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

Despite some understanding of general correlates and possible antecedents to intimate partner violence (IPV) within the Christian community, the impact of religious and spiritual factors tends to be confounded by other factors and is often misjudged. Archival data from Wave III of the National Longitudinal Study of Adolescent Health (Add Health) were used to examine the impact of nine religious and spiritual factors on the probability of IPV perpetration by males, aged 18 to 26, who nominally classified themselves as Catholic, Protestant, or Christian. Logistic regression results indicated that IPV perpetration could not be adequately predicted from the religious and spiritual factors. Given the geographic breadth and the size of the Add Health sample, no finding of a predictive model for Christian male-perpetrated IPV challenges the paradigm that religious and spiritual factors should be overtly addressed in faith-based batterers’ programs targeting young adult males.  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

He was only a little monkey, a very little one the first timeI saw him, not more than 9 inches tall; and when he died 3 yearslater, fully grown, he did not measure more than a foot anda half.  相似文献
