Migrant women’s economic success in Russia: objective reality and subjective assessment

This study contributes to the growing body of literature on the outcomes of labour migration by focusing on the effects of migrant legal status on the economic and perceptual measures of migration success. To study the effects of legal status, we use a sample of Central Asian migrant women who work in Russia and of their native counterparts who occupy the same positions on the labour market. Similar to the studies in the developed settings, we find that a temporary legal status is associated with an earnings penalty and that permanent legal status corrects this earning disparity. We also find that both temporary and permanent migrant status is positively associated with perceptions of pay inequality but that, irrespective of these perceptions, both types of migrants are more likely to be satisfied with their jobs than natives. We interpret these findings within the legal and social context of migrant economic incorporation in Russia and relate them to the findings from other migrant-receiving settings.     

基于Petri网的微博网络信息传播模型

微博网络中的信息传播模型是分析用户行为，找出传播路径，确定领袖人物，发现舆情热点等研究的基础。虽然多种不同角度的信息传播模型已经得到广泛研究，但缺乏对信息动态传播过程的直观描述。本文基于Petri网的结构和特征，针对微博网络信息传播过程，提出了一种简单直观的描述模型，该模型首先对微博网络的信息动态传播过程中的对象进行结构化描述。本文根据微博网络的用户结构关系，并利用Petri网的相关理论，形式化解释和定义信息传播基本对象，从而更加直接描述了微博网络中的转发、评论、回复等多种用户行为。在此基础上，本文利用Petri网能够描述信息流动问题的特征，结合颜色Petri网和时延Petri网，从Petri网系统的角度表示信息动态传播路径，并研究网络的动态性质和传播条件，使得信息传播模型更加真实地模拟信息传播情况。最后本文分析信息传播算例和新浪微博真实数据实验，验证了模型的有效性和可行性，为舆情态势分析以及用户行为的研究提供帮助和支持，同时也为其它社交网络信息传播的用户行为描述提供了新的思路。     

Heteroscedastic Global Tests that the Regression Parameters for Two or More Independent Groups are Identical

Simulation results are reported on methods that allow both within group and between group heteroscedasticity when testing the hypothesis that independent groups have identical regression parameters. The methods are based on a combination of extant techniques, but their finite-sample properties have not been studied. Included are results on the impact of removing all leverage points or just bad leverage points. The method used to identify leverage points can be important and can improve control over the Type I error probability. Results are illustrated using data from the Well Elderly II study.     

君主专制与政治抵制:早期现代英国法律语境中的《复仇者悲剧》

英国自都铎王朝后期至斯图亚特早期，立宪君主论或混合君主论者抵制君权神授论，坚持家庭是一个自治的、涉及臣民私人权益的小政府，受到自然法、古代宪法或神圣法的保护。《复仇者悲剧》中公爵王室言行映射詹姆士一世在《皇家礼物》中所宣扬的君权神授论，温迪斯兄弟俩及追随者的复仇隐含当时的政治抵制学说，公爵王室与温迪斯兄弟俩的对立象征君权神授论与普通法理论的对峙。温迪斯兄弟俩却以威胁新君为由被处死，司法斗争简约为复仇冲动，维权英雄陡变为暴徒，暴君化身为明君，这暴露出君权神授论的悖论性和剧作家含混的复仇伦理。     

德行领导对员工创新行为的影响---工作繁荣与情感承诺的作用*

研究表明，德行领导作为家长式领导的核心维度，对员工行为有重要影响，但现有研究忽视了员工工作状态的重要作用。本文基于自我决定理论，以员工工作繁荣为中介，探讨德行领导对员工创新行为的影响，并从社会认同的情感视角出发，考察了情感承诺在上述关系间的调节作用。研究表明，德行领导对员工工作繁荣与创新行为均存在显著正向影响；员工工作繁荣对其创新行为存在显著正向影响；员工工作繁荣在德行领导与创新行为之间起部分中介作用；情感承诺调节了德行领导对员工创新行为的影响，情感承诺越高，德行领导对员工创新行为的影响越显著。     

美国师德问责体系的结构、特点及启示——基于德克萨斯州的经验

美国德克萨斯州历来重视教育工作者的职业道德建设，建立了一系列教育工作者违规行为问责机制，形成了较为完善的师德问责体系。美国德克萨斯州的师德问责体系具有独特的结构与特征。颁布《教育工作者伦理规范》，使问责有法可依；设立专门机构，使问责主体明确；细化教师违规行为，使问责有据可凭；强调证据证词，使问责合理科学；重视结果多样，使问责责罚分明。这些对于促进我国师德问责的规范化、制度化发展有着积极的借鉴意义。     

Beyond Piketty: A new perspective on poverty and inequality in India

The socio-economic literature has focused much on how overall inequality in income distribution (frequently measured by the Gini coefficient) undermines the “trickle down” effect. In other words, the higher the inequality in the income distribution, the lower is the growth elasticity of poverty. However, with the publication of Piketty’s magnum opus (2014), and a subsequent study by Chancel and Piketty (2017) of evolution of income inequality in India since 1922, the focus has shifted to the income disparity between the richest 1% (or 0.01%) and the bottom 50%. Their central argument is that the rapid growth of income at the top end of millionaires and billionaires is a by-product of growth. The present study extends this argument by linking it to poverty indices in India. Based on the India Human Development Survey 2005–12 – a nationwide panel survey-we examine the links between poverty and income inequality, especially in the upper tail relative to the bottom 50%, state affluence (measured in per capita income) and their interaction or their joint effect. Another feature of our research is that we analyse their effects on the FGT class of poverty indices. The results are similar in as much as direction of association is concerned but the elasticities vary with the poverty index. The growth elasticities are negative and significant for all poverty indices. In all three cases, the disparity between the income share of the top 1% and share of the bottom 50% is associated with greater poverty. These elasticities are much higher than the (absolute) income elasticities except in the case of the poverty gap. The largest increase occurs in the poverty gap squared – a 1% greater income disparity is associated with a 1.24% higher value of this index. Thus the consequences of even a small increase in the income disparity are alarming for the poorest.     

A class of symmetric bivariate uniform distributions

A class of symmetric bivariate uniform distributions is proposed for use in statistical modeling. The distributions may be constructed to be absolutely continuous with correlations as close to±1 as desired. Expressions for the correlations, regressions and copulas are found. An extension to three dimensions is proposed.     

青史凭谁定是非——评宋齐丘的历史功过

宋齐丘一生历经磨难和坎坷，曾四为宰相，贵为三公，助徐知诰“兴利除害，变更旧法”，并提出和推行了具有远见卓识的税制改革，戮力劝农，对吴、唐社会经济的发展作出了巨大的贡献，推动了历史的前进。他从此居功自傲，挟旧邀功，贪权固位．并长期卷入朝中朋党之争，最终葬送了自己。宋齐丘一生有功有过，但功大于过，是值得充分肯定的，应给其以公正的历史评价。
