This paper elaborates a multi-model approach to studying how local scenes
change. We refer to this as the "4 D's" of scene change: development,
differentiation, defense, and diffusion. Each posits somewhat distinct change
processes, and has its own tradition of theory and empirical research, which we
briefly review. After summarizing some major trends in scenes and amenities in
the US context, for each change model, we present some initial findings,
discussing data and methods throughout. Our overall goal is to point toward new
research arcs on change models of scenes, and to give some clear examples and
directions for how to think about and collect data to understand what makes
some scenes change, others not, why, and in what directions.Comment: Published at Journal Wuhan Universit
