Test-retest reliability of the Test of Variables of Attention (T.O.V.A.) was investigated in two studies using two different time intervals: 90 min and 1 week (2 days). To investigate the 90-min reliability, 31 school-age children (M = 10 years, SD = 2.66) were administered the T.O.V.A. then read ministered the test 90 min afterward. Significant reliability… (More)
A number of recent research efforts have been based on the hypothesis that encapsulation techniques, formal specification, and verification lead to significant improvements in program quality. As we gain experience with the language facilities produced by this research, we should attempt to validate that hypothesis. This paper poses this validation as the… (More)
BACKGROUND Severity of illness is an important consideration in making the decision to transfuse as it is the sicker patient that often needs a red cell transfusion.

Objectives: To determine the effects of type of artificial-insemination catheter on litter size and farrowing rate and to evaluate the economic differences between the two catheters on the basis of the differences observed in reproductive performance. Materials and methods: Three hundred eighty-nine sows were allotted into two experimental groups by parity,… (More)
