General Non-Destructive Evaluation For Friction Stir Welding, Johnathon Bryce Hunt Apr 2024

General Non-Destructive Evaluation For Friction Stir Welding, Johnathon Bryce Hunt

Theses and Dissertations

Friction stir welding (FSW) is an advantageous solid state joining method for many different engineering designs. It was invented in 1991 by TWI and since that time a tremendous amount of research has been executed to understand and implement FSW in a myriad of materials in numerous industries such as aerospace, ship building, train, automotive, energy, agriculture and others. Most industries have strict weld inspection processes to validate a weld before it is put into service. One of the main weld characteristics that is measured is the size of any subsurface volumetric voids. The current standard to test friction stir …

Behind Bars, Beyond Means: Why Incarceration Is The Ultimate Form Of Poverty In The U.S., Samuel Bohn, Ella Paligo, Benjamin White

FHSS Mentored Research Conference

This Fulton Mentored Student Research Conference poster examines the relationship between incarceration and poverty in the United States, where currently over 2 million individuals are imprisoned, constituting 20% of the global prison population. Comprehensive analysis reveals that incarceration exacerbates poverty in the United States through the stigmatization of ex-felons and intergenerational poverty— both perpetuated by systemic exclusions. Drawing on Christian and Islamic principles, this poster highlights the universal call for justice and compassion for these marginalized individuals. The proposed reforms emphasize investment in rehabilitation programs, sentencing reform, and addressing structural inequities. Ultimately, by integrating research-based policies and collectively advocating for …

As the first study to use risk communication theory in a sports scenario while also employing corporate social advocacy as the second theoretical basis of analysis, this qualitative study is a thematic and textual analysis of 14 NBA …


Neural Correlates Of Emotion Word Processing In Bilinguals: An Fnirs Study, Daniela Andrea Ortega Manchego Apr 2024

Neural Correlates Of Emotion Word Processing In Bilinguals: An Fnirs Study, Daniela Andrea Ortega Manchego

Theses and Dissertations

Despite increasing interest in the interface between emotion word processing and bilingualism, the representation of valence during emotion word processing in the bilingual brain remains unclear. In the present study, we used functional near-infrared spectroscopy (fNIRS) to investigate the neural correlates of written emotion words in a first (L1) and a second (L2) language. Native English (16) and native Chinese (16) bilingual participants rated emotion words in their first and second language while we recorded their brain activity. Our results show distinct neural processing patterns between L1 and L2, with the former eliciting increased overall activation in the dorsolateral prefrontal …

Evaluating The Effectiveness Of Dormant Season Grazing To Reduce Cheatgrass And Its Effect On Biodiversity, Curtis L. Drake

Theses and Dissertations

Invasion of cheatgrass (Bromus tectorum L.) into sagebrush steppe communities threatens the survival of these at-risk ecosystems. One tool available to combat cheatgrass invasion is dormant season grazing. This study investigates the effectiveness of dormant season cattle grazing to reduce cheatgrass abundance in two high-elevation sagebrush steppe communities in southeastern Idaho, as well as the impact of dormant season grazing on plant species biodiversity. Our experiment utilized a randomized complete block design with four grazing treatments – ungrazed, fall-grazed, spring-grazed, and a combination of spring- and fall-grazed. We used an ANOVA standard least squares procedure to determine differences in biodiversity …


Application Of High-Deflection Strain Gauges To Characterize Spinal-Motion Phenotypes Among Patients With Clbp, Spencer Alan Baker Apr 2024

Application Of High-Deflection Strain Gauges To Characterize Spinal-Motion Phenotypes Among Patients With Clbp, Spencer Alan Baker

Theses and Dissertations

Chronic low back pain (CLBP) is a nonspecific and persistent ailment that entails many physiological, psychological, social, and economic consequences for individuals and societies. Although there is a plethora of treatments available to treat CLBP, each treatment has varying efficacy for different patients, and it is currently unknown how to best link patients to their ideal treatment. However, it is known that biopsychosocial influences associated with CLBP affect the way that we move. It has been hypothesized that identifying phenotypes of spinal motion could facilitate an objective and repeatable method of determining the optimal treatment for each patient. The objective …

