Pieces of silver : examples of the economic impact and management of the silver gull (Larus novaehollandiae) in Melbourne, Australia

Like a number of gull species, the silver gull Larus novaehollandiae has expanded its population in response to human food subsidy. The major anthropogenic food source is food waste at rubbish tips. Other sources of human food waste are also exploited. Many problems result from the activities of these birds, including human health and safety, economic impacts, and effects on the conservation of other species. My study examines aspects of the economic impacts of the silver gull on the human community of the Greater Melbourne Area comprising approximately 4065 km2 (1569 square miles). My data collection method involves identifying sites where problems have been experienced and completing questionnaires during face to face interviews with the managers of those sites. Data collected at this early stage of the study demonstrate that there are significant, quantifiable economic impacts associated with the superabundance of the silver gull in this area. Other impacts, such as reduced amenity and potential health hazards are equally real but more difficult to quantify. Costs include damage to structures and products, damage prevention measures, and loss of production. Information about the costs of these problems will be presented to the relevant landfill management authorities to encourage them to consider alternative means of disposing of putrescible waste, rather than by open landfill disposal, because even current best practice management of open landfill sites (rubbish tips) provides ample opportunity for silver gulls and certain other bird species to exploit this food source. Controlling access by the silver gull to food at rubbish tips would be an important first step in managing the population of this species.

Net energy analysis of solar and conventional domestic hot water systems in Melbourne, Australia

It is commonly assumed that solar hot water systems save energy and reduce greenhouse gas emissions. Very rarely has the life-cycle energy requirements of solar hot water systems been analysed, including their embodied energy. The extent to which solar hot water systems save energy compared to conventional systems in Melbourne, Australia, is shown through a comparative net energy analysis. The solar systems provided a net energy saving compared to the conventional systems after 0.5 to 2 years, for electricity and gas systems respectively.

Tradition as past is a modernist idea

As outlined in the theme of this conference, the problematisation of the notion of 'progress' relates to a questioning of the West's teleological aspirations for the future. This critique has allowed for the presence of a multiplicity of ways of perceiving the world, including those from outside the West's intellectual tradition. However, within architectural discourse, conceptual plurality has been largely limited to movements such as critical regionalism or postmodernism, which have tended to question the direction or desirability of progress, rather than its fundamental nature.

This paper looks at an example of recent architecture by an Asian diasporic community in Melbourne. This is a building that appears to be 'traditional' in style, in other words atavistic and antithetical to 'progressive' architectural ideals. However, looking at it through different philosophical understandings of duration can provide us with alternative interpretations to these assumptions.

By this I am not referring to disillusionment with progress, as expressed through postmodernist and neo-traditionalist movements in the West, but ways in which looking at the 'traditional' architectures of non-Western cultures from their own philosophical positions might provide alternative definitions pf the idea of 'progress'. The increasing presence of non-western 'traditional' architecture in the West implies that West modernity might not be the only 'tradition' that has a viable future. Consequently, the idea of 'the future' as something to aspire to, might be the outcome of a particular dominant historicity rather than a universal condition.

Community valuations of historic pocket parks: a Melbourne study

The internal reserve, an historic form of planned open space creating semi-private parks at the rear of residential allotments and without street frontages, can be found in Australian suburban areas of diverse socio-economic status. Internal reserves commonly express the idealism of the early town planning movement, which envisaged the internal reserve as an embedded community-building mechanism with multiple potential uses. En vogue from 1910-1930, the internal reserve concept proved problematical from the outset. Even today, while many residents agree that their reserves are responsible for the special nature of their domestic environment, others are apprehensive about safety, maintenance and custodianship. Two surveys of residents living around internal reserves in four Melbourne suburbs, conducted in 1979 and 2002, reveal a variety of opinions on the potential and importance of these spaces. Local communities were found for the most part to have negative and ambiguous perceptions of these reserves. With one exception, residents did not value the parks highly as community spaces and alternative uses may need to be explored. The results suggest that a more innovative set of tools and incentives may be needed to reinvigorate the internal reserve as a significant recreation resource for local communities.

