Material Characterization Using Nuclear Magnetic Resonance, Giovanna Marcella Pope

Theses and Dissertations

Nuclear magnetic resonance techniques can provide highly accurate information about the local environment of both liquid and solid samples. In the first half of this dissertation research, solid state NMR has provided experimental evidence for turbostratic disorder in layered covalent organic solids. Additionally, comparison with candidate structures allowed a proposed correction to the accepted structure of Covalent Organic Framework-5. The second half of the dissertation work emphasized liquid NMR spectroscopy applied to doped iron oxides (IOs). In particular, the effect of IOs on water proton T2 relaxation times were determined as a measure of contrast agent efficacy. Both types of …

Flowering By Dioecious Rhamnus Ilicifolia (Rhamnaceae) And Pollen Transport To Female Flowers By Flies And Bees, William D. Wiesenborn

Western North American Naturalist

Rhamnus ilicifolia (Rhamnaceae) is a large shrub found in a range of habitats from southern Oregon south to Baja California and east into Arizona. During spring, the plant produces clusters of unisexual flowers, each with a 5–6-mm-diameter, open perianth of green or yellowish-green sepals. I investigated the pollination of R. ilicifolia in western Arizona during 27 April to 21 May 2020 by examining the distribution and phenology of male and female flowers on shrubs, collecting insects from female flowers, and determining the proportions of conspecific pollen on insects to estimate floral constancy. Shrubs were dioecious, and individual male and female …

Decline Of The Northern Long-Eared Myotis (Myotis Septentrionalis) In The Eastern Great Plains After The Arrival Of White-Nose Syndrome, Jeremy A. White, Patricia W. Freeman, Madelene I. Shehan, Cliff A. Lemen

Western North American Naturalist

The northern long-eared myotis (Myotis septentrionalis) has declined sharply in the eastern United States due to the disease white-nose syndrome (WNS), which is caused by the fungus Pseudogymnoascus destructans (Pd). However, less is known about the species’ status in the central and western parts of its range where WNS has arrived more recently. Here we report the timing of the arrival of Pd and WNS to eastern Nebraska and examine acoustic and capture data of M. septentrionalis to determine the initial impact of the disease on this species. We sampled bats for the presence of Pd …

Stent Retriever Versus Direct Aspiration Thrombectomy For Acute Large Vessel Occlusion: A Meta-Analysis Including 17,556 Patients, From Mr Clean To Present, Eric R. Smith, Jacob A. Bethel, Timothy B. Smith, Grant Holden, Furkan Torlak, Matthew Grimsbo, Ali Seifi, Justin R. Mascitelli

Faculty Publications

Objective

Stent retriever (SR) and direct aspiration (DA) mechanical thrombectomy (MT) improve clinical outcomes for stroke secondary to large vessel occlusion. The purpose is to perform an updated meta-analysis comparing the two techniques.

Methods

PubMed database was searched for studies between January 1, 2015, and July 5th, 2021 with mechanical thrombectomy to treat acute ischemic stroke.

Results

We identified 136 studies including 17,556 patients, with 11,258 (64.1%) patients treated by SR or a combined approach and 6298 (35.9%) patients with DA. The DA group had less posterior cerebral artery strokes, was significantly older, and had lower National Institutes …

A Proposal For Paid Family Leave In Utah, Erin Wong

Student Works

When a woman gives birth, the arrival of that child will have a statistically significant negative impact on that woman’s employment, earning potential, health, and overall wellbeing. The arrival of a child has no statistically significant impact on men’s employment, earning potential, or overall health and wellbeing. The labor force experiences a drain of talent and productivity when mothers leave the market in large numbers after having a child. Many mothers who wish to remain the workforce after childbirth are faced with the impossible choice of their child’s health or their own job and earning potential. Many fathers or partners …

Cytogenetics Of Black Fly Larvae (Diptera: Simuliidae) From The Logan River, Utah, The Type Locality Of Simulium Brevicercum, Gerald F. Shields

