The purpose of this investigation was to understand how "fag hags" and gay-supportive heterosexual men (GSHM) describe the nature and quality of their interpersonal contact experiences with gay men. Eight archival interviews were analyzed using the methodologies outlined in Hill, Thompson, and Williams (1997); i.e., consensual qualitative research. The results yielded suggest that the nature of contact experiences relates to direct contact with gay men in institutional or social settings or via indirect, formative experiences. The possible roles that contact plays in attitudes formation include: (1) normalizing homosexuality, (2) challenging previously held myths and stereotypes, and (3) increasing a person's likelihood of having contact experiences with gay men and developing gay-supportive attitudes. Participants described the quality of the contact as taking place in the context of a friendship that developed between them and a gay male that strengthened after the gay friend came out. Furthermore, the impact of these contact experiences did not change fag hags' sense of morality, but "improved" their attitudes toward gay men. The results from this study have broader social implications in that they contribute to the much-needed discourse, from a qualitative perspective, on the ways in which people form gay-supportive attitudes. Future research should focus on describing the transformational nature of contact between gay men and heterosexuals in order to uncover any processes or stages that heterosexuals go through in developing gay-supportive attitudes. 相似文献

Children in foster care face poverty, family dysfunction, neglect, and abuse, with high rates of chronic health, emotional, and developmental problems. This study compared the overall health status of a group of children entering foster care with a group of Medicaid-eligible children living with their parents, matched for age and gender. It identified significantly more health and developmental problems in children in foster care than in the comparison group. Possible contributors to the higher percentage of problems among foster care children may be that the foster children have more problems related to the underlying risk factors resulting in placement, or that the foster care physicians conducted a more comprehensive assessment or had lower clinical thresholds. Further research is necessary to identify and treat the problems of this high-risk group. 相似文献

For the past several years the author and his colleagues have explored the area of how social psychological constructs and theoretical models can be applied to the prevention of health threatening behaviors in adolescents. In examining the need for the development of gambling prevention programs for adolescents, it might be of value to consider the application of such constructs and theoretical models as a foundation to the development of prevention programs in this emerging problem behavior among adolescents. In order to provide perspective to the reader, the present paper reviews the history of various psychosocial models and constructs generic to programs directed at prevention of substance abuse in adolescents. A brief history of some of these models, possibly most applicable to gambling prevention programs, are presented. Social inoculation, reasoned action, planned behavior, and problem behavior theory, are among those discussed. Some deficits of these models, are also articulated. How such models may have relevance to developing programs for prevention of problem gambling in adolescents is also discussed. However, the inherent differences between gambling and more directly health threatening behaviors such as substance abuse must, of course, be seriously considered in utilizing such models. Most current gambling prevention programs have seldom been guided by theoretical models. Developers of gambling prevention programs should consider theoretical foundations, particularly since such foundations not only provide a guide for programs, but may become critical tools in evaluating their effectiveness. 相似文献

The author is an investment analyst whose area of specialization is financial shares, especially in banking. The prime responsibility of the investment analyst is to the investment institutions. However, the information available to the analyst is no more than that available to shareholders in the institution being monitored. The expertise of the analyst is in seeking out the information and interpreting it for the client. There has been a considerable improvement in investor relations in the U.K. in the past few years. The author suggests that more information could be provided by the U.K. Clearing Banks—information which is readily available within the banks—which would enable the investment analyst to make important comparisons from data which is not at present available to him. 相似文献

Randomly censored covariates arise frequently in epidemiologic studies. The most commonly used methods, including complete case and single imputation or substitution, suffer from inefficiency and bias. They make strong parametric assumptions or they consider limit of detection censoring only. We employ multiple imputation, in conjunction with semi-parametric modeling of the censored covariate, to overcome these shortcomings and to facilitate robust estimation. We develop a multiple imputation approach for randomly censored covariates within the framework of a logistic regression model. We use the non-parametric estimate of the covariate distribution or the semi-parametric Cox model estimate in the presence of additional covariates in the model. We evaluate this procedure in simulations, and compare its operating characteristics to those from the complete case analysis and a survival regression approach. We apply the procedures to an Alzheimer's study of the association between amyloid positivity and maternal age of onset of dementia. Multiple imputation achieves lower standard errors and higher power than the complete case approach under heavy and moderate censoring and is comparable under light censoring. The survival regression approach achieves the highest power among all procedures, but does not produce interpretable estimates of association. Multiple imputation offers a favorable alternative to complete case analysis and ad hoc substitution methods in the presence of randomly censored covariates within the framework of logistic regression. 相似文献

Individuals with disabilities who complete post secondary education programs must be prepared to plan and direct their long-term careers. Despite recent legislation, students with disabilities exiting higher education continue to face obstacles such as negative employer attitudes, architectural barriers, and lack of necessary services and supports when attempting to access employment and pursue their careers. This article describes a comprehensive career-planning program designed to enhance employment opportunities for individuals with disabilities as they graduate from higher education. 相似文献

The current investigation examined performance on two laboratory-based gambling tasks, the Georgia Gambling Task (GGT; Goodie,
2003. The effects of control on betting: Paradoxical betting on items of high confidence with low value. Journal of Experimental Psychology: Learning, Memory, and Cognition, 29, 598–610) and the Iowa Gambling Task (IGT; Bechara, Damasio, Damasio, & Anderson, 1994. Insensitivity to future consequences
following damage to human prefrontal cortex. Cognition, 50, 7–15), as well as self-reported markers of gambling pathology using the Diagnostic Interview for Gambling Severity (DIGS;
Winters, Specker, & Stinchfield, 2002. The downside: Problem and pathological gambling (pp. 143–148). Reno, NV: University of Nevada, Reno) among a sample of undergraduate students who are frequent card players.
Two hundred twenty-one participants (55 female and 166 male; mean age 19.21 years) who self-classified as playing cards at
least once per month completed these measures. Performance on GGT and IGT systematically related to gambling-related pathology
in several ways. Overconfidence and bet acceptance on the GGT, and myopic focus on reward on the IGT, predicted gambling related
pathology. GGT and IGT performance correlated with each other, but both contributed independently to predicting gambling pathology.
Card playing frequency predicted gambling pathology but not GGT or IGT performance. Discussion focuses on the role of biases
of judgment and risky decision making in pathological gambling. 相似文献

Several school performance indices were evaluated using achievement data from multiple longitudinally matched middle school student cohorts in a large district in the southwestern United States. Measures designed to index the within-cohort achievement status and growth of students as well as the status and growth-based changes that occur over years between different student cohorts were studied. Within- and between-cohort status and growth-based estimates of school performance were generated by applying simple and relatively complex statistical models to the longitudinal time-series data obtained on students. Results indicated that within-cohort status-based estimates were closely related to student demographics and between-cohort estimates were associated with cohort enrollment size and initial performance level. These results suggest that schools may often be rewarded and penalized on the basis of factors over which school personnel have limited or no control. Implications for the measurement and evaluation of school performance are discussed. 相似文献
