“Gang, We Have A Mystery On Our Hands!”: A Folkloristic Approach To Conspiracy Thinking In Scooby-Doo! Mystery Incorporated, Sydney K. Brooks

All Graduate Reports and Creative Projects, Fall 2023 to Present

In this thesis I examined how the 2010 children’s television show Scooby-Doo! Mystery Incorporated both utilizes and critiques conspiracy, embedded within its mystery-solving structure. Through a close analysis of the members of the gang—Fred, Daphne, Velma, Shaggy, and Scooby-Doo—I broke down their individual behaviors, interactions, and contributions to conspiratorial belief. I then transitioned into a case study of the episode “Where Stalks the Scarebear,” showcasing its connection to larger real-world conspiracy narratives, particularly those related to corporate and environmental cover-ups. Finally, I examined the show as a complete narrative, reflecting on its complex, serial exploration of conspiracy through the framework …

"Death Is The Fifth [Season], And Master Of All": Necropolitical Violence And/As Environmental Violence In The Fifth Season, Mason T. Goodrich

All Graduate Reports and Creative Projects, Fall 2023 to Present

While many scholars have already described N.K. Jemisin’s Hugo Award-winning speculative novel The Fifth Season as one that highlights intersections between race, settler-colonialism, neoliberalism, and, most frequently, climate change, I apply a necropolitical lens to The Fifth Season in order evaluate a relationship that exists between systemic violence and environmental degradation. The Fifth Season depicts a socially inscribed relationship between an othered race of humans, called orogenes, and the land, anthropomorphized as “Father” Earth. Orogenes have a paradoxical social status: they are simultaneously feared and revered for their ability to control the Earth. This paradox is the impetus for many …

“Floptok Is Not A Trend. It’S A Lifestyle”: Camp, Performativity, And Community Dynamics In An Adolescent Tiktok Subculture, Drake Hansen

All Graduate Reports and Creative Projects, Fall 2023 to Present

Floptok is an online meme-sharing community or subculture that began to take shape in 2021, united by a particular sensibility and set of memetic materials. To outsiders, Floptok is seen as a loud, brash, and often abrasive community whose memes, characterized by low-quality audio and video, often feature “icons”—a range of invented characters and real people—and audio of pop songs heavily edited to feature hypersexual lyrics from the rapper CupcakKe, as well as portions of the 2019 Chinese pop song “Yěhuāxiāng.” This thesis built on scholarship in digital and young people’s folklore in an ethnographic case study of Floptok’s humor …

Climate Prediction As An Adaptive Force-Multiplier: Reasons For Hope In A Rapidly Changing World, Matthew D. Laplante

All Graduate Theses and Dissertations, Fall 2023 to Present

It's not unreasonable to feel pessimistic about our future under climate change. But "believing the science" doesn't require you to accept that we are headed toward apocalypse. It is true that human-caused climate change is real, it is underway, and our societies face many increased risks because of it. But that's just part of what climate science tells us about our future world. This same field is responsible for the recent and rapid development of tools and techniques that permit the identification of patterns in our oceans and atmosphere that will aid us in making increasingly accurate predictions about climate—the …

High-Throughput Phenotyping Of Early Generation Small Grains Breeding Lines To Indirectly Select For Grain Yield, Dalton Jones

All Graduate Theses and Dissertations, Fall 2023 to Present

In small grains breeding programs, breeders aim to develop better varieties by selecting for important traits like grain yield. However, it takes many years before yield can be measured because several generations of selection are required to fix lines and increase sufficient seed for yield measurements. This process can be slow and expensive

High-throughput phenotyping (HTP) is a modern approach that can increase breeding efficiency by leveraging technology to quickly measure secondary traits which can be used to indirectly select for important traits in crop plants. For example, researchers can use cameras on unmanned aerial vehicles (UAVs, i.e., drones) to …

A Model Of Changeover Behavior In Concurrent Schedules Of Reinforcement, Matias A. Avellaneda

