There are two categories of income distribution evaluations: first, the more-or-less “value-free” perception of income inequality as a statistical dispersion; and second, the valuation of income distributions according to an explicit social welfare function which is meant to capture all of society's value judgements. These societal value judgements can be expressed in the form of preferences. Whereas the inequality perception of income distributions appeals to an observer's sober judgement, the revelation of preferences with respect to specific income distributions appeals to his or her sentiments. This paper is an empirical analysis which investigates the juxtaposition of preferences with respect to income distributions and corresponding perceptions of distributional inequality. We do this through a questionnaire in which attitudes towards various distributional axioms are tested. The source of our data is 1773 completed questionnaires collected from five German universities. Based on our data, we observe that individuals' preference orderings over the set of income distributionssubstantially deviate from their perceptions of distributional inequality. In fact, our test responses showed that even when some income distribution is judged to be more unequal than another, that distribution might be preferred, as it accords higher incomes to each individual. We hold that the preference for these greater incomes expresses a compensation for the increased degree of inequality. This explanation applies both to equiproportional and to equal fixed-sum increases in incomes, which implies a support of Paretian ethics.  相似文献

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.

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.
