Rhodes JE 《New directions for youth development》2004,(101):145-161
After-school settings are interpersonal in nature, and the quality of the relationships that are forged can directly influence youths' attendance decisions and the developmental benefits they derive. Programs should more effectively capitalize on this potential for caring adult-staff relationships. 相似文献

Recurrent events are frequently observed in biomedical studies, and often more than one type of event is of interest. Follow-up time may be censored due to loss to follow-up or administrative censoring. We propose a class of semi-parametric marginal means/rates models, with a general relative risk form, for assessing the effect of covariates on the censored event processes of interest. We formulate estimating equations for the model parameters, and examine asymptotic properties of the parameter estimators. Finite sample properties of the regression coefficients are examined through simulations. The proposed methods are applied to a retrospective cohort study of risk factors for preschool asthma. 相似文献

Adolescent suicide is increasing in the United States and the incidence of suicide gestures and attempts in juvenile correctional facilities is high. The attitudes of correctional staff toward adolescents and toward suicidal behavior may contribute to the increase. Suicide is often the outcome of a progression of problems that have isolated the adolescent from meaningful social relationships. Correctional staff must be aware of the phenomenon of adolescent suicide and be given training to deal with it effectively within the institution. Institutional staff have commonly seen suicide gestures or attempts as acting out behavior rather than a symptom of low self-esteem or inability to cope with institutional placement. This discussion examines the phenomenon of adolescent suicide and the impact the juvenile justice system has on its occurrence. It will also include an examination of interdisciplinary interventive strategies which can be used in an institutional setting. 相似文献

The regulatory environment is assumed to be characterized by changing labor costs and productivity, and by the existence of set-up costs for rate reviews. If the commission behaves myopically, price changes are shown to occur only when a threshold deviation of actual from target return is reached. During periods where productivity (wage) increases predominate, the actual return is thus consistently higher (lower) than the target level. If, however, the commission incorporates dynamic trends into its decision-making process, there are intervals where actual return both exceeds and falls short of target levels; on average, the firm earns over time a return that is approximately equal to the target level. 相似文献

The implications of retirement for marital and family relationships were explored in golden wedding couples, against a background of those few studies that have so far examined relationships in long-married couples. Older couples can be described in two domains: behavioral and affective. Five activity types are derived from the amount or diversity of shared activities between spouses during a typical day. These types interact with the degree of intimacy measured on two instruments. It was concluded that retirement does not affect intimacy directly, but that it does indirectly through extra time and proximity which provide opportunity for enhancing prevailing intimacy between partners or for magnifying irritations. 相似文献

Undergraduate subjects were seen to accurately discriminate between simulating actors and genuinely disabled males confined to wheelchairs. Judgments were based on skill in manipulating the wheelchair, poorer muscular development of the disabled, and on appearance of clothing. Implications for research on the disabled employing actors was discussed.This study was supported by a grant from the York University Faculty of Arts awarded to the first two authors. The project was performed as the third author's Honours thesis. The authors wish to thank all participants for their cooperation and assistance in making this research possible. The authors also wish to thank Gail Kenyon, Coordinator of the Centre for Handicapped Students who helped recruit participants for the videotaping and to Lucie Cantrell, Executive Officer of the York University Counselling and Development Centre who arranged for the use of the Centre's facilities and equipment. 相似文献
