How Temporal Integration And Complexity Drive Musical Enjoyment, August Miller

Dissertations, Theses, and Capstone Projects

Music is a type of aesthetic stimulus that unfolds dynamically over time. Combining approaches from previous research on musical preferences and research on spatial integration as a driver of visual aesthetic appreciation, we investigated how the integration of musical percepts over time influences listener enjoyment and the level of agreement between the enjoyment ratings of each listener. We used a DNN tool to quantify temporal dependencies in 32 music clips and also computed complexity scores for them. Subjects listened to each music clip while using a rotating dial to provide a continuous enjoyment rating, changing the dial’s position at the …

Scaling Limits Of Critical Observables Through The High Dimensional Incipient Infinite Cluster, Pranav Chinmay

Dissertations, Theses, and Capstone Projects

We give a general construction of the incipient infinite cluster in high dimensional percolation, and use it as a decoupling tool to rigorize geometric heuristics for analyzing the asymptotics of observables at criticality. Examples include demonstrating the limiting distribution of the chemical distance and full-strength asymptotics for k-point functions, which constitute foundational inputs for scaling limit results associated to critical clusters.

Implicit Attitudes Toward Hearing Aid Visibility: Conspicuous Versus Inconspicuous Hearing Aid Colors, Orly R. Ames

Dissertations, Theses, and Capstone Projects

Hearing aid stigma remains a significant barrier to treatment uptake, with device visibility frequently identified as a contributing factor. Although prior research has examined visibility in relation to hearing aid size and style, the role of color as a distinct aesthetic dimension has not been systematically investigated. The present study assessed whether hearing aid color affects implicit and explicit attitudes toward hearing aids and whether such evaluations differ across contexts. Twenty-six adults who were not current hearing aid users participated in an online quantitative multi-method study consisting of an Implicit Association Test (IAT) and self-report questionnaires. The IAT measured implicit …

Computational Insights Into Nucleosome Dynamics In Epigenetics Using Molecular Dynamics Simulations, Rutika Patel

Dissertations, Theses, and Capstone Projects

Nucleosome core particles (NCP) are the building blocks that form a highly organized and compact chromatin structure. Nucleosomes package DNA in the nucleus of eukaryotic cells. The NCP consists of about 147 base pairs of DNA wrapped around the histone octamer, with 1.65 superhelical turns in a left-handed manner. The histone octamer is composed of two copies of H3, H4, H2A, and H2B. Together with histone H1 and linker DNA, they further assemble into a higher-order chromatin structure. The nucleosome complex is stabilized by electrostatic interactions between positively charged histone residues and the negatively charged DNA backbone. To effectively access …

Enhancing Ecological Validity In Speech-In-Noise Testing: Integrating Virtual Reality For A Multisensory Audiological Experience, Paulina Lee

Dissertations, Theses, and Capstone Projects

Despite the remarkable advances in hearing healthcare technology, the speech recognition tests used in routine clinical audiological assessment have remained essentially the same for decades.  Monosyllabic word recognition tests in quiet, such as the Northwestern University Auditory Test No. 6 (NU-6; Tillman & Carhart, 1966), have served as the audiology field’s default measure of speech understanding.  Modern speech-in-noise (SIN) tests, such as the QuickSIN (Killion et al., 2004), have emerged, yet they remain auditory-only, leaving an unignorable gap between what clinical tests measure and how patients communicate in daily life.  The present study examined whether pairing a standard SIN test …

Imagination And The Self: A Cross-Cultural And Cross-Disciplinary Study, Qianyi Qin

Dissertations, Theses, and Capstone Projects

This dissertation is an interdisciplinary investigation of the imagination and the self that engages with cognitive science, philosophy of mind, Buddhism, ethical theories, and a variety of perspectives from Asian and Western philosophy. I address the following questions in three interrelated chapters. First, what does it mean for the self to appear in imagination? In Chapter 1, against certain narrow understandings of the self in philosophy of language, I build a multidimensional model of the self in imaginative experiences to capture the rich phenomenology, drawing on empirical findings on memory and imagination. Second, can the self be removed from imagination? …

