Prior research has reported that many Americans hold prejudicial attitudes toward sexual and gender minorities. Most of this research analyzed attitudes toward target categories in isolation and not in relation to attitudes toward heterosexuals. In addition, most previous research has not examined attitudes of members of sexual and gender minority categories toward other categories. While some research has examined the influence of religiosity on attitudes toward sexual and gender minorities, none of these studies has examined religiosity while also examining the influence of spirituality. In this article we drew on insights from queer theory to examine attitudes toward heterosexual, gay, lesbian, bisexual, and transgender individuals, as well as individuals who practice polygamy, among college students. Three samples gathered over a four-year period (2009, 2011, 2013) at a private, nonsectarian, midsized urban university in the Southeastern United States were used. We found that heterosexuals had the most positive rating, followed in order of rating by gay/lesbian, bisexual, and transgender individuals, and then those who practice polygamy. Regression analyses revealed gender and race were significant predictors of attitudes toward various sexual and gender categories. Holding a literalistic view of the Bible and self-identifying as more religious were related to more negative views toward sexual minorities, while self-identifying as more spiritual was related to more positive views. 相似文献

In a large longitudinal study involving young adults, we conducted an eight-hour STD educational intervention and examined the impact of the intervention on the efficacy of a message for promoting condom use. The message was framed in positive or negative terms and was presented visually or in numbers (percentages or frequencies). Results indicated that the numerical positive-framed message increased condom use among young adults who did not receive the intervention, whereas the numerical negative-framed message did not. Attitudes toward condom use along with changes in intentions to use condoms mediated this framing effect. In contrast, the positive-framed and negative-framed messages were equally and highly effective for promoting condom use when the messages were presented visually or when young adults received the STD educational intervention before reading the message, suggesting that the simple brochures featuring visual aids were as effective in changing attitudes and behavioral intentions as the extensive intervention. These findings add to a growing body of evidence detailing the mechanisms that allow well-constructed visual aids to be among the most effective, transparent, memorable, and ethically desirable means of risk communication. Clinical and public health implications are discussed. 相似文献

Drawing from the life course perspective, racial disparities in hospitalization are considered in light of a chain of risk. We ask whether race influences admission to, length of stay in, and mortality following hospitalization. Analyses address these questions with data from a national longitudinal sample of adults to assess racial disparities in the hospitalization experience (n = 6,833). Survey data were merged with hospital records abstracted over 20 years of observation. Multivariate analyses revealed that there were no racial differences in admission, but that black adults generally had longer stays. When isolating each stay prospectively, black adults had longer stays during the first, third, and fourth hospitalizations. Post-hospital mortality after the first stay was also higher for black adults than for their white counterparts, even after controlling for morbidity and status resources. The findings suggest that the racial disparities in hospital length of stay and mortality are explained by the cumulative effects of social and health inequalities over the life course. 相似文献

Cue reactivity, while increasingly recognized as a central feature of drug and alcohol addiction, is not well studied in gambling.
We evaluated the urge to gamble in a simulated casino environment among frequent gamblers who alternated between cycles in
which they observed others playing ten hands of Blackjack (first, third and fifth cycle) and cycles in which they played ten
hands of Blackjack themselves (second and fourth cycle). The played cycles served as a manipulation for the observed cycles
in terms of “priming” (having previously gambled in the environment vs. not) and “anticipation” (expecting more opportunities
to gamble in the environment vs. not) and, thus, allowed these conditions: observed cycle 1 = anticipation (+) and prime (−); observed cycle 2 = anticipation (+) and prime (+); and observed cycle 3 = anticipation (−) and prime (+). Subjects’ urge to gamble was greater in the gambling environment than in a neutral setting
and both positive anticipation and positive priming increased cue reactivity within the gambling environment. The frequency
of gambling outside of the study did not affect cue reactivity. However, a preference for Blackjack (vs. other types of gambling)
and observing winning (vs. losing) hands were both associated with stronger cue reactivity in the study. These findings contribute
to our understanding of pathological gambling. 相似文献

