This paper examines a wide variety of forms, and full histories, of family structure to test existing theories of family
influences and identify needs for new theories. The focus is on links between childhood family structure and both completed
schooling and risk of a nonmarital birth. Using a 27-year span of panel (PSID) data for U.S. children, we find that: (a) change
is stressful, (b) timing during childhood is relevant, (c) adults other than parents are important, and (d) two more recently
studied family structures (mother-with-grandparent(s) and mother-with-stepfather) do not fit the molds of existing theories.
The findings suggest that new theories should consider allocation of resources and reasons people group into family structures.

Many linear programming models have been proposed for performing discriminant analysis. Partial characterizations for unacceptable solutions have been presented and new models proposed to circumvent these problems. In this paper those conditions leading to unacceptable solutions for all two-group models are characterized. 相似文献

The term "undone science" refers to absences of scientific research that social movement and other civil society organizations find when attempting to make epistemic claims in the political field. The existing literature has identified various pathways for addressing the knowledge needs of civil society organizations, including asking elected and appointed political leaders to shift funding priorities and directly seeking support and partnerships with scientists. Here, a third pathway is identified and explored: civil society organizations that have the resources to fund their own research. A sample of such "civil society research" from large, mainstream, U.S. environmental organizations demonstrates that although the large organizations do engage in such research, most of it is not published in peer-reviewed journals. The peer-reviewed research is found almost exclusively in large preservation and conservation organizations that have staffs of scientists. Most of the other research reports are oriented toward documenting environmental problems and providing policy and management solutions. The research is highly applied and does not represent fundamental contributions to large mainstream scientific fields. Comparisons with civil society research in the author's previous research projects on religion, health, and economic development are discussed to assess applicability of the concept for other sociological subfields. 相似文献

This study examined the role of three spiritual responses to divorce for psychological adjustment: appraising the event as a sacred loss/desecration, engaging in adaptive spiritual coping, and experiencing spiritual struggles. A sample of 100 adults (55% female) was recruited through public divorce records. Most appraised their divorce as a sacred loss/desecration (74%), experienced spiritual struggles (78%), and engaged in adaptive spiritual coping (88%). Appraisals of sacred loss/desecration and spiritual struggles were tied to higher levels of depression. Adaptive spiritual coping was tied to greater posttraumatic growth. Spiritual coping and struggles each contributed uniquely to adjustment beyond parallel forms of nonspiritual coping and struggles and mediated links between viewing the divorce as a sacred loss/desecration and depression. 相似文献

We reply to the critical comments of Richard Münch and the author group Jansen, Heidler and von Goetz on our article “Emergence of an Academic Elite? The Impact of Universities’ Size and Reputation on Research Funding” published in this journal. After reviewing some other sociologists’ statements on Münch’s thesis about the academic elite we reinforce the gain of our empirical analyses of hypotheses of the sociology of science in general, on the Matthew-Effect, and on trends to a possible cartelization and monopolization in the German science system. The main critic of unsuited data (we used applications for single grants submitted to the German Research Foundation) does not adequately consider the postulated scope of the investigated theses and our analyses do not aim at a general evaluation of the “Initative of Excellence”. 相似文献

Few programs to enhance fathers' engagement with children have been systematically evaluated, especially for low‐income minority populations. In this study, 289 couples from primarily low‐income Mexican American and European American families were randomly assigned to one of three conditions and followed for 18 months: 16‐week groups for fathers, 16‐week groups for couples, or a 1‐time informational meeting. Compared with families in the low‐dose comparison condition, intervention families showed positive effects on fathers' engagement with their children, couple relationship quality, and children's problem behaviors. Participants in couples' groups showed more consistent, longer term positive effects than those in fathers‐only groups. Intervention effects were similar across family structures, income levels, and ethnicities. Implications of the results for current family policy debates are discussed. 相似文献

Ethnic segregation in context: Social discrimination among native Dutch pupils and their ethnic minority classmates 总被引:1,自引:0,他引:1
Social discrimination, defined as the relative preference for intra-ethnic over inter-ethnic relationships, was studied in pupils’ networks in Dutch secondary school classes. While native Dutch pupils (ethnic majority members) mainly named fellow majority members, ethnic minority members reported ties with as many majority as minority members. Considering the ethnic composition of the classroom, however, majority members discriminated less than minorities. No strong effect of classroom ethnic composition on social discrimination was found, whereas neighborhood composition was shown to clearly influence social discrimination: ethnic minority members were more, and majority members less inclined to discriminate in neighborhoods with more ethnic presence. 相似文献
