The current study sought to expand the current understanding of the psychometric characteristics of the collective efficacy scale at the individual level and the role of collective efficacy in promoting safe, healthy community conditions. A team of interviewers consisting of residents of the targeted neighborhoods were selected and trained to administer the field surveys (NIJ Neighborhoods Resident Survey Data, 108 variables, n=649). In order to ensure accuracy of the responses, the field supervisor conducted telephone validation for approximately ten to fifteen percent of the surveys. In addition to resident surveys, trained research staff conducted systematic social observations (SSOs) of street segments in selected neighborhoods noting physical and social indictors.

This study measures the size and structure of the underground commercial sex economy in eight major US cities: San Diego, Seattle, Dallas, Denver, Washington, DC, Kansas City, Atlanta, and Miami. The goals of this study were to derive a more rigorous estimate of the underground commercial sex economy (UCSE) in eight major US cities and to provide an understanding of the structure of this underground economy.

Researchers relied on a multi-method approach using both qualitative and quantitative data to estimate the size of UCSE including:

1. Collecting official data on crime related to the underground weapons and drugs economies
2. Conducting semi-structured interviews with convicted traffickers, pimps, child pornographers, and sex workers at the federal, state, and local levels
3. Conducting semi-structured interviews with local and federal police investigators and prosecutors to inform our analysis of the interrelationship across different types of underground commercial sex activity.

This study was a systematic assessment of the impacts of foreclosures and crime levels on each other, using sophisticated spatial analysis methods, informed by qualitative research on the topic. Using data on foreclosures and crime in District of Columbia and Miami-Dade County, Florida from 2003 to 2011, this study considered the effects of the two phenomena on each other through a dynamic systems approach.

The purpose of the study was to examine whether and how foreclosures affect neighborhood crime in five cities in the United States. Point-specific crime data was provide by the New York (New York) Police Department, the Chicago (Illinois) Police Department, the Miami (Florida) Police Department, the Philadelphia (Pennsylvania) Police Department, and the Atlanta (Georgia) Police Department. Researchers also created measures of violent and property crimes based on Uniform Crime Report (UCR) categories, and a measure of public order crime, which includes less serious offenses including loitering, prostitution, drug crimes, graffiti, and weapons offenses. Researchers obtained data on the number of foreclosure notices (Lis Pendens) filed, the number of Lis Pendens filed that do not become real estate owned (REO), and number of REO properties from court fillings, mortgage deeds and tax assessor's offices.

This study examines the state of counterterrorism and homeland security in five large urban law enforcement agencies (the Boston Police Department, the Houston Police Department, the Las Vegas Metropolitan Police Department, the Los Angeles County Sheriff's Department, and the Miami-Dade Police Department) nine years following the September 11, 2001, terrorist attacks. It explores the long-term adjustments that these agencies made to accommodate this new role.

Researchers from the RAND Corporation, in consultation with National Institute of Justice project staff, selected law enforcement agencies of major urban areas with a high risk of terrorist attacks from different regions of the United States that have varied experiences with counterterrorism and homeland security issues. The research team conducted on-site, in-depth interviews with personnel involved in developing or implementing counterterrorism or homeland security functions within their respective agency. The research team used a standardized interview protocol to address such issues as security operations, regional role, organizational structures, challenges associated with the focus on counterterrorism and homeland security issues, information sharing, training, equipment, and grant funding.

In 2015, Miami-Dade County Public Schools (M-DCPS) received a three-year Comprehensive School Safety Initiative grant from the National Institute of Justice to implement, pilot test, and experimentally evaluate the effects of an innovative fusion center, Campus Shield, for proactively identifying and addressing school safety threats and issues. Three additional resources were also proposed to supplement and enhance the Campus Shield fusion center: visitor management systems (information on entries and exits from the school building to be recorded and fed into Campus Shield), surveillance cameras (which would also feed into Campus Shield), and the linkage of Campus Shield to "Mental Health Specialists" to provide direct services and act as a liaison between school-based student services professionals and community-based providers.

This study contains Uniform Crime Report geocoded data obtained from St. Petersburg Police Department, Orlando Police Department, and Miami-Dade Police Department for the years between 2010 and 2014. The three primary goals of this study were:

1. to determine whether Florida law HB 7095 (signed into law on June 3, 2011) and related legislation reduced the number of pain clinics abusively dispensing opioid prescriptions in the State
2. to examine the spatial overlap between pain clinic locations and crime incidents
3. to assess the logistics of administering the law

The study includes:

• 3 Excel files: MDPD_Data.xlsx (336,672 cases; 6 variables), OPD_Data.xlsx (160,947 cases; 11 variables), SPPD_Data.xlsx (211,544 cases; 14 variables)
• 15 GIS Shape files (95 files total)

This project examined practices and initiatives undertaken by prosecutors across the United States to address trafficking in persons (TIP) in order to learn about TIP case identification and case building; when jurisdictions prosecute utilizing their state's TIP statute or alternative charges; and how prosecutors approach victim identification, serving victims, and increasing convictions and penalties for traffickers and buyers. It also sought to draw lessons learned that other jurisdictions can use to begin this work or increase their capacity and effectiveness, regardless of size or location. This project was a partnership between the Justice Research and Statistics Association (JRSA) and the National District Attorney's Association (NDAA) and consisted of two phases. Phase I was a national survey of prosecutors and Phase II was a series of four case studies in jurisdictions undertaking anti-TIP initiatives.

The results of the survey are intended to provide a national snapshot of trends in local TIP prosecutions and the use of state-level TIP statutes by local prosecutors. It serves as a ten-year update to, and expansion of, previous research on local prosecutorial approaches to trafficking that had used data on cases prosecuted through 2008.

This collection includes data gathered through three separate study designs. The first study called for tracking cases and forensic evidence through local criminal justice processes for five offenses: homicide, sexual assault, aggravated assault, robbery and burglary. Two sites, Denver, Colorado, and San Diego, California, participated in the study. Demographic data were collected on victims (Victim Data n = 7,583) and defendants (Defendant Data n = 2,318). Data on forensic evidence collected at crime scenes included DNA material (DNA Evidence Data n = 1,894), firearms evidence (Ballistics Evidence Data n = 488), latent prints (Latent Print Evidence Data n = 766), trace evidence (Other Impressions Evidence Data n = 49), and drug evidence (Drug Evidence Data n = 43). Comparisons were then made between open and closed cases from the participating sites. Two smaller studies were conducted as part of this grant. The second study was an analysis of an experiment in the Miami-Date, Florida Police Department (Miami-Data County Data n = 1,421) to determine whether clearance rates for no-suspect property crimes could be improved through faster processing of DNA evidence. The third study was a survey of 75 police departments across the nation (Crime Labs Survey Data) to obtain information on the organizational placement, staffing and responsibilities of crime lab units.
