Climate Change Displacement And Global Governance: A Case Study Of Three Intergovernmental Organizations And The Conflict Between The Member States And Bureaucracy, Andrea C. S. Berringer Jan 2011

Climate Change Displacement And Global Governance: A Case Study Of Three Intergovernmental Organizations And The Conflict Between The Member States And Bureaucracy, Andrea C. S. Berringer

LSU Doctoral Dissertations

Climate change is a topic most often broached by environmental scientists and activists and its effects are discussed in terms of animal populations and atmospheric events. However, its direct effect on human life is yet to garner such attention. A changing climate will affect how people are able to use their environment, if at all. Sea level rise and desertification will force a shift in human habitation. How the world seeks to deal with this shift is yet to be seen. The global governance of climate change-induced displacement is currently at the stage of ad hoc development. Legal and conceptual …

Improving Math Instruction In Schools That Serve The Poor, John, L. Jr. Sims Jan 2011

Improving Math Instruction In Schools That Serve The Poor, John, L. Jr. Sims

LSU Master's Theses

Public alarm concerning how well U.S. schools are performing in mathematics compared to other developed nations is increasing. Reports of inadequate teaching, poor curriculum design, and low performance on standardized test have been fueled by the media. These issues in American mathematics classrooms are far compounded in schools that serve the poorest in America. When comparing mathematical proficiency rates of U.S. schools with other countries, schools with less than 25% free and reduced lunch score competitively with counterparts in other countries. In contrast, schools with rates of free and reduced lunch higher than 50% score dismally in comparison. Conditions such …

Modern Myth In Performance: Claiming Identity Through A Reading Of Fantasy Withcraft, Jessica Satterwhite Gray Jan 2011

Modern Myth In Performance: Claiming Identity Through A Reading Of Fantasy Withcraft, Jessica Satterwhite Gray

LSU Doctoral Dissertations

In this dissertation, I create a Wiccan dramaturgical lens to analyze three key fantasy sites: The Wizard of Oz film and stage adaptations (especially the Broadway musical Wicked), The Chronicles of Narnia film and theatrical adaptations, and the Harry Potter films and paratheatrical adaptations. These three fantasy stories have significant cultural impact and strong images of folkloric witches. My alternative reading shows how a subgroup can appropriate popular images for their own identity formation. I will analyze how signs, themes, and narrative tropes that otherwise seem ancillary or even anti-witch become highlighted and privileged, creating a different but equally legitimate …

Situation Comedies And The Single Woman On Television, Ashli Leeann Dykes Jan 2011

Situation Comedies And The Single Woman On Television, Ashli Leeann Dykes

LSU Doctoral Dissertations

Through an historical overview of the never-married female character in twentieth century situation comedies and an in-depth analysis of three twenty-first century American sitcoms, this dissertation investigates how television creators, writers, producers, and actors have interpreted the figure of the single woman and attempted to make her appealing and acceptable to a broad viewing audience. Because of its traditionally family-friendly offerings and preponderance of female characters in comparison to other popular culture genres, the situation comedy presents a significant case study for the analysis of female representations on television. Through its encouraged identification with characters and portrayals of issues that …

"We Live In A Used World": Cultural Geographies Of American Garage Sales, Gentry Powell Hanks Jan 2011

"We Live In A Used World": Cultural Geographies Of American Garage Sales, Gentry Powell Hanks

LSU Master's Theses

This thesis seeks to understand the emotional geographies of American garage sales, which I argue are liminal. Through a methodology of narrative surveys (open-ended questionnaires), mental maps, participant-observation, and interviews, I make the case that garage sales, through absent and/or present items, narratives, and exchanged histories, can reveal much in terms of identity, values, and cultural practices. These archives on the margins hold stories, artifacts, and performances of a distant or near past, giving geographers an innovative lens through which to explore the intricacies of materiality, place, and representation. This thesis provides a range of theoretical and practical perspectives on …

Transport Properties Of Nanometer-Sized Assemblies Through Nanofluidic Channels With Single Entity Electrical Detection, Franklin Ifeanyichukwu Uba Jan 2011

Transport Properties Of Nanometer-Sized Assemblies Through Nanofluidic Channels With Single Entity Electrical Detection, Franklin Ifeanyichukwu Uba

LSU Master's Theses

Recently, there have been reports on biological and solid-state nanopores that identify single biopolymers or their constituent monomers by analyzing changes in ionic current blockades when they block the flux of buffer ions while travelling through the nanopores. Nevertheless, there have been several limitations in their application, especially as DNA detectors; Poor confinement of the DNA strand within the nanopore (~0.1 % of a 10 kilobase (kb) DNA), poor signal sensitivity and random motion experienced by the DNA in solution that results in a large amount of noise in the signal. These have led to the development of nanochannel-based devices, …

Modeling Effects Of Coupled Convection And Co2 Injection In Stimulating Geopressured Geothermal Reservoirs, Tatyana Plaksina Jan 2011

Modeling Effects Of Coupled Convection And Co2 Injection In Stimulating Geopressured Geothermal Reservoirs, Tatyana Plaksina

