Eritrean Refugees Between Securitization And Survival Along The Sahara Route To Egypt, Zeina Shoukry

Theses and Dissertations

Eritrea remains one of the largest refugee-producing countries in the world, with mandatory military conscription serving as a primary driver of displacement. This thesis examines the precarious journey of Eritrean refugees across the Sahara Desert en route to Egypt, situating this movement within the broader context of border securitization. It argues that the journey itself constitutes a critical and often overlooked phase of the migration process, as significant as both departure and destination.

Drawing on migration infrastructure theory and migrant network theory, this study foregrounds Eritrean refugees’ agency and resilience. It analyzes how refugees mobilize knowledge, digital technologies, social networks, …

Polymer Nanocomposite Dielectrics For High-Temperature Superconducting Cables: Cryogenic Characterization And Testing Environment Development, Jared R. Ericksen

Theses and Dissertations

High-temperature superconducting (HTS) cables require dielectric insulation materials that can withstand cryogenic operating environments while maintaining electrical reliability, mechanical stability, and manufacturing compatibility. This thesis investigates polyamide-based polymer nanocomposites as candidate HTS cable insulation materials and develops cryogenic testing platforms for evaluating thin-film dielectrics at reduced temperatures. Two silicon-based filler systems are studied: sol-gel-derived silicon dioxide (SiO 2 ) nanoparticles and polyhedral oligomeric silsesquioxane (POSS). Dielectric breakdown behavior is evaluated under DC and AC high-potential testing, while mechanical behavior is assessed through tensile testing. The results show that PA/SiO 2 nanocomposites provide the strongest overall balance of mechanical reinforcement and …

Comparing Principal Component Analysis And Sequential Fusion Deeponet With Varying Dataset Size For Design Space Exploration Of Hypersonic Flow, J. Dallan Trentman

A PCA based ROM is developed and compared to a Sequential Fusion DeepONet by comparing model prediction accuracy, training time, and prediction time, across dataset sizes from 25 samples to 1024 samples. These models are applied to 2D hypersonic CFD simulations of the Orion reentry …

Helicopter Pilots’ Safety Behaviors: Identifying Factors That Affect Risk Perception Among Helicopter Pilots, Khaled J. Alzaabi

Theses and Dissertations

Helicopter operations frequently take place in complex, high-risk environments, where pilots continuously assess hazards and make critical decisions under pressure. Despite standardized procedures, regulations, and training designed to enhance safe operations, helicopter pilots may perceive risk differently when encountering similar flight situations. Understanding the factors that influence helicopter pilots’ perception of risk is essential for improving helicopter operation safety.

The purpose of this study was to investigate the effect of various factors on risk perception among helicopter pilots. Using an explanatory correlational design, the study assessed whether helicopter pilots’ demographics, flight experience, and affective domain factors explain differences in their …

Radiation Effects On The Amd Versal Running An Automatic Modulation Classification Model, Allan D. Howe

Theses and Dissertations

With the recent increase of interest into artificial intelligence (AI), graphics processing units (GPUs) have been used as the main hardware architecture for AI computation. Because of their high power consumption and large size, it is necessary to consider other architectures to perform AI computing in outer-space where size, weight, power, and cost (SWaP-C) are tightly constrained. One such architecture is the Advanced Micro Devices (AMD) Versal Adaptive Compute Acceleration Platform (ACAP), which can achieve acceptable AI throughput at a lower power and size compared to a GPU. As the Versal ACAP gets used in space applications, it is necessary …

“Courage, Sisters. Your Living Is The Stuff Of Freedom”: Women In The Camden 28, 1971-1973, Abbigail Madeline Ealer

Theses and Dissertations

This historical study investigated the role and experiences of the ten women in the Camden 28, which was a group of Catholic Leftists who raided the draft board in Camden, NJ in 1971 to protest the Vietnam War. In utilizing a myriad of sources from archival collections through scarcely seen personal ephemera to correspondence with individuals connected to this case, this thesis demonstrated the importance of these women to the planning and execution of the raid as well as their significance to the outcome of the trial in 1973. It also showed the need for targeted scholarship on them. Furthermore, …

