Context-Sensitive Control-Flow Analysis For Non-Standard Language Semantics, Tim Whiting

Theses and Dissertations

Control-Flow Analysis (CFA) is a static technique for understanding the execution of higher-order programs without running the code. CFA aids in identifying bugs, assisting program comprehension, and exposing optimization opportunities. Constructing a CFA typically begins with an idealized evaluator--such as an abstract machine or interpreter--and proceeds by approximating components of evaluation to ensure that: (a) the analysis is sound (representing all possible behaviors), and (b) the analysis is guaranteed to terminate (finitely representable). These constraints necessitate a loss of precision, providing an approximation of the values that flow to program locations rather than exact execution traces. This imprecision causes the …

Automated Detection Of Bacterial Flagellar Motors, Eben J. Lonsdale

Undergraduate Honors Theses

With advances in cryogenic electron tomography, the ability to study bacterial structures in their cellular context has improved. However, 3D images of bacteria, called tomograms, have a low signal-to-noise ratio. This makes annotating structures of interest difficult, as traditional computer vision models struggle with tomograms and manual annotation is time consuming. We build on the results of the BYU Kaggle competition to create an ensemble model capable of automatically annotating flagellar models with nearly around 85% accuracy.

A Peer Evaluation Of Safety At Signalized Intersections, Auzton Mitchell Stutts

Theses and Dissertations

The Utah Department of Transportation (UDOT) has made significant efforts to reduce crashes at signalized intersections and is constantly seeking to improve safety across the state. The purpose of this research is to quantify and evaluate the safety rates and frequencies at signalized intersections in Utah compared to other states. Once the crashes have been quantified, the secondary purpose is to determine why there may or may not be differences. A survey was developed to understand how states analyze, prioritize, and implement safety at signalized intersections, including different policies, procedures, and countermeasures. Crash data from eight states were analyzed and …

Development Of A Low-Cost Roadside Monitoring System For Identifying High-Emitting Heavy-Duty Trucks, Spencer Larson

Theses and Dissertations

This project investigated the feasibility of using low-cost sensors to identify high-emitting heavy-duty diesel trucks through roadside emissions monitoring. A sampling system was designed and tested in both laboratory and field environments to evaluate sensor performance and measurement reliability. In the laboratory, controlled engine testing enabled direct comparison between low-cost sensors and research-grade instruments to establish baseline accuracy, response time, and sources of uncertainty. These tests demonstrated that while low-cost sensors exhibit greater bias and slower response, several are capable of detecting transient emission events. Field deployments revealed that real-world conditions, such as plume dilution, spatial variability, and short exposure …

Wounded Domestic Ecologies: Ecofeminist Readings Of Gendered Trauma In Purple Hibiscus, Erere Victory Iwhi

Theses and Dissertations

This thesis examines Chimamanda Ngozi Adichie's Purple Hibiscus through an ecofeminist and postcolonial ecocritical lens, developing the concept of "wounded domestic ecology" to analyze how gendered violence operates within domestic space. Drawing on trauma studies, particularly J. R. Kurtz and Rob Nixon's concept of slow violence, it argues that harm in the novel is accumulative, produced through repetition, surveillance, ritual, and spatial regulation. Eugene's household functions as an environment that disciplines bodies, governs language, and embeds fear into everyday life. In contrast, Aunt Ifeoma's home in Nsukka offers a counter-ecology structured by sound, shared labor, and dialogic authority, interrupting the …

Effects Of Divided Attention On Linguistic Tasks And Speech In Healthy Young Adults, Allison Coca

Theses and Dissertations

The purpose of this study was to determine the effects of divided attention on concurrent speech and linguistic tasks by investigating performance on three linguistic computer tasks (phonological, syntactic, and semantic) and speech kinematics. Thirty-seven healthy young adults (19 male, 18 female) ages 19-30 were recorded performing a sentence repetition task using electromagnetic articulography. Each participant completed the sentence repetition once in isolation and once concurrently with each of the three linguistic computer tasks. Participants also completed computer tasks in isolation. Significant dual-task effects were observed on total number of correct responses in the phonological and syntactic linguistic tasks. No …

Multilingual Assessment Practices In School-Based Speech Language Pathologists, Carolyn Alana Ferguson

Theses and Dissertations

Multilingual assessment is an area of growing relevance and importance in the field of speech language pathology. The purpose of this study was to evaluate the current assessment practices among school-based SLPs in relation to their language background status (e.g. monolingual, bilingual, multilingual) and their perceptions on issues related to multilingualism. A survey instrument was created, which asked SLPs to respond to questions on various topics, including demographics, caseload information, assessment practices, statements on multilingual perceptions, and clinical scenarios. There were 267 participants included in the study from across the country with varying ages and years of experience in the …

