Time Is A Tree: Arboreal Chronotopes & Reciprocal Dendrochronology, Alyssa Bernard

Theses & ETDs

This thesis proposes a framework for reciprocal dendrochronology, a decolonial approach to tree-ring science that shifts the role of the researcher from an extractive observer to a vessel for translating arboreal memory, and explores how trees function as chronotopes: material intersections where time and space are fused into a living record (Bakhtin 1981). By applying the structuralist frameworks of Claude Lévi-Strauss (1955) and Joseph Campbell (1949), it is argued that trees have long functioned as universal symbols of continuity and the axis of existence. This baseline is then brought into conversation with the chronotopic theory of Mikhail Bakhtin (1981) and …

Reproductive Characteristics Of The Chain Pipefish, Syngnathus Louisianae, David Kelley

Theses & ETDs

Syngnathids: pipefish, seahorses, and seadragons in the family Syngnathidae, are an evolutionarily unique, yet often understudied group of species typically found in shallow seagrass habitats, defined by their collection of extremely specialized adaptations, which include but are not limited to: male pregnancy, elongated and rigid bodies with bony plates, small fins not well suited for swimming, and fused jaws that form long and thin snouts. This study examines the species Syngnathus louisianae, a large pipefish native to coastal waters, namely seagrass and sargassum habitats, in the Gulf of Mexico and Atlantic Coast. This species was chosen for this study over …

Back To The Bayfront, Dania Hefley

Theses & ETDs

I’m trying to make sense of the different versions of myself that existed inside New College over the last four years. How I existed while studying. Which classrooms made me feel like a person. Which professors taught me how to read. Which ones taught me how to think. Which ones made me want to rise to the level of the room. Which ones made me feel like I was disappearing. I don’t want to turn these four years into a lesson, but I need a way in that lets me see the throughline. Recently, my literature professor, Miller, was talking …

Understanding Tlr3 Immune Response Activation In Cryptosporidium Parvum And Cryspovirus Pathogenesis, Surayya Hudayberganova

Biochemistry and Molecular Biology

Cryptosporidiosis is a serious gastrointestinal illness caused by a protozoan parasite known as Cryptosporidium. It is particularly dangerous for malnourished children and those with compromised immune systems. My research focuses on the Toll-like receptor 3 (TLR3) response to the Cryptosporidium parvum infection, specifically in the presence of the parasite’s viral mutualist named cryspovirus (CSpV1). Results using research methodologies like ELISA and RT-qPCR have indicated that TLR3 expression increases during the infection process of Cryptosporidium parvum (C. parvum). Furthermore, one intriguing observation concluded during this study suggests that administering the TLR3-specific inhibitor CU-CPT4a to infected cells drastically decreased this activation. This …

Synthesis And Characterization Of Bis(Pyrazolate) Metal-Organic Frameworks For Carbon Dioxide Adsorption And Sequestration, Emily Granville

Theses & ETDs

There has been an increase in carbon dioxide (CO2) emissions into the atmosphere due to the burning of fossil fuels for energy, vehicle transportation, industrial factories, and deforestation. This is harmful to the environment as it is the primary factor of climate change and ocean acidification. To help solve this issue, scientists have been using metal-organic frameworks (MOFs) to adsorb and sequester the CO2 due to the highly porous crystalline structures and open metal sites of the MOFs. Hard metal cations act as hard Lewis acids that would coordinate in the open metal site, which attracts the lone pair on …

Effects Of Early Life Karenia Brevis Exposure On Bottlenose Dolphin Calves In Sarasota Bay, Florida, Elizabeth Fry

Theses & ETDs

Harmful Algal Blooms (HABs) have increased in frequency, intensity and geographic distribution in the past several decades. Florida is an epicenter for an HAB, commonly referred to as red tide, caused by the algal dinoflagellate Karenia brevis, which produces the neurotoxin brevetoxin. Acute exposure to brevetoxin causes respiratory distress and has been associated with large scale marine mammal mortalities and fish kills. However, potential chronic effects of exposure, including via maternal transfer, have not been well characterized. Fetal and juvenile mammals may be particularly susceptible to the neurobiological effects of excitotoxins due to their developmental stage. Many resident coastal bottlenose …

Rhetorical Models Of Conspiracy Theories How Two Political Commentary Youtubers Build Narrative Authority, Riley Bucklin

Theses & ETDs

The purpose of this study is to explore the rhetoric that independent political commentators on YouTube used to develop conspiracy theories in the immediate aftermath of Charlie Kirk’s murder. On September 10th, 2025, Charlie Kirk — a prominent conservative political commentator and activist — was assassinated at a Turning Point USA event on Utah Valley University campus. Following the shooting, various conspiracy theories developed online as the narrative from the federal investigation was still developing. This study is necessitated by the rapid pace at which digital subcultures have displaced traditional media outlets and reshaped what is considered trustworthy reporting. To …