All Graduate Theses and Dissertations, Fall 2023 to Present

Animals in the wild have access to a variety of food sources, and they must allocate their time between them in an efficient manner. This requires deciding when to depart from the source currently being exploited to travel to a different one. A general model of this decision process can be derived from three assumptions well supported by the learning literature. The first one is the so-called matching law, which says that the proportion of time allocated to any one behavior equals the proportion of total value obtained from that option. The second one is that the dwell times (i.e., …

Analyzing Microalgae-Bacteria Population Changes In Response To Environmental Parameters For Improved Wastewater Treatment, Amanda M. Moravek

All Graduate Theses and Dissertations, Fall 2023 to Present

Microalgae are incredible organisms that have a variety of uses such as wastewater treatment, fertilizer, livestock feed, and bio-compound production. Microalgae require a light source and minimal nutrients space to proliferate, making them an environmentally friendly and sustainable option for such processes. The Sustainable Wastes-to-Bioproducts Engineering Center at Utah State University is developing and implementing a Rotating Algae Biofilm Reactor (RABR) to remove total nitrogen and phosphorous from the Central Valley Wastewater Reclamation Facility wastewater effluent. Harmful compounds such as nitrates and phosphates are metabolized by the microalgae and converted into useful bioproducts, resulting in a circular economy. These RABRs …

Investigating Changes In Hydroclimate, Land Cover, And Evapotranspiration Across The Great Salt Lake Basin And Its Major Subbasins, Bhuwan Ghimire

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt Lake (GSL) is a lake of environmental and economic importance for Utah, and in recent years lake levels have declined to critically low levels. The lake level is dependent on the balance between the inflow and outflow. Inflow into the lake is governed primarily by the streamflow originating from the Bear, Weber and Jordan River basins (GSL subbasins), direct precipitation over the lake and groundwater entering into the lake. The GSL is a terminal lake, with outflow via evaporation from the lake.

In this study, we examined hydrologic processes within the river basins that relate to streamflow …

Seeding Rate, Planting Date, And Herbicides For Dormant Seeded Safflower In Utah, Rodney Daniel Nelson

All Graduate Theses and Dissertations, Fall 2023 to Present

Dryland crop production in the Intermountain West is largely limited by the amount of precipitation received. Increasing dryland safflower (Carthamus tinctorius L.) production yields in a semi-arid climate is possible with a dormant planting but is not well understood. A two-year (2020-22) project was designed to gain an understanding of the effects of variety, seeding rate, and planting date, on dormant seeded safflower. Chemical weed control options for safflower were also evaluated. One study, conducted at three Utah State University research farms near Blue Creek, Clarkston, and Kaysville, UT, evaluated four varieties, S-208, S-333, 7325 and Hybrid-446, seeded at …

Potamogeton Crispus Invasion: Impacts On Native Aquatic Plants And Associated Faunal Habitat, Meghan-Grace Slocombe

All Graduate Theses and Dissertations, Fall 2023 to Present

Aquatic invasive plants are non-native plants that invade a water body and displace native aquatic plants. Invasion depletes the native plant community's ability to provide ecosystem services, including improved water quality, decreased problematic algae, and increased animal habitat. The loss of these ecosystem services reduces the value of fishing, boating, and swimming opportunities in aquatic ecosystems. The potential changes in plant communities and services are particularly important at sites targeted for restoration because project goals typically include increasing ecosystem services, including wildlife habitat. Curly-leaf pondweed (Potamogeton crispus L.) is a problematic invasive species in North America. To better manage …

A Pavlovian, Conditioned-Reinforcement Approach To Reducing Impulsive Choice, Katherine Garland

All Graduate Theses and Dissertations, Fall 2023 to Present

Persistent impulsive choice (the preference for a smaller-sooner over a larger-later reward) is associated with consequential life outcomes. Procedures that reduce nonhuman impulsive choice have long training durations that may reduce their translational utility. The purpose of this experiment was to test a new behavioral intervention to reduce impulsivity that requires few sessions to implement. Delay-bridging stimuli (stimuli presented during the delay to a reward) have been shown to reduce impulsive choice, but delay-bridging stimuli may also be aversive. Conditioned stimuli (CS) established through Pavlovian training are, on the other hand, attractive, potentially even functioning as a conditioned reinforcer (CR). …

