Parental leave policies and parents' employment and leave‐taking

We describe trends in maternal employment and leave‐taking after birth of a newborn and analyze the extent to which these behaviors are influenced by parental leave policies. Data are from the June Current Population Survey (CPS) Fertility Supplements, merged with other months of the CPS, and cover the period 1987 to 1994. This time span is one during which parental leave legislation expanded at both the state and federal level. We also provide the first comprehensive examination of employment and leave‐taking by fathers of infants. Our main finding is that leave expansions are associated with increased leave‐taking by both mothers and fathers. The magnitudes of the changes are small in absolute terms but large relative to the baseline for men and much greater for college‐educated or married mothers than for their less‐educated or single counterparts. © 2009 by the Association for Public Policy Analysis and Management     

西部高校毕业生求职难度影响因素的实证研究——基于社会资本、人力资本与物质资本的比较研究及其交互效应

本研究旨在考察社会资本、人力资本与物质资本及其交互变量对高校毕业生求职难度的影响。实证分析发现:社会资本、人力资本与物质资本对高校毕业生职业获得难度存在显著的影响。在搜寻成本模型中,社会资本同人力资本的交互项对高校毕业生在求职过程中的搜寻成本存在正向影响,即社会资本欠缺者,可以通过提升人力资本以降低搜寻成本;在求职结果模型中,社会资本同人力资本的交互项对高校毕业生的最终求职结果存在负向影响,即社会资本欠缺者,可以通过提升人力资本以提高求职成功的概率,从而降低求职难度。     

新失业国企工人“城市游民”趋势研究——以郑州市为例

本文通过对游民的发展历史和概念探讨,重新界定了城市游民。认为从基本生存状态和谋生方式来看,脱离国企后的新失业国企工人,"游"的特性较为显著,出现向"城市游民"的发展趋势。但由于市民身份的优势,其稳定性和安定性又是游民所不具备的,他们又具有重新稳定下来的可能。     

从嫉妒到怨恨——论中国社会情绪氛围的一个侧面

任何一个社会不仅具有特定的客观结构和发展水平,也有独特的精神风气和心态,会有自己的情感律动.中国社会的转型,可以视为一个政治激情转化为利益追求的过程,但是利益并未彻底驯服破坏性的激情.从改革初期的嫉妒成风到目前重重郁积的怨恨,我们的社会经历了一系列情感基调的演变.嫉妒作为竞争的动力,曾经发挥了特有的历史作用.但随着利益格局相对固定化、社会差异显明化和向上流动机会受到钳制,加之社会性伤害的存在,怨恨成为一种主导性的情绪氛围.社会结构性产物--怨恨的一个不良后果--怨恨批评随之盛行.     

俄罗斯人口危机及其发展趋势

俄罗斯社会目前正经历着一场旷日持久的并且还在不断加剧的非战争因素人口危机。全国人口灾难性地持续减少,人口自然增长率连续十多年呈负数,人口构成急剧老化,社会劳动力储备日益萎缩。这场危机将严重影响俄罗斯民族的生存能力和俄罗斯联邦国家的精神状态,同时还将严重制约俄罗斯的经济发展和科技潜力、军事潜力的发挥,并不可避免地在很大程度上削弱其国际影响力。     

Development and Impacts of the Customs Union of Russia,Bdarus and Kazakhstan

In recent years, the Eurasian Economic Community has developed rapidly, 1 and it has entered a substantive cooperative period. On January 1, 2010, Russia, Belarus and Kazakhstan decided to launch the Customs Union within the framework of Eurasian Economic Community, and in July the three countries adopted unified customs tariffs. They removed the customs borders between each other beginning from July 2011. Then on January 1, 2012, the three countries launched their Common Economic Space. At the same time, the supranational Eurasian Economic Commission for the promotion of the integration process of the three countries also came into effect. On December 24, 2013, the Supreme Council of the Eurasian Economic Commission meetin~ was held in Moscow.     

硒对慢性氟中毒鸡免疫组织中Cu-Zn-SOD活性及其mRNA表达的影响

为探讨硒对慢性氟中毒鸡免疫组织中Cu-Zn-SOD活性及其mRNA表达的影响,将8日龄海蓝褐雏鸡随机分为3组正常对照组,高氟组,硒拮抗组.分别于分组饲养后第30、60、90 d检测血清和免疫组织中MDA含量、Cu-Zn-SOD活性以及免疫组织中Cu-Zn-SOD mRNA的表达水平.结果,血清及免疫组织中硒拮抗组较高氟组MDA含量降低,试验中后期Cu-Zn-SOD活性较高氟组高,免疫组织中硒拮抗组Cu-Zn-SOD mRNA表达水平明显高于高氟组的水平.结果显示,氟可诱发鸡免疫组织氧化损伤,降低Cu-Zn-SOD活性及其mRNA表达水平;硒可提高Cu-Zn-SOD活性及其mRNA的表达水平,干预免疫细胞脂质过氧化反应,进而减轻氟所致的免疫损伤.
