Athletics is the most prominent extracurricular activity in U.S. secondary schools in terms of student participation and school budgets. The latter is often justified on the grounds that healthy bodies produce healthy minds, that school sports boost school spirit, and that participation in school-based sports increases students' self-esteem. In this article we examine the interrelationships among participation in a school-based sport and the benefits assumed to be associated with it. Specifically, we test a model that postulates that school spirit, operationalized as attachment to school, and healthy bodies, operationalized as a sense of physical well-being, mediate the relationship between school sports and self-esteem. Data from the National Longitudinal Study of Adolescent Health on Caucasian and African American girls and boys were employed to test the model. School attachment and physical well-being absorbed the statistical effect of participating in a sport for all four gender-by-race groups. Among Caucasian girls a negative residual effect of sports participation was observed, which suggests that sports participation encapsulates multiple effects with contradictory influences. For African American girls school attachment by itself was not a significant mediator of the effect of sports participation on self-esteem. For all groups a sense of physical well-being was the more powerful mediator.  相似文献

一、一座新的研究所“国际日本文化研究中心”的创立,接受了国库3.08亿日元的捐助,所长梅原猛。主要研究领域是解释日本文化。这一研究中心在日本国内虽然不是唯一的,却处于国际日本研究的中枢地位。研究中心的目标是对日本文化进行国际性跨学科研究。此外为配合国内外的日本文化研究,提供有关日本文化研究的信息,组织国内外学者开展共同研究等学术活动。通过这种组织者的作用,该中心扮演了国际日本文化研究的主要角色。中心创立的前史可上溯到70年代。当时的大平正芳首相责令组成“文化时代小组”,  相似文献

This article presents the results of a study conducted with 243 Native American students who were part of a multi-ethnic sample of adolescents attending middle school in a large urban center in the Southwest region of the United States. Native adolescents who felt a stronger sense of belonging in their school were found to report a lower lifetime use of alcohol and cigarettes, lower cigarette and marijuana use in the previous month, lower frequency of current use of these substances, fewer substances ever used, and a later age of initiation into drug use than other Native students. Research implications are discussed in relationship to school environment, culturally-grounded prevention curricula, and school social work practice.  相似文献

工业化国家的大多数公民仅仅是通过间接的、被大众媒介所歪曲的信息图像来认识第三世界的。尽管他们从那些普及全球的图像中日益了解到第三世界的贫困、内乱和滥用人权,但似乎没有什么人去关心改变那些痛苦的现实,仿佛发展中世界不存在严重的问题。无知、漠不关心以及一种防范丧失人性化的方式,使得我们这些居住在工业化社会的人把第三世界视为有别于我们自己的另一个世界,他们的存在与我们毫不相干。  相似文献

In this paper, Samuelson's simplified version of the Easterlin theory (Samuelson 1976) is extended to a continuous-time model with three age groups. This approach enables one to apply the qualitative theory of non-linear differential equations to show the existence of Easterlin-type cycles. In contrast to the discrete time model we obtain information about the period length of the cycle.This research was supported by the Austrian Science Foundation under grant P6601.  相似文献

The paper deals with the relationship between the population growth and economic development in Yugoslavia and its republics, covering the period after the Second World War. Yugoslavia is a developing country with a specific demographic and economic structure which makes her unique in Europe. Its territory is comprised of both relatively developed regions where demographic transition is over, and underdeveloped regions with high natural increase of population where the demographic transition is only just beginning. Correlation and regression methods were used to quantify this relationship. The economic development and structural changes are discussed, relating to human factor. An adequate population policy through family planning is stressed as important in obtaining an increased return to scale with a more positive role of demographic factor.  相似文献

The authors develop an econometric model to examine the impact of migration on fertility in Greece in the period 1968-1986. In the model, the fertility equation is considered within a simultaneous equation system, and international migration is included as an explanatory factor of both fertility and per capita income.
