The Body Morph Assessment Version 2.0 (Bma 2.0): A Psychometric Study, Tiffany M. Stewart
The Body Morph Assessment Version 2.0 (Bma 2.0): A Psychometric Study, Tiffany M. Stewart
LSU Doctoral Dissertations
A computerized procedure for assessing body image, called the Body Morph Assessment Version 2.0 (BMA 2.0), was developed to serve as reliable and valid measure of body image. The BMA 2.0 is an extention of an earlier prototype called the Body Morph Assessment (BMA; Stewart, Williamson, Smeets, & Greenway, 2000). Although flexible in its uses, the BMA 2.0 targets the measurement of body image in people ranging in body size from very thin to very obese. The BMA was evaluated in terms of its psychometric characteristics. A sample of 217 subjects, composed of four distinct groups classified by gender and …
The Post-Translational Methylation Of Arginine In The Glycine Arginine Rich Region Of Cho Nucleoin, Gregory James Pellar
The Post-Translational Methylation Of Arginine In The Glycine Arginine Rich Region Of Cho Nucleoin, Gregory James Pellar
LSU Doctoral Dissertations
Nucleolin is a nucleolar protein important for ribosome biogenesis. Nucleolin contains a conserved glycine arginine rich (GAR) domain near its carboxy terminus. GAR domains are defined by repeating tri-peptide, (arginine -glycine-glycine (RGG)) motifs. The arginine in the RGG motif is post-translationally modified by dimethylation on one of the two guanido nitrogens. Although arginine methylation was identified over 30 years ago, the function of this modification remains unknown. The GAR domain of nucleolin is important for nucleic acid binding and for nucleolar localization of nucleolin. This dissertation describes investigates possible in vivo interactions between nucleolin and other nucleolar proteins involved in …
Effects Of Several Abiotic And Biotic Factors And Plant Hormones On Growth, Morophology, And Camptothecin Accumulation In Camptotheca Acuminata Seedlings, Zhanhai Li
LSU Doctoral Dissertations
This dissertation seeks to explore the effects of abiotic factors [nitrogen (N), sodium chloride (NaCl), and ultraviolet (UV) light], biotic factor [acetylsalicylic acid (ASA)], and plant hormones [benzyl adenine (BA) and naphthalene acetic acid (NAA)] on growth, morphology, and secondary metabolite, camptothecin (CPT, an anti-cancer compound) accumulation in Camptotheca acuminata. Five experiments were conducted with C. acuminata seedlings in a hydroponic system with commercial media and fluorescent lights and at 22-26 °C to investigate the effects of these five factors on height, weight, leaf number, leaf length, root to shoot ratio (RSR), specific leaf weight (SLW), CPT concentrations in leaves …
Impact Of Subject Related Factors And Position Of Flight Control Stick On Acquisition Of Simulated Flying Skills Using A Flight Simulator, Bo-Keun Cho
LSU Doctoral Dissertations
Increasing demand on aviation industry calls for more pilots. Thus, pilot training systems and pilot-candidate screening systems are essential for civil and military flying training institutes. Before actual flight training, it is not easy to determine whether a flight trainee will be successful in the training. Due to the high cost of actual flight training, it would be better if there were low cost methods for screening and training candidates prior to the actual flight training. This study intended to determine if subject related factors and flight control stick position have an impact on acquisition of simulated flying skills using …
The Greek Sophists : Teachers Of Virtue, David Dwyer Corey
The Greek Sophists : Teachers Of Virtue, David Dwyer Corey
LSU Doctoral Dissertations
This dissertation is a study of the Greek sophists as teachers of aretê (virtue or human excellence) and a study of the conflict between sophistic and Socratic political values as portrayed in the dialogues of Plato. The first section offers a new definition of the term "sophist" based on ancient sources and attempts to present as clear a picture as is historically possible of the sophists' activities. The second section examines and evaluates Plato's criticisms of the sophists drawing attention especially to the dependence of certain criticisms upon a questionable set of epistemological assumptions about the role of knowledge in …
The Impact Of Institutional Stock Ownership On A Firm's Earnings Management Practice: An Empirical Investigation, Santanu Mitra
The Impact Of Institutional Stock Ownership On A Firm's Earnings Management Practice: An Empirical Investigation, Santanu Mitra
LSU Doctoral Dissertations
This study examines whether institutional investor shareholdings inhibit firm managers from engaging in earnings management practice. It investigates the empirical association between discretion/flexibility available to managers in managing abnormal non-cash working capital accruals and institutional stock ownership for a sample of 386 New York Stock Exchange firms over a period of 8 years, from 1991 through 1998. The differential institutional influence on the level of accrual management of firms having different information environment, S&P 500 versus non S&P 500, is also examined to see whether the difference in information environment of these two sets of firms has any effect on …
