Quiver Of Affine Monoid Of A Vector Space Over Finite Field, James Junie Chen Cleary

Dissertations, Theses, and Capstone Projects

In this paper, we study the quiver of the complex monoid algebra CAFF(n, q). There are n + 1 maximal subgroups of AFF(n, q), each isomorphic to AGL(k, q) for some 0 ≤ k ≤ n. Every irreducible representation of CAFF(n, q) arises from a character of CAGL(k, q) for a suitable k. Thus, we study two different approaches to classifying the characters of CAGL(k, q). Next, we compute the full quiver Q(CAFF(n, q)). Finally, we show that this quiver is a disjoint union of straight-line paths and that its basic algebra has radical square zero. Hence, it has finite …

Alive And Thriving: Ancestral Wisdom Usage Among Us Based Latine Clinical Social Workers In Psychotherapy Practice, Yaneth Lombana

Dissertations, Theses, and Capstone Projects

At a time when the United States is rolling back protections to vulnerable communities, this dissertation investigates experiences of Latine clinical social workers in New York and New Jersey as it relates to the intersection of ancestral wisdom and their profession. It addresses how Latine clinical social workers, who incorporate ancestral wisdom in their practice determine when, with which clients and with which methods to do so. This work advances current scholarship on how clinical social workers can combat racism and white supremacy. It highlights resistance practices that have been critical in keeping people indigenous to colonized lands alive and …

Who Is Invited To The National Family? A Brazilian Autoethnography Of Being A Woman Under The U.S. O-3 Visa, Bruna Lauermann

Dissertations, Theses, and Capstone Projects

This thesis lives in the borderlands between Brazil and the United States, during the nine years of my immigration to the United States. Using autoethnography, I analyze the O-3 visa as a tool that controls and alienates foreign women and devalues knowledge produced outside U.S. borders. This visa, for spouse or children of O-1 holders, which are people considered to have extraordinary abilities to work in the U.S. showcases the reasons why one is invited to be part of the national family and under what obligations and circumstances. A decision that is shaped far more by the interests of the …

Elite Manipulation Of Accountability Institutions: A Comparative Analysis Of Cicig And Maccih, Kevin E. Contreras

Dissertations, Theses, and Capstone Projects

Strong accountability institutions are expected to limit elite manipulation. Yet elites continue to manipulate them. This paper shows that strong accountability institutions are insufficient to prevent elite manipulation. A comparative analysis of Honduras (MACCIH) and Guatemala (CICIG) traces the relationship between institutional strength and elite manipulation. The findings indicate that this relationship is contingent on context. Preventing manipulation would require accountability institutions to sustain greater mobilization and institutional leverage than elites. Accountability institutions alone are insufficient to achieve this condition.

Exploring The Influence Of Ear-Level Devices On Adult Perceptions Across Professional, Social, And Educational Settings, Lucia R. Berry

Dissertations, Theses, and Capstone Projects

Background: The hearing aid market is continuously advancing to address the increasing prevalence of hearing loss and the barriers to obtaining hearing aids. The Food and Drug Administration (FDA) approved Apple AirPods Pro 2 devices to function as over-the-counter (OTC) hearing aids. This is an alternative option to manage hearing difficulties; however, it presents secondary complications related to headphone use and stigma.

Objective: Limited research is available regarding attitudes towards individuals wearing Apple AirPods Pro 2 as OTC hearing aids. This study intended to analyze if people’s pre-established perceptions of Apple AirPods shift once they learn they are being used …

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 …

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.

