The Cranial Nerves And Electrical Stimulation, Devin K. P. Adair

Dissertations, Theses, and Capstone Projects

Cranial nerves provide afferent pathways that enable bottom-up modulation of central autonomic and cognitive neural pathways. Because these pathways project to brainstem nuclei such as the nucleus tractus solitarius and engage neuromodulatory systems, including the locus coeruleus, electrical stimulation offers a mechanistically grounded approach to influencing brain function. This thesis tested whether active transcutaneous auricular vagus nerve stimulation (taVNS) produces physiological responses indicative of parasympathetic engagement, defined as decreases in heart rate, increases in heart rate variability, and decreases in respiration relative to a dose-matched earlobe control condition. Using cardiac and respiratory measures as physiological markers, taVNS at the tragus …

Model-Theoretic Arguments In Philosophy, Peter Susanszky

Dissertations, Theses, and Capstone Projects

This dissertation is on model-theoretic arguments in philosophy, especially those of Quine, Davidson, and Putnam. In the first part, to ground the debate, I give a rigorous introduction to the salient parts of first-order model theory. I start the second part by giving an introduction to Quine's philosophy, and how the model-theoretic arguments fit into it. After considering how Donald Davidson adopted the Quinean lesson, I move on to Putnam's model-theoretic arguments. Putnam's spin on these model-theoretic considerations significantly departs from Quine and Davidson, while retaining many of the core ideas. Most importantly, I argue that the target of Putnam's …

Teaching Third Graders To Read Multisyllable Words: Segmentation Versus Whole Word Reading, Jolie D. Heath

Dissertations, Theses, and Capstone Projects

In the early years of elementary school when children are still learning to read, they are presented with words of increased syllable length, and orthographic and morphological complexity in the texts they read.  Although multisyllabic words comprise 90% of words in the English lexicon and carry important linguistic information for expanding vocabularies and comprehension of content, few studies have focused on teaching middle elementary children to read multisyllabic words.  Many children lack strategies to identify these longer more complex words accurately and easily, leading to reading difficulties that place weaker readers at higher risk for school related problems and limit …

Social And Structural Factors In The Development Of Baltimore's Low Back Vowels, Aidan J. Malanoski

Dissertations, Theses, and Capstone Projects

This dissertation is concerned with the low back vowels of Baltimore English: what low back systems occur, and how these systems have changed among Black and white Baltimoreans. I draw on two sources of data: 48 interviews that I conducted with natives of Baltimore and its inner suburbs, and 18 oral history interviews that were conducted from 1978 to 1981. In Chapter 3, I argue for the inclusion of the pre-rhotic sets START and NORTH in typologies of English low back vowels. With these sets included, several previously unattested low back systems are found in Baltimore. These are united by …

Social Media-Based Social Comparisons Among Socially Anxious Young Adults: The Role Of Cognitive Reappraisal, Jennifer L. De Rutte

Dissertations, Theses, and Capstone Projects

Social media is a central context for social interaction and self-evaluation among young adults. For those with elevated social anxiety, these environments may be especially salient because they provide frequent opportunities for social comparison. Although upward social comparison on social media has been linked to poorer emotional outcomes, less is known about its experimental effects among socially anxious young adults or whether upward and downward comparison have distinct effects that extend to later socially evaluative situations. The present study examined these questions in 84 socially anxious young adults randomly assigned to view simulated Instagram feeds eliciting upward comparison, downward comparison, …

Vibe Diggers: The Sampling Of Brazilian Music In Hip-Hop, Romulo De Carvalho Moraes Barbosa

Dissertations, Theses, and Capstone Projects

This dissertation investigates the trend of musical borrowings of 1970s MPB (música popular brasileira) by contemporary American hip-hop producers, especially in terms of what they have called a “Brazilian vibe.” A lot has been said about sampling already from legal, sociological, and historical points of view, but less has been said about its aesthetic procedures, and even less about the wider implications of a tendency for using transnational sources. In the case of MPB, hip-hop artists seem to understand the music they sample through an often vague, intuitive representation, which fuses qualities of those recordings with an intersubjective mood, a …

Possibilities Of Being: Black Women's Storytelling As Archival Undoing, Dasharah Green

