This prospective study examined the usefulness of seven selected variables from Jessor and Jessor's problem behavior theory in predicting the future smoking levels of adolescent experimental smokers. Experimental smokers were identified through a survey of 2,550 seventh- and eighth-grade students assessing subjects' current smoking levels as well as subjects' responses to the selected variables. Twelve months later the entire sample was resurveyed to assess subsequent smoking levels of subjects initially reporting experimental smoking. Experimental smokers who responded to both surveys (n=225) were subjects of the present study. The full model discriminant function was significant in discriminating between the two groups; 68% of the subjects were correctly classified. This moderately successful hit rate was 24% better than what could be expected by chance. Increased smokers had lower expectations for academic achievement, had stronger beliefs about the positive functions of smoking, and perceived more smoking among their classmates and close friends. Educational interventions are suggested.Received Ph.D. from the University of Nebraska in 1987.

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

This paper examines whether severity of depression reduces or intensifies the relationship between friends’ suicide attempt and adolescent's own attempt to commit suicide, and whether there are gender differences in this interrelationship. Using logistic regression and data from a nationally representative sample of adolescents studied at 2 points in time, this study yielded significant findings. First, friends’ suicide attempt and adolescent depression each predicts adolescent's own attempt to commit suicide, and these effects are similar for both boys and girls. Second, highly depressed adolescents are less likely than low- or nondepressed adolescents to attempt suicide when their friends attempt suicide, and this relationship is observed mainly among adolescent boys. Finally, for adolescent girls, depression reduces the relationship between friends’ suicidal attempt and adolescent's own attempt but this effect is not statistically significant. These results are discussed in light of their theoretical importance and policy implications.Professor of Sociology at San Diego State University.

A synthesis of rights and participatory approaches to citizenship, linked through the notion of human agency, is proposed as the basis for a feminist theory of citizenship. Such a theory has to address citizenship's exclusionary power in relation to both nation-state ‘outsiders’ and ‘insiders’. With regard to the former, the article argues that a feminist theory and politics of citizenship must embrace an internationalist agenda. With regard to the latter, it offers the concept of a ‘differentiated universalism’ as an attempt to reconcile the universalism which lies at the heart of citizenship with the demands of a politics of difference. Embracing also the reconstruction of the public-private dichotomy, citizenship, reconceptualized in this way, can, it is argued, provide us with an important theoretical and political tool.  相似文献