Pay Satisfaction Consequences : Development And Test Of A Theoretical Model, Larry Hugh Faulk Ii
Pay Satisfaction Consequences : Development And Test Of A Theoretical Model, Larry Hugh Faulk Ii
LSU Doctoral Dissertations
The considerable research examining pay satisfaction over the past thirty years has focused on antecedents and the conceptualization of the construct. Notably little attention has been given to pay satisfaction consequences. This dissertation incorporates organizational justice literature to develop a model of pay satisfaction consequences and then shows the effect of pay satisfaction on job performance, turnover intentions, organizational commitment, and other variables. Two typologies are created to explain the relationship between pay satisfaction dimensions and consequences. One typology classifies the dimensions of pay satisfaction according to their form and what type of exchange is created with the organization. The …
Peroxynitrite-Mediated Oxidations: Nitration And Nitrosation, Rachel Bolzan
Peroxynitrite-Mediated Oxidations: Nitration And Nitrosation, Rachel Bolzan
LSU Doctoral Dissertations
Using a direct ultraviolet second-derivative spectroscopy method, three peroxynitrite preparative methods were investigated for the nitrite and nitrate present either as impurities or produced during peroxynitrite decomposition: (I) ozonation of azide, reaction of hydrogen peroxide with (II) isoamyl nitrite and (III) nitrous acid. The oxidation of morpholine by peroxynitrite in the presence and absence of added carbonate gives N-nitromorpholine and N-nitrosomorpholine. Nitration and nitrosation of morpholine are catalyzed by low levels of CO2; however, excess CO2 dramatically reduces the yields of nitrosation but not nitration, and the combined yields of the products are about the same under …
The Combined Effects Of Salinity And Sulfide On The Growth And Physiology Of The Freshwater Marsh Plant Pancium Hemitomon J.A. Schultes, James Wesley Pahl
The Combined Effects Of Salinity And Sulfide On The Growth And Physiology Of The Freshwater Marsh Plant Pancium Hemitomon J.A. Schultes, James Wesley Pahl
LSU Doctoral Dissertations
Vegetative response to saltwater intrusion into coastal freshwater wetlands is governed by the combined effects of increased salinity and porewater sulfide concentrations. I conducted a series of experiments to address the primary hypothesis that growth of Panicum hemitomon is adversely affected by an interaction between salinity and sulfide stresses associated with saltwater intrusion, and the mechanisms for decreased growth are alterations in the metabolic and morphological adaptations needed for a plant to survive in a flooded environment. I exposed marsh sods to a factorial treatment arrangement of three salinities (0, 2, and 4 ppt) and three porewater sulfide concentrations (0, …

Dynamic Modeling And Analysis Of Oscillatory Bioreactors, Yongchun Zhang
Dynamic Modeling And Analysis Of Oscillatory Bioreactors, Yongchun Zhang
LSU Doctoral Dissertations
Dynamic modeling of bioreactors is a challenging problem. The complexity of first principle models also make model validation and analysis very difficult and model-based controller design practically intractable. This thesis has focused on finding an effective tool for model dynamic analysis, construction of low-dimension model and simple and effective controller design. The validity of a biochemical reactor model often is evaluated by comparing transient responses to experimental data. Dynamic simulation can be rather inefficient and ineffective for analyzing bioreactor model. Bifurcation analysis is found to be a powerful tool for obtaining a more efficient and complete characterization of the model …
"The Neumeister Collection Of Chorale Preludes Of The Bach Circle": An Examination Of The Chorale Preludes Of J. S. Bach And Their Usage As Service Music And Pedagogical Works, Sara Ann Jones
LSU Doctoral Dissertations
One of the most significant discoveries of the twentieth century was the finding of an unpublished compendium of German Baroque keyboard music in 1982 in the archives of the John Herrick Music Library, Yale University, by musicologists Christoph Wolff and Hans-Joachim Schultz and Yale University librarian Harold E. Samuel. The collection, which was entitled LM 4708: THE NEUMEISTER COLLECTION OF CHORALE PRELUDES OF THE BACH CIRCLE, contains eighty-two previously unknown chorale preludes by several prominent German Baroque organists including Johann Pachelbel (1653-1706), Johann Michael Bach (1648-1694), Johann Christoph Bach (1642-1703), and Johann Sebastian Bach (1658-1750). Historically, it is an important …
Nursing As Social Responsibility: Implications For Democracy From The Life Perspective Of Lavinia Lloyd Dock (1858-1956), Soledad Mujica Smith
