The aim of the present study was to compare coping styles in delinquent adolescents (n=178) versus matched controls (n=91) from the Arkhangelsk region in Northern Russia and to test for possible interrelations with personality traits and parental rearing factors. The samples were assessed by means of the Coping Scale for Children and Youth (CSCY), the Temperament and Character Inventory (TCI), and the EMBU questionnaire on parental rearing. The delinquents differed significantly from the controls on most aspects of the coping styles under investigation. Furthermore, some specific correlational patterns between coping styles and both personality dimensions and parental rearing factors emerged. The findings are discussed in the light of the interactive nature of relations between personality and parental rearing in the development of coping styles.  相似文献

This article examines the issues involved in federal investment budgeting and planning for the acquisition of federally-owned assets. It describes the unique role of the federal government and examines the different issues and reforms prompted by differing types of capital and investment sponsored at the federal level. It suggests that meaningful changes can be instituted in our budgeting practices that can make a difference for our budgetary choices without adopting a full-scale capital budget. It also presents a framework for improving federal agency capital decision making based on a study of practices used by leading state and local and private sector organizations. The article is based on testimony delivered before the President's Commission to Study Capital Budgeting.  相似文献

The belief that minimum-wage legislation helps the working poor is one reason for its continued popular support. The authors track the household incomes of low-wage workers and find that a radical transformation has occurred in the half century since the passage of the original minimum-wage law. Today most low-wage workers live in households well above the poverty line. Hence, those living in poverty will get only about 11 percent of the gains from the higher minimum-wage increase proposed in the Kennedy-Hawkins Bill. Low-wage workers in families with incomes three or more times the poverty line will get nearly 40 percent. Thus it is not clear that increases in the minimum wage make good policy even if no jobs are lost as a result.  相似文献

This article evaluates the feasibility of performing natural resource damage assessments under the current Superfund legislation. Using the analyses developed for two recent cases, it explains the sources of the substantial divergences between plaintiffs' and defendants' estimates of these damages. Three factors explain the differences in damage estimates: (1) the time horizon used and treatment of capitalization effects of past damages; (2) the extent of the market assumed in estimating the effects of a release of hazardous wastes on the demand for the affected natural resource; and (3) the character and availability of substitutes for the resource involved.  相似文献
