#Thisiswhatanxietyfeelslike: Twitter Users’ Narratives About The Interpersonal Effects Of Anxiety, Raechel B. Russo

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Tweets containing the popular hashtag #ThisIsWhatAnxietyFeelsLike were analyzed in this study. Six themes emerged from our phenomenological analysis of relational experiences with anxiety as conveyed by the Twitter users including: (a) deflated self in relation to others and their perceptions; (b) fear, worry and avoidance behaviors that influence relationships; (c) negative emotional responses leading to feeling misunderstood, lonely, and like a failure (self-fulfilling prophecy); (d) social triggers; (e) anxiety management strategies; and (f) things for others to avoid. This paper will highlight how anxiety symptoms affect relationships and interactions with others, and implications for clinical work and future research.

An Evaluation Of Arthropod Assemblages In Great Salt Lake Wetland Habitats: Differences Between Native And Invasive Vegetation And Implications For Restoration, Emily E. Leonard

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Wetlands provide important habitat for various birds. Invasive plants can disrupt wetland food webs by altering the arthropod assemblages (invertebrate animals such as spiders, mites, insects, centipedes, and millipedes) on which these birds rely. However, differences between the wetland arthropods found in invasive vs. native vegetation are poorly defined. Wetlands are often managed for the creation of bird habitat through invasive species removal and native plant revegetation, yet few studies have examined the effects of these restoration methods on arthropod bird food sources. Phragmites australis (common reed), is an aggressive grass species in wetlands surrounding the Great Salt Lake, Utah, …

A Study Of Potential Security And Safety Vulnerabilities In Cyber-Physical Systems, Ali Al-Hashimi

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The work in this dissertation focuses on two examples of Cyber-Physical Systems (CPS), integrations of communication and monitoring capabilities to control a physical system, that operate in adversarial environments. That is to say, it is possible for individuals with malicious intent to gain access to various components of the CPS, disrupt normal operation, and induce harmful impacts. Such a deliberate action will be referred to as an attack. Therefore, some possible attacks against two CPSs will be studied in this dissertation and, when possible, solutions to handle such attacks will also be suggested.

The first CPS of interest is vehicular …

Forest Grouse Ecology And Management In The Bear River Range Northern Utah, Skyler Y. Farnsworth

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

To better manage dusky grouse (Dendragapus obscurus) and ruffed grouse (Bonasa umbellus), hereafter forest grouse, managers require better information on forest grouse population status and habitat selection. To address this need, from 2015-2017, I conducted research on a sympatric populations inhabiting the Bear River Range of northern Utah to develop a breeding survey protocol, assess habitat selection, evaluate dusky grouse response to livestock grazing, and determine hunter harvest rates.

The breeding census protocol that I developed compared listening intervals with and without electronic playback calls at designated survey stop locations. Using digital mapping software, I plotted …

Interspecific Differences In Stressor Tolerance Drive Community-Level Changes In A Small Aquatic Ecosystem, Jennifer M. Weathered

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The global human population is expected to reach 9.8 billion by 2050 and an increase in food yield will be needed to provide for the future generations. Insects are among the biggest threats to food production and are therefore the subject of intense chemical control through the application of pesticides. The ability of insects to evolve resistance to pesticides after repeated use has been documented. However, how evolved responses affect individuals’ behaviors, their interactions with others, and how these factors impact overall patterns in distribution remains relatively unexplored in the bromeliad.

The aquatic insect communities housed in water-holding tropical plants …

Pollution Prevention And Water Reuse At Utah Department Of Transportation Facilities, Amanda Stoudt

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As stormwater flows over roads, sidewalks, and other impervious surfaces, it picks up pollutants that are deposited on these surfaces. One common pollutant transported by stormwater is road salt. While the application of road salt is crucial for wintertime public safety, road salt has a host of negative environmental impacts. Road salt has been linked to increasing levels of dissolved solids in groundwater, vegetation damage, and behavioral changes in aquatic organisms. Studies have shown that these impacts are concentrated around salt storage facilities. As a result, the United States Environmental Protection Agency issued many state departments of transportation municipal separate …

An Evaluation Of Management Options For The Clover Root Curculio (Sitona Hispidulus), A Pest Of Alfalfa (Medicago Sativa) In The Intermountain West, Kaitlin A. Rim

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The clover root curculio (CRC) is an important forage pest throughout North America. Extensive larval feeding on host roots has been associated with reduced stand establishment, disruption of nutrient and water uptake, increased secondary plant pathogen infection, decreased winter plant survival, and reductions in forage quality and yield. Due to the hidden nature of larvae in the soil, CRC is often overlooked and integrated pest management programs are limited as there is a lack of management options. First, I surveyed northern Utah alfalfa for CRC natural enemies, particularly insect-attacking nematodes and fungi (entomopathogens) that could be used in biological control …

Development And Validation Of A Synchronous Model To Simulate Skeletal Muscle Damage Due To Spaceflight Ionizing Radiation And Microgravity, Lori M. Caldwell

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Astronauts traveling or researching in space are subject to a harsh environment that includes high levels of ionizing radiation and microgravity. Ionizing radiation is dangerous to overall health because it causes double-stranded DNA breaks, increases the production of free radicals or reactive oxygen species, and leads to an enhanced risk of cardiovascular disease and cancer over a person’s lifetime. Similarly, microgravity is hazardous to astronaut health because humans require gravity to maintain a healthy heart and muscular and vascular systems.

