Differences Across Racial Groups In Caregiver Ratings Of Symptoms In Children Diagnosed With Autism Spectrum Disorders, Cindy Terlonge Graham

LSU Doctoral Dissertations

A great deal of attention from local, federal, and international communities has been focused on autism spectrum disorders (ASDs). As the prevalence of these disorders rise, researchers continue to investigate various unanswered questions. The goal of this study was to examine the differences across racial/ethnic groups in caregiver ratings of symptoms of children diagnosed with ASDs. Results from such research will help determine whether cultural background can influence the recognition of behaviors indicative of an ASD. Culturally-sensitive clinical practice stemming from the significant findings of this research project can help to reduce the age at which minority children are diagnosed. …

The Long Road Home: Alfred Andersch, Hans Werner Richter, And The German Search For Meaning In Catastrophe, Aaron Dennis Horton

LSU Doctoral Dissertations

The primary subjects of this dissertation are the post-World War II German authors Alfred Andersch and Hans Werner Richter. Drawing from a mixture of the authors’ writings and previously-researched as well as new archival sources, this study will examine their roles as editors of the U.S. Army-sponsored POW newspaper Der Ruf, as founders of the postwar West German journal, also titled Der Ruf, and, most famously, as founding members of the influential postwar West German literary circle Group 47. Each of these developments led directly to the next, and this study will explore the various processes that linked them together. …

"Baby, Dream Your Dream": Pearl Bailey, Hello, Dolly!, And The Negotiation Of Race In Commerical American Musical Theatre, Charles Eliot Mehler

LSU Doctoral Dissertations

In October of 1967, producer David Merrick closed his successful production of Hello, Dolly! Merrick reopened the show one month later with an all-black cast that featured the talents of performers Pearl Bailey and Cab Calloway. While this Bailey Dolly! was a mammoth commercial success, this production brought attention to various problems concerning the interaction of black and white creative and performing talent in the venue of commercial American musical theatre. One such problem involved the risk of possible loss of genuine black culture and ignorance of recalcitrant intra-black-community difficulties and the extent to which African Americans should have desired …

Ethnic Online Newspapers Vs. Mainstream Online Newspapers: A Comparison Of The News Coverage Of The 2010 Health Care Reform Debate, Masudul Biswas

LSU Doctoral Dissertations

This study examined the news coverage of the 2010 health care reform in a comparative context of mainstream and ethnic online newspapers. Since health care reform had consequences among all ethnic groups in the U.S., the news coverage of this policy issue warranted an analysis in a diverse media context. The importance of this study lies in the fact that diverse news media provide a wide range of perspectives to the public and policymakers for a better understanding of an issue at stake. In past studies, mainstream media coverage was criticized for emphasizing political conflict and gains and losses over …

Historical Études For Oboe: 17th-20th Centuries, Linwood William Zoller Iv

LSU Doctoral Dissertations

The most popular étude books for oboe in use today are Ferling’s 48 Studies (1840) and Barret’s Complete Method for Oboe (1850). Many earlier and later collections exist, but most oboists only study from these two. This monograph uses four main criteria to choose sample études from various other collections and compile them into a single étude book. These criteria include: representation of major style periods; quotations from famous excerpts for oboe or difficult passages therefrom; illustration of mechanical improvements of the time and location; and alternatives to the standard canon in established pedagogy. Thirteen études, arranged chronologically, were selected …

Numerical Methods For The Study Of Super-Eddington Mass Transfer In Double White Dwarf Binaries, Dominic Carlo Marcello

LSU Doctoral Dissertations

We present a numerical method for the study of double white dwarf (DWD) binary systems at the onset of super-Eddington mass transfer. We incorporate the physics of ideal inviscid hydrodynamical flow, Newtonian self-gravity, and radiation transport on a three-dimensional uniformly rotating cylindrical Eulerian grid. Our new method conserves total energy to a higher degree of accuracy than recent smoothed particle hydrodynamics methods and our previous Eulerian grid based method. We present the results of verification tests and we simulate the first 20+ orbits of a binary system of mass ratio q=0.7 at the onset of dynamically unstable direct impact mass …

Population-Level Responses Of The Mummichog, Fundulus Heteroclitus, To Chronic Nutrient Enrichment In A New England Salt Marsh, Konner Chadwick Lockfield

