This study examined the association between youths' triangulation in marital conflict and three aspects of their peer relations in 416 families during early adolescence. A 4‐wave, longitudinal research design was used. As hypothesized, triangulation was associated negatively with perceived support from friends and positively with perceived peer rejection. Triangulation was a risk factor for both sons and daughters. Adolescent problem behavior did not mediate the significant association between triangulation and perceived friendship support. Adolescent problem behavior, particularly internalizing problems, completely me diated the association between triangulation and adolescents' perceptions of peer rejection, suggesting the important developmental role of adolescents' anxiety, depressive affect, and withdrawal. The implications of these findings are discussed in terms of Bowen's multigenerational family systems theory and social learning principles.  相似文献

Abstract

Bachelor of Social Work (BSW) curriculum design is generally considered a collaborative process involving educators, students, practitioners, and employers. The social agency contributes in critical economic, pedagogical, and political ways. The literature is ambiguous, however, regarding compatibility of educators' and practitioners' views on curricula, homogeneity of perceived training needs, and societal changes necessitating curriculum revision. In this study, 77 agency personnel reported their views of 56 BSW curriculum items. The development of communication competence, the mastery of content on socialization and the small group, and the cultivation of basic social work values were commonly viewed as essential. BSW program directors, graduates, and potential employers generally had compatible views. Practice conditions—especially service position (direct or indirect), field of practice, and client age group—influenced curriculum priorities. Changes in educational priorities across a decade were minor, with increasing emphasis on ethical practice, especially as related to confidentiality.  相似文献

This article examines the representation of Black women's weight in contemporary diet advertising and African American film. It positions socioeconomic class as a significant factor that distinguishes between “good” weight and “bad” weight. I argue that there is a distinction to be made between representations of poor and working-class fat Black women and middle-class fat Black women. The increased presence of Black women as diet spokeswomen is also questioned. The social construction and filmic representation of the African American cuisine “Soul Food” and the political economic notion of neoliberalism are used as frameworks to deconstruct how notions of self-discipline, personal responsibility, and citizenship impact upon Black women's bodies. As a case study, I examine the careers of Oprah Winfrey and Gabourey Sidibe and the ways in which their weight has been differently coded based on class, the neoliberal rhetoric of “personal responsibility,” and food. I ultimately critique how contemporary media has helped to shape contemporary discourses on Black women's weight.  相似文献

This note extends the score test statistics for overdispersion in Poisson and binomial regression models (Dean, 1992 Dean , C. B. ( 1992 ). Testing for overdispersion in Poisson and binomial regression models . J. Amer. Statist. Assoc. 87 : 451457 .[Taylor & Francis Online], [Web of Science ®] [Google Scholar]) to the zero-inflated models. Some general results are obtained, and examples illustrate the application of the extended results.  相似文献

Using data from Wave 1 (n = 5,070) and Wave 2 (n = 4,404) of the National Longitudinal Study of Adolescent Health, we examined the relationship between cumulative risk exposure and youth problem behavior. Cross‐sectional analyses revealed a positive, linear association between cumulative risk and problem behaviors. The association between cumulative risk and externalizing problems was stronger for White youth than for Black youth. The association between cumulative risk and internalizing problems was stronger for girls than for boys, and stronger for White youth than for Black and Hispanic youth. Cumulative risk predicted change over time in internalizing problems. Findings support the theoretical notion that adolescents experience diminished psychological comfort when risk factors are present across several social domains.  相似文献

1. Attendance at a 10-week class designed to teach behavioral management strategies to people with schizophrenia was effective in reducing some of the negative characteristics of auditory hallucinations for 12 months and in reducing anxiety for 9 months after completion of the class. 2. The sustained improvement experienced by class participants was characterized by their voices being less frequent and more mumbled and the participants feeling more in control, less distractible, and less anxious. 3. Participants recommended that other mental health consumers take similar classes to learn how to better manage their voices. 4. Monthly support groups may help participants maintain gains lost during the follow-up period.  相似文献

The Andersen-Gill multiplicative intensity(MI) model is well-suited to the analysis of recurrent failuretime data. The fundamental assumption of the MI model is thatthe process M_i(t) for subjects i=1,,n,defined to be the difference between a subject's counting processand compensator, i.e., N_i(t) A_i(t); >0,is a martingale with respect to some filtration. We propose omnibusprocedures for testing this assumption. The methods are basedon transformations of the estimated martingale residual process ^M i (t) a function of consistent estimatesof the log-intensity ratios and the baseline cumulative hazard.Under a correctly specified model, the expected value of ^M i (t)is approximately equal to zero with approximately uncorrelatedincrements. These properties are exploited in the proposed testingprocedures. We examine the effects of censoring and covariateeffects on the operating characteristics of the proposed methodsvia simulation. The procedures are most sensitive to the omissionof a time-varying continuous covariate. We illustrate use ofthe methods in an analysis of data from a clinical trial involvingpatients with chronic granulatomous disease.  相似文献