Harnessing Story To Overcome The Double Empathy Problem Between Autistic And Neurotypical People: Brain-Behavior Relationships, Kate Gifford

Theses and Dissertations

There is a dearth of information on the physical aspects of the Double Empathy Problem which is the bidirectional challenge of shared empathy and understanding between autistic and neurotypical individuals. Storytelling has been shown as means to facilitate empathy between storytellers and listeners in both neurotypical and autistic populations through behavioral research. Functional near-infrared spectroscopy (fNIRS) is a neuroimaging technique used to evaluate the hemodynamic response in the cortex and can be used to compare hemodynamic responses across multiple individuals (i.e., hyperscanning). The purpose of this study was to examine activation in empathy-related brain regions and assess brain synchrony between …

Spatiospectral Lobes And Radiation Modeling Of Partially Coherent Supersonic Jet Noise, Tyce Wayne Olaveson

Theses and Dissertations

Noise fields generated by high-performance military jets are known to contain acoustic structures that differ from their simulated and lab-scale counterparts. These differences may limit current noise control efforts, which are designed and tested at scale before being considered for full-scale aircraft. One such noise structure is the presence of spatiospectral lobes, which appear as multiple spectral peaks at single microphone locations and multiple radiation lobes in field reconstructions. This dissertation uses data collected from the T-7A jet noise measurement to characterize the spatial behavior of the spatiospectral lobes as well as their first time-domain description. A multiple wavepacket decomposition …

Narrative Blindness: Gretta And The Limits Of Seeing In Joyce’S “The Dead”, Madison Reber

Criterion: A Journal of Literary Criticism

This essay examines narrative vision and its correlation with gender representation in James Joyce's “The Dead,” focusing mainly on how the narration renders Gretta both visible and unseen. The story is framed by the language of sight in which words such as eyes, watching, and looking repeatedly reveal how meaning is formed. Yet the narrative consistently restricts readers from seeing Gretta's interiority, reducing her to a mere reflection of Gabriel's consciousness, which leads Gretta to become an example of what Simone de Beauvoir theorizes as “the Other”. Scholars commenting on “The Dead” often note that Gretta's objectification comes from Gabriel's …

Take Me To The Museum: Exploring The Use Of Art Kits For Families In The Art Museum, Amanda Marriott Elton

Theses and Dissertations

This study examines the use of participatory art kits as a strategy for transforming family engagement within the art museum setting. Drawing on theories of experiential learning from John Dewey and participatory art practices rooted in the Fluxus art movement, my research positions art kits as tools that invite active, social, and embodied learning. Using a design-based research methodology, this study investigates how families interact with art kits within gallery spaces and how these tools influence and encourage conversation, artistic behaviors and relational dynamics. Data were collected through observation, family feedback and iterative kit redesign. Findings suggest that art kits …

Here-, There-, And Every Where-: Exploring The Role Of Pronominal Adverbs In Legal Language, David Chandler

Undergraduate Honors Theses

Legal language is distinctive and sometimes difficult to understand. One type of word that appears to be part of so-called ‘legalese’ is the pronominal adverb (PA). The purpose of this thesis is to examine the prevalence of PAs in legal registers compared to more general registers of contemporary American English to determine the extent to which these words are distinctly legal. The study will also explore why different types of PAs may be (in)frequent in specific legal registers to better understand their use. The frequency of PAs was extracted from corpora that are designed to represent six registers of English …

Effects Of A Complexity-Based Expressive Language Treatment On Comprehension In Children With Down Syndrome: A Preliminary Investigation, Aliese M. Pedro

Theses and Dissertations

This study examined whether a complexity-based expressive morphosyntactic intervention targeting auxiliary BE questions improves morphosyntactic, vocabulary, and narrative comprehension in adolescents with Down syndrome (DS). Two participants (ages 15;11 and 14;2) received intervention delivered over 15 and 12 sessions, respectively, using a structured narrative-based protocol. Comprehension was assessed pre- and post-intervention using the Clinical Evaluation of Language Fundamentals-Fifth Edition (CELF-5) Following Directions subtest, the Peabody Picture Vocabulary Test-Fifth Edition (PPVT-5), the Test of Narrative Language-Second Edition (TNL-2), and the Test of Early Grammatical Impairment (TEGI) Grammaticality Judgment (GJ) task. Results indicate no reliable or clinically significant improvements in comprehension across …

An Exploration Of The Lived Experience Of Married Couples Impacted By Aphasia, Summer Ewell

