Violence is defined by the World Health Organization as the intentional use of physical force or power, threatened or actual, against oneself, another person, or against a group or community, that either results in or has a high likelihood of resulting in injury, death, psychological harm, maldevelopment or deprivation. This definition associates intentionality with the committing of the act itself, irrespective of the outcome it produces.

Globally, violence takes the lives of more than 1.5 million people annually: just over 50% due to suicide, some 35% due to homicide, and just over 12% as a direct result of war or some other form of conflict. For each single death due to violence, there are dozens of hospitalizations, hundreds of emergency department visits, and thousands of doctors' appointments. Furthermore, violence often has life-long consequences for victims' physical and mental health and social functioning and can slow economic and social development.

Violence, however, is preventable. Evidence shows strong relationships between levels of violence and potentially modifiable factors such as concentrated poverty, income and gender inequality, the harmful use of alcohol, and the absence of safe, stable, and nurturing relationships between children and parents. Scientific research shows that strategies addressing the underlying causes of violence can be effective in preventing violence. Examples of scientifically credible strategies to prevent violence include nurse home-visiting and parenting education to prevent child maltreatment; life skills training for children ages 6–18 years; school-based programmes to address gender norms and attitudes; reducing alcohol availability and misuse through enactment and enforcement of liquor licensing laws, taxation and pricing; reducing access to guns and knives; and promoting gender equality by, for instance, supporting the economic empowerment of women.

Matthew Mackendree "Matt" Lanter (born April 1, 1983) is an American actor, former reality TV personality and model, perhaps best known for his roles in Commander in Chief, 90210, Star Wars: The Clone Wars, Disaster Movie, Sorority Row and Vampires Suck.

Lanter was born in Massillon, Stark County, Ohio, the son of Joseph "Joe" Lanter and Jana Burson. He moved to Atlanta, Georgia in 1991 at age 8. Lanter graduated from Collins Hill High School in 2001. He played baseball, football, basketball, gymnastics and golf and was a batboy for the Atlanta Braves. He attended University of Georgia, majoring in sports business, but an interest in the film and television industry created a strong desire to pursue acting instead.

In 2004, Lanter was a contestant on Bravo's reality show Manhunt: The Search for America's Most Gorgeous Male Model. He did not win the competition.

Within a few weeks of moving to Los Angeles, California, Lanter successfully auditioned for the role of Nick on the Supernatural Teen-Drama Fox series Point Pleasant. He had a major recurring role throughout the series first and only season. He has since then appeared in television shows such as Grey's Anatomy, 8 Simple Rules, Big Love and Heroes.

Violent Femmes were an American alternative rock band from Milwaukee, Wisconsin, initially active between 1980 and 1987 and again from 1988 to 2009. The band performed as a trio, including: singer, guitarist and songwriter Gordon Gano, bassist Brian Ritchie, and two drummers, Victor DeLorenzo (1980–1993 and 2002–2009) and Guy Hoffman (1993–2002).

The Violent Femmes released eight studio albums and fifteen singles during the course of their career. The band found immediate success with the release of their self-titled debut album in early 1983. Featuring many of their well-known songs, including "Blister in the Sun", "Kiss Off", "Add It Up" and "Gone Daddy Gone", Violent Femmes became the band's biggest-selling album and was eventually certified platinum by the RIAA. Violent Femmes went on to become one of the most commercially successful rock bands of the 1980s and 1990s, selling over 9 million albums by 2005. After the release of their third album The Blind Leading the Naked (1986), the band's future was uncertain and they split up in 1987, when Gano and Ritchie went solo. However, they regrouped a year later, releasing the album 3 (1989). Since then, Violent Femmes' popularity continued to grow, especially in the United States where the songs "Nightmares" and "American Music" cracked the top five on the Modern Rock Tracks chart.
