Research on the mechanisms by which interparental conflict (IPC) affects child depression suggests that both parenting and children’s conflict appraisals play important roles, but few studies have explored the role of general cognitive style or included both parenting and cognitions in the same design. Moreover, the effects of IPC on minority children are not well understood. In this longitudinal study, parenting was examined as a mediator of the relation between increasing IPC and change in depression. General cognitive style was included as a moderator. The combined influence of parenting and cognitions was also explored. A racially and ethnically diverse sample of 88 fifth and sixth graders from two urban schools reported their cognitive style, depressive symptoms, and perceptions of conflict and parenting at two time points separated by one year. Parental warmth/rejection mediated the relation between IPC and depression, and general cognitive style acted as a moderator. Parenting, cognitive style, and IPC did not significantly interact to predict change in depression over time. Findings indicate that both parenting and children’s general cognitive style play a role in understanding the impact of increasing IPC on children’s well-being.  相似文献

The National Oceanic and Atmospheric Administration instituted a Planning, Programming, Budgeting, and Execution System (PPBES) in 2002. As supplemented by matrix management, PPBES was appealing as an effort to rationalize the performance of an agency with an especially high degree of functional overlap among its component parts. Although PPBES has had some salutary effects, the agency's experience to date consistent with accounts of the difficulties that led to the abandonment of program budgeting by the civilian bureaucracy almost 40 years ago. As such, it speaks to the limits of performance assessment as a means of reallocating resources and responsibilities across organizational boundaries.  相似文献

This paper examines the federal government's success in implementing and providing high-quality service through e-government, something that has received very little attention. We define quality from the perspective of the end users of federal agency Web sites, as measured through customer survey data. Using data from the American Customer Satisfaction Index, we compare the performance of federal agency Web sites across a range of relevant variables with a private sector equivalent, e-business Web sites. Our findings suggest that federal e-government Web sites are not yet, in the aggregate, providing the same level of quality as their e-business counterparts. We also find significant variability among federal agencies. We discuss the implications of these findings for e-government performance measurement, performance benchmarking, and the market-centered theories of administrative reform that are driving e-government and similar transformations of government practice.  相似文献

In this study, we consider the efficacy of a relatively new and widely accepted certification system for teachers established by the National Board for Professional Teaching Standards (NBPTS). We utilize an extensive database covering the universe of teachers and students in Florida for a four‐year span to determine the relationship between NBPTS certification and the impact of teachers on student test scores from both low‐stakes and high‐stakes exams. Contrary to some previous studies, we find evidence that NBPTS certification provides a positive signal of a teacher's contribution to student achievement only in a few isolated cases. However, our results do reinforce evidence from previous research that the process of becoming NBPTS certified does not increase teacher productivity. © 2009 by the Association for Public Policy Analysis and Management.  相似文献

This article takes a state's eye view of trends towards a more centralised system of governance in Australia. It argues that while globalisation strengthens the roles of national governments it also provides less noticed public policy and management opportunities for sub-national governments. The article shows how state governments in Australia can use high-level policy proposals to reinforce their continuing relevance as key members of a federal system of government. It proposes that skilful deployment of policy ideas and analyses can enable the states to sustain alternative national agendas despite hostility or lack of interest by the federal government. In conclusion, the article examines the implications for federal-state relations under the Rudd government. It suggests that the elements for productive reform agendas are present but that bringing them together will require considerable effort.  相似文献

  • Application of an issues management approach to corporate social responsibility consists of identifying, evaluating and responding to those issues that an industry must address in order to be socially responsible. This research focussed on identifying social and environmental issues relevant to the US forest products manufacturing industry. Towards this end, 14 interviews were conducted with key‐informants drawn from non‐government organizations, government and political offices, forest products associations, a multilateral organization and an extension expert. A rich set of issues was generated covering social and environmental issues. However, such a set may contain issues that are far too radical and may be challenging for companies to pursue. Accordingly, in order to develop a doable, socially credible and concise set of issues, a Delphi technique was employed consisting of forest products management and marketing academicians from various US universities. A two‐round Delphi resulted in identification of six social and six environmental issues that the US forest products manufacturing industry must address in order to be socially responsible. This proposed two‐stage process may have special relevance for companies that are entering into new markets overseas.
