Dropout In Couple Therapy: An Exploration Of The Trajectories Of Couples Dropping Out, Ragan A. Lybbert

Theses and Dissertations

Dropout is a problematic phenomenon which wastes community, clinician, client, and researcher resources. Clients who dropout from therapy end up the same, or worse than, those who did not seek out therapy at all. While there is a relatively deep and broad understanding of dropout from individual therapy, an exhaustive review of couple therapy dropout literature reveals a very inconsistent and non-conclusive body of research. This may stem from a lack of a consistently used theory to guide research endeavors in this important realm. Primarily, this seems to stem from treating dropout as a static event rather than a process …

Climate Change And The Global Nutrient Overload: The Microbial Response Of Extreme Waterbodies To Environmental Change, Samuel P. Bratsman

Theses and Dissertations

One of the defining characteristics of our current epoch—the Anthropocene—is modification of nutrient cycles. At regional to global scales, humans have fundamentally reshaped the availability of carbon, nitrogen, and phosphorus. These changes are particularly apparent in freshwater ecosystems, which receive surface and groundwater inputs of nutrients from agriculture, fossil fuel use, and wastewater. In this thesis, I investigated how the addition of nutrients affects microbial community and biogeochemistry in two extreme environments: the hypereutrophic shallow Utah Lake and nutrient-limited Arctic permafrost streams. In my first chapter, I used bioassay and dilution bioassay experiments to identify what factors control harmful algal …

Ducks In The Pond: Elementary-School-Age Children's Perceptions Of Standard American English, African American English, And Spanish-Accented English On Scales Of Status And Solidarity, Heather Jill Johnson

Theses and Dissertations

The literature surrounding children's language attitudes has blossomed in recent years, but little is known about modern children's attitudes toward ethnic varieties of English. In addition, little is known about what factors may influence these attitudes. Here I investigate the language attitudes of children in kindergarten through third grade. These children in South Central Idaho have considerable experience with Spanish-accented English (SPE), but very little real-world experience with African American English (AAE). White, Latinx, and biracial participants were asked to evaluate samples of Standard American English (SAE), AAE, and SPE in relation to each other on scales of both status …

Relationships Among Aa-Genome Chenopodium Diploids And A Whole-Genome Assembly Of The North American Species, C. Watsonii, Lauren Amillicent Young

Theses and Dissertations

Chenopodium quinoa Willd., an ancient Andean pseudocereal almost exclusively consumed in South America, jumped onto the global stage when Western cultures noted quinoa's advantageous nutritional profile. Quinoa seed's high protein content, nutritionally balanced amino acid profile, low glycemic index, and high fiber, vitamin, and mineral content, make it a highly sought-after 'superfood'. Pitseed goosefoot (C. berlandieri Moq.), a closely related North American species sharing quinoa's genome composition (AABB), grows across the North American continent, inhabiting diverse environments including the saline coastal soils of the Gulf of Texas and the drought-prone regions of the Southwest. Quinoa and pitseed goosefoot, along with …

Understanding And Working Through Self-Harm, Maya Wilde

Student Works

Self-harm is a coping strategy used by many adolescents dealing with mental disorders. Fifteen articles from academic journals published between 2012 and 2022 were examined. Those who struggle with non-suicidal self-injury (NSSI) experience overactivation in the fronto-limbic system of the brain, which includes the amygdala (Kaess et al., 2021). Self-harm decreases activity and stress in the amygdala and increases the amount of dopamine in the brain (Kaess et al., 2021; Reitz et al., 2015). Self-harm may be used as a way to regulate negative affect. Seeing blood might be a significant part of an episode of NSSI, but it is …

Improvement Of Ex Vivo Testing Methods For Spine Biomechanical Characterization, Aubrie Lisa Taylor

Theses and Dissertations

This dissertation contributed three main areas to flexibility testing and biomechanical characterization of human spinal segments. The first was a literature review of existing testing methodology, the second examined common spine fixation procedures, and the third developed an improved fixation method. Spine biomechanical characterization is the primary technique for assessing the healthy, diseased, and surgically treated response of spinal tissues. However, despite decades of use, no standard testing protocol or reporting methodology for flexibility testing conditions has been established. As part of the present work, a comprehensive, systematic literature review was performed, and the methods sections of 242 relevant journal …

Reporting Verb Variation Across Disciplines: An Academic Corpus Study, Grant Eckstein, Jacob D. Rawlins, Hannah Taylor, Haley Briggs, Andrea Candland, Elizabeth Hanks, Sarah Hill

Faculty Publications

Reporting verbs are used in academic writing to establish authorial voice when referencing previous research. Although the practice is widespread, inexperienced academic writers and second-language learners may struggle to select appropriate reporting verbs within their given discipline or may overuse them in ways that signal outsider status. The present study explores the distribution of reporting verbs across six disciplines in a corpus containing 270 academic research background sections (introduction and literature review). The results illustrate that disciplines vary widely in the number and type of reporting verbs used. While common reporting verbs across disciplines include argue, examine, report …