Dissertations, Theses, and Capstone Projects

This dissertation constructs a discursive genealogy of Black women’s storytelling, positioning its art and aesthetics as a form of colonial archival undoing. Each chapter explores how transmission and documentation can transform—and circumvent—traditional colonial archives. Beginning at the start of the twentieth-century to present, this project traces the discursive legacies of Zora Neale Hurston, Audre Lorde, Michelle Cliff, and Staceyann Chin, examining each writer as a site of becoming as they individually (and collectively) seek to articulate an expansive idea of a Black world that constitutes a broader understanding of Black freedom. They each share a common goal of creating a …

Sec-Saxs And Sans Analyses Of The Talin•Vinculin Complex, Gilbert Reyes

Dissertations, Theses, and Capstone Projects

Focal adhesions (FA) are integrin-based cell-matrix adhesion sites composed of adaptor proteins that facilitate the generation of traction forces important for biological functions such as cell migration, embryo development, wound healing, tissue organization and stability, and immune responses. Mature FA are observed when both autoinhibited multi-domain scaffolding protein talin and membrane-cytoskeletal protein vinculin are activated and interact thus promoting the assembly and function of FA. While research has resolved truncated sections of autoinhibited talin and recruitment of vinculin due to mechanotransduction that exposes cryptic vinculin binding sites (VBS), little is known about the global modifications of full length talin in …

Dancing In Circles: Bon Dance As Performance Of The Past, Travis Robb Kim

Dissertations, Theses, and Capstone Projects

This capstone project traces the contours of the Japanese folk dance tradition of Bon Dance in Hawaiʻi through the nuances of public scholarship, diaspora, and racial capitalism by producing an original play which aims to perform the knowledge and praxis which the performance ritual puts forward. Treating Bon Dance as muse, the original play examines the necessity of turning to the past in order to disrupt a future made inevitable by oppressive systems; a fiction that comments on and critiques the predictive and generative technologies that have embedded themselves into society at large. Through intertwining conversations that explore prophecy and …

Modeling And Generating Trustworthy Speech, Yuwen Yu

Dissertations, Theses, and Capstone Projects

As virtual agents become increasingly integrated into everyday communication, trust has become essential for effective human-AI interaction. Although recent advances in natural language generation and speech synthesis have significantly improved fluency and intelligibility, most systems are not designed to control how trustworthy they are perceived. As a result, a mismatch can emerge between perceived trustworthiness and actual system capability, leading to over-trust or under-trust. While trust is critical for meaningful interaction, current text-to-speech (TTS) systems are primarily optimized for naturalness and intelligibility rather than calibrated trustworthiness.

This dissertation investigates the perceptual foundations of trust in both human and synthesized speech …

Potential Energy Landscape Formalism For Quantum Liquids, Yang Zhou

Dissertations, Theses, and Capstone Projects

Atomic delocalization due to nuclear quantum effects (NQE) remains poorly understood in low-temperature liquids near the glass state and during vitrification. Many liquids can be described accurately by treating their nuclei as classical particles, but this approximation fails for light elements such as He and H₂, small hydrogen-containing molecules such as water, and systems in which zero-point motion or isotope-substitution effects are important. Developing a general thermodynamic and statistical-mechanical description of such liquids has been challenging. This dissertation extends the potential energy landscape (PEL) formalism, originally developed for classical liquids and glasses, to liquids that obey quantum mechanics and exhibit …

The Effects Of Chronic Nicotine Exposure On Dopamine-Mediated Reinforcement Learning And Striatal Neurotransmission, Srishti Bose

Dissertations, Theses, and Capstone Projects

Tobacco is one of the most widely used substances across the United States; tobacco consumption is linked with several diseases and is one of the leading causes of preventable death in the country. Nicotine is the active substrate found in tobacco products, acting as a stimulant, which reinforces continued use. The introduction of tobacco-free options such as e-cigarettes and oral pouches has driven an increase in nicotine exposure across the population, especially in young adults. Acute nicotine use induces neuroadaptations in the mesolimbic dopaminergic system, which mediates reinforcement learning and addiction, that potentiates reward-related neurotransmission. Furthermore, there are clinical studies …

Optimizing Nanoparticle Quality And Function In Applied Research, Angela M. Fried

Dissertations, Theses, and Capstone Projects

Radiology tests are among the fastest-growing categories of diagnostic analysis, and the gold standard of radiology tests is MRI.  MRI can be more informative if a contrast agent is used, and the standard of care contrasting agents (CA) are gadolinium-based.  Gadolinium is a heavy metal, toxic, and contraindicated for renal-compromised patients and the critically ill.  We propose a nanogel (NG) vehicle for an alternative organic CA.  CNs like 4-hydroxy-2,2,6,6-tetramethylpiperidin-1-oxyl (TEMPOL) and its derivatives have a variety of medical and industrial uses.  These cyclic CNs are stable, synthetic radicals with distinctive EPR/ESR signals and are helpful for various experimental applications, from …

