The Application Of Natural Language Processing Towards Auditing Of Unstructured Data: A Design Science Approach, Dennis K. Amoatey

Electronic Theses and Dissertations

Financial auditors must manually review large volumes of unstructured text that may include contracts, internal policies, footnotes, and journal entry descriptions. This time-intensive process introduces risk of human error and inconsistency. Despite advances in automation, no systematic approach exists for applying Natural Language Processing (NLP) to this problem at scale. Using a design science approach, this study develops a framework that demonstrates how NLP techniques can be incorporated across key phases in the audit process, including planning, internal controls evaluation, evidence gathering, and reporting. Initial evaluation through expert feedback had a mix of responses. While some argued difficulty with data …

Indiana Bat Population Dynamics In The Midst Of Climate Change And White-Nose Syndrome, Lexie Ann Schwartz

Theses

Climate change and emerging diseases are altering species distributions and ecosystem dynamics worldwide. For temperate insectivorous bats in North America, food availability and winter climate influence hibernation energetics and survival. As climate warming alters insect phenology, these changes are likely to have an impact on hibernating bats. Many cavernicolous bats in North America are also threatened by white-nose syndrome (WNS), a newly emerged fungal disease devastating bat populations. This study examined the distribution of hibernating Indiana bats (Myotis sodalis) over time throughout their range. I used long-term weather data to simulate seasonal insect availability, the spring and autumn transitory periods, …

Effects Of Androgens And Chronic Stress On Anxiety Related Behaviors And Stress Induced Neural Activity In Alzheimer’S Disease Mice, Mekenna Hobson

Psychology

Alzheimer's disease (AD) is a chronic neurodegenerative disorder that is characterized by a progressive decline in cognitive function. Neuropathologically, AD is shown as cortical intracellular neurofibrillary tangles (NFT) and extracellular β-amyloid (Aβ) plaques (Riverol & Lopez 2011) along with cerebral hypometabolism, neuroinflammation, and neuronal death (Armstrong et al. 2021). There are indications that early to mid-life stress has an impact on the risk of cognitive decline and plays a part in the pathology of the neurodegeneration that comes with AD (Armstrong et al. 2021). Psychological stress contributes to emotional states like depression and anxiety. It has been shown that people …

Perceptions On The Moral And Ethical Applications Of Generative Ai In Creative Game Development, Isabella Maccera

Emergency Preparedness, Homeland Security, and Cybersecurity

Advancements In Wall Systems For Cold Climate Timber Frame Structures, Albert Gérard

Architecture Theses

Timber frame buildings hold a privileged place in the homebuilding industry, where they are prized as a uniquely desirable construction method. Commonly cited reasons for their appeal are the way they feature natural materials and the prominent use of solid wood joinery. Although construction methods for the structures themselves were established through a series of seminal 1980s and 1990s English-language publications, the lack of a suitable wall system has continued to present challenges to achieving more widespread adoption.

From Tech To Table: Moving Sustainable Proteins Beyond Marketplace Bottlenecks, Andy Fitch, Cynthia Hanawalt

Sabin Center for Climate Change Law

Climate advocates may hope to see dramatic commercial breakthroughs over the next several decades that reshape emissions-intensive components of our everyday lives, such as our dietary choices, household energy use, and transportation habits. Yet transforming these consumer sectors will require not only scientific ingenuity and entrepreneurial ambition, but also nimble competition policy to address complex market dynamics.

Sustainable food production likely necessitates substantial departure from traditional livestock-management practices. Agricultural production currently generates about one-third of global greenhouse gas emissions (“GHGs”). Animal livestock account for the largest share, while occupying roughly 40% of the Earth’s habitable land, much of which could …

Hampton V. Maujer, Llc

All Decisions

The appeals court reversed the lower court's dismissal of an illegal lockout petition. The landlord had moved to dismiss based on a purported sublease, alleging the tenant had no rights to the apartment. However, the appeals court found it improper for the lower court to rely on the sublease because it was unauthenticated and not fully executed. Therefore, the documentary evidence did not, as a matter of law, demonstrate that the landlord and occupant did not enter the property by force or unlawful means, and dismissal of the petition was unwarranted. The petition was reinstated against both respondents.

Trust And Legitimacy In Police Public Encounters: An Analysis Of The 2018–2022 Police Public Contact Survey, Brooke Campbell

Masters Theses

This study examines how interaction-level characteristics in police-public interactions shape perceptions of trust and legitimacy. Using the Police Public Contact Survey (PPCS), interaction characteristics were investigated to see if they shaped perceptions of legitimacy and trust that the public has toward policing. Logistic Regression was used to see if factors such as contact duration, contact type, and time of day were associated with perceptions of police behavior, satisfaction, bias, future willingness to contact the police, and adequacy of the time spent. Drawing on legitimacy as the guiding framework, the PPCS years 2018, 2020, and 2022 (United States Bureau of Justice …

Extremum Seeking Compensation And Quantification Of Position Sensor Offset Error In Speed-Controlled Permanent Magnet Synchronous Motors, Tessa Biondo

Masters Theses

Position sensor offset errors present a persistent challenge in speed-controlled permanent magnet synchronous motor drives operating under field-oriented control. Even small, constant offsets in the measured rotor position can reduce torque effectiveness, requiring increased current and voltage demand to maintain the commanded speed and resulting in degraded speed regulation performance across a range of operating conditions. These effects are particularly problematic in speed-controlled systems, where speed loop dynamics cause increased electrical effort and limit overall performance. Many existing detection and compensation approaches are either dependent on the system model, require offline calibration, or are primarily designed for torque-controlled operation. This …

