Holy Or Unholy Matrimony: Does Participation In A Pre-College Program Influence The Retention Rate Of African American Males In College, James Dj Baker Iii
Holy Or Unholy Matrimony: Does Participation In A Pre-College Program Influence The Retention Rate Of African American Males In College, James Dj Baker Iii
LSU Doctoral Dissertations
Fifty percent of all students who enroll in college depart before earning their degree; this proportion is even higher among minorities during the first year of college (Tinto, 2006). Minorities have typically had fewer opportunities to gain a college education. Once enrolled in college, minorities have generally found it more difficult to succeed academically and graduate (Strayhorn, 2011). There is one group among the collective of minorities that are even further behind the rest, African American males. African American males are one of the most underrepresented populations of students on college campuses around the nation (Feagin, Vera, & Imani, 1996). …
The Lost City: Examining The Relationship Between Science, Philosophy And The Atlantis Myth, Kimberly Hurd
The Lost City: Examining The Relationship Between Science, Philosophy And The Atlantis Myth, Kimberly Hurd
LSU Doctoral Dissertations
Francis Bacon, long considered a minor figure in the founding of modern political thought, is now recognized as one of its foremost thinkers. Bacon not only championed a new type and method of scientific inquiry, he also developed a plan for how modern society could be re-ordered to accommodate and promote scientific progress. Bacon’s scientific writings cannot be wholly understood apart from his political writings, and many of his works combine the two topics so subtly that it is difficult to even place them in a definitive category. My project expands on the previous literature with a detailed analysis of …
Field Investigation Of Wave And Surge Attenuation In Salt Marsh Vegetation And Wave Climate In A Shallow Estuary, Ranjit S. Jadhav
Field Investigation Of Wave And Surge Attenuation In Salt Marsh Vegetation And Wave Climate In A Shallow Estuary, Ranjit S. Jadhav
LSU Doctoral Dissertations
This research investigates and quantifies the effectiveness of salt marsh vegetation in reducing storm-induced waves and surge, and the potential for wetland erosion due to wave action, using field measurements on the Louisiana coast. To quantify wave attenuation and wave energy dissipation by vegetation (Spartina alterniflora), wave data were measured along a transect using pressure transducers during two tropical storms. Measurements showed that incident waves attenuated exponentially over the vegetation. The linear spatial wave height reduction rate increased from 1.5% to 4% /m as incident wave height decreased. The bulk drag coefficient estimated from the field measurements decreased with increasing …
What Does The ¹⁴C Method For Estimating Photosynthetic Rates In The Ocean Really Measure?, Shaofeng Pei
What Does The ¹⁴C Method For Estimating Photosynthetic Rates In The Ocean Really Measure?, Shaofeng Pei
LSU Doctoral Dissertations
The 14C method has been used extensively by both limnologists and oceanographers to measure photosynthetic rates in aquatic systems, and the large database of 14C measurements that now exists is the ground truth with which satellite algorithms for estimating marine photosynthetic rates on a basin and global scale have been calibrated. However, disconcerting uncertainties still remain with respect to whether and under what circumstances the 14C method provides an estimate of net or gross photosynthesis, or something in between. My study combined batch and continuous culture studies to clarify this ambiguous issue. The batch culture work with …
Communicating While Stimulated: The Effects Of Sensory-Processing Sensitivity On Behavior And Relationships, Christopher Charles Gearhart
Communicating While Stimulated: The Effects Of Sensory-Processing Sensitivity On Behavior And Relationships, Christopher Charles Gearhart
LSU Doctoral Dissertations
In light of claims made by Aron (1996, 2000; Aron & Aron, 1997), this dissertation tested the influence of sensory-processing sensitivity on communication via two sets of research questions. First, are highly sensitive persons more easily aroused by stimulation, and if so does this necessarily cause a decrease in affect recognition? Results of an experimental study (N = 342) indicate that highly sensitive persons (HSPs) were more distracted by audio stimulation, causing more errors in accuracy judgments on non-verbal decoding tests, most noticeably for facial expression detection. The implication is that, when aroused by stimulation in their environment, HSPs may …
Energetic Nanoparticles As Fuel Additives For Enhanced Performance In Propulsion Systems, Srinibas Karmakar
Energetic Nanoparticles As Fuel Additives For Enhanced Performance In Propulsion Systems, Srinibas Karmakar
LSU Doctoral Dissertations
