Teachers' Experiences With Teaching For Social Justice In Tracked Middle School Mathematics Classes., Stephanie Jean White May 2024

Teachers' Experiences With Teaching For Social Justice In Tracked Middle School Mathematics Classes., Stephanie Jean White

Electronic Theses and Dissertations

Tracking is a longstanding structure in K-12 mathematics that decades of research has shown to be inequitable. Despites calls to detrack mathematics classes, most U.S. schools retain tracking. Mathematics educators have attempted to implement teaching pedagogies such as Teaching for Social Justice (TSJ) that promote equity in all mathematics classrooms, including tracked classes. This research used the Learning to Teach for Social Justice Belief (LTSJ-B) Scale with middle school mathematics teachers who have taught in tracked classes to measure their levels of commitment to TSJ. This research also employed case study methodology with three teachers and cross-case analysis using TSJ …


Authentic Fake: Authenticity And Authentication., Suyun Son May 2024

Authentic Fake: Authenticity And Authentication., Suyun Son

Electronic Theses and Dissertations

My thesis exhibition questions the modern sanctification of authenticity. No longer believing in objective truths, the postmodern society seeks epistemic grounding on being true to oneself. The categories of authentic-or-fake replaced the binary of true-or-false. But authenticity is a trojan horse for authentication. As a Korean American artist, I'm encouraged to express my “authentic” Korean identity. This encouragement can also imply my works will receive recognition as authentic and meaningful only when they embody Korean cultural expression. Authenticity becomes a performance for the sake of authentication. Ironically, authenticity turns into an act of conformity/confirmation. Authenticity demands you stay true to …

Exploring Resilience With Neuroimaging: Moderators Of The Impacts Of Childhood Traumatic Stress On Fear Processing., Karisa June Hunt

Electronic Theses and Dissertations

Childhood trauma is an alarming public health crisis, and the field of trauma research is relatively underdeveloped given population rates of childhood trauma and post-trauma pathology. Even less studied than the impacts of trauma are the impacts of resilience, and the protective factors that foster it. It is widely acknowledged that an investigation of trauma is incomplete without an investigation of its impacts on fear processing. Understanding the neural underpinnings of resilience to childhood trauma during fear conditioning is vital to the development of therapeutic interventions able to moderate its devastating impacts. The present study investigated the complex neurobiological interplay …


Development And Evaluation Of A Modeling Platform For Evaluating Immunotherapeutic Efficacy In The Tumor Microenvironment., Dylan Andrew Goodin May 2024

Development And Evaluation Of A Modeling Platform For Evaluating Immunotherapeutic Efficacy In The Tumor Microenvironment., Dylan Andrew Goodin

Electronic Theses and Dissertations

The tumor microenvironment (TME) represents the complex outcome of numerous tumor, stromal, and immune interactions, and whose composition can significantly affect treatment response. Particularly, immunotherapeutic efficacy is subject to multiple tumor-specific TME interactions that may be difficult to evaluate/predict clinically. Mathematical modelling has been formulated to evaluate specific aspects of the TME, including vasculature, ECM deposition, and immune-tumor interactions. However, the computational challenge of simulating multiple TME interactions has led to sacrificing varying degrees of model generalizability and clinical relevance. This work describes increased computational performance of a 3D continuum model that simulates tumor tissue, ECM, and vasculature using a …


Strategy-Proof Social Choice Functions On Condorcet Domains., Flannery Marie Musk Wells May 2024

Strategy-Proof Social Choice Functions On Condorcet Domains., Flannery Marie Musk Wells

Electronic Theses and Dissertations

A social choice function is said to be strategy-proof if no voter has any motivation to lie about their true preference. Strategy-proofness is a desirable property of social choice functions so we consider here functions that always satisfy this property. We add to this property the additional desirable conditions of anonymity and neutrality and present domains on which we can get a characterization of majority rule as the only social choice function that satisfies these three properties. Furthermore, we consider what functions look like when we drop the condition of anonymity.

Using Dynamic Schemas For Query Optimization Over Json Data., Tomas Felipe Llano-Rios May 2024

Using Dynamic Schemas For Query Optimization Over Json Data., Tomas Felipe Llano-Rios

Electronic Theses and Dissertations

Query optimization in document stores has traditionally relied on rule-based approaches, but recent research advocates for a shift towards cost-based optimization. However, this transition is hindered by the fragmented nature of existing approaches, stemming from the early development stage of cost-based query optimization for document databases. A key challenge lies in the absence of a standardized query language and semantics, exacerbated by the diverse and schema-less nature of JSON document collections. To tackle these challenges, the literature has proposed dynamic schemas, primarily utilized at parsing time. However, these schemas lack a formal foundation that describes meaningful semantics for query optimization. …
