Deciphering And Translating Bioinspired Structures For Engineering Materials Design Via Computational Modeling And Machine Learning, Zhangke Yang

All Dissertations

Nature has evolved extraordinary structural materials—such as nacre, bone, and the mantis shrimp’s dactyl club—that achieve remarkable combinations of strength, toughness, and impact resistance. These properties arise from sophisticated synergies between structure and composition. Inspired by these biological systems, this dissertation presents a comprehensive investigation into bioinspired materials, uncovering fundamental mechanisms and providing guidance on designing materials with superior mechanical properties.

This dissertation begins by examining the "brick-and-mortar" structure of nacre, which informs the design of layered polymer-graphene nanocomposite films. Using coarse-grained molecular dynamics simulations, I elucidate mechanisms of dynamic wave propagation and energy dissipation in these systems, providing critical …

Descent Into The Wild: Nature, Nudity, And The Night, Mary E. Adams

LSU New Orleans Theses and Dissertations

My work explores the intersection of vulnerability, autonomy, and the female form by placing nude self-portraits within expressive, psychological landscapes. Drawing from historical representations of women in art, I subvert traditional narratives that have romanticized and objectified the female body, instead presenting figures that exist on their own terms. The night, with its inherent intimacy and uncertainty, deepens this exploration, amplifying themes of exposure, solitude, and self-reclamation.

Through large-scale oil paintings, I engage with ecofeminist ideas, paralleling the exploitation of women and nature while resisting their passive idealization. These figures are not objects of consumption but active presences navigating the …

Foodways As Agentive Response To Disaster In Colonial New Orleans: The French Quarter Fires Of 1788 And 1794, Helen V. Bouzon

LSU New Orleans Theses and Dissertations

Disasters have plagued the City of New Orleans since its foundation in 1718. This year marks the twentieth anniversary of Hurricane Katrina. Most locals have personal memories of Hurricane Katrina or have friends and family who experienced the storm. The effects of Hurricane Katrina were far-reaching and often life-changing. However, Hurricane Katrina is not the only major disaster to have left an indelible mark on the landscape and culture of New Orleans. Two fires in the eighteenth century destroyed significant portions of the colony and left approximately seventy percent of the population homeless. And yet, we know very little about …

Nonparametric Methods For Bayesian Community Detection In Complex Networks, Kedran Young

Graduate Theses and Dissertations

Network analysis is becoming an increasingly popular interdisciplinary area of study, with emerging interest in fields like sociology, biology, economics, and ecology. Within the niche of network analysis, capturing the community structure of a network is one important achievement that many statisticians have been working toward over recent decades. The most popular modeling technique for latent community detection is the Stochastic Block Model (SBM), which falls into the category of latent variable models and will serve as the baseline model throughout this thesis. SBM is widely regarded as the most effective community detection method as it detects latent community membership …

Literary Postcritique And American Transcendentalism: Helping Students Practice Community-Building By Rewilding Literature In The Classroom, Tate Aldrich

Graduate Theses and Dissertations

Literary postcritique is an emergent theoretical approach to literature that has elicited skepticism among many in academia because of its central claim that their unchecked overreliance on suspicious and symptomatic reading styles is diminishing the pedagogical potential of our reading together. To restore this potential, Rita Felski, a champion of literary postcritique, suggests adopting an aesthetic reading style, a mid-level interpretation that neither indulges in the formalists’ habits of close scrutiny nor in the cultural critics’ wider lens of political and social contexts. In The Limits of Critique and Hooked, Felski argues that an aesthetic reading style can develop …

Investigating Evolution Through The Lens Of Ai-Driven Protein Exploration And Phylogenetic Modeling, Mataya Duncan

Graduate Theses and Dissertations

Recent advances in computational biology, artificial intelligence, and sequencing technologies have enabled new perspectives for addressing longstanding questions in evolutionary biology. Increased computational power has made large-scale simulations feasible for investigating diverse aspects of evolutionary and phylogenetic modeling. Similarly, deep learning algorithms now allow for the prediction of reasonably accurate tertiary protein structures, unlocking the potential for investigating diversity and evolution of protein structure across a broad range of organisms. This thesis presents two studies that target different aspects of evolutionary inference from unique perspectives. Yet, the share an overarching goal of presenting new perspectives on the evolutionary basis of …

Application Of Ordinal Regression Models To Acquired Stress Resistance In Wild Strains Of Saccharomyces Cerevisiae, Carson Stacy

Graduate Theses and Dissertations

This thesis explores the application of ordinal regression to the analysis of semi-quantitative growth assays often used when comparing fitness for different strains of the model yeast Saccharomyces cerevisiae. For stress survival assays, yeast stress resistance is measured using an ordered survival score that ranges from 0 (no growth) to 4 (confluent growth). Traditional approaches to analyze this type of data either treats data as a nominal categorical variable or as a continuous numerical variable. These approaches risk loss of information or violation of testing assumptions. In contrast, cumulative logit ordinal regression uses the information contained in the order …

