Interactions Between Black, Brown, Blue And Green Carbon From Terrestrial To Marine Ecosystems: A Critical Review, Allison White, Richard Kline, Md. Saydur Rahman

School of Earth, Environmental, & Marine Sciences Faculty Publications

Black and brown carbon are byproducts of the incomplete combustion of biomass or fossil fuels. These light-absorbing aerosols influence climate by altering the radiative balance through the absorption and scattering of sunlight, exacerbating global climate change. Their subsequent deposition on terrestrial and marine environments affects surface albedo, snow and ice melt, and biogeochemical processes, leading to further environmental consequences. In contrast, green and blue carbon refer to carbon stored in terrestrial vegetation and marine ecosystems, respectively. These ecosystems play a crucial role in mitigating climate change by sequestering atmospheric carbon; however, they are increasingly threatened by climatic disturbances, anthropogenic activities, …

Understanding Mental Health Crisis Response Through The Lens Of First Responders, Ella Gibson

Student Theses

Responses to mental health crises are becoming an increasingly contentious topic as cases of extreme police violence or fatality during a crisis are publicized in the media. Although first responders’ experiences with mental health crisis response have been explored in prior literature, there remains a lack of research that gathers data from multiple first responder roles and compares their experiences across groups. There is also a significant gap in research examining the perspectives of co-response teams. This study sought to gather qualitative data on the experiences of police officers, EMTs/paramedics, and co-response team members, and to explore their perceptions of …

Existence, Difference, And The Nigerian Woman: A Feminist Praxis Beyond Patriarchy, Hannah Yemisi Ajewole

Dissertations

This dissertation investigates the postcolonial condition of Nigerian woman through a critical philosophical engagement with feminist theory, focusing particularly on Simone de Beauvoir’s existentialism and Irigaray’s ethics of sexual difference. It interrogates the historical processes through which gender became the basis of hierarchy in the Nigerian society, arguing that colonial and patriarchal override precolonial forms of relationality—marked by dual-sex relationship and age-based hierarchies—into rigid, male-dominated structures of authority and representation. Drawing also on Oyèrónkẹ́ Oyěwùmí’s critique of western gender epistemologies, the work contextualizes the Nigerian woman’s experience within a broader matrix of colonial imposition, cultural displacement, and epistemic violence. This …

Assessing The Impact Of Social Network On Cyber-Argumentation, Bhargav Krishna Thota

Dissertations

Argumentation is one of the basic activities people perform in our society. People often spend a lot of time arguing about social, cultural, economic, financial, political, and other issues. Existing cyber-argumentation platforms facilitate large-scale discussions among participants and play an important role in the analysis of collective opinions and collective decision-making. However, they do not provide social networking capabilities and are not designed to be used in social networking environments. Social networks in argumentation platforms can reveal the patterns, shifts, and true relationships between the users in a discourse that influence the collective decision-making process, outlier opinions and so on. …

Crux: Exploring Imperialism And Resistance Through Role-Playing Games, Devon Gronka

Institute for the Humanities Master's Papers, Projects, and Capstones

This is a game about power. The game is a Role-Playing Game, or RPG. As with nearly all RPGs, the game presents the players with choices about how their characters will interact with each other and with the world around them, and these interactions are woven together to more or less form a plot. However, oftentimes in life there are no good choices available, and there is no win state outside of what we might determine for ourselves.

The game is a social experiment. While playing a game, a player takes in information in a very different manner than when …

Long-Term Sedimentation Rates And Patterns Of Alluvial Ridge Basins (Esteros) Of The Rio Grande Delta (Tx, United States Of America), Kynan Joseph Rutan

Theses and Dissertations

Little is known about the century-scale sedimentation rates and patterns of Alluvial Ridge basins within river deltas, especially in the Rio Grande Delta (RGD). To better constrain this, 22 cores were collected in the Bahia Grande Complex (BGC) and analyzed for grain size, organic content, age dates, and elemental composition.

