Translating Exile In Panait Istrati's "Mes Departs", Samuel Beckett's "Fin De Partie" And Selected Poems By Paul Celan., Ina Alice Pfitzner
LSU Historical Dissertations and Theses
Translation and exile are two phenomena that marked life in the twentieth century, especially in Europe, and have therefore left their traces in French literature as well. Translation from one language to another is a heightened form of the translation process inherent in any writing. Exile in a foreign country, linguistic exile, is an aggravated form of the exile every human being experiences at some point. Parting from Lucian Blaga's concept of "mioritic space," which is based on the Romanian myth of Mioritza, as well as Walter Benjamin's essay "Die Aufgabe des Ubersetzers" [The Task of the Translator], this study …
Optimization Of Agrobacterium-Mediated Genetic Transformation Of Soybean Using Glufosinate As A Selective Agent., Shaomian Yao
Optimization Of Agrobacterium-Mediated Genetic Transformation Of Soybean Using Glufosinate As A Selective Agent., Shaomian Yao
LSU Historical Dissertations and Theses
Soybean [Glycine max (L.) Merr] is one of the most important oil crops. Genetic transformation techniques can provide new tools for soybean improvement. The production of transgenic soybean has been limited. This research integrated a modified soybean regeneration system into a transformation protocol to optimize the production of transgenic soybean. Soybean hypocotyls and cotyledonary nodes were cultured on Gamborg B5 medium containing thidiazuron (TDZ). TDZ at 0.16 muM was found superior to other concentrations for inducing multiple shoot formation. Explants isolated from seedlings germinated on medium containing 6-benzyl-aminopurine (BAP) greater than 7 muM produced more multiple shoots than when on …

The 37-question survey instrument used in the study included 15 demographic questions and one-open ended question requesting respondents to provide suggestions that could be used to help other students. In addition, 21 perception statements were asked loan recipients. This study found that …
Treatment Outcome Of Childhood Obesity: The Effect Of Children's Psychological Distress And Problematic Behavior., Tana Louise Hope
Treatment Outcome Of Childhood Obesity: The Effect Of Children's Psychological Distress And Problematic Behavior., Tana Louise Hope
LSU Historical Dissertations and Theses
The number of children and adolescents effected by obesity has been increasing over the past 30 years. Current treatment of childhood obesity focuses primarily on increasing physical activity, modifying diet, providing nutritional education and teaching self-monitoring and stimulus control procedures. Although children have been shown to lose weight by participating in these treatment programs, the amount of weight children lose during treatment is often small, and long-term maintenance of weightloss continues to be challenging for many. Given the relatively weak outcome of childhood obesity treatment programs, research into factors that effect treatment outcome is needed. Psychological distress and problematic behavior …

Investigation Of Amphoteric Materials For Treatment Of Heavy Metals In Storm Water., Dingfang Liu
LSU Historical Dissertations and Theses
Urban storm water runoff mobilizes and transports significant loads of heavy metals. Promulgation of NPDES Phase II regulations has spurred development of Best Management Practices (BMPs) for in-situ control of heavy metals. In this study, Amphoteric materials such as manganese oxides and iron oxides on the various substrates including silica sands, polymeric beads and cementitious particles were investigated. Surface characterization results indicated that oxide coatings ranged from 20 to 200-mum in depth, and surface areas were significantly increased by greater than a factor of one thousand compared to uncoated media. Point of zero charge (PZC) for manganese oxide coated media …
Caught In The Middle: The Construction, Expression, And Transformation Of Identity Among Haitian Youth In Montreal., Earl Floyd Scooter Pegram
Caught In The Middle: The Construction, Expression, And Transformation Of Identity Among Haitian Youth In Montreal., Earl Floyd Scooter Pegram
LSU Historical Dissertations and Theses
This dissertation examines identity issues among Haitian youth in Montreal, Quebec (Canada). Because Haitians are the largest group of "visible minorities" in the province and are an integral part of the Quebec mosaic, the distinctive "sense of belonging" felt by youth in the Haitian community necessitates further inquiry into what connections they (Haitian youth) have with both the majority Quebecois culture and the minority Haitian immigrant culture of Montreal. Since Quebec is a Francophone society in a North America that is majority Anglophone, this linguistic and cultural confusion sometimes results in immigrant youth assuming multiple identities in order to "fit …

