SAC Works With Law Enforcement to Study the Impact of Drug Market Intervention in Charleston

The West Virginia SAC has been working with the Charleston (WV) Police Department as a research partner to assist with the planning phase and to collect data for evaluating the Drug Market Intervention (DMI) initiative. Funded through the Bureau of Justice Assistance's Byrne Criminal Justice Innovation Program, the DMI initiative is a community- and problem-oriented policing strategy that aims to transform a targeted area into a drug-free, safe community. Recently, the WV SAC designed a community needs assessment survey to assist with planning activities. The survey, approved by the Marshall University Institutional Review Board, will collect responses from the community targeted by the DMI project until October. It includes constructs to measure perceptions of safety, crime issues, and neighborhood concerns; collective efficacy; and community involvement. Survey responses will serve as baseline measures and identify issues to address during the revitalization portion of the project.

SAC Studies Ways to Improve NIBRS Data

The West Virginia SAC is studying techniques to improve data quality in incident-based reporting system (IBRS) focuses on identifying partial-reporting agencies, outlier detection, and imputation methods for estimating missing values. This research is based on the SAC's previous work in which imputation methods showed promising results in improving the accuracy of state National Incident-Based Reporting System (NIBRS) data crime counts. The current research uses longitudinal data to assess the performance of the imputation methods over time. The project aims to examine demonstrated methods, appropriate for state-level data, to provide techniques and a framework for the use of imputation methods that can adequately model uncertainties and provide reliable and stable estimates of crime data over time.
