Fillers are categorized according to their reactive properties alongside their physical attributes leading to active fillers strengthening bond formation …

Considering The Ethics Of Conserving American Art: White Nationalism And The Evolving Meanings Of Nineteenth-Century Genre And Landscape Painting, Evan M. Crocker

LSU Master's Theses

This thesis analyzes the stylistic and conceptual qualities of American genre and landscape painting from the antebellum period and how these qualities acted in service to establishing white nationalism before the Civil War. The intricate and calculated system of typing in genre painting presented carefully crafted idealizations of quintessential Americans, defined by their whiteness and maleness. Landscape painters of the early- to mid-nineteenth century endowed their compositions with a sense of wondrous opportunity which justified and upheld westward expansion under Manifest Destiny. At the intersection of genre and landscape practices sits plantation paintings—specifically house portraits—in which the plantation serves as …

From Decriminalization To Social Legitimization: The Lived Experiences Of Non-Conforming Individuals In India, Heeya Datta

LSU Doctoral Dissertations

This dissertation explores how queer and non-conforming individuals in urban India navigate, resist, and reimagine dominant norms of kinship, intimacy, and family. Drawing on 18 in-depth interviews, it examines the lived experiences of LGBTQ+ individuals in the aftermath of legal reforms such as the decriminalization of Section 377 and the Transgender Persons (Protection of Rights) Act. While these reforms mark symbolic progress, queer individuals continue to face social stigma, legal exclusions, and familial rejection. The study is divided into three chapters: the first analyzes the dual role of homosociality as both a space of refuge and constraint; the second investigates …

Enduring Words: Resistance Through Sculptural Libraries, Alex C. Jacobs

LSU Master's Theses

Enduring Words: Resistance Through Sculptural Libraries is a thesis exhibition that challenges book censorship by transforming reading into a public and defiant act. Through direct sculptural interventions, the exhibition confronts cultural erasure, questions who controls the literature we consume, and highlights the role of art in safeguarding contested knowledge. This thesis focuses on a current body of exhibited sculptural works that embody the tension between access and erasure. These installations engage with the viewer by using a lighthouse built of books and a speech-bubble-shaped library embedded with censored texts. They do not quietly mourn the suppression of knowledge; they confront …

Optimizing The Sustainability Of Asphalt Pavements Through Incorporating Crumb Rubber In High-Modulus Asphalt Concrete (Hmac) Mixtures In Louisiana, Heena Dhasmana, Marwa Hassan, Mohamed Abdelmageed

Publications

Asphalt mixtures are traditionally produced using the Superpave mix design method, which emphasizes volumetric properties; however, current research is shifting toward performance-based and sustainable approaches. Within this context, the French High Modulus Asphalt Concrete (HMAC) design focuses on achieving specific performance criteria for workability, stiffness, rutting resistance, and fatigue behavior, employing a hard binder with higher asphalt content and fewer air voids than Superpave mixes. In this study, HMAC mixtures were developed using crumb rubber and locally sourced Louisiana materials. Five HMAC mixes using PG 76-22 and PG 67-22 binders with 10% and 20% crumb rubber were prepared, along with …

Gendered Expectations: Do Voters Reward Women For Supporting Women's Interests?, Nichole M. Bauer, Anna Gunderson, Jeong Hyun Kim, Elizabeth Lane, Belinda Davis, Kathleen Searles

Faculty Publications

Are women legislators punished for not supporting women's substantive policy interests? We test these gendered expectations. We marshal an original content analysis of cable news coverage and two survey experiments testing voters' assessment of hypothetical legislators on the issues of abortion and equal pay. We find that voters rate both women and men legislators positively for supporting women's issues and negatively evaluate legislators of both genders when they do not support women's interests. We also find that women voters negatively evaluate women legislators who act against women's interests at a greater rate than men voters. While we do not find …

Estimating The Future Frequency Of Bonnet Carré Spillway Openings, Kayla Thomas

LSU Master's Theses

In the 2010s, the Bonnet Carré Spillway (BCS) in southeastern Louisiana, U.S.A., experienced an unprecedented uptick in openings to mitigate the possibility of flooding, including a record double-opening in 2019. Both the environmental consequences of BCS openings associated with nutrients that run from the Mississippi River into Lake Pontchartrain and the synoptic-scale meteorological conditions that necessitate these openings are poorly understood. With the unexpectedly frequent openings in recent years and the ever-present threat of climate change, it is vital to consider the future shift of synoptic-scale climate patterns and how it can relate to BCS openings. Understanding the potential for …

