Online Deception: The Impact Of Language In Text-Based Deception Detection, Stephanie Dayle Avila

All Graduate Theses and Dissertations, Fall 2023 to Present

In today’s digital age, spreading false information online can have serious consequences, from affecting elections to undermining public health efforts. Despite the issue's importance, there’s been relatively little research into better understanding how people make decisions about lies and misinformation online. My project dives into this challenge by exploring how specific language cues, like grammar errors or unusual word choices, influence people’s perception of statements in terms of deceit online. I examined how people react to these cues through three separate but related studies when reading truthful and deceptive statements. The first two studies showed that true statements with grammatical …

On The Existence Of Periodic Traveling-Wave Solutions To Certain Systems Of Nonlinear, Dispersive Wave Equations, Jacob Daniels

All Graduate Theses and Dissertations, Fall 2023 to Present

A variety of physical phenomena can be modeled by systems of nonlinear, dispersive wave equations. Such examples include the propagation of a wave through a canal, deep ocean waves with small amplitude and long wavelength, and even the propagation of long-crested waves on the surface of lakes. An important task in the study of water wave equations is to determine whether a solution exists. This thesis aims to determine whether there exists solutions that both travel at a constant speed and are periodic for several systems of water wave equations. The work done in this thesis contributes to the subfields …

Top-Down Vs Bottom-Up Effects On Predator-Prey Interactions In Aquatic Communities, Catherine Mary Mcclure

All Graduate Theses and Dissertations, Fall 2023 to Present

Ecology is studied at multiple scales to better understand how small changes at the individual level scale up to affect our ecosystems and global systems. These ecological scales include individuals (single organism), populations (group of organisms of the same species), communities (populations of different species interacting with each other), and ecosystems (species interacting with other species and their local environment). The research in this document is focused on the individual, population, and community scale. In particular, this research addresses questions regarding how changes in environmental conditions (i.e., predation and resources) affect species interactions which ultimately affects the composition of ecological …

Sustainable Fertilizer Management Practices For Container Nursery Production, Saroj Burlakoti

All Graduate Theses and Dissertations, Fall 2023 to Present

Growing nursery plants in containers requires a timely supply of mineral nutrients for optimum growth. However, there is a misconception among growers that the application of higher doses of fertilizers hastens plant growth; instead, it can lead to runoff and leaching loss of nutrients. Reducing fertilizer application while sustaining healthy plants can not only negate environmental consequences but also save fertilizer costs. For example, two ground covers, Lysimachia nummularia (creeping jenny, moneywort) and Vinca minor 'Bowles' (periwinkle), can be grown for three months by applying 6 mg/L of phosphorus (P) as reduction of P to single application of 6 mg/L …

Quantifying The Role Of Karst Groundwater On Mountain River Discharge, Devon Hill

All Graduate Theses and Dissertations, Fall 2023 to Present

A primary objective of hydrological research is to anticipate the shifts in water supply due to climate change. These shifts are difficult to predict in karst areas like Logan Canyon because much of the water moves through large fractures and cave networks that transport groundwater quickly, but there are some groundwater fractions which move very slowly. Many studies in karst regions use spring dynamics to assess aquifer condition, but overlook other influences such as exchanges between a river and the underlying aquifer. In this study, we calculated the quantity and chemical makeup of these groundwater and surface water exchanges by …

Nutrient Management Of Cannabis In Controlled Environments, Julie A. Hershkowitz

All Graduate Theses and Dissertations, Fall 2023 to Present

Cannabis has been cultivated for millennia as a multipurpose crop for food, fiber, and medicine. Secondary metabolites called cannabinoids, including cannabidiol (CBD) and the psychoactive Δ-9 tetrahydrocannabinol (Δ-9 THC), are responsible for the medicinal properties of cannabis. The intoxicating nature of THC resulted in legislation prohibiting the possession and production of cannabis within the United States during the 20^th century. As a result, research programs on cannabis production were halted at most institutions. In recent years, cannabis production has become widespread within the US as a result of increasing legalization. However, modern cannabis production nutrient management programs often include …

Public Cyberattack Attribution And Domestic Political Considerations: An Analysis Of State Decision Making, Ella M. Devey

All Graduate Theses and Dissertations, Fall 2023 to Present

When a country is targeted with a cyberattack, what compels its government to publicly attribute the perpetrators of the attack rather than keep their attribution private? Cyberattacks are an increasingly utilized weapon of international conflict by governments, groups, and individuals. Following a cyberattack, the target of the attack may investigate the origin of the attack and may choose to share their findings with the public; alternatively, they may choose not to publicly share their findings.

