Considerable public health literature focuses on relationships between problematic human characteristics (e.g., psychopathology) and unhealthy behaviors. A recent movement termed positive psychology emphasizes the advantages of assessing relationships between human strengths (e.g., altruism) and beneficial health behaviors. The present study assessed social responsibility, an orientation to help or protect others even when there is nothing to be gained as an individual, and its relationship to HIV-relevant behaviors. In our sample of 350 men who have sex with men (MSM), social responsibility was negatively correlated with substance use and HIV risk behaviors. Men who had been tested for HIV and knew their HIV status—a behavior that helps men protect their partners but does not protect themselves from the virus—also scored higher in social responsibility. Interventions designed to reduce HIV risk behavior in MSM may benefit from efforts to promote human strengths.  相似文献

The impetus towards basing practice and policy decisions moreexplicitly on sound research requires tools to facilitate thesystematic appraisal of the quality of research encompassinga diverse range of methods and designs. Five exemplar toolswere developed and assessed in terms of their usefulness inselecting studies for inclusion in a systematic review. Thewidely used ‘hierarchy of evidence’ was adaptedand used to appraise internal validity. Four tools were thendeveloped to appraise the external validity dimensions of generalizability(two scales) and methods of data collection (two scales). Methodsof combining the scores generated by each tool were explored.Qualitative and quantitative studies were appraised, not separatedinto two spheres but by using complementary tools developedto appraise different aspects of rigour. There was a high levelof agreement between researchers in applying the tools to twenty-twostudies on decision making by professionals about the long-termcare of older people. The scales for internal validity and generalizabilitydiscriminated between the qualities of studies appropriately.The two tools to appraise data collection gave diverse results.Excluding studies that scored in the lowest category on anyscale appeared to be the scoring system that was most justifiable.This approach is presented to stimulate debate about the practicalapplication of the evidence-based initiative to social workand social care. This study may assist in developing clearerdefinitions and common language about appraising rigour thatshould further the process of selecting robust research forsynthesis to inform practice and policy decisions.  相似文献

Rural dwelling elders who experience mental health problems often have difficulty finding help since rural communities often lack adequate mental health service providers. This paper reports on the initial phase of a 5-year, interdisciplinary clinical research study that is testing the effectiveness of providing a home delivered, therapeutic psychosocial intervention, aimed at improving the emotional wellbeing and the quality of life of medically frail elders who live in rural communities. In the early phases of this study, the clinical research team encountered a number of interesting and often unanticipated challenges as it attempted to recruit study participants and provide services to them. In this article, we examine these challenges and share what we have learned so far about providing mental health services to elderly persons living in rural environments.  相似文献

This paper presents a formal framework that purports to capture some aspects of Kant's theory of freedom. In particular, we argue that the analysis sheds further light on Kant's distinction between a negative and a positive concept of freedom. The paper shows that the two concepts are not equivalent: we not only argue that in a Kantian perspective negative freedom need not entail positive freedom, but also that there are situations in which a person can be said to be positively but not negatively free (in a Kantian sense).  相似文献

We know from Li's theorem (1993) that the stability set of order d may be empty for some preference profiles. However, one may wonder whether such situations are just rare oddities or not. In this paper, we partially answer this question by considering the restrictive case where the number of alternatives is the smallest compatible with an empty stability set. More precisely, we provide an upper bound on the probability for having an empty stability set of order d for the majority game under the Impartial Weak Ordering Culture assumption. This upper bound is already extremely low for small population and tends to zero as the number of individuals goes to infinity.  相似文献

The rush to judgment about the social effects of the new communications media has branded them as positive and negative in equal measure. Alienation from "real world" relationships coupled with a lack of social regulation within the medium is balanced by liberation from the influences, inequalities, and identities to which people are subjected in face-to-face interaction. We argue that such general conclusions may in fact be turned upside down and propose that these media may actually strengthen social bonds but also reinforce power inequalities. Reviewing evidence of our research with university students, employing the social identity model of deindividuation effects, we show how these technologies can often be more "social," and socially regulated, than face-to-face interaction.  相似文献

Theoretical models or frameworks of change in human service organizations, both governmental and non-governmental, must adapt to the changing circumstances faced by such organizations in the later 1980s and 1990s. Too often change no longer means innovation initiated from within a service organization in order to improve service to its clients, but rather change engendered or enforced from outside the organization which may have uncertain or adverse implications for clients, target groups, or staff. Major changes may have to be implemented within tight time limits and in situations of high intra- and inter-organizational conflict. In such situations, sequential models of organizational change based upon a rational problem solving process, developed during the more favourable era of the 1970s, may be of limited use. A complementary framework for analysis and action planning can be built upon four dimensions of change identified here as rational-empirical, social-systems, power-politics and values-vision. These dimensions offer a comprehensive framework for understanding and intervening in various aspects of the change process, such as assessing the forces for and against change, preparing an organization for change, building up a change system, selecting change strategies, and evaluating a change process. Such a framework can be useful to those seeking to influence change in various alternative directions.  相似文献
