Policies Of Loss: Coastal Erosion And The Struggle To Save Louisiana's Wetlands, Rebecca B. Costa
Policies Of Loss: Coastal Erosion And The Struggle To Save Louisiana's Wetlands, Rebecca B. Costa
LSU Doctoral Dissertations
Since the 1930s, Louisiana has lost approximately 1,800 square miles of land due to the subsidence of the state’s coastal wetlands. By the early 1970s, public officials and private citizens were starting to become aware of the crisis on the coast, and a broad agreement developed among state and federal representatives that action was needed to address the problem. Over the course of nearly forty years, policymakers in Louisiana and Washington, D.C., implemented a series of laws and regulations meant to protect vulnerable ecosystems like the state’s wetlands. In the 1980s, officials also started crafting policies to help restore Louisiana’s …
The Mnemonic Maid: Joan Of Arc In Public Memory, Tara Beth Smithson
The Mnemonic Maid: Joan Of Arc In Public Memory, Tara Beth Smithson
LSU Doctoral Dissertations
This dissertation examines the relationship between Joan of Arc, postcolonial identity, and public memory. Since her repopularization in the nineteenth century, Joan of Arc has become one of the most emblematic figures of French history. Commemorated in public statuary, celebrated by writers, and championed by politicians, la Pucelle’s story is tantamount to national myth. While Joan of Arc’s centrality to France’s iconic imagining of itself during the spread of its empire has received much critical attention, her postcolonial afterlife remains understudied. This project offers a counterpoint to the prevailing assumption that Joan of Arc has few implications for postcolonial studies …
Re-Examining And Redefining The Concepts Of Community, Justice, And Masculinity In The Works Of René Depestre, Carlos Fuentes, And Ernest Gaines, Jacqueline Nicole Zimmer
Re-Examining And Redefining The Concepts Of Community, Justice, And Masculinity In The Works Of René Depestre, Carlos Fuentes, And Ernest Gaines, Jacqueline Nicole Zimmer
LSU Doctoral Dissertations
In La Communauté desoeuvrée (1983) French philosopher Jean-Luc Nancy describes how a community is creating by bringing its members together under a collective identity. The invention of myths, such as the myth of racial superiority and the mythic revolutionary community, functions to sustain the hegemonic dominance wielded in Haiti by the United States and later by François Duvalier, the Porfiriato and its aftermath in Mexico, and white society in the United States Deep South. These myths often engender policies founded in the inhospitable treatment of those who are deemed lesser or ‘other’. Nancy’s conception of being singular plural posits that …
Temporal Dynamics Of Benthic Responses To Habitat Disturbance In Coastal Plain Headwaters Of Southwestern Louisiana, Catherine Elizabeth Murphy
Temporal Dynamics Of Benthic Responses To Habitat Disturbance In Coastal Plain Headwaters Of Southwestern Louisiana, Catherine Elizabeth Murphy
LSU Doctoral Dissertations
Weak biotic responses to habitat gradients within Northern Gulf of Mexico streams have been attributed to spatial and temporal variability. Landscape and in-stream habitat descriptions are presented for watersheds within Pleistocene terraces of the Coastal Plains geomorphic province of Louisiana, USA. Geologic influences on stream habitat were inferred by comparing multivariate ordinations on physicochemical measurements between terraces. Seasonal variability was assessed during a drought year (2011) and a typical water year (2013). Within coastal plains of Louisiana, stream condition was more similar within terraces than within river basins. Permutational MANOVA models indicated significantly different stream habitat between Uplands and Prairie, …
Spatio-Temporal Modeling Of Louisiana Land Subsidence Using High Resolution Geo-Spatial Data, Hanyu Xiang
Spatio-Temporal Modeling Of Louisiana Land Subsidence Using High Resolution Geo-Spatial Data, Hanyu Xiang
LSU Doctoral Dissertations
Problems caused by subsidence are very common in many areas of the world, and this kind of problems may be serious and threatening to living people in Louisiana. Adverse subsidence in Louisiana will cause serious problems, such as excessive wetland formation or land loss, if we can’t make appropriate treatments, and this topic will also be what we focus on in this research (Kent and Dokka 2012). For subsidence survey, we can use three kinds of common techniques, leveling, InSAR (Interferometric Synthetic Aperture Radar) and GPS observation (Lu, C. et al. 2012). In this research, high accuracy of subsidence data …
Ant Diversity And Community Structure In Coastal Dunes And Wetlands, Xuan Chen
Ant Diversity And Community Structure In Coastal Dunes And Wetlands, Xuan Chen
LSU Doctoral Dissertations
How do many species live in a certain place? How does species composition changes among habitats? And what mechanisms decide species distribution? These are fundamental questions in community ecology. I first investigated ant diversity in two coastal ecosystems (dunes and wetlands) in the northern Gulf of Mexico, and then used the distribution patterns to infer assembly processes that structure ant communities in coastal areas. Specifically, the following hypotheses are tested: (1) coastal systems support lower ant diversity due to the unsuitable environment; (2) species living near the seashore are a subset of those exist near inland; (3) deterministic processes are …
