Understanding Teacher Sense-Making Discourse During Collaborative Professional Development Of An Expansively-Framed Computer Science Curriculum, Courtney Stephens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Elementary school teachers are being increasingly asked to teach computer science—something that most teacher certification programs do not prepare them for. In an attempt to study how elementary teachers learn to teach computer science, I analyzed the ways that teachers behaved during a professional development accompanying the implementation of a fifth-grade computer science curriculum. My findings suggest that teachers benefit from professional development that encourages collaboration and active participation in teachers through discussion and modeling. Furthermore, my findings suggest that teachers benefit from using curriculum that deliberately connects new concepts to content that they are already familiar and comfortable with—a …

Synergistic Effect Of High Intensity Ultrasound, Antimicrobial Compounds, And Uv-A Light On Microbial Quality Of Dairy Products, Bryce Rodney Hales

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Food spoilage and contamination remains a common problem within the food industry. Furthermore, the continued change of consumer demand and perspective on food quality and products has led the food industry and researchers to find new methods of food preservation. Many of these new methods hope to use non-thermal processes since thermal processes tend to decrease the overall quality of the final product. Some new non-thermal methods that have been looked at are the use of high intensity ultrasound (HIU), ultraviolet light, and the use of natural antimicrobials. In this study, UHT milk inoculated with either E. coli K12 or …

When The Desert Meets The Classroom: A Mixed Methods Study On Experiential Learning And Andragogy For Design-Situated Curricula, Julie K. Lamarra

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study’s significance examined how outdoor experience in place can influence students’ designs in the context of outdoor recreation. Historically, experiential education and outdoor education have been used widely across curricula but are not so commonly accepted in design education except in the form of internships. This study sought to examine how being in the place that activity occurs and learning about the cultural aspects of place, activity, and community impacted students’ designs.

This study looked at how existing theories such as Landscapes of Practice and the development of boundaries, knowledge, and identity are formed within communities of practice and …

Fitting Cell-Based Biomechanical Models From Spatiotemporal Data: A Gradient Descent Approach, Namita Raghuvanshi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Biological systems that contain multiple living cells exhibit complex self-organization during development of an embryo as individual cells coordinate their behaviors to form intricate patterns. Understanding the mechanisms that underlie this emergent behavior is within reach because of advances in cell imaging that can now track hundreds of cells’ states and positions in real time. However, computational methods are needed that can fit physical scientific models to these observations in space and time. This work introduces a new method to solve this problem that applies automatic differentiation and gradient descent, techniques that underlie deep-learning advances. The method fits a biomechanical …

Insights On Reticulate Evolution In Ferns, With Special Emphasis On The Genus Ceratopteris, Sylvia P. Kinosian

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The history of life is often viewed as a evenly branching tree; however, in reality it is more like a tangled hedgerow. Many groups of organisms are known to have such a net-like or reticulate evolutionary history, but it is particularly common in ferns and lycophytes (also known as pteridophytes). This dissertation investigates how net-like evolution affects different groups of ferns, with a special emphasis on the model species C-fern (Ceratopteris richardii, also called the antler or water sprite fern). Genomic data are utilized to under-stand hybridization, cryptic species and reticulate evolution in two groups of ferns. The …

Cultural Memory And Media: Spanish Republicans And The Spanish Civil War, Stuart Cameron

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This project examines the interplay between memory, history, and politics relating to Spanish Republican memories of the Spanish Civil War (1936-1939) and the following authoritarian dictatorship of Francisco Franco (1939-1975). In my analysis of this relationship, I focus on the years around the passage of the Law of Historical Memory in 2007; I explore how Spaniards used several forms of media, namely books, graphic narratives, and interviews, to relay their messages regarding the recovery, preservation, and passage of the memories of the defeated Republicans. The authors in each medium, despite telling different stories, both real and fictional, portrayed the act …

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The misalignment between the mathematics taught in high school and the mathematics expected at colleges and universities has created a difficult transition for high school students in the U.S. from high school to college level mathematics. Intelligent Tutoring Systems (ITS) have been used to help high school students transition from the mathematics taught in high school to the mathematics expected at colleges and universities across the country. The purpose of this study was to examine relationships between high school students’ performance in Assessment and LEarning in Knowledge Spaces (ALEKS) Placement, Preparation, and Learning (PPL) Modules and …

