Modeling Current And Future Windblown Utah Dust Events Using Cmaq 5.3.1, Zachary David Lawless

Theses and Dissertations

Windblown dust events can be defined as windblown dust emitted from the Earth's surface to the atmosphere. These events have significant impact on local air quality. Predicting the location and magnitude of these events is vital for Utah air quality assessment and planning. Previous modeling studies have focused only on past dust events. This work utilized a state-of-the-science software framework based on the Community Multiscale Air Quality (CMAQ) v5.3.1 modeling system to predict dust events in Utah. The framework was verified using previous studies for dust events in April 2017 and March 2010. Once verified, the framework was used to …

Increasing Introductory Biology Students' Modeling Mastery Through Visualizing Population Growth Models, Samantha Rae Wasson

Theses and Dissertations

In introductory biology, college students are taught to predict how populations will grow and change over time by using population growth models. These models are commonly represented as mathematical equations. However, students consistently struggle when math and biology concepts intersect in the classroom, and these struggles lead to suboptimal understanding of how mathematical population models are designed and used. Education literature suggests that students may struggle with population modeling because of math anxiety, the high cognitive load of the task, and the lack of scaffolding for abstract concepts. In our study, we sought to improve student mastery modeling exponential growth, …

The Music Of Rivers: How Climate, Land Use, And Disturbances Tune The Frequencies And Volumes Of Streams Worldwide, Brian Charles Brown

Theses and Dissertations

The amount of water flowing through streams and rivers changes through time. The seasonality and duration of these changes can have profound impacts on human freshwater availability, aquatic habitat, and biogeochemical cycling. Numerous factors are thought to influence streamflow regime, including drainage basin area, temperature, precipitation, and land cover. Few of these qualities have remained untouched, either directly or indirectly, by expanding human activities. Altered climate, sweeping changes to large portions of the earth's surface, and the construction of dams and other infrastructure have fundamentally altered streamflows worldwide. Understanding the nature of these changes, both globally and regionally in the …

Stress-Induced Plasma Cortisol Concentrations In Infancy Are Associated With Later Parenting Behaviors In Female Rhesus Macaques (Macaca Mulatta), Colt Halter

Undergraduate Honors Theses

Few studies have longitudinally assessed the relationship between infant stress reactivity and future parenting styles. Stress-induced plasma cortisol concentrations are stable over development and can be utilized as a marker for stress reactivity. This study investigates the relationship between stress-induced plasma cortisol concentrations in infancy and later parenting behavior in a translational nonhuman primate model. We hypothesized that higher stress-induced cortisol levels in infancy would predict impairments in maternal behaviors in adulthood. Subjects were rhesus macaque females (N=122; Macaca mulatta), assessed as infants and again as mothers. At three-to-four months of age, subjects underwent a standardized BioBehavioral …

Methods To Stop Caffeine Use And Minimize Caffeine Withdrawal Symptoms In The State Of Caffeine Dependence: A Literature Review, Morgan Behling, Blaine Winters

Student Works

Caffeine is the most consumed psychoactive drug in the world and those who consume it frequently become dependent. Even if individuals desire to quit caffeine, they may not be able to due to withdrawal side effects, or a lack of knowledge of how to quit. Harmful effects of long-term caffeine consumption include fatigue, irritability, headaches, nausea, and depression. The goal of this literature review was to explore current evidence on different methods to quit or reduce caffeine use and minimize caffeine withdrawal effects in those who are dependent. A literature review of studies from 2014 to 2020 was conducted using …

A Comparison Of Heat Treatment-Induced Skeletal Muscle Adaptations Relative To Exercise Training, Jamie Puanani Brun Kaluhiokalani

Theses and Dissertations

In vitro and animal studies indicate that the response to heat stress is associated with beneficial adaptations that promote cell health and survival. Few studies to date have examined this finding in human subjects, and it is unclear how the adaptation compares in magnitude to exercise training. The purpose of this study was to investigate the skeletal muscle adaptations (namely mitochondrial biogenesis and capillarization) of 6 weeks of deep-muscle heat treatment relative to exercise training. We hypothesized that heat treatment (HT), applied through pulsed shortwave diathermy (2 hr, 3 days/week) over a 6-week intervention period would lead to increased mitochondrial …

Understanding The Interaction Between Habitat Use Of Feral Horses And The Abundance Of Greater Sage-Grouse In The Great Basin, Mikiah R. Carver

