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.

Tax design decisions are subject to many influences, including economic and political realities. Those who make tax policy at the state level are under constant pressure to modify taxes and tax structures at the margin. In making their decisions, policy makers must assess and weigh the often conflicting advice that results from varying outlooks and interests among, as well as within, the groups providing such input.
Using Hawaii's liquor tax as a case study, this paper illustrates how seemingly innocuous policy meddling can turn a good tax into a bad one. The events that led the Hawaii Legislature to decide to substitute a flawed gallonage levy for a successful ad valorem tax are reviewed. The relative merits of ad valorem and per-unit liquor taxes are discussed. Implications of adoption of the gallonage tax are presented. Finally, the article discusses the reasons why meddling may be attractive to both taxpayers and those who levy the tax, and it concludes that tax design criteria should include disincentives to meddle as a reasonable principle of taxation.  相似文献

Undergraduate adult children of alcoholics (ACOAs; N=57) were compared to children of nonalcoholic parents (CONAs; N=100) on measures of the Beck Depression Inventory (BDI), selfesteem, and attributional style. ACOA status was determined using the Children of Alcoholics Screening Test (Jones, 1981). ACOAs were found to have significantly higher scores on the BDI and to have significantly lower self-esteem, as measured by the Index of Self-Esteem, than CONAs. ACOAs were also more likely to have a depressive attributional style, in that they perceived failure as more internal, stable, and global than CONAs. Further, females had significantly higher BDI scores than males.Received B.A. from West Virginia University.

This study examined the influence of pubertal timing upon family interactions in normal and psychiatric adolescent samples. An important feature of our approach is its emphasis upon micro-analysis of family behaviors (individual speeches) and family processes (theoretically specified speech pairings). Rather than assume that global family patterns (e.g., power) shift in response to pubertal changes, we follow how types of speeches and speech sequences are associated with different pubertal timing. Using the previously constructed family coding system, the Constrainig and Enabling Coding System, we found that on-time adolescents and their parents differed from both off-time groups (early or late). These results are discussed in terms of current implications and suggestions for future research.An earlier version of this paper was presented at the SRCD Study Group on Timing of Maturation, October, 1983, at the Education Testing Service, Princeton, NJ.

This essay asks what might be most usefully studied in future analyses of the impact of groups on the voting behavior of individuals. A dimension of group analysis so far neglected concerns some value orientations that affect the relevance of group consciousness to voting or other political behavior. In particular, the legitimacy of group political action and of group politics more generally is of central importance. Connected to such evaluations is the character of group comparisons, such as in group-focused relative power deprivation. Also of relevance are competing political value constellations, especially individualism and majoritarianism. By the use of a variety of National Election Studies and Wisconsin survey data, these themes are explored empirically to show the extent of a group focus that goes beyond the usual measures of group consciousness. Relative approval of group-based pluralism is also shown to affect the patterns of relationships of major predictors of turnout. And finally, a LISREL analysis is presented that shows that a group focus is as important as a party focus in affecting the level of political alienation pertinent to voter participation.  相似文献
