In this paper, we consider several features of teacher‐retention policies based on value‐added measures of effectiveness under a variety of empirically grounded rules and parameters. We consider the effects of policy design by varying the standard above which satisfactory teachers are expected to perform. We simulate recently adopted policies that remove teachers based on consecutive unsatisfactory performance and compare these to policies that remove teachers based on poor performance on average over a multiyear period. We also consider the precision of the performance measure and the underlying variation in teacher quality on policy effects. Finally, the simulation makes a step forward by incorporating recent empirical findings of a relationship between teacher quality and natural attrition from the profession. Our results indicate that deselection policies based on value‐added measures have the potential to improve teacher quality, although understanding the role of policy design, self‐selected exits, and the underlying variation in teacher quality is essential for determining policy effects.  相似文献

ABSTRACT

This article provides a critical reading of the idea of ‘the reasonable’ in contemporary politics, as reflected in the work of John Rawls. I argue that this concept is best understood as a practice of political identification, which provides the template for mutual accommodation without concurrent agreement on any substantive commitments. However, by constructing a teleological story in which the reasonable leads naturally back to the liberal principles of justice, Rawls reveals the limits of the concept. Rather than ending political disagreement by establishing a shared foundation, prioritizing reasonableness only repurposes conflicts by transforming disagreement into a series of debates over the meaning of reasonableness itself, battles which are every bit as partisan and vicious as those Rawls sought to exclude. Revitalizing the idea of the reasonable requires abandoning the effort to deploy it as a technique of exclusion. Instead, reasonable politics should be oriented toward engagement with unreasonable critics.  相似文献

Abstract: J.E. (Ted) Hodgetts was influenced by both the political economy approach that he learned at the University of Toronto and by the comprehensive historical method developed by Leonard White, under whom he studied at Chicago. His first great project, Pioneer Public Service, convinced him that responsible government was impossible without responsible public administration. The authors examine how his response to management theories and practices evolved following his participation in the Glassco, Lambert and Gomery commissions. Hodgetts consistently refused the complete separation of politics and administration, and he promoted the use of management techniques to strengthen parliamentary supervision of the public service. The two key components of his legacy are thus a commitment to the democratic values of representative government and the comprehensive study of the internal dynamics of public administration in interaction with the relevant environmental factors.  相似文献

Trade coverage ratios are calculated to assess the 1991 incidence of non‐tariff measures (NTMs) on imports of products eligible for duty‐free treatment under the United States’ Caribbean Basin Economic Recovery Act (CBERA). Overall, 16 per cent of all CBERA‐eligible products were found to be covered by one or more NTM. Corresponding figures for all eligible products exported from individual beneficiaries range up to 40 per cent. Much higher trade coverage ratios are found for individual product groups. NTMs constitute important deterrents to US imports of CBERA‐eligible products. Heavy reliance on NTMs counters the intent of the CBERA, namely to extend preferential treatment to exports from Caribbean Basin countries.  相似文献
