Social tagging, as a recent approach for creating metadata, has caught the attention of library and information science researchers. Many researchers recommend incorporating social tagging into the library environment and combining folksonomies with formal classification. However, some researchers are concerned with the quality issues of social annotation because of its uncontrolled nature. In ...

The situations of nineteenth century dock workers and today’s immigrant day laborers bear striking similarities and challenges, especially for those seeking to organize them into labor unions. The obstacles confronting such organizing efforts also underscore the legitimate concerns many Americans have about the threats to social order posed by immigrants today.

We demonstrate how simple local rules, inspired by social insects, produce complex dynamic behaviors required for locomotion and navigation in modular selfrecon gurable robots. We show how systems made up of many modules respond dynamically to their environment, such as obstacles during navigation. We present control algorithms tested on simulation experiments of TeleCube, a new modular robot d...

Humanoid robots can serve as a direct approach to the acquisition of this type of competence, since a sufficiently sophisticated humanoid robot would be able to experience much of the world in the same way as humans. Currently, however, humanoid robots have very limited experience with the world due to obstacles ranging from mechanical design to social constraints on the use of autonomous robots.

There are many unexpected or unexpectedly difficult obstacles to deploying anonymous communications. Drawing on our experiences deploying Tor (the second-generation onion routing network), we describe social challenges and technical issues that must be faced in building, deploying, and sustaining a scalable, distributed, low-latency anonymity network.
