This study revisited the Philadelphia Foot Patrol Experiment and explored the longitudinal deterrent effects of foot patrol in violent crime hot spots using Sherman's (1990) concepts of initial and residual deterrence decay as a theoretical framework. It also explored whether the displacement uncovered during the initial evaluation decayed after the experiment ended. Multilevel growth curve models revealed that beats staffed for 22 weeks had a decaying deterrent effect during the course of the experiment, whereas those staffed for 12 weeks did not. None of the beats had residual deterrence effects relative to the control areas. The displacement uncovered had decayed during the 3 months after the experiment, and it is theoretically plausible that previously displaced offenders returned to the original target areas causing inverse displacement. These results are discussed in the context of Durlauf and Nagin's (2011) recent proposal that prison sentences should be shortened, mandatory minimum statutes repealed, and the cost savings generated by these policy changes shifted into policing budgets to convey more effectively the certainty of detection. It is concluded that if Durlauf and Nagin's proposal is to succeed, then more holistic policing strategies would likely be necessary. Foot patrol as a specific policing tactic seems to fit nicely into a variety of policing paradigms, and suggestions for incorporating them to move beyond strictly enforcement‐based responses are presented.  相似文献

Abstract

This article looks at an earlier episode in the history of the UK border security apparatus by examining how the immigration control system was used in the 1970s and 1980s to detect potential terrorists from the Middle East and North Africa. Using recently opened archival records, it shows that the UK government introduced a strict system of visa checks, interviews, and other measures to nearly all Middle Eastern and North African visitors to the UK to prevent the entry of suspected terrorist personnel. By using these highly arbitrary measures, it became the modus operandi of the UK authorities to treat all Middle Eastern and North Africans as potential terrorists until convinced otherwise.  相似文献

Employee empowerment involves the delegation of decision-making to employees, while holding them accountable for outcomes. Survey data show that while sixty-two percent of state agencies in correction, transportation, health, education and welfare use empowerment in at least one service function, only six percent of agencies use empowerment throughout more than 75 percent of the agency. Empowerment is frequently implemented through coordination across units and through mid-level management teams. Training is also widely used. Agency directors report that employee empowerment has a positive impact on group decision-making ability, communication throughout units and commitment to stakeholders, as well as quality and productivity improvement.  相似文献

Through ethnography of Ashaninka communities' involvement in timber extraction in Peruvian Amazonia and an engagement with recent discussions around Buen Vivir the article interrogates the common association between indigenous notions of ‘living well’ and environmental protection. A key insight is that Ashaninka individuals emphasise everyday well-being and equality over the preservation of their surroundings. Older critiques of extractivism are used to show the recent advent of environmentalist discourses and highlight issues connected with emphasising ontological difference. The article concludes that Buen Vivir would be better framed as a desire, and right, to self-determination rather than being associated with specific behaviours.  相似文献

Cross-national research on taxation is a growth industry in political science. This article discusses key conceptual and measurement issues raised by such studies. First, it highlights the ways in which taxation has been studied as a rich and varied concept, including as a component of the state-building process, as a collective action problem, and/or as a problem of distributive justice. Second, the article identifies the central tradeoffs associated with the construction of taxation indicators used to measure such ideas. It discusses considerations such as which forms of revenue should be included and which should not, whether and how to standardize taxation measures, and how no fine-tune measures through a clear specification of units, universes, and measurement calibration. These choices have important implications for the “scoring” of countries, and for making valid inferences about the relationship between states and societies. Evan S. Lieberman is a Robert Wood Johnson Scholar at Yale University and will begin and appointment as assistant professor in the Department of Politics at Princeton University in September 2002. His interests include comparative politics, research methods, and economic and social policy. I would like to thank Christopher Achen, David Collier, Marc Morjé Howard, Lucan Way, members of the Robert Wood Johnson Policy Scholars Seminar at Yale University, three anonymous reviewers, and the editors atStudies in Comparative International Development for their valuable comments and suggestions.  相似文献
