Grid computing allows large groups of computers (either in a lab, or remote and connected only by the Internet) to extend extra processing power to each individual computer to work on components of a complex request. Grid middleware, recognizing priorities set by systems administrators, allows the grid to identify and use this power without…

Discusses the management perspectives of the transition to distributed support services for information technology at Rice University (Texas), focusing on the implementation process, changes that were required in migrating from a strong centralized organization to a distributed model, and the challenges encountered in the implementation.

Examines the use of chaos theory in modelling time series data generated by computer-mediated communication (CMC). Data generated by CMC discussion groups are examined for the presence of chaotic behavior and to assess the variance which can be accounted for by the deterministic mechanism. (Author/LRW)

Online users leave traces that others can find and use. Provides an overview of where and how users leave traces and what users can do to protect their privacy. Discusses Internet accounts; special files ("signature,""plan,""project,""file,""finger,""whois," and "vacation");…
