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.

The Warmth Of Welcome Of Refugees And Migrants In The Western Balkans, Zylfie Demushi

Dissertations, Theses, and Capstone Projects

Despite it getting harder to immigrate to the EU legally, refugees from the global south still try to immigrate to developed countries in the EU through transit states in the Balkan region. In search of refuge from wars, better economic prospects, or family reunions, over the past decade, many migrants have attempted to travel North through transit states like North Macedonia, Albania, and Montenegro. A qualitative study was conducted following a theoretical approach by Adamson and Tsourapas (2019), who categorized migration states in the global south into three types, i.e., nationalizing, developmental, or neoliberal. The paper followed this approach to …

The "Self" In Crisis: A Study Of Audre Lorde's The Cancer Journals, Golnaz Salehkarimi

Dissertations, Theses, and Capstone Projects

In this thesis, I focus on The Cancer Journals and explore how Audre Lorde articulates the chaos followed by breast cancer in her life: what is the nature of the crises? What aspects of her life are largely affected by it? How it unsettles her understanding of time and place, how her daily life, work, relationships, and future plans get affected, and how her self-image and her agency and subjectivity are threatened. Relying on theories of women’s autobiographies, women’s writings, and illness narratives, I explore Lorde’s ways of writing about her body and emotions to regain her sense of self …

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 …

The Reimagined Past: Investigating Generational Trauma Through Visual Semiotics And Visual Autoethnography Of Recreated Family Photographs, Josephine A. Barnett

Dissertations, Theses, and Capstone Projects

Family photographs, and particularly the curation of family photo albums, serve as a source of data, providing researchers with the opportunity to illustrate the role of the visual in reproducing certain social norms and ideals by dictating the depiction or representation of specific types of families and experiences. Arguably, what is left outside the frame of a photograph is more revealing about familial norms, memory, and narrative than what is deliberately captured within it (Hirsch, 1997a; Kuhn, 2002a). In other words, the hegemony and standardization of family photos shed light on the need for an alternative visual narrative that depicts …

Tracing My Roots: An Exploratory Data Visualization And Analysis Of Jewish Immigration And Assimilation To New York City, Jamie E. Gelberg

As my Capstone, I explored the complex process of immigrant assimilation to New York City from the late 19th century and beyond through a personal lens, using my Ashkenazi Jewish family as a case study.

I outlined and analyzed relevant demographic data from the US Census Bureau, Berman Jewish DataBank, and other sources to understand New York City during this period and how Jewish immigrants fit into the story. I focused on my family history, immigration and settlement, social assimilation, and economic status. I also incorporated personal narratives from my family history from 3 generations. These narratives help provide context …

Transmedial Econarratology: Environment And The Subject Of Science Fiction, Joseph R. Boisvere

Dissertations, Theses, and Capstone Projects

This dissertation argues that narrators are constructed by their interactions with diegetic space and time in an ecological relationship. This argument draws upon Erin James’s work on econarratology, particularly her book The Storyworld Accord: Econarratology and Postcolonial Narratives, putting her theories of narrating time and place in dialogue with contemporary “unnatural” narratology as theorized by scholars such as Jan Alber and Brian Richardson. Science fiction (SF) offers a rich complement to these theoretical stances. I also focus much of my dissertation on how narratology works across and is influenced by specific media, featuring literary, audiovisual, and digital media, including novels, …

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 …

Global Constructions Of Gender, Sexuality, And Migration: An Analysis Of Five Immigrant Memoirs, Grace Halvorson

Dissertations, Theses, and Capstone Projects

This capstone analyzes five memoirs by LGBTQ+ migrants—Jose Antonio Vargas, Edafe Okporo, Staceyann Chin, Danny Ramadan, and Samra Habib—to explore how governments weaponize gender and sexual orientation to construct national identity and exert control over both citizens and migrants. Their diverse migration experiences highlight how “gender border control” operates across families, communities, and national government systems, reinforcing heteronormative structures that regulate queer identities. My analysis of their memoirs reveals how both formal tools, such as immigration policies, and informal tools, such as social exclusion, make individuals outside heteronormative identity categories susceptible to state and societal violence. These personal narratives shed …

Parvalbumin Interneuron-Oligodendrocyte Interactions In The Infralimbic Cortex Promote Extracellular Plasticity Mechanisms After Safety Learning, Lucy Emma Denholtz

Dissertations, Theses, and Capstone Projects

The ability to differentiate between threat and safety cues is essential for adaptive behavior, yet this process is disrupted in psychiatric disorders, such as post-traumatic stress disorder (PTSD), where safety cues fail to downregulate fear expression. To better understand the neurobiological mechanisms of safety learning, I investigate how safety conditioning vs contextual fear conditioning modify behavioral and cellular mechanisms in the infralimbic (IL) region of the medial prefrontal cortex (mPFC) at several time points after learning. Through this work, I identify a novel mechanism whereby safety learning promotes learning dependent neuro-glial interactions that promote conditions for plasticity in the mPFC. …

Nonlinear Physics Of Parity-Broken Fluids, Sudheesh Srivastava

Dissertations, Theses, and Capstone Projects

This thesis explores parity-breaking mechanisms, nonlinear wave phenomena, and localization transitions across different physical contexts. First, we examine modulation instability in parity-breaking systems, deriving modified nonlinear Schr¨odinger equations that reveal direction dependent instabilities. Next, we investigate wave turbulence, demonstrating numerically that parity-breaking dispersion significantly alters turbulent cascades and modifies their statistical properties. Lastly, we analyze localization in quasiperiodic tight- binding model based on polariton condensate lattice. Collectively, these studies illustrate the universal role of symmetries and nonlinear interactions in shaping macroscopic behaviors, facilitating interdisciplinary insights.

