Description: The dissertation is a philosophical approach to politicizing place and space, or environments broadly construed, that is motivated by three questions. How can geography be employed to analyze the spatialities of environmental justice? How do spatial concepts inform understandings of environmentalism? And, how can geography help overcome social/political philosophy's redistribution-recognition debate in a way that accounts for the multiscalar dimensions of environmental justice? Accordingly, the dissertation's objective is threefold. First, I develop a critical geography framework that explores the spatialities of environmental injustices as they pertain to economic marginalization across spaces of inequitable distribution, cultural subordination in places of misrecognition, and political exclusion from public places of deliberation and policy. Place and space are relationally constituted by intricate networks of social relations, cultural practices, socioecological flows, and political-economic processes, and I contend that urban and natural environments are best represented as "places-in-space." Second, I argue that spatial frameworks and environmental discourses interlock because conceptualizations of place and space affect how environments are perceived, serve as framing devices to identify environmental issues, and entail different solutions to problems. In the midst of demonstrating how the racialization of place upholds inequitable distributions of pollution burdens, I introduce notions of "social location" and ...

Description: N-acyl ethanolamines (NAEs) are a class of lipids recently recognized as signaling molecules which are controlled, in part, by their degradation by fatty acid amide hydrolase (FAAH). On the basis of previous studies indicating increased NAE levels in a tobacco cell suspension-xylanase elicitor exposure system and the availability of FAAH mutants, overexpressor and knockout (OE and KO) genotypes in Arabidopsis thaliana, further roles of NAEs in A. thaliana plant defense was investigated. The commonly occurring urban antimicrobial contaminant triclosan (TCS) has been shown to suppress lipid signaling associated with plant defense responses. Thus, a second objective of this study was to determine if TCS exposure specifically interferes with NAE levels. No changes in steady state NAE profiles in A. thaliana-Pseudomonas syringae pv. syringae and A. thaliana-flagellin (bacterial peptide, flg22) challenge systems were seen despite evidence that defense responses were activated in these systems. There was a significant drop in enoyl-ACP reductase (ENR) enzyme activity, which catalyzes the last step in the fatty acid biosynthesis pathway in plants, on exposure of the seedlings to TCS at 10 ppm for 24 h and decreased reactive oxygen species (ROS) production due to flg22 in long term exposure of 0.1 ppm and short term ...

Description: This set of volumes is a response by the EPA to ten petitions filed to challenge the determination that climate change is real. The EPA dismisses the petitioners' claims, reiterating the evidence of anthropogenic global climate change.

Description: This order establishes a national policy to ensure the protection, maintenance, and restoration of the health of ocean, coastal, and Great Lakes ecosystems and resources, enhance the sustainability of ocean and coastal economies, preserve maritime heritage, support sustainable uses and access, provide for adaptive management to enhance understanding of and capacity to respond to climate change and ocean acidification, and coordinate with national security and foreign policy interests. This order also provides for the development of coastal and marine spatial plans that build upon and improve existing Federal, State, tribal, local, and regional decision making and planning processes.