This study examines and further develops the classic Strehler-Mildvan (SM) general theory of mortality and aging. Three predictions
from the SM theory are tested by examining the age dependence of mortality patterns for 42 countries (including developed
and developing countries) over the period 1955–2003. By applying finite mixture regression models, principal component analysis,
and random-effects panel regression models, we find that (1) the negative correlation between the initial adulthood mortality
rate and the rate of increase in mortality with age derived in the SM theory exists but is not constant; (2) within the SM
framework, the implied age of expected zero vitality (expected maximum survival age) also is variable over time; (3) longevity
trajectories are not homogeneous among the countries; (4) Central American and Southeast Asian countries have higher expected
age of zero vitality than other countries in spite of relatively disadvantageous national ecological systems; (5) within the
group of Central American and Southeast Asian countries, a more disadvantageous national ecological system is associated with
a higher expected age of zero vitality; and (6) larger agricultural and food productivities, higher labor participation rates,
higher percentages of population living in urban areas, and larger GDP per capita and GDP per unit of energy use are important
beneficial national ecological system factors that can promote survival. These findings indicate that the SM theory needs
to be generalized to incorporate heterogeneity among human populations. 相似文献

Although a homophobic and sexist archetype of heterosexual masculinity has been thought to permeate competitive teamsport, matters have been rapidly changing. This is evident in research on openly gay athletes, attitudes among heterosexual athletes, and recent studies on decreasing homophobia among sport media content. In this research, however, we examine how some men still adhere to a homophobic and sexist masculine deposition when discussing sport on the Internet. A textual analysis was used to analyze hegemonic masculinity from a popular American football message board. Although posts related to hegemonic masculinity did not permeate the data, we found that this traditional form of masculinity was upheld through misogyny, homophobia, and the objectification of women. Thus, whereas mainstream sport media is increasingly policed for homophobia and sexism, this research shows that the anonymity of the Internet permits hegemonic masculinity to flourish in specific locations, without contestation. 相似文献

With a focus on the United States, this paper addresses the basic social indicators question: How are we doing? More specifically, with respect to children, how are our kids (including adolescents and youths) doing? These questions can be addressed by comparisons: (1) to past historical values, (2) to other contemporaneous units (e.g., comparisons among subpopulations, states, regions, countries), or (3) to goals or other externally established standards. The Child and Youth Well-Being Index (CWI), which we have developed over the past decade, uses all three of these points of comparison. The CWI is a composite index based on 28 social indicator time series of various aspects of the well-being of children and youth in American society that date back to 1975, which is used as a base year for measuring changes (improvements or deterioration) in subsequent years. The CWI is evidence-based not only in the sense that it uses time series of empirical data for its construction, but also because the 28 indicators are grouped into seven domains of well-being or areas of social life that have been found to define the conceptual space of the quality of life in numerous studies of subjective well-being. Findings from research using the CWI reported in the paper include: (1) trends in child and youth well-being in the United States over time, (2) international comparisons, and (3) best-practice analyses. 相似文献

This study applies latent trajectory methods to the analysis of temporal changes in homicide rates among large US cities across recent decades. Specifically, annual homicide rates for 157 large US cities are analyzed for the 30 years from 1976 to 2005. We address the fundamental questions: Did all of cities experience similar levels and patterns of rise and decline in homicide rates over these three decades? Or is there hidden or unobserved heterogeneity with respect to these temporal patterns, thus leading to the identification of more homogeneous groupings of the cities? And if latent homogeneous groupings surface, is membership due to specific structural characteristics found within those cities? Evidence is found for the existence of four latent homicide rate trajectories. After identifying and classifying the cities into these four groups, multivariate statistical techniques are used to determine which social and economic characteristics are significant predictors of these distinct homicide trends. Criminal justice measures are also included as controls. It is found that larger cities located in the South with higher levels of resource deprivation/concentrated poverty, higher income inequality, higher percentages of the adult male population that are divorced, higher unemployment rates, higher percentages of youth, higher percentages of the population who are Hispanic and higher numbers of police per capita are more likely to be in a higher than a lower homicide trajectory group. Higher percentages of the population enrolled in colleges and universities and locations in states with higher incarceration rates are characteristics of cities associated with membership in a lower homicide trajectory group. 相似文献
