Reconceptualizing Instructional Supervision For Stem Education In The Digital Age, Armen Alvarez

Theses and Dissertations

This conceptual thesis reconceptualizes instructional supervision for AI-enabled STEM teaching in the Digital Age. Traditional supervision models, including clinical, developmental, and cognitive coaching, emphasize human-centered observation and feedback but lack guidance for supervising AI-mediated instruction, interpreting algorithmic outputs, and addressing neurodiverse learner variability. Using integrative literature review methodology, this thesis synthesizes scholarship across five theoretical foundations: epistemic perspectives, the neurodiversity paradigm, Universal Design for Learning, human-centered AI and educational leadership, and supervision literature.

The resulting conceptual framework organizes supervisory attention into four interconnected domains:

• human-centered AI use in teaching and assessment,
• neurodiversity- and UDL-informed pedagogy,
• relational and compassionate classroom climate, …

Create Your Character: Application Of Identity Play Findings From Cosplay And Video Games Onto Tabletop Roleplaying Games, Farhia A. Osman

Theses and Dissertations

Tabletop roleplaying games (TTRPGs) are collaborative, imaginative games in which players create and enact fictional characters within shared narrative worlds. Although research on roleplaying games has expanded in recent years, much of the empirical literature has focused on digital roleplaying games, particularly massively multiplayer online roleplaying games, leaving tabletop roleplaying comparatively understudied. I conducted a study with 173 adult TTRPG players to examine the relations among openness to experience, motivations for playing TTRPGs, and avatar identification. I also explored whether the individual facets to openness to experience predicted motivations for play and avatar identification, and whether players who had portrayed …

Modeling The Impact Of Projected Water Demand On Groundwater Flow And Transport In The Mahomet Aquifer, Christabel Chinonye Abugu

Theses and Dissertations

The Mahomet Aquifer is a vital groundwater resource in east-central Illinois, supporting municipal, agricultural, and industrial water use. With projected changes in water demand driven by population growth and future socioeconomic conditions, assessing the long-term response of the aquifer is critical for sustainable groundwater management. Increased pumping to meet future demand may contribute to groundwater-level decline, intensified cones of depression, and altered groundwater-flow paths relevant to contaminant migration. This study addressed two research questions: (1) how projected changes in groundwater demand affect groundwater levels in the Mahomet Aquifer, and (2) how projected demand influences groundwater-flow paths relevant to contaminant migration. …

These results relate to theories of service quality, emotional labor, and organization-public relationships by illustrating how crisis …

The Synergy Between A Silver-Ruthenium Antimicrobial And Aminoglycosides Is Based On Severe Macromolecular Damage, Emmanuel Parkay Oladokun

Theses and Dissertations

The rise of multidrug-resistant (MDR) bacterial pathogens, including uropathogenic Escherichia coli (UPEC), highlights the urgent need for alternative treatment strategies to restore antibiotic efficacy. The silver-ruthenium antimicrobial AGXX exerts potent bactericidal effects through the production of reactive oxygen species (ROS); however, its potential synergy with antibiotics has not been thoroughly investigated. Here, we show that sublethal concentrations of AGXX strongly enhance aminoglycoside-mediated killing across a diverse panel of Gram-negative and Gram-positive MDR clinical isolates, including highly aminoglycoside-resistant strains. Combinational treatments significantly reduced the effective concentrations of gentamicin, tobramycin, kanamycin, and amikacin required to kill bacteria. Mechanistic analyses revealed that AGXX/aminoglycoside …

Promoting Emotion Regulation: A Group Based Program For Children With Autism Spectrum Disorder And Their Caregivers, Emily Jasinski

Theses and Dissertations

Emotion regulation skills lay the foundation for effective social interactions and future success. Children on the autism spectrum experience greater difficulties regulating their emotions than their neurotypical peers, leading to difficulties in social and academic settings. Therefore, it is essential to directly teach these children emotion regulation strategies. Additionally, autistic children often have difficulties generalizing what they have learned from one setting to another, and as such it has been helpful to involve caregivers in their treatment. Currently, the scant research that exists primarily describes emotion regulation interventions implemented in individual settings, which are both time intensive and expensive. One …

Exploring The Role Of Racial Microaggressions And Campus Climate In Fostering Sense Of Belonging For Black Latiné College Students, Lourdes D. Concepción Cabán

Theses and Dissertations

Racial microaggressions are subtle verbal or nonverbal behaviors that convey hostility and exclusion toward People of Color (Sue et al., 2007). These acts negatively impact the well-being, perceptions of inclusivity, and sense of belonging of marginalized groups in higher education (Solórzano & Pérez Huber, 2020). Black Latiné college students face unique challenges at the intersection of anti-Blackness and racialized Latinidad, compounding the effects of racial microaggressions in historically white institutions (Torres et al., 2012). I conducted a study with 77 Black Latiné undergraduate students from Midwestern universities to examine the relation between racial microaggressions, perceptions of campus climate, and sense …

Interactive Effects Of Bti Larviciding And Predation On Culex Pipiens And Its Ephemeral Pond Communities, Jaclyn S. Everly

Theses and Dissertations

Populations of adult vector mosquitoes can be controlled by reducing larval mosquito abundances in aquatic habitats. This can be achieved via predation by introduced or naturally-occurring enemies (i.e., biocontrol or conservation control) or by applying pesticides to larval mosquito habitats (i.e., larviciding). The larvicide Bacillus thuringiensis israelensis (Bti) is commonly applied to ephemeral ponds to control populations of Culex pipiens mosquitoes that vector West Nile virus. However, there is concern that Bti may directly or indirectly harm non-target organisms such as dragonfly and damselfly naiads, which provide a natural source of mosquito biocontrol. Bti or predators may also induce positive …
