Optimizing Option Market Clearing, Juan Andrés Malaver Alvarado

Electronic Theses and Dissertations

Modern options markets clear each strike in isolation, leaving cross-strike arbitrage unexploited. This thesis applies a payoff-dominant clearing mechanism to realized trades—roughly 2 000 Cboe VIX option executions from June–November 2016—after classifying each trade’s side and bundling by expiration. Three optimization formulations are tested: a fractional linear program (LP), a mixed-integer LP, and a pure integer program. On a 10-core laptop every bundle solves in < 0.5 s. The LP captures the greatest surplus, yet the integer models recover nearly as much while filling whole contracts and holding only modest margin. Results reveal persistent, albeit small, inefficiencies in executed trades and demonstrate that an integral cross-strike auction could operate in real time. The accompanying C/Gurobi code is modular and readily extendable to early-exercise options. Trade-level evidence thus supports redesigning exchange clearing to consider the complete option book.

Reading Interventions In The Modern Era: Reconceptualizing The Utility Of Video Games, Senaida Mehmedovic

Electronic Theses and Dissertations

Youth in the United States continue to have difficulty developing reading skills, with only 31% of fourth graders reading at a “proficient level” (NAEP Reading: National Average Scores, 2024). Youth struggling to develop reading skills often have reading anxiety (Chow et al., 2021; Martinez, 2019; Ramirez et al., 2019), which impacts their reading skill development even more (Mohammadpur & Ghafournia, 2015); the interwoven and cyclical relationship between reading anxiety and reading comprehension requires interventions to address these needs concurrently (Francis et al., 2019; Francis et al., 2021; Grills et al., 2012). The increased avoidance and paired aversion of reading-related tasks …

The Self That Practices Deeper Teaching: An Exploration Of Influences On Teacher Beliefs And Values, Kerstin L. Rowe

Electronic Theses and Dissertations

For decades, educators have called for “a fundamental redesign of the industrial-age classroom.” However, despite ongoing discourse around educational reform, the majority of teachers still use the industrial model of education while too few teachers implement deeper teaching practices which situate students as active learners in addressing complex, real-world challenges rather than being passive recipients of knowledge. Existing literature does not explore the influences upon the beliefs and values of teachers who create deeper learning experiences.

This qualitative study employs educational criticism and connoisseurship to illuminate the inner self of those who practice deeper teaching. Drawing on in-depth observations, interviews, …

The Positivity Effect In Contracts, Megan Kathryn Stricker

College of Science and Health Theses and Dissertations

The positivity effect is a noted preference for positive information over negative information in older adults’ cognition. This effect has been observed in multiple domains of cognition, including both attention and memory (Carstensen & Mikels, 2005). Evidence for the positivity effect has shown up consistently in replications across type of memory (Reed et al., 2014), and this phenomenon can be considered within the context of other trends of cognitive aging. Most if not all research in this area has been constrained to laboratory settings, and there has been limited research as to the context sensitivity of this observed effect. What …

Object-Based Image Analysis And Artificial Intelligence Identification Of Anthropogenic Disturbance On Lesser Prairie Chicken Habitat In Cheyenne County, Colorado, Tara Hoelzer

Geography and the Environment: Graduate Student Capstones

Renewable energy projects often require extensive landcover for their operations. When one of these projects encroaches into territory of threatened species, such as Lesser Prairie Chickens, an analysis of habitat suitability and human disturbance is required to proceed. Traditionally, this involved manually reviewing aerial imagery within a 6-mile radius, digitizing features, and interpreting them using a human technician—an approach that was time-consuming and prone to human error. By using pretrained AI models within Model Builder™, the identification of roads and structures was automated, making the process faster and more consistent than manual visual analysis. As AI and technology continue to …

Enhancing Neuronal Viability: The Protective Role Of 10% Human Cerebrospinal Fluid In Primary Neuronal Cultures, Vineet Arora, Alicia Bernhardt, Alessandro Naopli, Mijail Serruya

Farber Institute for Neuroscience Faculty Papers

Human cerebrospinal fluid (hCSF) is a physiologically rich medium containing neurotrophic factors, signaling molecules, and essential metabolites that support neuronal development, survival, and function. While its neuroprotective properties have been demonstrated in organotypic brain slices and human iPSC-derived models, its application in primary rodent cortical neuron cultures-a foundational system for studying synaptic development and neurodegeneration-remains underexplored. In this study, we systematically evaluated the effects of hCSF supplementation on neuronal viability in primary cortical cultures derived from embryonic day 18 (E18) rat embryos. To determine the optimal concentration, we tested a range of media:hCSF ratios and identified 90:10 (i.e., 10% hCSF) …

