  1. Japan's energy future: implications for Australia

    International Nuclear Information System (INIS)

    In April this year, the Department of Industry, Science and Resources published a report outlining the dilemmas facing Japan's energy industry in the post-Kyoto environment with particular reference to the effect it would have on Australia's fuel exports. The following article is based on information in that report. In summary, the extent to which the Japanese government's current climate change response policy (the long term energy forecast) is realised will depend on a complex interaction of competing considerations: 1. whether, in the event of US non ratification, the government maintains its Kyoto commitment or opts for a partial step back from its 8% commitment (and the extent of that draw back); 2. in the event that it does maintain its Kyoto commitment: a) the extent to which it takes advantage of the flexible mechanism provisions to ease the abatement burden on the energy system; b) the level of success in securing additional nuclear power stations and higher load ratios from nuclear power; c) the degree to which renewable and recycling energy sources can be brought on line; d) the extent to which the Japanese people are willing to meet the costs of switching to new technology and changing lifestyles to conserve energy; e) the timing of new initiatives such as emissions trading; the extent to which Japanese industry is able to achieve very strict energy conservation targets; f) the extent to which Japan's economic recovery leads to increased electricity demand as well as g) the extent to which electricity deregulation reduces prices and promotes increased consumption

    SummaryAnnual, monthly and daily streamflows from 99 unregulated rivers across northern Australia were analysed to assess the general surface water resources of the region and their implications for development. The potential for carry-over storages was assessed using the Gould-Dincer Gamma method, which utilises the mean, standard deviation, skewness and lag-one serial correlation coefficient of annual flows. Runs Analysis was used to describe the characteristics of drought in northern Australia and the potential for 'active' water harvesting was evaluated by Base Flow Separation, Flow Duration Curves and Spells Analysis. These parameters for northern Australia were compared with data from southern Australia and data for similar Köppen class from around the world. Notably, the variability and seasonality of annual streamflow across northern Australia were observed to be high compared with that of similar Köppen classes from the rest of the world (RoW). The high inter-annual variability of runoff means that carry-over storages in northern Australia will need to be considerably larger than for rivers from the RoW (assuming similar mean annual runoff, yield and reliability). For example, in the three major Köppen zones across the North, it was possible (theoretically) to only exploit approximately 33% (Köppen Aw; n = 6), 25% (Köppen BSh; n = 12) and 13% (Köppen BWh; n = 11) of mean annual streamflow (assuming a hypothetical storage size equal to the mean annual flow). Over 90% of north Australian rivers had a Base Flow Index of less than 0.4, 72% had negative annual lag-one autocorrelation values and in half the rivers sampled greater than 80% of the total flow occurred during the 3-month peak period. These data confirm that flow in the rivers of northern Australia is largely event driven and that the north Australian environment has limited natural storage capacity. Hence, there is relatively little opportunity in many northern rivers to actively harvest water

  3. Obituary: David Stanley Evans, 1916-2004

    Bash, Frank N.

    2005-12-01

    David Stanley Evans died on 14 November 2004 in Austin, Texas. He was a noted observational astronomer whose career was divided between South Africa and Texas. He also used the extensive historical collections at the University of Texas to write several books on the history of astronomy. He was born in Cardiff, Wales on 28 January 1916. David received his BA degree in mathematics in 1937 from Kings College, Cambridge. He became a PhD student at Cambridge Observatory in 1937, and was one of Sir Arthur Eddington's last surviving students. He received his PhD degree in 1941 with a dissertation entitled, "The Formation of the Balmer Series of Hydrogen in Stellar Atmospheres." He was a conscientious objector to war and, thus, spent the war years at Oxford working with physicist Kurt Mendelssohn on medical problems, involving cadavers, relating to the war. During these years, David was scientific editor of "Discovery", and he was editor of "The Observatory". David left England in 1946 in order to take up the position of Second Assistant at the Radcliffe Observatory, Pretoria, South Africa. He and H. Knox Shaw were the entire staff after R. O. Redman left, and they aluminized and installed the mirrors in the 74-inch telescope. His notable scientific contribution was to use lunar occultations to measure stellar angular diameters during the 1950s. He succeeded in determining the angular diameter of Antares and determined that Arcturus was not circular but had an elliptical shape. The elliptical shape was later shown to be an instrumental artifact, but the utility of using lunar occultations to measure stellar diameters and stellar multiplicity was conclusively demonstrated. T. Gold presented David's paper on lunar occultation angular diameters at the January 1953 meeting of the Royal Astronomical Society. For the rest of his life, David resented Gold's remarks, because he felt that he had been ridiculed. By 1953, David Evans was Chief Assistant at the Royal Observatory headquartered in Cape Town, South Africa. David had designed and built a Newtonian spectrograph for the 74-inch Radcliffe Telescope with which he measured the first southern galaxy redshifts. David and his family spent 1965-66 in Austin, Texas, where he was a National Science Foundation Senior Visiting Scientist at the University of Texas and McDonald Observatory. They moved permanently to Austin in 1968 and David became a Professor of Astronomy and Associate Director of McDonald Observatory at the University of Texas at Austin. At McDonald Observatory, R. E. Nather had devised a high-speed photometer capable of measuring millisecond time-scale changes in brightness and with Brian Warner, he invented "high-speed astronomy". This instrument caused Evans to revive his occultation program and, over the next twenty years, he produced the major part of the angular diameters of late-type stars with his students and collaborators. In addition, David and collaborators used the extensive collections of the University of Texas to write "Herschel at the Cape". David was also involved in observing the occultation of ? Sco by Jupiter in 1972 and in observing, during a solar eclipse in 1973, the gravitational deflections in the positions of stars whose light passes near to the Sun. The eclipse was observed from Mauritania, and the observations confirmed Einstein's prediction again. David Evans and his students studied late-type stars that have large star-spots and others that flare. In addition, they studied stars whose lunar occultation observations had revealed them to be double or even more than two stars. David Evans's major scientific contribution was an application of his stellar angular diameters to deduce the surface brightness of stars with the result that with suitable color indices one could use photometry to deduce the angular diameter of stars. This is applicable to stars which can never be occulted by the Moon, and its application to Cepheid variable stars has yielded their distances. This relation between angular diameters and a V-R color index is called the Barnes-Evans Relation. Tom Barnes gives most of the credit to Evans, but said that David insisted that the authors be listed in alphabetical order. This work was greeted with initial skepticism but it stimulated an enormous amount of interest and has been used to measure distances to 100 Cepheid variable stars in our galaxy. The method gives a distance to one of them, Delta Cephei, that agrees closely with recently measured parallaxes using HST. The Barnes-Evans method yields distances which are accurate to a few percent and is applicable to Cepheids in nearby galaxies. Before coming to Texas, David Evans had never given a large lecture course at a university, and his efforts met with mixed success especially in introductory classes for freshmen facing a "science requirement." David had considerably more success supervising PhD dissertations. He was supervisor for four. He was promoted to the position of Jack S. Josey Centennial Professor of Astronomy in 1984, which is the position he held until his retirement in 1986. He was awarded the Gill Medal of the Astronomical Society of South Africa in 1988. David Evans had a remarkable facility for language, especially English. He was an author of eight books including a 1966 edition of "Teach Yourself Astronomy", which was an introduction to astronomy and an inspiration to a number of currently active astronomers. He also loved history, especially of Southern Hemisphere astronomy but also of the McDonald Observatory. In fact, David continued to be very active after retirement and when he died he had completed a book (with Karen Winget) on the eclipse expedition to Mauritania, which is not yet printed.

    1989-03-01

    The smallest continent and one of the largest countries, Australia is a country of diverse geographical conditions and differing cultures of people unified by one predominant language and political system. Mountains, desert and rivers are some of the varying landscape features of Australia, although the climate and condition for most of the country is tropical. Original Australians, a hunting-gathering people called Aborigines, came to Australia over 38,000 years ago. Today the Aborigines compose about 1% of the population and live in traditional tribal areas as well as cities. The 1st European settlement came in 1788 from Great Britain. After World War II, the population doubled. Although the population is primarily composed of British and Irish immigrants, immigrants from other European countries such as Italy and Greece as well as refugees from Indochina, Vietnam, Cambodia and Laos are a significant factor to the growing Australian population. Australian and Aboriginal culture has took hold and took notice in the areas of opera, art, literature and film. The Australian Commonwealth is based on a constitution similar to that of the United States government. The National Parliament is bicameral with both the Senate and the House of Representatives having a select number of elected officials from each state and territory. The Australian economy is predominantly reliant on the sale of mineral and agricultural exports. History, economic changes, defense, international relations and notes to the traveler are also discussed in this overview of Australia. PMID:12177993

    Dengue outbreaks have increased in size and frequency in Australia, and transfusion-transmitted dengue poses a risk to transfusion safety. Using whole blood samples collected during the large 2008–2009 dengue epidemic, we estimated the risk for a dengue-infectious blood donation as ≈1 in 7,146 (range 2,218–50,021).

  6. Implications of climate change for skin cancer prevention in Australia.

    Science.gov (United States)

    Makin, Jen

    2011-12-01

    It is estimated that nearly 450,000 Australians get skin cancer every year. Ultraviolet (UV) radiation from sunlight has been identified as the cause of more than 95% of skin cancers in Australia. Accordingly, the focus of skin cancer prevention programs is reducing exposure to UV radiation. In Victoria, improvements in sun protection behaviours and reductions in sunburn and melanoma incidence rates among younger people have been observed since the SunSmart program was established in 1988. However, climate change has the potential to undermine these successes. First, surface UVB radiation is dependent on stratospheric total ozone amounts. While signs of impact of international restrictions on the production of ozone-depleting substances have been observed, improvements have not yet returned ozone to pre-1970s levels. Interactions between ozone depletion and climate change may slow the recovery of the ozone layer and compound increases in UV radiation at some latitudes. Before recovery, it is expected that higher levels of UV radiation will continue in most Australian regions, with an associated higher risk of skin cancer. Indeed, recent data show increases in surface UV radiation throughout Australia since the 1970s. Second, mean temperatures in Australia have increased over the past 30 years and are projected to rise further by 2030. Australian data shows that with higher temperatures, adults spend more time outdoors, are less likely to wear covering clothing and more likely to be sunburnt. Hence, rising temperatures can be expected to result in increases in sun exposure, sunburn and correspondingly, skin cancer risk. PMID:22518918

    This exploratory research examined adjustment challenges, resiliencies, attitudes, emotional health, economic stability, criminal involvement, victimization and service experiences, and some cultural propensities of Greek Immigrants (GIs) in Australia using a convenient multi-generational sample (n = 123; response rate = .5). Data were collected via surveys, telephone, and personal-interviews in four major Australian cities. Among other things, the study revealed that Greek identity and cultural customs are often significant to first generation GIs. Adjustment challenges upon entry include primarily language, housing, and transportation difficulties, nostalgia for relatives and the motherland, unfamiliarity with socio-cultural systems, unemployment, money challenges, and lack of friendships. Christian faith, the extended family, family values and traditions, cultural pride for ancient Greek achievements, and a hard 'work ethic' are notable resiliencies that support GIs in their struggles and solidify their pursuit for happiness and success. Financial concerns, aging, and nostalgia for relatives and the motherland were the primary causes of socio-emotional instability. Attitudinal differences in the respondents based on age, gender, and socio-economic status, cross-cultural comparisons, and recommendations for culturally-sensitive practice with GIs are analyzed and methodological limitations illuminated. Future research needs in the field are also highlighted. PMID:25376129

  8. The outlook for crude oil supply and demand in Australia and its energy policy implications

    International Nuclear Information System (INIS)

    Australia's oil reserves and production have contributed significantly to national economic prosperity and growth since the first large scale discoveries in Bass Strait in the 1960s. As a finite, non-renewable resource, the reserves ultimately must decline. In 1988 the forecast was that Australia's oil production would begin to decline in the mid 1990s and then rapidly tail off by the late 1990s. With this in mind, AMEC Ministers agreed in 1988 that a Working Group should review the energy policy implications of the forecast decline in the production of petroleum. The Working Group's findings are presented in this booklet. Chapter 2 examines the outlook for demand for petroleum products in Australia until 2005. This Chapter is based on current Australian Bureau of Agricultural and Resource Economics (ABARE) forecasts as well as savings in fuel demand that are potentially available from fuel efficiency and fuel switching measures. Chapter 3, which includes BMR's recently revised petroleum production forecasts, looks at the outlook for crude oil and condensate production, also to 2005. Chapter 4 discusses the range of government initiatives already in place to foster the efficient exploration and production of petroleum in Australia. This Chapter also examines the outlook for Australian alternative liquid fuels. Chapter 5, which is based on analysis by ABARE, broadly examines the possible macroeconomic implications of declining oil production for Australia while Chapter 6 examines the issue of energy security and in particular its relationship with oil self sufficiency. Finally, Chapter 7 identifies some energy policy considerations and recommendations arising out of the Working Group's analysis. 7 tabs, 3 figs

    The studies of Allen (2011) and Allen et al.(2011) revently examined the methodology underpinning claims that dingoes provide net benefits to biodiversity by suppressing foxes and cats.They found most studies to have design flaws and/or observational methods that preclude valid interpretations from the data,describing most of the current literature as 'wild dogma'.In this short supplement,we briefly highlight the roles and implications of wild dogma for wild dog management in Australia.We discuss nomenclature,and the influence that unreliable science can have on policy and practice changes related to apex predator management [Current Zoology 57 (6):737-740,2011].

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

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

    2015-12-01

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

    To assist in the development of the 2008 Australian/New Zealand standard on solaria and related regulations, Australian Radiation Protection and Nuclear Safety Agency scientists visited a number of tanning establishments during 2008 to measure the intensity and spectral distribution of the ultraviolet radiation (UVR) emissions from a range of solaria. The 2002 Australian/New Zealand Standard "Solaria for cosmetic purposes" (AS/NZS 2635) allowed a maximum UVR output from solaria of UV Index 60, a compromise between the solarium industry who wanted no upper limit and the health agencies who wanted to limit intensity. Of the 20 solaria examined in detail, only one had emissions of intensity less than UV Index 12, typical of mid-latitude summer sunlight, 15 units emitted more than UV Index 20, while three units emitted at intensities above UV Index 36, the maximum allowed by the new standard, AS/NZS 2635 (2008) and would thus not comply. UVA emissions ranged from 98W·m(-2) up to a maximum of 438W·m(-2) , more than six times the UVA content of mid-latitude summer sunshine. The results indicate that solaria users in Australia have access to solaria that are high intensity units with both significantly higher UVB and UVA emissions than sunlight, with implications for resultant adverse health effects.

  14. The long term sustainability of Mound Springs in South Australia : implications for olympic dam

    International Nuclear Information System (INIS)

    The Mound Springs of South Australia are unique groundwater discharge features of the Great Artesian Basin, a deep regigonal groundwater system that covers over one-fifth of the Australia continent. They are the principal sources of water in the arid and semi-arid inland heart of Australia, and have great ecological, scientific, anthropological and economic significance. Excessive development of the Great Artesian Basin over the past century by European activity has seen an overall decline in the flows from the mound springs, and recent development of the water supply borefields for the WMC Olympic Dam Operations copper-uranium mine in the midst of the most important spring groups has exacerbated this problem. A review of the history of the borefields, an analysis of the impacts on the mound springs, and future recommendations for protection of the springs is presented. (orig.)

  15. CO2 embodiment in China–Australia trade: The drivers and implications

    International Nuclear Information System (INIS)

    This study focuses on CO2 emissions ‘embodied’ in the characteristic China–Australia bilateral trade, which refer to the CO2 emissions due to the production of goods traded between the two countries. We perform an assessment of the CO2 embodiment in the trade during the period between 2002 and 2010. We find that the scale effect has been a dominant effect contributing to an increase of CO2 emissions embodied in the bilateral trade through the years; while the composition effect seems to be a major driver for reducing CO2 embodiment in the exports of Australia to China. Based on an analysis of the difference between the amounts of actual CO2 embodiment and those in a hypothetical ‘no-trade’ scenario, we estimate that the ‘net’ CO2 emissions due to the bilateral trade declined from around 10 Mt of CO2 emissions in 2002 to −10 Mt in 2010; that is, the bilateral trade contributed to a reduction of the global carbon emissions in the recent years. This finding suggests that the rapid growth of exports of carbon-intensive goods from Australia to China has helped in reducing carbon emissions globally because carbon intensity factors of those goods are much lower in Australia than those in China. - Highlights: • This research focuses on CO2 emissions embodied in China–Australia trade. • Australia is mainly a resource provider while China exports manufacturing goods. • The scale effect is a dominant effect for increasing the CO2 embodiments. • The composition effect is a major driver for reducing the CO2 embodiments. • The trade contributed to a reduction of the global carbon emissions in 2010

    The temporal variations during 1948-2010 and vertical structures of the summer Somali and Australia cross-equatorial flows (CEFs) and the implications for the Asian summer monsoon were explored in this study.The strongest southerly and northerly CEFs exist at 925 hPa and 150 hPa level,respectively.The low-level Somali (LLS) CEFs were significantly connected with the rainfall in most regions of India (especially the monsoon regions),except in a small area in southwest India.In comparison to the climatology,the lowlevel Australia (LLA) CEFs exhibited stronger variations at interannual time scale and are more closely connected to the East Asian summer monsoon circulation than to the LLS CEFs.The East Asian summer monsoon circulation anomalies related to stronger LLA CEFs were associated with less water vapor content and less rainfall in the region between the middle Yellow River and Yangtze River and with more water vapor and more rainfall in southern China.The sea-surface temperature anomalies east of Australia related to summer LLA CEFs emerge in spring and persist into summer,with implications for the seasonal prediction of summer rainfall in East Asia.The connection between the LLA CEFs and East Asian summer monsoon rainfall may be partly due to its linkage with El Nino-Southern Oscillation.In addition,both the LLA and LLS CEFs exhibited interdecadal shifts in the late 1970s and the late 1990s,consistent with the phase shifts of Pacific Decadal Oscillation (PDO).

    2015-01-01

    The aim of this article is to review the Australian literature about suicidality in minority sexual identity and/or behavior groups in order to determine the evidence base for their reported higher vulnerability to suicidal behaviors than heterosexual and non-transgendered individuals in the Australian context, as well as to identify the factors that are predictive of suicidal behaviors in these groups in Australia. A literature search for all available years (until the end of 2012) was conducted using the databases Scopus, Medline, and Proquest for articles published in English in peer-reviewed academic journals. All peer-reviewed publications that provided empirical evidence for prevalence and predictive factors of suicidal behaviors among LGBT individuals (or a subset thereof) in Australia were included. Reference lists were also scrutinized to identify "gray" literature for inclusion. The results revealed that there is only limited research from Australia. Nevertheless, although no population-based studies have been published, research indicates that sexual minorities are indeed at a higher risk for suicidal behaviors. In order to further the understanding of suicidal behaviors and potential prevention among LGBT groups in the Australia, further research is needed, particularly on fatal suicidal behaviors.

  2. Fifty years of changes in UV Index and implications for skin cancer in Australia

    Lemus-Deschamps, Lilia; Makin, Jennifer K.

    2012-07-01

    Surface ultraviolet (UV) radiation plays an important role in human health. Increased exposure to UV radiation increases the risk of skin cancer. In Australia, public campaigns to prevent skin cancer include the promotion of daily UV forecasts. If all other atmospheric factors are equal, stratospheric ozone decreases result in UV increases. Given that Australia still has the highest skin cancer rates in the world, it is important to monitor Australia's stratospheric ozone and UV radiation levels over time because of the effects cumulative exposure can have on humans. In this paper, two long-term ozone datasets derived from surface and satellite measurements, a radiation code and atmospheric meteorological fields are used to calculate clear-sky UV radiation over a 50-year period (1959-2009) for Australia. The deviations from 1970-1980 levels show that clear-sky UV is on the rise. After the 1990s, an overall annual increase from 2 to 6% above the 1970-1980 levels was observed at all latitudes. Examining the summer and winter deviations from 1970-1980 showed that the winter signal dominated the annual changes, with winter increases almost twice those in summer. With ozone levels not expected to recover to pre-depletion levels until the middle of this century, UV levels are expected to continue to rise. Combined with Australians favoring an outdoor life-style, when temperatures are warmer, under high levels of UV, the associated risk of skin cancer will increase.

    Hibiscus tridactylites is a problematic broadleaf weed in many crops in Australia; however, very limited information is available on seed germination biology of Australian populations. Experiments were conducted to evaluate the effect of environmental factors on germination and emergence of H. tridactylites. Germination was stimulated by seed scarification, suggesting the inhibition of germination in this species is mainly due to the hard seed coat. Germination was not affected by light condi...

    Background: Australia has a hot climate with maximum summer temperatures in its major cities frequently exceeding 35°C. Although ‘heat waves’ are an annual occurrence, the associated heat-related deaths among vulnerable groups, such as older people, suggest that Australians could be better prepared to deal with extreme heat.Objective: To understand ways in which a vulnerable sub-population adapt their personal behaviour to cope with heat within the context of Australians’ relationship with he...

    A pot culture experiment was used to determine the differences in uptake characteristics of a cadmium hyperaccumulator Solanum nigrum L. discovered in China, an ecotype from Melbourne, Australia and a non-hyperaccumulator Solanum melogena Australian ecotype was not significantly different to the China ecotype. In particular, Cd concentration in leaves and shoots of S. nigrum collected from Australia were 166.0 and 146.3 mg kg(-1) respectively when 20 mg kg(-1) Cd spiked, and were not significantly different to the ecotype imported from China which had 109.8 and 85.3 mg kg(-1) respectively, in the stems and leaves. In contrast, the tolerance of the eggplant to Cd was significantly less than the two S. nigrum ecotypes. Although some morphological properties of S. nigrum collected from Australia were different from that of the plants collected from China, Cd hyperaccumulator characteristics of two ecotypes were similar. The results suggested that the tolerance and uptake of Cd may be a constitutive trait of this species. PMID:23488006

    Davies, Peter J; Gore, Damian B; Khan, Stuart J

    2015-07-01

    This paper reviews the environmental problems, impacts and risks associated with the generation and disposal of produced water by the emerging coal seam gas (CSG) industry and how it may be relevant to Australia and similar physical settings. With only limited independent research on the potential environmental impacts of produced water, is it necessary for industry and government policy makers and regulators to draw upon the experiences of related endeavours such as mining and groundwater extraction accepting that the conclusions may not always be directly transferrable. CSG is widely touted in Australia as having the potential to provide significant economic and energy security benefits, yet the environmental and health policies and the planning and regulatory setting are yet to mature and are continuing to evolve amidst ongoing social and environmental concerns and political indecision. In this review, produced water has been defined as water that is brought to the land surface during the process of recovering methane gas from coal seams and includes water sourced from CSG wells as well as flowback water associated with drilling, hydraulic fracturing and gas extraction. A brief overview of produced water generation, its characteristics and environmental issues is provided. A review of past lessons and identification of potential risks, including disposal options, is included to assist in planning and management of this industry. PMID:25783163

  11. Urban Flood Damage and Greenhouse Scenarios. The Implications for Policy. An Example from Australia

    International Nuclear Information System (INIS)

    Urban flooding is often used as an illustration of the potentially adverse effects of greenhouse-induced climate change on extreme events. There is however, a paucity of studies that convert climate scenarios into changes in flood damage. This account summarises the use of modelling techniques, for three flood prone urban catchments in south eastern Australia, to assess changes to urban flood losses for the 'most wet' and ,most dry' scenarios for the year 2070. The most wet scenario indicates that annual average flood damage could increase within the range of 2.5 to 10 times, under the most dry scenario flood regimes would be similar to those experienced at present. The socio-economic scenarios based on the changes to flood losses are used to consider policy responses. It is unlikely that many local government authorities will respond because of lack of interest and because of major changes to the climate scenarios proposed over the last decade. Any response is likely to be incremental and accord with the 'no regrets' and 'the precautionary principle'. 21 refs

  12. Environmental implications of offshore oil and gas development in Australia. Part 3; Drilling activities

    International Nuclear Information System (INIS)

    This report on the environmental effects of offshore drilling activities comprises a review of published literature on the subject, mostly from overseas though some with particular reference to Australia, and reports made available by offshore operators. Australian operators drill between 50 and 100 offshore wells per year, of which about 25 per cent are development wells on multi-well platforms where environmental effects can be more concentrated. The major potential environmental effects from offshore drilling operations result from the discharge of wastes, including drilling fluids and drill cuttings. Of these effects, burial and substrate modification caused by sedimentation within a few hundred metres of the well are the most important. Discharges of drilling wastes generally have been shown to have only minor effects on water quality and pelagic ecosystems. These effects are more severe where oil-based fluids are used. Many drilling fluid constituents or impurities are known to be toxic to marine organisms at very high concentrations, which are typically quantified as the 96-hr LC50 value, being the concentration at which 50 per cent of the test population dies after 96 hours of exposure. In the field such concentrations would only be found in the water column for short times after a discharge and within a few tens of metres from point of discharge, and on the sea bed typically less than 100 m from the discharge point for a single well, and up to 400 m from a multi-well platform. 430 refs., 18 tabs., 8 figs

    2016-01-01

    Hibiscus tridactylites is a problematic broadleaf weed in many crops in Australia; however, very limited information is available on seed germination biology of Australian populations. Experiments were conducted to evaluate the effect of environmental factors on germination and emergence of H. tridactylites. Germination was stimulated by seed scarification, suggesting the inhibition of germination in this species is mainly due to the hard seed coat. Germination was not affected by light conditions, suggesting that seeds of this species are not photoblastic. Germination was higher at alternating day/night temperatures of 30/20 °C (74%) and 35/25 °C (69%) than at 25/15 °C (63%). Moderate salinity and water stress did not inhibit germination of H. tridactylites. Seedling emergence of H. tridactylites was highest (57%) for the seeds buried at a 2 cm depth in the soil; 18% of seedlings emerged from seeds buried at 8 cm but no seedlings emerged below this depth. Soil inversion by tillage to bury weed seeds below their maximum depth of emergence could serve an important tool for managing H. tridactylites. PMID:27174752

    The Cooper Basin is located in centre part of the Australian continent, 5000km away from the nearest plate boundary. This Late Carboniferous to Middle Triassic basin is the largest onshore sedimentary basin producing oil and gas in Australia - mostly by fraccing tight reservoirs. Thus, an extensive database is available for studying the in-situ stress field in the basin. Previous studies have shown a significant variability if the stress field across the basin. However, the development of the mostly tight prospects require a good understanding of the structure of the reservoirs, mechanical properties of the stratigraphy, fracture geometry and density, in-situ stress field and fracture stimulation strategies in order to maximise the production This study provides new in-situ stress data from borehole breakouts and drilling-induced tensile fractures, along with a description of the fractures present along the well trajectory. The geometry of the natural fault and fracture network is interpreted from 3D seismic data, and compared to the well data. Finally, we performed a series of numeric simulation to test the fault and fracture stability in the present-day stress field. These data and our interpretation are used to evaluate the geomechanical properties of the Cooper Basin. This method is reproducible to other oil-bearing basins around the world, but is also applicable to the development of engineered geothermal reservoir or evaluation of carbon dioxide storage site.

    2011-09-01

    Full Text Available Objectives: This study aimed to explore how well Victorian pharmacists perceived they understood pharmacogenetics, their perceived capacity to counsel a patient about such testing, how they believed pharmacogenetics would impact upon their profession, and to investigate the ways in which Victorian pharmacists would like to be educated about pharmacogenetics.Methods: A cross-sectional survey was dispatched to 800 Victorian pharmacists. The participants were randomly selected and the survey was anonymous. The survey contained questions about where the pharmacists worked, the pharmacists’ perceived knowledge of pharmacogenetics, how well they believed they would be able to counsel patients about pharmacogenetic testing, how they thought pharmacists should be educated on the topic and how they believed pharmacogenetics would impact upon their profession.Results: 291 surveys were returned (36% response rate. Results suggest that Victorian pharmacists generally perceived they had a poor understanding of pharmacogenetics and that those who have more recently graduated from tertiary education had a better perceived understanding than those who have been in the workforce for longer. Most pharmacists indicated that they did not believe that they could counsel a patient adequately about the results of a pharmacogenetic test. Regarding education about pharmacogenetics, participants suggested that this would be best delivered during tertiary studies, and as seminars and workshops forming part of their continuing professional development. Although some pharmacists were unsure how pharmacogenetics would affect their profession, many believed it would have a major impact upon their role as a pharmacist and lead to improved patient care. Some concerns about the implementation of pharmacogenetics were noted, including economic and ethical issues.Conclusion: This study highlights the need for further research across the pharmacy profession in Australia on the

  19. Environmental implications of offshore oil and gas development in Australia. The finding of an independent scientific review

    International Nuclear Information System (INIS)

    It is widely recognised that uncontrolled discharge of petroleum products or other materials from offshore oil and gas exploration and production wells, and from associated industrial operations including treatment and service facilities that are required to be on or near the coast, can have direct and sometimes deleterious impacts on the marine environment. In mid-1992, the Australian Petroleum Exploration Association (APEA) commissioned five scientific reviews to examine the environmental implications of offshore petroleum developments in Australia. The reviews, carried out by an Independent Scientific Review Committee on behalf of the Australian Petroleum Exploration Association (APEA) and the Energy Research and Development Corporation (ERDC) deal with: (1) the preliminary geophysical exploration of the sea bed and underlying strata using seismic surveys, and especially the effects of bursts of underwater sound energy on biological communities; (2) the drilling of offshore wells, especially the disposal of drilling fluids and drill cuttings; (3) the production of oil and gas from proven wells, especially the disposal of large quantities of produced formation water (fossil water); (4) the construction and operation of coastal support facilities and associated activities which might have consequences for marine habitats; (5) oil spills associated with any of the above operations and especially the likely short- and long-term effects of an accidental oil spill on marine biota and on the aesthetic and commercial values of an impacted coastline. Comments on the findings are preceded by a brief summary of background information, relevant technologies and the main implications for the marine environment. Some suggestions are provided for possible future research, monitoring and environmental management. refs., figs., tabs

  20. Long-term spatio-temporal precipitation variability in arid-zone Australia and implications for groundwater recharge

    2016-01-01

    Quantifying dryland groundwater recharge as a function of climate variability is becoming increasingly important in the face of a globally depleted resource, yet this remains a major challenge due to lack of adequate monitoring and the complexity of processes involved. A previously unpublished and unique dataset of high density and frequency rainfall measurements is presented, from the Fowlers Gap Arid Zone Research Station in western New South Wales (Australia). The dataset confirms extreme spatial and temporal variability in rainfall distribution which has been observed in other dryland areas and is generally explained by the dominance of individual storm cells. Contrary to previous observations, however, this dataset contains only a few localised storm cells despite the variability. The implications of spatiotemporal rainfall variability on the estimation of groundwater recharge is assessed and show that the most likely recharge mechanism is through indirect and localised, rather than direct, recharge. Examples of rainfall and stream gauge height illustrate runoff generation when a spatially averaged threshold of 15-25 mm (depending on the antecedent moisture conditions) is exceeded. Preliminary assessment of groundwater levels illustrates that the regional water table is much deeper than anticipated, especially considering the expected magnitude of indirect and localised recharge. A possible explanation is that pathways for indirect and localised recharge are inhibited by the large quantities of Aeolian dust observed at the site. Runoff readily occurs with water collecting in surface lakes which slowly dry and disappear. Assuming direct groundwater recharge under these conditions will significantly overestimate actual recharge.

  1. Links between the Big Dry in Australia and hemispheric multi-decadal climate variability - implications for water resource management

    Science.gov (United States)

    2014-06-01

    Southeast Australia (SEA) experienced a protracted drought during the mid-1990s until early 2010 (known as the Big Dry or Millennium Drought) that resulted in serious environmental, social and economic effects. This paper analyses a range of historical climate data sets to place the recent drought into context in terms of Southern Hemisphere inter-annual to multi-decadal hydroclimatic variability. The findings indicate that the recent Big Dry in SEA is in fact linked to the widespread Southern Hemisphere climate shift towards drier conditions that began in the mid-1970s. However, it is shown that this link is masked because the large-scale climate drivers responsible for drying in other regions of the mid-latitudes since the mid-1970s did not have the same effect on SEA during the mid- to late 1980s and early 1990s. More specifically, smaller-scale synoptic processes resulted in elevated autumn and winter rainfall (a crucial period for SEA hydrology) during the mid- to late 1980s and early 1990s, which punctuated the longer-term drying. From the mid-1990s to 2010 the frequency of the synoptic processes associated with elevated autumn/winter rainfall decreased, resulting in a return to drier than average conditions and the onset of the Big Dry. The findings presented in this paper have marked implications for water management and climate attribution studies in SEA, in particular for understanding and dealing with "baseline" (i.e. current) hydroclimatic risks.

