Satisfaction With Work and Family Life: No Evidence of a Cultural Reversal

Hochschild (1997) argued that in recent decades the rewards of work have increased relative to those of family life and that this cultural reversal has aggravated the time bind that families face by increasing working hours. To the contrary, pooled data from the 1973–1994 General Social Surveys indicate that in working families, women have shifted away from finding work more satisfying than home toward finding home a haven. Moreover, were it not for women's growing labor force participation and the changing distribution of marital status, the shift would have been even larger. Men's relative work–home satisfaction has been stable. Finally, finding work a haven is unrelated to weekly working hours, and it has not contributed to any increases in working hours over time.

16-18世纪间西欧的激进思潮与近代国家的形成

16—18世纪间西欧出现过各种各样的激进思潮,这些思潮在西欧近代国家形成中均起过重要作用。我们习惯上较多地重视某些思潮,认为这些思潮起主导性的作用,这有一定的道理,但也易于造成一些片面的认识。各种被认为非主流的激进思潮的传播和实践,同样在西欧近代国家形成过程中起过重要作用。只有这样来看问题,我们才能真正认识西欧近代国家形成的特点。

Family Trends and Transracial Adoption in the United States

Several demographic trends have changed family formation in the United States resulting in fewer babies being made available for adoption. At the same time the number of transracial adoptions appears to be increasing. We use the 5% Public Use Microdata Sample of the 2000 census and the National Survey of Adoptive Parents to examine the social and demographic characteristics of those who adopt transracially. Transracial adoption of Hispanic and Asian children, but not Black children, is associated with higher income and education levels. It is less likely in the South, but more likely among those who have had military experience.     

Adoptions, 2000–2001

ABSTRACT

The number of domestic adoptions has remained relatively constant over the past 15 years, varying between 121,000 and 127,000, but placements have increasingly been completed by public agencies. Adoption of foreign-born children in the United States has nearly tripled in the past 20 years. Despite the increased national interest in adoption in the past decade and the efforts of many dedicated individuals and agencies, it is still difficult to determine the total number of adoptions in the United States. No one agency is charged with compiling adoption information on all adoptions in the United States, and the agencies that do have access to some types of adoption information have no mandate or incentive to compile that information so that it could be integrated with other sources of adoption information.     

基于共词网络的我国金融创新研究趋势分析

以共词网络分析作为研究方法,通过绘制知识网络图,对近7年来国内和金融创新的代表性研究相关的文献进行了文献计量分析,识别了国内目前金融创新管理领域的研究热点与连通点,分两个阶段,通过可视化分析阐述了近年国内金融创新的研究趋势。研究结果显示:在2005—2009年期间,金融危机是主要的研究背景,并且在2010—2011年期间,金融危机的控制力继续上升;2005—2009年期间,金融机构是主要的研究对象,但在2010—2011年期间,金融机构研究减弱。两阶段的比较显示,金融监管越来越成为研究的热点,金融产品、金融风险、基金等知识点越来越成为金融创新研究知识网络的信息连通点,决定未来研究的发展方向;现阶段,国内金融创新研究主要包含金融监管、金融危机、金融机构、资产证券化、金融风险等9个主题。     

The Single-Father Family

SUMMARY

This paper examines the demographic and economic characteristics of single-father families, with particular attention to public transfer receipt. Cohabiting and non-cohabiting single fathers are examined and compared to fathers in married-couple families. Estimates from the 1997 March, Current Population Survey (CPS) are featured. Selected trend data for 1984, 1989, and 1996 are also presented. The analyses show that single fathers earn substantially less than married fathers, have lower household incomes, are less educated, and are substantially more likely to be receiving public transfers. Further, the socioeconomic gap between single and married fathers has been increasing since 1984.