Results show that grain size and sedimentation rates decrease from an artificial inlet to the basin interior, with elevated sedimentation in the south. Also, human activities, such as the construction of the Brownsville shipping channel in the 1930s, altered sedimentation dynamics in the basin by blocking natural inlets and leading …

Capsinoids, Non-Pungent Trpv1 Agonists, Induce A Mild Hypothermia That Provides Short- And Long-Term Neuroprotection After Ischemic Stroke, Alexander Andersohn, Alexander Andersohn

Dissertations and Theses (Open Access)

Therapeutic hypothermia (TH) has demonstrated neuroprotection in instances of cardiac arrest and neonatal hypoxia/ischemia but faces different challenges in application to stroke due to the activation of cold defense mechanisms in conscious patients. This dissertation examines the efficacy and specificity of capsinoids (a purified mixture of capsiate and dihydrocapsiate) to induce a sustained mild hypothermia in conscious mice that is neuroprotective after stroke. Capsinoids function as TRPV1 agonists. However, unlike capsaicin, capsinoids are vulnerable to esterase-mediated breakdown, thus significantly restricting their action to the site of delivery. We showed that capsinoids delivered intraperitoneally (IP) to mice induced a TRPV1-dependent drop …

Functional Analysis Of Ftsa-Mediated Recruitment Of Ftsk In Escherichia Coli, Abbigale Perkins

Dissertations and Theses (Open Access)

Bacterial cytokinesis requires precise coordination between cytoplasmic and periplasmic components of the divisome to ensure that membrane constriction and chromosome segregation occur in synchrony. The actin-like protein FtsA plays a central role in this process by tethering FtsZ to the membrane and recruiting downstream division proteins. Despite its essential function, the mechanisms by which FtsA coordinates divisome activation and the recruitment of late-acting proteins remain incompletely defined. To address this, the role of FtsA in activating septal synthesis and recruiting the DNA translocase FtsK was examined using mutational analysis in Escherichia coli.

The FtsA^{M96E R153D} variant, which has …

Neural Dynamics Supporting Flexible Cognition, Meredith J. Mccarty

Dissertations and Theses (Open Access)

Flexible cognition enables humans to adapt their behavior to changing circumstances by prioritizing relevant information and filtering out distractions. This process is thought to be supported by the integration of ongoing behavioral goals with incoming sensory information, but how this integration is realized in the human brain remains unclear. It is unknown how high-order sensory cortices can balance specialized processing with flexible integration of changing behavioral goals. In the following investigations, we use intracranial EEG (iEEG) recordings in humans to study the neural dynamics of flexible cognition during high-order sensory processing. First, we validated assumptions about the locality of iEEG …

Orthogonal Comparison Of Nuclear And Mitochondrial Clonal Architectures In Hematologic Malignancies, Nehali Shah

Dissertations and Theses (Open Access)

Acute myeloid leukemia (AML) is a hematologic malignancy characterized by accumulation of mutations that disrupt hematopoietic differentiation and promote clonal expansion. Understanding how these mutations arise and evolve is essential for improving diagnosis, prognosis, and treatment stratification. Current methods are limited by either restricted genomic coverage (targeted panels) or low throughput and high cost (in single-cell whole genome sequencing, scWGS). An emerging alternative is the use of mitochondrial DNA (mtDNA) mutations as clonal markers.

This study aims to determine whether mitochondrial-derived clonal architectures correlate with nuclear-derived clonal architectures in AML, thereby evaluating mtDNA as a scalable orthogonal tool for lineage …

Governing Complexity: A Comparative Assessment Of Four Governance Models With Applications To Climate Change Mitigation And Adaptation, J. B. Ruhl, Niko Soininen, Barbara Cosens, Lance Gunderson

Vanderbilt Law School Faculty Publications

Responses to ongoing global climate change include economy-wide mitigation efforts and large-scale societal adaptation that demand novel approaches to governance. An array of innovative governance models has been proposed since the late 1900s and early 2000s as scholars observed inadequacies of government-centric and formal legal approaches to natural resource management, complexity and uncertainty, failures of neoliberal economic reforms, and cross-scale institutional arrangements. Four such models have come to dominate the solution-oriented discourse on climate change governance: adaptive governance, transition governance, transformation governance, and anticipatory governance. We compare these models in terms of their origin and applicability to deal with the …

