The present study was done to estimate rise in skin temperature during a pain reaction time (pain RT) as a means of investigating why a pricking pain threshold, produced by thermal stimulation using time method, often increases during repeated measurements. The pain RT, or the time-delay between occurrence of pain sensation and a subsequent motor response, was measured by making EMG recording on a forearm. The radiant heat stimuli were three, 200, 300, and 350 mcal/sec./cm2, each of which was given through a round radiation window of an algesiometer head. Analysis showed that the pain RTs would be too short to explain higher pain thresholds often found using the time method.

The purpose of this study was to examine attitudinal factors associated with increased research productivity of individual clinical faculty in 66 United States and Canadian schools of dentistry. Thirteen variables, evaluating the subjects' perceptions of their research background, work environment, attitude and outcome effects from publishing, and the use of colleagues in conducting research, were evaluated. The 833 respondents represented a response rate of 64.9% (833/1200) from a 50% stratified random sample of faculty who (1) had full-time appointments and held at least the D. ⋯ Respondents reported a mean of 10.3 yr. (range = 1 to 45, SD = 7.3) in full-time dental education (career age) and a mean of 10.1 career publications (range = 0 to 110, SD = 13.8). Analysis of variance for mean number of career publications, by increasing agreement in response to each attitudinal variable, yielded a significant positive association for each of the 13 attitudinal variables. Implications of the findings were discussed with respect to strategies for improving research productivity of individual faculty.