‘King Of Infinite Space:’ Confinement And Identity In Hamlet & Contemporary Adaptations, Anna-Laura Houston

Honors Theses

This thesis explores the theme of identity confinement through the lens of Shakespeare's Hamlet and its contemporary adaptations, Fat Ham by James Ijames and Rosencrantz & Guildenstern Are Dead by Tom Stoppard. At the core of this comparative study is Hamlet's paradoxical claim that he could be "a king of infinite space" were it not for his "bad dreams," a statement that encapsulates the tension between internal autonomy and external constraint. The thesis argues that Hamlet's sense of self is shaped-and ultimately fractured-by external demands, including his father's ghostly command for vengeance, the political corruption of Denmark, and an existential …

The Evils Of Illegitimacy: The Construction And Contest Of Kinship-Based Citizenship During Jamaica’S Nationalist Awakening (1930-1945), Ryan Doherty

Honors Theses

Illegitimacy, which refers to kinship units and births outside of the nuclear family, was a major issue in Jamaica. Following the 1938 Uprising, illegitimacy became even larger as an issue as the colonial administration blamed the lower class’s revolt on their kinship units. As for nationalists, the 1938 Uprising was a catalyst for them to rally the lower class to their side, but they, too, were concerned about their illegitimate kinship units. The colonial administration used illegitimacy as a way to push back against nationalists, while nationalists blamed illegitimacy on the colonial administration’s economic exploitation and mismanagement, as well as …

Substrate Complexity Is Not Correlated With Skin Pattern Complexity In Callistoctopus Furvus, Emily Lekas

Honors Theses

Callistoctopus furvus is an understudied, nocturnal octopus that inhabits shallow, subtropical waters in the western Atlantic. This species relies on camouflage to blend in to diverse environments to escape predators. To understand the relationship between substrate and skin patterning in this species, we used second-by-second analysis of video data recorded in the field. We compared frequencies of four substrate types (sand, rock, algae, and seagrass) ranked by contrast across ten skin patterns displayed by C. furvus. Chi-squared analyses showed significant results that the four substrates were unevenly represented in every skin pattern. However, the data did not support our hypothesis …

Hi Barbie! A Cultural Phenomenon Illustrates How Courts Have Lost The True Meaning Of The Independent Creation Defense, Shelby Harrison

Northern Illinois University Law Review

From movies to advertisements to department stores, Barbie is everywhere. Barbie has been around for decades and is now a cultural phenomenon. It is almost impossible to not be familiar with the iconic fashion doll. With a creation so popular and so powerful, how do other individuals or businesses create their own doll without being influenced by Barbie? This Note discusses the independent creation defense within copyright infringement. The focus of this Note is whether a defendant would even be able to assert the independent creation defense when their opponent’s creation is so widely known, like Barbie. This Note emphasizes …

Dewatering Of Chlorella Algae Using Co2 Gas Hydrate Formation For The Biofuel Production, Sumeet Oak

Master's Theses

When microalgae are processed for producing biofuel, dewatering the algae is an important step, particularly when combined with extracting valuable byproducts like algal oil. Conventional methods like centrifugation and filtration can be harsh on the algae and usually need high-energy inputs. In this work, the new application of CO2 gas hydrates as an algae dewatering agent was investigated. A CO₂ hydrate, CO2-nH2O, where n (n>5.75), is a nonstoichiometric compound where water molecules with hydrogen bonds are structured in an ice-like fashion to form polyhedral cavities. CO₂ gas hydrates are crystalline because gas molecules are trapped in a lattice of …

Edouard Reményi And Johannes Brahms: A Lifelong Influence Reconsidered, Katherine Marie Martin

Master's Theses

Edouard Reményi was one of the first important influences in Johannes Brahms’s life and compositional career. Yet, beyond a single biography, much of what is commonly believed about Reményi is based on information provided by the Brahms literature.

By reexamining the accounts of Reményi in the Brahms literature, and comparing them with Mary Kelley and George Upton’s biography of Reményi and Robert Eshbach’s excellent research, the timeline of Reményi’s life and work can be clarified. Analysis of a set of three pieces for violin and piano demonstrates Reményi’s work as a composer and illustrates the style of Hungarian music that …

A Bishnoi Woman’S Odhani: Gendered Labor, Environmental Ethics, And Textile Traditions In Rajasthan, Nidhi Patel

Department of Anthropology

This report examines an embroidered odhani (woman’s shawl) attributed to a Bishnoi artisan from Rajasthan, India. The odhani is housed in the May Weber Ethnographic Study Collection at Loyola University Chicago. Close analysis of technique and contextual evidence is used to reattribute the textile, which was originally mislabeled and situates it within the contexts of gendered labor and environmental ethics within the Bishnoi community. Utilizing the frameworks of materialist and eco-spiritual feminism, the report argues that the odhani functions as a site of ecological resistance, cultural transmission, and women’s embodied knowledge, as well as a garment.