Biofuels are currently being explored as a carbon-neutral fuel alternative to petroleum-based fuels. However, biofuels such as ethanol has lower energy density (~27MJ/kg) relative to petroleum fuels (~ 45 MJ/kg). Adding high-energy density particles (such as boron with heating value of ~ 58.5 MJ/kg) to biofuels can generate fuel slurry with higher energy density than the base fuel, and represents a potential strategy toward making biofuels more viable. However, the combustion of boron is inhibited (specifically, the ignition is delayed) by the initial presence of an oxide layer, and its high evaporation and boiling temperatures. The present study investigates the …
Graham's Variety And Perverse Sheaves On The Nilpotent Cone, Amber Russell
Graham's Variety And Perverse Sheaves On The Nilpotent Cone, Amber Russell
LSU Doctoral Dissertations
In recent work, Graham has defined a variety which maps to the nilpotent cone, and which shares many properties with the Springer resolution. However, Graham's map is not an isomorphism over the principal orbit, and for type A in particular, its fibers have a nice relationship with the fundamental groups of the nilpotent orbits. The goal of this dissertation is to determine which simple perverse sheaves appear when the Decomposition Theorem for perverse sheaves is applied in Graham's setting for type A, and to begin to answer this question in the other types as well. In Chapter 1, we give …
Assessing Intention Of Volunteers To Develop Their Leadership: Creation Of An Instrument Using The Theory Of Planned Behavior, Janina Marie Fuller
Assessing Intention Of Volunteers To Develop Their Leadership: Creation Of An Instrument Using The Theory Of Planned Behavior, Janina Marie Fuller
LSU Doctoral Dissertations
During the current tough economic times volunteers are playing an increasingly important role in making human services widely available and in building collaborative community partnerships. Volunteers are most likely to be productive, to be satisfied with their experience, and to sustain their volunteer service when the opportunities provided to them are aligned with their motives for volunteering, which may include building the kinds of knowledge, skills, and interpersonal awareness that are the cornerstones of leadership. Organizations that purposefully recognize, support, and develop their volunteers’ leadership potential generate positive outcomes not only for themselves and their volunteers, but also for the …
Design And Analysis Of Cloaked Fluorophores For Rapid Detection And Visualization Of Cancer Cells Containing Nad(P)H:Quinone Oxidoreductase-1, William Silvers
Design And Analysis Of Cloaked Fluorophores For Rapid Detection And Visualization Of Cancer Cells Containing Nad(P)H:Quinone Oxidoreductase-1, William Silvers
LSU Doctoral Dissertations
The development of fluorogenic substrates for real-time tumor cell detection has led to a vastly expanding field for personal oncology. Fluorophores have been studied as appendages to larger scaffolds leading to accumulation of these dyes in tumor cells or their surrounding environment, taking advantage of tumor anatomy. A new class of fluorophores has been developed in which the dye is an active participant in the mechanism of cancer cell detection. These dyes have been conjugated such that their fluorescence has been eliminated or altered and will undergo a change to reveal their fluorescent signal upon activation by a mechanism that …
An Investigation Into Urban Elementary Teachers' Educational Beliefs In Regards To Teaching Writing: Comparing Experiences And Self-Reported Beliefs To Teacher Practices, Shalanda Stanley
LSU Doctoral Dissertations
This six week study investigated six urban elementary teachers’ educational beliefs in regards to teaching writing, comparing their personal histories as writers with their self-reported beliefs on writing and teaching writing, with that of their teacher practices. A further analysis examined how closely aligned their teacher practices were to research-validated practices. During this ethnographic case study, three questions were explored. These questions were: (a) How do teachers’ personal histories with writing inform their beliefs regarding writing in general, as well as their beliefs on teaching writing?, (b) How do teachers’ educational beliefs in regards to teaching writing inform their instructional …
Identification And Incorporation Of Quantitative Indicators Of Ecosystem Function Into Single-Species Fishery Stock Assessment Models And The Associated Biological Reference Points, Melissa Hedges Monk
Identification And Incorporation Of Quantitative Indicators Of Ecosystem Function Into Single-Species Fishery Stock Assessment Models And The Associated Biological Reference Points, Melissa Hedges Monk
LSU Doctoral Dissertations
