A Framework That Explores The Cognitive Load Of Cs1 Assignments Using Pausing Behavior, Joshua O. Urry

All Graduate Theses and Dissertations, Fall 2023 to Present

Pausing behavior in introductory Computer Science (CS1) courses has been related to a student’s performance in the course and could be linked to a student’s cognitive load, or assignment difficulty. Having an objective measure of the cognitive load would be beneficial to course instructors as it would help them design assignments that are not too difficult. Two studies are presented in this work. The first study uses Cognitive Load Theory and Vygotsky’s Zone of Proximal Development as a theoretical framework to analyze pause times between keystrokes to better understand what types of assignments need more educational support than others. The …

The Influence Of Individual Strategies On Cougar Ecology: Insights From Predation, Space Use, And Reproduction, Kristin Nicole Engebretsen

All Graduate Theses and Dissertations, Fall 2023 to Present

Carnivores are ecologically important to global ecosystems because they interact with their prey species and other carnivores in a variety of ways. Many carnivores have suffered habitat loss and persecution by humans, which has led some populations to become imperiled or locally extirpated. Despite these challenges, cougars (Puma concolor) continue to exist across North, Central, and South America. They exhibit behavioral adaptation across their wide range, thriving in terrain that ranges from temperate forests, to steppe scrub, to rainforest, to rugged deserts. Across these diverse ecosystems, cougars can successfully establish territories, hunt prey, and raise young to persist …

Online Deception: The Impact Of Language In Text-Based Deception Detection, Stephanie Dayle Avila

All Graduate Theses and Dissertations, Fall 2023 to Present

In today’s digital age, spreading false information online can have serious consequences, from affecting elections to undermining public health efforts. Despite the issue's importance, there’s been relatively little research into better understanding how people make decisions about lies and misinformation online. My project dives into this challenge by exploring how specific language cues, like grammar errors or unusual word choices, influence people’s perception of statements in terms of deceit online. I examined how people react to these cues through three separate but related studies when reading truthful and deceptive statements. The first two studies showed that true statements with grammatical …

Informing Control Efforts For A Prolific Invasive Species: Characterizing Common Carp Spatio-Temporal Distribution And Evaluating The Impacts Of Gear Selectivity In Utah Lake, Rae Fadlovich

All Graduate Theses and Dissertations, Fall 2023 to Present

Management programs that aim to reduce the consequences of invasive species are often challenged by populations that can rapidly recover from removal efforts. Selectivity, the relative impact of harvest on different size classes, can contribute to population recovery when younger fish are not effectively targeted. In Utah Lake, the location of one of the world’s largest freshwater fish control programs, managers have been attempting to control the common carp (Cyprinus carpio, hereafter “carp”) population since 2009 but efforts have been hindered by the use of selective fishing gears. I conducted a lake-wide field study to gain insights into …

Ianova: Multi-Sample Means Comparisons For Imprecise Interval Data, Zachary Rios

All Graduate Theses and Dissertations, Fall 2023 to Present

In recent years, interval data has become an increasingly popular tool to solve modern data problems. Intervals are now often used for dimensionality reduction, data aggregation, privacy censorship, and quantifying awareness of various uncertainties. Among many statistical methods that are being studied and developed for interval data, the significance test is particularly of importance due to its fundamental value both in theory and practice. The difficulty in developing such tests mainly lies in the fact that the concept of normality does not extend naturally to interval data (due the range of an interval being necessarily non-negative), causing the exact tests …

Nutrient Management Of Cannabis In Controlled Environments, Julie A. Hershkowitz

All Graduate Theses and Dissertations, Fall 2023 to Present

Cannabis has been cultivated for millennia as a multipurpose crop for food, fiber, and medicine. Secondary metabolites called cannabinoids, including cannabidiol (CBD) and the psychoactive Δ-9 tetrahydrocannabinol (Δ-9 THC), are responsible for the medicinal properties of cannabis. The intoxicating nature of THC resulted in legislation prohibiting the possession and production of cannabis within the United States during the 20^th century. As a result, research programs on cannabis production were halted at most institutions. In recent years, cannabis production has become widespread within the US as a result of increasing legalization. However, modern cannabis production nutrient management programs often include …

El Nino Prediction At 1- And 3- Year Lead Times Driven By The Western North Pacific Precursor And Their Impacts, Krishna Borhara

