Hypersaline environments have been significant reservoirs for the long-term evolution of specifically adapted microorganisms. Characterized to have higher salt concentrations (up to 35 g/L), they are worldwide distributed and have a commercial significance. Exportadora de Sal, Guerrero Negro, Mexico has a multipond salterns system designed to harvest common salt (NaCl) from sea water. To achieve this purpose, sea water is pumped through a set of shallow ponds where water evaporates and salts concentrate. Sequential precipitation of CaCO3, CaSO4 2H2O and NaCl occurs in a mineral formations call it evaporites. In the interior of those gypsum-encrusted and halite-encrusted minerals, communities of extremely salt-loving archaea prosper. Previous studies have showed the influence of Haloarchaeal cells in the formation of larger fluid inclusions than crystals formed in sterile salt solutions. S-layer envelopes and cells of Haloarcula strain SP8807 contributed to the nucleation of new crystals of NaCl. Given the significance of the scope in phylogenetic archaeal diversity research, this study had a polyphasic approach. SEM micrographs from a 21- 31% (w/v) gradient salt multipond system evaporites, gave an insight profile of the extreme halophilic archaeal communities thriving in the surface of the gypsum and halite evaporites. Halite crystals were form after 21 days of incubation in solid medium with archaeal cells. Both culture and non-culture dependent methods, Nested-PCR-DGGE analysis and sequencing of 16S rDNA amplified fragment genes from environmental samples and isolated strains were used for this purpose. We isolate three strains from Pond 9 (21.07% total salt concentration) and one strain from Cristallizer 20 (25.15% total salt concentration). 16S rDNA signaling gave 99% of similarity with Halogeometricum borinquense, sequence AF002984, two other strains were 99% of similarity with Halobacterium salinarum, sequence AJ496185 these strains shown different colony

The use of crystal methamphetamine (ice) and the associated harms for individuals, families, and communities across Australia has been the subject of growing concern in recent years. The provision of easily accessible, evidence-based, and up-to-date information and resources about crystal methamphetamine for the community is a critical component of an effective public health response. This paper aims to describe the codevelopment process of the Web-based Cracks in the Ice Community Toolkit, which was developed to improve access to evidence-based information and resources about crystal methamphetamine for the Australian community. Development of the Cracks in the Ice Community Toolkit was conducted in collaboration with community members across Australia and with experts working in the addiction field. The iterative process involved the following: (1) consultation with end users, including community members, crystal methamphetamine users, families and friends of someone using crystal methamphetamine, health professionals, and teachers (n=451) via a cross-sectional Web-based survey to understand information needs; (2) content and Web development; and (3) user testing of a beta version of the Web-based toolkit among end users (n=41) and experts (n=10) to evaluate the toolkit's acceptability, relevance, and appeal. Initial end user consultation indicated that the most commonly endorsed reasons for visiting a website about crystal methamphetamine were "to get information for myself" (185/451, 41.0%) and "to find out how to help a friend or a family member" (136/451, 30.2%). Community consultation also revealed the need for simple information about crystal methamphetamine, including what it is, its effects, and when and where to seek help or support. Feedback on a beta version of the toolkit was positive in terms of content, readability, layout, look, and feel. Commonly identified areas for improvement related to increasing the level of engagement and personal connection

During solar salt production, large quantities of bittern, a liquid by-product containing high inorganic substance concentrations, are produced. The purpose of this research was to examine the utilization of waste bittern generated from salterns as a source for Mg production and as an absorbent for carbon dioxide (CO 2 ) capture. The study was conducted in a sequential two-step process. At NaOH/Mg molar ratios of 2.70-2.75 and pH 9.5-10.0, > 99% Mg precipitation from the bittern was achieved. After washing with water, 100-120 g/L of precipitate containing 94% Mg(OH) 2 was recovered from the bittern. At the optimum NH 4 OH concentration of 5%, 120 g of sodium bicarbonate precipitate per liter of bittern were recovered, which was equivalent to 63 g CO 2 captured per liter of bittern. These results can be used to support the use of bittern as a resource and reduce economic losses during solar salt production.

Halophilic archaea, thriving in hypersaline environments, synthesize antimicrobial substances with an unknown role, called halocins. It has been suggested that halocin production gives transient competitive advantages to the producer strains and represents one of the environmental factors influencing the microbial community composition. Herein, we report on the antibacterial activity of a new haloarchaeon selected from solar salterns of the northern coast of Algeria. A total of 81 halophilic strains, isolated from the microbial consortia, were screened for the production of antimicrobial compounds by interspecies competition test and against a collection of commercial haloarchaea. On the basis of the partial 16S rRNA sequencing, the most efficient halocin producer was recognized as belonging to Haloferax (Hfx) sp., while the best indicator microorganism, showing high sensitivity toward halocin, was related to Haloarcula genus. The main morphological, physiological and biochemical properties of Hfx were investigated and a partial purification of the produced halocin was allowed to identify it as a surface membrane protein with a molecular mass between 30 and 40 kDa. Therefore, in this study, we isolated a new strain belonging to Haloferax genus and producing a promising antimicrobial compound useful for applications in health and food industries.

The purpose of the workshop was to: identify the future needs and opportunities for single-crystal neutron diffraction, and specify instrument requirements. important number of experiments. The conclusion of the workshop deliberation was that Australia has a diverse community of users of single-crystal neutron diffraction. A (quasi)-Laue image-plate diffractometer allows the fastest throughput by far, but would exclude an important number of experiments. Most of these could be covered by the additional possibility to locate the image-plate detector on a monochromatic beam. Therefore it was recommend both a white thermal beam and a monochromatic beam (λ= 1 to 2.4 Angstroms) for an image-plate detector. At little additional cost the existing 2TanA instrument could be located semi-permanently on the same monochromatic beam, thus offering three quite different types of single-crystal instruments. Small improvements could be made to the 2TanA instrument to cater for the remaining experiments not suited to an image-plate diffractometer: exchange of the Eulerian cradle for an automated tilt goniometer for extremely bulky sample environment (cryomagnets, large pressure cells), optional larger area detector, analyser crystal. It was recommended that an Instrument Advisory Team will be assembled, and will help in specifying, designing and commissioning the instrument

The putative adhesion domain of the multidomain protein Epf from S. pyogenes has been crystallized in space groups P2 1 and P2 1 2 1 2 1 . The crystals diffracted to 2.0 and 1.6 Å resolution, respectively, at the Australian Synchrotron. The extracellular protein Epf from Streptococcus pyogenes is important for streptococcal adhesion to human epithelial cells. However, Epf has no sequence identity to any protein of known structure or function. Thus, several predicted domains of the 205 kDa protein Epf were cloned separately and expressed in Escherichia coli. The N-terminal domain of Epf was crystallized in space groups P2 1 and P2 1 2 1 2 1 in the presence of the protease chymotrypsin. Mass spectrometry showed that the species crystallized corresponded to a fragment comprising residues 52–357 of Epf. Complete data sets were collected to 2.0 and 1.6 Å resolution, respectively, at the Australian Synchrotron

A novel pink-pigmented bacterial strain, UAH-SP71T, was isolated from a saltern located in Santa Pola, Alicante (Spain) and the complete genome sequence was analysed and compared with that of Spiribacter salinus M19-40T, suggesting that the two strains constituted two separate species, with a 77.3% ANI value. In this paper, strain UAH-SP71T was investigated in a taxonomic study using a polyphasic approach. Strain UAH-SP71T was a Gram-stain-negative, strictly aerobic, non-motile curved rod that grew in media containing 5-20% (w/v) NaCl (optimum 10% NaCl), at 5-40 °C (optimum 37 °C) and at pH 5-10 (optimum pH 8). Phylogenetic analysis based on the comparison of 16S rRNA gene sequences revealed thatstrain UAH-SP71T is a member of the genus Spiribacter, showing a sequence similarity of 96.5% with Spiribacter salinus M19-40T. Other related species are also members of the family Ectothiorhodospiraceae, including Arhodomonas recens RS91T (95.5% 16S rRNA gene sequence similarity), Arhodomonas aquaeolei ATCC 49307T (95.4 %) and Alkalilimnicola ehrlichii MLHE-1T (94.9 %). DNA-DNA hybridization between strain UAH-SP71T and Spiribacter salinus M19-40T was 39 %. The major cellular fatty acids of strain UAH-SP71T were C18 : 1ω6c and/or C18 : 1ω7c, C16 : 0, C16 : 1ω6c and/or C16 : 1ω7c, C10 : 0 3-OH and C12 : 0, a pattern similar to that of Spiribacter salinus M19-40T. Phylogenetic, phenotypic and genotypic differences between strain UAH-SP71T and Spiribacter salinus M19-40T indicate that strainUAH-SP71T represents a novel species of the genus Spiribacter, for which the name Spiribacter curvatus sp. nov. is proposed. The type strain is UAH-SP71T (5CECT8396T5DSM 28542T).

Four pink-pigmented, non-motile, Gram-staining-negative and moderately halophilic curved rods, designated strains SSL50T, SSL25, SSL97 and SSL4, were isolated from a saltern located in Isla Cristina, Huelva, south-west Spain. Phylogenetic analyses based on 16S rRNA gene sequences showed that they were members of the genus Spiribacter, most closely related to Spiribacter curvatus UAH-SP71T (99.3-99.5 % sequence similarity) and Spiribacter salinus M19-40T (96.5-96.7 %). Other related strains were Alkalilimnicola ehrlichii MLHE-1T (95.1-95.3 %), Arhodomonas recens RS91T (95.1-95.2 %) and Arhodomonas aquaeolei ATCC 49307T (95.0-95.1 %), all members of the family Ectothiorhodospiraceae. The major fatty acids were C18 : 1ω6c and/or C18 : 1ω7c, C16 : 0 and C12 : 0. The DNA G+C range was 64.0-66.3 mol%. The DNA-DNA hybridization values between strains SSL50T, SSL25, SSL97, SSL4 and S. piribacter. curvatus UAH-SP71T were 37-49 %. The average nucleotide identity (ANIb) values between the genome of strain SSL50T and those of the two other representatives of the genus Spiribacter, S. curvatus UAH-SP71T and S. salinus M19-40T, were 82.4 % and 79.1 %, respectively, supporting the proposal of a novel species of the genus Spiribacter. On the basis of the polyphasic analysis, the four new isolates are considered to represent a novel species of the genus Spiribacter, for which the name Spiribacter roseus sp. nov. is proposed. The type strain is SSL50T (=CECT 9117T=IBRC-M 11076T).

The expression, purification, crystallization and diffraction of the acyl-CoA thioesterase TesB from Y. pestis are reported. X-ray crystallographic diffraction data to 2.0 Å resolution were collected at the Australian Synchrotron. Yersinia pestis is a highly virulent human pathogen and is the causative agent of bubonic plague. Spread through the bite of infected fleas, plague epidemics have marked important events in history, including the Justinian plague (6th century), the Black Death (14th century) which decimated nearly one quarter of the European population, and more recently the Orientalis plague (1894). To date, deaths are still being reported and, without treatment, the disease kills most people within 4 days. One of the thioesterases from Y. pestis, TesB, is a broad-range acyl-CoA thioesterase and is highly conserved within prokaryotes and throughout evolution, sharing sequence similarity with the HIV Nef binding protein ACOT8. Here the expression, purification, crystallization and diffraction of TesB are reported. TesB has been recombinantly expressed and crystallized using the vapour-diffusion hanging-drop technique at pH 7.0 and 290 K. After optimization, crystals diffracted to 2.0 Å resolution at the Australian Synchrotron and belong to the space group P12 1 1 (a = 73.55, b = 170.82, c = 101.98 Å), with eight molecules likely to be present in the asymmetric unit

An extremely halophilic archaeal strain SP28 T was isolated from the Gomso solar saltern, Republic of Korea. Cells of the new strain SP28 T were pleomorphic and Gram stain negative, and produced red-pigmented colonies. These grew in medium with 2.5-4.5 M NaCl (optimum 3.1 M) and 0.05-0.5 M MgCl2 (optimum 0.1 M), at 25-50 °C (optimum 37 °C) and at a pH of 6.5-8.5 (optimum pH 8.0). Mg 2+ was required for growth. A concentration of at least 2 M NaCl was required to prevent cell lysis. Polar lipids included phosphatidylglycerol, phosphatidylglycerol phosphate methyl ester, phosphatidylglycerol sulfate and one glycolipid chromatographically identical to sulfated mannosyl glucosyl diether. 16S rRNA and rpoB' gene sequence analyses showed that strain SP28 T is closely related to Haloplanus ruber R35 T (97.3 and 94.1 %, 16S rRNA and rpoB' gene sequence similarity, respectively), Haloplanus litoreus GX21 T (97.0 and 92.1 %), Haloplanus salinus YGH66 T (96.0 and 91.9 %), Haloplanus vescus RO5-8 T (95.9 and 90.9 %), Haloplanus aerogenes TBN37 T (95.6 and 90.3 %) and Haloplanus natans RE-101 T (95.3 and 89.8 %). The DNA G+C content of the novel strain SP28 T was 66.2 mol%, which is slightly higher than that of Hpn.litoreus GX21 T (65.8 mol%) and Hpn.ruber R35 T (66.0 mol%). DNA-DNA hybridization values betweenHpn.ruber R35 T and strain SP28 T and between Hpn.litoreus GX21 T and strain SP28 T were about 24.8 and 20.7 %, respectively. We conclude that strain SP28 T represents a novel species of the genus Haloplanus and propose the name Haloplanus salinarum sp. nov. The type strain is SP28 T (=JCM 31424 T =KCCM 43210 T ).

Reproductive traits of Paracartia grani [percentage of spawning females, egg production rate (EPR), and hatching success (HS)] were investigated for the first time at high salinities (39-121 psu) to examine the impact of such a particular situation. The study was done in two hypersaline ponds [A1 (39-46 psu) and C31 (70-121 psu)] in Sfax Solar Saltern, central-eastern coast of Tunisia. These ponds also differed in terms of the composition and concentrations of nutritional parameters. The EPR differed significantly between the ponds (ANOVA, F = 29.45, p eggs female- 1 day- 1 (7 December 2009) and 14 ± 1 eggs female- 1 day- 1 (19 January 2010) with an average of 13.3 ± 0.44 eggs female- 1 day- 1. HS after 48 h of incubation were significantly higher than those after 24 h. The mean values of HS after 48 h were 42.72 ± 2.58% at pond A1 and 41.67 ± 3.92% at pond C31. The two peaks of HS (after 48 h) were observed at 15 °C in pond A1 (21 December 2009, 45.18% nauplii eggs- 1) and in C31 (4 January 2010, 48.78%) at the same temperature. This study confirms that a broad salinity tolerance allows P. grani to settle itself in environments, which are normally hostile to the development of other Acartiidae.

Full Text Available Abstract Background Mature saturated brine (crystallizers communities are largely dominated (>80% of cells by the square halophilic archaeon "Haloquadratum walsbyi". The recent cultivation of the strain HBSQ001 and thesequencing of its genome allows comparison with the metagenome of this taxonomically simplified environment. Similar studies carried out in other extreme environments have revealed very little diversity in gene content among the cell lineages present. Results The metagenome of the microbial community of a crystallizer pond has been analyzed by end sequencing a 2000 clone fosmid library and comparing the sequences obtained with the genome sequence of "Haloquadratum walsbyi". The genome of the sequenced strain was retrieved nearly complete within this environmental DNA library. However, many ORF's that could be ascribed to the "Haloquadratum" metapopulation by common genome characteristics or scaffolding to the strain genome were not present in the specific sequenced isolate. Particularly, three regions of the sequenced genome were associated with multiple rearrangements and the presence of different genes from the metapopulation. Many transposition and phage related genes were found within this pool which, together with the associated atypical GC content in these areas, supports lateral gene transfer mediated by these elements as the most probable genetic cause of this variability. Additionally, these sequences were highly enriched in putative regulatory and signal transduction functions. Conclusion These results point to a large pan-genome (total gene repertoire of the genus/species even in this highly specialized extremophile and at a single geographic location. The extensive gene repertoire is what might be expected of a population that exploits a diverse nutrient pool, resulting from the degradation of biomass produced at lower salinities.

Full text: The Australian Synchrotron Research Program (ASRP) was established in 1996 under a 5 year grant from the Australian Government, and is managed by ANSTO on behalf of a consortium of Australian universities and research organisations. It has taken over the operation of the Australian National Beamline Facility (ANBF) at the Photon Factory, and has joined two CATS at the Advanced Photon Source: the Synchrotron Radiation Instrumentation CAT (SRI-CAT) and the Consortium for Advanced Radiation Sources (CARS). The ASRP thus manages a comprehensive range of synchrotron radiation research facilities for Australian science. The ANBF is a general purpose hard X-ray beamline which has been in operation at the Photon Factory since 1993. It currently caters for about 35 Australian research teams per year. The facilities available at the ANBF will be presented and the research program will be summarised. The ASRP facilities at the APS comprise the 5 sectors operated by SRI-CAT, BioCARS and ChemMatCARS. A brief description will be given of the ASRP research programs at the APS, which will considerably broaden the scope of Australian synchrotron science

β-Aminopeptidases are a unique group of enzymes that have the unusual capability to hydrolyze N-terminal β-amino acids from synthetic β-peptides. β-Peptides can form secondary structures mimicking α-peptide-like structures that are resistant to degradation by most known proteases and peptidases. These characteristics of β-peptides give them great potential as peptidomimetics. Here, the X-ray crystal structure of BcA5-BapA, a β-aminopeptidase from a Gram-negative Burkholderia sp. that was isolated from activated sludge from a wastewater-treatment plant in Australia, is reported. The crystal structure of BcA5-BapA was determined to a resolution of 2.0 Å and showed a tetrameric assembly typical of the β-aminopeptidases. Each monomer consists of an α-subunit (residues 1-238) and a β-subunit (residues 239-367). Comparison of the structure of BcA5-BapA with those of other known β-aminopeptidases shows a highly conserved structure and suggests a similar proteolytic mechanism of action.

The microbial activity had a substantial effect on the carbonate system parameters. Dissolved inorganic carbon (DIC) was substantially removed from the brine during the course of evaporation from the seawater to the point where calcium carbonate precipitates, with an accompanying decrease in its carbon isotopic composition (δ13CDIC) to as low as -10.6‰. Although the removal of DIC was due to calcium carbonate precipitation, photosynthesis, and the degassing of CO2(aq) induced by evaporation, the presence of 13C-depleted δ13CDIC in ponds where calcium carbonate precipitates can be attributed to the dissolution of atmospheric CO2 because of intensive CO2(aq) uptake by photosynthesis, and/or mineralization of organic matter by sulfate reduction. In contrast, δ13CDIC increased up to 7.2‰ in the salinity range where halite precipitates, which can be ascribed to the domination of the effect of degassing of CO2(aq) under conditions with reduced microbial activity. A gradual decrease in microbial activity was also reflected in compound-specific δ13C of photosynthetic pigments; isotopic fractionation associated with DIC assimilation increased linearly as the evaporation proceeded, indicating DIC-limited conditions within the microbial mats and gypsum crusts because of restricted DIC diffusion from the overlying brine and/or suppression of primary production at higher salinity.

We study European options on the ratio of the stock price to its average and viceversa. Some of these options are traded in the Australian Stock Exchange since 1992, thus we call them Australian Asian options. For geometric averages, we obtain closed-form expressions for option prices. For arithmetic means, we use different approximations that produce very similar results.

Washability of Australian coals

Energy Technology Data Exchange (ETDEWEB)

Whitmore, R L

1979-06-01

Australian coals tend to be young in geological age and high in ash by world standards; preparation of the coal before marketing is almost universal. On the basis of float and sink data from 39 locations in the eastern Australian coalfields, the coals are place in four categories representing increasing difficulty in their washability characteristics. These seem to be related neither to the geological age nor the geographical position of the deposit and Hunter Valley coals, for example, span all categories. The influence of crushing on the washability of Australian coals is briefly considered and from limited data it is concluded to be appreciably smaller than for British or North American coals. A strategy for the float and sink analysis of Australian coals is proposed and the influence of washability characteristics on current trends in the selection of separating processes for coking and steaming products is discussed.

Full Text Available The globalisation and consolidation of book publishing is widely seen as having negative consequences for Australian literature. Some commentators argue that this shift is detrimental to Australian literature as a whole; others identify the growth of multinational publishing conglomerates with a specific decline in Australian literary fiction. This article explores both positions, first identifying and investigating trends in Australian novel publication and comparing these to trends in the publication of novels from other countries as well as other Australian-originated literature (specifically, poetry and auto/biography. It then considers the specific case of Australian literary fiction, before looking in detail at the output of large publishers of Australian novels. This analysis reveals a recent decline in Australian novel and poetry titles, but offers a more complex picture of this trend than dominant expressions of nostalgia and alarm about the fate of Australian literature and publishing would suggest.

Sporting Chance: Indigenous Participation in Australian Sport History

Directory of Open Access Journals (Sweden)

Sean Gorman

2010-08-01

Full Text Available For many non-Indigenous Australians the only time they have any engagement with Indigenous peoples, history or issues is through watching sport on television or being at a football match at the MCG. This general myopia and indifference by settler Australians with Indigenous Australians manifests itself in many ways but perhaps most obscenely in the simple fact that Indigenous Australians die nearly 20 years younger than the rest of Australias citizens. Many non-Indigenous Australians do not know this. Sport in many ways has offered Indigenous Australians a platform from which to begin the slow, hard process for social justice and equity to be actualised. This paper will discuss the participation of Indigenous Australians in sport and show how sport has enabled Indigenous Australians to create a space so that they can speak out against the injustices they have experienced and to further improve on relations going into the future. The central contention is that through sport all Australians can begin a process of engaging with Indigenous history as a means to improve race relations between the two groups.

The mechanism of borax crystallization using in situ optical microscopy and AFM

International Nuclear Information System (INIS)

Suharso, G.; Parkinson, M.; Ogden, M.

2002-01-01

Full text: The quality of high-purity borax depends both on the concentrations of the impurities and the product appearance, which are mainly determined by the size and morphology of the crystals. Thus, knowledge about crystallization of borax is of direct relevance to the industrial production of borax. In addition, fundamental studies of borax crystallization will provide results of relevance to the crystallization of other economically important materials. An investigation into the fundamental mechanism of crystal growth of borax from aqueous solution was carried out, as a model system. The investigation focussed on the growth mechanism, and the influence of factors such as solution supersaturation, temperature, crystal size and solution flow on the rate of crystal growth. In situ optical microscopy was used to determine growth rates of three different faces of borax crystals at 20, 25, 30, and 35 deg C, at various concentrations. It was found that the growth rate increases with increasing temperature and supersaturation. At low concentration , growth on the (010), (001), and (111) faces occurs via a spiral growth mechanism and at high concentration birth and spread is the principal mechanism operating. The activation energy for the different mechanisms was determined. Examination by ex situ Atomic Force Microscopy (AFM) showed features suggesting that the (100), (010), (001) faces of borax crystals grow by spiral mechanism at low concentration and two dimensional nucleation at high concentration. These experiments support the data obtained from in situ optical microscopy. Copyright (2002) Australian Society for Electron Microscopy Inc

Linke, Christian; Siemens, Nikolai; Middleditch, Martin J; Kreikemeyer, Bernd; Baker, Edward N

2012-07-01

The extracellular protein Epf from Streptococcus pyogenes is important for streptococcal adhesion to human epithelial cells. However, Epf has no sequence identity to any protein of known structure or function. Thus, several predicted domains of the 205 kDa protein Epf were cloned separately and expressed in Escherichia coli. The N-terminal domain of Epf was crystallized in space groups P2(1) and P2(1)2(1)2(1) in the presence of the protease chymotrypsin. Mass spectrometry showed that the species crystallized corresponded to a fragment comprising residues 52-357 of Epf. Complete data sets were collected to 2.0 and 1.6 Å resolution, respectively, at the Australian Synchrotron.

Slovenia as a locale in contemporary Australian verse

Directory of Open Access Journals (Sweden)

Igor Maver

1997-12-01

Full Text Available Despite the fact that the writer Patrick White had worked on his novels for a short while also at Lake Bled in Slovenia at Hotel "Toplice", just like Agatha Christie did at Lake Bohinj, Slovenia has only recently come to feature in mainstream Australian literature, more precisely in contemporary Australian poetry. It should be stressed that Slovenia is thus no longer present only in Slovene migrant poetry written in Australia as has so far been the case: it entered the major contemporary Australian anthologies. This testifies to the fact that Slovenia no longer belongs to the uncharted part of Central Europe on the geographical and consequently also on the Australian literary map. Rather than that Slovenia increasingly makes part of an average Australian 'Grand Tour' travel itinerary in Europe; it has thus become present in the Australian cultural consciousness. In this light two recent Australian poems with Slovenia as a literary locale are discussed, Andrew Taylor's "Morning in Ljubljana" I and Susan Hampton's poem "Yugoslav Story".

Australian corporations operate in an increasingly international environment. It has intuitive appeal that Australian law should regulate the conduct of directors of Australian corporations even if it occurs outside Australia.

Firstly, does Australian law governing directors’ duties in fact apply to activities of a ...

Social influences on physical activity in Anglo-Australian and Vietnamese-Australian adolescent females in a single sex school.

Science.gov (United States)

Wilson, Andrew N; Dollman, James

2009-01-01

Social support is a consistent correlate of youth physical activity (PA) but few studies have examined this in cultural sub-groups. Female adolescents (n=113; 13.9+/-0.6years) from a metropolitan single sex private school participated in this study. PA was estimated using the 3 Day Physical Activity Recall (3dPAR), and aspects of social support using a specifically designed questionnaire. Anglo-Australians (n=74), whose parents were both born in Australia, were compared with Vietnamese-Australians (n=39), whose parents were both born in Vietnam. There were non-significant trends towards higher engagement in all measures of PA among Anglo-Australians. Anglo-Australians perceived higher levels of social support to be physically active. In the whole sample and in cultural sub-groups, support by mothers was a consistent predictor of PA. Among Vietnamese-Australians, activities shared with the mother predicted moderate to vigorous PA. Interventions targeting PA among adolescent females should consider interactions of social support and cultural background.

From Desert to Dessert: Why Australian Dust Matters.

The growth of some types of phytoplankton in several parts of the world ocean, including much of the Southern Ocean, is limited by the supply of iron. Large Australian dust storms uplift, transport and abrade soils, to produce aeolian dust that is a significant source iron to the Southern Ocean. Atmospheric processes that enhance the dissolution of iron from aeolian dusts are of interest and have been studied for material from major dust producing regions like the Sahara, Gobi and Australian deserts; the reported solubility of iron from aeolian dusts ranges from <0.01% to 80%. The characteristic red soils, sands and dusts from Australia are generally believed to consist of quartz grains with a coating of fine grains and crystals of iron oxides, primarily hematite and goethite. The precise mineralogy of soil and dust grain coatings is poorly understood and it also not well known how the coatings are altered during uplift and transport to the ocean. Current models to understand the processes operating during the transport and atmospheric processing of dust include some generalisations and simplifications that are not always warranted and our work has shown the overlooked complexity of the system. Models for aeolian-iron dissolution based on Northern Hemisphere data commonly include the pollutants SOx and NOx. The modern Southern Hemisphere is less polluted and thus resembles past environmental systems. The dissolution of iron from soils of the Saharan, Gobi and Australian deserts in the presence of protons only (i.e. without SOx and NOx) occurs in two phases. The first, faster phase, representing up to 20% of total iron is via a surface-controlled mechanism. The rate determining variable is the exposed surface area of the iron oxides and not the size of the underlying quartz grain. The second, slower, phase of dissolution occurs via the transport-controlled formation of a leached layer. During the simulated aeolian abrasion of Australian soils from dust producing

BOOMERANG - the Australian light source

Boldeman, J.W.; Garrett, R.L.

1999-01-01

A proposal has been prepared for the installation in Australia of a national high performance synchrotron light facility called Boomerang. The Boomerang proposal had its origin in the establishment of the Australian Synchrotron Research Program (ASRP) which was one of the seven Major National Research Facilities announced by the Federal Government in December 1995. The ASRP provides the opportunity and funding for Australian researchers to access international synchrotron facilities, specifically two consortia at the Advanced Photon Source (APS) at the Argonne National Laboratory, USA and continued interaction with the Photon Factory at the KEK Laboratory in Japan. The ASRP was the successor to the Australian National Beamline Facility project (ANBF) which began in 1991 following the ASTEC inquiry titled 'Small Country - Big Science'. The Federal Government also provided funding for a Feasibility Study to determine the value of establishing an Australian-based synchrotron radiation facility. The Feasibility Study was completed in August 1998 and endorsed by the institutional members of the ASRP and the research community in general. The study concluded that, on the data available in Australia, there was a strong case for the installation of an Australian-based facility. The study considered several options for an Australian-based facility and recommended that these options and the data supporting the general conclusions receive further investigation. A mission was arranged to a select group of overseas laboratories to explore these questions in detail. The review team included a mix of scientific and industrial experience and also represented the interests of the ASRP and an Industrial Synchrotron Consortium based in Victoria. Based on the conclusions of the overseas mission and incorporating the advice of all international specialists in the design and use of synchrotron facilities consulted during the mission, the most cost-effective option was an extended

Australian Queer Science Fiction Fans.

Kerry, Stephen Craig

2017-10-23

Science fiction (sf) does more than provide a fleeting moment of entertainment; it has many personal and social functions. In addition to offering audiences "romantic escapism" (Gerrold, 1996, pp. 5-6), sf also enables the "postulation of an alternative reality from which to contemplate this one" (Gerrold, 1996, pp. 5-6); as such, it is especially important "for groups which have had limited stakes in the status quo" (Jenkins, 1995, p. 242). To date, no research has been undertaken on the relationship between Australian queers and sf fandom. This article reports the findings of an online survey and explores the psycho-social features of Australian queer sf fans and why they like the genre. While the characteristics of this sample mirror those of Australian queers generally, they also have slightly higher rates of mental illness and are far more likely to state they have "no religion." Furthermore, while enjoying the "sciency" (P10, bisexual woman) aspects of sf, Australian queers also like the "poignant metaphors for our own civilization" (P45, asexual man).

Australian minerals industry 1985-6

Energy Technology Data Exchange (ETDEWEB)

1987-01-01

The performance of the Australian mineral industry in 1985-86 was again adversely affected by low commodity prices and tight market conditions. This is shown in a survey conducted by chartered accountants Coopers and Lybrand and published by the Australian Mining Industry Council (AMIC). In a preface to the report, the president of AMIC (Sir Bruce Watson) said: In just 10 years the minerals industry has emerged as Australia's major exporter, accounting for over 40% of total Australian exports of goods. This preeminent ranking has depended on a significant investment effort, and in the creation of a very large asset base. Financing this investment, and achieving the cash flow necessary to service it, are enormous tasks.

Comparison and Validation of Long Time Serial Global GEOV1 and Regional Australian MODIS Fractional Vegetation Cover Products Over the Australian Continent

2015-05-01

Full Text Available Fractional vegetation cover (FVC is one of the most critical parameters in monitoring vegetation status. Comprehensive assessment of the FVC products is critical for their improvement and use in land surface models. This study investigates the performances of two major long time serial FVC products: GEOV1 and Australian MODIS. The spatial and temporal consistencies of these products were compared during the 2000–2012 period over the main biome types across the Australian continent. Their accuracies were validated by 443 FVC in-situ measurements during the 2011–2012 period. Our results show that there are strong correlations between the GEOV1 and Australian MODIS FVC products over the main Australian continent while they exhibit large differences and uncertainties in the coastal regions covered by dense forests. GEOV1 and Australian MODIS describe similar seasonal variations over the main biome types with differences in magnitude, while Australian MODIS exhibit unstable temporal variations over grasslands and shifted seasonal variations over evergreen broadleaf forests. The GEOV1 and Australian MODIS products overestimate FVC values over the biome types with high vegetation density and underestimate FVC in sparsely vegetated areas and grasslands. Overall, the GEOV1 and Australian MODIS FVC products agree with in-situ FVC values with a RMSE around 0.10 over the Australian continent.

Full text: The Australian Synchrotron Research Program (ASRP) was one of seven major national research facilities funded by the Federal Government in December 1995. The program provides guaranteed access and travel funds for Australian scientists to conduct synchrotron radiation-based research at two overseas facilities - the Photon Factory at Tsukuba in Japan and the Advanced Photon Source at the Argonne National Laboratory in the US. The Federal Government also provided funding of $100K to carry out a Feasibility Study for an Australian-based facility. This has been completed and included a mission to a number of laboratories overseas that were or had recently constructed a facility that could be considered for Australia. Following the mission, consensus was achieved within the community for the specifications of a proposed Australian facility. The proposed facility, Boomerang, has an energy of 3 GeV, an emittance of 16 nm rad and will be equipped in the first phase with 9 instrument stations. Boomerang will be competitive in performance with other facilities currently under construction overseas. A detailed proposal has been submitted to the Federal Government for funding. No site has been specified in the proposal. The proposal was prepared within the Australian Synchrotron Research Program (ASRP) following extensive consultation with industrial and scientific groups in all Australian states. Valuable contributions have been made by members of all the committees of the ASRP, the Australian synchrotron research community that works through the ASRP and the National Synchrotron Steering Committee. Important contributions have also been made by many industrial groups including consortia in Victoria, Queensland and New South Wales. The input from the ANKA staff at Forschungszentrum Karlsruhe and, in particular. Professor Einfeld has been a critical component. The estimated capital cost of a no frills laboratory has been estimated to be $100M in 1999 dollars. The

Full Text Available It is acknowledged that health outcomes for Australian Indigenous peoples are lower than those of non-Indigenous Australians. Research suggests negative media in relation to Indigenous Australians perpetuates racist stereotypes among the wider population and impacts on the health of Indigenous Australians. This study examined the media portrayal of Indigenous Australian public health issues in selected media over a twelve month period and found that, overwhelmingly, the articles were negative in their portrayal of Indigenous health. A total of 74 percent of the coverage of Australian Indigenous related articles were negative, 15 percent were positive, and 11 percent were neutral. The most common negative subject descriptors related to alcohol, child abuse, petrol sniffing, violence, suicide, deaths in custody, and crime.

Responding to Indigenous Australian Sexual Assault

Directory of Open Access Journals (Sweden)

Janya McCalman

2014-01-01

Full Text Available Indigenous Australians experience a high prevalence of sexual assault, yet a regional sexual assault service found few Indigenous Australians accessed their services. This prompted exploration of how its services might be improved. A resultant systematic search of the literature is reported in this article. Seven electronic databases and seven websites were systematically searched for peer reviewed and gray literature documenting responses to the sexual assault of Indigenous Australians. These publications were then classified by response type and study type. Twenty-three publications met the inclusion criteria. They included studies of legal justice, media, and community-based and mainstream service responses for Indigenous survivors and perpetrators. We located program descriptions, measurement, and descriptive research, but no intervention studies. There is currently insufficient evidence to confidently prescribe what works to effectively respond to Indigenous Australian sexual assault. The study revealed an urgent need for researchers, Indigenous communities, and services to work together to develop the evidence base.

Dare nuclear energy with the Australian Nuclear Association

International Nuclear Information System (INIS)

Anon.

2016-01-01

Australian authorities have been traditionally opposed to nuclear energy. The interdiction to build nuclear power plants in the Australian states without the approval of the federal authority was even officially written in the environment code in 1999. Today coal provides 75% of the electricity needs of Australia. Because of climate warming, things are changing, the Australian government is now considering the possibility of using nuclear energy and a site located in southern Australian has been selected for the disposal of low and intermediate level radioactive wastes. In this context the Australian Nuclear Association (ANA) is developing an ambitious program for the promotion of all the applications of nuclear energy through the organisation of conferences and meetings with various experts of nuclear industry. The aim is to make the public aware of the assets of nuclear energy. (A.C.)

Evidence of Australian bat lyssavirus infection in diverse Australian bat taxa.

Science.gov (United States)

Field, Hume Ernest

2018-05-21

Historically, Australia was considered free of rabies and rabieslike viruses. Thus, the identification of Australian bat lyssavirus (ABLV) in 1996 in a debilitated bat found by a member of the public precipitated both public health consternation and a revision of lyssavirus taxonomy. Subsequent observational studies sought to elaborate the occurrence and frequency of ABLV infection in Australian bats. This paper describes the taxonomic diversity of bat species showing evidence of ABLV infection to better inform public health considerations. Blood and/or brain samples were collected from two cohorts of bats (wild-caught and diagnostic submissions) from four Australian states or territories between April 1996 and October 2002. Fresh brain impression smears were tested for ABLV antigen using fluorescein-labelled anti-rabies monoclonal globulin (CENTOCOR) in a direct fluorescent antibody test; sera were tested for the presence of neutralising antibodies using a rapid fluorescent focus inhibition test. A total of 3,217 samples from 2,633 bats were collected and screened: brain samples from 1,461 wild-caught bats and 1,086 submitted bats from at least 16 genera and seven families, and blood samples from 656 wild-caught bats and 14 submitted bats from 14 genera and seven families. Evidence of ABLV infection was found in five of the six families of bats occurring in Australia, and in three of the four Australian states/territories surveyed, supporting the historic presence of the virus in Australia. While the infection prevalence in the wild-caught cohort is evidently low, the significantly higher infection prevalence in rescued bats in urban settings represents a clear and present public health significance because of the higher risk of human exposure. © 2018 Blackwell Verlag GmbH.

