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. …

Spatial Patterns And Morphometric Evolution Of Sinkholes In Response To Watershed Hydrogeomorphology: Examples From A Karst Landscape In The Missouri Ozarks, Usa, Marcell Tóth

Graduate Theses/Dissertations

Sinkholes are characteristic enclosed depressions with internal drainage connecting the surface and subsurface karst hydrologic system. Their morphological evolution involves gradual subsidence of the ground surface and hazardous collapses. Therefore, understanding sinkhole morphometry and linked spatial distribution is critical for managing geohazards in karst watersheds. Sinkhole occurrence shows spatial variability based on watershed geomorphological attributes, surficial hydrological patterns, hydrogeological and geological settings. The aim of this research is to investigate morphometric properties and distribution of sinkholes in the carbonate karst-dominated lands of Mark Twain National Forest in Missouri, USA. The specific objectives were to (1) identify sinkhole clusters based on …

Experimental Diegetic Thresholds: A Study Of Adapted Carceral Narratives [The] Nickel Boys And Sing Sing, Leslie D. Muench

Graduate Theses/Dissertations

The diegesis is the storyworld of a film, including all the characters, settings, events, and other elements. At certain times, though, that threshold is permeable, particularly when the fictional source material involves lived experiences. Two carceral films model an experimentation with adapted material and the palimpsestuous layering effect that is a result of real-life narratives being transposed into fictional ones. Nickel Boys, directed by RaMell Ross (2024), and Sing Sing, directed by Greg Kwedar (2023), endeavor to humanize a stereotypically ostracized community: Black boys and men who are incarcerated. Through the screenwriting, casting, producing, filming, and sharing of their films …

Confucian Thought As A Strategic Veil: How Western Strategy Should Correctly Compete With China, Owen Miller

Graduate Theses/Dissertations

The rise of the People's Republic of China as a peer competitor to the United States constitutes the defining geopolitical challenge of the twenty-first century, but even so, Western strategic analysis has consistently failed to engage China on its own terms. The recurrent pattern of Western misinterpretation results from projecting Western assumptions onto a state whose institutional and cultural drivers operate under fundamentally different premises, where key elements of Chinese strategic culture and the Chinese Communist Party’s (CCP) instrumentalization of Confucianism as a moral veil are instruments of domestic legitimacy and external strategic narrative. The United States must recognize that …

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 …

The Ones Who Watched: Technology, Proxy Warfare, And The Testing Ground Hypothesis, Sean J. Oliver

Graduate Theses/Dissertations

Great powers need laboratories for war. This thesis argues that great powers find these laboratories in proxy forces. Proxy warfare is not just a tool for strategic influence. It is a machine for experimentation. This study posits a central testing-ground hypothesis. It contends that great powers deliberately use surrogates to vet emerging technologies, doctrines, and mobilization schemes under the pressure of real combat. The analytical methodology is historical. It traces patterns from the ancient world's proxy forces and the innovations of the Crusades to the Cold War and the digital age. The thesis examines enduring patterns, including the tension between …

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, …

The Room That Remembers: A Sanctuary Built From Silence, Kayla Brown

Graduate Theses/Dissertations

This installation is a process-based paper artwork that seeks to protect, enlighten, and discover what healing can be in silence. Through the creation of immersive art objects and experiences, I seek understanding and resolutions for my lived experiences. I utilize the physicality of paper in conjunction with the fragility of topic to enhance the meaning behind my material choices. I transform the idea of a traumatic room into an activated space of healing: one that rest, time, and momentary silence exist as choice rather than by force.

Twelve Preludes, Sarah Miller-Ross

Graduate Theses/Dissertations

This set of 12 Preludes for solo piano draws inspiration from Chopin’s set of 24 Preludes for the same instrument, along with ideas from other composers and various genres to create a varied set in which each piece is centered around a note of the 12-note chromatic scale. The movements are titled based on the material that inspired them, the effect they create, or the special technique or limitation they used. A brief overview of inspirational material will be discussed, then each movement will be described through the lens of their compositional processes.

