The one dimensional nearest neighbors asymmetric simple exclusion process in used as a microscopic approximation to the Burgers equation. We study the process with rates of jumps p > q to the right and left, respectively, and with initial product measure with densities ~ < 2 to the left and right of the origin, respectively (with shock initial conditions). We prove that a second class particle ...

Students in two Java programming classes completed an individualized tutoring system that taught a simple applet program. Before and after using the tutor, students completed questionnaires that assessed software self-efficacy and understanding of general programming principles. The questionnaires also were administered following a lecture session on the program that included having the student...

OBJECTIVE The goal of this study was to determine differences in moral judgment among students in medical school. METHODS This cross-sectional study involved students currently enrolled in undergraduate medical education. Recruited via email, 192 students took an online version of the Defining Issues Test to determine their current stage of moral judgment, as well as their percentage of postc...

The one-dimensional nearest-neighbor totally asymmetric simple exclusion process can be constructed in the same space as a lastpassage percolation model in Z. We show that the trajectory of a second class particle in the exclusion process can be linearly mapped into the competition interface between two growing clusters in the lastpassage percolation model. Using technology built up for geodesi...

Human-computer interaction is a very recent discipline at the Universidad de Costa Rica. In this paper we present the experiences of the first academic year the first courses about humancomputer interaction, an undergraduate course and a Masters course, were designed and taught. The HCI course introduction strategy consisted of two steps: 1) to initiate a dedicated undergraduate course during t...

Different people choose undergraduate degrees to study at university for different reasons. To date, there have been limited attempts to identify individual differences in motivation that drive undergraduate degree choice. We identified that people choose university degrees for four reasons: career concerns (Career), intrinsic interest in the subject (Interest), an opportunity to help others (H...
