Measuring The Effect Heterogeneity Of Police Enforcement Actions Across Spatial Contexts, Eric L. Piza

Publications and Research

Purpose: This study tests whether the effect of police actions is influenced by similar crime generators and attractors (CGAs) that influence crime. Said differently, in recognition that the presence of CGAs presents higher risk of crime at certain places, we test whether CGAs similarly create a situation where specific police enforcement actions are more effective at certain types of places than others.

Methods: Using longitudinal logistic regression models incorporating panel data, we measure the effect of various police enforcement actions on gun violence in Newark, NJ. Risk Terrain Modeling (RTM) was further used to test whether the effect of the …

Script Analysis Of Open-Air Drug Selling: A Systematic Social Observation Of Cctv Footage, Victoria A. Sytsma, Eric L. Piza

Publications and Research

Objectives: Through the use of closed-circuit television (CCTV) video foo- tage, the current study builds upon the drug transaction work of Piza and Sytsma by developing a crime script for open-air drug selling.

Methods: Researchers conducted a systematic social observation of CCTV footage of open-air drug markets in Newark, NJ. The data were used to identify sequential stages of drug transactions. Fisher’s exact tests measured whether buyer and seller activities during specific acts of the drug transaction event were related to activities seen in subsequent stages.

Results: This study finds three distinct acts to open-air drug events. During the pretransaction …

The Crime Prevention Effect Of Cctv In Public Places: A Propensity Score Analysis, Eric L. Piza

Publications and Research

This study measures the effect of CCTV in Newark, NJ across three separate crime categories: auto theft, theft from auto, and violent crime. CCTV viewsheds, denoting camera line-of-sight, were units of analysis. Viewsheds for treatment units were created by digitizing live CCTV footage within a geographic information system (GIS). Control viewsheds were created with GIS tools and aerial imagery from Google maps. Treatment cases were matched with control cases via propensity score matching (PSM) to ensure statistical equivalency between groups. Effect was measured via odds ratios and average treatment on the treated statistics. Findings offer modest support for CCTV as …

The Effect Of Various Police Enforcement Actions On Violent Crime: Evidence From A Saturation Foot-Patrol Intervention, Eric L. Piza

Publications and Research

The current study tests the crime prevention effect of different police actions conducted during a foot-patrol saturation initiative in Newark, New Jersey. Police actions were categorized into two typologies: enforcement actions (i.e., arrests, quality of life summonses and field interrogations) and guardian actions (i.e., business checks, citizen contacts, bus checks, and taxi inspections). Logistic regression models tested the effect of enforcement and guardian actions on crime during daily (i.e., 24-hr) periods as well as the intervention’s operational (6:00 p.m.-2:00 a.m.) and nonoperational (2:00 a.m.-5:00 p.m.) periods. Analyses were conducted twice, once for the Operation Impact target area and once for …

Facilitators And Impediments To Designing, Implementing, And Evaluating Risk-Based Policing Strategies Using Risk Terrain Modeling: Insights From A Multi-City Evaluation In The United States, Eric L. Piza, Les W. Kennedy, Joel M. Caplan

Publications and Research

The contemporary policing literature contains numerous examples of partnerships between academic researchers and police agencies. Such efforts have greatly contributed to evidence-based policing by increasing the knowledge base on effective strategies. However, research has demonstrated that successful collaboration between researchers and practitioners can be a challenge, with various organizational and inter-agency factors presenting difficulties at various stages of the process. Additionally, applied research can oftentimes face implementation challenges when the time comes to convert research into practice. The current study contributes to the literature by discussing researcher/practitioner partnerships and program implementation in the context of a multi-city risk-based policing project …

The Punishment Marketplace: Competing For Capitalized Power In Locally Controlled Immigration Enforcement, Daniel L. Stageman

Publications and Research

Neoliberal economics play a significant role in US social organization, imposing market logics on public services and driving the cultural valorization of free market ideology. The neoliberal ‘project of inequality’ is upheld by an authoritarian system of punishment built around the social control of the underclass—among them unauthorized immigrants. This work lays out the theory of the punishment marketplace: a conceptualization of how US systems of punishment both enable the neoliberal project of inequality, and are themselves subject to market colonization. The theory describes the rescaling of federal authority to local centers of political power. Criminal justice policy activism by …