Analyzing Harmony In Bulgarian And Bulgarian-Influenced Choral Arrangements From The Radio To The Screen, Annie Beliveau

Dissertations, Theses, and Capstone Projects

This dissertation investigates developments in arrangements and compositions made for Bulgarian choirs between 1950 and 2025. Arrangements from Bulgaria’s communist period (1944-1989), when musical radio broadcasts were tailored to promote nationalist sentiment, eventually reached the ears of foreigners on the other side of the Iron Curtain via recordings and ensemble tours. These obrabotki (arrangements of folk tunes) became popular in the “world music” boom of the 1980s, and foreign composers soon began to create new compositions for Bulgarian choirs to sing on albums and in scores for film, television, and video games. Over time, the uses of Bulgarian choir in …

Mapping The Water Quality Of Jamaica Bay, New York (1996-2024): Principal Component Analysis And K-Means Clustering, Sneha Srivastava

Dissertations, Theses, and Capstone Projects

Jamaica Bay, located along the southeastern coast of New York City, acts as a biodiverse estuary of wetlands, meadows, and salt marsh islands. The purpose of this study is to analyze the water quality conditions of the region over time, comparing locations around the bay to identify hyperlocal features that influence larger trends in the hydrological system. Ten variables were used as water quality indicators, including total Kjeldahl nitrogen, salinity, pH, Secchi disk depth, and total phosphorus, among others, across five stations in the bay, between 1994 and 2024. After data cleaning and standardization methods were applied, principal component analysis …

Panopticism And Pan-Oticism: Sound-Power From Foucault To Deleuze, Eric Dillenberger

Dissertations, Theses, and Capstone Projects

From Muzak to long range acoustic devices (LRADs), the contemporary proliferation of sonic technologies for governing moods, behaviors, and potentialities complicates the virtual absence of sound within Michel Foucault's primarily visual modality of disciplinary power in Discipline and Punish, exemplified by his central conceptual model of the panopticon. This thesis develops the corollary concept of pan-oticism to theorize the transformation of sound-power and its political function within administered sonic ecologies from Foucault's disciplinary societies to Gilles Deleuze's societies of control. Within the enclosed spaces constitutive of disciplinary societies, sound-power remains subordinated to Foucault's visual logic of panopticism, extending …

Rethinking Road Racing Standards: Comparing New York Road Runners Race Results To Running Industry Standards, Jennie Coughlin

Dissertations, Theses, and Capstone Projects

Running has undergone a third boom in participation since 2020, driven largely by people seeking fitness options that were outside and socially distanced during the COVID-19 pandemic. Social media has also allowed runners from groups that did not traditionally participate to find community. As the road racing population has expanded to include more people, some road racing industry standards have not kept up. This project assesses what the road racing community looks like and measures industry standards against the community of participants to see what changes in those standards would be needed to make them inclusive for all participants.

Individual Intellectual Humility As A Predictor Of Perceived Information Sharing And Perceived Shared Leadership, Mary Beth Schroeder

Dissertations, Theses, and Capstone Projects

Cross-functional problem-solving teams are often assembled to address complex challenges by combining members’ distinct knowledge, ideas, and leadership capabilities. Yet teams do not always capitalize on these collective resources, because team members do not share the information they uniquely possess. This tendency to withhold information may be lessened by intellectually humility, a personality trait marked by a desire to close gaps in one’s knowledge and openness to what others contribute.

