Behavioral Biomarkers Of Vulnerability In The Aba Model, Nora Ozer

Dissertations, Theses, and Capstone Projects

Anorexia nervosa (AN) is a severe psychiatric disorder with the highest mortality rate among mental health conditions, yet effective biological treatments remain limited. The activity-based anorexia (ABA) paradigm, which combines food restriction with wheel access to model the hyperactivity and self-starvation cycle characteristic of AN, shows considerable individual variability in vulnerability. Understanding what predisposes certain individuals to develop the full ABA phenotype while others remain resilient could inform early intervention strategies for human AN. This study employed continuous behavioral monitoring technology to identify early predictors of vulnerability to activity-based anorexia in mice, with the goal of discovering behavioral biomarkers that …

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 …

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 …

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 …

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 …

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 …

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. …

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 …

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. …

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 …

Machine Learning And Crime Prevention, Emily Lizewski

Student Theses

Predictive policing uses machine learning to analyze crime patterns and help law enforcement better efficient use their resources. These tools can improve accuracy by highlighting complex trends in large sets of data. While this technology has its advantages, it also raises important ethical and social questions. Within this paper we looks at how predictive policing works, focusing on the machine learning models often used such as decision trees, random forests, gradient boosting, and models that factor in both time and location. It also explores how these tools might unintentionally reinforce biases already present in historical crime data. In reviewing the …

Disentangling The Effect Of Criminal Legal System Involvement On Mental Health In The United States, Pui Ying Chan

Dissertations and Theses

BACKGROUND: Interactions with the criminal legal system (CLS), such as through arrest or incarceration, are relatively common in the United States (US) and are increasingly recognized as social risk factors for poor mental health. Previous studies have reported a positive association between CLS involvement and poor mental health, with some theoretical frameworks, including the ecosocial theory and the stress process paradigm, supporting a plausible causal relationship. However, prior research has significant limitations in providing casual evidence given possible reverse causation in cross-sectional studies and insufficient consideration for the dynamics between CLS exposures, mental health status, and related confounders over time …

Advanced Robotic Multimodal Imaging With Real-Time Motion Compensation For Dynamic Structural Health Monitoring, George Papaioannou, Christos Mitrogiannis, Mark Schweitzer, Maria Pappa, Pegah Khosravi, Apostolos Karantanas, Chris Ruberg, Shawn Owens, Nikolaos Michailidis

Publications and Research

Modern composite materials promise superior performance and load-bearing capabilities, yet evaluating their structural integrity remains challenging. Current testing methods, such as visual, thermographic, ultrasonic, optical, electromagnetic, terahertz, shearography, X-ray, and neutron imaging, are hampered by long scan durations, limited field of view, suboptimal accuracy, and high costs, particularly when applied to large structures.

This paper addresses these issues by introducing a novel robotic multimodal imaging system that overcomes the limitations of traditional methods. This system dynamically captures both static and dynamic properties of materials using advanced motion compensation techniques. By integrating multiple radiographic modalities into a coordinated robotic platform, it …

Investigating Relationships Between Education Professionals' Trauma Histories And Causal Attributions For Students' Disruptive Behaviors, Christina D. Rodefeld

Theses and Dissertations

Using attribution theory as a theoretical framework, this mixed methods study investigated how education professionals reported and perceived the relationship between their histories of trauma and their attributions for disruptive student behavior. Participants completed four surveys to measure Adverse Childhood Experiences, adulthood trauma, COVID-19-related trauma, and causal attributions for disruptive behavior. Bivariate correlations between each of the trauma history datasets and causal attributions datasets were conducted to investigate these relationships. Two semi-structured interviews with six participants were also conducted and analyzed using deductive and inductive coding processes. Quantitative analyses found a statistically significant relationship between participants’ reported adulthood trauma amounts …

Indirect Dna Transfer To Duct Tape Rolls Stored In Cars, Yuching Chung

Student Theses

This project investigated the accumulation of DNA on duct tape rolls stored in cars. Specifically, we analyzed samples recovered from three areas (the inside, outside, and flat sides) of unused duct tape stored under the driver's seat and trunk of cars for seven days. Twelve volunteers were recruited, resulting in 64 DNA samples from 12 cars. We evaluated DNA quantities and STR genotyping outcomes after amplification with the GlobalFiler™ kit. On average, the DNA yields from under the driver's seat were higher than from the trunk, but the difference was not significant. The inside of the tape roll yielded significantly …

