This volume contains commissioned reviews of research on biological influences on violent or aggressive behavior. The areas reviewed include genetic contributions to the probability of violent and related behaviors; brain structure and functioning as implicated in aggressive behavior; the roles of hormonal and neurological interactions in violent behavior; the neurochemistry of violence and aggression and its implications for the management of those behaviors; and dietary influences on violent behavior.

Annotation. Violence: directly or indirectly, we are its victims every day. For some people, that means locking doors and windows and turning on porch lights at night; for others, escape is more difficult. In their streets, neighborhoods, and even their homes, violence is a constant threat. The result: a diminished quality of life lived in fear. Violence is everywhere. If we escape its touch ourselves, we are continually bombarded with violent acts and their consequences in the guise of entertainment - in books, movies, and television - or in the daily news. Yet the news media cover only the most sensational crimes, the tip of the massive iceberg of violent crime in America. This coverage, which in some cities includes record-setting garish yearly body counts, tells us - and the rest of the world - that American society is exceedingly dangerous. But how violent are we? How do we measure violence in America, and how many violent crimes, in families and otherwise, go unreported? Are we becoming more violent? What can we do to find the answers to these and countless other questions? Violence has been the subject of a considerable amount of research, but often in unconnected areas or in response to specific violent events, such as assassinations or riots. In Understanding and Preventing Violence, a panel of experts assimilate the diverse research on the patterns and characteristics of violent behavior in the United States, including behaviors that have only recently been recognized as crimes - such as incest and spousal and elder abuse - and search for explanations and ways of altering these patterns and trends. The book describes what we know about certain types of violence, details insights into riskfactors for violence in individuals and situations, and recommends new research efforts with short- and long-term payoffs. Recognizing that our understanding of the causes of violence is limited and that there is a shortage.

By conservative estimates, more than 16,000 violent crimes are committed or attempted every day in the United States. Violence involves many factors and spurs many viewpoints, and this diversity impedes our efforts to make the nation safer. Now a landmark volume from the National Research Council presents the first comprehensive, readable synthesis of America's experience of violence-offering a fresh, interdisciplinary approach to understanding and preventing interpersonal violence and its consequences. Understanding and Preventing Violence provides the most complete, up-to-date responses available to these fundamental questions: How much violence occurs in America? How do different processes-biological, psychosocial, situational, and social-interact to determine violence levels? What preventive strategies are suggested by our current knowledge of violence? What are the most critical research needs? Understanding and Preventing Violence explores the complexity of violent behavior in our society and puts forth a new framework for analyzing risk factors for violent events. From this framework the authors identify a number of "triggering" events, situational elements, and predisposing factors to violence-as well as many promising approaches to intervention. Leading authorities explore such diverse but related topics as crime statistics; biological influences on violent behavior; the prison population explosion; developmental and public health perspectives on violence; violence in families; and the relationship between violence and race, ethnicity, poverty, guns, alcohol, and drugs. Using four case studies, the volume reports on the role of evaluation in violence prevention policy. It also assesses current federal support for violence research and offers specific science policy recommendations. This breakthrough book will be a key resource for policymakers in criminal and juvenile justice, law enforcement authorities, criminologists, psychologists, sociologists, public health professionals, researchers, faculty, students, and anyone interested in understanding and preventing violence.

This volume examines social influences on violent events and violent behavior, particularly concentrating on how the risks of violent criminal offending and victimization are influenced by communities, social situations, and individuals; the role of spouses and intimates; the differences in violence levels between males and females; and the roles of psychoactive substances in violent events.

