Metamorphoses Of The Pygmalion Myth In French Literature 1771 – 1886, Carrie L. O'Connor
Metamorphoses Of The Pygmalion Myth In French Literature 1771 – 1886, Carrie L. O'Connor
LSU Doctoral Dissertations
Writers have long explored and attempted to portray the visual artist’s challenge of creating the ideal in the real world through art. My thesis asserts that the Pygmalion myth, originally told in written form in Ovid’s 8 A.D. Metamorphoses, is the quintessential model to explore the changing, and sometimes problematic, relationships between the artist, the creation, and the creative process. The three main characters in the Pygmalion myth – the sculptor, the sculpture, and the divine intervention – each appear, albeit in different manifestations, in its later adaptations. Throughout the late eighteenth and nineteenth centuries in French literature, authors explored …

Calibration And Categorization Of Plant Available Silicon In Louisiana Soils, Tapasya Babu
LSU Doctoral Dissertations
A survey was conducted to document the silicon (Si) content of soils from 27 (selected) agrarian parishes of Louisiana using different extraction procedures. For 0.01 M calcium chloride (CaCl©ü) extraction procedure, all surveyed soils (n=212) fell below 56 mg Si kg⁻©ö. For five of the procedures, about 50% of surveyed soils in Louisiana had Si level below the critical Si level that thus far established in other regions. Calcium silicate slag and wollastonite were compared through chemical extractions after laboratory incubation with six different soil types, and then an assessment of quantity of monosilicic acid (H©þSiO©þ) sorbed and the quantity …
Examining Electronic Medical Records System Adoption And Implications For Emergency Medicine Practice And Providers, Barbara Cook Overton
Examining Electronic Medical Records System Adoption And Implications For Emergency Medicine Practice And Providers, Barbara Cook Overton
LSU Doctoral Dissertations
This ethnographic research study documented the use and effects of an electronic medical records system (EMR) by healthcare providers working in a community hospital-based emergency room. Using data collected from participant observation, in-depth interviews, questionnaires, and hospital documents, the research findings suggest EMRs impinge providers’ agency, alter emergency room systems, affect communication patterns among providers, and exacerbate structurational divergence (SD) conditions. Findings suggest that providers’ attempts to regain lost agency tips the SD-nexus into an SD-cycle, characterized by negative communication spirals between providers. The discussion chapter examines the impact of EMRs on emergency room structures, system reproduction, providers’ workflow and …
Thiol-Ene Scaffolds As Synthetic Augments And Silicate Ceramics As Osteogenic Components For Bone Tissue Engineering Applications, Cong Chen
LSU Doctoral Dissertations
Bone tissue engineering approaches using polymer/ceramic composites show promise as effective biocompatible, absorbable, and osteoinductive materials. A novel class of in situ polymerizing thiol-acrylate based copolymers synthesized via an amine-catalyzed Michael addition was studied for its potential to be used in bone defect repair. Both pentaerythritol triacrylate-co-trimethylolpropane tris(3-mercaptopropionate) (PETA-co-TMPTMP) and PETA-co-TMPTMP with hydroxyapatite composites were fabricated in solid cast and foamed forms. These materials were characterized chemically and mechanically followed by an in vitro evaluation of the biocompatibility and chemical stability in conjunction with human adipose-derived mesenchymal pluripotent stem cells (hASC). The solid PETA-co-TMPTMP with and without hydroxyapatite (HA) exhibited …
Regulatory Impacts Of Assembled Pol Iii Complexes On Neighboring Pol Ii Transcribed Genes In Saccharomyces Cerevisiae, Qing Wang
LSU Doctoral Dissertations
RNA polymerase III (Pol III) transcribes tRNAs as well as other small non-coding RNAs. tRNA genes contain internal promoter sequences (A- and B-boxes) which can be specifically recognized and bound by TFIIIC. Binding of TFIIIC facilitates TFIIIB recruitment, which in turn targets Pol III to be recruited and initiate transcription. In addition to typical tRNA genes, there are other chromosomal regions, referred as extra-TFIIIC (ETC) sites, that are only bound by TFIIIC. Apart from transcription of genes, both complete and partially assembled Pol III complexes perform extra-transcriptional functions such as influencing nearby Pol II transcription, displacement of nearby nucleosomes, as …