Can Podcasts Reduce Affective Polarization By Combating Contextomy Via Long-Form Discussions?, Luke D. Hartvigsen Apr 2024

Can Podcasts Reduce Affective Polarization By Combating Contextomy Via Long-Form Discussions?, Luke D. Hartvigsen

Theses and Dissertations

There is a growing concern regarding political polarization in the United States, most notably the phenomenon of affective polarization, which is when polarization increases negative feelings toward those who differ politically. The current dissertation project sought to address this issue by testing a media intervention using podcasts. Podcasts allow speakers to talk for hours uninterrupted through long-form discussions, whereas other media often edit political discussions to the point of contextomy (editing and framing a quote out of its proper context). Podcasts were created for this dissertation which differed on the political message of the podcast guest (conservative vs. liberal), and …

By conducting an integrative literature review, we find that those who indicate that they are democratic educators used four major pedagogical categories including inquiry methods, artistic methods, oral methods, and student-centered methods. In the second article, we addressed the question of how professional development influences teachers' professional civic identities. In …


"Great Injustice In American Literature": African American Girlhood In Black And White Authored Children's Publications, 1887-1920, Becca Driggs Apr 2024

"Great Injustice In American Literature": African American Girlhood In Black And White Authored Children's Publications, 1887-1920, Becca Driggs

Undergraduate Honors Theses

This thesis examines the role of African American girls in creating and dismantling nineteenth-century race myths through a comparison of publications in black and white authored presses. Fictional stories published in St. Nicholas, the most popular turn-of-the-century children’s magazine, reveal that white authors, specifically Southern women, intentionally crafted narratives demeaning African American girls to cement a national racial hierarchy. Their work indoctrinated white children in racism and undermined African American legitimacy in the decades following the Civil War and Reconstruction. Concurrently, black authors recognized these attacks and in their press explored the lived experiences of African American girls to counter …

We analyzed the data using principal component analysis (PCA) and multidimensional scaling (MDS) to understand the lake geochemistry and inform Utah Lake management decisions regarding nutrients and algal blooms. We found that 1) sediments rich in phosphorus (P) act as a source for bioavailable …


Psychotherapy Client Termination Patterns And Outcomes: A Large Follow-Up Study, Including Zero-, One-, And Two-Session Cases, Adam Victor Mcdonald Apr 2024

Psychotherapy Client Termination Patterns And Outcomes: A Large Follow-Up Study, Including Zero-, One-, And Two-Session Cases, Adam Victor Mcdonald

Theses and Dissertations

Empirical research examining psychotherapy clients' post treatment outcomes for all case lengths and their reasons for discontinuing treatment is limited in the literature, particularly for shorter case lengths. Research indicates that clients with zero-, one-, and two-session case lengths are the most common in psychotherapy (Howard et al., 1986; Nielsen et al., 2016; Phillips, 1985; Phillips 1987); and yet, little is known about these clients. The purpose of this study is to better understand these termination patterns and outcomes for the most common case lengths. Outcomes were measured with the Outcome Questionnaire-45 total score (OQ-45; Lambert et al., 2004). Client …

Time Spent Jogging/Running And Biological Aging In 4,458 U.S. Adults: An Nhanes Investigation, Christina Michelle Blackmon Apr 2024

Time Spent Jogging/Running And Biological Aging In 4,458 U.S. Adults: An Nhanes Investigation, Christina Michelle Blackmon

Theses and Dissertations

Telomere length is a good index of cellular aging. Longer telomeres are predictive of longer life, and healthy lifestyles are associated with longer telomeres. This study explored the relationship between time spent jogging or running each week and leukocyte telomere length (LTL) in 4,458 randomly selected U.S. adults. The association was studied using data collected by the National Health and Nutrition Examination Survey (NHANES), and a cross-sectional design. Total weekly jog/run time was calculated from survey responses. From the minute totals, three categories were formed: <10 minutes/week, 10-74 minutes/week, and ≥75 minutes/week. Adults in the third category met the U.S. guidelines. Data were analyzed using one-way ANOVA. Partial correlation was used to adjust for differences in potential mediating factors, including demographic and lifestyle/medical factors. In the total sample, after adjusting for all the potential covariates, mean LTL significantly differed across the 3 jog/run categories (F=4.1, P=0.0272). Specifically, adults who met the guidelines via jogging and/or running had significantly longer telomeres than adults who performed no jogging/running. Adults in the middle category did not differ from the other two categories. A minimum of 75 minutes of jogging/running weekly is predictive of longer telomeres when compared to adults who do not jog or run regularly.


