The profitability of workers’ compensation insurance has improved dramatically over the past few years. At the same time the use of large insurance deductibles has been on the rise across the country. This is one of the first studies to empirically test whether deductibles are associated with changes in employer workers’ compensation costs, and hence, may be responsible for at least some of the...

this study addresses executive compensation from shareholders perspective by empirically examining the effects of chief executive officer (ceo) compensation on firm performance subsequent to the year of compensation. three factors of ceo compensation are examined, size, total annual compensation; form percentage of total compensation comprised of cash, cash bonuses and stock; and sensitivity. t...

EVERAL studies have shown that certain mutants revert more frequently when homozygous than when hemizygous, a phenomenon termed “selfing” by DEMEREC (1 962). Reversion of serial tandem duplications by asymmetric pairing and crossing over has been demonstrated for several mutants following the classical study of Bar by STURTEVANT (1925). For Salmonella typhimurium, DEMEREC (1 962, 1963) has repo...

Biological rhythms are regulated by homeostatic mechanisms that assure that physiological clocks function reliably independent of temperature changes in the environment. Temperature compensation, the independence of the oscillatory period on temperature, is known to play a central role in many biological rhythms, but it is rather rare in chemical oscillators. We study the influence of temperatu...

We present an interferometric technique based on a differential interferometry setup for measurement under atmospheric conditions. The key limiting factor in any interferometric dimensional measurement are fluctuations of the refractive index of air representing a dominating source of uncertainty when evaluated indirectly from the physical parameters of the atmosphere. Our proposal is based on ...