Nursing As Social Responsibility: Implications For Democracy From The Life Perspective Of Lavinia Lloyd Dock (1858-1956), Soledad Mujica Smith
LSU Doctoral Dissertations
This dissertation focuses on Lavinia Lloyd Dock's (1858-1956) re-envisioning of nursing and caring as social responsibility and the implications of this conceptualization for democracy. Dock was an American nurse, educator, settlement worker, suffragist, pacifist, social activist, writer, and historian. Her conception of holistic welfare embodied a 'new ideal' of society (Dock 1907, p. 899), a new understanding of democracy, and an expression of citizenship based on social responsibility for the welfare of others. Dock's idea of democracy embraced women's values and ways of being in the world; disputed universal, individual rights; and privileged communal values, collaboration, inclusion, and diversity. Moreover, …
The Culture Of Crime: Representations Of The Criminal In Eighteen-Century England, Daniel Gonzalez
The Culture Of Crime: Representations Of The Criminal In Eighteen-Century England, Daniel Gonzalez
LSU Doctoral Dissertations
This dissertation explores how literary criminal narratives reflected public anxieties over the increasing commercialization of England during the early eighteenth century. It accounts for the popularity of the criminal in literature as well as public concerns about commercialization and the individuality it encouraged, revealing how these concerns were expressed in the most popular form of criminal narrative in this era, the criminal biography. Chapters on the criminal narratives of John Bunyan, Daniel Defoe and John Gay reveal how the criminal narrative functioned as a means of critiquing a developing commercial society in England. Bunyan first employs the formula of the …
La Poetique Du Paysage Dans L'Oeuvre D'Edouard Glissant, De Kateb Yacine Et De William Faulkner, Nabil Boudraa
La Poetique Du Paysage Dans L'Oeuvre D'Edouard Glissant, De Kateb Yacine Et De William Faulkner, Nabil Boudraa
LSU Doctoral Dissertations
This dissertation examines the different ways in which Edouard Glissant, Kateb Yacine and William Faulkner combine landscape, history and identity in their work. The depiction of landscape in literature is not new, but the French Romantics in the 19th century, for instance, tended to describe the beauty of landscape without conceiving any rapport between landscape and humankind, and thus created a gap between the two. For Kateb and Glissant, landscape is also a witness of History. The (hi)story of their respective communities has been confiscated and shattered by the respective colonizers, hence the necessity to recreate it through the poetics …
The Impact Of Gruesome Evidence On Mock Juror Decision Making : The Role Of Evidence Characteristics And Emotional Response, Robert J. Nemeth
The Impact Of Gruesome Evidence On Mock Juror Decision Making : The Role Of Evidence Characteristics And Emotional Response, Robert J. Nemeth
LSU Doctoral Dissertations
Two experiments were conducted to investigate the effects of gruesome evidence on mock jurors? decisions in a simulated capital trial. The first experiment was designed as a replication and extension of Douglas, Lyon, and Ogloff (1997), who found that mock jurors who were presented with gruesome photographic evidence were nearly twice as likely to convict the defendant than participants who did not see the gruesome evidence. In Experiment 1, gruesome evidence was manipulated in two ways: photographic evidence (low gruesome, highly gruesome, or control photographs) and verbal testimony (low gruesome vs. highly gruesome). Neither photographic evidence nor testimony had an …

Prophet Singer: The Voice And Vision Of Woody Guthrie, Mark Allan Jackson
LSU Doctoral Dissertations
This project discusses the cultural and political significance of a number of lyrics by songwriter and political activist Woodrow Wilson "Woody" Guthrie. By drawing on both the singer's personal experiences and relevant American history, I lay out how larger political and cultural forces in society impacted Guthrie's songs. Although this work focuses primarily on his lyrics, my dissertation also draws on his interviews, commercial recordings, drawings, and other writing. Since much of the writing discussed in this work comes from archival collections at the Smithsonian Institution, the Library of Congress, and the Woody Guthrie Archives, I have covered a wider …
Essays On The Bayesian Inequality Restricted Estimation, Asli K. Ogunc
Essays On The Bayesian Inequality Restricted Estimation, Asli K. Ogunc
LSU Doctoral Dissertations
Bayesian estimation has gained ground after Markov Chain Monte Carlo process made it possible to sample from exact posterior distributions. This research aims at contributing to the ongoing debate about the relative virtues of the Frequentist and Bayesian theories by concentrating on the qualitative dependent variable models. Two Markov Chain Monte Carlo (MCMC) methods have been used throughout this dissertation to facilitate Bayesian estimation, namely Gibbs (1984) sampling and the Metropolis (1953, 1970) Algorithm. In this research, several Monte Carlo experiments have been carried out to better understand the finite sample properties of Bayesian estimator and its relative performance to …