Self-Reported Audiological And Vestibular Symptoms Associated With Lyme Disease, Daniella A. Bryan

Dissertations, Theses, and Capstone Projects

Background:

Lyme disease, an infectious vector-borne illness, is carried by the deer tick, Ixodes scapularis, which harbor the spirochete, Borrelia burgdorferi, affecting hundreds of thousands of people in the United States annually. Lyme disease has a multitude of clinical presentations and overlaps with other complex illnesses, making diagnosis and treatment a medical challenge. This distinct bacterium can migrate into any organ system through the mediums of soft tissue, the lymphatic system, and the circulatory system. Despite its prevalence and range in symptomatology, minimal research has been conducted to identify distinct audiological and vestibular symptoms associated with a Lyme …

A Novel Closed Monoidal Structure On The Nucleus Of A Profunctor, Samantha K. Jarvis

Dissertations, Theses, and Capstone Projects

We describe a novel closed monoidal structure on the nucleus of a profunctor enriched over a posetal category, a distinguished subcategory of the category of presheaves given by the invariant part of an adjunction induced by the profunctor. Our structure is motivated by a connection to a notion of type given by orthogonality. For specific examples, we consider the two-element enriching category {0,1} and the reals.

Breaking Out Of Burnout: Leveraging Informal Learning To Encourage Needs Satisfaction To Reduce Employee Burnout, Kaitlin Busse

Dissertations, Theses, and Capstone Projects

Given its negative effects on employees and organizations, burnout is seen as a crucial concern in the workplace. To combat burnout, researchers and organizations have explored some individual-level strategies to manage work-related stress effectively. An overlooked employee-driven strategy is informal learning within the workplace. While existing research has focused on learning outside work hours for stress recovery, the current study examined whether informal learning at work is a beneficial proactive behavior for employees to help alleviate stress in real-time, and thus, potentially reducing burnout. Specifically, the current research was interested in whether employees’ psychological needs at work would be satisfied …

Environmental Enrichment Reduces Cue-Induced Reinstatement Of Heroin-Seeking Following Prolonged Use And Reverses Region-Specific Heroin-Induced Neuroadaptations, Apoorva Vashisht

Dissertations, Theses, and Capstone Projects

Background: Relapse remains the greatest barrier to long-term recovery and the consequential rising overdose-related mortality in heroin use disorder (HUD). Currently available behavioral and pharmacological interventions fail to extend their benefits beyond the duration of the treatment. Additionally, opioid agonist-based medications accompany harmful neurobiological risks and propensity to promote further drug-seeking post-treatment. We have shown that environmental enrichment (EE), as a therapeutic strategy applied after drug intravenous-self administration (IVSA), can effectively facilitate abstinence and reduce reinstatement of drug-seeking in animal models of drug abuse. Moreover, dopamine receptors like D1 and D3, and mu-opioid (MO) receptors are well known for their …

Disturbance And Diversity: Lichens In Changing Landscapes, Laura Boggess

Dissertations, Theses, and Capstone Projects

Disturbance is a fundamental ecological force that shapes biodiversity, community composition, and ecosystem function. Human-driven disturbances—such as habitat fragmentation, deforestation, and air pollution—are increasing worldwide, altering ecosystems at unprecedented rates. While ecological research has illuminated many effects of disturbance, significant knowledge gaps remain for underappreciated but ecologically vital organisms, such as lichens. Lichens are obligate symbioses between at least one fungus and one alga or cyanobacterium. As such, they are sensitive bioindicators of environmental change, offering unique insights into ecosystem health due to their responses to stressors such as poor air quality, habitat fragmentation, and deforestation. Yet, their responses to …

When Avatars Go To School: The Effect Of Virtual Reality On Learning And Error Correction, Lauren Barack

Dissertations, Theses, and Capstone Projects

The pandemic in 2020 led to an increasing dependency on technology particularly in learning environments. National educational assessments in the proceeding years have indicated steep, measurable learning loss. While a fully virtual learning environment is not the norm today, we chose to investigate how virtual reality (VR) environments influence learning in college students.

Our primary research goal was to look at how students learn and remember information gathered in virtual spaces. In particular, we examined whether sensory inputs in the VR environment, including spatial audio and haptic feedback, such as vibrations felt in a handheld controller, would help to better …

Placemaking And Belonging In Brooklyn: Bushwick City Farms, Marisa Cigliano

Dissertations, Theses, and Capstone Projects

Since the spring of 2022, New York City has seen an increased rate of newly-arrived migrants from countries in Latin and Central America, Asia, and Africa. In accordance with the city’s “right to shelter” obligation, NYC has provided shelter for migrants by converting hotels, office buildings, and even tents, into make-shift lodging designed for temporary stay. Within a year, anti-immigrant rhetoric from Mayor Eric Adams sparked activism from both immigrant rights organizations and long-term residents who don’t want migrant shelters in their neighborhoods. These shelters lack the necessary food, privacy, social services, and structure that is owed to homeless residents …
