Righting Reproductive Wrongs: A Rhetorical Analysis Of Special Topoi In Alberto Fernández’S Pro-Voluntary Interruption Of Pregnancy Speeches, Kymberlie Crosby

All Graduate Theses and Dissertations, Fall 2023 to Present

The reproductive rights movement argues that abortion rights are fundamental and necessary for women to enjoy their human rights. Politicians opposed to abortion rights around the world have made it clear that they plan to ban abortion both statewide and nationwide. A country that has proven to be successful in defending its reproductive rights is Argentina. In 2020, the Voluntary Interruption of Pregnancy Bill (Interrupción Voluntaria del Embarazo; IVE) democratically passed and legalized abortion throughout Argentina. Argentine President, Alberto Fernández, supported IVE and delivered a series of speeches over four years highlighting IVE and the progress that has succeeded each …

Soil Additives And Alternative Crops For Drought Defense In The Intermountain West, Tina M. Sullivan

All Graduate Theses and Dissertations, Fall 2023 to Present

The Western U.S. looks for water optimization and conservation as agriculture is the largest water diverter, and resources are pressured by urban growth, winter snowpack instability, and drought persistence. Agricultural producers have several potential options to optimize water use with different investments associated with them. Options with varying levels of risks and known management practices include alternative crops, soil wetting agents, and crop biologicals.

An alternative crop that grew incredibly fast in popularity was industrial hemp (Cannabis sativa) despite limited agronomic knowledge for best management practices. Field trials occurred (2020-2022) near Logan, UT to test a total of …

All Graduate Theses and Dissertations, Fall 2023 to Present

Almost everything we interact with on a daily basis has been synthesized by chemists ranging from plastics, food preservatives, and medications. The diversity of synthetic molecules are achieved by the formation of new bonds between existing molecules and/or through the cleaving of bonds found in a molecule. There are uncountable amount of conditions reported to facilitate chemical reactions which all depend on the nature of molecules being used and the environment it is used in.

In recent years, more attention has been paid to identify chemical reactions that can use more environmentally favorable conditions and reduce the use of limited …

Dynamics Of Climate And Tectonics On Surface Processes And Their Sedimentary Archives In The Colorado Plateau And Basin And Range, Usa And The Calabrian Forearc, Sicily, Natalie M. Tanski

All Graduate Theses and Dissertations, Fall 2023 to Present

Landscapes change over time in response to movements of the Earth’s crust and the effects of climate. This dissertation examines how these factors shape different landscapes, focusing on erosion of river canyons in elevated plateaus, how the transport history in quartz sand may be encoded in its properties, and how a paleo-delta has formed in response to sea-level change and fault displacement. I use dating techniques, field methods, and topographic analyses to offer insight into erosional patterns and rates in different landscapes.

Rivers can take a long time to adjust to changes in boundary conditions, even after those changes have …

Silica Fault Mirror Development Along The Cordillera Blanca Detachment Fault, Peru, Kayla Michelle Chaudoir

All Graduate Theses and Dissertations, Fall 2023 to Present

Earthquakes occur along planes of geologic weakness called faults. Thin, light-reflective surfaces on faults are called fault mirrors and often considered signatures of previous earthquakes along these faults. The Cordillera Blanca mountain range in the Peruvian Andes provides a natural laboratory to explore meter scale exposures of fault mirrors. Three naturally formed fault mirror samples were collected from the Cordillera Blanca detachment fault which runs along the edge of the Cordillera Blanca mountain range. Prior work on this fault reveals that it is capable of destructive earthquakes every few thousand years and is a significant earthquake hazard to the surrounding …

Using Wasp Specimens In Taxonomic, Biogeographic, Evolution, And Informal Education Studies, Brenna Lynn Decker

All Graduate Theses and Dissertations, Fall 2023 to Present

Entomology collections hold an untapped wealth of information, from insect morphology, genetics, locality and association data, and potential for use in education. Especially with insects that generate initial fears, such as wasps, seeing insect specimens provides a safe environment to learn about their behaviors. Wasps are insects in the order Hymenoptera, along with ants and bees. The public may hold fears against wasps, due to their negative portrayal in various media, but they serve as integral components of a functional ecosystem. Even with their importance, many groups of wasps are still highly understudies. This dissertation aims to tackle this fear …

Hydrogen Stable Isotope Constraints On Hydration Of Colorado Plateau Lower Crust From Oligocene-Miocene Navajo Volcanic Field Xenoliths, Shelby Dianne Litton

All Graduate Theses and Dissertations, Fall 2023 to Present

Understanding flat-slab subduction is crucial as it involves the horizontal movement of an oceanic plate beneath a continental margin over a long distance. This tectonic process is widespread yet not fully understood, particularly regarding how it influences the chemical makeup of the continental plate and recycling in the hydrosphere. By analyzing isotopes, which are variations of certain elements found in minerals and water, we can gain insights into the sources of chemicals and geological processes at play. Our study area included six locations within the Navajo volcanic field (NVF), a region in the Colorado Plateau. We analyzed 23 lower crustal …

Informed Intervention Design, Deployment, And Analysis For The Computer Science Classroom, Jaxton J. Winder

All Graduate Theses and Dissertations, Fall 2023 to Present

Improving the teaching of computer science is a challenging task. Educators and computing education researchers devote large amounts of time, energy, and resources towards doing so effectively. One of the ways this is done is through research-informed design, deployment, and analysis of targeted interventions to the classroom. This thesis will detail research conducted at Utah State University targeting classroom interventions: centered around their design, deployment, and analysis.

