Examples for which evidence of effectiveness is emerging includes: screening tools to identify victims of intimate partner violence and refer them to appropriate services; psychosocial interventions—such as trauma-focused cognitive behavioural therapy—to reduce mental health problems associated with violence, including post-traumatic stress disorder; and protection orders, which prohibit a perpetrator from contacting the victim, to reduce repeat victimization among victims of intimate partner violence. Collective violence
Not surprisingly, scientific evidence about the effectiveness of interventions to prevent collective violence is lacking. However, policies that facilitate reductions in poverty, that make decision-making more accountable, that reduce inequalities between groups, as well as policies that reduce access to biological, chemical, nuclear and other weapons have been recommended. When planning responses to violent conflicts, recommended approaches include assessing at an early stage who is most vulnerable and what their needs are, co-ordination of activities between various players and working towards global, national and local capabilities so as to deliver effective health services during the various stages of an emergency. Criminal justice
One of the main functions of law is to regulate violence. Sociologist Max Weber stated that the state claims the monopoly of the legitimate use of force practised within the confines of a specific territory. Law enforcement is the main means of regulating nonmilitary violence in society. Governments regulate the use of violence through legal systems governing individuals and political authorities, including the police and military. Civil societies authorize some amount of violence, exercised through the police power, to maintain the status quo and enforce laws.
When "symbols of Cambodian society were equally disrupted, social institutions of every kind…were purged or torn down", cultural violence (defined as when "any aspect of culture such as language, religion, ideology, art, or cosmology is used to legitimize direct or structural violence") is added to the structural violence of forced movement and to the direct violence, such as murder, at the Killing Fields. Vietnam eventually intervened and the genocide officially ended. However, ten million landmines left by opposing guerillas in the 1970s continue to create a violent landscape in Cambodia. Human geography, though coming late to the theorizing table, has tackled violence through many lenses, including anarchist geography, feminist geography, Marxist geography, political geography, and critical geography. However, Adriana Cavarero notes that, "as violence spreads and assumes unheard-of forms, it becomes difficult to name in contemporary language". Cavarero proposes that, in facing such a truth, it is prudent to reconsider violence as "horrorism"; that is, "as though ideally all the…victims, instead of their killers, ought to determine the name". With geography often adding the forgotten spatial aspect to theories of social science, rather than creating them solely within the discipline, it seems that the self-reflexive contemporary geography of today may have an extremely important place in this current (re)imaging of violence, exemplified by Cavarero. Epidemiology
As of 2010, all forms of violence resulted in about 1.34 million deaths up from about 1 million in 1990. Suicide accounts for about 883,000, interpersonal violence for 456,000 and collective violence for 18,000.
