OBJECTIVES (1) Determine the frequency of gun ownership, acquisition, and transfer; (2) assess gun storage practices; and (3) compare the views of firearm owning and non-owning adults regarding the protective value of keeping a gun in the home. SETTING AND METHODS Over three different time periods (1995, 1996, and 1999) stratified, random digit telephone surveys were conducted in a five count...

OBJECTIVE Relatively little is known about the behavior of adolescents around firearms. The present investigation was undertaken to estimate the proportion of community-residing adolescents who report that they have ever handled a gun without adult knowledge or supervision. METHODS A random digit dial interview was conducted with 5801 California adolescents as part of the California Health In...

Unlike gun control, enhanced prison penalties for gun crimes enjoy widespread support from all sides of the U.S. gun policy debate. Prison sentence enhancements have the potential to reduce gun violence by incapacitating individuals who have been convicted of gun crimes and deterring such crimes in the future. Moreover, such a policy does not affect the ability of law-abiding adults to keep gun...

The 2011 attempted assassination of a US representative renewed the national gun control debate. Gun advocates claim mass-casualty events are mitigated and deterred with three policies: (a) permissive gun laws, (b) widespread gun ownership, (c) and encouragement of armed civilians who can intercept shooters. They cite Switzerland and Israel as exemplars. We evaluate these claims with analysis o...

One in three U.S. households contains at least one firearm. Gun owners cite two main reasons for having a gun: hunting and self-protection. A majority of handgun owners believe that they are protecting their homes and families against violent assaults. But in a country where the majority of homicides and suicides involve a gun, it is reasonable to question whether access to a gun increases or d...

The Staggers Rail Act of 1980 is widely perceived to have deregulated the U.S. freight rail industry. Yet substantial rail traffic remains potentially subject to regulatory rate intervention, and in the Post-Staggers era regulators have developed a detailed and expanding regulatory framework for rail shipments. This regulatory framework embodies elements of traditional public utility regulation...

This paper discusses the design issues for an high resolution rail-to-rail analog-to-digital converter. The circuit proposed uses conventional digital technology (without precise capacitors) and allows 12 bits of resolution to be achieved using 2.4 V bias and 2.4 V input dynamic range. The proposed architecture is based on the successive algorithm technique and uses a rail-to-rail autozeroed co...

The floating-gate transistor can be used to design analog circuits, such as current mirrors [1], current scaler[2] and current multiplier [3, 4] and divider [4]. The multiple input floating-gate transistor can be used to design ultra lowvoltage “pseudo differential” pairs [1], hence ULV rail-to-rail amplifiers and analog multipliers are feasible using the floating-gate technique. In this paper ...

Abstract—A fuel injection system to drive a common rail injector was developed using an 8-bit microprocessor. Common rail pressure control and injector driving systems are both essential for injecting fuel at a controlled pressure. With various duty ratios of the square wave generated from the CCP (capture compare PWM) pin of a microprocessor to the common rail pressure controller, the common r...

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...
