A Single-Case Experimental Investigation Of Sketch And Speak Expository Intervention For Adolescents With Language-Related Learning Disabilities Via Telepractice, Amy K. Peterson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study investigated the effects of Sketch and Speak expository language intervention for adolescent students with language-related learning disabilities (LLD). Students with LLD have trouble understanding and using academic language for reading and writing and often benefit from explicit instruction in these areas. Sketch and Speak is an expository language intervention that teaches students to take notes in two forms and to systematically use oral practice to facilitate understanding and memory of notes. First, students learn to take notes using simple sketch writing, or pictography, which allows them to focus on the ideas of the text rather than the spelling, …

Passage Probability Of Woody Debris Elements And Accumulations At I- And V-Shaped Rock Weirs, Kathryn Margetts

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The transport and accumulation of driftwood or large woody debris (LWD) in mountain streams is a natural part of catchment health and river connectivity. At hydraulic structures, the presence of LWD may impact flow efficiency and influence upstream water depth. LWD has been studied at a variety of spillways and weir types, however, little is known about its interaction at rock weirs. This study investigated factors affecting the passage of individual LWD elements and any LWD accumulations at rock weirs, as well as potential impacts upstream of LWD accumulations through field-informed scaled model testing. Observations of LWD at rock weirs …

Stewards And Conservationists: Merging Moral Norms And The Theory Of Planned Behavior To Understand Altruistic Conservation Behavior Among Hunters In Southwestern Utah, Jacob C. Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The leading cause of mortality in California Condors (condors) is lead poisoning, which occurs when condors ingest lead-based ammunition left in carcasses. As a critically endangered species with approximately 115 individuals remaining in the American southwest, increasing the adoption of non-lead ammunition is essential to the recovery of the species. In Utah, the Division of Wildlife Resources (DWR) uses communication with hunters as the primary tool for increasing the adoption of non-lead ammunition in southwestern Utah. In this research, we use social science theory and data collected from a survey of hunters throughout the region to develop a strategic communication …

Investigating Factors That Impact Income Generation And Distribution In Western National Park Gateway Communities, Elizabeth Depew

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Many rural towns in the western united states have come to be defined by high levels of tourism, seasonal residents, and migration driven by the desire to be close to natural amenities and the higher quality of life they afford. This shift is especially apparent in communities that are “gateways” to natural amenities such as national parks. Embracing this shift towards the “New West,” many community planners have heralded amenity-led development as a remedy to the waning feasibility of relying on agriculture and extractive industries. However, anecdotal evidence and several case studies indicate the factors which make these gateway communities …

Natural And Experimental Slow Slip Observed Along Shallow Hematite Faults, Alexandra A. Dimonte

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fault slip relieves stress in the shallow crust by slipping suddenly during earthquakes, but some faults also slip slowly in between earthquakes. Exhumed faults, brought up to the Earth’s surface from depth, preserve a record of fault processes and slip rates informed by fault rock structures, textures, and chemistry. Hematite, a common iron oxide mineral that precipitates on fault surfaces, exhibits crystal textures that potentially indicate past slip rate. Hematite can be dated using the radioisotopic system of (U-Th)/He thermochronometry, which constrains the time when He is trapped within a crystal, a process that is a function of temperature. Exhumed …

Programming Process, Patterns And Behaviors: Insights From Keystroke Analysis Of Cs1 Students, Raj Shrestha

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With all the experiences and knowledge, I take programming as granted. But learning to program is still difficult for a lot of introductory programming students. This is also one of the major reasons for a high attrition rate in CS1 courses. If instructors were able to identify struggling students then effective interventions can be taken to help them. This thesis is a research done on programming process data that can be collected non-intrusively from CS1 students when they are programming. The data and their findings can be leveraged in understanding students’ thought process, detecting patterns and identifying behaviors that could …

Developing Cultural Competence Among Sixth-Grade Students Through Indigenous Knowledge And Place-Based Education, Tyus Roanhorse

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There is a need to develop cultural competence in educational settings. While there is a focus on training K-12 educators to be culturally competent, there is little focus on developing and examining the impact of student cultural competence training. Integrating Indigenous knowledge in an education setting is a unique way to start developing cultural competency by recognizing cross-cultural worldviews and perspectives. This can be done while using place-based education, which links the classroom to the cultural environment that has significant meaning to Indigenous peoples while enriching the learning experience for all students. The current study examines and measures the development …

Holocene Chronostratigraphy Of Dune Fields In Southern Utah: Geomorphic Record Of Past Aridity In The Central Colorado Plateau, Harriet S. Cornachione

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The southwestern United States is characterized by dry climate, and droughts are common. The region is currently in an extreme drought that began in 2000 CE and has lasted longer than any previous drought in at least 500 years. Models predict greater future climate extremes under human-caused climate change. Understanding of the natural range of climate variability is important to put these changes in context. Sedimentary archives of past sand dune activity can help extend the available instrumental observations (last century) and tree-ring records (last millennium).

