Building A Framework For Analyzing Non-Linear And Multidimensional Kinetics, Mainak Dhar

Theses and Dissertations

Many materials exhibit multiple rates of molecular relaxation due to structural complexities. Standard linear and one-dimensional kinetic cannot extract all the necessary dynamic information about these systems. This dissertation contributes to an overarching scheme to develop new non-linear and multidimensional kinetic experiments to obtain this information. The studies span computation and experiments, picosecond to second timescales, and both single-molecule and pulsed-laser kinetics

Single-molecule kinetics experiments yield time series that contain information about unique structural and dynamic properties of materials. However, these time series are noisy, and data analysis is challenging. Parametric methods are computationally intensive and require strong, unverifiable assumptions …

“A Threat To The Family”: Phyllis Schlafly And The Construction Of Negative Group Identity, Christopher Howell

Theses and Dissertations

In this dissertation, I argue that Phyllis Schlafly’s fight against the proposed Equal Rights Amendment (ERA) from 1972 to 1976 helped construct the “pro-family” political identity that opposed the ERA and came to define social conservatism in American politics. She did this through the creation and elaboration of a negative group identity: individuals defined by their desire for an imagined past of traditional, stable hierarchies. By taking an anodyne piece of legislation and framing its supporters as direct threats to the status quo, Schlafly effectively mobilized a group of previously apolitical actors towards political activism. In the process, she helped …

Creating Systems Of Professional Learning To Encourage Deep Thinking In Social Studies: A Qualitative Study, Elizabeth Poda King

Theses and Dissertations

This paper describes a problem that developed due to a lack of systems in place to provide professional learning for teachers in social studies. This problem was ignited when revised standards were adopted which shifted from heavy content focus to skills and content. Standards requiring both skills and content encourage student inquiry and promote deep thinking by students through the use of historical evidence. Therefore, the purpose of the improvement science plan-do-study-act (PDSA) cycles was to develop a system of job-embedded professional learning to assist teachers with teaching strategies that use historical evidence to promote deep thinking in social studies …

Generalized Sierpiński Numbers And New Irreducibility Criteria On Legendre Polynomials, Robert Scottfield Groth

Theses and Dissertations

A Sierpiński number is an odd positive integer k such that k·2n +1 is composite for all n ∈ Z+. Similarly, a Riesel number is an odd positive integer k such that k · 2n − 1 is composite for all n ∈ Z+, and a Brier number is a number that is both Sierpiński and Riesel. In this dissertation, we consider a generalization of a Sierpiński number and establish their existence by showing, for every fixed A ≥ 2, there are infinitely many odd positive integers k such that the k · an + 1 is composite for every …

Merit, Equity And Intersectionality: Autoethnographic Examination Of Perceived Race And Gender-Based Discrimination In The Workplace, Shavanna Henry

Theses and Dissertations

This autoethnographic action research dissertation uses intersectionality, critical race theory, and racial battle fatigue theoretical lenses to examine my mental health as I experienced perceived race-based and gender-based discrimination at a public high school on the West Coast of the United States. The goal was to examine how my mental health was impacted during the development and attempted implementation of a DEI plan, and how my mental health was affected by the intersectionality of race and gender. I used journal entries and digital artifacts to craft seven vignettes that captured my experience. The findings from coding and analyzing data showed …

The Influence Of Instruction On Underrepresented Stem Leaders On Elementary Students’ Stem Identity And Perceptions Of Stem, Megan Elizabeth Willson

This action research study explored the influence of exposure to underrepresented STEM leaders on third-grade students’ STEM identity and their interest in STEM careers. Using an integrative STEM approach and guided by both Constructivist Learning Theory and Social Cognitive Career Theory, this convergent mixed methods study consisted of an eight-week intervention with lessons based on different STEM leaders and related activities each week. This eight-week period collected data through weekly researcher field notes, exit tickets and was prefaced and followed by a pre- and post-survey and pre- and post-interviews. Findings from the quantitative data, the Role Identity Survey in STEM …

Systems Check: A Qualitative Case Study Of Educators And Parent-Educators Supporting Adolescent Readers From An Ecological Systems Perspective, Kristi Nicole Grooms

Theses and Dissertations

In spite of decades of research and an abundance of well-intentioned intervention efforts, supporting adolescent readers, particularly at the middle level, remains a significant area of concern for educators in the United States. The struggles are present for educators working to help underperforming readers reach grade-level and keep advanced readers motivated and engaged. At home, parents and guardians experience similar challenges. Data on adolescent comprehension performance continues to be frustrating in terms of producing consistent positive results. This qualitative action research study investigated the ongoing challenge of supporting adolescent readers, specifically within the context of 7th grade, through a systems …

