A Permutation-Based Confidence Distribution For Rare-Event Meta-Analysis, Travis Andersen

Theses and Dissertations

Confidence distributions (CDs), which provide evidence across all levels of significance, are receiving increasing attention, especially in meta-analysis. Meta-analyses allow independent study results to be combined to produce one overall conclusion and are particularly useful in public health and medicine. For studies with binary outcomes that are rare, many traditional meta-analysis methods often fail (Sutton et al. 2002; Efthimiou 2018; Liu et al. 2018; Liu 2019; Hunter and Schmidt 2000; Kontopantelis et al. 2013). Zabriskie et al. (2021b) develop a permutation-based method to analyze such data when study treatment effects vary beyond what is expected by chance. In this work, …

Localized Heat Therapy Improves Mitochondrial Function In Human Skeletal Muscle, Erik D. Marchant

Theses and Dissertations

Physical activity results in various types of stress in skeletal muscle including energetic, oxidative, and heat stress. Acute exposure to stress impairs skeletal muscle mitochondrial function. In contrast, chronic intermittent exposure to mild stress through exercise training results in increased mitochondrial content and respiratory capacity. While oxidative and energetic stress have received much attention regarding their long-term effect on skeletal muscle mitochondria, heat stress is not well understood. The purpose of this work was to investigate the effects of localized heat therapy on human skeletal muscle mitochondria, and to compare these effects to those of high-intensity interval exercise training. To …

Inhibition Of Cell Adhesion And Actin Localization During Migration Upon Protective Antigen Mutant Ligand Binding To The Capillary Morphogenesis Gene 2, Sai Lun Lee

Theses and Dissertations

Capillary Morphogenesis Gene 2 protein (CMG2) is a type 1 transmembrane receptor known as the anthrax toxin receptor 2 (ANTXR2). While it is documented that the cell surface receptor CMG2 mediates anthrax toxin entry into the cell via endocytosis, the physiological role of CMG2 is not well understood. Others have suggested that CMG2 may have a role in mediating ECM homeostasis and angiogenesis. Additionally, both anthrax protective antigen (PA) and a furin protease-resistant mutant, PASSSR, inhibit corneal neovascularization in a mouse model, and interestingly PASSSR has a greater affinity to CMG2 receptor. PASSSRalso has a more potent antiangiogenic effect than …

Settler-Author Allyship In Centering Indigenous Ecologies: Communal Will Through Collective Environmental Guilt In This Tender Land And Caleb's Crossing, Elena Marie Arana

Theses and Dissertations

The January 2021 edition of PMLA housed an entire cluster on "Indigenous Literatures and the Anthropocene," in which at least four of the eight non-Indigenous contributors directly addressed and supported a call for learning from and collaborating with Indigenous voices. The unanimity of the discussion dissolves somewhat drastically when considering exactly how this should be done, leading Melanie Taylor to voice one of the framing questions of the cluster: "If it is increasingly clear that not all members of Anthropos are equal drivers of the Anthropocene, and that not all are uniformly compromised by its havoc, how can we begin …

The Protective Potential Of Family Relationship Strength As It Relates To Suicidal Thoughts And Behavior In Ace-Exposed Adolescents And Emerging Adults, Collin Wright

Undergraduate Honors Theses

Introduction: Adverse Childhood Experiences (ACEs) are known to cause higher incidences of Suicidal Thoughts and Behaviors (STBs) in young people. Family Relationship Strength (FRS) is a known protective factor against STBs. However, there is little research on the protective nature of FRS once ACEs have been experienced by a young person. The aim of our analysis is to examine whether the strong protective nature of FRS holds true even in ACE- exposed youth.

