Tuning the migrant voices : a study of Sinhala language ethnic radio programs in Melbourne

Ethnic radio was initiated in Australia to fulfill the issues of migrants through their language. This research, using the Sinhala language listeners in Melbourne as the target group analysed how the ethnic radio programs helped to achieve these goals.

Solving DC programs using the cutting angle method

In this paper, we propose a new algorithm for global minimization of functions represented as a difference of two convex functions. The proposed method is a derivative free method and it is designed by adapting the extended cutting angle method. We present preliminary results of numerical experiments using test problems with difference of convex objective functions and box-constraints. We also compare the proposed algorithm with a classical one that uses prismatical subdivisions. © 2014 Springer Science+Business Media New York.

Development by design in Western Australia : Overcoming offset obstacles

Biodiversity offsets can be an important tool for maintaining or enhancingenvironmental values in situations where development is sought despite negativeenvironmental impacts. There are now approximately 45 compensatory mitigationprograms for biodiversity impacts worldwide, with another 27 programs in development. While offsets have great potential as a conservation tool, their establishment requires overcoming a number of conceptual and methodological hurdles. In Australia, new policy changes at the national and state (i.e., Western Australia) level require that offsets follow a set of general principles: (1) Environmental offsets may not be appropriate for all projects and will only be considered after avoidance and mitigation options have been pursued;(2) Environmental offsets will be based on sound environmental information andknowledge; (3) Establishing goals for offsets requires an estimate of expected direct and indirect impacts; (4) Environmental offsets will be focused on longer term strategic outcomes; (5) Environmental offsets will be cost-effective, as well as relevant and proportionate to the significance of the environmental value being impacted. Here we focus on the challenges of determining and implementing offsets using a real world example from a voluntary offset process undertaken for Barrick Gold’s Kanowna Belle mine site in Western Australia to highlight those challenges and potential solutions.

Determinants and economic consequences of voluntary disclosure of internal control weaknesses in China

This paper investigates the determinants and economic consequences of disclosure of internal control weaknesses (ICWs) by Chinese listed firms under the voluntary disclosure regime over 2010-2011. We find that the probability of firms disclosing ICWs is not only associated with firm characteristics such as profitability, age and business complexity, but is also strongly related to the unique attributes of corporate governance and ownership structure in Chinese listed firms, e.g. the independence of the supervisory board, political connections, concentration of the top 3 shareholders' ownership and tradability of shares.Our results show that the severity of the ICWs disclosed is negatively and significantly associated with earnings response coefficients (ERCs), and audit assurance of ICRs has a significant moderating effect on the relationship between ICWs and ERCs. Our research adds further evidence to support the implementation of SOX-type regulations globally.

Supporting healthy communities through arts programs

There are some evaluations, critical descriptions of programs and systematic reviews on the benefits to Aboriginal and Torres Strait Islander communities from participation in arts programs. These include: improved physical and mental health and wellbeing; increased social inclusion and cohesion; some improvements in school retention and attitudes towards learning; increased validation of, and connection to, culture; improved social and cognitive skills; and some evidence of crime reduction.The effects of arts programs can be powerful and transformative. However, these effects tend to be indirect.For example, using these programs to reduce juvenile anti-social behaviour largely work through diversion: providing alternative safe opportunities to risk taking, maintenance of social status, as well as opportunities to build healthy relationships with Elders and links with culture.Art forms such as song, dance and painting, coupled with ceremony, are integral to cultural continuity and cultural maintenance in Indigenous Australian communities.

Mentoring programs for indigenous youth at-risk

There is a range of risk factors that may make young people of any ethnicity more likely to engage in antisocial behaviours. These factors include the young person’s own attitudes; relationships within the family; and growing up in communities where there is widespread violence, alcohol and other substance abuse, poverty, poor health and poor-quality housing. Indigenous young people face the additional challenges ofdispossession, discontinuity of culture and intergenerational trauma.A strong connection to culture—coupled with high self-esteem, a strong sense of autonomy, and with living in cohesive, functioning families and communities—can be protective factors that result in Indigenous young people choosing productive life pathways.Mentoring is a relationship intervention strategy that can assist in building some of these protective factors. A growing body of research demonstrates that mentoring can have powerful and lasting positive effects in improving behavioural, academic and vocational outcomes for at-risk youth and, to a more limited extent, in reducing contact with juvenile justice systems.In an Indigenous context, mentoring is a particularly promising initiative because it fits well with Indigenous teaching and learning styles and can help to build strong collective ties within a community.Mentoring programs can involve adult or peer mentors and can be implemented in a range of ways, such as one-on-one or in groups.Although positive results can be achieved with single-intervention mentoring for at risk youth, integrating mentoring into broader programs produces a greater level of positive change.The way the mentoring program is run and the nature of the relationship between mentor and mentee are crucial in determining the outcomes of youth mentoring programs.

Supporting healthy communities through sports and recreation programs

There is some evidence, in the form of critical descriptions of programs and systematic reviews, on the benefits to Aboriginal and Torres Strait Islander communities from participation in sport and recreational programs. These include some improvements in school retention, attitudes towards learning, social and cognitive skills, physical and mental health and wellbeing; increased social inclusion and cohesion; increased validation of and connection to culture; and crime reduction.Although the effects of sports and recreation programs can be powerful and transformative, these effects tend to be indirect. For example, using these programs to reduce juvenile antisocial behaviour largely work through diversion, providing alternative safe opportunities to risk taking, maintenance of social status, as wellas opportunities to build healthy relationships with Elders and links with culture.Although Indigenous Australians have lower rates of participation in sport than non-Indigenous people, surveys suggest that around one-third of Indigenous people participate in some sporting activity (ABS 2010). That makes sports a potentially powerful vehicle for encouraging Indigenous communities to look at challenging personal and community issues.Within Indigenous communities, a strong component of sport and recreation is the link with traditional culture. Cultural activities such as hunting are generally more accepted as a form of sport and recreation than traditional dance. Therefore sport and recreation are integral in understanding ‘culture’ within Indigenous communities, as well as highlighting the culture within which sport and recreation operate.

