This qualitative investigation employed case study methodology. The case study focused on one school within a charter management organization (CMO), exploring interactions among Black teachers and their supervising administrators at the site and management organization levels. The study was organized around concepts articulated at the nexus of teacher retention scholarship and human resource management theory, two bodies of literature yet to be substantially integrated to understand Black teachers’ …

Computational Study Of Nonlinear Electrokinetic Phenomena In Shear-Thinning Fluids, Wai Yuen Leung

All Theses

Electrokinetic phenomena have been widely used for fluid pumping and particle manipulation in micro/nanofluidic systems. They refer to the motion of fluids or particles in response to an electric field because of the spontaneous formation of an electric double layer at the fluid-solid interface. Understanding electrokinetic phenomena in micro/nanochannels is critical for a wide range of applications across various engineering fields, such as disease diagnostics, contaminant treatment and cell analysis. To date, numerous studies have been reported on electrokinetic phenomena in Newtonian fluids, where the classical Helmholtz-Smoluchowski theory indicates a linear relationship between fluid electroosmosis/particle electrophoresis and electric field.

3,5-Dihydroxy-4-Isopropylstilbene (Tapinarof) Is A Partial Aryl Hydrocarbon Receptor Agonist In Fish, Conner A. Dicks

All Theses

The aryl hydrocarbon receptor (AHR) is a ligand activated transcription factor that is essential in regulating development, immune homeostasis, and drug and xenobiotic metabolism. Activation of the AHR by specific ligands results in its translocation to the nucleus where it induces a myriad of gene products, including cytochrome P450 (CYP) drug metabolizing enzymes (e.g., CYP1A1) and other components of the chemical defensome, as well as inflammatory control. Interestingly, the AHR can bind a wide variety of endogenous and xenobiotic ligands which are able to induce unique downstream effects dependent on cell type, inflammatory context, and ligand stability. The AHR is …

On The Garoufalidis-Kashaev State-Integral Invariant, Amelia Palmer Dusenbury

Boise State University Theses and Dissertations

This thesis explores a construction of the family of topological invariants for certain oriented 3-manifolds based on the state-integral approach developed by Andersen, Garoufalidis, and Kashaev in the Archimedean setting. Starting from an ideal triangulation of a 3-manifold equipped with angle data, variables are assigned to the faces and tetrahedra, taking values in a so-called 'Gaussian group'. The invariant is defined by integrating a distribution defined from the combinatorics of the triangulation and a special function over a product of the Gaussian group. The special function is a quantum dilogarithm, whose valuable feature, the pentagon relation, ensures the resulting integral …

Cg18562578 Methylquant Assay For The Discrimination Of Monozygotic Twins, Amber P. Chauca

Student Theses

Monozygotic (MZ) twins have identical DNA, making traditional profiling methods insufficient in their discrimination. However, MZ twins can be differentiated by their levels of DNA methylation. Our research group previously developed a methodology to detect cg18562578 DNA methylation levels in MZ twins based on a two- step PCR approach and a cg18562578 MethylQuant Assay. That study generated data for only 64% of the samples it investigated, and showed a discrimination power of 77% to discriminate between MZ twins. Here, we used the same methodology but a different approach to determine DNA methylation in 73 previously unsuccessful twin pairs. We diluted …

Bystanders Intervening During Acts Of Cyberbullying: Examining The Moderating Influence Of “Likes” And Pleas For Help, Joseph Kallman

Student Theses

Abstract

Cyberbullying research has only recently begun exploring “cyberstanders,” also known as bystanders, and their role in cyberbullying, as well as testing the bystander effect (Barlinska et al., 2013; Machackova et al., 2013; Obermaier et al., 2016; Shultz et al., 2014). In the current study, we aim to deepen our understanding of the bystander effect by manipulating the number of likes, which will indicate the number of bystanders present and the plea for help on social media via Twitter among college students, by examining how participants respond to fictitious cyberbullying incidents. The results of this study did not support our …

The yeast Candida albicans is a facultative anaerobe residing in the human digestive tract. Although fungal genetic determinants of mammalian host colonization have been identified, little is known about signals and molecules in the intestinal environment that influence C. albicans proliferation. Previously unpublished data from the Perez lab showed that oleic acid, one of the most abundant long-chain fatty acids in nature, promotes C. albicans colonization of the murine intestine. The goal of this research is to …

