This study examines the nature of adolescent attachment to parents and peers during adolescence. A projective measure was used to classify 99 11th and 12th grade students into secure, insecure dismissing, and insecure preoccupied attachment groups. Respondents identified their primary attachment figure by nomination and by rating the level of attachment support they received from mothers, fathers, best friends, and boy/girlfriends. On average, parents and peers were equally likely to be identified as primary attachment figures but individual preference was strongly tied to attachment style. Secure adolescents significantly favored mothers over best friends, boy/girlfriends, and fathers. Although secure adolescents with romantic partners rated mothers lower on attachment support, none of the adolescents from this group nominated a boy/girlfriend as their primary attachment figure. In contrast insecure adolescents indicated a strong preference for boy/girlfriends and best friends as their primary target for attachment and nearly a third of dismissing adolescents identified themselves as their primary attachment figure. Findings are discussed in terms of individual differences in attachment during adolescence.  相似文献

The effects of methylphenidate on hospitalized conduct-disordered (CD) adolescents were examined by using teacher ratings of behavior, a measure of classroom learning, and a test of impulsivity. Twenty-two male adolescents with CD, 12–18 years of age, participated in a double-blind, placebo-controlled, within-subject (crossover) design in which each adolescent received three doses of methylphenidate (10 mg, 15 mg, and 20 mg) and a placebo in a randomly assigned, counterbalanced order. Seven of the adolescents had a comorbid diagnosis of attention deficit hyperactivity disorder. Significant overall medication effects were shown on teacher ratings of conduct, and on number of arithmetic questions correctly completed and time spent. Within the limitations of this study, stimulant actions may be effective for some aspects of CD in the absence of attention deficit hyperactivity disorder, although only for specific measures.This project was supported by BRSG S 07 RR 05364 awarded to Ronald T.

As part of a 1978 national study of parole, the roles of halfway houses for criminal offenders were examined. It was found that the number of halfway houses began to expand rapidly in the 1960s, and that both services and types of clientele proliferated in the 1970s. Three underlying assumptions of halfway houses were examined, and a topology of houses was developed. It was concluded that halfway houses may be as effective as any other parole program and strategy and may be more cost effective at this time. Future research should further clarify and expand on types of houses and their treatment modalities, linking treatment outcomes to recidivism and reintegration, as well as on including more adequate comparison groups.  相似文献

By examining data from fifteen Latin American nations on several agricultural- and food-related variables for 1965 to 1977, this paper analyzes the efficacy of the Green Revolution for food consumption. A Radical Model is offered to explain why a high technology, export-oriented, agricultural policy may not adequately serve the food consumption needs of Third World countries.  相似文献
