both terrestrial and aquatic environments. Coleoptera were strongly associated with outdoors remains, while dipteran species composition was similar in both indoor and outdoor habitats. Some Diptera were only associated with indoors remains, while others were similarly restricted to remains recovered outdoors. Hymenopteran parasitoids were active in both habitats. Comparative collections were made from other vertebrate remains, including road-kill and farmed animals throughout south-east Queensland (Qld) and northern New South Wales (NSW) during the same period.

    Conclusions: Although many people throughout QLD have heard of dengue, about 15% appear unaware of local transmission, its symptoms and of methods to reduce risk of infection. A lack of knowledge regarding prevention of mosquito breeding is evident in South East QLD, where dengue is not currently reported. The study suggests that future dengue awareness campaigns should target communities in both endemic and potentially endemic areas throughout Queensland.

    It remains unclear over whether it is possible to develop an epidemic forecasting model for transmission of dengue fever in Queensland, Australia. To examine the potential impact of El Niño/Southern Oscillation on the transmission of dengue fever in Queensland, Australia and explore the possibility of developing a forecast model of dengue fever. Data on the Southern Oscillation Index (SOI), an indicator of El Niño/Southern Oscillation activity, were obtained from the Australian Bureau of Meteorology. Numbers of dengue fever cases notified and the numbers of postcode areas with dengue fever cases between January 1993 and December 2005 were obtained from the Queensland Health and relevant population data were obtained from the Australia Bureau of Statistics. A multivariate Seasonal Auto-regressive Integrated Moving Average model was developed and validated by dividing the data file into two datasets: the data from January 1993 to December 2003 were used to construct a model and those from January 2004 to December 2005 were used to validate it. A decrease in the average SOI (ie, warmer conditions) during the preceding 3-12 months was significantly associated with an increase in the monthly numbers of postcode areas with dengue fever cases (beta=-0.038; p = 0.019). Predicted values from the Seasonal Auto-regressive Integrated Moving Average model were consistent with the observed values in the validation dataset (root-mean-square percentage error: 1.93%). Climate variability is directly and/or indirectly associated with dengue transmission and the development of an SOI-based epidemic forecasting system is possible for dengue fever in Queensland, Australia.

    Full Text Available BACKGROUND: Barmah Forest virus (BFV disease is a common and wide-spread mosquito-borne disease in Australia. This study investigated the spatio-temporal patterns of BFV disease in Queensland, Australia using geographical information system (GIS tools and geostatistical analysis. METHODS/PRINCIPAL FINDINGS: We calculated the incidence rates and standardised incidence rates of BFV disease. Moran's I statistic was used to assess the spatial autocorrelation of BFV incidences. Spatial dynamics of BFV disease was examined using semi-variogram analysis. Interpolation techniques were applied to visualise and display the spatial distribution of BFV disease in statistical local areas (SLAs throughout Queensland. Mapping of BFV disease by SLAs reveals the presence of substantial spatio-temporal variation over time. Statistically significant differences in BFV incidence rates were identified among age groups (χ(2 = 7587, df = 7327,p<0.01. There was a significant positive spatial autocorrelation of BFV incidence for all four periods, with the Moran's I statistic ranging from 0.1506 to 0.2901 (p<0.01. Semi-variogram analysis and smoothed maps created from interpolation techniques indicate that the pattern of spatial autocorrelation was not homogeneous across the state. CONCLUSIONS/SIGNIFICANCE: This is the first study to examine spatial and temporal variation in the incidence rates of BFV disease across Queensland using GIS and geostatistics. The BFV transmission varied with age and gender, which may be due to exposure rates or behavioural risk factors. There are differences in the spatio-temporal patterns of BFV disease which may be related to local socio-ecological and environmental factors. These research findings may have implications in the BFV disease control and prevention programs in Queensland.

  17. Aboriginal ‘resistance war’ tactics – ‘The Black War’ of southern Queensland

    Directory of Open Access Journals (Sweden)

    Raymond Constant Kerkhove

    2015-02-01

    Full Text Available Frontier violence is now an accepted chapter of Australian history.  Indigenous resistance is central to this story, yet little examined as a military phenomenon (Connor 2004.  Indigenous military tactics and objectives are more often assumed than analysed. Building on Laurie’s and Cilento’s contentions (1959 that an alliance of Aboriginal groups staged a ‘Black War’ across southern Queensland between the 1840s and 1860s, the author seeks evidence for a historically definable conflict during this period, complete with a declaration, coordination, leadership, planning and a broader objective: usurping the pastoral industry.   As the Australian situation continues to present elements which have proved difficult to reconcile with existing paradigms for military history, this study applies definitions from guerilla and terrorist conflict (e.g. Eckley 2001, Kilcullen 2009 to explain key features of the southern Queensland “Black War.” The author concludes that Indigenous resistance, to judge from southern Queensland, followed its own distinctive pattern.  It achieved coordinated response through inter-tribal gatherings and sophisticated signaling.  It relied on economic sabotage, targeted payback killings and harassment.  It was guided by reticent “loner-leaders.” Contrary to the claims of military historians such as Dennis (1995, the author finds evidence for tactical innovation.  He notes a move away from pitched battles to ambush affrays; the development of full-time ‘guerilla bands’; and use of new materials.

    Outbreaks of dengue occur in Queensland, Australia nearly every summer. In 2008-2009, there was an unusually large, protracted outbreak of dengue, comprised of 1,200 cases. We investigated the weather variables and their contribution to the 2008-2009 dengue outbreak in Queensland. Case data were obtained from the Communicable Disease Branch of Queensland Health for 2000-2010 for the towns of Cairns and Townsville. Monthly weather data (rainfall, maximum temperature, minimum temperature) and Southern Oscillation Index (SOI) was obtained from the Bureau of Meteorology (BOM). We used a negative binomial model to test associations between these variables and dengue. Lagged models were also created for one, two and three months. Our models suggest all weather variables but not the SOI were associated with dengue in both Cairns and Townsville, without a lag (pRainfall and temperature preceding the 2008-2009 outbreak were also not significantly different (p<0.01) from other years. Short-term (non-lagged) weather variables were associated with the number of dengue cases in Cairns and Townsville. No lag was seen and no association was seen between the SOI and the number of dengue cases, which suggests there may be limited potential to predict large dengue outbreaks using climate variability. The large outbreak in 2008-2009 may have been driven by other, non-weather factors in addition to the immediate weather effect.

    Zika virus could be transmitted in the state of Queensland, Australia, in parts of the state where the mosquito vectors are established. We assessed the epidemic potential of Zika in Queensland from January 2015 to August 2016, and estimate the epidemic potential from September to December 2016, by calculating the temperature-dependent relative vectorial capacity (rVc), based on empirical and estimated parameters. Through 2015, we estimated a rVc of 0.119, 0.152, 0.170, and 0.175, respectively in the major cities of Brisbane, Rockhampton, Cairns, and Townsville. From January to August 2016, the epidemic potential trend was similar to 2015, however the highest epidemic potential was in Cairns. During September to November 2016, the epidemic potential is consistently the highest in Cairns, followed by Townsville, Rockhampton and Brisbane. Then, from November to December 2016, Townsville has the highest estimated epidemic potential. We demonstrate using a vectorial capacity model that ZIKV could have been locally transmitted in Queensland, Australia during 2015 and 2016. ZIKV remains a threat to Australia for the upcoming summer, during the Brazilian Carnival season, when the abundance of vectors is relatively high. Understanding the epidemic potential of local ZIKV transmission will allow better management of threats to blood safety and assessment of public health risk.

  2. Analysis of Bordetella pertussis pertactin and pertussis toxin types from Queensland, Australia, 1999–2003

    Slack Andrew T

    2006-03-01

    Full Text Available Abstract Background In Australia two acellular Bordetella pertussis vaccines have replaced the use of a whole cell vaccine. Both of the licensed acellular vaccines contain the following three components; pertussis toxoid, pertussis filamentous haemagglutinin and the 69 kDa pertactin adhesin. One vaccine also contains pertussis fimbriae 2 and 3. Various researchers have postulated that herd immunity due to high levels of pertussis vaccination might be influencing the makeup of endemic B. pertussis populations by selective pressure for strains possessing variants of these genes, in particular the pertactin gene type. Some publications have suggested that B. pertussis variants may be contributing to a reduced efficacy of the existing vaccines and a concomitant re-emergence of pertussis within vaccinated populations. This study was conducted to survey the pertactin and pertussis toxin subunit 1 types from B. pertussis isolates in Queensland, Australia following the introduction of acellular vaccines. Methods Forty-six B. pertussis isolates recovered from Queensland patients between 1999 and 2003 were examined by both DNA sequencing and LightCycler™ real time PCR to determine their pertactin and pertussis toxin subunit 1 genotypes. Results Pertactin typing showed that 38 isolates possessed the prn1 allele, 3 possessed the prn2 allele and 5 possessed the prn3 allele. All forty-six isolates possessed the pertussis toxin ptxS1A genotype. Amongst the circulating B. pertussis population in Queensland, 82.5% of the recovered clinical isolates therefore possessed the prn1/ptxS1A genotype. Conclusion The results of this study compared to historical research on Queensland isolates suggest that B. pertussis pertactin and pertussis toxin variants are not becoming more prevalent in Queensland since the introduction of the acellular vaccines. Current prevalences of pertactin variants are significantly different to that described in a number of other countries

    Leptospirosis is an emerging infectious disease, with increasing frequency and severity of outbreaks, changing epidemiology of populations at risk, and the emergence of new serovars. Environmental drivers of disease transmission include flooding, urbanisation, poor sanitation, changes in land use and agricultural practices, and socioeconomic factors. In Queensland, human infection with Leptosira borgpetersenii serovar Arborea was first reported in 2001. This study aims to report the emergence of serovar Arborea in Queensland from 2001 to 2013, and investigate potential risk factors for infection and drivers of emergence. Data on laboratory-confirmed cases of human leptospirosis in Queensland were obtained from the enhanced surveillance system at the WHO/FAO/OIE Collaborating Centre for Reference and Research on Leptospirosis in Brisbane, Australia. The changing epidemiology of serovar Arborea from 2001 to 2003 was described with respect to case numbers, proportion of leptospirosis cases attributed to the serovar, and geographic distribution. Differences in risk factors for the most common serovars were compared. During this period, 1289 cases of leptospirosis were reported, including 233 cases attributed to serovar Arborea. Risk factors for infection include male gender (91 % of cases), occupation, and recreational exposure. Most common occupations recorded were banana workers (28.4 %), meat workers (7.2 %), dairy farmers (5.8 %), graziers/stockmen (5.5 %), 'other agricultural/rural workers' (16.4 %), and tourists or tourism operators (4.6 %). Time trend analysis showed that while non-Arborea cases decreased over the study period, Arborea cases increased by 3.4 cases per year. The proportion of annual cases attributed to Arborea peaked at 49 % in 2011 after unprecedented flooding in Queensland. Mapping of cases by residential location showed expansion of the geographic range of serovar Arborea, concentrating mostly around Brisbane, Cairns and Innisfail. Serovars

It shows how this methodology supports the family-centered care philosophy of the organization and gives staff insight into the experience of the families they care for. In total, 17 Discovery Interviews recorded during 2012–2014 were transcribed, deidentified, condensed, and read back to 222 staff in 20 different meetings. Families and staff involved in the process provided positive feedback. Over 53% of staff found these sessions extremely valuable, and 46% rated them as valuable. Discovery Interviews were shown to be a powerful tool to engage with families and staff to improve the experience of families in the Queensland Children's Cancer Centre. The sessions where Discovery Interviews were read to clinical teams raised their awareness of the perspectives of families and impacted on the way they delivered care and interacted with families. Staff described the stories as insightful and valued hearing them and discussing ways to improve service, including individual clinical practice, service processes, and family supports.

    This study aims to ascertain if differences exist in the perception of the professional practice environment and personal well-being of nurses across different geographical areas in Queensland. This paper was performed on a prospective, self-report cross-sectional on-line survey. The study was conducted among the nurses employed in public and private health care settings: acute hospitals, community health and aged care in Queensland, Australia. Participants of this study were 1608 registered and enrolled nurses and assistants in nursing, current members of the Queensland Nurses Union in 2013 and who provided a workplace postcode. One thousand eight of these participants worked in major cities, while 382 in rural locations and 238 in remote areas. None. Scores of well-being as determined by the following scales: the Depression, Anxiety and Stress Scale, the Professional Quality of Life Scale version 5, the Connor-Davidson Resilience Scale and of the Professional Practice Environment using the Practice Environment Scale - Nursing Work Index Revised. Nurses employed in major cities perceived 'nursing foundations for quality care' more favourably than those from other settings. Remote area nurses had lower levels of secondary traumatic stress than nurses in major cities and rural areas. There was no difference between nurses across their geographical locations for stress, anxiety, depression, compassion satisfaction, burnout, resilience and the four other measures of the Practice Environment Scale. The study findings provide new data suggesting that, with the exception of secondary traumatic stress, the personal well-being of nurses does not differ across geographical settings. Similarly, with the exception of the subscale of 'nursing foundations for quality care' there was no difference in perceptions of the professional practice environment. As secondary traumatic stress is associated with burnout, this finding needs to be investigated further. © 2015 National Rural

    To review management of ductal carcinoma in situ (DCIS) of the breast in Queensland, with reference to breast conserving surgery (BCS) and adjuvant radiation therapy (RT). In addition, we examined the incidence of invasive breast cancer recurrence and factors predictive of invasive recurrence. A retrospective review of the Queensland Oncology Repository identified women with resected DCIS (TisN0) ± adjuvant RT between 2003 and 2012. Time to invasive breast cancer recurrence was analysed using the Kaplan Meier method. Median follow-up was 4.9 years. 3038 women had surgery. 940 (31%) had mastectomy and 2098 (69%) underwent BCS. Of 2098 women having BCS, 1100 (52%) received BCS alone and 998(48%) received adjuvant RT. The use of RT significantly increased over the decade from 25% to 62% (p=<0.001). Clinicopathological factors associated with RT use on multivariate analysis included age ≤70, higher socioeconomic status, larger tumour size, higher nuclear grade and surgical margins ≤5 mm. Invasive breast cancer recurrence at 5 years was 1.7% [95% CI 1.0-3.0] in RT group versus 2.8% [95% CI 2.1-3.8] in BCS alone group. Factors associated with increased risk of invasive recurrence on multivariate analysis were age <40 and surgical margins ≤2 mm. The use of adjuvant RT in Queensland significantly increased between 2003 and 2012. Selection of patients for RT was based on clinicopathological factors associated with higher recurrence risk. Although longer follow-up is required, the selective use of radiation therapy after BCS is associated with a low rate of invasive breast cancer recurrence at 5 years. Crown Copyright © 2017.

    The cotton tipworm, Crocidosema plebejana (Zeller), has periodically caused serious damage to seedling cotton in Southeast Queensland. An analysis of data over 11 years revealed that outbreaks of this pest are weather related. A heat/precipitation ratio (weather index) was calculated and compared with population levels of the tipworm. Outbreaks were strongly correlated to cool and wet weather during March--November, the principal growth period of the weed host Malva parviflora (L.). Infestations were minor when conditions were dry. A prediction based on this index is compared with field infestation levels in 1984. 16 refs., 1 fig., 6 tabs.

    Much of southern and eastern Australia including Queensland have experienced rainfall declines over recent decades affecting agricultural production and accelerating water infrastructure development. Rainfall declines from southern Australia have now been directly related to changes in the Southern Annular Mode (SAM) and the subtropical ridge. In southern and coastal Queensland, the rainfall declines have occurred mostly in the austral summer and autumn. Observations from this region reveal the rainfall decline is correlated to an increase in the mean sea level pressure (MSLP) at many stations. The largest increases in MSLP are over southeast Queensland and coastal regions, where some of the largest rainfall declines occur. This study indicates the subtropical ridge as one of the main factors in the rainfall decline over this region. SAM is also likely to be important, although its seasonal influence, apart from winter, is harder to determine.

    Bicycle injuries, particularly those resulting from single bicycle crashes, are underreported in both police and hospital records. Data on cyclist characteristics and crash circumstances are also often lacking. As a result, the ability to develop comprehensive injury prevention policies is hampered. The aim of this study was to examine the incidence, severity, cyclist characteristics, and crash circumstances associated with cycling injuries in a sample of cyclists in Queensland, Australia. A cross-sectional study of Queensland cyclists was conducted in 2009. Respondents (n=2056) completed an online survey about their cycling experiences, including cycling injuries. Logistic regression modelling was used to examine the associations between demographic and cycling behaviour variables with experiencing cycling injuries in the past year, and, separately, with serious cycling injuries requiring a trip to a hospital. Twenty-seven percent of respondents (n=545) reported injuries, and 6% (n=114) reported serious injuries. In multivariable modelling, reporting an injury was more likely for respondents who had cycled injuries. Copyright © 2011 Elsevier Ltd. All rights reserved.

    The effects of breeding season (late spring to early autumn) on south-east Queensland male koala fertility were examined to improve the efficacy of the AI procedure and to determine the practicality of using free-range animals as semen donors for a genome resource bank. Seasonal changes in male koala reproductive function were assessed in a wild free-range population (n = 14; obtained every 6 weeks from January to November 2005), a necropsied healthy wild population (n = 84; obtained monthly from September 2004 to August 2005) and a captive population (n = 7; obtained monthly from October 2005 to October 2006). Reproductive parameters investigated included bodyweight, coat score, sternal gland area and activity, testosterone secretion, reproductive anatomy volume and semen quality (before and after cryopreservation). Collectively, these findings show that reproduction in male koalas from south-east Queensland changes seasonally and that winter appears to be the optimal season in which to collect semen samples by electroejaculation. While it was possible to repeatedly collect semen from free-range koalas for future genetic management via potential storage in a genome resource bank, the survival of these spermatozoa after cryopreservation was poor and will require further improvement.

    The study aimed to investigate factors associated with work engagement and burnout in cancer workers in Queensland. A cross-sectional survey of 579 cancer workers in Queensland was undertaken. Burnout was measured using the Oldenberg Burnout Inventory (OLBI) and work engagement was measured using the Utrecht Work and Well-being Survey. Multiple regression analyses were performed to identify explanatory variables that were independently associated with burnout and work engagement. The survey response rate was 57%. Total levels of burnout and work engagement in the sample were 31.1% and 34.5%, respectively. Multiple regression analyses showed that shift work, 6-9 years experience, working >20 hours/week, administrative professional stream and being single were associated with higher levels of burnout. There was a positive association between work engagement and nonshift workers, 45 years of age. In this study, gender, income, hours of direct patient care, location of the centre in regional centres or within the private setting did not have an independent effect on the levels of burnout or work engagement. There was a negative association between burnout and work engagement (P engaged in their work. Further research is required to study the effectiveness of interventions to improve personal resources and prevent burnout.

    Since 2007, 96 wild Queensland groupers, Epinephelus lanceolatus, (Bloch), have been found dead in NE Australia. In some cases, Streptococcus agalactiae (Group B Streptococcus, GBS) was isolated. At present, a GBS isolate from a wild grouper case was employed in experimental challenge trials in hatchery-reared Queensland grouper by different routes of exposure. Injection resulted in rapid development of clinical signs including bilateral exophthalmia, hyperaemic skin or fins and abnormal swimming. Death occurred in, and GBS was re-isolated from, 98% fish injected and was detected by PCR in brain, head kidney and spleen from all fish, regardless of challenge dose. Challenge by immersion resulted in lower morbidity with a clear dose response. Whilst infection was established via oral challenge by admixture with feed, no mortality occurred. Histology showed pathology consistent with GBS infection in organs examined from all injected fish, from fish challenged with medium and high doses by immersion, and from high-dose oral challenge. These experimental challenges demonstrated that GBS isolated from wild Queensland grouper reproduced disease in experimentally challenged fish and resulted in pathology that was consistent with that seen in wild Queensland grouper infected with S. agalactiae.

    Classroom teachers located in Queensland, Australia are exposed to high levels of ambient solar ultraviolet as part of the occupational requirement to provide supervision of children during lunch and break times. We investigated the relationship between periods of outdoor occupational radiant exposure and available ambient solar radiation across different teaching classifications and schools relative to the daily occupational solar ultraviolet radiation (HICNIRP) protection standard of 30J/m(2). Self-reported daily sun exposure habits (n=480) and personal radiant exposures were monitored using calibrated polysulphone dosimeters (n=474) in 57 teaching staff from 6 different schools located in tropical north and southern Queensland. Daily radiant exposure patterns among teaching groups were compared to the ambient UV-Index. Personal sun exposures were stratified among teaching classifications, school location, school ownership (government vs non-government), and type (primary vs secondary). Median daily radiant exposures were 15J/m(2) and 5J/m(2)HICNIRP for schools located in northern and southern Queensland respectively. Of the 474 analyzed dosimeter-days, 23.0% were found to exceed the solar radiation protection standard, with the highest prevalence found among physical education teachers (57.4% dosimeter-days), followed by teacher aides (22.6% dosimeter-days) and classroom teachers (18.1% dosimeter-days). In Queensland, peak outdoor exposure times of teaching staff correspond with periods of extreme UV-Index. The daily occupational HICNIRP radiant exposure standard was exceeded in all schools and in all teaching classifications.

    Full Text Available Australian bat lyssavirus (ABLV belongs to the genus Lyssavirus which also includes classic rabies virus and the European lyssaviruses. To date, the only three known human ABLV cases, all fatal, have been reported from Queensland, Australia. ABLV is widely distributed in Australian bats, and any bite or scratch from an Australian bat is considered a potential exposure to ABLV.Potential exposure to ABLV has been a notifiable condition in Queensland since 2005. We analysed notification data for potential exposures occurring between 2009 and 2014. There were 1,515 potential exposures to ABLV notified in Queensland, with an average annual notification rate of 5.6 per 100,000 population per year. The majority of notified individuals (96% were potentially exposed to ABLV via bats, with a small number of cases potentially exposed via two ABLV infected horses and an ABLV infected human. The most common routes of potential exposure were through bat scratches (47% or bites (37%, with less common routes being mucous membrane/broken skin exposure to bat saliva/brain tissue (2.2%. Intentional handling of bats by the general public was the major cause of potential exposures (56% of notifications. Examples of these potential exposures included people attempting to rescue bats caught in barbed wire fences/fruit tree netting, or attempting to remove bats from a home. Following potential exposures, 1,399 cases (92% were recorded as having appropriate post-exposure prophylaxis (PEP as defined in national guidelines, with the remainder having documentation of refusal or incomplete PEP. Up to a quarter of notifications occurred after two days from the potential exposure, but with some delays being more than three weeks. Of 393 bats available for testing during the reporting period, 20 (5.1% had ABLV detected, including four species of megabats (all flying foxes and one species of microbats (yellow-bellied sheathtail bat.Public health strategies should address the

    Full Text Available Abstract Background Patterns of diagnosis and management for men diagnosed with prostate cancer in Queensland, Australia, have not yet been systematically documented and so assumptions of equity are untested. This longitudinal study investigates the association between prostate cancer diagnostic and treatment outcomes and key area-level characteristics and individual-level demographic, clinical and psychosocial factors. Methods/Design A total of 1064 men diagnosed with prostate cancer between February 2005 and July 2007 were recruited through hospital-based urology outpatient clinics and private practices in the centres of Brisbane, Townsville and Mackay (82% of those referred. Additional clinical and diagnostic information for all 6609 men diagnosed with prostate cancer in Queensland during the study period was obtained via the population-based Queensland Cancer Registry. Respondent data are collected using telephone and self-administered questionnaires at pre-treatment and at 2 months, 6 months, 12 months, 24 months, 36 months, 48 months and 60 months post-treatment. Assessments include demographics, medical history, patterns of care, disease and treatment characteristics together with outcomes associated with prostate cancer, as well as information about quality of life and psychological adjustment. Complementary detailed treatment information is abstracted from participants' medical records held in hospitals and private treatment facilities and collated with health service utilisation data obtained from Medicare Australia. Information about the characteristics of geographical areas is being obtained from data custodians such as the Australian Bureau of Statistics. Geo-coding and spatial technology will be used to calculate road travel distances from patients' residences to treatment centres. Analyses will be conducted using standard statistical methods along with multilevel regression models including individual and area-level components

    The survival inequality faced by Indigenous Australians after a cancer diagnosis is well documented; what is less understood is whether this inequality has changed over time and what this means in terms of the impact a cancer diagnosis has on Indigenous people. Survival information for all patients identified as either Indigenous (n=3168) or non-Indigenous (n=211,615) and diagnosed in Queensland between 1997 and 2012 were obtained from the Queensland Cancer Registry, with mortality followed up to 31st December, 2013. Flexible parametric survival models were used to quantify changes in the cause-specific survival inequalities and the number of lives that might be saved if these inequalities were removed. Among Indigenous cancer patients, the 5-year cause-specific survival (adjusted by age, sex and broad cancer type) increased from 52.9% in 1997-2006 to 58.6% in 2007-2012, while it improved from 61.0% to 64.9% among non-Indigenous patients. This meant that the adjusted 5-year comparative survival ratio (Indigenous: non-Indigenous) increased from 0.87 [0.83-0.88] to 0.89 [0.87-0.93], with similar improvements in the 1-year comparative survival. Using a simulated cohort corresponding to the number and age-distribution of Indigenous people diagnosed with cancer in Queensland each year (n=300), based on the 1997-2006 cohort mortality rates, 35 of the 170 deaths due to cancer (21%) expected within five years of diagnosis were due to the Indigenous: non-Indigenous survival inequality. This percentage was similar when applying 2007-2012 cohort mortality rates (19%; 27 out of 140 deaths). Indigenous people diagnosed with cancer still face a poorer survival outlook than their non-Indigenous counterparts, particularly in the first year after diagnosis. The improving survival outcomes among both Indigenous and non-Indigenous cancer patients, and the decreasing absolute impact of the Indigenous survival disadvantage, should provide increased motivation to continue and enhance

    Various policies, plans and initiatives have been implemented to provide safe, quality and culturally competent care to patients within Queensland's health care system. A series of models of maternity care are available in Queensland that range from standard public care to private midwifery care. The current study aimed to determine whether identifying as culturally or linguistically diverse (CALD) was associated with the perceived safety, quality and cultural competency of maternity care from a consumer perspective, and to identify specific needs and preferences of CALD maternity care consumers. Secondary analysis of data collected in the Having a Baby in Queensland Survey 2012 was used to compare the experiences of 655 CALD women to those of 4049 non-CALD women in Queensland, Australia, across three stages of maternity care: pregnancy, labour and birth, and after birth. After adjustment for model of maternity care received and socio-demographic characteristics, CALD women were significantly more likely than non-CALD women to experience suboptimal staff technical competence in pregnancy, overall perceived safety in pregnancy and labour/birth, and interpersonal sensitivity in pregnancy and labour/birth. Approximately 50 % of CALD women did not have the choice to use a translator or interpreter, or the gender of their care provider, during labour and birth. Thirteen themes of preferences and needs of CALD maternity care consumers based on ethnicity, cultural beliefs, or traditions were identified; however, these were rarely met. Findings imply that CALD women in Queensland experience disadvantageous maternity care with regards to perceived staff technical competence, safety, and interpersonal sensitivity, and receive care that lacks cultural competence. Improved access to support persons, continuity and choice of carer, and staff availability and training is recommended.

    This paper establishes reference ranges for hematologic and plasma biochemistry values in wild Black flying-foxes (Pteropus alecto) captured in South East Queensland, Australia. Values were found to be consistent with those of other Pteropus species. Four hundred and forty-seven animals were sampled over 12 months and significant differences were found between age, sex, reproductive and body condition cohorts in the sample population. Mean values for each cohort fell within the determined normal adult reference range, with the exception of elevated levels of alkaline phosphatase in juvenile animals. Hematologic and biochemistry parameters of injured animals showed little or no deviation from the normal reference values for minor injuries, while two animals with more severe injury or abscessation showed leucocytosis, anaemia, thrombocytosis, hyperglobulinemia and hypoalbuminemia.

    In this study, the application of artificial intelligence to monthly and seasonal rainfall forecasting in Queensland, Australia, was assessed by inputting recognized climate indices, monthly historical rainfall data, and atmospheric temperatures into a prototype stand-alone, dynamic, recurrent, time-delay, artificial neural network. Outputs, as monthly rainfall forecasts 3 months in advance for the period 1993 to 2009, were compared with observed rainfall data using time-series plots, root mean squared error (RMSE), and Pearson correlation coefficients. A comparison of RMSE values with forecasts generated by the Australian Bureau of Meteorology's Predictive Ocean Atmosphere Model for Australia (POAMA)-1.5 general circulation model (GCM) indicated that the prototype achieved a lower RMSE for 16 of the 17 sites compared. The application of artificial neural networks to rainfall forecasting was reviewed. The prototype design is considered preliminary, with potential for significant improvement such as inclusion of output from GCMs and experimentation with other input attributes.

    Full Text Available This paper examines the rapid and ad hoc development and interactions of participative citizen communities during acute events, using the examples of the 2011 floods in Queensland, Australia, and the global controversy surrounding Wikileaks and its spokesman, Julian Assange. The self-organising community responses to such events which can be observed in these cases bypass or leapfrog, at least temporarily, most organisational or administrative hurdles which may otherwise frustrate the establishment of online communities; they fast-track the processes of community development and structuration. By understanding them as a form of rapid prototyping, e-democracy initiatives can draw important lessons from observing the community activities around such acute events.

    Sediment samples were taken from six sampling sites in Bramble Bay, Queensland, Australia between February and November in 2012. They were analysed for a range of heavy metals including Al, Fe, Mn, Ti, Ce, Th, U, V, Cr, Co, Ni, Cu, Zn, As, Cd, Sb, Te, Hg, Tl and Pb. Fraction analysis, Enrichment Factors and Principal Component Analysis-Absolute Principal Component Scores (PCA-APCS) were carried out in order to assess metal pollution, potential bioavailability and source apportionment. Cr and Ni exceeded the Australian Interim Sediment Quality Guidelines at some sampling sites, while Hg was found to be the most enriched metal. Fraction analysis identified increased weak acid soluble Hg and Cd during the sampling period. Source apportionment via PCA-APCS found four sources of metals pollution, namely, marine sediments, shipping, antifouling coatings and a mixed source. These sources need to be considered in any metal pollution control measure within Bramble Bay.

    The study investigates and compares the services available in different types of registered retirement villages in Queensland (QLD). A content analysis based on official websites of 175 registered villages in QLD, Australia, is presented. This study identifies 82 services, with activity organisation, emergency response, hairdressing and transportation being most frequently available to residents. The number of services available is associated with the village size and financial type, with residents living in large private villages having access to significantly more services. The research findings reveal the state of the art of current industry practice. They provide useful implications for stakeholders. For instance, residents who prefer to get access to various services should focus more on large private villages. Developers can check their service delivery environment to confirm its balance with residents' competencies. The government can propose innovative initiatives to promote the delivery of appropriate services in villages. © 2017 AJA Inc.

    Greywacke, argillite, greyschist and hypabyssal igneous rocks have been obtained from an Ocean Drilling Program core on the Queensland Plateau and from xenoliths in a volcanic breccia dredged from the crest of the Lord Howe Rise. Low to intermediate detrital quartz contents, 260-240 Ma K-Ar ages, and only moderately radiogenic Sr and Nd isotope compositions, suggest a correlation with the New England Orogen of eastern Australia, rather than with Australia's Lachlan Orogen or other adjacent geological provinces. Our results indicate that the New England Orogen terranes continue towards New Zealand at least as far as the southern Lord Howe Rise. The projected offshore boundaries of the major east Australian orogens are now known with more confidence, and do not appear to require any major cross-orogen offsets.

    Citrus crops are considered to be relatively poor hosts for Queensland fruit fly, Bactrocera tryoni (Froggatt), as for other tephritid species. Australian citrus growers and crop consultants have reported observable differences in susceptibility of different citrus cultivars under commercial growing conditions. In this study we conducted laboratory tests and field surveys to determine susceptibility to B. tryoni of six citrus cultivars [(Eureka lemon (Citrus limon (L.) Osbeck); Navel and Valencia oranges (C. sinensis (L.) Osbeck); and Imperial, Ellendale, and Murcott mandarins (C. reticulata Blanco). The host susceptibility of these citrus cultivars was quantified by a Host Susceptibility Index, which is defined as the number of adult flies produced per gram of fruit infested at a calculated rate of one egg per gram of fruit. The HSI was ranked as Murcott (0.083) > Imperial (0.052) > Navel (0.026) - Ellendale (0.020) > Valencia (0.008) > Eureka (yellow) (0.002) > Eureka (green) (0). Results of the laboratory study were in agreement with the level of field infestation in the four citrus cultivars (Eureka lemon, Imperial, Ellendale, and Murcott mandarins) that were surveyed from commercial orchards under baiting treatments against fruit flies in the Central Burnett district of Queensland. Field surveys of citrus hosts from the habitats not subject to fruit fly management showed that the numbers of fruit flies produced per gram of fruit were much lower, compared with the more susceptible noncitrus hosts, such as guava (Psidium guajava L.), cherry guava (P. littorale Raddi), mulberry (Morus nigra L.), loquat (Eriobotrya japonica (Thunb.) Lindl.), and pear (Pyrus communis L.). Therefore, the major citrus crops commercially cultivated in Australia have a relatively low susceptibility to B. tryoni, with Eureka lemons being a particularly poor host for this tephritid fruit fly.

  17. The Probable Whole of Slope Submarine Landslides of Southeast Queensland, Australia.

    A research cruise aboard the RV Southern Surveyor (SS2013-V01) conducted in January 2013 offshore east Australia collected regional bathymetric data for the seabed of the continental margin of southern Queensland for the seabed bounded by Noosa Heads in the south and Indian Head, Fraser Island in the north. This newly mapped area presents a particularly steep portion of continental slope (5o to 10 o) that presents numerous submarine landslides, including two 'whole-of-slope' features (The Wide Bay Canyon, and Inskip Slides. The slope is also dissected by three large submarine canyons offshore northern Fraser Island, Wide Bay and Noosa Heads (i.e. the Fraser Canyons, the Wide Bay Canyon and the Noosa Canyon). Dredge and core samples were collected from slide scars in the northern, central and southern areas of the bathymetric survey area. The initial examination of the area's bathymetry, the core and dredge sample sedimentology, and determination of biostratigraphic ages for these sediment samples indicates that the larger, submarine slides present in this study area have probably been shed from the slope since the late Pliocene and that canyon incision is currently active on this portion of the slope. In one case, canyon incision is partly responsible for generating slides due to undercutting and removal of the toe of the slope. Slope sediments are dominantly comprised of hemipelagic muds but the presence of massive coarse sands and graded sands in some cores above erosion surfaces that cut into slope mud units is interpreted to indicate that areas of the southern Queensland continental slope are probably subjected to abrasion by grain-flows and turbidites comprised of shelf-derived sands and upper slope sediment. The results from this voyage confirms and extends previous work on the southeastern Australian continental margin that indicates that sediment transport from the shelf to deep water on this margin is dominated by gravity mass transport and that the margin

    The speculation that climate change may impact on sustainable fish production suggests a need to understand how these effects influence fish catch on a broad scale. With a gross annual value of A$ 2.2 billion, the fishing industry is a significant primary industry in Australia. Many commercially important fish species use estuarine habitats such as mangroves, tidal flats and seagrass beds as nurseries or breeding grounds and have lifecycles correlated to rainfall and temperature patterns. Correlation of catches of mullet (e.g. Mugil cephalus) and barramundi ( Lates calcarifer) with rainfall suggests that fisheries may be sensitive to effects of climate change. This work reviews key commercial fish and crustacean species and their link to estuaries and climate parameters. A conceptual model demonstrates ecological and biophysical links of estuarine habitats that influences capture fisheries production. The difficulty involved in explaining the effect of climate change on fisheries arising from the lack of ecological knowledge may be overcome by relating climate parameters with long-term fish catch data. Catch per unit effort (CPUE), rainfall, the Southern Oscillation Index (SOI) and catch time series for specific combinations of climate seasons and regions have been explored and surplus production models applied to Queensland's commercial fish catch data with the program CLIMPROD. Results indicate that up to 30% of Queensland's total fish catch and up to 80% of the barramundi catch variation for specific regions can be explained by rainfall often with a lagged response to rainfall events. Our approach allows an evaluation of the economic consequences of climate parameters on estuarine fisheries, thus highlighting the need to develop forecast models and manage estuaries for future climate change impact by adjusting the quota for climate change sensitive species. Different modelling approaches are discussed with respect to their forecast ability.

  19. Understanding the geomorphology of macrochannel systems for flood risk management in Queensland, Australia

    2016-04-01

    The year 2010-2011 was the wettest on record for the state of Queensland, Australia producing catastrophic floods. A tropical low pressure system in 2013 delivered further extreme flood events across South East Queensland (SEQ) which prompted state and local governments to conduct studies into flood magnitude and frequency in the region and catchment factors contributing to flood hazards. The floods in the region are strongly influenced by El Nino-Southern Oscillation (ENSO) phenomenon, but also modulated by the Interdecadal Pacific Oscillation (IPO) which leads to flood and drought dominated regimes and high hydrological variability. One geomorphic feature in particular exerted a significant control on the transmission speed, the magnitude of flood inundation and resultant landscape resilience. This feature was referred to as a 'macrochannel', a term used to describe a 'large-channel' which has bankfull recurrence intervals generally greater than 10 years. The macrochannels display non-linear downstream hydraulic geometry which leads to zones of flood expansion (when hydraulic geometry decreases) and zones of flood contraction (when hydraulic geometry increases). The pattern of contraction and expansion zones determines flood hazard zones. The floods caused significant wet flow bank mass failures that mobilised over 1,000,000 m3 of sediment in one subcatchment. Results suggest that the wetflow bank mass failures are a stage in a cyclical evolution process which maintains the macrochannel morphology, hence channel resilience to floods. Chronological investigations further show the macrochannels are laterally stable and identify periods of heightened flood activity over the past millennium and upper limits on flood magnitude. This paper elaborates on the results of the geomorphic investigations on Lockyer Creek in SEQ and how the results have alerted managers and policy makers to the different flood responses of these systems and how flood risk management plans can

    The 2010-2011 Queensland floods resulted in the most deaths from a single flood event in Australia since 1916. This article analyses the information on these deaths for comparison with those from previous floods in modern Australia in an attempt to identify factors that have contributed to those deaths. Haddon's Matrix, originally designed for prevention of road trauma, offers a framework for understanding the interplay between contributing factors and helps facilitate a clearer understanding of the varied strategies required to ensure people's safety for particular flood types. Public reports and flood relevant literature were searched using key words 'flood', 'fatality', 'mortality', 'death', 'injury' and 'victim' through Google Scholar, PubMed, ProQuest and EBSCO. Data relating to reported deaths during the 2010-2011 Queensland floods, and relevant data of previous Australian flood fatality (1997-2009) were collected from these available sources. These sources were also used to identify contributing factors. There were 33 deaths directly attributed to the event, of which 54.5% were swept away in a flash flood on 10 January 2011. A further 15.1% of fatalities were caused by inappropriate behaviours. This is different to floods in modern Australia where over 90% of deaths are related to the choices made by individuals. There is no single reason why people drown in floods, but rather a complex interplay of factors. The present study and its integration of research findings and conceptual frameworks might assist governments and communities to develop policies and strategies to prevent flood injury and fatalities. © 2013 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

    Little is known about the threat of mercury (Hg) to consumers in food webs of Australia's wet-dry tropics. This is despite high concentrations in similar biomes elsewhere and a recent history of gold mining that could lead to a high degree of exposure for biota. We analysed Hg in water, sediments, invertebrates and fishes in rivers and estuaries of north Queensland, Australia to determine its availability and biomagnification in food webs. Concentrations in water and sediments were low relative to other regions of Hg concern, with only four of 138 water samples and five of 60 sediment samples above detection limits of 0.1 {mu}g L{sup -1} and 0.1 {mu}g g{sup -1}, respectively. Concentrations of Hg in fishes and invertebrates from riverine and wetland food webs were well below international consumption guidelines, including those in piscivorous fishes, likely due to low baseline concentrations and limited rates of biomagnification (average slope of log Hg vs. {delta}{sup 15}N = 0.08). A large fish species of recreational, commercial, and cultural importance (the barramundi, Lates calcarifer), had low concentrations that were below consumption guidelines. Observed variation in Hg concentrations in this species was primarily explained by age and foraging location (floodplain vs. coastal), with floodplain feeders having higher Hg concentrations than those foraging at sea. These analyses suggest that there is a limited threat of Hg exposure for fish-eating consumers in this region. - Highlights: Black-Right-Pointing-Pointer Hg concentrations in freshwaters and sediments of north Queensland were low. Black-Right-Pointing-Pointer Biomagnification of Hg through riverine food webs was limited. Black-Right-Pointing-Pointer Barramundi, a predatory fish, had low concentrations meaning low risk for consumers. Black-Right-Pointing-Pointer Floodplain-feeding barramundi had higher Hg concentrations than coastal feeders.