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 …

The United States' Nuclear Deterrent Outlook: Strategies, Challenges, And Future Prospects, Jonathon L. Beening

Graduate Theses/Dissertations

This study contends that the United States cannot sustain a credible nuclear deterrent through the mid-21st century without modernizing its aging nuclear arsenal and revising its nuclear doctrine to address emerging technological, geopolitical, and strategic threats posed by both near-peer adversaries and non-state actors. Through an examination of deterrence theory, historical developments, current force posture, modernization initiatives, doctrinal debates, counterarguments, and prospective geopolitical scenarios, this research assesses the adequacy of existing policies in maintaining strategic stability. The analysis concludes that credible deterrence in the coming decades will require integrated modernization, doctrinal clarity, and strategic adaptability to face any future threat …

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 …

Remediation Impacts Metal Concentrations And Metal Tolerant Bacteria In Soils Of The Missouri Tri-State Mining District, Ophelia R. Pettington

Graduate Theses/Dissertations

After over 100 years of Zn and Pb mining in the Tri-State mining district (TSMD), former mines continue to be sources of metals. Metal contaminated soils can be remediated using plant-microbe interactions. Plants manipulate their microbiome and recruit microbes to increase metal tolerance. Remediating bacteria are site-specific and identifying native microbes can accelerate remediation efforts. Studies relating microbes and metal concentrations in remediated areas in the TSMD are scarce. I collected root and bulk zone soils associated with Andropogon virginicus from remediated and non-remediated sites in Webb City, MO. I used 16S rRNA gene amplicon sequencing to evaluate the bacterial …

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.

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 …

Engaging Elementary Music Students Through Multisensory Teaching In A Kodály-Inspired Classroom, Chelsea Taylor

Graduate Theses/Dissertations

Multisensory teaching is an instructional approach that is increasingly implemented in general education classrooms. Although it has been widely studied in special education settings and in the teaching of reading skills, it has not been extensively examined within music education. The purpose of this study was to examine the impact of multisensory instruction on student engagement, comprehension, and retention of concepts in my elementary music classroom. Through Kodály-inspired lessons that challenged students to audiate pitches while kinesthetically building a pentatonic scale, notate music on textured surfaces, and play games that incorporated simultaneous sensory input, these lessons intentionally integrated visual, auditory, …

Development And Validation Of The Ipip-Ocean: A Hierarchical Facet-Level Measure Of The Big Five, Caleb Niccum

Graduate Theses/Dissertations

This study focused on developing a mid-range, hierarchical, five-factor, 20-facet personality inventory (the IPIP-OCEAN) composed of 100 items drawn from both the IPIP-NEO-300 and the Abridged Big Five Circumplex. Hierarchical confirmatory factor analysis was used to validate the factor structure. Depression and anxiety, measured with the PHQ-9 and GAD-7, were used to further validate the measure through discriminant and convergent validity by examining whether the domains and facets of the IPIP-OCEAN produced findings consistent with those reported for similar scales in prior depression and anxiety research. Numerous factor analyses were conducted on the IPIP-OCEAN dataset (N = 1,058), and a …

Synthesis And Characterization Of The New G3 Family Of Organoantimony(V) Cyanoximates, Thao Trang Phan

Graduate Theses/Dissertations

Bacterial infections pose a serious threat to humans by developing resistance, rendering antibiotics ineffective. Of the 12 antibiotics recently approved since 2017, 10 belong to an already existing class. Various resistance mechanisms, such as reduced drug uptake, active efflux, drug inactivation, and target modification, can significantly reduce the efficacy of entire classes of antibiotics. Discovering novel strategies to overcome diverse mechanisms of resistance and improve therapeutic efficacy is in high demand. Inorganic compounds with organic ligands (both complexes and organometallics) represent a new class of compounds against which antimicrobial resistance has not yet been established. Recently, we discovered two series …

