汶川地震给我国的经济和社会生活带来极大的影响,本文以“社会资本”作为切入点,分析社会资本在灾后恢复中的作用。微观社会资本可以提供非正式支持、影响民众的求助行为和缓解心理震痛,宏观社会资本可以提高公众参与程度、增强信任感和建立新的社会规范从而调动民众重建家园的积极性,在短时间内将损失降到最低。  相似文献

This article examines academic cooperation in the Baltic Sea Region. Academic networks are being discussed as indicators of regionalization, but research on the empirical basis is scarce. In the article, the regional networks of 70 higher education institutions in the Baltic States and the German federal state Mecklenburg–Western Pomerania are analyzed. The analysis shows a heterogeneous pattern for the regional higher education area. Regional embedding depends on the focus of an academy and its participation in regional networks. The article concludes with a discussion of options to be considered by regional organizations in order to strengthen regional academic cooperation.  相似文献

In this paper a Monte Carlo Markov Chain (MCMC) method for resolving DNA mixtures containing at most four peaks per locus into a major and a minor contributor is presented. Unlike previous methods, this method can provide posterior probability assessments of the most probable genotype and a likely range for the mixing proportion. The proposed method is applied to two DNA mixtures where the true genotypes of the contributors are known. The method provides posterior probabilities of the genotypes of the contributes which concord strongly with the known facts.  相似文献

A considerable amount of time and intellectual energy has been expended detailing the nature of the relationship between democracy and a state's use of repressive force against its citizens. This article moves the discussion forward both methodologically and substantively. I use a fully Bayesian structural model with latent variables to mitigate the effects of measurement error in both democracy and repression. Further, I estimate two models, one treating democracy as a single overarching concept, similar to the strategy followed by Davenport and Armstrong (2004), Poe and Tate (1994) and one treating democracy as two-dimensional (voice and veto) as suggested by Davenport (2007b). I find that the two models, though closely related offer substantively different predictions. Statistical measures of fit favor the two-dimensional model. Further, I find that the effects of voice and veto are each strongly conditioned by the other.  相似文献

Although acknowledging the importance of adolescent friendships in the etiology of delinquency, prior studies have yet to provide a detailed examination of the role of actual friendship networks in delinquency. Using data from the National Longitudinal Study of Adolescent Health (1995–1996), this study's incorporation of friendship networks allows for a more rigorous conceptualization and measurement of peer delinquency based on carefully defined networks of adolescent friendships. Findings illustrate that friendship networks are very heterogenous in terms of members' participation in delinquent behavior with the majority of adolescents belonging to networks containing both delinquent and non-delinquent friends. In support of differential association's premise that delinquent behavior is influenced by the ratio of definitions favorable to those unfavorable to law violation (Sutherland, 1947), the proportion of delinquent friends in a respondent's network is most strongly associated with respondents' subsequent delinquency. This relative measure of peer delinquency is preferable to a measure of the absolute level of delinquency occurring by friends, the average delinquency committed by friends, or the absolute number of delinquent friends. Enmeshment in a friendship network where consensus about the appropriateness of delinquency is maximized (i.e., all friends are delinquent or non-delinquent) most effectively constrains the behaviors of network members to resemble the groups' behavior.  相似文献

In this article the social networks and family ties of a pre-industrial (married and/or died between 1770 and 1850) and industrial (married and/or died between 1850 and 1950) cohort of deaf men and women are compared to each other and to a cohort of non-disabled siblings. The aim is to assess the extent to which the deaf participated in a full-fledged manner in family and social life and to evaluate the ways in which their social networks changed as a result of nineteenth-century industrialisation processes. The extent of social integration is deduced from the profile of the witnesses registered in marriage and death certificates. In the absence of personal testimonies of social experiences, demographic sources are invaluable for providing a glimpse of the everyday social life of ordinary people in the past. In combination with historical records identifying disabled individuals, this research is a first attempt to study the social opportunities of an up-until-now often forgotten, but nevertheless integral part of society: the disabled. Based on the analysis of the witnesses, this article argues that in the course of the nineteenth century deaf individuals became less embedded in their social environment and their relationship with their family weakened. The minority of married deaf persons, however, expressed a much higher connectedness with family.  相似文献

This article seeks to examine how public procurement policies for information and communication technology (ICT), aimed at improving the accessibility of ICT for persons with disabilities, have converged internationally. Convergence, in this instance, refers to the international harmonisation or acceptance of common standards and norms. Distinguishing itself from the predominant authorship in the area, this article seeks to explore convergence from a ‘bottom-up’ perspective, by examining the influence of networks of public and private actors on the design of public procurement standards for accessible ICT. Specifically, it will seek to answer how these actors and networks (varying in their level of coordination) have contributed to policy design in a unique area, public procurement of ICT goods and services. The influence of these networks will be discussed through the use of policy documents and semi-structured interviews, to provide empirical support for examining this ‘bottom-up’ analysis and distinguish it from the standard ‘top-down’ model usually employed in this field. This article also focuses on the role of policy actors in the United States and European Union that participated in the harmonisation of public procurement policy and the legal norms and instruments that give these policies their legal effect.  相似文献

This qualitative study explores how the estimated 1–3 million street children of Bangladesh cope with the verbal, physical, and sexual violence inflicted on them on an almost daily basis. Drawing on a sample of 75 street children ages 10–17 in the capital city of Dhaka, the study is based on multiple interviews with participants. Interview data and social network theory yielded insights about the types of violence endured and how age, gender, and location impacted risks faced by street children. The study also highlights the complex and varied roles that social networks and group solidarity, as well as the actions of individual peers, play in the survival of this vulnerable population.  相似文献

Many rural women in abusive partner relationships have reached to informal and formal support networks for assistance and have been negated, discounted, or treated in a nonsupportive manner. Women trying to end partner abuse rarely have found the help they seek from their communities; and family and friends may question, blame, or misunderstand women's situations. This study examined behaviors of supportive and nonsupportive persons and the effectiveness of support networks in helping rural women in abusive partner relationships become free from abuse. Supportive persons were found to help women access resources and extended informal and formal networks which in turn helped women become free from abuse. Nonsupportive persons hindered women's access to resources and facilitated in keeping women bound in abusive partner relationships. Partner abuse is a complex societal issue that involves a large network of support and services in order to help women become free from abuse, having implications to educators and service providers.  相似文献