    Fruits of Restionaceae and seeds of Typhaceae are described from a latest Eocene-Oligocene mudstone underlying oil shales in a subsurface sequence near Rockhampton, coastal central Queensland. The Restionaceae fruits are unilocular and encase a single pendulous orthotropous seed with a structured micropylar cap, which may be tannin filled. These are allocated to Restiocarpum gen. nov., which has as its type Restiocarpum latericum sp. nov., and four other taxa described herein; Restiocarpum tesselatum sp. nov., Restiocarpum verrucatum sp. nov., Restiocarpum laeve sp. nov., and Restiocarpum fusiforme sp. nov. Typhaspermum cooksoniae gen. et sp. nov., which accommodates asymmetric claviform seeds, is interpreted as a member of the Typhaceae based on the presence of a lid-like operculum, bitegmic wall, and chalazal cavity.Reconstruction of the source plant community emphasizes similarities to restiad swamps of present day Wallum (swamp heathland) vegetation which is extensively developed along the Queensland coast. Biogeographic implications for the Restionaceae and Typhaceae are discussed.

    Full Text Available Objective : To describe the demographic and clinical characteristics of patients hospitalized with pandemic A(H1N1 2009 infection in Queensland, Australia between 25 May and 3 October 2009 and to examine the relationship between timing of antiviral treatment and severity of illness.Method: Using data from the Queensland Health EpiLog information system, descriptive analysis and logistic regression modelling were used to describe and model factors which influence patient outcomes (death, admission to intensive care unit and/or special care unit. Data on patients admitted to hospital in Queensland with confirmed pandemic A(H1N1 2009 infection were included in this analysis.Results: 1236 patients with pandemic A(H1N1 2009 infection were admitted to hospitals in Queensland during the study period. Of the total group: 15% were admitted to an intensive care unit or special care unit; 3% died; 34% were under the age of 18 years and 8% were 65 years of age or older; and 55% had at least one underlying medical condition. Among the 842 patients for whom data were available regarding the use of antiviral drugs, antiviral treatment was initiated in 737 (87.5% patients with treatment commencing at a median of one day (range 1–33 days after onset of illness. Admission to an intensive care unit or special care unit (ICU/SCU or death was significantly associated with increased age, lack of timeliness of antiviral treatment, chronic renal disease and morbid obesity.Discussion: Early antiviral treatment was significantly associated with lower likelihood of ICU/SCU admission or death. Early antiviral treatment for influenza cases may therefore have important public health implications.

    To define characteristics of all-terrain vehicle (ATV) crashes occurring in north Queensland from March 2004 till June 2007 with the exploration of associated risk factors. Descriptive analysis of ATV crash data collected by the Rural and Remote Road Safety Study. Rural and remote north Queensland. Forty-two ATV drivers and passengers aged 16 years or over hospitalised at Atherton, Cairns, Mount Isa or Townsville for at least 24 hours as a result of a vehicle crash. Demographics of participants, reason for travel, nature of crash, injuries sustained and risk factors associated with ATV crash. The majority of casualties were men aged 16-64. Forty-one per cent of accidents occurred while performing agricultural tasks. Furthermore, 39% of casualties had less than one year's experience riding ATVs. Over half the casualties were not wearing a helmet at the time of the crash. Common injuries were head and neck and upper limb injuries. Rollovers tended to occur while performing agricultural tasks and most commonly resulted in multiple injuries. Considerable trauma results from ATV crashes in rural and remote north Queensland. These crashes are not included in most general vehicle crash data sets, as they are usually limited to events occurring on public roads. Minimal legislation and regulation currently applies to ATV use in agricultural, recreational and commercial settings. Legislation on safer design of ATVs and mandatory courses for riders is an essential part of addressing the burden of ATV crashes on rural and remote communities.

    The water mouse is a small and vulnerable rodent present in coastal areas of south-west Papua New Guinea, and eastern Queensland and the Northern Territory of Australia. Current knowledge regarding the distribution of the water mouse is incomplete and the loss of one local population has been documented in southeast Queensland, a region where pressures from urban and industrial development are increasing. Water mouse populations have not been studied intensively enough to enable the primary factors responsible for the local decline to be identified. We surveyed the distribution and density of the water mouse along the Maroochy River of southeast Queensland, near the southern extent of the species' range, to gather baseline data that may prove valuable for detecting any future decline in this population's size or health. All areas of suitable habitat were surveyed on foot or by kayak or boat over a three-year period. We found 180 water mouse nests, of which ~94% were active. Permanent camera monitoring of one nest and limited supplementary live trapping suggested that up to three individual mice occupied active nests. Water mouse density was estimated to be 0.44 per hectare of suitable habitat along the Maroochy River. Should future monitoring reveal an adverse change in the water mouse population on the Maroochy River, a concerted effort should be made to identify contributing factors and address proximate reasons for the decline.

    Full Text Available The epidemiology, clinical presentation and management of melioidosis vary around the world.

    The neurological, clinical and pathological findings and endoparasites in 10 wild tawny frogmouths (Podargus strigoides) presented to the Australian Wildlife Hospital in Beerwah, Queensland during a 28-day period in May 2009 are reported. Affected birds had a history of being found in poor body condition on the ground and unable to fly. Clinical examination revealed paresis with variable but generally weakened deep pain responses, withdrawal reflexes and an inability to perch. Severely affected birds that failed to respond to anti-inflammatory, antibiotic and anthelmintic treatments all had larval Angiostrongylus cantonensis in the brain and or spinal cord, with occasional larvae found in the visceral organs. Other parasites detected included the liver fluke, Brachylecithum podargi, the intestinal nematode, Allodapa suctoria, an unidentified species of Trichostrongylus and unidentified cestodes. Gametocytes of Leucocytozoon sp. were found in peripheral blood smears and low numbers of microfilariae were found in histological sections of various blood vessels of several birds. However, no adult filarioids were recovered. Unidentified subcutaneous mites were identified in the connective tissue of the thoracic inlet. Attempts to treat two birds with ivermectin or oxfendazole-praziquantel were unsuccessful, but a third bird treated with a combination of steroidal and non-steroidal anti-inflammatory therapy followed by moxidectin steadily recovered, such that by 6 weeks post presentation its ability to perch, grasp, fly and judge distances was considered normal and it was subsequently released.

    Research shows that stress in pregnancy has powerful and enduring effects on many facets of child development, including increases in behavior problems and neurodevelopmental disorders. Theory of mind is an important aspect of child development that is predictive of successful social functioning and is impaired in children with autism. A number of factors related to individual differences in theory of mind have been identified, but whether theory of mind development is shaped by prenatal events has not yet been examined. In this study we utilized a sudden onset flood that occurred in Queensland, Australia in 2011 to examine whether disaster-related prenatal maternal stress predicts child theory of mind and whether sex of the child or timing of the stressor in pregnancy moderates these effects. Higher levels of flood-related maternal subjective stress, but not objective hardship, predicted worse theory of mind at 30 months (n=130). Further, maternal cognitive appraisal of the flood moderated the effects of stress in pregnancy on girls' theory of mind performance but not boys'. These results illuminate how stress in pregnancy can shape child development and the findings are discussed in relation to biological mechanisms in pregnancy and stress theory.

A higher proportion of owners could be contacted when the microchip had no problems, compared to those with problems (dogs, 93% vs. 70%; cats, 75% vs. 41%. The proportion of animals reclaimed declined significantly between microchipped animals with no data problems, microchipped animals with data problems and non-microchipped animals—87%, 69%, and 37%, respectively, for dogs and 61%, 33%, and 5%, respectively, for cats. Strategies are needed to increase the accuracy of microchip data to facilitate the reclaiming of stray dogs and cats.

    Full Text Available Background/Aims. Professional wine tasters face a hidden occupational hazard due to the high acid content in wine. This study evaluates the self-perceived dentinal sensitivity and erosive effects of wine on the professional wine tasters of the Granite Belt and the Scenic Rim regions of South East Queensland, Australia. Methods. Seventy wineries were contacted and participants were surveyed about their professional wine tasting experience and oral health. Participants were also required to rate their tooth sensitivity prior to being examined for erosion using a modified Smith & Knight tooth wear index. The data were analysed using Mann Whitney U test and Spearman’s correlation test. Results. The results showed that most participants (25 males, 22–66 yrs, brushed twice a day; however, the majority did not floss daily and had limited knowledge of the erosive effect of wine. There was a direct correlation between years of wine tasting, age of participants, and the erosion index. Correlation was not observed between the participant’s sensitivity index and erosion index. Conclusion. The lack of significant experience of dentinal hypersensitivity amongst professional wine tasters should not prevent oral health practitioners from providing necessary counselling and undertaking preventive measures, as tooth wear can have serious long-term effect on oral health of an individual.

    Australian snubfin and Indo-Pacific humpback dolphins co-occur throughout most of their range in coastal waters of tropical Australia. Little is known of their ecology or acoustic repertoires. Vocalizations from humpback and snubfin dolphins were recorded in two locations along the Queensland coast during 2008 and 2010 to describe their vocalizations and evaluate the acoustic differences between these two species. Broad vocalization types were categorized qualitatively. Both species produced click trains burst pulses and whistles. Principal component analysis of the nine acoustic variables extracted from the whistles produced nine principal components that were input into discriminant function analyses to classify 96% of humpback dolphin whistles and about 78% of snubfin dolphin calls correctly. Results indicate clear acoustic differences between the vocal whistle repertoires of these two species. A stepwise routine identified two principal components as significantly distinguishable between whistles of each species: frequency parameters and frequency trend ratio. The capacity to identify these species using acoustic monitoring techniques has the potential to provide information on presence/absence, habitat use and relative abundance for each species.

    The Jurassic to Cretaceous sedimentary rocks of the Surat Basin in southeast Queensland host a significant volume of coal seam gas resources. Consequently, knowledge of the in situ stress is important for coal permeability enhancement and wellbore stability. Using wireline log data and direct stress measurements, we have calculated stress orientations from 36 wells and stress magnitudes from 7 wells across the Surat Basin. Our results reveal a relationship between high tectonic stress and proximity to structures within the underlying "basement" rocks. The influence of tectonic stresses is diminished with depth in areas with thicker sedimentary cover that are relatively far from the basement structures. We suggest that this relationship is due to the redistribution of in situ stresses around areas where basement is shallower and where basement structures, such as the Leichhardt-Burunga Fault System, are present. This behavior is explained by a lower rigidity in the thickest basin cover, which reduces the ability to maintain higher tectonic stress. Over the entire Surat Basin, a significant amount of variability in in situ stress orientation is observed. The authors attribute this stress variability to complex plate boundary interactions on the northern and eastern margins of the Indo-Australian Plate.

  14. Relations between coal petrology and gas content in the Upper Newlands Seam, Central Queensland, Australia

    The Upper Newlands Seam in the northern Bowen Basin, Queensland Australia consists of six benches (A-F) that have different petrographic assemblages. Benches C and E contain relatively abundant inertodetrinite and mineral matter, as well as anomalously high reflectance values; these characteristics support a largely allochthonous, detrital origin for the C and E benches. Fractures and cleats in the seam show a consistent orientation of northeast-southwest for face cleats, and a wide range of orientations for fractures. Cleat systems are well developed in bright bands, with poor continuity in the dull coal. Both maceral content and cleat character are suggested to influence gas drainage in the upper Newlands Seam. A pronounced positive correlation between vitrinite abundance and gas desorption data suggests more efficient drainage from benches with abundant vitrinite. Conversely, inertinite-rich benches are suggested to have less efficient drainage, and possibly retain gas within pore spaces, which could increase the outburst potential of the coal. ?? 2001 Elsevier Science B.V.

    2003-01-01

    Full Text Available Governments and other policy makers are concerned with the gap in home Internet usage between people from metropolitan and rural areas. A survey conducted in Central Queensland, Australia examined differences in home Internet usage patterns between young and old, male and female, people in urban and rural areas, married and unmarried, well-educated and less educated, rich and poor, and employed and unemployed and found significant differences. These results highlight areas for further research and provide a basis for government agencies and industries to consider these associations in future policy formulation for regional development using ICT. The research suggested that further research should be conducted to monitor consuming behaviors of the youngest age group in Internet use for entertainment and information search in order to detect possible Internet overuse or addiction. In addition, further research should be conducted to find out what people search for on the Internet, and if for employment opportunities, financial incentives are suggested for the unemployed people.

    Queensland fruit fly, Bactrocera tryoni (Q-fly), is a major pest of horticultural crops in eastern Australia. Lures that attract male Q-fly are important for detection of incursions and outbreaks, monitoring of populations, and control by mass trapping and male annihilation. Cuelure, an analog of naturally occurring raspberry ketone, is the standard Q-fly lure, but it has limited efficacy compared with lures that are available for some other fruit flies such as methyl eugenol for B. dorsalis. Melolure is a more recently developed raspberry ketone analog that has shown better attraction than cuelure in some field studies but not in others. A novel fluorinated analog of raspberry ketone, raspberry ketone trifluoroacetate (RKTA), has been developed as a potential improvement on cuelure and melolure. RKTA placed on laboratory cages containing 2-week-old Q-flies elicited strong behavioral responses from males. Quantification of Q-fly responses in these cages, using digital images to estimate numbers of flies aggregated near different lures, showed RKTA attracted and arrested significantly more flies than did cuelure or melolure. RKTA shows good potential as a new lure for improved surveillance and control of Q-fly.

    Full Text Available Abstract Background There are few cost-minimisation studies in telemedicine. We have compared the actual costs of providing a telepaediatric service to the potential costs if patients had travelled to see the specialist in person. Methods In November 2000, we established a novel telepaediatric service for selected regional hospitals in Queensland. Instead of transferring patients to Brisbane, the majority of referrals to specialists in Brisbane were dealt with via videoconference. Since the service began, 1499 consultations have been conducted for a broad range of paediatric sub-specialities including burns, cardiology, child development, dermatology, diabetes, endocrinology, gastroenterology, nephrology, neurology, oncology, orthopaedics, paediatric surgery and psychiatry. Results During a five year period, the total cost of providing 1499 consultations through the telepaediatric service was A$955,996. The estimated potential cost of providing an outpatient service to the same number of patients at the Royal Children's Hospital in Brisbane was A$1,553,264; thus, telepaediatric services resulted in a net saving of approximately A$600,000 to the health service provider. Conclusion Telepaediatrics was a cheaper method for the delivery of outpatient services when the workload exceeded 774 consultations. A sensitivity analysis showed that the threshold point was most sensitive to changes related to patient travel costs, coordinator salaries and videoconference equipment costs. The study showed substantial savings for the health department, mainly due to reduced costs associated with patient travel.

    In this study,the application of artificial intelligence to monthly and seasonal rainfall forecasting in Queensland,Australia,was assessed by inputting recognized climate indices,monthly historical rainfall data,and atmospheric temperatures into a prototype stand-alone,dynamic,recurrent,time-delay,artificial neural network.Outputs,as monthly rainfall forecasts 3 months in advance for the period 1993 to 2009,were compared with observed rainfall data using time-series plots,root mean squared error (RMSE),and Pearson correlation coefficients.A comparison of RMSE values with forecasts generated by the Australian Bureau of Meteorology's Predictive Ocean Atmosphere Model for Australia (POAMA)-1.5 general circulation model (GCM) indicated that the prototype achieved a lower RMSE for 16 of the 17 sites compared.The application of artificial neural networks to rainfall forecasting was reviewed.The prototype design is considered preliminary,with potential for significant improvement such as inclusion of output from GCMs and experimentation with other input attributes.

  19. Managing urban water crises: adaptive policy responses to drought and flood in Southeast Queensland, Australia

    2014-06-01

    Full Text Available In this case study, I examine the quality of decision-making under conditions of rapidly evolving urban water crises, and the adaptive policy challenges of building regional resilience in response to both drought and flood. Like other regions of Australia, Southeast Queensland has been subject to substantial cycles of drought and flood. I draw on resilience literature concerning sustainability, together with governance literature on policy change, to explain the changing awareness of urban water crises and the strategic options available for addressing these crises in this case study. The problem of resilience thinking opens up a number of important questions about the efficacy and adaptability of the policy system. The case provides insights into the interplay between the ways in which problems are framed, the knowledge bases required for planning and decision-making, the collaborative governance processes required for managing complex and rapidly evolving issues, and the overall capacity for policy learning over time. Regional resilience was proclaimed as a policy goal by government, but the practices remained largely anchored in traditional technical frameworks. Centralized investment decisions and governance restructures provoked conflict between levels of government, undermining the capacity of stakeholders to create more consensual approaches to problem-solving and limiting the collective learning that could have emerged.

    This study assesses the prevalence of disinfection by-product (DBP) precursors in some Southeast Queensland drinking water sources by conducting formation potential experiments for the four regulated trihalomethanes (THMs), and the potent carcinogen, N-nitrosodimethylamine (NDMA). NDMA formation potentials were consistently low (Water Guideline (250 μg/L). NDMA concentration of finished drinking waters was also monitored and found to be UV/H(2)O(2) pre-treatment was effective in producing water with very low THMs concentrations, and UV irradiation was an effective method for NDMA degradation. H(2)O(2) was not required for the observed NDMA degradation to occur. Coagulation using alum, ferric chloride or poly(diallyldimethylammonium chloride) (polyDADMAC) was ineffective in removing DBPs precursors from the source water studied, irrespective of the low dissolved organic carbon (DOC) and dissolved organic nitrogen (DON) attained. Rather, coagulation with polyDADMAC caused an increase in NDMA formation potential upon chloramination, and all coagulants led to an increased tTHM formation potential upon chlorination due to the high bromide concentration of the source water studied.

    2008-04-01

    An assessment of radiologically enhanced residual materials generated during treatment of domestic water supplies in southeast Queensland, Australia, was conducted. Radioactivity concentrations of U-238, Th-232, Ra-226, Rn-222, and Po-210 in water, sourced from both surface water catchments and groundwater resources were examined both pre- and post-treatment under typical water treatment operations. Surface water treatment processes included sedimentation, coagulation, flocculation and filtration, while the groundwater was treated using cation exchange, reverse osmosis, activated charcoal or methods similar to surface water treatment. Waste products generated as a result of treatment included sediments and sludges, filtration media, exhausted ion exchange resin, backwash and wastewaters. Elevated residual concentrations of radionuclides were identified in these waste products. The waste product activity concentrations were used to model the radiological impact of the materials when either utilised for beneficial purposes, or upon disposal. The results indicate that, under current water resource exploitation programs, reuse or disposal of the treatment wastes from large scale urban water treatment plants in Australia do not pose a significant radiological risk.

    Suicide rates among Indigenous Australian children are higher than for other Australian children. The current study aimed to identify factors associated with Indigenous child suicide when compared to other Australian children. Using the Queensland Suicide Register, suicides in Indigenous children (10-14 years) and other Australian children in the same age band were compared. Between 2000 and 2010, 45 child suicides were recorded: 21 of Indigenous children and 24 of other Australian children. This corresponded to a suicide rate of 10.15 suicides per 100,000 for Indigenous children - 12.63 times higher than the suicide rate for other Australian children (0.80 per 100,000). Hanging was the predominant method used by all children. Indigenous children were significantly more likely to suicide outside the home, to be living outside the parental home at time of death, and be living in remote or very remote areas. Indigenous children were found to consume alcohol more frequently before suicide, compared to other Australian children. Current and past treatments of psychiatric disorders were significantly less common among Indigenous children compared to other Australian children. Western conceptualisation of mental illness may not adequately embody Indigenous people's holistic perspective regarding mental health. Further development of culturally appropriate suicide prevention activities for Aboriginal and Torres Strait Islander children is required. © 2014 Public Health Association of Australia.

    Suicide among children under the age of 15 years is a leading cause of death. The aim of the current study is to identify demographic, psychosocial, and psychiatric factors associated with child suicides. Using external causes of deaths recorded in the Queensland Child Death Register, a case-control study design was applied. Cases were suicides of children (10-14 years) and adolescents (15-17 years); controls were other external causes of death in the same age band. Between 2004 and 2012, 149 suicides were recorded: 34 of children aged 10-14 years and 115 of adolescents aged 15-17 years. The gender asymmetry was less evident in child suicides and suicides were significantly more prevalent in indigenous children. Children residing in remote areas were significantly more likely to die by suicide than other external causes compared with children in metropolitan areas. Types of precipitating events differed between children and adolescents, with children more likely to experience family problems. Disorders usually diagnosed during infancy, childhood, and adolescence (e.g., ADHD) were significantly more common among children compared with adolescents who died by suicide. Psychosocial and environmental aspects of children, in addition to mental health and behavioral difficulties, are important in the understanding of suicide in this age group and in the development of targeted suicide prevention.

    A 3--5% nickel enriched laterite in the Greenvale Ore Body of Queensland, Australia, is the result of weathering a serpentinized ultramafic intrusion. Variations in solubilities and drainage, typical of laterite deposits, resulted in the formation of three primary zones: (1) the Saprolite zone, (2) the Intermediate zone, and (3) the Limonite zone. Within these zones, clay mineral species with distinct chemistries and/or mineralogies have been identified, including: Ni-rich Smectite, Halloysite, and Palygorskite. Clay minerals were analyzed using powder X-ray diffraction and SEM. Bulk chemistry was determined by X-ray fluorescence in an attempt to better constrain the chemical conditions at the time of formation of the clay minerals. Results indicate a complex drainage system and history for the Greenvale Ore Body. Based on the distribution of ore grade material, it is apparent that the deposit was initially characterized by fracture controlled drainage. Owing to precipitation of Ni-rich smectite, halloysite, and palygorskite, subsequent alteration of the ore body drainage network and/or local climate can be inferred.

  5. Climate change impacts on the water balance of coastal and montane rainforests in northern Queensland, Australia

    2012-12-01

    SummaryHow the water balance of coastal and montane rainforests in northern Queensland could change in response to climate change was examined using physically based models of interception and transpiration along with long term weather records. Future rainfall and temperature changes were based on the most recent climate modelling for the region and were assumed to fall within the range ±20% for rainfall with a temperature increase of 1-3 K. Climate change will affect the water balance of Australian rainforests primarily via rainfall changes rather than temperature. Any given change in rainfall produces a greater change in downstream runoff, the amplification ranging from 1.1 to 1.5 in the wet season to a factor of 12 in the dry season. Changes in wet season rainfall (80% of the annual total) dominate the total annual amount of water released for downstream flow, but dry season rainfall (20% of the annual total) changes are also very important as they affect onset and the duration of the period when there is no runoff. This period is currently ˜110 days and this would change by ±30 days under the above climate scenarios. There are also potential in situ impacts of climate change that affect how long the rainforest canopy is wet, which may have important implications for the epiphytes and mosses that depend on these wet canopy conditions. Similarly there may be significant impacts on downstream freshwater species whose life cycles are adapted to the current dry season flow regime.

    Full Text Available Abstract Background Suicide in mentally ill subjects, like schizophrenics, remains unbearably frequent in Australia and elsewhere. Since these patients are known to constitute a high-risk group, suicide in them should be amongst the most preventable ones. The objective of this study is to investigate the frequency of suicide communication in subjects with reported history of schizophrenia who completed suicide. Method The Queensland Suicide Register (QSR was utilised to identify suicide cases. Frequency of suicide communication was examined in subjects with schizophrenia, and compared with persons with other psychiatric conditions and with subjects with no reported diagnosis. Socio-demographic variables, history of suicidal behaviour, pharmacological treatment and mental health service utilisation were also compared among the three groups. Results and discussion Subjects with a reported diagnosis of schizophrenia comprised 7.2% (n = 135 of the 1,863 suicides included in this study. Subjects with schizophrenia and those with other psychiatric disorders communicated their suicide intent more frequently than those with no psychiatric diagnosis, and persons with schizophrenia communicated their intent more than those with other psychiatric diagnoses. Seventy one per cent of schizophrenia subjects had contact with a mental health professional within the three months prior to suicide. Conclusion The fact that subjects with schizophrenia had the highest prevalence of suicide intent communication could offer concrete opportunities for suicide prevention.

  7. Dwarfism and feeding behaviours in Oligo–Miocene crocodiles from Riversleigh, northwestern Queensland, Australia

    2016-02-01

    Full Text Available Instances of dwarfism in the fossil record are of interest to palaeontologists because they often provide insight into aspects of palaeoecology. Fossil species of Australian-Pacific mekosuchine genus Mekosuchus have been described as dwarf, primarily terrestrial crocodiles, in contrast with the nearly ubiquitous semi-aquatic habitus of extant crocodilians (Willis 1997. This hypothesis has been difficult to test because of limited knowledge of the cranial and postcranial skeleton of extinct taxa and the continuous nature of crocodilian growth. New crocodilian vertebral material from Riversleigh, northwestern Queensland, tentatively referred to Mekosuchus whitehunterensis Willis, 1997, displays morphological maturity indicative of adult snout-vent length little over a half-meter, proportionally smaller than extant dwarf taxa. Further, this material displays morphology that indicates a relatively large epaxial neck musculature for its body-size. These attributes suggest this dwarf mekosuchine employed unusual feeding behaviours. The ability to perform normal death-roll, de-fleshing behaviours would be limited in a mekosuchine of such small size. Given the powerful neck muscles and other anatomical features, it is more likely that this mekosuchine killed and/or dismembered its prey using a relatively forceful lifting and shaking of the head.

    In 1847 the anaesthetic and analgesic properties of chloroform were discovered. This technology generated a new era for midwifery: mothers could be relieved of pain in childbirth. The introduction of chloroform for childbirth saw increasing medical dominance in obstetrics, traditionally in the hands of the midwife. At the same time the use of chloroform sparked a medical and moral controversy which lasted for several decades. On the one hand women were destined by the 'curse of Eve' to experience pain during childbirth; on the other, medical humanitarians and practitioners believed that there were technical and moral reasons for alleviating pain in childbirth. In concentrating on the debate historians have largely ignored the reactions of mothers to the introduction of the technology. This paper explores changing attitudes to childbearing within the context of colonial Queensland society, 1860-90, by examining the correspondence of an upper-class mother. Her education and liberal outlook, and a certain ambivalence towards motherhood, all influenced her attitude to the use of chloroform and the process of childbirth.

    The results of a survey describing the attitude to renewable energy supply (RES) amongst tourism accommodation providers in Queensland, Australia, are presented. A 65% response rate was achieved. Results showed that 9.2% of respondents had some form of RES, and that the majority of operators were interested in RES but mixed in opinions as to its marketing value for their operation. Tourist operators believed their industry is resistant to RES implementation due to reservations regarding RES power supply limitations, reliability and economic viability. Possession of a RES by the respondent did not affect this attitude. Analysis of variation in response with geographical position revealed a coastal versus interior difference. Likewise, a breakdown of responses according to accommodation type indicated that accommodation size had a significant bearing on operator opinion. Higher proportions of respondents from large operations such as large hotels and self-catering accommodation returned affirmative responses regarding RES marketing capabilities and confidence in RES than the smaller operations, which included small hotels, stations and villas/cabins.

    Parthenium weed is a highly invasive alien species in more than 40 countries around the world. Along with severe negative effects on human and animal health and crop production, it also causes harm to ecosystem functioning by reducing the native plant species biodiversity. However, its impacts on native plant species, especially in pasture communities, are less known. Given parthenium weed causes substantial losses to Australian pastures' productivity, it is crucial to estimate its impact on pasture communities. This study evaluates the impact of parthenium weed upon species diversity in a pasture community at Kilcoy, south east Queensland, Australia. Sub-sites containing three levels of parthenium weed density (i.e. high, low and zero) were chosen to quantify the above- and below-ground plant community structure. Species richness, diversity and evenness were all found to be significantly reduced as the density of parthenium weed increased; an effect was evident even when parthenium weed was present at relatively low densities (i.e. two plants m(-2)). This trend was observed in the summer season as well as in winter season when this annual weed was absent from the above-ground plant community. This demonstrates the strong impact that parthenium weed has upon the community composition and functioning throughout the year. It also shows the long-term impact of parthenium weed on the soil seed bank where it had displaced several native species. So, management options used for parthenium weed should also consider the reduction of parthenium weed seed bank along with controlling its above-ground populations.

    Outdoor workers are at risk of developing skin cancer because they are exposed to high levels of harmful ultraviolet radiation. The Outdoor Workers Sun Protection Project investigated sun protection strategies for high risk outdoor workers in rural and regional Australia. Fourteen workplaces (recruitment rate 37%) across four industries in rural and regional Queensland, Australia were recruited to the OWSPP. In 2011-2012, data were collected using pre- and post-intervention interviews and discussion groups. This article presents two workplaces as case study examples. The flat organisational structure of workplace 1 supported the implementation of the Sun Safety Action Plan (SSAP), whilst the hierarchical organisational nature of workplace 2 delayed implementation of the SSAP. Neither workplace had an existing sun protection policy but both workplaces adopted one. An effect related to the researchers' presence was seen in workplace 1 and to a lesser degree in workplace 2. Overt reciprocity was seen between management and workers in workplace 1 but this was not so evident in workplace 2. In both workplaces, the role of the workplace champion was pivotal to SSAP progression. These two case studies highlight a number of contextually bound workplace characteristics related to sun safety. These issues are (1) the structure of workplace, (2) policy, (3) an effect related to the researchers' presence, (4) the workplace champion and (5) reciprocity. There are several recommendations from this article. Workplace health promotion strategies for sun safety need to be contextualised to individual workplaces to take advantage of the strengths of the workplace and to build capacity.

    Tidal flooding and surface drainage patterns have often been used to describe mangrove species zonation. However, in mangrove forests exhibiting little topography, ambiguous species distributions and/or few species, such approaches are ineffective. We identified four physiognomic mangrove forest types (Riverine, Fringing, Overwash and Basin) at Coombabah Lake, a tidal lake in southeast Queensland, Australia and investigated tidal flooding patterns using synoptic surveys of tidal observations at the local Standard Port combined with local water depth observation. Subsequently three sub-types of the basin forest type were identified: (1) Deep Basin Forest with mature trees, ˜50 cm standing water and ˜3 tides per year; (2) Medium Depth Basin Forest with intermediate tree development, ˜15-30 cm standing water and 20-40 tides per year; and (3) Shallow Basin Forest with relatively recent mangrove establishment, 5-15 cm standing water and ˜80 tides per year. These three basin sub-types were found to flood at different tide heights with the Shallow Basin flooding for tides above mean high water springs and the Deep Basin flooding only for tide heights approaching the highest astronomical tide. We propose that these basin types represent a succession in mangrove forest development that corresponds with increasing water depth and tree maturation over time. The succession not only represents increasing age but also change in basin substrate composition. This is manifest as increasing pneumatophore density and an increasing area of basin surface occupied by contiguous pneumatophore cover. As a result, it seems that mangrove development is able to modify tidal flooding into the basin by increasingly impeding water movement.

  13. Habitat and Biodiversity of On-Farm Water Storages: A Case Study in Southeast Queensland, Australia

    2008-02-01

    On-farm water storages (locally known as farm dams or farm ponds) are an important part of many agricultural landscapes, as they provide a reliable source of water for irrigation and stock. Although these waterbodies are artificially constructed and morphologically simple, there is increasing interest in their potential role as habitat for native flora and fauna. In this article, we present results from a case study which examined the habitat characteristics (such as water physical and chemical parameters, benthic metabolism, and macrophyte cover) and the macrophyte and macroinvertebrate biodiversity of eight farm ponds on four properties in the Stanley Catchment, Southeast Queensland, Australia. Each landowner was interviewed to allow a comparison of the management of the ponds with measured habitat and biodiversity characteristics, and to understand landowners’ motivations in making farm pond management decisions. The physical and chemical water characteristics of the study ponds were comparable to the limited number of Australian farm ponds described in published literature. Littoral zones supported forty-five macroinvertebrate families, with most belonging to the orders Hemiptera, Coleoptera, Odonata, and Diptera. Invertebrate community composition was strongly influenced by littoral zone macrophyte structure, with significant differences between ponds with high macrophyte cover compared to those with bare littoral zones. The importance of littoral zone macrophytes was also suggested by a significant positive relationship between invertebrate taxonomic richness and macrophyte cover. The landowners in this study demonstrated sound ecological knowledge of their farm ponds, but many had not previously acknowledged them as having high habitat value for native flora and fauna. If managed for aquatic organisms as well as reliable water sources, these artificial habitats may help to maintain regional biodiversity, particularly given the large number of farm ponds

    Full Text Available Hyperspectral imaging is a powerful tool for mineral mapping and increasingly used in poorly-accessible areas. It only requires a limited amount of validation sample points, but can fail to discriminate spectrally-similar features. In this manuscript, we show that we improve the identification of interesting targets by including geomorphological data in the spectral mapping scheme. We jointly use geomorphic and spectral features to locate gossanous ironstone ridges as an indicator for possible Pb-Zn-Ag-mineralization and provide an application around Mount Isa and George Fisher/Hilton mine, Queensland, Australia. We combine hyperspectral HyMap data using mixture tuned matched filtering with topographical indices, such as maximum curvature and the topographical position index. As it is often the case with structurally-controlled mineralization, the amount of training sites is limited, and supervised classification methods cannot be implemented. Therefore, we implement expert knowledge in a decision tree to take advantage of the relationship between mineralization, alteration and structure. Optimized rock sampling and spectral measurements provided data for validation. We are able to map sets of gossanous ridges with a minimum of validation points, not only within the Mount Isa mining area itself, but also outside the commonly-accepted host rocks. The ridges are parallel to north-south trending geomorphological features and probably associated with the Paroo fault zone. Similarities between the ridges were confirmed by field observations, spectral measurements and a qualitative rock sample analysis. We identified new mineralized ridges that we could subsequently attribute to a poorly-known and sub-economic deposit known as the Mount Novit Pb-Zn-deposit.

    Municipal wastewaters contain a multitude of organic compounds derived from domestic and industrial sources including active components of pharmaceutical and personal care products and compounds used in agriculture, such as pesticides, or food processing such as artificial sweeteners often referred to as micropollutants. Some of these compounds or their degradation products may have detrimental effects on the environment, wildlife and humans. Acesuflame is one of the most popular artificial sweeteners to date used in foodstuffs. The main objectives of this descriptive study were to evaluate the presence of micropollutants in both the influent and effluent of a large-scale conventional biological wastewater treatment plant (WWTP) in South-East Queensland receiving wastewater from households, hospitals and various industries. Based on USEPA Method 1694: Filtered samples were spiked with mass-labelled chemical standards and then analysed for the micropollutants using liquid chromatography coupled with tandem mass spectrometry. The presence of thirty-eight compounds were detected in the wastewater influent to the treatment plant while nine of the compounds in the categories of analgesic, anti-inflammatory, alkaloid and lipid/cholesterol lowering drugs were undetectable (100 % removed) in the effluent. They were: Analgesic: Paracetamol, Salicylic acid, Oxycodone; Anti-inflammatory: Naproxen + ve, Atorvastatin, Indomethacin, Naproxen; Alkaloid: Caffeine; Lipid/cholesterol lowering: Gemfibrozol. The study results revealed that the micropollutants removal through this biological treatment process was similar to previous research reported from other countries including Europe the Americas and Asia, except for acesulfame, a highly persistent artificial sweetener. Surprisingly, acesulfame was diminished to a much greater extent (>90 %) than previously reported research for this type of WWTPs (45-65 %) that only include physical removal of objects and solids and a

    SummaryThis paper reports a comparison of measured and modelled interception for three different forest types at six rainforest locations in northern Queensland. The Gash interception model was able to reproduce cumulative interception at the sites accurately, provided an appropriate value of canopy storage capacity ( S) was used, 2.0-3.6 mm. These values are significantly higher than S values generally reported in other rainforest studies (˜1 mm) and the reason may be that Australian rainforests contain many epiphytes and mosses, which can trap significant quantities of water within the canopy. There is also some evidence of a seasonal variation in S and wet canopy evaporation rate ( E), both being lower in the dry season than the wet season. However, although the rainfall rate ( R), S and E all affect the seasonal value of interception, the changes in these three parameters tend to compensate and so the biggest factor affecting seasonal variations in interception is the number of small storms. The consequence of this is that it is still possible to get good estimates of seasonal and annual interception using R, S and E values that are fixed for the entire year. Values of E fell in the range 0.35-0.81 mm h -1, which are 1.4-9 times the concurrent rates estimated using the Penman-Monteith equation. This implies that either our rainforests received very large amounts of advected energy during rain storms, or the Penman-Monteith E values are too low. Some advection of energy to our sites is quite feasible given their proximity to the ocean and generally well exposed locations. However, most of the above discrepancy is probably due to underestimation of the Penman-Monteith values of E, because of errors in the estimation of the above canopy relative humidity, due to the use of weather data adjacent to rather than above the forests and inherent difficulties of measuring the very high humidity's that occur during rainfall.

