Selective permeability in interdisciplinary knowledge organization: evidence from communication studies
摘要
Taking communication studies as a paradigmatic case, this study examines how interdisciplinary fields maintain disciplinary coherence while achieving sustained knowledge integration. Through analysis of 19,139 Web of Science papers (2000–2024) using Brillouin diversity indices, network analysis, and statistical validation, we reveal that communication studies has developed a hub-and-spoke architecture enabling selective permeability through three boundary-spanning mechanisms: conceptual bridging, methodological hybridization, and problem-driven convergence. Findings demonstrate differentiated integration between primary spokes (linguistics, sociology, psychology) and secondary spokes (biology, philosophy), with punctuated equilibrium dynamics across three technological transition periods. Drawing on Bourdieu’s field theory and Abbott’s jurisdictional analysis, we propose selective permeability as a transferable framework for understanding how interdisciplinary fields achieve innovation and coherence through structured knowledge integration.
