Perceived Effects Of Open Textbook Usage On Secondary Science Classroom Practice, Stacie Lee Mason

Theses and Dissertations

Open Educational Resources (OER) provide openly licensed alternatives to commercial instructional materials. Proponents of K-12 OER suggest that their benefits include cost savings, increased access, improved quality, and increased teacher professionalism or empowerment. While the small body of K-12 OER research is growing, perceived benefits of K-12 OER usage have not yet been proven. The purpose of this qualitative study is to understand whether certain potential benefits were being realized by a group of secondary teachers using open science textbooks. In surveys and interviews, teachers were asked to describe their classroom practice before and after adopting an open textbook, including …

Effects Of Curcumin And Ursolic Acid On The Mitochondrial Coupling Efficiency And Hydrogen Peroxide Emission Of Intact Skeletal Myoblasts, Daniel J. Tueller

Theses and Dissertations

Curcumin is a natural compound that improves blood glucose management. While some evidence from isolated mitochondria indicates that curcumin uncouples electron transport from oxidative phosphorylation, the effects of curcumin on mitochondrial respiration and hydrogen peroxide emission in intact skeletal muscle cells are not known. By assessing rates of oxygen consumption, we demonstrated for the first time that curcumin (40 µM) reduced the mitochondrial coupling efficiency (percentage of oxygen consumption that supports ATP synthesis) of intact skeletal muscle cells. A 30-minute incubation with curcumin decreased mitochondrial coupling efficiency by 17.0 ± 0.4% relative to vehicle (p < 0.008). Curcumin also decreased the rate of hydrogen peroxide emission by 43 ± 13% compared to vehicle (p < 0.05). Analysis of cell respiration in the presence of curcumin revealed a 40 ± 4% increase in the rate of oxygen consumption upon curcumin administration (p < 0.05 compared to vehicle). In additional experiments, no difference in mitochondrial coupling efficiency was observed between vehicle- and curcumin-pretreated cells after permeabilization of cell membranes (p > 0.7). The possibility of synergistic …

Do Adults Diagnosed With Autism Spectrum Disorders Have An Advantage In Real-World Visual Search Tasks?, Nicholas Charles Russell

Theses and Dissertations

Individuals with Autistic Spectrum Disorders (ASD) often perform better than typically developing (TD) individuals in simple, albeit difficult, visual search tasks. This ability is often attributed to a lack of drive for coherence or superior local processing. We compare thirty adults with ASD with forty-nine TD individuals and twenty-seven adults with anxiety (ANX) across two real-world visual search tasks. Individuals had to find either a number superimposed over a real-world scene ("œno context" condition) or an object located in a contextually relevant location ("œcontext" condition). Each participant completed forty-one trials in each condition, each with a unique scene. Eye movements …

The Efficacy Of A Literature-Based Social Communication Intervention On Teacher Report Of Withdrawal For Children With Language Impairment, Cammy G. Peterson

Theses and Dissertations

Research shows that children with language impairment (LI) often have deficits in social communication. The purpose of this study was to examine the effectiveness of a social communication intervention targeting emotion understanding on teacher perceptions of withdrawal in six elementary-aged boys with LI. The intervention incorporated four elements into treatment sessions: a) Story sharing of children's literature that was rich in emotional content and prosocial behaviors; b) Story enactment of the same children's literature; c) identification and discussion of pictures of facial expressions; and d) journaling to help internalize and reflect on emotions and social behaviors targeted. Two withdrawal subscales …

Adapting Dracula: The Afterlives Of Stoker's Memes In Nosferatu (1922) And Dracula (1979), Ian Duncan Mcarthur

Theses and Dissertations

Dracula is a narrative that has risen above its own origins, having been translated and adapted across mediums it has inundated culture with vampires. However, with each adaptation the narrative and characters adapt into something new. This study is interested in the mechanism behind this evolution and argues that memes and, and their interpretations, are largely responsible for these shifts across adaptations. Three memes, in particular, tend to be adapted in films of Dracula. They include Dracula's appearance, Mina's empowerment, and the nature of the bite that they share. This analysis covers how these memes functioned in Stoker's original …

Sentence-Level Construction Methods: Skills Taught Are Skills Used, Susan Allsop Shelton

Theses and Dissertations

The findings of this study predict that students who utilize five specific sentence constructions on timed single-draft writing compositions will have higher holistic scores than students who do not utilize the specific constructions. Students in the treatment group who were taught to use the five constructions through thorough and consistent instruction in a semester length first year writing course showed statistically significant gains, 4.698 points on a 0-18 scale, based on comparison of pre-test and post-test writing samples. The findings suggest that specific style instruction at the sentence level should be part of the first year writing course curriculum, and …