Sand dunes are landforms that are sensitive to aridity and decreased vegetation cover. They …

Spatiotemporal Data Augmentation Of Modis-Landsat Water Bodies Using Generative Adversarial Networks, Ashit Neema

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The monitoring of the shape and area of a water body is an essential component for many Earth science and Hydrological applications. For this purpose, these applications require remote sensing data which provides accurate analysis of the water bodies. In this thesis the same is being attempted, first, a model is created that can map the information from one kind of satellite that captures the data from a distance of 500m to another data that is captured by a different satellite at a distance of 30m. To achieve this, we first collected the data from both of the satellites and …

Masculinity, Affirmations, Belongingness, And Resiliency In Male Adolescents: Effects On School Engagement, Kelsey Burt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study focused on male adolescent students within 7^th and 8^th grade and how endorsement of masculine stereotypes impacts their school engagement and feelings of belonging. The study also examines how peers maintain masculine conformity and how individual resiliency change outcomes. This research is based on two main theories, inclusive masculinity and social learning theory. These theories describe how behaviors are largely learned from the social environment and maintained due to reinforcement or punishment. There were 127 adolescent males who participated in this study and were recruited through an online survey system. Results of the study show that …

The Working Man's Rendezvous, Tameron Gentry Raines Williams

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The mountain men—fur traders of the Rocky Mountain trade between 1822-1840—are prominent in the history of the American West. Their adventures and exploits have been told and retold as their legend grew as did the myth surrounding their lives. This thesis seeks to dismantle that myth through focused study on the conditions of fur trapping work, the interactions between mountain men and Indigenous tribes of the region, and the role of lesser-known Black fur trappers.

Using The Reshetikhin-Turaev Link Invariant Approach With Non-Semisimple Categories, Adam Robertson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Invariants of knots and links are useful because they give rise to invariants of 3-manifolds. In particular, combinatorial link invariants give rise to combinatorial invariants of 3-manifolds, which are hard to come by using traditional methods from classical topology. The Reshetikhin–Turaev approach, which is based in quantum topology, develops link invariants using semisimple ribbon categories. However, a large class of algebraically interesting ribbon categories are non-semisimple and so give trivial link invariants via the Reshetikhin–Turaev method. We modify the Reshetikhin–Turaev method to make it suitable for non-semisimple ribbon categories. We discuss explicitly the following three examples: semisimple modules for the …

Upstream Methods For Enhancing Engineered Curcumin Biosynthesis, Caleb D. Barton

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Curcumin is a bright orange compound with myriad applications for human health and wellness. Curcumin occurs naturally in the plant Curcuma longa (commonly known as turmeric) but must be extracted from the roots in an environmentally unfriendly fashion to obtain commercially relevant amounts of the compound. In addition, extraction of curcumin from turmeric spice yields a mixture of various curcuminoids, presenting an issue for isolating it in its pure form and complicating its use in clinical settings.

Heterologous biosynthetic production of curcumin in Escherichia coli has been used extensively as a viable alternative to plant extraction but suffers from poor …

Multidisciplinary Reference Solutions For Performance-Optimized Aircraft Wings With Tailored Aerodynamic Load Distributions, Jeffrey D. Taylor

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Morphing wings, or wings that can change shape during flight, have the potential to substantially reduce the amount of fuel consumed by an aircraft over the course of its flight. However, the extent to which these wings can reduce fuel consumption depends on the design of the wing, including its aerodynamic efficiency and its structural layout, and how the aircraft flies, including its flight altitude and speed. Correctly predicting how these design and operational characteristics interact is critical to predicting how wing morphing may affect aircraft fuel consumption. Many computer prediction tools exist that include the effects of these interactions, …