The move towards an ecosystem approach to fisheries management requires baseline information on the biotic communities and an understanding of the interactions among species. The two objectives of this study were to describe the demersal fish community (DFC) associated with the northwestern Gulf shrimp trawl fishery, and to utilize a multispecies Lotka-Volterra model to examine possible community level effects of fishing. Community level effects include predator-prey interactions and the responses of fish in the same community to fishing pressure. The summer and fall Southeast Area Monitoring and Assessment Program (SEAMAP) bottomfish trawl surveys were used to identify spatial and temporal …
Principals Matter- Principal Technology Proficiency: Creating A Culture Of Technology Competence, Tiffanye Renee' Mccoy-Thomas
Principals Matter- Principal Technology Proficiency: Creating A Culture Of Technology Competence, Tiffanye Renee' Mccoy-Thomas
LSU Doctoral Dissertations
The primary purpose of this study was to investigate the role of leadership in developing a culture of technology competence within a school. Additionally, because research identifies the significance instructional leadership has on school performance, as defined by student achievement, the study sought to examine the impact principal technology proficiency has on school performance. To examine the associations amongst variables regression analyses were conducted. Quantitative study was conducted with 150 school principals and their faculties. Results indicated a strong correlation between principals that were technologically proficient, as defined by the Louisiana Department of Education’s Administrator Self-Assessment, and the percentage of …
The Role Of Atypical Semantic Activation In Schizotypy: Implications For Odd Speech And Creativity, Kyle S. Minor
The Role Of Atypical Semantic Activation In Schizotypy: Implications For Odd Speech And Creativity, Kyle S. Minor
LSU Doctoral Dissertations
Individuals with schizophrenia tend to demonstrate patterns of atypical semantic activation, which are characterized by increased activation of weakly associated words within the semantic network. Although atypical semantic activation is associated with formal thought disorder, tangential speech, and poor long-term functioning in schizophrenia, very little is known about this variable in individuals with schizotypy, or the 10% of the population who demonstrate personality traits presumed to reflect genetic liability to schizophrenia. In this project, we employed highly sensitive laboratory procedures to test whether individuals with schizotypy (n = 45) display increased atypical semantic activation compared to a non-schizotypy group (n …
Effects Of Hurricanes And Fires On Understory Hardwoods In Pine Savannas, Darin Ellair
Effects Of Hurricanes And Fires On Understory Hardwoods In Pine Savannas, Darin Ellair
LSU Doctoral Dissertations
Disturbance is important in maintaining the open structure of savannas. Frequent fires (every 1-3 years) limit the growth of woody plants, and prevent the transition from savanna to forest by maintaining open space for grasses, herbs, and fire-tolerant longleaf pine. Fires are not the only disturbances in southeastern pine savannas, which also experience hurricanes. Hurricane winds mainly affect the overstory, causing treefalls, increasing light, and adding litter to the understory. Hurricane effects were documented after Hurricane Gustav in 2008. More trees fell where the overstory was present, and produced localized effects on the ground below. Increase in light transmittance was …
Advanced Ceramics And Composites Based On Rice Hulls, Peigen Zhang
Advanced Ceramics And Composites Based On Rice Hulls, Peigen Zhang
LSU Doctoral Dissertations
As a by-product of the agricultural industry, rice hulls are available at large volume across the world. The disposal of the rice hulls itself is a big problem for the rice millers where the rice paddies are peeled off and rice hulls are produced. There have been many disposal methods developed, but the true value of the rice hulls would be more appreciated when they are employed to produce high value-added advanced ceramics. In this dissertation, advanced ceramics, such as AlN nanowires, SiC whiskers, mullite and SiC/Al2O3 nano-sized composites, were developed and studied based on the rice hulls. The SiC …
A New Model For Coalition Formation Games, Alfred Samman
A New Model For Coalition Formation Games, Alfred Samman
LSU Doctoral Dissertations
We present two broad categories of games, namely, group matching games and bottleneck routing games on grids. Borrowing ideas from coalition formation games, we introduce a new category of games which we call group matching games. We investigate how these games perform when agents are allowed to make selfish decisions that increase their individual payoffs versus when agents act towards the social benefit of the game as a whole. The Price of Anarchy (PoA) and Price of Stability (PoS) metrics are used to quantify these comparisons. We show that the PoA for a group matching game is at most kα …
Development Of Innovative Stationary Phases For Chiral And Protein Separations In Open Tubular Capillary Electrochromatography, Leonard Moore, Jr.