Heart failure among Indigenous Australians: a systematic review

Directory of Open Access Journals (Sweden)

Woods John A

2012-11-01

Full Text Available Abstract Background Cardiovascular diseases contribute substantially to the poor health and reduced life expectancy of Indigenous Australians. Heart failure is a common, disabling, progressive and costly complication of these disorders. The epidemiology of heart failure and the adequacy of relevant health service provision in Indigenous Australians are not well delineated. Methods A systematic search of the electronic databases PubMed, Embase, Web of Science, Cinahl Plus, Informit and Google Scholar was undertaken in April 2012 for peer-reviewed journal articles relevant to the topic of heart failure in Indigenous Australians. Additionally, a website search was done to identify other pertinent publications, particularly government reports. Results There was a paucity of relevant peer-reviewed research, and government reports dominated the results. Ten journal articles, 1 published conference abstract and 10 reports were eligible for inclusion. Indigenous Australians reportedly have higher morbidity and mortality from heart failure than their non-Indigenous counterparts (age-standardised prevalence ratio 1.7; age-standardised hospital separation ratio ≥3; crude per capita hospital expenditure ratio 1.58; age-adjusted mortality ratio >2. Despite the evident disproportionate burden of heart failure in Indigenous Australians, the accuracy of estimation from administrative data is limited by poor indigenous identification, inadequate case ascertainment and exclusion of younger subjects from mortality statistics. A recent journal article specifically documented a high prevalence of heart failure in Central Australian Aboriginal adults (5.3%, noting frequent undiagnosed disease. One study examined barriers to health service provision for Indigenous Australians in the context of heart failure. Conclusions Despite the shortcomings of available published data, it is clear that Indigenous Australians have an excess burden of heart failure. Emerging data

Methods Statistical analyses were performed on data from the Australian National Drug Strategy Household Survey 2010 and alcohol data collected from an online retailer to calculate the proportion, frequency, quantity and revenues from alcohol consumption by young Australians. Results One-third of adolescents (12-17 years old) and 85% of young adults (18-25 years old) consume alcohol. More than half the adolescents' alcohol consumption is from ready-to-drink spirits. Revenue generated from alcohol consumption by 12-25 year olds is estimated at $4.8 billion in 2010 (2014 Australian dollars): $2.8 billion to industry (sales) and $2.0 billion to government (taxes). Conclusions Alcohol consumption by young Australians is prevalent, and young Australian drinkers consume alcohol in substantial amounts. The industry and taxation revenue from young drinkers is also considerable. It would be in the public interest to divert some of this revenue towards health initiatives to reduce drinking by young people, especially given the high societal costs of alcohol consumption. What is known about the topic? Australian adolescents aged 12-17 years consume substantial amounts of alcohol, and substantial amounts of revenue are generated from alcohol sales to them. What does this paper add? This paper provides recent estimates of alcohol consumption and revenue generated by Australian adolescents, and extends estimates to young adults aged 18-25 years. What are the implications for practitioners? A substantial proportion of Australian young people consume alcohol. The sales and taxation revenue generated from young people's drinking is substantial at A$4.8 billion in 2010 and is higher in real terms than estimates from previous studies. Some of the alcohol taxation revenue could be diverted to health promotion and education for

Full text: Full text: Fusion, the process that powers the sun and stars, offers a solution to the world's long-term energy needs: providing large scale energy production with zero greenhouse gas emissions, short-lived radio-active waste compared to conventional nuclear fission cycles, and a virtually limitless supply of fuel. Almost three decades of fusion research has produced spectacular progress. Present-day experiments have a power gain ratio of approximately 1 (ratio of power out to power in), with a power output in the 10's of megawatts. The world's next major fusion experiment, the International Thermonuclear Experimental Reactor (ITER), will be a pre-prototype power plant. Since announcement of the ITER site in June 2005, the ITER project, has gained momentum and political support. Despite Australia's foundation role in the field of fusion science, through the pioneering work of Sir Mark Oliphant, and significant contributions to the international fusion program over the succeeding years, Australia is not involved in the ITER project. In this talk, the activities of a recently formed consortium of scientists and engineers, the Australian ITER Forum will be outlined. The Forum is drawn from five Universities, ANSTO (the Australian Nuclear Science and Technology Organisation) and AINSE (the Australian Institute for Nuclear Science and Engineering), and seeks to promote fusion energy in the Australian community and negotiate a role for Australia in the ITER project. As part of this activity, the Australian government recently funded a workshop that discussed the ways and means of engaging Australia in ITER. The workshop brought the research, industrial, government and general public communities, together with the ITER partners, and forged an opportunity for ITER engagement; with scientific, industrial, and energy security rewards for Australia. We will report on the emerging scope for Australian involvement

To investigate and report the diet quality of young Australian women by pregnancy status. Pregnancy status was defined as pregnant (n 606), trying to conceive (n 454), had a baby in the last 12 months (n 829) and other (n 5597). The Dietary Questionnaire for Epidemiological Studies was used to calculate diet quality using the Australian Recommended Food Score (ARFS) methodology. Nutrient intakes were compared with the Nutrient Reference Values for Australia and New Zealand. A population-based cohort participating in the Australian Longitudinal Study on Women's Health (ALSWH). A nationally representative sample of Australian women, aged 25 to 30 years, who completed Survey 3 of the ALSWH. The 7486 women with biologically plausible energy intake estimates, defined as >4.5 but food group accounted for this small difference. Across all pregnancy categories there were important nutrients that did not meet the current nationally recommended levels of intake, including dietary folate and fibre. Women do not appear to consume a wider variety of nutritious foods when planning to become pregnant or during pregnancy. Many young Australian women are failing to meet key nutrient targets as nationally recommended.

Full Text Available The study examines the perception of activity based costing (ABC in Australian universities. Using a questionnaire survey, data was collected from twenty-six finance directors and/or chief financial officers in Australian universities. The perception of ABC implementation in Australian universities depends on many variables including the understanding of ABC, consideration of ABC as a strategic cost management system, the role of ABC in reduction of expenses, consideration of ABC as a valuable tool to enhance overhead cost allocation, and consideration of ABC as an effective strategic cost management system designed to incorporate the university’s critical input, output, and process variables resulting in value creation. The result of regression analysis provides significant and positive association between the decision to implement ABC in Australian universities and both the treatment of ABC as a strategic cost management system and the degree of both senior management and internal champion support. The findings indicate substantial differences in the allocation of the overhead costs between ABC and traditional costing systems. The result also reveals that many Australian universities using the ABC method receive benefits in improving cost reduction and better resource allocation with revenue surplus. Furthermore, the study develops a generic model of cost pools and drivers of ABC implementation in Australian universities.

In the early years of the twentieth century, Australia's leading economists were well versed in the nature of Australian agriculture but it was not until the 1930s and 1940s that scientists and economists alike realised there was an obvious need for trained agricultural economists. In this paper it is argued that the foundations of Australian agricultural economics were laid in the period immediately following the economic upheaval of the Great Depression and the Second World War.

Full Text Available This study investigates the association between the level of compliance of Australian listed companies with Australian corporate governance principles, in aggregate, and the level of discretionary accruals using the modified Jones model. It is hypothesised that higher levels of compliance would be associated with lower levels of discretionary accruals. Data from a random sample of 214 Australian listed companies for the years 2009 and 2010 were used to test the hypothesis. The results demonstrate a significant negative relationship indicating that companies with higher levels of compliance engage in lower levels of earnings management via discretionary accruals.

Understanding Consumer Preferences for Australian Sparkling Wine vs. French Champagne

Full Text Available Sparkling wine represents a small but significant proportion of the Australian wine industry’s total production. Yet, Australia remains a significant importer of French Champagne. This study investigated consumer preferences for Australian sparkling wine vs. French Champagne and any compositional and/or sensorial bases for these preferences. A range of French and Australian sparkling wines were analyzed by MIR spectroscopy to determine if sparkling wines could be differentiated according to country of origin. A subset of wines, comprising two French Champagnes, a French sparkling wine and three Australian sparkling wines, were selected for (i descriptive analysis to characterize their sensory profiles and (ii acceptance tests to determine consumer liking (n = 95 Australian wine consumers. Significant differences were observed between liking scores; on average, the $70 French Champagne was liked least and the $12 Australian sparkling wine liked most, but segmentation (based on individual liking scores identified clusters comprising consumers with distinct wine preferences. Interestingly, when consumers were shown wine bottle labels, they considered French wines to be more expensive than Australian wines, demonstrating a clear country of origin influence.

What is at stake? Exploring the moral experience of stigma with Indian-Australians and Anglo-Australians living with depression.

Brijnath, Bianca; Antoniades, Josefine

This article applies the framework of moral experience to examine the cultural experience of stigma with Indian-Australians and Anglo-Australians living with depression in Melbourne, Australia. To date few studies have examined this dynamic in relation to mental illness and culture, and no studies have applied this framework in a culturally comparative way. Based on 58 in-depth interviews with people with depression recruited from the community, we explicate how stigma modulates what is at stake upon disclosure of depression, participants' lived experience following that disclosure, and how practices of health-seeking become stigmatised. Findings show that the social acceptance of depression jars against participants' experience of living with it. Denialism and fear of disclosure were overwhelming themes to emerge from our analysis with significant cultural differences; the Anglo-Australians disclosed their depression to family and friends and encountered significant resistance about the legitimacy of their illness. In contrast, many Indian-Australians, especially men, did not disclose their illness for fear of a damaged reputation and damaged social relations. For Indian-Australians, social relations in the community were at stake, whereas for Anglo-Australians workplace relations (but not community relations) were at stake. Participants' experiences in these settings also influenced their patterns of health-seeking behaviors and age and inter-generational relationships were important mediators of stigma and social support. These findings illuminate how stigma, culture, and setting are linked and they provide critical information necessary to identify and develop customised strategies to mitigate the harmful effects of stigma in particular cultural groups.

Enhancing User Access to Australian marine data - the Australian Ocean Data Network

Proctor, R.; Mancini, S.; Blain, P. J.

2017-12-01

The Integrated Marine Observing System (IMOS) is a national project funded by the Australian government established to deliver ocean observations to the marine and climate science community. Now in its 10th year its mission is to undertake systematic and sustained observations and to turn them into data, products and analyses that can be freely used and reused for broad societal benefits. As IMOS has matured as an observing system the expectation of the system's availability and reliability has also increased and IMOS is now seen as delivering `operational' information; it does this through the Australian Ocean Data Network (AODN). The AODN runs its services in the commercial cloud service Amazon Web Services. This has enabled the AODN to improve the system architecture, utilizing more advanced features like object storage (S3 - Simple Storage Service) and autoscaling features, and introducing new checking and logging procedures in a pipeline approach. This has improved data availability and resilience while protecting against human errors in data handling and providing a more efficient ingestion process. Many of these features are available through AODN to the wider Australian marine and science community enabling the `family' of AODN to grow, thereby enabling rapid access to an increasing collection of ocean observations.

Japanese wives in Japanese-Australian intermarriages

Directory of Open Access Journals (Sweden)

Jared Denman

2009-12-01

Full Text Available The diasporic experiences of Japanese partners married to Australians and living in Australia are largely unexamined. This article is based on a study, conducted for an honours thesis, which invited four Japanese wives living in South East Queensland to describe, together with their Australian husbands, their family’s interactions with Japan, its language and culture, and the local Japanese community. It was recognised that the extensive social networks these wives had established and maintained with local Japanese women from other Japanese-Australian intermarriage families were an important part of their migrant experience. This article will firstly review the literature on contemporary Japanese- Australian intermarriage in Australia and Japanese lifestyle migration to Australia. It will then describe and examine the involvement and motivations of the four wives in their social networks. Entry into motherhood was found to be the impetus for developing and participating in informal, autonomous networks. Additionally, regular visits to Japan were focused on engagement with existing family and friendship networks. The contemporary experience of intermarriage for these women is decidedly transnational and fundamentally different from that of the war brides, or sensō hanayome.

Metaphyseal osteopathy in three Australian Kelpie siblings.

Greenwell, C M; Brain, P H; Dunn, A L

2014-04-01

Metaphyseal osteopathy (MO) was diagnosed in three Australian Kelpie puppies that were presented for veterinary assessment of lameness. The three puppies were siblings. Each was from a different litter by the same breeding pair. The puppy in case one was seen by the authors, and the puppies in cases two and three were patients at other veterinary hospitals. However, the medical records and radiographs were examined and reviewed for this report. Radiographic investigation of the lameness revealed pathognomonic appearance of MO affecting the metaphyseal region of the long bones in all three puppies. The diagnosis was confirmed on histopathology in one patient. MO is considered a disease of large and giant-breed dogs, being rarely reported in non-large-breed dogs, and has not been reported in the Australian Kelpie, which is considered a medium-breed dog. This case series suggests a previously unreported breed predisposition to MO in the Australian Kelpie. © 2014 Australian Veterinary Association.

The blot on the landscape: Fred Williams and Australian art history

Directory of Open Access Journals (Sweden)

Keith Broadfoot

2014-12-01

Full Text Available A defining shift in Australian art historiography occurred with the publishing of Bernard Smith’s 1980 Boyer Lecture series, The Spectre of Truganini. Seeing the exclusion of an Aboriginal presence in Australian art through the ideas of Freud, the history of Australian art, Smith proposed, was a history of repression. After Smith, Ian McLean has developed the most detailed account of the history of Australian art according to this methodology. This essay examines the work of the modern Australian artist Fred Williams in relation to both Smith and McLean’s understanding of the history of Australian art but to expand on their work I argue that, rather than Freud alone, it is Lacan’s refiguring of Freud that offers us the most insight into Williams’s work. Further, insofar as I argue that the history of Australian art is the very subject matter of Williams’s work, his work stands in for a wider project, the understanding of the history of Australian art according to Lacan’s proposal of a foundational split between the eye and the gaze.

Australian Aboriginal Astronomy - An Overview

Science.gov (United States)

Norris, Ray P.; Hamacher, Duane W.

The traditional cultures of Aboriginal Australians include a significant astronomical component, perpetuated through oral tradition, ceremony, and art. This astronomical component includes a deep understanding of the motion of objects in the sky, and this knowledge was used for practical purposes such as constructing calendars. There is also evidence that traditional Aboriginal Australians made careful records and measurements of cyclical phenomena, paid careful attention to unexpected phenomena such as eclipses and meteorite impacts, and could determine the cardinal points to an accuracy of a few degrees.

Australian coal - on top down under

Energy Technology Data Exchange (ETDEWEB)

1988-04-01

Australian coal exports have risen to record levels of 102mt in 1987. Whilst the industry is characterised by impressive export tonnages and high quality product, these assets do not always indicate real returns for the coal exporter when faced with today's competitive international market. The Australian coal industry has initiated large scale cost reduction and rationalisation programmes to offset losses in revenue, accompanied by the construction of sophisticated, efficient loading facilities. The article examines some of the reasons behind continued success by exporters in the international market, before going on to consider the longer term outlook for the Australian ndustry as a whole. A historical perspective is described, tracing the development of the coal industry from early exploratory development to the highly-tuned industry of today. 2 tabs., 12 figs.

Medical radioisotope production - the Australian experience

Druce, M. [Australian Nuclear Science and Technology Organisation, Menai (Australia)

1996-12-31

The Australian government, through its instrumentality, the Australian Nuclear Science and Technology Organization (ANSTO), owns and operates a 10-MW Dido-class research reactor at Lucas Heights on the southern outskirts of Sydney. This is the only operating nuclear reactor in Australia. It was built in 1958 and has a maximum flux of 1 x 10{sup 14} n/cm{sup 2}{center_dot}s. ANSTO also jointly owns and operates a 30-MeV IBA negative ion cyclotron at Camperdown in central Sydney, which began operation in 1992. ANSTO is predominantly a research organization; however, radioisotopes are commercially produced through Australian Radioisotopes (ARI), an ANSTO business entity. Seventy-four people are employed by ARI, which is a vertically integrated organization, i.e., everything from target preparation to sale of products is undertaken.

A Community Standard: Equivalency of Healthcare in Australian Immigration Detention.

Science.gov (United States)

Essex, Ryan

2017-08-01

The Australian government has long maintained that the standard of healthcare provided in its immigration detention centres is broadly comparable with health services available within the Australian community. Drawing on the literature from prison healthcare, this article examines (1) whether the principle of equivalency is being applied in Australian immigration detention and (2) whether this standard of care is achievable given Australia's current policies. This article argues that the principle of equivalency is not being applied and that this standard of health and healthcare will remain unachievable in Australian immigration detention without significant reform. Alternate approaches to addressing the well documented issues related to health and healthcare in Australian immigration detention are discussed.

A requirement for Australian research: access to 'big science' facilities, a report by the Australian National Committee for crystallography

International Nuclear Information System (INIS)

1989-03-01

Two types of 'Big Science' research facility - synchrotron radiation sources and intense neutron beams - are now recognised as essential resources for a wide range of research activities in chemistry, physics and biology. The cost of such facilities and the lack of a sufficiently large user base will probably preclude their construction in Australia in the foreseeable future. The needs of Australian crystallographers for access to such facilities are assessed. In relation to synchrotron radiation sources, the Committee considered only the question of access to such facilities overseas. In relation to neutron beam sources, the Committee's inquiries included not only the question of access to powerful facilities overseas but also the special problems which confront Australian crystallographers as a result of the obsolescence of the HIFAR reactor. The arguments about, and options for, funding Australian use of facilities overseas are presented. The Committee concluded there is a strong case for the purchase of a beam-line at an overseas synchrotron radiation facility and a strong, though less urgent, case for substantial Australian involvement in an overseas neutron beam facility. The Committee recommended that the Australian HIFAR reactor be refurbished in its present shell, retaining the present flux and power levels, and that in the upgrading of the neutron scattering instrumentation at HIFAR special consideration be given to including items which are sufficiently specialised to attract the international neutron scattering community

Liminality, the Australian State and Asian Nurse Immigrants

Directory of Open Access Journals (Sweden)

E. M. Willis

2014-05-01

Full Text Available Over the last two decades the flow of Asians to Australia through legitimate immigration programs has accelerated. This is particularly the case for Asian nurses coming from countries that were once subjected to European colonisation. The difficulties encountered by nurses from Asian countries mirror those of earlier waves of migrants. These include navigating the language and differences in cultural mores, values, and beliefs, along with the loneliness that may come from leaving strong family ties at home. While racism has been evident for all earlier waves of migrants, Asians face an additional hurdle linked to the uneasy relationship Australians and the Australian state has with Asia. Australia is geographically in Asia, but culturally Anglo and European.  The impact this might have on the working relationships of Asian and Australian born registered nurses is significant given the nature of their work in caring for the sick and elderly. This liminal relationship between the Australian state and Asians provides a theoretical insight into the particular difficulties experienced by Asian nurses and the integration programs that might assist them and their Australian colleagues to develop cohesive working relationships.

Full text: Earlier this year, the Australian Health Ministers' Advisory Council accepted the Federal Government's offer to fund the establishment and operation for 3 years of an Australian Clinical Dosimetry Service (ACDS). The service will be located within the Australian Radiation Protection and Nuclear Safety Agency in Yallambie, Victoria and will commence operation at the beginning of 20II. The purpose of the ACDS is to make available independent checks and auditing services to all Australian radiotherapy services. These services will range form postal audits to site visits, and include treatment dose assessments using phantoms (Level III audits). There will be a Clinical Advisory Group to oversee the development of the service, so the ACPSEM and other professional groups will playa key role in developing the ACDS. In consultation with radiotherapy facilities, the ACDS will establish an Audit Panel which will be made up of local staff to assist with on site work and minimise travel costs. The results of all measurements made by the ACDS will be confi dential: only de-identified data would be publicly reported. The service will be free to participating facilities in the first 3 years. An independent review will be conducted in the third year to determine the ongoing arrangements for the service.

Preventing proliferation : the role of Australian uranium

International Nuclear Information System (INIS)

Falk, J.

1987-01-01

The uranium debate has polarised Australian society for almost a decade. From 1977 until just before it achieved office in 1983 the Australia Labor Party took a position of strong opposition to uranium exports. The Australian Council of Trade Unions, the Australian Democrats, the Nuclear Disarmament Party, and many other organisations and sections of the community continue to oppose uranium mining and exports. Australia's uranium is currently exported for use in the commercial nuclear fuel cycle. But as the nuclear plants which are part of this cycle spread across the world, the risk rises that they will provide the cover and facilities for increasing numbers of countries to move towards nuclear weapons capability

Indian Jute in Australian Collections: Forgetting and Recollecting Transnational Networks

Directory of Open Access Journals (Sweden)

Andrew Hassam

2011-12-01

Full Text Available Indian jute sacking played an essential role in Australian life for over 150 years, yet its contribution to Australian development and its Indian origins have been barely recognised in Australian public collections. What has Australian history gained by this erasing of jute from public memory? Wool, sugar and hop sacks are displayed in public collections as evidence of an Australian national story, but their national dimension depends on the cultural invisibility of jute and jute’s connections to the stories of other communities in other places. Developing an awareness of the contribution of Indian jute to the development of Australia requires an awareness not simply that jute comes from India but that the construction of national identity by collecting institutions relies on forgetting those transnational connections evident in their own collections. Where jute sacks have been preserved, it is because they are invested with memories of a collective way of life, yet in attempting to speak on behalf of the nation, the public museum denies more multidimensional models of cultural identity that are less linear and less place-based. If Indian jute is to be acknowledged as part of ‘the Australian story’, the concept of an Australian story must change and exhibitions need to explore, rather than ignore, transnational networks.

A description of 'Australian Lyme disease' epidemiology and impact: an analysis of submissions to an Australian senate inquiry.

Science.gov (United States)

Brown, Jeremy D

2018-04-01

Many Australian patients are diagnosed and treated for the scientifically and politically controversial diagnosis of an endemic form of 'Australian Lyme Disease'. Patient advocacy led Senator John Madigan to propose an Australian Senate Inquiry into this illness. To describe the symptomology and outcomes of patients diagnosed and treated with Lyme disease in Australia. All public, first-person submissions (n = 698) to the inquiry were reviewed and responses analysed for epidemiology, symptoms and impact against structured criteria. The most common symptoms described were fatigue (62.6%), disordered thinking (51.9%) and sensory disturbance (46.1%). Respondents reported experiencing symptoms for a median of 10 years and spent a median of $30 000 on diagnosis and treatment. Almost 10% of respondents self-diagnosed after being exposed to a media report of Australian Lyme disease. Patients diagnosed with Lyme disease in Australia display a symptomology similar to 'medically unexplained physical symptoms' syndromes, experience social and financial harms, and are at risk of nosocomial harms. Negative medical interactions and the media may contribute to patients seeking alternative and potentially non-evidence-based diagnoses and treatments. © 2018 Royal Australasian College of Physicians.

To evaluate published spirometry data for Australian Aboriginal and Torres Strait Islander (Indigenous) peoples to determine (i) whether their ethnicity influenced spirometry results; and (ii) if any reliable spirometry reference values exist for Indigenous Australians. Systematic review of published and grey literature. PubMed and Cochrane Library databases, references of included articles and appropriate grey literature. Last searches were conducted in April 2016. We included any study that performed spirometry on healthy Indigenous Australians and compared their results with those from people of European ancestry. Two authors independently screened titles and abstracts and then reviewed potentially relevant full-text articles for possible inclusion. We used PRISMA systematic review reporting methods to collate data. Of a possible 125 studies, 18 full-text articles were reviewed, but only nine fulfilled the inclusion criteria. None specified Torres Strait Islander inclusion. All studies reported lower spirometry values (as much as 30% lower) for Aboriginal people compared with non-Indigenous people. Five studies developed spirometry reference values for Indigenous Australians; however, none adhered to all participant inclusion and exclusion criteria outlined by the American Thoracic Society and European Respiratory Society. Hence, reported results and subsequent reference values may not be a true representation of spirometry values in healthy Indigenous people. The lower spirometry values reported for Indigenous Australians may be due to study limitations. Furthermore, there are currently no reliable spirometry reference values for Indigenous Australians that adhere to current guidelines. Developing a set of Indigenous Australian reference values will improve the accuracy of test interpretation and aid in the diagnosis of respiratory disease in this population.

Crystallization mechanisms of acicular crystals

Puel, François; Verdurand, Elodie; Taulelle, Pascal; Bebon, Christine; Colson, Didier; Klein, Jean-Paul; Veesler, Stéphane

2008-01-01

In this contribution, we present an experimental investigation of the growth of four different organic molecules produced at industrial scale with a view to understand the crystallization mechanism of acicular or needle-like crystals. For all organic crystals studied in this article, layer-by-layer growth of the lateral faces is very slow and clear, as soon as the supersaturation is high enough, there is competition between growth and surface-activated secondary nucleation. This gives rise to pseudo-twinned crystals composed of several needle individuals aligned along a crystallographic axis; this is explained by regular over- and inter-growths as in the case of twinning. And when supersaturation is even higher, nucleation is fast and random. In an industrial continuous crystallization, the rapid growth of needle-like crystals is to be avoided as it leads to fragile crystals or needles, which can be partly broken or totally detached from the parent crystals especially along structural anisotropic axis corresponding to weaker chemical bonds, thus leading to slower growing faces. When an activated mechanism is involved such as a secondary surface nucleation, it is no longer possible to obtain a steady state. Therefore, the crystal number, size and habit vary significantly with time, leading to troubles in the downstream processing operations and to modifications of the final solid-specific properties. These results provide valuable information on the unique crystallization mechanisms of acicular crystals, and show that it is important to know these threshold and critical values when running a crystallizer in order to obtain easy-to-handle crystals.

Family food choice is complex with a number of people within the family sharing food choice and preparation responsibilities. Differences in dietary behaviours also exist between various ethnic groups worldwide, and are apparent within multicultural nations such as Australia. This study examined the intergenerational transmission of eating behaviour through semi-structured family interviews with 27 three generation families (Anglo-Australian: n = 11, Chinese-Australian: n = 8, Italian-Australian: n = 8; N = 114). The influence of generation (grandparent, parent, child), role (grandmother, grandfather, mother, father, daughter, son), and ethnic background were considered. Thematic analysis identified that regardless of ethnic background, grandmothers and mothers dominated family food choice decisions even in families where fathers were primarily responsible for the preparation of family meals. The women in each generation influenced fruit and vegetable intake by controlling purchasing decisions (e.g., by shopping for food or editing family grocery shopping lists), insisting on consumption, monitoring and reminding, utilizing food as a prerequisite for conditional treats (e.g., eating fruit before being allowed snacks), instigating and enforcing food rules (e.g., fast food only on weekends), and restricting others' food choices. Grandparents and children shared a relationship that skipped the parent generation and influenced dietary behaviours bi-directionally. These findings have implications for the delivery of dietary health messages used in disease prevention interventions designed to successfully reach culturally and linguistically diverse populations and all members of multigenerational families.

Full text: The Australian Synchrotron Radiation Program, ASRP, has been set up as a major national research facility to provide facilities for scientists and technologists in physics, chemistry, biology and materials science who need access to synchrotron radiation. Australia has a strong tradition in crystallography and structure determination covering small molecule crystallography, biological and protein crystallography, diffraction science and materials science and several strong groups are working in x-ray optics, soft x-ray and vacuum ultra-violet physics. A number of groups whose primary interest is in the structure and dynamics of surfaces, catalysts, polymer and surfactant science and colloid science are hoping to use scattering methods and, if experience in Europe, Japan and USA can be taken as a guide, many of these groups will need third generation synchrotron access. To provide for this growing community, the Australian National Beamline at the Photon Factory, Tsukuba, Japan, has been established since 1990 through a generous collaboration with Japanese colleagues, the beamline equipment being largely produced in Australia. This will be supplemented in 1997 with access to the world's most powerful synchrotron x-ray source at the Advanced Photon Source, Argonne National Laboratory, USA. Some recent experiments in surface science using neutrons as well as x-rays from the Australian National Beamline will be used to illustrate one of the challenges that synchrotron x-rays may meet

The Aboriginal and Torres Strait Islander community has an increased risk of developing chronic illnesses including diabetes. Among people with diabetes, foot complications are common and make a significant contribution to the morbidity and mortality associated with this disease. The aim of this review was to systematically evaluate the literature comparing the rates of diabetes related foot complications in Aboriginal and Torres Strait Islander Australians to non-Indigenous Australians. MEDLINE, EMBASE, The Cochrane Library; PUBMED and CINAHL were searched from inception until August 2016. Inclusion criteria were: published cross-sectional or longitudinal studies reporting the prevalence of diabetes related foot complications in both a cohort of Aboriginal and Torres Strait Islander Australians and a cohort of one other Australian population of any age with diabetes. Risk of bias was assessed using the STROBE tool. Eleven studies including a total of 157,892 participants were included. Studies were set in Queensland, the Northern Territory and Western Australia, primarily in rural and remote areas. Aboriginal and Torres Strait Islander Australians experienced substantially more diabetes related foot complications with the mean age up to 14 years younger than non-Indigenous Australians. Aboriginality was associated with increased risk of peripheral neuropathy, foot ulceration and amputation. In several studies, Aboriginal and Torres Strait Islander Australians accounted for the vast majority of diabetes related foot complications (up to 91%) while comprising only a small proportion of the regional population. Reporting quality as assessed with the STROBE tool showed underreporting of: methods, sample description and potential sources of bias. There are no data available for some Australian states and for specific types of diabetes related foot complications. Aboriginal and Torres Strait Islander Australians have a 3-6 fold increased likelihood of experiencing a

Bibliometrics refers to the collection and measurement of publishing and citation data configurations with the goal of quantifying the influence of scholarly activities. Advantages of bibliometrics include the generation of quantitative indicators of impact, productivity, quality and collaboration. Those parties who benefit from the results of bibliometric analysis include researchers, educators, journal publishers, employers and research funding bodies. A bibliometric analysis was completed of peer-reviewed literature from 1991 to 2015, written by Australian occupational therapists (who were able to be identified as such), and indexed in the Science Citation Index-Expanded (SCI-Expanded) or the Social Sciences Citation Index (SSCI) databases. "Occupational therapy" and "occupational therapist(s)" were used as keywords to search journal articles' publication title, abstract, author details, keywords and KeyWord Plus. Between 1991 and 2015, 752 peer-reviewed journal articles were published by Australian occupational therapy authors. On average, those articles had 3.7 authors, 35 references, and were nine pages in length. The top four journals in which Australian occupational therapists published were Australian Occupational Therapy Journal, British Journal of Occupational Therapy, American Journal of Occupational Therapy, and Physical and Occupational Therapy in Paediatrics. The four Australian institutions that generated the largest number of occupational therapy articles were the University of Queensland, University of Sydney, La Trobe University, and Monash University. The top four countries with whom Australian authors collaborated in manuscript writing were the United Kingdom, United States, Canada and Sweden. The volume of occupational therapy peer-reviewed literature has grown over the last two decades. Australian authors have and continue to make significant contributions to the occupational therapy body of knowledge nationally and internationally. © 2018

Philip McLaren and the Indigenous-Australian Crime Novel

Directory of Open Access Journals (Sweden)

Cornelis Martin Renes

2017-01-01

Full Text Available This paper locates the postcolonial crime novel as a space for disenfranchised groups to write back to the marginalisation inherent in the process of colonisation, and explores the example of Australia. From its inception in the mid-19th century, Australian crime fiction reflected upon the challenging harshness and otherness of the Australian experience for the free and convict settler, expelled from the metropole. It created a series of popular subgenres derived from the convict narrative proper, while more ‘standard’ modes of crime fiction, popularised in and through British and American crime fiction, were late to develop. Whereas Australian crime fiction has given expression to the white experience of the continent in manifold ways, up until recently it made no room for Indigenous voices – with the exception of the classic Inspector Napoleon Bonaparte series written by the prolific Arthur Upfield in the first half of the 20th century. For the longest time, this absence reflected the dispossession, dispersal and disenfranchisement of the colonised Indigenous peoples at large; there were neither Aboriginal voices nor Aboriginal authors, which made the textual space of the Australian crime novel a discursive terra nullius. This paper will look at the only Indigenous-Australian author to date with a substantial body of work in crime fiction, Philip McLaren, and elucidate how his four crime novels break new ground in Australian crime fiction by embedding themselves within a political framework of Aboriginal resilience and resistance to neo/colonialism. Written as of the 1990s, McLaren’s oeuvre is eclectic in that it does not respond to traditional formats of Australian crime fiction, shifts between generic subtypes and makes incursions into other genres. The paper concludes that McLaren’s oeuvre has not been conceived of as the work of a crime writer per se, but rather that its form and content are deeply informed by the racist violence

Outlook for the Australian coal market

International Nuclear Information System (INIS)

Anon.

1990-01-01

A shortage of bituminous coal is now being witnessed on the world market, which stems from an increase in demand for it. The prices for bituminous coal, which have been increasing since 1988, will continue to rise in 1990. World coal production in 1989/1990 has been estimated by the Australian Bureau of Mineral Resources at 3,370 million tons, which is 50 million tons more than in the preceding year. Australian experts predict a doubling in world demand for coal by 2025. Many Australian coal mining companies, counting on the increased demand in the future, are taking measures to consolidate production and strengthen their financial base in order to accelerate development of new fields or expand production at existing mines. It is expected that the highest rates of growth in demand will be for power coal. Because of increased world production of steel the demand for coking coal will also rise, but the rates of growth will be much lower than for power coal

Suicide of Australians during the Vietnam War.

2018-04-01

National suicide rates fall during times of war. This fits with the notion of the population coming together against a common foe. But, what happens in the case of a war which is not fully supported, which draws the population and families apart? We consider this question by examining the Australian suicide rates during the divisive Vietnam War. We graphed and examined the Australian suicide figures for 1921-2010. We found clear evidence of a decrease in the suicide rate for World War II (consistent with other studies), but a marked elevation of suicide during the Vietnam War. The elevation of the Australian suicide rate during the Vietnam War is consistent with Durkheim's social integration model - when social integration is lessened, either by individual characteristics or societal characteristics, the risk of suicide rises.

Indigenous Australians, Intellectual Disability and Incarceration: A Confluence of Rights Violations

Claire E. Brolan

2018-02-01

Full Text Available Abstract: This article reviews the health and wellbeing of Aboriginal and Torres Strait Islander Australians with intellectual disability in the Australian prison system through a human rights lens. There is an information gap on this group of Australian prisoners in the health and disability literature and the multi-disciplinary criminal law and human rights law literature. This article will consider the context of Indigenous imprisonment in Australia and examine the status of prisoner health in that country, as well as the status of the health and wellbeing of prisoners with intellectual disability. It will then specifically explore the health, wellbeing and impact of imprisonment on Indigenous Australians with intellectual disability, and highlight how intersectional rights deficits (including health and human rights deficits causally impact the ability of Indigenous Australians with intellectual disability to access due process, equal recognition and justice in the criminal justice and prison system. A central barrier to improving intersectional and discriminatory landscapes relating to health, human rights and justice for Indigenous Australian inmates with intellectual disability, and prisoners with intellectual disability more broadly in the Australian context, is the lack of sufficient governance and accountability mechanisms (including Indigenous-led mechanisms to enforce the operationalisation of consistent, transparent, culturally responsive, rights-based remedies.

Course diversity within South Australian secondary schools as a factor of successful transition and retention within Australian universities

Directory of Open Access Journals (Sweden)

Scott Wright

2010-07-01

Full Text Available There has long been a disparity in the provision of curriculum within Australian secondary schools. This study aims to evaluate whether diversity within schools alters students’ university experiences. While much of the existing literature focuses on each aspect individually, this paper attempts to clarify a link between these factors by focussing on the transition process. A theoretical analysis of key concepts surrounding a web of inter-related issues, including student satisfaction, interest and motivation frames the quantitative data collection. The methodology employed consists of analysing a balanced sample of South Australian secondary schools, from an array of different locations, SES groupings and sizes, and an acknowledgement of previous studies into the first year experience within Australian Universities. The findings suggest that there is a disparity between learning areas in school curricula and an inherent link has been established with issues such as student attrition and dissatisfaction in universities.

Australian law allows for altruistic surrogacy but prohibits compensation of surrogates beyond their expenses, or the use of professional surrogacy agencies. These restrictions limit local access to surrogacy, driving Australians overseas where they can access commercial surrogacy. To assess the Australian public's views regarding the use of gestational surrogacy under various social and medical scenarios, together with their level of support for financial compensation of surrogates and the use of professional surrogacy agencies. Online survey of 500 Australians of reproductive age (18-49 years) regarding views on surrogacy and acceptable levels of compensation, conducted during January 2016. The majority of respondents supported access to surrogacy for couples, irrespective of a couple's marital status or sexuality, with only 9% believing that surrogacy was unjustified under any circumstances. Of those who held a view on compensated surrogacy, over half (58%) believed the current ban was unjustified, with close to two-thirds (62%) also believing that Australians should be allowed to access commercial surrogacy overseas. In relation to compensation, most believed that payment should be determined by negotiation between the surrogate and commissioning parents, while also supporting additional payments for 'hardship' pregnancies. Half of the surveyed cohort supported the legalisation of professional surrogacy agencies, with only 17% being totally opposed. The majority of Australians support surrogacy, compensation for surrogates and professional surrogacy agencies. Therefore, the existing legal restrictions should be replaced with professional guidelines that protect the surrogate and commissioning parents, while also improving Australians' access to surrogacy. © 2016 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Uranium: a notable Australian decision

Energy Technology Data Exchange (ETDEWEB)

Willheim, E

1978-07-01

Australia, with 20% of the world's known reserves, has legislated strict controls for the mining, milling, and export of its uranium deposits. Background information on the environmental inquiry preceding this legislation is reviewed, including a description of the Australian Environmental Protection Act and the Ranger Uranium Environmental Inquiry. A package of six bills implemented the Australian government's decisions on: (1) nuclear proliferation and safeguards, (2) mining in the Kakadu National Park wilderness area, (3) economic and social protection of the Aboriginal people, (4) nuclear waste disposal, (5) security from nuclear terrorism, and (6) environmental controls. The author concludes that the decision and implementing legislation were improved as a result of the public environmental inquiry technique.

2012-01-01

The expression and purification of Epstein–Barr virus BHRF1 as well as its co-crystallization with a peptidomimetic are described. BHRF1 is a pro-survival Bcl-2 homologue encoded by Epstein–Barr virus (EBV) that plays a key role in preventing premature host cell death during viral infection and may contribute to the development of malignancies associated with chronic EBV infections. The anti-apoptotic action of BHRF1 is based on its ability to sequester pro-apoptotic Bcl-2 family proteins, in particular Bim and Bak. These interactions have been previously studied in three dimensions by determining crystal structures of BHRF1 in complex with both Bim and Bak BH3 domains. Screening of a library of peptidomimetic compounds based on the benzoylurea scaffold that mimics critical Bim BH3 domain side chains against BHRF1 led to the identification of an inhibitor of BHRF1 that displays micromolar affinity. Single crystals were obtained from the co-crystallization of recombinant BHRF1 protein with this peptidomimetic compound. The crystals belonged to the orthorhombic space group P2 1 2 1 2 1 , with unit-cell parameters a = 66.8, b = 91.1, c = 151.9 Å. Diffraction data were collected to 2.11 Å resolution on the MX2 beamline at the Australian Synchrotron

The majority of survey respondents who selected bullying as an ethical issue were permanent full time employees (N= 413, 65.6%. A significant relationship was found between respondents identifying bullying as an ethical issue in the survey and their job classification (Deviance = 25.55, Df = 11, p=0.0076, suggesting that job classification, among other things, does predict respondents’ selection of bullying. Furthermore, our survey and interview findings indicate that the more mature respondents, as well as those in the managerial roles, have a greater concern about bullying.

The gambling behavior of indigenous Australians.

