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 …

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 …

Riding Two Cities: A Data Visualization Capstone Comparing Nyc's Bmt Subway And Tokyo's Yamanote Line, Andreina R. Abreu

Dissertations, Theses, and Capstone Projects

Every weekday, millions of people trust two radically different urban rail systems to get them where they need to go. New York City’s Brooklyn-Manhattan Transit (BMT) group threads through the boroughs in a branching web of eight lines. Tokyo’s Yamanote Line runs as a single, closed loop around the capital’s core. Both systems move enormous volumes of people through dense, high-demand environments, but they do it in fundamentally different ways, and they share very different amounts of information about how they’re doing it. According to federal reporting, MTA New York City Transit served over 1.1 billion unlinked passenger trips in …

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 …

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 …

Essays On Behavioral Aspects Of Retail Operations, Ceren Gultekin

Dissertations, Theses, and Capstone Projects

This dissertation combines a structured literature review on availability signaling in retail with two analytical chapters on inventory disclosure. The literature review incorporates the design and key insights of a systematic review and identifies directions for future research. Inventory disclosure is a form of availability signaling through which retailers strategically communicate stock levels to influence consumer buy-now-or-wait decisions. To mitigate strategic purchase deferrals, retailers may share low stock to create urgency or mask high stock to prevent consumers from relying on abundance. Despite its importance for profitability, academic findings and industry practices vary widely, ranging from consistent sharing to consistent …

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 …

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 …

Considering Numerical Relativity For Upgrades In Mcfacts Merger Dynamics, Shawn K. Ray

Dissertations, Theses, and Capstone Projects

Binary black hole mergers (BBH), some likely originating from active galactic nuclei (AGN), are observed by ground-based detectors such as LIGO-Virgo-KAGRA (LVK) and will be detected by future space-based detectors such as the Laser Interferometer Space Antenna (LISA) and the Laser Interferometer Lunar Antenna (LILA). The dynamics of AGN may be responsible for a significant fraction of BBH mergers soon to be observed by LISA and LILA, yet the dynamics of BBH mergers within AGN disks remains ambiguous despite their appearance in gravitational wave observations. Monte carlo For AGN Channel Testing and Simulation (McFACTS) is an open-source software used to …

Managing Multi-Channel Service Operations, Omer Berk Olmez

Dissertations, Theses, and Capstone Projects

In today’s evolving service landscape, the growth of virtual channels alongside traditional in-person services is changing how providers interact with customers and how services are delivered. This dissertation studies how service systems should be designed and managed when customers can choose between virtual and in-person channels through three connected perspectives: customer behavior, work design, and public policy. The first study examines booking-window design in a pooled multi-channel appointment system using appointment-level data from an undergraduate advising office, a queueing model, and a digital twin. It shows that booking windows shape the offered set and the flow of demand across channels, …

Pedagogy Of Care: Exploring Climate Justice Frameworks In Cuny Undergraduate Courses, Ismerlyn Gonzalez

Dissertations, Theses, and Capstone Projects

Climate justice centers the human rights of communities most impacted by the climate crisis rather than solely focusing on the scientific aspects of environmental challenges and disasters. Higher education institutions play a key role in advancing climate justice education, but research shows that frameworks are not consistently defined across institutions. The IRB-approved study that produced the findings in this capstone sought to explore how climate justice frameworks are implemented at the CUNY undergraduate level and learn more about the instructors delivering these courses. From February to April 2026, instructors from different CUNY undergraduate campuses were surveyed, interviewed, and asked to …

Investigating Individual And Group Level Mediators Of Fear Acquisition, Rachel S. Lese

Dissertations, Theses, and Capstone Projects

The ability to discriminate between cues predictive of threat vs. safety (fear acquisition) and subsequently update fear responding when contingencies change (fear extinction) is crucial to survival for all organisms. While these processes have been the subject of intense experimental scrutiny for several decades, most human fear learning studies have focused primarily on extinction learning and fear recovery processes, with less focus on fear acquisition itself. Indeed, researchers typically aim to minimize variability during fear acquisition in order to rule out differences in extinction being driven by variability during the initial learning phase. Thus, experimental protocols are often optimized to …

