In recent years, there has been a marked increase in the demand for global data on historical family systems, both in the social sciences and in the humanities. Until lately, however, scholars interested in historical global family variation had to rely on simplified and often ahistorical world-scale classifications of family systems by world geographic regions. This article communicates Mosaic to the scholarly community – one of the largest infrastructural projects in the history of historical demography and family sociology. The article provides a brief history of the project, a discussion of the main issues involved in creating the database (including sampling and representativeness), and Mosaic's data structure and coverage. In the remainder of the article, the authors provide an overview of methodological and research opportunities that the project can offer to scholars, showing how the most pertinent problems of historical family demography can be tackled in more systematic ways than previously.  相似文献

近年我国道路交通安全的总体趋势虽然在转好,但仍然呈现出交通事故总量大、死亡人数多的特点。为切实改善这种状况,应借鉴国外经验,在我国构建区域道路交通事故紧急救援服务体系,提高交通事故信息传递、现场急救和急救转运等方面的综合反应和处理能力。  相似文献

证券市场是最具吸引力的经济领域之一,同时,证券市场是信用制度和市场经济发展到一定阶段的的产物,是风险高度集中的市场,具有风险来源广、传导性强和社会危害性巨大的特点。经过十几年的发展,我国证券市场无论在总量还是结构方面,都取得了长足的进步。证券市场的稳健有序发展与高效实用的证券监管体制密不可分。证券市场的监管是证券市场存在和发展的基石,是国家规范证券市场的有效手段。我国已依法建立了对证券市场的集中统一的监管体制,但目前的监管现状与证券市场的飞速发展的现实要求间存在一定的差距。本文以我国证券市场监管的现状为基础,分析目前市场监管存在的主要问题,提出相应的完善对策,以期通过建立有效的监管,极大的提高证券市场运行效率,防范和化解风险,使证券市场更好的为国民经济服务。  相似文献

Biotechnology, rather than being defined as a distinct industry like steelmaking or shipbuilding, is instead a scientific knowledge base—a rapidly evolving technology—that has economically valuable applications in such diverse industries as pharmaceuticals, medical diagnostics, agriculture, bioenvironmental remediation, and chemical processing. Biotechnology has captured the imagination of ambitious scientific investigators and investors seeking high rates of return, as well as state economic development officials who hope to anchor the industry in their locality and reap the industry's economic and employment rewards. Biotech is still at an early stage of its development, and there are many competing hypotheses about its future development. Most importantly, biotechnology involves the commercialization of science resources in which the federal and state governments have made substantial investment. One key question is how to leverage this investment for future economic growth. This article explores the policy issue related to the commercialization of biotechnology, its role as an engine of economic development, and the appropriate public policy response.  相似文献

试析对区域性国际组织运用武力的法律控制   总被引:2,自引:0,他引:2  
区域组织运用武力问题在科索沃战争后更为引人关注。在联合国宪章体系下 ,区域组织运用武力有三种类型。其中 ,集体自卫和授权型运用武力对及时有效地反对地区霸权主义、维护国际和平与安全具有重要意义。但从国际关系实践来看 ,区域组织运用武力尤其是授权型运用武力存在着较多问题 ,只有对其实行有效控制 ,才能发挥区域组织在维护国际和平与安全方面的作用  相似文献

自主性是学科体系和知识体系的内在特性,强化学科自主性是贯穿于改革开放以来中国工会理 论研究的基本线索,是工会学作为独立学科的本质性规定。工会学的研究对象、学科基础和知识疆域有其自身 的独特性,这种独特性是由中国工会的历史传统、价值内核、指导思想、组织原则、结构特征和制度精神等因 素共同决定的,这是设置工会学学科的基本依据。在马克思主义理论一级学科下设置工会学学科,是中国工运 事业和工会工作的一件大事,这对于开辟马克思主义工会学说中国化时代化新境界,推进中国特色社会主义工 会发展道路守正创新,构建中国工会自主知识体系具有重大的现实意义和深远的历史意义。  相似文献

This paper presents the results and policy implications of a study that examined the spawning of founders who had previously been employed at large corporations. We found that spawning of founders is positively associated with the parent companies' productivity, innovativeness, and headquarter location. Furthermore, we found that the spin‐off per employee rate is higher in smaller establishments. We also found that the local entrepreneurial culture is significant in explaining local spawning of founders. Finally, we present new empirical evidence on the crucial role of successful homegrown companies in regional cluster development. More specifically, we found that the existence of successful homegrown companies is significantly correlated with the level of the regional entrepreneurial activity. This finding is consistent with the finding of many cluster development case studies. Thus, we argue that successful homegrown companies have a unique role in cluster development. This role can seldom be replaced by nonhomegrown companies. This is related to the notion that prior to the development of an entrepreneurial cluster, some intangible precondition should be realized such as the appearance of local role models and a shift toward a more entrepreneurial culture. In a more general perspective, these results support the notion that knowledge‐based regional development is a complex process that requires a long‐term and continuously adjusting supporting policy rather than being based mainly on attracting established companies' R&D centers to the region.  相似文献

Individuals' preferences for automobiles are often taken for granted in our auto centric society. This study attempts to determine if commuters in a city located beyond the fringe of a metropolitan area are willing to use public transit if it is developed and what are the socioeconomic and attitudinal factors that influence individuals' decision to use such a service. Analyses of survey data reveal that preferences exist for public transit service, which can be partly attributed to individuals' concerns regarding rising gasoline prices and air pollution, and is particularly noticeable among those who are educated and/or belong to a younger age group.  相似文献

俄罗斯工会在苏联解体之后经历了由计划经济到市场经济的转变,最终形成了社会统合主义的 模式。本研究在梳理俄罗斯工会改革历史的基础上,根据统合主义理论分析了俄罗斯工会在与政府的关系、对 工人利益的代表性和自身行动能力 3 个方面的现实情况。研究认为,俄罗斯工会在改革初期复杂、动荡的政治 经济背景下所追求的自由主义模式受历史因素影响并不成功。改革的转机出现在统一俄罗斯党成立之后,俄罗 斯工会与政府关系迅速改善,并在执政党的同情和支持下提升了自身对工人利益的代表性和行动能力,特别是 运用法律武器的能力。但俄罗斯工会也面临着新就业形式和移民劳工增长的挑战,还需要进一步的改革以适应 劳动力市场的复杂变化。  相似文献
