Body image and weight loss beliefs and behaviors were assessed in 341 female and 221 male high school students. Estimates of body dissatisfaction varied depending on the measurement strategy used. Despite having similar weight distributions around the expected norm, girls were significantly more dissatisfied with their bodies than boys. Body Mass Index was positively related to body dissatisfaction in girls and boys, while higher exercise levels were related to higher body satisfaction in boys. Nearly two-thirds of girls and boys believed being thinner would have an impact on their lives, but the majority of girls believed this would be positive while the majority of boys believed this would be negative. Thirteen percent of female subjects reported using one or more extreme weight loss behavior at least weekly. Beliefs regarding the effectiveness of different weight loss measures were assessed. Weight loss behaviors in this Australian sample appear similar to comparable U.S. samples.Received Ph.D. from University of Tasmania.

This paper investigates the effectiveness of New Jersey's mandatory belt use law (MUL) by testing specifically for: (1) a safety effect, and (2) a risk-compensation effect that could offset (in part) any safety impact. The main findings are that injury severity declined significantly in the 22 months following implementation of the MUL; but that accident frequency increased significantly. The increase in accidents may be explained only partially by increased driving mileage. These findings suggest that the real safety effect of the law may have been diluted by risk-compensating behavior.This paper is based on a study conducted for the New Jersey Office of Highway Traffic Safety by the Rutgers University Bureau of Economic Research. We are grateful to William Ascher and two referees for useful comments. 相似文献

One of the major concerns associated with school voucher proposals is that they will only benefit those who leave public schools in favor of private schools. The children left behind in public schools are expected to necessarily be made worse off by such policies. This paper provides evidence suggesting that children left behind in public schools will also benefit. The available evidence suggests that, after a voucher plan, voter support for public schools will rise enough to increase the human capital of public school students, despite the presence of negative peer group effects. 相似文献

A transaction-based approach to policy intervention is presented. The approach overcomes a number of weaknesses in current approaches to policy intervention. The approach involves three main conceptual elements: transactions, transaction governance mechanisms, and governance principles. The transaction is taken to be the basic unit of analysis. Profiles of transactions vary along a number of transaction dimensions. Transaction governance mechanisms - such as, for example, government service, regulation, contracts, vouchers, markets, taxes, and self-service - are each suitable for governing transactions having particular profiles. A mechanism will fail when used to govern transactions not fitting the profile. Governance principles are criteria or expectations - for example, efficiency, justice and liberty - used to judge how well a mechanism fulfills or achieves important societal goals. Specific choices of governance mechanisms (from the set that are technically feasible) therefore should be made according to how well they satisfy these governance principles. Public high school education is used as an example to illustrate the approach. A number of conclusions are offered.This is a revised version of a paper presented at the Annual Meeting of the American Society for Public Administration Portland, Oregon, April, 1988. 相似文献

Abstract: Direct employment on public works (or day labour) was a powerful symbol of the possibilities for reform within capitalism in the early years of this century. It promised not only more work at times of high unemployment, but better conditions of employment. Further, there was the possibility of labourers, through their unions, having much greater control of their working lives. The major political battles were over whether governments should use day labour or contract. But, for the labourers themselves, the question of the nature of the administration of day labour became an increasingly important one. A sympathetic administration, such as that under E.W. O'Sullivan, not only meant great practical benefits for labourers; it served also as an example of what was possible through developing an alternative model of dealing with capitalist crises. However, in the case where a Labor government was unwilling to challenge the weight of traditional bourgeois economic thinking, day labour lost any pretence of being either model employment or a symbol for the future. In 1910–16, when labourers already had raised expectations of what day labour promised, such administration meant a growing alienation of labourers and their unions from the Holman Government and from Labor's parliamentary road in general. 相似文献