The Other Sodomites: A History Of Racial Queerness, Paris Shih

Dissertations, Theses, and Capstone Projects

The Other Sodomites traces the "racial logic of sodomy" from the medieval to modern periods. Reading across a wide range of literary and cultural texts, including medieval tales, theological treatises, travel narratives, stage plays, topographical poems, and prose fiction, the current study explores the structural relationship between discourses of sodomy and pivotal moments of racialization in western history, from the Judaization of sodomy in the Middle Ages, through its Islamization and Catholicization during the global Renaissance, to the continentalization and orientalization of sodomy in the nineteenth century. Despite the shifting zones of sodomitic significance, there existed a persistent racial logic. …

Conga Santiaguera: A Century Of Innovation And Competition, Nick Herman

Dissertations, Theses, and Capstone Projects

Santiago de Cuba is home to the island’s biggest, oldest, and most famous carnival.  Any local resident will confirm that “sin conga no hay carnaval (without conga there is no carnival).” In Santiago, conga refers to a vibrant street procession, the music that drives it, and the ensemble that makes the music.  Conga Santiaguera: A Century of Innovation and Competition presents a musical history of the conga from roughly 1910 to 2010.  This project, https://cuny.manifoldapp.org/projects/conga employs an eBook, musical analysis, oral histories, and audiovisual media to show how the conga has been constantly reinvigorated by innovation, competition, and Afro-Diasporic …

An Ecological Approach To School Climate, Safety, And Space: Accounts From Educators, Architects, And Guidelines, Mahnaz Izadi

Dissertations, Theses, and Capstone Projects

This dissertation explores how the spatial and social contexts of schools interact to influence how school safety and climate are perceived and enacted. Using ecological psychology theories, I examined the perspectives of teachers, counselors, and architects, school stakeholders involved in school planning and operation at different times, with varying levels of control and involvement in the daily life of schools. The study investigates how these stakeholders think about school climate and safety, the strategies they employ to improve it, and the challenges they face in doing so.

This qualitative study employs semi-structured interviews with 11 teachers and 4 counselors from …

Theatrical Agency In The Constitution Of Logical Space, Esther Marveta Neff

Dissertations, Theses, and Capstone Projects

This dissertation takes advantage of our current moment of collapse and shifting episteme to move from resistance and critique into modes of position, prefiguration, and praxiocentricism, giving not only a critique of the colonial-modern logical space of Theatrum Mundi, but also aiming to configure the thetic consciousness that grounds “theatrical agency” in the logic of cognitive and social epistemological modelling.  In what ways do we “build our own worlds”? What does “theatricality” tell us about human agency, especially in the domain of “theoretical attitudes,” and “consciousness”? In what ways, and to what extent, are we responsible for constituting …

Immunomodulatory And Signaling Molecules From Plant-Associated Bacteria: Toll-Like Receptor 4 Agonist Adjuvants And Diketopiperazine-Mediated Communication, Marian Romaine

Dissertations, Theses, and Capstone Projects

Medicinal plants and their associated microbiomes constitute a rich source of bioactive natural products with applications in immunotherapy and microbial ecology. Herbal formulations have long been valued for safe immune enhancement, while bacterial signaling molecules govern community behaviors critical to pathogenesis, symbiosis, and environmental processes. Bacterial lipopolysaccharides (LPS) from plant-associated Gram-negative bacteria have emerged as potent TLR4 agonists, yet their endotoxic potential limits direct use, and diketopiperazines (DKPs) serve as versatile quorum-sensing mediators capable of modulating biofilms in mixed microbial systems.