Proteomic Comparison Of Canine Gallbladder Versus Hepatic Neuroendocrine Neoplasms, Nadia Richmond

LSU Master's Theses

Hepatobiliary neuroendocrine neoplasms (HBNENs) are uncommon tumors in people and dogs, and the limited understanding of their biologic behavior often poses a diagnostic and prognostic challenge in the clinical setting. Though only a low number of cases have been described in dogs, there is evidence to indicate that primary gallbladder NENs may carry a more favorable prognosis compared to primary hepatic NENs. The emergence of liquid chromatography-mass spectrometry (LC-MS) in proteomic analysis has permitted large-scale analysis of neoplastic proteomes, allowing for better understanding of tumor pathophysiology while simultaneously enabling the rapid identification of protein biomarkers. Previous work in our laboratory …

Fishing For Solutions: Compensation For Bycatch Reduction In The Gulf Of Mexico Shrimp Fishery, Daniel W. Harris

LSU Master's Theses

Bycatch, unintentionally caught non-target species, harms the profitability of commercial fishing operations and leads to death and injury of hundreds of thousands of marine animals per year. In the Gulf of Mexico, commercial shrimpers are required to use a bycatch reduction device (BRD). Better BRDs are being tested to further reduce bycatch. Because their use will not be mandatory, it is important to measure shrimper willingness to voluntarily adopt this conservation technology to predict potential fleet participation. This study uses contingent valuation to elicit commercial shrimpers’ willingness to accept compensation for using these new devices.

We employ an incentivized payment …

Utilizing a qualitative case study methodology, we explored the perspectives of Uyghur youth athletes to gain insight into the challenges they face in achieving social inclusion without feeling “othered” or excluded. Data analysis followed an inductive grounded theory approach, identifying first‐order concepts, second‐order themes, and aggregate theoretical dimensions. Our findings reveal that social inclusion of Uyghur youth through sports participation is influenced by multiple factors, including language barriers, stereotypes, cultural differences, high expectations, and government policies. …

A Natural Short Sleep Mutation Promotes Longevity Through Mitochondrial Respiration In Drosophila, Pritika Pandey

LSU Doctoral Dissertations

Aging is an irreversible process characterized by progressive physiological decline and an increased risk of metabolic disorders, cognitive impairment, cardiovascular diseases, and neurodegeneration. Disruptions to the circadian clock—whether due to genetic mutations or behavioral factors—accelerate aging and age-related pathologies, highlighting a strong link between circadian regulation and longevity. However, certain individuals harbor a dec2^P384R mutation, which enables natural short sleep without the detrimental effects of chronic sleep deprivation. This suggests that these individuals have evolved adaptations that activate pro-health pathways, allowing them to function optimally with reduced sleep. To investigate the genetic mechanisms underlying these changes, we developed a …

Multiparticle Quantum Plasmonics: Fundamentals And Applications, Mingyuan Hong

LSU Doctoral Dissertations

Quantum plasmonics explores the interaction between light and collective charge oscillations at metal-dielectric interfaces, enabling strong light confinement and enhanced quantum effects at the nanoscale. While traditional quantum optics has primarily focused on single-photon systems, an intermediate regime exists between classical and single-photon optics - multiparticle (or multiphoton) quantum optics. In this regime, classical light sources, when analyzed through techniques such as photon-number-resolving (PNR) detection and projective measurement, can reveal nontrivial quantum correlations. This thesis investigates how multiparticle quantum plasmonics harnesses these correlations to control quantum statistical properties, enhance coherence, and enable novel applications in quantum technologies.

In this thesis, …

Stoicism As A Panacea For Contemporary Problems, Taiwo Oriyomi Akande

LSU Master's Theses

The contemporary world is battling with the persistent problems of racism and environmental crises that threaten human co-existence and constitute an existential threat in general. These pressing issues have led to injustice, disunity, and ecological destruction. Though human history has recorded some victories in the advancement of human rights and environmental policies yet, there are still some forms of racism that are entrenched in society's structure. Environmental degradation also continues due to the failure or limitation in policies meant to tackle it, and the unsustainably bad attitudes of humans toward the environment. This thesis argues that Stoicism, a philosophical tradition …

Faith And Freedom: The Role Of Religion In The Bishops' Wars, Christopher S. Jordan

LSU Master's Theses

Despite their overall importance to British history, the Bishops’ Wars (1639-1640) remain relatively obscure conflicts. They are more often studied and recognized in larger narratives, such as the English Civil War or the Covenanting movement in Scotland. Regardless, these wars perhaps deserve more attention in themselves to recognize their significance in their own time. While most historians and commentators on this war have noted the many political aspects and undertones of this conflict, which there are many, this thesis will examine the religious aspects and undertones and attempt to argue that religion that had the largest role in the start, …