No Reply: The Exclusus Amator Through Ancient And Modern Love Poetry, Ayla Wing

Dissertations, Theses, and Capstone Projects

This thesis examines the exclusus amator, or “shut-out lover” trope as it appears in Greek and Roman texts, surveying the many examples of this motif and picking out its main elements: Intense Pain, Strong Emotions, Rejection, Interaction with the Door. It also notes the universality of the trope (anyone of any sexuality from any walk of life can be an exclusus amator) and the many references to the motif in other types of ancient media, including in graffiti, which shows that the exclusus amator was a real-life occurrence. This paper then examines modern songwriting, a genre chosen for its similarities …

Gramsci’S ‘Democratic Philosopher’ And The Concept’S Foundations In Marxian Social Ontology, Eli Recht-Appel

Dissertations, Theses, and Capstone Projects

This thesis deals with the term ‘democratic philosopher’ from Antonio Gramsci’s Prison Notebooks. In order to lay the groundwork for my distinct interpretation of the ‘democratic philosopher,’ I begin by providing an overview of Gramsci’s theory of the role of intellectuals in civil and political society. I then argue that the ‘democratic philosopher’ emerges from Gramsci’s typology of intellectuals but is a category which is both temporally and ontologically distinct from his more well-known concept of ‘organic intellectuals.’ ‘Organic intellectuals,’ intellectuals who co-develop alongside their fundamental social group or class, occupy a variety of cultural and political roles in …

The Maghrebi Silk Road: A Medieval Exploration, Malak Ouammou

Dissertations, Theses, and Capstone Projects

The Maghrebi Silk Road: A Medieval Exploration is an interdisciplinary historical examination of a variety of intellectual and material cross-cultural interactions and connections between Asia and the Maghreb from 900 to 1492. It primarily revolves around agriculture, sericulture, and immaterial and material culture, with an emphasis on knowledge production and dissemination. In it, I focus on the Mediterranean endpoint of the Silk Road network, illustrating the Maghrebi Silk Road through an exploration of various case studies such as rice, silk, and storytelling that demonstrate the role of and the extent to which these “secondary” Silk Road routes existed and were …

Unrepresentable Objects: Neoliberalism In The Contemporary Novel In French, Alicen Marie

Dissertations, Theses, and Capstone Projects

This dissertation operates at the intersections of textual analysis, political theory, psychoanalytic theory, and aesthetics to investigate the prevalence of uncanny imagery in ten examples of contemporary fiction, while also interrogating the notion of the uncanny as a category of analysis. Entitled “Unrepresentable Objects: Neoliberalism in the Contemporary Novel in French,” it examines a group of novels by Marie Darrieussecq, Virginie Despentes, Marie NDiaye, and Linda Lê, published in France between 1993 and 2017. These novels share an aesthetic of hauntedness and breakdown, incongruous affect, and a continual presence of the uncanny; they depict a world split from history and …

Hip-Hop Hypocrisy: How Rap Music Culture And Its Lyrical Obsession With Luxury Fashion Compromises Black America, Jeffrey Ampratwum

Dissertations, Theses, and Capstone Projects

Black creative thought is often regarded as a secondary means of expression, particularly within a meritocracy like the United States of America. Many Black intellectual thinkers and writers undoubtedly communicated with a style and prose that was widely understood amongst people of the culture. One of these creative communicating styles is the art of hip-hop and the use of language to tell a story. Born out of struggle in the 1970s, this musical derivative from funk, soul, and jazz penetrated the inner city communities and forced the upper class to listen to words from Black artists. Hip-hop initially represented four …

Algorithmic Problems In Automorphic Orbits Of Free Groups, Siobhan B. O'Connor

Dissertations, Theses, and Capstone Projects

One of the fundamental problems in the field of combinatorial group theory is telling when two group presentations represent isomorphic groups. Since applying a free group automorphism to the set of relators of a presentation gives an isomorphic group, we want to be able to quickly decide when looking at a relator whether a given word can be sent to it via an automorphism. We give a hands-on introduction to the automorphisms of free groups using patterns of colored beads. We show that you can make this decision correctly in constant time on average by looking for "orbit-blocking" words that …

Monsters In The Gutter: Queerness And Family In Graphic Novels, Maren Beriss

Dissertations, Theses, and Capstone Projects

In this thesis I read two graphic novels together: My Favorite Thing is Monsters by Emil Ferris and Black Hole by Charles Burns. Although the stories are quite different, they mirror each other quite closely: Burns’ story takes place in a homogenous suburb; Ferris’ is set in a diverse part of Chicago. Both deal with what it means to be a monster, but in different ways. Ferris has a clear framework of the different kinds of monsters – good, bad, and villager – which is at times helpful but often too narrow. Yet reading Burns with this lens in mind …

