A city and its river: an urban political ecology of the Loop and Bridgeport in Chicago

Today’s urban environment is produced, both physically and perceptually, by a myriad of factors. Through a comparative study of two Chicago neighborhoods along the Chicago River, the Loop and Bridgeport, I construct the network of political, social, and economic factors that create the urban environment of the Chicago River in and along these places. I explore residents’ perception of who controls the production of the urban environment as it relates to the Chicago River, and how the socio-environment is created. In this study, I utilize an urban political ecology approach that recognizes that environments produced simultaneously by social and physical processes are historically situated and that there is nothing inherently unnatural about urban, produced environments, but that these environments are a result of historically and spatially contextualized socio-environmental processes. Using this approach in conjunction with interviews, surveys, and participant observation, I analyze these factors to determine who the residents of these neighborhoods perceive as exerting control over the production of the environment of the Chicago River and how these various entities, along with the numerous processes that influence the environment of the river, are mobilized to serve particular purposes. This research allows me to view the interrelated entities that contribute to the production of the environment of the Chicago River as well as to understand that social factors and pressures that have both historically and recently played a larger role in this production than are often ascribed to them by residents

A Variational Approach to Particles in Lipid Membranes

A variety of models for the membrane-mediated interaction of particles in lipid membranes, mostly well-established in theoretical physics, is reviewed from a mathematical perspective. We provide mathematically consistent formulations in a variational framework, relate apparently different modelling approaches in terms of successive approximation, and investigate existence and uniqueness. Numerical computations illustrate that the new variational formulations are directly accessible to effective numerical methods
