The Use Of Instructional Materials In Elementary Science Classrooms, Mary Jo Hoeft May 2024

The Use Of Instructional Materials In Elementary Science Classrooms, Mary Jo Hoeft

Dissertations - ALL

This mixed methods study explored how elementary teachers reported using a commercially published instructional unit to plan and deliver science instruction in their elementary classrooms. Of particular focus is what elements of the program teachers eliminated during planning and instruction, what outside materials teachers added to instruction, what modifications they made to the materials, and their rationales for these changes to the prescribed program. This study consisted of two phases. The first was a survey of elementary science teachers who taught the Smithsonian Science for the Classroom units. Data collected from this phase informed the subsequent interview phase. I used …

Turbulent Landscapes: Reading The Borders Of Contemporary Latinx And Indigenous Literatures, Florencia Lauria May 2024

Turbulent Landscapes: Reading The Borders Of Contemporary Latinx And Indigenous Literatures, Florencia Lauria

Dissertations - ALL

Engaging with contemporary Latinx and Indigenous border literatures, films, and other cultural productions, my dissertation considers the tensions between Latinx migration and Indigenous sovereignty, claiming that their uneasy relation demands sustained critical and political attention. While Latinx cross-border migration and Indigenous peoples’ sovereignty struggles share important connections in the context of a colonial racial capitalist system of oppression, they cannot be easily collapsed into each other. Expanding upon Marisol de la Cadena’s concept of “partial connection,” my dissertation counters theoretical discourses that insist on commonality as the basis for Indigenous and Latinx intragroup solidarities. Moving beyond Gloria Anzaldúa’s borderlands concept …

“But Is It Worth The Maintenance?”: Exploring The Ways Adolescent Preservice Teachers Develop Teaching Identities And Implement Pedagogical Practices, Tiffany Hamm May 2024

“But Is It Worth The Maintenance?”: Exploring The Ways Adolescent Preservice Teachers Develop Teaching Identities And Implement Pedagogical Practices, Tiffany Hamm

Dissertations - ALL

The climate crisis is an environmental issue that affects people of all walks of life but has disproportionate effects on those living in impoverished communities. The climate crisis therefore is not only an issue of environmental justice, but also social justice. However, incorporating environmental issues within education has typically been left to science classrooms. Teaching for environmental social justice, however, has the potential to extend beyond science content and science classrooms, and instead be incorporated in content across all academic disciplines. This dissertation is a teaching experiment that explored the ways adolescent preservice teachers from various disciplines develop their teaching …

Assessing The Reliability Of The Pairwise Variability Index For Differential Diagnosis Of Apraxia Of Speech, Celeste Sinko May 2024

Assessing The Reliability Of The Pairwise Variability Index For Differential Diagnosis Of Apraxia Of Speech, Celeste Sinko

University Honors Theses

Differential diagnosis of apraxia of speech (AOS) from other speech and language disorders is a prevailing challenge in the field of speech language pathology. Presently, existing measures for assessing AOS consist of perceptual rating scales, such as the Apraxia of Speech Rating Scale developed by Duffy, Strand, Clark, and Josephs. While perceptual rating scales are the current gold standard for assessment and diagnosis of AOS, they require a high degree of clinical expertise, and are susceptible to rater bias and rater drift. Thus, there exists a need for quantitative, objective measures for differential diagnosis of AOS. The purpose of this …

Investigating The Formation Of The Zirconium-Rich Lithologies Of The Grenville Province Using Zircon Thermometry Of Granitoids From The Adirondack Mountains, John St. Denny May 2024

Investigating The Formation Of The Zirconium-Rich Lithologies Of The Grenville Province Using Zircon Thermometry Of Granitoids From The Adirondack Mountains, John St. Denny

Theses - ALL

The Grenville Province (1200-980 Ma) is known to consist of many rocks which are abundant in zircon. This is seen by the large size of Grenville-age zircons and their abundance in the detrital record. A possible explanation for this is the temperature at which these rocks formed. This hypothesis states that the melts which formed the zircon-rich Grenville lithologies were exceptionally high temperature, enabling them to incorporate a significant amount of zirconium. As it is believed that most zirconium in a melt is incorporated into zircon, a high concentration of zirconium in a magma would crystallize an abundance of zircon. …

Behind The Social Media Veil: Exploring The Impact Of Real-World Bias On Transition Probability Inference, Ben Harwood

Dissertations - ALL

This thesis seeks to determine how the probabilistic dynamics of belief can be estimated. More specifically, it explores how effectively those dynamics can be estimated while accounting for the different nuances that arise from social media data in the framework of belief dynamics. Belief dynamics, a sub-discipline of computational social science dating back to 1964, explores the evolution of individual and group beliefs over time. Belief dynamics research delves into facets such as convergence to shared belief, belief interdependence, and clustering. However, there has been a long-standing wall preventing major progress in fully understanding belief dynamics: available data. Social media …

Fire Reconstructions In The Far North: Late Holocene Ecological Responses To Fire In Northern Alaska, Lee Frank-Depue May 2024

