Large numbers of America's young people engage in multiple high-risk behaviors that may jeopardize their health and social development. Given the gravity of this situation, many federal agencies and national organizations have called for the implementation of school-based K-12 social competence and health promotion programs. Unfortunately, there is a gap between the comprehensive programs that policymakers are asking educators to implement and the limited scope, duration, and intensity of state-of-the-art health promotion programs that scientists have developed and evaluated. As a result, most schools currently adopt well-marketed programs that lack documented effectiveness. Although current research indicates that brief, well-designed, theory-driven competence promotion and health education programs produce short-term benefits, there have been no controlled, longitudinal field studies to evaluate the long-term effects of K-12 efforts. This paper proposes that policymakers and funding agencies support long-term collaborations among educators and scientists to develop and evaluate K-12 comprehensive social competence and health education programs and identifies critical issues that funded projects should address. 相似文献

A questionnaire measuring sexual attitudes, attitudes about women, and racial attitudes was administered to 350 White male college students. Sexual attitudes characterized by sexual guilt, emphasis on personal and social control of sexual expression, and depersonalization of sex were significantly positively correlated (p<.001) with attitudes that typified women in terms of traditional masculine—feminine stereotypes and good (nonsexual)—bad (sexual) dichotomies. These stereotyped and dichotomous attitudes about women and constricted and depersonalized sexual attitudes were both significantly positively correlated (p<.001) with negative racial attitudes. The implications of these results and other research suggested by this investigation are discussed.This report is based on a dissertation submitted in partial fulfillment of the requirements for the Ph.D. degree at Michigan State University, 1973. The author would like to express appreciation to Dozier W. Thornton for continued guidance and assistance as dissertation advisor. In addition, the author gratefully acknowledges the assistance of Donald L. Grummon, Andrew M. Barclay, and Jeanne E. Gullahorn, all of whom served on the dissertation committee. 相似文献

Subjective probability considered as a logic of partial belief succumbs to three fundamental fallacies. These concern the representation of preference via expectation, the measurability of partial belief, and the normalization of belief. 相似文献

Developing survey measures of religion is deceptively difficult. As religion in America becomes more diverse and research projects become more global, finding a shared vocabulary that taps into concepts of interest and selecting response categories that capture the full range of choices becomes ever more challenging. This research project introduces new tools and techniques for exploring and evaluating past survey measures of religion, including a new software tool that draws on the ARDA's massive collection of survey measures. We offer two examples to demonstrate how these resources can serve to evaluate past survey measures of religion and improve future measures. 相似文献

This meta‐analysis investigates the degree to which achievement is positively associated with motivation within situations characterized by positive, negative, and no interdependence. First, the relative effects of positive, negative, and no interdependence on motivation and achievement were determined. Then the amount of variance in achievement explained by motivation (and vice versa) was calculated. In all, 629 independent studies were included, representing 26 different countries. Results also showed that motivation accounted for 14% of the variance in achievement (and vice versa). When the lowest‐quality studies were eliminated, the percentage of achievement explained by motivation increased to 24%. Positive interdependence resulted in greater motivation and achievement than did negative or no interdependence. Implications for theory and application are discussed. 相似文献

A taxonomy of part-whole or meronymic relations is developed to explain the ordinary English-speaker's use of the term “part of” and its cognates. The resulting classification yields six types of meronymic relations: 1. component-integral object (pedal-bike), 2. member-collection (ship-fleet), 3. portion-mass (slice-pie), 4. stuff-object (steel-car), 5. feature-activity (paying-shopping), and 6. place-area (Everglades-Florida). Meronymic relations ore further distinguished from other inclusion relations, such as spatial inclusion, and class inclusion, and from several other semantic relations: attribution, attachment, and ownership. This taxonomy is then used to explain cases of apparent intransitivity in merological syllogisms, and standard form syllogisms whose premises express different inclusion relations. The data suggest that intransitivities arise due to equivocations between different types of semantic relations. These results are then explained by means of the relation element theory which accounts for the character and behavior of semantic relations in terms of more primitive relational elements. The inferential phenomena observed are then explained by means of a single principle of element matching. 相似文献

This investigation extends previous research documenting differences in Chinese and European American infants' facial expressivity. Chinese girls adopted by European American families, nonadopted Mainland Chinese girls, nonadopted Chinese American girls, and nonadopted European American girls responded to emotionally evocative slides and an odor stimulus. European American girls smiled more than Mainland Chinese and Chinese American girls and scored higher than Mainland Chinese girls for disgust-related expressions and overall expressivity. Adopted Chinese girls produced more disgust-related expressions than Mainland Chinese girls. Self-reported maternal strictness, aggravation, positive expressiveness, and cultural identification correlated with children's facial responses, as did number of siblings and adults in the home. Results suggest that culture and family environment influences facial expressivity, creating differences among children of the same ethnicity. 相似文献
