Developing The Definite Integral And Accumulation Function Through Adding Up Pieces: A Hypothetical Learning Trajectory, Brinley Nichole Stevens Jun 2021

Developing The Definite Integral And Accumulation Function Through Adding Up Pieces: A Hypothetical Learning Trajectory, Brinley Nichole Stevens

Theses and Dissertations

Integration is a core concept of calculus. As such, significant work has been done on understanding how students come to reason about integrals, including both the definite integral and the accumulation function. A path towards understanding the accumulation function first, then the definite integral as a single point on the accumulation function has been presented in the literature. However, there seems to be an accessible path that begins first with understanding the definite integral through an Adding Up Pieces (AUP) perspective and extending that understanding to the accumulation function. This study provides a viable hypothetical learning trajectory (HLT) for beginning …

Preventing Alzheimer's: Effects Of Second Language Acquisition In Older Populations, Joshua Rhead Jun 2021

Preventing Alzheimer's: Effects Of Second Language Acquisition In Older Populations, Joshua Rhead

Undergraduate Honors Theses

Alzheimer’s disease continues to be a problem that medicine has few answers for. As a result, much research has been focused on finding a cure as well as interventions to help prevent the onset of the disease. One such intervention that has been proposed is to improve the brain’s efficiency and connectivity. A controversial method of achieving these results is through second language acquisition. Many provide evidence for or against the benefits of this intervention, but much remains unclear. Most of these studies focus on cognitive function and functional connectivity in language areas, but the default mode network, which is …

Addressing Melanoma Risk In Families, Rebecca B. Roy, Deborah O. Himes Jun 2021

Addressing Melanoma Risk In Families, Rebecca B. Roy, Deborah O. Himes

Student Works

Melanoma is one of the top 10 cancers in the United States. It is an aggressive and potentially fatal skin cancer. Up to 10% of all people diagnosed with melanoma have a positive family history of melanoma and a family history with a first degree relative can increase the risk for family members by 75%. Poor family communications often result in first degree relatives’ lack of knowledge about risk and prevention for melanoma. Considering this lack of knowledge, primary care providers have the opportunity to assess risk; teach and encourage prevention measures; teach and perform skin exams; and refer to …

A Comparison Analysis Of Five Instructors’ Commenting Patterns Of Audio And Written Feedback On Students’ Writing Assignments, Andrew J. Cavanaugh, Liyan Song Jun 2021

A Comparison Analysis Of Five Instructors’ Commenting Patterns Of Audio And Written Feedback On Students’ Writing Assignments, Andrew J. Cavanaugh, Liyan Song

Journal of Response to Writing

Instructors often use text-based methods when giving feedback to students on their papers. With the development of audio recording technologies, audio feedback has become an increasingly popular alternative to written feedback. This study analyzed five instructors’ commenting patterns of both written and audio feedback. The five instructors, who taught sections of the same undergraduate composition class, provided written feedback to students on one writing assignment and audio feedback on another writing assignment. A mixed-methods research methodology was employed for the study. Data were collected through surveys, students’ writing assignments, digital audio files (for audio feedback), and interviews. The findings indicated …

Sensory Sensitivity And Intolerance Of Uncertainty Influence Anxiety In Autistic Adults, Karys M. Normansell-Mossa Jun 2021

Sensory Sensitivity And Intolerance Of Uncertainty Influence Anxiety In Autistic Adults, Karys M. Normansell-Mossa

Theses and Dissertations

Several models of anxiety in autistic adults have focused on the role of intolerance of uncertainty which has biological and evolutionary bases, as a cognitive explanation for the high prevalence of anxiety in autism. This framework suggests that all people are born with a healthy level of intolerance of uncertainty, and as we develop, this intolerance is lessened as we learn when situations are safe and begin to understand and manage the uncertainty. This process of learning about managing uncertainty does not happen in the same way in those who are high in autistic traits, which could be the reason …

