It presents the first two years of on-farm trial results on yield and quality after implementing various soil health practices on five categories of crops: corn, mixed hay, alfalfa, produce, and dryland grain. Over a two-year period, none of the soil health practices resulted …

Understanding Hydroclimate In The Contiguous United States: Roles Of Temperature Vs Precipitation And Subtropical Pacific Warming, Grace Esenam Affram

All Graduate Theses and Dissertations, Fall 2023 to Present

This study investigates the physical drivers and mechanisms of hydroclimate variability across the Contiguous United States (U.S.), using a combination of observable data, reanalysis data, land modeling, and coupled climate model experiments. One of the major findings is that the historic 2021 drought event across the Western U.S. was primarily driven by a severe lack of precipitation rather than increased temperatures. The study further finds that anthropogenic forcing has substantially increased the risk of this extreme drought by approximately 26 times relative to a world without the influence.

Additionally, the study reveals that the Pacific Meridional Mode (PMM) characterized by …

Supplementing Tannins To Increase Performance And Reduce Methane Emissions In Cows Grazing On Western Grasslands, Horacio Pedro Blanchard

All Graduate Theses and Dissertations, Fall 2023 to Present

Cattle grazing on U.S. rangelands often rely on a limited diet made up mostly of grasses. As the seasons change from spring to fall, the nutritional quality of these grasses declines, leading to less efficient digestion and higher production of methane—a potent greenhouse gas. In addition, most grass-based pastures lack beneficial plant compounds, such as tannins.

This study explored whether adding natural tannins—specifically, condensed and hydrolyzable tannins from quebracho and chestnut trees—to the diet of grazing cattle could improve how the use efficiency of nutrients and reducing methane emissions from cattle. Over two years, 24 cow-calf pairs grazed in small …

Modeling For Functional Traits In Bluebunch Wheatgrass Using Unmanned Aerial Vehicle (Uav) High-Throughput Phenotyping, Brittany L. Johnson

All Graduate Theses and Dissertations, Fall 2023 to Present

Changing climates and shifts in community composition in the Intermountain West threaten sagebrush-steppe ecosystems, impacting both plants and animals. Restoring native grasses like bluebunch wheatgrass (Pseudoroegneria spicata; BBWG) can help ecosystems resist invasive species and recover from stress and disturbances. As a native cool-season grass, BBWG is widely used in rangeland restoration for the western U.S. Breeding programs for restoration plant materials, such as seeds for ecological projects, often require years or decades of field testing while facing staffing constraints. High- throughput phenotyping (HTP), which rapidly measures observable plant traits, offers a faster solution using drones to capture time-series …

Beyond The Click: Investigating Mental Models, Targeted Attacks, And Behavioral Interventions Against Clickbait, Ankit Shrestha

All Graduate Theses and Dissertations, Fall 2023 to Present

Clickbait is misleading or exaggerated content on social media that tricks people into clicking on links by making them curious. For instance, posts that use headlines such as “This is the worst day to visit a restaurant”. These clickbait posts can lead to fake news, wrong information, and even harmful websites. Even though many people know clickbait can be risky, they often still fall for it. Existing tools to stop clickbait don’t always consider how people think, the situations they are in, or their different needs. This research looks at how people understand and react to clickbait, and develops different …

A Provable Semi-Infinite Programming Approach For Solving Dynamic Nash Games, Tyler C. Gardner

All Graduate Theses and Dissertations, Fall 2023 to Present

Many engineering problems must account for the non-cooperative decisions and actions of multiple players. These problems can be modeled within a game-theoretic framework. The approach herein is to model problems as Nash games, convert them to semi-infinite programs, and leverage provable semi-infinite algorithms to solve the original problem. A particular algorithm that leverages off-the-shelf solvers is used to solve four low-dimensional benchmark problems successfully. Two types of linear quadratic dynamic games are then investigated: ones where each player’s problem is convex and ones where at least one player’s problem is nonconvex. Within each type, variations based on information structure, communication …

Water Efficient Landscaping At Utah State University: Evaluating The "True" Value Of The Landscape Resiliency And Drought Plan, Mary Claire Jennings

All Graduate Theses and Dissertations, Fall 2023 to Present

Utah faces serious water challenges due to its dry climate, growing population, and inefficient water use. While most water conservation efforts focus on homes, businesses, and farms, state institutions like universities also play a role. As Utah’s land-grant university, Utah State University (USU) uses about 260 million gallons of water each year to irrigate its 180 acres of green space, with 92% of that water being used to irrigate grass landscapes. To promote sustainability and meet state water conservation policies, USU developed the Landscape Resiliency and Drought Plan (LR&DP) to create more drought-resistant landscapes. However, implementing water-saving strategies at state …

A Numerical Investigation Of Erection Bridging In Double-Pitched Open-Web Steel Joists, Logan Joshua Ward

All Graduate Theses and Dissertations, Fall 2023 to Present

Open-web steel joists are truss members used to support roofs and floors in steel buildings. They are commonly used because they are lightweight and inexpensive to manufacture on a large scale but have a large load carrying capacity due to their depth. Because of this depth, these joists are very unstable laterally, which is addressed by adding bridging (horizontal or diagonal) members between them to resist rotation of the joists. One of the bridging types is erection bridging, which is used to prevent a joist from buckling laterally while steel erectors are traversing it during construction.

