Culturally Responsive Social-Emotional Training And Supplemental Resources For Early Childhood Teachers, Danielle Johnson

Masters Projects

Black students are overrepresented in discipline and behavior referrals in the early childhood setting. Given the increasing need for young black children to learn social emotional skills, how can teachers effectively support them with inadequate curriculum? There is significant research that shows the possible reasons why there is an over representation of black students being labeled as a behavior problem in early childhood educational settings. These reasons can create a negative cycle for black students causing much harm to their education and their views of school. Teachers can attempt to resolve this issue by implementing a culturally responsive Social-Emotional Learning …

Tag-Based Security In C: Writing And Specifying Flexible Protection, Sean Noble Anderson

Dissertations and Theses

The C language is ubiquitous and insecure. Tag-based security policies offer a flexible toolkit for runtime protection, including policies that mitigate the effects of undetected programming bugs and those that enforce security properties of the program logic. But tag policies can be difficult to define, and the protection that they offer can be difficult to specify and to prove.

This dissertation builds from an assembly-level specification of stack safety, encompassing the essential control-flow structure of C and other high level languages, to a C source-level policy definition framework called Tagged C. Tagged C includes a variant C semantics parameterized by …

Investigating Student Expectations, Buy-In, And Engagement In Lower Division Undergraduate Chemistry Labs, Elizabeth Blanche Vaughan

Dissertations and Theses

Laboratory courses constitute an integral aspect of chemistry education at the undergraduate level. Despite their prominence, a growing number of researchers have begun to think more critically about the value of laboratory learning experiences. As pedagogical decisions should be based on evidence, it is necessary for chemistry education researchers and practitioners to investigate the claim that teaching laboratories are a valuable part of science education.

Landslide Mapping, Characterization, And Hazard Assessment With 3d Slope Stability Modeling In White Bluffs, Washington State, Anna Tsitsivas

Dissertations and Theses

Slope failures shape the landscape by moving unstable material downslope and, in doing so, become a great hazard to all those in their path. Understanding the mechanisms that control landslide location, timing, size, type, and runout - and therefore hazards - requires a deep understanding of the local geology, stratigraphy, and groundwater conditions. Along White Bluffs, in south-central Washington, landslides of several failure styles have likely been triggered by an increased water table in recent decades, threatening both farmland behind the bluffs and habitat below. This study focuses on characterizing potential groundwater sources and determining controls on spatial and temporal …

Trebuchets Were Not Siege Guns, So Why Use Them?, Michael S. Fulton

'Atiqot

Counterweight trebuchets were the most powerful ballistic weapons of their day, but their association with later siege guns has led to misunderstandings of their destructive capabilities. This article is an attempt to correct some misguided ideas by providing a short overview of the power and value of mechanical artillery and contextualizing its use in the Levant during the twelfth and thirteenth centuries. After addressing the origin of certain theories that these engines were far more destructive than seems to have been the reality, a brief assessment of their actual power is conducted by looking at the ways sources exaggerate the …

Automated Text Scoring In The Age Of Generative Ai For The Gpu-Poor, Chris M. Ormerod, Alexander Kwako

Chinese/English Journal of Educational Measurement and Evaluation | 教育测量与评估双语期刊

Abstract Current research on generative language models (GLMs) for automated text scoring (ATS) has focused almost exclusively on querying proprietary models via Application Programming Interfaces (APIs). Yet such practices raise issues around transparency and security, and these methods offer little in the way of efficiency or customizability. With the recent proliferation of smaller, open-source models, there is the option to explore GLMs with computers equipped with modest, consumer-grade hardware—that is, for the “GPU poor.” In this study, we analyze the performance and efficiency of open-source, small-scale GLMs for ATS. Results show that GLMs can be fine-tuned to achieve adequate, though …

A Text-Linguistic Analysis Of Deliberative Discourse In Hebrew With Review Of The Lxx Translation, Timothy C. Lang

