Dynamic Risk Trajectories, Community Context, And Juvenile Recidivism, Kevin T. Wolff, Michael T. Baglivio, Jonathan Intravia May 2023

Dynamic Risk Trajectories, Community Context, And Juvenile Recidivism, Kevin T. Wolff, Michael T. Baglivio, Jonathan Intravia

Publications and Research

Purpose

While the implementation of risk assessment has expanded, the extent to which there are different trajectories of risk/protective factors among adjudicated youth during supervision in the community remains unanswered. The goal of the current study is to identify the distinct trajectories in dynamic risk and protective factors among youth on probation and assess whether different patterns in risk over time are associated with continued offending.

Method

Group-based trajectory modeling is used to identify distinct trajectories across multiple domains of risk/need. The individual- and neighborhood-level factors associated with these trajectories are then explored, prior to examining their relationship to continued …


Neighbors At Risk, Jeffrey A. Butts, Gina Moreno, Richard A. Espinobarros Apr 2022

Neighbors At Risk, Jeffrey A. Butts, Gina Moreno, Richard A. Espinobarros

Publications and Research

Most New York City neighborhoods did not experience high rates of shootings in recent years, but others clearly did. Comparing crime rates across these relatively small geographic areas is important for officials considering where to invest in resources that support public safety and community wellbeing.


The Effect Of The Seattle Police-Free Chop Zone On Crime: A Microsynthetic Control Evaluation, Eric L. Piza, Nathan T. Connealy Jan 2022

The Effect Of The Seattle Police-Free Chop Zone On Crime: A Microsynthetic Control Evaluation, Eric L. Piza, Nathan T. Connealy

Publications and Research

Research Summary:

Nightly confrontations occurred between protestors and officers outside of the Seattle Police Department’s (SPD’s) East precinct in the aftermath of George Floyd’s murder. On June 8, 2020, the SPD abandoned the East precinct in an attempt to calm the situation. Following closure of the precinct, the Capitol Hill Occupation Protest (CHOP) took hold in the surrounding 6-block area. The CHOP occupation lasted until July 1, 2020. Over this time period, CHOP operated as an autonomous zone, with police officers not patrolling and generally not responding to calls for police service within the area. We used the microsynthetic control …


Adverse Childhood Experiences Distinguish Violent Juvenile Sexual Offenders’ Victim Typologies, Michael T. Baglivio, Kevin T. Wolff Oct 2021

Adverse Childhood Experiences Distinguish Violent Juvenile Sexual Offenders’ Victim Typologies, Michael T. Baglivio, Kevin T. Wolff

Publications and Research

Juvenile perpetrators account for over 25% of all sexual offenses, and over one-third of such offenses are against victims under the age of 18. Given empirical connections between adverse childhood experience (ACE) exposure and perpetration of violence, we create victim typologies based on the juveniles’ relationship to their victims among 5539 justice-involved adolescents who have committed violent against-person sexual felonies. Multinomial logistic regression is used to assess which covariates, including individual ACE exposures and cumulative traumatic exposures, are associated with victim typologies. This approach allows for better targeting of violence prevention efforts, as a more nuanced understanding of the increased …


Shooting Trends Vary Across Areas Of New York City, Jeffrey A. Butts, Richard A. Espinobarros Oct 2021

Shooting Trends Vary Across Areas Of New York City, Jeffrey A. Butts, Richard A. Espinobarros

Publications and Research

Recent reports point to slight reductions in New York City’s recent surge of shooting incidents. The number of shooting incidents was higher in 2020 and 2021 than in 2019, but the rate of increase appeared to be slowing. The degree of change varied across areas of the city.


Hostile, Quick-Tempered, And Exposed To Dangerous Environments: Exploring The Link Between Temperament And Street Code Adherence, Kevin T. Wolff, Sharron Spriggs, Jonathan Intravia, Michael T. Baglivio, Matt Delisi Sep 2021

Hostile, Quick-Tempered, And Exposed To Dangerous Environments: Exploring The Link Between Temperament And Street Code Adherence, Kevin T. Wolff, Sharron Spriggs, Jonathan Intravia, Michael T. Baglivio, Matt Delisi

