Two new estimators for the proportion of true null hypotheses in multiple test

In multiple hypothesis test, an important problem is estimating the proportion of true null hypotheses. Existing methods are mainly based on the p-values of the single tests. In this paper, we propose two new estimations for this proportion. One is a natural extension of the commonly used methods based on p-values and the other is based on a mixed distribution. Simulations show that the first method is comparable with existing methods and performs better under some cases. And the method based on a mixed distribution can get accurate estimators even if the variance of data is large or the difference between the null hypothesis and alternative hypothesis is very small.     

Life Course Status and Exchanges of Support Between Young Adults and Parents

The authors investigated intergenerational support exchanges in relation to young adults' life course status. In a sample of 2,022 young adults (ages 18–34 years) in The Netherlands, single young adults reported receiving more advice from parents than married young adults, and those with children of their own received more practical support. Married young adults and young adults with children provided less support to parents than, respectively, single young adults and young adults without children. Congruent with the life course perspective, the authors' findings suggest that the intergenerational support network is both durable and flexible, responding to the resources and needs associated with an individual's life course status.     

The Intergenerational Continuity of Fathers' Absence in a Socioeconomically Disadvantaged Sample

Fathers' absence is a pattern that shows intergenerational continuity, most notably within disadvantaged populations. The process whereby this pattern is repeated across generations is not well understood. Using data from the Concordia Longitudinal Risk Project, the authors investigated pathways between fathers' absence in 1 generation and the experience of fathers' absence by their children. The current sample included 386 socioeconomically at‐risk individuals across 2 waves of data collection: (a) when they were children and (b) when they were adults with their own children. Analyses based on structural equation modeling revealed that men whose fathers were absent when they were children were more likely to become absent fathers, and women whose fathers were absent when they were children were more likely to have children with absent partners. Indirect pathways between fathers' absence in 2 generations through aggression, education, and substance abuse were illustrated for women. These findings add to the literature suggesting that fathers' absence during childhood has intergenerational effects.     

人口迁移与流动对我国各地区经济影响的实证分析

在对近十年来我国人口迁移和流动的时空演变格局进行初步考察的基础上,文章利用面板数据的变系数模型分别实证考察了人口迁移和流动对我国各地区(省域)经济的影响。结果发现:(1)我国各地区间人口迁移相对平稳,而人口流动在2000年以后呈现出持续快速增长的态势,且空间流向极不均衡;(2)人口的迁移和流动对中国整体经济来说是一个帕累托改进;(3)户籍制度对于发达地区起到了人才沙漏的作用;(4)对于中部的绝大部分地区以及西部的一些人口输出大省,伴随人口迁出而引起的人力资本流失对当地经济的负面影响开始凸显出来,人口流出虽然基本出现一个正面影响,但对本地经济发展的贡献并不如我们预想的那么明显。     

论WTO《SPS协定》“适用地区”条款及我国的对策

WTO《实施卫生与植物卫生措施协定》(Agreement on the Application of Sanitary and Phytosani-tary Measures,简称SPS协定)第六条"适应地区条件"将地区划分为"疫病非疫区"和"低度流行区",由于该条在解释上留有一定的弹性并且国际社会缺乏统一的规范文件,致使适用时出现了许多问题。该条规定的价值取向是既要保护本国或地区内的人员或动植物免受其他地区病虫害之威胁,又要促进成员方国际贸易的发展。要同时实现这两种目标,建立病虫害非疫区并赋予成员方根据其适当保护水平之需要确定合适的贸易地区之权利不失为一种可行的办法。我国应以SPS委员会的各项相关制度为根据,加强与相关国际组织的联系,积极研究我国主要农产品进出口成员之卫生和植物卫生状况和适当保护水平,在此基础上完善对病虫害非疫区或低度流行区承认的法律制度,促进我国对外贸易的发展。     

巴迪欧的元政治学--一种反政治哲学的姿态

当代政治哲学陷入了判断者和行动者的两难困境,其原因在于：一是它通过商谈的方式达成共识;二是它在政治哲学评判时所遵循的伦理标准和共通感。元政治学解决了政治哲学的这一困境,它独辟蹊径地以数学本体论为奠基,实现了将政治作为真之政治的目的。而实现真之政治需要做的是协调政治与国家、政治与主体和政治与哲学的关系,最终清除一种政治的幻想,走出一条通向真之政治的可能性道路。     

健全党员能进能出机制问题研究

中国共产党的党员能进能出机制,是党在领导中国革命、建设和改革开放的历程中形成和建立起来的,是我们党健康发展的重要条件。《中国共产党发展党员工作细则》更是首次提出慎重均衡发展中共党员。但目前,一些地方的做法与当前党员队伍建设面临的新形势、新情况还存在不相适应的地方,仍然存在党员入口把关不严、党员教育流于形式、党员监督管理虚化弱化、不合格党员处置相对偏软等问题。为此,我们应当从严把入口、强化监管、畅通出口等方面着手,健全党员队伍的进出口机制,保持党的先进性和纯洁性,增强党组织的战斗力。     

沈德潜在“诗教”原则下对唐诗的历史定位

沈德潜一生于唐诗用力甚多,唐诗在其诗学理论中占有重要地位。沈德潜重视诗歌史的梳理,也特别注重各时代诗歌所具有的"诗教"之用。唐诗是他对诗歌史进行溯源辨流的起点,也是其考察诗道兴衰的关结点。通过对诗歌史源流正变的清理,沈德潜将唐诗在诗歌自然流变史中的地位和其在诗道兴衰史中的地位结合在了一起进行考察。在诗歌的自然流变中,唐诗虽然处于诗歌发展之流,但又是诗歌之盛;在"诗教"传统中,它又传承了诗教之正。因此,在沈德潜的诗学体系中,唐诗获得了崇高的诗史定位。     

How Parenting Style Affects False Belief Understanding

This study investigated whether mothers facilitate false belief understanding, and if so, what strategies are particularly relevant. The mothers of 64 3- and 4-year-olds were given questionnaires eliciting information about mother's education, mother's occupation, number of younger and older siblings, the time the child spends with mother, and about how mothers deal with five disciplinary situations with their child. Three variables were positively correlated with belief understanding: age, number of older siblings, and number of times mothers said they would respond to the disciplinary situations by asking the child to reflect on the victim's feelings (How Feel responses). These three variables had an independent effect on belief understanding because each was significant after accounting for the influence due to the other two variables. In contrast, there was no significant positive relation between belief understanding and mothers who engaged their child in general discussion and exploration of the disciplinary issues, or who simply reprimanded the child without discussing the situation. The effects for number of older siblings and How Feel responses remained even after the influence due to the child's age, verbal mental age, time spent with the mother, and number of younger siblings was accounted for. The results are consistent with recent research showing that parent-child relations may be important for theory of mind understanding. More importantly, they provide insight into a specific strategy by which parents may help children learn about mental states.