Who Moderates? A Polycentric Framework For Allocating Regulatory Responsibility In Online Content Moderation, Farh A. El Wishi

Theses and Dissertations

The question of who is responsible for content moderation on the internet remains one of the key topics relating to internet governance. Legislation has been adopted, platforms have utilized self-regulation methods, and users have flagged and reported content, all often happening simultaneously, yet rarely according to any coherent principle for deciding which actor should bear primary responsibility for which aspect of the problem. This research argues that the absence of a principled allocative framework is the central governance failure of the internet's regulatory history, and that addressing it requires a structured distribution of regulatory responsibility across the three actors who …

Modeling The Spread Of Competing Narratives In Multimodal Social Media Network, Mayor Inna Gurung

Theses and Dissertations

Social media has fundamentally transformed how narratives are produced, contested, and disseminated, enabling competing interpretations of the same event to spread rapidly across networked populations. Understanding how narratives gain traction over others in these environments is critical for addressing misinformation, supporting informed public discourse, and designing effective counter-messaging strategies. Yet existing research largely treats narrative propagation as a single-process phenomenon and focuses predominantly on textual data, overlooking both the competitive dynamics between opposing narratives and the growing role of visual symbolic communication in shaping how narratives are received. This dissertation addresses these gaps through a multi-platform, multimodal framework applied to …

British Subjects "Of Ye Jewish Religion": The Negotiated Identities Of The Levy-Franks Family, Laura Miriam Drake

Theses and Dissertations

Through a series of determined choices over sixty-five years, the Levy-Franks family blended their religious identity as Jews with their claimed British socio-political identity to achieve economic success in eighteenth-century colonial New York. Through colonial records, newspapers, legal petitions, portraits and, most significantly, the letters of Abigaill Levy Franks, this dissertation examines the family’s actions taken to create a blended identity, despite the potential threat that their participation in the broader British Atlantic world posed to their religious selves. During a time in British history when religious identities were at the forefront of political debate, the Levy-Franks family created a …

Living Doll: Puppetry, Performance, And The Art Of Greer Lankton, Madison Lee

Theses and Dissertations

This thesis argues that puppetry is the animating logic of Greer Lankton's practice. Drawing on archival evidence—including letters, planners, and drawings—it recovers an engagement with puppetry spanning childhood through her final years, and applies puppet theory to argue that Lankton understood selfhood as something made, not given.

“One Object Yields Both Grief And Joy”: Death In Elizabeth Cary’S The Tragedy Of Mariam (1613), Valeria Suprunova

Theses and Dissertations

This thesis argues that the dialog between early ancient Roman and early modern English traditions of death and dying helps illuminate the complex relationship between tyranny and death in Elizabeth Cary’s The Tragedy of Mariam (1613) and that death is an inextricable and dynamic element of the text.

They Returned Fighting: World War I, Disillusionment, And The Remaking Of African-American Political Life In New York City, Michael Frank

Theses and Dissertations

They Returned Fighting examines how Black New Yorkers used World War I service, wartime activism, and postwar protest to press claims to citizenship and democracy, even as racial violence, discrimination, and contested public memory exposed the limits of that belonging in New York City and the United States.

