BACKGROUND Gun theft is an important source of guns used by criminals. Yet no empirical work has focused on the characteristics of gun owners that distinguish those who have had their guns stolen from those who have not. In this study, we examine the demographics and behavioral characteristics of gun owners who report having had a gun stolen. METHODS Data come from a nationally representative...
BACKGROUND Many scientific studies have shown that the mere presence of guns can increase aggression, an effect dubbed the "weapons effect." The current research examines a potential source of the weapons effect: guns depicted in top-selling films. METHODS Trained coders identified the presence of violence in each 5-minute film segment for one-half of the top 30 films since 1950 and the prese...
Biology and the particular gun culture of the United States come together to explain the persistent and powerful attraction of American boys to both real guns and toy guns. The 1990s saw adults begin to conflate “the gun problem” with “the boy problem,” sparking attempts (largely failed) to banish toy guns from homes and schools. Following the approach of play scholar Gregory Bateson, this arti...

The main argument of a recent book by John Lott is summarized in the title: More Guns, Less Crime [26]. There are three parts to this argument: 1. that there were more guns 2. that there was less crime 3. that more guns caused less crime Lott’s argument depends on all three parts being true. If any one of the parts is incorrect, the entire argument fails. In fact, as I will show in the next thr...
The life cycle of crime guns: a description based on guns recovered from young people in California.
STUDY OBJECTIVE We describe the life cycle of crime guns recovered from young people-the movement of those guns from manufacture to criminal use-and identify associations between the characteristics of those guns and their possessors, purchasers, sellers, and places of origin. METHODS This is a cross-sectional study of data from gun ownership tracing records compiled by the Bureau of Alcohol,...
New type of high perveance electron guns with convex cathode has been developed. Three guns described in this article are built to provide transverse electron current density distributions needed for Electron Lenses for beam-beam compensation in the Tevatron collider. The current distribution can be controlled either by the gun geometry or by voltage on a special control electrode located near ...
Rush Limburger: Well it seems pretty stupid to me. I know how you research people do this. You do a “randomized controlled trial.” You pick a kindergarten class and give half of the kids toy guns and not the other half, then see who commits more crimes. You control the “intervention” and watch for “outcomes.” Of course this cannot be done. It is unethical to withhold guns from law-abiding citiz...
On an average day in the United States, more than 100 Americans die by suicide; half of these suicides involve the use of firearms. In this ecological study, we used linear regression techniques and recently available state-level measures of suicide attempt rates to assess whether, and if so, to what extent, the well-established relationship between household firearm ownership rates and suicide...
