Deeply divergent mitochondrial lineages reveal patterns of local endemism in chironomids of the Australian Wet Tropics

The Wet Tropics bioregion of north-eastern Australia has been subject to extensive fluctuations in climate throughout the late Pliocene and Pleistocene. Cycles of rainforest contraction and expansion of dry sclerophyll forest associated with such climatic fluctuations are postulated to have played a major role in driving geographical endemism in terrestrial rainforest taxa. Consequences for the distributions of aquatic organisms, however, are poorly understood.The Australian non-biting midge species Echinocladius martini Cranston (Diptera: Chironomidae), although restricted to cool, well-forested freshwater streams, has been considered to be able to disperse among populations located in isolated rainforest pockets during periods of sclerophyllous forest expansion, potentially limiting the effect of climatic fluctuations on patterns of endemism. In this study, mitochondrial COI and 16S data were analysed for E. martini collected from eight sites spanning theWet Tropics bioregion to assess the scale and extent of phylogeographic structure. Analyses of genetic structure showed several highly divergent cryptic lineages with restricted geographical distributions. Within one of the identified lineages, strong genetic structure implied that dispersal among proximate (<1 km apart) streams was extremely restricted. The results suggest that vicariant processes, most likely due to the systemic drying of the Australian continent during the Plio-Pleistocene, might have fragmented historical E. martini populations and, hence, promoted divergence in allopatry.

The relative age effect in Australian Football League players

Youth sports teams are usually grouped into yearly age groups based on fixed cut-off date (September 1st in the UK and January 1st in Australia). Children born just after this cut-off will be the oldest and most mature in their age group. This gives them an advantage in competitive sport, an advantage which has persisted into adulthood as shown by seasonal patterns in the dates of birth of professional ice hockey, football and basketball players. We were interested in whether a similar seasonal pattern exists in professional Australian Football League (AFL) players. We examined all AFL players in the 2009 season excluding foreign-born players. We compared the observed number of players’ born in each month with the expected number based on national statistics. There was a marked and statistically significant seasonality in players’ dates of birth. There were 33% more players than expected with dates of birth in January, and 25% fewer in December. Players who are relatively older in youth AFL teams have a better chance of turning professional.

More than experiential learning or volunteering : a case study of community service learning within the Australian context

Community service learning is the integration of experiential learning and community service into coursework such that community needs are met and students gain both professional skills and a sense of civic responsibility. A critical component is student reflection. This paper provides an example of the application of community service learning within an undergraduate health unit at the Queensland University of Technology. Based on survey data from 36 program participants, it demonstrates the impact of CSL on student outcomes. Results show that students benefited by developing autonomy through real world experiences, through increased self-assurance and achievement of personal growth, through gaining new insights into the operations of community service organisations and through moving towards becoming responsible citizens. Students expect their CSL experience to have long-lasting impact on their lives, with two-thirds of participants noting that they would like to continue volunteering as part of their future development.

Learning to be literate : issues of pedagogy for recently arrived refugee youth in Australia

This paper focuses on issues of access to productive literacy learning as part of socially just schooling for recently arrived refugee youth within Australia. It argues that a sole reliance on traditional ESL pedagogy is failing this vulnerable group of students, who differ significantly from past refugees who have settled in Australia. Many have been ‘placeless’ for some time, are likely to have received at best an interrupted education before arriving in Australia, and may have experienced signification trauma (Christie & Sidhu, 2006; Cottone, 2004; Miller, Mitchell, & Brown, 2005). Australian Government policy has resulted in spacialized settlement, leaving particular schools dealing with a large influx of refugee students who may be attending school for the first time (Centre for Multicultural Youth Issues, 2004; Sidhu & Christie, 2002). While this has implications generally, it has particular consequences for secondary school students attempting to learn English literacy in short periods of time, without basic foundations in either English or print-based literacy in any first language (Centre for Multicultural Youth Issues, 2006). Many of these students leave schools without the most basic early literacy practices, having endured several years of pedagogy pitched well beyond their needs. This paper suggests that schools must take up three key roles: to educate, to provide a site for the development of civic responsibility, and to act as a site for welfare with responsibility. As a system, our department needs to work out what can we do for 17-18 year olds that are coming into our school system in year 10 without more than 1-2 years of education. I don't think there is a policy about what to do. – (T2-ESL teacher)

Australian horror movies

The Australian horror film is a fascinating specimen. While a tradition has antecedents in the silent era of cinema, and at times has produced popular and commercially successful titles, Australian horror films have existed among the shadows of Australian cinema. Within a national cinema funded by public subsidy to foster a sense of national identity, emphasizing ‘quality’ cultural films and refusing to recognize popular movie genres in attempt to differentiate itself from Hollywood, generic and low-culture horror films have been in opposition to these objectives. Consequently, horror movies have been heavily marginalized within public funding environments and mainstream film culture, and either ignored or despised by mainstream critics. The chapter provides a historical introduction to Australian horror cinema before reviewing a selection of recent Aussie horror titles, namely: Wolf Creek, Undead, Black Water, Dying Breed, Lost Things, Prey, Cut, Rogue and Storm Warning.

