Hendrie, Delia, and Duncan Boldy. "Hospital services and casemix in Western Australia." Australian Health Review 25, no. 1 (2002): 173. http://dx.doi.org/10.1071/ah020173.
Full textAbstract:
The Health Department of WA currently operates as a single integrated funder and purchaser of health services for the State. Health Service Agreements defining the level of health provision are negotiated with the various health services in WA. During the latter part of the 1990s, the funding of public hospitals for acute inpatient care moved away froma historical basis to output-based funding using a casemix approach based on Diagnosis Related Groups (DRGs).Other hospital services are still mainly purchased using historical funding levels, negotiated block funding or bedday payments, with output-based funding mechanisms under investigation. WA has developed its own approach toclassifying admitted patients that recognises differences in complexity of care among episodes grouped to the same DRG. WA also has a unique cost estimation model for calculating DRG cost weights, which is based on a linear estimate of the relationship between nights of stay in hospital and the cost of hospital care for each DRG. Another emerging trendin the provision of public hospital services in WA has been the greater involvement of the private sector through the contracting of private providers to operate public hospitals. While no close examination has been undertaken of the outcomes of these changes in terms of their effect on efficiency or other relevant indicators of hospital performance,current purchasing arrangements are being reviewed following recommendations made in a report by the HealthAdministrative Review Committee. No decision has yet been made as to future changes to the funding policy of WA public hospitals.

Full textAbstract:
The Western Australia (WA) State Barrier Fence stretches 2,023 miles (3,256 kilometres) and divides Australia's largest state. The original 'Rabbit Proof Fence' fence was built from 1901–1907 to stop the westbound expansion of rabbits into the existing and potential agricultural zone of Western Australia. Starting as a seemingly straightforward, albeit costly, solution to protect what was considered a productive landscape, the fence failed to keep out the rabbits. It was subsequently amended, upgraded, re-named and used to serve different purposes: as Vermin Fence and State Barrier Fence (unofficially also Emu Fence or Dog Fence) the fence was designed to exclude native Australian animals such as emus, kangaroos and dingoes. In the Australian 'boom and bust' environment, characterised by extreme temperatures and unpredictable rainfall, interrupting species movement has severe negative impacts on biodiversity – an issue aggravated by the fact that Australia leads in global extinction rates (Woinarski, Burbidge and Harrison, 2015). The twentieth century history of the fence demonstrates the agrarian settlers' struggle with the novelty and otherness of Western Australia's ecological conditions – and severe lack of knowledge thereof. While the strenuous construction, expensive maintenance and doubtful performance of the fence provided useful and early environmental lessons, they seem largely forgotten in contemporary Australia. The WA government recently commenced a controversial $11 million project to extend the State Barrier Fence for another 660 kilometres to reach the Esperance coast, targeting dingoes, emus and kangaroos – once again jeopardising habitat connectivity. This paper examines the environmental history, purposes and impacts of the State Barrier fence, critically discusses the problems associated with European farming and pastoralism in WA, and touches on alternative land-use perspectives and futures.

Full textAbstract:
Context The primary selective forces responsible for shaping life-history traits come from the physical and biological environment in which a species resides. Consequently, the limits of a species range may provide a useful measure of adaptive potential to environmental change. The proximity of foraging grounds to terrestrial nursing habitat constrains central-place foragers such as otariid seals in selecting breeding locations. The Australian sea lion (Neophoca cinerea) is an endangered otariid endemic to Australia, whose northern-range extent occurs at a temperate–tropical transition zone on the western coast of Western Australia (WA). Aims Currently, there is a complete absence of data on the foraging ecology of Australian sea lions in WA. We sought to address this critical knowledge gap and provide data on the foraging ecology of adult female Australian sea lions at three isolated breeding colonies in western WA. Methods We used stable-isotope ratios of carbon (δ13C) and nitrogen (δ15N) in the whiskers of pups as proxies to characterise feeding behaviour of 10–28% of all adult female Australian sea lions at each colony. We then compared these geographic data to (1) conspecifics at similar latitude in South Australia (SA) and (2) isotopic data collated from other studies on seabirds that inhabit the region, to place foraging behaviour of adult female Australian sea lions into context. Key results At the southernmost colonies in WA, individual animals were members of one of two distinct isotopic clusters that could be described by differences in δ15N and δ13C values. Individuals at the northernmost colony displayed δ15N values similar to those of seabirds in the same region. Across the study, isotope ratios of adult female Australian sea lions in western WA were between 3‰ and 5‰ lower than those observed at a colony at similar latitude in SA. Conclusions Gross differences in the physical oceanography between WA and SA may in part explain the differences in isotope ratios of individuals between the regions, with lower δ15N and δ13C values in WA probably reflecting the relatively depauperate conditions of the Leeuwin Current. Implications Potential regional differences in trophic structure should be considered when developing appropriate management plans for Australian sea lions and regional variation in the diet of Australian sea lion warrants further investigation.

Full textAbstract:
AbstractThe Western Australian Twin Register (WATR) was established in 1997 to study the health of all child multiples born in Western Australia (WA). The Register has until recently consisted of all multiples born in WA between 1980 and 1997. Using unique record linkage capacities available through the WA data linkage system, we have subsequently been able to identify all multiple births born in WA since 1974. New affiliations with the Australian Twin Registry and the WA Institute for Medical Research are further enabled by the use of the WA Genetic Epidemiology Resource — a high-end bioinformatics infrastructure that allows efficient management of health datasets and facilitates collaborative research capabilities. In addition to this infrastructure, funding provided by these institutions has allowed the extension of the WATR to include a greater number of WA multiples, including those born between 1974 and 1979, and from 1998 onwards. These resources are in the process of being enabled for national and international access.

Full textAbstract:
Dengue virus (DENV) and chikungunya virus (DENV) are arboviruses of major public health importance. Monitoring circulation of medically important mosquito-borne viruses in the Indo Pacific region allows countries to predict disease outbreaks and prepare mitigation and control strategies. We have monitored long-term molecular epidemiology of DENV and CHIKV in Indonesia and Western Australia (WA), with febrile Western Australian travellers returning from Indonesia as sentinels. Our findings provide insights into the transmission dynamics of CHIKV genotypes and DENV serotypes, genotypes and lineages in the region and virus importation to WA. Our ongoing studies provide valuable and timely information on transmission of emerging and re-emerging arboviruses in the Indo Pacific region and furthermore provide detailed genomic data that inform our understanding of viral and epidemic virulence.

