To assess the current practices in cold-case investigations, this study utilized a national online survey of law enforcement agencies (Cold Case Survey Data, n = 1,051) to document the range of ways in which cold-case work is conducted and assess how this organization affects cold-case clearance rates. In November 2008, the chiefs of police in the sample were sent a letter explaining the purpose of the survey and inviting them to participate. Potential respondents were directed to the web-based survey instrument through a provided web address. The results from the national survey were used to select sites for an analysis of case files. Researchers chose three jurisdictions that conducted a large number of cold-case homicide investigations: the District of Columbia, Baltimore, Maryland, and Dallas, Texas (Cold Case Homicide Data, n = 429). To these three sites, researchers added Denver, Colorado (Cold Case Sexual Assault Data, n = 105) because it had received a Department of Justice grant to conduct testing of DNA material in sexual assault cold cases. At all four sites, cold cases were examined for seven categories of data including victim's characteristics, crime context, motivation, human capital, physical evidence, basis for cold-case investigations and cold-case actions.

This study examined the implementation of a pilot parole-based intervention, known as the Next Generation of Parole Supervision (NG). Drs. Caleb Lloyd and Ralph Serin developed the NG model with funding from the National Institute of Justice (NIJ), and the National Institute of Corrections developed the NG curriculum for parole officers to implement. The Bureau of Justice Assistance funded the implementation of NG in three study sites: Dallas, Texas; Denver, Colorado; and Des Moines, Iowa.
This mixed-methods study focused on understanding how NG was implemented as it was piloted in the three sites, and assessed NG-trained parole officers' fidelity to the NG model. In order to better understand NG's implementation and the business as usual practices it was intended to replace, the study also included a second group of parole officers who were not trained in NG. The groups were not randomly assigned. Data collected for this study included interview data, parole officer questionnaires related to concepts of the NG curriculum, coaching logs providing measures of whether officers received coaching and its frequency, video recordings of parole supervision meetings, and parole caseload data.
Demographic variables included as part of this collection are parole officers' age and sex, and site location. The data collection includes 3 SAS data files:
- Parole officer-level data (archive_raf170831_po): Includes 31 cases and 26 variables.
- Video-level data (archive_raf170831_video): Includes 241 cases and 15 variables.
- Questionnaire-level data (archive_raf180719_tests): Includes 50 cases and 8 variables.

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:
- Collecting official data on crime related to the underground weapons and drugs economies
- Conducting semi-structured interviews with convicted traffickers, pimps, child pornographers, and sex workers at the federal, state, and local levels
- 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.

These data were collected as part of an effort to gain a more in depth understanding of the processes surrounding disengagement from a youth gang, and come from structured interviews with their parent or guardian. The interview included such topics as parental monitoring practices, attitudes about the youth's peer group, and perceptions about the neighborhood. Study participants lived in seven geographically diverse cities in the United States, making it one of few multi-site studies of gangs or gang members.

The goal of the study was to determine what effect, if any, the Gang Resistance Education and Training (G.R.E.A.T.) program had on students. The G.R.E.A.T., a 13-lesson general prevention program taught by uniformed law enforcement officers to middle school students, had three stated goals: 1) to reduce gang membership, 2) to reduce delinquency, especially violent offending, and 3) to improve students' attitudes toward the police.
To assess program effectiveness, researchers conducted a randomized control trial involving 3,820 students nested in 195 classrooms in 31 schools in 7 cities. A process evaluation consisted of multiple methods to assess program fidelity: 1) observations of G.R.E.A.T. Officer Trainings, 2) surveys and interviews of G.R.E.A.T.-trained officers and supervisors, 3) surveys of school personnel, and 4) "on-site," direct observations of officers delivering the G.R.E.A.T. program in the study sites. Only the data from the student surveys, law enforcement officer surveys, and school personnel surveys are available.
Data file 1 (Student Survey Data) has 3,820 cases and 1,926 variables. Data file 2 (Law Enforcement Survey Data) has 137 cases and 140 variables. Data file 3 (School Personnel Survey Data) has 230 cases and 148 variables.

This multi-method, multi-site study aimed to increase scientific knowledge on the population size, needs, characteristics, and criminal justice experiences of youth who are involved in exchanging sex for money, food, housing, drugs, or other goods. Youth interviews were conducted in each of six geographically diverse research sites, as well as interviews with social service and law enforcement agency staff in four of the sites. In addition, state-level data on prostitution arrests of youth under the age of 18 and case-level data on prostitution arrests of youth under the age of 24 in the six research sites were obtained, but are not included in this collection.
The collection includes one SPSS data file, Youth_in_the_Sex_Trade_Final_Quantitative_Dataset.sav (n=949, vars= 88).
The qualitative data are not available as part of this collection at this time.