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? …

Reducing The Complexity Of The Experimental Design Attenuates Trait-Level Effects In Threat Safety Discrimination Learning, Justin M. Lazzarino

Dissertations, Theses, and Capstone Projects

Trait measures of negative emotionality have sometimes been shown to play a role in shaping threat learning, but findings are mixed. For example, Johnson et al (2023) showed that the inhibitory and prospective subscales of the Intolerance for Uncertainty Scale (IUS) were associated with diminished and enhanced threat-safety discrimination, respectively, during the acquisition phase of a Pavlovian fear conditioning task. This finding was subsequently replicated in an independent sample (Kinney-Petrucha, 2024, unpublished). However, these findings and other trait-level fear acquisition effects have not been consistently observed in the broader fear learning literature. Variation in the complexity of or uncertainty inherent …

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 …

The Three (3) Eras Of Compstat, Through Cultural Change. Lessons From The Past, Present And Future, Kevin Brown

Student Theses

Abstract

Using data and information from respondent surveys of current and former NYPD police executives, this study examines the cultural change, impact, and effectiveness of the NYPD’s CompStat system from the perspective of superior officers who have participated in it since its inception. CompStat was introduced in 1994 by NYPD, Police Commissioner, William Bratton.  Achieving cultural change in any police organization can be a monumental task, requiring CompStat’s transformational methods of data-driven accountability and four core principles that are aligned with organizational transformation evidence: timely intelligence, rapid deployment, effective tactics, and relentless follow-up.  This research explores how these principles have …

Socioeconomic Inequalities In Health-Related Quality Of Life During The Covid-19 Pandemic: A Six-Country Comparison Using The Eq-5d-5 L, Joëlle Eijkens, Joshua M. Bonsel, You-Shan Feng, M. F. Bas Janssen, Erica I. Lubetkin, Juanita A. Haagsma

Publications and Research

Purpose

Despite the growing attention to health inequalities, there is no global consensus on how to measure socio-economic status. This study examined inequalities in health-related quality of life (HRQoL) during the early phase of the COVID-19 pandemic across six countries—China, Italy, the Netherlands, Sweden, the United Kingdom (UK), and the United States (US)—using three SES indicators: education level, income, and work status.

Methods

Between April and June 2020, individuals aged 18–75 years old completed a web-based survey. HRQoL was measured using the EQ-5D-5L Level Sum Score (LSS), where higher scores indicate poorer health. Country-specific differences in LSS across SES groups …

Investigating Potential Bias In Public Acceptance Of Restorative Justice: The Influence Of Situational And Offender Characteristics, Kiara Haynes

Student Theses

Restorative Justice has been an emerging justice mechanism in the U.S. since the 1970s that advocates are working to expand more widely throughout the justice system. Due to victims and the broader community of the offender being an integral part of the Restorative Justice process, it is critical to consider the general public's support of this novel justice mechanism, as well as the influence that social biases among the public may have on the experience of defendants going through the system. The study conducted examined the effect that social biases toward an offender's personal characteristics have on attitudes and opinions …

The Security Of Llm-Generated Code, Christopher Brian Gonzalez Ayala

Student Theses

The rapid adoption of Large Language Models (LLMs) in software development has transformed coding practices by enabling automated code generation, completion, and optimization. Despite these advantages, concerns persist regarding the security and reliability of LLM-generated code. This study presents a comprehensive evaluation of both the functional correctness and security of code produced by three prominent LLMs as of early 2026. A total of 4,800 code snippets were generated using 100 security-focused programming prompts derived from the OWASP Top 10:2025, translated across eight natural languages and two phrasing styles (literal and natural developer-oriented prompts). To assess performance, a multi-stage experimental framework …

Forensic Analysis Of Temporary Tattoo Markers And Inks, Daniel J. G. Chasse Jr

Student Theses

As tattoos rise in popularity, some marker manufacturers have created temporary tattoo markers so that children and adults can experience tattoos without the permanence of a regular tattoo. These new products are marketed explicitly as ‘temporary tattoo markers’ and intended for direct application to the skin. This research aims to scientifically evaluate the inks from these temporary tattoo markers to elucidate their physical and chemical properties using wet chemistry, visual examination, ultraviolet-visible spectroscopy (UV/Vis), Fourier-transform infrared spectroscopy (FT-IR), attenuated total reflectance infrared spectroscopy (ATR-IR), thin layer chromatography (TLC), and diffuse reflectance infrared spectroscopy (DRIFTS) to analyze temporary tattoo markers and …