Cognitive Sociology, Michael W. Raphael

Publications and Research

Cognitive sociology is the study of the conditions under which meaning is constituted through processes of reification. Cognitive sociology traces its origins to writings in the sociology of knowledge, sociology of culture, cognitive and cultural anthropology, and more recently, work done in cultural sociology and cognitive science. Its central questions revolve around locating these processes of reification since the locus of cognition is highly contentious. Researchers consider how individuality is related to notions of society (structures, institutions, systems, etc.) and notions of culture (cultural forms, cultural structures, sub-cultures, etc.). These questions further explore how these answers depend on learning processes …

Cctv As A Tool For Early Police Intervention: Preliminary Lessons From Nine Case Studies., Eric Piza, Joel M. Caplan, Leslie W. Kennedy

Publications and Research

This study explores the prospect of utilizing CCTV as an early intervention mechanism to detect and disrupt street-level activity that can lead to violence. The analysis focuses on nine case studies in Newark, NJ, incorporating data from several sources, including video footage, computer-aided dispatch (CAD) system incident data, CAD event chronologies and face-to-face interviews with CCTV operators. The findings suggest that the benefits offered by CCTV, namely the instantaneous discovery and reporting of crime, may be rendered incon- sequential by the process times associated with the differential-response policy of police dispatch. Potential methods by which police can more proactively utilize …

Crime In Context: Utilizing Risk Terrain Modeling And Conjunctive Analysis Of Case Configurations To Explore The Dynamics Of Criminogenic Behavior Settings., Joel M. Caplan, Leslie W. Kennedy, Jeremy D. Barnum, Eric L. Piza

Publications and Research

Risk terrain modeling (RTM) is a geospatial crime analysis tool designed to diagnose environmental risk factors for crime and identify the places where their spatial influence is collocated to produce vulnerability for illegal behavior. However, the collocation of certain risk factors’ spatial influences may result in more crimes than the collocation of a different set of risk factors’ spatial influences. Absent from existing RTM outputs and methods is a straightforward method to compare these relative interactions and their effects on crime. However, as a multivariate method for the analysis of discrete categorical data, conjunctive analysis of case configurations (CACC) can …

The Crime Kaleidoscope: A Cross-Jurisdictional Analysis Of Place Features And Crime In Three Urban Environments, Jeremy D. Barnum, Joel M. Caplan, Leslie W. Kennedy, Eric L. Piza

Publications and Research

Research identifies various place features (e.g., bars, schools, public transportation stops) that generate or attract crime. What is less clear is how the spatial influence of these place features compares across relatively similar environments, even for the same crime. In this study, risk terrain modeling (RTM), a geospatial crime forecasting and diagnostic tool, is utilized to identify place features that increase the risk of robbery and their particular spatial influence in Chicago, Illinois; Newark, New Jersey; and Kansas City, Missouri. The results show that the risk factors for robbery are similar between environments, but not necessarily identical. Further, some factors …

The Current And Potential Role Of Crime Analysts In Evaluations Of Police Interventions: Results From A Survey Of The International Association Of Crime Analysts, Eric Piza, Shun Q. Feng

Publications and Research

Crime analysts play a pivotal role in evidence-based policing by readily diagnosing the nature of crime and disorder problems. Such analysis products are key in the design of evidence-based strategies. The role of analysts in the subsequent process of evidence-based policing, the evaluation of programs to determine what works, is less known. The current study seeks to fill this gap in the literature through a survey of the International Association of Crime Analyst Membership. Findings suggest that program evaluation lies on the periphery of the crime analysis profession. Across all measures incorporated in this study, program evaluation was emphasized less …

The Influence Of Community Areas, Neighborhood Clusters, And Street Segments On The Spatial Variability Of Violent Crime In Chicago, Cory Schnell, Anthony A. Braga, Eric L. Piza

Publications and Research

Objectives: The influence of three hierarchical units of analysis on the total spatial variability of violent crime incidents in Chicago is assessed. This analysis seeks to replicate a recent study that found street segments, rather than neighborhood units of analysis, accounted for the largest share of the total spatial variability of crime in The Hague, Netherlands (see Steenbeek and Weisburd J Quant Criminol. doi:10.1007/s10940-015- 9276-3, 2015).

