大学生抱怨情绪解码

大学生抱怨情绪作为弥漫在大学生中的一种消极情绪和精神状态,其产生主要是由于＂90后＂大学生独特的成长压力、人际交往及恋爱中的情感困惑、大学教育管理价值取向的异化、现实社会失范现象的心理冲击而导致的,有效疏导大学生抱怨情绪可以从引导大学生合理地宣泄抱怨情绪、建立大学生心理援救长效机制、发挥思想政治教育的价值引导作用、解决好大学生就业和生活等实际困难、利用社会实践提高大学生适应能力这几个方面着手。     

Improved estimator of population total in PPS sampling

In this paper, we have considered an estimation of the population total Y of the study variable y, making use of information on an auxiliary variable x. A class of estimators for the population total Y using transformation on both the variables study as well as auxiliary has been suggested based on the probability proportional to size with replacement (PPSWR). In addition to many the usual PPS estimator, Reddy and Rao's (1977) estimator and Srivenkataramana and Tracy's (1979, 1984, 1986) estimators are shown to be members of the proposed class of estimators. The variance of the proposed class of estimators has been obtained. In particular, the properties of 75 estimators based on different known population parameters of the study as well as auxiliary variables have been derived from the proposed class of estimators. In support of the present study, numerical illustrations are given.     

On the correspondence between frequentist and Bayesian tests

Modern theory for statistical hypothesis testing can broadly be classified as Bayesian or frequentist. Unfortunately, one can reach divergent conclusions if Bayesian and frequentist approaches are applied in parallel to analyze the same data set. This is a serious impasse since there is a lack of consensus on when to use one approach in detriment of the other. However, this conflict can be resolved. The present paper shows the existence of a perfect equivalence between Bayesian and frequentist methods for testing. Hence, Bayesian and frequentist decision rules can always be calibrated, in both directions, in order to present concordant results.

The international scale and scope of European multinationals

This study analyzes the international scale and scope of European multinational enterprises (MNEs). By using five widely used multinationality measures and the corresponding five measures for intra-regional activities, the results confirm that the European MNEs focus on their home region market rather than the global market. No evidence exists that European MNEs focus on global markets or were becoming geographically diversified during 2000–2006. Additionally, this study suggests that scale and entropy measures, which are based on sales and assets, are better than scope measures, which are based on country counts. Simple country and subsidiary counts wrongly guide researchers to conclude that the MNEs are more dispersed than they really are.     

环境治理的风险社会学分析

从风险社会学角度分析,环境治理出现难题的重要因素是地方政府、社会公众与科技专家之间的环境风险认知差异。差异的产生原因有客观因素也有主观因素。要矫正环境风险认知差异需要科学客观的环境风险测量,但环境风险测量不等于公众对环境风险的可接受性。要真正实现环境风险的社会可接受性,还有待于加强多主体间的环境风险沟通。在环境风险沟通中尤其应当提升公众参与对环境治理的积极效用,形成广泛而有益的环境风险共识,以促进政府与公众、科技与社会之间的良性互动。     

中国就业管制的测量

对就业管制程度进行判断是就业保护法经济学研究的基础。就业管制测量方法可以分为客观测量和主观测量两种类型。由于测量方法的不完善和测量实施过程的不同,不同的测量方法得出的结果会出现较大差异。采用OECD的就业保护立法指数对我国改革开放30年来就业管制情况进行的阶段性测量结果与我国劳动力市场的发展状况相符合。这种测量方法在我国有一定的适应性,但也存在一些缺憾。因此,亟须对我国的就业管制做进一步的主观调查研究,创建中国劳动力市场管制指标体系,以全面反映我国的就业保护水平。     

关于完善我省养老保险制度的几点思考

养老保险作为社会保障的重要组成部分,在实施当中政策是否正确、措施是否得当、制度是否完善,不仅对养老保险制度的全面推进产生至关重要的影响,而且也会对经济建设、社会和谐发展带来巨大的作用或反作用。文章在分析我省现行养老保险制度存在的问题基础上,提出了完善这一制度的一些对策。     

动产用益质权法律关系分析

动产用益质权包含动产质权和动产用益债权两种不同性质的权利,是动产质押法律关系与动产用益债权法律关系竞合的产物。动产用益质权的设立弥补了质物不能用益的缺憾。动产用益质权法律关系,也可以同时是占有媒介关系的竞合。用益质权人占有的本权有两个,一是质押债权,一是用益债权。两种法律关系虽然竞合,但作为法律关系标的的给付并不相同,对孳息收取的效力也就不同。单纯的质权人只能收取天然孳息,应与法定孳息绝缘。
