It follows my journey around Ireland, including Killarney, Dingle, Kell’s Bay, Castle Desmond, Galway, the Aran Islands and Coole Park. This essay is in communication with other travel writing pieces as I experiment with the genre. In preparation I read many different examples of travel writing including Travels with Charley, Stones of Aran, and On the Shoreline of Knowledge. My initial plan for this project involved studying cultural differences and experimenting with the genre of travel writing. While I began this project without a …

Connection And Isolation: A Musical Exploration Of Emotion, Kimberly Ann Lewin

Undergraduate Honors Capstone Projects

Music is emotional and inherently connective, and this paper addresses how research in social work and emotion can be communicated and understood using a musical performance. Using the research of Dr. Brené Brown, I explored the concept of "near" and "far enemies" of emotion with a musical perspective and commissioned composers to write a piece of their interpretation. "Near" and "far enemies" are Buddhist terms typically attributed to the Four Immeasurables: loving-kindness, compassion, empathetic joy, and equanimity. The far enemy of an emotion is its opposite, and it typically produces a harsh outcome. Near enemies are not as obvious. Similar …

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 …

Fostering Futures: Serving As The Collegiate Mentor For The Utah 4-H Stem And Agriscience Ambassadors, Cassandra G. Ivie

Undergraduate Honors Capstone Projects

Combining principles of community engagement, psychology, and computer science, this project was created to apply academic knowledge to a community based need. Whereas girls have been shown to be less likely to believe they had the necessary qualities to study STEM (Merayo & Ayuso, 2022), report having learned about fewer STEM concepts by the end of high school (Merayo & Ayuso, 2022) and indicate higher rates of avoidance due to feeling incapable (Gallup, 2023), girls involvement in STEM was a primary focus for the project. As rural students also see a drop in STEM interest, have less access to advanced …

Evaluating Taxonomic Approaches: A Comparative Study Of Educational Frameworks Applied To Mathematics Assessments, Lily Roth

The interviewees all had varying levels of experience in differing fields of expertise. I asked them a series of questions regarding their past and current experiences with theater. Regardless of their level of involvement or whether they were currently pursuing it, all of these participants agreed that theater …

Pedestrian Crossing Environmental Impact Statement, Alyssa Gaither

Undergraduate Honors Capstone Projects

Logan, Utah is divided by US Highway 89/91, which bisects much of the city. This makes it difficult to pass to the other side without a vehicle. A pedestrian crossing has been proposed to connect the eastern and western sides of Logan without impacting traffic flow. The Environmental Impact Statement aims to look at reasonable alternatives and identify many resources that will be affected by its implementation. Four main alternatives were considered: an underpass, an overpass with an elevator, an overpass with a ramp, and the no-change alternative to be used as a baseline alternative. The underpass is the preferred …

A Review And Critical Analysis Of Yoga And Mindfulness Meditation In Pain Management For Individuals With Rheumatoid Arthritis: Design Of Prospective Yoga Intervention Lesson Plans, Jamie Butikofer

Undergraduate Honors Capstone Projects

Rheumatoid Arthritis (RA) is a chronic autoimmune disease that causes joint pain, inflammation, and in some cases permanent damage. This research project explores yoga’s potential to manage pain and improve quality of life for RA patients. A review of existing research investigated the impact of yoga on pain and function in RA. Studies employed various yoga programs, making comparisons difficult. All studies reported improvements in areas of pain, inflammation, emotional and mental wellbeing, or disease activity. Interestingly, meditation, a core tenet of traditional yoga, emerged as a potentially beneficial component. Studies suggest it may help manage chronic pain and improve …

Impacts Of Lake Elevation Decline On Tui Chub, A Critical Forage Species For Lahontan Cutthroat Trout In Pyramid Lake, Nevada, Usa, Sarah Barnes

All Graduate Theses and Dissertations, Fall 2023 to Present

Lake level decline affects lakes worldwide, changing the availability and character of nearshore habitat used by fish to spawn, and increasing total dissolved solids (TDS), similar to salinity, a factor that negatively impacts fish health. Lake level decline can affect different lakes in different ways, but typically when lake level declines significantly, there is less nearshore habitat overall, and what nearshore habitat remains has less diverse habitat for fish. We investigated whether both impacts of lake level decline may be causing declines of Tui Chub Siphateles bicolor, a large minnow native to Pyramid Lake that spawns in nearshore habitat. …

