Instilling postcolonial nostalgias : Ned Kelly narratives for children

This essay examines books for children focusing on Ned Kelly and the Kelly gang, published from 2000 to 2011. Drawing upon theories of narrative, memory and nostalgia it analyses the narrative strategies and visual images through which these texts position readers, and their investment in formulations of the Australian nation. The essay argues that these books function as exercises in restorative nostalgia, producing palatable versions of Kelly as an Australian hero, and articulating connections between the Kelly legend and Australian national identity. By foregrounding Kelly's Irishness and by representing him as a “good badman”, these Ned Kelly narratives for children, which range across fiction, non-fiction, picture book and play script, reinscribe versions of national identity which occlude more complicated narratives. In particular, their emphasis on struggles between Irish and English settlers, and between selectors and squatters, displaces Indigenous histories, colonial violence, and systemic discrimination against those deemed outsiders to the nation.

The health-related quality of life burden of co-morbid cardiovascular disease and major depressive disorder in Australia : findings from a population-based, cross-sectional study

Purpose Health-related quality of life (HRQOL) can be significantly impaired by the presence of chronic conditions such as cardiovascular disease (CVD) and major depressive disorder (MDD). The aim of this paper was to (1) identify differences in HRQOL between individuals with CVD, MDD, or both, compared to a healthy reference group, (2) establish whether the influence of co-morbid MDD and CVD on HRQOL is additive or synergistic and (3) determine the way in which depression severity interacts with CVD to influence overall HRQOL.

Methods Population-based data from the 2007 Australian National Survey of Mental Health and Well-being (NSMHWB) (n = 8841) were used to compare HRQOL of individuals with MDD and CVD, MDD but not CVD, CVD but not MDD, with a healthy reference group. HRQOL was measured using the Assessment of Quality of Life (AQOL). MDD was identified using the Composite International Diagnostic Interview (CIDI 3.0).

Results Of all four groups, individuals with co-morbid CVD and depression reported the greatest deficits in AQOL utility scores (Coef: −0.32, 95% CI: −0.40, −0.23), after adjusting for covariates. Those with MDD only (Coef: −0.27, 95% CI: −0.30, −0.24) and CVD only (Coef: −0.08, 95% CI: −0.11, −0.05) also reported reduced AQOL utility scores. Second, the influence of MDD and CVD on HRQOL was shown to be additive, rather than synergistic. Third, a significant dose–response relationship was observed between depression severity and HRQOL. However, CVD and depression severity appeared to act independently of each other in impacting HRQOL.

Conclusions HRQOL is greatly impaired in individuals with co-morbid MDD and CVD; these conditions appear to influence HRQOL in an additive fashion. HRQOL alters with depression severity, therefore treating depression and improving HRQOL is of clinical importance.

Fuzzy ARTMAP and a hybrid chaos genetic algorithm for medical pattern classification

In this paper, an Evolutionary Artificial Neural Network (EANN), which combines the Fuzzy ARTMAP (FAM) neural network and a hybrid Chaos Genetic Algorithm (CGA), is proposed for undertaking pattern classification tasks. The hybrid CGA is a modified version of the hybrid real-coded genetic algorithms that includes a Chaotic Mapping Operator (CMO) in its search and adaptation process. It is used to evolve the connection weights in FAM, and the resulting EANN is known as FAM-hybrid CGA. The CMO in the hybrid CGA is used to generate a group of chromosomes that incorporates the characteristics of chaos. The chromosomes are then adapted with an arbitrary small amount of variation in every generation. As the evolution procedure proceeds, chromosomes with considerable differences are produced. Such chromosomes, which are located at different regions of interest in the solution space, are able to provide good solutions to undertake search and adaption problems. The effectiveness of the proposed FAM-hybrid CGA model is first evaluated using benchmark medical data sets from the UCI machine learning repository. Its applicability to medical decision support is then demonstrated using a real database of patient records with suspected Acute Coronary Syndrome. The results indicate that FAM-hybrid CGA is able to outperform its neural network counterpart (i.e., FAM), and it can be employed as a useful pattern classification tool for tackling medical decision support tasks.