Inbreeding Effects On Fitness-Related Traits: Evidence From Two Populations Of The Least Killifish (Heterandria Formosa), Abigail Hansen

Theses & ETDs

Inbreeding, the mating of closely related individuals, can affect the fitness and overall health of natural populations by reducing genetic diversity and exposing deleterious recessive alleles. To better understand the effects of inbreeding, a controlled lab experiment was conducted using the Least Killifish species, Heterandria Formosa. Many species have evolved behavioral and demographic mechanisms to avoid inbreeding; however, these mechanisms can be constrained in small or structured populations. This species was purposely chosen for this experiment as the fish appear in two diverse populations; a population with high density from the Wacissa River (WR) located in South-Central Jefferson county, Florida …

Sunless, Gabriel Olah

Theses & ETDs

My thesis is simple. It is a novella which I have been working on in one form or another for the better part of a year and a half. Over my lengthy times working on this work, it has changed shape drastically, just as any proper story should. Characters were added and dropped, locations were visited and left behind, ideas and plotlines developed or removed, all eventually being boiled down into this current version. This is a version I hold no belief in being perfect, for perfect is the enemy of done, but I am of the belief that it …

Revised - The Role Of Gad67/65 In The Therapeutic Effects Of Ketamine And Fluoxetine In Fear-Conditioned Mice, Alex G. Ottimer

All NMU Master's Theses

Post-traumatic stress disorder (PTSD) is a chronic psychiatric disorder and the most common disorder following exposure to a traumatic event. The most commonly used drugs in PTSD treatment are selective serotonin reuptake inhibitors (SSRIs), though only about 50% of patients respond to this treatment. Previous work in our lab demonstrated the combination of chronic fluoxetine (FLX) and acute ketamine treatment decreased fear response in a contextual fear paradigm in male C57/BL mice. In rodents, fear conditioning (FC) is commonly used in the literature to induce behaviors related to PTSD. The mammalian central fear memory circuit involves a dynamic interplay between …

Beyond The Cycle: How Menstruation Influences Gender Identity And Well-Being In Binary And Non-Binary Adults, Rin Nguyen

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Approximately 1.8 billion people worldwide menstruate, including transgender and gender-diverse (TGD) people, yet their experiences remain underrepresented in research. Given that menstruation can affect gender alignment and psychological well-being, understanding its impact on TGD people is critical. Gender congruence, or alignment between one’s gender identity and expression, is a key factor influencing well-being, with research linking it to reduced depression and anxiety. Furthermore, emerging research on gender euphoria, the joy experienced when gender congruence is experienced, suggests it may serve as a protective factor for mental health and well-being. Gender euphoria has been associated with reduced psychological distress and increased …

Materials and methods: Twenty extracted human teeth were sectioned longitudinally to obtain standardized specimens. Samples were assigned to ultrasonic preparation using …

Recruitment Of Chrysaora Chesapeakei On Floating Docks Versus Bulkhead Surfaces: Which Axis Is Foulset?, Alyssa Lamberto

Theses, Dissertations and Culminating Projects

Blooms of Chrysaora chesapeakei (bay nettles) have increased sharply in Barnegat Bay, New Jersey, reducing both ecological integrity and economic value. Because population expansion is driven primarily by the benthic polyp stage, where individuals attach to hard substrates and reproduce asexually, effective management must target the surfaces where polyps settle and clone themselves. The rapid growth of artificial infrastructure, particularly vinyl docks and bulkheads, has expanded available habitat for polyp recruitment. Scrubbing these structures has been shown to reduce ephyrae production, but it remains unclear whether both docks and bulkheads warrant equal management attention. This study compared recruitment on horizontal …

Individual Recognition: Do Horned Passalus, Odontotaenius Disjunctus, Display Individual Discrimination Of Familiar And Unfamiliar Conspecifics Through Changes In Their Behavior?, Sabrina Galloza

Theses, Dissertations and Culminating Projects

The horned passalus, Odontotaenius disjunctus, are subsocial beetles that inhabit and defend decaying wood where they create galleries to live, mate, breed and provide brood care. The species is well known for their stridulations, making up to 14 different sounds, having one of the greatest repertoire of sounds for any known arthropod. Typically living in family units, it has been found that several families can inhabit the same log, therefore, the horned passalus can come into contact with both kin and non-kin. It is currently unknown whether the horned passalus can distinguish between nestmates and non-nestmates. Additionally, it is unknown …

Introduction: Inflammatory bowel disease involves aberrant immune responses and is associated with both cardiovascular disease risk and altered intestinal blood flow. However, little is known about how inflammatory bowel disease affects regulation of perivascular nerves that mediate blood flow. Previous work found perivascular nerve function is impaired in mesenteric arteries with Inflammatory bowel disease. The purpose of this study was to determine the mechanism of impaired perivascular nerve function.

