Instrumentality: How We Develop Relationships With Objects And People, Nathaniel Bee

Undergraduate Honors Capstone Projects

There are many different types of relationships a person will have throughout their life, each being given varying levels of authenticity, weight, and care. One’s attention is primarily placed upon the meaningful relationships in one’s life, but often deeper consideration of one’s “lesser” relationships is neglected. Networking and professional relationships are often impersonal. Family members will often lie to each other in favor of avoiding conflict. The emotional labor of service workers often goes underappreciated and undercompensated. Careers in the political sphere revolve heavily around maintaining a positive public image, and there are well-observed disparities between politicians’ stated values and …

The Effects Of An Equine Riding Simulator As An Objective Feedback Modality On Learning Outcomes For Rider Competency On Performance Skills In Equestrian Riding Fundamentals, Kelli Munns

All Graduate Theses and Dissertations, Fall 2023 to Present

This study examined the effects of different feedback modalities provided during simulated-based practice on performance and perceptions. In addition, the research also addressed the relationship between participants' feedback literacy, perceptions, and improvement scores. The purpose of this research was motivated by the emerging equine simulation technology that provides feedback on movement and coordination during complex motor skill acquisition. Selecting an effective feedback approach for simulation-based practice in motor skill learning is contingent on the complexity of the performance skill and the learner's experience. However, the learner's feedback literacy can result in contradictory performance and perceptions despite the feedback approach experienced. …

Integrated Behavioral-Health Supports: Combining Pbis And Sel At Tier 2, Thomas K. Franzmann

All Graduate Theses and Dissertations, Fall 2023 to Present

Childhood behavior problems present many challenges for youth, families, and schools. To assist in preventing and reducing such problems, schools have adopted various strategies to assist with such concerns. Two widely used strategies for addressing problem behavior in schools are Positive Behavioral Interventions and Supports (PBIS) and Social-Emotional Learning (SEL). While both have a plethora of evidence of their effectiveness independently, less is known as to whether than can compliment one another for even better outcomes. The current study examined the effectiveness of an integrated approach (PBIS + SEL) to classroom intervention for elementary school students exhibiting behavior problems. This …

The purpose of this study was to investigate the relationships between English and Chinese handwriting fluency measures in early-elementary Chinese Dual Language Immersion students. This was done by conducting five handwriting fluency tasks among Chinese Dual Language Immersion students and comparing the findings. First, the findings showed that there was a moderate correlation between the participants' English and Chinese handwriting fluencies and that English fluencies predicted Chinese fluencies. However, the students could write English numbers and letters much faster than Chinese characters. Second, as expected, Chinese DLI participants showed that handwriting fluency improved as grade level increased. Third, third-grade students …

Development, Implementation, And Optimization Of A Modern, Subsonic/Supersonic Panel Method, Cory D. Goates

All Graduate Theses and Dissertations, Fall 2023 to Present

In the early stages of aircraft design, engineers consider many different design concepts, examining the trade-offs between different component arrangements and sizes, thrust and power requirements, etc. Because so many different designs are considered, it is best in the early stages of design to use simulation tools that are fast; accuracy is secondary. A common simulation tool for early design and analysis is the panel method. Panel methods were first developed in the 1950s and 1960s with the advent of modern computers. Despite being reasonably accurate and very fast, their development was abandoned in the late 1980s in favor of …

Evaluating The Effects Of Ketamine On Cognitive Flexibility In Rats Using A Probabilistic Reversal Learning Task, Anthony N. Nist

All Graduate Theses and Dissertations, Fall 2023 to Present

Depression is one of the most debilitating and widespread mental health conditions in the world today. Drugs that are traditionally prescribed to combat depression are flawed in several ways, and because of this, new treatments are needed. One drug that seems capable of overcoming the limitations of traditional antidepressants is ketamine. In clinical research, a single dose of ketamine can significantly reduce symptoms of depression quickly, its effects may last for weeks to months, and its side effects appear to be limited and relatively harmless. However, clinical research is ongoing, and more research is needed to fully understand ketamine's beneficial …

Consensus Modeling As A Cultural Practice: A Case Study From A Seventh-Grade Science Classroom, Sara Louise Miconi Gailey

