拥挤理论在超市结算区人群管理中的应用

通过确定超市结算区人体平均投影面积,给出了结算区最大容许人数。利用拥挤理论,根据不同时段下的人群到达率,得出了收款台最低开放台数,并据此对结算区内人群聚集风险进行了分析。在综合考虑结算区的最大容许人数、人群可忍受的平均等候时间及机器利用率的基础上,确定了各时段的收款台最佳开放数。从超市的自身效益、购物环境和聚集人群安全性出发,针对超市结算区的人群聚集风险提出了可行的减缓措施。     

二层次四要件犯罪构成论——兼议正当化行为的体系地位

以解决正当化行为在犯罪论体系中地位不定,及其与犯罪构成关系不明为突破口;以反映定罪过程、权力与权利的平衡以及对抗制的诉讼程序特点为价值立场;兼顾中国已有的理论与实务情况,主张在我国犯罪构成论的应有结构为两层次四要件犯罪构成结构.此即:第一层次,三个要件,依次为犯罪客观要件、犯罪主体要件和犯罪主观要件;第二层次为犯罪客体一个要件,其中,正当化行为等作为排除犯罪客体的事由在此纳入犯罪构成要件之中.无此事由,犯罪即告成立.     

IDENTIFYING THE PSYCHOLOGICAL FACTORS THAT MEDIATE THE ASSOCIATION BETWEEN PARENTING PRACTICES AND DELINQUENCY*

Past research has largely ignored the developmental changes within the child that account for the association between parenting and risk for delinquency. We used structural equation modeling and data from a longitudinal study of several hundred African‐American families to test the contentions of various theories regarding the sociocognitive and emotional factors that mediate the impact of parental behavior on a youth's risk for delinquency. Our findings largely supported the theories. The impact of monitoring/discipline was indirect through low self‐control and acceptance of deviant norms, whereas the effect of hostility/ rejection was indirect through low self‐control, hostile view of relationships, and acceptance of deviant norms. These two dimensions of parenting were no longer related either to affiliation with deviant peers or to conduct problems once the effects of these psychological characteristics were taken into account; the impact of these parenting practices was completely mediated by these four cognitive/affective variables. Contrary to expectation, however, these psychological factors did not mediate any of the relationship between caretaker involvement in antisocial behavior and child conduct problems.

从控制论视阈看文化在社会发展中的作用

作为特殊意识形态的自然科学技术,无论从社会演进的宏观动力机制看,还是从其微观动力机制看,都对社会发展具有决定性作用。社会意识形态虽然在宏观动力机制上处于从属的地位,但从微观动力机制上考察,对历史进程发展的迟速则具有决定性意义。     

The European airline industry: law and economics of low cost carriers

This article offers an analysis of the European airline industry in order to understand the new dynamics of the competitive field. The liberalization process did not lead the entrance of competitors similar to incumbents, but a new organizational model has been developed, the one of low cost carriers. The incumbents’ reaction to the liberalization process coupled with the entrance of low cost companies into the sector are hence considered. Two theories are analysed: the contestable markets theory, to understand the theoretical vision that has influenced the liberalization process, and the core theory, a modern approach to the concept of destructive competition that, according to some authors, is a recurring problem in the sector. While numerous barriers to entry still exist, the paper examines how the organizational model of low cost companies has helped new entrants to overtake these obstacles. By the same token, the application of the core theory does not seem to justify strategic alliances taking place in these years. The competitive framework is definitely clearer if we analyse sector changes in a different way, from the point of view of low cost companies considered as new market actors.     

宪法理解与宪政的建立和巩固——一种宪政经济学的视角

宪法之维系和宪政之建立与巩固,有赖于对宪法的复合式理解。宪法的内容构成、属性、层次以及宪政之建立与巩固过程,都是多元化的。宪政经济学视野下的契约宪法观、协作装置宪法观、惯例宪法观与自发生成的制度宪法观都把宪法简单化与单一化。要建立和巩固一个宪政体制,宪法的制定必须与某一共同体的惯例保持一致,同时,宪法必须具备稳定性、有效性、效率性。     

治理理论的兴起与行政法的变迁

行政法是关于行政的法,公共行政的改革与发展必然对行政法产生影响,为行政法学提供新的研究课题。20世纪下半叶,治理理论的兴起,受到世界各国的广泛关注,行政主体的多元化和行政行为的非强制性被认为是治理理论两个明显的特征。以传统统治理论为基础形成的行政法不能解释行政主体的多元化和行政行为的非强制性现象,在治理理论的背景下,行政法面临着发展变迁的挑战。     

我国警检关系之协调模式探析

目前警检双方常常在刑事诉讼中发生冲突,以致有时不能准确高效地完成刑事诉讼的根本任务。为走出警检冲突的困境,有人提出检察引导侦查这一新型警检关系模式。
