The potentials and pitfalls of social networking sites such as Facebook in higher education contexts

Popular social networking sites such as Facebook demonstrate an emerging opportunity for students and educators within formal higher education contexts to share ideas, celebrate creativity and participate in an environment which offers immediate feedback from others who belong within a specific network. As this is an emerging use of the technology, an autoethnographic approach has helped capture the potentials and pitfalls of incorporating social networking within higher education. The findings highlight implications for the key stakeholders in higher education.

Extraction of latent patterns and contexts from social honest signals using hierarchical Dirichlet processes

A fundamental task in pervasive computing is reliable acquisition of contexts from sensor data. This is crucial to the operation of smart pervasive systems and services so that they might behave efficiently and appropriately upon a given context. Simple forms of context can often be extracted directly from raw data. Equally important, or more, is the hidden context and pattern buried inside the data, which is more challenging to discover. Most of existing approaches borrow methods and techniques from machine learning, dominantly employ parametric unsupervised learning and clustering techniques. Being parametric, a severe drawback of these methods is the requirement to specify the number of latent patterns in advance. In this paper, we explore the use of Bayesian nonparametric methods, a recent data modelling framework in machine learning, to infer latent patterns from sensor data acquired in a pervasive setting. Under this formalism, nonparametric prior distributions are used for data generative process, and thus, they allow the number of latent patterns to be learned automatically and grow with the data - as more data comes in, the model complexity can grow to explain new and unseen patterns. In particular, we make use of the hierarchical Dirichlet processes (HDP) to infer atomic activities and interaction patterns from honest signals collected from sociometric badges. We show how data from these sensors can be represented and learned with HDP. We illustrate insights into atomic patterns learned by the model and use them to achieve high-performance clustering. We also demonstrate the framework on the popular Reality Mining dataset, illustrating the ability of the model to automatically infer typical social groups in this dataset. Finally, our framework is generic and applicable to a much wider range of problems in pervasive computing where one needs to infer high-level, latent patterns and contexts from sensor data.

Elite girls' schooling, social class and sexualised popular culture

Young women’s identities are an issue of public and academic interest across a number of western nations at the present time. This book explores how young women attending an elite school for girls understand and construct ‘empowerment’. It investigates the extent to which, and the ways in which, their constructions of empowerment and identity work to overturn, or resist, key regulations and normative expectations for girls in post-feminist, hyper-sexualised cultural contexts. The book provides a succinct overview of feminist theorisations of normative femininities in young women’s lives in western cultural contexts. It includes familiar sexist discourses such as sexual double standards, as well as more recent commentary about the regulation of young women’s subjectivities in neoliberal, post-feminist, hyper-sexualised cultures. Drawing on ethnographic research in the context of an elite girls’ secondary school, the author explores how empowerment for young women is constructed and understood across a range of textual practices. From visual representations of young women in school promotional material, to students’ constructions of popular celebrities, the question of how girls’ resistance to normative femininities begins to develop is examined. This rich empirical work makes a unique contribution to the study of elite schooling within the sociology of education, drawing on important insights from the field of critical girlhood studies, and posing a challenge to popular feminist notions about media literacy, young women and empowerment. It will be of interest to scholars and postgraduates in the areas of gender studies, sociology, education, youth studies and cultural studies.

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.

Young adolescents' perceptions, patterns, and contexts of energy drink use. A focus group study

Caffeinated energy drinks (EDs) are purported to increase energy and improve performance, but have been associated with adverse health effects and death. EDs are popular among adolescents and young adults, yet little is known about their use among young adolescents. This study explored perceptions, patterns, and contexts of ED use in six focus groups with 40 adolescents aged 12-15 years from two regional Australian schools. A thematic analysis of the data was used to investigate knowledge about ED brands and content, ED use, reasons for ED use, physiological effects, and influences on ED use. Participants were familiar with EDs and most had used them at least once but had limited knowledge of ED ingredients, and some had difficulty differentiating them from soft and sports drinks. EDs were used as an alternative to other drinks, to provide energy, and in social contexts, and their use was associated with short-term physiological symptoms. Parents and advertising influenced participants' perceptions and use of EDs. These findings suggest young adolescents use EDs without knowing what they are drinking and how they are contributing to their personal risk of harm. The advertising, appeal, and use of EDs by adolescents appear to share similarities with alcohol and tobacco. Further research is needed to replicate and extend the current findings, informed by the lessons learned in alcohol research.

