Discovering The True Meaning Of Federalist No. 27, Mckenzie Pedersen-Campbell

Undergraduate Honors Capstone Projects

The Federalist Papers are widely known as they helped explain the Constitution and gather support for its ratification. However, what they mean is not always clear. This is problematic, especially when Supreme Court Justices look to the Federalist Papers to help them make decisions. A particularly fascinating example of this problem arose in the case Printz v. United States (1997). Both the majority and dissent argued that their interpretation was supported by Federalist No. 27. That leads to the question of what Federalist No. 27 actually means. By looking at the context surrounding Alexander Hamilton (the author) and previous Supreme …

Reimagining Utah’S Block: Walkability As A Housing Shortage Solution, Jordan Taft Sheppard

Undergraduate Honors Capstone Projects

Utah, like much of the United States, is experiencing a housing crisis driven primarily by a shortage of available housing. Rising home prices, increasing infrastructure costs, and restrictive zoning policies have limited the supply of varied housing options, forcing many families into unsustainable housing and transportation patterns. While conventional development patterns have focused on outward expansion, this approach requires costly infrastructure investments and perpetuates car-dependent communities. This study explores an alternative solution—leveraging existing walkable urban land to accommodate growth more efficiently and sustainably.

Using a 15-minute city framework, this research identifies 2,528 acres of highly walkable land in Cache County, …

Door - To - Door Summer Sales And Other Summer Employment: A Cost And Benefit Analysis, Jentrie Gilliland

Undergraduate Honors Capstone Projects

Door-to-door summer sales is heavily marketed to college students, especially on university campuses in Utah. These employment options are marketed as having high financial rewards while giving students the opportunity to develop their professional skills. In this study, I examine whether these expected rewards are delivered and if door-to-door summer sales is a viable position for college students in comparison to other summer employment. Specifically, I focus on the financial benefits and skills gained from both job types as well as determinants for students who participate in door-to-door summer sales versus other summer employment. My findings indicate that there is …

Women’S Evolving Roles: Gender, Authority, And The History Of Latter-Day Saint Patriarchy, Zachary Brady

Undergraduate Honors Capstone Projects

This project aims to further understand contemporary women’s issues within the Church of Jesus Christ of Latter-day Saints by answering three questions. 1) What social and doctrinal factors have influenced the development of patriarchal structures within the LDS Church, and how have these factors evolved? 2) What are the current leadership and decision-making roles available to LDS women, and how does church membership feel about them? 3) What ideas exist for progress in gender equality and women’s leadership? This discussion provides relevant historical context, outlines current issues regarding LDS women’s authority challenges and theological interpretations, and numerous proposed solutions from …

Impacts Of Reef Fish Length On Foraging Radius: Exploring Behavioral Patterns Within A Patch Reef Ecosystem, Kilia Brawand

Undergraduate Honors Capstone Projects

Reef fish exhibit various behaviors upon the Great Barrier Reef. One of these behaviors includes that of limiting their grazing distances from a patch reef refuge to a certain maximum distance in order to avoid predators. This is defined as a ‘foraging radius’ or ‘margin of safety’. This ‘foraging radius’ varies among fish due to many factors- including species, morphology, ontogenesis, habitat complexity, and importantly: speed. Quicker fish can outswim predators to safety more efficiently than slower fish, and can therefore afford to travel farther distances to forage. Speed varies among fish for a number of reasons, including fish size …

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 …

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 …

Reevaluating The Drumian Carbon Isotope Excursion (Dice) In Western-Central Utah, Michelle M. Norman

Undergraduate Honors Capstone Projects

The Drumian Stage of the Cambrian Period is defined by the First Appearance Datum (FAD) of the cosmopolitan trilobite Ptychagnostus atavus in 504.5 Ma strata deposited on the slope and shelf of the Laurentia margin. The Drumian Global Stratotype Section and Point (GSSP), showing the best preserved example of P. atavus compared to global outcrops, is defined in the Drum Mountains of west-central Utah. Due to the inconsistent nature of fossil preservation, researchers have sought secondary proxies to identify Drumian-aged strata in the absence of age-diagnostic fauna. One key proxy is the Drumian Carbon Isotope Excursion (DICE), an ~-2.5‰ carbon …

Training Lander For Rover Arm Testing, James Peck

Undergraduate Honors Capstone Projects

The purpose of this honors capstone project is to design and fabricate a training lander to support the Utah State University (USU) rover team in preparation for the University Rover Challenge (URC). The URC is an international collegiate competition featuring four missions, one of which—the Equipment Servicing Mission—demands a high level of robotic arm functionality and operator skill. Historically, USU's rover teams have struggled to qualify for the URC finals, in part due to limited hands-on training opportunities with the robotic arm.