  2. Effect of spatial variation on salinity tolerance of macroinvertebrates in Eastern Australia and implications for ecosystem protection trigger values

    International Nuclear Information System (INIS)

    Salinisation of freshwater has been identified as a serious environmental issue in Australia and around the world. Protective concentrations (trigger values) for salinity can be used to manage salinity impacts, though require locally relevant salinity tolerance information. 72-h acute salinity tolerance values were determined for 102 macroinvertebrates collected from 11 locations in four biologically distinct freshwater bio-regions in Northeast Australia and compared with sensitivities observed in Southeast Australia. The salinity tolerance of individual taxa was consistent across Northeast Australia and between Northeast and Southeast Australia. However, two distinct communities were identified in Northeast Australia using distributions of the acute tolerance values and a calculated index of salinity sensitivity. Salinity trigger values should therefore be representative of local or regionally relevant communities and may be adequately calculated using sensitivity values from throughout Eastern Australia. The results presented provide a basis for assessing salinity risk and determining trigger values for salinity in freshwater ecosystems at local and regional scales in Eastern Australia. - Salinity tolerance of macroinvertebrate communities vary in Eastern Australia hence water quality guidelines should be developed at a local or regional scale

  4. Potential impacts of global warming on Australia's unique tropical biodiversity and implications for tropical biodiversity in general

    International Nuclear Information System (INIS)

    Full text: Full text: Globally, forest clearing is often thought to be the greatest threat to biodiversity in the tropics, and rates of clearing are certainly highest there, particularly in tropical South-East Asia. Climate change in the tropics has been less studied in tropical regions than in temperate, boreal or arctic ecosystems. However, modelling studies in Australian rainforests indicate that climate change may be a particularly significant threat to the long-term preservation of the biodiversity of tropical, rainforest biodiversity. Our research has shown that global warming can have a particularly strong impact on the biodiversity of mountainous tropical regions, including the Wet Tropics of north-east Queensland. Here, the mountain tops and higher tablelands are relatively cool islands in a sea of warmer climates. These species-rich islands, mostly limited in their biodiversity by warm interglacial periods, are separated from each other by the warmer valleys and form a scattered archipelago of habitat for organisms that are unable to survive and reproduce in warmer climates. Many of the endemic Australian Wet Tropics species live only in these cooler regions. Similar situations occur throughout south-east Asia and in the highlands of the Neotropics. Unfortunately, these upland and highland areas represent the majority of biodiversity conservation areas because they are less suitable for clearing for agriculture. This presentation will summarise research about the potential impacts of climate change on the biodiversity in Australia's rainforests, the potential implications for tropical biodiversity in general and discuss the limitations of these projections and the need for further research that could reduce uncertainties and inform effective adaptation strategies

  5. Geochemistry and petrogenesis of mafic-ultramafic suites of the Irindina Province, Northern Territory, Australia: Implications for the Neoproterozoic to Devonian evolution of central Australia

    2015-10-01

    Petrological and geochemical data for magmatic mafic-ultramafic suites of the Irindina and Aileron provinces of the Eastern Arunta region, Northern Territory, Australia constrain the petrogenesis and tectonic setting of magmatic events covering ~ 500 million years. Six geochemically distinct magmatic suites, here named A-F, have been identified and provide evidence of the tectonic history of this region and also are linked to two mineralisation-related magmatic events: the Lloyd Gabbro (Ni-Cu-PGE mineralisation) and the Riddoch Amphibolite (Cyprus-style Cu-Co volcanogenic massive sulphide mineralisation). The whole-rock geochemistry of Suites A and F is indicative of melts derived from a range of mantle depths (garnet to spinel lherzolite) and source enrichment. Suite D is likely related to the ~ 1070 Ma Warakurna/Giles event of central Australia, including the Alcurra (Musgrave) and Stuart (Arunta) dyke swarms, and likely formed through either: a) melting of subduction modified, sub-continental lithospheric mantle (SCLM) by an upwelling mantle plume; or b) a combination of intra-plate tectonic processes involving a long-lived thermal anomaly, lithospheric-scale architecture that focussed magmatism, and large-scale tectonism. Suite F represents more alkaline magmas, derived from a deeper source, but most likely formed during the same Warakurna LIP event (possibly contemporaneously) as Suite D. Suite E (the Riddoch Amphibolite) was most likely emplaced in a back-arc basin (BAB) setting at ~ 600 Ma, coincident with Delamerian subduction and BAB formation along the eastern Proterozoic margin of Australia from Queensland to the eastern Arunta and possibly further south. Subsequent destabilisation of the SCLM underneath the North Australian Craton generated the ~ 510 Ma Kalkarindji LIP in the form of Suite B intrusions that assimilated some of the older Suite E (Riddoch) material. This event is locally known as the ~ 506 Ma Stanovos Igneous Suite and represents the most

    Rice is an important route of arsenic (As) exposure to humans, especially populations with rice-based diets. Human health risk of As varies greatly with rice variety and country of origin. The purpose of the present study was to determine total and speciated As in Australian-grown and imported rice on sale in Australia to assess their health risk to consumers. The total As (tAs) concentrations in Australian-grown organic brown, medium grain brown, and organic white rice were 438±23, 287±03, and 283±18 μg kg(-1) dry weight (d wt), respectively. In Bangladeshi, Indian, Pakistani, and Thai rice imported and on sale in Australia, tAs concentrations were 56±05, 92±10, 82±06 and 172±24 μg kg(-1), respectively. Asian rice contained mainly inorganic As (iAs; 86-99%), whereas 18-26% of the tAs in Australian-grown rice was dimethylarsinic acid (DMA). Relatively higher concentrations of tAs in Australian-grown rice than that in imported rice of Asian origin suggest that Australian-grown rice may be a health risk for the consumers. It was estimated that Australian-grown organic brown rice can contribute up to 98% of the FAO/WHO recommended maximum tolerable daily intake limit of iAs (2.1 μg kg(-1) body wt day(-1)) for Asian immigrants. However, other Australian consumers including European immigrants are unlikely to be at risk to As from rice diets due to their lower rice consumption rates than that of Asian immigrants. The risk assessment showed that imported rice on sale in Australia was likely to pose a lower health risk to consumers than Australian-grown rice. PMID:24892387

  14. Chronostatigraphic basin framework for Palaeoproterozoic rocks (1730-1575 Ma) in northern Australia and implications of base-metal mineralisation

    International Nuclear Information System (INIS)

    The new chronostratigraphic subdivision for Palaeoproterozoic rocks of northern Australia provides an improved framework for future resource exploration. The nine supersequence boundaries identified in the ca 1730-1575Ma Calvert and Isa Superbasins enable the timing of major tectonic events and their stratigraphic response to be better understood. Third- and 4th-order sequence boundaries facilitate the determination of stratigraphic architecture, ultimately providing the necessary information for constraining the flow of fluids in these basins. SHRIMP zircon ages are essential for determining the magnitude of depositional hiatuses at supersequence and some sequence boundaries, and together with palaeomagnetic data provide independent age constraints for the sequence interpretations. Pb/Pb model ages for the world class Broken Hill, Mt Isa, McArthur River and Century Zn Pb Ag deposits coincide with tectonic events recorded at the Gun, Loretta, River Supersequence boundaries and the superbasin boundary formed during closure of the Isa Superbasin during D2 at Mt Isa. The coincidence of a Pb/Pb model age for Broken Hill with an apparent polar wander path inflection at the Gun Supersequence boundary indicates that the regional chronostratigraphic basin framework developed for northern Australia is applicable to rocks of similar age elsewhere in Australia. Furthermore, if the ultimate cause of these inflections is interplate stress, the basin framework should be globally applicable. Hand-held spectrometers provide an efficient and cost-effective method for collecting gamma-ray data from outcrops. The resulting gamma-ray curves permit more accurate correlation with subsurface stratigraphies and together with facies information facilitate the identification of stratigraphic sequences and their bounding stratal surfaces, the essential building blocks of regional chronostratigraphic correlations. Contrary to general belief most of the sections measured in this study preserve

    The Tasmanides of eastern Australia record much of the Phanerozoic tectonic development of the retreating Pacific-Australia plate boundary and are an oft-cited example of an orogen that has undergone "tectonic mode switching." To begin to constrain the timing of exhumation of basement rocks that are now exposed in portions of the NE Tasmanides, we measured apatite and zircon (U-Th)/He ages from the Thomson Orogen and overlying Paleozoic strata in the back-arc of the New England Orogen in NE Australia. Zircon (U-Th)/He ages from basement samples (including those recovered from boreholes at depths of up to 1.1 km) are characterized by large inter- and intra-sample variability and range from approximately 180 Ma (Early Jurassic) to 375 Ma (Late Devonian). (U-Th)/He zircon ages from several individual samples are negatively correlated with effective uranium (eU), a pattern that is also true of the dataset as a whole, suggesting that variations in U and Th zoning and radiation damage are partially responsible for the age variability. The oldest zircon (U-Th)/He cooling ages coincide with the formation of regionally extensive Late Devonian-early Carboniferous back-arc basins, suggesting that Late Devonian extension played a significant role in exhumation of parts of the northern Thomson Orogen. Apatite (U-Th)/He ages from a basement sample and a late Permian sandstone in the overlying Bowen Basin, which are also marked by intra-sample variability and age-eU correlations, span from the Early Cretaceous through Oligocene, in general agreement with previous apatite fission track data. In conjunction with observations of key geologic relationships and prior K-Ar and 40Ar/39Ar data, our results suggest four overall phases in the thermal history of the northern Thomson Orogen: (1) Cambrian-early Silurian metamorphism during the Delamerian and Benambran Orogenies; (2) protracted cooling during the Late Devonian through mid-Permian that likely resulted from extensional

    This study examines the patterns of depositional variability, sediment geochemistry and metal distribution in intertidal areas of Moreton Bay, southeast Queensland, Australia. Recent concern over increasing human impact on the bay has generated the need to obtain evidence on how the disturbance of the depositional setting might affect the natural estuarine environment. Sediment stratigraphy, major, and trace element analyses of sediment cores show that the sedimentation pattern is unique to each intertidal site. Disturbed 210Pb and 137Cs activity profiles of some of the cores indicate that sediment reworking occurs across the intertidal flats up to a depth of at least 80 cm. With some notable exceptions, an accurate geochronology of the surface sediments could not be established due to low 210Pb activities and sediment mixing. Thus, an increase in Pb, Zn and Cu towards the surface sediments observed at various sites is attributed to both anthropogenic contribution following the rapid urban development in the last century and to post-depositional diagenetic processes, bioturbation and sediment re-suspension induced by tides, storms or floods. Sediment cores are representative only of the local sedimentation and may not always allow extensive correlation to larger areas. Vertical profiles of heavy metals reflect the different depositional environment controlled by the complex hydrodynamics of the bay. Local hydrologic, physical, and tidal conditions might induce metals redistribution at different scales. This information is of critical importance in view of sediment remobilization caused by future development such as dredging, intertidal areas reclamation or excavation of new navigational channels.

    / Geomorphologically derived river styles provide an integrative framework for examining the interactions of biophysical processes in rivers throughout a drainage basin. Nine styles of river character and behavior are identified in Bega catchment, on the south coast of New South Wales, Australia. Headwater streams above the escarpment drain into gorges in the escarpment zone. In different subcatchments at the base of the escarpment, there are three different river styles, namely cut-and-fill, vertically accreted floodplains, and fans. Downstream of these river styles, in the rounded foothills of the catchment, throughput and transfer river styles convey sediments to the lowland plain. In one mid-catchment setting, a floodout traps sediment. Finally, along the lowland plain of Bega River, there is a floodplain accumulation river style. Downstream patterns of river styles in differing subcatchments of the Bega River basin are differentiated into three types, reflecting river adjustments to valley width, slope, and responses to human disturbance. Analysis of the character and condition of each river style in Bega catchment, and their downstream patterns, are used to provide a biophysical basis to prioritorize river management strategies. These reach-scale strategies are prioritorized within an integrative catchment framework. Conserving near-intact sections of the catchment is the first priority. Second, those parts of the catchment that have natural recovery potential are targeted. Finally, rehabilitation priorities are considered for highly degraded reaches. At these sites, erosion and sedimentation problems may reflect irreversible changes to river structure. PMID:10790530

    The Paleozoic to early Mesozoic southern New England Orogen of eastern Australia exhibits a remarkable ear-shaped curvature (orocline), but the geodynamic processes responsible for its formation are unclear. Oroclinal bending took place during the early Permian, simultaneously with the deposition of the rift-related Sydney, Gunnedah, and Bowen basins, which bound the oroclines to the west. The Nambucca Block is another early Permian rift basin, but it is situated in the core of the oroclinal structure. Here we present new stratigraphic, structural, and geochronological data from the Nambucca Block in an attempt to better understand its tectonic history and relationships to the formation of the oroclines. We recognized four phases of folding and associated structural fabrics (S1-4), with the second phase (S2) dated at 275-265 Ma by 40Ar/39Ar geochronology of muscovite. This age overlaps with independent constraints on the timing of oroclinal bending, suggesting that the earlier two phases of deformation in the Nambucca Block (F1 and F2) were associated with orocline formation. We propose that oroclinal bending involved three major stages. The first stage (basins in a hot extensional back-arc setting. This was followed by a second stage of oroclinal bending, possibly linked to dextral wrench faulting, which involved ~ N-S contraction (F1). Subsequent deformation at 275-265 Ma involved formation of nappe-style structures (F2). This phase of contractional deformation may have resulted from an increased plate coupling that was possibly linked to flat-slab subduction.

    New geochemical, metamorphic, and isotopic data are presented from high-pressure metamorphic rocks in the southern New England Orogen (eastern Australia). Conventional and optimal thermobarometry are augmented by U-Pb zircon and 40Ar/39Ar phengite dating to define pressure-temperature-time (P-T-t) histories for the rocks. The P-T-t histories are compared with competing geodynamic models for the Tasmanides, which can be summarized as (i) a retreating orogen model, the Tasmanides formed above a continuous, west dipping, and eastward retreating subduction zone, and (ii) a punctuated orogen model, the Tasmanides formed by several arc accretion, subduction flip, and/or transference events. Whereas both scenarios are potentially supported by the new data, an overlap between the timing of metamorphic recrystallization and key stages of Tasmanides evolution favors a relationship between a single, long-lived subduction zone and the formation, exhumation, and exposure of the high-pressure rocks. By comparison with the retreating orogen model, the following links with the P-T-t histories emerge: (i) exhumation and underplating of oceanic eclogite during the Delamerian Orogeny, (ii) recrystallization of underplated and exhuming high-pressure rocks at amphibolite facies conditions coeval with a period of rollback, and (iii) selective recrystallization of high-pressure rocks at blueschist facies conditions, reflecting metamorphism in a cooled subduction zone. The retreating orogen model can also account for the anomalous location of the Cambrian-Ordovician high-pressure rocks in the Devonian-Carboniferous New England Orogen, where sequential rollback cycles detached and translated parts of the leading edge of the overriding plate to the next, younger orogenic cycle.

    The Murray dairy region produces approximately 1.85 billion litres of milk each year, representing about 20 % of Australia's total annual milk production. An ongoing production challenge in this region is the management of the impacts of heat stress during spring and summer. An increase in the frequency and severity of extreme temperature events due to climate change may result in additional heat stress and production losses. This paper assesses the changing nature of heat stress now, and into the future, using historical data and climate change projections for the region using the temperature humidity index (THI). Projected temperature and relative humidity changes from two global climate models (GCMs), CSIRO MK3.5 and CCR-MIROC-H, have been used to calculate THI values for 2025 and 2050, and summarized as mean occurrence of, and mean length of consecutive high heat stress periods. The future climate scenarios explored show that by 2025 an additional 12-15 days (compared to 1971 to 2000 baseline data) of moderate to severe heat stress are likely across much of the study region. By 2050, larger increases in severity and occurrence of heat stress are likely (i.e. an additional 31-42 moderate to severe heat stress days compared with baseline data). This increasing trend will have a negative impact on milk production among dairy cattle in the region. The results from this study provide useful insights on the trends in THI in the region. Dairy farmers and the dairy industry could use these results to devise and prioritise adaptation options to deal with projected increases in heat stress frequency and severity.

    While coral reefs in many parts of the world are in decline as a direct consequence of human pressures, Australia's Great Barrier Reef (GBR) is unusual in that direct human pressures are low and the entire system of ~2,900 reefs has been managed as a marine park since the 1980s. In spite of these advantages, standard annual surveys of a large number of reefs showed that from 1986 to 2004, average live coral cover across the GBR declined from 28 to 22%. This overall decline was mainly due to large losses in six (21%) of 29 subregions. Declines in live coral cover on reefs in two inshore subregions coincided with thermal bleaching in 1998, while declines in four mid-self subregions were due to outbreaks of predatory starfish. Otherwise, living coral cover increased in one subregion (3%) and 22 subregions (76%) showed no substantial change. Reefs in the great majority of subregions showed cycles of decline and recovery over the survey period, but with little synchrony among subregions. Two previous studies examined long-term changes in live coral cover on GBR reefs using meta-analyses including historical data from before the mid-1980s. Both found greater rates of loss of coral and recorded a marked decrease in living coral cover on the GBR in 1986, coinciding exactly with the start of large-scale monitoring. We argue that much of the apparent long-term decrease results from combining data from selective, sparse, small-scale studies before 1986 with data from both small-scale studies and large-scale monitoring surveys after that date. The GBR has clearly been changed by human activities and live coral cover has declined overall, but losses of coral in the past 40-50 years have probably been overestimated.

    We present the first transect measurements of CH4, CO2, CO and N2O taken on the Ghan railway travelling on a N-S transect of the Australian continent between Adelaide (34.9°S, 138.6°E) and Darwin (12.5°S, 130.9°E). The Ghan crosses Australia from the mainly agricultural mid-latitude south through the arid interior to the wet-dry tropical savannah south of and around Darwin. In the 2008 wet season (February) we observed a significant latitudinal gradient of CH4 increasing towards the north. The same pattern was observed in the late 2008 wet season (March-April), with a smaller latitudinal gradient. These will be compared with a dry season transect, to be undertaken in September/October 2008. The Air Pollution Model (TAPM), a regional scale prognostic meteorological model, is used to estimate the surface methane source strength required to explain the observed latitudinal gradient in CH4 in the wet season, and investigate the source type. Fluxes from cattle and termites together contribute up to 25% of the enhancements seen, leaving wetlands as the major source of wet season methane in the Australian tropics. Wetlands are the largest natural source of methane to the atmosphere, and tropical wetlands are responsible for the majority of the interannual variation in methane source strength. We attempt to quantify the annual methane flux contributed by anaerobic organic breakdown due to wet- season flooding in tropical Northern Territory.

    Only few geomorphological studies on the Canning Coast of Western Australia exist to date, most probably reflecting its remoteness and low population density. However, WA's annual gross state product (GSP) growth of ~5 % during the past decade and the highest GSP per capita nationwide resulting from a mining boom increase public attention as well as the demand for precise information on landscape inventory and evolution. In this paper, new data from a sequence of vegetated foredune barriers, gradually being eroded by a migrating estuary inside the macrotidal Admiral Bay (also known as McKelson Creek, Whistle Creek or Panganunganyjal), 110 km southwest of Broome, are presented. Based on sediment cores, DGPS-based elevation transects, and stratigraphical analyses on outcrops of the relict foredunes, we aim at (i) reconstructing lateral coastal changes during the Holocene, (ii) drawing inferences on relative sea-level (RSL) change, and (iii) identifying and dating imprints of extreme-wave events. Sedimentary analyses comprise documentation of bedding structures, foraminiferal content and macrofaunal remains (including shell taphonomy), grain size, and organic matter. Chronological contexts are established using 26 14C-AMS datings. Marine flooding of the pre-Holocene base landward of the 2.5 km-wide foredunes can be pinpointed to 7400-7200 cal BP. A mangrove ecosystem established and was quickly replaced by intertidal coarse sands after only 200-400 years. The high-energy intertidal environment prevailed until c. 4000 cal BP before turning into the present supralittoral mudflat environment. At that time, coastal regression led to beach progradation and isochronic formation of foredune barriers. Drivers of progradation were a stable RSL or gradual RSL fall after the mid-Holocene highstand and a positive sand budget provided by high sublittoral productivity of calcareous shells in combination with erosion at the adjacent sandstone capes and longshore drift.

  10. The curious case of the date of introduction of leaded fuel to Australia: Implications for the history of Southern Hemisphere atmospheric lead pollution

    Science.gov (United States)

    Cook, D. E.; Gale, S. J.

    By comparison with the Northern Hemisphere, the history of atmospheric lead pollution in the Southern Hemisphere is still poorly understood. Until recently, the main source of atmospheric lead fallout in the Southern Hemisphere was tetraethyl lead from motor fuel and for most of the 20th century the most important single source of this pollutant was Australia. Yet there is little agreement over when leaded fuel made its first appearance in Australia. Reported dates range from the early 1920s to the late 1940s. A study of oil company advertisements and reports in motoring and oil company journals shows that leaded petrol first became available in Australia in August 1932. This date is important both for the reconstruction of lead pollution histories and in the use of lead stratigraphies to determine chronology.

  14. Palaeozoic synorogenic sedimentation in central and northern Australia: a review of distribution and timing with implications for the evolution of intracontinental orogens

    International Nuclear Information System (INIS)

    The Palaeozoic Alice Springs Orogeny was a major intraplate tectonic event in central and northern Australia. The sedimentological, structural and isotopic effects of the Alice Springs Orogeny have been well documented in the northern Amadeus Basin and adjacent exhumed Arunta lnlier, although the full regional extent of the event, as well as lateral variations in timing and intensity are less well known. Because of the lack of regional isotopic data, we take a sedimentological approach towards constraining these parameters, compiling the location and age constraints of inferred synorogenic sedimentation across a number of central and northern Australian basins. Such deposits are recorded from the Amadeus, Ngalia, Georgina, Wiso, Eastern Officer and, possibly, Warburton Basins. Deposits are commonly located adjacent to areas of significant basement uplift related to north-south shortening. In addition, similar aged orogenic deposits occur in association with strike-slip tectonism in the Ord and southern Bonaparte Basins of northwest Australia. From a combination of sedimentological and isotopic evidence it appears that localised convergent deformation started in the Late Ordovician in the eastern Arunta lnlier and adjacent Amadeus Basin. Synorogenic style sedimentation becomes synchronously widespread in the late Early Devonian and in most areas the record terminates abruptly close to the end of the Devonian. A notable exception is the Ngalia Basin in which such sedimentation continued until the mid-Carboniferous. In the Ord and Bonaparte Basins there is evidence of two discrete pulses of transcurrent activity in the Late Devonian and Carboniferous. The sedimentological story contrasts with the isotopic record from the southern Arunta lnlier, which has generally been interpreted in terms of continuous convergent orogenic activity spanning most of the Devonian and Carboniferous, with a suggestion that rates of deformation increased in the mid-Carboniferous.

    Fishing and resource use continues to be an essential aspect of life for many Aboriginal communities throughout Australia. It is important for dietary sustenance, and also retains deep social, cultural and economic significance, playing a fundamental role in maintaining group cohesion, transferring cultural knowledge and affirming Indigenous identities. We surveyed approximately 20% of the Gumbaynggirr Aboriginal community of Nambucca Heads, New South Wales, Australia. This paper explores Gumbaynggirr Connection to Country and engagement in cultural practice. It quantifies fishing efforts and consumption of seafood within the community. We found 95% of the sample group fish, with the highest rate of fishing being 2-3 times a week (27%). Furthermore, 98% of participants eat seafood weekly or more frequently, up to more than once a day (24%). Survey results revealed that Myxus elongatus (Sand mullet) and naturally recruited Saccostrea glomerata (Sydney rock oysters) continue to be important wild resources to the Gumbaynggirr community. Trace metals were measured in M. elongatus and S. glomerata samples collected by community participants in this study. Maximum levels prescribed in the Australia New Zealand Food Standards Code were not exceeded in the edible tissue for either species, however both species exceeded the generally expected levels for zinc and copper and S. glomerata samples exceeded the generally expected level for selenium. Furthermore the average dietary exposure to trace metals from consuming seafood was calculated for the surveyed population. Trace metal intake was then compared to the provisional tolerable weekly intake prescribed by the Joint Expert Committee on Food Additives. This process revealed that copper and selenium intake were both within the provisional tolerable weekly intake, while there is no guideline for zinc. Furthermore, participants relying heavily on wild resources from the Nambucca River estuary may exceed the provisional

Climate and soil texture (percent of mineral particles <63 μm) are found to be the dominant controls on δ13CSOC. Of the environmental variables analysed, the strongest correlations to δ13CSOC do not simply occur with res...

  17. Trace element uptake by Eleocharis equisetina (spike rush) in an abandoned acid mine tailings pond, northeastern Australia: Implications for land and water reclamation in tropical regions

    International Nuclear Information System (INIS)

    This study was conducted to determine the uptake of trace elements by the emergent wetland plant species Eleocharis equisetina at the historic Jumna tin processing plant, tropical Australia. The perennial emergent sedge was found growing in acid waters (pH 2.45) and metal-rich tailings (SnAsCuPbZn). E. equisetina displayed a pronounced acid tolerance and tendency to exclude environmentally significant elements (Al, As, Cd, Ce, Co, Cu, Fe, La, Ni, Pb, Se, Th, U, Y, Zn) from its above-substrate biomass. This study demonstrates that geobotanical and biogeochemical examinations of wetland plants at abandoned mined lands of tropical areas can reveal pioneering, metal-excluding macrophytes. Such aquatic macrophytes are of potential use in the remediation of acid mine waters and sulfidic tailings and the reclamation of disturbed acid sulfate soils in subtropical and tropical regions. - Highlights: → In tropical Australia, Eleocharis equisetina grows in an acid mine tailings pond. → Eleocharis equisetina excludes environmentally significant elements from its biomass. → Inspections of equatorial mined lands can reveal metal-excluding aquatic macrophytes. → Such plants are of use in land and water remediation in tropical regions. - The metal-excluding aquatic macrophyte Eleocharis equisetina is of use in land and water remediation in tropical regions.

    2005-04-01

    Using Cape York Peninsula, Queensland, Australia as a case study, this paper combines field sampling of woody vegetation with cost-benefit analysis to compare the social optimality of fire-assisted pastoralism with sustainable forestry. Carbon sequestration is estimated to be significantly higher in the absence of fire. Integration of carbon sequestration benefits for mitigating future costs of climate change into cost-benefit analysis demonstrates that sustainable forestry is a more socially optimal land use than fire-assisted pastoralism. Missing markets for carbon, however, imply that fire-assisted pastoralism will continue to be pursued in the absence of policy intervention. Creation of markets for carbon represents a policy solution that has the potential to drive land use away from fire-assisted pastoralism towards sustainable forestry and environmental conservation.

  1. Sheeted and bulbous pluton intrusion mechanisms of a small granitoid from southeastern Australia: implications for dyke-to-pluton transformation during emplacement

    Fowler, T. J.

    1994-06-01

    The small late syn-tectonic Carboniferous Davys Creek Granite (DCG) of southeastern Australia consists of microgranitic intrusive bodies of diverse geometry and structure. These bodies include: (1) subvertical concordant sheets; (2) bulbous peneconcordant plutons with apophyses and discordant lobes; and (3) subvertical dykes and stocks. The sequence of changing intrusive style is broadly 1-2-3. Transition from 1 to 2 was probably a response to rising magma pressures or declining tectonic stresses. The λ parameter of Emerman and Marrett (1990), which discriminates between stable sheet-like and potential stock/pluton/batholith emplacement modes, adequately predicts the transitions between sheet and pluton emplacements for the DCG. Ductile dyking along actively forming foliations appears to have been an important early intrusive mechanism. A transition from sheet to bulbous pluton intrusion style is suggested to have been in response to magma pressure increases.

    Gully erosion in the seasonally wet tropics of Australia is a major source of sediment in rivers. Stabilization of gullies to reduce impacts on aquatic ecosystems and water storages is a focus for management. However, the cause of the gully erosion is poorly understood and so a critical context for soil conservation is missing. It is uncertain if they are the result of post-European cattle grazing or are they much older and related to non-human factors. The causes of riparian gully erosion along a reach of the Victoria River in the semi-arid tropics of Australia were investigated using several methods. Gully complexes were described and characterised by two major components: a Flood Drainage Channel (FDC) and upslope of this an Outer Erosion Feature (OEF) characterised by badlands set within an amphitheatre. The OEF is likely to be a major source of sediment that appears to be of recent origin. A review of historical records, combined with Optically Stimulated Luminescence (OSL) dating, showed that the FDCs were well established prior to the introduction of domestic stock. It also showed that the badlands began to develop about 90 years ago; that is, about 40 years after the arrival of domestic stock. In addition, an analysis of aerial photos coupled with an on-ground survey and analysis of fallout radionuclides revealed that erosion processes are still active within the gully complexes. While the FDCs are natural drainage channels, cattle grazing probably triggered the badland formation, with the expansion aided by increased rainfall in the past 40 years. Therefore, the OEFs are of human origin and protection from grazing of the riparian zone should slow badland erosion and reduce sediment input to the river.

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

  5. Rock magnetic properties of the Arunta Block, Central Australia, and their implication for the interpretation of long-wavelength magnetic anomalies

    1993-01-01

    Rock magnetic and petrologic studies of a suite of deep crustal rocks from the Arunta Block of Central Australia reveal that the granulite grade rocks are in general much more magnetic than the amphibolite grade samples irrespective of bulk rock composition. The dominant magnetic mineral in all samples is relatively pure magnetite as determined from thermomagnetic and electron microprobe analysis. The bulk magnetic properties are typical of pseudosingle-domain to multidomain size material. The samples from our study have very large remanences compared to previous crustal magnetic studies, with the granulites having a median natural remanent magnetization of 4.1 A/m and Koenigsberger ratio of 7.2. These remanences are relatively resistant to the thermal demagnetization, with nearly 50 percent of the magnetization remaining after 400 C demagnetization. Thus remanence may contribute significantly to the observed magnetic anomalies, including long-wavelength magnetic anomalies, the source of which resides at depth and therefore at elevated temperature, where a thermoviscous remanant magnetization along the present-day field is likely to dominate.

  6. The structural controls of gold mineralisation within the Bardoc Tectonic Zone, Eastern Goldfields Province, Western Australia: implications for gold endowment in shear systems

    The Bardoc Tectonic Zone (BTZ) of the late Archaean Eastern Goldfields Province, Yilgarn Craton, Western Australia, is physically linked along strike to the Boulder-Lefroy Shear Zone (BLSZ), one of the richest orogenic gold shear systems in the world. However, gold production in the BTZ has only been one order of magnitude smaller than that of the BLSZ (˜100 t Au vs >1,500 t Au). The reasons for this difference can be found in the relative timing, distribution and style(s) of deformation that controlled gold deposition in the two shear systems. Deformation within the BTZ was relatively simple and is associated with tight to iso-clinal folding and reverse to transpressive shear zones over a <12-km-wide area of high straining, where lithological contacts have been rotated towards the plane of maximum shortening. These structures control gold mineralisation and also correspond to the second major shortening phase of the province (D2). In contrast, shearing within the BLSZ is concentrated to narrow shear zones (<2 km wide) cutting through rocks at a range of orientations that underwent more complex dip- and strike-slip deformation, possibly developed throughout the different deformation phases recorded in the region (D1-D4). Independent of other physico-chemical factors, these differences provided for effective fluid localisation to host units with greater competency contrasts during a prolonged mineralisation process in the BLSZ as compared to the more simple structural history of the BTZ.

    The Archean Biosphere Drilling Project (ABDP) drilled a continuous 270 m long oriented core from the Towers Formation, which includes the Marble Bar Chert Member (3456.1-3476.0 Ma) in the Pilbara craton, northwestern Australia. A paleomagnetic study of 261 discrete specimens, collected from a 158.5 to 182.0 m section of the Marble Bar Chert Member, revealed two distinct magnetic components (LT and MT). The MT component yields seven different mean paleomagnetic directions clustered as MB1 to MB7. These, together with the published paleomagnetic poles of early Archean rocks from the Pilbara craton, draw a continuous paleomagnetic pole path, which likely to be regarded as the early to late Archean apparent polar wander path (APWP) for the Pilbara craton. The APWP implies that the Pilbara craton underwent a latitudinal drift of about 21° during the interval when the magnetization of the Marble Bar Chert Member was acquired. The estimated speed of the lateral drift is 12-112 cm/yr (120-1120 km/Myr), which is large compared with current plate motion velocities, suggesting that continents might have moved during the Archean faster than in the Phanerozoic.

  8. U-Th-Pb systematics of some granitoids from the northeastern Yilgarn Block, Western Australia and implications for uranium source rock potential

    International Nuclear Information System (INIS)

    The Mount Boreas-type granite and spatially associated syenitic granitoid of Western Australia yield Pb-Pb ages of 2370 +- 100 Ma and 2760 +- 210 Ma, respectively. Th-Pb ages, although less precise, are concordant with these ages, and therefore the apparent ages are interpreted to be the crystallisation ages for these two units. U-Pb ages are variable and for the most part anomalously old, which suggests a Cainozoic uranium loss. However, this loss is generally small (3μg/g); therefore, neither granitoid in its fresh state provides a good source for nearby calcrete-hosted uranium deposits. The possibility remains that the Mount Boreas-type granite that has been completely weathered during the Tertiary could have been a source for the calcrete-type uranium deposits in W.A. Although the Mount Boreas-type granite is highly fractionated, it does not bear a strong geochemical imprint of a sedimentary precursor. This feature contrasts it with apparently fresh granitoids from other parts of the world that have lost large amounts of uranium (approx. 20μg/g) and are associated with large roll-type and other low temperature-type uranium deposits

  10. Constraints on the composition of ore fluids and implications for mineralising events at the Cleo gold deposit, Eastern Goldfields Province, Western Australia

    International Nuclear Information System (INIS)

    The Cleo gold deposit, 55 km south of Laverton in the Eastern Goldfields Province of Western Australia, is characterised by banded iron-formation (BIF)-hosted ore zones in the gently dipping Sunrise Shear Zone and high-grade vein-hosted ore in the Western Lodes. There is evidence that gold mineralisation in the Western Lodes (which occurred at ca 2655 Ma) post-dates the majority of displacement along the Sunrise Shear Zone, but it remains uncertain if the ore in both structures formed simultaneously or separately. Overall, the Pb, Nd, Sr, C, O and S isotopic compositions of ore-related minerals from both the Western Lodes and ore zones in the Sunrise Shear Zone are similar. Early low-salinity aqueous-carbonic fluids and late high-salinity fluids with similar characteristics are trapped in inclusions in quartz veins from both the Sunrise Shear Zone and the Western Lodes. The early CO2, CO2-H2O, and H2O-dominant inclusions are interpreted as being related to ore formation, and to have formed from a single low-salinity aqueous-carbonic fluid as a result of intermittent fluid immiscibility. Homogenisation temperatures indicate that these inclusions were trapped at approximately 280 deg C and at approximately 4 km depth, in the deeper epizonal range. Differences between the ore zones are detected in the trace-element composition of gold samples, with gold from the Sunrise Shear Zone enriched in Ni, Pb, Sn, Te and Zn, and depleted in As, Bi, Cd, Cu and Sb, relative to gold from the Western Lodes Although there are differences in gold composition between the Sunrise Shear Zone and Western Lodes, and hence the metal content of ore fluids may have varied slightly between the different ore zones, no other systematic fluid or solute differences are detected between the ore zones. Given the fact that the ore fluids in each zone have very similar bulk properties, the considerable differences in gold grade, sulfide mineral abundance, and ore textures between the two ore zones

    Soil amendments can immobilize metals in soils, reducing the risks of metal exposure and associated impacts to flora, fauna and human health. In this study, soil amendments were compared, based on "closed system" water extracts, for reducing metal mobility in metal-contaminated soil from the Broken Hill mining center, Australia. Phosphatefertilizer (bovine bone meal, superphosphate, triple superphosphate, potassium orthophosphate) and pine bark (Pinus radiata) were applied to two soils (BH1, BH2) contaminated with mining waste. Both soils had near neutral to alkaline pH values, were sulfide- or sulfate-rich, and contained metal and metalloid at concentrations that pose high environmental risks (e.g., Pb = 1.25 wt% and 0.55 wt%, Zn = 0.71 wt% and 0.47 wt% for BH1 and BH2, respectively). The addition of fertilizers and/or pine bark to both soil types increased water extractable metals and metalloids concentrations (As, Cd, Cu, Fe, Mn, Pb, Sb, Zn) compared with nonamended soils. One or more of the elements As, Cd, Cu, Mn, Pb, and Zn increased significantly in extracts of a range of different soil+pine bark and soil+fertilizer+piner+pine bark tests in response to increased pine bark doses. By contrast, Fe and Sb concentrations in extracts did not change significantly with pine bark addition. Solution pH was decreased by phosphate fertilizers (except for bovine bone meal) and pine bark, and pine bark enhanced dissolved organic carbon. At least in the short-term, the application of phosphate fertilizers and pine bark proved to be an ineffective method for controlling metal and metalloid mobility in soils that contain admixtures of polymetallic, polymineralic mine wastes.

