Wildfire In The West: How Megafires And Storm Events Affect Stream Chemistry And Nutrient Dynamics In Semi-Arid Watersheds, Trevor William Crandall

Theses and Dissertations

Climate change is causing larger wildfires and more extreme precipitation events throughout the world. As these ecological disturbances increasingly coincide, they are altering lateral fluxes of sediment, organic matter, and nutrients. Increased lateral flux of nutrients could exacerbate eutrophication and associated harmful algal blooms, and increased sediment and organic matter flux could degrade the water supply. Here, we report the immediate stream chemistry response of watersheds in central Utah (USA) that were affected by a megafire followed by an extreme precipitation event in 2018. The wildfires burned throughout the summer of 2018 until the remnants of Hurricane Rosa released torrential …

Diagnosis And The Role Of Chemokine Receptors In Alzheimer's Disease, Josue David Gonzalez Murcia

Theses and Dissertations

Alzheimer’s disease (AD) is the most common neurodegenerative disorder and is the main cause of dementia in the elderly population. AD is pathologically characterized by the accumulation of amyloid plaques and neurofibrillary tangles that results in neurodegeneration and loss of memory function. However, diagnosis of AD and characterization of biological mechanisms that lead to pathology and modulate risk for disease has proven to be extremely difficult. Cerebrospinal fluid (CSF) contains critical biomarkers for AD such as levels of amyloid beta (Aβ) phosphorylated-tau (p-tau), total-tau (t-tau), and neurofilament light chain (NfL). The CSF levels of these biomarkers are useful in determining …

Does Inhibitory Control Training Reduce Weight And Caloric Intake In Adults With Overweight And Obesity? A Pre-Registered, Randomized Controlled Event-Related Potential Study, Kaylie A. Carbine

Theses and Dissertations

Overweight and obesity are prevalent public health problems that impact physical, mental, and social health. Many studies have evaluated weight loss treatments, but most individuals are unsuccessful at maintaining weight loss long-term. Behavioral and cognitive interventions may be effective in promoting weight loss and weight loss maintenance. One cognitive intervention that has shown potential success in reducing weight and caloric intake is inhibitory control training (ICT). ICT involves trainings where individuals are asked to repeatedly withhold dominant responses to unhealthy or high-calorie food images in an effort to increase food-related inhibitory control abilities. Reductions in caloric intake or weight may …

Rage And Gas6/Axl Signaling In Obstetric Complications, Kelsey May Hirschi Budge

Theses and Dissertations

Current research spans a wide range of objectives whose diversity includes the understanding of global epidemiology and the detailing of molecular interactions leading to specific pathologies. This work aligns more closely with the goal of mechanistic clarity by elucidating several aspects of signaling pathways involved in inflammatory and obstetric pathologies. Prior research has confirmed the role of Receptors for Advanced Glycation End-Products (RAGE) activation in signaling leading to chronic inflammation such as that observed in chronic obstructive pulmonary disease (COPD). RAGE activation has also been identified in other disease states including diabetes, Alzheimer’s disease, osteoarthritis, and cancers. We examined the …

The success of these YouTube stars has led them to land roles on TV and in films, launch music careers, write …

Physician Behaviors, Nursing, And Other Obstacles In End-Of-Life Care: Additional Critical Care Nurse Perceptions, Elizabeth Elouise Willmore

Theses and Dissertations

Background: Critical Care Nurses (CCNs) frequently provide end of life (EOL) care in intensive care units (ICUs). Barriers to EOL care in ICUs exist and have been previously published, but qualitative reports from CCNs themselves remain scarce. Qualitative data exploring barriers faced during ICU EOL care may increase awareness of obstacles and help remove them. Objective: Excluding family experiences, what are the major themes recounted by CCNs when asked to share common obstacles experienced in providing ICU EOL care? Methods: Members of the American Association of Critical-Care Nurses were randomly surveyed and responses to a single qualitative question were used. …

