The most common medical cause of excessive daytime sleepiness (EDS) is obstructive sleep apnea (OSA). Specifically, among an estimated 14 million US commercial drivers, 17-28% or 2.4 to 3.9 million are expected to have OSA. Based on existing epidemiologic evidence, most of these drivers are undiagnosed and not adequately treated. Untreated OSA increases the risk of vehicular crashes as document...

Firm-risk and managerial risk-taking though distinct are used interchangeably in empirical literature. Here, we identify these two distinctly by examining different proxies for them. We use income stream uncertainty accounting beta to proxy firm-risk, market risk capital intensity ratio represent risk-taking. Once defined, our objective is find the antecedents of both using most advanced struct...

This article serves as an overview of both clinical and research issues relevant to enhancing the safety of older drivers. Even though the vast majority of older drivers are safe on the road, physicians and other health care providers need tools and mechanisms for identifying those older drivers who are a safety risk because of cognitive, sensory, and/or other medical impairments. Research in t...

One of the prominent issues in contemporary research on young drivers deals with the mechanisms underlying parents' influences on their offspring's driving behavior. The present study combines two sets of data: the first gathered from in-vehicle data recorders tracking the driving of parents and their teenage sons, and the second derived from self-report questionnaires completed by the young dr...

background the most accidents can be directly attributed to human factors. hence, more traffic crashes result from driver malfunctioning which from among them, the driver behavior is a proximal factor in the road traffic injuries causation chain. objectives this study aims to investigate relationship between aberrant driving behaviors questionnaire (dbq factors) and self-report crashes involvem...

We consider the sabotage game as presented by van Benthem. In this game one player moves along the edges of a finite multigraph and the other player takes out a link after each step. One can consider usual algorithmic tasks like reachability, Hamilton path, or complete search as winning conditions for this game. As the game definitely ends after at most the number of edges steps, it is easy to ...

Background: The prevalence of hypertension (HTN) among Iranian taxi drivers has not been well defined. This study aimed to determine the prevalence of HTN and to identify factors influencing its prevalence among Iranian taxi drivers in 2018. Materials and Methods: This cross-sectional study was conducted on a total sample of 321 taxi drivers in Kermanshah province in 2018. The participants wer...

BACKGROUND The rapidly increasing number of older drivers is accentuating the challenges in concurrently identifying older drivers posing an unacceptable risk if they continue to drive, while not discriminating against those capable of safely driving. Attendees of an invitational meeting about the assessment of older drivers were asked to participate in a modified Delphi process designed to dev...
