The Role Of Parent Psychiatric Symptoms In The Intergenerational Continuity Of Child Neglect: A Prospective Examination, Cody D. Stitzel

Dissertations, Theses, and Capstone Projects

Parental history of childhood neglect is a risk factor for offspring neglect. When a parent and their offspring both experience neglect in childhood, the phenomenon is referred to as the intergenerational continuity of child neglect. Understanding how child neglect is continued from one generation to the next is essential for creating effective interventions and prevention strategies that may help break the cycle. Since links between childhood neglect and heightened risk for various psychiatric symptoms have consistently been identified in research, as well as links between various psychiatric symptoms and heightened risk for child neglect, it may be that parents’ psychiatric …

Wavelength And Luminance Interaction On Spatio-Temporal Contrast Sensitivity Function, Taylan S. Ergun

Dissertations, Theses, and Capstone Projects

Contrast sensitivity (CS) measures the ability to discriminate objects from their backgrounds under varying conditions(Campbell & Robson, 1968). Contrast sensitivity is important for navigating the real world and operating under different light conditions. The contrast sensitivity function (CSF) reflects how the visual system performs under different conditions. This measure is crucial in assessing the health of the visual system (Chen & Gardner, 2021). CSF contributes to a deeper understanding of how the visual system processes and integrates properties of light to create visual sensation and perception. Human contrast sensitivity depends on the viewing conditions such as field size, luminance, color, …

Britten’S Violin Concerto And His Early Period—Score Analysis And Pacifist Narrative, Magdalena Filipczak

Dissertations, Theses, and Capstone Projects

This dissertation presents a comprehensive study of Benjamin Britten’s Violin Concerto, Op. 15, using the work as a lens through which to examine the composer’s early period. Rather than treating the concerto as a purely technical or stylistic artifact, the study situates it within the broader context of Britten’s formative years, his early artistic circles, the political tensions of the 1930s, and his evolving pacifist stance.

The final third of the dissertation offers a detailed formal and interpretative analysis of the full orchestral score, tracing an expressive arc across the entire work by identifying an idée fixe motif and following …

Refining Orbits And Revealing Origins: A Study Of Giant Exoplanets Around Low-Mass Stars, Angeli Sandoval

Dissertations, Theses, and Capstone Projects

The study of gas giants around low-mass stars offers important insight into planet formation. Core accretion models predict that these planets should have a low likelihood of forming due to the limited disk masses of their host low-mass stars. However, NASA space missions such as Kepler and TESS have revealed an emerging population of Saturn- and Jupiter-like planets around M-dwarfs (referred to as giant exoplanets orbiting M-dwarfs or GEMS) that challenge these expectations. This thesis investigates the detection, confirmation, and analysis of GEMS through pipeline development and a detailed analysis of two systems.

In Chapter 1, I provide background information …

Developments In The Lithographic Engineering Of Bi2sr2cacu2o8+Delta Mesa Terahertz-Emitting Devices, Sarah Elghazoly

Dissertations, Theses, and Capstone Projects

Devices microfabricated from the high-temperature superconducting cuprate Bi₂Sr₂CaCu₂O_8+𝛿 (Bi-2212) are a promising source of coherent terahertz radiation within the ’terahertz gap’ (0.3- 1.5 THz). A current-biased mesa patterned into the surface of a single crystal will produce electromagnetic radiation in the terahertz regime due to the naturally occurring Josephson junctions formed by the stacks of superconducting cuprate oxide planes in the material separated by insulating BiO and SrO barrier layers. Previous research has shown that by fabricating these mesas such that the geometry supports resonant cavity Fabry-Perot modes, the junctions within the mesa …

The Role Of Water In Peptide Behavior And Peptide-Based Water-Responsive Crystals, Janel Jannette Rivera Cancel

Dissertations, Theses, and Capstone Projects

Water plays a crucial role in shaping the behavior and function of biomolecules across the liquid, supercooled, and glassy states. This thesis presents a dual approach combining computational simulations and experimental investigations to explore the influence of water on biomolecular systems, particularly peptide-based materials. We employ molecular dynamics simulations to study the hydration-dependent structural dynamics of homopolymer peptides. Simulations were carried out across a range of temperatures and pressures to analyze changes in hydration and structural stability, shedding light on the behavior of peptides under supercooled and glassy conditions. These studies are especially relevant for understanding biomolecular stability in cryopreservation. …

