Spatial Assessment And Analysis Of Pollution Sources And Water Quality In The Bogue Falaya River And Abita River Watersheds, St. Tammany Parish, La, Chelsea Core

LSU Master's Theses

Watershed planning is an important ongoing process for enabling communities to repair polluted waterways and ensuring the health and vitality of waterways for future generations. This study defines a process to spatially track pollution sources entering into our waterways. An essential tool used in the watershed planning process is geographic information systems. It is important to gather spatial information to illustrate where all potential pollution sources are located within each watershed. The data for this study were assembled into a database and mapped to locate pollution sources including: commercial/small business wastewater treatment plants; subdivisions without community wastewater treatment; and individual …

Oysters And Catfish: Resource Exploitation At Rollins Shell Ring, Ft. George Island, Florida, Julie Ann Doucet

LSU Master's Theses

Detailed faunal analyses were conducted on two major subsistence resources, oysters and marine catfish, at Rollins Shell Ring, a Late Archaic (5000 – 3000 B.P.) site on the northeast coast of Florida. The focus of this investigation was on resource exploitation, and, specifically, whether there was evidence that oysters from this site were over-exploited. Three units from previous excavations at the site were selected for analysis, and represent the span of occupation recorded for this site. Measurements were obtained from oysters to determine habitat, and, along with shell height, were compared across time for any changes in the pattern of …

Accessibility To Public High Schools And School Performance In Metropolitan Baton Rouge, Louisiana 1990-2010, Shaun E. Williams

LSU Master's Theses

Education policies developed to initiate improvements to public school systems across Louisiana often result in a continuation or intensification of salient yet overlooked accessibility challenges. The public high school and its students have been particularly susceptible to these actions which have been sustained for decades within the state despite the increasing awareness of individual and community hardships connected to high school level inadequacies. Beyond isolated district studies or aggregate state reports, limited focus has been placed on student accessibility to public high schools or on responses of students and communities to processes which alter their access to area high schools. …

Accounting Comparability, Audit Effort And Audit Outcomes, Joseph Hongbo Zhang

LSU Doctoral Dissertations

The paper investigates the usefulness of accounting comparability for audit engagement. Comparability among peer firms in the same industry reflects the similarity and the relatedness of firms’ operating environment and accounting reporting. From two perspectives of “inherent business risk” and “external information efficiency”, comparability is helpful for auditors to assess client business risk and lowers the cost of information acquisition, processing, and testing. For a given firm, I hypothesize that the availability of information about comparable firms is helpful for auditors by improving audit accuracy and audit efficiency. The comparability proxy is based on a variety of measures including pair-wise …

De L'Autre Coté Du Periph': Les Lieux De L'Identité Dans Le Roman Feminin De Banlieue En France, Mame Fatou Niang

LSU Doctoral Dissertations

My dissertation “ De l’Autre Coté du Periph’: Les Lieux de l’Identité dans le Roman Féminin de Banlieue en France” examines the writings of young female authors from the French suburbs, known as the banlieues. Not to be confused with their American counterparts, French suburbs have recently emerged as spatialized emblems of violence, poverty and social unrest. Their perception as sites of massive immigration furthermore fueled fears of national identity loss. The riots of fall 2005 violently brought to the foreground tensions that had been simmering and illustrated the increasing division between the banlieues and the rest of French society. …

Ecological Speciation Of King Rails (Rallus Elegans) And Clapper Rails (Rallus Longirostris), James Michael Maley

LSU Doctoral Dissertations

Ecological speciation is a process involving adaptation to different environments leading to reproductive isolation between populations. Hybridization between Clapper and King rails (Rallus longirostris and R. elegans) is frequent but restricted to narrow bands of brackish marsh along the Gulf of Mexico and Atlantic coastlines of North America. In the second chapter I used mitochondrial and nuclear sequences to infer phylogenetic relationships in this species complex. The complex falls out into three distinct groups: South America; western North America; and eastern North America and the Caribbean. My results indicate that R. elegans as currently recognized is paraphyletic, with birds of …