The Roles Of Moral Anger, Empathy, And Self-Efficacy In Persuading Prosocial Activism, Erin Lurae Willder

Theses and Dissertations

This study examined how nonprofits can use video narratives to elicit young individuals' emotions and persuade them to support a cause; in particular this study analyzed variables of elicited moral anger, sense of self-efficacy, empathic connection, and prosocial persuasion. Undergraduate participants (n = 160) viewed a two-minute PSA depicting scenes of domestic violence escalation in a young married couple's apartment. Participants completed scale responses that demonstrated a positive correlation between message-induced state empathy and moral anger as well as a positive relationship between state empathy and activist tendencies. As in other studies framed by the anger activism model (AAM), high …

Forgiveness And Gratitude As Mediators Of Religious Commitment And Well-Being Among Polynesian Americans, Davis Kealanohea Kane

Theses and Dissertations

An abundance of research has investigated well-being as it relates to religiosity and positive traits, with most research indicating that both relate to improvements in well-being. Moreover, several studies provide evidence for statistically significant relationships between religiosity and specific positive traits, including forgiveness and gratitude. However, few research studies have investigated how increases in positive traits might explain why religiosity enhances well-being. In addition, few studies within the religious and positive psychological literature have included adequate sampling from ethnic/racial minority populations residing in the U.S. As a result, investigations on how ethnic identity interacts with religious and positive psychological variables …

College Counseling Center Treatment Outcomes: A Comparison Of Student Athletes And General Population Students, Mariah M. Bullock

Speech Exemplar And Evaluation Database (Seed) For Clinical Training In Articulatory Phonetics And Speech Science, Marisha Speights Atkins, Dallin J. Bailey, Suzanne E. Boyce

Faculty Publications

One challenge faced by teachers of phonetics, speech science, and clinical speech disorders courses is providing meaningful instruction that closes the theory to practice gap. One barrier to providing this type of deep learning experience is the lack of publicly available examples of speech recordings that illustrate comparisons between typical and disordered speech production across a broad range of disorder populations. Data of this type exist, but are typically collected for specific research projects under narrowly written IRB protocols that do not allow for release of even de-identified speech recordings to other investigators or teachers. As a partial corrective to …

The Effects Of Latent Infections And Atmospheric Pollutant Levels On Memory Search Reaction Times, Bowman Mccullough

Undergraduate Honors Theses

There are many regions where human population levels naturally create pollution by the processes by which everyday living occurs. This study views the effects on the reaction times of healthy individuals compared with individuals carrying latent infections Herpes Simplex 1, Toxoplasmosis Gondi, and Helicobacter Pylori, all residents of the Utah Valley region, known for poorer air quality due to the geographic landscape of the nearby mountains. College students were tested to see how high-pollutant air qualities (air pollutants PM 2.5 and PM 10 specifically) may have affected their reaction times when presented with stimuli from the Sternberg Memory Load and …

A Brief Overview Of Burst Suppression: Causes And Effects On Mortality In Critical Illness, Jake Hogan, Haoqi Sun, Hassan Aboul Nour, Stephen Piccolo, Jacob Crandall, Steven Peck, M Brandon Westover

Undergraduate Honors Theses

This thesis examines the effects of brain inactivation (burst suppression) on mortality in mechanically ventilated ICU patients. Past research has associated burst suppression with increased mortality. However, the effects of burst suppression on ICU patients while taking into account the relative contributions of propofol (a sedative), and critical illness to mortality, and whether preventing burst suppression might reduce mortality, has not yet been quantified. This thesis explores this relationship, and the effect of critical illness and propofol infusion on burst suppression to understand what drives burst suppression.

