Going Live: How Twitch Appearances Shape Voter Perceptions Of Political Candidates, Leah H. Ross

Theses - ALL

This paper examines the persuasive power of political candidates appearing on livestreaming platforms as a campaign strategy for targeting younger, politically disengaged voters. Drawing on the theoretical frameworks of platform affordances, parasocial interaction, celebrity endorsement, and source credibility, it argues that the unique digital architecture of livestreaming sites creates media conditions distinct from traditional broadcast media and other social media. These conditions amplify parasocial experiences, telepresence, and flow, making audiences potentially more receptive to political messaging. The paper then situates livestream appearances within the broader tradition of celebrity endorsements and the growing influence of social media in campaign communication. It …

Kitchen As An Archive: Konkani Food, Memory, And Identity In India, Sanjana Sharma

Theses - ALL

The Konkani community has often struggled to find an effective way to preserve its culture. Colonial conflict, regional division, and diasporic migration have stood in the way of creating a unified identity. My thesis argues that Konkani cooking traditions comprising heirloom ingredients, conventional cooking tools, ceremonial food practices, and adaptable diaspora recipes constitute a vibrant and evolving repository. This makes the kitchen an essential yet overlooked space for cultural memory. Concentrating specifically on the Konkani communities in Karnataka, I explore how ingredients such as Kokum underscore an understanding of plant ecologies; how seafood sheds light on coastal traditions; how gendered …

Evidence For Environmental Stripping In The Coma Cluster, Richard T. Pomeroy, Juan P. Madrid, Conor R. O’Neill, Alexander T. Gagliano

Physics & Astronomy Faculty Publications

The stability and longevity of globular clusters (GCs) make them effective tracers of the dynamical histories of galaxies in cluster environments. We construct a catalog of 23,351 GC candidates in the Coma Cluster using imaging from the Hubble Space Telescope Advanced Camera for Surveys. We cross-match galaxy data from the SIMBAD, NASA/IPAC Extragalactic Database, and Sloan Digital Sky Survey archives to construct a galaxy sample and model their GC populations using the GC specific frequency. We find several galaxies with significantly smaller GC populations than expected from their luminosities, consistent with either tidal stripping or intrinsically low formation efficiencies. We …

Assessing Knowledge And Decision-Making In Basic Genomics Among Adolescents And Adults, Sidharth Masarur

Honors Scholar Theses

Background

Genetic testing and genomic sequencing are increasingly part of pediatric care, yet many adolescents and parents lack the knowledge needed to make informed decisions. Prior studies show gaps in understanding, even among highly educated families, raising concerns about the adequacy of consent and assent. Little is known about when youth begin to comprehend genomic sequencing and how this impacts their own genetic and genomic decision-making.

Objective

To assess baseline genomic knowledge among adolescents and parents, examine its influence on decisions about genetic testing and sequencing, and identify opinions on appropriate age thresholds for youth participation in testing decisions.

Methods …

Geometric Approaches To Memory Formation In Soft Matter, Gentian Muhaxheri

Dissertations - ALL

The primary focus of this dissertation is the development of a geometric framework for understanding memory formation in systems composed of interacting hysteretic elements, or hysterons. Using tools from bifurcation and catastrophe theory, this work provides a description of how complex memory behaviors emerge from the structure of the system's configuration space and the system bifurcations under external driving. As a concrete model system, we study networks of connected rubber balloons subjected to different inflation protocols. Under pressure control, the system maps naturally onto a Preisach-type system of non-interacting hysterons and exhibits return point memory. In contrast, under volume control, …

Scalable Advanced Control Of Building Hvac Systems Using Physics-Informed Machine Learning, Xuezheng Wang

Dissertations - ALL

Buildings account for approximately 40% of total energy consumption in the United States, with HVAC systems representing the single largest energy end-use. Advanced control strategies such as model predictive control (MPC), reinforcement learning (RL), and differentiable predictive control (DPC) have demonstrated significant energy savings in individual studies, yet their widespread adoption remains limited by the lack of scalable, control-oriented dynamic models, the absence of consensus on control strategy selection, and the gap between single-zone research and multi-zone real-building deployment. This dissertation addresses these barriers through an integrated research program spanning physics-informed machine learning (PIML) model development, advanced control evaluation, and …

