Objectives
This study examines the effectiveness of foot patrol in violent micro-places. A large urban police department deployed foot patrol in micro-places (hot spots) for a period of 90 days for two shifts each day. Our objective is to determine whether this activity impacted violent crime in these hot spots and whether spatial displacement of crime occurred.Methods
Eight eligible foot beat locations were set by examining crime rates for previous years in order to identify micro-places of high criminal activity. We employed a quasi-experimental design comparing the four treatment to the four control areas, estimating panel-specific autoregressive models for 30 weeks prior to and 40 weeks after the treatment.Results
Time series models revealed statistically significant reductions in violent crime in the micro-places receiving foot patrol treatment, while no such reductions were observed in the control areas. The deterrent effect, however, was short and dissipated quickly. Control areas did not experience any crime prevention benefit during this time period. No evidence of crime displacement to spatially contiguous areas was detected.Conclusions
This contributes to the growing body of knowledge that focused police strategies within hot spots impact violent crime. Specifically, the implementation of foot patrol in high crime hot spots led to measurable reductions in aggravated assaults and robberies, without displacing crime to contiguous areas.164.
This paper attempts to test the power of the median model againstthe respective strength of other alternate models based onredistributive, political-institutional and interest group theoriesin explaining the demand for public spending in New York statecounties during 1990, 1980 and 1970. To execute the comparison ofthe performance of median voter model with that of each of thenonmedian voter ones, various nonnested tests such as J and JAtests, N-tilde, W and encompassing tests have been employed.Results of the study show that although the median voter model hasa marginal edge over the rival models based on the alternativetheories, it may not be relied upon solely when many otherinstitutional, redistributive and interest group factors are alsorelevant for explaining public spending. The results of this studydiffer from those in Congleton and Bennett (1995). We do not findthat interest group models are substantially weaker than the medianvoter model. 相似文献

Abstract. Duverger's propositions concerning the psychological and mechanical consequences of electoral rules have previously been examined mainly through the lens of district magnitude, comparing the properties of single–member district plurality elections with those of multimember proportional representation elections. The empirical consequences of multimember plurality (MMP) rules, on the other hand, have received scant attention. Theory suggests that the effect of district magnitude on the number and concentration of parties will differ with regard to whether the allocation rules are plurality–based or proportional. I test this theory by drawing on a uniquely large–sample dataset where district magnitude and electoral formula vary but the basic universe of political parties is held constant, applying regression analysis to data from several thousand Hungarian local bodies elected in 1994 consisting of municipal councils, county councils, and mayors. The results indicate that omitting the variable of electoral formula has the potential to cause significant bias in estimates of Duvergerian consequences of district magnitude. In addition, the analysis of multi–member plurality elections from the local election dataset reveals counter–intuitively that candidate and party entry may increase with district magnitude under MMP, suggesting important directions for future investigation of MMP rules. 相似文献

This paper explores Senate policy-making toward Israel from 1993–2002. Previous scholarship suggests that congressional policymaking toward Israel is heavily influenced by the ethnic and religious identification of both legislators and their constituents, not simply by legislators' abstract perceptions of the national interest. Other literature de-emphasizes the likelihood that constituent interests will affect Congressional foreign policy making. We test for an impact of both elite and constituent characteristics on Congressional support for Israel, using sponsorship–cosponsorship decisions in the 103rd–107th Congresses. Israel's strongest supporters in this period are shown to be Jewish, conservative, Republican, and evangelical senators. Notably, elite characteristics (partisanship, ideology, and religion) matter more than constituency factors, with the exception of the Jewish population in senators' home states. While Jewish and conservative senators have long been vocal supporters of Israel, evangelical and Republican senators have not historically taken such a strong pro-Israel stance; hence they are relatively new additions to the active pro-Israel coalition. Thus the pro-Israel coalition shows both continuity and change as it has broadened to include new partners. However, we suggest that this coalition is not necessarily stable and may undergo further evolution in the future. 相似文献
