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

A sequence of independent, identically distributed random variables is considered. Given a simple local condition on the distribution of these random variables, we give necessary and sufficient conditions on the tails of the distribution for the moment generating function of a standardized quantile of the first n observations to converge to the moment generating function of an appropriate normal distribution as n →infinity;. This result is actually a special case of a more general result which can also be used to show convergence in distribution and convergence of moments of standardized quantiles. 相似文献

Let T be a random variable having an absolutely continuous distribution function. It is known that linearity of E(T | T > t) can be used to characterize distributions such as exponential, power and Pareto distribution. In this work, we will extend the above results. More precisely, we characterize the distribution of T by using certain relationships of conditional moments of T. Our results can also be used to obtain new characterization of distributions based on adjacent order statistics or record values. 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

This study uses natural, everyday social interaction within Salvadoran families living in Southern California to examine the use of the 2nd‐person singular pronouns tú and vos (and their corresponding morphologies) in this contact variety of Spanish. An in‐depth, qualitative analysis reveals that the employment and significance of these forms of address do not conform entirely to Salvadoran norms, nor to those of the surrounding Mexican‐based Spanish koiné. Accommodation to the pronominal repertoire of the region's majority serves as a communicative resource driven by questions of U.S./Los Angeles identity and solidarity with speakers in‐the‐moment interlocutor(s), a process which has caused the original Salvadoran pronouns to also be reallocated and refunctionalized (Britain and Trudgill 1999 ) as resources for accomplishing Salvadoran identity. Members of this community make active use of their pronominal options in real‐time interaction as they navigate the fluid, multifaceted identities that they and their interlocutors now embody in the U.S. context. 相似文献