Full textAbstract:
BackgroundRheumatoid arthritis (RA) is a heterogeneous chronic autoimmune disease that affects the synovial joint lining and may result in permanent joint destruction, premature death, and socio-economic burden.1 Although RA is one of Australia’s national health priority areas and gathering information about the RA burden of disease was one of the national action plans2, no published epidemiological study adequately describes RA prevalence and risk factors for frequent hospitalisations in Western Australia (WA) to date. An accurate prevalence estimate of this disease offers a framework for predicting present and growing healthcare service requirements in the future.3ObjectivesWe estimated RA period prevalence and identified risk factors of frequent RA hospitalisations, using linked administrative health and state-specific Australian Pharmaceutical Benefits Scheme (PBS) datasets in WA from 1995–2014.MethodsRA prevalence was calculated per 1000 hospital separations and biological therapy users. RA patients were identified in the WA linked health dataset using ICD codes 714.0–714.9 and M05.00–M06.99. Dispensing data on biological therapy for RA were obtained from PBS records and converted to defined daily doses/1000 population/day. Multivariate logistic regression was used to analyse risk factors for frequent RA hospitalisations (>2/year), controlling for sex, age, and geographic locations.ResultsA total of 17,125 RA patients were admitted to WA hospitals between 1995–2014. The total number of RA hospital separations was 50,353, averaging three hospitalisations per patient over 20 years. The RA period prevalence was 3.4 per 1,000 separations (0.34%), while the RA period prevalence based on biological therapy use was 0.36%. The corrected RA prevalence based on biological therapy usage was 0.36% and 0.72% for the 2005–2009 and 2010–2014 periods, respectively (Table 1). Female gender, age 60–69 years, and living in rural areas were all risk factors for frequent RA hospitalisations.Table 1.Total number of Rheumatoid Arthritis patients in Western Australia taking a standard dose daily (DDD) of RA biological therapy from 1995 to 2014.YearTotal RA bDMARDs utilisation (DDD/1000 population/day)WA general populationPrevalence of RA bDMARDs use in WA population (%)Number of RA patients use standard dose daily of bDMARDs at WA20030.011,952,7410.001420040.081,979,5420.0115820050.162,011,2070.0232920060.232,050,5810.0247620070.312,106,1390.0364320080.502,171,7000.051,09420090.602,240,2500.061,33820100.592,290,8450.061,36120110.632,353,4090.061,47520120.772,425,5070.081,85920130.662,486,9440.071,64920141.002,517,6080.102,510Abbreviations: bDMARDs, biologic disease-modifying anti-rheumatic drugs included Abatacept, Adalimumab, Certolizumab, Etanercept, Golimumab, Infliximab, Rituximab, Tocilizumab; DDD, defined daily doses; RA, Rheumatoid arthritis; WA, Western Australia.ConclusionBased on hospital and biological therapy data, the minimal prevalence of RA in Western Australia is 0.34–0.36%, which falls within the literature range. Older female RA patients in rural areas were more likely to be hospitalised, suggesting unmet needs in primary care access.References[1] Guo Q, Wang Y, Xu D, Nossent J, Pavlos NJ, Xu J.

Full textAbstract:
AbstractThis paper presents the findings of the first stage of research on the impact of the Australian Sustainable Schools Initiative (AuSSI) at an independent primary school in Western Australia. A longitudinal (20 year) case study is being conducted, utilising data related to Education for Sustainability (EfS) at the school from 1990-2009. 2005 was a critical year for the school because it marked the beginning of participation in the Sustainable Schools Initiative pilot in Western Australia (AuSSI-WA). The research investigates elements of EfS in operation at the school pre- and post- AuSSI-WA, as well as student and teacher outcomes after involvement in the Initiative. An analysis of the initial data suggests that participation in AuSSI-WA enabled the school to engage with a growing commitment to EfS in the context of a whole - school approach.

Full textAbstract:
There are 491 Western Australian (WA) basidiomycete macrofungi, most of which are found also in eastern Australia (78.4%) or overseas. Only 52 (10.6%) endemic WA species have been identified. Of the 32 WA endemics known from more than one location, most (25) have ranges greater than 100 km, even though they are usually represented by few collections (average 4.2). It is considered likely that further collecting will extend ranges. Only Torrendia grandis and T. inculta are known from several collections from the one restricted area, in the Kellerberrin district. Otherwise there is no conclusive evidence for short-range endemism or for any particular centres of narrow endemism for macrofungi. This also appears to be the case for eastern Australia, with the only exceptions being a few fungi of very narrow host range or very specific substratum requirements. Where sufficient collections are available to determine distribution, most Australian macrofungi seem to be very widespread. A model to explain the lack of short-range endemism in macrofungi will need to draw on detailed knowledge of the phylogeny and population genetics of macrofungi, which is currently lacking. The absence of short-range endemic macrofungi also necessitates reconsideration of conservation strategies for macrofungi, since such species are prime candidates for listing on conservation schedules.

Full textAbstract:
Production of shale gas in the US has changed its position from a gas importer to a potential gas exporter. This has stimulated exploration for shale-gas resources in WA. The search started with Woodada Deep–1 (2010) and Arrowsmith–2 (2011) in the Perth Basin to evaluate the shale-gas potential of the Permian Carynginia Formation and the Triassic Kockatea Shale, and Nicolay–1 (2011) in the Canning Basin to evaluate the shale-gas potential of the Ordovician Goldwyer Formation. Estimated total shale-gas potential for these formations is about 288 trillion cubic feet (Tcf). Other petroleum source rocks include the Devonian Gogo and Lower Carboniferous Laurel formations of the Canning Basin, the Lower Permian Wooramel and Byro groups of the onshore Carnarvon Basin, and the Neoproterozoic shales of the Officer Basin. The Canning and Perth basins are producing petroleum, whereas the onshore Carnarvon and Officer basins are not producing, but they have indications for petroleum source rocks, generation, and migration from geochemistry data. Exploration is at a very early stage, and more work is needed to estimate the shale-gas potential of all source rocks and to verify estimated resources. Exploration for shale gas in WA will benefit from new drilling and production techniques and technologies developed during the past 15 years in the US, where more than 102,000 successful gas production wells have been drilled. WA shale-gas plays are stratigraphically and geochemically comparable to producing plays in the Upper Ordovician Utica Shale, Middle Devonian Marcellus Shale and Upper Devonian Bakken Formation, Upper Mississippian Barnett Shale, Upper Jurassic Haynesville-Bossier formations, and Upper Cretaceous Eagle Ford Shale of the US. WA is vastly under-explored and emerging self-sourcing shale plays have revived onshore exploration in the Canning, Carnarvon, and Perth basins.

Full textAbstract:
Satellite images as well as data collected in situ were used to follow the seasonal changes of the Leeuwin Current south of Western Australia (WA) in 1986-87. The current has two major sources: salty subtropical water from west of WA, and fresher tropical water from north of WA. In summer, the tropical waters are excluded by the strong equatorward wind stress. In autumn and winter, this wind stress is reduced and tropical waters flood southward to dominate the flow. Nevertheless, salty subtropical water is entrained en route, and so, whatever the season, the Leeuwin Current is more saline than the 'local' subantarctic waters off southern WA. From a research vessel, observations were made on the current and one of its offshoots in June 1987. The Leeuwin Current had a maximum surface speed of more than 1 m s-1 just beyond the shelf edge. Its warm, low-salinity surface core rode on a sheath of higher-salinity subtropical water that it had entrained upstream. The first survey of the offshoot showed it to be 50 km across and 130 m deep (for water warmer than 17�C), and it extended 200 km seaward (as deduced from a satellite image). Velocities in the offshoot ranged up to 1 m s-1 southward and 1 m s-1 north-eastward on the western and eastern sides, respectively. Richardson numbers were, in places, as low as 0.25. On a second survey two days later, the offshoot was found to have pinched off and the remnant bulge on the edge of the parent stream to have moved 30 km eastward. The flow around this bulge reached 1.6 m s-'. The offshoot/bulge was possibly first formed in April, and it kept its identity at least until August. During this time, it moved eastward at speeds between 2 and 15 km day-1. In June, the offshoot was estimated to contain water equivalent to five days' transport of the parent current.

Full textAbstract:
In 2018–2019, 85% of discarded plastics were landfilled in Australia. In Western Australia (WA), only 5.6% of plastics were recovered for reprocessing. With several Asian Countries imposing import restrictions, which were the prime destination for recyclables from Australia, the whole scenario for the waste industry has changed. Australia has now adopted export bans for recyclables, including plastics. WA is at a fork in the road; WA needs to rethink its relationship with plastic materials. This study explores how to create local markets for recycled plastics underpinning circular principles. The study examines barriers and drivers to enable markets for recycled plastics in WA through questionnaires, surveys, and interviews with relevant stakeholders. Poor source separation, low and inconsistent plastic waste feedstock, and virgin plastic competition are some of the challenges, while new investments in recycling infrastructure, WA’s take-back scheme for beverage containers and circularity frameworks are drivers. This study concludes that a modulated fee-based product stewardship model focused on product design, along with strategies such as green procurement and landfill management modifications would promote a circular plastic waste economy in WA. This can create markets for secondary recycled plastics, minimize the over-reliance on fossil fuels and prevent plastics from leaking into ecosystems.

