Controlling Emotional Text To Speech Using Complex Adverbial Phrases, Zainab T. Akande

Dissertations, Theses, and Capstone Projects

This study investigates the usage of adverbial modifiers from audiobook data as a resource for training speech synthesizers with a greater range of speech descriptions. The Tacotron2 text-to-speech (TTS) model was used for the purposes of this study. Utilizing the LibriTTS dataset, the Tacotron2 model is trained under two experimental conditions: one incorporating adverbial modifiers into the input text and the other without. The dataset preprocessing involves embedding descriptions using word embeddings and encoding speaker IDs with machine learning techniques. Additionally, the model architecture includes a prosody encoder inspired by prior research. Evaluation of the trained models involves subjective assessments …

Shear Viscosity Of Quasi One-Dimensional Bec Tubes And Entanglement Negativity Conditions, Camilla Polvara

Dissertations, Theses, and Capstone Projects

Shear Viscosity of Quasi One-dimensional BEC Tubes

We consider layered Bose-Einstein condensates interacting via contact intra-condensate interacions and dipolar inter-condensate potentials, both of which dominate intercondensate tunneling (which we neglect for simplicity). For this system, we compute the normal modes, we study its localization properties by numerically computing the inverse participation ratio, and we compute the inter-tube shear viscosity.

Entanglement Negativity Conditions

This project explores bounds on entanglement negativity using operator inequalities, building on the results of [1]. We are looking for a way to quantify entanglement, as an alternative to calculating the full negativity, which would otherwise require the …

Resting-State Eeg Microstate Features For Major Depressive Disorder Classification, George M. V. Quinn

Dissertations, Theses, and Capstone Projects

Neuroimaging studies have revealed consistent abnormalities in functional connectivity within specific neural networks that may serve as biomarkers for major depressive disorder (MDD). It is important to find inexpensive, non-invasive techniques that target these biomarkers to make diagnosis easier and more objective. EEG microstates are quasi-stable potential topographies that are thought to reflect the quasi-stable network activity of the underlying neural generators. MDD has been shown to alter features of the four canonical EEG microstates (A, B, C, D) with some conflicting results. The most consistent network abnormalities in MDD are found in the anterior default mode network, and this …

Singing Petrarch In The Cinquecento: Embodied Reading And The Italian Madrigal, Thomas A. Hedrick Iii

Dissertations, Theses, and Capstone Projects

This dissertation examines how composers of sixteenth-century Italian madrigals highlighted poetic line rhythm, repeated vowel sounds (or assonance), and word repetition in figures of speech—all elements of the verse that have been previously overlooked by scholars, who have traditionally focused on musical depictions of the text’s semantics. The analysis in chapters 2, 3, and 4 shows that composers used a consistent set of techniques from the madrigals of Arcadelt to those of Monteverdi, and musical examples draw from large collection of madrigals on Petrarch sonnets. The analytical methodology is built on the premise that Cinquecento encounters with poetry can be …

String Quartet, Scott A. Miller

Dissertations, Theses, and Capstone Projects

This quartet begins by providing glimpses of three distinct musical ideas. Although they seem totally unrelated, the music seeks to confound this initial expectation. Related textural contrasts are developed between dialogical textures and the quartet speaking as one voice. The pitch material combines just intonation with twelve tone equal temperament.

Newly Synthesized Pyroglutamate Amide And Its Neuroprotective Effect Against Neurotoxicity Induced Cell Death In Alzheimer's Disease, Nourelhouda Joutey Elamrani

Dissertations, Theses, and Capstone Projects

The neurodegenerative disorder is an umbrella term for a range of conditions that affects the neurons in the human brain causing neuronal cell death. The common pathway is the excitotoxicity, a phenomenon that describes the toxic actions of excitatory neurotransmitters, primarily glutamate, where the exacerbated or prolonged activation of glutamate receptors starts a cascade of neurotoxicity leading to the cell death. One of the most common neurodegenerative disorders is Alzheimer’s disease (AD), which represents 60 – 70% of cases and it ranked fourth cause of mortality in the USA. In Alzheimer’s disease, glutamate released from astrocytes and activates extrasynaptic N-methyl-D-aspartate …

Self-Perceived Cognitive Functioning In Motoric Cognitive Risk Syndrome: Enhancing Risk Detection In Health Disparity Older Adults, Caroline O. Nester

