Accuracy Of Voluntary Force Modulation During The Isometric Mid-Thigh Pull, S. Alexander Long, Olivia Vadas, Stephanie Balint, Michael H. Stone, Christopher Taber

Exercise Science Faculty Publications

The purpose of this study was to investigate voluntary force modulation accuracy during the isometric mid-thigh pull (IMTP) and to investigate biological sex and relative strength as factors relating to error. Strength-trained males (n = 18) and females (n = 18) completed ascending (ASC) (25%, 50%, 75%) or descending (DESC) (75%, 50%, 25%) submaximal testing followed by maximal testing. Subjects rested before completing the opposite submaximal testing sequence. External feedback was not provided during testing. Measured and intended (INT) forces were analyzed with two-way repeated-measures ANOVAs with within- (ASC, DESC, and INT) and between-subject factors (male or female). Independent-samples t-tests …

A Test Of The Three-Step Theory: Examining Pain, Hopelessness, And Suicidal Desire Among College Students, Shelby Baker

Graduate Studies Theses and Dissertations 2026

Suicide is a leading cause of death, and suicidal thoughts are prevalent among emerging adults and undergraduate students. Still, many prominent risk factors remain understudied. Guided by the Three-Step Theory of Suicide (3ST), this study examined the roles of hopelessness, psychological pain, and physical pain in prediction of suicidal desire among undergraduate college students (N = 1,705) recruited from UCF’s SONA system and CloudResearch’s Connect platform. Participants completed an online, cross-sectional survey that included measures of suicidal thoughts and behaviors, hopelessness, psychological pain, physical pain, and other psychological variables of interest. Psychological pain and physical pain were tested as moderators …

Investigating Effects Of The Macroalga Caulerpa Prolifera On Restoration Of The Seagrass Halodule Wrightii In The Indian River Lagoon, Florida, Luciana M. Banquero

Graduate Studies Theses and Dissertations 2026

Seagrass restoration efforts have been motivated by global decreases in coverage associated with anthropogenic influences on the environment. In the Indian River Lagoon (IRL), FL, seagrass declined by 75% between 2011 and 2021. During this time, abundance of the macroalga Caulerpa prolifera increased substantially in the IRL. The macroalga is native to this estuary, however C. prolifera abundance has fluctuated widely in the past few decades. Being highly opportunistic, C. prolifera took advantage of areas formerly inhabited by seagrass. It is not known how dense, continuous beds of C. prolifera impact seagrass restoration projects or natural recovery of seagrass. Previous …

A Reconstruction Method For The Anisotropic Electrical Conductivity In A Hybrid Planar Inverse Problem, Athanasios Dimitriadis

Graduate Studies Theses and Dissertations 2026

Some single-physics medical imaging methods fail to reliably discriminate benign from malignant biological tissue. In partial response, a new class of inverse problems employ multi-physics phenomena, coupling methods of high resolution with methods of high contrast. In this thesis we are concerned with one such problem in which an anisotropic electrical conductivity is to be recovered from some internal knowledge of the current density field generated by maintaining a fixed boundary voltage. This internal data is obtained by the method of Current Density Impedance Imaging (CDII), which combines Maxwell's equations with Magnetic Resonance Imaging (MRI) measurements. The anisotropy class is …

Benchmarking And Advancing Heterogeneous Data Reasoning With Large Language Models, Yebowen Hu

Graduate Studies Theses and Dissertations 2026

Large language models (LLMs) increasingly face complex real-world tasks requiring complex reasoning over heterogeneous inputs, including text, numbers, and structured data. This dissertation first investigates the capability boundaries of LLMs under such scenarios. Through the MeetingBank and SportsMetrics benchmarks, we show that while LLMs exhibit linguistic fluency, they struggle with factual accuracy, information density, and quantitative cross-referencing in meeting summarization and sports analysis. Using DecipherPref, a pair-wise evaluation framework grounded in the Bradley-Terry-Luce model, we further probe LLMs' inherent preferences for information-rich and lengthy inputs, and we identify critical deficiencies in financial decision-making through DeFine, where models lack precise insight …

