Stimulating Focus And Calmness Through Soft Fabrication: A User-Centered Approach, Emmanuella A. Oku

Theses and Dissertations

This study explores the potential of active attention objects embedded with technologies such as LEDs to enhance focus and calmness in individuals with inattentive ADHD, particularly in classroom settings. Individuals with inattentive ADHD often struggle with irritability, stress, and panic attacks when exposed to external stimuli such as loud sounds, varying light intensities, strong smells, or physical sensations, which significantly hinders their ability to concentrate and remain composed. My literature review discovered a connection between an individual’s blinking pattern and their focus, and my work explores how to design active attention objects to engage with blinking as a focus tactic. …

On Higher Level Zhu Algebras Of N-Graded Vertex Algebras Associated With Simple Leibniz Algebras That Contain Sl2, Christian Soltermann

Theses and Dissertations

In this thesis, we study how the higher-level Zhu algebras of a vertex algebra reflect the structure of associated simple Leibniz algebras. In particular, we construct a vertex algebra from a vertex algebroid containing the simple Lie algebra sl₂ and analyze its higher level Zhu algebras. The irreducible modules of this vertex algebra were completely classified in [JY20b], but the structure of its indecomposable modules remains an open problem. Since modules for higher level Zhu algebras correspond to modules of vertex algebras, studying these algebras provides a method for understanding their broader representation theory.

The Impact Of Loss Function Topology On Gradient Descent, Robert B. Skudnig Jr.

Theses and Dissertations

Gradient descent is a popular optimization method that utilizes a model’s prediction error to iteratively improve its parameters for a given task. The functions that measure this error can be defined to align with the user’s goals and sometimes satisfy metric or norm properties. It is common for these functions to measure over Rn, but any differentiable space allows for gradient descent to occur. There has been some research investigating the influence of topological spaces on optimization methods, but it is a limited field of study. This thesis further explores this phenomenon by applying a transformation prediction model to multiple …

Marks Of Heritage: Chicana Tattoo Artists Navigating Gender, Culture, And Artistic Expression In "Men's Work", Ryleigh Hickman

Theses and Dissertations

Art, and tattoos especially, have been fundamental in creating and articulating an identity for Chicanos within the United States. Yet, for much of the history of Chicano style tattoos, Chicana/xs were not free to engage with them in the same way that Chicanos were. In many regards, their entrance into these spaces was restricted (Santos 2009). However, recently with the growing interest in tattoo art and career opportunities, the industry has expanded significantly, creating more opportunities for a broader range of individuals. This research aims to explore how young Chicana/x and Latina tattoo artists now accessing these spaces navigate and …

The Future Of Democracy Is At Risk As Declining Local Media Erodes Voter Turnout, Melissa Boehning Libert

Theses and Dissertations

The loss of local news sources has social and political consequences. The effects of media decline have been studied extensively at the national level and less so at the state level. However, this is only the second attempt to examine the effects of local media decline. This thesis argues that local media is in crisis, and its decline is correlated with another crisis: diminishing municipal voter turnout. This research examines losses in local newspapers in 45 Illinois counties and how that decline has affected voter turnout in municipal elections held from 2005 to 2023. Regression results suggest that voter turnout …

A Phenomenological Look At Mental Blocks In Artistic Gymnastics, Lauren M. Rogers

Theses and Dissertations

Mental blocks are a poorly understood but pervasive and challenging phenomenon in artistic gymnastics that are characterized by a disconnect between the mind and body and an interference with athletes’ ability to physically perform previously automatic skills. This study used interpretive phenomenological analysis to explore the lived experiences of female D-I collegiate gymnasts in the United States who have struggled with mental blocks, examining the characteristics, causes, and management strategies through semi-structured interviews. Findings suggest that mental blocks are best understood on a spectrum and are difficult to attribute to a single cause as they often stem from a combination …

I Am Not A Dictator; I Am A Defender: The Rhetoric Of Coup D’État In Francophone Africa, Isaac Asare Kwakye

Theses and Dissertations

This study examines the rhetorical strategies used by coup leaders in Francophone Africa to authorize their actions and garner public support. Focusing on recent military takeovers in Mali, Burkina Faso, and Niger since 2020, I investigate how coup leaders construct narratives of legitimacy within the context of contemporary geopolitical dynamics. I utilize Critical Discourse Analysis (CDA) to analyze speeches by three key coup leaders: Colonel Assimi Goïta, Captain Ibrahim Traoré, and General Abdourahamane Tchiani. My analysis reveals four interconnected rhetorical frameworks: framing interventions as emergency measures, cultivating savior personas, weaponizing anti-colonial grievances, and deploying anti-corruption narratives. A comparative analysis of …