Publications and Research

Although Elijah Anderson’s (1999) code of the street thesis has received a great deal of scholarly attention, fewer studies have examined the characteristics associated with its adoption. Existing evidence is supportive of Anderson’s initial observations, however, less is known about the association between personality and emotional characteristics and adopting street code norms. The current study assesses the role of Delisi and Vaughn’s difficult temperament index in the adoption of the street code among a sample of juvenile justice-involved youth. Results indicated youth with more difficult temperaments, characterized by lower levels of effortful control and higher levels of negative emotionality, were …


Police Officers’ Best Friend?: An Exploratory Analysis Of The Effect Of Service Dogs On Perceived Organizational Support In Policing, Kenneth M. Quick, Eric L. Piza Sep 2021

Police Officers’ Best Friend?: An Exploratory Analysis Of The Effect Of Service Dogs On Perceived Organizational Support In Policing, Kenneth M. Quick, Eric L. Piza

Publications and Research

This study explored the effectiveness of a novel technique for police departments to support their officers and promote wellness: the use of service dogs. We evaluated officer perceptions in two mid-sized, municipal police departments that have wellness programs with a service dog that is permanently assigned to a full-time police officer handler: Groton and Naugatuck, Connecticut. We assessed 6 factors believed to influence police officer wellness including: operational and organizational stress using the Police Stress Questionnaire (McCreary & Thompson, 2006); topical stressors including those related to the COVID-19 pandemic, police use of force and community relations, and police reform efforts; …


Shooting Surge Continuing To Slow Across New York City, Jeffrey A. Butts, Richard A. Espinobarros Aug 2021

Shooting Surge Continuing To Slow Across New York City, Jeffrey A. Butts, Richard A. Espinobarros

Publications and Research

This report looks at quarter-specific comparisons of police reported shooting incidents across New York City. Shooting incidents increased between the first and second quarters of both 2020 and 2021. However, shooting incident increases slowed between quarters 1 (January-March) and 2 (April-June) in 2021, compared to the same quarters of 2020. Quarter-specific comparisons are one way to address seasonal fluctuations in gun violence.


Measuring Procedural Justice Policy Adherence During Use Of Force Events: The Body-Worn Camera As A Performance Monitoring Tool, Victoria A. Sytsma, Eric L. Piza, Vijay F. Chillar, Leigh S. Grossman Jun 2021

Measuring Procedural Justice Policy Adherence During Use Of Force Events: The Body-Worn Camera As A Performance Monitoring Tool, Victoria A. Sytsma, Eric L. Piza, Vijay F. Chillar, Leigh S. Grossman

Publications and Research

This study capitalizes on a successful researcher–practitioner partnership to conduct a systematic social observation (SSO) of police body-worn camera (BWC) footage in Newark, NJ. To demonstrate the utility of BWCs as performance monitoring tools, we measure officer adherence to procedural justice standards throughout use of force events as mandated in the Newark Police Division’s updated policies pursuant to an ongoing federal consent decree. Overall, a slim majority of use of force events are procedurally just. However, results indicate several instances of policy noncompliance. Results are discussed, and policy recommendations related to procedural justice policy violations and BWCs for performance monitoring …

Analyzing The Spatial Correlates Of Robbery Incidents Displaced By A Place-Based Policing Interventiondisplaced By A Place-Based Policing Intervention, David N. Hatten, Eric L. Piza

Publications and Research

Objective:

Examine the place-based correlates of robbery incidents displaced by a foot-patrol intervention in Newark, NJ. We use constructs from Crime Pattern and Social Disorganization theories to test hypotheses concerned with associations between the structure of the environment and the displacement of crime.

Method:

Robbery incidents were spatially joined to street segments to study micro-level displacement processes. Predictor variables were operationalized using data from the Newark Police Department and Infogroup USA. Generalized Linear models tested associations between the characteristics of street segments and displaced robbery in the target area as compared to a control.

Results:

Environmental structure is important to …


Environmental Factors Influencing Urban Homicide Clearance Rates: A Spatial Analysis Of New York City, Leslie W. Kennedy, Joel M. Caoplan, Eric L. Piza, Amanda L. Thomas Nov 2020

Environmental Factors Influencing Urban Homicide Clearance Rates: A Spatial Analysis Of New York City, Leslie W. Kennedy, Joel M. Caoplan, Eric L. Piza, Amanda L. Thomas

Publications and Research

In this paper, we explore the conditions under which clearance rates improve by looking at the experience across New York City. Using one agency provides a control on the administrative differences that appear across other jurisdictions that have been studied, usually through cross-national analysis. Our analysis uses Risk Terrain Modeling (RTM) to identify environmental features that relate to closed versus open homicide cases using two years of New York City Police Department (NYPD) data. This analysis is supplemented with an investigation of precinct-wide social structure variables to examine how context matters in influencing closure rates.


