Sensorineural hearing loss following trauma is a common finding in daily clinical practice and usually associated with a poor prognosis. Our case illustrates a patient who was involved in motor vehicle accident sustaining bilateral severe to profound sensorineural hearing loss but subsequently recovered fully after two years. Unless there is clear trauma to the cochlea or auditory nerve, a subs...

A review of the literature published on the genotoxicity of soil is presented in this report. Subheadings of the report include outlines of genotoxicity assays that have been used to examine the soil samples and methods commonly used to prepare soil samples for genotoxicity assay, and a review of the genotoxicity of soil. Soil has been grouped according to potential sources of pollution, e.g. i...

CONTEXT Implementation of graduated driver licensing programs is associated with reductions in crash rates of young drivers, but graduated driver licensing programs vary in their components. The impact of programs with different components is unknown. OBJECTIVE The purpose of this work was to determine which graduated driver licensing programs are associated with the greatest reductions in fa...

Anecdotal and circumstantial evidence suggest that the implementation of Secure Communities, a federal program that allows police officers to more easily identify illegal immigrants, has increased racial bias by police. The goal of this analysis is to empirically evaluate the effect of Secure Communities on racial bias by police using motor vehicle stop and search data from the North Carolina S...

Atmospheric aerosols have been shown to be an important input of organic carbon and nutrients to alpine watersheds and influence biogeochemical processes in these remote settings. For many remote, high elevation watersheds, direct evidence of the sources of water soluble organic aerosols and their chemical and optical characteristics is lacking. Here, we show that the concentration of water sol...

This chapter investigates current mobility trends and their implications for sustainability. It discusses factors that affect transport demands (the amount and type of travel that people would choose in a particular situation) and how demographic and economic trends affect these demands. During most of the last century, motor vehicle travel grew steadily in most developed countries. During this...
