All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this content analysis study was to identify the affordances embedded in core reading program (CRP) teacher’s manuals that facilitate graphical literacy skills as a component of literacy instruction. In the informational text selections of selected CRPs, graphic category, type, function, and connection to text were assessed to determine the kinds of graphics used to convey information. The instructional guidance associated with these graphics was then evaluated for type of instruction (no instruction, reference, and teach) and explicit instruction elements. The results from this study indicate that representation photographs and general images are the most prevalent type of …

Fingerprinting Paleo-Groundwater Sources Using Stable Oxygen And Iron Isotopes Of Iron Oxide Concretions From The "Boiler Room", Moab Area, Utah, Connor Frederickson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Isotopes are naturally occurring atoms of an element that vary in the number of neutrons present in their nuclei, resulting in different atomic masses. The most common stable isotopes of oxygen are oxygen-18 (¹⁸O) and oxygen-16 (¹⁶O). Geochemical processes, such as the formation of a solid mineral from dissolved elements in a fluid, can result in preferential concentration of one isotope over the other in a process known as fractionation. By measuring the ratio of ¹⁸O and ¹⁶O in solid minerals and using known fractionation values, the isotopic ratio of the fluid from which …

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, …

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 …

The Role Of Music Context In High School Students' Translations Among Representations In Algebra, Danielle Divis

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Previous research suggests that integrating music into mathematics can benefit students’ mathematics learning but leaves questions as to exactly how students interact with music context and mathematics simultaneously. This study used a descriptive multiple-case study design to understand the way high school students utilize music while engaging in music-contextualized algebra tasks. Eight pairs of high school students participated in this study. The procedures included training four volunteer high school teacher-researchers to carry out three music-contextualized mathematics lessons in their own classes. Data sources for each pair included three student work samples, three audio-video recordings of class sessions, and one audio …

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 …

Representation Of Students With Disabilities In Charter Schools Compared To Traditional Public Schools, Brenda K. Smith

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

There is a perception that charter schools enroll a disproportionately lower number of students with disabilities than traditional public school districts (TPS). Coupled with this perception are antidotal stories of students with disabilities being turned away by charter schools during the enrollment process. This study sought to determine what research has been completed to compare enrollment of students with disabilities in charter schools to enrollment in TPS, complete data comparisons on an entire state education system to see what enrollment differences exist for students with disabilities in charter schools and TPS, and review federal reports regarding students with disabilities to …

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. …

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 …

This thesis is an examination of the lives of Qassem Soleimani and Mustafa Kemal Ataturk through the lens of the political philosophies of Plato and Niccolò Machiavelli. Qassem Soleimani and Mustafa Kemal Ataturk were noted for their militant lives and share certain qualities of character in their pre-political careers that provide a unique opportunity for a direct comparison and the formulation of a normative claim assessing their relative successes and/or failures despite their many similarities. Through the course of this research the conclusion asserts that Mustafa Kemal Ataturk was a more capable man than Soleimani to ascend to a position …

On Predicting Omnidirectional Honey Bee Traffic Using Weather And Electromagnetic Radiation, Daniel G. Hornberger

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Honey bees are responsible for pollinating many important crops in the United States. However, honey bee populations have declined significantly since 1961. While some causes of this decline are known, others are not. By utilizing electronic bee hive monitoring (EBM) systems, bee keepers and researchers have an added resource in determining the causes of these declines so that the issues can be remedied. For nearly five months (May through October) during the 2020 honey bee foraging season in Logan, Utah, USA, we collected on-site weather and electromagnetic radiation (EMR) readings and videos of the hive entrances of six bee hives …

Numerical Cognition And Autism Spectrum Traits In Adults, Benjamin Covington

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Evidence suggests that individuals with high-functioning autism spectrum disorder (ASD) may be particularly inclined toward math proficiency, especially in adulthood. There is also evidence, however, that many of those with an ASD struggle in math as children compared to their typically-developing peers. These ostensibly inconsistent findings may indicate that individuals with an ASD struggle with number sense, a precursor to formal math, rather than with formal math per se. This account is compatible with evidence of a specific form of neural dysregulation, excitatory/inhibitory imbalance, in ASD that results in reduced signal-to-noise ratios (SNR) for processes that occur in downstream …

The research focuses on a development and investigation of utilizing a camera to simultaneously determine a drone’s state while locating landmarks, where there is uncertainty in the landmarks’ exact positions prior to the mission (SLAM). This SLAM method is performed in regions with limited access to GPS. Furthermore, there is development and investigation of controlling the drone in conjunction with SLAM using potential error-reducing control parameters. Objectives are to quantitatively understand the UAV’s sensitivity of position errors to sensor grade and …

Impacts In Fluids: Forces, Scaling Laws And Bouncing Modes In Projectile Impacts On Water Pools And Droplets, Rafsan Rabbi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Projectile impacts in quiescent water pool are synonymous with intriguing splash phenomena and rich underwater physics. Depending on the material property, geometry and surface conditions of the impacting projectiles coupled with the geometric properties of the water pool (e.g., depth, width etc.), contrasting events like sub-surface cavity formation or bouncing of macro-droplets unfolds over millimetric timescales.

