Effective Strategies To Implement Energy-Efficient Practices In Enterprise Cloud Data Centers: A Qualitative Pragmatic Inquiry, Joshua Tremayne Campbell

Walden Dissertations and Doctoral Studies

Cloud computing has increased electricity use in data centers, leading to higher costs and a larger carbon footprint. Information Technology (IT) leaders need to address this, as such inefficiencies will increase operational costs, undermine sustainability commitments, and leave companies unprepared for future regulatory pressures. Energy-efficient technologies can reduce data center energy consumption by 40-60%, yet few studies examine the qualitative processes behind IT leaders' practices. The specific IT problem is that some IT leaders lack effective strategies to implement energy-efficient practices in enterprise cloud data centers. Grounded in the technology-organization-environment (TOE) framework, the purpose of this qualitative pragmatic inquiry was …

This dissertation is primarily computational and applies and develops electronic-structure and continuum models, respectively, and a newly implemented physical dipole treatment of the photoelectron to account for these resonances and to interpret experimental photoelectron imaging data. The content of the dissertation is divided …

Prenatal Health Factors Of Pregnant People Associated With Second Degree Postpartum Hemorrhage Across The United States, Elizabeth Simpler

Walden Dissertations and Doctoral Studies

Secondary postpartum hemorrhage (SPPH) is a significant contributor to maternal morbidity in the United States and occurs after hospital discharge during the postpartum period. Persistent disparities in terms of maternal outcomes suggest access to prenatal care alone may not adequately address clinical and social factors associated with SPPH. Guided by the Social Ecological Model, which recognizes that health outcomes are influenced by a collective approach to examining health. The purpose of this study was to examine associations between SPPH, prenatal care access, and social determinants of health from 2019 to 2022 while controlling for maternal age, race, and delivery type. …

Influence Of National Policies In Addressing Intimate Partner Violence In Sierra Leone, Yatta Matilda Musa

Walden Dissertations and Doctoral Studies

Intimate partner violence (IPV) has been shown to be a critical public health and human rights crisis in Sierra Leone driven by patriarchal sociocultural norms. However, despite legislative frameworks like the Domestic Violence Act of 2007, IPV incidents continue to rise, revealing a gap in policy implementation and real-world enforcement. Past research has documented IPV prevalence, yet an empirical evaluation assessing how stakeholders viewed the impact of national policies on prevention and response had not been conducted. The purpose of this study was to explore frontline stakeholders' perceptions regarding the operational influence of existing IPV policies. Grounded in the narrative …

Hypnotherapists’ Perspectives On Using Hypnosis To Address Somatic Symptoms In Clients With Psychological Distress, Tina Wilkerson

Walden Dissertations and Doctoral Studies

Somatic symptoms accompany psychological distress and can affect well-being. Hypnosis has demonstrated effectiveness in reducing psychological distress and related somatic symptoms, but limited research has explored hypnotherapists’ perspectives on its clinical application. The purpose of this qualitative phenomenological study was to explore the experiences of licensed hypnotherapists with 3 years of experience using hypnosis to treat adults experiencing somatic symptoms associated with psychological distress. Guided by Engel’s biopsychosocial model and Hilgard’s neodissociation theory, data were collected through semistructured interviews with 10 licensed hypnotherapists and analyzed using phenomenological reduction and thematic analysis. Analysis resulted in four primary themes: (a) mind–body connection …

School of Geography, Earth and Environmental Sciences

Studying life in the deep, rocky subseafloor involves many layers of technological and methodological challenges, and each drilling project or expedition must make a series of choices to address these challenges. We report on the workflow for sampling hard rock cores for microbiological and biogeochemical research that was developed and optimized during International Ocean Discovery Program (IODP) Expedition 399. All steps of the workflow, including selection of the sample and its shipboard homogenization and subsampling for specific analyses, were designed to maximize the potential for interdisciplinary collaborations and syntheses of results. Furthermore, multiple strategies to minimize and detect potential microbial …

Interplay Between Patterning And Morphogenesis During Zebrafish Embryonic Development, Chia-Teng Chang