Extracting Metamorphic Histories Utilizing U-Pb Laser Ablation Zircon Geochronology From The Southern Appalachians Crystalline Rocks And Detrital Sediment, Meredith Kay Love Gawai

Theses and Dissertations

The southern Appalachian mountain belt is an accretionary orogen that formed in the southeastern United States through several phases of oceanic subduction and continental collision during the Paleozoic Era and culminated in the formation of the supercontinent Pangaea. Although many U-Pb zircon ages have been collected from the igneous, metaigneous and metasedimentary rocks in the crystalline core of the southern Appalachians, there remain opportunities to better reconstruct the metamorphic and magmatic history of the southern Appalachians through the lens of zircon geochronology. Such data are valuable in identifying genetic relationships between candidate terranes of the orogen. Herein, I present laser-ablation …

Displaced Decarbonization: Climate Necropolitics And The Contested Spatialities Of Green Hydrogen In Namibia, Meredith J. Deboom

Faculty Publications

Green hydrogen is often presented as a transformative solution to the dual challenges of decarbonization and economic development. This article applies the framework of climate necropolitics to interrogate the contested spatialities underlying such “win-win” narratives. It does so through an extended case study of Hyphen Hydrogen Energy, a $10 billion green hydrogen project planned for Lüderitz, Namibia. A remote town of 20,000 in a country with a $12 billion annual GDP, Lüderitz initially appears to be an unlikely host site for the “industrial fuel of the future.” To explain this outcome, I first illustrate how discordant socio-spatial projects—including European energy …

Two-Layer Formulation For Long-Runout Turbidity Currents: Theory And Bypass Flow Case, Hongbo Ma, Gary Parker, Matthieu Cartigny, Enrica Viparelli, S. Balachandar, Xudong Fu, Rossella Luchi

Faculty Publications

Turbidity currents, which are stratified, sediment-laden bottom flows in the ocean or lakes, can run out for hundreds or thousands of kilometres in submarine channels without losing their stratified structure. Here, we derive a layer-averaged, two-layer model for turbidity currents, specifically designed to capture long-runout. A number of previous models have captured runout of only tens of kilometres, beyond which thickening of the flows becomes excessive, and the models without a lateral overspill mechanism fail. In our framework, a lower layer containing nearly all the sediment is a faster, gravity-driven flow that propels an upper layer, where sediment concentration is …

Removing Eog Artifacts From Eeg Recordings Using Deep Learning, Christian O'Reilly, Scott Huberty

Faculty Publications

The electroencephalogram (EEG) directly measures the electrical activity generated by the brain. Unfortunately, it is often contaminated by various artifacts, notably those caused by eye movements and blinks (EOG artifacts). Such artifacts are usually removed using an independent component analysis (ICA) or other blind source separation techniques. However, it is difficult to assess whether subtracting EOG components estimated through ICA removes some neurogenic activity. It is crucial to address this question to avoid biasing EEG analyses. Toward that objective, we developed a deep learning model for EOG artifact removal that exploits information about eye movements available through eye-tracking (ET). Using …

Open Accessarticle Crystal Plasticity Modeling Of Dislocation Density Evolution In Cellular Dislocation Structures, Md Mahabubur Rohoman, Caizhi Zhou

Faculty Publications

The complex thermal cycles during the solidification process in metal additive manufacturing (AM) lead to the formation of high-density dislocation networks, organizing into submicron-scale cellular structures. These ultrafine structures are recognized as crucial for enhancing the mechanical properties of AM metals. In this study, we investigate the evolution of dislocation density within these cellular structures under plastic deformation and its impact on mechanical response using dislocation density-based crystal plasticity finite element (CPFE) modeling. The model incorporates the evolution of both statistically stored dislocation (SSD) and geometrically necessary dislocation (GND). Our simulations reveal that the yield and flow stresses of dislocation …

Representation Of South Asians In U.S. American Children’S Picture Books, Eman A. Chaudhry

Senior Theses

One potential cause of racism against South Asian Americans in school could be the lack of authentic representation of South Asians in the media. A method to properly depict them is via children’s picture books, which can be used to explore different cultures within the classroom. I examined the current landscape of American children’s picture books that depict South Asians and found that the most authentic portrayals included characters embracing certain holidays or traditions. Additionally, I researched issues that affect the South Asian community, one of which includes the stigmatization of mental health. Drawing on my own experiences, I wrote …

Frenemies? Fascists And Conservatives In Interwar Britain, Dylan R. Cameron

Senior Theses

This thesis examines the attitudes, beliefs, and arguments of British Conservatives (Tories) in discussions about British fascism through the lens of two mainstream Conservative newspapers, The Daily Telegraph and the Daily Mail, focused primarily on the buildup and aftermath of the infamous Olympia rally in June 1934. This thesis identifies two key factions within the conservative movement which arose in reaction to the rise of Oswald Mosley’s British Union of Fascists (BUF): (1) the staunchly anti-fascist “mainline Tories” who detested the BUF’s “foreign” character, propensity for violence, and antithesis to traditional liberal democratic principles, and (2) the fascist-sympathizing “reactionary Tories” …

