Optimizing Practice Facilitation: A Comprehensive Study On Implementation Fidelity And Its Determinants, Demetria Marie Hubbard

ETDs from 2020-2029

Intervention outcomes cannot be fully understood without examining how implementation strategies are delivered. While implementation fidelity to interventions is well recognized as a determinant of effectiveness, the fidelity of implementation strategies—the methods used to support intervention adoption—remains under-documented and under-assessed. Without this information, it is difficult to contextualize why interventions succeed or fail across diverse settings. This three-paper dissertation focuses on practice facilitation (PF), a widely used strategy in primary care quality improvement, as implemented in the Heart Health Improvement Project (HHIP) in Alabama. HHIP, led by the Alabama Cardiovascular Cooperative and funded by the Agency for Healthcare Research and …

Integrated Proteomics To Understand The Role Of Neuritin-1 (Nrn1) As A Molecular Mediator Of Synaptic Resilience In Alzheimer’S Disease, Derian Pugh

ETDs from 2020-2029

Alzheimer’s disease (AD) is the leading cause of dementia in adults over the age of 65, and currently affects approximately 6.9 million people in the United States. By 2060, the number of people age 65 and older with AD is projected to reach 13.8 million, barring the development of disease-altering therapies to prevent, slow or cure AD. Thus, there is a need for progress in the understanding of AD pathophysiology, as well as in the development of diagnostic and therapeutic interventions. Approximately one-third of individuals without dementia at the time of death are found to harbor high levels of amyloid-beta …

Cysteine Protease Activity In Allergen Recognition And Initiation Of Th2 Allergic Responses, Audrey Rae Meloun

ETDs from 2020-2029

Allergens are non-infectious environmental proteins that can trigger T helper 2 (Th2) cell-mediated inflammation in atopic individuals. Allergens are structurally diverse and typically lack pathogen-associated molecules patterns (PAMPs), which are recognized by pathogen recognition receptors (PRRs). PRRs are the canonical sensors of the innate immune system that typically detect PAMPs in microbes, initiating signaling pathways that drive pathogen clearance. Because allergens generally do not activate PRRs in the same way as infectious agents, alternative detection mechanisms are likely responsible for their recognition and the subsequent initiation of Th2 cell-mediated inflammation. House Dust Mite (HDM), a major indoor allergen, and other …

Exercise Testing And Training For Individuals With Cystic Fibrosis, Najlaa Zayed Alotaibi

ETDs from 2020-2029

Cystic fibrosis (CF) is a progressive genetic disease that impacts multiple systems (e.g., respiratory system). Hence, routine cardiopulmonary exercise testing (CPET) is recommended to track the disease progression in people with CF. Besides the benefits of exercise testing, exercise training is also beneficial for long-term wellness. It is recommended that people with CF engage in at least 30–60 minutes of aerobic exercise 3 days a week. However, despite the significance of exercise testing and training for people with CF, CPET and exercise training are underutilized in international CF centers. According to the literature, the majority of international CF centers use …

Physical And Psychophysiological Responses To Self-Selected Music In Individuals With Parkinson's Disease, Sophia Porrill

ETDs from 2020-2029

Exercise is a cornerstone adjunct therapy for people with Parkinson’s Disease (PwP). However, exercise capacity is often impaired by non-motor processes including decreased motivation, arousal, and physical effort. Self-selected music (SSM) has been shown to improve motivation and arousal state in healthy individuals thereby leading to increases in exercise capacity. Whether these positive effects of SSM translate to PwP is unclear. The purpose of this study was to measure 1) the psychophysiological effects of SSM at rest, and 2) psychophysiological and physical responses during a 6-minute walk test (6MWT) in PwP. In a counterbalanced crossover manner, PwP (n=12) completed resting …

Analysis Of Activated Carbon Fiber (Acf) As Particulate Filtration And Volatile Organic Compound (Voc) Media For The Development Of A Dual-Air Purifying Facepiece Respirator, Brie Mcmahan

ETDs from 2020-2029

Exposure to particulate matter (PM) and volatile organic compounds (VOCs) in occupational or public settings poses adverse health outcomes such as respiratory, cardiovascular, reproductive, neurological, carcinogenic morbidity and mortality. Many occupational settings expose workers to PM and VOC concurrently, yet most commercially available respirators are designed to address either particulates or vapors alone. This includes air-purifying respirators (APRs), powered air-purifying respirators (PAPRs), and filtering facepiece respirators (FFRs) with nuisance-level vapor protection, often limited by bulk, discomfort, high pressure drop, and misuse. We identified a need for alternative dual-exposure media and a respiratory protection device that is lighter, and more comfortable …

Impositions, Christopher Michael Mccauley

ETDs from 2020-2029

This collection explores ordinary moments. A couple on a park bench. A man cleaning a horse stall. A citizen scientist wandering a field. When you peer into these scenes closely, though, you can move beyond the seemingly mundane and discover universal truths, as well as images that evoke shared emotional landscapes. Two primary themes bring greater clarity to these moments and images: people imposing on the world and the world imposing on people. Each piece in the collection touches on these themes in some way. Hence the title, Impositions. I hope readers will feel a sense of empathy for the …