Parental Incarceration And Juvenile Delinquency: The Role Of Gender, Kirstie S. Weyland Jun 2021

Parental Incarceration And Juvenile Delinquency: The Role Of Gender, Kirstie S. Weyland

Theses and Dissertations

Parental incarceration is connected to many negative outcomes for children including negative externalizing behaviors. Most studies are not conclusive in determining whether maternal incarceration or paternal incarceration has a more detrimental impact on children. This study looks at a sample of 2,458 youth from the Fragile Families and Child Well-Being Study (FFCWS) and their parents and compares the gender of the incarcerated parent and that of the child to determine if there are differences in the risk of delinquent behavior among adolescent children. Results found that parental incarceration overall increased the risk of juvenile delinquency and that female children are …

Pegylation Stabilizes The Conformation Of Proteins And The Noncovalent Interactions Within Them, Steven R. E. Draper Jun 2021

Pegylation Stabilizes The Conformation Of Proteins And The Noncovalent Interactions Within Them, Steven R. E. Draper

Theses and Dissertations

PEGylation has been used for decades to enhance the pharmacokinetic properties of protein therapeutics. This method has been effective at increasing the serum half-life of these drugs, but the mechanism of how it does this is unclear. Chapter 1 is an introduction to the methods of PEGylation. In chapter 2 we show that the effect of PEGylation on the conformational stability of the WW domain differs based on amino acid linker and conjugation site. We show that all positions in the WW domain that were tested can be stabilized by at least one amino acid linker. The rate of proteolysis …

Population Dynamics Of Mule Deer (Odocoileus Hemionus): Maternal Effects And De Novo Genome, Sydney Lamb Jun 2021

Population Dynamics Of Mule Deer (Odocoileus Hemionus): Maternal Effects And De Novo Genome, Sydney Lamb

Theses and Dissertations

Population dynamics of large ungulates are complex and vary with fluctuations in factors such as predation, resource availability, human disturbance, and weather (Gaillard et al. 1998, Forrester and Wittmer 2013). These regulating factors exhibit similar effects on ungulate populations by changing vital rates such as birthrate, death rate, emigration or immigration (Gaillard et al. 2000). To better understand the mechanisms influencing population change, it is useful to involve tools from multiple disciplines (Krausman et al. 2013). Here we explore population dynamics of mule deer (Odocoileus hemionus) through the lenses of two distinct fields: population ecology and genomics. In the first …

Remote Sensing And Spatial Variability Of Leaf Area Index Of Irrigated Wheat Fields, Austin Paul Hopkins Jun 2021

Remote Sensing And Spatial Variability Of Leaf Area Index Of Irrigated Wheat Fields, Austin Paul Hopkins

Theses and Dissertations

Leaf area index (LAI) is a versatile indicator of crop growth that is used to estimate evapotranspiration (ET), monitor nitrogen status, and estimate crop yield. Traditional methods for measuring LAI can be improved using high resolution remote sensing. The aim of this study was to compare approaches for estimating LAI from UAV-derived visible vegetation indices. Coincident ground-based and remotely sensed data were obtained from two irrigated wheat fields and were sampled at a total of 5 events in 2019 and 2020. Ground-based LAI was measured with a ceptometer and remotely sensed images were collected using a consumer-grade UAV. Mosaiced orthophotos …

The Etiology Of Mdd In Sexual Minority Youth And Its Implications For Treatment, Keith Burns Jun 2021

The Etiology Of Mdd In Sexual Minority Youth And Its Implications For Treatment, Keith Burns

Intuition: The BYU Undergraduate Journal of Psychology

Greater tolerance and understanding of homosexuality, transgenderism, and other forms of gender nonconformity have sparked an increased effort to reach out to and help sexual minorities (i.e., groups whose sexual identity, orientation, or practices differ from cisgender heterosexuality), especially those who experience mental health challenges. Despite immense progress in society, deeply rooted social stigma, prejudice, and discrimination have often left sexual minorities feeling bullied, ostracized, and isolated, which tends to reinforce a host of negative mental health outcomes, such as increased risk of major depressive disorder (MDD) and suicidality (Hatchel et al., 2018). While mental health clinicians have become increasingly …

