Moving The Needle: The Policy Of Change On Syringe Access, New York City And State, 1988–2023, Joyce Rivera

Dissertations, Theses, and Capstone Projects

By the mid-1980s, the HIV/AIDS epidemic breached a longstanding consensus between the political class and its bureaucratic alliances that had relied for decades on attitudes and orientations that championed punitive prohibition toward drugs as a bedrock principle of policy making. This ‘focusing event’ created an opening for HIV/AIDS activists to build a movement that offered an alternative, a more effective and just approach to how government policies and practices can manage illegal drugs and the persons who use drugs.

The dissertation uses several theoretical and methodological tools to address the central research objective that highlights the critical role played by …

Modeling Depressive Patterns In Italian Discourse: Insights From Natural Language Processing, Annapia Borraccino

Dissertations, Theses, and Capstone Projects

Depression does not always speak in obvious ways. It often hides in silence, in brief pauses, and in the quiet texture of language. While the prosodic and linguistic characteristics of depression have been extensively studied in English and other languages, they remain underexplored in Italian, with this being a first focused analysis. This study investigates how depression manifests in the speech of Italian speakers, using transcriptions from a clinical corpus. Drawing on emotional, structural, and cognitive-linguistic features, including first person verb use, sentence complexity, verb tense, and negation, the study evaluates how these markers differ between individuals with and without …

Exploring The Enstatite Chondrites: Modal Abundances, Metamorphic History, And Volatile Challenges, Mabel Gray

Dissertations, Theses, and Capstone Projects

This thesis investigates the formation conditions, thermal histories, and volatile inventories of enstatite chondrites (ECs). A diverse set of ECs is analyzed to capture the broad variability within this meteorite class. Chapter 1 presents a comparative analysis of mineral abundances using automated point counting, X-ray diffraction analysis, and XMapTools-based phase mapping. The results reveal significant variations in silicate and sulfide abundances across EC groups, challenging the conventional binary classification and suggesting distinct formation conditions. Chapter 2 explores the thermal histories of two highly equilibrated EH chondrites, proposing a novel formation mechanism on the parent asteroid: contact metamorphism driven by an …

This qualitative study examines the experiences of Black males in New York City Men Teach (NYCMT), a diversity initiative designed to increase the representation of Black male educators. Despite efforts, Black men remain underrepresented in education. Drawing from narrative-inquiry and guided by Critical Race theory and the Radical Care framework, this research explores how participants experience NYCMT and what their stories reveal about the effectiveness of diversity initiatives. Data from Semi-structured interviews were analyzed using thematic analysis, revealing five key themes: community, financial benefits, mentoring, professional development, and challenges. Findings show that while NYCMT offers critical emotional, financial, and structural …

Hope By A Thousand Cuts: Fashion Ethics From Cutting Fabric To Cutting A Fashion Film, Sarah G. Porterfield

Dissertations, Theses, and Capstone Projects

I conducted an experiment during which I learned to sew, created a clothing collection, and wore nothing but my collection for a month. Additionally, I documented my collection and the process in a fashion film. The goal of my experiment was to investigate fashion ethics. To gain a greater understanding of the underlying theories that fashion materializes and to grasp their ethical implications better, I studied the texts of fashion theorists such as Marx, Barthes, Derrida, Deleuze and Guattari, Butler, Benjamin, and Merleau-Ponty throughout my experiment. Therefore, I gained insight into many aspects of fashion ethics, from the beginning stages …

Seeing And Sanctioning Structural Unfairness, Grace Flores-Robles

Dissertations, Theses, and Capstone Projects

People tend to explain wrongdoing as the result of a bad actor or bad system. In five studies (including U.S. online convenience samples, and one U.S. census-matched sample), we tested whether the way people understand unfairness affects how they sanction it. In Study 1 (N = 370), people interpreted unfair offers in an economic game mostly as the result of a bad actor (vs. unfair rules), which predicted costly punishment of individuals (vs. changing unfair rules). In Studies 2 (N = 500) and 3, (N = 470, census-matched on age, gender, and ethnicity in the U.S), we …

