Novel communication technologies significantly influence proactive behaviours by expanding and developing information highways and using satellite and computer facilities in the world. These influences can be examined in political, social, economic, and cultural aspects and so on. The main purpose of current research is to study the cyberspace role in political development from the student's vi...

This study aimed to evaluate the effectiveness of an intervention to reduce bicycle injuries among rural middle school students in China. A one-year cluster-randomized controlled trial was conducted with seventh grade students from six middle schools in two towns in rural Chaoshan, China. The two towns were randomly assigned to either the intervention or control group. Road safety education mat...

background and purpose: communication skills play an important role in diagnosis, effective treatment, and patient satisfaction. we aimed to determine the attitudes of medical students towards learning communication skills in order to design related educational programs for them. methods: this was a cross-sectional study with a sample of 200 medical students of yazd that were selected using cla...

Teaching college students about the nature of science should not be a controversial exercise. College students are expected to distinguish between astronomy and astrology, chemistry and alchemy, evolution and creationism. In practice, however, the conflict between creationism and the nature of science may create controversy in the classroom, even walkouts, when the subject of evolution is raise...

Lafayette College, with strong programs in engineering and the liberal arts, requires sophomore students to enroll in a “VaST” (Values and Science/Technology) course. These courses incorporate approaches from the engineering viewpoint and ideas from the social sciences and humanities. As a result of taking a VaST course, students should be better able to see and understand engineering and scien...

In this paper we present the geometry and the algorithms for organizing a viewer-centered representation of the occluding contour of polyhedra. The contour is computed from a polyhedral boundary model as it would appear under orthographic projection into the image plane from every viewpoint on the view sphere. Using this representation , we show how to derive constraints on regions in viewpoint...

This is a survey on our work generalizing the classical Dehn-Sommerville equations (analogous to Poincaré duality, see [10]) for f -vectors of triangulations of manifolds without boundary to general polyhedra. Our key observation is that the exact data needed for the generalization is the classification of points of polyhedra by the Euler characteristics of their links. From this viewpoint, a p...

Background: In the present study, we studied the clinical students’ viewpoints toward traditional and case study training methods. Methods: This analytical descriptive study was conducted in cardiac ward of ValiAsr Hospital in Birjand from 1389 to 1390. 5 training sessions in the form of case presentation were held during a one-month course in cardiac ward. The trainer prepared a PowerPoint fi...
