objectives: we aimed to design, implement and evaluate the efficacy of a comprehensive course on non-clinical competencies that dentists must possess for a successful dental practice. materials and methods: in this interventional before-after study an expert panel of five academic staff members and five general practitioners derived the topics for a course on successful dental practice, and agg...

Prior to the third generation of distance education that is described as telelearning (Taylor 1995) or teleconferencing (Moore and Kearsley 1996), there were few questions about the ownership of a faculty member’s intellectual property. It was extremely rare for an institution to claim ownership of a professor’s class materials whether lecture notes, flip charts, overhead transparencies, audio ...

We show that for every n there are two simple curves on the torus intersecting at least n times without the two curves folding or spiralling with respect to each other. On the other hand, two simple curves in a punctured plane that intersect at least n times (and do not create any empty bigons) must either form a spiral of depth d or a fold of width cn/(d + 1) − 1, where c only depends on the n...

The prevalence and characteristics of mentorship among junior faculty in clinician-scientist and clinician-educator tracks were evaluated. Comprehensive improvement strategies are needed.

Existing adaptive e-learning methods are supported by student (user) profiling for capturing student characteristics, and course structuring for organizing learning materials according to topics and levels of difficulties. Adaptive courses are then generated by extracting materials from the course structure to match the criteria specified in the student profiles. In addition, to handle advanced...

Virtual Learning Environments (VLEs) such as Moodle help facilitate the management of educational courses for students, in particular by helping lecturers with course administration and students manage their own learning. However, even today problems still remain; in particular, e-learning environments provide a “one size fits all” approach to the learning process, where each student must follo...

The water cycle in the western United States changed dramatically over glacial cycles. In the past 20,000 years, higher precipitation caused desert lakes to form which have since dried out. Higher glacial precipitation has been hypothesized to result from a southward shift of Pacific winter storm tracks. We compared Pacific Ocean data to lake levels from the interior west and found that Great B...

The objective of this paper is to identify the incentives and barriers to marriage among cohabiting women, especially disadvantaged mothers who are targets of welfare reform. We use the newly released cohabitation data from the National Longitudinal Survey of Youth (1979-2000), which tracks the partners of cohabiting women across survey waves. Our results support several conclusions. First, coh...

This study was designed to investigate the effects of three countermeasures--landscaping, building a fence and prohibitive signs--on the frequency of trespassing, which in this case means crossing the track at places where it is forbidden. At each location the official route was no more than 300 m away. The main results showed that the effect of each countermeasure on the frequency of trespassi...