Menstrual Math: The Price Of Bleeding, Gabrielle Langston

Dissertations, Theses, and Capstone Projects

This project examines the landscape of menstrual equity in the United States through a data storytelling lens, focusing on state-level policies regarding taxation and access to menstrual products. The analysis explores which states impose sales tax on menstrual products, if state schools provide free menstrual products, and which states ensure access for incarcerated individuals using publicly available datasets from advocacy groups. Additionally, there is an investigation into potential correlations between the gender wage gap and states that tax menstrual products, shedding light on economic and policy disparities.

Through its data visualizations, this project aims to provide a clear, although not …

Computability Theoretic Aspects Of Profinite Groups And Models Of Presburger Arithmetic, Jason Block

Dissertations, Theses, and Capstone Projects

Profinite groups, which are exactly the Galois groups, are all either finite or uncountable. However, all second countable profinite groups can be presented as the set of paths through a countable tree. We use these tree presentations to find upper bounds on the complexity of the existential theories of profinite groups, as well as to prove sharpness for these bounds. These complexity results enable us to distinguish the class of profinite groups that are isomorphic to a direct product of finite groups, for which we find an upper bound on the complexity of the entire first order theory. Additionally, given …

How Argentina Won The 2022 Fifa Men's World Cup: A Data Story, Aniruddha Parthasarathy

Dissertations, Theses, and Capstone Projects

This project analyzes Argentina’s 2022 FIFA Men’s World Cup win using open-source football (soccer) data. The project evaluates the team’s performance at a micro-level across three domains: without possessing the ball, possessing the ball and the team’s in-game management tactics. A statistical framework, i.e., multiple linear regression modeling, was used to identify the five key defensive actions influencing the Argentinian team’s intensity of pressure applied, and visualized by heatmaps and time-segmented plots. More specifically, an Expected Threat (xT) analysis quantified the threat or danger from passes and progressive carries (moving the ball at least 10 meters), revealing that Lionel Messi’s …

Beyond Country: Southern Language And Identity In North Mississippi, Meredith Hilliard

Dissertations, Theses, and Capstone Projects

This dissertation is about the language of the US South and the identities of the people who inhabit it. Its purpose is twofold: (1) to explain, on micro- and macro-levels, the processes of enregisterment (Agha 2003) of Southern US English, drawing conclusions about the phenomenon of enregisterment more generally; and (2) to articulate the relationship of Southern redneck identity to this process of enregisterment. It uses a mixed-methods approach that relies primarily on a Critical Discourse Analysis (CDA) methodology, adopting a stancetaking approach (Du Bois 2007) and an enregisterment approach to language and identity, with some quantitative elements, to analyze …

Localization Of Music In Perceived Motion In Cochlear Implant Users, Madeleine Beyer

Dissertations, Theses, and Capstone Projects

Spatial perception contributes to music perception and enjoyment, yet it remains understudied in cochlear implant (CI) users. Spatial effects in music are often achieved through panning, a tool which redistributes an audio signal level between or among several outputs, creating a perceived sound localization. CI users typically perform worse than normal hearing (NH) listeners on tasks of horizontal localization and music perception when manipulating the actual location of the sound. However, despite the common use of panning in daily use and consumption of music, no previous studies were conducted to examine how panning impacts the listening experience for CI users. …

Streaming Instabilities In Class 0/I Disks, Shirin Gul Zaidi

Dissertations, Theses, and Capstone Projects

While it is clear that planets form in protoplanetary disks, fragmentation and the radial drift of pebbles inhibit the growth of grains to planetesimals. To overcome these barriers, effective localized dust clumping on a short enough time scale is required. One promising solution to this problem is the streaming instability. Streaming instability is only triggered with a large enough dust-to-gas ratio and grain size. Though it is unknown when and where those conditions are met in protoplanetary disks, recent studies have indicated that planetary cores likely require early formation to match detected exoplanet system masses, so that we need to …

Memory Interference In The Lateral Entorhinal Cortex, Omar Ghazy

Dissertations, Theses, and Capstone Projects

Memory interference occurs when previously formed memories disrupt the acquisition or retrieval of new information. A prominent example of proactive interference is latent inhibition (LI), defined as a reduced ability to form or express Pavlovian associations with a stimulus following non-reinforced exposure. The interference-based model suggests that LI arises because the memory that the pre-exposed stimulus is inconsequential interferes with the memory that it predicts a reinforcer.