Error Processing In Adolescents With A Mild Traumatic Brain Injury (Mtbi): A Longitudinal Study, Tanner J. Jensen Apr 2024

Error Processing In Adolescents With A Mild Traumatic Brain Injury (Mtbi): A Longitudinal Study, Tanner J. Jensen

Theses and Dissertations

Error processing, a neural process critical to adaptive learning during adolescence, may be disrupted by mild traumatic brain injury (mTBI). Both cross-sectional and longitudinal studies of adults following mTBI indicate a variable impact of mTBI on neural correlates of error processing, including the error related negativity (ERN) and post error positivity (Pe) components of the scalp-recorded event-related potential (ERP). Existing studies of mTBI in adolescents indicate significantly decreased ERN amplitudes and nonsignificant differences in Pe amplitude between mTBI and control groups. However, no longitudinal studies of adolescents with mTBI are available to date despite the importance of these processes. We …


Investigating Which Muscles Are Most Responsible For Tremor Through Both Experimental Data And Simulation, Daniel Benjamin Free Apr 2024

Investigating Which Muscles Are Most Responsible For Tremor Through Both Experimental Data And Simulation, Daniel Benjamin Free

Theses and Dissertations

Tremor affects millions of people and many patients desire alternative treatment options to medication or neural surgery. Peripheral suppression techniques are gaining greater use, but are currently applied in a trial-and-error method. To optimize these techniques, the muscles most responsible for an individual patient's tremor need to be identified. In this dissertation, I explored two parallel paths that both could aid in identifying muscles responsible for tremor. The first method utilizies measured data and a technique (coherence) that quantifies the frequency dependent correlation between two signals. Using coherence to identify muscles contributing to tremor requires at least two parts: an …

The Persistence Of "A Simple Melody": Acceptance Of Irving Berlin's Music In The 1920s, Alina Vanderwood Apr 2024

The Persistence Of "A Simple Melody": Acceptance Of Irving Berlin's Music In The 1920s, Alina Vanderwood

The Thetean: A Student Journal for Scholarly Historical Writing

"Nobody appreciates more than I do how bad some of my lyrics are in the matter of technical details," said the 32-year-old composer Irving Berlin in 1920 during an interview with American Magazine. "Some of the biggest hits I've written were songs I was so ashamed of that I pleaded with the heads of music houses not co publish them." Yet in all of its imperfection, his music became so popular and influential that American composer Jerome Kern famously wrote, "Irving Berlin has no place in American music. He is American music." Just nine years prior to this 1920 interview, …

The evidence against the Immigration and Naturalization Service was clear. "The agent grabbed me by the arm and twisted it behind my back. He threw me against the van and held me by the arms while a second agent cook out his revolver and struck me very hard in the face, twice. I began to bleed profusely from the nose and mouth," recalled plaintiff Crosby Orantes Hernandez. "He told me that I would be placed in a cell with men, leaving me with the impression that I would be sexually molested," testified fellow plaintiff Dora Elia Estrada. Jose Sanchez Flores …


The Wolfenden Report: The Key To The English Gay Rights Movement, Ryan Hollister Apr 2024

The Wolfenden Report: The Key To The English Gay Rights Movement, Ryan Hollister

The Thetean: A Student Journal for Scholarly Historical Writing

The history of homosexuality in Great Britain is long and complicated, extending all the way back to the Roman conquest. Romans had a tradition of homosexuality, but when Rome fell, churches became the authority on homosexuality, leading to numerous movements to fight against it. King Henry the 8th of England outlawed buggery, a term for anal intercourse, in 1533, and there are suspicions chat King James had homosexual relationships, but the scope of English history cannot be fully summarized in a paper of this length. Instead, this paper will focus on the British decriminalization of homosexual practices in the 1950s …


