The premise that effects of maturational timing are mediated by social context is explored by comparing adolescent girls in dance and nondance schools. Because the dance student must maintain a relatively low body weight, being a late maturer (who is often leaner than an on-time maturer) is expected to be more advantageous to the dancer than to the student not required to meet a weight standard. Girls aged 14 to 18 were seen; 276 attended private schools and 69 attended national ballet company schools. AllSs were weighed and measured and asked questions about their secondary sexual development, weight-related concerns, eating concerns, adult sex-role expectancies, body image, emotional functioning, and family relationships. Menarcheal age was used to classify girls as early (before 11.5 years of age), on time (between 11.5 and 14 years), and late maturers (after 14 years). More dance than non-dance school students were late maturers (55% versus 29%). The dance students weighed less and were leaner, had higher eating scores, and had lower family relationship and impulse control scores than the comparison sample. Across groups, late maturing students weighed less, were leaner, and had lower diet and higher oral control scores than on-time maturers, with the differences more pronounced in the dance than nondance students. In addition, the on-time dancers had higher psychopathology, perfection, and bulimia scores and lower body image scores than the late maturing dancers. The findings are discussed in terms of a goodness of fit between the requirements of a social context and a person's physical and behavioral characteristics.This paper was prepared with the support of grants from the W.

The present investigation attempted to ascertain longitudinally whether diffuseness about academic goals and plans would predict subsequent underachievement. Identity-status interviews were administered to 98 firstsemester college students. Their grade point averages (GPA) were obtained for their first six semesters in college. SAT and conceptual-level scores were used to generate predicted GPAs. Underachievement was operationally defined as a positive discrepancy between predicted-minus-observed GPA: underachievement=predicted observed GPA. Evidence for the hypothesized relationship between diffusion and academic underachievement was not found. To the contrary, Diffusions during their freshman year showed a tendency for relativeoverachievement (predicted observed GPA). The possibility of heterogeneity within Marcia's diffusion status was considered. Some diffuselike individuals may see their current lack of commitment and concern as a hiatus, whereas others may be truly unconcerned and myopic about their lives. A significant association between foreclosure and underachievement was found when the subjects were freshmen. This relationship was not replicated with an independent sample of 90 high school students. A post hoc interpretation focused on differences between transient and long-term Foreclosures and the role that the college environment may potentially play in instigating personal identity crises. The need for longitudinal tests on this account is underscored. 相似文献

This study investigated the effects of family structure (parents together or not) and parental discord (ratings of the happiness of the marriage of biological parents) on the self-esteem of 199 female undergraduates. Family structure and happiness ratings were substantially related, with those separated rated as less happy. Self-esteem was significantly related to parental happiness, even with family structure controlled, but not to family structure with parental happiness controlled. With the sample divided into three groups (happy-together, unhappy-together, and separated) ANOVA showed a significant effect for group, with the unhappy-together group showing significantly lower self-esteem than the happy-together group, and the separated group intermediate. Parental discord thus appears to lower the selfesteem of daughters, whereas separation of parents does not. These findings support Heatherington's idea that children may be better off in a stable family where parents are divorced than in an intact family with much parental discord.Thanks are expressed to Susan Stevenson Cowles for her contributions to all stages of the study, and to Judith Fidati, Anita Katz, and Susanne Long for their assistance in the scoring and statistical analyses. The author is also grateful to Andrew Cherlin, Edmund Henderson, and Ruth C. Wylie for their helpful suggestions.Barbara H.

Adolescents' understanding of societal conflict and of compromise resolution in the context of peer and authority relations was investigated. Six conflict stories were prepared for three social issues. Each issue included two similar stories that were counterbalanced for presentation in peer or authority context. The adolescents—ages 11, 13, 15, and 17—were asked to develop dialogues by continuing conversations from the stories with the aim of resolving the conflict. Responses were categorized on a 3-point scale: (1) noncompromise, (2) routine compromise, and (3) constructive compromise. In addition, one moral and one political dilemma were presented in order to relate conflict resolution to moral and political development. The major findings were an increase in frequency of constructive compromise with age and in peer vs authority context. Further, both moral and political development were significantly related to conflict resolution scores in peer but not in authority context. Results corroborate an interpretation that considers peer communicative relations of mutual respect and cooperation as a primary path to mature stages of social reasoning.Received Ph.D. in 1986 from Catholic University of America.

When Congress delegates a policy mandate to a regulatory agency, Congress acts as a principal, choosing the institutional arrangements, or the ‘rules of the game’ for agency decision making. Individuals in the agency, acting as agents, take the rules of the game as given and do the best they can within these institutional arrangements. In this paper we develop a simple model that relates the congressional choice of institutional arrangements to two underlying environmental factors — uncertainty and conflict. We suggest that uncertainty and conflict of interest lead Congress, in delegating, to prescribe a greater scope of permissable regulatory activity, a wider array of regulatory instruments, and more confining regulatory procedures. Increased scope and stronger instruments tend to broaden the overall discretionary authority of the agency, while more confining procedures tend to narrow it. We conjecture that with increased uncertainty or conflict the narrowing tendency more than offsets the broadening tendency, for a net decrease in the agency's overall discretionary authority. Lastly, we argue that the performance of a regulatory agency in fulfilling its mandate is determined in large measure by the foundations Congress constructs for the implementation of delegated authority. 相似文献
