Adolescent Mental Health And Social Media: The Roles Of Psychosocial Development And Online Interaction, Mark L. Ferguson

All Graduate Theses and Dissertations, Fall 2023 to Present

Social media has become an integral part of adolescent life, and its effects on adolescents’ mental health has been studied for over twenty years. However, the research approaches used to discover connections between adolescent social media use and their mental health have been diverse, and findings have varied over time. This study sought to explore the potential relationships between adolescent social media use and mental health by including several different variables that aren’t typically accounted for in the same study, such as attachment to parents and peers, internal psychological development, emotional intensity towards social media use, and how adolescents feel …

Instrument Development For Determining High School Students’ Epistemological And Ontological Beliefs Regarding Photography, Earl Stanford Maeser Jr.

All Graduate Theses and Dissertations, Fall 2023 to Present

Research in educational psychology has shown that students' beliefs about knowledge—known as personal epistemology—significantly impact their academic success. However, accurately measuring these beliefs has proven to be challenging due to the lack of reliable and valid tools. This study addresses this gap by developing and testing two tools aimed at assessing high school students' beliefs about knowledge and reality in the context of photography: the Photographic Knowledge Questionnaire (PKQ) and the Photographic Reality Questionnaire (PRQ).

Photography, with its strong ties to reality and representation, provides a unique way to explore personal beliefs about the nature of reality and how knowledge …

Analysis Of An Outdoor Pilot-Scale Rotating Algae Biofilm Reactor For Power Optimization, Ash-Enhanced Productivity, And Nutrient Uptake, Peter F. Jeppesen

All Graduate Theses and Dissertations, Fall 2023 to Present

Outdoor testing of a rotating algae biofilm reactor (RABR) was performed to see how well it could remove nutrients from water and produce algae. By adjusting the operation settings, we found the lowest power needed to remove nitrogen and phosphorus. The lowest power values needed were 1.36 kWh per kilogram of nitrogen and 20.1 kWh per kilogram of phosphorus. The algae production rate reached a maximum of 7.09 grams per square meter per day. Detailed analysis showed that the reactor worked like a continuous flow system, and the performance was influenced by factors including light and temperature. The results also …

Is That Controversial Or Is It Just Me?, Joseph D. Cochran

All Graduate Theses and Dissertations, Fall 2023 to Present

The purposes of this study were to explore the decision-making process behind delineating issues as controversial or not, identify the risks considered by administrators when faced with potentially controversial issues, and provide recommendations for educators to consider in their own deliberations. I interviewed seven charter school principals and used thematic analysis to explore the influence of contained risk-taking on administrator decision-making concerning controversial issues. The findings of this study suggest that administrators generally consider the same risks their teacher counterparts do but often prioritize larger-scale solutions that ensure equity for the entire school. The products of this process emphasize a …

A Mass Balance Model Of The Great Salt Lake, Ut With Adaptive Management Applications, Diana Dunn

All Graduate Theses and Dissertations, Fall 2023 to Present

The Great Salt, Utah, USA is a saline lake that provides critical habitat for ecologic communities and generates $1.3 billion annually. It has gone through detrimental change since the 20^th century. Streamflow reaching the lake has been decreased by upstream withdrawal for industrial and municipal use, causing the lake level to drop and salinity to increase to unhealthy levels. Further, in 1959, it was segregated into north and south sections by a railroad causeway. Due to the causeway and limited exchange of water through two bridges, the lake sections have significantly different water surface elevation and salinity levels. The …

Detecting Community-Level Ethnic Variation Through Classic Vernal Style Rock Art, Victoria Ramirez

All Graduate Theses and Dissertations, Fall 2023 to Present

The Uinta Basin in Northeastern Utah was where farming first took hold in the far north of western North America. This shift from hunting to farming saw the rise of many farming communities among the Fremont people. These communities left behind stunning rock art known as the Classic Vernal style. Recent studies suggest that these communities were made up of two different groups who came from the Four-Corners area around AD 300, bringing farming with them. This idea means that different cultural groups may have created the Classic Vernal style rock art in the Uinta Basin. By looking closely at …

Relationships Matter: Unpacking Personal And Professional Grief In Archival Labor, Caroline Kinsley, Molly Stothert-Maurer

Journal of Western Archives

Archival donations are often triggered by critical transitions in donors' lives, like the end of a career, the selling of a family home, or the death of a loved one. Because donors approach archives during these transitions, archivists often find themselves in the middle of emotionally charged relationships with donors working through feelings of grief and loss. However, archivists are often unprepared and untrained for this emotionally demanding labor. A literature review reveals that while this is a common experience among archivists, there is very little guidance on how to approach this aspect of donor relations. Other fields that provide …

Zoographics In The Journal Of The Experimental Analysis Of Behavior: Increasing Inclusion Of Female Animals, Amy L. Odum, Kiernan T. Callister, Mariah E. Willis-Moore, Daniel S. Da Silva, David N. Legaspi, Lucy N. Scribner, Josephine N. Hannah

