Understanding Power Dynamics Of Latter-Day Saint Marriages In The United States Of America, Bonnie Young

All Graduate Theses and Dissertations, Fall 2023 to Present

Power sharing is a key feature of romantic relationships. It is important to understand how various groups navigate power sharing within their relationships. Thirty-one participants who belong to the Church of Jesus Christ of Latter-day Saints (16 women and 15 men) reported on their experience of power-sharing in marriage. In-depth individual and couple interviews revealed that couples engage in four individual and relational processes that impact and promote equality in marriage: systemic influences, self-in-relationship processes, relationship processes, and identity outcomes. These processes have important implications for future research and therapeutic practice with Latter-day Saint, religious, and secular couples.

Wild Water: Hydrosocial Dislocation, Dispossession, And The Symbolic Geographies Of The American West, Leonard Alexander Henderson

All Graduate Theses and Dissertations, Fall 2023 to Present

This dissertation investigates how the confluence of community change and water politics in the American West shapes a discussion about a Wild and Scenic designation for the Crystal River on Colorado’s Western Slope.

All Current Publications

Wildfires are a natural part of the western U.S. landscape and provide numerous benefits, including enhanced nutrient cycling and habitat rejuvenation. Utah’s fish populations evolved with wildfire as a common disturbance. However, the increasing size and severity of wildfires, combined with Utah’s heavily engineered and fragmented stream networks, pose a contemporary risk to fish populations. This fact sheet reviews wildfire impacts on erosion and Utah's watersheds and fisheries. It outlines measures we can take to prevent post-wildfire fish die-offs.

"...Anything My Friend Shares, I Would Want To Support Them By Clicking On It": Co-Designing Story-Based Interventions Against Clickbait For Teenagers, Ankit Shrestha, Audrey Flood, Bryson Hackler, Mahdi Nasrullah Al-Ameen

Computer Science Student Research

Teenagers' lack of digital sophistication and cyber hygiene makes them vulnerable to social engineering attacks, especially as they start using social media. Clickbait, one of such attacks, is primarily performed through social media to trick users into clicking on malicious links. With teenagers' increasing use of social media, clickbait poses a substantial threat to their online safety. The existing online safety measures for teens mainly focus on parental mediation, which can be perceived as restrictive and privacy-invasive. To this end, researchers recommended empowering teens to deal with online risks. In order to design such interventions for clickbait, we conducted co-design …

Psychological Flexibility As A Mechanism Of Change In Online Act Among Adults Living With Chronic Health Conditions, Francesca M. Knudsen, Marissa L. Donahue, Korena S. Klimczak, Ty B. Aller, Michael E. Levin

Psychology Faculty Publications

Living with a chronic health condition (CHC) can negatively impact quality of life (QoL) through a complex interaction of mental health challenges, functional limitations, and disease management demands. Acceptance and Commitment Therapy (ACT) is a transdiagnostic approach that shows promise in addressing shared challenges across various CHCs by fostering psychological flexibility (PF). PF has been associated with improved QoL and functional outcomes and reduced psychological symptoms in individuals living with specific CHCs; yet its mediating role in these outcomes remains underexplored. This secondary analysis examined whether changes in PF mediated improvements in QoL, psychological symptoms, and functional impairment among individuals …

A Review Of Automation In Small Satellite Operations, Joseph Melville, Andrew Narvaez, Lee Jasper

Weaning a beef calf is likely the most stressful event in the animal’s life. Future growth and reproductive performance can be compromised by health challenges encountered through the weaning process. Consequently, proper management aimed at reducing stress and preparing the beef animal for the next stage of production is critical to reach its genetic potential. Proper management involves applying good animal husbandry techniques, using sound science in developing health and feeding protocols, and implementing low-stress animal handling practices.

Aspen Impedes Wildfire Spread In Southwestern United States Landscapes, Matthew P. Harris, Jonathan D. Coop, Jared A. Balik, Jessika R. Mcfarland, Sean A. Parks, Camille S. Stevens-Rumann

Aspen Bibliography

Aspen (Populus tremuloides) forests are generally thought to impede fire spread, yet the extent of this effect is not well quantified in relation to other vegetation types. We examined the influence of aspen cover on interpolated daily fire spread rates, the relative abundance of aspen at fire perimeters versus burn interiors, and whether these relationships shifted under more fire-conducive atmospheric conditions. Our study incorporated 314 fires occurring between 2001 and 2020 in the southwestern United States and a suite of gridded vegetation, topography, and fire weather predictor variables. We found that aspen slows fire progression: as aspen cover …

Biology Faculty Publications

Lavandula angustifolia Mill., lavender, is an aromatic plant in the Lamiaceae family. Lavender, which is native to the Mediterranean region but cultivated throughout the world, is an important economic plant. Several studies have investigated two aspects of this aromatic plant: (1) which pollinators, particularly bees, pollinate lavender, and (2) the composition of lavender essential oil. However, little research has been conducted to investigate how pollination affects either the yield or phytochemistry of lavender. The current study, which was conducted in North America, investigates which bee species visit lavender and how pollination affects plant chemistry, specifically the essential oil produced by …

Transforming Care: An Academic And Community Symposium On Transgender Care And Experience, Alison Sutton-Ryan, Kimberly Van Vulpen

Transforming Communities

Background: Transgender experience is often excluded from education and training. An emphasis has been often placed on sexual identities instead of gender differences rendering transgender care invisible in the healthcare system (Gahagan & Colpitts 2017). Lack of education and training has created significant barriers to accessible gender-affirming care, contributing to disproportionately high levels of discrimination for transgender individuals seeking medical services (Redcay et al., 2021). Purpose: The Interprofessional Education Symposium on Transgender Care and Experience was an innovative initiative developed by the newly formed Transgender Interprofessional Care Team (TICT) at a medium-sized suburban university. This collaborative team, comprising key …

A Review Of Plant–Microbe Interactions In The Rhizosphere And The Role Of Root Exudates In Microbiome Engineering, Anagha Wankhade, Emma Wilkinson, David W. Britt, Amita Kaundal

Biological Engineering Student Research

Microbial interactions within the rhizosphere are fundamental to plant health, influencing nutrient availability, stress tolerance, and pathogen resistance. Beneficial microbes, such as plant growth-promoting microbes (PGPMs), including bacteria and mycorrhizal fungi, enhance plant resilience through mechanisms like nutrient solubilization, phytohormone production, and pathogen suppression via antimicrobial compounds and siderophores. Root exudates, composed of sugars, organic acids, and secondary metabolites, act as chemoattractants that shape the rhizosphere microbiome by recruiting beneficial microbes. Microbial metabolites can, in turn, modulate plant physiology and exudate profiles, thereby reinforcing mutualistic interactions. Stress conditions alter exudate composition, enabling plants to attract specific microbes that aid in …
