Natural Variation Of Fructose-1,6-Bisphosphatase In Colias Butterflies, Andrea Blair Stokes

Theses and Dissertations

In a process known as the evolutionary recursion, it is possible to follow how adaptation affects natural selection at successive stages of a species’ life cycle. Through studying allele and genotype frequencies of enzymes in glycolysis, a central metabolic pathway, it is possible to document how polymorphisms can shift the evolving functionality of enzymes within or among species. Fructose-1,6-bisphosphatase (FBPase) is an enzyme in gluconeogenesis that converts fructose-1,6-bisphosphate to fructose 6- phosphate. It is also known to convert the unused amino acid carbon skeletons of glycolysis into glycogen storage. Appearing to play a vital role in the acquisition, storage, and …

Memristive Ising Circuits, Vincent James Dowling

Theses and Dissertations

Resistance random access memory (ReRAM) cells are emerging passive components showing great promise for applications in non-volatile storage, in-memory computing, and neuromorphic circuits, to name a few. Various experimental ReRAM cells have demonstrated excellent characteristics. This includes nanoscale size, short read and write times, and small energy requirements needed to manipulate the information. The main obstacles preventing the widespread adoption of ReRAM technology are significant device-to-device and cycle-to-cycle variability.

In essence, ReRAM cells are resistors with memory whose state (resistance) can be changed by an applied signal such as voltage. Many models were developed for describing their response. These range …

The results were that the use of CRE-enriched lessons increased the engagement of grade-level students in biology, and that engagement requires a two-pronged approach – cultural …

Peromyscus Maniculatus Bairdii And Peromyscus Maniculatus Sonoriensis Polymorphisms, Matthew Dixon Lucius

Theses and Dissertations

Sequencing technology has advanced greatly over the past couple of decades. This has led to many studies developing hypotheses based on genomic data. This requires many genomic studies to have up-to-date information on the species’ or subject’s genome being investigated. If a study does not have accurate or up-to-date background information, then they cannot fully develop their theories that are being established. In this study, I utilize outbred Peromyscus maniculatus, deer mice that are genetically diverse, to record the polymorphisms that are found throughout the Peromyscus maniculatus genome. I first explore the differences between the polymorphisms found in Peromyscus …

Too Feminine For Execution?: Gender Stereotypes And The Media’S Portrayal Of Women Sentenced To Death, Kelsey M. Collins

Theses and Dissertations

Traditional gender norms prescribing women as more nurturing and less aggressive than men have led to both the reluctance to view women as capable of violence, as well as a greater willingness to execute men than women in the United States. To make sense of the instances where women are sentenced to death, the media often pathologizes and/or demonizes them. Scholars have found that demonizing and dehumanizing those executed is a necessity to the implementation of capital punishment, both in cases of male and female defendants. To better understand how the news media have framed the gender and racial narratives …

Elucidating The Interdependence Of Motor-Cognitive Development And Performance, Thomas Cade Abrams

Theses and Dissertations

As the development of complex coordination and control (i.e., motor development) involves the integration of neuromotor, psychological, social, and cognitive processes (i.e., executive functions), a better understanding of how these processes are embedded and manifest across stages of development throughout the lifespan is needed. The long-term processes associated with the acquisition and development of motor competence (MC), specifically, effortful practice and performance of various locomotor and object control skills, provide direct mechanisms for contributing to executive function (EF) development via different learning-related (e.g., synaptogenesis, hippocampal neurogenesis) as well as exercise-related (e.g., exercise-mediated neurogenesis, angiogenesis) mechanisms. However, traditional MC assessments use …

Inspiring The Imagination, Nathan Terracio

Theses and Dissertations

As someone who has been a life-long audience member and who has worked in over a hundred different theatres on countless different productions over the course of my professional career, I have always been fascinated by the process of creating art out of thin air. I have watched artists undergo careful planning only to have that work thrown out during the rehearsal or technical process, or even sometimes during the last preview performance. I have watched moments unfold on stage at the last minute with seemingly no planning or effort. I have seen the reactions of audiences to moments that …

