Minding Accidents, Teneille R. Brown

Utah Law Faculty Scholarship

Tort doctrine states that breach is all about conduct. Unlike in the criminal law, where jurors must engage in an amateur form of mindreading to evaluate mens rea, jurors are told that they can assess civil negligence by looking only at how the defendant behaved. But this is false. Foreseeability is at the heart of negligence—appearing as the primary tests for duty, breach, and proximate cause. And yet, we cannot ask whether a defendant should have foreseen a risk without interrogating what he subjectively knew, remembered, perceived, or realized at the time. In fact, the focus on actions in negligence …

The Relationship Between Sex Role, Mindfulness, Perceived Stress, Anxiety, And Flow In Team Sport Female Athletes, Vanessa Chafos

Seton Hall University Dissertations and Theses (ETDs)

In recent years, studies have emerged that support the use of mindfulness interventions to enhance sport performance (Cathcart et al, 2014; Gardner & Moore, 2012; Jekauc et al., 2017; Kee & Wang, 2008; Moen et al., 2015). Among these studies, there is a gap in the literature in regards to sex role and mindfulness, perception of stress, and ability to reach a flow state. This study discusses current sport psychology literature and explores the relationship between sex role, mindfulness, perceived stress, anxiety, and flow among 185 team sport female athletes. Correlational Analyses from this study indicated that there is a …

Endothelial Metabolism In Pulmonary Vascular Homeostasis And Acute Respiratory Distress Syndrome, Reece P. Stevens, Sunita S. Paudel, Santina C. Johnson, Troy Stevens, Ji Young Lee

University Faculty and Staff Publications

Capillary endothelial cells possess a specialized metabolism necessary to adapt to the unique alveolar-capillary environment. Here, we highlight how endothelial metabolism preserves the integrity of the pulmonary circulation by controlling vascular permeability, defending against oxidative stress, facilitating rapid migration and angiogenesis in response to injury, and regulating the epigenetic landscape of endothelial cells. Recent reports on single-cell RNA-sequencing reveal subpopulations of pulmonary capillary endothelial cells with distinctive reparative capacities, which potentially offer new insight into their metabolic signature. Lastly, we discuss broad implications of pulmonary vascular metabolism on acute respiratory distress syndrome, touching on emerging findings of endotheliitis in coronavirus …

Role Identity And Engagement Behaviors Of Student-Athlete Alumnae, Matthew Charles Brinton

Dissertations

The purpose of this qualitative phenomenological research study was to explore the meanings volleyball student-athlete alumnae (SAA) from a doctoral granting research institution in the Rocky Mountain region (Rocky Mountain Regional University or RMRU) associate with their lived experiences and how those interpretations shape their engagement behaviors as alumnae. Using Stryker’s (1980) interpretation of Symbolic Interactionism as a theoretical framework, I interviewed seven participants and found that the meaning they associated with their experiences varied by their placement in different types of closed positions, those that require permission, invitation, or special status for membership. My findings suggest that there is …

The Impact Of Perceived Parenting Styles During Childhood Experiences Of Bullying On Emerging Adult Attachment, Callie Kathryn King

Dissertations

Given the prevalence of bullying during youth and the substantial negative outcomes of these experiences during adulthood, this study evaluated youth bullying experiences, perceived parenting style, and emerging adult attachment styles. The purpose was to determine the extent to which perceived parenting style moderates the relationship between youth bullying experience and emerging adult attachment to primary caregivers, romantic partners, and best friends above and beyond what youth bullying experience already predicts. The interaction between youth bullying experience and perceived parenting style were hypothesized to account for a significant amount of the variance in the outcome of emerging adult attachment style. …

Conserved Non-Pocket Interactions Drive The Diversity Of Peptide Presentation By Mhc Class I Molecules, Kyle Jackson

Dissertations and Theses (Open Access)

