Introgression Or Incipient Speciation? Using Geometric Morphometrics And Gene Expression To Characterize Mouth Development In Larval June Sucker And Utah Sucker, Peter C. Searle

Theses and Dissertations

Understanding how biodiversity evolves is a major goal in evolutionary developmental biology because changes in developmental processes are tightly linked with evolutionary diversification. Heterochrony--alteration to the rate or timing of development--can significantly alter the appearance of descendant species. Heterochronic shifts in gene expression and associated morphological change may explain the morphological divergence between the threatened June sucker (Chasmistes liorus) and the sympatric Utah sucker (Catostomus ardens) in Utah Lake, UT, USA. June sucker are endemic to Utah Lake and have subterminal mouths adapted for pelagic feeding, while Utah sucker (Catostomus ardens) have ventral mouths adapted for benthic feeding. As larvae, …

Futurist Art And Touch: Dinamismo Plastico, Tattilismo, Polimaterismo, Molly J. Everett

Theses and Dissertations

This thesis considers the Futurist engagement with touch, primarily through the artwork and writing of four Italian artists: Umberto Boccioni (1882–1916), F. T. Marinetti (1876–1944), Benedetta (Cappa) Marinetti (1897–1977), and Enrico Prampolini (1894–1956). Informed by childhood education, art theory and aesthetics, and perceptual psychology, these Futurists embraced tactility as a vehicle for avant-garde invention.

Pioneers Of Evacuation, Pioneers Of Resettlement: The Photographic Archive Of The Japanese American Incarceration And The Settler Colonial Imaginary, Christina Hobbs

Theses and Dissertations

This thesis reexamines the photographic archive of the Japanese American incarceration during World War II produced by the US government, arguing that these images “restage” the evacuation, incarceration, and resettlement periods through a settler colonial “pioneer” mythology, thereby obscuring the precarity of Japanese Americans' racial positionality between “settler” and “native.”

Prosodic Modeling For Hymn Translation, Michael Abraham Peck

Theses and Dissertations

Prosody is known in linguistics as the "suprasegmental" features of language such as syllable stress and intonation. It is also known in the fields of poetics and musicology with alternate definitions and modeling practices. Concepts of prosody are further compounded when considering prosodic phenomena throughout the languages of the world. While the resulting lack of a universal concept of prosody may be tolerable in such a variety of paradigms, there is one paradigm that requires a unified model of prosody. This is the paradigm of hymn translation, which requires prosodic features to align not only musically, poetically, and linguistically, but …

External Laryngeal Oscillation And Aerodynamic Measures Of Voice Onset: A Translational Study, Erik Mcleod Christensen

Theses and Dissertations

The purpose of this study was to examine external laryngeal oscillation and its potential effects on phonation threshold pressure (PTP; cm H2O) and phonation threshold flow (PTF; L/sec). Measures of PTP and PTF have inherent limitations due to the nonlinear nature of phonation, influencing their clinical and experimental utility. This is true particularly for tracking relatively small changes in voice function because variability in the measure itself can be larger than that resulting from voice change. Elevated PTP and PTF are associated with a variety of voice disorders and correlate with self-reported vocal effort and fatigue. Prior studies involving silicone …

Abm Simulation Model Of A Pandemic For Optimizing Vaccination Strategy, Gibeom Park

Theses and Dissertations

This study presents a process-oriented hybrid model for individuals' immune responses and interactions involving vaccination to describe the trend of contagious disease and estimate the future societal cost. The model considers "recovery" as a non-absorbing state and incorporates various infection stage states including two symptomatic states. To model contagiousness to be consistent with the current pandemic and include that the spread of a disease depends on the mobility of people, we developed an Agent-Based Simulator that fitted to the particular model used in this study and can test various what-if scenarios. We improved the simulator considerably by appying data structures …

The Association Of Psychotherapist Cultural Humility And Client Experiences And Outcomes In Psychotherapy: A Meta-Analysis, Lisa Michelle Scott

Theses and Dissertations

Psychotherapist multicultural competence has been given increasing attention in the field of psychology since the 1970s. However, individuals and communities who are Black, Indigenous, or People of Color are still less likely to attend psychotherapy and often drop out earlier than White clients. These trends highlight the importance of the ongoing research on therapist multicultural competence. There are many multicultural competencies, however, the current study focuses on therapist cultural humility. Specifically, we systematically searched all the current research on the association between cultural humility and client experiences and outcomes in therapy. Our literature search yielded eight studies that met our …