Dissertations, Theses, and Capstone Projects

Motoric Cognitive Risk Syndrome (MCR) is a predementia condition that combines two clinical presentations associated with dementia: slow gait speed and subjective cognitive concerns (SCC). MCR diagnosis is associated with increased risk for dementia over its individual components of SCC or slow gait alone, making it a valuable marker of early neurodegenerative changes. MCR does not require expensive, time-consuming assessments to be diagnosed, broadening accessibility in remote or under-resourced settings. At present, there is no consistent method to assess SCC in MCR – a key diagnostic feature of the syndrome. The lack of understanding about SCC in MCR may limit …

A Praxis Of Radical Collectivity: Centering Justice And The Poetics Of Racialized Progressive Leadership, Alisa Algava

Dissertations, Theses, and Capstone Projects

Educational research that effectively addresses larger sociopolitical and sociohistorical contexts must interrogate macro-level decision-making and policies and prioritize the lived experiences of those who directly affect and are affected by social structures. This project explores racial and economic justice work in schools by centering the perspectives of those progressive educational leaders who strive, work and grapple to center all adults and children within our larger unjust education systems. As individual leaders share their stories through one-on-one recollections and in critical collaborative inquiry groups, they illuminate spaces of contestation, continuity and liberation. The context of both continuous and unfolding pandemics along …

Assessing The Influence Of Llms On Online Review: Identifying And Addressing The Rise Of Convincing Fake Reviews, Zico Abhi Dey

Dissertations, Theses, and Capstone Projects

Large Language Models (LLMs) have made remarkable advancements, reaching a level where they can generate outputs that compete with human writing. LLM's sophisticated features, however, make it hard for us to spot the difference between human-written and AI-generated text. LLMs have several weaknesses since they are susceptible to hallucinations and outputting factually incorrect information. Additionally, they may be used maliciously to promote deception and instigate fraud, such as fake reviews generation, which rapidly appear on the internet while posing a challenge for consumers who want to place their faith in online reviews. To maintain trust in the online information system, …

A Multilevel Approach To The Analysis And Visualization Of Timbral Brightness In Post-Tonal Music, Stephen Spencer

Dissertations, Theses, and Capstone Projects

This dissertation develops a method for the analysis and visualization of timbral brightness in post-tonal music. Brightness, a salient timbral attribute correlated with the prominence of high frequencies in the sound spectrum, is crucial for distinguishing sounds and discerning how they fit together in music. The dissertation employs a multilevel analytical approach, measuring differences in brightness at multiple “textural levels” and temporal scales. The analytical utility of the approach is demonstrated through four case studies, each one closely examining the score and audio of a piece of instrumental music written in the first quarter of the twentieth century.

Musical Semiotics In Kate Soper’S Ipsa Dixit (2010–2016), Scott A. Miller

Dissertations, Theses, and Capstone Projects

This dissertation analyzes the six parts of Kate Soper’s Ipsa Dixit (2010–2016). While individual parts have received some music theoretical attention, this is the first analysis of the entire Pulitzer Prize-nominated work. Ambiguity and contingency are major themes of Ipsa Dixit, and by treating each part independently and in combination, I hope to honor Ipsa’s contingent status as a unified work comprised of six complete works. Soper’s libretto unifies an assemblage of texts with adaptations of Aristotle to investigate the intersections of language and music with authority, veracity, and (un)intelligibility.

I theorize that Soper’s “philosophy-opera” dramatizes the formation of …

On Deformation Rings Of Residual Galois Representations With Three Jordan–Hölder Factors, Xiaoyu Huang

Dissertations, Theses, and Capstone Projects

In this paper, we study Fontaine-Laffaille, self-dual deformations of a mod p non-semisimple Galois representation of dimension n with its Jordan–Hölder factors being three mutually non-isomorphic absolutely irreducible representations. We show that under some conditions regarding the orders of certain Selmer groups, the universal deformation ring is a discrete valuation ring. Given enough information on the Hecke algebra, we also prove an R = T theorem in the general context. We then apply our results to abelian surfaces with cyclic rational isogenies and certain 6-dimensional representations arising from automorphic forms congruent to Ikeda lifts. Assuming the Bloch-Kato conjecture, our result …

Lgbtq+ Employees’ Disclosure And Selective Incivility Experiences: Implications For Their Health And Well-Being, Wiston A. Rodriguez

Dissertations, Theses, and Capstone Projects

Workplace incivility refers to low-intensity rude behaviors at work that have an ambiguous intent to harm and also violate workplace norms of mutual respect. Given the negative consequences associated with workplace incivility, researchers have been trying to understand potential antecedents to experienced workplace incivility such as target characteristics or group affiliation. Prior research suggests that uncivil behaviors may not be enacted at random and may manifest in the form of selective incivility (i.e., subtle discrimination). Specifically, selective incivility is a form of targeted mistreatment that is used to oppress and exclude minorities in the workplace and is a unique experience …