The current erection bridging …

The Whipple operation is oftentimes considered one of the most challenging and complex abdominal operations, usually reserved for duodenal and hepatopancreatobiliary malignancies. In cases of duodenal and/or pancreatic trauma with disruption of the biliary systems, a Whipple reconstruction can be performed. Such operative traumas are rare and carry with them a high level of morbidity and mortality. This case report presents a challenging 46-day clinical course of a 22-year-old African American female, who suffered multiple gunshot wounds, resulting in severe abdominal injuries. These injuries included a grade 3 duodenal injury, grade 4 pancreatic injury, and a grade 4 renal injury. …

Sad Music Listening: What Is It Good For? An Exploratory Study Of Motivations For Listening To Sad Music, Ariel Gelfand

All-Inclusive List of Electronic Theses and Dissertations

This study sought to bolster research related to the function of sad music listening. Music listening is a common coping strategy for individuals attempting to cope with and manage different emotional states, including negative or sad moods and emotions. Research surrounding self-reported reasons or motivations for listening to sad music outlines several factors that appear to serve as mood-management strategies. However, there are discrepancies among these motivations across research, which thus far has consisted of qualitative interviews of participants. (Garrido & Schubert, 2011; Saarikallio & Ekkila, 2007; Van den Tol & Edwards, 2013). Additionally, it is unclear whether listening to …

Adiponectin-Regulated Macrophage Responses In Aspergillus Fumigatus Infection: Mechanisms Of Uptake And Killing, Sri Harshini Goli

All-Inclusive List of Electronic Theses and Dissertations

Invasive aspergillosis (IA), caused by Aspergillus fumigatus, is a life-threatening infection in immunocompromised individuals, necessitating novel host-directed therapies. Macrophages are pivotal in antifungal defense, yet their function can be dysregulated; the influence of the adipokine adiponectin (APN) on this process is not fully understood. This thesis investigated the role of APN signaling in alveolar macrophage (AM) and bone marrow-derived macrophage (BMDM) responses to A. fumigatus and assessed the therapeutic potential of the APN receptor agonist, AdipoRon. Initial studies revealed that genetic deficiency in APN or its receptors renders AMs intrinsically pro-inflammatory and significantly impaired fungicidal activity against A. fumigatus. Subsequent …

Understanding The Physical Health Associations Of Intra-Individual Variability In Life Satisfaction Among Older Adults, Frosch Y. X. Quek, Kenneth Tan, David Chan

Research Collection School of Social Sciences

It is well established that inter-individual differences in life satisfaction positively predict health, but it is less clear how intra-individual variability in life satisfaction across time could influence health, particularly across individuals with different satisfaction levels. To address this gap, we analysed a large panel dataset from a national sample of 8,674 older adults, aged 50–70 (M = 59, SD = 5.42) in Singapore who completed surveys over 53 consecutive months. Results from multi-level modelling showed an interaction between variability in life satisfaction and life satisfaction mean on physical health. Specifically, there was no association between variability and health among …

"Legitimacy, War, And The State: A Framework For Understanding Legitimation Strategies In Us Foreign Policy", Daniel Jose Palomino

Graduate Program in International Studies Theses & Dissertations

Do social norms play a role in policy maker’s foreign policy choices? What methods or strategies are effective in generating sustainable public support? In contrast to certain theories that conceive of international relations as purely divorced from social norms – be they international or domestic - I argue that the characteristic of legitimacy is critical to understanding how states construct and pursue their foreign policy. Using a methodology of historical review I examine four primary qualities of legitimation theory: Concern, Audience, Effort, and Reception; using the test case of the Americanization of the Vietnam War (1961-1965) this study will …

Service With A Smile Or Salesperson Mirroring? Understanding The Flow Of Emotional Contagion In Sales Encounters, Vinh Quoc Trong Luong

Theses and Dissertations in Business Administration

This study examines the directionality of emotional contagion in sales interactions, addressing a critical gap in understanding whether emotions flow primarily from the salesperson to the customer, from the customer to the salesperson, or bidirectionally. While prior research emphasizes customer-driven emotional flow or bidirectional alignment, this study challenges these assumptions by employing categorical Cross-Recurrence Quantification Analysis (CRQA) to assess temporal emotional synchronization in sales dialogues. Leveraging automated sentiment analysis and multi-agent AI evaluation for performance metrics, the research analyzes 166 sales interactions to quantify emotional influence dynamics. Results reveal that salespeople predominantly lead emotional exchanges, exhibiting stronger and more stable …

Applying Transcriptomics For Technology Development And Conservation In North American Marine Organisms, Cory Von Eiff