Masters Theses

This thesis intends to demonstrate that linguistics, specifically the text-linguistic (TL method), may be practically applied to biblical translation and interpretation. Consequently, one may use text-linguistics to discover the biblical author’s intended meaning expressed through the structure of the text. Foundationally, the work of Robert Longacre and Kenneth L. Pike is applied. Functionally, this thesis tests the process described in the dissertation of Ewell Ray Clendenon. While the word test is used, the test is not intended to validate or invalidate the TL method. Rather, the test is analogous to that of a mathematician whereby a proof test is applied …

Verbal Working Memory And Syntactic Comprehension Segregate Into The Dorsal And Ventral Streams, Respectively, William Matchin, Zeinab K. Mollasaraei, Leonardo Bonilha, Chris Rorden, Gregory Hickok, Dirk Den Ouden, Julius Fridriksson Ph.D.

Faculty Publications

Syntactic processing and verbal working memory are both essential components to sentence comprehension. Nonetheless, the separability of these systems in the brain remains unclear. To address this issue, we performed causal-inference analyses based on lesion and connectome network mapping using MRI and behavioural testing in two groups of individuals with chronic post-stroke aphasia. We employed a rhyme judgement task with heavy working memory load without articulatory confounds, controlling for the overall ability to match auditory words to pictures and to perform a metalinguistic rhyme judgement, isolating the effect of working memory load (103 individuals). We assessed non-canonical sentence comprehension, isolating …

The first article is a review of the literature on what researchers have learned about AR in learning, systematically identifying six areas that appear salient yet underrepresented in the literature. The second article expands further upon this theme by conducting a qualitative study …

Enhancing Cybersecurity Strategies Through Automated Cti Extraction, Risk Prioritization, And Privacy-Conscious Information Sharing, Spencer Rian Massengale

Theses and Dissertations

Cybersecurity operations require the ability to collect and analyze large amounts of cyber threat intelligence (CTI) to assess risks and formulate defensive strategies against emerging threats. This task has become increasingly complex due to the rapid evolution of cyber threats and the growing volume of unstructured, natural-language CTI sources. The scale of data and analysis needed to utilize CTI effectively far exceeds humans' manual capacity, especially for organizations with limited resources. This research focuses on leveraging Large Language Models (LLMs) and machine learning techniques to enhance CTI extraction, risk assessment, and data sharing. We utilized LLMs to automate the extraction …

New Insights Into Supradense Matter From Dissecting Scaled Stellar Structure Equations, Bao-Jun Cai, Bao-An Li

Faculty Publications

The strong-field gravity in general relativity (GR) realized in neutron stars (NSs) renders the equation of state (EOS) P(ε) of supradense neutron star matter to be essentially nonlinear and refines the upper bound for ϕ≡P/ε to be much smaller than the special relativity (SR) requirement with linear EOSs, where P andεare respectively the pressure and energy density of the system considered. Specifically, a tight bound ϕ ≲ 0.374 is obtained by perturbatively anatomizing the intrinsic structures of the scaled Tolman–Oppenheimer–Volkoff (TOV) equations without using any input nuclear EOS. New insights gained from this novel analysis provide EOS-model-independent constraints on the …

How Does Augmentation Affect Feature Space: A Study Using Various Augmentation Methods In Distributed Learning, Nikil Sharan Prabahar Balasubramanian

Computer Science Theses

This thesis examines the impact of data augmentation techniques on model performance within a distributed learning framework, focusing on enhancing feature diversity and improving representation for under-represented classes. Data augmentation, commonly used to address data imbalance, significantly influences the feature space learned by deep learning models, with varied effects in distributed settings where data is split across nodes. Our study reveals that inconsistencies in feature learning across nodes reduce the benefits of local augmentation in capturing complex patterns, leading to suboptimal model performance. To address this, we propose a coherent augmentation approach that embeds consistent transformations in the central server, …
