Black gay and bisexual young men carry a disproportionate burden of HIV in the United States. This study explored Black gay and bisexual young men living with HIV's identification and interpretation of race‐specific cultural messages regarding substance use, sexual activity, and condom use. A total of 36 Black gay and bisexual young men living with HIV (ages 16–24, mean = 20.6 years) from four geographically diverse regions of the United States participated in qualitative in‐depth interviews. Results from this study elucidate the ways in which these young men interpret various forms of race‐specific cultural messages and experiences regarding substance use, sexual activity, and condom use. Participants discussed cultural messages and experiences promoting and discouraging condoms and substance use. Regarding sexual activity, only messages and experiences promoting sex were reported. Across all three categories, messages and experiences promoting risk were predominant. Data further revealed that socially transmitted cultural messages received by young men emanated from multiple sources, such as family, peers, sexual partners, community/neighborhood, and the broader society. Race‐specific cultural messages and experiences should be addressed in interventions for this population, and programs should assist young men in developing a critical consciousness regarding these messages and experiences in order to promote health and well‐being. 相似文献

The aim of this paper is to present a dynamic goal programming scheme. Throughout the revised literature, most of the dynamic goal programming approaches use target values on the final value of the objective functionals. In this paper, dynamic target values are assumed, so that they control not only the final values of the corresponding functionals, but their evolution along the planning period. As a result, the scalar problems are also dynamic ones, where the evolution of the deviation variables is minimized. A lexicographic dynamic goal programming algorithm is developed on these basis, and some considerations are made on the efficiency of the final solutions. © 1998 John Wiley & Sons, Ltd. 相似文献

During shaping, if the organism is engaged in behaviors other than the current approximation, the amount of time between reinforcers increases. In these situations, the shaper may resort to what is referred to as a “desperation‐driven click.” That is, after a period of no reinforcement, the shaper delivers one reinforcer for a nontarget approximation. Reports from professional animal trainers suggest that the animal may continue performing this new behavior, even if it is reinforced only once. This study attempted to model this phenomenon with college students. Results from the study demonstrated that a desperation‐driven click situation can be reliably produced in a controlled setting. When participants received one reinforcer for interacting with a new object following a period of no reinforcement, they interacted with the new object for a longer or equal amount of time as compared to an object that had a longer history of reinforcement. The results of this study have implications for the understanding of how reinforcement controls behavior. 相似文献

The authors examined the efficacy of a brief bystander bullying intervention on reducing alcohol use among high school students (N = 61). As hypothesized, high‐risk drinkers in the intervention group reported reduced drinking compared with control students at a 30‐day follow‐up. 相似文献

Professional pharmaceutical services may impact on patient’s health behaviour as well as influence on patients’ perceptions of the pharmacist image. The Health Belief Model predicts health-related behaviours using patients’ beliefs. However, health beliefs (HBs) could transcend beyond predicting health behaviour and may have an impact on the patients’ perceptions of the pharmacist image. This study objective was to develop and test a model that relates patients’ HBs to patient’s perception of the image of the pharmacist, and to assess if the provision of pharmacy services (Intervention group-IG) influences this perception compared to usual care (Control group). A qualitative study was undertaken and a questionnaire was created for the development of the model. The content, dimensions, validity and reliability of the questionnaire were pre-tested qualitatively and in a pilot mail survey. The reliability and validity of the proposed model were tested using Confirmatory Factor Analysis (CFA). Structural Equation Modelling (SEM) was used to explain relationships between dimensions of the final model and to analyse differences between groups. As a result, a final model was developed. CFA concluded that the model was valid and reliable (Goodness of Fit indices: x²(80) = 125.726, p = .001, RMSEA = .04, SRMR = .04, GFI = .997, NFI = .93, CFI = .974). SEM indicated that ‘Perceived benefits’ were significantly associated with ‘Perceived Pharmacist Image’ in the whole sample. Differences were found in the IG with also ‘Self-efficacy’ significantly influencing ‘Perceived pharmacist image’. A model of patients’ HBs related to their image of the pharmacist was developed and tested. When pharmacists deliver professional services, these services modify some patients’ HBs that in turn influence public perception of the pharmacist. 相似文献

Using data from the 1984–2014 General Social Survey, we employ cross classified random effects models to examine age-period-cohort changes in political tolerance by religion, incorporating religious belief, belonging, and behavior into the analyses. The results show large cohort and period based changes in political tolerance of the various religious traditions. The results also suggest that the primary driver of changes over time in political tolerance is best attributed to period effects, not cohort replacement, although there is some evidence of a cohort effect among Roman Catholics. Finally, our results demonstrate that aggregate data analyses can lead to noticeably different results and thus can mask substantial differences between groups. 相似文献

Making recognition decisions often requires us to reference the contents of working memory, the information available for ongoing cognitive processing. As such, understanding how recognition decisions are made when based on the contents of working memory is of critical importance. In this work we examine whether recognition decisions based on the contents of visual working memory follow a continuous decision process of graded information about the correct choice or a discrete decision process reflecting only knowing and guessing. We find a clear pattern in favor of a continuous latent strength model of visual working memory–based decision making, supporting the notion that visual recognition decision processes are impacted by the degree of matching between the contents of working memory and the choices given. Relation to relevant findings and the implications for human information processing more generally are discussed. 相似文献

The purpose of this study was to explore if and how social media might come to bear on people’s understanding of ethics. Participants were asked to complete online surveys regarding social media interaction and respond to 14 scenarios depicting ethical dilemmas. Our results suggest that social media and people’s perceptions of ethics do share a relationship. Specifically, we found that people who reported being exposed to ethical violations on social media were more likely to find our unethical scenarios to be personally unacceptable, to be of lower ethicality, and to react negatively to the content. These findings suggest that mere exposure to ethical violations is enough to produce awareness in people regarding ethical issues, which carries significant implications for ethics education. 相似文献