Understanding Mobility Limitations And Public Transportation Accessibility For People With Disabilities, Jada Meria Stringer

ETDs from 2020-2029

Mobility for people with disabilities (PWDs) depends on both the availability of transportation and public services and the accessibility of these systems. The presence of public transportation systems does not ensure usability. Vehicles, infrastructure, and the built environment must be designed to accommodate diverse physical, sensory, cognitive, and other needs. PWDs must also be able to navigate public buildings and surrounding spaces safely and comfortably. This thesis examines mobility limitations for PWDs in India and the United States, focusing on accessibility along the full mobility chain. A review of existing literature provides context on accessibility policies, design standards, and the …

Untold Journeys: A Case Study Of Attrition In Alabama’S Public School Teaching Workforce, Jessica Claborn Rose

ETDs from 2020-2029

This exploratory multiple-case study investigates the crisis of teacher attrition among early childhood and elementary education graduates from Alabama-based teacher education programs (TEPs) who either avoided public-school teaching or left the profession within three years. The research, guided by Bandura’s social cognitive theory (SCT) and Maslow’s human motivation theory, utilized a qualitative design involving individual interviews with ten teacher leavers (TLs), and five TEP faculty members. The findings reveal that attrition is a multi-faceted crisis rooted in systemic failures, coalescing around two overarching factors: effectiveness of support systems and a collection of barriers. Consistent with SCT, low self-efficacy, resulting from …

Biomineralization Of Low Temperature Plasma(Ltp) Modified Polymeric Biomaterials And Scaffolds, John Patrick Bradford

ETDs from 2020-2029

Bio-integration, specifically osseo-integration of bone implants and scaffolds, are vital for the success of implants and bone tissue engineering (BTE). Calcification can be defined as the deposition of calcium compounds as either calcium phosphate(CaP) minerals consisting of hydroxyapatite(HAP) or CaP salts. The significance of the variety of phases of CaP is that mature bone matrix is composed of 65% CaP mineral. Many investigators have attempted to model the natural matrix by producing materials containing calcium phosphate in both amorphous CaP or in the more crystalline HAP form, with biomaterials (both synthetic and biological). Biomimetic CaP formation is a sign of …

Development Of Human Trophoblast Cell Surface Antigen-2 (Trop-2) Specific Radiopharmaceutical Tracers, Arnav Vipulkumar Patel

ETDs from 2020-2029

Trophoblast cell surface antigen 2 (Trop2) is closely related to the development and progression of triple-negative breast cancers (TNBC) and is also being investigated as a pan-cancer biomarker. Trop-2 tumorigenesis is mediated by the calcium ion signaling pathways. By accurately predicting and targeting Trop-2 for immunotherapy, precision therapy is crucial. Trop-2 is overexpressed in tumor tissues compared to normal tissues, which makes it a promising molecular target for cancer-targeted therapy. This thesis reports the development and preclinical evaluation of two novel Trop-2-specific radiopharmaceutical tracers derived from the clinically approved antibody-drug conjugate Sacituzumab Govitecan (SG): a full antibody drug conjugate-based tracer …

Quantum Technologies, Part One: Focusing A Bit Upon Realities, James Giordano

Strategic Insights

This commentary examines the current realities of quantum technologies and their implications for national security and defense. While quantum systems are often described as revolutionary, their practical military impact remains uneven and frequently overstated. This analysis reviews three key domains—quantum computing, sensing, and communications, and explains where these technologies currently outperform classical systems and where significant technical limitations remain. In particular, quantum computing is still in a “noisy, intermediate-scale” stage, meaning most applications remain experimental and dependent on advances in error correction, algorithms, and hardware. Understanding both the promise and limitations of quantum technologies is essential for shaping realistic defense …

This approach eliminates the need …

Device Dilemma, Monica Munaretto

General Submissions: Clinical Settings Materials

Hematopoietic Cell Transplantation (HCT) is a treatment modality employed for many types of hematologic malignancies and some autoimmune disorders. Several types of access devices can be used for HCT including implanted ports, tunneled, and non-tunneled central catheters. Assumptions exist, however, that implanted ports may lead to higher rates of infection and impede engraftment. The aim of this study was to explore the use of an implantable port during HCT, potential complications associated with port presence and use, and success of engraftment when using the port to infuse stem cells.