To address this gap, the training lander replicates the tasks found in the URC Equipment Servicing Mission, such …

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 …

State Legislature Demographics And Anti-Transgender Legislation, Sophie Christensen

Undergraduate Honors Capstone Projects

Starting in 2015, anti-transgender bills have been introduced in state legislatures in exponentially increasing numbers, with a sharp uptick in 2020 and numbers that nearly doubled every year since then. These bills concern a wide variety of issues, from sports participation for transgender adolescents to drag bans to restrictions on bathroom usage. This paper finds that only a small percentage of the bills are passed into law, indicating that passing laws is less important to legislators than introducing bills. Given these intentions, this paper seeks to analyze the demographic makeup of chambers that introduce and pass these bills to understand …

This research project focuses on women in accounting, especially mothers, and what changes can be made so that they are more likely to continue pursuing career growth, instead of becoming stay-at-home moms. This report focuses on what barriers women in Utah’s accounting profession face when trying to get promotions while fulfilling family commitments and how their perspectives differ from those of their management.

The basis of this research was done through a survey that …

Data Science For Engineers, Heidi Moulton

Undergraduate Honors Capstone Projects

Undergraduate research is a core pillar of Utah State University’s College of Engineering. Many students become involved with research during their Junior and Senior years and begin to generate various forms of data. Most students, however, have received little formal education on how to process data, and there are currently no readily available resources within the College of Engineering. As a Mechanical Engineering and Data Science double major, I found the data processing techniques I learned in my Data Science courses invaluable as an undergraduate researcher, and now as a Mechanical Engineer at Apogee Instruments, I frequently draw upon these …

Evaluating The Self-Healing Capabilities Of Engineered Cementitious Composite Mixtures, Emma W. Baggett

Undergraduate Honors Capstone Projects

Engineered cementitious composites (ECC) is a class of ductile fiber-reinforced concrete designed to exhibit strain-hardening and multiple fine microcracking, instead of large brittle cracks, under tensile loading. The presence of high volume of non-hydrated cement particles in ECC have demonstrated self-healing potential of cracks in ECC. This study evaluates the influence of two ECC additives, limestone powder and crumb rubber, on the self-healing performance of ECC. Three ECC mixture designs were developed: a control mixture, a limestone powder-modified mixture and a crumb rubber modified mixture. Self-healing was monitored over a period of 90 days under alternating wet and dry conditions …

Death In A Small Town, Christine Cooper

Undergraduate Honors Capstone Projects

Today, those who experience the loss of a loved one are far removed from the process of nursing the dying and watching over the dead. These tasks are relegated to professionals with specific education, certifications, and licensing. With advances in medical technology and hospitals in most communities staffed with well-trained doctors and nurses, the process of dying is more prolonged than that of the late-19th and early-20th centuries in rural small towns. Additionally, with the rise of the death care industry family involvement is often limited to choosing a casket and organizing services. In some ways death has become an …

Adversarial Voltage Transients In Multi-Tenant Fpga Environments, Andrew J. Gerber

All Graduate Theses and Dissertations, Fall 2023 to Present

A Field Programmable Gate Array (FPGA) is a special type of computer chip that can be reconfigured to implement a nearly unlimited number of functions. Recent trends have led some companies to offer cloud-based FPGA solutions. Researchers are exploring how to properly secure multi-tenant environments where the designs from two or more customers are placed on the same FPGA with logical and spatial isolation, though multi-tenancy is not yet commercially available in cloud FPGAs. The digital circuits within an FPGA require a clock to synchronize timing within the design. The maximum speed that this clock can run at is determined …

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 …

Development Of The Sexual Mindfulness Measure For Abstinent Persons, Kaitlyn Zito