Science.gov (United States)

Hing, Nerilee; Breen, Helen; Gordon, Ashley; Russell, Alex

2014-06-01

The gambling activities of minority groups such as Indigenous peoples are usually culturally complex and poorly understood. To redress the scarcity of information and contribute to a better understanding of gambling by Indigenous people, this paper presents quantitative evidence gathered at three Australian Indigenous festivals, online and in several Indigenous communities. With support from Indigenous communities, the study collected and analyzed surveys from 1,259 self-selected Indigenous adults. Approximately 33 % of respondents gambled on card games while 80 % gambled on commercial gambling forms in the previous year. Gambling participation and involvement are high, particularly on electronic gaming machines (EGMs), the favorite and most regular form of gambling. Men are significantly more likely to participate in gambling and to gamble more frequently on EGMs, horse/dog races, sports betting and instant scratch tickets. This elevated participation and frequency of gambling on continuous forms would appear to heighten gambling risks for Indigenous men. This is particularly the case for younger Indigenous men, who are more likely than their older counterparts to gamble on EGMs, table games and poker. While distinct differences between the gambling behaviors of our Indigenous sample and non-Indigenous Australians are apparent, Australian Indigenous behavior appears similar to that of some Indigenous and First Nations populations in other countries. Although this study represents the largest survey of Indigenous Australian gambling ever conducted in New South Wales and Queensland, further research is needed to extend our knowledge of Indigenous gambling and to limit the risks from gambling for Indigenous peoples.

Aboriginal Agency and Marginalisation in Australian Society

Directory of Open Access Journals (Sweden)

Terry Moore

2014-09-01

Full Text Available It is often argued that while state rhetoric may be inclusionary, policies and practices may be exclusionary. This can imply that the power to include rests only with the state. In some ways, the implication is valid in respect of Aboriginal Australians. For instance, the Australian state has gained control of Aboriginal inclusion via a singular, bounded category and Aboriginal ideal type. However, the implication is also limited in their respect. Aborigines are abject but also agents in their relationship with the wider society. Their politics contributes to the construction of the very category and type that governs them, and presses individuals to resist state inclusionary efforts. Aboriginal political elites police the performance of an Aboriginality dominated by notions of difference and resistance. The combined processes of governance act to deny Aborigines the potential of being both Aboriginal and Australian, being different and belonging. They maintain Aborigines’ marginality.

Obstetric and psychosocial risk factors for Australian-born and non-Australian born women and associated pregnancy and birth outcomes: a population based cohort study.

One in four Australians is born overseas and 47% are either born overseas or have a parent who was. Obstetric and psychosocial risk factors for these women may differ. Data from one Sydney hospital (2012-2013) of all births recorded in the ObstetriX database were analysed (n = 3,092). Demographics, obstetric and psychosocial risk profile, obstetric interventions and complications and selected maternal and neonatal outcomes were examined for women born in Australia and overseas. Women born in Australia were younger, more likely to be primiparous (28.6 v 27.5%), be obese (32.0% v 21.4%), smoke (19.7 % v 3.0%), have an epidural (26.2% v 20.2%) and were less likely to have gestational diabetes mellitus (GDM) (6.8% v 13.7% when compared to non-Australian born women. The highest rates of GDM, Gestational Hypertension (GH) and maternal anaemia were seen in women born in China, the Philippines and Pakistan respectively. Differences were also seen in psychosocial screening between Australian and non-Australian women with Australian-born women more likely to smoke and report a mental health disorder. There was an association between having an Edinburgh Postnatal Depression Scale (EPDS) ≥ 13 and other psychosocial issues, such as thoughts of self-harm, domestic violence, childhood abuse etc. These women were also less likely to breastfeed. Women with an EPDS ≥ 13 at booking compared to women with EPDS ≤12 had a higher chance of being diagnosed with GDM (AOR 1.85 95% CI 1.14-3.0). There are significant differences in obstetric and psychosocial risk profiles and maternal and neonatal outcomes between Australian-born and non-Australian born women. In particular there appears to be an association between an EPDS of ≥13 and developing GDM, which warrants further investigation.

To provide local data on visual acuity and surgical outcomes for cataract surgery performed in an Australian teaching hospital. Continuous audit over 7 years in a public teaching hospital. A total of 3740 eyes had cataract surgery performed at The Queen Elizabeth Hospital, South Australia, from May 2006 to September 2013. Visual acuity and complication rates were recorded for cataract surgery cases operated on between May 2006 and September 2013 on a digital database with data entry contemporaneous with final follow-up. Visual acuity and surgical complications. Of the patients, 91.4% achieved postoperative best-measured vision better than preoperative best-measured vision. The rate of posterior capsular tear was 2.59%, endophthalmitis was 0.11% and the overall complication rate was 11.7%. This audit is the first to document modern cataract surgery, overwhelmingly dominated by phacoemulsification in an Australian population and can be used to benchmark cataract surgery outcome in an urban Australian population. © 2015 Royal Australian and New Zealand College of Ophthalmologists.

Australian Muslim civil society organisations: Pathways to social inclusion

Directory of Open Access Journals (Sweden)

Nora Shikeen Amath

2015-09-01

Full Text Available There is great interest on issues related to Muslims and Islam; however, a large concentration of the scholarly literature as well as media and political discourses focus predominantly on political issues and actions related to fundamentalism, radicalisation, militancy and terrorism. The dominance of these issues in the discourses does not provide a holistic understanding of Muslims, particularly their role, place and identity as minorities in a Western society. Indeed, we know relatively little about the larger number of Muslim political actors engaged in civil society, especially those involved in creating pathways to social inclusion. Utilising descriptive phenomenology, this paper explores the complex issues of social inclusion and the Australian Muslim communities. Underpinning this discussion is the theory of social capital; as noted by a number of scholars and social policy experts, the theory of social inclusion alone is inadequate and ineffective in creating participation, equality and cohesion. This paper also observes that while many reports and studies provide pragmatic suggestions on how to work towards the social inclusion of Australian Muslims, the concentration on these suggestions tend to focus on how the government can provide these solutions. What is lacking in the literature is the recognition of the Australian Muslim community’s role and agency in initiating and executing the programs needed to address such issues of social exclusion. The 30 unstructured phenomenological interviews demonstrate that Australian MCSOs are proactively engaging with their communities to ensure that they are responding appropriately to these issues. Moreover, they are creating pathways and access for Australian Muslims to better participate, engage in and contribute to mainstream society. In particular, the MCSO actors revealed four themes related to social inclusion: supporting participation in education and training, facilitating participation

No studies to date have explored the association of vision with mortality in Indigenous Australians. We aimed to determine the 10-year all-cause mortality and its associations among Indigenous Australians living in Central Australia. Prospective observational cohort study. A total of 1257 (93.0%) of 1347 patients from The Central Australian Ocular Health Study, over the age of 40 years, were available for follow-up during a 10-year period. All-cause mortality and its associations with visual acuity, age and gender were analysed. All-cause mortality. All-cause mortality was 29.3% at the end of 10 years. Mortality increased as age of recruitment increased: 14.2% (40-49 years), 22.6% (50-59 years), 50.3% (60 years or older) (χ = 59.15; P < 0.00001). Gender was not associated with mortality as an unadjusted variable, but after adjustment with age and visual acuity, women were 17.0% less likely to die (t = 2.09; P = 0.037). Reduced visual acuity was associated with increased mortality rate (5% increased mortality per one line of reduced visual acuity; t = 4.74; P < 0.0001) after adjustment for age, sex, diabetes and hypertension. The 10-year all-cause mortality rate of Indigenous Australians over the age of 40 years and living in remote communities of Central Australia was 29.3%. This is more than double that of the Australian population as a whole. Mortality was significantly associated with visual acuity at recruitment. Further work designed to better understand this association is warranted and may help to reduce this disparity in the future. © 2016 Royal Australian and New Zealand College of Ophthalmologists.

The Australian radiation protection and Nuclear Safety Agency

International Nuclear Information System (INIS)

Macnab, D.; Burn, P.; Rubendra, R.

1998-01-01

The author talks about the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), the new regulatory authority which will combine the existing resources of the Australian Radiation Laboratory and the Nuclear Safety Bureau. Most uses of radiation in Australia are regulated by State or Territory authorities, but there is presently no regulatory authority for Commonwealth uses of radiation. To provide for regulation of the radiation practices of the Commonwealth, the Australian Government has decided to establish the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) and a Bill has passed through the House of Representatives and will go to the Spring sitting of the Senate. The new agency will subsume the resources and functions of the Nuclear Safety Bureau and the Australian Radiation Laboratory, with additional functions including the regulation of radiation protection and nuclear safety of Commonwealth practices. Another function of ARPANSA will be the promotion of uniform regulatory requirements for radiation protection across Australia. This will be done by developing, in consultation with the States and Territories, radiation health policies and practices for adoption by the Commonwealth, States and Territories. ARPANSA will also provide research and services for radiation health, and in support of the regulatory and uniformity functions. The establishment of ARPANSA will ensure that the proposed replacement research reactor, the future low level radioactive waste repository and other Commonwealth nuclear facilities and radiation practices are subject to a regulatory regime which reflects the accumulated experience of the States and Territories and best international practice, and meets public expectations

Exposure to radon in Australian tourist caves

International Nuclear Information System (INIS)

Solomon, S.B.; Langroo, R.; Lyons, R.G.

1994-01-01

In 1991 the International Commission on Radiological Protection(ICRP) produced guidelines and recommendations dealing with workplace exposure to elevated background radiation, in particular, the risk associated with the inhalation of radon and radon progeny. An intervention level of 1000 Bq m -3 has been proposed. Australia has over 40 tourist caves, under the management of the various State Departments or private groups. The limited data available on radon levels in Australian caves would suggest that some of these caves may be in excess of the proposed intervention level, thus presenting a potential health risk for the cave guides. This paper summarises the current information on radon in Australian caves and describes the proposed methodologies to be used for a Worksafe Australia-funded survey of radon levels in Tourist caves within Australia. This survey is to be carried out jointly by researchers at the Australian Radiation Laboratory, University of Auckland and the University of Sydney, during 1994 and 1995. 7 refs., 3 tabs

2000-12-01

This paper presents an overview of the development in Australia of resistance bolometer technology and associated uncooled infrared sensors. A summary is given of research achievements, with the aim of placing in historic perspective Australian work in comparison with overseas research and development. Extensive research in this field was carried out at the Defence Science and Technology Organisation (DSTO), Salisbury, South Australia, in collaboration with the Australian microelectronic and electro-optic industries, with supporting research in Australian universities. The DSTO research has a history covering five decades, commencing with simple thin film bolometers employed in radiometric sensors, followed by protracted R&D culminating in development of micromachined focal plane detector arrays for non-imaging sensors and lightweight thermal imagers. DSTO currently maintains a microbolometer processing capability for the purposes of research collaboration and support for commercial initiatives based on patented technology. Expertise in microbolometer design, performance and processing technology has transferred to Electro-optic Sensor Design (EOSD) through a licensing agreement. Contemporary development will be described.

The first OZCOTS conference in 1998 was inspired by papers contributed by Australians to the 5th International Conference on Teaching Statistics. In 2008, as part of the program of one of the first National Senior Teaching Fellowships, the 6th OZCOTS was held in conjunction with the Australian Statistical Conference, with Fellowship keynotes and contributed papers, optional refereeing and proceedings. This venture was so successful that the 7th and 8th OZCOTS were similarly run, conjoined with Australian Statistical Conferences in 2010 and 2012. Authors of papers from these OZCOTS conferences were invited to develop chapters for refereeing and inclusion in this volume. There are sections on keynote topics, undergraduate curriculum and learning, professional development, postgraduate learning, and papers from OZCOTS 2012. Because OZCOTS aim to unite statisticians and statistics educators, the approaches this volume takes are immediately relevant to all who have a vested interest in good teaching practices. Glo...

To assess management practices and movement patterns that could influence the establishment and spread of exotic animal diseases (EAD) in pigs in Australia. A literature review of published information and a telephone survey of 370 pig producers owning >10 pigs who were registered with the PigPass national vendor declaration scheme. The movement and marketing patterns of Australian pig producers interviewed were divided into two groups based predominantly on the size of the herd. Major pig producers maintain closed herds, use artificial insemination and market direct to abattoirs. Smaller producers continue to purchase from saleyards and market to other farms, abattoirs and through saleyards in an apparently opportunistic fashion. The role of saleyards in the Australian pig industry continues to decline, with 92% of all pigs marketed directly from farm to abattoir. This survey described movement patterns that will assist in modelling the potential spread of EAD in the Australian pig industry. Continued movement towards vertical integration and closed herds in the Australian pig industry effectively divides the industry into a number of compartments that mitigate against the widespread dissemination of disease to farms adopting these practices. © 2014 Australian Veterinary Association.

1997-01-01

The Australian workplace has emerged as an important venue for influencing the health of employees through regulations and behaviour change programs. Recent surveys have highlighted a growth in this activity but the effectiveness of these programs in changing unhealthy work practices and policies is questionable. The need for strengthening programs by stronger designs and evaluation, and addressing organisational factors and employee participation in planning and implementation processes is documented. Efforts in that direction in Queensland are cited, Building on these existing foundations, redirecting existing resources, and building intersectoral cooperation in public-private partnerships hold a creative, exemplary vision of the future for Australian workplace programming.

Dunphy, Jillian L

2013-05-01

Identify strategies to implement change across the Australian healthcare sector to better support social and natural environments. Methods. Qualitative analysis of semi-structured interviews with Australian healthcare professionals. Interviewees described multiple barriers to implementing change and numerous strategies to overcome these barriers. They argued that action must be taken at the individual and systemic levels to produce substantial and effective change. The strategies recommended fall into four main categories: altering workplace cultures and professional identities, community engagement, political activity, and change from within. The overarching goals of these strategies are to reduce negative impacts on the natural environment, and increase social equity within and across generations. By implementing the strategies described, a more cohesive effort to address sustainability issues across the sector can be made. This may improve local and global health, within current and future generations. WHAT IS KNOWN ABOUT THE TOPIC? Healthcare has a significant impact on the natural and social environments, which in turn have a significant impact upon health and healthcare. WHAT DOES THIS PAPER ADD? This paper describes strategies to alter healthcare to better support environmental sustainability. WHAT ARE THE IMPLICATIONS FOR PRACTITIONERS? Collective implementation of the described strategies may allow a more cohesive and effective response across the Australian healthcare sector, to enhance local and global health for current and future generations.

Fragmentation in Australian Commonwealth and South Australian State policy on mental health and older people: A governmentality analysis

2016-01-01

Mental health care for older people is a significant and growing issue in Australia and internationally. This article describes how older people’s mental health is governed through policy discourse by examining Australian Commonwealth and South Australian State government policy documents, and commentaries from professional groups, advocacy groups and non-governmental organisations. Documents published between 2009 and 2014 were analysed using a governmentality approach, informed by Foucault. Discourses of ‘risk’, ‘ageing as decline/dependence’ and ‘healthy ageing’ were identified. Through these discourses, different neo-liberal governmental strategies are applied to ‘target’ groups according to varying risk judgements. Three policy approaches were identified where older people are (1) absent from policy, (2) governed as responsible, active citizens or (3) governed as passive recipients of health care. This fragmented policy response to older people’s mental health reflects fragmentation in the Australian policy environment. It constructs an ambiguous place for older people within neo-liberal governmental rationality, with significant effects on the health system, older people and their carers. PMID:27147440

The ongoing challenge for ED leaders is to remain abreast of system-wide changes that impact on the day-to-day management of their departments. Changes to the funding model creates another layer of complexity and this introductory paper serves as the beginning of a discussion about the way in which EDs are funded and how this can and will impact on business decisions, models of care and resource allocation within Australian EDs. Furthermore it is evident that any funding model today will mature and change with time, and moves are afoot to refine and contextualise ED funding over the medium term. This perspective seeks to provide a basis of understanding for our current and future funding arrangements in Australian EDs. © 2014 Australasian College for Emergency Medicine and Australasian Society for Emergency Medicine.

Playing With Antidepressants: Perspectives From Indian Australians and Anglo-Australians Living With Depression.

Science.gov (United States)

Brijnath, Bianca; Antoniades, Josefine

2017-11-01

Patient perspectives were explored on the meaning and experience of antidepressant use by applying Johan Huizinga's theory of play to interviews from Indian Australians and Anglo-Australians diagnosed with depression. Through the analysis, the centrality of Huizinga's "magic circle" emerged, that is, defining the boundaries within which one could safely play. Consumption of antidepressants involved learning, breaking, and modulating rules of the game of adherence, then forging a new "magic circle." In these games, there were playful elements including experimentation, improvisation, absorption, and experiential learning. This application of Huizinga's theory in relation to antidepressant use is a novel approach in the literature on medication non/adherence. This application not only opens a new theoretical line of inquiry but also shows that antidepressant non/adherence is not a static practice but dynamic and changing, revealing critical insights around participant's agency, capabilities, desires, and notions of selfhood with regard to managing their depression and conceptualizing their recovery.

Balaratnasingam, Sivasankaran; Janca, Aleksandar

2017-01-01

To examine the validity of concept and diagnosis of personality disorder in transcultural settings using Indigenous Australian people as an example. There are significant deficits in comparative research on personality disorders across cultures. There is also a dearth of information regarding Indigenous Australians, and cultural applicability and clinical utility of the diagnosis of personality disorder in this group. The concept of culture is generally ignored when making a diagnosis of personality disorder. A valid diagnosis should incorporate what would be considered understandable and adaptive behavior in a person's culture. In Indigenous Australian culture, making diagnosis of a personality disorder is complicated by historical trauma from colonization, disruption of kinship networks, and ongoing effects of poverty and social marginalization.

Moral autonomy in Australian legislation and military doctrine

Directory of Open Access Journals (Sweden)

Richard Adams

2013-09-01

Full Text Available Australian legislation and military doctrine stipulate that soldiers ‘subjugate their will’ to government, and fight in any war the government declares. Neither legislation nor doctrine enables the conscience of soldiers. Together, provisions of legislation and doctrine seem to take soldiers for granted. And, rather than strengthening the military instrument, the convention of legislation and doctrine seems to weaken the democratic foundations upon which the military may be shaped as a force for justice. Denied liberty of their conscience, soldiers are denied the foundational right of democratic citizenship and construed as utensils of the State. This article critiques the idea of moral agency in Australian legislation and military doctrine and is concerned with the obligation of the State to safeguard the moral integrity of individual soldiers, so soldiers might serve with a fully formed moral assurance to advance justice in the world. Beyond its explicit focus on the convention of Australian thought, this article raises questions of far-reaching relevance. The provisos of Australian legislation and doctrine are an analogue of western thinking. Thus, this discussion challenges many assumptions concerning military duty and effectiveness. Discussion will additionally provoke some reassessment of the expectations democratic societies hold of their soldiers.

It is well established from different population-based studies that visual impairment is associated with increased mortality rate. However, to our knowledge, the association of visual impairment with increased mortality rate has not been reported among indigenous Australian individuals. To assess the association between visual impairment and 10-year mortality risk among the remote indigenous Australian population. Prospective cohort study recruiting indigenous Australian individuals from 30 remote communities located within the central Australian statistical local area over a 36-month period between July 2005 and June 2008. The data were analyzed in January 2017. Visual acuity, slitlamp biomicroscopy, and fundus examination were performed on all patients at recruitment. Visual impairment was defined as a visual acuity of less than 6/12 in the better eye. Mortality rate and mortality cause were obtained at 10 years, and statistical analyses were performed. Hazard ratios for 10-year mortality with 95% confidence intervals are presented. One thousand three hundred forty-seven patients were recruited from a total target population number of 2014. The mean (SD) age was 56 (11) years, and 62% were women. The total all-cause mortality was found to be 29.3% at 10 years. This varied from 21.1% among those without visual impairment to 48.5% among those with visual impairment. After adjustment for age, sex, and the presence of diabetes and hypertension, those with visual impairment were 40% more likely to die (hazard ratio, 1.40; 95% CI, 1.16-1.70; P = .001) during the 10-year follow-up period compared with those with normal vision. Bilateral visual impairment among remote indigenous Australian individuals was associated with 40% higher 10-year mortality risk compared with those who were not visually impaired. Resource allocation toward improving visual acuity may therefore aid in closing the gap in mortality outcomes between indigenous and nonindigenous Australian

Bernath, Paul

2003-02-01

This article argues that existing Australian regulations do not adequately cover online pharmacies or Internet advertising of medicines and that existing penalties and sanctions are often ineffective, potentially placing public health and safety at risk. Suggestions are made for future regulatory approaches. It is concluded that as well as an effective program of public education, cautious domestic legislative reform is necessary to ensure specific regulation of Australian online pharmacy practice and Internet advertising of medicines. In addition, the global nature of the Internet demands international co-operation and increased regulator and consumer vigilance.

Full Text Available In this work, a novel membrane crystallization system was used to crystallize micro-sized seeds of piroxicam monohydrate by reverse antisolvent addition. Membrane crystallization seeds were compared with seeds produced by conventional antisolvent addition and polymorphic transformation of a fine powdered sample of piroxicam form I in water. The membrane crystallization process allowed for a consistent production of pure monohydrate crystals with narrow size distribution and without significant agglomeration. The seeds were grown in 350 g of 20:80 w/w acetone-water mixture. Different seeding loads were tested and temperature cycling was applied in order to avoid agglomeration of the growing crystals during the process. Focused beam reflectance measurement (FBRM; and particle vision and measurement (PVM were used to monitor crystal growth; nucleation and agglomeration during the seeded experiments. Furthermore; Raman spectroscopy was used to monitor solute concentration and estimate the overall yield of the process. Membrane crystallization was proved to be the most convenient and consistent method to produce seeds of highly agglomerating compounds; which can be grown via cooling crystallization and temperature cycling.

To obtain information on the types of Australian horses, how they are kept and their activities. An invitation to participate in an opt-in, internet-based survey was sent to 7000 people who had registered an email address to receive information from the Australian Horse Industry Council Inc. There were 3377 (48%) useable responses from owners of 26,548 horses. Most horses were kept on small properties (usually 2-8 ha) in paddocks in rural areas of Queensland, New South Wales and Victoria. Most horses were female or geldings and the most common of 54 different activities was breeding. Owners reported 19,291 horses were used in different activities and 6037 (23%) horses were not kept for any stated purpose or activity. Owners used an average of 1.95 horses in 2.9 different types of activities. The most common of the 43 breeds were Thoroughbred, Australian Stock Horse and Australian Quarter Horse. Only 1% of the total numbers of Thoroughbreds and Standardbreds in this survey were used in horse racing, indicating there is a demand for these breeds in non-racing activities. Microchip was the most favoured method of horse identification and 36% favoured compulsory registration of horses. Most respondents reported owning some other animal species. There is a wide variation in horse breeds used in different activities by Australian horse owners. There are regional differences in various management systems. There needs to be considerable improvement in the collection and recording of information to improve the validity and reliability of horse industry data. © 2016 Australian Veterinary Association.

The International Adaptation Trial (IAT) is a special purpose nursery designed to investigate the genotype-by-environment interactions and worldwide adaptation for grain yield of Australian and CIMMYT spring bread wheat (Triticum aestivum L.) and durum wheat (T. turgidum L. var. durum). The IAT contains lines representing Australian and CIMMYT wheat breeding programs and was distributed to 91 countries between 2000 and 2004. Yield data of 41 reference lines from 106 trials were analysed. A multiplicative mixed model accounted for trial variance heterogeneity and inter-trial correlations characteristic of multi-environment trials. A factor analytic model explained 48% of the genetic variance for the reference lines. Pedigree information was then incorporated to partition the genetic line effects into additive and non-additive components. This model explained 67 and 56% of the additive by environment and non-additive by environment genetic variances, respectively. Australian and CIMMYT germplasm showed good adaptation to their respective target production environments. In general, Australian lines performed well in south and west Australia, South America, southern Africa, Iran and high latitude European and Canadian locations. CIMMYT lines performed well at CIMMYT's key yield testing location in Mexico (CIANO), north-eastern Australia, the Indo-Gangetic plains, West Asia North Africa and locations in Europe and Canada. Maturity explained some of the global adaptation patterns. In general, southern Australian germplasm were later maturing than CIMMYT material. While CIANO continues to provide adapted lines to northern Australia, selecting for yield among later maturing CIMMYT material in CIANO may identify lines adapted to southern and western Australian environments.

Incentives for industrial R&D: The Australian experience

OpenAIRE

Peter Hall

1996-01-01

The effects of Australian measures to influence investment in industrial R&D (IRD) are anafysed. Australian experience tends to suggest that, while selective schemes have performed a little better than a tax concession alone, the advantage to selectivity would look less pronounced if general incentives were extended at an appropriate rate to firms in tax loss. Even with relatively low inducement rates, such incentives appear to have the advantage, from an evolutionary perspective, of encourag...

The Australian cigarette brand as product, person, and symbol

Science.gov (United States)

Carter, S

2003-01-01

Objective: To examine, for dominant Australian cigarette brands, brand identity (overriding brand vision), brand positioning (brand identity elements communicated to the consumer), brand image (consumers' brand perceptions) and brand equity (financial value). Design: Tobacco industry documents, articles from retail trade publications since 1990, and current brand advertising from retail trade publications were searched for information about Australian brands. Results: Cigarette manufacturers benefit from their competitors' brand equity as well as their own. The industry sees Australian smokers as far less brand loyal and strongly oriented to "low tar". A few predominantly local brands dominate the market, with variation by state. Successful Australian brands exist in one of three categories: premium, mainstream, and supervalue. Their brand identity essence is as follows. Premium: quality. Mainstream: a good humoured "fair go" for ordinary Australians. Supervalue: value for money. All supervalue brand identities also include freedom, escape, mildness, an aspirational attitude, blue tones, and waterside scenes. Brand image and brand identity is frequently congruent, even when marketing is restricted, and brand image is generally more positive for a smoker's own brand. Conclusions: Tobacco control activities have undermined cigarette brand equity. Further research is needed regarding brand loyalty, low tar, and brand categories. Smokers may respond more positively to tobacco control messages consistent with the identities of their chosen brand, and brand-as-organisation elements may assist. Further marketing restrictions should consider all elements of brand identity, and aim to undermine brand categories. PMID:14645952

Recently Fayers introduced a large family of combinatorial realizations of the fundamental crystal B(Λ0) for ^sln, where the vertices are indexed by certain partitions. He showed that special cases of this construction agree with the Misra-Miwa realization and with Berg's ladder crystal. Here we show that another special case is naturally isomorphic to a realization using Nakajima's monomial crystal.

This study investigated whether lifetime and recent methamphetamine use (including crystal methamphetamine) differed among city, regional and rural residents and whether particular subpopulations were more at-risk. Secondary analyses of the last three National Drug Strategy Household Surveys and corresponding Alcohol and Other Drug Treatment Services National Minimum Data Sets (AODTS NMDS). Australian general population. Australians who completed the 2007 (n = 22 519), 2010 (n = 25 786) and 2013 (n = 23 512) NDSHS (aged 14 + ); and treatment episodes where the principal drug of concern was recorded in the 2006/2007 (n = 139 808), 2009/2010 (n = 139 608) and 2012/2013 (n = 154 489) AODTS NMDS. To determine whether rural Australians were more likely to use methamphetamine than non-rural counterparts. Lifetime and recent methamphetamine and recent crystal methamphetamine use were significantly higher among rural than other Australians. Significantly more rural men and employed rural Australians used methamphetamine than their city, regional or Australian counterparts. Rural Australians aged 18-24 and 25-29 years were significantly more likely to have used methamphetamine in their lifetime than city or Australian residents. Rural Australians aged 18-24 years were significantly more likely to have recently used crystal methamphetamine. Interventions tailored to address the specific and unique circumstances of rural settings are required to reduce and prevent methamphetamine use, particularly crystal methamphetamine. Scope exists to focus prevention efforts on rural workplaces and primary care settings. Greater understanding of the higher prevalence of methamphetamine use in rural areas is required, plus implementation of comprehensive strategies and optimised treatment utilisation. © 2016 National Rural Health Alliance Inc.

2012-01-01

Full Text Available Interpreting the Australian fiction, we have suggested that some blossoming of this Australian genre happened during the nineteenth century, so in this review we have to start with some earlier works to express the cultural and poetical picture just unpretentious but completely. Firstly, it ought to be the Aboriginal literature which is of great importance to many both within Australia and internationally. This culture review will relate to the Aboriginal writing in English. The transformative survey of Aboriginal writing presents the stories and patterns of Australian culture and society in new ways, foregrounding and celebrating Indigenous experience and expression. It introduces powerful and creative individual voices as it also reveals a larger history of struggle, suffering and strength.

Dang, H Q; Constantine, S; Anderson, P J

2017-06-01

The aim of this study was to determine the prevalence of dental anomalies within an Australian paediatric population using panoramic radiographs. This was a prospective review of 1050 panoramic radiographs obtained as part of a school dental screening program in suburban and rural New South Wales, Australia. Fifty-four (5.14%) patients had a dental anomaly present. Agenesis was noted to have occurred 69 times across 45 patients (4.28%), along with seven cases of impaction (0.6%) and three cases of supernumerary teeth (0.28%). Dental anomalies rarely occur in the Australian population, which possesses a wide-ranging multiethnic cohort. Despite their rarity, they can be incidentally discovered so identification and management by dental practitioners are important. © 2016 Australian Dental Association.

The Beginnings of Australian Radio Astronomy

Science.gov (United States)

Sullivan, Woodruff T.

The early stages of Australian radio astronomy, especially the first decade after World War II, are described in detail. These include the transition of the CSIRO Radiophysics Laboratory, under the leadership of Joseph Pawsey and Taffy Bowen, from a wartime laboratory in 1945 to, by 1950, the largest and one of the two most important radio astronomy groups in the world (with the Cavendish Laboratory at Cambridge University). The initial solar investigations are described, including discovery of the hot corona and development of the sea-cliff interferometer. During this same period painstaking `radio star' observations by John Bolton and colleagues led to the first suggested optical identifications of Taurus-A (the Crab Nebula), Centaurus-A (NGC 5128), and Virgo-A (M87). The factors that led to the extraordinary early success of the Radiophysics Laboratory are analyzed in detail, followed by discussion of how the situation changed significantly in the second decade of 1955-1965. Finally, the development of major Australian instruments, from the Parkes Radio Telescope (1961) to the Australia Telescope (1988), is briefly presented. This chapter is a direct reprint of the following research paper: Sullivan, W., 2005. The beginnings of Australian radio astronomy. Journal of Astronomical History and Heritage, 8, 11-32.

Unifying the crystallization behavior of hexagonal and square crystals with the phase-field-crystal model

International Nuclear Information System (INIS)

Yang Tao; Chen Zheng; Zhang Jing; Wang Yongxin; Lu Yanli

2016-01-01

By employing the phase-field-crystal models, the atomic crystallization process of hexagonal and square crystals is investigated with the emphasis on the growth mechanism and morphological change. A unified regime describing the crystallization behavior of both crystals is obtained with the thermodynamic driving force varying. By increasing the driving force, both crystals (in the steady-state) transform from a faceted polygon to an apex-bulged polygon, and then into a symmetric dendrite. For the faceted polygon, the interface advances by a layer-by-layer (LL) mode while for the apex-bulged polygonal and the dendritic crystals, it first adopts the LL mode and then transits into the multi-layer (ML) mode in the later stage. In particular, a shift of the nucleation sites from the face center to the area around the crystal tips is detected in the early growth stage of both crystals and is rationalized in terms of the relation between the crystal size and the driving force distribution. Finally, a parameter characterizing the complex shape change of square crystal is introduced. (paper)

Chlorophyll a is the most commonly used indicator of phytoplankton biomass in the marine environment. It is relatively simple and cost effective to measure when compared to phytoplankton abundance and is thus routinely included in many surveys. Here we collate 173, 333 records of chlorophyll a collected since 1965 from Australian waters gathered from researchers on regular coastal monitoring surveys and ocean voyages into a single repository. This dataset includes the chlorophyll a values as measured from samples analysed using spectrophotometry, fluorometry and high performance liquid chromatography (HPLC). The Australian Chlorophyll a database is freely available through the Australian Ocean Data Network portal (https://portal.aodn.org.au/). These data can be used in isolation as an index of phytoplankton biomass or in combination with other data to provide insight into water quality, ecosystem state, and relationships with other trophic levels such as zooplankton or fish.

Si, Si; Peters, Susan; Reid, Alison

2018-07-01

Australia's use and consumption of asbestos occurred at the same time as its immigration boom. Our objective was to investigate mesothelioma death rates among migrants and Australian-born between 1981 and 2012. Australian national mesothelioma deaths from 1981 to 2002 and 2006 to 2012 together with national censuses from 1981 to 2011 were extracted and combined. Directly standardised rates and negative binomial regression were applied examining differences in mesothelioma death rates with regard to country of birth. Migrants from the UK and Ireland, Italy and Germany had significantly higher mesothelioma death rates than Australian-born; lower rates were observed among migrants from other countries. Our findings suggest there may have been differences in occupational health and safety between foreign and Australian-born. Because of changes in the demographics of migrants to Australia since the 1970s and changes in occupational circumstances over time, further comparisons of occupational-related health outcomes between foreign and Australian-born could identify potential occupational inequalities that may still exist today.

A review of the Australian healthcare system: A policy perspective

Science.gov (United States)

Sambasivan, Murali

2018-01-01

This article seeks to review the Australian healthcare system and compare it to similar systems in other countries to highlight the main issues and problems. A literature search for articles relating to the Australian and other developed countries’ healthcare systems was conducted by using Google and the library of Victoria University, Melbourne. Data from the websites of the Commonwealth of Australia, the Australian Institute of Health and Welfare, the Australian Productivity Commission, the Organisation for Economic Co-operation and Development and the World Bank have also been used. Although care within the Australian healthcare system is among the best in the world, there is a need to change the paradigm currently being used to measure the outcomes and allocate resources. The Australian healthcare system is potentially dealing with two main problems: (a) resource allocation, and (b) performance and patient outcomes improvements. An interdisciplinary research approach in the areas of performance measurement, quality and patient outcomes improvement could be adopted to discover new insights, by using the policy implementation error/efficiency and bureaucratic capacity. Hospital managers, executives and healthcare management practitioners could use an interdisciplinary approach to design new performance measurement models, in which financial performance, quality, healthcare and patient outcomes are blended in, for resource allocation and performance improvement. This article recommends that public policy implementation error and the bureaucratic capacity models be applied to healthcare to optimise the outcomes for the healthcare system in Australia. In addition, it highlights the need for evaluation of the current reimbursement method, freedom of choice to patients and a regular scrutiny of the appropriateness of care. PMID:29686869

The study described in this report sets out to determine which Australian show caves have long- term radon levels in excess of the proposed action level of 1000 Bq m{sup -3}. The collaborative study between the Australian Radiation Laboratory (ARL), the University of Sydney and the University of Auckland, was carried out with the support of a Research Grant from Worksafe Australia. The aims of this study were to measure radon levels for each season over a period of one year, at representative sites in all developed show caves around Australia, to determine yearly average radon levels for each cave tour, based on these site measurements, to estimate the radiation doses to the tour guides employed in these caves, and to identify caves with radon concentrations in excess of the action level.

The Store.Synchrotron service, a fully functional, cloud computing-based solution to raw X-ray data archiving and dissemination at the Australian Synchrotron, is described. The service automatically receives and archives raw diffraction data, related metadata and preliminary results of automated data-processing workflows. Data are able to be shared with collaborators and opened to the public. In the nine months since its deployment in August 2013, the service has handled over 22.4 TB of raw data (∼1.7 million diffraction images). Several real examples from the Australian crystallographic community are described that illustrate the advantages of the approach, which include real-time online data access and fully redundant, secure storage. Discoveries in biological sciences increasingly require multidisciplinary approaches. With this in mind, Store.Synchrotron has been developed as a component within a greater service that can combine data from other instruments at the Australian Synchrotron, as well as instruments at the Australian neutron source ANSTO. It is therefore envisaged that this will serve as a model implementation of raw data archiving and dissemination within the structural biology research community.

Astronomical Symbolism in Australian Aboriginal Rock Art

Norris, Ray P.; Hamacher, Duane W.

2011-05-01

Traditional Aboriginal Australian cultures include a significant astronomical component, perpetuated through oral tradition and ceremony. This knowledge has practical navigational and calendrical functions, and sometimes extends to a deep understanding of the motion of objects in the sky. Here we explore whether this astronomical tradition is reflected in the rock art of Aboriginal Australians. We find several plausible examples of depictions of astronomical figures and symbols, and also evidence that astronomical observations were used to set out stone arrangements. However, we recognise that the case is not yet strong enough to make an unequivocal statement, and describe our plans for further research.

Detailed, published surveys specific to Australian breast radiotherapy practice were last conducted in 2002. More recent international surveys specific to breast radiotherapy practice include a European survey conducted in 2008/2009 and a Spanish survey conducted in 2009. Radiotherapy techniques continue to evolve, and the utilisation of new techniques, such as intensity-modulated radiation therapy (IMRT), is increasing. This survey aimed to determine current breast radiotherapy practices across Australia. An online survey was completed by 50 of the 69 Australian radiation therapy treatment centres. Supine tangential beam whole breast irradiation remains the standard of care for breast radiotherapy in Australia. A growing number of institutions are exploring prone positioning and IMRT utilisation. This survey demonstrated a wide variation in the benchmarks used to limit and report organ at risk doses, prescribed dose regimen, and post-mastectomy bolus practices. This survey also indicated, when compared with international literature, that there may be less interest in or uptake of external beam partial breast irradiation, prone positioning, simultaneous integrated boost and breath hold techniques. These are areas where further review and research may be warranted to ensure Australian patients are receiving the best care possible based on the best evidence available. This survey provides insight into the current radiotherapy practice for breast cancer in Australia. © 2015 The Royal Australian and New Zealand College of Radiologists.

An evaluation of the Australian Rotavirus Surveillance Program.

Roberts-Witteveen, April R; Patel, Mahomed S; Roche, Paul W

2008-09-01

The Australian Rotavirus Serotyping Program (ARSP) serotypes rotavirus isolates obtained from stool samples sent from Australian laboratories. In collaboration with ARSP the Australian Government Department of Health and Ageing evaluated the program for its utility and capacity to monitor effectiveness of the rotavirus vaccines recently introduced into the Australian National Immunisation Program. The system was described using ARSP annual reports and staff interviews. The attributes of the system were assessed by adapting standard guidelines for evaluating a surveillance system. Email surveys or face to face interviews were conducted with staff of ARSP, participating laboratories, rotavirus vaccine manufacturing companies and representatives of the Communicable Diseases Network Australia. The ability of the ARSP to monitor changes in rotavirus serotype epidemiology was assessed. ARSP serotypes rotavirus isolates received from participating laboratories at least bi-annually, with results being reported at least as often. Serotype analyses have informed formulation of rotavirus vaccines and contributed to forecasting the extent of outbreaks caused by novel serotypes. The ARSP will be able to monitor changes in rotavirus serotype epidemiology and identify probable vaccination failures. Enhancement of the representativeness and sensitivity of the system are needed for the data to remain useful in the public health context. Methods for transferring data between the program and state and territory health departments need to be developed.

USGS analysis of the Australian UNCLOS submission

Science.gov (United States)

Hutchinson, Deborah R.; Rowland, Robert W.

