OBJECTIVE: Advertising influences the health-related behaviors of college-aged individuals. Cigarette manufacturers aggressively market to young adults and may exploit their affinity for alcohol when creating advertisements designed to increase cigarettes' appeal. Internal tobacco industry documents reveal that cigarette manufacturers understood the popularity of alcohol among young adults and sought to produce pertinent marketing strategies. METHODS: The authors conducted a content analysis of cigarette and alcohol advertisements in young adult-oriented magazines to investigate portrayed associations between cigarettes and alcohol. RESULTS: The content analysis revealed that 32 of 114 cigarette advertisements referenced alcohol and that those advertisements were more likely than others to portray active smoking. Conversely, 0 of 317 alcohol advertisements referenced cigarettes, and alcohol advertisements were only slightly more likely than cigarette advertisements to feature alcohol-related settings. CONCLUSIONS: Such advertising may detrimentally affect smoking patterns of college students. An understanding of these strategies can benefit on-campus tobacco control efforts.  相似文献

The adult day services (ADS) industry continues to grow and develop in providing care to larger numbers of older adults and their caregivers. Despite the growth in the number of programs and the changes in the way services are delivered, a systematic examination of the development of the ADS industry from a policy perspective has not been published since the mid-1990s. This article provides an analysis of the development of the ADS industry using the resource dependence model within a values-based context to determine whether public reimbursement opportunities are congruent with the needs of older adults and caregivers. Potential directions for the future development of the industry are presented through analysis of the collaborations of adult day providers with the providers of other services for older adults and the effort by public and private funders to connect quality outcomes and resources.  相似文献

This study examined alcohol use development from ages 13-20 years. The sample comprised 256 youth (50.4% female; 51.2% White, 48.8% African American) assessed annually for 6 years. A cohort-sequential latent growth model was used to model categorical alcohol use (non-use vs. use). Covariates included gender, race, income, parent marital status, risk taking, spiritual beliefs, parent alcohol use, family alcohol problems, family cohesion, friends' alcohol use, and normative peer use. The alcohol use trajectory increased steadily with age. Risk taking, friends' alcohol use, and normative peer use were positively associated with higher initial rates of alcohol use. Initial parent alcohol use and positive change in parents' and friends' alcohol use over time were related to an increase in alcohol use from ages 13-20 years.  相似文献

Hierarchical or multilevel models are based on the same fundamental concepts that apply to simple linear models. The linear forms of these models can be interpreted with relative ease as parameter estimates do not differ in magnitude or interpretation from standard non-hierarchical models. Non-linear hierarchical models, however, are more complex as the introduction of a random intercept means that parameter estimates must be interpreted as “subject-specific” rather than “population-averaged”. Depending on the specifics of the data being modeled, these parameters may be very different in magnitude. In this article we provide two examples of non-linear hierarchical modeling using administrative child welfare data. For each example, we estimate the odds of reunification for a cohort of children in California using both standard logistic regression models and random intercept models.  相似文献

This article presents recommendations from expert practitioners and researchers regarding future directions for research on elder abuse prevention. Using the Research-to-Practice Consensus Workshop model, participants critiqued academic research on the prevention of elder mistreatment and identified practice-based suggestions for a research agenda on this topic. The practitioners' critique resulted in 10 key recommendations for future research that include the following priority areas: defining elder abuse, providing researchers with access to victims and abusers, determining the best approaches in treating abusers, exploiting existing data sets, identifying risk factors, understanding the impact of cultural factors, improving program evaluation, establishing how cognitive impairment affects legal investigations, promoting studies of financial and medical forensics, and improving professional reporting and training. It is hoped that these recommendations will help guide future research in such a way as to make it more applicable to community practice.  相似文献

Meeting the Service Needs of Young Fathers   总被引:1,自引:1,他引:0  
Until the early 1980s, the needs of young fathers went largely unnoticed by policy makers and social service providers. Many programs for adolescent fathers originally started in order to benefit teenage mothers and their children (Leitch et al., 1993). It was later recognized that young fathers also need assistance to successfully become productive and responsible adults (Robinson, 1988; Leitch et al., 1993; Kiselica, 1995). Program designs have been based on a set of implicit assumptions: 1) if programs are offered, young fathers will enroll; 2) the services will meet the needs of participants; 3) once young men enroll in a program, they will use the services that are available; and 4) the services will be beneficial for recipients and will produce positive outcomes (Kiselica, 1995; Children and Youth Funding Report, 1998; Smith, 1997; DeParle, 1998). However, only limited research has been conducted to explore whether these assumptions are appropriate or to document programmatic successes and difficulties (Achatz and MacAllum, 1994; Marsh and Wirick, 1991; Sander, 1993). This paper adds to the literature by reviewing each of the assumptions within the context of one program's experience. It considers issues associated with outreach and enrollment, service delivery, and achieving desired outcomes for program participants.  相似文献

Abstract. This paper argues that preference change could explain, in part, the growth of within‐group wage inequality in the USA and the UK in the 1980s. The absence of such preference change in continental European countries might also help explain why their wage inequality did not rise in the same way. The argument relies on evidence from the World Values Surveys and uses an efficiency wage model of within‐group wage inequality where there are differences in the degree of discretion at work across firms and workers value not just the wage but also the degree of discretion on the job.  相似文献

THE DEVELOPMENT OF A FORGIVENESS SCALE   总被引:4,自引:0,他引:4  
This paper reports on the development, validity, and reliability of a self-report instrument designed to assess a respondent's perspective of pain resulting from relational violations and work toward relational forgiveness based on framework proposed by Hargrave (1994a). Presented here is the five-stage procedure used in the development of the Interpersonal Relationship Resolution Scale. Construct validity and reliability were determined from an initial sample of 164 subjects. Concurrent validity of the scal was supported by another sample of 35 respondents who took the Interpersonal Relationship Resolution Scal, the Personal Authority in the Family System Questonnaire, the Relational Ethics Scale, the Fundamental Interpersonal Relations Orientation-Behavior scale, and the Burns Depression Checklist. Finally, a predictive validity study of the scale was performed with a clinical and nonclinical sample of 98 volunteers. Data are presented that support the validity and reliability of the instrument, as will as the final version of the scale.  相似文献
