This one-day workshop invites discussion on the various socio-technical processes and dynamics that characterize scale and scaling in local, community-sited initiatives. Seeking to move beyond a view of scale as mere growth in numbers and a matter of technology-mediated replication, the workshop aims at developing a nuanced vocabulary to talk about various forms of scale and practices of scaling in CSCW research. It will bring together interdisciplinary scholars, activists, practitioners and representatives of the public sector who wish to question and further develop the notion of scale generally associated with processes of upscaling. The workshop provides a forum to discuss:i) concepts, theories and empirical cases that broaden our view of what constitutes scale; andii) the implications for CSCW research in assessing the long-term impact and sustenance of socio-technical innovations. The workshop will accommodate up to twenty participants and will be run virtually.