Arts & Sciences Graduate Student Theses and Dissertations

Patterning and morphogenesis occur concurrently during embryonic development. In many contexts, both processes are regulated by morphogen signaling: morphogens specify spatially organized cell identities while also influencing the cell behaviors that shape tissues. This creates a reciprocal problem. Morphogen signaling can affect how cells move, while cell movement can change how cells experience and interpret morphogen signals. This dissertation investigates this reciprocal problem during zebrafish gastrulation and neurulation. First, it examines how the ventral-to-dorsal bone morphogenetic protein (BMP) activity gradient regulates germ-layer morphogenesis during gastrulation. BMP signaling is known to pattern dorsal–ventral cell fate and regulate mesodermal convergence and extension …

Closing The Gap In Offshore Wind Environmental Evidence Chains: A Workshop-Derived White Paper, Jiaxin Chen, Lilian Lieber, Matthew Palmer, Dan Lear, Deborah Greaves

School of Biological and Marine Sciences

Offshore wind development is accelerating at a time when environmental assessment is increasingly required to support timely consenting, cumulative-effects understanding, nature recovery, regional planning, floating offshore wind deployment and public trust. The workshop underpinning this White Paper was convened in recognition that the sector's central challenge is no longer simply a lack of data, but the weak connection between data, monitoring approaches, models, uncertainty, governance and decision-making.Environmental monitoring often remains project-specific and receptor-focused, while models remain component-specific or scenario-specific. Data systems are similarly fragmented across owners, repositories, formats, access arrangements and project lifecycle stages. Yet regulators and statutory advisers require …

Experiences Of Psychological Recovery From Work In Second-Generation Asian Americans, Laura Yang

Dissertations and Theses

Individuals of Asian descent make up approximately 7.4% of the U.S. population. As one of the fastest-growing minority groups, their population is projected to reach nearly 15% by 2065, with 38% being foreign-born – surpassing all other racial minority groups. Despite their increasing presence in the U.S. workforce, research on Asian workers' nonwork experiences remains limited. One key unexplored area is how Asian workers engage in recovery after work, considering their unique cultural and racialized experiences. Drawing on literature examining psychological recovery from work, this qualitative study employed multiple methods of analysis, both listening guide method and thematic analysis, to …

Co-Opting Modernity: The Semantic Retooling Of Faith At The 1893 World’S Parliament Of Religions, Erik P. Palmer

The Thetean: A Student Journal for Scholarly Historical Writing

The 1893 World’s Parliament of Religions in Chicago served as a high-stakes arena where the boundaries of religious legitimacy were redrawn through the intentional adoption of social science vocabulary. Staged within the Neo-Classical architecture of the White City of the World’s Columbian Exposition, the event was more than a civil gathering; it functioned as a “Museum of Faiths” where religious traditions were curated, categorized, and evaluated against the perceived benchmarks of Western civilization. The physical environment of the Fair, a monument to industrial triumph, was built to display things that worked. The organizers demanded that religions demonstrate they were useful …

Moving Forward, Looking Back: How Mormon Women Sought To Carry Their Polygamous Past Into A Progressive Future Article, Evan Janis

The Thetean: A Student Journal for Scholarly Historical Writing

The influence of woman is fully recognized.” These words, spoken by Emily S. Richards, echoed the shared mission of Utah women at the World’s Congress of Representative Women: to overturn the public perception of them as ignorant, crude, and barbaric. After decades of legal and social campaigns against the so-called “second barbarism” of polygamy, the reputation of Mormon women had been one of its greatest casualties. Cast as too homely to marry a respectable man, too naive to resist deception, and too submissive to think for themselves, the Utah delegation to the 1893 Chicago World’s Fair sought to redefine their …

From Cotton To Canyons: An Analysis Of The Historic Industries Of Southern Utah, Brielle Beardall

The Thetean: A Student Journal for Scholarly Historical Writing

On October 6, 1861, Brigham Young stood before Latter-day Saints gathered in the Old Salt Lake City Tabernacle and called 300 missionaries on an ambitious undertaking: Over three hundred families would leave their homes and settle in the Utahn southwestern desert; a region that earned the nickname of “Utah’s Dixie” for both its southern location and its punishing heat. Their mission was to cultivate cotton and increase Utahn economic independence from the Confederacy during the American Civil War. Allen Joseph Stout recalled in a personal journal about his experience learning of the call to Southern Utah, “My neighbors reported that …