The Everglades, Caloosahatchee, And Lake Okeechobee: Challenges And Opportunities, Benjamin Simmons

Student Work

“There are no other Everglades in the world” and nothing anywhere else is like them (Douglas, 1947, p.1). Marjorie Stoneman Douglas, a Medal of Freedom recipient, and author of the famous book The Everglades: River of Grass, helped bring the Everglades to the world’s attention with that opening line. The Everglades are now recognized as a cultural icon, a World Heritage Site, an International Biosphere Reserve, and perhaps the most famous wetland on Earth. The Everglades have also been reviled by both politicians and the populace as a Godforsaken swamp and suitable only for the home of noxious vermin. But …

Dialectal Variations Of Food Terms In The Spanish-Speaking World And Their Causes, Dylan Muccino

Honors Theses

This study explores the dialectal variations of food-related terms across the Spanish-speaking world, emphasizing their multilingual etymological origins. Using etymological dictionaries and sociolinguistic sources, the study categorizes food-related lexical variants into five main root language groups: Arabic/Afro-Asiatic/European, Pre-Columbian Caribbean, Mesoamerican, South American, and unknown or unique origins. The findings represent the persistence of Indigenous influence, the impact of Arabic on Peninsular Spanish, the development of Spanish from Latin, and the role of analogy and adaptation in naming unfamiliar items, illustrating the dynamic and complex relationship between language, culture, and history.

The Effect Of Catalyst Choice On Biodiesel Yield And Quality Using Waste Cooking Oil As A Feedstock, Neka Long

Honors Theses

Biodiesel is one current area of interest as a replacement for traditional diesel fuel. Benefits of biodiesel include that it can be derived from renewable resources, and it possesses properties similar to that of traditional diesel fuel. Biodiesel is often produced through a catalyzed transesterification process, which involves the use of a catalyst to aid in the conversion of triglycerides into alkyl esters. A method called the transesterification double step process (TDSP) was researched and used in this project due to the success seen using this method for the conversion of waste cooking oil to biodiesel. In this project, four …

Christianity And Environmental Stewardship: Locating A New Christian Environmental Ethic In Response To The Climate Crisis, Claire E. Sims

Honors Theses

In Lynn White Jr.’s essay, “The Historical Roots of Our Ecological Crisis,” White argues that Christianity has heavily influenced society’s view of the environment. Rhetoric from Genesis has led people to believe that God intends, and even commands, that humans have dominion over the earth. This narrative provides justification for the abuse of the environment at large, abuse that has been compacted over time to create the climate crisis that we are currently experiencing. Though White’s argument lacks some nuance and somewhat exaggerates Christianity’s role in the environmental crisis, I believe his thesis to be true: Christianity does have a …

Naturam Expellas Furca, Tamen Usque Recurret: Theorizing Approaches To Nature In Antiquity, Ca. 800 Bce 450 Ce, William K. Edwards

Honors Theses

Ancient thinkers reflected on nature and engaged with their abstractions in accordance with many different conceptual frameworks. These frameworks were numerous and diverse, characterized by varying interpretations of nature. Hebrews, Greeks, Romans, and early Christians each adopted approaches to nature; these approaches, conceptual and abstract, were in some ways similar, but also distinct. By analyzing the relevant primary sources, this thesis will investigate the similarities, differences, and interplay between these ancient theoretical frameworks. This thesis will investigate philosophical, theological, historical, ecological, and cultural perspectives on nature. An analysis of these ideas, being aware of their historical contexts, will allow us …

Boxed In: Prose Poetry And Transgender Poetics, Lee Hooker

Honors Theses

Though lived experience is essential to every poet's work, transgender poetry especially must be filtered through the poet's "diet." The manifestation of this experience often results in cross-genre works, such as the prose poem. This thesis consists of a craft essay, in which contemporary queer poets and their genre-bending works are examined, and a creative portion, which emphasizes transgender experience and the prose poem.

Evaluation Of Avenanthramide-A As A Skin Penetration Enhancer: In Vitro And In Vivo Testing On Permeation Of Magnesium Ascorbyl Phosphate And Diclofenac Sodium From Topical Gels, Darshil Dhiren Shah

Selected Full-Text Dissertations 2020-

Topical and transdermal drug delivery are favored to deliver active pharmaceutical ingredients directly to the skin as an alternative to oral administration for systemic effects. In either case, the active molecules must cross the stratum corneum and epidermis to reach the site of action. The stratum corneum serves as a primary barrier limiting compounds from fully penetrating the skin. Therefore, it is necessary to add penetration enhancers to topical formulations to enhance drug delivery through the skin. Often, penetration enhancers are also irritant to the skin. Earlier research in our pharmaceutical laboratory showed that an addition of colloidal oatmeal, produced …