Airship Systems Design, Modeling, And Simulation For Social Impact, Daniel C. Richards

Theses and Dissertations

Although there have been oscillations in airship interest since their use in the early 1900s, technological advancements and the need for more flexible and environmentally friendly transportation modes have caused a stream of study and surge in airship development in recent years. For companies and governments to understand how airships can be incorporated into their fleets to fulfil new or existing mission types, system design space exploration is an important step in understanding airships, their uses, and their design parameters. A decision support system (DSS), Design Exploration of Lighter-Than-Air Systems (DELTAS), was developed to help stakeholders with this task. DELTAS …

The Default Network And Autism Spectrum Disorder: Characterizing Sub-Networks And Behavioral Correlates, Alyssa K. Kozlowski

Theses and Dissertations

The default network (DN), and specifically its sub-networks default network A (DN A) and default network B (DN B), has been strongly implicated in social cognition. This study examined its role in predicting social behavior, and also differences that may exist across diagnostic groups that may explain discrepancies in social cognition and behavior. One of the popular methods of study is functional connectivity, or analyzing correlated activity in the brain. Autism Spectrum Disorder (ASD) is a disorder characterized by social impairment and abnormal social behavior. To date, much of the functional connectivity research in ASD has focused on global connectivity, …

Analysis Of A Full-Stack Data Analytics Solution Delivering Predictive Maintenance To A Lab-Scale Factory, Nathan Wesley Hoyt

Theses and Dissertations

With the developments of industry 4.0, data analytics solutions and their applications have become more prevalent in the manufacturing industry. Currently, the typical software architecture supporting these solutions is modular, using separate software for data collection, storage, analytics, and visualization. The integration and maintenance of such a solution requires the expertise of an information technology team, making implementation more challenging for small manufacturing enterprises. To allow small manufacturing enterprises to more easily obtain the benefits of industry 4.0 data analytics, a full-stack data analytics framework is presented and its performance evaluated as applied in the common industrial analytics scenario of …

Midfoot Motion And Stiffness: Does Structure Predict Function?, Kirk Evans Bassett

Theses and Dissertations

In clinical settings, dynamic foot function is commonly inferred from static and passive foot measurements; however, there is little evidence that static foot structure can predict dynamic foot function during walking gait. Previous research seeking to find correlations between the two have focused primarily on sagittal plane midfoot angles even though the midfoot has triplanar motion, which misses potentially important information. Additionally, the focus on kinematics alone may miss the contributions that forces play in midfoot mechanics. To address the angle limitations, a novel Signed Helical Angle (SHA) was developed to capture the triplanar motion of the midfoot from a …

A Direct-Read, A Posteriori Golden Copy Method For Measuring Soc Cache Upsets, Evan D. Poff

Theses and Dissertations

A method for measuring system-on-a-chip (SoC) cache upsets is presented and evaluated. In contrast to methods that predict cache contents through analysis or memory access patterns, this method uses system registers to read cache memories directly, thereby creating and checking golden copies to detect individual memory upsets during operation. The test method is driven by the device under test itself and does not require a user to set or know a priori the cache contents. A bare-metal implementation of this “direct golden method” on a Zynq UltraScale+ MPSoC logged upsets in the device’s data cache, data tag, and TLB RAM …

Computational Methods To Simulate Molten Salt Thermophysical Properties, Talmage Porter, Michael M. Vaka, Parker Steenblik, Dennis Della Corte

Faculty Publications

Molten salts are important thermal conductors used in molten salt reactors and solar applications. To use molten salts safely, accurate knowledge of their thermophysical properties is necessary. However, it is experimentally challenging to measure these properties and a comprehensive evaluation of the full chemical space is unfeasible. Computational methods provide an alternative route to access these properties. Here, we summarize the developments in methods over the last 70 years and cluster them into three relevant eras. We review the main advances and limitations of each era and conclude with an optimistic perspective for the next decade, which will likely be …

The Apache Wars And The Swiss Sergeant, John Spring, Albert Winkler

Swiss American Historical Society Review

The Apache Wars were a series of conflicts that comprised the longest sequence of confrontations between a Native American Nation and the white Americans of the United States. These largely took place starting with the first US military incursions into the American Southwest in 1846 during the War with Mexico and lasted until Geronimo’s final surrender in 1886. While most of the fighting occurred in the modern US states of Arizona and New Mexico, yet much of the warfare was between the Mexicans and the Apaches dating back to the seventeenth century. Those wars were very costly in lives and …

Mapping Auditory And Vestibular Response Neurons In The Optic Tectum Of Larval Zebrafish, Erika Marks, Arminda Suli