Evaluating The Use Of Inclusive Teaching Materials For Learners With Autism, Juliana Aguilar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the last decade, the field of applied behavior analysis (ABA) has committed to working on diversity, equity, and inclusion (DEI). The work began with call-to-action papers, empirical work on cultural accommodations, and most recently, the certifying board has changed the professional standards for board-certified behavior analysts (BCBAs). An objective and measurable step that BCBAs can take to adhere to the new ethical and professional standards is to use inclusive teaching materials. Inclusive teaching materials are teaching materials that reflect the diversity of society. This study compared the rate of learning and generalization between an inclusive and non-inclusive set of …

The Bray Schools And Black Education In The Early American Republic, Mitchell Allen Fellows

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Ideas about the role of education in American society were contentious during the early years of the Nation. Despite this discord, the vast majority of African Americans lacked access to educational opportunities regardless of whether they were free or enslaved. When schools for African Americans did exist, they were often established by local community leaders or by benevolent societies. Benevolent societies in the early United States existed to prevent what they perceived as a moral decline in the nation. This thesis analyzed the records of schools established by two benevolent societies, the Associates of the Late Dr. Bray and the …

Evaluating The Effectiveness Of A Task Analysis Data Sheet Protocol In Training Educators To Use The You/Me Game During Direct Instruction Reading Groups, Mckenzie Niebergall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Teachers often struggle with classroom management during academic lessons. Self-adapted efforts to improve classroom management are often not founded on researched behavioral principles. These struggles and efforts impact student behavioral and academic outcomes. The You/Me game is a game included in many Direct Instruction curricula, specially sequenced curricula that encourage positive classroom management and the gaining of academic skills, as a means to reward students for correct academic performance. This study examined the effectiveness of providing a sheet of specific written instructions and allowing for clarifying questions in training four general educators to implement the You/Me Game for classroom management …

Comparing Fecal Dna Capture-Recapture Methods To Traditional Mark-Resight Methods For Estimating Abundance Of Mule Deer On Winter Ranges, Andi M. Stewart

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Well-designed monitoring strategies are required to obtain accurate estimates of population abundance, which is important for evaluating conservation and management strategies. Obtaining abundance estimates using traditional survey methods, like aerial surveys, is not possible in all scenarios and can be expensive and risky. One survey method that has gained popularity in the last decade is fecal DNA-based capture-recapture (CMR). However, this method has not been evaluated on winter ranges or in snowy, winter conditions.

My first objective was to implement fecal DNA CMR to estimate abundance of mule deer in the Round Valley and Goodale winter survey areas in the …

Finding Relationships Between Physical Properties Of Butter And Water Loss, Annalisa Jones

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Butter is a desirable fat rich product used for laminated pastries, like croissants, because of its flavor and consumer acceptance. However, butter has some functional aspects that reduce its performance and quality. In manufacturing of butter for laminated pastries, large blocks of butter are pushed through a rectangular opening to form a thin sheet. In this process it is not unusual to see water dripping, indicating water loss in the butter. The purpose of this study was to understand the properties of butter and their role in water loss during processing.

The properties of commercial butters were tested to understand …

Aging Bison Teeth With A Gis: A New Tooth Age Prediction Methodology And Its Archaeological And Ecological Implications, Andrew Edward Owens

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Archaeologists use teeth to estimate the age an animal died based on tooth eruption, growth, and wear. Animal age estimations then inform archaeologists about when and why archaeological sites were occupied. However, to date, no concise and repeatable practice exists to age estimate teeth. Therefore, we propose a new tooth age estimation methodology, in this case using bison teeth. The new tooth aging method uses GIS mapping software to draw tooth surfaces and then calculate tooth surface areas of known-age bison teeth. Then, this known-age tooth sample is used to derive algebraic equations that can estimate the age of prehistoric …

Lentiviral Vector Production At High Cell Density By Transient Transfection Of Suspended Culture Hek Cells, Jacob G. Accordino

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Viral vectors are gene carriers that efficiently deliver therapeutic gene constructs to target cells. Viral vectors are frequently produced in suspension-growing cells of mammalian origin, referred to as packaging cells. Lentiviral vectors have become widely used as gene vectors since they were initially developed two and a half decades ago, particularly in research settings. The advantages of lentiviral vectors for treating diseases of genetic origin have driven research into their large-scale manufacture for clinical settings. Currently, three main challenges exist that limit mass production of lentiviral vectors. First, plasmid DNA used in the production process is very expensive. Second, high …

Pesticide-Leaf Interactions And Their Implications For Pesticide Fate Modeling, Ashlie Kinross