While we know that forensic capabilities and international political factors contribute to the decision of governments to make public cyberattack attribution, domestic political circumstances may …

An Expansive Framing Intervention And Its Influence On Nursing Students' Perceptions Of Value For Mathematics, Kimberly Evagelatos Beck

All Graduate Theses and Dissertations, Fall 2023 to Present

Nurses regularly use mathematics on the job, yet they often do not view their work as mathematical. This may indicate a lack of transfer from the nursing school mathematics context to nursing practice. Further, nursing students often perceive very little usefulness and relevance for learning mathematics beyond simple calculations. Expansive Framing (EF) is a theory and instructional technique that has been shown to foster transfer by establishing intercontextuality, or connections made between disparate contexts. This research explored whether creating intercontextuality created through broad framing also improved perceptions of mathematics value and transferability, and how intercontextuality functioned as the driver of …

What Is Biological Engineering? – A Magazine, Morgan Christensen

Undergraduate Honors Capstone Projects

Biological Engineering is one of the less commonly known fields of engineering and can be challenging to describe to someone outside the discipline. The most common question I've been asked during my undergraduate career is "What is biological engineering?". My answer has changed throughout my time at Utah State University as I've had more experiences within the discipline.

Simulating Ice Particle Properties Under Varying Electric Fields, Joseph Thomas Cooney

Undergraduate Honors Capstone Projects

In this study, the interactions between atmospheric water molecules and an electrically charged dust particle were simulated in python to determine the role of electric charge and electric fields in atmospheric ice formation. Multiple levels of electric charge were tested, corresponding to different strengths of atmospheric electric fields. The TIP4P-2005 model for water was used to simulate these molecules under the influence of a central electric potential to represent the charged dust particle. These included a control group with no electric field (0 C), a group under a fair-weather strength of electric field (1.6*10-14 C), a foul-weather electric field (1.6*10-12 …

How Variation In Activity Time And Duration At Water Sources Affects Feral Horse Vulnerability To Cougar Predation In Southern Nevada, Katelyn Davies

Undergraduate Honors Capstone Projects

Feral horses have become prominent in the Intermountain West. Approximately 43,000 horses are found in Nevada alone. With increasing numbers, they have become a large portion of ungulate biomass. Thus, it is important to understand their behavior, as they become integrated into western wildlife communities. However, little research has been conducted on the ecology of feral horses, and their relationships with native ungulates, carnivores, and local resources such as water.

To address these concerns, I outlined three objectives: (1) determine if horses changed their water visitation activity times in relation to temperature. As a primarily diurnal species, we were interested …

Testing Resilience Of Microalgae Biofilms When Exposed To Hydrothermal Liquefaction Aqueous Phase, Davis Riley Haag

Undergraduate Honors Capstone Projects

There are a multitude of experimental and processing techniques in the bioenergy field that produce sustainable and carbon negative to carbon neutral methods of converting renewable resources into biologically based hydrocarbons. One example of a process is hydrothermal liquefaction (HTL) which specializes in converting wet biomass into biocrude oil. One reason that these processes are not used outside experimental testing is due to the high cost of performing these processes. There is potential to move these processes to larger scale testing and eventually industrial adaptation if breakthroughs are made to offset the process expenses. There is a waste product produced …

Priming Through Persuasion: Towards Secure Password Behavior, Rizu Paudel, Mahdi Nasrullah Al-Ameen

Computer Science Student Research

Users tend to create weak passwords even for the important accounts. The prior research shed light on user’s insecure password behavior, and why the interventions, including requirement specification (e.g., password composition policies) and feedback systems (e.g., password meters) fail in practice. To this end, we propose and evaluate the concept: priming-through-persuasion in the realm of secure password creation. In particular, we created visual designs, aimed at priming users about the repercussions of weak passwords before their password creation. We base our designs on two forms of persuasion methods: pathos and logos. Pathos appeals to people’s emotion in order to persuade …
