The Web site offers visitors information on space science missions including the Living with a Star and Solar Terrestrial Probes mission. Meeting notes and official reports can be viewed online, including the Sun Earth Connection 2002 Strategic Plan. Other items of interest include informat
LSE Literary Festival - Dance, Text, and Translation: Creating a Dialogue
Dance is generally concerned with non-verbal bodily communication, while literature is text-based and disembodied. However, the long relationship between dance and text has been explored both through textual interfaces by collapsing the boundaries between different art forms such as physical theatre, dance and literature and within the world of text, these boundaries are negotiated through the body of literature written about dance.
GEM: Greener Education Materials for Chemists
This site is a resource for green chemistry principles and literature. It provides links for making green organic experiments and teaching the principles of green synthesis. Although it does not have many links specifically to chemical analysis, it provides an extensive overview and source of information regarding the important area of green chemistry.
Notes on Bioanalytical Chemistry Lectures
Short lecture notes and support materials for a course in bioanalytical chemistry. Examples of topics covered include isolating and sequencing DNA, DNA chips, data reduction and analysis, biochemistry on the micro to nano scale, genomics and proteomics, and biochemical ethics.
Middle School Portal: Math and Science Pathways (MSP2)
In this interactive exercise, students in grade 6 and up determine if a Mars rover should look for evidence of life on or underneath the Martian surface. To make this determination, students process visual and textual information about how four factors (cosmic radiation, ultraviolet radiation, temperature, and presence of water) impact Earth and Mars. They look at each factor in isolation by reading a brief explanation of its effect on life, analyzing cartoon-like images of its influence on Eart
Future Directions in the Law Regulating Weaponry in Armed Conflict
A discussion on future directions in the law regulating weaponry in armed conflict to mark the release of Bill Boothby's new book Weapons and the Law of Armed Conflict. Bill Boothby has served for 27 years as an officer in the Royal Air Force legal branch. He developed and implemented the British system for the legal review of new weapons, and formed and led the team charged with conducting these reviews. Tom Porteus is London director of Human Rights Watch.

Readings in the History of Aesthetics
Anyone with connection to the Internet has access to a vast number of philosophical documents via online etexts. Fortunately, quite a bit of the best work in philosophy is in the public domain, and a few of these readings provide a convenient access for almost anyone seeking information and help in the history of aesthetics. However, many of the historically significant writings in aesthetics are not presently available on the Internet, and this open source text helps somewhat to remedy that nee
Carbon on the Move
Through a reading, demonstration stations, and completion of a puzzle, students will recognize how respiration and photosynthesis move carbon through the earth system, how fossil fuels were formed, and how human activities have altered this movement on a global scale.
Patient Race/Ethnicity and Quality of Patient–Physician Communication During Medical Visits
Objectives. We examined the association between patient race/ethnicity and patient–physician communication during medical visits. Methods. We used audiotape and questionnaire data collected in 1998 and 2002 to determine whether the quality of medical-visit communication differs among African American versus White patients. We analyzed data from 458 African American and White patients who visited 61 physicians in the Baltimore, Md–Washington, DC–Northern Virginia metropolitan area. Outcome
The Redistricting Game is designed to educate, engage and empower citizens around the issue of political redistricting. Currently, the political system in most states allows the state legislators themselves to draw the lines. This system is subject to a wide range of abuses and manipulations that encourage incumbents to draw districts which protect their seats rather than risk an open contest. By explore how the system works, as well as how open it is to abuse, The Redistricting Game allows play

Characterization of adhesives at room and elevated temperatures
Recent interest in advanced materials has paved the way for exploring joining options besides the traditional mechanical or thermal methods such as riveting or welding. Because of the availability of highly advanced materials, mass production rates and demands for more aesthetic products, adhesive bonding is being used in more applications. Today, interstate signs, semi-trailer panels, aircraft structures, and many other commonly used products are adhesively bonded. Some of the common misconcept

Seven boys who had received intervention for highly unintelligible speech were tested for metaphonological awareness skills and alphabetic knowledge at the beginning of the summer prior to their entering kindergarten. Five of these boys participated in 12 small-group [2-hour] sessions that incorporated lessons from a comprehensive multisensory early literacy program. Two of the seven boys were not able to participate in the sessions because of summer activity conflicts. Post-treatment scores wer