"Goin' To Hell In A Handbasket": The Yeatsian Apocalypse And No Country For Old Men, Connor Race Davis

Theses and Dissertations

On its surface, Cormac McCarthy's No Country for Old Men appears to be a thoroughly grim and even fatalistic novel, but read in conjunction with W.B. Yeats' "The Second Coming"—a work with which the novel has a number of intertextual connection—it becomes clear that there is a distinct optimism at the heart of the novel. Approaching McCarthy's novel as an intertext with Yeats' poem illuminates an apparent critique of eschatological panic present in No Country for Old Men, provided mainly through Sheriff Bell's reflections on the state of society.

Role Of Terrestrial Organic Matter In Food Webs Of The Rocky Intertidal Zone, Douglas O. Fairbanks

Theses and Dissertations

Terrestrial organic matter (TOM) constitutes an important source of energy in many aquatic environments (streams, lakes, wetlands). This is the first study to examine the role of TOM in food webs of the rocky intertidal zone. We compared the consumption of red alder leaves (Alnus rubra) to common marine sources of drifting detritus along the southern Oregon coast (Nereocystis luetkeana, Phyllospadix spp., and Fucus gardneri). We used short term (hours to days) and long term (months) feeding experiments to compare the rate of consumption among each plant species during the Spring and Fall of 2014 …

The Relationship Between Auditory Habituation And Anxiety In Autism Spectrum Disorder, David Nicholas Top

Theses and Dissertations

Many individuals with autism spectrum disorder (ASD) have atypical sensory processing and behaviors including sensory sensitivity and low registration of sensory stimuli as well as sensory seeking and avoiding behaviors. Additionally, many individuals with ASD have clinically distressing levels of anxiety. Previous research suggests that there is a link between abnormal sensory processing, anxiety, and ASD. The purpose of this study was to experimentally observe auditory sensory processing using pupillometry methods, between ASD, control, and high-anxious control groups. While a difference in tonic pupil size was observed, there were no reactivity or habituation differences between the groups. There were no …

Religious Educator: Perspectives on the Restored Gospel

After hearing about the death of Frantiska “Mamousek” Brodilova, President John A. Widtsoe of the Quorum of the Twelve Apostles said, “Sister Brodil was a really marvelous woman. Her story must be preserved in Church history.” This paper preserves the memory of a woman whose faith and devotion to the truth and whose love for the Lord opened the door for an entire nation to receive the gospel of Jesus Christ. She was “a woman who prayed a mission into existence.”

Relationship Between Using Korean Folktales In Foreign Language Class And Learners' Reading Comprehension And Cultural Understanding, Eunsun You

Theses and Dissertations

Language is a reflection of society, so knowing about a language also means knowing about a culture. Therefore, many types of literature have been used as a language education tool representing culture. This thesis proposed folktales as an effective material of not only introducing culture but also learning language. Since folktales are old stories that have passed from generation to generation for a long time, values and morals of a culture are naturally presented in the context of the stories. Furthermore, folktales could enhance students' reading comprehension because the story lines, phrases, and words in a story are used repeatedly. …

Development Of An Early Expository Text Comprehension Assessment: A Pilot Study, Stacey Christianson

Theses and Dissertations

Literature supporting the use of informational texts with preschool children has increased in recent years. However, many preschool classrooms still focus on narrative text, and teachers are often unsure how to provide support for children's comprehension of informational texts. An assessment addressing preschool children's informational text comprehension will help teachers understand what children can do with informational texts and point out demands or tasks that children should be able to handle. A comprehension assessment for preschool children focusing on text purpose, text features, text retell, and comprehension of text structures has not been available. To fit this need, recent effort …

The Ability Of Five Children With Language Impairment To Describe Mental State In Story Narratives In Spontaneous And Prompted Conditions: Does It Help To Ask?, Naomi Asai

Theses and Dissertations

Numerous studies have shown that children identified with Language Impairment (LI) have marked difficulty with producing story narratives compared to their typically developing peers. One particular area of weakness seen in the narratives of children with LI is their ability to incorporate internal states, specifically internal response, internal plan, and emotion words. The current study examines five children with LI and their descriptions of mental and emotional states of characters in story narratives under spontaneous and prompted conditions. Participants produced story retells based on a series of wordless picture books taken from the Edmonton Narrative Norms Instrument. Story retells were …