LSU Master's Theses

Mummichog (Fundulus heteroclitus) responses to chronic whole-ecosystem nutrient enrichment were examined near Plum Island Sound, Massachusetts. Dissolved fertilizer was released into replicate salt marsh creeks over 6 growing seasons to simulate agricultural run-off (bottom-up effects). Density, biomass, secondary production, growth rate, and condition factor were estimated in fertilized and reference creeks. Mummichog densities were also used to determine if mummichog growth or health varied with density. Over 7,600 mummichogs were marked and released into the treatment and control areas to measure responses. Over 900 mummichogs were recovered. Mummichog abundance was higher (p = 0.055) in nutrient-enriched creeks than reference creeks …

Studies Of Inhomogeneous Superconducting States In Novel Materials, Robert Pearson Beaird

LSU Doctoral Dissertations

I provide detailed studies of two types of novel superconducting systems. In the first, I examine the effect of thermal (Gaussian) magnetic fluctuations on the superconducting transition of paramagnetically-limited superconductors under a Zeeman magnetic field. I consider transitions into both the uniform and the modulated (Fulde-Ferrell-Larkin-Ovchinnikov) superconducting states. I derive the Landau free energy expansion in powers of the superconducting order parameter, allowing for competition between the magnetic fluctuations and the superconducting order. I determine the order of the transition at the upper critical field and find that the fluctuations drive the transition, usually second-order, to first order at intermediate …

Electrochemical Etching Of Isolated Structures In P-Type Silicon, Joel Nino Bugayong

LSU Master's Theses

The role of the space charge region (SCR) was demonstrated in isolated structures for the first time. Electrochemical etching was conducted in differently pitched structures in p-type silicon. A design of experiment was also performed to evaluate the effect of electrolyte and applied potential. Finally chemical etching was demonstrated as a possible post-etch clean to porous structures. The results showed that the morphology of etched structures in pre-patterned silicon is strongly influenced by the SCR even in isolated structures. Using lightly-doped p-type Si (1,000-10,000 Ω-cm), deep macropores were obtained in wide-pitched patterns. However, the diameter of the pores grew larger …

Blind Yield Detection In Steel Structure For Automatic Nondestructive Testing Using Ultrasonic Sensors, Hongting Zhang

LSU Master's Theses

Detection of yield zones using nondestructive testing (NDT) technology for assessing the structural integrity of the existing steel buildings/bridges is extremely important. The average energy over the “effective echoes” (in “good” signal quality) is a robust feature for the yield detection in steel structures. Nevertheless, this average-energy feature extraction requires rigorous manual data-acquisition and human operation. Therefore, in this thesis, we make the first-ever attempt to design a totally-blind and automatic steel-structure yielddetection mechanism, which requires neither the a priori information about the signal nor the human effort in calibration, operation, or data analysis. This new scheme is built upon …

Three Essays On Tax Salience: Market Salience And Political Salience, David Gamage, Darien Shanske

Articles by Maurer Faculty

This Article analyzes the literatures on how individuals understand taxation (i.e., tax salience). We evaluate how taxpayers respond to different presentations of tax prices both in their roles as market participants and as voters. We aim to combat naïve notions about tax salience that currently exert a pernicious influence on tax lawmaking. In particular, we argue that it is normatively desirable for governments to reduce tax salience with respect to market decision making, and that there is nothing objectionable about governments reducing tax salience with respect to political decision making.

Thermodynamics Of Dna Binding And Break Repair By The Pol I Dna Polymerases From Escherichia Coli And Thermus Aquaticus, Yanling Yang

LSU Doctoral Dissertations

Klenow and Klentaq are the “large fragments” of the Pol I DNA polymerases from Escherichia coli and Thermus aquaticus. Examination of the DNA binding thermodynamics of both polymerases to replication versus repair substrates shows that Klenow binds primed-template DNA with up to 50X higher affinity than it binds to a nicked DNA, gapped DNAs, DNA with blunt-end or a 3’ overhang, while Klentaq binds all of these DNAs similarly. The presence of 5’ or 3’ phosphates has slightly different effects on DNA binding by both polymerases. In contrast, both polymerases bind mismatched DNA tighter than matched DNA, suggesting that they …

Temporal Changes In Quality Of Life And Environment In New Orleans After Hurricane Katrina, Danielle Johanna Larock

LSU Master's Theses

Understanding and assessing the spatial and temporal changes of quality of life and environment of a community is critical to its sustainable development, especially after a disaster strikes. This study explores an approach that integrates remote sensing with socioeconomic data to assess the temporal changes in quality of life and environment (QOL) using Orleans Parish as an example. Hurricane Katrina, which struck New Orleans in 2005, has had vast implications economically, socially, and environmentally for this city and the surrounding area. Empirically quantifying these concepts will help to rebuild the city more sustainably. This study investigated change in environmental quality …