A Special Place In Hell: The Iconography Of Judgment In Twelfth-Century Sculpture And Manuscript Illumination, Nina Piper

Theses and Dissertations

While art historians have focused on the meaning of individual scenes of the Last Judgment and collections of “monstrous” images, this thesis considers images of Hell and its inhabitants as a single subject. It investigates the space of Hell itself and the beings most closely associated with it—whether or not they are depicted within the space of Hell—to identify iconographical consistencies across those images. In addition, this thesis draws upon material evidence from the medieval world to interpret images of Hell, the Devil, demons, and the damned in new ways, identifying connections between the imagery and what artists and other …

An Experimental Study On Turbine-Based Energy Harvesters For Thermal Underwater Gliders, Stephen Edward Coster

Theses and Dissertations

Buoyancy-driven underwater gliders have been optimized for long-duration missions primarily for continual monitoring of the ocean’s water column. However, longer missions and higher-powered sensors have increased the energy requirements of gliders. While current solutions aim to increase battery capacity, the development of energy-harvesting systems (EHMs) could greatly improve mission capabilities in both ability and duration. This thesis discusses the experimental testing of an underwater glider with an EHM as detailed in the theoretical study, “Development of a Turbine-Based Ocean Thermal Energy Harvesting Mechanism Applied to the Underwater Glider” by Hongbo Hou, PhD. The rear-mounted turbine captures energy using the kinetic …

Preserving The Untold Stories: Leveraging Emerging Technologies (Ai And Machine Learning) For Archiving Hidden Histories Of Children And Families Impacted By The Little Rock School Integration Crisis, Oluseyi Noah Adebanjo

Theses and Dissertations

This thesis challenges the dominant narrative of the Little Rock School Integration Crisis by recovering the hidden histories of families and siblings who made integration possible but have been systematically overlooked by historians. While existing scholarship focuses on the Little Rock Nine as individual heroes, this research demonstrates that integration was fundamentally a family crisis requiring collective decision-making, economic sacrifice, and multigenerational support networks. Through close reading of published memoirs, newspaper clippings, school board minutes, and original oral history interviews with Phyllis Brown and Dr. Sybil Jordan Hampton, this study reveals how approximately 200 eligible families were systematically reduced to …

Mscl-X: Meta Supervised Contrastive Learning With Gaussian Prototypes For Robust Few-Shot Open-Set Modulation Classification, Emmanuel Mawuli Agbator

Theses and Dissertations

Automatic modulation recognition has found its way into the core modern-day wireless communication systems whereby intelligent receivers estimate signal formats without any prior coordination with the transmitters. Challenging situations arise in any working radio frequency environment for the conventional modulation recognition systems due to insufficient labeled data, rapidly fluctuating channel conditions, and appearance of plenty other unseen modulation types. Taken together, these challenges raise questions concerning the ability to institute learning frameworks that could perform well on few-shot and open-set conditions. Hence the thesis attempts to address the same by proposing two complementary learning-based frameworks for few-shot open-set modulation recognition …

Securing Or Securitizing? Unveiling The Role Of Securitization “Audience” In Israel’S 2007 Bombing Of The Syrian Nuclear Site., Dunia Essam Hassanin

Theses and Dissertations

This thesis examines the 2007 Israeli bombing on Syria's Al-Kibar nuclear reactor through the lens of securitization theory, concluding that intelligence served as crucial audiences in legitimizing the operation. Building on the Copenhagen School's paradigm, which defines securitization as the process by which actors build issues as existential threats necessitating extreme measures, this study fills a critical theoretical gap: the underdeveloped role of the audience. While classic formulations focus on public approval, this study suggests a more sophisticated notion of the Political Intelligence Audience: intelligence agencies that validate and operationalize securitization moves. The concept contends that groups such as the …

Reconfiguring The Category Of 'Sudan' Through The Literary Field: Representation, Disposability, Ambiguity And The 'Magical' In Four Post-Colonial Novels (2002-2022), Mourad Farahat

Theses and Dissertations

In this thesis I shall argue that contemporary African literature, with ‘’both its ethnographic imagination and anthropological complexity’’ (Orock, 2022, p.3), its use of ‘disruptive’ characters, and its focus on the embeddedness of the ‘collective’, the ‘common’ and the ‘vulgar’ in the personal (Mbembe, 2003), may help us mitigate some social scientific limitations on the study of Africa, and may aid us in understanding relations of power within the post-colony. I seek to show how contemporary Sudanese literature has already moved beyond the fixed social categories, lines, and limits which dominate some of the social scientific literature on Sudan. Literature …

