Abnormalities In Sensorimotor Brain Function Are Related To Chronicity Of Low Back Pain, Jo Armour Smith, Rongwen Tain, Kelli G Sharp, Laura M Glynn, Linda R Van Dillen, Jesse V Jacobs, Steven C Cramer

2020-Current year OA Pubs

Maladaptive plasticity in the brain may contribute to chronic low back pain (LBP) and underlie the altered postural control of the lumbopelvic musculature that is evident in some individuals with LBP. We recently described an MRI-compatible leg-raise paradigm to measure brain activity associated with lumbopelvic postural control. The objective of this study was to compare brain function in young adults with and without a history of LBP and to determine relationships between brain function, pain, and postural control characteristics. We recruited 55 participants with a history of LBP, who were asymptomatic when studied, and 30 healthy controls. Postural control during …

¡Salud! Sacrificing The Sacred Sip: A Critical Analysis Of The Impact Of The Spiritual Conquest On Alcohol Traditions In Central México, Elizabeth Vilchis

Graduate Theses/Dissertations

By thoroughly investigating the available primary sources, this thesis will convey the importance of the Mesoamerican inebriating drink pulque in both the ethos and mythos of ancient Nahua society, examining how the ritual use of pulque became problematic in the eyes of the Spaniards, by investigating the cultural and ideological contradictions or double standards that enabled the tensions, struggles, and violence with which the Spanish colonial regime repressed the ritual use of pulque. This thesis compares the Nahua ethos and mythos of pulque to the Christian ethos and mythos of wine, highlighting the parallels perceived by Spaniards in Central México …

Drone Dichotomy: Investigating The Application Of Unmanned Aerial Systems For Offensive And Defensive Chemical, Biological, Radiological, And Nuclear-Related Tasks, Evan Jacob Martinovitch

Graduate Theses/Dissertations

This thesis investigates the application of unmanned aerial systems (UAS) for both offensive and defensive chemical, biological, radiological, and nuclear (CBRN) tasks to determine if they serve as a force multiplier on the modern battlefield. As CBRN weapons reemerge as realistic threats alongside the rapid proliferation of UAS, the intersection of these fields presents unique challenges and opportunities. Through a methodology that examines the history of the UAS-CBRN intersection, military doctrine, and the status of UAS technology, this research evaluates the capability of current and emerging UAS against specific CBRN delivery, reconnaissance and surveillance, and decontamination tasks. The analysis conducted …

Nonbinary Gender Performance And Self-Identification In Mary Shelley's Frankenstein, Lillian R. Durr

Graduate Theses/Dissertations

Mary Shelley’s 1818 novel Frankenstein, a text informed by a rich Romantic era philosophical tradition, has produced an expansive contemporary body of transgender studies scholarship. Building on transgender literary studies of Frankenstein, my thesis analyzes the difference between the monster’s internalized self-perceived identity and their externally performed and perceived identity. I interpret the difference between the monster’s internal and external identity as an analogy through which to understand contemporary nonbinary experiences. The “performance” of gender that Judith Butler describes is a limited expression of an internal, inescapable, ontological experience of self-identification. The monster’s own social experience illustrates the …

The Confidence-Man Goes To The Moving Panorama: Herman Melville’S Confidence Narrator And United States Imperialism, Bradley J. Lee

Graduate Theses/Dissertations

This thesis argues that Herman Melville fashioned his novel The Confidence-Man; His Masquerade (1857) after the moving panorama, a popular entertainment technology contemporary with the novel. More specifically, the thesis argues that the novel recalls Banvard’s Mississippi Panorama (1846). Using Jay Leyda’s The Melville Log and John Hanners’ record of Banvard’s performances, I establish beyond reasonable doubt the possibility that Melville saw this painting, or, at the very least, was aware of it, its content, and its social position. Tracing the novel’s engagement with this panorama reveals what seems at first to be its imperialist, Manifest Destinarian undertones. The novel’s …

Northern Luzon In A Taiwan Flashpoint: The Philippines’ Place In U.S. Strategy, Carson Keller

Graduate Theses/Dissertations

While the defense of Taiwan from a potential invasion by the People’s Republic of China (PRC) has long been a topic of debate and scrutiny in U.S. strategic thinking, the role of its southern neighbor, the Philippines, has received far less attention. This thesis argues that northern Luzon would constitute key terrain in a cross-strait conflict and may become an early target of People’s Liberation Army (PLA) operations. Its proximity to Taiwan and position along the Luzon Strait, particularly the Bashi Channel, places it at the center of efforts to control access to the hypothetical battlespace. Drawing on PLA and …