In The Beginning There Was Positive Law: Section 25, Calder V. Bull, And Constitutional Continuity, Kevin C. Walsh

Scholarly Articles

From the beginning of its operation as fundamental law for the government of the United States, the Constitution has continually operated as supreme and judicially enforceable positive law. This is the principal claim I offer as an “original-law originalist” in response to contrary claims advanced by Professor Jonathan Gienapp in Against Constitutional Originalism: A Historical Critique. Gienapp argues in Against Constitutional Originalism that “[h]istoricizing the original Constitution . . . poses a foundational challenge to originalism as it has long been conceived.”2 Constitutional originalism depends on perceived continuity with the past. But the perception of constitutional continuity turns out to …

The Pedagogy Of Legal Synthesis, Stephen Mortellaro

Scholarly Articles

The ability to synthesize implicit legal principles from many ambiguous cases is a mark of a skilled attorney. But legal synthesis is notoriously challenging to teach, and law students typically receive little explicit guidance on how to synthesize. The literature likewise offers law professors little direction on how to impart the skill successfully. This Article serves as a guide for professors to effectively train law students to synthesize implicit legal principles. Drawing upon cognitive science, the study of logic, and educational research, this Article explains the challenges of learning legal synthesis and equips professors with pedagogical methods and curricular resources …

Bracing The Wobbly “Three-Legged Stool” By Increasing Homeownership Opportunities For Low- And Middle-Income Workers, Regina T. Jefferson

Scholarly Articles

Traditionally, the primary sources of retirement income were personal savings, the private retirement system, and Social Security. These three sources have been described metaphorically as the “three-legged stool” of retirement security. In this framework, each leg was viewed as a separate and distinct source of income that provided support throughout a worker’s retirement. Each source presented different and varying degrees of risks that were pooled collectively among the individual, the employer, and the government. Each source also functioned independently of the other two. Thus, the traditional framework of retirement income was thought to be ideal because it balanced and diversified …

Laudato Si' And The Limits Of Law: Reflections On The Vocation To Protect Integral Ecology, Lucia A. Silecchia

Scholarly Articles

In 2015, Pope Francis’s widely anticipated encyclical, Laudato Si’: On Care for Our Common Home, was released. It was a wide-ranging commentary on the state of the world, with much to say to economists, ecologists, farmers, theologians, educators, architects, artists, and pastors. It may, however, have been of particular interest to lawyers eager to see what Pope Francis had to say about law’s particular role. 

On this question, Laudato Si’ painted an inconsistent portrait of law’s suitability to this task. Pope Francis spoke passionately about the need for law at all levels to tackle the complexities of caring for our …

The Genius Dilemma: Innovation Versus Antifraud In Stablecoin Regulation, Seth C. Oranburg

Scholarly Articles

The 2022 TerraUSD collapse, erasing $50 billion and exposing unregulated stablecoin risks in a $260 billion market, led Congress to enact the Guiding and Establishing National Innovation for U.S. Stablecoins Act of 2025 (GENIUS Act). This statute exempts compliant payment stablecoins from the Securities Act's "security" definition, enforces strict reserve requirements, and creates a tailored private right of action-shifting authority from ex post Rule lob-5 litigation to ex ante prudential oversight while maintaining market discipline via calibrated remedies.

As the first doctrinal analysis of this landmark legislation, this Article contends GENIUS resolves regulatory fragmentation, optimizes risk allocation under uncertainty, and …

Strict Scrutiny And The Viewpoint Continuum, A.G. Harmon

Scholarly Articles

Consider the following instances: A cell phone photograph picturing a man's left kneecap. A statement that the speaker thinks, "The name Josiah is really cool." A woman who runs her bicycle over a business owner in order to gain celebrity and increase attention for her new podcast. An intentional lie told to acquire a job. A student who insists on answering his math exam questions in runic symbols.

At one point or another, American courts have considered the merits found in favor of instances similar to these and other like circumstances as amounting to "viewpoints." As such, they …
