A widely publicized but unpublished study of the relationship between gun shows and gun violence is being cited in debates about the regulation of gun shows and gun commerce. We believe the study is fatally flawed. A working paper entitled "The Effect of Gun Shows on Gun-Related Deaths: Evidence from California and Texas" outlined this study, which found no association between gun shows and gun...
In order to develop the photo cathode gun for the Compact ERL (cERL), which is a test accelerator to establish accelerator technologies for GeV-class synchrotron light source based on ERL (Energy Recovery Linac), Gun Test Facility is constructing in KEK, AR south experimental hall. The Gun Test Facility consists of a 500 kV gun construction area, a laser system area and a gun test beamline with...
Children and firearms in the home: a Southwestern Ohio Ambulatory Research Network (SOAR-Net) study.
BACKGROUND To ascertain the prevalence of gun ownership, gun safety education, and parental attitudes on gun counseling in a Midwestern sample. METHODS Parents seeking care at participating practices in the Southwestern Ohio Ambulatory Research Network were recruited to complete a survey about gun ownership, gun safety education, and gun counseling attitudes. Attitudes and beliefs were compar...
T horrific loss of life at Sandy Hook Elementary School in Newtown, Connecticut, in December 2012 has prompted a national conversation about guns and mental illness in the United States. This tragedy occurred less than 6 months after 70 people were shot in a movie theater in Colorado and after highly publicized mass shootings in Arizona and at Virginia Tech. These four events share two common c...
BACKGROUND National surveillance systems have differentiated long guns into rifles and shotguns but fail to do so for handgun type. We sought to determine whether specific gun type data could be collected and whether knowledge of specific gun types (rifle, shotgun, pistol, revolver) could be used to distinguish gun homicide victims with respect to important injury parameters such as number of w...
OBJECTIVE To determine gun storage practices in gun-owning households with children. DESIGN National random digit-dial telephone survey of 2521 households conducted in March 1999 through July 1999. This study uses a subsample of 434 households with children <18 years old in which a respondent reported either: 1) personally owning a gun, or 2) living in a gun-owning household but not owning a ...

Gun violence is a leading cause of premature deaths in the United States. Evidence has linked higher levels of firearm ownership to an increased risk for violent crimes perpetrated with a firearm. Given that connection, the goal of this study is to use mathematical modeling techniques to better understand how different social conditions may impact gun-ownership rate. To accomplish that goal, we...
OBJECTIVE Racism is related to policies preferences and behaviors that adversely affect blacks and appear related to a fear of blacks (e.g., increased policing, death penalty). This study examined whether racism is also related to gun ownership and opposition to gun controls in US whites. METHOD The most recent data from the American National Election Study, a large representative US sample, ...
This paper provides new estimates of the effect of household gun prevalence on homicide rates, and infers the marginal external cost of handgun ownership. The estimates utilize a superior proxy for gun prevalence, the percentage of suicides committed with a gun, which we validate. Using countyand state-level panels for 20 years, we estimate the elasticity of homicide with respect to gun prevale...