Viral Dynamics Across Managed And Wild Pollinators: Integrating Immunity, Ecology, And Community Structure, Allison Malay

Graduate Studies Theses and Dissertations 2026

Managed honey bees (Apis mellifera) are critical agricultural pollinators, yet colonies continue to experience persistently high losses across North America and Europe. These declines are driven by interacting stressors, including parasites, pathogens, nutrition, and landscape context. Viral pathogens are key contributors to colony morbidity and mortality, but the processes governing variation in viral prevalence, load, and host response remain incompletely understood. This dissertation investigates how viral dynamics in honey bees emerge from interactions among host immunity, colony condition, environmental context, and pollinator community structure. By integrating measures of viral prevalence, viral load, and immune gene expression across multiple …

Quantifying The Effects Of Anthropogenic Disturbance On Two Marine Mammal Species With Agent-Based Models, Landon S. Myers

Graduate Studies Theses and Dissertations 2026

This dissertation details the construction and results from two agent-based models (ABMs) that quantify the effects of anthropogenic disturbance on very different marine mammals.  Most would agree the anthropogenic effects on animals are “bad”; the unknown is “how bad.”  Chapter 1 describes the ABM assessing the mortality risk from seagrass loss and the potential loss of a warm water refuge on manatees living in Florida ‘s Indian River Lagoon (IRL).  IRL manatees are at the northern habitat limit and susceptible to hypothermic mortality, and utilize natural and artificial warm water refuges to maintain core temperature.  Combined with reduced seagrass availability, …

Evaluation Of Electroencephalography Processing Methods For Estimating Metabolic Energy Expenditure During Walking, Stephanie L. Pinelo

Graduate Studies Theses and Dissertations 2026

In this study, three EEG datasets, created via different levels of pre-processing, were used to train VO2 prediction models whose performance was tested and compared. Understanding the link between EEG and VO2 during walking is important when working in rehabilitation or studying metabolic energy optimization. Common methods of measuring these two bio-signals tend to be bulky, uncomfortable, and inefficient, so finding a way to predict VO2 from EEG via 1D CNN model training is a worthy pursuit.  It was hypothesized that, due to a CNN needing more data to find patterns for prediction, a minimally processed EEG dataset would have …

Examining Attrition In Rtms For Smoking Cessation: The Roles Of Perceived Research Burden And Delay Discounting, Miranda Proctor

Graduate Studies Theses and Dissertations 2026

This secondary analysis examined predictors of attrition in a randomized clinical trial conducted by Roswell Park Comprehensive Cancer Center evaluating repetitive transcranial magnetic stimulation (rTMS) for cigarette smoking cessation. Smoking cessation reduces cancer risk and mortality and improves mental health outcomes. Although rTMS shows promise for supporting sustained abstinence by targeting neurobiological mechanisms underlying nicotine dependence, participant attrition threatens statistical validity, reduces power, and limits generalizability. Identifying predictors of attrition is therefore critical for optimizing trial design and retention.

Research examining predictors of attrition in smoking cessation trials remains limited. Prior work in other clinical populations suggests that higher perceived …

A Sensory Ecology Of Fear: Moonlight-Mediated Predation Risk And Foraging Behavior In Neotropical Electric Fish, Chiu Lok Poon

Graduate Studies Theses and Dissertations 2026

Animals must forage to acquire energy for survival and reproduction, yet foraging exposes them to predators. This creates a trade-off between energy intake and safety, wherein the perception of predation risk alone can alter activity patterns. Within this trade-off, risk, energetic needs, and sensory adaptations vary, shifting the balance and favoring different foraging strategies. Using Neotropical electric fish as a study system, I investigated how foraging under predation risk is shaped across biological scales, including environmental dynamics, interspecific sensory differences, activity-timing mechanisms, and intraspecific variations. These nocturnal fish emit continuous electric signals to sense their environment, allowing non-invasive monitoring of …

