Density Anomaly Leads To Rift Initiation: Quantifying Active Rifting And Comparison To The East African Rift Zone, Chloe Boucher

Graduate Student Theses, Dissertations, & Professional Papers

Active rifting, elastic failure in the lithosphere from rising density anomalies in the mantle, is fundamental to the Wilson Cycle which describes the cycle of tectonic plates. Active rift zones are common in the oceanic lithosphere but are less common in the thicker continental lithosphere. The current largest active continental rift zone is the East African Rift Zone (EARZ). Although active rifting is fundamental to plate tectonic theory, the mechanics and parameters needed for a density anomaly to initiate a rift have not been undertaken. This model aims to solve the problem of a density anomaly initiating a continental rift …

Where The Framework Ends: Equity Considerations And Limitations During Agency River Permit Allocation Decision Making Processes, Kelsey Ellen Phillips

Graduate Student Theses, Dissertations, & Professional Papers

River recreation in the U.S. increased dramatically in the 1970s as boating technology and recreational skill level shifted, thus a number of federally- and state-managed river areas instituted use limits over the years to prevent the environmental and social impacts perceived to have stemmed from increased use. These river managers were then faced with the task of allocating this use between private and commercial users (allotment) and within these groups (rationing), complicated by the fact that members of the public perceive equity differently. Early recreation use allocation research explored how different rationing techniques favor different groups, for example those with …

“We’Re Left Picking Up The Pieces:” Use Of Grief Interventions In Rural Schools Since Covid-19 Pandemic, Jennifer Lynn Rotzal

Graduate Student Theses, Dissertations, & Professional Papers

Research has indicated that individuals who have died from the COVID-19 virus will likely leave behind several grieving family members. For every person who dies of COVID-19, it was estimated that they would leave behind 2.2 children and 4.1 grandchildren (Albuquerque & Santos, 2021). The death of a parent or other loved one is often noted as one of the most potentially traumatic experiences for a child. During the COVID-19 pandemic, death became more prominent in hundreds of thousands of children’s lives, having a profound effect on the child, as well as on their family and surrounding community (Griese et …

The Other Identity Politics: Political Turning Points And Political Identity Development In College-Going Emerging Adults, Kaetlyn Jeanette Cordingley

Graduate Student Theses, Dissertations, & Professional Papers

Emerging adulthood is a critical developmental period, especially for identity– the development of our sense of who we are internally and relative to others. This research sought to investigate one understudied aspect of identity development: political identity. Five questions guided this research: first, is political identity related to broader identity development? Second, does political identity development differ based on political ideology (liberal, moderate, conservative)? Third, do individuals’ self-identified political turning point events differ based on political ideology? Fourth, how is political identity development related to political turning point narratives? Fifth, how does meaning making interact with political identity development and …

Zooming In On A Snapshot Of Care: Adapting The Index Of Care For Historical And Modern Individuals In The Terry Collection, Felicia Robyn Sparozic

Graduate Student Theses, Dissertations, & Professional Papers

This dissertation adapts the Index of Care (IOC), traditionally focused on prehistoric contexts, to historical (1840-1950) and modern (post-1950) individuals from the Smithsonian’s Terry Collection, to account for those individuals with extensive records. By introducing sister methodologies for both historical and modern contexts, this research bridges the methodological gap in care analysis, enhancing the original IOC with contextual environmental variables and, for modern individuals, DNA analysis.

The study utilizes a selected cohort from the Terry Collection, emphasizing the investigation of caregiving practices across different sexes and ancestral backgrounds. Contrary to initial hypotheses predicting sex-based differences in care provision, findings show …

Csn-5: A Tumor's Friend Or Foe In The C. Elegans Germline?, Kellie C. Kuch

Graduate Student Theses, Dissertations, & Professional Papers

The COP9 signalosome is a highly conserved eukaryotic complex regulating protein degradation via deneddylation of Cullin-RING E3 ligases. CSN5, the COP9’s fifth component, contains the catalytically active domain for CSN deneddylation. The complex is inactive without CSN5; however, CSN5 engages in COP9-independent binding with several other proteins, typically promoting either destruction or stabilization of its partners. Many of its confirmed interaction partners are also implicated in tumorigenesis (prominent examples being p27 and p53) and a complex cancer interactome has been established for CSN5. Additionally, CSN5 overexpression has been documented in a staggering array of cancers of diverse origins. This discovery …