Failure To Report: The Detrimental Effects Following Sexual Assault, Lindsey R. Osborne Jun 2021

Failure To Report: The Detrimental Effects Following Sexual Assault, Lindsey R. Osborne

Intuition: The BYU Undergraduate Journal of Psychology

Sexual assault is a prominent issue in society, yet many people remain unaware of the serious effects following sexual assault. Victims who report to legal authorities tend to experience disbelief and blame because of the prevalence of rape myths. Due to the severity of the trauma, hormones released by the brain hinder proper brain functioning and can cause a little-known evolutionary response termed tonic immobility (TI). The psychological outcome of sexual assault commonly results in or worsens several psychological conditions, including depression, anxiety, PTSD, and drug and alcohol abuse. Guilt, self-blame, and adverse emotions are accelerated with negative interactions while …

Sociocultural Factors Of Female Sexual Desire And Sexual Satisfaction, Matysen Evensen Jun 2021

Sociocultural Factors Of Female Sexual Desire And Sexual Satisfaction, Matysen Evensen

Intuition: The BYU Undergraduate Journal of Psychology

Historically, research on the human sexual-response cycle has not accounted for individual differences in gender and context. As a circular female response cycle was introduced in the latter end of the 20th century, differentiation between male and female sexuality was embraced, and individual variation between women became commonly known for the first time. As part of this historical shift, sexual desire became an integral part of the sexual experience (Basson, 2000). Most research on female sexual desire focuses on low desire and diagnosable conditions, but, among researchers, there is a growing consensus for additional focus into the roots of female …

More Than Stories: Indigenous Environmental Reciprocity In The Poetry Of Kathy Jetñil-Kijiner, Rebecca Purse Jun 2021

More Than Stories: Indigenous Environmental Reciprocity In The Poetry Of Kathy Jetñil-Kijiner, Rebecca Purse

Theses and Dissertations

This thesis brings to the forefront the traditional stories Marshallese poet, performer, and climate change activist Kathy Jetñil-Kijiner shares in her published poetry. Indigenous studies scholars agree that Indigenous stories have power--power to change, power to inform, and power to heal. The traditional stories in Jetñil-Kijiner's poetry reveal the power of the environment and the potential relationships that can exist between humans and natural beings. While these traditional stories work to disrupt the narrative that Indigenous perspectives, knowledges, and cultures are somehow inferior to their colonial neighbors', they also assert the need for a return to environmental reciprocit--or the establishment …

The Effects Of Shed Antler Hunting On Ungulate Movement, Space-Use And Resource Selection, Steven B. Bates Jun 2021

The Effects Of Shed Antler Hunting On Ungulate Movement, Space-Use And Resource Selection, Steven B. Bates

Theses and Dissertations

Shed antler hunting has increased in popularity during the past decade, but little is known about how this recreational activity affects ungulate movements and space use. We placed geographic positioning system (gps)-collars on 133 bighorn sheep (Ovis canadensis), bison (Bison bison), and mule deer (Odocoileus hemionus) to quantify their movements, space use, and resource selection during shed antler hunts on Antelope Island Utah, USA, from 2012 to 2015. In Chapter 1, we calculated means and 95% confidence intervals for distance moved during 90-minute segments (16 points/day); pre-event (control, seven consecutive days prior to event), event (one to two days), and …

The Effects Of Interspecific Competition And Predation On Survival Of Neonate Mule Deer, Daniel W. Sallee Jun 2021

The Effects Of Interspecific Competition And Predation On Survival Of Neonate Mule Deer, Daniel W. Sallee

