The experimental evaluation of two components of a community intervention to prevent adolescent tobacco use are described. Youth antitobacco activities (e.g., peer quizzes, sidewalk art, poster and T-shirt giveaways, etc.) and family communications activities (pamphlets to parents and student quizzes of parents) were evaluated in two time-series experiments, each of which was conducted in two experimental and one control community. Students in Grades 6 and 8 and their parents were assessed in a series of four phone surveys in the first experiment and six phone surveys in the second. Implementation of the youth antitobacco and family communications activities led to significantly greater exposure of young people to antitobacco information. They led to increases in parent and youth knowledge about tobacco use and more negative attitudes toward tobacco. In Experiment 2, youths in intervention communities had significantly lower rated intentions to smoke. The findings suggest the value of a modular approach to community interventions for influencing the social context relevant to the onset of adolescent tobacco use.  相似文献

Masculine gender role stress is a theoretical construct that describes the stress created in men when they feel they are not meeting society's expectations for masculinity, or when the situation forces men to act in feminine-typed ways. The stress produced by these feelings or actions are thought to be related to negative psychological outcomes for men, but should be unrelated to well-being for women. The present study investigated the validity of the masculine gender role stress construct, especially with regard to the assumption that masculine gender role stress is related to negative psychological outcomes for men more than for women. Participants were a group of mostly Caucasian undergraduates. Results indicated that masculine gender role stress was related to depression, hostility, and anxiety, but to the same degree for both men and women. These findings suggest that, if MGRS is a valid construct, then researchers need to explore other ways in which this type of stress can negatively affect men, but not women.  相似文献

Our primary purpose in this article is to explore some of the issues, practical and conceptual, that arise in the attempt to study and cope with public policy controversies. We have organized the article into four sections. The first considers what problems a frame-critical approach seeks to address and explores, in particular, why social science methods seem unable to contribute to the resolution of public controversies. The second section asks what “frames” are and why they are critical to the study of controversy. Section three gives an overview of the elements in a frame-critical policy analysis and of the relationships between it and frame-reflective policy practice. In conclusion, section four examines the main issues that need to be addressed in analyzing and coping with policy controversies.  相似文献

In an important text, A Thousand Teachings, sometimes overlooked by scholars, Sankara expounds non‐dualist religion. This article analyses Sankara's thought for its theoretical and practical perspectives. First, the discussion views non‐duality from the viewpoint of ignorance. This pluralistic/dualistic perspective obscures the unenlightened seeker's vision of the Ultimate Truth. Secondly, the study examines Sankara's introduction of a transitional idea, Unevolved Name‐and‐Form (avyākrte nāmarūpe). Such an idea assists the seeker's intellectual progress from the state of ignorance to a rational understanding leading toward nonduality (Advaita Vedānta). Finally, the exposition clarifies Sankara's expression of the “knowledge of Brahman”. This fulfilling wisdom affects a transformation of the life experience of the unenlightened. Subsequently disciplined in meditation (parisamkhyāna), the persistent seeker develops into an experiencer of the non‐duality (advaitavāda).  相似文献

The possibility of a Psychonomic Society journal publishing program dates back to the very founding of the Society in 1959. The program was initiated by Clifford T. Morgan on his own, however, with the publication ofPsychonomic Science in 1964, followed byPsychonomic Monograph Supplements andPerception & Psychophysics within the next 2 years. In 1967, Morgan gave the journals to the Psychonomic Society, which has controlled them ever since. The structure of the journal program and the means of producing the journals have evolved since then, so that today the Psychonomic Society publishes six prominent journals in experimental psychology, all of them produced in-house.  相似文献

Three adults with profound mental retardation and very limited reading skills were transitioned to community living after spending more than 20 years in a residential facility. Community-based instruction was used to teach them to independently prepare meals. Directed rehearsal and prompting procedures were used to teach them those meal preparation skills that they were unable to perform independently. We present assessment, training and followup data on the preparation of a dessert by the three participants. Following an assessment on the steps needed to prepare the dessert, training was introduced in a multiple baseline across subjects design. Results showed that the participants were able to independently prepare the dessert in up to 21 pre-training and training sessions. Monthly followup for six months showed that they were able to independently prepare the dessert in various community settings of their choice.  相似文献

This paper explores some of the implications the statistical process control (SPC) methodology described by Pfadt and Wheeler (1995) may have for analyzing more complex performances and contingencies in human services or health care environments at an organizational level. Service delivery usually occurs in an organizational system that is characterized by functional structures, high levels of professionalism, subunit optimization, and organizational suboptimization. By providing a standard set of criteria and decision rules, SPC may provide a common interface for data-based decision making, may bring decision making under the control of the contingencies that are established by these rules rather than the immediate contingencies of data fluctuation, and may attenuate escalation of failing treatments. SPC is culturally consistent with behavior analysis, sharing an emphasis on data-based decisions, measurement over time, and graphic analysis of data, as well as a systemic view of organizations.  相似文献

Guided discretion statutes were designed to control arbitrariness and discrimination in capital sentencing. Using data from Supplemental Homicide Reports and Trial Judge Reports, this article examines the issue of racial disparity in Missouri's capital punishment process from 1977 through 1991. Findings from the three decision points examined suggest racial bias against the killers of whites, particularly if the offender is black, and a concomitant devaluation of black victims. The strongest effects noted are in the prosecutor's decision to charge homicide offenders with capital murder and to proceed to penalty trial in convicted capital murder cases. While the effects are not necessarily limited to the least aggravated categories, the effects of race are strongest when prosecutors and jurors are freed from the seriousness of the cases to consider other factors. The racial disparities are also apparent in mid-range cases up until the sentencing stage. However, disparities occurring earlier in the process are not rectified during sentencing. In fact, in the least aggravated cases, racial disparities are magnified at the sentencing stage.  相似文献
