Popular culture, the 'victim' trope and queer youth analytics

This article offers a joint reading of two cultural texts that reflect the contest over victim-oriented characterizations of queer youth in contemporary culture. The first text is a representation of queer youth taken from the popular UK television series Shameless (2004). The second text is an online discussion about representations of gay and lesbian characters on television that was recently posted on the Queer Youth Network website. Through my reading of these two texts, I explore the rise of explicit mainstream representations of gay and lesbian characters and the emergence of an identifiable queer youth audience as key characteristics of the contemporary 'after-queer' moment. Through a reflection on the queer youth analytical techniques observable on the Queer Youth Network site, I conclude by outlining some key implications for future educational research in the field of youth, sexuality and popular culture.

Knowledge sharing through virtual layers in regional sustainable development networks

Our research examines how the organisational structure facilitates knowledge sharing within the group. This case study examines a Victorian regional sustainable group using interviews and social network analysis to identify the group’s organisational structure and its effect on knowledge sharing between the members. Our findings indicate that while the mixed membership, lack of hierarchy and layered structure are complex, these elements work together to provide members with a rich body of knowledge. The diversity and differences in membership are complimentary and combined can provide a more in-depth understanding of the regional sustainable development issues.

Emphasizing 'the relational self' as a goal in casework

Traditional and radical authors agree that strengthening the autonomy of service users is a primary aim in casework. The current paper seeks to balance this emphasis on individual autonomy by arguing that the relational aspects of the self also require attention. This argument proceeds in three steps. Firstly, recent theoretical work will be introduced to advance the premise that the self can be understood as ‘relational’ as well as ‘autonomous’. Secondly, a summary is offered of the research which concludes that a strong social network, or in the more recently favoured terms, that ‘social connectedness’ and ‘attachment’, is protective of health and well-being. Building on these two ideas, it is then suggested that it may be important for caseworkers to promote the quality of interdependence and connectedness of those service users with whom we work, irrespective of the presenting problem and the practitioner’s preferred method and assigned practice role.

Gen Y and their 'backpacks of hidden treasures'

This paper reports on part of a teacher/researcher’s PhD action research study conducted in an Australian public high school, investigating the use of online social networking as a classroom learning environment where students were encouraged to find and use their hidden treasures. It examines student reactions and online activity whilst they are interacting with a range of Web 2.0 and social media tools. The study may inform the rising generation of higher education learners and their course developers and explores the move from passive to active learning through Gen Y’s engagement with online social media. It looks at a range of innovative practices that were made possible through using a Ning online social network as a classroom environment whilst encouraging Gen Y to take more responsibility for learning. It also looks at the pedagogical implications that come with the use of social media as they challenge traditional models of ‘instructional order’. This study primarily adopts a social constructivist approach to teaching with the focus being on learning, rather than teaching. The study found that having such a flexible curriculum environment encouraged Gen Y to share their ‘hidden treasures’ and, hence, informal classroom learning became more visible and more readily documented. Gen Y students appreciated the opportunities to publish and to gain feedback from more than their teacher alone. Students, in some cases, could be seen to be engaged in their own cycle of learning where they valued the opinion of their peers which, in turn, helped them to improve their work.

Exploring the potential of knowledge brokering to enhance natural resource management : findings from the Catchment Knowledge Exchange project in Victoria

Despite significant efforts in natural resource management (NRM), the environmental condition of Victoria’s catchments is mostly ‘poor to moderate’, and continuing to decline in many places. NRM is a complex undertaking involving social, economic, and environmental objectives, across policy, research, and practice dimensions. It is therefore not easy to ensure that the knowledge required to underpin effective NRM is readily available to practitioners. Knowledge brokering is an emerging approach with the potential to improve knowledge sharing and exchange. While it has attracted attention in other areas of public interest (such as health and information technology), its potential in NRM has received relatively limited attention. This article reports on a Victorian knowledge brokering case study which was a major element in the Catchment Knowledge Exchange project. A key finding is that knowledge brokering is a role that is being undertaken informally, without proper acknowledgement or definition. This raises challenges for knowledge management in the context of NRM. We conclude that the ‘people’ component of knowledge brokering is the driving element, although organisational processes and information technologies are critical in enhancing the effectiveness of knowledge brokers. Demonstrating the benefits of knowledge brokering in terms of the ultimate measure of its contribution towards improving the condition of catchments remains a challenge.

