Imagined Empires: Roman And Chinese Constructions Of One Another In Antiquity, Elizabeth S. Tsang

Dissertations, Theses, and Capstone Projects

This thesis examines how the Roman and Han Chinese empires conceptualized one another during the first centuries CE, despite never establishing sustained direct contact. It argues that mutual perceptions were shaped less by firsthand experience than by mediated reports, commodities, and the political interests of intermediaries. The study proceeds in four parts. The first explores how Roman authors employed the ethnonym Seres to frame China as a land of wonder, wealth, and alterity. The second analyzes the Chinese designation Da Qin, showing how it projected Han imperial ideals outward by casting Rome as a mirror-image polity. The third turns to …

Dónde Están: Searching For Desaparecidos Of The Argentine Dirty War, Paula Fleischer

Dissertations, Theses, and Capstone Projects

This project is a data physicalization textile representing the 30,000 'desaparecidos' from the Argentine Dirty War of late 1970s. The large quilt visualizes the official count of 9,000 missing persons in the shape of a headscarf worn by their mothers and grandmothers, while the overall dimensions of the quilt acknowledges 30,000 missing persons. The quilt and accompanying missing persons posters encourage the viewer to interact with the data, however the observed reluctance to engage influenced the direction of this discussion about the hegemonic disinclination to get involved when authority figures 'disappear' fellow residents of our communities.

Giving Voice To The Frames Of War: A Digital Humanities Framework For Evaluating War Crimes Databases, Leila Markosian

Dissertations, Theses, and Capstone Projects

Developments in digital technologies have complicated existing debates around the ethics of cataloging war crimes and human rights violations. Digital humanities methods of evaluating digital scholarship can help to construct a framework for evaluating war crimes databases, a process which requires a fine-tuned critical analysis aimed towards understanding the purpose of compiling the database, the platform or media template through which the database is presented, and the communicative potentials of the database. The following paper presents a survey of the existing literature on war crime databases and the politics of memory; a model of how war crimes database analyses may …

Ai-Powered Multi-Omics Integration For Predictive Modeling Of Genotype-Environment-Phenotype Relationships, You Wu

Dissertations, Theses, and Capstone Projects

This dissertation presents a series of machine learning frameworks for modeling genotype–environment–phenotype relationships through integrative predictive modeling of multi-omics data. The work addresses three major axes of biological complexity: modeling biological information transmission cross-levels from genes to proteins to phenotypes, predicting molecular features cross-scale from cells to tissues to organisms, and translating phenotypes cross-species from model systems to humans. Each proposed method also tackles key machine learning (ML) challenges in the biomedical domain, including data scarcity, domain shift, out-of-distribution (OOD) generalization, and hierarchical modeling. Specifically, this dissertation introduces five novel deep learning algorithms: MultiDCP predicts drug-induced transcriptomic and viability responses …

The Density Distribution Of The Material Around Betelgeuse, Iman Behbehani

Dissertations, Theses, and Capstone Projects

Betelgeuse is a red supergiant star visible in the constellation Orion. Its windy and highly convective surface results in a complicated mass loss pattern difficult to understand and replicate in simulations. The ejected mass can form a shell around the star we consider the circumstellar material (CSM). In this study, we use ALMA interferometric observations to find the structure of Betelgeuse's CSM, and connect to the mass loss mechanisms that could form it. We measure a bipolar circumstellar structure with a position angle of 42.3$\pm 7.0^\circ$. We observe asymmetries in the form of hot spots in the north east of …

Stolen Moments: Jazz And The Opportunity To Capture Hip Hop Fans, Fahiym Abdul-Wasi

Dissertations, Theses, and Capstone Projects

This thesis explores the intricate relationship between jazz and hip-hop, examining how these two influential genres intersect culturally and musically. Jazz, with its rich history and expressive improvisation, laid the groundwork for hip-hop, a genre that emerged as a powerful voice for Black Americans and other disenfranchised communities. The thesis highlights the impact of sampling, a fundamental technique in hip-hop that allows artists to repurpose jazz recordings and thereby preserve their legacy while infusing contemporary narratives. By analyzing key albums and the contributions of notable artists, this study underscores the potential for reintroducing jazz to new audiences through hip-hop. As …

In A Dark Wood Amid The Storm: Literary Representations Of Midlife In The Social And Political Turbulence Of A Kindred Era, Robert Mccreanor

