This 2020 study was funded by the National Institute of Justice to advance knowledge about the microscopical methods used to examine materials commonly found in commercial and improvised low explosives. To achieve this, researchers developed reference documentation and an "Atlas of Unburned, Partially Burned, and Fully Burned Low Explosive and Related Materials" for the characterization, comparison, and identification of such materials. This data collection includes 57 files with images and descriptive captions documenting methods of microscopical analysis for a variety of chemically reacted, improvised low explosives and related residues. Details on the optical and physical properties, information regarding chemical solubility, recrystallization, microcrystal and microchemical spot tests, melting points, potential decomposition products, references, and photomicrographs of these materials are included as a PDF table. Additional information on this research can be found on the McCrone Research Institute website.

The purpose of the study was to examine: (1) which entities pay for sexual assault medical forensic exams (MFEs) in state and local jurisdictions throughout the United States, and the policies and practices around determining payment; (2) what services are provided in the exam process and how exams are linked to counseling, advocacy, and other services; (3) whether exams are provided to victims regardless of their reporting or intention to report the assault to the criminal justice system; (4) how MFE kits are being stored for victims who choose not to participate in the criminal justice system process; and (5) whether Violence Against Women Act (VAWA) 2005 requirements are generally being met throughout the country.

Researchers conducted national surveys to obtain state-level information from state Services Training Officers Prosecutors (STOP) administrators (SSAs), victim compensation fund administrators, and state-level sexual assault coalitions. Surveys were distributed to potential respondents in all 50 states, the District of Columbia, and United States territories that held these state-level positions. Researchers also distributed local-level surveys though an extensive listserv maintained by the National Sexual Violence Resource Center (NSVRC). Researchers also conducted case studies in 19 local jurisdictions across six states were selected for case studies.

Interviewees included

• the victim compensation fund administrator, state STOP administrator, state coalition director (or an appointed staff member) and sometimes crime lab or other state justice agency personnel, at the state level, and;
• law enforcement, prosecution, victim advocacy staff, and healthcare-based exam providers at the local level.

Finally, researchers concluded each local jurisdiction visit with a focus group with victims of sexual assault.

Data collection efforts included: a national survey of crime victim compensation fund administrators (Compensation Data, n = 26); a national survey of Services Training Officers Prosecutors (STOP) grant program administrators (SSA Data, n = 52); a national survey of state sexual assault coalitions (Coalitions Data, n = 47); and a survey of local community-based victim service providers (Local Provider Data, n = 489).

The National Institute of Justice (NIJ) and the Office for Violence Against Women (OVW) has evaluated the implementation process and impact of the U.S. Department of Justice's Domestic Violence Homicide Prevention Demonstration Initiative. The evaluation was conducted by a team of investigators from Yale University and Michigan State University.

The demonstration initiative (DI) included 3 implementation sites (California, North Carolina and Illinois). In addition, 2 comparison or typically implementing sites (Michigan and Tennessee) were included in the evaluation. The sites implemented the Lethality Assessment Program (LAP) developed by the Maryland Network Against Domestic Violence.

A web-based survey was used to gather data to assess changes in collaboration within each of the sites. Respondents from agencies providing support to victims of domestic violence and their offenders reported on their level of collaboration with other named agencies in their networks at two or three time points. Data sets are at the site level. Social network analysis was conducted to assess how the network changes over time.

This project sought to understand the effects of successive drug policy reforms in the state of Oregon. These include three changes since 2013 to reduce the enforcement and punishment of low-level drug possession. House Bill 3194 passed in 2013, which reduced mandatory minimum sentences for marijuana offenses and diverted more driving and drug-related offenses to probation. House Bill 2355 passed in 2017, which reclassified Schedule I and II possession of controlled substance (PCS), reducing these from a moderate felony to a misdemeanor. Then in 2021, M110 was implemented, downgrading certain quantities of PCS from a misdemeanor to a citation, resulting in a maximum 100 dollar fine or completed health assessment.

The researchers conducted a retrospective longitudinal analysis using statewide administrative data to assess the impacts of these drug law reforms. Measures included police stops, PCS arrests, court filings, convictions, jail and prison admissions, crime rates, drug seizures, and drug-related overdose deaths.