The Effect Of Program Staffing Difficulties On Changes In Dynamic Risk And Reoffending Among Juvenile Offenders In Residential Placement, Kevin T. Wolff, Katherine E. Limoncelli, Michael T. Baglivio Oct 2020

The Effect Of Program Staffing Difficulties On Changes In Dynamic Risk And Reoffending Among Juvenile Offenders In Residential Placement, Kevin T. Wolff, Katherine E. Limoncelli, Michael T. Baglivio

Publications and Research

Recently there has been growing concern regarding the staffing challenges that plague the U.S. correctional system. This study examines whether staffing challenges within residential facilities are associated with changes in dynamic risk and the likelihood of reoffending among a sample of serious juvenile offenders returning to the community from residential placement. Using administrative data on 2,022 youth who completed a court-imposed placement, in combination with information drawn from a provider’s human resources database, we employ several analytical techniques to untangle the effects of staffing difficulties on youth outcomes. Results indicate that the rate of unscheduled absences was associated with changes …


The Internet Never Forgets: Image-Based Sexual Abuse And The Workplace, John Schriner, Melody Lee Rood Oct 2020

The Internet Never Forgets: Image-Based Sexual Abuse And The Workplace, John Schriner, Melody Lee Rood

Publications and Research

Image-based sexual abuse (IBSA), commonly known as revenge pornography, is a type of cyberharassment that often results in detrimental effects to an individual's career and livelihood. Although there exists valuable research concerning cyberharassment in the workplace generally, there is little written about specifically IBSA and the workplace. This chapter examines current academic research on IBSA, the issues with defining this type of abuse, victim blaming, workplace policy, and challenges to victim-survivors' redress. The authors explore monetary motivation for websites that host revenge pornography and unpack how the dark web presents new challenges to seeking justice. Additionally, this chapter presents recommendations …


The Sensitivity Of Repeat And Near Repeat Analysis To Geocoding Algorithms, Cory P. Haberman, David Hatten, Jeremy G. Carter, Eric L. Piza Sep 2020

The Sensitivity Of Repeat And Near Repeat Analysis To Geocoding Algorithms, Cory P. Haberman, David Hatten, Jeremy G. Carter, Eric L. Piza

Publications and Research

Purpose: To determine if repeat and near repeat analysis is sensitive to the geocoding algorithm used for the underlying crime incident data.

Methods: The Indianapolis Metropolitan Police Department provided 2016 crime incident data for five crime types: (1) shootings, (2) robberies, (3) residential burglaries, (4) theft of automobiles, and (5) theft from automobiles. The incident data were geocoded using a dual ranges algorithm and a composite algorithm. First, descriptive analysis of the distances between the two point patterns were conducted. Second, repeat and near repeat analysis was performed. Third, the resulting repeat and near repeat patterns were compared across geocoding …


Immigrants And Crime, Daniel L. Stageman Jul 2020

Immigrants And Crime, Daniel L. Stageman

Publications and Research

The gap between public perception of immigrant criminality and the research consensus on immigrants’ actual rates of criminal participation is persistent and cross-cultural. While the available evidence shows that immigrants worldwide tend to participate in criminal activity at rates slightly lower than the native-born, media and political discourse portraying immigrants as uniquely crime-prone remains a pervasive global phenomenon. This apparent disconnect is rooted in the dynamics of othering, or the tendency to dehumanize and criminalize identifiable out-groups. Given that most migration decisions are motivated by economic factors, othering is commonly used to justify subjecting immigrants to exploitative labor practices, with …


Measuring The Temporal Stability Of Near-Repeat Crime Patterns: A Longitudinal Analysis, David Hatten, Eric L. Piza May 2020

Measuring The Temporal Stability Of Near-Repeat Crime Patterns: A Longitudinal Analysis, David Hatten, Eric L. Piza