Multi-Field Quantum Conference Key Agreement Using An Integrated Photonic Green Machine, Benjamin J. Fisher

Theses and Dissertations

Quantum Conference Key Agreement (QCKA) enables a group of users to generate a shared secret key, which reduces the latency and equipment overhead of establishing multiple Quantum Key Distribution (QKD) links. Conventional QCKA protocols send a multi-photon entangled state from one user to others and a key is generated only when all photons are detected, which is inefficient at high loss and opens side-channels at the receiver side. Here, we overcome this barrier through a multi-field QCKA protocol enabled by designing, fabricating, and testing an integrated photonic Green Machine that implements an eight-mode Hadamard unitary transformation through a beam-splitter network. …

Exploring The Effects Of Africana Studies On Black Undergraduate Students: A Qualitative Case Study, Lanaya M. Butler

Electronic Theses and Dissertations

Particularly in the context of American K-12 schools, education has been manipulated to control—rather than liberate—students through the erasure and distortion of Black history, experiences, perspectives, and capabilities. Additionally, American schools prioritize memorization and obedience while failing to equip students with critical thinking skills. As a result, students are trained to become workers rather than innovators, worldbuilders, and change-makers. For nearly a century, Black educational critics have stated that these systems were designed to subjugate Black community members through dehumanization and enslavement of the mind. These critiques are foundational to the aims of Afrocentric education which posits the life experiences …

Computational Fluid Dynamics And Fluid Structure Interaction Modeling In Healthy Vertebral Arteries: A Comparative Study, Bryce Clinkenbeard

Electronic Theses and Dissertations

Cerebral perfusion is critical for maintaining proper brain function, with each cerebrovascular artery playing an integral role in the overall cerebrovascular system. When these arteries become damaged or develop plaque, cardiovascular disease (CVDs) such as atherosclerosis can arise, leading to conditions like arterial stenosis. While CVDs are most prevalent in older individuals, they are also observed in young adults, particularly those engaged in high-endurance occupations such as military service. Diagnosis and prediction of CVDs often rely on imaging modalities supported by computational fluid dynamics (CFD) which account for low resolution in fluid flow. CFD models assume rigid arterial walls, which …

Development Of An Embedded Iot Board For Real-Time Floor Estimation Of Autonomous Robots, Carter J. Sorensen

Electronic Theses and Dissertations

As service robots become more prevalent in multi-story environments such as hospitals, hotels, and laboratories, accurate floor-level detection is critical to ensuring operational reliability. Consider a robot tasked with delivering medical samples in a multi-story laboratory. Without accurate feedback, a robot exiting on the wrong floor could introduce delays, disrupt workflows, or compromise sample integrity. Internet of Things (IoT) technologies offer a way to address these risks by providing real-time error detection and corrective capability. However, current IoT-based floor estimation systems often require invasive modifications to building infrastructure—particularly elevator control panels. These approaches introduce challenges related to cost, liability, backward …

Countering The Demand Side Of Foreign Bribery: An Analysis Of The Foreign Extortion Prevention Act, Noah Buyon

Duke Journal of Comparative & International Law

The United States has long criminalized bribery of foreign officials but not bribery by foreign officials. Under the Foreign Corrupt Practices Act ("FCPA"), an American may be criminally liable for paying a bribe to another country's official, but the official commits no corresponding crime. The official might face criminal charges if they launder the proceeds of the bribe through the United States and could find themselves the target of Executive Branch sanctions for their corrupt behavior. But until 2023, the United States largely left the official's punishment, if any, to the official's home country. Then, Congress passed the Foreign Extortion …

Degraded Document Binarisation, Miriyala Ajith

Master’s Dissertations

In this study, I explored degraded document binarization by reviewing two recent model frameworks and implementing their models using PyTorch. The first model is based on cGANs, specifically the DE-GAN [41] framework, which enhances degraded documents by restoring their quality prior to binarization. The second model employs vision transformers [40], inspired by the DocBinFormer architecture, which uses an autoencoder in both the encoder and decoder for effective binarization. Both models were evaluated on the ISI-Bengali dataset. Experimental results demonstrate that DE-GAN improved document quality by 4% compared to the degraded input, while the vision transformer model achieved a 14% improvement, …

“Eyes Can Be Blinded”: A Narratological Analysis Of Focalization In Sarah J. Maas’S A Court Of Thorns And Roses And A Court Of Silver Flames, Georga Mae Feek