Urban Sacred Grove: A Visioning For Collective Care, Preservation, Environmental Justice, And Resilience, Oluwadara A. Ojugbele

Dissertations, Theses, and Capstone Projects

My capstone explores how the concept of sacred groves—a community-based practice of conserving forest areas for cultural, spiritual, or religious purposes—can be reimagined as a framework for urban environmental stewardship and community care. Sacred groves have historically varied across time and place but consistently serve as protected spaces that honor divine forces, ancestors, and community values. In the Yoruba context, groves demarcate lush forests as abodes for oriṣas (divine forces) and spiritual beings, often containing shrines and artifacts that embody cultural beliefs. My capstone draws on the sacred grove concept and aims to illustrate how urban communities might adopt sacred …

Race And The Enduring Logic Of Exclusion In U.S. Immigration Policy, 1882–2025, Kejda Nikollaj

Dissertations, Theses, and Capstone Projects

This thesis examines how immigration law in the United States has historically functioned as an instrument of racial exclusion and argues that this logic continues to shape contemporary policy and enforcement. Although overtly racist laws such as the Chinese Exclusion Act (1882) or the National Origins Act (1924) have long been repealed, their underlying rationales and structures continue to survive under the modern language of legality, security, and national interest. This study argues that restrictive immigration policies tend to emerge when racial and social insecurities intersect, allowing old hierarchies to be revived under new legal justifications. Through a comparative historical …

Erosion And Accretion: Mobilities Of Sand, People, And Memory At Queer Riis Beach, Jah Elyse Sayers

Dissertations, Theses, and Capstone Projects

The People’s Beach at Jacob Riis Park on the Rockaway Peninsula of Queens, New York, is a vibrant place of queer and trans public-space placemaking—and especially Black and working class queer and trans placemaking. A distinct queer ecology emerges in the interplay of the dynamic movement of the barrier island, queer and trans—especially queer and trans Afro-diasporic—mobilities. This queer ecology, while articulated with, also defies and exceeds logics and workings of private property. In response to a convergence of pressures on Black, queer, trans, and working-class placemaking on the beach site in the 2020s, beachgoers have mobilized longstanding provisional socialities …

An Investigation Of The Impact Of Privacy On Sexual And Reproductive Health Using Reports On The 2010 Earthquake In Haiti, Jillian E. Myers

Dissertations, Theses, and Capstone Projects

In 2010, a massive 7.0 magnitude earthquake hit the capital city of Haiti, Port-au-Prince, causing great destruction of infrastructure and the devastating loss of about 316,000 lives and over a million homes. The earthquake destroyed agricultural production and clean water sources, causing severe resource scarcity along with the overcrowding in the relief camps. Following the earthquake, international aid organizations flooded into Haiti in an effort to help provide immediate relief. The relief efforts were unprepared and lacked coordination among each other to efficiently implement the needed aid services. Without strategic planning to ensure all people’s needs are met, women and …

Kanak-Ish Misfits: Queer Imaginaries, Racialized Borders, And The Politics Of Care In Berlin, Germany, Faruk Seref

Dissertations, Theses, and Capstone Projects

This dissertation examines queer Muslim experiences of border politics, racialization, and care in Berlin, Germany. By formulating bordering as a domineering and oppressive practice of boundary-making, I study how global bordering mechanisms shape and disrupt structures of care, caring, and being cared for. With an intersectional focus on race, gender, sexuality, and sex, I argue that borders are simultaneously materialized and challenged in varying localities, including the nightclub, the queer scene, the diasporic neighborhoods, and households. Ultimately, viewing collective care as fundamental to survival, healing, resistance, and building non-punitive lifeworlds, I theorize the counter-hegemonic practices of queers of color through …

Wageless By Design: Dependency In U.S. Visa Regimes, Cristina Ochoa Echeverri

Dissertations, Theses, and Capstone Projects

This capstone examines how U.S. dependent visa regimes create a population of migrants who are legally present but structurally excluded from paid work and independent legal status. Focusing on visa categories such as H-4, F-2, M-2, O-3, P-4, R-2, and TD, it argues that wagelessness is not incidental but structurally embedded in the legal design of temporary migration governance through employment restrictions, derivative legal status, and the tethering of dependents to a principal visa holder.