Methods: A sample of 139 patients at the Brigham Young University Comprehensive Clinic (aged 12-25) was obtained from the BYU Marriage and Family Therapy Practice Research Network. …

Mutants, Sentinels, And Cerebro: Messages About Technology And Society In Science Fiction Films, Paige Marie Lee

Theses and Dissertations

Technology plays a significant role in society and in entertainment. People hold an ambivalent attitude about technology that is often illustrated in science fiction films. Much like myth telling stories to teach a lesson, science fiction films caution viewers of the effects of powerful technology usage in culture today. This thesis examines X-Men to show how relevant principles found in myth continue to be relevant to media consumption. Using media ecology to inform the reader about the technological environment (Mumford, 1944), this analysis of technology portrayed in X-Men shows the implications real world technology, such as radiation, weapons, and artificial …

A simplified Chinese version of the DES was developed and tested using 34 Chinese undergraduate (second year) nursing students. They participated in six simulation scenarios and debriefings. Eight experts were consulted to determine the content validity of the scale. Critical ratio method, Cronbach’s alpha, intraclass correlation coefficient, correlation …

Using Connections To Make Predictions On Dynamic Networks, Rebecca Dorff Jones

Theses and Dissertations

Networks are sets of objects that are connected in some way and appear abundantly in nature, sociology, and technology. For many centuries, network theory focused on static networks, which are networks that do not change. However, since all networks transform over time, static networks have limited applications. By comparison, dynamic networks model how connections between objects change over time. In this work, we will explore how connections in dynamic networks change and how we can leverage these changes to make predictions about future iterations of networks. We will do this by first considering the link prediction problem, using either Katz …

The Caregiver's Conflict: The Toll Of Death And Dying On Nurses' Mental Health And Wellbeing, Madison Brown

Student Works

A major responsibility for nurses is caring for patients during the end-of-life process, as well as helping families and patients cope with the death and dying process. It is well known that death and dying greatly impacts families, but little holistic research has been done on how death and dying impacts nurses’ mental and emotional wellbeing. Using databases Google Scholar, Web of Science, and EBSCO, 14 articles were analyzed regarding the impact of death on nurses’ mental health. Results show that the age of a patient plays a bigger role on death impact than nursing specialty does, as younger patients’ …

Level systems provide systematic support for teachers and students who need additional behavior support. The purpose of this study was to evaluate the perspectives of faculty members from a self-contained school, for special education students with severe behavior needs, which has sustained the use of a school-wide, behavior management level system for nearly 30 years. A total of 11 faculty members were interviewed using the critical incident technique, a qualitative methodology used as an exploratory tool in early stages of research. Interviews detailed the observable behaviors and specific events, critical incidents, that helped or hindered the sustainability of their school's …

Effects Of Autonomy, Competence, And Relatedness On Employee Outcomes: A Literature Review, Joseph Wilson

Student Works

Most business organizations understand that employees are an essential part of their success and as such, much research has gone into understanding the most effective ways of eliciting favorable employee outcomes. The self-determination theory (SDT) is one result of the extensive research that has been done on the topic. SDT suggests a relationship between positive employee outcomes and the satisfaction of employees’ three basic psychological needs (TBPN): autonomy, competence, and relatedness. This literature review was undertaken to examine empirical studies that have researched the ways psychological needs are satisfied, and the effects of the TBPN on employee outcomes in the …

Comparative Sequence Analysis Elucidates The Evolutionary Patterns Of Yersinia Pestis In New Mexico Over Thirty-Two Years, M. Elizabeth Warren

Theses and Dissertations

Yersinia pestis, a gram-negative bacterium, is the causative agent of plague. Y. pestis is a zoonotic pathogen that occasionally infects humans, and is endemic in the western United States. History gives evidence of three main plague pandemics. The first, originating in Egypt in 541AD, is known as the Justinian plague. The second, perhaps most well-known, is thought to have emerged in 1347AD in China, and is called the Black Death. The third, and current plague pandemic, also emerged in China in 1855. In 1899, Y. pestis was established in California, and the plague in other parts of America evolved from …

The continual increase of wireless technologies in the world has motivated the use of phased arrays to mitigate radio frequency interference (RFI). There are many methods of performing beamforming for RFI rejection, but they are traditionally physically large and complicated solutions. Phased arrays need to be shrunk and made cheaper for them to see widespread use. This work presents several compact phased array receivers for different applications. The first part of this thesis presents a software GPS processor for a digital beamforming GPS receiver. The receiver is small enough to be flown on drones and enables GPS signals to be …