A new relationship between planning and democracy? Urban activism in Melbourne 1965-1975

This paper is a reflective overview of urban social protest in the years 1965-1975 and its influence on post-war planning, especially on models of public participation in planning, and conceptions of effective local democracy. Drawing extensively on a major study of urban activism in Melbourne, Australia, the paper discusses the political and organisational strategies used by activists in Melbourne’s inner city areas to resist the large-scale planning/urban renewal projects especially of the Victorian state government. The paper focuses on Melbourne’s inner city Residents’ Action Groups and examines their motivations, strategies and rationales, placing them within an international context of urban protest movements demanding local democracy and consultation. The paper concludes that the Melbourne urban protest movements of the late 60s and early 70s deserve recognition for their contribution to inclusive, consultative processes in planning decision-making. This is done within a context of questioning contemporary academic discussion around the interpretative concept of gentrification, widely and indiscriminately applied to this and later periods of urban change.

The square from inside out: Federation Square, Melbourne

This XXlst Annual Conference of SAHANZ offers a timely opportunity for celebrating and critically reflecting on Federation Square, Melbourne - a project that continually crosses the line between the purely experimental and the built form (A Benjamin, 2003) and offers an opportunity to identify and investigate the different, often competing, limits within the discipline of architecture. Here in this project, considered by the city of Melbourne to point to its future aspirations; and by the RAIA as demonstrating 'the strength of design and the leap into the unknown which is where good design always comes from' (I McDougall, 2003), different approaches to the possibilities of 'limit' as a contemporary concern can be fruitfully explored. Architectural masterpieces are daringly imaginative and each in their own way challenges architects, engineers, builders and technologists - those who are to realise the dream - and makes administrators, politicians and governments put their credibility on the line. So how does Federation Square contribute to contemporary architectural debate, specifically to Melbourne architecture? How has it dealt with thresholds? Where has It approached, crossed and/or exceeded boundaries? This paper will deal with design aesthetics in the realisation of the Lab architects 'vision' in the context of historical, urban and political realities. Analysis will provide insights into the limitations imposed upon this architectural project and the limitations it now, in turn, imposes on the city. Two aspects will be dealt with: understanding Lab's overall vision, and juxtaposing the vision with the reality of Federation Square. The author's interview with Don Bates, principal Lab architecture studio, forms the frame argument about Federation Square in this paper.

The first 50 years of the annual endowed accounting research lecture series at the University of Melbourne

Carnegie and Edwards (2001) suggest that the formation of an organisational body is just one of the 'signals of movement' within the dynamic process of professionalisation of an occupation and they list the sponsoring of professorial posts and research activities at universities as further examples. While the literature on this process in Australia does refer to the sponsorship of chairs of accounting (Carnegie & Williams, 2001), little has been written identifying the range of other areas of sponsorship by the organised accounting bodies. This paper presents details of the first fifty years presentations of the Annual Accounting Research Lectures held at The University of Melbourne, Australia. They have been presented continuously since 1940, when they were inaugurated with sponsorship from the Commonwealth Institute of Accountants. The paper presents the first complete listing of details relating to the presenter (including name, gender, residency and occupational area), title of the paper, date of presentation (where known) and details of publication (where appropriate). The initial and subsequent motivation for the presentation of the series and the influence of the lectures in promoting research and fostering relations between the professional bodies and the university, during a period of great significance in the development of accounting education and the professionalisation of accounting in Australia, is also discussed.

Leveraging the Commonwealth Games in Melbourne for community engagement: an examination of Equal First and the Adopt-a-Second-Team program

Event leverage provides information about what outcomes occur as a result of an event. Unlike event impact studies, event leverage analysis identifies why particular outcomes occurred, and the processes that can be used to optimise desired event outcomes. While research has been directed towards understanding how events can be leveraged to provide optimal economic outcomes for host communities, there is little research that examines social leverage within the context of events. The research presented in this paper is part of a larger study that investigated social leverage within the context of the 2006 Commonwealth Games, held in Melbourne, Australia. This paper presents preliminary results relating to two Victorian regions with regard to one the over-arching social policy, Equal First, and a subsidiary program called, Adopt-a-Second-Team. Participant observations and stakeholder interviews were employed to explore the development, operationalisation, implementation and outcomes of Equal First and Adopt-a-Second-Team. The results suggest that although each region achieved outcomes that were consistent with the directions of Equal First, each implemented the Adopt-a-Second-Team differently. The two case studies presented in this paper highlight that the model of implementation developed by the City of Port Phillip may provide a benchmark in social leverage of events. Implications for leveraging social impacts and managing social legacies of events through an approach that includes consideration of policy development and operationalisation from the event organising body and program implementation from the perspective of local community event organisers are discussed.
