Perceived social support has long been recognized as associated with better health and longevity. However, important factors that may moderate this relationship have not been sufficiently explored. The authors used meta-analyses and meta-regressions to examine 178 all-cause mortality risk estimates from 50 publications, providing data on more than 100,000 persons. The mean hazard ratio (HR) for mortality among those with lower levels of perceived social support was 1.11 (95% confidence interval [CI]: 1.05, 1.17) among multivariate-adjusted HRs. Meta-regressions suggest that support from family members was more beneficial than support provided by friends, and that a moderate level of support may be enough to achieve positive results. The results also show that the importance of having support increases with age. No substantial difference was found between men and women with respect to the relationship between support and mortality.  相似文献

The collective display of particular symbols represents an emergent form of social movement participation. This study documents the patterns of the collective display of one such symbol; the magnetic war‐related ribbon (WRR). Using bivariate and multivariate analyses of a sample of 8,100 vehicles, we studied the relationships between WRR display and measures of political affiliation, patriotism, and war support. The results find that that WRR display is positively associated with affiliation with George W. Bush and the Republican Party, and various displays of patriotism and war support. This study demonstrates how advents in communication technologies, shifts in the social, economic, and political structures have converged and given rise to a new form of symbolic participation marked by the collective display of cause‐related symbols.  相似文献

During the pre-confirmation debate over Supreme Court Justice Sonia Sotomayor, critics accused her of allowing her background to influence her judicial decisions. This article assesses the validity of such a claim for all sitting justices from 1875 to 2007 in one relevant policy area, immigration. In this article, we look at all 185 immigration-related decisions by the Supreme Court from its creation through 2007. Logistic general estimating equation regression analysis of Supreme Court voting on these cases suggests that justices who were nominated by Democratic presidents, who were urbanites, and who had previous judicial experience were more likely to vote in favor of immigration. However, justices who grew up in the Southwest, had Southern European ancestors, or were ideological conservatives were more hostile to immigration. Although public opinion, the unemployment rate, and the percent foreign-born in a given year did not affect justices’ votes, non-asylum cases and appeals from the Eighth Circuit were more likely to receive favorable treatment. The mean level of racial liberalism of the Senators in office during a particular justice’s confirmation hearings likewise had a large impact on his or her subsequent rulings. These findings suggest that Supreme Court voting on immigration is substantially influenced by justices’ background and political preferences as well as by some political and legal structures. These results thus support Legal Realism and New Institutionalism instead of the Traditional Legal Model of Supreme Court behavior.  相似文献

Interdisciplinary doctoral education is being strongly encouraged by government agencies (e.g., the National Science Foundation and the National Institutes of Health) and universities. This position is predicated on the idea that integrating the perspectives of different disciplines is necessary for developing meaningful answers to complicated social problems. The purpose of this brief teaching note is to describe the development of a new interdisciplinary PhD program at Tulane University. The program is called City, Community & Culture, and it confers degrees in social work, sociology, and urban studies.  相似文献

“Don't Ask, Don't Tell” was devised to combat the perceived costs associated with gays and lesbians openly serving in the military, including low unit cohesion, damage to the military's reputation, and the general population's lack of acceptance for homosexuals serving (Belkin, 2008). However, recent polls and policy reversal have shown growing public support for homosexuals being allowed to serve openly. Interestingly, the amount of support has varied as a function of question wording. Two polls conducted by CBS News found support for homosexuals serving in the military varied with greater support for “gays and lesbians” compared to “homosexuals.” Two studies were conducted to further examine the effect of terminology on reported support. Two samples reported opinions for homosexual civil rights issues. Sexual orientation was described using the terms gay men and lesbians, homosexuals, gay men, or lesbians. Percentage differences were found to be greater than those reported in the CBS polls, as wording choice had an effect on reported openness regarding homosexual civil rights. These differences indicate that it is important to consider precise terminology usage when measuring opinions. Levels of support, stereotypes activated, and the relationship between support for civil rights and general levels of prejudice were examined.  相似文献

The 1998 U.S. Environmental Protection Agency Office of Pesticide Programs (OPP) re-registration eligibility decision (RED) for phosphine fumigants has generated much interest in defining safe levels of exposure for workers and worker bystanders. This report summarizes the pertinent literature on phosphine toxicity, including animal inhalation studies and human epidemiology studies, and also describes a margin-of-exposure (MOE) analysis based on available worker exposure data. In addition, a safe occupational exposure limit is estimated using typical OPP assumptions, after determination of appropriate uncertainty factors, based on quality of data in the principal study and pharmacokinetic considerations. While a conservative 8-hour time-weighted average (TWA) of 0.1 ppm was calculated, the overall weight of evidence, from a risk-management perspective, supports a conclusion that an occupational TWA of 0.3 ppm provides adequate health protection. In addition, a 15-minute short-term exposure limit (STEL) of 3 ppm was estimated. Finally, in contrast to the MOE analysis described in the OPP's phosphine RED, the MOE analysis described herein does not indicate that fumigation workers are currently being exposed to unacceptable levels of phosphine. Collectively, these findings support the occupational exposure limits of 0.3 ppm (8-hour TWA) and 1 ppm (STEL) established in the updated applicator's manuals for phosphine-generating products, which recently received approval from OPP.  相似文献

This study examined whether a comprehensive set of psychosocial factors was equally predictive of both adolescent vaginal intercourse and oral sex among 1,105 adolescents aged 12–16. Logistic regressions were used to examine the relationships between parental communication, religiosity, bonding to school, heavy drinking, sex expectancies, normative beliefs, and both oral sex and vaginal intercourse. Age, gender, bonding to school, heavy drinking, and negative health expectancies predicted both oral sex and vaginal intercourse. Parental communication was associated with vaginal intercourse but not oral sex. Behavior‐specific normative beliefs were differentially associated with oral and vaginal sex.  相似文献

Summary A comparison of perceptions of situations of child maltreatmentby parents in a low income deprived neighbourhood and a middleincome neighbourhood has been the subject of a study conductedin Israel. The findings of the research, in which 110 familieswere interviewed, indicated that what differed between thesesamples was not only the beliefs regarding effective and appropriatechild-rearing practices but also the rationale behind thesebeliefs. The findings also indicated that parental practicescould be considered as maltreatment in one socio-ecologicalcontext and not in another. Parents in the low income deprivedneighbourhood emphasized the risk in their neighbourhood asthe rationale for monitoring and controlling their children'sbehaviour. In the middle income neighbourhood, parents believedthey could use less restrictive methods in their child-rearingpractices. The need to consider the adaptive nature of parentingbehaviours within their socio-ecological context when assessingand intervening in situations of child maltreatment is discussed.  相似文献

In 1956, Bateson, Jackson, Haley, and Weakland published ‘Toward a Theory of Schizophrenia’. This paper was an early milestone in family therapy's development, signifying the importance that communications theory and cybernetics would hold for the evolution of the field over the ensuing three decades. Many are familiar with the notion of the double bind; however, the idea's theoretical underpinnings, and the broader contributions of the paper that launched it, are often misunderstood or overlooked. The 50th anniversary of the publication of ‘Toward a Theory of Schizophrenia’ offers an opportunity to revisit the importance of the contribution made by Bateson and his then colleagues, and to return to the fore the notions of logical typing, context, relationship and circularity that are at its heart.  相似文献
