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.

Scaling connectionist compositional representations

The Recursive Auto-Associative Memory (RAAM) has come to dominate connectionist investigations into representing compositional structure. Although an adequate model when dealing with limited data, the capacity of RAAM to scale-up to real-world tasks has been frequently questioned. RAAM networks are difficult to train (due to the moving target effect) and as such training times can be lengthy. Investigations into RAAM have produced many variants in an attempt to overcome such limitations. We outline how one such model ((S)RAAM) is able to quickly produce context-sensitive representations that may be used to aid a deterministic parsing process. By substituting a symbolic stack in an existing hybrid parser, we show that (S)RAAM is more than capable of encoding the real-world data sets employed. We conclude by suggesting that models such as (S)RAAM offer valuable insights into the features of connectionist compositional representations.

Negotiating agents that learn about others’ preferences

In multiagent systems, an agent does not usually have complete information about the preferences and decision making processes of other agents. This might prevent the agents from making coordinated choices, purely due to their ignorance of what others want. This paper describes the integration of a learning module into a communication-intensive negotiating agent architecture. The learning module gives the agents the ability to learn about other agents’ preferences via past interactions. Over time, the agents can incrementally update their models of other agents’ preferences and use them to make better coordinated decisions. Combining both communication and learning, as two complement knowledge acquisition methods, helps to reduce the amount of communication needed on average, and is justified in situation where communication is computationally costly or simply not desirable (e.g. to preserve the individual privacy).

The human bridge

Two of the ideas taken into collaborative groups emerging within the workshop symposia were: 1. models of collaboration and 2. notions of the gift and gift economy. This research addressed the idea of stepping on other to progress. And asks the question as to how whether one will literally step on another person and how one handles this delicate proposition when confronted with it the notion of putting their weight on the bodies of several people lying on the ground. In this performance, several people lie on the floor blocking access to a entrance way. Persons wishing to enter the space for activities in the community hall, must walk over the person lying on the floor. Two assistants advise, guide and encourage persons entering the hallway if they request or look in need of assistance traversing the human bridge.

Myopia : why study the mechanisms of myopia? Novel approaches to risk factors Signaling eye growth- how could basic biology be translated into clinical insights? Where are genetic and proteomic approaches leading? How does visual function contribute to an

On July 26–29, 2010 the 13th International Myopia Conference was held in Tübingen, Germany and included 17 separate symposia, each with 3–5 presentations. Here, in a single paper, the chairs of those Symposia describe the scientific advances noted at the conference and include the full abstracts of the individual myopia papers presented in each symposium along with the authors and their institutions. The 17 Symposia covered 7 topics: Why Study the Mechanisms of Myopia?; Novel Approaches to Risk Factors; Signaling Eye Growth- How Could Basic Biology Be Translated into Clinical Insights?; Where Are Genetic and Proteomic Approaches Leading?; How Does Visual Function Contribute to and Interact with Ametropia?; Does Eye Shape Matter?; Why Ametropia at All?

The Popular Education Network of Australia (PENA) and Twenty-First-Century critical education

Drawing on the philosophies and writings of Paulo Freire regarding education as activism, this paper will explore the history and activities of the Popular Education Network of Australia (PENA). The network, founded in 2009, involves educators, academics and community workers, working together on issues relating to critical pedagogy and social change in schools, communities and adult education contexts. Two symposia have been organised on critical education in Australia. In 2010, ‘Teaching and Learning for Social Justice and Action’ was the inaugural gathering. In 2012, ‘Freire Reloaded: Learning and Teaching to Change the World’ featured a diverse range of workshops and Professor Antonia Darder as keynote speaker and observer. Through the perspectives and experiences of five academics involved in PENA, this paper will explore the group’s activities and reflect on the inspiration drawn from the work of Freire, Darder and others. Creating spaces for discussion of critical pedagogy affords opportunities for academics, educators, teachers and activists to reflect on their practice and also leads to further spontaneous networking and planning of action. In this paper we argue that there is continuing importance, in fact urgency, in producing places and spaces for conscientisation to occur, and for examples of critical education to be shared amongst 21st century educators.

Organizational Fit: Key Issues and New Directions

An ambitious survey of the field, by an international group of scholars, that looks toward the future of person-organization fit. Explores how people form their impressions of fit and the impact these have on their behavior, and how companies can maximize fit. Includes multiple perspectives on the topic of how people fit into organizations, discussing issues across the field and incorporating insights from related disciplines. Actively encourages scholars to take part in organizational fit research, drawing on workshops and symposia held specially for this book to explore some of the creative directions that the field is taking into the future. © 2013 John Wiley & Sons, Ltd.
