The Bacterial Sensing Nuclear-Oligomerization Domain 2 Receptor In The Brain: Location And Potential Function, Julia Smyth

Dissertations

Nucleotide-binding oligomerization domain-2 (NOD2) is a cytosolic receptor, activated by bacterial peptides that initiates innate immune responses through nuclear factor-κB (NF-κB), mitogen-activated protein kinase (MAPK), and Caspase-1 pathways. While the role of NOD2 in inflammation outside the central nervous system (CNS) is well-established, especially in the gastrointestinal system, its expression and function in the brain remain poorly defined. Previous genetic studies suggest a link between NOD2 and neurological and psychiatric conditions, including stroke, Parkinson’s disease, and schizophrenia. However, information regarding NOD2 expression, localization, and function in the CNS is limited. In this work, we investigated NOD2 expression, localization, and regulation …

Keep It In Your Pants: How Sexual Regulation Becomes Identity Regulation, Madelyn Shoemaker

Dissertations

White Evangelicalism has been studied quantitatively for many years; however, this article examines in-depth interviews with ex-congregants of a specific church located in Chicago. Building from Orit Avasai’s framework of “doing religion,” I argue that due to a high saturation of isolation, sexual regulation and patriarchal power, this specific church’s script of religious performance claims master status in individual identity building, leading to adverse effects in adulthood. Much of the rhetoric utilized to justify the intense regulation of identity mirrors that of the New Right movement of the 1980’s, as well as modern political discourse. This study will assist in …

Ultramodern Racism: A Critical Discourse Analysis Of The Impact Of Anti-Crt Legislation On Us History Curriculums, Amelia Gernand

Dissertations

In the wake of Donald Trump’s failed 2020 bid for a second presidential term, there was a surge in anti-CRT legislation targeting how issues of race and racism could be taught in public school curricula. While proponents claim that anti-CRT laws will protect students of all races from discrimination, curriculums have historically been used as a tool by those with symbolic power to legitimize white supremacy and perpetuate anti-Black and color-evasive racism. Two states--Florida and Arkansas--recently enacted anti-CRT legislation in addition to Black history mandates. While legislators in these two states claim that their goal is to expand the teaching …

Computational Analysis And Characterization Of The Inducible 1-Cysteine Peroxiredoxin Promoter In The Malaria Parasite Plasmodium, Lara Ladney

Dissertations

Malaria afflicts over 200 million people annually, which results in over half a million deaths, primarily in sub-Saharan Africa. Malaria parasites are complex protozoan organisms that inhabit two hosts: humans, the site of asexual reproduction, and the Anopheles mosquito, where sexual reproduction occurs. To withstand the hostile extracellular environment of the Anopheles mosquito, the malaria parasite Plasmodium berghei employs antioxidant defense mechanisms. Previous work suggests upregulation of 1-Cysteine Peroxiredoxin (1-CPxn) when the mosquito uptakes a blood meal containing the parasite. The parasite must acclimate to the harsh environmental conditions of the mosquito midgut: find a way to counteract reactive oxygen …

The Forced Sterilization Of Quechua-Speaking Women In Peru: The Role Of Epistemic Injustice In The Perpetration Of Genocide, Geraldine Diaz

Dissertations

The forced sterilization of Quechua-speaking women in Peru from 1996 to 2000 represents a case of genocide in which the state as an epistemic agent has a fundamental role. Although the systematic sterilization was carried out under the guise of a family planning program, the targeting of these women provides strong circumstantial evidence of genocidal intent. According to the testimonies of these women, medical staff, acting on behalf of the government, performed tubal ligation procedures through coercion, threats, lies, bribery, manipulation, and other tactics where the state intentionally withheld information, misinformed women, and failed to obtain proper consent. This research …

Interactive Visualization Workflows For Mitigating Analytical Uncertainty, Kaustav Bhattacharjee

Dissertations

This dissertation takes a process-centric and stakeholder-first perspective for handling analytical uncertainty: the form of uncertainty that confronts data analysts' insight-generation processes in high-consequence decision-making scenarios. The cost of an incorrect decision when data is used for movie recommendations as opposed to when personal data is used to drive insights or when data-driven modeling is used to drive real-time decisions for maintaining the health of a grid are vastly different in terms of consequences. This dissertation looks at analytical uncertainty in two real-world scenarios: i) how sensitive information leakage can be prevented during the open data release process with data …

