CONCERN FOR THE ENVIRONMENT: A CROSS-NATIONAL PERSPECTIVE

Data from the International Social Survey Program indicate considerablevariation in the desire of respondents for increased spendingon the environment in Australia, Austria, Great Britain, theUnited States, and West Germany. This paper explores this variationwith the following objectives: (1) to determine the extent towhich the social bases of environmental concern are consistentacross nations; (2) to determine how the issue of the environmenthas been politicized in the five industrialized nations, focusingon the association of Old Leftist concerns and environmentalconcern; and (3) to determine the extent to which the socialbases of environmental concern can explain the cross-nationalvariation. The study usesa regression analysis, testing variablesrepresenting the social bases of environmental concern frompast research in the United States, a scale representing commitmentto the platform of the Old Left, and dummy variables for eachcountry. The results show that the social bases of environmentalconcern are the same in the five countries studied, includinga consistent positive association of Old Leftism with environmentalconcern. However, substantial variation between countries inthe overall level of concern remains. Potential sources of theremaining variation are examined.     

TFPS 教学用运动技术影片分析系统的教学应用

男子赛艇运动员与训练有关的有氧无氧能力和激素变化

观察了１５名男子赛艇运动员为期３０周训练中最大做功能力、最大乳酸值、最大摄氧量及心脏形态和功能的变化及相应时期的血清睾酮、游离睾酮、皮质醇的急慢性效应。在以力量训练为主的准备期，变化较小，以专项训练为主的准备期，心功能和有氧能力明显改善。最大负荷后及高强度训练１２周后，血清睾酮降低。提示在不同训练周期中力量—耐力训练应合理安排，有利于发挥机体适应能力。
