Organizational ecology of immigrant employment and organizational buffer zones: Who leaves first when the organization gets into trouble?

Using data from the German social insurance system immigrant employment in organizational buffer zones will be investigated from an organizational ecology perspective. Theories in organization and labor market research predict higher exit rates of employees holding jobs in buffer zones. These buffer zones protect organizations from unfavorable environmental turbulences. Consequently, analyzing the impact of buffer zone employment on job stability of immigrants requires a fully dynamic approach, which goes beyond a mere identification of generally increased turnover rates of immigrants.In the first step, determinants of organizational dissolution rates will be estimated. In order to obtain a dynamic measurement of unfavorable environmental conditions, the model includes both organizational and time-varying environmental characteristics of organizational populations. This will be done by using a three-level mixed-effects hazard model controlling for observed and unobserved environmental characteristics. In the second step, dissolution rates predicted in the first step will be used as an explanatory variable. These rates indicate the degree of enactment of the flexible buffer zone. It will be shown that immigrants have indeed higher turnover rates, but they tend to remain longer in their organizations when environmental conditions deteriorate—and they are not those who leave first when the organization gets into trouble.     

行刑一体化与刑罚执行权的新配置

尽管行刑是刑罚运用过程的最后环节,但是,行刑效果如何则直接关系到刑罚目的能否最终实现。科学合理地配置刑罚执行权将有助于行刑效率的提高与刑罚运行机制的完备。通过对当代中国刑罚执行权的现实考察,不难发现,中国现行刑罚执行权配置并不科学合理,存在着行刑权过于分散、相互之间彼此抵牾之处,这严重地影响了刑罚功能的发挥。因此,树立行刑一体化的理念,科学地配置刑罚执行权,乃是中国刑法理论界与实务界共同努力的方向和目标。     

A computationally simple bivariate survival estimator for efficacy and safety

Both treatment efficacy and safety are typically the primary endpoints in Phase II, and even in some Phase III, clinical trials. Efficacy is frequently measured by time to response, death, or some other milestone event and thus is a continuous, possibly censored, outcome. Safety, however, is frequently measured on a discrete scale; in Eastern Cooperative Oncology Group clinical trial E2290, it was measured as the number of weekly rounds of chemotherapy that were tolerable to colorectal cancer patients. For the joint analysis of efficacy and safety, we propose a non-parametric, computationally simple estimator for the bivariate survival function when one time-to-event is continuous, one is discrete, and both are subject to right-censoring. The bivariate censoring times may depend on each other, but they are assumed to be independent of both event times. We derive a closed-form covariance estimator for the survivor function which allows for inference to be based on any of several possible statistics of interest. In addition, we derive its covariance with respect to calendar time of analysis, allowing for its use in sequential studies.     

Does Society Matter? Life Satisfaction in the Enlarged Europe

Life satisfaction is quite heterogeneously distributed across countries of the enlarged European Union. Previous research has shown how living conditions within individual countries, such as access to material and emotional resources, are important for personal well-being, but it has been less successful in explaining differences between countries. This article investigates whether it matters in which political and economic circumstances people live, as well as whether their particular perception of the quality of their societal environment plays a role. People are well aware that the institutional and cultural settings in which their lives are embedded create opportunities and limitations: within individual countries, perceptions of society influence life satisfaction outcomes irrespective of access to resources. However, their importance for well-being differs across Europe: perceptions of societies are highly decisive in countries that provide only a minimum of social security and in which the reliability of political institutions is poor. In rich and stable countries, the impact is weaker and private social support becomes more important. In addition to these country-specific weights of life satisfaction determinants, life satisfaction variations between countries can be explained to a large extent by taking into consideration the economic performance, the social security level, and the political culture in a country—all in all, general conditions that enable people to live a respectable life.     

出生人口性别比与和谐社会建设:一个定性和定量分析

20世纪80年代中期以来,中国的出生性别比持续攀升,出生人口性别结构严重失衡。运用定性和定量相结合的研究方法,探讨出生性别比失衡的潜在因素和制度因素。分析结果表明,农村地区出生性别比的失衡与儿子预期的经济价值和文化功用相关。最后提出具有针对性的缓解出生性别比失衡的建议。     

劳动力市场分割对农村流动劳动力收入水平的影响——来自甘肃省十个样本村的调查与争析

近年来,劳动力外出务工已成为农民增收的一个重要途径。农村流动劳动力作为一个特殊群体,影响其收入的因素既具有居民收入的一般规律。又具有其特殊性。现有的研究一般以传统人力资本理论和收入均等化理论等为基础,来分析农村流动劳动力收入水平的影响因素。本文以甘肃省农村流动劳动力的调查数据为样本,试图从流动劳动力的人口学特征、就职行业、流动去向及工作稳定性等四个方面分析劳动力市场分割对农民工收入水平的影响。     

基于二阶段嵌套锡尔系数的人口分布的差异研究

文章首先提出了人口分布锡尔系数的概念及其一阶、二阶分解方法,接着以江苏省为研究区域,基于三大地带（苏南、苏中和苏北）、13个地级市、106个县（县级市、市辖区）三级结构的地域行政单元,分别运用一次、二次分解对全省的人口分布的区域差异进行细分测度．将江苏省人口分布的差异性分解为苏南、苏中、苏北三大地带闯的差异、三大地带内地级市之间的差异以及各地级市的内部差异三部分。其主要结论为：以地级市为计算单元的一阶段分解结果显示．苏南、苏中和苏北三个地带间人口分布的差异性是造成一阶段分解的全省人口分布差异的主要原因;以县级行政单元的二阶段分解结果表明．地级市内部的差异是江苏省人口分布的整体差异的主要构成部分;通过运用局部G统计量对各县级单元人口分布的热点探测发现,“热点”地区的人口分布差异性大．“冷点”地区的差异性小．
