Challenging Myths In Speech-Language Pathology: A Scientific Review Of Augmentative And Alternative Communication (Aac) Use, Bilingualism, And Late Talking, Mariah Morris

Undergraduate Honors Capstone Projects

Persistent myths within the field of speech-language pathology continue to influence clinical decision-making and contribute to biases experienced by both providers and clients. This scientific review examines common misconceptions surrounding late talking, bilingualism, and augmentative and alternative communication (AAC) by evaluating current evidence-based research. Specifically, this review addresses three central questions: Do children outgrow late talking? Does bilingualism cause language delay in children? Does AAC hinder speech development? 

An analysis of multiple peer-reviewed studies revealed little statistical support for the belief that bilingualism or AAC use causes language delays. Instead, research indicates that factors such as limited access to language-rich …

Restorative Justice In Cache Valley: Building Community Resilience Through Restorative Practices, Rivkah Haubner

Undergraduate Honors Capstone Projects

Restorative justice as a field of study is primarily applied to criminal justice proceedings or similar topics. As such, its use as a tool in political organizing is an underdeveloped field. Due to its Indigenous history, restorative justice has intrinsically ant-colonial, anti-imperial, and anti-racist roots and is therefore already situated within the ethos of many progressive movements. Historically, radical movements within the United States and across the world experienced both internal and external pressures that undermined their goals. Restorative justice offers a framework through which to understand political action as a whole and specific tools to address internal conflict within …

Automating Building Feature Recognition In Digital Twin Models Using Computer Vision, Jaron Harbison

Undergraduate Honors Capstone Projects

Standard 3D scans treat all surfaces as generic geometry, but Wi-Fi signals don't. A signal drops by a different magnitude through a wooden door than a concrete wall. Without labeling these materials, Internet Service Providers (ISPs) cannot accurately predict "dead zones". This project addresses that gap by creating a machine learning model that identifies structural and architectural features. This includes features such as walls, doors, windows, and columns directly from RGB-D (Red, Green, Blue, Depth) point cloud data. 

I constructed the model on a custom U-Net architecture featuring a symmetric encoder-decoder structure with skip connections, trained on the StructScan3D dataset …

Paucilactobacillus Wasatchensis Gas Production In Cheddar Cheese Through Symbiotic Amino Acid Metabolism With Lactococcus Lactis Starter Cultures, Niharika Mishra

All Graduate Theses and Dissertations, Fall 2023 to Present

Cheese is popular for its rich sensory notes and desirable physical attributes; however, the late blowing gas defect in cheddar cheese disrupts its appearance and can undermine its commercial value, for example if the late gas defect is severe, the block can crumble upon cutting, increasing cutting losses from 10% (non-defective) up to 50% (Donnely et al., 2014).

Paucilactobacillus wasatchensis cannot survive pasteurization (McMahon, D. J., et al., 2020); therefore, it enters the cheese as a contaminant during the cheesemaking process. Cheesemaking occurs in three stages: (1) curdling of milk by acidification through starter cultures, (2) separation of curd from …

Effects Of Cannabinoid Agonist Win 55-212-2 On Latent Inhibition, Ashley Peterson

All Graduate Theses and Dissertations, Fall 2023 to Present

The endocannabinoid system (ECS) is a modulatory system that helps regulate brain functions, including learning and memory, influencing processes such as latent inhibition (LI). LI refers to the slower association formed when a familiar event is paired with a new outcome, compared to the association of an unfamiliar event. LI is a process that is often disrupted in individuals with schizophrenia and is known as a cognitive symptom. This study aimed to determine whether the drug WIN-55-212-2 (WIN), which interacts with the ECS, influences the process of LI using a fear-conditioned response procedure. The results found no significant interaction among …

Engineering programs often emphasize subject-matter expertise over pedagogical training, which can leave students struggling with course demands and contribute to retention challenges. This study applied Cognitive Load Theory (CLT) to examine how undergraduate engineering students experience the cognitive demands of their coursework compared to non-engineering classes. Using a sequential explanatory mixed methods design, cognitive load surveys were followed by interviews to address two research questions: (1) What are the differences in intrinsic and extraneous cognitive load levels between engineering courses and non-engineering courses taken concurrently by undergraduate engineering students? (2) How do engineering students perceive the unique challenges or benefits …

A Low Power Fpga Compute Array For Machine Learning And Artificial Intelligence Applications, Todd Wilson

All Graduate Theses and Dissertations, Fall 2023 to Present

Modern small satellites often lack the ability to analyze their data in real time, relying instead on downlinking raw measurements to Earth before any scientific interpretation can occur. This delay restricts missions that require rapid awareness of environmental or space-weather events. This thesis presents the Low-power Array for Cubesat Edge Computing Architecture, Algorithms, and Applications (LACE-C3A), a hardware platform designed to enable in-orbit data processing within the power and volume limits of CubeSat-class spacecraft. 