Articulating Situated Knowledge And Standpoints In Our Responses To Contemporary Street Fiction: A Book Club Case Study With African American Women, Yvette Rachele Hyde
Articulating Situated Knowledge And Standpoints In Our Responses To Contemporary Street Fiction: A Book Club Case Study With African American Women, Yvette Rachele Hyde
LSU Doctoral Dissertations
Contemporary street fiction is a form of literature that has been growing in popularity since the 1990s. Such novels are set in contemporary urban contexts and present the experiences of historically oppressed groups. Sold in venues such as independent bookstores, the Internet, barbershops, beauty salons, flea markets, street vendors, and churches (Hill, Pérez, & Irby, 2008; McClellan, 2011), this genre is especially popular among African American females. Because much of the scholarship concerning engagement with contemporary street fiction focuses on improving school literacy skills, the purpose of this study was to investigate readers’ responses in a book club held at …
Stress Tolerance Enhancement Of Rice By Genetic Manipulation Of A Bhlh-Myc2 Transcription Factor, Luis Eduardo Sanchez Timm
Stress Tolerance Enhancement Of Rice By Genetic Manipulation Of A Bhlh-Myc2 Transcription Factor, Luis Eduardo Sanchez Timm
LSU Doctoral Dissertations
Rice yield is adversely affected by various abiotic and biotic stresses. Jasmonic acid (JA) signaling has been implicated in stress response of plants. The nuclear localized basic helix loop helix (bHLH) Myc2 transcription factor is known to be a master regulator of genes involved in the response of the JA-mediated signaling pathway during stress and plant development. Myc2 is also induced by wounding and mechanical damage, and is associated with resistance against herbivore insects. In order to understand the mode of action of Myc2 in stress response of rice, overexpresser (OE) and knock-down (KD) mutants for OsMyc2 were generated in …
Hybrid Electronic Materials: Characterization And Thin-Film Deposition, Kalyan Chakravarthy Kanakamedala
Hybrid Electronic Materials: Characterization And Thin-Film Deposition, Kalyan Chakravarthy Kanakamedala
LSU Doctoral Dissertations
Hybrid Electronic Materials (HEMs), as defined for this dissertation, are combinations of organic and inorganic materials as may be used to fabricate active device components in “beyond the transistor” electronics. However, the use of organics is often limited by issues such as thermal stability, compatibility with traditional (semiconductor) materials, and current processing technology. Thus, we began our exploration of HEMs with a “new” class of materials called GUMBOS (Group of Uniform Materials Based on Organic Salts) as derived from ionic liquids. For this first segment of our work, we investigated selected species of GUMBOS and nanoGUMBOS via their current-voltage characteristics, …
Laboratory Experimental Demonstration Of The Effect Of Oceanic Whitecaps In The Transport Of Oil And Dispersant Components To The Atmosphere, Paria Avij
LSU Doctoral Dissertations
During the DWH oil spill, vast quantities of crude oil were released into the sea-surface environment of the Gulf of Mexico. There has been ample research focused on the transport of oil into the different environmental sections. Evaporation has been considered to be the only transport pathway of oil spill matter into the atmosphere. However, the aerosolization of oil and dispersant via bursting bubbles as they occur in whitecaps and breaking waves has not been considered in the oil and dispersant budget calculation. This transport vector is significant as it is the dominant source of particulate matter production in the …
Three Year Assessment Of Nearshore Crude Oil Contamination In The Gulf Of Mexico Using Gulf Menhaden (Brevoortia Patronus) As An Indicator Species: Menhaden Watch, Gregory Michael Olson
Three Year Assessment Of Nearshore Crude Oil Contamination In The Gulf Of Mexico Using Gulf Menhaden (Brevoortia Patronus) As An Indicator Species: Menhaden Watch, Gregory Michael Olson
LSU Doctoral Dissertations
