Predictors Of General Education Teachers' Self-Efficacy For Educating Autistic Students: Enactive Mastery Experiences, Vicarious Experiences, Verbal/Social Persuasions, And Physiological And Affective States, Renette Portecop-Prentice

Dissertations

Problem

Autism is a complex neurodevelopmental condition that presents challenges not only for autistic individuals, but also for their families, healthcare providers and school professionals. A significant number of children with autism spend most of their school day in general education classrooms with teachers who may lack autism-specific training and are unfamiliar with evidence-based practices for supporting autistic students. This lack of training or relevant resources specific to autism may impact teacher self-efficacy for educating autistic students, which in turn may affect instructional decisions and student outcomes. Guided by Bandura’s theoretical framework, this study examined the relationships among autism-specific training …

Mansiones: A New Look At Mansio Archaeology In Light Of San Miceli And Household Archaeology, Christopher Randall Chadwick

Dissertations

Problem

The identification of mansiones in the archaeological record has proven difficult, if not impossible. One factor contributing to the problem has been focusing on typological and descriptive studies in order to identify the functional characteristics of mansiones. Another has been the lack of any explicit method and theory for interpreting the functional characteristics of the archaeological data related to mansiones. Both of these factors have been observed in the recent excavations at San Miceli.

Method

Due to the functional nature of mansiones, there is a need to reevaluate current paradigms for interpreting the archaeological data related to mansiones. One …

Shattering The Glass Ceiling, Navigating The Glass Cliffs: A Case Study Of Andrea Luxton As The First Woman President Of Andrews University (2016-2023), Maureen Sakshi Pakalahati

Dissertations

Problems

Research shows glass ceilings are thicker in faith-based institutions heavily governed by traditional beliefs and dominated by men. Research also shows singlism is on the rise in churches. There is limited research on the lived experiences of single, never married woman who reached the presidency (shattering the glass ceiling) in a faith-based institution. Leadership pundits predict a “great resignation”, which is an era of high presidential turnover, due to mounting challenges in the higher education presidency. Great resignation is a gender-neutral phenomenon, but women presidents are subject to stern criticism and penalties, leading to more disproportionate resignations. Furthermore, the …

Characterizing Niche Specialization In Staphylococcus Epidermidis, Sandra Jablonsk

Dissertations

This thesis investigates the microbial diversity of Staphylococcus epidermidis (S. epidermidis) across various anatomical sites in the human body. While traditionally viewed as a benign skin microbe, S. epidermidis also inhabits the urinary, gastrointestinal, and respiratory tracts, raising questions about its genetic variation and adaptability in different environments. The research aims to compare strains of S. epidermidis isolated from the oral cavity, nostrils, urinary tract, and skin of healthy individuals to determine if they share a common ancestor or if they evolved independently in response to specific environmental factors. The study comprises three main aims. Aim 1 focuses on assessing …

Ultramodern Racism: A Critical Discourse Analysis Of The Impact Of Anti-Crt Legislation On Us History Curriculums, Amelia Gernand

Dissertations

In the wake of Donald Trump’s failed 2020 bid for a second presidential term, there was a surge in anti-CRT legislation targeting how issues of race and racism could be taught in public school curricula. While proponents claim that anti-CRT laws will protect students of all races from discrimination, curriculums have historically been used as a tool by those with symbolic power to legitimize white supremacy and perpetuate anti-Black and color-evasive racism. Two states--Florida and Arkansas--recently enacted anti-CRT legislation in addition to Black history mandates. While legislators in these two states claim that their goal is to expand the teaching …

The Forced Sterilization Of Quechua-Speaking Women In Peru: The Role Of Epistemic Injustice In The Perpetration Of Genocide, Geraldine Diaz

Dissertations

The forced sterilization of Quechua-speaking women in Peru from 1996 to 2000 represents a case of genocide in which the state as an epistemic agent has a fundamental role. Although the systematic sterilization was carried out under the guise of a family planning program, the targeting of these women provides strong circumstantial evidence of genocidal intent. According to the testimonies of these women, medical staff, acting on behalf of the government, performed tubal ligation procedures through coercion, threats, lies, bribery, manipulation, and other tactics where the state intentionally withheld information, misinformed women, and failed to obtain proper consent. This research …

Insights On The Cranial Anatomy And Osteohistology Of Cyonosaurus, Alexander Acker

Dissertations

This study investigates the cranial anatomy and life history of the small-bodied gorgonopsian Cyonosaurus. Previous research on gorgonopsians has disproportionately focused on larger members of the clade, leaving smaller forms relatively understudied. This gap has led to several unresolved questions, the most pressing of which concerns gorgonopsian ontogeny. Specifically, it remains unclear whether small-bodied gorgonopsians represent genuinely diminutive adult individuals or juveniles of larger species. The specimen NHCC LB1087 presents an ideal opportunity to address this issue and gain new insights into the biology of small-bodied gorgonopsians. The first chapter focuses on cranial anatomy. Due to the specimen’s preservation, many …

Interactions Between Microplastics, Biofilms, And Antimicrobials In Freshwater Streams, Ryan Thomas Krantz