Cytotoxic T-lymphocytes (CTL) can lyse infected or transformed cells through recognition of peptides presented on human leukocyte antigen (HLA) molecules. A thorough understanding of peptide-HLA interactions is needed for improvement of CTL-based immunotherapies. We observed that aspartic acid (D) and glutamic acid (E) at peptide position 4 are highly prevalent in HLA-I peptide ligands, and discovered that they interact with arginine (R) in position 65 and lysine (L) in position 66 of the α1 helix of the binding groove in HLA-A*0201 and HLA-A*2402. Since this interaction differed from well-characterized peptide-HLA anchor interactions mediated by peptide position 2 and the C-terminus, …

Elucidating The Modulatory Role Of Dopamine In The C. Elegans Chemosensory Ash Neuron, Cory Kunkel

Electronic Theses, Projects, and Dissertations

The neurotransmitter dopamine regulates chemosensory avoidance behavior in the model organism Caenorhabditis elegans. Avoidance behaviors are mediated by the polymodal ASH nociceptive sensory neurons, and behavioral avoidance of stimuli detected by ASH is less robust when dopamine signaling is impaired. We are investigating the neural response of the ASH neurons to various stimuli; our investigation includes the behavioral and physiological responses from the ASH neurons as dopamine signaling is manipulated to better understand the effects of dopamine on these sensory neurons. We hypothesize that dopamine plays a regulatory role on the ASH neurons, lessening the response of the ASH …

Serotonin 1b/1a Receptor Modulation On Behavioral Flexibility In C57bl/6j Mice, Brandon L. Oliver

Electronic Theses, Projects, and Dissertations

Pharmacological activation of the 5-HT1B and 1A receptors has been implicated in OCD-like behaviors in rodents such as increased perseverative circling, checking behaviors, and locomotor stereotypy. However, little is understood about the effects of 5-HT1B and 1A receptor activation on behavioral inflexibility, a common symptom associated with OCD. The present study utilized the 5-HT1B/1A receptor agonist RU24969 at 0.01, 0.1, and 1.0 mg/kg to test three hypotheses. The first hypothesis predicted RU24969 would lead to a dose-dependent impairment on behavioral flexibility in C57BL/6J mice. It was also predicted that male C57BL/6J mice would be more inflexible than female C57BL/6J mice …

Reconstructing 1856-7 California Mining Patterns From Placer Gold Recovered From The Wreck Of The Ss Central America, Kathryn Ruth Vonsydow

Electronic Theses, Projects, and Dissertations

The discovery of the SS Central America 1857 shipwreck site provides a time capsule that can be used to address questions about the spatial and temporal patterns of placer mining in California during the peak of the gold rush. Samples of placer gold in the collections of museums and private individuals can have uncertain pedigree due to labeling issues and alterations by cleaning and curatorial processes. However, placer gold from the 1857 shipwreck could only have come from the Mother Lode Country of California, as no other gold districts had yet been found in western North America. I compared the …

The analysis of the interviews identified the leadership styles of democratic, situational and participative as being the most common among …

Spatial Analyses Of Gray Fossil Site Vertebrate Remains: Implications For Depositional Setting And Site Formation Processes, David Carney

Electronic Theses and Dissertations

This project uses exploratory 3D geospatial analyses to assess the taphonomy of the Gray Fossil Site (GFS). During the Pliocene, the GFS was a forested, inundated sinkhole that accumulated biological materials between 4.9-4.5 mya. This deposit contains fossils exhibiting different preservation modes: from low energy lacustrine settings to high energy colluvial deposits. All macro-paleontological materials have been mapped in situ using survey-grade instrumentation. Vertebrate skeletal material from the site is well-preserved, but the degree of skeletal articulation varies spatially within the deposit. This analysis uses geographic information systems (GIS) to analyze the distribution of mapped specimens at different spatial scales. …

Adverse Childhood Experiences (Aces): Assessing Their Impact On Mental Health Outcomes Among Us Children And The Mitigating Role Of Resilience, Glory Okwori

Electronic Theses and Dissertations

ACEs are traumatic life events occurring during childhood that can have negative effects. Common mental disorders that are diagnosed in childhood are attention-deficit/hyperactivity disorder (ADHD), behavior disorders, anxiety and depression. The associations between ACEs and such problems in children have not been significantly examined. There are protective factors that can help reduce the effects of exposure to ACEs that have not been fully explored.

