Theses and Dissertations

The ubiquitous presence of nanoparticles (NPs) and nanoplastics (NPPs) and their effects on environmental and human health is a significant concern. They are used in every aspect of our lives, and while they offer many benefits, there are concerns about their impacts on ecosystems and human health. The primary aim of this dissertation is to quantify NP and NPP transformations in the presence of algae and determine how those transformations influence bioavailability. The methodology involves two complementary analytical techniques: single particle (SP) and single cell (SC) inductively coupled plasma mass spectrometry (ICP-MS). These techniques are tested and applied to two …

Birth Of Inspiration: York County, South Carolina, The Setting That Inspired The Clansman, Zachary Alan Lemhouse

Theses and Dissertations

In 1905, Thomas Dixon, Jr., published his controversial novel The Clansman. Monopolizing on racist sentiments held by white southerners, Dixon’s narrative contributed significantly to the perception of the Lost Cause myth and defense of white supremacy in America. The novel, and its subsequent adaptations as a play and the film Birth of a Nation, was inspired by actual events that occurred in Dixon’s ancestral home of York County, South Carolina. Located in the northernmost region of South Carolina’s Piedmont, York County played host to a struggle for civil rights during the Reconstruction Era that garnered national and international …

Aesthetic Judgment: Considering A Contemporary Standard Of Taste, Lydia Margaret Lee

Theses and Dissertations

Originally published in 1757 as part of his Four Dissertations essay collection, David Hume’s essay, “Of the Standard of Taste,” occupies a prominent place in Enlightenment aesthetic studies. Due to an oversaturation of print materials being produced, eighteenth century society was concerned with evaluating and ranking the massive quantities of art being produced. Philosophers such as David Hume attempted to define criteria for determining a standard of taste, aiming to hierarchically rank works of art based on aesthetic experience. For centuries, critics such as Timothy Costelloe, Noel Carroll, David Marshall, Jonathan Friday, James Shelley, and many others have engaged in …

Strain And Redox Engineering For Enhanced Thermoelectric Performance In Transition Metal Oxide Thin Films, Mohammad Jamal El Loubani

Theses and Dissertations

The discovery of highly efficient and cost-effective thermoelectric (TE) materials is essential to envision high-performance TE power generators that enable the direct conversion of waste heat into electricity. Transition metal oxides (TMOs) are considered promising candidates for high-temperature TE applications due to their excellent thermal stability and low cost. However, their maximum power output (power factor, PF = σ•S2) is constrained by the intrinsic trade-off between thermopower (S) and electrical conductivity (σ), both of which are inversely related to carrier concentration. This trade-off poses a significant barrier to improving the performance of TE devices. Among various strategies to overcome this …

Ideologies Of Language, Race, And Time In U.S. Political Discourses, Paige Pinkston

Theses and Dissertations

This dissertation follows how public discourses that emerged during the 2020- 2022 “Critical Race Theory Panic” played out in different contexts and at different scales in the United States, from conservative national media to South Carolina legislative action. While political discourse has become increasingly nationalized (Berry & Sobieraj, 2014), new legislation has largely taken place at the state level (Johnson, 2022). Drawing on over two years of fieldwork and methods of discourse analysis, I thus examine how nationally circulating discourses about race and racism were taken up by South Carolinians to create partisan alignments and distinctions as well as to …

Help-Seeking, Motivation, And Partner Interactions In Couples Affected By Tramatic Brain Injury, Violet Hodge

Theses and Dissertations

Traumatic brain injury (TBI) affects individuals and their romantic relationships, creating barriers to help-seeking and impacting relational health. Despite evidence supporting the benefits of couples counseling and relationship education, stigma and motivational factors influence engagement in these services. This dissertation examines the interdependent processes of help-seeking, motivation, and relationship satisfaction in couples where one partner has experienced a TBI. Using the Actor-Partner Interdependence Model (APIM), two studies explore (1) the role of self-stigma in help-seeking and motivation for completing a relationship education program, and (2) the influence of self-stigma for help-seeking on motivation in couples services, particularly in the context …

Autoregressive Modeling Of Dna Molecule Shapes Accompanied By An Empirical Assessment Of The Ljung-Box Test, David William Custer

Theses and Dissertations

The assumption of independence rarely holds in real-world data. Correlated observations are ubiquitous, especially in sequential contexts where time series models are essential for capturing temporal dependence. This study analyzed six groups of damaged and undamaged DNA sequences, where an "F" in the middle of a sequence indicates damage. One biological aim is to understand how DNA regenerates with the assistance of proteins that recognize damaged regions. Motivated by empirical support for AR(2) modeling, we fit autoregressive models to the first three principal component scores of each DNA group, capturing the dominant structure in the data. We conducted model diagnostics, …

Emotional Landscapes: St. Teresa Of Avila And The Spiritual Journey, Jillian Louise Breeden

Theses and Dissertations

This paper examines the writings of St. Teresa of Avila (1515-1582) through the methodological lens of the history of emotions, arguing that her mystical accounts represent a crucial yet understudied contribution to our understanding of early modern emotional frameworks. Through close textual analysis of Teresa's major works, this study demonstrates how her detailed articulations of spiritual ecstasy, divine love, and religious melancholy offer unique insights into both the religious and secular emotional landscapes of Counter-Reformation Spain. Teresa's innovative emotional vocabulary, which combined traditional Catholic devotional language with embodied metaphors and spatial conceptualizations, allowed her to navigate the complex ecclesiastical politics …

