There is growing awareness and concern regarding the presence of chemical constituents of pharmaceuticals and personal care products (“PPCPs”) in the environment. A recent USGS study indicated that PPCPs are present at low levels in surface water throughout the U.S. Concern is based in part on the fact that certain PPCPs: (1) are designed to have biological effects (particularly pharmaceuticals), (2) are persistent in or continually added to the environment, (3) have negative environmental effects (specifically on aquatic life) even at low levels, and (4) potentially have cumulative and synergistic effects when combined with other PPCPs. The primary route of PPCPs into the environment is sewage discharges, septic systems, and large stock yards and feedlots where the unmetabolized PPCPs are excreted by humans and animals and end up in surface water and ground-water. Given these circumstances, manufacturers of PPCPs may face a risk of increased regulation and possibly litigation similar to that faced by oxygenate manufacturers and petroleum refiners over the use of Methyl Tertiary Butyl Ether (“MTBE”). Companies can take steps now and in the future that may minimize the impact of these risks.  相似文献

Recent studies point to the potential theoretical and practical benefits of focusing police resources on crime hot spots. However, many scholars have noted that such approaches risk displacing crime or disorder to other places where programs are not in place. Although much attention has been paid to the idea of displacement, methodological problems associated with measuring it have often been overlooked. We try to fill these gaps in measurement and understanding of displacement and the related phenomenon of diffusion of crime control benefits. Our main focus is on immediate spatial displacement or diffusion of crime to areas near the targeted sites of an intervention. Do focused crime prevention efforts at places simply result in a movement of offenders to areas nearby targeted sites—“do they simply move crime around the corner”? Or, conversely, will a crime prevention effort focusing on specific places lead to improvement in areas nearby—what has come to be termed a diffusion of crime control benefits? Our data are drawn from a controlled study of displacement and diffusion in Jersey City, New Jersey. Two sites with substantial street‐level crime and disorder were targeted and carefully monitored during an experimental period. Two neighboring areas were selected as “catchment areas” from which to assess immediate spatial displacement or diffusion. Intensive police interventions were applied to each target site but not to the catchment areas. More than 6,000 20‐minute social observations were conducted in the target and catchment areas. They were supplemented by interviews and ethnographic field observations. Our findings indicate that, at least for crime markets involving drugs and prostitution, crime does not simply move around the corner. Indeed, this study supports the position that the most likely outcome of such focused crime prevention efforts is a diffusion of crime control benefits to nearby areas.  相似文献

Know-Where: Geographies of Knowledge of World Politics   总被引:1,自引:1,他引:0  
The problem of "foundations" is a crucial one for any field, particularly perhaps one with as varied a possible repertoire of elementary sources as the study of world politics. In this paper, I draw attention to how some different ways of thinking about where knowledge is produced and how it circulates can be used to inform understanding about geographies of knowledge of world politics. Such geographies, however, are not ends in themselves. The point is to understand the ontological bases of knowing from perspectives that do not privilege a singular history of knowledge associated with a specific world region or of conceptions of knowledge that implicitly or explicitly presume their self-evident universality. In other words, we need to move beyond the all-too-conventional repertoires of relativism and positivism in understanding the bases to knowing about world politics/international relations. The paper suggests some ways forward, which should now be the subject of vigorous debate.  相似文献

This article analyses influences which in recent decades have changed the way in which public administration has been taught in British higher education. Focusing mainly on the former polytechnics, the article argues that a curriculum shift away from the social sciences and towards management, and changes in the nature of the British public sector, have profoundly influenced approaches to teaching public administration. It suggests that learning strategies are closely related to debate about the nature of the discipline and its location within the academic spectrum. The article also raises questions about the extent to which public administration teachers in British universities are equipped to present the more applied and skills-based teaching which has often been adopted in recent years, and the tensions which this might pose particularly in the‘new’universities with the increasing emphasis upon academic research.  相似文献