Full textAbstract:
Geographically, Western Australia (WA) is one of the largest and most sparsely populated single jurisdictions in the world. Although much of the work of Community Corrections Officers (CCO) in metropolitan Perth is easily recognizable to offender managers in England and Wales, the state’s Indigenous citizens, many living in remote communities, are hugely over-represented in its prisons and pose particular challenges in respect of community supervision. The de-professionalization of CCO training and their supposed inter-changeability with prison officers led to a service that was in danger of ‘losing its way’ and whose performance was comparing unfavourably with that of other Australian states. This article traces the recent history of the post-Mahoney Report Department of Corrective Services, culminating in a return to the title of ‘Probation and Parole’, and asks whether the lessons learned in WA following this re-professionalizing process might be relevant to other jurisdictions.

Background:Rheumatoid arthritis (RA) represents a substantial burden on patients and society in terms of morbidity, enduring disability, and medical expenses (1). RA prevalence is poorly described in Australia, and linked health datasets can provide a more meaningful picture for RA epidemiology in the Australian population.Objectives:To describe the period prevalence rate of RA patients per 1000 hospital separations coded as RA primary or secondary diagnosis in Western Australia (WA) hospitals between 1995 and 2014.Methods:We extracted data on all patients identified in the WA Hospital Morbidity Data Collection between 1995 and 2014, with the International Classification of Diseases (ICD) codes for RA (ICD 10 M05.00–M06.99, and the corresponding ICD 9 codes). We estimated period prevalence rates per 1000 hospital separations and annual average percentage changes, with the total number of hospital separations each year.Results:A total of 17,125 patients were admitted to WA hospitals with a diagnostic code for RA over the study period (1995-2014). The total number of hospital separations for RA patients was 50,353, indicating an average of three hospital separations per patient over twenty years. The RA prevalence was 3.4 per 1000 separations over the study period, with a -2.89% annual average decrease since 1995.Conclusion:These data demonstrate that hospitalisation for RA has decreased considerably in WA over the last two decades. As this decrease roughly coincides with the introduction of biological drug treatment for RA, the reduced need for hospital admission is likely due to improvements in RA management.References:[1]Uhlig T, Moe RH, Kvien TK (2014) The burden of disease in rheumatoid arthritis.

Full textAbstract:
Introduction: In Australia, men who have sex with men (MSM) constitute the majority of newly diagnosed HIV cases. After a decline in the late 1990's, several Australian states have reported increases in HIV mainly attributed to MSM. There has also been an increase in HIV in Western Australia (WA), however recently, a larger proportion have been attributed to people who acquired the infection through heterosexual contact. Objective: This paper describes the epidemiology of HIV in WA from 2000 to 2006, focusing on the increase in cases with heterosexual exposure. Methods: In WA, notification of HIV cases is mandatory for doctors and laboratories. Information collected includes basic demographics and probable exposure. Descriptive analysis was carried out on de-identified HIV notification data from 2000 to 2006. Results: An annual average of 49 HIV cases were notified in 2000-2004. However, in 2005 and 2006, this increased to 64 and 72 cases respectively. The increase was mainly among non-Aboriginal males and females reporting heterosexual contact. The number of non-Aboriginal males who reported heterosexual contact increased from an average of 9 cases in 2000-2004 to an average of 20 cases in 2005-2006. The number of non-Aboriginal female cases reporting heterosexual exposure increased from an average of seven cases in 2000-2004 to 9 and 14 cases notified in 2005 and 2006 respectively. The majority of non-Aboriginal males reporting heterosexual exposure in 2005-2006 acquired their infection overseas (84%). Of these, 71% reported Asia as the place of acquisition. Of the non-Aboriginal females reporting heterosexual exposure in 2005-2006, 52% were acquired overseas. The number of Aboriginal cases remained stable between 2000 and 2006 fluctuating between 2 and 11 cases and continued to be mainly heterosexually acquired within WA. Conclusion: There has been an increase in the number of male and female HIV cases reporting heterosexual exposure in WA. A large proportion reported acquiring their infection overseas highlighting the need to raise awareness among people who travel, work in countries with high rates of HIV.

The Australian Pharmaceutical Benefits Scheme (PBS) has subsidised biological disease-modifying anti-rheumatic drugs (B-DMARDs) since 2003 [2].Objectives:We examined the impact of B-DMARDs availability on RA hospitalisation rate in the Western Australia (WA) population pre- and post- B-DMARDs introduction to the PBS (1995-2002 and 2003-2014).Methods:Population PBS dispensing data for WA of DMARD were obtained and converted to defined daily doses (DDD)/1000 population/day using the WA population census. RA inpatient records were extracted from the WA Hospital Morbidity Data Collection using ICD-9 codes 714 and ICD-10 codes M05.00–M06.99). Principal component analysis (PCA) was applied to determine the relationship between DMARDs use and RA hospital admission rates.Results:There was a total of 17,125 patients who had 50,353 admissions with a diagnostic code for RA during the study period. DMARD use for RA rose from 1.45 to 3.19 DDD/1000 population/day over 1995-2014 (Figure 1). In 1995-2002, the number of RA admissions fell from 7.9 to 2.6 per 1000 hospital separations, then dropped further from 2.9 to 1.9 per 1000 hospital separations in 2003-2014. Based on PCA analysis, conventional DMARDs (methotrexate) and B-DMARDs dispensing had an inverse association with hospital admissions for RA.Conclusion:The increased availability of conventional and biological DMARDs for RA was associated with a significant decline in hospital admissions for RA patients in WA.References:[1]Boonen A, Severens JL (2011) The burden of illness of rheumatoid arthritis.

Full textAbstract:
Phytophthora spp. are recognised as important plant pathogens. Ten new and genetically diverse species, not previously reported from elsewhere, have recently been described from natural ecosystems in Western Australia (WA): Phytophthora multivora1; P. elongata; P. thermophila, P. gregata, P. gibbosa, P. litoralis; P. arenaria, P. constricta; P. fluvialis; and P. amnicola. They were identified by DNA sequencing of recent and historical isolates from the WA Department of Environment and Conservation (DEC). Several additional new taxa await description. New records for WA of at least eight other Phytophthora taxa that are known overseas, some of them as yet undescribed, have also been confirmed: P. inundata; P. taxon niederhauserii, P. taxon asparagi, P. taxon PgChlamydo, P. taxon personii; P. taxon salixsoil; P. palmivora and P. rosacearum. Furthermore, numerous Phytophthora hybrids have been identified in natural vegetation and waterways in WA. The phylogenetic relationships of the new WA Phytophthora taxa, with their nearest relatives, are shown in Figure 1.

