 (2010) developed a framework that describes the relationships between these multiple velocity dimensions, noting that they may each have a distinct and often different velocity.They define “velocity homology” as the degree to which velocity dimensions have similar rates and directions of change and “velocity coupling” as the degree to which the velocities of different dimensions affect one another.This multidimensional treatment of environmental velocity results in four “velocity regimes” - simple, divergent, conflicted and integrated - based on the patterns of velocity homology and velocity coupling.