LACE-C3A uses a modular cluster of flash-based FPGAs, which offer low power consumption, radiation resilience, and in-flight reconfigurability. The system consists of a Controller board responsible …

Ionospheric Plasma Electron Density Measurement And Theory Using Impedance Probe Techniques, Justin Wellington

All Graduate Theses and Dissertations, Fall 2023 to Present

The ionosphere plays a critical role in how radio frequency (RF) signals, like those used in Global Position System (GPS) satellite communications, travel through space. Disturbances in the ionosphere, such as equatorial plasma bubbles (EPB), scatter these signals and cause communication dropouts or navigational errors. To study these conditions, spacecraft use instruments that measure the surrounding plasma directly. One of these instruments is an impedance probe, which applies a small electrical signal to a sensor and determines electron density from the measured impedance.

This thesis improves the modeling and interpretation of impedance probe measurements. A numerical method is developed that …

Data was collected through interviews with two active, competing adult female members of the United States Hunter Jumper Association. Key findings from analyzing these equestrians’ relationships with different elements in their learning environment include the finding that equestrians shift between viewing horses as material objects or social partners, depending on the context. It was also seen that an equestrian’s skill is not dependent solely on the rider, but is influenced …

Aerodynamic Parameter Estimation For A Scaled F-16: A Simulation-Based Sensitivity Analysis, Kathle C. Tischner

All Graduate Theses and Dissertations, Fall 2023 to Present

The physical motion of an aircraft is determined by the resulting forces and moments acting on the aircraft. These forces and moments can be defined as a mathematical equation where the control deflections, rotation rates, and orientation of the aircraft are multiplied by individual constants and summed together to define the entire force or moment. This method results in a highly accurate model that defines the motion of the aircraft at low angles of attack and sideslip. Initial calculations of the aerodynamic model are created based on analytical estimations based on the physical properties of the aircraft. Additional refinement of …

Sequential Products Of Anaerobic Denitrification In Calcareous And Noncalcareous Soils By Use Of The Gas Chromatograph, Grant S. Cooper

All Graduate Theses and Dissertations, Fall 2023 to Present

LGBTQ+ teens face challenges like discrimination and exclusion from school-based sex education. Support from parents is crucial for helping LGBTQ+ teens feel safe and confident. Most research has only looked at how parents react when their child comes out, and less about how parents support their child in everyday life. This two-study dissertation explored how parents help support and protect their LGBTQ+ teens’ well-being over time.

The first study looked for patterns of protective parenting across interviews with LGBTQ+ teens and their parents from diverse racial and ethnic backgrounds. Teens and parents shared their experiences of open communication, building community, …

Online Act Guide For Sub-Clinical And Clinical Insomnia Among College Students, Guadalupe "Gabe" San Miguel

All Graduate Theses and Dissertations, Fall 2023 to Present

College students are shown to have more sleep difficulties, specifically insomnia. These sleep difficulties compared to the general public due to the college environment (for example increase screen time, sedentary time, or alcohol use). Students with reported sleep difficulties have ties to lower GPA and lower odds of graduation. That is why this dissertation conducted a comparison between an online version of Acceptance and Commitment Therapy (intervention) to a placebo condition among college students with insomnia to help determine if the intervention had better outcomes over time. Each condition (intervention = 39; placebo = 40) completed questionnaires at the start …

The primary research objective is to evaluate the efficacy of this method in accommodating the physical thrust constraints of a spacecraft. This approach is tested in simulation with an unstable halo orbit around the Moon in the circular restricted three-body problem (CR3BP) model. The simulation incorporates realistic disruptions from …

Adversarial Heterogeneous Agent Learning For Robotic Systems: A Framework For Coordinated Competitive Behaviors, Christopher T. Allred

All Graduate Theses and Dissertations, Fall 2023 to Present

Autonomous robot teams must move reliably, explain their actions, and work together—even in changing or adversarial settings. We present a structured, three-stage pathway that builds coordinated team behavior from strong single-robot skills. First, we develop robust legged-robot locomotion and interpretability using only internal actuator signals. From these proprioceptive cues, robots learn to classify terrain and predict short-term power use, enabling energy-aware movement without external sensors. We further analyze learned behaviors with motif discovery to reveal recurring sensor–action patterns, which clarify how agility emerges and guide reward design. Second, we compose these skills into heterogeneous teamwork using centralized training with decentralized …

Beyond Morphology: Testing Molecular Assessment Of Macroinvertebrate Communities In Alpine Streams Of The Teton Range, Usa, Joshua Vollmer

All Graduate Theses and Dissertations, Fall 2023 to Present

Alpine streams and the macroinvertebrate communities that reside within them are threatened by the rapidly changing climate. Long-term monitoring of these communities is required to understand how they are changing and to predict their future trajectories. Historically, stream monitoring and assessment has been performed by collecting and identifying individuals using their morphological traits. However, in alpine aquatic ecosystems, distinct macroinvertebrate species often lack the morphological differences that allow them to be distinguished. DNA metabarcoding, an alternative method for identification which uses genetics instead of morphological differences, is not impacted by this issue, and therefore, may be better suited for alpine …
