This paper presents the first attempt to integrate four distinct approaches to solving crimes, all of which have proven their value when applied independently, namely: (1) geographic assessment, (2) social networking, (3) crime pattern analysis, and (4) physical description match. The system that integrates these four search techniques, called PerpSearch, takes a description of the crime, including its locations and all other known aspects (e.g., physical characteristics of suspects, vehicles, etc.), and runs it all through the PerpSearch engine components, where they are combined to produce a score for each potential suspect. By using past data on crimes prior to solution and comparing the results against the eventual known perpetrators, the system can be fine tuned and validated. A prototype has been implemented using current Alabama criminal and demographic databases.
IRAS: An Inmates’ Risk Assessment System
June 1, 2009 Health and Human Services, Law EnforcementLi Ding, Brandon Dixon, Allen Parrish, International Journal of Computers and Their Applications, Vol. 16, No. 2, June 2009
This research had the goal of improving the classification of offenders into their different levels of risk in order to improve the decision-making process with regard to diversion programs (i.e., alternatives to incarceration). The system is based on an automated assessment of the likelihood of recidivism based on nine weighted attributes. The system can easily be tested by running it on past historical data and then comparing the results with the observation of more recent outcomes. This was pilot tested using data from Madison County, Alabama.
Analysis of the Wet vs. Dry Counties within Alabama (pdf)
January 31, 2009 Analytics, Health and Human Services, Law EnforcementBrown, D., CAPS Research Report, Jan. 31, 2009.
CARE IMPACT analyses were performed to compare 13 dry counties with 13 wet counties over their various crash characteristics for a recent five-year (2003-2007) time period. The results fall into two logical categories: those that compare the demographics of the counties and those that compare the crash characteristics with regard to alcohol. A few of the nearly 200 attribute comparisons are presented in this report in order to guide the future direction of the research project.
Alcohol Age Crash Analysis – Projections of the Effect of Lowering the Legal Drinking Age in Alabama (pdf)
August 16, 2008 Analytics, Health and Human Services, Law EnforcementBrown, D., CAPS Research Report, Aug. 16, 2008.
This report, and the Op Ed that follows it, is in response to a number of prominent college presidents who have recently come out in favor of lowering the drinking age to 18 years. The goal of the report is to project how many additional fatalities will be caused in Alabama should the law be change in Alabama.