Visual networking : Australia's media landscape

Australia is in the midst of a massive transformation of its communication infrastructure. The AUD43 billion Australian National Broadband Network (NBN) to be set up by the wholly Federal government-owned NBNCo Limited (NBNCo), is the largest infrastructure project ever proposed in Australia (NBN, 2010). It has the capacity to combine features and technologies that were once separate, but now have converged, including computing, telephony, free-to-air (FTA) television, direct-to-home satellite broadcasting, radio and the internet. This means that current thinking about these media technologies, developed through the process of convergence as well as regulation, requires review. Future services for digital television are going to be more akin to app-based functions currently available on mobiles and tablets but accessed via the television screen rather than the PC. Against such a background, this article examines the Australian ‘televisual’ space, arguing that faster broadband and internet-enabled televisions for movies, shows, communication and more, when it suits the audience, are the keys to television’s survival through visually networked possibilities.

Unsung oz hysteries

The screening and funding opportunities for Experimental film in Australia has always had a problematic and underground history since the 1960s, moving through 16mm, super 8 and now digital moving image forms. One source of that history was Cantrills Filmnotes which expressed the rhetoric of a founding generation who experience the promise of a new Australian National Cinema and new film culture in the 70s, but whose mainstream product eventually left it behind. Experimental film inherited a marginal position through a lack of critical debate and because funding shifts left its identity somewhere between the fine arts and commercial cinema. It was consequently viewed as marginal to both. The general visual quality of this work meant it was perceived as apolitical, although it implicitly expressed and performed the denials and negations experienced directly by the migrant and working classes.

Through several cycles of emerging generations of artists (through such organizations as Fringe Network, MIMA and Experimenta), such artists knew more of the histories of work emanating from Europe and North America than their own, a general problem for Australian history. New underground opportunities are now arising to connect with the emerging and aspirant cultures coming out of Asia that reflect the shifts of global capital and the rise of China as an economic power. Asian work, registering a history of aspiration offers a re-integration of Peter Wollen’s avant-gardes split from the early 70s in the West. In the academy the Avant-garde’s strategies and techniques are studied, but are offered up in new work as aesthetic and lifestyle choices, rather than as the political imperatives announced implicitly or explicitly in their originating forms.

Attendance at cardiac rehabilitation is associated with lower all-cause mortality after 14 years of follow-up

Objective To investigate whether attendance at cardiac rehabilitation (CR) independently predicts all-cause mortality over 14 years and whether there is a dose–response relationship between the proportion of CR sessions attended and long-term mortality.

Design Retrospective cohort study.

Setting CR programmes in Victoria, Australia

Patients The sample comprised 544 men and women eligible for CR following myocardial infarction, coronary artery bypass surgery or percutaneous interventions. Participants were tracked 4 months after hospital discharge to ascertain CR attendance status.

Main outcome measures All-cause mortality at 14 years ascertained through linkage to the Australian National Death Index.

Results In total, 281 (52%) men and women attended at least one CR session. There were few significant differences between non-attenders and attenders. After adjustment for age, sex, diagnosis, employment, diabetes and family history, the mortality risk for non-attenders was 58% greater than for attenders (HR=1.58, 95% CI 1.16 to 2.15). Participants who attended <25% of sessions had a mortality risk more than twice that of participants attending ≥75% of sessions (OR=2.57, 95% CI 1.04 to 6.38). This association was attenuated after adjusting for current smoking (OR=2.06, 95% CI 0.80 to 5.29).

Conclusions This study provides further evidence for the long-term benefits of CR in a contemporary, heterogeneous population. While a dose–response relationship may exist between the number of sessions attended and long-term mortality, this relationship does not occur independently of smoking differences. CR practitioners should encourage smokers to attend CR and provide support for smoking cessation.