Full textAbstract:
Background: There has been a recent increase in the number of heterosexually acquired HIV infections among non-Aboriginal people in Western Australia (WA), which has not been reported in other Australian jurisdictions. This report describes the epidemiological features of this increase. Methods: A descriptive analysis was conducted of newly diagnosed HIV infections among non-Aboriginal WA residents notified to the Department of Health from 2002 to 2006. Analysis outcomes included demographics, exposure categories, and place of HIV acquisition. Results: From 2002 to 2006, 258 new HIV diagnoses were notified among non-Aboriginal WA residents. Over this period, the number of notifications increased from 41 cases in 2002 (2.2 cases/100 000 population) to 66 cases in 2006 (3.4 cases/100 000 population). Overall, 107 (42%) of the cases were heterosexually acquired, and the annual number increased threefold from 2002 to 2006 (12 to 36 cases, respectively). Of these cases, 64 (60%) were male and 43 (40%) were female. The majority (89%) of male cases acquired HIV overseas, mostly in countries other than their region of birth; South-east Asia was the most common place of acquisition reported. Over half (56%) of the female cases acquired HIV overseas, mainly in their region of birth (83%), and sub-Saharan Africa was the most common place of acquisition. Conclusion: There has been a recent increase in heterosexually acquired HIV infections among male and female WA residents, many of whom reported acquiring HIV overseas. Safe sex campaigns in WA should continue to reinforce safe sex messages among people travelling overseas.

Full textAbstract:
Random surveys conducted in the Western Australian (WA) grain belt have shown that herbicide-resistant Lolium rigidum and Raphanus raphanistrum are a widespread problem across the cropping region. In 2010, a random survey was conducted to establish the levels of herbicide resistance for common weed species in crop fields, including the minor but emerging weeds Bromus and Hordeum spp. This is the first random survey in WA to establish the frequency of herbicide resistance in these species. For the annual grass weed Bromus, 91 populations were collected, indicating that this species was present in >20% of fields. Nearly all populations were susceptible to the commonly used herbicides tested in this study; however, a small number of populations (13%) displayed resistance to the acetolactate synthase-inhibiting sulfonylurea herbicides. Only one population displayed resistance to the acetyl-coenzyme A carboxylase-inhibiting herbicides. Forty-seven Hordeum populations were collected from 10% of fields, with most populations being susceptible to all herbicides tested. Of the Hordeum populations, 8% were resistant to the sulfonylurea herbicide sulfosulfuron, some with cross-resistance to the imidazolinone herbicides. No resistance was found to glyphosate or paraquat, although resistance to these herbicides has been documented elsewhere in Australia for Hordeum spp. (Victoria) and Bromus spp. (Victoria, South Australia and WA).

Full textAbstract:
Keynote paper presented at the International Leucaena Conference, 1‒3 November 2018, Brisbane, Queensland, Australia.There is considerable interest from Western Australian (WA) pastoralists on the potential role of leucaena (Leucaena leucocephala) in northern WA, where the potential area for dryland production of species of the genus Leucaena is high. Although it is highly regarded for animal production in other countries and in Queensland, leucaena is a contentious species since its status as an environmental weed precludes it from use on pastoral leases in the Kimberley and Pilbara regions of WA. Development of sterile/seedless forms would overcome risks of spread of the species as a weed. The key environmental constraints to growth of leucaena are likely to be the length of the dry season and low fertility of most soils other than the grey/black cracking clays (vertosols). Psyllid resistance and cool temperature tolerance are likely to be of secondary importance. Opportunities for irrigated production are also emerging and may allow leucaena species to be used in environments previously considered well outside their home-range. It is desirable now to re-examine the diversity of the wider leucaena genus for adaptation to WA conditions generally and for the purpose of selecting elite parent material for use in a sterile/seedless leucaena breeding program. These perennial species that can be under production for 30 to 40 years need to be evaluated in the target environments for at least 3‒5 years to fully understand their potential as adult plants.

Full textAbstract:
Objectives To describe the epidemiology of congenital and infectious syphilis during 1991–2009, examine the impact of public health interventions and discuss the feasibility of syphilis elimination among Aboriginal people in Western Australia (WA). Methods: WA congenital and infectious syphilis notification data in 1991–2009 and national infectious syphilis notification data in 2005–2009 were analysed by Aboriginality, region of residence, and demographic and behavioural characteristics. Syphilis public health interventions in WA from 1991–2009 were also reviewed. Results: During 1991–2009, there were six notifications of congenital syphilis (50% Aboriginal) and 1441 infectious syphilis notifications (61% Aboriginal). During 1991–2005, 88% of notifications were Aboriginal, with several outbreaks identified in remote WA. During 2006–2009, 62% of notifications were non-Aboriginal, with an outbreak in metropolitan men who have sex with men. The Aboriginal : non-Aboriginal rate ratio decreased from 173 : 1 (1991–2005) to 15 : 1 (2006–2009). Conclusions: These data demonstrate that although the epidemiology of syphilis in WA has changed over time, the infection has remained endemic among Aboriginal people in non-metropolitan areas. Given the continued public health interventions targeted at this population, the limited success in eliminating syphilis in the United States and the unique geographical and socioeconomic features of WA, the elimination of syphilis seems unlikely in this state.

Full textAbstract:
In eastern Australia, there have been several as yet unconfirmed reports of Wheat mosaic virus (WMoV) infecting wheat (3). WMoV, previously known as High plains virus (HPV), is transmitted by the wheat curl mite (WCM, Aceria tosichella). It is often found in mixed infections with Wheat streak mosaic virus (WSMV), also transmitted by WCM (2,3). WSMV was first identified in Australia in 2003 (3). In October 2012, stunted wheat plants with severe yellow leaf streaking were common in a field experiment near Corrigin in Western Australia consisting of nine wheat cultivars. These symptoms were also common in two commercial crops of wheat cv. Mace near Kulin. Leaf samples (one per plant) from each location were tested by ELISA using specific antiserum to WMoV (syn. HPV 17200, Agdia, Elkhart, IN). At the field experiment, 20 leaf samples were collected at random from each wheat plot (4 replicates) and tested individually by ELISA. WMoV incidence was 5% for cv. Yipti, 16% for cvs Emu Rock, Wyalkatchem and Mace, 22% for cvs. Corack, Fortune, Calingiri, and Magenta, and 55% for cv. Cobra. From the two commercial wheat crops, 100 leaf samples were collected at random from each and tested by ELISA. WMoV incidence was 2 and 4%. In addition, 50 leaf samples of Hordeum leporinum (barley grass) and 20 of Lolium rigidum (annual ryegrass) were collected and tested by ELISA. WMoV incidence was 2% in H. leporinum, but 0% in L. rigidum. Infected H. leporinum plants were symptomless. Symptomatic wheat leaf samples from both sites were tested by RT-PCR using WMoV specific primers designed from its RNA3 sequence (1). The PCR products (339 bp) were sequenced and lodged in GenBank (Accession Nos KC337341 and KC337342). WMoV isolates from Corrigin (WA-CG12) and Kulin (WA-KU12) had identical sequences. When the nucleic acid sequences of WA-CG12 and WA-KU12 were compared with those of the three other WMoV isolates on GenBank, they had 100% nucleotide sequence identity with a Nebraska isolate (U60141), and 99.7% identity to two United States sweet corn isolates (AY836524 and AY836525). Ten symptomatic wheat plants were collected from each location, transplanted into pots and leaf samples tested individually for WMoV and WSMV (07048, Loewe, Germany) by ELISA. All were infected with both viruses and infested with WCM. WCM-infested glumes (>10 WCM/glume) were placed on the leaf sheaths of 60 wheat plants cv. Calingiri (35 with WA-CG12 and 25 with WA-KU12) and 13 sweet corn plants cv. Snow Gold (WA-CG12 only). In addition, 20 wheat and 10 sweet corn plants were left without infested glumes to be uninoculated controls. All 60 WCM-inoculated wheat plants became stunted with severe leaf streaking. When leaf samples from each plant were tested by ELISA 18 to 30 days later, both viruses were detected. WMoV was detected in all 13 WCM-inoculated sweet corn plants and WSMV in two of them. Plants with WMoV alone initially had short chlorotic leaf streaks that subsequently combined, causing broad streaks. These are typical WMoV symptoms for sweet corn (1). No symptoms developed and no virus was detected in any of the uninoculated wheat or sweet corn control plants. The WMoV nucleotide sequence obtained from an infected sweet corn plant was identical to those of WA-CG12 and WA-KU12. To our knowledge, this is the first confirmed report of WMoV presence in Australia. References: (1) B. S. M. Lebas et al. Plant Dis. 89:1103, 2005. (2) D. Navia et al. Exp. Appl. Acarol. 59:95, 2013.