Because interference increases with age, identifying its neural basis may help prevent or slow cognitive decline. Prior studies using the LI paradigm implicate the entorhinal cortex (EC) in retrieving the memory that a …

Single Mother Poverty In A Global City, Gregory Cala

Dissertations, Theses, and Capstone Projects

The thesis explores how New York City's emergence as a "Global City" and welfare reform uniquely impacted single mothers’ lives on the matter of labor, housing, cost of living and more. New York City’s recovery from near bankruptcy in the 1970s began after cutting social programs and luring corporate firms with financial incentives. As firms moved to the city, so did their workforce of employees with skills in specialized service roles. Concurrently, the need for cheap, part-time, and temporary services emerged. By the 1990s, the growth of these less specialized service jobs outpaced all others, all while calls for work …

The Ethnobotany And Pharmacology Of Medicinal Plants For Caribbean Women’S Health, Ella Thomas Vardeman

Dissertations, Theses, and Capstone Projects

Approximately 55% of the world’s population lives in cities, and the United Nations estimates that this number will rise to 68% by 2050. Urban ethnobotany, the study of people’s traditional knowledge and use of plants in cities, is increasingly important as people adapt their cultural traditions to changing environments. In New York City (NYC), there have been several urban ethnobotany investigations in collaboration with Caribbean immigrant groups. However, there has yet to be an ethnobotanical survey that documents and botanically authenticates the medicinal plants used in the Haitian community. Previous collaborative research with women from the Caribbean in NYC has …

Parametrization Of Formal Norm Compatible Sequences, Joseph Dicapua

Dissertations, Theses, and Capstone Projects

We give a classification of power series parametrizing Lubin-Tate trace compatible sequences. This proof answers a question posed in the literature by Berger and Fourquaux. Lubin-Tate trace compatible sequences are a generalization of norm compatible sequences, which arise in Iwasawa theory and local class field theory. The result we prove generalizes the interpolation theorem proved by Coleman in the classical norm compatible sequence case. We also, jointly with Victor Kolyvagin, give a method for finding such series explicitly in certain special cases.

Elucidating The Roles Of Eukaryotic Initiation Factors Involved In Dap5 Mediated Translation, Jacob Nk Quartey

Dissertations, Theses, and Capstone Projects

Translation initiation in eukaryotes is a highly regulated process essential for accurate protein synthesis. It is a dynamic process that involves a complex interplay between messenger RNAs (mRNAs), ribosomal subunits, and a host of initiation factors, ensuring precise start codon selection and the subsequent assembly of the translation machinery. This process has well been known to be mediated by the eukaryotic Initiation Factor (eIF4F), which consists of the cap binding protein eIF4E, the scaffolding protein eIF4GI, and the helicase factor eIF4A.The recognition and binding of eIF4E to the m⁷G cap structure of the mRNA is essential for the …

Decoding The Plant Metabolome: A Metabolomics Approach To Guereza (Colobus Guereza) Feeding Ecology In Kibale National Park, Uganda, Emma Grace Thurau

Dissertations, Theses, and Capstone Projects

Plant metabolites, an elusive and diverse group of plant chemicals, represent a complex chemical interplay between plants and herbivores. Plants contain essential nutrients necessary for herbivore survival, yet herbivore consumption results in negative fitness consequences to a plant. This relationship has triggered a coevolutionary arms race in which plants have evolved chemical defenses to prevent herbivore consumption and herbivores, in response, have evolved their own counter-adaptations. This arms race has led to the diverse numbers of herbivores and plants observed today; therefore, these plant metabolites act as a signature of evolution through their influence on herbivore adaptations. Plant metabolites are …

