两种理论视野下的西欧穆斯林政治参与问题探析

20世纪60年代以来,穆斯林已经成为西欧社会不容忽视的现实存在,但是在政治参与方面,穆斯林远未能有效参与西欧各国的政治进程。穆斯林人口在种族、经济地位等方面的多样性是其有效参与政治的内在障碍。从资源动员理论和政治机会结构理论的分析可以发现,穆斯林对公民权、政治精英、参政渠道等政治资源的占有不足,加之欧洲殖民心理遗产的影响、欧洲的世俗化政策、伊斯兰恐惧症、外部穆斯林世界的影响等多种因素,共同构成了影响穆斯林广泛参与西欧政治生活的重要原因。

加入WTO后的南京人力资源开发与管理战略思考

加入ＷＴＯ以后,我们将面临一个更加对外开放的竞争环境,这种新环境将会对南京的人力资源存量和结构产生何种影响,我们将采取何种人力资源的开发和管理战略对策是南京经济保持可持续发展的重要内容之一。 南京的人力资源密集在中国是名列前茅的。国有经济企业和事业单位的专业技术人员有３０多万,其中高级专业技术人员的比重为 １０％以上;在宁高校的正副教授有近７０００余人,在校研究生有万余人［１］。 然而在我们对南京地区高新技术企业的实证分析显示,无论是三资企业、国有企业还是私营企业都认为阻碍企业技术创新的主要制约因…     

Sense of coherence and social support – Resources for subjective well-being and health of the aged in Finland

In this study we explored if the psychological and social resources of aged people (over 75 years) in Finland predict their subjective well-being and experienced state of health (n = 348). Data were taken from a larger Finnish survey on living conditions. Based on previous research on younger people we formed a model where morbidity, experienced quality of social support and sense of coherence together with economic resources are the predictors of both experienced state of health and subjective well-being. LISREL (8) path analysis was used to test the model. The model providing the most parsimonious explanation of the data suggested that a strong sense of coherence and high experienced quality of social relationships are strongly related to subjective well-being. Experienced state of health was associated with morbidity and subjective well-being, but there was no significant relationship between subjective well-being and morbidity.     

The quest for legitimacy and the communication of strategic cross-sectoral partnership on Facebook: A big data study

Nowadays, many wicked problems such as environmental issues require organizations from multiple sectors to form cross-sectoral alliances. Cross-sectoral alliance networks can transfer resources and signal affiliations and value alignment between strategic partners. The communication of cross-sectoral alliances is a form of CSR communication that serves organizations’ strategic goals and objectives. Drawing on the literature on digital CSR communication and legitimacy theory, this article examines which legitimacy needs shape the formation of cross-sectoral ties on Facebook in addressing environmental and sustainable development issues in the United States. Combining data-mining, text-mining, social network analysis, and exponential graph modeling, this research investigates the structure of a network among 3071 organizations across multiple sectors. Findings show that organizations’ cross-sectoral tie formation is mainly driven by social legitimacy and alliance legitimacy needs.     

基于高维波动率网络模型的股票市场风险特征研究

波动率是金融风险管理研究的重要内容之一。本文基于复杂网络理论和数据挖掘技术提出股票市场的高维波动率网络模型。首先运用互信息度量不同股票价格波动之间的相关关系,其次对股票市场不同周期下的波动情况建立度的中心势、平均距离、幂律分布等网络拓扑指标,再次根据这些指标利用Prim算法构建出高维波动率网络模型,最后运用Newman-Girvan算法对股票价格波动率的相关性进行分层研究。高维波动率网络模型突破了传统波动率模型关于变量维数的限制,能够在依赖少量假设的基础上,挖掘出多个金融市场主体间的相互关系,反映金融市场的风险特征及网络拓扑性质。实证结果发现：与常用的Pearson相关系数法相比,在互信息框架下,股价波动的非线性相关关系得到了更好的度量;股票市场的整体波动性与个股波动率相关性变化趋势相反,市场处在高波动时期资产组合分散化效果较好;网络中存在少量度数大的关键节点和中心节点,风险通过这些节点可以迅速传递到整个市场;股票市场的运行具有明显的行业聚集现象;网络分层研究进一步直观的展现了风险在层与层之间的传递规律和与之对应的行业特征。高维波动率网络模型为挖掘股票市场的风险特征与管理金融风险提供了一个新的工具。     

German fathers and their preferences for shorter working hours for family reasons

This study is among the first to analyze fathers’ preference for shorter working hours specifying that the preference is related to the wish to spend more time with the family. Assuming that preferences are context-dependent, this article explores the relevance of the family and workplace context for preference formation. We develop need-based and capability-based arguments to contrast the job demands–resources approach and the capabilities approach in work–family research. Using a sample of 632 fathers from the German LEEP-B3 data with a representative linked employer–employee design for large work organizations we conclude that fathers’ preferences for shorter working hours are indeed context-dependent and that there is more evidence for need-based arguments than opportunity based arguments. Our results indicate that fathers with young children and fathers with high work demands are more likely to desire shorter working hours, whereas a reduction in working hours appears to be unnecessary for fathers who can satisfactorily reconcile work and family life through support from their supervisors. In contrast to capability-based arguments the perception of a highly demanding work culture was not found to decrease but increase the likelihood to desire to work shorter hours.
