Methylation Patterns And Phenotypes Of The R-Stippled Derivatives Lines, Kara D. Dragone

Electronic Theses and Dissertations

Paramutation occurs between trans-alleles with homologous sequences resulting in a heritable change in gene expression, where epigenetic information from one allele is passed to the other. In maize, the paramutagenic r1 allele, R-stippled, silences the paramutable allele, R-r:standard, following paramutation. The R-r:standard allele is known to show increased methylation following paramutation. The R-stippled allele, which is composed of the four genes, Sc, Nc1, Nc2 and Nc3, becomes less paramutagenic as genes are lost. Sc alone is not paramutagenic. I hypothesized that the R-stippled derivative containing two genes would be less methylated at cytosine residues than the four-copy allele, particularly in …

LSU Doctoral Dissertations

Psychological analysis related to voluntary reciprocal trust games were obtained using functional magnetic resonance imaging (fMRI) hyperscanning for 44 pairs of strangers throughout 36 trust games (TG) and 16 control games (CG). Hidden Markov models (HMMs) are proposed to train and classify the fMRI data acquired from these brain regions and extract the essential features of the initial decision of the first player to trust or not trust the second player. These results are evaluated using the different versions of the multifold cross-validation technique and compared to other speech data and other advanced signal processing techniques including linear classification, support …

Mathematical And Computer-Based Models For Optimizing Microwave Heating Processes Of Frozen Oysters, Jie Zhang

LSU Doctoral Dissertations

Consumers with full-time jobs prefer microwavable-frozen-meals for convenience when lack time to cook. Microwaves do not require a medium for heat transfer and provide quick heating even in low thermal conductivity foods, which does not occur in conventional heating. The main problem in utilizing microwave-heating for cooking is the non-uniform temperature distribution in foods which may result in insufficient lethality of microorganisms in some part. This non-uniformity can be due to a number of factors including composition and geometry of food. The objectives of this study were to develop a mathematical-model based on Maxwell¡¯s equations for predicting the temperature distribution …

Luminescence Studies : Part I. Lanthanide Nanogumbos Part Ii. Near Infrared Photothermal Nanogumbos, Jonathan Carver Dumke

LSU Doctoral Dissertations

Group of Uniform Materials Based on Organic Salts (GUMBOS) are a class of molten salts that have been focused to be specifically tailored towards applications. Primitively, from Davy to Walden molten salts were desirable for organic synthesis due to the properties. GUMBOS have been synthesized into nanoparticles (nanoGUMBOS) by various methods to be used for lanthanide luminescence and hyperthermal cancer therapeutics. Lanthanide photochemistry has been frequently studied for its high luminescence intensity, narrow emission band, and stable luminescent lifetime decay. Aerosol-derived europium nanoGUMBOS were characterized using electron microscopy (39.5 ± 8.4 nm), XPS, and spectroscopic techniques. Spectroscopic measurements indicated intense …

Aesthetics In The Classroom For Social Justice : How Do The Theories Of John Dewey, Maxine Greene, And Jane Piirto Inform Us?, Valerie Meiners Comeaux

LSU Doctoral Dissertations

This study asks 1) What is the relationship between art, creativity, and social justice? 2) How do the theories of John Dewey, Maxine Greene, and Jane Piirto inform our understanding of this relationship? 3) What is the role of the arts in contemporary curriculum? To answer these questions, the study chronicled the various roles of art in Western society, from Classical Greece through the present day, before exploring the aesthetic theories of Dewey, Greene, and Piirto. The findings suggest that the absence of an arts-integrated curriculum in most American public schools does not imply the absence of art programs in …

The themes that emerged as a result of the analysis are as follows: (a) Afterschool …

Analyzing The Effects Of Context-Aware Mobile Design Principles On Student Performance In Undergraduate Kinesiology Courses, Eric John Seneca

LSU Doctoral Dissertations

Learning occurs when content is accessed in a recursive process of awareness, exploration, reflection and resolution within one’s social context. With the rapid adoption of mobile technologies, mobile learning (m-Learning) researchers should incorporate aspects of mobile human-computer interaction research into the instructional design process. Specifically, the most visible, current definitions of and current research in m-Learning provide overviews of the learning theory informing mobility and focus on device characteristics, but do not focus on how people interact with mobile devices in their every day lives. The purpose of this convergent study was to determine what effect does the incorporation of …

Geodatabase-Assisted Storm Surge Modeling, Sait Ahmet Binselam

LSU Doctoral Dissertations

Tropical cyclone-generated storm surge frequently causes catastrophic damage in communities along the Gulf of Mexico. The prediction of landfalling or hypothetical storm surge magnitudes in U.S. Gulf Coast regions remains problematic, in part, because of the dearth of historic event parameter data, including accurate records of storm surge magnitude (elevation) at locations along the coast from hurricanes. While detailed historical records exist that describe hurricane tracks, these data have rarely been correlated with the resulting storm surge, limiting our ability to make statistical inferences, which are needed to fully understand the vulnerability of the U.S. Gulf Coast to hurricane-induced storm …