Methods: We analyze violent crime incidents reported to the police between 2001 and 2014. 359,786 incidents were geocoded to 41,926 street segments nested within 342 neighborhood clusters, in turn nested within 76 community areas …

The Influence Of Job Assignment On Community Engagement: Bicycle Patrol And Community-Oriented Policing, Victoria A. Sytsma, Eric L. Piza

Publications and Research

The purpose of this study is to compare a specialized community-oriented policing (COP) unit to a reactive unit on officer perceptions of public contact and officer perceptions of job performance. We also compare bicycle patrol officers to motor vehicle patrol officers within these units. Using a static group comparison design, questionnaires were distributed to officers within the Toronto Police Service (n = 178). Bicycle patrol is associated with more contacts with the public and higher rates of proactive policing when compared to motor vehicle patrol and bicycle officers are more likely to rate higher on several measures of crime control. …

Spatiotemporal Convergence Of Crime And Vehicle Crash Hotspots: Additional Consideration For Policing Places, Jeremy G. Carter, Eric L. Piza

Publications and Research

Policing strategies that seek to simultaneously combat crime and vehicle crashes operate under the assumption that these two problems have a corollary relationship—an assumption that has received scant empirical attention and is the focus of the present study. Geocoded vehicle crash, violent crime, and property crime totals across were aggregated to Indianapolis census blocks over a 36-month period (2011-2013). Time series negative binomial regression and local indicators of spatial autocorrelation analyses were conducted. Results indicate that both violent and property crime are significantly related to vehicle crash counts, both overall and during the temporal confines of patrol tours. Relationship strength …

Predicting Initiator And Near Repeat Events In Spatiotemporal Crime Patterns: An Analysis Of Residential Burglary And Motor Vehicle Theft, Eric L. Piza, Jeremy G. Carter

Publications and Research

Near repeat analysis has been increasingly used to measure the spatiotemporal clustering of crime in contemporary criminology. Despite its predictive capacity, the typically short time frame of near repeat crime patterns can negatively affect the crime prevention utility of near repeat analysis. Thus, recent research has argued for a greater understanding of the types of places that are most likely to generate near repeat crime patterns. The current study contributes to the literature through a spatiotemporal analysis of residential burglary and motor vehicle theft in Indianapolis, IN. Near Repeat analyses were followed by multinomial logistic regression models to identify covariates …

Publications and Research

Objectives: This study presents a cost–benefit analysis of an intervention pairing proactive CCTV monitoring with directed police patrol in Newark, NJ. A recent randomized control trial found that the strategy generated significant crime reductions in treatment areas relative to control areas. The current study focuses on the financial implications of the experimental strategy through a cost–benefit analysis.

Methods: The study begins by measuring the costs and benefits associated with the experimental strategy, the findings of which can inform agencies with existing CCTV infrastructure. Follow-up analyses measure the costs and benefits of the intervention for agencies absent existing CCTV infrastructure, meaning …

Vulnerability And Exposure To Crime: Applying Risk Terrain Modeling To The Study Of Assault In Chicago., Leslie W. Kennedy, Joel M. Caplan, Eric L. Piza, Henri Buccine-Schraeder

Publications and Research

Prior research has applied risk assessment and spatial analysis techniques to the study of violence. This paper builds on those results, tying the practical outcomes of spatial risk analysis methods to broader spatial issues on the articulation of risky places for aggravated assault. We begin by conceptualizing key relationships, addressing the effects of environmental factors on creating distinct, identifiable areas that are conducive to crime. Propositions of the theory of risky places are posed and then empirically tested using a GIS based program, RTMDx, on aggravated assault data in an urban area. Given the current thinking about crime vulnerability based …

Exploring The Defensive Actions Of Drug Sellers In Open-Air Markets: A Systematic Social Observation., Eric Piza, Victoria A. Sytsma

Objectives: The current study contributes to the literature through a systematic social observation of the defensive actions of drug sellers within open-air retail markets. The study expands upon previous literature by incorporating a novel data collection and coding method.

Methods: Video footage of narcotics transactions was extracted from the closed-circuit television (CCTV) system of the Newark, NJ Police Department. Researchers transcribed and coded the footage to measure the frequency of defensive actions incorporated by drug sellers. Fisher’s exact tests measured whether the frequency of each defensive action significantly differed across geographic setting or time of day.