Old Maps Of The New World & New Theories On The European Encounter With La Florida: An Historical Archaeological And Four Field Anthropological Approach To Peter Apian's Cosmographia (1575), Emerson S F Richards

Graduate Studies Theses and Dissertations 2026

This thesis examines the 1575 Spanish edition of the Cosmographia, a geographic textbook initially authored by Peter Apian and expanded by Gemma Frisius, as a source for anthropological inquiry into early European encounters with the Americas. Little attention has been given to the text’s potential as a source for anthropological analysis, particularly regarding its representations of the Americas and the cultural information embedded in the geographic data. This study addresses that gap by applying a Four-Field anthropological framework—cultural, biological, linguistic, and archaeological—to this edition, which incorporates excerpts from Ieronimo Girava’s qualitative and quantitative description of the Americas, including a …

Monitoring Shifts In Estuarine Microbial Communities: A Dna-Metabarcoding Approach, Ashley M. Reaume

Graduate Studies Theses and Dissertations 2026

Estuarine microbial communities, including plankton, algae, and bacteria, play important roles in nutrient cycling and food web structure. They are sensitive to changes in abiotic conditions, and shifts in community composition can provide insight into estuarine ecosystem functioning in the face of various physiochemical and anthropogenic stressors. Therefore, monitoring these communities is essential for understanding and maintaining estuarine health. DNA metabarcoding is an emerging technique for enhancing biological monitoring, allowing for the detection of multiple species within a single sample. This dissertation first focuses on how methodological decisions impact DNA metabarcoding results and then implements these optimized methods to perform …

Exercise-Induced Muscle Swelling And Impedance Changes Of The Elbow Flexor, Sofea Smith

Graduate Studies Theses and Dissertations 2026

Electrical impedance myography (EIM) is a non-invasive method that assesses body fluid distribution using impedance (Z), resistance (R), reactance (Xc), and phase angle (PhA). These values have previously been used to interpret cellular health and fluid shifts. Acute muscle edema known as a “pump,” has been reported during and after resistance training exercise and the extent to which bioelectrical properties of the muscle tissue are affected during this process remains relatively unexplored. Therefore, the purpose of this study was to assess changes in EIM during exercise-induced muscle swelling via resistance training. Thirty-one resistance-trained adults (male=21, female=10; age=23.4±6.5 years, BMI=26.17±3.04 kg/m2) …

“I Call For The Resurgence And Reclamation Of Our Indigenous Ways”: Institutional Landscapes, Resistance, And The Experiences Of Mmir Advocates, Sara Tehrani

Graduate Studies Theses and Dissertations 2026

Indigenous Peoples across Turtle Island experience disproportionately high rates of violence and homicide compared to other racial groups. Rooted in coloniality and sustained by Western institutions, this epidemic is recognized as the Missing and Murdered Indigenous Relatives (MMIR) crisis. In response, Indigenous women have mobilized the MMIR Movement to raise awareness and advocate for institutional change. Although scholarship on MMIR has expanded, limited research has explored the experiences of MMIR advocates. This study interrogates the institutional landscapes that shape MMIR advocacy and explores the resistance strategies advocates employ to address the crisis. Using reflexive thematic analysis, this study examines semi-structured …

Volumetric Fluorescence Microscopy For High-Throughput And High-Sensitivity Imaging: From Single Molecules To Tissues, Le-Mei Wang

Graduate Studies Theses and Dissertations 2026

Fluorescence microscopy is an indispensable tool in the biological sciences, enabling researchers to investigate intricate subcellular structures, particularly for volumetric studies. However, conventional optical microscopy for volumetric imaging remains fundamentally constrained by imaging speed and throughput. To bypass traditional serial z-scanning, we introduce an axially scan-free method using a phase layer cake to modulate the system's point spread function. This approach projects volumetric information onto a 2D plane in a single shot, offering high flexibility in tuning axial depth alongside simultaneous multicolor imaging with high spatial resolution and sensitivity. This dissertation divides these technical advancements into cellular and tissue imaging …