Dissertations, Theses, and Capstone Projects

The apparent parallels between the social and political crises of the 19-teens’s to 1930’s and those of today is a source of popular fascination and commentary. Some have argued that much of our current anxieties about impending global doom harken back to the widespread doomsaying of exactly a century ago in relation to World War I, the 1918 Spanish Influenza and the rising authoritarianism of the 1930’s. Exploration of the midlife experience amid 21^st century political and social crises has been prolific and can also be seen to echo literary representations of this particular life stage from the seemingly …

“Justice, Justice Pursue”: Coworker Reactions To Religious Workplace Accommodations, Joshua A. Nagel

Dissertations, Theses, and Capstone Projects

This study examines coworker reactions to religious accommodations in the workplace, a growing necessity as religious diversity increases, and recent legislation strengthens protections for religious observances. Religious accommodations can provoke perceptions of differential treatment, impacting coworker morale, cooperation, and organizational cohesion. While extensive research exists on disability accommodations, religious accommodations differ fundamentally as they often relate to moral beliefs and are viewed variably in terms of necessity and controllability. Drawing on organizational justice theories, this dissertation applies and modifies Colella’s (2001) and Colella et al.’s (2004) models for coworker perceptions of distributive and procedural fairness of disability accommodations to the …

The Spaces Between: A Phenomenological Exploration Of Classical Music Performance Practice, Fifi Zhang

Dissertations, Theses, and Capstone Projects

In his theory of duration, the philosopher Henri Bergson (1859-1941) asserts that the present moment is “both a perception of the immediate past and a determination of the immediate future…a joint system of sensations and movements.” In an ideal musical performance, this sensori-motor apparatus guides every one of the performer’s decisions on stage, resulting in an aural experience that is spontaneous, visceral, and deeply personal. In practice, much of today’s classical music performance culture, which relies heavily on visual notation and prioritizes fidelity to the composer’s intent, is antithetical to fundamental artistic values such as creativity, individual self-expression, and direct …

Alerted And Anxious? The Effects Of Mobile Crime Alerts On Perceptions Of Personal And Public Safety, Amanda C. Benjamin

Dissertations, Theses, and Capstone Projects

Mobile crime alert platforms promise to enhance personal and public safety by delivering frequent notifications about nearby dangers—claims that, until now, have not been experimentally tested. For-profit applications like Citizen deliver real-time, geo-targeted push notifications about nearby crime incidents to over 9 million users, often operating outside the bounds of institutional oversight. Although marketed as tools to enhance awareness and protection, these platforms may simultaneously empower users through information while also potentially amplifying anxiety, heightening threat perceptions, and eroding trust in community. Despite their increasing prominence and integration into public safety communications, the psychological and behavioral impacts of mobile crime …

The Question Of Money: State, Protest, And Informal Currencies In The Wake Of Greece’S Economic Crisis, Helen Panagiotopoulos

Dissertations, Theses, and Capstone Projects

Monetary unions are designed to foster political, social, and economic integration among member states by enabling the free movement of people, goods, services, and capital. Yet when a member nation faces economic crisis, citizens may respond by creating monetary systems of their own. This research asks whether such practices are simply demonstrations of human resiliency and adaptability, or whether they also challenge the very idea of a shared market and currency that do not align with national identity. Greece offers a crucial case for this inquiry. Following the 2008 debt crisis, austerity measures led to economic depression, mass unemployment, and …

Nonlinear Diffusion, Hydrodynamic Cascades And Jamming In Kinetically Constrained Systems: Insights From Lattice Gas Models, Abhishek Raj

Dissertations, Theses, and Capstone Projects

This dissertation investigates non-linear diffusion processes and emergent dynamical phenomena in kinetically constrained lattice gases. Two central models are considered: a one-dimensional lattice gas exhibiting a diffusion cascade triggered by hydrodynamic nonlinearities and a triangular ladder exclusion model that undergoes a jamming transition. The former demonstrates stretched exponential decay consistent with non-perturbative long-time tails, while the latter illustrates how classical-quantum mappings yield insight into glassy dynamics and mobility constraints. Through a combination of numerical simulations, analytical perturbation theory, and mean-field approximations, the work uncovers mechanisms underlying anomalous transport, jamming transitions, and the breakdown of perturbative hydrodynamics.