    Simple Summary Microchip identification has become an important tool to reunite stray dogs and cats with their owners, and is now compulsory in most states of Australia. Improvement of the microchipping system in Australia is limited by a lack of published Australian data documenting the problems experienced by shelter staff when using microchip data to contact the owner of a stray animal. In this study we determine the character and frequency of inaccurate microchip data to identify weaknesses in the current microchipping system. This information could be used to develop strategies that increase the accuracy of microchip data that will increase the reclaiming of stray animals. Abstract A lack of published information documenting problems with the microchip data for the reclaiming of stray animals entering Australian shelters limits improvement of the current microchipping system. A retrospective study analysing admission data for stray, adult dogs (n = 7258) and cats (n = 6950) entering the Royal Society for the Prevention of Cruelty to Animals (RSPCA) Queensland between January 2012 and December 2013 was undertaken to determine the character and frequency of microchip data problems and their impact on outcome for the animal. Only 28% of dogs and 9% of cats were microchipped, and a substantial proportion (37%) had problems with their data, including being registered to a previous owner or organisation (47%), all phone numbers incorrect/disconnected (29%), and the microchip not registered (14%). A higher proportion of owners could be contacted when the microchip had no problems, compared to those with problems (dogs, 93% vs. 70%; cats, 75% vs. 41%). The proportion of animals reclaimed declined significantly between microchipped animals with no data problems, microchipped animals with data problems and non-microchipped animals—87%, 69%, and 37%, respectively, for dogs and 61%, 33%, and 5%, respectively, for cats. Strategies are needed to increase the accuracy of

    The present study explored the impact of random breath testing (RBT) on the attitudes, perceptions, and self-reported behavior of motorists in the Australian state of Queensland. Particular attention was given to how exposure to RBT impacted motorists' perceived risk of apprehension and self-reported behavior, relative to other variables of interest such as alcohol consumption. The study involved a telephone survey of 780 motorists drawn from throughout the state of Queensland. Participants were volunteers recruited from a random sample of all listed telephone numbers in the state, adjusted according to district population figures. The survey questionnaire collected information relating to the participants' socio-demographic characteristics, drinking and drunk driving behaviors, attitudes toward drunk driving and RBT, and experiences and perceptions of RBT. The analysis indicated that a large proportion of the sample had both observed RBT and been breath tested within the last six months and believed the practice served an important role in improving road safety. However, a considerable percentage also reported drunk driving at least once in the last six months without being detected, with further analysis indicating that the threat of apprehension associated with RBT did not appear to greatly influence their offending behavior. Rather, a higher frequency of alcohol consumption, combined with more favorable attitudes to drunk driving and lower levels of support for RBT, appeared to be associated with offending behavior. While the results confirm the high levels of exposure to RBT achieved in Queensland, the direct impact of recent exposure on drunk driving behavior appears less important than other factors such as alcohol consumption and attitudes to drunk driving and RBT. Further research is required to better understand how recent and lifetime exposure to RBT impacts on motorists' perceived risk of apprehension and subsequent drunk driving behavior.

    Pasture-based systems, dominated by the tussock forming Cenchrus cilliaris cv. Biloela (buffel grass) and the stoloniferous Chloris gayana cv. Pioneer (rhodes grass), are commonly used in the revegetation of lands disturbed by coal mining in the Bowen Basin of Central Queensland. Although able to establish quickly under favourable conditions, neither species has proven entirely suitable for use in this situation, particularly in providing effective ground cover for erosion control on the re-contoured post-mining landscape. The aim of this study was to evaluate a range of new pasture grasses, with the objective of identifying accessions better adapted to the climatic conditions of the areas requiring revegetation.

    Three strains (JCM 15063(T), JCM 15098 and JCM 15099) of a novel basidiomycetous yeast species belonging to the genus Sporobolomyces were isolated from nasal smears of Queensland koalas kept in a Japanese zoological park. Analyses of sequences of the nuclear rDNA internal transcribed spacer region and the 26S rDNA D1/D2 domain and morphological studies indicated that these strains represent a novel species with a close phylogenetic relationship to Sporobolomyces carnicolor and Sporobolomyces japonicus in the Sporidiobolus lineage, for which the name Sporobolomyces koalae sp. nov. is proposed (type strain JCM 15063(T) =CBS 10914(T) =DSM 19992(T)).

    Legionellae are frequent contaminants of potable water supplies, resulting in sporadic infections and occasional outbreaks. Isolates of Legionella were collected from urban test sites within South East Queensland and evaluated for their virulence potential in vitro. Two strains (from the species Legionella londiniensis and Legionella quinlivanii) were demonstrated to have the ability to infect human macrophages, while a strain from the species Legionella anisa did not maintain an infection over the same time course. This suggests that the spectrum of urban environmentally associated Legionella with potential to cause human disease might be greater than currently considered.

    Following the emergence of Hendra virus (HeV), private veterinarians have had to adopt additional infection control strategies to manage this zoonosis. Between 1994 and 2010, seven people became infected with HeV, four fatally. All infected people were at a higher risk of exposure from contact with horses as they were either veterinary personnel, assisting veterinarians, or working in the horse industry. The management of emerging zoonoses is best approached from a One Health perspective as it benefits biosecurity as well as a public health, including the health of those most at risk, in this case private veterinarians. In 2011 we conducted a cross-sectional study of private veterinarians registered in Queensland and providing veterinary services to horses. The aim of this study was to gauge if participants had adopted recommendations for improved infection control, including the use of personal protective equipment (PPE), and the development of HeV specific management strategies during the winter of 2011. A majority of participants worked in practices that had a formal HeV management plan, mostly based on the perusal of official guidelines and an HeV field kit. The use of PPE increased as the health status of an equine patient decreased, demonstrating that many participants evaluated the risk of exposure to HeV appropriately; while others remained at risk of HeV infection by not using the appropriate PPE even when attending a sick horse. This study took place after Biosecurity Queensland had sent a comprehensive package about HeV management to all private veterinarians working in Queensland. However, those who had previous HeV experience through the management of suspected cases or had attended a HeV specific professional education programme in the previous 12 months were more likely to use PPE than those who had not. This may indicate that for private veterinarians in Queensland personal experience and face-to-face professional education sessions may be more

    A male Queensland koala (Phascolarctos cinereus adustus) at Kanazawa Zoological Gardens (Kanagawa, Japan) exhibited paralytic symptoms in the hind limbs. Computed tomography and magnetic resonance imaging revealed a mass on the left ventral side of the 11th to 13th thoracic vertebrae, and the presence of myelitis or edema in the spinal cord. The koala was under anesthesia during the examination and suddenly developed ventricular fibrillation and died. Necropsy revealed a firm flat ovoid hemorrhagic mass on the vertebrae. Following a microscopic examination including immunohistochemistry, the perivertebral mass was diagnosed as B cell lymphoma. Therefore, neoplastic cell infiltration into the spinal cord may cause paralytic symptoms in the hind limbs.

    Full Text Available Abstract Background Cross national drug utilization studies can provide information about different influences on physician prescribing. This is important for medicines with issues around safety and quality of use, like non selective non-steroidal anti-inflammatory drugs (ns-NSAIDs and cyclo-oxygenase-2 (COX-2 inhibitors. To enable comparison of prescription medicine use across different jurisdictions with a range of population sizes, data first need to be compared within Australia to understand whether use in a smaller sub-population may be considered as representative of the total use within Australia. The aim of this study was to compare the utilization of non selective NSAID, COX-2 inhibitors and paracetamol between Queensland and Australia. Method Dispensing data were obtained for concession beneficiaries for Australia for ns-NSAIDs, COX-2 inhibitors and paracetamol subsidized by the PBS over the period 1997–2003. The same data were purchased for Queensland. Data were converted to Defined Daily Dose (DDD/1000 beneficiaries/day (World Health Organization anatomical therapeutic chemical classification, 2005. Results Total NSAID and paracetamol consumption were similar in Australia and Queensland. Ns-NSAID use decreased sharply with the introduction of COX-2 inhibitors (from approximately 80 to 40 DDD/1000 beneficiaries/day. Paracetamol was constant (approximately 45 DDD/1000 beneficiaries/day. COX-2 inhibitors consumption was initially higher in Queensland than in the whole of Australia. Conclusion Despite initial divergence in celecoxib use between Queensland and Australia, the use of ns-NSAIDs, COX-2 inhibitors and paracetamol overall, in concession beneficiaries, was comparable in Australia and Queensland.

    Full Text Available Worldwide, more than 40% of the population is at risk from dengue and recent estimates suggest that up to 390 million dengue infections are acquired every year. The Eliminate Dengue (ED Program is investigating the use of Wolbachia-infected, transmission-compromised, mosquitoes to reduce dengue transmission. Previous introductions of genetically-modified strategies for dengue vector control have generated controversy internationally by inadequately engaging host communities. Community Engagement (CE was a key component of the ED Program's initial open release trials in Queensland Australia. Their approach to CE was perceived as effective by the ED team's senior leadership, members of its CE team, and by its funders, but if and why this was the case was unclear. We conducted a qualitative case study of the ED Program's approach to CE to identify and critically examine its components, and to explain whether and how these efforts contributed to the support received by stakeholders.In-depth semi-structured interviews were conducted with 24 participants with a range of experiences and perspectives related to the ED Program's CE activities. Our analytic approach combined techniques of grounded theory and qualitative description. The ED Program's approach to CE reflected four foundational features: 1 enabling conditions; 2 leadership; 3 core commitments and guiding values; and 4 formative social science research. These foundations informed five key operational practices: 1 building the CE team; 2 integrating CE into management practices; 3 discerning the community of stakeholders; 4 establishing and maintaining a presence in the community; and 5 socializing the technology and research strategy. We also demonstrate how these practices contributed to stakeholders' willingness to support the trials.Our case study has identified, and explained the functional relationships among, the critical features of the ED Program's approach to CE.

    The popularity of moped and motor scooter riding in Australia is increasing. However, there is a paucity of information about their safety, especially in comparison to motorcycle riding where riders require specific licensing, education and training. Given it is widely established that motorcycle riders are overrepresented in road injury statistics, consideration of moped and scooter riders as a sub-group of all motorcyclists is required for accurate understanding of injury patterns and the acute care needs of this group. A comparison of demographic, injury and acute care characteristics between seriously injured moped/scooter riders and motorcycle riders was undertaken using data from the state-wide trauma registry in Queensland, Australia, from 2006 to 2010. A total of 206 moped/scooter riders and 2667 motorcycle riders were identified. Motorcycle rider injury admissions significantly decreased over time (pinjuries (+2.3%), whereas motorcycle riders sustained a greater percentage of upper extremity (+4.0%), thoracic (+3.9%), spinal (+3.6%) and lower extremity injuries (+2.6%). There was no statistically significant difference in injury severity, length of acute hospital stay, admission to ICU or survival to discharge from acute care between injured moped/scooter riders and motorcycle riders. The results of this study suggest that riders of mopeds/scooters and motorcycles may have different injury patterns, but sustain similar overall injury severity. This analysis fills a gap in transport crash data, where there is limited information on the nature of injuries sustained. While moped-related injuries cannot be isolated in ICD-10 health coding, it is anticipated that ICD-11, due for release in 2015, may provide a moped-specific code; however, this will not address the issue of the apparent interchangeable use of the terms 'moped' and 'scooter' when reporting or documenting such injuries in health data systems including the medical record.

    Coastal wetlands provide a wide variety of important ecosystem services but continue to suffer disturbance, degradation and deforestation. Sediment bacteria are responsible for major nutrient transformation and recycling in these ecosystems. Insight into microbial community composition and the factors that determine them may improve our understanding of biogeochemical processes, food web dynamics, biodegradation processes and, thus, help to develop the management strategies for preserving the ecosystem health and services. Characterizing shifts in community taxa along environmental gradients has been shown to provide a useful tool for determining the major drivers affecting community structure and function. North Stradbroke Island (NSI) in Southern Queensland presents considerable habitat diversity including variety of groundwater dependent ecosystems such as lakes, swamps, sedge-like salt marshes and mangroves. Ecological responses of continuous groundwater extraction for municipal purposes and sand mining operations on NSI are still need to be assessed in order to protect its unique environment. Changes in coastal hydrology due to either climate change or human activity may directly affect microbial populations and, thus, biogeochemical cycles of nutrients. These may result in altering/losing some ecosystem services provided by coastal wetlands. In this study we examine microbial diversity and determine environmental controls on bacterial community structure along a natural transition from freshwater forested wetland (melaleuca woodland), sedge-like salt marsh and into mangroves located at NSI. The study area is characterized by significant groundwater flow, nutrient limitation and sharp transition from one ecosystem type to another. Sediment cores (0-5 cm and 20-25 cm depth) were collected from three representative sites of each zone (mangroves - salt marsh - freshwater wetland) along the salinity gradient in August 2012. Subsamples were set aside for use in

    Full Text Available Time series of images are required to extract and separate information on vegetation change due to phenological cycles, inter-annual climatic variability, and long-term trends. While images from the Landsat Thematic Mapper (TM sensor have the spatial and spectral characteristics suited for mapping a range of vegetation structural and compositional properties, its 16-day revisit period combined with cloud cover problems and seasonally limited latitudinal range, limit the availability of images at intervals and durations suitable for time series analysis of vegetation in many parts of the world. Landsat Image Time Series (LITS is defined here as a sequence of Landsat TM images with observations from every 16 days for a five-year period, commencing on July 2003, for a Eucalyptus woodland area in Queensland, Australia. Synthetic Landsat TM images were created using the Spatial and Temporal Adaptive Reflectance Fusion Model (STARFM algorithm for all dates when images were either unavailable or too cloudy. This was done using cloud-free scenes and a MODIS Nadir BRDF Adjusted Reflectance (NBAR product. The ability of the LITS to measure attributes of vegetation phenology was examined by: (1 assessing the accuracy of predicted image-derived Foliage Projective Cover (FPC estimates using ground-measured values; and (2 comparing the LITS-generated normalized difference vegetation index (NDVI and MODIS NDVI (MOD13Q1 time series. The predicted image-derived FPC products (value ranges from 0 to 100% had an RMSE of 5.6. Comparison between vegetation phenology parameters estimated from LITS-generated NDVI and MODIS NDVI showed no significant difference in trend and less than 16 days (equal to the composite period of the MODIS data used difference in key seasonal parameters, including start and end of season in most of the cases. In comparison to similar published work, this paper tested the STARFM algorithm in a new (broadleaf forest environment and also

    The semi-arid Surat Basin in central Queensland, Australia, forms part of the Great Artesian Basin, a groundwater resource of national significance. While this area relies heavily on groundwater supply bores to sustain agricultural industries and rural life in general, measurement of groundwater extraction rates is very limited. Consequently, regional groundwater extraction rates are not well known, which may have implications for regional numerical groundwater modelling. However, flows from a small number of bores are metered, and less precise anecdotal estimates of extraction are increasingly available. There is also an increasing number of other spatiotemporal datasets which may help predict extraction rates (e.g. rainfall, temperature, soils, stocking rates etc.). These can be used to construct spatial multivariate regression models to estimate extraction. The data exhibit complicated statistical features, such as zero-valued observations, non-Gaussianity, and non-stationarity, which limit the use of many classical estimation techniques, such as kriging. As well, water extraction histories may exhibit temporal autocorrelation. To account for these features, we employ a separable space-time model to predict bore extraction rates using the R-INLA package for computationally efficient Bayesian inference. A joint approach is used to model both the probability (using a binomial likelihood) and magnitude (using a gamma likelihood) of extraction. The correlation between extraction rates in space and time is modelled using a Gaussian Markov Random Field (GMRF) with a Matérn spatial covariance function which can evolve over time according to an autoregressive model. To reduce computational burden, we allow the GMRF to be evaluated at a relatively coarse temporal resolution, while still allowing predictions to be made at arbitrarily small time scales. We describe the process of model selection and inference using an information criterion approach, and present some

    The Fitzroy River estuary is a macrotidal, tide-dominated estuary located in the dry tropics of central Queensland, and represents the major source of terrestrial sediment to the southern Great Barrier Reef (GBR) lagoon. The estuary currently receives most of its sediment during large episodic floods that are typically associated with cyclones. Mean annual sediment budgets for such systems are difficult to estimate due to the sporadic nature of flood discharge events, which are highly seasonal and vary greatly in magnitude between years. We have estimated the quantity and long-term rate of accumulation of catchment-derived sediment in the estuarine floodplain using the Holocene stratigraphic sequence determined from a series of sediment cores, dated with radiocarbon and optically stimulated luminescence (OSL) methods. Approximately 13,760 million tonnes (Mt) of fluvial sediment has accumulated in the Fitzroy estuary during the past 8000 years, which equates to an average of 1720 kt yr - 1 . Over the past 100 years, sediment accumulation has been focused around mangrove and tidal creek environments, which cover an area of 130 km 2. Cores from the tidal creeks, dated using 137Cs, 210Pb, and OSL, provide sedimentation rates of approximately 15 mm yr - 1 for the past 45-120 years, or sediment mass accumulation of 1700 kt yr - 1 , which includes a component that is reworked into the estuary by tidal currents. Combined with the small amount of sediment that accumulates on the floodplain during floods (˜ 1 mm yr - 1 , 640 kt yr - 1 ), we estimate that approximately 2350 kt yr - 1 of sediment is trapped in the modern lower floodplain and estuary. This estimate of sediment storage suggests that greater than 50% of the modern mean annual sediment discharge of the Fitzroy River, 4162 kt yr - 1 , may be retained in the lower floodplain and estuary. These results provide useful insights into the spatial pattern of sedimentation, long-term rates of accumulation and estimates of

    Wastewater analysis, or wastewater-based epidemiology, has become a common tool to monitor trends of illicit drug consumption around the world. In this study, we examined trends in cocaine, 3,4-methylenedioxymethamphetamine (MDMA) and methamphetamine consumption by measuring their residues in wastewater from two wastewater treatment plants in Australia (specifically, an urban and a rural catchment, both in South East Queensland) between 2009 and 2015. With direct injection of the samples, target analytes were identified and quantified using liquid chromatography-mass spectrometry. Cocaine and MDMA residues and metabolites were mainly quantifiable in the urban catchment while methamphetamine residues were consistently detected in both urban and rural catchments. There was no consistent trend in the population normalised mass loads observed for cocaine and MDMA at the urban site between 2009 and 2015. In contrast, there was a five-fold increase in methamphetamine consumption over this period in this catchment. For methamphetamine consumption, the rural area showed a very similar trend as the urban catchment starting at a lower baseline. The observed increase in per capita loads of methamphetamine via wastewater analysis over the past six years in South East Queensland provides objective evidence for increased methamphetamine consumption in the Australian population while the use of other illicit stimulants remained relatively stable.

    The rate of alcohol-related emergency department (ED) presentations in young people has increased dramatically in recent decades. Injuries are the most common type of youth alcohol-related ED presentation, yet little is known about these injuries in young people. This paper describes the characteristics of alcohol-related ED injury presentations in young people over a 13-year period and determines if they differ by gender and/or age group (adolescents: 12-17 years; young adults: 18-24 years). The Queensland Injury Surveillance Unit (QISU) database collects injury surveillance data at triage in participating EDs throughout Queensland, Australia. A total of 4667 cases of alcohol-related injuries in young people (aged 12-24 years) were identified in the QISU database between January 1999 and December 2011, using an injury surveillance code and nursing triage text-based search strategy. Overall, young people accounted for 38% of all QISU alcohol-related ED injury presentations in patients aged 12 years or over. The majority of young adults presented with injuries due to violence and falls, whereas adolescents presented due to self-harm or intoxication without other injury. Males presented with injuries due to violence, whereas females presented with alcohol-related self-harm and intoxication. There is a need for more effective ways of identifying the degree of alcohol involvement in injuries among young people presenting to EDs. © 2014 Australasian Professional Society on Alcohol and other Drugs.

  15. The role of integrative taxonomy in the conservation management of cryptic species: the taxonomic status of endangered earless dragons (Agamidae: Tympanocryptis in the grasslands of Queensland, Australia.

    Jane Melville

    Full Text Available Molecular phylogenetics is increasingly highlighting the prevalence of cryptic species, where morphologically similar organisms have long independent evolutionary histories. When such cryptic species are known to be declining in numbers and are at risk of extinction due to a range of threatening processes, the disjunction between molecular systematics research and conservation policy becomes a significant problem. We investigate the taxonomic status of Tympanocryptis populations in Queensland, which have previously been assigned to T. tetraporophora, using three species delimitation approaches. The taxonomic uncertainties in this species-group are of particular importance in the Darling Downs Earless Dragon (T. cf. tetraporophora, which is ranked as an endangered 'species' of high priority for conservation by the Queensland Department of Environment and Heritage Protection. We undertook a morphological study, integrated with a comprehensive genetic study and species delimitation analyses, to investigate the species status of populations in the region. Phylogenetic analyses of two gene regions (mtDNA: ND2; nuclear: RAG1 revealed high levels of genetic divergence between populations, indicating isolation over long evolutionary time frames, and strongly supporting two independent evolutionary lineages in southeastern Queensland, from the Darling Downs, and a third in the Gulf Region of northern Queensland. Of the three species delimitation protocols used, we found integrative taxonomy the most applicable to this cryptic species complex. Our study demonstrates the utility of integrative taxonomy as a species delimitation approach in cryptic complexes of species with conservation significance, where limited numbers of specimens are available.

    Decision makers in the water sector need to deal with existing hydroclimatic variability and uncertainty about future changes to climate and catchment conditions. Identifying solutions for hydroclimatic risk adaptation strategies that are both optimal and robust in the presence of variability and uncertainty presents a difficult challenge. A major reason for this challenge is the fact that the instrumental record in Australia is short ( 60-130 years) and fails to encompass enough climate variability to allow the calculation of robust statistics around the baseline risk of extreme events (e.g. multi-year droughts, decadal periods with clustering of major flood events). This climate variability is documented pre-1900 in palaeoclimate records from sources such as corals, tree-rings, freshwater and marine sediments. Despite being remote from Queensland, a high resolution and highly correlated palaeoclimate record from the Law Dome ice cores in Antarctica (Vance et al. 2015) is also now available and has identified eight mega-droughts (lasting from 5-39 years) during 1000-2009 AD. Most importantly, the palaeoclimate information confirms that the post-1900 instrumental period (i.e. the period on which all water resources infrastructure, policy, operation rules and strategies is based) does not capture the full range of variability that has occurred. Other work also clearly shows that, out to 2050 at least, impacts associated with natural variability significantly exceed even the worst-case climate change scenarios (i.e. obtained from Global Climate Models run under the highest emission scenarios). This presentation will demonstrate how the Law Dome ice cores from Antarctica have been used to produce a highly accurate, 1000 year, annual and seasonal resolution, hydroclimate reconstruction (i.e. precipitation and streamflow) for the southeast Queensland region of Australia. We will then show how the palaeoclimate data has been incorporated into the South East Queensland

    To examine the potential impact of climate variability on the transmission of Ross River virus (RRv) infection, and to assess the difference in the potential predictors of RRv incidence in coastline and inland regions, Queensland, Australia. Information on the RRv cases notified between 1985 to 1996 was obtained from the Queensland Department of Health. Climate and population data were supplied by the Australian Bureau of Meteorology and the Australia Bureau of Statistics, respectively. The function of cross correlations was used to compute a series of correlations between climate variables (rainfall, maximum temperature, minimum temperature, relative humidity, and high tide) and the monthly incidence of RRv disease over a range of time lags. Time series Poisson regression models were performed to adjust for the autocorrelations of the monthly incidences of RRv disease and the confounding effects of seasonality, the case notification time, and population sizes. The cross correlation function shows rainfall, maximum temperature, minimum temperature, and relative humidity at a lag of 1-2 months and high tide in the current month were significantly associated with the monthly incidence of RRv in the coastline region. Relative humidity and rainfall at a lag of two months was also significantly associated with the monthly incidence of RRv in the inland region. The results of Poisson regressive models show that the incidence of RRv disease was significantly associated with rainfall, maximum temperature, minimum temperature, relative humidity, and high tide in the coastline region, and with rainfall and relative humidity in the inland region. There was a significant interaction between climate variables and locality in RRv transmission. Climate variability may have played a significant role in the transmission of RRv. There appeared to be different responses of RRv to climate variability between coastline and inland cities in Queensland, Australia. Maximum temperature

    Full Text Available As a cross-disciplinary field, the risk communication (RC discourse is complex. Thereof, media coverage of disasters as a fundamental resource of RC should be examined to guarantee successful delivery of risk information. Thus, this study investigated the content of risk information of cyclone-related news of the Brisbane Times and The Australian newspapers. It scrutinized the different types of risk-related messages by means of a quantitative content analysis based on the Extended Parallel Processing Model (EPPM proposed by Witte (1980. The media coverage of the 2011 Queensland cyclones was examined with respect to the main question: what type of risk information the public was provided with? It was shown that the coverage of the Brisbane Times and The Australian might be enhanced by covering main components equally, focusing more on the component of efficacy, specifically ‘the outcomes of preventive actions’.

    Micrometeorological and microplot experiments were conducted in the field of freshly harvested green cane in Queensland,Australia.Results showed that high ammonia loss of fertilizer N could occur under relatively dry conditions when urea or commercial product of mixture of urea and muriate of potash were applied to the surface of sugarcane trash.The moisture content in the trash and the pH of fertilizer were two important factors controlling the processes of urea hydrolysis and ammonia volatilization.Most of the N in the soil was transformed to the nitratel-nitrite from after 70 days of fertilizer application.No significant leaching was found.Urea-free N fertilizers had higher N recoveries compared to urea-containing fertilizers.

  20. An empirical model of water quality for use in rapid management strategy evaluation in Southeast Queensland, Australia.

    2012-04-01

    Simulation models have been widely adopted in fisheries for management strategy evaluation (MSE). However, in catchment management of water quality, MSE is hampered by the complexity of both decision space and the hydrological process models. Empirical models based on monitoring data provide a feasible alternative to process models; they run much faster and, by conditioning on data, they can simulate realistic responses to management actions. Using 10 years of water quality indicators from Queensland, Australia, we built an empirical model suitable for rapid MSE that reproduces the water quality variables' mean and covariance structure, adjusts the expected indicators through local management effects, and propagates effects downstream by capturing inter-site regression relationships. Empirical models enable managers to search the space of possible strategies using rapid assessment. They provide not only realistic responses in water quality indicators but also variability in those indicators, allowing managers to assess strategies in an uncertain world.

    2004-05-01

    Full Text Available This paper analyses the general trends of online purchasing in Central Queensland (CQ communities during 1999-2002 and identifies the socio-economic factors affecting online purchasing activities. The Online Purchasing Indicator, defined as a combination of percentages of online purchasers and of regular purchasers (>one item/month within a group, is applied to compare these activities between these two groups. The study identifies that four factors, namely ‘personal attributes’, ‘knowledge’, ‘trust’ and ‘need’ may play important roles in online purchasing decisions. The research found that regional economic bleeding associated with low local adoption failing to provide justification for local business to adopt electronic purchasing support has not yet reached significant levels.

    Full Text Available A new species of the genus Tasmanitachoides Erwin from North Queensland is described: T. glabellus n. sp. The species belongs to the T. murrumbidgensis¿group of species that is characterized by its distinctly impressed clypeus, but it is distinguished from all related species by its glabrous body surface. It is the first Tasmanitachoides from northern Australia to be found in rainforest on high mountains and has thus probably preserved the original habits of the genus that are still characteristic for those species living in southern temperate regions of Australia. Tasmanitachoides lutus (Darlington so far known from the type locality in southern New South Wales and from the holotype only, is now recorded from eastern Victoria.

    In Australia, dengue is not endemic, although the vector mosquito Aedes aegypti is established in far north Queensland (FNQ). Aedes albopictus has recently invaded the Torres Strait region, but is not established on mainland Australia. To maintain dengue-free, public health departments in FNQ closely monitor introduced dengue infections and confine outbreaks through rigorous vector control responses. To safeguard mainland Australia from Ae. albopictus establishment, pre-emptive strategies are required to reduce its breeding in difficult to access habitats. We compare the residual efficacy of VectoBac WDG, Bacillus thuringiensis var. israelensis (Bti) formulation, as a residual treatment when misted across a typical FNQ bushland using a backpack mister (Stihl SR 420 Mist Blower) at two dose rates up to 16 m. Semi-field condition results, over 16 weeks, indicate that Bti provided high mortality rates (> 80%) sustained for 11 weeks. Mist application penetrated 16 m of dense bushland without efficacy decline over distance.

    2013-01-01

    Following the discovery of a new population of Phyllurus ossa on Whitsunday Island in the Cumberland Island Group, eastern Queensland, we conducted both genetic and morphological analyses to assess differences between all known populations. The analyses revealed three genetically distinct, morphologically diagnosable, geographical units. The differences are such that we recognise these as subspecies: Phyllurus ossa ossa restricted to the Mt Ossa/Mt Pelion/ Mt Charlton/ St Helens Gap area; P. ossa hobsoni subsp. nov. on Mt Dryander and in the Conway Range and P. ossa tamoya subsp. nov. currently only known from Whitsunday Island. There are now 11 recognised taxa in Phyllurus. The three P. ossa subspecies are narrowly distributed and closely associated with exposed rock in low to mid-elevation vine forests. Their current distributions are shaped by past climate change that progressively contracted and fragmented the distribution of rainforests in eastern Australia. The recognition of these subspecies has land management/conservation implications.

    Tropical seagrass decline and recovery from severe storm impacts was assessed via quarterly measurements of seagrass biomass, species composition and experimental investigations of recovery in north Queensland. Shallow and deep seagrass meadows suffered major declines. Significant recovery in the two years following loss only occurred at deeper sites. Halophila spp. in deep water areas had a high capacity for recovery through the availability of seed banks. In contrast, the shallow species did not recover quickly from experimental disturbance, had poor seed reserves and relied on asexual propagation. The potential for shallow species to recover rapidly from widespread losses was limited as seed banks were limited or non-existent. Understanding inter- and intra-specific differences in seagrass recovery and how this interacts with location is critical to predict the consequences of climate events to tropical seagrasses. This is especially important as more frequent severe storms are predicted as a consequence of climate change.

    During 2015 and 2014, nearly 60 km of high-resolution ground penetrating radar data were acquired on the Cooloola Sand Mass (CSM) in southeastern coastal Queensland. The CSM is part of the world's largest downdrift sand system. It contains three of the world's largest sand islands, several National Parks, a UNESCO World Heritage Site and covers 500 km of the eastern Australian coastline in northern New South Wales and southern Queensland. The large (>200 m) composite dunes of the CSM exhibit multiple activation phases, coastally eroding bluffs and dune development is not obvious from surficial exposures. This provides an ideal environment for ground penetrating radar. The dune sequences have been provisionally dated to the mid Quaternary through present and represent the potential for a large palaeo-environmental proxy dataset. GPR imagery was collected using a MALA GeoSciences Ground Explorer (GX) system with 160 and 450 MHz antennae from the numerous physiographic and ecological provinces as well as mapped surficial soil units at the CSM. These data were used to determine the subsurface architecture, identify radar facies and develop environmental interpretations. In the clean, aeolian quartz-rich sands, radar wave penetration exceeded 30 m (radar velocity = 0.07 m/ns) with the 160 MHz antenna. From the interpreted environmental units including palaeosol, dune slip face, dune stoss face, sand blow, beach, estuarine and fluvial, we are developing maps to relate the units and focus a detailed sampling regime that includes OSL, sediment geochemistry and sedimentology, The interpreted units, stratigraphic correlation and spatial distribution of the facies is the first step in a broader project to unravel the Quaternary environmental and climate records that are archived within the sediments of the CSM.

    Coal excavation and refinement processes generate substantial volumes of contaminated effluent that may be detrimental to aquatic ecosystems. As such, understanding the impacts of coal mine water releases on aquatic animals and ecosystems is essential for effectively managing and protecting neighboring environments. Such information will ultimately be applied towards developing ongoing monitoring strategies that are protective of native wildlife. Despite intensive mining operations in Australia, few studies have documented toxicity associated with coal mine wastewater (CMW) on native species. To address existing knowledge gaps, we investigated acute toxicity (48-96h) using eight native invertebrate species and sub-chronic effects (2 week) using three vertebrate species following exposure to wastewater from two dams (CMW1 and CMW2) located at an open-cut coal mine licensed to discharge into the Fitzroy catchment (Queensland, Australia). Wastewater from these sites is characterized by elevated conductivity, pH, sulfates as well as relatively high total and dissolved metal(loid)s (including As, Al, B, Cu, Mn, Ni, Se and Zn). Acute exposures revealed cladocerans (Daphnia carinata) and planarians (Dugesia sp.) to be the most sensitive species, exhibiting significant mortality after 48 and 96h exposure to CMW2, respectively. Neither wastewater was found to elicit acute toxicity in vertebrates, but a range of sub-lethal morphological effects were observed following the sub-chronic exposures. The overall response pattern was characterized by decreased condition factor and hepatosomatic index in the fish Hypseleotris compressa and Pseudomugil signifier, and in Limnodynastes peronii tadpoles. Tadpoles were generally more sensitive compared to the two fish species. Differences in responses were observed amongst CMW1 and CMW2, which likely relates to differences in physico-chemical properties between sites. Our results have identified several candidate vertebrate and

    Sexual orientation is seldom recorded at death in Australia, and to date there have been no studies on the relationship between those that have died by suicide and sexuality or minority gender identity in Australia. The aim of the present study is to determine whether or not lesbian, gay, bisexual, transgender (LGBT), and intersex individuals who die by suicide constitute a unique subpopulation of those who die by suicide, when compared with non-lesbian, gay, bisexual, transgender, and intersex suicide deaths. The Queensland Suicide Register holds records of all suicides in Queensland since 1990. All cases from 2000 to 2009 (inclusive; a total of 5,966 cases) were checked for potential indicators of individuals' sexual orientation and gender identification. A total of 35 lesbian (n = 10), gay (n = 22), bisexual (n = 2), and transgender (n = 1) suicide cases were identified. Three comparison cases of non-LGBT suicides for each LGBT suicide were then located, matched by age and gender. Conditional logistic regression was used to calculate odds ratios with 95% confidence intervals. It was significantly more likely that depression was mentioned in the cases of LGBT suicides than in non-LGBT cases. While 12.4% of the comparison group had been diagnosed with psychotic disorders, there were no such diagnoses among LGBT individuals. LGBT individuals experienced relationship problems more often, with relationship conflict also being more frequent than in non-LGBT cases. Despite its limitations, this study - the first of its kind in Australia - seems to indicate that LGBT people would require targeted approaches in mental and general health services. © 2014 Wiley Publishing Asia Pty Ltd.

    2015-12-10

    To document albuminuria prevalence and its associated factors in Aboriginal and Torres Strait Islander (TSI) adults with high renal and metabolic risks from 19 rural and remote north Queensland communities. One thousand nine hundred seventy-one indigenous adults were enrolled in 1998 and 566 completed follow up in 2007 in this population-based study. Measurements included weight, waist circumference (WC), blood pressure (BP), fasting glucose, lipids, gamma-glutamyltransferase (GGT), urinary albumin creatinine ratio (UACR), smoking, alcohol intake and physical activity (PA). Albuminuria was defined as an UACR > =2.5 g/mol in males and > =3.5 g/mol in females. The association between albuminuria and biomedical factors was assessed with generalised linear modelling. Baseline albuminuria prevalence was 19.7 % (95 % CI: 18.0-21.6 %). Follow up prevalence was 42.4 % (95 % CI: 38.4-46.5 %) among the 566 adults having the 2(nd) UACR measurements. Follow-up albuminuria was associated with fasting glucose of 5.4 mmol/L (OR 2.5, 95 % CI 1.5-4.2), GGT tertiles in a dose-response manner (OR 2.0 for 2(nd) and 3.7 for 3(rd) tertile, p for trend TSI counterparts, while TSI smokers had twice the likelihood (95 % CI 1.2-3.2). At both baseline and follow up, albuminuria was more prevalent among older participants. Indigenous Australians in north Queensland are at high risk of albuminuria. Overweight and obesity, glycaemia, increased GGT, and smoking were associated with albuminuria at baseline and/or follow up.

    The current Australian National Cervical Screening Program (NCSP) involves biennial, cytology-based screening of women from the age of 18 years. From December, 2017 this will change to a five-yearly human papilloma virus-based screening commencing at age 25. There is some concern that the new program may delay the opportunistic detection of cervical cancers in women under 25 years. (1) To review all cases of invasive cervical cancer in Queensland women under the age of 25 over the last 28 years. (2) To determine symptoms and screening history prior to diagnosis. A retrospective cohort study was undertaken at the Queensland Centre for Gynaecological Cancer (QCGC) and the Queensland Cancer Registry (QCR) of all women aged between 13 and 25 years diagnosed with cervical cancer in Queensland between 1984 and 2012. Demographic data and symptoms prior to diagnosis were extracted from the QCGC and QCR databases. A total of 56 women aged 13-25, were diagnosed with cervical cancer and treated at the QCGC between 1984 and 2012. The commonest reason for the diagnosis of cancer was investigation of abnormal symptoms (n = 22, 39%) rather than routine Pap smear abnormalities (n = 15, 26%). Consistent with the world literature, there is a very low incidence of cervical cancer in women under 25 years of age, irrespective of the age of commencement of screening, or the screening interval. Our study lends some support to the proposed commencement age of 25 years in the new NCSP. © 2017 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Open-cut coal mining in Central Queensland involves the breaking up of overburden that overlies the coal seams using explosives, followed by removal with draglines which results in the formation of extensive overburden spoil-piles with steep slopes at the angle of repose (approximately 75 % or 37o). These spoil-piles are found in long multiple rows, with heights of up to 60 or 70 m above the original landscapes. They are generally highly saline and dispersive and hence highly erosive. Legislation requires that these spoil-piles be rehabilitated into a stable self sustaining ecosystem with no off-site pollution. The first stage in the rehabilitation of these landscapes is the lowering of slopes to create a landscape that is stable against geotechnical failure and erosion. This is followed by revegetation generally with grasses as pioneer vegetation to further reduce erosion and a mixture of native shrubs and trees. Minimizing erosion and excessive on-site discharges of sediment into the working areas may result in the temporary cessation of mining operation with significant financial consequences, while off site discharges may breach the mining lease conditions. The average cost of rehabilitation is around 22,000 per ha. With more than 50,000 ha of such spoil-piles in Queensland at present, the total cost of rehabilitation facing the industry is very high. Most of this comprised the cost of reshaping the landscape, largely associated with the amount of material movement necessary to achieve the desired landscape. Since soil and spoil-piles vary greatly in their erodibilities, a reliable and accurate method is required to determine a cost effective combination of slope length, slope gradient and vegetation that will result in acceptable rates of erosion. A user friendly hillslope computer package MINErosion 3, was developed to predict potential erosion to select suitable combinations of landscape design parameters (slope gradient, slope length and vegetation cover

    Radiation dose to patients undergoing invasive coronary angiography (ICA) is relatively high. Guidelines suggest that a local benchmark or diagnostic reference level (DRL) be established for these procedures. This study sought to create a DRL for ICA procedures in Queensland public hospitals. Data were collected for all Cardiac Catheter Laboratories in Queensland public hospitals. Data were collected for diagnostic coronary angiography (CA) and single-vessel percutaneous intervention (PCI) procedures. Dose area product (P{sub KA}), skin surface entrance dose (K{sub AR}), fluoroscopy time (FT), and patient height and weight were collected for 3 months. The DRL was set from the 75th percentile of the P{sub KA.} 2590 patients were included in the CA group where the median FT was 3.5 min (inter-quartile range = 2.3–6.1). Median K{sub AR} = 581 mGy (374–876). Median P{sub KA} = 3908 uGym{sup 2} (2489–5865) DRL = 5865 uGym{sup 2}. 947 patients were included in the PCI group where median FT was 11.2 min (7.7–17.4). Median K{sub AR} = 1501 mGy (928–2224). Median P{sub KA} = 8736 uGym{sup 2} (5449–12,900) DRL = 12,900 uGym{sup 2}. This study established a benchmark for radiation dose for diagnostic and interventional coronary angiography in Queensland public facilities.