Epidemiology Of Salmonella In The Green Iguana (Iguana Iguana)., Mark Anthony Mitchell
LSU Historical Dissertations and Theses
The incidence of iguana-associated salmonellosis reported in humans during the 1990's is a public health concern. This research is the first attempt to describe the epidemiology of Salmonella in the green iguana. Seasonal prevalence of Salmonella in green iguanas and their environment were estimated at a commercial iguana farm in El Salvador. The prevalence of Salmonella was lower in adult iguanas (44%) than in yearlings (50%) (Odds ratio (OR): 0.77, 95% Confidence Intervals (CI): 0.6--0.96) and higher in male iguanas (50%) than females (41%) (OR: 1.5, 95% CI: 1.2--1.8). Salmonella recovery was lower in the fall (41%) sampling period than …
Analysis And Mathematical Modeling Of Autonomously Oscillating Yeast Cultures., Abdelqader M. Zamamiri
Analysis And Mathematical Modeling Of Autonomously Oscillating Yeast Cultures., Abdelqader M. Zamamiri
LSU Historical Dissertations and Theses
The conditions that precede the onset of autonomous oscillations in continuous yeast cultures were studied in three different types of experiments. It was found that the final state of the culture depends on the protocol used to start-up the reactor. Reaching the desired operating point by slow dilution rate changes gave rise to different final states, two oscillatory states and one steady state, depending on the rate of change in dilution rate. The multiplicity of stable states at a single operating point is not explained by current distributed models and points towards a segregated mechanism of these oscillations. The ability …

Analysis Of Near-Infrared Dye-Labeled Sanger Sequencing Fragments With Gel Electrophoresis Using The Time-Resolved Flourescence Lifetime Indentification Methods, Suzanne Jeanel Lassiter
LSU Doctoral Dissertations
The research presented in this dissertation involves the identification of sequencing fragments with time-resolved methods. For this application, near-infrared heavy-atom tricarbocyanine dyes were developed in our laboratory, which can be excited with a single laser and emission collected using a single detection channel. The dyes have four spectroscopically unique, but relatively short lifetimes that can be altered by the intramolecular heavy-atom they contain. The work described here involves the optimization of dye-primer chemistry for preparing Sanger sequencing reactions for longer reads and the optimization of the separation matrix for capillary gel electrophoresis that produces favorable statistical analysis of the aforementioned …
Grave Matter: Contestations In Actress Burial, Christine Courtland Mather
Grave Matter: Contestations In Actress Burial, Christine Courtland Mather
LSU Doctoral Dissertations
Death disrupts. The social space accorded to rituals of death and memorialization differs from all other spaces. Actresses disturb. Society contests, determines, and enacts the burial of an actress as her final performance. This study explores the actress burial as a site of meaning. Contestations over the fate of the actress body reveal power structures and the motivations of cultural institutions. This study highlights four actresses—Lecouvreur, Oldfield, Bernhardt, and Duse—whose burials cover a wide range of circumstances. Each chapter gives the relevant biographical information for the actress and the social background for the cultural contestation over the actress body. Traditional …

Effects Of Nitric Oxide Synthase Inhibitors On Equine And Bovine Follicular Dynamics And Steroidogenesis., Carlos Roberto Fontes Pinto
LSU Historical Dissertations and Theses
Current scientific literature has shown that: (1) NO is a pro-ovulatory agent and inhibition of its production inhibits ovulation, and (2) NO has strong antisteroidogenic activity, especially on estradiol (E2) production by granulosa cells. The experiments described in this dissertation were designed to answer the following questions involving effects of NO on ovarian physiology: (1) is the inhibitory effect of nitric oxide synthase (NOS) inhibitors on ovulation irreversible (follicular atresia) or temporary (delayed ovulation)? and (2) what is the relationship between NO and hCG-induced preovulatory luteinization? Accordingly, cycling mares were subjected to treatment with NOS inhibitors (L-NAME or aminoguanidine) during …

This study explores how advertising and company promotion may be used to address social issues. In particular, I examine how the clothing company United Colors of Benetton attempted to position itself within the AIDS crisis. Specifically, this study investigates through case studies how the Benetton Group used activist advertising and company promotion to bring about social change concerning AIDS-related issues. I also attempt to account for the controversy that the promotion elicited through establishing the anomalous status of the company's promotion within traditional advertising efforts. The study begins with information concerning the AIDS crisis and AIDS activism and then moves …
Home And Classroom Learning Environment Correlates Of Academic Self -Efficacy In Middle School Mathematics., Thaddeus Theodore Claiborne
Home And Classroom Learning Environment Correlates Of Academic Self -Efficacy In Middle School Mathematics., Thaddeus Theodore Claiborne
LSU Historical Dissertations and Theses
This study investigated the relationship between home and classroom learning environment characteristics and middle school students' self-efficacy beliefs about mathematics. Specifically, the study examined linkages between sources of efficacy in the home and classroom learning environments and the strength of students' self-efficacy beliefs in mathematics. Social cognitive theory includes self-efficacy beliefs as a major source of human agency and functioning (Bandura, 1997). Enactive mastery experiences, vicarious learning (modeling), verbal persuasion, and physiological/affective states (emotional arousal) are four sources of human efficacy. While numerous studies have been completed linking self-efficacy to learning and achievement (Pajares, 1996b), no studies within schools were …

