Leveraging Natural Variation In Yeast To Understand Susceptibility Differences In Parkinson’S Disease, Julio Andres Molina Pineda

Graduate Theses and Dissertations

Parkinson’s Disease (PD) is a neurodegenerative disorder that causes countless suffering around the world. Both forms, familial and sporadic, have been associated with the misfolding and cytotoxicity of α-synuclein, an otherwise non-pathogenic protein suspected to have various roles in the normal maintenance of the central nervous system. Model organisms have emerged as great vessels to uncover the cellular and molecular mechanisms that shape α-syn biology, and great strides have been made to understand it. Yet, it is still unclear why some individuals are affected by α-syn toxicity, while others not so much. Since it’s extremely complicated to study and probe …

Findings indicate that rural libraries serve as pivotal cultural coordinators and community hubs, positively affecting youth engagement …

Victims Of Stage And Screen: Parasocial Savior Rhetoric And Coded Social Critique At The Convergence Of Celebrity & Conspiracy Cultures, Amy Whiteside

Graduate Theses and Dissertations

This thesis offers a critical rhetorical analysis of what I term parasocial savior conspiracy theories , a unique genre of conspiracy narrative that portrays a public figure as victimized and allows their fans to step into a savior role through their advancement of the conspiracy theory. These narratives, I argue, are both catalyzed by and further insulative to a fan’s parasocial relationship with the public figure in question. Herein, the celebrity acts as a vessel of projection for their fans’ anxieties about control, allowing them to displace their agency panic onto a beloved external party and critique factors that seem …

Insights From Automated Mineralogic Analysis Of Modern Sand, Quinten Jones

Graduate Theses and Dissertations

Methods for determining and categorizing the modal compositions of sand and sandstone have long been a subject of debate in the field of sedimentary geology. Point counting is the most commonly used technique for determining modal compositions from petrographic slides, which are then categorized based on relative proportions of quartz, feldspar, and rock (or lithic) fragments. However, this approach fails to adequately preserve relevant textural data, such as grain size and sorting, which play an important role in diagenesis and in influencing reservoir quality. Additionally, the categorical nature of point counting results in a lack of specificity and loss of …

The Rhetorical Use Of The Lower Classes In Three Primary Accounts Of The First Crusade, John Hannon

Graduate Theses and Dissertations

This study analyzes the rhetorical use of the lower classes in three primary accounts of the First Crusade: Albert of Aachen, the Gesta Francorum, and Raymond of Aguilers — specifically with an eye towards the proper maintenance of the order of society through everyone performing their assigned role. Through a close reading of these three texts this study demonstrates how the three authors engage with and uphold versions of the idealized three orders model of medieval society. Though there is nuance between each source, broadly, each of the authors presents the lower classes as a force that needs to …

This study will analyze the 2022 HPAI event in the United States regarding the regionalization of restrictions imposed by trading partners accounting for trade agreements executed. The examination of …

The Future Of Fashion: A Systematic Literature Review On Consumer Willingness To Pay For Green Apparel, Emma Clark

Graduate Theses and Dissertations

In recent years, consumers have become highly aware of the environmental impact of their purchases, specifically of apparel products. Accordingly, apparel brands have increasingly focused on enhancing the sustainability of their product offerings to attract environmentally conscious consumers and elevate their brand image (Dangelico et al., 2022). Furthermore, most sustainably produced products are priced higher for consumers compared to standard alternatives (Elmanadily & El-Deeb, 2022). Research has shown that consumers can accept higher prices for products that do less harm to the environment (Gomes et al., 2023), but it has yet to be determined in which cases this is consistently …

Evolutionarily Conserved Functions Of The Gene Frazzled In Midline Axon Guidance In Drosophila Melanogaster And Tribolium Castaneum., Piyasi Ghosh

Graduate Theses and Dissertations

Axon guidance in bilaterians is often controlled by various signaling pathways in the nervous system, which determine the fate of the axons if they cross the midline or not. One such pathway involved is the ligand-receptor pair Netrin (Net) and Frazzled (Fra), which is also known as the attractive pathway that promotes midline crossing axons in insects and other bilaterians. Orthologs of the pathway ligand Netrins and their receptors Frazzled [Fra] in insects and Deleted in Colorectal cancer [DCC] in vertebrates are widely conserved in bilaterians. How well these regulatory roles of the protein are conserved is poorly understood. In …

Sibling Groups And Family Adaptability And Cohesion Among Emerging Adult Women, Julianne M. Post

Graduate Theses and Dissertations

This study examined how sibling group size is related to family adaptability, cohesion, and individual resiliency outcomes during emerging adulthood. Using Bowen's Family Systems Theory and Olson's Circumplex Model, the research investigates sibling subsystems as sites where systemic imbalances are first experienced within families. Data from 124 college students revealed that larger sibling groups were associated with marginally higher disengagement and chaos resulting in decreased perceived social support, suggesting resiliency implications for youth growing up within larger families. While sibling size didn't directly predict mental health, family dynamics significantly mediated the relationship between sibling composition and resiliency outcomes. Demographic factors …