Effects Of A High School Yoga Program On Student-Reported Stress, Resilience, And Academic Outcomes, Stephanie Martha Vance

Theses and Dissertations

High school yoga programs are gaining popularity throughout the United States. The many perceived benefits of such programs among adolescent groups have shown promising outcomes. This mixed-method evaluation of a high school yoga program aims to evaluate the effects of the program on student-reported stress, resilience, and academic outcomes. Program participants include high school students in yoga classes (n = 61) and comparison classes (n = 37), who completed pre- and post-measure surveys along with social validity measures. Overall findings showed a decrease in stress levels among yoga students compared to comparison students, which approached statistical significance, no significant differences …

To What Degree Does Martial Quality Predict Longevity? A Meta-Analysis Of Prospective Studies, Rachel E. Jensen

Theses and Dissertations

Strong social relationships consistently predict the quality of both physical and mental health. Society commonly recognizes the marriage relationship as one of the most committed, enduring relationships. While marital status alone can strongly predict health, it appears that moderating factors exist in this association. The quality of one's marriage can have a greater effect on health than marital status alone. We conducted a meta-analysis examining the strength of the influence that marital quality has on physical health, specifically indicated by mortality rates. To identify relevant articles, we searched multiple online databases (Embase, Psycinfo, Family and Society Studies Worldwide, and Academic …

The Role Of Social Response To Disclosure In Relgious And Spiritual Coping And Recovery From Sexual Assault, Megan Wolfe

Theses and Dissertations

Many factors can discourage survivors of sexual assault from reporting their assaults. Even those survivors who disclose, their reporting experiences may not leave them feeling empowered or that they have received adequate support to begin the healing process after disclosure. Using a mixed methods approach, we examined the relationship between religious and spiritual coping strategies, the experience of social disclosure, and symptoms of posttraumatic stress disorder (PTSD) and depression using confirmatory factor analysis (CFA) and structural equation modeling (SEM). We further used qualitative data examining the ways that participants used religious/spiritual coping strategies in response to the trauma of sexual …

Interference Between Speaking And Computer Tasks And Their Effects On Physiologic Arousal, Tiana Walker Bateman

Theses and Dissertations

This study examined the effects of concurrent speech and computer tasks on each other and on measures of physiologic arousal in 30 young adults. Physiologic measures included galvanic skin response, heart rate, and heart rate variability. Participants completed a speech-only task, two computer-based tasks, and combined speech and computer-based tasks. Participants spoke for 60 seconds on a procedural discourse prompt. Acoustic measures included the mean and standard deviation of intensity and fundamental frequency as indices of prosody, speaking time ratio to reflect pausing, and speech rate. The primary computer task (with two levels of difficulty) involved making formatting changes to …

My method combines synthetic control and difference-in-differences regressions.

How Federal Pollution Discharge Permits Affect U.S. Water Quality: A Study On Concentrated Animal Feeding Operations, Cloe C. Mueller

Theses and Dissertations

This paper uses difference-in-difference regression models to examine how state-level pollution discharge permits on concentrated animal feeding operations affect U.S. water quality. I ultimately deem the permitting to be ineffective at improving water quality, calling attention to the need to re-evaluate the ``socially optimal level of pollution."

Catharanthine Modulates Mesolimbic Dopamine Transmission: A Potential Treatment For Alcohol Use Disorder, Benjamin M. Williams

Theses and Dissertations

Catharanthine is derived from the Catharanthus roseus plant and is an analog to ibogaine, a drug that reduces opioid and alcohol withdrawal symptoms and decreases drug self-administration in both animals and humans. Catharanthine has promise to be an alternative pharmacological treatment for addiction without the adverse side effects associated with ibogaine. The objective of this study was to evaluate catharanthine’s effects on dopamine (DA) transmission in the mesolimbic DA system as well as determine its effects on both ethanol withdrawal induced anxiety and drug-seeking behaviors in mice. We hypothesized that catharanthine would inhibit evoked DA release in the nucleus accumbens …

Elucidating The Relationship Between Self-Reported Disability And Functional Movement In Individuals With Chronic Low Back Pain, Kelsey Ampudia Clark