Crowd-Sourced Learning For Computer Graphics Applications, Yunhao Zhang

Dissertations

Computer Graphics (CG) revolves around virtual content creation using computational methods, spanning applications from games to visual effects. Typically, the creation of CG content is led by expert practitioners who guide computational algorithms towards satisfactory results. Thus, creating CG content often requires manual iterations encompassing algorithm design, parameter tuning, and aesthetic feedback. This work investigates how to leverage crowd-sourcing to streamline such creation processes, focusing on animation and simulation. In animation, a novel crowd-sourcing framework is proposed for combat animation, enabling users to analyze motion similarities, and retrieve matching motions using novel crowd-sourced motion features. Such features enable quantifying previously …

Beyond Average Effects In Education Research Syntheses: Explaining Heterogeneity Of Concept Mapping Research In Science Education Through Meta-Regression Modeling, Aaron Wenger

Dissertations

Contemporary education research seeks causal inferences in order to guide policy and practice. Often well-controlled quasi-experimental and experimental designs are used as they are very useful for supporting and contextualizing causal inferences. Nevertheless, individual studies, even high-quality, resource-intensive randomized controlled trials, are not able to establish generalized claims. Because primary studies vary over dozens of variables (e.g., grade, subject, duration) simply conducting additional primary studies cannot change this. Furthermore, the informal assessments of primary studies common in literature reviews are unable to resolve certain challenges (e.g., publication bias) that are described in the emerging field of meta-research. These challenges require …

Rethinking Safe Nurse Staffing In The Post-Covid Icu: A Comparative Analysis Of The Nurse-To-Patient Ratio And Mixed Model Approach For State Policies, Emilie A. Maxie

Dissertations

The coronavirus pandemic (COVID-19) led to an unprecedented surge in ICU admission, increasing the nurse-to-patient ratios and intensifying stress on ICU nurses. This prompted many nurses to leave bedside care, exacerbating the ongoing nursing shortage and creating unsafe working conditions. Fourteen states have enacted safe nurse staffing policies. California implemented a mandated nurse-to-patient ratio, while Massachusetts adopted a mixed model for ICUs that involves a ratio, nurse committees, and workload tools. In post-COVID, this raises the question of which state policy approach is more effective in retaining ICU nursing staff. Literature suggests a mixed policy may be more effective.

More Than Just A Grade: Factors Influencing Secondary Students’ Engagement With Digital Feedback, Mandy Prior

Dissertations

The increasing use of technology in secondary education has shifted teacher feedback practices to digital environments. While digital feedback offers many promising affordances, the factors that influence how students engage with and use digital feedback are not well understood. Previous research indicates that digital feedback poses unique challenges for engagement. New paradigm feedback models seek to identify processes and actions that promote feedback engagement. However, these models require further study in digital and pre-higher education contexts. This qualitative single-case study investigated the factors influencing secondary students' engagement with digital feedback. Data included 24 student interviews conducted across four grade levels …

The Role Of Mentorship In Teachers' Intent To Persist In P-12 Public Education, Collins Robinson

This single division focuses on enhancing specific areas: “Mentoring and Induction programs, Mississippi Professional Growth system, Mississippi Teacher Residency, and Recognition Programs.” (Steen, 2024). The purpose of the study was to determine if there exists a statistically significant relationship between Mississippi public education teachers’ mentorship experience, mentorship effectiveness, and intent to persist. Secondly, this study was expected to determine to what …

Uncovering The Causal Configurations Of Successful Nonviolent Regime Change Movements: A Systems Thinking And Fuzzy Set Analysis, William Scott Hinson

Dissertations

Under what conditions do nonviolent regime change movements succeed? While the literature on nonviolent resistance has shown several variables to be highly correlative in affecting regime change, little research to date has shown which configuration of conditions leads to regime change in differing polities and repressive environments. In this dissertation, Systems Thinking (ST) and fuzzy set Qualitative Comparative Analysis (fsQCA) are employed to analyze 25 randomly selected cases of nonviolent regime change movements drawn from the NAVCO 2.1 dataset. The principle of equifinality in ST and fsQCA directs the research to explore multiple sets of conditions that can lead to …