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The work described here provides measured data to improve the understanding of the interaction between a pesticide and leaf surface after application. Two methods were developed, one using a newly introduced instrument, for the extraction of pesticides from leaves. This is required to measure the concentration of pesticide in the leaves. Using one of the developed extraction methods, measurements were made to determine how a pesticide equilibrates between a leaf and the air above it. These measurements were incorporated into a pesticide fate model that predicts how a pesticide moves through the environment after application to an agricultural field. The …

Contributions To Random Forest Variable Importance With Applications In R, Kelvyn K. Bladen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A major focus in statistics is building and improving computational algorithms that can use data to predict a response. Two fundamental camps of research arise from such a goal. The first camp is researching ways to get more accurate predictions. Many sophisticated methods, collectively known as machine learning methods, have been developed for this very purpose. One such method that is widely used across industry and many other areas of investigation is called Random Forests.

The second camp of research is that of improving the interpretability of machine learning methods. This is worthy of attention when analysts desire to optimize …

Many factors influence health; two such factors that warrant additional research include interdisciplinary healthcare teams and food insecurity. These factors may be particularly important among vulnerable populations such as individuals with special healthcare needs, lower income populations, and individuals with disabilities.

Interdisciplinary teamwork promotes improved, and more efficient patient care through the collaboration of healthcare providers in various professional disciplines. Registered Dietitian Nutritionists (RDNs) are experts in the science and application of nutrition, which plays an important role in various disease states. Despite the established need for RDNs on interdisciplinary teams, there is limited research in the interdisciplinary scholarship targeting …

Conservation Genetics Of A Declining Bumble Bee In Western North America; The Influence Of Geography, Dispersal Limitation, And Anthopogenic Activity, Ashley T. Rohde

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Conservation biology addresses the problem of species loss by identifying species in need of protection. Conservation biology has subfields to address different aspects of biodiversity loss, including genetics and sociology. I used genetic approaches to assess the conservation status of western bumble bees, a bumble bee species of conservation concern.

The western bumble bee is a bumble bee species that ranges from Alaska to New Mexico and as far east as Wyoming and Colorado. This species is disappearing in some places. It may soon be listed as endangered in the United States and is already listed as endangered in parts …

An Exploration Of The Relationship Between Interdisciplinary Collaboration And Participation Of Students With Disabilities In Secondary Career And Technical Education, Crystal Kay Emery

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Students with disabilities have been shown to be less ready for college and career when they leave high school than students without disabilities. Secondary transition is the process of a student with disabilities moving from school to post-school settings. Research has shown that participation in career and technical education (CTE) while still in high school for improves the likelihood of meaningful employment after high school for students with disabilities. Research has also shown that collaboration between educators improves academic outcomes for students. Special education (SPED) teachers have extensive training in supporting students with disabilities throughout the education process. Collaboration between …

Redefining Nba Basketball Positions Through Visualization And Mega-Cluster Analysis, Alexander L. Hedquist

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Basketball players have historically been classified based on one of five positions, namely Point Guards, Shooting Guards, Small Forwards, and Centers. While grouping players into these five categories may provide general descriptions of their perceived role, these standard positions fall short of describing players based on their true abilities and performance. This MS thesis proposes a method to group players of the National Basketball Association (NBA) from the past 20 seasons into more meaningful and specific player positions. We systematically group these players into nine distinct categories, and we draw from a vast array of visualization tools, techniques, and software …

Development Of Late-Heading Orchardgrass Germplasm, Megan Marie Getz

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dactylis glomerata L., orchardgrass, is commonly grown with perennial forages such as alfalfa (Medicago sativa L.). However, commercial orchardgrass cultivars currently grown in the Intermountain West generally flower earlier than alfalfa. This results in a reduction in grass nutritional value if harvested to maximize the alfalfa yield, because the two species mature at different rates. Thus, there is a need to better understand the genetic basis of flowering time in orchardgrass and develop late-flowering populations. The objectives of this research were to evaluate the ability to identify and use molecular markers to identify and select late-heading orchardgrass; and to …

An Introduction To Combinatorics Via Cayley's Theorem, Jaylee Willis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In this paper, we explore some of the methods that are often used to solve combinatorial problems by proving Cayley’s theorem on trees in multiple ways. The intended audience of this paper is undergraduate and graduate mathematics students with little to no experience in combinatorics. This paper could also be used as a supplementary text for an undergraduate combinatorics course.
