This approach supports sustainability by transforming waste into high-value products while minimizing environmental impact. However, scaling microalgae cultivation to industrial levels presents significant challenges, particularly in optimizing harvesting efficiency, reducing mixing and transport costs, and managing large water requirements.

This report compares the productivity, scalability, cost, and energy requirements of two primary cultivation systems: planktonic and biofilm. Planktonic systems, such as open raceway ponds (ORPs), excel in light distribution and nutrient uptake due to continuous mixing, …

Geometric Algebra For Field Theory In Curved Spacetime, Kevin Rhine

All Graduate Reports and Creative Projects, Fall 2023 to Present

Physics seeks to understand the universe by uncovering the fundamental laws that govern matter, energy, space, and time. At its heart lies the challenge of unification: finding a mathematical framework that consistently describes these interactions across all scales, from the subatomic to the cosmological.

This thesis explores geometric algebra, a mathematical language that unifies algebra and geometry, as a tool for advancing this understanding. By extending this framework to curved spacetimes, where gravity influences the structure of space and time, we investigate its ability to describe physical phenomena such as electromagnetism and general relativity. A notable contribution includes the geometric …

Aleci: An R Package For Non-Parametric Confidence Intervals On Accumulated Local Effects Plots, Matthew R. Lister

All Graduate Reports and Creative Projects, Fall 2023 to Present

Machine learning models can take a collection of inputs and craft an output. The mathematical formulas these models use to calculate their outputs easily become too complex or time consuming for a human to analyze. Collectively, we refer to these as black box models. Accumulated local effects plots (ALE) are a method for adding interpretability and visibility into the effects that individual variables contribute to the predictions made by black box models. The method designed by D.W. Apley calculates equally spaced point estimates of the response value to construct a graph across the range of the variable of interest. AleCI …

An Invitation To Language: Fostering Critical Language Awareness Through Assignment Design, Amrutha Smith

All Graduate Reports and Creative Projects, Fall 2023 to Present

First-year composition (FYC) instructors are often required to teach institution-issued course outcomes alongside their personal values. The author proposes a pedagogy to identify how teachers can invite rhetorical and linguistic agency in student writers and teach toward institutional objectives. To do so, the author shares her approach for revising existing and creating new FYC assignments that invite students to use their multiple codes and languagings (ways of communicating) in their writing. The assignments are driven by translanguaging approaches in writing instruction, specifically code-meshing and Critical Language Awareness (CLA), a theoretical framework coined by Shapiro, and integrate three settings in which …

However, I’ve been able to translate academic information in such a way that more people can understand it and learn from it. As people watch these academic videos, they will not only learn facts and terms about intercultural communication, but more importantly they will learn how to be more understanding people. They will learn to be …

How Does Fiscal Decentralization Shape Corruption?, Sharandy G. Appiah

All Graduate Reports and Creative Projects, Fall 2023 to Present

In this paper, I offer a comprehensive review of the impact of fiscal decentralization on corruption. Corruption has been a big hindrance to development, it undermines the inflow of foreign direct investment and even affects education. The literature on fiscal decentralization and corruption has conventionally argued that fiscal autonomy for local officials lowers corruption whereas most recent papers have found that fiscal decentralization increases corruption. I identify four possible pathways through which fiscal decentralization affects corruption and address possible reasons for the difference in findings in the literature. Understanding the mechanisms through which fiscal decentralization shapes corruption at the national …

Bomb Calorimeter As Proof Of Concept For Low-Cost Calorimeter To Measure Thermal Runaway In Pouch Cells To Facilitate Statistical Characterization, Mykell Johnson

All Graduate Reports and Creative Projects, Fall 2023 to Present

Transportation is becoming increasingly electrified, with the main energy storage system being lithium-ion (li-ion) batteries. Despite the widespread adoption of li-ion batteries, unique design abuse tolerance concerns need to be addressed, specifically regarding the catastrophic exothermic release of energy, called thermal runaway (TR). While TR is a major design consideration in all li-ion applications, it presents unique difficulties in the electric aviation industry. The Federal Aviation Administration (FAA) considers thermal runaway inevitable in a battery pack and requires containment of the event per DO311-A for certified aircraft. Due to the wide variability of TR, designing for this phenomenon can be …

