An Assessment Of Cattle Traffic On, And Seed Dispersion Patterns Of, Sclerocactus Wrightiae, David D. Lariviere Aug 2023

An Assessment Of Cattle Traffic On, And Seed Dispersion Patterns Of, Sclerocactus Wrightiae, David D. Lariviere

Theses and Dissertations

Cattle grazing has been a historic use of rangelands in Utah since Pioneer settlement in the mid 1800's. Wright fishhook cactus is a small globose cactus endemic to an area of 280,000 ha in south-central Utah and was listed as endangered in October of 1979, by the U.S. Fish and Wildlife Service (USFWS). By 2010, concerns were expressed that soil compaction in proximity to the cactus posed a threat to this species, though there was no empirical data to support such concern. In order to assess the impact of cattle traffic on Wright fishhook cactus, we used an imprint device …

Determination Of A Surrogate For Plutonium Electrorefining, Greg Chipman, Bryant Johnson, Suhee Choi, Chao Zhang, Michael Simpson, Devin Rappleye Aug 2023

Determination Of A Surrogate For Plutonium Electrorefining, Greg Chipman, Bryant Johnson, Suhee Choi, Chao Zhang, Michael Simpson, Devin Rappleye

Faculty Publications

Conducting research experiments on plutonium electrorefining is difficult due to the significant hazards and regulations associated with nuclear materials. Finding a surrogate for plutonium electrorefining studies would enable more fundamental research to be conducted. Potential surrogates were first identified by determining the physical properties required to conduct electrorefining at the same conditions commonly used in plutonium electrorefining, a molten metal and molten CaCl2 at 1123 K. Ce-CeCl3, In-InCl3, and Pb-PbCl2 were the only potential surrogates identified using these constraints. Sn-SnCl2 was also tested at these same conditions. More potential surrogates were identified by …

Side-Channel Leakage From The Advanced Encryption Standard On Field Programmable Gate Arrays, Kaden Makechnie-Hardy Aug 2023

Side-Channel Leakage From The Advanced Encryption Standard On Field Programmable Gate Arrays, Kaden Makechnie-Hardy

Undergraduate Honors Theses

As field programmable gate arrays (FPGAs) perform increasingly critical cryptography, researchers study the safety of these computations. One such compromise on the safety of cryptography is the side-channel attack. These attacks exploit sources of information called leakage that escape a cryptographic system in ways the original design did not intend. One dimension of a successful side-channel attack is the collection of leakage. This research configures the Advanced Encryption Standard (AES) on an FPGA and demonstrates strategies for collecting three types of side-channel leakage: power consumption, temperature emissions, and ring oscillations.

The Effect Of Speaking Context On Articulatory Kinematics In Habitual And Clear Speech, Lauren Elizabeth Clarke Aug 2023

The Effect Of Speaking Context On Articulatory Kinematics In Habitual And Clear Speech, Lauren Elizabeth Clarke

Theses and Dissertations

This study examined the effect of speaking contexts on articulatory kinematics in habitual and clear speech conditions. Ten male and 10 female participants (ages 18"“29) completed speaking tasks in three contexts and two conditions. The contexts were word, phrase, and passage, with both mid-sentence and end of-sentence stimuli in the phrase and passage contexts. The two conditions were habitual and clear speech. Participants had sensors attached to the mid-tongue, jaw, lower lip, and upper lip, and an electromagnetic articulograph tracked their movements. Three tokens for each stimulus were analyzed for duration, displacement, and velocity. Articulatory coordination was measured through absolute …

Engagement In Secondary Mathematics Group Work: A Student Perspective, Rachel H. Jorgenson Aug 2023

Engagement In Secondary Mathematics Group Work: A Student Perspective, Rachel H. Jorgenson

Theses and Dissertations

In the realm of academic engagement research, students are valuable sources of information to learn how and why students often engage unproductively in mathematics group work. However, although secondary mathematics students are often expected to engage in meaningful mathematical discourse in a small group setting, little research has been conducted to better understand student engagement in this setting from the perspective of the students themselves. This thesis attempts to understand how one junior high student described his own engagement in mathematics small group work as well as what factors influenced this engagement. By conducting several cycles of observations and interviews …