Hybrid Quantum-Classical Optimization Of The Resource Scheduling Problem, Tyler Christeson, Md Habib Ullah, Ali Arabnya, Amin Khodaei, Rui Fan

Electrical and Computer Engineering: Faculty Scholarship

Resource scheduling is critical in many industries, especially in power systems where the Unit Commitment (UC) problem determines the on/off status and output levels of generators under physical and economic constraints. Traditional exact methods, such as Branch-and-Bound, Branch-and-Cut, dynamic programming and mixed-integer linear programming (MILP), remain the backbone of UC solution techniques, but they often rely on linear approximations or exhaustive search, leading to high computational burdens as system size grows. Metaheuristic approaches, such as genetic algorithms, particle swarm optimization, and other evolutionary methods, have been explored to mitigate this complexity; however, they typically lack optimality guarantees, exhibit sensitivity to …

Carrasquillo V. 303 W. 122nd St. Hous. Dev. Fund Corp.

All Decisions

The Appellate Division affirmed the denial of the tenant's motion for a preliminary injunction to prevent the sale of co-op shares or termination of the proprietary lease. The court found the tenant failed to demonstrate a likelihood of success on the merits, primarily by not proving the landlord breached the warranty of habitability; cited violations were largely corrected, and the tenant denied access for repairs. Furthermore, the notice to cure was deemed valid. As the tenant defaulted on the loan agreement, the landlord was permitted under UCC § 9-610[a] to sell the shares or terminate the lease.

Common Octopus (Octopus Vulgaris) Blooms Off The Southwest Of The Uk: History, Trends, Causes And Consequences.: Report On Work Package 1: History, Causes And Consequences Of Octopus Blooms, Bryce Stewart, Simon Thomas, Tim J. Smyth, Molly K. James, Emma Sullivan, Alice Hall, Tully Osmond, Emma Sheehan

School of Biological and Marine Sciences

Common octopus (Octopus vulgaris) are normally uncommon in UK waters, with a mainly south-westerly distribution linked to the species’ preference for warmer conditions. However, a major population bloom occurred off southwest UK in 2025, comparable to rare historical blooms recorded in 1899–1900, 1932–33 and 1950–51. The species’ rapid growth, high fecundity and short lifespan make its populations highly responsive to environmental conditions. Evidence from fisheries landings, scientific surveys and citizen science confirmed the bloom, with commercial fisheries landings of common octopus in 2025 being almost 65 times higher than recent annual averages. The 2025 bloom and all previous blooms were …

Seizure Presentation Of A Grade Ii Astrocytoma In A Patient With Ollier's Disease: A Case Report And Brief Review, Marissa Vail, Hunter Slosser, Robert Steele, Brian Curtis, Daniel Henry

Student Publications

Ollier's disease (enchondromatosis) is a dysplasia of cartilage characterized by multiple enchondromas. Current evidence supports a measurable prevalence of concurrent gliomas in patients with Ollier's disease. In patients with Ollier's disease, isocitrate dehydrogenase 1 (IDH1) and isocitrate dehydrogenase 2 (IDH2) mutations were shown to be a predisposing factor to the development of astrocytomas in conjunction with subsequent mutations in adenosine triphosphate (ATP)-dependent helicase ATRX (ATRX) and tumor protein p53 (TP53). We present the case report of a 21-year-old man with an adolescent diagnosis of Ollier's disease who developed a grade II astrocytoma in early adulthood. The patient presented to the …

The Global Extent Of The Grassland Biome And Implications For The Terrestrial Carbon Sink, A S. Macdougall, B Vanzant, J Sulik, S Bagchi, D Naidu, T O. Muraina, E. Hersch-Green

Michigan Tech Publications

Land cover data are commonly used to model the terrestrial carbon (C) sink, yet these data have wide margins of error that significantly alter estimates of global C storage. Here we demonstrate this data vulnerability in grasslands, which are critical to C cycling but whose estimated distribution has varied by >50 million km (3.5-42% of the Earth's terrestrial surface). Comparing multiple high-resolution land cover products with expertly annotated grassland data from six continents, we show sources of mapping error and discuss C implications based on 2023 United Nations (UN) FAO estimates. Past misidentification arose from inconsistent definitions on grassland identity …

Structures Of Invertebrate Pezo-1 Isoforms With A Compact Architecture And A Dispensable Pore-Distal N-Terminal Blade, Briar Bell, Angela M Jaramillo-Granada, Daniel J Orlin, Wei-Hsiang Weng, Haosheng Wen, Marcos Sotomayor, Alexander T Chesler, Matthew L Baker, Julio F Cordero-Morales, Valeria Vásquez

Faculty, Staff and Student Publications

PIEZO channels are mechanosensitive ion channels conserved from plants to humans, yet structures exist for only a few mammalian orthologs. We define the structural and functional diversity of Caenorhabditis elegans PEZO-1, a single gene with extensive alternative splicing, by determining cryo-electron microscopy structures of three representative isoforms: G (full length), K (lacking the pore-distal N-terminal blade), and L (missing most of the blade). PEZO-1G displays mechanically evoked currents yet adopts a compact, semi-flattened conformation that significantly differs from the mammalian domes. The blades exhibit a three-step slope architecture stabilized by inter-blade latching among transmembrane helical units, yielding a circular, steering-wheel-like …
