This paper has attempted to test the applicability of the Public Choice approach in explaining regulation in the Indian Sugar Industry over the 1967–82 period. A test for discriminating between Public Interest and Capture theories of regulation was developed and implemented in the context of the historical pattern of controls found in the Indian Sugar Industry. The results point toward the rejection of the Public Interest theory of regulation and are consistent with the hypothesis of the capture of regulation by the regulated industry. The importance of the various interest groups and their influence on the regulation actually enacted was also revealed by the analysis.The findings are consistent with the existence of substantial rent-seeking and other D.U.P. activity (Bhagwati, 1982) in the Indian sugar sector during the post-independence period. They point toward the substantial welfare losses suffered by consumers and the economy at large as a result of the control regime that has existed in the Indian sugar sector. Removal of such controls will more than likely increase the availability of sugar at lower prices thus increasing the welfare of consumers while reducing the extent of corruption and other rent-seeking activity that the controls have generated.  相似文献

The decline in sports participation that begins in early adolescence has been well documented, and there has been considerable controversy regarding the reasons for this attrition. The present study addressed the attrition process by focusing on the subjective experience of sports as a function of grade, gender, and sport context. Following the procedures of the Experience Sampling Method, 401 5th–9th-grade boys and girls carried electronic pagers, similar to those worn by doctors, for one week, and filled out self-report forms on their activities and subjective states in response to signals received at random times. Older respondents spent less time in sports than their younger peers. This age difference was due primarily to a decline in informal sports participation, with less pronounced attrition from organized sports. Our findings suggest that the reasons for attrition from sport may be context specific. While informal sports were experienced more positively than gym class or organized sports, perceptions of skill were lowest during informal sports and declined with age. It seems youngsters stop participating in organized sports because these activities are less enjoyable to them, while attrition from informal sports is more performance based. Boys spent more time in sports than girls, and this difference was based primarily upon significant gender differences in informal sports participation. In spite of their differential rates of participation, boys and girls reported similar levels of affect, arousal, and skill during sports.This research was supported by NIMH grant number MH38324, Stress in Daily Life During Early Adolescence, awarded to Reed Larson, and was carried out while the first author was a Dissertation Fellow in the Department of Psychology at Loyola University of Chicago.Received Ph.D. in psychology from Loyola University of Chicago.

The present study identified variables that discriminated bulimic (N=71) from nonbulimic (N=71) adolescent females within a high school setting. A discriminant function analysis identified six variables that significantly differentiated these two groups. These variables included disturbed eating attitudes, negative perceptions of weight and body image, depressive symptomatology, and alcohol use. Post hoct tests indicated that, compared to the nonbulimic girls, the bulimic adolescents were significantly more depressed, viewed themselves as significantly more overweight, used alcohol significantly more frequently, possessed significantly more disturbed eating attitudes, had a significantly greater discrepancy between their current and ideal weight, and felt it was significantly more important to achieve this ideal weight. The implications of these findings for the etiology and early identification of bulimia in adolescence are discussed.Received Ph.D. from Kent State University. Research interest is applied clinical research.Received Ph.D. from University of Vermont. Research interest is behavioral medicine.  相似文献

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.

Data from a large sample of late adolescents was used to examine associations between family relationships (reported closeness to parents and siblings) and perceived social competence. Significant positive relationships were found between family bonds and the social competence measures, which included social self-esteem, instrumentality, expressiveness, shyness, and degree of satisfaction/ease in same- and opposite-sex peer relationships. There was no evidence of differential effects of sibling versus parent relationships upon adolescent social competence.This project was supported by NIMH Grant 5 R01 MH34570.Received Ph.D. from Northwestern University.  相似文献