    Leucocratic quartzofeldspathic gneisses form a significant proportion of the lower part of the Palaeoproterozoic Willyama Supergroup sequence in the Olary Block, South Australia and have correlatives in the adjacent Broken Hill Block. Field and geochemical data demonstrate that these rocks were originally rhyolitic volcanics and granite, with A-type affinities consistent with magma production during intracratonic rifting, supporting tectonic models proposed for the Willyama Supergroup in the Broken Hill Block. Although the rocks have characteristic high-field-strength element enrichment, many have undergone extensive pervasive pre- or syn-metamorphic sodic alteration and are typically rich in albite. Sensitive high resolution ion microprobe (SHRIMP) U-Pb zircon data tightly constrain the depositional and early intrusive history. Zircons from an interpreted metavolcanic rock containing relict quartz phenocrysts yield an age of 1699 ± 10 Ma, whereas a metagranitoid sample has an age of 1703 ± 6 Ma. These results are compatible with recent geochronological data on felsic metavolcanic rocks from the Broken Hill Block (Page and Laing, 1992) and are indicative of widespread magmatism during deposition of the Willyama Supergroup. Nd signatures for the two Olary Block samples imply the presence of a significant component from a depleted mantle source. The A-type metavolcanic rocks are locally associated with small iron formations, some of which grade into stratiform barite-rich horizons. Although potentially favourable for sediment-hosted exhalative PbZn mineralisation, the Fe- and Ba-rich units, along with transgressive vein and breccia occurrences of Fe oxides ± quartz ± pyrite cutting both the metavolcanic and metagranitoid rocks, may be more prospective for epigenetic Cu-Au mineralisation related to later metamorphic and/or magmatic events. Partial melting of the A-type suite during high grade regional metamorphism at ~ 1600 ± 20 Ma led to the formation of local

    The peak of the recent prolonged 'Millennium Drought' (1997-2011) triggered an episode of widespread mass failure in the alluvial river-banks of the Lower Murray River in South Australia. Multi-beam surveying of the channel and submerged river-banks between Mannum and Murray Bridge and coring of the bank sediments has been undertaken in sections of the river where large bank failures threatened private housing or public infrastructure. This data demonstrates that the bank materials are soft, horizontally-layered muds and that translational, planar slab-slides have frequently occurred in permanently submerged portions of the Murray's river banks. Despite these riverine features being several orders of magnitude smaller than the translational submarine landslides of the continental margins, the submerged river-bank slides are strikingly similar in their morphology to their submarine equivalents. Intriguingly, the Murray River translational slide failure-surfaces are usually developed as river-floor-parallel features in a manner similar to many submarine landslides which present failure-surfaces that are developed on seafloor-parallel, bedding planes. In contrast however, the Murray's river-bank slides occur on steep slopes (>20o) and their failure surfaces must cut across the horizontal laminations and layering of the muds at a relative high angle which removes the possibility of a weak sediment layer being responsible for the occurrence of these failures. Modelling of the river-bank failures with classical soil mechanics methods and the measured physical properties of the river-bank materials indicates that the failures are probably a consequence of flood-flow scour removing the bank-slope toe in combination with pore-pressure effects related to river-level fluctuation (ie. drawdown). Nevertheless, the Murray's translational slab-slides provide a reliable example of slope-parallel planar failure in muds that does not require a stratigraphic weak layer to explain the

  14. Mapping and quantifying groundwater inflows to Deep Creek (Maribyrnong catchment, SE Australia) using 222Rn, implications for protecting groundwater-dependant ecosystems

    International Nuclear Information System (INIS)

    Highlights: • Groundwater inflows in a chain-of-ponds river quantified. • Groundwater inflow vs. discharge relationship determined using Rn. • First long-term continuous Rn monitoring in a river indicates temporal changes to groundwater inflows. • Application to protection of groundwater-dependant ecosystems. - Abstract: Understanding groundwater inflows to rivers is important in managing connected groundwater and surface water systems and for protecting groundwater-dependant ecosystems. This study defines the distribution of gaining reaches and estimates groundwater inflows to a 62 km long section of Deep Creek (Maribyrnong catchment, Australia) using 222Rn. During summer months, Deep Creek ceases to flow and comprises a chain of ponds that δ18O and δ2H values, major ion concentrations, and 222Rn activities imply are groundwater fed. During the period where the river flows, the relative contribution of groundwater inflows to total river discharge ranges from ∼14% at high flow conditions to ∼100% at low flows. That the predicted groundwater inflows account for all of the increase in discharge at low flow conditions lends confidence to the mass balance calculations. Near-continuous 27 week 222Rn monitoring at one location in the middle of the catchment confirms the inverse correlation between river discharge and relative groundwater inflows, and also implies that there are limited bank return flows. Variations in groundwater inflows are related to geology and topography. High groundwater inflows occur where the river is at the edge of its floodplain, adjacent to hills composed of basement rocks, or flowing through steep incised valleys. Understanding the distribution of groundwater inflows and quantifying the contribution of groundwater to Deep Creek is important for managing and protecting the surface water resources, which support the endangered Yarra pygmy perch

    U-series ages using methods of thermal ionisation mass spectrometry (TIMS) are reported for Last Interglacial fossil reefs along the stable coastal margin of Western Australia. Thorium isotope ratios were measured with superior precision using methods of charge collection. High levels of precision in the measurement of both uranium and thorium isotopes has reduced the age uncertainty due to analytical errors, excluding the uncertainty in the decay constants, by a factor of four over the precisions reported by many earlier TIMS workers. Uncertainties in δ234U(T), determined from both 230Th/ 238U and 234U/ 238U, are also significantly smaller than previously reported, allowing samples which have undergone diagenetic exchange of uranium and thorium to be more easily identified. Strict criteria were adopted to screen the new Western Australian data. Reliable ages range from 127 to 122 ka. Published TIMS observations from other localities have been assessed using the same strict criteria. When these are combined with glacio-hydro isostatic sea-level models they indicate that the Last Interglacial period occurred from at least 130 to 117 ka. However, these age constraints are largely determined from single data points and need to be verified with additional ages before considering them to be robust estimates for the timing of onset and termination of the Last Interglacial. Globally, the main episode of reef growth appears to be confined to a narrow interval occurring from 127 to 122 ka, in direct agreement with the narrow range in ages obtained from the Western Australian sites. This may indicate that the Last Interglacial was of short duration, extending from 127 to 122 ka only. Alternatively, this interval may reflect a major reef-building event in the middle of a longer duration (130-117 ka) interglacial interval.

    The late Paleozoic to early Mesozoic southern New England Orogen of eastern Australia exhibits a remarkable omega-shaped orogenic curvature (orocline), but the geodynamic processes responsible for the formation of the orogenic curvatures (oroclines) are still unclear. Oroclinal bending took place during the early Permian, simultaneously with the development of rift-related sedimentary basins (Sydney, Gunnedah and Bowen basins), which bound the oroclines to the west. The Nambucca Block is part of another early Permian rift basin that is situated farther east, in the core of the oroclinal structure. We present new stratigraphic, structural and geochronological data from the Nambucca Block in an attempt to better understand its provenance, tectonic history and its role in the formation of the oroclines. Four phases of folding and associated structural fabrics are recognised in the Nambucca Block. 40Ar/39Ar age of metamorphic micas from the second deformational phase provides a minimum depositional age constraint at 275-265 Ma. This age overlaps with the timing of oroclinal bending, suggesting that the first two phases of deformation resulted from the same mechanism that formed the oroclines. Detrital zircon geochronology (U/Pb ICP-MS ages) of six samples from the Nambucca Block constrains the maximum depositional age of the sequence to 280 Ma. The sedimentary succession, though extremely polymictic, is unimodal in its sources, and is therefore interpreted to consist mainly of recycled detritus from a Devonian-Carboniferous accretionary complex. We propose a model for oroclinal bending involving three stages. The first stage, starting at about 293 Ma and including the deposition of the sequence of Nambucca (i.e. overlaps with the 280-265 Ma time constraint), was associated with formation of rift basins in an extensional backarc setting. This was followed by N-S contraction, which gave rise to second-order oroclinal structures. The third and final stage involved

  17. Clay vein and its implication for uranium exploration activity in the northern part of the Alligator Rivers Uranium Field, northern Australia

    International Nuclear Information System (INIS)

    Clay veins have been found by uranium exploration drilling around the Black Rock uranium prospect in the northern part of the alligator Rivers Uranium Field (ARUF), northern Australia. The mineralogical and chemical features are described to clarify relations with uranium mineralization, because it is not accompanied by uranium mineralization. X-ray diffraction and chemical analysis for major elements indicate that the clay vein consists mainly of chlorite (clinochlore to ferroan clinochlore) and lesser mica clay mineral (t-1M dominant). The clay vein is compared with the clay alteration zone around the uranium deposits in ARUF in terms of mode of occurrence, mineral and chemical compositions. Mineral composition of the clay vein is only in accordance with that of the inner alteration halo of the clay alteration zone. It is, however, different from mineral composition of the outer alteration halo in terms of lack of Fe chlorite in the clay vein. Chemical composition of the clay vein is similar to that of the clay alteration zone, except for lack in the vein of high iron content which is observed in some samples of the alteration zone. As a whole, the feature of the clay vein corresponds to the inner alteration zone around the uranium deposit in ARUF. The mode of occurrence of the clay vein is very different from that of the clay alteration zone. Mode of occurrence, and mineral and chemical compositions of the clay vein resemble a chlorite vein in the Lower to Middle Proterozoic sandstone above the Jabiluka deposit, one of major uranium deposit in the ARUF. Because of the similarity between the clay and the chlorite veins, the clay vein is regarded as marginal facies of an alteration zone. The fluid that formed the clay vein is estimated to have been oxidized, because of the existence of hematite and ubiquitous Mg chlorite. This nature is in accordance with the mineralizing fluid that formed the inner alteration zone in the Nabarlek deposit. In conclusion, the vein

Finding political support in Australia's progressive arts policies of the late 1970s, community music is discussed as embracing the principles of access and equity and supporting the development of musical skills in the context of social change and…

  20. Seasonal changes of redox potential and microbial activity in two agricultural soils of tropical Australia: some implications for soil-to-plant transfer of radionuclides

    International Nuclear Information System (INIS)

    Very little is known of the factors controlling soil-to-plant transfer of radionuclides in tropical environments. As part of an IAEA/FAO coordinated research project (CRP) designed to elucidate some of those factors, near-surface samples of two agricultural red-earth soils (Blain and Tippera) were collected from a study site in the Northern Territory. The climate is tropical monsoonal with crops being grown over the wet season from December to March/April. It is important to understand soil variables that may be related to this dramatic seasonality. In this investigation, soil redox state and microbial populations were assessed before and after the growing season with a view to generating hypotheses for future evaluation. The X-ray absorption near edge structure (XANES) technique was used to determine overall changes in the solid-state redox speciation of Fe and Mn in soils across the growing period. Fe speciation did not change but approximately 10% of the total Mn was oxidised from Mn(II) to Mn(III) and Mn(IV) in both soils between October 1999 and April 2000. An apparent disconnect between Fe and Mn was not unexpected given the >10 times higher concentration of Fe in the soils compared with Mn. These results have implications for the bioavailability of redox sensitive radionuclides such as Tc and Pu. Similarly, microbial population estimates were derived before and after the growing period. Total bacterial populations did not vary from 106 to 107 colonies per gram. Fungal populations increased over the growing season from 3-6x105 to 1-4x106 colonies per gram of soil. Fungi have the potential to decrease soil pH and hence increase the bioavailability of radionuclides such as Cs. In addition, fungi act to facilitate plant nutrition. This could lead to enhanced accumulation of nutrient analogues (e.g. Sr and Ra for Ca; Tc for Mn), but this effect may be masked by improved biomass production

  3. Uranium production in Australia

    International Nuclear Information System (INIS)

    The history of uranium mining and milling in Australia is briefly outlined, particular attention being given to the development of Australia's only two operating mills, Nabarlek and Ranger, and its only operating mine, Ranger. The latter project is used to illustrate the prerequisites for development of the industry and the complex roles of the various parties involved in establishing a new mine: equity holders, customers, financiers, the securities industry, trade unions, and the public. The moves currently being taken to resolve the future of the industry in Australia, particularly the examination of issues relating to Australia's role in the nuclear fuel cycle being conducted by the Australian Science and Technology Council, preclude any firm conclusions being drawn, but the various options open to the government are reviewed and the record of Australian governments and unions and the attitude of the Australian public are described.

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

  7. Australia's uranium export policy

    International Nuclear Information System (INIS)

    In developing the policy framework for the export of uranium, successive governments have been keenly aware that, in Australia, as in most countries, there has been considerable community interest and controversy surrounding the subject of uranium. When the Australian Labor Government was elected in 1983, it commissioned the Australian Science and Technology Council (ASTEC) to report on Australia's role in the nuclear fuel cycle. In particular, the report examined: (i) Australia's nuclear safeguards arrangements, giving particular attention to the effectiveness of the bilateral and multilateral agreements and to the scope for strengthening these agreements, (ii) the opportunities for Australia through the conditions of its involvement in the nuclear fuel cycle to further advance the cause of nuclear non-proliferation having regard to the policies and practices of recipient countries, (iii) the adequacy of existing technology for the handling and disposal of waste products by consuming countries, and the ways in which Australia could further contribute to the development of safe disposal methods.

    No single issue has dominated health practitioners' ethical debates in 2014 in Australia, but a controversial decision on gene patenting and the media focus on "Dr. Death," euthanasia campaigner Dr. Philip Nitschke, have given new life to these two familiar (and global) debates. Currently a dying with dignity bill, drafted by the Australian Green Party, is under examination. The Senate inquiry into the bill received more than 663 submissions, with 57% opposed and 43% in support of the bill, which has now been referred to a Senate committee. Will this be another of Australia's failed attempts to legalize euthanasia? The trial of Dr. Nitschke begins on November 10, 2014. PMID:27348826

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

  13. Australia: a continuing genocide?

    Science.gov (United States)

    Short, Damien

    2010-01-01

    Debates about genocide in Australia have for the most part focussed on past frontier killings and child removal practices. This article, however, focuses on contemporary culturally destructive policies, and the colonial structures that produce them, through the analytical lens of the concept of genocide. The article begins with a discussion of the meaning of cultural genocide, locating the idea firmly in Lemkin's work before moving on to engage with the debates around Lemkin's distinction between genocide and cultural 'diffusion.' In contrast to those scholars who prefer the word 'ethnocide,' the underlying conceptual contention is that the term 'cultural genocide' simply describes a key method of genocide and should be viewed, without the need for qualification, as genocide. While direct physical killing and genocidal child removal practices may have ceased in Australia, some indigenous activists persuasively contend that genocide is a continuing process in an Australia that has failed to decolonise. Concurring with these views the article argues that the contemporary expression of continuing genocidal relations in Australia can be seen principally, and perversely, in the colonial state's official reconciliation process, native title land rights regime and the recent interventionist 'solutions' to indigenous 'problems' in the Northern Territory.

  15. Australia's nuclear graveyard

    International Nuclear Information System (INIS)

    Britain and Australia have become locked in a battle of wills and wits over a nuclear legacy that is now more than 30 years old. At stake is the issue of who will pay to clean up a stretch of the central Australian outback where at least 23 kilograms of plutonium are buried in nuclear graveyards or scattered in fine particles on the ground. The plutonium was left there after a series of British nuclear weapons tests in the 1950s and 1960s. The cost of cleaning it up today, and rendering the ground safe the the Aborigines who claim it as their tribal homeland, has been estimated at up to $158 million. Australia's minister for resources, Senator Gareth Evans, went to London in October 1986 to try to involve the British in the cleanup. But Britain is still taking the stand that it had discharged any obligations on this score long ago. This question is at the heart of controversy that began mounting in the late 1970s over the British nuclear tests. It was then that Aborigines and test veterans from Britain and Australia started alleging that they had been exposed to unduly high doses of radiation. Clearly, the nuclear tests, which began as a political exercise between Britain and Australia more than 30 years ago, seem destined to remain the source of much legal, diplomatic, and financial fallout between the two countries for a long time to come

    Australia had a population of 17.6 million in 1991. In 1992, Australia's population grew at the rate of 1.06%, 0.8% due to natural increase and 0.26% from immigration. The recent Australian Bureau of Statistics Report estimates that it will grow to 18.9 million by the end of the century and 23.1 million by 2025, assuming fertility remains at current levels and net migration stabilizes at 70,000 per annum from the year 2000. The World Bank estimates that Australia's population will stabilize at 25 million some time in the future. Since Australia's politicians and economists fail to understand that the country already has a large enough population, no national population policy has been declared. The Department of Immigration and Ethnic Affairs, responsible for all population issues, gives no thought to the long-term environmental consequences of the rapidly growing population and determines the annual migrant intake simply on the basis of the nation's economic needs, demands from new immigrants for admission of their next of kin, and humanitarian considerations with regard to refugees. Population growth in Australia needs to be checked as soon as possible. Reducing the annual migrant intake to below 50,000, Australia could achieve a stable population of approximately 23 million by 2040; the annual intake of 150,000 immigrants will grow the population to 37 million. The total fertility rate (TFR) has been below replacement level since 1976, but the population's skewed age distribution will cause it to continue to grow through natural increase at the current rate of approximately 0.8% per year for some time to come. Improving educational opportunities for women and ensuring that all have ready access to modern contraception could help produce a further decline in TFR. Moreover, education about contraception must be made a part of every school curriculum. Steps taken now may avert any future flood of millions of ecological refugees from Southeast Asia, particularly

  19. Australia's uranium export potential

    International Nuclear Information System (INIS)

    During the period 1954-71 in Australia approximately 9000 MT of U3O8 was produced from five separate localities. Of this, 7000 MT was exported to the United Kingdom and United States and the balance stockpiled by the Australian Atomic Energy Commission (AAEC). Australia's uranium ore reserves occur in eight deposits in three states and the Northern Territory. However, 83% of Australia's reserves are contained in four deposits in lower Proterozoic rocks in the East Alligator River region of the Northern Territory. The AAEC has calculated Australia's recoverable uranium reserves by eliminating estimated losses during the mining and milling of the ores. AAEC has estimated reasonably assured resources of 289,000 MT of uranium at a recovery cost of less than US$80 per kilogram uranium. The companies have collectively announced a larger ore reserve than the Australian Atomic Energy Commission. This difference is a result of the companies adopting different ore reserve categories. On August 25, 1977, the federal government announced that Australia would develop its uranium resources subject to stringent environmental controls, recognition of Aboriginal Land Rights, and international safeguards. Australian uranium production should gradually increase from 1981 onward, growing to 10,000 to 15,000 MT by 1985-86. Further increases in capacity may emerge during the second half of the 1980s when expansion plans are implemented. Exploration for uranium has not been intensive due to delays in developing the existing deposits. It is likely that present reserves can be substantially upgraded if more exploration is carried out. 6 figures, 3 tables

  20. Nucleopolyhedrovirus Introduction in Australia

    2007-01-01

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

    The paper reviews the history and growth of the mineral industry in Australia and its significance to the nation's economic growth and overseas trade, particularly over the last twenty years during which time production of coal, iron ore, manganese and mineral sands has increased greatly and new discoveries of petroleum, bauxite and nickel have given rise to major new industries. Australia ranks fourteenths in the value of world trade and is among the world's largest exporters of alumina, iron ore, mineral sands, coal, lead, zinc and nickel. Some details of production, processing and exports of the major minerals are given. Comment is made on the policies and roles of the six State Governments and the Federal Government in respect of ownership and control of the mining, processing and exporting of both energy and non-energy minerals.

  2. WAVFH delegates' reports: Australia

    International Nuclear Information System (INIS)

    Radiation measuring and control before Chernobyl: Continuous measurements of fallout in different parts of Australia, including the food producing areas, have been made since the mid 1950s. Levels have decreased rapidly since the cessation of atmospheric nuclear tests in the Southern Hemisphere in 1974 and in the Northern Hemisphere in 1980. Measurements of concentrations of radionuclides arising from fallout were made for the major groups of foods affected by the radioactive contaminants, starting in the 1950s and continuing until concentrations were so low that further effort in measurement was not warranted, i.e., less than 0.1 Bq/kg or 0.1 Bq/l. Changes in the concentrations of radionuclides in foods follow the same trends as the fallout levels. Based on the low levels of fallout measured in Australia since the 1950s, and taking into account the extremely low levels during the past decade, the concentrations of radionuclides arising from fallout in foods grown and processed in Australia are extremely small. Results from the fall-out from Chernobyl. Since the Chernobyl accident, measurements of the concentrations of 137Cs in a variety of foodstuffs grown in Australia have been made, mainly for export purposes. A summary of the results of these measurements is given in Table 111 of Attachment 2. No 134Cs has been detected, nor is it likely to be. By taking into account these measurements, the earlier measurements of foodstuffs, predictive modelling values and the very low levels of fall-out in deposit and in air, it is concluded that the concentrations of 137Cs in all foodstuffs grown in Australia are extremely small. Accordingly, their consumption would result in no significant risk to the health of a population. With world atmospheric conditions being as they are, it will probably be 12 to 18 months before any fallout reaches Australia. Even if some fall-out does occur, it will be minimal and should not significantly increase our very low natural levels. Thus

  3. Pleistocene Paleoart of Australia

    2014-02-01

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

  9. Australia's energy profile

    International Nuclear Information System (INIS)

    Australian Bureau of Agricultural and Resource Economics (ABARE)'s biennial fuel and electricity survey provides a comprehensive database with which is possible to examine recent trends and developments in Australia's energy market. Some key development are outlined in this article. While energy consumption in Australia has been increasing steadily since 1973-74, substantial changes have occurred 'behind the scenes' in terms of the states and sectors in which energy is consumed and the overall fuel mix. Historically, the south-eastern states of New South Wales and Victoria have accounted for the largest shares of total energy consumption In recent years, however, the dominance of New South Wales and Victoria (and particularly New South Wales) has come under pressure from the states of Queensland. Western Australia, and to a lesser extent, the Northern Territory. Each of these states has experienced rapid growth in energy consumption, due mainly to a number of strongly growing energy intensive industries, particularly in the mining and minerals processing sectors. High economic and population growth over this period were also important factors. An increase in the share of natural gas- and a corresponding decline in the share of crude oil - is the most evident change to have occurred in the fuel mix since 1973-1974. However, since 1993, the trend has changed, the share of coal (and particularly brown coal) increased strongly, making it the primary fuel source for thermal electricity generation. This recent shift has been driven by developments in Queensland and Victoria

  10. Australia's atomic conspiracy theory

    International Nuclear Information System (INIS)

    The author questions claims by the Newcastle University historian Wayne Reynolds in his book 'Australia's Bid for the Bomb', that the impetus behind the Snowy Mountains Scheme was to provide a secure source of power for the enrichment of uranium and production of heavy water so that Australia could produce its own atomic bombs. Reynolds also argued that the Australian Atomic Energy Commission (AAEC) was set up so that Australia had a trained scientific workforce to produce plutonium for the bomb. While the book is well researched, Reynolds does not seem to understand the principles of basic science and engineering. After the Second World War, a manufacturing and industrial base with a skilled and trained workforce was needed so it could be converted to war or defence manufacturing when the need arose. This new manufacturing community would require electrical power to sustain it. Hydroelectricity and atomic energy could help provide these needs. Even though war was still raging, Prime Minister John Curtin looked ahead and set up a Department of Post-War Reconstruction. It was through this department that the Snowy Mountains Scheme would be established. Curtin did not live to see this. He died in 1945 but his successor, Ben Chifley, continued the vision. The author believes, an understanding of the science behind these developments and an appreciation of how how humans interact with each others when it comes to getting something they want is likely to give a more balanced view of the past

  11. Australia needs nuclear education

    International Nuclear Information System (INIS)

    A matter of increasing concern in Australian society is the absence of a Commonwealth Government policy on the peaceful use of nuclear energy. The lack of University level teaching facilities in nuclear energy engineering is also perceived to be an issue of national importance which must be addressed. More and more Australians deeply regret the lack of informed realism and scientific integrity which goes into endless debates on the technical, environmental and societal aspects of nuclear energy. Within the Australian community such important issues as uranium mining in Kakadu National Park, research reactor operation at Lucas Heights, the establishment of an international nuclear waste repository in Western Australia or the domestic use of nuclear electricity generation to minimise Australia's greenhouse emissions are still being debated at the intellectual level of radio talkback programs. Decision making in such areas deserves the disciplines of appropriate tertiary education. The Australian community has a right to know the relative risks and the environmental impacts of various fuel cycles as well as the technical limitations, true costs and energy audits of the 'alternative' energy technologies. Presently the Commonwealth of Australia is without a single School of Nuclear Engineering operating at a University level. Such a situation is believed to be unprecedented amongst the developed countries of the world. It is viewed with a measure of incredulity by the academic, diplomatic and political communities of the 'developing' countries of East Asia and the Pacific Basin. Many of these have a massive investment in the growth of peaceful nuclear energy and nuclear science and technology within their borders. Copyright (1999) Australian Institute of Energy News

    2008-01-01

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

    1996-01-01

    "This paper presents an overview of Asian student migration to Australia, together with an analysis of political and educational aspects of the overseas student programme. It focuses on some significant consequences of this flow for Australia. The characteristics of key student groups are contrasted to provide some perspective of the diversity of historical and cultural backgrounds, with the source countries of Malaysia, Indonesia and PRC [China] selected as case studies. Since the issue of PRC students in Australia has attracted considerable public attention and policy consideration, particular focus is placed on their experience."

    1990-01-01

    Numerous algae reefs are seen in Shark Bay, Western Australia, Australia (26.0S, 113.5E) especially in the southern portions of the bay. The south end is more saline because tidal flow in and out of the bay is restricted by sediment deposited at the north and central end of the bay opposite the mouth of the Wooramel River. This extremely arid region produces little sediment runoff so that the waters are very clear, saline and rich in algae.

  2. Rethinking "Commercial" Surrogacy in Australia.

    Science.gov (United States)

    Millbank, Jenni

    2015-09-01

    This article proposes reconsideration of laws prohibiting paid surrogacy in Australia in light of increasing transnational commercial surrogacy. The social science evidence base concerning domestic surrogacy in developed economies demonstrates that payment alone cannot be used to differentiate "good" surrogacy arrangements from "bad" ones. Compensated domestic surrogacy and the introduction of professional intermediaries and mechanisms such as advertising are proposed as a feasible harm-minimisation approach. I contend that Australia can learn from commercial surrogacy practices elsewhere, without replicating them. PMID:25015592

  3. Indigenous actinorhizal plants of Australia

    Indian Academy of Sciences (India)

    Nishath K Ganguli; Ivan R Kennedy

    2013-11-01

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

  4. Environmental radioactivity in Australia

    International Nuclear Information System (INIS)

    Environmental research mainly carried out at Australian Nuclear Science and Technology Organization (ANSTO) related to nuclear activities in Australia such as uranium mining, transfer factor studies related to U- and Th-series radionuclides, dose assessment modelling, radiation monitoring, and nuclear waste repository, is outlined. Many aspects of radioecology, marine and freshwater geochemistry and radiochemical dating techniques; bioaccumulation including archival monitoring and kinetics, ground water studies, atmospheric issues including climate change and geomorphology are being studied with the help of a high neutron flux reactor, a cyclotron and a tandem accelerator as well as modern analytical equipment. Only a very small number of examples of radioactivity applications are presented: Microbiotic crusts covering up to 50% of the soil surface at Maralinga nuclear test site where more than 80% of the residual Am-241 was found to retain within the top 5 mm after 30 years. SIMS analysis of crocodile bones indicating that the only metal affected by U mining in Kakadu region was lead (Pb). In mineral sands such as zircon, U(VI) is more stable than U(IV) as evidenced by ion beam and SEM imaging and XANES analysis. Use of radioisotopes in atmospheric and climate studies, terrestrial studies particularly in dating techniques, and aquatic-continental and aquatic-ocean waters, and in biological studies such as biokinetics of copper metabolism in rainbow fishes living downstream of a mine are presented.

  5. Neutron scattering in Australia

    International Nuclear Information System (INIS)

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

  8. Australia's unresolved nuclear problems

    International Nuclear Information System (INIS)

    This paper examines three acts of monumental incompetence which have all but destroyed Australia's once great potential to play a leading role in nuclear technology in South East Asia. Political chicanery and monumental technological and economic foresight, professional weakness and vacillation in the engineering community and the vicious pseudo scientific propaganda of most branches of the media, the teaching profession and sadly, even the politicisation of our churches, has all but destroyed a potential Australian ''sunrise industry''. Over the next forty years the population of planet Earth will approximately double. Unless Australians realise that their children and grand-children, and future generations of our neighbouring third world countries will require nuclear technology for an equitable and acceptable shared life-style, they will continue to allow taxpayers' money to be wasted on costly, technically unacceptable and environmentally undesirable attempts to develop ''alternative'' or ''renewable'' energy sources. These are neither alternative nor renewable but politically trendy. The tragedy of such projects is that their limited applicability and suitability for small scale energy production by wealthy users in limited geographical locations will only increase the need for base load energy supplies of the conventional type. Unless this is nuclear, planet Earth faces environmental despolation of monumental proportions. (J.P.N.)

  9. The nuclear industry in Australia

    International Nuclear Information System (INIS)

    The history of the development of the nuclear industry in Australia is essentially the history of uranium mining. Australia is a significant exporter of uranium concentrate yellowcake, but no other nuclear power or fuel cycle activity exists on a commercial scale. Industrial radiation processing and the production of radioisotopes and radio-pharmaceuticals are the only other endeavors. The uranium mining in early years and the second discovery period, the policy formulation in 1970s and the recent policy development are described. Australia's low cost reserve has risen to 474,000 t U, and in 1984, three mines produced around 4,400 t U as yellowcake. Once the Jervis Bay nuclear power plant with 500 MWe capacity was planned, but the project was postponed indefinitely. The Uranium Enrichment Group of Australia planned to build an enrichment plant as a joint venture with URENCO Ltd., but also this plan was interrupted. The lack of expansion into nuclear power and fuel cycle activities has been due to favorable fossil fuel resources and their distribution, population density and distribution, social factors and government policy in Australia.

    The North West Shelf Venture is based in Karratha, 1500 km north of Perth in Western Australia. At a cost of $A12bn, it is the biggest and one of the most important natural resource developments in Australia. Originally constructed in 1984 to supply gas to the West Australian domestic and industrial market, the Venture is now the third-largest LNG exporter in the Asia-Pacific region, generating more than $A1.5bn a year in export income. The Venture supplies about 15 percent of Japan's LNG demand, or 7.5 million tonnes a year, to eight Japanese power and gas utilities under 20-year contracts. In addition, 'spot' sales have been made to Spain, South Korea, Turkey and the United States. The Venture also supplies more than 70 percent of Western Australia's domestic gas requirements and exports LPG, condensate and crude oil to global markets

  12. Australia's uranium policy: an examination

    International Nuclear Information System (INIS)

    The mining and export of Australian Uranium poses problems for the safety of the world that any responsible government is bound to consider. The following note lists the major problems, attempts to assess their importance, and to suggest what lines may be relevant to Australia for their solution. These problems were examined because of the concern about the appropriateness of attempting to fulfill projected world energy needs by any means; and their fulfillment, by using nuclear fuels carries special problems of biological, social and political hazards. Any development of Australia's uranium resources should be considered in this light. (author)

    Directory of Open Access Journals (Sweden)

    Lenore Manderson

    2012-01-01

    Full Text Available Humanitarian immigrants and refugees face multiple adjustment tasks and post-settlement support services concentrated in metropolitan areas play an important role. As part of an ongoing commitment, the Australian Government has increasingly supported resettlement in rural and regional areas of the country. Drawing on the experience of Iraqi migrants in Victoria, Australia, we examine some of the conditions that characterize regional resettlement and raise key questions for public health policy. Structural vulnerabilities and discriminations impact upon physical, mental and social wellbeing, leading to further exclusion, with negative long-term implications. The discussion throws light on the issues that migrants and refugees may encounter in other parts within Australia, but are also germane in many countries and highlight the resulting complexity for policy-making.

