Shallow Composition And Structure Of The San Gabriel Fault, California In Drill Core And Geophysical Logs: Implications For Fault Slip And Energetics, Kaitlyn A. Crouch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Earthquakes are the sudden and intensive release of energy due to slip along faults. This energy may be felt on the Earth’s surface and may cause displacement of the Earth’s crust (seismic slip). As an earthquake ruptures, rocks in and around the fault are damaged and altered. When a fault displaces without earthquakes, it is referred to as aseismic creep. Faults may experience both seismic slip and aseismic creep throughout their cycles. In order to better model earthquake hazards and understand the cause of seismic slip versus aseismic creep in the shallow crust, we need to characterize the properties of …

A Randomized Controlled Trial On Using Peer-Support Coaching To Improve Adherence To Online Self-Help For College Mental Health, Korena S. Klimczak

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Online self-help programs can serve as accessible mental health resources, allowing users to learn skills for improving their mental health at their own pace. The self-guided nature of these programs allows them to be cost-efficient as compared to traditional therapy and appealing to those who do not want to attend traditional therapy due to stigma or low-perceived need. However, these programs also struggle with low adherence rates, with typically only a small subset of users completing a given program in full. Coaching has been previously explored as a way to increase program adherence, adding a low-intensity human component to self-help …

Refining, Testing, And Applying Thermal Species Distribution Models To Enhance Ecological Assessments, Donald J. Benkendorf

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The temperature of streams and rivers is changing rapidly in response to a variety of human activities. This rapid change is concerning because the abundances and distributions of many aquatic species in streams and rivers are strongly associated with temperature. Linking observations of temperature effects on species distributions with observations of temperature effects on fitness is important for improving confidence that temperature (and not some other variable) is causing the distributions we observe. Furthermore, producing accurate models of temperature effects on species distributions may allow us to develop tools to diagnose whether or not thermal pollution has impaired aquatic life. …

The Influence Of A Course On Assessment For Inservice Secondary Mathematics Teachers, Natalie M. Anderson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There are relatively few opportunities for mathematics teachers to improve their assessment literacy. The purpose of this study is to (1) design a course on assessment for inservice mathematics teachers and (2) evaluate the effectiveness of the course. This paper recounts the development of the course and its influence on 16 teachers. Teachers who completed the course submitted a unit outline with learning objectives, a test blueprint, and a unit test. These artifacts influenced my evaluation on the effectiveness of the course. All …

Implicit Cost Of Retaliatory Tariffs By Mexico On U.S. Cheese Export, Pengyan Sun

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mexico imposed retaliatory tariffs on U.S. cheeses ranging from 20 to 25 percent in July 2018. In order to provide valuable information for the government and farmers, my research estimated the implicit cost of retaliatory tariffs by Mexico on U.S. cheese exports. In particular, I estimate the difference between the forecasted value of cheese exported to Mexico and the actual value of cheese exported to Mexico using four different models. The total impact to the U.S. economy from the losses due to retaliatory tariffs was assessed by IMPLAN, an input/output model. The results showed that Mexican tariffs decreased U.S. industry …

Regional Economic Contribution Of Crop Insurance Indemnity Payment In The U.S., Hwangwon Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Federal Crop Insurance Program (FCIP) has played a pivotal role in agricultural businesses and communities. The FCIP allows farmers to purchase farm and farm-related products and services, maintain heavy agricultural machinery, and utilize farm agency services for preparing for farming in the following agricultural years. In addition, the indemnities enable farmers to repay debts, alleviate farm collapses, and keep farm industries purchasing agricultural-related products and the necessary goods for everyday living, stabilizing the local and farming economies (Lubben & Thompson, 2013).

This study investigates the economic contribution of crop indemnity payments using a methodology that will capture the total …

Fitting Physical Models To Spatiotemporal Observations: Discovering Developmental Regulatory Networks Of Drosophila, Dj Holt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Deep learning continues to solve significant scientific and engineering problems, but the solutions found are neural networks with thousands of parameters that provide no scientific or engineering insights. A solution to this problem, explored in this work, is to learn mathematical models that represent mechanisms that can be interpreted by scientists and engineers.

A challenging learning problem is to discover the genetic regulatory mechanisms that drive pattern formation during early biological development. Using known mathematical models of these processes, consisting of coupled ordinary differential and partial differential equations, we aim to identify the model parameters that describe the biological mechanisms …

Exploring The Effects Of Upstream Disturbances On Elbow Meter Performance With Numerical Modeling Applications, Riley D. Manwaring

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Physical data was collected for a 6-in. long-radius elbow meter in order to determine the effects of certain upstream disturbances on its metering performance. Discharge coefficients are calculated for each of the three tested configurations at various installation distances between the upstream disturbance and the elbow meter. Computational Fluid Dynamics (CFD) software was used to determine which turbulence models most accurately modeled the observed physical results in order to provide a base from which to model the effects of additional upstream disturbances not modeled in this study.

