Science in Focus: Shedding Light on Science: Workshop 7. Sun and Seasons
Light energy from the Sun is absorbed all over the Earth. In this workshop we will examine how the transformed energy heats the Earth unevenly, causing seasons.,The segment examines how the sun's path in the sky changes over the seasons, and how the tilt of the Earth's axis affects the number of daylight hours for people at different latitudes throughout the year.

Post-Conflict Reconstruction: Global Health Concerns and Issues A Public Health Seminar delivered by Candace Chandra, Founder and President, Canary Strategies, LLC on Monday, May 10, 2010 Due to the severity, length, and frequency of conflict around the world, global health is increasingly involved in post-conflict reconstruction. Conflict is increasingly impacting not just the burden of disease and prevalence of serious injuries (including mental health), but also destroying health care systems and physical infrastructure - creating an emergency

The Impact of Smoke-Free Workplace Laws on Acute Myocardial Infarction Deaths A Public Health Seminar delivered by Melanie Pickett on Monday, April 26, 2010. The rate of acute myocardial infarction (AMI) deaths in Massachusetts was examined before and after the implementation of a comprehensive smoke-free workplace law in July 2004. The impact of the state law in cities/towns with and without prior local smoking bans and the effect of the local laws were examined for the period 1999 through 2006. Following the implementation of the state law, there wa

Executive Compensation: More Regulation, or Just More Transparency?
The question of whether CEOs of America's major companies are overpaid has been a subject of interest for many years. Are the compensation practices for these elite men and women fair and appropriate? Do they provide proper incentives, or do they reward excessive caution or risk taking? Wharton accounting professors John Core and Wayne Guay have just completed a study on this topic. Guay, along with colleague Chris Armstrong, sat down with Knowledge@Wharton to discuss executive compensation and
Pre-Service Teacher Training in Mathematics Using Tablet PC Technology
This study focuses on the use of innovative Tablet PC technology in learning and teaching mathematics. Specifically the effects of incorporating Tablet PC technology in pre-service teachers' mathematics education were analyzed. The significant impact of technology use in mathematics education was assessed by evaluating and comparing students' final project and course grades. Grade performance of two groups of students was compared. One group was the treatment group where students extensively use
Online Library of Scientific Models - A New Way to Teach, Learn, and Share Learning Experience
While scientific models are usually communicated in paper format, the need to reprogram every model by every user results in a huge loss of efforts, time and money, hence lengthening the educational and research developing cycle and loosing the learning experience and expertise gained by every user. We demonstrate a new portal www.imodelit.com that hosts a library of scientific models for electrical engineers in the form of java applets. They are all conformal, informative, with strong input and
Developing SCORM-based Courses for Avicenna Virtual Campus
Avicenna Virtual Campus (AVC) is UNESCO-led, multi-cultural EUMEDIS pilot project. It involves partners from sixteen Euro-Mediterranean states. Each partner contributes through a node called Avicenna Knowledge Centre (AKC), which produces e-courses and e-learning objects. For seek of interoperability, partners setup a pedagogical standard to guide the production process of learning objects. Further more, researchers adopted and recommended SCORM as a standard model for structuring learning objec
ICT use in school: vision and performance measures
The implementation of ICT in schools requires a vision on ICT use in school, the formulation of clear strategic goals, and the planning and organisation of the use of ICT in school. The pursued goals are those points we want to reach for the learner by setting up ICT use in school. At the same time the pursued goals are the results of using ICT as expected by the stakeholders, being the learner, the teacher, the ICT coordinator, and on an indirect way the parents, the environment and the funding
Analyzing Sequential Data in Computer-Supported Collaborative Learning
Representations and changes between them play a major role in cognitive development (e.g., Vosniadou, & Brewer, 1992) and education (e.g., Hewson, Beeth, & Thorley, 1998). By definition, change of representations is also indispensable for collaborative work since a common understanding or shared knowledge can only be achieved by a partial convergence of the knowledge structures of the collaborating subjects. This articles presents and discusses knowledge tracking (KT), viz., an approach to analy
Parkinson Disease - Motor Exam - Muscle Strength Sub-exam - Patient 10
The patient is a 68-year-old Caucasian male admitted to the VA on February 27, 2002, because of severe tremors and inability to walk due to chronic Parkinson Disease. This gentleman had been living with Parkinson Disease for many years and apparently, in spite of prescribed medications, had not improved or was getting worse. He experiences tremors, drooling, an inability to walk, and difficulty swallowing. Recently he had been unable to take the full dose of his carbidopa/levodopa medication du
Computer literacy and inquiry learning: when geeks learn less
A low level of computer literacy has often been hypothesized as constituting a disadvantage in knowledge acquisition. However, within the field of computer-supported inquiry learning systematic investigations of these purported relations have not been conducted. This classroom study investigates the role of computer literacy (procedural computer-related knowledge, self-confidence in using the computer, and familiarity with computers) as a learning prerequisite for knowledge acquisition, and anal
From MASK Knowledge Management Methodology to Learning Activities Described with IMS LD
In this paper we present how the way knowledge capitalized using the Knowledge Management Mask methodology can be used to design E-learning activities by matching Mask models and the concepts proposed by the IMS-Learning Design modelling language. Our study consists in highlighting the e-learning aspects encapsulated in these MASK models carried out around a domain of activity, via a writing these elements in the description language IMS - Learning Design; in a preoccupation of reusability and r
