Contextual gaps: privacy issues on Facebook

Social networking sites like Facebook are rapidly gaining in popularity. At the same time, they seem to present significant privacy issues for their users. We analyze two of Facebooks’s more recent features, Applications and News Feed, from the perspective enabled by Helen Nissenbaum’s treatment of privacy as “contextual integrity.” Offline, privacy is mediated by highly granular social contexts. Online contexts, including social networking sites, lack much of this granularity. These contextual gaps are at the root of many of the sites’ privacy issues. Applications, which nearly invisibly shares not just a users’, but a user’s friends’ information with third parties, clearly violates standard norms of information flow. News Feed is a more complex case, because it involves not just questions of privacy, but also of program interface and of the meaning of “friendship” online. In both cases, many of the privacy issues on Facebook are primarily design issues, which could be ameliorated by an interface that made the flows of information more transparent to users.     

Emotional responses to documentary viewing and the potential for transformative teaching

This paper examines the relationship between specific documentaries and white student teachers’ emotional responses to their viewing as part of a postgraduate teacher education course on educational equality. Documentaries are considered in terms of features (including elements of text), form (including stylistic conventions) and function in order to evaluate those elements most important in involving students emotionally. It argues that certain documentaries have the pedagogic potential to transform student thinking via the evocation of particular emotions which act to disturb white hegemonic practices, attitudes and cognitions. However, given that emotion is understood as integral to the operationalisation of whiteness, students’ emotional responses are analysed from a critical whiteness perspective to reveal emotion as also potentially obstructive to student transformation. Hence, the paper shares the pedagogic decisions taken to capitalise on those emotional responses conducive to transformed student understandings and to stymie those which act as investment in whiteness to impede student development. Finally, it is argued that a conceptual lens is vital for understanding the relationship between documentaries and emotional responses in order that transformed thinking is enabled.     

The Place of English Revisited

In this essay I explore the constraints and opportunities confronting me as a newly qualified teacher and how these affect my pedagogy. I have reflected on my own development from beginning to newly qualified teacher and considered how such forces have shaped my identity as a teacher, my values and my approach to the job. As part of my exploration of my practice and the values I hold, I have revisited ‘The Place of English’, an essay I wrote midway through my Postgraduate Certificate in Education (PGCE) year; I have reconsidered how the current climate of educational reform and my subsequent experience have altered or strengthened these initial perceptions. In what follows I have reflected critically on two episodes of teaching and learning with my Year 10 class, my most challenging group, in order to further understand the way in which I have responded to the responsibilities and pressures placed on a classroom teacher. These pressures, I suggest, are intensified by the preconceptions of age and gender within my school and implicit more widely in the traditional values of our culture. The fragments of my practice that I have explored reveal tensions that gesture at a gap between educational theory, first-hand professional experience and governmental policy. They present an argument to resist the temptations of oversimplified, linear conceptions of teaching and learning, and maintain the place of English as a subject of creativity, exploration and expression that, at its heart, values both individual and collective student voices and identities.     

A single session of resistance exercise does not reduce postprandial lipaemia

This study investigated the effect of a single session of resistance exercise on postprandial lipaemia. Eleven healthy normolipidaemic men with a mean age of 23 (standard error = 1.4) years performed two trials at least 1 week apart in a counterbalanced randomized design. In each trial, participants consumed a test meal (1.2 g fat, 1.1 g carbohydrate, 0.2 g protein and 68 kJ x kg(-1) body mass) between 08.00 and 09.00 h following a 12 h fast. The afternoon before one trial, the participants performed an 88 min bout of resistance exercise. Before the other trial, the participants were inactive (control trial). Resistance exercise was performed using free weights and included four sets of 10 repetitions of each of 11 exercises. Sets were performed at 80% of 10-repetition maximum with a 2 min work and rest interval. Venous blood samples were obtained in the fasted state and at intervals for 6 h postprandially. Fasting plasma triacylglycerol (TAG) concentration did not differ significantly between control (1.03 +/- 0.13 mmol x l(-1)) and exercise (0.94 +/- 0.09 mmol x l(-1)) trials (mean +/- standard error). Similarly, the 6 h total area under the plasma TAG concentration versus time curve did not differ significantly between the control (9.84 +/- 1.40 mmol l(-1) x 6 h(-1)) and exercise (9.38 +/- 1.12 mmol x l(-1) x 6 h(-1)) trials. These findings suggest that a single session of resistance exercise does not reduce postprandial lipaemia.     

African American preschool children's physical activity levels in Head Start

The purpose of this study was to describe the physical activity levels of urban inner city preschoolers while attending Head Start, the federally funded preschool program for children from low-income families. Participants were 158 African American children. Their physical activity during Head Start days was measured using programmed RT-3 accelerometers. Results revealed that the children spent the most time in sedentary and light physical activity, while their participation in moderate-to-vigorous physical activities was low. Given the sedentary class format and limited physical space for the Head Start programs observed, we suggest adding a structured physical activity component to Head Start schools to fight the overweight and obesity crisis.     

Exploring the Usefulness of Kelly's Personal Construct Theory in Assessing Student Learning in Science Courses

We explore the utility of George Kelly's Personal Construct Theory, specifically his repertory grid technique, to the assessment of student learning in undergraduate science courses. We provide an in-depth review of the assumptions underlying Personal Construct Theory and how these were reflected in the repertory grid technique Kelly developed. We explain how an adapted version of the repertory grid, sharing some yet not all of Kelly's assumptions, was utilised as a research tool in a recent study involving science instructors and their students. We argue that as well as having applicability as an innovative research tool, an adapted version of Kelly's repertory grid is a useful heuristic for university teachers when used as a classroom assessment technique (CAT) and indicate several features it shares with the more widely-known conceptual mapping technique, which has been used in the study of science teaching and learning for many years. We conclude by highlighting several advantages the use of repertory grids has for both students and instructors.     

Working with ‘Diverse Bodies,Diverse Identities’: an approach to professional education about ‘diversity’

The complexity and diversity of populations in contemporary Western societies is becoming a significant public policy issue. The concept of ‘diversity’ has come to represent cultural, ethnic, racial and religious differences between the ‘dominant group’ and immigrant and indigenous populations. ‘Diversity training’ is amongst many strategies being implemented to address social and economic objectives in complex societies. This paper discusses and critically evaluates a professional education programme, ‘Diverse Bodies, Diverse Identities’, that is offered to human service practitioners and social work students in Victoria, Australia. It is concluded that a range of approaches is needed to address ‘diversity’ in contemporary societies.