Innovative Design Methodology For Durable Open-Graded Friction Course Asphalt Mixtures, Anas Abualia

LSU Doctoral Dissertations

Open-graded friction course (OGFC) is a thin asphalt mixture surface layer with a high percentage of coarse aggregates and high interconnected air voids, which provides improved skid resistance, visibility, and decreased pavement-tire noise. However, construction personnel at DOTD reported that conventional OGFC mixtures have short service life (raveling distress). Further, their structural contribution to the pavement structure is commonly neglected and designed only for functionality purposes.

The objective of this study was to develop a rational mix design methodology to improve the durability of OGFC asphalt mixtures. Specific objectives are to: (1) conduct a rheological and chemical characterization of polymer-, …

Metabolic Transitions In Embryos Of Artemia Franciscana: Regulation And Consequences For Oxidative Stress, Daniel Anthony Arabie

LSU Doctoral Dissertations

Embryos of Artemia franciscana survive harsh conditions in diapause and anoxia-induced quiescence for years by undergoing deep metabolic transitions. I investigated the relationship between phosphorylation of pyruvate dehydrogenase (PDH) and carbon flux to the tricarboxylic acid (TCA) cycle during metabolic depression. The difference in catalytic activity of the PDH complex (PDC) in maximally phosphorylated and dephosphorylated samples was 16.5-fold. Western blot analysis confirmed the changes in phosphorylation of PDH. Analysis of PDH expression in diapause and post-diapause embryos via phospho-PDH showed no significant differences. Investigation of post-diapause embryos under anoxia showed that phosphorylation of PDH decreased and activated the enzyme. …

Examining Whether Method Of Suicide Exposure And Closeness To Decedent Relate To Firearm Storage Practices, Evan A. Albury, Jessica L. Gerner, David A. Jobes, Raymond P. Tucker

Faculty Publications

Introduction: One factor that can influence whether someone will engage in secure firearm storage is having a suicide exposure (SE). Daruwala et al. (2018) examined this and found that individuals with an SE, without considering perceived closeness, did not significantly differ from those who did not have an SE in their firearm storage practices. Thus, the present study aimed to replicate and extend the research of Daruwala et al. (2018) by examining if the method of suicide (by firearm or other means) and closeness of suicide decedent relate to secure firearm storage practices. Methods: 308 male firearm owners completed self-report …

From Exit To Apathy: Migration, Remittances, And The Erosion Of Political Participation, Sanjida Mehrin

LSU Master's Theses

This thesis offers new perspectives on migration and political behavior in Latin America by analyzing how remittances affect political engagement and how economic perceptions influence migration intentions. While classic models focus on structural economic conditions, this study emphasizes the independent significance of subjective economic judgments as well as the different political implications of remittances across national contexts. The first chapter challenges traditional models that mainly link migration with objective economic indicators by examining how migration intentions are influenced by retrospective economic views. Using individual-level data from the 2018 LAPOP survey across 19 Latin American countries, the analysis employs country fixed …

Audience Participation Structures In The Concert Hall And D, Me, You, We, A Non-Opera For Actor, Chatbot, Musicians, And Audience, Treya Michelle Nash

LSU Doctoral Dissertations

Audience participation in the concert hall space has developed into a rich participatory practice with specific characteristics and challenges. Though composers—especially since the 1960s—have written many pieces involving audience participation, asking the concert hall audience to participate remains uncommon. Attempting to shift the role of the audience in such a traditionally spectator-oriented space can lead to tensions that undermine the efficacy of the experience. This research categorizes participatory pieces into the structural elements of performance and facilitation forces, audience groupings, audience roles, and communication types. These structures are used to discuss the complicated relationship between control and agency within participatory …

19ne Excited States In Explosive Nucleosynthesis, Khang Pham

LSU Doctoral Dissertations

Classical novae and Type I X-ray bursts are stellar explosions that occur in binary systems, where nuclear reactions involving ¹⁹Ne play a crucial role in nucleosynthesis. In novae, the destruction of ¹⁸F via the ¹⁸F(p,alpha)¹⁵O reaction significantly affects the amount of ¹⁸F remaining in the ejecta, directly influencing the detectability of predicted 511-keV gamma rays. However, discrepancies between observed and predicted ¹⁸F abundances highlight uncertainties in the reaction rates, primarily due to unknown properties of resonances in the compound nucleus ¹⁹Ne. In Type I X-ray bursts, the ¹⁵O(alpha,gamma)¹⁹Ne reaction …