Psychology Faculty Publications

We examined the zoographics, or the characteristics of nonhuman animal subjects, reported for the entirety of the Journal of the Experimental Analysis of Behavior (JEAB) through the most recent complete year (1958–2023). Animal sex in particular was evaluated to determine whether the lack of inclusion of female subjects in other disciplines extends to JEAB. Through systematic coding of all nonhuman empirical articles, we found consistent underreporting of most zoographics and a disproportionate use of male subjects relative to female subjects. Additionally, animal sex was commonly unreported and the inclusion of both male and female subjects was sparse. …

The Primacy Of Density-Mediated Indirect Effects In A Community Of Wolves, Elk, And Aspen, Elaine M. Brice, Eric J. Larsen, Daniel R. Stahler, Daniel R. Macnulty

Aspen Bibliography

The removal or addition of a predator in an ecosystem can trigger a trophic cascade, whereby the predator indirectly influences plants and/or abiotic processes via direct effects on its herbivore prey. A trophic cascade can operate through a density-mediated indirect effect (DMIE), where the predator reduces herbivore density via predation, and/or through a trait-mediated indirect effect (TMIE), where the predator induces an herbivore trait response that modifies the herbivore's effect on plants. Manipulative experiments suggest that TMIEs are an equivalent or more important driver of trophic cascades than are DMIEs. Whether this applies generally in nature is uncertain because few …

Multiscale Analysis Of Thermal Barrier Coated Cfrp Composites Under Thermal Loading, Devin Nielsen, Trenton M. Ricks, Juhyeong Lee

Mechanical and Aerospace Engineering Student Publications and Presentations

Carbon-fiber reinforced polymer (CFRP) composites are commonly used in high performance applications. Although offering several advantages (i.e., superior specific properties and improved structural rigidity), traditional CFRP composites often exhibit poor thermal stability due to a low matrix thermal decomposition temperature. The effective operating temperature of the CFRP composites can be raised by applying an outermost, protective thermal barrier coating (TBC) layer. Prefabricated high void content ceramic TBCs are ideal for composite applications due to their high thermal stability and relatively low thermal conductivity. In this paper, the thermo-mechanical response of the TBCCFRP composite laminate subjected to 500°C are assessed through …

Differential Hepatic Expression Of Mirna In Response To Aflatoxin B1 Challenge In Domestic And Wild Turkeys, Kade Jorud, Kristelle M. Mendoza, Thomas Kono, Roger A. Coulombe, Kent M. Reed

Animal, Dairy, and Veterinary Science Faculty Publications

Aflatoxin B1 (AFB₁) is a major foodborne mycotoxin that poses a significant economic risk to poultry due to a greater degree of susceptibility compared to other agricultural species. Domesticated turkeys (Meleagris gallopavo) are especially sensitive to AFB₁; however, wild turkeys (M. g. silvestris) are more resistant. A lack of functional isoforms of hepatic glutathione S-transferases (GSTs), an enzyme that plays a role in the detoxification of aflatoxin, is suspected as the reason for the increased sensitivity. Previous studies comparing the gene expression of domesticated and wild turkeys exposed to AFB₁ identified …

Origami And Kirigami-Inspired Sandwich Panels For Uam Primary Structural Applications, Kalyan Raj Kota, Juhyeong Lee

Mechanical and Aerospace Engineering Faculty Publications

Foldcore sandwich panels (FSPs) provide highly tailorable structural and multifunctional performance over legacy sandwich panels made with honeycomb or foam cores. In FSP manufacturing, skins and foldcore are made from any flat sheets of unitary or hybrid materials, folded into a desired pattern. Two common folding mechanisms include origami and kirigami: origami core is involved with folding only, while kirigami core is associated with a strategic combination of folding and cutting. Material and core geometry can be determined to satisfy the applications’ performance requirements. Overall, origami- or kirigami-inspired FSPs have the potential to revolutionize the ways to design and …

A New Conceptual And Analytic Framework For Collective Engagement In Mathematics, Tye G. Campbell, Michael A. Lawson

Teacher Education and Leadership Faculty Publications

This paper proposes a new social construct and conceptual-analytic framework for the study of group engagement in mathematics, which we call collective engagement structures. This new framework is offered to address research and practice-identified needs to better understand how individual student dispositions and preferences might interact with group processes to inform student engagement and learning. We demonstrate the collective engagement structures framework using a case study analysis of three middle school students working in a group on a complex mathematics problem. Our analysis details how three students’ individual engagement structures and positional influence interact to form two collective engagement structures: …

Coupled Thermal-Electrical-Mechanical Characteristics Of Lightning Damage In Woven Composite Honeycomb Sandwich Structures, Bin Yang, Juhyeong Lee, Yuchen Zhou, Xiaoshan Liu, C. Guedes Soares, Kunkun Fu, Dongmin Yang