The Influence Of Thc, Opioids, And Age On The Plasticity Of Excitatory Inputs To Ventral Tegmental Area Gaba Neurons, Isaac Brent Ostlund

Theses and Dissertations

Adults exhibit significant differences in drug vulnerability, learning ability, and emotive processing than adolescents. Long-lasting synaptic changes, including long-term depression (LTD), can endure many hours and are believed to be key to encoding memories and persistent cognitive changes such as addiction. The ventral tegmental area (VTA) is the primary source of midbrain dopamine (DA) and is regulated by local inhibitory GABA neurons. GABA regulation can decrease, resulting in dis-inhibition of DA neurons and increased feelings of reward, learning, or salience attachment to memories. Endocannabinoids (eCBs) are signaling molecules that often result in synaptic plasticity changes, and the eCB system has …

Thalamic Shape Abnormalities Differentially Relate To Cognitive Performance In Early-Onset And Adult-Onset Schizophrenia, Derin J. Cobia, Chaz Rich, Matthew J. Smith, Pedro Engel Gonzalez, Will Cronenwett, John G. Csernansky, Lei Wang

Faculty Publications

Early-onset schizophrenia (EOS) shares many biological and clinical features with adult-onset schizophrenia (AOS), but may represent a unique subgroup with greater susceptibility for disease onset and worsened symptomatology and progression, which could potentially derive from exaggerated neurodevelopmental abnormalities. Neurobiological explanations of schizophrenia have emphasized the involvement of deep-brain structures, particularly alterations of the thalamus, which have been linked to core features of the disorder. The aim of this study was to compare thalamic shape abnormalities between EOS and AOS subjects and determine whether unique behavioral profiles related to these differences. It was hypothesized abnormal thalamic shape would be observed in …

Effects Of Optical Configuration And Sampling Efficiency On The Response Of Low-Cost Optical Particle Counters, Brady Scott Hales

Theses and Dissertations

Hazards associated with air pollution motivate the search for technologies capable of monitoring individual exposure to gaseous pollutants and particulate matter (PM). A Low-cost Optical Particle Counter (OPC), costing less than 50 USD, is an example of such technologies. Currently, OPCs are widely used to measure the concentration of particle matter in ambient air. While these low-cost air quality sensors are widely available, the accuracy and precision of these devices is highly uncertain. Consequently, the purpose of this thesis is to present an analytical model of two generic, low-cost OPCs based on the Laws of Conservation of Mass, Momentum, and …

Background: Traumatic brain injury is a significant public health problem. Heart rate variability is a potential modality to measure physiological dysfunction following traumatic brain injury to assist in determining recovery time and the relationship between traumatic brain injury severity and recovery. To date, a summary of the evidence across injury severities and the possible role of heart rate variability biofeedback in traumatic brain injury treatment is lacking but needed to determine potential clinical utility. Participants and Methods: We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines. Systematic literature searches on CINAHL, Embase, PsycINFO, SPORTDiscus, and MEDLINE …

Physical Aspects Of Sexuality, Attachment, And Sexual Satisfaction, Chelsea Zollinger Allen

Theses and Dissertations

Healthy sexuality includes relational, emotional, and physical elements (Busby et al., 2021). However, there are gaps in what is known about the physical aspects of sexual relationships. Genital acceptance and physical sexual knowledge are two areas of physical relationships that may have an effect on the satisfaction of sexual relationships. Attachment, namely levels of anxious and avoidant attachment, is another factor that has been related to sexual relationships (Allsop et al., 2021; Bennett et al., 2019; Busby et al., 2020). Results from a dyadic sample of 515 couples who had been in a relationship for at least two years were …

Methods: A VEM, including information about vaccine-preventable diseases, benefits of vaccines, principles of community or herd immunity, and where to go to get vaccinated, was created for freshman students. Student vaccine concerns were identified using a pretest/posttest quasi-experimental design using an online questionnaire before and after completing the VEM. After the VEM, participants were also asked to identify …