Theses and Dissertations

INTRODUCTION: Low back pain (LBP) is often exacerbated by movement and, during functional movements, people with LBP tend to inherently modify their posture and movement patterns to avoid aggravating their pain further. Therefore, analysis of spinal movement in people with LBP is necessary and may lead to the identification of movement-based clusters for optimal treatment. PURPOSE: The overall purpose of this study was to investigate how movement patterns in people with chronic LBP relate to their subjective level of pain-related disability. First, we determined which spinal movements best discriminate between people with chronic LBP and asymptomatic controls; second, we ascertained …

The Discovery Of Novel 14-3-3 Binding Proteins Atg9a And Ptov1 And Their Role In Regulating Cancer Mechanisms, Colten Mitchell Mcewan

Theses and Dissertations

14-3-3 proteins are among a family of phospho-binding proteins that are known to regulate many essential cellular mechanisms. By binding to sites of phosphorylation, 14-3-3s are integrated into multiple signaling pathways that govern critical processes, such as apoptosis, cell cycle progression, autophagy, glucose metabolism, and cell motility. These processes are crucial for tumorigenesis and 14-3-3 proteins are known to play a central role in facilitating cancer progression. In this study, my colleagues and I discover two novel 14-3-3 interacting proteins, ATG9A and PTOV1, that are both vital to essential cellular functions and describe various mechanisms that these two proteins regulate. …

Investigations Into Pressure Profile And Pressure Control In Wrist-Worn Health Monitoring Devices, Roger Mcallister Black

Theses and Dissertations

To aid in the design of future wearable health devices (WHDs), contact pressure between the distal forearm (wrist) and two different wrist-worn devices was investigated in this work. The first device included eight force sensors arranged in series along the length of a wristband to measure the pressure profile. The band also included a tensioner device for manually tightening the band while on a wrist. Testing was done on dummy wrists and the results were statistically significant supporting the hypothesis that areas of the wrist with lower radius of curvature will experience higher contact pressures generally and a faster rate …

Gendered Differences In The Effects Of Adverse Childhood Experiences On Adolescent Substance Use, Emley A. Holcombe

Theses and Dissertations

Adolescence is a high-risk period for substance use, and the prevalence of adolescent substance use is a public health concern. Contributing factors for adolescent substance use are adverse childhood experiences (ACEs). ACEs are potentially traumatic childhood events that have negative associations with health and risk behaviors. The purpose of this study is to examine how the accumulation, timing, and duration of early ACEs (by age 5) impacts adolescent substance use. In addition, this study examines differences in these relationships by gender. Data from the Fragile Families and Child Wellbeing Study (FFCW) were used for the logistic regression analyses. The results …

Acceptance Finds A Way: How To Teach And Use Evolution's Explanatory Power, Daniel George Ferguson

Theses and Dissertations

The theory of evolution is the central combing theory that brings together all the tenets of biology that bring about a solid understanding of life. It is also one of the most controversial scientific theories of all time and is widely rejected by about 40% of the general public in the United States. One of the biggest reasons for low evolution acceptance is the perceived conflict between evolution and religious beliefs. Educators and researchers have been working hard to improve how we teach evolution in the classroom; some methods, such as focusing on evolution knowledge, have shown to be mixed. …

Help-Seeking Experiences As An Individual With Suicide Ideation: A Qualitative Study About Seeking Help For Suicide Ideation, Makaela H. Caldwell

Theses and Dissertations

Suicide ideation and suicide impact a rapidly rising number of individuals each year, however our society has not envisioned a way to increase help-seeking behaviors to decrease these numbers. The literature discusses many barriers and hurdles to help-seeking, but the focus of SI within the context of help-seeking has not been studied in depth. The purpose of this qualitative study was to increase knowledge on the process through which individuals determine how and whom to ask for help when experiencing SI. Two sections of themes were found: things that encourage individuals to seek or continue to seek help, and things …

Getting Back On Track After Challenges: A Qualitative Analysis Of Repair Efforts In Intimate Relationships, Tiffany Reid Lotulelei