Development Of Innovative Stationary Phases For Chiral And Protein Separations In Open Tubular Capillary Electrochromatography, Leonard Moore, Jr.
LSU Doctoral Dissertations
Protein biomarkers in bodily fluids can lead to an indication of the onset of a disease. Due to low abundance of the biomarker at early stages of the disease and other protein interferences, detection may be challenging. Therefore, in order to achieve more selective protein separations, the development of a novel stationary phase has been investigated. Moreover, novel methods to apply polysaccharides as stationary phases were developed for protein separations as well as chiral separations. The initial discussions in this dissertation commences with the use of novel zwitterionic lysine-based molecular micelles as a coating for open tubular capillary electrochromatography (OT-CEC) …
Invasion Of Smooth Brome Into North American Tall-Grass Prairies: Impact On Native Plant/Herbivore Species And Mechanisms Responsible For Successful Invasion, Forrest Paul Dillemuth
Invasion Of Smooth Brome Into North American Tall-Grass Prairies: Impact On Native Plant/Herbivore Species And Mechanisms Responsible For Successful Invasion, Forrest Paul Dillemuth
LSU Doctoral Dissertations
Research in invasion ecology has focused on developing ecological theory that can predict how invasive species interact with invaded communities. However, empirical support for theoretical predictions has been inconsistent. Inconsistencies may be attributed to the lack of data in three core areas; (1) field data with enough resolution to determine population dynamics of invasive species in relation to native species, (2) manipulative field experiments that encapsulate natural variation found among micro-habitats, and (3) field data that incorporate effects of invasive species within and among spatial scales. This dissertation has addressed these concerns by examining the mechanisms responsible for the successful …
The Effect Of Test Design On Student Motivational Strategies For Learning And Student Retention, Jeanne Carol Samuel
The Effect Of Test Design On Student Motivational Strategies For Learning And Student Retention, Jeanne Carol Samuel
LSU Doctoral Dissertations
Large numbers of students attending community college lack essential college success skills (motivation and study strategies). Many of these students do not complete their degree programs. Identifying learning and teaching methods that promote the development of lifelong learning skills in addition to content acquisition is essential. This quasi-experimental research design study examined the effect of alternative multiple-choice question design on student motivational strategies for learning and retention. Participants were 59 students enrolled in a Microsoft® Office applications course at a public gulf coast community college. The discrete-option multiple-choice (DOMC) test was designed to limit cheating and guessing on tests. The …
China's 20th Century Sophist: Analysis Of Hu Shi's Ethics, Logic, And Pragmatism, Rya Butterfield
China's 20th Century Sophist: Analysis Of Hu Shi's Ethics, Logic, And Pragmatism, Rya Butterfield
LSU Doctoral Dissertations
This is a study of the theory of critical Sophistic logic that underwrote Hu Shi’s involvement in China’s 20th century reform period known as the Chinese Renaissance. Hu Shi was a radical liberal reformer who played a leading role in the New Culture Movement. He pursued a two-pronged project for cultural reform. One side of the reform was focused on developing a critical pragmatic logical theory. This side was aimed at the intellectual class and appealed to the heritage of the Confucian literati. The other side of the reform was focused on lifting the people’s vernacular language from vulgarity to …
Projected Performances: The Phenomenology Of Hybrid Theater, David Edward Coley
Projected Performances: The Phenomenology Of Hybrid Theater, David Edward Coley
LSU Doctoral Dissertations
Throughout the 20th century, mediatized forms gained prominence and eclipsed the theater as a site of cultural power and popularity. Because of this tension, performance theorists like Peggy Phelan framed the definition of theater through its inherent differences from film and television. Other theorists like Philip Auslander problematized this distinction, particularly due to television’s similarities to live performance. The cinema, however, has remained an opponent to performance, ignored in favor of technologies that more readily promote a sense of “liveness.” In Projected Performances, I argue that film projection is more closely related to performance than previously thought, particularly when viewed …
Conformance Testing Of Peer-To-Peer Systems Using Message Traffic Analysis, John Wesley Burris
Conformance Testing Of Peer-To-Peer Systems Using Message Traffic Analysis, John Wesley Burris
LSU Doctoral Dissertations