Modulation Of Synaptic Plasticity: Endocannabinoids And Novel G-Protein Coupled Receptors Expression And Translational Effects In Interneurons, Katrina M. Hurst

Theses and Dissertations

Learning and memory are important processes that occur in the brain. The brain is comprised of neurons that make connections with each other known as synapses. Synaptic plasticity is widely believed to be the physiologic mechanism by which learning and memory occur. Synapses can either be strengthened through a process known as long-term potentiation (LTP) or weakened through long-term depression (LTD). The area of the brain that is most studied for its role in learning and memory is the hippocampus, which has been shown to be involved in memory consolidation. The detection of endocannabinoids and their receptors has opened a …

Function Of Ric-8a In G Protein E+- Subunit Biogenesis, Barry Willardson

Journal of Undergraduate Research

1. Grant Ludlam. The MEG award helped support Grant’s work from January 2015 through August 2016. During this time Grant has worked on three projects. He investigated the role of Ric8A in the folding of the G protein a subunit and its assembly into the G protein heterotrimeric complex. Unfortunately, his results showed that deletion of Ric8A in the photoreceptor cells of mice did not affect G protein signaling. As a result, he changed his research focus to determining the structure of the BBSome core complex. He assisted a graduate student, Takuma Aoba, in this work. They used a combination of …

Alzheimer’S Disease: A New Model Defining The Mechanism Of Iron- Catalyzed Radical Damage To Neurons, Richard Watt, Jonathan Wisco

Journal of Undergraduate Research

The MEG proposal focused on understanding how elevated homocysteine levels cause the inability of cells to control iron levels as a cause for Alzheimer’s disease. Iron is associated with the amyloid plaques and tau tangles that are proposed to cause damage to neurons. Dr. Wisco and I previously submitted an NIH R15 proposal that was viewed positively but was not funded due to a lack of preliminary data. Our goal was to use MEG funding to provide preliminary data supporting the hypothesis. We proposed that Homocysteine was a dangerous trigger for disrupting iron metabolism. Biochemical techniques, immunohistochemistry techniques and MRI …

Seasonal Progression Of Aquatic Organisms In A Temporary Wetland In Northern California, Michael G. Peterson, Kevin B. Lunde, Ming-Chih Chiu, Vincent H. Resh

Western North American Naturalist

Seasonal wetlands are important habitats for biodiversity of both invertebrate and vertebrate fauna. Many aquatic species have life history traits adapted to colonizing and developing in temporary aquatic habitats, and these traits influence the annual succession of the macroinvertebrate community. The chronology of taxon appearance and the variation in relative abundances during the hydroperiod are important for understanding population dynamics, trophic interactions, and responses to drought. This study investigated the successional changes in macroinvertebrate abundances in a seasonal wetland in northern California. Water quality parameters were measured regularly, including dissolved oxygen, temperature, pH, surface area, and specific conductance during the …

Rebuilding Kidneys, Alonzo D. Cook, Deverly L. Roeder, Jonathan J. Wisco

Journal of Undergraduate Research

The motivation for this work was the tremendous need for replacement kidneys. End-stage renal disease (ESRD) affects over 500,000 patients in the U.S. and costs Medicare $30 Billion annually for dialysis and transplant procedures. Our overall objective was to engineer kidneys from decellularized porcine extracellular matrix (DPECM) scaffolds and cell cultures grown from human progenitor cells. The primary reason for using human cells was to develop non-immunogenic kidneys that can be used to treat the more than 100,000 chronic kidney disease (CKD) patients awaiting a transplant, thus obviating the need for post-transplant immunosuppressive therapy and the associated risks of acute …

Avicenna’S Astrolabe, Peter Rich

Journal of Undergraduate Research

The goals of this project were to bring students from various disciplines across campus to create a digital game for beginning Arabic learners. The initial expectation of the project was to implement the game in an Arabic 101 classroom on BYU campus and evaluate it for further development. An initial conceptual prototype was evaluated in a summer Arabic course (Star Talk Arabic Language Camp). Due to changes in client expectations, an advanced prototype of the game was then created for online users. Dr. Rich worked with Matthew Bird, an IP&T doctoral student, who in turn mentored students in several disciplines …

Chronic Intermittent Ethanol To Establish Dependence, David Matthews, Scott Steffensen

