Utahns’ Generally Agree On Top Environmental Concerns, But Climate Change And Related Issues Reveal Political Polarization, Sarah E. Wilson, Jessica Ulrich-Schad

Utah People and Environment Poll (UPEP)

Utah is renowned for its unique landscapes and abundant opportunities to connect with the natural environment. However, the state is currently grappling with serious environmental challenges, including poor air quality, dwindling water supplies, and the alarming desiccation of the Great Salt Lake. These and other issues have major ecological and economic implications, and combating them will likely require large scale efforts. However, rising levels of political polarization are a common problem in the United States that many feel stifles our ability to combat societal problems, including those related to the environment and human health.

Condition And Management Futures In A Quaking Aspen Recreation Area. Final Report To Snyderville Basin Special Recreation District, Paul C. Rogers, Georgie Corkery, Anna B. Miller

Aspen Bibliography

In partnership with Snyderville Basin Special Recreation District (SBSRD), we undertook a study of ecological conditions and user preferences within a quaking aspen recreational destination forest. The location, in two sections know as Run-A-Muk and Right Turn Sage (RAM/RTS), has experienced some forest die-off in the principally aspen dominated forest dissected by ski, bike, and hiking trails. Graduate student Georgie Corkery led the study and successfully completed a Master's degree, in addition to providing needed information to SBSRD regarding the status, uses, and preferred actions at this facility. Key outcomes regarding aspen conditions include assigning causal factors—ungulate browsing and elevated …

Designing A Robust Lab Scale Electrocoagulation Reactor For Removal Of Micro- And Nanoplastics From Drinking Water, Emmanuel Louis Aduhene

All Graduate Reports and Creative Projects, Fall 2023 to Present

The widespread occurrence of micro and nanoplastics in drinking water sources could cause serious public health issues. These plastics particles, products of industrial operations and weathering of larger plastics, can interact with other contaminants in the environment, leading to more severe environmental pollution. Present drinking water treatment technologies were designed to remove suspended colloids. However, due to the distinct chemical and physical properties of micro and nanoplastics from conventional colloids, it is challenging for traditional chemical coagulation/flocculation/sedimentation process to achieve satisfying removal performance. This report investigates a design of a lab-scale electrocoagulation reactor for the removal of nanoplastics from drinking …

The Restorative Design Scale (Rds) An Assessment Guide: Measuring The Potential For Mental Restoration In Urban Green Spaces, Corinne Bahr

All Graduate Reports and Creative Projects, Fall 2023 to Present

Mental health is a growing national priority, and green space has been proven to benefit mental health. There is a massive amount of recent research studying the influence of green space characteristics on mental health improvement and restoration. However, professional landscape architects, designers, and planners involved in creating physical spaces have not been able to assess and therefore prioritize mental health in their designs due to the sheer quantity of information that has not yet been synthesized and applied efficiently. The Restorative Design Scale (RDS) Assessment condenses this material into a scientifically inspired resource for professionals to easily understand and …

Quantifying The Impact Of Rain-On-Snow Induced Flooding In The Western United States, Emma M. Watts

All Graduate Theses and Dissertations, Fall 2023 to Present

Serious flooding can happen when rain falls on snow, which we call a rain-on-snow (ROS) event. Increasing our understanding of the behavior of floods resulting from ROS events can help us design better systems to manage flood water and prevent it from causing damage. This thesis explores how ROS events affect streamflow in the Western United States by examining the weather conditions that precede a streamflow surge. We classify stream surges as ROS or non-ROS induced based on these weather conditions, which helps us separate floods caused by ROS events from those caused by other factors. By comparing these different …

Testing For Patterns Of Deformation From The Yellowstone Hotspot Along The Gallatin River, Sw Montana, Jack Willard

All Graduate Theses and Dissertations, Fall 2023 to Present

Yellowstone has fascinated humans for thousands of years. Geologists have addressed many of the region’s mysteries, including the underlying mantle hotspot, the chain of calderas tracking the motion of the North American Plate over this hotspot, and the risks posed by the super volcano. However, the way that the hotspot impacts regional tectonics and topography remains under-studied. Influential previous work recognized the Yellowstone Crescent of High Terrain (YCHT), an arc of high topography around the Yellowstone Plateau with limbs extending to the west and south into central Idaho and northern Utah. The YCHT is also hypothesized to be the pattern …

