This second round of concentration revisions has been (thankfully) far less intensive than the first, with only relatively minor revisions necessary. The ENVS Steering Committee gave me several pieces of constructive feedback on my concentration, largely centered on the situated context I have chosen. They took issue with my treatment of gentrification, and advised me to make the theories behind gentrification more apparent in my summary. Upon reflection, I realized that I did need to pick apart the term slightly, in order to look at the potential drivers and more concrete connections with transportation planning. I already had the source to provide such a summary of the academic disagreements on this subject, and provided a sentence or two on how gentrification is driven by a combination of production-side (disinvestment, and reinvestment to collect greater rents) and consumption-side (increase in middle-class desires for an urban aesthetic) causes. The steering committee also advised me to make the direction of causality between transportation and gentrification more apparent. In my view, the relationship is not simply one-directionally causal; transportation infrastructure directs the geography of gentrification (with both consumption and production-side forces in play), but gentrification has its own marked effects on the transportation politics, and thus on the transportation infrastructure. These two are closely linked, and it is the existence of the former causal aspect that generates the latter.