2006-01-01

In November 2004, the Government of Australia made a submission to the Commission on the Limits of the Continental Shelf (CLCS) for 10 extended continental shelf (ECS) regions, utilizing Article-76 of the United Nations Convention on the Law of the Sea (UNCLOS). With information provided in the Australian Executive Summary, the USGS examined the 10 regions of the submission from geological, morphological, and resource perspectives. By their own request, the Australians asked that CLCS take no action on the Australian-Antarctic Territory. The major limitation in this analysis is that no bathymetric soundings or detailed hydrographic profiles were provided in the Australian Executive Summary that might show why the Foot of the Slope (FOS) was chosen or where the 2,500-m contour is located. This represents a major limitation because more than half of the 4,205 boundary points utilize the bathymetric formula line and more than one-third of them utilize the bathymetric constraint line. CLCS decisions on the components of this submission may set a precedent for how ECSs are treated in future submissions. Some of the key decisions will cover (a) how a 'natural prolongation' of a continental margin is determined, particularly if a bathymetric saddle that appears to determine the prolongation is in deep water and is well outside of the 200-nm limit (Exmouth Plateau), (b) defining to what extent that plateaus, rises, caps, banks and spurs that are formed of oceanic crust and from oceanic processes can be considered to be 'natural prolongations' (Kerguelen Plateau), (c) to what degree UNCLOS recognizes reefs and uninhabited micro-islands (specifically, rocks and/or sand shoals) as islands that can have an EEZ (Middleton and Elizabeth Reefs north of Lord Howe Island), and (d) how the Foot of the Slope (FOS) is chosen (Great Australian Bight). The submission contains situations that are relevant to potential future U.S. submissions and are potentially analogous to certain

Super-resolution with an optically-addressable liquid crystal spatial light modulator

International Nuclear Information System (INIS)

McOrist, J.; Sharma, M.D.; Sheppard, C.J.R.

2002-01-01

Full text: An optically-addressable liquid crystal spatial light modulator has been used to generate super-resolving masks. This approach avoids problems of low efficiency and coupling between amplitude and phase modulation, that occur when using conventional liquid crystal modulators. When addressed by a programmed light intensity distribution, it allows filters to be changed rapidly to modify the response of a system or permit the investigation of different filter designs. The device used is not pixellated, with a spatial resolution of 30 line pairs/mm over an area 18mm X 18mm, and can achieve continuously-variable phase modulation up to 1.5 wavelengths. The system consists of a write-beam that is collimated from a white-light source. An input mask was used in our experiments determines the modulation pattern of the read-beam. The read-beam from a HeNe laser reflects from the modulator and is focused by a microscope objective. The value of the phase change induced by the transparent regions of the mask can be altered continuously by adjusting the brightness of the write-beam. We have used this system to attain super-resolution by simple Toraldo filters, consisting of arrays of rings. Copyright (2002) Australian Society for Electron Microscopy Inc

Evidence suggests that physical activity (PA) and sedentary behaviour (SB) participation varies among culturally and linguistically diverse (CALD) adolescents. The present study examined differences in PA and SB among a CALD sample of Chinese Australian, South-east Asian and Anglo-Australian adolescents. Data from 286 adolescents aged 12-16 years involved in the Chinese and Australian Adolescent Health Survey in metropolitan Melbourne, Australia, were analysed. Accelerometry outcomes included median activity counts per minute (counts x min(-1)) and minutes per day (min x day(-1)) spent in light-intensity PA (LPA), moderate-to-vigorous-intensity PA (MVPA) and sedentary time (ST). Kruskal-Wallis one-way analysis of variance and sequential multiple hierarchical linear regressions were used to examine CALD differences in PA and ST. Multivariate analyses of accelerometry data found Chinese Australian and South-east Asian adolescents engaged in significantly less daily MVPA (5-8 min x day(-1)) and LPA (50-58 min x day(-1); P Asian adolescents compared with Anglo-Australian adolescents. These findings have important public health implications in furthering our understanding of CALD differences in PA and SB. SO WHAT? An understanding of the CALD differences in physical activity and sedentary behaviour among Australian adolescents has important implications for intervention planning and delivery as well as the wider health implications of these behaviours. This article furthers the current understanding of CALD adolescents' participation in physical activity and sedentary behaviour, of which limited information is available.

A content analysis of oral health messages in Australian mass media.

Jones, Kelly; Merrick, Jessica; Beasley, Christine

2015-01-27

Social analysis regarding oral health and oral health promotion are almost non-existent in the Australian context. The usefulness of such exploration lies in framing and informing research methodologies and health promotion initiatives and can improve our understanding of oral health behaviours and their social contexts. We conducted a systematic content analysis of a random sample of popular Australian magazines, newspapers and television shows from May to September 2012. Our sample included the top three best-selling magazines, six weekly newspapers, one from each available Australian state; and the four highest-ranked Australian prime-time television shows and their associated commercials. Data comprised of 72 hours of prime-time television and 14,628 pages of hardcopy media. 71 oral health related media 'incidents' were counted during a five month period. Only 1.5% of incidents referenced fluoride and only two made dietary references. Women were represented almost six times more than men and the majority of oral health related incidents conveyed no social context (63%). Oral health messages conveyed in Australian media fail to provide a social context for preventative or health-promoting behaviours. In light of increased levels of oral disease and retention of natural teeth, more community-based oral health promotion and support for oral health literacy would be prudent in the Australian context.

Jehlička, J.; Edwards, H. G. M.; Oren, A.

2013-04-01

Laboratory cultures of a number of red extremely halophilic Archaea (Halobacterium salinarum strains NRC-1 and R1, Halorubrum sodomense, Haloarcula valismortis) and of Salinibacter ruber, a red extremely halophilic member of the Bacteria, have been investigated by Raman spectroscopy using 514.5 nm excitation to characterize their carotenoids. The 50-carbon carotenoid α-bacterioruberin was detected as the major carotenoid in all archaeal strains. Raman spectroscopy also detected bacterioruberin as the main pigment in a red pellet of cells collected from a saltern crystallizer pond. Salinibacter contains the C40-carotenoid acyl glycoside salinixanthin (all-E, 2'S)-2'-hydroxy-1'-[6-O-(methyltetradecanoyl)-β-D-glycopyranosyloxy]-3',4'-didehydro-1',2'-dihydro-β,ψ-carotene-4-one), for which the Raman bands assignments of are given here for the first time.

Mackay, S.J.; Baker, R.; Collier, D.; Lewis, S.

2013-01-01

Emotional intelligence (EI) in the UK radiographer workforce has been benchmarked using the trait emotional intelligence model and the profile of the profession in the UK has begun to emerge. There are cultural differences between countries that have been shown to have an effect on EI, therefore this paper aims to benchmark the Global and four factor scores of Trait EI in the Australian radiographer population; to explore any differences within the two main professional groupings, diagnostic and therapeutic radiographers, and to compare the Australian radiographer workforce scores with those of the UK previously published. The published and validated trait EI questionnaire of Petrides was used as the survey tool for the Global EI and the four factors of Well-being, Emotionality, Self-control and Sociability. There was only one difference found in the five factors studied between the UK and Australian radiographer workforce, that of Well-being (p ≤ 0.01). No differences emerged between the diagnostic and therapy disciplines nor was a relationship found between EI and the Australian leadership in contrast to the UK workforce findings. Differences were found in the demographic profiles of the two countries and the implications of the above findings are discussed. This paper has benchmarked the EI of the Australian workforce and found a difference in well-being between the UK and Australian radiographer workforce. The Australian diagnostic and therapy disciplines were no different in their EI profiles. No relationship was found between EI and leadership in the Australian radiographer workforce

Disability management in a sample of Australian self-insured companies.

Science.gov (United States)

Westmorland, M; Buys, N; Clements, N

2002-09-20

Disability management (DM) is a term developed in North America and refers to the prevention and management of injury and illness in the workplace. The purpose of this paper is to report findings of an Australian study that examined whether self-insured employers in that country have implemented integrated DM programmes. Key principles underpinning such programmes are explored to identify the extent to which Australian employers have adopted them. Data was collected from 29 self-insured Australian companies in three Australian States using a structured interview format with additional open-ended questions. It was found that companies have in place, to varying degrees, some of the key elements of disability management programmes. However, these elements were often not well integrated in a comprehensive disability management approach. The focus on workplace-based, early intervention in the area of return to work for injured employees was particularly strong, but there was little evidence of formal labour-management committee structures responsible for implementing DM programmes. If the concept of DM is relevant to the Australian environment then this study would suggest that self-insured companies need to undertake further work to develop integrated approaches to preventing and managing disability in the workplace. Several limitations of this study are highlighted and it is concluded that further work in this area is needed.

2014-02-01

Dietary exposure to heavy metals is a matter of concern for human health risk through the consumption of rice, vegetables and other major foodstuffs. In the present study, we investigated concentrations of cadmium (Cd), cobalt (Co), chromium (Cr), copper (Cu), manganese (Mn), nickel (Ni), lead (Pb), and zinc (Zn) in Australian grown and imported rice and vegetables on sale in Australia. The mean concentrations of Cd, Co, Cr, Cu, Mn, Ni, Pb, and Zn in Australian grown rice were 7.5 µg kg(-1), 21 µg kg(-1), 144 µg kg(-1), 2.9 mg kg(-1), 24.4 mg kg(-1), 166 µg kg(-1), 375 µg kg(-1), and 17.1 mg kg(-1) dry weight (d. wt.), respectively. Except Cd, heavy metal concentrations in Australian grown rice were higher than Bangladeshi rice on sale in Australia. However, the concentrations of Cd, Cr, Cu, and Ni in Indian rice on sale in Australia were higher than Australian grown rice. The concentrations of Cu and Ni in Vietnamese rice, and that of Cd, Cr, Cu, Ni, and Pb in Thai rice on sale in Australia were also higher than Australian grown rice. Heavy metal concentrations in Pakistani rice on sale in Australia were substantially lower than that in Australian grown rice. In Australian grown rice varieties, the concentrations of heavy metals were considerably higher in brown rice varieties than white rice varieties, indicating Australian brown rice as a potential source of dietary heavy metals for Australian consumers. The mean concentrations of heavy metals in Australian grown and Bangladeshi vegetables on sale in Australia were also determined. Some of the Australian grown and Bangladeshi vegetables contained heavy metals higher than Australian standard maximum limits indicating them as potential sources of dietary heavy metals for Australian consumers. Further investigation is required to estimate health risks of heavy metals from rice and vegetables consumption for Australian consumers. © 2013 Published by Elsevier Inc.

The Australian stock market development: Prospects and challenges

Directory of Open Access Journals (Sweden)

Sheilla Nyasha

2013-06-01

Full Text Available This paper highlights the origin and development of the Australian stock market. The country has three major stock exchanges, namely: the Australian Securities Exchange Group, the National Stock Exchange of Australia, and the Asia-Pacific Stock Exchange. These stock exchanges were born out of a string of stock exchanges that merged over time. Stock-market reforms have been implemented since the period of deregulation, during the 1980s; and the Exchanges responded largely positively to these reforms. As a result of the reforms, the Australian stock market has developed in terms of the number of listed companies, the market capitalisation, the total value of stocks traded, and the turnover ratio. Although the stock market in Australia has developed remarkably over the years, and was spared by the global financial crisis of the late 2000s, it still faces some challenges. These include the increased economic uncertainty overseas, the downtrend in global financial markets, and the restrained consumer confidence in Australia.

Correlates of housing affordability stress among older Australians.

Science.gov (United States)

Temple, Jeromey B

2008-03-01

The purpose of this study was to examine the prevalence and correlates of housing affordability stress among community-dwelling older Australians. The 2002 ABS General Social Survey was used to measure the prevalence of housing affordability stress. Rare event logistic regression was used to measure the potential correlates of housing affordability stress. Almost 5% of Australians aged 55 years and older, and 20% of those younger than 55 years, are estimated to experience housing affordability stress. Men and women living alone are more likely to experience affordability stress when compared to couples. Low-income earners, those with a consumer debt or who do not hold assets, are at a heightened risk of such stress. Home ownership, regardless of income, is the strongest buffer against housing affordability problems in old age. Although the prevalence of housing affordability stress is low among older Australians when compared to the younger population, a definite social gradient exists in those at risk.

Environmental impact assessments conducted for Australian mine sites involving naturally occurring radioactive material require an assessment of radiation doses to wildlife. Whole-organism concentration ratios (CR{sub wo}) are pivotal in these assessments and previous reviews have identified a need for a more complete and consolidated database of Australian-specific CR{sub wo} that could be used. Concern had also been expressed by some stakeholders in Australia about the suitability of the default CR{sub wo} values provided in standard biota dose models (e.g., ERICA Tool, RESRAD-BIOTA, ICRP framework) for Australian wildlife and environmental conditions. In order to address these concerns and support the implementation of best-practice standards in environmental radiological assessment, the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA), with support from the Department of Resources, Energy and Tourism (RET), undertook an evaluation of existing data relating to wildlife inhabiting Australian uranium mining environments. CR{sub wo} values were calculated using data from a range of original sources. These included scientific journal publications, technical reports from Australian government organisations, site-specific data from mining operators and data from baseline environmental surveys undertaken during the 1970's and 1980's. The Australian data previously included in the international Wildlife Transfer Database (WTD, www.wildlifetransferdatabase.org) were also reviewed and updated. This paper discusses the data analysis process and associated uncertainties. CR{sub wo} values are reported for uranium, thorium, radium-226, lead-210 and polonium-210 for a range of endemic and introduced wildlife, with a focus on plants and animals from both terrestrial and freshwater environments where uranium mining has been proposed or undertaken. This has resulted in the calculation of more than 500 CR{sub wo} values for inclusion in the database

The decline in Australian young male suicide.

Science.gov (United States)

Morrell, Stephen; Page, Andrew N; Taylor, Richard J

2007-02-01

Since the late 1990s there has been a sharp downward trend in Australian young male suicide. It is possible that a major government youth suicide prevention initiative, the National Youth Suicide Prevention Strategy (NYSPS), implemented during 1995-1999 may have influenced the decline. In this article, we examine time trends in age- and means-specific male and female Australian suicide rates in relation to unemployment rates and the NYSPS. Based on Australian suicide data over the period 1966-2003, we assess secular changes in the 20-24 year male suicide to total (crude) male suicide rate ratio in relation to the NYSPS, using interrupted time series analysis (ARIMA), since this was previously found to be significantly associated with the 20-24 year male unemployment to total employment ratio. Results show that a dramatic reduction in Australian young male (aged 20-34 years) suicide has occurred since 1997-1998, declining from approximately 40 per 100,000 in 1997-1998 to approximately 20 per 100,000 in 2003. Most of the decline is due to a decrease in suicide by hanging and to a lesser extent from motor vehicle carbon monoxide and other gases. Further, the previously established strong secular association (lasting over 3 decades from 1966) between the rate ratio of 20-24 year male suicide to total (crude) male suicide, and the rate ratio of 20-24 year male unemployment to total unemployment, appears to have been disrupted. ARIMA modelling of the suicide ratio against the initiative indicates a highly significant statistical association between the NYSPS and the suicide ratio reduction but not between the NYSPS and the unemployment indicator trend, suggesting a break in the link between young male suicide and unemployment. The recent sudden turnaround in Australian young male suicide trends and its extent appears to preclude explanations centring on slow-moving social indices traditionally associated with suicide, or on possible cohort effects. This sudden decrease

Garrett, R.F.; Boldeman, J.W.

1999-01-01

Full text: The proposed Australian synchrotron light source, Boomerang, is a third generation 3 GeV storage ring which is designed to provide for the great majority of Australian requirements for synchrotron radiation well into the next century. The storage ring could accommodate up to 60 experimental stations, including beamlines from 9 insertion devices, which far exceeds the projected Australian requirements over the life of the facility. Undulator radiation will be available up to 20 keV. The first phase construction of Boomerang includes funding for 9 beamlines, comprising 5 bending magnet and 4 insertion device beamlines. The beamline complement has been chosen to cater for approximately 95% of the current and projected Australian demand for synchrotron radiation over the first 5 years operation of the facility. Details will be shown of the performance of the proposed insertion devices, and the initial beamline complement will be presented

To determine the incidence of and factors associated with vitamin D deficiency rickets in Australian children. 18-month questionnaire-based prospective observational study, using Australian Paediatric Surveillance Unit (APSU) data. Australian paediatricians and child health workers, January 2006 - July 2007. Children aged ≤ 15 years with vitamin D deficiency rickets (25-hydroxyvitamin D [25OHD] ≤ 50 nmol/L, and elevated alkaline phosphatase levels [> 229 IU/L] and/or radiological rickets). Incidence of vitamin D deficiency rickets. Description of demographics, clinical presentation, identification and further analysis of overrepresented groups, and treatment regimens compared with best-practice guidelines. We identified 398 children with vitamin D deficiency (55% male; median age, 6.3 years [range, 0.2-15 years]). The overall incidence in children ≤ 15 years of age in Australia was 4.9/100 000/year. All had a low 25OHD level (median, 28 nmol/L [range, 5-50 nmol]) and an elevated alkaline phosphatase level (median, 407 IU/L [range, 229-5443 IU/L]), and 48 (12%) were hypocalcaemic. Ninety-five children had wrist x-rays, of whom 67 (71%) had rachitic changes. Most (98%) had dark or intermediate skin colour and 18% of girls were partially or completely veiled. Most children were born in Africa (252; 63%) and 75% of children were refugees. Duration of exclusive breastfeeding was inversely related to serum vitamin D levels in children rickets is a significant problem in Australia among known high-risk groups. Public health campaigns to prevent, identify and tre@vitamin D deficiency, especially in high-risk groups, are essential.

Argument for Inclusion of Strongyloidiasis in the Australian National Notifiable Disease List

Directory of Open Access Journals (Sweden)

Meruyert Beknazarova

2018-06-01

Full Text Available Strongyloidiasis is an infection caused by the helminth, Strongyloides stercoralis. Up to 370 million people are infected with the parasite globally, and it has remained endemic in the Indigenous Australian population for many decades. Strongyloidiasis has been also reported in other Australian populations. Ignorance of this disease has caused unnecessary costs to the government health system, and been detrimental to the Australian people’s health. This manuscript addresses the 12 criteria required for a disease to be included in the Australian National Notifiable Disease List (NNDL under the National Health Security Act 2007 (Commonwealth. There are six main arguments that provide compelling justification for strongyloidiasis to be made nationally notifiable and added to the Australian NNDL. These are: The disease is important to Indigenous health, and closing the health inequity gap between Indigenous and non-Indigenous Australians is a priority; a public health response is required to detect cases of strongyloidiasis and to establish the true incidence and prevalence of the disease; there is no alternative national surveillance system to gather data on the disease; there are preventive measures with high efficacy and low side effects; data collection is feasible as cases are definable by microscopy, PCR, or serological diagnostics; and achievement of the Sustainable Development Goal (SDG # 6 on clean water and sanitation.

Using/designing Digital Technologies Of Representation In Aboriginal Australian Knowledge Practices

Directory of Open Access Journals (Sweden)

Helen Verran

2007-01-01

Full Text Available Indigenous Australians are often keen to use digital technologies in their struggle to develop sustainable livelihoods on their own lands. This paper tells of gradually coming to recognize how an Aboriginal Australian elder struggled against the grain of digital technologies designed to represent, in using them in Aboriginal Australian knowledge practices where knowledge is always actively performative rather than representional. The performance of Aboriginal knowledge must express the remaking of an ancestral reality. At the same time, this man exploited possibilities the technologies offered for representation in achieving political ends in dealing with representatives of mainstream Australia.

2013-02-01

Investigation of the social framing of human-shark interactions may provide useful strategies for integrating social, biological, and ecological knowledge into national and international policy discussions about shark conservation. One way to investigate social opinion and forces related to sharks and their conservation is through the media's coverage of sharks. We conducted a content analysis of 300 shark-related articles published in 20 major Australian and U.S. newspapers from 2000 to 2010. Shark attacks were the emphasis of over half the articles analyzed, and shark conservation was the primary topic of 11% of articles. Significantly more Australian articles than U.S. articles treated shark attacks (χ(2) = 3.862; Australian 58% vs. U.S. 47%) and shark conservation issues (χ(2) = 6.856; Australian 15% vs. U.S. 11%) as the primary article topic and used politicians as the primary risk messenger (i.e., primary person or authority sourced in the article) (χ(2) = 7.493; Australian 8% vs. U.S. 1%). However, significantly more U.S. articles than Australian articles discussed sharks as entertainment (e.g., subjects in movies, books, and television; χ(2) = 15.130; U.S. 6% vs. Australian 1%) and used scientists as the primary risk messenger (χ(2) = 5.333; U.S. 25% vs. Australian 15%). Despite evidence that many shark species are at risk of extinction, we found that most media coverage emphasized the risks sharks pose to people. To the extent that media reflects social opinion, our results highlight problems for shark conservation. We suggest that conservation professionals purposefully and frequently engage with the media to highlight the rarity of shark attacks, discuss preventative measures water users can take to reduce their vulnerability to shark encounters, and discuss conservation issues related to local and threatened species of sharks. When integrated with biological and ecological data, social-science data may help generate a more comprehensive perspective

Trends in added sugar supply and consumption in Australia: there is an Australian Paradox

Science.gov (United States)

2013-01-01

In 2011, Barclay and Brand-Miller reported the observation that trends in refined sugar consumption in Australia were the inverse of trends in overweight and obesity (The Australian Paradox). Rikkers et al. claim that the Australian Paradox is based on incomplete data because the sources utilised did not incorporate estimates for imported processed foods. This assertion is incorrect. Indeed, national nutrition surveys, sugar consumption data from the United Nations Food and Agricultural Organisation, the Australian Bureau of Statistics and Australian beverage industry data all incorporated data on imported products.

Self-reported physical health status of Australian Vietnam veterans was determined 20-25 years after the war and its relation to combat was investigated. An epidemiological cohort study of a simple random sample of Army veterans posted to Vietnam between 1964 and 1972 was conducted with personal interviews using the Australian Bureau of Statistics Health Interview Survey questionnaire to compare veterans with the Australian population and a 21-item combat exposure index used to measure the relationship of combat to physical health. Veterans reported greater health service usage and more recent health actions than population expectations. They also reported excess health problems in almost all recent illness disease categories except endocrine conditions and cardiovascular conditions; only 6 of 37 chronic disease groups were not elevated compared to the population. Adjustment for non-response changed estimates only slightly. Combat exposure was significantly related to reports of recent and chronic mental disorders, recent hernia and chronic ulcer, recent eczema and chronic rash, deafness, chronic infective and parasitic disease, chronic back disorders and symptoms, signs and ill-defined conditions. Combat exposure may have significantly increased reports of only some health problems. A general position to complain as a result of psychological conditions due to combat is not consistent with the lack of relationship between combat and reports of physical conditions.

Bertram, William K.

2004-10-01

We present an empirical study of high frequency Australian equity data examining the behaviour of distribution tails and the existence of long memory. A method is presented allowing us to deal with Australian Stock Exchange data by splitting it into two separate data series representing an intraday and overnight component. Power-law exponents for the empirical density functions are estimated and compared with results from other studies. Using the autocorrelation and variance plots we find there to be a strong indication of long-memory type behaviour in the absolute return, volume and transaction frequency.

Dutta, Ritaban; Das, Aruneema; Aryal, Jagannath

2016-02-01

Increasing Australian bush-fire frequencies over the last decade has indicated a major climatic change in coming future. Understanding such climatic change for Australian bush-fire is limited and there is an urgent need of scientific research, which is capable enough to contribute to Australian society. Frequency of bush-fire carries information on spatial, temporal and climatic aspects of bush-fire events and provides contextual information to model various climate data for accurately predicting future bush-fire hot spots. In this study, we develop an ensemble method based on a two-layered machine learning model to establish relationship between fire incidence and climatic data. In a 336 week data trial, we demonstrate that the model provides highly accurate bush-fire incidence hot-spot estimation (91% global accuracy) from the weekly climatic surfaces. Our analysis also indicates that Australian weekly bush-fire frequencies increased by 40% over the last 5 years, particularly during summer months, implicating a serious climatic shift.

When space (time) translation symmetry is spontaneously broken, the space crystal (time crystal) forms; when permittivity and permeability periodically vary with space (time), the photonic crystal (photonic time crystal) forms. We proposed the concept of photonic time crystal and rewritten the Maxwell's equations. Utilizing Finite Difference Time Domain (FDTD) method, we simulated electromagnetic wave propagation in photonic time crystal and photonic space-time crystal, the simulation results show that more intensive scatter fields can obtained in photonic time crystal and photonic space-time crystal.

Large dihydrogen phosphate (KDP) crystals are grown in large crystallizers to provide raw material for the manufacture of optical components for large laser systems. It is a challenge to grow crystal with sufficient mass and geometric properties to allow large optical plates to be cut from them. In addition, KDP has long been the canonical solution crystal for study of growth processes. To assist in the production of the crystals and the understanding of crystal growth phenomena, analysis of growth habits of large KDP crystals has been studied, small scale kinetic experiments have been performed, mass transfer rates in model systems have been measured, and computational-fluid-mechanics tools have been used to develop an engineering model of the crystal growth process. The model has been tested by looking at its ability to simulate the growth of nine KDP boules that all weighed more than 200 kg.

How Australian and Indonesian Universities Treat Plagiarism: A Comparative Study

Directory of Open Access Journals (Sweden)

Bambang Yudi Cahyono

2016-02-01

Full Text Available This article is a part of a larger study comparing various aspects of policies on plagiarism in two university contexts. It compares policies on plagiarism in universities in Australia and Indonesia. The results of this comparative study showed that Australian and Indonesian universities treat plagiarism differently. Australian universities treat plagiarism explicitly in their university policies. In Australian universities, plagiarism is defined clearly and forms of plagiarism are explained thoroughly, policies on plagiarism are informed to all university academic members, and there are mechanisms to manage cases related to plagiarism. In contrast, not all Indonesian universities treat plagiarism directly. Some universities depend on religious morality and academic ethics in dealing with plagiarism. Accordingly, this article recommends the explicit treatment of plagiarism in Indonesian universities.

The breastfeeding behaviors among Australian Defence Force women have not previously been examined. Studies have shown that breastfeeding prevalence and duration are affected by maternity leave entitlements and returning to work. This study aimed to benchmark breastfeeding initiation, prevalence, and duration among a cohort of Australian Defence Force women and to compare these findings against Australian population norms. A cross-sectional survey was conducted via email in 2008 for Australian Defence Force women who had taken maternity leave in the Australian financial year of 2006/2007. Analysis of breastfeeding indicators was undertaken. Ninety-eight percent of Australian Defence Force women in this cohort initiated breastfeeding and breastfed for a median duration of 8 months, returning to work when the mean age of the child was 8.4 months. Breastfeeding prevalence did not meet 2003 Australian National Health and Medical Research Council targets by 6 months postpartum but compared favorably to the Australian population norms. Sixty-six percent of the respondents returned to work full-time, with a median breastfeeding duration of 7 months. Women who returned to work part-time had a longer median duration of 10 months. Breastfeeding rates among this cohort of Australian Defence Force women compare favorably with the general Australian population until 9 months, coinciding with returning to work after a period of maternity leave. The results support recent Australian population studies on breastfeeding and employment. © The Author(s) 2014.

Farming fit? Dispelling the Australian agrarian myth

Directory of Open Access Journals (Sweden)

McCoombe Scott

2011-03-01

Full Text Available Abstract Background Rural Australians face a higher mental health and lifestyle disease burden (obesity, diabetes and cardiovascular disease than their urban counterparts. Our ongoing research reveals that the Australian farming community has even poorer physical and mental health outcomes than rural averages. In particular, farm men and women have high rates of overweightness, obesity, abdominal adiposity, high blood pressure and psychological distress when compared against Australian averages. Within our farming cohort we observed a significant association between psychological distress and obesity, abdominal adiposity and body fat percentage in the farming population. Presentation of hypothesis This paper presents a hypothesis based on preliminary data obtained from an ongoing study that could potentially explain the complex correlation between obesity, psychological distress and physical activity among a farming population. We posit that spasmodic physical activity, changing farm practices and climate variability induce prolonged stress in farmers. This increases systemic cortisol that, in turn, promotes abdominal adiposity and weight gain. Testing the hypothesis The hypothesis will be tested by anthropometric, biochemical and psychological analysis matched against systemic cortisol levels and the physical activity of the subjects. Implications of the hypothesis tested Previous studies indicate that farming populations have elevated rates of psychological distress and high rates of suicide. Australian farmers have recently experienced challenging climatic conditions including prolonged drought, floods and cyclones. Through our interactions and through the media it is not uncommon for farmers to describe the effect of this long-term stress with feelings of 'defeat'. By gaining a greater understanding of the role cortisol and physical activity have on mental and physical health we may positively impact the current rates of psychological

A profession's values guide daily practice and professional behaviours. They clarify what professionalism means to a profession, by providing insight into the values that members of the profession aim to uphold and profess. There has been limited research into the values of the Australian physiotherapy profession, and as such, the values that guide practice and constitute professionalism are not explicit. This study aimed to make a preliminary identification of the values of the profession, by exploring the shared professional values of 14 Australian physiotherapists. This study was guided by a qualitative approach and constructivist paradigm. Purposive sampling was employed to identify physiotherapists who could contribute rich information to the study. Semi-structured interviews were conducted and analysed using an inductive data analysis method. The emerging professional values formed three main themes. The first theme, 'the patient and the patient-therapist partnership', incorporated values such as having patient trust and working collaboratively with patients. The theme labelled 'physiotherapy knowledge, skills and practice' included the values of having an evidence base and respecting professional boundaries. The last theme, 'altruistic values', was inclusive of values such as honesty, empathy and caring. The values that emerged went beyond philanthropic values, to values that guided every day practice, professional relationships and the responsibilities of being a professional. The results contribute to research orientated towards identifying the values of the profession and in doing so, clarifying what professionalism means to the Australian physiotherapy profession. Differences between the values identified by the American Physical Therapy Association and the study reported in this paper highlight the importance of identifying the values of the profession within the Australian context. In terms of practice implications, physiotherapists may be prompted to

Complex networks untangle competitive advantage in Australian football

Braham, Calum; Small, Michael

2018-05-01

We construct player-based complex network models of Australian football teams for the 2014 Australian Football League season; modelling the passes between players as weighted, directed edges. We show that analysis of these measures can give an insight into the underlying structure and strategy of Australian football teams, quantitatively distinguishing different playing styles. The relationships observed between network properties and match outcomes suggest that successful teams exhibit well-connected passing networks with the passes distributed between all 22 players as evenly as possible. Linear regression models of team scores and match margins show significant improvements in R2 and Bayesian information criterion when network measures are added to models that use conventional measures, demonstrating that network analysis measures contain useful, extra information. Several measures, particularly the mean betweenness centrality, are shown to be useful in predicting the outcomes of future matches, suggesting they measure some aspect of the intrinsic strength of teams. In addition, several local centrality measures are shown to be useful in analysing individual players' differing contributions to the team's structure.

Aboriginal Australians represent one of the oldest continuous cultures outside Africa, with evidence indicating that their ancestors arrived in the ancient landmass of Sahul (present-day New Guinea and Australia) ~55 thousand years ago. Genetic studies, though limited, have demonstrated both the uniqueness and antiquity of Aboriginal Australian genomes. We have further resolved known Aboriginal Australian mitochondrial haplogroups and discovered novel indigenous lineages by sequencing the mitogenomes of 127 contemporary Aboriginal Australians. In particular, the more common haplogroups observed in our dataset included M42a, M42c, S, P5 and P12, followed by rarer haplogroups M15, M16, N13, O, P3, P6 and P8. We propose some major phylogenetic rearrangements, such as in haplogroup P where we delinked P4a and P4b and redefined them as P4 (New Guinean) and P11 (Australian), respectively. Haplogroup P2b was identified as a novel clade potentially restricted to Torres Strait Islanders. Nearly all Aboriginal Australian mitochondrial haplogroups detected appear to be ancient, with no evidence of later introgression during the Holocene. Our findings greatly increase knowledge about the geographic distribution and phylogenetic structure of mitochondrial lineages that have survived in contemporary descendants of Australia’s first settlers.

Homogenised Australian climate datasets used for climate change monitoring

Full text: The Australian Bureau of Meteorology has developed a number of datasets for use in climate change monitoring. These datasets typically cover 50-200 stations distributed as evenly as possible over the Australian continent, and have been subject to detailed quality control and homogenisation.The time period over which data are available for each element is largely determined by the availability of data in digital form. Whilst nearly all Australian monthly and daily precipitation data have been digitised, a significant quantity of pre-1957 data (for temperature and evaporation) or pre-1987 data (for some other elements) remains to be digitised, and is not currently available for use in the climate change monitoring datasets. In the case of temperature and evaporation, the start date of the datasets is also determined by major changes in instruments or observing practices for which no adjustment is feasible at the present time. The datasets currently available cover: Monthly and daily precipitation (most stations commence 1915 or earlier, with many extending back to the late 19th century, and a few to the mid-19th century); Annual temperature (commences 1910); Daily temperature (commences 1910, with limited station coverage pre-1957); Twice-daily dewpoint/relative humidity (commences 1957); Monthly pan evaporation (commences 1970); Cloud amount (commences 1957) (Jovanovic etal. 2007). As well as the station-based datasets listed above, an additional dataset being developed for use in climate change monitoring (and other applications) covers tropical cyclones in the Australian region. This is described in more detail in Trewin (2007). The datasets already developed are used in analyses of observed climate change, which are available through the Australian Bureau of Meteorology website (http://www.bom.gov.au/silo/products/cli_chg/). They are also used as a basis for routine climate monitoring, and in the datasets used for the development of seasonal

Full Text Available Abstract Background Obesity and related cardiovascular and metabolic conditions are well recognized problems for Australian Aboriginal and Torres Strait Islander peoples. However, there is a dearth of research on relevant eating disorders (EDs such as binge eating disorder in these groups. Methods Data were obtained from interviews of 3047 (in 2005 and 3034 (in 2008 adults who were participants in a randomly selected South Australian household survey of individuals' age > 15 years. The interviewed comprised a general health survey in which ED questions were embedded. Data were weighted according to national census results and comprised key features of ED symptoms. Results In 2005 there were 94 (85 weighted First Australian respondents, and in 2008 65 (70 weighted. Controlling for secular differences, in 2005 rates of objective binge eating and levels of weight and shape influence on self-evaluation were significantly higher in indigenous compared to non-indigenous participants, but no significant differences were found in ED features in 2008. Conclusions Whilst results on small numbers must be interpreted with caution, the main finding was consistent over the two samples. For First Australians ED symptoms are at least as frequent as for non-indigenous Australians.

Australian researchers have access to a variety of natural systems where records of the Earth's past environment have been stored. These archives include sediment cores, Antarctic ice, Tasmanian pine trees, rock surfaces, corals, etc. Each of these media contain information on past environmental conditions but the records must be carefully deciphered and compared with one-another. The AMS analysis of long-lived cosmogenic radionuclides is essential for providing absolute time scales for these natural archives. Other analytical methods based on high-energy ion interactions are well suited to characterise environmental and archaeological samples with high sensitivity. The use of ANSTO's accelerators in research programs related to the environment in the Australian region is reviewed

2014-12-01

Full Text Available Despite a significant increase in enrolments of postgraduate international Muslim students within Australian universities, little is known about their perceptions of life within Australian homes while undertaking their studies. The aim of this study is to investigate the ways in which students’ cultural and religious traditions affect their use of domestic spaces within the homes in which they reside. The research found that participants faced some minor difficulties in achieving privacy, maintaining modesty and extending hospitality while able to perform their daily activities in Australian designed homes. The findings suggest that greater research attention needs to be given to the development of Australian home designs that are adaptable to the needs of a multicultural society. Australian society encompasses diverse cultural customs and requirements with respect to home design, and these are yet to be explored.

This study aims to evaluate the effectiveness of the Multisystemic Therapy (MST) intervention for Australian families invloved with the Specialist Child and Adolescent Mental Health Service (CAMHS). This program was implemented within the Western Australian Department of Health in 2005, and has continually operated two small clinical teams within the Perth metropolitan area since then. This intervention was specifically chosen to improve service access, engagement, and intervention with vulnerable families having young persons with a history of significant and enduring behavioural problems. The study reports on data collected from July 2007 to July 2013 which includes baseline, post-treatment, 6-month, and 12-month follow-up. There were 153 MST families participating in the research at all time points (71% male; 11% Australian Aboriginal; average youth age was 13.6 years). Caregivers completed a set of questionnaires including Child Behaviour Checklist, Parenting Styles and Dimensions Questionnaire, and Depression, Anxiety and Stress Scale. One-way repeated measure ANOVA were used to measure changes over time. Significant caregiver-reported improvements in all measures were reported at post-treatment, and most improvements were maintained at the follow-up periods of 6 and 12 months post-intervention. These preliminary outcomes demonstrate that the 4-5 month MST intervention significantly reduces behavioural problems and emotional difficulties in young Australians and these improvements are generally maintained by caregivers over time. Primary caregivers reported improved skills and mental health functioning that were also maintained over the follow-up period. A proposed randomised controlled trial of the program will address potential placebo and selection bias effects.

We succeeded in the crystallization of d(CGCGCG) 2 and methylamine Complex. The crystal was clear and of sufficient size to collect the X-ray crystallographic data up to 1.0 A resolution using synchrotron radiation. As a result of X-ray crystallographic analysis of 2F o - F c map was much clear and easily traced. It is First time monoamine co-crystallizes with d(CGCGCG) 2 . However, methylamine was not found from the complex crystal of d(CGCGCG) 2 and methylamine. Five Mg ions were found around d(CGCGCG) 2 molecules. These Mg ions neutralized the anion of 10 values of the phosphate group of DNA with five Mg 2+ . DNA stabilized only by a metallic ion and there is no example of analyzing the X-ray crystal structure like this. Mg ion stabilizes the conformation of Z-DNA. To use monoamine for crystallization of DNA, we found that we can get only d(CGCGCG) 2 and Mg cation crystal. Only Mg cation can stabilize the conformation of Z-DNA. The method of using the monoamine for the crystallization of DNA can be applied to the crystallization of DNA of long chain of length in the future like this

Mental illnesses constitute a major burden of disease in Aboriginal Australians and Torres Strait Islanders (hereafter Aboriginal Australians), who are also overrepresented in the prison system. A legacy of colonization compounds such prevalence, and is further exacerbated by the persistence of racial discrimination and insensitivity across many sectors, including health. This research completed in a Western Australian forensic mental health setting identifies non-Aboriginal health professionals' support needs to deliver high-quality, culturally-safe care to Aboriginal patients. Data were collected from health professionals using an online survey and 10 semistructured interviews. Survey and interview results found that ongoing education was needed for staff to provide culturally-safe care, where Aboriginal knowledge, beliefs, and values were respected. The findings also support previous research linking Aboriginal health providers to improved health outcomes for Aboriginal patients. In a colonized country, such as Australia, education programmes that critically reflect on power relations privileging white Anglo-Australian cultural dominance and subjugating Aboriginal knowledge, beliefs, and values are important to identify factors promoting or compromising the care of Aboriginal patients and developing a deeper understanding of 'cultural safety' and its clinical application. Organizational commitment is needed to translate the findings to support non-Aboriginal health professionals deliver high-quality care to Aboriginal patients that is respectful of cultural differences. © 2013 Australian College of Mental Health Nurses Inc.