Full textAbstract:
Purpose Offsite construction approaches and methodologies have been proffered a potential solution for controlling “traditional” projects, especially where high levels of complexity and uncertainty exist. Given this, locations such as Western Australia (WA), where there are unique housing provision challenges, offsite construction method was considered a potential solution for not only addressing the complexity/uncertainty challenges but also alleviating the housing shortage. However, whilst acknowledging the benefits of offsite construction, recognition was also noted on perceived barriers to its implementation, primarily relating to cost uncertainty. This recognition is exacerbated by very limited offsite construction cost data and information available in the public domain. In response to this, this paper sims to provide detailed cost analysis of three offsite construction projects in WA. Design/methodology/approach To hold parameters constant and facilitate cross-case comparative analysis, data were collected from three embedded case studies from three residential housing projects in WA. These projects represent the most contemporary implementation of offsite in WA; where two were completed in 2016/2017 and the third project was still ongoing during the data collection of this research. The research methodological approach and accompanying data analysis component engaged a variety of techniques, which was supported by archival study of project data and evidence gathered from the offsite construction provider. Findings Core findings revealed three emerging themes from residential offsite construction projects pertinent to cost. Specifically, the overall cost of delivering residential housing project with offsite construction techniques, the cost variability of offsite construction residential housing projects as impacted by uncertainties and the cash flow of residential offsite construction projects based on the payment term. These three major cost drivers are elucidated in this paper. Originality/value This research presents new cost insights to complement the wider adoption of offsite construction techniques. It presents additional information to address the limited cost data and information of offsite construction projects available in the public domain particularly for residential housing projects (within the bounded context of WA). It also highlights the further stages needed to enhance data validity, cognisant of universal generalisability and repeatability, market maturity and stakeholder supply chains.

Full textAbstract:
Western Australia (WA) was one of the first states in Australia to deploy medical team members to the tsunami-stricken regions of the Maldives and Banda Aceh in 2004. This early experience led the WA Department of Health to develop and pilot these teams locally and to progress a national model for their future development, which could be implemented further by other Australian jurisdictions. Further experience with these teams in Yogyakarta after the 2006 Java earthquake, Karratha after Tropical Cyclone George in 2007, Ashmore Reef after the 2009 boat explosion, Samoa after the 2009 tsunami, and during the Pakistan floods in 2010 have signaled both the utility of the Australian Medical Assistance Teams (AUSMATs) and the commitment by the Australian Commonwealth and State Governments to utilize these teams in both domestic and international settings. This presentation will examine the implementation of the AUSMAT model in Australia over the last five years, the modifications to the original model to suit the unique geographical and resource challenges faced by Australian teams, both within and outside Australia, and the lessons learned from recent team deployments. The challenges of delivering health care over vast, sparsely populated distances, and the inherent and increasing natural and industrial disaster threats in the Asia-Pacific region, have contributed to the modification of the model to ensure that the AUSMATs are flexible, modular, and capable of responding to a variety of major incidents. The national model continues to evolve to ensure that well prepared, equipped and trained civilian AUSMATS remain able to effectively deploy to a mass casualty situation in Australia's area of interest.

Full textAbstract:
This paper analyses the WA legal framework that regulates the impact of shale and tight gas project development, especially during the extended appraisal phase. It assesses whether the existing regulatory framework in WA is more suited to conventional petroleum projects, particularly regarding the application of the Environmental Plan requirements, and triggers for referral to the Environmental Protection Authority (EPA) during the extended appraisal phase of project development. This paper not only seeks to understand whether the existing framework is suited to the commercial development of shale and tight gas resources in WA, it also provides information and points of discussion for industry and regulators so that there might be a consensus in the development of shale and tight gas (especially during the field appraisal and development phase) in the existing WA regulatory framework, and the development of shale gas resources in Australia generally. The paper initially considers the existing regulatory framework of shale and tight gas activities in WA, including an examination of the Western Australian Department of Mines and Petroleum as the lead agency in the development of unconventional gas resources. It also assesses whether the existing regulatory framework for shale and tight gas activities in WA is best practice for the appraisal phase of shale and tight gas activities.

Full textAbstract:
Dental Health Services (DHS) is the largest public primary oral healthcare provider in WA. The objective of this study was to calculate probable distance patients are expected to travel to the nearest clinic, gauge utilisation rates and predict the direction of likely changes in future demand for subsidised dental care. Eligible population data was collected from the Department of Human Services and the Australian Bureau of Statistics websites and integrated with the waiting list and the recall list data provided by the DHS. In total, 65% of the eligible WA population are residing in the metropolitan area; however, only 19% of those are either on the waiting list or have already received subsidised care. In all, 35% of the total eligible WA population are residing in country areas. A total of 30% of the eligible country WA patients are located within a 100-km range of a Government Dental Clinic, with only 11% of those either on the waiting list or having already received subsidised dental care. Country WA residents are at a significant disadvantage by comparison to their metropolitan counterparts. Eligible WA country residents are up to 40% less likely to receive treatment when compared to the metropolitan residents.

Full textAbstract:
In the present paper, we review 4 topics that were identified through extensive consultation with stakeholders as issues of high impact and influence for the grains industry: improving soil testing and interpretation; role of fluid fertilisers in the Western Australian (WA) grains industry; using spatial and temporal information to improve crop nutrient management, particularly for nitrogen; and developing recommendations for managing emerging nutrient deficiencies. The key findings are summarised below. To further improve soil testing and interpretation, the review suggests that future research should focus on addressing soil sampling and interpretation questions, as they are important factors affecting the accuracy of fertiliser recommendations with changing cropping practices. There have been several studies to compare fluid with granular forms of P in WA, but the responses have not, so far, been consistent. More work may be needed to understand different crop response to fluid P fertiliser additions, particularly on low pH soils in WA. An understanding of the long-term performance of fluid P will also require an assessment of the residual value of fluid P compared with granular P under field conditions. Precision agriculture (PA) technology has potential to improve crop nutrient management and farm profitability in WA. The review indicates that understanding both spatial and temporal yield variation is critical for the successful adoption of PA technology by growers. The review also suggests that in WA, there is a need to explore the use of different layers of spatial information for determining management zones. In response to wide adoption of no-till and stubble retention cropping systems, increased use of fluid fertilisers together with advanced application technologies, and increased interest in cropping in the high rainfall zone, there is need to better understand growers’ practices and attitudes to crop nitrogen (N) management, and thus to better position research and extension activities. The review also suggests the need to evaluate new fertiliser products and site-specific N management concepts and develop N management practices for waterlogging-prone soils for improved N use efficiency in cereal production systems in WA. The negative balance of magnesium (Mg) observed in WA cropping systems, together with the information reviewed on factors affecting soil Mg content and crop response to Mg application across Australia, suggests that there is a need to evaluate the risk and impact of Mg deficiency on acidic sandy soils of WA.

