A Narrative Analysis Of The January 6th Capitol Riot: Melodramatic Political Discourse, Joel Corte

Theses and Dissertations

The riot at the United States Capitol by supporters of Donald Trump shocked the American political system and represented contemporary politics’ shift toward more reactionary, populist politics. Attempts to explain the events of January 6th, 2021, have focused on the role of conspiracy theories, white supremacy, toxic masculinity, and the violation of norms. This thesis argues that January 6th can be explained by a case study of narrative and the style of discourse. More specifically, I conducted a qualitative narrative analysis of Trump’s election fraud narrative in the 2020 election by completing a close reading of his campaign …

Examining Factors Among People With Opioid Use Disorder And Comorbid Mental Health Disorders, Tori Denae Livingston

Theses and Dissertations

Opioid use disorder (OUD) affects over two million Americans, and over 42,000 Americans perished of opioid overdoses in 2016 (Volkow et al., 2019). During the initial years of the opioid crisis, overdose deaths were primarily attributed to prescription analgesics, heroin, and synthetic opioids. However, it was illicit prescription opioid painkiller use that ranked highest in terms of fatalities (Volkow et al., 2019). The increasing prevalence of opioid use among individuals with mental health disorders is in stark contrast to the ongoing opioid crisis (Prince, 2019). Additionally, there is evidence that individuals undergoing substance use treatment and concurrently suffering from a …

A Hybrid Cognitive Model For Machine Agents In Project And Action Teams, Joshua A. Lapso

Theses and Dissertations

High performing human teams transcend complex domain uncertainty by achieving an emergent state of shared cognition, in which knowledge is organized, represented, and distributed to team members for rapid execution. However, this requires that individuals emit perceivable qualities upon which other members can make inferences about intent. In pursuit of future human and machine team studies, this research presents a hybrid cognitive model for machine agents in fully cooperative and semi-cooperative action and project teams. The hybrid cognitive model unifies the characteristics of the shared mental model and transactive memory system. The resultant model facilitates anytime selection over the two …

Federated Active Learning For Network Intrusion Detection, Matthew D. R. Sauer

Theses and Dissertations

This thesis addresses challenges with detecting attacks on computer networks within a Federated Learning (FL) framework, when labeled instances are few. We explore the integration of active learning (AL) and semi-supervised learning (SSL). AL efficiently uses data that would otherwise be wasted or require substantial time for labeling. SSL provides capacity to train models that have a limited amount of labeled data, by utilizing additional unlabeled data that is available. We show how FL combined with AL or SSL can realize a detection system that adapts and trains quickly to new networks, reducing the total amount of data labeling needed. …

Hyperplane Arrangements Over The Ring Of Integers Modulo N., Ehiareshan James Obeahon

Theses and Dissertations

Let V be a finite vector space of dimension n over the field K. A hyperplane in V is an n − 1 dimensional subspace of V defined by an equation of the form∑ni=1 aixi = 0, ai ∈ K, (x1, ..., xn) ∈ V . A hyperplane arrangement is any finite collectionof hyperplanes. This work focuses on some hyperplanes arrangements such as the braid and the graphical arrangement {xi − xj = 0 : 1 ≤ i < j ≤ n}, the shi arrangement {xi − xj = 1 : 1 ≤ i < j ≤ n}, the threshold arrangement {xi + xj = 0 : 1 ≤ i < j ≤ n}, and the complete arrangement {∑i∈S xi = 0 : S ⊆ [n]}. The graphical arrangement is a subarrangement of the threshold arrangement. Chapter 1 gives an introductory overview of the entire work, the significance of hyperplane arrangements, and their interconnections.Chapter 2 presents some of the important definitions and the general theory underlying hyperplane arrangements. Chapter 2 also introduces what we would call the most important concept in the study of hyperplane arrangement, which is the characteristic polynomial. Every hyperplane arrangement(or simply arrangement) can be identified by a unique characteristic polynomial. Chapter 3 covers the braid, graphical, and Shi arrangement, and application to graph coloring, while Chapter 4 explores the threshold arrangement, and how it relates to threshold graphs. There is a bijection between the set of threshold graphs on n vertices and the set of regions of the boxed threshold arrangement. Finally, chapter 5 gives an introduction to the complete arrangement.

KEYWORDS: Threshold Arrangement, Characteristic Polynomial, Finite Field Method.

Stability, Longevity, And Regulatory Bionetworks, Christian N. K. Anderson

Theses and Dissertations

Genome-wide studies of diseases and chronic conditions frequently fail to uncover marked or consistent differences in RNA or protein concentrations. However, the developing field of kinetic proteomics has made promising discoveries in differences in the turnover rate of these same proteins, even when concentrations were not necessarily different. The situation can theoretically be modeled mathematically using bifurcation equations, but uncovering the proper form of these is difficult. To this end, we developed TWIG, a method for characterizing bifurcations that leverages information geometry to identify drivers of complex systems. Using this, we characterized the bifurcation and stability properties of all 132 …

Seeking Connection By Forsaking Self: Associations Of Autonomy And Relatedness With Self-Silencing And Emotional Fusion, Amber A. Price

Theses and Dissertations

Humans innately feel a desire for connection, but in its pursuit, some may inadvertently thwart the very connection they seek. One way this may happen is through forsaking a sense of autonomy in favor of relatedness using behaviors such as self- silencing (stifling the self to preserve a relationship) and emotional fusion (relying on validation from others). To better understand how these four variables—autonomy, relatedness, self-silencing and emotional fusion—function together, I used latent profile analysis to identify classes among US adults in long-term relationships (n = 1065). Separate classes were identified for men and women. I then used the Bolck-Croon-Hagenaars …