Both ionizing radiation and microgravity have been studied individually in previous research, but there is a lack of information on …

Do Didymosphenia Geminata Blooms Affect Fishes In The Kootenai River Basin?, Niall G. Clancy

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Didymosphenia geminata (Didymo) is a nuisance algae that can cover entire streambeds under certain environmental conditions. Numerous studies have shown that it changes the composition of stream invertebrates. Fishes in many headwaters are known to feed almost exclusively on invertebrates. Thus, there is concern changes to the amount or type of invertebrates caused by Didymo blooms will impact fishes such as trout, charr, and sculpin. In the Kootenai River basin of Montana and British Columbia, we examined stream invertebrates and fish diets, condition, and growth across 25 streams during the summers of 2018 and 2019. The severity of Didymo blooms …

It was found in the course of this study …

Artisan: On Bread And A Meaningful Life, Emerson James

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In 1944, three decades before the start of the artisanal bread movement, H. E. Jacob published Six Thousand Years of Bread: Its Holy and Unholy History capturing bread’s cultural, political, religious, and technological impacts over time. In the introduction of the 2007 edition of the text, prominent American baker Peter Reinhart wrote that bread is “inextricably woven into our cultural and personal histories.” Reinhart notes that while bread does have its own story, “it is also the medium through which so many other stories are told: stories of escape from bondage; of historical and political battles ...; of the intermingling …

Relationship Quality Before, During, And After Stepfamily Education: A Latent Trajectory Analysis, Bryan K. Spuhler

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The purpose of this study was to explore the trajectories of relationship quality for a sample of 777 adult participants attending the Smart Steps: Embrace the Journey stepfamily relationship education course. Rather than assume that all program participants had similar relationship quality trajectories by averaging their scores together in a growth curve analysis, growth mixture modeling was used to allow for a variety of sub-groups (classes), each with a unique trajectory. A prevention science approach was then taken to address possible predictors of each trajectory class in order to identify the risk and protective factors that influence participants’ trajectories.

Nanotextural And Nanochemical Constraints On The Role Of Heat In The Development Of Crystalline-Hosted, Silica-Rich Fault Mirrors In The Wasatch Fault Damage Zone, Utah, Usa, Leah M. Houser

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Earthquakes occur on faults, or rock that has experienced displacement at depth. Experimental work on a range of rock types reveals that >90% of earthquake energy on fault surfaces is given off as heat. Heat weakens rock and promotes earthquake rupture propagation. Thin (<0.5mm), high-gloss, "polished", light-reflective exposed fault surfaces are called fault mirrors (FMs). Fault mirrors may record rapid thermal, textural, and chemical changes that occur during an earthquake event.

The Wasatch Mountains are a N-S trending mountain range in Northern Utah that are the backdrop for Salt Lake City, Provo, Ogden, and Brigham City. This mountain range is currently built by the active Wasatch fault, and includes the exposed Wasatch fault damage zone. Many segments of the Wasatch fault are overdue for a potentially catastrophic …

Salinity Tolerance In Kentucky Bluegrass Hybrids, Paul G. Harris

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Diminishing water sources in the Intermountain West have led to increased use of alternative sources of water. These sources, such as reclaimed water, generally have elevated salinity levels that may slow growth, and cause a decline in turfgrass quality. Kentucky bluegrass (Poa pratensis L.) is sensitive to salt stress, but is otherwise very well adapted to many turfgrass areas because of its dark color, durability, ability to recover from wear, and soft texture. Because of these positive traits, it has been the subject of selection for salt tolerance. This study was designed to evaluate the salt tolerance of hybrids …

Predicting The Impact Of Weather On Rural Travel Times Using Now-Cast Weather Forecast Data, Manish Meshram

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In the states which record extreme weather conditions and high snow in winters, the travel time to drive between cities can get highly affected due to these bad weather conditions. The present solutions to tackle this problem are largely flow or time related and do not take weather conditions into account while making the predictions about travel time. Also these solutions can mostly be used for real time travel and not the future travel. In addition to that, the studies that have been done in this space are mostly for urban travel times but most parts of the interstate highways …