Boufous, Soufiane; Aboss, Ahmad; Montgomery, Victoria

2016-10-01

To assess information on cyclist crashes reported in Australian newspapers. The Factiva news archive was searched for articles on cyclist crashes published in major Australian newspapers between 2010 and 2013. Information on the circumstances of cyclist crashes were extracted and coded. A total of 160 cyclist crashes were covered by 198 newspaper articles, with 44% of crashes resulting in cyclist fatalities. Crashes reported by more than one newspaper were more likely to involve public figures or protracted court cases. Individual characteristics of cyclists as well as the location of the crash were reported for more than 80% of crashes. The road user at fault was reported for more than half of crashes. In contrast, information on helmet use, alcohol and cycling lanes was mentioned for only about 10% of crashes. Fewer than one in five articles mentioned prevention strategies including education campaigns, legislative and infrastructure changes. Australian newspapers tend to focus on the most dramatic and more 'newsworthy' aspects of cyclist crashes. Cycling advocates need to work with journalists to improve the quality of this coverage. Better communication between cycling advocates and journalists is likely to have a positive impact on the safety and the uptake of cycling in the community. © 2016 Public Health Association of Australia.

Fragranced consumer products: effects on asthmatic Australians.

Steinemann, Anne; Wheeler, Amanda J; Larcombe, Alexander

2018-01-01

Exposure to fragranced consumer products, such as air fresheners and cleaning supplies, is associated with adverse health effects such as asthma attacks, breathing difficulties, and migraine headaches. This study investigated the prevalence and types of health problems associated with exposure to fragranced products among asthmatic Australians. Nationally representative cross-sectional data were obtained in June 2016 with an online survey of adult Australians ( n  = 1098), of which 28.5% were medically diagnosed with asthma or an asthma-like condition. Nationally, 55.6% of asthmatics, and 23.9% of non-asthmatics, report adverse health effects after exposure to fragranced products. Specifically, 24.0% of asthmatics report an asthma attack. Moreover, 18.2% of asthmatics lost workdays or a job in the past year due to fragranced products in the workplace. Over 20% of asthmatics are unable to access public places and restrooms that use air fresheners. Exposure to fragranced products is associated with health problems, some potentially serious, in an estimated 2.2 million asthmatic adult Australians. Asthmatics were proportionately more affected than non-asthmatics (prevalence odds ratio 3.98; 95% confidence interval 3.01-5.24). Most asthmatics would prefer workplaces, healthcare facilities, and environments that are fragrance-free, which could help reduce adverse effects.

Feeding and development of the glassy-winged sharpshooter, Homalodisca vitripennis, on Australian native plant species and implications for Australian biosecurity.

Directory of Open Access Journals (Sweden)

Anna A Rathé

Full Text Available In any insect invasion the presence or absence of suitable food and oviposition hosts in the invaded range is a key factor determining establishment success. The glassy-winged sharpshooter, Homalodisca vitripennis, is an important insect vector of the xylem-limited bacterial plant pathogen, Xylella fastidiosa, which causes disease in numerous host plants including food and feedstock crops, ornamentals and weeds. Both the pathogen and the vector are native to the Americas and are considered to be highly invasive. Neither has been detected in Australia. Twelve Australian native plant species present in the USA were observed over two years for suitability as H. vitripennis feeding, oviposition and nymph development hosts. Hosts providing evidence of adult or nymph presence were Leptospermum laevigatum, Acacia cowleana, Eremophila divaricata, Eucalyptus wandoo, Hakea laurina, Melaleuca laterita and Swainsona galegifolia. An oviposition-suitability field study was conducted with citrus, a favoured oviposition host, as a positive control. Citrus and L. laevigatum, A. cowleana, B. ericifolia×B. spinulosa, C. pulchella, E. divaricata, E. wandoo, H. laurina, and S. galegifolia were found to be oviposition hosts. Egg parasitism by the mymarid parasitoid Gonatocerus ashmeadi was observed on all Australian plants. A number of Australian plants that may facilitate H. vitripennis invasion have been identified and categorised as 'high risk' due to their ability to support all three life stages (egg, nymph and adult of the insect in the field (L. laevigatum, A. cowleana, E. divaricata, H. laurina, and S. galegifolia. The implications of these host status and natural enemy research findings are discussed and placed in an Australian invasion context.

A national-wide survey of radon and gamma radiation levels in Australian homes

International Nuclear Information System (INIS)

Langaroo, M.K.; Wise, K.N.; Duggleby, J.K.; Kotler, L.H.

1990-04-01

A nation-wide survey of Australian homes has been conducted to determine the average annual doses to the Australian population from exposure to radon and gamma radiation. The exposure to radon was measured using solid state track detectors (SSTD) whilst the gamma radiation dose was concurrently determined using thermoluminescent dosimetry. Dosemeters were placed in approximately 3400 randomly distributed homes (representing about 1 in 1400 occupied dwellings) for twelve months. The measured annual average radon concentration in Australian homes is 12 Bq m -3 . Using appropriate conversion factors, the annual average effective dose equivalents to the Australian population were determined to be 0.6 mSv and 0.9 mSv for radon and gamma radiation respectively. 20 refs., 3 tabs., 7 figs

Sayakhot, Padaphet; Vincent, Amanda; Teede, Helena

2012-12-01

The aim of this study was to investigate and compare symptom experiences, beliefs, attitudes, and understanding of menopause and menopausal therapies in Australian and Laotian women. This was a cross-cultural, questionnaire-based study involving 108 women (56 Australian women and 52 Laotian women aged 40-65 y) attending outpatient clinics in Australia and Laos. Descriptive statistics and univariate analysis were conducted using Student's t test or Mann-Whitney U test, where appropriate. Psychological symptoms, depression, vasomotor symptoms, and sexual dysfunction were significantly higher in Australian women compared with Laotian women (P menopause as aging (57%), whereas most Laotian women reported not knowing what menopause meant to them (81%). Australian women's fears about menopause included weight gain (43%), aging (41%), and breast cancer (38%), whereas Laotian women reported not knowing about potential menopausal problems (85%). Exercise (55%), education and awareness (46%), and improving lifestyle (41%) were reported by Australian women as being effective in alleviating menopausal symptoms, with only 21% reporting not knowing what was effective compared with 83% of Laotian women. Many women reported not knowing the risks/benefits of hormonal therapies (50% of Australian women and 87% of Laotian women) and herbal therapies (79% of Australian women and 92% of Laotian women). General practitioners were the most common source of menopause information for both Australians (73%) and Laotians (67%). Sociocultural factors influence women's perception of menopause. Psychological symptoms, sexual dysfunction, and vasomotor symptoms are more commonly reported by Australian women than by Laotian women. Women have a limited understanding of the risks/benefits of menopausal therapies, and culturally appropriate education is needed.

Mohini Singh

2004-11-01

Full Text Available This paper discusses e-business developmental issues in the Australian Food industry that were identified from a research project funded by the Australian Research Council. Data was gathered from interviews with 11 food organisations in the year 2000, most of which can be classified as ‘bricks and clicks’. These 11 companies were traditional businesses that had adopted e-business as a new way of doing business. The findings of the paper highlight the fact that the B2B is the predominant e-business model in the Australian Food Industry, EDI is an important foundation technology platform for developing B2B e-business, e-procurement was an important reason for adopting B2B e-business and improved supply chain management was the most important achievement from E-Business for these organizations. It also highlighted the fact e-business developed in-house with an IT department managed e-business sites better than those that outsourced the development.

The outlook for the world and Australian oil markets

International Nuclear Information System (INIS)

Donaldson, K.; Fok, G.

1996-01-01

Global demand for oil is projected to continue its upward trend to 2000-1, with growth in the transport sector expected to underpin future increases in oil consumption. World oil consumption is projected to be matched by global production, keeping the average annual oil price relatively stable. In many countries, the diversion of oil revenue to other projects is threatening to constrain increases in production capacity, particularly in the OPEC countries. The encouragement of foreign investment in state oil industries is a likely method of easing the constraint. Australian exploration activity is rising steadily with the prospect of stable oil prices, expanding gas markets and the incentives provided by a number of recent discoveries. While the geographical pattern of Australian production has now changed, with Western Australian production exceeding Victoria production, Australia is expected to maintain its position in the world oil market as a significant producer, importer and exporter.

Blee, Alisa J; Walshe, Keryn; Pring, Allan; Quinton, Jamie S; Lenehan, Claire E

2010-07-15

There is limited information regarding the nature of plant and animal residues used as adhesives, fixatives and pigments found on Australian Aboriginal artefacts. This paper reports the use of FTIR in combination with the chemometric tools principal component analysis (PCA) and hierarchical clustering (HC) for the analysis and identification of Australian plant and animal fixatives on Australian stone artefacts. Ten different plant and animal residues were able to be discriminated from each other at a species level by combining FTIR spectroscopy with the chemometric data analysis methods, principal component analysis (PCA) and hierarchical clustering (HC). Application of this method to residues from three broken stone knives from the collections of the South Australian Museum indicated that two of the handles of knives were likely to have contained beeswax as the fixative whilst Spinifex resin was the probable binder on the third.

Gauging Change in Australian Aid: Stakeholder Perceptions of the Government Aid Program.

Science.gov (United States)

Wood, Terence; Burkot, Camilla; Howes, Stephen

2017-05-01

In this article, we use data from the 2013 and 2015 Australian Aid Stakeholder Surveys to gauge the extent of the changes to the Australian Government Aid Program since the 2013 federal election. The two surveys targeted the same set of stakeholders of the aid program, and both gathered data on a wide range of aspects of its functioning. As we assess the findings that emerged from the surveys, we situate our work amongst recent academic studies that have looked at the post-2013 aid changes in Australia. Our key findings are that the post-2013 changes to Australian aid have had wide-ranging impacts and have led to deteriorating overall aid quality. However, changes have not affected all aspects of the aid program equally, and some changes are starting to be reversed. In discussion, we examine what these developments mean for the future of Australian aid.

The politics of accountability for school curriculum: An Australian case study

Science.gov (United States)

Smithson, Alan

1987-03-01

This normative-descriptive case study of accountability for state school curriculum in South Australia has the following objectives. First, to seek to draw a distinction between accountability and responsibility: terms which have been confused by two South Australian Directors-General of Education (position akin to C.E.O. in the U.K. and Superintendent in the U.S.A.) with important consequences. Second, to present a model of accountability for state school curriculum, by which accountability for such curriculum may be judged democratic or non-democratic, and against which accountability for curriculum in South Australian state schools will be gauged. Third, to show that whilst the South Australian school system exhibits a large measure of bureaucratic or technocratic accountability for curriculum, there is no effective democratic accountability for curriculum, and to indicate a remedy for this situation. Finally, to point out the wider significance of the South Australian case study, and suggest that democracies currently re-structuring their educational systems would do well to keep the need for democratic accountability foremost in mind.

Testing the Australian Megatsunami Hypothesis

Courtney, Claire; Strotz, Luke; Chague-Goff, Catherine; Goff, James; Dominey-Howes, Dale

2010-05-01

In the wake of the 2004 Indian Ocean Tsunami, many countries have been forced to reassess the risk of tsunamis to their coasts. Australia, with relative tectonic stability, has previously been considered at low risk of tsunami inundation. Within written history, only small tsunamis have struck the Australian coast, causing little damage. However, a body of work has arisen that sheds doubt on this apparent low risk, with researchers suggesting that megatsunamis have affected the east Australian coast, in particular southern New South Wales. With proposed run-ups in excess of 100m, recurrence of such megatsunamis in the now densely populated New South Wales coastal region would be catastrophic. The disjunct between historical and geological records demands a thorough re-evaluation of New South Wales sites purported to contain evidence of megatsunamis. In addition, the unique set of diagnostic criteria previously used to identify Australian palaeotsunami deposits is distinctly different to criteria applied to paleotsunamis globally. To address these issues, four coastal lagoonal sites in southern New South Wales were identified for further investigation. In addition to paleotsunami investigation, these sites were selected to provide a geological record of significant events during the Holocene. Site selection was based on small accommodation space and a high preservation potential with back barrier depressions closed to the sea. A suite of diagnostic criteria developed over the past two decades to identify palaeotsunamis have been applied to cores extracted from these sites. Methods used include sedimentary description, grain size analysis, micropalaeontology, geochemistry and a variety of dating techniques such as radiocarbon and lead 210. Preliminary analysis of these results will be presented, with particular focus on sites where there is evidence that could indicate catastrophic saltwater inundation.

The origins and radiation of Australian Coptotermes termites: from rainforest to desert dwellers.

Science.gov (United States)

Lee, Timothy R C; Cameron, Stephen L; Evans, Theodore A; Ho, Simon Y W; Lo, Nathan

2015-01-01

The termite genus Coptotermes (Rhinotermitidae) is found in Asia, Africa, Central/South America and Australia, with greatest diversity in Asia. Some Coptotermes species are amongst the world's most damaging invasive termites, but the genus is also significant for containing the most sophisticated mound-building termites outside the family Termitidae. These mound-building Coptotermes occur only in Australia. Despite its economic and evolutionary significance, the biogeographic history of the genus has not been well investigated, nor has the evolution of the Australian mound-building species. We present here the first phylogeny of the Australian Coptotermes to include representatives from all described species. We combined our new data with previously generated data to estimate the first phylogeny to include representatives from all continents where the genus is found. We also present the first estimation of divergence dates during the evolution of the genus. We found the Australian Coptotermes to be monophyletic and most closely related to the Asian Coptotermes, with considerable genetic diversity in some Australian taxa possibly representing undescribed species. The Australian mound-building species did not form a monophyletic clade. Our ancestral state reconstruction analysis indicated that the ancestral Australian Coptotermes was likely to have been a tree nester, and that mound-building behaviour has arisen multiple times. The Australian Coptotermes were found to have diversified ∼13million years ago, which plausibly matches with the narrowing of the Arafura Sea allowing Asian taxa to cross into Australia. The first diverging Coptotermes group was found to be African, casting doubt on the previously raised hypothesis that the genus has an Asian origin. Copyright © 2014 Elsevier Inc.

Kerin, J.C.

1988-01-01

The Australian Government considers that allegations made by the West German magazine - Der Spiegel in its January and February 1988 editions, flow from a lack of understanding of the complexities of international trade in nuclear materials, confusion between internal and international flag swaps and failure to comprehend the equivalence principle used in nuclear materials accounting. The Ministerial statement briefly outlines these issues and concludes that there is no evidence that any material subject to Australia's bilateral safeguards agreement has been diverted from peaceful uses or that Australia's safeguard requirements have been breached

Australian methane fluxes

Williams, D.J.

1990-01-01

Estimates are provided for the amount of methane emitted annually into the atmosphere in Australia for a variety of sources. The sources considered are coal mining, landfill, motor vehicles, natural gas suply system, rice paddies, bushfires, termites, wetland and animals. This assessment indicates that the major sources of methane are natural or agricultural in nature and therefore offer little scope for reduction. Nevertheless the remainder are not trival and reduction of these fluxes could play a significant part in any Australian action on the greenhouse problem. 19 refs., 7 tabs., 1 fig

Principles of crystallization, and methods of single crystal growth

International Nuclear Information System (INIS)

Chacra, T.

2010-01-01

Most of single crystals (monocrystals), have distinguished optical, electrical, or magnetic properties, which make from single crystals, key elements in most of technical modern devices, as they may be used as lenses, Prisms, or grating sin optical devises, or Filters in X-Ray and spectrographic devices, or conductors and semiconductors in electronic, and computer industries. Furthermore, Single crystals are used in transducer devices. Moreover, they are indispensable elements in Laser and Maser emission technology.Crystal Growth Technology (CGT), has started, and developed in the international Universities and scientific institutions, aiming at some of single crystals, which may have significant properties and industrial applications, that can attract the attention of international crystal growth centers, to adopt the industrial production and marketing of such crystals. Unfortunately, Arab universities generally, and Syrian universities specifically, do not give even the minimum interest, to this field of Science.The purpose of this work is to attract the attention of Crystallographers, Physicists and Chemists in the Arab universities and research centers to the importance of crystal growth, and to work on, in the first stage to establish simple, uncomplicated laboratories for the growth of single crystal. Such laboratories can be supplied with equipment, which are partly available or can be manufactured in the local market. Many references (Articles, Papers, Diagrams, etc..) has been studied, to conclude the most important theoretical principles of Phase transitions,especially of crystallization. The conclusions of this study, are summarized in three Principles; Thermodynamic-, Morphologic-, and Kinetic-Principles. The study is completed by a brief description of the main single crystal growth methods with sketches, of equipment used in each method, which can be considered as primary designs for the equipment, of a new crystal growth laboratory.

Learner discipline: An Australian perspective

Directory of Open Access Journals (Sweden)

D. Stewart

2004-07-01

Full Text Available Australian schools by and large are safe schools. Nonetheless discipline problems do exist – including bullying behaviour. For this kind of problem schools should have management policies in place. As traditional behaviour-management practices – including corporal punishment – are largely prohibited in Australian schools, contemporary practices centre on management through supportive school programmes, including appropriate curricula and school-support structures. This article supports the belief that measures such as the exclusion of misbehaving learners should be treated with caution. Measures such as this might not reflect accepted international principles and practices and should only be exercised in the most extreme circumstances. The article also supports the view that it is part of the school’s role to ensure that all learners are aware of the reality that while they have rights, they also have corresponding responsibilities. This awareness is more likely to be achieved in a supportive school culture where each learner is recognised as having unique qualities that can mature and grow in an appropriate learning environment.

Australian bat lyssavirus: implications for public health.

Science.gov (United States)

Francis, Joshua R; McCall, Bradley J; Hutchinson, Penny; Powell, Jodie; Vaska, Vikram L; Nourse, Clare

2014-12-11

Australian bat lyssavirus (ABLV) infection in humans is rare but fatal, with no proven effective therapy. ABLV infection can be prevented by administration of a post-exposure prophylaxis regimen of human rabies immunoglobulin and rabies vaccine. All Australian bats (flying foxes and microbats) should be considered to be carrying ABLV unless proven otherwise. Any bat-related injury (bite, scratch or mucosal exposure to bat saliva or neural tissue) should be notified immediately to the relevant public health unit - no matter how small the injury or how long ago it occurred. Human-to-human transmission of ABLV has not been reported but is theoretically possible. Standard infection control precautions should be employed when managing patients with suspected or confirmed ABLV infection.

Are Australian immigrants at a risk of being physically inactive?

Directory of Open Access Journals (Sweden)

Gurrin Lyle

2011-06-01

Full Text Available Abstract Background We examined whether physical activity risk differed between migrant sub-groups and the Australian-born population. Methods Data were drawn from the Australian National Health Survey (2001 and each resident's country of birth was classified into one of 13 regions. Data were gathered on each resident's physical activity level in the fortnight preceding the survey. Multivariable logistic regression, adjusted for potential confounders examined the risk of physical inactivity of participants from each of the 13 regions compared to the Australian-born population. Results There was a greater prevalence of physical inactivity for female immigrants from most regions compared to male immigrants from a like region. Immigrants from South East Asia (OR 2.04% 95% CI 1.63, 2.56, Other Asia (OR 1.53 95% CI 1.10, 2.13, Other Oceania (1.81 95% CI 1.11, 2.95, the Middle East (OR 1.42 95% CI 0.97, 2.06 [note: border line significance] and Southern & Eastern Europe are at a significantly higher risk of being physically inactive compared to those born in Australian. In contrast, immigrants from New Zealand (OR 0.77 95% CI 0.62, 0.94, the UK & Ireland (OR 0.82 95% CI 0.73, 0.92, and other Africa (OR 0.69 95% CI 0.51, 0.94 are at a significantly lower risk of being physically inactive compared to the Australian born population. Conclusion Future research identifying potential barriers and facilitators to participation in physical activity will inform culturally sensitive physical activity programs that aim to encourage members of specific regional ethnic sub-groups to undertake physical activity.

This study sought to determine the construct validity of two self-report measures of attitudes towards Aboriginal Australians and Torres Strait Islanders against an implicit measure of attitude. Total of 102 volunteer participants completed the three measures in a randomized order. The explicit measures of prejudice towards Aboriginal Australians were the Modern Racism Scale (MRS) and the Attitudes Towards Indigenous Australians Scale (ATIAS). The implicit attitudes measure was an adaptation of the Implicit Association Test (IAT) and utilised simple drawn head-and-shoulder images of Aboriginal Australians and White Australians as the stimuli. Both explicit measures and implicit measure varied in the extent to which negative prejudicial attitudes were held by participants, and the corresponding construct validities were unimpressive. The MRS was significantly correlated with the IAT, (r =.314;pAboriginal Australians, only the MRS evidenced validity when compared with the use of an implicit attitude measure.

To simultaneously quantify and profile the complex mixture of short-, median-, and long-chain CPs (SCCPs, MCCPs, and LCCPs) in Australian sewage sludge, we applied and further validated a recently developed novel instrumental technique, using quadrupole time-of-flight high resolution mass spectrometry running in the negative atmospheric pressure chemical ionization mode (APCI-qTOF-HRMS). Without using an analytical column the cleaned extracts were directly injected into the qTOF-HRMS followed by quantification of the CPs by a mathematical algorithm. The recoveries of the four SCCP, MCCP and LCCP-spiked sewage sludge samples ranged from 86 to 123%. This APCI-qTOF-HRMS method is a fast and promising technique for routinely measuring SCCPs, MCCPs, and LCCPs in sewage sludge. Australian sewage sludge was dominated by MCCPs with concentrations ranging from 542 to 3645 ng/g dry weight (dw). Lower SCCPs concentrations (<57-1421 ng/g dw) were detected in the Australian sewage sludge, which were comparable with the LCCPs concentrations (116-960 ng/g dw). This is the first time that CPs were reported in Australian sewage sludge. The results of this study gives a first impression on the distribution of the SCCPs, MCCPs, and LCCPs in Australia wastewater treatment plants (WWTPs).

Quadramet T (Samarium-153 EDTMP) has been shown overseas to be potentially useful in the palliation of painful osteoblastic skeletal metastases and has been approved this year for general marketing in the USA. Australian Radioisotopes (ARI) has licensed this product from the Australian patent holders, Dow Chemical. Within the facilities of ARI, a hot cell has been dedicated to this product and fitted out to manufacture it weekly on a cycle related to the operating cycle of the Australian reactor HIFAR. Due to neutron flux limitations of HIFAR, the local formulation has an elemental Samarium content up to 200μg/mL whereas the overseas formulation has a level of 20-46μg/mL. All other specifications of the two products are essentially the same. In 1995 and 1996 a small clinical trial with 19 patients was held which demonstrated that the pharmacokinetic behaviour was also essentially the same by measuring blood clearance rates and skeletal uptake dynamics. Soft tissue uptake was also qualitatively determined. The ARI version is now the subject of an application for general marketing within Australia. Some useful characteristics of this agent are: almost complete excretion or fixation in the skeleton within 6 hours, rapid onset of clinical effect, applicability in most cases where an abnormal diagnostic bone scan correlates with painful sites, dosage can be tailored to individual patient uptake due to easy dose measurement and retreatment is quite possible. The use of this class of agents in pain palliation continues to increase. Australian manufacture of Quadramet TM provides a further option in the management of these difficult cases

Marfan syndrome may affect the cardiovascular, ocular and skeletal systems. The gene for this autosomal dominant disease maps to chromosome 15 and codes for the extracellular matrix protein fibrillin. Phenotypic expression is very variable both within and between families, possibly due to the influence of other, unlinked, genetic factors interacting with the fibrillin gene. We report two Australian families which demonstrate the extent of inter- and intra-family phenotypic variability. Eye, cardiac and skeletal assessments were made independently. In the first family, 8 of 12 siblings and 11 of 19 of their children had ectopia lentis with or without other ocular findings. There were few cardiac signs. One child had mitral valve prolapse. He and three other children had mild dilatation of the aorta. Skeletal abnormalities were also found (3 adults and 7 children). Chest wall asymmetry was the most common skeletal finding. This family has less cardiac and skeletal involvement than is usual in Marfan syndrome, although the disease maps to chromosome 15 in the region of the fibrillin gene (LOD=4.8 at {theta}=0 with respect to CYP19). The second family is partly of Australian aboriginal origin. The disease has been traced through 5 generations. To date we have examined 37 of 84 living members. Twenty-three in 3 generations are affected. Five adults and 4 children have moderate to severe aortic dilatation and there has been at least one death due to aortic dissection. However, two adolescents with subluxed lenses and marked skeletal abnormalities have normal aortic diameters, two children have aortic dilatation without other signs and two children have only subluxed lenses. This family shows the range of phenotypic variation which can arise from mutation in the fibrillin gene, which may be influenced by the admixture of Australian aboriginal genes. These two families provide an invaluable resource for studying genetic interactions in this disease.

We present an Aboriginal Australian genomic sequence obtained from a 100-year-old lock of hair donated by an Aboriginal man from southern Western Australia in the early 20th century. We detect no evidence of European admixture and estimate contamination levels to be below 0.5%. We show that Aboriginal Australians are descendants of an early human dispersal into eastern Asia, possibly 62,000 to 75,000 years ago. This dispersal is separate from the one that gave rise to modern Asians 25,000 to 38,000 years ago. We also find evidence of gene flow between populations of the two dispersal waves prior to the divergence of Native Americans from modern Asian ancestors. Our findings support the hypothesis that present-day Aboriginal Australians descend from the earliest humans to occupy Australia, likely representing one of the oldest continuous populations outside Africa.

The handball pass is influential in Australian football, and achieving higher ball speeds in flight is an advantage in increasing distance and reducing the chance of interceptions. The purpose of this study was to provide descriptive kinematic data and identify key technical aspects of maximal handball performance. Three-dimensional full body kinematic data from 19 professional Australian football players performing handball pass for maximal speed were collected, and the hand speed at ball contact was used to determine performance. Sixty-four kinematic parameters initially obtained were reduced to 15, and then grouped into like components through a two-stage supervised principal components analysis procedure. These components were then entered into a multiple regression analysis, which indicated that greater hand speed was associated with greater shoulder angular velocity and separation angle between the shoulders and pelvis at ball contact, as well as an earlier time of maximum upper-trunk rotation velocity. These data suggested that in order to increase the speed of the handball pass in Australian football, strategies like increased shoulder angular velocity, increased separation angle at ball contact, and earlier achievement of upper-trunk rotation speed might be beneficial.

Dawes Review 5: Australian Aboriginal Astronomy and Navigation

Science.gov (United States)

Norris, Ray P.

2016-08-01

The traditional cultures of Aboriginal Australians include a significant astronomical component, perpetuated through oral tradition, ceremony, and art. This astronomical knowledge includes a deep understanding of the motion of objects in the sky, which was used for practical purposes such as constructing calendars and for navigation. There is also evidence that traditional Aboriginal Australians made careful records and measurements of cyclical phenomena, recorded unexpected phenomena such as eclipses and meteorite impacts, and could determine the cardinal points to an accuracy of a few degrees. Putative explanations of celestial phenomena appear throughout the oral record, suggesting traditional Aboriginal Australians sought to understand the natural world around them, in the same way as modern scientists, but within their own cultural context. There is also a growing body of evidence for sophisticated navigational skills, including the use of astronomically based songlines. Songlines are effectively oral maps of the landscape, and are an efficient way of transmitting oral navigational skills in cultures that do not have a written language. The study of Aboriginal astronomy has had an impact extending beyond mere academic curiosity, facilitating cross-cultural understanding, demonstrating the intimate links between science and culture, and helping students to engage with science.

Savanna ecosystems comprise 22% of the global terrestrial surface and 25% of Australia (almost 1.9 million km2) and provide significant ecosystem services through carbon and water cycles and the maintenance of biodiversity. The current structure, composition and distribution of Australian savannas have coevolved with fire, yet remain driven by the dynamic constraints of their bioclimatic niche. Fire in Australian savannas influences both the biophysical and biogeochemical processes at multiple scales from leaf to landscape. Here, we present the latest emission estimates from Australian savanna biomass burning and their contribution to global greenhouse gas budgets. We then review our understanding of the impacts of fire on ecosystem function and local surface water and heat balances, which in turn influence regional climate. We show how savanna fires are coupled to the global climate through the carbon cycle and fire regimes. We present new research that climate change is likely to alter the structure and function of savannas through shifts in moisture availability and increases in atmospheric carbon dioxide, in turn altering fire regimes with further feedbacks to climate. We explore opportunities to reduce net greenhouse gas emissions from savanna ecosystems through changes in savanna fire management. PMID:25044767

Are we there yet? Travel vaccinations for Australian children.

Slonim, Marnie; Starr, Mike; Blashki, Grant

2014-06-01

Australians travel overseas frequently and general practitioners (GPs) are often asked to provide detailed advice on travel vaccinations for children. Planning a safe and effective vaccination schedule is dependent on the context: where and when the family is travelling, the individual child's medical needs and past vaccination history, and if they are visiting family and friends. In this paper we provide an overview of the issues to consider when vaccinating Australian children for overseas travel. We also list the suite of common travel vaccinations and discuss some clinical scenarios that are likely to present in Australian general practice. Australians love to travel overseas and, increasingly, GPs are asked by patients to provide detailed advice on travel vaccinations for their children. Decisions regarding vaccinations for travelling children can be complex and the advice often differs from that provided for adults. Children differ from adults in their vulnerability to illnesses and side effects of medications. These differences, as well as their status regarding routine childhood vaccinations, all need to be taken into account. As with adults, it is important to consider the location and duration of travel and time until departure. The age of the child is also important and there may be a case for accelerating the routine childhood vaccinations in some children. The aim of this paper is to provide a clear and simple outline of the vaccination recommendations for children travelling overseas from Australia.

Visual impairment significantly impairs the length and quality of life, but little is known of its impact in Indigenous Australians. To investigate the association of disease-specific causes of visual impairment with all-cause mortality. A retrospective cohort analysis. A total of 1347 Indigenous Australians aged over 40 years. Participants visiting remote medical clinics underwent clinical examinations including visual acuity, subjective refraction and slit-lamp examination of the anterior and posterior segments. The major ocular cause of visual impairment was determined. Patients were assessed periodically in these remote clinics for the succeeding 10 years after recruitment. Mortality rates were obtained from relevant departments. All-cause 10-year mortality and its association with disease-specific causes of visual impairment. The all-cause mortality rate for the entire cohort was 29.3% at the 10-year completion of follow-up. Of those with visual impairment, the overall mortality rate was 44.9%. The mortality rates differed for those with visual impairment due to cataract (59.8%), diabetic retinopathy (48.4%), trachoma (46.6%), 'other' (36.2%) and refractive error (33.4%) (P visual impairment from diabetic retinopathy were any more likely to die during the 10 years of follow-up when compared with those without visual impairment (HR 1.70; 95% CI, 1.00-2.87; P = 0.049). Visual impairment was associated with all-cause mortality in a cohort of Indigenous Australians. However, diabetic retinopathy was the only ocular disease that significantly increased the risk of mortality. Visual impairment secondary to diabetic retinopathy may be an important predictor of mortality. © 2017 Royal Australian and New Zealand College of Ophthalmologists.

Australian health professionals' health website recommendation trends.

Usher, Wayne T

2011-08-01

This study was concerned with indentifying motivations and trends associated with a health website recommendation from eight of Australia's major health professions to the health consumer. Health professions included in this study are: psychiatrists, general practitioners, social workers, dietitians, chiropractors, physiotherapists, optometrists and pharmacists. An online survey (www.limesurvey.org) was developed from a common set of questions negotiated between all eight health professions. Survey questions were constructed in an attempt to identify participants' reasons for or against recommending a health website to a patient. A 5-point scale (not, slightly, neutral, moderately, strongly) to measure influence was used throughout the question set. This study indicates that Australian general practitioners (GPs) were the highest Australian health professionals to undertake a health website recommendation (86%), followed by psychiatrists (80%), with the lowest being physiotherapists (42%) and optometrists (33%). A profile of the Australian health professional who recommends a health website is identified as male, aged above 50 years, has had more than 10 years experience, works in a major city, is in private practice and has patient numbers exceeding 500 in a 12-month period (2009). Recommendations from this study include the need to develop mechanisms that identify high-quality online medical information and the development and implementation of Continuing Professional Development (CPD) courses which up-skill health professionals concerning the recommendation of health websites for health care delivery.

Ornamental Stones and Gemstones: The limits of heritage stone designation: The case for and against Australian Precious Opal

geological arena for the first time. Arguments against the international designation of opal may be that the GHSR designation was meant primarily for building stone, not gemstones, even if it is possible to purchase tiles with embedded opal material. It may be argued that opal is also a mineral not a stone or rock however the precious quality of opal results from mineral impurities/ crystal irregularities and specimens of boulder Opal are best regarded as rock. The decision on this matter is best based on whether designating precious opal will beneficially facilitate increased professional, community, national and international awareness of opal especially through scientific investigation, whilst also assisting marketing of opal as a commercial commodity. In addition, the real benefit of grouping opal in a designation that includes building stone needs to be considered? It is likely that not all gemstones could beneficially be designated a heritage stone because the level of manufacturing or processing may be so great that most natural qualities of the material are lost. In addition, Australian opal should most likely be beneficially recognised in an "Australian Precious Opal Province" given the extent of regional opal variation in Australia coupled with the unusual sedimentary aspect of most occurrences.

2018-01-16

Objective The aim of the present systematic review was to examine the enablers for effective health service delivery for Aboriginal Australians. Methods This systematic review was undertaken in accordance with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) statement. Papers were included if they had data related to health services for Australian Aboriginal people and were published between 2000 and 2015. The 21 papers that met the inclusion criteria were assessed using the Effective Public Health Practice Project Quality Assessment Tool for Quantitative Studies. Seven papers were subsequently excluded due to weak methodological approaches. Results There were two findings in the present study: (1) that Aboriginal people fare worse than non-Aboriginal people when accessing usual healthcare services; and (2) there are five enablers for effective health care services for Australian Aboriginal people: cultural competence, participation rates, organisational, clinical governance and compliance, and availability of services. Conclusions Health services for Australian Aboriginal people must be tailored and implementation of the five enablers is likely to affect the effectiveness of health services for Aboriginal people. The findings of the present study have significant implications in directing the future design, funding, delivery and evaluation of health care services for Aboriginal Australians. What is known about the topic? There is significant evidence about poor health outcomes and the 10-year gap in life expectancy between Aboriginal and non-Aboriginal people, and limited evidence about improving health service efficacy. What does this paper add? This systematic review found that with usual health care delivery, Aboriginal people experience worse health outcomes. This paper identifies five strategies in the literature that improve the effectiveness of health care services intended for Aboriginal people. What are the implications for

Members of the order Chlamydiales are known for their potential as human and veterinary bacterial pathogens. Despite this recognition, epidemiological factors such as routes of transmission are yet to be fully defined. Ticks are well known vectors for many other infections with several reports recently describing the presence of bacteria in the order Chlamydiales in these arthropods. Australian wildlife are hosts to an extensive range of tick species. Evidence is also growing that the marsupial hosts these ticks parasitise can also be infected by a number of bacteria in the order Chlamydiales, with at least one species, Chlamydia pecorum, posing a significant conservation threat. In the current study, we investigated the presence and identity of Chlamydiales in 438 ixodid ticks parasitizing wildlife in Australia by screening with a pan-Chlamydiales specific targeting the 16S rRNA gene. Pan-Chlamydiales specific PCR assays confirmed the common presence of Chlamydiales in Australian ticks parasitising a range of native wildlife. Interestingly, we did not detect any Chlamydiaceae, including C. pecorum, the ubiquitous pathogen of the koala. Instead, the Chlamydiales diversity that could be resolved indicated that Australian ticks carry at least six novel Chlamydiales genotypes. Phylogenetic analysis of the 16S rRNA sequences (663 bp) of these novel Chlamydiales suggests that three of these genotypes are associated with the Simkaniaceae and putatively belong to three distinct novel strains of Fritschea spp. and three genotypes are related to the "Ca. Rhabdochlamydiaceae" and putatively belong to a novel genus, Rhabdochlamydia species and strain, respectively. Sequence results suggest Australian wildlife ticks harbour a range of unique Chlamydiales bacteria that belong to families previously identified in a range of arthropod species. The results of this work also suggest that it is unlikely that arthropods act as vectors of pathogenic members of the family

Carboxylic acids in crystallization of macromolecules: learning from successful crystallization experiments.

2014-03-01

The production of macromolecular crystals suitable for structural analysis is one of the most important and limiting steps in the structure determination process. Often, preliminary crystallization trials are performed using hundreds of empirically selected conditions. Carboxylic acids and/or their salts are one of the most popular components of these empirically derived crystallization conditions. Our findings indicate that almost 40 % of entries deposited to the Protein Data Bank (PDB) reporting crystallization conditions contain at least one carboxylic acid. In order to analyze the role of carboxylic acids in macromolecular crystallization, a large-scale analysis of the successful crystallization experiments reported to the PDB was performed. The PDB is currently the largest source of crystallization data, however it is not easily searchable. These complications are due to a combination of a free text format, which is used to capture information on the crystallization experiments, and the inconsistent naming of chemicals used in crystallization experiments. Despite these difficulties, our approach allows for the extraction of over 47,000 crystallization conditions from the PDB. Initially, the selected conditions were investigated to determine which carboxylic acids or their salts are most often present in crystallization solutions. From this group, selected sets of crystallization conditions were analyzed in detail, assessing parameters such as concentration, pH, and precipitant used. Our findings will lead to the design of new crystallization screens focused around carboxylic acids.

On dewetting of thin films due to crystallization (crystallization dewetting).

Habibi, Mehran; Rahimzadeh, Amin; Eslamian, Morteza

2016-03-01

Drying and crystallization of a thin liquid film of an ionic or a similar solution can cause dewetting in the resulting thin solid film. This paper aims at investigating this type of dewetting, herein termed "crystallization dewetting", using PbI2 dissolved in organic solvents as the model solution. PbI2 solid films are usually used in X-ray detection and lead halide perovskite solar cells. In this work, PbI2 films are fabricated using spin coating and the effect of major parameters influencing the crystallization dewetting, including the type of the solvent, solution concentration, drying temperature, spin speed, as well as imposed vibration on the substrate are studied on dewetting, surface profile and coverage, using confocal scanning laser microscopy. Simplified hydrodynamic governing equations of crystallization in thin films are presented and using a mathematical representation of the process, it is phenomenologically demonstrated that crystallization dewetting occurs due to the absorption and consumption of the solution surrounding a growing crystal. Among the results, it is found that a low spin speed (high thickness), a high solution concentration and a low drying temperature promote crystal growth, and therefore crystallization dewetting. It is also shown that imposed vibration on the substrate can affect the crystal size and crystallization dewetting.

