Persuasion Strategies Employed On Instagram By Latter-Day Saint Religious Social Media Influencers, Ashton Everett Hatch

Theses and Dissertations

A content analysis of Latter-day Saint Instagram influencers is relevant to understanding what persuasive elements religious social media influencers include in their content. Observing instances that influencers persuade, establish credibility, develop trust, forge logical arguments, and engage the emotions of followers allow influencers to understand what constitutes engaging content. This study found that Latter-day Saint Instagram influencers posted emotive content that encouraged followers to continue to engage with their content, and/or endorsed another account or organizational influencer. This combination of pathos persuasion and endorsement authenticity shows that followers seek to participate in religion online as part of their regular worship.

Exploring Mesolimbic Circuitry Modulation By Opiates, Interleukin-10, And Psychostimulants, Joakim W. Ronström

Theses and Dissertations

The mesolimbic dopamine (DA) system originates in the ventral tegmental area (VTA) and projects to the nucleus accumbens (NAc) and other areas including the basolateral amygdala (BLA), prefrontal cortex, and the hippocampus. Drug use induces reward and leads to dysregulation in these brain areas and eventually to substance use disorders (SUDs). Chapter 1 introduces the mesolimbic DA system and its relationship to drug use and their relevance to each chapter. Chapter 2 explores opioid effects on BLA circuitry which is known to play a role in the emotional response including anxiety and stress in SUDs. We showed that morphine induced …

Therapeutic Benefits Of Psychedelics: Effectiveness For Addiction Treatment, Mental Health Issues, And End-Of-Life Care, Emma Roberts

Student Works

As more research is done, psychedelics are increasingly recognized as a viable option for addiction treatment, mental health issues, and end-of-life care. Studies have hit roadblocks in the past due to the stigma surrounding psychedelics that formed in the 1960s. Since then, regulations have loosened, and psychedelic therapy has become a possible alternative for those who do not find their current treatments effective (Al-Harbi, 2012, as cited in Gardner, 2019; Gardner, 2019). Psychedelics can help individuals abstain from addictions (Sharma et al., 2023). Additionally, psychedelics can be a viable treatment for mental illnesses (Nygart et al., 2022) and can be …

Improving Wifi Sensor Network Security Through Unassociated Device Communication Using Wireless Latency Shift Keying, Jacob Edward Johnson

Theses and Dissertations

IEEE 802.11 (WiFi) only has two modes of trust--complete trust or complete untrust. The lack of nuance leaves no room for sensors that a user does not fully trust, but wants to connect to their network, such as a WiFi sensor. Solutions exist, but they require advanced knowledge of network administration. We solve this problem by introducing a new way of modulating data in the latency of the network, called Latency Shift Keying. We use specific characteristics of the WiFi protocol to carefully control the latency of just one device on the network. We build a transmitter, receiver, and modulation …

Characterization Of Cellular Metabolism Regulation By The Transcription Factor Centromere Binding Factor 1 (Cbf1), Spencer Ellsworth

Theses and Dissertations

Centromere binding factor 1 (Cbf1) is a transcription factor that controls the transcription of many genes involved in cellular respiration and lipid biogenesis and, as such, has been associated with hypolipidemia in humans. It is a known substrate for PAS kinase, which phosphorylates Cbf1 and alters its activity. Our hypothesis is that this phosphorylation affects the genes it regulates and the DNA motifs it binds to, perhaps due to different transcription complexes being formed. In this study, we conduct a chromatin immunoprecipitation in Saccharomyces cerevisiae to determine what genes and DNA motifs Cbf1 binds to in its wild type versus …

Distinguishing Between Symptom Presence And Severity Using A Two-Part Sequential Model, Luiza Ferreira Pradera

Theses and Dissertations

Most symptom measures either implicitly or explicitly distinguish between symptom presence and symptom severity. For example, item 2 on the PHQ-9, a commonly used measure of depressive symptoms, asks respondents to rate how much they have been 'feeling down, depressed, or hopeless.' The response options are 0 (Not at all), 1 (Several Days), 2 (More than half the days), and 3 (Nearly every day). Answering 0 indicates that the symptom is not present, and any response greater than 0 suggests the symptom is present. Higher values indicate higher severity of the symptom. Although the response options distinguish between symptom presence …

Multifunctional And Moisture Tolerant Zinc-Based Mono- And Bi-Metallic Metal-Organic Framework (Mof) Thin Films, Emmanuel Agbata

Theses and Dissertations

Many applications of metal-organic frameworks (MOFs) are highly dependent on their structures. The type and consistency of structure inform their properties. Zinc-based MOFs are applicable in different fields because of the low toxicity of zinc materials and are therefore also useful for catalysis. While MOF-5, a zinc-based MOF with carboxylate linkers is moisture intolerant, a variant of this is moisture tolerant. The introduction of a nitrogen-based linker in the zinc MOF which renders the structure moisture-tolerant. This material has not been explored as much, despite its multifunctional properties. Furthermore, the growth of Zn-based bimetallics of this MOF has not yet …