    Collaboration between dental practitioners and non-dental primary care providers has the potential to improve oral health care for people in rural and remote communities, where access to oral health services is limited. However, there is limited research on collaboration between these professional disciplines. The purpose of this paper was to explore the relationships between dental practitioners and non-dental primary care providers from rural and remote areas of Queensland and to identify strategies that could improve collaboration between these disciplines from the perspective of dental participants. Semi-structured interviews were conducted between 2013 and 2015 with visiting, local and regional dental practitioners (n = 12) who had provided dental services to patients from eight rural and remote Queensland communities that did not have a resident dentist. Participants were purposely recruited through a snow ball sampling technique. Interview data were analysed using thematic analysis with the assistance of QSR Nvivo v.10. Four major themes emerged from the data: (1) Communication between dental practitioners and rural primary care providers; (2) Relationships between dental and primary care providers; (3) Maintenance of professional dualism; (4) Strategies to improve interprofessional relationships (with subthemes: face to face meetings; utilisation of technology; oral health training for primary care providers; and having a community based oral health contact person). Participants observed that there was a lack of communication between the dental providers who saw patients from these rural communities and the primary care providers who worked in each community. This was attributed to poor communication, the high turnover of staff and the siloed behaviours of some practitioners. Visiting dental practitioners were likely to have stronger professional relationships with hospital nursing, administrative and allied health care staff who were often long term

    Lethal ovitraps (LOs) containing an insecticide-treated ovistrip are used as a lure-and-kill device for the container-breeding dengue vector, Aedes aegypti (L.). We aimed to affirm that the pyrethroid bifenthrin could be used effectively in LOs against Ae. aegypti in north Queensland, Australia, by quantifying oviposition in and mortality caused by LOs. Small cage experiments in which individual gravid Ae. aegypti were given a choice of LOs and untreated ovitraps revealed that although LOs were less acceptable for oviposition, they provided an average 64.6% adjusted mortality. Although 92% of mosquitoes ovipositing in LOs died, 61.8% of mosquitoes that visited but did not oviposit in an LO also died, demonstrating that lethal contact occurred without egg laying. The bifenthrin content of strips (approximately 0.1 mg/cm2; 7 mg/strip) did not decrease significantly after 4 wk of field exposure nor did the toxic effect of the LOs. Large cage trials with groups of 10 Ae. aegypti confirmed that bifenthrin-treated LOs provided consistent control (average adjusted mortality 79.7%). Four-week field trials in north Queensland showed that although LOs were acceptable to ovipositing Ae. aegypti (mean time to first egg 10.9 d; mean eggs 47.3), insecticide-free ovitraps were oviposited in more readily (6.8 d, 199 eggs). The number of eggs laid per mosquito in laboratory LOs allowed calculation of the number of Ae. aegypti killed in field-deployed LOs; rapid estimates can be made by simply dividing the number of eggs on the strip by 2.84. Overall, the studies demonstrated that bifenthrin-treated LOs have potential for use as a lure-and-kill device against Ae. aegypti and that they should be effective in the field for at least 4 wk. Given that untreated ovitraps were more acceptable for Ae. aegypti oviposition, the removal of alternative oviposition sites before deployment of LOs in the field should maximize their effectiveness.

    Koala populations are in catastrophic decline in certain eastern Australian regions. Spanning from 1997–2013, a database derived from wildlife hospitals in southeast Queensland with N = 20,250 entries was classified by causes of morbidity and mortality. A total of 11 aetiologies were identified, with chlamydiosis, trauma, and wasting being most common. The clinical diagnosis at submission varied significantly over the observation period. Combinations of aetiologies were observed in 39% of koalas submitted, with chlamydiosis frequently co-occurring. Urogenital (cystitis 26.8%, bursitis 13.5%) and ocular (conjunctivitis 17.2%) chlamydiosis were the most frequently diagnosed representations of the infection. Approximately 26% of submissions comprised koalas involved in vehicle accidents that were otherwise healthy. Age and sex of the koala as well as season and submission period were compared for the case outcomes of ‘dead on arrival’, ‘euthanized’, or ‘released’ for the four most common clinical diagnoses using multinomial logistic regression models. Exploratory space-time permutation scans were performed and overlapping space-time clusters for chlamydiosis, motor vehicle traumas and wasting unveiled high risk areas for koala disease and injury. Our results suggest that these aetiologies are acting jointly as multifactorial determinants for the continuing decline of koalas.

    Full Text Available Abstract Background Strategies for cancer reduction and management are targeted at both individual and area levels. Area-level strategies require careful understanding of geographic differences in cancer incidence, in particular the association with factors such as socioeconomic status, ethnicity and accessibility. This study aimed to identify the complex interplay of area-level factors associated with high area-specific incidence of Australian priority cancers using a classification and regression tree (CART approach. Methods Area-specific smoothed standardised incidence ratios were estimated for priority-area cancers across 478 statistical local areas in Queensland, Australia (1998-2007, n = 186,075. For those cancers with significant spatial variation, CART models were used to identify whether area-level accessibility, socioeconomic status and ethnicity were associated with high area-specific incidence. Results The accessibility of a person's residence had the most consistent association with the risk of cancer diagnosis across the specific cancers. Many cancers were likely to have high incidence in more urban areas, although male lung cancer and cervical cancer tended to have high incidence in more remote areas. The impact of socioeconomic status and ethnicity on these associations differed by type of cancer. Conclusions These results highlight the complex interactions between accessibility, socioeconomic status and ethnicity in determining cancer incidence risk.

    Despite significant progress, road trauma continues to represent a global safety issue. In Queensland (Qld), Australia, there is currently a focus on preventing the 'fatal five' behaviours underpinning road trauma (drug and drink driving, distraction, seat belt wearing, speeding, and fatigue), along with an emphasis on a shared responsibility for road safety that spans road users, vehicle manufacturers, designers, policy makers etc. The aim of this article is to clarify who shares the responsibility for road safety in Qld and to determine what control measures are enacted to prevent the fatal five behaviours. This is achieved through the presentation of a control structure model that depicts the actors and organisations within the Qld road transport system along with the control and feedback relationships that exist between them. Validated through a Delphi study, the model shows a diverse set of actors and organisations who share the responsibility for road safety that goes beyond those discussed in road safety policies and strategies. The analysis also shows that, compared to other safety critical domains, there are less formal control structures in road transport and that opportunities exist to add new controls and strengthen existing ones. Relationships that influence rather than control are also prominent. Finally, when compared to other safety critical domains, the strength of road safety controls is brought into question.

    This study demonstrates the importance of the conceptual hydrogeological model for the estimation of groundwater recharge rates in an alluvial system interconnected with an ephemeral or intermittent stream in south-east Queensland, Australia. The losing/gaining condition of these streams is typically subject to temporal and spatial variability, and knowledge of these hydrological processes is critical for the interpretation of recharge estimates. Recharge rate estimates of 76-182 mm/year were determined using the water budget method. The water budget method provides useful broad approximations of recharge and discharge fluxes. The chloride mass balance (CMB) method and the tritium method were used on 17 and 13 sites respectively, yielding recharge rates of 1-43 mm/year (CMB) and 4-553 mm/year (tritium method). However, the conceptual hydrogeological model confirms that the results from the CMB method at some sites are not applicable in this setting because of overland flow and channel leakage. The tritium method was appropriate here and could be applied to other alluvial systems, provided that channel leakage and diffuse infiltration of rainfall can be accurately estimated. The water-table fluctuation (WTF) method was also applied to data from 16 bores; recharge estimates ranged from 0 to 721 mm/year. The WTF method was not suitable where bank storage processes occurred.

    There is mounting evidence of systematic abuses, including torture, rape and extrajudicial killings directed against independence activists as well as the civilian population in Indonesian occupied West Papua. Refugees from West Papua have sought safety in neighbouring Australia, experiencing hazardous journeys during their flight. We report early observations from a mental health study among West Papuan refugees living in North Queensland, Australia. The project includes qualitative methods aimed at gathering histories of trauma and human rights violations as well as standard mental health assessments and indices of acculturation and resettlement stresses. We consider the emerging data from the vantage point of the Adaptation and Development After Persecution and Trauma model that identifies five psychosocial domains that require repair following exposure to gross human rights violations and refugee trauma. The model emphasizes the inter-relatedness of key challenges, the compounding of adversity, and the bivalent effects of complex experiences, with both positive and negative elements shaping the adaptive trajectory of displaced persons. Refugee groups have their own approaches to conceptualizing the complexity of their problems, with the term dua sakit representing the expression used by West Papuans to identify the multiple challenges they face. The study highlights the importance of assessing each refugee group within its unique social and cultural context, taking into account such diverse factors as geographical location, employment, and ongoing conflict in the homeland in designing appropriate interventions.

    The Queensland fruit fly, Bactrocera tryoni (Froggatt) (Q-fly), is a major horticultural pest in Eastern Australia. Effective monitoring, male annihilation technique (MAT) and mass trapping (MT) are all important for control and require strong lures to attract flies to traps or toxicants. Lure strength is thought to be related in part to volatility, but little vapour pressure data are available for most Q-fly lures. Raspberry ketone (4-(4-hydroxyphenyl)-2-butanone) and analogs that had esters (acetyl, difluoroacetyl, trifluoroacetyl, formyl, propionyl) and ethers (methyl ether, trimethylsilyl ether) in replacement of the phenolic group, and in one case also had modification of the 2-butanone side chain, were measured for their vapour pressures by differential scanning calorimetry (DSC), and their attractiveness to Q-fly was assessed in small cage environmentally controlled laboratory bioassays. Maximum response of one category of compounds, containing both 2-butanone side chain and ester group was found to be higher than that of the other group of compounds, of which either of 2-butanone or ester functionality was modified. However, linear relationship between vapour pressure and maximum response was not significant. The results of this study indicate that, while volatility may be a factor in lure effectiveness, molecular structure is the dominating factor for the series of molecules investigated.

  3. Suitability of macrophytes for nutrient removal from surface flow constructed wetlands receiving secondary treated sewage effluent in Queensland, Australia.

    From a botanical perspective the major difference between waste stabilisation ponds and wetlands is the dominance of algae or floating plants in the former and emergent plants in the latter. Algae, floating and submerged plants remove nutrients directly from the water column whereas emergent species remove nutrients from the sediment. Water depth is a crucial factor in determining which plant types will become established. Surface flow constructed wetlands offer the greatest potential to grow a wide variety of different types of macrophytes. In assessing the suitability of plant species for nutrient removal, consideration must be given not only to nutrient uptake for growth but also storage of nutrients as plant biomass. A survey of macrophytes in 15 surface flow constructed wetlands treating secondary effluent was conducted in Queensland; 63 native species and 14 introduced species were found. Emergent species have been able to tolerate deeper water than in their natural environment and permanent waterlogging. All species grew well in the higher nutrient enriched wastewater. Submerged, floating leaved-attached and free floating species had the highest tissue nutrient content, followed by aquatic creepers. All these species remove nutrients from the water column. Emergent species had lower nutrient content but a greater biomass and were therefore able to store more nutrients per unit area of wetland. In order to maximise the efficiency of constructed wetlands for nutrient removal, a range of species should be used. Native species should be selected in preference to introduced/exotic species.

    Blastocystis, an intestinal protist commonly found in humans and animals worldwide, has been implicated by some as a causative agent in irritable bowel syndrome in humans. In pigs, infection with Blastocystis is commonly reported, with most pigs shown to harbour subtypes (ST) 1 or 5, suggesting that these animals are potentially natural hosts for Blastocystis. Although ST5 is considered rare in humans, it has been reported to be a potential zoonosis from pigs in rural China. To test these hypotheses, we conducted molecular analysis of faecal samples from pigs and in-contact humans from commercial intensive piggeries in Southeast Queensland (SEQ), Australia, and a village in rural Cambodia. The prevalence of Blastocystis in SEQ and Cambodian pigs was 76.7% and 45.2%, respectively, with all positive pigs harbouring ST5. It appears likely that pigs are natural hosts of Blastocystis with a high prevalence of ST5 that is presumably the pig-adapted ST in these regions. Amongst the SEQ piggery staff, 83.3% were Blastocystis carriers in contrast to only 55.2% of Cambodian villagers. The predominant STs found in humans were STs 1, 2 (Cambodia only) and 3. Interestingly, ST5 which is usually rare in humans was present in the SEQ piggery staff but not in the Cambodian villagers. We conclude that in intensive piggeries, close contact between pigs and their handlers may increase the risks of zoonotic transmission of Blastocystis. Copyright © 2014 Elsevier B.V.

    In the spring of 2014, mass mortalities among wild green sea turtles occurred off the coast of south-east Queensland, Australia. The suspected causative agent was Caryospora cheloniae, an eimeriid coccidian implicated in previous epizootics. Necropsies were undertaken on a subset of 11 dead turtles, with subsequent histopathology and molecular analyses. All turtles returned positive PCR results for coccidial infection in various tissues; these included the brain, gastrointestinal tract, lung, kidney and thyroid. Granulomatous encephalitis was consistently observed, as well as enteritis and, less frequently, thyroiditis and nephritis. Sequencing and phylogenetic analyses indicated the presence of two distinct coccidian genotypes, presumably separate species-one associated with the brain, gastrointestinal tract and lung, and the second with the thyroid and kidney. Maximum likelihood and Bayesian inference analyses placed the first genotype closest to the lankesterellid genus Schellackia, rather than in the Eimeriidae, while the second was paraphyletic to the eimeriids. Presence of coccidial stages in extra-intestinal tissues of the primary host raises questions about the potential presence of intermediate or paratenic hosts within the life cycles, as well as their current placement relative to the genus Caryospora. This study represents the first genetic characterization of this emerging disease agent in green sea turtles, an endangered species, and has relevance for life-cycle elucidation and future development of diagnostics.

    Infection caused by Aeromonas spp. ranges from superficial wound infection to life-threatening septicemia. Carbapenem resistance due to metallo-beta-lactamase, CphA encoded by the cphA gene, is a significant problem. This study defines Aeromonas spp. causing clinical disease in Queensland, Australia. Phenotypic tests for carbapenemase detection were assessed. One hundred Aeromonas isolates from blood (22), wound (46), sterile sites (11), stool (18), eye (2), and sputum (1) were characterized by rpoB and gyrB sequencing. Meropenem susceptibility by VITEK2, disk diffusion, and E-test MIC were determined. Carbapenemase production was assessed by Carba NP test and cphA by PCR. Gene sequencing identified isolates as Aeromonas dhakensis (39), Aeromonas veronii (21), Aeromonas hydrophila (20), Aeromonas caviae (14), Aeromonas jandaei (4), Aeromonas bestiarum (1), and Aeromonas sanarellii (1). Disk diffusion and E-test failed to detect resistance in isolates with presence of cphA. Carba NP was performed with 97.4% sensitivity and 95.7% specificity. Carbapenem resistance gene cphA was detected in A. veronii (21; 100%), A. hydrophila (18; 90%), A. dhakensis (34; 87.2%), A. jandaei (3; 75%), and A. bestiarum (1; 100%) but not A. caviae. We found that A. dhakensis was the predominant species, a previously unrecognized pathogen in this region.

    The objective of this study is to address the question: are those who leave suicide notes representative of the larger population of those who commit suicide? The method involves an analysis of a full population of suicides by residents of Queensland, Australia for the full year of 2004, with the information drawn from Coronial files. Our overall results suggest that, and in support of previous research, the population who leaves suicide notes are remarkably similar to those who do not. Differences are identified in four areas: first, and in contrast to prior research, females are less likely to leave a suicide note; second, and in support of previous research, Aboriginal Australians are less likely to leave suicide notes; third, and in support of some previous research, those who use gas as a method of suicide are more likely to leave notes, while those who use a vehicle or a train are less likely to leave notes; finally, our findings lend support to research which finds that those with a diagnosed mental illness are less likely to leave notes. The discussion addresses some of the reasons these disparities may have occurred, and continues the debate over the degree to which suicide notes give insight into the larger suicide population.

    2013-09-01

    Full Text Available The banana leaf spotting disease yellow Sigatoka is established and actively controlled in Australia through intensive chemical treatments and diseased leaf removal. In the State of Queensland, the State government imposes standards for de-leafing to minimise the risk of the disease spreading in 6 banana pest quarantine areas. Of these, the Northern Banana Pest Quarantine Area is the most significant in terms of banana production. Previous regulations imposed obligations on owners of banana plants within this area to remove leaves from plants with visible spotting on more than 15 per cent of any leaf during the wet season. Recently, this leaf disease threshold has been lowered to 5 per cent. In this paper we examine the likely impact this more-costly regulation will have on the spread of the disease. We estimate that the average net benefit of reducing the diseased leaf threshold is only likely to be $1.4million per year over the next 30 years, expressed as the annualised present value of tightened regulation. This result varies substantially when the timeframe of the analysis is changed, with shorter time frames indicating poorer net returns from the change in protocols. Overall, the benefit of the regulation change is likely to be minor.

    Insecticide-treated lethal ovitraps are used for control of the dengue vector Aedes aegypti in north Queensland, Australia. In an effort to optimize their use, the influence of deployment height, premise shading, and protection from wind on trap efficacy was assessed in field experiments. Sticky ovitraps were used as a proxy for lethal ovitraps because they provide a direct measure of adult visitation rates. Sticky ovitraps deployed at ground level for 1 wk captured significantly more female Ae. aegypti (mean +/- SE, 1.7 +/- 0.4) than those set at 1.75-m elevation (1.0 +/- 0.3). Setting traps on the leeward side of houses significantly improved collections during a dry season experiment but not in the wet season. Traps set at lightly or heavily shaded premises performed equally well. To determine the optimum number of ovitraps to set per premise, five treatments making up different numbers of traps (1, 2, 4, 6, or 8) were trialled in a Latin square experimental design. Female Ae. aegypti collections increased as more traps were deployed, although mean collections by using 4 (2.6 +/- 0.6), 6 (2.4 +/- 0.5), or 8 traps (4.8 +/- 1.3) could not be separated statistically, suggesting that 4 traps was the optimum number for routine deployment.

    Full Text Available Illegal disposal of waste is a significant management issue for contemporary governments with waste posing an economic, social, and environmental risk. An improved understanding of the distribution of illegal waste disposal sites is critical to enhance the cost-effectiveness and efficiency of waste management efforts. Remotely sensed data has the potential to address this knowledge gap. However, the literature regarding the use of remote sensing to map illegal waste disposal sites is incomplete. This paper aims to analyze existing remote sensing methods and sensors used to monitor and map illegal waste disposal sites. The purpose of this paper is to support the evaluation of existing remote sensing methods for mapping illegal domestic waste sites in Queensland, Australia. Recent advances in technology and the acquisition of very high-resolution remote sensing imagery provide an important opportunity to (1 revisit established analysis techniques for identifying illegal waste disposal sites, (2 examine the applicability of different remote sensors for illegal waste disposal detection, and (3 identify opportunities for future research to increase the accuracy of any illegal waste disposal mapping products.

    An investigation into the health of green turtles was undertaken near Gladstone, Queensland, in response to a dramatic increase in stranding numbers in the first half of 2011. A total of 56 live turtles were subject to clinical examination and blood sampling for routine blood profiles, and 12 deceased turtles underwent a thorough necropsy examination. This population of green turtles was found to be in poor body condition and a range of infectious and non-infectious conditions were identified in the unhealthy turtles, including hepato-renal insufficiency (up to 81%, 27/33 based on clinical pathology), cachexia (92%, 11/12), parasitism (75%, 9/12), cardiopulmonary anomalies (42%, 5/12), gastroenteritis (25%, 3/12), masses (25%, 3/12) and mechanical impediments (17%, 2/12 based on necropsy). Overall, there was no evidence to indicate a unifying disease as a primary cause of the mass mortality. Recent adverse weather events, historic regional contamination and nearby industrial activities are discussed as potential causative factors.

  14. Development of a catchment/landscape erosion prediction model (MINErosion 4) for post-mining landscapes in Central Queensland, Australia.

    Open-cut coal mining in Central Queensland involves the breaking up of overburden that overlies the coal seams using explosives, followed by removal with draglines which results in the formation of extensive overburden spoil-piles with steep slopes at the angle of repose (approximately 75 % or 37o). These spoil-piles are found in long multiple rows, with heights of up to 60 or 70 m above the original landscapes. They are generally highly saline and dispersive and hence highly erosive. Legislation requires that these spoil-piles be rehabilitated into a stable self sustaining ecosystem with no off-site pollution. The first stage in the rehabilitation of these landscapes is the lowering of slopes to create a landscape that is stable against geotechnical failure and erosion. This is followed by revegetation generally with grasses as pioneer vegetation to further reduce erosion and a mixture of native shrubs and trees. Minimizing erosion and excessive on-site discharges of sediment into the working areas may result in the temporary cessation of mining operation with significant financial consequences, while off site discharges may breach the mining lease conditions. The average cost of rehabilitation is approximately 22,000 per ha. With more than 50,000 ha of such spoil-piles in Queensland at present, the total cost of rehabilitation facing the industry is very high. Most of this comprised the cost of reshaping the landscape, largely associated with the amount of material movement necessary to achieve the desired landscape. Since soil and spoil-piles vary greatly in their erodibilities, a hillslope erosion model MINErosion 3 (this conference) was developed to determine a cost effective combination of slope length, slope gradient and vegetation that will result in acceptable rates of erosion. This model was useful to determine the design parameters for the construction of a suitable post-mining landscape that meets the required erosion criteria. However, the mining

    In this study, 200 Escherichia coli isolates from 22 rainwater tank samples in Southeast Queensland, Australia, were tested for the presence of 20 virulence genes (VGs) associated with intestinal and extraintestinal pathotypes. In addition, E. coli isolates were also classified into phylogenetic groups based on the detection of the chuA, yjaA, and TSPE4.C2 genes. Of the 22 rainwater tanks, 8 (36%) and 5 (23%) were positive for the eaeA (belonging to enteropathogenic E. coli [EPEC] and Shiga-toxigenic E. coli [STEC]) and ST1 (belonging to enterotoxigenic E. coli [ETEC]) genes, respectively. VGs (cdtB, cvaC, ibeA, kpsMT allele III, PAI, papAH, and traT) belonging to extraintestinal pathogenic E. coli (ExPEC) were detected in 15 (68%) of the 22 rainwater tanks. Of the 22 samples, 17 (77%) and 11 (50%) contained E. coli belonging to phylogenetic groups A and B1, respectively. Similarly, 10 (45%) and 16 (72%) contained E. coli belonging to phylogenetic groups B2 and D, respectively. Of the 96 of the 200 strains from 22 tanks that were VG positive, 40 (42%) were carrying a single VG, 36 (37.5%) were carrying two VGs, 17 (18%) were carrying three VGs, and 3 (3%) had four or more VGs. This study reports the presence of multiple VGs in E. coli strains belonging to the STEC, EPEC, ETEC, and ExPEC pathotypes in rainwater tanks. The public health risks associated with potentially clinically significant E. coli in rainwater tanks should be assessed, as the water is used for drinking and other, nonpotable purposes. It is recommended that rainwater be disinfected using effective treatment procedures such as filtration, UV disinfection, or simply boiling prior to drinking.

    In this study, the microbiological quality of household tap water samples fed from rainwater tanks was assessed by monitoring the numbers of Escherichia coli bacteria and enterococci from 24 households in Southeast Queensland (SEQ), Australia. Quantitative PCR (qPCR) was also used for the quantitative detection of zoonotic pathogens in water samples from rainwater tanks and connected household taps. The numbers of zoonotic pathogens were also estimated in fecal samples from possums and various species of birds by using qPCR, as possums and birds are considered to be the potential sources of fecal contamination in roof-harvested rainwater (RHRW). Among the 24 households, 63% of rainwater tank and 58% of connected household tap water (CHTW) samples contained E. coli and exceeded Australian drinking water guidelines of tanks and 83% of CHTW samples also contained enterococci. In all, 21%, 4%, and 13% of rainwater tank samples contained Campylobacter spp., Salmonella spp., and Giardia lamblia, respectively. Similarly, 21% of rainwater tank and 13% of CHTW samples contained Campylobacter spp. and G. lamblia, respectively. The number of E. coli (P = 0.78), Enterococcus (P = 0.64), Campylobacter (P = 0.44), and G. lamblia (P = 0.50) cells in rainwater tanks did not differ significantly from the numbers observed in the CHTW samples. Among the 40 possum fecal samples tested, Campylobacter spp., Cryptosporidium parvum, and G. lamblia were detected in 60%, 13%, and 30% of samples, respectively. Among the 38 bird fecal samples tested, Campylobacter spp., Salmonella spp., C. parvum, and G. lamblia were detected in 24%, 11%, 5%, and 13% of the samples, respectively. Household tap water samples fed from rainwater tanks tested in the study appeared to be highly variable. Regular cleaning of roofs and gutters, along with pruning of overhanging tree branches, might also prove effective in reducing animal fecal contamination of rainwater tanks.

    The aim was to compare a private Commonwealth-initiated regional radiation oncology facility in Toowoomba with a Queensland Health facility (QHF) in Brisbane. The comparison concentrated on staffing, case mix and operational budgets, but was not able to look at changes in access to services. Data were collected from the two facilities from January 2008 to June 2008 inclusive. A number of factors were compared, including case mix, staffing levels, delay times for treatment, research, training and treatment costs. The case mix between the two areas was similar with curative treatments making up just over half the work load in both centres and two-thirds the work being made up of cancers of breast and prostate. Staffing levels were leaner in Toowoomba, especially in the areas of nursing, administration and trial coordinators. Research activity was slightly higher in Toowoomba. The average medicare cost per treatment course was similar in both centres ($5000 per course). Total costs of an average treatment including patient, State and Commonwealth costs, showed a 30% difference in costing favouring Toowoomba. This regional radiation oncology centre has provided state-of-the-art cancer care that is close to home for patients living in the Darling Downs region. Both public and private patients have been treated with modest costs to the patient and significant savings to QH. The case mix is similar to the QHF, and there has been significant activity in clinical research. A paperless working environment is one factor that has allowed staffing levels to be reduced. Ongoing support from Governments are required if private facilities are to participate in important ongoing staff training.

    Distracted driving is one of the most significant human factor issues in transport safety. Mobile phone interactions while driving may involve a multitude of cognitive and physical resources that result in inferior driving performance and reduced safety margins. The current study investigates characteristics of usage, risk factors, compensatory strategies in use and characteristics of high-frequency offenders of mobile phone use while driving. A series of questions were administered to drivers in Queensland (Australia) using an on-line questionnaire. A total of 484 drivers (34.9% males and 49.8% aged 17-25) participated anonymously. At least one of every two motorists surveyed reported engaging in distracted driving. Drivers were unable to acknowledge the increased crash risk associated with answering and locating a ringing phone in contrast to other tasks such as texting/browsing. Attitudes towards mobile phone usage were more favourable for talking than texting or browsing. Lowering the driving speed and increasing the distance from the vehicle in front were the most popular task-management strategies for talking and texting/browsing while driving. On the other hand, keeping the mobile phone low (e.g. in the driver's lap or on the passenger seat) was the favourite strategy used by drivers to avoid police fines for both talking and texting/browsing. Logistic regression models were fitted to understand differences in risk factors for engaging in mobile phone conversations and browsing/texting while driving. For both tasks, exposure to driving, driving experience, driving history (offences and crashes), and attitudes were significant predictors. Future mobile phone prevention efforts would benefit from development of safe attitudes and increasing risk literacy. Enforcement of mobile phone distraction should be re-engineered, as the use of task-management strategies to evade police enforcement seems to dilute its effect on the prevention of this behaviour.

    The goal of this article is to examine whether or not the results of the Queensland Community Engagement Trial (QCET)-a randomized controlled trial that tested the impact of procedural justice policing on citizen attitudes toward police-were affected by different types of nonresponse bias. We use two methods (Cochrane and Elffers methods) to explore nonresponse bias: First, we assess the impact of the low response rate by examining the effects of nonresponse group differences between the experimental and control conditions and pooled variance under different scenarios. Second, we assess the degree to which item response rates are influenced by the control and experimental conditions. Our analysis of the QCET data suggests that our substantive findings are not influenced by the low response rate in the trial. The results are robust even under extreme conditions, and statistical significance of the results would only be compromised in cases where the pooled variance was much larger for the nonresponse group and the difference between experimental and control conditions was greatly diminished. We also find that there were no biases in the item response rates across the experimental and control conditions. RCTs that involve field survey responses-like QCET-are potentially compromised by low response rates and how item response rates might be influenced by the control or experimental conditions. Our results show that the QCET results were not sensitive to the overall low response rate across the experimental and control conditions and the item response rates were not significantly different across the experimental and control groups. Overall, our analysis suggests that the results of QCET are robust and any biases in the survey responses do not significantly influence the main experimental findings.

    Simultaneous personal measurements of the occupational ultraviolet exposure weighted to the International Commission on Non-Ionising Radiation Protection hazard sensitivity spectrum (UVICNIRP) were made over a five week period (44 person-days) in the second half of the summer school term of 2012 in Queensland, Australia for individual high school teachers located at latitudes of 27.5°S and 23.5°S. These teachers were employed for the duration of the study in a predominately indoor classroom teaching role, excluding mandatory periods of lunch time yard duty and school sport supervisions. Data is presented from personal measurements made to the shirt collar using polyphenylene oxide (PPO) film UV dosimeters. UVICNIRP exposure data is presented for each week of the study period for the shirt collar measurement site and are further expressed relative to the measured ambient horizontal plane exposure. Personal exposures were correlated with time outdoors, showing a higher exposure trend on days when teachers were required to supervise outdoor areas for more than 2h per week (mean daily exposure: 168Jm(-2)UVICNIRP±5Jm(-2) (1σ)) compared to the study average (mean daily exposure: 115Jm(-2)UVICNIRP±91Jm(-2) (1σ)). Time spent in an open playground environment was found to be the most critical factor influencing the occupational UVICNIRP exposure. A linear model was developed showing a correlation (R(2)=0.77) between the time teachers spent on yard duty and UVICNIRP exposure, expressed relative to ambient. The research findings indicate a greater reduction in personal exposure can be achieved by timetabling for yard duty periods in playground areas which offer more shade from trees and surrounding buildings. All mean daily personal exposures measured at the shirt collar site were higher than the ICNIRP occupational daily exposure limit of 30Jm(-2) for outdoor workers.

    Veterinary infection control for the management of Hendra virus (HeV), an emerging zoonosis in Australia, remained suboptimal until 2010 despite 71.4% (5/7) of humans infected with HeV being veterinary personnel or assisting a veterinarian, three of whom died before 2009. The aim of this study was to identify the perceived barriers to veterinary infection control and HeV management in private veterinary practice in Queensland, where the majority of HeV outbreaks have occurred in Australia. Most participants agreed that a number of key factors had contributed to the slow uptake of adequate infection control measures for the management of HeV amongst private veterinarians: a work culture characterised by suboptimal infection control standards and misconceptions about zoonotic risks; a lack of leadership and support from government authorities; the difficulties of managing biosecurity and public health issues from a private workforce perspective; and the slow pattern of emergence of HeV. By 2010, some infection control and HeV management changes had been implemented. Participants interviewed agreed that further improvements remained necessary; but also cautioned that this was a complex process which would require time. Private veterinarians and government authorities prior to 2009 were unprepared to handle new slowly emerging zoonoses, which may explain their mismanagement of HeV. Slowly emerging zoonoses may be of low public health significance but of high significance for specialised groups such as veterinarians. Private veterinarians, who are expected to fulfil an active biosecurity and public health role in the frontline management of such emerging zoonoses, need government agencies to better recognise their contribution, to consult with the veterinary profession when devising guidelines for the management of zoonoses and to provide them with greater leadership and support. We propose that specific infection control guidelines for the management of slowly emerging

    In North America and Europe, the binary toxin positive Clostridium difficile strains of the ribotypes 027 and 078 have been associated with death, toxic megacolon and other adverse outcomes. Following an increase in C. difficile infections (CDIs) in Queensland, a prevalence study involving 175 hospitals was undertaken in early 2012, identifying 168 cases of CDI over a 2 month period. Patient demographics and clinical characteristics were recorded, and C. difficile isolates were ribotyped and tested for the presence of binary toxin genes. Most patients (106/168, 63.1%) were aged over 60 years. Overall, 98 (58.3%) developed symptoms after hospitalisation; 89 cases (53.0%) developed symptoms more than 48 hours after admission. Furthermore, 27 of the 62 (67.7%) patients who developed symptoms in the community ad been hospitalised within the last 3 months. Thirteen of the 168 (7.7%) cases identified had severe disease, resulting in admission to the Intensive Care Unit or death within 30 days of the onset of symptoms. The 3 most common ribotypes isolated were UK 002 (22.9%), UK 014 (13.3%) and the binary toxin-positive ribotype UK 244 (8.4%). The only other binary toxin positive ribotype isolated was UK 078 (n = 1). Of concern was the detection of the binary toxin positive ribotype UK 244, which has recently been described in other parts of Australia and New Zealand. No isolates were of the international epidemic clone of ribotype UK 027, although ribotype UK 244 is genetically related to this clone. Further studies are required to track the epidemiology of ribotype UK 244 in Australia and New Zealand.

    Creating a stable and sustainable health workforce in regional, rural and remote Australia has long been a challenge to health workforce planners, policy makers and researchers alike. Traditional health workforce planning is often reactive and assumes continuation of current patterns of healthcare utilisation. This demonstration project in Far North Queensland exemplifies how participatory regional health workforce planning processes can accurately model current and projected local workforce requirements. The recent establishment of Primary Health Networks (PHNs) with the intent to commission health services tailored to individual healthcare needs underlines the relevance of such an approach. This study used action research methodology informed by World Health Organization (WHO) systems thinking. Four cyclical stages of health workforce planning were followed: needs assessment; health service model redesign; skills-set assessment and workforce redesign; and development of a workforce and training plan. This study demonstrated that needs-based loco-regional health workforce planning can be achieved successfully through participatory processes with stakeholders. Stronger health systems and workforce training solutions were delivered by facilitating linkages and planning processes based on community need involving healthcare professionals across all disciplines and sectors. By focusing upon extending competencies and skills sets, local health professionals form a stable and sustainable local workforce. Concrete examples of initiatives generated from this process include developing a chronic disease inter-professional teaching clinic in a rural town and renal dialysis being delivered locally to an Aboriginal community. The growing trend of policy makers decentralising health funding, planning and accountability and rising health system costs increase the future utility of this approach. This type of planning can also assist the new PHNs to commission health services

    As urban and suburban areas expand into previously unoccupied sites, the problem of accurately determining the locations of abandoned mine workings and the possible effects of fault reactivation on surface subsidence becomes more important. Here, we present the results of DC electrical resistivity imaging (ERI) surveys above an abandoned coal mine in the Jurassic Walloon Coal Measures of the Clarence-Moreton Basin, Queensland. Objectives were to: (1) locate the surface entrance to a coal mine access shaft, (2) determine the extent of the mine workings, (3) determine if the workings are open, partly- or fully-collapsed, (4) locate the possible existence of a high angle fault delineating the western extent of the workings. Coal seams were mined underground by the bord-and-pillar technique at the site until the first half of the 20th century to within ~20 m of the ground surface. This has led to ground settlement post-abandonment, with an additional hazard of this stress-redistribution being the possible reactivation of steeply-dipping faults known to pervade the coal measures. After an initial site reconnaissance, desktop study and modelling, it was determined that existing mine plans, maps and records were poorly kept and inaccurate, making a satisfactory geotechnical risk assessment prior to land development and construction difficult. The 2D ERI transects, coupled with boreholes, identified lateral zones of moderate-high resistivity that are interpreted to be partly-collapsed workings. The second key feature identified was a reverse fault that delineated the western edge of the mine workings. The key outcome is that for abandoned mine risk assessment to be optimised, careful integration of geophysical data and direct testing needs to be made.

    X-ray Operator (XO) supervision in Queensland is performed by radiographers in a site removed from the XO site. This has historically been performed by telephone when the XO requires immediate help, as well as post-examination through radiographer review and the provision of written feedback on images produced. This project aimed to improve image quality through the provision of real-time support of XOs by the introduction of video conference (VC) supervision. A 6-month pilot project compared image quality with and without VC supervision. VC equipment was installed in the X-ray room at two rural sites, as well as at the radiographer site, to enable visual and oral supervision. The VC unit enabled visualisation of the X-ray examination technique as it was being undertaken, as well as the images produced prior to transmission to the Picture Archiving and Communication System (PACS). Statistically significant improvement in image quality criteria measures were seen for patient positioning (P = 0.008), image quality (P radiographer for assistance, although, assistance was actually provided in 88.3% of examinations. This project has demonstrated that significant improvement in image quality is achievable with VC supervision. A larger study with a control arm that did not receive direct supervision should be used to validate the findings of this study. © 2017 The Authors.

However, maps of forests are different stages of regeneration are needed to facilitate restoration planning, including prevention of further re-clearing. Focusing on the Tara Downs subregion of the BBB and on forests with brigalow (Acacia harpophylla as a component, this research establishes a method for differentiating and mapping early, intermediate and remnant growth stages from Japan Aerospace Exploration Agency (JAXA Advanced Land Observing Satellite (ALOS Phased-Array L-band Synthetic Aperture Radar (PALSAR Fine Beam Dual (FBD L-band HH- and HV-polarisation backscatter and Landsat-derived Foliage Projective Cover (FPC. Using inventory data collected from 74 plots, located in the Tara Downs subregion, forests were assigned to one of three regrowth stages based on their height and cover relative to that of undisturbed stands. The image data were then segmented into objects with each assigned to a growth stage by comparing the distributions of L-band HV and HH polarisation backscatter and FPC to that of reference distributions using a z-test. Comparison with independent assessments of growth stage, based on time-series analysis of aerial photography and SPOT images, established an overall accuracy of > 70%, with this increasing to 90% when intermediate regrowth was excluded and only early-stage regrowth and remnant classes were considered. The proposed method can be adapted to respond to amendments to user-definitions of growth stage and, as regional mosaics of ALOS PALSAR and Landsat FPC are available for Queensland, has application across the state.

