环境与发展--论发达国家与发展中国家之间的公平 总被引:1,自引:0,他引:1
徐犇 《国外社会科学情况》2005,(4):25-30
环境与发展问题关系到人类的生存和发展,是当代国际社会面临的重大课题。但正是在这一问题上,发展中国家与发达国家的立场存在着根本的分歧。本文通过论述保护环境的重要性和发展经济的必要性,以代际公平和代内公平理论为基础,展示了目前发展中国家和发达国家在环境与发展问题上不可调和的矛盾。 相似文献

To determine sex and race differences in muscle power per unit of muscle contraction, knee-extensor muscle power normalized for knee-extensor muscle volume was measured in 79 middle-aged and older adults (30 men and 49 women, age range 50-85 years). Results revealed that women displayed a 38% faster peak movement velocity than men and African Americans had a 14% lower peak movement velocity than Whites of a similar age when expressed per unit of involved muscle (p < .001). As expected, men exhibited greater knee-extensor strength and peak power per unit of muscle than women, but women had a faster knee- extension movement velocity per unit of muscle than men at the same relative strength level. Moreover, African Americans had greater knee-extensor muscle volume than Whites but exhibited lower knee-extensor strength and lower movement velocity per unit of muscle when tested at the same relative strength levels. 相似文献

Preparing social workers to effectively practice with the growing older population requires the identification of geriatric competencies for the profession. The John A. Hartford Geriatric Social Work Initiative provided the impetus and direction for a national strategy to improve the quality of preparation of geriatric social workers. The Geriatric Social Work Practicum Partnership Program (PPP) is the project with the Hartford Initiative that emphasizes field education. The Geriatric Social Work Education Consortium (GSWEC), one of the PPP programs, initiated the development of competencies for work with older adults. GSWEC utilized Geriatric Social Work White Papers and the pioneering work of the Council on Social Work Education's (CSWE) Strengthening Aging and Gerontology Education for Social Work's (SAGE-SW) comprehensive competency list as well as conducted focus groups locally to delineate key competencies for field education. The Coordinating Center for the PPP, located at the New York Academy of Medicine, led in collaboratively developing knowledge based skill competencies for geriatric social work across all 6 demonstration sites (11 universities). The competencies adopted across sites include skills in the following five major domains: values and ethics; assessment (individuals and families, aging services, programs and policies); practice and interventions (theory and knowledge in practice, individual and family, aging services, programs and practice) interdisciplinary collaboration; and evaluation and research. The identified competencies have proven effective in evaluating students (n = 190) pre- and post PPP field education. The implications for further development of competency driven education for geriatric social work are discussed. 相似文献

AbstractWe investigate the problem of testing for variance breaks in the case where the variance structure is assumed to be smoothly time-varying under the null. Since the classical tests are aimed to detect any change in the variance, they are not able to distinguish between smooth non constant variance and abrupt breaks. In this paper a new procedure for detecting variance breaks taking into account for smooth changes in the variance under the null is proposed. The finite sample properties of the test we introduce are investigated by Monte Carlo experiments. The theoretical outputs are illustrated using U.S. macroeconomic data. 相似文献