Predictors Of Adherence To A Brief Sleep Extension Intervention In Emerging Adults, Isabella D. Wright Aug 2023

Predictors Of Adherence To A Brief Sleep Extension Intervention In Emerging Adults, Isabella D. Wright

Theses and Dissertations

Objectives: It is uncertain what characteristics predict adherence to a brief sleep extension intervention, like that offered in primary care settings. This study examined how mental health concerns (i.e., depression, anxiety, stress), self-control, baseline sleep characteristics, and physical activity predicted adherence to a brief sleep extension intervention. Methods: 184 young adults (ages 18-25; m = 20.96) were asked to extend their nightly sleep to eight hours for one week. Sleep was tracked using actigraphy. Baseline sleep quality, baseline daytime sleepiness, depression, anxiety, stress, self-control, and physical activity were assessed. Results: Poorer baseline sleep quality predicted better adherence (p = 0.002). …

Does Media Facilitate Parent-Child Race Discussions? A Mixed-Method Study Of White Families, Children's Media, And Implicit Bias During Early Childhood, J. Andan Sheppard Aug 2023

Does Media Facilitate Parent-Child Race Discussions? A Mixed-Method Study Of White Families, Children's Media, And Implicit Bias During Early Childhood, J. Andan Sheppard

Theses and Dissertations

The study aimed to investigate through mixed methods how White parents approach race discussions with their children, the factors influencing the discussions, and the implications for promoting constructive conversations. The qualitative analysis of the race discussions revealed that White parents preferred ambiguous or scientific language and diverted the discussion to topics other than race, such as gender or general body characteristics. Discussions often involved referencing personal examples of individuals from racial minority backgrounds, even if they were not personally acquainted. The quantitative analysis expanded and clarified these findings, with parent characteristics, such as education level and the frequency of color-evasive …

Characterization Of Phage-Host Interactions And Its Impact On Tail Fiber Evolution, Jessica Marie Lewis Aug 2023

Characterization Of Phage-Host Interactions And Its Impact On Tail Fiber Evolution, Jessica Marie Lewis

Theses and Dissertations

Beyond the scope of what our unaided eyes can see is a diverse and rich microbial community that greatly impacts each of our lives. Bacteria are microscopic organisms that can grow, develop, divide, and even rapidly evolve to adapt to new changes in their environment. Because of this, bacteria have gained the ability to thrive in extreme biological niches ranging from the high temperature and pressure surrounding hydrothermal vents to the harsh acidic conditions of our stomachs. One adaptation attracting attention, however, is their capability to survive in the presence of common and even last-resort antibiotics. The WHO recently reported …

Predicting The Best Birds And Bees: Parental-Efficacy As A Mediator Between Parental Factors And Parent-Child Sex Communication, Meg O. Jankovich Aug 2023

Predicting The Best Birds And Bees: Parental-Efficacy As A Mediator Between Parental Factors And Parent-Child Sex Communication, Meg O. Jankovich

Theses and Dissertations

Recent literature on parent-child sex communication (PCSC) has identified optimal sex communication as being not only frequent, but also open in quality, and proactive in timing. However, no studies have sought to understand what motivates parents to participate in this type of optimal parent-child sex communication, nor assessed these relationships longitudinally. Using Self-Determination Theory (SDT) to inform the analysis, this study investigated parent characteristics (parent's sexual self-concept and parenting dimensions) that may longitudinally predict optimal PCSC. This study further examined whether parental sex communication efficacy mediated these relationships. The sample included 607 mother-child dyads, and the father-figure when available (mother-father-child …

Loading Force In Recreational Runners And Its Effect On Achilles Tendon Biomechanical Properties, Joshua K. Sponbeck Aug 2023

Loading Force In Recreational Runners And Its Effect On Achilles Tendon Biomechanical Properties, Joshua K. Sponbeck

Theses and Dissertations

Background: Achilles tendinopathy is a common debilitating running related injury. Achilles tendon loading force has been hypothesized as a contributor to Achilles tendinopathy. Loading force through the Achilles tendon during running is impacted by many factors such as footwear and foot strike pattern. Achilles tendon biomechanical (Achilles tendon cross-sectional area, thickness, echogenicity, stiffness, and T2*) responses to loading forces are variable and measurable in vivo. These responses impact the physiologic function of the tendon. Aims: 1) To evaluate baseline Achilles tendon biomechanical characteristics associated with a runner's habitual foot strike pattern. 2) To evaluate single running bout Achilles tendon biomechanical …

