Even a one-hour extension in bar closing hours can lead to a 16 percent increase in violent incidents, Norwegian researchers reported November 29 in the journal *Addiction. * The study was based on data from 18 Norwegian cities that expanded or restricted their closing hours by up to two hours during the decade 2000-2010.

Since violence is endemic in modern Western society, mental health professionals need to be skilled in assessing and managing violence in patients. A book from American Psychiatric Publishing, the *[Textbook of Violence Assessment and Management](http://www.appi.org/SearchCenter/Pages/SearchDetail.aspx?ItemID=62314)* can help professionals deal with violence ideation and behavior in their patients.
