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 …

The Effect Of Sex On The Signal Transmission Of Duetting Bay Wrens, Rachel C. Schinzler

Theses and Dissertations

During communication, senders send signals for their benefit to elicit a behavioral response from a receiver. Acoustic signals are efficient for long-distance signaling; however, they are influenced by environmental features, such as foliage density, humidity, temperature, and time of day. Individuals can overcome these challenges by using signals with a trajectory of peak frequency, frequencies, volumes, and timing best suited to signal transmission in their environment. Signal transmission has been studied at the species level; however, not much is known about sex differences within the same species. Duetting species provide a useful system for examining sex-specific challenges in transmission, as …

Schiff Bases As Versatile Platforms: From Multinuclear Dysprosium Complexes To Halogen-Mediated Quasiracemic Crystal Engineering, Macy M. Michorczyk

Theses and Dissertations

Understanding the factors that govern molecular assembly is fundamental in both coordination chemistry and crystal engineering. This thesis investigates these processes through two studies that employ single-crystal X-ray diffraction to elucidate the structural principles underlying the formation of multinuclear metal complexes and the crystal packing of quasiracemates.

The first study examines the unexpected formation of multinuclear metal complexes. Structural characterization of a series of dysprosium complexes was used to compare molecular architectures and identify structural relationships that support a proposed pathway of formation. These findings shed insight into the assembly process that may have lead to their formation.

The second …

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 …

Interaction Of The Gram-Positive Human Pathogen Staphylococcus Aureus With Host Lipids, Sharanya Paul

Theses and Dissertations

Staphylococcus aureus is a prominent pathogen that is known to incorporate straight-chain unsaturated fatty acids (SCUFAs) into its lipids in addition to the normally biosynthesized branched-chain fatty acids (BCFAs) and straight-chain fatty acids (SCFAs). Furthermore, it has recently been shown that the incorporation of oleic acid into S. aureus lipids significantly enhanced the growth of the organism at low temperatures due to the greater fluidity imparted to the membrane. Together with others in the Wilkinson and Dahl laboratory, I have shown that low-temperature growth is enhanced by various SCUFAs, including the human antimicrobial fatty acids sapienic acid, linoleic acid, and …

Children’S And Adult Perspectives On Mental Health In Children’S Youth Literature And Media, Edcel J. Cintron-Gonzalez

Theses and Dissertations

My dissertation extends existing work on mental health in children’s literature to examine the different narratives strategies that text, film, and media for young audiences use to connect childhood, caregiving, and emotional wellbeing. Three areas of scholarship—children’s literature scholarship, health humanities work, and feminist care ethics—inform my project. Overall, I am interested in how a variety of genres for young readers represent mental health not only as an individual experience, but also as something shaped by family, culture, community, and adult-child relationships. It is therefore important to delineate the different concepts and frameworks that help make sense of how mental …

Therefore, my thesis includes a discussion on Arts Integration initiatives and an illustrated book for students ages 10-15, which can be used as an example for their own studies into personal narrative. While the research presented here touches on multiple factors affecting students’ self-esteem and willingness …

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, …

Prevalence Of Grip And Leg Strength Asymmetries In U.S. Youth, Elyse M. Deschryver

Theses and Dissertations

Early-life physical activity is important for building muscular strength, supporting healthy growth and disease prevention, and for establishing physical activity and strength habits that often track into adulthood. Although grip strength asymmetry is a well-documented risk factor in older adults, evidence in children and adolescents is limited and largely based on small, sport-specific samples. PURPOSE: To describe grip and leg extension strength asymmetries in a nationally representative sample of U.S. youth aged 6–15 years using the National Youth Fitness Survey (NNYFS). METHODS: The analysis included 1,214 participants (606 boys, 608 girls) with valid grip or leg extension data. Age, sex, …

Turning 30 In 600 Feet, Tate Lewis-Carroll

Theses and Dissertations

This thesis is a poem; it records fourteen consecutive months of the poet’s life through rigorous, daily typing habits with nonoptimal tools and material: a typewriter and 600 feet of receipt paper. Through the adoption of these conditions, and through the dailiness of the habit, this thesis crips and deploys a poetics of chronic impediment for accessing constraint and its role in making. This thesis includes a critical preface which explores some of the poet’s specific relationships to chronic pain, both physical and emotional; forgetfulness and dissociation; and disruption by remembering a decade-long flare of chronic illness and abuse. With …

The Right To Read: Opposing The Censorship Of Young Adult Literature On Grounds Of Sexually Explicit Content, Kate Fortner

Theses and Dissertations

In this thesis, I use intersections between sexuality studies, feminism, queer theory, and theories of children’s and young adult literature to examine and historicize the prevalence of book bans and challenges between 2020 and 2025 that target young adult literature on the basis of sexually explicit content. To understand the opposition to portrayals of underage heterosexuality, I analyze John Green’s Looking for Alaska, considering its history of censorship as well as the author’s response to those bans. To understand the challenges to depictions of LGBTQ+ identities aimed at young people, I look at Maia Kobabe’s Gender Queer and Juno …

