Applications must scale well to make efficient use of even medium-scale parallel systems. Because scaling problems are often difficult to diagnose, there is a critical need for scalable tools that guide scientists to the root causes of performance bottlenecks. Although tracing is a powerful performance-analysis technique, tools that employ it can quickly(More)
Twenty-four male Sprague-Dawley rats were tested for wheelrunning in conjunction with chronic (continuous) or subchronic (alternate day) oral caffeine administration. As expected, chronic administration led to complete tolerance to caffeine's locomotor stimulant effect, while subchronic administration produced sensitization. Results confirm earlier reports(More)
Humility is a psychological construct that has not received much empirical attention until recently. This new emphasis on positive psychology and humility has been both conceptual and empirical. The present study had two objectives: to review the literature briefly to verify the importance of humility and its positive perception by others, and to begin to(More)
One group of normal elderly adults and two groups of cognitively impaired elderly adults were compared on an implicit and an explicit memory task. Degree of impairment affected explicit memory; the mildly and moderately impaired elderly adults demonstrated significantly reduced recognition performance. Degree of impairment also affected implicit memory(More)
Undergraduate students (N=691) were given the 1992 Caffeine Consumption Questionnaire of Landrum and provided information on age, sex, and year in school. A subset (n = 168) of those completing the questionnaire were also given the Morningness-Eveningness Questionnaire of Horne and Ostberg. Analysis indicated that the average intake of caffeine was roughly(More)
72 students solved two problems using a source problem designed to inhibit performance on the target problem relative to baseline performance when the target problem was solved alone. Both source and target problems shared surface similarity but were structurally dissimilar. Negative transfer was found for three different source and target combinations. The(More)
Pictorial stimuli were used to investigate implicit- and explicit-memory phenomena in 3 experiments. The general procedure involved the presentation of a series of pictures during a study phase, followed by an implicit-memory test and an explicit-memory test. In the implicit-memory test, participants were presented with picture fragments and were instructed(More)
Male Sprague-Dawley rats were tested for wheelrunning following repeated injections of caffeine or distilled water after varying amounts of experience with caffeine and wheelrunning. Rats experienced with caffeine in combination with wheelrunning ran significantly more than rats experienced only with caffeine or wheelrunning alone. Results suggest that(More)
Using data from 8 academic departments and 361 courses taught during a semester, I examined differences between fulltime and parttime faculty in the areas of general demographic variables, student evaluation of teaching outcomes, and the distribution of grades earned. I expected fulltime faculty to exhibit higher teaching evaluations and less lenient grade(More)
