ABSTRACT We applied the selection, optimization and compensation (SOC) model of successful aging to media use. Using a new self-report measure to assess selective and compensatory media use we illustrate the role of these media selection strategies in successful aging. In other words, we link compensatory and selective media use to different indicators of well-being among older nursing home residents and for a group of younger adults, which served as a comparison group. Selective media use was positively related to well-being for older, but not for younger adults, and compensatory media use was negatively related to well-being for both younger and older adults. In a second study, we replicated these findings with a sample of healthy older adults. 相似文献

This article considers the extent and nature of student participation in a trade bargaining simulation from a community of practice perspective. This third‐year economics module included a blend of online communication (through email, online chats and online discussions) and face‐to‐face meetings, both in smaller bargaining groups and in whole class plenary meetings. Our method of analysis includes the use of Exchange Structure Analysis of text chats and face‐to‐face learning conversations, triangulated by observation, survey and interview data. The focus on community of practice enables us to offer a nuanced interpretation of differences in crude participation data derived from the online chats. Superficially, the data may suggest marginalisation of participants, but Wenger's (1988 ) notion of peripheral participation with a trajectory towards full participation reframes the disparities in terms of an active community of practice. Some members are fully engaged with the practices of trade bargaining from the early stages of the simulation, while others move towards full participation over the duration of the simulation. Our results suggest that the laboratory‐based online text chats did provide opportunities for student participation in the simulation, and that male and female students exhibited different patterns of participation in the chats. 相似文献

Cyberbullying is a repeated violent behavior aimed at hurting another person directed by an individual or a group towards the victim using technological means such as a computer or a mobile phone (Kowalski, Morgan, and Limber, 2012). The current study examined the phenomenon of cyberbullying among children and youth in Israel. The purpose of was to examine the correlation between bully and victim, and emotional-social aspects—social support, sense of loneliness and sense of self-efficacy—that constitute risk factors and protective factors. The study involved 1,094 elementary, middle school and high school students, who completed four questionnaires that addressed cyber-bullying and the social and emotional aspects: Social support, loneliness, self-efficacy and personal well-being. It was found that the less social support the students have, the lower their sense of self-efficacy; the lonelier they feel and the more they experience a lower sense of well-being, the greater the likelihood that they will participate in cyberbullying, mainly by sending offensive pictures or videos. 相似文献