Publications and Research

This study investigates the temporal stability of identified near-repeat robbery patterns in Newark, New Jersey. With one noteworthy exception, scholars have yet to explore the temporal stability of identified spatiotemporal crime clusters. Furthermore, researchers have yet to measure the near-repeat phenomenon longitudinally. To fill this gap, this study employs a longitudinal design to measure variation in effect size and significance of identified near- repeat crime patterns across 13 “rolling” one-year time periods within a 2-year study period (January 2015–December 2016). Temporal instability was found within two out of six spatiotemporal crime clusters. Results are reported in the form of formalized …

Environmental Predictors Of A Drug Offender Crime Script: A Systematic Social Observation Of Google Street View Images And Cctv Footage, Victoria A. Sytsma, Nathan Connealy, Eric L. Piza

Publications and Research

The extent to which environmental context has been considered when developing crime scripts has been limited to descriptions of locations offenders visit during the crime. This research contributes a description of the environmental characteristics of an open-air drug market and identifies environmental facilitators and inhibitors toward offender actions during a drug selling crime script. CCTV camera footage is combined with Google Street View to determine if physical disorder, decay, and ‘crime generators’ characterize the drug market under study. Crime generators such as retail facilities and bars and liquor stores are environmental facilitators toward a drug selling crime script; and transit …


How Can Embedded Criminologists, Police Pracademics, And Crime Analysts Help Increase Police-Led Program Evaluations? A Survey Of Authors Cited In The Evidence-Based Policing Matrix, Eric L. Piza, Json Szkola, Kwan-Lamra Blount-Hill May 2020

How Can Embedded Criminologists, Police Pracademics, And Crime Analysts Help Increase Police-Led Program Evaluations? A Survey Of Authors Cited In The Evidence-Based Policing Matrix, Eric L. Piza, Json Szkola, Kwan-Lamra Blount-Hill

Publications and Research

Evidence-based policing emphasizes the evaluation of interventions to create a catalog of effective programs and practices. Program evaluation has primarily been considered the purview of academic researchers, with police agencies typically uninvolved in the evaluation of their own interventions. Scholars have recently advocated for police to take more ownership over program evaluation, often arguing for an increased role of three primary entities: embedded criminologists, police pracademics, and crime analysts. While an emerging body of literature has explored these entities individually, research has yet to explore the unique contributions each can make to police-led science. The current study is a survey …

Publications and Research

Research Summary:

The current study analyzes the crime reduction effect of a police sub-station operating within a business improvement district in Newark, NJ. Synthetic control methods were used to create a control group that was statistically equivalent to the cumulative street units in the target area. Significant reductions of burglary and motor vehicle theft were observed in the target area as compared to a synthetic control area over the post-intervention period. Robbery and theft from auto, conversely, suffered from spatial displacement. Of the six police actions included in the process evaluation, quality-of-life summonses and directed patrols increased in the post-intervention …

The Criminogenic Effect Of Marijuana Dispensaries In Denver, Colorado: A Microsynthetic Control Quasi-Experiment And Cost-Benefit Analysis, Nathan Connealy, Eric L. Piza, Dave Hatten Dec 2019

The Criminogenic Effect Of Marijuana Dispensaries In Denver, Colorado: A Microsynthetic Control Quasi-Experiment And Cost-Benefit Analysis, Nathan Connealy, Eric L. Piza, Dave Hatten

Publications and Research

The study analyzed the criminogenic effect of legalizing recreational marijuana dispensaries in Denver. Street segments with recreational dispensaries experienced no changes in violent, disorder and drug crime but did experience an 18% increase in property crime, and street segments adjacent to recreational dispensaries experienced some notable (but non-significant) drug and disorder crime increases. Medical dispensaries demonstrated no significant crime changes. A cost-benefit analysis found the associated crime costs were largely offset by sales revenue. Monetary benefits were much less pronounced, and barely cost effective, when only considering tax revenue.


Private Security And Cctv Surveillance: A Systematic Review Of Function And Performance, Brandon C. Welsh, Eric L. Piza, Amanda L. Thomas, David P. Farrington Nov 2019

Private Security And Cctv Surveillance: A Systematic Review Of Function And Performance, Brandon C. Welsh, Eric L. Piza, Amanda L. Thomas, David P. Farrington

Publications and Research

Private security personnel play an important but largely overlooked role in the operation of CCTV surveillance to prevent crime in public and private areas. This role can take a number of forms, including active monitoring of cameras. Drawing upon a global database of CCTV evaluations (N=165), this article examines the function and performance of private security personnel as related to the effectiveness of CCTV. Findings indicate that CCTV schemes operated by private security personnel generated larger crime prevention effects than those operated by police or those using a mix of police and security personnel. Policy and research implications are discussed.