Between Borders And Bodies: Sovereignty, Universality, And The Crisis Of Enforcement In International Law, Aliaa Riad Hassanien Aliaa Riad

Theses and Dissertations

Atrocities such as genocide and war crimes persist not despite international law, but within its very structure. Although international law is designed to protect humanity, it repeatedly fails to do so due to its inability to enforce its most fundamental norms. In the absence of enforcement, the law exists—but merely stands still. This failure stems from the structural contradictions embedded in the system—specifically, the tension between the principles of sovereignty and universality. As a result, international law has become a selective, politicized, and ineffective framework. Incidents such as the Rwandan genocide and the civil wars in Syria and Sudan demonstrate …

Commercial Off-The-Shelf Electronic Warfare Threats To Global Positioning System Receivers, Matthew P. Robinson

Theses and Dissertations

This research evaluates the feasibility of commercial-off-the-shelf (COTS) hardware developed into an electronic warfare (EW) system used to degrade or deny Global Positioning System (GPS) receivers. All 16 critical infrastructure sectors rely on GPS signals to operate safely and effectively. Millions of Americans rely on GPS signals and the services they provide in their daily lives, so the loss of these vital services would dramatically impact our society. Our nation’s reliance on the GPS network makes it a potential target for COTS EW threats. The ways and means to develop COTS hardware into EW systems to interfere with GPS receivers …

Writing Against The War Machine: Wiflred Owen's Poetic Challenge To World War I Pro-War Rhetoric, Elizabeth Woods

Theses and Dissertations

Wilfred Owen, a soldier-poet who fought in World War I, is often labeled an anti-war poet, with some claiming that he was against the war in its entirety. This thesis explores the opinion that Owen is not an anti-war poet but rather that he wrote against anti-pro-war rhetoric. This includes all types of pro-war rhetoric influential in England for recruitment purposes but mainly focuses on poetry that would be published in newspapers for everyday readers to see. Owen seems to specifically resist two types of pro-war rhetoric, the myth of the German barbarian and what he called the old lie. …

America The Not Yet Beautiful: Unfulfilled Promises In A Racist-Capitalist Society, Kaitlyn Tibbetts

Theses and Dissertations

This thesis draws from Langston Hughes’s poem “Let America Be America Again” to analyze four American novels that demonstrate the United States’s unfulfilled promises for lower-class individuals and minorities. The four novels examined in this thesis include: The Outsiders by S. E. Hinton, The Nickel Boys by Colson Whitehead, There There by Tommy Orange, and How the García Girls Lost Their Accents by Julia Alvarez. Utilizing theoretical frameworks such as social reproduction theory, intersectionality, and Burden-Shelly’s theorizations on racist-capitalist oppression, this thesis argues that the policies and systems that the U.S. is founded on are designed to primarily benefit economically …

Reawakening Waⁿdat: Community Research & Reclamation, Darcy Allred

Theses and Dissertations

The Wyandot(te) have undergone language dormancy due to settler colonial impacts of warfare, refugee relocation, forced removals, and U.S. assimilation projects. One of the most pressing priorities among our people today is reawakening our ancestral language, Waⁿdat. The common follow-up question is: how? Through the conduit of Waⁿdat language reclamation, this project grapples with the above question in collaboration with the Wyandot(te) community, and in adherence to the tribal sovereignty of the Wyandotte Nation. The project engages with diasporic perspectives, community-based pedagogy design, and tribally specific research protocols and policies. The living collective knowledgebase with which I engage in this …