LSU Master's Theses

Geopressured geothermal brines are a vast geothermal resource in the US Gulf of Mexico region. In particular, geopressured sandstones near salt domes are potential sources of geothermal energy because salt diapirs with high thermal conductivities may pierce younger, cooler strata. These characteristics enhance transfer heat from older, hotter strata at the base of the diapir into shallower strata. Moreover, widespread geopressure in the Gulf region tends to preserve permeability, enhancing productivity. As an example, the Camerina A sand of South Louisiana was chosen as a geomodel for a numerical simulation study of effects of CO2 injection and coupled convection as …

Indexing And Economic News: Coverage Of The 2009 Economic Stimulus Debate, Portia Levasseur Jan 2011

Indexing And Economic News: Coverage Of The 2009 Economic Stimulus Debate, Portia Levasseur

LSU Master's Theses

Indexing theory predicts that, in certain issue areas, media coverage will index levels of elite debate. Elite controversy, the theory predicts, will embolden the press to include a broader variety of sources and coverage should reflect a more open public debate. This has important implications for public opinion. Proponents of the theory expect that it will operate in a variety of issue areas of news coverage, but support for the theory exists largely in the realm of foreign affairs coverage. This study examines television coverage of the 2009 economic stimulus package to evaluate levels of indexing for a domestic, macroeconomic …

"The Prince And His People": A Study Of Edwardian Propaganda, 1547-1549, Allison Claire Cooper Jan 2011

"The Prince And His People": A Study Of Edwardian Propaganda, 1547-1549, Allison Claire Cooper

LSU Master's Theses

One of the most important events of Edward VI’s reign, the 1549 rebellions, has been intensely studied by historians of the period. However, most monographs of the rebellions pinpoint the enclosure commissions or Edward Seymour’s inability to govern effectively as the reasons behind the riots. What is ignored is the intimate relationship between the eastern rebels’ language in their petitions and the rhetoric employed in evangelical propaganda from Edward’s accession in January 1547 to the outbreak of the rebellions in May 1549. My research in Edwardian propaganda during Somerset’s protectorate reveals a dialogue established between evangelicals and Catholics concerning doctrine …

A Systematic Study Of Xylella Fastidiosa Strains Isolated From Pecan, Grapevine, Oleander, And Sycamore In Louisiana, Rebecca Ann Melanson Jan 2011

A Systematic Study Of Xylella Fastidiosa Strains Isolated From Pecan, Grapevine, Oleander, And Sycamore In Louisiana, Rebecca Ann Melanson

LSU Master's Theses

Xylella fastidiosa causes disease in a number of economically important crops and landscape shrubs and trees including grapevine, citrus, oleander, and sycamore. In pecan, X. fastidiosa causes pecan bacterial leaf scorch (PBLS), which leads to defoliation and reduces nut yield. No economically effective treatments are available for PBLS. In order to improve PBLS management practices, it is necessary to determine the subspecies of X. fastidiosa strains that infect pecan so potential sources of inoculum can be identified. Multiprimer PCR and phylogenetic analyses using nucleotide sequence data from the 16S-23S rDNA intergenic transcribed spacer (ITS) region and pglA consistently identified strains …

Using X-Ray Computed Tomography To Quantify Damage Of Hot-Mix Asphalt In The Dynamic Complex Modulus And Flow Number Tests, Hao Ying Jan 2011

Using X-Ray Computed Tomography To Quantify Damage Of Hot-Mix Asphalt In The Dynamic Complex Modulus And Flow Number Tests, Hao Ying

LSU Master's Theses

The dynamic modulus test is conducted based on the assumption that no damage is induced during the testing process and that measurements are conducted within the linear viscoelastic region. In addition, significant damage is expected to occur during the flow number test process. While these assumptions are well-defined, the levels of damage taking place during these tests have not been quantified. The objectives of this study were to quantify the levels of damage in the dynamic complex modulus and flow number tests using x-ray computed tomography (CT) and to characterize the microstructural properties of asphalt mixtures under loading. Four Superpave …

Numerical Studies Of Flow In Porous Media Using An Unstructured Approach, Nathan Matthew Lane Jan 2011

Numerical Studies Of Flow In Porous Media Using An Unstructured Approach, Nathan Matthew Lane

LSU Doctoral Dissertations

Flow and transport in porous media is relevant to many areas of engineering and science including groundwater hydrology and the recovery of oil and gas. Porous materials are characterized by the unique shape and connectivity of the internal void structures which give rise to a large range in macroscopic transport properties. Historically an inability to accurately describe the internal pore-structure has prevented detailed study of the role of pore structure on transport. In recent decades however, the combination of high resolution imaging technologies with computational modeling has seen the development of fundamental pore-scale techniques for studying flow in porous media. …

Hear (No) Evil, See (No) Evil, Speak (No) Evil: Artistic Representations Of Argentina's "Dirty War", Juliana Theresa Reineman