Essays On International Trade And Bayesian Forecasting, Dennis S. Edwards
Essays On International Trade And Bayesian Forecasting, Dennis S. Edwards
LSU Doctoral Dissertations
Economic theory is subject to continual analysis. While theories themselves are sometimes widely accepted, nuances of theory are persistently scrutinized. Researchers have not isolated this debate from a simply theoretic standpoint. Empirical methods in microeconomics also provide a forum for disagreement. This dissertation studies two topics of microeconomic theory that are constantly in debate: integration and cost function estimation. From the standpoint of theoretical integration models in international trade theory, the concept of foreign direct investment is studied in both a horizontal and vertical setting. With respect to horizontal integration, this dissertation modifies the Brander-Krugman reciprocal dumping model to evaluate …
Spirit Matter(S): Post-Dualistic Representations Of Spirituality In Fiction By Walker Percy, Toni Morrison And Gloria Naylor, Likourgos James Vassiliou
Spirit Matter(S): Post-Dualistic Representations Of Spirituality In Fiction By Walker Percy, Toni Morrison And Gloria Naylor, Likourgos James Vassiliou
LSU Doctoral Dissertations
Spirit Matter(s): Post-Dualism Representations of Spirituality in Fiction by Walker Percy, Toni Morrison and Gloria Naylor, examines the ways in which these authors have presented spirituality in The Moviegoer, Song of Solomon, and Mama Day respectively. In these works, spirituality is a need for connection among humans in this world, rather than a notion that points to dualistic views of the spiritual and the material as two different realms. Through this perspective on spirituality as a reality of the physical world, the political and socio-economic problems of the world are not—nor can they be—set aside in favor of the spiritual …

Wetland groundwater hydrology was investigated at different spatial scales to assess the usefulness of the information to coastal managers. Specific objectives were to: (1) review studies related to coastal groundwater discharge, evaluating techniques and identifying controls; (2) understand regional trends in groundwater flow along the U.S. East and Gulf coasts; (3) evaluate the applicability of naturally occurring radioisotopes as indicators of groundwater in a shallow deltaic system; and (4) evaluate groundwater-surface water exchange within Barataria Basin, Louisiana. Results of the review confirmed discharge estimates vary over several orders of magnitude, due to differences in precipitation and tidal prisms. In addition, …
High Resolution Modeling Of Transport In Porous Media, Guangli Liu
High Resolution Modeling Of Transport In Porous Media, Guangli Liu
LSU Doctoral Dissertations
This dissertation presents research on the pore-level modeling of transport in porous media. The focus of this work is on high-resolution modeling, a rigorous approach that represents detailed geometry and first-principle physics at the streamline scale. Three major topics are presented in this dissertation: an efficient approach for solving Stokes flow in essentially arbitrary disordered porous media, high-resolution versus network simulations of dispersion phenomena, and a stochastic model for solving interfacial mass transfer from source spheres in porous media. First an approach was developed for solving the Stokes flow problem in a comparatively large, very heterogeneous two-dimensional porous media with …
A Game Theoretic Analysis Of U.S. Rice Exports Under Alternative Japanese And South Korean Policy Scenarios, Dae-Seob Lee
A Game Theoretic Analysis Of U.S. Rice Exports Under Alternative Japanese And South Korean Policy Scenarios, Dae-Seob Lee
LSU Doctoral Dissertations
As a result of the Uruguay Round (UR), the impact on the international rice market is profound. In addition, another round of the WTO trade negotiations has started and the impacts of potential policy changes on rice trade are unknown. The major U.S. benefit of the UR has been the access to the Japanese market. However, the U.S. share of this import market has been unstable and the share of Korean rice market is zero percent. Therefore, this study attempts to analyze the potential implication of U.S. rice exports to Japan and Korea. The Japanese and Korean rice economies as …

Role Of Chondrocyte Apoptosis In The Pathogenesis Of Equine Osteoarthritis, Dae Young Kim
Role Of Chondrocyte Apoptosis In The Pathogenesis Of Equine Osteoarthritis, Dae Young Kim
LSU Doctoral Dissertations
