Health care has been a contentious issue in American politics for decades, and scholars are beginning to understand the reasons behind public support for, and opposition to, healthcare reform. Using national survey data, we measure the impact of various racial attitudes, including Racial Resentment and Ethnocentrism, on white support for healthcare reform. We measure participants’ attitudes across a range of important dimensions of healthcare reform and examine a randomized experiment with a control group that frames legislation as “recent” healthcare reform and a treatment condition that frames legislation as “President Obama’s” healthcare reform. The findings demonstrate that racial attitudes and Ethnocentrism continue to play a role in both support and opposition to healthcare reform.  相似文献

Gaze patterns to figure images have been proposed to reflect the observer's sexual interest, particularly for men. This eye-tracking study investigated how individual differences in sexual motivation tendencies are manifested in naturalistic gaze patterns. Heterosexual men and women (M = 21.0 years, SD = 2.1) free-viewed plain-clothed male and female figures, aged 10, 20, and 40 years old, while their eye movements were recorded. Questionnaires were used to measure sexual cognitions, including sensation seeking and sexual compulsivity, sexual inhibition and excitation, and approach and avoidance responses to sexual stimuli. Our analysis showed a clear role of sexual cognitions in influencing gaze strategies for men. Specifically, men who scored higher on sexual compulsivity dedicated more gaze to the waist–hip region when viewing figures of their preferred sexual partners than men who scored lower on sexual compulsivity. Women's sexual cognitions showed no clear effect on the gaze pattern in viewing figures of their preferred age and gender of sexual partners, suggesting women's gaze is unlikely to be a straightforward reflection of their sexual preferences. The findings further suggest that men's gaze allocation is driven by sexual preferences and supports the utility of eye tracking in the assessment of male sexual interest.  相似文献

The purpose of this study was to examine male sex workers' awareness of the social stigma surrounding involvement in the sex industry and the possible effects of that stigma. Personal interviews were conducted with 21 men (9 independent escorts who advertised via the Internet and 12 escorts/erotic masseurs who were on contract with an agency). Results indicated that a majority of interviewees believed sex work was stigmatized but attributed this stigma to society's tendency to conflate escort/erotic masseur with street-based prostitute and society's negative view of human sexuality in general and homosexuality in particular. It should be noted that interviewees did not necessarily perceive the gay community as more tolerant than the heterosexual community of persons involved in the male sex industry. In terms of how participants saw the sex trade, both prior to and during their involvement, multifarious viewpoints emerged (i.e., some engaged in "whore mythologizing" while others reported having no clearly defined perception of male sex workers). Finally, results suggested that some participants believed their involvement in a stigmatized industry was deleterious to them personally whereas others maintained that the consequences of being an escort/ erotic masseur were largely positive.  相似文献

Because conditional cash transfer (CCT) programmes (which make payments to poor households, conditional on their behaviour) potentially affect both household resource levels and parental preferences for quality vs. quantity of children, they may have unintended consequences for fertility. We use panel data from experimental CCT programmes in three Latin American countries to assess the unintended impact of these programmes on childbearing. Our findings, based on difference-in-difference models, show that the programme in Honduras, which inadvertently created large incentives for childbearing, may have raised fertility by between 2 and 4 percentage points. The CCT programmes in the two other countries, Mexico and Nicaragua, did not have the same unintended incentives for childbearing, and in these countries we found no net impact on fertility. Subsequent analysis examined several potential mechanisms by which fertility in Honduras may have been raised but was not able to identify a primary mechanism with the available data.  相似文献

Root zones of mature Sweetgum paved with either pervious or impervious concrete after 15–18 years of tree growth exhibited much reduced standing fine root length compared to unpaved plots 3 years after pavement installation. The objective of this paper was to determine whether these observed reductions in standing root length were due to reduced root production rates or due to enhanced root mortality rates in response to the presence of either pavement. We measured both fine root production and root death over a 15-month period using biweekly nondestructive observations of the root zones at four depths. In addition, we used proportional hazards analysis to determine how the presence of pavement affected chances of root mortality. We found that new root production was more negatively affected by the presence of either pavement than root mortality while chances of root mortality were increased by the presence of pavement, leading to much reduced standing net root length in paved plots at any given time. Surprisingly, even though root production and mortality were strongly altered by pavement, there was no significant effect on tree diameter growth. These results suggest that while Sweetgum root dynamics are negatively affected by pavement, there is enough plasticity within this species to adapt to altered root zone dynamics without affecting aboveground growth.  相似文献

Stepfamilies are an increasingly common context in which adults and children reside. Past research has examined family processes that promote family resilience, such as dyadic relationships marked by warmth, positive communication, satisfaction, and closeness. What remains less clear is whether various profiles of dyadic relationship quality within stepfamilies exist and operate to influence stepfamily stability. Using data from the National Longitudinal Study of Adolescent to Adult Health, we conducted a latent profile analysis of mother–child, stepfather–child, and stepcouple relationship quality among a sample of 1,646 adolescents residing in married and cohabiting mother–stepfather families. Results favor a 4-profile solution, labeled high-quality, high-quality couple relationship, high-quality parent–child relationships, and low-quality. The identified latent profiles displayed differences with respect to family stability, or rates of remaining an intact family system 1 year later.  相似文献

Abstract

In this Standards Update column, Todd Carpenter, Executive Director of the National Information Standards Organization (NISO), provides a preview of NISO’s upcoming RA21 Recommended Practice for single sign-on systems. Carpenter describes previous attempts at single sign-on standards, the essential difficulties in authenticating users, and how RA21 will address these issues while ensuring the privacy of user data.  相似文献

The purpose of this study is to examine how organizational resources affect the gender gap within lay (volunteer) leadership in religious congregations. Using institutional theory as a framework, this study situates congregations within a larger field of organizations competing for legitimacy. Congregations with higher levels of resources—such as wealthier members, better-educated members, or larger memberships—are more likely to be connected to the core of the field and therefore more likely to have gender egalitarian practices in order to signal their legitimacy. Therefore, I hypothesize that women in resource-rich congregations will have greater access to volunteer leadership positions than women in congregations that are resource deficient. I analyze 70,942 individuals in 344 religious congregations from the 2001 U.S. Congregational Life Survey using multilevel modeling. I show that religious congregations with more members, better-educated attenders, and wealthier attenders have smaller gender gaps in volunteer leadership positions. Congregational resources can mitigate the gender gap in lay leadership, and women within resource-rich organizations have greater access to positions of authority.  相似文献

While it is often argued that a p-value is a probability; see Wasserstein and Lazar, we argue that a p-value is not defined as a probability. A p-value is a bijection of the sufficient statistic for a given test which maps to the same scale as the Type I error probability. As such, the use of p-values in a test should be no more a source of controversy than the use of a sufficient statistic. It is demonstrated that there is, in fact, no ambiguity about what a p-value is, contrary to what has been claimed in recent public debates in the applied statistics community. We give a simple example to illustrate that rejecting the use of p-values in testing for a normal mean parameter is conceptually no different from rejecting the use of a sample mean. The p-value is innocent; the problem arises from its misuse and misinterpretation. The way that p-values have been informally defined and interpreted appears to have led to tremendous confusion and controversy regarding their place in statistical analysis.  相似文献
