Community-based efforts offer broad potential for achieving population-level reductions in alcohol misuse among youth and young adults. A common feature of successful community strategies is reliance on local coalitions to select and fully implement preventive interventions that have been shown to be effective in changing factors that influence risk of youth engaging in alcohol use, including both proximal influences and structural and/or environmental factors related to alcohol use. Inclusion of a universal, school-based prevention curriculum in the larger community-based effort is associated with the reduction of alcohol use by youth younger than 18 years of age and can help reach large numbers of youth with effective alcohol misuse prevention. 相似文献

In the United States about 17% of adolescents meet diagnostic criteria for mental, emotional, and behavioral disorders. Six million young people receive treatment services annually for mental, emotional, or behavioral problems. These problems affect 1 in 5 families and cost $247 million annually (O'Connell, Boat, & Warner, 2009). Some strategies for preventing mental, emotional, and behavioral disorders in young people have been developed, tested, and found to be effective in preventing the onset, persistence, and severity of psychological disorders, drug abuse, and delinquency. Unfortunately, tested and effective prevention policies, programs, and practices are not widely used (O'Connell, Boat, & Warner, 2009). This paper highlights recent advances in prevention science and describes some opportunities and challenges in advancing the use of science-based prevention in communities. The chapter concludes by exploring the potential role of social work education in developing a workforce ready to increase community access to effective prevention strategies. 相似文献

Bivariate correlation coefficients (BCCs) are often calculated to gauge the relationship between two variables in medical research. In a family-type clustered design where multiple participants from same units/families are enrolled, BCCs can be defined and estimated at various hierarchical levels (subject level, family level and marginal BCC). Heterogeneity usually exists between subject groups and, as a result, subject level BCCs may differ between subject groups. In the framework of bivariate linear mixed effects modeling, we define and estimate BCCs at various hierarchical levels in a family-type clustered design, accommodating subject group heterogeneity. Simplified and modified asymptotic confidence intervals are constructed to the BCC differences and Wald type tests are conducted. A real-world family-type clustered study of Alzheimer disease (AD) is analyzed to estimate and compare BCCs among well-established AD biomarkers between mutation carriers and non-carriers in autosomal dominant AD asymptomatic individuals. Extensive simulation studies are conducted across a wide range of scenarios to evaluate the performance of the proposed estimators and the type-I error rate and power of the proposed statistical tests.Abbreviations: BCC: bivariate correlation coefficient; BLM: bivariate linear mixed effects model; CI: confidence interval; AD: Alzheimer’s disease; DIAN: The Dominantly Inherited Alzheimer Network; SA: simple asymptotic; MA: modified asymptoticKEYWORDS: Bivariate correlation coefficient, bivariate linear mixed effects model, parameter estimation, confidence interval, hypothesis testing, type-I error/size and power 相似文献

This study of 76 married or cohabiting two-earner families examined the influence of spouse/partner involvement in childcare and other demand and resource variables on mothers’ and fathers’ perceptions of spouse/partner support for paid work. Gender had a significant influence on the relationship between spouse/partner involvement in childcare and support for paid work. Mothers were more likely to report support for paid work when their spouse/partner shared more of the responsibilities associated with childcare. Fathers were more likely to report support for work when their spouse/partner shared fewer of the responsibilities associated with childcare. The findings also suggest that fathers’ perceptions of spouse/partner support for work are more sensitive to ecological factors than are mothers’ perceptions of support for work. 相似文献

The present study examined the relationship between concurrent measures of adolescent fathers' parenting stress, social support, and fathers' care‐giving involvement with the 3‐month‐old infant, controlling for fathers' prenatal involvement. The study sample consisted of 50 teenage father–mother dyads. Findings from multivariate regression revealed that fathers' parenting stress was significantly and negatively related to fathers' care giving as perceived by both fathers and mothers. The relationship between support for father involvement provided by the young man's parents and father reported care‐giving involvement approached significance. Social support from both teenagers' parents buffered the negative influence of parenting stress on fathers' involvement with the baby. Policy and intervention implications are discussed. 相似文献

The evolution and problems of model management research 总被引:1,自引:0,他引:1
AA Baldwin 《Omega》1991,19(6)
Models are a key resource for organizational decision making. The diversity, complexity, and reusability of this resource result in the need for model management systems. The construction of a model management system involves a modeling task dimension and a design level dimension. The modeling task dimension consists of model formulation, model representation, and model processing. The design level dimension addresses the architectural requirements of a system from a user's standpoint and a computer system's standpoint.The numerous architectures suggested in the model management systems literature address isolated areas identified by these dimensions. The research surveyed in this paper indicates that the primary focus has been on the system view of model representation. Before model management systems can be widely used in organizations, model management researchers must explore systems that address all areas of the task and design level dimensions.In this paper, we identify and justify the necessary dimensions of model management research. Next, the existing model management research is critically reviewed. Finally, neglected research areas are discussed, and investigations necessary for the development of integrated model management systems are suggested. 相似文献

OBJECTIVE: The author's purpose in this study was to examine the relation between smoking cessation counseling self-efficacy, knowledge of smoking cessation counseling, motivation to counsel smokers, and barriers to performing smoking cessation counseling, relative to the smoking cessation counseling stage of change. PARTICIPANTS AND METHODS: Members of The American College Health Association, who are health-care providers (N=296), completed a survey measuring the predictor variables of knowledge, motivation, self-efficacy and perceived barriers, and the members' readiness for conducting smoking-cessation counseling with students. RESULTS: The majority reported that they were knowledgeable about smoking-cessation counseling practices, they were motivated to conduct counseling, and they had the confidence (self-efficacy) to perform smoking-cessation counseling effectively. Significant barriers to performing smoking cessation counseling included the lack of reimbursement for counseling, lack of training in smoking-cessation counseling, and lack of resources for follow-up. The author found a moderate negative correlation between self-efficacy for smoking-cessation counseling and barriers to performing smoking-cessation counseling. CONCLUSION: The results suggest that researchers should address the barriers that prevent health-care providers from performing smoking-cessation counseling. Interventions on increasing healthcare providers' counseling self-efficacy may be instrumental in moving them further along the stage continuum and increase their readiness to perform smoking cessation counseling. 相似文献

Economic provisioning continues to be the essence of ‘good’ fathering, and the work schedules associated with fathers' employment remain a key factor which shapes their involvement in childcare and domestic work at home. However, the relative impact of fathers' and mothers' employment hours on paternal involvement in childcare is unclear, and little is known about the longer-term impact, that is, whether a work arrangement organised when the child is under a year old has an impact on paternal involvement when the child is aged three. Here we focus on employed couples and explore the association that mothers' and fathers' employment hours have with paternal involvement when their child is three years old. Multivariate analysis using the UK's Millennium Cohort Study reveals that it is the mothers' employment hours when the child is aged three that has the largest association with paternal involvement in childcare at this stage in the child's life, independent of what hours the father works. Furthermore, both fathers' and mothers' employment hours when the child was nine months old have a longitudinal influence on paternal involvement when the child reaches three years old, but it is the hours worked by the mother when the child was aged nine months that has the stronger association with paternal involvement at age three. This suggests that mothers' work schedules are more important than fathers' for fostering greater paternal involvement in both the immediate and longer term. 相似文献
