Factors Contributing To Teacher Attrition From The Perspectives Of Teachers Who Left The Profession, Malik Padgett

Theses and Dissertations

This applied dissertation examined teacher attrition, a persistent challenge in K–12 education. Nearly 20% of teachers leave by their third year, with up to 50% departing by the fifth year. High turnover disrupts learning, strains resources, and diminishes educational quality, particularly in under-resourced communities. Addressing these issues is crucial for improving retention and fostering stability.

The study explored key factors driving attrition, including inadequate compensation, excessive workload, insufficient professional development, and limited administrative support, especially in the post-COVID era. Grounded in transformational leadership theory, the research highlighted the role of leadership in fostering morale and ethics rather than merely transactional …

The Development Of A One Pot, Two Reaction Synthetic Preparation Of 1,2,4-Oxadiazole, And Synthesis Of Ataluren, A Novel Drug In The Fight Against Duchenne Muscular Dystrophy. Efforts Towards The Synthesis Of A Potential Protease Inhibitor Against The Main Protease (3clpro) Of Covid-19, Austin J. Carter

Theses and Dissertations

1,2,4-Oxadiazoles are five-membered heterocyclic structures first synthesized by Tiemann and Krüger in 1884. Recent discoveries suggest an array of useful biological properties.In preparation of 1,2,4-oxadiazoles, the most prevalent precursors are amidoximes, which can be created via the reaction of nitriles with hydroxylamine hydrochloride and a base. The amidoximes are reacted with an activated carboxylic acid to yield an acylated intermediate. This intermediate can be exposed to a base to cyclize into the 1,2,4-oxadiazole. This thesis describes the efforts in combining these three steps into a unified one-pot synthesis.

Currently, there are a significant number of commercially available FDA approved and …

Larval Environments Affect The Implementation Of The Sterile Insect Technique On Aedes Mosquitoes, Katherine G. Evans

Theses and Dissertations

Sterile Insect Technique (SIT) is an effective method for controlling pests and has been increasing in popularity to control Aedes mosquitoes. SIT involves inundating an area with sterilized male mosquitoes to reduce egg hatch and ultimately the number of wild adults. Previous research indicates that enacting mortality early in the larval life of Aedes mosquitoes can result in counter-productive effects, due to reduced competition among developing larvae. I hypothesize that the effectiveness of SIT at reducing adult populations is modified by densitydependent mortality and density-dependent growth among larvae. I performed two field-to-lab studies and developed an individual-based model to test …

Do Exploratory Probing Movements Predict Perceived Geometric Or Affordance Properties Of A Surface?, Arghya Kashyap

Theses and Dissertations

People use different exploratory movements to perceive different properties of a handheld object and different exploratory wielding movements to perceive different properties of a wielded object. We investigated whether people use different exploratory probing movements to perceive different properties of a surface. Participants probed a surface and attempted to perceive either an affordance (whether they could stand on that surface) or a geometric property (angle of inclination) of that surface. Perceived angle was nearly perfectly correlated with (but imperfectly scaled to) surface angle. The perceived boundary between surfaces that could be stood on and those that could not be stood …

Making Monsters: The Intersection Of Black And Queer Characters In Vampire Fiction, Jalissa Jones

Theses and Dissertations

For centuries we have looked at the vampire as a monster, one that skirts the line into acceptability not only because of the vampire's motivations, but more importantly because our depictions of vampires make them desirable to us. This thesis explores the vampire archive, and the question of how the monstrosity of the vampire interacts with race, sexuality, and gender to further uphold notions of white supremacy. This thesis will look at the classic vampire canon set forth by Bram Stoker’s Dracula and Carmilla by Sheridan Le Fanu and two contemporary black vampire narratives: The Gilda Stories by Jewelle Gomez …

Differential Effects Of Health Insurance Coverage On Health For Sexual Minorities, Ruby W. Morr

Theses and Dissertations

Much existing research has found a substantial gap in health between sexual minorities and non-minorities. This is usually attributed to discrimination or access to care. I seek to find the role that insurance plays, including minorities' choices of insurance coverage. If a gap does exist, insurance may have a stronger impact on sexual minorities. Also, if minorities are less likely to have insurance coverage, they may be susceptible to worse health. I confirm results from the literature that sexual minorities do have worse health. While health insurance accounts for some of the gap, it is only a small portion, though …

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, …

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 …