Symmetries Of Legged Locomotion: Theory And Applications In Animals And Robots, Jiayu Ding

Dissertations - ALL

Legged locomotion in animals and robots is naturally modeled as a hybrid dynamical system: smooth body evolution is repeatedly interrupted by discrete contact events such as touchdown and liftoff. Although symmetry is a powerful organizing principle in smooth dynamical systems, a comparably systematic symmetry framework for hybrid legged locomotion remains underdeveloped. This dissertation develops such a framework for a scoped class of periodic hybrid locomotion models and uses it to relate theoretical gait analysis, animal locomotion studies, and robotic gait generation. The dissertation first extends symmetry notions from autonomous dynamics to hybrid legged systems and distinguishes symmetries of the hybrid …

Global Invertibility Of Sobolev Mappings And Energy Minimizers With Prescribed Jacobian, Sabrina Traver

Dissertations - ALL

We prove two main results at the intersection of Geometric Function Theory and Nonlinear Elasticity. The first is a Sobolev variant of the Inverse Function Theorem, which generalizes a famous result of John Ball. It uses Classical Sobolev Theory as well as the Degree Function, which was initially a topological tool. The second result is the existence and uniqueness (up to rotation) of a radially-symmetric minimizer for Sobolev mappings with prescribed Jacobian. This result generalizes recent work of André Guerra, Lukas Koch, and Sauli Lindberg.

Dg Algebra Techniques For Tor Algebras And Edge Ideals, Desiree Martin

Dissertations - ALL

This thesis is comprised of two projects. The first is individual work where I use semifree Gamma-extensions to show, for an ideal I with infinite projective dimension over a Noetherian local ring R, there exists a splitting morphism from a Tor algebra Tor(R/I,R/I) to the exterior algebra of the R/I-free summands of the conormal module. In particular, when the conormal module is free over R/I, we see that the exterior algebra of the conormal module splits completely from Tor(R/I,R/I) as algebras. For the second project my collaborators, Hugh Geller and Henry Potts-Rubin, and I completely classify all trees and cycle …

On Compact Quasi-Einstein Metrics Of Constant Scalar Curvature, Eric Morgan Cochran

Dissertations - ALL

This thesis concerns a generalization of Einstein manifolds called quasi-Einstein manifolds. These manifolds are a triple $(M,g,X)$ where $(M,g)$ is a Riemannian manifold, and $X$ is a smooth vector field on $M$. Quasi-Einstein manifolds are of interest in general relativity, where a special class of quasi-Einstein manifolds are known as near horizon geometries. They are also related to Ricci solitons, which are self-similar solutions of the Ricci flow. In the first set of results in this thesis, we study the existence of Killing fields on compact quasi-Einstein manifolds. In particular, we prove an equivalence between compact quasi-Einstein manifolds of constant …

The Impact Of The U.N. Convention On The Rights Of People With Disabilities On Education For Students With Disabilities In China: A Case Of Non-Compliant Effectiveness With International Law, Renci Xie

Dissertations - ALL

This dissertation empirically investigates the impact of the United Nations Convention on the Rights of Persons with Disabilities (CRPD) in China, with a particular focus on Article 24, the right to education. Using a mixed-methods approach, this dissertation addresses two central questions: whether and how Article 24 has influenced Chinese national policies on inclusive education; and whether and how the Chinese law that promotes inclusive education has impacted the lived experiences of students with disabilities in seeking educational accommodations. To examine changes in Chinese national policy, the study employs Critical Discourse Analysis of disability-related education laws and regulations. This analysis …

A Study Of The Links Between Denudation, Lithology, And Tectonics In The Tropical Andes, Helbert Garcia-Delgado

