Abstract

Objectives: This exploratory study examined pre-event drinking, or pregaming, by US college students. Participants: 112 undergraduates from 10 Pennsylvania colleges participated. Method: A focus group, including a written questionnaire, was conducted at each institution. Results: Only 35.7% of the participants had not pregamed during the last 2 weeks. Pregamers consumed an average of 4.9 (SD = 3.1) drinks during their most recent session. Gender, class year, and other demographic variables did not predict pregaming. Heavier drinkers, and those stating that the average student pregamed 3+ times in the last 2 weeks, were more likely to report pregaming in the last 2 weeks. How much students drink when pregaming is influenced by how much they expect to drink later on. Conclusion: Pregaming presents a growing challenge for campus officials. Additional research is needed on the nature of the problem and which combination of prevention strategies might best address this behavior.  相似文献

Faire Formeln     
The literature on fair division has experienced a renaissance recently. Novel mathematical procedures promising an envy-free, socially efficient solution to conflicts over nearly indivisible goods play a particularly prominent role. This article presents a comparative experimental evaluation of three procedures. We examine to what extent features of the subjects of the procedures influence the choice in favor of one of the three negotiation protocols and the results of the division. Our analysis of the behavior of 119 subjects shows that psychological factors only affect the procedural choice. Dominance-seeking individuals tend to opt for those procedures that promise a fairer outcome than the relatively crude divide-and-choose-mechanism. In contrast, the outcome of the bilateral negotiations is determined by the attributes of the procedures. The strong influence of psychological factors at the initial stage of the bargaining process nevertheless casts strong doubts on the practicability of the procedures, recommended by the normative strand of game-theoretic negotiation analysis. The further development of ”fair formulas” for the resolution of redistributive conflicts should not neglect that the warring parties have to agree with the philosophy of the proposed bargaining protocol.  相似文献

Multidimensional empirical examinations of the adoption of innovations in organizations, and the influence of factors within each dimension on the phases of adoption, are scarce. This study examines the effects of environmental, organizational and top managers' characteristics on the initiation, adoption decision and implementation of innovation. Using a sample of approximately 1200 public organizations in the United States, we found that while each dimension accounts for unique variance in the adoption of innovation, organizational characteristics and top managers' attitudes toward innovation have a stronger influence than environmental and top managers' demographic characteristics. We also found no difference in the direction of effects of any antecedent, but did find differences in the significance of effects of several antecedents, on the phases of innovation adoption. We discuss the implications of these findings and suggest ideas for future research.  相似文献

Most traditional work by political sociologists conceives of social movement activity and politics as pertaining only to the public world and political activity as inherently masculine. Women are virtually invisible in these accounts. That the nature of political and social change is shaped by the organization of gender is a fact obscured in the conceptualizations typically employed. One such concept is political generation. Virtually no scholarly work has been done to analyze women in terms of political generations. Political generations are taken as sex-neutral phenomena with no hint that the organization of politics is based in the social organization of gender. Indeed, perhaps the major assumption of generational analysis, that generations are formed during youth and its accompanying period of rebellion and change, has not been subject to sustained scrutiny; this model may well capture the male, but possibly not, the female experience. Nevertheless, the generational model might be usefully applied to an understanding of the growth and transformation of the women's movement. When women are put at the center of inquiry, the notion of political generations takes on new meanings, and it raises questions about who, how, and when social groups come to experience similar perceptions and understandings of reality. This analysis begins with a selective summary of the assumptions and directions of generational analysis in social science. Contemporary media use of generational analysis follows with an eye to the ways in which media representation has shaped some women's movement dialogue. Feminist generational thinking is explored as it attempts to account for the history of the women's movements in the nineteenth and twentieth centuries and for the relations of young and old in the contemporary movement. Possible directions for further research and reformulation are suggested.  相似文献

Conducting culturally competent research is a challenge as the United States becomes increasingly multicultural. When conducting research on violence in Asian American communities, researchers need to consider how culture, race, and ethnicity influence definitions of concepts, and methodological issues such as research designs, sampling, developing and translating instruments, ethical issues, recruiting research participants, supervising and training interviewers, and disseminating findings. Examples from the authors' research studies on community violence in the Khmer community, domestic violence in the Chinese American community, and dating violence in Asian American groups are extrapolated to highlight various themes. A commitment to a research program that collaborates with the community under study and cultural experts is vital at every stage of the research process.  相似文献

In his articles (1966-1968) concerning statistical inference based on lower and upper probabilities, Dempster refers to the connection between Fisher's fiducial argument and his own ideas of statistical inference. Dempster's main concern however focuses on the “Bayesian” aspects of his theory and not on an elaboration of the relation between Fisher's and his ideas. This article attempts to work out the connection between those two approaches and focuses primarily on the question, whether Dempster's combination rule, his upper and lower probabilty based on sufficient statistics and inference based on sufficient statistics in Fisher's sense are consistent. To be adequate to Fisher's reasoning, we deal with absolutely continuous, one parametric families of distributions.This is certainly not the usual assumption in context with Dempster's theory and implies a normative but straightforward definition concerning the underlying conditional distribution; this definition however is done in Dempster's spirit as can be seen from his articles, (1966, 1968,a,b). Under those assumptions it can be shown that - similar to Lindley's results concerning consistency in fiducial reasoning (1958) - the combination rule, Dempster's procedure based on sufficient statistics and fiducial inference by sufficient statistics agree iff the parametric family under consideration can be transformed to location parameter form.  相似文献

Abstract

The purpose of this exploratory study was to examine the prevalence of parenting and child-caretaking among a sample of black men who have sex with men (MSM), as well as associations between parenting roles and sexual and reproductive health (SRH) factors. Parenting and SRH data were derived from a survey of 199 black MSM. Nearly half of the sample reported being a father or father-figure (44.4%), almost a third indicated serving as caretaker of a child (29.1%), and one in five have a biological child (20.1%). Over half of the sample reported at least one of these three parenting/child-caretaking roles (52.5%). Two significant differences were observed for sexual health variables: men with biological children were significantly more likely to report using condoms inconsistently (55.0% vs. 35.7%, p = .026) and engaging in transactional sex work (36.8% vs. 21.0%, p = .041). Given the observed prevalence, parenting and child-caretaking among black MSM warrant further inquiry as factors that may influence SRH outcomes and care utilization. Services and interventions tailored to black MSM should consider these men’s potential roles and responsibilities as parents and caretakers of children.  相似文献
