The Diffusion of Tolerance: Birth Cohort Changes in the Effects of Education and Income on Political Tolerance 下载免费PDF全文
Political tolerance—the willingness to extend civil liberties to traditionally stigmatized groups—is pivotal to the functioning of democracy and the well‐being of members of stigmatized groups. Although political tolerance has traditionally been more common among American elites, we argue that as tolerance has increased, it has also diffused to less educated and less affluent segments of the population. The relative stability of political attitudes over the life course and the socialization of more recent birth cohorts in contexts of increased tolerance suggest that this diffusion of tolerance occurs across birth cohorts rather than time periods. Using age‐period‐cohort models and more than three and a half decades of repeated cross‐sectional survey data, we find persistent and robust across‐cohort declines in the importance of both income and higher education in determining levels of political tolerance. Declines in the effects of socioeconomic status are evident with tolerance toward all five out‐groups in the analysis—anti‐religionists, gays and lesbians, communists, militarists, and racists—but to varying degrees. These findings fit with a model of changes in public opinion, particularly views of civil and political rights, through processes of cultural diffusion and cohort replacement. 相似文献

Objective: The ways that college students cope with stress, particularly interpersonal stress, may be a critical factor in determining which students are at risk for impairing mental health disorders. Using a control-based model of coping, the present study examined associations between interpersonal stress, coping strategies, and symptoms. Participants: A total of 135 undergraduate students from 2 universities. Methods: Interpersonal stress, coping strategies, depression, anxiety, and somatization were assessed via self-report. Results: Students reporting more interpersonal stress reported more depression, anxiety, and somatization, and they reported less use of engagement coping strategies and greater use of disengagement coping strategies. Engagement coping strategies accounted for a significant portion of the association between interpersonal stress and mental health symptoms. Unexpectedly, coping strategies did not moderate the association between stress and mental health symptoms. Conclusion: Interventions designed to improve students' coping strategies may be an effective way to reduce mental health problems on college campuses. 相似文献

The study purpose was to develop and pilot an undue influence screening tool for California’s Adult Protective Services (APS) personnel based on the definition of undue influence enacted into California law January 1, 2014. Methods included four focus groups with APS providers (n = 33), piloting the preliminary tool by APS personnel (n = 15), and interviews with four elder abuse experts and two APS administrators. Social service literature—including existing undue influence models—was reviewed, as were existing screening and assessment tools. Using the information from these various sources, the California Undue Influence Screening Tool (CUIST) was developed. It can be applied to APS cases and potentially adapted for use by other professionals and for use in other states. Implementation of the tool into APS practice, policy, procedures, and training of personnel will depend on the initiative of APS management. Future work will need to address the reliability and validity of CUIST. 相似文献

Despite a number of studies investigating the effect of pharmacotherapy on treatment costs for schizophrenia patients, there has been little attention given to the effect of family intervention. In this study, data from the Kansas Medicaid system were used to analyze healthcare costs for 164 schizophrenia patients who had participated in family intervention. Structural equation modeling was used to test two competing views of the role of family intervention in treatment. The results showed that a model including direct and indirect effects of family intervention provided a better fit to the data. Family intervention had a significant indirect effect on general medical costs (through other psychological treatment) that showed a savings of $586 for each unit increase in the provision of these services. In addition, the total indirect effects for family intervention showed a $580 savings for general medical costs and $796 for hospitalization costs (for each unit increase). 相似文献

The critical path in a PERT/CPM network is determined in various textbooks by finding the path with associated minimal slack for the network arcs or by finding the path with associated minimal slack for the network nodes. This paper points out that the use of nodes can result in a network path being incorrectly identified as a path of maximum length. 相似文献

This field study provides variables that can be used by practitioners as action levers and by future researchers as the basis for theoretical development. Conclusions from relevant literature and findings from interviews with interdisciplinary research management identified forty variables that were viewed as important to interdisciplinary research project success. After adjusting the data for reliability attenuation, these variables were further analyzed to identify the best prediction equation. The findings suggested that project age or the longevity of the project and open discussion of disagreements were the best predictors of performance. 相似文献

Moving and union dissolution 总被引:1,自引:0,他引:1
This paper examines the effect of migration and residential mobility on union dissolution among married and cohabiting couples. Moving is a stressful life event, and a large, multidisciplinary literature has shown that family migration often benefits one partner (usually the man) more than the other Even so, no study to date has examined the possible impact of within-nation geographical mobility on union dissolution. We base our longitudinal analysis on retrospective event-history data from Austria. Our results show that couples who move frequently have a significantly higher risk of union dissolution, and we suggest a variety of mechanisms that may explain this. 相似文献

San Antonio, Texas, the seventh largest city in the United States, has experienced steady population growth, since the “boom”
of the 1960s. Projected water shortages due to this growth were realized as early as the 1970s by city leaders and south-central
Texas regional development decision makers. To reduce dependence on the already over-taxed, Edwards aquifer, a solution, the
Applewhite Dam and Reservoir Project, was developed with wide acceptance by federal, state, and city leaders who regarded
the project as a necessary measure for regional growth and development. However, opposition by taxpayer and environmental
groups led to referendums of 1991 and 1994 in which voters blocked construction of the dam and reservoir leaving the city
with limited options for water provision. This case study investigated the factors which led to a clear mismatch in communication
between decision makers—those who were aware of the actual and quantifiable risk to the region in terms of reduced water supplies—and
the general public, a population that did not have complete and/or adequate knowledge of their actual risk regarding future
water shortages, nor, of solutions being developed, such as the Applewhite project. The findings from this case study indicate
that when municipal leadership fails to adequately communicate risk regarding resource shortage to an affected public, as
well as, openly planned solutions, that voters are likely to underestimate future impacts of water shortages, heed last-minute
opposition, and reject long-standing, publicly proposed projects. The intent of this research is not to support either side
in the Applewhite controversy, but to shed perspective on the process of adequately and effectively communicating future water
needs to an at-risk population. Decision makers in cities across the United States who are faced with solving problems of
limited resources needed by a large populace may be informed by the results of this research. 相似文献
