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 …

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 Proposal For The Development Of A Minimal Viable Product (Mvp) Repository Website Containing Authentic Texts In Video Format For The Use Of Language Teachers In The Twenty-First Century, Rute Maria Baptista

The Novel Protein Crystallization Chaperone Telsam Stabilizes Weak Crystal Contacts, Accelerates Crystallization Of Fused Target Proteins, And Solves The Crystallographic Phase Problem, Supeshala Dilrukshi Sarath Nawarathnage

Theses and Dissertations

We studied the usefulness of genetic fusion to TELSAM polymers as an effective protein crystallization strategy. We observed novel properties in crystals of two TELSAM-target protein fusions. TELSAM as a crystallization chaperone shows rapid crystallization when it's fused to target proteins and possibly with a greater propensity. Some TELSAM-target fusions crystallized more rapidly than the same target protein alone. TELSAM-target proteins can be crystallized at relatively low protein concentrations such as 0.1 mg/mL. TELSAM requires no TELSAM polymers touching one another in the crystal lattice in order to form well-diffracting crystals. This lack of crystal contacts has not been observed …

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 …

Aiding Semantic Memory Creation With Navigational Context, Thomas Benjamin Lyle Wasden

Theses and Dissertations

While we have traditionally understood the hippocampus to be involved in memory and navigation, it also appears that it has a role in language processing, creation and prediction. An obvious explanation for this is that language is impossible if linguistic signs cannot be remembered and retrieved. Because linguistic signs are definitionally biologically neutral or arbitrary, we must use the brain's apparatus for learning and storing information from the external world to store and retrieve them. Although plausible, this explanation fails to take into account the hippocampus' role in navigation as a contributing element in the processing, storage and retrieval of …

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 …

Reading Fluency Development And Science In A Fourth Grade Dual Language Immersion Classroom, Talia A. Casares

Theses and Dissertations

Students from dual language immersion (DLI) classrooms are required to learn the language through content. However, some students have not yet developed these abilities by the time they start fourth grade. Thus, to fully comprehend content such as science, students need stronger reading and writing abilities in the second language (L2). To help stakeholders have a better understanding on how to effectively help students throughout this process, this action research studied the effectiveness of integrating literacy with science and mobile assisted language learning (MALL). Findings showed that the integrations of literacy, science and MALL were effective with statistically significant results …

How She Sleeps At Night, Alexandra Malouf

How She Sleeps at Night is a collection of lyric poetry constellated around experiences of disability, trauma, and womanhood. A critical essay introduces the collection by elucidating the experiences and theoretical underpinnings that shaped the body of these poems. The introductory essay distills the principles that informed my cardinal poetic goals as I wrote: to create poems that can be read again and again over a lifetime, which connect with readers' common humanity, and which acknowledge the nuances and complexities of being alive.

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 …

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 …

How Lucretius Uses Epic, J. Dean Murphy

Theses and Dissertations

I argue that Lucretius uses conventions of epic poetry and changes them to support his philosophical teachings. The proem of De rerum natura can be used to show how this occurs. The key moments within the proem include the invocation to Venus, how Venus is described as maternal and creative, the usage of socia to ask Venus for aid, the episode between Venus and Mars, and the establishment of Epicurean physics. I argue that the purpose of changing the expected conventions of epic is to better frame Lucretius' key idea of the purpose of life, namely reproduction.

"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, …

Local Adaptation Of Blue Penstemon: Molecular And Morphological Characterizations Of A Potential Restoration Species For The Northern Basin And Range And Snake River Plain, Jason Mark Stettler

Theses and Dissertations

Penstemon is one of North America's largest endemic genera with over 280 described species. These species are distributed throughout most of North America from the Arctic northern latitudes to tropics of Central America. The genus has historically been divided into six subgenera, but has recently been reorganized into two subgenera following some recent phylogenetic studies. I made a comprehensive assessment of the Penstemon genus' geographic distribution utilizing herbaria databases by ecoregion to discuss the general ecologic adaptations of each historic subgenera. I also assessed the Penstemon genus' bee pollinator diversity utilizing online databases of bee specimen collections associated with Penstemon …

Russell Means' Use Of The Universal Ecosystem Metaphor As An Act Of Indigenous Resistance, Clarissa Mcintire

Theses and Dissertations

Studies of American Indian protest rhetoric often define American Indian opposition either by its resistance or its conformity to non-Native institutional discursive norms, suggesting that only one of the two can be considered authentic to American Indian cultures and identities. Addressing this debate, this thesis examines an instance of Native opposition which successfully blends the two approaches: Russell Means' 1989 statement to the United States Senate. Means employs the mode of story to effectively shift discursive authority from the Senate committee members to pan-Indigenous peoples. I call this shift rhetorical occupation, or the appropriation of rhetorical space. Through rhetorical occupation, …

Hybrid Suspension Tissue Engineering Of A 3d Alveolar Model For Lung And Vascular Disease Modeling, Jonard Corpuz Valdoz

Theses and Dissertations

Tissue engineering is a dichotomy of scaffold-based and scaffold-free cultures. Scaffold-based cultures form highly organotypic structures but with low uniformity and throughput. Conversely, scaffold-free cultures create consistently sized and shaped cell aggregates with limited spheroid-like structure and function, thus restricting their use for accurate disease modeling. We hypothesized that combining aspects of each culturing format, we would produce highly organotypic structures of consistent size and shape for use in pulmonary modeling. First, to improve on culture consistency and output, we created a novel easily scalable, minimalistic design for a micropatterned hydrogel dish that increases reliability and efficiency in 3D cell …