Fire Reconstructions In The Far North: Late Holocene Ecological Responses To Fire In Northern Alaska, Lee Frank-Depue

Theses - ALL

Palaeoecological reconstruction can characterize regional fire-regimes and reveal how drivers such as anthropogenic warming and vegetation change influence the fire system. This thesis adds to our knowledge of millennial-scale tundra fire-regimes by creating four new charcoal-based paleoecological records from lake sediment cores on the Alaskan North Slope. Statistical analyses of charcoal accumulation rate (CHAR # particles cm-2 yr-1) at three different size fractions were used to identify centennial-scale variability in biomass burned through time and identify individual fire events. These analyses were coupled with morphological identification and classification of charcoal particles to link charcoal production to hypothesized fuel source. The …

Gauge-Invariant Correlators In Quantum Gravity, Kenneth Ratliff May 2024

Gauge-Invariant Correlators In Quantum Gravity, Kenneth Ratliff

Dissertations - ALL

Recent successes in Euclidean Dynamical Triangulations (EDT) motivate the further comparison of lattice observables to predictions of general relativity (GR) treated as an effective quantum theory. A particularly promising observable is the two-point function of the scalar curvature, which can be straightforwardly computed on the lattice and which in principle can also be computed from the Einstein-Hilbert path integral. Any such comparison should be between manifestly gauge-invariant observables, and will require that the GR predictions be analytically continued in a gauge-invariant manner to the Euclidean signature of the lattice. In this thesis I present my work toward this goal, namely: …

Defects And Deformation In Passive And Active Structural Glasses, Julia Ann Giannini

Dissertations - ALL

Glasses and disordered granular media represent a class of materials that are quite familiar to us, from the glass in windows and phone screens, to piles of fruits, grains, and sand. Further, living and active systems such as cellular tissues, collections of robots, and even human crowds behave as disordered solids when they are gathered at high enough densities. Despite their ubiquity, there are still many behaviors of these amorphous systems that lack a full understanding. Contrasting crystalline solids, the thermodynamic, vibrational, energetic, and mechanical properties of glasses are not well-characterized by solid state theory. In the case of active …

Multimode Metamaterial Ring Resonator As An Entangling Bus For Artificial Atoms, Tianna Carroll

Dissertations - ALL

Circuit quantum electrodynamics (cQED) systems with superconducting qubits coupled to linear microwave resonators are a prominent platform for realizing scalable quantum information processors. Combining cQED architectures with multimode resonators leads to a broad set of applications for performing analog quantum simulation, implementing dense quantum memory, and generating multimode entangled states between physically distant qubits. Microwave resonators in cQED are typically formed from distributed transmission lines that exhibit conventional dispersion with harmonic mode spacing; in such systems, usually only a single resonant mode can be strongly coupled to a qubit. Superconducting metamaterial resonators comprised of lumped circuit elements can be designed …

The Functoriality Of Odd Khovanov Homology Up To Sign And Applications, Jacob Migdail-Smith May 2024

The Functoriality Of Odd Khovanov Homology Up To Sign And Applications, Jacob Migdail-Smith

Dissertations - ALL

Odd Khovanov Homology is a homological invariant of knots and links that permits a Bar-Natan category presentation. In this dissertation, we extend the odd Khovanov bracket to link cobordisms and prove that our construction is functorial up to sign. We then build an odd Khovanov theory for dotted link cobordisms. Out of the dotted theory, a module structure on the odd Khovanov homology of a diagram over the exterior algebra of the diagram’s coloring group arises. We finish by using our functoriality result to prove that if n is even or if the knot has even framing, then the odd …

Investigating Holography Using Classical And Quantum Simulations, Goksu Can Toga May 2024

Investigating Holography Using Classical And Quantum Simulations, Goksu Can Toga

Dissertations - ALL

In this thesis, we aim to develop classical and quantum simulations to test holography. Holography can be thought of in its most basic form as a duality that relates a d + 1 dimensional theory to a d dimensional one and the most famous holographic correspondence is the AdS/CFT duality where d + 1 dimensional weakly coupled gravity theory is related to a d dimensional CFT. We start by developing lattice simulations for the N = 4 super Yang-Mills model and explore an improved supersymmetric lattice action showing that it is free of the lattice artifacts that plagued earlier lattice …

Fea Simulations For Thermal Distributions Of Large Scale 3dic Packages, Suxia Chen, Qiang Wu, Wayne Xun, Jiachen Zhang, Jianping Xun

Computer Science Faculty Publications and Presentations

As the market increases for Artificial Intelligence and High-Performance Computing applications, the geometry of 3-Dimensional Integrated Circuit packages becomes more complicated; therefore, predicting the thermal distributions of the structures becomes not only more important but also more challenging. The physics governing the thermal distribution is a 3-dimensional partial differential equation. In order to predict the thermal distributions, various approaches such as the layer modeling method have been invented. While practical, these approaches solve a simplified version of the differential equation placing an inherent limitation on their capabilities which may be improved upon. In this research we solve the actual differential …