Koszul Cohomology Of Canonical Products, Alexander Scott Duncan

Graduate Theses and Dissertations

In this thesis, we give a complete classification of the Koszul cohomology groups K_p,₁(C, B, ω_C ⊗ B) on a smooth curve C of genus g ≥ 2 with B p-very ample. Such a classification in the case B = ω_C has been incomplete until [5]. The classification follows easily from our main result which precisely calculates K_p,1(C, B, B ω_C ⊗ B) in terms of h⁰(C, B). This result also handles the case B = ω_C. A straightforward …

Bacterial Chondronecrosis With Osteomyelitis In Broiler Chickens: Experimental Lameness And Additive Probiotic Treatments, Amanda Anthney

Graduate Theses and Dissertations

With the global population already surpassing 8.2 billion and expected to reach 9.7 billion by 2050, the poultry industry has seen a surge in demand due to its unmatched efficiency and affordability for consumers across the globe. Selective breeding and quality nutrition developments since the industry's commercialization have allowed producers to grow broilers up to 7 pounds by market age. While this extraordinarily efficient process has allowed quality poultry products to be available worldwide, the modern-day broiler has developed a multitude of musculoskeletal issues. Due to the lack of integral skeletal development to match the rapid production of muscle tissue, …

Literary Postcritique And American Transcendentalism: Helping Students Practice Community-Building By Rewilding Literature In The Classroom, Tate Aldrich

Graduate Theses and Dissertations

Literary postcritique is an emergent theoretical approach to literature that has elicited skepticism among many in academia because of its central claim that their unchecked overreliance on suspicious and symptomatic reading styles is diminishing the pedagogical potential of our reading together. To restore this potential, Rita Felski, a champion of literary postcritique, suggests adopting an aesthetic reading style, a mid-level interpretation that neither indulges in the formalists’ habits of close scrutiny nor in the cultural critics’ wider lens of political and social contexts. In The Limits of Critique and Hooked, Felski argues that an aesthetic reading style can develop …

Application Of Ordinal Regression Models To Acquired Stress Resistance In Wild Strains Of Saccharomyces Cerevisiae, Carson Stacy

Graduate Theses and Dissertations

This thesis explores the application of ordinal regression to the analysis of semi-quantitative growth assays often used when comparing fitness for different strains of the model yeast Saccharomyces cerevisiae. For stress survival assays, yeast stress resistance is measured using an ordered survival score that ranges from 0 (no growth) to 4 (confluent growth). Traditional approaches to analyze this type of data either treats data as a nominal categorical variable or as a continuous numerical variable. These approaches risk loss of information or violation of testing assumptions. In contrast, cumulative logit ordinal regression uses the information contained in the order …

Graduate Theses and Dissertations

Climate change-induced drought stress is a significant constraint on global rice (Oryza sativa L.) production, threatening food security. This study evaluated the drought resilience of 15 diverse rice genotypes from the USDA mini-core collection under field, greenhouse, and osmotic stress conditions. Field trials assessed reproductive-stage drought tolerance based on panicle length (PL), number of spikelets per panicle (NSP), and spikelet sterility (SS). Greenhouse experiments examined moisture retention at the vegetative stage. Significant genotypic variation was observed, with genotypes 310724, 310779, 311181, 311603, 311793, and Vandana exhibiting drought tolerance through stable PL and SS. Additionally, genotypes 310100, 310428, 311255, N22, …

The Relationship Between Attention Deficit Hyperactivity Disorder And Problematic Internet Usage In Lgbtq+ Adults, Kayli Nicole Heigelmann

Graduate Theses and Dissertations

This thesis explores how LGBTQ+ adults who experience attention deficit hyperactivity disorder (ADHD) symptomology perceive and navigate potential problematic Internet usage (PIU). Utilizing a qualitative, phenomenological approach, twelve participants were interviewed to gain insight on how neurodivergence, queer identity, and Internet engagement intersect. Findings revealed two overarching themes: 1) the interplay between PIU, ADHD, and sexual/gender diversity, and 2) the meaning of the Internet for individuals with intersecting minority identities. Participants widely endorsed the Internet as an important space for identity negotiation, community, and affirmation for their multiple minority statuses, but acknowledged their vulnerability to the Internet’s attention-capturing mechanisms, reporting …

Independent trials …

Fergus Of Galloway: A New Translation For A New Audience, Emily J. Aguayo

Graduate Theses and Dissertations

My dissertation focuses on one text – Li romanz de Fergus – an Arthurian romance composed in Old French in the early thirteenth century by a mysterious author named Guillaume le Clerc. I have learned as much as I can about this romance and have looked at it from every angle possible. The scope of my research is narrow and deep because it focuses on one text, its author, and its subject matter. I have created a new theory about the identity of the author, Guillaume le Clerc, based on historical documents such as the Acts of Lordship from Scotland, …