Le Roi Shrinks Before La Nation And La Liberté: Feminine Allegories And The King In French Revolutionary Prints, Jared Cluff

The Thetean: A Student Journal for Scholarly Historical Writing

Printers in the early years of the French Revolution faced an unprecedented problem with new, unprecedented legal flexibility. Though the most cohesive government-coordinated efforts to overturn old symbols and refashion France’s national identity would not come until the Republican period, French engravers in the early years of the Revolution found existing Old Regime symbols and visual codes inadequate tools, so sought “a visual formula for [this] unprecedented historical change.” Furthermore, while the National Assembly did not completely do away with the Old Regime censorship systems that it ostensibly abolished with the Declaration of the Rights of Man and Citizen, printers …

Assessing Non-Thermal Plasma In Cutaneous Regeneration, Arden Rodriguez, Meliah Martin, Graeme Grainger, Arineh Shahbazi

Discovery Day - Daytona Beach

Chronic and acute wounds remain a significant clinical challenge, particularly in austere and resource-limited environments where access to advanced care is restricted. Non-Thermal Plasma (NTP) has emerged as a promising, non-invasive modality with reported antimicrobial and regenerative properties; however, its mechanisms of action and effects on human skin tissue require further characterization. The scope of this project is to engineer and utilize a 3D human skin epithelial model to evaluate the effects of NTP on wound healing. We will first build a 3D epithelial tissue model that will simulate human skin, followed by modeling and evaluation of wound pathology and …

Extracting Aromatic Compounds From Dehydrated Rose Buds, Lana Sheridan

Discovery Day - Daytona Beach

Eugenol (C10H12O2), methyl eugenol (C11H14O2), and 2-phenylethanol (C8H10O) are chemically aromatic, natural compounds commonly present in various botanical sources and essential oils. Structurally, eugenol is a methoxyphenol bearing an allyl side chain; its methyl ether derivative, methyl eugenol, shares a similar framework but features a methoxy group replacing the free phenolic hydroxyl group found in eugenol. 2-Phenylethanol is an aromatic alcohol comprised of a benzene ring linked to an ethanol moiety. The objective of this project was to isolate and characterize these compounds in dried rose buds using distillation followed by chromatographic and spectrometric analysis. For the experiment, a steam …

Magnesium-Enhanced Methane: A Novel Metalized Fuel For Mars Return Missions And Next-Generation Propulsion Systems, Kinga Wysocka

Discovery Day - Daytona Beach

This research investigates magnesium-enhanced methane as a novel metalized fuel concept for high-performance, in-situ resource utilization (ISRU)-compatible rocket propulsion. While methane is a leading candidate for Mars missions due to its producibility via the Sabatier process, its combustion performance is limited by the high activation energy of the initial C–H bond (~4 eV). To address this limitation, density functional theory (DFT) calculations were performed to analyze methane and hydrogen interactions with a Mg(0001) surface. A converged slab model (3×3×4 and 3×3×5) was validated with energy differences below 1 meV per atom for k-point sampling and ~13.99 meV per atom for …

Advanced Manufacturing And Materials Of A Bio-Mimetic Hoof For Space Robotics Applications, Benjamin Heckel

Discovery Day - Daytona Beach

Planetary surfaces often feature steep, uneven, and unpredictable terrain conditions that resemble some of the most challenging natural environments on Earth. In these terrestrial settings, certain animals have evolved to navigate complex landscapes with remarkable agility. One example is the mountain goat, an animal whose hooves have evolved for stable and precise movement across rocky, inclined surfaces. This biological adaptation provides a useful model for improving robotic mobility in planetary exploration. This study draws inspiration from that natural adaptation to develop a bio-mimetic robotic hoof designed to enhance traction, durability, and adaptability for extraterrestrial exploration. By replicating the mechanical properties …

Experimental Design And Comparative Analysis Of Cubesat-Based Reflector Concepts For Future Solar Energy Redirection On Mars, Tatyana Vladislavova Ivanova

