Beyond CUDOS and DECAY: Mapping Research Norms With an Institutional Logics Wheel
European Journal of Education, Volume 61, Issue 2, June 2026.ABSTRACT The normative landscape of academic research is increasingly fragmented. Classical CUDOS norms and counternorms coexist across profession, market, corporation, state and community logics, yet existing scholarship rarely explains how these norms are patterned, how they interact, or how tensions between them are mediated. This conceptual article