A comparison of international occupational therapy competencies : implications for Australian standards in the new millennium

Background/aim: A timely evaluation of the Australian Competency Standards for Entry-Level Occupational Therapists© (1994) was conducted. This thorough investigation comprised a literature review exploring the concept of competence and the applications of competency standards; systematic benchmarking of the Australian Occupational Therapy Competency Standards (OT AUSTRALIA, 1994) against other national and international competency standards and other affiliated documents, from occupational therapy and other cognate disciplines; and extensive nationwide consultation with the professional community. This paper explores and examines the similarities and disparities between occupational therapy competency standards documents available in English from Australia and other countries.----- Methods: An online search for national occupational therapy competency standards located 10 documents, including the Australian competencies.----- Results: Four 'frameworks' were created to categorise the documents according to their conceptual underpinnings: Technical-Prescriptive, Enabling, Educational and Meta-Cognitive. Other characteristics that appeared to impact the design, content and implementation of competency standards, including definitions of key concepts, authorship, national and cultural priorities, scope of services, intended use and review mechanisms, were revealed.----- Conclusion: The proposed 'frameworks' and identification of influential characteristics provided a 'lens' through which to understand and evaluate competency standards. While consistent application of and attention to some of these characteristics appear to consolidate and affirm the authority of competency standards, it is suggested that the national context should be a critical determinant of the design and content of the final document. The Australian Occupational Therapy Competency Standards (OT AUSTRALIA, 1994) are critiqued accordingly, and preliminary recommendations for revision are proposed.

Measurement properties of the Australian Women's Activity Survey

Purpose: The Australian Women’s Activity Survey (AWAS) was developed based on a systematic review and qualitative research on how to measure activity patterns of women with young children (WYC). AWAS assesses activity performed across five domains (planned activities, employment, childcare, domestic responsibilities and transport), and intensity levels (sitting, light-intensity, brisk walking, moderate-intensity and vigorous-intensity) in a typical week in the past month. The purpose of this study was to assess the test-retest reliability and criterion validity of the AWAS. Methods: WYC completed the AWAS on two occasions 7-d apart (test-retest reliability protocol) and/or wore an MTI ActiGraph accelerometer for 7-d in between (validity protocol). Forty WYC (mean age 35 ± 5yrs) completed the test-retest reliability protocol and 75 WYC (mean age 33 ± 5yrs) completed the validity protocol. Interclass Correlation Coefficients (ICC) between AWAS administrations and Spearman’s Correlation Coefficients (rs) between AWAS and MTI data were calculated. Results: AWAS showed good test-retest reliability (ICC=0.80 (0.65-0.89)) and acceptable criterion validity (rs= 0.28, p=0.01) for measuring weekly health-enhancing physical activity. AWAS also provided repeatable and valid estimates of sitting time (test-retest reliability ICC=0.42 (0.13-0.64), and criterion validity (rs= 0.32, p=0.006)). Conclusion: The measurement properties of the AWAS are comparable to those reported for existing self-report measures of physical activity. However, AWAS offers a more comprehensive and flexible alternative for accurately assessing different domains and intensities of activity relevant to WYC. Future research should investigate whether the AWAS is a suitable measure of intervention efficacy by examining its sensitivity to change.

Airports in their urban settings : towards a conceptual model of interfaces in the Australian context

In Australia, airports have emerged as important sub-regional activity centres and now pose challenges for both airport operation and planning in the surrounding urban and regional environment. The changing nature of airports in their metropolitan context and the emergence of new pressures and problems require the introduction of a fresh conceptual framework to assist the better understanding of these complex roles and spatial interactions. The approach draws upon the meta-concept of interfaces of an ‘airport metropolis’ as an organising device consisting of four main domains: economic development, land use,infrastructure, and governance. The paper uses the framework to further discuss airport and regional interactions and highlights the use of sustainability criteria to operationalise the model. The approach aims to move research and practice beyond the traditionally compartmentalised analysis of airport issues and policy-making by highlighting interdependencies between airports and regions.