To measure the relationship between burst suppression, critical illness, propofol infusion, and mortality, …

Sunflower Seedlings Fail To Remove Uranium Pollution In The Navajo Nation: Participatory Science As A Path To Build Community And Address Environmental Injustice, Zak R. Webber

Undergraduate Honors Theses

Mid-20th century mining on Naabeehó Bináhásdzo (Navajo Nation) polluted groundwater with high concentrations of uranium and arsenic. The Navajo Nation and other rural residents of this region use groundwater for drinking, livestock, and irrigation. However, many individuals and communities must purchase and transport treated water from locations that are often hours away. Sunflowers have been shown to preferentially take up heavy metals, including uranium and arsenic, potentially representing a tool to improve water quality through on-site, low-cost phytoremediation. We carried out a collaborative research project with a high school class on the Navajo Nation in 2018 and 2019. The students …

Community Level Perspectives On Informal Alcohol: Understanding The Role Of Traditional Brewers In Dowa District, Malawi, Brian Allen, Jeff Glenn Dr.

Undergraduate Honors Theses

Alcohol consumption and consequential public health problems have recently increased in Sub-Saharan Africa and alcohol has been identified as the leading contributor to the burden of disease in the region. While Malawi has a relatively low overall alcohol consumption rate, the majority of the alcohol produced and consumed in the country is informal or unrecorded alcohol which present significant monitoring and regulatory challenges, in addition to greater health risks. This article explores the community level perspectives from traditional brewers of alcohol, and provides a comprehensive look into their experiences, perspectives, and the roles they play in their communities. In addition …

Staphylococcus Aureus Metal Acquisition In Milk And Mammary Gland Tissue, Shalee Killpack

Theses and Dissertations

Mastitis resulting from mammary gland infection is a common and painful disease associated with lactation. In addition to the impact on human and animal health, mastitis causes substantial economic losses in the dairy industry. Staphylococcus aureus is a frequent cause of mastitis worldwide. Despite significant progress in understanding S. aureus pathogenesis in general, much remains to be learned regarding virulence factors relevant in the context of mastitis. In mammary gland infections, it is not fully understood which metal acquisition systems are required for S. aureus survival. To help understand molecular mechanisms by which S. aureus might acquire essential metals, such …

Rising Action: The Effect Of Narrative Transportation On Consumer Purchase Behavior, Bryan Samuelsen

Undergraduate Honors Theses

We investigate whether narrative transportation can have an effect, not only on beliefs and purchase intentions, but on purchase behavior. Participants watch a video related to digital assistants and choose whether to enter a drawing for their choice of a digital assistant or a gift card; we hypothesize that those whose transportation is inhibited will be less likely to choose the digital assistant. We successfully inhibit transportation in the pretest, but do not see similar results in the study and are thus unable to determine if there is an effect on behavior.

Trends In Hospital Prices: Evidence From Hospital Chargemasters, Ulysse G. Mccann Iii

Undergraduate Honors Theses

In light of recent price transparency laws, this paper examines evidence from hospital list prices, contained on “chargemasters,” with regard to price trends over time, price variation between hospitals, and price variation between categories of goods and services provided by hospitals. I use data from California’s Office of Statewide Health Planning and Development (OSHPD) for 32 general acute care hospitals in Los Angeles County from 2011–2019. The data shows that the average list price for hospitals in the sample rises by about 3% annually. Prices between hospitals in the sample, which are similar in geography and the population served, vary …

Forgetting The Mine Wars: Erasing Insurrection In West Virginia History, Samuel Heywood

Undergraduate Honors Theses

This thesis examines the concerted effort in the West Virginia school system to forget a massive labor movement in the early 20^th century. Business leaders and government leaders turned to the classroom to try and control the memory of future generations to ensure a positive perception of the coal industry and avoid any more violent confrontations. After a brief summary of the Mine Wars for context, this thesis uses textbooks to analyze how the authors omitted the conflict and instead used patriotic propaganda to create loyal citizens. Although the Mine Wars have since been included in state history textbooks, …

