Tongues Out Of Place: Narratives Of Hereness And Images Of Be(Long)Ing, Christopher Hoffman

Dissertations, Theses, and Capstone Projects

What is the role of the psychologist during times of gentrification, climate change, and inequity? Using Hall & Massey’s (2010) term conjunctural crisis, or the overlapping of multiple disasters that bleed into each other, I argue that psychologists have a responsibility to combat social inequity and work towards tangible strategies in collaboration with communities to dismantle structures of oppression. In times of gentrification and climate change, I argue that psychologists must play a role in promoting public science, a praxis of research committed to applying social science with communities in order to work towards social justice and build a more …

Evaluation Of Symmetric Functions And Boolean Functions Over Stochastic Input, Naifeng Liu

Dissertations, Theses, and Capstone Projects

In our daily life, we often face situations where we need to make precise judgments based on initially unknown information, while gathering all the evidence to make informed conclusions can be very costly. In this dissertation, we explore the problem of optimizing the decision-making process under uncertainty, and we focus on problems that can be found in both theoretical computer science and discrete mathematics. The primary goal is to develop approximation algorithms with guaranteed worst-case performance. These algorithms aim to minimize the expected cost of acquiring information necessary for evaluating fundamental functions, such as Boolean and symmetric functions. Furthermore, we …

Evocative Visualization Of Void And Fluidity, Tomiko Karino

Dissertations, Theses, and Capstone Projects

In the last few years alone, we have seen a significant increase in a demand for inclusion and diversity in every sector in our society. While there are numerous data visualization projects that point out and raise concerns about the lack of diversity, they often merely illustrate the disparity. By using the permanent collection data of the Museum of Modern Art, this capstone project explores ways to creatively visualize gender disparity among the artists in the museum’s collection and questions what makes evocative visualizations that make an impression on the audience. It examines how to create visualizations that not only …

Characterization Of The Conformational Binding Of N-Methyl Mesoporphyrin Ix With Dna Model Telomeric G-Quadruplex Forming Sequences, Jessica Desamero

Dissertations, Theses, and Capstone Projects

DNA G-quadruplexes are alternative secondary structures formed from guanine rich DNA sequences. G-quadruplexes are found most abundantly at the ends of chromosomes called telomeres, where they can ultimately prevent further tumor growth and progression. Thus, quadruplex interactive agents, or ligands that can bind to and stabilize DNA G-quadruplex structures, are of high interest for their potential chemotherapeutic abilities. One quadruplex interactive agent is the porphyrin N-methyl mesoporphyrin IX (NMM), which has high binding selectivity for quadruplex structures. While the NMM-quadruplex complex in crystallized form has been greatly studied, this complex in solution form is not as well studied. Through circular …

Africa’S Coastal Archaeological Record And Climate Change, Michael Murphy

Dissertations, Theses, and Capstone Projects

Since the 1980s, archaeologists have warned about threats from anthropogenic climate change (ACC) to the world’s archaeological record in coastal areas. Until recently, such warnings did not include Africa’s archaeological record. There is a persistent gap in research on climate change and Africa’s archaeological and cultural heritage stretching back before the U.N. established the Inter-governmental Panel on Climate Change (IPCC) in 1988. The purpose of this thesis is to assess the gap and help to narrow it. The approach is to take advantage of the availability of the dataset from the first geographically comprehensive study of climate change and coastal …

Doc/U/Ment: Affinities In 20th And 21st-Century Documental Poetics, Katherine Payne

Dissertations, Theses, and Capstone Projects

This dissertation presents, analyzes, and builds on the existing literary genealogy of documental poetry. In 2020 Michael Leong proposed the term documental poetry to describe the turn toward source materials in 21^st-century North American poetry, seen in longform research-based poems that explicitly incorporate documentation and seek to intervene in cultural memory. Using Ludwig Wittgenstein’s concept of family resemblance, I argue that there are clear affinities between 21^st-century poets and their 20^th-century literary forerunners, also that an expansion of the scope of documental poetics is needed. The three nodes of connection I examine are works …

The Development Of Novel Radioscandium And Hydroxypyridinonate Based Radiopharmaceuticals, Michael Phipps

Dissertations, Theses, and Capstone Projects

The use of radiometals in radiopharmaceutical development has drastically increased over the last decade, owed in part to the diverse chemistry and emission characteristics of the radiometals, which allow chemists to create a toolbox of agents to better tailor patient care. Challenges with the use of radiometals include the selection of the metal and the development of optimized chelators to cover the diverse chemistry of the metals which make up the majority of the periodic table. Scandium is the first transition metal and has multiple radioisotopes whose emission characteristics have potential application in medicine. 3,4,3-LI(1,2-HOPO) is a chelator whose denticity, …

Fuglede's Conjecture establishes a profound connection between the geometric property of being a tiling set and the analytical attribute of being a spectral set. By exploring the conjecture on various discrete settings, this thesis delves into the implications and ramifications of the conjecture, unraveling its implications within the field.