Approximately 4.9 million barrels of crude oil along with natural gas were released into the Gulf of Mexico (GoM) from April to July 2010 (Deepwater Horizon, DWH, spill). Impacts of this magnitude seldom occur in the GoM (Ixtoc I was the last spill close to this magnitude occurring in 1979), and one cannot predict when they will happen. Major constituents of concern found in crude oil are Polycyclic Aromatic Hydrocarbons (PAHs), which often have low volatility that allows for prolonged existence in the environment. PAHs are compounds of concern according to the United States Environmental Protection Agency (USEPA), with one …

Mechanisms Controlling Stem Cell Differentiation, Tran Doan Ngoc Tran
Mechanisms Controlling Stem Cell Differentiation, Tran Doan Ngoc Tran
LSU Doctoral Dissertations
Mesenchymal stem cells are multipotent cells that can differentiate into many cell types. However, the molecular mechanism controlling this process remains unclear. We utilized rat dental follicle stem cells (rDFSCs) and human adipose derived stem cells (hASCs) to study the mechanisms controlling osteogenesis and adipogenesis. Elevations in the intracellular Ca2+ concentration are a phenomenon commonly observed during stem cell differentiation but cease after the process is complete. The Transient Receptor Potential Melastatin 4 (TRPM4) is an ion channel that controls Ca2+ signals in excitable and non-excitable cells. However, there are no studies on TRPM4 in stem cells. In another study, …

Bacterial Xanthine Dehydrogenase Regulators, Smitha Sivapragasam
LSU Doctoral Dissertations
Bacteria are resilient organisms that tend to evolve rapidly in order to acquire abilities to survive in a constantly changing environment. Transcriptional regulators play a vital role in regulating the function of various essential proteins of the cell. The gene encoding Xanthine Dehydrogenase Regulator (XdhR), a transcriptional regulator, is divergently oriented to the gene cluster (xdhABC) encoding Xanthine Dehydrogenase (Xdh) protein in Streptomyces coelicolor, Agrobacterium tumefaciens and Ralstonia solanacearum. Xdh participates in purine salvage pathway in converting adenine to guanine. My research here is aimed at identifying the novel function of Xdh and XdhR in the above mentioned bacteria. XdhR …
Investigating The Photorecombination Dynamics In Molecular High-Harmonic Spectra, Benjamin Parker Wilson
Investigating The Photorecombination Dynamics In Molecular High-Harmonic Spectra, Benjamin Parker Wilson
LSU Doctoral Dissertations
The work presented in this dissertation will relate the photorecombination dynamics to photoionization dynamics in SF6 utilizing the self-probing mechanism, high harmonic generation (HHG). This work specifically aims to establish parameters for which the comparison is applicable and the macroscopic complications inherent in HHG do not interfere with the extraction of dynamic information. The first part of this work established the macroscopic experimental apparatus necessary for consistent spectroscopic observation. It is shown that using a gas jet that is an order of magnitude shorter than the Rayleigh length of the driving laser results in more consistent harmonic spatial profiles and …

Pathogenic Enteric Viruses In Louisiana Oysters And Environmental Waters, Naim Montazeri Djouybari
LSU Doctoral Dissertations
Norovirus (NoV) and pathogenic enteroviruses are the major causes of gastroenteritis in humans worldwide, and are usually transmitted through direct or indirect exposure to raw or partially treated sewage. Filter-feeding shellfish concentrate virus particles from the water and transmit them to humans. The occurrence of norovirus GI and GII and fecal indicators in Louisiana eastern oysters (Crassostrea virginica) and harvest water were investigated on a biweekly basis for almost one year. Only one oyster sample was positive for NoV GII at 3.5 log10 genomic copies/g digestive tissues. A stool specimen obtained from an infected individual associated with a norovirus outbreak …
Recovery From Exercise: The Influences Of Supplementation And Rest Interval, Ryan Miskowiec
Recovery From Exercise: The Influences Of Supplementation And Rest Interval, Ryan Miskowiec
LSU Doctoral Dissertations
Recovery from exercise is immensely important and under studied. The experiments conducted throughout this research have focused on testing the effects of rest interval during resistance exercise and the efficacy of acetic acid feeding on recovery rate. To elucidate the relationship between rest interval and recovery energy expenditure two experiments were undertaken. These experiments were designed to alter only rest interval while maintaining work intensity and volume. No difference in the total energy expenditure during the short phase of recovery (first hour) was found, but energy expenditure during the prolonged phase (days post exercise) was minorly increased by lowering rest …