  16. Migration of nurses in Australia: where and why?

    Science.gov (United States)

    Ohr, Se Ok; Parker, Vicki; Jeong, Sarah; Joyce, Terry

    2010-01-01

    The Australian health care workforce has benefited from an increasing migration of nurses over the past decades. The nursing profession is the largest single health profession, making up over half of the Australian health care workforce. Migration ofnurses into the Australian nursing workforce impacts significantly on the size ofthe workforce and the capacity to provide health care to the Australian multicultural community. Migration of nurses plays an important role in providing a solution to the ongoing challenges of workforce attraction and retention, hence an understanding of the factors contributing to nurse migration is important. This paper will critically analyse factors reported to impact on migration of nurses to Australia, in particular in relation to: (1) globalisation; (2) Australian society and nursing workforce; and (3) personal reasons. The current and potential implications of nurse migration are not limited to the Australian health care workforce, but also extend to political, socioeconomic and other aspects in Australia.

    International Nuclear Information System (INIS)

    Australia's uranium industry can be described as providing ''benefits for the many, concerns for the few''. This paper reviews the benefits which the development of uranium mining has brought - and could bring -to the nation in the form of economic reward. It then discusses the more complex question of the implications of that development for its more immediate locality - in particular for the environment and the Aboriginal people. Here too it is seen that the gains have been considerable and have been recognized by the Aboriginals themselves. Nonetheless, people remain concerned and their anxieties are considered in this paper. (author)

  7. Radiological terrorism and Australia's response

    International Nuclear Information System (INIS)

    A terrorist attack in Australia involving dispersal of radioactive material is different from conventional terrorist attacks involving explosives. The trauma experienced by victims during an explosive incident includes cuts, broken limbs, burns and shock. When an explosive device involving radioactive materials is involved, there are a number of additional characteristics including the contamination of victims and the surrounding area and the potential requirement for ongoing monitoring and decontamination. Response actions may require additional complex emergency response measures including immediate protective actions to protect those potentially exposed to contamination, mass casualty care, and public and mental health. There are concerns that terrorist organizations are showing increasing interest in acquiring radiological material that could be used with explosive. A dirty bomb or technically known as a radiological dispersal device (RDD) is a device designed to spread radioactive contamination over a wide area and pose a health and safety threat to those within the contaminated area. The radioactive material could be in the form of a large chunk of material, fine powder, a liquid mist, or a gas. The material may also be spread in other ways, such as by simply emptying a container over the desired area. As RDD's do not require large amounts of explosives, there is unlikely to be a large numbers of casualties, however the areas contaminated by the radiological material may cause immediate and long term health risks to those exposed. An RDD is a weapon of Mass Disruption rather than destruction. While the likelihood of RDD's being employed by terrorist in Australia is still considered remote, Australia's emergency response organizations are developing plans to ensure a rapid and comprehensive response occurs should such an event occur in this country, The presentation will outline Australia's response arrangements at the local/state level and the type of federal

  11. Australia: Approaching an energy crossroads

    International Nuclear Information System (INIS)

    This paper considers energy policy in Australia in the context of its considerable energy resources, climate change and a recent change in government. It examines the possible paths that future energy use and policy in Australia could take, including published projections based largely on a 'business as usual' approach and projections based on a dramatic shift towards more efficient use of energy and renewable energy technologies. It also considers the various factors affecting future policy direction, including energy security, the advocacy in Australia for establishing nuclear electricity generation and other parts of the nuclear fuel-cycle, responses to climate change, and carbon sequestration. It concludes that while the Australian Government is currently reluctant to move away from a dependence on coal, and unlikely to adopt nuclear energy generation, a low-emissions future without waiting for the deployment of carbon capture and storage and without resorting to nuclear power is within reach. However, in the face of strong pressure from interest groups associated with energy intensive industry, making the necessary innovations will require further growth of community concern about climate change, and the development of greater understanding of the feasibility of employing low carbon-emissions options.

  12. Karst and agriculture in Australia.

    Directory of Open Access Journals (Sweden)

    Gillieson David

    1999-01-01

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

    2016-01-01

    Dengue fever (DF) epidemics in Australia are caused by infected international travellers and confined to Northern Queensland where competent vectors exist. Recent analyses suggest that global trade and climate change could lead to the re-establishment of Ae. aegypti across the country and promote the spread of dengue nationally. This study aimed to describe the dynamic spatiotemporal trends of imported DF cases and their origins, identify the current and potential future high-risk regions and locate areas that might be at particular risk of dengue transmission should competent mosquito vectors expand their range. Our results showed that the geographical distribution of imported DF cases has significantly expanded in mainland Australia over the past decade. In recent years, the geographical distribution of source countries of DF has expanded from the Pacific region and Asia to include Africa and the Americas. Australia is now exposed to dengue importations from all of the regions involved in the current global pandemic. The public health implications of a range expansion of dengue mosquito vectors are severe. Enhanced mosquito surveillance in those areas that have high imported cases is called for to reduce emerging threats from this globally expanding pathogen. PMID:27460696

  14. COMMERCIAL SURROGACY: WHAT ROLE FOR LAW IN AUSTRALIA?

    Sifris, Ronli; Ludlow, Karinne; Sifris, Adiva

    2015-12-01

    This editorial begins by illuminating current conversations regarding the regulation of commercial surrogacy in Australia. It defines "commercial surrogacy" and explains the interaction between changes in social attitudes and changes to the law before setting out the current Australian law and practice in this area. An examination of current domestic law and practice reveals that surrogacy legislation in Australia is mired in inconsistencies and a lack of uniformity but that the one key common element is the prohibition of commercial surrogacy. The inability of couples to access commercial surrogacy within Australia has led to offshore reproductive tourism and unpredictable, contradictory decision-making as the Family Court attempts to apply legislation which was never intended to apply in this context. The editorial then turns to consider the international arena, discussing the approach of the Hague Conference on Private International Law before delving into a human rights analysis of commercial surrogacy arrangements. The adoption of a rights-based approach requires an analysis of this vexed issue from the perspective of the child, surrogate and intending parents. While questions surrounding the human rights implications of legalising commercial surrogacy continue to be the subject of passionate debate, the authors believe that the human rights of all parties are best protected through appropriate regulation rather than absolute prohibition.

    Allen, John T.; Allen, Edwina R.

    2016-09-01

    Severe thunderstorms are a common occurrence in Australia and have been documented since the first European settlement in 1788. These events are characterized by large damaging hail in excess of 2 cm, convective wind gusts greater than 90 km h- 1 and tornadoes, and contribute a quarter of all natural hazard-related losses in the country. This impact has lead to a growing body of research and insight into these events. In this article, the state of knowledge regarding their incidence, distribution, and the resulting hail, tornado, convective wind, and lightning risk will be reviewed. Applying this assessment of knowledge, the implications for forecasting, the warning process, and how these events may respond to climate change and variability will also be discussed. Based on this review, ongoing work in the field is outlined, and several potential avenues for future research and exploration are suggested. Most notably, the need for improved observational or proxy climatologies, the forecasting guidelines for tornadoes, and the need for a greater understanding of how severe thunderstorms respond to climate variability are highlighted.

  17. Indigenous community-based fisheries in Australia.

    2007-12-01

    The commercial sea cucumber species known as Sandfish (Holothuria scabra) occurs intertidally and subtidally in the Northern Territory of Australia, on or adjacent to Aboriginal land. A 4-yr program of community-based fisheries research with Aboriginal Australians was implemented to assess the viability of indigenous Australians' involvement in the wild-stock fishery. The research involved extensive and intensive indigenous participation, unusual in Australian biophysical sciences research, during field survey and habitat mapping, complemented by commercial catch data modelling and discussion of its implications. Field surveys produced Sandfish distribution and site-specific density, and revealed some areas that were not commercially fished. Catch data modelling results suggested that no additional effort could be sustained, however commercial fishers increased their effort, expanding their operations into the newly mapped areas. These actions effectively precluded indigenous peoples' aspirations of entry into the commercial fishery. The efficacy and outcomes of participatory program design with indigenous Australians need critique in the absence of the political will and statutory backing to provide equitable access to resources.

  19. The new energy technologies in Australia

    International Nuclear Information System (INIS)

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

  20. Recent developments in Australia's uranium mining industry

    International Nuclear Information System (INIS)

    Australia's economic, demonstrated resources of uranium (U) at the end of 1996 amounted to 622,000 tonnes U, the largest of any country. Uranium is currently produced at two mining/milling operations in Australia - Ranger in the Alligator Rivers Region of the Northern Territory, and Olympic Dam in South Australia. Improved market conditions and recent changes to Government policies have encouraged Australian companies to commit to the expansion of existing operations and the development of new uranium mines. Australia's annual production is likely to increase from its present level of 6000 tonncs (t) U3O8 to approximately 12 000 t U3O8 by the year 2000. (author)

  5. Uranium production economics in Australia

    International Nuclear Information System (INIS)

    This review of the economics of production of uranium in Australia provides a detailed description of eleven important uranium deposits including capital and production costs estimates and supply curves. For each mine a detailed assessment has been made of its potential production capacity to the year 2000. Socio-economic factors that play an all-too-important role in the Australian uranium industry are extensively reviewed to provide an insight into the factors affecting Australia's ability to supply. The study is based on a detailed computer-based economic engineering model where all major costs such as labor, consumables and capital recovery charges are analyzed for each mine, and levellised break-even prices determined. It is argued that at the present low market prices, the three on-going operations are profitable, and at least three other deposits could be brought to viable production, given the necessary Government approval. Several other deposits appear to be marginal at the set Australian export floor price of US$26 per pound. Annual production could be raised from about 6,000 tonnes of U3O8 to 16,000 tonnes by the turn of century, with the development of three additional deposits. It is concluded that, if Australian producers were allowed to compete freely on the international market, annual production would pass the 10,000 tonne/annum mark between 1995 and 2000. 35 figs., 38 tabs., 81 refs

  6. Neutron scattering science in Australia

    1999-10-01

    Neutron scattering science in Australia is making an impact on a number of fields in the scientific and industrial research communities. The unique properties of the neutron are being used to investigate problems in chemistry, materials science, physics, engineering and biology. The reactor HIFAR at the Australian Nuclear Science and Technology Organisation research laboratories is the only neutron source in Australia suitable for neutron scattering science. A suite of instruments provides a wide range of opportunities for the neutron scattering community that extends throughout universities, government and industrial research laboratories. Plans are in progress to replace the present research reactor with a modern multi-purpose research reactor to offer the most advanced neutron scattering facilities. The experimental and analysis equipment associated with a modern research reactor will permit the establishment of a national centre for world class neutron science research focussed on the structure and functioning of materials, industrial irradiations and analyses in support of Australian manufacturing, minerals, petrochemical, pharmaceuticals and information science industries.

    2014-03-01

    The National Notifiable Diseases Surveillance System received 1,353 tuberculosis (TB) notifications in 2010, representing a rate of 6.1 cases per 100,000 population. While rates of 5 to 6 cases per 100,000 population for TB have been maintained in Australia, since first achieved in the mid-1980s, there has been a steady increase in incidence over the past decade. The incidence in the Australian-born Indigenous population was 7.5 per 100,000 population, which is 11 times the incidence reported in the Australian-born non-Indigenous population of 0.7 per 100,000 population. Overseas-born people accounted for 90% of all cases notified in 2010 and represented a rate of 24 per 100,000 population. International students have been recognised as an increasingly important group, representing 25% of all overseas-born cases notified in 2010, and are a focus of this report. Household or other close contact with TB or past residence in a high risk country were the most commonly reported risk factors for TB infection. Outcome data for the 2009 TB cohort indicate that treatment success was attained in more than 95% of cases. As Australia continues to contribute to global TB control it is important to maintain good centralised national reporting of TB to identify populations at risk and monitor trends in TB.

    1994-08-01

    The paper reviews the published vehicle safety ratings based on mass crash data from the United States, Sweden, and Great Britain. It then describes the development of vehicle crashworthiness ratings based on injury compensation claims and police accident reports from Victoria and New South Wales, the two most populous states in Australia. Crashworthiness was measured by a combination of injury severity (of injured drivers) and injury risk (of drivers involved in crashes). Injury severity was based on 22,600 drivers injured in crashes in the two states. Injury risk was based on 70,900 drivers in New South Wales involved in crashes after which a vehicle was towed away. Injury risk measured in this way was compared with the "relative injury risk" of particular model cars involved in two car crashes in Victoria (where essentially only casualty crashes are reported), which was based on the method developed by Folksam Insurance in Sweden from Evans' double-pair comparison method. The results include crashworthiness ratings for the makes and models crashing in Australia in sufficient numbers to measure their crash performance adequately. The ratings were normalised for the driver sex and speed limit at the crash location, the two factors found to be strongly related to injury risk and/or severity and to vary substantially across makes and models of Australian crash-involved cars. This allows differences in crashworthiness of individual models to be seen, uncontaminated by major crash exposure differences. PMID:7916859

    2013-11-01

    Psittacid herpesvirus 3 (PsHV-3) has recently been implicated as the cause of a severe respiratory disease in Bourke's parrots (Neopsephotus bourkii) in the United States. In this report, the clinical manifestations and gross and microscopic lesions of PsHV-3 infection in 2 eclectus parrots (Eclectus roratus) in Australia are described. The presence of a PsHV-3 infection was confirmed by polymerase chain reaction amplification and sequencing of PsHV-3 DNA using degenerate and PsHV-3 primers. Electron microscopy of infected cells demonstrated the assembly of herpesvirus virions as well as intranuclear tubular structures. The detection of PsHV-3 in Australia in 2 eclectus parrots broadens the list of known affected species and confirms the presence of this virus in Australia. PMID:23697483

  15. Uranium exploration and mining in Australia

    International Nuclear Information System (INIS)

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

  16. Atomic test site (south Australia)

    International Nuclear Information System (INIS)

    The debate, which lasted about half an hour, is reported verbatin. It was prompted by the campaign by the Maralinga people of South Australia to have their traditional lands restored to them. Between 1953 and 1957 the United Kingdom government carried out of atomic tests and several hundred minor trials on the lands. A clean-up programme had taken place in 1967 but further decontamination was needed before the area is safe for traditional aboriginal life and culture. A small area will remain contaminated with plutonium for thousands of years. The cost and who would pay, the Australian or UK government was being negotiated. The UK government's position was that the site is remote, the health risk is slight and the clean-up operation of 1967 was acknowledged as satisfactory by the Australian government. (UK)

    2013-03-01

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

  19. Replacement research reactor for Australia

    International Nuclear Information System (INIS)

    In 1992, the Australian Government commissioned a review into the need for a replacement research reactor. That review concluded that in about years, if certain conditions were met, the Government could make a decision in favour of a replacement reactor. A major milestone was achieved when, on 3 September 1997, the Australian Government announced the construction of a replacement research reactor at the site of Australia's existing research reactor HIFAR, subject to the satisfactory outcome of an environmental assessment process. The reactor will be have the dual purpose of providing a first class facility for neutron beam research as well as providing irradiation facilities for both medical isotope production and commercial irradiations. The project is scheduled for completion before the end of 2005. (author)

    I recently watched a fascinating documentary about the crusade of Dr Bertram Wainer in the 1960s to bring the practice of illegal abortion in Victoria to an end. It documented the profound horror of the backyard abortion that so often ended in infection, sterility or death, and served as a potent reminder of a practice to which we must never return. Of course that cant happen again, abortion is legal now, isnt it? In Victoria in 1969 a Supreme Court judge ruled that an abortion is not unlawful if a doctor believed that: the abortion is necessary to preserve the woman from serious danger to her life or physical or mental health (Menhennit ruling). In Australia today however, abortion law remains conditional, unclear and inconsistent and, except in the ACT, is still part of criminal statutes. PMID:16969440

    Full Text Available The aim of this paper is to document agricultural innovation systems (AIS in Australia. We identified eleven broad categories (actors in terms of their activities, namely: policy, education, finance and credit, marketing, input supply, research, extension and information, logistics, processing and storage, farmers and farm organisations and consumers. Survey results reveal that 11 kinds of innovation-related activities of research and education organisations with corresponding percentage weight are directly involved in innovation diffusion. Twelve pre-identified goals of innovation related activities of the above organisations surveyed with their corresponding percentage weight have also been revealed. The study reveals that the majority of funding (more than 80% for innovation activities comes from the Federal Government and funding bodies. Finally survey results indicate that the main constrains/incentives are other issues such as funding, lack of qualified staff, equipment, environmental and Government policy issues etc.

    2011-02-21

    In recent years, a phenomenon of "late effects of the Holocaust" has emerged, with impacts on the psychological and physical health of ageing Holocaust survivors. As Holocaust survivors age, they may experience heightened anxiety around normal processes of ageing, worsened post-traumatic stress disorder with cognitive decline, and fear of the medical system. Holocaust survivors are at increased risk of osteoporosis, cardiometabolic disease due to hypothalamic-pituitary-adrenal axis dysfunction, cancer, and sequelae of Nazi medical experiments. From existing medical literature on this topic, practical principles of management are derived to create a framework for sensitive medical management of Holocaust survivors in Australia. The issues discussed are also relevant to the wider geriatric refugee or prisoner-of-war experience. PMID:21401461

  3. A Depletion Protocol for Non-Renewable Natural Resources: Australia as an Example

    International Nuclear Information System (INIS)

    This paper examines the implications of statements by Australia's Minister of Resources that Australia's exports of coal are growing rapidly and that Australia's coal will last '110 years at current rates of production.' If one assumes that coal production P(t), follows a Gaussian curve (similar to a Hubbert curve) one can construct a family of Gaussian curves showing possible future paths of P(t) which are consistent with the cited '110 years.' Each curve reaches a maximum after which P(t) declines toward zero. Knowledge of the present value of dP/dt allows one member of the family to be identified as the most probable future path of P(t). Families of curves and tabular data are presented for resource quantities that would last 50, 100 and 200 years 'at current rates of production.' If, instead, Australia's P(t) follows a declining exponential curve (exp(-kt)) with k = (1/110) per year, the stated quantity of coal will allow production to continue forever, with P(t) declining with a half life of 76 y. This and more rapidly declining exponential paths are the only paths that can be said to be sustainable. The envelope of the family of Gaussian curves divides the (P, t) plane into 'allowed' and 'forbidden' areas. The declining exponential curve divides the 'allowed' area into an upper area that is 'terminal' and a lower area that is 'sustainable.' These facts, coupled with Australia's expectations of rapid growth of its population, suggest that Australia's present resource policies are 'anti-sustainable' and that the people of Australia need to rethink their present policy of rapidly exporting their fossil fuels

    Objectives To estimate the proportion and numbers of cancers occurring in Australia attributable to solar ultraviolet radiation (UVR) and the proportion and numbers prevented by regular sun protection factor (SPF) 15+ sunscreen use. Methods We estimated the population attributable fraction (PAF) and numbers of melanomas and keratinocyte cancers (i.e. basal cell carcinomas and squamous cell carcinomas) due to exposure to ambient UVR resulting from residing in Australia versus residing in the UK (for melanoma) or Scandinavia (for keratinocyte cancers). We also estimated the prevented fraction (PF): the proportion of cancers that would have occurred but were likely prevented by regular sunscreen use. Results An estimated 7,220 melanomas (PAF 63%) and essentially all keratinocyte cancers occurring in Australia were attributable to high ambient UVR levels in Australia. We estimated that regular sunscreen use prevented around 14,190 (PF 9.3%) and 1,730 (PF 14%) people from developing SCC and melanoma, respectively. Conclusions Although our approach was conservative, a high proportion of skin cancers in Australia are attributable to high ambient levels of UVR. Prevailing levels of sunscreen use probably reduced skin cancer incidence by 10–15%. Implications Most skin cancers are preventable. Sunscreen should be a component of a comprehensive sun protection strategy. PMID:26437734

    This edition of Oil and Australia summarises the industry's forecasts of demand for petroleum products to the year 2004 and estimates the extent to which demand can be met from domestic production of crude oil, condensate and naturally occurring liquefied petroleum gas (LPG). The demand forecasts represent the average of forecasts prepared for forward planning purposes, of the five refining and marketing company members of the Australian Institute of Petroleum Ltd - Ampol Ltd, BP Australia Limited, Caltex Australia Limited, Mobil Oil Australia Ltd and The Shell Company of Australia Limited. The assumptions underlying the forecasts are also presented. The forecasts are a long term, directional view and assume no major policy changes will occur over the forecast period. A section on natural gas is included to provide a broader picture of the outlook for hydrocarbon energy needs, supply and export potential for Australia. natural gas is an important and growing energy source, and provides an opportunity for Australia to increase its exports and improve its balance of payments situation. 26 tabs., 14 figs

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

    Introduction Many refugees arrive in Australia with complex health needs. In South Australia (SA), providing initial health care to refugees is the responsibility of General Practitioners (GPs) in private practice. Their capacity to perform this work effectively for current newly arrived refugees is uncertain. The aim of this study was to document the challenges faced by GPs in private practice in SA when providing initial care to refugees and to discuss the implications of this for policy re...

    Climate change is a highly contested policy issue in Australia, generating fierce debate at every level of governance. In this paper we explore a crucial tension in both the policy and the public debate: a seeming lack of attention to social inclusion and broader equity implications. We pay special attention to the municipal scale, where concerns about social difference and democratic participation are often foregrounded in political discourse, using South East Queensland—a recognised climate...

  11. New research reactor for Australia

    International Nuclear Information System (INIS)

    HIFAR, Australia's major research reactor was commissioned in 1958 to test materials for an envisaged indigenous nuclear power industry. HIFAR is a Dido type reactor which is operated at 10 MW. With the decision in the early 1970's not to proceed to nuclear power, HIFAR was adapted to other uses and has served Australia well as a base for national nuclear competence; as a national facility for neutron scattering/beam research; as a source of radioisotopes for medical diagnosis and treatment; and as a source of export revenue from the neutron transmutation doping of silicon for the semiconductor industry. However, all of HIFAR's capabilities are becoming less than optimum by world and regional standards. Neutron beam facilities have been overtaken on the world scene by research reactors with increased neutron fluxes, cold sources, and improved beams and neutron guides. Radioisotope production capabilities, while adequate to meet Australia's needs, cannot be easily expanded to tap the growing world market in radiopharmaceuticals. Similarly, neutron transmutation doped silicon production, and export income from it, is limited at a time when the world market for this material is expanding. ANSTO has therefore embarked on a program to replace HIFAR with a new multi-purpose national facility for nuclear research and technology in the form of a reactor: a) for neutron beam research, - with a peak thermal flux of the order of three times higher than that from HIFAR, - with a cold neutron source, guides and beam hall, b) that has radioisotope production facilities that are as good as, or better than, those in HIFAR, c) that maximizes the potential for commercial irradiations to offset facility operating costs, d) that maximizes flexibility to accommodate variations in user requirements during the life of the facility. ANSTO's case for the new research reactor received significant support earlier this month with the tabling in Parliament of a report by the Australian Science

  12. Tele-dermatology in Australia.

    Muir, Jim; Lucas, Lex

    2008-01-01

    Australia is a large country with a small and scattered population. Specialist dermatology services are concentrated in the capital cities and larger urban centers on the coast. This has meant access to these services for Australians in rural and remote areas has been limited to those able to travel the often long distances to their nearest dermatologist. Due to a considerable shortage of dermatologists, waiting times to see one are more than six months. The challenge was to provide a dermatology service that overcame these twin obstacles of distance and demand. Telecommunication infrastructure in Australia is good and most towns have at least one general practitioner. More than 75% of all general practices are equipped with computers and have broadband internet access.Dermatology is a specialty with few life threatening disorders. However short delays in diagnosis and management of a skin condition rarely have any serious impact on a patient's long-term health. At the same time many skin problems are distressing, and difficult to diagnose and treat. Many skin conditions last for considerable periods of time and patients need ongoing care. Due to the highly visual nature of the specialty, most skin conditions can be diagnosed from an image especially if there is some history available. This often requires a trained specialist. Paradoxically, any needed investigations such as skin biopsy or blood tests can be performed by any qualified doctor. Dermatological treatments can be instituted and monitored by these same practitioners without any specialist training. These factors make tele-medicine an ideal solution to the problems of isolation from and excess demand for specialist dermatological services. In 2004 the Australian College of Rural and Remote Medicine (ACRRM) in a joint initiative with Queensland Divisions of General Practice (QDGP) set up Tele-Derm with funding from the Commonwealth Department of Health and Ageing under the Medical Specialist Outreach

  15. Renewable energy development and prospects in Australia

    International Nuclear Information System (INIS)

    Development of renewable energies in Australia is still in its infancy and will require active support by government, utilities and financing institutions to ensure a steady growth. Much has been done to increase the utilisation of renewable energies in the energy supply, but much still remains to be done, especially in the areas of promotion, demonstration, training and technology transfer. This process will lead to meeting the energy needs of the population in rural areas and to contributing to a suitable development of the region during the next century. Australia is endowed with a wealth of renewable energy resources that hold great promise for addressing a host of important environmental, employment and socioeconomic issues. Australia has a set of climate, geographic and other factors that provide favourable conditions for many specific renewable energy applications. The objectives of this paper is to look at the current situation of renewable energies in Australia, opportunities, constraints, current projects, available potential and future prospects. (Author)

  16. Climate change and wind power in Australia

    International Nuclear Information System (INIS)

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

  19. Industrial Radiography Safety in Australia

    International Nuclear Information System (INIS)

    cumbersome and often exceeds the prescribed OH and S single person lifting limits. The role of industrial radiography has expanded to inspect not only welds and castings, so that it now includes inspection of assembled and processed goods ranging from automotive air-bags to canned food. It is also used in security systems at airports and other facilities. Almost all these applications use cabinet systems which are rarely the subject of serious radiation incidents or accidents. Gamma ray inspection no longer uses radium. The most common radio-isotopes in use now are Cobalt 60 and Iridium 192. Their freedom from the need for an electrical power supply; their high radiation energy and the ability to place a source in positions of limited physical access, ensures the ongoing attraction of the method. The useful activity ranges of typical sources vary according to their application and the effect on total inspection costs. Common source activities in Australia range between 185 and 370 GBq for Cobalt 60; and between 1500 and 3700 GBq for Iridium 192. Outside Australia however there are recent reports of routine industrial radiography using more than 5500 GBq of Iridium 192. Thus it can be appreciated that any radiation accidents involving these high activity sources have the potential for significant radiation doses. Personal Dose Data: ARPANSA and its predecessor, the Australian Radiation Laboratory, has been providing a personal radiation monitoring service for some time, and releases a summary report every few years (ARPANSA/TR 139, ARL/TR 121, ARL/TR 107). The selected data shown in Table 2 indicate a downward trend in occupational doses received by industrial radiographers working in open site situations, which are potentially the most hazardous. This trend is encouraging, especially when the number of industrial radiographers is increasing. A comparison of the ARPANSA data indicate that whilst the average Australian industrial radiographer's annual dose is higher than the

  20. Uranium Processing Research in Australia

    International Nuclear Information System (INIS)

    Uranium processing research in Australia has included studies of flotation, magnetic separation, gravity separation, heavy medium separation, atmospheric leaching, multi-stage leaching, alkali leaching, solar heating of leach pulps, jigged-bed resin-in-pulp and solvent-in-pulp extraction. Brief details of the results obtained are given. In general, it can be said that gravity, magnetic and flotation methods are of limited usefulness in the treatment of Australian uranium ores. Alkali leaching seldom gives satisfactory recoveries and multi-stage leaching is expensive. Jigged-bed resin-in-pulp and packed tower solvent-in-pulp extraction systems both show promise, but plant-scale development work is required. Bacterial leaching may be useful in the case of certain lowgrade ores. The main difficulties to be overcome, either singly or in combination, in the case of Australian uranium ores not currently considered economically exploitable, are the extremely finely divided state of the uranium mineral, the refractory nature of the uranium mineral and adverse effects due to the gangue minerals present. With respect to known low-grade ores, it would be possible in only a few cases to achieve satisfactory recovery of uranium at reasonable cost by standard treatment methods. (author)

  1. Immigration in two federations: Canada and Australia.

    Science.gov (United States)

    Atchison, J

    1988-03-01

    The need for increasingly widespread application of a policy or program, settlement, and multiculturalism is urgent in both Canada and Australia. For both countries there is a clear pattern of coalescence and divergence and the distinct growth of immigration as a federal function. While Australia has strengthened federal functions in a area of increasingly geo-political need, Canada is moving towards a looser model of federalism. By 1918 both countries were strengthening their federal functions in immigration as discussions within the British Empire on the recommendations of the 1917 Dominions Royal Commission took root. Both countries were interested in agricultural immigration and land settlement. The Great Depression caused a major reduction in population growth rates. From 1933-1948 Canada had a poor record of providing sanctuary for Jews. In Australia, however, Jewish voluntary agencies were aiding the reception of refugees by 1937. The 1st permanent embodiment of commonwealth jurisdiction over immigration was the establishment of an Immigration Branch within the Department of Interior around 1938. Australia needed extra population for defense. The major structural link between government and the immigrant communities was through the Good Neighbor Movement, which began on a nationwide basis in 1950. Both Canada and Australia are major receiving countries for refugees. In 1973 Australia reached the position of effective, practical nondiscrimination achieved by Canada in 1967. Prime Minister Trudeau's policy was multiculturalism within a framework of bilingualism. By 1978 Australia had a new federalism policy, which in all areas concerned with immigrants, refugees and ethnicity, rationalized resources allocation and imposed a political philosophy. The foci of multiculturalism in Australia are 1) community languages; 2) creation of a tolerant, non-discriminatory society; and 3) equity and participation. In 1978 Australia specified population replacement and

  3. The renewable energy market in Australia

    International Nuclear Information System (INIS)

    Australia is committed to an 8 per cent reduction in its emissions of greenhouse gases above 1990 levels as a result of the Kyoto Protocol for the period 2008-2012. At present, the emissions stand at 17.4 per cent above 1990 levels. Total electrical power in Australia resulting from renewable energy is in the order of 10.5 per cent. A mandatory renewable energy target of 9500 gigawatt hour (GWh) of extra renewable energy is to be produced annually by 2010, under the Renewable Energy (Electricity) Act. An emissions trading system has been implemented, involving one renewable energy certificate (REC) created for each megawatt hour of renewable energy generated. A significant expansion of the demand for renewable energy is expected in Australia over the next ten years, according to the Australian Greenhouse Office. Increased opportunities for local and international firms operating in the field of renewable energy are being created by the Australian government through initiatives such as the Renewable Energy Commercialization Program, and the Renewable Remote Power Generation Program. Solar, biomass, and wind power are comprised in the wealth of renewable energy resources in Australia. The market remains largely undeveloped. Firms from the United States and the European Union are the leading exporters of renewable energy technology to Australia. Public utilities and independent power producers having entered the deregulated electricity market are the consumers of renewable energy technology and services. A country with minimal duties in most cases, Australia has much in common with Canada, including similar regulatory and legal systems. Australia applies a 10 per cent goods and services tax, which would apply to Canadian exports. It was advised to consult the Australian Customs Service for additional information concerning duties that might be applicable to the renewable energy industry. 28 refs., 3 tabs

  4. Perceived Challenges in Dementia Care by Vietnamese Family Caregivers and Care Workers in South Australia.

    2015-09-01

    The majority of Vietnamese Australians migrated to Australia as refugees to escape a war and this unique migration background may affect their ability to access and utilize healthcare services in Australia. Inability to utilize dementia services is associated with higher levels of caregiver burden, higher rates of morbidities and mortality and hospitalization. The aim of the study was to explore the perceived challenges of dementia care from Vietnamese family caregivers and Vietnamese care workers. Gadamer's philosophical hermeneutics was used to interpret and describe the experiences of the participants. Data were collected from in-depth interviews with six Vietnamese family caregivers and a focus group with Vietnamese care workers using purposive sampling. Participants were recruited from a Vietnamese community care organization in South Australia. Five themes were identified from the data analysis namely: (1) a need for culturally and linguistically appropriate dementia education programs; (2) a willingness and unwillingness to seek help; (3) poor knowledge of health care service availability related to dementia; (4) the effect of language barrier in accessing services; and (5) the main sources of services utilized. The study revealed that Vietnamese family caregivers and Vietnamese care workers held different views on the association of stigma with dementia. Findings also revealed factors that impacted accessing and utilizing dementia services. These findings facilitate a more comprehensive understanding of Vietnamese family caregivers' needs and have implications for developing individualized support for family caregivers and for consumer-directed dementia services in Australia.

    Given international concerns about students' pursuit (or more correctly, non-pursuit) of courses and careers in science, technology, engineering and mathematics, this study is about achieving a better understanding of factors related to high school students' engagement in science. The study builds on previous secondary analyses of Programme for International Student Assessment (PISA) datasets for New Zealand and Australia. For the current study, we compared patterns of science engagement and science literacy for male and female students in Canada and Australia. The study's secondary analysis revealed that for all PISA measures included under the conceptual umbrella of engagement in science (i.e. interest, enjoyment, valuing, self-efficacy, self-concept and motivation), 15-year-old students in Australia lagged their Canadian counterparts to varying, albeit modest, degrees. Our retrospective analysis further shows, however, that gender equity in science engagement and science literacy is evident in both Canadian and Australian contexts. Additionally, and consistent with our previous findings for indigenous and non-indigenous students in New Zealand and Australia, we found that for male and female students in both countries, the factor most strongly associated with variations in engagement in science was the extent to which students participate in science activities outside of school. In contrast, and again for both Canadian and Australian students, the factors most strongly associated with science literacy were students' socioeconomic backgrounds, and the amount of formal time spent doing science. The implications of these results for science educators and researchers are discussed.

