Although sociologists, demographers, and economists are generally agreed that economic independence enhances the likelihood that men will marry, there is disagreement concerning its effect on women. The view that economic independence weakens women's incentive to marry has probably been the most influential, although it has been subjected to few rigorous empirical tests with individual-level data. In the present paper we examine the predictors of forming a first cohabiting union, of progressing from this union to marriage, and of marrying without previously cohabiting by applying hazard regression to event-history data from the 1992 Swedish Family Survey, supplemented by earnings data extracted from the national taxation register. We test a battery of measures that reflect people's past, current, and potential attachment to the labour market. We find that the correlates of union formation for women are largely indistinguishable from the correlates of union formation for men, and that far from being less likely than other women to cohabit or to marry, women with a greater degree of economic self-sufficiency are more likely to do so.  相似文献

Allen et al.’s results depend on their inclusion of children whose family at the time of their grade retention is unknown, plus adopted and foster children whose selection process into families is unknown. Children whose family has been through upheavals or transitions are less likely to make good progress in school than children from stable families. Children raised by stable same-sex couples do remarkably well in school.  相似文献

In mid-demographic-transition, many Asian countries enjoyed a large demographic ‘dividend’: extra economic growth owing to falling dependant/workforce ratios, or slower natural increase, or both. We estimate the dividend, 1985–2025, in sub-Saharan Africa and its populous countries. Dependency and natural increase peaked around 1985, 20 years after Asia. The UN projects an acceleration of the subsequent slow falls but disregards slowish declines in young-age mortality and thus, we argue, overestimates future fertility decline. Even if one accepts their projection, arithmetical and econometric evidence suggests an annual, if not total, dividend well below Asia's. The dividend arises more from falling dependency than reduced natural increase, and could be increased by accelerating the fertility decline (e.g., by reducing young-age mortality) or by employing a larger workforce productively. Any dividend from transition apart, low saving in much of Africa (unlike Asia) means that, given likely natural increase, current consumption per person is unsustainable because it depletes capital per person.  相似文献

Alcohol use is pervasive in adolescence. Though most research is concerned with how friends influence drinking, alcohol is also important for connecting teens to one another. Prior studies have not distinguished between new friendship creation, and existing friendship durability, however. We argue that accounting for distinctions in creation–durability processes is critical for understanding the selection mechanisms drawing drinkers into homophilous friendships, and the social integration that results. In order to address these issues, we applied stochastic actor based models of network dynamics to National Longitudinal Study of Adolescent Health data. Adolescents only modestly prefer new friendships with others who drinker similarly, but greatly prefer friends who indirectly connect them to homophilous drinkers. These indirect homophilous drinker relationships are shorter lived, however, and suggest that drinking is a social focus that connects adolescents via proximity, rather than assortativity. These findings suggest that drinking leads to more situational and superficial social integration.  相似文献

The current decision-making model for the review of human research contains inadequate mechanisms to ensure that the interests and perspectives of research participants are considered by Institutional Review Boards, whose decisions may profoundly affect the safety and well-being of participants. As a result, this model is far from being optimized to realize Institutional Review Boards' principal mandate and undermines the credibility of the research review process. This article proposes a procedural mechanism that would ameliorate these systemic deficiencies by allowing “research participant representatives” to give voice to participants during the research review process.  相似文献

Ethical dilemmas are inherently ambiguous, complex, and ill-defined. Additionally, these dilemmas involve multiple stakeholders. These characteristics may induce political behavior as a resolution tactic. Thus, the goal of the present effort was to investigate perspectives on politics among researchers in an ethical decision-making context. A qualitative analysis of interviews with university faculty members revealed that faculty members’ perspectives on political behavior in an ethical decision-making context fall into a number of categories, including positive, negative, and realistic views of political activity. The implications of these varying perspectives on ethical decision making are discussed.  相似文献
