    Notes: This exploratory study investigated the impact of learning styles on human-computer interaction. Seventy learners who were enrolled in a large urban post-secondary institution participated in the study. The Gregorc Style Delineator™ was used to obtain subjects' dominant learning style scores. Results indicated that patterns of learning indices did not differ significantly based on subjects' dominant learning style. Five of the six measures indicating human-computer interaction behavior were not significant at the p 〈 0.05 level. However, learning styles significantly affected learning outcomes, as indicated by a significant main effect, as well as an interaction effect between dominant learning style and achievement scores. It would appear that Abstract Random learners may be at-risk for doing poorly with certain forms of computer-aided instruction. Based on the review of literature and results found in this study, it was concluded that computer-aided instruction may not be the most appropriate method of learning for all students.

    Description: Based on experimental drug concentration profiles in healthy as well as tape-stripped ex vivo human skin, we model the penetration of the antiinflammatory drug dexamethasone into the skin layers by the one-dimensional generalized diffusion equation. We estimate the position-dependent free-energy and diffusivity profiles by solving the conjugated minimization problem, in which the only inputs are concentration profiles of dexamethasone in skin at three consecutive penetration times. The resulting free-energy profiles for damaged and healthy skin show only minor differences. In contrast, the drug diffusivity in the first 10 μm of the upper skin layer of damaged skin is 200-fold increased compared to healthy skin, which reflects the corrupted barrier function of tape-stripped skin. For the case of healthy skin, we examine the robustness of our method by analyzing the behavior of the extracted skin parameters when the number of input and output parameters are reduced. We also discuss techniques for the regularization of our parameter extraction method.