Theses and Dissertations

Environmental impacts of feral horses (Equus caballus) are a subject of conservation concern and controversial national policy. In North America, feral horses are considered an invasive species where they impact rangelands of the arid and semi-arid western United States. The greater sage-grouse (Centrocercus urophasianus) is a native sagebrush obligate bird species that relies on sagebrush habitats to sustain viable population levels. Recent literature suggests that feral horse presence can have a notable effect on the fitness of native and sagebrush obligate species throughout the arid and semi-arid western United States. The purpose of this thesis was to assess the potential …

Pinpointing Pornography's Effects: Paring Off The Influences Of Masturbation, Sexual Desire Discrepancy, And Sexual Engagement In Heterosexual Dyads, Brady C. Eisert

Theses and Dissertations

Pornography has increasingly become a hot topic of discussion in the United States, likely due to its increasing rate of consumption. Recent scholarship has indicated the need to account for factors such as masturbation and sexual desire discrepancy when conducting pornography research. The current study isolated the influence pornography use had on those in heterosexual romantic relationships (N=713 couples) by parsing out the effects of sexual desire discrepancy and masturbation. This was done by using a series of nested actor-partner interdependence models (APIM) to see how the relationships between pornography use and sexual satisfaction changed in each model. Masturbation and …

Camera Traps Provide Insights Into American Pika Site Occupancy, Behavior, Thermal Relations, And Associated Wildlife Diversity, Constance I. Millar, Kenneth T. Hickman

Western North American Naturalist

Custom camera traps were positioned at American pika (Ochotona princeps) haypiles in 12 warm, low-elevation locations of eastern California over 5 years and during warm and cold seasons. These camera traps detected 26 mammal and 10 bird species, including 4331 pika events as well as visits by 16 sympatric herbivores and 7 pika predators. Camera traps documented pika occupancy at some sites that had been evaluated from field surveys as extirpated, and they also confirmed field assessments of extirpation at other sites. Individual pikas could be distinguished by scars, size, and pelage diagnostics, allowing animals to be followed …

Southwestern Bats And Their External Bacteria, Ernest W. Valdez, Emily M. Johnson, Edward W. Strach, Patrick A. Lewis, William C. Briggs, Nicole A. Caimi, Ara S. Winter, Jennifer J.M. Hathaway, Diana E. Northup

Western North American Naturalist

Bat species diversity within the United States is greatest in the Southwest, with approximately 30 species present. At least 16 of these bat species hibernate and are susceptible to white-nose syndrome (WNS), which is caused by the fungus Pseudogymnoascus destructans. Since 2006, millions of bats from 35 U.S. states and 7 Canadian provinces have died from WNS. In previous studies of external surfaces of bats sampled from southwestern states, Actinobacteria were detected that were shown to have antifungal properties against P. destructans in laboratory testing. These studies motivated us to expand our research to sites that represent possible gateways …

Detecting Remnants Of The Past: Archaeo-Geophysical Prospection Of Fremont Sites In Southern Utah Valley, Jacob P. Jepsen

Theses and Dissertations

The variable contexts of Fremont habitation sites in Utah Valley often make identification of those sites very challenging for archaeologists. Pit houses and other structures throughout the valley are frequently in plowed fields or other disturbed contexts that obscure their more exact location and nature. The application of geophysical technologies at archaeological sites throughout the world, including in North America, has proven to be an effective means of subsurface archaeological survey. However, geophysical techniques have been underutilized in Fremont archaeology. This paper reports on the employment of two geophysical methods, ground-penetrating radar (GPR) and fluxgate gradiometer surveys, at three known …

Fisher Use Of Postfire Landscapes: Implications For Habitat Connectivity And Restoration, Craig Thompson, Heath Smith, Rebecca Green, Sam Wasser, Kathryn Purcell

Western North American Naturalist

The relationship between fishers (Pekania pennanti), fire, and fuel management in the Sierra Nevada region is complex and highly controversial, and the recent listing of southern Sierra Nevada fishers as endangered has brought this issue to the forefront for many land managers. While wildfire is a natural component of the historic disturbance regime in the dry, mixed conifer forests of California, it also has the capacity to destroy large swaths of suitable habitat and to fragment tenuous populations, particularly given recent shifts in wildfire scope and severity. Therefore, balancing fuel reduction with habitat conservation requires careful consideration of …

Each Atom An Agent?, Steven L. Peck

BYU Studies

An agent, broadly conceived, references something causally efficacious. More narrowly, the word agent is usually deployed in at least three senses. The first is as brute causality. For example, to say that water is an agent of erosion on vegetatively barren hillsides is to claim that water directly causes the removal of the soil in particular drainage systems. The second sense, used predominately in biology, recognizes an agent as an individual autonomous system that constrains the flow of energy and matter such that its actions are performed for particular functions or goals. For instance, a simple bacterium is drawn to …