Script Fading And Training: Evaluating The Necessity Of Visual Cues To Teach Contextually Appropriate Play Commenting, Devanio J. Cousins

All Graduate Theses and Dissertations, Fall 2023 to Present

Autism Spectrum Disorder (ASD) is marked by many areas of need, including play and communication. These areas of concern can have a negative impact on a child's development. Applied behavior analysis, specifically script training and fading procedures, has shown promise in teaching communication during play to young autistic children. However, traditional script training and fading methods have some limitations, including the skills the children already possess to learn the scripts and the resources needed to teach the scripts. Recent studies have shown that script frames can be taught without using traditional training formats (i.e., text, auditory) but by using generic …

Peer Relationships, Social Identity, And Motivational Experiences In Youth Sport, Justin T. Worley

All Graduate Theses and Dissertations, Fall 2023 to Present

Organized sport is a setting in which youth can make friends and explore their identity. Teammate relationships may make important contributions to athletes’ social identity (i.e., their psychological connection to their sport team) and their motivation for sport. This idea was tested across three studies. A review of literature was conducted in study one to identify factors that may contribute to athlete social identity. Seven categories were identified across 60 studies including leadership factors, environmental factors, personal factors, team factors, interventions, moral factors, and interpersonal factors. Less than a third of these studies were conducted with youth athletes and interpersonal …

Data-Driven Techno-Economic Analysis, Optimization, And Uncertainty Quantification Of Integrated Energy Systems In Deregulated Electricity Markets, Jacob A. Bryan

All Graduate Theses and Dissertations, Fall 2023 to Present

Electricity is a ubiquitous energy source in daily life, powering everything from stovetops and cellphones to vehicles and industrial processes. While wind and solar power have become increasingly common sources of electricity, the majority of electricity is still produced by burning fossil fuels, releasing greenhouse gases and propelling climate change. Wind and solar power cannot economically replace these fossil fuel energy sources on their own because they do not produce consistent power; the wind must be blowing, and the sun must be shining for them to make electricity. Nuclear power is a reliable source of energy that does not generate …

Constraining Decadal-Scale Erosion And Delivery Of Post-Wildfire Debris Flow Deposits, Casey Langstroth

All Graduate Theses and Dissertations, Fall 2023 to Present

Debris flows generated from wildfire pose significant risk to increased sedimentation to instream river networks, degradation of water quality, and accumulated sediment behind downstream reservoirs. Despite an abundance of research investigating the probability of debris flow generation, the constraints on deposit initial volume, and most recently the initial grain size distribution, there remains a significant knowledge gap in understanding the temporal scale at which debris flows supply sediment to river networks after deposition. To provide reliable estimates of sediment delivery from debris flow deposits over time, two important metrics must be constrained: 1) how does sediment delivery to river networks …

Aggregate And Disaggregate Effects Of The Us-China Trade War On Us Agriculture, Aflatun Kaeser

All Graduate Theses and Dissertations, Fall 2023 to Present

In 2018 and 2019, the US-China trade war caused a significant shift in US agricultural trade dynamics. This thesis conducts an aggregate and disaggregate analysis of the impact, using event study analysis to reveal varying effects on US agricultural exports, with a substantial effect on Soybean and Dairy exports. The analysis also found that there are heterogeneous effects on other agricultural commodities such as fruits, wheat, and tree nuts. Using Bayesian Structural Time Series Modeling, the study finds a 29% decline in soybean exports during the trade war period. These findings underscore the importance of considering the heterogeneity in the …

A Mass Balance Model Of The Great Salt Lake, Ut With Adaptive Management Applications, Diana Dunn

