A Monte Carlo Study of the Robustness and Power Associated with Selected Tests of Variance Equality when Distributions are Non-Normal and Dissimilar in Form

Description: When selecting a method for testing variance equality, a researcher should select a method which is robust to distribution non-normality and dissimilarity. The method should also possess sufficient power to ascertain departures from the equal variance hypothesis. This Monte Carlo study examined the robustness and power of five tests of variance equality under specific conditions. The tests examined included one procedure proposed by O'Brien (1978), two by O'Brien (1979), and two by Conover, Jo… more

Alzheimer's Disease and Attention: An Investigation into the Initial Stage of Information Processing

Description: This study explores the possibility that attentional deficits are an early clinical symptom of Alzheimer's disease. The three goals are to demonstrate that individuals with Alzheimer's disease are impaired on tasks of attentional processing, to compare the sensitivity of currently used measures of attention to attentional dysfunction, and to compare the behavioral response styles (errors of commission) of Alzheimer's disease subjects and non-impaired subjects. The subjects were 22 males and 46 … more

Methylglyoxal Effects on Cell Division of Scenedesmus quadricauda (Scenedesmaceae)

Description: Cell division of ggeneflesmus quadricauda (Turp.) Breb. (Scenedesmaceae) is enhanced by methylglyoxal, a general inhibitor of cell division, at threshold concentration in conjunction with treatment timing related to growth stage of batch cultures. At 0.5 mM methylglyoxal concentration, cell division was significantly enhanced in algae treated in the logarithmic phase. Specific growth rates of methylglyoxal-treated cultures were rapidly increased at the beginning of logarithmic phase. Cultures i… more