Nonlinear Processes In Room Temperature Exciton-Polaritons, Prathmesh Deshmukh

Dissertations, Theses, and Capstone Projects

Strong light-matter coupling in solid state systems is an intriguing process that allows one to exploit the advantages of both light and matter. In this context, microcavities have become essential platforms for studying the strong coupling regime, where hybrid light-matter states known as exciton-polaritons form, leading to enhanced light matter interaction, modified material properties, and novel quantum phenomena. In this thesis, we explore the phenomenology of exciton-polaritons in strained TMD microcavities, 2D perovskites, fluorescent proteins and organic dyes encompassing thermalization, polariton lasing, and the observation of nonlinear effects.

Transition metal dichalcogenides (TMDs) have emerged as a remarkable class of two- …

Form In Hip-Hop Music: Sections, Songs, And History, Stephen M. Gomez

Dissertations, Theses, and Capstone Projects

This dissertation explores musical form in recorded hip-hop music from 1979–present. Form, defined as the large-scale organization of songs, is a parameter that artists consider in the creative process and fans experience while listening. Hip-hop’s historical foundation as a live, improvised, party-oriented genre influenced formal functions and patterning from the earliest days of its popular recorded life, beginning with the Sugar Hill Gang’s “Rapper’s Delight” in 1979. While many of the section and song form labels used by scholars of pop-rock music are transferable to the analysis of hip-hop, the latter genre conveys a unique sense of time rooted in …

Parallel Processes Of Posttraumatic Stress And Metabolic Dysfunction: Long-Term Costs Of Trauma On The Psychological And Physical Health Of 9/11 Survivors, Shane W. Adams

Dissertations, Theses, and Capstone Projects

Metabolic conditions (MetC) have been associated with posttraumatic stress disorder (PTSD) symptoms and may be critical indicators of the systemic physical sequelae of traumatic stress. Parallel process latent growth modeling wasapplied to longitudinal data collected from 35,788 9/11 survivors and used to model PTSD symptoms and MetC to determine how the development and course of one affect the other. A unidirectional relationship was found in which the intercept of PTSD symptoms predicted the slope of MetC. Hyperarousal (ß=.172) and emotional numbing (ß=.171) PTSD symptoms demonstrated the strongest association with the growth of MetC over and above …

A Blackgirl Artivisionary Mosaic: Art-Based Participatory Refusals To School Punishment, Tyese A. Brown

Dissertations, Theses, and Capstone Projects

The study participants were co-research partners and engaged in a Project Based Learning six-week summer project in an urban northeastern metropolis community-based non-profit where they received stipends for participation. This dissertation explored how Blackgirls (aged 14 -21) express their experiences with disparate school punishment through community-based participatory artmaking. We called the photos, poems, collages, sculptures, storyboards, digital art, visual art, songs, spoken word, and videos Artivisions (art I vision). In the Jam Sessions, a subset of the partners we called curators discussed the pieces, shared their experiences, and offered insight into Blackgirls’ responses, coping skills, and decision-making regarding school punishment. …

Gendered Care Work And State Ambivalence: Disaster Recovery And Puerto Rican Displacement In New York City, Lisa Jahn

Dissertations, Theses, and Capstone Projects

This dissertation traces the politics of disaster recovery and coloniality in New York City, documenting the forms of ambivalent care that characterize institutionalized disaster recovery programs. I examine how Puerto Ricans arriving in New York City post- hurricane María navigate the racialized and inadequately funded recovery aid program supported by the Office of the Mayor of New York City. Following the events of September 11, 2001, New York City faith-based agencies established programs to assist in rescue, relief, and recovery efforts. The New York City Relief Center (NYRC) was first incorporated in 2003 to address all phases of the disaster …

Party Time: The Working Families Party And The Us Political System, 1998–2018, Luke P. Elliott-Negri

Dissertations, Theses, and Capstone Projects

In 1998, an upstart “third party” called the Working Families Party (WFP) limped onto the political scene in New York State. Ten years later, the WFP was at the center of the electoral effort that wrested control of the New York State Senate from the Republican Party for the first time in many decades, and a torrent of progressive legislation ensued. This dissertation is a history of the WFP from 1998 to 2018, when the Republicans were again—and this time stably—vanquished at the state level and socialists began to enter state and federal office in a new way. To develop …