Redistributing Cultural Capital: Graduate Programs In Wind Conducting At Historically Black Universities; Toward An Alternate Future, Jamaal William Nicholas

Theses and Dissertations

The visibility and popularity of marching bands at Historically Black Colleges and Universities (HBCUs) represents a multi-generational tradition of marching and musical excellence. With performances that reach national and international audiences through large viewership, HBCU marching band culture is elevated to artistic prominence with each major league sporting event performance, Presidential inaugural parade, and viral retweet of a performance by a recording artist. After decades of significant contribution to instrumental music education, however, HBCUs have been unilaterally unable to develop graduate programs in wind conducting. Using a qualitative study design, the goal of the current study was to identify challenges …

Screwball, Alexandra Mayer

Theses and Dissertations

This manuscript of poems explores Sephardi Jewish identity within the American diaspora. As the speaker attempts to make sense of herself and of her Jewishness in relation to her ancestry, she feels increasingly at odds with the Ashkenazi cultural practices picked up during her childhood in New York City. The poems grapple with questions such as: what Jewish culture belongs to whom? Who do bagels belong to? Who does Phillip Roth belong to? When Jewishness is not based in religious practice, what is it? Is it possible for a Sephardi Jew in America to disentangle themselves from Ashkenazi production? How …

Psychophysiological Biomarkers Of Concussion Recovery, Adam Todd Harrison

Theses and Dissertations

Each ach year a growing number of individuals report lingering deficits months-years following concussion. Persistent post-concussion symptoms (PPCS) can negatively impact day-today activities and if left untreated may manifest in severe neurological sequelae resulting in long-term cognitive impairment or advanced neurological degeneration (i.e., CTE). Current clinical diagnostic and prognostic assessments (e.g., symptom reports and neurocognitive testing) lack the sensitivity to quantify neurological function. Accordingly, there is a critical need to identify objective biomarkers specific to PPCS to improve an individual’s quality of life and prevent severe long-term neurological dysfunction.

Psychophysiological measurements (e.g., EEG derived event-related potentials, heart rate variability, and …

Perspectives About Food Safety In Diverse Low- And Middle-Income Countries, Sejla Isanovic

Theses and Dissertations

Concerns about unsafe food influence food choice, and consumption of unsafe foods increases morbidity and mortality, particularly in low- and middle-income countries. Actions to ensure safety of food are dominated by mitigation of biological and chemical hazards through supply-side risk management, disregarding individuals’ experiences and perspectives of food safety. We aimed to identify and categorize perspectives about food safety in five countries. Five Drivers of Food Choice projects provided transcripts from 17 focus groups discussions and 303 interviews in Kenya, Ghana, India, Guinea, and Vietnam. We analyzed transcripts using a priori and emergent codes. Individuals constructed meaning about food safety …

Inheritance And Appropriation: Confronting Privilege In Magical Young Adult Fiction, Natalie Jipson

Theses and Dissertations

This thesis investigates the way that magical ability and the lack thereof has been racialized through the deployment of blood-based models of inheritance in young adult fantasy literature. Because of the connection between blood and biology, texts that only allow magical transmission from parent to child place significant limits on who can access witchery, creating systems of privilege that enforce racial and classed hierarchies. I will use magical novels written by Laurie Forest, Graci Kim, Nnedi Okorafor, Amy Rose Capetta, and Daniel José Older to illustrate the hierarchies created by blood-based models, as well as to demonstrate the possibilities that …

Three Essays On Banking And Other Financial Institutions, Xiaonan Ma

Theses and Dissertations

This paper shows that access to payday lending affects societal health outcomes such as opioid-related mortality. I find that states allowing payday lending experience 1.5 lives lost per 100,000 population every year, which amounts to one-third of its mean value. I interpret this result in line with the increased consumption of opioid pills after accessing to payday lending. Accordingly, the effects are more pronounced in areas with low socioeconomic status. Confounding events, time trends, or systematic differences between states allowing and prohibiting payday lending are unlikely to explain the association between payday lending access and opioid mortality. Overall, my findings …

Understanding The Genomic Influence And Virulence Capabilities Of Environmentally Isolated Vibrios, Shannon Elizabeth Pipes

Theses and Dissertations

The genus Vibrio consists of Gram-negative bacteria that possess a curved rod shape and are routinely isolated from estuarine and coastal salt water. Vibrio cholerae, Vibrio parahaemolyticus, and Vibrio vulnificus are the major three species that contribute to human disease worldwide, and a variety of other Vibrio species contribute to persistent problems in the aquaculture and fishing industries. The CDC estimates that vibrios cause 80,000 cases of disease each year in the United States alone, however, this number is thought to be underestimated, since some disease is only self-limiting, meaning patients may not seek medical treatment and have …

From Gene Expression To Physiology: A Study Of Chronic Thermal Tolerance In The Mytilus Edulis Species Complex, Lindsey Cate Schwartz

Theses and Dissertations

Rising ocean temperatures are a severe and ever-present threat to marine life. With environmental temperature having such a large impact on organismal performance, understanding the mechanisms which contribute to the ability to survive at higher temperatures is a crucial research focus. Significant progress has been made in discovering these mechanisms on the cellular, biochemical, and physiological levels, but is it much less common for those to be examined together. Using the Mytilus edulisspecies complex as a model system, this dissertation takes a closer look at how prolonged exposure to sub-lethal high temperatures impacts marine organisms on multiple levels of …