Farey Recursion And Hyperbolic Dehn Filling, Jose Ebenezer Martinez

Graduate Student Theses, Dissertations, & Professional Papers

In this work, we present a solution to William Thurston's edge gluing equations for Dehn fillings of hyperbolic 3-manifolds. This is done for triangulations that involve the layered solid torus. Our approach uses Farey recursive functions, and we present a Farey recursive function that provides a solution to the gluing equations for any hyperbolic Dehn filling admitting a triangulation by the layered solid torus. We provide examples that demonstrate our solution for multiple 3-manifolds, and study the roots of the corresponding Farey recursive polynomials. As an additional application of our solution, we provide a formula for the complex length of …

The Influence Of Sex Hormones On The Physiological Response To Exercise In Females, Katherine Sue Christison

Graduate Student Theses, Dissertations, & Professional Papers

The overall aim of this dissertation was to investigate the influence of female sex hormones on the response to exercise in premenopausal and postmenopausal women. Study one examined the effect of menstrual cycle phase on thermoregulation during prolonged exercise in the heat. Notably, elevated core temperature and basal aldosterone was apparent in the mid-luteal phase corresponding with elevations in estrogen and progesterone. Aldosterone significantly increased following exercise in the heat but remained elevated in the mid-luteal phase, suggesting a previously unexplored menstrual phase-aldosterone hormonal additivity under the stress of uncompensable heat. Study two was a survey-based investigation with the aim …

Foreign Expert: A Memoir Manuscript, Jenny L. Rowe

Graduate Student Theses, Dissertations, & Professional Papers

This is a full memoir manuscript that I wrote for my MFA thesis, which is tentatively titled Foreign Expert. In this manuscript, we follow myself as narrator as I struggle to adapt to life in Beijing (prior to the pandemic) while also recovering from a recent divorce. The man I’d been married to for five years back in Iowa had become violently mentally ill, and though I’d been fortunate enough to remove myself from him, I quickly learned that being a foreign expert in China—my residential visa title—required more work than basic survival. By the end of my two years …

Menopause In The Public Sphere: The Consciousness-Raising Practices Of Technical And Experiential Experts, Emma J. Murdock

Graduate Student Theses, Dissertations, & Professional Papers

Menopause is frequently discussed through a biomedical lens, which stresses technical language and knowledge, yet emerging in popular culture is experiential experts sharing how they feel about menopause. This paper analyses Michelle Obama's podcast episode titled “What Your Mother Never Told You” (2022) featuring Dr. Sharon Malone, a medical doctor and menopause experiential expert. Using consciousness-raising and the spheres of argumentation, I analyze how the experiential and technical experts of the podcast address and speak about menopause. This paper aims to question how consciousness-raising can reconstruct the understanding of menopause through an experiential-centric lens by placing personal testimony and experiences …

No Worries, It’S Fine, Lexie E. Loader

Graduate Student Theses, Dissertations, & Professional Papers

In my MFA exhibition, no worries, it’s fine, I depict seemingly mundane objects and places in my paintings to explore underlying themes of the bittersweet. They contain both painful memories and sweet moments, and their complexity gives them authenticity. To only explore the one would be dishonest, as the bitter and the sweet are forever intertwined.

Bittersweet is tied to longing…longing for someone you love when they are not present, for better circumstances while accepting where you are. Longing can propel us forward, one step at a time. It gives us the hope that when we experience pain, the pendulum …

A Soil-Plant-Atmosphere Continuum Model To Simulate Seedling Response To Water Stress, Michael Kurt Kendree Jr.

Graduate Student Theses, Dissertations, & Professional Papers

Most current ecohydrologic models simplify the hydraulics that are at play in plant-water relationships by assuming that the water content within the plant is static. In reality, plants have a relative water content that varies with time in response to environmental stresses. To some extent, variations in plant relative water content are regulated by changes in the osmotic potential of water within plant cells, which contributes to the resilience of plants during periods of water shortage. We present a model that simulates plant water transport and storage within the soil-plant-atmosphere continuum. The model incorporates the role of osmotic regulation in …