The purpose of this research study was to examine: 1) the prevalence of mental health outcomes in children; 2) the associations between ACEs, resilience and mental health outcomes; and 3) the role of resiliency as a …

Examining Predictors Of Attitudes And Knowledge Of Registered Nurses And Nursing Students In Tennessee Toward Pregnant And Perinatal Women With A Substance Use Disorder, Jessica Patrylo

Electronic Theses and Dissertations

Substance use disorders (SUDs) among pregnant and perinatal women continue to be a national public health crisis. Furthermore, nursing students and perinatal nurses have historically negative and punitive attitudes toward this vulnerable population of women. As nurses are primary care providers for pregnant and perinatal women, this is troublesome as perinatal patients express feeling stigmatized by nurses whom they should be able to trust. This contributes to the reluctance of women to seek needed medical and prenatal care. Tennessee was the first state to criminalize drug use in pregnancy and has higher neonatal abstinence syndrome (NAS) rates, which were more …

The Impact Of Natural Playscapes On Toddler Play, Laura J. Pearce

Electronic Theses and Dissertations

A distinct lack of data related to the impact of natural environments on children birth to age 3 was identified by a thematic review of the existing literature. With this in mind, the researcher designed a limited scope quantitative study to explore the potential for extending the existing body of research to include this younger age. The study used a time sampling method to code behaviors that occurred in videos collected of children from 12 to 35 month who were playing on the playground at their childcare facility. The playscapes were classified as naturalistic or manufactured. The data was then …

Nitrogen-Doped Carbon Fiber Ultramicroelectrodes As Electrochemical Sensors For Detection Of Hydrogen Peroxide, Eric Wornyo

Electronic Theses and Dissertations

Carbon fiber ultramicroelectrodes (CF-UMEs) are commonly used as electrochemical probes and sensors due to their small size, fast response, and high signal-to-noise ratio. Surface modification strategies are often employed on CF-UMEs to improve their selectivity and sensitivity for desired applications. However, many modification methods are cumbersome and require expensive equipment. In this study, a simple approach known as soft nitriding is used to prepare nitrogen-doped CF-UMEs (N-CF-UMEs). Nitrogen groups introduced via soft nitriding act as electrocatalytic sites for the breakage of O-O bonds during the reduction of peroxides like H₂O₂, a common target of biosensing strategies. …

Bilateral Ground Reaction Force Jumping Asymmetry And Performance, Keith Painter

Electronic Theses and Dissertations

The prevalence of asymmetry in performance research has increased in recent years with mixed results. Much of the performance research has focused on unilateral jumping activities attempting to show relationships to other performance variables. However, bilateral ground reaction forces (bGRF) from jumps are more frequently assessed in athlete monitoring programs and the asymmetry from those jumps could be a simple addition to data already being collected. Research into bGRF asymmetries is lacking and no studies have addressed longitudinal changes. Additionally, research into the relationship of asymmetries to performance have infrequently used athletes. For these reasons, this dissertation will focus on …

Self-Reported Health Among Sexual Minorities In The United States, Christopher Burton

Electronic Theses and Dissertations

Previous literature on LGBTQ+ people (lesbian, gay, bisexual, transgender, queer/questioning, and other sexual minorities) reports that this community experiences greater health problems than heterosexuals. LGBTQ+ people experience higher rates of chronic conditions, STIs, addiction, poor mental health, and cancer, which highlights the importance of capturing data regarding health. A growing concern is that social surveys fail to find meaningful ways to gather gender and sexuality data to understand possible health disparities for LGBTQ+ people. This study uses data from the General Social Survey to examine the physical and mental health outcomes of LGB people compared to straight people in a …

