Given the high incidence of obesity and obesity-related health problems among low-income African American women, it is both timely and significant to study factors that contribute to obesity in this population. The perception of current body size (body image) and desired body size (body image ideal) has been associated with the development of anorexia and bulimia in white adolescent girls. Body images and ideals may also be related to the development of obesity among African Americans adolescent girls. This study examined the body images and ideals of 27 low-income African American mothers and their 29 preadolescent daughters. Results suggest that there is a relationship between mothers' perceptions of their daughters bodies and their daughters' body images. Preadolescent, low-income, African American girls have normal weight ideals rather than the ultrathin ideals typically found among white girls. Normal weight girls have ideals that are heavier than their body images. This population may be less motivated than those with thinner ideals to engage in behaviors that would prevent the development of obesity during adolescence. Health promotion programs for this population should acknowledge cultural body weight standards.This study was funded by the American Heart Association of Metropolitan Chicago.Received B.A from the University of Pennsylvania. Research interests include cross-cultural studies of body image, eating disorders, health risk perceptions, and health promotion programs.Received Ph.D. from in Clinical Psychology from Long Island University. Research interests include obesity prevention, binge eating, and cultural differences in eating behavior.  相似文献

There has been resurgence in evaluation of policy, reflected mostly by an increase in ex ante studies. Although there is a shift towards ex post evaluation, this has been gradual, resulting in a paucity of ex post evaluation literature. To address this gap, we apply a revisionist approach to evaluate a major public sector reform in the Bhutanese civil service. We conclude that it provides a more holistic approach for ex post evaluation policy, and also a more nuanced evaluation which moves us beyond the narrow binary view of success or failure in reform.  相似文献

Forensic analysis of bicomponent fibers using infrared chemical imaging   总被引:2,自引:0,他引:2  
The application of infrared chemical imaging to the analysis of bicomponent fibers was evaluated. Eleven nominally bicomponent fibers were examined either side-on or in cross-section. In six of the 11 samples, infrared chemical imaging was able to spatially resolve two spectroscopically distinct regions when the fibers were examined side-on. As well as yielding characteristic infrared spectra of each component, the technique also provided images that clearly illustrated the side-by-side configuration of these components in the fiber. In one case it was possible to prepare and image a cross-section of the fiber, but in general the preparation of fiber cross-sections proved very difficult. In five of the 11 samples, the infrared spectra could be used to identify the overall chemical composition of the fibers, according to a published classification scheme, but the fiber components could not be spatially resolved. Difficulties that are inherent to conventional "single-point" infrared spectroscopy, such as interference fringing and sloping baselines, particularly when analyzing acrylic type fibers, were also encountered in the infrared chemical image analysis of bicomponent fibers. A number of infrared sampling techniques were investigated to overcome these problems, and recommendations for the best sampling technique are given. Chemical imaging results were compared with those obtained using conventional fiber microscopy techniques.  相似文献

Significant needs exist for increased and better substance abuse treatment services in our nation's prisons. The TCU Organizational Readiness for Change (ORC) survey has been widely used in community-based treatment programs and evidence is accumulating for relationships between readiness for change and implementation of new clinical practices. Results of organizational surveys of correctional counselors from 12 programs in two states are compared with samples of community-based counselors. Correctional counselors perceived strong needs for new evidence-based practices but, compared to community counselors, reported fewer resources and less favorable organizational climates. These results have important implications for successfully implementing new practices.  相似文献

The article is concerned with inconsistencies in Politics among nations (PAN) and Scientific man versus power politics in relation to statements on geopolitics. The article attempts to place these works in the internal and external context of the period in order to ascertain the reason for the inconsistencies. The analysis begins with the context of the chief academic debates in political geography at the time and proceeds to explain the source of the inconsistency between the two books, using the text and archival materials. Following this, the works and criticisms of Halford Mackinder, James Fairgrieve and Nicholas Spykman are examined. The external contextual elements of the Second World War, the beginning of the Cold War and the awakening of American global power are considered as factors in the shift towards a more favourable view on geographical considerations in international relations in PAN. The conclusion that the article reaches is that there are two factors which explain the inconsistency, the integration of American thought on international relations with Morgenthau’s own ideas and the diverging purpose of the books.  相似文献