One Family Under Kim:, Jared Johnson

BYU Asian Studies Student Journal

The Democratic People’s Republic of Korea (D.P.R.K. or the state), as one of the most isolated and controlled states in Asia, has since its founding attempted to shape the culture and ideology surrounding the family construct to support the rule of the socialist regime and its leaders, the Eternal President, Kim Il Sung, and his successors. In Korea, like the rest of East Asia, the traditional family unit has been a central societal structure for centuries. Largely based upon Confucianism, the nuclear family—referring generally to the biological family unit of parents and children—has determined not only the lifestyle and livelihood …

The Idea Of Air, Jonathan Skinner-Thompson

Publications

How we view air, especially clean air, has meaningful normative and practical implications. Today, it is commonly recognized as an exhaustible natural resource. But air was not always thought of as something to be conserved, developed, and used. This Article is the first to explore and interrogate that view.

The shift to seeing air as a resource started in the first part of the twentieth century. Previously, air was characterized by its limitless supply of oxygen: a pure public good. Over time, the quality of that good changed, and a precious resource emerged. That resource—especially its chemical and physical characteristics—inspired …

Finite Ventures, Andrew A. Schwartz

Publications

The law endows corporations and other business organizations with the awesome power of perpetual life—unless the charter expressly provides for a certain duration, such as ten years. But does anyone ever actually choose limited life? Why would they?

This article reveals that limited-life business entities—finite ventures—play a significant and underappreciated role in modern commerce. Private equity and venture capital funds, SPACs, and insurance syndicates are all organized with a limited lifespan.

Their motivation? This article claims that limited life is a valuable, but often overlooked, tool for ameliorating agency costs: the managers of a finite venture know they must produce …

Gender Therapy False Equivalency, Scott Skinner-Thompson

Publications

One critical dispute surrounding the rights of LGBTQ people and societal recognition of their existence is the legal debate regarding very different types of gender therapy. On the one hand, several states have banned the provision of gender-affirming medical care to transgender youth, positing that it is a dangerous form of mutilation. A separate set of states has banned the practice of so-called gay or gender conversion therapy that seeks to transform youth away from their queer identities, concluding that it is a form of abuse. Both sets of laws have been challenged in courts with the Supreme Court recently …

The Internet And The Lost Law Of Transit, Vivek Krishnamurthy

Publications

For centuries, the law of transit has specified when states must permit foreign persons and goods to traverse their territory on journeys beginning and ending beyond their borders. Transit is a right — not a privilege — that tempers territorial sovereignty. Though largely forgotten today, the right to transit springs from states’ responsibilities to the international community when their territory hosts infrastructure of global utility.

Yet the internet stands as a striking exception to this tradition. Despite its importance, no doctrine of transit constrains states’ power to block or disrupt internet traffic that merely passes through their territory. This is …

Against A Medical Exception To Equal Protection, Govind Persad

Publications

Government regulations of medicine sometimes treat patients differently based on their race or sex. Does heightened scrutiny apply to such regulations—as is usual when law treats someone differently based on a protected characteristic? Or is there a medical exception to equal protection?

Recently, in United States v. Skrmetti, the Supreme Court upheld a law that restricted access to medical treatments for transgender minors. Though its holding did not rely on medical exceptionalism, its discussion reinvigorated interest in a "medical exception" to equal protection: that medical decisions are exempt from the searching review applied when governmental decisions consider protected characteristics.