In this dissertation, I present four different studies that look at different aspects of impact events with the help of high-speed imaging techniques and implementation of other sensory data acquisition instruments. Firstly, I look at the force of impact associated with projectile water entry …

Soil Health Monitoring And Management In Corn And Soybean Agroecosystems Of The Midwestern U.S., Bradley S. Crookston

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Soil health is a concept and condition of the soil where measurable soil properties represent the capacity of a soil fulfilling its intended use, such as producing crops, without constraint to its agro-ecological quality. Soil health assessments are used to estimate the health of a soil by assessing soil biological, chemical, and physical attributes, called soil health indicators, and scoring them on a scale, usually 0 to 100, to guide soil and crop management. However, there are few large-scale analyses of soil health assessment scores and their relationships with crop yield. Understanding how soil health assessments relate to crop yield …

Tractor Connections For Killing Tensors And Their Generalizations, Benjamin D. Shaw

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

We create new symbolic software tools for the analysis of Killing tensors. Central to our work is the construction of the tractor connection defined on the tractor bundle, which allows one to obtain information about the space of Killing tensors without solving the Killing equations–an approach termed the tractor approach. We give a new application of the tractor approach which allows one to more easily check explicitly for linear independence of a given set of Killing tensors. We develop software to implement such methods in the case of rank 2 Killing tensors; similarly, we develop software to implement analogous methods …

Geometrization Of Perfect Fluids, Scalar Fields, And (2+1)-Dimensional Electromagnetic Fields, Dionisios Sotirios Krongos

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Rainich equations provide a purely geometrical interpretation of matter in terms of the gravitational field it generates. All this takes place within the geometrical formulation of gravity provided by Einstein’s General Theory of Relativity. Rainich-type conditions giving spacetime "goemetrizations" are reviewed and extended. Three types of matter are considered: perfect fluids, scalar fields, and electromagnetic fields.

The Effects Of Explicitly Teaching Summarization Skills On The Reading Comprehension Of Students With Specific Learning Disabilities, Sherri Lay

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Students with reading disabilities struggle with comprehending what they are reading and the necessary strategies to help them understand what they read. Summarizing what was read is a proven strategy for improving reading comprehension. This project examined one strategy for writing summaries called Generating Interactions between Schemata and Text or GIST. Participants included two 7^th grade students and one 8^th grade student who were in Special Education classroom for reading services. The results of this study were inconclusive. Participants showed growth in their summarizing skills, but the growth could not be adequately attributed to the GIST strategy.

Characterizing Relational Values To Inform Message-Framing At The Boa Ogoi Historical Site, Cole G. Stocker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In an increasingly polarized political climate–particularly in the U.S.– environmental issues such as climate change and its effects on the environment have become hot-button partisan talking points resulting in further division. This has led to research on ways to communicate science which does not further inflame political tensions, but rather reinforces and validates the audience’s values. Science communication research provides the foundation for my case study, which focuses on characterizing the environmental values and worldviews of land managers residing and working near the Boa Ogoi Historical Site in southern Idaho. The Northwest Band of Shoshone Nation (NWBSN) is in the …

Then we focus on minimizing the running time of the overall procedure at query time utilizing precomputation and approximation. The city graph is partitioned into smaller groups of nodes and represented by its exemplar. In query time, source and destination pairs are connected to their respective exemplars and the path between those exemplars is found. After this, we move toward minimizing the city …

Predictive Models Of Post-Wildfire Debris Flow Volume And Grain Size Distribution In The Intermountain West, Sara Wall

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Post-fire debris flows represent the most erosive and potentially hazardous consequence associated with increasing wildfire severity. While an abundance of research has explored where they are likely to occur and their potential magnitude, investigations into understanding how they impact downstream resources are limited. Recent advancements are seeking to link predictive models together to be able to predict how erosion after wildfire may impact reservoirs and aquatic habitat downstream. However, there are two key missing pieces into our ability to examine watershed-scale impacts of post-fire erosion. These include having accurate predictions of how much sediment is likely to be deposited by …

Estimation Of High-Resolution Evapotranspiration In Heterogeneous Environments Using Drone-Based Remote Sensing, Ayman M. M. Nassar

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Evapotranspiration (ET) is a key element of hydrological cycle analysis, irrigation demand, and for better allocation of water resources in the ecosystem. For successful water resources management activities, precise estimate of ET is necessary. Although several attempts have been made to achieve that, variation in temporal and spatial scales constitutes a major challenge, particularly in heterogeneous canopy environments such as vineyards, orchards, and natural areas. The advent of remote sensing information from different platforms, particularly the small unmanned aerial systems (sUAS) technology with lightweight sensors allows users to capture high-resolution data faster than traditional methods, described …

Transformation Groups And The Method Of Darboux, Brandon P. Ashley

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the study of partial differential equations (PDE), one is often concerned as to whether or not explicit solutions can be obtained via various integration techniques. One such technique, known as the method of Darboux, has had particular success in solving nonlinear problems as demonstrated by the classical works of Goursat. Recently, Anderson, Fels, and Vassiliou provided a far-reaching generalization of Vessiot’s group-theoretic interpretation of the method of Darboux. This generalization allows for the characterization of Darboux integrable systems in terms of fundamental geometric invariants as well as the construction of Darboux integrable systems in general.

In this work, we …
