控股股东现金流权、控制权与企业资本配置决策研究

基于企业内部资本配置的理论阐释,以无风险资产和风险性资产的组合投资为研究对象,从控股股东无偿占用上市公司内部资金的角度构建企业价值期权模型,探析控股股东的现金流权、现金流权与控制权分离度对资本配置决策和企业价值的影响。研究结果表明,控股股东的现金流权与企业资本配置效率正相关,与企业价值正相关;现金流权与控制权分离度与企业资本的配置效率负相关,也与企业价值负相关;并且发现,由大股东侵占而产生的对风险性资产的非效率"挤占"是导致上市企业资本配置行为扭曲的一个重要动因。     

基于Petri-Net的钢铁企业生态工业园仿真研究

钢铁行业是实现循环经济目标的重要环节。在对钢铁企业现有废弃物处理模式分析（以宝钢集团为例）的基础上,阐述了生态工业园模式的必要性。结合包钢生态园模式和相关研究,抽象出钢铁生态工业园物流简化模型。在此基础上,以该简化模型中的主要固体废弃物的处置为研究对象,应用Petri—Net就钢铁工业生态工业园模式进行仿真研究。仿真结果证明,生态园模式具有显著的经济、社会和环境效益,是实现循环经济的重要途径。     

儿童画里的生命概念：基于5-6岁儿童生命主题绘画的探析

儿童所掌握的生命概念,涉及他们对生命本质特征的基本认知,属于一种朴素的生物理论。到5-6岁时,儿童的生命概念已有所发展,在一定的教育支持下能够趋向成熟。为分析儿童潜在的生命概念,本研究对32幅以“生命”为主题的绘画作品进行编码分析,结合儿童访谈,探究蕴含在儿童主题画中的生命认知与理解、情绪体验和基于已有观念表现出的生命行为。研究发现：在生命认知方面,5-6岁的儿童不能完全区分生命体与非生命体,并从生物学特征和形而上的特征来认知死亡;在生命情感方面,儿童表现出兼具模糊性、哲理性、积极性和消极性的特点;在生命行为方面,儿童画中高频出现关注自我的行为表现,其绘画表达存在明显的性别差异。据此,提出正视儿童生命概念认知中的“类比思维”;从哲学层面理解儿童生命主题绘画中蕴含的生命价值;丰富儿童死亡教育内容体系的建议。     

Retracted: The Development of Willingness to Sacrifice and Unmitigated Communion in Intimate Partnerships

The above article, published online on December 27, 2017 in Wiley Online Library ( wileyonlinelibrary.com ) has been retracted by agreement between the author, journal Editor in Chief Kristi Williams and Wiley Periodicals, Inc. The retraction has been agreed due to discovery of a coding error by the author. The labeling for the willingness to sacrifice and unmitigated communion items was mistakenly reversed during the construction of the longitudinal dataset. The authors notified the editor immediately upon discovering the error. Although the central conclusions of the research are unchanged, a fully corrected version of the paper is forthcoming.     

„Politische Religionen“ (Eric Voegelin und Raymond Aron) — ein Begriff zur Differenzierung von Fundamentalismen?

The concept of ?political religion“ has been introduced in the late 1930s by Eric Voegelin and Raymond Aron in order to analyze the ?religious character“ of the new totalitarian political mass movements, i. e. Fascism, National Socialism and Communism, as ?collective religions of salvation“ from a critical perspective. Both abandoned the term later and replaced it by ?modern political gnosis“ or ?ersatz of religion“ (Voegelin) and ?secular religion“ (Aron). In this paper the concept and history of the term ?political religions“will be reconstructed, and the author examines the question, if it can be considered an appropriate tool of differentiation in the discussion of socalled fundamentalisms. This will be accomplished by using the example of ?radical Islamism“.     

Using fractionalization indexes: deriving methodological principles for growth studies from time series evidence

Recent cross-country growth studies have found that ethnolinguistic fractionalization is an important explanatory variable of long-run growth performance. This paper highlights some limitations of cross-country studies by focusing on the time series evidence for South Africa. In presenting variation over time in a number of social dimensions, this paper adds longitudinal evidence on a range of dimensions that have been linked to long run economic development. Given South Africa’s history of ethnic and racial politics, it constitutes a useful case study to explore the dynamics of the possible effects of ethnolinguistic fractionalization on growth. We introduce several new sets of fractionalization indicators for South Africa: ethnolinguistic, religious and cultural fractionalization, and a polarization measure. The results of this study provide important nuance to the existing body of evidence, for the use of fractionalization indices in growth studies.

Strong law of large numbers for generalized sample relative entropy of non homogeneous Markov chains

In this paper, we study the strong law of large numbers for the generalized sample relative entropy of non homogeneous Markov chains taking values from a finite state space. First, we introduce the definitions of generalized sample relative entropy and generalized sample relative entropy rate. Then, using a strong limit theorem for the delayed sums of the functions of two variables and a strong law of large numbers for non homogeneous Markov chains, we obtain the strong law of large numbers for the generalized sample relative entropy of non homogeneous Markov chains. As corollaries, we obtain some important results.
