🤖 AI Summary
This study investigates the emergence and diffusion mechanisms of “vogue topics” in U.S. sociological knowledge production from 2011 to 2020. Methodologically, it constructs a dynamic semantic network from abstracts of doctoral dissertations and journal articles across 114 Ph.D.-granting institutions—bypassing conventional citation- or co-authorship-based approaches—to trace how word-pair associations migrate from peripheral to central positions over time. Results reveal that applied themes (e.g., crime, health) dominate trend diffusion, whereas theoretical topics play a subordinate role; institutional prestige and geographic location significantly shape both trend generation and adoption, yet elite institutions do not unidirectionally lead diffusion; and knowledge dissemination follows a专业化 stratified structure driven by contextual institutional factors rather than simple top-down propagation. The study contributes a novel methodological framework for modeling disciplinary knowledge dynamics and provides robust empirical evidence on the socio-institutional drivers of topical change in sociology.
📝 Abstract
This study investigates the social dynamics of knowledge production in American sociology. Departing from traditional approaches focused on citations, co-authorship, and faculty hiring, we introduce a method capturing the dynamics of networks inferred from text to explore which ideas gain traction (a.k.a vogue). Drawing on sociology doctoral dissertations and journal abstracts, we trace the movement of word pairs between peripheral and core semantic networks to uncover dominant themes and methodological trajectories. Our findings demonstrate that regional location and institutional prestige play critical roles in shaping the production and adoption of research trends across 114 sociology PhD-granting institutions in the United States. We show that applied research topics, such as crime and health, despite being perceived as less prestigious than theoretically oriented subjects, serve as the primary driving force behind the emergence and diffusion of trends within the discipline. This work sheds light on the institutional mechanisms that govern knowledge production, demonstrating that sociology's intellectual landscape is not dictated by simple top-down diffusion from elite institutions but is instead structured by the contextual and institutional factors that facilitate specialization and segmentation.