Optimization Of Feline Adipose-Derived Multipotent Stromal Cell Isolation And Canine Cranial Cruciate Ligament Regeneration With Intra-Articular Adipose-Derived Multipotent Stromal Cells, Nan Zhang

LSU Doctoral Dissertations

Adult multipotent stromal cells (MSCs) have become popular within veterinary sciences for direct administration and tissue regeneration due to their differentiation, trophic and immunosuppressive properties. However, current isolation and expansion techniques provide a heterogeneous population with other types of cells, which may affect the efficiency and efficacy of treatments. The progenitor properties and function need to be further evaluated in vitro prior to in vivo application. The first part of this dissertation was to identify the optimal MSC source for general canine orthopedic applications such as intra-articular injection and joint tissue regeneration. Based on side-by-side comparisons of cell doublings, colony …

Essays On Credit Default Swaps And Debtor-Creditor Relationships, Cihan Uzmanoglu

LSU Doctoral Dissertations

Over the last decade, markets for credit insurance have developed dramatically and credit default swaps (CDS) have become the instrument of choice when it comes to hedging credit risks. The expanded hedging opportunities CDS provide and the allied benefits of better risk-sharing notwithstanding, concerns over the economic role of CDS arise from their ability to engender “empty” creditors – joint holders of the bond and CDS, and the role such creditors play in distress situations. Financially distressed firms often restructure their debt through out-of-court renegotiations with creditors to avoid formal default. In addition to the going concern value of the …

Relational Aggression, Social Aggression, And Antisocial Personality Features: An Investigation Of Bullying Behavior In A Sample Of Juvenile Offenders, George Ronald Bell

Electronic Theses and Dissertations

Bullying is a destructive subtype of aggression that can take direct and indirect forms. This study investigated relationships between two indirect forms of bullying (relational aggression and social aggression), the aggressor's level of interpersonal maturity, and antisocial personality features (narcissism and callous-unemotional traits). Participants included 58 male and 21 female offenders between the ages of 13 and 18 from an urban school serving youth who were adjudicated through the juvenile justice system.

Molecular Dynamics Simulation Studies Of Interaction Of Amphiphilic Molecules With Lipid Bilayers, Jieqiong Lin

LSU Doctoral Dissertations

We use molecular dynamics simulations to investigate the behavior of various amphiphilic molecules in aqueous solutions in the presence of vitamin E or lipid bilayers. Our research studies focus on two molecular systems. First, we investigate the effect of DMSO on structural properties of DMPC bilayers and calculate bilayers permeability coefficients for both water and DMSO molecules at low DMSO concentration. The simulations show that the increase of DMSO concentration in solution leads to an increase of the permeability of water through the bilayers. The permeability increase might explain the unusual ability of DMSO, even at relatively low concentrations, to …

High Capacity Digital Beam Steering Technology, Daniel James Hebert

LSU Doctoral Dissertations

A novel method is described in detail for steering light in many directions without moving mechanical parts. The method involves a combination of liquid crystal cells and polarizing beam splitters. The polarization at each beam splitter is controlled by applying a signal to its corresponding liquid crystal cell. A study of light steering techniques is described for efficient beam placement, in a line and plane. These techniques permit accurate, non-mechanical, beam steering limited by the response time of the liquid crystal cells. A theoretical limit to the number of discrete directions is described and closely approached for a one dimensional …

Effects Of Semantic + Multimodal Communication Program For Switching Behavior In Severe Aphasia, Shannon A. Carr

Electronic Theses and Dissertations

Treatment for severe aphasia includes teaching alternative modalities to improve communicative effectiveness by circumventing deficits in verbal expression. Traditionally, alternative communication modalities are trained separately to augment or replace verbal output. However, adults with aphasia often have executive function deficits, specifically deficits in cognitive flexibility, which affect the communicative flexibility of the individual. The result is an inability to switch to a previously learned alternative modality when a communication breakdown occurs. This study explored a combined semantic + multimodal communication program (S+MCP) for an individual with severe aphasia and coexisting semantic deficits. The effect of S+MCP on his ability to …

Poultry Litter Ash As A Phosphorus Source For Greenhouse Crop Production, Daniel Evan Wells

