Über Macht und Ehre in Vereinen und Verbänden: Ein Rückblick auf Forschung und Politik

Cultural and professional associations are the expression of the modern society with structured organisations. The 19th century was the marking epoch of the constitution of associations in Germany. The involvement of associations in the political live, specially the professional ones, is typical in Germany. While political sciences focus on the analyses of interest representation and mediation functions of organisations, sociology research covers the full range of social, psychological, political and economical functions of organisations. Management and especially human resource management topics are presently gaining a growing importance within the research community which focuses on the cultural and professional organisations.     

指数分析中多种方法的结合运用

指数分析法在经济分析的各个领域里已得到广泛的应用。但只用单一方法分析问题往往不够全面、深入。本文以工业劳动生产率的分析为例,从三个方面,多角度、多层次、比较系统地阐述了指数分析中独具特色的分析手法。

Sets of alternatives as Condorcet winners

We characterize sets of alternatives which are Condorcet winners according to preferences over sets of alternatives, in terms of properties defined on preferences over alternatives. We state our results under certain preference extension axioms which, at any preference profile over alternatives, give the list of admissible preference profiles over sets of alternatives. It turns out to be that requiring from a set to be a Condorcet winner at every admissible preference profile is too demanding, even when the set of admissible preference profiles is fairly narrow. However, weakening this requirement to being a Condorcet winner at some admissible preference profile opens the door to more permissive results and we characterize these sets by using various versions of an undomination condition. Although our main results are given for a world where any two sets – whether they are of the same cardinality or not – can be compared, the case for sets of equal cardinality is also considered.

青少年疏离感的特点及其与家庭功能的关系

通过对875名初一至高二学生的问卷调查,探讨了青少年疏离感发展的特点及其与家庭功能的关系。结果发现：（1）青少年的环境疏离感最高,其次是社会疏离感,人际疏离感最低。（2）高中生疏离感显著高于初中生,在每一年龄段内,疏离感随年级升高而增强;但青少年疏离感性别差异不显著。（3）家庭功能中的角色、沟通、情感反应和情感介入可以显著正向预测青少年的疏离感,问题解决和行为控制对青少年疏离感的预测不显著。     

成岩作用及阶段对碎屑岩储层孔隙演化的控制

碎屑岩储层孔隙演化受有机-无机成岩作用的影响，在埋藏成岩阶段，有机质成熟过程中脱羧作用产生的有机酸对碎屑岩中的方解石、长石等溶蚀所形成的次生扎隙，是深部储层中高孔渗段发育的重要原因，随埋深增加，成岩阶段由早-晚发展，有机质由未成熟-成熟演化，在此期间，储层孔隙经历了消亡与新生的发展过程。在同一盆地中，不同层位储层经历的最大埋深如果相近，所处成岩阶段也相近，其孔隙演化史亦趋于相似;反之，同一层位的储层所处的最大埋深不同，成岩阶段不同，其孔隙特征也就不同。     

情感、自然、自我——论卢梭的浪漫文风

在文学领域,卢梭的浪漫主义风格主要体现在三个方面:讴欧真挚的情感、崇尚质朴的自然、强调个性的解放.情感、自然、自我构成三位一体,形成了卢梭的浪漫主义风格,并贯穿于他的主要文学作品中.
