Probable solar flare doses encountered on an interplanetary mission as calculated by the MCFLARE code

The computer program, MCFLARE, uses Monte Carlo methods to simulate solar flare occurrences during an interplanetary space voyage. The total biological dose inside a shielded crew compartment due to the flares encountered during the voyage is determined. The computer program evaluates the doses obtained on a large number of trips having identical trajectories. From these results, a dose D sub p having a probability p of not being exceeded during the voyage can be determined as a function of p for any shield material configuration. To illustrate the use of the code, a trip to Mars and return is calculated, and estimated doses behind several thicknesses of aluminum shield and water shield are presented

Type IIB orientifolds with discrete torsion

We consider compact four-dimensional ${\bf Z_N}\times {\bf Z_M}$ type IIB orientifolds, for certain values of $N$ and $M$. We allow the additional feature of discrete torsion and discuss the modification of the consistency conditions arising from tadpole cancellation. We point out the differences between the cases with and without discrete torsion.Comment: 4 pages LaTeX. Write-up of talk at DPF2000, Columbus, OH, August 10, 2000. References adde

Student Perceptions and Grade Comparisons after Exposure to Instructor-Made Skills Videos in a Kinesiology Course

The purpose of this mixed method, descriptive case study was to determine whether the use of pre-recorded instructor-made videos (PRIMVs) in a kinesiology course, along with curricular design changes, facilitated increased conceptual and practical student learning. The study examined three student cohorts in one occupational therapy program. Two of the student cohorts had unrestricted access to the PRIMVs designed to support student learning of bone and muscle palpation and joint actions. Students from the two cohorts completed a survey about their experience of having access to the videos. Exam data from the student cohorts who had access to the videos was compared to exam data from an earlier cohort who had not been exposed to the videos. While no significant differences in the lab exam grades were noted, quantitative and qualitative data collected from the surveys revealed that students perceived that their overall course grade was higher and they were better prepared for clinical fieldwork as a result of having access to the videos. This study adds to the growing body of evidence that supports video technology as a supplemental learning tool in occupational therapy education