Sacrifice And Sacred Honor: Why The Constitution Is A "Suicide Pact", Peter Brandon Bayer

Scholarly Works

Most legal scholars and elected officials embrace the popular clich6 that "the Constitution is not a suicide pact." Typically, those commentators extol the "Constitution of necessity," the supposition that Government, essentially the Executive, may take any action-may abridge or deny any fundamental right-to alleviate a sufficiently serious national security threat. The "Constitution of necessity" is wrong. This Article explains that strict devotion to the "fundamental fairness" principles of the Constitution's Due Process Clauses is America's utmost legal and moral duty, surpassing all other considerations, even safety, security and survival.

The analysis begins with the most basic premises: the definition of …

The Multi-Institutional Study Of Leadership At Lsu: How Participation In Specific Student Groups Affects One's Leadership, Courtney Elizabeth Lambert

LSU Master's Theses

Through statistical examination of the Multi-Institution Study of Leadership (MSL), conducted at Louisiana State University during the Spring of 2010, quantitative research sought to determine if different leadership outcomes are produced through membership in religious student organizations, multi-cultural fraternities and sororities, social fraternities and sororities, and intercollegiate or varsity athletic groups. The MSL is theoretically based on the Social Change Model of Leadership Development and the leadership outcomes it assesses are consciousness of self, congruence, commitment, collaboration, common purpose, controversy with civility, citizenship, and change. It was discovered that students in religious student organizations score better on many leadership outcomes, …

Testing And Improving The Luminosity Relations For Gamma-Ray Bursts, Andrew Collazzi

LSU Doctoral Dissertations

Gamma Ray Bursts (GRBs) have several luminosity relations where a measurable property of a burst light curve or spectrum is correlated with the burst luminosity. These luminosity relations are calibrated for the fraction of bursts with spectroscopic redshifts and hence the known luminosities. GRBs have thus become known as a type of "standard candle"; where standard candle is meant in the usual sense that their luminosities can be derived from measurable properties of the bursts. GRBs can therefore be used for the same cosmology applications as Type Ia supernovae, including the construction of the Hubble Diagram and measuring massive star …

Business Faculty Publications and Presentations

Tim O’Brien, founder of Tropical Salvage, was preparing for another warehouse clearance sale of his unique, handcrafted hardwood furniture. It had been an enormously challenging year and it was important to reduce inventory before the next container arrived from Indonesia. The market for fine furniture had begun to decline steadily in early 2008 following the stock market crash of the prior September. The company survived a difficult period, but not without suffering a decline in sales. O’Brien had spent ten years building a sustainable business model based on environmental stewardship, worker empowerment and unique, high quality product. As the economy …

Effect Of Piezoelectric Actuation On Curved Beams And Single Lap Joints, Calicia Johnson

LSU Master's Theses

Piezoelectric materials have seen a significant usage increase over the past decade. They have been found to be effective as either sensors or actuators in smart structure applications, which allows them to act more as an adaptive system rather than a passive system. Piezoelectric materials are very effective transducers which convert mechanical energy into electrical energy, known as the direct piezoelectric effect or they have the ability to convert electrical energy to mechanical energy, known as the converse piezoelectric effect. The absence of additional mechanical parts, its lightweight and high strength to weight ratio is what make piezoelectric materials so …

A Comprehensive Study Of Dust Formation And Evolution In Core Collape Supernovae, Jennifer Erin Andrews

LSU Doctoral Dissertations

Detection of large amounts of dust in high redshift galaxies suggests that core collapse supernovae (CCSNe) may play a critical role in the dust budget of galaxies in the early universe, when galaxies are only a few hundred million years old. At an age of only 1Gyr, asymptotic giant branch (AGB) stars may not have had the time to become significant dust contributors, leaving CCSNe as an alternative explanation since they quickly evolve and return their material to the surrounding interstellar medium. For the past three years, I have been observing the CCSNe 2007it and 2007od with Gemini, Hubble Space …

Utilizing Near-Infrared Spectroscopy To Detect Sodium Tripolyphosphate In Treated Penaeus Aztecus And Setiferus Shrimp, Alisa Marlene Todd