Dissertations - ALL

Landscape evolution in the tropical Northern Andes is governed by complex interactions between tectonic deformation, climatic shifts, and bedrock lithology. Standard geomorphic models often struggle to capture the full spectrum of these processes, particularly in active orogens where topographic steady state is frequently challenged by variable sediment dynamics and deep weathering. Understanding how these factors dictate landscape responses over different timescales is critical for interpreting the relationship between landscape evolution and surface processes of tropical mountain belts. This dissertation utilizes a combination of cosmogenic nuclide dating, numerical modeling, and subsurface borehole analysis to examine the structural, climatic, and lithological controls …

Development Of Dual-Stimuli Responsive Polymer-Coated Gold Nanoparticles And Their Surface Engineering Via Polyelectrolyte Layer-By-Layer Assembly, Buddhini Chathurangi Nugaduwa Vithanage

Dissertations - ALL

The modification of nanoparticles with combinations of low critical solution temperature (LCST) polymers and polyelectrolyte (PE) layers is studied. Three n-isopropylacrylamide-co-acrylamide polymers were synthesized in which charges could be varied from neutral, to negative or positive by way of incorporating poly acrylic acid (pAAc) or poly 4-vinylpyridene (p4VP) units. Polymerization centered around a disulfide initiator, which when reduced produced two polymer chains and a convenient linkage to gold NPs (NPs). The resulting LCST-NPs conjugates possessed sharp phase changes at critical temperatures (TC), while the incorporation of pAAc or p4VP allowed for tuneable charges and pH sensitivity. Studies with 1H-NMR and …

Avicenna On Non-Rational Voluntary Motion, Hamed Shirmohammadi

Dissertations - ALL

This dissertation investigates Avicenna’s theory of non-rational voluntary motion. Avicenna’s most significant innovation in this domain is his theory of the internal senses, and in particular, his account of the estimative faculty (wahm) and its proper objects, the intentions (ma'nā). Intentions are non-sensible features of perceived particulars—such as the hostility of a wolf—that carry evaluative significance for the perceiving animal. This dissertation argues that understanding the nature of intentions is the key to explaining how a non-rational animal can pursue goals through relatively complex courses of action. Avicenna recognizes two ways in which intentions are acquired: through instinct and through …

"I Just Wanted To Help": Certified Recovery Peer Advocates And Disconnected Labor, Rosie Benser

Dissertations - ALL

This dissertation examines the remaking of the recovery industry via the rise of Certified Recovery Peer Advocates (CRPA), or recovery peers, and the conditions that enable and constrain their labor. Peer Based Support Services (PBSS) was professionally recognized in the substance use disorder (SUD) treatment field starting in the early twenty-first century through federal grants for the underinsured and the ability to submit services for Medicaid/Medicare insurance repayments. As a result, CRPAs are especially present in low-income communities, dispatched to serve people seeking recovery from SUD with a mandate to “have conversations about change.” Drawing from in-depth interviews, participant observation …

A City’S Neglectful Past: Young Black Mothers And The Creation Of A Reproductive Health Crisis In The Urban North 1900 - 2005, Semaj Imane Campbell-Blakes

Dissertations - ALL

"A City’s Neglectful Past: Young Black Mothers and The Creation of A Reproductive Health Crisis in the Urban North 1900‐2005" examines how the promise of northern liberalism concealed enduring forms of racial inequality in reproductive health. Centering Syracuse, New York, a city long celebrated for its nineteenth-century abolitionist legacy, the project reveals how its twentieth-century institutions expelled pregnant Black girls from schools, criminalized their sexuality, and oversaw some of the highest Black infant-mortality rates in the nation. Through this lens, Syracuse becomes a case study in the contradictions of progressive reform, where liberal ideals coexisted with structural neglect and moral …

How Institutions Of Higher Education Leverage Information Technology To Navigate In A Dynamic Environment: The Case Of Alternative Credentials, Sarah J. Williams

Dissertations - ALL

This research examines how higher education leverages information technology (IT) to mitigate the uncertainty of enrollment volatility in a dynamically shifting landscape. The strategic alignment model (SAM), a theory of strategic alignment of business and information technology, was applied to analyze how microcredential programs in higher education institutions address this uncertainty. Publicly accessible information was collected to develop cases from 15 institutions of higher education alternative credential programs. The collected evidence was assessed to discern how leveraging technology generates value related to the strategic mission of the institutions. The hallmarks of excellence standards, developed by the University Professional and Continuing …

