A common criticism of merit‐pay plans is that they fail to systematically target rewards to the most effective teachers. This study presents new evidence on this issue by evaluating data from Tennessee's Career Ladder Evaluation System and the Project STAR class‐size experiment. Because the students and teachers participating in the experiment were randomly assigned, inferences about the relative quality of teachers certified by the career ladder should be unbiased. The results indicate that Tennessee's career ladder had mixed success in rewarding teachers who increased student achievement. Assignment to career‐ladder teachers increased mathematics scores by roughly 3 percentile points but generally had smaller and statistically insignificant effects on reading scores. © 2004 by the Association for Public Policy Analysis and Management.  相似文献

In studies of transitional systems, negative economic outcomes are often associated with 'partial' or 'stalled' reform – a reform that signifies an institutional departure from standard market operation. Such departures are often traced to socio-political contestation or political preferences. Focusing on China's intertwined financial and enterprise reforms, this paper challenges that approach on two fronts. First, it argues that institutional change and resultant economic outcomes are driven less by contestation than by societally held assumptions regarding the nature of economic causation in market contexts. The analytical lenses that actors employ to understand their environment shape expectations about how markets function, influence the manner by which economic problems are diagnosed, and profoundly affect the ultimate institutional evolution of the system. Second, such lenses are necessitated by substantial uncertainties at the theoretical level regarding market function – uncertainties that make characterizations of economic behavior as 'irrational' highly problematic.  相似文献

This research assessed whether there is an impact of race-ethnicity on depressed mood among adolescents, independent of socioeconomic status, whether gender differences in depressed mood are apparent within all race-ethnicity subgroups, and whether pubertal development influences depressed mood in a similar manner within gender and race-ethnicity subgroups. A three-stage, area probability sampling frame was utilized to select adolescents, ages 12–17 years, for an in-person interview. Depressed mood was assessed by the Children's Depression Inventory. Compared to Whites, African Americans, or Asian Americans, Latinos reported more symptoms of depressed mood, a finding that was independent of socioeconomic status. Advancing puberty was associated with depressed mood only among females, but the timing of pubertal changes, relative to ones peers, was related to depressed mood among both males and females, and among Latinos.  相似文献

Although it was a relatively quiet year for the courts and congressionalaction, 1997–1998 saw several developments that may significantlydefine federalism in the coming years. The 1998 federal budgetis projected to show a surplus, ending decades of deficit financinginWashington, D.C., but also raising questions about the budget'sfiscal impact on federalism and intergovernmental relations.Devolution took a back seat in Washington, D.C., as concernsabout managed care, education, and internet access led to proposalsfor increased federal involvement in state and local affairs.The states continued their implementation of welfare reformand launched other programs in health, environment.  相似文献

Drawing on data collected by Barry Latzer and using a logisticregression model that employs pooled time-series, this articletests a variety of factors for their impact on state high courtdecisions to diverge from U.S. Supreme Court criminal proceduredoctrines from 1969 to 1989. Several factors predict the developmentof independent state doctrines protective of civil liberties,including popular-vote retention elections and longer termsof office for state court justices, high court reputations,state wealth, and regional distinctions (with western courtsmost likely to advance individual rights). This study representsonly a small step in understanding an area of judicial behaviorthat has been long ignored in the political science literature.  相似文献

Abstract. The paper applies a structural perspective to the analysis of political preferences. Examining two British surveys, the 1987 cross–section of the electorate and a panel survey that covers the 1983 and 1987 elections, the research explores the bases of persistent voting for the same party, location on left–right scales, and the probability of holding the same policy views on a host of different issues over time. A set of structural variables rests at the heart of the paper's theory: discussion networks, patterns of interactions with members of political parties, social class networks, and location in the social structure. Several hypotheses guide the analysis: The effects of the structural variables on the probability of casting a ballot for the same political party in any one election and in adjacent elections will remain, even after controlling for party identification; political party socialization; location on left–right scales; positions taken on any and all political issues; age, and past levels of electoral stability. The effects of structural variables on left–right position will remain, even after controlling for locations on alternative left–right scales. Finally, reinforcing attitudinal context provides the only consistent determinant of stable policy positions, after controlling for a host of alternative explanations including level of education; age; interest in politics, and a general propensity to offer stable answers to political questions.  相似文献
