How does education have an impact on ethnocentrism? A structural equation analysis of cognitive,occupational status and network mechanisms

Previous studies have distinguished cognitive, occupational status and network mechanisms in the relation between education and ethnocentrism. Hypotheses on these mediating mechanisms are derived from socialization theory, realistic group threat and contact theory. In the current study we use structural equation modeling to investigate the explanatory power of these three mechanisms simultaneously. The analysis is based on a representative population survey from the Netherlands (NELLS 2009, n = 1910). The results show that more than half of the initial association between education and ethnocentrism can be attributed to cognitive ability and occupational status mechanisms. The remaining part of the overall association, however, still has to be modeled as a direct relationship between education and ethnocentrism. This direct association can be attributed either to social desirability or to a direct liberalizing effect of education on social and political attitudes. Our analysis tentatively suggests that the rise of average education levels in Western societies might lead to less ethnocentric attitudes via the cognitive sophistication mechanism.

国家体育总局体育社会科学、软科学课题选题实证分析

以2003-2008年国家体育总局体育社会科学、软科学研究项目共立项课题为数据源,运用资料分析法、数理统计法、逻辑分析法,分析我国体育社会科学研究的动向。统计结果表明:国家体育总局体育社会科学重点研究基地是我国体育社会科学高水平研究成果的主要产区,我国的体育社会科学研究从整体上来讲,以研究国内和省内为主,而对国外研究或中外对比研究则相对较少,基础研究、应用研究、开发性研究比例分别为为3∶18∶1,研究热点集中在竞技体育、体育管理、奥林匹克、体育产业、体育法、而关注较少的偏门选题是:体育社团、体育方法、学科理论。加强基础研究、促进跨学科研究、正确引导热点研究、避免低水平重复、促进体育社会科学理论原始创新是我国体育社会科学研究努力地方向。

Ongoing child welfare services: Understanding the relationship of worker and organizational characteristics to service provision

Ongoing child welfare services are put in place after completion of the initial maltreatment investigation when there is a perceived need to mitigate the risk of future harm. The knowledge of how clinical, worker, and organizational characteristics interact with this decision to provide ongoing child welfare services is not well integrated in the research literature. Using secondary data from the Canadian Incidence Study of Reported Child Abuse and Neglect-2008, this study’s primary objective is to understand the relationship of clinical, worker, and organizational characteristics to the decision to transfer a case to ongoing child welfare services and their relative contribution to the transfer decision in Canada. Findings indicate that several clinical level variables are associated with families receiving ongoing services. Additionally, organizational factors, such as type of services offered by the organization and the number of employee support programs available to workers, significantly predicted the decision to transfer a case to ongoing services. While no worker factors, such as education, amount of training, experience, or caseload, were associated with ongoing service receipt, the intraclass correlation coefficient of the final three-level parsimonious model indicated substantial clustering at the worker level. Results indicate that Canadian child welfare workers make decisions differently based on factors not available in the current study and that what would be deemed as important worker characteristics do not necessarily predict this outcome. Findings and implications for future research are discussed.