Adversarial Robustness Of Perceptual Hashing Systems: A Unified Security Evaluation Framework, Avijit Roy

Student Theses

Social network platforms, child safety organizations, and image provenance systems use perceptual hashing to identify known child sexual abuse material (CSAM), support content moderation and reverse image search, and verify image integrity. Perceptual hashing works by producing similar fingerprints for visually similar images, even after common transformations such as compression, resizing, or minor brightness changes. This useful similarity-preserving property also creates an adversarial attack surface, as attackers can use AI-assisted or conventional image manipulation techniques to move a hash across a matching threshold while maintaining visual similarity, often without access to specialized hardware.

The security failures produced by adversarial attacks …

The Comparative Chemical Analysis Of Colored Henna, Vani D. Bhagwandeen

Student Theses

Henna, a natural dye derived from Lawsonia inermis, is widely used for temporary body art, hair coloring, and cultural decorative practices such as Mehendi. Traditional henna produces a reddish-brown stain through lawsone, a naphthoquinone chromophore that binds to keratin in skin, hair, and nails (Badoni Semwal et al., 2014; de Groot, 2013; Kumar Singh et al., 2015). Commercial henna products have increasingly incorporated synthetic dyes, pigments, and glitter additives to produce a broader range of colors and effects (Blair et al., 2004; Manso et al., 2017; Blackledge & Jones, 2007). Despite their prevalence, limited forensic research has examined the …

Investigating The Detection Ability Of Presumptive Bloodstain Testing Through Concealment Obstacles, Skye E. Lehr

Student Theses

Bloodstain detection can provide valuable information on the ability of presumptive tests. When perpetrators seek to alter the scene of violent crimes to interfere with investigations or flee from justice, crime scene investigation becomes more complex. In this analysis, scenarios where bloodstain evidence is attempted to be removed by household cleaners and covered up by acrylic or oil-based paint, are tested using luminol and Kastle-Meyer direct testing. These bloodstains have been altered by bleach, dish soap or all-purpose cleaner and covered under multiple layers of acrylic or oil-based paint. Evidence is documented both photographically and visually to simulate crime scene …

A Qualitative And Quantitative Comparative Analysis Of Ballistic Bone Trauma From Frangible And Full Metal Jacket Projectiles, Hajar S. Hassan

Student Theses

Ballistic bone research is essential as 90% of homicides with the use of a firearm include injuries to bone. Forensic anthropologists use ballistic bone trauma to gather details and reconstruct an event, but ballistic bone trauma depends on many intrinsic and extrinsic factors. These factors include the type of bone, the type of firearm, and the type of ammunition. As new ammunition and firearms emerge, the literature on ballistic bone trauma remains limited. This novel study compares the bone trauma from the most common projectile, the full metal jacket, to a frangible projectile which is made to break upon impact. …

Temporal Integration In Music And Aesthetic Judgments: Assessing Musical Taste Through A Transformer-Based Approach, Sophia M. Senderak

Dissertations, Theses, and Capstone Projects

Music unfolds over time, requiring listeners to integrate information moment by moment to make aesthetic judgments. Although we know that music is likely processed on multiple timescales, it is not known which musical features contribute to short versus long timeframes. This study examined whether a computational measure of temporal integration could help explain aesthetic responses to music. Participants (N = 28) listened to 32 sixty-second clips of classical and electronic music, and continuously rated their enjoyment with a dial. After listening, they then gave an overall liking judgment for each clip. To quantify temporal integration, we derived an integration measure …

Identifying Helium Emission-Line Stars With The Condor Array Telescope, Julia Stewart

Dissertations, Theses, and Capstone Projects

Helium emission-line stars, including cataclysmic variables (CVs), AM Canum Venaticorum (AM CVn) binaries, symbiotic stars, and X-ray binaries, are tracers of compact object binary populations in the Milky Way, and may be viable progenitor systems of Type Ia supernovae. Their space densities are not well constrained - just over 100 AM CVn stars are known out of a Galactic population that may be closer to 100,000. Identifying such systems in large numbers requires wide-field, narrow-band photometric surveys capable of detecting faint emission-line sources across significant sky areas.