Approximations Of Koopman Operator Semigroups, Ibrahem Al Jabea

LSU Doctoral Dissertations

The main purpose of this dissertation is to study approximation methods for nonlinear systems using Bernhard Koopman's Global Linearization Method or Sophus Lie's method of continuous transformation groups. This approach enables the application of linear semigroup methods to a nonlinear system by focusing on the dynamics of the observables of the states, rather than directly studying the dynamics of the states. In this dissertation, we studied the pointwise semigroup and introduce the modified space $C_m(\Omega)$ and the modified Koopman-Lie semigroups. We use a splitting operator and outline a systematic approach for approximating the pointwise Koopman-Lie semigroup flows \begin{equation*} t\to T(t)g(x) …

Optical Spring Tracking For Enhancing Quantum-Limited Interferometers, Scott M. Aronson

LSU Doctoral Dissertations

Gravitational waves were first predicted by Albert Einstein in 1916. Calculations in the 1970s by Rainer Weiss showed an interferometer of sufficient size could realistically detect gravitational waves, which led to a grant by the National Science Foundation (NSF). With steady progress and over decades of funding by the NSF, the construction of two full scale 4km interferometers was approved and began construction in 1994. This project, coined LIGO the Laser Interferometer Gravitational-wave Observatory, came to be a worldwide collaboration of scientists dedicated to the discovery and study of gravitational waves. In 2015, both LIGO detectors detected a coincident inspiral …

Assessing Groundwater Availability And Land Subsidence Risk Associated With Anthropogenic Activities In A Complex Aquifer System, Aya Bakr Attya Mohamed

LSU Doctoral Dissertations

The Southern Hills aquifer system (SHAS) is the primary source of water in the Capital area of Louisiana. However, the overexploitation of freshwater-bearing aquifers and the presence of two active faults, the BR fault and the DSS fault, have resulted in groundwater depletion, saltwater intrusion, and increased the risk of land surface subsidence. Such critical issues pose substantial threats to groundwater availability and exert detrimental effects on the environment and urban infrastructures. This dissertation presents a comprehensive investigation of the SHAS for recognizing the consequences of groundwater depletion and its potential long-term impacts on groundwater availability and land stability. A …

Studies On Cell Cycle Regulation And Ecm Modification During Tubular Organ Formation In Drosophila Embryos, Jeffrey Matthew

LSU Doctoral Dissertations

The formation of tubular organs—such as the heart and kidneys—is a complex developmental process that requires the precise coordination of tissue remodeling with dynamic changes in cellular behavior. Key processes including cell proliferation, apoptosis, and extracellular matrix (ECM) formation must be tightly synchronized with mechanisms that generate and transmit physical forces, transforming a flat epithelial sheet into a three-dimensional organ. Disruptions in the homeostasis of these processes during organogenesis can lead to congenital defects, such as pulmonary atresia and renal hypoplasia.

To investigate the mechanisms underlying epithelial morphogenesis, the Chung laboratory employs the Drosophila embryonic salivary gland (SG) as a …

Adverse Childhood Experiences And High School Dropout: The Roles Of Student Disengagement And Social Support, Rachel D. Pounders

LSU Doctoral Dissertations

More than two million students a year leave high school without a completion credential (NCES, 2024). Students who drop out are at-risk for detrimental long-term outcomes physically, mentally and economically (Rumberger, 2020). Students with adverse childhood experiences (ACEs) are significantly more likely to have poor educational outcomes, including school dropout (Metzler et al., 2017; Pan et al., 2019). However, there is limited insight into what affects the pathway between ACEs and poor educational outcomes for students (Dupéré et al., 2019; Morrow & Villodas, 2018). Informed by prominent dropout theories with ecological foundations and the theory of stress and coping, this …

On Regularity And Convergence Of Solutions To The Boltzmann-Enskog Equations, Christian Ennis

LSU Doctoral Dissertations

The Boltzmann equation describes the time evolution of the density function in position-velocity space for a classical particle subjected to possible collisions by other particles in a diluted gas that expands in vacuum for a given initial distribution. While many authors have studied the probabilistic interpretation of the spatially homogeneous Boltzmann equation, there is a dearth of articles on the stochastic framework of the full (that is, spatially inhomogeneous) Boltzmann equation. In this thesis, we examine a stochastic process, developed by S. Albevario, B. Ruediger, and P. Sundar, whose law is a weak solution to a mollified Boltzmann equation. This …
