Interaction, Mediation, and Ties: An Analytic Hierarchy for Socio-Technical Systems

Daniel D Suthers
2011 2011 44th Hawaii International Conference on System Sciences  
Transitive closure of associograms yields sociograms, to which existing network analytic techniques may be applied. We discuss how the hierarchy bridges between theoretical levels of analysis.  ...  To understand how technological designs encourage synergistic encounters between people and ideas within socio-technical systems, techniques are needed to bridge between levels of description from process  ...  Thus they bridge between interaction data and networks to which existing network analytic techniques may be applied.  ...