All Graduate Theses and Dissertations, Fall 2023 to Present

The El Niño–Southern Oscillation (ENSO) is a climate variability characterized by fluctuations in the atmospheric and upper ocean conditions of the tropical Pacific Ocean that result in either warmer- or colder-than-average sea surface temperatures (SST) in the tropical eastern Pacific. These changes cause variations in weather and climate in distant locations through large-scale atmospheric circulation patterns. These variations often manifest in form of adverse effects or extremes such as heat waves, droughts, or floods, making efforts towards improving ENSO prediction critical in mitigating its impact on various sectors. This dissertation focuses on how interactions between the atmosphere and ocean in …

Novel Kinetic Description Of Real-Time Polymerase Chain Reaction Characterizes Interrelated Effects Of Sample, Master Mix, And Cycle Time, David Tafur

All Graduate Theses and Dissertations, Fall 2023 to Present

Real-time quantitative polymerase chain reaction fluorescent curves are influenced by the quantification method, template length, primer sequence, polymerase activity, reaction conditions, and unwanted side reactions. Interpretation of these curves depends on understanding the subjacent mechanisms by which those factors can alter the curve profile, particularly on highly diluted analytes or impure samples. However, such factors are individually described today, or their interplay is not fully developed. The present work examines the effect of primer dimer formation and extension, resource competition, template reannealing, and polymerase thermodegradation, in addition to novel descriptions of polymerase competitive inhibition, extended primer amplification, and the probability …

Processes For Improved Variable Rate Irrigation And Nitrogen Within Potato-Wheat-Wheat Cropping Systems, Elisa A. Flint

All Graduate Theses and Dissertations, Fall 2023 to Present

Proper irrigation and nutrient management are vital for optimal crop production within agricultural fields. Improving irrigation and nutrient application through precision agriculture is necessary to conserve the limited resources available, while improving yield and quality of crops produced through such a system. Variable rate irrigation (VRI) and variable rate nitrogen are systems used to apply water and nitrogen more precisely to agricultural fields to reduce runoff, deep percolation, leaching, and other negative impacts of over application, while providing the optimal rates to produce maximum yields. However, the processes to utilize these systems have proven to be more difficult than expected, …

An Expansive Framing Intervention And Its Influence On Nursing Students' Perceptions Of Value For Mathematics, Kimberly Evagelatos Beck

All Graduate Theses and Dissertations, Fall 2023 to Present

Nurses regularly use mathematics on the job, yet they often do not view their work as mathematical. This may indicate a lack of transfer from the nursing school mathematics context to nursing practice. Further, nursing students often perceive very little usefulness and relevance for learning mathematics beyond simple calculations. Expansive Framing (EF) is a theory and instructional technique that has been shown to foster transfer by establishing intercontextuality, or connections made between disparate contexts. This research explored whether creating intercontextuality created through broad framing also improved perceptions of mathematics value and transferability, and how intercontextuality functioned as the driver of …

Using An Interactive Computer Training To Train Teachers In Function-Based Assessment And Intervention, Kristin R. Griffith

All Graduate Theses and Dissertations, Fall 2023 to Present

Since many educators receive little-to-no formal training in evidence-based classroom management strategies, it may be helpful to train general education teachers in strategies that direct them to the underlying causes of problem behavior. One such strategy is functional behavior assessment, which is the process of gathering information to determine the function of problem behavior, or why behavior is occurring. One potentially effective way of training teachers in this process may be to use an interactive computer training, which has previously been used to train a variety of complex behavior analytic skills with other populations. In the current study, we trained …

“Singular And Beautiful City”: Nineteenth Century English Travel Literature And Venice, John Sheehan

All Graduate Reports and Creative Projects, Fall 2023 to Present

Joseph Mallord William Turner was one of England’s most noteworthy artists in the early nineteenth century. Turner’s works, which included both domestic and foreign views, are known for expressing light and atmosphere in a unique way unlike other artists of the time. Turner took liberties with the topographic arrangements of the cities and landscapes that he painted, which again differed from many of the artists who preceded him. His foreign works were especially well received by critics and buyers alike in England. In 1815, many English artists including Turner set out for the newly reopened continent, with the intent of …

Objects Of Remembering: Material Culture, Oral Histories, And Historic Sites In Utah's World War Ii Story, Sara Watkins

How Do Immigration And Technological Growth Affect One Another? Providing Guiding Principles For Policymakers, Nate Karren

All Graduate Reports and Creative Projects, Fall 2023 to Present

The relationship between immigration and technological growth is more nuanced than a simple statement of positive or negative correlation. How one affects the other varies depending on the skill level of the immigrant and the field where they work. Conclusions drawn by the literature form patterns that can be used to best understand the relationship between immigration and technology. High-skilled immigration boosts technological development through a complementary relationship, but low-skilled immigration can be a complement or a substitute with technological growth depending on the sector. Policymakers interested in promoting long-term economic growth through technological growth should have a clear picture …