One of these interventions aims to tackle student procrastination through the offering of “grace points”–forgiving a small amount of mistakes on a student’s assignment–for analyzing a homework assignment early. Through studying this intervention, …

To Pot Or Not To Pot: Understanding Technological Investment In Ceramics And Marine Mammal Oil Rendering In Kodiak, Alaska, Elizabeth Groat

All Graduate Theses and Dissertations, Fall 2023 to Present

Why do groups choose to use certain technologies, but not others? This study focuses on an especially confusing instance of this question: the adoption of pottery in Kodiak, Alaska. This event was strange for two reasons. First, by AD 1500, when Alutiiq ancestors in the Kodiak Archipelago began making pottery, their neighbors on the mainland had already been doing it for centuries—so why did they wait so long? Second, pottery is also only found in the south of the islands—so why did some people use it, but not others? Whale and seal are more abundant in southern Kodiak, so one …

The Drivers And Ecological Importance Of Streamflow Permanence For Native Salmonids: Evaluated At Multiple Spatio-Temporal Scales, Skylar Rousseau

All Graduate Theses and Dissertations, Fall 2023 to Present

In freshwater ecosystems, aquatic resources are distributed patchily across both space and time. Non-permanent streams, which go through periodic episodes of drying and rewetting, account for more than half of all streams in North America and help create much of the diversity that defines aquatic ecosystem form and function. While non-permanent streams have become increasingly common under climate change, we have a poor understanding of both their distribution across the landscape as well as how native stream fishes make use of them when they are flowing. I analyzed a large data set that spanned multiple decades across the northern Rocky …

Fishing Vessel Detection In Exclusive Economic Zones From Low Earth Orbit Satellites With Power And Computational Constraints, Kyler E. Nelson

All Graduate Theses and Dissertations, Fall 2023 to Present

Illegal fishing activities pose a significant threat to the sustainability of marine ecosystems and the economies and societies which rely on them. Detection of fishing vessels engaging in illegal activity is difficult, as many ships engaging in such activity actively avoid detection through radio systems used for maritime traffic monitoring. Satellite imagery provides a promising means for detecting fishing vessels, though designing an effective system is difficult due to limited availability of labeled image datasets of fishing vessels. This research proposes a system to detect illegal fishing activity through the use of a low-power ship detection satellite and proposes a …

Citizen Science Project On Urban Canids Provides Different Results From Camera Traps But Generates Interest And Revenue, Neville F. Taraporevala

All Graduate Theses and Dissertations, Fall 2023 to Present

As more people live in cities, wildlife increasingly encounters people. Coyotes (Canis latrans) and red foxes (Vulpes vulpes) are two carnivores that have easily adapted to urban environments causing them to come into conflict with people and their pets. Citizen science, where members of the community aid scientists in the collection of data, has emerged as a low-cost method of studying these species that can provide benefits to management agencies but may provide different results than traditional methods. We analyzed data collected by citizen scientists and data collected via motion-triggered camera traps to see how each …

Understanding Ion Rejection Mechanism Of Freeze Desalination By Molecular Dynamics Simulation, Mahbuba Jannat

All Graduate Theses and Dissertations, Fall 2023 to Present

This study explores a method called freeze desalination, which uses the natural process of ice formation to remove salt from water at lower than freezing temperature of water, which is 235K (Freezing temperature of this water model is 249K), making it safe for potable water. Unlike traditional methods, freeze desalination can be more efficient and environmentally friendly, but how it rejects salt at the molecular level is not very clear to understand. Using molecular dynamics simulation, this research aims to uncover the details of this process. We focused on understanding how water molecules interact with salt ions during freezing. Our …

Shifting Paradigms In Recreation Management: Applying Social-Ecological System Frameworks To Parks And Protected Areas, Noah Creany

All Graduate Theses and Dissertations, Fall 2023 to Present

Park and protected area (PPA) recreation management is often characterized by social, ecological, and managerial dimensions. These dimensions have increasingly been conceptualized as social-ecological systems (SESs) to understand the complex interrelationships between them. Contemporary trends of increased visitation on public lands in the United States, including US National Parks, have accentuated the complex interactions between the amount of recreation use, the capacity of the setting, the quality of the visitor experience, and ecological resource conditions. These challenges of managing recreation use and understanding these interactions will be further compounded by climate change and its effects on ecosystem composition and dynamics. …

