Self-efficacy is a user's confidence that he or she has the ability to use an information system. A survey gathered demographics, self-assessed computer skills, attitude and self-efficacy before installation of an integrated clinical and administrative information system. Results showed that higher levels of nursing education, home computer use, and average(More)
Sweat lactate reflects eccrine gland metabolism. However, the metabolic tendencies of eccrine glands in a hot versus thermoneutral environment are not well understood. Sixteen male volunteers completed a maximal cycling trial and two 60-min cycling trials [30 degrees C = 30 +/- 1 degrees C and 18 degrees C = 18 +/- 1 degrees C wet bulb globe temperature(More)
Intelligent Learning Environments (ILE) are constructivist systems that attempt to incorporate beneficial aspects of tutoring systems and cognitive tools. ILEs support discovery learning through reflective interaction as well as curriculum-driven learning through scaffolding and coaching. ILEs are concerned with students developing both general and domain(More)
AIM The potential influence of a hotter vs cooler environment on ratings of perceived exertion (RPE) estimations during longer duration exercise is not well-understood. This study compared overall and differentiated RPEs during cycling in 18 degrees C vs 30 degrees C wet bulb globe temperature (WBGT). METHODS Male volunteers (n=16) completed a maximal(More)
AIM Ratings of perceived exertion (RPE) have been shown similar across subjects of varying fitness when estimations are made at relative physiological criteria. Because few studies have investigated the influence of fitness during longer duration bouts, the current investigation compared overall exertion (RPE-O), leg exertion (RPE-L) and breathing/chest(More)
BACKGROUND This study examined physiological responses during 0% and 10% inclined treadmill exercise at prescribed ratings of perceived exertion (RPE) using the perceptual estimation-production paradigm. METHODS RPE's were estimated during a Bruce treadmill test to volitional exhaustion. Subjects then produced individually prescribed RPE's (associated(More)
