COMPSTAT, the latest innovation in American policing, has been widely heralded as a management and technological system whose elements work together to transform police organizations radically. Skeptical observers suggest that COMPSTAT merely reinforces existing structures and practices. However, in trying to assess how much COMPSTAT has altered police organizations, research has failed to provide a broader theoretical basis for explaining how COMPSTAT operates and for understanding the implications of this reform. This article compares two different perspectives on organizations—technical/rational and institutional—to COMPSTAT's adoption and operation in three municipal police departments. Based on fieldwork, our analysis suggests that relative to technical considerations for changing each organization to improve its effectiveness, all three sites adopted COMPSTAT in response to strong institutional pressures to appear progressive and successful. Furthermore, institutional theory better explained the nature of the changes we observed under COMPSTAT than the technical/rational model. The greatest collective emphasis was on those COMPSTAT elements that were most likely to confer legitimacy, and on implementing them in ways that would minimize disruption to existing organizational routines. COMPSTAT was less successful when trying to provide a basis for rigorously assessing organizational performance, and when trying to change those structures and routines widely accepted as being "appropriate." We posit that it will take profound changes in the technical and institutional environments of American police agencies for police departments to restructure in the ways anticipated by a technically efficient COMPSTAT.  相似文献

What is required for sustaining an alliance between union and environmental activists? Applying grounded theory to a case study in the Costa Rican banana sector, this article reveals five historical phases. First, unions and environmentalists identify common opportunity structures for joint action. Second, a preexisting network becomes a resource for mobilization. Third, the new coalition engages in communicative action that leads to shared identity and cultural framing and a foundation for handling exogenous global forces. Market policy changes in the fourth phase stimulate a transnational activist network and framing linkages. Dramatic supply disruptions in the fifth precipitate autonomous organizational approaches that require reframing, identity extension, and flexibility. This study argues that the Costa Rican case can be generalized to other labor‐environmental coalitions if such alliances create simple, open structures that agilely adapt to external opportunity structures and expand frames that encourage collaborative autonomy and dualistic collective definitions.  相似文献

This article evaluates the effectiveness of OAS mechanisms for safeguarding democracy through multilateral diplomacy, what some scholars have dubbed the interamerican defense of democracy regime. Drawing on a range of international relations theories, this study derives competing hypotheses about member states' responses to democratic crises in the Americas. It then analyzes all instances in which a collective response—that is, an application of Resolution 1080 or the Inter-American Democratic Charter—was debated in the OAS between 1991 and 2002. Patterns of state behavior suggest that domestic politics, rather than the structural or systemic traits of the interamerican system, best explain foreign policy responses to crises of democracy in the region. The OAS record in confronting such crises is uneven.  相似文献

This article is the result of a master's thesis about children and their universal right to be included in a family environment. This is not only protected under international law, but also intuitive to human beings. HIV‐AIDS continues to threaten lives of children, particularly in sub‐Saharan Africa in the form of orphaning. Looking at a case study from Kenya, it is revealed that, while legal protection is yet to be fully realized in the state, strong cultural norms of value are alive. Currently, the extended family system is the greatest protection to children orphaned or at risk of being orphaned. However, this system was made invisible in the domestic laws of Kenya under the Children Act 2001. This neglect calls for questions not only regarding the protection cultural norms may offer, according to the best interests of children, but also as to the cultural environment being created with the new law.  相似文献