Development And Characterization Of A Murine Model Of Rickettsia Parkeri Rickettsiosis, Britton Grasperge

LSU Doctoral Dissertations

Rickettsia parkeri, a member of the spotted fever group of Rickettsia, is the agent of an emerging rickettsiosis in the southeastern United States and South America. Despite increased recognition of human cases, limited information is available regarding infection of invertebrate and vertebrate hosts for this emerging tick-borne disease. Towards development of a viable transmission model and to further characterize the pathology associated with R. parkeri infection, inbred mouse strains (A/J, Balb/C, C3H/HeJ, and C3H/HeN) were intravenously and intradermally inoculated with R. parkeri. The C3H/HeJ strain of mice were identified as the most susceptible to R. parkeri infection and were found …

Soil Climate And Pedology Of The Transylvanian Plain, Romania, Beatrix Haggard

LSU Doctoral Dissertations

The Transylvanian Plain (TP) is a 395,000 ha region located in north-central Romania and is an area of agronomic importance in the region. The TP is characterized by hilly terrain, dissected by the Someş and Mureş Rivers. The terrain creates a unique situation when assessing pedology and soil temperature. Soils can change quickly across the landscape in the TP due to the terrain. To account for these differences, soil temperature was measured to predict soil temperatures as well as to evaluate growing conditions. Twenty stations were installed for a long-term temperature and pedology study. Pedons were described for morphological characterization …

Mechanisms Of Urban Influence On Precipitation In The Southeastern United States: Precipitation Enhancement, Storm Bifurcation, And Synoptic Characteristics, Anna Marie Trevino

LSU Doctoral Dissertations

The continual growth of urban areas increasingly affects the environment on various spatial scales. Land cover changes, combined with decreasing vegetative cover and addition of atmospheric aerosols, potentially lead to growing urban heat islands that alter the local moisture fluxes directly or indirectly, which in turn play a role in precipitation initiation and development. Some studies suggest that a region of enhanced rainfall exists downwind of the main urban area and that frontal systems decelerate as they reach areas of high urban development. Six urban areas within the southeastern United States were examined for possible urban precipitation enhancement: Atlanta, Birmingham, …

Exploring The Influence Of Civic Community Structures On Family Poverty In A Multilevel Context, Candice A. Myers

LSU Doctoral Dissertations

This dissertation integrates the civic community perspective and structuralist and individualist perspectives of poverty to assess the relationships between civic community structures and family poverty outcomes. The key contribution of this project to the larger bodies of civic community and poverty research is the use of a multilevel framework that accounts for both community context and family characteristics in shaping family poverty outcomes. This objective is carried out through a series of multilevel analyses wherein religious and economic civic community structures are examined in relation to various conceptualizations of family-level poverty. The first analysis examines the associations between religious-based measures …

Out Of Site But Not Out Of Mind: Submerged Prehistoric Landscapes On The Northwestern Gulf Of Mexico Outer Continental Shelf, Amanda M. Evans

LSU Doctoral Dissertations

Archaeological sites are more important than simply the artifacts they contain. Locations of human occupation and activity form a pattern that can provide information about perceptions of the landscape, decisions about resources, or preferences. Explaining this “perceived” environment is one of archaeology’s goals in explaining past human behavior. In order to address these goals, archaeologists must first identify elements of the “real” landscape, including the geographical environment, its resources, and evidence of human modification. Only after these real elements have been identified can the perceived environment be explored. On the outer continental shelf of the northwestern Gulf of Mexico, formerly …

Reflections On En-Teaching: Dewey, Heidegger And Lao Tzu, Jie Yu

LSU Doctoral Dissertations

Reflecting on my past two unsettling journeys of teaching in China and America produces questions about the teaching of truth in chapter one. The question of truth as it relates to the teacher’s role in the classroom raises not only issues of what and how we should teach, but challenges the very purpose of teaching. When I explored Martin Heidegger’s phenomenological perspective on (un)truth for insights into taken-for-granted assumptions about education and the purposes of teaching and learning, I noticed a strong resonance between his notion of “clearing” and the essential spirit of Taoism, “the Tao of inaction.” This led …