Optimal Relative Path Planning For Constrained Stochastic Space Systems, Nathan Bohus Stastny

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Rendezvous and proximity operations for automated spacecraft systems requires advanced path planning techniques that are capable of generating optimal paths. Real-world constraints, such as sensor noise and actuator errors, complicate the planning process. Operations also require flight safety considerations in order to prevent the spacecraft from potentially colliding with the associated companion spacecraft. This work proposes a new, ground-based trajectory planning approach that seeks an optimal trajectory while meeting all mission constraints and accounting for vehicle performance and safety requirements. This approach uses a closed-loop linear covariance simulation of the relative trajectory coupled with a genetic algorithm to determine fuel …

Development Of A Machine Learning-Based Financial Risk Control System, Zhigang Hu

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

With the gradual end of the COVID-19 outbreak and the gradual recovery of the economy, more and more individuals and businesses are in need of loans. This demand brings business opportunities to various financial institutions, but also brings new risks. The traditional loan application review is mostly manual and relies on the business experience of the auditor, which has the disadvantages of not being able to process large quantities and being inefficient. Since the traditional audit processing method is no longer suitable some other method of reducing the rate of non-performing loans and detecting fraud in applications is urgently needed …

Measuring Srl Differences During Mathematics With Srl Microanalysis, Aliya Halterman

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Self-regulated learning (SRL) is an essential skill for achievement and progress in several settings including academics. It is known that students with attention-deficit/hyperactivity disorder (ADHD) struggle with SRL skills. However, this knowledge has been acquired primarily from self-report measures. While this has provided a solid foundation within the literature regarding SRL skills within the population with ADHD, there are a few limitations that these measures posit. These limitations can addressed with a measurement called SRL microanalysis. The purpose of this study was to use SRL microanalysis to measure SRL differences between students with and without ADHD symptomatology during a mathematics …

Let Us Live To Make Men Free: Locke And Aquinas On Toleration And Natural Law, Micah Safsten

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tolerance is a difficult and controversial concept in political rhetoric. For many, tolerance requires the acceptance of what one believes is evil. Still, most of us feel as though we must accept the differences of others on some level. This thesis is an attempt to better understand tolerance. To do so, it uses the concept of natural law, or the idea that all law should justified through one, universal theory of good. This would seem contradictory, as natural law supposes that a single vision of the good life exists for all. Yet the natural law theory of one legal theorist, …

Early Sibling Play Interactions As A Source Of Developmental Support For Toddlers: Observation Of Young Children's Developmental Support During Play With Toddler Siblings, Tasha L. Olson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The sibling relationship is a unique and important context for infant and early child development. Despite the important role of siblings and the unique aspects of the sibling relationship, sibling interactions are largely overlooked by scholars as a resource of potential developmental support. Identifying and fostering developmentally supportive interaction (DSI) behaviors in sibling relationships may expand available supports for children’s early development and may also support family well-being.

This study used a sample of 15 child-toddler sibling pairs to identify DSI behaviors in interactions between young children and their toddler-aged siblings, determine if and how well DSI behaviors could be …

Maternal Education And Changes In Parenting Beliefs, Values, And Practices, Becca E. Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Mothers’ education level has been an important predictor of life outcomes across many different areas. Higher education in mothers has been associated with outcomes such as higher reading levels and decreased chances grade repetition for their child. Due to gaps in the research, this study emphasizes the importance of mothers’ beliefs about parenting, the practices they use, the amount of closeness they have with their child, and how they change when mothers return to school. This study used new mothers and their newborn children across time to understand whether mothers’ beliefs, practices, and values change when mothers return to school. …

Measuring Changes In Motivation In Response To An Online Repeated Reading Intervention With Self-Monitoring, David N. Longhurst

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Reading is a complex cognitive process that is integral to learning, achievement, and future life outcomes. Students with reading disabilities struggle to obtain information and develop specific interests. Unfortunately, many students in the United States do not meet expected reading benchmarks. Also due to the impact of the COVID-19 pandemic, has presented multiple challenges for student academic reading growth. Motivation beliefs, such as self-efficacy, interest, and goal-directed behavior, play an important role in students’ education and development. This study examined whether motivational constructs change throughout the course of an online repeated reading intervention with self-monitoring. Five elementary students were selected …

Evaluating Short Term Effects Of Opportunity Zone Designation, Sarah M. Bennett

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

The Tax Cuts and Jobs Act of 2017 included a substantial economic development effort known as Opportunity Zones. These Zones cover 12% of the census tracts in the United States and are estimated to cost $1.6 billion in lost capital gains tax revenue. Our paper seeks to find whether this program has had an impact four years after going into effect, using an econometric analysis on changes in housing prices.