Full textAbstract:
Constitutional systems of Westminster heritage are increasingly moving towards fixed-term parliaments to, amongst other things, prevent the Premier or Prime Minister opportunistically calling a ‘snap election’. Amongst the Australian states, qualified fixed-term parliaments currently exist in New South Wales, South Australia and Victoria. Queensland, Tasmania and Western Australia have also deliberated over whether to establish similar fixed-term parliaments. However, manner and form provisions in those states' constitutions entrench the Parliament's duration, Governor's Office and dissolution power. In Western Australia and Queensland, unlike Tasmania, such provisions are doubly entrenched. This article considers whether these entrenching provisions present legal obstacles to constitutional amendments establishing fixed-term parliaments in those two states. This involves examining whether laws fixing parliamentary terms fall within section 6 of the Australia Acts 1986 (Cth) & (UK). The article concludes by examining recent amendments to the Electoral Act 1907 (WA) designed to enable fixed election dates in Western Australia without requiring a successful referendum.

Full textAbstract:
The South West Hub Carbon Capture and Storage Project (SWH), managed by the WA Department of Mines and Petroleum (WA DMP), is evaluating the potential for a commercial-scale carbon storage site near major emissions sites in southwest WA. The area under investigation is in the southern Perth Basin, focusing on a 150 km2 area in the shires of Harvey and Waroona. WA DMP is conducting a major feasibility study and collecting pre-competitive data in partnership with the local community. The activities are done in a stage-gate model to obtain relevant information on the potential storage capacity, containment security and injectivity of the geology. Following a smaller 2D seismic survey and the drilling of the Harvey–1 stratigraphic well, a more complex 3D seismic survey was undertaken in February to March, 2014. These activities have confirmed the potential for commercial-scale CO2 storage. A new work package has been initiated with the drilling of three wells (Harvey–2, –3 and –4) underway and plans to drill a fifth well in the next 12 months. The stage-gate approach has been cost-effective, resulting in a carefully planned data acquisition and research program. The approach allows new results, information and potential future activities to be rolled out to stakeholders and the community in the area.

Full textAbstract:
Larval production and recruitment underpin the maintenance of coral populations, but these early life history stages are vulnerable to extreme variation in physical conditions. Environmental managers aim to minimise human impacts during significant periods of larval production and recruitment on reefs, but doing so requires knowledge of the modes and timing of coral reproduction. Most corals are hermaphroditic or gonochoric, with a brooding or broadcast spawning mode of reproduction. Brooding corals are a significant component of some reefs and produce larvae over consecutive months. Broadcast spawning corals are more common and display considerable variation in their patterns of spawning among reefs. Highly synchronous spawning can occur on reefs around Australia, particularly on the Great Barrier Reef. On Australia’s remote north-west coast there have been fewer studies of coral reproduction. The recent industrial expansion into these regions has facilitated research, but the associated data are often contained within confidential reports. Here we combine information in this grey-literature with that available publicly to update our knowledge of coral reproduction in WA, for tens of thousands of corals and hundreds of species from over a dozen reefs spanning 20° of latitude. We identified broad patterns in coral reproduction, but more detailed insights were hindered by biased sampling; most studies focused on species ofAcroporasampled over a few months at several reefs. Within the existing data, there was a latitudinal gradient in spawning activity among seasons, with mass spawning during autumn occurring on all reefs (but the temperate south-west). Participation in a smaller, multi-specific spawning during spring decreased from approximately one quarter of corals on the Kimberley Oceanic reefs to little participation at Ningaloo. Within these seasons, spawning was concentrated in March and/or April, and October and/or November, depending on the timing of the full moon. The timing of the full moon determined whether spawning was split over two months, which was common on tropical reefs. There were few data available for non-Acroporacorals, which may have different patterns of reproduction. For example, the massivePoritesseemed to spawn through spring to autumn on Kimberley Oceanic reefs and during summer in the Pilbara region, where other common corals (e.g.Turbinaria&Pavona) also displayed different patterns of reproduction to theAcropora. The brooding corals (Isopora&Seriatopora) on Kimberley Oceanic reefs appeared to planulate during many months, possibly with peaks from spring to autumn; a similar pattern is likely on other WA reefs. Gaps in knowledge were also due to the difficulty in identifying species and issues with methodology. We briefly discuss some of these issues and suggest an approach to quantifying variation in reproductive output throughout a year.

Full textAbstract:
Bovine anaemia caused by Theileria orientalis group (BATOG) causes significant production and economic losses in Australia’s cattle industry. The pathogenic T. orientalis genotypes reported in Australian cattle are type 1 (Chitose) and type 2 (Ikeda). The present study aimed to determine the prevalence and distribution of T. orientalis genotypes in adult lactating cows in Western Australia (WA) dairy herds. A total of 100 whole blood samples from lactating cows from 10 farms were obtained and screened for T. orientalis using polymerase chain reaction (PCR). Sanger sequencing was subsequently used to characterise T. orientalis genotypes isolated from positive samples. A total of thirteen cows (13%; 95% CI: 7.1–21.2%) were positive for T. orientalis, and six out of ten farms (60%; 95% CI: 26.2–87.8%) housed at least one T. orientalis-positive cow. The distribution of T. orientalis was found to be wide and dense in the South west region of WA and the southern coast of WA. The predominant T. orientalis genotype identified was Ikeda (n = 11, 11%; 95% CI: 5.6–18.8%), while the Buffeli genotype was identified in WA for the first time, albeit at a low prevalence (n = 1, 1%; 95% CI: 0.0–5.4%). This study has provided useful epidemiological evidence on the prevalence and distribution of T. orientalis in adult lactating dairy cows in WA dairy farms, and on the importance of conducting widespread surveillance programs for the understanding of BATOG in WA.

Full textAbstract:
Purpose – The purpose of this paper is to record Visual Arts education in Western Australia (WA) as it underwent significant change between 1967 and 1987, in administration, policy, curriculum and professional development. Design/methodology/approach – A narrative inquiry approach was utilized to produce a collective recount of primary Visual Arts teacher education, based on 17 interviews with significant advocates and contributors to WA Visual Arts education during the aforementioned period. Findings – This paper underscores the history of the role of Western Australian Superintendents of Art and Crafts and the emergence of Visual Arts specialist teachers in primary schools, from the successful establishment of a specialist secondary Visual Arts program at Applecross Senior High School, to the mentoring of generalist primary teachers into a specialist role, as well as the development and implementation of a new Kindergarten through to Year 7 Art and Crafts Syllabus. It also discusses the disestablishment of the WA Education Department’s Art and Crafts Branch (1987). Originality/value – The history of primary Visual Arts specialists and advocacy for Visual Arts in WA has not been previously recorded. This history demonstrates the high quality of past Visual Arts education in WA, and questions current trends in pre-service teacher education and Visual Arts education in primary schools.