Implementing A Buddy System To Enhance Float Pool Nurses’ Experience And Unit Integration, Nancy Kairia

Doctoral Projects

Float pool nurses play a vital role in maintaining hospital operations; however, they often experience role ambiguity, inconsistent integration, and reduced psychosocial empowerment, which may negatively influence engagement and retention. This Doctor of Nursing Practice project implemented and evaluated a structured buddy program designed to enhance psychological empowerment among float pool nurses in a large academic medical center. Guided by Gretchen Spreitzer’s Psychological Empowerment Framework, the project examined changes across four domains: meaning, competence, self-determination, and impact. A pre-post design was used to assess outcomes before and after implementation. Five nurses completed the preintervention survey; of these, four completed the …

Belonging, Identity, And Agency: A Qualitative Study Of Muslim Students In U.S. Higher Education, Amir Duric

Dissertations - ALL

This dissertation examines the lived experiences of Muslim students in U.S. higher education, focusing on how they navigate identity formation, search for belonging, and exercise agency within two predominantly white institutions (PWIs) in the Northeast. Drawing on 40 semi-structured interviews and four months of fieldwork, the study demonstrates how Muslim students navigate not only their religious identity and practices in secular contexts but also how the racialization of their Muslim identity is shaped by U.S. foreign policy and the Global War on Terror. Three central findings emerged from the data. First, Muslim students demonstrated sustained and deepening religious commitment through …

Hands On: An Exploration Of Techne Via Everyday Embodied Practices, Molly Mcconnell

Dissertations - ALL

In the field of Rhetoric, Composition, and Writing Studies (RCWS), techne has been a longstanding focus of the field, notably as it pertains to our understanding and practice of rhetoric and how we teach writing and rhetorical practices. Some scholars have focused on techne as it is taught in the writing classroom; others have focused on how rhetoric is understood and applied in the classics. My research builds on previous work by considering techne in connection to embodied practices. I argue that discussions of techne have thus far focused on individual learning, especially in relation to composition and rhetoric. In …

Co-Designing Sweettexts: An Intake-Driven Sms Intervention To Reduce Free-Sugar Consumption In Preschoolers, Bervelyn Asantewaah Addo

Theses - ALL

Abstract Introduction: As early childhood represents a crucial window for establishing lifelong dietary patterns, excessive intake of sugary foods and beverages during this period may result in long-term adverse health outcomes. Intake levels continue to exceed recommended guidelines, and disparities within and across race and low-income population groups persist. Given these disparities, targeted interventions developed to consider the unique needs, preferences, and cultural differences in diverse population groups are essential to enhance health and well-being. The purpose of this research was to develop the content of the "SweetTexts", a text-message-based intervention to reduce the intake of free sugar among preschool-aged …

Apparatus Of Relief: On Sustained Exhaustion, Jiayue Yu

Theses - ALL

This thesis examines how contemporary capitalism manages a shared condition of exhaustion—the accumulation of stress, alienation, and mental fatigue—by offering calibrated forms of relief that leave its underlying causes intact. Approaching exhaustion as a collective and structurally produced condition, I make photographs that trace how it is softened and normalized within the spaces we inhabit and move through in our daily lives. Central to the project are what I describe as “apparatuses of relief”: infrastructural features embedded in public and semi-public spaces that are designed to regulate affect and soothe nerves. Operating beneath the surface, these elements promise momentary relief …

Agency At The End Of History: Time, Terrorism, And Technologies Of Innocence In Engaging The Far Right, Gabriel Gr Herring

Theses - ALL

This thesis explores the way political rhetorics of time, morality, and political violence play out in visual representations of the far right in the United States via maps. In Out of Joint: Power, Crisis, and the Rhetoric of Time, Nomi Claire Lazar argues that governments and political movements use temporal-rhetorical frameworks to generate political legitimacy by associating their movement with time, which is generally understood as natural. I argue that every temporal-rhetorical frame also implies a set of moral codes which are understood to be materially true, despite the fact that our experiences of time are only ever aim-dependent and …