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 …

The Victimization Of Immigrant Adolescents, Stephanie Vargas

Theses and Dissertations

Immigrant adolescents may experience social and structural challenges that increase their vulnerability to victimization and influence long-term developmental outcomes. However, there is little longitudinal research has examined whether immigration generation is associated with adolescent victimization and adult behavioral outcomes using nationally representative data. This study used data from the National Longitudinal Study of Adolescent to Adult Health (Add Health) to examine the relationships among immigration generation, adolescent victimization, and adult criminal justice, mental health, and substance use outcomes. Logistic regression analyses were conducted to examine whether first- and second-generation immigrants differed from third-generation respondents after controlling for race/ethnicity, family structure, …

Longitudinal Associations And Interactions Of Adolescent Religious Deidentification And Parental Sanctification On Parent-Adolescent Relationships, Justin Hendricks, Sam A. Hardy, Michael A. Goodman, Emily De Schweintiz Taylor

Faculty Publications

In many religious families, shared religious identity is a strong source of intergenerational solidarity. However, when adolescents deidentify from their family faith, normative parent-adolescent conflict, which heightens in mid-adolescence and normally subsides in late-adolescence, may intensify and damage parent-adolescent social cohesion. Many religious parents view parenting relationships as sanctified, which typically leads to adaptive parenting, but in the context of deidentification may lead to greater distress. To understand how adolescent religious deidentification influences parentadolescent relationships, we examined the longitudinal associations and interactions of adolescent children’s religious deidentification and parental sanctification on parent-child religious conflict and parental warmth (N = 1,391 …

Evaluating Supplementation Strategies Using Precision Livestock Technologies And Energy Based Models In Developing Beef Heifers Grazing Dormant Rangeland, Kali-Jo Bentz

Electronic Theses and Dissertations

Replacement beef heifer development in extensive grazing systems is challenged by variation in forage quality, supplement intake, and animal behavior, all of which influence the ability to achieve targeted growth prior to breeding. Precision livestock technologies (PLT) enable continuous monitoring of individual animal performance, while energy-based nutritional models support individualized supplementation. However, their application under extensive grazing conditions remains poorly understood. Therefore, the objectives of this thesis were to (1) evaluate heifer utilization of multiple precision livestock technologies and their relationship with animal performance and (2) evaluate the accuracy of an individualized energy-based supplementation model by comparing predicted supplement allotments …

Untangling Ai Openness, Parth Nobel, Alan Z. Rozenshtein, Chinmayi Sharma

Faculty Scholarship

The debate over AI openness—whether to make components of an artificial intelligence system available for public inspection and modification—forces policymakers to balance innovation, democratized access, safety and national security. By inviting startups and researchers into the fold, it enables independent oversight and inclusive collaboration. But technology giants can also use it to entrench their own power, while adversaries can use it to shortcut years and billions of dollars in building systems, like China’s Deepseek-R1, that rival our own. How we govern AI openness today will shape the future of AI and America’s role in it.   Policymakers and scholars grasp the …

If I Only Had The Words (To Tell You): Billy Joel Lyrics In Legal And Medical Scholarship, Seuli Bose Brill, Christian H. Brill

Touro Law Review

Law and medicine are often considered to be among the least accessible professions, partly because of the heavy use of non colloquial jargon. This article examines more than 150 instances in which Billy Joel’s lyrics have been used to improve the accessibility of legal and medical scholarship. Legal and medical professionals have used the words of the “Piano Man” to discuss a variety of topics—everything from civil procedure to property rights and the COVID-19 pandemic to colorectal surgery. Nontraditional communications techniques of this type do not just contribute to the body of legal and medical scholarship; they also help professionals …

Plant-Insect Interactions In Great Plains Restoration And Invasion Ecology, Joseph H. Cammarano

Electronic Theses and Dissertations

Prairie ecosystem loss and invasive plant species are major ecological problems in the Great Plains. Plant-insect interactions have important consequences for both the restoration of prairie ecosystems and management of invasive plant species. Pollinating insects are vital to the sustainability of prairie ecosystems, and herbivorous insects can provide biological control of invasive plant species. Understanding how restoration strategies may influence potential pollinator communities can have important consequences for restoration sustainability and success and understanding how biological control strategies may help manage invasive plant populations can also help land managers reach restoration and conservation goals. In Ch. 2, I sought to …

Enzyme Susceptibility And Functionality Of High Protein Retentates And Reconstituted Ingredients, Khushi Dubey

Electronic Theses and Dissertations

This thesis explores the effects of processing history on the enzymatic susceptibility and functional properties of high-protein dairy ingredients, with a specific focus on ultrafiltered (UF) and microfiltered (MF) retentates and spray-dried powders. While retentates and powders are often used interchangeably in industrial applications, processing steps, such as drying, can induce structural and physicochemical changes that affect protein functionality and enzyme accessibility. Milk protein concentrates (MPC) and micellar casein concentrates (MCC) were standardized to 10% protein and subjected to enzymatic treatments, including proteolysis (Alcalase and rennet) and crosslinking (transglutaminase and laccase). Structural modifications were evaluated using capillary gel electrophoresis, non-protein …