This study was originally designed to examine whether team intellectual humility relates to team creativity through information sharing and shared leadership. However, because of changes in the leadership development program …

Investigating The Role Of Striatal Cholinergic Interneuron D2 Receptors In Behavioral Flexibility, Janyn J. Alfred

Dissertations, Theses, and Capstone Projects

Dopamine (DA) and acetylcholine (ACh) interact within the striatum to shape reward-based learning and choice behavior. DA D2 receptors on cholinergic interneurons (CIN D2Rs) were genetically knocked out to investigate their role in choice allocation using a two-lever matching paradigm. Behaviorally, both knockout (KO) and wild-type (WT) mice learned the initial task equally well. When shifted to asymmetric matching schedules (VI-90 vs. VI-180), ideal matching predicts that mice should allocate exactly 67% of their total responses to the rich lever. Neither group matched as predicted by the matching law. Instead, the KO mice showed a pattern where the higher rate …

Urban Counterpoint (1992–2003): The Piano Music Of Ed Bland, Joseph Vaz

Dissertations, Theses, and Capstone Projects

This dissertation analyzes the piano music of Ed Bland, a politically and philosophically vocal composer active in the second half of the twentieth century, whose music draws on both the European and American twentieth-century avant-garde, and on African American vernacular music genres from ragtime to hip-hop. A review of the historical and personal context for these pieces, and a detailed examination of the compositional processes used in this music, work together to demonstrate how Bland thought about the relationship between different musical genres and languages.

Through this combination of theory of musical genre, historical and biographical study, and detailed analysis …

Waltzing Into Silence: Time, Space, And The Afterword In Ravel’S Valses Nobles Et Sentimentales In Comparison With Schumann’S Davidsbündlertänze, Op. 6, Nora I. Bartosik

Dissertations, Theses, and Capstone Projects

This dissertation undertakes an analysis of Maurice Ravel’s Valses nobles et sentimentales for piano against the backdrop of Robert Schumann’s Davidsbündlertänze, Op. 6, a work with significant parallels in structure, character, and narrative. The Davidsbündlertänze are examined as a model for the Valses nobles et sentimentales, with an emphasis on the two works’ use of the waltz form, their structure as a series of miniature dances composed as a single cohesive work, and their inclusion of an afterword, or epilogue. The analysis draws from the extensive literature on Schumann’s piano cycles in order to apply similar techniques to …

Retrieval Information From Working Memory: The Output Gating Framework Perspective And Its Underlying Processes, Chen Tiferet-Dweck

Dissertations, Theses, and Capstone Projects

Working memory (WM) keeps information accessible and available for further processing. However, not all the information we maintain in WM is behaviorally relevant at any given moment. To act effectively, we must dynamically control which memory representations are accessed to support ongoing goal-directed behavior. While the mechanisms underlying the selection of single items from WM access are comparatively well-studied, less is known about the principles governing multi-item access. Existing models of WM access imply that selecting multiple items should take longer and be more error-prone than single-item access. Yet, paradoxically, prior studies have shown that retrieving all items in WM …

The Role Of Temperament In Criminal Trajectories: Development, Stability, And Predictive Power Across The Life Course, Joshua A. Lang

Dissertations, Theses, and Capstone Projects

Temperament, an individual's largely innate tendency to experience and regulate responses to their environment, has long been studied but was only recently introduced as a primary predictor of criminal behavior (DeLisi & Vaughn, 2014). While prior criminological theories have incorporated temperament-related constructs, such as negative affect (Agnew, 1992; Moffitt, 1993) and self-control (Gottfredson & Hirschi, 1990), no other theory has explicitly positioned temperament as the central factor in offending. DeLisi and Vaughn’s temperament-based theory of antisocial behavior posits that individuals with low effortful control and high negative emotionality—features of a difficult temperament—are more likely to engage in criminal behavior. Despite …

The Role Of External Factors In Shaping Carbohydrate Conformational Landscapes, Murat Yaman

Dissertations, Theses, and Capstone Projects

Carbohydrates (glycans) are among the most structurally diverse biomolecules and participate in a wide range of biological processes, including molecular recognition, cell adhesion, immune response, host-pathogen interactions, and cellular signaling. Their biological functions are governed by a complex interplay between sequence, stereochemistry, conformational flexibility, and environmental factors. However, the structural heterogeneity and dynamic nature of glycans present significant challenges for both experimental characterization and theoretical modeling. In particular, the relationships between glycan structure, conformational dynamics, and the resulting potential energy surfaces remain incomplete.