Transformer Vulnerability To Geomagnetically Induced Currents Using Layered Soil Conductivity Models, Junior A. Sterling

Masters Theses

Geomagnetically induced currents (GICs) pose a significant threat to modern power transformers connected to long high-voltage transmission systems, particularly in regions with low subsurface electrical conductivity. During geomagnetic disturbances (GMDs), time-varying magnetic fields induce surface electric fields that drive quasi-DC currents through grounded transformer neutrals. These currents can bias transformer cores, leading to saturation, waveform distortion, and potential system instability. Despite extensive research, the role of regional Earth conductivity in shaping electric fields and transformer response remains an area requiring deeper investigation.

This study analyzes how contrasting Earth conductivity profiles influence GIC magnitude and transformer saturation risk using two representative …

Conventional Vs. Regenerative Apple Orchard Management In Michigan, Anthony Poynter

Masters Theses

This study compares the variables and outcomes of a conventional apple orchard and a regenerative apple orchard production system in Kent County, Michigan. The premise is that conventional agriculture relies on high-input systems characterized by synthetic fertilizers, pesticides, herbicides, and fungicides, while regenerative agriculture focuses on long-term soil health, biodiversity, and ecological processes. These differences are important as soil degradation, nutrient loss, and environmental impacts are becoming too significant to ignore. Most research on alternative ways to farm, such as regenerative practices, is focused on annual crops, while perennial orchard systems, especially in the Great Lakes region, have gained limited …

Transient Mitigation In Dual Active Bridge Converter Using An Auxiliary Converter With High-Frequency Selective Control For Load Step-Down Condition, Sachith Dilshan Wijesooriya

Masters Theses

Dual Active Bridge (DAB) converters are widely utilized in applications such as electric vehicles, renewable energy systems, and solid-state transformers due to their high efficiency, galvanic isolation, and bidirectional power transfer capability. However, during rapid load transitions, DAB converters frequently exhibit significant output voltage overshoot and prolonged settling times, which increase device stress and adversely affect system reliability. This thesis proposes an auxiliary-circuit-based transient mitigation method to address these limitations. The auxiliary circuit, implemented as a bidirectional Buck–Boost stage, operates in Boost mode during load step-down events to absorb excess energy and suppress the resulting voltage overshoot. The design of …

Haunted By A Cheap Ghost: Objects As Identity, Caitlin Zachow

Masters Theses

I am haunted by a cheap ghost, surrounded by inherited memories that are not my own, preserved in heirlooms that leave little room for me to create souvenirs of my own experience. In response, my practice centers on the personal significance of collections as outward expressions of identity, personality, and lived experience. Rooted in themes of Midwestern Americana, this exhibition presents narrative tableaus and curated collections that examine how personal identity is constructed through objects of memory, and display.

Informed by research into the history of kitsch, Sigmund Freud’s concept of the uncanny, and the “outmoded,” my work considers how …

A Mixed-Methods Investigation Of Physician Compassion In Consultations For Chronic Primary Pain, Sarah Daehler

All Graduate Theses and Dissertations, Fall 2023 to Present

Chronic primary pain refers to physical pain that has no apparent organic cause, cannot be explained by another condition, and has associated psychological distress or functional impairment. Chronic primary pain is common and can significantly interfere with functioning, including occupational or social functioning. Research has shown that physicians struggle to treat this population, with many physicians reporting feeling unequipped and many patients feeling that their physicians are unhelpful and dismissive. Compassion may play a key role in improving these difficult interactions. The present study analyzed a sample of 99 participants with chronic pain and 100 healthy controls to learn more …

Effects Of Subsurface-Drip-Irrigation On Alfalfa Evapotranspiration In The Intermountain West, Namuna Dhakal

All Graduate Theses and Dissertations, Fall 2023 to Present

Alfalfa is one of Utah’s most important crops, but it is also the largest agricultural consumer of water. Because the state faces frequent droughts and growing pressure on limited water supplies, farmers and water managers are increasingly interested in irrigation systems that could reduce water use. Subsurface drip irrigation (SDI), which delivers water directly to plant roots through buried drip lines, has shown promising results in other regions, where it often reduces water consumption and increases yield. However, little research has evaluated SDI under Utah’s unique climate, soils, and high-elevation valleys.

This study compared an SDI system with a traditional …

Using national data from 2011 to 2021, the project analyzes enrollment and graduation patterns across institutions while accounting for differences in geography, governance, and state political context.

Rather than focusing on individual students, the study looks at institutional patterns. It examines how the racial and gender makeup …

Counterfactual Explanations For Time Series Through Local Pattern Mining And Generative Models, Omar Bahri

All Graduate Theses and Dissertations, Fall 2023 to Present

Machine learning systems increasingly make decisions that affect people’s lives, from medical diagnoses to loan approvals. When these systems analyze time series data—sequences of measurements collected over time, such as heart rhythms or sensor readings—users need to understand why a particular prediction was made. Counterfactual explanations address this need by answering “what-if” questions: what would need to change in the input for the system to make a different prediction? 

This dissertation develops methods for generating counterfactual explanations specifically designed for time series data. Time series often contain distinctive local patterns—short subsequences that distinguish one class from another. For example, a …