All Graduate Theses and Dissertations, Fall 2023 to Present

Recent reforms in science education aim to involve K-12 students in practices similar to those of professional scientists. These reforms promote student collaboration and science practices including developing models and engaging in scientific argumentation with evidence. Small group work in science classrooms has increased following the reforms. However, while small group collaboration has gained popularity, research suggests that it does not always lead to equitable participation. This qualitative case study uses discourse analysis to examine how two small groups of students in a seventh-grade science class develop consensus models of a phenomenon and how students are socialized to participate in …

Did Arroyo Formation Impact The Occupation Of Snake Rock Village, A Fremont Dryland Agricultural Community In Central Utah, Ca. Ad 1000–1200?, Alexandra Wolberg

All Graduate Theses and Dissertations, Fall 2023 to Present

Fremont farmers of the northern Colorado Plateau grew maize at the limits for cultivation in western North America between AD 300–1300. Like other Indigenous farmers throughout the American Southwest, Fremont farmers used bundled agricultural niches where alluvial floodplains were the largest available site for cultivation. But dryland floodplains are a risk to the persistence of farming communities because the development of steep-sided arroyos lowers floodplain surfaces and water tables, rendering them unusable for growing maize. This study tests the relationship between the occupational timing of Snake Rock Village between AD 970–1240 and the formation of a 4.5m deep arroyo on …

All Graduate Theses and Dissertations, Fall 2023 to Present

Many space organizations have a growing need to fly several small satellites close together in order to collect and correlate data from different satellite sensors. To do this requires teams of engineers monitoring the satellites orbits and planning maneuvers for the satellites every time the satellite leaves its desired trajectory or formation. This task of maintaining the satellites orbits quickly becomes an arduous and expensive feat for satellite operations centers. This research develops and analyzes algorithms that allow satellites to autonomously control their orbit and formation without human intervention. This goal is accomplished by developing and evaluating a decentralized, optimization-based …

Evaluating Implementer Preference For And Correspondence Between Structured Descriptive Analysis And Trial Based Functional Analysis, Kacy Rodamaker

All Graduate Theses and Dissertations, Fall 2023 to Present

Determining the function of maladaptive behavior aides in the creation of effective intervention measures to change that behavior. Three assessments that are used to determine behavioral function include the trial based functional analysis (TBFA), structured descriptive analysis (SDA), and antecedent-behavior-consequence (ABC) recording. In the present study, we compared the time it took to conduct each of these assessments as well as the similarity between the functions identified by each assessment. Additionally, we compared procedural acceptability and implementer preference between the SDA and TBFA by collecting survey results from a staff participant who implemented the two measures with the support of …

Using Telehealth To Teach Caregivers Mand Training Using A Speech Generating Device, Sara Jeppson

All Graduate Theses and Dissertations, Fall 2023 to Present

Children with ASD often have struggles with social communication and developing a functional vocal output. Alternative and augmentative communication (AAC) can be used in different modes such as speech generating devices (SGDs) to help these individuals develop a vocal output. Caregivers are optimal to aid their children in learning these communication skills. Past studies such as Suberman and Civindini-Motta showed that behavioral skills training (BST) can be effective to teach caregivers communication training using an SGD. The current study aimed to replicate the procedures of Suberman and Civindini-Motta but extended it by adapting the procedures described using telehealth.

Dominant Cognitive Strategy In Aphantasia, Sarah N. Pope

All Graduate Theses and Dissertations, Fall 2023 to Present

The purpose of this research was to explore the impact on thinking when an individual is not able to "see with a mind's eye." This is known as aphantasia and is the reduction or absence of visual imagery, which can have large impacts on problem solving and remembering one's own past. The current study examines these impacts by exploring the different ways in which thinking may occur, verbal-analytical, visual imagery, spatial imagery, and how a one's dominant thinking strategy affects performance on a paired work task, a mental rotation task, and an object memory task. Comparing those with typical imagery …

Metapopulation Genomics Of American Goshawks In The Intermountain West, Megan M. Sidran

All Graduate Theses and Dissertations, Fall 2023 to Present

Understanding a species dispersal ecology and population dynamics is essential to effectively manage and conserve a species. As advancing technology improves our knowledge of species movements, it is becoming clear that many species form metapopulations to some extent. A metapopulation is a network of interconnected subpopulations that exchange reproductive individuals with subpopulations occupying nearby patches. Metapopulations have been observed in a variety of species, ranging from plants to vertebrates, and can vary greatly in their dynamics (level of connectivity and gene flow) based on the species behavior and life history strategy.