Full textAbstract:
Background:The incidence of Septic arthritis (SA) in adults is rising, but few data are available for children (1). SA symptomatology in young children is often atypical and delayed diagnosis can cause significant morbidity.Objectives:To describe the incidence, risk factors and long-term outcomes in children hospitalised with septic arthritis (SA) in Western Australia (WA).Methods:We extracted population-based longitudinally linked administrative health data for patients under 16 years with a first inpatient primary or secondary code of 711.xx (ICD9-CM) and M00.xx (ICD10-AM) in WA for the study period 1990-2010 (to allow a minimum 5 year followup). We report annual incidence rates per 100.000 (AIR), prior conditions during lookback (median 15 months, IQR 5-45) as well as joint and other comorbidities including Charlson comorbidity index (CCI) and standardised mortality rates (SMR) during a median follow-up of 10 years. Age and gender speficic population and mortality rate data were obtained from the Australian Bureau of Statistics.Results:A total of 891 patients (62% male, median age 6.4 (IQR 1.9-10.6) years with 34% <3 years of age) had a first admission for SA. AIR was 9.85 (CI 4.79-14.41) overall with higher rates in males (11.9 vs 7, p<0.01) and no apparent period (Figure 1) or seasonal variation. Knees (43.9%), hips (34.6%), and ankles (13.3%) were most frequently affected with Staphylococci (49%) the predominant organism in patients with positive cultures (41.5%). Prior infections (40.4%) and respiratory disease (7 %) were the main preexisting morbidities. Mean hospital stay was 5.78 (± 6.4) days with ICU admission required in 1.9%, while 30-day readmittance rate was 10.4%. During follow-up 25 patients (3%) had recurrent/persistent osteomyelitis, nine patients were diagnosed with osteoarthrosis (1.1%) and five patients (0.6%) underwent joint replacement. More female patients developed new comorbidity (CCI>0, 34.6 vs 27.2%, p=0.02) including diabetes (4.2% vs 0%, p=0.001), cardiovascular events (4.2 vs 1.4%, p=0.002) and chronic arthritis (1% vs 0, p=0.05). While the crude mortality rate was low (0.3%) SMR was significantly increased for female patients (10.52, CI 1.59-41.6).Conclusion:The statewide incidence of septic arthritis in children in WA is similar to a recent report (1) and did not change over a 20-year period. In this large population based study, subsequent bone/joint disease occured in 4.6 %, while a third of patients developed other comorbidity before the age of 18. Such (subclinical) comorbidity may thus be a contributing factor to SA development and to the increased mortality risk in female SA patients.References:[1]Cohen E, Katz T, Rahamim E, Bulkowstein S, Weisel Y, Leibovitz R, Fruchtman Y, Leibovitz E.

Full textAbstract:
On-site wastewater treatment systems (OWTS) are widely used in Western Australia (WA) to treat and dispose of household wastewater in areas where centralized sewerage systems are unavailable. Septic tanks, aerobic treatment units (ATUs), and composting toilets with greywater systems are among the most well established and commonly used OWTS. However, there are concerns that some OWTS installed in WA are either performing below expected standards or failing. Poorly performing OWTS are often attributed to inadequate installation, inadequate maintenance, poor public awareness, insufficient local authority resources, ongoing wastewater management issues, or inadequate adoption of standards, procedures, and guidelines. This paper is to review the installations and failures of OWTS in WA. Recommendations to the Department of Health Western Australia (DOHWA) and Local Government (LG) in regard to management strategies and institutional arrangements of OWTS are also highlighted.

Full textAbstract:
The Western Australian Department of Transport (DoT) is the hazard management agency (HMA) for marine oil pollution in Western Australia (WA). DoT initiated the WA marine oil pollution risk assessment (WAMOPRA), a detailed assessment of oil spill risk in Western Australian State waters. It comprised two components. The first component evaluated protection priorities of the receiving environment to assess potential consequences of marine oil pollution. The second component assessed the likelihood, size, location and type of marine oil pollution. Protection priority outputs from component one were modelled with spill risk from component two, to give an overall risk profile for the State. For management purposes, State waters were divided into seven zones and smaller shoreline cells (~10 km × ~20 km). Geospatial datasets representing the various receptors identified were collated and grouped into the following five categories: Protected fauna; Protection areas; Cultural heritage; Economic; and Social, amenity and recreation. Using a multi-criteria analysis approach, the spatial data layers for each receptor identified were assigned a ranking from one (very low priority) to five (very high priority) for protection. The effects of both floating and dissolved hydrocarbons were ranked. These rankings were then used to produce a map showing very low to very high priorities of the shoreline cells for each category. The outcome of this project is the largest single assessment of protection priorities (~13000 km of coastline), undertaken across a highly variable coastline, using a standard and repeatable approach that can be applied across Australia.

Purpose Off-site manufacturing (OSM) application in vertically higher and spatially larger projects within Western Australian (WA) commercial sector has demonstrated the potential of benefitting from such a construction technique, but introducing a new methodology to a traditional sector such as commercial sector is not always straightforward. The acceptance of the new methodology, level of awareness of the stakeholders involved and the readiness of the supply chain to deliver, for instance, may influence the success of its implementation. Given the infancy of such methodology in the WA construction industry, this research project aims to analyse factors influencing the implementation of OSM construction method in WA. Design/methodology/approach Following a thorough literature review, an existing research agenda in OSM was used to inform the direction of this research, i.e. focussing on external macro aspects of the decision making to implement OSM. Three projects in WA were studied, and the data collection was facilitated through archival study and semi-structured interviews with construction practitioners who were the stakeholders of the three projects. Data analysis was conducted through content analysis to draw the findings and conclusion of this research. Findings The analysis of the studied cases revealed relevant economic/financial, technological and regulatory factors, as well as social factors influencing the implementation of OSM, particularly in WA commercial projects. These findings were then used to develop an overall understanding of the external macro factors influencing decision making in implementing OSM that forms a formal research agenda aimed at enabling successful implementation of OSM in WA construction industry, particularly in its commercial sector. Originality/value The research findings presented in this paper identified factors that significantly influence the implementation of such alternative technology in a traditional sector. These factors were then structured to form the subsequent research agenda to continuously pursue the implementation of OSM in the sector. While the research agenda takes into account the unique characteristics of the WA construction industry, it contributes to the global and the Australian national research agenda, and the research methodology reported in this paper can be used to develop similar research agenda elsewhere.

Full textAbstract:
The taxonomy of Australian Isoodon bandicoots has changed continuously over the last 20 years, with recent genetic studies indicating discordance of phylogeographic units with current taxonomic boundaries. Uncertainty over species relationships within southern and western Isoodon, encompassing I. obesulus, I. auratus, and I. fusciventer, has been ongoing and hampered by limited sampling in studies to date. Identification of taxonomic units remains a high priority, as all are threatened to varying extents by ongoing habitat loss and feral predation. To aid diagnosis of conservation units, we increased representative sampling of I. auratus and I. fusciventer from Western Australia (WA) and investigated genetic relationships of these with I. obesulus from South Australia (SA) and Victoria (Vic) using microsatellite markers and mitochondrial DNA. mtDNA analysis identified three major clades concordant with I. obesulus (Vic), I. auratus, and I. fusciventer; however, I. obesulus from SA was polyphyletic to WA taxa, complicating taxonomic inference. Microsatellite data aided identification of evolutionarily significant units consistent with existing taxonomy, with the exception of SA I. obesulus. Further, analyses indicated SA and Vic I. obesulus have low diversity, and these populations may require more conservation efforts than others to reduce further loss of genetic diversity.

Full textAbstract:
The COVID-19 pandemic tested the health system of Western Australia (WA) and the relatively new overarching legislative framework that guided the state-wide public health response to the pandemic. This study aimed to evaluate the experiences and roles of environmental health officers (EHOs) in WA during the management of COVID-19 and to identify any policy changes that are needed to facilitate the rapid deployment of EHOs during a future public health crisis. An online survey with 78 respondents was administered and analysis was both qualitative and quantitative. It was found that participants believed there was inadequate resourcing, workforce shortages, increased workloads, and a lack of recognition and integration of the profession within the COVID-19 response. Notably, more than 65% of the respondents believed they could have been better utilised during the pandemic. This research has demonstrated that the COVID-19 pandemic in WA had clear gaps in its processes for managing responses and resilience to pandemics. Policy recommendations outlining a more efficient and integrated delivery of environmental health services throughout the state during emergencies are discussed.

