Meaning Making And Athletic Gender Discrimination: Associations Between Sports Participation And Gender Discrimination Among Adolescent Females, Chenae Christensen Duerden Jun 2023

Meaning Making And Athletic Gender Discrimination: Associations Between Sports Participation And Gender Discrimination Among Adolescent Females, Chenae Christensen Duerden

Theses and Dissertations

Research suggests that participation in athletics provides adolescent females with a variety of positive mental and physical benefits. While Title IX paved the way for increased female participation in organized sports, female athletes, including adolescents, continue to face various forms of gender discrimination. Research also suggests that females with a strong feminist identity are more likely to identify and speak out against gender discrimination. Accordingly, this study seeks to examine the association between gender discrimination and sports participation and the potential moderating role of feminist identity and cognitive appraisals of discrimination on this relationship. Participants were 580 adolescent females (age …

First Documentation Of Ergasilus Centrarchidarum On Smallmouth Bass In Idaho, Danielle Perkins, John W. Heckel Iv, Brett High, Eric J. Billman Jun 2023

First Documentation Of Ergasilus Centrarchidarum On Smallmouth Bass In Idaho, Danielle Perkins, John W. Heckel Iv, Brett High, Eric J. Billman

Western North American Naturalist

Ergasilus centrarchidarum is a parasitic copepod that infects the gills of fishes in the family Centrarchi­dae. This parasite has been introduced in many regions of North America through introduction of infected Smallmouth Bass (Micropterus dolomieu); however, effects of E. centrarchidarum on its hosts have been poorly studied. Ergasilus centrarchidarum was first discovered infecting Smallmouth Bass in Ririe Reservoir in 2020, although timing of introduction remains uncertain. Our objective was to determine prevalence and intensity of infection of E. centrarchidarum on Smallmouth Bass in Ririe Reservoir. We used angling to collect Smallmouth Bass in the upstream portion of Ririe …

Citizen Science In Action: An Updated Distribution For Lampropeltis Pyromelana, Dallin B. Kohler, Bryan T. Hamilton, Drew E. Dittmer, Alison S. Whiting

Western North American Naturalist

The Arizona mountain kingsnake, Lampropeltis pyromelana, is a species of tricolor kingsnake distributed in disjunct patches of montane habitat in the western United States. Historical range maps were based on a small number of specimens, and the growing body of locality data on this secretive species has enabled a significant update to its known distribution. Multiple sources of citizen science data were used to supplement traditional data sources to more accurately delineate the range of this understudied species. We used citizen science data, primarily from iNaturalist and state-initiated surveys in Nevada and Utah, to show that the contemporary distribution …

Integration Of Insoluble And Soluble Dopants Into Steel Using Laser Powder Bed Fusion, Mckay Goodman Sperry Jun 2023

Integration Of Insoluble And Soluble Dopants Into Steel Using Laser Powder Bed Fusion, Mckay Goodman Sperry

Theses and Dissertations

Laser Powder Bed Fusion (LPBF) is an Additive Manufacturing (AM) method whereby complex parts can be built to near net geometry in an automated environment. Parts formed by LPBF have excellent properties and require little post-processing. While LPBF allows for creative designs to reduce weight and part count by integrating sub-components of assemblies, designers are limited to one material within any LPBF print. Although various materials can be used in LPBF, metals are of special interest to many industrial customers due to their high strength and toughness. The metals commonly used for LPBF include iron, aluminum, and titanium alloys. These …

Characterizing Dust From National Wind Erosion Research Network Sites Using Strontium Isotopes, Major And Trace Element Chemistry, And Mineralogy, Abby L. Mangum

Theses and Dissertations

The frequency of dust storms is increasing globally yet it is often difficult to determine dust sources in mixed events. Dust events may negatively impact human health, but the composition of major dust sources is not well characterized in arid regions globally. In the western US, the National Wind Erosion Research Network (NWERN) has various sites evaluating seasonal dust emissions to quantify dust fluxes. We used existing dust samples to characterize the isotopic, chemical, and mineralogical composition of dust over multiple seasons from ten representative NWERN sites and compared with land use, vegetation, and surficial geology. Our results show variability …

Evaluating The Impact Of Math Self-Efficacy, Math Self-Concept, And Gender On Stem Enrollment And Retention In Postsecondary Education, Marcia Bingham Jun 2023

Evaluating The Impact Of Math Self-Efficacy, Math Self-Concept, And Gender On Stem Enrollment And Retention In Postsecondary Education, Marcia Bingham

