The relationships of family cohesion and adaptability to adolescent intimacy development were explored by administering the Family Adaptability and Cohesion Evaluation Scales survey and the Fundamental Interpersonal Relationship Orientation — Behavioral Version survey to 207 middle adolescents (70 males and 137 females) from a small midwestern high school. The adolescents' perceptions of family adaptability correlated with the amount of responsibility the teens expressed in their relationships, while cohesion correlated with companionship and affection in their relationships; however, females' scores were related to cohesion, while males' scores were related to satisfaction with cohesion in their families. The study suggests that family cohesion and adaptability differentially influence intimacy development based on the adolescent's gender.Received Ph.D. in marital and family therapy from Purdue University. Research interests include family influences on adolescent development and family issues related to incarceration.Received Ed.D. in human development from Boston University. Research interests include major life transitions (e.g., adolescence, middle adulthood). 相似文献

We conducted a short-term longitudinal study examining the structure of coping behavior and the relationship between coping style and depression during adolescence. The sample consisted of 603 adolescents in Grades 6–11 who were surveyed in the fall of 1989 and again in the fall of 1990. A two-dimensional model of coping was found using confirmatory factor analysis with the factors being approach and avoidant coping. Four cross-sectional and seven longitudinal coping groups were formed to explore group differences in depression. Approach copers reported the fewest symptoms of depression, while avoidant copers reported the most. Subjects who changed over time from approach to avoidant coping evidenced a significant increase in depressive symptoms, whereas subjects who switched from avoidant to approach coping displayed a significant decrease in depression over a one-year period. These findings imply that adolescents who are able to elicit social support, engage in problem solving, and cognitively restructure events within a positive light are more likely to successfully negotiate the challenges of adolescence.This research was supported by a grant from the William T.

Explored the influence of life stress as mediated or moderated by locus of control, family environment, social support, and coping style on psychological adjustment and school performance in 164 ninth graders from Baltimore. Gender differences in findings were shown. For boys, family cohesion was the only variable found to protect against the effects of stress. Family cohesion did not serve protective functions for girls, and along with overall social support, was associated with increased vulnerability to school problems. The report of problem-focused coping strategies exerted a number of protective functions for girls only. External locus of control was found to increase boys' and girls' vulnerability to the effects of life stress. Empirical development of interventions to improve the psychosocial adjustment of inner-city adolescents is discussed.Received Ph.D. from Virginia Polytechnic Institute and State University in 1991.

Abstract: The municipal bond bank (mbb) innovation began in Canada in 1956 and in the United States in 1970. This paper concentrates on why mbbs exist, their characteristics, where they work best, and how they compare with other municipal debt credit enhancement techniques. It concludes with a discussion of the future role these organizations will have in providing long-term capital funding to municipalities in Canada and the United States. Sommaire: Le principe de la Banque d'obligations municipales (BOM) fut introduit en 1956, au Canada et, en 1970, aux États-Unis. Cet article explore la raison d'être des BOMS, leurs caractéristiques, leurs conditions de succés maximum et les compare à d'autres techniques pour rehausser le crédit de la dette municipale. L'article se termine par une discussion sur le rôle que ces organisations auront à l'avenir dam le financement capital à long terme des municipalités au Canada et aux États-Unis. 相似文献

Numerous laboratory experiments have investigated the performance of several processes for providing public goods through voluntary contributions. This research has been able to identify features of the institution or environment which are reliably likely to produce outcomes “close” to the free riding outcome or “substantially” greater than the pessimistic prediction of standard models. One such feature is the “marginal per-capita return” (MPCR) from the public good. Various authors have altered MPCR between groups or for an entire group at the same time. The experiments reported here address a different question, “What would happen if, within a group, some persons faced a ‘high’ MPCR while others faced a ‘low’ MPCR?” 相似文献

This research modeled the extent to which the normative goals of equity and efficiency are embodied in three seminal tax reform proposals (Bradley-Gephardt, Kemp-Kasten, and the Treasury Department proposals) relative to the extant regime. The Tax Reform Act of 1986 (TRA86) is also modeled in the same manner. The objective of this study is to compare the equity and efficiency of the initial proposals with that of the final tax reform law. This before and after analysis is designed to ascertain the degree to which the legislative process undermined the normative goals of the tax reform movement. The National Tax Model was applied to model each regime and to measure the distributional and redistributional effects on tax burdens and wage efficiency costs associated with each system across ten income classes. The reform models, including TRA86, are shown as superior to the pre-reform system with respect to the normative criteria. The legislative process did not substantially compromise the goals as reflected in the seminal reform proposals in the development of a more politically acceptable tax reform law. This exercise demonstrates that it is possible for sound legislation to survive a political process that frequently permits the sacrificing of normative goals in favor of special interests.Financial support provided by the Arthur Young Foundation Tax Research Grant Program and The Ralph E.

Cost control commissions provide two primary types of recommendations: widespread benefits-widespread costs and widespread benefits-narrow costs. Both types of recommendations are not of the form predicted by the standard economic models of political behavior. The paper explores why governors sanction these commissions and the types of recommendations governors will accept. Legislators use the maxim of concentrate benefits-spread costs to maximize votes. Governors, however, face a lower return to concentrated benefit policies and a lower cost from concentrated cost policies. This leads a governor to favor at the margin, policies which have widespread benefit-widespread cost or widespread benefit-concentrated cost. Evidence from 5 state cost control commissions support the difference between the politicians. The cost control commissions sanctioned by governors have proposed recommendations of the widespread benefit-widespread cost and widespread benefit-concentrated cost form. Governors accepted approximately two-thirds of the widespread benefit-concentrated cost proposals, although they were more likely to accept recommendations of the widespread benefit-widespread cost nature. Recommendations which required legislative approval saw a lower likelihood of acceptance. This is consistent with the view that legislators prefer concentrated to widespread benefit recommendations. qu][The politician's] favorite strategy is to create a commission to study a problem and make recommendations that may then be used as political cover. Call it government by commission. 相似文献