LSU Doctoral Dissertations

Phosphorus (P) is an essential nutrient for all life forms, including plants, but is a limited agricultural resource whose future availability is in question. Therefore, identification of alternative forms of P fertilizers is important. Poultry litter ash (PLA), a byproduct of bioenergy production, contains high concentrations of P comparable to conventional fertilizers. Forms of P contained in PLA have been characterized as having low water solubility. Nutrient losses during containerized plant production are high due to excessive inputs of water and nutrients and low nutrient sorption capacities of common horticultural substrate components. Environmental concerns over reduced water quality intensify this …

"Individual Yet As One": Performing Deafness And Performing Community In Mark Medoff's Children Of A Lesser God, Mariah Crilley

Electronic Theses and Dissertations

In this thesis, I examine the relationship between deafness, women, and performance in Mark Medoff's Children of a Lesser God. The play was a massive popular success, both in its run on Broadway and its movie adaptation. Deafness and deaf people had never been so visible in American hearing culture. More importantly, the play coincided with civil rights movements by people with disabilities, which culminated in the passage of the Americans with Disabilities Act. Disabilities, including deafness, were called into being as part of a national identity. These movements posited self-determination but ultimately relied and thrived on a communal and …

Molecular Evolution Of Hominoid Seminal Plasma Genes, Sarah Jean Carnahan Craig

Electronic Theses and Dissertations

When asking the question of what underlying genetic changes drive species to be different, it is debated whether protein coding or non-coding mutations are more important. The hominoids (humans, great apes, and gibbons) are a group of closely related species, yet vary widely in their mating system behaviors and predicted levels of sperm competition. In species where females mate with multiple males, sperm competition is hypothesized to increase the rate of adaptive evolution of proteins expressed in male reproductive tissues through recurrent selective sweeps (positive selection). Previous studies have shown this to be true for individual male reproductive genes. In …

Fast And Reliable Detection Of Incumbent Users In Cognitive Radios, Mahdi Orooji

LSU Doctoral Dissertations

Fast and reliable Spectrum Sensing (SS) plays a crucial role in the cognitive radio (CR) technology in order to prevent unwanted interference to the primary users (PU) and to reliably and quickly detect the white spaces in the spectrum for opportunistic access by the secondary users (SU). Spectrum Sensing must often be performed in the absence of information such as PU signaling scheme, noise level and channel fading coefficients. While these parameters can be estimated in the SU, estimation errors significantly deteriorates the performance of SS techniques. In this thesis, we introduce and evaluate the performance of two novel blind …

LSU Doctoral Dissertations

Ecological literacy in students has become an increasing concern for educators. Mounting environmental problems along with a growing amount of nature deficit disorder seen in children and adults alike provides the impetus for research in this area. Since many college biology classes are modeled around the same style and emphasis found in the textbooks used for those courses, this provided an avenue for an examination of these materials. This research involved the selection of five popular introductory, college-level biology textbooks for analysis. Three rubrics were created to assess the graphical components of the introductory and ecology chapters in each textbook. …

Starting Scholarly Conversations: A Scholarly Communication Outreach Program, Andrea M. Wright

Libraries Publications

As the scholarly communication system continues to evolve, academic librarians should take an active role in both developing their own knowledge and educating their campus communities about emergent topics. At Furman University, librarians developed an outreach program, aimed primarily at faculty, to increase awareness of current scholarly communication issues. Expert speakers were recruited to present throughout the year on open access, altmetrics, author’s rights, and other relevant topics. This program addressed a number of needs simultaneously— outreach to faculty; education for Furman librarians; and education for the greater library community—and affirmed the importance of providing opportunities to discuss these issues …

Disaggregating Disasters, Lisa Grow Sun, Ronnell Andersen Jones

Faculty Scholarship

In the years since the September 11 attacks, scholars and commentators have criticized the emergence of both legal developments and policy rhetoric that blur the lines between war and terrorism. Unrecognized, but equally as damaging to democratic ideals—and potentially more devastating in practical effect—is the expansion of this trend beyond the context of terrorism to a much wider field of nonwar emergencies. Indeed, in recent years, war and national security rhetoric has come to permeate the legal and policy conversations on a wide variety of natural and technological disasters. This melding of disaster and war for purposes of justifying exceptions …

The Rhetorical Strategies Of Don Quixote And Sancho Panza, David T. Tarvin

LSU Doctoral Dissertations

This dissertation explores the rhetorical components of the famous novel Don Quixote by Miguel de Cervantes. Cervantes’ novel continues to be celebrated around the world four hundred years later. His two main protagonists epitomize opposite virtues, but their love for one another, and the promise of an ínsula, creates a bond that overcomes their differences. Don Quixote, the mad knight, values lofty ideas idealized in chivalric romance. Conversely, Sancho, the simple squire, values tangible materials he can see and touch in his own life. While the two characters first appear to be contrary in nature, by the journey’s end, as …