Secondary Teachers' Experiences In International Professional Development For Convergence Research In Stem And Tradition, Rachel Sparks White, Kristie S. Gutierrez, James K. Ferri

Teaching & Learning Faculty Publications

Convergence education promotes learning experiences that integrate science, technology, engineering, and mathematics (STEM) to address complex real-world problems. However, secondary teachers often report limited access to professional development (PD) and curricular resources that support transdisciplinary instruction. This exploratory case study examines how four secondary teachers (three chemistry; one engineering) made sense of a transdisciplinary PD model, Convergence Research in STEM and Tradition (CReST), that leverages cultural heritage artifacts (Renaissance frescoes) as boundary objects to connect chemistry, engineering, world history, and technology. Teachers participated in a four-day immersive PD experience in Firenze (Florence) and Pisa, Italy, that included site-based learning, interaction …

'I Want To Learn Biology And Preserve My Culture' Testing The Efficacy Of A Culturally Relevant And Context Specific Approach, Umar Adam, Musa Adekunle Ayanwale, Hafsat Mustapha, Sakibu Olajide Saibu, Tunde Owolabi, Adekunle Ibrahim Oladejo

Teaching & Learning Faculty Publications

Background

The dominance of Western-inspired teaching methods and instructional materials has contributed to cultural erosion in African schools. In response, increasing attention has been directed toward culturally responsive approaches to decolonising science education. One such approach is the Culturo-Techno-Contextual Approach (CTCA), which enables African students to conceptualize science as culturally embedded knowledge, integrated into their everyday experiences and practically relevant to their lived realities.

Purpose

This study examined the potency of the CTCA in enhancing students' achievement in the biology topic of variation, which is widely regarded as conceptually challenging.

Sample

The study involved 105 Senior Secondary II students from …

Pre-Service Elementary Teachers' Science Content Knowledge And Confidence: Teaching Science Methods With Metacognitive Awareness Activities, Demetrice Smith-Mutegi, Erika Wise

Teaching & Learning Faculty Publications

Few elementary teachers are confident in teaching science or in their science knowledge. This study sought to address this concern by investigating the impact of a science methods course on confidence and science knowledge for pre-service elementary teachers (PSETs). In this study, 23 participants enrolled in a teacher education program at a Midwest US university participated in a quasi-experimental pretest-posttest design. The participants engaged in course content, including metacognitive awareness activities, for a full semester and qualitatively described their confidence within the pre-post assessment survey. Results were analyzed using an independent samples t-test, mean content assessment scores, and paired samples …

Pre-Service Teachers' Perceptions Of Literacy In Stem Classroom Instruction By Implementation Of Project-Based Lessons, Sarah Ferguson, Maryam Enderson, Jamie Colwell

Teaching & Learning Faculty Publications

This study examines how project-based learning (PBL) supports pre-service STEM teachers (PSTs) in understanding and applying disciplinary literacy in classroom instruction. Conducted in a semester-long PBL course at a mid-sized public university, the research explores PSTs’ shifting perceptions of literacy in STEM and the challenges and successes they experience. Using qualitative methods grounded in student voice and case study frameworks, data were collected through focus groups, reflections, and lesson plan analyses. Findings show PSTs initially held narrow views of literacy but developed more nuanced understandings through PBL. Key successes included increased confidence and use of inquiry-based strategies; challenges involved time …

On Dark Skinned Jesus Of Nazareth: Why Color Matters, Nicholas Berkel

MA Theses

This thesis examines the historical, religious, and cultural consequences of portraying Jesus as white within Christian art. Although Western art has overwhelmingly depicted Christ with white skin, archaeological, and contextual evidence supports a dark-skinned Jesus rooted in the ethnogeography of first century Palestine. The persistence of a White Jesus has shaped religious imagination and perception for centuries, reinforcing racial hierarchy and legitimizing systems of white supremacy. Through an interdisciplinary analysis combining biblical studies, Christian iconography, ethnography of ancient Semitic, Greco-Roman, and Egyptian peoples, medieval symbolism, modern mass-produced imagery, and Black thought, this study demonstrates how Jesus’ original complexion was gradually …
