Contextual gaps: privacy issues on Facebook     

Gordon Hull  Heather Richter Lipford  Celine Latulipe 《Ethics and Information Technology》2011,13(4):289-302

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   

Examining the influence of the parent-initiated and coach-created motivational climates upon athletes' perfectionistic cognitions     

Appleton PR  Hall HK  Hill AP 《Journal of sports sciences》2011,29(7):661-671

The aims of this study are threefold. First, we investigate the influence of the parent-initiated motivational climate upon elite junior athletes' perfectionistic cognitions. Second, we examine whether the coach-created motivational climate predicts additional variance in elite junior athletes' perfectionistic cognitions beyond the effects associated with the parent-initiated motivational climate. Third, we test the moderating role of athletes' gender and age in the relationship between the parent-initiated and coach-created motivational climates and athletes' perfectionistic cognitions. A total of 190 elite junior athletes (mean age 15.2 years, s?=?1.5, range 10-18) completed the Parent-Initiated Motivational Climate Questionnaire-2 (White & Duda, 1993), the Perceived Motivational Climate in Sport Questionnaire-2 (Newton, Duda, & Yin, 2000), and the Perfectionistic Cognitions Inventory (Flett, Hewitt, Blankstein, & Gray, 1998). Regression analyses revealed that mother- and father-initiated worry-conducive climates, the father-initiated success-without-effort climate, and the coach-created performance motivational climate predicted male athletes' perfectionistic cognitions. Female athletes' perfectionistic cognitions were predicted by the mother-initiated worry-conducive climate, father-initiated learning-enjoyment climate, and both dimensions of the coach-created climate. Finally, athletes' gender emerged as a significant moderator of the mother-initiated worry-conducive climate and athletes' perfectionistic cognitions relationship. Findings confirm that the parent-initiated motivational climate is a significant predictor of athletes' perfectionism-related thoughts, and provide initial support for the influence of the coach-created motivation climate over children's perfectionistic cognitions.  相似文献   

Emotional responses to documentary viewing and the potential for transformative teaching     

Heather J. Smith 《Teaching Education》2014,25(2):217-238

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   

The Place of English Revisited     

Heather Wood 《Changing English: An International Journal of English Teaching》2014,21(1):3-13

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

The Right to Teach, the Right to Learn     

Laurie Bush  Tony Hill 《British Journal of Special Education》1993,20(1):4-7

Believe that the findings and recommendations of the Elton Committee have much to offer schools for children with emotional and behavioural difficulties, as well as mainstream schools. They outline the way they have introduced 'assertive discipline' into behaviour management policy of the school.  相似文献   

Reliability of No Child Left Behind Accountability Designs     

Richard K. Hill  Charles A. DePascale 《Educational Measurement》2003,22(3):12-20

The No Child Left Behind Act of 2001 requires states to establish accountability systems that are both valid and reliable. If one follows the language of the law literally, there is no design that will meet both requirements. If one interprets the law more flexibly, it is possible to create such a design. States will need to approach the problem carefully if they are going to appropriately balance the various probabilities of making incorrect decisions about schools.  相似文献

A single session of resistance exercise does not reduce postprandial lipaemia     

Burns SF  Corrie H  Holder E  Nightingale T  Stensel DJ 《Journal of sports sciences》2005,23(3):251-260

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.  相似文献
