Investigating The Role Of Genetic Variation In Long Run Economic Outcomes, Charles Justin Cook
Investigating The Role Of Genetic Variation In Long Run Economic Outcomes, Charles Justin Cook
LSU Doctoral Dissertations
This dissertation empirically tests whether adaptations resulting from the Neolithic Revolution, or the widespread adoption of sedentary agriculture for sustenance, have led to economic differences. The development of sedentary agriculture constituted an environmen- tal shift from the previous sustenance method of hunting and gathering. This environmental shift resulted in the natural selection of certain traits. I seek to exploit differences in these traits to measure differing economic outcomes. Two main adaptations are considered in this work: the ability to consume milk, or lactose tolerance, and resistance to infectious Eurasian diseases, which is the result of genetic variation. The first essay …
How Core Symptoms Of Autism Spectrum Disorder Predict Engagement In Specific Topographies Of Challenging Behavior, Sara Mahan
LSU Doctoral Dissertations
Challenging behavior, such as aggression, destructive behavior, and self-injurious behavior (SIB), are common among people of all ages with Autism Spectrum Disorder (ASD). Numerous researchers have found that greater severity of ASD or a diagnosis of ASD is significantly correlated with greater levels of challenging behavior. However, there is dearth of information on how core symptoms of ASD (i.e., socialization deficits, communication deficits, stereotypies) predict the engagement of specific topographies of challenging behavior above and beyond other variables, such as developmental functioning. The purpose of this study is to extend the current literature base through examining how core symptoms of …
A Numerical Investigation Of Apéry-Like Recursions And Related Picard-Fuchs Equations, Maiia J. Bakhova
A Numerical Investigation Of Apéry-Like Recursions And Related Picard-Fuchs Equations, Maiia J. Bakhova
LSU Doctoral Dissertations
In this work we investigate a generalization of a recursion which was used by Apery in his proof of irrationality of the zeta function values at 2 and 3. It is a continuation of the work of Zagier , who considered generalization of the first equation and numerically investigated it. The study is made for two generalizations of the second equation, one used the mirror symmetry idea from the theory of Calabi-Yau varieties and another worked with recursion. There were discovered connections between them.
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). …

LSU Doctoral Dissertations
The purpose of this qualitative case study was to ascertain how music-making and band membership contributed to the identities of members of the New Orleans Concert Band and how their identities influenced their behaviors. The musician role identity of members of the New Orleans Concert Band, an adult community band, was examined through the lens of identity theory using ethnographic methods. Findings were based upon interviews with 37 band members, observations of rehearsals and concerts, and an examination of the organization’s documents. Results indicated that members valued individual and group music-making, literature played by the band, and social aspects of …
Applicability Of Periodization To Orchestral Audition Preparation On Trombone: A Case Study, Christopher Evan Green
Applicability Of Periodization To Orchestral Audition Preparation On Trombone: A Case Study, Christopher Evan Green
LSU Doctoral Dissertations
The process of auditioning can seem daunting because of the high standards of performance required to win. Brass players have a finite amount of time they can practice each day because of the small muscles of the embouchure. Despite the vast amount of information available on preparing for a brass orchestral audition, little has been written on how to organize a practice schedule leading up to the audition. An analysis of literature in the major brass journals confirm which strategies have been considered to be most important when preparing for an audition, but an important component from the world for …
Performing Nostalgia: Body, Memory, And The Aesthetics Of Past-Home, Jade C. Huell
Performing Nostalgia: Body, Memory, And The Aesthetics Of Past-Home, Jade C. Huell
LSU Doctoral Dissertations
Since its etymological beginnings, the meanings and usages of nostalgia have shifted markedly. In the shifting, nostalgia’s associations with the body and with the concept of home has diminished. This study of African American nostalgia for Africa uses genealogical inquiry, personal and autoethnographic narrative, and performance theories and practices to reinvigorate the relations between body, memory, aesthetics, past, and home. Attending to operations of time and space, I theorize the aforementioned relations in order to build a theory of critical nostalgia. Following Debbora Battaglia, I argue and illustrate that nostalgia is an act realized in performance, and I develop my …

In the first part of the research, we investigated the torque that develops when faceted nanoparticles, namely cubes and …
A Thermodynamic Framework For The Modeling And Optimization Of Crystallization Processes, David John Widenski
A Thermodynamic Framework For The Modeling And Optimization Of Crystallization Processes, David John Widenski
LSU Doctoral Dissertations
Crystallization is a widely used chemical engineering separation unit operation process. Since this technique can produce high purity products it is used for the industrial production of many chemical compounds, such as pharmaceuticals, agrochemicals, and fine chemicals. The production of these products is a multi-million dollar industry. Any methods to improve the production of these products would be highly valued. Thus, the main objective of this work is to target model-based optimal strategies for crystallization operations specifically targeting crystal size and crystal size distribution (CSD). In particular, take the knowledge gained and translate it into an economically and practically feasible …

