Changes in exposure to 'life stressors' in the Aboriginal and Torres Strait Islander population, 2002 to 2008

The Negative Life Events Scale (NLES) has been included in nationally representative surveys of the Indigenous and Australian population since 2002 as a measure of exposure to a range of 'life stressors'. There has been limited reporting or analysis of estimates of the NLES from these surveys. This paper reports changes in exposure to stressors from 2002 to 2008 for the Indigenous population, and examines inter-relationships between eleven NLES items. Data for the 2006 Australian population is also included for comparative purposes.

Aboriginal and Torres Strait Islander People in the accounting profession : an exploratory study

The aim of this article is to explore the role that accounting skills and accounting qualifications may play in entering fields that have been virtually closed to Aboriginal and Torres Strait Islander (ATSI) people. It is acknowledged in the literature that accounting processes and accountants have historically had a domineering and detrimental impact on marginalised groups, such as ATSI peoples. However, we propose an alternative viewpoint using a Bourdieun perspective and theorise that accounting skills and accounting qualifications (capital) can open doors to powerful organisations and institutions (fields). As this is an exploratory study, we have limited our analysis to one key aspect of the Bourdieun framework, namely that of field. To that end, we examine accounting and other organisations that have traditionally closed their doors to marginalised groups in society. Interviews were conducted with ATSI people who have successfully gained entry into the field of the accounting profession, in an effort to understand the experiences and barriers they faced and to investigate the role that accounting skills plays in enabling ATSI people access to fields and decision-making positions that have traditionally been inaccessible to them.

Programs to improve the social and emotional wellbeing of Aboriginal and Torres Strait Islander communities

Attending to the social and emotional wellbeing of those from Aboriginal and Torres Strait Islander cultural backgrounds is widely recognised to play a key role in effective social work practice. However, relatively little is currently known about what effective practice comprises, and significant challenges exist in any effort to demonstrate that programs do achieve significant change both for individual participants and the communities in which they live. This paper considers one program, Seasons for Healing, to illustrate the type of intervention that holds promise when working with adults and discusses the difficulties that arise in both defining and assessing program outcomes.

Classification of coral reef types in Torres Strait (GIS files in zip-archive 319 kB)

Coral reefs represent major accumulations of calcium carbonate (CaCO3). The particularly labyrinthine network of reefs in Torres Strait, north of the Great Barrier Reef (GBR), has been examined in order to estimate their gross CaCO3 productivity. The approach involved a two-step procedure, first characterising and classifying the morphology of reefs based on a classification scheme widely employed on the GBR and then estimating gross CaCO3 productivity rates across the region using a regional census-based approach. This was undertaken by independently verifying published rates of coral reef community gross production for use in Torres Strait, based on site-specific ecological and morphological data. A total of 606 reef platforms were mapped and classified using classification trees. Despite the complexity of the maze of reefs in Torres Strait, there are broad morphological similarities with reefs in the GBR. The spatial distribution and dimensions of reef types across both regions are underpinned by similar geological processes, sea-level history in the Holocene and exposure to the same wind/wave energetic regime, resulting in comparable geomorphic zonation. However, the presence of strong tidal currents flowing through Torres Strait and the relatively shallow and narrow dimensions of the shelf exert a control on local morphology and spatial distribution of the reef platforms. A total amount of 8.7 million tonnes of CaCO3 per year, at an average rate of 3.7 kg CaCO3 m-2 yr-1 (G), were estimated for the studied area. Extrapolated production rates based on detailed and regional census-based approaches for geomorphic zones across Torres Strait were comparable to those reported elsewhere, particularly values for the GBR based on alkalinity-reduction methods. However, differences in mapping methodologies and the impact of reduced calcification due to global trends in coral reef ecological decline and changing oceanic physical conditions warrant further research. The novel method proposed in this study to characterise the geomorphology of reef types based on classification trees provides an objective and repeatable data-driven approach that combined with regional census-based approaches has the potential to be adapted and transferred to different coral reef regions, depicting a more accurate picture of interactions between reef ecology and geomorphology.

Snoring and its association with asthma in Indigenous children living in the Torres Strait and Northern Peninsula Area

Objective: Respiratory health of Indigenous and minority ethnic groups in affluent countries is poorer than their non-minority counterparts and sleep disorders are no exception. In children, obstructive sleep apnoea has the potential to result in serious long-term consequences. In 1999, we studied 1650 children and adolescents living in the Torres Strait and the Northern Peninsula Area, Australia. Here we report prevalence of snoring in these communities and relate its association with asthma symptoms. Methods: A population-based cross-sectional study was conducted in the Torres Strait region. Five indigenous communities were randomly selected and information was collected using a structured face-to-face interview based on a standardized questionnaire. There was a 98% response rate, and 1650 children, 0-17 years of age, were included in the study. Results: Overall, the prevalence of snoring was 14.2% (95% CI 12.5-15.9); 3.6% (95% CI 2.7-4.6) reported snorting, and 6% (95% CI 4.9-7.2) reported restless sleep. The prevalence of snoring was significantly higher among males (17.1% for males and 10.8 for females, P = 0.005). Children were five times more likely to have experienced snoring and snorting if they reported wheezing in the last 12 months. Conclusion: We conclude that the prevalence of symptoms suggestive of obstructive sleep problems is relatively high in children of this region. This highlights the need for awareness among the community patients and physicians about the problem of obstructive sleep-disordered breathing, especially in children with asthma, and for the need for further studies to measure prevalence of sleep breathing disorders among Indigenous Australians.

Flavivirus isolations from mosquitoes collected from Saibai Island in the Torres Strait, Australia, during an incursion of Japanese encephalitis virus

Adult mosquitoes (Diptera: Culicidae) were collected in January and February 2000 from Saibai Island in the Torres Strait of northern Australia, and processed for arbovirus isolation during a period of Japanese encephalitis (JE) virus activity on nearby Badu Island. A total of 84 2 10 mosquitoes were processed for virus isolation, yielding six flavivirus isolates. Viruses obtained were single isolates of JE and Kokobera (KOK) and four of Kunjin (KUN). All virus isolates were from members of the Culex sitiens Weidemann subgroup, which comprised 53.1 % of mosquitoes processed. Nucleotide sequencing and phylogenetic analysis of the pre-membrane region of the genome of JE isolate TS5313 indicated that it was closely related to other isolates from a sentinel pig and a pool of Cx. gelidus Theobald from Badu Island during the same period. Also molecular analyses of part of the envelope gene of KUN virus isolates showed that they were closely related to other KUN virus strains from Cape York Peninsula. The results indicate that flaviviruses are dynamic in the area, and suggest patterns of movement south from New Guinea and north from the Australian mainland.

Kurturawniaiwak (Badu) and the archaeology of villages in Torres Strait.

Despite more than 30 years of archaeological research, not a single detailed site report has ever been published for a village site in Torres Strait. This paper presents the results of small-scale excavations at the 700 year old village of Kurturniaiwak on Badu island in mid-western Torres Strait. It represents the first in an ongoing series of systematic excavations of village sites in this part of Torres Strait. Initial results support conclusions of major socio-cultural change for the region as recently proposed by McNiven, and indicate that a major reconfiguration of settlement-subsistence-ritual systems probably took place in western Torres Strait sometime between 600 and 800 years ago.