The work in this thesis comprises two independent but complementary research strands. The first strand pursued the engineering of …

Cooling Deserts For Renters: Heat Equity Inside The Nyc Housing System, Tahreem Ashraf

Dissertations, Theses, and Capstone Projects

This study introduces the Cooling Desert Index (CDI), a composite spatial measure designed to identify census tracts in New York City where extreme heat vulnerability and structural barriers to adaptive cooling converge. Drawing on five publicly available datasets and a seven phase statistical pipeline, the CDI scores all 2,231 NYC census tracts on a continuous 0 to 100 scale by integrating heat exposure, severe rent burden, household income, racial composition, language access, disability status, and housing crowding. The analysis identifies 557 cooling deserts, defined as tracts where environmental heat risk is high and financial constraints make effective cooling structurally inaccessible, …

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 …

Three Degrees Of Representation: How Genai Filters, Retrieves, And Remixes Lesbian Film Data, Maria G. Baker

This project investigates how generative AI systems assemble, filter, and represent Lesbian film data. Through auditing GenAI outputs across multiple dimensions (text, images, metadata), 3°R explores what gets included, excluded, and transformed in the process.

—

Three Degrees of Representation is a public website (https://mgb513.github.io/lesfilm-meets-AI/) featuring an investigation of AI-generated images and texts in response to Lesbian film data. Filtering simple prompts based on Lesbian film titles through the algorithms of AI image and text generators makes visible how these systems digest and remix existing (training) data, and how aspects of Lesbian representation are either amplified or suppressed …

Exploring Minor Feelings: Asian And Asian American’S Racialized Emotions, Identity, And Mental Health Amidst Covid-19, Kristina Mirasol Arevalo

Dissertations, Theses, and Capstone Projects

The COVID-19 pandemic highlighted the central role of racialized emotions in shaping how Asians/Asian Americans (A/AA) experience, interpret, and respond to racism, yet these emotional processes remain underexamined in psychological research. Rather than treating emotions as outcomes of discrimination, this dissertation conceptualizes racialized emotions as dynamic processes through which structural racism is experienced, interpreted, and embodied in everyday life. This framework positions racialized emotions as a key mechanism linking racialized social contexts to identity development and mental health. Across three studies using qualitative and quantitative methods, I examine how racialized emotions shape racial meaning-making, ethnic-racial identity, and psychological well-being among …

The Desire Of Strict Souls: The Poetry, Criticism, And Letters Of Paul Valéry And Wallace Stevens, Michael Healy

Dissertations, Theses, and Capstone Projects

This dissertation compares the poetic, critical, and epistolary oeuvres of Paul Valéry and Wallace Stevens and the influence of the former on the latter. Valéry famously advocated for the pursuit of “poésie pure” (“pure poetry”) and influenced Stevens especially in this way, though both of them concluded it was not achievable. I establish an approximation of a critical framework based on the work of the following critics and scholars: Wendy Lesser, Wendy Steiner, Anthony Cuda, Michael Clune, Paul Bové, and Liesl Olson. Harold Bloom’s passionate advocacy and deep, sustained engagement with Stevens and his work strongly influenced my choice to …

Beyond The Veil Of Modernity: René Guénon, Prophet Of The Metapolitical Imaginary, Frederic Colier

Dissertations, Theses, and Capstone Projects

Heralded by some as one of the greatest intellectuals of the 20th century, French metaphysician René Guénon (1886-1951) is also the controversial father of Primordial Tradition, a metaphysics designed to remedy the decline of Western civilization. Guénon viewed the West in the grip of a prolonged cycle of degeneration. He sought to implement a pseudo-authoritarian spiritual reset that required a total rejection of its Western intellectual heritage and an embrace of Eastern doctrines.

Focusing on his landmark book The Crisis of the Modern World (1927), the dissertation examines how Guénon implemented his controversial reset. After outlining the religious, cultural, and …

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 …

Profiling Nucleolin Phosphorylation During Dna Damage Response And Cell Cycle Arrest, Hanjun Jeon

Dissertations, Theses, and Capstone Projects

This dissertation examines site-specific and global phosphorylation dynamics of nucleolin (NCL) in response to DNA damage and cell-cycle perturbations. By combining phospho-specific immunoblotting with Phos-tag SDS-PAGE analysis, distinct phosphorylation patterns were identified across experimental conditions. The results define reproducible, condition-dependent phosphorylation states of NCL and provide a framework for studying its regulation under cellular stress.
