Nationally representative data from the General Social Surveys indicate that from 1988 to 1998 there was an increasing likelihood that American men and women had had a same‐gender sexual partner during the previous year. Increases in same‐gender sexual partnering and decreases in exclusively opposite‐gender sexual partnering during the previous 5 years were also evident among women over the 1988–1998 period. Same‐gender sexual partnering was found to be associated with age, birth cohort, race, size of hometown at age 16, and mothers’ education. The increase in same‐gender sexual partnering over the 1988–1998 period persisted after controlling for these factors. Several possible explanations for the trend are discussed.  相似文献

This article examines the geographical corridors for the establishment of rice in seventeenth-century Dutch Guiana. One corridor of introduction is associated with the expulsion of Dutch planters from Brazil in 1644, whose slaves reestablished longstanding subsistence preferences with their exodus to the colony. Another corridor links its introduction to the African Gold Coast, where rice developed as a commodity during the 1600s. The oral histories of maroons offer an additional perspective on rice beginnings in South America, attributing its diffusion to the deliberate efforts of enslaved women.  相似文献

Before the recent implementation of the Hague Convention requirements on intercountry adoption in Guatemala, most children in the process of being adopted by foreign nationals were cared for by foster parents. In the present study, 16 Guatemalan foster parents were interviewed regarding their experiences with and attitudes toward international and domestic adoption and fostering. Although adoption was generally described in positive terms as a means to improve the child's future, respondents also emphasized the economic dimension of international adoption. Foster parents’ views implied actions that are important for implementation of the Hague Convention requirements, including addressing poverty as the root cause of child relinquishment, reducing structural and attitudinal barriers to domestic adoption, and enlisting the aid of extended families in caring for children. With training and licensing, foster parents themselves might play a role in post-Hague procedures for providing families for children.  相似文献

The use of Charles Ragin’s Qualitative Comparative Analysis (QCA) is increasing in the social sciences. However, some of its characteristics, especially those of its fuzzy set variant, are still not well understood by users. QCA, a set theoretic method, aims to describe, in a Boolean form, the configurations of conditions that are necessary and/or sufficient for some outcome. The calibration of set memberships is a central feature. We discuss how two alternative calibrations of a condition affect the assessment of consistency with sufficiency. Using first an abstract example and then an empirical one from the sociology of education, we explain why “stricter” calibration of conditions results in higher consistency with sufficiency. We demonstrate that conventional truth table analysis is not an ideal way to compare the analytic consequences of alternative calibrations and therefore employ an alternative which allows a more direct comparison of consistency indices while keeping comparative configurational contexts intact.  相似文献

Despite gains in women's status, successful leaders are more likely to be men than women. The styles that successful leaders set tend to be masculine. Female leaders face a paradox: If they emulate a masculine leadership style, their male subordinates will dislike them. If they adopt a stereotypically warmand nurturing feminine style, they will be liked, but not respected. Two experiments found that female leaders who are mindful can escape this paradox. In an experiment, college-aged men perceived a woman who was masculine and mindful to be a better leader than a woman who was masculine and mindless. A second experiment replicated that result with middle-aged businessmen.  相似文献

Recent changes in UK legislation on data protection and confidentiality have affected key aspects of the research process. They have led to much stricter approaches to research governance, leading in turn to more stringent scrutiny by medical ethics committees and National Health Service (NHS) Trusts. Almost all stages of research are affected, from participant recruitment to storage of data, eating into researcher time and consuming significant resources. The resulting constraints are examined in relation to a research programme on development in children with learning disabilities, highlighting the practical and ethical issues arising, with informed consent a particular challenge. Being multidisciplinary, learning disability research has to satisfy numerous regulatory bodies. For participants' rights to be fully respected and for projects to be completed within time and on budget, all contributors to the research process, including funders, need to be aware of the additional implications and demands imposed by the new regulations.  相似文献

This article reviews the literature on the conflicts and presenting problems of mid-life single women wishing to marry and addresses the clinical issues in their treatment. Methodology and findings of a research project conducted by the authors with 49 African-American and White women who married after the age of 35 are reported. There is a review of the sociological and historical context for African-American women, which accounts for the different findings for the two subgroups studied. The paper concludes with recommendations to the clinician working with this population.  相似文献

Relief efforts resulting from the $5 billion Priority Reconstruction Program, launched as part of the 1995 Dayton Peace Agreement, attracted nearly 500 nonprofit organizations to the small, newly independent nation of Bosnia. Donor resources and recipient needs changed over time forcing constant adjustment in this environment, at times resulting in service overlap, inefficiency, and waste. However, the inter-relatedness of tasks in this war-torn country continually reminded players of the need for cooperative, coordinated action. Within a short time, intricate webs of interorganizational relationships emerged among donors, NGO implementers, and host nation players, at both ground and global levels. The research reported here is based on extensive interview material with a diverse range of informants.  相似文献
