Rainwater's assertion that blacks have low self-evaluations because they receive more negative evaluations from other blacks than whites receive from other whites is challenged here by reference to Heiss and Owens evidence that negative self evaluation among blacks is limited to work-related traits. Substantial support was found for our major hypotheses that, compared to whites, (1) blacks would report more negative evaluation of “most men” but not of “most women” (since the provider role is traditionally ascribed primarily to men), and (2) the more negative evaluation of “most men” by blacks would be limited to work-related traits. 相似文献

Where strength training has been used in conjunction with functional-task training in older people, not only have there been improvements in leg strength but also improved function has been measured (e.g., Skelton & McLaughlin, 1996). Many studies use participants from care homes rather than community dwellers. We investigated changes in leg power, balance, and functional mobility in community-dwelling sedentary men and women over 70 years of age (n = 6 for training group [TR]; n = 10 for control group [CN]). Progressive training took place over 24 weeks using seated and nonseated exercise. For TR, leg power increased 40%, from 108 +/- 40 to 141 +/- 53 W (p < .01); dynamic balance increased 48%, from 22.3 +/- 7.9 to 33.1 +/- 6.1 cm (p < .01; functional reach); and functional mobility increased 12%, from 7.46 +/- 1.32 to 6.54 +/- 1.41 s (p < .05; timed walk). CN showed no significant change. In conclusion, a community-based exercise program led to large improvements in leg-extensor power, dynamic balance, and functional mobility. 相似文献

In January 2004, the National Collaboration for Youth approved a list of core competencies needed by entry-level youth development workers for effective youth development practice. This chapter provides an overview of these competencies, explaining why and how the list was created, outcomes, and recommendations for next steps. 相似文献

Adolescent suicide is increasing in the United States and the incidence of suicide gestures and attempts in juvenile correctional facilities is high. The attitudes of correctional staff toward adolescents and toward suicidal behavior may contribute to the increase. Suicide is often the outcome of a progression of problems that have isolated the adolescent from meaningful social relationships. Correctional staff must be aware of the phenomenon of adolescent suicide and be given training to deal with it effectively within the institution. Institutional staff have commonly seen suicide gestures or attempts as acting out behavior rather than a symptom of low self-esteem or inability to cope with institutional placement. This discussion examines the phenomenon of adolescent suicide and the impact the juvenile justice system has on its occurrence. It will also include an examination of interdisciplinary interventive strategies which can be used in an institutional setting. 相似文献

American Indian adults are thought to experience significant depressive symptoms at rates several times higher than adults in the general population, yet we know very little about factors associated with depressive symptoms among this under studied group. Many researchers have argued that depressive symptoms are associated with conflicts between American Indian traditional cultural values, practices, and beliefs and those of the majority culture. This report, based on a sample 287 American Indian adults from the upper Midwest, takes into account two measures of cultural effects: perceived discrimination, as one indicator of culture conflict, and traditional practices, as a measure of cultural identification. The results indicate that discrimination is strongly associated with depressive symptoms among American Indian adults and that engaging in traditional practices is negatively related to depressive symptoms. Moreover, interaction effects between perceived discrimination and traditional practices indicate that engaging in traditional practices buffers the negative effects of discrimination among those who regularly participate in them. 相似文献

Millions of workers suffer from upper extremity (musculoskeletal) disorders. Many of these workers are predisposed to upper extremity musculoskeletal disorders because of early exposure to ergonomic risks as students. Computer usage for four or more hours remains the greatest risk for upper extremity musculoskeletal disorders for workers and students alike. Developing preventative methods to reduce student exposure, and thus protect future workers from upper extremity musculoskeletal disorders later in life, requires an appropriate measure for upper extremity musculoskeletal disorder prevalence and related limitations for student functioning. Item response theory analysis was used to evaluate and further develop a upper extremity functioning scale for the student role. 相似文献

Welfare reform was examined for 39 Michigan families whose children have significant health or intellectual and behavioral disabilities. As a group, these families received little specialized assistance or services to address their unique needs. Family-cited barriers to self-sufficiency included poorly trained welfare caseworkers, limited public transportation, and inadequate child care. Having an older child was the only discriminating variable between working and non-working mothers. However, working mothers only had temporary positions with no benefits and low pay. All families, whether employed or not, lived below the poverty line. 相似文献

A Markov-chain faculty planning model to be used with institution-specific data is presented to describe and better understand the complex phenomena of faculty movement through an institution and on its relationship to salary costs, composition of the faculty, and faculty turnover rate. The model updates the earlier work done at Stanford University and Oregon State University by the addition of states for fixed-term appointments and for part-time FTEs to reflect accurately the current hiring trends at many institutions. The model is implemented and tested at two different institutions. The findings suggest that the model is a viable means of gaining useful insights and quantitative data on the faculty profile, salary costs, expected departures, and part-time trends. And further, when used as a planning tool, and the model apparently is comprehensive and flexible enough to analyze the probable effects, both in the short and long run, of alternative personnel policies on the faculty composition. 相似文献

Leadership — an underestimated profession. From a greenhorn of leadership to a qualified manager The author presents an empirical inquiery, basing on interviews with 10 recently appointed managers. She demontrates, that managers hardly ever are prepared for her job in advance. This may lead to several problems, up to a demotivation of all persons envolved. The author proposes a procedure of personal development with three elements: seminars to impart knowledge, employment of internal mentors and of external coaches. 相似文献