Christ As Our Law: He Who Sanctifies, Enlightens, And Saves, Keith Lane

Religious Educator: Perspectives on the Restored Gospel

The doctrine of Christ is a living, practical theology of discipleship (see 2 Nephi 31:21, Doctrine and Covenants 10:62). With the revelations given to Joseph Smith, particularly those in the Doctrine and Covenants, the faith of the Latter-day Saints is grounded in the realm of practical behavior— of religious life ordered for individuals and the Church by laws, principles, and, above all, covenants and ordinances given us by Deity. But all these point to Christ himself as the law. Clearly there are elements of correct belief or orthodoxy, but these are primarily useful because they point us to faith in …

Section 77 And Book Of Revelation Scholarship, Nicholas J. Frederick

Religious Educator: Perspectives on the Restored Gospel

The book of Revelation is a complicated book, to say the least. For those of us who teach courses covering the book of Revelation, we often rely upon Joseph Smith’s questions and answers on the book of Revelation, now canonized as Doctrine and Covenants 77, as a means of providing some answers to all the mysterious complexity John’s vision presents to us. However, the question inevitably arises as to how closely the answers provided in section 77 adhere to the text of the book of Revelation as well as the opinion of New Testament scholars, both those contemporary to Joseph …

Influencing Perceptions Of Stem Through The Best Stem Books List, Scott Bartholomew, Alexia Seymour

Faculty Publications

One day, while discussing engineering and science as potential career options with a female student, we opened a search engine and typed in “engineer” and “scientist.” However, on the first pages of image results, only one female appeared for engineering and only a few females appeared for “scientist” (see Figure 1). This disparity was disturbing—if this student never saw another person like her filling careers in STEM fields, would she ever “picture herself” in those fields?

Cultivating Internal Rhetoric: Lessons On Self-Directed Rhetoric From Protestant Meditation Manuals And Modern Metacognitive Theory, Jared Vanhille

Theses and Dissertations

Internal rhetoric describes how individuals engage in self-persuasion. Jean Nienkamp developed a theory of internal rhetoric by drawing on both the rhetorical tradition and the field of psychology. I build on Nienkamp's work by arguing that the Christian meditative practice outlined by Joseph Hall in The Arte of Divine Meditation (1607) and Edmund Calamy in The Art of Divine Meditation (1634) provides a theoretical and practical framework for performing a particular kind of internal rhetoric in which people become the rhetorical critic by reading their own beliefs and knowledge and then become the rhetor by composing self-directed arguments. This process …

< Justice > And < Open Debate >: An Ideographic Analysis Of < Freedom Of Speech >, Emily Ann Spackman

Theses and Dissertations

< Freedom of speech > is a foundational ideograph in the American and more broadly, Western, tradition. Yet this term is not static in its meanings or commitments to social action. The current debate around cancel culture is the site of renegotiation of < freedom of speech > in relation to other terms such as < open debate >, < justice >, < marginalized >, < tolerance >, < democracy >, and < power >. This study is an ideographic analysis of two artifacts that represent two sides of the < freedom of speech > discussion: “A Letter on Justice and Open Debate” and “A More Specific Letter on Justice and Open Debate.” Following McGee’s theory and method, this research examines the diachronic definition of < freedom of speech > through the U. …

The Impact Of Emergency Response Trainees During The Ebola Outbreak In Sierra Leone, 2014-2016, Abbey Whitcomb

Undergraduate Honors Theses

This research aimed to address the impact of non-health trainees as a part of the emergency health response during the Ebola outbreak within Sierra Leone. The non-health trainees, including sanitation workers within health settings, ambulance drivers, burial teams, prison officers, community engagement staff, border officers, traditional birth assistants, etc. was contrasted with individuals receiving clinical and patient-care training. The data were taken from weekly situation reports published by the Internal Organization for Migration in 2015. Using a negative binomial model, we sought to determine the incidence rate ratio of weekly cases and deaths as a result of new trainees. Trainees …

Changes In An Exotic Fish Community Assemblage Of A Thermal Spring In Central Idaho, Skyler Smith, Bart Gamett, Ryan Beatty, Eric Billman

Western North American Naturalist

Barney Hot Springs is a thermal spring in the headwaters of the Little Lost River drainage in central Idaho. Tropical fish have been released into Barney Hot Springs, and several species have established self-sustaining populations. The objectives of this study were to determine the current community assemblage of tropical fish in Barney Hot Springs and to assess species composition and extent of downstream distribution of tropical fish in Barney Creek. The composition in 2017 consisted of Amelanic Convict Cichlids Amatitlania nigrofasciata, Mozambique Tilapia Oreochromis mossambicus, Zebra Mbuna Maylandia zebra, and Green Swordtails Xiphophorus hellerii. Total abundance …

