Abstract The authors examined the relationship between binge drinking and other substance use among US college students, using nationally representative data from the 1995 National College Health Risk Behavior Survey implemented by the Centers for Disease Control and Prevention. Compared with nonbinge drinkers, current binge drinkers were significantly more likely to report “ever” using and current use of cigarettes, marijuana, cocaine, and other illegal drugs. The researchers also found that the more often students binge drank, the more likely they were to have ever used cigarettes, marijuana, cocaine, and other drugs, and the more likely they were to report current use of cigarettes and marijuana. Those who design programs to prevent binge drinking and use of other substances should take into account the reality that many students use more than one substance and that the more frequently students report binge drinking, the more likely they are to be using other substances as well. 相似文献

This article reviews the innovations in teaching research in social work education, including conceptual material and specific examples. There is attention to the ideological differences inherent in research and its instruction, methodology/technology innovations, and integrative and group approaches, among other developments. Examination of three major models of research instruction and their assumptions about the purpose of research in social work is presented. Discussion about ethical codes and curricular guidelines for social work programs in the United States and the United Kingdom provides a framework to understand the importance of teaching and learning research for the social work profession. 相似文献

Use of a conceptual model of societal drivers of ecological change in South Florida: Implications of an ecosystem management scenario 总被引:3,自引:0,他引:3

Human-dominated ecosystems such as in South Florida's Everglades region are greatly affected by societal actions and choices, and efforts to restore degraded ecosystems must take into account the societal drivers of ecosystem change. A conceptual model of societal-ecological interactions within the region illustrates connections between major societal drivers, such as water management and land use, and ecological stressors, such as loss of habitat and nutrient loading. Using the conceptual model as an initial guide for discussion, examination of a restoration scenario for the region shows that social and economic effects from activities proposed in a restoration scenario will likely affect most sectors of South Florida. Political effects from changing land and water management practices likely will be significant, as will the physical effects of changing water structures and management practices. Conceptual models such as this can aid in the initial stages of ecosystem restoration discussions and can assist in planning for subsequent social science evaluations of specific societal impacts of actual proposed governmental restoration alternatives. In crafting restoration scenarios, local, regional, and national decision makers can use conceptual models such as this to help broaden the early considerations of how possible future changes in societal drivers, including management choices, will change ecological stressors that affect ecosystem health. 相似文献

Abstract Through comparative sociological analysis, this paper discusses the patron-client relation in urban locality groups. The civil defense groups as urban locality groups which emerged during the chaotic situation after the Kanto earthquake in September 1923, and during Jakarta riots in May 1998, are the subjects of comparison. Even though the social background and historical context of the societies in question are different, both incidents share some similarities, in the rumors which accelerated the formation of civil defense group in almost every neighborhood. Further analysis on the formation, membership, and activities of the group reveals that the patron-client relation is not a mere power (vertical) relation, but also a life-cooperation relation. 相似文献

In this study, we examined the hypothesis that preschoolers' performance on emotion and cognitive tasks is organized into discrete processes of control and understanding within the domains of emotion and cognition. Additionally, we examined the relations among component processes using mother report, behavioral observation, and physiological measures of emotion control. Participants were 263 children (42 percent non‐White) and their mothers. Results indicated that the three approaches of measuring emotion control were unrelated. Regardless of the measurement method, a four‐factor solution differentiating emotion control and understanding and cognitive control and understanding fits the data better than did either of two two‐factor models, one based on domains of emotion and cognition across processes, and one based on processes of control and understanding across domains. Results of this research replicate those of Leerkes et al. in describing a differentiated underlying structure of emotion and cognition processes in early childhood while also extending these conclusions across samples and across measurement approaches for assessing emotion control. 相似文献

Each year, thousands of children who cross international borders are destined for homes with adoptive families. For most, this journey from their homeland brings them to loving new homes where they will thrive and prosper. For others, the journey is hazardous and the destination uncertain. 相似文献

The objective of this article is to evaluate the performance of the COM‐Poisson GLM for analyzing crash data exhibiting underdispersion (when conditional on the mean). The COM‐Poisson distribution, originally developed in 1962, has recently been reintroduced by statisticians for analyzing count data subjected to either over‐ or underdispersion. Over the last year, the COM‐Poisson GLM has been evaluated in the context of crash data analysis and it has been shown that the model performs as well as the Poisson‐gamma model for crash data exhibiting overdispersion. To accomplish the objective of this study, several COM‐Poisson models were estimated using crash data collected at 162 railway‐highway crossings in South Korea between 1998 and 2002. This data set has been shown to exhibit underdispersion when models linking crash data to various explanatory variables are estimated. The modeling results were compared to those produced from the Poisson and gamma probability models documented in a previous published study. The results of this research show that the COM‐Poisson GLM can handle crash data when the modeling output shows signs of underdispersion. Finally, they also show that the model proposed in this study provides better statistical performance than the gamma probability and the traditional Poisson models, at least for this data set. 相似文献

Adolescents like to watch TV and listen to the radio, even on school days, but their day contains, like for all other people, only 24 hours. What do those who use electronic media frequently neglect? Data from 14- and 16-year-old adolescents from 12 European countries and from the USA (EURONET sample) were analyzed (N = 3,250). The correlations between time spent using electronic media (EM) and 15 other daily activities were all negative, which is not surprising given the fact that the sum of all activities is bound to be 24 hours. We, therefore, calculated correlations between electronic media use and the proportions of each other activity within the remaining time. A clear pattern emerged. The method allowed us to identify “mandatory” activities that always have high priority, such as sleeping and attending school, and “optional” activities that enter into competition with electronic media use, including engaging in sports, playing music, leisure reading, and being with friends without media use. As to the mandatory activities, the correlations between media-using time and the proportions of remaining time were positive; relative to the optional activities, the correlations between media-using time and the proportions of remaining time were negative. While one might expect school homework to be regarded as mandatory, the correlation patterns identified it as optional. As to the average electronic media-using times, there were marked differences not only between the individual participants, but also between the countries. While Bulgarian adolescents spent an average of 2.37 hours of a regular school day using electronic media, French adolescents averaged only 1.72 hours. 相似文献

Abstract This study explores the bio-psychosocial context of HIV/AIDS in which eleven HIV-positive activist women from Khayelitsha negotiated the process of disclosing their HIV-positive status to significant others, specifically biological household members. The study is based on the narratives of a group of HIV-positive peer-educators in Cape Town, South Africa. The results suggest that community perceptions of HIV/AIDS are shaped by a wide variety of factors particular to the socio-cultural and political context of HIV/AIDS in South Africa. The process and outcomes of disclosure to others occurs within this shifting web of meanings, and in turn, reshapes them as people respond to the person who has just disclosed. Eight out of the eleven women disclosed to a close biological household member as these significant-others provided, or had the potential to provide, the appropriate support. Six of the eleven participants disclosed during the symptomatic phases of HIV/AIDS, while five were asymptomatic at the time. Four of the five who disclosed when asymptomatic were diagnosed while pregnant and had never experienced severe opportunistic infections. Additionally, these same four disclosed some time after diagnosis (nine months > t < two years). Of the six who disclosed in a state of ill-health, five disclosed immediately after diagnosis in order to access health-related social support. At this time, concerns regarding health and mortality superseded fears of rejection and discrimination due to AIDS-related stigma. The perceived potential benefits (social and health-related support) outweighed the perceived risks (stigmatisation and discrimination). When participants had never experienced serious illness, they disclosed in order to educate loved-ones, gain emotional support or challenge false popular perceptions of HIV/AIDS. 相似文献
