Research on children and youth increasingly features young people's photographs and/or young people as photographers. While this suggests that quite a lot is known about young people's relationships to photographs and camera technologies, this is not the case. Following an overview of studies that engage with young photographers, this article demonstrates why still very little is known about young people's photographic practices – that is, the range of ways and media through which young people take, feature in, and use photographs. The author argues that this gap in knowledge needs to be addressed. Important aspects of childhood, youth and growing up, including identity, belonging and memory, are often experienced and/or expressed in part through photographs and photography.  相似文献

Abstract

Does occupation-level information reflect what people actually do at work and thus influence individuals? I examine whether there is an effect of occupation-level complexity on individuals' sense of personal control, and if there is, whether the effect is a proxy for the actual work people do on their jobs. I analyze a national probability sample of 1,450 employed persons interviewed by telephone in 1995. Without adjustment for worker's reports of autonomy, creativity, authority, and social interaction in their daily work, an index of DOT occupational complexity of work with data and people correlates with the sense of personal control. Adjustment for job-level autonomy, creativity, authority, and social interaction renders the occupation-level measure insignificant and shows significant effects of autonomous work, creative work, and social interaction at work on the sense of personal control.  相似文献

Non-nested hypothesis tests provide a way to test the specification of an econometric model against the evidence provided by one or more non-nested alternatives. This paper surveys the recent literature on non-nested hypothesis testing in the context of regression and related models. Much of the purely statistical 1iterature which has evolved from the fundamental work of Cox (1961, 1962) is discussed briefly or not at all. Instead, emphasis is placed on those techniques which are easy to employ in practice and are likely to be useful to applied workers.  相似文献

The police profession is one in which acute stressors are encountered more frequently than in other occupations. Using the personal accounts of 35 police officers attending an in-house stress counselling clinic, the aim of the present study was to provide a qualitative examination of how the institutional context of policing influenced the ways in which acute stressors signified to individual police officers experiencing felt distress. Using the framework of Rational Emotive Behaviour Therapy as an analytical tool, it is argued that beliefs contributing to the experience of felt distress are related to the way in which policing as both an identity and an activity is constructed through the police organizational culture. Not only do these constructions influence the ways in which officers perceive themselves and their environments, but they also operate at the collective level to 'normalize' some emotional responses and to 'pathologize' others which, it is argued, could impact upon the outcomes of interventions such as stress counselling.  相似文献

Activists in seven US cities were interviewed about why they thought people in their communities mobilized against alcohol-related problems. The data were analyzed in light of the focus on resource mobilization theory in the social movement literature. In contrast with claims that resources are the primary catalyst for change, informants emphasized the role of grievances, and to a lesser extent, bridging factors that caused residents to be more aware of or frustrated by problems, and thus ready for change. Resources seemed to provide necessary but insufficient conditions for explaining movement participation, suggesting that, to be effective, resources must be channeled to address and be linked to the grievous social conditions of inner city communities.  相似文献

A doctoral student approached the column editor and suggested that an update on a “The Balance Point” column entitled “The One-Box Challenge: Providing a Federated Search That Benefits the Research Process” (2006) would be of interest and useful to readers, and the editor agreed. Contributors to the original column were asked to reflect upon their experiences with federated searching, including successes and failures over the past 10 years, and to provide insights into future challenges and issues. This edition of “The Balance Point” focuses on the ongoing challenges, lessons learned, possible future directions, and issues involved in providing one-box searching to library patrons.  相似文献
