Two waves of longitudinal data were used to examine the sequencing between violent victimization, violent behavior, and gun carrying in a high poverty sample of African American youth. Multivariate logistic regression results indicated: (1) violent victimization T1 and violent behavior T1 increased the likelihood of initiation of gun carrying T2 when examined separately (by 132% and 91% respect...

A case-control study of 149 intentionally self-inflicted gun injury cases (including completed gun suicides) and 302 population-based controls was conducted from 2003 to 2006 in a major US city. Two focal independent variables, acute alcohol consumption and alcohol outlet availability, were measured. Conditional logistic regression was adjusted for confounding variables. Gun suicide risk to ind...

IC ER SPTIVES On contentious issues such as gun control, where advocacy groups on both sides claim to have the weight of public opinion behind them, polling can help clarify what Americans really think. Three decades of polling have painted a clear picture of public opinion about gun control. These polls show that public support for the regulation of firearms is strong, deep, and widespread. La...

• Cost saving The gun turret drive on a combat vehicle presents a very complex design challenge. When the vehicle travels over rough terrain, the gun turret drive compensates for the vehicle’s motion and keeps the gun pointed precisely at its target with 99.5% accuracy. In the past, General Dynamics Land Systems (GDLS) engineers used separate simulations to evaluate different aspects of the gun...

Abstract The overload reliability of EFI-based insensitive initiation unit is the basis for improving combat effectiveness ammunition. Based on air gun experiment, evaluation method was obtained, as it’s weakest units in initiation, enhancement and adaptability were systematically studied. results show that, once peak value pulse width exceed 100,000 g 100μs, backplane acceleration chamber opti...

This comment on Thomas Marvell’s “The Impact of Banning Juvenile Gun Possession” analyzes Marvell’s empirical findings and their policy implications for gun control legislation. While Marvell’s article stresses the absence of any finding favorable to juvenile gun bans, this comment points out that the statistical results actually support the stronger finding that some of the juvenile gun bans a...

Current Process HVOF thermal spray is widely used for coating critical wear parts like landing gear, bearing races, valves and turbine components. Generally, fully or partially molten metal, composite, or ceramic droplets are propelled from a gun or torch onto the workpiece. Multiple passes are required to build up the coating, since each pass only deposits ~ 0.0002 in 0.0005 in thickness of ma...

Gun violence is related to substantial morbidity and mortality with surrounding discussions framed and shaped by the media. This study's objective was to explore national news media's reporting of gun violence around a mass shooting. National news pieces were coded according to categories of gun violence, media frames, entities held responsible, responses, and reporting of the public heath appr...