On Sobolev Spaces And The Existence Of Weak Solutions To Boundary Value Problems, Skye X. Paul

Master's Theses

Many boundary value problems that arise in mathematical models have close connections to second order elliptic partial differential equations. This thesis introduces the idea of weak derivatives and Sobolev Spaces to generalize possible solutions. Using functional analysis centered around the Lax-Milgram theorem, we show the existence of these generalized solutions to boundary value problems including Laplace's Equation, 2nd order linear ODEs, and ultimately a general second order elliptic PDE. The work cumulates with recovering a number of central theorems of functional analysis in the context of Sobolev Spaces, creating a new perspective on the solvability of these boundary value problems.

Do You Feel The Power? Affinity Spaces For Black Male Principals, Wallace Cobbs

All Dissertations

This qualitative study explores the experiences of Black male principals by examining how affinity spaces provide essential support in facing the challenges of school leadership. Using semi-structured interviews and a focus group, the research investigates how these spaces influence principals’ self-efficacy as they manage racial microaggressions, systemic barriers, and professional isolation. The findings show that affinity spaces help build confidence, encourage professional growth, and support personal well-being. By connecting self-efficacy theory to the real-life experiences of Black male principals, this study adds to the conversation on equity in education and the need for meaningful, culturally-relevant support systems.

Metabolic Dysfunction Caused By Dietary Oxylipins And The Environmental Toxicant Pfos, Jazmine Alexis Eccles-Miller

All Dissertations

Disruption of fat metabolism is a hallmark of metabolic disease. A liver enzyme, Cytochrome P450 2B6 (CYP2B6) is an anti-obesity enzyme that produced several omega-3 and omega-6 fatty acid metabolites that could contribute to metabolic diseases such as fatty liver disease. Two of these metabolites, 9-HODE and 9-HOTrE, may be associated with fatty liver. Mice were exposed to 9-HODE and 9-HOTrE to investigate whether they contribute to fatty liver disease under fasting conditions. A transgenic mice model expressing the human enzyme CYP2B6 was also fasted to determine if CYP2B6 leads to increased fatty liver under fasting conditions compared to a …

Exploring Halogen Bonding Interactions In Cocrystals And Deep Eutectic Solvents, Madhushi Bandara

All Dissertations

Halogen bonding is a noncovalent intermolecular interaction analogous to hydrogen bonding that occurs between an electrophile and a nucleophile. This is often observed in compounds containing heavy halogens such as iodine and bromine. When these halogens are covalently bonded to another atom or molecule, preferably to an electron-withdrawing moiety, an electrophilic region called a sigma hole is created on the halogen atom on the extension of the covalent bond.

The first study of this dissertation presents a comprehensive characterization of eight newly synthesized triiodide salts using single-crystal X-ray diffraction, powder X-ray diffraction, thermal analysis (DSC and TGA), and Raman spectroscopy. …

Synthesis And Characterization Of Chemically Recyclable Polypropylene-Based Covalent Adaptable Networks, Andrii Tiiara

All Dissertations

Polyolefins (POs) are inexpensive engineering materials with excellent physical and mechanical properties, accounting for nearly 60% of all thermoplastics. However, large-scale recycling remains limited, with only ~15% undergoing mechanical recovery. This dissertation addresses this challenge by fragmenting and functionalizing polypropylene (PP) chains to generate macromonomers and employing them, along with industrial reactive PP macromonomers, to synthesize, depolymerize, and repolymerize chemically recyclable polypropylene-based polyolefins (CR-POs). These CR-POs incorporate ester linkages that form covalent adaptable networks (CANs), maintaining a gel fraction of ~70% while remaining melt-reprocessable via extrusion and compression molding.

First, the fragmentation of PP is investigated by microwave irradiation. Microwave …
