An Assessment Tool To Analyze Code Written In App Inventor, Rohit Gopalan

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

Assessment plays a significant role in today’s educational field. When creating an assessment tool, we should keep in mind that the tool measures learning, supports learning and encourages learning. Many assessment tools are available in the educational market such as Dr. Scratch, FCS1 Assessment Instrument, and Beyond the rubric. These tools help teachers to evaluate students’ performance in programming activities, but they do not completely measure the creativity shown by students in programming. For example, Dr. Scratch measures abstraction, problem decomposition, and parallelism. FCS1 Assessment Instrument measures a set of foundational computer science concepts like variables, loops, and arrays. It …

Synthetic, Julia L. Prince

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

Throughout her life, the poet May Swenson concerned herself with communicating pathways to personal improvement and self-discovery by navigating the distinct social and psychological challenges specific to her historical context, personality, and gender. Though deceased, Swenson is still able to communicate these notions successfully, as many of her poems’ speakers do not conceal their intentions, but rather “force the truth.”

Synthetic, a poetry chapbook, similarly “forces the truth,” as the speaker – like Swenson’s – craves to bare all and discover more about who she is, as she contends with her own social and psychological challenges regarding beauty-gestures, practices, …

Hellhounds And Helpful Ghost Dogs: Conflicting Perceptions Of “Man’S Best Friend” Encoded In Supernatural Narrative, Kiersten Carr

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

Black dogs are a type of spectral entity that, according to legend, have been haunting the British Isles for centuries. While the legends have many regional variations, the common feature remains a large black dog, often with eyes “large as saucers” or sometimes, flaming, who appears and then disappears, often without a trace. In many of the legends, the black dog is malevolent: assaulting travelers, frightening livestock to death, attacking other dogs, haunting graveyards and gibbets, and heralding death or disaster. In other versions, however, the black dog acts as a protector to those in need, warding off disaster with …

Financial Outcomes From Selection Of Insurance Intervals, Shana Anderson Stewart

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

The purpose of this paper is to demonstrate the potential value of enrolling in rainfall-index for pasture, rangeland, and forage insurance for Utah producers. A stochastic optimization model is used to identify the optimal selection of insurance intervals that will provide the maximum indemnity payments less premiums. Four Utah counties were selected for analysis. Results indicate that positive returns will occur greater than 60% of the time in all counties with the selected insurance intervals. The optimal months to insure varied in each county.

Calculating The Cohomology Of A Lie Algebra Using Maple And The Serre Hochschild Spectral Sequence, Jacob Kullberg

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

Lie algebra cohomology is an important tool in many branches of mathematics. It is used in the Topology of homogeneous spaces, Deformation theory, and Extension theory. There exists extensive theory for calculating the cohomology of semi simple Lie algebras, but more tools are needed for calculating the cohomology of general Lie algebras. To calculate the cohomology of general Lie algebras, I used the symbolic software program called Maple. I wrote software to calculate the cohomology in several different ways. I wrote several programs to calculate the cohomology directly. This proved to be computationally expensive as the number of differential forms …

Lobbying Legislation And Cumulative Abnormal Returns, Brenan Stewart

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

The Honest Leadership and Open Government Act of 2007 (Pub.L. 110-81, 121 Stat. 735, enacted September 14, 2007) was passed by the U.S. Congress in order “to strengthen public disclosure requirements concerning lobbying activity and funding. It placed more restrictions on gifts for members of Congress and their staff, and provides for mandatory disclosure of earmarks in expenditure bills.” Treating this event as a natural experiment, we examine how this legislation affected the Cumulative Abnormal Returns (CARs) of firms that lobbied in the year(s) leading up to the passing of the legislation. We find that companies that lobbied in the …

Two Cases Of Intellectual Continuity Between Mental Philosophy And Psychology: William James And Charles Grandison Finney, Zachary Zschaechner

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

The history of American psychology was once dominated by a narrative that emphasized the unprecedented nature of psychology at the expense of its relation to mental philosophy. Contrary to this narrative, this discussion offers two cases of intellectual continuity between 19th century Protestant mental philosophy and the new psychology as it emerged in the United States in the last quarter of the 19th century.