Liberated Learning Spaces: A Visual Playlist, Tarilyn R. Little

Dissertations, Theses, and Capstone Projects

Liberation can be defined as “the act of setting free” or “being free from limits on thoughts and behavior.” Both an action and a state of being, liberation has long been centered as a key function of education, particularly for those who live in historically and systemically marginalized identities. Despite the long-standing existence of liberation-focused pedagogies and activism aimed at transforming schools and students’ lived experiences, educational institutions in the United States have struggled to live out these ideals, often sustaining and replicating systems and practices of oppression. Drawing on historical and contemporary conversations in education and psychology, Liberated Learning …

Crisis Narratives And The Vicissitudes Of Haitian Foodways: A Critical Comparison Of Three Food Items, Marc S. Gabriel

Dissertations, Theses, and Capstone Projects

Polities and media external to Haiti direct a lot of narrative focus on the country being the source of its own protracted crises. This represents a powerful narrative hegemony that casts the post-colonial nation as a zone of perpetual disasters or crisis. To maintain that narrative domination over Haiti, opportunistic observers of Haiti’s media spectacles of crisis only need to atomize the country’s newest crisis or natural disaster from the history that situates it. The elision of the Haitian memory – a memory of structural adjustment programs, systematic displacement, foreign-sponsored paramilitary violence, erosion of peasant foodways and agriculture – from …

Reinforcement Learning Based Resource Management In Edge Systems, Motahare Mounesan

Dissertations, Theses, and Capstone Projects

Modern end-user applications that are highly compute- and data-intensive, while being extremely latency- and accuracy-sensitive, are increasingly reliant on distributed computing. This paradigm spans a range of architectures, from cloud computing to in-device processing. Cloud computing, though scalable, often incurs high latency and cost, constraints that are particularly problematic for time-sensitive applications. In contrast, in-device computing on end or IoT devices is limited by resource constraints, making it inadequate for many complex workloads. Edge computing presents a compelling alternative by bringing computation closer to data sources, thereby reducing end-to-end latency and improving responsiveness. However, the inherent decentralized and dynamic nature …

Structural Characterization Of A Tarantula Toxin And Its Interactions With Lipid Bilayers And Voltage-Gated Sodium Channels, Krishnakoli Adhikary

Dissertations, Theses, and Capstone Projects

Voltage-gated ion channels are membrane protein complexes. They allow the selective flow of their respective ions down an electrochemical gradient through a central ion conduction pore surrounded by four voltage-sensing domains (VSDs). Various neurological and cardiovascular diseases are caused by mutations in voltage-gated ion channels (VGICs). One of the biggest challenges today is addiction to opioid medication. Coming up with non-opioid drug leads can be a real blessing for society. This is where voltage-gated sodium channel research comes in. Na_v1.7, Na_v1.8, and Na_v1.9 are responsible for pain sensations. Loss or gain of function in …

Satellite-Host Galaxy Co-Evolution With Next-Generation Regulator Models, Austen Gabrielpillai

Dissertations, Theses, and Capstone Projects

The evolution of satellites galaxies is an unsolved problem in galaxy formation. Recent observations such as the SAGA and ELVES surveys find tension in HI contents and star formation of satellites around their central host galaxies when compared to our own local environment, the Milky Way. These processes are potentially highly influenced by the host's circumgalactic medium (CGM), and to constrain these cases requires accurate and fast modeling of satellites-host interactions. In this work, we present our methodology for evolving z = 0 surviving satellites alongside their central galaxy in sapphire, a CGM regulator co-evolution model of galaxy formation. …

The Crisis Of Safety, Well-Being, And Belonging Facing Lgbtq Children: Mad/Crip Of Color Critique Towards A Curriculum Of Radical Care, Jameson Goetz

Dissertations, Theses, and Capstone Projects

In this thesis, I turn toward the study of educational experience, defined broadly to include lived experiences both within and outside of formal schooling institutions. I approach curriculum as an ongoing project of self-understanding in which one becomes mobilized for engaged pedagogical action alongside others in the pursuit social justice. I am guided by the following question, foundational to the field of curriculum studies: for those of us who work alongside LGBTQ children, what knowledge is of most worth? Critically reflecting on ways of working alongside LGBTQ children in the pursuit of social justice, I formulate a mad/crip of color …