Inherited Sins: Essays, Claire Ellerman

Graduate Theses/Dissertations

Joan Didion said of her book, The Year of Magical Thinking, that, “the reason I had to write it down, is that no one had ever told me what it was like.” She was trying to make sense of her grief following the death of her husband, and in doing so, wrote a piece of creative nonfiction (CNF) that explores her own life in and around the larger ideas of mourning, connection, and moving forward. This is the ultimate aim of creative nonfiction: writing to make sense of our lives in relation to the world around us. In this …

Gene Editing And The Accessibility Of Bioterrorism: Rethinking Global Biosecurity In The Post-Covid-19 Era, Nicholas Morales

Graduate Theses/Dissertations

COVID‑19 demonstrated how a single biological event can strain health systems, disrupt supply chains, undermine national security, and erode public trust. This shock occurred as biotechnology became dramatically more accessible: gene editing and synthetic biology tools once limited to specialized laboratories are now widely available through inexpensive equipment, open‑source data, and decentralized expertise.

This expanded access accelerates innovation but also broadens the threat landscape. The ability to reconstruct pathogens using publicly available sequences and mail‑order DNA shows that complex biological synthesis is no longer confined to state programs. These risks are amplified by opaque biotechnology activities in China, Russia, and …

Using 1:1 Behavior-Analytic Instruction To Enhance Outcomes Of A Social-Emotional Learning Curriculum: A Retrospective Single-Case Clinical Evaluation, Cierra Vandermeer

Graduate Theses/Dissertations

Social-Emotional Learning (SEL) is the process through which people acquire and apply skills to manage emotions, form relationships, make responsible decisions, and pursue personal and shared goals, and these competencies shape identity development and daily functioning (Collaborative for Academic, Social, and Emotional Learning [CASEL], 2020). While there are many SEL programs and curricula that exist for school-aged children, there are few curricula that a) have a focus on 1:1 instruction for preschool to primary-aged children, and b) integrate and incorporate Applied Behavior Analysis (ABA) principles. This thesis reviewed a retrospective case study of a six-year-old female-identifying student who participated in …

Eastern Fox Squirrel (Sciurus Niger) Occupancy In A Southern Missouri Woodland, Daniel Garten

Graduate Theses/Dissertations

Species occupancy, which relates the probability of presence of a species at a specific place and time, is an important component of conservation and wildlife management. Principally it is used for estimation of a species’ distribution as well as understanding species interactions and quantifying environmental effects. The purpose of this study was to analyze occupancy of the Eastern Fox Squirrel (Sciurus niger) across multiple seasons (2019–2022) at Bull Shoals Field Station (BSFS), and to identify potential covariates associated with detection and colonization. Data were drawn from camera trap surveys from 26 sites during summer and fall seasons. Multi-season occupancy models …

When Speech Speaks Louder Than Truth: Language Variation And Credibility In The Courtroom, Melanie E. Spinnie

Graduate Theses/Dissertations

This study aims to investigate how linguistic variation affects perceptions of credibility in courtroom settings. It focuses on how jurors, judges, and other individuals in the legal system may exhibit bias (consciously or unconsciously) based on how a defendant or witness speaks-- this could include speech disorders as well as differences in dialect, accent, and speech style. Through review of relevant literature, review of a relevant historical case, conducting a survey, and conducting a semi-structured interview, this study explores whether certain speech patterns or characteristics are disproportionately associated with negative judgments during legal proceedings, such as reduced credibility and trustworthiness. …

Europe In The Indo-Pacific - Implications For The United States, Joshua G. Zinicola

Graduate Theses/Dissertations

Within the last five years the Indo-Pacific has become a region of increasing interest to European NATO members. In particular, the United Kingdom, France, and Italy have assigned strategic importance for their national security to the region, signing cooperative agreements with regional allies of the United States and deploying significant forces to the region. These agreements include commitments to jointly develop new technologies and combat systems for employment in both Europe and the Indo-Pacific, such as the Global Combat Air Programme (GCAP), and the Trilateral security partnership between Australia, the United Kingdom, and the United States (AUKUS). They also include …

A Geospatial Assessment Of Groundwater Salinization In A Multi-Aquifer System: Durango, Mexico, Juan Lopez-Sierra

Graduate Theses/Dissertations

Groundwater salinization poses a critical environmental concern for water resource sustainability in arid and semi-arid regions. This study evaluates spatial and temporal patterns of groundwater salinity across the state of Durango, Mexico, using total dissolved solids (TDS), sodium adsorption ratio (SAR), as salinity indicators and nitrate-nitrogen (NO₃–N) as an anthropogenic indicator. Groundwater quality data were obtained from (CONAGUA), a Mexican water agency. To assess salinity variations with respect to time, while minimizing interannual sampling bias, two multi-year sampling periods were selected: 2012-2013, and 2020-2021. Final datasets consisted of 122 wells for 2012–2013 and 131 wells for 2020–2021. The wells were …