  7. Australia's replacement research reactor project

    International Nuclear Information System (INIS)

    HIFAR, a 10 MW tank type DIDO Class reactor has operated at the Lucas Heights Science and Technology Centre for 43 years. HIFAR and the 10 kW Argonaut reactor 'Moata' which is in the Care and Maintenance phase of decommissioning are Australia's only nuclear reactors. The initial purpose for HIFAR was for materials testing to support a nuclear power program. Changing community attitude through the 1970's and a Government decision not to proceed with a planned nuclear power reactor resulted in a reduction of materials testing activities and a greater emphasis being placed on neutron beam research and the production of radioisotopes, particularly for medical purposes. HIFAR is not fully capable of satisfying the expected increase in demand for medical radiopharmaceuticals beyond the next 5 years and the radial configuration of the beam tubes severely restricts the scope and efficiency of neutron beam research. In 1997 the Australian Government decided that a replacement research reactor should be built by the Australian Nuclear Science and Technology Organisation at Lucas Heights subject to favourable results of an Environmental Impact Study. The Ei identified no reasons on the grounds of safety, health, hazard or risk to prevent construction on the preferred site and it was decided in May 1999 that there were no environmental reasons why construction of the facility should not proceed. In recent years ANSTO has been reviewing the operation of HIFAR and observing international developments in reactor technology. Limitations in the flexibility and efficiency achievable in operation of a tank type reactor and the higher intrinsic safety sought in fundamental design resulted in an early decision that the replacement reactor must be a pool type having cleaner and higher intensity tangential neutron beams of wider energy range than those available from HIFAR. ANSTO has chosen to use it's own resources supported by specialised external knowledge and experience to identify

    1995-11-01

    Despite having almost the highest rate of population growth among OECD countries, Australia has no explicit population policy. The potential elements of such a policy, especially with regard to immigration, family, and environment, are deeply entrenched in separate political domains and responsive to separate clusters of interests. Vague, demographically ill-informed, and mutually inconsistent views of a desired population size or trajectory for Australia co-exist, with no arena for any systematic engagement and considered debate among them. Parallels to the case of Australia can be drawn with Canada and the US. Population policy may well be one of the issues that modern liberal democracies find particularly difficult to manage. There are, however, also specific historical circumstances which led to the outcome and perpetuate the situation. Population processes and the institution of citizenship, and contested policy domains are discussed. PMID:12321981

    With consultations having been held across Australia this year as part of the process of developing a new National Alcohol Strategy, it seemed timely to invite my colleagues from the National Drug Research Institute who are experts in the alcohol field to write this Harm Reduction Digest. The authors have canvassed a range of alcohol policy options and discussed their effectiveness in reducing harm for what is arguably Australia's number one drug problem. Australia's response to alcohol and other drug problems has, historically, been based on 'harm minimization--incorporating supply reduction, demand reduction and harm reduction'. At this time where the policy options for alcohol are being set for the next 5 years in a climate of 'small government', removing restrictions of 'fair competition' in business and a belief in the free market, what does the research have to say about recommended policies and strategies to reduce alcohol-related harm?

  10. Australia's uranium - greenhouse friendly fuel for an energy hungry world: a case study into the strategic importance of Australia's uranium resources for the inquiry into developing Australia's non-fossil fuel energy industry

    International Nuclear Information System (INIS)

    The terms of reference for the case study were to inquire into and report on the strategic importance of Australia's uranium resources. The Committee was asked to give particular attention to the: global demand for Australia's uranium resources and associated supply issues; potential implications for global greenhouse emission reductions from the further development and export of Australia's uranium resources; and the current regulatory environment of the uranium mining sector. The Committee indicated in its letters inviting submissions that it would also welcome comments in relation to six additional issues, relating to: whole of life cycle waste management; adequacy of social impact assessment, consultation and approval processes with traditional owners; health risks to workers and to the public from exposure to radiation; adequacy of regulation of uranium mining by the Commonwealth; the extent of federal subsidies and other mechanisms to facilitate uranium mining; and the effectiveness of safeguards regimes in addressing proliferation. These matters are addressed in the Committee's report, which consists of 12 chapters. The contents, findings and recommendations of each chapter are summarised as follows. The Committee's conclusions and recommendations are also summarised in a key messages section at the beginning of each chapter and in the conclusions section at the end of each chapter

    Paleoclimate research indicates that the instrumental climate record (~100 years in Australia) does not cover the full range of hydroclimatic variability possible. To better understand the implications of this for catchment-scale water resources management, an annual rainfall reconstruction is produced for the Williams River catchment in coastal eastern Australia. No high resolution palaeoclimate proxies are located in the region and so a teleconnection between summer sea salt deposition recorded in ice cores from East Antarctica and rainfall variability in eastern Australia was exploited to reconstruct 1013 years of rainfall (AD 1000-2012). The reconstruction shows that significantly longer and more frequent wet and dry periods were experienced in the preinstrumental compared to the instrumental period. This suggests that existing drought and flood risk assessments underestimate the true risks due to the reliance on data and statistics obtained from only the instrumental record. This raises questions about the robustness of existing water security and flood protection measures and has serious implications for water resources management, infrastructure design, and catchment planning. The method used in this proof of concept study is transferable and enables similar insights into the true risk of flood/drought to be gained for other locations that are teleconnected to East Antarctica. This will lead to improved understanding and ability to deal with the impacts of multidecadal to centennial hydroclimatic variability.

    The status of women in physics is Australia has remained mostly steady until recently, with the appointment of several eminent women in major government of public roles. Australia seems to maintain the same gender ratio for those studying and working in physics. There is no overall coordination of programs to assist women into the workplace but there is generally goodwill. Success in attracting and retaining women in the physics workforce appears to depend on the local culture, initiatives, and attitude of the most senior person in the organization.

  17. Roaming yuppies: Hong Kong migration to Australia.

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

    Australia and New Zealand share in part a history in the Gondwana supercontinent. Australia has a long and complex tectonic history with the last major accretion in the early Paleozoic, whereas New Zealand is still undergoing major plate boundary processes. The Australian continent is relatively well covered with both active and passive seismic techniques. Multiple sources of information are therefore available for building a model of Moho depth. Results from on-shore and off-shore refraction experiments are supplemented by receiver functions from a large number of portable stations and the recently augmented set of permanent stations. Moho picks from more than 10 500 km of full-crustal reflection profiles provide valuable additional constraints. The composite data set provides good sampling of much of Australia, though coverage remains low in some remote desert areas. The various datasets provide multiple estimates of the depth to Moho in many regions, and the consistency between the different techniques is high. Some of the thinnest crust lies beneath the Archean craton in the Pilbara, and in the neighbourhood of the Simpson desert. Thick crust is encountered beneath parts of the Proterozoic in Central Australia, and beneath the Paleozoic Lachlan fold belt in southeastern Australia. There are a number of zones of sharp contrast in depth to Moho, notably in the southern part of Central Australia. Despite most of the continental material around New Zealand being submerged, Moho data for this region is mainly onshore concentrating on the Australia-Pacific plate boundary. Two major wide-angle reflection transects provide the bulk of the active source data with just a few traditional reflection profiles offshore. The plate boundary provides an abundance of local earthquakes for tomographic imaging and this data is supplemented with receiver functions from both portable and permanent networks. Onshore the combined coverage is as dense as that of Australia, although it

  2. Uranium exploration in Australia: A renewed interest

    International Nuclear Information System (INIS)

    Australia contains the world's largest resources in the US$80/kg U Reasonably Assured Resources (RAR) category. Recently, interest for uranium in Australia has been piqued, largely as a result of the increase in the world's demand for uranium product. However, the renewed interest is also as a result of local influences such as a more balanced assessment of the nuclear industry by some legislators, commentators and the public at large. The increase in the uranium price also has obvious financial incentives for discovering a new uranium deposit (or re-invigorating a dormant resource) resulting in a number of new uranium explorers recently appearing on the Australian market and the inclusion of the commodity into established companies portfolios. During the past decade, a large proportion of annual uranium exploration expenditure has been focussed on discovering Ranger or Jabiluka equivalents. Two methods that have greatly assisted exploration teams have been airborne electromagnetic (Tempest+T+M) and airborne gravity gradiometer (Falcon+T+M) surveys. Another regional exploration tool trialled with limited success, but with obvious potential, has been airborne hyperspectral surveying. Exploration for this style of mineralisation has historically been centred on western Arnhem Land. While this area remains a major focus, attention is also shifting towards other Proterozoic basins in South Australia and Western Australia that have experienced limited exploration during the 1970's and 1980's, and where the potential for hosting significant deposits is largely untested. The commencement of production at Beverley in 2000 and the feasibility studies at the Honeymoon and Gould's Dam projects has seen a marked increase in exploration activity in the Curnamona Province, eastern South Australia for sediment-hosted uranium deposits amenable to in-situ leaching extraction. Areas of focus for sediment-hosted mineralisation are the Callabonna sub-basin, which contains the Beverley

    Full Text Available This study introduces Net Export (NX models to examine the determinants of the trade flows between Australia and eight selected trading partner (TP countries (China, France, Germany, Malaysia, Singapore, Thailand, United Kingdom, United States of America in four selected Trade Deficit (TD categories (Pharmaceutical Products; Nuclear Reactors, Boilers, Machinery and Mechanical Appliances; Electrical Machinery and Equipment; Sound Recorders and Producers, and Vehicles Other Than Railway or Tramway Rolling-Stock. A total of 29 NX models are estimated, which are based on both the monetary and Quantity (QTY values. Findings in this study suggest that macroeconomic variables such as money supply, interest rates and savings rates have no-significant effect in the determination of the NX levels in the selected categories. This highlights that monetary policy cannot influence the NX levels in the selected TD categories in Australia. This study also identifies some policy implications which arise from this paper.

  4. Social acceptance of wind energy development and planning in rural communities of Australia: A consumer analysis

    International Nuclear Information System (INIS)

    Social acceptance is necessary for widespread adoption of new renewable energy technologies. A lack of social acceptance by local community residents is a barrier to increasing the renewable energy mix and targets in Australia. This study empirically evaluated predictor importance of key constructs of social acceptance, using responses from a sample of 226 survey respondents in Australia. Regression analysis suggest that ‘Concerns with wind turbines’ was the predictor most strongly correlated with Social Acceptance, followed by ‘Annoyance with wind turbines’, and then ‘Consultation with stakeholders’. Implications of the study and recommendations for consideration by various interest groups (such as policy makers, and potential entrepreneurs) are discussed. This research contributes to theory building rather than theory testing of social acceptance of wind energy development

    2003-06-01

    Grape phylloxera, Daktulosphaira vitifoliae Fitch, is an important pest of grapevines (Vitis vinifera L.) (Vitaceae). Using microsatellite DNA markers it was demonstrated strong associations can exist between D. vitifoliae asexual lineages and vine host type within a vineyard. Also, in excised root bioassays, D. vitifoliae collected from three regions where different genotypic classes predominated showed host-specific differences in life table parameters of reproductive rate and intrinsic rate of increase. Lastly, comparisons of mitochondrial DNA (cytochrome oxidase I) sequences revealed that D. vitifoliae in Australia have paraphyletic origins and fall into two clades partially related to vine host usage. These findings indicate introduction of separate lineages of D. vitifoliae which have close host associations and as such, have important implications for management of this pest in Australia.

  12. Radiation doses from computed tomography in Australia

    International Nuclear Information System (INIS)

    Recent surveys in various countries have shown that computed tomography (CT) is a significant and growing contributor to the radiation dose from diagnostic radiology. Australia, with 332 CT scanners (18 per million people), is well endowed with CT equipment compared to European countries (6 to 13 per million people). Only Japan, with 8500 units (78 per million people), has a significantly higher proportion of CT scanners. In view of this, a survey of CT facilities, frequency of examinations, techniques and patient doses has been performed in Australia. It is estimated that there are 1 million CT examinations in Australia each year, resulting in a collective effective dose of 7000 Sv and a per caput dose of 0.39 mSv. This per caput dose is much larger than found in earlier studies in the UK and New Zealand but is less than 0.48 mSv in Japan. Using the ICRP risk factors, radiation doses from CT could be inducing about 280 fatal cancers per year in Australia. CT is therefore a significant, if not the major, single contributor to radiation doses and possible risk from diagnostic radiology. (authors)

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

  20. Uranium mining in Canada and Australia

    International Nuclear Information System (INIS)

    This study compared the impact of taxation on the economic viability and competitive position of uranium mining in Canada and Australia. The evaluation is based on four types of uranium deposit and four hypothetical project models. The deposits are assumed to have been discovered and delineated, and are awaiting a mine development decision. The models, initially appraised on a before-tax basis, are then subjected to taxation in each of six jurisdictions. Several taxation criteria are assessed in each case, including after-tax measures of investment incentive, discounted tax revenues, effective tax rates, intergovernmental tax shares, and comparative tax levels. The impact of taxation is shown to be both high and variable. The taxation systems in Saskatchewan and Australia's Northern Territory generate the most government revenue and provide the lowest incentive for investment. Canada's Northwest Territories and Ontario provide the best investment incentive and collect the least amount of taxes. South Australia and Western Australia tend to be positioned between these extremes. The study demonstrates that only the very best uranium mining projects have a chance of being developed under current market conditions, and even these can be rendered uneconomic by excessive taxation regimes. It follows that exceptionally good quality targets will have to be identified to provide the economic justification for uranium exploration. These realities will likely restrict uranium exploration and development activities for some time, not an unexpected response to a market situation where low prices have been caused largely by excess supply.

    2016-06-01

    Liver transplantation (LT) in Australia and New Zealand began in 1985. Over this time until December 2014, LT took place in 3700 adults and 800 children. LT is regulated with 1 unit, supported by the government, per state or region. Currently approximately 270 transplants take place per year. Organ donation rates are moderate in Australia (17 per 1 million of population) but very low in New Zealand (11 per 1 million of population). All the units share organ donors for fulminant hepatic failure cases (status 1). Recipient listing criteria and organ allocation criteria are commonly agreed to via National and Trans-Tasman agreements, which are published online. Current survival rates indicate approximately 94% 1-year survival with median survival in adults of approximately 20 years, whereas 75% of children are alive at 20 years. All units collaborate in research projects via the Australia and New Zealand Liver Transplant Registry and have published highly cited articles particularly on the prevention of hepatitis B virus recurrence. Outcomes for indigenous populations have also been analyzed. In conclusion, LT in Australia and New Zealand is well developed with transparent processes related to criteria for listing and organ allocation together with publication of outcomes.

    1987-04-01

    Britain and Australia have become locked in a battle of wills and wits over a nuclear legacy that is now more than 30 years old. At stake is the issue of who will pay to clean up a stretch of the central Australian outback where at least 23 kilograms of plutonium are buried in nuclear graveyards or scattered in fine particles on the ground. The plutonium was left there after a series of British nuclear weapons tests in the 1950s and 1960s. The cost of cleaning it up today, and rendering the ground safe the the Aborigines who claim it as their tribal homeland, has been estimated at up to $158 million. Australia's minister for resources, Senator Gareth Evans, went to London in October 1986 to try to involve the British in the cleanup. But Britain is still taking the stand that it had discharged any obligations on this score long ago. This question is at the heart of controversy that began mounting in the late 1970s over the British nuclear tests. It was then that Aborigines and test veterans from Britain and Australia started alleging that they had been exposed to unduly high doses of radiation. Clearly, the nuclear tests, which began as a political exercise between Britain and Australia more than 30 years ago, seem destined to remain the source of much legal, diplomatic, and financial fallout between the two countries for a long time to come.

    1991-01-21

    There is a shortage of general practitioners in rural Australia. Several recent State and federal government reports have highlighted the difficulties of rural practice. One of the reasons commonly cited for the shortage of country doctors is the lack of appropriate training in Australia's medical schools and the Family Medicine Programme. This survey of the heads of departments of community medicine/general practice of Australia's 10 medical schools and of the State directors of the Family Medicine Programme documents the present efforts to train doctors for rural general practice. A 100% response was achieved. The responses indicate much interest and effort from the Family Medicine Programme in developing rural training schemes. Though the community medicine/general practice departments demonstrate considerable interest and innovation, they are hampered by lack of resources and negative attitudes of some specialist colleagues. Overall, the main impediments are: lack of "affirmative action" admissions policies to recruit rural students; insufficient curricular time for teaching the principles of general practice; students' lack of confidence in the procedural aspects of rural practice; lack of appropriate training posts in anaesthetics; lack of appropriate general practice training posts at regional hospitals; and lack of financial resources. Some suggestions are given to improve training for rural practice in Australia. PMID:1986187

  10. Australia and the nuclear fuel cycle

    International Nuclear Information System (INIS)

    The nuclear electricity industry based on uranium fuel is now well established in 31 countries. Nuclear's ability to provide large scale base load power at costs competitive with available and politically favoured alternatives is causing it to be increasingly selected for new capacity. The World Nuclear Association data shows that current new construction together with that planned and proposed as of December 2009, will bring world nuclear electricity generating capacity from the present 373 000 MW to 876 000 MWm an increase of 112 per cent. By comparison Australia's total generating capacity (mainly from coal) is 47 000 MW, or one eighth of existing world nuclear capacity. Nuclear growth can be expected to increase further, due to continuing world-wide energy supply security issues and politically driven climate change concerns. Australia has been mining uranium for 60 eventful years, much influenced by government policy changes. Australia's un-mined resources are now the largest in the world and it is already a major supplier to the nuclear fueld cycle, in a growing market. This situation offers long term opportunities for Australia to benefit more fully and at the same time contribute to global security by further participation in the uranium-based nuclear electricity industry fuel cycle

  14. The current status of tissue banking in Australia

    International Nuclear Information System (INIS)

    Bone and Tissue Banking has been undergoing a significant metamorphosis in Australia since the publication by Simonds et al in the New England Journal of Medicine in 1992. That paper dealt with the transmission of HIV-1 from a sero negative organ and tissue donor to seven unsuspecting recipients. Forty eight recipients all received material from that donor, and only 7 of them sero converted. Those 7 received tissue which had not been processed. The remaining 41 patients received processed tissue and did not sero converted. New emerging challenges have similarly been noted in the form of Hepatitis C, HIV-2 and Creutzfeldt-Jakob disease. The Australian Orthopaedic Association has formed a National Bone and Tissue Banking Subcommittee, which in turn has produced a national guideline document. That Association aims to promote safety and efficiency in tissue banking, assist with the establishment of regional and institutional banks, maintain ongoing quality control programmes, and maintain a national register. Current testing protocol for donors and allograft segments will be explained. In addition, emphasis will be placed upon the need for a proper administrative structure within a bone and tissue blank, including the formation of a management board, listing of hierarchy and responsibility with positions, the maintenance of an up-to-date procedure manual, and a quality assurance programme. Internal safety audits are also mandatory. The paper will deal with the need for secondary sterilisation and outline both donor and recipient demographs throughout Australia. The Federal Department of Human Services and Health through its Therapeutic Goods Administration has recently published a Code of Good Manufacturing Practice. The implications of this code will be canvassed

  15. Closing the gap in nursing education:Comparing nursing registration systems in Australia and China

    2016-01-01

    Aim: To provide a better understanding of how the nursing registration process in China compares to that of Australia and to identify common features and potential barriers that may affect or facilitate the development of China's ever-demanding need for healthcare and nursing education. Background: Chinese nursing graduates are increasingly being used to augment the shortage of nurses in other countries, including Australia. However, China is desperately in need of strategies to cope with its current challenges in healthcare and nursing education. There is little discussion concerning the differences in nursing registration systems between countries, such as China and Australia. It is unknown how the differences and potential similarities of nursing registration systems in these two countries contribute to or impede nurses' training in China; or the potential for these Australia trained Chinese nursing returnees to cope with the challenges China is facing. Evaluation: Using Bereday's four steps comparison method, this paper will describe, explain, compare, and contrast the nursing registration systems of Australia and China. Key issues: Differences were found in the qualification requirements for:(1) initial registration, (2) levels of registration, (3) continuing professional development, (4) requirements of the registration renewal process, and (5) whether each country has a national nursing registration system. These factors may affect nursing education and healthcare development in China. Conclusions: Although differences in the nursing registration process between Australia and China were identified, the insights gained from this study support the development of strategies to help with China's ever-demanding need for nursing education and healthcare development, thereby alleviating its nursing shortage. Implications for nursing management: The implications of globalization of nursing education, research, and clinical practice, coupled with the nursing shortage

  16. Big News: The Indian Media and Student Attacks in Australia

    OpenAIRE

    2016-01-01

    By any measure, 2009 was a big year for news in India. And yet the safety of Indian students in Australia ranked among the major news events in India that year. The India-Australia Poll 2013 found 65 per cent of respondents believed the Indian media had accurately reported the problems faced by Indian students in Australia in 2009-10. That implies two-thirds of Indians accepted the Indian media’s mostly negative depictions of Australia. Those who believed the media reporting about Australia h...

  17. Recent developments in Australia's uranium mining industry

    International Nuclear Information System (INIS)

    Uranium is produced at two mining/milling operations in Australia - Ranger in the Alligator Rivers Region of the Northern Territory, and Olympic Dam in South Australia. In 1996, Ranger produced 4138 tonnes (t) U3O8 from stockpiled ore mined from Ranger No. 1 Orebody. The capacity of the Ranger mill is being expanded to 5000 tonnes per annum (tpa) U3O8 to coincide with the commencement of mining from No. 3 Orebody in mid-1997. The Olympic Dam copper-uranium-gold-silver deposit is the world's largest deposit of low cost uranium. The operation currently has an annual production of 85,000 t copper, 1700 t U3O8 and associated gold and silver. WMC Ltd proposes to expand annual production to 200 000 t copper and approximately 4600 t U3O8 by end of 1999. The environmental impact of the expansion is being assessed jointly by both Commonwealth and South Australian Governments. A draft Environmental Impact Statement (EIS) was released in May. Since its election in March 1996, the Liberal/National Party Coalition Government has made a number of changes to the Commonwealth Government's policies relating to uranium mining, including removal of the former Government's 'three mines' policy, and relaxation of the guidelines for foreign investment in Australian uranium mines. These changes, together with an improved outlook for the uranium market, have resulted in proposals to develop new mines at Jabiluka (Northern Territory), Kintyre (Western Australia) and Beverley (South Australia). Energy Resources of Australia Ltd proposes to develop an underground mine at Jabiluka with the ore to be processed at Ranger mill. Initial production will be 1800 tpa U3O8 which will increase to 4000 tpa U3O8 by the 14th year. The draft EIS was released for public comment in October 1996, and the final EIS is to be released in June 1997. Canning Resources Ltd proposes to mine the Kintyre deposit by open cut methods commencing in 1999 with an annual production of 1200 tpa U3O8. Heathgate Pty. Ltd

  20. Stellarator fusion neutronics research in Australia

    International Nuclear Information System (INIS)

    The new status of the H-INF Heliac Stellaralor as a National Facility and the signed international Implementing Agreement on 'Collaboration in the Development of the Stellarator Concept' represents a significant encouragement for further fusion research in Australia. In this report the future of fusion research in Australia is discussed with special attention being paid to the importance of Stellarator power plant studies and in particular stellarator fusion neutronics. The main differences between tokamak and stellarator neutronics analyses are identified, namely the neutron wall loading, geometrical modelling and total heating in in-vessel reactor components including toroidal field (TF) coils. Due to the more complicated nature of stellarator neutronics analyses, simplified approaches to fusion neutronics already developed for tokamaks are expected to be even more important and widely used for designing a Conceptual Stellarator Power Plant

  1. Introduction to Trans Australia Airlines CRM training

    Davidson, Jim

    1987-01-01

    Trans Australia believes that its excellent accident rate record is due to a number of factors. It has a good group of standard operating procedures, and its crews are pretty well self-disciplined and adhere to those procedures. But the other thing that it believes is a factor in its safety record is that perhaps it is also due to its preparedness to be innovative, to keep up with what is going on in the rest of the world and, if it looks to have value, then to be amongst the first to try it out. Trans Australia commenced a program similar to Line Oriented Flight Training (LOFT) fairly early in 1979--that being its first windshear program-- which leads to why they are doing a course of resource management training, which we have chosen to call Aircrew Team Management (ATM). This course is detailed in another presentation.

  2. Country nuclear fuel cycle profile: Australia

    International Nuclear Information System (INIS)

    Australia is a major uranium supplier to the world's nuclear power programme. It has no nuclear power plants. Uranium oxide is produced at 3 commercial mining/milling operations, Ranger, Olympic Dam and Beverley. Ranger consists of an open cut mining operation and a concentration plant. The plant has a production capability of 4660 t U/a. Olympic Dam, with a capacity of 3930 t U/a, consists of an underground mining operation and a metallurgical complex. The metallurgical complex includes a grinding/concentration circuit, a hydrometallurgical plant, a copper smelter, a copper refinery and a recovery circuit for precious metals. Beverley (based on ISL technology) has a production capability of 848 t U/a. Pilot scale research into the enrichment of uranium by the use of lasers has been conducted in Australia since the early 1990s. This research has not yet been commercialized

    2014-01-01

    We report three cases of lymphocutaneous infection caused by the thermally dimorphic fungus, Sporothrix schenckii from Australia's tropical Northern Territory. Two cases were acquired locally, making them the first to be reported from this region. All three cases presented with ulceration in the limb; however, the classical sporotrichoid spread was present only in the first two cases. Their occurrence within several weeks of each other was suggestive of a common source of environmental contamination such as hay used as garden mulch. Diagnoses were delayed in each case, with each patient having substantial exposure to ineffective antibiotics before the correct diagnosis was made. These cases bring the total number of reported sporotrichosis cases in Australia since 1951 to 199. Lessons from these cases are to consider the diagnosis of sporotrichosis in lesions of typical appearance, even in geographical settings from where this pathogen has not previously been reported.

  4. The Transmission of Chinese Medicine in Australia

    Directory of Open Access Journals (Sweden)

    Mary Garvey

    2011-09-01

    Full Text Available The paper explores some of the issues concerning the transmission of Chinese medicine in Australia, its practitioner training and the future of Chinese medicine as a distinct medical discipline in the Australian context. In China over the last century Chinese medicine was overhauled in order to align it with the biomedical perspective prevalent in the West. These changes, in turn, had important consequences for the transmission of CM in Australia and the West. But while the biomedicalisation of CM has offered the path of least resistance, it has also lead to unworkable simplifications and methodological failures. The paper thus argues for a renewed access to the tradition’s primary sources in order to ally the distinctive features and methods of traditional practice with biomedicine, as an alternative to an outright integration into biomedical practice.

    Full Text Available Abstract Background Understanding the spatial distribution of suicide can inform the planning, implementation and evaluation of suicide prevention activity. This study explored spatial clusters of suicide in Australia, and investigated likely socio-demographic determinants of these clusters. Methods National suicide and population data at a statistical local area (SLA level were obtained from the Australian Bureau of Statistics for the period of 1999 to 2003. Standardised mortality ratios (SMR were calculated at the SLA level, and Geographic Information System (GIS techniques were applied to investigate the geographical distribution of suicides and detect clusters of high risk in Australia. Results Male suicide incidence was relatively high in the northeast of Australia, and parts of the east coast, central and southeast inland, compared with the national average. Among the total male population and males aged 15 to 34, Mornington Shire had the whole or a part of primary high risk cluster for suicide, followed by the Bathurst-Melville area, one of the secondary clusters in the north coastal area of the Northern Territory. Other secondary clusters changed with the selection of cluster radius and age group. For males aged 35 to 54 years, only one cluster in the east of the country was identified. There was only one significant female suicide cluster near Melbourne while other SLAs had very few female suicide cases and were not identified as clusters. Male suicide clusters had a higher proportion of Indigenous population and lower median socio-economic index for area (SEIFA than the national average, but their shapes changed with selection of maximum cluster radii setting. Conclusion This study found high suicide risk clusters at the SLA level in Australia, which appeared to be associated with lower median socio-economic status and higher proportion of Indigenous population. Future suicide prevention programs should focus on these high risk areas.

    Directory of Open Access Journals (Sweden)

    Raina MacIntyre

    Full Text Available Increasing trends in incidence of herpes zoster (HZ have been reported in Australia and internationally. This may reflect the impact of childhood VZV vaccination programs introduced universally in Australia in late 2005. The objective of this study was to evaluate changes in incidence of HZ and PHN in Australia over time, and associated healthcare resource utilisation.Australian data on general practice (GP encounters for HZ, specific antiviral prescribing data from the pharmaceutical benefits scheme, emergency department presentations from the states of NSW and Victoria and national hospitalisation data for HZ were analysed for time trends using regression models. Two time periods (2000-2006 and 2006-2013 were compared which correspond broadly with the pre- and post- universal VZV vaccination period.All data sources showed increasing rates of HZ with age and over time. The GP database showed a significant annual increase in encounters for HZ of 2.5 per 100,000 between 1998 and 2013, and the rates of prescriptions for HZ increased by 4.2% per year between 2002 and 2012. In the 60+ population HZ incidence was estimated to increase from 11.9 to 15.4 per 1,000 persons using GP data or from 12.8 to 14.2 per 1,000 persons using prescription data (p<0.05, between the two periods. Hospitalisation data did not show the same increasing trend over time, except for the age group ≥80 years. Most emergency visits for HZ were not admitted, and showed significant increases over time.The burden of HZ in Australia is substantial, and continues to increase over time. This increase is seen both pre- and post-universal VZV vaccination in 2005, and is most prominent in the older population. The substantial burden of HZ, along with ageing of the Australian population and the importance of healthy ageing, warrants consideration of HZ vaccination for the elderly.

  14. The regulation of herbal medicines in Australia

    International Nuclear Information System (INIS)

    Complementary medicines, including herbal medicines in Australia are regulated under therapeutics goods legislation. Based on risk, Australia has developed a two tiered approach to the regulation of therapeutic goods. Listed medicines are considered to be of lower risk than Registered medicines. Most, but not all, complementary medicines are Listed medicines. Managing the risk associated with therapeutic goods, including complementary medicines, is exerted through the processes of licensing of manufacturers; pre-market assessment of products; and post-market regulatory activity. Herbal medicines may be associated with low or high risk depending on the toxicity of ingredients, proposed dosage, appropriateness of the indications and claims for self-diagnosis and management and the potential for adverse reactions. Registered medicines are individually evaluated for safety, quality and efficacy before they are released onto the market. Listed medicines are individually assessed by the Therapeutic Goods Administration for compliance with legislation, they are not evaluated before release. They may only be formulated from ingredients that have undergone pre-market evaluation for safety and quality and are considered low risk. Listed complementary medicines may only carry indications and claims for the symptomatic relief of non-serious conditions, health maintenance, health enhancement and risk reduction. An important feature of risk management in Australia is that early market access for low risk complementary medicines is supported by appropriate post-market regulatory activity

  15. Developments in Australia : native title and reconciliation

    Energy Technology Data Exchange (ETDEWEB)

    Chaney, F. [National Native Title Tribunal, Perth, WA (Australia)

    2004-07-01

    Until 1992, there was no recognition in the Australian legal system of property or other laws recognizing Indigenous rights concerning European colonial settlement and beyond. Native title was first recognized in 1992. This paper presented an outline of the history leading up to the creation of the National Native Title Tribunal in Perth, Australia, an organization whose aims are to create recognition of native title in Australia. The objects of the Native Title Act of 1993 were discussed, as well as attempts to reconcile indigenous and non-indigenous interests. Particular attention was drawn to the mining industry, as a practical example of the paradigm change in relation to indigenous rights, with an outline of the mining industry's values underlying principles concerning indigenous relations. It was concluded that while there are stringent limits on what is available through the native title process, mediation procedures mean that opportunities for agreement exist. Although reconciliation is in its infancy in Australia, there is a growing acceptance that Aboriginal rights must be considered. The agreement making which is encouraged by the native title process is an acknowledgment of a new relationship in which indigenous people are stakeholders. 72 refs., 5 figs.

Although only a small number of extensive monitoring programs on acid deposition have been carried out in Australia, the evidence to date indicates that acid rain is not a national problem. A number of regions however may warrant careful investigation. In particular, the Kalgoorlie region in Western Australia and Mt. Isa in Queensland which by 1990 will have a combined sulfur dioxide emission of 1300 kilotonnes/annum - approximately 85% of the total anthropogenic Australian emission value for 1985. In view of the quality of existing data on rain acidity in the Latrobe Valley, the projected increase in sulfur dioxide emission from coal-fired power stations by the year 2005, and the acid susceptibility of alpine humus soils in national parks to the north and south of the Valley, new studies are recommended for this region. Other regions that are susceptible to soil acidification include the eastern parts of the Dividing Range in north Queensland and sections of the Kakadu National Park in the Northern Territory. 55 refs., 1 tab, 3 figs

  17. Australia explores apprehensively the renewable energies

    International Nuclear Information System (INIS)

    The development of new energy technologies worldwide is a result of the depletion of fossil fuel and non-renewable resources and of the collective awareness about the potential consequences of the greenhouse effect. The strong dependence of Australia with respect to fossil fuels is a consequence of its abundant resources (mainly coal) but leads to important CO2 emissions. Australia is thus the first emitter of greenhouse gases per habitant in the world and its contribution to global emissions is of 1.6% for only 0.3% of the world population. Fortunately, despite fossil fuel reserves amply sufficient with respect to the needs, the production of clean energy is developing in Australia and research programs have been implemented for the exploration of new energy generation technologies: wind turbines for weak winds, hybrid wind-diesel power systems, oscillating wave column (OWC) power generation systems, bio-energetic cultivation techniques (combined production of eucalyptus oil, of activated charcoal, and of electricity with soil desalination), photovoltaic power generation, EnviroMission project of giant solar tower, research on hydrogen production techniques (solar thermal conversion of natural gas, water electrolysis with photo-electrodes), fuel cells for domestic cogeneration, hot dry rock geothermal systems.