Energy Conversion Materials: Computational Design Of Electrocatalysts Toward Sustainable Energy Applications, Courtney M. Brea

Dissertations, Theses, and Capstone Projects

As the global-scale need for sustainable energy technologies emerges due to anthropogenic climate change, electrocatalysis plays a crucial role in facilitating many sustainable processes. Several heterogenous cathode materials can perform different electrochemical activities using water, oxygen, hydrogen, carbon dioxide to deliver renewable electricity and value-added chemicals. By using the density functional theory method, it is possible to explore the structural and electronic properties that govern a catalysts’ activity and selectivity. In this thesis, we start by exploring 48 reconstructed transition metal dichalcogenides edges (MX₂, M = Mo, W; X = S, Se, Te) for carbon dioxide reduction reaction …

Re/Inventing Desire: Asexuality As A Tool For Utopian Intimacies, Amaranta Martinez Martinez

Dissertations, Theses, and Capstone Projects

Asexuality became widely known in 2001 when David Jay, launched the Asexuality, Visibility and Education Network (AVEN), however, it’s been just throughout the last decade that it has gained popularity among LGBTQ studies. This thesis explores asexuality beyond its conventional framing as a sexual orientation, positioning it instead as a theoretical framework with the potential to challenge hegemonic understandings of sexuality. It does so by tracing the historical construction of sexual desire through the discipline of sexology, demonstrating how its discourses helped reinforce compulsory sexuality—the expectation that individuals must experience and act upon sexual desire (Emens 2014). Building upon this …

The Unholy Matrimony: Russia And Violent Non-State Actors, Justin Castro

Dissertations, Theses, and Capstone Projects

Russia’s contemporary relationship with violent non-state actors has been at the forefront of news due to the conflict in Ukraine. Despite the international shock at this phenomenon, this is an age-old practice for Russia. Since the 17^th century, the Russian state has developed a strategy of utilizing violent non-state actors in order to achieve its geopolitical objectives that consist of expanding its territory, extending its influence abroad, and weakening the capabilities of adversaries. While this strategy seems clear-cut, it contains a rich history of Russia trying to manage its relationship with non-state actors from a position of weakness and …

Tradwives: The Housewifization Of The Girl Boss, Gagan Kaur

Dissertations, Theses, and Capstone Projects

This thesis examines the reemergence of a particular performance of domesticity in the post-pandemic era, focusing on the rise of the "tradwife" (traditional wife) movement alongside the normalization and spread of Alt-Right ideology through popular social media platforms. It argues that the tradwife is not a return to tradition, but a commodified performance of domesticity built on the erasure of social reproductive labor. Tracing the lineage of the “housewife” from the enclosure of the commons to imperial domesticity and from the “girl boss” to tradwife influencer culture, this project situates the tradwife within a longer history of "housewifization"—wherein women's labor …

Belonging Against The Odds: Exploring Restorative Justice Practices As Pathways To Foster Belonging In New York City Transfer Schools, Miguel Rodriguez

Dissertations, Theses, and Capstone Projects

The U.S. education system perpetuates structural inequities that disproportionately affect Black students with the School-to-Prison Pipeline (STPPL) criminalizing them through Zero-Tolerance policies. Transfer schools are often a last resort for students pushed out of traditional schools provide a lens to examine the impact of Restorative Justice Practices (RJP) and Black student representation on belonging. This quantitative dissertation study analyzes secondary data from the NYC Department of Education using multivariate models to explore the relationship between RJPs and sense of belonging (SOB). Model 1 found that discussing feelings and emotions at school (Tier 1 RJP) had the strongest association with SOB …

Deuce Redemption: Grindhouse Cinema, Moral Panic, And Urban Renewal, Robert Brenner

Dissertations, Theses, and Capstone Projects

If you consult standard histories of the “redevelopment” of 42^nd Street between Seventh and Eighth Avenue, AKA “the Deuce,” you will read that it was filled with nothing but criminals and pornographers, that decent people avoided it at all costs, and the only way the block could be “saved” was by seizing it via eminent domain, evicting all the current tenants, and replacing them with Disney and its fellow entertainment corporations.

