In a recent article (Frisbie. Forbes. and Pullum 1996) we documented racial/ethnic differences in birth outcomes according to a more fine-grained classification than has typically been employed in the demographic literature. In his commentary, van der Veen focuses on the measurement of one of the dimensions of that classification, maturity of the infant. as proxied by the fetal growth ratio. The crux of the critique is easily seen in van der Veen's statement that “all of my disagreements with Frisbie et al. 's method arise from their particular use of a postnatal standard for the assessment of intrauterine growth.” Our critic misunderstands our objective: He fails to realize our interest in birth outcome, not pregnancy process, and does not perceive that our intent was to extend the research extant in both the demographic and public-health literatures in which patently postnatal (i.e., ex utero) measures are taken as outcomes interesting in their own right and/or as risk factors for infant mortality and infant and childhood morbidity. Specifically, he does recognize that we purposefully expanded our focus to include moderately compromised births to determine if they were at higher risk than the normal births with whom they are conventionally categorized. Our discussion draws on research cited in the original article, on studies cited by our critic, and on a few more recent investigations. Although we have never argued that ours is the only, or even the best, approach in all cases, we try to clarify the rationale for, and adduce additional empirical evidence of, the utility of the method we used. 相似文献

We investigate the extent and implications of cohabitation and marriage among U.S. welfare recipients. An analysis of four data sets (the Current Population Survey, the National Survey of Families and Households, the Panel Study of Income Dynamics, and the National Longitudinal Survey of Youth) shows significant numbers of cohabitors among recipients of AFDC. An even more surprising finding is the large number of married women on welfare. We also report the results of a telephone survey of state AFDC agencies conducted to determine state rules governing cohabitation and marriage. The survey results indicate that, in a number of respects, AFDC rules encourage cohabitation. Finally, we conduct an analysis of the impact of AFDC rules on cohabitation, marriage, and single motherhood and find weak evidence in support of incentives to cohabit. 相似文献

In recent years, the lesbian and gay “scene” of bars, nightclubs, and dance parties has been undergoing a structural decline in many Western cities. This article aimed to examine the relevance of the scene to same-sex attracted young adults amid these changes. An online survey was conducted with 572 same-sex attracted young women and men in Sydney. Only a minority of respondents participated in the scene at least weekly (16%), and the majority did not regard the scene as important to their leisure time (60%). However, respondents valued the scene as a space to connect with other same-sex attracted people and display same-sex affection without fear of hostility. Lesbian and gay identified respondents tended to be more socially engaged with the scene compared to other same-sex attracted respondents. The findings suggest that while the scene continues to be valued by many same-sex attracted young people, improved social attitudes have made participating in the scene less of an imperative. 相似文献

Social background has historically been recognized as a major factor influencing family behavior, though recent work has largely emphasized racial/ethnic influences. Here we use 1994 – 1995 and 2001 – 2002 Add Health data to examine the cohabitation, first marriage, and first birth experience of young women. In a multistate life table context, hypothetical cohorts specified in terms of race and mother’s education are followed, from age 11 to age 24, as they move through 6 family‐related statuses. The results indicate that, for both Black and White women, a higher level of maternal education is generally associated with less cohabitation, less marriage, fewer first births, and a higher percentage of women who experience none of those transitions before age 24. Racial and social background differences are conceptually and empirically distinct. Because mother’s education is associated with substantially different trajectories of early family behavior for both Blacks and Whites, we argue that social background merits increased attention in research on contemporary American family patterns. 相似文献

We consider the fraction of pairs of m distinct alternatives on which a social welfare function f may be nondictatorially independent and Pareto when the domain of f satisfies the free k-tuple property. When k = 4 we improve the existing upper bound to . When there are at least 26 alternatives and we obtain an original upper bound, . To obtain these results we define and analyze the graph formed from the nondictatorial independent and Pareto pairs and
combine the results of this analysis with known results from extremal graph theory.
The authors extend special thanks to the two reviewers and the editor for their comments. 相似文献

Limited empirical study of the career development of Asian Americans in general and Korean Americans in particular has been conducted. The authors present the results of a theory‐based exploration of the career goals of Korean American university students in which ethnic identity, self‐efficacy, outcome expectations, and career interests were used to predict goal intentions for science and nonscience careers. Outcome expectations and career interests predicted a moderate amount of variance in science career goal intentions and a moderate to large amount of variance in nonscience career goal intentions. Korean American students' career goal development seems similar to that of American college students. 相似文献

This study examined the ways in which cultural orientation (communalism and material well‐being) and empathy influence the moral reasoning of African American middle to late adolescents. Specifically, this study utilized path analysis to investigate Ward's (1995) hypothesis that a communal orientation would promote morality among African American adolescents, while a material well‐being orientation would mitigate against it. In addition, it was hypothesized that empathy would mediate the relationship between cultural orientation and moral reasoning. Thirty‐seven high school students and 35 college students participated in the study. Results revealed that communalism was a significant predictor of empathy. Despite prediction, communalism and material well‐being were not predictors of moral reasoning. The findings did not yield support for empathy functioning as a mediator between communalism and moral reasoning. These findings are discussed in terms of previous findings, methodological limitations, and implications for future research. 相似文献