Western North American Naturalist

I analyzed 221 black fly larvae of the Simulium arcticum complex from the Logan River, Logan Canyon, Utah, for larval sexual dimorphism, chromosomal inversions, morphology of the centromere band of chromosome IIL, presence of B chromosomes, and frequency of the IS-1 autosomal polymorphism. All 2275 larvae collected at the Logan River were of the S. arcticum complex with one exception, which was S. canadense. I found a significant association between larval color and sex, but I did not find such an association between larval head patterns and sex. Nearly all chromosomally analyzed larvae had standard, noninverted IIL chromosomes in …

Variation In Trophic Niches Of Fish In Lake Powell Prior To Full Colonization By Quagga Mussel (Dreissena Rostriformis Bugensis), Joshua A. Verde, Nathan R. St. Andre, Mark C. Belk

Western North American Naturalist

Invasive species can cause disruption of the trophic niche of resident species such that patterns of energy flow through ecological systems are altered. Quagga mussel Dreissena rostriformis bugensis Andrusov, 1897, a notorious invasive species, was introduced to Lake Powell (Utah and Arizona, USA) in 2012 and colonized the entire reservoir by 2017. To help understand potential effects of this invasive species on the trophic niche of fishes in Lake Powell, we characterized trophic niche of fishes and other organisms, as well as sources of variation in trophic niche, using stable isotope analysis of carbon and nitrogen prior to full colonization …

Early Records Suggest A Broader Historic Range Of The Ozark Big-Eared Bat (Corynorhinus Townsendii Ingens), D. Blake Sasse

Western North American Naturalist

The endangered Ozark big-eared bat (Corynorhinus townsendii ingens) is currently found in northcentral and northwestern Arkansas and northeastern Oklahoma. Although historically known to be present in 2 counties on the southwestern border of Missouri, this species has not been observed in Missouri since 1971. A female Ozark big-eared bat specimen in the museum collection of Harvard University was reportedly collected in Arkansas, possibly in 1858. An investigation of the documentation associated with this and other specimens collected by the same individual suggests that this Ozark big-eared bat may have been collected on the Osage River in west-central Missouri …

Optimization Of A Smart Sensor Wearable Knee Sleeve For Measuring Skin Strain To Determine Joint Biomechanics, David Steven Wood

Theses and Dissertations

This work addresses three objectives related to the design and modeling of an instrumented knee sleeve and its high deflection strain gauges for at-home knee rehabilitation. First, a multi-objective Bayesian approach was developed to economically optimize a high deflection strain gauge's mechanical and electrical behavior. Four objective functions were simultaneously optimized with two design variables in seven iterations; 90% faster than a grid search approach. The presented algorithm adjusts variables in the manufacturing process of high deflection strain gauges and produces a sensor with optimized properties for a predetermined purpose. Second, an algorithm was created to accurately approximate the dynamic …

The Power Of Human Connection: Autism And The Suicide Risk, Rachel Barton

Intuition: The BYU Undergraduate Journal of Psychology

As researchers continue to understand autism spectrum disorder (ASD), one outstanding factor is causing concern within the psychological community: those with ASD are at a much higher risk of suicidal tendencies. These tendencies include suicidal ideation, attempting suicide, and death by suicide. Possible contributing factors to this increased risk include high levels of loneliness, pressure to conform to societal norms, as well as depression and anxiety. To decrease suicidality among the ASD population, further research is needed to fully understand why this behavior occurs at such a high percentage. Research is also needed to find appropriate and effective solutions to …

Reducing College Student Burnout: Predictive Factors, Harmful Effects, And Preventative Strategies, Eden Semu

Intuition: The BYU Undergraduate Journal of Psychology

Academic burnout is defined as experiencing emotional exhaustion, having cynical attitudes toward other people and one’s studies, and feeling unable to achieve one’s academic goals (Schaufeli et al., 2002b). Academic burnout has been observed among college student populations, and its prevalence is increasing as college students are more susceptible to psychological illness, are experiencing peak levels of life stress between ages 18 and 33, and are learning to handle novel demands associated with emerging adulthood (APA, 2012; NAMI , 2019). Internal factors, such as motivational style, attitude, and coping mechanisms, have been shown to mediate the relationship between demands and …