Door - To - Door Summer Sales And Other Summer Employment: A Cost And Benefit Analysis, Jentrie Gilliland

Undergraduate Honors Capstone Projects

Door-to-door summer sales is heavily marketed to college students, especially on university campuses in Utah. These employment options are marketed as having high financial rewards while giving students the opportunity to develop their professional skills. In this study, I examine whether these expected rewards are delivered and if door-to-door summer sales is a viable position for college students in comparison to other summer employment. Specifically, I focus on the financial benefits and skills gained from both job types as well as determinants for students who participate in door-to-door summer sales versus other summer employment. My findings indicate that there is …

Limit Theory For Local Polynomial Estimation Of Functional Coefficient Models With Possibly Integrated Regressors, Ying Wang, Peter C. B. Phillips

Research Collection School Of Economics

Limit theory for functional coefficient cointegrating regression was recently found to be considerably more complex than earlier understood. The issues were explained and correct limit theory derived for the kernel weighted local level estimator in Phillips and Wang (2023b). The present paper provides complete limit theory for the general kernel weighted local th order polynomial estimators of the functional coefficient and the coefficient derivatives. Both stationary and nonstationary regressors are allowed. Implications for bandwidth selection are discussed. An adaptive procedure to select the fit order  is proposed and found to work well. A robust -ratio is constructed following the new …

The Backdrop Of Leadership: How Environmental Awe Influences Charisma Attributions, Jack Mcguire, Nicolas Bastardoz, Leonie J. Hentrup, David De Cremer, Jochen I. Menges

Research Collection Lee Kong Chian School Of Business

Charisma is often attributed to leaders based on how they look, talk, and behave. Yet very little is known about the role of the physical environment in influencing attributions of leader charisma. The role of the physical environment is crucial because leaders inevitably occupy physical spaces that vary across contexts. In this research, we find that the grandeur of the physical environment, specifically in its ability to induce awe, enhances attributions of charisma for leaders who are not already known to be charismatic. First, in a field experiment, we show that a real business leader is attributed with more charisma …

Voting For Winners And Losers In A Hybrid Regime: How Thailand's 2023 Election Shaped Voter Opinion, Jacob Ricks, Allen Hicken

Research Collection School of Social Sciences

Research in Western Democracies suggests voting has substantive impacts on how one feels about democracy and state institutions. Voting for winners leads to positive feelings while voting for losers has the opposite effect. How, though, do voters interpret electoral results in a system prone to authoritarian intervention? Thailand's 2023 election offers a unique opportunity to examine how voting in a hybrid regime can impact voter opinion. Using a pre- and postelection survey, we demonstrate that, like elections in democracies, an election in a hybrid regime can have a significant impact on voter opinions. When pro-democracy voters win an election in …

Oscar: Object Status And Contextual Awareness For Recipes To Support Non-Visual Cooking, Franklin Mingzhe Li, Kaitlyn Ng, Bin Zhu, Patrick Carrington

Research Collection School Of Computing and Information Systems

Following recipes while cooking is an important but difficult task for visually impaired individuals. We developed OSCAR (Object Status Context Awareness for Recipes), a novel approach that provides recipe progress tracking and context-aware feedback on the completion of cooking tasks through tracking object statuses. OSCAR leverages both Large-Language Models (LLMs) and Vision-Language Models (VLMs) to manipulate recipe steps, extract object status information, align visual frames with object status, and provide cooking progress tracking log. We evaluated OSCAR’s recipe following functionality using 173 YouTube cooking videos and 12 real-world non-visual cooking videos to demonstrate OSCAR’s capability to track cooking steps and …

Robust Statistical Techniques For Operational Maintenance Of The 10.7 Cm Solar Radio Flux, Daniel A. Brandt, Erick F. Vega, Brian Thelen

Michigan Tech Publications

The F10.7 solar radio flux is a critical quantity for operational space weather nowcasting and forecasting, where it is routinely used as a driver for coupled atmospheric models to estimate a variety of important quantities such as the neutral atmospheric density. Although there have been several successful developments in the way of parametric modeling to ensure F10.7 coverage during outages (often using the sunspot number or radio flux observations at neighboring wavelengths), these developments have refrained from employing comprehensive cross-validation schemes to ensure model generalizability, and can benefit from recently-developed techniques for modeling nonlinear phenomena. We present an approach that …

Symbiotic International Law: Combatting Uyghur Forced Labor, Preston Jordan Lim

Utah Law Review

Since 2017, the Chinese government has launched a campaign of repression against the Muslim Turkic minorities of Xinjiang, a region located in China’s Northwest. While most scholars have focused on the mass internment of Uyghurs and other minorities, this Article highlights an under-discussed aspect of China’s campaign: the construction of a sophisticated forced labor system. Minority forced labor supplies key sectors of the global economy—from the automotive to the energy sectors—and allows Chinese companies to outcompete foreign firms. The unprecedented scope and sophistication of what I term the “modern Xinjiang forced labor system” imperils the very future of the international …