AbstractThis research was commissioned by the (then) Department of Environment and Conservation (DEC) to provide recommendations on how to best support Western Australian (WA) secondary schools to engage in education for sustainability (EfS). The research aims were to identify barriers and benefits to being involved in EfS, the support systems required for schools to participate in EfS at secondary school level, and the difficulties that secondary schools experience when implementing EfS programs. A variety of research methods were utilised: semi-structured interviews with non-teaching stakeholders; online questionnaires for teachers, school administrators and students; focus groups and semi-structured interviews with teachers and school administrators; and an expert panel workshop to discuss data and recommendations prior to completion of a final report. Data were collected from 29 schools, 45 teachers and school administrators, 186 students, and various EfS external providers and stakeholders across metropolitan and regional WA. This article focuses on three issues identified in the data that we consider important and under-represented in discourses of EfS in Australia: lack of understanding about what EfS means among educators; lack of meaningful student involvement in EfS in secondary schools; and differing quality in EfS programs offered by external providers. We conclude this article by offering ways to improve EfS in WA secondary schools.

Marine and Freshwater Research 65, no. 6 (2014): 486. http://dx.doi.org/10.1071/mf13179.
Full textAbstract:
In the present study, we investigate the potential impact of the first proposed interstate translocation of mussel spat, for aquaculture enhancement, on the genetic integrity of Mytilus populations in Western Australia (WA). We performed genetic analysis on four populations (Garden Island, Bunbury, Albany and Esperance) in WA and on mussels from three hatcheries in South Australia (SA), Victoria (Vic) and Tasmania (Tas) proposed as spat sources in the translocation application. Two genetically distinct groups of M. galloprovincialis were identified, which corresponded to introduced Northern Hemisphere and native Southern Hemisphere haplotypes. Mussels obtained from the hatcheries showed a marked proportion of native haplotypes, while mussels of three (Garden Island, Bunbury and Esperance) of the four sampled WA Mytilus populations consisted mostly of introduced haplotypes. Most importantly, all samples were notable for a mixture of native and introduced haplotypes with the great majority of introduced haplotypes occurring in both WA and eastern states samples. Based on these results, it seems unlikely that the proposed translocation of mussel spat could negatively impact WA Mytilus populations. The current study presents valuable information regarding the genetic composition of Mytilus populations and will prove useful in the assessment of future translocation applications and biodiversity of mussel species in WA.

Full textAbstract:
IntroductionCoronary artery bypass grafting (CABG) and percutaneous coronary interventions (PCI) are procedures commonly performed on patients with significant obstructive coronary artery disease to relieve symptoms of ischaemia, improve survival or both. Although the efficacy of both procedures at the individual level has been established, the impact of advances in coronary artery revascularisation procedures (CARP) on long-term outcomes and cost-effectiveness at the population level are yet to be assessed. Our aim is to evaluate a minimum of 6-year outcomes and costs for the total population of patients who had CARP in Western Australia (WA) in 2000–2005.Methods and analysisThis retrospective population cohort study will link clinical and administrative health data for a previously defined cohort including all patients in WA who had a CARP in the period 2000–2005. The cohort consists of 19 014 patients who had 21 175 procedures (15 429 PCI and 5746 CABG). We are now collecting a minimum of 6 years follow-up of morbidity and mortality data for the cohort using the WA Data Linkage System, clinical registries and hospital records, with 12 years follow-up for cases in the year 2000. Comparison of long-term outcomes for different CARP will be reported (PCI vs CABG; bare metal stents vs drug-eluting stents vs CABG). Cost-effectiveness analysis of CARP from the perspective of the healthcare sector will be performed using individual level cost data and average costs from Australian Refined Diagnosis Related Groups.Ethics and disseminationThis study has received ethics approval from the University of Western Australia, the Western Australian Department of Health and all participating hospitals. Being a large population cohort study, approval included a waiver of informed consent. All findings will be presented at local, national and international healthcare/academic conferences and published in peer-reviewed journals.

Full textAbstract:
This extended abstract discusses the key challenges associated with the Coniston development; particular emphasis is on engineering, operations, and project management aspects. The Coniston development will produce oil and gas from the Coniston and Novara hydrocarbon accumulations, located in permit WA-35-L, about 100 km north of Exmouth, in water depths of about 400 m. The Coniston development will consist of a sub-sea tieback to the existing Van Gogh sub-sea infrastructure and the Ningaloo Vision FPSO, currently producing from the Van Gogh Field. The project was sanctioned by Apache in 2011 and will be on production in 2Q 2014. To maximise reservoir exposure, multilateral wells will be drilled, and completed, employing inflow control devices of latest generation and monitoring production with the installation of tracers. To take advantage of project synergies, gas lift will be provided by Van Gogh wells through a dedicated gas production manifold. The Coniston development represents a remarkable multidisciplinary effort to develop a relatively small-size oil reservoir offshore WA. Some of the challenges achieved are the high oil viscosity, the complexity of the engineering to install new sub-sea infrastructure while minimising the impact on Van Gogh production and maximising the synergies of the tie back, the constant increase in drilling and facilities costs while maintaining attractive project economics, and the more stringent regulations environmental permits and the ability to optimise drilling and operation to achieve production as quickly as possible.

Full textAbstract:
Two new species of hippolytid shrimp are described from the continental margin of Western Australia, Lebbeus clarehannah sp. nov. from one female specimen collected off Bald Island, WA, at depths of 408–431 m and Lebbeus cristagalli sp. nov. from ten specimens collected off north-western Australia at depths of 397–458 m. Both species belong to the group of Lebbeus species possessing epipods on only the first two pairs of pereopods. Within this group, they are similar to L. yaldwyni Kensley, Tranter & Griffin, 1987 from NSW, Australia, and L. compressus Holthuis, 1947 from Japan in possessing a high crest on the carapace. These crested species of Lebbeus are reviewed. They can be distinguished from one another by the shape of the carapace crest, the number of spines on maxilliped 3 and by colour pattern. A key to all crested species and colour photos of the Australian species are provided.

Full textAbstract:
Objective Antenatal testing for specified sexually transmissible infections (STIs) and blood-borne viruses (BBVs) is recommended by the Royal Australian and New Zealand College of Obstetricians and Gynaecologists (RANZCOG). In 2007, the Department of Health, Western Australia (DoHWA) issued an operational directive (OD) recommending universal testing for chlamydia and additional testing for women in the STI endemic regions of Western Australia (WA). To assess adherence to these guidelines, seven WA public hospitals were audited. Design and setting: Demographic details and testing information of the last 200 women who gave birth immediately before 30 June 2007 (baseline audit) and 30 June 2010 (follow-up audit) were obtained from each hospital’s antenatal records. Results: Data from 2718 women who delivered at ≥36 weeks’ gestation were analysed (baselinen = 1353; follow-upn = 1365). Testing at the first antenatal visit in accordance with the guidelines improved over time (RANZCOG: 68–74%; χ2-test = 13.96, d.f. = 1, P < 0.001; DoHWA OD: 12–40%; χ2-test = 279.71, d.f. = 1, P < 0.001). Retesting at 28–36 weeks’ gestation in the STI endemic regions improved for chlamydia (3–10%; χ2-test = 17.40, d.f. = 1, P < 0.001) and gonorrhoea (3–7%; χ2-test = 6.62, d.f. = 1, P < 0.05), but not for syphilis or HIV. Chlamydia prevalence was 3% and 8% among nonAboriginal and Aboriginal women, respectively. Conclusion: The proportion of women delivering in WA public hospitals who had antenatal STI and BBV tests improved after publication and promotion of the OD.
