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)
I present a proof of Wielandt's theorem by using combinatorial properties of directed graph.

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)
