Objectives. This study examines the factors that shape public acceptance of homosexuality and support for same-sex marriage across age cohorts.Methods. We analyzed data from two national surveys. We constructed hierarchical logistic and hierarchical ordinary least squares regressions for relevant age cohorts in order to test our hypotheses and explore our research questions.Results. Our models suggest that personal contact has a greater impact on the attitudes of younger respondents, positively influencing public acceptance of homosexuality. Alternatively, religious and ideological predispositions have a greater impact on the attitudes of older individuals. When examining public support for gay marriage, we find that younger individuals have higher levels of deliberative engagement with the issue debate, while older individuals rely more heavily on their predispositions when determining issue stance. Interestingly, measures of media exposure are not significantly related to either public acceptance of homosexuality or support for same-sex marriage, suggesting that other factors may have a greater impact on public attitudes at this point in time.Conclusion. The implications of these findings are discussed in light of the emergence of a new political generation and the continuing struggle for gay civil rights.  相似文献

In a call center, staffing decisions must be made before the call arrival rate is known with certainty. Once the arrival rate becomes known, the call center may be over‐staffed, in which case staff are being paid to be idle, or under‐staffed, in which case many callers hang‐up in the face of long wait times. Firms that have chosen to keep their call center operations in‐house can mitigate this problem by co‐sourcing; that is, by sometimes outsourcing calls. Then, the required staffing N depends on how the firm chooses which calls to outsource in real time, after the arrival rate realizes and the call center operates as a M/M/N + M queue with an outsourcing option. Our objective is to find a joint policy for staffing and call outsourcing that minimizes the long‐run average cost of this two‐stage stochastic program when there is a linear staffing cost per unit time and linear costs associated with abandonments and outsourcing. We propose a policy that uses a square‐root safety staffing rule, and outsources calls in accordance with a threshold rule that characterizes when the system is “too crowded.” Analytically, we establish that our proposed policy is asymptotically optimal, as the mean arrival rate becomes large, when the level of uncertainty in the arrival rate is of the same order as the inherent system fluctuations in the number of waiting customers for a known arrival rate. Through an extensive numerical study, we establish that our policy is extremely robust. In particular, our policy performs remarkably well over a wide range of parameters, and far beyond where it is proved to be asymptotically optimal.  相似文献

Youth development professionals and parks and recreation professionals often are charged with providing services to youth. However, the approach of each can be quite different as recreation is a primary focus for recreation professionals and part of many services offered by youth development specialists. Despite the differences, these two groups of professionals can learn a great deal from each other. This article examines youth development and staff training with examples from the field and suggests how youth development professionals can learn from recreation professionals and vice versa. It suggests that parks and recreation professionals can strengthen degree programs, accreditation, certification, and continuing education by incorporating specific youth development competencies established by the National Collaboration for Youth. For their part, youth development professionals can learn from parks and recreation professionals how to enhance recreation programming as part of their services by gaining an understanding of program design, program and activity leadership, and administrative practices. With much debate over whether more education or more experience is a better path for those working with youth, the authors suggest that a combination of both will adhere to the quality of staff. Staff gain further knowledge and skill from academic preparation at the undergraduate and graduate levels, field-based training through jobs and internships, and continuing education courses specializing in youth development competencies and recreation-based competencies set within a youth development environment.  相似文献

Research traditionally has focused on the development of symptoms in those who experienced trauma directly but overlooked the impact of trauma on the families of victims. In recent years, researchers and clinicians have begun to examine how individual exposure to traumatic events affects the spouses/partners, children, and professional helpers of trauma survivors. The current study reports data from a larger mixed-methodology study that includes qualitative interview data from 17 individuals, coded to identify the mechanisms that may affect the couple's interpersonal functioning when there is a history of trauma exposure in one or both partners. The following primary themes were identified: role in the relationship, boundary issues, intimacy problems, triggers, and coping mechanisms. Areas for future research and clinical implications also are identified.  相似文献