Choreographies Of Care: Disability And Relationality In Performance, Kiera Bono

Dissertations, Theses, and Capstone Projects

My dissertation explores enactments of what I am calling “choreographies of care” in interdisciplinary performance practices in the 21^st century. Working across disability studies, race and ethnicity studies, queer theory, and performance studies, I investigate the ways in which chronically ill and disabled artists have generated multisensorial movement, sound, and performance works that resist normative understandings of time, space, bodies, and interactions between bodies. Focusing mostly on performances and events that I have attended in New York City or virtually over the past decade, my project engages directly with disability arts communities in which I have been deeply embedded …

Nonlinear Optics Through Femtosecond Light-Matter Interactions, Shah Faisal B. Mazhar

Dissertations, Theses, and Capstone Projects

This dissertation offers experimental and theoretical insights into nonlinear light-matter interactions induced by intense femtosecond (fs) laser pulses. It investigates key phenomena, including stimulated Raman scattering (SRS) from phonon and magnon quasiparticles, supercontinuum (SC) generation via self-phase modulation (SPM), conical emission (CE) arising from four-wave mixing (4WM), and modulation instability (MI) driven by cross-phase modulation (XPM) between SRS and SC processes. These effects are studied in diverse media using state-of-the-art femtosecond lasers.

The interplay among SRS, SC, 4WM, and MI is examined to probe vibrational modes and temperature-dependent magnetic excitations in condensed-matter systems. Experiments are conducted on anisotropic uniaxial calcite …

Teaching And Technology: "You Can't Just Do The Same Thing Online", Sakina Laksimi

Dissertations, Theses, and Capstone Projects

This dissertation examines how faculty at the City University of New York navigated the abrupt transition to online teaching during the COVID-19 pandemic, revealing how pedagogy is shaped by technological, institutional, and social conditions. Drawing on twenty-two interviews with twelve faculty across eight disciplines, I use a grounded theory approach to analyze how instructors adapted courses, reimagined assessment, and sustained connection with students amid crisis. Three overlapping pedagogical orientations emerged: improvisational, relational, and design-based teaching. These approaches highlight how faculty balanced responsiveness, care, and intentional course design in environments mediated by digital platforms and marked by inequity. The study situates …

Performance Practice As Compositional Style: Wet Ink’S Collaborative Work, Carrie Frey

Dissertations, Theses, and Capstone Projects

In its twenty-five years in New York City’s new music scene, Wet Ink Ensemble has established a distinctive approach in which members blend the roles of performer, composer, and improviser. This dissertation investigates how the ensemble’s beginnings at the nexus of the experimental rock and avant-garde music scenes prepared it for a turn towards collaborative composition and improvisation. After defining essential elements of the ensemble’s performance practice, I analyze Eric Wubbels’ Auditory Scene Analysis (I) and Sam Pluta’s Lines on Black—compositions that exemplify opposing poles of notational specificity. I then trace the defined elements through two “Performance Practice” works, …

The Effect Of Tbi On Working Memory And Anxiety In Rats, Mariola Sobolewska

Dissertations, Theses, and Capstone Projects

Traumatic Brain Injury (TBI) is a significant public health concern, often leading to cognitive and emotional impairments. This study examined the effects of TBI on working memory and anxiety-like behavior in young male Sprague-Dawley rats using the Radial Arm Maze (RAM) and Elevated Plus Maze (EPM), which are behavioral assessments. The RAM tests spatial working memory by evaluating the animal’s ability to remember and efficiently navigate multiple arms to retrieve rewards. The EPM assesses anxiety-like behavior based on the animal’s preference for open versus closed arms. The study utilized young male Sprague-Dawley rats, a well-established rodent model known for its …

The Architecture Of Exclusion: Disability, Race, And The History Of New York City’S 600 Schools, Francine Almash

Dissertations, Theses, and Capstone Projects

This dissertation investigates the largely erased history of New York City’s 600 schools—segregated public schools created to house students labeled as emotionally disturbed or socially maladjusted. These institutions, operating throughout the mid-20th century, disproportionately served Black and Puerto Rican youth, many of whom were placed in these schools under vague behavioral criteria and with little to no pathway for return to general education settings.