Infant Language Development: The Consequences Of Trauma, Janna Pickett

Intuition: The BYU Undergraduate Journal of Psychology

Infants between 0 and 36 months who experience physical and emotional trauma are at risk for severe social, emotional, cognitive, and physiological developmental deficits (Carpenter & Stacks, 2009; Jacobsen et al., 2013). As researchers search for protective factors against these deficits, productive language acquisition (the words an infant can verbally produce) has emerged as a potential predictor of resilience (Bellagamba et al., 2014; McCabe & Meller, 2004). This review proposes that infants who have acquired more advanced language, such as emotion descriptors, are able to define their experiences, learn how to respond to those experiences, and feel in control of …

The Double-Edged Sword: Unsuccessful Versus Successful Religious Parenting And Transmission, Avanlee Peterson

Intuition: The BYU Undergraduate Journal of Psychology

Religious participation can have many positive effects on children and adolescents, including improved health, academic, and social capabilities. Therefore, many parents are concerned by the decrease in religiosity in American society today. In response to this common concern, this literature review discusses how various types of religious parenting can improve parent-child religious transmission while maintaining good parent-child relationships and promoting healthy child development. Much of the research on parenting styles suggests that religious parenting is most successful when using an authoritative style of parenting (high structure, high warmth, high autonomy) rather than an authoritarian style (high structure, low warmth, low …

Postseptic Cognitive Impairment And Expression Of Apoe In Peripheral Blood: The Cognition After Sepsis (Cass) Observational Pilot Study, Samuel M. Brown, Sarah J. Beesley, Chris Stubben, Emily L. Wilson, Angela P. Presson, Colin Grissom, Colin Maguire, Matthew T. Rondina, Ramona O. Hopkins

Faculty Publications

Background: Cognitive impairment after sepsis is an important clinical problem. Determinants of postseptic cognitive impairment are not well understood. We thus undertook a systems biology approach to exploring a possible role for apolipoprotein E (APOE) in postseptic cognitive impairment.

Design: Prospective, observational cohort. Setting: Intermountain Medical Center, a tertiary referral center in Utah.

Patients/Participants: Patients with sepsis admitted to study intensive care units. Interventions: None.

Methods: We obtained peripheral blood for deep sequencing of RNA and followed up survivors at 6 months with a battery of cognitive instruments. We defined cognitive impairment based on the 6-month Hayling test of executive …

Education Abroad For Students With Disabilities: Legal Implications, Heidi Fischer

BYU Education & Law Journal

Prior to the COVID-19 pandemic, United States (U.S.) student participation in education abroad (EA) programs increased by more than thirty percent over a ten-year span.1 During the 2018-19 academic year, more than 36,000 students studying abroad identified as students with disabilities (nearly ten percent).2 The steady rise in U.S. student participation in EA programs in the past decade not only suggests renewed post-pandemic growth, but it also supports the idea that greater quantities of students with disabilities will study abroad during their postsecondary education than in previous years. With nearly one in five undergraduate students identifying as having a dis-ability,3 …

Lehi And Nephi As Trained Manassite Scribes, Noel B. Reynolds

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

This paper brings together contemporary Ancient Near East scholarship in several fields to construct an updated starting point for interpretation of the teachings of the Book of Mormon. It assembles findings from studies of ancient scribal culture, historical linguistics and epigraphy, Hebrew rhetoric, and the history and archaeology of Mesopotamia, Egypt, and the Levant, together with the traditions of ancient Israel to construct a contextualized perspective for understanding Lehi, Nephi, and their scribal training as they would have been understood by their contemporaries. Lehi and Nephi are shown to be the beneficiaries of the most advanced scribal training available in …

The Body As The Temple Of God, Lareina Hingson

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

Metaphors occur when there is a contradiction in the senses of the words used that cause the text to be interpreted non-literally, as Paul Ricoeur has noted. The Apostle Paul’s letter to the Corinthians describing the body as a temple has been taken to be one such scriptural metaphor: “Know ye not that ye are the temple of God, and that the Spirit of God dwelleth in you? … know ye not that your body is the temple of the Holy Ghost which is in you?” (1 Corinthians 3:16; 6:19). As a metaphor, it is a strong one. The supposed …