"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 …

Gravity Wave Breaking Over Northern Utah With An Advanced Mesospheric Temperature Mapper And Sodium Lidar, Eric Davis

All Graduate Reports and Creative Projects, Fall 2023 to Present

Considerable progress has been made in recent decades in the understanding of gravity wave (GW) dynamics. However, there remain important aspects and effects that are poorly understood. In particular, the coupling and deposition of their energy and momentum into the mesosphere lower thermosphere (MLT) region and the interaction and instability dynamics that are directly associated with GW breaking. Using an Advanced Mesosphere Temperature Mapper (AMTM) several strong wave breaking events were observed in the summer of 2015 at USU’s BLO research station. These events have exhibited high momentum fluxes and associated strong wave breaking, prompting detailed data analyses. Rossby waves, …

“How Can I Make This Real Life?”: Realism, Politics, And Simulational Rhetoric In Video Games, Samuel Rowles

All Graduate Reports and Creative Projects, Fall 2023 to Present

Video games are becoming an increasingly relevant aspect of modern culture, both shaping discourse around topics of labor, play, and art, and being shaped by the society they are created within. Scholars have examined the link between video games and player behavior since the 1990s and found that there is little concrete proof that video games alter behavior on their own and are simply one part of a much larger context. But with video games increasing in complexity and accuracy, it becomes necessary to examine whether video games are capable of convincing players about truths of the real world through …

The Impact On Life-Cycle Consumption, Saving, Labor Supply, And On Bequests When Individuals Possess Time-Inconsistent Preferences, Barna Bose

All Graduate Reports and Creative Projects, Fall 2023 to Present

This study examines how the presence of time-inconsistent preferences affects a representative individual's decisions about how much to consume, to save, and how intensively to work, in addition to the size of a bequest to leave behind at death. The model is used to analyze the behavior of both time-inconsistent individuals (characterized by a hyperbolic discount function) and the behavior of time-consistent individuals (characterized by an exponential discount function). The model demonstrates how these two representative types of individuals make intertemporal choices over time. While the model distinguishes between time-inconsistent and time-consistent individuals with respect to using alternative discount functions, …

Increasing The Use Of Data-Based Individualization And Data-Based Decision-Making In Secondary Resource Settings, Melissa D. Garside

Tuning Out The Dark: Music As A Defense And Folk Solution, Melanie Kimball

All Graduate Reports and Creative Projects, Fall 2023 to Present

Music across cultures and throughout history is a tool for engaging with the supernatural. It shares similarities with apotropaic magic. Through research and ethnographic fieldwork, I argued that even in modern times, individuals use music as an apotropaic remedy for fear and negative emotions. These remedies reflect strategies identified by Jeannie Thomas, including companionship, magical substance, neutralization, and displacement. Modern apotropaic music regulates emotions, re-establishes personal relationships, creates safe environments, and provides a means of control.

Contributors used music to combat various negative feelings, selecting genres that matched their emotional needs. In the absence of family and friends, music reaffirmed …

Strategies For Increasing Methane Removal In Methanotroph Bench-Scale Systems For The Production Of Ectoine, Jaden Storrer

All Graduate Theses and Dissertations, Fall 2023 to Present

Anthropogenic methane emissions contribute to the greenhouse gas profile which is the chief cause of climate change. One significant source of methane emissions is biogas produced from bacteria in wastewater facilities and landfills. Methane rich biogas has the potential to be valorized into high value bioproducts by using methanotrophs (microbes that use methane as their primary carbon source). Methylotuvimicrobium alcaliphilum 20Z was selected for this study as it can generate ectoine when grown in highly saline environments. Ectoine has been proven to have many benefits such as it prevents protein denaturation, it has hydration properties, and is a UV protectant. …

All Graduate Theses and Dissertations, Fall 2023 to Present

This study explores how social media messages influence individual beliefs, attitudes and behaviors related to climate change. Despite widespread exposure to social media, there is concern about its effectiveness in shaping beliefs and actions regarding climate adaptation and mitigation. Research indicates that many people in the United States show limited concern for climate change, underscoring the need for targeted communication strategies. By designing and implementing a survey experiment with random participants within the United States, this study examines how sharing first- person experiences of climate-related hazards on social media affects opinions about climate change, in comparison to traditional third-person news …

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 …