Acoustic-Perceptual Relations Between Fundamental Frequency And Expressiveness In Speakers With Hypokinetic Dysarthria, Alena Portnova

All Graduate Theses and Dissertations, Fall 2023 to Present

Hypokinetic dysarthria is a motor speech disorder that occurs in patients with Parkinson’s disease (PD) and affects not only their speech intelligibility but also how their attitudes and emotions are perceived by listeners. People with PD have been judged as less happy, involved, friendly, and interested based only on their speech samples. A lack of speech expressiveness is one of the characteristics that is likely to be related to these negative listener judgments. Specifically, it has been suggested that a lack of fundamental frequency (F0) variation reduces speakers’ ability to express various emotions. To investigate whether speech expressiveness is related …

The Effects Of Ammonia On The Functionality Of Bovine Granulosa Cells, Micah Henrie

All Graduate Theses and Dissertations, Fall 2023 to Present

It is common practice in the livestock animal production industries to feed high levels of protein to maximize the yield of each animal in production. However, diets high in protein can cause decreased reproductive success within these animals. The causes behind this decrease are not fully understood. Increased dietary protein leads to increased levels of both ammonia and urea in the blood of the animal. These increased metabolite levels may be a possible explanation for the decline in reproductive success. The goal of this study is to identify how various levels of ammonia affect the function of bovine granulosa cells …

The Role Of Extracellular Vesicles In Immunomodulation During Bovine Pregnancy, Amber E. Thornton

All Graduate Theses and Dissertations, Fall 2023 to Present

During pregnancy, the maternal immune system must be altered to protect the partially non-self fetus from attack. Our previous studies show an inflammatory response in the uterus of cows carrying somatic cell nuclear transfer (SCNT), commonly known as cloned, pregnancies due to abnormalities in proteins expressed by placental trophoblast cells. Between 30 and 90 days the rate of pregnancy loss is 50-100% for SCNT compared to 2-10% for artificial insemination (AI) pregnancies. Abnormal communication between the maternal and fetal systems during placentation is a major cause of this loss. The trafficking of extracellular vesicles (EVs), membrane-bound cargo carriers, potentially represents …

Mapping Quaking Aspen Using Seasonal Sentinel-1 And Sentinel-2 Composite Imagery Across The Southern Rockies, Usa, Maxwell Cook, Teresa Chapman, Sarah Hart, Asha Paudel, Jennifer Balch

Aspen Bibliography

Quaking aspen is an important deciduous tree species across interior western U.S. forests. Existing maps of aspen distribution are based on Landsat imagery and often miss small stands ( < 0.09 ha or 30 m²), which rapidly regrow when managed or following disturbance. In this study, we present methods for deriving a new regional map of aspen forests using one year of Sentinel-1 (S1) and Sentinel-2 (S2) imagery in Google Earth Engine. Using observed annual phenology of aspen across the Southern Rockies and leveraging the frequent temporal resolution of S1 and S2, ecologically relevant seasonal imagery composites were developed. We derived spectral indices and …

Multifidelity Comparison Of Supersonic Wave Drag Prediction Methods Using Axisymmetric Bodies †, Troy Abraham, David Lazzara, Douglas Hunsaker

Mechanical and Aerospace Engineering Student Publications and Presentations

Low-fidelity analytic and computational wave drag prediction methods assume linear aerodynamics and small perturbations to the flow. Hence, these methods are typically accurate for only very slender geometries. The present work assesses the accuracy of these methods relative to high-fidelity Euler, compressible computational-fluid-dynamics solutions for a set of axisymmetric geometries with varying radius-to-length ratios (R/L). Grid-resolution studies are included for all computational results to ensure grid-resolved results. Results show that the low-fidelity analytic and computational methods match the Euler CFD predictions to around a single drag count (~1.0 × 10^–4) for geometries with R/L ≤ 0.05 …