Electronic Theses and Dissertations

This thesis explores the complex relationship between Feyre and Nesta, two prominent characters in Sarah J. Maas’s A Court of Thorns and Roses (ACOTAR) and A Court of Silver Flames (ACOSF). My analysis uses narratological concepts from three significant scholars in narrative theory: Gérard Genette, Shlomith Rimmon-Kenan, and Mieke Bal. I begin with a theoretical synthesis of narration and focalization and outline the various categories of types of narrators and focalizers. Then, I analyze Feyre’s focalization in ACOTAR and Nesta’s focalization in ACOSF. Through this process, I have developed rich character studies of Feyre and Nesta. My investigation of the …

Drawing upon social learning theory, intersectionality, and relational-cultural theory, the study employs a multidisciplinary framework to analyze how CSE functions as both an instructional practice and a sociocultural intervention. Utilizing an integrative thematic review of empirical studies, policy analyses, and national curriculum standards, the research evaluates the extent to which CSE promotes emotional literacy, fosters ethical relationship skills, and addresses structural inequities in educational access. Findings indicate that well-implemented, inclusive CSE contributes to healthier developmental outcomes by enhancing students' emotional …

Some Results In Thermodynamic Formalism, C. Evans Hedges

Electronic Theses and Dissertations

This dissertation investigates several key questions at the intersection of dynamical systems, computability theory, and thermodynamic formalism. In the symbolic setting, we establish novel results regarding the statistical properties of equilibrium states, deriving bounds on probabilities of configurations and relating these bounds to the Gibbs property through the homoclinic relation. Additionally, we examine the computability of thermodynamic quantities such as pressure, ground state energy, and residual entropy. We show that topological pressure is computable from above for general subshifts and computable for strongly irreducible shifts, with similar results extending to ground state energy and residual entropy.

Extending beyond subshifts, we …

The Embodiment And Experiences Of Gender Euphoria Among Transgender And Nonbinary Communities: A Mixed Methods Inquiry, Brendon T. Holloway

Electronic Theses and Dissertations

Gender euphoria is a critical aspect of embodiment for transgender and nonbinary (TNB) people that has long been overshadowed in academic research by deficit narratives and gender dysphoria. While gender dysphoria is the distress an individual may experience related to their gender, gender euphoria encapsulates the positive emotions a TNB person may experience because of positive gendered experiences. Despite community documentations of gender euphoria since the 1970s, academic research on gender euphoria has only recently begun to emerge. This three-paper dissertation advances this body of scholarship by exploring how gender euphoria is conceptualized, experienced, and embodied in TNB communities. Utilizing …

This research calls for reform grounded in transparency, comparability, and justice for …

The Narratological Maus, Isla Lader

Electronic Theses and Dissertations

The Complete Maus, a memoir graphic novel surrounding the events of character Art Spiegelman as he collects, records, and illustrates his father’s life pre-the Holocaust in Europe, his time in Auschwitz, and then life in the United States has been one of the focal Holocaust survivor testimonies and has redefined the genre it exists in as both a graphic novel, but also as a form of testimony. Like many popularized works dealing with the Holocaust, though, cultural preconceptions of Jewish people, genocide, and audiences’ desire to find morals within the work have made it so often audiences come to …

Sustaining Queerness: A Phenomenological Study Of Colorado Educators, Devani Lemmon

Electronic Theses and Dissertations

The purpose of this study was to engage queer Colorado educators to explore how to sustain their identities as queer educators in a politically fractured state. By focusing on Colorado, I could assess the extent to which the legal protections afforded there adequately support educators in sustaining themselves. Additionally, the findings from Colorado had the potential to further illuminate factors influencing teacher sustainability and retention on a much larger scale. The questions for this research project were: 1) How are queer educators sustaining themselves and each other in an increasingly volatile political climate? 2) What, if any, factors impact queer …

Carbon Monoxide Releasing Polymeric Micelles, Riya Joshi

Electronic Theses and Dissertations

Carbon monoxide (CO), traditionally known as a toxic gas, has emerged as a potential therapeutic agent due to its cytoprotective, anti-inflammatory, and vasodilatory properties. This study explores the development of CO-releasing polymeric micelles as a controlled delivery system for biomedical applications. Using ring-opening metathesis polymerization (ROMP), we synthesized diblock copolymers incorporating CO-releasing moiety diphenylcyclopropenone (DPCP) with hydrophilic polyethylene glycol (PEG) to enhance solubility and stability of the overall CO releasing system. Dynamic light scattering (DLS) and electron microscopy (EM) confirmed the formation of well-defined micelles, while fluorescence assays demonstrated efficient CO release with the use of Iridium photocatalyst under 470 …