The Cyclical Pattern Of Despair And Hope: T.S. Eliot’S Comedia, Danielle Russo

Theses and Dissertations

This thesis examines how T.S. Eliot is inspired by Dante’s Divine Comedy throughout his collection of poetry, which in turn creates his own version of the Comedia. Through this thesis, there is an exploration of three stages: Hell, Purgatory, and Paradise. By following the road map to paradise just as Dante did before him, Eliot creates a journey from the depths of hell provided by the end of the Great war towards the garden of paradise prior to the start of the Second World War, exploring themes of paralysis, terror, experience without meaning, and hope. Using excerpts across his span …

More Than A Seat At The Table: Examining How Psychological Safety, Identity Representation, And Leadership Accountability Impact African American Women In Global Workplace Environments, Shelbi Chandler

Theses and Dissertations

This qualitative phenomenological study examined the lived experiences of African American women working in corporate technology environments, with particular attention to psychological safety, representation, and systemic barriers to advancement. Despite increased organizational commitments to equity and inclusion, research continues to demonstrate that Black women encounter persistent intersectional barriers shaped by race and gender within professional settings (Erskine et al., 2021; Field et al., 2023; Roberson, 2019). Guided by Du Bois’s (2008) theory of double consciousness, Goosby Smith’s (2014a) Ubuntic inclusion framework, and appreciative inquiry (AI; Cooperrider & Whitney, 2005), this study explored how African American women interpret, navigate, and respond …

The Long Shadow Of The Boys In Blue: Civil War Memory & The Evolution Of Veteran Identity In Twentieth Century Pennsylvania, Alexander L. Barbolish

Theses and Dissertations

This thesis presents a case study of the transformation of veteran identity and civic culture in Northeastern Pennsylvania, tracing the profound shifts in the way Americans remembered war, commemorated sacrifice, and defined what it meant to be a veteran, from the turn of the twentieth century to the dawn of World War II. By examining the complex interactions and relationships between three distinct and overlapping generations of veterans—those of the Civil War, the Spanish-American War, and World War I—this study argues that veteran identity was neither static nor monolithic, but was continually renegotiated through commemorative practice, organizational culture, and public …

Staging Violence With Intentionality, Toby O'Brien

Theses and Dissertations

This thesis examines the role of the fight choreographer in the theatre while addressing the potential issues staged violence has in distracting an audience from the intended narrative of the play. Avoiding the instruction manual approach of stage combat in favor of expounding on the theory of violent entertainment, I have constructed a thesis that informs the reader of certain types of violence found in both classical and modern productions and have researched the psychological ramifications of violent spectatorship and the necessity for content acknowledgements as well as consideration for the performer’s well-being. By exploring the history of violent entertainment …

Optimizing Military Fighter Jet Selection: A Decision Analysis Approach For Nuclear-Capable Aircraft, Eni Kelechi Ofong

In adaptation to the continuously changing technology landscape and the necessity for enhanced deterrence capabilities, this study evaluates three potential aircraft: the legacy Panavia Tornado (PA-200), the widely deployed F-16 Fighting Falcon (F-16), and the advanced F-35 Lightning II (F-35). Each platform presents distinct advantages and limitations regarding operational performance, mission adaptability, cost-effectiveness, and long-term sustainability. To systematically assess these alternatives, the study employs various decision analysis frameworks, including Multi-Criteria Decision Analysis (MCDA), single dimensional value function …

Law As Performance: Sovereignty, Legal Indeterminacy, And The Chinese Private Security Industry, Alexandrya Pouliot

Theses and Dissertations

This thesis examines how the legal indeterminacy of international law facilitates state evasion of accountability through the use of private military and security companies (PMSCs) as proxies in extraterritorial operations. Focusing on China’s deployment of PSCs to safeguard Belt and Road Initiative (BRI) projects, it argues that ambiguities within the doctrines of attribution and responsibility under the Articles on the Responsibility of States for Internationally Wrongful Acts (ARSIWA) create a permissive legal environment that enables states to outsource coercive functions without incurring formal liability. Drawing upon Hobbesian Realist theory, Carl Schmitt’s concept of the sovereign exception, and insights from Critical …