Abraham Smoot: Complexity In Context, Molly Hansen Apr 2024

Abraham Smoot: Complexity In Context, Molly Hansen

The Thetean: A Student Journal for Scholarly Historical Writing

In 2019, a Salt Lake Tribune article described pieces of Abraham O. Smoot's slaveholding past. The article raised controversy over the administration building on BYU campus, which bears Smoot's name. After that Salt Lake Tribune article brought Smoot's negative history into a more public eye, outcry from the general public, the BYU community, the Latter-day Saint community, and the Smoot family themselves erupted. Questions like 'Why do we have buildings that honor slaveholders?' and 'Was he even a slaveholder?' and 'Do we unname or rename the Abraham Smoot Building at BYU?' were raised, and are still being asked in public …


"Hiding By Showing": Hans Holbein's The Ambassadors As A Eucharistic Tableau, Katharine Davidson Bekker Apr 2024

"Hiding By Showing": Hans Holbein's The Ambassadors As A Eucharistic Tableau, Katharine Davidson Bekker

The Thetean: A Student Journal for Scholarly Historical Writing

Liturgical cloths and hangings have been a ubiquitous part of the Eucharistic experience for Christian churchgoers for much of the Catholic Church's religious history. While often overshadowed or displaced in religious images by the drapery of individual figures, altar cloths and frontals are occasionally featured, as in the Master of the Aachen Altar's images of The Mass of St. Gregory (figs. I and 2). A similar green cloth to those in the St. Gregory images is seen in the background of Hans Holbein the Younger's 1533 portrait of The Ambassadors (fig. 3). Though much has been said about many of …


Remote Sensing Of Residential Landscape Irrigation In Weber County, Utah, Annelise Marie Capener Apr 2024

Remote Sensing Of Residential Landscape Irrigation In Weber County, Utah, Annelise Marie Capener

Theses and Dissertations

Irrigation of residential properties in urban settings is typified by small and irregular areas, many untrained water users, limited end-use metering, and differing groundcover in contrast to agricultural settings. This makes analyzing irrigation patterns to promote efficient water use challenging. Analysis of Irrigation by Remote Sensing (AIRS) combines multispectral aerial imagery, evapotranspiration data, and ground-truthed measurements to overcome these challenges. We demonstrate the application of AIRS on eight neighborhoods in West Haven, Utah, using 0.6 m National Agriculture Imagery Program (NAIP) and 0.07 m drone imagery, reference evapotranspiration (ET), and water meter data from Weber Basin Water Conservancy District (WBWCD). …

The articles included interventions specific to a unique context, interventions used in a specific context but could be easily adapted to other contexts, and generic interventions that could be applied in any context. Important themes revealed in the analysis include the importance of feedback in developing SR, the interaction …


A Review Of Existing Literature Surrounding Female Educator Sexual Misconduct In Anglo-American Classrooms, Avery Barnes, Isaac Calvert Apr 2024

A Review Of Existing Literature Surrounding Female Educator Sexual Misconduct In Anglo-American Classrooms, Avery Barnes, Isaac Calvert

BYU Education & Law Journal

A 2004 literature review commissioned by the U.S. Department of Education estimated that one in every ten students would experience sexual harassment or abuse at the hands of an educator during their time in public schools. Even more alarming, multiple studies within Shakeshaft’s 2004 review suggested that this issue goes well beyond the reported data. At that time, leading social science research estimated that only 6% of children who were victims of educator sexual misconduct reported it. With significant developments in digital communications technologies since that 2004 study, researchers in the U.S. Department of Education have estimated that the number …


Advancing Single-Cell Proteomics Through Innovations In Liquid Chromatography And Mass Spectrometry, Kei Grant Isaac Webber Apr 2024

Advancing Single-Cell Proteomics Through Innovations In Liquid Chromatography And Mass Spectrometry, Kei Grant Isaac Webber

Theses and Dissertations

Traditional proteomics studies can measure many protein biomarkers simultaneously from a single patient-derived sample, promising the possibility of syndromic diagnoses of multiple diseases sharing common symptoms. However, precious cellular-level information is lost in conventional bulk-scale studies that measure tissues comprising many types of cells. As single cells are the building blocks of organisms and are easier to biopsy than traditional bulk samples, performing proteomics on a single-cell level would benefit clinicians and patients. Single-cell proteomics, combined with mass spectrometry imaging, can be used to analyze cells in their microenvironment, preserving spatial information. We have previously used laser-capture microdissection to isolate …