Total Synthesis Of A Virotoxin And Analogs For Conformational Studies, Benson Jumba Edagwa
LSU Doctoral Dissertations
This dissertation describes the first total synthesis of alloviroidin in trace amounts, along with that of three analogs containing L-proline (Pro), trans-3-hydroxyproline (3-Hyp) or cis-4-hydroxyproline (4-hyp) residue substituting for 2,3-trans-3,4-trans-dihydroxyproline in the natural product. We report herein an efficient strategy that provides a dipeptide containing a (2S,4S)-4,5-dihydroxyleucine (dihyLeu) residue, including a diastereoselective dihydroxylation. Nα-Carbobenzyloxy-(2S)-4,5-dehydroleucine was coupled with valine ethyl ester to give a dipeptide that was subjected to a Sharpless asymmetric dihydroxylation to introduce the diol. The relative configuration at C4 was assigned as S by X-ray crystallography after derivatization as an α-amino-γ-lactone hydrochloride salt. The preparation of the 2-(methylsulfonyl)tryptophan …
Fatigue Performance Of Existing Bridges Under Dynamic Loads From Winds And Vehicles, Wei Zhang
Fatigue Performance Of Existing Bridges Under Dynamic Loads From Winds And Vehicles, Wei Zhang
LSU Doctoral Dissertations
During the life cycle of bridges, varied amplitude of stress ranges on structural details are induced by the random traffic and wind loads. The progressive deteriorated road surface conditions might accelerate the fatigue damage accumulations. Micro-cracks in structural details might be initiated. An effective structural modeling scheme and a reasonable fatigue damage accumulation rule are essential for stress range acquisitions and fatigue life estimation. The present research targets at the development of a fatigue life and reliability prediction methodology for existing steel bridges under real wind and traffic environment with the capability of including multiple random parameters and variables in …
Income Inequality And Mortality: A Test Of Competing Pathways, Lisa Winters
Income Inequality And Mortality: A Test Of Competing Pathways, Lisa Winters
LSU Doctoral Dissertations
Findings from numerous studies indicate that individuals living in more unequal societies are at greater risk for a variety of health problems. However, questions remain about the possible pathways that link health outcomes and income inequality. In general, the debate about how income inequality affects individual health centers around two issues: 1) whether the relationship is representative of the level of social cohesion within a given area, and/or 2) whether it is more indicative of the level of local investment in public health infrastructure. Each of these theories, then, represents a potential mediating mechanism through which income inequality impacts individual …
Exploring The Influence Of Civic Community Structures On Family Poverty In A Multilevel Context, Candice A. Myers
Exploring The Influence Of Civic Community Structures On Family Poverty In A Multilevel Context, Candice A. Myers
LSU Doctoral Dissertations
This dissertation integrates the civic community perspective and structuralist and individualist perspectives of poverty to assess the relationships between civic community structures and family poverty outcomes. The key contribution of this project to the larger bodies of civic community and poverty research is the use of a multilevel framework that accounts for both community context and family characteristics in shaping family poverty outcomes. This objective is carried out through a series of multilevel analyses wherein religious and economic civic community structures are examined in relation to various conceptualizations of family-level poverty. The first analysis examines the associations between religious-based measures …
Amd&Art: Performativity And Participation In Ecological Remediation, Travis Paine Brisini
Amd&Art: Performativity And Participation In Ecological Remediation, Travis Paine Brisini
LSU Doctoral Dissertations
In this study, I examine and theorize AMD&ART, an artwork devoted to treating polluted water in Vintondale, PA. AMD&ART is much more than simply a water treatment facility, however. Each chapter of this document examines AMD&ART through the lens of a different body of scholarly literature: the literature associated with land art, Systems Theory, Network Theory, Companion Specieshood and others. The theoretical focus of this paper is the emergent importance of the concept of performativity—“that reiterative power of discourse to produce the phenomena that it regulates and constrains” (Butler, Bodies 2)—in the deconstruction of the binary division of “nature” and …
How Faith And Leadership Are Connected: A Study Of Catholic Women Administrators In A Southern Public Institution Of Higher Education, Mary Blanchard Wallace
How Faith And Leadership Are Connected: A Study Of Catholic Women Administrators In A Southern Public Institution Of Higher Education, Mary Blanchard Wallace
LSU Doctoral Dissertations
Studies concerning spirituality and higher education, particularly for the college student, are beginning to appear in journals, conference papers, and presentations. However, there is little research conducted with professionals in higher education on the construct of spirituality. Spirituality has so many different definitions in the literature, it is difficult to define, and perhaps even more complex to study academically. Using a research-based conceptual model for religious faith, developed within the study of family sciences, this study examines the lived experience of how and why Catholic women administrators connect their faith and leadership in a setting of public institutions of higher …