Electronic Communication Channels In Franchise Organizations., Michael Hebert Dickey
LSU Historical Dissertations and Theses
The virtual organization has emerged as a result of the availability of information technology. One business model well suited to the virtual form is franchising. Since the success of franchise organizations is highly dependent on communication effectiveness, these organizations are beginning to adopt technology---namely, private corporate networks called intranets and extranets---to support electronic communication. This research study examines the effects of electronic communication channels on communication patterns within franchise organizations. First, the study addresses how electronic communication channels affect communication frequency within the franchise organization. Second, the effect of electronic communication channels on strategic outcomes, specifically, innovation, franchisee satisfaction, and …
Design, Fabrication, And Testing Of Cross Flow Micro Heat Exchangers., Chad Randall Harris
Design, Fabrication, And Testing Of Cross Flow Micro Heat Exchangers., Chad Randall Harris
LSU Historical Dissertations and Theses
Cross flow micro heat exchangers were designed to maximize heat transfer from a liquid (water) to a gas (air) for a given frontal area while holding the pressure drop across the heat exchanger of each fluid to values characteristic of conventional scale heat exchangers (car radiators). The cross flow micro heat exchanger design is unique since it produces a very high rate of heat transfer/volume between dissimilar fluids with low fluid pressure drops. Predicted performance for two types of cross flow micro heat exchangers is compared to each other and to current innovative car radiators. Although the cross flow micro …
From The Shadow Of Reagan: George Bush And The End Of The Cold War., Christopher Alan Maynard
From The Shadow Of Reagan: George Bush And The End Of The Cold War., Christopher Alan Maynard
LSU Historical Dissertations and Theses
George Bush entered the presidency constantly compared and contrasted with his predecessor, Ronald Reagan. Lacking Reagan's eloquence and adept use of the media, Bush was lambasted by the press as Reagan's "lapdog" and labeled a "wimp." The press pushed Bush to establish themes to match policy goals and to use the bully pulpit to lead the national debate on issues. His refusal prompted journalists to characterize the Bush presidency as lacking an agenda. Reagan's success with the media and Bush's failure have produced a misconception about the successes and failures of each president's policies. Thus, the period usually is referred …
Modified Mesoporous Silicates For Metal Adsorption., Allison Majorie Naquin
Modified Mesoporous Silicates For Metal Adsorption., Allison Majorie Naquin
LSU Historical Dissertations and Theses
Mesoporous silica materials, commonly called Hexagonal Mesoporous Sieves (HMS), are used to adsorb copper, lead, and mercury from aqueous solution. To increase metal adsorption, organic ligands with high metal affinity are grafted to the surface of the HMS materials. Three ligands were used in this research: 3-mercaptopropyltrimethoxysilane (MP), 3-aminopropyltrimethoxysilane (AM), and p-(aminoethylaminomethyl)phenethyltrimethoxysilane (AB). The physical properties of HMS include large surface area and an ordered system of pores. These properties are believed to increase the extraction capabilities of the material by increasing the molar content of the chelating ligand and by making the ligand more accessible. The purpose of this …

The Geometry Of Electronically -Excited States: Vibronic Intensity Distributions And Bond Length Changes., Dorothy Marie Wood
The Geometry Of Electronically -Excited States: Vibronic Intensity Distributions And Bond Length Changes., Dorothy Marie Wood
LSU Historical Dissertations and Theses
An exact power series expression has been obtained for the Franck-Condon integral (FCI) in the harmonic approximation. This expression is a function of a parameter Delta where Delta → 0 as the frequencies of vibration in the two combining electronic states approach equality. These two characteristics, that of a power series in Delta and the fact that Delta → 0 in certain situations, permit truncation of various functions involving FCI's. Such truncation was performed for the ratio S2v'0'' /S2v'-1 0'' , where the S2v'v'' are the FCI's, and the subscripts, in the usual notation, denote the vibrational quantum numbers in …