Time for National Renewal: Australian adult literacy and numeracy as ‘foundation skills’

Full Text Available Those working in the field of adult literacy and numeracy are currently anticipating changes in the near future as the federal government has flagged the development of a National Foundation Skills Strategy (Australian Government 2010. ‘Foundation skills’ is a term that has recently been suggested as a way of simplifying discussions about literacy and numeracy (Perkins 2009:8, and it has gained traction in various Australian national policy environments (e.g. Gillard 2009, Council of Australian Governments [COAG] Reform Council 2009, Australian Government 2010. Foundation skills appears to encapsulate adult language, literacy and numeracy, and more broadly, it may also include so-called employability skills such as communication and teamwork (Roberts and Wignall 2010:1. In this paper, our main focus is on the adult literacy and numeracy dimensions of what is needed in the policy renewal.

Decolonising Australian Psychology: Discourses, Strategies, and Practice

Directory of Open Access Journals (Sweden)

Pat Dudgeon

2015-08-01

Full Text Available Colonisation in Australia has had a devastating and lasting impact on the wellbeing of Aboriginal and Torres Strait Islander peoples in Australia (herein referred to as Indigenous Australians. This paper discusses the role of psychology in Australia and the negative impact that certain disciplinary theories and practices have had on Indigenous Australians. The impact has been further exacerbated by the failure of mainstream policy makers and mental health practitioners to recognise the key, distinctive cultural and social determinants that contribute to Aboriginal health and wellbeing. There is a growing response by Aboriginal psychologists, critical social theorists, and their allies to decolonise psychological theory and practice to redress this situation. This paper outlines key decolonising strategies that have been effective in interrupting those aspects of psychology that are inimical to Aboriginal wellbeing.

A chlorine-36 dating capability based on the 14UD pelletron accelerator was developed at the Australian National University during 1986 and is now entering the routine measurement phase. It involves a collaboration between the Department of Nuclear Physics, the Australian Atomic Energy Commission and CSIRO Division of Soils. The chlorine-36 dating system is described and some early results are presented for samples of chloride from salt lakes in Western Australia and soil profiles in South Australia

The Effects of Unemployment on the Earnings of Young Australians

OpenAIRE

Matthew Gray

2000-01-01

The high rates of youth unemployment experienced in a number of OECD economies has raised concerns about the effect of this on subsequent earnings. Using the Australian Youth Survey (AYS) a longitudinal survey of Australian youth, we estimate the effects of unemployment on subsequent hourly and weekly earnings. The estimates suggest that, when unobserved heterogeneity is taken into account, it is only long histories of unemployment which have a negative effect on hourly wages. On the other ha...

An island apart? Risks and prices in the Australian cryptomarket drug trade.

Science.gov (United States)

Cunliffe, Jack; Martin, James; Décary-Hétu, David; Aldridge, Judith

2017-12-01

Australia has a reputation as an anomaly with regard to cryptomarket drug trading, with seemingly disproportionately high levels of activity given its relatively small size, high prices and anecdotal accounts of it being a destination where many foreign-based vendors will not sell. This paper aims to investigate these claims from a risk and prices perspective. By analysing data for over 60,000 drug products available for purchase from eight cryptomarkets in January 2016 this work builds a descriptive picture of the Australian online market in comparison to the rest of the world, before moving onto analyse the prices of drugs available to Australian consumers, both online and though conventional drug supply routes. Results show that the Australian online illicit drugs market is of considerable size, internally isolated and with methamphetamine sales being particularly large by comparison to other countries. Australian cryptomarket vendors sell drugs at significantly higher prices than those listed by their foreign counterparts. Online prices are however broadly comparable to street prices, with the exception of methamphetamine where prices appear to be much lower online. These findings indicate that the perceived stringency of Australian border protection inadvertently increases the competitiveness and local market share of domestic cryptomarket vendors via a consumer side 'risk tariff', challenging the traditionally vendor-oriented drugs risk and prices framework.

Current situation and future prospects for the Australian beef industry.

Science.gov (United States)

Greenwood, Paul Leo; Ferguson, Drewe M

2018-04-12

Beef production extends over almost half of Australia, with about 47,000 cattle producers that contribute about 20% ($A12.7 billion GVP) of the total value of farm production in Australia. Australia is one of the world's most efficient producers of cattle and was the world's third largest beef exporter in 2016. The Australian beef industry had 25 million head of cattle in 2016-17, with a national beef breeding herd of 11.5 million head. Australian beef production includes pasture based cow-calf systems, a backgrounding or grow-out period on pasture, and feedlot or pasture finishing. Feedlot finishing has assumed more importance in recent years to assure the eating quality of beef entering the relatively small Australian domestic market, and to enhance the supply of higher value beef for export markets. Maintenance of Australia's preferred status as a quality assured supplier of high value beef produced under environmentally sustainable systems from 'disease-free' cattle is of highest importance. Stringent livestock and meat quality regulations and quality assurance systems, and productivity growth and efficiency across the supply chain to ensure price competiveness, are crucial for continued export market growth in the face of increasing competition. Major industry issues, that also represent research, development and adoption priorities and opportunities for the Australian beef industry have been captured within exhaustive strategic planning processes by the red meat and beef industries. At the broadest level, these issues include consumer and industry support, market growth and diversification, supply chain efficiency, productivity and profitability, environmental sustainability, and animal health and welfare. This review provides an overview of the Australian beef industry including current market trends and future prospects, and major issues and opportunities for the continued growth, development and profitability of the industry.

Full Text Available Since the introduction of wheat into Australia by the First Fleet settlers, germplasm from different geographical origins has been used to adapt wheat to the Australian climate through selection and breeding. In this paper, we used 482 cultivars, representing the breeding history of bread wheat in Australia since 1840, to characterize their diversity and population structure and to define the geographical ancestral background of Australian wheat germplasm. This was achieved by comparing them to a global wheat collection using in-silico chromosome painting based on SNP genotyping. The global collection involved 2,335 wheat accessions which was divided into 23 different geographical subpopulations. However, the whole set was reduced to 1,544 accessions to increase the differentiation and decrease the admixture among different global subpopulations to increase the power of the painting analysis. Our analysis revealed that the structure of Australian wheat germplasm and its geographic ancestors have changed significantly through time, especially after the Green Revolution. Before 1920, breeders used cultivars from around the world, but mainly Europe and Africa, to select potential cultivars that could tolerate Australian growing conditions. Between 1921 and 1970, a dependence on African wheat germplasm became more prevalent. Since 1970, a heavy reliance on International Maize and Wheat Improvement Center (CIMMYT germplasm has persisted. Combining the results from linkage disequilibrium, population structure and in-silico painting revealed that the dependence on CIMMYT materials has varied among different Australian States, has shrunken the germplasm effective population size and produced larger linkage disequilibrium blocks. This study documents the evolutionary history of wheat breeding in Australia and provides an understanding for how the wheat genome has been adapted to local growing conditions.

Determine if balance and technique training implemented adjunct to 1001 male Australian football players' training influenced the activation/strength of the muscles crossing the knee during pre-planned and unplanned sidestepping. Randomized Control Trial. Each Australian football player participated in either 28 weeks of balance and technique training or 'sham' training. Twenty-eight Australian football players (balance and technique training, n=12; 'sham' training, n=16) completed biomechanical testing pre-to-post training. Peak knee moments and directed co-contraction ratios in three degrees of freedom, as well as total muscle activation were calculated during pre-planned and unplanned sidestepping. No significant differences in muscle activation/strength were observed between the 'sham' training and balance and technique training groups. Following a season of Australian football, knee extensor (p=0.023) and semimembranosus (p=0.006) muscle activation increased during both pre-planned sidestepping and unplanned sidestepping. Following a season of Australian football, total muscle activation was 30% lower and peak valgus knee moments 80% greater (p=0.022) during unplanned sidestepping when compared with pre-planned sidestepping. When implemented in a community level training environment, balance and technique training was not effective in changing the activation of the muscles crossing the knee during sidestepping. Following a season of Australian football, players are better able to support both frontal and sagittal plane knee moments. When compared to pre-planned sidestepping, Australian football players may be at increased risk of anterior cruciate ligament injury during unplanned sidestepping in the latter half of an Australian football season.

Report on neutron powder diffraction for the Australian Replacement Research Reactor

International Nuclear Information System (INIS)

Hunter, B.A.

2000-01-01

There is a clear need for two neutron powder diffractometers at the Australian Replacement Research Reactor when it starts operation in 2005. The high-intensity instrument should be capable of measuring a 10mg sample of moderate complexity, or perform single-shot time-resolved experiments with 1-second time slices, or perform stroboscopic measurements with time slices of order 50 microseconds. The high-resolution instrument should have a target resolution of Δd/d∼6x10 -4 , and be capable of collecting data at this resolution within 1-48 hours depending on sample size and crystal complexity. Key questions that need to be answered in the next 9 months include: (1) a detailed study of monochromator options, (2) analysing the detector options for the high-intensity machine and exploring ways in which the solid angle can be maximised for both instruments, (3) whether the instruments are better situated at the reactor face or on super mirror guides, (4) how to integrate the two instruments (physically, if they are only the same guide), and scientifically as regards detailed performance specifications. The user community clearly wants a wide range of sample-environment options, and these are listed in the report. Combinations of these options will be important

2008-07-01

Australian climate is characterised by its more sunny days with mild winter condition compared to Europe. Solar water heating systems have been in the market for many years to provide domestic hot water to main cities in Australia. The market for these systems have been constantly growing and relevant Australian Standards have been developed. This trend is expected to remain in the near future. The paper reports on the results of a recent numerical study on the potential application of a solar combisystem to provide both space heating and domestic hot water (DHW) for a two storey house in Adelaide, Australia. The house space heating requirement was estimated using AccuRate, a building energy rating software developed in Australia, whilst the domestic hot water requirement is based on the Australian Standard AS 4234. The system modelling was carried out using the TRNSYS simulation package. In the study, the thermal performance of flat plate and evacuated type collectors are compared. A number of factors such as effects of tank size, collector slopes and system configuration are investigated. (orig.)

Strategic Human Resource Management and the Australian Public Sector

Directory of Open Access Journals (Sweden)

Karen MANNING

2010-06-01

Full Text Available The connection between human resources and performance in firms in the private sector is well documented. What is less clear is whether the move towards managerialism that has taken place within the Australian public sector during the last twenty years has brought with it some of the features of the relationships between Human Resource Management (HRM and performance experienced within the private sector. The research begins with a review of the literature. In particular the conceptual thinking surrounding the connection between HRM and performance within private sector organizations is explored. Issues of concern are the direction of the relationship between HRM and performance and definitional questions as to the nature and level of HRM to be investigated and the measurement of performance. These conceptual issues are also debated within the context of a public sector and particularly the Australian environment. An outcome of this task is the specification of a set of appropriate parameters for a study of these linkages within Australian public sector organizations.

2010-09-01

Full Text Available The role of calcium in the prevention of bone loss in later life has been well established but little data exist on the adequacy of calcium intakes in elderly Australian women. The aim of this study was to compare the dietary intake including calcium of elderly Australian women with the Australian dietary recommendation, and to investigate the prevalence of calcium supplement use in this population. Community-dwelling women aged 70–80 years were randomly recruited using the Electoral Roll for a 2-year protein intervention study in Western Australia. Dietary intake was assessed at baseline by a 3-day weighed food record and analysed for energy, calcium and other nutrients. A total of 218 women were included in the analysis. Mean energy intake was 7,140 ± 1,518 kJ/day and protein provided 19 ± 4% of energy. Mean dietary calcium intake was 852 ± 298 mg/day, which is below Australian recommendations. Less than one quarter of women reported taking calcium supplements and only 3% reported taking vitamin D supplements. Calcium supplements by average provided calcium 122 ± 427 mg/day and when this was taken into account, total calcium intake increased to 955 ± 504 mg/day, which remained 13% lower than the Estimated Average Requirement (EAR, 1,100 mg/day for women of this age group. The women taking calcium supplements had a higher calcium intake (1501 ± 573 mg compared with the women on diet alone (813 ± 347 mg. The results of this study indicate that the majority of elderly women were not meeting their calcium requirements from diet alone. In order to achieve the recommended dietary calcium intake, better strategies for promoting increased calcium, from both diet and calcium supplements appears to be needed.

Relative motions of the Australian, Pacific and Antarctic plates estimated by the Global Positioning System

Larson, Kristine M.; Freymueller, Jeff

1995-01-01

Global Positioning System (GPS) measurements spanning approximately 3 years have been used to determine velocities for 7 sites on the Australian, Pacific and Antarctic plates. The site velocities agree with both plate model predictions and other space geodetic techniques. We find no evidence for internal deformation of the interior of the Australian plate. Wellington, New Zealand, located in the Australian-Pacific plate boundary zone, moves 20 +/- 5 mm/yr west-southwest relative to the Australian plate. Its velocity lies midway between the predicted velocities of the two plates. Relative Euler vectors for the Australia-Antarctica and Pacific-Antarctica plates agree within one standard deviation with the NUVEL-1A predictions.

2015-01-01

Background Massage is the largest complementary medicine profession in Australia, in terms of public utilisation, practitioner distribution, and number of practitioners, and is being increasingly integrated into the Australian health care system. However, despite the increasing importance of massage therapists in Australian health care delivery, or the increased practice and education obligations this may entail, there has been little exploration of practice, research, and education characteristics of the Australian massage therapist workforce. Purpose To identify practice, research, and education characteristics among the Australian massage therapist workforce. Settings The Australian massage therapy profession. Participants 301 randomly selected members of the Association of Massage Therapists (Australia). Research Design A 15-item, cross-sectional telephone survey. Main Outcomes Measures Massage therapists’ demographic information, practice characteristics, and education and research characteristics. Results Most respondents (73.8%) worked 20 hours per week or less practising massage, nearly half of all respondents (46.8%) treated fewer than 10 massage clients per week, and over three-quarters (81.7%) of respondents were self-employed. Massage therapy was the sole source of income for just over half (55.0%) of the study respondents. Only 5.7% of respondents earned over the average wage ($50,000) through their massage activities. Nearly half of all respondents (43.3%) reported regularly exceeding their continuing professional education (CPE) quota mandated by their professional association. However, 21.1% reported struggling to achieve their CPE quota each year. Over one-third of respondents (35.6%) were not interested in acquiring further CPE points beyond minimum requirements. Respondents were significantly more likely to have an active approach to research if they had higher income (p = .015). Multivariate analysis showed factors associated with access to

The Australian Geodetic Observing Program. Current Status and Future Plans

Johnston, G.; Dawson, J. H.

2015-12-01

Over the last decade, the Australian government has through programs like AuScope, the Asia Pacific Reference Frame (APREF), and the Pacific Sea Level Monitoring (PSLM) Project made a significant contribution to the Global Geodetic Observing Program. In addition to supporting the national research priorities, this contribution is justified by Australia's growing economic dependence on precise positioning to underpin efficient transportation, geospatial data management, and industrial automation (e.g., robotic mining and precision agriculture) and the consequent need for the government to guarantee provision of precise positioning products to the Australian community. It is also well recognised within Australia that there is an opportunity to exploit our near unique position as being one of the few regions in the world to see all new and emerging satellite navigation systems including Galileo (Europe), GPS III (USA), GLONASS (Russia), Beidou (China), QZSS (Japan) and IRNSS (India). It is in this context that the Australian geodetic program will build on earlier efforts and further develop its key geodetic capabilities. This will include the creation of an independent GNSS analysis capability that will enable Australia to contribute to the International GNSS Service (IGS) and an upgrade of key geodetic infrastructure including the national VLBI and GNSS arrays. This presentation will overview the significant geodetic activities undertaken by the Australian government and highlight its future plans.

Huntley, R.B.; Boas, J.F.; Van der Gaast, H.

1998-05-01

The arrangements for the maintenance of the Australian standards for 60 Co are described in detail. The primary standards are a graphite cavity chamber for exposure/air kerma and a graphite calorimeter for absorbed dose. These secondary standards are described and their responses in corresponding 90 Sr reference sources are reported. Accurate ratios between the Australian Radiation Laboratory (ARL) and Australian Nuclear Science and Technology (ANSTO) 90 Sr reference sources are derived for use in future calibrations. The value of 28.8 years for the half-life of 90 Sr is confirmed. The usefulness of 90 Sr reference source measurements in quality assurance is discussed. The charge sensitivity and linearity of the ANSTO electrometers are reported by two different methods and are compared with previous results. Calibration factors for all the secondary standard ionization chambers are given, in terms of exposure, air kerma and absorbed dose to water. Calibration factors are also given for most of the chambers in terms of absorbed dose to graphite. The methods of deriving the calibration factors are explained in detail, including all the corrections applied to both the primary and secondary standard measurements. Three alternative methods of deriving the absorbed dose to water calibration factors are compared. The reported calibration factors are compared with previous results. Changes in the Australian units of exposure, air kerma and absorbed dose to graphite and water are derived from changes in the corresponding calibration factors. The Australian units of exposure and air kerma have not changed significantly since 1990. The Australian unit of absorbed dose to graphite is now 1.1 % smaller than in 1993 and 1.3 % smaller than in 1990. The Australian unit of absorbed dose to water is now 1.4 % smaller than in 1993, but is only 0.9 % smaller than in 1990. Comparisons of the Australian standards of exposure/air kerma and absorbed dose with those of the Bureau

Evaluating Junior Secondary Science Textbook Usage in Australian Schools

McDonald, Christine V.

2016-08-01

A large body of research has drawn attention to the importance of providing engaging learning experiences in junior secondary science classes, in an attempt to attract more students into post-compulsory science courses. The reality of time and resource constraints, and the high proportion of non-specialist science teachers teaching science, has resulted in an overreliance on more transmissive pedagogical tools, such as textbooks. This study sought to evaluate the usage of junior secondary science textbooks in Australian schools. Data were collected via surveys from 486 schools teaching junior secondary (years 7-10), representing all Australian states and territories. Results indicated that most Australian schools use a science textbook in the junior secondary years, and textbooks are used in the majority of science lessons. The most highly cited reason influencing choice of textbook was layout/colour/illustrations, and electronic technologies were found to be the dominant curricula material utilised, in addition to textbooks, in junior secondary science classes. Interestingly, the majority of respondents expressed high levels of satisfaction with their textbooks, although many were keen to stress the subsidiary role of textbooks in the classroom, emphasising the textbook was `one' component of their teaching repertoire. Importantly, respondents were also keen to stress the benefits of textbooks in supporting substitute teachers, beginning teachers, and non-specialist science teachers; in addition to facilitating continuity of programming and staff support in schools with high staff turnover. Implications from this study highlight the need for high quality textbooks to support teaching and learning in Australian junior secondary science classes.

Psychiatric advance directives in Australian mental-health legislation.

Ouliaris, Calina; Kealy-Bateman, Warren

2017-12-01

Following the recent widespread reform of mental-health legislation in Australia, psychiatric advance directives (PADs) have now been incorporated in four jurisdictions. We contextualise the potential role for PADs within the Australian legal framework and note their varying introduction across jurisdictions, with a focus on progressive legislation in the Australian Capital Territory (ACT). The formal recognition of PADs effectively shifts the trajectory of mental-health law towards a stronger recognition of consumer autonomy, albeit to varying degrees across jurisdictions. The most inspiring of these changes may be seen in the ACT Act, where an innovative framing of PAD provisions creates a safe space for clinicians and patients to engage, build therapeutic alliances and develop appropriate frameworks for further change.

The Australian Natural Disaster Resilience Index Martin Thoms, Melissa Parsons, Phil Morley Bushfire and Natural Hazards Cooperative Research Centre, Geography and Planning, University of New England, Armidale NSW 2351, Australia. Natural hazard management policy directions in Australia - and indeed internationally - are increasingly being aligned to ideas of resilience. Resilience to natural hazards is the ability of individuals and communities to cope with disturbance and adversity and to maintain adaptive behaviour. Operationalizing the measurement and assessment of disaster resilience is often undertaken using a composite index, but this exercise is yet to be undertaken in Australia. The Australian Natural Disaster Resilience Index is a top-down, national scale assessment of the resilience of communities to natural hazards. Resilience is assessed based on two sets of capacities: coping and adaptive capacities. Coping capacity relates to the factors influencing the ability of a community to prepare for, absorb and recover from a natural hazard event. Adaptive capacity relates to the arrangements and processes that enable adjustment through learning, adaptation and transformation. Indicators are derived under themes of social character, economic capital, infrastructure and planning, emergency services, community capital, information and engagement and governance/leadership/policy, using existing data sets (e.g. census data) or evaluation of policy and procedure (e.g. disaster management planning). A composite index of disaster resilience is then computed for each spatial division, giving national scale coverage. The results of the Australian Natural Disaster Resilience Index will be reported in a State of Disaster Resilience report, due in 2018. The index is co-designed with emergency service agencies, and will support policy development, planning, community engagement and emergency management.

The Australia Geothermal Energy Group is an alliance of companies, government agencies and research organizations with an interest in promoting geothermal energy use. Hot rocks (HR) geothermal energy is a valued addition to the portfolio of safe, secure and competitive energy supplies because it offers the potential of inexhaustible geothermal heat energy with zero emissions. Australia's vast HR resources have attracted global interest and government support for HR projects, which call upon integrated expertise from the petroleum minerals and power industries. Funding from the Australian government is aimed at reducing critical, sector-wide uncertainties and equates to nearly 25 per cent of the cost of the private sector's field efforts to date. A national HR resource assessment and a road-map for the commercialization of Australian HR plays will be published in 2008 to help in the decision making process by portfolio managers. The challenges and prospects for HR projects in Australia were presented. It has been estimated that converting only 1 per cent of Australia's crustal energy from depths of 5 km and 150 degrees C to electricity would supply 26,000 years of Australia's 2005 primary power use. The factors that distinguish Australian HR resources include abundant radioactive granites and areas of recent volcanic activity; and, Australia is converging with Indonesia on a plate scale resulting in common, naturally occurring subhorizontally fractured basement rocks that are susceptible to hydraulic fracture stimulation. Most projects are focused on HR to develop enhanced or engineered geothermal systems (EGS) to fuel binary power plants. Approximately 80 percent of these projects are located in South Australia. 14 refs., 3 tabs., 3 figs.

RNA Crystallization

Golden, Barbara L.; Kundrot, Craig E.

2003-01-01

RNA molecules may be crystallized using variations of the methods developed for protein crystallography. As the technology has become available to syntheisize and purify RNA molecules in the quantities and with the quality that is required for crystallography, the field of RNA structure has exploded. The first consideration when crystallizing an RNA is the sequence, which may be varied in a rational way to enhance crystallizability or prevent formation of alternate structures. Once a sequence has been designed, the RNA may be synthesized chemically by solid-state synthesis, or it may be produced enzymatically using RNA polymerase and an appropriate DNA template. Purification of milligram quantities of RNA can be accomplished by HPLC or gel electrophoresis. As with proteins, crystallization of RNA is usually accomplished by vapor diffusion techniques. There are several considerations that are either unique to RNA crystallization or more important for RNA crystallization. Techniques for design, synthesis, purification, and crystallization of RNAs will be reviewed here.

Congruent biogeographical disjunctions at a continent-wide scale: Quantifying and clarifying the role of biogeographic barriers in the Australian tropics

Aim To test whether novel and previously hypothesized biogeogaphic barriers in the Australian Tropics represent significant disjunction points or hard barriers, or both, to the distribution of plants. Location Australian tropics: Australian Monsoon Tropics and Australian Wet Tropics. Methods The presence or absence of 6,861 plant species was scored across 13 putative biogeographic barriers in the Australian Tropics, including two that have not previously been recognised. Randomizations of these data were used to test whether more species showed disjunctions (gaps in distribution) or likely barriers (range limits) at these points than expected by chance. Results Two novel disjunctions in the Australian Tropics flora are identified in addition to eleven putative barriers previously recognized for animals. Of these, eleven disjunction points (all within the Australian Monsoon Tropics) were found to correspond to range-ending barriers to a significant number of species, while neither of the two disjunctions found within the Australian Wet Tropics limited a significant number of species’ ranges. Main conclusions Biogeographic barriers present significant distributional limits to native plant species in the Australian Monsoon Tropics but not in the Australian Wet Tropics. PMID:28376094

A crystal barrel

CERN Multimedia

2007-01-01

The production of crystals for the barrel of the CMS electromagnetic calorimeter has been completed. This is an important milestone for the experiment, which received the last of its 62,960 crystals on 9 March. The members of the team responsible for the crystal acceptance testing at CERN display the last crystal for the CMS electromagnetic calorimeter barrel. From left to right: Igor Tarasov, Etiennette Auffray and Hervé Cornet.One of the six machines specially developed to measure 67 different parameters on each crystal. Igor Tarasov is seen inserting the last batch of crystals into the machine. The last of the 62,960 CMS barrel crystals arrived at CERN on 9 March. Once removed from its polystyrene protection, this delicate crystal, like thousands of its predecessors, will be inserted into the last of the 36 supermodules of the barrel electromagnetic calorimeter in a few days' time. This marks the end of an important chapter in an almost 15-year-long journey by the CMS crystals team, some of whose member...

The Frontier Speaks Back: Two Australian Artists Working in Paris and London

Directory of Open Access Journals (Sweden)

Catherine Margaret Speck

2013-07-01

Full Text Available Australian artists living and working in Paris and London in the Belle Époque and modern eras had a deep engagement with cosmopolitanism in cities that were at the frontiers of international modernism. They experienced the liberation of putting aside issues of nation, and of working in large, alienating but culturally challenging multi-nation environs in the pre and post war years. This paper will explore how two women artists, Hilda Rix in Paris, a hub of internationalism; and Nora Heysen in London, a city ill-described in the Empire language of ‘home’ for Australians, connected with and articulated cosmopolitan culture. Expatriatism facilitated an offshore variant of Australian modernism.

Heavy Metals Bioaccumulation by Iranian and Australian Earthworms (Eisenia fetida in the Sewage Sludge Vermicomposting

Full Text Available Vermicomposting of organic waste has an important part to play in an integrated waste management strategy. In this study, the possibility of heavy metals accumulation with two groups of Iranian and Australian earthworms in sewage sludge vermicompost was investigated. Eisenia fetida was the species of earthworms used in the vermicomposting process. The bioaccumulation of Cr, Cd, Pb, Cu, and Zn as heavy metals by Iranian and Australian earthworms was studied. The results indicated that heavy metals concentration decreased with increasing vermicomposting time. Comparison of the two groups of earthworms showed that the Iranian earthworms consumed higher quantities of micronutrients such as Cu and Zn comparing with the Australian earthworms, while the bioaccumulation of non-essential elements such as Cr, Cd, and Pb by the Australian group was higher. The significant decrease in heavy metal concentrations in the final vermicompost indicated the capability of both Iranian and Australian E.fetida species in accumulating heavy metals in their body tissues.

Although the prevalence of dementia in remote living Aboriginal Australians is one of the highest in the world, the factors associated with dementia in this population are yet to be examined. This study was designed to determine the demographic, lifestyle and clinical factors associated with dementia in Aboriginal Australians living in the Kimberley region of Western Australia. A total of 363 Aboriginal Australians aged over 45 years from the Kimberley region were selected by semi-purposeful sampling. The factors analysed for association with dementia were age, sex, education, smoking, chewing tobacco, alcohol, head injury, heart disease, hypertension, diabetes, previous stroke, epilepsy, falls, mobility, incontinence, urinary problems, vision and hearing. This exposure data was collected from participants' and informants' reports using the Kimberley Indigenous Cognitive Assessment and specialist review, and medical records. Factors associated with dementia included older age, male gender (OR 3.1, 95%CI 1.4, 6.8) and no formal education (OR 2.7, 95%CI 1.1, 6.7) and after adjusting for age, sex and education, dementia was associated with current smoking (OR 4.5, 95%CI 1.1, 18.6), previous stroke (OR 17.9, 95%CI 5.9, 49.7), epilepsy (OR 33.5, 95%CI 4.8, 232.3), head injury (OR 4.0, 95%CI 1.7, 9.4), and poor mobility, incontinence and falls. Interventions aimed at better management or prevention of the modifiable factors identified could reduce dementia risk in Aboriginal populations.

2018-02-01

To investigate whether preseason training plans for Australian football can be computer generated using current training-load guidelines to optimize injury-risk reduction and performance improvement. A constrained optimization problem was defined for daily total and sprint distance, using the preseason schedule of an elite Australian football team as a template. Maximizing total training volume and maximizing Banister-model-projected performance were both considered optimization objectives. Cumulative workload and acute:chronic workload-ratio constraints were placed on training programs to reflect current guidelines on relative and absolute training loads for injury-risk reduction. Optimization software was then used to generate preseason training plans. The optimization framework was able to generate training plans that satisfied relative and absolute workload constraints. Increasing the off-season chronic training loads enabled the optimization algorithm to prescribe higher amounts of "safe" training and attain higher projected performance levels. Simulations showed that using a Banister-model objective led to plans that included a taper in training load prior to competition to minimize fatigue and maximize projected performance. In contrast, when the objective was to maximize total training volume, more frequent training was prescribed to accumulate as much load as possible. Feasible training plans that maximize projected performance and satisfy injury-risk constraints can be automatically generated by an optimization problem for Australian football. The optimization methods allow for individualized training-plan design and the ability to adapt to changing training objectives and different training-load metrics.

The Australian Centre for Minesite Rehabilitation Research (ACMRR) is a joint venture between the Australian mining industry through the Australian Mineral Industries Research Association Ltd. (AMIRA) and three of the organizations working most actively in this area in Australia: CSIRO Minesite Rehabilitation Research Program; University of Queensland Centre for Mined Land Rehabilitation; and Curtin University Mulga Research Centre. The ACMRR was established in July 1993 to provide a national framework to conduct Strategic Research into minesite rehabilitation. It is an industry led and funded initiative. The Goals of the Centre include: to conduct strategic research into minesite rehabilitation to provide sustainable environmental solutions which are acceptable to industry, government and the community; to be recognized as a center of excellence undertaking commissioned research on minesite rehabilitation in an independent and thorough manner; to provide scientific and technological foundations to facilitate industry and government in setting acceptable standards; to act as networking and communications focus; and to enhance education and training in minesite rehabilitation. Strategic Research Programs in: Water Systems--downstream surface and groundwater quality; Land--the long-term behavior and stability of constructed landforms; Ecosystems--the long-term sustainability of constructed landforms; Waste--the long-term treatment and disposal of waste products; will allow the ACMRR to achieve these goals through specific research projects in these areas, developed with industry sponsors. This paper will discuss their progress to date, research projects underway, and plans for the future

2018-02-10

Given recent rises in out-of-pocket health expenses, we examined the financial well-being of older Australians with multiple health conditions and disabilities. The 2014 General Social Survey was used to measure the: (i) current financial position; (ii) propensity to experience financial difficulties; and (iii) types of behaviours older people with multiple health conditions engage in to improve financial resilience. Compared to older Australians with no health conditions, respondents with multiple health conditions had lower incomes and assets and a higher propensity to hold consumer debt (once controls were included). They were at a higher risk of cash flow difficulties, dissaving to meet day-to-day living expenses and exclusion from financial providers. However, the majority of people with multiple health conditions engaged in financially resilient behaviours. Many older Australians with multiple health conditions were in a financially precarious situation with implications for the ability to afford ongoing increases in out-of-pocket health-care costs. © 2018 AJA Inc.

Fires in the Australian Capital Territory

2003-01-01

The height and extent of billowing smoke plumes from bushfires near Canberra, the Australian capital, are illustrated by these views from the Multi-angle Imaging SpectroRadiometer (MISR). The images were acquired on January 18, 2003. Never before had fires of this magnitude come so close to Australia's capital. Four people lost their lives and over 500 homes were destroyed, mostly in the southwestern suburbs. Australia's famous Mount Stromlo Observatory, located immediately west of the city, was also incinerated by the fires.The top panel portrays a natural-color view from MISR's nadir camera, in which the eastern portion of the Australian Capital Territory is located south of a pale, ephemeral lake in the upper left-hand corner (Lake George). Several smoke plumes originate within the eastern part of the Australian Capital Territory, while the major plumes originate to the west of the image area. The Australian Capital Territory and much of New South Wales are completely obscured by the smoke, which is driven by fierce westerly winds and extends eastward to the coast and over the Pacific Ocean.The lower panel provides a stereoscopically retrieved height field of the clouds and smoke plumes. The greenish areas indicate where smoke plumes extend several kilometers above a bank of patchy stratus clouds below. A few high clouds appear near the bottom of the image. Wind retrievals were excluded from this image in order to generate a smooth and continuous field. Although relative height variations are well-represented here, the inclusion of wind retrievals for this scene reduces the actual cloud height results by 1 to 2 kilometers. Areas where heights could not be retrieved are shown as dark gray.The Multi-angle Imaging SpectroRadiometer observes the daylit Earth continuouslyand every 9 days views the entire globe between 82 degrees north and 82 degrees south latitude. This data product was generated from a portion of the imagery acquired during Terra orbit 16421. The

The areas were biopsied and histopathological examination demonstrated orthokeratotic hyperkeratosis with keratinocytes containing eosinophilic intranuclear inclusions. Molecular diagnostics confirmed the presence of a herpesvirus in the affected tissues. This is the first recorded case of herpesvirus infection in an Australian freshwater turtle species. © 2015 Australian Veterinary Association.

Effects of impurities on crystal growth in fructose crystallization

Science.gov (United States)

Chu, Y. D.; Shiau, L. D.; Berglund, K. A.

1989-10-01

The influence of impurities on the crystallization of anhydrous fructose from aqueous solution was studied. The growth kinetics of fructose crystals in the fructose-water-glucose and fructose-water-difructose dianhydrides systems were investigated using photomicroscopic contact nucleation techniques. Glucose is the major impurity likely to be present in fructose syrup formed during corn wet milling, while several difructose dianhydrides are formed in situ under crystallization conditions and have been proposed as a cause in the decrease of overall yields. Both sets of impurities were found to cause inhibition of crystal growth, but the mechanisms responsible in each case are different. It was found that the presence of glucose increases the solubility of fructose in water and thus lowers the supersaturation of the solution. This is probably the main effect responsible for the decrease of crystal growth. Since the molecular structures of difructose dianhydrides are similar to that of fructose, they are probably "tailor-made" impurities. The decrease of crystal growth is probably caused by the incorporation of these impurities into or adsorption to the crystal surface which would accept fructose molecules in the orientation that existed in the difructose dianhydride.

Australian natural gas market outlook

International Nuclear Information System (INIS)

Anon.

2004-01-01

A new study of the Australian natural gas industry by leading Australian economics and policy consultancy ACIL Tasman highlights the significant supply and demand side uncertainties currently facing the industry. The ACIL Tasman 'Australian Gas Market Review and Outlook 2004' study presents modelling results for three supply/demand scenarios in Eastern Australia and two in Western Australia. The results show that, even under moderate assumptions about future levels of gas demand growth, major supply-side investment is likely to be needed over the next ten to fifteen years. The base supply/demand scenario for Eastern Australia and Northern Territory, illustrated in Figure 1, shows that even allowing for substantial new discoveries in existing production basins and major expansion of coal seam methane production, in the absence of a northern gas connection to the eastern states (Timor Sea or PNG Highlands) a significant supply gap will begin to emerge from around 2013. The study identifies several supply-side options for Eastern Australia - new discoveries in the established production provinces in Bass Strait and Central Australia; greenfield developments such as the Otway Basin offshore from Victoria and South Australia; continuing expansion of coal seam methane production in Queensland and New South Wales; and gas from Papua New Guinea, Timor Sea or from the North West Shelf region delivered via a trans-continental pipeline. The study concludes that it is unlikely that any single option will suffice to meet future demand. Almost inevitably, a combination of these sources will be needed if anticipated growth opportunities are to be met. With regard to prices, the study shows that in the short to medium term the outlook is for some real reductions in wholesale prices in most regional markets. This reflects increasing levels of upstream competition and declining real costs of pipeline transportation. However in the longer term, supply-side constraints will tend to

International medical students and migration: the missing dimension in Australian workforce planning?

To investigate the potential contribution of international medical students at Australian universities to the Australian medical workforce. A prospective survey in 2006-2007 of 619 international medical students in their final 2 years of undergraduate- and graduate-entry medical courses across eight Australian universities, followed by a 2009 survey of 88 international medical graduates of the University of Melbourne (most of whom were respondents of the earlier survey), assessing the correlation between students' intended place of internship and their actual place of internship. The survey respondents' preferred internship location; the proportion of respondents who intended to remain in practice in Australia long term; and correlation between respondents' intended internship locations and actual placements in their first postgraduate year. Of the 619 international medical students surveyed in 2006, 358 (58%) responded. Most planned to undertake Australian internships and seek permanent-resident status, although a third were undecided about their long-term plans. Nationality was a highly significant variable. Most preferred city rather than regional or rural training locations and expressed interest in migrating to Australia. The 2009 survey of the University of Melbourne's 2008 medical graduates showed a high correlation between students' plans in their last two years of study and outcomes in their first postgraduate year, with 73% accepting Victorian internships for 2009. International medical students studying at Australian universities represent a substantial and highly acceptable medical workforce resource for Australia. Their requirement for internships needs to be considered in, and should influence, infrastructure planning.

Health literacy and the Internet: a study on the readability of Australian online health information.

Cheng, Christina; Dunn, Matthew

2015-08-01

Almost 80% of Australian Internet users seek out health information online so the readability of this information is important. This study aimed to evaluate the readability of Australian online health information and determine if it matches the average reading level of Australians. Two hundred and fifty-one web pages with information on 12 common health conditions were identified across sectors. Readability was assessed by the Flesch-Kincaid (F-K), Simple Measure of Gobbledygook (SMOG) and Flesch Reading Ease (FRE) formulas, with grade 8 adopted as the average Australian reading level. The average reading grade measured by F-K and SMOG was 10.54 and 12.12 respectively. The mean FRE was 47.54, a 'difficult-to-read' score. Only 0.4% of web pages were written at or below grade 8 according to SMOG. Information on dementia was the most difficult to read overall, while obesity was the most difficult among government websites. The findings suggest that the readability of Australian health websites is above the average Australian levels of reading. A quantifiable guideline is needed to ensure online health information accommodates the reading needs of the general public to effectively use the Internet as an enabler of health literacy. © 2015 Public Health Association of Australia.

