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.

The relationships of family cohesion and adaptability to adolescent intimacy development were explored by administering the Family Adaptability and Cohesion Evaluation Scales survey and the Fundamental Interpersonal Relationship Orientation — Behavioral Version survey to 207 middle adolescents (70 males and 137 females) from a small midwestern high school. The adolescents' perceptions of family adaptability correlated with the amount of responsibility the teens expressed in their relationships, while cohesion correlated with companionship and affection in their relationships; however, females' scores were related to cohesion, while males' scores were related to satisfaction with cohesion in their families. The study suggests that family cohesion and adaptability differentially influence intimacy development based on the adolescent's gender.Received Ph.D. in marital and family therapy from Purdue University. Research interests include family influences on adolescent development and family issues related to incarceration.Received Ed.D. in human development from Boston University. Research interests include major life transitions (e.g., adolescence, middle adulthood). 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. Research interests: adult children of alcoholics and human sexual behavior.Received Ph.D. from West Virginia University. Research interests: the impact of popular culture on adolescents and the impact of parental conflict on children.Received Ph.D. from University of Massachusetts.

This research modeled the extent to which the normative goals of equity and efficiency are embodied in three seminal tax reform proposals (Bradley-Gephardt, Kemp-Kasten, and the Treasury Department proposals) relative to the extant regime. The Tax Reform Act of 1986 (TRA86) is also modeled in the same manner. The objective of this study is to compare the equity and efficiency of the initial proposals with that of the final tax reform law. This before and after analysis is designed to ascertain the degree to which the legislative process undermined the normative goals of the tax reform movement. The National Tax Model was applied to model each regime and to measure the distributional and redistributional effects on tax burdens and wage efficiency costs associated with each system across ten income classes. The reform models, including TRA86, are shown as superior to the pre-reform system with respect to the normative criteria. The legislative process did not substantially compromise the goals as reflected in the seminal reform proposals in the development of a more politically acceptable tax reform law. This exercise demonstrates that it is possible for sound legislation to survive a political process that frequently permits the sacrificing of normative goals in favor of special interests.Financial support provided by the Arthur Young Foundation Tax Research Grant Program and The Ralph E.