3d-Printed Morphing Wings For Controlling Yaw On Flying-Wing Aircraft, Benjamin C. Moulton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The flaps on an airplane wing are used to control the aircraft during flight. These flaps traditionally have at most three articulation or hinge points. Recent studies have shown improved flap efficiency using a conformal flap, which deforms following a curved shape. Much of aircraft improvement comes through increasing its efficiency during flight. This efficiency is generally improved by decreasing the drag force on the aircraft. A potential solution to decrease drag is to remove additional lifting surfaces, such as the horizontal and vertical stabilizer ubiquitous on general aviation aircraft. These additional lifting surfaces are used to trim and control …

Deaths Of Despair In The United States, Amin Etemadifar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Life expectancy is one of the most important indicators of public health and is an indication of overall health status in a population. Thanks to public health and medical advancements over recent decades, the life expectancy of all nations has significantly increased, and that is more true for developed nations like the United States. However, the most recent data shows the longevity of Americans has become stagnant since 2010. So the first question that comes to mind is why that is happening, and the main goal of this dissertation is to answer that question.

In order to address that question, …

Extended Maternal And Paternal Hereditary Risk For Alzheimer’S Disease Examined By Sex In A Sample Of Community Dwelling Older Adults In Cache County, Utah, Elizabeth K. Vernon

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

More than 6 million Americans are living with Alzheimer’s Disease (AD) and this number is expected to rise and surpass 12.7million individuals by the year 2050. Currently there is no cure for the disease and prior research has focused on prevention by identifying risk factors. Known risk factors associated with AD include older age, female sex, genetics, family history of AD, genotype of the apolipoprotein E (APOE) gene, and vascular risk factors (e.g., cholesterol, hypertension) and conditions or events (e.g., CHF, stroke). The effects of many of the above risk factors have differed in men and women, but few studies …

Nitrogen Fertilizer Showed Little Effect On First- And Second-Year Corn Yield And Quality Following Alfalfa, Bailey Brent Shaffer

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Silage corn (Zea mays L.) following alfalfa (Medicago sativa L.) is a common crop rotation in Utah and southern Idaho. This is done, in part, to take advantage of residual nitrogen (N) fixed by bacteria that work in symbiosis with the roots of alfalfa. After alfalfa is terminated, much of the N that was fixed by the plant is released into the soil and becomes available for use by the rotational crop. This reduces the amount of N fertilizer that growers need to apply. The Utah Fertilizer Guide currently recommends an N credit to a rotational crop following …

Safety In Numbers: Models Of Pedestrian And Bicycle Crash Frequency And Severity At Signalized Intersections In Utah Using Innovative Measure Of Exposure, Ahadul Islam

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Recent trends indicate a dramatic increase in both the number and share of pedestrian and bicyclist injuries and fatalities nationally and in many states. This study aimed at understanding (geometric, traffic, operational, and other) factors associated with pedestrian and bicycle safety and also to assist in the prioritization and selection of countermeasures to improve pedestrian and bicycle safety at signalized intersections. Several negative binomial models were estimated to investigate factors affecting pedestrian and bicycle crash frequency. The models suggested several characteristics of the road network, land use, built environment, and neighborhood sociodemographics were significantly associated with more (or fewer) pedestrian …

Don't Get Me Started About The Water: Foodways And Power In Juvenal's Satire V, Alex Reese

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Don’t Get Me Started About the Water analyzes the food in the dinner of Juvenal’s fifth satire from the perspective of Roman foodways in the first and second centuries. This analysis provides a surprising conclusion: although the guest and host are served dishes differing vastly in quality, neither man gets a nutritious meal. This follows with arguments elsewhere in the Satires, namely that Rome itself kills its occupants and the best course of action is to abandon the city for the countryside.