Maternal overnutrition programs changes in the expression of skeletal muscle genes that are associated with insulin resistance and defects of oxidative phosphorylation in adult male rat offspring.

Children of obese mothers have increased risk of metabolic syndrome as adults. Here we report the effects of a high-fat diet in the absence of maternal obesity at conception on skeletal muscle metabolic and transcriptional profiles of adult male offspring. Female Sprague Dawley rats were fed a diet rich in saturated fat and sucrose [high-fat diet (HFD): 23.5% total fat, 9.83% saturated fat, 20% sucrose wt:wt] or a normal control diet [(CD) 7% total fat, 0.5% saturated fat, 10% sucrose wt:wt] for the 3 wk prior to mating and throughout pregnancy and lactation. Maternal weights were not different at conception; however, HFD-fed dams were 22% heavier than controls during pregnancy. On a normal diet, the male offspring of HFD-fed dams were not heavier than controls but demonstrated features of insulin resistance, including elevated plasma insulin concentration [40.1 ± 2.5 (CD) vs 56.2 ± 6.1 (HFD) mU/L; P = 0.023]. Next-generation mRNA sequencing was used to identify differentially expressed genes in the offspring soleus muscle, and gene set enrichment analysis (GSEA) was used to detect coordinated changes that are characteristic of a biological function. GSEA identified 15 upregulated pathways, including cytokine signaling (P < 0.005), starch and sucrose metabolism (P < 0.017), inflammatory response (P < 0.024), and cytokine-cytokine receptor interaction (P < 0.037). A further 8 pathways were downregulated, including oxidative phosphorylation (P < 0.004), mitochondrial matrix (P < 0.006), and electron transport/uncoupling (P < 0.022). Phosphorylation of the insulin signaling protein kinase B was reduced [2.86 ± 0.63 (CD) vs 1.02 ± 0.27 (HFD); P = 0.027] and mitochondrial complexes I, II, and V protein were downregulated by 50-68% (P < 0.005). On a normal diet, the male offspring of HFD-fed dams did not become obese adults but developed insulin resistance, with transcriptional evidence of muscle cytokine activation, inflammation, and mitochondrial dysfunction. These data indicate that maternal overnutrition, even in the absence of prepregnancy obesity, can promote metabolic dysregulation and predispose offspring to type 2 diabetes.

Cost-effectiveness of whole-of-community obesity prevention programs: an overview of the evidence

Whole-of-community obesity prevention programs that impact on multiple players and promote community capacity show promise as an important strategy in the fight against global obesity. This paper reviews the economic evaluation literature of multifaceted, community based obesity prevention programs. There are few cost effectiveness studies. Whilst results to date are encouraging, there is considerable uncertainty surrounding the long term results given the lack of evidence regarding sustainability of program effect and a consequent reliance on economic modeling to fill the gaps. More empirical studies of longer duration are needed to demonstrate the longer term effectiveness and cost effectiveness of these programs, and to facilitate identification of the elements necessary for their sustainability.

Recidivism among participants of an employment assistance program for prisoners and offenders

Recidivism outcomes were examined over a 2-year postrelease period for participants of an Australian employment assistance program. The voluntary 12-month program operated from 17 Victorian correctional locations, 7 prisons, and 10 community corrections locations, targeting participants at moderate to high risk of reoffending. Recidivism outcomes included simple rates of reoffending for the whole program (N = 3,034 registered participants) and analyses of rate and seriousness of reoffending and extent of poly-offending for a random sample of 600 program participants and 600 nonparticipants. Offending among program participants' pre- and post-registration was also investigated. Results showed a very low rate of reoffending (7.46%) for the entire program participant group while engaged in the program. As well, program participants had significantly lower levels of recidivism than nonparticipants, and postregistration offending was significantly lower than preregistration offending. Findings indicate that long-term postrelease employment support programs provide positive benefits in terms of reduced reoffending.

Longitudinal evaluation of ICT intervention programs for girls

Intervention programs creating awareness among girls about the wide range of career opportunities in the Information and Communications Technology (ICT) field are conducted in many countries to tackle the problem of female under-representation in ICT. The long-term effects of these programs, however, are rarely evaluated which hinders the understanding of how they could be improved, their value and success factors. The goal of this study is, therefore, to investigate the longitudinal influence of one such program held biennially in Australia since 2006, by analysing survey data both quantitatively and qualitatively (n = 153). The results show that continuous study of an ICT subject at school by girls positively influences both their intention to choose a career in ICT and the actual choice of ICT as a university major. Moreover, the attitude towards the intervention program has a weak, but significant positive effect on the decision to study ICT at school.

The impact of IT intervention programs for girls

The goal of our study is to investigate the longitudinal effects of one intervention program for schoolgirls in the Information Technology (IT) field. This bi-annual event has been conducted regularly since 2006 with the aim of confronting a decline in the interest among girls to study IT and promoting study and work opportunities in the field. Each event has been evaluated with pre- and post-event surveys. Longitudinally, both students and teachers have also been surveyed three to four years after the event in which they participated. Results from the 2006 cohort surveyed in 2009-2010 are reported on in this paper. The main conclusion is that, unfortunately, any increase in the uptake of IT in schools that occurred as a result of attending the event was transitory. Therefore, it is crucial that inspiring, engaging, and empowering computing classes are being offered continuously at all secondary schools.
