The primary aim of this paper is to review the literature on preadolescent friendships in order to examine the relationship between preadolescent friendships and social support in adulthood. Social supports are important to health, both directly and as a stress buffer. Few studies, however, have specifically examined adult social supports from the perspective of their developmental precursors and critical developmental periods. Some data indicate that the preadolescent period may be of particular importance to the development of adult social skills and ties. Observational and empirical studies of preadolescent peer relationships, and in particular best friendships, suggest unique and critical contributions to adult social relatedness. Present research is suggestive but is insufficient to validate preadolescence as a critical period in adult social relatedness. Our review has implications for better understanding the mechanisms by which preadolescent friendships effect adult social support—an important mediator of the effects of stress on health. Further longitudinal study is needed.Received Ph.D. from University of Maryland.

Since the 1990s there has been a long-standing concern in government towards public sector accountability, management, efficiency and service delivery. A number of studies have attempted to analyse the multitude of individual changes and their manifestations through analyses based on a variety of institutional, policy and governmental distinctions. This paper attempts to specify the changes with particular reference to planning, and to consider the evolution of the public service ethic in planning towards more openness, scrutiny, transparency and efficiency with particular reference to the changing ethos of the professional employee. We first explore the main impacts upon local government, the public service ethic and professional planning as a consequence of the Modernization agenda and freedoms and flexibilities initiative. We then look at how such changes have impacted upon the ethos and values in public service and planning. We draw on some evidence of Ombudsman cases to highlight issues of professional values in planning practice over the past decade before finally drawing these strands together in some conclusions. Our principal findings indicate that the much-trumpeted decline of services and standards may not have been as apparent as is sometimes portrayed and that internal professional attitudes and values towards the external changes may not have significantly altered over the same period. 相似文献

Workers Compensation claims are not interpersonal disputes. Almost always they are disputes between individuals and corporations. Compensation insurers are "repeat players" in the system. Workers are often "one–shotters" who have little or infrequent contact with the system. Power inequality between the worker, employer, insurer, and those who are required to facilitate negotiations and resolve and settle disputes under compensation legislation are matters of considerable importance. This paper examines the effects of the implementation, in 1993, of informal dispute resolution processes in the Western Australian workers compensation system under the Workers Compensation and Rehabilitation Act 1981(WA), which excluded lawyers from the process. It argues that preexisting power imbalances have been aggravated by these procedural changes, and in particular, by the exclusion of legal practitioners from the dispute resolution process. The issues raised herein have general application to most workers compensation systems. 相似文献