Using a qualitative, interpretive approach, this study draws on documentary and secondary sources as well as digital narratives from platforms such as Reddit. This capstone …

Mapping Nucleosome Stability: Linking Oncogenic Structural Alterations To Long-Range Allosteric Communication, Augustine C. Onyema

Dissertations, Theses, and Capstone Projects

The nucleosome core particle (NCP) is essential for chromatin structure and function, serving as the fundamental unit of eukaryotic chromatin. Oncogenic mutations in core histones disrupt chromatin dynamics, altering DNA repair and transcription processes. How DNA communicates with histones, and how this information propagates through the histone, has been suggested to be a cooperative process. Here, I investigate the molecular consequences of two mutations, H2BE76K and H4R92T, using 36 µs of all-atom molecular dynamics simulations on Anton2. I also characterize the kinetic correlation within histone/DNA domains via conditional activity (CONDACT) using the dihedral angle as our degrees of …

Electromagnetic Counterparts To Active Galactic Nucleus Disk-Embedded Binary Black Hole Mergers, Emily Mcpike

Dissertations, Theses, and Capstone Projects

The accretion disks of active galactic nuclei (AGN) are promising environments for producing binary black hole (BBH) mergers, which have been detected via gravitational waves (GW) with LIGO-Virgo-KAGRA (LVK). BBH mergers embedded in AGN disks are unique among GW formation channels in their generic ability to produce electromagnetic (EM) counterparts, via interactions between the merger remnant and the surrounding disk gas (though these are not always observable). While such mergers represent valuable multi-messenger sources, the lack of predictive statistical models in existing literature currently limits our ability to select possible EM counterparts with GW detections in archival data and in …

Gathering Knowledge, Sustaining Science: The Female Forager And American Mushroom Culture, 1880–1930, Madeline S. Dede-Panken

Dissertations, Theses, and Capstone Projects

Unearthing origins of modern mycophilia, this dissertation explores the mushroom mania which reverberated through American society at the turn of the twentieth century, empowering Anglo-American women in new ways. America’s largely forgotten first mushroom fad illuminates gendered negotiations of foraging culture and public science. Beginning in the 1880s, a remarkable cohort of women helped turn mushrooms from shunned, mysterious organisms into wholesome delicacies for culinary and intellectual enrichment. Female enthusiasts fostered a vibrant mushroom culture and nationwide network of mycophiles. Culinary applications and poisoning fears legitimized women’s presence in scientific endeavors, positioning mycology as vital female knowledge for public safety …

Parkinson’S Disease Phenotype Stratification Using Multiple Correspondence Analysis, Kelly Astudillo

Dissertations, Theses, and Capstone Projects

Parkinson’s disease (PD) is the second most common neurodegenerative disorder, with over 12 million people projected to be affected by 2040 (Dorsey et al., 2018). Deep phenotyping and stratification can provide useful information regarding PD pathogenesis and can aid in the  development of disease modifying therapies that aim to delay the progression or prevent the onset of neurodegeneration (Blandini et al., 2019; Smith & Schapira, 2022). Utilizing multivariate methods such as multiple correspondence analysis (MCA) permits for the simultaneous analysis of distinct data modalities. To the best of our knowledge, MCA has not been previously used to explore phenotype patterns …

Variational Methods For Semilinear Pdes With Dirac Singularities, Samuel J. Magill

Dissertations, Theses, and Capstone Projects

This dissertation utilizes a variational framework for semilinear elliptic equations in two dimensions with Dirac measure data. The central objects of study are equations of the form −ΔU = f(U) + Σ_j=1^N α_jδ_pj on bounded Lipschitz domains Ω ⊂ ℝ² with homogeneous Dirichlet boundary condition, and on a flat torus 𝕋², where α_j is positive for the Dirichlet setting and α_j is negative on the torus. Solutions are obtained by minimizing the restriction of an energy functional to an order interval determined by explicit sub- and supersolutions; the Euler–Lagrange equation is recovered …

