This study examines African American faith based leaders’ attitudes and beliefs about providing HIV prevention education and services to adolescents. Using a convenience sample, we identified priority adolescent health issues, attitudes about abstinence messages, and willingness to provide and participate in HIV prevention. Leaders identified drugs, gangs, alcohol, sex, and pregnancy as priority health issues affecting youth in their institutions. Leaders’ strongly preferred to emphasize abstinence messages. Although leaders were willing to provide youth with health education, they were not willing to discuss specific behaviors associated with HIV transmission. African American churches provide a venue to reach African American youth; however, there are limitations to relying on faith-based HIV prevention services. HIV prevention education should continue to be supplemented via parents, schools, and public health agencies.

Every significant piece of public policy, every important generalization in history, economics, political science, and sociology depends on (largely unevaluated) assumptions about human nature. Personality psychology concerns the nature of human nature; it is, therefore, concerned with one of the most powerful and dangerous forces on earth. Developing adequate methods for conceptualizing human nature and forecasting significant components of social behavior-for example, integrity, creativity, leadership-would seem to be a matter of real urgency. Nonetheless, personality psychology has a minor and marginal status in academic psychology. I have spent my career trying to understand the origins of human behavior, trying to develop measurement models for capturing key elements of social performance, and trying to defend the study of personality against the complaints of a seemingly endless supply of academic critics.  相似文献

A standing individual can use several strategies for modulating pushing force magnitude. Using a static model, researchers have shown that the efficacy of those strategies varies considerably. In the present article, the authors propose a human motor control dynamic model for analyzing transients that occur when an individual is asked to modulate force magnitude. According to the model, the impedances of both the upper and the lower limbs influence the time course of force variations and foot placement has a profound effect on pushing force dynamics. With a feet-together posture, the center of pressure has a limited range of motion and changes in force may be preceded by initial changes in the opposite direction; that is, to decrease force, an individual must first increase force. When the feet are placed apart, individuals can move the center of pressure over a much larger range, thereby modulating pushing force magnitude, without reversing behavior, over a larger range of force magnitudes. Therefore, the best way to control pushing force at the hand may be by using the foot.  相似文献

We examine socioanalytic theory from a leadership perspective and extend this research to examine the mediating mechanisms through which leader getting ahead motive and social competence influence leader effectiveness outcomes. A first-stage moderated mediation model was tested and supported, positioning the Leader Motive to Get Ahead × Political Skill interaction as influencing perceived institutional effectiveness and follower satisfaction with one’s leader through leader initiating structure behavior. This research both supports the relevance of socioanalytic theory for predicting leadership outcomes and extends socioanalytic theory to examine a mediating mechanism through which the interaction of the leader getting ahead motive and social competencies affects relevant performance outcomes. Contributions, strengths and limitations, directions for future research, and practical implications are discussed.  相似文献

Research findings suggest that switching between competing response sets can be resource demanding. The current study focused on concurrent health-relevant physiological effects of task switching by assessing cardiovascular response at varying levels of switch frequency. The participants performed a response-switching task at three different levels of response set switching frequency (low, medium and high) while measurements of blood pressure and heart rate were taken. One group was exposed to response-switching frequency conditions in the order low → medium → high, while the other group was exposed to the same task conditions in the reverse order (i.e. high → medium → low). The results showed that the participants in the low → medium → high switch frequency group recovered faster from initially heightened systolic blood pressure when compared with participants in the high → medium → low group. It is concluded that the results point to a physiological "carry over" effect associated with beginning a task at rapid response switching frequency levels, and suggest the importance of habituation to task demands as a means of offsetting potentially unhealthy levels of reactivity. Implications for modern work environments are discussed.  相似文献

We examined the associations between mental disorders and suicidal behavior (ideation, plans, and attempts) among new soldiers using data from the New Soldier Study (NSS) component of the Army Study to Assess Risk and Resilience in Servicemembers (Army STARRS;= 38,507). Most new soldiers with a pre‐enlistment history of suicide attempt reported a prior mental disorder (59.0%). Each disorder examined was associated with increased odds of suicidal behavior (ORs = 2.6–8.6). Only PTSD and disorders characterized by irritability and impulsive/aggressive behavior (i.e., bipolar disorder, conduct disorder, oppositional defiant disorder, and attention‐deficit/hyperactivity disorder) predicted unplanned attempts among ideators. Mental disorders are important predictors of pre‐enlistment suicidal behavior among new soldiers and should figure prominently in suicide screening and prevention efforts.  相似文献
