Analyzing The Influence Of Micro-Level Factors On Cctv Camera Effect., Eric L. Piza, Joel M. Caplan, Leslie W. Kennedy

Publications and Research

Objectives Despite the popularity of closed circuit television (CCTV), evidence of its crime prevention capabilities is inconclusive. Research has largely reported CCTV effect as ‘‘mixed’’ without explaining this variance. The current study contributes to the literature by testing the influence of several micro-level factors on changes in crime levels within CCTV areas of Newark, NJ.

Methods Viewsheds, denoting the line-of-sight of CCTV cameras, were units of analysis (N = 117). Location quotients, controlling for viewshed size and control-area crime incidence, measured changes in the levels of six crime categories, from the pre-installation period to the post-installation period. Ordinary least squares …

A Plague On Both Your Houses? Risks, Repeats, And Reconsiderations Of Urban Residential Burglary, William D. Moreto, Eric L. Piza, Joel M. Caplan

Publications and Research

Research has shown that mapping techniques are useful in forecasting future crime events. However, the majority of prospective mapping techniques has focused on the event-dependent influence of instigator incidents on subsequent incidents and does not explicitly incorporate the risk heterogeneity of the setting. The study here discussed is a modest attempt to address this issue by using a two-step process: first, using risk terrain modeling, we operationalized the “environmental backcloth,” (the risk heterogeneity of an area) to forecast locations of residential burglaries in the urban city of Newark, New Jersey. Second, using the near repeat calculator, we assessed the variability …

Spatial Risk Factors Of Felonious Battery To Police Officers, Joel M. Caplan, Philip L. Marotta, Eric L. Piza, Leslie W. Kennedy

Publications and Research

Purpose – The purpose of this paper is to examine the spatial influence of features of the physical environment on the risk of aggression toward law enforcement.

Design/methodology/approach – The spatial analytic technique, risk terrain modeling was performed on felonious battery data provided by the Chicago Police Department.

Findings – Out of the 991 batteries against law enforcement officers (LEOs) in Chicago, 11 features of the physical environment were identified as presenting a statistically significant spatial risk of battery to LEOs. Calls for service within three blocks of foreclosures and/or within a dense area of problem buildings pose as much …

The Growth Of Incarceration In The United States: Exploring Causes And Consequences, Jeremy Travis, Bruce Western, F. Stevens Redburn

Publications and Research

After decades of stability from the 1920s to the early 1970s, the rate of incarceration in the United States more than quadrupled in the past four decades. The Committee on the Causes and Consequences of High Rates of Incarceration in the United States was established under the auspices of the National Research Council, supported by the National Institute of Justice and the John D. and Catherine T. MacArthur Foundation, to review evidence on the causes and consequences of these high incarceration rates and the implications of this evidence for public policy.

Our work encompassed research on, and analyses of, the …

Saturation Foot-Patrol In A High-Violence Area: A Quasi-Experimental Evaluation, Eric L. Piza, Brian A. O'Hara

Publications and Research

This study incorporates a quasi-experimental design to evaluate a saturation foot-patrol initiative in Newark, NJ. Violent crime was measured for one year prior and during the initiative within the target area, a surrounding catchment area, and two separate control areas. The overall findings provide further sup- port for foot-patrol as a crime prevention tactic. Total street violence as well as the disaggregate categories of murder, shootings, and nondomestic aggravated assault decreased within the target area absent of any displacement effects. However, robbery suffered from substantial levels of both temporal and spatial displacement, showing saturation foot-patrol to have varying impact on …