Characterizing The Relationships Between Cranial Geometry, Brain Morphometry, And Brain Mechanical Properties Using Mr Imaging And Elastography, Jessica Restivo

Theses and Dissertations

Traumatic brain injury (TBI) is a global health concern, with over 69 million cases annually. TBI risk depends on subject-specific neuroanatomical variation, yet research often only considers generic finite element (FE) models, based on the geometry and material composition of a 50th percentile male head. Although highly accurate, subject-specific models require expensive magnetic resonance (MR) imaging, elastography, and time-consuming computational resources. There is a need to create subject-specific TBI models that account for subject-specific variations, without neuroimaging. This study aims to create mathematical models to predict brain morphometry (dimensions, volume) [Objective 1] and mechanical properties (shear stiffness, damping ratio, octahedral …

Elevating Next Generation Wireless Devices Towards Contactless Sensing For Healthcare Applications, Aakriti Adhikari

Theses and Dissertations

There is an increasing interest in technologies that can understand and perceive at-home human activities to provide personalized healthcare monitoring, aimed at early detection of disease markers and assisting physicians in making clinical decisions. Existing approaches, such as wearables, require users to wear sensors that can be cumbersome and cause discomfort. Vision based solutions, such as optical cameras, IRs, LiDARs, etc., can be used to design contactless at-home monitoring systems. However, these systems are limited by poor lighting and occlusion, and they are privacy-invasive. Fortunately, high-frequency millimeter-wave wireless devices provide an effective alternative to the existing systems to enable fine-grained …

The Role Of Symmetries In Atomic, Electromagnetic, And Particle Physics, Joshua Martin O'Connor

Theses and Dissertations

Symmetries in atomic, electromagnetic, and weak interaction physics are explored to understand symmetry-breaking extensions of the Standard Model of particle physics. Lorentz-violating field theories are extremely interesting theoretically, since they possess many new features that are absent in Lorentz-invariant models. We outline the formalism and experimental status of the Lorentz- and CPT-violating Standard Model Extension, in both the classical and quantum regimes. Processes such as vacuum Cerenkov radiation, which are kinematically forbidden when Lorentz symmetry is exact may become allowed when this symmetry is weakly broken. Particle decays, such as pion and kaon decays, although allowed in Lorentz-invariant theories, are …

Adult English As A Second Or Other Language Peer Oral Interaction In Online Breakout Rooms, Kathleen Moriarty

School of Education and Leadership Student Capstone Projects

Peer interaction is essential for adult English as a Second or Other Language (ESOL) students' oral skills development. However, it is more challenging to offer peer interaction in online synchronous classes. To support new teachers who begin online teaching, the author reviewed research on peer learning and online classroom interactional competencies. Based on a foundation of second language acquisition theories and communicative teaching practices, oral skills are developed more with specific types of activities in online breakout rooms: task-based, cooperative, and collaborative activities. These activities are inherently social and motivate learners to engage in negotiation for meaning and a focus …

Mtu-Llm: Llm-Based Multi-Robot Task Allocation And Path Planning For Heterogeneous Robots In Search And Rescue Operations, Kaushik Kannan, Jungyun Bae

Michigan Tech Publications

Urban Search and Rescue operations after natural disasters involve locating and assisting victims in hazardous environments, which is challenging. Classical Multi-Robot Task Allocation (MRTA) and path planning approaches have been used to deploy heterogeneous robot teams in unsafe areas. However, existing methods often lack focus on workload balance and requirement fulfillment and struggle to generalize across different scenarios. To address these challenges, we propose Multi-robot Task allocation Utilizing LLMs (MTU-LLM), a framework designed to reduce the development time for task allocation and path planning approaches, enabling faster robot deployment. The framework uses an LLM-based “prompt engineering” approach that generates task …

Faculty, Staff and Student Publications

Introduction: Impaired insulin (INS) and insulin-like growth factor 1 (IGF-1) signaling are features of both brain aging and late-onset Alzheimer's disease (LOAD). However, their exact underlying mechanisms and cause-and-effect linkages, including the downstream regulation of endocytosis and autophagy, are still not well understood.

Methods: We investigated INS/IGF-1 signaling and its connection with endocytic and autophagic processes in fibroblasts from LOAD patients and healthy young or old control individuals.

Results: Compared to control old-age cells, protein levels in the INS/IGF-1 signaling cascade were elevated in LOAD cells, but activation of AKT was reduced. The activation of the INS/IGF-1/AKT/FOXO1 or mTOR axes …

Arterial Anastomosis To Injured Vessels: Outcomes In Lower Extremity Trauma Reconstruction, Ellen Wang, Jessica R Nye, Imran Rizvi, Kylie R Swiekatowski, Bora Kahramangil, Paul Won, Noa G Kopplin, Stephen F Parlamas, Jeffrey G Trost, Mohin A Bhadkamkar

Faculty, Staff and Student Publications

Background: Although traditional teaching advocates that microsurgical anastomoses should be performed to uninjured vessels outside the zone of injury (ZOI), there is no defined way to assess the extent of the ZOI, and uninjured vessels may not be available. To evaluate the complications ascribed to the ZOI and injured vessels, outcomes between arterial anastomoses fashioned from within the ZOI versus noninjured recipient vessels were compared.

Methods: A retrospective review was conducted of adult patients who required lower extremity free flap (FF) reconstruction from 2016 to 2024. Injury to the recipient artery (transection, avulsion, or thrombosis) was determined by intraoperative assessment …