Stopping The Buck: What Made The Truman Committee Uniquely Successful In Its Oversight Of World War Two Military Contracts, Victoria Kelley-Chiarelli

Graduate Theses/Dissertations

During World War Two, Harry S. Truman led the Senate Select Committee to Investigate the National Defense Program, also known as the Truman Committee, in its oversight of military contracts and the war effort. The Truman Committee saved the U.S. government billions by identifying and discouraging waste, fraud, and abuse, and saved many armed forces personnel’s lives through identifying defective products. Truman’s background in World War One service and his time as a local official in Missouri show signs of the integrity and commitment to good governance that made the Truman Committee so successful. The Truman Committee’s membership, staff, principles, …

Exploring Factors Mediating White-Nose Syndrome In Little Brown Bats, Carly R. Trujillo

Graduate Theses/Dissertations

The little brown bat (Myotis lucifugus) has experienced drastic population declines across North America due to the recent disease white-nose syndrome (WNS). Previous studies have identified putatively adaptive alleles (PAAs) that may give individuals a greater likelihood of survival. However, there could be geographic-specific adaptation, creating different adaptive landscapes. Additionally, there may be energetic trade-offs between disease survival and reproductive output, and it is not clear what the long-term survival outcomes for the species may be as a result. Long-term evolutionary outcomes are unclear because this species has a lifespan exceeding the arrival of WNS and is difficult …

31p Solution Nmr Investigation Of Abasic Dna, Clarissa R. Krimmel

Graduate Theses/Dissertations

Base excision repair (BER) mechanisms fix single base lesions in DNA, such as T:G mismatches. During the base excision repair mechanism, an abasic site (AP site) is formed as an intermediate. AP sites are unstable and highly mutagenic; they can stop DNA replication. This research investigates how the conformational properties of abasic sites in DNA affect the binding recognition of enzymes involved in DNA repair mechanisms, including BER. Three different abasic sequences are being analyzed for this research project. A second project looks at the effects of a naturally occurring purine derivative, hypoxanthine, on the DNA backbone. These hypoxanthine lesions …

Corpus Meum, Mea Electio, Kara L. Coonrod

Graduate Theses/Dissertations

The right to bodily autonomy and reproductive freedom is something I hold very close to my heart. Women who did not wish to embrace motherhood, or who grew beyond the walls of the hearth and home, have been far more often persecuted than praised. Over the past two years, I have created artwork borrowing the visual and material language of the Catholic church (along with personally relevant folklore) to elevate my freedom of choice and bodily autonomy in the face of religiously driven political oppression. Using a less frequently referenced organ from my reproductive system to represent my struggle against …

Herp Count 2025, Camryn Gulledge

Graduate Theses/Dissertations

Herp Count 2025 is a process-based project in which I log and document every herp (reptile or amphibian) I encounter in the wild while investigating the realities of human impact on ecosystems. During 2025, I observed 1,406 individual herps, most of which appeared not in remote wilderness but in the compromised margins of human spaces. When I observe them in a littered area, I collect nearby trash and bring it back to my studio to combine it with a detailed drawing of that specific individual. In my Contact series, I use a clean-touch printmaking process that involves a stretched plastic …

Heterogeneous Robots Cooperation Via Multi-Agent Reinforcement Learning, Rehab Uddin Shawon

Graduate Theses/Dissertations

Enabling heterogeneous robots with diverse capabilities, roles, and task responsibilities to coordinate effectively in complex, dynamic environments remains a fundamental challenge in autonomous multi-robot systems. Multi-Agent Reinforcement Learning (MARL) provides a promising framework for decentralized cooperation. However, most existing MARL approaches assume homogeneous agents or fixed single-task settings and suffer significant performance degradation as the number of robot and task types increases. This thesis presents a scalable shared-policy MARL framework that allows heterogeneous robots to learn specialized behaviors for individual, sequential, and collaborative tasks involving temporal and spatial dependencies through a single neural policy. I first embed robot identity directly …

The Effect Of Sex On A-To-I Editing In Skeletal Muscle During Inflammation, Skyler Lee

Graduate Theses/Dissertations

Adenosine-to-inosine (A-to-I) RNA editing is a post-transcriptional mechanism mediated by ADAR enzymes that can alter RNA sequence, protein function, and gene regulation. Because ADAR1 is upregulated during inflammation and plays a critical role in innate immunity, previous studies investigated the effects of acute inflammation on RNA editing in male and female mice. Lipopolysaccharide (LPS) was used to induce inflammation, and RNA editing levels were examined in the heart, brain, and skeletal muscle. While editing levels in the heart and brain remained unchanged, skeletal muscle exhibited tissue- and sex-specific differences in editing. In this thesis, LPS treatment affected selective editing, increasing …