All Current Publications

Normalizing the estate planning conversation can help eliminate emotional distance or fear when discussing important life planning matters. Approaching discussions in a loving and calm manner can bring family closer together and minimize or avoid contention and resentment. Talking about estate planning doesn’t have to be uncomfortable and emotional. Where possible, start conversations early to have a more positive experience, rather than planning at the time of a life crisis. If you have children, start these conversations when they are young to help normalize the process. The Estate Planning Toolkit is a helpful preparation resource that covers wills, trusts, life …

Examining Processes Of Change For Acceptance And Commitment Therapy And Cognitive Behavioral Therapy Self-Help Books With Depressed College Students, Carter H. Davis, Michael P. Twohig, Michael E. Levin

Psychology Faculty Publications

Given the prevalence of depression, it is worthwhile to consider a variety of treatment approaches to reach as many sufferers as possible, including highly accessible formats such as self-help books. Books based in acceptance and commitment therapy (ACT) and cognitive behavioral therapy (CBT) propose to treat depression through distinct processes of change, though the degree to which these treatments are distinguishable in this format is unclear. Furthermore, it is possible that some individuals may respond better to therapeutic processes from one approach over the other based on personal preferences. We tested the effects of ACT and CBT self-help books on …

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 …

“It’S Hard For Him To Make Choices Sometimes And He Needs Guidance”: Re-Orienting Parental Control For Children, Prakriti Dumaru, Hanieh Atashpanjeh, Mahdi Nasrullah Al-Ameen

Computer Science Student Research

With access to devices and online platforms at an increasingly younger age, it is essential to protect children from potential online risks. In our studies, we particularly focused the parents who have a child under 13 years of age. To this end, deriving from developmental psychology, we base our low-fidelity prototype design (termed as ‘treatment’) on a set of design principles focusing on open communication, instilling self-regulation, and availing granularity along with designs of existing Google’s parental control as a baseline. First, we conducted semi-structured interviews with 21 parents to understand their perceptions, including suggestions for design improvement within our …

Lessons From Immersive Online Collaborative Modeling To Discuss More Adaptive Reservoir Operations, David E. Rosenberg

Civil and Environmental Engineering Faculty Publications

This work had the purpose to provoke discussion about more adaptive reservoir operations. This work created online collaborative modeling environments by using web spreadsheets (Google Sheets) during a video conference session. In each session, up to 6 collaborators immersed in water user roles. Then the collaborators consumed, saved, and traded water in response to their available water, other choices, and real-time discussion of choices. The collaboration was an alternative to prior offline or high-performance computing efforts that programmed water allocation rules to try to satisfy forecasted water demands across hydrologic scenarios. The collaboration also differed from prior efforts that excluded …

Combining Empirical And Physics-Based Models For Solar Wind Prediction, Rob Johnson, Soukaina Filali Boubrahimi, Omar Bahri, Shah Muhammad Hamdi

Computer Science Faculty and Staff Publications

Solar wind modeling is classified into two main types: empirical models and physics-based models, each designed to forecast solar wind properties in various regions of the heliosphere. Empirical models, which are cost-effective, have demonstrated significant accuracy in predicting solar wind at the L1 Lagrange point. On the other hand, physics-based models rely on magnetohydrodynamics (MHD) principles and demand more computational resources. In this research paper, we build upon our recent novel approach that merges empirical and physics-based models. Our recent proposal involves the creation of a new physics-informed neural network that leverages time series data from solar wind predictors to …

Sustainability And Drivers Of Populus Tremuloides Regeneration And Recruitment Near The Southwestern Edge Of Its Range, Connor D. Crouch, Nicholas P. Wilhelmi, Paul C. Rogers, Margaret M. Moore, Kristen M. Waring

Aspen Bibliography

Quaking aspen (Populus tremuloides Michx.) ecosystems are highly valued in the southwestern United States because of the ecological, economic, and aesthetic benefits they provide. Aspen has experienced extensive mortality in recent decades, and there is evidence that many areas in Arizona, United States lack adequate recruitment to replace dying overstory trees. Maintaining sustainable levels of regeneration and recruitment (i.e. juveniles) is critical for promoting aspen ecosystem resilience and adaptive capacity, but questions remain about which factors currently limit juvenile aspen and which strategies are appropriate for managing aspen in an increasingly uncertain future. To fill these critical knowledge gaps, …
