In planning and implementing programs to treat substance abuse, it is important to understand which factors influence post-treatment abstinence.This article identifies and analyzes several variables important in predicting the likelihood of abstinence among substance abuse clients. The data used in this study was collected from 1,350 clients treated for alcohol or drug abuse in residential, halfway house, or outpatient facilities in Tennessee. We analyzed 22 variables as possible treatment outcome predictors by using two statistical procedures: stepwise logistic regression analysis and Quick, Unbiased, Efficient, Statistical Tree (QUEST) analysis, a tree-structured classification algorithm analysis. We found one pretreatment, five in-treatment, and three post-treatment variables to be significant predictors of treatment outcome: previous treatment history, perceived helpfulness of the treatment, simultaneous treatment for mental health, number of days in treatment,completion of treatment, special skills training during treatment, obtaining healthcare services for major physical health problem after treatment, living with someone using alcohol or drugs post treatment, and arrest record since treatment. 相似文献

The Demand-Control Questionnaire (DCQ), a 20-item scale that measures psychological work demands, job control and workplace social support, has frequently been used to assess occupational stress. The purpose of this study was to determine the test-retest reliability and internal consistency of the DCQ with sewing machine operators. Forty-six sewing machine operators completed the DCQ on two occasions with an 11-week time interval. A repeated measures analysis of variance model and subsequent application of generalizability theory were used to calculate the test-retest reliability of the subjects' ratings on the DCQ. Cronbach's alpha was used to determine the internal consistency of the scale. The test-retest reliability was 0.33 (95% confidence interval = 0.05-0.61), indicating fair reliability. Good internal consistency (Cronbach's alpha = 0.70) was found. The DCQ appears to be a reliable measure for assessing occupational stress in sewing machine operators. Workplaces need to place greater emphasis on the role of occupational stress in the prevention and treatment of musculoskeletal injuries among sewing machine operators. 相似文献

Neighborhood disadvantage, stress, and drug use among adults 总被引:1,自引:0,他引:1

This paper explores the relationships among neighborhood disadvantage, stress, and the likelihood of drug use in a sample of adults (N = 1,101). Using the 1995 Detroit Area Study in conjunction with tract-level data from the 1990 census, we find a positive relationship between neighborhood disadvantage and drug use, and this relationship remains statistically significant net of controls for individual-level socioeconomic status. Neighborhood disadvantage is moderately associated with drug related behaviors, indirectly through increased social stressors and higher levels of psychological distress among residents of disadvantaged neighborhoods. A residual effect of neighborhood disadvantage remains, net of a large number of socially relevant controls. Finally, results from interactive models suggest that the relationship between neighborhood disadvantage and drug use is most pronounced among individuals with lower incomes. 相似文献

We identify managerial challenges offered by an emergent nanotechnology innovation system in which knowledge is dispersed, asymmetric and contested. We argue the proposed models of knowledge absorption and transformation enhance existing theories of knowledge and emergent technology by recognizing how and why knowledge flows among the actors in emergent technology innovation system. We base our argument on combined research evidence from a Delphi study concerning the future of European manufacturing, from which a selected statement has been analyzed, and from analysis of the NanoManufacturing Institute at Leeds University, UK; specifically its work in building ties between different actors associated with nanotechnology. We conclude our paper with suggestions for future research. 相似文献

Differences between plant varieties are based on phenotypic observations, which are both space and time consuming. Moreover, the phenotypic data result from the combined effects of genotype and environment. On the contrary, molecular data are easier to obtain and give a direct access to the genotype. In order to save experimental trials and to concentrate efforts on the relevant comparisons between varieties, the relationship between phenotypic and genetic distances is studied. It appears that the classical genetic distances based on molecular data are not appropriate for predicting phenotypic distances. In the linear model framework, we define a new pseudo genetic distance, which is a prediction of the phenotypic one. The distribution of this distance given the pseudo genetic distance is established. Statistical properties of the predicted distance are derived when the parameters of the model are either given or estimated. We finally apply these results to distinguishing between 144 maize lines. This case study is very satisfactory because the use of anonymous molecular markers (RFLP) leads to saving 29% of the trials with an acceptable error risk. These results need to be confirmed on other varieties and species and would certainly be improved by using genes coding for phenotypic traits. 相似文献

