Model Unification: A Systematic Approach For The Cluster Expansion, Kolten Barfuss

Theses and Dissertations

A systematic approach for model unification of cluster expansion models is developed and demonstrated. The method builds on previous work with the Manifold Boundary Approximation Method (MBAM) to identify supremal models. The work is motivated by the exercise of unifying cluster expansion models – characterized by Π matrices – for two binary alloys that share one atomic species to form a model for the ternary alloy. The result is the Supremal Π Algorithm, a systematic unification algorithm that relies on an MBAM-informed understanding of models and on the singular value decomposition. The algorithm yields ΠΛ, a Π matrix for the …

Single-Walled Carbon Nanotube-Mediated Plasmid Dna Delivery In The Model Monocot Brachypodium Distachyon, Kaya İşleyen Bi̇lge, Bahar Soğutmaz Özdemi̇r

Turkish Journal of Biology

Background/aim: Plant genetic engineering is a valuable approach for improving stress tolerance, crop productivity, and quality traits. However, its progress is limited by the drawbacks of traditional transformation methods. Commonly used techniques, such as Agrobacterium-mediated transformation and biolistics, are restricted by genotype dependency, lengthy tissue culture steps, and low efficiency, particularly in monocot species. Therefore, the development of alternative gene delivery strategies remains an ongoing research focus in plant biotechnology. Nanoparticle-based delivery systems have recently gained attention due to their physiochemical properties, biocompatibility, and potential for alternative gene delivery approaches in plant systems.Materials and methods: We investigated the use of …

Perceived Inadequate Neighborhood Food Shopping And Cardiovascular Disease Risk: The Multi-Ethnic Study Of Atherosclerosis, Amier Haidar, Ghadi Ghanem, Rishi Rikhi, Karol E Watson, Shreela V Sharma, Michael D Shapiro

Faculty, Staff and Student Publications

Background: Individuals with access to healthy food have healthier diets, improved cardiometabolic risk profiles, and decreased cardiovascular disease (CVD). However, previous studies have focused on the neighborhood food environment as distance to and density of food retailers. Our study examines the association between an individual's perceived adequacy of neighborhood food shopping and incident CVD.

Methods: We analyzed data from 6814 participants in the MESA (Multi-Ethnic Study of Atherosclerosis), a prospective cohort study of individuals aged 45 to 84 who were enrolled in the study between 2000 and 2002 and followed longitudinally. Cox proportional hazards models estimated hazard ratios (HRs) for …

Mild Thermal Treatment Of Lithium-Ion Batteries To Optimize Black Mass Production, Brooke Lillie

Theses and Dissertations

This thesis explains the design of equipment and the experimental procedure for thermal treatment of lithium-ion batteries for the purpose of low-cost materials recycling. Conditions used were between 150 ℃ and 425 ℃, involving different atmospheric conditions and treatment durations. The battery samples were processed through a sieve shaker device. Mass loss during the heat treatment, and separation of the battery through sieving was used to analyze the effect of the treatments on separability of black mass from the batteries. Additionally, internal battery temperature was measured and compared to real average furnace temperature to monitor thermal runaway. Testing showed minimal …

The Artificial Maintenance Of Relationship Satisfaction: Romantic Ai Companion Usage Sustains Emerging Adults' Human Romantic Relationship Satisfaction While Eroding Relationship Stability, Rebekah M. Hakala

Theses and Dissertations

As artificial intelligence becomes increasingly sophisticated, romantic AI companions--AI systems designed to simulate romantic, emotional, or sexual relationships--have emerged as a novel relational phenomenon. Nearly one in four emerging adults now engage with romantic AI companions, yet little is known about how this usage affects their romantic human relationships. Drawing on Social Exchange Theory and the Investment Model of Commitment, and employing structural equation modeling, this thesis uses data from 2,431 emerging adults in romantic relationships to examine whether romantic AI companion usage influences relationship satisfaction and relationship stability among emerging adults in the United States (ages 18-30), and whether …

Impacts Of Arbuscular Mycorrhizal Fungi And Novel Soil Amendments On Perennial Grass Establishment In Mineland Soils, Melissa M. Burrell

Theses and Dissertations

Establishing perennial vegetation on mine waste materials is one of the primary challenges in mine land reclamation. Waste rock and mine tailing substrates typically lack the physical structure, nutrient availability, and biological communities necessary to support plant establishment and long-term ecosystem recovery. As a result, revegetation efforts often experience poor seeding success and limited plant persistence despite intensive management efforts. These studies investigated two complementary strategies to improve perennial grass establishment in degraded mine substrates: restoring mycorrhizal associations and enhancing soil function through soil amendments. The first study examined the role of arbuscular mycorrhizal fungi (AMF) in facilitating plant establishment …