Product Parameters Optimization For Double Purge Of C-Magma Integrated With Conventional Three-Boiling Crystallization Scheme To Improve Raw Sugar Whole Color, Luz Stella Polanco
Product Parameters Optimization For Double Purge Of C-Magma Integrated With Conventional Three-Boiling Crystallization Scheme To Improve Raw Sugar Whole Color, Luz Stella Polanco
LSU Doctoral Dissertations
Efficient crystallization in raw sugar production is the result of a combination of factors and responses that meet specific criteria. Matching a sugar quality standard, maximizing sugar yield, maximizing crystallization equipment capacity and minimizing heat requirement are all necessary optimization criteria. A double centrifugation or purge of C-magma is intended to improve raw sugar whole color by the reduction of color recirculation with the sugar crystal. Combining a three boiling crystallization scheme with a second centrifugation after the last crystallization stage required optimizing the input/output product parameters (purities) and the location of the liquid recycle component (double purge molasses) for …
Civic Community, Structural Disadvantage, And Suicide: An Ecological Analysis Of Middle-Age Non-Hispanic White Male Suicide Across The Rural-Urban Continuum, Kayla R. Fontenot
Civic Community, Structural Disadvantage, And Suicide: An Ecological Analysis Of Middle-Age Non-Hispanic White Male Suicide Across The Rural-Urban Continuum, Kayla R. Fontenot
LSU Doctoral Dissertations
This dissertation is a county-level sociological examination of middle-age (35-64) non-Hispanic white male suicides. Although an extensive amount of literature exists on ecological suicide, studies have largely ignored the correlates of suicide among this population group because this stage of the life course has historically demonstrated relatively low and stable rates of suicide. However, suicide rates among middle-age adults have increased dramatically over the last decade, calling for an examination of the correlates of suicide specific to this group. Moreover, the extant suicide literature has largely ignored the possibility of a structural disadvantage-suicide link, as well as the influence of …

In the first phase, the shroud heat transfer behavior and the effectiveness of shroud cooling under the conditions of rotation is undertaken in a single stage turbine at a design rotation speed of 550 rpm, at off-design speeds and for varying …
Paradoxical Agency: The Ethics Of Women's Rhetoric In Shakespeare's Rome, Catherine Riley Godbold
Paradoxical Agency: The Ethics Of Women's Rhetoric In Shakespeare's Rome, Catherine Riley Godbold
LSU Doctoral Dissertations
In this project, I address the problems of ethics and agency for women’s speech in Shakepseare’s Roman plays—Julius Caesar, Antony and Cleopatra, Titus Andronicus, and Coriolanus—and the narrative poem The Rape of Lucrece. Regardless of their rhetorical skill, virtue, or agency, it seems that the Roman women in these works are doomed to fail: either their lives become unlivable or they lose the people most important to them. This prompts the project’s initiating question: why do Shakespeare’s Roman women speak if their words have no long-term effect? For these characters, rhetorical success in Shakespeare’s Rome is dependent upon a particular …

Communicating Sustainability With Visuals: Issue Perception And Issue Engagement, Zeynep Melis Altinay
LSU Doctoral Dissertations
Today the list of environmental disasters threatening lives and natural resources has expanded to include many causes. Even though sustainable solutions have never been so urgent, public still issues low priority to many of these serious threats. Many impacts of environmental deprivation, such as coastal land loss, are invisible to the untrained eye, causing individuals to distance themselves psychologically from the risks. The slow pace of environmental degradation constitutes one of the biggest challenges in sustainability communication. The success of sustainable development will require the public to undergo a significant shift in thinking about environmental issues. This dissertation systemically investigates …
