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

The most ferocious debates are about whether the United States should be described as imperial, but in practice other countries also try to influence other countries’ domestic policies, to propagate their visions, to exert power and to stabilize areas beyond their borders that are perceived as a source of threats. While in the 1990s the winners of globalization were seen as small open states, since the turn of the millennium big powers appear to be gaining because of their ability to project political power: the United States, but also China, Russia, India, and Brazil. This makes for a greater instability and leads to the formulation of theories of realism or neo-realism. The essay concludes with an examination of alternatives to empire and the neo-imperial vision, in particular the importance of elaboration of common or shared values in helping to build a safer and more peaceful international order. 相似文献

With new technically advanced methods and computers at our disposal, the efficient market hypothesis is once again being debated. At the same time, we are witnessing an unprecedented growth in both existing and new financial markets. These new markets are often in economies which have just recently embraced free market economics; we term these stock markets infant markets. Such stock markets are obviously not efficient in allocating the supply of savings to productive capital. We do not test whether or not these infant markets are informationally efficient, but instead examine whether and how they are becoming more efficient. We propose modelling the excess returns of individual securities using a multi-factor model with time-varying coefficients and generalised auto-regressive conditional heteroskedastic (GARCH) errors. If the markets are becoming more informationally efficient or the agents are learning, we would expect this to manifest itself as the time-varying coefficients becoming more stable as time increases. We test our model using data on four Bulgarian shares. First, we estimate an AR(2) model and a GARCH-M(1,1) model for the shares. Then, we estimated our AR(2) model with time varying coefficients and GARCH type errors. We find varying levels of efficiency and varying speeds of movement towards efficiency within our sample of four shares. 相似文献

This article argues that, despite environmental issues climbing higher on the political agenda and considerable recent policy activity, rhetoric is not matched by reality in our efforts to manage the Australian environment. We integrate the imperatives emerging from the policy and sustainability literatures and from actual policy, with detailed work on wildlife conservation in Victoria's Central Highlands. Our analysis demonstrates that, rather than undertaking the more intensive policy and 'adaptive management' that is needed, governments are often doing less and may actually be 'taking their hands of their wheel'. Some public policy and administration implications of the emerging policy field of sustainability are illustrated. 相似文献