Psychosocial Characteristics Of North American Male Cannibals, Sheila A. Murphy

Walden Dissertations and Doctoral Studies

Criminal cannibalism is a rare form of violent offending that remains understudied despite public attention. This gap limits understanding of the psychosocial characteristics and life experiences of individuals who engage in cannibalistic behavior. The purpose of this qualitative study was to explore psychosocial characteristics within the life experiences of North American males who engaged in cannibalistic behavior and identify common themes. Grounded in social control theory and self-control theory, the study examined how weakened social bonds and diminished self-regulation may relate to extreme deviance. The guiding research question focused on identifying common psychosocial characteristics within this population. A descriptive phenomenological …

Perceived Bias And Barriers Among Black Women In Professional Leadership, Rochelle Wilhelmina Gilbert

Walden Dissertations and Doctoral Studies

Black women have long contributed to leadership in academia, government, and the nonprofit sector, yet they remain significantly underrepresented in senior leadership roles in higher education. When Black women are missing from leadership, institutions lose out on talent, students lose out on representation, and society loses out on the full range of perspectives needed to solve complex problems. Grounded in Black Feminist Thought, this general qualitative study explored the experiences and perceptions of bias and barriers among Black women serving in leadership roles at the dean level and above in higher education. Data were collected through structured interviews with seven …

Teachers’ Perceptions Of Preventing Teacher-Directed Violence In Urban Title I Schools, Allison Mashburn

The problem that was investigated through this study was the increase in suspensions for teacher-directed violence at two urban mid-Atlantic Title I elementary schools. The purpose of this qualitative study was to explore elementary teachers’ perceptions of preventing and managing teacher-directed violence in two Title I mid-Atlantic schools. Bronfenbrenner’s ecological framework was used as the foundation for environmental explanations. For this basic qualitative design, semistructured interviews with 10 teacher participants were conducted. The thematic analysis resulted in three themes based on the teacher request for (a) classroom management resources and supports, (b) clarifying the code of conduct, and (c) improving …

Journey Of Becoming: Risk And Self-Determination In The Story Of Self For Adults With Intellectual, Developmental, And Learning Disabilities A Phenomenological Case Study Employing Narrative Inquiry And Thematic Analysis, Christopher R. J. Worth

Dissertations

This phenomenological case study, employing narrative inquiry and thematic analysis, captured the first-person voice of emerging adults (ages 20–28) with intellectual, developmental, and learning disabilities to explore how experiences of risk and self-determination shaped their personal narratives, or story of self. Guided by Critical Disability Theory, Foucault’s concept of relational power, and Shogren’s Causal Agency Theory, the study challenged the systemic bubble-wrapping that denies this population the "dignity of risk" (Perske, 1972). Data were collected from six participants through semi-structured interviews, adapted photovoice submissions, and participant selfreflections. The findings revealed that the phenomenon of becoming, catalyzed by intellectual adaptive risk-taking, …

On The Transport Of Chloroplast Lipids, Cailin Smith

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Chloroplasts are green, photosynthetically active organelles ubiquitous to the plant kingdom. Owing to their cyanobacterial origin, chloroplasts consist of three membranes: the outer envelope, the inner envelope, and the thylakoid, the latter of which is the site of the light-dependent reactions of photosynthesis. Not only do the lipids that make up these membranes delineate aqueous compartments, but they also respond dynamically to developmental and environmental cues, constitute the matrix that scaffolds protein machinery, and even serve as functional components of some proteinaceous complexes. However, while lipids are of vital importance to the structure and function of the chloroplast, the mechanisms …

Awareness, Protest, And Action: Women Science-Fiction Writers As Writer Activists, Carolyn Nolte

Dissertations and Doctoral Documents, University of Nebraska-Lincoln, 2023–

Following the end of World War II, science-fiction literature, which was mostly dominated by white male writers, experienced an increase in stories written by women writers. Of these postwar stories written by women, the three women writers in this dissertation imagined how their present-day experiences informed the future by exploring their concerns about humanity’s collective trajectory. By analyzing how their stories dramatize possible future social, psychological, biological, and environmental harms, this dissertation argues that these women writers’ works distinguish them as writer-activists, a concept I borrow from Rob Nixon’s work Slow Violence and the Environmentalism of the Poor.