Metaxmorph: Hierarchical Transformation Of Data With Metadata, Shubham Airan

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This research is about transforming data. Data comes in different shapes; it can be structured as a graph, a tree, a collection of tables, or some other shape. In this thesis, we focus on data structured as a tree, which is known as hierarchical data. The same data could be structured in many different tree shapes. Previously it was shown how to transform data from one tree shape, one hierarchy to another without losing any information. But sometimes the pieces of the hierarchy are annotated or associated with metadata, that is, with data about the data itself. The metadata can …

The Effect Of A Narrative Intervention On The Production Of Complex Utterances By Children At-Risk For Language Disorders, Rebekah Wada

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The ability to produce complex sentences with a variety of complex clauses is essential for children’s academic success in topics such as science and language arts. Previous research suggests that improving children’s ability to create narratives (stories) results in increased use of sentences with multiple clauses. This study examined the effect of the Supporting Knowledge in Language and Literacy (SKILL) narrative intervention on participant’s use of complex sentences. Participants were 120 monolingual English speakers between the ages of 8;0 and 10;11 who participated in a larger randomized control trial. Participants were randomly assigned to the treatment group or the control …

The researcher collected online responses from 409 adolescents between the ages of 13-17 years old concerning their social media use and psychological well-being.

Variables in the research included time spent on social media, number of platforms used, active use, parental mediation, and emotional connection. The two variables that had a statistically significant relationship with psychological well-being included parental mediation and emotional connection to social media.

Recommendations for continued research could include …

Sexual Prejudice, Sexism, And Religion, Chana Etengoff, G. Tyler Lefevor

Psychology Faculty Publications

Multi-national and meta-analytic studies suggest that the pathways between religiousness and sexism/sexual prejudice are partially mediated by sociopersonality factors such as conservatism. In this article, we describe the contributing factors to this relationship, such as authoritarianism and fundamentalism. These factors interact at the dynamic nexus of individual and social development. As such, religiously situated sexism and sexual prejudice are not viewed as inevitable outcomes to religious practice and faith. Individual differences (e.g. conservatism), congregational (e.g. doctrine/policies, limited contact), and cultural factors (e.g. power hierarchies) mutually contribute to this landscape, and individuals ultimately make choices regarding their behavior and views. Further …

The Wingate Anaerobic Test: A Comprehensive Literature Review And Update On Reference Values In Athletes, Caleb Christie

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The Wingate Anaerobic test (WAnT) was developed in the 1970s as a measurement of lower extremity anaerobic power (Ayalon, Inbar, Bar-Or, 1974) and has long been used as a measurement tool in athletes, who are often defined by numbers. While numbers are not able to entirely predict or evaluate athletic ability, they are often used as a tool to predict or rate athletes. The WAnT has long been a gold standard in evaluating lower extremity power, which is a highly valuable aspect of many sprint and power-driven sports (e.g., hockey, football, or track and field). The WAnT was originally developed …

A Research Project To Investigate The Instructional Preferences Of Alternatively Certified Career And Technical Education Teachers, Jessica Deceuster

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Industry career workers that have transitioned to teaching within the education sector have the knowledge base to develop “what” needs to be taught in Career and Technical Education (CTE) curriculum; however, they do not have adequate knowledge about instructional strategies or “how” the curriculum content should be taught. Therefore, the purpose of this project is to document the instructional strategies, techniques, and coursework that were taught through the Utah State University Career and Technical Education Academy, to Career and Technical Education teachers that have transitioned from industry to education, and to assess how well the instructional strategies, techniques, and coursework …

Exploring Questions Of Tectonic Geomorphology In The Bear River Range, Utah Using Terrain Analysis And Reconstruction, Edward M. Grasinger

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Despite a long tradition of geologic studies in the region surrounding Utah State University, there remain unexplored questions and unutilized approaches for understanding the landscape evolution of the Bear River Range. A large-scale reconstruction of the East Cache fault system can be useful in estimating the total displacement of the fault, its geologic longevity, and total energy involved. Likewise, an analysis of reach-scale features of the Logan River can explore how tectonics and bedrock type affect the patterns and history of the river. Geographic Information Systems (GIS) software is useful in reconstructing, visualizing, and measuring such geomorphological features and changes …

