Book excerpt: Violence on both large and small scales has a tremendous impact on society. The causes and impacts of violence have been under study for decades; however, in the modern era, it is important to remain knowledgeable of the current research on violence. As tragic events flood news headlines around the world, it is essential to evaluate violence, its causes, and its impact on society in order to mitigate and prevent violence globally. The Research Anthology on Modern Violence and Its Impact on Society discusses the causes, ideologies, and perceptions of modern violence and examines its impact on society. It presents emerging research on modern violence in multiple dimensions from interpersonal to mass violence. Covering topics such as gun violence, radicalization, and victim-offender overlap, this major reference work is an essential resource for sociologists, politicians, government officials, law enforcement, community leaders, educators and administrators of both K-12 and higher education, students of higher education, psychologists, criminologists, victimologists, researchers, and academicians.