Theses and Dissertations

Low enrollment and high attrition of women in science, technology, engineering, and mathematics (STEM) continues to be an issue for postsecondary institutions. Improvements in representation of women has been seen in some of the agricultural and biological sciences; however, in many of the more math intensive areas such as geosciences, engineering, mathematics/computer science, and physical sciences (GEMP), women continue to be underrepresented leading to underrepresentation in the workforce and further exacerbating gender gaps. Studies suggest the lack of representation is not due to a gap in math ability between men and women, yet underrepresentation remains predominantly within math intensive STEM …

First Shasta Ground Sloth (Nothrotheriops; Xenarthra) From The Eastern Great Basin, Nevada, Jim I. Mead, Sandra L. Swift, H. Gregory Mcdonald, Steven D. Emslie Jun 2023

First Shasta Ground Sloth (Nothrotheriops; Xenarthra) From The Eastern Great Basin, Nevada, Jim I. Mead, Sandra L. Swift, H. Gregory Mcdonald, Steven D. Emslie

Western North American Naturalist

We present the first record of the Shasta ground sloth (Nothrotheriops shastensis) for the eastern Great Basin. The single right upper second molariform was recovered from the back dirt pile of archaeological test pits excavated during the 1960s and 1970s in Smith Creek Cave, northern Snake Range, White Pine County, Nevada. The precise age of the specimen is indeterminate, although all sediment layers in the area produced radiocarbon dates older than 11,000 cal BP; thus, the specimen is considered of the Rancholabrean Land Mammal Age. All previous accounts of this sloth in the Great Basin are from its …

Plains To Peaks: An Analysis Of The Relationship Between Colorado Butterfly Communities And Altitude, Anna O. James, Kathryn Hokamp, Chris García-Hellmuth, Richard P. Reading Jun 2023

Plains To Peaks: An Analysis Of The Relationship Between Colorado Butterfly Communities And Altitude, Anna O. James, Kathryn Hokamp, Chris García-Hellmuth, Richard P. Reading

Western North American Naturalist

We compared butterfly communities of the Plains, Foothills, and Montane Zones of the Colorado Front Range and examined 3 groups of butterflies—blues (Polyommatinae species), fritillaries (Speyeria and Boloria spp.), and painted ladies (species Vanessa cardui)—for altitude shifts between 2014 and 2020. We conducted these analyses using data collected by volunteer butterfly monitors from the Colorado Butterfly Monitoring Network, a group organized and run by Butterfly Pavilion in Westminster, Colorado. Monitors walked designated routes and counted all butterflies they saw, identifying each to the lowest possible taxonomic group they could. We sorted routes into the 3 altitude zones, organized …

Ecology And Retribution: Blake, Tokarczuk, And Animal Rights, Kristina Isaak Powell Jun 2023

Ecology And Retribution: Blake, Tokarczuk, And Animal Rights, Kristina Isaak Powell

Theses and Dissertations

This thesis explores how Nobel laureate Olga Tokarczuk's 2008 novel, Drive Your Plow Over the Bones of the Dead, engages with William Blake's life and his writings on animal welfare and speaks to current conversations about multispecies justice in the environmental humanities. It argues, first, that in recognizing how this novel's protagonist, Janina, selectively reads Blake to rationalize retributive justice, readers should resist a tendency to mistake this character for Tokarczuk's ideal advocate for environmental ethics. Secondly, it asserts that legal scholars' division between retributive and restorative justice offers valuable framework for approaching both this novel and ongoing debates about …

Marital Stability In Newlywed Remarried Couple Relationships: Positive Communication And Marital Interactions In Shared Moments Or Activities, Colette Hickman-Evans Jun 2023

Marital Stability In Newlywed Remarried Couple Relationships: Positive Communication And Marital Interactions In Shared Moments Or Activities, Colette Hickman-Evans

Theses and Dissertations

Remarriages are more structurally diverse, last less time, are more vulnerable, and at greater risk for divorce than first marriages. The newlywed stage of marriage is a critical time when relationship patterns are established or reinforced that can impact a relationship for years to come, yet very few studies have examined remarried relationships in the newlywed stage. This study examined the association between marital interaction, positive communication, and marital instability in 348 newlywed remarried couple participants from a nationally representative sample. Using structural equation modeling (SEM) and actor-partner interdependence model with mediation (APIMeM), the findings indicated that positive communication was …