Using A Novel Chain Of Chemical, Crystallographic, And Isotopic Analytical Techniques To Examine The Formation Histories Of Features In Chondritic Meteorites And Orbicular Granites, Samuel P. Alpert

Dissertations, Theses, and Capstone Projects

Understanding the chemistry, crystallography, and isotopic variability of minerals allows us to place significant constraints on the formation history of their host rocks. These constraints provide insight into everything from the distribution of water in the solar system to the onset of plate tectonics. Electron beam instruments and ion probes are important tools used by modern geologists to obtain crystallographic, chemical, and isotopic data. Here I present a new workflow, using these instruments, combining wavelength dispersive spectrometry (WDS), backscattered electron (BSE) imaging, machine learning algorithms, electron backscatter diffraction (EBSD), and secondary ion mass spectroscopy (SIMS), to place quantitative constraints on …

Dissertations, Theses, and Capstone Projects

In today's digital world, detecting fake news has emerged as a critical challenge, one that has significant effects on democracy and public discourse at large both regionally and globally. This research studies how diversity of news sources in training datasets affects how well machine learning models can classify fake vs true news. I used the Linear Support Vector Classification (LinearSVC) to create and compare two classification models: one was trained on a dataset that only had real news from a singular source, Reuters (Dataset 1), and the other was trained on a dataset that contained real news from Reuters, The …

What The Debate About Spanish Gender-Inclusive Forms Reveals Regarding Ideological Beliefs About Language And Authority, Jalitza Gutierrez

Dissertations, Theses, and Capstone Projects

The “masculine generic” is a feature of Spanish that dictates that the masculine ending, (-o), is generally used as the default when referring to a mixed-sex group or when the sex of a person or group is unknown. Critics have claimed that this linguistic feature is sexist and contributes to the invisibility of women and gender-nonconforming people within the language (Eisenberg, 1985). In order to combat these issues, critics have campaigned for the revision of Spanish to include gender-inclusive language, which has continued to be a source of debate, both from the bottom-up and from institutions such as the Real …

Examining The Factors That Contribute To The Survival And Resilience Of The Al-Shabaab Terrorist Organization, Kevisha R. Kellar

Dissertations, Theses, and Capstone Projects

This thesis explores the enduring threat posed by Al-Shabaab in Somalia, examining three primary factors contributing to its resilience: the mismanagement of international intervention, inadequate government oversight and resources, and Al-Shabaab’s ability to adapt to Somalia’s socio-political environment. These factors help Al-Shabaab foster direct and indirect relationships that allow the organization to survive. Through an analysis of Al-Shabaab’s organizational structure and strategies, this study sheds light on the exploitation of political, economic, and religious dynamics, and the complexity of combatting Al-Shabaab. Al-Shabaab’s manipulation of an Islamic identity is a political tool, that fosters business networks, aids in arms acquisitions, evades …

The Role Of Language Ideologies In Curriculum Design: Possibilities In Computational And Digital Literacies Integration In Teacher Education, Jessica Velez Tello

Dissertations, Theses, and Capstone Projects

Literacy and language are linked in its usage, perception, and practice. As new forms of engaging with literacy are explored, digital practices and tools are being employed as useful supports for students and their language practices (García et al., 2017). As emerging technologies are further introduced in educational spaces, education programs have a role in shaping how computational and digital literacies (CDLs) are integrated and how teacher candidates and teachers learn about them, especially those who are being trained to become bilingual teachers or will inevitably work with emergent bilinguals and linguistically diverse learners^[1], as the intersections between …

Uses Of The Intuition: The Role Of Intuition In Birth Work (Towards An Intuitive Epistemology), Kayla R. Reece

Dissertations, Theses, and Capstone Projects

Intuitive knowledge ought to be esteemed, practiced, and integrated alongside traditional forms of knowledge. The coloniality of knowledge has structured our society’s ways of thinking to suppress knowledges which reside in non-hegemonic formations and sources, such as our bodies and intuitions. This paper assesses the uses of the intuition as potential sites of an intuitive epistemology through the author’s experience as an intuitive tarot card reader and through the experiences of six BIPOC birth workers living and working in the United States. I conceptualize the intuition as embodied, relational, and predictive, which offers a framework that privileges information one can …

Placemaking And Placewashing In Manhattan's Chinatown: Capitalist Vs. Community Interests, Mary Chu