When Metal Theft Becomes A Life Safety Crisis, Alan Saquella

Publications

By any traditional measure, scrap and metal theft has long been categorized as a property crime, costly, disruptive, and frustrating, but rarely viewed as an immediate threat to human life. That framing, however, no longer reflects reality. What was once considered a nuisance crime has evolved into something far more consequential, particularly when it intersects with critical infrastructure.

Building on the risks outlined in “Scrap Disposal: When the End of the Supply Chain Becomes a Brand and Public Safety Risk,” by Marcos Fontes, a more serious dimension comes into focus when essential systems are targeted. In these cases, the impact …

Development And Flight Of Stratospheric Missions For Hard X-Ray Polarimetry And Hard X-Ray Spectroscopy, Ephraim Gau

Arts & Sciences Graduate Student Theses and Dissertations

The recent launches of the {\it Imaging X-ray Polarimetry Explorer} ({\it IXPE}\,) and {\it XRISM} have provided significant advances to the realms of polarization and high-resolution spectroscopy in X-ray astrophysics. However, both of these satellite missions conduct measurements in the soft X-rays, below 10 keV. To obtain a complete picture of any astrophysical source, we must extend these capabilities to the hard X-rays, above 10 keV, as well. Thus, in my graduate work, I have directed my efforts in these two regimes: measuring the polarization of hard X-rays with {\it XL-Calibur}, and improving the energy resolution of hard X-ray telescopes …

Some Closure On The Relation Between Cfg And Peg, Nathan J. Bulloch

Theses and Dissertations

We work toward a practical, unified language formalism for structurally recursive languages by expressing the mathematical theories underlying context-free grammars with lookahead (CFGLA) in the Rocq theorem prover and leveraging CFGLA semantics to analyze interactions between between recursion and negative lookahead. We give examples of grammars with left-recursive negation cycles for the parsing expression grammar (PEG) variant due to Medeiros et al. and for the translation from PEG to CFGLA due to Miyazaki and Minamide. To study the interaction between left recursion and negative lookahead in a PEG context, we introduce FPEG, a left-recursive extension of PEG with Fitting semantics.

The Scholastic Trombone Ensemble: Instructional Guide And Custom Arrangements For Secondary School Trombone Choir, Cassidy Clayton Shiflett-Cockrell

Electronic Theses and Dissertations Archive

ABSTRACT The trombone ensemble is an increasingly popular academic tool for young collegiate players to cultivate musicianship and ensemble skills. Because this setting exclusively uses trombones, it is excellent for training intonation, resonance, and overall blend. I was first introduced to performing in a trombone ensemble during my undergraduate studies at the University of North Alabama through a trombone quartet. The time I spent learning to listen and blend with my colleagues was foundational to developing the critical ensemble skills I still use frequently. Throughout my following studies at The University of Akron and the University of Memphis, respectively, the …

Opportunistic Breast Cancer Detection With Photon-Counting Ct: A Quantitative Pilot Study Of Reconstruction-Dependent Image Quality, Graham Hannon

McKelvey School of Engineering Graduate Student Theses & Dissertations

Photon-counting computed tomography (PCCT) has emerged as a promising imaging modality with improved spatial resolution and contrast capabilities compared to conventional energy-integrating detector systems. These advantages present an opportunity for opportunistic detection of breast cancer in routine thoracic CT scans that include breast tissue. In this pilot study, we evaluated the feasibility of opportunistic breast cancer detection using clinical PCCT data through quantitative image analysis. Two patients with confirmed breast malignancies and corresponding thoracic PCCT scans were retrospectively analyzed. Dedicated reconstructions were performed with varying convolution kernels, field-of-view sizes, and virtual monoenergetic spectra. Image quality was assessed using signal-to-noise ratio …

Exploring The Role Of Family Engagement In Youth Behavioral Health Programs, Jordon R. Washington-Trahan

Walden Dissertations and Doctoral Studies

The behavioral health leaders at Organization X do not have a clear and practical way to engage family members in youth behavioral health programs. When caregivers are not actively involved in youth behavioral health treatment, youth may disengage from missed appointments and discontinue treatment prematurely. The present case study focused on Organization X, a small behavioral health organization located in the Southeastern United States. The Baldrige Framework of Excellence was the conceptual framework for this study, with a focus on consumer engagement and workforce operations. Semi structured and structured interviews were conducted with three behavioral health leaders. Data were collected …