Design, Synthesis And Immunological Testing Of Minimal Oligosaccharide Epitopes For Glycoconjugate Vaccines Targeting Capsular Polysaccharides Of Serotypes 3, 4, 7f And 9v Of Streptococcus Pneumoniae, Seth A. Taylor Jun 2023

Design, Synthesis And Immunological Testing Of Minimal Oligosaccharide Epitopes For Glycoconjugate Vaccines Targeting Capsular Polysaccharides Of Serotypes 3, 4, 7f And 9v Of Streptococcus Pneumoniae, Seth A. Taylor

Theses and Dissertations

The rise in antibiotic resistant strains of bacteria has led to the need for new methods of combatting bacterial infection. Since the surfaces of bacteria are covered in uniquely patterned capsular polysaccharides, vaccines targeting these polysaccharides have become a popular field of research for protection against pathogenic bacteria. Though licensed polysaccharide vaccines are commercially available, they lack the efficiency to protect patients that are immunocompromised or at high risk because they elicit T cell independent immune responses, resulting in low-affinity antibodies. To elicit a T cell dependent response and thereby recruit B cells that produce high-affinity antibodies, a vaccine was …

Investigating The Use Of Translational Methods To Characterize Therapeutic Interventions In Models Of Pulmonary Disease, Ashley Rae Chang Jun 2023

Investigating The Use Of Translational Methods To Characterize Therapeutic Interventions In Models Of Pulmonary Disease, Ashley Rae Chang

Theses and Dissertations

Idiopathic Pulmonary Fibrosis (IPF) is an interstitial lung disease with no known cause or cure. IPF has an incidence of 75/1,000,000 of the population, predominately in men over the age of 60. This relatively rare disease develops in a chronic and progressive way, ultimately leading to death within two to five years of diagnosis. Our use of translatable methodologies in the bleomycin mouse model of IPF led to the novel identification of the similarities between the average percent loss of lung function in previous human clinical trials to that of our mouse model data. There is no treatment for IPF …

Developing Microfluidic Devices For Biomolecule Analysis, Jacob Brent Nielsen Jun 2023

Developing Microfluidic Devices For Biomolecule Analysis, Jacob Brent Nielsen

Theses and Dissertations

Microfluidics can take laboratory processes and miniaturize them, which led to the term lab-on-a-chip. Microfluidic devices are fabricated with a variety of materials and methods, each offering distinct advantages for bioanalysis. This dissertation describes two methods to create these devices, with the use of four different materials to achieve different assay needs. In the first application in this dissertation, hot-embossed cyclic olefin copolymer was used to create microdevices to electrophoretically separate seven preterm birth biomarkers. One biomarker, thrombin-antithrombin III, cannot be purchased commercially so I developed methods for its assembly in the lab. Dot blots and mass spectrometry were used …

Context Dependence Of Non-Covalent Interactions Among Amino-Acid Side Chains Along The Solvent-Exposed Surface Of Coiled Coils, Kimberlee Larsen Stern Jun 2023

Context Dependence Of Non-Covalent Interactions Among Amino-Acid Side Chains Along The Solvent-Exposed Surface Of Coiled Coils, Kimberlee Larsen Stern

Theses and Dissertations

Coiled coils are a well-known protein structure prevalent in eukaryotic function, synthetic applications, and de novo protein design. Coiled-coil folding is often described using heptad repeat positions labeled abcdefg where a and d positions occupy the interface between the coils, e and g positions flank the interface, and the b, c, and f positions face the solvent-exposed surface. The a, d, e, and g positions have been extensively studied in the coiled-coil literature. There is a lack of investigation on the impact of the b, c, and f positions on coiled-coil folding. Chapter 1 is an introduction to the heptad …

Soft Contact Lens Tear Film Proteomics For Clinical Diagnostic Biomarker Discovery, Robert Kimball Roden Jun 2023

Soft Contact Lens Tear Film Proteomics For Clinical Diagnostic Biomarker Discovery, Robert Kimball Roden

Theses and Dissertations

Human tear film is an accessible biospecimen rich with useful biological information. As tear protein biomarkers for both ocular and systemic diseases have been identified in tears, efforts are being made to create point-of-care tests useful for clinical diagnoses. However, there are significant obstacles to tear diagnostics, including inadequate sampling methods and biomarkers with insufficient sensitivity and specificity. Furthermore, tear film diagnostics are particularly challenging for dry eye disease (DED) patients, where low tear volume makes sampling more difficult and the multifactorial nature of DED makes identifying the exact pathological subtype very complex. As soft contact lenses (SCLs) are designed …