Hyper-community detection in the blogosphere

Most existing work on learning community structure in social network is graph-based whose links among the members are often represented as an adjacency matrix, encoding direct pairwise associations between members. In this paper, we propose a method to group online communities in blogosphere based on the topics learnt from the content blogged. We then consider a different type of online community formulation - the sentiment-based grouping of online communities. The problem of sentiment-based clustering for community structure discovery is rich with many interesting open aspects to be explored. We propose a novel approach for addressing hyper-community detection based on users' sentiment. We employ a nonparametric clustering to automatically discover hidden hyper-communities and present the results obtained from a large dataset.

"They all work...when you stick to them" : a qualitative investigation of dieting, weight loss, and physical exercise, in obese individuals

Background
To explore the extent to which people living with obesity have attempted to lose weight, their attitudes towards dieting, physical exercise and weight loss solutions, why their weight loss attempts have failed, and their opinions about what would be most beneficial to them in their struggle with their weight.

Method
Qualitative study, using open-ended interviews, of 76 people living with obesity in Victoria, Australia in 2006/7. Individuals with a BMI of 30 or over were recruited using articles in local newspapers, convenience sampling, and at a later stage purposive sampling techniques to diversify the sample. Data analysis was conducted by hand using a constant, comparative method to develop and test analytical categories. Data were interpreted both within team meetings and through providing research participants the chance to comment on the study findings.

Results
Whilst participants repeatedly turned to commercial diets in their weight loss attempts, few had used, or were motivated to participate in physical activity. Friends or family members had introduced most individuals to weight loss techniques. Those who took part in interventions with members of their social network were more likely to report feeling accepted and supported. Participants blamed themselves for being unable to maintain their weight loss or 'stick' to diets. Whilst diets did not result in sustained weight loss, two thirds of participants felt that dieting was an effective way to lose weight.

Conclusion
Individuals with obesity receive numerous instructions about what to do to address their weight, but very few are given appropriate long term guidance or support with which to follow through those instructions. Understanding the positive role of social networks may be particularly important in engaging individuals in physical activity. Public health approaches to obesity must engage and consult with those currently living with obesity, if patterns of social change are to occur.

Towards an improved understanding of knowledge dynamics in integrated coastal zone management: a knowledge systems framework

Integrated coastal zone management (ICZM) is a complex undertaking that draws on a range of biophysical and social science disciplines, and involves a wide range of stakeholders operating through multiple processes, and crossing various levels  Conceptually, this means that ICZM represents a significant challenge in terms of improving the way in which different disciplinary ‘knowledges’ and different forms of knowledge (scientific, managerial, lay, and indigenous) inform decision making. Depending upon the circumstances, ICZM may be constrained by different knowledge deficits, including: uncertainty; science - policy gaps; and the ‘filtering’ of particular forms of knowledge relative to others. As a means for making sense of these knowledge dynamics, this paper considers the concept of knowledge systems and its potential for improving understanding of coastal management processes. The potential insights that can be gained from four analytical approaches (stakeholder, institutional, network, and discourse analysis) are then discussed, and used to develop an analytical framework for investigating coastal knowledge dynamics, which is based upon a generic coastal knowledge system and associated research questions. Finally, the utility of this framework is illustrated using a case study that examines the knowledge dynamics associated with debates about the establishment of marine protected areas in Victoria, Australia.

An education in Facebook

For some years academics have debated the role in higher education of Facebook, the world’s most extensive social networking site. At first there was enthusiasm—it was a new tool that could be ‘repurposed’ for education; then, as Facebook became more widespread, its use seemed less than opportune. But now, with so many students already engaged before they even come to a university, perhaps it is impossible to avoid the conclusion that Facebook is as natural to education as the commute, the computer, and everything else which students ‘bring’. This paper first presents a summary of what Facebook affords, by way of its design and use, for online communication and networking, demonstrating the central role of reciprocal acts of attention exchange in this system. It then analyses, through a critical reading of research into Facebook and education, the way Facebook challenges traditional understandings of university education and the relationships between teachers and students. It concludes that, however we might seek to use Facebook in higher education (and there are many reasons we might), its use will always be shaped by—and indeed give rise to—a blurring of the traditional boundaries between formal and informal education.

