The Impact of Primary Care on Population Health
This lecture summarizes Professor Leiyu Shi's recent work on primary care, the definition of primary care, and his research rationale and framework. It includes a close look at international primary care studies, US primary care studies, Metropolitan Statistical Area analyses, county-level studies, multi-level studies, meta-analyses, and US health center studies.
Investigating mental representations in children interacting with small mobile robots
This research aimed at investigating the acquisition of comprehension of a robotic system in school age children by using two different methods: concept maps and interviews. We demonstrated that concept maps are an important instrument of verification of knowledge, offering the possibility to graphically re-examine the expressed knowledge, and training children to decompose a problem (analysis) and re-compose it in a more structured way (synthesis). The interviews confirmed the subjectsÂ’ abilit

The European Space Agency mission, International Gamma-Ray Astrophysics Laboratory (INTEGRAL), was developed to gather the Universe's energetic radiation in order to better understand the most violent processes in the Universe. After reading the in-depth descriptions about INTEGRAL, users can learn the latest INTEGRAL news and view the monthly and archived image. Visitors will find plenty of help, information on workshops and conferences, and downloadable publications. The website provides detai
Promoting Self-Directed Learning in Simulation Based Discovery Learning Environments Through Intell
Providing learners with computer-generated feedback on their learning process in simulation-based discovery environments cannot be based on a detailed model of the learning process due to the "open" character of discovery learning. This paper describes a method for generating adaptive feedback for discovery learning based on an "opportunistic" learning model that takes the current hypothesis of the learner and the experiments performed to test this hypothesis as input. The method was applied in
Gridcole: a tailorable grid service based system that supports scripted collaborative learning
This paper introduces Gridcole, a new system that can be easily tailored by educators in order to support the realization of scripted collaborative learning situations. To do so, educators can provide a script specifying the sequence of activities to be performed by learners as well as the tools and documents required to support them. Gridcole can then search for these tools in a service-oriented grid in order to integrate them so that they are available for users during the realization of the s

This site, posted by the US Department of Energy's Sandia National Laboratories, "provides access to a comprehensive set of databases on metal-hydrogen systems, their properties, applications, literature sources, and profiles of organizations involved in metal-hydrogen development." Metal hydrides are important because they are commonly used in batteries and as hydrogen fuel storage cells for autos and power generation (a fossil fuel alternative). The technical part of the database has hydride m

War zones and hostile environments often prevent press coverage of important events, such as the Gulf War and, more recently, the dealings with Al Qaeda in Afghanistan. A new invention, called the Afghan Explorer, could solve this problem. It is, in essence, a robotic journalist. With the capability to maneuver, record audio and video footage, and conduct interviews, the Afghan Explorer can provide coverage of military situations and off-limit areas with no risk of human casualties. The mobile "

Electronic sensors exist in many facets of our lives, from measuring operating conditions of our vehicles to adjusting the temperature of our homes. They can even mean the difference between life and death when used to monitor patients in emergency rooms. Even though sensors work transparently in their multitude of functions, their importance cannot be understated.Sensorland (1) has basic descriptions of a wide variety of sensors and related concepts. Out of the 50 items in the list, some have f

Engaging in social issues in today's society requires an understanding of numerical data, statistics, and mathematical assumptions that underlie discussions about the federal budget, the spread of disease and other issues. However, the mathematics and the social issues are often considered in isolation and leave many Americans "ill-prepared to make informed decisions." The Thinking with Data Project is a new initiative of the National Science Foundation, SRI International, Kent State University
Jurisdiction in Cyberspace
At its core, jurisdiction is about the boundaries of a sovereign's exercise of its power. What are reasonable constraints on its reach, such that faraway or otherwise unconnected people and institutions can be called to account by the sovereign? Closely related are concepts of choice of law - exactly which sovereign's law to apply to a situation that spans multiple jurisdictions - and venue, which determines the physical location in which the parties are best served to settle their dispute.

Verbal and Nonverbal communication in computer mediated settings
The paper discusses the verbal and nonverbal communication during a video-recorded meeting between two physically separate teams as part of a 9 month multi-site construction project. In the extract analysed here, the team which was video-recorded contained three members and the project coordinator, whereas the remote team contained a single individual. Communication between the two teams was by means of telephone and shared computer meeting system. The video-recorded team used nonverbal communic
