There is no software engineering crisis. In order to determine what is meant by the phrase “software engineering crisis,” it is informative to define both the term crisis and the term software engineering. We define crisis to mean a “crucial or decisive point or situation; a turning point.” [1] While not part of the definition, the usual connotation of a crisis further implies an impending disa...

Answering a question of Per Lindstrom, we show that there is no \plus-capping" degree, i.e. that for any incomplete r.e. degree w, there is an incomplete r.e. degree a > w such that there is no r.e. degree v > w with a \ v = w. 1. The Theorem. In [2], Feferman de nes relative interpretability for extensions of Peano arithmetic. The induced structure D T of degrees of interpretability turns out...

In 2005, Dr David Brailer, our first National Coordinator for Health Information Technology, had a vision of widespread adoption of electronic health records connected through networks run by regional health-information organizations. An advisory panel recommended at that time that proactive fraud management functions be embedded in this emerging information infrastructure. This has not occurre...

Cigarette smoking is the leading preventable cause of death in the world. Nicotine is a highly addictive substance. Nicotine dependence is a major barrier to successful smoking cessation. Smoking is a risk factor for 30 diseases with a high rate of morbidity and mortality. There is no safe level of smoking. Help and support to smoking cessation should be an integral part of treatment, particula...

We show that if NP , co−RP then the existence of efficient indistinguishability obfuscation (iO) implies the existence of one-way functions. Thus, if we live in “Pessiland”, where NP problems are hard on the average but one-way functions do not exist, or even in “Heuristica”, where NP problems are hard in the worst case but easy on average, then iO is impossible. Our result makes it redundant t...