Oaths And Evasion: Variable Honesty In Tax Evasion Games, Logan Krebs

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

Previous research has indicated that an ex-ante pledge of honesty reduces the likelihood that participants will lie during a lab experiment. We show that a bandwagon effect, occurring when participants know that others are acting dishonestly, can erode the positive effects of honesty oaths. Taxpayers do not make their reporting decisions in a vacuum. They have access to information concerning how others in the community are behaving and develop perceptions around this information. We add these realistic features to a tax evasion game involving an ex-ante honesty oath. Results indicate that social context can reduce the positive effects of honesty …

Visions Of Science: An Art Historical Exploration Of Medieval Scientific Manuscripts, Olivia Brock

Undergraduate Honors Capstone Projects

The late 16th century saw a new movement in the world of science to push scientific ideas and practice out of academia and into the hands of the layman. No longer were scholars the sole proprietors of science –everyday laborers, craftsman, and artists now had practical scientific principles at their fingertips that they could incorporate into their professions. This new spread of science was facilitated in several ways, including the publication of books incorporating detailed, explanatory images, new utilitarian instruments, and public lectures. Though science was disseminated through a variety of means, I have been particularly interested in the ways …

Using Experiments, 3d Scanning, And Computational Fluid Dynamics To Analyze Variance In Minor Loss Coefficients, Adam B. Pack

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As water moves through pipes, it loses energy. The energy losses are due to friction and the minor losses associated with various pipe fittings, which change the direction of flow. Pipe bends, or elbows, are a common pipe fitting and a significant source of energy loss in piping systems. This research was performed to better understand the variability of energy loss due to different pipe elbow designs and to investigate methods to replicate these losses using numerical simulations.

Eight pipe elbows, all 3-inch, 90-degree, schedule 40 PVC elbows that vary by radius of curvature and/or end connection type, were tested …

Yang-Mills Sources In Biconformal Double Field Theory, Davis W. Muhwezi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There is a robust and unifying approach to unraveling the roiling mysteries of the universe. Our most compelling accounts of physical reality at present rest on symmetry arguments that are conspicuously geometrical!

105 years ago, Albert Einstein derived gravity from Riemannian geometry. In the general theory of relativity, the world of our experience is a pseudo-Riemannian manifold whose curvature represents the gravitational field. Encoded in the Einstein field equation is how matter sources (energy-momentum tensor) couple to gravity (spacetime curvature). Schematically, the Einstein equation exhibits a more general structure:

Curvature of Spacetime = Material Sources

On one side of the …

Quantifying The Indirect Effect Of Wolves On Aspen In Northern Yellowstone National Park: Evidence For A Trophic Cascade?, Elaine M. Brice

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Yellowstone National Park is renowned for its incredible wildlife, and perhaps the most famous of these species is the gray wolf, which was reintroduced to the Park in the mid-1990s. After reintroduction, it was highly publicized by scientists, journalists, and environmentalists that the wolf both decreased elk density and changed elk behavior in a way that reduced elk effects on plants, a process known as a “trophic cascade.” Aspen, which is eaten by elk in winter, is one species at the forefront of Yellowstone trophic cascade research because it has been in decline across the Park for over a century. …

History Strikes Back! The Portrayal Of Greek And Roman History In Hollywood Films And How It Furthers The Discussion Of History, Ethan P. Frost

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In an article published in 2009, Robert Rosenstone expressed disappointment in two films he played a role in developing the Reds (1981) and the The Good Fight (1984). He expressed regret the films did not reach his expectations as a historian. As a result, he wondered whether there was a point in historians being involved in the making of historical films.

This thesis focused on six historical films set in ancient Greece and Rome. The six films are Alexander the Great (1956), The 300 Spartans (1962), and 300 (2006) for Greek history; and The Last Days of Pompeii (1935), The …

Improved Digital Image Correlation Techniques At High Speed And High Temperature, Lindsey J. Rowley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In extreme environments, such as hot-fire rocket testing, gathering strain data can be challenging due to temperature constraints. Traditional methods for measuring material deformation such as strain gages, a small device attached to a test specimen, cannot withstand the extreme temperature and tend to burn off. When these situations occur non-contacting methods such as Digital Image Correlation (DIC) are preferable. DIC is an optical method of measuring strains across the material’s entire surface by using a camera to track the deformation of a speckle pattern applied to the surface of a deforming object. When used at temperatures above approximately 500°C, …

Designing And Decoding Chemical Bonds: A Computational Pipeline Backed Up By Magnetic Criteria And Experiment, Nikita Fedik

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

You may find plenty of definitions of chemistry but all of them, explicitly or not, are centered around chemical bonds. When we say “chemical properties”, “reactivity”, “stability”, “structure” etc., we have in mind chemical bonds and their reorganization which almost completely defines the behavior of the matter. Why some materials are ultrahard and can cut through steel while others are so soft that you can form them with your bare hands? You probably have already guessed that it occurs because their chemical bonding is very different. Although the elemental composition could be the same! In this Dissertation, we report results …