The purpose of this thesis is to offer a more nuanced alternative to these standard histories. I will argue that the Deuce was a lower-class, multiracial, queer entertainment …

Consequences Of Oxidative Dna Damage: Base-Pair Dissociation, Singlet Oxygenation And Dna-Protein Crosslinking, May Myat Moe

Dissertations, Theses, and Capstone Projects

8-Oxo-2′-deoxyguanosine (OG) is a common DNA lesion resulting from oxidatively generated damage and pairs with complementary cytidine (C) in Watson Crick base-pairing within duplex DNA. The WC-OG·C lesion, if not recognized or repaired, not only leads to G⋅C→T⋅A transversion mutations (through Hoogsteen (HG) base pairing of OG⋅A), but also renders the base pair being more vlunerable to ionizing radiation and singlet oxygen (1O2) damage. Leveraging on our previous accomplishments on the study of gas-phase reactions of 1O2 with 2′-deoxyguanosine radical cations, my research thesis expanded to the investigation of reaction dynamics of 9-methyl-8-oxoguanine (9MOG) radical cations. The experiments of following …

The Role Of Acculturative Stress, Discrimination In Healthcare Settings, And Migration-Related Trauma On Hiv Prevention And Mental Health Among Immigrant Hispanic Sexual Minority Men: An Integrated Model Of Acculturation And Minority Stress, Jonathan Lopez Matos

Dissertations, Theses, and Capstone Projects

This dissertation expands Minority Stress Theory (MST) by integrating the Fourfold Acculturation Model (FAM) to examine the impact of psycho-sociocultural stressors on health outcomes among immigrant Hispanic sexual minority men (HSMM) in the U.S. The study explored how language proficiency, acculturative stress, discrimination in healthcare, migration-related trauma, and stress-related growth influence HIV prevention behaviors and mental health. Survey data from 194 Spanish-speaking immigrant HSMM revealed that monolingual Spanish speakers experienced significantly higher acculturative stress than bilinguals. Acculturative stress significantly mediated the association between stressors and health outcomes, such as HIV testing and mental health symptoms. Discrimination and trauma were directly …

The Role Of Secondary And Tertiary Structure In The Cap-Independent Translation Of Fgf-9 And Hif-1-Alpha, Amanda Michelle Whittaker

Dissertations, Theses, and Capstone Projects

Under normoxic conditions, eukaryotes initiate translation of RNA through eIF4E recognition of the 5’ cap. However, under cellular stress, eukaryotic translation must be initiated through a 4E-independent, or “cap-independent” mechanism, involving eukaryotic initiation factor 4G (eIF4G) binding directly to the 5’ untranslated regions (5’ UTR) of the RNA. eIF4G binding then recruits the ribosome to the transcript. While this mechanism is useful for translation of apoptotic transcripts and transcripts involved in cell survival, cap-independent translation is also utilized by oncogenic RNA for tumorigenesis. Previous work by our lab and others has categorized this recruitment and initiation mechanism as either internal-ribosome-entry-site …

The Double Victimization Of Black Women At The Crossroads Of Oppression, Carmerina Carrero

Dissertations, Theses, and Capstone Projects

The purpose of this research study is to amplify the voices of Black women and shed light on the invisibility of Black women’s struggle with police violence and the criminal justice system. The study seeks to expose the different forms of systemic oppressive mechanisms that target Black women, such as mass incarceration and police violence. Through the lenses of intersectionality and critical race theory, the study will explore how racism and sexism contribute to the victimization of Black women via our criminal justice systems and law enforcement. Highlighting the unique experiences of Black women navigating through the criminal justice system, …