Optimization And Application Of Graph Neural Networks, Shuo Zhang

Dissertations, Theses, and Capstone Projects

Graph Neural Networks (GNNs) are widely recognized for their potential in learning from graph-structured data and solving complex problems. However, optimal performance and applicability of GNNs have been an open-ended challenge. This dissertation presents a series of substantial advances addressing this problem. First, we investigate attention-based GNNs, revealing a critical shortcoming: their ignorance of cardinality information that impacts their discriminative power. To rectify this, we propose Cardinality Preserved Attention (CPA) models that can be applied to any attention-based GNNs, which exhibit a marked improvement in performance. Next, we introduce the Directional Node Pair (DNP) descriptor and the Robust Molecular Graph …

Theorizing Racial Democracy, Teófilo De Souza Carmo Reis

Dissertations, Theses, and Capstone Projects

The critical philosophy of race has shown recent growth, but it tends to focus too much on the United States. This leaves many race-related concepts and phenomena from other parts of the world underexplored. I help to fill this gap by exploring the idea of "racial democracy" in Brazil, which is a form of racial ignorance that is prevalent in that country. Specifically, I am interested in the epistemic aspects of this mechanism of creating and propagating racial ignorance.

To achieve this goal, I begin by introducing Charles Mills' concept of white ignorance and other influential works in social epistemology. …

Regulating The Care Boom: Labor Standards Enforcement And Paid In-Home Care Work, Isaac Jabola-Carolus

Dissertations, Theses, and Capstone Projects

In the United States, population aging has driven explosive growth in care-sector occupations, especially among low-wage home care aides who provide long-term assistance to older adults. These aides, predominantly women and disproportionately people of color, now represent one of the country’s largest and fastest-growing occupational groups. In recent decades, economic inequality and meager social policies have also spurred demand for nannies, housecleaners, and other domestic workers—occupations heavily reliant on immigrant women, many undocumented. While scholarly and public discourse has addressed labor shortages and job quality in such occupations, a related problem is the widespread violation of labor standards, including minimum …

Essays In Health Economics, Chuxin Liu

Dissertations, Theses, and Capstone Projects

In Chapter 1, I investigate the effect of a financial incentive from the Centers for Medicare and Medicaid Services (CMS) on new medical procedure technology diffusion. I examine how the incentive affects diffusion among Medicare patients, for whom hospitals receive the incentives, and non-Medicare patients for whom there are no incentives. I answer these two questions by studying the New Technology Add-on Payment (NTAP) program offered by Medicare (Part A). It is unknown whether its incentive is enough to encourage diffusion under the prospective payment system and it also remains unknown whether it spills over to non-Medicare patients or crowds …

Ambivalent Scales: Methods For Reading Scenes Of Sexual Violation, Natalie Ruby

Dissertations, Theses, and Capstone Projects

The importance of unveiling rape in the #MeToo era has unintentionally obscured encounters that lack the clarity of “yes” or “no.” However, desire can be ambiguous even in unambiguous cases of assault. Feminist activists and scholars have started to address ambiguity by arguing for a new epistemology of rape, what Linda Alcoff calls “grey rape.” In this thesis, I interrogate the “grey” embedded in ordinary sexual encounters by looking at ambivalence as an example of everyday desire evident across the seduction plot and the novel tradition. Rather than seeking to make consent more inclusive to oppressed groups, I read between …

Centrality Effects On Heavy-Flavor Quark Production And Invariant Yield In Phenix Proton–Gold Collisions At Center-Of-Mass Energy 200 Gev, And Assembly, Testing, Calibration, And Installation Of The Sphenix Hadronic Calorimeters, Daniel Richford

Dissertations, Theses, and Capstone Projects

Hadrons created in heavy-ion collisions interact with the open color-charge of the quark-gluon plasma through their constituent quarks. The medium imparts substantial modifications to heavy-flavor hadrons' momentum spectra. For collisions of small systems, the centrality of those collisions affects both the production of heavy-quarks and the medium modifications that the heavy-quarks experience. This analysis uses the PHENIX detector at the Relativistic Heavy Ion Collider, which collected data from proton--gold collisions in 2015, with a trigger to preference the collection of the five-percent most-central collisions. This analysis uses the distance-of-closest-approach of electron tracks to study semileptonic decays from charm and bottom …

Rotation Period Distributions And Light Curve Morphologies Of Low Mass Stars And Young Associations, Mark Popinchalk

Dissertations, Theses, and Capstone Projects

This dissertation is centered around the rotation periods of low-mass stars and association of young stars. Rotation periods are a link to the age of the star, as they lose angular momentum over time. To understand how this angular momentum evolves requires understanding the rotation period distributions of a range of stellar types and ages. Traditionally, M dwarf stars and young stars were challenging to describe due to their intrinsic faintness and dispersed sky positions respectively. I approached this subject from several directions.