Rfviz: An Interactive Visualization Package For Random Forests In R, Christopher Beckett

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

Random forests are very popular tools for predictive analysis and data science. They work for both classification (where there is a categorical response variable) and regression (where the response is continuous). Random forests provide proximities, and both local and global measures of variable importance. However, these quantities require special tools to be effectively used to interpret the forest. Rfviz is a sophisticated interactive visualization package and toolkit in R, specially designed for interpreting the results of a random forest in a user-friendly way. Rfviz uses a recently developed R package (loon) from the Comprehensive R Archive Network (CRAN) to create …

The Free Cash Flow And Corporate Returns, Sen Na

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

Mcpherson (2018) and Jose, Lancaster, Stevens (1996) have written papers to examine the relationship between liquidity management and firm profitability. The literature establishes that the cash conversion cycle has an implication for the profitability and liquidity of a firm. We extend the time period and analyze the free cash flow instead of cash conversion cycle. We provide evidence that firms with higher free cash flows have higher risk adjusted stock returns.

Production And Biocompatibility Of Spider Silk Proteins In Goat Milk, Richard E. Decker Jr

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Due to its strength, flexibility, and biocompatibility, spider silk is a highly appealing material for applications in the medical field. Unfortunately, natural spider silk is difficult to obtain in large quantities because spiders are territorial and cannibalistic, making them impractical to farm. Synthetic spider silk proteins produced by transgenic hosts such as bacteria and goats have made it possible to obtain the quantities of spider silk needed to study it more fully and to investigate its potential uses. The spider silk proteins produced in our laboratory do not have an optimal purification method to remove all of the non-biocompatible contaminants …

Autonomous Trajectory Planning For Satellite Rpo And Safety Of Flight Using Convex Optimization, Nicholas G. Ortolano

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Optimal trajectory planning methods that implement convex optimization techniques are applied to the area of satellite rendezvous and proximity operations. This involves the development of linearized relative orbital motion dynamics and constraints for two satellites, where one maintains a near-circular reference orbit. The result is formulated as a convex optimization problem, where the objective is to minimize the amount of fuel required to transfer from a given initial condition to the desired final conditions. A traditional rendezvous and proximity operations scenario is analyzed, which includes examples of initial approach, inspection, final approach, and docking trajectories. This scenario may include trajectory …

Improving Accuracy Of The Edgebox Approach, Kamna Yadav

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Object region detection plays a vital role in many domains ranging from self-driving cars to lane detection, which heavily involves the task of object detection. Improving the performance of object region detection approaches is of great importance and therefore is an active ongoing research in Computer Vision. Traditional sliding window paradigm has been widely used to identify hundreds of thousands of windows (covering different scales, angles, and aspect ratios for objects) before the classification step. However, it is not only computationally expensive but also produces relatively low accuracy in terms of the classifier output by providing many negative samples. Object …

Dayananda Saraswati And The Colonial Machines: Vedic Reformation, European Science, And Modernity In Colonial India, David Tauber

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

The relationship between European science and religion has varied considerably through time and among different traditions. This monograph attempts to catalogue one such variant by exploring the context entrance of European science into the Indian subcontinent, at the beginning of the British colonial period, by focusing on how a single religion leader drew upon European notions of science in building his reformed Vedic theology. Dayananda Saraswati (1824-83) spent much of his life traveling northern India as an itinerate ascetic and ultimately founded an intellectual lineage that was instrumental in the Indian Independence movement. Despite having no formal British education included …

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

Purpose: Conversational entrainment describes the tendency for individuals to align their behavior with their communication partners and is essential for successful interaction. Evidence of entrainment in adults is robust, yet research regarding its development is sparse. Here, we investigate the effectiveness of a quasi-conversational paradigm for the purpose of identifying the speech rate entrainment abilities of children.

Method: Data were collected from a total of 50 typically developing children from 5-14 years old. Participants completed an entrainment task to identify the presence of speech rate modification depending on the presence of “fast” or “slow” stimuli. The entrainment task utilized a …

Inter-Laminar Fracture Of 3d-Printed Plastics - Development Of Methods, Christopher Stolinski

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

Due to the increased use of 3D printed acrylonitrile butadiene styrene (ABS) plastic parts, a way to quantify the failure energy (energy needed to initiate cracking) is needed. Impact tests at high rates of loading are performed to determine failure energy. Throughout testing, specimens are monitored with high speed cameras to perform camera-based deformation measurements. Data acquisition and processing methods to calculate failure energy using crack opening displacement, and loading rates are developed to enable further use by Dr. Ryan Berke’s lab at Utah State University.