Country Of Illusion: Imagined Geographies And Transnational Connections In F. Scott Fitzgerald's America, Charles Mitchell Frye Iii

LSU Doctoral Dissertations

The two decades between World Wars I and II were a remarkably isolationist, xenophobic period in the history of American politics and culture. In the era’s literature, however, some US authors repurposed regional writing as a medium for rethinking conservative nationalism and for imagining their country’s place in the emerging global community. F. Scott Fitzgerald, whose career successes and failures mirrored the parabolic national pattern of Boom and Bust, was one such author. Though his works have seldom been interpreted through a regionalist lens, Fitzgerald lived in and wrote about every major American section, often planting tropes of transregional and …

Constructing Wilderness: The Nexus Of Preservation And Ocean-Space In The United States, Ryan Orgera

LSU Doctoral Dissertations

The ocean has long played a minor role in human geography; imagining it as natural space rather than an extractive space even less significant. This dissertation explores the most revered kind of American nature preservation: wilderness. Despite the millions of acres set aside as wilderness in the United States, no such designation exists for ocean-space as a discrete entity. Through the analysis of congressional hearings, bills, resolutions, public laws, and maps, this dissertation uncovers the complex constructs of the production of legal wilderness. Furthermore, it uncovers a novel vein of inquiry, that of the ocean as a preserved natural space. …

Gis-Based Urban Land Use Characterization And Population Modeling With Subpixel Information Measured From Remote Sensing Data, Quan Tang

LSU Doctoral Dissertations

This dissertation provides deeper understanding on the application of Vegetation-Impervious Surface-Soil (V-I-S) model in the urban land use characterization and population modeling, focusing on New Orleans area. Previous research on the V-I-S model used in urban land use classification emphasized on the accuracy improvement while ignoring the discussion of the stability of classifiers. I developed an evaluation framework by using randomization techniques and decision tree method to assess and compare the performance of classifiers and input features. The proposed evaluation framework is applied to demonstrate the superiority of V-I-S fractions and LST for urban land use classification. It could also …

A Discourse On Geospatial Technology Applications In Predictive Analytics And Evidence-Based Decision Support For Disaster Research And Management, Steven Matthew Ward

LSU Doctoral Dissertations

Continued population growth and development in vulnerable locations across the world are creating a new geography of hazards and disasters. Increasing storm frequencies coupled with unrelenting efforts to control flooding through structural means will undoubtedly intensify the intersection between flood hazards and humans. Accordingly, the baseline capacity of places to prepare for and rebound from disaster events adequately is negatively impacted. Hurricane Katrina brought this reality to the forefront of disaster science and management in 2005. Concurrent with the increased awareness of evolving hazardscapes has been the identification of deficiencies in how components of disasters are studied and managed. The …

Making News In 140 Characters: How The New Media Environment Is Changing Our Examination Of Audiences, Journalists, And Content, Ashley Elizabeth Kirzinger

LSU Doctoral Dissertations

This project answers the following questions: What does political reporting on social media look like? How is political journalists’ use of social media changing their relationships with sources and fellow political journalists? Triangulating qualitative and quantitative research methods (content analysis, social network analysis, and in-depth interviews) in an examination of Twitter, a social media platform popular among journalists, this project provides insight into how changes in media routines are affecting news content.

