and Education, through its Committee on Law and Justice, established the Panel on the Understanding and Control of Violent Behavior and took primary responsibility for shaping the specific mandate and composition of the panel. Two features of its mandate carried particular weight. First, to draw implications from past research and to chart its future course, the perspectives and models of biological, psychological, and social science research on violence should be integrated. Second, as a matter of science policy, the panel's work should orient the future allocation of research and evaluation resources toward the development and refinement of promising strategies for reducing violence and its consequences.
Early on, the panel recognized that the extraordinary breadth of its mandate demanded the mobilization of expertise beyond that of its own members and staff. Therefore, in addition to preparing a number of internal review memoranda, it commissioned a number of reviews and analyses by experts in certain specialized topics. Although the commissioned papers reflect the views of their authors and not necessarily those of the panel, all were valuable resources for the panel. From the entire set, the panel selected 15 for publication in supplementary volumes because it found them particularly useful. The panel is grateful to all the authors and to the discussants who prepared comments for the panel's Symposium on Understanding and Preventing Violence.
This volume contains five of the panel's commissioned reviews and analyses concerning the consequences of violence and strategies for controlling them. Mark Warr reviewed the research literature on public perceptions and reactions to violence. Mark Cohen, Ted Miller, and Shelli Rossman developed estimates of the costs of violence. Panel member Mark Moore, collaborating with Deborah Prothrow-Stith, Bernard Guyer, and Howard Spivak, explored the commonalities and complementarities of criminal justice and public health responses to violence. Jan Chaiken, Marcia Chaiken, and William Rhodes reviewed the results of efforts to reduce violence through the prediction and classification of violent offenders. Panel member Jacqueline Cohen and José Canela-Cacho analyzed the relationships between trends in violence and in prison populations during a period of extraordinary increase in the use of incarceration. The panel members believe that, like themselves, others will find these papers to be valuable sources of knowledge and insights.