Mechanical and Aerospace Engineering Faculty Publications

In this study, lightning strike damage of woven carbon fibre-reinforced polymer laminates (W-CFRPs) and woven composite honeycomb sandwich panels (W-CHSPs) are simulated using the proposed sequential thermal-electrical-mechanical finite element (FE) coupling model incorporating dielectric breakdown of materials. Surface current with an amplitude of 200 kA and corresponding lightning shockwave overpressure were applied on each composite. The FE model coupled with LaRC05 criterion was used to study the failure behaviours of intralaminar damage and interlaminar delamination of the W-CFRPs and W-CHSPs. A series of lightning strike tests were performed to validate the FE model. Detailed lightning damage assessments and mechanisms were …

Clinical Characteristics Of A Treatment Seeking Sample Of Adults With Misophonia: Onset, Course, Triggers, Context, And Comorbidity, Mercedes G. Woolley, Leila K. Capel, Emily M. Bowers, Julie M. Petersen, Karen Muñoz, Michael P. Twohig

Psychology Faculty Publications

Misophonia is characterized by intense emotional reactions to specific repetitive sounds. The clinical characteristics and developmental course of misophonia remain underexplored, particularly in treatment-seeking adults. In this study, we characterized the onset, symptom progression, trigger noises, and psychiatric comorbidities associated with misophonia. Additionally, we investigated the relationships between these clinical attributes and the severity of self- and clinician-rated misophonia symptoms. The sample included 60 adults with misophonia enrolled in a randomized controlled trial. Most participants (79%) reported symptom onset in childhood and early adolescence, with symptoms often worsening over time. All participants reported being bothered by human produced sounds. However, …

Diagnostic Overshadowing: A Delayed Diagnosis Of Autism Spectrum Disorder In A Deaf Child, Quynh-Chi Dang, Michael Hoffman, Rachel St. John

Journal of Early Hearing Detection and Intervention

Diagnostic overshadowing occurs when a patient with a pre-existing diagnosis presents with symptoms that are attributed to the diagnosis, but actually reflect a separate issue. This diagnostic overshadowing can lead to delays in diagnosis, as well as disparities in health care and outcomes. The following case will provide an example in which diagnostic overshadowing contributed to the delay of an autism diagnosis in a child who is deaf. With at least 40 to 50% of children who are deaf or hard of hearing having at least one co-existing medical/developmental condition, and the current prevalence of autism at 1 in 36 …

A Preliminary Fuzzy Inference System For Predicting Atmospheric Ozone In An Intermountain Basin, John R. Lawson, Seth N. Lyman

Mathematics and Statistics Faculty Publications

High concentrations of ozone in the Uinta Basin, Utah, can occur after sufficient snowfall and a strong atmospheric anticyclone creates a persistent cold pool that traps emissions from oil and gas operations, where sustained photolysis of the precursors builds ozone to unhealthy concentrations. The basin's winter-ozone system is well understood by domain experts and supported by archives of atmospheric observations. Rules of the system can be formulated in natural language ("sufficient snowfall and high pressure leads to high ozone"), lending itself to analysis with a fuzzy-logic inference system. This method encodes human expertise as machine intelligence in a more prescribed …

Fly High! How To Create Senior Capstone Experiences Using Self-Directed Service-Learning Through Instructor Mentorship, Andreas 'Baron' Wesemann

Impact Of County-Level Urbanicity On Quality Of Life For People With Intellectual And Developmental Disabilities In A Rural State., Alyssa M. Smith, Allison Caudill

Developmental Disabilities Network Journal

People with intellectual and developmental disabilities (IDD) face challenges, such as decreased access to physical, environmental, and social health-related services that can negatively impact their overall quality of life (QoL). Additionally, people living in rural communities may experience geographic distancing and other factors, like decreased transportation and available housing, that contribute to increased isolation and decreased health outcomes, overall. It is important to consider the QoL of people with IDD living in these communities given the additional intersectional constraints of rurality and having an intellectual disability or other co-occurring conditions. A secondary data analysis reviewed closed and open-ended survey data …

Applying A Framework Of Epistemic Injustice To Understand The Impact Of Covid-19 On People With Intellectual And Developmental Disabilities, Sarah Lineberry, Matthew Bogenschutz

Developmental Disabilities Network Journal

Epistemic injustice, the theory of unfairness related to knowledge, is a useful framework for understanding the ways in which historic and ongoing marginalization and stereotypes have shaped the ways that people with intellectual and developmental disabilities (IDD) have been impacted by the COVID-19 pandemic. We conducted a scoping review of the literature and divided findings into physical health (cases, hospitalization, and death) and psychosocial outcomes (access to services, mental health symptoms, community participation, etc.). Impacts were then analyzed using the key principles of epistemic injustice. Findings suggest that people with intellectual and developmental disabilities (IDD) experienced high rates of negative …
