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

  • Public appointments for committees or boards can be controversial due to cronyism or pandering to demands of noisy or powerful interest groups. One relatively unexplored method for selecting committee or board members is random selection which has advantages beyond interrupting cronyism. This paper canvasses the strengths and weaknesses of an unusual selection method and makes a case for the use of a lottery as a robust process that will lend legitimacy and credibility to committee or board governance.

  • 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.

The article argues that Islamist terror is driven by irrational forces; it analyzes jihadist values and doctrines that animate Islamic revolutionaries; it then contends that jihadist movements go through a cycle of mobilization, extremism, implosion and recreation. Finally, it assesses the prospects for jihadist revitalization, extremism, and decline in Syria and the Sahel. Examples from the Iraqi and Algerian jihadist campaigns are used for illustrative purposes throughout.  相似文献
