Policies are implemented in complex networks of organizations and target populations. Effective action often requires managers to deal with an array of actors to procure resources, build support, coproduce results, and overcome obstacles to implementation. Few large-n studies have examined the crucial role that networks and network management can play in the execution of public policy. This study begins to fill this gap by analyzing performance over a five-year period in more than 500 U.S. school districts using a nonlinear, interactive, contingent model of management previously developed by the authors. The core idea is that management matters in policy implementation, but its impact is often nonlinear. One way that public managers can make a difference is by leveraging resources and buffering constraints in the program context. This investigation finds empirical support for key elements of the network-management portion of the model. Implications for public management are sketched.  相似文献

Most literature on public-sector networks focuses on how to build and manage systems and ignores the political problems that networks can create for organizations. This article argues that individual network nodes can work to bias the organization's actions in ways that benefit the organization's more advantaged clientele. The argument is supported by an analysis of performance data from 500 organizations over a five-year period. A classic theoretical point is supported in a systematic empirical investigation. While networks can greatly benefit the organization, they have a dark side that managers and scholars need to consider more seriously.  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

Scattered case studies of recall procedures can be found in the literature on particular countries, and recent literature has drawn attention to the growth and diffusion of this family of practices. But the long genealogy, and the wide international distribution, of the recall process has been overlooked in the broader study of democratization, institutional design, and political representation. This article presents the two original country studies and situates them within the emerging field of comparative research. Four major themes are highlighted: the multiple and often subterranean sources of these experiments; their fluctuating profiles and (mostly) low external visibility; the relative weight of diffusion versus independent invention; and the resulting design pitfalls, as well as the potential benefits when carefully introduced.  相似文献