The Role Of Creatine Supplementation On Neuromuscular Function, Mark Petry

Theses - ALL

This study examined the effects of short-term high-dose creatine monohydrate (CrM) supplementation on neuromuscular and corticospinal function in healthy adults. Creatine is widely recognized for its role in enhancing muscular performance and energy availability, yet its short-term effects on neural and neuromuscular outcomes remain unclear. The purpose of this investigation was to determine whether three days of CrM loading would influence maximal voluntary contraction (MVC) peak torque, corticospinal excitability (CSE) measured via transcranial magnetic stimulation (TMS)-induced motor evoked potential (MEP) amplitude, muscle cross-sectional area (CSA) and muscle quality via echo intensity (EI). Nine healthy creatine-naive adults completed a repeated-measures design …

Remembering Return: Diasporic Identity And The Tabom Community In Accra, Elizabeth Akosua Adobea Danso

Theses - ALL

This thesis examines the historical and cultural significance of the Tabom community in Accra, Ghana, as a case study in diasporic identity, collective memory, and return migration. As descendants of Afro-Brazilian returnees who arrived in the Gold Coast in the early nineteenth century, the Tabom occupy a distinctive position within Ghana's social and historical landscape, navigating multiple cultural affiliations across Brazilian, Yoruba, Hausa, Ga, and Ghanaian identities over generations. Drawing on ethnographic research conducted in Jamestown, Accra, including semi-structured interviews, participant observation, and oral history collection, this thesis argues that Tabom identity is neither static nor reducible to a singular …

Nitrogen And Phosphorus Fertilization Shifts Fungal And Bacterial Community Composition And Functional Groups In Temperate Forest Soils, Caroline Frances Plecki

Theses - ALL

Anthropogenic nitrogen (N) deposition is known to alter nutrient limitation in temperate forests, yet belowground microbial responses under shifting phosphorus (P) and N+P availability remain unclear. Using a long-term N × P fertilization experiment (MELNHE), we quantified fungal and bacterial community responses across organic and mineral soil. Nutrient additions restructured community composition without changing alpha diversity, indicating taxonomic turnover rather than richness loss. Nitrogen reduced ectomycorrhizal (EM) dominance and increased the relative abundance of saprotrophic fungi in the organic soil layer, including declines in nitrophobic taxa such as Cortinarius. Phosphorus structured fungal guild ratio non-linearly, with EM fungal dominance maximized …

Quasiparticle Poisoning Of Superconducting Fluxonium Qubits, Kesavan Manivannan

Dissertations - ALL

Superconducting qubits based on Josephson junctions have emerged as a leading hardware platform in the quest to realize large-scale quantum computers. However, qubit decoherence remains a major hurdle on the path toward fault-tolerant quantum computing. In particular, excess quasiparticle (QP) excitations constitute a significant source of dissipation in superconducting quantum devices. The empirically observed QP density in these systems is orders of magnitude larger than that predicted by Bardeen-Cooper-Schrieffer (BCS) theory. Moreover, QP poisoning due to high-energy particle impacts can cause correlated errors that simultaneously affect multiple qubits, thereby impeding quantum error correction. Although QP-induced decoherence has been extensively studied …

'Realizing' Information Literacy: A Philosophical Argument, Jeongbae Choi

Dissertations - ALL

Despite more than half a century of scholarship, the information literacy (IL) field continues to face unresolved tensions over its definition, theoretical foundations, disciplinary boundaries, and relationship to power and social structure. This dissertation argues that these tensions are not isolated problems but interconnected aporias that reveal constitutive features of the field, and that resolving them requires a philosophically grounded reconceptualization. The dissertation proceeds across three phases. Study A conducts a comprehensive critical review of over 600 publications in the IL literature, adopting an aporetic lens to identify six constitutive aporias: truth, knowledge and data, information behavior, genericism versus contextuality, …
