Alabama Sentencing Simulation Model, 1998-2003 (ICPSR 34671)

Released/updated on: 2014-09-30
Geographic coverage: United States, Alabama
Time period: 1970-01-01--2003-12-31

Prior to 2003, the State of Alabama had no formal methodology to forecast prison populations, including a simulation model or statistical time-series and forecasting methods. Instead, the Alabama Department of Corrections relied on percent growth models, using the existing prison population to forecast future statewide prison populations. As Alabama moved toward a structured sentencing system, more precision was needed to investigate the impact statewide sentencing reform would have on the prison population. Adding to the need for more precise forecast methods, the Alabama Sentencing Commission intended to incorporate Virginia worksheet-style sentencing guidelines into its sentencing reform efforts. The Virginia sentencing guidelines uses offender and offense factors identified with statistical models and weights to guide sentence recommendations. Alabama require an analytical tool to guide the Commission during development of such a complicated sentencing system. To shepherd this process, the simulation model development project was undertaken which consisted of three phases;

  • The development of a baseline projection of current practices for later comparison with projections made following implementation of the sentencing standards;
  • Incorporating the initial sentencing standards into the simulation model; and
  • Integrating disparate modules together into a user-friendly model interface.

Applying Artificial Intelligence to Person-Based Policing Practices, 2019-2023 (ICPSR 39074)

Released/updated on: 2024-09-26
Time period: 2019-01-01--2023-12-31
In this project, the research team developed and evaluated an artificial intelligence (AI) tool using agent-based modeling methods for crime analysis and risk evaluation (CARE): CAREsim. The purpose of this tool was to improve the effectiveness of person-based patrol strategies, where police take preemptive actions upon selected high-risk individuals (determined based on factors known to police such as violent crime history) when predicted risks of committing crimes are high. CARESim was developed and tested with a simulated randomized controlled experiment within the jurisdiction of Hampton, Virginia. 240 high-risk individuals (120 in each group) were followed for a 12-month period, with the simulation lasting 23 months. The treatment group received additional crime analyses using the AI tool and more focused patrols, while the control group received analyses as usual and random patrols in the simulated environment. The tool was evaluated on a series of outcomes (e.g., number of crimes and arrests) comparing the control and treatment groups. This collection contains the simulated high-risk individual data (DS1) and the simulated crimes data (DS2) used for the experiment.

Empirical Investigation of "Going to Scale" in Drug Interventions in the United States, 1990, 2003 (ICPSR 26101)

Released/updated on: 2009-08-26
Geographic coverage: United States
Time period: 1990-01-01--1990-12-31, 2003-01-01--2003-12-31
Despite a growing consensus among scholars that substance abuse treatment is effective in reducing offending, strict eligibility rules have limited the impact of current models of therapeutic jurisprudence on public safety. This research effort was aimed at providing policy makers some guidance on whether expanding this model to more drug-involved offenders is cost-beneficial. Since data needed for providing evidence-based analysis of this issue were not readily available, micro-level data from three nationally representative sources were used to construct a 40,320 case synthetic dataset -- defined using population profiles rather than sampled observation -- that was used to estimate the benefits of going to scale in treating drug involved offenders. The principal investigators combined information from the NATIONAL SURVEY ON DRUG USE AND HEALTH, 2003 (ICPSR 4138) and the ARRESTEE DRUG ABUSE MONITORING (ADAM) PROGRAM IN THE UNITED STATES, 2003 (ICPSR 4020) to estimate the likelihood of drug addiction or dependence problems and develop nationally representative prevalence estimates. They used information in the DRUG ABUSE TREATMENT OUTCOME STUDY (DATOS), 1991-1994 (ICPSR 2258) to compute expected crime reducing benefits of treating various types of drug involved offenders under four different treatment modalities. The project computed expected crime reducing benefits that were conditional on treatment modality as well as arrestee attributes and risk of drug dependence or abuse. Moreover, the principal investigators obtained estimates of crime reducing benefits for all crimes as well as select sub-types. Variables include age, race, gender, offense, history of violence, history of treatment, co-occurring alcohol problem, criminal justice system status, geographic location, arrest history, and a total of 134 prevalence and treatment effect estimates and variances.

Improving Officer Decision-Making: Can Personality Predict Outcomes in Use of Force Decisions? North Carolina and South Carolina, 2018-2020 (ICPSR 38687)

Released/updated on: 2024-04-11
Geographic coverage: North Carolina, United States, South Carolina
Time period: 2018-01-01--2020-09-30

The current study sought to examine the impact of select psychological, cognitive, professional experience and social network factors on police officers' decisions to use force. Additionally, the study examined the impact of a brief citizen education intervention (i.e. the completion of police officer training simulations) on citizens' attitudes toward police and use of force. All participants completed three training scenarios inside a firearms training simulator.

A sample of law enforcement officers and civilians took part in the study. Participants completed a series of questionnaires designed to measure, among other things:

  • Positive and Negative Emotionality
  • Need for Cognition
  • Cognitive Reflection
  • Professional experiences as a police officer (law enforcement participants only)
  • Size of friendship networks within the workplace (law enforcement participants only)
  • Perceptions of how their friendship networks would be impacted if the participant were to use excessive force (law enforcement participants only)
  • Pre-post measures of attitudes toward police (civilian participants only)

Investigating the Impact of In-car Communication on Law Enforcement Officer Patrol Performance in an Advanced Driving Simulator in Mississippi, 2011 (ICPSR 34922)

This study used an experimental design to evaluate law enforcement officers' driving, visual attention, and situation awareness during patrol driving. The conditions were varied to determine the impact of information presentation formats on officers' ability to execute patrols. In addition, the effectiveness of in-vehicle technologies that may provide additional support to the officer and reduce the impact of information overload were investigated.
