Since 1990, the German government has been demanding from the civil servants of the former East Germany a new adaptability and creativity that was never promoted in the GDR bureaucracy. The article analyses the change of ethics in the former East Germany after 1990. It looks at the development of the German civil service, discusses the economic disparity between East and West, and examines the ethical tradition in the former socialist country. It uses the case of the selection in 2001 of the city of Leipzig by BMW as the location of a new manufacturing plant as an illustration of the new goal‐oriented activities of the present Eastern bureaucracy. More than 250 European cities were competing for the new plant, which will create over 10,000 jobs. The level of performance of the Leipzig bureaucracy in the BMW case reveals the new efficiency and professionalism of the former Eastern civil service. In addition to Leipzig, virtually all the local and state administrations from the former East Germany have developed a sense of the necessities of the time, including globalization.

It also identifies important trends in commerce affecting intermodal freight generation. It concludes with a discussion of issues facing intermodal freight transportation planning and policy making at the millennium.  相似文献

Data from a sample of young adolescents between the ages of 10 and 12 years (N = 898) from the mother–child data set of the National Longitudinal Survey of Youth were analyzed in a study of influences that explain the relation between poverty and depressive symptoms measured 2 years later. Other variables that predicted youth depressive symptoms were also identified. Results indicated that neighborhood problems, nonparticipation in outside school and neighborhood activities, residing with mothers who exhibited depressive symptoms, and mother's use of physical punishment were partial mediators of the effect of poverty on depressive symptoms 2 years later. Youth health status, lower levels of school satisfaction, marital-partner conflict, and father's emotional support also predicted depressive symptoms. The findings indicate that youth depressive symptoms are multiply determined and that poverty can adversely affect young adolescents in many ways.  相似文献

This study used a cluster analytic approach to identify self-esteem trajectories among adolescents over a four-year period from sixth to tenth grades (N = 1,160). Four self-esteem trajectories were identified that replicated previous research: (1) consistently high, (2) moderate and rising, (3) steadily decreasing, and (4) consistently low. Female adolescents were more likely to be in the steadily decreasing self-esteem group while male adolescents were more likely to be in the moderate and rising group. African American and white youth were equally distributed across groups. Using repeated measures analysis, we found that youth with consistently high and moderate and rising self-esteem reported developmentally healthier outcomes in Grade 10 than youth in the other two clusters. Outcomes included susceptibility to peer pressure, school grades, and alcohol use. Implications of these results for studying self-esteem and developmental change more generally are discussed.  相似文献

Our purpose is to provide empirical evidence of the relations between the quality of governmental audit services and auditor tenure and between quality and fixed fee audit contracts. Audit quality is assessed by Offices of Regional Inspectors General and is based on a review of the audit reports and supporting working papers. We test a model of quality supplied on a sample of audit engagements selected from a population of audited federal assistance programs. The empirical analysis finds that the probability of receiving a substandard audit increases with the length of the auditor-client relationship. Our analysis finds a positive relation between fixed fee contracts and the incidence of violations of professional standards among audits of federal assistance programs. Additionally, we provide evidence that the incidence of noncom-pliance with professional standards is significantly lower when the audit contract contains a provision for administrative and/or legal remedies in the event of substandard performance.  相似文献

This paper develops the concept of institutional social capital and discusses its importance in the labor market. Institutional social capital is constituted by the resources inherent in an organization (such as a school) and thereby available to members of that organization. This is contrasted with the social capital available to individuals through their own personal networks. In the labor market context, an example of institutional social capital is the ties that schools have with employers who recruit a proportion of their new employees as they prepare to graduate. The paper examines how these ties and the norms governing the important labor market screening role played by the high school developed in post-WWII Japan. I also discuss an important positive externality – social control over students – generated by schools institutional social capital. Finally, I examine current challenges to Japanese high schools institutional social capital.  相似文献