Show me a bad kid and I’ll show you a lousy parent : making parents responsible for youth crime in Australian and Canadian Contexts

This article surveys literature bearing on the issue of parental liability and responsibility for the crimes of young offenders, with a particular focus on comparing different approaches to dealing with the issue in Australia and Canada. This comparative analysis of Australian and Canadian legislative and policy approaches is situated within a broader discussion of arguments about the “punitive turn” in youth justice, responsibilisation, and cross-jurisdictional criminal justice policy transfer and convergence. Our findings suggest that there are significant differences in the manner and extent to which Australia and Canada have invoked parental responsibility laws and policies as part of the solution to dealing with youth crime. We conclude by speculating on some of the reasons for these differences and establishing an agenda for additional needed cross-jurisdictional research. In particular, we argue that it would be fruitful to undertake a cross-jurisdictional study that examines the development and effects of parental responsibility laws across a larger number of different Western countries as well as across individual states and provinces within these national jurisdictions.

Malnutrition and pressure ulcer risk in adults in Australian health care facilities

Aims To determine the effect of nutritional status on the presence and severity of pressure ulcers in statewide? public healthcare facilities, in Queensland, Australia. Research Methods A multicentre, cross sectional audit of nutritional status of a convenience sample of subjects was carried out as part of a large audit of pressure ulcers in a sample of state based public healthcare facilities in 2002 and 2003. Dietitians in 20 hospitals and six residential aged care facilities conducted single day nutritional status audits of 2208 acute and 839 aged care subjects using the Subjective Global Assessment. The effect of nutritional status on the presence, highest stage and number of pressure ulcers was determined by logistic regression in a model controlling for age, gender, medical specialty and facility location. The potential clustering effect of facility was accounted for in the model using an analysis of correlated data approach. Results Subjects with malnutrition had an adjusted odds risk of 2.6 (95% CI 1.8-3.5, p<0.001) of having a pressure ulcer in acute facilities and 2.0 (95% CI 1.5-2.7, p<0.001) for residential aged care facilities. There was also increased odds risk of having a pressure ulcer, having a higher stage pressure ulcer and a higher number of pressure ulcers with increased severity of malnutrition. Conclusion Malnutrition was associated with at least twice the odds risk of having a pressure ulcer of in public healthcare facilities in Queensland. Action must be taken to identify, prevent and treat malnutrition, especially in patients at risk of pressure ulcer.

Confidence to cook vegetables and the buying habits of Australian households

Cooking skills are emphasized in nutrition promotion but their distribution among population subgroups and relationship to dietary behavior is researched by few population-based studies. This study examined the relationships between confidence to cook, sociodemographic characteristics, and household vegetable purchasing. This cross-sectional study of 426 randomly selected households in Brisbane, Australia, used a validated questionnaire to assess household vegetable purchasing habits and the confidence to cook of the person who most often prepares food for these households. The mutually adjusted odds ratios (ORs) of lacking confidence to cook were assessed across a range of demographic subgroups using multiple logistic regression models. Similarly, mutually adjusted mean vegetable purchasing scores were calculated using multiple linear regression for different population groups and for respondents with varying confidence levels. Lacking confidence to cook using a variety of techniques was more common among respondents with less education (OR 3.30; 95% confidence interval [CI] 1.01 to 10.75) and was less common among respondents who lived with minors (OR 0.22; 95% CI 0.09 to 0.53) and other adults (OR 0.43; 95% CI 0.24 to 0.78). Lack of confidence to prepare vegetables was associated with being male (OR 2.25; 95% CI 1.24 to 4.08), low education (OR 6.60; 95% CI 2.08 to 20.91), lower household income (OR 2.98; 95% CI 1.02 to 8.72) and living with other adults (OR 0.53; 95% CI 0.29 to 0.98). Households bought a greater variety of vegetables on a regular basis when the main chef was confident to prepare them (difference: 18.60; 95% CI 14.66 to 22.54), older (difference: 8.69; 95% CI 4.92 to 12.47), lived with at least one other adult (difference: 5.47; 95% CI 2.82 to 8.12) or at least one minor (difference: 2.86; 95% CI 0.17 to 5.55). Cooking skills may contribute to socioeconomic dietary differences, and may be a useful strategy for promoting fruit and vegetable consumption, particularly among socioeconomically disadvantaged groups.