In this thesis, I present a narrow-band photometric search for helium emission-line stars …

Neural Correlates Of Recognition Memory And Metamemory In Breast Cancer Survivors: An Event-Related Potential Study, Dishari Zaman Azad

Dissertations, Theses, and Capstone Projects

Breast cancer survivors (BCS) often report noticeable cognitive difficulties despite showing limited impairment on standardized neuropsychological tests. Some have theorized that this is simply an insensitivity of standardized testing to subtle cognitive changes (test-insensitivity hypothesis), whereas others have suggested there are early neural changes that are detected by patients but precede detection by these tests (early signal hypothesis) or that when they achieve normal performance, it is through saliently effortful compensatory processes (compensation hypothesis). The present study tested these theories by assessing metamemory and recognition memory retrieval in BCS and non-cancer controls (NCC) using both behavioral and event-related potential (ERP) …

Exploring The Effect Of Babble Background Noise On Learning New Patterns In An Artificial Accent Of English In Monolingual And Bilingual Young Adults, Mariana Vasilita

Dissertations, Theses, and Capstone Projects

The current study examined how background noise affects the learning of novel phonetic and phonological patterns in speech. While prior research has shown that bilingual participants may learn new phonetic patterns more successfully than monolingual participants under quiet conditions, it remains unclear whether this advantage persists in more ecologically valid listening environments.

We investigated phonetic learning skills in monolingual English speakers (n = 13) and early bilingual speakers (n = 13). Participants were trained and tested on an artificial English accent presented in the presence of 12-talker babble noise (+10 dB SNR). A digit span task was also administered to …

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 …

A Simulation To Compare Models For A Longitudinal Ordinal Response With A Multilevel Cross-Classified Data Structure, Rachel S. Perlin

Dissertations, Theses, and Capstone Projects

This is a simulation study that compares four models for analyzing three-level longitudinal cross-classified data with an ordinal outcome, treatment effect and a category-specific effect. The models include the cumulative model, the sequential model, the adjacent category model, and a metric model. Data were generated for each of the first three models with 27,000 generated datasets each, totaling 81,000. The datasets vary along three continuous variables: the number of level-3 units, the ratio of treatment groups to control groups, and the treatment effect size. The outcome has four ordinal response categories. Each model had two predictor variables: treatment and time. …

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 …

Essays On The Economics Of Aging: Structural And Machine Learning Approaches, Alexander S. Kwon

Dissertations, Theses, and Capstone Projects

Population aging has made the study of older workers’ economic behavior increasingly important for understanding labor markets, retirement systems, and public policy. In many advanced economies, rising old-age dependency ratios have increased the need to understand labor-supply, retirement, and savings decisions later in life (OECD, 2025). In the United States, these issues are especially important because Social Security faces long-run financing pressure, with the Old-Age and Survivors Insurance Trust Fund projected to be depleted around 2033 (U.S. Social Security Administration, Office of the Chief Actuary, 2025). Longer life expectancy increases the expected length of retirement and raises the fiscal importance …

Buttressing Britain’S Financial Rise: Anglo-Dutch Brokers In Eighteenth-Century London, Jiwon Han

Dissertations, Theses, and Capstone Projects

Over the course of the eighteenth century, British financial markets developed remarkably and London established itself as the financial center of Europe, replacing Amsterdam. Scholarship on Britain’s financial developments in the eighteenth century has largely understood it as the result of British efforts and innovation. This dissertation complicates that understanding by investigating the Anglo-Dutch merchants in eighteenth-century London and their contributions to the development of British financial markets. In particular, their support was essential for the British government’s war finances, because Britain’s continuous wars against France demanded an immense amount of money and credit while its financial markets were still …