Dissertations, Theses, and Capstone Projects

Since the late 1890s, there have been internal and external placemakers in Manhattan’s Chinatown. They take the form of city government, real estate developers, and community organizations vying for space, and seeking to define what this neighborhood should be, for whom it should serve, and how it should look. Sometimes these would-be placemakers operate with neoliberal goals and overt orientalist and/or racist views. They push those narratives through via media representations and as a tactic to attract tourism, but with little regard for how it affects the community. In this work, I examine connections between historic ideas of placemaking and …

Analysis Of Victim/Villain Narratives Presented Under Genocide And Ethnic Cleansing Frameworks: The Kosovo Case, Kristi Allaj

Dissertations, Theses, and Capstone Projects

The small country of Kosovo has been a point of contestation in the Western Balkans for decades. In that regard, the country has divided the two main feuding groups into Albanians and Serbians, who contemporarily showcase intense ethnic rivalries. The 1998-1999 conflict impacted the region's demographics, the international community's normative changes, and the contemporary policies of the now-independent country. The Kosovo War is often attributed to ethnic tensions and the rise of nationalism. At the same time, the NATO intervention that created a series of dissenting opinions is pinned on the humanitarian crisis. All notions that stand. This thesis aims …

What Does It Mean To Be Kindergarten "Ready?": Trends In Parents' Expectations And Families' School Experiences Across Ses, Lisa Babel

Dissertations, Theses, and Capstone Projects

The purpose of this study is to explore the meaning of Kindergarten “ready,” especially as the practice interacts with educational inequity. Past research used secondary data to show that SES relates to the prevalence of redshirting where children’s school entry is delayed by one year with the idea that the older they are when they start school, the more advanced they will be, but studies do not explain why children from families with lower incomes are advised to start Kindergarten later than others (Greensburg & Winsler, 2020; Reardon & Portilla, 2016). Moreover, family expectations of the Kindergarten participation process, including …

Effect Of Magnetic Draping On Satellite Galaxies In Clusters, Vanessa Brown

Dissertations, Theses, and Capstone Projects

Galaxy evolution has been observed to be influenced by environment. Satellite galaxies orbiting within clusters can experience changes in morphology and composition through various mechanisms such as ram-pressure stripping (RPS), which removes a galaxy’s interstellar medium as it passes through the cluster via direct interaction with the hot intracluster medium gas. An open question is whether intracluster magnetic fields affect galaxy evolution, for example by forming a magnetic layer around infalling galaxies (called magnetic draping) and mitigating gas removal by RPS. Using the code GADGET-3, we compare global properties and mass distributions within identical cluster simulations run with and without …

In addition to its novel collection methods, MapLemon contains …

Development And Application Of Magnus Expansion Based Propagators For Problems In Spectroscopy And Quantum Dynamics, Taner M. Ture

Dissertations, Theses, and Capstone Projects

Stable and accurate numerical propagators of time-evolution equations in quantum mechanics are required to capture correct dynamical behavior, especially in the long time limit. Magnus expansion (ME) provides a general way to expand the real time propagator of a time dependent Hamiltonian within the exponential such that the unitarity is satisfied at any order. Integrators are developed by truncating the ME and using explicit integration of Lagrange interpolation formulas for the time dependent Hamiltonian within each time interval. The derived approximations are studied in a numerical test and compared to other available expressions. The sixth order expression is applied to …

The Impact Of Playing As A Non-Stereotypical Woman In A Role-Playing Video Game On Players’ Real World Gender Role Attitudes, Hunter Kincaid

Dissertations, Theses, and Capstone Projects

This study had participants play the modern role-playing video game Skyrim as a female character with one of three different body types: an idealized feminine body typically found in video games, a tall muscular body that more realistically represents a warrior woman, and a lizard body that is hard to gender stereotype using human gender role attitudes. Participants were given a pretest and posttest measure that checked their gender role attitudes and were allowed to play the game with no restrictions on the role-play choices they make within the game itself. A lens of Black cyberfeminism was applied to critique …

Mandatory Esg Disclosure And Executive Compensation: Evidence From The Europe Union Non-Financial Reporting Directive, Dana Lacondre Nugent

Dissertations, Theses, and Capstone Projects

The European Parliament passed the Non-Financial Reporting Directive (NFRD) with the intent to “encourage firms to identify and manage ESG risk” and “provide more transparent and relevant information …intended to empower stakeholders” (EU Directive 2014/95/EU). In my dissertation, I examine whether this change in the information environment is associated with a change in discretionary compensation as a result of decision-useful information conveyed in the mandated Environmental, Social, and Governance (ESG) disclosures. While I expected that new ESG information (Resist) would experience cross-setting changes, my results show that the impact of the mandate is more nuanced. I find herein that …
