Describes the decreasing prevalence of physical activity participation over the young adult years and the patterns of difference in the physical activity habits of young men and young women. Physical activity habits during the young adult years are likely to be important influences on habitual physical activity during overall adult life and, consequently, have significant implications for long-term health outcomes. Tertiary-education campuses are settings where there exist important yet partially neglected opportunities to influence the physical activity habits of young adults. Uses examples from Australia and the USA are used to characterise relevant contextual and practical aspects of the campus setting and the physical activity promotion opportunities that it may provide. Reviews findings from two campus-based physical activity intervention studies. In conclusion, identifies a set of issues that require further research.

In this paper, I provide evidence of policy 'backlash' against feminism from the standpoint of the practitioner. When asked, in a case study of Victorian primary schools how the gender inclusive curriculum was conceptualised and enacted, practitioners critique the conservative policy shift that they observed. I premise this paper on the notion that critical reflection on the specificities of policy discourse from the previous decade represents transformative work for the contemporary policy context. I conclude with a discussion of how research agendas in the current era of uncertainty can be re-assessed in the light of this study.

Hypocaust systems, where conditioned or non-conditioned air is passed through ducts within the concrete floor or ceiling of a building prior to its delivery to the rooms, are starting to appear in new buildings in Australia.

This paper describes the lessons that can be learned from the early experiences with a hypocaust system, installed in a new building in Melbourne. It concludes that a more cooperative process between all those involved in introducing and using a new 'technology' is essential if the problems described are to be avoided or at least minimized.

The National Review of School Music Education represents a unique opportunity to identify and find solutions to some of the very long-standing problems in Australian school music education, particularly in the government school sector. This paper is based on the premise that there are lessons to be learned from the over 150 years of music education in Victorian government schools and that it is only by considering the current status, provision and quality of school music from an historical perspective and resolving emergent issues that effective and worthwhile music education can be provided for future generations of Australian students. Developments in school music education since the 1850s are discussed and analysed in terms of the present-day issues to be addressed by National Review and a number of mutually-dependent factors are identified as combining to produce almost cyclic patterns of ebb and flow in the status, provision and quality of music education in Victoria. The paper identifies several such factors requiring immediate attention including the inadequacy of generalist primary teacher education in music, what has effectively become the extra-curricular status of music in many government schools, and the more recent problems associated with 'the over-crowded curriculum' and the emergence of The Arts as the generic Key Learning Area in which Music now finds itself as just one of many arts disciplines. The paper concludes by making three key recommendations for consideration in the context of the current National Review of School Music Education.

In this paper, we analyse the case for agricultural land retirement in Australia. For the case study considered, using defined criteria, we demonstrate that land retirement is an effective policy option. This finding depends crucially on the magnitude and sign of the price effect resulting from a fall in wool production because of agricultural land retirement. Uniquely in the literature, we argue that the price effect will positively contribute to a benefit–cost analysis of agricultural land retirement. We detail the necessary conditions that need to prevail for this to occur. We also explain why the expected benefits of land-use change are fewer than might be expected in the case study.

Developing tools for measuring progress toward sustainability has proven a challenging task. Indicators offer an excellent means to explore the success or otherwise of management strategies. They also allow reporting social, economic and environmental aspects of sustainability. To ensure that the tools developed are effective in measuring the progress toward sustainable futures, an evaluation of the methods and the indicators used must be undertaken so that with progress there is learning and with the new knowledge methods can be redesigned to better advance sustainability. This paper discusses a study carried out in the south west region of Victoria, Australia, using indicators as the basis for developing a tool to measure progress toward sustainability. By evaluating the methods and indicators used in the study this paper provides an insight into the challenges encountered and the lessons learned. Issues explored include selecting indicators, collating data, integrating social, economic and environmental aspects of sustainability and using an adaptive approach.

Performance management introduced to the senior health executive levels in the New South Wales public health care system included the senior executive service in 1989 and, as a key element of that service, performance agreements in 1990. This is the first qualitative study examining senior health executives' personal experiences of these changes. In consideration of what has been learnt from the most relevant literature and this study, this paper concludes that the introduction and implementation performance management is a continuous process. This process includes the key steps of planning, measuring, monitoring and evaluating. It can be used as a means to achieve overall effective organisation performance by bringing in a two way management process for the organisation and its senior health executives.

Issue addressed: Mental health promotion aimed at populations with low socio-economic status (SES) may benefit by investigating prevention strategies that effectively address related child and adolescent problems.
Methods: Evidence from a number of literature reviews and program evaluations was synthesised. First, the impact of SES on development from childhood to adulthood is considered in light of research on substance
abuse, violence, crime, and child development problems. Second, evaluations of interventions are reviewed to identify those that have shown outcomes in research studies (efficacy) or in real-world settings (effectiveness) in reducing developmental problems associated with low SES. Low SES is measured in different ways including low levels of education and/or income or definitions that combine several variables into a new indicator of low SES.
Results: Factors associated with low SES are also associated to varying extent with the development of violence and crime, substance abuse and child health problems. Interventions that address underlying determinants of low SES show strong efficacy in decreasing adolescent crime and violence and effectiveness in improving child health outcomes. Although there is limited efficacy evidence that substance abuse prevention can be effectively addressed by targeting low SES, programs designed to improve educational pathways show some efficacy in reducing aspects of adolescent substance use.
Conclusion: Mental health promotion strategies can draw on the approaches outlined here that are associated with the prevention of child and adolescent problems within low SES communities. Alternatively, such interventions could be supported in mental health promotion policy as they may assist in preventing related problems that undermine mental health.