Using 3-D printed thermoplastic materials, hybrid rocket fuel grains can be printed with nearly any cross-sectional shape, and embedded cavities are easily achieved. Applying this technology to print fuel materials directly into a CubeSat frame results in an efficient, cost-effective alternative to existing CubeSat propulsion systems. Different 3-D printed materials and geometries were evaluated for their performance as propellants and as structural elements. Prototype "thrust columns" with embedded fuel ports were printed from a combination of acrylonitrile utadiene styrene (ABS) and …

Interactions Between Fire Severity And Forest Biota In The Central Sierra Nevada: Formation And Impact Of Small-Scale Fire Refugia And The Effect Of Fire On Forest Structure Predictive Of Fisher (Pekania Pennanti) Den Habitat, Erika M. Blomdahl

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Fire is a natural and essential component of forests in western North America. Fire maintains biodiversity through the creation of different habitat types, and regular fire rotations reduce the accumulation of woody fuels and thick understory plant densities that give rise to catastrophic fire. The practice of fire exclusion has altered western forests and increased the risk of widespread change under rising temperatures projected for the 21^st century. To manage for the reintroduction of fire it is critical that we understand the interactions between fire and forest biota in recently fire-suppressed forests.

In Chapter 2, I studied the formation …

Experimental Investigation Of A Green Hybrid Thruster Using A Moderately Enriched Compressed Air As The Oxidizer, Marc Anthony Bulcher

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A hybrid rocket is a propulsion system that uses propellants in two different phases, typically a solid fuel inside the combustion chamber and a separate gaseous or liquid oxidizer stored in a tank. Hybrid rockets are an area of research interest because of their low explosive risk, inexpensive components, and high degree of reliability. In the Propulsion Research Laboratory at Utah State University, pure oxygen is among the top choice for hybrid rocket oxidizers due to its low cost and ease of storage.

Comparing The Predictive Power Of Executive Function Assessment Strategies On Preschool Mathematics Performance, Jacob A. Esplin

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

A child’s executive function (aspects: working memory, response inhibition, and set-shifting between sets of rules) capabilities have been found to strongly relate to their mathematics skills. However, while the relationship has been strongly supported by researchers, a consensus has not been reached regarding the specifics of the relationship between executive function and math skills, including which executive function aspect is most predictive of mathematical performance and the differences in said relationship that might be found when examining both numeracy, such as counting skills and basic operations, and geometry skills. The lack of consensus may be in part because researchers have …

Exploring The Moderating Effect Of Cognitive Autonomy On The Relationship Between Cognitive Distortions And Youth’S Externalizing Behaviors, Liam J. Fischback

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Scholars have connected cognitive distortions to adolescents’ externalizing behaviors. Other scholars have offered that higher levels of cognitive autonomy, which develops during adolescence, may be a protective factor for problem behaviors in adolescence. To date, no studies have explored how these two cognitive processes function and potentially interact to predict adolescent problem behaviors. This study’s purpose was to see if cognitive autonomy affected the relationship between cognitive distortions and externalizing behaviors in a clinical population of adolescents. Past research has suggested that cognitive distortions are greater and more prevalent in clinical populations. Because of this, the processes of cognitive autonomy …

Production And Purification Of Synthetic Minor Ampullate Silk Proteins, Danielle A. Gaztambide

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Spider silks are incredible natural materials that have a wide variety of properties that can rival or outperform even common synthetic materials like Nylon and Kevlar. As nature’s architects, orb-weaving spiders spin seven different silks that are used for very specific roles throughout the spider’s lifecycle. These silks are comprised of proteins called spidroins. Each of these spidroins has evolved to have properties such as strength and/or stretch that make these silks successful and highly adapted in their designated roles in web construction, prey capture and reproduction.

This study involves the production of minor ampullate silk by genetically modifying the …