Drug Delivery, Disulfide Crosslinked Hydrogel Coating For Polydimethylsiloxane (Pdms) Implant Materials, Paul A. Contos, Paul Anthony Contos

Master's Theses

Though polydimethylsiloxane (PDMS) is often used in medical devices due to its desirable mechanical properties and biocompatibility, its surface is often prone to bacterial adhesion. This is especially a problem for catheters, where bacteria can adhere and form biofilms that can in turn result in Urinary Tract Infections (UTI). In order to deter the presence of UTI causing bacteria on PDMS catheters, methods were developed to formulate a disulfide crosslinked hydrogel coating and create a methodology to allow adhesion to a PDMS substrate. The hydrogel coating discussed in this paper will be synthesized by chemically crosslinking stimuli-responsive vesicles, that carry …

Designing Multilingual (Maker) Spaces: Exploring The Intersections Of Play, Posthumanism, And Pre-Kindergarten, Victoria G. Pennington

All Dissertations

In this dissertation, I explore the posthuman play literacies of multilingual makerspaces with four-year-olds, emphasizing the need for such a study while situating my arguments within the existing literature and outlining my methodological approach. Chapter One critiques the public 4-year-old kindergarten systems, arguing institutionalized cultural and linguistic ideologies restrict multilingual learners’ (MLs) opportunities for meaning-making. I draw on the raciolinguistic perspective (Flores & Rosa, 2015) and its intersection with a posthumanist paradigm (Braidotti, 2013), framing my research questions as lines of inquiry to guide the study. Key posthumanist literacies concepts are defined, highlighting the entanglement of literacies, discourses, materials, and …

Using a qualitative multiple-case study design, data were collected from three teachers participating in a professional learning group called MORE …

Organizational Metamorphosis: When Artificial Intelligence Transforms Companies Into New Economic Life Forms, Allan M. Glass

All Dissertations

Traditional theories of organizational change fall short in explaining how artificial intelligence (AI) transforms organizations. This grounded theory study, based on interviews with 34 organizational leaders, identifies a novel phenomenon: organizational metamorphosis - the irreversible transformation of organizations into fundamentally new entities through deep integration with AI as a cognitive partner.

The metamorphosis process unfolds in three phases. Individual Awakening occurs when leaders experience powerful interactions with AI, prompting a rapid shift from skepticism to advocacy. Once a critical mass of leaders undergo this shift, it initiates Organizational Restructuring, characterized by reimagined work design, boundary dissolution, and altered temporal rhythms. …

Exploring Teacher Decision-Making Based On 4k Children’S Emotional Observations And Narratives: A Multiple Case Study, Keith Johnston

All Dissertations

The benefits of quality social-emotional instruction in early childhood programs are well established. The crux of delivering these benefits lies in teacher social-emotional decision-making in early childhood classrooms. While there is scant research on the topic, there is evidence that decentralizing social-emotional decision-making can help teachers achieve better outcomes by including families and other early childhood professionals, using data to inform decisions, and reviewing research. The current study is a multi-case qualitative analysis of two 4K teachers from a child development center in the South Carolina Upstate. It describes how the two subjects use social-emotional decision-making to support their students’ …

Emotional Safety In Pediatrics: The Impact Of Child Life Services On Healthcare Professionals’ Perceptions Of Their Own, Patients’, And Families’ Outpatient Experiences, Jenni Davis

All Dissertations

Medical visits, regardless of setting, are stressful for children and their families. Care that focuses on the emotional safety of children and families can help reduce this stress. However, not all staff feel prepared to provide emotionally safe care. Child life specialists (CLSs) are specifically trained to support emotional needs during healthcare encounters. Their presence may help staff stress as well, not just stress for children and families.

This study used three surveys to understand stress among healthcare staff working in pediatric outpatient clinics and surgery settings, and how support from a CLS affects staff, children, and families. All staff …

Exploring The Socio-Cultural Dynamics Of Nocturnal Urban Landscapes: A Case Study, Jie Kong

All Dissertations

This dissertation explores nighttime social leisure activities in public parks within urban working- and middle-class communities. As cities confront climate change, shifting work schedules, and post-pandemic lifestyles, neighborhood parks have gained renewed importance after dark, especially in areas where households have limited private space. These non-commercial nighttime uses are often overlooked in planning, design, and built environment studies, yet they play a vital role in fostering cultural identity, social connection, and community well-being.