Still in the LEGO (LEGOS) room : female teachers designing curriculum around girls’ popular culture for the coeducational classroom in Australia

While the issue of boys’ dominance of the curriculum has a long history, the article examines this phenomenon in a contemporary context, through an empirical study with female teachers designing English curriculum around girls’ media in a coeducational secondary school in Victoria, Australia. In this space, teachers, and the researcher, produce and perform both individual gendered identities and plans for the identities of future student subjects, while negotiating subject positions made available to girls and women in broader social contexts. In this instance, negotiations that take place during the development of a unit of work on Mattel's Barbie website form the basis of feminist discourse analysis, enabling us to ‘take stock’ in thinking about what curriculum design is, about where the past is situated in relation to the present, and to question why, within a discursive feminist/postfeminist entanglement, the heritage of feminist intellectual thought in this area seems absent.

Pop art: making mathematics popular

Leicha Bragg shares an effective activity for integrating visual arts, technology and mathematics. Such an approach has the potential to enhance students' visual reasoning and spatial ability by using multiple perspectives of learning. 

Popular culture/sacredness

A huge billboard faces me as I crawl down Punt Road Melbourne, its wild purple and yellow-daubed sports fan (male) leering over the northbound traffic. Its message: 'Sport is a Religion, so pray for Yamaha Stadium Sound'  Canny advertising, hooking into aussie culture, selecting an aussie take on religion/ sport (fun, serious, primitive, fanatic, central). Next, there's the Next fashion ad, with its larger than life-sized photograph of a gorgeously dressed young female eying off the pope's long white robe, comparing outfits. Fashion as religion, or better than, really, is the inference-she looks mildly
amused, and he looks a little nonplussed. And then there are the many Qantas advertisments for 'Spirit of. Australia' featuring Aboriginal figures, with backdrops of Dlum and the red desert. As cultural tour businesses know, there's money to be made in taking urban, nonIndigenous tourists to visit their 'spiritual other', the Aboriginal.1 Or there's the multicultural, children's version of the ad, with all the little global travellers of the future featured in wonderful locations. Spirit of Australia.

The behavioural and demographic contexts of white bread consumption

The aim of this study was to examine the demographic, health habits and personal values associations of white bread use. A total of 474 randomly selected consumers completed a questionnaire about bread consumption, health habits and personal values. The findings showed that compared with non-consumers white bread users were younger, less educated, more likely to have children and to be smokers. They were less likely to follow vegetarian, low fat or special diets or use alternative therapies. Non-consumers were more likely to hold pro-nature universalistic values. This suggests that the use of this staple food is associated with demographic, behavioural and ideological domains. Their causal inter-relationships require further investigation.

Restructuring educational leadership in changing contexts: a local/global account of restructuring in Australia

The 1990s saw considerable structural reform in school education in many Anglophone nation states, marked by trends towards school-based, site-based, self-managing and self-governing schools. This article illustrates through a case study of educational restructuring in Victoria, Australia, how leadership, as a discursive practice, is redefined in the context of spatial and cultural restructuring. Restructuring produced a spatial redistribution of educational provision and individual opportunities as a result of structural adjustment reforms. These same policy moves towards post-welfarism also produced cultural shifts in attitudes to education with the rise of the new instrumentalism and entrepeneurialism. For school principals at the forefront of self managing schools, this meant shifts in resource distribution through new policy mechanisms of managerial and market accountability, and also new priorities impacting on leadership practices with a move from dialogic to decisional modes of management. The question is how recent policy moves towards learning networks and reinventing systematic support with a focus on locational disadvantage are addressing what were increased educational disparities between schools and students. Does this provide scope for more equity-driven leadership practices?

The Fiftieth Gate : an Australian case study in twentieth-century 'popular' publishing

On Sunday 6 April 1997, historian Mark Baker's first non-academic book was launched at Melbourne's iconic migrant portal, Station Pier. The guest list of over 500 invitees included representatives of many print media organisations, most of whom interviewed the author. His photograph was reproduced a week later in the 'Agenda' section of The Age newspaper. In this portrait, Baker leans on the railings beside the massive structure of Station Pier. Framed by sea and sky, he is caught glancing pensively over his shoulder past the camera and into the middle distance. He is alone. The day is bleak. Here, the reader is invited to surmise, is a man with much on his mind. In a flash of inspiration the sub-editor has prefaced the accompanying caption, 'Back to the future', linking the story with the mass media of film and television.

Children's participation in music : connecting the cultural contexts - an Australian perspective

The cultural contexts of home, school and community all have important parts to play in the music education of children, but at present in Australia, these three entities are insufficiently connected on a number of fronts, not the least being an understanding about the purpose(s) of young people's engagement with music. This paper puts forward two specific proposals for action aimed to help build linkages among the three cultural contexts and ensure young people's on-going engagement with music. These proposals, which call on the education sector to assume leadership for action, have implications for policy makers, school personnel, as well as parents, individual artists and community arts organisations.