Nutrient Transport And Transformation In Anaerobic Co-Digestion Of Crop Residues And Swine Manure, Shelby Stoner

Theses and Dissertations

Cover crops may improve soil quality, water quality, soil health, reduce soil fertilizer use, and increase nutrient availability to cash crops. The benefits of cover crops are discussed due to the below ground presence of cover crops, but the aboveground biomass can serve as a source of sustainable energy through anerobic digestion. The nutrients in the above ground biomass can also be recycled and reused through land application of digestion effluent. We have tested anaerobic co-digestion of different biomass feedstocks: cover crops, soybean stalk, and corn stover with swine manure using both small and pilot scale digesters. Nutrients, specifically NPK, …

Findings revealed three primary strategies: framing AI as a tool that enhances rather than replaces human capabilities, connecting AI initiatives to organizational purpose and business goals, and demonstrating practical use cases through concrete examples. The study also highlighted the importance of establishing clear guidelines for responsible AI use, making initial adoption optional rather than mandatory, and directly addressing job security concerns. …

Perceptions Of A Hypothetical Student As A Function Of Binge Eating Disorder And Gender, Erin Rose Hennessy

Theses and Dissertations

Stigma toward those with binge eating disorder and a gender bias toward eating disorders can lead to misattribution of symptoms as well as a reduced likelihood of having the diagnosis of eating disorders (Currin, Schmidt, and Waller 2007). Symptoms of binge eating, such as being overweight, have different social meanings than an eating disorder that can lead to being underweight, such as anorexia (Saguy and Gruys 2010). In addition, social support has been previously found to have positive relationships with eating disorder recovery. The purpose of this study was to understand differences in people’s perceptions of targets who are overweight …

“My Pain Was Never More Valuable Than His Potential”: A Rhetorical Thematic Analysis Of Gaslighting Within Sexual Abuse Cases, Makayla Roller

Theses and Dissertations

This thesis examines gaslighting within three prominent sexual abuse cases—Harvey Weinstein, Matt Lauer, and Larry Nassar—uncovered during the #MeToo movement, to better understand the rhetorical function of gaslighting. Using a combination of rhetorical thematic analysis, critical discourse analysis, a feminist lens, and a gaslighting schema, this study identifies the rhetorical tactics, gendered discourse, and power-laden discourse deployed to gaslight victims and the public. I argue that gaslighting must be examined through a rhetorical lens, as discourse is the mechanism through which gaslighting operates, shaping perceptions of truth, credibility, and power. By highlighting how language is weaponized to deny, distort, and …

The Tender Flesh: Dwelling In Soft Wounds And Visceral Bodies, Madelyn Irene Turner-Havens

Theses and Dissertations

Within my painting process, I explore bodily interiority and exteriority in relation to the surface of painting, evoking a discomforting sense of corporeal (dis)embodiment, where haunted flesh becomes palpable. Indexing conversations with the body into the painting is a way to understand my body and create an experience of what happens when language fails to capture the complexity of sensation. Painting becomes a mediation with the canvas, a constant discovery of what can give shape to the intangible: how it feels when my skin folds into itself, bodily urges, and the soft texture of fatty tissue.

I let the parts …

Perceptions And Treatment Decisions For A Drug Offender Based On Social Class, Cocaine Type, Personal Characteristics, And Compassionate Love: A Vignette Study, Yasmin A. Odeh

Theses and Dissertations

Problem: The shift from a focus on rehabilitation to the more punitive, “tough on crime” approach to illegal behavior in the U.S. has been enacted in no small way by policies connected to the use and abuse of drugs. The disparities between crack and powder cocaine—two chemically similar substances—have headlined this shift (Vagins and McCurdy 2006). However, research is scarce on laypeople’s approval of deterrence approaches for drug offenses, including as a function of types (e.g., powder vs. cocaine possession). This study examined people’s perceptions of prosecutorial decisions for drug offenders—whether they are punished, rehabilitated, or both—and whether people perceived …

Normalizing Delinquency And Risky Behaviors In Adolescents: An Application Of Neutralization Theory To Parents, Audrey Cheatham

Theses and Dissertations

Sykes and Matza’s Neutralization theory (1957) was originally developed to explain juvenile involvement in delinquency, with extensions of this theory being used to understand crime in other offending groups. Although neutralization theory has been widely applied to offenders, far less research has examined how neutralizations may be used by non-offending groups. This study applies Sykes and Matza’s framework to parents to explore whether neutralizations are being employed to justify risk taking or delinquent behavior among their adolescent children. This study also examines how parents differentiate risky behavior from delinquent behavior, as well as their attitude towards seven major risk factors …