Non-Perturbative Aspects Of Gauge Theories Through A Complex Parametrization, Antonina Maj

Dissertations, Theses, and Capstone Projects

This dissertation explores a complex matrix parametrization of four-dimensional non-Abelian gauge theories as a means of gaining analytical insights into (3+1)-dimensional QCD. The low-energy scale of non-Abelian gauge theories remains an elusive area of research even after decades of work. A key challenge lies in identifying physical, gauge-invariant degrees of freedom that are relevant to non-perturbative phenomena. In this dissertation we develop a complex parametrization of gauge fields on which gauge transformations act homogeneously, thereby enabling a manifestly gauge-invariant analytical formulation of the theory.

Chapter one constructs the complex gauge-invariant parametrization for gauge theories living on both complex projective space …

Interspecies Responsivity In Early Modern Drama And Animal Performances, Taylor C. Culbert

Dissertations, Theses, and Capstone Projects

This dissertation proposes an expansive, interspecies definition of performance that uses behavior rather than cognition as the decisive feature and illustrates how such a definition can reshape our approach to theatre and performance history. Using the concept of responsivity, which refers to the embodied and affective ways that humans and non-human animals acknowledge and react to one another, I trace human–animal interactions across a variety of sixteenth- and seventeenth-century performance genres, from the aristocratic stag hunt and entertainments involving trained animals to the plays of Molière and Shakespeare. Drawing on my experience training animals, I offer a new perspective on …

Gestoras Económicas: Dote, Consumo Y Ahorro En La Ficción Latinoamericana (1872–1905), Laura Herrera Liendo

Dissertations, Theses, and Capstone Projects

My doctoral dissertation examines novels published between the decades of 1870 and 1900 by women writers of Peru, Mexico, and Argentina, and analyzes the portrayals of money and economic behavior through their female characters. I investigate how some economic aspects of nineteenth-century capitalism are mobilized to challenge the figure of the angel of the house. By studying novels written by Carolina Freyre de Jaimes (1844-1916) and Mercedes Cabello de Carbonera (1845-1909) from Peru; Juana Manuela Gorriti (1818-1892) and Emma de la Barra (1861-1947) from Argentina; and Laura Méndez de Cuenca (1853-1928) and Refugio Barragán de Toscano (1843-1916) from Mexico, I …

Investigation Of Motor Neuronal And Circuit Level Mechanistic Determinants Of Spinal Excitability Following Cst Injury, Thelma Bethea

Dissertations, Theses, and Capstone Projects

The corticospinal tract (CST) is the primary descending motor pathway in mammals, essential for precise, dexterous movements, especially in humans and nonhuman primates. Damage to the CST, such as from spinal cord injury (SCI), impairs skilled motor function and triggers maladaptive changes including aberrant proprioceptive afferent sprouting and increased spinal excitability. These changes are closely linked to both muscle weakness and the development of hyperreflexia, compounding the functional deficits. Animal models of SCI are valuable for investigating mechanisms of injury and recovery, though traditional models often limit the ability to isolate circuit-specific contributions. To address this, I employed selective unilateral …

The Georgian Of Heritage Speaker Children, Cass Lowry

Dissertations, Theses, and Capstone Projects

This dissertation presents three research articles united in the goal of describing the Georgian language as it is spoken by heritage speakers in the Brooklyn diaspora. The Georgian heritage speaker subjects recruited for these studies were children due to immigration patterns at the time when experimental data was collected. Their production of morphosyntactic inflection and pronouns is compared to adult and child homeland speakers.

Heritage speakers of Georgian demonstrate the following divergences from homeland and standard language comparisons. Nominal case inflection is most affected in heritage production, as heritage speakers use a default case or collapse Georgian's split-ergative and inverse …

Quantum Entanglement Correlations In The Proton On The Light-Front, Eric Kolbusz

Dissertations, Theses, and Capstone Projects

In this work we gather results on information theory applied to proton tomography. We start by analyzing the quantum entanglement of momentum, spin-flavor, and color degrees of freedom (d.o.f.) in the leading valence-quark state of the proton on the light front using standard information theoretical tools, leveraging model wavefunctions by Brodsky and Schlumpf to obtain numerical predictions. Light-cone perturbation theory allows us to introduce the one-gluon correction in the sub-leading Fock state and study the entanglement of the gluonic d.o.f. We find weak entanglement in the spatial d.o.f. of the valence quarks, and significantly stronger entanglement in the analogous d.o.f. …