Theses and Dissertations

All couples confront conflict in their marriage. Finding ways to navigate couple conflict is a topic that has been explored for several decades among marriage researchers (Rollin & Dowd, 1979). Repair, a strategy to help reconcile a situation or conversation that has gone awry, is important in helping couples overcome conflict. When couples are not able to repair and move forward, resentment arises. Unfortunately, the research on repair and resentment is limited, and the complexity of these variables can make it difficult to conceptualize. The present study utilized a qualitative lens (grounded constructivist theory) to explore relational repair and resentment …

Intrapersonal And Interpersonal Predictors Of Hope In Adolescents, Megan M. B. Wilson

Theses and Dissertations

Hope is a variable that is defined in research as a positive outlook on one's future and a plan to achieve that future. Hope has been found to be positively correlated with self-esteem, optimism, and life satisfaction, and negatively correlated with suicide ideation and suicidality. However, there is a lack of research on predictors of hope in adolescents. Adolescents compose the age group that could arguably use the goal-oriented and positive outlook that hope provides the most. This study identified predictors of hope (i.e., depression, maternal and paternal support) in adolescents so as to know how society can give adolescents …

Variational And Covariational Reasoning Of Students With Disabilities, Lauren Rigby

Theses and Dissertations

Mathematics education reform has led to more conceptually focused instruction in the classroom. Yet, students with disabilities are receiving fewer chances than other students to engage in meaningful mathematics. Furthermore, a research divide between mathematics education and special education in mathematics has led to significant gaps in research on the individual and conceptual understanding of students with disabilities. Through task-based interviews and classroom observations, this study begins the process of closing this research gap through an examination of students' understanding of variational and covariational reasoning. Data suggest that the participants, two students with disabilities, increased their conceptual understanding in a …

How A Racial Minority Status Impacts The Feeling Of Safety In Therapy, Bayleigh Serage

Theses and Dissertations

With the lack of adequate mental health care in racial minority communities (NAMI, 2021), more research is needed for clinicians to understand the racial minority client experience. This study aimed to explore the racial minority client's perception of safety during therapy. The MFT- PRN was utilized in order to assess safety for racial minority clients at the start of therapy and later on as the alliance changes. The study hypothesized that racial minority clients would initially report a lower feeling of safety in therapy and would show lower feelings of safety after four sessions of therapy when compared to demographic …

In-Situ Chlorine Gas Generation For Chlorination And Purification Of Rare Earth And Actinide Metals, Mark H. Schvaneveldt

Theses and Dissertations

Rare earth and actinide metals, critical to security, medicine, and the economy, have been processed through methods such as solvent extraction and electrorefining. To minimize radiological waste and improve yield, a 'chloride volatility' process--also known as the chlorination and volatilization process (CVP)--has been proposed and demonstrated for processing rare earths. The process takes advantage of the low vapor pressure of rare earth chlorides (<700 >°C), CaCl2 was added to LaCl3 to lower the melting temperature. LaCl3 electrochemical behavior has not previously been studied in CaCl2. Cyclic voltammetry (CV) and square wave voltammetry (SWV) were applied to LaCl3 salts in CaCl2-LiCl …

Cytochrome C: A Potential Early Biomarker Of Diabetic Retinopathy, Ileana G. Villarreal

Theses and Dissertations

Diabetic retinopathy is an ocular disease which appears in patients who experience progression of diabetes mellitus over a continuous period. Oftentimes, patients go undiagnosed due to the fact that there is no way to determine when the exact moment a patient develops diabetic retinopathy. Ophthalmologists and other eye specialists diagnose a patient with diabetic retinopathy once the patient begins to show progressed symptoms of the disease. Various experiments have been previously performed to increase our knowledge of the connection of diabetic retinopathy and early biomarkers of the disease. Several studies have determined the effects of diabetic retinopathy and apoptosis with …

Towards Sustainable Cities: Life Cycle Cost Analysis Of The Construction Of A Novel Wastewater Management System, Bibhas B. Tanmoy

Theses and Dissertations

Wastage of water is one of the most common environmental issues in the modern era. However, if this level of usage can be controlled, or recirculated properly, the wastage can be lowered down to a very minimum. In the conventional residential plumbing system, blackwater and greywater gets mixed and goes through the same sewage pipe. This mixture turns the whole wastewater amount into blackwater, which requires complex treatment before discharge. Greywater on the other hand can be discharged to waterbodies requiring almost zero treatment. In this study, a new wastewater management method is proposed where the plumbing system is split …