This article examines public performances of mothering children with intellectual disabilities through thematic discourse analysis of thirty‐three published memoirs. These data reveal presentations of self that, once consumed and interpreted by public interaction, emerge collectively as a “warrior‐hero” identity, a reformulated archetype in the social construction of a good mother. This archetype places a cultural expectation on mothers to do battle to attain resources and possible cures for their children, ultimately shifting the historical burden on mothers from causing the intellectual disabilities of their children to curing them. The article concludes with a discussion of how this hyperfocus on expert parenting has the potential to leave mothers of children with intellectual disabilities strained and subject to the pitfalls of systems of inequality.  相似文献

This study uses administrative data from Michigan State University to examine whether students who are former foster youth are more likely to drop out of college than low-income, first generation students who had not been in foster care. Former foster youth were significantly more likely to drop out before the end of their first year (21% vs. 13%) and prior to degree completion (34% vs. 18%) than their non-foster care peers. This difference remained significant even after controlling for gender and race.  相似文献

ABSTRACT

Although there is extensive scholarship that examines differences in family behaviors and attitudes between whites and blacks, there are very few studies that examine these differences across whites, blacks, Latinos, and Asians in the United States. In the current study, we do so by examining data from the 2011 Houston Area Survey. We explore Houstonians’ likelihood of engaging in interracial relationships, attitudes toward working mothers, and attitudes toward same-sex marriage. Houston was selected as the target of the study given its rise as the most racially and ethnically diverse metropolitan area in the nation. Non-white Houstonians are more likely to date members of other racial/ethnic groups. With regard to attitudes toward working mothers, only Latino and Asian immigrants hold less accepting views than whites. Finally, the results with regard to same-sex marriage equality suggest that increased migration and diversity within Houston could hasten social change and acceptance.  相似文献

Analyzing interview data from 33 women and men, we examine how perceptions of sexual harassment are linked to age, experience, and historical context. Participants described workplace experiences from adolescence into their late twenties. Three themes emerged. First, as adolescents, respondents perceived some of the sexualized interactions they experienced at work as fun. Second, while participants did not define some of their early experiences as sexual harassment at the time, they do so today. Finally, participants suggested that prior work experiences changed their ideas about workplace interactions and themselves as workers. In sum, we find age is a fundamental dimension of power shaping individuals’ perceptions of sexualized interactions at work.  相似文献

The ethical delivery of social work education is guided by academic and professional codes of conduct, though often these documents fail to explicitly address the array of dilemmas faced by faculty and administrators. This paper examines commonly occurring ethical dilemmas faced by social work educators in carrying out their roles of teaching, scholarship and service. Specifically, the codes of professional social work organizations from four nations, the American Association of University Professors, the International Federation of Social Workers and the Codes of Conduct and Practice from the General Social Care Council in England are applied to four vignettes for analysis and discussion. Recommendations are offered for discerning relevant guidelines to resolve the unique dilemmas experienced by social work educators and consideration is given to the development of a specialized code for social work educators.  相似文献

Abstract

Objective: The purpose of this study was to determine whether student awareness and attitudes about organic foods would predict their behaviors with regard to organic food consumption and other healthy lifestyle practices. A secondary purpose was to determine whether attitudes about similar eco-friendly practices would result in socially conscious behaviors. Participants: The sample was students (N = 443) enrolled in 1 of 2 core courses in a mid-sized Southern university. Method Summary: Students completed an anonymous 28-item survey about their awareness, attitudes, and behaviors. Linear regression and path analysis were used to test whether attitudes were related to purchase of organic foods and eco-friendly behaviors. Results: Many students (49%) possessed factual knowledge about organic foods. More (64%) felt positively about having organic food options available to them both on campus and elsewhere. Taste and price most influenced the purchase of such foods. Attitudes were significant predictors of consumption behaviors and healthy practices. Conclusions: Positive attitudes toward organic foods and other environmentally friendly practices significantly predicted similar behaviors. Student consumers seem to act upon their beliefs.  相似文献