Artificial Intelligence, Machines, Devices, And Robots: Mobilizing Humanness And Intelligence In The American Techno-Landscape, Carlos A. Batres

Dissertations

This dissertation is an ethnographic inquiry of artificial intelligence (AI) in the techno-landscape of three major metropolitan areas in the United States. It traces the ways in which both experts and non-experts talk about their interactions with AI via machines, robots, and other devices, and how the ways in which people deal with AI-technologies have come to shape how we think about our own ways of going about doing things. The goal is to discern what the social ramifications of this technology may be as relationships and relations are formed betwixt and between people and artificially intelligent things.

Mutual Enjoyment: A Levinasian Conception Of Freedom, Aaron Darrisaw

Dissertations

Established scholars typically regard the philosophy of Emmanuel Levinas as one that offers a morally elevated, and even religious, sense to the meaning of ethics. He uses many descriptions to encapsulate his understanding of ethics, but a common shorthand is “the calling into question of freedom.” This dissertation aims to answer the following question: What becomes of freedom after it has been submitted to Levinas’s ethical critique? Engaging this question emphasizes the distinctively political significance of Levinas’s philosophy, a significance that is often regarded as lacking. However, my project treats freedom as a unique prism through which to interpret Levinas’s …

Simple Smale Flows On S3 Using Embedded Templates With Twisted Bands, Anthony Sloan

Dissertations

We study the linking structure of the attractor-repeller pairs in simple Smale flows on the 3-sphere in which the chaotic saddle set is modeled by four-band templates with twisted bands. This is a small step in an attempt to classify simple Smale flows on S³. We obtain three new theorems which illustrate that the dynamics of simple Smale flows are sensitive to half-twists in the bands of the embedded template. Haynes and Sullivan showed that the attractor-repeller pair a∪r in a simple Smale flow with chaotic saddle set modeled by embedded template U⁺ is either a Hopf link or a …

Magnetotransport Properties Of Polycrystalline Mn_(3-X)Fe_Xsn (X = 1, 2) Thin Films, Duston Wetzel

Dissertations

The incredible progress of the microelectronics industry in the last several decades hasbeen primarily due to the progressive miniaturization and optimization of the MOSFET. However, the rate of this progress is becoming unsustainable by these means. Of several proposed replacements, one of the most popular ideas is to utilize electronic spin in logical processing. The discovery of Giant Magntoresistance (GMR) in layered thin film heterostructures and the subsequent development of Tunneling Magnetoresistance (TMR) devices revolutionized magnetic field sensing, which allowed magnetic domains in hard drives to get much smaller. This enabled hard drives to get denser, but because current charge-based …

The Impact Of Restorative Practice Implementation On Culturally Responsive Teaching And Student Behavior, Patrice Mccoy

Dissertations

American public schools uphold the policies, standards, and disciplinary practices that guide the belief systems of how students view fairness and deal with conflict. As teachers invest in student knowledge and seek to guide students in the right direction, the challenge is learning the appropriate methods of dealing with student behavior. Behavior management practices have evolved just as many student challenges and needs have changed. With these changes evolves the need to better understand students and families. Teachers gaining cultural responsiveness to student behavior challenges is a relatively new ideology to ensure students feel understood and more engaged in the …

Evaluation Of Joint Model Imputation Of Multilevel Models, Gabriel Owusu

Dissertations

Missing data is a pervasive challenge in research, particularly in studies involving multilevel models. When left unaddressed or handled poorly, missing data can reduce statistical power and introduce bias, undermining the validity of findings. Although multiple imputation has emerged as a preferred method for addressing missing data due to its ability to provide unbiased and efficient estimates, its application in multilevel modeling remains underexplored. This gap is particularly significant given the hierarchical nature of multilevel data, which requires specialized approaches to imputation. The purpose of the study is to evaluate the effectiveness of joint model imputation in handling missing data …