We present an Aboriginal Australian genomic sequence obtained from a 100-year-old lock of hair donated by an Aboriginal man from southern Western Australia in the early 20th century. We detect no evidence of European admixture and estimate contamination levels to be below 0.5%. We show that Aboriginal Australians are descendants of an early human dispersal into eastern Asia, possibly 62,000 to 75,000 years ago. This dispersal is separate from the one that gave rise to modern Asians 25,000 to ...

Brake, Felicity; Ross, Tom; Holds, Geoffrey; Kiermeier, Andreas; McLeod, Catherine

2014-12-01

Impending international policies for norovirus in oysters and the lack of Australian data suggested there was a need to undertake a national survey of norovirus in oysters. Two geographically distinct oyster-growing areas from each of three Australian states were sampled on 4 occasions during 2010 and 2011. The sites selected were considered by state shellfish authorities to be the most compromised with respect to the potential for human faecal contamination as identified by shoreline surveys. The oysters were tested for norovirus GI, GII and Escherichia coli. Norovirus GII was detected in two of 120 (1.7%) samples and norovirus GI was not detected. One of the norovirus positive samples was cloned and sequenced as GII.3. Five of 120 (4.2%) samples were found to have more than the guidance concentration of 230 E. coli per 100 g of shellfish but these samples did not contain detectable concentrations of norovirus. The apparently low prevalence of norovirus in oysters from Australian growing areas supports epidemiological data that suggests norovirus contamination of Australian oysters is rare. The results from this study emphasise the need for future norovirus control measures for shellfish to be commensurate with the risk associated with the growing area. Copyright © 2014 Elsevier Ltd.

Quality of claims and references found in Australian pharmacy journal advertisements.

Science.gov (United States)

Mandoh, Mona; Curtain, Colin Michael

2017-10-01

To evaluate the quality of pharmaceutical advertisement claims and supporting references in Australian pharmacy journals that target community pharmacists. All full-page advertisements for a medicinal product, found in two Australian pharmacy journals from the year 2012 to 2015 were included. Advertisement claims and references were evaluated by claim type (unambiguous to immeasurable) and level of evidence (strong to irrelevant) in supporting references. Two hundred and ninety distinct advertisements and 598 claims were identified, with a median of 2 claims per advertisement. Twenty-seven percent of claims were unambiguous, 40% were vague, 16% were emotive/immeasurable and 17% were non-clinical or other marketing claims. Half of all claims were referenced. Although 68% of unambiguous claims were referenced, 63% of those were supported by studies that were funded directly or indirectly by pharmaceutical companies. Only 13% of claims were supported with strong or moderate independent evidence. Pharmaceutical advertisements continue to present vague and emotive claims with little independent supporting evidence. Pharmacists need to be aware of these limitations when providing patient care. Increased awareness of this issue among pharmaceutical companies, Australian pharmaceutical journal publishers, regulators and pharmacists will assist in promoting optimised healthcare outcomes for the Australian public. © 2016 Royal Pharmaceutical Society.

Exploring Environmental Disclosure in SelectedAustralian Multinationals under the GRI Guidelines

Omar Al Farooque

2014-09-01

Full Text Available This paper explores changes in environmental reporting among Australian MNEs between 2004 and 2007, using the GRI guidelines, and explains how GRI transformation (from G2 to G3 leads to changes in environmental disclosure aspects along with their association with company size, profitability, industry sector. Applying Wilcoxon matched pair signed ranked and Spearman rank correlation tests, twenty companies from the Australian SAM Sustainability Index (AuSSI are examined to identify the extent of changes on specific aspects of environmental disclosure. The findings of the paper document a significant increase in environmental reporting in Australian companies. In particular, reporting has increased for energy, emissions and environmental management followed by water, overall, materials, transport and product/services aspects. However, a shift in emphasis from compliance and biodiversity aspects associated with climate changes and resource preservation is also evident. Again, the majority of changes occurred in companies operating in environmentally sensitive industries with industry sector having significant relationship with a few environmental disclosure aspects, the study shows no significant effect of company size and profitability on different environmental disclosure aspects. These evidences indicate that external forces (such as, legislation, industry sensitiveness to environment, and stakeholder awareness and pressure rather than internal factors are more effective to influence and determine environmental disclosure in Australian companies.

2015-06-01

Because national surveys of people living with psychotic disorders tend to exclude people with low English proficiency (LEP), little is known of their economic and social functioning. Culturally influenced explanatory models may result in delayed presentation and poorer functioning. The study aimed to compare the functioning of LEP Vietnamese-Australian and Australian-born patients with psychosis and to investigate the Vietnamese-Australians' pathways to care. In all, 19 LEP Vietnamese-Australians, previously excluded from the Australian Survey of High Impact Psychosis (SHIP), were matched with 15 Australian-born controls, and interviewed by a Vietnamese bilingual mental health professional using the SHIP Interview Schedule. The Vietnamese-Australian patients were significantly more likely to live with family, rate spirituality as important and participate in community rehabilitation programs. Their work, social and independent functioning, was better than the controls. The groups did not differ in mental health services received and satisfaction with services. Although half of Vietnamese-Australians attributed mental illness to supernatural, among other causes, none had consulted traditional healers. Despite LEP, Vietnamese-Australians with psychosis showed comparable or better functioning than Australian-born patients. Further investigation is recommended into LEP patients' clinical and social recovery and the role of language communities' support networks. © The Author(s) 2014.

Australian Aboriginal Geomythology: Eyewitness Accounts of Cosmic Impacts?

Science.gov (United States)

Hamacher, Duane W.; Norris, Ray P.

2009-12-01

Descriptions of cosmic impacts and meteorite falls are found throughout Australian Aboriginal oral traditions. In some cases, these texts describe the impact event in detail, sometimes citing the location, suggesting that the events were witnessed. We explore whether cosmic impacts and meteorite falls may have been witnessed by Aboriginal Australians and incorporated into their oral traditions. We discuss the complications and bias in recording and analysing oral texts but suggest that these texts may be used both to locate new impact structures or meteorites and model observed impact events. We find that, while detailed Aboriginal descriptions of cosmic impacts are abundant in the literature, there is currently no physical evidence connecting these accounts to impact events currently known to Western science.

High rates of dementia have been observed in Aboriginal Australians. This study aimed to describe childhood stress in older Aboriginal Australians and to examine associations with late-life health and dementia. A cross-sectional study with a representative sample of community-dwelling older Aboriginal Australians. Urban and regional communities in New South Wales, Australia. 336 Aboriginal and/or Torres Strait Islander Australians aged 60-92 years, of whom 296 were included in the current analyses. Participants completed a life course survey of health, well-being, cognition, and social history including the Childhood Trauma Questionnaire (CTQ), with consensus diagnosis of dementia and Alzheimer disease. CTQ scores ranged from 25-117 (median: 29) and were associated with several adverse childhood indicators including separation from family, poor childhood health, frequent relocation, and growing up in a major city. Controlling for age, higher CTQ scores were associated with depression, anxiety, suicide attempt, dementia diagnosis, and, specifically, Alzheimer disease. The association between CTQ scores and dementia remained significant after controlling for depression and anxiety variables (OR: 1.61, 95% CI: 1.05-2.45). In contrast, there were no significant associations between CTQ scores and smoking, alcohol abuse, diabetes, or cardiovascular risk factors. Childhood stress appears to have a significant impact on emotional health and dementia for older Aboriginal Australians. The ongoing effects of childhood stress need to be recognized as people grow older, particularly in terms of dementia prevention and care, as well as in populations with greater exposure to childhood adversity, such as Aboriginal Australians.

The crystal structure and magnetic susceptibility behaviour of UOSe single crystals have been studied. UOSe crystalizes in the tetragonal PbFC1-type structure (space group P4/nmm) with the lattice parameters: a = 390.38(5) pm and c = 698.05(9) pm. It orders antiferromagnetically at T N =100±2 K and exhibits a very strong anisotropy in the susceptibility vs temperature variation. The magnetic and thermodynamic properties of UOSe are successfully interpreted in the framework of a perturbative ab initio crystal field approach. (Author)

The crystal structure and magnetic susceptibility behaviour of UOSe single crystals have been studied. UOSe crystalizes in the tetragonal PbFC1-type structure (space group P4/nmm) with the lattice parameters: a = 390.38(5) pm and c = 698.05(9) pm. It orders antiferromagnetically at T[sub N]=100[+-]2 K and exhibits a very strong anisotropy in the susceptibility vs temperature variation. The magnetic and thermodynamic properties of UOSe are successfully interpreted in the framework of a perturbative ab initio crystal field approach. (Author).

The objectives of the study were to assess the relationship between various player and game factors and risk of concussion; and to assess the reliability of video analysis for mechanistic assessment of concussion in Australian football. Prospective cohort study. All impacts and collisions resulting in concussion were identified during the 2011 Australian Football League season. An extensive list of factors for assessment was created based upon previous analysis of concussion in Australian Football League and expert opinions. The authors independently reviewed the video clips and correlation for each factor was examined. A total of 82 concussions were reported in 194 games (rate: 8.7 concussions per 1000 match hours; 95% confidence interval: 6.9-10.5). Player demographics and game variables such as venue, timing of the game (day, night or twilight), quarter, travel status (home or interstate) or score margin did not demonstrate a significant relationship with risk of concussion; although a higher percentage of concussions occurred in the first 5min of game time of the quarter (36.6%), when compared to the last 5min (20.7%). Variables with good inter-rater agreement included position on the ground, circumstances of the injury and cause of the impact. The remainder of the variables assessed had fair-poor inter-rater agreement. Common problems included insufficient or poor quality video and interpretation issues related to the definitions used. Clear definitions and good quality video from multiple camera angles are required to improve the utility of video analysis for concussion surveillance in Australian football.

Australian Hospital-Based Nurse Educators' Perceptions of Their Role.

Science.gov (United States)

Thornton, Karleen

2018-06-01

This article presents the findings from a phenomenological study that explored the understandings of Australian hospital-based nurse educators' experiences of their role. Purposive sampling resulted in 11 nurse educators from four large metropolitan hospitals within an Australian jurisdiction. The participants were asked how they understand their role and translate that understanding into practice. Thematic analysis identified four themes representative of nurse educators' understanding of their role: Becoming an Educator, Capability Building, Panacea, and Tension. A coherent picture emerged from subthemes highlighting that nurse educators were undervalued and value is added. Being undervalued and value adding are translated into nurse educator practice as resilience, being educationally literate, investing, and having a presence. This article identifies a gap in knowledge related to understanding the nurse educator role and informs recruitment and subsequent retention of nurses into nurse educator roles at a time when the nursing workforce in Australia and internationally is about to experience a major shortfall. Findings are specific to the Australian context and are not necessarily generalizable to other hospital jurisdictions. J Contin Educ Nurs. 2018;49(6):274-281. Copyright 2018, SLACK Incorporated.

Perspectives on the working hours of Australian junior doctors.

Glasgow, Nicholas J; Bonning, Michael; Mitchell, Rob

2014-01-01

The working hours of junior doctors have been a focus of discussion in Australia since the mid-1990s. Several national organizations, including the Australian Medical Association (AMA), have been prominent in advancing this agenda and have collected data (most of which is self-reported) on the working hours of junior doctors over the last 15 years. Overall, the available data indicate that working hours have fallen in a step-wise fashion, and AMA data suggest that the proportion of doctors at high risk of fatigue may be declining. It is likely that these changes reflect significant growth in the number of medical graduates, more detailed specifications regarding working hours in industrial agreements, and a greater focus on achieving a healthy work-life balance. It is notable that reductions in junior doctors' working hours have occurred despite the absence of a national regulatory framework for working hours. Informed by a growing international literature on working hours and their relation to patient and practitioner safety, accreditation bodies such as the Australian Commission on Safety and Quality in Health Care (ACSQHC) and the Australian Medical Council (AMC) are adjusting their standards to encourage improved work and training practices.

Chinese and Australians showed difference in mental time travel in emotion and content but not specificity

Full Text Available Mental time travel refers to the ability to recall episodic past and imagine future events. The present study aimed to investigate cultural differences in mental time travel between Chinese and Australian university students. A total of 231 students (108 Chinese & 123 Australians participated in the study. Their mental time travel abilities were measured by the Sentence Completion for Events from the Past Test (SCEPT and the Sentence Completion for Events in the Future Test (SCEFT. Results showed that there were no cultural differences in the number of specific events generated for the past or future. Significant differences between the Chinese and Australian participants were found mainly in the emotional valence and content of the events generated. Both Chinese and Australian participants generated more specific positive events compared to negative events when thinking about the future and Chinese participants were more positive about their past than Australian participants when recalled specific events. For content, Chinese participants recalled more events about their interpersonal relationships, while Australian participants imagined more about personal future achievements. These findings shed some lights on cultural differences in episodic past and future thinking.

Nanoparticles in liquid crystals, and liquid crystals in nanoparticles

de Pablo, Juan

2015-03-01

Liquid crystals are remarkably sensitive to interfacial interactions. Small perturbations at a liquid crystal interface, for example, can be propagated over relatively long length scales, thereby providing the basis for a wide range of applications that rely on amplification of molecular events into macroscopic observables. Our recent research efforts have focused on the reverse phenomenon; that is, we have sought to manipulate the interfacial assembly of nanoparticles or the organization of surface active molecules by controlling the structure of a liquid crystal. This presentation will consist of a review of the basic principles that are responsible for liquid crystal-mediated interactions, followed by demonstrations of those principles in the context of two types of systems. In the first, a liquid crystal is used to direct the assembly of nanoparticles; through a combination of molecular and continuum models, it is found that minute changes in interfacial energy and particle size lead to liquid-crystal induced attractions that can span multiple orders of magnitude. Theoretical predictions are confirmed by experimental observations, which also suggest that LC-mediated assembly provides an effective means for fabrication of plasmonic devices. In the second type of system, the structure of a liquid crystal is controlled by confinement in submicron droplets. The morphology of the liquid crystal in a drop depends on a delicate balance between bulk and interfacial contributions to the free energy; that balance can be easily perturbed by adsorption of analytes or nanoparticles at the interface, thereby providing the basis for development of hierarchical assembly of responsive, anisotropic materials. Theoretical predictions also indicate that the three-dimensional order of a liquid crystal can be projected onto a two-dimensional interface, and give rise to novel nanostructures that are not found in simple isotropic fluids.

A novel crystal bender for an X-ray undulator beamline as part of a fast double crystal monochromator development for full EXAFS energy range was characterized. Rocking curves of the monochromator crystal system were recorded under different heat loads and bending forces of the indirectly cooled first Si(1 1 1) crystal. The monochromator development implements new piezo-driven tilt tables with wide angular range to adjust the crystals' Bragg angles and a high pressure actuated bender mechanism for the first crystal.

Hidden biases in Australian energy policy

International Nuclear Information System (INIS)

Schlaepfer, August

2009-01-01

The challenges in developing technology for the capture and storage of CO 2 from coal, oil and gas power generation, as well as those associated with the storage of nuclear waste, are widely regarded as solvable. According to proponents of clean coal, oil and gas technologies, as well as the proponents of nuclear technology, it is only a matter of time and resources to find a solution to their waste problems. Similarly, the Australian Government argues that our main efforts need to be concentrated on clean coal technologies, as well as considering the nuclear option. However, when it comes to the challenges associated with renewable energy technologies, like intermittency of wind generated grid power, storage of electricity from renewable energy and so on, there seems to be an attitude amongst Australian energy planners that these challenges represent insurmountable technical and financial problems, and will, at least in the short to medium term, prevent them from becoming a viable alternative to coal, oil, gas and uranium based energy technologies.

Despite a relatively high risk of injury to participants of Australian Rules football, very few players report wearing protective equipment. The aim of this paper is to describe the results of a pilot survey of the attitudes of community-level Australian Rules football players towards protective headgear and the risk of head injury. Seventy players from four purposefully chosen clubs in metropolitan Melbourne completed a self-report questionnaire at the end of the 2000-playing season. Almost all players (91.4%) reported they did not wear protective headgear during the 2000 season. Non-headgear users said that headgear was too uncomfortable (47.4%) and they didn't like it (42.1%). However, 80.0% of non-users said they would wear it if it prevented injury. The major motivation for wearing headgear was to prevent injury. Players considered rugby, boxing and driving a car, to be associated with a higher-risk of head injury than Australian Rules football. As a group, the players perceived the risk of head injury in Australian Rules football to be low to moderate when compared to other sports and activities. This partially explains why so few players wore protective headgear. Repeat surveys on a larger sample should be conducted to further understand the attitudes towards protective headgear and perceptions of risk in community-level Australian football players.

To assess Australian health and medical research (HMR) investment returns by measuring the trends in HMR expenditure and PubMed publications by Australian authors. Bibliometric analysis collating Australian HMR expenditure reported by the Australian Institute of Health and Welfare and Australian HMR publications indexed in PubMed. Similar methods were applied to data from the United Kingdom and New Zealand. From financial year 2000/01 through 2011/12, HMR investment increased by 232% from $1.49 to $4.94 billion (current prices adjusted for inflation), while PubMed publications increased by 123% from 10,696 to 23,818. The average HMR investment required for a single PubMed publication rose by 49% from $139,304 in 2000/01 to $207,364 in 2011/12. Quality analyses showed an increase in systematic reviews, cohort studies and clinical trials, and a decrease in publications in PubMed's core clinical journal collection. Comparisons with New Zealand and the United Kingdom showed that Australia has had the greatest overall percentage increase in gross publication numbers and publications per capita. Our analyses confirm that increased HMR expenditure is associated with an increase in HMR publications in PubMed. Tracking HMR investment outcomes using this method could be useful for future policy and funding decisions at a federal and specific institution level. © 2015 Public Health Association of Australia.

REGULATION OF AUSTRALIAN MEDICAL PROFESSIONALS AND NATIONAL SECURITY: LESSONS FROM THREE CASE STUDIES.

Science.gov (United States)

Faunce, Thomas; McKenna, Michael; Rayner, Johanna; Hawes, Jazmin

2016-03-01

In recent times, Australia's national security concerns have had controversial impacts on regulation of Australian medical practitioners in areas related to immigration detention. This column explores three recent case studies relevant to this issue. The first involves the enactment of the Australian Border Force Act 2015 (Cth), which has a significant impact on the regulation of medical professionals who work with people in immigration detention. The second involves the decision of the High Court of Australia in Plaintiff M68/2015 v Minister for Immigration and Border Protection [2016] HCA 1 that an amendment to Australian federal legislation justified sending children back to immigration detention centres in Papua New Guinea and Nauru. This legislation was previously heavily criticised by the Australian Human Rights Commissioner. The third concerns the deregistration of Tareq Kamleh, an Australian doctor of German-Palestinian heritage who came to public attention on ANZAC Day 2015 with his appearance online in a propaganda video for the Islamic State terrorist organisation al-Dawla al-Islamyia fil Iraq wa'al Sham, also known as Islamic State of Iraq and Syria (ISIS) or Daesh. Australia's professional regulatory system should presumptively respect professional virtues, such as loyalty to the relief of individual patient suffering, when dealing with doctors (whether in Australia or ISIS-occupied Syria) working under regimes whose principles appear inconsistent with those of ethics and human rights.

Full Text Available Abstract Background Indigenous Australians are significantly less likely to participate in colorectal cancer (CRC screening compared to non-Indigenous people. This study aimed to identify important factors influencing the decision to undertake screening using Faecal Occult Blood Testing (FOBT among Indigenous Australians. Very little evidence exists to guide interventions and programmatic approaches for facilitating screening uptake in this population in order to reduce the disparity in colorectal cancer outcomes. Methods Interviewer-administered surveys were carried out with a convenience sample (n = 93 of Indigenous Western Australians between November 2009-March 2010 to assess knowledge, awareness, attitudes and behavioural intent in regard to CRC and CRC screening. Results Awareness and knowledge of CRC and screening were low, although both were significantly associated with exposure to media advertising (p = 0.008; p  Conclusions Improving CRC related knowledge and confidence to carry out the FOBT self-screening test through education and greater promotion of screening has the potential to enhance Indigenous participation in CRC screening. These findings should guide the development of interventions to encourage screening uptake and reduce bowel cancer related deaths among Indigenous Australians.

The ethical commitment of Australian radiographers: Does medical dominance create an influence?

There is a lack of awareness and openness surrounding ethical debate in Diagnostic Radiography literature and culture, perpetuated in part by the historical growth of the technical realm of radiography, radiology and medicine. Hence, the impact of Australian radiographers' current level of professional autonomy, combined with the influence of medical dominance and radiographers' ethical commitment was undocumented. This study investigated the role, importance and attitudes of Australian radiographers towards ethics through a qualitative study following a grounded theory approach. Semi-structured interviews were conducted with 25 Australian. A conceptual framework mapping the causal conditions affecting the ethical commitment was developed. This study argues that a number of internal and external variables weave an intricate fabric of poor identity, subservience and negative workplace culture. Australian radiographers, whist attempting to set a standard of ethical commitment, are hindered by difficulties of medical dominance, relatively poor professional autonomy and difficulty in accepting responsibility. The presence of private radiology enterprise and the association between patient referral and money has eroded the radiographer-patient relationship and introduced the potential for unethical practice in the radiographer-radiologist-referring practitioner relationship

2018-05-01

Full Text Available The fungal genus Wallemia of the order Wallemiales (Wallemiomycotina, Basidiomycota comprises the most xerotolerant, xerophilic and also halophilic species worldwide. Wallemia spp. are found in various osmotically challenged environments, such as dry, salted, or highly sugared foods, dry feed, hypersaline waters of solar salterns, salt crystals, indoor and outdoor air, and agriculture aerosols. Recently, eight species were recognized for the genus Wallemia, among which four are commonly associated with foods: W. sebi, W. mellicola, W. muriae and W. ichthyophaga. To date, only strains of W. sebi, W. mellicola and W. muriae have been reported to be related to human health problems, as either allergological conditions (e.g., farmer’s lung disease or rare subcutaneous/cutaneous infections. Therefore, this allergological and infective potential, together with the toxins that the majority of Wallemia spp. produce even under saline conditions, defines these fungi as filamentous food-borne pathogenic fungi.

A Test of Macromolecular Crystallization in Microgravity: Large, Well-Ordered Insulin Crystals

Crystals of insulin grown in microgravity on space shuttle mission STS-95 were extremely well-ordered and unusually large (many > 2 mm). The physical characteristics of six microgravity and six earth-grown crystals were examined by X-ray analysis employing superfine f slicing and unfocused synchrotron radiation. This experimental setup allowed hundreds of reflections to be precisely examined for each crystal in a short period of time. The microgravity crystals were on average 34 times larger, had 7 times lower mosaicity, had 54 times higher reflection peak heights and diffracted to significantly higher resolution than their earth grown counterparts. A single mosaic domain model could account for reflections in microgravity crystals whereas reflections from earth crystals required a model with multiple mosaic domains. This statistically significant and unbiased characterization indicates that the microgravity environment was useful for the improvement of crystal growth and resultant diffraction quality in insulin crystals and may be similarly useful for macromolecular crystals in general.

Objectives Culture and religion are important in advance care planning (ACP), yet it is not well understood how this is represented in ACP online resources. The aim of the present study was to identify the availability of Australian-based ACP websites and online informational booklets containing cultural and religious information. Methods An environmental scanning framework was used with a Google search conducted from 30 June 2015 to 5 July 2015. Eligible Australian-based ACP websites and online informational booklets were reviewed by two analysts (APS & PM) for information pertaining to at least one culture or religion. Common characteristics were agreed upon and tabulated with narrative description. Results Seven Australian-based ACP websites were identified with varying degrees of cultural and religious information. Seven Australian-based ACP informational booklets were identified addressing culture or religion, namely of Aboriginal and Torres Strait Islander (n=5), Sikh (n=1) and Italian (n=1) communities. Twenty-one other online resources with cultural and religious information were identified, developed within the context of health and palliative care. Conclusions There is no comprehensive Australian-based ACP website or informational booklet supporting ACP across several cultural and religious contexts. Considering Australia's multicultural and multifaith population, such a resource may be beneficial in increasing awareness and uptake of ACP. What is known about the topic? Health professionals and consumers frequently use the Internet to find information. Non-regulation has resulted in the proliferation of ACP online resources (i.e. ACP websites and online informational booklets). Although this has contributed to raising awareness of ACP, the availability of Australian-based ACP online resources with cultural and religious information is not well known. What does this paper add? This paper is the first to use an environmental scanning methodology to identify

To investigate the characteristics of parents and intended parents and their current and planned behaviour in relation to surrogacy arrangements. Members of two Australian parenting support forums who were considering surrogacy or were currently or previously in a surrogacy arrangement were invited to complete an online survey during July 2013. Sociodemographic characteristics; proportions engaging in domestic uncompensated and overseas compensated arrangements; countries used; costs incurred; and impact on behaviour of state laws criminalising compensated surrogacy. Of 1135 potential participants, 312 (27%) commenced the survey. Of these, 24 did not fulfil inclusion criteria and 29 did not complete the survey. Eighty-nine respondents were considering surrogacy and 170 had commenced or completed surrogacy. Many respondents (53%) considered both overseas and domestic surrogacy. Among those who only considered one option, overseas surrogacy was considered significantly more often than domestic surrogacy (92% v 8%; P surrogacy were India and the United States, and average total estimated costs were $69 212 for India and $172 347 for the US. Barriers discouraging domestic surrogacy included concern that the surrogate might keep the child (75%), belief that it was too long and complicated a process (68%) and having no one of the right age or life stage to ask (61%). Few intended parents (9%) were deterred by state laws criminalising compensated surrogacy. Most Australian intended parents via surrogacy consider or use overseas compensated arrangements. Laws banning compensated surrogacy do not appear to deter those seeking surrogacy arrangements.

2011-05-01

Full Text Available Abstract Background Indigenous Australians have an incidence of end stage kidney disease 8-10 times higher than non-Indigenous Australians. The majority of research studies concerning Indigenous Australians have been performed in rural or remote regions, whilst the majority of Indigenous Australians actually live in urban settings. We studied prevalence and factors associated with markers of kidney disease in an urban Indigenous Australian cohort, and compared results with those for the general Australian population. Methods 860 Indigenous adult participants of the Darwin Region Urban Indigenous Diabetes (DRUID Study were assessed for albuminuria (urine albumin-creatinine ratio≥2.5 mg/mmol males, ≥3.5 mg/mmol females and low eGFR (estimated glomular filtration rate 2. Associations between risk factors and kidney disease markers were explored. Comparison was made with the AusDiab cohort (n = 8,936 aged 25-64 years, representative of the general Australian adult population. Results A high prevalence of albuminuria (14.8% was found in DRUID, whilst prevalence of low eGFR was 2.4%. Older age, higher HbA1c, hypertension, higher C-reactive protein and current smoking were independently associated with albuminuria on multiple regression. Low eGFR was independently associated with older age, hypertension, albuminuria and higher triglycerides. Compared to AusDiab participants, DRUID participants had a 3-fold higher adjusted risk of albuminuria but not of low eGFR. Conclusions Given the significant excess of ESKD observed in Indigenous versus non-Indigenous Australians, these findings could suggest either: albuminuria may be a better prognostic marker of kidney disease than low eGFR; that eGFR equations may be inaccurate in the Indigenous population; a less marked differential between Indigenous and non-Indigenous Australians for ESKD rates in urban compared to remote regions; or that differences in the pathophysiology of chronic kidney disease exist

To report mammographic screening practice among Chinese-Australian women, and to examine the relationship between demographic characteristics, acculturation factors (English proficiency and length of stay in Australia), cultural beliefs, and having a mammogram as recommended. Cross-sectional and descriptive. The study was conducted in 2009 in Sydney, Australia. Of 988 Chinese-Australian women over 18 years of age invited to participate in the study, 785 (79%) completed and returned the questionnaire. Of these women, 320 (40.8%) were in the target age range of 50 to 69 years. The Chinese Breast Cancer Screening Beliefs Questionnaire (CBCSB) was used as a data collection instrument. Analysis included descriptive statistics, bivariate analysis using chi-square and t tests, and logistic regression. Of the 320 women in the targeted age range of 50 to 69 years, 238 (74.4%) had a mammogram as recommended biannually. Being married-de facto, in the 60 to 69 age group, and speaking Cantonese at home were positively associated with women's mammographic screening practice. However, no statistically significant differences in acculturation factors and having a mammogram as recommended were found. In terms of CBCSB score, women who had mammograms as recommended had more positive attitudes toward health checkups and perceived fewer barriers to mammographic screening. Effort should be focused on specific subgroups of Chinese-Australian women in order to fully understand the barriers involved in participating in mammographic screening. Nurses can use the findings from the present study to design culturally sensitive breast cancer screening programs to encourage women's participation in mammography. © 2011 Sigma Theta Tau International.

Improving the health and safety of those working in Australian agriculture and fishery industries is a recognized priority area for preventative activities. With Australian agricultural industries being among the nation's most dangerous workplaces, there is a need for action. While there are currently known solutions, their implementation is limited. Influential agents, i.e., people who can influence others, are important for helping engender action to enact solutions into practice. This study examines agents that influence safety behavior either negatively (barriers) or positively (facilitators), in the Australian agriculture and fishery industries. Focus groups were conducted with producers and industry representatives. Thematic analysis identified barriers and facilitators to improve health and safety. These were assessed against the Socioecological Model, which considers the various, and often intersecting, human (intrapersonal, i.e. values and attitudes, peers, familial, and cultural) factors influencing safety behavior. Seven categories of human influences were identified: self, peers, family, intergenerational change, industry agents, government agents, and other. Peers (including direct managers) and family were seen to be direct influencers. Individuals signal to others that safety is valued and important. This is reinforced by experience, skill, attitudes, and behavior. Safety practice knowledge acquisition occurred via the family unit, specific training, industry, or knowledge transfer between industries. Government influence predominately focused on legislation and while the source of this influence is distant, it does influence behavior. There is a need to support comprehensive programs. These should include strengthening relationships via peer-to-peer networking, sharing information about safety initiatives, appropriate legislation, and enhancing leadership of all influencers with regard to safety.

Technologies, Democracy and Digital Citizenship: Examining Australian Policy Intersections and the Implications for School Leadership

Directory of Open Access Journals (Sweden)

Kathryn Moyle

2014-01-01

Full Text Available There are intersections that can occur between the respective peak Australian school education policy agendas. These policies include the use of technologies in classrooms to improve teaching and learning as promoted through the Melbourne Declaration on Educational Goals for Young Australians and the Australian Curriculum; and the implementation of professional standards as outlined in the Australian Professional Standard for Principals and the Australian Professional Standards for Teachers. These policies create expectations of school leaders to bring about change in classrooms and across their schools, often described as bringing about ‘quality teaching’ and ‘school improvement’. These policies indicate that Australian children should develop ‘democratic values’, and that school principals should exercise ‘democratic values’ in their schools. The national approaches to the implementation of these policies however, is largely silent on promoting learning that fosters democracy through education, or about making connections between teaching and learning with technologies, school leadership and living in a democracy. Yet the policies promote these connections and alignments. Furthermore, understanding democratic values, knowing what is a democracy, and being able to use technologies in democratic ways, has to be learned and practiced. Through the lens of the use of technologies to build digital citizenship and to achieve democratic processes and outcomes in schools, these policy complexities are examined in order to consider some of the implications for school leadership.

Full Text Available This paper identifies the systematic risk factors for the Australian stock market by applyingthe cointegration technique of Johansen. In conformity with the finance literature andinvestors’ common intuition, relevant a priori variables are chosen to proxy for Australiansystematic risk factors. The results show that only a few systematic risk factors are dominantfor Australian stock market price movements in the long-run while short-run dynamics are inplace. It is observed that the linear combination of all a priori variables is cointegratedalthough not all variables are significantly influential. The findings show that bank interestrate, corporate profitability, dividend yield, industrial production and, to a lesser extent, globalmarket movements are significantly influencing the Australian stock market returns in thelong-run; while in the short-run it is being adjusted each quarter by its own performance,interest rate and global stock market movements of previous quarter.

The related A genome species of the Oryza genus are the effective gene pool for rice. Here, we report draft genomes for two Australian wild A genome taxa: O. rufipogon-like population, referred to as Taxon A, and O. meridionalis-like population, referred to as Taxon B. These two taxa were sequenced and assembled by integration of short- and long-read next-generation sequencing (NGS) data to create a genomic platform for a wider rice gene pool. Here, we report that, despite the distinct chloroplast genome, the nuclear genome of the Australian Taxon A has a sequence that is much closer to that of domesticated rice (O. sativa) than to the other Australian wild populations. Analysis of 4643 genes in the A genome clade showed that the Australian annual, O. meridionalis, and related perennial taxa have the most divergent (around 3 million years) genome sequences relative to domesticated rice. A test for admixture showed possible introgression into the Australian Taxon A (diverged around 1.6 million years ago) especially from the wild indica/O. nivara clade in Asia. These results demonstrate that northern Australia may be the centre of diversity of the A genome Oryza and suggest the possibility that this might also be the centre of origin of this group and represent an important resource for rice improvement. © 2016 The Authors.

Viewing the proposed South African Business Rescuie Provisions from an Australian Perspective

Directory of Open Access Journals (Sweden)

C Anderson

2008-04-01

Full Text Available This article makes some comparisons between the Australian corporate rescue provisions and those proposed to be adopted in South Africa in the Companies Bill 2007. By so doing it may assist in the debate in South Africa over how the legislation is framed as the experience in Australia may be useful as an indicator of issues to be considered. One of the findings of the comparison is that the aims of the Australian legislation and that proposed in South Africa are almost identical. The article identifies a clear concern in the South African proposals with the position of employees which is not apparent in Australia. On the other hand there appears to be less concern in South Africa with the position of secured creditors than is evident in the Australian provisions. The article also notes that the South African proposals do not divide the procedure clearly into a decision-making stage and the period whilst the company is operating under the rescue plan. The Australian provisions provide for a clear break between a period where the creditors have yet to make a choice about the company’s future and the period once a plan (or deed of company arrangement has been adopted. The article also finds that the South African model of rescue as proposed does cover many similar areas as identified in the Australian legislation. It therefore argues that there are sufficient similarities to suggest that much will be common in the experience if they are adopted into the legislation.

Australian Radiation Protection and Nuclear Safety Act 1998. Act No 133

1999-01-01

A set of legislation consisting of three Acts in the field of radiation protection and nuclear safety was passed by both Houses of Parliament on 10 December 1998 and was proclaimed on 5 February 1999. Act No. 133 - Australian Radiation Protection and Nuclear Safety Act, which is a framework Law, established the Australian Radiation Protection and Nuclear Safety Agency (ARPANSA) as the regulatory body for radiation protection and nuclear safety, in place of the Nuclear Safety Bureau. The Chief Executive Officer of ARPANSA, who is appointed by the Governor-General for a term of up to 5 years, is obliged to submit annual and quarterly reports to the Minister on the operations of the Chief Executive Officer, ARPANSA, the Council, the Radiation Health Committee and the Nuclear Safety Committee. The Council is a consultative body which examines issues relating to radiation protection and nuclear safety and advises the Chief Executive Officer on these issues as well as on the adoption of recommendations, policies and codes. The Radiation Health Committee and the Nuclear Safety Committee are to be established as advisory committees to the Chief Executive Officer or the Council. Both committees should draft national policies, codes and standards in their respective fields and review their effectiveness periodically. The second in this series of legislation, Act No. 134, Australian Radiation Protection and Nuclear Safety (License Charges) Act requires holders of both facility and source licenses to pay an annual charge, to be prescribed by the regulations. The third, Act No. 135 , Australian Radiation Protection and Nuclear Safety (Consequential Amendments) Act repeals those provisions of the 1987 Australian Nuclear Science and Technology Organisation Act which concern the Nuclear Safety Bureau, and the 1978 Environment Protection Act as a whole

The Integrated Marine Observing System (IMOS, www.imos.org.au), an AUD 150 m 7-year project (2007-2013), is a distributed set of equipment and data-information services which, among many applications, 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 which effectively observe and measure the 4-dimensional ocean variability, and the physical and biological response of coastal and shelf seas around Australia. Through a national science rationale IMOS is organized as five regional nodes (Western Australia - WAIMOS, South Australian - SAIMOS, Tasmania - TASIMOS, New SouthWales - NSWIMOS and Queensland - QIMOS) surrounded by an oceanic node (Blue Water and Climate). Operationally IMOS is organized as 11 facilities (Argo Australia, Ships of Opportunity, Southern Ocean Automated Time Series Observations, 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) delivering data. IMOS data is freely available to the public. The data, a combination of near real-time and delayed mode, are made available to researchers through the electronic Marine Information Infrastructure (eMII). eMII utilises the Australian Academic Research Network (AARNET) to support a distributed database on OPeNDAP/THREDDS servers hosted by regional computing centres. IMOS instruments are described through the OGC Specification SensorML and where-ever possible data is in CF compliant netCDF format. Metadata, conforming to standard ISO 19115, is automatically harvested from the netCDF files and the metadata records catalogued in the

The Australian AEC has two research reactors at the Lucas Heights Research Establishment, a 10 HW DIDO class materials testing reactor, HIFAR, and a smaller 100kW reactor MOATA, which was recently upgraded from 10kW power level. Because of the HIFAR being some 20 years old, major renewal and repair programmes are necessary to keep it operational. To enable meeting projected increases in demand for radioisotopes, plans for a new reactor to replace the HIFAR have been made and the design criteria are described in the paper. (author)

Attitudes of Australian and Turkish veterinary faculty toward animal welfare.

Izmirli, Serdar; Phillips, Clive J C

2012-01-01

The attitudes of veterinary faculty toward animal welfare were surveyed in four Australian and three Turkish veterinary schools. The former were considered to be typical of modern Western schools, with a faculty of more than 40% women and a primary focus on companion animals, whereas the latter were considered to represent more traditional veterinary teaching establishments, with a faculty of 88% men and a primary focus on livestock. A total of 116 faculty responded to the survey (42 Australian and 74 Turkish faculty members), for response rates of 30% and 33%, respectively. This survey included demographic questions as well as questions about attitudes toward animal-welfare issues. Women were more concerned than men about animal-welfare issues, especially the use of animals in experiments, zoos, entertainment, and sports and for food and clothing. Total scores demonstrated different concerns among Turkish and Australian faculty. The study demonstrates that the veterinary faculty of these two countries have different concerns for animal welfare, concerns that should be acknowledged in considering the welfare attitudes that students may adopt.

Recreational impacts on the fauna of Australian coastal marine ecosystems.