Turning Passion Into Action: The Intersection Of Transformational Coaching And A Counter-Narrative Of Black Citizenship, Erica D. Kelley

Theses and Dissertations

This action research study explored Black middle school students’ interactions with a high-quality civics curriculum that sought to complicate traditional notions of citizenship; provide authentic opportunities for engagement and participation; center student voices; and foster positive, empowered civic identities. The study also examined whether transformational coaching, with an explicit focus on culturally responsive practices, enhanced one social studies teacher’s ability to implement such a curriculum. Critical race theory and social identity theory illuminated how traditional civics education, rooted in white supremacy, excludes and distorts Black citizenship and civic identities; conversely, both theories informed alternative views of citizenship and identity rooted …

Theses and Dissertations

The past several years have seen remarkable progress in renewable energy sources such as solar and wind, showing excellent efficiency and significant cost reduction. The intermittent nature of renewable resources requires them to be integrated with energy storage systems that can hold or convert this excess energy into other forms. Though batteries have been the most popular, it is also possible to store the energy as chemicals and fuels, such as hydrogen (H₂). Hydrogen generation from water electrolysis has been receiving significant attention in recent years. Among the existing water electrolysis technologies, anion exchange membrane electrolyzers (AEMELs) are …

The Power Of Story In Developing A Cycle Of Efficacy For Teachers And Students, Melissa Renee Ewing

Theses and Dissertations

There is scarce nationwide evidence of the impact of instruction on student achievement in the area of writing (Coker et al., 2018; Persky et al., 2003; National Assessment of Educational Progress, 2002). Standardized writing assessment has shifted to text-dependent analysis, which requires students to read and analyze a passage and then compose an essay in response to a text dependent prompt. This type of writing requires students to understand how and why authors make decisions and then support a claim with analysis. This multiple-case, action research study followed three elementary teachers as they reflected on a journey resulting in transformation …

Arctic Ocean And Subarctic Seas Dynamics In A Changing Climate, Sarah B. Hall

Theses and Dissertations

Salinity is the primary determinant of the Arctic Ocean’s vertical density stratification in the upper ocean, which has major implications on the ocean’s physical dynamics alongside a period of rapidly declining sea ice. In recent decades, the Arctic’s freshwater content (FWC) has increased as a result of the accumulation of freshwater source inputs. Additional freshwater exported to the North Atlantic may hinder overturning processes that are vital to the regulation of global climate. This dissertation employs in situ measurements, satellite observations, and ocean model simulations to better understand salinity and freshwater changes in the Arctic Ocean during this changing climate. …

Speculative Pasts: American Historical Fiction In An Age Of Empire, Gregory William Deinert

Theses and Dissertations

This study identifies a new generic form termed here the “Speculative Historical Novel” within contemporary American fiction. The works that Speculative Pasts collect all agonize over the erasure of the past, and question how we can incorporate history into the present while accepting that full recuperation may be impossible. In their emphasis on the erasure of the past, these novels trace the manifold silences created by the imperial conquest of the New World and articulate how this past continues to structure the lived experiences of everyone on this continent.

This speculation is, on the one hand, necessarily suppositional. When faced …

Embodied Participation In Digital Publics: Somnambulance, Surveillance, And The Construction Of Identity, Adam S. Padgett

Theses and Dissertations

In our current information landscape, routine surveillance has changed the nature of rhetorical engagement in public spheres. Scholarship in publics theory have done productive work to map out the complex field of discursive participation. Michael Warner has demonstrated how, through the circulation of common texts, people no longer have to be in public in order to participate in publics. However, in the wake of ubiquitous surveillance, this focus on publicness has offered little attention to privacy in publics theory. I argue that legal and postmodern theories of bodies-as-texts is problematic for reading and writing bodies online. Intersecting with embodiment and …
