Children as Citizens: Engaging Adolescents in Research on Exposure to Violence

January 2011

Since the adoption of the United Nations Convention on the Rights of the Child in 1989, great strides have been made in the areas of child protection and advocacy. However, the concept of children, and specifically adolescents, as functional and engaged citizens has also emerged. Through the guidance and recognition of adults, children can participate in deliberative democracy as legitimate and competent citizens. This citizenship, like that of adults, can be used to enrich and improve local communities by creating a sense of ownership and fairness. Dr.

Less Prison, More Police, Less Crime: How Criminology Can Save the States from Bankruptcy

April 2010

Professor Lawrence Sherman explains how policing can prevent far more crimes than prison per dollar spent. His analysis of the cost-effectiveness of prison compared to policing suggests that states can cut their total budgets for justice and reduce crime by reallocating their spending on crime: less prison, more police.

Legitimacy and Community Cooperation With Law Enforcement

August 2009

Tom R. Tyler, chair of the New York University psychology department, describes research on profiling and community policing. His research found that citizens of all races show greater respect for law enforcement when they believe officers are treating them fairly. Even citizens who experienced a negative outcome getting a traffic ticket, for example showed higher levels of respect for and cooperation with law enforcement as long as they believed they were not being singled out unfairly.

How Collaboration Between Researchers and Police Chiefs Can Improve the Quality of Sexual Assault Investigations: A Look at Los Angeles

June 2011

Panelists discuss the application of research findings from an NIJ-sponsored study of sexual assault attrition to police practice in Los Angeles. There are three main focal points: (1) the mutual benefits of researcher/practitioner partnerships, (2) the implications of variation in police interpretation of UCR guidelines specific to clearing sexual assault (with an emphasis on cases involving nonstrangers), and (3) the content of specialized training that must be required for patrol officers and detectives who respond to and investigate sex crimes.

From the Academy to Retirement: A Journey Through the Policing Lifecycle

December 2009

Professor Rosenbaum and a panel of colleagues discuss a study to demonstrate the feasibility of creating a foundation from which to launch studies about multiple aspects of policing using standardized definitions and measurement tools. Their goal is to advance knowledge about policing and translate data into evidence-based best practices that improve training, supervision and accountability systems. The effort is expected to produce a better understanding of what motivates police officers and makes them healthier, happier and more effective.

Don't Jump the Shark: Understanding Deterrence and Legitimacy in the Architecture of Law Enforcement

November 2010

Deterrence theory dominates the American understanding of how to regulate criminal behavior but social psychologists' research shows that people comply for reasons that have nothing to do with fear of punishment; they have to do with values, fair procedures and how people connect with one another. Professor Meares discussed the relevance of social psychologists' emerging theory to legal theory and practice and how deterrence and emerging social psychology theories intertwine.

Reforming New Orleans' Criminal Justice System: The Role of Data and Research

September 2012

With its criminal justice system in disarray following Hurricane Katrina, New Orleans invited the Vera Institute of Justice to examine the city's court and jail operations. For five years, Vera has been tracking arrest-to-first-appearance time, custodial arrests versus summonses, the granting of pretrial release, and many other decision-making points. Based on analysis of these data, Vera is making policy recommendations to assist with the implementation of new procedures and to ensure performance monitoring.

The State of the Police Field: A New Professionalism in Policing?

June 2010

Panelists debate the premise of a Harvard Executive Session working paper that suggests police organizations are striving for a "new" professionalism. Leaders are endeavoring for stricter standards of efficiency and conduct, while also increasing their legitimacy to the public and encouraging innovation. Is this new? Will this idea lead to prematurely discarding community policing as a guiding philosophy?
