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 article analyzes the impact of the Gramm-Rudman-Hollings (GRH) Act on federal budgetary and fiscal outcomes. Rather than portraying it as a two-on federal budgetary and fiscal outcomes. Rather than portraying it as a two-party game between Congress and the president, each with monolithic policy preferences, we view GRH as a multiparty negotiation game among advocates of different programs and agencies. In this game, agencies subject to sequestration and their congressional advocates have an incentive to reach a budget accord, while those exempt from sequestration do not. Consistent with this argument, we find that GRH has restrained outlays for nonexempt programs and that exempt programs have, if anything, experienced more rapid growth. Overall, GRH is estimated to have restrained outlays by $59 billion by fiscal 1989, and to have restrained outlays more effectively after the 1987 modifications in the Act. The Gramm-Rudman-Hollings Act signals another phase in the decade-long struggle between the White House and Congress over public spending priorities. Our final counterfactual analysis suggests that GRH partially returned federal fiscal and budgetary relationships and priorities to those that prevailed before Reagan. 相似文献

Central to this article is the question, “Are tax expenditure reports used?” State legislators serving on tax committees in ten states were surveyed regarding their use and their perceptions of others' use of tax expenditure report information. Responses indicate (1) strong acceptance and broad use of report information; (2) purposes and policy stages of use characteristic of technical information use; and (3) use focused predominantly on resource acquisition (revenue) policy rather than resource allocation (budget) policy. Thus it appears that tax expenditure reporting does not operate to secure budgetary control over tax expenditures, and consequently tax expenditures continue largely to escape budget scrutiny. 相似文献

A pervasive theme of the congressional politics literature is that the committee system is fundamental in determining the policy status quo. Such an assertion hinges crucially upon committees controlling their jurisdictions; congressional delegation is undermined if a committee can assert authority over any issue domain at any time. Yet, representatives may possess an incentive to support a policy proposal that would change the status quo, even if it entails disregarding procedures. Indeed, standard conceptualizations of how members of Congress make their voting choices assume that only the benefits and costs associated with a policy matter, and they do not consider institutional factors such as whether a bill emerged from the correct committee.This analysis examines whether representatives will sacrifice policy interests to preserve institutional features of the legislature. The effort in 1987 to curb smoking on airplanes — which became embroiled in a difficult-to-resolve jurisdictional dispute — serves as a vehicle to analyze how sensitive members are to such features. The results demonstrate that a sizable number put aside their [generally moderate] policy preferences and voted against limits on smoking for institutional reasons. These findings have important implications both for specifying the determinants of policy change and for understanding institutional stability. 相似文献