Prevalence and community variation in harmful levels of family conflict witnessed by children: implications for prevention

 Abstract
Children’s reports of high family conflict consistently predict poor outcomes. The study identified criteria for high family conflict based on prospective prediction of increased risk for childhood depression. These criteria were subsequently used to establish the prevalence of high family conflict in Australian communities and to identify community correlates suitable for targeting prevention programs. Study 1 utilised a longitudinal design. Grade 6 and 8 students completed a family conflict scale (from the widely used Communities That Care survey) in 2003 and depression symptomotology were evaluated at a 1-year follow-up (International Youth Development Study, N = 1,798). Receiver-operating characteristic analysis yielded a cut-off point on a family conflict score with depression symptomatology as a criterion variable. A cut-off score of 2.5 or more (on a scale of 1 to 4) correctly identified 69 % with depression symptomology, with a specificity of 77.2 % and sensitivity at 44.3 %. Study 2 used data from an Australian national survey of Grade 6 and 8 children (Healthy Neighbourhoods Study, N = 8,256). Prevalence estimates were calculated, and multivariate logistic regression with multi-level modelling was used to establish factors associated with community variation in family conflict levels. Thirty-three percent of Australian children in 2006 were exposed to levels of family conflict that are likely to increase their future risk for depression. Significant community correlates for elevated family conflict included Indigenous Australian identification, socioeconomic disadvantage, urban and state location, maternal absence and paternal unemployment. The analysis provides indicators for targeting family-level mental health promotion programs.

Material world: learning and teaching chemistry

 In the Australian National Curriculum, the science understanding of overarching ideas of matter and energy covers science topics in the conceptual area of chemistry, such as the properties, forms and uses of different materials, the states of matter (solid, liquid and gas), and energy, such as forces, movement and electricity. This chapter focusses on explaining the abstract science ideas related to matter and energy through the use of appropriate vocabulary, examining ways of organising knowledge and linking scientific models and theories to observations and experiences. The particle model of matter is used to explain common observations, demonstrating the value of scientific inquiry and the role of models and representations in scientific thinking. A directed inquiry teaching approach in which there is a focus on the use of representations is recommended for these abstract topics. Representations are a vital component of communicating the abstract ideas of matter and energy. The use of the pedagogical approach in which students construct and evaluate representations of scientific ideas is used in the negotiation and development of their understandings.

Type 2 diabetes prevalence varies by socio-economic status within and between migrant groups: analysis and implications for Australia

Background:
Ethnic diversity is increasing through migration in many developed countries. Evidence indicates that type 2 diabetes mellitus (T2DM) prevalence varies by ethnicity and socio- economic status (SES), and that in many settings, migrants experience a disproportionate burden of disease compared with locally-born groups. Given Australia’s multicultural demography, we sought to identify groups at high risk of T2DM in Victoria, Australia.

An assessment of empowerment through highly participatory asset-based community development in Myanmar

Asset-based community development (ABCD) is a highly participatory approach to development that seeks to empower communities to draw on tangible and social community assets to manage their own development. The strength of ABCD is its ability to facilitate people imagining their world differently, resulting in action to change their circumstances. Previous research has shown international non-government organisations have found highly participatory, community-led approaches to development to have been particularly effective forms of poverty mitigation and community empowerment within Myanmar, even before the current reforms, which is surprising given the restrictive socio-political context created by authoritarian rule by a regime with an international reputation for human rights violations. 

This paper documents ABCD programs within Myanmar, one of the poorest countries in Asia suffering major underdevelopment and ranking poorly across a wide range of socioeconomic indicators. It explores the operation, effectiveness and reasons behind the success of ABCD programs in this environment, and reflects on the role of outsiders in ABCD in the light of underlying theory and this contemporary experience. This research draws largely on recent field interviews and personal experience working in this sector within Myanmar, as well as surveying a number of evaluation reports which have been made publically available.