Dissertations

Microplastics (MPs) are ubiquitous contaminants in freshwater ecosystems that could be hotspots for the interaction of antimicrobial compounds and surface-attached microbial biofilm communities. MPs and antimicrobials are both common in wastewater and urban freshwaters and MPs can adsorb contaminants like antimicrobials to their surface. Within aquatic habitats, MPs also support colonization by microbial biofilms. Therefore, we hypothesized that the adsorption of antimicrobials to MP surfaces would affect microbial communities colonizing MPs, altering their diversity, composition, and antimicrobial resistance. We investigated the effects of these interactions across two studies. The first study, discussed in Chapter 2, used a microcosm approach to …

Including Conscientiously: How Charter School Educators Experience Inclusion Education Implementation, Joe A. Petty

Dissertations

This narrative inquiry examined how charter school educators experience inclusive education implementation while confronting ableist systems that maintain exclusion through seemingly neutral practices. This research emerged from my lived experience of how educational structures systematically marginalize disabled students while appearing progressive. The study investigated two research questions: how support structures and leadership practices either perpetuate or dismantle ableist assumptions embedded in educational practice, and how educators negotiate tensions between implementing evidence-based inclusive strategies and addressing environmental factors that create the need for those strategies.

Data collection employed semistructured interviews with eight credentialed educators across two Southern California charter school sites, …

F-Region Neutral Wind Responses To Magnetospheric Forcing In The Nightside Auroral Oval, Katherine Davidson

Dissertations

High-latitude neutral winds have a number of drivers, both from solar and magnetospheric origins as well as from the lower atmosphere. The efficiency of the individual thermospheric forces, in addition to the relative strength of ion-neutral coupling, are not well characterized. Because of this, the neutral wind response to changes in ionospheric convection is not well understood, with response times ranging on the order of tens of minutes to hours. Using both data driven and modeling simulation efforts, we aim to develop a better understanding of high-latitude ionosphere-thermosphere coupling. In order to do this, three individual studies will be done …

Synthesis Of Poly (L-Glutamine) Of Controlled Chain Length : A Novel Synthetic Approach For Developing Models To Study Polyq Diseases, Nirupama Singh

Dissertations

The abnormal expansion of poly (L-glutamine) repeats beyond a normal threshold (with disease onset at >35 repeat units) has been linked with several neurodegenerative diseases classified as poly (Q) diseases. To investigate the role of this uncontrolled polyQ expansion in disease onset, it is important to understand the changes that occur when the length of poly (L-glutamine) sequences surpasses the normal threshold. To comprehend the role and behavior of these expanded segments, it is essential to develop synthetic techniques that allow polymer production with controlled length. This ensures the accurate representation of healthy and abnormal poly (L-glutamine) segments. However, a …

A Rubber-Band System For Dynamic Incentivization Of Parallelized Gamified Objectives, Nicholas Diliberti

Dissertations

With the advent of videogames as the world's first mass-market interactive media, gamification has emerged as the premier way to harness powerful behavior-affecting gamified elements and place them in other contexts, such as education, fitness, and rehabilitation. This transposition, however, ignores a key tenant of user engagement: reward ought to be aligned with effort. Most, if not all, current gamification systems dispatch static reward allocations for their spread of gamified behaviors. In this paper, an alternative is presented: dynamic gamification. This dynamic gamification reads the user's current gamified state for indicators of aptitude, dynamically remaps rewards with a tuneable evaluation …

Multipoint Observations Of Energetic Particle Acceleration Associated With Corotating Interaction Regions, Ashok Silwal

Dissertations

Stream Interaction Regions (SIRs) play a critical role in energetic particle acceleration and transport in the heliosphere. While shocks and compression regions associated with SIRs can accelerate particles to several MeV energies, most of our current understanding of these events is based on observations near 1 AU and beyond. Observations inside 1 AU, particularly by PSP and SolO, provide a unique opportunity to disentangle the roles of acceleration and transport. This dissertation presents the first detailed measurements of SIR-associated energetic particle events in the inner heliosphere between 0.15 and 0.80 AU using PSP, complemented by SolO and multi-spacecraft observations near …

Mutual Coupling Reduction Techniques In Transverse-Electric-Mode And Hybrid-Mode Microstrip Patch Antenna Arrays, Matthew A. Adams

Dissertations

When the elements of an antenna array are closely spaced, the electromagnetic coupling between them can distort the radiation patterns of the individual elements and change their input impedances, causing significant degradation in the array’s performance. Numerous mutual coupling reduction methods exist in the current literature, each of which allows array elements to be closely spaced while being well-isolated from each other. This dissertation investigates mutual coupling reduction techniques for microstrip patch antenna arrays utilizing elements that excite the fundamental transverse electric (TE) mode. First, a mutual coupling reduction method inspired by the TE-mode microstrip patch cavity model is proposed …

Modeling Solar Wind In The Inner Heliosphere With Quantified Uncertainties, Dinesha Vasanta Hegde

Dissertations

The solar wind (SW) is a vital component of space weather (SWx), providing a background for solar transients such as coronal mass ejections, stream interaction regions, and energetic particles propagating toward Earth. Accurate prediction of SWx events requires a precise description and thorough understanding of physical processes occurring in the ambient SW plasma. This dissertation investigates the effect of uncertainty associated with solar photospheric boundary conditions (BCs) on magnetohydrodynamic (MHD) simulations of the SW in the inner heliosphere. For this purpose, I perform ensemble simulations of the three-dimensional SW flow using an empirically-driven MHD heliosphere model implemented in the Multi-Scale …
