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. 相似文献

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. 相似文献

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. 相似文献

ABSTRACT Cities in the United States and across the world have experienced gentrification at the same time as school choice policies have become more popular. This research examines the relationship between gentrification and charter schooling, seeking to understand how together they affect demographic composition of schools across Washington, DC. This study uses geographic information systems (GIS) mapping and statistical techniques to show that gentrified neighborhoods are more likely to have charter schools. Additionally, the demographic compositions of charter schools and traditional public schools differ depending on the gentrification classification of the census tract in which the schools are located. While a handful of diverse charter schools exist in gentrified neighborhoods and some diverse public schools exist in traditionally affluent neighborhoods, schools in Washington, DC remain racially and economically isolated overall. 相似文献

It has been 20 years since Robert J. Bursik Jr. published his seminal article outlining some of the problems and prospects in the social disorganization perspective on crime and delinquency. In this study, we review the content of approximately 200 published articles that cite Bursik’s 1988 piece. These studies are systematically examined in terms of their efforts to overcome the problems and pursue the prospects that Bursik outlined. In addition to content analysis, we survey the authors who cite this work. That is, we gather data from the authors directly to assess the influence of Bursik’s article on their own published work. Our research finds that Bursik’s work played a significant role in the revitalization and expansion of social disorganization theory. 相似文献

The Connexions service has particular responsibility for coordinating transition planning for students with learning difficulties. In this study Bob Grove and Alison Giraud–Saunders report on the development of the personal adviser (PA) role in two special schools and an FE college as part of the Lewisham Connexions pilot. This article is based on the evaluation report of the Connecting with Connexions project, which is available in full from the authors. 相似文献
