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

An assessment of the stress of junior high/middle school (JH/MS) can be made by comparing overall behavior and academic student patterns in JH/MS with those in elementary school (ES), and by evaluating the differential educational consequences experienced by JH/MS students who had varying degrees of maladjustment in ES. Specific numeric data indicate that the environment is far more open, combative, frightening, impersonal, and academically taxing in JH/MS than in the ES. Partly as a result, suspensions, unexcused absenteeism, and grade failure occur at a much greater overall rate in JH/MS. Also, the immediate aftermath of these school adversities is significantly more deleterious in JH/MS than in ES. An analysis of the differential outcome data reveals that JH/MS students who had prominent ES maladjustments have a 5–13-fold greater rate of grade failure, suspension, and undue absenteeism than do students without such ES difficulties, and that generally students without major ES malajustment patterns continue to perform well after their entry to secondary school. In effect, then, JH/MS is primarily a stressful environment for students who are vulnerable on entry.Reveived M. D. from University of Wisconsin. Research interests include school mental health, hyperactivity, and psychopharmacology. 相似文献

Abstract. One of the main ingredients in discourse about British politics concerns the extent to which, and under what conditions, central government can get its own way. Since 1979, the country has been ruled by a prime minister and a government placing at least rhetorical emphasis on the 'politics of conviction'. At the same time we have a well established academic literature giving emphasis to the various hurdles in the policy-making process which face even a government with a working parliamentary majority. The purpose of this paper is to trace the steps in the process towards the government achieving one of its manifesto commitments; the sale of 51 per cent of British Telecom shares to the private sector. In so doing, it is intended to analyse this example of the policy process in terms of the predominant British policy style. 相似文献
