Conducting Culturally Responsive, Strengths-Based Assessment In Schools, Eileen Cullen

Electronic Theses and Dissertations

Special education assessment has a significant impact on the lives of children with disabilities and their families. However, traditional assessment practices have been critiqued as being deficit-based, overly focused on “labeling” students, and failing to provide a holistic understanding of the student. Assessment models such as strengths-based assessment (SBA) and culturally responsive assessment (CRA), have potential to addresses these critiques and be more appropriate for the growingly diverse school population. Despite this, these models of assessment are under studied and there is a lack of clear guidance for how practitioners should implement them.

In these manuscripts, CRA and SBA are …

A Geospatial And Machine Learning Framework For Forecasting Ground Level Ozone Pollution, William J. Keenan

Electronic Theses and Dissertations

The major detrimental health effects of ground-level ozone (GLO) pollution make it imperative that both policy makers and ordinary citizens have access to high accuracy, high-resolution forecasts of their local area. Recently, advancements in computing power have made it possible to apply artificial intelligence (AI) techniques to a variety of big data modelling problems, including GLO forecasting and estimation. Of these AI methods, deep neural networks (DNN) have demonstrated the highest accuracy due to their ability extract non-linear relationships from high dimensional, noisy data inputs.

This research effort uses novel data sources, namely NOAA’s High Resolution Rapid Refresh (HRRR) meteorology …

Changing The Narrative: Student Empowerment In Unequal School Contexts, Stephanie A. Nisle-Mikos

Electronic Theses and Dissertations

Educational experiences affect a wide variety of life outcomes for individuals. The type of education an individual receives influences their occupation, the neighborhood in which they live, and even their risk of mortality (National Research Council, 2013; Sasson, 2016). In particular, the life trajectories of students who attend high-poverty schools are not the same as youth who attend schools with greater resources (National Center for Education Statistics [NCES], 2013; Taylor, 2005). In this dissertation, I provide a brief background on current rates of disproportionality in education and examine how specific theoretical constructs and educational policies may be used to explain …

How Well Do Nature-Based Solutions To Climate Change Address Gender Equity?, Stephanie Efua Yamoah

Electronic Theses and Dissertations

As the climate crisis continues to deepen, there have been calls for adaptation and mitigation approaches that rely on nature-based solutions. These solutions are approaches that offer the potential to reduce and remove greenhouse gas emissions. Examples include forest restoration, coastal wetland conservation, and no-till agriculture, among other practices. In this thesis, I employ an intersectional feminist political ecology perspective to critically examine the integration of gender equity within such nature-based solutions. I make two interrelated arguments using a qualitative methodology and an intensive case study of three projects in Ghana. First, I argue that women’s participation in nature-based solutions …

Characterization Of Oxidized Tau Protein Aggregation And Inhibition Of Tau Aggregation Via Map2, Brad Krzesinski

Electronic Theses and Dissertations

Neurofibrillary tangles (NFT) composed of the microtubule stabilizing protein Tau are a pathological hallmark of Alzheimer's disease (AD) and many other dementia related diseases specified as Tauopathies. Due to alternative mRNA splicing, intrinsically disordered Tau exists as six separate isoforms in the adult human brain where they are categorized by the lack or inclusion of the second repeat in the microtubule binding domain (3R or 4R respectively). Isoforms are subcategorized by the inclusion or lack thereof, one or two N-terminal inserts. Many studies show that Tau aggregates into amyloid fibrils and these fibrils can break into small oligomeric units known …

Progressive Paradox In Political Rhetoric: The Hart-Celler Immigration Act Of 1965, Amanda Rolston Henderson

Electronic Theses and Dissertations

This dissertation investigates the interplay between U.S. norms for inclusion, the embedded role of religion within these norms, and how political rhetoric challenges or sustains them. Using a historical lens, I outline key moments in U.S. history, unravel central ideologies entrenched in U.S. narratives, and illuminate the ideographic function of the key concepts land, family, and work. These terms serve as conduits for conveying complex systems of meaning, which are entrenched in societal assumptions and concretized through political discourse and action.

These dynamics are demonstrated in a case study of the discourse surrounding the Hart-Celler Immigration Act …

Balancing Act: Navigating Employee Autonomy And Neglect, Lekshmy Sankar

Electronic Theses and Dissertations

The fine line between granting employee autonomy and inadvertently falling into patterns of neglect presents a complex challenge within organizational leadership. This study explores the question: What do leaders perceive as effective strategies for providing autonomy to remote employees without being perceived as neglecting them? Employee autonomy empowers employees to make decisions, while leader neglect towards subordinates (LNS) is defined through this research as a gradual decrease in a leader's interest or effort in sustaining positive relationships with employees. Navigating this balance is crucial to maintaining employee engagement.