All Graduate Theses and Dissertations, Fall 2023 to Present

Sexual wellbeing plays a crucial role in overall health, influencing physical, emotional, social, and even spiritual aspects of life. One key factor in sexual wellbeing is sexual mindfulness, or the ability to be aware and accepting of one's sexual thoughts, feelings, and sensations. While previous research has focused on sexual mindfulness in romantic relationships, little is known about how it applies to abstinent individuals. To address this gap, I developed a 16-item validated measure of sexual mindfulness specifically for abstinent individuals: the Sexual Mindfulness Measure for Abstinent Persons (SMM-AP). This tool adapts key elements from the Five Facets of Mindfulness …

Optimizing Nutrient Recycling To Achieve Zero–Discharge Management For Controlled Environment Agriculture, Noah James Langenfeld

All Graduate Theses and Dissertations, Fall 2023 to Present

Controlled environment agriculture (CEA) allows for human control of one or more environmental factors affecting crop production. Optimizing nutrient management in such systems allows for translation and predictions of sustainable management strategies in the field. These systems will be used to supply fresh food as public and private space agencies are planning to send humans to the Moon and Mars in the near future. Food resupply becomes increasingly difficult as the distance from Earth increases. Plants can be grown off-Earth as a food source, but their growth must be carefully managed to ensure long-term sustainability. I describe a model used …

Mighty Mycorrhizae, Continuum, and Myco Apply supported faster germination, while seeds treated with Spectrum and Seaweed took …

A Laboratory Study Of Local Scour And Driftwood Effects At A Type A Piano Key Weir, Manisha Panthi

All Graduate Theses and Dissertations, Fall 2023 to Present

Piano key weirs are a unique weir designed to increase the amount of flow that passes over it via its zig-zag shape (similar to the rectangular shape of keys of a piano). With its relatively small footprint, they are becoming more popular to upgrade existing water management projects and are also being used in new construction works. However, there is little information available regarding how these weirs handle sediment and driftwood. Additional information will help researchers and designers to understand the challenges of upstream sediment buildup, driftwood accumulation, and the effects of floods on downstream scour with viable protection measures. …

Development Of Saddlepoint Methodologies For Sparse Sample Multiple Parameter Generalized Linear Models And Correlated Data Scenarios, Christopher Johnson

All Graduate Theses and Dissertations, Fall 2023 to Present

Parameter estimation using maximum likelihood techniques may be biased when sample sizes are small, event rates are low, or otherwise sparse counts exist in a parametric model. This in turn may lead researchers to draw invalid statistical conclusions when conventional methods are utilized. The saddlepoint approximation has potential to lessen the degree of bias in sparse data conditions through its use of moments beyond the mean and variance, which allows for more accurate approximations using a smaller number of observations. We propose two novel saddlepoint methods for use in practical analysis scenarios, as an alternative to maximum likelihood estimation. First, …

Forging Resilient Futures: The Role Of Community Organizations In Addressing Environmental Injustices Faced By Immigrants Along The Wasatch Front, Utah, Nowrin Fatema

All Graduate Theses and Dissertations, Fall 2023 to Present

Utah’s Wasatch Front is an urban area with a growing population that faces looming environmental challenges, such as the desiccation of the Great Salt Lake, worsening air quality, water scarcity, and the impacts of urban sprawl. If not prevented, the lake’s desiccation or other environmental challenges could result in dangerous air pollution, biodiversity loss, and disruptions to local economies. Immigrant populations may be uniquely vulnerable to these environmental changes because of economic, social, and political marginalization. For example, 50% of Salt Lake City’s foreign-born residents live on the City’s westside—the area on the frontline of the lake’s toxic dust. My …

Gone With The Flow: Flow Reduction Coincides With Reduced Metabolism And Standing Stock Of Benthic Algae And Macroinvertebrates In Desert Rivers, Chloe E. Lyles

All Graduate Theses and Dissertations, Fall 2023 to Present

River metabolism, the measure of energy flow in a river, is driven by hydrological and physicochemical regimes (e.g., temperature, turbidity, and nutrients). However, these regimes are increasingly altered by human water demand and climate change-driven drought. These stressors alter the magnitude, timing, and duration of critical spring-snowmelt floods with poorly understood consequences on ecosystem function, particularly in desert rivers. To investigate the linkages between flow reduction, river metabolism, and basal food resource productivity (i.e., algae and aquatic invertebrates), we measured metabolism and basal resource availability in seven desert tributaries with varying degrees of flow reduction during low-flow conditions in 2023 …
