Modern work is a highly social process, offering many cues for people to organize communication and access information. Shared physical workplaces provide natural support for tasks such as (a) <i>social reminding</i> about communication commitments and keeping track of collaborators and friends, and (b) <i>social data mining</i> of local(More)
In a few short years, we have witnessed a massive uptake in the use of cell phones, personal digital assistants and hybrid devices that integrate phone, computer and Internet services. These devices communicate with one another and with traditional computers. Along with the Internet, they have transformed our computational environments into communication(More)
The effects of nitric oxide (NO) on sperm motility were examined in the fathead minnow, Pimephelas promelas, using computer-assisted sperm analysis (CASA). The observed effects underscore the dual nature of NO as both a low-concentration regulatory agent and, at higher doses, a cytotoxic agent. At 1 x 10(-6) M concentration, NO donor sodium nitroprusside(More)

A fundamental unit for user interfaces to existing communications applications is the message. However, empirical studies showed that people typically see their communication in terms of other people they interact with and personal social networks. Furthermore, important tasks such as keeping in touch, or tracking communication status, are not well(More)
