Spatial effects on individual social capital: Differentiating the constraints of local occupational structures

Recent studies have paid more attention to how position-generated social capital varies by an individual’s characteristics, and less to how geographical distributions of occupations may constrain position-specific connections. By integrating two national surveys from the United States, we differentiate the extent to which individual social capital fluctuates by occupational compositions at the county, metropolis, and state levels. Multilevel analyses show that when more people at all three levels work in education, training, and library occupations, residents have a greater chance to gain access to professional-type resources. Similar spatial effects on farming and production resources, however, are more apparent at the county level. Not only does the association between individual social capital and local occupational structures vary across different occupations, but the magnitude of such spatial effects also differs by the scope of the geographical areas. The findings underscore how contextual factors and geographical location may contribute to building occupation-specific network resources.     

依赖中的资源争夺:中小学生减负的困境及出路

中小学生减负问题是新中国成立以来，我国教育发展过程中力图解决但却难以根治的历史性问题。依赖中的资源争夺所引发的校际与校内关系的复杂存在，影响了减负工作的深入推进，成为中小学生减负路上的主要拦路虎。突破减负困境，可通过推动基础教育从传统静态、集中走向现代动态、均衡发展，确保义务教育阶段公办教育的公共服务能力，重新思考民办与公办教育的关系及功能定位，形成多元主体参与和共建共享的现代教育治理体系，构建低竞争、低控制、真评价的教育生态环境等举措合力助推。希望以此为我国中小学生减负工作的有效开展提供行动借鉴和理论参考。     

National Language Capacity in Global Competition

The term national language capacity refers to the sum total of a nation’s ability to grasp linguistic resources, provide language services, deal with linguistic issues, develop the language, and related tasks. Key capacities include the possession of linguistic resources, utilization of language and language services, development and use of linguistic resources, the language of the members of the nation, reserves of linguistic talent, language management, development of language enterprises and linguistic influence. The development of informatization has made national language capacity an important part of national strength. It is hard power as well as soft power, playing a very important role in social progress and cultural inheritance, in promoting economic development and technological innovation, and in protecting a country’s national security and international development.     

1906-1908年的郑孝胥与预备立宪公会

考虑到我国未来年度的OD分布预测中的路网构成变化、区域经济布局变动、区域经济增长速度差异等一些具有时变性和特殊性因素，采用在“四阶段法”运量预测基础上改进而成的“三阶段法”进行高速铁路短期客运量预测。首先采用组合预测模型进行趋势运量预测，然后采用多元LOGIT模型进行方式分担，最后采用弹性系数诱增模型进行诱增运量预测。以京沪高铁为例，采用“三阶段法”预测了2014年和2015年京沪高铁本线及跨线单向客流量。     

Social capital of entrepreneurs in a developing country: The effect of gender on access to and requests for resources

This paper addresses gender differences in the social capital of entrepreneurs in a developing country. Social networks are often an important asset for accessing resources; however, they may also be a liability in developing countries, since entrepreneurs are often expected to support their contacts. Using a recent survey among urban and rural Ugandan entrepreneurs, we focus on the financial resources that entrepreneurs can obtain from their contacts on the one hand, and requests for financial support made to the entrepreneurs from these contacts on the other hand. Our results show that there are gender differences associated with access to, and requests for, financial resources.     

清代棚民问题侧论

农民背井离乡,到山间开垦并种植山地,开发种种山林资源,以谋生存,被称为棚民.清代棚民,数量庞大.政府为了维持社会稳定,对棚民采取安辑的政策.棚民对山地等山林资源的开发,严重破坏了生态环境,造成了严重的后果.对社会维稳和生态维护的两难选择,包世臣的应对策略,很有意义.     

对华北油田勘探历程的再认识

华北油田是我国最早发现古潜山海相碳酸盐岩油气藏的地方,也是产量骤起骤降幅度最大的一个油田,它的勘探过程中蕴含着太多丰富的经验值得总结.从任4井发现的细节入手进行回顾,对华北油田勘探经验中的古潜山、碳酸盐岩、震旦系灰岩等关键问题进行了深入思考.指出按有机成油论的学说很难将华北油田的历史经验深入总结下去,应按无机成油论的观点,对华北油田的历史经验进行再认识.     

新文类与亚文化

新媒体和文学的结合催生出一批迥然有别于传统纸媒文学的新文类作品,而被流行化的亚文化构成了它们的重要话语资源,新文类中最常见的亚文化种类有同性恋亚文化、神秘亚文化和游戏动漫亚文化等,这些亚文化中蕴涵的抵抗和边缘因素在消费时代成为商业文化的卖点,被流行化快餐化之后作为一种＂奇观＂投合了都市青少年群体追求新奇刺激的猎奇心态,因而在新媒体平台上成为新的时尚和潮流。     

国际资源贸易理论与政策的研究述评

近年来,国际资源贸易发展迅猛,其重要性日益凸显。国际贸易学者从理论与政策两方面对国际资源贸易进行了研究。理论研究涵盖H-O模型对国际资源贸易的解释力、不完全竞争市场下国际资源贸易的分析框架、国际资源贸易产品价格波动的原因与价格弹性估计、国际资源贸易与"资源诅咒"的关系等问题。政策研究主要包括对国际资源贸易实施的出口税、出口配额以及进口关税的经济效应分析等。目前,学术界还没有形成统一的国际资源贸易分析框架,WTO需要把国际资源贸易置于多边贸易体制的规制之下。