  18. Nuclear regulation in Australia - future possibilities

    International Nuclear Information System (INIS)

    Australia's current nuclear regulatory arrangements reflect two major factors: that we are a federation, with a constitutional division of powers between the Commonwealth and the States, and that we have no nuclear industry, other than uranium mining. Australia's only nuclear facilities are operated by a Commonwealth instrumentality, ANSTO. Current Commonwealth regulatory arrangements are a response to international treaty commitments -principally the NPT (Treaty on the Non-Proliferation of Nuclear Weapons) -and to the commencement of commercial uranium mining and export in the late 1970's. Although at present no nuclear industry activities, other than mining, are in prospect, this might not always be the case, and with the establishment of ARPANSA (the Australian Radiation Protection and Nuclear Safety Agency) it is timely to give some thought to regulatory arrangements which might be appropriate to Australia's future circumstances. This paper will discuss the regulation activities relating to the nuclear fuel cycle , i e activities involved with the production and use of nuclear materials (uranium, thorium and plutonium) for the generation of energy through nuclear fission

  19. Climate change in Australia: technical report 2007

    International Nuclear Information System (INIS)

    The purpose of this report is to provide an up-to-date assessment of observed climate change over Australia, the likely causes, and projections of future changes to Australia's climate. It also provides information on how to apply the projections in impact studies and in risk assessments. The two main strategies for managing climate risk are mitigation (net reductions in greenhouse gas emissions) to slow climate change and adaptation to climate impacts that are unavoidable. A number of major advances have been made since the last report on climate change projections in Australia (CSIRO 2001) including: a much larger number of climate and ocean variables are projected (21 and 6 respectively); a much larger number (23) of climate models are used; the provision of probabilistic information on some of the projections, including the probability of exceeding the 10th, 50th and 90th percentiles; greater emphasis on projections from models that are better able to simulate observed Australian climate; a detailed assessment of observed changes in Australian climate and likely causes; and information on risk assessment, to provide guidance for using climate projections in impact studies

  20. Media and Australia's replacement reactor project

    International Nuclear Information System (INIS)

    In September 1997, the Commonwealth Government of Australia announced a proposal to build a replacement nuclear research reactor at Lucas Heights in Sydney. Extensive public consultation, parliamentary debate and independent reports were prepared to ensure that the new facility would meet strict international requirements, national safety and environmental standards, and performance specifications servicing the needs of Australia - for decades to come. On 6 June 2000, Argentine company INVAP SE was announced as the preferred tenderer. In July 2000 contracts were signed between INVAP and the Australian Nuclear Science and Technology Organisation for the construction the replacement reactor, due to be completed in 2005. In order to retain a strong local presence, INVAP undertook a joint venture with two of Australia's foremost heavy construction businesses. Briefly the new research reactor will be a replacement for the ageing Australian Reactor (HIFAR). Nuclear science and technology, in Australia, is no stranger to media controversy and misinformation. Understandably the announcement of a preferred tenderer followed by the signing of contracts, attracted significant national and international media attention. However in the minds of the media, the issue is far from resolved and is now a constant 'news story' in the Australian media. Baseless media stories have made claims that the project will cost double the original estimates; question the credibility of the contractors; and raise issues of international security. The project is currently linked with Australia's requirements for long term nuclear waste management and there has been an attempt to bring national Indigenous People's issues into play. Some of these issues have been profiled in the press internationally. So, just to set the record straight and give you an appropriate impression of what's 'really happening' I would like to highlight a few issues, how ANSTO dealt with these, and what was finally reported

  1. Risk of Buruli ulcer and detection of Mycobacterium ulcerans in mosquitoes in southeastern Australia.

    2011-09-01

    Full Text Available BACKGROUND: Buruli ulcer (BU is a destructive skin condition caused by infection with the environmental bacterium, Mycobacterium ulcerans. The mode of transmission of M. ulcerans is not completely understood, but several studies have explored the role of biting insects. In this study, we tested for an association between the detection of M. ulcerans in mosquitoes and the risk of BU disease in humans in an endemic area of southeastern Australia. METHODOLOGY/PRINCIPAL FINDINGS: Adult mosquitoes were trapped in seven towns on the Bellarine Peninsula in Victoria, Australia, from December 2004 to December 2009 and screened for M. ulcerans by real-time PCR. The number of laboratory-confirmed cases of BU in permanent residents of these towns diagnosed during the same period was tallied to determine the average cumulative incidence of BU in each location. Pearson's correlation coefficient (r was calculated for the proportion of M. ulcerans-positive mosquitoes per town correlated with the incidence of BU per town. We found a strong dose-response relationship between the detection of M. ulcerans in mosquitoes and the risk of human disease (r, 0.99; 95% CI, 0.92-0.99; p < 0.001. CONCLUSIONS/SIGNIFICANCE: The results of this study strengthen the hypothesis that mosquitoes are involved in the transmission of M. ulcerans in southeastern Australia. This has implications for the development of intervention strategies to control and prevent BU.

    The Varroa mite (Varroa destructor) is implicated as a major disease factor in honey bee (Apis mellifera) populations worldwide. Honey bees are extensively relied upon for pollination services, and in countries such as New Zealand and Australia where honey bees have been introduced specifically for commercial pollinator services, the economic effects of any decline in honey bee numbers are predicted to be profound. V. destructor established in New Zealand in 2000 but as yet, Australia remains Varroa-free. Here we analyze the history of V. destructor invasion and spread in New Zealand and discuss the likely long-term impacts. When the mite was discovered in New Zealand, it was considered too well established for eradication to be feasible. Despite control efforts, V. destructor has since spread throughout the country. Today, assessing the impacts of the arrival of V. destructor in this country is compromised by a paucity of data on pollinator communities as they existed prior to invasion. Australia's Varroa-free status provides a rare and likely brief window of opportunity for the global bee research community to gain understanding of honey bee-native pollinator community dynamics prior to Varroa invasion.

  3. The state of legislation and policy regarding nuclear issues in Australia and South Australia

    International Nuclear Information System (INIS)

    In the author's opinion, nuclear issues are largely neglected, and dealt with inadequately, in Australian legislation. This can be partly understood when Australia's international position is investigated and considered, but it is a long way from being justifiable, particularly in the context of public opinion. Current legislation covers safety and environmental impact assessment of nuclear developments, but does not provide appropriate critical assessment processes. Yet in the new Environment Protection and Biodiversity Conservation Act 1999, 'nuclear activities' are considered to be not only a matter of environmental significance, but a matter of national environmental significance. Given that environmental issues are generally those which impact upon human health, quality of life and ecosystems, it would seem that nuclear issues are clearly and definitely environmental issues, despite their curious absence from much 'environmental' literature. This article reviews the current state of legislation in Australia, with particular concentration on the author's home State of South Australia

    2011-01-01

    The social and legal acceptability of third-party reproduction varies around the world. In Australia, gamete and embryo donation and surrogacy are permitted within the regulatory framework set out by federal and state governments. The aim of this paper is to describe the social context and regulatory framework for third-party reproduction in Australia. This is a review of current laws and regulations related to third-party reproduction in Australia. Although subtle between-state differences exist, third-party reproduction is by and large a socially acceptable and legally permissible way to form a family throughout Australia. The overarching principles that govern the practice of third-party reproduction are altruism; the right of donorconceived people to be informed of their biological origins; and the provision of comprehensive counselling about the social, psychological, physical, ethical, financial and legal implications of third-party reproduction to those considering donating or receiving gametes or embryos and entering surrogacy arrangements. These principles ensure that donors are not motivated by financial gain, donor offspring can identify and meet with the person or persons who donated gametes or embryos, and prospective donors and recipients are aware of and have carefully considered the potential consequences of third-party reproduction. Australian state laws and federal guidelines prohibit commercial and anonymous third-party reproduction; mandate counselling of all parties involved in gamete and embryo donation and surrogacy arrangements; and require clinics to keep records with identifying and non- identifying information about the donor/s to allow donor-conceived offspring to trace their biological origins.

    2008-01-01

    The wetlands in Australia are of great physical, chemical and biological variety due to the continent's age, geological history and climate. The traditional physical and biological threats remain as the main challenges for wetland preservation in Australia. However, it has been increasingly recognized that the immediate survival of wetlands are being affected by more subtle threats, such as administrative and political threats. This paper identifies these non-physical threats and discusses how and why they have become the major barriers for sustainable wetland preservation in Australia. Finally, this paper calls for more practical policies and solutions to be implemented for sustainable wetland preservation in Australia.

  12. Paediatric CT imaging trends in Australia

    International Nuclear Information System (INIS)

    Full text: The use of CT has rapidly increased since its introduction. Although an important medical tool for diagnosis and treatment, CT is rec ognised as being among the highest contributors to population radiation exposure. As the risks associated with exposure are higher for children than for adults, this study assessed the impact of paediatric CT in Australia by analysing imaging trends. CT imaging trends were derived from Medicare data. Comparable data from a dedicated paediatric hospital (Royal Children's Hospital Melbourne (RCH)) were analysed to determine the validity of utilising Medicare statistics in the younger age groups. The resulting trends reflect the situation for paediatric CT imaging in Australia. In 2009, 2.1 million CT services were billed to Medicare in Australia for children and adults. The average annual growth in the number of CT services provided since 1994 was 8.5%, compared with population growth of 1.4%. Comparison of RCH and Medicare data revealed that only one third of pae diatric CT imaging is captured by Medicare. Combining the data sets showed that over the last 20 years, there has been an average annual increase of 5.1% in the CT imaging rate for 0 to 18-year-olds. However, in recent years, growth in the imaging rate for 11 to 18-year-olds has slowed, while for 5 to 10-year-olds the imaging rate has declined. The significant growth in CT services is attributable to increased demand from the adult demographic. Conversely, increases in the imaging rate for paediatric patients have slowed overall. In fact, for some age groups the rate has fallen.

  13. Development of NORM Management in Australia

    International Nuclear Information System (INIS)

    Australia has had a long involvement with NORM, mainly because of mining and processing of mineral ores. Radium mining was carried out in the early 20th century. After 1949, there was a rapid expansion in uranium mining (particularly in the Northern Territory) and mineral sand mining. Australia is a Federation of the Commonwealth, six States and two Territories, which independently regulate within their jurisdiction. Early mineral extraction and processing operations were unregulated, resulting in the existence of a large number of legacy sites. Regulation of uranium mining started in the 1970s, and mineral sand mining after 1980. The regulations vary in detail between jurisdictions. Most other NORM situations are not regulated in any of the States or Territories. A major review of the Western Australian mineral sand industry in the 1980s led to considerable reductions in doses to workers. Remediation of many of the old uranium mine sites in the Northern Territory has been carried out over the last 15 years and is continuing. International awareness of NORM as a potential source of risk to workers, members of the public and the environment has increased significantly in recent years. After an extensive stakeholder consultation process and the development of a position paper summarizing the NORM situation in Australia, a Safety Guide was developed, to enhance awareness and provide general guidance on NORM management. The Safety Guide recommends a graded approach to NORM management, based on exclusion, exemption, clearance and regulation. It includes sections on general radiation protection principles, impact assessment, assessment of the need for regulation, development of a NORM management plan, and annexes on NORM management in the oil and gas, bauxite processing and phosphate industries, written by experts from the industries. These industries were chosen because of their experience with NORM management and the availability of good data. (author)

    Full Text Available This study explores how monetary policy changes flow through the banking sector in Australia. Drawing on data between 2004 and 2010, we divide banks into three groups according to their size, and examine the impact of that cash rate change on lending of different types of loans. We find the response of bank lending after a monetary policy change varies with the size of the bank as well as the types of loan. Smaller banks are more sensitive to policy rate changes, and household loans, government loans and intra-group loans are less responsive to monetary policy compared with financial and non-financial loans.

    Paleoclimate research indicates that the Australian instrumental climate record (˜ 100 years) does not cover the full range of hydroclimatic variability that is possible. To better understand the implications of this on catchment-scale water resources management, a 1013-year (1000-2012 common era (CE)) annual rainfall reconstruction was produced for the Williams River catchment in coastal eastern Australia. No high-resolution paleoclimate proxies are located in the region and so a teleconnection between summer sea salt deposition recorded in ice cores from East Antarctica and rainfall variability in eastern Australia was exploited to reconstruct the catchment-scale rainfall record. The reconstruction shows that significantly longer and more frequent wet and dry periods were experienced in the preinstrumental compared to the instrumental period. This suggests that existing drought and flood risk assessments underestimate the true risks due to the reliance on data and statistics obtained from only the instrumental record. This raises questions about the robustness of existing water security and flood protection measures and has serious implications for water resources management, infrastructure design and catchment planning. The method used in this proof of concept study is transferable and enables similar insights into the true risk of flood/drought to be gained for other paleoclimate proxy poor regions for which suitable remote teleconnected proxies exist. This will lead to improved understanding and ability to deal with the impacts of multi-decadal to centennial hydroclimatic variability.

    Full Text Available The annually increasing firm exits have significant financial, legal and social impacts on productivity, employment and economic growth in Australia. However, evidence of the impacts of firm exits is sparse. This paper undertakes a first-ever study that empirically investigates the determinants and their impacts on firm churn. This paper is innovative to the literature in four aspects: (1 Local Region Areas (LGAs data, rarely available in other countries, has been used for the analysis; (2 using LGAs as the basic analytical unit is able to eliminate the heterogeneity problems encountered by other studies which are based on national and cross-national data; (3 panel data modelling techniques identify robust evidence; (4 systematic statistical tests guarantees the robustness of the results. The dataset, provided by Australia Bureau of Statistics, include 3462 observations of 577 Local Government Areas (LGAs during 2004-2009. The research identifies variables positively and negatively affecting the exits and finds that size matters in determining business exits. The last section concludes with a discussion of limitations and future research directions.

  3. Sustainability in Australia, past, present and future

    International Nuclear Information System (INIS)

    Over the last 50 years Australia has generally maintained adequate energy supplies to its population in an increasingly efficient and sustainable manner It has also been able to help sustain other economies in supplying energy resources of coal, gas and uranium. This provides 20% of Australia's export income, contributing to the quality of life experienced by Australians.Presently the reserve margin in the electricity power system is adequate and, with the exception of oil, ample local energy resources are available. Over the same period the doubling in energy generation efficiency has matched the population growth in NSW The same contributions by technology and population can be expected over the next 50 years. The growth in demand has however increased by a factor of about five.Sensible demand management could reduce this to a more acceptable figure over the next 50 years as shown in two possible scenarios. This, coupled with ongoing energy exports will help sustain the quality of life in this economy

  4. Australia's South African war 1899-19021

    Directory of Open Access Journals (Sweden)

    2012-02-01

    Full Text Available Around twenty thousand Australians fought in the great war between the British empire and the republics of the Orange Free State and the Transvaal. Those Australians constituted five in every thousand of their people, or three in every two hundred of their male workers. In South Africa they made up just one in every twenty-five soldiers in a British army of almost half a million.2 As these bald figures immediately suggest, Australia's contribution to the war was too small to be decisive, and its experience of the war involved too few of its people to make a powerful impact on its society, let alone wrench its history onto some different course. Still, that contribution and that experience were unprecedented for a people who had never before gone to war as a people, and deserve more attention - and more balanced, dispassionate, critical attention - than they've yet received from historians of the war, of Australia, and of the British empire.3 In this lecture I'll strive for such balance by outlining why and how Australians went to war in South Africa, what their soldiers did there, and the war's legacy for their country and their descendants today.

  5. Developments in uranium solution mining in Australia

    International Nuclear Information System (INIS)

    The last five years have seen rapid developments in uranium solution mining in Australia, with one deposit brought into production (Beverley, 1,000 tpa U3O8) and another close to receiving development approval (Honeymoon, 500 expanding to 1,000 tpa U3O8 proposed). The deposits were discovered during extensive exploration of the Frome Basin in South Australia in the early 1970s and were mothballed from 1983 to 1996 due to Government policies. Uranium mineralisation at Beverley, Honeymoon and other related prospects is hosted in unconsolidated coarse grained quartz sands which are sealed in buried palaeovalleys. Both projects have successfully trialled acid leaching methods and have confirmed high permeability and confinement of the target sands. At Beverley an ion exchange process has been adopted, whereas at Honeymoon solvent extraction has been trialled and is proposed for future production Australian production economics compare favourably with US counterparts and are likely to be within the lower quartile of world costs

  6. Private health insurance and regional Australia.

    2005-03-21

    Since 1996, an increasing proportion of federal government expenditure has been directed into Australia's healthcare system via private health insurance (PHI) subsidies, in preference to Medicare and the direct funding of public health services. A central rationale for this policy shift is to increase the use of private hospital services and thereby reduce pressure on public inpatient facilities. However, the impact of this reform process on regional Australia has not been addressed. An analysis of previously unpublished Australian Bureau of Statistics data shows that regional Australians have substantially lower levels of private health fund membership. As a result, regional areas appear to be receiving substantially less federal government health funding, compared with cities, than if these funds were allocated on a per-capita basis. We postulate that the lower level of membership in regional areas is mainly due to the limited availability of private inpatient facilities, making PHI less attractive to rural Australians. We conclude that PHI as a vehicle for mainstream federal health financing has potential structural failures that disadvantage regional Australians. PMID:15777145

    Donors are the key to the core business of Blood Collection Agencies (BCAs). However, historically, they have not been a focus of research undertaken by these organizations. This model is now changing, with significant donor research groups established in a number of countries, including Australia. Donor research in the Australian Red Cross Blood Service (Blood Service) is concentrated in the Donor and Community Research (DCR) team. Cognizant of the complex and ever-changing landscape with regard to optimal donor management, the DCR team collaborates with academics located at universities around Australia to coordinate a broad program of research that addresses both short- and-long term challenges to the blood supply. This type of collaboration is not, however, without challenges. Two major collaborative programs of the Blood Service's research, focusing on i) the recruitment and retention of plasmapheresis donors and ii) the role of the emotion pride in donor motivation and return, are showcased to elucidate how the challenges of conducting collaborative BCA research can be met. In so doing, these and the other research programs described herein demonstrate how the Blood Service supports and contributes to research that not only revises operational procedures but also contributes to advances in basic science.

Risk assessment and control procedures including the health surveillance of workers, other special occupational groups and members of the general public are outlined. (author)

  9. Big News: The Indian Media and Student Attacks in Australia

    Full Text Available By any measure, 2009 was a big year for news in India. And yet the safety of Indian students in Australia ranked among the major news events in India that year. The India-Australia Poll 2013 found 65 per cent of respondents believed the Indian media had accurately reported the problems faced by Indian students in Australia in 2009-10. That implies two-thirds of Indians accepted the Indian media’s mostly negative depictions of Australia. Those who believed the media reporting about Australia had been accurate were more likely to be from large cities, be tertiary educated and have relatively high-incomes. The poll found 62 per cent of respondents thought Australia was a dangerous place for Indian students and that 61 per cent believed attacks on Indian students were motivated by racism. The results suggest negative perceptions about Australia created by the media’s portrayal of the student attacks linger in the Indian community. The timing of the initial attacks, and the imagery associated with them, helped attract and sustain media attention on the issue. The diplomatic tensions created by the crisis highlighted the growing influence of the broadcast media on India’s foreign relations. But the episode also exposed a deep lack of understanding about India in Australia. Governments were slow to comprehend how much damage media coverage of student attacks could do to Australia’s reputation in India.

    Australia's and Canada's real wage experiences between 1870 and 1913 were distinctive. Faster productivity growth underpinned Canada's overtaking of Australia's wage levels. The globalization forces of migration and trade also shaped their comparative wages, principally by reducing wage growth in...... Canada. Immigration increased slightly Australia's real wages, but reduced wage levels in Canada, and tempered there the beneficial effects of rising productivity and improving terms of trade. In contrast, wage earners' share of national income rose after 1890 in Australia, with the productivity slowdown...... hitting chiefly rents and profits. Distributional shifts favouring wage earners in Australia, and the depressing effects of mass immigration on wages in Canada, limited Canada's wage lead before 1914, despite her faster productivity growth...

  20. Political and economic structure and energy industry status of Australia

    Energy Technology Data Exchange (ETDEWEB)

    Bang, K.Y. [Korea Energy Economics Institute, Euiwang (Korea, Republic of)

    1998-06-01

    Looking at the composition of energy resources import of Korea per each country, Australian-made import takes up 11.8% of total energy resources import. It possesses the highest import composition of 30.5% when petroleum sector is excluded. In the order of Korea`s mineral import per each country, Australia still keep the number one position every year though Korea keep promoting the diversification of import sources. In the mean time, reflecting on the treatment aspect of import country of Australia, when Korea`s energy, the import size of resources, import intensity of Australia`s primary raw material resources and international resources situation are considered, Korea is thought to receive less treatment from Australia as the second export country of Australia than Japan who is the number one export country of Australia, relatively. Though the increase ratio of Korean tourists in Australia is the highest for the past few years and international promotion effect shows big with the IMF financial support of Korea who faces sudden economic crisis recently as a momentum, sincere evaluation through in-depth analysis between Korea and Australia is still in the initial stage. The necessity to diagnosis the general political and economic structure of Australia more in detail emerges as trade volume between two countries keep growing, esp. in the import of energy and resources sectors, the number of visits between two countries keep increasing. Therefore, the purpose of this study lies mainly in the structure of the new Australian government, general macroeconomics structure and the understanding of energy industry-related status such as energy supply and demand, development status of energy, related laws, and government`s energy agencies, etc. 6 refs., 3 figs., 22 tabs.

  1. Area-wide management of fruit flies in Australia

    International Nuclear Information System (INIS)

    Full text: The Commonwealth of Australia is comprised of six States and several Territories. Each State and Territory Government maintains quarantine activities for its borders under the guidance of the Commonwealth Government. These activities, with regard to fruit flies, include quarantine at airports and harbours, compliance with import and export regulations and monitoring for, and action against, incursions of exotic fruit fly pests. There are about eighty species of fruit fly that are native to Australia that infest mainly native fruit and vegetables but, of these, six are classed as pests of horticultural significance. The Queensland fruit fly (Bactrocera tryoni) is by far the most destructive of these native Australian fruit fly species. Another, non-native species, now endemic to parts of Western Australia, which arrived in Australia in the 1890's, the Mediterranean fruit fly (Ceratitis capitata), is just as damaging and it, too, is a critical quarantine pest. The distribution of these flies in Australia is such that not all pest species inhabit the same region. Quarantine restrictions are placed by States and fruit fly free-areas within States due to pest fruit fly species that are not native there. For example the State of Tasmania, to the southeast of Australia, is classified as entirely free from pest fruit flies. Fruit fly host produce exported to Tasmania from the rest of Australia is either prohibited or allowed entry following various quarantine requirements such as an approved postharvest disinfestation treatment. The State of Western Australia is free from Queensland fruit fly, but the eastern States of New South Wales and Queensland are not. while the eastern states are free from Mediterranean fruit fly and Western Australia is not. Quarantine restrictions are in place on trade between eastern and western Australia. Mediterranean fruit fly is now endemic to parts of Western Australia and nowhere else in Australia. It is a most destructive pest

  2. World nuclear energy in relation to Australia's uranium

    International Nuclear Information System (INIS)

    In the last 40 years nuclear energy has taken Its place as a major source of electricity worldwide. It now produces 17 per cent of the world's electricity and could conceivably produce a higher proportion, to displace some six billion tonnes of carbon dioxide emissions per year. Concerns about global warming and environmental quality now underline the virtues of nuclear electricity among alternative sources of energy. Global electricity demand is rapidly increasing as a proportion of total energy usage. The proportion has doubled since 1960 and the demand is expected to increase at least 75 per cent between now and 2020. The source of this extra capacity, and the replacement of present capacity, raise questions with major resource and environmental implications. Today nuclear energy is a mature technology. Over 1200 nuclear reactors have been built and operated, some of these have been decommissioned, and among the 440 reactors in commercial operation the first advanced reactors are now entering service. Some 8000 reactor-years of operation have, with the sole exception of Chernobyl, shown nuclear energy to be extremely safe and reliable. High-level wastes are being managed properly and in different parts of the world two strategies are applied to this. Australia has a major role as a long-term supplier of uranium, since it holds almost 30 per cent of the world's reserves. This, along with an impending sellers' market for uranium, is making it an opportune time to develop new mines here. However, after several decades of concern about civil nuclear energy contributing to the arms race, we now have uranium liberated from nuclear weapons stockpiles being diluted for use in civil reactors, which will supplement ex-mine supply. The public acceptability of nuclear energy remains the critical factor in its future and hence in ours

  3. Diversity and abundance of photosynthetic sponges in temperate Western Australia

    2009-02-01

    Full Text Available Abstract Background Photosynthetic sponges are important components of reef ecosystems around the world, but are poorly understood. It is often assumed that temperate regions have low diversity and abundance of photosynthetic sponges, but to date no studies have investigated this question. The aim of this study was to compare the percentages of photosynthetic sponges in temperate Western Australia (WA with previously published data on tropical regions, and to determine the abundance and diversity of these associations in a range of temperate environments. Results We sampled sponges on 5 m belt transects to determine the percentage of photosynthetic sponges and identified at least one representative of each group of symbionts using 16S rDNA sequencing together with microscopy techniques. Our results demonstrate that photosynthetic sponges are abundant in temperate WA, with an average of 63% of sponge individuals hosting high levels of photosynthetic symbionts and 11% with low to medium levels. These percentages of photosynthetic sponges are comparable to those found on tropical reefs and may have important implications for ecosystem function on temperate reefs in other areas of the world. A diverse range of symbionts sometimes occurred within a small geographic area, including the three "big" cyanobacterial clades, Oscillatoria spongeliae, "Candidatus Synechococcus spongiarum" and Synechocystis species, and it appears that these clades all occur in a wide range of sponges. Additionally, spongin-permeating red algae occurred in at least 7 sponge species. This study provides the first investigation of the molecular phylogeny of rhodophyte symbionts in sponges. Conclusion Photosynthetic sponges are abundant and diverse in temperate WA, with comparable percentages of photosynthetic to non-photosynthetic sponges to tropical zones. It appears that there are three common generalist clades of cyanobacterial symbionts of sponges which occur in a wide

  4. Australia's changing natural gas and pipeline industry

    International Nuclear Information System (INIS)

    The future is bright for continued development of Australia's natural gas pipeline infrastructure, as well as for privatization and private energy infrastructure growth. Gas demands are growing and the development of open access principles for all natural gas transmission and distribution pipelines heralds a much more market focused industry. Within the next few years gas-on-gas competition will apply to supply, pipelines, and retail marketing. No longer will operators be able to pass on high costs resulting from inefficiencies to their customers. This article describes the changing Australian gas industry, evaluates the drivers for change and looks at ways the industry is responding to new regulatory regimes and the development and use of new pipeline technology

  5. Clocks for quaternary environments in Australia

    International Nuclear Information System (INIS)

    The Australian continent offers a variety of natural systems where records of the Earth's past environment have been stored, including sediment cores, tree rings, rock surfaces and corals. Rock varnish, mud-wasp nests and pack-rat middens provide alternative archives for vegetation and environmental change in arid areas, where continuous sedimentary sequences or trees are not available. Each of these media contain specific information on past climatic conditions but we must determine their chronology and decipher the relevant environmental parameters. Cosmogenic radionuclides, such as 14C, 10Be, 26Al and 36Cl, analysed by accelerator mass spectrometry, provide valuable radiometric clocks to establish an absolute time scale for the environmental events of the Quaternary. U-series, potassium-argon, argonargon and optically stimulated luminescence are other dating methods used in palaeoenvironmental studies. ANSTO supports the Quaternary science community in Australia providing the analysis of long-lived radionuclides: some significant projects from this program will be illustrated. (author)

  6. Australia's uranium: worth a fresh look?

    International Nuclear Information System (INIS)

    Australia's uranium production in l988 is less than 4 300 tonnes U annually - about 11% of World outside Communist areas (Woca) production, yet the country apparently possesses the largest uranium resources in the world. The political background, influenced by environmental and social considerations and a strong anti-uranium lobby, is perceived as the chief factor in limiting commercial exploitation of these resources. Prospects for a future expansion of production commensurate with the scale of the resources, depend on whether a new uranium policy will emerge. Such a policy would have to put the issues of development priority and production capacity in the hands of the market, reserving for the government the proper issues of safeguards and general trade policy. All this, however, would be subject to the reaction of the world market. (author)

  7. Radioiodine in kelp from western Australia

    Energy Technology Data Exchange (ETDEWEB)

    Marsh, K.V.; Buddemeier, R.W.; Wood, W.; Smith, C.

    1987-03-25

    As part of a program to survey low levels of radioactivity in the marine environment of the southern hemisphere, we have studied the distribution and uptake of /sup 131/I found in the subtidal kelp Ecklonia radiata, on the west coast of Australia. Concentrations of 5 to 75 fCi/g of /sup 131/I exist in this species over a considerable distance along the coast. We have characterized the principal source of the /sup 131/I and found a general temporal correlation between the amount of radioiodine discharged from sewer outfalls and its concentration in kelp. Transplant experiments have enabled us to estimate uptake and depuration rates, and our results are consistent with laboratory measurements made by others.

  8. Issues in nano technologies for Australia

    International Nuclear Information System (INIS)

    The Australian Government in late 2005 created a National Nano technology Taskforce that produced a paper, 'Options for a National Nano technology Strategy', in November last year. As an input to the National Nano technology Strategy Taskforce, in early 2006 the National Academies Forum was contracted by the Department of Industry, Tourism and Resources to produce a report Environmental, Social, Legal and Ethical Aspects of the Development of Nano technologies in Australia (which is available at www.naf.org.au/symposia). The report drew on the expertise of Fellows from the four academies in workshops in Melbourne and Sydney and from discussions with other experts, and expressed its outcomes as a set of opinions to assist in developing guidelines for a National Nano technology Strategy

  9. Goodwyn project under way off NW Australia

    International Nuclear Information System (INIS)

    This paper reports that the $2 billion (Australian) Goodwyn field development project on Australia's Northwest Shelf is under way with installation of a 17,500 metric ton steel platform jacket. Northwest Shelf project operator Woodside Petroleum Pty. Ltd. and partners are continuing with an extensive exploration program in the Northwest Shelf area. The group expects to begin soon a wide ranging 3-D seismic survey over the WA-28-P license area and the Northwest Shelf production permits. The goal is to identify new and appraise existing oil and gas prospects in the region for an exploratory drilling campaign to begin in first half 1993. Finding more gas reserves would bode well for extending existing LNG contracts with Japan or competing for new markets in Japan, South Korea, and Taiwan

    The Australian national satellite system, Aussat, will commence operations in 1985 after launch of the two initial Aussat communications satellites. Australia is a member of Intelsat, which currently provides both international telephone links and television services to 50 Outback communities. The project was organized in study areas of satellite design and plans for the ground segment, major city earth stations, and minor earth stations. Aussat services will include low power DBS of radio and television, telephony, voice and data communications for minerals exploration and medical care, a school of the air, ATC links, emergency and disaster relief communications, data transfer, and voice conferencing.Initial configurations include Ku-band satellites launched by the Shuttle, with telemetry in the 12/14 GHz bands. The Aussat organization will be eventually transformed to 49 percent private ownership.

  12. Neutron-rich radioisotope production in Australia

    International Nuclear Information System (INIS)

    The author discusses Australia's Replacement Research Reactor (RRR) and the applications of the range of radioisotopes it will produce. The ANSTO's RRR will produce radioisotopes that have medical., industrial and environmental applications. Medicinal radioisotopes would provide the nuclear medicine physicians and oncologists with the necessary tool to non-invasively diagnose and cure diseases, ranging from cancer to infections. Industrial radioisotopes provide the industrial community with high technology tools to evaluate and assess the status of high reliability equipment with respect to safety and functionality in a non-destructive modality. The current commercial radioisotope sources include 60Co, 169Yb and 192Ir with source strengths limited by the HlFAR neutron flux and capacity. These sources are primarily used for industrial X ray moisture, level and thickness gauging. The RRR will allow expansion of the commercial source strengths and allow ANSTO to meet the growing commercial Australasian market for radioactive sources

  13. Public policy in a multicultural Australia.

    Science.gov (United States)

    Zubrzycki, J

    1987-03-01

    The debate on the consequences of large-scale immigration in the making of public policy began in 1968. Muliculturalism is for all Australians and any social policy designed for the benefit of one group in the population must have profound consequences on all people. 40% of the Australian population was born overseas or have at least 1 parent born overseas. Almost 1/4 of the population has ethnic roots in other than the Anglo-Celtic majority. The ideal of moral progress, greater equality, and improvement is the motive force in society. The presence of social heterogeneity--religious or ethnic--is linked with the issue of stability in a democratic system. There are 2 models of multiculturalism and corresponding public policy approaches. 1 model emphasizes the role of the political processes in Australian ethnic relations and sees ethnic structures (political, social, economic) as legitimate but separate interest groups, each having the exclusive responsibility for the realization of ethnic goals. The leading feature of this model is the structural fragmentation of Australian society into parallel segments of varying degrees of exclusiveness each with its own "ethnic" label. The 2nd model stresses the priority of the wholeness and welfare of the entire society. It assumes that a society based on satisfaction of individual needs through voluntary exchange is fertile ground for cultural enrichment. The goal is cohesion and unity in living together in Australia, seen as of central concern and consistent with the ideals of intercultural understanding and improved communication. The model assumes that the culture must be seen as a living, dynamic, changing, and interacting set of life patterns. The author prefers the 2nd model which stresses that the future vision of a multicultural Australia must be a shared one because only then can cultural diversity and national cohesion coexist within the 1 economic and political unit.