Adherence To The Street Code Predicts An Earlier Anticipated Death, Kevin T. Wolff, Jonathan Intravia, Michael T. Baglivio, Alex R. Piquero Aug 2019

Adherence To The Street Code Predicts An Earlier Anticipated Death, Kevin T. Wolff, Jonathan Intravia, Michael T. Baglivio, Alex R. Piquero

Publications and Research

Objective: Criminologists have long been interested in the relationship between subcultural attitudes and antisocial behavior, with Anderson’s street code thesis being the most recent and often researched foray in this area. Relatedly, scholars have begun to investigate the risk factors associated with the anticipation of early death. Extant research, however, has yet to empirically test Anderson’s hypothesis that subscription to the street code is predictive of an anticipated early death. This study contributes to the literatures on the street code as well as fatalism by investigating the link between these two constructs.

Method: Using data from a sample of serious …


Where Were The Lesbians In The Stonewall Riots? The Women’S House Of Detention & Lesbian Resistance, Polly Thistlethwaite Jun 2019

Where Were The Lesbians In The Stonewall Riots? The Women’S House Of Detention & Lesbian Resistance, Polly Thistlethwaite

Publications and Research

Where were the lesbians in the Stonewall Riots? They were jailed in the House of Detention for Women in Greenwich Village, New York City, two blocks away from the Stonewall Inn. Lesbians in the Women's House of Detention shouted from the windows to the rioters in the streets below, fueling the momentum of the Stonewall uprising. The women's prison was a site of lesbian confinement and resistance that inspired the 1969 uprising in Greenwich Village.

Polly Thistlethwaite is Chief Librarian at the Graduate Center, CUNY. She volunteered at the Lesbian Herstory Archives 1986 – 1997.

Publications and Research

Research Summary: We report on the findings of an updated systematic review and meta-analysis of the effects of closed-circuit television (CCTV) surveillance cameras on crime. The findings show that CCTV is associated with a significant and modest decrease in crime. The largest and most consistent effects of CCTV were observed in car parks. The results of the analysis also demonstrated evidence of significant crime reductions within other settings, particularly residential areas. CCTV schemes incorporating activemonitoring generated larger effect sizes than did passive systems. Schemes deploying multiple interventions alongside CCTV generated larger effect sizes than did schemes deploying single or no …


Risk Factor And High-Risk Place Variations Across Different Robbery Targets In Denver, Colorado, Nathan T. Connealy, Eric L. Piza Nov 2018

Risk Factor And High-Risk Place Variations Across Different Robbery Targets In Denver, Colorado, Nathan T. Connealy, Eric L. Piza

Publications and Research

Purpose

Risk Terrain Modeling (RTM) has been effectively used to spatially diagnose risk for crimes such as robbery, aggravated assault, and gun violence. An important contribution is to consider how risk differs across individual crimes and different target types. This study tests four different robbery target types in unique models to examine the potential for variation across significant risk factors and high-risk locations.

Methods

Using the online diagnostic software RTMDx, individual robbery models were run for four robbery target types in Denver, Colorado: commercial (businesses), carjacking (driver/vehicle), residential (home/dwelling), and street (pedestrians). A conjunctive analysis of case configurations was also …


Crimmigration, Deportability And The Social Exclusion Of Noncitizen Immigrants, Shirley P. Leyro, Daniel L. Stageman Apr 2018

Crimmigration, Deportability And The Social Exclusion Of Noncitizen Immigrants, Shirley P. Leyro, Daniel L. Stageman

Publications and Research

The spread of crimmigration policies, practices, and rhetoric represents an economically rational strategy and has significant implications for the lived experience of noncitizen immigrants. This study draws up in-depth interviews of immigrants with a range of legal statuses to describe the mechanics through which immigrants internalize and respond to the fear of deportation, upon which crimmigration strategies rely. The fear of deportation and its behavioral effects extend beyond undocumented or criminally convicted immigrants, encompassing lawful permanent residents and naturalized citizens alike. This fear causes immigrants to refuse to use public services, endure labor exploitation, and avoid public spaces, resulting in …


Measuring The Effect Heterogeneity Of Police Enforcement Actions Across Spatial Contexts, Eric L. Piza Jan 2018

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 …
