We submitted a paper to the “unspoken borders 09″ conference at UPenn in April this year. The publication just came out and can be purchased here. It is a compilation of articles under the theme “Ecologies of Inequality”, an investigation of the systems, infrastructure, and design processes that create or perpetuate socio-economic and environmental stratification of our communities. This theme asserts that social inequities are unsustainable, not only in terms of socio-economic injustices, but also in regards to the amount of resources invested in maintaining or creating these inequalities.