Isotopic Analysis And Mobility Mapping Of Mammuthus Columbi From The Mammoth Site In South Dakota, Matthew Harrington

Electronic Theses and Dissertations

The Mammoth Site in Hot Springs, South Dakota preserves a unique death assemblage of sub-adult and adult male Columbian mammoths (Mammuthus columbi). Extensive work on the site has led to a detailed understanding of the taphonomy of the assemblage; yet the life histories and ecology of these mammoths remain relatively unknown. Tooth enamel from four Mammoth Site mammoth individuals were bulk sampled with one of the individuals (MSL 742) also serially micro-sampled for 𝛿¹³C, 𝛿¹⁸O, and ⁸⁷Sr/⁸⁶Sr. Isotopic results indicate that MSL 742 remained within the southern and western Black Hills …

Evidence-Based Program Selection And Duration Of Implementation Of Social-Emotional Learning As Related To Student Growth And Non-Academic Outcomes, Colleen K. Weems

Electronic Theses and Dissertations

This quantitative, nonexperimental study addressed the gap between research-established benefits and outcomes of social-emotional learning implementation as compared to actual instances of implementation. It has been suggested that social-emotional learning as a systemic initiative is necessary for school health (Elias et al., 2013). Additionally, most educators relay some confidence in the importance of social-emotional learning; however, around half report actual implementation within their school (Atwell & Bridgeland, 2019).

Focusing on social-emotional learning as a whole as well as the specificity of use of CASEL SELect programs, the research questions of this study explored differences between implementation and usage, length of …

Educator Perceptions Of Generational Poverty, Adverse Childhood Experiences And Student Learning, Rachel Cook

Electronic Theses and Dissertations

The purpose of this qualitative study was to examine educators perceptions of the effects of generational poverty and adverse childhood experiences on student learning and to understand the factors that might facilitate breaking the cycle of generational poverty and adverse childhood experiences with respect to student learning.

Data collection strategies included individual interviews and document review. Analysis of data occurred in three phases: categorization of data, building the explanation in narrative form and reexamination of the data. The analysis of the data was based on Payne’s idea of generational poverty and the CDC-Kaiser Permanente Adverse Childhood Experiences(ACE) study.

The credibility …

Forgiveness, Gratitude, Humility, And Spiritual Struggle: Associations With Religious Belief Status And Suicide Risk, Benjamin B. Hall

Electronic Theses and Dissertations

Religion is a known contributor to suicide risk, with both positive and negative effects. Negative religious experiences, such as spiritual struggle, can exacerbate suicide risk. Alternatively, religion may promote positive psychological characteristics associated with reduced suicide risk, such as forgiveness, gratitude, and humility. However, research has yet to assess how religious changes, including conversion and deconversion, affect the linkage between religious risk and protective factors and suicidal behavior. We conducted three studies assessing these associations across four belief status groups: life-long religious believers, former religious non-believers who now believe, life-long religious non-believers, and former religious believers who no longer believe. …

Neuroinflammation, Peripheral Inflammation And Gut Microbiome Profiles In Male Mice From Two Proposed Mouse Models Of Social Behavior Deficits, Sarah Parkinson

Electronic Theses and Dissertations

Autism spectrum disorder (ASD) is a neurodevelopmental disorder marked by social deficits and repetitive actions. A communication pathway exists between the brain and gut called the gut-brain axis. It is thought that gut bacteria can secrete signaling molecules, triggering inflammation across the body. These studies attempt to determine if markers are expressed in two mouse models of ASD behaviors, BTBR and a valproic acid model. Immunohistochemistry of ionized calcium binding adaptor molecule 1 from male mouse brain tissue showed no microglial activation in any group. Cytokine analysis did exhibit an increase in interleukin 1 (IL-1) in male adult mice only. …

