BACKGROUND Restless legs syndrome (RLS) is a common disorder in hemodialysis patients that leads to insomnia and impaired quality of life. Because high oxidative stress has been implicated in the pathogenesis of RLS, we sought to evaluate the efficacy of vitamins C and E and their combination in reducing the severity of RLS symptoms in hemodialysis patients in this randomized, double-blind, pla...
there are two major theories of measurement in psychometrics: classical test theory (ctt) and item-response theory (irt). despite its widespread and long use, ctt has a number of shortcomings, which make it problematic to be used for practical and theoretical purposes. irt tries to solve these shortcomings, and provide better and more dependable answers. one of the applications of irt is the as...
PURPOSE The objective of this study is to describe the face and discriminant validity of an exercise vital sign (EVS) for use in an outpatient electronic medical record. METHODS Eligible patients were 1,793,385 adults 18 yr and older who were members of a large health care system in Southern California. To determine face validity, median total self-reported minutes per week of exercise as mea...
View-oriented group communication systems (GCSs) are powerful tools for building distributed applications. Over the past fifteen years, group communication researchers developed a multitude of group communication semantics and implementations. Today, researchers commonly design their group communication algorithms on top of simple existing services such as a network membership service or a reli...
In this study, production, reproduction, management and economic parameters resulted from recording of 4 flocks with 1155 head of breeding ewes during annual cycle of production (August 2011 to August 2012) in extensive rearing system were used to determine the breeding objective and relative economic values for Dalagh sheep. To calculate the economic values for traits, the level of each trait ...

U.S. welfare reforms will add one to two million persons to the labor force from 19932005. Because this increase in labor supply is only about one percent of the U.S. labor force, it is unlikely that welfare reform will have sizable effects on overall U.S. wages or unemployment. However, a variety of economic models suggest that welfare reform will significantly reduce the real earnings of some...
Consider non-atomic vector measure games; i.e., games u of the form u = f o(pI.. . ,p.), where (pIr.. .,p.) is a vector of non-atomic non-negative measures and f is a real-valued function defined on the range of (pi,. . .,pi.). Games of this form arise, for example, from production models and from finite-type markets. We show that the value of such a game need not be a linear combination of the...