All Graduate Theses and Dissertations, Fall 2023 to Present

This study examines student engagement during academic tasks, specifically investigating how the presence and type of observer affect student performance. The objective was to understand the influence of different observer conditions—no observer, an observer behind an observation window, a researcher in the session room, and a caregiver in the session room—on student behavior. Using a multi-element design, the study assessed three measures: active on-task behavior, passive on-task behavior, and academic work completion. The literature review identified a lack of recent research on how students respond to adult observers during academic tasks and highlighted the variability in definitions of engagement. To …

Invasion Potential Of Nonnative Fishes Through A Large Western Dam Into A Prized And Vulnerable Ecosystem, Barrett T. Friesen

All Graduate Theses and Dissertations, Fall 2023 to Present

Native river fish face threats from habitat fragmentation, water overallocation, invasive species establishment, and powerful synergies amongst these factors. In the Colorado River Basin, USA, these threats coalesce at Glen Canyon Dam (GCD), which impounds the Colorado River to create Lake Powell, a reservoir inhabited by nonnative fish species. There is widespread concern low water level in Lake Powell may allow nonnative fish to escape through the dam, adversely affecting native fish species downstream in the Grand Canyon. In this study we characterized the seasonal distribution of nonnative fishes in the vicinity of GCD and identified environmental conditions that may …

Evaluating Social Interactions As A Byproduct Of The Good Behavior Game Within An Elementary Small Group Classroom, Emma Walton

All Graduate Theses and Dissertations, Fall 2023 to Present

Children with Autism exhibit significantly fewer social interaction behaviors than their neurotypical peers. Much of the research around this deficit focuses on early intervention, and specialty services such as ABA intervention. The Good Behavior Game is an interdependent group contingency that has been shown to improve academic, social and appropriate behaviors in a variety of settings. This study explored the effects of the GBG on the social interactions of elementary students within special education without specifically targeting social interactions with peers through the game's rules. This study found negative (null) results, indicating that the GBG did not affect the social …

Trade-Offs In Lighting For Dic Strain Measurements In Vibration-Based Fatigue Testing, Jacob R. Rigby

All Graduate Theses and Dissertations, Fall 2023 to Present

Vibration based fatigue testing offers a fast and efficient method for determining the breaking point of a material. This method often uses a device, called a strain gage, to measure the deformation of a test sample at a single spot on the test sample. However, these strain gages often break before testing is complete. To overcome this premature break, a laser vibrometer is often used to measure the amount of movement or the speed of the test sample throughout the vibration test. The deformation measured by the strain gage is compared against the amount of movement or velocity of the …

This study evaluated if levels of change in mental health, conflict resolution, support, and companionship differed between sociodemographic groups who participated in a blended family relationship education program. Regarding individual mental health, females who were students improved more than non-students and those who had a bachelor’s or advanced degree improved more than those with a high school education or less. Male mental health across sociodemographic groups tended to be worse at posttest than baseline. Among couples, conflict improved more for those who were married and the female partner had a bachelor’s or advanced degree, were low income and female partners …

Comparative Morphology And Development Of The Trigeminally Innervated Infrared-Imaging System In Boas And Pythons, Helen Bond Plylar

All Graduate Theses and Dissertations, Fall 2023 to Present

Boas and pythons use specialized sense organs called pit organs to detect radiant heat. Pit organs in these lineages occur in paired arrays along the upper and lower jaws and are served by the trigeminal nerve (the fifth cranial nerve and one of the largest). Information from the pit organs travels via branches of the trigeminal to the brain and ultimately is processed in the optic tectum, along with information from the visual system. That means these snakes effectively “see” heat. While studies of the pitviper infrared-imaging system are numerous, very few studies of this system in pythons or boas …

Effect Of Nutrient And Temperature Conditions On The Production Of Microcystins From Cyanobacteria In Pineview Reservoir, Brent G. Jacobson

All Graduate Theses and Dissertations, Fall 2023 to Present

Cyanobacteria, sometimes known as harmful algae, are an aquatic bacteria capable of producing toxic compounds. Cyanobacteria are found worldwide in both saltwater and freshwater environments. Depending on the environment, toxic cyanobacteria species can outcompete other aquatic species, grow in large numbers, and produce these toxic compounds. Further understanding of what environmental conditions promote the production of these harmful bacteria and toxins is needed to protect and inform the public.

In order to understand why cyanobacteria produce toxins in certain environments, samples containing cyanobacteria were taken from a Pineview Reservoir, Utah, and cultured at the Utah State Water Research Laboratory. Cyanobacteria …

Rapid Prediction Of Buoyancy-Driven Exchange Flows At The Great Salt Lake: Ml Models And A 1d Shallow Water Approach, Eric M. Larsen

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt Lake in Utah, USA, is a hypersaline terminal lake divided in to northern and southern arms by the Union Pacific Railroad causeway since the 1950's. This separation has caused a difference in density and water surface elevation between lake arms. These differences result in a buoyancy-driven exchange flow occurring through an engineered breach in the causeway. Traditionally, modeling the flow through the breach has been done by numerically solving the 1D steady shallow water equations, and using computational fluid dynamics (CFD). The CFD models yield high accuracy results, but require substantial computing resources. This research proposes the …