Focusing on Williamsburg and Bushwick in Brooklyn, New York, this research investigates how public parks are used at night, by whom, and for what purposes. New York …

Nature Playscape: Investigating Children’S Play Behavior And Environmental Affordances In A School Playground, Sara E. Billie

All Dissertations

Existing research demonstrates that the physical environment can either hinder or enhance children’s play behavior. Diverse outdoor settings are especially effective in fostering motivation to play, contributing to children’s physical, social, and cognitive development. In response to the growing belief that outdoor play is both a necessity and a right for young children, particularly amidst concerns about nature deficit disorder and the rise of urban living among children, this study investigates the concept of nature playscapes, or naturalized playgrounds, as a vehicle for reconnecting children with the natural world. While contemporary playground design often struggles to balance structure with creativity, …

Flipping The Script?: The Development And Validation Of A Qualitative Framework For Identifying Key Cognitive And Attitudinal Components Of Conflict-Based Problem Representations, Kyle Christenson

All Dissertations

When people work together, disagreements are inevitable. How someone understands a given conflict, specifically whether they see it as a shared problem or not, can shape how they respond and whether they look to resolve it collaboratively. Researchers have studied many aspects of conflict, like what causes it and the strategies people use to manage it. But we know much less about how people think about conflict in the first place and how those thoughts affect efforts to manage conflict. This research developed a tool to study how people describe conflicts in writing. It identifies key ideas and attitudes that …

Ecomorphological Diversification Of Tooth Complexity In The Oral Jaws Of Marine Teleostean Fishes, Keiffer L. Williams

All Dissertations

Teeth are essential biological tools that function as a direct interface between predator and prey, thus providing essential insights into the evolutionary history and ecological diversity of vertebrates. Historically, studies on vertebrate dentitions have been qualitative and focused on mammals. More recently, quantitative methods have been developed that can reliably measure tooth surface complexity. These methods have been applied across both mammals and saurian reptiles to test for correlations with diet, leading to the conclusion that herbivorous species generally possess higher overall tooth complexity than any other dietary group. Surprisingly, the relationship between tooth complexity and diet in the most …

Interactions Of Biorational And Synthetic Dmi Fungicides For Control Of Fruit Diseases, Johanna Wesche

All Dissertations

Biological fungicides are increasingly investigated as sustainable alternatives to synthetic fungicides in fruit crop protection. This dissertation examines the interactions between two commercial biological fungicides, Bacillus subtilis AFS032321 (Theia) and metabolites of Pseudomonas chlororaphis AFS009 (Howler EVO); and demethylation inhibitor (DMI) fungicides, with a focus on compatibility, synergistic potential, and resistance implications. In vitro assays revealed that commonly used DMI fungicides difenoconazole, metconazole, tebuconazole, and propiconazole inhibited vegetative growth of B. subtilis at concentrations above 50 µg/ml, whereas mefentrifluconazole promoted colony expansion. Under controlled conditions, lesion development on detached fruit was inhibited synergistically when Theia was combined with the growth-promoting …

Improved Rumen Microbiome Interpretation Via Empirical Filtration Derived From Known Mock Microbiomes, Wesley A. Tom

School of Biological Sciences: Dissertations, Theses, and Student Research

The rumen microbiome plays a critical role in ruminant health and performance. As a consequence, many studies investigate microbial community composition using 16S rDNA based sequencing. As such, data quality and data filtering are critical to accurately identify microbial community composition. In this study we use mock communities to empirically select data filtering parameters to reduce artifact populations and compared the effect of filtering using different bioinformatic pipelines using rumen bacterial community data. The filtering parameters identified provides consistent estimates of rumen microbial diversity, regardless of bioinformatic pipeline utilized and provides a more accurate view of microbiome structure and composition. …

Jury Decision Rules In Criminal Trials, Emma Archibald

Dalhousie Journal of Legal Studies

Discussions of juries in democratic systems often frame the jury as a symbol of democracy, an essential safeguard for an accused, and a legitimizer of state authority. However, the context in which the jury operates has evolved, and there is a widening gap between our empirical understanding of juries and our commitment to their theoretical value. Piecemeal reforms of the jury have also moved the system away from the historical model, with the consequence of undermining the remaining aspects. This paper argues one such aspect is the decision rule under which a jury renders its verdict. Canada is one of …
