We use data from the National Longitudinal Survey of Adolescent Health to estimate effects of adolescent girls' overweight on their propensity to engage in risky sexual behavior. We estimate single equation, two‐stage, and sibling fixed‐effects models. We consider both absolute weight and weight relative to other girls in the individual's school. We focus on vaginal intercourse without a condom, any type of sexual activity while under the influence of alcohol, and anal intercourse. Our findings confirm previous research indicating that overweight or obese girls are less likely than their recommended‐weight counterparts to be sexually active. As a result, they are less likely to have vaginal intercourse without a condom. However, overweight or obese girls are not less likely to have sex under the influence of alcohol, and once they have had vaginal intercourse, their consistency of condom use is no different from that of their recommended‐weight peers. The most striking finding is that overweight or obese girls are at least 15% more likely than their recommended‐weight peers to have ever had anal intercourse regardless of whether they have ever had vaginal sexual intercourse. The results from this study underscore the importance of using multifaceted and contemporary measures of risky sexual behavior and have implications for the health and well‐being of adolescent girls.

Data from a nationwide opinion survey are used to test the propositionthat President Reagan's sponsorship of the INF treaty effectivelydisarmed the opposition that hard-liners would normally haveregistered against the treaty. The data are consistent withthis interpretation. That is, the president's endorsement ofthe treaty had only a modest impact on those who perceived theSoviets as relatively nonthreatening, but it had a much morepronounced impact on those who viewed the Soviets as threatening.These results shed new light on the extent to which and theconditions under which Americans are willing to set aside theirown policy predilections and follow along behind presidentialinitiatives in the international arena.  相似文献

Correspondence to Carole Smith, School of Social Work,, Department of Social Policy and Social Work, Dover Street Building, The University of Manchester, Oxford Road, Manchester M13 9PL Summary In their contributions to the debate about social work, modernityand postmodernity Parton(1994) and Howe (1994) argue that therecent changes in social work practice can best be understoodas features of, or responses to, the postmodern social orderin which it is located. This has led, they argue, to an increasingfragmentation of the profession and an undermining of its formalknowledge base. We will argue here that, not only does suchan argument oversimplify the nuances of the ‘postmodernity’question, but it represents a misreading of the pressures affectingpractice at this time, which are more properly attributableto the operation of the discourses and ideologies of a particularphase of late capitalism and high modernity.  相似文献

Correspondence to Susan White, University of Manchester, Department of Social Policy and Social Work, Williamson Building, Oxford Road, Manchester Summary Over the last three decades qualitative research methodologieshave been in the ascent within social science. Yet social workevaluation studies have tended to be quantitative in nature,conventially relying upon the generation of criteria againstwhich interventions are retrospectively judged. The generationof such criteria inevitably depends upon pre-suppositions, whichin themselves go unresearched. As a consequence the .sense makingactivities on which social work interventions depend are renderedimmune from critical analysis. This reflects a broader tendencyfor social work to cling to naive realist epistemologies, whichare arguably obsolete within the interpretive paradigm in whichits activity is properly located. By examining the debates withininterpretive social science, this paper argues for an approachto social work assessment which avoids the pitfalls of naiveobjectivism and the nihilism of anarchic relativism, whilstretaining creativity, imagination and hope.  相似文献

The authors report on a study of student attitudes towards disabled students in three colleges of further education. They found that many non-disabled students were not aware of the various issues facing disabled students at the colleges. Social contact between disabled and non-disabled students was not extensive, although those who had attended school with disabled pupils were more likely to have friendships with disabled students at college. Whilst non-disabled students were strongly supportive of inclusive education in principle, many saw inclusion in the mainstream as conditional on the particular impairment of an individual. Disabled and non-disabled students supported the view that early social and educational contact results in greater mutual understanding, and is of benefit to all students.  相似文献

In this paper we explore the nature and causes of individualdifferences in the use of feeling thermometer items to evaluatesocial groups. Some respondents have a general tendency to assignhigher overall temperature readings and some tend to use a widerrange of the temperature scale. These tendencies are partiallyunderstandable in terms of the respondent's evaluations of socialgroups, but other important predictors are identified. Methodsof adjusting feeling thermometer scores to account for individualdifferences are explored, using data from the 1984 AmericanNational Election Study. The conclusion is that some sort ofadjustment is probably useful for those studying supportersof conservative groups, though such a procedure may not be neededfor those who focus on liberal groups.  相似文献
