Most people are aware that regular alcohol drinkers can become tolerant to the effects of alcohol. Tolerance can lessen the outward manifestations of intoxication, and this poses challenges for the drinker and other observers, including law enforcement officers. On the basis of a National Institutes of Health-funded longitudinal study examining a cohort of convicted alcohol-impaired drivers, th...

Although not deliberately planned and organized, the campaign, fueled by press reports, was perceived by many observes to be a national organized deterrent effort. To test the hypothesis that the crusade reduced drunken ...

(d) Suppose list1 contains N1 elements and list2 contains N2 elements. The first while loop is executed O(N1) times. The body of this loop takes O(N1) since GetNextItem takes O(1) and InsertItem takes O(N1). So, the complexity of the first loop is O(N1N1). The second while loop is executed O(N2) times. The body of that loop takes O(N1+N2) time since GetNextItem takes O(1), RetrieveItem takes O(...

Adolescence is often described as a period of heightened risk-taking. Adolescents are notorious for impulsivity, emotional volatility, and risky behaviors such as drinking and driving under the influence of alcohol. By contrast, we found that risk-taking declines linearly from childhood to adulthood when individuals make choices over monetary gambles. Further, with age we found increases in the...
