Wetlands are among the most important ecosystems on Earth both in terms of productivity and biodiversity, but also as a source of the greenhouse gas CH4. Microbial processes catalyzing nutrient recycling and CH4 production are controlled by sediment physico-chemistry, which is in turn affected by plant activity and the foraging behaviour of herbivores. We performed field and laboratory experiments to evaluate the direct effect of herbivores on soil microbial activity and their indirect effects as the consequence of reduced macrophyte density, using migratory Bewick’s swans (Cygnus columbianus bewickii Yarrell) feeding on fennel pondweed (Potamogeton pectinatus L.) tubers as a model system. A controlled foraging experiment using field enclosures indicated that swan bioturbation decreases CH4 production, through a decrease in the activity of methanogenic Archaea and an increased rate of CH4 oxidation in the bioturbated sediment. We also found a positive correlation between tuber density (a surrogate of plant density during the previous growth season) and CH4 production activity. A laboratory experiment showed that sediment sterilization enhances pondweed growth, probably due to elimination of the negative effects of microbial activity on plant growth. In summary, the bioturbation caused by swan grazing modulates CH4 cycling by means of both direct and indirect (i.e. plant-mediated) effects with potential consequences for CH4 emission from wetland systems.

The objective is to identify and test regulatory options for creating supportive environments for physical activity and healthy eating among local governments in Victoria, Australia. A literature review identified nine potential areas for policy intervention at local government level, including the walking environment and food policy. Discussion documents were drafted which summarized the public health evidence and legal framework for change in each area. Levels of support for particular interventions were identified through semi-structured interviews conducted with key informants from local government. We conducted 11 key informant interviews and found support for policy intervention to create environments supportive of physical activity but little support for policy changes to promote healthy eating. Participants reported lack of relevance and competing priorities as reasons for not supporting particular interventions. Promoting healthy eating environments was not considered a priority for local government above food safety. There is a real opportunity for action to prevent obesity at local government level (e.g. mandate the promotion of healthy eating environments). For local government to have a role in the promotion of healthy food environments, regulatory change and suitable funding are required.

The purpose of this paper is to examine the impact of an alternative ownership/control structure of corporate governance on firm performance. Specifically, we investigated the governance system of government linked companied (GLCs) in Malaysia. In this paper, we examine governance mechanism and firm performance of Malaysian GLCs and non-GLCs over a 11 year period from 1995 to 2005. We only select a sample of companies which are listed in Main Board. We chose a sample of 210 firms. We used Tobin’s Q which is an indicator of market performance is used as a proxy for company’s performances; meanwhile ROA is used to determine accounting performance. This paper is to determines whether after controlling firm specific characteristics such as corporate governance, agency cost, growth, risk and profitability, GLCs perform better than non-GLCs. Findings highlight that non-GLCs performance is better GLCs in term of corporate governance, and other firm specific characteristics. The relationship between ownership structure and firm performance has been issue of interest among academics, investors and policy makers as one of key issues in understanding the effectiveness of alternative governance systems where government ownership serves as a control mechanism.
I don't know anyone that has two drinks a day : young people, alcohol and the government of pleasure

Problematic alcohol consumption is a major public health, health education and health promotion issue in Australia and internationally. In an effort to better understand young people's drinking patterns and motivations we investigated the cultural drivers of drinking in 14–24 year-old Australians. We interviewed 60 young people in the state of Victoria aged 20–24 about their drinking biographies. At the time of interviewing, the draft guidelines on low-risk drinking were released by the National Health and Medical Research Council, Australia, and we asked our participants what they knew about them and if they thought they would affect their drinking patterns. Their responses indicate that pleasure and sociability are central to young people's drinking cultures which is supported by a range of research. However, O’Malley and Valverde claim that pleasure is silenced and/or deployed strategically in neo-liberal governance discourses about drugs and alcohol such as these guidelines which raises questions about the limits of such discourses to affect changes in drinking patterns.

Food policy interventions are an important component of obesity-prevention strategies and can potentially drive positive changes in obesogenic environments. This study sought to identify regulatory interventions targeting the food environment, and barriers/facilitators to their implementation at the Australian state government level. In-depth interviews were conducted with senior representatives from state/territory governments, statutory authorities and non-government organizations (n = 45) to examine participants’ (i) suggestions for regulatory interventions for healthier food environments and (ii) support for pre-selected regulatory interventions derived from a literature review. Data were analysed using thematic and constant comparative analyses. Interventions commonly suggested by participants were regulating unhealthy food marketing; limiting the density of fast food outlets; pricing reforms to decrease fruit/vegetable prices and increase unhealthy food prices; and improved food labelling. The most commonly supported preselected interventions were related to food marketing and service. Primary production and retail sector interventions were least supported. The dominant themes were the need for whole-of-government and collaborative approaches; the influence of the food industry; conflicting policies/agenda; regulatory challenges; the need for evidence of effectiveness; and economic disincentives. While interventions such as public sector healthy food service policies were supported by participants, marketing restrictions and fiscal interventions face substantial barriers including a push for deregulation and private sector opposition.

A case study is used to demonstrate the application of Geographical Information Systems (GIS) to inform sustainable development. The suitability of the landscape to support tourism accommodation in a Local Government Area (LGA) is modelled by integrating existing datasets, including conservation areas, residential zones, major roads and known locations of tourism operators into a logistic regression framework. By using a data-driven approach an indication of the relative importance of each explanatory variable can be accounted for, therefore informing planners of the importance of different assets. In a region where tourism is reliant upon natural features, this use of information systems in conjunction with quantitative statistical modelling can value-add to existing datasets. The provision of this kind of knowledge is important as it would otherwise not factor into the decision-making process had the datasets been considered independently of each other – a concept that applies to both the public and private sectors.

This article is a study of the Chifley government's foreign policy towards Asia, in particular India and Indonesia, as evidenced by Australia's attendance at the 1947 Asian Relations Conference and the 1949 New Delhi Conference on the Indonesian-Dutch conflict. Australia's presence at these two conferences provides an ideal opportunity to examine the Chifley government's response to the momentous changes that occurred in post-war Asia as a result of the dismantling of the European colonial world order. Through detailed examination of the archival material and contemporary accounts generated from Australia's involvement in the New Delhi conferences, this article will argue that despite significant political constraints, the Chifley government did adopt a distinctive and innovative policy towards the emergent nations of Asia in the immediate post-war years.

While the role of religion in Australian schools has been vigorously debated since the 1870s, it has recently generated considerable controversy, particularly in the State of Victoria. Despite the Victorian Government’s positive record of promoting multifaith engagement, Christian volunteers – provided by ACCESS Ministries - currently teach 96% of students enrolled in Special Religious Instruction (SRI) classes in Victoria’s Government schools.
