The document discusses research being conducted on virtual organizations and socio-technical systems supported by a National Science Foundation grant. It provides background on the grant recipients and their goal of understanding how virtual communication influences deliberations at different stages of the research and development process. The document then summarizes three research sites being studied: a fundamental research project on optical devices, a virtual R&D ecosystem compiling data on Alzheimer's disease, and the distributed development of a large video game. Key conversations and deliberations are defined and examples are given for each research site. Potential barriers to effective virtual conversations are discussed and coordination mechanisms across the R&D continuum are presented.
