The Detection of Crime, Resource Deployment, and Predictors of Success: A Multi-Level Analysis of Closed-Circuit Television (CCTV) in Newark, NJ collection represents the findings of a multi-level analysis of the Newark, New Jersey Police Department's video surveillance system. This collection contains multiple quantitative data files (Datasets 1-14) as well as spatial data files (Dataset 15 and Dataset 16). The overall project was separated into three components:

• Component 1 (Dataset 1, Individual CCTV Detections and Calls-For-Service Data and Dataset 2, Weekly CCTV Detections in Newark Data) evaluates CCTV's ability to increase the "certainty of punishment" in target areas;
• Component 2 (Dataset 3, Overall Crime Incidents Data; Dataset 4, Auto Theft Incidents Data; Dataset 5, Property Crime Incidents Data; Dataset 6, Robbery Incidents Data; Dataset 7, Theft From Auto Incidents Data; Dataset 8, Violent Crime Incidents Data; Dataset 9, Attributes of CCTV Catchment Zones Data; Dataset 10, Attributes of CCTV Camera Viewsheds Data; and Dataset 15, Impact of Micro-Level Features Spatial Data) analyzes the context under which CCTV cameras best deter crime. Micro-level factors were grouped into five categories: environmental features, line-of-sight, camera design and enforcement activity (including both crime and arrests); and
• Component 3 (Dataset 11, Calls-for-service Occurring Within CCTV Scheme Catchment Zones During the Experimental Period Data; Dataset 12, Calls-for-service Occurring Within CCTV Schemes During the Experimental Period Data; Dataset 13, Targeted Surveillances Conducted by the Experimental Operators Data; Dataset 14, Weekly Surveillance Activity Data; and Dataset 16, Randomized Controlled Trial Spatial Data) was a randomized, controlled trial measuring the effects of coupling proactive CCTV monitoring with directed patrol units.

Over 40 separate four-hour tours of duty, an additional camera operator was funded to monitor specific CCTV cameras in Newark. Two patrol units were dedicated solely to the operators and were tasked with exclusively responding to incidents of concern detected on the experimental cameras. Variables included throughout the datasets include police report and incident dates, crime type, disposition code, number of each type of incident that occurred in a viewshed precinct, number of CCTV detections that resulted in any police enforcement, and number of schools, retail stores, bars and public transit within the catchment zone.

Crime and other matters of criminal justice were the main focus of inquiry for this Detroit Area Study. Respondents were asked to report on incidents of crime against themselves, relatives, and friends. They also were queried about their fears of being victimized by crime and about measures they had undertaken to protect themselves against crime. In addition, the survey elicited views on wide range of criminal justice issues such as the death penalty, the causes of crime and ways to reduce it, the salience of crime as a social problem, the legalization of marijuana use, handgun laws, the criminality of certain acts such as shooting a fleeing burglar, the construction of new prisons, the imposition of new taxes to improve law enforcement, the allocation of federal funds to police and other services, the activities of the police and courts including their fairness toward blacks, and whether or not convicting the innocent was better than letting the guilty go free. The survey also sought respondents' views on other social issues, such as prayer in public schools, labor unions, the Equal Rights amendment, defense spending, abortion, the quality of public schools, and affirmative action. Additional information gathered by the survey includes duration of residence in the tri-county area and at the current address, place of previous residence, moves planned for the future, television viewing habits, which newspapers were read, gun ownership, shopping habits, home and motor vehicle ownership, use of public transportation, travel to work, political and social class affiliation, satisfaction with neighborhoods and with the tri-county area, and information on age, sex, place of birth, marital status, education, employment, occupation, income, religion, race, ethnicity, and household composition.

These data are part of NACJD's Fast Track Release and are distributed as they were received from the data depositor. The files have been zipped by NACJD for release, but not checked or processed except for the removal of direct identifiers.

This study, through a national survey and field studies in both patrols and investigations, examined the crime control and cost-effectiveness of the use of license plate readers (LPRs) within police agencies in the United States.

The collection contains 1 SPSS data file (Data-file-for-2013-IJ-CX-0017.sav (n=329; 94 variables)).

A demographic variable includes an agency's number of authorized full time personnel.

This study examined the effects of comprehensive registration and community notification policies on rates of sexual violence in South Carolina. Specifically, it proposed to (1) evaluate whether broad sex offender registration and notification policies have reduced recidivism or deterred new sexual offenses, (2) examine whether unintended effects of broad registration and notification policies occurred, and (3) focus on the effects of registration and notification as it pertained to offenses committed by adults. The study examined whether the introduction of sex offender registration and notification laws in South Carolina were associated with reductions in sexual crimes and, if so, whether this reduction could be attributed to an actual reduction in sexual violence and/or recidivism (i.e., an intended effect) or to changes in criminal judicial processing of individuals for registry crimes (i.e., an unintended effect).

Specific study aims included examining whether: (1) South Carolina registration and notification policies had the intended effect of preventing first time sexual offending; (2) South Carolina registration and notification policies had the intended effect of reducing sexual recidivism for known sex offenders; and (3) South Carolina registration and notification policies had the unintended effect of reducing the probability that individuals who committed sexual crimes would be prosecuted or convicted for such crimes. In addition to these primary aims, the researchers also investigated (4) registration violations (e.g., failure to register) were associated with sexual or general recidivism.

This project investigated the experiences of New York City youth ages 16-24 who were at high risk for gun violence (e.g., carried a gun, been shot or shot at). Youth participants were recruited from three neighborhoods with historically high rates of gun violence when compared to the city as a whole--Brownsville (Brooklyn), Morrisania (Bronx), and East Harlem (Manhattan). This study explores the complex confluence of individual, situational, and environmental factors that influence youth gun acquisition and use. This study is part of a broader effort to build an evidence-based foundation for individual and community interventions, and policies that will more effectively support these young people and prevent youth gun violence. Through interviews with 330 youth, this study seeks to answer these questions:

1. What are the reasons young people carry guns?
2. How do young people talk about having and using guns?
3. What are young people's social networks like, and what roles do guns play in thesenetworks?

Interviews covered the following topics: neighborhood perceptions; perceptions of and experiences with the police, gangs, guns, and violence; substance use; criminal history; and demographics: race, gender, age, legal status, relationship status, living situation, location, number of children, drug use, and education.