Osteoarthritis (OA), a non-inflammatory, degenerative disease of articular cartilages, is a common cause of poor performance and early retirement in equine athletes. Pathologically, OA is characterized by matrix degradation and decreased chondrocyte numbers. A mechanical stress is believed to be the major etiologic factor of OA development. Recent studies have indicated that apoptosis is responsible for hypocellularity in OA cartilage and that chondrocyte death by apoptosis could directly contribute to matrix degradation. Increased nitric oxide (NO), a free radical, has been implicated as a cause of chondrocyte apoptosis. No studies, however, have been performed on chondrocyte apoptosis in equine OA. …
An Empirical Analysis Of The Macroeconomic Effects Of Government Purchases, Eric Horent
An Empirical Analysis Of The Macroeconomic Effects Of Government Purchases, Eric Horent
LSU Doctoral Dissertations
This dissertation investigates the implications of different methods of identifying exogenous shocks to defense purchases for estimating the macroeconomic effects of shocks to government purchases. Four identification schemes are examined: the narrative approach of Ramey and Shapiro (1997), a more comprehensive narrative approach that tries to isolate exogenous reductions in defense purchases as well as exogenous increases in defense purchases, the Choleski decomposition, and long-run restrictions. The effects of alternative methods of identifying policy shocks are examined within two common VAR systems estimated over specific sample periods. The benchmark model includes four lagged values of defense purchases, real GDP, the …
Molecular Systematics, Phylogeography, And Population Genetics Of Xiphorhynchus (Aves: Dendrocolaptidae) In The Amazon Basin, Alexandre Aleixo
Molecular Systematics, Phylogeography, And Population Genetics Of Xiphorhynchus (Aves: Dendrocolaptidae) In The Amazon Basin, Alexandre Aleixo
LSU Doctoral Dissertations
Among those few hypotheses amenable to falsification by phylogenetic methods concerning the diversification of the Amazonian biota, three can be singled out because of their verifiable predictions: the riverine barrier, the gradient, and the basal trichotomy hypotheses. I used phylogenetic and population genetics methods to reconstruct the diversification history of the genus Xiphorhynchus (aves: Dendrocolaptidae) in Amazonia. First, I estimated the phylogeny of the entire genus Xiphorhynchus to test a key prediction of the gradient hypothesis; secondly, I documented phylogeographies of a superspecies associated with upland forest (X. spixii / elegans) and two species linked to floodplain forest (X. kienerii …
Aspects Of The Behavioral Ecology, Life History, Genetics, And Morophology Of The Hawaiian Kuhliid Fishes, Lori Keene Benson
Aspects Of The Behavioral Ecology, Life History, Genetics, And Morophology Of The Hawaiian Kuhliid Fishes, Lori Keene Benson
LSU Doctoral Dissertations
Flagtails, members of the Genus Kuhlia, are Indo-Pacific fishes found in marine and freshwater habitats. Known locally as Äholehole, they are important food fishes in the Hawaiian Islands and were often used by Hawaiians in traditional ceremonies. Local fishermen have noted the presence of two morphotypes in Hawai'i, although at the beginning of this study only one species, Kuhlia sandvicensis, was identified in the scientific literature. For this dissertation research, morphological and DNA studies of the two morphotypes determined that two species of the genus Kuhlia do exist in Hawai'i. Subsequently, Randall and Randall (2001) published a revision of this …

Effects Of Fire Frequency And The Red Imported Fire Ant On Native Insects In A Louisiana Longleaf Pine Savanna, Deanna M. Colby
LSU Doctoral Dissertations
Ants and ground beetles were collected in pitfall traps from a longleaf pine savanna in the early stages of restoration. Insect abundance and species richness were compared among four treatment combinations of two fire frequencies and presence and absence of an exotic ant, Solenopsis invicta, the red imported fire ant. Amdro® was used to suppress S. invicta. Fire treatments consisted of a single fire in a two year period or two fires in a two year period, one applied each year. Fires were applied late in the growing season both years. Ten of the 28 ground beetle species …
Prevention Of Eating Disorders In Athletes: An Intervention For Coaches, Brooke L. Whisenhunt
Prevention Of Eating Disorders In Athletes: An Intervention For Coaches, Brooke L. Whisenhunt
LSU Doctoral Dissertations
Research has found that athletes, particularly those involved in "aesthetically-oriented" sports, are at increased risk for engaging in unhealthy weight reduction practices and developing clinical eating disorders. Prevention studies of eating disorders have had some success, but there are very few published studies that address prevention in athletes. This study was designed as an eating disorders prevention program that targeted coaches as change agents. Cheerleading coaches at national or regional conferences attended an intervention workshop or a control workshop. Coaches who attended the intervention workshop received information regarding nutrition, eating disorders, and ways to manage athletes with eating disorders. They …
