Electronic social communication has provided a new context for children to bully and harass their peers and it is clear that cyberbullying is a growing public health concern in the US and abroad. The present study examined individual and contextual predictors of cyberbullying in a sample of 16, 634 students in grades 3–5 and 7–8. Data were obtained from a large cluster-randomized trial of the KiVa antibullying program that occurred in Finland between 2007 and 2009. Students completed measures at pre-intervention assessing provictim attitudes (defined as children’s beliefs that bullying is unacceptable, victims are acceptable, and defending victims is valued), perceptions of teachers’ ability to intervene in bullying, and cyberbullying behavior. Students with higher scores on provictim attitudes reported lower frequencies of cyberbullying. This relationship was true for individual provictim attitudes as well as the collective attitudes of students within classrooms. Teachers’ ability to intervene assessed at the classroom level was a unique, positive predictor of cyberbullying. Classrooms in which students collectively considered their teacher as capable of intervening to stop bullying had higher mean levels of cyberbullying frequency. Our findings suggest that cyberbullying and other indirect or covert forms of bullying may be more prevalent in classrooms where students collectively perceive their teacher’s ability to intervene in bullying as high. We found no evidence that individual or contextual effects were conditional on age or gender. Implications for research and practice are discussed.  相似文献

Body surveillance and body shame are features of objectified body consciousness that have utility in predicting body image and eating disturbances but evidence is based largely on samples in developed Western nations and it is not clear whether these factors predict disturbances independent of conceptually-related factors emphasized in alternate sociocultural accounts. To address these issues, we assessed the impact of body surveillance and body shame as well as features of other sociocultural models (i.e. perceived appearance pressure, appearance comparisons, general negative affect) on disordered eating, fatness concerns, and body dissatisfaction among young Chinese adults. University-age women (n = 466) and men (n = 230) from Chongqing, China completed validated self-report measures of demographics and the above constructs. For women, objectified body consciousness measures explained significant variance in each measure of disturbances, beyond effects of other factors; body surveillance had a unique impact in each prediction model. For men, facets of objectified body consciousness also combined for unique variance across prediction models, though body shame was the more prominent unique influence. Findings highlight the potential role of individual differences in body surveillance and body shame as influences on eating and body image of young women and men within a Chinese context.  相似文献

The paper investigates changes in IMF activities using the analytical framework of international public goods. The IMF promotes international financial stability, whose outputs are joint products with varying degrees of publicness. In recent years, IMF loans (recipient-specific benefits) have assumed decreased importance, while the Fund’s technical assistance and monitoring activities have taken on greater importance. As a consequence, the club and purely public outputs (e.g., disseminating best practices) have grown as a share of IMF activities. Changes in the mix of IMF activities alter the mix of international public goods and, in so doing, change policy recommendations regarding the role of IMF. The future of IMF is also addressed, especially in light of increased private capital flows.

Both the East and Southeast China Seas have been home to a series of repeated episodes of tension between the People’s Republic of China (PRC) and its neighbors. Much of the existing literature either treats such episodes as isolated data points or as the manifestation of underlying structural factors. In this paper, we argue that repeated tensions can have important effects on subsequent interactions, generating emergent dynamics with dangerous consequences. What is more, we believe those dynamics to already be in play in several of the disputes within East Asia today. Examining recent developments in PRC-Japan and PRC-Philippines relations, we seek to shed light on how iterated episodes of tension are shaping the trajectory of interactions in both dyads. We believe these insights can inform efforts to understand relations in the region and beyond, given the growing frequency and intensity of repeated tensions among actors.  相似文献