Peer-to-Peer architectures are used by a large number of distributed systems; however, the challenges such as maintaining a reliable and stable peer-to-peer network can make such networks undesirable for distributed systems. Peer-to-peer architectures are designed to be executed on systems with diverse hardware configurations, distant geographic locations, and varied, unpredictable Internet connectivity that make the software testing process difficult. This research defines a method for conformance testing peer-to-peer content distribution systems called “Method for Conformance Testing by Analyzing Message Activity” (MCTAMA). MCTAMA uses a common representation for describing the behavior of nodes during both design and deployment. ATAMA generates, evaluates …
The Common Struggle: Locating The International Connections Of National Spaces Of Conflict In The Francophone World, Mark Huntsman
The Common Struggle: Locating The International Connections Of National Spaces Of Conflict In The Francophone World, Mark Huntsman
LSU Doctoral Dissertations
In their 2007 manifesto, Quand les murs tombent: l’identit&236; nationale hors-la-loi, &200;douard Glissant and Patrick Chamoiseau propose that the nation-state is a stumbling block to global solidarity as it emphasizes cultural division. In order to achieve international community across borders, people must find common bonds that link them across traditional lines of conflict. My thesis applies this notion within the context of la Francophonie, an organization that has struggled with its goal of cultural rapprochement as its member nations continue to perceive each other as foreign entities rather than as like components of a larger community. I assert that la …
Examination Of The Reliability And Validity Of A New Observation Measure For Autism Spectrum Disorders: The Autism Spectrum Disorder Observation For Children, Daniene Neal
LSU Doctoral Dissertations
With increasing attention being drawn to autism spectrum disorders (ASD), specifically with regard to early and accurate diagnosis and treatment, researchers and clinicians alike have placed emphasis on finding assessment tools that can aid in this goal. The purpose of this study is to examine the psychometric properties of a new observation measure for ASD, the Autism Spectrum Disorders-Observation for Children (ASD-OC). The ASD-OC was found to have good to excellent interrater reliability, and excellent internal consistency (ƒÑ = .96). As a result of these initial reliability analyses, nine items were removed from the scale. The resulting 45 item ASD-OC …

The Responsibility Of Clothing Slaves In The United States As Described In Slave Petitions, 1775 To 1867, Ryan Jerel Aldridge
LSU Doctoral Dissertations
The content analysis of eighteenth and nineteenth century slave petitions identified slave dress terms and descriptors by type and frequency and a descriptive analysis of slave dress petitions revealed the following themes: the expense and burden attributed to clothing slaves, slave dress neglect, hiring contracts that included slave dress, the use of slave dress as a reflection of the slaveholders character, compensation for slave dress provided by an individual other than the slaveholder, the quality of slave dress, the distribution of slave dress, and slave dress terminology descriptors. The most frequent specific provision request for slave dress items consisted of …
Factors Affecting Short-Term Oxygen Variability In The Northern Gulf Of Mexico Hypoxic Zone, Brenda Leroux Babin
Factors Affecting Short-Term Oxygen Variability In The Northern Gulf Of Mexico Hypoxic Zone, Brenda Leroux Babin
LSU Doctoral Dissertations
Open-water continuous monitoring of DO concentrations at a single station (C6) in the Gulf of Mexico from 1989 to 2008 afforded an excellent opportunity to characterize short-term oxygen variability and to estimate the relative importance of key physical and biological factors controlling the development, persistence, and dissipation of hypoxia. I investigated temporal trends in three aspects of short-term DO variability: respiration rates (i.e., how quickly bottom waters become hypoxic), persistence of hypoxia, and the dissipation of hypoxia (i.e., re-aeration events). I identified the range of respiration rates present at the study site, and showed how these rates vary throughout the …

Geometrical And Electronic Structure Of Metal Oxide Nanoparticles On Silica And Alumina, Udaya Indike Rodrigo
Geometrical And Electronic Structure Of Metal Oxide Nanoparticles On Silica And Alumina, Udaya Indike Rodrigo
LSU Doctoral Dissertations
Recent studies demonstrated nanometer-scale combustion-generated nanoparticles cause demonstrable health effects. It is essential to understand the chemical characteristics of these nanoparticles. Since combustion-generated nanoparticles arise in complex mixtures, we employed a dendrimeric method to generate simpler, more reproducible nanoparticles, which were tethered to fumed silica and alumina to provide surrogates for fly ash. We collected XANES and EXAFS data, which are useful for characterizing disordered mixtures where the metal is a minor component. The effect of particle size on structural properties was studied with copper oxide nanoparticles on fumed silica. XANES data demonstrated copper atoms in the nanoparticles are present …
