This study tested a model for developmental transitions in defense use in adolescence based on an integration of psychoanalytic views of adolescence and Loevinger's theory of ego development. Loevinger's test for ego development and the Defense Mechanism Inventory were administered to 31 male and 35 female adolescents. Results supported several hypothesized developmental transitions: decrease in aggression outward defenses (e.g., displacement), increase in turning against the self, and an unpredicted increase in defenses entailing reversal (repression, denial, and reaction formation). Results failed to support a hypothesized increase in intellectualization and a decrease in projection. Results supported ego development over chronological age as a more valid index of maturity to apply to the investigation of the development of defenses. Implications of these findings are discussed and directions for future research are suggested.This research was partially funded by the Psychology Department at Boston UniversityAffiliations at the time when this study was conducted were Department of Psychology, Boston University, and Departments of Psychiatry at Beth Israel and McLean Hospitals/Harvard Medical School. Now Clinical Psychologist, Outpatient Psychiatry Service, Baystate Medical Center, Springfield, Massachusetts. Received Ph.D. in clinical psychology from Boston University. Research interests include ego defenses, psychotherapy research, gender, and sex roles.  相似文献

Over the past decade, there has been an explosion of litigation addressing an employer's right to unilaterally amend or terminate medical benefits provided to retirees. The sheer volume of these cases and the variety of facts and legal theories have combined to obscure the patterns and trends that actually are emerging from this litigation. This article will describe the context of the struggle over retiree benefits and discuss those leading decisions in which the federal courts of appeals have established their rules for deciding retiree benefits cases.  相似文献

Conclusion Whilst Lord Templeman seemed satisfied with the result of the decision in thePrudential case, Lord Browne-Wilkinson did not share his view. He said that the outcome of the case was unsatisfactory and did not accord with the agreement of the parties. He said No one has produced any satisfactory rationale for the genesis of this rule. No one has been able to point to any useful purpose that it serves at the present day and he urged the Law Commission to examine whether the rule should continue to operate in English law.The genesis of the rule was, it seems, satisfactorily described by Lord Templeman and its usefulness lies in the fact that it imposes a degree of certainty and reliability on the parties. Each knows from the outset what they have contracted for. Its failing lies in the fact that its operation, as Russell L.J. rightly pointed out, leads to a freely negotiated bargain being defeated. If the Law Commission does examine the rule then clearly the central issue will be the balancing of these two principles and which is to be given effect to. If the law wishes to see certainty and reliability in this area, then Lord Templeman's decision is undoubtedly welcome since the law was clearly in a state of flux and confusion before the case.  相似文献

An increase in birth rates to Minneapolis minors following the enactment of a parental notification law was examined. A well-publicized link between increasing birth rates and the law is shown to have been premature. Birth, abortion, and population data by age, race, and region suggest that the increasing birth rate in Minneapolis was not related to parental notification, but rather to a growing racial minority population.Preparation of this article was supported in part by an Aldeen Grant from Wheaton College. The authors wish to thank the Minnesota Center for Health Statistics, particularly James Wigginton and Carol Vargas, for their considerable work to provide birth, abortion, and population data in a form suitable for the current analysis. The authors also thank Americans United for Life for purchasing the data and providing them to the authors.  相似文献
