OBJECTIVES: To examine public response to a telephone screener used to identify a probability sample of lesbians, gays, and bisexuals. METHODS: A telephone screener was designed to provide a representative sample of self-identified lesbians, gays, and bisexuals (LGB) in the 30 central cities of the 15 largest Consolidated Metropolitan Areas. RESULTS: Of 14,458 households contacted, 11,612 completed at least part of the survey. Of these, only 2.6% refused or responded "don't know" to the sexual orientation screener question. Respondents from the northeast were more reluctant to answer than respondents from the west. CONCLUSIONS: The use of a screener on a national telephone survey to screen households for self-identified lesbian, gay, and bisexual adults was a successful way to generate a representative sample.  相似文献

Asperger's syndrome (AS) as a diagnostic category has gained enormous popularity and the label is being applied with increasing liberality. While greater awareness of the disorder may be of advantage to certain children and their families, we argue that the over‐inclusive use of the diagnosis may also lead to professional conflicts and ethical dilemmas. Perhaps most concerning of these is that diagnostic ‘generosity’ may exclude children from treatments they would have received if an alternative formulation had been considered. We present clinical scenarios, with special consideration of contextual and intergenerational influences on the children's early lives, and offer alternative conceptualisations. We argue that the new ‘epidemic’ of Asperger's should not be allowed to compromise our professional standards. Assessment should always include a detailed family and developmental history. Finally, we would be interested in feedback from clinicians working in this field.  相似文献

Arguments for historical turning points are sometimes put forward as a principled argument against causal determinism of the course of world history; sometimes as clever curiosities and flights of imagination. I will attempt to show that the logic of turning-point arguments does not disprove historical causality but, on the contrary, depends on belief in causality. Sometimes, this is only an implicit belief in the clichés of folk historiography; occasionally, a serious sociology is explicitly invoked. In either case, there is a tendency to misperceive how historical causality works through broadly-based processes that are not easily stopped or drastically diverted by particular events.  相似文献

Industrial restructuring and changing population composition frequently have been treated as competing explanations of growing U.S. income inequality. Using the Gini coefficient, we employ a model of conditional change to explore the relative effects of each on changes of family income distribution between 1970 and 1990, across 784 metropolitan areas and public use microdata areas (PUMAs). Changes in both industrial structure and population characteristics are found to have significant and opposite effects on family income distribution, although there are sharp differences by decade in the dynamics that underlie increasing inequality. Our central conclusion is that it is too soon to eliminate deindustrialization as a significant cause of increased earnings inequality.  相似文献

You can go home again: Evidence from longitudinal data   总被引:2,自引:0,他引:2

In this paper we analyze the economic and demographic factors that influence return migration, focusing on generation 1.5 immigrants. Using longitudinal data from the 1979 youth cohort of the National Longitudinal Surveys (NLSY79), we track residential histories of young immigrants to the United States and analyze the covariates associated with return migration to their home country. Overall, return migration appears to respond to economic incentives, as well as to cultural and linguistic ties to the United States and the home country. We find no role for welfare magnets in the decision to return, but we learn that welfare participation leads to lower probability of return migration. Finally, we see no evidence of a skill bias in return migration, where skill is measured by performance on the Armed Forces Qualifying Test.  相似文献

A number of prominent demographers have recently reiterated the argument that a lasting mortality decline is a key determinant of the fertility transition. Of the main hypothesized pathways linking fertility to mortality, the one least studied is the insurance hypothesis: the notion that, in high‐mortality contexts, people decide to have more children in order to anticipate possible future child deaths and lessen the risks of having too few surviving offspring. In‐depth interviews and focus groups from Zimbabwe and Senegal are used to examine this hypothesis and to extend it into a broader theory of reproductive decision making under uncertainty. Whereas insurance strategies are frequent in Zimbabwe and occur in urban Senegal, in the higher‐mortality settings—the rural Senegalese site and the recent past described by respondents in Zimbabwe and urban Senegal—deliberate fertility‐limitation strategies are rare. The data depict fundamental changes in attitudes, strategies, and behaviors concerning family size over time and, in Senegal, over space. Important reproductive goals and risks extend far beyond numbers of children and mortality. Parents seek to have healthy, successful children for many reasons including companionship, descendants, and old‐age support. Diverse investments in child quality (their education, health, etc.) and quantity (numbers of births) are the main means to attain these goals and, less recognized by demographers, are also important ways for parents to manage uncertainty in family‐building outcomes; the “classic” insurance mechanism is only one, often minor, aspect of the quantity option.  相似文献