The California correctional system underwent a dramatic transformation under California's Public Safety Realignment Act (AB 109) in 2011, a law that shifted from the state to the counties the responsibility for monitoring, tracking, and incarcerating lower level offenders previously bound for state prison. Realignment, therefore, presents the opportunity to witness 58 natural experiments in the downsizing of prisons. Counties faced different types of offenders, implemented different programs in different community and jail environments, and adopted differing sanctioning policies. This study examines the California's Public Safety Realignment Act's effect on counties' criminal justice institutions, including the disparities that result in charging, sentencing, and resource decisions.

This project set out to understand the specific contributions Alaska's village public safety officers (VPSOs) make to the criminal justice responses to violence committed against Alaska Native and American Indian women in Alaska's tribal communities. More specifically, the goal of this study was to empirically document and assess the impact Alaska's VPSO program has on the investigation and prosecution of those who commit acts of sexual and domestic violence against Alaska Native and American Indian women in Alaska's tribal communities.

The data collected for this study were compiled from detailed case record reviews of a random sample of sexual assault, sexual abuse of a minor, and domestic violence incidents investigated by the Alaska State Troopers (AST) and closed between January 1, 2008 and December 31, 2011. Data pertaining to case-level (e.g., year and month of incident report and case closure, time to report) and incident-level (e.g., assault location, weapon use, assaultive behaviors) characteristics were collected, as were demographic data describing suspects, victims, and witnesses/third parties. The study also collected data detailing suspect and victim alcohol/drug use and intoxication, injuries sustained by victims, victim resistance strategies and behaviors, and victim disclosures, among other measures. Additional charging and case resolution (referral, prosecution, conviction) data were also compiled. Finally, the study collected detailed data on the activities and roles played by VPSOs in investigations, as well as additional follow-up activities and services provided to victims.

In total, 683 sexual assault (SA) and sexual abuse of a minor (SAM) and 982 domestic violence (DV) case records were coded and analyzed.

The study collections includes 6 Stata (.dta) files. The zip file includes 2013-VW-CX-0001_DV_CASE.dta (n=982; 127 variables), 2013-VW-CX-0001_DV_CHARGE.dta (n=3711; 23 variables), 2013-VW-CX-0001_DV_INDIV.dta (n=3747; 105 variables), 2013-VW-CX-0001_SA_CASE.dta (n=683; 133 variables), 2013-VW-CX-0001_SA_CHARGE.dta (n=1060; 24 variables), 2013-VW-CX-0001_SA_INDIV.dta (n=3140; 112 variables).

In 1953, Congress enacted Public Law 280, transferring federal criminal jurisdiction in Indian country to the state government in six states, allowing other states to join in at a later date. This study was designed to gain a better understanding of law enforcement under Public Law 280. Specifically, amid federal concerns about rising crime rates in Indian country and rising victimization rates among Indians, the National Institute of Justice funded this study to advance understanding of this law and its impact, from the point of view of tribal members as well as state and local officials.

The research team gathered data from 17 confidential reservation sites, which were selected to ensure a range of features such as region and whether the communities were in Public Law 280 jurisdictions under mandatory, optional, excluded, straggler, or retroceded status. Confidential interviews were conducted with a total of 354 reservation residents, law enforcement officials, and criminal justice personnel. To assess the quality or effectiveness of law enforcement and criminal justice systems under Public Law 280, the research team collected quantitative data pertaining to the responsiveness, availability, quality, and sensitivity of law enforcement, and personal knowledge of Public Law 280.

The National Initiative for Building Community Trust and Justice (the National Initiative) is a joint project of the National Network for Safe Communities, the Center for Policing Equity, the Justice Collaboratory at Yale Law School, and the Urban Institute, designed to improve relationships and increase trust between communities and law enforcement.

Funded by the Department of Justice, this mixed-methods evaluation aimed to assess outcomes and impacts in six cities that participated in the National Initiative, which include Birmingham, AL; Fort Worth, TX; Gary, IN; Minneapolis, MN; Pittsburgh, PA; and Stockton, CA. The data described herein represent two waves of surveys of residents living in the highest-crime, lowest-income residential street segments in the six National Initiative cities.