Methods: RNA sequencing was performed on mesenteric arteries from IL10−/− mice treated with H. hepaticus to induce disease (inflammatory bowel disease) or left non-gavaged (Control). For all other studies, Control and …

Experimental Data-Driven System Identification Of Scale-Model Airboat Dynamics For Control And Autonomy Applications, Miguel A. Trejos

LSU New Orleans Theses and Dissertations

To achieve autonomous control of a surface watercraft requires an accurate model describing the dynamics of the system. To this end, the modeling of dynamics of an airboat with a combustion engine-based propulsion system is investigated. Specifically, a black-box data-based approach using neural networks. To facilitate this, a custom data collection system was developed to record linear and rotational motion during field tests. Due to the airboats unique ability to traverse different terrains, not just water, the modeling of dynamics on different terrains was investigated.

Advancement In Electrochemical Generation-Collection: Snapshot Redox Cycling Voltammetry For Rapid Analysis At Chip-Based, Individually Addressable Microband Electrode Arrays, Blake Aleck Sterling

Graduate Theses and Dissertations

Snapshot redox cycling voltammetry (Snapshot RCV) is introduced as a rapid electrochemical technique that reconstructs the current-potential profile of a redox active species using a microband electrode array. By simultaneously biasing individual generator electrodes alternating in the array to different voltages across the analyte’s potential range while individually holding collector electrodes at a reversing potential, “spatial” voltammetry is achieved in as little as 1 s with the temporal speed of chronoamperometry, rapidly capturing the steady-state redox cycling (RC) profiles. During RC (a mode of generation-collection), the analyte is oxidized (or reduced) at generator electrodes and converted back at neighboring collector …

The Florida Highwaymen: Race And Entrepreneurial Art In Jim Crow Florida, Brecken Fair

Theses & ETDs

This paper introduces the Florida Highwaymen, a collective of African American landscape painters who emerged in mid-twentieth century Florida. Previously, the Florida Highwaymen have been viewed primarily as commercial artists producing decorative art for profit. By examining their artistic techniques, cultural context, and the socio-economic challenges they faced, this paper argues that the Highwaymen’s work represents a form of entrepreneurship and artistic innovation. Their paintings not only document the unique landscapes of Florida but their achievements reflect issues of mobility, entrepreneurship, and resilience within the African American community during the Jim Crow Era Florida. This paper also recognizes the talent …

The Evaluation Of Immune Dysregulation Detection In Individuals With Psychiatric Conditions, Alyssa Kiel

Theses & ETDs

32 studies were evaluated in determining detection of immune dysregulation, derived from monocyte, T-cell, B-cell, and protein panels, and identifying trends in disorder-specific biomarker data for different psychiatric conditions including, ASD, schizophrenia, MDD, bipolar disorder, GAD, OCD, ADHD, and C-PTSD. The studies selected reporting significant immune abnormalities from biomarker data, with observed findings of immune dysregulation in psychiatric populations frequently coincided with the prevalence of comorbid physical issues, such as metabolic imbalances, cardiovascular conditions, and gastrointestinal issues. These observations highlight the intersection of altered biomarker variation and comorbid disease outcomes present in individuals (including their sex) with psychiatric conditions compared …

Beyond Skrmetti: A Constitutional Case For Gender-Affirming Care, Mateo-Luis A. Planas, Evan Gerstmann

Honors Thesis

In 2025, roughly 2.1 million adults in America identify as transgender, making up around 1% of the country’s total population. Despite this, the transgender identity has become a focus of political debates and made its way onto the U.S. Supreme Court’s docket in U.S. v. Skrmetti. The issue is not whether transgender people exist, but rather, how they ought to exist legally: if and when one can access medical care to pursue a gender transition. While many American doctors agree that these treatments are life-saving, since 2021, a slew of legislation has limited access for adults 18-21 (AMA, 2021). This …

Music & Emotion: Matching Neurobiological Proxies To Affect Components Induced By Music Modality, William Lopez

Theses & ETDs

The United States struggles with high rates of mental health conditions and their misdiagnosis. Both major diagnostic manuals used in mental health rely solely on behavioral and self-reported measures for their diagnostic criteria. Differential diagnosis could be supported by implementing non-invasive neurophysiological and neuroendocrinological measures. Regarding the treatment aspect of healthcare, music therapists can be equipped with additional tools by understanding how individual manipulations of musical components directly influence emotion. Many music studies examine the general effects of music or conduct correlation analyses of songs that share musical components, rather than employing a controlled paradigm in which near-identical pieces are …
