Enterprise Rent-A-Car, 2006; R. v. N. S., 2010; The Queen v. D(R), 2013). In two studies, we used conventional research methods and safeguards ...

engine and airframe manufacturers for decades have cited the direct relationship between engine wear and high exhaust gas temperature (EGT) in recommending that operators use less than maximum takeoff thrust whenever possible. While the cost benefits of reduced-thrust takeoffs are thoroughly documented, the safety benefits are not as well understood. Thus, there is a common perception that usin...

minimum level. Sometimes more really is more, and less really is less. But often, less is more. If all this piece does is open up the question of whether less is more —if all it does is remind the reader that this is a question, and that our answers to it have important repercussions— then it will have served its purpose. Many ethicists in the ancient tradition argued that human lives could be ...

The study by St John Sutton et al 1 in this issue of Circulation provides additional information on the importance of the myocardial substrate for the genesis of cardiac arrhythmias, in this instance, ventricular arrhythmias in the postinfarction remodeled human left ventricle (LV). The authors demonstrate significant relationships between ventricular arrhythmias and LV size, mass, and function...