Developing online construction technology resources in tectonic design education

We outline issues of importance in relation to tectonic design within the architectural profession and the relationship to architectural education in Australia. Twelve years of research and curriculum development at Deakin University is discussed, involving the creation of online resources and case studies, digitally-integrated projects relating to building construction and design studio education. The ethos behind the Construction Primer of engaging students as ‘amateur researchers’ in a way that ensures ‘that student research work is worth more than course assessment’ forms the pedagogical foundation of much of this work. A model of Socially Networked Construction Technology education has been developed that integrates social networks and the Internet to engage students in tectonic design within and outside the classroom through authentic curricula. Through the use of Virtual Galleries, Blogs, YouTube and social networks, a culture of peer learning and sharing has been developed. Through shared knowledge facilitated through social networks, great potential lies for expanding the synergies between higher order learning and online resource development for design decision support.

Ghosts in the machine : do the dead live on in Facebook?

Of the many ways in which identity is constructed and performed online, few are as strongly ‘anchored’ to existing offline relationships as in online social networks like Facebook and Myspace. These networks utilise profiles that extend our practical, psychological and even corporeal identity in ways that give them considerable phenomenal presence in the lives of spatially distant people. This raises interesting questions about the persistence of identity when these online profiles survive the deaths of the users behind them, via the practice of ‘memorialising’ social network profile pages. I situate these practices within a phenomenology of grief that accounts for the ways in which the dead can persist as moral patients, and show how online survival in this case illuminates an important difference between persons and selves within contemporary philosophy of personal identity. Ultimately, the online persistence of the dead helps bring into view a deep ontological contradiction implicit in our dealings with death: the dead both live on as objects of duty and yet completely cease to exist.

Trust evaluation for indirectly connected nodes using link community information

Inspired by recent empirical research on link communities, we borrow some important ideas and concepts for our own research to provide a more reasonable computation model of transitive trust. The key advantages of using link community methodology is to reflect on the nature of the social network features of Hierarchy and Overlap. Our research mainly resolves the computation of trust transitivity in which two nodes do not have any direct links to any link community. In this research, we discover a new direction analyzing trust transitivity. By using a social network game, we found that the link community methodology is a natural way to analyze trust in social networks. We also discovered, even in a small social network, trust has certain community features.

Twitter free Iran: an evaluation of Twitter's role in public diplomacy and information operations in Iran's 2009 election crisis

Social media platforms such as Twitter pose new challenges for decision-makers in an international crisis. We examine Twitter’s role during Iran’s 2009 election crisis using a comparative analysis of Twitter investors, US State Department diplomats, citizen activists and Iranian protestors and paramilitary forces. We code for key events during the election’s aftermath from 12 June to 5 August 2009, and evaluate Twitter. Foreign policy, international political economy and historical sociology frameworks provide a deeper context of how Twitter was used by different users for defensive information operations and public diplomacy. Those who believe Twitter and other social network technologies will enable ordinary people to seize power from repressive regimes should consider the fate of Iran’s protestors, some of whom paid for their enthusiastic adoption of Twitter with their lives.

Cooperative and competitive structures of trust relations in teams

This article argues that it is not just trust-generating but also trust-inhibiting mechanisms that operate in teams, and that these cooperative and competitive structures of interpersonal relations of trust within teams may affect team performance. Specifically, we propose that the presence of trust-generating structures (e.g., reciprocity, trusting in the referrals of others we trust, trusting in high performers and more experienced people) and the absence of trust-inhibiting structures (e.g., not trusting in the referrals of others we trust) are more likely to be associated with successful teams. Using exponential random graph models, a particular class of statistical model for social networks, we examine three professional sporting teams from the Australian Football League for the presence and absence of these mechanisms of interpersonal relations of trust. Quantitative network results indicate a differential presence of these postulated structures of trust relations in line with our hypotheses. Qualitative comparisons of these quantitative findings with team performance measures suggest a link between trust-generating and trust-inhibiting mechanisms of trust and team performance. Further theorization on other trust-inhibiting structures of trust relations and related empirical work is likely to shed further light on these connections.