Results: The frequency of …

Place-Based Correlates Of Motor Vehicle Theft And Recovery: Measuring Spatial Influence Across Neighbourhood Context, Eric L. Piza, Shun Feng, Leslie Kennedy, Joel Caplan

Publications and Research

Social scientists have long shown great interest in the spatial correlates of crime patterns. A subset of the literature has focused on how micro-level spatial factors influence the formation of crime hot spots. At the same time, tangential research has highlighted how neighbourhood disadvantage influences crime occurrence. The current study focuses on the intersection of these perspectives through a spatial analysis of Motor Vehicle Theft (MVT) and Motor Vehicle Recovery (MVR) in Colorado Springs, CO. We begin by conducting a Risk Terrain Modelling analysis to identify spatial risk factors significantly related to MVT and MVR occurrence. We then test whether …

Publications and Research

Executive Summary: Taking place over 5 hours during the afternoon of November 10th, 2014, in John Jay College’s Gerald W. Lynch Theater, the American Justice Summit was an unprecedented public meeting of some of the most important individuals working in contemporary criminal justice reform. The event placed these individuals in front of an audience of six hundred-odd practitioners, activists, students, elected officials, and policy professionals, in conversation with leading journalists and each other, to describe the scope and contours of the problems posed by the country’s dysfunctional and interlocking systems of criminal justice – mass incarceration, police-community relations, the system’s …

The Effects Of Merging Proactive Cctv Monitoring With Directed Police Patrol: A Randomized Controlled Trial., Eric L. Piza, Joel M. Caplan, Leslie W. Kennedy, Andrew M. Gilchrist

Publications and Research

Objectives: This study was designed to test the effect of increased certainty of punishment on reported crime levels in CCTV target areas of Newark, NJ. The experimental strategy was designed for the purpose of overcoming specific surveillance barriers that minimize the effectiveness of CCTV, namely high camera-to-operator ratios and the differential response policy of police dispatch. An additional camera operator was deployed to monitor specific CCTV cameras, with two patrol cars dedicated to exclusively responding to incidents of concern detected on the experimental cameras.

Methods: A randomized controlled trial was implemented in the analysis. A randomized block design was used …

Risk Terrain Modeling For Spatial Risk Assessment., Joel M. Caplan, Leslie W. Kennedy, Jeremy D. Barnum, Eric L. Piza

Publications and Research

Spatial factors can influence the seriousness and longevity of crime problems. Risk terrain modeling (RTM) identifies the spatial risks that come from features of a landscape and models how they colocate to create unique behavior settings for crime. The RTM process begins by testing a variety of factors thought to be geographically related to crime incidents. Valid factors are selected and then weighted to produce a final model that basically paints a picture of places where crime is statistically most likely to occur. This article addresses crime as the outcome event, but RTM can be applied to a variety of …

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 …

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 …

Stage As Street: Representation At The Juncture Of The Arts And Justice, E. Gabriel Dattatreyan, Daniel L. Stageman

Publications and Research

Arts educators working with court-involved youth face a set of complex and imbricated challenges. First, how do we gain the interest of the young people we would have participate in what we imagine are col-laborative and mutually generative projects? Second, how do we mediate representational tensions when the project is not solely therapeutic but has a broader public pedagogical purpose—to disrupt the simplistic and pathologizing discourses of poverty and violence that so often capture young men and women of color in the United States? (Bourgois, 2002; Noguera, 2008). Third, and not least, how do we navigate the institutional settings where …

Joint Utility Of Event- Dependent And Environmental Crime Analysis Techniques For Violent Crime Forecasting, Joel M. Caplan, Leslie W. Kennedy, Eric L. Piza

Publications and Research

Violent crime incidents occurring in Irvington, New Jersey, in 2007 and 2008 are used to assess the joint analytical capabilities of point pattern analysis, hotspot mapping, near-repeat analysis, and risk terrain modeling. One approach to crime analysis suggests that the best way to predict future crime occurrence is to use past behavior, such as actual incidents or collections of incidents, as indicators of future behavior. An alternative approach is to consider the environment in which crimes occur and identify features of the landscape that would be conducive to crime. Thanks to advances in geographic information system technology and federally funded …
