While school-based adolescent victimization has received a great deal of public attention, there exist relatively few theoretically driven studies aimed at explaining this phenomenon. We address this paucity by providing a test of a criminal-opportunity model of school-based victimization using data on over 3,000 students from 40 different Kentucky middle and high schools. The effects of opportunity-related concepts are estimated for both violent and property victimization, and comparisons are made for each victimization type across middle- and high-school student subsamples. Findings suggest that criminal opportunity theory is relevant to the understanding of school-based victimization. In particular, indicators of exposure to crime and target antagonism appear to be robust predictors. Further, there appears to be substantial generalizability in the effects of opportunity-related variables across violent versus property victimization as well as across middle-school versus high-school contexts. 相似文献

A research agenda for the black middle class: work stress, survival strategies, and mental health 总被引:1,自引:0,他引:1
In this article we discuss the social position of the black middle class and two forms of work stress that appear unique to this group: token stress and social rejection. We outline a research agenda for studying: (1) the relationship between these stressors and mental health in the context of the work environment, and (2) the type of strategies that appear especially efficacious (or problematic) with regard to these problems. We begin the paper with a contextual discussion of the black middle class. We then offer a set of theoretical predictions about the relationship between work stress and mental health among middle class African Americans. We conclude the article with recommendations for future research, and we identify the implications of the research agenda for social policy efforts to diversify the workplace. 相似文献

This study explores how online publics are engaging with organizations by creating and sharing brand-related content online, outside corporate-controlled communication environments. This research employs a quantitative content analysis of memes shared on the social networking site Imgur to reveal how user-generated content conveys meaning about organizations. The analysis reveals brand-centric memes are generally classified as orphan memes, or memes that have distinct textual and visual characteristics separating them from established or emerging meme families. Memes about organizations are neither an overwhelming reflection of biting criticism or support, but rather a reflection of online public engagement with organizations that primarily use humor and textual brand features (or quiddities) to convey their commitment and satisfaction with the organization and unite meme families. 相似文献

In a clinical trial comparing drug with placebo, where there are multiple primary endpoints, we consider testing problems where an efficacious drug effect can be claimed only if statistical significance is demonstrated at the nominal level for all endpoints. Under the assumption that the data are multivariate normal, the multiple endpoint-testing problem is formulated. The usual testing procedure involves testing each endpoint separately at the same significance level using two-sample t-tests, and claiming drug efficacy only if each t-statistic is significant. In this paper we investigate properties of this procedure. We show that it is identical to both an intersection union test and the likelihood ratio test. A simple expression for the p-value is given. The level and power function are studied; it is shown that the test may be conservative and that it is biased. Computable bounds for the power function are established. 相似文献