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

  15. Estimating the financial risks of Andropogon gayanus to greenhouse gas abatement projects in northern Australia

    International Nuclear Information System (INIS)

    Financial mechanisms such as offsets are one strategy to abate greenhouse gas emissions, and the carbon market is expanding with a growing demand for offset products. However, in the case of carbon offsets, if the carbon is released due to intentional or unintentional reversal through environmental events such as fire, the financial liability to replace lost offsets will likely fall on the provider. This liability may have implications for future participation in programmes, but common strategies such as buffer pool and insurance products can be used to minimize this liability. In order for these strategies to be effective, an understanding of the spatial and temporal distributions of expected reversals is needed. We use the case study of savanna burning, an approved greenhouse gas abatement methodology under the Carbon Farming Initiative in Australia, to examine potential risks to carbon markets in northern Australia and quantify the financial risks. We focus our analysis on the threat of Andropogon gayanus (gamba grass) to savanna burning due to its documented impacts of increased fuel loads and altered fire regimes. We assess the spatial and financial extent to which gamba grass poses a risk to savanna burning programmes in northern Australia. We find that 75% of the eligible area for savanna burning is spatially coincident with the high suitability range for gamba grass. Our analysis demonstrates that the presence of gamba grass seriously impacts the financial viability of savanna burning projects. For example, in order to recuperate the annual costs of controlling 1 ha of gamba grass infestation, 290 ha of land must be enrolled in annual carbon abatement credits. Our results show an immediate need to contain gamba grass to its current extent to avoid future spread into large expanses of land, which are currently profitable for savanna burning. (letter)

  16. "Sydney sandstone": Heritage Stone from Australia

    Science.gov (United States)

    Cooper, Barry; Kramar, Sabina

    2014-05-01

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

  17. Myocardial perfusion SPECT in Australia: processing parameters

    International Nuclear Information System (INIS)

    Despite clear guidelines provided by the SNM and the ASNC for acquisition parameters in myocardial perfusion SPECT, there is no universally accepted consensus on processing protocols for myocardial perfusion SPECT. This study is the second part of a self administered, anonymous questionnaire of current procedures employed for myocardial perfusion SPECT across Australia. The sampling frame comprised 136 Nuclear Medicine departments across Australia including all departments accredited by the ANZSNM. QGS is the quantitative software of choice in 58.9% (53/90) of departments (95% CI: 48.6% to 68.5%). Private clinics are 2.4 times more likely (RR) to use ECTb than other department types. Filtered backprojection is the reconstruction algorithm of choice in 71.7% (71/99) of departments (95% CI: 62.2% to 79.6%) while iterative reconstruction is employed in 16.2% (16/99) of departments (95% CI: 10.2% to 24.7%). Reconstruction is performed using 180 Deg of data in 83.8% (83/99) of departments (95% CI: 75.3% to 89.8%) while 360 Deg of data is reconstructed in 5.1% (5/99) of departments (95% CI: 2.2% to 11.3%). Pre filtering is employed in the reconstruction process in 58.0% (51/88) of departments (95% CI: 47.5% to 67.7%) while a post filter is employed in 39.8% (35/88) of departments (95% CI: 30.2% to 50.2%). There is evidence to suggest that there is widespread use of processing parameters that are either discordant where there are recommendations in the literature or counter-intuitive in the absence of documented guidelines. There is a requirement for investigation of the actual impact of these variations on the diagnostic utility of myocardial perfusion SPECT and a need for development of working guidelines for optimisation of processing protocols.

    Variation in weather and climate events impacts agriculture production processes, and profits across years. Therefore, seasonal rainfall prediction is an important factor for strategic and tactical decision making in agricultural, land and water resource management. This study aims to apply optimal data-driven techniques for fine resolution climate classification and forecasting over South-eastern Australia. Data were used in this study were included daily precipitation, maximum and minimum temperature data collected over 40 years from 107 weather stations in Southeast Australia acquired from the Bureau of Meteorology (BOM). Fuzzy-k means clustering techniques (FKM) were applied on one year weekly time series. Cluster centroids and memberships of rainfall and temperature weekly time series for one year period provide meaningful and insight into weather variability in time and space over the study. Stations are grouped based on their memberships in rainfall and temperature classes. The result showed that FKM is a useful method for trend analysis and pattern discovery in space and time. Outcomes indicate improvement in the climate classification of the area at the station level. An associate project is gathering higher spatial density on-farm data. This high-resolution climate data collected at the farm scale will be analyzed similarly in the future to improve spatial resolution of our classification. The second stage of this study consists of development of a fine-resolution forecasting model for predicting rainfall. FKM was applied on a metrics which included input and output time series to extract rules and relationships between them. After classification, rules were extracted within each class based on forecasting time, space and extreme climate events followed by effective sea surface temperature anomalies. These rules and a lookup table of input and output centroids were used for rainfall prediction in the form of weekly time series for the next six months. One

  20. The possibility of a commercial enrichment venture in Australia

    International Nuclear Information System (INIS)

    Uranium is Australia's most unexploited source of revenue. It is inevitable that nuclear energy will become the world's major source of electrical power in the next century. Australia possesses nearly 30% of the free world's known uranium reserves. It is therefore highly desirable that Australia should become a major influence in the nuclear fuel cycle. In this paper the possibility of a commercial enrichment venture in Australia will be discussed from the viewpoint of private enterprise. Firstly, previous Australian involvement in the nuclear industry will be outlined. Historical perspectives and the current status of the enrichment issue is reviewed. Then the prospects for a commercial enrichment venture is discussed in some detail and finally a scenario fro development is considered

    Full Text Available The European Union is a major player in the world economy and also the largest trading player on the global scene, accounting for about 20% of world imports and exports. The elimination of trade barriers within the EU confirmed its commitment to global trade liberalisation as it is an important part of multilateral trade negotiations. Apart from WTO trade agreements, the European Union concluded a number of bilateral trade agreements with certain countries and regions in the world. The aim of this paper is to present the EU-Australia trade relationship, Australia being an important trading partner of the EU. The trade flows between them includes both agricultural and non-agricultural products. The database that has been used is represented by the information published by the European Commission and the Australian Government. In conclusion, we found that both EU imports from Australia and EU exports to Australia are dominated by non-agricultural products.

  3. Australia's mandatory renewable energy target (MRET): an assessment

    International Nuclear Information System (INIS)

    In June 2004, the Prime Minister of Australia, John Howard, released the long-awaited government blueprint for the favoured policy direction for the country's energy sector, Securing Australia's Energy Future. In part this document was a response to a review of the operation of Australia's mandatory renewable energy target (MRET), a regime that started in April 2001. MRET was put under detailed scrutiny from March 2003 onwards by a four-person panel (the Tambling Committee), appointed by the Howard coalition (conservative) government, that received 248 detailed submissions and finally released its findings to the public in January 2004. This paper presents an overview of (i) the range of opinions on MRET presented to the Tambling Inquiry; (ii) the recommendations of that Committee; (iii) the final judgement on MRET enunciated in Securing Australia's Energy Future; and (iv) the response of the States

  4. The discovery and development of uranium in Australia

    International Nuclear Information System (INIS)

    The history of the discovery of Australia's uranium deposits is reviewed. The exploration can be conveniently divided into three periods - pre-1944, when the only significant discoveries were made by prospectors in South Australia at Radium Hill and Mount Painter; 1944-1960 and post-1967. The second period saw uranium discoveries in the Northern Territory and Queensland, most of which were made by prospectors using hand-held geiger counters and rewarded by the Australian Government. Since 1967 new deposits have been found in the Northern Territory, Queensland, South Australia and Western Australia by companies using maps, airborne radiometric surveys and sophisticated equipment. The step from the discovery of Mary Kathleen by prospectors to finding Roxby Downs by a combination of geophysical methods, geological concepts and deep drilling was a very big one

    Full Text Available There has been a high degree of economic and financial integration between Australia and New Zealand with free trade agreements linking the capital and labor markets. Given a strong economic relationship, business-cycle transmission is expected to exist between the two countries. By analyzing the shock-transmission channels via trade, monetary policy, and exchange rates between Australia and New Zealand we can infer that if Australia and New Zealand trade less, have more similar monetary policy structure, or have less similar economic structures they would have stronger economy correlation. The results also show that the highly integrated banking system between Australia and New Zealand is an additional avenue for shock transmission between both countries.

    The Australian Government established the National Dioxins Program (NDP) in 2001 to improve knowledge about levels of dioxins in Australia. The program aims to determine levels, assess the risks to Australians and the environment, and to consider appropriate management actions. Starting in mid 2001and completed in 2004, the studies constituted the largest survey of dioxin levels ever undertaken in Australia. The findings will contribute to debate on how to deal with dioxins in Australia, as well as helping to meet obligations under the Stockholm Convention on Persistent Organic Pollutants, which Australia ratified on 20 May 2004. These studies will also contribute to a better understanding about dioxins in the southern hemisphere. This paper provides a summary of the key findings of these studies and the risk assessments.

  7. Perceptions of Water Pricing during a Drought: A Case Study from South Australia

    2013-02-01

    Full Text Available This paper examines the perceptions of urban and regional water consumers in three areas of South Australia on the fairness of the water pricing system, the impact of increases in water pricing on households and pricing as a driver of water conservation. The study was conducted in 2009 during a time of severe drought and mandatory water restrictions. The results did not show a general aversion to all aspects of price increases but rather different sectors of the population were particularly resistant to different, specific aspects of water pricing. A state-wide water pricing policy in South Australia means that all consumers pay the same rate per volume of water consumed regardless of their location; yet in the regional study area, where it costs more for the service provider to supply the water, the respondents had stronger feelings that the price of water should be higher in places where it costs more to supply it. Generally, low income earners were less in favor of a block pricing system than higher income earners. The latter findings indicate a common lack of awareness around various aspects of water pricing. Some implications of the findings for water managers are outlined.

  8. Host-driven diversification of gall-inducing Acacia thrips and the aridification of Australia

    2007-01-01

    Full Text Available Abstract Background Insects that feed on plants contribute greatly to the generation of biodiversity. Hypotheses explaining rate increases in phytophagous insect diversification and mechanisms driving speciation in such specialists remain vexing despite considerable attention. The proliferation of plant-feeding insects and their hosts are expected to broadly parallel one another where climate change over geological timescales imposes consequences for the diversification of flora and fauna via habitat modification. This work uses a phylogenetic approach to investigate the premise that the aridification of Australia, and subsequent expansion and modification of arid-adapted host flora, has implications for the diversification of insects that specialise on them. Results Likelihood ratio tests indicated the possibility of hard molecular polytomies within two co-radiating gall-inducing species complexes specialising on the same set of host species. Significant tree asymmetry is indicated at a branch adjacent to an inferred transition to a Plurinerves ancestral host species. Lineage by time diversification plots indicate gall-thrips that specialise on Plurinerves hosts differentially experienced an explosive period of speciation contemporaneous with climatic cycling during the Quaternary period. Chronological analyses indicated that the approximate age of origin of gall-inducing thrips on Acacia might be as recent as 10 million years ago during the Miocene, as truly arid landscapes first developed in Australia. Conclusion Host-plant diversification and spatial heterogeneity of hosts have increased the potential for specialisation, resource partitioning, and unoccupied ecological niche availability for gall-thrips on Australian Acacia.

    The concept of receptivity is a new way of understanding the personal and social factors that affect a person living with and beyond cancer, and how these factors influence access to formal supportive care service provision and planning. This article contributes to new knowledge through applying the concept of receptivity to informal supportive cancer care in regional Australia. Literature indicates that a cancer diagnosis is a life-changing experience, particularly in regional communities, where survival rates are lower and there are significant barriers to accessing services. Heideggerian phenomenology informed the design of the study and allowed for a rich and nuanced understanding of participants lived experiences of informal supportive cancer care. These experiences were captured using in-depth interviews, which were subsequently thematically analysed. Nineteen participants were recruited from across regional Victoria, Australia. Participants self-reported a range of stages and types of cancer. Significantly, findings revealed that most participants were not referred to, and did not seek, formal supportive care. Instead, they were receptive to informal supportive care. Understanding receptivity and the role of anxiety and fear of death has implications for partners, family, community members, as well as professionals working with people with living with and beyond cancer.

    The number of people in Australia living with HIV is growing. This reflects a consistent rate of new HIV infections combined with an increased life expectancy of people with HIV. Dentists are ideally positioned to identify, manage and treat HIV-associated oral manifestations and have a responsibility to themselves and to their patients to be up-to-date with the evolving area of HIV and related issues. Those issues include medico-legal implications associated with HIV diagnosis and treatment. This article provides a review of the current clinical and medico-legal aspects of HIV in Australia. The oral manifestations of HIV can be divided into five categories: microbiological infections (fungal, bacterial and viral); oral neoplasms; neurological conditions; other oral conditions that may be associated with HIV infection; and oral conditions associated with HIV treatment. Current treatment options in the scope of general dental practice are outlined. Medico-legal issues related to the management of patients with HIV are explored, including rights of the patient regarding disclosure of HIV status; an algorithm for the management of a patient with signs or symptoms indicating possible HIV infection, including referral pathways; and an algorithm for dealing with patient management and referral issues.

    Dryland vegetation is very sensitive to climatic and anthropogenic pressures and prone to critical degradation thresholds which make rehabilitation efforts considerably difficult. In many dryland areas of Australia, the spatial structure of vegetation is tightly linked to overland flow redistribution through feedback mechanisms that are likely to exhibit this type of threshold behaviour. Disturbances can trigger erosion and substantial water losses by increasing landscape hydrological connectivity and damaging ecosystem function. In this study, we combine remote sensing observations with a modelling approach to analyse changes in ecosystem connectivity and the existence of threshold behaviour along a precipitation gradient in selected sites of the Mulga Lands Bioregion in Australia (250mm to 490mm annual average rainfall). Vegetation patterns are derived from high resolution remote sensing images, and Rainfall Use Efficiency estimated from precipitation data and MODIS vegetation indices for several plots across along this gradient. These data is used to model the evolution of landform and vegetation in order to analytically investigate the processes and possible triggering mechanisms for threshold behaviour. We find that disturbances can substantially increase the connectivity above a threshold that leads to severe degradation determined by loss of productivity and landscape functionality (e.g. rainwater use efficiency of the landscapes). However, both observations and modelling results suggest that sites with higher rainfall are more resilient to changes in surface connectivity, even if these changes are quite profound. The implications for ecosystem resilience and land management strategies are briefly discussed.

    High quality education programs are essential for preparing the next generation of Chinese medicine (CM) practitioners. Currently, training in CM occurs within differing health and education policy contexts. There has been little analysis of the factors influencing the form and status of CM education in different regions. Such a task is important for understanding how CM is evolving internationally and predicting future workforce characteristics. This paper compares the status of CM education in Australia and Hong Kong across a range of dimensions: historical and current positions in the national higher education system, regulatory context and relationship to the health system, and public and professional legitimacy. The analysis highlights the different ways in which CM education is developing in these settings, with Hong Kong providing somewhat greater access to clinical training opportunities for CM students. However, common trends and challenges shape CM education in both regions, including marginalisation from mainstream health professions, a small but established presence in universities, and an emphasis on biomedical research. Three factors stand out as significant for the evolution of CM education in Australia and Hong Kong and may have international implications: continuing biomedical dominance, increased competition between universities, and strengthened links with mainland China.

    Full Text Available Abstract – This chapter focuses upon two contrasting features of the linguistic situation in Australia. On the one hand, together with nationhood, the past hundred or so years have seen the evolution of a distinct national variety of English in Australia recognizable also outside Australia. On the other, Australia, though a young nation, has been continuously inhabited by the various Aborigine and Torre Strait Islander communities for thousands of years. These have traditionally spoken a wide variety of different languages, some of which of great interest to linguists due to their peculiarity. Increasingly, although the use of Aborigine languages has until very recently been in steady decline, since the 1950s in particular, diverse ethnic groups speaking a variety of languages, both European and Asian, have settled in Australia. The National Policy on Languages (1987 formally directed Australia towards multilingualism and the teaching of English as a first and second language is promoted together with that of Aborigine and community languages. Consequently, Australia has been one of the first nations to try to capitalise on its own linguistic diversity, both as a means of strengthening links with the outside world and as a way of promoting a multiethnic and multicultural society at home. Australia presents then an interesting case study for those working with discourse in immigration domains who are concerned with the way that language policy (or the lack of one may effect social harmony and serve not only as an indicator of the way that migrants are received and treated, but also a catalyst in itself for greater mutual respect.

    Public pedagogies in tourism and education in Australia suggest that food is a medium through which we learn more about each other’s cultures: in other words food is a pedagogy of multiculturalism. Drawing on a white Anglo Australian man’s memories of food in different intercultural encounters, this paper prises open the concept of eating the Other. There has been trenchant critique of food multiculturalism and the consuming cosmopolitan in Australia (Hage 1997; Probyn 2004; Duruz 2010). Thus...

    Understanding how health outcomes are spatially distributed represents a first step in investigating the scale and nature of environmental influences on health and has important implications for statistical power and analytic efficiency. Using Australian and French cohort data, this study aimed to describe and compare the extent of geographic variation, and the implications for analytic efficiency, across geographic units, countries and a range of cardiometabolic parameters (Body Mass Index (BMI) waist circumference, blood pressure, resting heart rate, triglycerides, cholesterol, glucose, HbA1c). Geographic clustering was assessed using Intra-Class Correlation (ICC) coefficients in biomedical cohorts from Adelaide (Australia, n = 3893) and Paris (France, n = 6430) for eight geographic administrative units. The median ICC was 0.01 suggesting 1% of risk factor variance attributable to variation between geographic units. Clustering differed by cardiometabolic parameters, administrative units and countries and was greatest for BMI and resting heart rate in the French sample, HbA1c in the Australian sample, and for smaller geographic units. Analytic inefficiency due to clustering was greatest for geographic units in which participants were nested in fewer, larger geographic units. Differences observed in geographic clustering across risk factors have implications for choice of geographic unit in sampling and analysis, and highlight potential cross-country differences in the distribution, or role, of environmental features related to cardiometabolic health.

    Global warming is an international problem. Multilateral actions agreed to under international treaties would be the most effective means of limiting global carbon dioxide emissions. Each country, however, would have some discretion in deciding how best to meet its obligations. In this paper, a potentially important `unilateral` action on the part of Australia, a carbon tax, is examined. When combined with a package of other measures, it may be argued that carbon taxation might be a beneficial policy measure even though actions by Australia would have only a small impact on global emissions. While the arguments may be developed in the Australian context they are relevant to industrial countries more generally. After considering Australia`s current situation with respect the emissions and international greenhouse obligations, the advantages and disadvantages of a carbon tax are reviewed. Based on some modelling work on the effects of introducing a carbon tax in Australia, including projections of impacts on carbon emissions, economic growth and employment, it is concluded that, with appropriate use of carbon tax revenues, there is a prima facie case for the unilateral introduction of carbon taxation in Australia.

    IMOS is a distributed set of equipment and data-information services which collectively contribute to meeting the needs of marine climate research in Australia. The observing system provides data in the open oceans around Australia out to a few thousand kilometres as well as the coastal oceans through 11 facilities (Argo Australia, Ships of Opportunity, Southern Ocean Time Series, Australian National Facility for Ocean Gliders, Autonomous Underwater Vehicle Facility, Australian National Mooring Network, Australian Coastal Ocean Radar Network, Australian Acoustic Tagging and Monitoring System, Facility for Automated Intelligent Monitoring of Marine Systems, eMarine Information Infrastructure and Satellite Remote Sensing) and 5 nodes (Blue Water, Great Barrier Reef Ocean Observing System, New South Wales IMOS, Southern Australia IMOS and Western Australia IMOS).The data are made available to researchers through the electronic Marine Information Infrastructure (eMII). Specifically, IMOS also incorporates a National Reference Station infrastructure (NRS) based on 9 stations in the coastal ocean around Australia. The NRS is (i) multi-disciplinary and integrated with the collection of over 60 marine parameters, (ii) modular, which allows for deployment with or without a surface signature, and (iii) versatilely based on regionally scaled logistics. After introducing the philosophy of IMOS and its implementation, the first results obtained through a suite of facilities will be illustrated across different nodes.

    The distinction between native and introduced flora within isolated land masses presents unique challenges. The geological and colonisation history of Australia, the world's largest island, makes it a valuable system for studying species endemism, introduction, and phylogeny. Using this strategy we investigated Australian cosmopolitan grasses belonging to the genus Cynodon. While it is believed that seven species of Cynodon are present in Australia, no genetic analyses have investigated the origin, diversity and phylogenetic history of Cynodon within Australia. To address this gap, 147 samples (92 from across Australia and 55 representing global distribution) were sequenced for a total of 3336bp of chloroplast DNA spanning six genes. Data showed the presence of at least six putatively introduced Cynodon species (C. transvaalensis, C. incompletus, C. hirsutus, C. radiatus, C. plectostachyus and C. dactylon) in Australia and suggested multiple recent introductions. C. plectostachyus, a species often confused with C. nlemfuensis, was not previously considered to be present in Australia. Most significantly, we identified two common haplotypes that formed a monophyletic clade diverging from previously identified Cynodon species. We hypothesise that these two haplotypes may represent a previously undescribed species of Cynodon. We provide further evidence that two Australian native species, Brachyachne tenella and B. convergens belong in the genus Cynodon and, therefore, argue for the taxonomic revision of the genus Cynodon.

  6. Australia's uranium resources and production in the world context

    International Nuclear Information System (INIS)

    Australia has 654 000 tonnes uranium (U) in Reasonably Assured Resources (RAR) recoverable at ≤US$40/kg U, which is the largest of all national resource estimates reported in this category. Australia also has the world's largest resources in RAR recoverable at ≤US$80/kg U, with 29% of world resources in this category. Other countries that have large resources in this category include Kazakhstan (19%), Canada (14%), South Africa (10%), Brazil (7%), Namibia (6%), Russian Federation (6%), and United States (5%). In 2000, the main developments in Australia's uranium mining industry were that production reached a record level of 8937 t U3O8 (7579 t U), and commercial operations commenced at the new in situ leach operation at Beverley during November. Australia's total production for 2000 was 27% higher than for 1999. Uranium oxide was produced at the Olympic Dam (4500 t U3O8), Ranger (4437 t U3O8) and Beverley operations, although production from Beverley for the year was not reported. Australia's share of the world's annual uranium production has increased steadily from about 10.8% (3,712 tonnes U) in 1995 to 21.9% in 2000. Throughout this period Australia has maintained its position as the world's second-largest producer of uranium, behind Canada

    Australia has a fossil record of penguins reaching back to the Eocene, yet today is inhabited by just one breeding species, the little penguin Eudyptula minor. The description of recently collected penguin fossils from the re-dated upper Miocene Port Campbell Limestone of Portland (Victoria), in addition to reanalysis of previously described material, has allowed the Cenozoic history of penguins in Australia to be placed into a global context for the first time. Australian pre-Quaternary fossil penguins represent stem taxa phylogenetically disparate from each other and E. minor, implying multiple dispersals and extinctions. Late Eocene penguins from Australia are closest to contemporaneous taxa in Antarctica, New Zealand and South America. Given current material, the Miocene Australian fossil penguin fauna is apparently unique in harbouring ‘giant penguins’ after they went extinct elsewhere; and including stem taxa until at least 6 Ma, by which time crown penguins dominated elsewhere in the southern hemisphere. Separation of Australia from Antarctica during the Palaeogene, and its subsequent drift north, appears to have been a major event in Australian penguin biogeography. Increasing isolation through the Cenozoic may have limited penguin dispersal to Australia from outside the Australasian region, until intensification of the eastwards-flowing Antarctic Circumpolar Current in the mid-Miocene established a potential new dispersal vector to Australia.

    Full Text Available Background The aim of newborn bloodspot screening (NBS is to identify rare genetic and non-genetic conditions in children soon after birth in order to commence therapies that prevent the development of progressive, serious, and irreversible disabilities. Universal NBS programmes have been implemented in most countries, with minor adaptations to target conditions most relevant to the local healthcare environment. Aims In this article, we describe the initiatives of international and Australian governments to develop policies to address the expansion of NBS in their healthcare systems. Methods We have reviewed published public policies and literature to formulate recommendations based on clinical, social, legal, and ethical principles to inform a national governance and policy framework for Australia. Results Australian policy makers have been slow to develop a coordinated plan. While the experience from other governments can guide our national policy, there are specific areas that require further consideration by Australian health experts. Key reforms involve the separation of policy and operational activities, multidisciplinary decision-making and oversight by the Australian Health Ministers’ Advisory Council for policy direction. Conclusion A formal national policy framework will guide the coordination of NBS services that can adapt to the needs of Australian children and families.

  9. Regulatory aspects of criticality control in Australia

    International Nuclear Information System (INIS)

    With the creation of Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) the Australian approach to criticality safety was revisited. Consistency with international best practices is required by the Act that created ARPANSA and this was applied to practices in criticality safety adopted in other countries. This required extensive regulatory efforts both in auditing the major Australian Nuclear Operator, Australian Nuclear Science and Technology Organisation (ANSTO), and assessing the existing in Australia criticality safety practices and implementing the required changes using the new legislative power of ARPANSA. The adopted regulatory approach is formulated through both the issued by ARPANSA licenses for nuclear installations (including reactors, fuel stores and radioactive waste stores) and the string of new regulatory documents, including the Regulatory Assessment Principles and the Regulatory Assessment Guidelines for criticality safety. The main features of the adopted regulation include the requirements of independent peer-review, ongoing refresher training coupled with annual accreditation and the reliance on the safe design rather than on an administrative control.

    The “Black Saturday” fires were a set of devastating bushfires that burned across the Australian state of Victoria on Saturday the 7th of February 2009 killing 173 people. The fires continued into March when rain and cooler conditions allowed the fires to be extinguished. Smoke plumes from the Black Saturday fires were transported south eastwards eluding local ground-based remote sensing FTIR spectrometers, but were captured by a number of satellite-based sensors. OMI UV-aerosol index data show that smoke from the first intense fires separated from subsequent plumes and was transported to the north of New Zealand where it stayed for over a week before moving west across northern Australia and dissipating over the Indian Ocean in early March. Here we present an analysis of the emissions from the Black Saturday fires including total emissions estimates for a number of trace gases and a study of the aging of the smoke emitted from the first days of the fires.

    A physiotherapist is part of the multidisciplinary team in most intensive care units in Australia. Physiotherapists are primary contact practitioners and use a comprehensive multisystem assessment that includes the respiratory, cardiovascular, neurological, and musculoskeletal systems to formulate individualized treatment plans. The traditional focus of treatment has been the respiratory management of both intubated and spontaneously breathing patients. However, the emerging evidence of the longstanding physical impairment suffered by survivors of intensive care has resulted in physiotherapists re-evaluating treatment priorities to include exercise rehabilitation as a part of standard clinical practice. The goals of respiratory physiotherapy management are to promote secretion clearance, maintain or recruit lung volume, optimize oxygenation, and prevent respiratory complications in both the intubated and spontaneously breathing patient. In the intubated patient, physiotherapists commonly employ manual and ventilator hyperinflation and positioning as treatment techniques whilst in the spontaneously breathing patients there is an emphasis on mobilization. Physiotherapists predominantly use functional activities for the rehabilitation of the critically ill patient in intensive care. While variability exists between states and centers, Australian physiotherapists actively treat critically ill patients targeting interventions based upon research evidence and individualized assessment. A trend toward more emphasis on exercise rehabilitation over respiratory management is evident. PMID:22807651

    2016-03-01

    Attempts at medicinal cannabis law reform in Australia are not new. However, in historical perspective 2015 and 2016 will be seen as the time when community debate about legalisation of medicinal cannabis reached a tipping point in a number of Australian jurisdictions and when community impetus for change resulted in major reform initiatives. In order to contextualise the changes, the August 2015 Report of the Victorian Law Reform Commission (VLRC) and then the Access to Medicinal Cannabis Bill 2015 (Vic) introduced in December 2015 into the Victorian Parliament by the Labor Government are scrutinised. In addition, this editorial reviews the next phase of developments in the course of 2015 and 2016, including the Commonwealth Narcotic Drugs Amendment Act 2016 and the Queensland Public Health (Medicinal Canna- bis) Bill 2016. It identifies the principal features of the legislative initiatives against the backdrop of the VLRC proposals. It observes that the principles underlying the Report and the legislative developments in the three Australian jurisdictions are closely aligned and that their public health approach, their combination of evidence-based pragmatism, and their carefully orchestrated checks and balances against abuse and excess constitute a constructive template for medicinal cannabis law reform.

  13. National QA in BreastScreen Australia

    International Nuclear Information System (INIS)

    Full text: BreastScreen Australia was established in 1990 as a National Programme for the Early Detection of Breast Cancer, with the aim of reducing breast cancer mortality and morbidity. The programme is offered free of charge to all women over 40 years of age but targets women aged 50 to 69 years, and covers mammography screening and multidisciplinary assessment up to tissue diagnosis. It is fully funded by the Australian Commonwealth, State and Territory governments. National Accreditation Guidelines were developed in 1991, as it was agreed from the start of the programme that, in order to achieve high quality outcomes, services operating within the programme would need to be accredited. Accreditation requirements have since undergone several revisions, and the current National Accreditation Standards cover all aspects of service operation necessary to achieve accreditation as part of BreastScreen Australia. There have also been some changes to the accreditation process which is overseen by a multidisciplinary National Quality Management Committee (NQMC). The service delivery model is that of multiple mammography screening units attached to a single or several multi-disciplinary assessment centres, forming a Screening and Assessment Service (SAS). Multiple SASs are linked under the relevant State/Territory Coordination Unit, and these form part of the national programme. As part of accreditation, the SASs are visited by teams which evaluate all facets of the service including facilities, equipment, staffing, clinical practice, data management and outcomes. The current accreditation standards are clustered under 10 key outcome areas, considered equally important to achieve programme goals. These outcome areas are: cancer detection, participation, access, information, recall, assessment, counselling/support, data, timeliness and management. Quality assurance is both quantitative and qualitative. On the basis of the likelihood of not meeting a given standard and

  14. Radiation doses from mammography in Australia

    International Nuclear Information System (INIS)

    During 1989-90 the Australian Radiation Laboratory conducted a postal survey of at least 90% of the mammographic facilities in Australia. The primary aim of the survey was to measure the mean glandular dose (MGD) and the X-ray beam half value layer (HVL) for a typical mammograph. The MGD and HVL were measured with a specially designed tissue equivalent monitor. In all, 258 mammographic centres were surveyed. It was found that for centres using film-screen imaging, the average mean glandular dose was 1.83 mGy for centres using grids and 0.84 mGy for centres not using grids. In addition to the MGD and HVL, comprehensive statistical information was collected and data is presented on the types of equipment and techniques used, the number and age of patients and demographic distribution of centres. Results indicate that the use of a grid is the major factor determining dose and several other factors appear to have minor effects. In view of the distribution of MGD, it is recommended that the mean glandular dose per image, for a 5 cm compressed breast thickness, should not exceed 2.0 mGy when a grid is used and 1.0 mGy without a grid. 63 refs., 11 tabs., 15 figs

    This paper reported on a study that evaluated the energy consumption of cotton gins used in Australia. The average electricity use is 52.3 kWh per bale. In practicality, the electricity consumption for different gins is correlated linearly with the bale numbers produced. The cost of electricity is therefore important in cotton ginning operations. The power factor in all the gins monitored in this study was greater than 0.85. The study showed that the use of gas dryers was highly influenced by the cotton moisture and regulated drying temperature. In general, electricity and gas consumption comprised 61 and 39 per cent of total energy use respectively. The study showed that 60.38 kg of carbon dioxide are emitted for ginning each bale of cotton. This paper described a newly developed method for monitoring the energy performance in cotton gins. Detailed monitoring and analysis carried out at 2 gin sites revealed that electricity consumption is not influenced much by changes in trash content in the module, degree of moisture and lint quality. However, the cotton variety influences the energy consumption. Cotton handling constituted nearly 50 per cent of the power used in both gins.

    The study examines trends in bicycling fatalities reported to the Australian police between 1991 and 2013. Trends were estimated using Poisson regression modelling. Overall, cycling fatalities decreased by 1.9% annually between 1991 and 2013. However, while deaths following multivehicle crashes decreased at a rate of 2.9% per annum (95% CI -4.0% to -1.8%), deaths from single vehicle crashes increased by 5.8% per annum (95% CI 4.1% to 7.5%). Over the study period, the average age of cyclists who died in single vehicle crashes (45.3 years, 95% CI 41.5 to 49.1) was significantly higher than cyclists who died in multivehicle crashes (36.2 years, 95% CI 34.7 to 37.7). The average age of deceased cyclists increased significantly for both types of crashes. The observed increase in single vehicle crashes need to be closely monitored in Australia and internationally. In-depth studies are needed to investigate the circumstances of fatal single bicycle crashes in order to develop appropriate countermeasures. PMID:26180104

    We have surveyed six distinct `empty fields' using the Australia TelescopeCompact Array in an ultra-compact configuration with the aim of imaging, with ahigh brightness sensitivity, any arcmin-scale brightness-temperatureanisotropies in the background radio sky. The six well-separated regions wereobserved at a frequency of 8.7 GHz and the survey regions were limited by theATCA primary beams which have a full width at half maximum of 6 arcmin at thisfrequency; all fields were observed with a resolution of 2 arcmin and an rmsthermal noise of 24 microJy/beam. After subtracting foreground confusiondetected in higher resolution images of the fields, residual fluctuations inStokes I images are consistent with the expectations from thermal noise andweaker (unidentified) foreground sources; the Stokes Q and U images areconsistent with expectations from thermal noise. Within the sensitivity of our observations, we have no reason to believe thatthere are any Sunyaev-Zeldovich holes in the microwave sky surveyed. Assumi...

  18. Towards understanding hydroclimatic change in Victoria, Australia – preliminary insights into the "Big Dry"

    2010-03-01

    Full Text Available Since the mid-1990s the majority of Victoria, Australia, has experienced severe drought conditions (i.e. the "Big Dry" characterized by streamflow that is the lowest in approximately 80 years of record. While decreases in annual and seasonal rainfall totals have also been observed, this alone does not seem to explain the observed reduction in flow. In this study, we investigate the large-scale climate drivers for Victoria and demonstrate how these modulate the regional scale synoptic patterns, which in turn alter the way seasonal rainfall totals are compiled and the amount of runoff per unit rainfall that is produced. The hydrological implications are significant and illustrate the need for robust hydrological modelling, that takes into account insights into physical mechanisms that drive regional hydroclimatology, in order to properly understand and quantify the impacts of climate change (natural and/or anthropogenic on water resources.