Vital Language Practices And Attitudes Among The Lumbee, Deven A. Hull

Senior Theses

The longstanding interest among linguists and linguistic anthropologists in Indigenous languages has increasingly adopted a Critical Indigenous framework, which has been promoted by Indigenous scholars and community leaders as a means of decolonizing “salvage” collection of Indigenous language materials. An important aspect of Critical Indigenous theory is the framework of vitality—that is, an emphasis in literature and community practice on the everyday living and lived elements of culture. One means of promoting Indigenous language within this Critical framework of vitality that is community-centered is centering vital language practices in community-based archives, which seek not to document the language as it …

A Theoretical Defense Of Police Recalibration In Columbia, South Carolina, Sanya Singh

Senior Theses

This paper defends police recalibrationism as the best means of reforming law enforcement. Columbia, South Carolina, will serve as a case study to demonstrate the philosophical and practical justifications of recalibrationism. Police recalibration, which aims to reconceptualize the role of police by reallocating extraneous responsibilities to other entities, offers a more comprehensive and viable solution than abolition, fiscal restraint, and managerialism. The paper further examines proposals that align with police recalibrationism through the lens of the philosophical frameworks of social contract theory and utilitarianism to demonstrate how the reform would fulfill the proposed goals of the American criminal justice system. …

The Stigma Surrounding Sex And Sexuality In American Culture, Sophia L. Pollock

Senior Theses

An important question to examine is the origin and implications of the taboo against sex and sexuality. The stigma against these topics encourages negative public health implications like poor sex education, high rates of sexually transmitted infections, and teen pregnancy. History of sexual stigma was examined through physical media and digital articles from the Thomas Cooper Library databases. The background and global perspective of these stigmas are covered, examining how past and distant cultures deal with sex. How sex is portrayed in the media, why a healthy sex life is important, and the subject of sex education are also addressed. …

Could It Be Cold War? How Sino-American Tensions Are Unfolding In The South Pacific., Peter R. Caldwell

Senior Theses

This thesis assesses the impacts of geopolitical competition between the United States and China, focusing on the South Pacific as a primary theatre for this great power contest, and investigating the uses of foreign aid by regional powers to effect both the geopolitical alignment and domestic policies of the developing states of the South Pacific. This paper finds that foreign aid to these South Pacific States is geopolitically motivated, and induces greater attention from competing regional powers, furthering the ongoing competition. This paper first provides an overview of the evolving political situation in Kiribati, a Pacific Island Country which has …

Endothelial Dysfunction Promotes Age-Related Reorganization Of Collagen Fibers And Alters Aortic Biomechanics In Mice, Liya Du, Jeffrey Rodgers, Nazli Gharraee, Olivia Gary, Tarek Shazly, John F. Eberth, Susan M. Lessner

Faculty Publications

Endothelial dysfunction, defined as a reduction in the bioavailability of nitric oxide (NO), is a risk factor for the occurrence and progression of various vascular diseases. This study investigates the effect of endothelial dysfunction on age-related changes in aortic extracellular matrix (ECM) microstructure and the relationship between microstructural adaptation and the mechanical response. Here, we used groups of NOS3 knockout (KO), NOS3 heterozygotes (Het), and wild-type (WT) B6 mice (controls) to study changes in hemodynamic parameters, collagen fiber organization, and both active and passive aortic mechanics using biaxial pressure myography over a time course from 1.5 to 12 mo. Our …

Tobacco Package Health Warnings About Product Manipulations: An Experimental Study Among Australian Adults Who Smoke, Emily Brennan, Claudia Gascoyne, Kimberley Dunstone, Amanda Vittiglia, Gayathri Srinivasan, Jim Thrasher Ph.D., Ma, Ms, Janet Hoek, Melanie Wakefield, Sarah Durkin

Faculty Publications

The tobacco industry manipulates cigarettes to provide sensory cues that mislead people who smoke. We assessed the effectiveness of health warnings (HWs) focussed on the impact of misleading product attributes, including filter ventilation, menthol, and roll-your-own tobacco, which were called Product Attribute HWs. Australian adults who smoke (n = 2544) were randomly assigned to view: control medication warnings; new Standard HWs with smoking harm images; Product Attribute HWs; or Product Attribute HWs plus a video. At baseline, participants were exposed to seven condition-specific warnings (+ video for those in the Product Attribute HWs + Video condition), then they were …