Theses and Dissertations

People with aphasia and those closest to them experience changes in their lives and relationships due to aphasia. These changes may be particularly impactful for married couples. The aim of this study was to increase understanding of the dynamic and complex experiences of couples impacted by aphasia and to add personal perspectives to the creation of practical treatments and resources. Twenty-eight participants (14 married couples) participated in both individual and couples' semi-structured interviews, resulting in 42 total interviews for analysis. Participants answered open-ended questions about aphasia's influence on the couple's communication and relationship. Interviews were then transcribed orthographically and coded …

The Relationship Between Musical Ability And Perceptual Skills For Speech Motor Learning In Young Adults, Emily Catmull

Theses and Dissertations

Speech motor learning is the multimodal process of acquiring speech sounds. Speech motor learning is trained through speech-language pathologist intervention in individuals across the lifespan. Previous research has explored which factors can influence speech motor learning, such as musical experience or training, which is the subject of this study. Sixty young adult participants (four male, 56 female) were recruited as part of a larger study that examined four possibly influential factors: bilingualism, phonetic knowledge, perceptual skills, and musical experience. Since the adult population has already acquired all the speech sounds in English, learning was measured using nonnative consonant clusters. Participants …

Panda-Plus-Bench: A Clinical Benchmark For Evaluating The Robustness Of Ai Foundation Models In Prostate Cancer Diagnosis, Joshua L. Ebbert, Dennis Della Corte

Faculty Publications

Artificial intelligence foundation models are increasingly deployed for prostate cancer Gleason grading, where GP3/GP4 distinction directly impacts treatment decisions (active surveillance vs. intervention). However, these models may achieve high validation accuracy by learning specimen-specific artifacts rather than generalizable biological features, limiting real-world clinical utility. We introduce PANDA-PLUS-Bench, a curated benchmark dataset derived from expertly annotated prostate biopsies designed specifically to quantify this failure mode. The benchmark comprises nine carefully selected whole slide images from nine unique patients containing diverse Gleason patterns, with non-overlapping tissue patches extracted at both 512 × 512 and 224 × 224-pixel resolutions across eight augmentation conditions. …

An Informationally Novel Sense Of Triviality For Harman’S Clutter Principle, Joseph D. Rasmussen

Undergraduate Honors Theses

Gilbert Harman (1986) argues that we ought not believe some logical consequences of our beliefs. To do this, he uses the Clutter Principle—that we should not clutter our minds with trivialities—and claims that some logical consequences are in some sense trivial. I show that interpreting Harman’s argument using an interest-driven sense of triviality (e.g. what Friedman calls junk) conflicts with a plausible epistemic norm. In light of this, epistemologists have turned the Clutter Principle into a norm on inquiry. This, however, loses the strength of the Clutter Principle in Harman’s argument. In this paper, I provide an alternate sense of …

The Correlation Between Perceptual Abilities And The Acquisition Of Non-Native Consonant Clusters, Hope Emma Nielson

Theses and Dissertations

A common approach in the study of speech motor learning is to have speakers learn to produce clusters of consonants that do not occur in their native language. This study investigated the relationship between auditory or speech perceptual abilities and the initial acquisition of non-native stop-stop consonant clusters. Sixty young adult participants (56 female, four male) were administered a gap detection test and a speech-in-noise test to assess their innate perceptual skills. The participants then performed a nonsense-word repetition task featuring non-native consonant clusters in the initial position. The participants' spoken productions of the nonwords were recorded and analyzed acoustically …

The Reliability Of Yolo Object Detection On The Amd Versal In A Proton Radiation Environment, Jacob D. Brown

Theses and Dissertations

Object detection is an important operation for satellites to be able to perform, and in outer-space missions it is crucial that machine learning models perform inference on satellite images accurately and reliably. Where size, weight, power, and other constraints exist, meeting this goal for accurate and reliable object detection is challenging. Additionally, soft errors caused by radiation further disrupt and degrade the operation of object detection in satellites. This thesis studies the performance of a deep learning model on an embedded device, the AMD Versal, in the presence of soft errors. The well-known and high-performing YOLO convolutional neural network was …

The Effects Of Phonetic Knowledge And Bilingualism On The Acquisition Of Non-Native Consonant Clusters, Kylie Wakley

Theses and Dissertations

Speech motor learning involves the production of new sounds or sound sequences. This study investigated how explicit phonetic knowledge and bilingualism affect how individuals acquire sound sequences that do not occur in English, or non-native consonant clusters. Sixty adults with typical speech, aged between 18 and 27 years, participated in the experiment. The researcher recruited participants into four groups based on their phonetic background (experienced or not) and language background (monolingual, bilingual). The participants produced stop-stop and fricative-nasal clusters in the initial position of nonsense words across six practice blocks. The duration of each cluster was measured, which in English …

The Impact Of Response Latency On Perceived Level Of Intelligence And Likability Of Autistic Speakers, Brinley Atkinson