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt, Utah, USA is a saline lake that provides critical habitat for ecologic communities and generates $1.3 billion annually. It has gone through detrimental change since the 20^th century. Streamflow reaching the lake has been decreased by upstream withdrawal for industrial and municipal use, causing the lake level to drop and salinity to increase to unhealthy levels. Further, in 1959, it was segregated into north and south sections by a railroad causeway. Due to the causeway and limited exchange of water through two bridges, the lake sections have significantly different water surface elevation and salinity levels. The …

Moose Movement In An Urbanizing Landscape, Lucian R. Mcdonald

All Graduate Theses and Dissertations, Fall 2023 to Present

Humans disturb the environment in specific places and at specific times. As wildlife learn to navigate these disturbances, they react as they would to the risk of predation. Wildlife biologists can identify where and when these disturbances will lead wildlife to congregate by comparing geospatial data, such as metrics that represent vegetation, topography, or other environmental conditions, to known locations of the animal(s) in question. In Chapter I, I discuss the impact of human disturbances, like urbanization and roads, on wildlife behavior. In Chapter II, I compare the risk of moose-vehicle collisions (MVCs) to moose selection of urbanized landscapes to …

All Graduate Theses and Dissertations, Fall 2023 to Present

This dissertation analyzes Chesapeake Bay Watershed (CBW) agriculture by exploring residents' views on water quality issues, agriculture-related conflict, and farmers' adoption of nutrient management plans. The following questions were asked: What is the level of concern among non-agricultural and agricultural residents about water quality issues in local streams and waterways and the CBW, and to whom do the two groups attribute water quality problems? What are nonfarming residents' and farmers' levels of support for various interventions outlined in previous research on water quality issues in local streams and waterways and the CBW? What is the level of nonfarming residents' and …

Channel Dynamics In Response To Compounding Hydrogeomorphic Disturbances In A Steep Burned Watershed, Paxton Ridgway

All Graduate Theses and Dissertations, Fall 2023 to Present

Wildfires significantly increase sediment input to rivers through various pathways, including post-fire debris flows. Understanding how mountain rivers respond to these sediment inputs is crucial for predicting and managing downstream impacts on infrastructure, water security, and aquatic habitats. While the causes and characteristics of post-fire debris flows have been extensively studied, the morphological changes in downstream fluvial channels remain poorly understood. This study uses scripted spatial analysis toolsets, high-resolution pre- and post-fire DEMs, repeat cross-sectional surveys, time-lapse footage, and pebble counts to document channel responses to sediment supply in a burned steep mountain stream in the upper Colorado River Basin, …

All Graduate Theses and Dissertations, Fall 2023 to Present

Battery-electric buses (BEBs) have become increasingly common in recent years, as transit agencies around the world seek to reduce their carbon emissions. Although many agencies and governments have set ambitious climate goals pushing for increased adoption of BEBs, some agencies face difficulty transitioning their fleets to this technology. This study seeks to understand the challenges faced by these agencies, as well as their motivations for adopting BEBs. Researchers conducted a series of interviewers with twelve transit leaders representing ten transit agencies who were leading BEB adoption programs, asking questions about their experiences trying to implement this technology. The interviewees stated …

Investigating The Biochemical Aspects Of Meat Tenderness, Chandler D. Stafford

All Graduate Theses and Dissertations, Fall 2023 to Present

Of all the attributes that define beef's eating quality, tenderness stands out as one of the most important. Previous studies have shown that consumers are willing to pay a premium for beef that is guaranteed to be more tender and are more likely to purchase that product repeatedly. Yet, due to the influence of numerous internal and external factors, controlling and predicting tenderness remains to be difficult. However, among these factors, meat aging is the primary contributor to end-product tenderness, as it is recognized for breaking down muscle tissue via enzymes present within the muscle. The activity of these enzymes …

Westward Words: An Exploration Of Western Beats And Their Legacy, Brenna Jones

All Graduate Theses and Dissertations, Fall 2023 to Present

This thesis examines the art, poetry, and experiences of western Beats or Beatniks. Also known as the Beat Generation, this literary movement is traditionally associated with East Coast writers. However, a prominent Beat culture was also present on the West Coast throughout the 1950s and 1970s. The thesis explores how the West influenced the literature and art produced by Beats during this time.

