A fraud survey found that 75 percent of the 459 responding organizations experienced some form of fraud during the prior 12 month period [1]. The Association of Certified Fraud Examiners (ACFE) estimates 6 percent of revenues are lost due to theft by employees and that small businesses suffer disproportionate losses because of limited resources devoted to fraud detection [2]. Most employee thef...

Abstract. A survey of the North Celestial Pole region using the RATAN-600 radio telescope at five frequencies in the range 2.3 to 21.7 GHz is described. Sources were chosen from the NVSS catalogue. The flux densities of 171 sources in the Declination range +75◦ to +88◦ are presented; typical flux density errors are 5-10 percent including calibration errors. About 20 percent of the sources have ...

High spatial mode matching efficiencies are experimentally demonstrated when open-loop frequency-stabilized GaAlAs semiconductor lasers are heterodyned on silicon p-i-n detectors. Repeatable values of 75 percent are obtained using two independent lasers. The mode matching efficiency increases to 90 percent when a single modulated laser is self-heterodyned using an unequal path length MachZehnde...

This article investigates how a …rm’s …nancial strength a¤ects its dynamic decision to invest in R&D. We estimate a dynamic model of R&D choice using data for German …rms in high-tech manufacturing industries. The model incorporates a measure of the …rm’s …nancial strength, derived from its credit rating, which is shown to lead to substantial di¤erences in estimates of the costs and expected lo...

A new softness display system has been developed which controls the fingertip contact area dynamically according to the detected contact force, based on the human softness recognition mechanism. The relative softness cognitive rate of four levels softness using the developed system was 98 percent while ten volunteers touched the device actively. The absolute softness cognitive rate, the rate of...

Health spending in the United States is greater than the gross domestic product of most nations, and the costs for cardiovascular disease (CVD) and stroke care alone total $193.1 billion. CVD accounts for approximately one out of every three deaths in the U.S. and contributes to the shorter life expectancy of Americans. Thirtyfive percent of CVD related deaths occur before the age of 75 years, ...

Poor children in the United States start school at a disadvantage in terms of their early skills, behaviors, and health. Fewer than half (48 percent) of poor children are ready for school at age five, compared to 75 percent of children from families with moderate and high income, a 27 percentage point gap. This paper examines the reasons why poor children are less ready for school and evaluates...

www.aafp.org/afp AMERICAN FAMILY PHYSICIAN 315 tially estimated an incidence of 75 per 100,000 persons per year, but subsequent prospective studies give a range of 12.6 to 18 per 100,000 persons annually. Controversy still exists about the correct incidence because of differing criteria used to define ARDS. The prevalence of ARDS is reported to be between 15 and 18 percent of all ventilated pat...

I magine a society with perfect economic equality. Perhaps out of sheer coincidence, the supply and demand for different types of labor happen to produce an equilibrium in which everyone earns exactly the same income. As a result, no one worries about the gap between the rich and poor, and no one debates to what extent public policy should make income redistribution a priority. Because people e...

That tired Ten-Percent claim pops up all the time. Last year, national magazine ads for U.S. Satellite Broadcasting showed a drawing of a brain. Under it was the caption, "You only use 11 percent of its potential." Well, they're a little closer than the ten-percent figure, but still off by about 89 percent. In July 1998, ABC television ran promotional spots for "The Secret Lives of Men," one of...
