This national survey of 309 marriage and family therapists examined what therapists do when their HIV-positive clients disclose that they are engaging in high-risk sexual behavior. The participants were given vignettes in which a fictitious client told the therapist about engaging in unprotected sex. Although the basic situations were the same, the client variables of age, gender, race, sexual orientation, and HIV status were systematically varied. The participants were more likely to break confidence regarding unsafe sex practices when their clients were male, young, gay, or African American. Moreover, therapists who were more likely to disclose were older, female, had less experience with gay/lesbian populations, were Catholic, were very religious, and were more likely to practice in urban areas. The authors discuss the implications of these and other findings. 相似文献

The Technology Acceptance Model (TAM) has been widely used to predict user acceptance and use based on perceived ease of use and usefulness. However, in order to design effective training interventions to improve user acceptance, it is necessary to better understand the antecedents and determinants of key acceptance constructs. In this research, we focus on understanding the determinants of perceived ease of use. Data from three experiments spanning 108 subjects and six different systems supported our hypothesis that an individual's perception of a particular system's ease of use is anchored to her or his general computer self-efficacy at all times, and objective usability has an impact on ease of use perceptions about a specific system only after direct experience with the system. In addition to being an important research issue in user acceptance research, understanding antecedents of perceived ease of use is also important from a practical standpoint since several systems in which millions of dollars are invested are rejected because of poor user interfaces. Moreover, the actual underlying problem might be low computer self-efficacy of the target user group. In such cases, training interventions aimed at improving computer self-efficacy of users may be more effective than improved interface design for increasing user acceptance. 相似文献

Decision support systems continue to be very popular in business, despite mixed research evidence as to their effectiveness. We hypothesize that what-if analysis, a prominent feature of most decision support systems, creates an “illusion of control” causing users to overestimate its effectiveness. Two experiments involving a production planning task are reported which examine decision makers' perceptions of the effectiveness of what-if analysis relative to the alternatives of unaided decision making, and quantitative decision rules. Experiment 1 found that almost all subjects believed what-if analysis was superior to unaided decision making, although using what-if analysis had no significant effect on performance. Experiment 2 found that decision makers were indifferent between what-if analysis and a quantitative decision rule which, if used, would have led to significant cost savings. Thus, what-if analysis did create an illusion of control: decision makers perceived performance differences where none existed, and did not detect large differences when they were present. In both experiments, decision makers exhibited difficulty realizing that their positive beliefs about what-if analysis were exaggerated. Such misjudgments could lead people to continue using what-if analysis even when it is not beneficial and to avoid potentially superior decision support technologies. 相似文献

Emerging research suggests that existing culture, including religious culture, serves to constrain and enable the rhetoric
and claims of social actors in situations of conflict and change. Given that religious institutions continue to have significant
authority in framing moral debates in the United States, we hypothesize that groups connected to each other through a religious
tradition will share similar orientations towards the moral order, shaping the kinds of rhetoric they use and the kinds of
claims they can make. To test this, we compare the official rhetoric of the 25 largest religious denominations on gay and
lesbian issues, as well as their orientation towards the moral order more broadly, with the rhetoric of each denomination’s
respective movement for lesbian, gay, bisexual, and transgender inclusion, affirmation, or rights. We use Kniss’ heuristic
map of the moral order to analyze and theorize about the patterns that emerge from these comparisons. Ultimately, we find
that the existing rhetoric of the parent denomination on gay and lesbian issues, along with the broader moral stances they
take, do appear to shape the rhetoric and ideologies of associated pro-LGBT organizations. This provides support for the notion
that existing culture, belief, and rhetoric shape the trajectories of conflict and change. 相似文献

This article explores how the topics of gender and diversity are being taught and defined in accredited marriage and family therapy programs through syllabi content analysis and interviews with selected faculty. We examined findings by program (master's and doctoral) and type of training (those that taught specific gender and culture courses and those that attempted to infuse gender and culture throughout the curriculum). We examined 39 syllabi from 21 master's and 18 doctoral training programs. In addition, we conducted 20 interviews with faculty members. (Eighteen were White/Caucasian, one was African American and one was Asian Indian.) Some variation in topic areas was found between master's and doctoral programs and between those programs that offered specific course content and those that offered infused course content. However, qualitative interview data reflected many similarities. Particularly apparent was the level of commitment, transparency, and experiential learning methods professors used, regardless of program level or type. 相似文献

The authors believe that solution-focused therapy can be enhanced by more overtly incorporating emotions into its theoretical framework and therapeutic strategies. They discuss the role of emotions in solution-focused therapy and offer several solution-focused interventions that utlize client affect. 相似文献

We define a partial ordering of distributions which is preserved under convolutions and scale transformations. Some properties of this partial ordering are developed and then used to give a new argument for Slepian's inequality (1962). 相似文献

An interdisciplinary workshop was convened by the George Washington University in June 2001 to discuss how to incorporate new knowledge about susceptibility to microbial pathogens into risk assessment and management strategies. Experts from government, academic, and private sector organizations discussed definitions, methods, data needs, and issues related to susceptibility in microbial risk assessment. The participants agreed that modeling approaches need to account for the highly specific nature of host-pathogen relationships, and the wide variability of infectivity, immunity, disease transmission, and outcome rates within microbial species and strains. Concerns were raised about distinguishing between exposure and dose more clearly, interpreting experimental and outbreak data correctly, and using thresholds and possibly linearity at low doses. Recommendations were made to advance microbial risk assessment by defining specific terms and concepts more precisely, designing explicit conceptual frameworks to guide development of more complex models and data collection, addressing susceptibility in all steps of the model, measuring components of immunity to characterize susceptibility, reexamining underlying assumptions, applying default methods appropriately, obtaining more mechanistic data to improve default methods, and developing more biologically relevant and continuous risk estimators. The interrelated impacts of selecting specific subpopulations and health outcomes, and of increasing model complexity and data demands, were considered in the contexts of public policy goals and resources required. The participants stated that zero risk is unattainable, so targeted and effective risk reduction and communication strategies are essential not only to raise pubic awareness about water quality but also to protect the most susceptible members of the population. 相似文献