Climate Change In Gilgit-Baltistan: Satellite-Based Land Use/Land Cover Change Detection, Socio-Economic Dimensions, And Adaptation Strategies, Ali Muhammad

Graduate Theses/Dissertations

Climate change is increasingly transforming the cryosphere, hydrology, and human landscape of Gilgit-Baltistan, a highly climate-sensitive mountain region in northern Pakistan. This thesis investigates these transformations through satellite-based land use/land cover (LULC) change detection in four representative tehsils of Gilgit-Baltistan—Ali Abad, Gilgit, Nagar, and Sikander Abad—selected to span a gradient of human pressure and cryospheric exposure within the region. Using summer, cloud-free (< 10%) imagery from USGS Landsat 7 (2000) and Landsat 8 (2025), it conducts a multi-temporal comparison of environmental and socio-spatial change. After atmospheric correction and band compositing, the imagery is classified in ArcGIS Pro into six classes—Water, Barren land, Vegetation, Snow, Glacier, and Built-up—using a Support Vector Machine (SVM) classifier, with Maximum Likelihood Classification and Random Forest also tested but found less suitable for the final workflow. The analysis detects a pronounced reduction in mapped glacier-class area alongside a comparatively stable snow class, together with built-up expansion, while examining how temperature, precipitation, tourism, and population dynamics relate to observed LULC transitions. The results reveal a pattern of cryospheric decline and urban growth, with implications for water availability, ecological stability, hazard exposure, and settlement pressure. By integrating geospatial change detection with climatic and socio-economic interpretation, the thesis moves beyond mapping to explain interacting environmental and human drivers of landscape transformation and provides a reproducible remote-sensing baseline for monitoring land-surface change in heterogeneous mountainous terrain. It recommends integrated water-resource management, climate-resilient land-use planning, watershed and glacier monitoring, and sustainable tourism governance, supporting evidence-based decision-making by the Government of Gilgit-Baltistan and organizations working on climate adaptation, disaster risk reduction, and sustainable regional development.

Flood-Regime Shifts Across The Lower Midwest, Usa: Identifying Patterns Through Flood Magnitude–Frequency Analysis And Clustering, Kaiser Mostafiz

Graduate Theses/Dissertations

Flood regimes describe how flood behavior changes in magnitude, recurrence, and occurrence through time. Changes in these flood characteristics can affect flood hazards, river systems, infrastructure, and floodplain management. This thesis examines flood-regime change across the Lower Midwest, focusing on Nebraska, Iowa, Kansas, and Missouri from 1961 to 2020. Records from 1,452 U.S. Geological Survey gaging stations were initially compiled, and 208 stations were retained after screening for record availability and analytical consistency. Flood-regime change was evaluated between two 30-year study periods: Period 1 (1961–1990) and Period 2 (1991–2020). The analysis combined Log-Pearson Type III flood-frequency analysis using L-moments in …

American Elderberry's Next Top Pollinator: Evaluating The Role Of Arthropods In Pollination, Jenny K. Burrow

Graduate Theses/Dissertations

American elderberry (Sambucus nigra subsp. canadensis) is a woody deciduous shrub native to eastern North America. In addition to its long history of use by indigenous peoples, there is renewed interest in cultivating and consuming American elderberry, primarily driven by expanding health supplement markets. Despite recent advances in horticultural development of American elderberry, its pollination ecology remains poorly understood. In this field study, I evaluated the contribution of arthropod visitors to pollination of American elderberry. To do this, I first characterized the identities and abundances of arthropod visitors via timed arthropod collections and floral observations during peak flowering …

Advancing Hate Speech Detection: Binary And Multiclass Approaches From Traditional Methods To Parameter-Efficient And Ontology-Guided Language Models, Mahmoud Abusaqer

Graduate Theses/Dissertations

The widespread proliferation of hate speech on social media platforms poses significant challenges for content moderation and user safety, requiring automated systems that are simultaneously accurate, efficient, and capable of fine-grained distinctions. This thesis investigates hate speech detection through five published manuscripts organized into two complementary threads: binary detection (hateful vs. non-hateful) and multiclass detection across demographic targeting categories. The binary thread progresses from a broad 38-model baseline spanning traditional machine learning, deep learning, and transformer architectures (where RoBERTa reaches 91.48% accuracy and CatBoost remains competitive at 88.60%) to parameter-efficient adaptation, in which Low-Rank Adaptation (LoRA) of large language models …