Discovery Day - Daytona Beach

Previous research shows that redirecting sunlight with large orbital mirrors could support warming specific regions of Mars by targeting ice deposits and releasing greenhouse gases. Although the concept has strong theoretical support, deploying and adjusting massive rigid reflectors in orbit remains a major technical challenge. This study aims to investigate the impact of using a swarm of small, adjustable CubeSats equipped with different reflector types on the effectiveness of solar energy redirection for Martian surface heating. Through comparison of multiple designs in controlled conditions, this work addresses whether smaller, flexible systems could offer a practical alternative to traditional large mirrors. …

Steam Distillation Star Anise, Makayla Maso, Kiara Maso

Discovery Day - Daytona Beach

Star anise (Illicium verum) contains several volatile organic compounds responsible for its characteristic aroma, including trans-anethole, estragole, limonene, and linalool. These compounds differ in structure and chemical properties, which influence their behavior during isolation and analysis. Trans-anethole and estragole are classified as aromatic phenylpropene derivatives that contain benzene rings and ether functionalities. In contrast, limonene and linalool are non-aromatic terpenes, with linalool additionally possessing an alcohol functional group. These compounds are widely utilized as flavoring agents and fragrance components, while terpenes such as limonene and linalool are also commonly employed as solvents and in formulation chemistry due to their volatility …

Se(3) Touchdown Dynamics With Multi-Joint Landing Legs And Regolith-Dependent Contact For Autonomous Tip-Over Risk Prediction, Rithika Nagarajan

Discovery Day - Daytona Beach

This project develops an SE(3)-based touchdown dynamics framework to study how lunar landers can remain stable during landing on sloped and uncertain terrain. Safe lunar landing is challenging because uneven load redistribution, slip, and asymmetric sinkage can push the vehicle’s center of mass outside its support polygon, increasing tip-over risk. The purpose of this work is to extend a fixed-leg touchdown model to a multi-joint landing leg system while also examining how varying regolith properties affect landing stability. The method combines coupled rigid-body translation and rotation with per-foot unilateral contact, compliant normal force response, and Coulomb-limited friction to simulate touchdown …

An Energy-Aware Meta-Learning Framework For Real-Time Lunar Rover Localization Via Adaptive Algorithm Selection, Jose Demedeiros, Garrett Seyler

Discovery Day - Daytona Beach

This work proposes an energy-aware meta-learning framework that selects the single most suitable localization algorithm for a lunar rover, per scene, using only monocular imagery and orbital maps. The goal is to achieve sub-meter accuracy while minimizing onboard compute and energy consumption. We assemble a suite of seven lunar-relevant algorithms spanning relative and absolute localization, including monocular ORB-SLAM3, LuVo homography-based visual odometry, Censible cross-view matching with orbital imagery, crater-based methods (LunarNav and ShadowNav), monocular horizon navigation with a DEM, and DROID-SLAM. Relative methods provide incremental motion updates, while absolute methods deliver global pose fixes; an Extended Kalman Filter fuses these …

A Qualitative Analysis Of Human-Ai Interaction Through Animated Shapes, Kavya Dipen Shah, Angel Hinojosa, Caroline Deck

Discovery Day - Daytona Beach

As technology becomes more advanced, it is important to understand how people perceive the intentions and abilities of machines. This project, conducted in the InTeRACT Lab, explores how we attribute humanlike qualities to different types of agents, ranging from animals to robots. The study analyzes data from an experiment where participants watched animations of moving triangles. Although the videos were identical, participants were told the shapes represented either humans, robots, dogs, or inanimate objects. While previous math-based data showed that these labels changed how people felt, those structured scales didn't allow for a natural, unbiased explanation of what people actually …

A System Safety Approach To Assuring Artificial Intelligence Enabled Functions In Civil Aviation, Evan Bear, Quinn Galen

Discovery Day - Daytona Beach

Artificial intelligence and machine learning techniques are increasingly proposed for use in safety-critical civil aviation functions including perception decision support and pilot assistance. Existing aviation safety and certification standards such as ARP4754A and DO-178C were developed under assumptions of determinism explicit requirements and complete behavioral specification which do not directly apply to learning-enabled systems. This mismatch has created uncertainty regarding how artificial intelligence enabled avionics can be safely assured and certified. This paper presents a system safety approach for assuring artificial intelligence enabled functions within existing aviation certification frameworks. In this approach safety assurance is based on explicitly identifying the …
