集群剩余与企业集群内部协调机制

企业集群内部协调既不同于市场上价格机制的无形之手,又不同于企业内部行政命令的有形之手。本文分析指出,集群内部协调的目标在于追求集群剩余,并根据企业行为的规律性对集群剩余进行了分析;介绍集群内部的各种协调机制,在此基础上,分析协调机制与集群剩余实现之间的关联。     

产业集群中跨国子公司战略地位与母子关系的演进

本文首先基于理论分析,指出优势产业集群中的跨国子公司完全有可能成为跨国公司竞争优势的来源。由此,文章分析了集群中跨国子公司存在的四类知识流以及影响四类知识流方向和流量大小的三种重要影响因素,并根据后两个因素区分了集群中子公司在跨国公司内部战略地位上的差异。基于战略与结构的孪生性,本文论述了集群中跨国公司母子关系的变迁,分析了集群中子公司的双重根植性。     

浅析司法实践中的“漏斗效应”

犯罪问题,古今中外普遍存在,是一个产生原因错综复杂、表现形式变化多样的重大社会问题,而在追究犯罪人刑事责任方面也出现了"破案多、捕判少"的漏斗现象.如何正确分析理解"漏斗效应"是当前期待解决的一个重要课题.     

论伍廷芳的司法独立思想

伍廷芳的司法独立思想建构在西方"三权分立"原则之上,其主要内容有三点:一是反对行政权干涉司法权;二是采用西方律师制、陪审制、公开审判、辩论式诉讼、无罪推定等西方资产阶级文明审判方式和原则;三是开办法律学堂,实行法官高薪制。伍廷芳的司法独立思想是中国近代法制思想的重要组成部分。     

OPTIMAL EXPERIMENTAL DESIGNS FOR MULTILEVEL MODELS WITH COVARIATES

In this paper optimal experimental designs for multilevel models with covariates and two levels of nesting are considered. Multilevel models are used to describe the relationship between an outcome variable and a treatment condition and covariate. It is assumed that the outcome variable is measured on a continuous scale. As optimality criteria D-optimality, and L-optimality are chosen. It is shown that pre-stratification on the covariate leads to a more efficient design and that the person level is the optimal level of randomization. Furthermore, optimal sample sizes are given and it is shown that these do not depend on the optimality criterion when randomization is done at the group level.     

中国各地区经济发展水平的实证分析

利用1995-2006年数据,采用时序多指标综合评价法,对中国各地区经济发展水平进行评价研究。结论表明：虽然中国1995-2006年经济增长迅速,但是经济发展水平并未得到显著提高;各地区经济发展不均衡,地域差距较大且有逐年扩大的倾向。     

论审判独立的公正与效率价值

应进一步加大审判独立的程度.审判独立是实现审判公正和效率价值的手段.一方面,它对诉讼法程序公正的诸项标准具有保障作用;另一方面,它又是缩减诉讼成本、优化资源配置的重要途径.而当下我国审判不独立是相当严重的,它导致审判公正和效率的双重弱化.     

迅速审判:不同刑事诉讼模式下的理念与制度比较

从刑事诉讼制度的历史发展角度看,迅速审判的理念始终存在。对不同诉讼模式下的迅速审判的理念与制度进行分析,可以根据价值目标的不同将迅速审判的理念与制度划分为纠纷解决型、权力行使型和权利保障型,根据效力范围的不同可划分为局部推进型和整体推进型。迅速审判的类型演进呈现一种进化发展的基本态势,理想的类型搭配是:权利保障型、权力实施型的混合型加整体推进型。可以由此来确定未来一定时期内我国刑事程序改革的基本思路。     

嵌入GVC的我国产业集群竞争力提升模式研究——基于“双钻石模型”

全球化生产网络的形成,片断化生产模式的发展,使得传统的产业集群在构建其区域经济系统时必须嵌入到全球的价值链(GVC)中,构建产业集群的全球竞争力提升模式。本文主要在波特钻石模型的基础上构建适合我国产业集群竞争力提升的双钻石模型,并且分析在GVC下国内钻石的变化趋势。在此基础上从双钻石模型的四个要素出发提出我国产业集群竞争力提升的路径选择。     

Statistical methodology for assessing homology of intronic regions of genes

We consider the problem of statistically evaluating the similarity of DNA intronic regions of genes. Present algorithms are based on matching a sequence of interest with known DNA sequences in a gene bank and are designed primarily to assess homology among exonic regions of genes. Most research focuses on exonic regions because they have a clear biological significance, coding for proteins, and therefore tend to be more conserved in evolution than intronic regions. To investigate whether the intronic features of genes whose expression is highly sensitive to environmental perturbations differ from genes that have a more constant expression, a collection of oncogenes, tumor suppressor genes, and nonregulatory genes involved in energy metabolism are compared. An analysis of the features of these genes' intronic regions result in clustering by regulatory group. In addition, Billingsley's test for Markov structure (1961) suggests that 67% of the intronic regions in this collection of genes show evidence of nonrandom structure, indicating the possibility of a biological function for these regions. The result of Billingsley's test for homology is used as input to a clustering algorithm. The biological significance of this methodology lies in the identification of groups based on the intronic regions from genes of unknown function. With the advent of rapid sequencing techniques, there is a great need for statistical techniques to help identify the purpose of poorly understood portions of genes. These methods can be utilized to assess the functional group to which such a gene might possibly belong.
