Why Youths Drop out of High School: The Impact of Preferences,Opportunities, and Abilities

In this paper, we develop and structurally estimate a sequential model of high school attendance and work decisions. The model's estimates imply that youths who drop out of high school have different traits than those who graduate—they have lower school ability and/or motivation, they have lower expectations about the rewards from graduation, they have a comparative advantage at jobs that are done by nongraduates, and they place a higher value on leisure and have a lower consumption value of school attendance. We also found that working while in school reduces school performance. However, policy experiments based on the model's estimates indicate that even the most restrictive prohibition on working while attending high school would have only a limited impact on the high school graduation rates of white males.

新时期浦东群体性事件及其应对能力分析

经济社会快速发展过程中,群体性事件上升对基层政府应急管理能力提出严峻挑战。当前,浦东政府在应对群体性事件的理念、方式、体制、善后反思等方面还存在一定缺失。近年来,浦东政府不断提高应急管理能力,在树立人本观念,不断整合管理机制、多途径解决群体性事件方面下功夫,并注重学习和体制革新。浦东群体性事件化解的缓解率不断提高,其经验对我国其他地区妥善处置群体性事件具有重要的借鉴意义。

风险·制度化：“网络群体性事件”症候表征与治理分析

伴随着互联网的全球化,人类正行走于一个高风险的社会.现代性展开的激烈变化正深刻地影响着我们的生活,特别是2009年,"网络群体性事件"由先前间隙性"上演"转呈集体性"井喷"的网络态势,不仅使得网络言论力量继续成为业界、学界关注的焦点,而且当下由网络群体性事件引起的网络舆情已然介入了现实并对现实,尤其是对政治领域运作形成了从未有过的压力.本文正是立足风险社会的视角,通过对近期频繁出现的网络群体性事件生成背景的考察,以及原因分析,在此基础上深化对由此引发的网络舆情的认识和理解,并提出规范与引导举措.同时指出能否将网络群体事件的治理纳入制度化框架,这既是发挥网络舆论与现实社会良性互动关系的关键,也是对治理者治理智慧的极大考验.     

Who intermarries in Britain? Explaining ethnic diversity in intermarriage patterns

This paper investigates trends, patterns and determinants of intermarriage (and partnership) comparing patterns among men and women and among different ethnic groups in Britain. We distinguish between endogamous (co‐ethnic), majority/minority and minority/minority marriages. Hypotheses are derived from the theoretical literatures on assimilation, segmented assimilation and opportunity structures. The empirical analysis is based on the 1988–2006 General Household Surveys (N = 115,494). Consistent with assimilation theory we find that, for all ethnic minority groups, the propensity to intermarry is higher in the second generation than in the first. Consistent with ideas drawn from segmented assimilation theory, we also find that substantial differences in propensity to form majority/minority marriages persist after controls for individual characteristics such as age, educational level, generation and length of residence in Britain, with men and women of Indian, Pakistani or Bangladeshi background having higher propensities to form endogamous partnerships. However, we also find that opportunity structures affect intermarriage propensities for all groups alike, with individuals in more diverse residential areas (as measured by the ratio of majority to minority residents in the area) having higher likelihood to form majority/minority partnerships. We conclude then that, beginning from very different starting points, all groups, both minority and the majority groups exhibit common patterns of generational change and response to opportunity structures. Even the groups that are believed to have the strongest community structures and the strongest norms supporting endogamy appear to be experiencing increasing exogamy in the second generation and in more diverse residential settings. This suggests that a weak rather than a strong version of segmented assimilation provides the best account of British patterns.     

"国剧运动派"的群体构成及文化心态考察

国剧运动研究难以有新突破的原因主要在于过于依赖文本的分析,研究方法比较单一。本文把国剧运动看作一种流派,从社群流派的角度对国剧运动派的成员构成进行分析,从而揭示出国剧运动派内部两种不同的文化心态,并在此基础上进一步对这两种心态的形成进行深入探讨。     

朝鲜义勇军的活动与中国朝鲜族历史的联系

朝鲜义勇军的前身是朝鲜义勇队,基本队员是东北朝鲜族青年,其主力转移到太行山后,改组为朝鲜义勇军,配合八路军抗战。根据形势发展,在延安组建了延安朝鲜革命军政学校,优秀的朝鲜族革命干部承担主要的领导和培养工作。日本投降后,朝鲜义勇军挺进东北,一部去朝鲜,剩下的被编成三个支队,在朝鲜族聚居区进行活动,促进了朝鲜族社会历史的发展。     

日本帝国主义对中国朝鲜族奴化教育体系的形成过程

日本帝国主义在“9.18”事变以前建设灌输亲日思想的教育机构及“怀柔”朝鲜族知识分子和“有志绅士”;在“9.18”事变以后采取废除朝鲜族私立学校及修改教育内容等强硬措施,从而构建了比较完整的殖民地奴化教育体系。     

基于无标度网络的绿色出行选择行为研究

随着我国城市化进程的加快,机动车污染已成为我国城市空气污染的一个主要来源,提倡绿色出行的理念有助于缓解机动车尾气带来的空气污染,那么对于有限理性个体在复杂社交网络中的绿色出行行为意愿的研究以及群体行为的演化则成为了本文的研究焦点。本文基于计划行为理论等建立了基于个体行为态度、感知行为控制、主观规范及行为结果感知等影响因素的个体绿色出行行为意愿模型,运用观点传播动力学及无标度网络构建了个体选择行为交互网络模型。实证及仿真分析表明,个体行为态度因素在居民的绿色出行行为意愿中取值很高,作用显著,行为感知因素则影响较为有限,提高行为结果感知因素与主观规范因素的取值是提高居民绿色出行行为意愿的主要途径;在择优连接原则与网络增长假设条件下,整个网络向着几个中心节点聚集的趋势越来越明显,即网络节点中心化的程度越来越显著;在社会网络中,提高行为主体的信息交互阈值取值、增加行为主体绿色出行交通费用的折扣系数、提升民众采取绿色出行方式时的精神满足感、塑造宣传绿色出行的意见领袖将有利于提高居民的绿色出行行为意愿。