A Refuge And A Bridge: Native American Women's Tribal College Experiences, Morgan Duffy Aug 2023

A Refuge And A Bridge: Native American Women's Tribal College Experiences, Morgan Duffy

Theses and Dissertations

This study, which focuses on the experiences of Native women attending a tribal college of the Northern Cheyenne Nation, responds to the call by Baird-Olson and Ward (2000) and Almeida (1997) for research that allows Native women, or the "hidden half," to tell their stories. Scant research has examined the value of tribal schools for Native American women and the experiences they have had in relation to their reservation and college lives. Providing narratives of women's experiences can illuminate how higher education in tribal college settings holds multiple values for Native women students as it acts as a refuge and …

Barriers And Facilitating Factors Of Sleep Assessment/Screening Among School Psychology Practitioners, Tyler Jjay Landon Storey Aug 2023

Barriers And Facilitating Factors Of Sleep Assessment/Screening Among School Psychology Practitioners, Tyler Jjay Landon Storey

Theses and Dissertations

Sleep is an important and necessary part of life. While the biological need for sleep among school-aged individuals has not changed over the years, the quality and quantity of their sleep has. School-aged children reporting sleep deficits in the United States is on the rise and a significant body of research establishes associations between a lack of sleep and lower cognition as well as psychological and behavioral problems. These associations can heavily influence the academic progress and success of students. School psychologists are in a unique position to identify and provide support to individuals with sleep issues. Unfortunately, there is …

The Generalizability Of Proposed Theoretical Factor Models For Common Assessments For Specific Learning Disability In Reading Using A Community Sample, Sean B. Vanhille Aug 2023

The Generalizability Of Proposed Theoretical Factor Models For Common Assessments For Specific Learning Disability In Reading Using A Community Sample, Sean B. Vanhille

Theses and Dissertations

Specific learning disabilities (SLD) are among the most diagnosed developmental disorders in children, with specific learning disability in reading (SLDR) as the most common. SLDR typically occurs due to deficits in phonological processing that can negatively impact decoding and/or reading comprehension skills. Reading deficits are often diagnosed using formal assessments such as the Comprehensive Test of Phonological Processing (CTOPP-2), the Gray Oral Reading Test (GORT-5), the Wechsler Intelligence Scale for Children (WISC-V), and the Woodcock Johnson Achievement Battery (WJ-IV-A). I did not find any research in which the theoretical factor models proposed in the technical manuals of these assessments were …

Theses and Dissertations

Conducting research experiments on plutonium electrorefining is difficult due to the significant hazards and regulations associated with nuclear materials. Finding a surrogate for plutonium electrorefining studies would enable more fundamental research to be conducted. Potential surrogates were identified by determining the physical properties required to conduct electrorefining using a molten metal and molten salt in CaCl2 at 1123 K. More potential surrogates were identified by changing the matrix salt to be a LiCl-KCl-CaCl2 eutectic salt with electrorefining conducted at 673-773 K. Ce-CeCl3, In-InCl3, Zn-ZnCl2, Sn-SnCl2, and Bi-BiCl¬3 were investigated as potential plutonium electrorefining surrogates. Ce electrorefining in molten CaCl2 resulted …

Parents' Perceptions Of The Importance Of Teaching Mathematics: A Q-Study, Ashlynn M. Holley Aug 2023

Parents' Perceptions Of The Importance Of Teaching Mathematics: A Q-Study, Ashlynn M. Holley

Theses and Dissertations

Mathematics education has gone through multiple reform efforts over the last century and continues to be the target of improvement efforts. Past changes in curriculum and goals have sometimes led to heated debates between various stakeholders. Knowing the views of different stakeholders can help determine what common ground there is between these different groups and where areas of disagreement might arise. Parents are especially important to understand because they have been influential in past reform efforts. Despite the importance of parents' opinions, little research has been conducted concerning their perspectives on the importance of mathematics teaching. Using Q-methodology, I was …