School Nurses' Role During Disease Outbreak, Christina Rickenbach

Theses and Dissertations

Background and Purpose: School nurses have the critical task of overseeing the health and wellness of school-aged students. Utah is 1 of 17 states which allow parents to exempt their children from vaccines. The most common parental reason for exempting children from vaccines is personal choice. With the number of students without vaccinations on the rise, school nurses are tasked with responsibilities related to the spread of vaccine-preventable diseases. However, few studies have explored the role of school nurses in managing a disease outbreak. Therefore, the purpose of this study was to 1) explore the responsibilities of Utah school nurses …

An Analysis Of Opiate Prescription For Chronic Degenerative Disease And Other Pain Syndromes, Catherine Sawyer

Undergraduate Honors Theses

Utilizing the National Ambulatory Medical Care Survey (NAMCS) database, this thesis explores patterns of opiate prescribing during time period from 1993 to 2016, which includes the time period when the opiate crisis was recognized in the United States and efforts begun to combat it. We analyze these patterns particularly as they relate to patients who were prescribed opiates and who were simultaneously suffering from various chronic conditions, and interactions between prescription of opiates and diagnosis of chronic conditions. We examine which demographic groups were most likely to receive opiates, and considered opiate prescription trends among patients with any pain diagnosis …

Extending “Helping Babies Breathe” To An Academic Setting In Fiji, Ashley Langford

Student Works

Background: Approximately 2.5 million neonates died world-wide in 2018, with the majority dying in limited-resource countries. Over one-quarter of all neonatal deaths are caused by birth asphyxia, failure to breathe and maintain breathing after birth. To address the number of mostly preventable neonatal deaths due to birth asphyxia, Helping Babies Breathe (HBB) was created to teach basic neonatal resuscitation steps to health care workers in limited-resource settings. For this project, HBB training classes were held for faculty and nursing students at the Sangam College of Nursing in Labasa, Fiji.

Methods: Fifteen faculty members and 102 nursing students from the Sangam …

Species Composition And Hybridization Among Native And Nonnative Catostomid Fishes In Two Streams Of The Gunnison River Basin, Colorado, Michael R. Schwemm, Kevin G. Thompson, Evan W. Carson, Megan J. Osborne, Thomas F. Turner

Western North American Naturalist

We report results from a 3-year field investigation to limit hybridization between native and nonnative suckers in 2 small tributaries of the Gunnison River basin, Delta County, Colorado. Upstream movement to spawning habitat was selectively impeded by picket weir in intermittent Cottonwood Creek. There, native suckers were identified based on morphological characters in the field and were transferred upstream of the weir, whereas nonnative fishes were excluded from upstream movement. Another stream, Potter Creek, was not impeded by weir. Genetic identification of adult fishes in both streams was consistent with morphological identification in the field. Larval genetic identification was consistent …

Mirror, Mirror On The Wall: The Effect Of Listening To Body Positive Music On Implicit And Explicit Body Esteem, Sarah M. Coyne, Emilie J. Davis, Wayne Warburton, Laura Stockdale, Imogen Abba, Dean M. Busby

Faculty Publications

The current article used 3 studies to examine the impact of listening to body positive music on both explicit and implicit measures of body esteem in women. Study 1 found that women who viewed a mainstream popular body positive music video reported higher levels of body esteem than those who viewed a popular body objectifying music video. In Studies 2 and 3, we wrote and recorded our own songs to keep the musical features apart from the lyrics constant (e.g., rhythm, melody, and singer identity). Study 2 also found that women showed higher levels of implicit (but not explicit) body …

Becoming Faramir: Escapism As Responsibility And Hope Through Adaptation And J.R.R. Tolkien’S The Lord Of The Rings, Megan Kathryn Myers

Theses and Dissertations

When Peter Jackson sought to adapt J.R.R. Tolkien’s The Lord of the Rings to film, many fans worried about the changes that could be made to such a beloved story. Though the response to the films was generally positive, all three movies did have their detractors. Many of the complaints centered on his badly adapting the source material, specifically the characters. When Jackson released The Two Towers, fans were outraged further by how Jackson had handled Faramir. However, these interpretations of The Lord of the Rings and Faramir are a narrow evaluation of the larger problem facing fan and scholarly …
