Introduction and Aims The aim of this study was to determine changes in advertising expenditures across eight media channels for the four main alcohol beverage types and alcohol retailers in Australia. Design and Methods Yearly advertising expenditures between January 1997 and December 2011 obtained from a leading media-monitoring company. Media channels assessed were: free-to-air television, newspapers, magazines, radio, outdoors (billboards), cinema, direct mail (from 2005) and online (from 2008). Data were categorised into alcohol retailers (e.g. supermarkets, off-licences) or four alcoholic beverage types (beer, wine, spirits, premixed spirits/cider). Regression analyses examined associations between year and expenditure. Results Total alcohol advertising expenditure peaked in 2007, then declined to 2011 (P = 0.02). Television advertising expenditure declined between 2000 and 2011 (P < 0.001), while outdoor advertising expenditure increased between 1997 and 2007. Alcohol retailers' advertising expenditure increased over time (P < 0.001), and from the mid-2000s exceeded expenditure for any single beverage category. For both beer and spirits, television advertising expenditure declined over time (beer: P < 0.001; spirits: P < 0.001) while outdoor advertising expenditure increased (beer: P < 0.001; spirits: P = 0.02). However, the number of advertised beer (P < 0.001), spirits (P < 0.001) and wine (P = 0.01) products increased over time. Discussion and Conclusions Retailers are playing an increasing role in advertising alcohol. As our study excluded non-traditional advertising media (e.g. sponsorships, in-store) we cannot determine whether declines in television advertising have been offset by increases in advertising in newer media channels. However, our findings that media channels used for alcohol advertising have changed over time highlights the need for adequate controls on alcohol advertising in all media channels.

Substantial structural reform has occurred in the water and wastewater sectors of Australia's major urban centers over the past two decades. This reform has involved the corporatization of government assets and some vertical and horizontal separation. This paper analyses the performance of these sectors since the mid 1990s. In particular, it uses Malmquist Data Envelopment Analysis (DEA) to determine the different levels of productivity and efficiency improvement over this period. The results point to modest, but positive productivity gains in the larger urban centers, independent of industry structure. Further, it highlights the need to consider exogenous factors that can influence productivity outcomes in an industry generally associated with monopoly characteristics and dependent on water sources that are, to varying extents, unpredictable and uncontrollable.

Over the past decade, major landscape wildfires (or ‘bushfires’ in Australia) in fire-prone countries have illustrated the seriousness of this global environmental problem. This natural hazard presents a complex mesh of dynamic factors for those seeking to reduce or manage its costs, as ignitions, hazard behaviour, and the reactions of different human and ecological communities during and after hazard events are all extremely uncertain. But while those at risk of wildfire have been subject to significant research, the social dimensions of its management, including the role of science, have received little attention. This paper reports on a case study of the Barwon-Otway area of Victoria in Australia, a high wildfire risk area that has recently been a pilot site for a new risk mitigation strategy utilising the wildfire simulation model PHOENIX RapidFire. Against simple equations between ‘more science’ and ‘less uncertainty,’ this paper presents results from interviews and a workshop with practitioners to investigate how scientific research interacts with and informs both wildfire policy and practice. We suggest that attending to cultural and social specificities of the application of any technical innovation—such as next generation modelling—raises questions for future research about the roles of narrative, performance, and other knowledges in the sedimentation of science.

Eight teacher educators used self-study methodology to engage in reflective practice to overcome their isolation as individual teachers and researchers, and to facilitate professional development. Their research question asked: How can we continue to develop our teaching practice to ensure we are high quality, contemporary teacher educators? They contributed collaboratively in one overarching research project as well as through several focussed projects that explored issues in their individual teaching practices including: sustainability, creativity, curriculum design, pedagogy, assessment, and the learning experiences for students. This paper explores the outcomes from collaborative inquiry that five of the eight educator/researchers engaged in during a research-writing retreat. It documents their experience using arts-based strategies in which drawings were created about their experiences of engaging in a collaborative project and smaller focussed self-study projects. Analysis involved inquiring into each other’s drawings through recorded conversation. The metaphoric representations found through analysing the drawings provided insight into participants’ teaching practices and identities as teacher educators. Six months later when the participants had developed their projects further and used other artsbased methods to understand these experiences, they reflected on the key issues for their teaching practices that had arisen from undertaking this Collaborative Reflective Experience and Practice in Education research. Arts-based inquiries and reflective analysis over six months, constitute this paper. The experiences and analyses are shared to show how creating and sharing metaphoric meaning of visual representations is useful in self-study research to drill down into the real issues. Importantly, this in-depth sharing provides authentic interdisciplinary links when individual educators share their own approaches to teaching in their disciplined area. Findings suggest that gaining new insights into each other’s discipline-based approaches to teacher education through these methods, revealed different responses to pedagogical challenges and allowed for new possibilities for understanding the landscape of teacher education.

This paper presents data from a study of five English primary schools. It examines some of the challenges associated with school autonomy and collaboration for state primary schools amid the uncertainty and complexity of governance in the present English education context. The paper features the voices of six leaders gathered from interviews that explored their thoughts about the academies movement. It highlights their fears that academisation, and particularly the imperative to join a large academy chain, will undermine their autonomy as individual schools. Accepting of the inevitability of academisation and the forms of network governance this reform offers, it highlights the head teachers’ moves to ensure their autonomy in terms of determining the timing and type of conversion. In relation to these moves, the paper reiterates the significance within effective collaboratives of member schools experiencing a sense of ownership, a common purpose, shared responsibility for students and their learning and relations of trust. The paper considers some of the tensions arising in this space in relation to competition, collaboration and school vulnerability.

Parents’ perceptions of their neighbourhoods are important for child health outcomes. This study compared views among mothers in inner versus outer suburbs of Melbourne, Australia using a mixed methods approach. Mothers of preschool-aged children were recruited via playgroups, mother’s groups and preschools and interviewed face-to-face regarding their local area as a good place to raise a family, with a second open-ended interview focussing on mothers’ ideals and experiences of raising children in their current location. Findings demonstrated that mothers had different ideals for, and experiences of, raising their children in their neighbourhoods. Inner suburban mothers valued a manageable work/family balance and access to public transport over the size of their homes. However, access to childcare, secondary schooling and heavy traffic were issues, with the latter two being reasons for moving from the municipality. In contrast, outer suburban mothers preferred a larger home in neighbourhoods that they perceived as low crime, over accessibility to work. Access to a car and activities for their children were also important. Findings suggest no ‘one size fits all’ in respect to what features mothers expect from a good place to raise a family, or how they experience these features. This has implications for service delivery and social planning of suburbs.