    Induced abortions after 20 weeks' gestation comprise around one per cent of all terminations in Australia and mostly occur following the diagnosis of a fetal anomaly. However, these abortions are overly represented in legal cases against doctors and challenging to organise in those states where abortion remains in the criminal code and health department directives impose regulations. This study explores barriers to abortion access after 20 weeks' gestation in the states of Queensland and New South Wales. We approached and sought consent from 22 doctors involved in abortion provision (15 in Queensland and seven in NSW), who responded in depth to a set of clinical scenarios. This study presents participants' responses to three clinical scenarios of women presenting with a fetal chromosomal abnormality after 20 weeks' gestation. Of the 22 medical practitioners in this study, 18 reported that access to late-term abortion in their state was restricted. The two key factors perceived to affect the decision to terminate a pregnancy in this context were the legal status of abortion and Department of Health policies mandating that applications for abortion be presented to clinical ethics committees. Practitioners reported that committees were slow to convene and inconsistent in their decisions. Ethics committee involvement for late-term abortions is required by state health policy in NSW and Queensland, where abortion is still a criminal offence. This process is seen by abortion providers to hinder timely access to services and excludes women from the decision-making process. © 2015 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

    Introduction Radiation dose to patients undergoing invasive coronary angiography (ICA) is relatively high. Guidelines suggest that a local benchmark or diagnostic reference level (DRL) be established for these procedures. This study sought to create a DRL for ICA procedures in Queensland public hospitals. Methods Data were collected for all Cardiac Catheter Laboratories in Queensland public hospitals. Data were collected for diagnostic coronary angiography (CA) and single-vessel percutaneous intervention (PCI) procedures. Dose area product (PKA), skin surface entrance dose (KAR), fluoroscopy time (FT), and patient height and weight were collected for 3 months. The DRL was set from the 75th percentile of the PKA. Results 2590 patients were included in the CA group where the median FT was 3.5 min (inter-quartile range = 2.3–6.1). Median KAR = 581 mGy (374–876). Median PKA = 3908 uGym2 (2489–5865) DRL = 5865 uGym2. 947 patients were included in the PCI group where median FT was 11.2 min (7.7–17.4). Median KAR = 1501 mGy (928–2224). Median PKA = 8736 uGym2 (5449–12,900) DRL = 12,900 uGym2. Conclusion This study established a benchmark for radiation dose for diagnostic and interventional coronary angiography in Queensland public facilities. PMID:26229649

    Native grasslands cover over 80% of significant ecosystems in Australia, stretching across arid, semi-arid, tropical, sub-tropical and savannah landscapes. Scales of pastoral operations in Australia range from hundreds of hectares to thousands of square kilometres and are predominately found in regions with highly variable rainfall. Land use is governed by the need to cope with droughts, floods and fires. Resilience to climatic extremes can be attained through effective soil management. Connecting landscape function on the fine scale to broad land management objectives is a critical step in evaluation and requires an understanding of the relevant spectral properties in remotely sensed images. The aim of this study was to assess key landscape function indices across spatial scales in order to examine their correlation with hyperspectral reflectance measurements. The results from this study could be applied as a model for land management centred on remote sensing. The study site is located at Stonehenge (southern Queensland) on a moderately deep texture contrast soil with hard setting gravelly topsoil. Mean annual rainfall of 667 mm supports open forest and native perennial pastures with a diverse biocrust dominated by N-fixing cyanobacteria. Land use history is continuous grazing however; it had been destocked for several years prior to our study. There was some evidence of cattle, kangaroos and feral herbivores (rabbits, deer and goats) although impacts appeared to be minimal. We established four land cover types: native pasture - NP1 (~100% FPC - foliage projective cover), native pasture - NP2 (~50% FPC, 50% biocrust), natural bare soil - BC (>80% biocrust), bare and eroded soil - BE (conditions and, with FPC removed in order to record the presence of biocrusts. For each micro-transect, soil samples were taken at 0-1 cm and 1-5 cm depths for isotopic C and N, C:N ratio, and plant-available N analysis.

    Full Text Available Abstract Background Australian General Practitioners (GPs are in the forefront of primary health care and in an excellent position to communicate with their patients and educate them about Complementary Medicines (CMs use. However previous studies have demonstrated that GPs lack the knowledge required about CMs to effectively communicate with patients about their CMs use and they perceive a need for information resources on CMs to use in their clinical practice. This study aimed to develop, implement, and evaluate a CMs information resource in Queensland (Qld general practice. Methods The results of the needs assessment survey of Qld general practitioners (GPs informed the development of a CMs information resource which was then put through an implementation and evaluation cycle in Qld general practice. The CMs information resource was a set of evidence-based herbal medicine fact sheets. This resource was utilised by 100 Qld GPs in their clinical practice for four weeks and was then evaluated. The evaluation assessed GPs' (1 utilisation of the resource (2 perceived quality, usefulness and satisfaction with the resource and (3 perceived impact of the resource on their knowledge, attitudes, and practice of CMs. Results Ninety two out of the 100 GPs completed the four week evaluation of the fact sheets and returned the post-intervention survey. The herbal medicine fact sheets produced by this study were well accepted and utilised by Qld GPs. The majority of GPs perceived that the fact sheets were a useful resource for their clinical practice. The fact sheets improved GPs' attitudes towards CMs, increased their knowledge of those herbal medicines and improved their communication with their patients about those specific herbs. Eighty-six percent of GPs agreed that if they had adequate resources on CMs, like the herbal medicine fact sheets, then they would communicate more to their patients about their use of CMs. Conclusion Further educational

The aim of the present study was to describe the consistency between two services for the types and frequency of tasks provided and the agreement between teams in the decision to delegate or skill share clinical tasks, thereby determining the potential applicability to other services.Methods Datasets provided by two similar services were collated. Descriptive statistical analyses were used to assess the extent of agreement.Results In all, 214 tasks were identified as being undertaken by the services (92% agreement). Across the services, 70 tasks were identified as high frequency (equal to or more frequently than weekly) and 29 as not high frequency (46% agreement). Of the 68 tasks that were risk assessed, agreement was 66% for delegation and 60% for skill sharing, with high-frequency and intervention tasks more likely to be delegated.Conclusions Strong consistency was apparent for the clinical tasks undertaken by the two cancer care AH teams, with moderate agreement for the frequency of tasks performed. The proportion of tasks considered appropriate for skill sharing and/or delegation was similar, although variation at the task level was apparent. Further research is warranted to examine the range of factors that affect the decision to skill share or delegate.What is known about the topic? There is limited research evidence regarding the use of skill sharing and delegation service models for AH in cancer care services. In particular, the extent to which decisions about task safety and appropriateness for delegation or skill sharing can be generalised across services has not been investigated.What does this paper add? This study investigated the level of clinical task consistency between two similar AH cancer care teams in regional centres. It also examined the level of agreement with regard to delegation

    There is overwhelming scientific evidence that human activities have changed and will continue to change the climate of the Earth. Eco-environmental health, which refers to the interdependencies between ecological systems and population health and well-being, is likely to be significantly influenced by climate change. The aim of this study was to examine perceptions from government stakeholders and other relevant specialists about the threat of climate change, their capacity to deal with it, and how to develop and implement a framework for assessing vulnerability of eco-environmental health to climate change. Two focus groups were conducted in Brisbane, Australia with representatives from relevant government agencies, non-governmental organisations, and the industry sector (n = 15) involved in the discussions. The participants were specialists on climate change and public health from governmental agencies, industry, and non-governmental organisations in South-East Queensland. The specialists perceived climate change to be a threat to eco-environmental health and had substantial knowledge about possible implications and impacts. A range of different methods for assessing vulnerability were suggested by the participants and the complexity of assessment when dealing with multiple hazards was acknowledged. Identified factors influencing vulnerability were perceived to be of a social, physical and/or economic nature. They included population growth, the ageing population with associated declines in general health and changes in the vulnerability of particular geographical areas due to for example, increased coastal development, and financial stress. Education, inter-sectoral collaboration, emergency management (e.g. development of early warning systems), and social networks were all emphasised as a basis for adapting to climate change. To develop a framework, different approaches were discussed for assessing eco-environmental health vulnerability, including literature

    Terrestrial laser scanning (TLS) technology is a powerful tool for quantifying gully morphology and monitoring change over time. This is due to the high sampling density, sub-centimetre positional accuracies (x, y, z), flexibility of survey configurations and ability to link multiple TLS scans together. However, to ensure correct interpretation of results, research is needed to test the repeatability of TLS derived products to quantify the accuracy and separate 'false' from 'true' geomorphic change. In this study, we use the RIEGL VZ400 scanner to test the repeatability of TLS datasets for mapping gully morphology. We then quantify change following a rainfall event of approximately 100 mm. Our study site, located in south-east Queensland, Australia was chosen to be challenging from a repeatability perspective with high topographic variability. The TLS data capture involved three sets of linked scans: one survey pre-rainfall, to be compared to two surveys post-rainfall acquired on consecutive days. Change is considered negligible in the two post-rainfall scans to test survey repeatability. To verify TLS accuracy, an independent dataset of gully extent and spot heights were acquired using traditional total station techniques. Results confirm that the TLS datasets can be registered multi-temporally at sub-centimetre levels of accuracy in three dimensions. Total station and TLS elevation samples showed strong agreement with a mean error and standard deviation (SD) of residuals equal to 0.052 and 0.047 m, respectively (n = 889). Significantly, our repeatability tests found that return type and pulse deviation influence the accuracy and repeatability of DEMs in gully environments. Analysis of consecutive day datasets showed that DEMs derived from first return data recorded 40% higher SD of residual error than DEMs using multiple return data. A significant empirical relationship between pulse deviation and the variance of residuals for repeat DEMs is also shown (r2 = 0

    We explored the impact of canopy position on leaf respiration (R) and associated traits in tree and shrub species growing in a lowland tropical rainforest in Far North Queensland, Australia. The range of traits quantified included: leaf R in darkness (RD) and in the light (RL; estimated using the Kok method); the temperature (T)-sensitivity of RD; light-saturated photosynthesis (Asat); leaf dry mass per unit area (LMA); and concentrations of leaf nitrogen (N), phosphorus (P), soluble sugars and starch. We found that LMA, and area-based N, P, sugars and starch concentrations were all higher in sun-exposed/upper canopy leaves, compared with their shaded/lower canopy and deep-shade/understory counterparts; similarly, area-based rates of RD, RL and Asat (at 28 °C) were all higher in the upper canopy leaves, indicating higher metabolic capacity in the upper canopy. The extent to which light inhibited R did not differ significantly between upper and lower canopy leaves, with the overall average inhibition being 32% across both canopy levels. Log-log RD-Asat relationships differed between upper and lower canopy leaves, with upper canopy leaves exhibiting higher rates of RD for a given Asat (both on an area and mass basis), as well as higher mass-based rates of RD for a given [N] and [P]. Over the 25-45 °C range, the T-sensitivity of RD was similar in upper and lower canopy leaves, with both canopy positions exhibiting Q10 values near 2.0 (i.e., doubling for every 10 °C rise in T) and Tmax values near 60 °C (i.e., T where RD reached maximal values). Thus, while rates of RD at 28 °C decreased with increasing depth in the canopy, the T-dependence of RD remained constant; these findings have important implications for vegetation-climate models that seek to predict carbon fluxes between tropical lowland rainforests and the atmosphere.

    Full Text Available Phytoliths are micrometric particles of amorphous silica that form inside or between the cells of higher plant tissues throughout the life of a plant. With plant decay, phytoliths are either incorporated into soils or exported to sediments via regional watersheds. Phytolith morphological assemblages are increasingly used as proxy of grassland diversity and tree cover density in inter-tropical areas. Here, we investigate whether, along altitudinal gradients in northeast Queensland (Australia, changes in the δ18O signature of soil top phytolith assemblages reflect changes in mean annual temperature (MAT and in the oxygen isotopic composition of precipitation (δ18Oprecipitation, as predicted by equilibrium temperature coefficients previously published for silica. Oxygen isotopic analyses were performed on 16 phytolith samples, after controlled isotopic exchange (CIE, using the IR Laser-Heating Fluorination Technique. Long-term mean annual precipitation (MAP and MAT values at the sampled sites were calculated by the ANUCLIM software. δ18Oprecipitation estimates were calculated using the Bowen and Wilkinson (2002 model, slightly modified. An empirical temperature-dependant relationship was obtained: δ18Owood phytolith-precipitation (‰ vs. VSMOW = −0.4 (±0.2 t (°C + 46 (±3 (R2 = 0.4, p < 0.05; n = 12. Despite the various unknowns introduced when estimating δ18Oprecipitation values and the large uncertainties on δ18Owood phytolith values, the temperature coefficient (−0.4 ± 0.2‰ °C−1 is in the range of values previously obtained for natural quartz, fresh and sedimentary diatoms and harvested grass phytoliths (from −0.2 to −0.5‰ °C−1. The consistency supports the reliability of δ18Owood phytolith signatures for recording

    Full Text Available When a parasite finds a new wildlife host, impacts can be significant. In the late 1980s populations of Spectacled Flying-foxes (SFF (Pteropus conspicillatus, a species confined, in Australia, to north Queensland became infected by paralysis tick (Ixodes holocyclus, resulting in mortality. This Pteropus-tick relationship was new to Australia. Curiously, the relationship was confined to several camps on the Atherton Tableland, north Queensland. It was hypothesised that an introduced plant, wild tobacco (Solanum mauritianum, had facilitated this new host-tick interaction. This study quantifies the impact of tick paralysis on SFF and investigates the relationship with climate. Retrospective analysis was carried out on records from the Tolga Bat Hospital for 1998-2010. Juvenile mortality rates were correlated to climate data using vector auto-regression. Mortality rates due to tick paralysis ranged between 11.6 per 10,000 bats in 2003 and 102.5 in 2009; more female than male adult bats were affected. Juvenile mortality rates were negatively correlated with the total rainfall in January to March and July to September of the same year while a positive correlation of these quarterly total rainfalls existed with the total population. All tick affected camps of SFF were located in the 80% core range of S. mauritianum. This initial analysis justifies further exploration of how an exotic plant might alter the relationship between a formerly ground-dwelling parasite and an arboreal host.

    Full Text Available Abstract Background Multicentre drug use evaluations are described in the literature infrequently and usually publish only the results. The purpose of this paper is to describe the experience of Queensland hospitals participating in the Community-Acquired Pneumonia Towards Improving Outcomes Nationally (CAPTION project, specifically evaluating the implementation of this project, detailing benefits and drawbacks of involvement in a national drug use evaluation program. Methods Emergency departments from nine hospitals in Queensland, Australia, participated in CAPTION, a national quality improvement project, conducted in 37 Australian hospitals. CAPTION was aimed at optimising prescribing in the management of Community-Acquired Pneumonia according to the recommendations of the Australian Therapeutic Guidelines: Antibiotic 12th edition. The project involved data collection, and evaluation, feedback of results and a suite of targeted educational interventions including audit and feedback, group presentations and academic detailing. A baseline audit and two drug use evaluation cycles were conducted during the 2-year project. The implementation of the project was evaluated using feedback forms after each phase of the project (audit or intervention. At completion a group meeting with the hospital coordinators identified positive and negative elements of the project. Results Evaluation by hospitals of their participation in CAPTION demonstrated both benefits and drawbacks. The benefits were grouped into the impact on the hospital dynamic such as; improved interdisciplinary working relationships (e.g. between pharmacist and doctor, recognition of the educational/academic role of the pharmacist, creation of ED Pharmacist positions and enhanced involvement with the National Prescribing Service, and personal benefits. Personal benefits included academic detailing training for participants, improved communication skills and opportunities to present at

    Indigenous women in remote North Queensland have a high prevalence of unhealthy lifestyle behaviors and associated health conditions such as sexual transmitted infections (STI). The association of severe pelvic inflammatory disease (PID) with these factors has not been studied. The purpose of this study is to associate the factors with severe PID, as indicated by hospitalization in a high risk population in North Queensland Indigenous communities. A cross-sectional association of 1445 Indigenous women using linked hospital separation and survey data during 1998-2005. The mean age of participating women was 37.4 years, 60% were of Aboriginal and 40% were Torres Strait Island (TSI) people. More than half of them (52.5%) were smokers, 9.3% had chlamydia and 2.6% had gonorrhoea with the overall prevalence of STI among those less than 25 years of age being 23.9%. Among the 47 participants diagnosed with PID in the study period, 42.5% were under 25 years and 95.7% (45 cases) were under 55 years (OR 2.5, 95% CI 1.2-4.1 among women younger than 25 compared to those 25 years and over). PID was strongly associated with smoking (OR 3.1, 95% CI 1.4-9.2) independent of age, ethnicity, STI and folate status. Low red cell folate increased PID hospitalization by 4 times (95% CI 1.5-13.2 of lowest quartile compared to the highest quartile) regardless of age. Having a STI significantly increased the likelihood of severe PID by 2.2 times (95% CI: 1.03-4.5) in Indigenous women younger than 45 years, independent of smoking and folate level. The risk of PID hospitalization was higher for gonorrheal infections (OR 3.2, 955 CI 1.1-9.6) compared to chlamydial infections (OR 1.5 95% CI 0.7-3.5). Young Indigenous women in North Queensland communities are at very high risk for STI and PID. Smoking, low folate, and STI are clustered, and are associated with PID hospitalizations. Much of this can be prevented with improved nutrition and access to preventive services, especially tobacco

    Airborne laser scanning (ALS) and terrestrial laser scanning (TLS) technologies capture spatially detailed estimates of surface topography and when collected multi-temporally can be used to assess geomorphic change. The sensitivity and repeatability of ALS measurements to characterise geomorphic change in topographically complex environments such as gullies; however, remains an area lacking quantitative research. In this study, we captured coincident ALS and TLS datasets to assess their ability and synergies to detect geomorphic change for a gully located in Aratula, southeast Queensland, Australia. We initially used the higher spatial density and ranging accuracy of TLS to provide an assessment of the Digital Elevation Models (DEM) derived from ALS within a gully environment. Results indicated mean residual errors of 0.13 and 0.09 m along with standard deviation (SD) of residual errors of 0.20 and 0.16 m using pixel sizes of 0.5 and 1.0 m, respectively. The positive mean residual errors confirm that TLS data consistently detected deeper sections of the gully than ALS. We also compared the repeatability of ALS and TLS for characterising gully morphology. This indicated that the sensitivity to detect change using ALS is substantially lower than TLS, as expected, and that the ALS survey characteristics influence the ability to detect change. Notably, we found that using one ALS transect (mean density of 5 points / m2) as opposed to three transects increased the SD of residual error by approximately 30%. The supplied classification of ALS ground points was also demonstrated to misclassify gully features as non-ground, with minimum elevation filtering found to provide a more accurate DEM of the gully. The number and placement of terrestrial laser scans were also found to influence the derived DEMs. Furthermore, we applied change detection using two ALS data captures over a four year period and four TLS field surveys over an eight month period. This demonstrated that

    This paper examines the environmental risk and impact of trace metals affecting river water and sediment in and around Mount Isa, Queensland, Australia. Bacterial indicator densities are also analysed throughout the catchment to assess the impacts and the potential hazards arising from agricultural activities, sewage treatment plant releases and urban runoff. The area is drained by the ephemeral Leichhardt River, which bisects Mount Isa City and the major Pb, Zn, Cu and Ag Mount Isa Mine. Runoff is captured downstream in Lake Moondarra, with the water being used following natural filtration via a lagoon-reed bed system for potable purposes by the residents of Mount Isa City. During the dry season, the channel is characterised by numerous pools that act as storage zones for sediment and water-soluble metals as well as urban and agriculturally derived nutrients and pathogens. Our results show that sediment and water quality within the Leichhardt River adjacent to and downstream of the mine frequently exceed Australian government sediment guidelines with average values of Cu, Pb and Zn found adjacent to the footprint of the mine being 1550, 510 and 470 mg kg(-1), respectively. Dry season analysis of water-soluble Cu, Pb and Zn concentrations within pools showed that Australian government low trigger guidelines are exceeded in 100, 46 and 100% cases, respectively. The densities of bacterial indicators in remnant pools throughout the Leichhardt River also exceeded acceptable guidelines. Maximum dry season faecal coliform densities of 2000 colony forming units (CFU) per 100 mL and Enterococcus counts of 900 organisms per 100 mL were recorded in dry season remnant pools compared to wet season maximum faecal coliform and Enterococcus densities of 119 000 CFU per 100 mL and 95 000 organisms per 100 mL, respectively. The impacts on biota were also examined by assessing the metal content of the tissue of seven fish from Lake Moondarra for their Cd, Cu, Hg, Pb and Zn

    A predictive model for streamflow has practical implications for understanding the drought hydrology, environmental monitoring and agriculture, ecosystems and resource management. In this study, the state-or-art extreme learning machine (ELM) model was utilized to simulate the mean streamflow water level (Q WL) for three hydrological sites in eastern Queensland (Gowrie Creek, Albert, and Mary River). The performance of the ELM model was benchmarked with the artificial neural network (ANN) model. The ELM model was a fast computational method using single-layer feedforward neural networks and randomly determined hidden neurons that learns the historical patterns embedded in the input variables. A set of nine predictors with the month (to consider the seasonality of Q WL); rainfall; Southern Oscillation Index; Pacific Decadal Oscillation Index; ENSO Modoki Index; Indian Ocean Dipole Index; and Nino 3.0, Nino 3.4, and Nino 4.0 sea surface temperatures (SSTs) were utilized. A selection of variables was performed using cross correlation with Q WL, yielding the best inputs defined by (month; P; Nino 3.0 SST; Nino 4.0 SST; Southern Oscillation Index (SOI); ENSO Modoki Index (EMI)) for Gowrie Creek, (month; P; SOI; Pacific Decadal Oscillation (PDO); Indian Ocean Dipole (IOD); EMI) for Albert River, and by (month; P; Nino 3.4 SST; Nino 4.0 SST; SOI; EMI) for Mary River site. A three-layer neuronal structure trialed with activation equations defined by sigmoid, logarithmic, tangent sigmoid, sine, hardlim, triangular, and radial basis was utilized, resulting in optimum ELM model with hard-limit function and architecture 6-106-1 (Gowrie Creek), 6-74-1 (Albert River), and 6-146-1 (Mary River). The alternative ELM and ANN models with two inputs (month and rainfall) and the ELM model with all nine inputs were also developed. The performance was evaluated using the mean absolute error (MAE), coefficient of determination (r (2)), Willmott's Index (d), peak deviation (P dv), and Nash

    Full Text Available Variations in the oxygen isotopic composition of precipitation (δ18Oprecipitation in inter-tropical areas mainly record variations in water sources, amounts of precipitation, and atmospheric temperature and provide information regarding local climate and regional atmospheric circulation changes. On continents, fossil biogenic minerals and speleothems formed in isotopic equilibrium with water can produce continuous δ18O records and are becoming increasingly valuable for reconstructing past climate changes. Here, we explore the efficiency and limitations of using the oxygen isotopic composition of wood phytoliths (δ18Owood phytolith from tropical rainforest soils as a suitable proxy for atmospheric temperature and δ18Oprecipitation values, under conditions that are assumed to be non-evaporative. Soil phytolith assemblages, that should contain 100s of years of phytolith production, were collected along four altitude, temperature, and precipitation gradients in the Queensland rainforests (Australia. Oxygen isotopic analyses were performed on 1.6 mg phytolith samples, after controlled isotopic exchange (CIE, using the IR Laser-Heating Fluorination Technique. Long-term mean annual precipitation (MAP and mean annual temperature (MAT values at the sampled sites were obtained using a regional GIS database. The δ18Oprecipitation values were estimated. The δ18Owood phytolith values from the leeward slopes were scattered but recorded the modern combination of weighted mean annual δ18Oprecipitation values and MAT. The empirical relationship was &Delta18Owood phytolith-precipitation (‰ vs. VSMOW = −0.4 (±0.2 t (°C + 46 (±3 (R2 = 0.4, p<0.05; n=12. δ18Oprecipitation estimates were close to estimates for δ18

    This paper examines the storage and transfer of trace metal contaminants in water and sediment within the upper Leichhardt River Catchment (1,113 km2), Mount Isa, north-west Queensland. The Leichhardt River runs adjacent to Mount Isa City and the Cu and Pb-Zn-Ag Mount Isa Mine and smelter (MIM) and feeds Lake Moondarra, Mount Isa's potable water supply. The river flows only during the monsoonal wet season (December- March) and for the remainder of the year is characterised by a series of disconnected temporary and permanent pools ranging in length from 10 m to 1 km. These pools are significant because they act as storage zones for water-soluble and sediment-associated metals and serve as refugia for native and domestic fauna during protracted intervals between wet season flows. To recognise seasonal fluxes and cycling patterns of trace metal contaminants in the Leichhardt River system this study investigates the physico-chemical water quality of the wet season flows and the subsequent seasonal variations in the dry season pool water. In January 2007 two floods were studied using sixteen rising stage water quality samplers along the Leichhardt River. The samplers were placed above and below MIM, and within selected tributaries draining MIM to ascertain the specific impacts from mining activities on water quality. Grab samples were also collected during the floods and on the falling stages of flow within the river system. Following this, dry season water quality sampling commenced on eleven remnant pools over a period of 8 months. Overall 60 wet season and 34 dry season water samples were collected and analysed for physico-chemical (pH, EC, DO, TDS, SS) variables in the field and total and water soluble cations, trace elements of concern (Cd, Cu, Pb, Zn) and anions via ICP-MS and ion chromatography, respectively. In addition, mineralogical and geochemical analysis was undertaken on 34 bottom sediment samples collected from the pools. Analysis of the temporal metal

    The average total population of bacteria remained constant in the alimentary tracts of adult laboratory-raised Queensland fruit flies (Bactrocera tryoni) although the insects had ingested large numbers of live bacteria as part of their diet. The mean number of bacteria (about 13 million) present in the gut of the insects from 12 to 55 days after emergence was not significantly modified when, at 5 days after emergence, the flies were fed antibiotic-resistant bacteria belonging to two species commonly isolated from the gut of field-collected B. tryoni. Flies were fed one marked dinitrogen-fixing strain each of either Klebsiella oxytoca or Enterobacter cloacae, and the gastrointestinal tracts of fed flies were shown to be colonized within 7 days by antibiotic-resistant isolates of K. oxytoca but not E. cloacae. The composition of the microbial population also appeared to be stable in that the distribution and frequency of bacterial taxa among individual flies exhibited similar patterns whether or not the flies had been bacteria fed. Isolates of either E. cloacae or K. oxytoca, constituting 70% of the total numbers, were usually dominant, with oxidative species including pseudomonads forming the balance of the population. Antibiotic-resistant bacteria could be spread from one cage of flies to the adjacent surfaces of a second cage within a few days and had reached a control group several meters distant by 3 weeks. Restriction of marked bacteria to the population of one in five flies sampled from the control group over the next 30 days suggested that the bacterial population in the gut of the insect was susceptible to alteration in the first week after emergence but that thereafter it entered a steady state and was less likely to be perturbed by the introduction of newly encountered strains. All populations sampled, including controls, included at least one isolate of the dinitrogen-fixing family Enterobacteriaceae; many were distinct from the marked strains fed to the

    A survey of the myxosporean fauna of Australian marine fishes revealed the presence of three previously unreported species of Unicapsula (Multivalvulida: Trilosporidae) from sites off Southeast Queensland, off Lizard Island on the Great Barrier Reef, Queensland, and from Jurien Bay in Western Australia. Morphometric data (spore, polar capsule and caudal appendage dimensions) combined with Bayesian inference and maximum likelihood analyses of small subunit (SSU) and large subunit (LSU) ribosomal DNA (rDNA) were used for species identification and to explore relationships among these taxa. The four species of Unicapsula for which DNA data are now available for comparative purposes (Unicapsula andersenae n. sp., Unicapsula pflugfelderi, Unicapsula seriolae and Unicapsula pyramidata) formed a well-supported monophyletic sister clade to the other major multivalvulidan group, the Kudoidae. The combined morphometric and genetic diagnostic approach identified an undescribed taxon, U. andersenae n. sp., from the muscle of Argyrosomus japonicus, Acanthopagrus australis and Eleutheronema tetradactylum off the Southeast Queensland coast and in Lutjanus russellii and Sillago ciliata off Lizard Island. Intra-specific variation within U. andersenae n. sp. varied from 2-4 (0.2-0.4%) nucleotides over the SSU region to 2-20 (0.3-3.2%) over the LSU region. Inter-specific variation between U. andersenae n. sp. and the other three species for which genetic sequence data are now available ranged from 15-66 (3-6.5%) nucleotides over the SSU region to 103-120 (17.6-21.2%) nucleotides over the LSU region. The host distribution observed here for U. andersenae n. sp. (five fish species from five different fish families) represents the broadest specificity known for a single species of Unicapsula. U. pyramidata Naidjenova & Zaika 1970, whose spore morphology and presence of caudal appendages immediately distinguish it from other species, was recovered from the nemipterid, Scolopsis monogramma

    Terrestrial runoff and flooding have resulted in major impacts on coral communities worldwide, but we lack detailed understanding of flood plume conditions and their ecological effects. Over the course of repeated flooding between 2010 and 2013, we measured coral cover and water quality on the high-latitude coral reefs of Hervey Bay, Queensland, Australia. In 2013, salinity, total suspended solids, total nitrogen and total phosphorus were altered for up to six months post-flooding. Submarine groundwater caused hypo-saline conditions for a further four months. Despite the greater magnitude of flooding in 2013, declines in coral abundance (∼28%) from these floods were lower than the 2011 flood (∼40%), which occurred immediately after a decade of severe drought. There was an overall cumulative decrease of coral by ∼56% from 2010 to 2013. Our study highlights the need for local scale monitoring and research to facilitate informed management and conservation of catchments and marine environments.

    Estimates of long-term, background sediment generation rates place current and future sediment fluxes to the Great Barrier Reef in context. Without reliable estimates of sediment generation rates and without identification of the sources of sediment delivered to the reef prior to European settlement (c. 1850), determining the necessity and effectiveness of contemporary landscape management efforts is difficult. Using the ~2100-km2 Barron River catchment in Queensland, Australia, as a test case, we use in situ-produced 10Be to derive sediment generation rate estimates and use in situ and meteoric 10Be to identify the source of that sediment, which enters the Coral Sea near Cairns. Previous model-based calculations suggested that background sediment yields were up to an order of magnitude lower than contemporary sediment yields. In contrast, in situ 10Be data indicate that background (43 t km-2 y-1) and contemporary sediment yields (~45 t km-2 y-1) for the Barron River are similar. These data suggest that the reef became established in a sediment flux similar to what it receives today. Since western agricultural practices increased erosion rates, large amounts of sediment mobilized from hillslopes during the last century are probably stored in Queensland catchments and will eventually be transported to the coast, most likely in flows triggered by rare but powerful tropical cyclones that were more common before European settlement and may increase in strength as climate change warms the south Pacific Ocean. In situ and meteoric 10Be concentrations of Coral Sea beach sand near Cairns are similar to those in rivers on the Atherton Tablelands, suggesting that most sediment is derived from the extensive, low-gradient uplands rather than the steep, more rapidly eroding but beach proximal escarpment.

    The majority of Australia’s coal seam gas (CSG) reserves are in Queensland, where the industry has expanded rapidly in recent years. Despite concerns, health data have not been examined alongside CSG development. This study examined hospitalisation rates as a function of CSG development activity in Queensland, during the period 1995–2011. Admissions data were examined with CSG well numbers, which served as a proxy for CSG development activity. Time series models were used to assess changes in hospitalisation rates for periods of “low”, “medium”, “high”, and “intense” activity compared to a period of “very low” activity, adjusting for covariates. “All-cause” hospitalisation rates increased monotonically with increasing gas well development activity in females (324.0 to 390.3 per 1000 persons) and males (294.2 to 335.4 per 1000 persons). Hospitalisation rates for “Blood/immune” conditions generally increased for both sexes. Female and male hospitalisation rates for “Circulatory” conditions decreased with increasing CSG activity. Hospitalisation rates were generally low for reproductive and birth outcomes; no clear associations were observed. This study showed some outcomes were associated with increasing CSG development activity. However, as a condition of data access, the population and outcomes were aggregated to a broad geographic study area rather than using higher geographic resolution data. Higher resolution data, as well as other data sources, should be explored. Further research should be conducted with an expanded time period to determine if these trends continue as the industry grows. PMID:28524113

    The present paper reports on a quality improvement activity examining implementation of A Better Choice Healthy Food and Drink Supply Strategy for Queensland Health Facilities (A Better Choice). A Better Choice is a policy to increase supply and promotion of healthy foods and drinks and decrease supply and promotion of energy-dense, nutrient-poor choices in all food supply areas including food outlets, staff dining rooms, vending machines, tea trolleys, coffee carts, leased premises, catering, fundraising, promotion and advertising. An online survey targeted 278 facility managers to collect self-reported quantitative and qualitative data. Telephone interviews were sought concurrently with the twenty-five A Better Choice district contact officers to gather qualitative information. Public sector-owned and -operated health facilities in Queensland, Australia. One hundred and thirty-four facility managers and twenty-four district contact officers participated with response rates of 48.2% and 96.0%, respectively. Of facility managers, 78.4% reported implementation of more than half of the A Better Choice requirements including 24.6% who reported full strategy implementation. Reported implementation was highest in food outlets, staff dining rooms, tea trolleys, coffee carts, internal catering and drink vending machines. Reported implementation was more problematic in snack vending machines, external catering, leased premises and fundraising. Despite methodological challenges, the study suggests that policy approaches to improve the food and drink supply can be implemented successfully in public-sector health facilities, although results can be limited in some areas. A Better Choice may provide a model for improving food supply in other health and workplace settings.

    In far northern Queensland (FNQ) there are only sporadic coral and speleothem precipitation proxy records, and only one annually resolved, terrestrial record of rainfall that predates 1850 CE. Black kauri pine, Agathis atropurpurea, is a large conifer present in isolated stands near 1000 masl in the wet tropical dividing range of FNQ. Little is known about its phenology or responses to climate, although its presence near the elevational limit of the dividing range may hinder its ability to respond to increased temperature or decreased precipitation through elevational migration. We hypothesize that in this energy-limited forest, increased (decreased) solar radiation leads to increased (decreased) ring widths, and higher (lower) evapotranspiration rates produce increases (decreases) in the oxygen isotopic composition (δ18O) of the a-cellulose component of wood. To test this hypothesis, we collected over 60 cores from 21 large (dbh = 56 to 186 cm) A. atropurpurea trees from Spurgeon Peak National Park. The resulting tree-ring chronology extends from 2013 to 1438 CE and shows high average mean sensitivity (0.642) although expressed population signal drops off at 1650 CE as sample depth decreases. Comparison of the most recent 100 years of ring widths and direct climate observations show a significant positive relationship (r2 = 0.4, p < 0.01) to PDSI in December through March, coinciding with the austral rainy season associated with onset of the northern Australian Monsoon. Annualized δ18Oxygen (a-cellulose) maxima for 1983-2013 show strong and significant spatial positive relationships to Tmax and Pacific seasurface temperatures. Work to refine the interpretation of the data is onoing, but the resulting dataset may enable extension of the terrestrial climate record of north Queensland two centuries beyond current tree-ring proxies and historical observations.

    To document nutritional status and health behaviours of young indigenous women of childbearing age in rural communities in north Queensland. Cross-sectional survey of 424 Aboriginal and 232 Torres Strait Islander (TSI) women aged 15-34 years, conducted in twenty-three rural and remote communities of far north Queensland in 1999-2000, with follow-up of a smaller cohort (n 132) in 2006-2007. Weight, waist circumference, intake of fruit and vegetables, smoking, alcohol intake, fasting blood glucose, blood pressure, HDL cholesterol, gamma-glutamyltransferase, red cell folate (RCF), interval weight and waist gain and incidence of diabetes. Forty-one per cent of Aboriginal and 69 % of TSI had central obesity, 62 % were smokers, 71 % drank alcohol regularly and of those, 60 % did so at harmful levels. One third of Aboriginal and 16 % of TSI women had very low RCF levels. In the group followed up, there was a mean annual waist gain of 1.6 cm in Aboriginal women and 1.2 cm in TSI, 0.5 kg/m2 in BMI and 1.5 kg in weight. Incidence of new type 2 diabetes mellitus in this cohort was 29.1 per 1000 person-years (py) (95 % CI 14.0, 52.8) in Aboriginal women and 13.9 per 1000 py (95 % CI 5.6, 28.5) among TSI. High prevalence and incidence of central obesity and diabetes, poor nutrition, high rates of alcohol use and tobacco smoking together with young maternal age, provide a poor intra-uterine environment for many indigenous Australian babies, and contribute to high perinatal morbidity and future disability. Community level interventions to improve pre-pregnancy nutrition and health behaviours in young women are urgent.

    Following the introduction of vaccination against Haemophilus influenzae type b (Hib), cases of invasive encapsulated Hib disease have decreased markedly. This study aimed to examine subsequent epidemiological trends in invasive H. influenzae disease in Queensland, Australia and in particular, assess the clinical impact and public health implications of invasive non-typable H. influenzae (NTHi) strains. A multicentre retrospective study was conducted from July 2000 to June 2013. Databases of major laboratories in Queensland including Queensland Forensic and Scientific Services (jurisdictional referral laboratory for isolate typing) were examined to identify cases. Demographic, infection site, Indigenous status, serotype, and mortality data were collected. In total, 737 invasive isolates were identified, of which 586 (79·5%) were serotyped. Hib, NTHi and encapsulated non-b strains, respectively, constituted 12·1%, 69·1% and 18·8% of isolates. The predominant encapsulated non-b strains were f (45·5%) and a (27·3%) serotypes. Of isolates causing meningitis, 48·9% were NTHi, 14·9% Hib, 14·9% Hie, 10·6% Hif, 6·4% Hia and 4·3% were untyped. During the study period, there was an increase in the incidence of invasive NTHi disease (P = 0·007) with seasonal peaks in winter and spring (P 0·001) and Hib (P = 0·039) than non-Indigenous patients. In Queensland, invasive H. influenzae disease is now predominantly encountered in adults and most commonly caused by NTHi strains with demonstrated pathogenicity extending to otherwise young or immunocompetent individuals. Routine public health notification of these strains is recommended and recent available immunization options should be considered.