In The Name Of The Mother, The Nation, And The Race: White Women, The Jim Crow South, & Moralized White Supremacist Feminism, Shayna M. Lawson

Theses and Dissertations

This thesis introduces the concept of moralized white supremacist feminism to examine the central role white women played in constructing, legitimizing, and sustaining racial hierarchies in the Jim Crow South through a network of cultural and political organizing, particularly through the United Daughters of the Confederacy and Women’s Ku Klux Klan. Far from passive observers, white women were strategic agents of segregation, leveraging ideals of purity, motherhood, and moral virtue to enforce anti-Black violence and oppression through educational, civic, legal, and symbolic institutions, as well as extra-legal practices. Drawing from archival materials, oral histories, and critical race theory, this study …

Reverse-Chinoiserie: Qing Imperial Porcelain And The Reappropriation Of European Rococo, Yifan (Mia) Ye

Theses and Dissertations

This thesis introduces “reverse-chinoiserie” to describe the Qing court’s reappropriation of European Rococo aesthetics in imperial porcelain. Through case studies of 18th-century ceramic diplomacy and design, it reveals how cultural imitation was reengineered into visual sovereignty. It examines how China responded to, absorbed, and redirected European fantasies of empire.

Intergenerational Transmission Of Health: Evidence From Indonesia, Fatima Khan

Theses and Dissertations

This study estimates the causal transmission of health from mothers to their children. Intergenerational associations in health and other human capital outcomes are well established, but those associations may not be causal due to common unobserved factors between a mother and her child. This study employs two-stage least squares, using weather variation as an instrument, to causally identify the relationship between maternal health and child health outcomes in five dimensions: height-for-age, self-reported health, blood pressure, lung capacity, and hemoglobin levels. The data are from the Indonesian Family Life Survey (1993--2014), a longitudinal survey that provides a 21-year look into the …

The Effect Of An Invasive Species (Lantana Camara) And A Fast-Growing Herb (Acanthus Pubescens) On The Plant And Animal Communities In Kibale National Park, Uganda, Kathleen Bufka

Theses and Dissertations

Fast-growing plant species, like Lantana camara and Acanthus pubescens, could threaten biodiversity in Kibale National Park, Uganda. I surveyed plants and wildlife in areas where these plants were frequently encountered compared to those areas where they are infrequent. I found mixed results based on plant traits and the animals considered. My findings support management efforts on these two species to prevent forest degradation.

Exploring Variability Of The Cg18562578 Methylquant Assay For The Forensic Discrimination Of Monozygotic Twins, Sydney E. Arnold

Student Theses

Monozygotic (MZ) twins possess identical DNA sequences, posing a problem for forensic scientists, as they are incapable of distinguishing MZ twins from each other using traditional DNA identification methods. However, the epigenomes of MZ twins will differ and might be used for their forensic discrimination. Here, we explored the variability of an assay previously developed by our laboratory that showed high discrimination potential for MZ twins using buccal swab DNA, cg18562578 MethylQuant. We measured precision at each step: bisulfite conversion, nested PCR, and qPCR, reproducibility, and repeatability. DNA methylation ratios were compared between two analysts carrying each step using the …

Student Theses

The ever-evolving landscape of technology and its innovations are populating our houses, streets and all kinds of industries. The use of smart devices is booming from most developed nations to underdeveloped countries. The complications which come with the use of the Internet of Things has been an active discussion for the past many years. If we look around in a room of 30 people, we will most likely find double the amount of IoT devices than the people in that room. All of those devices are connected to the Internet, and are communicating with data servers across the world. The …

Cg18562578 Methylquant Assay For The Discrimination Of Monozygotic Twins, Amber P. Chauca

Student Theses

Monozygotic (MZ) twins have identical DNA, making traditional profiling methods insufficient in their discrimination. However, MZ twins can be differentiated by their levels of DNA methylation. Our research group previously developed a methodology to detect cg18562578 DNA methylation levels in MZ twins based on a two- step PCR approach and a cg18562578 MethylQuant Assay. That study generated data for only 64% of the samples it investigated, and showed a discrimination power of 77% to discriminate between MZ twins. Here, we used the same methodology but a different approach to determine DNA methylation in 73 previously unsuccessful twin pairs. We diluted …