LSU Master's Theses

Applying sodium tripolyphosphate to shrimp may cause excess water absorption and has become a major concern to phosphate producers, the consumer and regulatory agencies, such as, the United States Food and Drug Administration. The objective of this study was to examine Near Infrared (NIR) spectroscopy as a nondestructive and rapid method of detecting shrimp treated with sodium tripolyphosphate solutions of varying concentrations and treatment times. Wild caught Penaeus setiferus and aztecus Louisiana gulf coast shrimp were submerged in distilled water, 2.5% sodium tripolyphosphate (STPP), and 5% sodium tripolyphosphate solutions for 30, 60, 120, 240, 480, 960, 1920 minute time intervals. …

Social Work Students' Attitudes Toward Teenage Pregnancy Prevention: The Importance Of Religiosity And Feminist Ideology, Pilar Thompson Borne

LSU Master's Theses

Effective teenage pregnancy prevention is a topic of debate in current literature. Religiosity is frequently examined in the research, and studies typically assess associations between behavior patterns and level of religiosity. Feminist ideology is another theme found in the teenage pregnancy prevention literature that mainly examines how feminist perspectives contribute to effective prevention approaches. The current study examined the interrelationships among religiosity, feminist ideology and attitudes toward teenage pregnancy prevention. A self-report survey instrument was used to collect data from 69 MSW students, a sample surveyed for the first with the current study. A significant positive correlation was found between …

Adams-Jefferson: An Inquiry Into Human, Nature, Politics, And The Implications For A Republic, Adetoyese Itunu Adedipe

LSU Master's Theses

If one were to inquire from Americans the names of five founding fathers, John Adams and Thomas Jefferson will more often than not be mentioned amongst them. Apart from being among the founders of the republic, these two men presided over the republic as well. It is accurate to say both founding fathers were prolific writers who left behind a wealth of literature their progeny could look to when it came to the intricacies of politics and the nature of man. The aim of this thesis is to unveil the metamorphosis of a political order via the views and opinions …

Cost And Performance Modeling Of The Mu-Decoder, Raghavendra Kongari

LSU Master's Theses

In this thesis we study the implementation details of the MU-Decoders, a recently proposed hardware module that has been theoretically shown to be superior to other methods for generating subsets of large sets. Our study confirms this advantage. Specifically, we compare the performance of implementations of the LUT-Decoder (the most common configurable decoder) to the MU-Decoder. We show that for while the LUT-Decoder is slightly better than the MU-Decoder for arbitrary (and artificial) inputs, for a large class of inputs called totally ordered subsets, that have practical significance, the MU-Decoder is vastly superior in area to the LUT-Decoder. In terms …

The Tick Response To Rickettsial Dissemination During Typical And Atypical Rickettsial Infection, Piyanate Sunyakumthorn

LSU Doctoral Dissertations

Ticks are the only disease vectors for spotted fever group (SFG) Rickettsia which are obligate intracellular bacteria belonging to the genus Rickettsia. In nature, ticks maintain the infection of SFG Rickettsia via vertical and horizontal transmission. However, the prevalence of rickettsial transmission is limited to certain species of ticks, and this limitation is known as a specific tick/Rickettsia relationship. Due to the continuous increase of tick-borne rickettsial disease cases in the United States, which contrasts with very low prevalence of Rickettsia in tick vectors, the study of vector competence of tick to Rickettsia is needed in order to understand the …

Difficulty Disengaging Attention From Appearance Words Among Women With High Social Anxiety, Jose Silgado

LSU Master's Theses

Pathological eating behaviors (PEB) and body dissatisfaction are more prevalent among women with higher social anxiety (HSA) than women with lower social anxiety (LSA). Attentional bias may play a role in these relationships. Attentional bias toward appearance is related to PEB and body dissatisfaction. Further, difficulty disengaging attention from threat is thought to maintain anxiety among HSA individuals. It follows that some HSA women may find scrutiny regarding their appearance threatening and difficulty disengaging attention from appearance cues may play an especially important role in PEB and/or body dissatisfaction among HSA women. The present study tested this theory, hypothesizing that: …

Feedback Control For Exergames, Jeff Sinclair

Theses: Doctorates and Masters

The concept of merging exercise equipment with video games, known as exergaming, has the potential to be one of the main tools used in addressing the current rising obesity epidemic. Existing research shows that exergaming can help improve fitness and additionally motivate people to become more active. The two key elements of attractiveness - how much people want to play or use the exergaming system; and effectiveness – how effective the exergaming system is in actually increasing or maintaining physical fitness, need to be maximised to obtain the best outcomes from an exergaming system; we put this forward as the …