Theses and Dissertations

Mule deer (Odocoileus hemionus) populations are influenced by multiple factors, including interspecific competition and predation. Interspecific competition can affect resource acquisition and survival through altering space use and access to preferred habitat. Mule deer in some areas alter space use in the presence of competing species, including bison (Bison bison), cattle (Box taurus), elk (Cervus canadensis), and feral horses (Equus caballus), however the influence of competition on survival of mule deer during specific life history stages, such as birthing and rearing of neonates, is largely unknown. In addition to competition, predation can influence mule deer populations and even limit population …

Observations Of Atypical Habitat Use By Foothill Yellow-Legged Frogs (Rana Boylii) In The Coast Range Of California, Jeff A. Alvarez, Jeffery T. Wilcox Jun 2021

Observations Of Atypical Habitat Use By Foothill Yellow-Legged Frogs (Rana Boylii) In The Coast Range Of California, Jeff A. Alvarez, Jeffery T. Wilcox

Western North American Naturalist

Foothill Yellow-legged Frogs (Rana boylii) have experienced extreme range-wide declines in recent decades. This stream-dwelling species is thought to be in decline primarily due to the alteration of streams through anthropogenic water development, the effects of which may be exacerbated by climate change. Although R. boylii has long been considered an obligate inhabitant of perennial streams, recent observations indicate that this species exhibits greater behavioral plasticity in habitat use, particularly for reproduction. Herein, we report on several observations of R. boylii using atypical habitat for both refuge and reproduction. We found several R. boylii individuals reproducing within lentic …

Lesser Long-Nosed Bat (Leptonycteris Yerbabuenae) Range Expansion Into Northern Grant County, New Mexico, Keith Geluso, Kenneth N. Geluso Jun 2021

Lesser Long-Nosed Bat (Leptonycteris Yerbabuenae) Range Expansion Into Northern Grant County, New Mexico, Keith Geluso, Kenneth N. Geluso

Western North American Naturalist

The lesser long-nosed bat (Leptonycteris yerbabuenae) previously was known only from extreme southwestern New Mexico in southern Hidalgo County. Herein, we documented L. yerbabuenae from northern Grant County along the Gila River on the southern edge of the Mogollon Plateau, which represents a 110-km range expansion to the north. We captured mostly volant young-of-the-year (68.5%) and adult females (25.9%) as well as a few adult males (5.6%) in September 2019. With assistance from local residents, we have evidence that nectar-feeding bats have been using hummingbird feeders in the area at least since 2014 and are a relatively …

Put The Score On The Back Burner: Coach–Athlete Relationships And Anxiety, Tiffany Peterson May 2021

Put The Score On The Back Burner: Coach–Athlete Relationships And Anxiety, Tiffany Peterson

Intuition: The BYU Undergraduate Journal of Psychology

Anxiety is a very prevalent mental disorder among adolescents and can be unfavorable to their developing mental, cognitive, and social health. Although it comes in many forms, social anxiety disorder, which can affect peer relations, academic success, and sport performance, can be especially difficult during teenage years. More specifically, high school sports provide many situations and stressors that can trigger social anxiety. Some major aspects of high school sports that can trigger social anxiety are working with teammates and learning from coaches. This review seeks to provide a better understanding of the effect that the coach–athlete relationship has on anxiety …

Anxiety Disorders: A Review Of Neurobiological Structures, Neurocognitive Expressions, And Treatment Options, Lucy A. Jessee May 2021

Anxiety Disorders: A Review Of Neurobiological Structures, Neurocognitive Expressions, And Treatment Options, Lucy A. Jessee

Intuition: The BYU Undergraduate Journal of Psychology

There are many types of anxiety disorders, all of which are most recognizable by their display of excessive fear or worry. In order to fully recognize and treat anxiety disorders, individuals must understand the neurobiological causes and neurocognitive expressions of the disorder. This review examines 16 studies on the neurobiology, cognitive symptoms, and treatment options for anxiety disorders. This revealed that the amygdala, prefrontal cortex, visual cortex, and superior temporal gyrus play a substantial role in anxiety disorders. These biological substrates are then linked to common cognitive symptoms of anxiety disorders, including executive function deficits. Finally, both neuropharmacological therapy and …

Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality, Colt Halter May 2021

Empathy And Fairness In Nonhuman Primates: Evolutionary Bases Of Human Morality, Colt Halter

Intuition: The BYU Undergraduate Journal of Psychology

Darwin offered an evolutionary perspective on the origins of human morality, suggesting that humans share a biological foundation with nonhuman primates. This paper reviews the current literature on moral and prosocial behaviors of nonhuman primates, specifically examining whether nonhuman primates exhibit behaviors that are typical of empathy and fairness. The literature documents that nonhuman primates exhibit empathetic behaviors regarding emotional contagion and sympathetic concern. There is also evidence that nonhuman primates have a sense of fairness, seen in their reciprocal behaviors and aversion to inequity. Taken together, this suggests that there are evolutionary roots of morality, lending empirical support to …

Guilt By Obesity: A Closer Look At Obesity Stigmas, Loriana Goulding May 2021

Guilt By Obesity: A Closer Look At Obesity Stigmas, Loriana Goulding

Intuition: The BYU Undergraduate Journal of Psychology

Obesity stigmas have led to an increased interest in the body-positivity movement in recent years. However, despite the decreasing discrimination and shaming of the obese, many people still consciously and unconsciously adhere to obesity stigmas and myths. These false beliefs are harmful not only to obese individuals but also to society, given that over 1/3 of the U.S. adult population is now obese (Centers for Disease Control and Prevention, 2017). These stigmas can be especially harmful to obese individuals who are victims of wrongdoings and to obese individuals who are accused of a wrongdoing (Yamawaki, Riley, Rasmussen, & Cook, 2018). …

The Comorbidity Of Drug And Alcohol Consumption In Relation To Mental Health Disorders, Sydney Dawson May 2021

The Comorbidity Of Drug And Alcohol Consumption In Relation To Mental Health Disorders, Sydney Dawson

Intuition: The BYU Undergraduate Journal of Psychology

The constantly increasing use of drugs and alcohol in young adults has created great controversy in the medical community on the long-term effects of these substances. The average brain development of adolescence and young adults is not complete until the age of 25, though drug and alcohol intake occur across the United States at younger ages each year. Impulsive behavior and underdeveloped neural pathways create a strong pull for addiction formulations and the development of severe mental-health problems. This paper reviews the positive and negative effects of illicit drugs and alcohol intake and their comorbidity with mental health disorders. There …

Specific Challenges Faced By Females With Autism Spectrum Disorder, Brad W. Davis May 2021

Specific Challenges Faced By Females With Autism Spectrum Disorder, Brad W. Davis

Intuition: The BYU Undergraduate Journal of Psychology

Autism Spectrum Disorder (ASD) is a complicated developmental condition. ASD is typically known as a male-associated disorder with three to four times as many males diagnosed with the disorder than females (Loomes, Hull, & Mandy, 2017). Recent studies on the differences between males and females with ASD have recognized an underdiagnosis of females with ASD. Researchers have found that females with ASD have a specific set of mannerisms and struggles that differ from their male counterparts, which may be “camouflaging” the females into society (Lai et al., 2019). Many undiagnosed females with ASD are not receiving the mental, emotional, and …

Applications Of And Algorithms For Genome Assembly And Genomic Analyses With An Emphasis On Marine Teleosts, Brandon D. Pickett May 2021

Applications Of And Algorithms For Genome Assembly And Genomic Analyses With An Emphasis On Marine Teleosts, Brandon D. Pickett

Theses and Dissertations

The burgeoning frequency of genome sequencing in recent years is a testament to both the improvements in sequencing technologies and the utility of genomic analyses for biological discovery. The rapid proliferation in technological advancements and availability of complementary data types and techniques has obfuscated the optimal process of genome assembly and raised the barrier to entry to unprecedented levels. In this dissertation, we describe the genome assemblies performed for several marine teleosts and discuss the algorithms and applications required for genome assembly, including some of our specific contributions to the genome assembly and annotation space. In Chapter 1 and Chapter …