Sterol Biosynthesis In Four Green Algae: A Bioinformatic Analysis Of The Ergosterol Versus Phytosterol Decision Point, Adam Voshall, Nakeirah T.M. Christie, Suzanne L. Rose, Maya Khasin, James L. Van Etten, Jennifer E. Markham, Wayne Riekhof, Kenneth Nickerson

Kenneth Nickerson Papers

Animals and fungi produce cholesterol and ergosterol, respectively, while plants produce the phytosterols stigmasterol, campesterol, and β-sitosterol in various combinations. The recent sequencing of many algal genomes allows the detailed reconstruction of the sterol metabolic pathways. Here, we characterized sterol synthesis in two sequenced Chlorella spp., the free-living C. sorokiniana, and symbiotic C. variabilis NC64A. Chlamydomonas reinhardtii was included as an internal control and Coccomyxa subellipsoidea as a plant-like outlier. We found that ergosterol was the major sterol produced by Chlorella spp. and C. reinhardtii, while C. subellipsoidea produced the three phytosterols found in plants. In silico analysis of the …

Garrett, Jacques Izard, Yin Cao, Mingyang Song, Curtis Huttenhower, Shuji Ogino, Andrew T. Chan

Department of Food Science and Technology: Faculty Publications

Introduction: We recently described the sulfur microbial diet, a pattern of intake associated with increased gut sulfur-metabolizing bacteria and incidence of distal colorectal cancer (CRC). We assessed whether this risk differed by CRC molecular subtypes or presence of intratumoral microbes involved in CRC pathogenesis (Fusobacterium nucleatum and Bifidobacterium spp.).

Methods: We performed Cox proportional hazards modeling to examine the association between the sulfur microbial diet and incidence of overall and distal CRC by molecular and microbial subtype in the Health Professionals Follow-Up Study (1986-2012).

Results: We documented 1,264 incident CRC cases among 48,246 men, approximately 40% …

Against Sex Education Pedagogy, Sex Work, And State Violence, Caitlin Howlett

Education Studies Faculty publications

Why do we have sex education? For whom does it exist, and who is it against? This book explores these questions, ultimately calling into question the very existence of sex education itself. The analysis is centred on the marginalised lives of sex workers. This focus allows us to see sex education and sex work in a new light and provides insights into the implications of sex education in public schools and teacher education. By considering the relationship between sex education and sex work, Caitlin Howlett reveals the way in which sex education exists as a form of state violence, and …

Investigation Into The Evolution Of Heterogeneity Within Secondary Replicons And Their Maintenance In Genus Variovorax, Christopher Ne Ville

Electronic Theses, Projects, and Dissertations

Approximately 10% of all bacterial genomes sequenced thus far contain a secondary replicon. This considerable genetic reservoir contains many potentially mobilizable elements, allowing for the formation of many unique secondary replicons. This property of bacterial populations vastly increases the genomic diversity available to species that effectively take up and maintain these replicons. Members of the genus Variovorax have extensive heterogeneity in genome architecture, including sequenced isolates containing plasmids, megaplasmids, and chromids. Using available Illumina data on the NCBI database, we have completed these assemblies using 3^rd generation sequencing methods on 17 members of this genus. We have sequenced, assembled, …

Feminist Readings Of Evangelicalism: Views On Gender And Sexuality From Evangelical Perspectives, Rubi Elizabeth Cibrian Llamas

Electronic Theses, Projects, and Dissertations

There are approximately over 10,000 distinct religious practices in the world, some of these religions are either a variation of each other or very different. Historically and presently, certain religions are positioned in popular discourse as not fit for our times or too conservative for example, evangelicalism and Islam have often been two religions that are viewed as ‘too traditional’ and in need of modernization of their ‘extreme’ beliefs.

This typically gets reduced to specific ideologies and viewpoints revolving around feminism and LGBTQIA+ identity. Ideologies regarding the treatment and place of women have been backed up by ‘evidence’ presented in …