The Desert Shall Rejoice: Lds Relational Values And Multispecies Justice In The Intermountain West, Sarah A. Woodbury

All Graduate Theses and Dissertations, Fall 2023 to Present

In the American West, climate change is shifting weather and climate patterns in ways that may dramatically change lands, livelihoods, and communities. In the face of these threats, conservationists and local communities must work collaboratively to ensure that environmental and human communities are healthy enough to weather approaching shifts. Church of Jesus Christ of Latter-day Saint (LDS) values, practices, and histories strongly influence the Intermountain West, yet there is little research on LDS environmental values and perceptions. This study seeks to answer questions that work in this gap. It documents the knowledge and values of communities in the Intermountain West …

Seasonal And Temporal Influences On Successful Crossing Rates By Ungulates Of A North Utah Wildlife Overpass, Blake Ledbetter

All Graduate Theses and Dissertations, Fall 2023 to Present

Encroachment of human infrastructure fragments wild landscapes and introduces a suite of negative impacts for humans and wildlife. In Utah, roadways threaten migratory ungulates by creating a barrier to movements and preventing access to seasonal migration routes. To mitigate these conflicts, state transportation agencies often install wildlife crossing structures to allow animals to safely cross over or under roadways. Selecting the proper crossing structure requires consideration of the species of interest, landscape, location, and structural dimensions. Often there is balance between the optimal location, the dimensions of the crossing structures, and what is feasible given the landscape. In 2018, the …

Leadership, Identity, And Student Voice In Secondary Schools, Gordon S. Geddes

All Graduate Theses and Dissertations, Fall 2023 to Present

Many student leadership programs in U.S. high schools operate without clear guidance, often leaving students as passive participants in systems that may not effectively prepare them for leadership roles both in school settings and elsewhere. This study explores how listening to students’ voices can improve leadership programs by better understanding how young people see themselves as leaders. Using a case study approach at one school, I observed student leaders over one school year and analyzed their experiences through leadership development theories. The findings suggest that when schools take students' perspectives into account, they can create leadership programs that are more …

The Effect Of Dietary Protein Source On Gut Health, Spencer Lawson Schow

All Graduate Theses and Dissertations, Fall 2023 to Present

We investigated the impact of protein source in a western-style diet on colon cancer, colitis, and the gut microbiome. The Western dietary pattern is energy-dense, low in fiber, and has a sub-optimal micronutrient profile. Our group has formulated the Total Western Diet (TWD) that emulates the Western dietary pattern using survey data (NHANES), and we have demonstrated that this diet increases gut inflammation and colorectal cancer relative to a healthy control diet (AIN-93G), which is optimized for mouse health. However, the effect of protein source in the TWD and its effects on gut health have yet to be investigated.

Managing For Disturbance: Trade-Offs Associated With Population Resilience And Ecosystem Size, Ellie Wallace

All Graduate Theses and Dissertations, Fall 2023 to Present

Populations can recover from and withstand disturbance through characteristics such as reproduction and maintaining large abundances. While these traits are beneficial to native species conservation, they can simultaneously challenge effective invasive species management. Effective invasive species control requires sufficient efforts to overcome a population's ability to recover from disturbance, such as harvest. My dissertation aimed to address how the size of an invasive population and its ability to recover from disturbance impact a suite of invasive species control methods, including those that (1) target mainly larger and older individuals (i.e., mechanical removal), (2) target all sizes of individuals (i.e., targeted …

Uv-A Light And Heat-Activated Antimicrobial And Biodegradable Materials For Food Packaging And Preservation, Michael J. Bodily

All Graduate Theses and Dissertations, Fall 2023 to Present

Current food packaging materials are often non-biodegradable and harmful for ingestion, which poses a threat to the environment and public health. Thus far, the dangers of microbial contamination of food on human health have outweighed the risks associated with using these conventional packaging plastics. A possible solution to these issues is to use a combination of innovative materials and microbial inactivation methods that can potentially both reduce plastic waste and combat harmful microorganisms. In this study, two antimicrobial, biodegradable composites were developed and tested for their ability to inactivate two types of bacterium, Escherichia coli K12 and Listeria innocua, …