This dissertation investigates how external factors modulate the potential energy surfaces of carbohydrates through a combination of …

Riluzole As A Dual-Targeted Radiosensitizer For Osteosarcoma: Targeting Tumor Cells And Angiogenic Vasculature To Enhance Single High-Dose Radiotherapy Efficacy, Pooja P. Rao

Dissertations, Theses, and Capstone Projects

Osteosarcoma (OS), the most common primary bone malignancy of children and young adults, is intrinsically radioresistant, and outcomes for patients with unresectable or metastatic disease have not improved in over four decades. Single-dose radiation therapy (SDRT) is a potent modality against radioresistant, highly vascularized sarcomas, but its application in OS is constrained by dose-dependent normal tissue toxicity. Radiosensitizers achieving tumor control at lower doses therefore offer a direct route to widening the therapeutic window. Critically, OS radioresistance is not tumor-cell-autonomous. It emerges from two coordinated compartments: aberrant DNA repair and antioxidant capacity intrinsic to the tumor cell, and a radioprotective, …

‘A Sense Of The Sea’: Grassroots Culture, Care, And Endurance In Swansea, Cymru, Katy Clark

Dissertations, Theses, and Capstone Projects

This thesis argues that under present conditions, everyday political-aesthetic life is not only about resistance or reproduction but about holding: the work of keeping people, practices, and attachment present and oriented as conditions change. Holding takes the form of care and maintenance; as practices of making, assembling, and imagining; and as the work that keeps open the possibility of renewed attachment to public things and to each other. In the field, this was named as ‘a sense of the sea’, an affective register characterized by wariness, attunement, attentiveness, orientation, and endurance. I am calling this a fragile infrastructure of …

New York City Women’S Experiences With Perinatal Depression Inquiries, Diagnosis, And Treatment Initiation, Caterina Pisciotta

Dissertations, Theses, and Capstone Projects

Perinatal depression represents a significant public health concern, yet many women who experience depression symptoms during the perinatal period (either during pregnancy and/or after birth) do not receive treatment. Initiatives, such as ThriveNYC, were designed to address these gaps by screening and treating perinatal women for maternal depression, integrating screening into routine perinatal care and strengthening pathways to treatment. Using representative survey data collected between 2016 and 2021 via the Center for Disease Control and Prevention’s Pregnancy Risk Assessment Monitoring System (PRAMS), this study examined trends in perinatal depression inquiries (a proxy for “screening”) and postpartum diagnosis, as well as …

Towards Identifying Fear And Safety Network States Across Sex, Rhonda Kolaric

Dissertations, Theses, and Capstone Projects

Post-traumatic stress disorder (PTSD) is a trauma- and stressor-related disorder with a lifetime prevalence of 5-6% in men, and 10-12% in women (National Center for PTSD). Generalized anxiety disorder (GAD) is a highly prevalent anxiety- and depression-related psychiatric disorder with a lifetime prevalence of 1-2% in men, and 3-4% in women (National Institutes of Health). Both of these disorders disproportionately affect women. A hallmark feature of both disorders is the maladaptive generalization of fear, in which defensive responses extend beyond the original traumatic or threatening stimulus to neutral or unrelated cues. This overgeneralization can become debilitating, disrupting cognitive, emotional, and …

Ultrafast Spectroscopy Of Organic Materials In Strong Light–Matter Interaction And Terahertz Optics, Kamyar Rashidi

Dissertations, Theses, and Capstone Projects

Ultrafast spectroscopy is a powerful tool for investigating phenomena that occur on extremely short timescales and for probing ultrabroadband spectral responses enabled by its ultrashort laser pulses. These capabilities are essential for advancing both the fundamental understanding of light–matter interactions and the development of next-generation optoelectronic technologies. The first part of this thesis investigates the ultrafast dynamics of organic exciton–polaritons and their application to controlling molecular excited-state processes using momentum-resolved pump–probe spectroscopy. A major challenge in these systems is the dark-state problem, where photoexcitation predominantly populates long-lived excitonic reservoir states that obscure the in trinsic dynamics of the hybrid light–matter …

Analysis Of Diterpenoid Alkaloids From American Aconitum Using Lc-Ms Metabolomic Methods, Yi Zhao

Dissertations, Theses, and Capstone Projects

Analysis of Diterpenoid Alkaloids from American Aconitum Using LC-MS Metabolomic Methods

by

Yi Zhao

Advisor: Edward J. Kennelly

Aconitum plants have been used as a traditional medicine in Asian countries for millennia to treat pain, rheumatism, syncope, fever, and other conditions. These therapeutic effects are mainly due to the bioactive diterpenoid alkaloids accumulated in the roots. Comparing with the large records and studies of Asian Aconitum and their medicinal use and the broad bioactive compounds, American Aconitum has been rarely investigated, not to mention how American Aconitum has been used medicinally. Based on previous phylogenetic and chemotaxonomic studies of Aconitum …
