This paper draws on theories of gendered organizations to examine discrimination against people with disabilities in the workplace. A sample of 200 cases which document disability discrimination lawsuits was drawn from the Westlaw legal database. Each case was coded for gender, job, disability and discrimination type and analyzed using multinomial logistic models. Of th....

Inhalants are a critical, under-studied substance used by young adolescents in the United States (U.S.). Despite the serious negative consequences that can accompany use (most notably neuropsychological damage) the topic of inhalants has been neglected by clinicians and prevention scientists, particularly in comparison to other drugs. The present research focused on the....

Sire evaluations from first, all, and later lactations for Predicted Difference milk, fat, and dollars on 226 sires were used to predict deviated relative net income. Eleven different relative net incomes were calculated on 176,902 individual cows. Low, medium and high values were used for lifetime product value and feed price. Lifetime product value was actual milk and....

We consider the problem of optimal evasion when the pursuer is known to employ fixed gain proportional navigation . The performance index is a measure of closest approach. The analysis is done for planar motions at constant speed. The kinematics are first linearized around a nominal collision course. The dynamics of the opponents are modeled by first order systems an....

Thirty-one Dorset (D), 24 Finnish Landrace (F), 35 Barbados Blackbelly x Dorset (BD), 10 Dorset x Finn (F), 24 Finn x Dorset (FD) and 35 grade Rambouillet (R) ewes were exposed to rams in various seasons. Ewes were born in 1979 or 1980; no R ewes were born in 1980. Ewes were bred in April, 1980 (APR80); November, 1980 (NOV80); August, 1981 (AUG81); May, 1982 (MAY82); an....

The effectiveness of selected computer-generated graphics display variables was examined in a mixed-factors factorial experiment using thirty-two subjects. All subjects performed four different graph reading tasks consisting of point-reading, point-comparison, trendreading, and trend-comparison. In each task, line, point, bar, and three-dimensional bar graphs were inves....

A highway culvert entrance is always built with two vertical wing walls and a flat apron between them. The Virginia V-notch is placed mid-way of the wing walls. If the water measuring section is selected somewhere within the wing walls, its area will be linearly proportional to the measured head with a proportional constant equaling the width of the section. If the dist....

Equations were derived to calculate the reflection points of acoustic rays emanating from a source to a receiver. Reflection points for up to three reflections could be determined if the location of the source, receiver and all reflecting surfaces were known. Assuming a point source, the distances along the calculated ray paths were used along with the power level of th....