    The drift history of Gondwana following the break-up of Rodinia (or perhaps Pannotia) to the amalgamation into Pangaea has great implications in many disciplines in Earth sciences, but remains largely unknown. Among the apparent polar wander (APW) paths published for Gondwana in the last few decades, large discrepancies exist (sometimes up to thousands of kilometres). The mid Palaeozoic segment of the APW path is particularly problematic, and two primary schools of thought arise. Some authors...

    country for overseas-qualified dentists. Migrant dentists arrive from contrasting social and cultural backgrounds, and these contrasts can be somewhat more pronounced in dentists from developing countries. To date, there is no evidence available regarding the cultural adaptation process of overseas-qualified dentists in Australia or elsewhere. What does this paper add? This study provides evidence to support the argument that the cultural adaptation process of overseas-qualified dentists in Australia can be viewed as a continuum state, where the individual learns to adapt to the people, language and lifestyle in Australia. The ongoing role of family and friends is primary to a successful transition process. Our research also identifies the positive role played by community and organisational structures, such as universities and public sector employment schemes. What are the implications for practitioners? A potential implication for policy makers is to focus on the positive roles played by organisational structures, particularly universities and the public sector. This can inform more supportive migration policy, as well as strengthen the role these organisations play in providing support for overseas-qualified dentists, thus enabling them to integrate more successfully into Australia's health care system, economy and society.

    Full Text Available Peter J Mayne International Lyme and Associated Diseases Society, Bethesda, MD, USA The author is a member of the International Lyme and Associated Diseases Society (ILADSBackground: Lyme disease (LD is an emerging infectious disease in Australia. There has been controversy regarding endemic lyme disease in the country for over 20 years. Borrelia burgdorferi sensu stricto (Bbss and sensu lato (Bbsl are closely related spirochetal species that are the causative agents of LD in humans. Clinical transmission of this tick-borne disease is marked by a characteristic rash known as erythema migrans (EM. This study employed molecular techniques to demonstrate the spirochetal agent of Lyme disease isolated from EM biopsies of patients in Australia and then investigate their genetic diversity.Methods: Four patients who presented to the author's practice over a one-year period from mid 2010 to mid 2011 returned positive results on central tissue biopsy of EM lesions using polymerase chain reaction (PCR analysis. The findings were confirmed by DNA sequencing, and basic local alignment search tool (BLAST analysis was then used to genetically characterize the causative organisms.Results: Three isolates were identified as Bbss that lay genotypically between strains B31 and ZS7 and were then characterized as strain 64b. One of the three isolates though may have similarity to B. bissettii a Bbsl. The fourth isolate was more appropriately placed in the sensu lato group and appeared to be similar, but not identical to, a B. valaisiana-type isolate. In this study, a central biopsy taken within 6 days of infection was used instead of conventional sampling at the leading edge, and the merits of this are discussed.Conclusion: These patients acquired infection in Australia, further proving endemic LD on the continent. Central biopsy site of EM is a useful tool for PCR evaluation. BLAST searches suggest a genetic diversity of B. burgdorferi, which has implications

  6. Carbonate hosted gold deposit in Tasmania, Australia

    International Nuclear Information System (INIS)

    Full text: This study uses elemental and isotopic composition of carbonates associated with gold from Henty and Beaconsfield in Tasmania, Australia, to illustrate source of gold-bearing fluids, salinity, temperature and dissolution and reprecipitation of carbonate. The Beaconsfield and Henty gold mines are located in northern and western Tasmania respectively. Gold mineralisation in Beaconsfield occurs within the quartz-carbonate Tasmania Reef (Lower to Middle Palaeozoic sequence, Hills, 1998). The Henty gold mine is located at the base of the Cambrian Tyndall Group (volcano-sedimentary succession, White and McPhie, 1996) close to Henty Fault. Gold in carbonate samples from Henty ranges from 7.7 to 9360 ppm and in Beaconsfield ranges from 0.01 to 434 ppm. The amount of carbonate in samples from Henty and Beaconsfield gold mines varies from approximately 24 to 99.8%. Bivariate plot of Ca relative to total amounts of Mg, Fe and Mn illustrates that the major carbonate minerals at Beaconsfield and Henty gold mines are magnesian ankerite and calcite. The difference in carbonate mineralogy, at Henty and Beaconsfield gold mines, is attributed to the composition of fluids responsible for carbonate alteration. Gold and magnesium in Beaconsfield ankerite are derived from the leaching of Cambrian ultramafic rocks during the Devonian by the passage of meteoric fluids through tectonically affected Ordovician carbonates (Rao and Adabi, 1999). The total concentration of Fe and Mn are low (0.5 to 2%) in Henty and high (1 to 17.5%) in Beaconsfield ankerite, possibly due to oxidising conditions at Henty and reducing conditions at Beaconsfield gold mines during gold mineralisation. Variation of Sr values between Beaconsfield ankerite and Henty calcite is related to dissolution of limestone that increase Sr concentrations in gold mineralising fluids. Na values in both Beaconsfield (20 to 1100 ppm) and Henty carbonates (25 to 1650 ppm) suggest low salinity fluids responsible for gold

    2010-12-01

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

    Full Text Available OBJECTIVES: To estimate prevalence of chronic conditions among patients seeing a general practitioner (GP, patients attending general practice at least once in a year, and the Australian population. DESIGN SETTING AND PARTICIPANTS: A sub-study of the BEACH (Bettering the Evaluation and Care of Health program, a continuous national study of general practice activity conducted between July 2008 and May 2009. Each of 290 GPs provided data for about 30 consecutive patients (total 8,707 indicating diagnosed chronic conditions, using their knowledge of the patient, patient self-report, and patient's health record. MAIN OUTCOME MEASURES: Estimates of prevalence of chronic conditions among patients surveyed, adjusted prevalence in patients who attended general practice at least once that year, and national population prevalence. RESULTS: Two-thirds (66.3% of patients surveyed had at least one chronic condition: most prevalent being hypertension (26.6%, hyperlipidaemia (18.5%, osteoarthritis (17.8%, depression (13.7%, gastro-oesophageal reflux disease (11.6%, asthma (9.5% and Type 2 diabetes (8.3%. For patients who attended general practice at least once, we estimated 58.8% had at least one chronic condition. After further adjustment we estimated 50.8% of the Australian population had at least one chronic condition: hypertension (17.4%, hyperlipidaemia (12.7%, osteoarthritis (11.1%, depression (10.5% and asthma (8.0% being most prevalent. CONCLUSIONS: This study used GPs to gather information from their knowledge, the patient, and health records, to provide prevalence estimates that overcome weaknesses of studies using patient self-report or health record audit alone. Our results facilitate examination of primary care resource use in management of chronic conditions and measurement of prevalence of multimorbidity in Australia.

  9. Will Wallace's Line Save Australia from Avian Influenza?

    Directory of Open Access Journals (Sweden)

    Leo Joseph

    2008-12-01

    Full Text Available Australia is separated from the Asian faunal realm by Wallace's Line, across which there is relatively little avian migration. Although this does diminish the risk of high pathogenicity avian influenza of Asian origin arriving with migratory birds, the barrier is not complete. Migratory shorebirds, as well as a few landbirds, move through the region on annual migrations to and from Southeast Asia and destinations further north, although the frequency of infection of avian influenza in these groups is low. Nonetheless, high pathogenicity H5N1 has recently been recorded on the island of New Guinea in West Papua in domestic poultry. This event increases interest in the movements of birds between Wallacea in eastern Indonesia, New Guinea, and Australia, particularly by waterbirds. There are frequent but irregular movements of ducks, geese, and other waterbirds across Torres Strait between New Guinea and Australia, including movements to regions in which H5N1 has occurred in the recent past. Although the likelihood of avian influenza entering Australia via an avian vector is presumed to be low, the nature and extent of bird movements in this region is poorly known. There have been five recorded outbreaks of high pathogenicity avian influenza in Australian poultry flocks, all of the H7 subtype. To date, Australia is the only inhabited continent not to have recorded high pathogenicity avian influenza since 1997, and H5N1 has never been recorded. The ability to map risk from high pathogenicity avian influenza to Australia is hampered by the lack of quantitative data on the extent of bird movements between Australia and its northern neighbors. Recently developed techniques offer the promise to fill this knowledge gap.

  10. Australia's Uranium and thorium resources and their global significance

    International Nuclear Information System (INIS)

    Full text: Full text: Australia's world-leading uranium endowment appears to result from the emplacement of uranium enriched felsic igneous rocks in three major periods during the geological evolution of the continent. Australia has over 27% of the world's total reasonably assured uranium resources (RAR) recoverable at < US$80/kgU (which approximates recent uranium spot prices). Olympic Dam is the largest known uranium deposit, containing approximately 19% of global RAR (and over 40% of global inferred resources) recoverable at < US$80/kg U; the uranium is present at low concentrations and the viability of its recovery is underpinned by co-production of copper and gold. Most of Australia's other identified resources are within Ranger, Jabiluka, Koongarra, Kintyre and Yeelirrie, the last four of which are not currently accessible for mining. In 2004, Australia's three operating uranium mines - Ranger, Olympic Dam, and Beverley -produced 22% of global production. Canada was the only country to produce more uranium (29%) and Kazakhstan (9%) ranked third. Considerably increased uranium production has been recently foreshadowed from Australia (through developing a large open pit at Olympic Dam), Canada (mainly through opening of the Cigar Lake mine), and Kazakhstan (developing several new in situ leach mines). These increases should go a long way towards satisfying demand from about 2010. Olympic Dam has sufficient resources to sustain such increased production over many decades. Thorium is expected to be used in some future generations of nuclear reactors. Australia also has major (but incompletely quantified) resources of this commodity, mainly in heavy mineral sands deposits and associated with alkaline igneous rocks. It is inevitable that the international community will be looking increasingly to Australia to sustain its vital role in providing fuels for future nuclear power generation, given its world-leading identified resources, considerable potential for new

    King brown snakes or mulga snakes (Pseudechis australis) are the largest and among the most dangerous and wide-ranging venomous snakes in Australia and New Guinea. They occur in diverse habitats, are important predators, and exhibit considerable morphological variation. We infer the relationships and historical biogeography of P. australis based on phylogenetic analysis of 1,249 base pairs from the mitochondrial cytochrome b, NADH dehydrogenase subunit 4 and three adjacent tRNA genes using Bayesian, maximum-likelihood, and maximum-parsimony methods. All methods reveal deep phylogenetic structure with four strongly supported clades comprising snakes from New Guinea (I), localities all over Australia (II), the Kimberleys of Western Australia (III), and north-central Australia (IV), suggesting a much more ancient radiation than previously believed. This conclusion is robust to different molecular clock estimations indicating divergence in Pliocene or Late Miocene, after landbridge dispersal to New Guinea had occurred. While members of clades I, III and IV are medium-sized, slender snakes, those of clade II attain large sizes and a robust build, rendering them top predators in their ecosystems. Genetic differentiation within clade II is low and haplotype distribution largely incongruent with geography or colour morphs, suggesting Pleistocene dispersal and recent ecomorph evolution. Significant haplotype diversity exists in clades III and IV, implying that clade IV comprises two species. Members of clade II are broadly sympatric with members of both northern Australian clades. Thus, our data support the recognition of at least five species from within P. australis (auct.) under various criteria. We discuss biogeographical, ecological and medical implications of our findings.

    2016-07-01

    Purpose The paper aims to explore the beliefs of doctors in leadership roles of the concept of "the dark side", using data collected from interviews carried out with 45 doctors in medical leadership roles across Australia. The paper looks at the beliefs from the perspectives of doctors who are already in leadership roles themselves; to identify potential barriers they might have encountered and to arrive at better-informed strategies to engage more doctors in the leadership of the Australian health system. The research question is: "What are the beliefs of medical leaders that form the key themes or dimensions of the negative perception of the 'dark side'?". Design/methodology/approach The paper analysed data from two similar qualitative studies examining medical leadership and engagement in Australia by the same author, in collaboration with other researchers, which used in-depth semi-structured interviews with 45 purposively sampled senior medical leaders in leadership roles across Australia in health services, private and public hospitals, professional associations and health departments. The data were analysed using deductive and inductive approaches through a coding framework based on the interview data and literature review, with all sections of coded data grouped into themes. Findings Medical leaders had four key beliefs about the "dark side" as perceived through the eyes of their own past clinical experience and/or their clinical colleagues. These four beliefs or dimensions of the negative perception colloquially known as "the dark side" are the belief that they lack both managerial and clinical credibility, they have confused identities, they may be in conflict with clinicians, their clinical colleagues lack insight into the complexities of medical leadership and, as a result, doctors are actively discouraged from making the transition from clinical practice to medical leadership roles in the first place.

Food security also affects Australia and New Zealand's status as premier food exporting nations and the health and wellbeing of the Australasian population. Australia is uniquely positioned to help build a resilient food value chain and support programs aimed at addressing existing and emerging food security challenges. The Australian food governance system is fragmented and less transparent, being largely in the hands of government and semi-governmental regulatory authorities. The high level of consumer trust in Australian food governance suggests that this may be habitual and taken for granted, arising from a lack of negative experiences of food safety. In New Zealand the Ministry of Primary Industries regulates food safety issues. To improve trade and food safety, New Zealand and Australia work together through Food Standards Australia New Zealand (FSANZ) and other co-operative agreements. Although the potential risks to the food supply are dynamic and constantly changing, the demand, requirement and supply for providing safe food remains firm. The Australasian food industry will need to continually develop its system that supports the food safety program with the help of scientific investigations that underpin the assurance of what is and is not safe. The incorporation of a comprehensive and validated food safety program is one of the total quality management systems that will ensure that all areas of potential problems are being addressed by industry.

    The historical literature suggests that in Australia, the domestic cat (Felis catus) had a European origin [~200 years before present (ybp)], but it is unclear if cats arrived from across the Asian land bridge contemporaneously with the dingo (4000 ybp), or perhaps immigrated ~40000 ybp in association with Aboriginal settlement from Asia. The origin of cats in Australia is important because the continent has a complex and ancient faunal assemblage that is dominated by endemic rodents and marsupials and lacks the large placental carnivores found on other large continents. Cats are now ubiquitous across the entire Australian continent and have been implicit in the range contraction or extinction of its small to medium sized (<3.5kg) mammals. We analyzed the population structure of 830 cats using 15 short tandem repeat (STR) genomic markers. Their origin appears to come exclusively from European founders. Feral cats in continental Australia exhibit high genetic diversity in comparison with the low diversity found in populations of feral cats living on islands. The genetic structure is consistent with a rapid westerly expansion from eastern Australia and a limited expansion in coastal Western Australia. Australian cats show modest if any population structure and a close genetic alignment with European feral cats as compared to cats from Asia, the Christmas and Cocos (Keeling) Islands (Indian Ocean), and European wildcats (F. silvestris silvestris).

    In this paper,the author tries to give an account of the historical change of the Chinese community in Australia,hoping to sum up the basic pattern and structure of the Chinese community in Australia,as wel as the historical contributions the Chinese Australians has made to promote Sino-Australian friendship and the prosperity of the two countries. The paper can be divided into three parts. At the beginning,the author makes a brief introduction to the background of the formation of the Chinese community in Australia and the living condition of the Chinese Australians from 1848 to 1901. Later,the author explores the social state of the Chinese Australians under the White Australia Policy,with the intention to show the spirit of self-improvement of the Chinese. Then,at the end of the paper,the author points out the great contribution the Chinese Australians made not only for the motherland but for Australia,hoping to strengthen the cooperation and exchange.

  16. How should Australia regulate voluntary euthanasia and assisted suicide?

    White, Ben; Willmott, Lindy

    2012-12-01

    This article invites consideration of how Australia should regulate voluntary euthanasia and assisted suicide. It attempts to pose this question as neutrally as possible, acknowledging that both prohibition and legalisation of such conduct involve decisions about regulation. It begins by charting the wider field of law at the end of life, before considering the repeated, but ultimately unsuccessful, attempts at law reform in Australia. The situation in Australia is contrasted with permissive jurisdictions overseas where voluntary euthanasia and/or assisted suicide are lawful. The authors consider the arguments for and against legalisation of such conduct along with the available empirical evidence as to what happens in practice both in Australia and overseas. The article concludes by outlining a framework for deliberating on how Australia should regulate voluntary euthanasia and assisted suicide. It asks a threshold question of whether such conduct should be criminal acts (as they presently are), the answer to which then leads to a range of possible regulatory options. PMID:23431857

  17. Uranium Stakeholder Engagement in Northern Australia

    International Nuclear Information System (INIS)

    Uranium has been mined in the Northern Territory of Australia more or less continuously since 1949. Most of these mines have been located on Aboriginal land, although in many cases Native Title has only been recently established and the rights of the Traditional Owners finally acknowledged. In earlier days consultation with the Traditional Owners was generally unheard of and few sites were rehabilitated when mining ceased. However, leading practice in modern mining, including uranium mining, requires that these two issues are paid particular attention, whether it be for development and operation of current mines or the remediation of legacy sites. The paper presents two brief case studies in relation to stakeholder engagement developed in the Alligator Rivers Region uranium field of Australia’s Northern Territory. The subject of the first case study, the South Alligator valley, was subject to intensive prospecting and exploration which resulted in the development of 13 small uranium mines between 1955 and 1964. The operations were abandoned and the area returned to being a cattle ranch. In 1987 the valley lay within an area that was incorporated into the World Heritage-listed Kakadu National Park. In 1996 the Gunlom Land Trust, an association of traditional owners, was granted native title to the area under the Commonwealth’s Northern Territory Land Rights Act (1976). The new owners immediately leased the land back to the Commonwealth Government for continued use as a National Park. A condition of that lease was that all former mine sites and associated workings would be rehabilitated by 2015. The paper describes the comprehensive consultation process involving all stakeholders that was developed for this programme; and goes on to describe the programme of remediation works to date and the situation as of 2009. The second case history deals with the consultation process developed by one Government agency as it works with Traditional Owners and other

  18. Topographic relationships for design rainfalls over Australia

    Design rainfall statistics are the primary inputs used to assess flood risk across river catchments. These statistics normally take the form of Intensity-Duration-Frequency (IDF) curves that are derived from extreme value probability distributions fitted to observed daily, and sub-daily, rainfall data. The design rainfall relationships are often required for catchments where there are limited rainfall records, particularly catchments in remote areas with high topographic relief and hence some form of interpolation is required to provide estimates in these areas. This paper assesses the topographic dependence of rainfall extremes by using elevation-dependent thin plate smoothing splines to interpolate the mean annual maximum rainfall, for periods from one to seven days, across Australia. The analyses confirm the important impact of topography in explaining the spatial patterns of these extreme rainfall statistics. Continent-wide residual and cross validation statistics are used to demonstrate the 100-fold impact of elevation in relation to horizontal coordinates in explaining the spatial patterns, consistent with previous rainfall scaling studies and observational evidence. The impact of the complexity of the fitted spline surfaces, as defined by the number of knots, and the impact of applying variance stabilising transformations to the data, were also assessed. It was found that a relatively large number of 3570 knots, suitably chosen from 8619 gauge locations, was required to minimise the summary error statistics. Square root and log data transformations were found to deliver marginally superior continent-wide cross validation statistics, in comparison to applying no data transformation, but detailed assessments of residuals in complex high rainfall regions with high topographic relief showed that no data transformation gave superior performance in these regions. These results are consistent with the understanding that in areas with modest topographic relief, as

    Science.gov (United States)

    Kessell, Stephen R.; Good, Roger B.; Hopkins, Angas J. M.

    1984-05-01

    This paper describes the development and implementation of PREPLAN, A Pristine Environment Planning Language and Simulator, for two conservation areas in Australia, Kosciusko National Park (New South Wales) and Tutanning Nature Reserve (Western Australia). PREPLAN was derived from the North American gradient modeling systems and the Forest Planning Language and Simulator (FORPLAN), but includes unique characteristics not previously available. PREPLAN includes an integrated resource management data base, modules for predicting site-specific vegetation, fuels, animals, fire behavior, and fire effects, and an English language instruction set. PREPLAN was developed specifically to provide available information and understanding of ecosystems to managers in a readily accessible and usable form, and to provide the motivation to conduct additional required research projects. An evaluation of the system's advantages and limitations is presented, and the way the utilization of such systems is improving natural area decision making throughout Australia is discussed.

  1. New developments on the uranium sector in Australia

    International Nuclear Information System (INIS)

    Australia is one of the richest countries as far as uranium is concerned. The Jabiluka deposit alone is considered to be the largest single uranium deposit of the Western world. The overall known assured uranium reserves in Australia amount to 465.000 tons U3O8 at cost ranges between 15 and 30 US Dollar per pound U3O8, i.e. approximately 21% of the known world reserves. Most of the Australien uranium ore is of relatively high grade and nearly all of it could be mined from open pit. At this stage Mary Kathleen in Queensland is the only producing uranium mine in Australia. The actual political attitude of the Australian government prevents the Australian uranium industry from beeing further developed. (orig.) 891 HP/orig. 892 MKO

  2. Buddhism in Australia: An Emerging Field of Study

    Directory of Open Access Journals (Sweden)

    Anna Halafoff

    2015-02-01

    Full Text Available In 2006, Paul D. Numrich (2008 posed the question of whether contemporary scholarship on North American Buddhism constituted a distinct "field of study" and identified several factors that defined both academic disciplines and fields. This paper applies Numrich's criteria to the study of Buddhism in Australia, in its multiple and diverse forms, suggesting that it is an emerging field of study. While there has been an increase in historical, anthropological, and sociological scholarship in recent years, a comprehensive analysis of Buddhism in Australia, and particularly its impact on Australian life and culture, is yet to be conducted. This paper argues that such a study is both timely and necessary, given that Buddhism is the second largest religion in Australia, and we appear to be entering an "Asian century."

    This presentation tracks the development of the therapeutic application of radiation in Australia. Within six months of Roentgen's discovery, the Crooke's x-ray tube and later a radium plaque was used in Australia for treatment, in particular by the dermatologists. By 1920s radiology was an established specialty. A series of conferences was held between 1930 and 1940 to discuss the provision of cancer treatment, the integration of research and particularly, the establishment of central registry. The author also paid tribute to a a series of scientific personalities for their contribution to the Australian radiation oncology. 22 refs., ills

  4. Environmental and social impact of uranium mining in Australia

    International Nuclear Information System (INIS)

    The mining of uranium at the Ranger and Jabiluka mines in Australia's Northern Territory has been assessed as a case study for the environmental and social impact of uranium mining in Australia. The level of environmental protection achieved has been very high. However, a number of social indicators reveal that the social impact of development in the region, including the mining of uranium, has been significant. A program is now underway to redress these social issues. Links between social and environmental impact have been identified. In today's world, the standards and practices in environmental protection are as much determined by social attitudes as they are by scientific and technical assessment. (author)

  5. Towards a comprehensive uranium fuel management policy for Australia

    International Nuclear Information System (INIS)

    A consideration of the problems inherent in the extraction and use of uranium fuels, in particular the long-term radiation hazard posed by wastes, leads to the recognition of several severe geological and social constraints that must govern any comprehensive management policy. In the light of these, and of the need to prevent diversion of nuclear material for the manufacture of weapons, the author outlines a comprehensive uranium fuel management policy for Australia. It is recommended that Australia's uranium should not be mined until the feasibility and cost of such a management policy have been assessed and compared with the added risks entailed in any less stringent management policy.

  9. Australia's role as an energy exporter: status and prospects

    International Nuclear Information System (INIS)

    Australia is a sparsely populated country that is well endowed with energy resources. Currently, it is the world's major coal exporter and has the potential to become - subject to political constraints - a leading uranium exporting nation. In addition, the development of the North West Shelf natural gas fields promises to provide substantial supplies for export. In contrast, Australia's indigenous production of crude oil is not expected to be sufficient to meet projected domestic demand after the mid-1980s, and the current, relatively minor, level of crude oil exports is expected to decline rapidly over the next decade.

Back in early September 2008 collective wisdom pointed to the Australian resources industry being shielded from the worst of the financial meltdown being experienced by other major economies worldwide, and all eyes were on South Australia and the Northern Territory as our uranium production centres. Fast forward six months and were are certainly feeling the pain of the global economic slowdown, and the policy banning uranium production in Western Australia (WA) has been lifted following a change of state government. Eyes are now turning west to focus on the numerous opportunities in WA.

    The present study describes the first report of Trypanosoma vegrandis in bats using morphology and sequence analysis of the 18S rRNA gene. The PCR prevalence of T. vegrandis in bats was 81.8% (18/22). The high prevalence of T. vegrandis in the present study suggests that bats may play an important role in the epidemiology of T. vegrandis in Australia. T. vegrandis appears to be geographically dispersed, has a wide distribution in Australia and low levels of host specificity. PMID:26541211

    We find that post-school education earnings premia have remained strikingly stable over the 1981 to 2003-04 period in Australia. This stability is in sharp contrast to the rising college premium observed in the US. The observed stability in Australia may in part be due to changes in the credentials earned by individuals entering certain professional occupations during the 1980s and early 1990s, particularly for females. We provide an estimate of the potential effect of within-occupation crede...

  13. An Adoption Diffusion Model of RFID-Based Livestock Management System in Australia

    Science.gov (United States)

    Hossain, Mohammad Alamgir; Quaddus, Mohammed

    Many countries, like Australia, have introduced a radio frequency identifi cation (RFID) based livestock identification and management system,which can be used for condition monitoring and fault prognosis during an outbreak situation. This paper examines the adoption process and its subsequent diffusion and extended usage of RFID in Australian livestock management practices, and proposes a research model. The model is primarily built on Rogers' innovation-diffusion theory and Oliver's expectation-confirmation theory, with some logical modifications. It posits that while adoption of RFID may be the result of legislative pressure, its further diffusion is an evaluative process, which is judged against "satisfaction" and "performance" derived from RFID systems. The implications of these and other related concepts are also discussed. Hypotheses are developed which can be tested via empirical study. The proposed model has both theoretical and practical implications. Although it is developed on the basis of the Australian livestock industry, it can be used in other countries and also in other applications with some industry-specific modifications.

    Bastrakova, I.; Fyfe, S.

    2013-12-01

    Ten years of technological innovation now enable vast amounts of data to be collected, managed, processed and shared. At the same time, organisations have witnessed government legislative and policy requirements for open access to public sector data, and a demand for flexibility in access to data by both machine-to-machine and human consumption. Geoscience Australia (GA) has adopted Data Stewardship as an organisation-wide initiative to improve the way we manage and share our data. The benefits to GA including: - Consolidated understanding of GA's data assets and their value to the Agency; - Recognition of the significant role of data custodianship and data management; - Well-defined governance, policies, standards, practices and accountabilities that promote the accessibility, quality and interoperability of GA's data; - Integration of disparate data sets into cohesive information products available online in real time and equally accessible to researchers, government, industry and the public. Although the theory behind data stewardship is well-defined and accepted and the benefits are generally well-understood, practical implementation requires an organisation to prepare for a long-term commitment of resources, both financial and human. Fundamentally this involves: 1. Raising awareness in the organisation of the need for data stewardship and the challenges this entails; 2. Establishing a data stewardship framework including a data governance office to set policy and drive organisational change; and 3. Embedding the functions and a culture of data stewardship into business as usual operations. GA holds a vast amount of data ranging from petabytes of Big Data to significant quantities of relatively small ';long tail' geoscientific observations and measurements. Over the past four years, GA has undertaken strategic activities that prepare us for Data Stewardship: - Organisation-wide audits of GA's data holdings and identification of custodians for each dataset

    2016-03-01

    Full Text Available This paper explores the implications of the militarisation of Australian history and the dilemmas of increasing public support for same-sex marriage in Australia at a time of renewed assaults on Indigenous rights, austerity measures and the silencing of dissent. The paper analyses the celebratory rhetoric which increasingly typifies both marriage equality campaigns and the commemoration of Australia’s First World War or ‘Anzac’ history in popular media and public debate. Against the confluence between ongoing debates on same-sex marriage and the ‘Anzac myth’, I highlight four key challenges: the silencing of dissent; forgetting of the Frontier Wars; untold stories of civil society achievements; and the normalising of same-sex rights. I argue that professed support for a liberal version of ‘gay rights’ exemplified by same-sex marriage, set against a militarized version of Australian history, glosses over past and ongoing injustices. A militarized version of history underpins a nationalism that misrepresents credit for advances in rights recognition, sidelining public representations of Indigenous sovereignties and the contributions of civil society, protest and social justice campaigning to the recognition and maintenance of civil and political rights. As a result, the transformative claims of Land Rights and Treaty, critiques of war, and queer politics, are contained.

    This paper aims to provide an overview of drug and alcohol issues and their management in Australia. Overall, Australia has good health relative to the United States and other similar nations and generally similar rates of substance use disorders. A whole-of-government strategic approach has been developed for managing drug and alcohol problems, with a National Drug Strategy that has adopted a pragmatic approach to substance use problems through 3 "pillars"--demand, supply, and harm reduction. This approach has been attributed to Australia's remarkably low human immunodeficiency virus (HIV) prevalence among people who inject drugs (Australian Aboriginals and Torres Strait Islanders, remains challenging primarily due to the transgenerational impacts of dispossession, social and economic disadvantage, and some cultural differences. Although substance use is a key issue for Australian Aboriginals, there are currently insufficient dedicated drug and alcohol services for this group. Notwithstanding this important exception, Australia's health and substance use is favorable relative to other developed nations, offering universal health care and a pragmatic drug and alcohol strategy.

    1990-01-01

    Demand for non-alcoholic beverages (NAB) in Australia is analyzed for the period 1964-89, with the use of consumption theory. The study's findings, which generally support those of earlier studies, suggest that demand for NAB is price-inelastic. A comparison of income elasticities further suggest that tea is an inferior good, coffee a necessity, and softdrinks, a luxury.

  2. Modelling the Balassa-Samuelson Effect in Australia

    Directory of Open Access Journals (Sweden)

    Khorshed Chowdhury

    2011-03-01

    Full Text Available This paper examines the Balassa-Samuelson hypothesis in Australia using the ARDL cointegrationframework. Evidence was found of a significant long-run relationship between real exchange rate andAustralia-US productivity differential during the period of 1950-2003. The results indicate that a one per centincrease in labour productivity in Australia relative to the US will lead to 5.6 per cent appreciation in the realexchange rate of Australia. The estimated coefficient for the error correction term is -0.1983 and is highlysignificant, indicating that the deviation from the long term real exchange rate equilibrium path is correctedby nearly 20 per cent over the following year. The Author suspects that the elasticity coefficient is “overestimated”due to the exclusion of relevant explanatory variables in the analytical model. The real exchangerate movements are affected by real fundamentals and policy-induced shifts in its real fundamentals. Thefundamentals include the terms of trade, government expenditure, real interest rate differentials, net foreignliabilities among others along with labour productivity differential.

  3. Overcoming barriers to wind project finance in Australia

    International Nuclear Information System (INIS)

    The wind power industry in Australia is expected to grow rapidly over the next decade, primarily due to a forthcoming expanded national renewable energy target (RET) which will mandate that renewable sources provide approximately 20% of Australia's electricity production by 2020. However, development of new wind generation in Australia has stalled as a result of several barriers to project finance, the mechanism through which most wind farms have been developed historically. This paper provides an overview of wind power financing in Australia in light of recent political and financial trends. Drawing upon existing literature and a series of stakeholder interviews, it identifies three primary barriers to project finance: regulatory risk surrounding legislation of the RET, semi-privatization of electricity retailers in New South Wales, and limited capital availability resulting from the recent global credit crisis. The paper concludes that the confluence of these barriers limits the availability of long-term contracts that provide revenue certainty for pre-construction wind projects, while simultaneously making these contracts a necessity in order to obtain project finance. In an attempt to mitigate these effects, this paper identifies four alternative development strategies that can be pursued.

  6. Deliberate introduction of the European rabbit, Oryctolagus cuniculus, into Australia.

    2010-04-01

    The European rabbit was brought to Australia as a companion animal by early settlers. It sometimes escaped, but failed to survive in the Australian bush. In 1879 wild rabbits were deliberately sent to Victoria to provide game for wealthy settlers to shoot. They soon spread all over Australia, except in the tropics, and became Australia's major animal pest. After careful testing in Australian wildlife and in humans, control by myxoma virus was introduced at various sites between 1937 and 1950, spreading all over the Murray-Darling Basin in 1950. Within one year mutations in the virus had led to slightly less virulence, and these continued for the next 50 years. In the early 21st Century testing viruses obtained from wild rabbits showed that the majority of these viruses were more virulent than the virus used to initiate the epidemic. In 1995 another virus specific for European rabbits, rabbit haemorrhagic disease virus, escaped from areas in which field trials were being carried out and spread around Australia. It was more successful than myxomatosis for rabbit control in arid regions. PMID:20617651

  10. Renewable energy systems for remote areas in Australia

    Energy Technology Data Exchange (ETDEWEB)

    Lowe, D.; Lloyd, C.R. [Centre for Appropriate Technology, Alice Springs (Australia)

    2001-03-01

    It has been long thought that the northern and central regions of Australia are ideal places for the installation of remote area power supplies (RAPS) based on renewable energy. In particular the solar regime in these areas is among the highest in the world. The Centre of Appropriate Technology has been undertaking a project, as part of the Australian Cooperative Research Centre for Renewable Energy research program, to look at the viability of renewable energy systems in remote areas of northern and central Australia. The study has involved compiling a database of existing knowledge of renewables in these areas combined with a set of site visits and case studies to look at both community attitudes to renewable energy and the actual operation of the systems. The study started in early 1997 and is due to be completed towards the end of 1999. The present paper outlines the logistics of the study and some of the results. The emphasis so far has been on wind and solar systems (including hybrid diesel systems) in Aboriginal communities. Some work has progressed for systems in pastoral properties and tourist ventures. The fieldwork to date has covered northern South Australia and the Northern Territory. Further fieldwork will occur in northern Queensland and Western Australia in mid 1999. (author)