Cesium Voltilization In Lif-Bef2: Predicting Release In The Event Of Fhr Fuel Failure, Johnny Hedrick Williams Jun 2023

Cesium Voltilization In Lif-Bef2: Predicting Release In The Event Of Fhr Fuel Failure, Johnny Hedrick Williams

Theses and Dissertations

This work demonstrates how ICP-MS can be employed to evaluate cesium volatilization from LiF-BeF2 (Flibe) salt with ab initio molecular dynamics studies used as corroborating data to better understand cesium behavior. Using mixtures of Flibe with 2 mol% CsF, it was found that cesium was stable within the salt melt at temperatures between 500-650°C over a time span of 8 hours. At 800°C, cesium vaporized from the salt at a rate of 0.83% / hr with a mass flux of 0.0023 g Cs / cm2hr. The atomistic modeling results show poor solvation of Cs at 500°C and 800°C, with stability …

The Performative History Of Tomboys In Anglophone Literature Prior To Little Women, Kimber Palmer Jun 2023

The Performative History Of Tomboys In Anglophone Literature Prior To Little Women, Kimber Palmer

Theses and Dissertations

This paper examines the expansive history of literary tomboys in the century preceding Louisa May Alcott's Little Women (1868). Applying concepts from gender performativity theory, it explores earlier and previously overlooked portrayals of tomboys (or, alternatively, "hoydens" or "romps"), especially in Richard Brinsley Sheridan's A Trip to Scarborough (1777), Isaac Bickerstaffe's The Romp; A Comic Opera in Two Acts (1786), Mary Wollstonecraft's A Vindication of the Rights of Woman (1792), Jane Austen's Northanger Abbey (1817), and E.D.E.N. Southworth's The Hidden Hand (1859). Because the tomboy phenomenon emphasizes that gender roles must be learned and can be resisted, tomboy characters are …

Exploration Of The Impact Of Gender-Affirming Care And Social Support On Executive Functioning And Mental Health In Gender-Diverse Autistic And Non-Autistic Adults, Karys Michaela Normansell-Mossa Jun 2023

Exploration Of The Impact Of Gender-Affirming Care And Social Support On Executive Functioning And Mental Health In Gender-Diverse Autistic And Non-Autistic Adults, Karys Michaela Normansell-Mossa

Theses and Dissertations

Between 4.8% and 26% of adults presenting to gender dysphoria clinics have an autism diagnosis. Both autistic people and gender-diverse people have higher rates of mental health conditions including anxiety and depression and more difficulties with executive functioning, all of which impact quality of life. Some work suggests that gender affirmation leads to better mental health outcomes, including better executive functioning, but this has not been studied directly in autistic adults who identify as gender-diverse or transgender. As such, we elected to explore the relationships among these variables at this intersection of gender diversity and autism. In a sample of …

Visions Of Mary: Patria As The New Mestiza Madonna In Alvarez's In The Time Of The Butterflies, Mila Argueta Jun 2023

Visions Of Mary: Patria As The New Mestiza Madonna In Alvarez's In The Time Of The Butterflies, Mila Argueta

Theses and Dissertations

Alvarez’s In the Time of the Butterflies is a fictional depiction of three sisters who are lauded for their role in ending the supremacist, womanizing, and terror-inspiring reign of Trujillo. While, one character, Patria, seems to represent the traditional, and at times cloistered, life of a Dominican wife and mother (reflecting the Malinche and sufrida archetypes), the text also shows her transformation into one of the most vital figureheads of the revolution. I find that when she joins the revolution, she comes as a transformed Marian-figure. Unlike Ibez Gomez Vega and other feminist scholars who have categorized Patria as one …

Silver Sagebrush (Artemisia Cana) Survival And Regrowth After Fire In The Mixed Grass Prairie, Marcus A. Comfort, Eric G. Lamb

Western North American Naturalist

Silver sagebrush (Artemisia cana) is a low shrub species that is common in northern mixed grass prairies and that provides important wildlife habitat. Silver sagebrush habitat has historically experienced frequent wildfires, but postsettlement fire control efforts have reduced fire frequencies. The effects of fire on silver sagebrush growth and regenera­tion are not clearly understood; this study examined the effects of fire on silver sagebrush regeneration by evaluating post­fire plant size and distribution data from one season. Sites were located in the northern mixed prairie in Saskatchewan, Canada, and included pastures where the plant community was recovering from both …
