Using data from a probability sample of 4,987 adolescents, we examine the degree to which closeness to mother, closeness to father, parental support, and parental monitoring buffer the relationship between peer drug use and adolescent marijuana use. The relationship between peer drug use and adolescent marijuana use was attenuated by both closeness to father and the perception that parents would catch them for major rule violations. These findings confirm the value of conceptualizing certain family characteristics as separate variables and verify that authoritative parenting may help insulate adolescents from peer pressure to use drugs. 相似文献

This paper describes a longitudinal study evaluating organizational changes at a postal sorting terminal in Sweden. One hundred postal workers were followed up for 1 year after the changes were put in place. Information about psychosocial factors, sleep disturbances and gastrointestinal complaints were collected by questionnaires administered at the onset of the changes and at 8 and 12 months later. Sick leave during the 1-year follow up was compared with that during the year before the changes were introduced. A significant increase in skill discretion and in authority over decisions occurred during the study period. The reported increase in skill discretion and authority over decisions correlated with a reduction in difficulties with sleep and with gastrointestinal complaints. Changes in reported contact with team mates and superiors also correlated with changes in the reporting of sleep difficulties and gastrointestinal complaints. There was a significant reduction in sick leave. The results indicate that the organizational changes improved the quality of work and at the same time reduced sick leave and psychosomatic complaints. 相似文献

Self‐Mutilation and Homeless Youth: The Role of Family Abuse,Street Experiences,and Mental Disorders
Kimberly A. Tyler Les B. Whitbeck Dan R. Hoyt Kurt D. Johnson 《Journal of research on adolescence》2003,13(4):457-474
Self‐mutilation, which is the act of deliberately harming oneself, has been overlooked in studies of homeless and runaway youth. Given their high rates of abuse and mental health disorders, which are associated with self‐mutilation, homeless and runaway youth provide an ideal sample in which to investigate factors associated with self‐mutilation among a nonclinical population. Based on interviews with 428 homeless and runaway youth aged 16 to 19 years in 4 Midwestern states, the current study revealed widespread prevalence of self‐mutilation among these young people. Multivariate analyses indicated that sexual abuse, ever having stayed on the street, deviant subsistence strategies, and meeting diagnostic criteria for depression were positively associated with self‐mutilation. The findings are interpreted using stress theory and affect‐regulation models. 相似文献

Mead's rarely explored notion of an “objective reality of perspectives” serves as a point of departure for a discussion of the implications of his work for general sociological theory and the analysis of contemporary societies. The epistemological background is explored to the point where sociology can be viewed as pragmatist mode of response to the inevitable relativity of knowledge. Mead's well known theory of identity formation plays an essential role in this context. The concept of perspective may serve as bridge for a generalization of the notion of identity in order to demonstrate the genuine sociological character of Mead's work. Illustrations are provided of the potential inherent in Mead's thought for research and to the study of contemporary societies. Finally sociology itself is conceived as a special kind of perspective, concerned with the inevitable perspectivity of human behavior. 相似文献

According to the conventional wisdom, political parties are hurt by unaffiliated voters (those who are not registered as Democrats or Republicans). These independents are irresponsible and unpredictable. Recent election law reforms throughout the country have encouraged affiliation by restricting voting in a primary to party members. This study examines the effect of the closed primary system in Connecticut. Research found that since the advent of the primary, the proportion of voters registered as unaffiliated has undergone a steady decline. But the decline in the proportion unaffiliated, however, does not appear to have strengthened partisan commitments. Rather it has changed the meaning of unaffiliated registration. In the past unaffiliated voters tended to be Democrats. Today they are equally likely to be either party. 相似文献

The problem of characterizing an exponential family by sufficiency of certain statistics is considered. In distinction to most of the papers on this subject we do not want to characterize an exponential family of order less than or equal to k by the existence of a-dimensional sufficient statis tics in.GepenoenX' oi inc sample size. Since such a characterization is only valid under regularity assumptions, which is shown in the paper, we consider a stronger property of an exponential family which turns out to be a characteristic one. At this the concept of generalized likelihood functions will play an important role. 相似文献
