Gender differences in willingness to compete: The role of public observability

A recent literature emphasizes that gender differences in the labor market may in part be driven by a gender gap in willingness to compete. However, whereas experiments in this literature typically investigate willingness to compete in private environments, real world competitions often have a more public nature, which introduces potential social image concerns. If such image concerns are important, and men and women differ in the degree to which they want to be seen as competitive, making tournament entry decisions publicly observable may further exacerbate the gender gap. We test this prediction using a laboratory experiment (N = 784) that varies the degree to which the decision to compete, and its outcome, is publicly observable. We find that public observability does not alter the magnitude of the gender gap in willingness to compete in an economically or statistically significant way.     

FDI的工资效应研究——基于江苏省制造业面板数据的分析

利用江苏省制造业2000--2006年的面板数据，从行业角度分析FDI对于江苏省制造业平均工资以及国有企业工资的影响，结果表明外资企业的进入可以通过提高整体的劳动生产率水平从而间接提高整体平均工资水平；劳动力工资与加工贸易的开放程度之间呈正相关关系，而与行业规模大小呈负相关．外资对于国有企业劳动力工资存在正的工资溢出，但是国内资本对于劳动力工资水平的影响与外商直接投资相比相差不大，甚至可以超过外商直接投资的贡献。     

南京国民政府时期南洋侨教政策负面影响述评

由于历史和现实的缘故，国民政府十分关注海外华侨尤其南洋华侨的教育，形成了比较完善的华侨教育体系，学校和学生数量呈上升趋势，学生素质也不断提高。然而由于国民政府侨教政策自身固有的弊病，给南洋侨教带来了相当的消极作用，限制了南洋侨教事业的进一步发展。     

葬礼:面对死亡的社会安排 ———城市环境下葬礼仪式浅析

通过实地观察和对殡仪馆工作人员的访谈，描绘了天津市城市内部现有的国家规范框架下葬礼仪式的具体过程以及附着在这个框架下的民间习俗的现状，试图通过对国家规范框架下的“正式”葬礼仪式及与其相对的“非正式”仪式——家庭告别仪式的程序形式的简略描述，展现在城市中普通个人的葬礼基于公共环境和家庭环境不同场景所采用的不同仪式过程。这是民间习俗对规范仪式的补充，同时也是“正式”规范对这种“非正式”实践的通融和消化。在描述现状之外，作者试图讨论蕴含在葬礼仪式中，不同死亡个体的葬礼仪式形式、规模及参与者等方面的区分所展现出的一种社会对死亡个体生前所处社会结构地位的认同，这种认同不仅反映了仪式所处社会背景的秩序和结构，也强化了这个社会的秩序和价值判断标准。     

Doing Gender unto the Other: Fiction as a Mode of Studying Gender Discrimination in Organizations

Although ‘doing gender’ has been recently defined as an accomplishment, an element of social practice, this understanding of the concept needs to be extended to coercive action such as subtle workplace discrimination. Even though great effort has been invested in revealing the dynamic of such social practices, the researcher's task is not easy for a variety of reasons. This type of study is difficult to conduct by following traditional research design and many alternative approaches have been tried. This article presents the possibility of using fiction as one possible and relatively unexploited venue of research.     

Test for homogeneity in Hardy–Weinberg normal mixture model

The phenotype of a quantitative trait locus (QTL) is often modeled by a finite mixture of normal distributions. If the QTL effect depends on the number of copies of a specific allele one carries, then the mixture model has three components. In this case, the mixing proportions have a binomial structure according to the Hardy–Weinberg equilibrium. In the search for QTL, a significance test of homogeneity against the Hardy–Weinberg normal mixture model alternative is an important first step. The LOD score method, a likelihood ratio test used in genetics, is a favored choice. However, there is not yet a general theory for the limiting distribution of the likelihood ratio statistic in the presence of unknown variance. This paper derives the limiting distribution of the likelihood ratio statistic, which can be described by the supremum of a quadratic form of a Gaussian process. Further, the result implies that the distribution of the modified likelihood ratio statistic is well approximated by a chi-squared distribution. Simulation results show that the approximation has satisfactory precision for the cases considered. We also give a real-data example.     

郑玄《尚书》训诂的谶纬化

郑玄是汉学的总结性人物,其《尚书》训诂,是东汉《尚书》学之代表。郑玄《尚书》训诂,融古文、今文、谶纬于一体,是两汉《尚书》学谶纬化范围扩大的最好例证。通过郑玄,我们可以知道,古今文《尚书》学的对立并不妨碍双方对谶纬的吸收,谶纬在郑玄手中变成整合古今文《尚书》学的桥梁。

社会网络对民间金融风险的作用——基于社会网络结构的理论与实证分析

社会网络对民间金融风险的影响已被广泛认可,但是,究竟什么样的网络结构有抑制风险的作用,什么样的网络结构有扩增风险的作用？以资金互助会为例,将互助会涉及的社会网络按结构特征分为单个会的会内网络和多个会的会间网络,研究可知：（1）越紧密的会内网络结构以及越大的网络规模越有利于民间金融风险的控制。（2）跨会网络具有抑制和扩增风险两种作用,它是协同监督和惩罚机制生效的基础,因而对风险具有控制作用,但这种作用只在中介成员为会首时才显著;同时,它也构成了风险传播的通道,导致资金被分散到多个会中,因而提升了系统性风险。     

论鲜卑段部的源流和兴衰

段部出于东部鲜卑,其远祖为先秦时期的屠何,早期活动于徒河地区,北朝时段部与慕容部、乌桓又同称为徒何。段部的兴衰与晋末十六国时期的政局变化有着密切关系,段部与司马越、王浚结援,在司马越当政之时而走向强盛,随着司马越集团的败亡及临敌石赵、慕容燕的崛起而逐渐走向衰亡。同时,段部的兴衰也对晋末十六国政局产生了很大影响。