LSU Doctoral Dissertations

My dissertation utilizes an interdisciplinary approach to analyze Argentina’s “Dirty War; in it, I argue that our view of the Other is the key to not repeating the past. Literature has long been accepted as a resource for understanding culture; this dissertation moves beyond literature, and includes photography, art, and film to demonstrate how artists have represented and responded to this period of political oppression. Adopting a psychoanalytic approach for my research, I begin with a literary analysis of multiple texts which exhibit features of what Anne Whitehead calls “trauma fiction,” texts in which the narrative voice displays the repetition …

Genome-Wide Detection Of Novel Regulatory Rnas In E. Coli, Rahul Raghavan, Eduardo Groisman, Howard Ochman Jan 2011

Genome-Wide Detection Of Novel Regulatory Rnas In E. Coli, Rahul Raghavan, Eduardo Groisman, Howard Ochman

Biology Faculty Publications and Presentations

The intergenic regions in bacterial genomes can contain regulatory leader sequences and small RNAs (sRNAs), which both serve to modulate gene expression. Computational analyses have predicted the presence of hundreds of these noncoding regulatory RNAs in Escherichia coli; however, only about 80 have been experimentally validated. By applying a deep-sequencing approach, we detected and quantified the vast majority of the previously validated regulatory elements and identified 10 new sRNAs and nine new regulatory leader sequences in the intergenic regions of E. coli. Half of the newly discovered sRNAs displayed enhanced stability in the presence of the RNA-binding protein …

Analytical Design Method For Cold Production Of Heavy Oil With Bottom Water Using Bilateral Sink Wells, Wenting Qin Jan 2011

Analytical Design Method For Cold Production Of Heavy Oil With Bottom Water Using Bilateral Sink Wells, Wenting Qin

LSU Doctoral Dissertations

Few heavy oil reservoirs with strong bottom water drives have been developed successfully because of severe water coning. Water coning tends to cause low ultimate recovery, low well productivity, and high water production. Although thermal and gravity-assisted methods might improve recovery in oil reservoirs, such methods are widely perceived as either economically unfavorable or technologically infeasible. This study proposes a new, cold production technique, called Bilateral Water Sink (BWS), to meet those challenges. The BWS method suppresses water cresting by producing oil and water simultaneously from separate, horizontal wells completed in the oil and water zones; the oil and water …

Expression, Identification, And Bioactivity Of Recombinant Human Erythropoietin From Lmh/2a (Leghorn Male Hepatoma)Cell Line, Amanda Cecile Broussard

LSU Master's Theses

Erythropoietin (EPO) is the main cytokine regulator for red blood-cell production in the human by binding to erythropoietin receptors to promote erythroid proliferation, survival and differentiation. Administration of recombinant human EPO (rhEPO) as a therapeutic has been shown to improve renal and non-renal anemia and this success has led to a high medical global demand. Chinese hamster ovary (CHO) cells, yeast, and bacteria have been used to produce rhEPO but nevertheless there is still a need for a low-cost and high quality expression system for rhEPO. LMH/2A cells, as an alternative model, were transfected with the codon optimized human EPO …

Photochemical Reaction Products Of Polycyclic Aromatic Hydrocarbons Adsorbed At An Air-Water Interface, Franz Stefan Ehrenhauser Jan 2011

Photochemical Reaction Products Of Polycyclic Aromatic Hydrocarbons Adsorbed At An Air-Water Interface, Franz Stefan Ehrenhauser

LSU Doctoral Dissertations

Polycyclic aromatic hydrocarbons (PAH) are ubiquitous pollutants resulting from incomplete combustion and hence normally unavoidable. The kinetic aspects of the environmental degradation process have received considerable attention; however, not much is known about the degradation products themselves. Aqueous solutions of naphthalene, acenaphthene, 9H-fluorene, phenanthrene and pyrene were subjected to UVB light in a bulk-phase and a thin-film reactor to assess the identity of the formed photodegradation products. To aide in the challenging analysis of these mixtures, a novel analytical technique based on high performance liquid chromatography (HPLC) coupled to UV diode-array detection and dopant-assisted atmospheric pressure photoionization mass …

Inside Out, Kathleen Ann Pheney Jan 2011

Inside Out, Kathleen Ann Pheney

LSU Master's Theses

Because I process my external world internally, I often think of my mind as a vessel-housing my internal reality: fears, demons, curiosities, joys, sorrows, etc. My body of work is comprised of paintings and drawings that present surreal interpretations of these occupants as depicted through line, color, gesture and form and, as such, are true self-portraits in that they bring the “inside out.”

Layout-Based Substitution Tree Indexing And Retrieval For Mathematical Expressions, Matthew Schellenberg Jan 2011

Layout-Based Substitution Tree Indexing And Retrieval For Mathematical Expressions, Matthew Schellenberg

Theses

We introduce a new system for layout-based indexing and retrieval of mathematical expressions using substitution trees. Substitution trees can efficiently store and find hierarchically-structured data based on similarity. Previously Kolhase and Sucan applied substitution trees to indexing mathematical expressions in operator tree representation (Content MathML) and query-by-expression retrieval. In this investigation, we use substitution trees to index mathematical expressions in symbol layout tree representation (LaTeX) to group expressions based on the similarity of their symbols, symbol layout, sub-expressions and size. We describe our novel substitution tree indexing and retrieval algorithms and our many significant contributions to the behavior of these …