Science.gov (United States)

Hardiman, Nigel; Burgin, Shelley

2010-11-01

This paper reviews recent research into the ecological impacts of recreation and tourism on coastal marine fauna in Australia. Despite the high and growing importance of water-based recreation to the Australian economy, and the known fragility of many Australian ecosystems, there has been relatively limited research into the effects of marine tourism and recreation, infrastructure and activities, on aquatic resources. In this paper we have reviewed the ecological impacts on fauna that are caused by outdoor recreation (including tourism) in Australian coastal marine ecosystems. We predict that the single most potentially severe impact of recreation may be the introduction and/or dispersal of non-indigenous species of marine organisms by recreational vessels. Such introductions, together with other impacts due to human activities have the potential to increasingly degrade recreation destinations. In response, governments have introduced a wide range of legislative tools (e.g., impact assessment, protected area reservation) to manage the recreational industry. It would appear, however, that these instruments are not always appropriately applied. Copyright 2010 Elsevier Ltd. All rights reserved.

Aboriginal Australians experience higher levels of psychological distress, which may develop from the long-term sequelae of social determinants and adversities in early and mid-life. There is little evidence available on the impact of these on the mental health of older Aboriginal Australians. This study enrolled 336 Aboriginal Australian participants over 60 years from 5 major urban and regional areas in NSW, utilizing a structured interview on social determinants, and life-time history of physical and mental conditions; current psychosocial determinants and mental health. Univariate and multivariate analyses were utilized to examine the link between these determinants and current depressive scores and suicidality. There was a high rate of life-time depression (33.3%), current late-life depression (18.1%), and suicidal ideation (11.1%). Risk factors strongly associated with late-life depression included sleep disturbances, a history of suicidal behaviour, suicidal ideation in late-life and living in a regional location. This study supports certain historical and psychosocial factors predicting later depression in old age, and highlights areas to target for prevention strategies.

The Proposition: Imagining Race, Family and Violence on the Nineteenth-Century Australian Frontier

Catriona Elder

2016-06-01

Full Text Available http://dx.doi.org/10.5007/2175-8026.2016v69n2p165 This article analyses John Hillcoat’s 2005 film The Proposition in relation to a spate of Australian films about violence and the (postcolonial encounter released in the early twenty-first century. Extending on  Felicity Collins and Therese Davis argument that these films can be read in terms of the ways they capture or refract aspects of contemporary race relations in Australia in a post-Mabo, this article analyses how The Proposition reconstructs the trauma of the Australian frontier; how from the perspective of the twenty-first century it worries over the meaning of violence on the Australian frontier. It also explores what has become speakable (and remains unspeakable in the public sphere about the history of the frontier encounter, especially in terms of family and race.  The article argues that The Proposition and other early twenty-first century race relations films can be understood as post-reconciliation films, emerging in a period when Indigenous and non-Indigenous Australians were rethinking ideas of belonging through a prism of post-enmity and forgiveness. Drawing on the theme of violence and intimate relations in the film, this article argues that the challenges to the everyday formulation of Australian history proffered in The Proposition reveal painful and powerful differences amongst Australian citizens’ understanding of who belongs and how they came to belong to the nation. I suggest that by focusing on violence in terms of intimacy, relationships, family and kin, it is possible to see this film presented an opportunity to begin to refigure ideas of belonging.

2008-10-01

This study aimed to elicit and compare the responses of Australian consumers towards New Zealand (NZ) direct-to-consumer-advertisements (DTCA) for prescription medicines and matched pharmaceutical company-sponsored advertisements from Australia. A survey questionnaire was mailed to a random sample of residents in a metropolitan area in NSW. Potential participants were randomised to receive one of four different advertisements: two for weight loss and two for Alzheimer's disease. A total of 413 responses were received and analysed. Participants reported that they were not likely to ask for a prescription from their doctor as a result of seeing any of the advertisements in the study. The Australian disease awareness advertisement that did not refer to a medicinal treatment was perceived as more valuable than the NZ DTCA or other Australian advertisement. Overall, participants found it easier to make sense of the more informational advertisements, and felt that there was insufficient information regarding the disease/condition and treatments in the more emotive and transformational advertisements. While there is concern over potential negative effects of pharmaceutical-sponsored disease awareness advertisements, this study found that Australian consumers perceived an informational advertisement with a list of disease symptoms to be valuable. These findings contribute to debate in New Zealand and Australia regarding DTCA and disease awareness advertising, and have the potential to inform guidelines relevant to the advertising of prescription medicine in each country.

The behavioural response of Australian fur seals to motor boat noise.

Directory of Open Access Journals (Sweden)

Joy S Tripovich

Full Text Available Australian fur seals breed on thirteen islands located in the Bass Strait, Australia. Land access to these islands is restricted, minimising human presence but boat access is still permissible with limitations on approach distances. Thirty-two controlled noise exposure experiments were conducted on breeding Australian fur seals to determine their behavioural response to controlled in-air motor boat noise on Kanowna Island (39°10'S, 146°18'E. Our results show there were significant differences in the seals' behaviour at low (64-70 dB versus high (75-85 dB sound levels, with seals orientating themselves towards or physically moving away from the louder boat noise at three different sound levels. Furthermore, seals responded more aggressively with one another and were more alert when they heard louder boat noise. Australian fur seals demonstrated plasticity in their vocal responses to boat noise with calls being significantly different between the various sound intensities and barks tending to get faster as the boat noise got louder. These results suggest that Australian fur seals on Kanowna Island show behavioural disturbance to high level boat noise. Consequently, it is recommended that an appropriate level of received boat sound emissions at breeding fur seal colonies be below 74 dB and that these findings be taken into account when evaluating appropriate approach distances and speed limits for boats.

To provide information about Australian depression sites and the quality of their content; to identify possible indicators of the quality of site content; and determine the accessibility of Australian depression web sites. Cross-sectional survey of 15 Australian depression web sites. (i) Quality of treatment content (concordance of site information with evidence-based guidelines, number of evidence-based treatments recommended, discussion of other relevant issues, subjective rating of treatment content); (ii) potential quality indicators (conformity with DISCERN criteria, citation of scientific evidence); (iii) accessibility (search engine rank). Mean content quality scores were not high and site accessibility was poor. There was a consistent association between the quality-of-content measures and the DISCERN and scientific accountability scores. Search engine rank was not associated with content quality. The quality of information about depression on Australian websites could be improved. DISCERN may be a useful indicator of website quality, as may scientific accountability. The sites that received the highest quality-of-content ratings were beyondblue, BluePages, CRUfAD and InfraPsych.

There have been many individual phytoplankton datasets collected across Australia since the mid 1900s, but most are unavailable to the research community. We have searched archives, contacted researchers, and scanned the primary and grey literature to collate 3,621,847 records of marine phytoplankton species from Australian waters from 1844 to the present. Many of these are small datasets collected for local questions, but combined they provide over 170 years of data on phytoplankton communities in Australian waters. Units and taxonomy have been standardised, obviously erroneous data removed, and all metadata included. We have lodged this dataset with the Australian Ocean Data Network (http://portal.aodn.org.au/) allowing public access. The Australian Phytoplankton Database will be invaluable for global change studies, as it allows analysis of ecological indicators of climate change and eutrophication (e.g., changes in distribution; diatom:dinoflagellate ratios). In addition, the standardised conversion of abundance records to biomass provides modellers with quantifiable data to initialise and validate ecosystem models of lower marine trophic levels.

Australian public attitudes towards uranium mining and export

International Nuclear Information System (INIS)

Shirvington, P.J.

1987-01-01

The Australian nuclear debate is focused on Australia's role as a uranium supplier, on the risks that this uranium might be diverted to nuclear weapons and on the risks of nuclear weapons generally. The results of a survey which was designed to measure the importance of uranium as an issue and reveal underlying influences and information behind public perceptions are presented. The methods and questions asked are given as well as the results. The results show that Australians are fairly unconcerned about uranium. However, many fear the possible application of civil nuclear technology to nuclear weapons, a fear not recognised or expected by the nuclear industry. The public image of the industry could, and should, be improved by television, films and documentaries to inform the general public about the nuclear industry. (U.K.)

Concussion Incidence and Recurrence in Professional Australian Football Match-Play: A 14-Year Analysis

Nathan Gibbs

2017-01-01

Full Text Available Background. Concussion incidence rates in professional Australian football may be underreported due to the injury classification definition. A myriad of factors contribute to concussion risk; however, there is limited long-term surveillance in Australian football. This study analysed concussion in one Australian football team over an extended period. Method. Match-play concussion injuries in one team (n=116 participants were diagnosed and treated by the team physician over 14 years. Analysis of factors related to concussion including matches played, time of day and season, and return to play provided an insight into occurrence and recurrence rates. Results. 140 concussions were recorded (17.6 per 1000 player match hours. A strong relationship was evident between matches played and concussion incidence (r=0.70 and match conditions did not negatively affect the concussion rate. Whether an athlete returned to play in the same match or suffered a loss-of-consciousness concussion (p=0.84, their ensuing rate of concussion was not affected. Conclusion. Concussion in professional Australian football was related to the number of matches played. Further, neither previous incidence nor loss of consciousness affected future concussion risk. This study provides ecologically valid evidence of the concussion incidence rate in professional Australian football and has implications for the management of athletes sustaining concussion injuries.

Development of the AuScope Australian Earth Observing System

Rawling, T.

2017-12-01

Advances in monitoring technology and significant investment in new national research initiatives, will provide significant new opportunities for delivery of novel geoscience data streams from across the Australian continent over the next decade. The AuScope Australian Earth Observing System (AEOS) is linking field and laboratory infrastructure across Australia to form a national sensor array focusing on the Solid Earth. As such AuScope is working with these programs to deploy observational infrastructure, including MT, passive seismic, and GNSS networks across the entire Australian Continent. Where possible the observational grid will be co-located with strategic basement drilling in areas of shallow cover and tied with national reflection seismic and sampling transects.

Full Text Available Australia’s geographical location (within ‘Asia’—seen as a negative into the twenty-first century when the nation defined itself as culturally and aspirationally linked to the major Euro-American metropolitan cultural centres (the ‘West’—must now be reevaluated. After two hundred years of white settlement and of turning its back on the region in which it is located, some Australian writers are writing texts that illuminate an aspect of Australian literature that is in transition, becoming, by definition, in, of, and with the region as well as in, of, and with present time. Art historian Terry Smith’s theory of the three currents of contemporary art, particularly the third current, suggests a new paradigm, a potential break from modernism, and a different kind of entanglement and interconnection in a world that is witnessing shifts in world power, voluntary and involuntary mass movements of people, and real time global communication technologies. Adrian Snodgrass and David Coyne’s application of hermeneutical theory to the architectural design studio via the metaphor of excursion and return illuminates some imaginative intersections, understandings and energies in three texts by Australian authors—Michelle De Kretser, Chi Vu and Jennifer Mackenzie. In Smith’s terms too, the texts perform original leaps of the imagination in their diversity, freshness, and ability to surprise and invite questions about literature’s potential to stir up prior understandings and invite new ways of being in the present. In terms of Giorgio Agamben’s definition of the contemporary, the three texts bring the reader to a plurality and intercultural connectedness that we have yet to fully recognise and live. They represent a line of flight towards a literary imaginary in Australian writing that is contemporary, locally grounded, but also regionally and globally entangled.

Facial soft tissue thicknesses (FSTT) set important quantitative guides in craniofacial identification, but so far Australian FSTTs have only been published for supine cadavers. This study aimed to use B-mode ultrasound to measure FSTTs in living Australians (N=63 participants; n 1 =52 [x¯=21 years, s=2 years]; and n 2 =11 [x¯=54years, s=13years]) using 14 craniometric landmarks with participants in both upright and supine positions. The multiple pre-existing Australian cadaver investigations (n=7 reporting FSTT means and 6 of these reporting raw datasets) enabled living and cadaveric samples drawn from the same parent population to be compared. By using a non-invasive and safe imaging method (no ionising radiation) repeated measurements could be taken in the in vivo participants to gauge measurement reliability (and compare to pre-existing reliability for cadaver measurements): mean r-TEM=12%; max r-TEM=25%. In terms of changes between upright and supine positions (as measured by B-mode ultrasound) only 2 of 14 measured landmarks had FSTT changes in excess of 1mm. Comparisons of the in vivo ultrasound data to pre-existing needle puncture studies demonstrated that mean B-mode ultrasound measurements were very similar to cadaver values. Contrary to popular thought, but in keeping with the findings of prior meta-analyses, cadaver FSTT data are good proxies to living subjects, at least as measured by ultrasound. To increase sample sizes and triangulate upon ground truth FSTT values, weighted grand means combining all Australian samples were calculated (n range=280-385) and compared to the multi-group 2018 adult T-Tables (max. n=10,333).

Mentha, Ricky; Wakerman, Johne

2009-12-01

In 2004, the Australian Football League Central Australia (AFLCA) implemented the Responsible Alcohol Strategy (RAS), which aimed to decrease alcohol consumption at matches, and to promote healthy lifestyle messages to the youth of Central Australia participating in Australian Rules football. The evaluation adopted a pre- and post-implementation design to monitor a number of performance indicators. The evaluation analysed routinely collected data from AFLCA, its Security Company, Alice Springs Police Department and Alice Springs Hospital; we surveyed AFLCA staff, club officials and umpires; and undertook direct observation at AFLCA events. The volume of alcohol sold at matches decreased. Survey data indicate decreased alcohol related violence, improved spectator behaviour and decreased spectator attendances. Police data suggest declining alcohol-related and violent behaviours, but trends were not statistically significant. Alice Springs Hospital injury admission data indicate a non-significant interaction between year and season effect. In a community context of high alcohol consumption and high rates of interpersonal violence, the strategies implemented were successful in decreasing alcohol consumption and related undesirable behaviours at football games. However, these measures have resulted in unintended consequences: decreased numbers of spectators attending games, decreased canteen sales and falling sponsorship. The decreased revenue has raised serious issues about sustainability of the alcohol intervention, and stimulated discussions with government and others about strategies to maintain this important alcohol reduction policy.

This study examined the serving size and energy content per serving of Australian packaged snack foods and confectionery products. Nutrition Information Panel data for 23 sub-categories of packaged snack foods (n = 3481) were extracted from The George Institute for Global Health's 2013 branded food composition database. Variations in serving size and energy content per serving were examined. Energy contents per serving were compared to recommendations in the Australian Dietary Guidelines. Serving sizes varied within and between snack food categories. Mean energy content per serving varied from 320 kJ to 899 kJ. More energy per serving than the recommended 600 kJ was displayed by 22% (n = 539) of snack foods classified in the Australian Dietary Guidelines as discretionary foods. The recommendation for energy content per serving was exceeded in 60% (n = 635) of snack foods from the Five Food Groups. Only 37% (n = 377) of confectionery products displayed the industry-agreed serving size of 25 g. Energy content per serving of many packaged snack foods do not align with the Australian Dietary Guidelines and the industry agreed serving size has not been taken up widely within the confectionery category. Given the inconsistencies in serving sizes, featuring serving size in front-of-pack information may hinder the objective of a clear and simple nutrition message. Messaging to help consumers make healthier choices should consider the variation in serving sizes on packaged snack foods. Copyright © 2015 Elsevier Ltd. All rights reserved.

A review of life expectancy and infant mortality estimations for Australian Aboriginal people

Science.gov (United States)

2014-01-01

Background Significant variation exists in published Aboriginal mortality and life expectancy (LE) estimates due to differing and evolving methodologies required to correct for inadequate recording of Aboriginality in death data, under-counting of Aboriginal people in population censuses, and unexplained growth in the Aboriginal population attributed to changes in the propensity of individuals to identify as Aboriginal at population censuses. The objective of this paper is to analyse variation in reported Australian Aboriginal mortality in terms of LE and infant mortality rates (IMR), compared with all Australians. Methods Published data for Aboriginal LE and IMR were obtained and analysed for data quality and method of estimation. Trends in reported LE and IMR estimates were assessed and compared with those in the entire Australian population. Results LE estimates derived from different methodologies vary by as much as 7.2 years for the same comparison period. Indirect methods for estimating Aboriginal LE have produced LE estimates sensitive to small changes in underlying assumptions, some of which are subject to circular reasoning. Most indirect methods appear to under-estimate Aboriginal LE. Estimated LE gaps between Aboriginal people and the overall Australian population have varied between 11 and 20 years. Latest mortality estimates, based on linking census and death data, are likely to over-estimate Aboriginal LE. Temporal LE changes by each methodology indicate that Aboriginal LE has improved at rates similar to the Australian population overall. Consequently the gap in LE between Aboriginal people and the total Australian population appears to be unchanged since the early 1980s, and at the end of the first decade of the 21st century remains at least 11–12 years. In contrast, focussing on the 1990–2010 period Aboriginal IMR declined steeply over 2001–08, from more than 12 to around 8 deaths per 1,000 live births, the same level as Australia overall in

This study examined the birth distribution for adolescent (i.e. born in the first part of the classification period for both quartile (P born in the latter part of the selection period for both quartile (P = 0.047) and half-year (P = 0.028) compared to the Australian national population. The selection bias towards relatively older players in adolescent AFL draftees may be related to advanced physical and psychological maturity, and exposure to higher-level coaching compared to their younger counterparts. The reverse RAE in mature age draftees is a novel finding and supports the need for strategies to encourage continued participation pathways for talented Australian football players born later in the selection year.

Full Text Available Kinetic calculation results describing the observed nucleation and growth rates of barium sulphate crystals precipitated in an integrated reaction-crystallization process in a barium sulphate-ammonium chloride-water system are presented and analyzed. The scope of experiments included two continuous model DTM-type crystallizers (Draft Tube Magma with internal circulation of the suspension forced by a liquid jet-pump device responsible for stable and intensive enough ascending/descending flow of BaSO4 crystal magma in a mixing chamber. For comparison purposes the experimental data corresponding to a continuous DT (Draft Tube crystallizer with propeller agitator are presented and discussed. The various types of laboratory crystallizers used were fed with concentrated water solution of barium chloride (of 10 or 24 mass % and - in a stoichiometric proportion - crystalline ammonium sulphate, assuming isothermal (348 K and hydrodynamic (average residence time of suspension in a crystallizer: 900 s process conditions. The observed nucleation and growth rates of barium sulphate crystals were estimated on the basis of crystal size distributions (CSDs using convenient calculation scheme derived for an MSMPR (Mixed Suspension Mixed Product Removal model approach. Considering the experimental population density distribution courses, a size-dependent growth (SDG phenomenon was taken into account in the kinetic calculations. Five SDG kinetic models recommended in the accessible literature were used for kinetic parameter values estimation. It was proved statistically, that Rojkowski’s two SDG models (hyperbolic and exponential best suit for our own experimental data description.

Introduction: Documentation on the history of Australian radiotherapy is limited. This study provides radiation therapists' (RTs) perspectives of the people, workplace, and work practices in Australian radiotherapy centres from 1960 onwards. It provides a follow-up to our previous study: Australian radiation therapy: An overview – Part one, which outlines the history and development of radiotherapy from conception until present day. Methods: Four focus groups were conducted on separate occasions in 2010, one in South Australia and three in Victoria, Australia. Participants who worked in radiotherapy were purposively selected to ensure a range of experience, age, and years of work. Results: From a RT perspective, radiotherapy has evolved from a physically demanding ‘hands-on’ work environment, often with unpleasant sights and smells of disease, to a more technology-driven workplace. Conclusion: Understanding these changes and their subsequent effects on the role of Australian RTs will assist future directions in advanced role development.

To assess Australian adult physicians' views about evidence-based medicine (EBM) and quality improvement (QI). Cross-sectional postal survey of two hundred and forty-four randomly selected Australian physicians (78.5% response rate). Physicians' views about the promotion of EBM and QI and their impact on patient care, strategies to support better clinical practice and self-reported understanding of EBM terms. Sixty-eight per cent (95% confidence interval (CI): 62-74%) of physicians had a positive view of the current promotion of EBM in Australia. Significantly fewer (45%; 95% CI: 38-51%) were so positive about QI (P evidence, significantly fewer (21%; 95% CI: 17-27%) agreed they had sufficient time to do so (P Australian physicians have positive views of EBM, QI appears less well regarded. Initiatives to improve quality and safety that incorporate principles and language of EBM will likely be received better by physicians than isolated QI. Further enhancement of EBM requires concomitant attention to physician training, workplace infrastructure and supportive professional development.

The mouth as a site of structural inequalities; the experience of Aboriginal Australians.

Durey, A; Bessarab, D; Slack-Smith, L

2016-06-01

To address the mouth as a site of structural inequalities looking through the lens of Aboriginal Australian experience. This is a critical review of published literature relevant to our objective. Criteria for selection included articles on: the social context of oral and general health inequalities for Aboriginal Australians; Aboriginal perceptions and meanings of the mouth and experiences of oral health care and the role of the current political-economic climate in promoting or compromising oral health for Aboriginal Australians. Evidence suggests oral health is important for Aboriginal Australians yet constrained by challenges beyond their control as individuals, including accessing dental services. Competing demands on limited budgets often led to oral health dropping off the radar unless there was an emergency. Structural (social, political and economic) factors often inhibited Aboriginal people making optimum health choices to prevent oral disease and access services for treatment. Factors included cost of services, limited education about oral health, intense advertising of sugary drinks and discrimination from service providers. Yet the literature indicates individuals, rather than structural factors, are held responsible and blamed for the poor state of their oral health. The current neoliberal climate focuses on individual responsibility for health and wellbeing often ignoring the social context. To avoid the mouth becoming an ongoing site for structural inequality, critically reviewing oral health policies and practices for whether they promote or compromise Aboriginal Australians' oral health is a step towards accountability-related oral health outcomes.

To examine the potential relationship between sleep duration and efficiency and injury incidence in elite Australian footballers. Prospective cohort study. Australian footballers (n=22) from one AFL club were studied across the 2013 competitive season. In each week sleep duration and efficiency were recorded via actigraphy for 5 nights (the 3 nights preceding a game, the night of the game and the night after the game). Injury incidence was monitored and matched with sleep data: n=9 players suffered an injury that caused them to miss a game. Sleep in the week of the injury (T2) was compared to the average of the previous 2 weeks (T1). A two-way repeated measures ANOVA was used to determine any effect of sleep duration and efficiency on injury. Significance was accepted at psleep duration, sleep efficiency or a combination of these factors. Analysis of individual nights for T2 versus T1 also showed no differences in sleep quality or efficiency. However, a main effect for time was found for sleep duration and efficiency, with these being slightly, but significantly greater (psleep duration and efficiency on injury occurrence was found in elite Australian footballers.

2005-07-01

To date, of the Australian essential oils, only tea tree (Melaleuca alternifolia) and Eucalyptus spp. have undergone extensive investigation. In this study a range of Australian essential oils, including those from Anethole anisata, Callistris glaucophyllia, Melaleuca spp. and Thyptomine calycina, were assayed for in vitro antibacterial activity. M. alternifolia was also included for comparison purposes. Activity was determined using standard disc diffusion assays with each oil assayed at 100%, 10% and 1% against five bacteria (Escherichia coli, Salmonella typhimurium, Staphylococcus aureus, Pseudomonas aeruginosa and Alcaligenes faecalis) and the yeast, Candida albicans. All bacteria, with the exception of Ps. aeruginosa, were susceptible to one or more of the essential oils at 100%, with only Eremophilia mitchelli inhibiting the growth of any bacteria at 1% (inhibition of Sal. typhimurium). Where multiple samples of a single oil variety were tested variability in activity profiles were noted. This suggests that different methods of preparation of essential oils, together with variability in plant chemical profiles has an impact on whether or not the essential oil is of use as an antimicrobial agent. These results show that essential oils from Australian plants may be valuable antimicrobial agents for use alone or incorporated into cosmetics, cleaning agents and pharmaceutical products.

Australian dinosaurs have played a rare but controversial role in the debate surrounding the effect of Gondwanan break-up on Cretaceous dinosaur distribution. Major spatiotemporal gaps in the Gondwanan Cretaceous fossil record, coupled with taxon incompleteness, have hindered research on this effect, especially in Australia. Here we report on two new sauropod specimens from the early Late Cretaceous of Queensland, Australia, that have important implications for Cretaceous dinosaur palaeobiogeography. Savannasaurus elliottorum gen. et sp. nov. comprises one of the most complete Cretaceous sauropod skeletons ever found in Australia, whereas a new specimen of Diamantinasaurus matildae includes the first ever cranial remains of an Australian sauropod. The results of a new phylogenetic analysis, in which both Savannasaurus and Diamantinasaurus are recovered within Titanosauria, were used as the basis for a quantitative palaeobiogeographical analysis of macronarian sauropods. Titanosaurs achieved a worldwide distribution by at least 125 million years ago, suggesting that mid-Cretaceous Australian sauropods represent remnants of clades which were widespread during the Early Cretaceous. These lineages would have entered Australasia via dispersal from South America, presumably across Antarctica. High latitude sauropod dispersal might have been facilitated by Albian–Turonian warming that lifted a palaeoclimatic dispersal barrier between Antarctica and South America. PMID:27763598

Packing constraints and precise placement of functional groups are the reason that organic molecules in the crystalline state often display unusual physical or chemical properties not observed in solution. Here we report a single-crystal-to-single-crystal dimerization of a bromodiacetylene that involves unusually large atom displacements as well as the cleavage and formation of several bonds. Density functional theory computations support a mechanism in which the dimerization is initiated by a [2 + 1] photocycloaddition favoured by the nature of carbon-carbon short contacts in the crystal structure. The reaction proceeded up to the theoretical degree of conversion without loss of crystallinity, and it was also performed on a preparative scale with good yield. Moreover, it represents the first synthetic pathway to (E)-1,2-dibromo-1,2-diethynylethenes, which could serve as synthetic intermediates for the preparation of molecular carbon scaffolds. Our findings both extend the scope of single-crystal-to-single-crystal reactions and highlight their potential as a synthetic tool for complex transformations.

Japanese investment in Australian coal assets through the demise of concessional financing

International Nuclear Information System (INIS)

West, Jason

2013-01-01

The Australian coal industry has been described as being a perpetual case of ‘profitless prosperity’. This implies that foreign companies invest in low-margin mining activities with motives other than profit. It is argued that foreign investors and Japanese trading companies in particular used government investment concessions and subsidies to help create oversupply in the seaborne coal market. The aim of this strategy is to depress contract prices at the cost of achieving reasonable profitability levels, which have historically been well below that of other investors in the Australian mining sector. This study shows that the quasi-integration via concessional funding arrangements is not a credible strategy employed by Japanese trading companies or the Japanese Government. The analysis rejects the hypothesis that via foreign direct investment, Japanese companies are securing coal at below average prices. Furthermore we find no clear evidence of Japanese trading companies using their information advantage as equity investors to secure coal at favourable prices during contract negotiations. Finally we examine the investment behaviour of new entrants in the Australian coal production sector to highlight the differences in investment strategy between Japanese companies and other foreign investors regarding the security of supply. - Highlights: ► Past foreign investment practices sacrificed profit to create oversupply of Australian coal. ► Only a small amount of equity capital was required to exert influence over coal output. ► Foreign investors can no longer exploit information advantages to obtain favourable prices. ► Information advantages from partial ownership do not influence supply costs. ► Foreign investors in Australian mining now achieve similar profits to domestic firms.

Single crystals of 4-Nitrophenol urea have been grown from water using slow evaporation technique at constant temperature, with the vision to improve the properties of the crystals. The unit cell parameters of the grown crystals were determined by single crystal and powder X-Ray diffraction. FTIR studies reveals the presence of different vibrational bands. The Optical studies confirmed that the crystal is transparent up to 360 nm .TGA and DSC studies were carried out to understand the thermal behavior of crystals. The SHG studies show the suitability of the crystals for NLO applications. The etching studies were carried out to study the behavior of the crystals under different conditions.These studies reveal that the crystals of 4-Nitrophenol urea are suitable for device applications. - Highlights: • 4-Nitrophenol urea crystals of dimensions 14 mm × 1 mm were grown. • UV–Visible studies indicate the crystal is transparent in the region of 370–800 nm. • Thermal studies show the crystal starts decomposing at 170 °C. • SHG studies indicate that the crystals have NLO efficiency 3.5 times that of KDP.

2017-10-01

To explore Australian experts' views regarding strengths and gaps in school-leavers' knowledge of nutrition and food systems ( N&FS) and factors that influence that knowledge. Semi-structured interviews were conducted with 21 highly experienced food-related experts in Australia. Qualitative data were analysed thematically using Attride-Stirling's thematic network framework. Two global themes and several organising themes were identified. The first global theme, 'structural curriculum-based problems', emerged from three organising themes of: inconsistencies in provided food education programs at schools in Australia; insufficient coverage of food-related skills and food systems topics in school curricula; and the lack of trained school teachers. The second global theme, 'insufficient levels of school-leavers knowledge of N&FS ', was generated from four organising themes, which together described Australian school-leavers' poor knowledge of N&FS more broadly and knowledge translation problem for everyday practices. Study findings identified key problems relating to current school-based N&FS education programs in Australia and reported knowledge gaps in relation to N&FS among Australian school-leavers. These findings provide important guidance for N&FS curriculum development, to clearly articulate broadly-based N&FS knowledge acquisition in curriculum policy and education documents for Australian schools. © 2017 The Authors.

Gender Gaps in Indigenous Socioeconomic Outcomes: Australian Regional Comparisons and International Possibilities

Directory of Open Access Journals (Sweden)

Nicholas Biddle

2010-07-01

Full Text Available International literature clearly demonstrates the potential for gender-based inequalities to constrain development processes. In the United Nations Development Programme Gender-related Development Index, Australia ranks in the top five across 177 countries, suggesting that the loss of human development due to gender inequality is minor. However, such analysis has not been systematically applied to the Indigenous Australian population, at least in a quantitative sense. Using the 2006 Australian Census, this paper provides an analysis across three dimensions of socioeconomic disparity: Indigeneity, gender, and geography. This paper also explores the development of a similar gender-related index as a tool to enable a relative ranking of the performance of Indigenous males and females at the regional level across a set of socioeconomic outcomes.The initial findings suggest that although there is a substantial development gap between Indigenous and non-Indigenous Australians, the development loss from gender-related inequality for Indigenous Australians is relatively small. Higher life expectancy and education attainment for Indigenous females balances out their slightly lower earnings to a large extent. At the regional level, Indigenous females tend to fare better than Indigenous males for the set of indicators chosen; and, this is particularly true in capital cities.

This paper reports findings from a 2012 online survey of Australian Schools of Nursing and builds on findings of earlier studies. The survey design allowed direct comparison with a previous study from the USA but limited its scope to the pre-registration (pre-service Bachelor of Nursing) curriculum. It also included extra mental health specific questions. Australian patterns of adoption and application of high-fidelity human patient (mannequin) simulation in the pre-registration nursing curriculum share features with experiences reported in previous US and Australian surveys. A finding of interest in this survey was a small number of Schools of Nursing that reported no current use of high-fidelity human patient (mannequin) simulation and no plans to adopt it, in spite of a governmental capital funding support programme. In-line with prior surveys, mental health applications were meagre. There is an absence of clearly articulated learning theory underpinnings in the use of high-fidelity human patient (mannequin) simulation generally. It appears the first stage of implementation of high-fidelity human patient (mannequin) simulation into the pre-registration nursing curriculum has occurred and the adoption of this pedagogy is entering a new phase.

Full Text Available This paper looks at the Australian author, traveller, conservationist and Buddhist Marie Byles (1900-1979 as “eastern” and Australian at once. It investigates the influence of Buddhist spirituality and travel on her approach to the environment and explores some possibilities arising from looking at her work as part of a broader transnational humanitarian and intellectual identification, moving beyond ethnicity based boundaries. Thinking about eastern Australian identities can encourage consideration of Australia in Asia, Australia as Asian, connections across seas, and links and differences within Australia. The paper explores Marie Byles as an eastern Australian by considering her travel in Sydney and the region (in Australia, China, Vietnam, India and Burma from the 1930s to the 1960s, the design and use of her home as a hub for early Buddhist meetings, her publication of texts discussing Eastern philosophy, and her environmental activism. Throughout the discussion Byles’s understanding of power relations, derived from an entwining of feminist and socialist ideas, a pacifist and Buddhist/spiritualist revaluation of environments emerges. From these influences she provided challenges to her fellow walkers, environmentalists, and society at large to rethink relationships with nature and each other, insights that have yet to be adequately explored and recognised.

The arrangements for the maintenance of the Australian standards for {sup 60}Co are described in detail. The primary standards are a graphite cavity chamber for exposure/air kerma and a graphite calorimeter for absorbed dose. These secondary standards are described and their responses in corresponding {sup 90}Sr reference sources are reported. Accurate ratios between the Australian Radiation Laboratory (ARL) and Australian Nuclear Science and Technology (ANSTO) {sup 90}Sr reference sources are derived for use in future calibrations. The value of 28.8 years for the half-life of {sup 90}Sr is confirmed. The usefulness of {sup 90}Sr reference source measurements in quality assurance is discussed. The charge sensitivity and linearity of the ANSTO electrometers are reported by two different methods and are compared with previous results. Calibration factors for all the secondary standard ionization chambers are given, in terms of exposure, air kerma and absorbed dose to water. Calibration factors are also given for most of the chambers in terms of absorbed dose to graphite. The methods of deriving the calibration factors are explained in detail, including all the corrections applied to both the primary and secondary standard measurements. Three alternative methods of deriving the absorbed dose to water calibration factors are compared. The reported calibration factors are compared with previous results. Changes in the Australian units of exposure, air kerma and absorbed dose to graphite and water are derived from changes in the corresponding calibration factors. The Australian units of exposure and air kerma have not changed significantly since 1990. The Australian unit of absorbed dose to graphite is now 1.1 % smaller than in 1993 and 1.3 % smaller than in 1990. The Australian unit of absorbed dose to water is now 1.4 % smaller than in 1993, but is only 0.9 % smaller than in 1990.

Rupture of the anterior cruciate ligament (ACL) is a common and debilitating injury that impacts significantly on knee function and risks the development of degenerative arthritis. The outcome of ACL surgery is not monitored in Australia. The optimal treatment is unknown. Consequently, the identification of best practice in treating ACL is crucial to the development of improved outcomes. The Australian Knee Society (AKS) asked the Australian Orthopaedic Association (AOA) to consider establishing a national ACL registry. As a first step, a pilot study was undertaken by the Australian Orthopaedic Association National Joint Replacement Registry (AOANJRR) to test the hypothesis that collecting the required information in the Australian setting was possible. Surgeons completed an operative form which provided comprehensive information on the surgery undertaken. Patients provided pre- and post-operative questionnaires including the Knee Injury and Osteoarthritis Outcome Score (KOOS) and the Marx Activity Scale (MA Scale). The number of ACL procedures undertaken at each hospital during the recruitment period was compared against State Government Health Department separation data. A total of 802 patients were recruited from October 2011 to January 2013. The overall capture rate for surgeon-derived data was 99%, and the capture rate for the pre-operative patient questionnaire was 97.9%. At 6 months, patient-reported outcomes were obtained from 55% of patients, and 58.5% of patients at 12 months. When checked against State Government Health Department separation data, 31.3% of procedures undertaken at each study hospital were captured in the study. It is possible to collect surgeon-derived and pre-operative patient-reported data, following ACL reconstruction in Australia. The need to gain patient consent was a limiting factor to participation. When patients did consent to participate in the study, we were able to capture nearly 100% of surgical procedures. Patient consent

Many nonlinear optical (NLO) crystals have been identified as potential candidates in optical and electro-optical devices. Use of NLO organic crystals is expected in photonic applications. Hence organic nonlinear optical materials have been intensely investigated due to their potentially high nonlinearities, and rapid response in electro-optic effect compared to inorganic NLO materials. There are many methods to grow organic crystals such as vapor growth method, melt growth method and solution growth method. Out of these methods, solution growth method is useful in providing constraint free crystal. Single crystals of Dopamine have been grown by evaporating the solvents from aqueous solution. Crystals obtained were of the size of orders of mm. The crystal structure of dopamine was determined using XRD technique. Images of crystals were obtained using FEG SEM Quanta Series under high vacuum and low KV.

Australia will be developing a significant financial asset portfolio in the %u2018Future Fund%u2019 to smooth the financing of expenses through time. This raises the significant policy question of how best to manage the government balance sheet to reduce risk. This paper provides a framework for optimal balance sh...

Parity violation and parity conservation in unstirred crystallization: Effect of first crystals

Statistics of nucleation of chiral forms was studied to establish the effect of the number of first crystals and their handedness on distributions of enantiomers. Various bimodal, trimodal and unimodal distributions are obtained in unstirred crystallization, depending on the number of initial crystals and growth conditions. The binomial distribution satisfactorily describes experimental distributions of enantiomeric excess and may be used to predict distributions and probabilities of nucleation of enantiomers. The first nucleated crystals determine the handedness of secondary crystals, and number of initial crystals governs statistics of chiral nucleation. According to the binomial distribution if single crystals nucleate as the first, the bimodal distributions result with D and L peaks. If LD, LL, and DD pairs are nucleated as first, trimodal distributions with D, R, and L peaks are created, and if groups of crystals of various handedness nucleate as the first the unimodal distributions of enantiomeric excess with racemate R peaks are formed. Chiral nucleation experiments on sodium bromate were the basis for the theoretical considerations and verifications of predictions resulting from binomial distributions on probabilities of the creation of L and D crystals, and racemates, and the presence of D, L, and R peaks in the distributions. Growth conditions affect the number of the first crystals and effectiveness of cloning, and as a result, the distributions of enantiomers. Formation of pure enantiomers and/or racemates proves that the conservation of chiral symmetry, and the breakage of chiral symmetry can occur in unstirred crystallization.

National cancer survival statistics are available for the total Australian population but not Indigenous Australians, although their cancer mortality rates are known to be higher than those of other Australians. We aimed to validate analysis methods and report cancer survival rates for Indigenous Australians as the basis for regular national reporting. We used national cancer registrations data to calculate all-cancer and site-specific relative survival for Indigenous Australians (compared with non-Indigenous Australians) diagnosed in 2001-2005. Because of limited availability of Indigenous life tables, we validated and used cause-specific survival (rather than relative survival) for proportional hazards regression to analyze time trends and regional variation in all-cancer survival between 1991 and 2005. Survival was lower for Indigenous than non-Indigenous Australians for all cancers combined and for many cancer sites. The excess mortality of Indigenous people with cancer was restricted to the first three years after diagnosis, and greatest in the first year. Survival was lower for rural and remote than urban residents; this disparity was much greater for Indigenous people. Survival improved between 1991 and 2005 for non-Indigenous people (mortality decreased by 28%), but to a much lesser extent for Indigenous people (11%) and only for those in remote areas; cancer survival did not improve for urban Indigenous residents. Cancer survival is lower for Indigenous than other Australians, for all cancers combined and many individual cancer sites, although more accurate recording of Indigenous status by cancer registers is required before the extent of this disadvantage can be known with certainty. Cancer care for Indigenous Australians needs to be considerably improved; cancer diagnosis, treatment, and support services need to be redesigned specifically to be accessible and acceptable to Indigenous people.