Combining archival research, longitudinal policy analysis, historical media review, and critical race and disability studies frameworks—including DisCrit (Disability Critical Race Theory)—this project situates the 600 schools at the intersection of institutional racism and ableism. It argues …

Text-Based Propaganda Detection, Vivek Sharma

Dissertations, Theses, and Capstone Projects

In the digital age, the swift consumption of news and the widespread dissemination of propaganda significantly threaten democratic principles and informed decision-making. News organizations, often aligned politically, tailor their content to appeal to specific audiences, thereby perpetuating biases. Despite advancements in detecting propaganda through various computational techniques, including Large Language Models(LLM) and BERT-based approaches, significant challenges persist concerning data availability and the effectiveness of detection tools. This thesis explores the landscape of text-based propaganda and reviews related research in textual analysis. It introduces a novel method for collecting a social-media based dataset, which includes analysis of journalists' tweets to discern …

Double Exposure: Motherhood And Filmmaking, Eddy Berzak

Dissertations, Theses, and Capstone Projects

This capstone project explores the intersection of motherhood and filmmaking through a reflexive documentary that examines how women directors have historically navigated the tensions between creative careers and raising children. Drawing on feminist film theory and autoethnographic methods, the fourteen-minute video essay analyzes three pioneering autobiographical documentaries from the 1970s—Joyce at 34 (1973), Nana, Mom and Me (1974), and Women Are Naturally Creative: Agnès Varda (1977)—alongside original footage documenting my own experience as a mother with deferred filmmaking aspirations. The project employs reflexive documentary techniques to weave together film analysis and personal narrative, investigating the central question: why didn't I …

Online Resources For Oral Communication Courses, Sean P. Palmer

Dissertations, Theses, and Capstone Projects

Online resources focusing on oral communication skills are lacking, even as online education itself expands. While I was aware of this lack, I didn’t realize its severity until LaGuardia Community College went fully remote during the 2020 global pandemic, and I was looking for online tutoring aids for oral communication. Furthermore, the information presented online is frequently unsuitable for the purposes of online pedagogy due to its specialized and jargony mode of presentation. Also, many existing assignments involving oral communication assume public speaking as the default model, despite the growing importance of emergent digital modes of oral performance, like podcasting …

Between The Buffer And The Black Box: Ed(1), Invisible Text, And Delegation In Word Processing, Kai Prenger

Dissertations, Theses, and Capstone Projects

This thesis provides a media archaeological and theoretical examination of ed(1), the Unix line editor developed by Ken Thompson at Bell Labs in 1969, arguing that its approach to "invisible text" processing established lasting patterns of human-computer collaboration that persist in contemporary digital systems. Through historical research, technical analysis, and critical interpretation, this study demonstrates how ed(1) embodied a particular epistemology of text processing that appears alien in a contemporary context, but proves insightful in the age of generative text creation.

ed(1) emerged from the unique convergence of Bell Labs' collaborative research culture, severe hardware constraints of early Unix systems, …

Socioeconomic Stasis And Racial Immobility In The United States: How Does American Political Polarization Contribute To African American Poverty?, Carmel Agnant

Dissertations, Theses, and Capstone Projects

African Americans in the United States presently exist in a poverty-stasis, a perpetual social and economic underclass positioning despite a constantly evolving American economy, society, and bodies of legislations due to political polarization. This follows a lengthy history of racial immobility (preventing a racial group from economic mobility) and stagnation since America’s era of sectional polarization over slavery. African Americans lack access to build wealth and have always struggled with societal exclusion. Legislation created and enacted that would support them politically, legally, socially, and/or economically are consistently met with legislative gridlock or countervailing measures to reverse and nullify advancements in …

Detecting Sonic Hedgehog Expression In The Adult Mouse Brain Using A Gene Expression Tracer, Kendra Stephens-Jones

Dissertations, Theses, and Capstone Projects

Sonic Hedgehog (Shh) is best known for its role in development, yet evidence supports Shh signaling plays a functional role in the adult brain. Previous work demonstrated that Shh is expressed by dopamine (DA) neurons in the ventral midbrain and that loss of Shh from these neurons leads to late-onset motor and structural abnormalities resembling Parkinson’s disease. However, the extent of Shh expression and its connectivity to the striatum in the adult mouse brain remain unclear due to the lack of reliable antibodies for Shh detection. To address this gap, the present study employed Shh ^L/L and DAT-Cre^+/- mice …

