The study examined the relationship between impulse control and violence in terms of past feelings and acts among African
American males enrolled in Historically Black Colleges and Universities. Data were gathered from a sample of 1,874 male undergraduates
in eleven colleges and universities with predominantly African-American students. Less than six percent were classified as
impulsive, and even less than half of the impulsive males had past feelings and acts of violence. The study offers strategies
for impulse control which may help to further minimize incidents of violence on the college campus. 相似文献

Pigs are a valuable animal model for studying neurodevelopment in humans due to similarities in brain structure and growth. The development and validation of behavioral tests to assess learning and memory in neonatal piglets are needed. The present study evaluated the capability of 2-week old piglets to acquire a novel place and direction learning spatial T-maze task. Validity of the task was assessed by the administration of scopolamine, an anti-cholinergic drug that acts on the hippocampus and other related structures, to impair spatial memory. During acquisition, piglets were trained to locate a milk reward in a constant place in space, as well as direction (east or west), in a plus-shaped maze using extra-maze visual cues. Following acquisition, reward location was reversed and piglets were re-tested to assess learning and working memory. The performance of control piglets in the maze improved over time (P < 0.0001), reaching performance criterion (80 % correct) on day 5 of acquisition. Correct choices decreased in the reversal phase (P < 0.0001), but improved over time. In a separate study, piglets were injected daily with either phosphate-buffered saline (PBS; control) or scopolamine prior to testing. Piglets administered scopolamine showed impaired performance in the maze compared to controls (P = 0.03), failing to reach performance criterion after 6 days of acquisition testing. Collectively, these data demonstrate that neonatal piglets can be tested in a spatial T-maze task to assess hippocampal-dependent learning and memory. 相似文献

The purpose of this study was to explore whether stuttering severity or therapy involvement had an effect on the attitudes that individuals who do not stutter reported towards people who stutter (PWS). Two hundred and sixty (260) university students participated in this study. Direct survey procedures consisting of a 25-item semantic differential scale were utilized. Comparisons of the effects of stuttering severity, level of therapy involvement, and the interaction of these variables were completed. Results suggested that both stuttering severity and therapy involvement had significant effects on participants' attitudes towards PWS. Findings of this study support past research studies that has found that individuals who stutter mildly are perceived more positively than those who are severe. Similarly, the data supported past research that has found that PWS that attend therapy are perceived more positively than those who do not attend therapy. Surprisingly, the interaction of these variables was not significant. EDUCATIONAL OBJECTIVES: The reader will be able to: (1) explain the possible effects of listeners' attitudes toward stuttering on the lives of PWS; (2) discuss how different factors might alter listeners' attitudes towards stuttering; (3) delineate how stuttering severity and involvement in therapy might impact listeners' attitudes towards PWS. 相似文献

This article aims to describe a theoretically-informed community engagement model which delivers a suite of child safety, peace and health interventions.We provide an overview of critical concepts that inform the community engagement approach that underpins the implementation of the Ukuphepha Child Safety, Peace and Health Programme (UCSPHP), in low-income neighbourhoods just outside Johannesburg, and on the periphery of Cape Town, South Africa. Our analysis is framed within a participatory approach and suggests the importance of six interconnected community engagement pathways: relationship-building; community-centred learning; social justice and contextual congruence; the facilitation of democratic traditions; strengthening the case for community services; and the affirmation of local social economies. 相似文献

This quasi-experimental study explored the association of perceived racism and seeking social support to vascular reactivity in a college sample of 110 Black women. Perceived racism and seeking social support were assessed via self-report, and vascular reactivity was measured before and during a standardized speaking task. Hierarchical regression analyses indicated that perceived racism was positively related to changes in systolic blood pressure. These analyses also indicated that seeking social support moderated the relationship between perceived racism and systolic blood pressure changes. This interaction effect persisted after controlling for several potential confounders. Follow-up regression analyses showed that perceived racism was positively associated with reactivity among participants who were low in seeking social support. A significant relationship was not observed between perceived racism and systolic blood pressure changes among participants who were high in seeking social support. Perceived racism and seeking social support were not significantly associated with changes in diastolic blood pressure. These findings highlight the importance of examining psychosocial factors that may mitigate the hypothesized relationship between perceived racism and reactivity. 相似文献