Knowledge, Consequences, and Experience: The Social Construction of Environmental Problems 总被引:2,自引:0,他引:2
Jerry Williams 《Sociological inquiry》1998,68(4):476-497
Perhaps one of the most obvious yet difficult questions confronting sociologists concerned with large-scale environmental problems is an epistemological one: How do we know what we know about the state of the environment? This paper explores the realist and constructionist approaches to environmental-social problems and finds both inadequate as currently formulated. A case is made for a phenomenological constructionism that moves beyond relativism and simple definitional constructionism by exploring how we actually experience the world. This approach recognizes the existence of a natural world independent of our constructions, yet suggests that our knowledge of it is always mediated, indirect, and pragmatically motivated. 相似文献

Human relations training in many forms, the best known of which are encounter groups, enjoys wide popularity in industry, government and education. Some ‘professional’ objections to the running of such groups are raised, and it is proposed that these objections may be partially answered if there is a non-profit-making national association of group leaders whose function would be to provide a code of ethics to members and information to the public. As well as these professional objections involving the areas of leadership, screening and casualties, there are also objections to the 'process' of groups itself; to these latter objections arising out of an individual's sensibility and subjective interpretations of events, no compelling reply can be given. Affirmation of the interactions in encounter groups is likewise a subjective matter. 相似文献

The objectives of this research were to explore patterns of heterosexual activity in early adolescence and to examine the differential pathways to light and heavy heterosexuality. We utilized the National Longitudinal Survey of Canadian Children and Youth (NLSCY) in which heterosexual behaviors, as well as puberty, parenting processes, peer self‐concept, and problem behaviors were examined. The heterosexual activities of the majority of 12‐ and 13‐year‐old adolescents were largely confined to light activities of hugging, holding hands, and kissing. Heavy activities such as petting and sexual intercourse were reported less often. Using predictor variables from Cycle 1 of the NLSCY when participants were 10‐ and 11‐year‐olds, SEM analyses indicated that puberty and higher peer self‐concept shared significant direct pathways to both light and heavy heterosexuality. Heavy sexual activity, however, was uniquely associated with the risk factors of adolescent problem behaviors. Positive and hostile parenting styles were indirectly associated with light sexual activity through peer self‐concept. Positive and hostile parenting styles were also indirectly associated with heavy sexual activity through both peer‐oriented self‐concept and problem behaviors. Results support differential patterns and predictors of light and heavy sexuality in early adolescence. 相似文献

Nonprofit organizations in the United States depend on a diverse set of funding streams to sustain their operations. This study examines the ability of nonprofits to leverage funds from the private sector during the current economic downturn within four areas receiving federal funding for community and economic development. Both survey research and individual interviews were used to examine how nonprofits within these areas are incorporating their board members and community leaders to continue services during a time of resource scarcity. 相似文献

Problem gambling is significantly more prevalent in forensic populations than in the general population. Although some previous
work suggests that gambling and antisocial behavior are related, the extent and nature of this relationship is unclear. Both
gambling and antisocial behavior are forms of risk-taking, and may therefore share common determinants. We investigated whether
individual differences in personality traits associated with risk-taking, the Big Five personality traits, and antisocial
tendencies predicted gambling and antisocial behavior among 180 male students recruited for a study of gambling (35.0% non-problem
gamblers, 36.7% low-risk gamblers, 21.7% problem gamblers, and 6.7% pathological gamblers). All forms of gambling and antisocial
behavior were significantly correlated. Personality traits associated with risk-acceptance explained a significant portion
of the variance in problem gambling, general gambling involvement, and all forms of antisocial behavior. Antisocial tendencies
(aggression and psychopathic tendencies) explained a significant portion of additional variance in severe antisocial behavior
but not moderate or minor antisocial behavior. When controlling for personality traits associated with risk-acceptance, the
relationship between gambling and antisocial behavior was greatly diminished. The results are consistent with the hypothesis
that gambling and antisocial behavior are associated because they are, in part, different manifestations of similar personality
traits. 相似文献
