This book reveals how advances in computer science and human-computer interaction impact Computer-Supported Collaborative Learning (CSCL) environments. The underlying theme of the contributions is the social affordances of physical objects. The collaborative situations illustrated in the book are not necessarily learning situation in a school sense. In summary, this book illustrates a turn in the field of CSCL and emphasizes an important message for a generation of CSCL users.

The frontier represented by the near solar system confronts humanity with intriguing challenges and opportunities. With the inception of the Human Exploration and Development of Space (HEDS) enterprise in 1995, NASA has acknowledged the opportunities and has accepted the very significant challenges. Microgravity Research in Support of Technologies for the Human Exploration and Development of Space and Planetary Bodies was commissioned by NASA to assist it in coordinating the scientific information relevant to anticipating, identifying, and solving the technical problems that must be addressed throughout the HEDS program over the coming decades. This report assesses scientific and related technological issues facing NASA's Human Exploration and Development of Space endeavor, looking specifically at mission enabling and enhancing technologies which, for development, require an improved understanding of fluid and material behavior in a reduced gravity environment.

First published in 1993, the Role of Beta Receptor Agonist Therapy in Asthma Mortality provides the first comprehensive review of the role of beta-receptor agonist drug therapy and asthma mortality. The book includes sections on the epidemiological and experimental methods used to examine possible relationships between beta-agonist drug therapy and asthma mortality. It also reviews the development of beta-agonist drugs and the long-term trends in asthma mortality to present a historical perspective. Internationally respected experts have contributed to this unique volume, making it essential for epidemiologists, pharmacologists, and researchers in clinical medicine and public health.