    To evaluate clinical healthcare performance in Aboriginal Medical Services in Queensland and to consider future directions in supporting improvement through measurement, target setting and standards development. Longitudinal study assessing baseline performance and improvements in service delivery, clinical care and selected outcomes against key performance indicators 2009-2010. 27 Aboriginal and Islander Community Controlled Health Services (AICCHSs) in Queensland, who are members of the Queensland Aboriginal and Islander Health Council (QAIHC). 22 AICCHS with medical clinics. Implementation and use of an electronic clinical information system that integrates with electronic health records supported by the QAIHC quality improvement programme-the Close the Gap Collaborative. Proportion of patients with current recording of key healthcare activities and the prevalence of risk factors and chronic disease. Aggregated performance was high on a number of key risk factors and healthcare activities including assessment of tobacco use and management of hypertension but low for others. Performance between services showed greatest variation for care planning and health check activity. Data collected by the QAIHC health information system highlight the risk factor workload facing the AICCHS in Queensland, demonstrating the need for ongoing support and workforce planning. Development of targets and weighting models is necessary to enable robust between-service comparisons of performance, which has implications for health reform initiatives in Australia. The limited information available suggests that although performance on key activities in the AICCHS sector has potential for improvement in some areas, it is nonetheless at a higher level than for mainstream providers. The work demonstrates the role that the Community Controlled sector can play in closing the gap in Aboriginal and Torres Strait Islander health outcomes by leading the use of clinical data to record and assess

    Full Text Available To redress the lack of Queensland population incidence mortality and morbidity data associated with drowning in those aged 0-19 yrs, and to understand survival and patient care.Retrospective population-based study used data linkage to capture both fatal and non-fatal drowning cases (N = 1299 among children aged 0-19 years in Queensland, from 2002-2008 inclusive. Patient data were accessed from pre-hospital, emergency department, hospital admission and death data, and linked manually to collate data across the continuum of care.Incidence rates were calculated separately by age group and gender for events resulting in death, hospital admission, and non-admission. Trends over time were analysed.Drowning death to survival ratio was 1:10, and two out of three of those who survived were admitted to hospital. Incidence rates for fatal and non-fatal drowning increased over time, primarily due to an increase in non-fatal drowning. There were non-significant reductions in fatal and admission rates. Rates for non-fatal drowning that did not result in hospitalisation more than doubled over the seven years. Children aged 5-9 yrs and 10-14 yrs incurred the lowest incidence rates 6.38 and 4.62 (expressed as per 100,000, and the highest rates were among children aged 0-4 yrs (all drowning events 43.90; fatal 4.04; non-fatal 39.85-comprising admission 26.69 and non-admission 13.16. Males were over-represented in all age groups except 10-14 yrs. Total male drowning events increased 44% over the seven years (P<0.001.This state-wide data collection has revealed previously unknown incidence and survival ratios. Increased trends in drowning survival rates may be viewed as both positive and challenging for drowning prevention and the health system. Males are over-represented, and although infants and toddlers did not have increased fatality rates, they had the greatest drowning burden demonstrating the need for continued drowning prevention efforts.

    This study seeks to add to current literature a descriptive account of the lived experience of radiographers' transition to, and experiences of, management roles and identifies additional resources and support that are perceived as being beneficial for this transition. This study employed a descriptive phenomenological stance. Using purposive sampling, six South-East Queensland based private practice radiology managers, who had held their position for longer than 3 months, participated in audiotape recorded in-depth interviews exploring their transition to, and experiences of management in radiology. Thematic analysis was used to describe and make meaning of the data. Overall, five central themes emerged through thematic analysis of the data. The results indicate that all participants' had an underlying drive to succeed during their role transition and highlight the importance of a comprehensive orientation by a mentor; the training and support to enable preparation for the role, especially in the area of people management skills and communication; the importance of access to networking opportunities and the importance of concise expectations from higher management. Role transition can be marred with uncertainty, however; key suggestions indicate the importance of having support mechanisms in place before, during and after transitioning to a managerial role.

    2014-03-01

    Ediea homevalensis H. Nishida, Kudo, Pigg & Rigby gen. et sp. nov. is proposed for permineralized pollen-bearing structures from the Late Permian Homevale Station locality of the Bowen Basin, Queensland, Australia. The taxon represents unisexual fertile shoots bearing helically arranged leaves on a central axis. The more apical leaves are fertile microsporophylls bearing a pair of multi-branched stalks on their adaxial surfaces that each supports a cluster of terminally borne pollen sacs. Proximal to the fertile leaves there are several rows of sterile scale-like leaves. The pollen sacs (microsporangia) have thickened and dark, striate walls that are typical of the Arberiella type found in most pollen organs presumed to be of glossopterid affinity. An examination of pollen organs at several developmental stages, including those containing in situ pollen of the Protohaploxypinus type, provides the basis for a detailed analysis of these types of structures, which bear similarities to both compression/impression Eretmonia-type glossopterid microsporangiate organs and permineralized Eretmonia macloughlinii from Antarctica. These fossils demonstrate that at least some Late Permian pollen organs were simple microsporophyll-bearing shoot systems and not borne directly on Glossopteris leaves.

    In this study, the host-sensitivity and host-specificity of JC virus (JCV) and BK virus (BKV) polyomaviruses were evaluated by testing wastewater and fecal samples from nine host groups in Southeast Queensland, Australia. The JCV and BKV polyomaviruses were detected in 63 human wastewater samples collected from primary and secondary effluent, suggesting high sensitivity of these viruses in human wastewater. In the 81 animal wastewater and fecal samples tested, 80 were polymerase chain reaction (PCR) negative for the JCV and BKV markers. Only one sample (out of 81 animal wastewater and fecal samples) from pig wastewater was positive. Nonetheless, the overall host-specificity of these viruses to differentiate between human and animal wastewater and fecal samples was 0.99. To our knowledge, this is the first study in Australia that reports on the high specificity of JCV and BKV polyomaviruses. To evaluate the field application of these viral markers for detecting human fecal pollution, 20 environmental samples were collected from a coastal river. In the 20 samples tested, 15% (3/20) and 70% (14/20) samples exceeded the regulatory guidelines for Escherichia coli and enterococci levels for marine waters. In all, five (25%) samples were PCR positive for JCV and BKV, indicating the presence of human fecal pollution in the coastal river investigated. The results suggest that JCV and BKV detection using PCR could be a useful tool for identifying human-sourced fecal pollution in coastal waters.

    Full Text Available Organic compounds in Australian coal seam gas produced water (CSG water are poorly understood despite their environmental contamination potential. In this study, the presence of some organic substances is identified from government-held CSG water-quality data from the Bowen and Surat Basins, Queensland. These records revealed the presence of polycyclic aromatic hydrocarbons (PAHs in 27% of samples of CSG water from the Walloon Coal Measures at concentrations <1 µg/L, and it is likely these compounds leached from in situ coals. PAHs identified from wells include naphthalene, phenanthrene, chrysene and dibenz[a,h]anthracene. In addition, the likelihood of coal-derived organic compounds leaching to groundwater is assessed by undertaking toxicity leaching experiments using coal rank and water chemistry as variables. These tests suggest higher molecular weight PAHs (including benzo[a]pyrene leach from higher rank coals, whereas lower molecular weight PAHs leach at greater concentrations from lower rank coal. Some of the identified organic compounds have carcinogenic or health risk potential, but they are unlikely to be acutely toxic at the observed concentrations which are almost negligible (largely due to the hydrophobicity of such compounds. Hence, this study will be useful to practitioners assessing CSG water related environmental and health risk.

    Biting midges are globally distributed pests causing significant economic losses and transmitting arbovirus diseases to both animals and humans. Current biological and chemical control strategies for biting midge target destruction of adult forms, but strategies directed at immature stages of the insect have yet to be explored in Australia. In the present study, coastal waters of Hervey Bay region in Queensland, Australia were screened to detect the habitats of biting midge at immature stages. These results were then correlated to local environmental conditions and naturally occurring entomopathogenic fungal flora, in particular the Oomycete fungi, to determine their reducing effect on insect immature stages in the search for biological control agents in the region. The dominant species of biting midge found within this study was Culicoides subimmaculatus occuring between mean high water neaps and mean high water spring tide levels. Within this intertidal zone, the presence of C. subimmaculatus larvae was found to be influenced by both sediment size and distance from shore. Halophytophthora isolates colonized both dead and alive pupae. However, the association was found to be surface colonization rather than invasion causing the death of the host. Lack of aggressive oomycete fungal antagonists towards midge larvae might correlate with increased incidences of biting midge infestations in the region.

    Reflecting trends in medical education from didactic teaching to student-centred learning, the novel approach of student-led learning was applied at the University of Queensland (UQ) School of Medicine. This article examines the benefits, risks and limitations of curriculum development led by students. The Project aimed to trial student-led development of a Global Health curriculum module for the UQ medical programme, as part of an international collaboration with related Health Sciences activities of Universitas 21 (U21). The Head (Dean) of the UQ School of Medicine instigated the Project. A student Convenor was appointed to lead it and, in conjunction with faculty, to design curriculum Learning Objectives and supporting resources. The initial vision of the Project was greatly expanded, from an optional elective to a compulsory curriculum module with inbuilt prospective outcome measures. The module was established in less than 12 months and is now being delivered throughout the 4-year medical programme. A process for ongoing student leadership of the Project was established. Student-led learning can be effective if given adequate support by faculty. The UQ School of Medicine's new curriculum module and collaboration with U21 promote the teaching of Global Health.

    Two new species of Fergusobia, collected from 'rosette' shoot bud galls on Melaleuca quinquenervia, and from leaf, stem, leaf and flower bud galls on Syzygium luehmannii, both from the Cairns region of Queensland, Australia, are described. Fergusobia rosettae Davies n. sp. is characterised by the combination of a small, arcuate parthenogenetic female having a short conoid tail with a bluntly rounded tip, an arcuate, relatively slender, infective female with an almost hemispherical tail tip, and arcuate males with arcuate to angular (not heavily sclerotised) spicules and leptoderan bursa arising at 40-50% of body length from tail tip. Fergusobia tolgaensis Davies n. sp. is characterised by the combination of a small open C-shaped parthenogenetic female with a broadly conoid tail, an arcuate infective female with a broadly rounded tail tip, and arcuate males with angular (not heavily sclerotised) spicules and short to mid-length leptoderan bursa. These two species of nematodes are associated with fly larvae that have dorsal shields comprising bars of raised cuticular ridges and spicules, similar to that of fly larvae from the M. leucadendra species group. The shield morphologies of these fly larvae and their possible genetic relationships are discussed. Possible evolutionary relationships of the Fergusobia nematodes from these galls are discussed, considering their morphology, DNA sequences, and the relationships of the associated Fergusonina flies and host plants.

    The Winton Formation of central Queensland is recognized as a quintessential source of mid-Cretaceous terrestrial faunas and floras in Australia. However, sedimentological investigations linking fossil assemblages and palaeoenvironments across this unit remain limited. The intent of this study was to interpret depositional environments and improve stratigraphic correlations between multiple fossil localities within the preserved Winton Formation in the Eromanga Basin, including Isisford, Lark Quarry, and Bladensburg National Park. Twenty-three facies and six repeated facies associations were documented, indicating a mosaic of marginal marine to inland alluvial depositional environments. These developed synchronously with the final regression of the Eromanga Seaway from central Australia during the late Albian-early Turonian. Investigations of regional- and local-scale structural features and outcrop, core and well analysis were combined with detrital zircon provenance signatures to help correlate stratigraphy and vertebrate faunas across the basin. Significant palaeoenvironmental differences exist between the lower and upper portions of the preserved Winton Formation, warranting informal subdivisions; a lower tidally influenced fluvial-deltaic member and an upper inland alluvial member. This work further demonstrates that the Isisford fauna is part of the lower member of the preserved Winton Formation; whereas, fossil localities around Winton, including Lark Quarry and Bladensburg National Park, are part of the upper member of the Winton Formation. These results permit a more meaningful framework for both regional and global comparisons of the Winton flora and fauna.

    After a disaster, the media typically focus on who is to blame. However, relatively little is known about how the narrative of blame plays out in media coverage of the release of official disaster reports. This paper examines coverage by two Australian newspapers (The Courier-Mail and The Australian) of the release of the Queensland Floods Commission of Inquiry's Interim Report and its Final Report to identify whether and how the news frame of blame was used. Given the absence of blame in the Final Report, the newspapers resorted to the frame of 'failure' in news and feature articles, while continuing to raise questions in editorials and opinion pieces about who was to blame. This study argues that situating coverage of the report within the news frame of failure and questioning who was to blame for the disaster limited the media's ability to facilitate a discussion about the prevention of similar disasters in the future. © 2014 The Author(s).

    Full Text Available Minmi is the only known genus of ankylosaurian dinosaur from Australia. Seven specimens are known, all from the Lower Cretaceous of Queensland. Only two of these have been described in any detail: the holotype specimen Minmi paravertebra from the Bungil Formation near Roma, and a near complete skeleton from the Allaru Mudstone on Marathon Station near Richmond, preliminarily referred to a possible new species of Minmi. The Marathon specimen represents one of the world’s most complete ankylosaurian skeletons and the best-preserved dinosaurian fossil from eastern Gondwana. Moreover, among ankylosaurians, its skull is one of only a few in which the majority of sutures have not been obliterated by dermal ossifications or surface remodelling. Recent preparation of the Marathon specimen has revealed new details of the palate and narial regions, permitting a comprehensive description and thus providing new insights cranial osteology of a basal ankylosaurian. The skull has also undergone computed tomography, digital segmentation and 3D computer visualisation enabling the reconstruction of its nasal cavity and endocranium. The airways of the Marathon specimen are more complicated than non-ankylosaurian dinosaurs but less so than derived ankylosaurians.

    Minmi is the only known genus of ankylosaurian dinosaur from Australia. Seven specimens are known, all from the Lower Cretaceous of Queensland. Only two of these have been described in any detail: the holotype specimen Minmi paravertebra from the Bungil Formation near Roma, and a near complete skeleton from the Allaru Mudstone on Marathon Station near Richmond, preliminarily referred to a possible new species of Minmi. The Marathon specimen represents one of the world's most complete ankylosaurian skeletons and the best-preserved dinosaurian fossil from eastern Gondwana. Moreover, among ankylosaurians, its skull is one of only a few in which the majority of sutures have not been obliterated by dermal ossifications or surface remodelling. Recent preparation of the Marathon specimen has revealed new details of the palate and narial regions, permitting a comprehensive description and thus providing new insights cranial osteology of a basal ankylosaurian. The skull has also undergone computed tomography, digital segmentation and 3D computer visualisation enabling the reconstruction of its nasal cavity and endocranium. The airways of the Marathon specimen are more complicated than non-ankylosaurian dinosaurs but less so than derived ankylosaurians. The cranial (brain) endocast is superficially similar to those of other ankylosaurians but is strongly divergent in many important respects. The inner ear is extremely large and unlike that of any dinosaur yet known. Based on a high number of diagnostic differences between the skull of the Marathon specimen and other ankylosaurians, we consider it prudent to assign this specimen to a new genus and species of ankylosaurian. Kunbarrasaurus ieversi gen. et sp. nov. represents the second genus of ankylosaurian from Australia and is characterised by an unusual melange of both primitive and derived characters, shedding new light on the evolution of the ankylosaurian skull.

    Along low gradient rivers in northern Australia, there is widespread gully erosion into unconfined alluvial deposits of active and inactive floodplains. On the Mitchell River fluvial megafan in northern Queensland, river incision and fan-head trenching into Pleistocene and Holocene megafan units with sodic soils created the potential energy for a secondary cycle of erosion. In this study, rates of alluvial gully erosion into incipiently-unstable channel banks and/or pre-existing floodplain features were quantified to assess the influence of land use change following European settlement. Alluvial gully scarp retreat rates were quantified at 18 sites across the megafan using recent GPS surveys and historic air photos, demonstrating rapid increases in gully area of 1.2 to 10 times their 1949 values. Extrapolation of gully area growth trends backward in time suggested that the current widespread phase of gullying initiated between 1880 and 1950, which is post-European settlement. This is supported by young optically stimulated luminescence (OSL) dates of gully inset-floodplain deposits, LiDAR terrain analysis, historic explorer accounts of earlier gully types, and archival records of cattle numbers and land management. It is deduced that intense cattle grazing and associated disturbance concentrated in the riparian zones during the dry season promoted gully erosion in the wet season along steep banks, adjacent floodplain hollows and precursor gullies. This is a result of reduced native grass cover, increased physical disturbance of soils, and the concentration of water runoff along cattle tracks, in addition to fire regime modifications, episodic drought, and the establishment of exotic weed and grass species. Geomorphic processes operating over geologic time across the fluvial megafan predisposed the landscape to being pushed by land used change across an intrinsically close geomorphic threshold towards instability. The evolution of these alluvial gullies is discussed

    Reducing the prevalence of obesity and chronic disease are important priorities. Maori and Pacific Islander communities living in Australia have higher rates of obesity and chronic disease than the wider Australian population. This study aims to assess the effectiveness of the Good Start program, which aims to improve knowledge, attitudes and practices related to healthy eating and physical activity amongst Maori and Pacific Islander communities living in Queensland. The intervention was delivered to children aged 6-19 years (N = 375) in schools by multicultural health workers. Class activities focused on one message each term related to healthy eating and physical activity using methods such as cooking sessions and cultural dance. The evaluation approach was a quantitative uncontrolled pre-post design. Data were collected each term pre- and post-intervention using a short questionnaire. There were significant increases in knowledge of correct servings of fruit and vegetables, knowledge of sugar and caffeine content of common sugar-sweetened drinks, recognition of the consequences of marketing and upsizing, and the importance of controlling portion size (all P activity recommendations (P activity for preventing heart disease (P junk food may be beneficial. The study has shown that the Good Start Program was effective in engaging children from Maori and Pacific Island backgrounds and in improving knowledge, and some attitudes and practices, related to healthy eating and physical activity. The evaluation contributes valuable information about components and impacts of this type of intervention, and considerations relevant to this population in order to successfully change behaviours and reduce the burden of chronic disease.

  11. How much does it cost to expand a protected area system? Some critical determining factors and ranges of costs for Queensland.

    Vanessa M Adams

    Full Text Available Many governments have recently gone on record promising large-scale expansions of protected areas to meet global commitments such as the Convention on Biological Diversity. As systems of protected areas are expanded to be more comprehensive, they are more likely to be implemented if planners have realistic budget estimates so that appropriate funding can be requested. Estimating financial budgets a priori must acknowledge the inherent uncertainties and assumptions associated with key parameters, so planners should recognize these uncertainties by estimating ranges of potential costs. We explore the challenge of budgeting a priori for protected area expansion in the face of uncertainty, specifically considering the future expansion of protected areas in Queensland, Australia. The government has committed to adding ∼12 million ha to the reserve system, bringing the total area protected to 20 million ha by 2020. We used Marxan to estimate the costs of potential reserve designs with data on actual land value, market value, transaction costs, and land tenure. With scenarios, we explored three sources of budget variability: size of biodiversity objectives; subdivision of properties; and legal acquisition routes varying with tenure. Depending on the assumptions made, our budget estimates ranged from $214 million to $2.9 billion. Estimates were most sensitive to assumptions made about legal acquisition routes for leasehold land. Unexpected costs (costs encountered by planners when real-world costs deviate from assumed costs responded non-linearly to inability to subdivide and percentage purchase of private land. A financially conservative approach--one that safeguards against large cost increases while allowing for potential financial windfalls--would involve less optimistic assumptions about acquisition and subdivision to allow Marxan to avoid expensive properties where possible while meeting conservation objectives. We demonstrate how a rigorous

    Full Text Available Feral pigs (Sus scrofa are an invasive species that disrupt ecosystem functioning throughout their introduced range. In tropical environments, feral pigs are associated with predation and displacement of endangered species, modification of habitat, and act as a vector for the spread of exotic vegetation and disease. Across many parts of their introduced range, the diet of feral pigs is poorly known. Although the remote location and difficult terrain of far north Queensland makes observing feral pig behavior difficult, feral pigs are perceived to seek refuge in World Heritage tropical rainforests and seasonally 'crop raid' into lowland sugarcane crops. Thus, identifying how feral pigs are using different components of the landscape is important to the design of management strategies. We used the stable isotope composition of captured feral pigs to determine the extent of rainforest and sugarcane habitat usage. Recently grown hair (basal hair from feral pigs captured in remote rainforest indicated pigs met their dietary needs solely within this habitat. Stable carbon and nitrogen isotope values of basal hair from feral pigs captured near sugarcane plantations were more variable, with some individuals estimated to consume over 85% of their diet within a sugarcane habitat, while a few consumed as much as 90% of their diet from adjacent forested environments. We estimated whether feral pigs switch habitats by sequentially sampling δ(13C and δ(15N values of long tail hair from a subset of seven captured animals, and demonstrate that four of these individuals moved between habitats. Our results indicate that feral pigs utilize both sugarcane and forest habitats, and can switch between these resources.

    Granitic plutons of the Wangetti and Mt Formartine Supersuites intrude the Hodgkinson Formation of the Macalister Range district of the eastern Hodgkinson Province, north Queensland, Australia. Field and microstructural analyses of country-rock fabrics and those of the granites show four deformational events (D{sub 1}-D{sub 4}) for the district, in common with other sectors of the Hodgkinson Province. Structural relationships show that plutons of the two supersuites were emplaced at different times. The Wangetti Granite lacks fabric development, but the deflection of country-rock cleavage trends around it and the microscale crenulation of S{sub 2} on the rims of D{sub 4} porphyroblasts within its aureole indicate syn-D{sub 4} emplacement, consistent with the Early Permian crystallisation age attributed to this pluton from isotopic evidence. Plutons of the Mt Formartine Supersuite show the effects of multiple (D{sub 2}-D{sub 4}) deformation. An emplacement age of 357 {+-} 6 Ma (latest Devonian) was obtained for this granite by SHRIMP U-Pb analyses of zircon. This identifies an early episode of plutonism for the Hodgkinson Province, most granites from which are of Permian age. The new date constrains the age of D{sub 2} for the Macalister Range district and the age of the protolith of the Hodgkinson Formation as pre-Carboniferous. It matches the age previously determined for one of several small, related granitic stocks in the southeastern Camel Creek Subprovince of the Broken River Province. Structural relationships for granites of this age suggest that their emplacement was broadly associated with the first episode of regional-scale orogenesis and the development of penetrative fabrics in the Hodgkinson - Broken River Fold Belt.

    A total of 515 yeast strains were isolated from the nasal smears of Queensland koalas and their breeding environments in Japanese zoological parks between 2005 and 2012. The most frequent species in the basidiomycetous yeast biota isolated from koala nasal passages was Cryptococcus neoformans, followed by Rhodotorula minuta. R. minuta was the most frequent species in the breeding environments, while C. neoformans was rare. Seven strains representing two novel yeast species were identified. Analyses of the 26S rDNA (LSU) D1/D2 domain and nuclear ribosomal DNA internal transcribed spacer region sequences indicated that these strains represent new species with close phylogenetic relationships to Cryptococcus and Rhodotorula. A sexual state was not found for either of these two novel yeasts. Key phenotypic characters confirmed that these strains could be placed in Cryptococcus and Rhodotorula. The names Cryptococcus lacticolor sp. nov. (type strain TIMM 10013(T) = JCM 15449(T) = CBS 10915(T) = DSM 21093(T), DDBJ/EMBL/Genbank Accession No.; AB375774 (ITS) and AB375775 (26S rDNA D1/D2 region), MycoBank ID; MB 802688, Fungal Barcoding Database ID; 3174), and Rhodotorula oligophaga sp. nov.

    Introduction Appropriate dietary iodine is essential for thyroid hormone synthesis, especially in young children. Following an iodine fortification in bread initiative, approximately 6 % of Australian preschool children were expected to have an excessive iodine status. The aim of this study was to document the current iodine status of preschool children using urinary iodine concentration (UIC) as a biomarker of iodine intake. Methods A convenience sample of fifty-one preschool children, aged 2-3 years, were recruited from south east Queensland. UIC was ascertained from spot morning and afternoon urine samples collected on two consecutive days and food frequency questionnaires were completed for each participant. Dietary iodine intake was extrapolated from UIC assuming 90 % of dietary iodine is excreted in urine and a urine volume of 0.5 L/day. Results A median UIC of 223.3 μg/L was found. The calculated median dietary iodine intake was 124.8 μg/day (SD 47.0) with 9.8 % of samples above the upper level of 200 μg for dietary iodine for children within this age group. No foods were associated with UIC. Discussion Limited by sample size and recruitment strategies, no association was found between usual food intake and UIC. Extrapolated dietary iodine intake indicated that children within this cohort consumed adequate amounts of dietary iodine, although the number of children consuming above the upper limit of 300 μg/day was almost double of expected. The development of a UIC criteria to assess appropriate parameters for varying degrees of iodine status is required for the monitoring of iodine nutrition in this vulnerable age group.

    The Institute for Urban Indigenous Health believes that continuous quality improvement (CQI) contributes to the delivery of high-quality care, thereby improving health outcomes for Aboriginal and Torres Strait Islander people. The opening of a new health service in 2015 provided an opportunity to implement best practice CQI strategies and apply them to a regional influenza vaccination campaign. The aim of this project was to implement an evidence-based CQI process within one Aboriginal Community Controlled Health Service in South East Queensland and use staff engagement as a measure of success. A CQI tool was selected from the Joanna Briggs Institute Practical Application of Clinical Evidence System (PACES) to be implemented in the study site. The study site was a newly established Aboriginal and Torres Strait Islander Community Controlled Health Service located in the northern suburbs of Brisbane. This project used the evidence-based information collected in PACES to develop a set of questions related to known variables resulting in proven CQI uptake. A pre implementation clinical audit, education and self-directed learning, using the Plan Do Study Act framework, included a total of seven staff and was conducted in April 2015. A post implementation audit was conducted in July 2015. There were a total of 11 pre- and post-survey respondents which included representation from most of the clinical team and medical administration. The results of the pre implementation audit identified a number of possible areas to improve engagement with the CQI process including staff training and support, understanding CQI and its impacts on individual work areas, understanding clinical data extraction, clinical indicator benchmarking, strong internal leadership and having an external data extractor. There were improvements to all audit criteria in the post-survey, for example, knowledge regarding the importance of CQI activity, attendance at education and training sessions on CQI

    This study presents one of the first applications of geochemical proxies to define changes in vegetation, hydrology and atmospheric dust recorded in a peat deposit in the Southern Hemisphere. The Lynch's Crater archive has captured local, regional and global environmental changes and reveals dynamic ecosystem changes as a result of climate shifts over the past 55,000 yrs BP. The 13 m peat record consists of 1.5 m of ombrotrophic peat underlain by a minerotrophic peat. The ombrotrophic section consists of low inorganic content ("ash") and low pH, as expected in of an ombrotrophic environment. The minerotrophic section contains several layers, up to a few cm thick, where abundant sponge spicules, diatom fragments and detrital quartz are indicative of high algal and protista productivity. These layers are characterised by high (up to 50%) ash, indicating persistent flooding of the peat deposits of Lynch's Crater and signalling periods of change in precipitation in North Queensland, Australia. Geochemical data are used to differentiate between climatic episodes associated with flooding events and internal and external atmospheric dust fluxes. Lead isotopes with lithogenic and chalcophile elements tell us that two distinctive sources are prevalent in the Lynch's Crater record. Most of the inorganic fractions of the deposits have the same geochemical signatures as the rocks and sediments of the crater wall, with low As concentrations, high Al, Ti and Sc concentrations and a more radiogenic Pb isotope signature. Influence from long-range dust is distinguished in the lower sections of the core (~35,000-55,000 cal yrs BP) where increases in As concentrations and less radiogenic Pb isotopes are found. Leading up to the Holocene (~35,000-10,000) the influence of increased dust influx becomes more significant (increasing lithogenics, chalcophiles and ash content) and where possible long-range sources are still active, but diluted by a prevailing dominance of the local sources

    A spatial analysis of hydrochemical data of groundwater and surface water was undertaken to identify groundwater-surface water connectivity in the headwaters of the Condamine River catchment, Southeast Queensland, Australia. An assessment of long-term hydrochemical and water level data supplemented by stable- and radioisotope measurements following a prolonged dry period dominated by baseflow, helped in determining patterns of interaction in different tributaries of the upper Condamine catchment. A conceptual hydrological model representing the major hydrochemical processes and their implications for stream-aquifer connectivity was developed and tested using multiple lines of evidence. The results of a multivariate statistical analysis highlight that there are two main regions with distinct hydrochemical facies (salinity, alkalinity, and predominant ions) in surface water. Geomorphology, geology, anthropogenic and climate influence were identified as the most relevant controlling factors of the spatial variability in water quality. Stable isotope data confirmed a clear evaporation trend in almost all surface water samples during baseflow conditions. Two water types can be identified and separated by the degree of evaporation and the proximity of one group to the local meteoric water line. The results confirm the discharge of groundwater from aquifers recharged by rainfall and located upstream of the surface water sampling sites. Overall, {sup 222}Rn data show a trend of increased activity in surface water towards the upstream portions of these tributaries, validating the use of this tracer to estimate groundwater input to the local creeks. The proportion of groundwater contribution to stream flow calculated by {sup 222}Rn and chloride mass balance is in agreement, and ranges between 20–70% in tributaries in the northern areas, and between 8–50% in the upper reaches of the main river channel. This study shows the efficacy of an integrated approach combining long

    Lifestyle behaviours significantly contribute to high levels of chronic disease in older adults. The aims of the study were to compare the prevalence and the prevalence trends of health behaviours (physical activity, fruit and vegetable consumption, fast food consumption, TV viewing, smoking and alcohol consumption), BMI and a summary health behaviour indicator score in older (65+ years) versus younger adults (18–65 years). The self-report outcomes were assessed through the Queensland Social Survey annually between 2007–2014 (n = 12,552). Regression analyses were conducted to compare the proportion of older versus younger adults engaging in health behaviours and of healthy weight in all years combined and examine trends in the proportion of younger and older adults engaging in health behaviours and of healthy weight over time. Older adults were more likely to meet recommended intakes of fruit and vegetable (OR = 1.43, 95%CI = 1.23–1.67), not consume fast food (OR = 2.54, 95%CI = 2.25–2.86) and be non-smokers (OR = 3.02, 95%CI = 2.53–3.60) in comparison to younger adults. Conversely, older adults were less likely to meet the physical activity recommendations (OR = 0.86, 95%CI = 0.78–0.95) and watch less than 14 hours of TV per week (OR = 0.65, 95%CI = 0.58–0.74). Overall, older adults were more likely to report engaging in 3, or at least 4 out of 5 healthy behaviours. The proportion of both older and younger adults meeting the physical activity recommendations (OR = 0.97, 95%CI = 0.95–0.98 and OR = 0.94, 95%CI = 0.91–0.97 respectively), watching less than 14 hours of TV per week (OR = 0.96, 95%CI = 0.94–0.99 and OR = 0.94, 95%CI = 0.90–0.99 respectively) and who were a healthy weight (OR = 0.95, 95%CI = 0.92–0.99 and OR = 0.96, 95%CI = 0.94–0.98 respectively) decreased over time.

    Full Text Available Abstract Background Enterococcus faecalis and Enterococcus faecium are associated with faecal pollution of water, linked to swimmer-associated gastroenteritis and demonstrate a wide range of antibiotic resistance. The Coomera River is a main water source for the Pimpama-Coomera watershed and is located in South East Queensland, Australia, which is used intensively for agriculture and recreational purposes. This study investigated the diversity of E. faecalis and E. faecium using Single Nucleotide Polymorphisms (SNPs and associated antibiotic resistance profiles. Results Total enterococcal counts (cfu/ml for three/six sampling sites were above the United States Environmental Protection Agency (USEPA recommended level during rainfall periods and fall into categories B and C of the Australian National Health and Medical Research Council (NHMRC guidelines (with a 1-10% gastrointestinal illness risk. E. faecalis and E. faecium isolates were grouped into 29 and 23 SNP profiles (validated by MLST analysis respectively. This study showed the high diversity of E. faecalis and E. faecium over a period of two years and both human-related and human-specific SNP profiles were identified. 81.8% of E. faecalis and 70.21% of E. faecium SNP profiles were associated with genotypic and phenotypic antibiotic resistance. Gentamicin resistance was higher in E. faecalis (47% resistant and harboured the aac(6'-aph(2' gene. Ciprofloxacin resistance was more common in E. faecium (12.7% resistant and gyrA gene mutations were detected in these isolates. Tetracycline resistance was less common in both species while tet(L and tet(M genes were more prevalent. Ampicillin resistance was only found in E. faecium isolates with mutations in the pbp5 gene. Vancomycin resistance was not detected in any of the isolates. We found that antibiotic resistance profiles further sub-divided the SNP profiles of both E. faecalis and E. faecium.

    In this presentation, we intend to detail preliminary results and observations collected during the BIRFURCATION cruise, staged on board the R/V Alis of the IRD and operated under the auspices of SPICE (Southwest PacIfic Ocean Circulation and Climate Experiment). A specific effort during SPICE was made to establish an observational program to survey air-sea fluxes and currents in the Coral, Solomon, and Tasman Seas, and their inflows and outflows, with special attention to the strong boundary currents. During its transit into the Coral Sea, the southern branch of the Southern Equatorial Current is affected by the presence of many reefs and small islands of a coral archipelago that cause it to form intense fine-scale oceanic jets downstream of these topographic obstacles. The North Caledonian Jet formed at its entry into the Coral Sea is further separated into flows towards the South (feeding the East Australian Current) and towards the equator (through the Solomon Sea). The obstacle responsible for this separation is the plateau of Queensland, near 17°S-152°E, which is composed of a group of small islands and coral reefs that are distinct from the Great Barrier Reef. The precise pathways and the relative contributions of the various water masses that arrive at the base of this plateau are still unknown and represent the focus of BIFURCATION. This cruise should thus supplement our vision of the circulation of the North Caledonian Jet within the Coral Sea, and make it possible to test to what extent this water contributes to the composition of the current at the western edge of the New Guinea UnderCurrent which feeds the equatorial band and whose climatological mass transport is estimated in the literature to vary by a factor of 2. By determining the characteristics of these water masses before their final arrival at the Australian coast it will also be possible to estimate to what extent they undergo further mixing with yet other water masses within the Coral and

    One strategy available to public health officials during a pandemic is physician recommendations for isolation of infected individuals. This study was undertaken during the height of the Australian pandemic (H1N1) 2009 outbreak to measure self-reported willingness to comply with physician recommendations to stay home for seven days, and to compare responses for the current strain of pandemic influenza, avian influenza, seasonal influenza, and the common cold. Data were collected as part of the Queensland Social Survey (QSS) 2009, which consisted of a standardized introduction, 37 demographic questions, and research questions incorporated through a cost-sharing arrangement. Four questions related to respondents' anticipated compliance with a physician's advice to stay home if they had a common cold, seasonal influenza, pandemic (H1N1) 2009 influenza or avian influenza were incorporated into QSS 2009, with responses recorded using a balanced Likert scale ranging from "very unlikely" to "very likely." Discordance between responses for different diseases was analysed using McNemar's test. Associations between demographic variables and anticipated compliance were analysed using Pearson's chi-square or chi-square for linear-by-linear association, and confirmed using multivariate logistic regression; p compliance increased from 59.9% for the common cold to 71.3% for seasonal influenza (p compliance did not differ for pandemic (H1N1) 2009 and avian influenza (p = 0.815).

    In order to understand source of sediment and rate of erosion for Barron River catchment, which heads on the Atherton Tablelands of northeast Australia, crosses the northern Queensland escarpment and drains into the Coral Sea, we collected fluvial sediment and measured both in situ and meteoric 10Be contents on the medium sand fraction. We collected fourteen samples from rivers and streams including large regional drainages and small tributaries. The upland basins are characterized by lower relief and less precipitation than the steeper and wetter escarpment basins. One sample is quartz sand from the Coral Sea beach at Yorkey's Knob, below the escarpment. Sand from the Barron River upstream of the escarpment integrates the upland basins and has an in situ 10Be concentration of 2.31±0.84 x105atoms/g and an erosion rate of 17.2 m/My (calculated using the CRONOS on-line calculator). This is similar to a major upland tributary (2.51±0.40 x105 atoms/g; 15.2 m/My) and two smaller upstream tributaries (20.5 m/My and 21.4 m/My). Escarpment streams have less in situ 10Be in their sediment (mean = 1.64±0.55 x 105 atoms/g, n=8) and higher basin area-weighted erosion rates (37.2 m/My). Based on the in situ measurements, the uplands are eroding at approximately half the rate of the escarpment basins. The beach sand has an in situ 10Be concentration (2.75±0.19 x 105 atoms/g) similar to the upland sediment suggesting that the source of beach sand is the larger but more slowly eroding Tablelands. In contrast, the meteoric 10Be concentrations of Barron River sand-sized sediment collected above the escarpment is ~4 fold lower (2.55x107 atoms/g) than the average meteoric 10Be concentration of the 8 escarpment samples (9.94±4.49 x107 atoms/g). This discrepancy cannot be explained by differences in annual average precipitation which ranges only from 1.9 to 2.3 m/yr but likely results from the deep mobility of meteoric 10Be in oxic Tableland soils. Considering meteoric 10Be as a

    The Barron and Johnstone Rivers rise in the basaltic Atherton Tableland, North Queensland, Australia, and flow into the Coral Sea and Great Barrier Reef World Heritage Area (GBRWHA). Natural rainforest in this region was cleared for settlement in the early 20th century. Rapid decline in soil fertility during the 1940's and 50's forced landholders to turn to pasture based industries from row crop agriculture. Since then, these pasture based industries have intensified. The intensified land use has been linked to increases in sediment and nutrient levels in terrestrial runoff and identified as a major environmental threat to the GBRWHA, which has raised alarm for the tourist industry and resource managers. Studies linking land-use to pollutant discharge are often based on measurements and modelling of end of catchment measurements of water quality. Whilst such measurements can be a reasonable indicator of the effects of land use on pollutant discharge to waterways, they are often a gross assessment. This project used rainfall simulations to investigate the relationship between land use and management with sources and sinks of runoff and soil erosion within the Barron and Johnstone Rivers catchments. Rainfall simulations were conducted and pollutant loads measured in natural rainforest, as well as dairy and beef farming systems. The dairy farming systems included an effluent fed pasture, a high mineral fertilizer and supplementary irrigation farm, and a rainfed organic pasture that relied on tropical legumes and introduced grasses and returned organic material to the soil. One of the beef farming systems used a 7-10 day rotation with a low fertilizer regime (kikuyu mostly), while the other, used a long period- two paddock-rotation with no fertiliser and paspalum pastures. The rainforests were generally small isolated enclaves with a well developed shrub layer (1-3 m), and a presence of scattered, deciduous trees. Simulations were carried out on sites which were

    The microbial mediated production of nitrous oxide (N2O) and its reduction to dinitrogen (N2) via denitrification represents a loss of nitrogen (N) from fertilised agro ecosystems to the atmosphere. Although denitrification remains a major uncertainty in estimating N losses from soils, the magnitude of N2 losses and related N2:N2O ratios from soils are largely unknown due to difficulties measuring N2 against a high atmospheric background. In order to address this lack of data, this study investigated the influence of different soil moisture contents on N2 and N2O emissions from a sub-tropical pasture in Queensland/Australia using the 15N gas flux method. Intact soil cores were incubated over 14 days at 80% and 100% water filled pore space (WFPS). Gas samples were taken up to six times per day after application of 15N labelled nitrate, equivalent to 50 kg N ha-1 and analysed for N2 and N2O by isotope ratio mass spectrometry. Fluxes were calculated assuming non-random 15N distribution in the headspace according to Mulvaney and Kurtz (1984) using the labelled pool of nitrate estimated from N2O measurements (Stevens and Laughlin 2001). The main product of denitrification in both treatments was N2. N2 emissions exceeded N2O emissions by a factor of 1.3 ± 0.3 at 80% WFPS and a factor of 3 ± 0.8 at 100% WFPS. The total amount of N-N2 lost over the incubation period was 13.5±1.0 kg N ha-1 at 80% WFPS and 21.8±1.8 kg ha-1 at 100% WFPS respectively. Over the entire incubation period, N2 emissions remained elevated at 100% WFPS, showing high variation between soil cores, while related N2O emissions decreased. At 80% WFPS, N2 emissions increased constantly over time showing significantly higher values after day five. At the same time, N2O fluxes declined. Consequently, N2:N2O ratios rose over the incubation period in both treatments. Overall denitrification rates and related N2:N2O ratios were higher at 100% WFPS compared to 80% WFPS, confirming WFPS as a major driver of

    Traditionally, soil movement has been reported in the literature under processes of raindrop impact/splash, overland sheet flow, rills, gullies, and ephemeral and fluent streams and rivers. From the perspective of a land manager this information needs to be structured in a way that integrates these many strands of knowledge thus facilitating decision making about land use operations and conservation of the resource. This paper describes the interconnectedness of hydrologic and sedimentological processes of landscape elements and segments in the headwaters of the semi/arid - subhumid Fitzroy River, Central Queensland, Australia and options for managing severe erosion. The central notion of the hypothesis is that sediment has been pulsing through this landscape for thousands of years. Stratigraphy of valley alluvial fans indicates that the valleys have been filled and re-excavated many times. The pulsing of sediment through valleys where incision of alluvial fans and subsequent downstream deposition creates a sequence of similar landforms, but of a different scale, is largely driven by the morphology of the landforms themselves. The "noses" of alluvial fans exhibit a convex shape with the surface being characterised by finer sediments. Positive pore water pressures develop throughout the fan due to the highest infiltration occurring at the head of the fan where coarsest sediments are deposited. Strata of coarser materials are thus laid down progressively up-valley as the fans continue to grow. In the base of the "nose" of alluvial fans there are the remnants of the coarse material that were laid down initially and movement of water through fans is subsequently along the layers of coarse gravel and exfiltrated at the "nose" of the fan. A "pothole" in these locations is the first visible evidence of the impending rapid retreat of a new gully whereby sediment is pulsed down-valley and again deposited to form a new fan. Thus alluvial fans are destroyed and gullies are in

    Only photographic prints and negative films of day-visible, day-IR and night-IR imagery were received. For northwest Queensland, only five day-visible and day-IR frames of acceptable quality were received. A master-grid was established over these frames within which selected grid sections are being enlarged photographically for the identification of stream courses and geological features permitting an interpretation of the imagery relative to ground truth information. The imagery is also being scanned and digitized using a Joyce-Loebl microdensitometer for classification purposes. For areas for which good quality HCMM imagery is available, valuable information is obtained on ephemeral and seasonal drainage systems. The day-IR cover is particularly helpful.