Children's Representations Of Parenting Behaviors, Basic Negative Emotions, And Negative Self-Conscious Emotions In The Narrative Story Stem Technique, Loredana Apavaloaie
LSU Doctoral Dissertations
The current study examined middle childhood aged Romanian children’s representations of parenting behaviors, basic negative emotions, and negative self-conscious emotions in the Narrative Story Stem Technique (NSST; Bretherton, Ridgeway, & Cassidy, 1990). More specifically, the research objectives of the study were a) to identify the frequency of the representations that were reflected in children’s narratives, b) to identify the specific stories that elicited the greatest number of representations, c) to identify possible relationships among children’s representations, their age, and amount of time that parents spend with their children, d) to identify gender differences in representations, and e) to evaluate the …
Copper-Cobalt Catalysts For Conversion Of Syngas To Ethanol And Higher Alcohols, Miranda Louise Smith
Copper-Cobalt Catalysts For Conversion Of Syngas To Ethanol And Higher Alcohols, Miranda Louise Smith
LSU Doctoral Dissertations
Higher alcohols produced by catalytic conversion of synthesis gas are potential octane enhancers for transportation fuels. Copper-cobalt catalysts have emerged as alternatives to the ethanol-selective, but expensive, rhodium-based ones. The reducibility of the catalyst and the CO adsorption mode are important factors in directing the selectivity of CO hydrogenation toward methanol, hydrocarbons, or higher alcohols. In this study, Cu/SiO2, Co/SiO2, and bimetallic CuCo/SiO2 catalysts, as well as their tin-promoted analogues, were synthesized and characterized by TPR, in situ XRD, in situ XANES, and in situ DRIFTS. Cobalt addition to Cu/SiO2 created an amorphous fraction of CuO that was more easily …
Biomass Energy Production In Louisiana: A Gis Study On The Supply Chain, Anil Raj Kizhakkepurakkal
Biomass Energy Production In Louisiana: A Gis Study On The Supply Chain, Anil Raj Kizhakkepurakkal
LSU Doctoral Dissertations
One major drawback of biomass fuel is its bulky nature and the resulting high cost of transporting the fuel to the facility where the energy is being produced. Hence, supply chain of biomass residues plays a crucial role in determining the financial viability of bioenergy production. Transporting biomass for energy purposes more than 50 miles (80 km) is not considered economically feasible in most conditions. In the wood energy scenario, the maximum distance is more often restricted to distances of less than 200 km between production and consumption (via road). A study was done to determine logging residues and agricultural …
Queer Utopian Geographies And Cold War Poetry, Brigitte Natalie Mccray
Queer Utopian Geographies And Cold War Poetry, Brigitte Natalie Mccray
LSU Doctoral Dissertations
Queer Utopian Geographies and Cold War Poetry intervenes in the general narrative about Cold War culture, made even more famous by such recent popular shows like Mad Men and Pan Am, that describes the era as a repressed society in desperate need of liberation. While indeed Cold War America was a time of paranoia and loyalty oaths, even before the Stonewall Riots of 1969 gay men and lesbians found subtle ways to resist popular media and government discourse that perpetuated the myth that the homosexual was the anti-citizen. A number of gay men and lesbians traveled extensively to escape this …
Subgradient Formulas For Optimal Control Problems With Constant Dynamics, Lingyan Huang
Subgradient Formulas For Optimal Control Problems With Constant Dynamics, Lingyan Huang
LSU Doctoral Dissertations
In this thesis our fi_x000C_rst concern is the study of the minimal time function corresponding to control problems with constant convex dynamics and closed target sets. Unlike previous work in this area, we do not make any nonempty interior or calmness assumptions and the minimal time functions is generally non-Lipschitzian. We show that the Proximal and Fréchet subgradients of the minimal time function are computed in terms of normal vectors to level sets. And we also computed the subgradients of the minimal time function in terms of the F-projection. Secondly, we consider the value function for Bolza Problem in optimal …