An Unexpected Case For An Anthropomorphic God, Daniel C. Peterson

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

Given the knowledge of the corporeal, embodied nature of God that the Prophet Joseph Smith received in his 1820 First Vision, Latter-day Saints have argued from their earliest days that the Bible is most accurately understood as teaching precisely the same thing — that God has a body and that humans are literally created in his physical image. Now, a new book from an unlikely (and quite unintentional) ally makes a strong case for our position. It is a book that will both gratify Latter-day Saints and, at some points, offend them. In any event, readers of Interpreter should be …

Alma’S Prophetic Commissioning Type Scene, Alan Goff

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

The story often referred to as Alma’s conversion narrative is too often interpreted as a simplistic plagiarism of Paul’s conversion-to- Christianity story in the book of Acts. Both the New and Old Testaments appropriate an ancient narrative genre called the prophetic commissioning story. Paul’s and Alma’s commissioning narratives hearken back to this literary genre, and to refer to either as pilfered is to misunderstand not just these individual narratives but the larger approach Hebraic writers used in composing biblical and Book of Mormon narrative. To the modern mind the similarity in stories triggers explanations involving plagiarism and theft from earlier …

The Queer Philosophies Of Men Mingled With Scripture, Daniel Ortner

Interpreter: A Journal of Latter-day Saint Faith and Scholarship

Blaire Ostler attempts to show how “Mormon theology is inherently queer” and may be expanded to be fully “inclusive” of LGBTQ+ members. Unfortunately, Ostler conflates God’s love with indulgence for behavior that he has described as sinful. She offers a pantheistic/panentheistic conception of deity that collapses any differences between men and women in sharp contrast to the Latter-day Saint understanding that men and women are complementary and require one another for exaltation and eternal life. Many of this book’s arguments are sophistry and the philosophies of men mingled with scripture. None of it is compatible with revealed truth contained in …

The Developing Global Crisis And Survival Of Human Civilizations, Michael M. Andregg Ph.D.

Comparative Civilizations Review

For over thirty years, we have used a phrase “the Developing Global Crisis” to identify a cluster of recurring causal factors of chaos that are especially difficult to deal with. These are: population pressure (not simply growth), corruptions of governance (hard to study in democracies much less in police-states), authoritarian political systems, and militant religions. The West has failed to control these recurring causes of chaos, often by imperial patterns of behavior instead of more enlightened governance. Civilizational scholars in Japan might be able to find better solutions to these problems for Asia and the world if they try hard. …

The Russian Sphinx: Contemplating Danilevsky’S Enigmatic Magnum Opus Russia And Europe, Vlad Alalykin-Izvekov

Comparative Civilizations Review

The relations between Russia and the West have never been particularly easygoing or unambiguous, and, presently, they are yet again at an all-time low. The way to better understand, as well as to successfully communicate and cooperate with another society is through learning about evolution (and revolutions) of their (as well as one’s own) history and culture. Are there any important sources in the Russian cultural heritage that could illuminate these ages-old problems, tendencies, and trends? The year 2021 marks 150 years since publication of Nikolay Danilevsky's book Russia and Europe (1871), while the next one, the year 2022, denotes …

The Architecture Of The Universe: A Look Into Extraterrestrial Civilizations, Andrew Targowski

Comparative Civilizations Review

The article advances a synthesized view of the world based on an intelligently communicated undivided Universe. It presents a fundamental component-based architecture and characterizes the controlling role of info-communication processes in the interplanetary system. The Fermi Paradox is then considered, which leads to a discussion about the concept of God as it pertains to Albert Einstein’s and Stephen Hawking’s theories. The article next introduces the author’s own understanding of God. The approach adopted in this study situates Earth’s civilization within the broader context of extraterrestrial civilizations, and it considers what this means for modern humans. Further research is also suggested …

The Orchid And The Missile, Paul Alan Cox

BYU Studies

The MX missile program was proposed by the United States as a response to a perceived missile gap with the Soviet Union in the late 1970s. The basing mode, consisting of multiple silos between which a single launch vehicle would be shuttled, would have consumed large portions of western Utah and eastern Nevada. Although touted as a counterforce weapon, the extraordinary accuracy of the MX would have resulted in the USA constructing an invisible first strike system, destabilizing the strategic balance. Stopping or even slowing the MX deployment seemed impossible before two unexpected events occurred: explicit opposition to the MX …
