Wildfire And Water Security: Post-Fire Erosion And Sedimentation Threaten Utah's Reservoirs, Quinn Olpin, Kendall Becker, Scott Hotaling, Aish Chandrasekaran, Patrick Belmont

All Current Publications

As an arid state with limited water, Utah relies heavily on reservoir storage to maintain its water supply throughout the year. This vital water storage, however, is increasingly at risk due to contemporary wildfires. Wildfires pose a risk to water storage because after vegetation burns, erosion typically increases. Eroded soil can be carried by rivers and deposited into reservoirs where it accumulates as sediment, reduces water storage capacity, clogs dam outlets, and degrades water quality. Identifying which watersheds are most vital to maintaining Utah’s water supply, are most threatened by wildfires, and are most prone to high levels of post-fire …

Post-Wildfire Erosion And Sedimentation: An Escalating Threat For Utah Fisheries, Colton James, Kendall Becker, Scott Hotaling, Aish Chandrasekaran, Alex Fiedler, Timothy E. Walsworth, Patrick Belmont

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

On The Connection Between Sport And Morality: Does Russell’S ‘Continuity Thesis’ Hold Water?, Cesar R. Torres, Francisco Javier López Frías

Kinesiology and Health Science Faculty Publications

The connection between sport and morality is a key focus of J. S. Russell’s scholarly work. He rejects the ‘separation thesis’, which claims that sport has a significant degree of autonomy and thus its own set of values separate from those of society. Instead, he supports the ‘continuity thesis,’ which suggests that the moral values at the heart of sport reflect more basic moral values found outside its boundaries. Therefore, for Russell, individuals involved in sport do not leave ordinary morality to enter a separate sporting one. Rather, they engage in a social practice whose core moral principles are extensions …

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 …

Marketing and Strategy Faculty Publications

According to the World Health Organization, “mental health is a state of well-being that enables people to cope with the stresses of life, realize their abilities, learn well and work well, and contribute to their community.”¹ Based on a 2025 ranking from WalletHub, Utah is the 4th “Happiest” state in the nation, so one might draw the conclusion that Utahns experience good mental health. However, the rankings also reveal that Utah does not perform as well in the “Emotional & Physical Well-Being” category (in 27th place).² Because mental health is an important indicator of overall well-being, this report …

Environmental And Social Values Are Important To All Utahns, But Conservative Utahns Are More Likely To Prioritize The Economy, Sarah E. Wilson, Jessica D. Ulrich-Schad

Utah People and Environment Poll (UPEP)

In the political landscape of modern America, few would disagree that people on either end of the political spectrum exhibit differences in priorities and values. Since the 1970s, polarization between left and right-leaning individuals and decision-makers regarding environmental matters has grown significantly.¹ For example, a 2023 Gallup Poll found that 78% of liberals favored prioritizing the environment over economic concerns, compared to just 20% of conservatives - representing the largest partisan gap since Gallup began including the question in their poll in 1984.²

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 …