    In the present study, we review the known zoogonid cercariae, summarise their life-cycles and first intermediate host distributions, and present a new cercaria, Cercaria capricornia XI (Digenea: Zoogonidae), which was found in one of three nassariid gastropods, Nassarius olivaceus (Bruguière), surveyed in the intertidal zone in the Capricornia region of Central Queensland, Australia. Morphological data and molecular analysis of the ITS2 rDNA region support placement of this cercaria in the family Zoogonidae but do not allow any further resolution of its identity. There are now fifteen cercariae described as belonging to the Zoogonidae; thirteen of these, including the present species, infect neogastropods as first intermediate hosts and two use vetigastropods. This study reinforces the pattern that the Nassariidae is by far the most commonly reported family for the Zoogonidae. Given its richness we predict that the Nassariidae will prove to harbour many more zoogonid species.

    Background Canine flea-allergy dermatitis (FAD), a hypersensitivity response to antigenic material in the saliva of feeding fleas, occurs worldwide and remains a common presentation in companion animal veterinary practice despite widespread availability of effective systemic and topical flea-control products. Hypothesis/Objectives To evaluate the clinical response in dogs with FAD treated topically with indoxacarb, a novel oxadiazine insecticide. Animals Twenty-five client-owned dogs in Queensland, Australia diagnosed with pre-existing FAD on the basis of clinical signs, flea-antigen intradermal and serological tests. Methods An open-label, noncontrolled study, in which all dogs were treated with topical indoxacarb at 4 week intervals, three times over 12 weeks. Results Twenty-four dogs completed the study. Complete resolution of clinical signs of FAD was observed in 21 cases (87.5%), with nearly complete resolution or marked improvement in the remaining three cases. Mean clinical scores (Canine Atopic Dermatitis Extent and Severity Index-03) were reduced by 93.3% at week 12. Mean owner-assessed pruritus scores were reduced by 88% by week 12. Mean flea counts reduced by 98.7 and 100% in weeks 8 and 12, respectively. Conclusions and clinical importance Topical indoxacarb treatment applied every 4 weeks for 12 weeks, without concomitant antipruritic or ectoparasiticide therapy, completely alleviated flea infestations in all dogs and associated clinical signs of FAD in a high proportion of this population of dogs in a challenging flea-infestation environment.

    A total of 11 rainfall simulations were conducted on four different plots (ranging in area from 22.10 to 26.20 m2) in a sugarcane field (with slopes varying from 1-9% and a groundcover variability of bare - 100% cover) in the Mackay region of Northern Queensland. The objectives of these rainfall simulation experiments were many, but this paper discusses the measurement methodology and data quality of rainfall generated and subsequent runoff. Rainfall amount during the simulations was measured using two different sizes of rain gauges placed at different locations on the plot (left, centre, and right sides of the experimental plot). In addition to the 203mm ordinary rain gauges, three pluviometers (300mm) were placed along the centre of the plot to measure rainfall as a function of time during the simulation. The rainfall data from these three pluviometers was collected using dataloggers and processed using a computer program called Datalog, which converted the number of tips/minute into mm/h. Due to spatial variation of rainfall intensity applied to the surface as a function of height from the nozzles of the rainfall simulators, correction factors were determined using a computer program called ERFS developed for this purpose. The rainfall from each gauge and pluviometer was subsequently corrected for distance from the nozzles of the simulator and height of the gauge by multiplying it by the corresponding correction factor. The spatial distribution of rainfall amount during each simulation was determined by spatially interpolating measured amounts in order to ascertain the best estimate of applied rainfall and its energy. Runoff data during each simulation was collected using tipping buckets connected to data loggers. Runoff amounts were also manually collected at specified intervals as a back up, and for validation of those collected using tipping buckets in determining runoff rates for each simulation. Soil cores were taken for determining soil moisture balances

    Full Text Available Background Bull riding is an increasingly popular and growing professional sport in Australia. This is the first national study that investigates bull riding-related injuries. Method A six-year retrospective study of patients admitted to Rockhampton Base Hospital with acute injuries sustained whilst bull riding. Patients were identified from the Rockhampton Hospital international coding system and surgical audit excel databases. Supporting information was found from patient chart review. Results Thirty-eight patients were admitted during the study. Injuries increased from 2008. The most common injuries were to limbs (52%, chest (15% and brain (10%. Life-threatening injuries were all caused by a direct kick or trampling by the bull; 5% of patients needed air transfer to Brisbane, and 10% to Rockhampton for their acute care. The only complication was infection of open wounds. The average hospital stay was 2.2 (range= 1-5, SD= 1.1 days and 64% of patients required operative intervention. Conclusion Patients that had been kicked or trampled should be identified as having potentially life-threatening injuries, and transferred for review at an appropriate facility. Due to the high risk of infection all contaminated wounds should be washed out formally and receive antibiotics. Protective equipment should be encouraged among riders.

    Consent by patients to voluntary sterilization frees surgeons from criminal responsibility for assault when such consent is given freely with the knowledge of the purpose and consequence of the procedure, and when the operation is performed with professional skill. However, it is considered unethical for surgeons to sterilize a married man or woman of child-bearing age unless they have satisfied themselves that the other party to the marriage has consented to the procedure.

    2015-10-01

    Statistics of radar-retrievals of precipitation are presented. A K-means clustering algorithm is applied to an historical record of radiosonde measurements which identified three major synoptic regimes; a dry, stable regime with mainly westerly winds prevalent during winter, a moist south easterly trade wind regime and a moist northerly regime both prevalent during summer. These are referred to as westerly, trade wind and northerly regimes, respectively. Cell statistics are calculated using an objective cell identification and tracking methodology on data obtained from a nearby S-band radar. Cell statistics are investigated for the entire radar observational period and also during sub-periods corresponding to the three major synoptic regimes. The statistics investigated are cell initiation location, area, rainrate, volume, height, height of the maximum reflectivity, volume greater than 40 dBZ and storm speed and direction. Cells are found predominantly along the elevated topography. The cell statistics reveal that storms which form in the dry, stable westerly regime are of comparable size to the deep cells which form in the northerly regime, larger than those in the trade regime and, furthermore, have the largest rainrate. However, they occur less frequently and have shorter lifetimes than cells in the other regimes. Diurnal statistics of precipitation area and rainrate exhibit early morning and mid afternoon peaks, although the areal coverage lags the rainrate by several hours indicative of a transition from convective to stratiform precipitation. The probability distributions of cell area, rainrate, volume, height and height of the maximum re ectivity are found to follow lognormal distributions.

  2. Fish Distribution in Far Western Queensland, Australia: The Importance of Habitat, Connectivity and Natural Flows

    Directory of Open Access Journals (Sweden)

    Adam Kerezsy

    2014-06-01

    Full Text Available The endorheic Lake Eyre Basin drains 1.2 million square kilometres of arid central Australia, yet provides habitat for only 30 species of freshwater fish due to the scarcity of water and extreme climate. The majority are hardy riverine species that are adapted to the unpredictable flow regimes, and capable of massive population booms following heavy rainfall and the restoration of connectivity between isolated waterholes. The remainder are endemic specialists from isolated springs with very restricted ranges, and many are listed under relevant state and national endangered species legislation and also by the International Union for Conservation of Nature (IUCN. For these spring communities, which are sustained by water from the Great Artesian Basin, survival is contingent on suitable habitat persisting alongside extractive mining, agriculture and the imposition of alien species. For the riverine species, which frequently undertake long migrations into ephemeral systems, preservation of the natural flow regime is paramount, as this reinstates riverine connectivity. In this study, fish were sampled from the Bulloo River in the east to the Mulligan River in the west, along a temporal timeframe and using a standard set of sampling gears. Fish presence was influenced by factors such as natural catchment divides, sampling time, ephemerality and the occurrence of connection flows and flooding. Despite the comparatively low diversity of species, the aquatic systems of this isolated region remain in good ecological condition, and as such they offer excellent opportunities to investigate the ecology of arid water systems. However, the presence of both endangered species (in the springs and invasive and translocated species more widely indicates that active protection and management of this unique area is essential to maintain biodiversity and ecosystem integrity.

    Ostwald, J.

    1992-09-01

    The Mary Valley manganese deposits exhibit mineralogy and textures characteristic of at least four parageneses. The deposits consist mainly of isolated occurrences of braunite, together with a number of lower and higher valency manganese oxides, and manganese silicates, in bedded radiolarian cherts and jaspers of Permian age. The parageneses are: (a) Braunite — quartz (primary), (b) Braunite — hausmannite — spessartine — tephroite — quartz (metamorphic). (c) Hydrated manganese silicates — barite — braunite — hausmannite (hydrothermal veins), (d) Tetravalent manganese oxides (pyrolusite, cryptomelane, manjiroite, nsutite) (supergene). The primary mineralisation is interpreted as the result of the geochemical separation of Mn from Fe in a submarine exhalative system, and the precipitation of Mn as oxide within bedded radiolarian oozes and submarine lavas. During diagenesis this hydrothermal manganese oxide reacted with silica to produce primary braunite. The later geological of evolution of this volcanogenicsedimentary deposit involved metamorphism, hydrothermal veining by remobilised manganese, and supergene enrichment.

    Full Text Available Computer systems have become commonplace in most SMEs and technology is increasingly becoming a part of doing business. In recent years, the Internet has become readily available to businesses; consequently there has been growing pressure on SMEs to take up e-commerce. However, e-commerce is perceived by many as being unproven in terms of business benefit. This research aims to determine what, if any, benefits are derived from assimilating e-commerce technologies into SME business processes. This paper presents three in-depth case studies from the Real Estate industry in a regional setting. Overall, findings were positive and identified the following experiences: enhanced business efficiencies, cost benefits, improved customer interactions and increased business return on investment.

    Full Text Available Trials in the Condamine-Balonne basin, Australia, compared 11 promising perennial pasture grass accessions (4 Bothriochloa, 2 Cenchrus, 2 Urochloa and 1 each of Digitaria, Eragrostis and Panicum species against the best similar commercial cultivars on the basis of ease of establishment from seed, persistence once established, forage yield and ease of seed production.  Accessions sown at a site were determined by prior experience with them on a range of soils.  High quality seed was relatively easy to produce for both Urochloa species and for Eragrostis curvula CPI 30374 but problematic for the Bothriochloa spp.  Once established, all accessions persisted for 3–5 years and most were well grazed, but adequate establishment was sometimes a problem with Panicum stapfianum and Bothriochloa ewartiana.  The dry matter yield ratings of the non-commercial lines were similar to those of the commercial equivalents of the same species.  While agronomically valuable, none of the promising new grasses was considered worthy of commercialization at this point because their strengths did not warrant the setting up of a seed-production business in competition with current commercial enterprises.  Long-standing cultivars such as Gayndah buffel and Nixon sabi grass continued to exhibit their superior pasture qualities.Keywords: Herbicide tolerance, persistence, forage yield, establishment ease, commercialization, seed production.DOI: 10.17138/TGFT(315-26

  10. Geology and genesis of uranium-rare earth deposits at Mary Kathleen, Northwest Queensland

    Energy Technology Data Exchange (ETDEWEB)

    Scott, A.K.; Scott, A.G.

    1985-02-01

    The Mary Kathleen uranium deposit occurs in 1740-1780 M yr-old calc-silicate metasedimentary and meta-igneous rocks of the Corella Formation which have been tightly folded into the Mary Kathleen Syncline. The Corella Formation consists of mafic and felsic tuffaceous calc-silicates, quartzite, and minor marble, conglomerate and basic volcanics. Uranium-rare earth mineralisation is closely associated with certain mafic rocks and occurs within or close to garnet-rich masses. At Mary Kathleen, uraninite grains are enclosed mainly by allanite which is distributed through massive garnet as an irregular honeycomb of interconnected shoots and lenses. The mineralisation occurs along strike from dioritic rocks and conglomerate and lies close to the axis of the Mary Kathleen Syncline and adjacent to a major fault zone. At other localities allanite-uraninite mineralisation is broadly stratiform. The mineralisation is interpreted to occur at or near centres of basic volcanism. Garnet formation and uranium-rare earth concentrations are believed to be caused by the volcanism, and to be contemporaneous with it. The former is seen as alteration of a hot, saturated pile of volcano-sedimentary material and the latter as intermittent hydrothermal exhalations. Deposition, volcanism, garnet formation, uranium and rare-earth mineralisation, granite and gabbro formation, and tectonism are seen as a continuum of interrelated processes which operated throughout the period of formation of the rocks in the Mary Kathleen Syncline.

    Rural settings challenge health care providers to provide optimal medication services in a manner that is timely and of high quality. Extending the roles of rural health care providers is often necessary to improve access to medication services; however, there appears to be a lack of pharmacy-based involvement and support within the medication system. This article explores medication supply and management issues in rural settings, based on the governance perspectives of key informants on regulatory aspects, policy, and professional practice. The specific objectives were to (1) identify the key issues and existing facilitators and (2) explore the potential roles of pharmacy to improve medication supply and management services. Semi-structured interviews were conducted with representatives within regulatory or professional organizations. The participants were key informants who held leadership and/or managerial roles within their respective organizations and were recruited to provide insights from a governance perspective before data collection in the community. An interview guide, informed by the literature, assisted the flow of interviews, exploring topics, such as key issues, existing initiatives, and potential pharmacy-based facilitators, in relation to medication supply and management in rural settings. Issues identified that hindered the provision of optimal medication supply and management services in the rural areas centered on workforce, interprofessional communication, role structures, and funding opportunities. Legislative and electronic developments and support mechanisms aim to facilitate medication processes in rural areas. Potential initiatives to further enhance medication services and processes could explore extended roles for pharmacists and pharmacy support staff, as well as alternative service delivery models to enhance pharmacy workforce capacity. The study provided an overview of key issues with medication supply and management and highlighted the potential for increased pharmacy involvement to improve and support medication services in rural areas. The governance views of these key informants could be used to inform policy and practice related to rural medication services. Copyright © 2012 Elsevier Inc. All rights reserved.

    Three Australian tephritid fruit flies (Bactrocera tryoni – Q-fly,Bactrocera neohumeralis – NEO, andBactrocera jarvisi – JAR) are promising models for genetic studies of pest status and invasiveness. The long history of ecological and physi-ological studies of the three species has been augmented by the development of a range of genetic and genomic tools, including the capacity for forced multigeneration crosses between the three species followed by selection experiments, a draft genome for Q-fly, and tissue- and stage-specific transcriptomes. The Q-fly and NEO species pair is of particular interest. The distribution of NEO is contained entirely within the wider distribution of Q-fly and the two species are ecologically extremely similar, with no known differences in pheromones, temperature tolerance, or host-fruit utilisation. However there are three clear differences be-tween them: humeral callus colour, complete pre-mating isolation based on mating time-of-day, and invasiveness. NEO is much less invasive, whereas in historical times Q-fly has invaded southeastern Australia and areas of Western Australia and the North-ern Territory. In southeastern fruit-growing regions, microsatellites suggest that some of these outbreaks might derive from ge-netically differentiated populations overwintering in or near the invaded area. Q-fly and NEO show very limited genome diffe-rentiation, so comparative genomic analyses and QTL mapping should be able to identify the regions of the genome controlling mating time and invasiveness, to assess the genetic bases for the invasive strains of Q-fly, and to facilitate a variety of improve-ments to current sterile insect control strategies for that species [Current Zoology 61 (3): 477–487, 2015].

    Late-onset sepsis (LOS) in neonates contributes significantly to both morbidity and mortality. To determine the incidence of LOS, risk factors for disease and the impact on subsequent hospital course, we evaluated a cohort of 6340 neonates admitted to the neonatal intensive care unit and of neonates (3-28 days) admitted from the community between January 2005 and January 2016. This was a retrospective case review of all neonates admitted with suspected LOS who had positive blood culture and/or cerebrospinal fluid cultures, for an organism determined to be a pathogen. Of 6340 neonates who survived beyond 3 days, 2271 (35.8%) had 1 or more blood cultures collected for suspected LOS. Of these, 146 (6.4%) positive blood cultures were thought to represent true bacteremia. The vast majority of infections (73%) were caused by Gram-positive organisms, with coagulase-negative staphylococci accounting for 39.8% of infections. Late-onset neonatal sepsis occurred predominantly in the 24-28-week age group (75.9%) and in neonates who weighed less than 1000 g (73.6%). The incubation time for positive blood cultures for Gram-negative sepsis was less (13 hours) when compared with Gram-positive sepsis (20 hours). Thrombocytopenia, elevated C-reactive protein and chorioamnionitis were consistently associated with late-onset Gram-negative sepsis (P < 0.05). Eight neonates (6%) died secondary to LOS. LOS contributes significantly to mortality and morbidity in neonates and remains a challenge to clinicians. Necessary steps to reduce late-onset neonatal sepsis should be undertaken.

  18. Incubation temperature, morphology and performance in loggerhead (Caretta caretta turtle hatchlings from Mon Repos, Queensland, Australia

    2015-07-01

    Full Text Available Marine turtles are vulnerable to climate change because their life history and reproduction are tied to environmental temperatures. The egg incubation stage is arguably the most vulnerable stage, because marine turtle eggs require a narrow range of temperatures for successful incubation. Additionally, incubation temperature affects sex, emergence success, morphology and locomotor performance of hatchlings. Hatchlings often experience high rates of predation in the first few hours of their life, and increased size or locomotor ability may improve their chances of survival. Between 2010 and 2013 we monitored the temperature of loggerhead (Caretta caretta; Linnaeus 1758 turtle nests at Mon Repos Rookery, and used these data to calculate a mean three day maximum temperature (T3dm for each nest. We calculated the hatching and emergence success for each nest, then measured the mass, size and locomotor performance of hatchlings that emerged from those nests. Nests with a T3dm greater than 34°C experienced a lower emergence success and produced smaller hatchlings than nests with a T3dm lower than 34°C. Hatchlings from nests with a T3dm below 34°C performed better in crawling and swimming trials than hatchlings from nests with a T3dm above 34°C. Thus even non-lethal increases in global temperatures have the potential to detrimentally affect fitness and survival of marine turtle hatchlings.

    Dialkyl phthalate esters (phthalates) are ubiquitous chemicals used extensively as plasticizers, solvents and adhesives in a range of industrial and consumer products. 1,2-Cyclohexane dicarboxylic acid, diisononyl ester (DINCH) is a phthalate alternative introduced due to a more favourable toxicological profile, but exposure is largely uncharacterised. The aim of this study was to provide the first assessment of exposure to phthalates and DINCH in the general Australian population. De-identified urine specimens stratified by age and sex were obtained from a community-based pathology laboratory and pooled (n=24 pools of 100). Concentrations of free and total species were measured using online solid phase extraction isotope dilution high performance liquid chromatography tandem mass spectrometry. Concentrations ranged from 2.4 to 71.9ng/mL for metabolites of di(2-ethylhexyl)phthalate, and from phthalate metabolites concentrations in Australia were at least two times higher than in the United States and Germany; and may be related to legislative differences among countries. DINCH metabolite concentrations were comparatively low and consistent with the limited data available. Ongoing biomonitoring among the general Australian population may help assess temporal trends in exposure and assess the effectiveness of actions aimed at reducing exposures.

    Dental caries is a multifactorial condition, prevention of which requires comprehensive understanding of both contextual and compositional determinants and their population impact. To investigate contextual and compositional factors associated with the prevalence of dental caries in children and to estimate the population impact of those factors. Children in one Australian state were selected through stratified random sampling selection in 2010-2011. Oral epidemiological examinations provided individual-level outcomes: prevalence of dental caries in the primary (among 5- to 8-year-olds) and permanent dentitions (9- to 14-year-olds). Socioeconomic status, oral health behaviours and practices and dietary patterns were explanatory factors at the individual-level, school-level and area-level fluoridation status. Three-level multilevel multivariable models were sequentially specified for the prevalence of dental caries to estimate prevalence ratios (PR) associated with explanatory factors, adjusting for covariates and between- and within-group variances. Population attributable fraction (PAF) was estimated as the population impact of the statistically significant explanatory factors. Data from 2214 5- to 8-year-olds and 3186 9- to 14-year-olds from 207 schools in 16 areas were analysed. The prevalence of dental caries in the primary and the permanent dentitions was 47.1% (43.9-50.4) and 38.8% (36.1-41.6), respectively. The highest prevalence of dental caries was observed in the nonfluoridated areas. In bivariate associations, factors at three levels were associated with prevalence of dental caries. In the full models, children in the nonfluoridated areas had significantly higher prevalence of dental caries [PR for the primary: 1.29 (1.11-1.50); PR for the permanent 1.49 (1.01-2.21)] compared with children in fluoridated areas, controlling for other factors. PAF estimates indicated that lack of water fluoridation attributed to 21% and 31% of primary and permanent dental caries, respectively in this child population. A multitude of factors had significant population impact on the prevalence of dental caries in children. Water fluoridation has a significant population impact on dental caries experience in this child population. © 2015 John Wiley & Sons A/S. Published by John Wiley & Sons Ltd.

  4. Dietary specialization and Eucalyptus species preferences in Queensland koalas (Phascolarctos cinereus).

    2011-01-01

    Koalas specialize on Eucalyptus leaves, but also feed selectively. Food choice is not random, but depends on various factors that are not well understood, although most research has focused on the role of secondary plant compounds. We studied the feeding choices of four adult male koalas housed at the San Diego Zoo. All subjects had a choice of nine types of Eucalyptus leaves over the eight-week study. The most preferred species was E. camuldulensis, but individual males exhibited different feeding preferences. We conclude that food selectivity among koalas is probably due to multiple factors, rather than only a consequence of secondary plant chemicals. A combination of intrinsic factors, such as developmental trajectory and reproductive state, as well as extrinsic factors, such as leaf chemical fingerprint and moisture, probably interact to shape koala foraging preferences. Koalas forage almost exclusively on Eucalyptus species, but have evolved an adaptive flexibility, enabling them to exploit various Eucalyptus species. © 2010 Wiley-Liss, Inc.

    The study assessed the prevalence of obesity and related conditions among Sudanese adult migrants living in Brisbane, Australia. Data were obtained on 314 Sudanese immigrants aged 18-70 years. Measured body mass index (BMI) and self-reported diabetes and hypertension were obtained. More than half (51%) of participants were overweight or obese, 6.4% reported having type 2 diabetes while 12.4% had hypertension. The full adjusted regression model explained 28.1% of the variance in BMI. Odds of reporting type 2 diabetes increased with age, BMI and were greater among participants rating health as poor/fair than those rating as good/very good/excellent. Odds of high blood pressure increased with age, BMI, and were higher among participants rating health as poor/fair than those as good/very good/excellent. Health promotion programs to prevent weight gain in this subpopulation will significantly reduce inequalities related to type 2 diabetes and improve cardio-vascular outcomes.

  6. Paleomagnetism of the Newcastle Range, northern Queensland: Eastern Gondwana in the Late Paleozoic

    The Newcastle Range is an extensive (2500 km2) and well-exposed caldera system erupted on the trailing edge of Eastern Gondwana between 325 and 295 Ma. Paleomagnetic samples were collected from ignimbrites and associated microgranitoid intrusions from the central, northern and southern calderas from which three components of magnetization are recognized. Component 1 is considered to be a viscous magnetization acquired during the Brunhes Chron. A presumed Permian component, C2, is found in seven paleomagnetic sites with a mean pole at 30.9°S, 139.7°E (K = 13.9, A95 = 16.8°, ASD = 21.7°), agreeing with previously reported Permian data from Australia. Carboniferous units have a well-defined characteristic component, C3, distinguished by dual polarity (predominantly reversed) and moderate to steep inclination directions. Paleomagnetic polarities in the Newcastle Range Volcanics are formation dependent and new constraints on the timing of Carboniferous volcanism (˜325-317 Ma) are consistent with recent reanalysis of the base of the Permo-Carboniferous Reversed Superchron (PCRS). A mean paleomagnetic pole, calculated from 15 VGPs, lies at 63.4°S, 125°E (K = 26.22, A95 = 7.6°, ASD = 15.8°), suggesting that Australia remained at midlatitudes into the Middle Carboniferous. This paleomagnetic pole is consistent with similarly aged poles from Western Gondwana, the conformity of which indicates contributions from nondipole components of the Earth's paleofield were probably not significant in the time immediately preceding the PCRS.

  8. Palaeomagnetism of the Early Permian Mount Leyshon Intrusive Complex and Tuckers Igneous Complex, North Queensland, Australia

    Clark, D. A.; Lackie, M. A.

    2003-06-01

    This study provides reliable, precisely defined and well-dated Early Permian (286 +/- 6 Ma) palaeomagnetic poles for Australia from the Mount Leyshon Intrusive Complex (MLIC) and the Tuckers Igneous Complex (TIC). Both complexes are associated with prominent negative magnetic anomalies, indicating the presence of rocks carrying stable remanence of reverse polarity, with a Koenigsberger ratio greater than unity. The characteristic remanence carried by the intrusive phases and by locally remagnetized, contact-metamorphosed host rocks is always of reverse polarity, consistent with acquisition during the Permo-Carboniferous (Kiaman) Reverse Superchron. The corresponding palaeopoles confirm that Australia occupied high latitudes in the Early Permian. The pole positions are: MLIC: lat. = 43.2 °S, long. = 137.3 °E dp = 6.0°, dm = 6.4° Q= 6; TIC: lat. = 47.5 °S, long. = 143.0 °E, dp = 6.0°, dm = 6.6° Q= 6. Permian palaeomagnetic overprinting is detectable at considerable distances from the MLIC (2-3 km), well beyond the zone of visible alteration. The primary nature of the Early Permian palaeomagnetic signature is established by full baked contact/aureole tests at both localities. Other new data from Australia are consistent with the poles reported here. Comparison of the Australian, African and South American Apparent Polar Wander Paths (APWP) suggests that mean Permian and Triassic poles from West Gondwana, particularly from South America, are biased by remagnetization in the Jurassic-Cretaceous and that the Late Palaeozoic-Mesozoic APWP for Gondwana is best defined by Australian data. The Australian APWP exhibits substantial movement through the Mesozoic. Provided only that the time-averaged palaeofield was zonal, the Early Triassic palaeomagnetic data from Australia provide an important palaeogeographic constraint that the south geographic pole was within, or very close to, SE Australia around 240 Ma. The new Early Permian poles are apparently more consistent with Pangaea B-type reconstructions of Gondwana and Laurussia than with the Pangaea A2 configuration. This may be partly an artefact of reconstruction problems within Gondwana, as systematic differences between approximately coeval, apparently reliable, Permo-Carboniferous poles from Africa, South America and Australia are evident in standard Gondwana reconstructions. These discordances require a tighter fit of the southern continents, suggesting that some attenuation of continental margins, not accounted for in the reconstructions, has occurred during breakup of Gondwana, or that the fit between East and West Gondwana needs to be substantially modified. If stretching of continental margins during breakup of supercontinents is a general phenomenon, it may help to ameliorate, but not solve, the long-standing controversy regarding Pangaea reconstructions. Although alternative Pangaea reconstructions, such as Pangaea B, may reconcile poles from Laurussia with Australian poles in the Late Carboniferous-Early Permian, no plausible reconstruction can bring the Early Triassic poles into agreement. This suggests that persistent departures from a pure dipole field may have been present in the Early Triassic. Lesser, but still significant, non-dipole effects may also have been present during the Late Carboniferous and Permian, and may help resolve the Pangaea A versus B controversy, without requiring substantial attenuation of continental margins or intracontinental deformation. We suggest that the most parsimonious interpretation of the palaeomagnetic and geological information is that Laurussia and Gondwana remained in a Pangaea A2-type configuration through the Permian and Triassic. Discordance between the APWPs for these two supercontinents is attributable mainly to persistent non-dipole components of the geomagnetic field, which were most important in the Early Triassic.

    Full Text Available BACKGROUND: Australia's dinosaurian fossil record is exceptionally poor compared to that of other similar-sized continents. Most taxa are known from fragmentary isolated remains with uncertain taxonomic and phylogenetic placement. A better understanding of the Australian dinosaurian record is crucial to understanding the global palaeobiogeography of dinosaurian groups, including groups previously considered to have had Gondwanan origins, such as the titanosaurs and carcharodontosaurids. METHODOLOGY/PRINCIPAL FINDINGS: We describe three new dinosaurs from the late Early Cretaceous (latest Albian Winton Formation of eastern Australia, including; Wintonotitan wattsi gen. et sp. nov., a basal titanosauriform; Diamantinasaurus matildae gen. et sp. nov., a derived lithostrotian titanosaur; and Australovenator wintonensis gen. et sp. nov., an allosauroid. We compare an isolated astragalus from the Early Cretaceous of southern Australia; formerly identified as Allosaurus sp., and conclude that it most-likely represents Australovenator sp. CONCLUSION/SIGNIFICANCE: The occurrence of Australovenator from the Aptian to latest Albian confirms the presence in Australia of allosauroids basal to the Carcharodontosauridae. These new taxa, along with the fragmentary remains of other taxa, indicate a diverse Early Cretaceous sauropod and theropod fauna in Australia, including plesiomorphic forms (e.g. Wintonotitan and Australovenator and more derived forms (e.g. Diamantinasaurus.

    1997-07-01

    This paper outlines a successful approach that was followed to evaluate grass and legume accessions for revegetation of low fertility and saline coal mine spoils. At the first stage, using seed collection records (passport data) of the Australian Tropical Forages Genetic Resource Centre, a range of grasses and legumes adapted to low rainfall, clay soils and saline areas were selected. At the second stage, legume seed was germinated in NaCl solutions of 0 to 0.2 M and salinity tolerance was assessed based on germination percentage and seedling vigour. At the third stage, germination of legumes was assessed in pots filled with mine top-soil and spoils to be revegetated. Grasses were not included in stages 2 and 3 as adequate passport data was available to select a range of accession for the 4th stage. The fourth stage of evaluation comprised field trails of 10 grass and 10 legume accessions, on two top-soils and two spoils. A stoloniferous from of Urochloa mosamblicensis was the most promising grass providing up to 20% of ground cover 12 months after establishment. Legumes surviving at the end of the first season were Desmanthus subulatus, D. virgatus and Neptunia dimorphantha on top-soil and Clitoria ternatea, Leucaena leucocephala, and Rhynchosia sublobata on the spoil. Depending on long term survival, grass and legume accessions will be released as cultivars for minesite revegetation purposes. 14 refs., 4 figs., 3 tabs.

    1990-06-01

    Five shallow areas (sea grass, river mouth, mangrove fringe and sewage outlet. A total of 86 fish species were recorded. Five species (6%) were regarded as true marine fish but these were of rare occurrence (0·5%). Four species (5%) were highly abundant (51%) and 57 species (66%) were represented by low numbers of fish (5%). The sewage outlet and the river mouth sites were found to contain the highest number of fish with relatively low numbers of species. The sand-drifting and the sea grass sites were different in fish fauna, and both were different from the remaining three sites which were of high similarity in fish faunal groups. Food availability, preference for habitats, sea grass vegetation, juvenile/adult segregation, season of juvenile recruitment and hydrological characteristics were thought to be important factors affecting the distribution of these species of fish.

    Metofluthrin is highly effective at reducing biting activity in Aedes aegypti. Its efficacy lies in the rapid onset of confusion, knockdown, and subsequent kill of a mosquito. In the field, there are a variety of scenarios that might result in sublethal exposure to metofluthrin, including mosquitoes that are active at the margins of the chemical's lethal range, brief exposure as mosquitoes fly in and out of treated spaces or decreasing efficacy of the emanators with time. Sublethal effects are key elements of insecticide exposure and selection. The metofluthrin dose for each treatment group of male and female Ae. aegypti was controlled using exposure time intervals to a 10% active ingredient (AI) metofluthrin emanator. Room size and distance from the emanator for all groups was maintained at 3 m. In bioassay cages, male Ae. aegypti were exposed at 0, 5, 10, 20, 30 and 40-min intervals. Females were exposed in bioassay cages at 0, 10, 20, 30, 40 and 60-min intervals. Mortality rates and fecundity were observed between the exposure time groups for both sexes. Female Ae. aegypti exposed for 60 min had a significantly higher mortality rate (50%), after a 24-h recovery period, than other exposure times, 10, 20, 30 and 40 min (P metofluthrin exposure were as likely to produce viable eggs with an unexposed female as males that had not been exposed (P > 0.05). Regardless of sex, if a mosquito survived exposure, it would be as biologically successful as its unexposed counterpart. Portability of the metofluthrin emanator and delayed knockdown effects create opportunities for sublethal exposure and potential pyrethroid resistance development in Ae. aegypti, and should be taken into consideration in recommendations for field application of this product, including minimum exposure periods and a prescribed number of emanators per room based on volume.

  19. Impacts of prescribed burning on soil greenhouse gas fluxes in a suburban native forest of south-eastern Queensland, Australia

    Full Text Available Prescribed burning is a forest management practice that is widely used in Australia to reduce the risk of damaging wildfires. It can affect both carbon (C and nitrogen (N cycling in the forest and thereby influence the soil–atmosphere exchange of major greenhouse gases, i.e. carbon dioxide (CO2, methane (CH4 and nitrous oxide (N2O. To quantify the impact of a prescribed burning (conducted on 27 May 2014 on greenhouse gas exchange and the potential controlling mechanisms, we carried out a series of field measurements before (August 2013 and after (August 2014 and November 2014 the fire. Gas exchange rates were determined at 4 replicate sites which were burned during the combustion and another 4 adjacent unburned sites located in green islands, using a set of static chambers. Surface soil properties including temperature, pH, moisture, soil C and N pools were also determined either by in situ measurement or by analysing surface 10 cm soil samples. All of the chamber measurements indicated a net sink of atmospheric CH4, with mean CH4 uptake ranging from 1.15 to 1.99 mg m−2 day−1. The burning significantly enhanced CH4 uptake as indicated by the significant higher CH4 uptake rates at the burned sites measured in August 2014. While within the next 3 months the CH4 uptake rate was recovered to pre-burning levels. Mean CO2 emission from forest soils ranged from 2721.76 to 7113.49 mg m−2 day−1. The effect of prescribed burning on CO2 emission was limited within the first 3 months, as no significant difference was observed between the burned and the adjacent unburned sites in both August and November 2014. The temporal dynamics of the CO2 emission presented more seasonal variations, rather than burning effects. The N2O emission at the studied sites was quite low, and no significant impact of burning was observed. The changes in understory plants and litter layers, surface soil temperature, C and N substrate availability and microbial activities, resulting from the burning, were the factors that controlled the greenhouse gas exchanges. Our results suggested that the low intensity prescribed burning would decrease soil CO2 emission and increase CH4 uptake, however, this effect would be present within a relative short period. Only slight changes in the surface soil during the combustion and very limited damages in the mineral soils supported the quick recovery of the greenhouse gas exchange rates.

    A recent paper inferred that all seagrass in Cairns Harbour, tropical north-eastern Australia, had undergone ‘complete and catastrophic loss’ as a result of tropical cyclone Yasi in 2011. While we agree with the concern expressed, we would like to correct the suggestion that the declines were the result of a single climatic event and that all seagrass in Cairns Harbour were lost. Recent survey data and trend analysis from an on-ground monitoring program show that seagrasses in Cairns Harbour do remain, albeit at low levels, and the decline in seagrasses occurred over several years with cyclone Yasi having little additional impact. We have conducted annual on-ground surveys of seagrass distribution and the above-ground meadow biomass in Cairns Harbour and Trinity Inlet since 2001. This has shown a declining trend in biomass since a peak in 2004 and in area since it peaked in 2007. In 2012, seagrass area and above-ground biomass were significantly below the long-term (12 year) average but seagrass was still present. Declines were associated with regional impacts on coastal seagrasses from multiple years of above-average rainfall and severe storm and cyclone activity, similar to other nearby seagrass areas, and not as a result of a single event.

    Parabens, benzophenone-3 and triclosan are common ingredients used as preservatives, ultraviolet radiation filters and antimicrobial agents, respectively. Human exposure occurs through consumption of processed food and use of cosmetics and consumer products. The aim of this study was to provide a preliminary characterisation of exposure to selected personal care product chemicals in the general Australian population. De-identified urine specimens stratified by age and sex were obtained from a community-based pathology laboratory and pooled (n=24 pools of 100). Concentrations of free and total (sum of free plus conjugated) species of methyl, ethyl, propyl and butyl paraben, benzophenone-3 and triclosan were quantified using isotope dilution tandem mass spectrometry; with geometric means 232, 33.5, 60.6, 4.32, 61.5 and 87.7ng/mL, respectively. Age was inversely associated with paraben concentration, and females had concentrations approximately two times higher than males. Total paraben and benzophenone-3 concentrations are significantly higher than reported worldwide, and the average triclosan concentration was more than one order of magnitude higher than in many other populations. This study provides the first data on exposure of the general Australian population to a range of common personal care product chemical ingredients, which appears to be prevalent and warrants further investigation.

