Item Does Feminist Theory Matter?(Oxford University Press, 2015) Petersen, Amanda; Salisbury, Emily; Sundt, JodyItem Text Mining for Social Harm and Criminal Justice Applications(2020-08) Pandey, Ritika; Mohler, George; Hasan, Mohammad Al; Mukhopadhyay, SnehasisIncreasing rates of social harm events and plethora of text data demands the need of employing text mining techniques not only to better understand their causes but also to develop optimal prevention strategies. In this work, we study three social harm issues: crime topic models, transitions into drug addiction and homicide investigation chronologies. Topic modeling for the categorization and analysis of crime report text allows for more nuanced categories of crime compared to official UCR categorizations. This study has important implications in hotspot policing. We investigate the extent to which topic models that improve coherence lead to higher levels of crime concentration. We further explore the transitions into drug addiction using Reddit data. We proposed a prediction model to classify the users’ transition from casual drug discussion forum to recovery drug discussion forum and the likelihood of such transitions. Through this study we offer insights into modern drug culture and provide tools with potential applications in combating opioid crises. Lastly, we present a knowledge graph based framework for homicide investigation chronologies that may aid investigators in analyzing homicide case data and also allow for post hoc analysis of key features that determine whether a homicide is ultimately solved. For this purpose we perform named entity recognition to determine witnesses, detectives and suspects from chronology, use keyword expansion to identify various evidence types and finally link these entities and evidence to construct a homicide investigation knowledge graph. We compare the performance over several choice of methodologies for these sub-tasks and analyze the association between network statistics of knowledge graph and homicide solvability.Item Understanding Law Enforcement Intelligence Processes: Report to the Office of University Programs, Science and Technology Directorate(U.S. Department of Homeland Security, 2014) Carter, David L.; Chermak, Steven; Carter, Jeremy G.; Drew, JackDespite clear evidence of significant changes, very little research exists that examines issues related to the intelligence practices of state, local, and tribal (SLT) law enforcement agencies. Important questions on the nature of the issues that impact SLT intelligence practices remain. While there is some uncertainty among SLT law enforcement about current terrorism threats, there is certainty that these threats evolve in a largely unpredictable pattern. As a result there is an ongoing need for consistent and effective information collection, analysis and sharing. Little information is known about perceptions of how information is being shared between agencies and whether technologies have improved or hurt information sharing, and little is known about whether agencies think they are currently prepared for a terrorist attack, and the key factors distinguishing those that think they are compared to those who do not. This study was designed to address these issues, and a better understanding of these issues could significantly enhance intelligence practices and enhance public safety.Item Violent Injury Recidivism Among Urban Assault Victims: A 10-year Cohort Study(APHA, 2018-11) Magee, Lauren A.; Aalsma, Matthew; Gharbi, Sami; Wiehe, Sarah E.; Pediatrics, School of Medicine
