This retrospective study investigates 79 lesbian, gay, bisexual, and transgender (LGBT) college students’ experiences attending high schools with gay-straight student alliances (GSAs). Responses to two, open-ended survey questions were analyzed thematically to identify reasons that underlie GSA non-membership and to model facets of GSAs that may impact the GSA-related experiences of LGBT youths. Three frames of reference for understanding GSA non-membership and perceptions of GSAs emerged. Implications for predicting GSA membership and identifying protective mechanisms of GSAs are outlined. Suggestions to help GSA leaders and advisors enhance specific aspects of GSAs that appear to be associated with positive perceptions of GSAs are also provided.  相似文献

文化因素的多元性,往往会造成个体身份认同的矛盾与紧张,但孔子的身份认同却实现了多元文化因素的统一.孔子在周是殷人后裔,在鲁则是宋的移民,但他对周文化及鲁国存在强烈的认同.孔子是传统的继承者,同时又并不排斥新兴礼俗.孔子为恢复周代礼制四处奔走,是一位积极的入世者,同时又能欣赏出世隐者的生命态度.孔子的"仁道"理念,是他消解不同文化因素之间的冲突、实现个体身份认同多元文化相互统一的根本依据.在"仁道"基础上,"用中"的方法,为孔子的身份认同提供了重要的文化选择模式.  相似文献

The present study examines Hong Kong citizens’ willingness to participate in the Occupy Central/Umbrella Movement. A representative adult survey (N = 816) was conducted before the Occupy Central protest in 2014. Regression analyses showed that the core psychological antecedents of political identity (psychological attachment to pro-democracy parties and Occupy activists), political efficacy (perceived effectiveness of individual and movement agency), ideology (dissatisfaction with the pace of democratization), and emotion (anger with the political environment) were significant predictors of likely participation. Measures of perceived effectiveness of the Occupy movement to achieve successful outcomes (i.e. its ability to influence public opinion, strengthen the pro-democracy cause in Hong Kong, and facilitate opinion expression) explained additional variance even after controlling for demographics and the core antecedents. An integrated motivational model of collective action was then tested using structural equation modeling. Findings are consistent with the extant literature. Moral convictions (democracy as a fundamental human value) served as an antecedent of identity, efficacy, ideology, and anger, while identity exhibited direct and indirect effects on participation through efficacy, ideology and anger. The model also pointed to a role for perceived effectiveness, supporting the idea that individuals are motivated by other potential outcomes of a protest beyond achieving its primary objective.  相似文献

Fisher's Linear Discriminant Function Can be used to classify an individual who has sampled from one of two multivariate normal Populations. In the following, this function is viewed as the other given his data vector it is assumed that the Population means and common covariance matrix are unknown. The vector of discriminant coeffients β(p×1) is the gradient of posterior log-odds and certain of its lineqar functions are directional derivatives which have a practical meaning. Accordingly, we treat the problems of estimating several linear functions of β The usual estimatoes of these functions are scaled versions of the unbiased estmators. In this Paper, these estimators are domainated by explicit alterenatives under a quadratic loss function. we reduce the problem of estimating β to that of estimating the inverse convariance matrix.  相似文献

This paper analyzes the new names given to Russian private businesses that have appeared after the collapse of the Soviet State in 1991. By naming new private ventures their owners members of the new business class attempt to privatize public space not only legally but also symbolically and linguistically. They strive to construct their particular new version of social reality, to represent it as positive and meaningful, and to impose themselves publicly as legitimate authors, owners, and masters of this new reality. This paper proceeds on several distinct levels of analysis. First, it analyzes a number of discourses, representing various subcultures and periods of Soviet and Russian history, from which new business names draw their complex meanings. Second, it considers concrete linguistic and semiotic techniques that are employed by the new names in this process. Third, it examines the cultural and social implications of this process of nomination for post-Soviet developments in the Russian society.  相似文献

Prior research highlights the role of friends in influencing whether a student completes high school. Students who drop out tend to have fewer friends, as well as friends who are less oriented toward school success. We distinguish between close and distant friendships by developing a theoretical framework which predicts close and distant friends likely have distinct effects on dropping out. Close friendships provide valuable emotional support, and forging numerous close friendships at school should decrease one’s risk of dropping out. In contrast, the characteristics of distant friends help shape students’ social identities and beliefs about “what’s normative.” Our analyses of the Add Health data set confirm our expectations. Students with more close friendships are less likely to drop out, but close friends’ characteristics are unrelated to dropping out. Distant relationships (as measured by affect and regularity of interaction) with friends who have a high risk of dropping out significantly increase a student’s own risk of dropping out.  相似文献

SUMMARY

This essay uses an academic letter format to address the topic of fatherhood through the personal perspective of a single, middle-aged, multi-ethnic, gay man. After providing auto-ethnographic reflections of childhood and family life, a survey of influential popular cultural texts and academic literature on fatherhood and parenting is provided. Finally, the letter ends with an in depth examination of the international film Bear Cub/Cachorro, along with concluding auto-ethnographic reflections and thoughts on the author's readiness and desire to become a father.  相似文献
