This study evaluated the efficacy of Above the Influence (ATI), a national media-based health persuasion campaign to deter youth drug use. The campaign uses public service anti-drug prevention messages and targets youth between the ages of 14 and 16, a period of heightened susceptibility to peer influences. The evaluation utilized mall intercepts from geographically dispersed regions of the country. Theoretical impetus for the campaign combines elements of the theory of reasoned action (TRA), persuasion theory, and the health belief model. A series of structural equation models were tested with four randomly drawn cross-validation samples (N = 3,000). Findings suggest that awareness of ATI is associated with greater anti-drug beliefs, fewer drug use intentions, and less marijuana use. Congruent with the TRA, changes in beliefs and intentions are intermediate steps linking campaign awareness with behavior. This study provides further evidence of positive campaign effects and may strengthen reliance on mass media health persuasion campaigns as a useful adjunct to other programs targeting youth. 相似文献

We investigated physicians' attitudes about entering patients who cannot give informed consent or who are of a vulnerable population into clinical trials. A survey instrument asked a nationwide sample of practicing physicians about whether ten hypothetical patients could be enrolled in a phase I clinical trials. The impact of demographic variables on the number of scenarios viewed as completely or somewhat acceptable was analyzed via student's T tests or analysis of variance (ANOVA) as applicable. All significant (p<0.01) variables were entered into a multiple logistic regression model. Eighty-four percent of respondents indicated that at least one case scenario was acceptable. A majority of those who conduct clinical trials (62%), who had training in the ethics of clinical research (78%), and who sit on institutional review boards (IRBs) (83%) approved of at least one case scenario. Physicians approved of the entry of some patients who cannot give informed consent or who are of a vulnerable population into clinical trials. More effective education on the guidelines involving clinical research should be available to practicing physicians, residents, and medical students. There should also be assurance that physicians who conduct clinical trials or who sit on IRBs have the requisite knowledge about the ethics of clinical research. 相似文献

We examine the extent to which migration equilibria fail to exist in a global economy in which a specific division rule determines
the allocation of a perfectly divisible, nondisposable resource among individuals with single-peaked preferences who reside
in local economies. In particular, almost without exception, under the egalitarian, proportional, queuing, and uniform division
rules, migration equilibria fail to exist for some sets of preferences.

Using a personal social network framework, this qualitative study sought to understand how women in substance abuse treatment describe their network members' supportive and unsupportive behaviors related to recovery. Eighty-six women were interviewed from residential and outpatient substance abuse treatment programs. Positive and negative aspects of women's social networks were assessed via open-ended questions. Analysis was guided by grounded theory techniques using three coders. The findings extend classic social support concepts such as emotional, tangible, and informational support. Practice implications are presented in light of the potential roles network members may play in substance use and recovery. 相似文献

We analyze male occupational attainment using separate models in which occupational level is measured by indigenous socioeconomic index (SEI) scales, indigenous prestige scales, and a common prestige scale. Other than some consistent societal differences, the SEI scales produce highly similar results in both societies. In sharp contrast, both indigenous and common prestige scales indicate a stronger relative effect of origin (compared with education) on occupation in Great Britain. The dimensions of prestige and socioeconomic status thus seem to tap different aspects of the social mobility process, and the societies differ in the transmission of prestige but not socioeconomic status. 相似文献

This study examined how background and high school variables affected participants in either realizing their potential by completing a bachelor's degree or experiencing lost talent by not completing a bachelor's degree. A sample of participants who had demonstrated above average cognitive ability and had high postsecondary educational goals when in 8th grade was selected from the National Education Longitudinal Study of 1988 (national longitudinal data from 1988 to 2000; National Education, 2002). Several background and high school variables had strong effects on degree completion. Results were used to develop the Realized Potential or Lost Talent model. Implications for helping young people in their educational‐career development are included. 相似文献

Many impossibility results, like Arrow's Theorem, can be strengthened by using a domain constraint that is substantially weaker than the usual domain condition. 相似文献

The topic of risk has received extensive coverage in recent years. Hundreds of articles and numerous books have dealt with risk in occupations, safety, medicine, public health, and environmental pollution. However, in qualitative studies the subjective assessment of risk in everyday life have been badly neglected. Some of the reasons for this neglect, and its consequences for risk research, have been outlined in this paper. 相似文献

The dynamics of Young Men's career aspirations 总被引:1,自引:0,他引:1
Career aspirations have assumed a central place in our understanding of the process of social mobility, yet aspirations themselves have been subject to remarkably little scrutiny. We conduct an empirical analysis of the dynamics of aspirations in a cohort using data from the National Longitudinal Survey of Young Men. Our results indicate that (1) occupational aspirations decline with age; (2) the overwhelming majority of young men have high aspirations at some point; (3) occupational aspirations, highly unstable among teenagers, become more stable with age; and (4) differences by race and social origin grow with age, reflecting growing race and social class differences in educational attainment.An earlier draft of this paper was presented at the American Sociologial Association Annual Meeting, San Francisco, August 1989. 相似文献