Violence against women is one factor in the growing wave of alarm about violence in American society. High-profile cases such as the O.J. Simpson trial call attention to the thousands of lesser-known but no less tragic situations in which women's lives are shattered by beatings or sexual assault. The search for solutions has highlighted not only what we know about violence against women but also what we do not know. How can we achieve the best understanding of this problem and its complex ramifications? What research efforts will yield the greatest benefit? What are the questions that must be answered? Understanding Violence Against Women presents a comprehensive overview of current knowledge and identifies four areas with the greatest potential return from a research investment by increasing the understanding of and responding to domestic violence and rape: What interventions are designed to do, whom they are reaching, and how to reach the many victims who do not seek help. Factors that put people at risk of violence and that precipitate violence, including characteristics of offenders. The scope of domestic violence and sexual assault in America and its conequences to individuals, families, and society, including costs. How to structure the study of violence against women to yield more useful knowledge. Despite the news coverage and talk shows, the real fundamental nature of violence against women remains unexplored and often misunderstood. Understanding Violence Against Women provides direction for increasing knowledge that can help ameliorate this national problem.

It is now widely recognised that biological psychiatry is rapidly coming into its own. For over the last three decades dramatic advances in this young discipline have been made, all of which attest to the staying power of the experimental method. Those who made this revolution in knowledge happen are a breed of investigators availing themselves of the tools of molecular biology, pharmacology, genetics, and perhaps, above all, the technology of neuroimaging. The introduction of the interdisciplinary method of approach to the study of psychopathology had made it very clear that neuroimaging, as a set of techniques, is unique in that it is gradually providing us with evidence supporting Kraepelin's original view that mental illness is closely associated with abnormal changes in the brain.Broadly speaking, there are presently two structural techniques in neuroimaging - computed tomography and magnetic resonance imaging (MRI) - and three functional techniques - single photon emission tomography (SPECT), positron emission tomography and magnetic resonance imaging (fMRI). Through PET technology, for example, we have learned that, in early brain development, the primitive areas, mostly the brain stem and thalamus, are the first to show high activity in an infant. This is followed by the development of cortical areas by year one. Between the ages of four to 10, the cortex is almost twice as active in the child as in the adult. This information alerts us to what might happen in the way of trauma in abused children, especially those under the age of three. Child abuse increases the risk of physical changes, not only in the stress systems, but also in brain development (Glaser and Weissman). In addition to the difficult problem of post-traumatic stress disorder (PTSD), we have to take into account the possibility of other types of mental illness as the consequences of child abuse. These include depression, eating disorders, and drug and alcohol problems.The combination of PET and fMRI represents a more remarkable example of the power of neuroimaging since the two have made it feasible to map accurately in vitro identifiable cortical fields, or networks. In a landmark NIH investigation of human cortical reorganization (plasticity), persuasive evidence was brought forward showing that the process of learning as a motor task involves a specific network of neurons. These neurons occur in the cortical field that is responsible for that particular task. Such findings are important partly because they provide evidence supporting the current notion that labor in the cortex is divided among ensembles of specialized neurons that cooperate in the performance of complex tasks. Cooperation, then, in this, sense implies crosstalk among ensembles and that signals are both processed and retransmitted to neighbouring ensembles. To understand the workings of these ensembles, much better spatial and temporal resolution in functional brain mapping is required. This can be achieved with an NMR instrument whose magnet is 4.1 Tesla or more.

The Encyclopedia of Violence, Peace, and Conflict, a three-volume set written by more than 200 eminent contributors from around the world, takes advantage of increasing, worldwide awareness in the public, private, commercial, and academic sectors about manifestations of violence in all segments of society. While the contributors do not use these volumes to make specific arguments, they do describe and clarify the developments in thought that have led to current theories about and positions on violence and peace. Our reviewers consistently note that while many in-depth studies of war, peace, and aggression exist, the attendant specialization keeps scholars from learning about related fields. No publication competing with the Encyclopedia of Violence, Peace, and Conflict can satisfy their need for a vast introductory work to such a diverse and socially-important field. This major work includes more than 190 multidisciplinary articles with over 1,000 cross-references and more than 2,000 bibliography entries for further reading which are arranged alphabetically for easy access. More than 190 multidisciplinary articles with over 1,000 cross-references Article outline and glossary of key terms begin each article Entries arranged alphabetically for easy access Three-volume set with subject index of over 750 entries Articles written by more than 200 eminent contributors from around the world