Greater Sage-Grouse Habitat Dynamics And Grazing, A Study Of Vegetation Indices And Survival, Codi R. Backen

All Graduate Theses and Dissertations, Fall 2023 to Present

North American rangelands are vast, open landscapes that support diverse ecosystems and provide many ecosystem services. Many wildlife call sagebrush rangelands home, including the Greater sage-grouse (sage-grouse; Centrocercus urophasianus). Sage-grouse habitat encompasses 165 million acres across western North America, and this bird has been of conservation concern as their populations drastically declined since the 1960s. Rangelands are also grazed by livestock, which has the potential to negatively affect sagebrush ecosystems when overgrazed or overstocked, which could be detrimental to sage-grouse nesting habitat. Additionally, sagebrush rangelands undergo annual variations in precipitation, temperature, growing season length, and vegetation vigor, which has …

Disentangling Factors Contributing To Population Performance Of Zion Bighorn Sheep, Ian Montgomery

All Graduate Theses and Dissertations, Fall 2023 to Present

Bighorn sheep populations across the western United States face increasing challenges from habitat loss, disease, and predation. In Zion National Park and surrounding areas, survey-based estimates indicate that the desert bighorn sheep population declined from over 800 individuals in 2018 to fewer than 500 in 2021. Understanding what drives these population changes is critical for effective wildlife management and conservation. This research examined key factors influencing population growth and individual survival to inform strategies for recovery in this bighorn population.

First, we analyzed which vital rates contributed most to population trends by estimating survival and reproduction rates from ground and …

The Impact Of Visually Presented Distractor Taboo Words During A Bilateral Attention Task, Chloe Taylor

All Graduate Theses and Dissertations, Fall 2023 to Present

Attention is a limited resource. Some events are able to capture one’s attention more efficiently than others, such as swear or sexual words. These events have preferential access to attentional resources and increase our arousal levels due to the activity of a neurotransmitter called norepinephrine. We investigate how well swear/sexual words capture peoples’ attention and interpret these effects in terms of norepinephrine activity.

Participants performed a visual task where they responded to different shapes presented while ignoring neutral or swear/sexual words presented on opposing sides of the computer screen.

Participants were significantly more inaccurate in identifying the shape present when …

On The Challenges Posed By Non-Machian Solutions To Relationalism In General Relativity, Zachary Matthew Zito

Undergraduate Honors Capstone Projects

The relationship between Mach’s Principle and solutions to Einstein’s field equations is examined, with special attention to Friedmann-Lematre-Robertson-Walker (FLRW) cosmology. Mach’s Principle is outlined, and the extent to which general relativity fulfills Machs vision is assessed. It is argued that several important solutions to Einsteins equations, particularly the FLRW cosmological models, embody key Machian features. In order to elucidate the FLRW cosmological model, the associated energy-momentum tensor for a perfect fluid under the assumptions of large-scale homogeneity and isotropy is derived and used to obtain the Friedmann equations that govern cosmic expansion. It is shown that FLRW cosmology can be …

Establishing Methods For In Vitro Static Culture Of Gut Microbiomes For Nutritional Intervention Studies, Jeremy Mathew Case

Undergraduate Honors Capstone Projects

Lipid oxidation products (LOPs), which form during high-heat processing of oils common in Western diets, are known to cause inflammation and cellular damage. While LOPs have been implicated in exacerbating colitis and promoting colon tumorigenesis in mouse models, their direct impact on the gut microbiome remains poorly understood. This capstone project aimed to develop a low-cost in vitro protocol to culture the mouse gut microbiome under anaerobic conditions, enabling future investigations into the direct effects of bioactive dietary compounds such as LOPs. The study also assessed whether viable microbial communities could be recovered from fecal samples stored at -80°C. Fecal …

Phylogeny And Historical Biogeography Of Uroleucon Aphids, Audrey Michelle Mullen