The Evolution And Reproduction Of Andean Miconia (Melastomataceae), Juan Angulo

Dissertations, Theses, and Capstone Projects

Understanding the factors that shape diversification and distribution in tropical plant lineages is central to explaining the origins of Neotropical biodiversity. Assessing evolutionary history with trait evolution and climatic niche dynamics provides key insights into the drivers of diversification and biogeography, while natural history data remains critical for these evolutionary studies. The Tropical Andes, with its exceptional biodiversity and environmental heterogeneity, offers an ideal setting to explore these processes. In this dissertation, I investigate how reproductive systems, climatic niche dynamics, and pollination strategies influence the evolution and biogeography of Miconia III, a large and ecologically diverse clade in the …

Understanding Why Individuals Maltreated As Children Do Not Retrospectively Self-Report, Kristin S. Lynch

Dissertations, Theses, and Capstone Projects

Individuals with documented histories of childhood maltreatment who do not retrospectively self-report these childhood experiences demonstrate better emotional and psychological outcomes in adulthood. Understanding why these individuals do not retrospectively self-report is important for the development of effective interventions focused on mitigating the long-term consequences of maltreatment. The current study compared maltreated individuals who did not retrospectively self-report (O-R group) to those who did retrospectively self-report (O+R group) to examine theoretical explanations related to intentional nondisclosure (i.e., social desirability and discomfort during the interview) and memory processes (i.e. infantile amnesia, use of mental health services, avoidant coping …

From Sequence To Allostery: How Amino Acid Differences Rewire Coupled Conformational Heterogeneity In The Ptp Enzyme Family, Shivani Sharma

Dissertations, Theses, and Capstone Projects

Protein Tyrosine Phosphatases (PTPs) are critical regulators of cellular signaling, and their activity is often modulated through allosteric mechanisms. Allostery is defined as a chemical or conformational change in one site of the protein due to a binding event at another site. Although several studies have investigated aspects of allostery in PTPs, the mechanistic foundations underlying allosteric regulation remain poorly understood. Despite a highly conserved catalytic domain across PTPs, regions with low or no conservation suggest potential "rewiring" of allosteric networks. This raises key questions about the universality versus individuality of allosteric mechanisms across the PTP family.

In this work, …

Moralists Or Moral Hypocrites? Leveraging Moral Psychology And Social Identity Theory To Increase Support For Reparations Amongst White Americans, Andre Oliver

Dissertations, Theses, and Capstone Projects

The economic gains America made from the enslavement of Africans have long been considered its original sin; indeed, most people living today would agree that such an enterprise was morally depraved. Yet, due to moral opposition, many White Americans reject reparative policies (i.e., reparations) that are developed to remedy the damages done to African Americans by slavery and the subsequent continued discrimination. The present research attempts to address two broad hypotheses across four empirical research studies. The first hypothesis tests whether White Americans' rejection of reparative policies related to slavery and Black discrimination is inherently a moral objection to taboo …

Dissertations, Theses, and Capstone Projects

Mental health emergency response has become a highly scrutinized topic following the Black Lives Matter movement and several notable incidents of mental health emergency service users being killed by police responders. Qualitative interviews were conducted with mental health emergency service users to better understand the experience of using mental health emergency services, garner critical feedback of the service, and explore recommendations to improve future response. A total of 23 participants conducted interviews and detailed 40 incidents of mental health emergency service utilization. These interviews were then coded and analyzed. There were a few major findings from the data. Just over …

Systematics, Biogeography, And Comparative Morphology Of Emerald And Tigertail Dragonflies (Anisoptera: Synthemistidae & Corduliidae), Aaron M. Goodman

Dissertations, Theses, and Capstone Projects

Dragonflies and damselflies (Odonata Fabricius, 1793) are among the most widely recognized and charismatic insect groups, whose significance have permeated throughout artwork, culture, and religion. They are highly mobile predators, currently consisting of ~ 6,500 species, and possessing some of the complex visual color systems, visual acuity, and flight patterns on Earth. Odonata are the among the earliest flying insects, with proto-odonates (Griffinflies) dating back to the Carboniferous (~360mya), with crown-odonata fossils stretching back to the Triassic (~250mya). Overall, dragonflies and damselflies are considered models of ecological and evolutionary research due to their long evolutionary history, range of habitats, and …