    A new specimen of the bizarrely specialised Malleodectes mirabilis from middle Miocene deposits in the Riversleigh World Heritage Area provides the first and only information about the molar dentition of this strange group of extinct marsupials. Apart from striking autapomorphies such as the enormous P3, other dental features such as stylar cusp D being larger than B suggest it belongs in the Order Dasyuromorphia. Phylogenetic analysis of 62 craniodental characters places Malleodectes within Dasyuromorphia albeit with weak support and without indication of specific relationships to any of the three established families (Dasyuridae, Myrmecobiidae and Thylacinidae). Accordingly we have allocated Malleodectes to the new family, Malleodectidae. Some features suggest potential links to previously named dasyuromorphians from Riversleigh (e.g., Ganbulanyi) but these are too poorly known to test this possibility. Although the original interpretation of a steeply declining molar row in Malleodectes can be rejected, it continues to seem likely that malleodectids specialised on snails but probably also consumed a wider range of prey items including small vertebrates. Whatever their actual diet, malleodectids appear to have filled a niche in Australia’s rainforests that has not been occupied by any other mammal group anywhere in the world from the Miocene onwards.

    Full Text Available Ultrafine particles are particles that are less than 0.1 micrometres (µm in diameter. Due to their very small size they can penetrate deep into the lungs, and potentially cause more damage than larger particles. The Ultrafine Particles from Traffic Emissions and Children’s Health (UPTECH study is the first Australian epidemiological study to assess the health effects of ultrafine particles on children’s health in general and peripheral airways in particular. The study is being conducted in Brisbane, Australia. Continuous indoor and outdoor air pollution monitoring was conducted within each of the twenty five participating school campuses to measure particulate matter, including in the ultrafine size range, and gases. Respiratory health effects were evaluated by conducting the following tests on participating children at each school: spirometry, forced oscillation technique (FOT and multiple breath nitrogen washout test (MBNW (to assess airway function, fraction of exhaled nitric oxide (FeNO, to assess airway inflammation, blood cotinine levels (to assess exposure to second-hand tobacco smoke, and serum C-reactive protein (CRP levels (to measure systemic inflammation. A pilot study was conducted prior to commencing the main study to assess the feasibility and reliably of measurement of some of the clinical tests that have been proposed for the main study. Air pollutant exposure measurements were not included in the pilot study.

  9. Water planning in the Condamine Alluvium, Queensland: Sharing information and eliciting views in a context of overallocation

    2012-12-01

    SummaryThe Central Condamine Alluvium, at the head of Australia's Murray-Darling River system, provides groundwater for food, fibre and a fast expanding urban population. Current extraction is assessed at 67 GL/a (gigalitres per annum), while the best available scientific data estimates the sustainable groundwater system yield is closer to 40 GL/a (CSIRO, 2008). Peak organisations accept overallocation as a critical issue but conflict over water has disrupted several past attempts at regulation. To assist local communities and the planning agency, seven planning tools were used: (1) an extended stakeholder analysis and context report, (2) a program of engagement with Traditional Custodians, (3) intergenerational workshops, (4) a survey of groundwater users covering issues in setting and meeting the agreed system yield, (5) a multi-criteria analysis relating to setting and apportioning the available yield, (6) a pilot workshop addressing adaptation to climate risk, and (7) development of a three-dimensional groundwater visualisation tool relating to the regional aquifers. Results fed directly into pre-planning processes undertaken by the State water agency. The tools allowed a much broader range of voices, values and depth of information to feed into the planning process than otherwise available. Participants found the Indigenous engagement tool and the GVT the most useful. The latter addressed identified information gaps and allowed for aquifer characteristics and the interaction with bores to be presented in a user-friendly manner. Intergenerational perspectives about using water within sustainable limits were also obtained but the Community Reference Panel did not place any weight on this perspective in discussions over the plan amendment. Evaluations of the tools demonstrate that a range of planning tools can be readily used to enhance existing planning processes, particularly by sharing information and eliciting views that may not be readily accessible to water planners.

  10. Age, distribution, and significance within a sediment budget, of in-channel depositional surfaces in the Normanby River, Queensland, Australia

    We present the results of investigations into alluvial deposition in the catchment of the Normanby River, which flows into Princess Charlotte Bay (PCB) in the northern part of the Great Barrier Reef Lagoon. Our focus is on the fine fraction (expansive flat surface generally referred to as the floodplain. Variously described as benches, bank attached bars or inset or inner floodplains, these more or less flat-lying surfaces within the macro-channel have hitherto received little attention in sediment budgeting models. We use high resolution LiDAR based mapping combined with optical dating of exposures cut into these in-channel deposits to compare their aggradation rates with those found in other depositional zones in the catchment, namely the floodplain and coastal plain. In total 59 single grain OSL dates were produced across 21 stratigraphic profiles at 14 sites distributed though the 24 226 km2 catchment. In-channel storage in these inset features is a significant component of the contemporary fine sediment budget (i.e. recent decades/last century), annually equivalent to more than 50% of the volume entering the channel network from hillslopes and subsoil sources. Therefore, at the very least, in-channel storage of fine material needs to be incorporated into sediment budgeting exercises. Furthermore, deposition within the channel has occurred in multiple locations coincident in time with accelerated sediment production following European settlement. Generally, this has occurred on a subset of the features we have examined here, namely linear bench features low in the channel. This suggests that accelerated aggradation on in-channel depositional surfaces has been in part a response to accelerated erosion within the catchment. The entire contribution of ~ 370 kilotonnes per annum of fine sediment estimated to have been produced by alluvial gully erosion over the last ~ 100 years can be accounted for by that stored as in-channel alluvium. These features therefore can play an important role in mitigating the impact on the receiving water of accelerated erosion.

    2013-09-01

    The strength of mental health nursing and its potential contribution to improved consumer outcomes depends upon strong and clearly articulated leadership. However, studies of leadership have tended to focus on nurses holding senior positions rather than exploring the leadership embedded in clinical work. A qualitative exploratory study was undertaken with identified mental health nurse leaders in one Australian state, in order to explore their experiences and what they found to be most meaningful in their work. This article reports the findings from this study. The data was analysed thematically to yield insights significant to mental health nursing and identity. The findings suggest these leaders find intrinsic rewards in the role; aspire to making authentic connections with consumers; appreciate the position of trust that they hold in bearing witness to individuals' distress; and use creative means to solve problems and achieve therapeutic outcomes. Sharing these themes builds knowledge on values that are embedded in mental health nursing practice and offers scope for integrating leadership attributes into the education, supervision and development of all mental health nurses. These findings also reveal the complexity of mental health nursing as a profession and the difficulties that might be encountered in attempts to define it in terms of its component tasks and functions.

  16. Patterns of tree dieback in Queensland, Australia: the importance of drought stress and the role of resistance to cavitation.

    2004-04-01

    During the extreme 1992-1997 El Niño drought event, widespread stem mortality, or tree "dieback", of both mature and juvenile eucalypts occurred within the tropical savannas of northeast Australia. Most of the dieback occurred in individuals of the ironbark species complex ( Eucalyptus crebra- E. xanthoclada) while individuals of the bloodwood species Corymbia erythrophloia, exhibited significantly less stem mortality. Indicative of greater water stress, predawn and midday xylem water potentials of ironbark adults and saplings were significantly more negative than predawn values of bloodwoods. The very negative xylem water potentials in ironbarks suggest that stem mortality in both adult and juvenile ironbarks results from drought-induced embolism and that ironbarks perhaps have a shallower and less extensive root system than bloodwoods. Although predawn and midday water potentials for ironbark adults and saplings were similar, a census of mature and juvenile ironbark trees indicated that mortality was higher in adult trees. Cavitation vulnerability curves indicated that ironbark saplings may be better buffered against cavitation than adult trees. If they possess smaller root systems, saplings are more likely than adults to experience low xylem water potentials, even in non-drought years. Xylem conduits produced in adult trees during periods of normal rainfall, although perhaps more efficient in water conduction, may be more vulnerable to cavitation during infrequent severe droughts.

    This report summarises the findings from a case of naturally-occurring Murray Valley encephalitis in a 2-year-old filly presenting with acute onset of depression and weakness. Serum samples tested at the onset of clinical signs were negative for Hendra and Kunjin virus antibodies, but positive for Murray Valley encephalitis virus (MVEV) using IgM-capture ELISA (1 : 300 dilution). A virus neutralisation assay performed 4 weeks later confirmed a titre of 1 : 160. Sera collected in the weeks preceding neurological signs returned a negative titre for MVEV 2 weeks prior followed by a titre of 1:80 in the week prior to illness. Serological surveillance conducted on 67 co-located horses returned a positive titre of 1 : 20 in one in-contact horse. There was no history of clinical disease in that horse. At 3 months after the onset of clinical signs in the index case, the filly continued to show mild facial paresis and hypermetria; the owners elected euthanasia and gave permission for necropsy. Histopathological analysis of the brain showed a mild meningoencephalitis. The progression of a naturally-occurring MVEV infection in a horse has been documented in this case. © 2015 Australian Veterinary Association.

    2004-01-01

    In this paper, the contributions from the three major erosion sources in the catchments of Moreton Bay are quantified, specifically for the erosion sources are classified as (i) sheet erosion from cultivated land, (ii) sheet erosion from uncultivated land, and (iii) subsoil erosion from gullies and channels. The catchments were the Brisbane and Logan rivers as well as the coastal catchments. A GIS based analysis of erosion risk was used to define areas of high erosion potential in each of the erosion source types. Radionuclide concentrations of 137Cs and 226Ra were measured on the soils from these areas and then compared to concentrations on the same size fraction on deposited sediments within the rivers. A mixing model was then used to calculate the contributions from the different sources to the sediments. The contributions in the Brisbane and Logan catchments were found to be subsoil erosion (approximately 66 +/- 10%); sheet erosion from cultivated lands 33 +/- 10% and sheet erosion of uncultivated land 1 +/- 10%. Surface and subsoil erosion contributions from the coastal catchments were found to be variable.

  19. Biosecurity and the management of emergency animal disease among commercial beef producers in New South Wales and Queensland (Australia).

    Australia places great importance on the prevention and management of emergency animal diseases (EAD), with strict quarantine measures offshore and at the border. Livestock producers are crucial for disease control onshore; however, limited information is available on commercial livestock producers' practices in relation to the management of disease risks. The aims of this paper are to investigate how commercial beef producers in Australia's Northern and Southern beef zones manage EADs and to identify drivers for effective biosecurity and EAD prevention. This paper forms part of a broader mixed methods research project involving an analysis of literature and current policies, qualitative semi-structured interviews with government and industry stakeholders and a cross-sectional study among beef producers. The cross-sectional study used a postal survey (n=182) and face-to-face interviews (n=34) to gather data on beef producers' knowledge and practices on biosecurity and EADs and their communication networks. Findings indicate that producers are uncertain about the roles and responsibilities of stakeholders involved in biosecurity and EAD management. This uncertainty may create confusion about EAD management and impact upon producers' willingness to report animal disease, with over 20% reporting the last veterinary contact more than five years ago and an additional 8.5% who had never contacted a veterinarian. Producers had a generally high awareness of the key sources of animal disease risk and they prioritise herd health planning as part of their everyday practices. Over 40% of producers had limited knowledge of the meaning of EAD; and EAD and biosecurity planning was given a low priority, primarily due to the perceived limited likelihood of an EAD event in Australia and the belief that EAD prevention is primarily the role of government. Only a moderate implementation of biosecurity practices, such as isolating incoming animals, having a single property entry point or keeping visitors' records was reported. If faced with an unusual disease event, most producers would contact their private or government veterinarian; however, in some instances most would also treat themselves and over a third would do nothing. Findings from this study suggest that there is a need for better coordination between stakeholders to encourage a shared biosecurity and EAD understanding and to communicate a consistent message to all stakeholders including producers. Further, there is a need for improving producer awareness of the importance of EAD prevention and biosecurity practices as well as the stakeholders' roles within the broader animal health system.

    Increases in the elevation of the soil surfaces of mangroves and salt marshes are key to the maintenance of these habitats with accelerating sea level rise. Understanding the processes that give rise to increases in soil surface elevation provides science for management of landscapes for sustainable coastal wetlands. Here, we tested whether the soil surface elevation of mangroves and salt marshes in Moreton Bay is keeping up with local rates of sea level rise (2.358 mm y-1) and whether accretion on the soil surface was the most important process for keeping up with sea level rise. We found variability in surface elevation gains, with sandy areas in the eastern bay having the highest surface elevation gains in both mangrove and salt marsh (5.9 and 1.9 mm y-1) whereas in the muddier western bay rates of surface elevation gain were lower (1.4 and -0.3 mm y-1 in mangrove and salt marsh, respectively). Both sides of the bay had similar rates of surface accretion (~7–9 mm y-1 in the mangrove and 1–3 mm y-1 in the salt marsh), but mangrove soils in the western bay were subsiding at a rate of approximately 8 mm y-1, possibly due to compaction of organic sediments. Over the study surface elevation increments were sensitive to position in the intertidal zone (higher when lower in the intertidal) and also to variation in mean sea level (higher at high sea level). Although surface accretion was the most important process for keeping up with sea level rise in the eastern bay, subsidence largely negated gains made through surface accretion in the western bay indicating a high vulnerability to sea level rise in these forests.

    Despite its global abundance, Bacillus pumilus is poorly studied. The Fairview strain was obtained from a methanogenic anaerobic coal digester. The draft genome sequence was 3.8 Mbp long and contained 3,890 protein-coding genes. Like the SAFR-032 strain, it includes B. pumilus-specific proteins that likely confer enhanced resistance to environmental stresses.

    The current study examined the effects of a natural disaster (a sudden onset flood) as a stressor in pregnancy on infant fine and gross motor development at 2, 6, and 16 months of age. Whether the timing of the stressor in pregnancy or sex of the infant moderated the impact of the prenatal maternal stress on motor development was also explored. Mothers' objective experiences of the flood, emotional reactions and distress, and their cognitive appraisal of the event were assessed retrospectively. Infants' fine and gross motor skills were assessed with the Ages and Stages Questionnaire, and results showed age-related changes in the effects of prenatal maternal stress on these domains. At 2 months, higher levels of prenatal maternal stress was positively related to infant motor development, yet at 6 and 16 months of age there was a negative association, particularly if flood exposure occurred later in pregnancy and if mothers had negative cognitive appraisals of the event. Results also showed differential effects of the maternal stress responses to the floods on infants' fine and gross motor development at each age and that infant sex did not buffer these effects. © 2016 Wiley Periodicals, Inc.

    During revegetation, the maintenance of soil carbon (C) pools and nitrogen (N) availability is considered essential for soil fertility and this study aimed to evaluate contrasting methods of site preparation (herbicide and scalping) with respect to the effects on soil organic matter (SOM) during the critical early establishment phase. Soil total C (TC), total N (TN), hot-water extractable organic C (HWEOC), hot-water extractable total N (HWETN), microbial biomass C and N (MBC and MBN), total inorganic N (TIN) and potentially mineralizable N (PMN) were measured over 53 weeks. MBC and MBN were the only variables affected by herbicide application. Scalping caused an immediate reduction in all variables, and the values remained low without any sign of recovery for the period of the study. The impact of scalping on HWETN and TIN lasted 22 weeks and stabilised afterwards. MBC and MBN were affected by both herbicide and scalping after initial treatment application and remained lower than control during the period of the study but did not decrease over time. While scalping had an inevitable impact on all soil properties that were measured, that impact did not worsen over time, and actually improved plant growth (unpublished data) while reducing site establishment costs. Therefore, it provides a useful alternative for weed control in revegetation projects where it is applied only once at site establishment and where SOM would be expected to recover as canopy closure is obtained and nutrient cycling through litterfall commences.

    Full Text Available Water use and depth of water extraction of leucaena (Leucaena leucocephala and Rhodes grass (Chloris gayana pasture, irrigated with desalinated coal seam water (a by-product of the coal seam gas industry, were monitored to provide background information on root activity, spatial and temporal water use and deep drainage over a 757-day period from August 2011 to August 2013. Methodology comprised measurement of soil water from surface to 4 m depth using 8 EnviroSCAN probes connected to dataloggers positioned within leucaena twin rows and within the Rhodes grass inter-row. Just over 581,000 individual moisture measurements were collated and are reported here. Water extraction (and by inference root activity of leucaena and Rhodes grass showed marked seasonal fluctuation with deepest and highest water extraction occurring during the first growing season; water extraction was greatly diminished during the following drier and cooler seasons due to the negative influences of lower soil moisture contents, lower temperatures and increased defoliation on pasture growth. The highest values of deep drainage below 4 m depth occurred when high rainfall events corresponded with high soil water storage in the entire profile (0–4 m depth. Given that water usage by both leucaena and Rhodes grass was greatest in the upper layers of soil (<1.5 m, future research should focus on how the level of competitive interaction might be managed by choice of row spacing and frequency of irrigation. Further studies are needed, including: (a physical sampling to determine the depth of active roots; (b how defoliation affects rooting behaviours and water use of leucaena; and (c modelling of the water and salt balances of leucaena and grass inter-row systems using data from this study, with various levels of irrigation, to investigate the risks of deep drainage over an extended climate sequence.Keywords: Active rooting depth, agroforestry, Chloris gayana, Leucaena leucocephala, water extraction.DOI: 10.17138/TGFT(4129-138

  10. Applying econometric techniques to hydrological problems in a large basin: Quantifying the rainfall-discharge relationship in the Burdekin, Queensland, Australia

    2013-07-01

    This study seeks to explore the relationship between rainfall and river discharge within a large river basin flowing into the waters surrounding the Great Barrier Reef (GBR), and to investigate the best method of measuring the relationship. This aim is addressed by focusing on three specific research questions: (A) Has there been any evidence that global climate change has impacted on either rainfall or river discharge resulting in any change to the relationship between these variables over time? (B) What is the best measure of rainfall to be used to quantify the rainfall-discharge relationship, including the optimal number of rain stations to be included in the sample? (C) What is the optimal temporal scale for measuring the relationship (ranging from fine scale monthly data, medium scale quarterly data, and coarse scale annual data)? Modern econometric time series techniques are utilised, and compared with results using an alternate technique developed by researchers from the bio-physical sciences; the widely used Thiessen Polygon method. Firstly, stationarity testing, using econometric unit root tests, did not find evidence to suggest that the data are non-stationary. Evidently, climate change has not had a measurable impact on rainfall or river discharge in the region during the period covered by this study. Secondly, the analysis shows that the when dealing with fairly simple models with a fairly small number of explanatory variables, those which best represent the river-discharge relationship are those using the coarser scales (both geographic and temporal). In other words, stronger and more robust results are derived from models using fewer rain stations, and annual data (rather than quarterly or monthly data). This approach provides a viable alternative that may be very useful in data-poor environments when it is not possible to use other more data-hungry modelling approaches. The econometric models provided a better explanation of the relationship than the Thiessen Polygon approach, whilst utilising data from a smaller number of rain stations. The most appropriate functional form was that using the natural logs of discharge as the dependent variable, and the relationship appears to be a fairly simple one, with the inclusion of lagged data from previous years not significantly improving the explanation provided by current year models. The approach demonstrates that simple time series models can be enriched by the incorporation of additional variables beyond rainfall levels; both temperatures and rainfall concentration were considered with the inclusion of a rainfall concentration index proving to significantly improve the explanatory power of the model for this study region.

    Asquith, Catherine; Kimble, Roy; Stockton, Kellie

    2015-02-01

    The aim of this study was to quantify and describe the characteristics of burns in children caused by sun heated surfaces. Children presenting between January 2013 and February 2014 with a burn due to sun heated surfaces were included in the study. Fifteen children were identified representing 1.7% of new burns. The mean age was 18.3 months. All burns occurred during the warmer months between 11a.m. and 4p.m. and the feet were commonly involved. Most cases occurred in the child's home garden but six cases occurred in public play areas. Metal was the most common surface involved. Most burns were superficial partial thickness with two burns deep dermal partial thickness and one child needed a skin graft. Burns due to sun heated surfaces are relatively frequent. Parents need to be aware that in summer surfaces can become hot enough to cause burns to bare feet in young children. Play areas need to be shaded or covered in surfaces that do not become hot enough to cause burns and metal objects should not be left in the sun in children's play areas.

  13. Effect of nitrification inhibitors (DMPP and 3MP+TZ) on soil nitrous oxide emissions from a sub-tropical vegetable production system in Queensland, Australia

    2015-04-01

    The use of nitrification inhibitors, in combination with ammonium based fertilisers, has been promoted recently as an effective method to reduce nitrous oxide (N2O) emissions from fertilised agricultural fields, whilst increasing yield and nitrogen use efficiency. Vegetable cropping systems are often characterised by high inputs of nitrogen fertiliser and consequently elevated emissions of nitrous oxide (N2O) can be expected. However, to date only limited data is available on the use of nitrification inhibitors in sub-tropical vegetable systems. A field experiment investigated the effect of the nitrification inhibitors (DMPP & 3MP+TZ) on N2O emissions and yield from a typical vegetable production system in sub-tropical Australia. Soil N2O fluxes were monitored continuously over an entire year with a fully automated system. Measurements were taken from three subplots for each treatment within a randomized complete blocks design. There was a significant inhibition effect of DMPP and 3MP+TZ on N2O emissions and soil mineral N content directly following the application of the fertiliser over the vegetable cropping phase. However this mitigation was offset by elevated N2O emissions from the inhibitor treatments over the post-harvest fallow period. Cumulative annual N2O emissions amounted to 1.22 kg-N/ha, 1.16 kg-N/ha, 1.50 kg-N/ha and 0.86 kg-N/ha in the conventional fertiliser (CONV), the DMPP treatment, the 3MP+TZ treatment and the zero fertiliser (0N) respectively. Corresponding fertiliser induced emission factors (EFs) were low with only 0.09 - 0.20% of the total applied fertiliser lost as N2O. There was no significant effect of the nitrification inhibitors on yield compared to the CONV treatment for the three vegetable crops (green beans, broccoli, lettuce) grown over the experimental period. This study highlights that N2O emissions from such vegetable cropping system are primarily controlled by post-harvest emissions following the incorporation of vegetable crop residues into the soil. It also shows that the use of nitrification inhibitors can lead to elevated N2O emissions by storing N in the soil profile that is available to soil microbes during the decomposition of the vegetable residues over the post-harvest phase. Hence the use of nitrification inhibitors in vegetable systems has to be treated carefully and fertiliser rates need to be adjusted to avoid excess soil nitrogen during the postharvest phase.

    1987-01-01

    In an attempt to improve the land cover/use classification accuracy obtainable from remotely sensed multispectral imagery, Airborne Imaging Spectrometer-1 (AIS-1) images were analyzed in conjunction with Thematic Mapper Simulator (NS001) Large Format Camera color infrared photography and black and white aerial photography. Specific portions of the combined data set were registered and used for classification. Following this procedure, the resulting derived data was tested using an overall accuracy assessment method. Precise photogrammetric 2D-3D-2D geometric modeling techniques is not the basis for this study. Instead, the discussion exposes resultant spectral findings from the image-to-image registrations. Problems associated with the AIS-1 TMS integration are considered, and useful applications of the imagery combination are presented. More advanced methodologies for imagery integration are needed if multisystem data sets are to be utilized fully. Nevertheless, research, described herein, provides a formulation for future Earth Observation Station related multisensor studies.

  18. Homelessness in Queensland mining communities: A down payment on Australia’s wealth or inevitable product of a neo-liberalist society’s response to the cyclical fortunes of mining

    Directory of Open Access Journals (Sweden)

    Shane Matthew Warren

    2015-09-01

    Full Text Available The mining boom in Australia of the first decade of the Twenty-First Century yielded prosperity for many Australians living in rural, regional and urban locations. This sense of prosperity was grounded in the widely reported experiences of people usually employed directly through the mining industry, or related industry, on high incomes, able to afford regular overseas holidays, ownership of multiple properties, material possessions and other hallmarks of an affluent lifestyle. However, less attention was given to vulnerable and homeless Australians in mining communities who did not benefit at all during the mining boom. In fact what evidence does exist indicates their disadvantage was further compounded through the high cost of housing. It is now widely accepted that the mining industry has been in a state of downturn over the last three years and this has served to highlight the social issues facing mining communities now and into the future. What is to be learnt from the decade long mining boom? Specifically this paper critiques the evidence, research literature and theories about urban-centric homelessness and assesses their relevance to homelessness in mining communities. This paper argues that the dynamics of homelessness in mining communities challenge existing homelessness theory and knowledge and argues that further evidence is needed to properly understand structural causes of homelessness in mining communities and to guide policy responses that may help prevent homelessness or otherwise assist homeless people access housing and support services. Identifying the mining boom and mining downturn cycle will be explored. Finally this paper outlines the case for further research to improve policy and planning responses to address homelessness in these communities taking into account planning requirements to address the mining boom and down turn cycle.

  20. Can remote infrared cameras be used to differentiate small, sympatric mammal species? A case study of the black-tailed dusky antechinus, Antechinus arktos and co-occurring small mammals in southeast Queensland, Australia.

    Gray, Emma L; Dennis, Todd E; Baker, Andrew M

    2017-01-01

    The black-tailed dusky antechinus (Antechinus arktos) is an endangered, small carnivorous marsupial endemic to Australia, which occurs at low population density along with abundant sympatric populations of other small mammals: Antechinus stuartii, Rattus fuscipes and Melomys cervinipes. Using A. arktos as a model species, we aimed to evaluate the effectiveness of infrared digital camera traps for detecting and differentiating small mammals and to comment on the broad applicability of this methodology. We also sought to understand how the detection probabilities of our target species varied over time and characterize their activity patterns. We installed 11 infrared cameras at one of only three known sites where A. arktos occurs for five consecutive deployments. Cameras were fixed to wooden stakes and oriented vertically, 35 cm above ground, directly facing bait containers. Using this method, we successfully recorded and identified individuals from all four species of small mammal known previously in the area from live trapping, including A. arktos. This validates the effectiveness of the infrared camera type and orientation for small mammal studies. Periods of activity for all species were highly coincident, showing a strong peak in activity during the same two-hour period immediately following sunset. A. arktos, A. stuartii and M. cervinipes also displayed a strong negative linear relationship between detection probability and days since deployment. This is an important finding for camera trapping generally, indicating that routine camera deployment lengths (of one-to-two weeks) between baiting events may be too long when targeting some small mammals.

  1. Genetic variation in the mitochondrial cytochrome c oxidase subunit 1 within three species of Progamotaenia (Cestoda: Anoplocephalidae) from macropodid marsupials.

    2005-01-01

    Sequence variation within 3 morphologically defined species of the anoplocephalid cestode genus Progamotaenia (P. ewersi, P. macropodis and P. zschokkei) was investigated using the cytochrome c oxidase subunit 1 gene. The magnitude of genetic variation detected within each morphospecies suggests that, in each instance, several cryptic species are present. Within P. ewersi, 5 genetically distict groups of cestodes were detected, 1 shared by Macropus robustus and M. parryi in Queensland, 1 in M. agilis from Queensland, 1 in Petrogale assimilis from Queensland, 1 in Macropus fuliginosus from South Australia and 1 in Wallabia bicolor from Victoria. In P. macropodis, cestodes from M. robustus from Queensland, Western Australia and the Northern Territory, M. parryi from Queensland and M. eugenii from South Australia were genetically distinct from those in Wallabia bicolor from Queensland and Victoria and from M. fuliginosus from South Australia. P. zschokkei consisted of a number of genetically distinct groups of cestodes, 1 in Lagorchestes conspicillatus and L. hirsutus from Queensland and the Northern Territory respectively, 1 in Petrogale herberti, P. assimilis and M. dorsalis from Queensland, 1 in Onychogalea fraenata from Queensland, 1 in M. agilis from Queensland and 1 in Thylogale stigmatica and T. thetis from Queensland. In general, genetic groups within each morphospecies were host specific and occurred predominantly in a particular macropodid host clade. Comparison of genetic relationships of cestodes with the phylogeny of their hosts revealed examples of colonization (P. zschokkei in M. agilis) and of host switching (P. zschokkei in M. dorsalis).

Debate exists regarding the extent to which the activities of these groups should be formalized. Results drawn from an evaluation of a large-scale peer group supervision initiative are described. Analysis of 192 responses from professionals involved in peer groups indicates that participants in groups that used formal documentation – which adopted the tools provided in training, and particularly those that used formal evaluation of their groups – rated their groups as having better processes and greater impact. Interestingly, multidisciplinary peer groups were rated as having similar impacts, processes, and purposes as the more homogenous single-discipline groups. It is concluded that the implementation of formal arrangements enhances the processes and outcomes of peer groups implemented for professional support and clinical supervision. Multidisciplinary membership of such groups is perceived as equally beneficial as single-discipline groups.

    Queensland has the highest rates of skin cancer in the world and due to the high levels of solar UV in this region it is assumed that incidental UV exposure should provide adequate vitamin D status for the population. This research was undertaken to test this assumption among healthy free-living adults in south-east Queensland, Australia (27°S), at the end of winter. This research was approved by Queensland University of Technology Human Research Ethics Committee and conducted under the guidelines of the Declaration of Helsinki. 10.2% of the sample had serum vitamin D levels below 25nm/L (deficiency) and a further 32.3% had levels between 25nm/L and 50nm/L (insufficiency). Vitamin D deficiency and insufficiency can occur at the end of winter, even in sunny climates. The wintertime UV levels in south-east Queensland (UV index 4-6) are equivalent to summertime UV levels in northern regions of Europe and the USA. These ambient UV levels are sufficient to ensure synthesis of vitamin D requirements. We investigated individual UV exposure (through a self reported sun exposure questionnaire) and found correlations between exposure and Vitamin D status. Further research is needed to explore the interactions between the solar UV environment and vitamin D status, particularly in high UV environments, such as Queensland.

  9. Corneal fibropapillomatosis in green sea turtles (Chelonia mydas) in Australia.

    2010-05-01

    Chelonid corneal fibropapillomatosis has not previously been recorded in Australian waters. During 2008, 724 green sea turtles (Chelonia mydas) were examined in Queensland, Australia at two sites, Moreton Bay (n=155) and Shoalwater Bay (n=569), during annual monitoring. In the same calendar year, 63 turtles were submitted from various sites in southern Queensland for post-mortem examination at the University of Queensland. Four of the 787 animals (0.5%) were found to have corneal fibropapillomas of varying size, with similar gross and microscopical features to those reported in other parts of the world. Two animals with corneal fibropapillomas also had cutaneous fibropapillomas. Clinical assessment indicated that these lesions had detrimental effects on the vision of the turtles and therefore their potential ability to source food, avoid predators and interact with conspecifics. Importantly, these findings represent an emergence of this manifestation of fibropapillomatosis in green sea turtle populations in the southern Pacific Ocean.

    The purpose of this paper is to investigate the quality of management practices of public hospitals in the Australian healthcare system, specifically those in the state-managed health systems of Queensland and New South Wales (NSW). Further, the authors assess the management practices of Queensland and NSW public hospitals jointly and globally benchmark against those in the health systems of seven other countries, namely, USA, UK, Sweden, France, Germany, Italy and Canada. In this study, the authors adapt the unique and globally deployed Bloom et al. (2009) survey instrument that uses a "double blind, double scored" methodology and an interview-based scoring grid to measure and internationally benchmark the management practices in Queensland and NSW public hospitals based on 21 management dimensions across four broad areas of management - operations, performance monitoring, targets and people management. The findings reveal the areas of strength and potential areas of improvement in the Queensland and NSW Health hospital management practices when compared with public hospitals in seven countries, namely, USA, UK, Sweden, France, Germany, Italy and Canada. Together, Queensland and NSW Health hospitals perform best in operations management followed by performance monitoring. While target management presents scope for improvement, people management is the sphere where these Australian hospitals lag the most. This paper is of interest to both hospital administrators and health care policy-makers aiming to lift management quality at the hospital level as well as at the institutional level, as a vehicle to consistently deliver sustainable high-quality health services. This study provides the first internationally comparable robust measure of management capability in Australian public hospitals, where hospitals are run independently by the state-run healthcare systems. Additionally, this research study contributes to the empirical evidence base on the quality of

    There are few data available on which to estimate the risk of death for Australian divers. This report estimates the risk of a scuba diving fatality for Australian residents, international tourists diving in Queensland, and clients of a large Victorian dive operator. Numerators for the estimates were obtained from the Divers Alert Network Asia-Pacific dive fatality database. Denominators were derived from three sources: Participation in Exercise, Recreation and Sport Surveys, 2001-2010 (Australian resident diving activity data); Tourism Research Australia surveys of international visitors to Queensland 2006-2014 and a dive operator in Victoria 2007-2014. Annual fatality rates (AFR) and 95% confidence intervals (95% CI) were calculated using an exact binomial test. Estimated AFRs were: 0.48 (0.37-0.59) deaths per 100,000 dives, or 8.73 (6.85-10.96) deaths per 100,000 divers for Australian residents; 0.12 (0.05-0.25) deaths per 100,000 dives, or 0.46 (0.20-0.91) deaths per 100,000 divers for international visitors to Queensland; and 1.64 (0.20-5.93) deaths per 100,000 dives for the dive operator in Victoria. On a per diver basis, Australian residents are estimated to be almost twenty times more likely to die whilst scuba diving than are international visitors to Queensland, or to lower than fourfold on a per dive basis. On a per dive basis, divers in Victoria are fourteen times more likely to die than are Queensland international tourists. Although some of the estimates are based on potentially unreliable denominator data extrapolated from surveys, the diving fatality rates in Australia appear to vary by State, being considerably lower in Queensland than in Victoria. These estimates are similar to or lower than comparable overseas estimates, although reliability of all such measurements varies with study size and accuracy of the data available.

  12. Collapse and revival of the monopole mode of a Bose-Einstein condensate in a spherical harmonic trap

    We observe the relaxation of the monopole (breathing) mode of a rubidium-87 Bose-Einstein condensate (BEC) in a highly spherical harmonic trap at finite temperature. The experiments show a collapse and revival of the condensate oscillation, consistent with numerical simulations of the system using the Zaremba-Nikuni-Griffin methodology for the nonequilibrium dynamics of BECs. The beating signal is shown to be due to the resonant excitation of the ``out-of-phase'' normal mode of the condensate and thermal cloud.

    Art therapy encompasses both preventative and curative activities and aims to improve ways of engaging those who might be reticent in seeking more traditional forms of psychological support offered through 'talking therapies'. The Longreach base of the Royal Flying Doctor Service in Queensland provides mental health support to people living in rural and remote locations in central western Queensland and has been complemented since 2006 by the addition of a full-time art therapist. This paper provides an overview of art therapy and a description of this innovative approach to addressing mental health needs in a rural and remote setting.

    Of 134 Queensland passengers on a cruise, 91 (67.9%) people reported various illnesses including 41 (30.6%) who reported diarrhoeal symptoms. Queensland passengers who ate while onshore at non-Australian ports were significantly more at risk of developing diarrhoeal symptoms than those who did not. Passengers were particularly at risk when they ate onshore while undertaking a tour compared with those who did not undertake this tour. Travellers should be warned of the possibility of contracting diarrhoeal illness from onshore catering.

    Weaver ants (Oecophylla smaragdina) are dominant ants in open forests from India, Australia, China and Southeast Asia, whose leaf nests are held together with larval silk. The species, together with its sole congener O. longinoda, has been important in research on biological control, communication, territoriality and colony integration. Over most of the range, only one queen has been found per colony, but the occurrence of several queens per nest has been reported for the Australian Northern Territory. The number of males mating with each queen is little known. Here we report on the colony structure of O. smaragdina using published and new microsatellite markers. Worker genotype arrays reflect the occurrence of habitual polygyny (more than one queen per colony) in 18 colonies from Darwin, Northern Australia, with up to five queens inferred per colony. Monogyny (one queen per colony) with occasional polygyny was inferred for 14 colonies from Queensland, Australia, and 20 colonies from Java, Indonesia. Direct genotyping of the sperm carried by 77 Queensland queens and worker genotypic arrays of established colonies yielded similar results, indicating that less than half of the queens mate only once and some mate up to five times. Worker genotype arrays indicated that queens from Java and the Northern Territory also often mate with more than one male, but less often than those from Queensland. A strong isolation-by-distance effect was found for Queensland samples. The variation uncovered means that O. smaragdina is a more versatile study system than previously supposed.

    2017-05-10

    The identity of Ewartia oldfieldi (Distant) is re-examined and this species is redescribed. Five new species belonging to the genus Ewartia Moulds are described. Ewartia oldfieldi s. str. occurs in association with wattles (Acacia spp.; Mimosaceae) with large or fleshy phyllodes growing in soils derived from sandstone and coarse-grained metasediments throughout the south-eastern third of Queensland. Ewartia roberti n. sp. is associated with wattles that possess narrow or delicate phyllodes, growing in loam soils in southern Queensland and northern New South Wales. Ewartia lapidosa n. sp. occurs in dryer inland and semi-arid areas between Croydon in northern Queensland and the Capertee Valley in central New South Wales where it occurs on various wattles growing in hard, rocky soils, including those derived from laterite and sandstone. Ewartia etesia n. sp. occurs principally on wattles growing along drainage lines in the Top End of the Northern Territory and the eastern edge of the Kimberley in Western Australia. Ewartia thamna n. sp. occurs in low, shrubby vegetation (presumably on wattles) in gravelly soils on low rises and along floodplains at the southern edge of the Top End in the Northern Territory. Ewartia carina n. sp. occurs in transitional habitats with tropical rainforest elements on the eastern edge of Cape York Peninsula in north Queensland. The distinctive, sometimes variable and typically complex calling songs specific to each of the species are illustrated and documented as part of these descriptions and comparisons.

VCR is particularly important for the treatment of acute lymphoblastic leukemia (ALL, a disease that accounts for approximately one-third of all childhood cancer diagnoses. VCR's full therapeutic potential has been limited by dose-limiting neurotoxicity, classically resulting in autonomic and peripheral sensory–motor neuropathy. In the last decade, however, the discovery that liposomal encapsulation of chemotherapeutics can modulate the pharmacokinetic characteristics of a compound has stimulated much interest in liposomal VCR (vincristine sulfate liposomal injection [VSLI] formulations for the treatment of ALL and other hematological malignancies. Promising data from recent clinical trials investigating VSLI in adults with ALL resulted in US Food and Drug Administration approval for use in patients with Philadelphia chromosome (t[9;22]/BCR–ABL1 (Ph-negative (Ph- disease. Additional clinical trials of VSLI in adults and children with both Ph-positive (Ph+ and Ph- ALL are ongoing. Here we review the preclinical and clinical experience to date with VSLI for ALL.Keywords: vincristine sulfate liposomal injection, liposomes, sphingosomal vincristine, acute lymphoblastic leukemia, chemotherapy