Undergraduate Honors Capstone Projects

The aphid genus Uroleucon (Aphididae: Aphidinae: Macrosiphini) is a diverse group of about 230 species found globally in most temperate regions, principally in the northern hemisphere. Only 23 species are described from the southern hemisphere, in South American temperate regions such as Chile, Argentina, and Peru. However, the origins of the South American species are unknown, as are the relationships of these taxa to northern hemisphere Uroleucon species. This study seeks to establish the relationships between Uroleucon aphids native to South America and their North American and Eurasian counterparts using genetic data. We use phylogenetic analysis of cytochrome c oxidase …

Adaptation Of Influenza A Virus Strains A/Anhui/1/2013 (H7n9) And A/Shanghai/1/2013 (H7n9) For Development Of Effective Mouse Models, Spencer T. Mullen

Undergraduate Honors Capstone Projects

The emergence of avian Influenza A (H7N9) virus strains in humans poses a significant threat to human health globally due to their pandemic potential, limited human immunity, and lack of virus-specific interventions. This capstone aims to address some of the limitations in antiviral research regarding Influenza A H7N9 virus by adapting two low-pathogenic virus strains A/Anhui/1/2013 (H7N9) and A/Shanghai/1/2013 (H7N9) to BALB/c mice through sequential passaging through lung tissue. Following 12 serial passages, increased virulence was observed as evidenced by increased virus replication, increased weight loss, and increased mortality in infected mice. Titration of the initial non-adapted virus isolates were …

The Impact Of Lactoferrin And Iron-Enriched Whey On Iron Absorption, Gastrointestinal Symptoms, And Menstrual Health In Women, Mia Dustin

Undergraduate Honors Capstone Projects

Iron is an essential trace mineral involved in oxygen transport, energy metabolism, and cellular function, yet deficiency remains prevalent among women of reproductive age. In the U.S., approximately 20% of women aged 18-45 years fail to meet daily iron requirements due to lack of iron consumption in the diet, menstrual blood loss, or intense exercise, often leading to anemia, fatigue, and cognitive impairment. While ferrous sulfate is a common form of iron supplementation, it frequently causes gastrointestinal discomfort. Researchers have explored lactoferrin, a glycoprotein with immune and iron-binding properties, as an adjunct to traditional supplementation. This study examines the effects …

The STAT2 gene encodes a protein called Signal Transducer and Activator of Transcription 2 and is an excellent target for genetic manipulation due to its essential role in type I and III interferon signaling pathways¹¹. A member of the STAT family of transcription factors, this protein is directly involved in mediating cellular responses to various cytokines and growth factors, particularly those related to the innate immune response¹¹. While the STAT2 signaling pathway …

Investigation Of Immune/Performance Trade-Offs In Neonate Children's Pythons (Antaresia Childreni), Ellie Hartman

Undergraduate Honors Capstone Projects

Energetic costs and constraints are key considerations when analyzing an organism’s life history and may require trade-offs to be made between different life history traits. One of these trade-offs occurs between investment in immunity and performance. The purpose of this study is to discover if this trade-off influences behavior in neonate Children’s pythons (Antaresia childreni). We hypothesize that snakes undergoing an immune response will have reduced behaviors promoting survival. To test this hypothesis, neonate Children’s pythons were randomly assigned to receive an immune challenge of keyhole limpet hemocyanin (KLH) or a vehicle injection as a control. Two days …

To Bee Or Not To Bee: Investigating Pesticide Behavior Inside And Outside Of Semi-Field Cages, Mallory Bingham

Undergraduate Honors Capstone Projects

Bees play an important role in ecosystems and food production through pollination. One such bee, the alfalfa leaf cutting bee (ALCB) is a very efficient pollinator and is essential in alfalfa seed production. However, bees face increasing harm, most notably due to the deleterious effect of pesticides used in agriculture, and much research is dedicated to investigating the extent of effects that pesticides have on different bee populations. One common tool used to study the effects of pesticide exposure on bees is semi-field cages. These cages have some key advantages, such as restricting bee foraging to plots sprayed with pesticides …
