This article examines social movement leadership and how organizing tasks may be completed in online social movements.

Collective action theory, which is widely applied to explain human phenomena in which public goods are at stake, traditionally rests on at least two main tenets: that individuals confront discrete decisions about free riding and that formal organization is central to locating and contacting potential participants in collective action, motivating them, and coordinating their actions.

This informal essay addresses the current status and trajectory of media art and media technology. In formulating my ideas on these topics, I found myself being drawn away from my usual technical concerns, and increasingly to the sociology, economics, and political relationships of electronic media art and its modes of production and dissemination.

The multicast infrastructure has transitioned to a topology that now supports hierarchical routing. Instead of a flat virtual topology originally called the Multicast Backbone (MBone) there now exists a hierarchy where routing information is exchanged between autonomous systems (ASes). In today’s multicast infrastructure reachability problems are common. Unlike in the MBone, the possibility of limited connectivity between domains is now possible. In this paper, we present a system called {\it sdr-monitor}.

This field experiment examined the effects of the sex of Web site authors and Web site visitors on perceptions of the credibility of personal Web pages. Participants viewed male and female Web pages created for this study, patterned after personal pages on the Web, and assessed sponsor, message, and Web site credibility. Results revealed that men rated both message credibility and site credibility significantly higher than did women and that there was a significant interaction effect whereby opposite-sex credibility evaluations were higher than same-sex credibility evaluations.

As part of the English Department’s Transcriptions Project, directed by my colleague Alan Liu, I’ve joined with other faculty and grad students in teaching our students to use their core abilities to read and write so as to build web-pages that link their work to the resources and communities available through the World Wide Web. The events of 9/11 have dealt a powerful shock to this project. It is forcing us to ask difficult new questions about the utility and dangers of intelligent networks and the global communication of information.

Innovative Tools for Enhancing Learning and Assessment

The IP multicast infrastructure has transitioned to a topology that now supports hierarchical routing. Multicast network monitoring and management have become key requirements necessary for providing robust multicast operation. Monitoring services help to identify potential problems such as protocol shortcomings, implementation bugs or configuration errors. This type of monitoring often requires knowing the multicast tree topology. In this paper, we present a new approach, called tracetree, to discover tree topology in the source-to-receiver(s) direction using network forwarding state.

Exponentially growing data archives emphasize the need for efficient techniques and novel approaches to find and extract information. Information visualization has emerged in the Information Retrieval domain to facilitate access to large databases. This development acknowledges the need to focus on higher level cognitive processes in information seeking. Geographic depictions of large databases are increasingly based on the spatial metaphor. These representations are also known as spatialized views or information spaces.