Amd&Art: Performativity And Participation In Ecological Remediation, Travis Paine Brisini

LSU Doctoral Dissertations

In this study, I examine and theorize AMD&ART, an artwork devoted to treating polluted water in Vintondale, PA. AMD&ART is much more than simply a water treatment facility, however. Each chapter of this document examines AMD&ART through the lens of a different body of scholarly literature: the literature associated with land art, Systems Theory, Network Theory, Companion Specieshood and others. The theoretical focus of this paper is the emergent importance of the concept of performativity—“that reiterative power of discourse to produce the phenomena that it regulates and constrains” (Butler, Bodies 2)—in the deconstruction of the binary division of “nature” and …

Examining The Relationship Between The Exchange Rate, Foreign Direct Investment And Trade, Shanta Parajuli

LSU Doctoral Dissertations

Extensive research has been carried out on the relationships among foreign direct investment (FDI), exports, the exchange rate, and economic growth. However, these research findings are mixed and inconclusive. Therefore, further research and discussion are needed on this topic. This study focused on Mexico, since it is one of the major FDI recipient countries in Latin America and much of its trade is a result of its free trade agreements. This study examines the relationship between FDI, exports, and economic growth in the context of FDI from developed to developing countries (Mexico). The second chapter analyzes the relationship of FDI …

Queer Utopian Geographies And Cold War Poetry, Brigitte Natalie Mccray

LSU Doctoral Dissertations

Queer Utopian Geographies and Cold War Poetry intervenes in the general narrative about Cold War culture, made even more famous by such recent popular shows like Mad Men and Pan Am, that describes the era as a repressed society in desperate need of liberation. While indeed Cold War America was a time of paranoia and loyalty oaths, even before the Stonewall Riots of 1969 gay men and lesbians found subtle ways to resist popular media and government discourse that perpetuated the myth that the homosexual was the anti-citizen. A number of gay men and lesbians traveled extensively to escape this …

British Identity And The German Other, William F. Bertolette

LSU Doctoral Dissertations

British identity evolved through conscious comparisons with foreigners as well as through the cultivation of indigenous social, economic and political institutions. The German other in nineteenth- and twentieth-century Britain, like the French other in previous centuries, provided a psychological path toward unity against a perceived common enemy. Because German stereotypes brought into sharp focus what the British believed themselves not to be, they provided a framework for defining Britishness beyond Britain’s own internal divisions of race, ethnicity, class, religion, gender and politics. Post-World War II devolution and European integration have since revived British internal national divisions. The image of innocuous …

Inside The Seed Of School Accountability: An African-Centered Analysis, Rodrick Lerone Jenkins

LSU Doctoral Dissertations

I use Marimba Ani’s Asili concept as defined in Yurugu to examine the school accountability model. By school accountability model, I mean the school model that consists of privately managed “public schools” regulated by state testing programs. I argue that school accountability is essentially oppressive and its success depends on the falsification of African and African American history. Ani explains that Asili is a Kiswalhili term meaning “beginning,” “origin,” “source,” “nature (in the sense of the ‘nature’ of a person or thing),” “essence,” or “fundamental principle.” Furthermore, Ani writes that seed is an “ubiquitous African analogical symbol in African philosophical …

LSU Doctoral Dissertations

This dissertation comprises an analysis of wind frequency and magnitude data and resulting sand transport for Cape Cod, Massachusetts; wind speed and wave height data for coastal Louisiana; and habitat classification and elevation data for a retrogradational barrier island in coastal Louisiana. Chapter 2 presents an analysis of wind data for Cape Cod, Massachusetts in which annual, seasonal, niño, and storm-related wind patterns were investigated to analyze the potential for aeolian sand transport in a blowout dune located on Cape Cod. Results indicate that wind patterns, drift potential, and drift direction are seasonal. Sand drift potential varies at specific locations …

An Object-Based Image Analysis Approach For Detecting Urban Impervious Surfaces, Amit Kulkarni

LSU Doctoral Dissertations

Impervious surfaces are manmade surfaces which are highly resistant to infiltration of water. Previous attempts to classify impervious surfaces from high spatial resolution imagery with pixel-based techniques have proven to be unsuitable for automated classification because of its high spectral variability and complex land covers in urban areas. Accurate and rapid classification of impervious surfaces would help in emergency management after extreme events like flooding, earthquakes, fires, tsunami, and hurricanes, by providing quick estimates and updated maps for emergency response. The objectives of this study were to: (1) compare classification accuracy between pixel-based and OBIA methods, (2) examine whether the …