Re-Envisioning Digital Agency: From Representationalism To Interpretant-Driven Epistemology, Michael C. Lee

Dissertations, Theses, and Capstone Projects

This thesis examines the epistemological and ethical foundations of digital technologies, particularly code and algorithmic systems, by considering their entanglement with representationalism. Arguing that code now functions as a dominant social agent and epistemic subject, through the concept of the Code’s-eye view, I explore how automated datafication reduces human experience to quantifiable inputs, reinforcing epistemic closure and social fragmentation. Drawing on pragmatist philosophy, including Peirce’s semiotics, Dewey’s democratic ethics, and Rorty’s conversational inquiry, I propose an interpretant-driven epistemology grounded in communal inquiry and interpretive openness. This alternative framework resists the binary logic of algorithmic rationality by emphasizing conflict and the …

Prerogative In Common: On The Emancipatory Potential Of Radical Mutuality Amid Sovereign Decisionism, Matthew Builes

Dissertations, Theses, and Capstone Projects

In times of crisis, liberal democracies resort to authoritarian measures that undermine core democratic values. Dominant thought in the study of emergency-era law and politics appeal to a dichotomy of normal and exceptional times, to critique or justify the turn to sovereign decisionism. While this strategy seems clear-cut, the persistence of exceptional spaces and the crises that supposedly generate them challenge existing frameworks by blurring the line between norm and exception. This project explores the prospect of radical mutual aid, as a transformative response to the enduring crisis of modernity.

Flotsam And Jetsam: The Role Of Mlb Integration In The Wreckage Of The Negro Leagues, Nastasia Pollas

Dissertations, Theses, and Capstone Projects

“We are the ship, all else the sea.” Adapted from a Frederick Douglass speech, this quote by Rube Foster became the slogan of the Negro Leagues, illustrating the resolve and determination to prosper alone during a time of segregation. Setting aside long-standing rivalry and strife, Black baseball teams united under a shared vision of forming the first professional Black baseball league.

This paper examines how Giddens' structuration theory, connecting social structures with individual actions, can explain both the development and success of the league under segregation and its eventual demise during integration.

Effect Of Equation Of State On The Formation Of Binary Black Holes In Active Galactic Nucleus Disks, Theodore Edwards

Dissertations, Theses, and Capstone Projects

Active galactic nucleus disks have been proposed as a possibly dominant location of the mergers of binary black holes detected by gravitational wave observatories. The nonlinear interactions between stellar mass black holes and disk gas determine when binaries will form from single objects on nearby orbits. Prior work has used smoothed particle hydrodynamics models in an isothermal disk to study this problem. However, the local equation of state near the midplane of an optically thick accretion disk is adiabatic rather than isothermal, even if the radiative equilibrium temperature is azimuthally isothermal. Therefore, we investigate the use of an adiabatic equation …

Developments In The Lithographic Engineering Of Bi2sr2cacu2o8+Delta Mesa Terahertz-Emitting Devices, Sarah Elghazoly

Dissertations, Theses, and Capstone Projects

Devices microfabricated from the high-temperature superconducting cuprate Bi₂Sr₂CaCu₂O_8+𝛿 (Bi-2212) are a promising source of coherent terahertz radiation within the ’terahertz gap’ (0.3- 1.5 THz). A current-biased mesa patterned into the surface of a single crystal will produce electromagnetic radiation in the terahertz regime due to the naturally occurring Josephson junctions formed by the stacks of superconducting cuprate oxide planes in the material separated by insulating BiO and SrO barrier layers. Previous research has shown that by fabricating these mesas such that the geometry supports resonant cavity Fabry-Perot modes, the junctions within the mesa …

Processing Of Diphthongs By Turkish English Bilinguals: An Erp Study, Ecem Kopuz

Dissertations, Theses, and Capstone Projects

This study examines how native phonological experience influences the brain’s response to speech sounds in Turkish-English late bilinguals and English monolinguals. We asked whether neural responses reflecting encoding of auditory information would be sensitive to language specific experience. Using event-related potentials (ERPs), and specifically, the Acoustic Change Complex (ACC) we measured neural responses to four stimuli, /u/, /ua/, /iu/, and /ia/, where vowel quality changes for three of these. A change from /u/ to /a/ or /i/ to /a/ within a syllable (as in [ua] and [ia]) represents a clear vowel quality shift. All participants were expected to show sensitivity …