Test-Retest Of The 5-Minute Psychomotor Vigilance Test, Katharine Dennison

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this study was to evaluate the reliability of many variables in the 5-minute Psychomotor Vigilance Test (PVT). Many studies have looked at the validity of a 5-minute PVT, but few so far have looked at reliability. For this study, 13 adult females who worked 12-hr shifts were recruited to complete a two trial day study. The first trial day, the subjects submitted health questionnaire followed by a self-reported sleepiness scale and then a 5-minute PVT. The second trial session the subjects only competed the sleepiness scale followed by the 5-minute PVT. After analyzing the data, it was …

Methane Emission Treatment And Potential Upcycling Using Methylomicrobium Alcaliphilum, Jace Parkinson

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Anthropogenic methane emissions are harmful to the environment and can be difficult to treat. Use of M. alcaliphilum for bioremediation of methane looks to be one of the most promising methods of reducing the negative environmental impacts of methane emissions while simultaneously providing an economic incentive. Successful bioreactor design for M. alcaliphilum based methane treatment requires biokinetic constants and microbial growth information. Methods were established for determining biokinetic constants, including growth rate, biomass yield, specific methane consumption rate, and a correlation between methane oxidation and carbon dioxide production for M. alcaliphilum. Values determined for these constants were used to …

Marey Sue: Perpetuating Mary Sue Stereotype In The Star Wars Trilogy, Samantha Wiser

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

My Plan B thesis addresses the gendered portrayal of the female character Rey in the most recent three Star Wars films released between 2015 and 2019. The latest trilogy is comprised of The Force Awakens, The Last Jedi, and The Rise of Skywalker. These films present the character Rey, who brings many firsts to the series. She is the first woman to be the central character in a Star Wars trilogy, she is the first woman to use the Force, and she is also the first woman to wield a lightsaber. Despite her firsts, Rey still draws criticism for …

A Teacher's Guide In Creating Linguistic Diverse Classroom: Code-Meshing And Translingual Practice In First-Year Composition, Yvonne Liu

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

This thesis and portfolio are inspired by the recent code-meshing pedagogy movement to promote linguistic justice in the composition classroom along with the author’s personal journey in English learning. The traditional, monolingual practice in the composition classroom often isolates international students who have multilingual abilities above the rest of the students. The idea that there is only one correct use of English—standard English—assumes that one type of English is better than others. However, most native speakers cannot explain the rules and mechanism of standard English, which leaves international students often feeling frustrated and lowers their confidence in English writing and …

Current Expected Credit Losses Methodology, Rhett Crandall

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The purpose of this paper is to implement the Current Expected Credit Losses (CECL) methodology for an Association of the Farm Credit System (FCS). CECL was released in 2016 by the Financial Accounting Standards Board (FASB) and is expected to be implemented by all banks and lending institutions starting Jan. 1, 2023. CECL changes the way lenders account for Allowance for Loan and Lease Losses (ALLL) by allocating a small amount of allowance for loan loss for each loan at origination. The association for which this project was designed provided historical loan data for 21,755 loans which tracked probability of …

Covid-19 Outcomes And The Incidence Of Slavery, Amanda Ortega

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Environmental factors have been shown to correlate with COVID-19 outcomes. This study advances the literature on health economics by examining the importance of socioeconomic factors. In addition to standard economic factors, I consider the relationship between the past incidence of slavery and COVID-19 outcomes. I analyze county-level U.S. Census data and Georgia Department of Public Health county-level COVID-19 data using regression analysis. I find that the Covid-19 county vaccination rate in Georgia is related to 1860 slave concentration. No statistically significant relationship is found between 1860 slave concentration and COVID-19 death rate, case rate, or vaccination rate when health, socioeconomic, …

No Evidence Of Stochastic Resonance In Postural Sway Response To Noisy Galvanic Vestibular Stimulation In Healthy Young Adults, Dominique Rice

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

The transcutaneous application of a sub-sensory electrical stimulation to the vestibular afferents, known as noisy galvanic vestibular stimulation (nGVS), is thought to cause a reduction in postural sway at optimal amplitude intensities due to a mechanism known as stochastic resonance (SR). SR is a phenomenon whereby the addition of low amplitude noise to a non-linear system can be beneficial rather than detrimental. In humans, behavioral markers of SR in postural sway have been inconsistent, potentially due to insufficient power or false positives. Therefore, the main purpose of this study was to determine whether the frequency of observing SR-like effects improves …