This qualitative study uncovered nuanced perceptions on this issue using a grounded …

Morphological Remodeling Of The Endoplasmic Reticulum During Mitosis And Its Influence On The Integrity Of The Spindle Apparatus, Katie R. Rollins

Electronic Theses and Dissertations

The Endoplasmic Reticulum (ER) is the largest organelle in the cell by surface area and forms contacts with other organelles throughout the cell. In recent work, the ER has been implicated in numerous processes within the cell beyond its canonical roles of protein synthesis and calcium storage. The ER also undergoes a remarkable transition in morphology during cell division, with mitotic divisions requiring a massive remodeling of various membranous organelles such as the nuclear envelope and Golgi. However, whether changes in ER behaviors modulate mitotic events is less clear. The rapid cleavage divisions in the early Drosophila embryo are a …

Rhetorical Resonances: An Affective Logic Of Emergence In Space And Time, Craig R. Weathers

Electronic Theses and Dissertations

This project explores the affective circulation of controversy in contemporary public discourse through a rhetorical ecological approach. It addresses the problem of how flattened conceptions of power and social movements cast in binary opposition prevent effective deliberation around public controversies. The research method involves analyzing three case studies through a new framework for rhetorical studies, called a logic of emergence, to consider the resonance and trajectories of actants (individuals, groups, and institutions) in conflict. The first case study examines the Unite the Right rally in Charlottesville and the discursive equating of antifa and the Alt-Right. The second case analyzes the …

The Entrepreneur’S Burden: Investigating The Interplay Between Impostorism And Entrepreneurial Identity, Megan Laura Weber

Electronic Theses and Dissertations

Entrepreneurship is often portrayed as a glamorous pursuit of success but conceals a darker side, exacerbated by impostorism, characterized by challenges, identity conflicts, and diminished well-being. This "dark side" of entrepreneurship is seldom explored due to our collective fascination with the central figure of the entrepreneur. Impostorism is a prevalent phenomenon among individuals who perceive that their role is beyond their capabilities and fear being exposed as a "fake." Impostorism can have negative consequences, including self-sabotage, missed opportunities, and difficulty in seeking help or support, which can impact the ability of entrepreneurs to take entrepreneurial action and experience well-being.

The Aquatic Microbial Environment Shapes The Gut Microbiota, Brain, And Behavior Of Larval Amphibians, Kyle Emerson

Electronic Theses and Dissertations

Microbial communities comprising bacteria, viruses, fungi, and protists live within and on the surfaces of animal hosts. These microbial communities exist in symbiosis with the host, and heavily influence host physiology, development, health, and fitness. Gut-dwelling microbes (i.e., gut microbiota) contribute to host neurodevelopment through a bidirectional Microbiota-Gut-Brain (MGB) axis. Evidence of the MGB axis has been primarily derived from studies that use germ-free (GF) models, which commonly display altered neurophysiology and behavior compared to conventionally raised counterparts. Almost all studies of the MGB axis have used mammalian models in a biomedical framework, leaving a knowledge gap regarding the role …

Using Self-Assessment Tools And Complementary Alternative Therapy For Chronic Migraines In Menopausal Women, Krystal Rachelle Bridwell

Electronic Theses and Dissertations

Abstract

Migraine headaches are ranked as one of the highest disabling conditions in the United States. Women who are in the perimenopausal transition phase have a higher prevalence of disabling migraines that can result in a decreased quality of life, loss of income, decreased productivity, and a higher risk for emotional difficulties. The gap in practice is the lack of education on complementary alternative medicine (CAM) and the use of a migraine diary to recognize individual symptoms as a substitute or cotherapy with pharmacologic treatments. The purpose of this scholarly project was to improve clinical practice and outcomes for perimenopausal …

The Multipurpose Dna Repair/Redox Protein Ape1 In Rodent And Human Lewy Body Disease, Kristin Marie Miner

Electronic Theses and Dissertations

Lewy body disorders are a family of neurodegenerative conditions characterized by proteostatic and redox disequilibrium, leading to deposition of the abundant protein α-synuclein in hallmark inclusions and oxidative damage to DNA. Sublethal oxidative DNA damage in neurons is repaired predominantly by the base excision repair pathway, which involves the coordinated activity of several enzymes, including apurinic/apyrimidinic endonuclease 1 (APE1). Despite emerging connections between α-synuclein, oxidative stress, and DNA damage/repair, along with evidence demonstrating the multifunctional nature of APE1, the link between APE1 and α-synuclein has not yet been explored.

Here, we conducted a broad investigation of APE1 in the context …

Design, Synthesis, And Biological Evaluation Of Novel Heterocyclic Compounds For The Treatment Of Cancer And Neurodegenerative Disorders, Saloni Patel

Electronic Theses and Dissertations

Alzheimer's disease (AD) is a progressive neurodegenerative disease that impairs memory and cognitive judgment, mostly in older people. It is the leading cause of dementia in late adult life. The hallmarks of AD include neuronal loss, neuroinflammation, a build-up of extracellular amyloid beta (Aβ) plaques, intracellular neurofibrillary tangles, and extracellular neuritic plaques. Current treatment, although useful, is not adequate. Identification of therapeutic agents with the potential to alter the progress of AD is a high priority. Recent studies suggest that the Sigma-2 receptor is an attractive target for the development of disease-modifying AD drugs. Preventing the binding of Sigma-2 receptors …
