A quasi-experimental replication of an intervention for promoting tobacco control policies in Northwest Indian tribes is described and the process of intervention including issues of collaboration among research institutions and Indian organizations is discussed. The policy intervention was evaluated using a pretest-posttest design wherein 20 tribes that had served as wait-list controls now received the intervention. The intervention comprised a tribal representative attending a kickoff orientation; follow-up visits to the tribes; distribution of tobacco policy workbooks; and phone call consultations. Policy status and stringency were assessed by means of telephone interviews with two key contacts per tribe, and by a count of enacted policies. There were significant pre-post changes in the primary outcome measure, a composite summary score of tobacco policy stringency, and changes were also reflected in enacted policies. The intervention effects observed were similar to those found in the prior randomized trial and suggest a robust, disseminable intervention. Much of the success achieved was attributed to the role of an Indian organization in planning the project and implementing the intervention and evaluation protocols. 相似文献

Interpreting and responding appropriately to facial expressions of emotion are important aspects of social skills. Some children, adolescents, and adults with various psychological and psychiatric disorders recognize facial expressions less proficiently than their peers in the general population. We wished to determine if such deficits existed in a group of 133 children and adolescents with emotional and behavioral disorders (EBD). The subjects were receiving in-patient psychiatric services for at least one of substance-related disorders, adjustment disorders, anxiety disorders, mood disorders or disruptive behavior disorders. After being read stories describing various emotional reactions, all subjects were tested for their ability to recognize the 6 basic facial expressions of emotion depicted in Ekman and Friesen's (1976) normed photographs. Overall, they performed well on this task at levels comparable to those occurring in the general population. Accuracy increased with age, irrespective of gender, ethnicity, or clinical diagnosis. After adjusting for age effects, the subjects diagnosed with either adjustment disorders, mood disorders, or disruptive behavior disorders were significantly more accurate at identifying anger than those without those diagnoses. In addition, subjects with mood disorders identified sadness significantly more accurately than those without this diagnosis, although the effect was greatest with younger children. 相似文献

Using an inventory based on findings from several qualitative studies, this investigation developed eight dimensions distinguishing successful senior managers from those who had derailed. Results showed that bosses' ratings of 86 successful senior managers on the eight dimensions were significantly higher than those of 83 who had derailed, providing empirical support for many of the earlier qualitative findings. Comparing the successful managers to the derailed suggests dimensions otherwise overlooked which are important to consider when assessing managerial talent. 相似文献

This address briefly traces post-1940 U.S. science policy from the science policy agenda set forth by Vannevar Bush in 1945 through the recent congressional task force on science policy. Although there are many factors influencing science policy, the focus here is on presidential influence. The effects of U.S. science policy on science are traced by looking at funding patterns in general, as well as at those for behavioral science. The influence of politics on the ability of scientists to freely communicate scientific information is examined. Finally, the role of politics in scientists’ access to computing resources is explored. Presented here is a side of science not often seen by those at the bench. 相似文献

Although it has been suggested that the early play experiences of girls and boys may contribute to gender differences in cognitive and social development, empirical support for this hypothesis is limited. This paper reports the development of a system of toy classification and may permit a more programmatic investigation of this problem. One hundred adult subjects rated 50 children's toys on 12 “functional” dimensions. Results showed that these toys could be reliably described according to multidimensional similarities and that toys considered appropriate for girls differed in many ways from those considered appropriate for boys. Thus this system may allow us to test more systematically the hypothetical relationship between sex-typed toy play and the development of differential cognitive and/or social skills in girls and boys. 相似文献