Courtship Behavior Of The Meadow Jumping Mouse (Zapus Hudsonius), Ethan A. Brem, William J. Israelsen May 2021

Courtship Behavior Of The Meadow Jumping Mouse (Zapus Hudsonius), Ethan A. Brem, William J. Israelsen

Western North American Naturalist

We describe the first recorded observations of courtship behavior of the meadow jumping mouse (Zapus hudsonius) made in wild-caught and captive-reared animals. Male meadow jumping mice performed a series of courtship behaviors upon approach to the female, including rapid fanning of the muzzle with the forelimbs, self-grooming, muzzle fanning, retreat, and eventual mounting attempts. During courtship, female jumping mice may retreat, ignore the courting male, or bat at the male with forelimbs until the male retreats. Active rejection of the courting male by the female is suggestive of female mate choice in this species.

Ecological Analyses Of Macroinvertebrate And Fish Species In Six Streams On A Louisiana Military Base From 2001 To 2019, Danielle Joerger, Marsha Williams, Lance Williams May 2021

Ecological Analyses Of Macroinvertebrate And Fish Species In Six Streams On A Louisiana Military Base From 2001 To 2019, Danielle Joerger, Marsha Williams, Lance Williams

Open Water Journal

An in-depth ecological analysis of how and why the aquatic community changes over time was conducted for 6 streams on the Fort Polk military base in Louisiana using data collected from 2001 to 2019. Fort Polk is a unique location as nineteen first-order streams are located on the premises belonging to three separate drainages. The primary goal was to determine whether temporal or between-drainage variation has a larger effect on community structure. To accomplish this the effects of disturbance on fish and macroinvertebrate assemblages was determined temporally and between drainages. Several hypotheses were drawn from this: 1) temporally, assemblages exhibit …

Drought In The West: Embedded Water Demand Stationarity Compromises System Vulnerability Analysis, Ryan C. Johnson, Margaret Wolf, Logan Jamison, Steven Burian, Carlos A. Oroza, Paul D. Brooks, Courtenay Strong, Jesse Stewart, Tracie Kirkham May 2021

Drought In The West: Embedded Water Demand Stationarity Compromises System Vulnerability Analysis, Ryan C. Johnson, Margaret Wolf, Logan Jamison, Steven Burian, Carlos A. Oroza, Paul D. Brooks, Courtenay Strong, Jesse Stewart, Tracie Kirkham

Open Water Journal

Hydrological drought is challenging managers of western U.S. snowpack-dependent urban water systems. Snowpack, reservoir storage, streamflow dynamics, and demand are routinely assessed to guide water system management and operations, assuming per-capita demand stationarity. Using the Salt Lake City Department of Public Utilities and two drought scenarios, we investigate water system vulnerability differences between unchanging industry per-capita forecasting methods and dynamic demands driven by hydro-climate-demand relationships. The introduction of dynamic demands estimates a 42% reduction in system vulnerability during supply limiting conditions than the industry methods. These modeled water use behaviors also suggest a reduction in the peak timing and volume …

A Simple Method For Restraint Of Small Mammals For Sampling Blood Or Tissue In The Field, John L. Orrock May 2021

A Simple Method For Restraint Of Small Mammals For Sampling Blood Or Tissue In The Field, John L. Orrock

Western North American Naturalist

Because wild rodents often harbor zoonotic pathogens that can be transmitted via saliva, urine, or feces (e.g., hantaviruses), researchers can be at risk when collecting rodent blood or tissue samples that are required for innumerable assays (e.g., infection status, hormone assays, etc.). I describe how inexpensive, readily available 50-mL centrifuge tubes can be easily modified to create a handling tube for the safe restraint of small rodents while a blood and/or tissue sample is collected from the tail. This approach has been used to successfully sample thousands of deer mice (Peromyscus maniculatus), the primary host for Sin Nombre …