Theses and Dissertations

The purpose of this study was to examine how turn-taking latency and speaker or listener gender affect the perceived intelligence and likability of the speaker across autistic speakers. In addition, the overarching goal of this research is to help speech-language pathologists (SLPs) better provide support and strategies to autistic individuals to improve their social and professional lives. Neurotypical English speakers (20 male and 20 female) were recruited to listen to a series of conversational speech samples collected from a group of eight autistic adults (four male and four female). In each sample, autistic individuals responded to a series of everyday …

Functional And Structural Lesion Network Mapping: Insights Into Acquired Brain Injury And Insomnia, Kathleen Erekson Rugh

Theses and Dissertations

Insomnia disorder is the most reported sleep disorder and can negatively affect daily functioning. Acquired brain injuries can lead to insomnia disorder. Limited research has explored a causal link between brain networks and insomnia symptoms in this population. This study replicated a lesion network mapping methodology of an insomnia study (Helquist et al., 2024) and extended it to examine structural networks linked to insomnia symptoms in individuals with acquired brain injuries. Traced lesions (N =44) were used as seed regions to compare against normative functional and structural network data. For functional analyses, we used resting state fMRI scans from a …

Real-Time Instruction Internalization For Large Language Models, Brenden Smith

Theses and Dissertations

For the end user, Large Language Models (LLMs) are programs that process natural language inputs into natural language outputs. In popular usage, this tends to take the form of conversation: a user asks a question, provides information, or gives instructions, and the LLM (hopefully) replies in a manner we would expect of an informed and compliant person. While convenient and intuitive for users, this natural conversational format encourages the misconception that LLMs are learning from conversations, when they do not. This work presents the benefits and practicality of a language model paradigm that meets this user expectation -- that is, …

Beyond Pedagogical Inertia: Understanding And Overcoming The Barriers To Effective Faculty Work In Higher Education, Yoshihiko Ariizumi

Learning, Teaching, & Researching Optimization

Academic faculty are among the most educated professionals in the world. Yet a striking body of empirical research demonstrates that they face profound, systematic barriers to performing their own work effectively—barriers that are cognitive, institutional, cultural, and structural in origin. This paper extends the analysis of “pedagogical inertia” beyond the classroom to the full scope of faculty professional life: research, writing, service, advising, and self-directed learning. Drawing on evidence from organizational psychology, cognitive neuroscience, higher education research, and behavioral science, we identify six classes of barriers that consistently impede effective faculty work, and we analyze—with reference to documented successful cases—the …

Empowering Audio Recording: Academic Supporting Views, Yoshihiko Ariizumi

Learning, Teaching, & Researching Optimization

This paper aims to demonstrate, drawing on findings from cognitive science, educational psychology, and creativity research, the proposition that incorporating voice recording into daily intellectual production activities can substantially enhance individual intellectual productivity.

One of the greatest challenges facing contemporary knowledge workers and learners is the asymmetry between the difficulty of securing uninterrupted time for thinking, on the one hand, and the latent abundance of fragmented “half-released” time in daily life—during commutes, household chores, exercise, waiting, and the like—on the other. This study proposes a methodology for resolving this asymmetry through recording technology.

As the conceptual framework of the paper, …

Intern Experience And Support In The Byu-Public School Partnership, Ryan S. Nixon, Rebecca K. Hunter, Paul H. Ricks

Faculty Publications

This study examines the experiences and perceived support of early childhood and elementary education interns in the BYU–Public School Partnership. In June 2025, 137 former interns (54% response rate) completed an anonymous survey with open-ended prompts, and responses were qualitatively analyzed. Most interns characterized the experience as positive or both good and hard (84%), though 16% reported largely negative experiences. Relationships with students were consistently identified as the most meaningful aspect, often providing motivation during difficult periods. Support was most frequently attributed to facilitators, with additional support from grade-level teams and Clinical Faculty Associates (CFAs). While generally helpful, support was …

Engagement Modeling And Inference For Risk-Aware Path Planning Under Adversarial Uncertainty, Grant Stagg

Theses and Dissertations

This dissertation develops methods for planning safe and efficient trajectories for autonomous vehicles operating in environments containing adversarial and environmental threats with uncertain parameters. The central objective is to quantify and control the risk of adverse events--such as interception or detection--when threat characteristics are imperfectly known. To address this challenge, probabilistic weapon engagement zone (PEZ) models are introduced to estimate the likelihood of violating adversarial engagement constraints under uncertainty in pursuer state and capabilities. Multiple computational strategies are developed for PEZ evaluation, including first-order sensitivity-based approximations, Monte Carlo estimation, and neural-network surrogate models. These approaches enable rapid engagement-probability assessment and …
