Method
A nexus framework for people, ideas, roles, and time
SENA connects Social Network Analysis, Epistemic Network Analysis, and SENS into one theory-aligned workflow.
What is SENA?
SENA models collaboration as a dynamic nexus: people, discourse moves, roles, communities, stages, scaffolding, and outcomes are analyzed together.
Why SNA alone is insufficient
SNA reveals participation, centrality, brokerage, reciprocity, and communities, but it cannot explain the epistemic content of interaction by itself.
Why ENA alone is insufficient
ENA reveals connections among concepts, codes, or reasoning moves, but it does not inherently explain social position, brokerage, or communities.
How SENA integrates SNA + ENA + SENS
SENA extends SENS into an end-to-end research workflow where social structure and epistemic structure become jointly interpretable evidence.