Undergraduate Honors Theses

Cellular mapping of the sensory receptive fields of brain structures is a critical step in understanding function and dysfunction in development. Deficits in the ability to receive, process and integrate the senses leads to difficulties recognizing and responding appropriately to stimuli. To understand how the senses are integrated, it is first necessary to map the neurons receptive to inputs from individual senses. The optic tectum of zebrafish is a structure known for its homology to the superior colliculus of mammals and is a center of multisensory integration – including visual, auditory, and somatosensory stimuli. However, the microcircuitry of this important …

Baseline Biodiversity Assessment Of South Texas Small Mammals And Host-Associated Hard Ticks With No Detection Of Selected Tick-Borne Pathogens, Aleyda P. Galán, Sarah A. Hamer, Hunter A. Folmar, Tyler A. Campbell, Jessica E. Light

Western North American Naturalist

Baseline biodiversity surveys are necessary to assess organismal diversity across spatial and temporal scales. These surveys can be particularly useful for monitoring changes in organismal diversity and pathogen spread in response to climate change. Arthropod vectors such as ticks are susceptible to geographic range shifts with a warming climate, potentially resulting in the expansion of risk areas for vector-borne disease. Biodiversity data are deficient from South Texas, which is particularly concerning given the abundance of wildlife and livestock that may be important in perpetuating tick and pathogen populations. We performed a baseline biodiversity assessment of small mammals, ticks, and tick-borne …

In Their Own Words: Perspectives On Collection Weeding From Library Employees And Teaching Faculty, Dan Broadbent, Megan Frost, Gregory M. Nelson, David Pixton

Faculty Publications

Following a Science and Engineering collection weeding project of over 350,000 print items, our research team conducted interviews with 20 library employees and 19 teaching faculty involved in the project. The purpose of the interviews was to assess the interviewees’ perspectives and feelings relating to the time required to complete the project, inter- and intra- library communication, the decision-making processes, and their personal assessment of the costs and benefits of the project. The interviewees also offered their views of the overall project’s successes and areas for improvement. Drawing from a qualitative analysis of the interviews, we provide guidance for other …

Trauma And Poetry. The Case Of Primo Levi, Ilona Klein

Faculty Publications

Most North American readers have come to know and appreciate Primo Levi by his major works in prose. His The Periodic Table (1984) catapulted Levi onto the American stage of scientific-humanistic authors, having the New York Times named it among the Best Books of the Year in 1985. Instead, American readers will likely stumble upon Levi’s poetry by accident, simply because every now and then one of his poems in translation appears in print somewhere. Compared to Levi’s prose, his poems inevitably evoke a sense of unease, for their tone, their style and their content are so unlike the familiar, …

Flowunsteady: An Interactional Aerodynamics Solver For Multirotor Aircraft And Wind Energy, Eduardo Alvarez, Judd Mehr, Andrew Ning

Faculty Publications

The ability to accurately and rapidly assess unsteady interactional aerodynamics is a shortcoming and bottleneck in the design of various next-generation aerospace systems: from electric vertical takeoff and landing (eVTOL) aircraft to airborne wind energy (AWE) and wind farms. In this study, we present a meshless CFD framework based on the reformulated vortex particle method (rVPM) for the analysis of complex interactional aerodynamics. The rVPM is a large eddy simulation (LES) solving the Navier-Stokes equations in their vorticity form. It uses a meshless Lagrangian scheme, which not only avoids the hurdles of mesh generation, but it also conserves the vortical …

Language Learning Using Models Of Intentionality In Repeated Games With Cheap Talk, Jonathan Berry Skaggs

Theses and Dissertations

Language is critical to establishing long-term cooperative relationships among intelligent agents (including people), particularly when the agents' preferences are in conflict. In such scenarios, an agent uses speech to coordinate and negotiate behavior with its partner(s). While recent work has shown that neural language modeling can produce effective speech agents, such algorithms typically only accept previous text as input. However, in relationships among intelligent agents, not all relevant context is expressed in conversation. Thus, in this paper, we propose and analyze an algorithm, called Llumi, that incorporates other forms of context to learn to speak in long-term relationships modeled as …

An Iterative Numerical Method For Multiple Scattering Using High Order Local Absorbing Boundary Conditions, Jonathan Harriman Hale

Theses and Dissertations

This thesis outlines an iterative approach for determining the scattered wave for two dimensional multiple acoustic scattering problems using high order local absorbing boundary conditions and second order finite difference. We seek to approximate the total wave as it is scattered off of multiple arbitrarily shaped obstacles. This is done by decomposing the scattered wave into the superposition of single scattered waves. We then repeatedly solve the single scattering system for each obstacle, while updating the boundary conditions based off the incident wave and the scattered wave off the other obstacles. We solve each single scattering by enclosing the obstacle …