Examination Of The Relationship Between Specific Classes Of Social Skill Behaviors And Academic Competence On The Social Skills Improvement System Rating-Scales, Michael James Vance
Examination Of The Relationship Between Specific Classes Of Social Skill Behaviors And Academic Competence On The Social Skills Improvement System Rating-Scales, Michael James Vance
LSU Doctoral Dissertations
An individual’s social competencies and interpersonal relationships have been repeatedly linked to a number of behaviors not typically directly associated with social skills including depression (Hokanson & Rupert, 1991) and aggressive behavior (McColloch & Gilbert, 1991). In addition to these more social behaviors, social skills have also been shown to be predictive of both risk and protective factors related to academic functioning (Newcomb, Bukowski, & Pattee, 1993; Parker & Asher, 1987). The current study aims to add to the literature by examining the relationship between teacher, parent, and self-ratings of specific classes of social skill behaviors and teacher ratings of …
Thermal Field Investigations And Applications To Integral Abutment Bridges With Frp Panels, Bo Kong
Thermal Field Investigations And Applications To Integral Abutment Bridges With Frp Panels, Bo Kong
LSU Doctoral Dissertations
Expansion joints are often considered as one of the most vulnerable elements affecting the sustainability of traditional jointed bridges. Over the past several decades, a new type of integral abutment bridge (IAB) has been proposed, where the joints are eliminated at the abutments and/or along the length of the bridges. Although with wide acceptances, the IABs have not been largely applied in practice. Many arguments are unsettled and there are no national design guidelines currently. Among all, the thermal behavior is one of the most concerned issues, and that, to a large extent, limits the maximum length of IABs that …
Pressures, Centralization, Economics, Technology, And Ethics: Factors That Impact Public Information Officer - Journalist Relationships, Christopher Jon Mccollough
Pressures, Centralization, Economics, Technology, And Ethics: Factors That Impact Public Information Officer - Journalist Relationships, Christopher Jon Mccollough
LSU Doctoral Dissertations
A study of public information officers (PIOs) in three states and the journalists that cover state government finds five primary factors that shape the working relationships between both groups. Institutional pressures on both PIOs and journalists impact the ability of both parties to meet the needs of the other party on a daily basis. High levels of centralization in state government communication limit the ability of PIOs to meet the needs of journalists, fostering journalists’ antagonism and a more combative working relationship. The economic decline of journalism is creating a dichotomous situation where PIOs can help journalists manage increasing demands …

The Effect Of Video Self-Monitoring On Teaching Aba Paraprofessionals, Kristen Nicole Abbondante
LSU Doctoral Dissertations
This study examined the effects of psychoeducation method (video vs. manual) on the knowledge, attitudes, and beliefs of participants regarding the education of children with autism within a group design. There was not a significant difference between the two groups on the participants’ thoughts, attitudes, or knowledge. Study Two examined the effect of video self-monitoring on teaching paraprofessionals to implement discrete trial instruction with children with autism. A single-subject multiple baseline design across four participants was utilized. The participants were taught to use discrete trial instruction (DTI) using a video self-monitoring procedure. Results showed that performance feedback was necessary for …
Design, Synthesis, Characterization, And Application Of Peptides As Different Medical Treatment, Krystal Renee Fontenot
Design, Synthesis, Characterization, And Application Of Peptides As Different Medical Treatment, Krystal Renee Fontenot
LSU Doctoral Dissertations
A peptide is defined, as a molecule that contains less than fifty amino acids; anything larger is a protein. Peptides are important molecules because they have diverse uses. Peptides were utilized in two ways: 1) Peptide bioconjugates containing a fluorescent porphyrin or phthalocyanine macrocycle were designed and investigated, with or without a PEG moiety for selective targeting of the epidermal growth factor receptor (EGFR). 2) Amyloid aggregating mitigating peptides (AAMPs) was synthesized and investigated containing polar amino acids, MiniPEGs, and/or ααAAs that have the ability to inhibit and disrupt Amyloid Beta (Aβ). The peptide bioconjugates containing a porphyrin or phthalocyanine …
Efficacy Of Multifunctionalized Saccharide Constructs For The Attenuation Of Amyloid-Beta Toxicity, Dhruva Dilip Dhavale
Efficacy Of Multifunctionalized Saccharide Constructs For The Attenuation Of Amyloid-Beta Toxicity, Dhruva Dilip Dhavale
LSU Doctoral Dissertations
There is evidence that amyloid-beta (Aβ) toxicity is mediated through interactions and binding with neuronal surface sialic acids in Alzheimer’s disease (AD). The binding affinity is higher if the sialic acids are clustered and toxicity of Aβ was attenuated by removal of neuronal sialic acids. Thus, interfering with cell membrane-Aβ binding using biomimetics that could reproduce the clustered sialic acid structure could present us with a potential target for therapeutic intervention in AD. Based on this hypothesis, we developed several multifunctionalized sialic acid labeled chitosan compounds of different valency, or number of sialic acid per chitosan molecule, to attenuate Aβ …

The Decline In Trust In The European Union, Nathan Donald Price
The Decline In Trust In The European Union, Nathan Donald Price
LSU Doctoral Dissertations
After twenty years, the European Union is undoubtedly at a crossroads, as its institutions try to manage the sovereign debt crisis in member states and the uncertainty surrounding the future direction of the project. The challenges the European Union has faced, and the response to them, have drawn considerable attention on the capacity of the European Union to manage the interests of the Europeans. In this dissertation, I discuss the process of Europeanization and why it has resulted in suboptimal outputs. Additionally, I discuss the perception of a democratic deficit in the European Union. The purpose of this is to …