Modeling The Spatial And Temporal Dynamics Of Coastal Marsh Birds, Bradley A. Pickens

LSU Doctoral Dissertations

Wetland birds are likely to be influenced by habitat at multiple spatial scales, yet few studies have investigated bird responses at both broad and fine scales. Northern Gulf Coast marshes are dynamic ecosystems, and they provide an ideal place to examine habitat across spatial and temporal scales. My research focused on the secretive marsh bird guild (i.e. bitterns, rails, gallinules, grebes) with an emphasis on the king rail (Rallus elegans), a species of high conservation concern. My objectives were to investigate the wetland bird-environment relationship across scales, and to model annual changes in bird distribution. Study sites were in the …

Southern Bellas: The Construction Of Mestiza Identity In Southern Narratives, Wendy Aimee Braun

LSU Doctoral Dissertations

This project analyzes representations and self-representations of Mestizas living in areas of the Deep South that lack a significant Latino presence. Incorporating a range of media, I take a comparative approach to Southern cultural narratives and propose a re-reading of these works through an examination of identity formation and cultural negotiation. By centering the Southern Mestiza, this dissertation advances concepts of intersectionality to address the role of region, as well as race and gender, in the representation and experiences of women often overlooked in Southern and U.S. Latino studies. The Introductory chapter summarizes the theoretical framework for the study, including …

Painting A Surrealist Case Study Tableau: Culturally Relevant Post-Disaster Education Programming, Jolanta Smolen Santana

LSU Doctoral Dissertations

This retrospective study explores how each disaster site needs to be considered as its own individual portrait for analysis and how inclusion of cultural elements contributes to the recovery of those affected by the disaster and helps in reinstating their cultural identity. This study was conducted after hurricane Katrina’s landfall, at the largest FEMA trailer park, Renaissance Village, from its inception in October 2005 until its closure June 2008. It portrays how programs may ensure their sustainability if cultural elements are included in the program design, development, and delivery of services. The nuanced notions of culture are predominantly recognized in …

Semantically-Aware Data Discovery And Placement In Collaborative Computing Environments, Xinqi Wang

LSU Doctoral Dissertations

As the size of scientific datasets and the demand for interdisciplinary collaboration grow in modern science, it becomes imperative that better ways of discovering and placing datasets generated across multiple disciplines be developed to facilitate interdisciplinary scientific research.

For discovering relevant data out of large-scale interdisciplinary datasets. The development and integration of cross-domain metadata is critical as metadata serves as the key guideline for organizing data. To develop and integrate cross-domain metadata management systems in interdisciplinary collaborative computing environment, three key issues need to be addressed: the development of a cross-domain metadata schema; the implementation of a metadata management system …

Negotiating Cultural Transitions: Contemporary Student Veterans And Louisiana Institutions Of Higher Education, Kay Harrison Maurin

LSU Doctoral Dissertations

Student veterans are flooding colleges and universities in numbers not seen since the end of World War II. Little is known about how these contemporary student veterans navigate the transition from military life to campus life. Few studies have documented the transition experiences of these student veterans by institution type or cultural region of the country. In Louisiana, nearly 7,000 students receive military benefits for higher education with this number steadily increasing (U.S. Department of Veterans Affairs, 2009, June). This study explores the transition experience of student veterans from military life to university life at four institutions of higher education …

Investigating The Role Of Genetic Variation In Long Run Economic Outcomes, Charles Justin Cook

LSU Doctoral Dissertations

This dissertation empirically tests whether adaptations resulting from the Neolithic Revolution, or the widespread adoption of sedentary agriculture for sustenance, have led to economic differences. The development of sedentary agriculture constituted an environmen- tal shift from the previous sustenance method of hunting and gathering. This environmental shift resulted in the natural selection of certain traits. I seek to exploit differences in these traits to measure differing economic outcomes. Two main adaptations are considered in this work: the ability to consume milk, or lactose tolerance, and resistance to infectious Eurasian diseases, which is the result of genetic variation. The first essay …