Forming a metapopulation can add much resilience to the …

Effect Of Delay On Reinforcer Preference As Measured By A Paired Stimulus Preference Assessment, Emma Preston

All Graduate Theses and Dissertations, Fall 2023 to Present

Behavior interventions often utilize rewards to increase appropriate behavior. Current methods for identifying potential rewards only use immediately available items, however rewards in school or clinic settings are often delayed due to circumstance. Delay can decrease the value of a preferred stimuli. We propose and evaluate a method for considering delay to delivery of a preferred item when selecting a potential reward by asking children 8-11 to pick between a moderately preferred item immediately available or a highly preferred item that was delayed. 4 out of 5 participants increased selection for the moderately preferred item as delays to the highly …

Impact Of Moisture Content And Composition On Flow Properties Of Dairy Powders, Katelynn Palmer

All Graduate Theses and Dissertations, Fall 2023 to Present

Milk protein concentrate (MPC) and isolate (MPI), and milk permeate powder (MPP) are functional dairy powder products that are used in food applications worldwide. It is critical that environmental factors and physical powder characteristics during production and storage are controlled. When dairy powders are exposed to non-ideal conditions (high moisture, varying temperatures,) they can quickly become very sticky, and clumpy. When powders become sticky, their ability to easily flow is reduced. As a result, processing and storing the powders effectively and sustainably becomes very difficult.

In the first study, an analysis method was created to test the general flow behavior …

Characterization Of The Long-Distance Dispersal Kernel Of White-Tailed Deer And Evaluating Its Impact On Chronic Wasting Disease Spread In Wisconsin, Mennatallah Gouda

All Graduate Theses and Dissertations, Fall 2023 to Present

Chronic Wasting Disease (CWD) is a fatal, untreatable neurodegenerative disease that infects deer and related species. It is highly contagious and caused by abnormal malfunction and assembly of normal cellular proteins into aggregation-prone proteins. The Centers for Disease Control and prevention report that the prevalence of CWD in free-ranging deer in the US is still relatively low. However, in several states the infection rates exceed 1 deer in 10. Deer may uptake CWD from direct interaction with infected individuals or from the environment. Infected individuals shed CWD into the environment through feces, urine, saliva or carcasses, and long-distance dispersal of …

Inundated Vegetation Response To Ongoing Restoration And Its Impacts On Fish Community Structure, Emmanuel J. May

All Graduate Theses and Dissertations, Fall 2023 to Present

Shallow lake ecosystems and their associated wetland habitats globally are subject to non-native species introductions, nutrient loading, and water level fluctuations, each of which can decrease vegetated habitat availability, exposing vulnerable native aquatic species to predation. Managers are frequently tasked with mitigating native species declines by restoring vegetation considered crucial for their survival. However, restoring vegetation can be challenging in the presence of multiple stressors, requiring managers to assess the relative importance of the different stressors limiting vegetation recovery.

Utah Lake is a large shallow lake subject to multiple stressors and has shifted from a mesotrophic lake with abundant aquatic …

Gps-Denied Navigation Using Synthetic Aperture Radar, Tucker Hathaway

All Graduate Theses and Dissertations, Fall 2023 to Present

In most modern navigation systems, GPS is used to determine the precise location of the vehicle; however, GPS signals can easily be blocked, jammed, or spoofed. These signals can be blocked by canyons or tall buildings. Additionally, adversaries can transmit signals that either make GPS signals difficult to interpret or that imitate real GPS signals and cause a navigation system to think it is somewhere other than its true location. GPS-denied (GPS-D) navigation is the process of navigating in the absence of GPS.

Many methods of performing GPS-D navigation have been proposed and explored. One such method is to use …