Cherry Red Greenwashing: The Rhetoric Behind Corporate Recycling Narratives, Jessica Wallace Haws

Theses and Dissertations

As the public becomes more aware of environmental issues, corporations are pressed to consider and address the sustainability of their practices. Unwilling to drastically change business models, many corporations turn to greenwashing in an attempt to construct an environmentally friendly image while doing little to nothing to address sustainability issues. Using Kenneth Burke's work on identification and terministic screens, I analyze The Coca-Cola Company's "2020 World Without Waste Report" to illuminate how consumers come to believe in and identify with corporate greenwashing tactics. In line with Burke's theories related to identification, I argue that Coca-Cola's greenwashing strategies can be categorized …

Autism spectrum disorder (ASD) is a largely prevalent disorder that is typically first diagnosed at a young age. This diagnosis can have extreme effects on the family members of these children with the parents or guardians receiving the greatest impact of these effects. Having a child with ASD can be detrimental to a parent’s mental health as well as to the family’s functioning capabilities. This literature review found and reviewed 11 articles to interpret the psychological effects that having a child with ASD has on parents. Additionally, this article aimed to determine the effectiveness of intervention programs that have been …

Atg9a And Atg13 Cooperate To Drive Basal Autophagy, Daniel Morgan Poole

Theses and Dissertations

Autophagy, as the name suggests, is a cellular process of self-eating in which cytoplasmic debris is engulfed by a double membrane vesicle dubbed the autophagosome and is ultimately degraded and recycled by proteases in the lysosome. The process is initiated by a group of core ATG proteins, including a multi-pass transmembrane protein called ATG9A. Although ATG9A has been shown to be essential for both stress induced and basal autophagy, its mechanism and interaction network remain largely illusive. Our current study employs BioID proteomics to identify a network of interactors, including regulators of membrane fusion and vesicle trafficking, such as TRAPP, …

"Do Not Blame Me": James Baldwin On White Christian Guilt And Racial Repentance, Celeste Lafollette

Theses and Dissertations

James Baldwin, a Black American writer, contends that the root cause of America’s racial problem is not necessarily prejudice or hatred but guilt. In his essay, “White Man’s Guilt,” Baldwin says that most of the arguments white people use today against the reality of America’s racial problem can be reduced to a plea: “Do not blame me. I was not there. I did not do it” (Price 411). In many of his essays, Baldwin explores white America’s long history of guilt, denial, and justification, and he explains that many white Christians—in an attempt to avoid blame and protect their power, …

Psychological Distress Of Spousal Caregivers Of Older Adults: The Moderating Role Of Marital Quality, Avalon White

Theses and Dissertations

Caregiving, specifically caregiver burden, is commonly related to decreased psychological well-being. Conversely, marital quality is positively related to psychological well-being, though existing literature presents mixed findings as to whether or not a gender difference exists in this relationship. The current study examined the relationship between objective and subjective spousal caregiver burden and psychological distress with marital quality as a moderator. Gender differences in this relationship were also explored. 1,066 spousal caregivers from the National Study of Caregiving (NSOC) were used to estimate cross-sectional moderation models and plot significant interactions in Mplus. Results indicated a significant positive relationship between subjective caregiver …

Implementation Of An Automated Grading Tool For Phonetic Transcription Training, Marisha Speights Atkins, Dallin J. Bailey, Cheryl D. Seals

Faculty Publications

Clinical phonetic transcription is regarded as a highly specialised skill requiring hours of practice for mastery. Although this skill is a critical part of students’ clinical preparation to become speech-language pathologists, students often report feeling unprepared to apply the skill in clinical practice. Previous studies suggest that increased opportunities for practice and timely feedback on transcriptions are needed in order to develop skill confidence. However, providing more opportunities for practice can be impeded by the limited resources to manage the grading of additional assignments. The purpose of this study is to show the implementation of a web-based learning management system …