Dissertations

RNA biology is a rapidly expanding field, with many avenues of discovery among marine organisms. In this study, we analyze both mollusks and sawfish. First, we perform an evaluation of sRNA biogenesis pathways throughout Mollusca, with emphasis on the easter oyster, Crassostrea virginica. Understanding these molecules prescribes RNAi-based gene silencing approaches, benefiting genetic investigation and biotechnology. Similar to other animal groups, mollusks have conserved microRNAs (miRNAs), with some shared with ecdysozoans and deuterostomes; however, there is no evidence of an endogenous small interfering RNA (siRNA) pathway. These results suggest that long double-stranded RNA (dsRNA)-based RNAi is not appropriate for gene …

Exploring High-Dose Olanzapine For Psychosis In An Adolescent With Treatment-Resistant Schizophrenia, Shaurya Aggarwal, Shweta P Sahu, Puja Shah, Micah J Knobles

Faculty, Staff and Student Publications

High-dose olanzapine has shown efficacy in treating adult patients with treatment-resistant schizophrenia, though evidence in adolescents remains limited. This report describes the case of a 17-year-old male patient with treatment-resistant schizophrenia who showed significant clinical improvement with a supratherapeutic dose of orally disintegrating olanzapine. The patient, with a 16-month history of schizophrenia and multiple hospitalizations, presented with acute psychosis and aggression after medication non-adherence. Following failed trials of paliperidone and standard-dose olanzapine, and unable to initiate clozapine due to blood draw refusal, the patient was gradually titrated to 50 mg daily of orally disintegrating olanzapine (20 mg early morning, 30 …

Associative Coding Of Conditioned Fear In The Thalamic Nucleus Reuniens In Rodents And Humans, Tuğçe Tuna, Michael S Totty, Muhammad Badarnee, Flávio Afonso Gonçalves Mourão, Shaun Peters, Mohammad R Milad, Stephen Maren

Faculty, Staff and Student Publications

The nucleus reuniens (RE) is a midline thalamic structure interconnecting the medial prefrontal cortex (mPFC) and the hippocampus (HPC). Recent work in both rodents and humans implicates the RE in the adaptive regulation of emotional memories, including the suppression of learned fear. However, the neural correlates of aversive learning in the RE of rodents and humans remain unclear. To address this, we recorded RE activity in humans (BOLD fMRI) and rats (fiber photometry) during Pavlovian fear conditioning and extinction. In both rats and humans, we found that conditioned stimulus (CS)-evoked activity in RE reflects the associative value of the CS. …

If It Walks Like A Duck: Self-Identification, Definition, And Experiences Of Non-Traditional Doctoral Students In The Communication Discipline, Laura C. Bruns, Sara V.A. Kaufman, Ana Lisa Padron Eberline, Meredith L. Pruden, Erin Perry, Elise P. Taylor, Deborah J. Danuser

Journal of Communication Pedagogy

This study aimed to understand experiences of nontraditional doctoral students pursuing their PhD in Communication. Although the term “nontraditional student” exists in the literature (Cox & Ebbers, 2010; Stone & O’Shea, 2019), there is little consensus about demographics of nontraditional doctoral students (NTDS), nor their experiences navigating these programs. Using qualitative, thematic analysis of survey responses (n = 52), this critical mixed-method study found three themes— age, experience, and education gap—as defining identity factors, barriers, and benefits. Participants described themselves as nontraditional due to different lived experiences from graduate peers, resulting in feelings of “Otherness” within their programs. These findings …

Communicatively Enhancing Belonging By Meeting The Motivations Of First-Generation College Students In The Classroom, Miles C. Coleman, Brooke Hoffman, Angela Cirucci

Journal of Communication Pedagogy

First-generation college students’ (FGCS) experiences can be accompanied by lower senses of belonging when compared to continuing-generation college students (CGCS). This article explores some instructional communication best practices for supporting belongingness by meeting the motivations of FGCS with phrasings, framings, and designs of course content that might cultivate resonance with that which drives students. Specifically, strategies are discussed for meeting the motivations of FGCS as they might be shaped by imposter syndrome, negative affect, and orientations toward upward mobility.

Rigor And Academic (Re)Socialization: The Faculty Role In Student Success Curriculum, Kendra Knight, Stephanie Grau, Elissa Foster, Jay Baglia

Journal of Communication Pedagogy

In the post-pandemic learning era, communication faculty experience tensions among expectations for flexibility, sensitivity to students’ well-being, and our commitment to the academic rigor of our courses. These tensions, we argue, may be resolved through offering academic (re)socialization as a stand-alone element of the communication curriculum. This essay explicates the development and implementation of a for-credit workshop-style course aimed at bridging gaps in student academic capital laid bare by the COVID-19 learning crisis. “Communication Fundamentals for College Success” is a collaborative effort among six communication instructors to support practical and socio-emotional skills that undergird students’ transdisciplinary intellectual growth. We reflect …

Rethinking The Reach Of The Basic Course: Diversity And Interdisciplinarity As Catalysts For Reinvigorating The Foundations Of The Discipline, Narissra Maria Punyanunt-Carter, Sydney E. Brammer, Ryan J. Martinez