Journal of Undergraduate Research

Excessive alcohol consumption in the United States is costing hundreds of billions of dollars in the United States alone. Addiction is a corrosive disease whose impact spreads across a broad spectrum including monetary damages, social disruption, health concerns, and life-ending decisions. Trailing a path of 88,000 alcohol-related deaths annually, government studies in 2006 reported that costs of excessive alcohol consumption reached $223.5 billion (Bouchery et al., 2011). In addition to monetary cost of alcohol abuse, the impact of this addiction can be devastating to personal and family life. Furthermore, addiction alters neural circuitry and becomes a self-absorbed behavior that robs …

Oxytocin And Infant Development: A Study Of The Genetic Underpinnings Behind Social Behavior In Rhesus Macaques, Spencer Waters, James Dee Higley

Journal of Undergraduate Research

It is widely accepted that the neuropeptide oxytocin helps mediate pro-social behavior and bonding between humans as well as other primates. Current genetic research has shown a link between variants in the oxytocin receptor gene (OXTR) and measures of social skills in humans. Demonstrating a link between oxytocin genotype and sociality, implies biological underpinnings for social bonding and affiliation in both human and nonhuman primates, suggesting that neurophysiological mechanisms may function to modulate a wide variety of social behaviors.

Effects Of Tetrabenazine On Basal Methamphetamine, Taylor Tribett, Scott Steffensen

Journal of Undergraduate Research

It is easy to see how much METH hurts the lives of its users and leads to high costs for society. Methamphetamine abuse is linked to higher healthcare costs, child abuse, and higher rates of theft and incarceration (Dobkin & Nicosia, 2009). Additionally, prescriptions for amphetamines (which are theorized to work by the same mechanisms) almost doubled in the United States between 2006 and 2011 (Sembower, Ertischek, Buchholtz, Dasgupta, & Schnoll, 2013). As the presence of these drugs becomes more widespread, the number of those at risk for abuse and addiction increases as well. In order to develop pharmacological treatments …

Habituation To Electronic Security Warnings, Corinne Devault, Brock Kirwan

Journal of Undergraduate Research

Habituation is the phenomenon that exhibits itself after repeated exposure to a stimulus; the brain response to it is decreased. This is seen in many different mediums, like tastes, touch, sound, etc., and thus could be observed in experiencing electronic security warnings as well. The brain needs constant vigilance when seeing warnings because large amount of personal information are saved on computers and other forms of technology. Ignoring a warning after it has appeared once or twice could result in a huge breach of information. Thus, it is important to study patterns of habituation of security warnings. There have been …

S-Glutathionylation Of Vmat By Acute Methamphetamine, Spencer Mccarthy, Scott Steffensen

Journal of Undergraduate Research

Methamphetamine (METH) has long been regarded as a potent addictive drug and psychostimulant. The addictive effects can be localized to the VTA, specifically activity of dopaminergic neurons in the nucleus accumbens (NAc). Overactivity of these neurons results in the pleasurable and addictive of METH. Various theories have been proposed as to the mechanism of this excess dopamine release; including a role for reactive oxygen species. In a recent publication, our lab has already demonstrated that METH induces the formation of reactive oxygen species (ROS) in the axon terminals of dopaminergic neurons in the nucleus accumbens and that blocking the formation …

The Effect Of Chronic Ethanol On Vta Gaba Neurons, Stephanie Bair, Scott Steffensen

Journal of Undergraduate Research

The current accepted model for addiction in the brain is the dysregulation of dopamine (DA) in the mesolimbic pathway, which begins in the ventral tegmental area (VTA) and projects to the nucleus accumbens (NAc). DA neurons originate in the VTA and project to the NAc where they release DA. Dopamine neurons are typically regulated locally by inhibitory gamma-aminobutyric acid (GABA) neurons in the VTA. Because GABA neurons in the VTA regulate DA neurons, we conclude that changes in VTA GABA neurons will affect DA release in the NAc underlying addictive behaviors, especially reward seeking.

The Role Of Nr4a1 In Β-Cell Glucose Stimulated Insulin Secretion And Cellular Survival, Kevin Garland, Jeffery Tessem

Journal of Undergraduate Research

In 2010, diabetes was the 7th leading cause of death in America, and as of 2014, 9% of the world’s adult population was affected by it. In both Type I (T1D) and Type II diabetes (T2D), a loss of β-cell mass and overall function is observed. β-cells essentially stop proliferating after adolescence, therefore developing mechanisms to increase function and/or induce proliferation in β-cells could serve as a powerful treatment and even a cure for both T1D and T2D. Overexpression of the β-cell transcription factor Nkx6.1 induces β-cell proliferation (1) and up-regulates expression of the nuclear receptor Nr4a1 (2). Nr4a1 has …
