This study evaluated the feasibility, acceptability, and preliminary outcomes of a group-based CBTi intervention adapted for individuals with Parkinson’s disease. Participants engaged in a six-week group intervention that incorporated Parkinson’s-specific adaptations. Preliminary findings indicated that the adapted group CBTi intervention was generally feasible and …

Use Of Transcranial Magnetic Stimulation As An Assessment Of Corticospinal Excitability In Individuals With Persistent Postural Perceptual Dizziness, Elizabeth Cornforth

Theses and Dissertations

Persistent postural-perceptual dizziness (PPPD) is a common, disabling, chronic vestibular disorder whereby individuals experience symptoms of non-vertiginous dizziness, unsteadiness, and sway or rocking that are present most hours of the day, most days of the week. Individuals with PPPD have been noted to have an increased burden of dizziness and reduced quality of life compared to other dizziness diagnoses. The cause of PPPD is not well understood which can lead to years of diagnostic testing, failed therapies, and poor symptom management. It is important to understand PPPD pathophysiology so that optimal treatment interventions can be developed for this disorder to …

Proof Of Recovery: A Model To Enhance Data Integrity In Data Management Systems, Gustaf Barkstrom

Nanomagnet Based Straintronic Devices For Unconventional Computing: Simulation And Performance Analysis, Rahnuma Rahman

Theses and Dissertations

Nanomagnetic devices are of great interest in digital hardware because of their non-volatility and dynamic ability to change magnetization but suffer from high switching error rates and temperature sensitivity. Magnetostrictive nanomagnets that utilize strain to switch between stable magnetization states encoding bit information are of interest since they are extremely energy efficient as piezoelectric layers can be used to rotate magnetization that have switching energies in the range of attojoules. Their stochasticity can also be useful in probabilistic, analog, neuromorphic, and collective computing systems, where occasional switching errors are not devastating. The dissertation extends spintronics beyond conventional computing schemes by …

A Qualitative Analysis Of Teacher-Report Modifications Of A Tier 2 Evidence-Based Program In Elementary Schools After Implementation Supports Are Withdrawn, Navneet Kaur

Theses and Dissertations

Growing literature emphasizes the importance of examining modifications (i.e., responses to unforeseen challenges and deliberate changes to a program) made by implementers to understand the long-term outcomes of evidence-based programs (EBPs), particularly after formal implementation supports, such as training and coaching, are withdrawn. Although prior research has documented that they occur during implementation, less is known about whether modifications occur once external supports are no longer available, and if so, what types of modifications are made, and the rationale for them. This gap is especially salient in school settings for teacher-delivered interventions. To address this gap, this study used semi-structured …

Local Lung Delivery Of Ginkgetin For Therapeutic Intervention In Lung Fibrosis, Cimone L. Richardson

Theses and Dissertations

Lung fibrosis (LF) is a progressive, irreversible pathological condition in the lungs that is ultimately fatal. Current drug treatments (nintedanib, pirfenidone, and nerandomilast) slow disease progression but cause significant systemic adverse effects due to oral administration. Transient receptor potential vanilloid 4 (TRPV4), a mechanosensitive ion channel, may play a role in LF progression and represent a novel anti-LF target. Ginkgetin (GKT), a natural biflavonoid, is a potent TRPV4 inhibitor with anti-inflammatory and antioxidative properties. Local lung delivery could achieve high local lung concentrations while minimizing systemic exposure. Accordingly, this project evaluates GKT's therapeutic intervention efficacy in LF via local lung …

Mission engineering has been deployed in military scenarios to model human-autonomy cooperation. By applying the concepts from this field to UAM, full systems-of-systems can be …

Examining Bidirectional Associations Between Mothers’ Beliefs About Emotions And Child Social-Emotional Outcomes, Sydney Sumrall

Theses and Dissertations

Social-emotional (SE) skills encompass the ability to recognize and regulate emotions, manage behavior to act on goals, and maintain social relationships (Abrahams et al., 2019). Parents play a crucial role in child SE skill development. According to theories of emotion socialization (ES), the beliefs parents hold about emotions shape parents’ ES behaviors, including teaching children how to understand and express feelings (Eisenberg et al., 1998; Gottman, 1996). Because emotion socialization practices are influenced by cultural values (Raval & Walker, 2019), the parent beliefs and ES strategies that best support children’s SE skill development may vary across families’ racial backgrounds. Although …

Real-Life Health Applications Of Wireless Sensing Using Edge Devices, Md Touhiduzzaman

Theses and Dissertations

Wireless sensing has emerged as a transformative paradigm that leverages ubiquitous radio-frequency signals for environmental perception and human activity recognition beyond their primary role in data communication. Unlike wearable sensors and camera-based systems, wireless sensing offers a non-intrusive, privacy-preserving, and cost-effective alternative that operates seamlessly under low-lighting conditions, through walls, and in non-line-of-sight (NLoS) scenarios. The growing availability of edge computing devices further enables real-time on-device data processing, making wireless sensing solutions highly suitable for in-home health monitoring and smart living applications. This dissertation investigates real-life health applications of wireless sensing through four completed systems, each addressing a distinct challenge …

Dielectric Grating Integrated Hg1-Xcdxte (Mercury Cadmium Telluride) Infrared Photodetectors For High Operating Temperature, Mohammad Ariful Hoque Sojib

Theses and Dissertations

Mercury cadmium telluride (Hg1-xCdxTe, MCT) infrared photodetectors typically require cryogenic cooling to suppress thermal noise, limiting their adoption in size, weight, power, and cost (SWaP-C) constrained military and commercial systems. This dissertation investigates dielectric grating array integration as an extrinsic route to high operating temperature (HOT) detection in Auger-suppressed MCT architectures. Finite element modeling shows that a grating assisted light coupling into a subwavelength (1.5 µm) Hg0.762Cd0.238Te mid-wave infrared layer acting as an absorptive waveguide, achieves photocarrier generation rate comparable to a conventional bulk (e.g., 5 µm) layer. For long-wave infrared detectors, coupled FDTD and drift-diffusion modeling, together with a …

The Intertemporal Law Doctrine’S Application To The Acquisition Of Colonies In The Americas, Kent Mcneil

All Papers

The intertemporal doctrine provides that international disputes have to be resolved in accordance with the international law that existed at the time the events giving rise to the dispute took place, not at the time the matter is adjudicated.1 It is thought to be impermissible to apply current standards to events that occurred in the past when different legal principles and rules were the norm. This doctrine applies as much to acquisition of colonies as to other international issues.2 So in order to determine whether a European nation acquired sovereignty over an overseas territory, it is necessary to determine and …