The first wave was conducted between September 2015 and January 2016, and the second wave was conducted between July and October 2017. Survey items were designed to measure neighborhood residents' perceptions of their neighborhood conditions--with particular emphases on neighborhood safety, disorder, and victimization--and perceptions of the police as it relates to procedural justice, police legitimacy, officer trust, community-focused policing, police bias, willingness to partner with the police on solving crime, and the law.

The data described herein are from pre- and post-training assessment surveys of officers who participated in three trainings: 1) procedural justice (PJ) conceptual training, which is the application of PJ in the context of law enforcement-civilian interactions, as well as its role in mitigating historical tensions between law enforcement and communities of color; 2) procedural justice tactical, which provided simulation and scenario-based exercises and techniques to operationalize PJ principles in officers' daily activities; and 3) implicit bias, which engaged officers in critical thought about racial bias, and prepared them to better identify and handle identity traps that enable implicit biases. Surveys for the procedural justice conceptual training were fielded between December 2015 and July 2016; procedural justice tactical between February 2016 and June 2017; and implicit bias between September 2016 and April 2018. Survey items were designed to measure officers' understanding of procedural justice and implicit bias concepts, as well as officers' levels of satisfaction with the trainings.

Within the past fifteen years, policymakers across the country have increasingly supported criminal justice reforms designed to reduce the scope of mass incarceration in favor of less costly, more evidence-based approaches to preventing and responding to crime. One of the primary reform efforts is the Justice Reinvestment Initiative (JRI), a public-private partnership through which state governments work to diagnose the primary drivers of their state incarceration rates, reform their sentencing policies to send fewer nonviolent offenders to prison, and reinvest the saved money that used to go into prisons into alternatives to incarceration, instead.

This mixed-methods study sought to assess public opinion about the justice reinvestment paradigm of reform and to determine whether exposure to racialized and race-neutral cues affects people's willingness to allocate money into criminal justice institutions versus community-based social services in order to reduce and prevent crime.

This study, Responding to Sexual Assault on Campus: A National Assessment and Systematic Classification of the Scope and Challenges for Investigation and Adjudication, documents the current landscape (the breadth and differences) of campus approaches to investigations and adjudication of sexual assault. Data were gathered from a national sample of 969 colleges and universities in conjunction with interviews with key informants in 47 universities.

Informed by a victim-centered focus, researchers developed a typology/matrix of approaches based on documented features of Institutes of Higher Education (IHE) policies related to sexual assault. In addition to the typology/matrix development, interviews and surveys of campus stakeholders and key informants were conducted to identify implementation strategies and challenges associated with each type of response model. The project ultimately produced guidelines that may assist colleges with assessing their capacity and preparedness to meet new and existing demands for sexual assault response models.

This study contains data from a web-based survey focusing on the impact of various factors on knowledge translation, barriers to knowledge translation, and facilitators of knowledge translation. The respondents comprised of critical state agency and legislative practitioners and policymakers and academic researchers in adult and juvenile corrections. Respondents were asked to estimate the extent to which adult and juvenile correctional policy and practice were influenced by research, and to identify the common pathways where research impacts policy.

The study includes one Stata data file: survey_nij_submission.dta (19 cases; 51 variables).

Data related to respondents' qualitative interviews are not available as part of this collection.

This study was conducted to address the dropping rates in residential placements of adjudicated youth after the 1990s. Policymakers, advocates, and reseraches began to attirbute the decline to reform measures and proposed that this was the cause of the drop seen in historic national crime. In response, researchers set out to use state-level data on economic factors, crime rates, political ideology scores, and youth justice policies and practices to test the association between the youth justice policy environment and recent reductions in out-of-home placements for adjudicated youth.

This data collection contains two files, a multivariate and bivariate analyses. In the multivariate file the aim was to assess the impact of the progressive policy characteristics on the dependent variable which is known as youth confinement. In the bivariate analyses file Wave 1-Wave 10 the aim was to assess the states as they are divided into 2 groups across all 16 dichotomized variables that comprised the progressive policy scale: those with more progressive youth justice environments and those with less progressive or punitive environments. Some examples of these dichotomized variables include purpose clause, courtroom shackling, and competency standard.
