Household headship historically has been equated with being the main economic provider of the household, a position usually occupied by men. This paper uses a change in the United States Census definition of household headship to examine whether headship for married women is associated with being the primary breadwinner in a marriage versus other non-economic explanations. According to microdata from the 1990 United States Census, women who are the main income providers in a marriage are much more likely to be household heads than women in co-provider marriages. There also is support for an egalitarian ideology explanation; that is, when both spouses are highly educated, the wife is more likely than the husband to be household head net of her relative economic independence in that marriage. Yet the force of convention remains strong given the low prevalence of headship among married women. The new census definition was meant partly to reflect the changing economic status of women. However, the reality is that conventional gender behaviors persist in household headship. 相似文献

The present review critically evaluates evidence from adoption studies on the heritability of antisocial personality, interactions between genetic predispositions and the characteristics of adoptive mothers and fathers, and both the methodological and diagnostic shortcomings of existing studies. The article concludes with directions and suggestions for future research and practice. 相似文献

This study examines the relationship between employed wives' preferences for household production time, employment time, leisure, and their actual time use. A random sample of 235 employed, married women estimate their time use on an average weekday and weekend day in 13 activities and indicate their preferences for time in those activities. Hierarchical multiple regression procedures are used to examine the relationships between actual and preferred time use. Weekday employment time is not related to preferences for more or less time in household production but wives allocating more time to employment want to spend less time at that employment and more time in leisure. Weekend employment time is related to preferences for more time in leisure, child care, and other household work. Time spent performing household work is not related to preferences for more or less time in any activity except the desire for more leisure time on weekends.Ann Renigar Hiatt is Assistant Professor in the Department of Human Services, College of Education and Allied Professions at the University of North Carolina at Charlotte, Charlotte, NC 28223. Her research interests include employed women's time allocation, time pressures, and use of time management strategies. She received her Ph.D. from the University of North Carolina at Greensboro.Deborah D. Godwin is Associate Professor in the Department of Housing and Consumer Economics at the University of Georgia, Athens, GA 30602. Her research has focused on husbands' and wives' time allocation to household production, the effects of women's employment on family economic functioning, and family financial management. She received her Ph.D. from the University of North Carolina at Greensbore. 相似文献

Two of the most striking characteristics of contraceptive practice in the world today are the wide variation in patterns of use across countries and the tendency of the distribution of use by method to persist or narrow, even as new methods become available. The argument advanced in this article is that the disposition to commit to a reduced range of methods results from positive feedback in the process of contraceptive choice, and follows the logic of path dependence. The positive feedback derives, in large part, from social interaction among both the providers and the users of contraceptive methods. The persistence of outmoded contraceptive regimes is illustrated with the experience of Mexico and Brazil. In each case, it is argued that the conditions, events, and policies in the early stage of the adoption process have had a determinant bearing on the contraceptive practice prevailing in the late 1990s. 相似文献

The author of this article argues that inflation is a neglected area in corporate planning despite the events of 1974/1975. The planning problem which companies face because of inflation is defined, while acknowledging that it is difficult to solve. Recent experience has shown that inflation has a direct impact on every major area of business. Thus it is essential that there is a meaningful attempt to handle these problems in planning. The author discusses his approach to grasping this nettle. 相似文献

近来关于闭环供应链网络的文献中提出了两个重要问题:(1)如何制定平衡环境和经济效益的优化方案;(2)如何深刻理解二者间的效益背反关系。本文认为,针对环境和经济闭的效益边界及其背反关系进行全面探索,可以有效解决环境保护和经济发展中的效益平衡问题。为了解决求解效益边界的多变量问题,本文设计了一个针对目标函数中的数值进行指数计算的生态效益算法,并在德国电子电气设备闭环供应链设计中进行了实证研究。 相似文献