Potential Role Of A Ruthenium-Based Compound Ru-Im In The Treatment Of Triple Negative Breast Cancer, Rachele Rameau

Dissertations, Theses, and Capstone Projects

Triple negative breast cancer (TNBC) is an aggressive and heterogeneous molecular subtype of breast cancer that has limited available treatments. The organometallic cationic ruthenium derivative Ru-IM was found to be highly water soluble, was differentially toxic for breast cancer cells and tumors, and was involved in the pI3K/AKT/mTOR pathway. However, a full understanding of genetic and epigenetic factors that can be part of regulatory mechanisms of Ru-IM is yet to be determined. Epigenetic assays including DNA methylation, histone acetylation and histone deacetylation were performed with the half inhibitory concentration (IC50) values of Ru-IM. Bisulfite sequencing of untreated and treated MDA-MB-231 …

Interoceptive Forecasting And Recall: The Role Of Anxiety Sensitivity And Disgust Sensitivity, David Lloyd Yap

Dissertations, Theses, and Capstone Projects

Predicting and remembering emotional states (affective forecasting and recall) are adaptive processes that allow individuals to engage with the future and past to guide behavior, yet these processes are prone to bias. Although affective forecasting and recall biases are common across healthy populations, more pessimistically biased affective forecasts and recall have been linked to greater anxiety and depression symptom levels and to emotional disorders. A crucially understudied aspect of affective forecasting and recall is the perception of the somatic (interoceptive) symptoms that accompany emotions. This study investigated forecasting and recall accuracy of somatic symptom levels (i.e., interoceptive forecasting and recall). …

Collaborative Memory And Metamemory: The Impact Of Normative And Informational Motivations On Conformity, Karen Rodriguez

Dissertations, Theses, and Capstone Projects

Collaborative memory studies have typically explored the cognitive mechanisms that underlie differences between collaborative and individual memory performance. Despite the social nature of collaboration, few studies have examined the impact of social motivations on collaborative memory. When retrieving information with groups, people may not only be motivated by a desire to be accurate (i.e., informational motivations), but may also be guided by social norms (i.e., normative motivations), such as prioritizing agreeability or alignment with group members (Cialdini & Goldstein, 2004). Similarly, retrieving information with others may also prompt individuals to reflect more on their own memory processes. However, few studies …

Enjoyment In The Classroom: Reciprocal Student-Teacher Dynamics In Israeli Math Education, Yonaton Gutterman

Dissertations, Theses, and Capstone Projects

Enjoyment is increasingly recognised as a keystone emotion in contemporary models of academic motivation and learning (Pekrun, 2006; Ryan & Deci, 2020). Grounded in Control-Value, Expectancy-Value, and Self-Determination theories, the present study tracked reciprocal affective processes in Israeli mathematics classrooms across ten lessons. Seven teachers and their 257 students (112 fourth-graders; 145 eighth-graders) completed parallel post-lesson questionnaires assessing feedback use, enjoyment, and perceived difficulty. Multilevel ordinal mixed-effects models, latent-growth curve models, and Bayesian random-intercept cross-lagged panel models were estimated to disentangle within-person fluctuations from between-person differences (Hamaker et al., 2015). Confirmatory-factor analyses supported scalar invariance of the key scales over …

Using Machine Learning Methods To Evaluate Undergraduates’ Executive Function In The Context Of Game-Based Measurement, Ming Chen

Dissertations, Theses, and Capstone Projects

Traditional performance-based measurements have faced criticism due to their potential to induce test fatigue and their limited ecological validity. In contrast, game-based assessments have demonstrated the capacity to engage participants effectively in tests and enhance ecological validity by replicating real-world scenarios. Nevertheless, conventional statistical approaches may prove insufficient in capturing the intricate, non-linear associations between participants' gaming performance and their cognitive capabilities. Leveraging the potential of machine learning (ML) techniques, which can model complex problems, offers a promising avenue for estimating students' performance in video games. This dissertation aims to explore various ML methods for the validation of three game-based …