Additionally, the research assesses the range of library services the system provides, encompassing diverse educational initiatives and opportunities for civic involvement, all aimed at fostering a more …

From Allegory To Revolution: The Inca Empire In The Eighteenth-Century French Imagination, Agnieszka A. Ficek

Dissertations, Theses, and Capstone Projects

Péruvienophilie was one of the many exoticisms that emerged in eighteenth-century Europe. It was born out of the French desire to build an outpost of their colonial empire in South America, a desire that was thwarted several times in the sixteenth and seventeenth centuries. This dissertation examines French portrayals of the Inca and their transatlantic impact. It is an interdisciplinary project with strong literary, sociological, historical, and anthropological dimensions but grounded in a rich visual culture. French prints and paintings, stage sets and costumes, porcelain figures, and panoramic wallpapers promulgated the image of an exotic land inhabited by a Native …

Establishing A Mouse Model Of Glioblastoma (Gbm) And Developing Strategies To Eliminate Cancer Cells., Juliet N.E. Baidoo-Kanneh

Dissertations, Theses, and Capstone Projects

As the tenth leading cause of cancer death in the United States with a 6.8% five-year survival rate, glioblastoma multiforme (GBM) is a very deadly disease with a poor prognosis. Therefore, a curative treatment is in high demand. Among the widely used anti-metabolites (Chemotherapeutic agents, CAs), each compound approved for human use by the Food and Drug Administration (FDA) has side effects. Three main phenomena contribute to the side effects and the reappearance of cancer: (a) the cancer cells become resistant to chemo- and radiation therapy; (b) this chemo-resistance prompts the use of higher doses of the chemotherapeutic agents; and …

Separation Of Zr From Complex Matrices For Isotope Harvesting Applications, Jake A. Bence

Dissertations, Theses, and Capstone Projects

Zr isotopes have various applications in nuclear science, such as ⁸⁶Zr and ⁸⁹Zr in nuclear medicine, ⁸⁸Zr as a diagnostic isotope relevant to stockpile stewardship, and the fission product ⁹⁵Zr useful as an s-process branch nucleus for study in astrophysics. To access these isotopes of interest, dedicated production methods and subsequent processing chemistry are required. Direct production routes can be technically challenging and difficult to obtain enough activity to meet demand. The processing chemistry of Zr isotopes is tedious due to the tendency for Zr to hydrolyze in solution without highly acidic conditions or a strong …

Tunable Linear And Nonlinear Metasurfaces Based On Hybrid Gold-Graphene Plasmons, Matthew Feinstein

Dissertations, Theses, and Capstone Projects

Optical Metasurfaces are planar structures that are patterned with subwavelength structures and are very thin compared to the wavelength of light. Despite their thinness, these structured materials can strongly interact with incident light to effect the functionalities of conventional optical components, such as rotation of the polarization state, beam steering, lensing, spectral filtering, and holography, to name a few. Metasurfaces can also facilitate nonlinear optical effects, such as the mixing of beams at different frequencies to generate a beam at a new frequency.

The ability to alter the behavior of a metasurface during operation is highly desired for applications such …

Rewiring The Spokes: The Future Of U.S. Bilateralism In Asia, Gian Marc Lombardo

Dissertations, Theses, and Capstone Projects

Since the end of WWII, multilateralism has consistently grown as the go-to alliance structure for the United States. Despite this, the U.S. opted to create a series of bilateral alliances after WWII in Asia, dubbed the Hub-and-Spokes system. This alliance system has not only sustained itself, but also continues to fortify itself in the face of a rising threat in Asia. China has increased its assertiveness and has shifted the balance of threat in the region, while also being the primary economic and development option for regional states. This major change in the structure of Asian power has surfaced the …

Raphael Montañez Ortiz And Alternative Art Spaces, 1966–1971: From Repulsion To Exaltation, Ana Cristina Perry

Dissertations, Theses, and Capstone Projects

In the 1960s, Brooklyn-born Puerto Rican artist Raphael Montañez Ortiz built a successful and provocative career in New York. Throughout the decade, Ortiz created sculptures, performances, and events that were part of a sustained investigation into how embodied destructive and uncomfortable actions could physically confront rationality and objectivity. His works attend to how rationality and objectivity were valued in the United States as a consequence of colonization and imperialism. Beginning in 1969, Ortiz overtly addressed how museums are directly implicated in systems of oppression, protesting with the Art Workers Coalition and founding El Museo to meet the needs of the …

Towards Interpretable Machine Reading Comprehension With Mixed Effects Regression And Exploratory Prompt Analysis, Luca Del Signore

Dissertations, Theses, and Capstone Projects

We investigate the properties of natural language prompts that determine their difficulty in machine reading comprehension tasks. While much work has been done benchmarking language model performance at the task level, there is considerably less literature focused on how individual task items can contribute to interpretable evaluations of natural language understanding. Such work is essential to deepening our understanding of language models and ensuring their responsible use as a key tool in human machine communication. We perform an in depth mixed effects analysis on the behavior of three major generative language models, comparing their performance on a large reading comprehension …