Interpretable And Robust Deep Anomaly Detection, He Cheng

All Graduate Theses and Dissertations, Fall 2023 to Present

Anomaly detection is crucial in fields like cybersecurity, healthcare, and finance, as it helps identify unusual or potentially harmful events in data. With the rise of deep learning, advanced models have been developed for anomaly detection, but they often operate as "black boxes" that lack transparency and can be susceptible to malicious attacks. My research addresses these issues by creating methods that make deep learning-based anomaly detection more understandable and by investigating how such models can be compromised by backdoor attacks.

To improve transparency, I propose three methods that explain how these models detect anomalies. The first method, called Anomalous …

Ecological Interactions Of Cougars, Deer, And Wild Pigs In The Central Coast Range, California, Mitchell A. Parsons

All Graduate Theses and Dissertations, Fall 2023 to Present

Wild pigs are an introduced species in the Americas that negatively affect ecosystems in many ways. Previous research has documented their negative effects on water quality and vegetation and their potential to spread disease among wildlife, domestic animals, and humans. However, how wild pigs affect predator-prey interactions between native wildlife has received little attention. This research explores multiple interactions between wild pigs, a native predator (cougars), and a native prey (black-tailed deer). First, I studies cougar diet to understand how frequently pigs are used as prey. During this project, I also placed wildlife cameras at cougar killed prey to monitor …

God's Laborers: Missionary Work And Imperialism In The Congo From 1878-1908, Ana Peterson

All Graduate Theses and Dissertations, Fall 2023 to Present

In 1878, Henry Craven opened the first Protestant mission in the Congo. The Livingstone Inland Mission created multiple stations along the Congo River to reach the interior. It stayed active for six years before transferring its stations to Swedish and American missions. Five years after its closure, a sister mission, the Congo Balolo Mission, resumed efforts to teach the people living in the interior. This thesis explores the evolving reaction of the missionaries to state violence. It argues that these missionaries initially supported imperial violence that enforced laws that aligned with their beliefs, such as removing the slave trade. Once …

Analysis Of A Gravity Wave Horizontal Blocking Event Using Hodograph Techniques Applied To Sodium Lidar Data, Neal R. Criddle

All Graduate Theses and Dissertations, Fall 2023 to Present

Atmospheric gravity waves are ubiquitous and important events in Earth’s atmosphere with impacts on space weather and associated technological effects. The population of gravity waves is determined by their formation mechanisms, and their interactions with the background atmosphere. These gravity waves transport energy and momentum into the near Earth space environment, and are responsible for movement of chemical species. Predicting the occurrence of space weather effects, then, is in part a process requiring the characterization of gravity waves. Case studies of unique and interesting gravity wave events are an important part of this process. These allow for the investigation of …

Detecting Community-Level Ethnic Variation Through Classic Vernal Style Rock Art, Victoria Ramirez

All Graduate Theses and Dissertations, Fall 2023 to Present

The Uinta Basin in Northeastern Utah was where farming first took hold in the far north of western North America. This shift from hunting to farming saw the rise of many farming communities among the Fremont people. These communities left behind stunning rock art known as the Classic Vernal style. Recent studies suggest that these communities were made up of two different groups who came from the Four-Corners area around AD 300, bringing farming with them. This idea means that different cultural groups may have created the Classic Vernal style rock art in the Uinta Basin. By looking closely at …

Development Of A Subsurface Water Velocity And Quality Measurement Payload For Suas, Mitchell Bailey

All Graduate Theses and Dissertations, Fall 2023 to Present

Aquaculture farms, like oyster farms, often use outdated techniques to measure the quality of their waters. These techniques are often stationary or are deployed by an operator who may struggle to reach a location depending on conditions like the presence of a storm or low tide. This creates data sets with gaps over time and across the area of the farm, meaning the data cannot be used to model the standard farm conditions. An Uncrewed Aerial System (UAS) payload is developed in this paper that is capable of measuring depth-velocity profiles through the use of a tethered velocity sensor. The …