Quality Of Life Outcomes Among Female Student-Athletes: Exploring The Role Of Coach-Athlete Relationships, Ashley Renee Kernan

Theses and Dissertations

The National Collegiate Athletic Association (NCAA) first integrated into collegiate athletics in 1906 with the goal to govern burgeoning sports activities. More than 1,098 colleges and universities participate in the NCAA and have sports teams on their campuses. Although NCAA athletics has gained popularity through the years, much of the research and education has focused on men's sports in the NCAA, thus ignoring the sharp increase of women participating in NCAA. This increase came after Title IX was implemented and now almost half of student-athletes in Division I sports are female. While some conducted research includes female student-athletes in the …

Modified Coulomb Approach For Squat Silos, Mitchell Cade South

Theses and Dissertations

Traditional methods for calculating lateral pressures in silos, such as Janssen's Method and Coulomb's Method, have limitations due to the underlying assumptions of each methodology. This research investigates an approach which adapts Coulomb's Method to account for the cylindrical geometry of silos. The Silo Wedge Method (SWM) distinguishes between two cases based on the aspect ratio (height/diameter) of the silo. Comparative analysis reveals that the SWM accurately matches Coulomb's Method for linear retaining walls when the silo aspect ratio approaches zero. As the aspect ratio increases above 0.25, the SWM exhibits behavior similar to Janssen's Method. This suggests a potential …

Sustainability In Civil And Construction Engineering, Connotations, Paradigms, And Perceptions, Xiaomei Wang

Theses and Dissertations

Over the last four decades, the concept of sustainability has evolved significantly, gaining prominence since the Brundtland report in 1987. Operating at the intersection of built and natural environments, Civil and Construction Engineering (CCE) projects and designs inherently impact the natural surroundings. In this context, the concept of sustainability serves not only as a guiding principle to mitigate depletion but also as a pathway to achieving balance among diverse societal needs so every creature can survive and thrive. Despite considerable efforts in this domain, the definition of sustainability within the CCE discipline remains elusive. Paradoxically, the popularity and vagueness of …

Development Of Zr(Iv) Mof-Enabled Nerve Agent Electrochemical Hydrolysis Sensors, Tyler James Marlar

Theses and Dissertations

Nerve agents are acetylcholinesterase inhibitors and among the most toxic chemical warfare agents ever synthesized. Detection of these chemicals is critical for the protection of populations and strategic resources. G-series nerve agents are volatile compounds. V-series nerve agents are persistent phosphonothioate compounds. Persistent nerve agents do not readily volatilize and can contaminate environmental resources for extended periods. While nerve agents are inherently non-electroactive, they can be hydrolyzed to electroactive products compatible with electrochemical sensing. Zr(IV) MOFs are next-generation nanoporous materials, which have been shown to rapidly catalyze nerve agent hydrolysis. In this work, the catalytic processes of MOF-808, a specific …

These techniques are deeply connected to the land and are essential to my identity as an artist …

Studio As Laboratory: Prioritizing Artistic Fluency Through The Morphogenesis Of Paper, Jeannette Lina Neal

Theses and Dissertations

This paper describes a curriculum designed to examine relationships between artistic fluency in middle school art classrooms, and a robust year-long paper curriculum. A sustained focus with one material, such as paper, combined with relevant artists and investigative skills activities was designed to increase artistic fluency during a time when students often experience a decline in identity and confidence. Concerns with the U-curve theory suggest that many factors affect the continuity of art during these crucial years of school. Educational standards of the Reggio Emilia Approach can be applied to secondary education, encouraging both students and educator to create dynamic …

Developing An Artistic Self In Preservice Elementary Teachers: A Studio Art Curriculum To Promote Art Integration, Karilee D. Park

Theses and Dissertations

With the continual use of standardized testing, teaching art in schools, particularly elementary schools, often falls to generalist teachers with little to no experience in art. While art can be integrated into daily curriculum for deeper and lasting learning, without the proper training or support, generalist teachers are left to implement art as they encountered it in the past, if at all. Artistic anxiety and culturally misappropriated artistic experiences result in the arts being used inefficiently or avoided completely. Creating a curriculum for preservice elementary generalist teachers, I explored art integration through developing artistic confidence, skill, and identity for 16 …

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 …

Sometimes Windows Break, Samantha Snyder

Theses and Dissertations

The sensation of detachment and reclusion frequently gives rise to an uncanny and dreamlike space. Enveloped within this dimension, the quirks of memory become a fragile lifeline to bygone, intangible ideas of reality. Fixated on this threshold, my artistic explorations in print, collage, and assemblage navigates these elusive realms, rendering fragmented and distant shapes and figures in stark contrast to elements that evoke an eerie sense of familiarity. In this manner, my work invites viewers to embrace the disconcerting and unsettling aspects of the in-between, all the while establishing an unsettling connection to reality through the lens of nostalgic objects …