Localized Anthropogenic And Geogenic Groundwater Contamination In The Structurally Complex Carbonate-Hosted East Tintic Mining District, Eureka, Ut, Usa, Cameron Patrick Cordner

Theses and Dissertations

Legacy mining areas throughout the world contain widespread contaminated surface and groundwater from both anthropogenic and geogenic sources. Abandoned mine waste can contribute harmful solutes to groundwater and surface water, as metals mobilize through oxidation of sulfide minerals. Geogenic contaminant sources, such as geothermal water and mineralization, may also contribute to groundwater pollution in mining areas. To investigate the relationship between various groundwater contamination sources in legacy mining areas we sampled ~30 cold springs in the East Tintic Mountains of Utah and 8 regional hot springs as a proxy for geothermal water during fall 2019 and spring/summer 2020. Water chemistry …

What North American Bees Are Associated With Milkweed (Asclepias) Flowers?, Joseph S. Wilson

Western North American Naturalist

Recent interest in protecting pollinators has led many organizations to plant milkweed to support monarch butterflies. However, little is known about what bee species might also benefit from milkweed plantings. Here I compile a list of bee species that have been collected on milkweed flowers. I compiled these data by searching large online databases and regional collections and supplementing with field collections. At least 282 different bee species have been collected on milkweed. Milkweed flowers can provide an important nectar resource for foraging bees, particularly in arid regions and in dry times of the year.

Landscapes Of Medical Culture From The Amazonia Of Ecuador, Savannah Sorensen

Undergraduate Honors Theses

This thesis examines the relationships between humans and plants in the Ecuadorian Amazon and the role relationships and nature play in the affliction and healing of illnesses and diseases. Through animism, spirituality, and rituals, the Quechua and Canelos groups foster a deep connection with the land and each other which plays an important role in traditional medicine and healing; this important connection with each other and the land constitutes the main premise of this paper, the sociality of healing. Many other cultures such as the Kalahari Kang, Samoans suffering from cardiovascular problems, and Evangelical Christians take on a similar approach …

Parent Perceptions Of Literacy Development For Females Later Diagnosed With Autism Spectrum Disorder, Christine Marie Yaccarino

Theses and Dissertations

Little is known about the early literacy development of girls later diagnosed with autism spectrum disorder (ASD) or autism traits. In this study, parents of 21 girls later diagnosed with ASD or as having significant ASD traits were each interviewed about their daughter's early literacy development. In general, findings indicated that parents reported their daughters' early success with word level reading. Initially, parents conflated that one area of reading success to also indicate an overall accomplishment in broad reading skills. Findings also indicated that parents simultaneously acknowledged successful word level reading, yet over time noted specific challenges in early literacy …

Abundance And Activity Of Domestic And Wild Medium-Sized Mammals In A Protected Mangrove Remnant, Puerto Vallarta, Mexico, Beatriz F. García-Padilla, Sylvia S. Zalapa, Sergio Guerrero-Vázquez, Alejandro Pérez-Arteaga, Agustín Camacho-Rodríguez

Western North American Naturalist

Domestic dogs (Canis lupus familiaris) and cats (Felis catus) in natural reserves can affect wild mammal populations through predation, diseases, and disturbance, particularly when habitat patches are small. In Estero El Salado, a remnant mangrove in Puerto Vallarta, Mexico, we used camera trapping to obtain independent observations (n = 1224) to determine abundance, spatial overlap, and activity of medium-sized mammals (domestic dog, domestic cat, northern raccoon [Procyon lotor], Virginia opossum [Didelphis virginiana], gray fox [Urocyon cinereoargenteus], ninebanded armadillo [Dasypus novemcinctus], and jaguarundi [Herpailurus yagouaroundi]). Our …

Musical “Conquest”: The Spanish Use Of Music In The Spiritual Conquest Of The Nahua Peoples Of Sixteenth-Century Mexico, John Richardson

Undergraduate Honors Theses

Historians have grown more interested in Spanish Conquest and colonialism in the last century. While earlier historians saw the conquest through a more euro-centric lens, recent historians have tried to take a more nuanced approach to understanding the conquest. Within this research, historians are questioning traditional narratives of the "spiritual conquest," or the conversion of native peoples to Christianity. Scholars have shown that "conquest" is not the best term for this process, as there was much more give and take at play.

My research seeks to strengthen this narrative of religious accommodation through the lens of music. The transmission of …