A Predictive Coding Account Of Spatial Working Memory Following Prophylactic Levetiracetam Administration Prior To Traumatic Brain Injury, Omeima Mutwali

Dissertations, Theses, and Capstone Projects

Traumatic brain injury (TBI) symptom prevention and remediation is an important area of research that would benefit vulnerable groups, including active-duty and veteran soldiers. These patients can sustain penetrative forces in fields of combat or in training, which result in focal lesions that trigger inflammatory and degenerative processes in the brain. Both primary and secondary injuries are associated with changes to cognition, behavior and affective state. This disease poses increased risk of epileptogenesis, as well. Given these outcomes, prior research has evaluated levetiracetam (LEV) as a prophylactic treatment for seizures, cognitive deficits and negative emotionality. LEV acts as a presynaptic …

The Exception: Refugee Camps And Governmental Control, Kyle L. Mans

Dissertations, Theses, and Capstone Projects

This capstone study examines the relationship between governmental control and the state of exception in refugee camps. This connection is analyzed by examining the control mechanisms employed by the nation state to erode the sovereignty of the individual within a refugee camp space. This study also examines how humanitarian organizations contribute to the perpetuation of the state of exception and how their involvement facilitates further state control. Included in this capstone are two case studies that examine both Libya and Kenya as examples of governmental control on the sovereignty of refugees and migrants. This research contributes to the overall understanding …

Policing Sex Trafficking: 'They’Re Never Taught, You Know', Anila S. Duro

Dissertations, Theses, and Capstone Projects

Research shows that victims of sex trafficking are most likely to first come in contact with the police (Baldwin et al, 2011; Twigg, 2017) and at times police have not been able to categorize cases of prostitution as trafficking even when trafficking elements were very clear (Dank et al, 2017; Dempsey, 2017; Farrell & Cronin, 2015). Despite the legal definition of trafficking, the terms prostitution, sex work, and sex trafficking are sometimes used interchangeably by law enforcement, whereas at other times, these words refer to different sets of circumstances and have different criminalization outcomes.  Research in this area is limited …

The Evolution Of U.S. Geoeconomic Grand Strategy Toward China And South Korea’S Strategic Space: A Comparative Analysis Of Neomercantilist Types In The Trump And Biden Administrations, Hyungbo Kim

Dissertations, Theses, and Capstone Projects

This study examines the evolutionary trajectory of U.S. geoeconomic grand strategy toward China from the inauguration of the first Trump administration in 2017, through the Biden administration, to the second Trump administration launched in 2025, while exploring South Korea’s survival strategies in response. The findings confirm that U.S. foreign economic policy has radicalized into "Expanded Malevolent Neomercantilism," which moves beyond simple protectionism to weaponize global economic networks in the name of national security and exploit even allies.

According to the analysis, the U.S. progressed from the "Malevolent Neomercantilism" of Trump's first term, which focused on trade deficits, to the "Developmental …

A Data Analysis Study Of Temperature Based On California Cooperative Oceanic Fisheries Investigations (Calcofi) Data., Afsana Mimi

Dissertations, Theses, and Capstone Projects

This research presents an integrated analytical framework for predicting ocean temperatures using long-term observations from the California Cooperative Oceanic Fisheries Investigations (CalCOFI) data files. The study applies advanced data engineering and statistical modeling to assess how a variety of indicators, such as salinity, dissolved oxygen, key nutrients, and ocean depth shape oceanic temperature patterns along the California coastline. Using Microsoft SQL Server software for large-scale data integration and the R for statistical packages (R Core Team, 2025) for statistical computation, I developed and compared multiple regression models, including the ridge regression model, to evaluate the relative influence of physical and …

1d Crust-Magnetosphere Coupling Model For Magnetars, Kennedy M. Jeter

Dissertations, Theses, and Capstone Projects

Magnetars are the most extremely magnetized objects in the universe. Their strong magnetic fields generate high-energy magnetic flares with instantaneous luminosity that can outshine their host galaxy. Previous works have explored how Hall drift in the crust affects the dynamics of magnetic field lines in the magnetosphere. This work investigates how a change in the magnetosphere, such as a flare or an outburst, can excite Hall evolution in the crust. We investigate how the twisting and untwisting of magnetic field lines in a magnetar’s magnetosphere launches Hall waves through its crust using a one-dimensional numerical model. We use the Dedalus …
