Analysis Of Approximations In Flash Thermal Diffusivity Measurements Using High‑Fidelity Simulations, Tage T. Burnett, Jakob G. Bates, Matthew R. Jones, Christopher R. Dillon, John Tencer May 2026

Analysis Of Approximations In Flash Thermal Diffusivity Measurements Using High‑Fidelity Simulations, Tage T. Burnett, Jakob G. Bates, Matthew R. Jones, Christopher R. Dillon, John Tencer

Faculty Publications

Thermal diffusivity is an important material property for understanding and characterizing transient behavior in many heat transfer applications. This study investigates the accuracy and approximations of inverse mathematical models for measuring thermal diffusivity of materials via the widely used Flash Method. High-fidelity simulations of the Flash Method in copper, silicon carbide, silicon, and glass were performed as numerical experiments and included physics such as in-depth absorption, radial conduction, and surface convection. Data from those numerical experiments were used to estimate material thermal diffusivity using seven traditional and new inverse models. Parker’s original model had relative errors 𝜖< 5% when the approximations it makes were enforced in numerical experiments. Newer models performed well even when experimental restrictions were relaxed. Models that include radial heat conduction were capable of accurately measuring thermal diffusivity (𝜖< 1%) when a Gaussian energy source was used. Models with radial conduction and in-depth material absorption of the laser source could calculate thermal diffusivity for semi-transparent materials such as silicon (𝜖< 1%) and even transparent materials like glass (𝜖< 10%). Convective losses from the material’s front surface had a negligible impact on measurements except for very low thermal diffusivity materials. Using temperatures from many locations of the test material’s surface increased resilience to noise, reducing the distribution of thermal diffusivity measurements by more than an order of magnitude. The models developed in this study could enable a more relaxed Flash Method experimental setup that maintains thermal diffusivity accuracy and extend the utility of the Flash Method to semitransparent materials.


Invoking The Senior Partner, Yoshihiko Ariizumi May 2026

Invoking The Senior Partner, Yoshihiko Ariizumi

Spiritual Proficiency

For faculty who hold religious faith, the relationship between scholarly work and divine communion is not a private afterthought but a potential cognitive and motivational resource of the first order. This article draws on ten converging theoretical frameworks in organizational psychology, positive psychology, and learning science to argue that actively seeking divine guidance through prayer — treating Heavenly Father as a Senior Partner in the research enterprise — is not a retreat from rigorous scholarship but an extension of it. We examine how practices of spiritual seeking interact with flow states, resilience, intellectual humility, and prospective thinking to produce measurable …

What Makes Leaders In Human Services Effective? A Pilot Study Linking Systems Thinking, Perspective-Taking, And Leadership Success, Ryan Witterschein

Journal of Nonprofit Innovation

Leadership effectiveness is a persistent challenge in human services nonprofits, where organizations serving individuals with disabilities and complex needs have grown dramatically but lack validated tools for assessing the cognitive competencies that distinguish effective leaders. This quantitative pilot study introduces the ABA Leadership Assessment Tool version 2.0 (ABLA 2.0), a 48-item instrument integrating transformational and transactional leadership frameworks with three constructs from Relational Frame Theory—perspective-taking, temporal reasoning, and systems thinking. Eight Board Certified Behavior Analysts in organizational leadership roles completed the assessment, yielding 100% completion and strong preliminary reliability across all subscales (α = .71–.94). Leaders who demonstrated stronger cognitive …


Separating Access Legitimacy From Utilization Analytics: A Two-Layer Evaluation Model For Philanthropy And Development, Stephanie Zabriskie Apr 2026

Separating Access Legitimacy From Utilization Analytics: A Two-Layer Evaluation Model For Philanthropy And Development, Stephanie Zabriskie

Journal of Nonprofit Innovation

This article introduces a two-layer evaluation model for philanthropic and development decision-making in access-based interventions. The first layer treats Access as Outcome (AAO) as a recognized outcome when essential goods, services or resources are delivered through a viable delivery pathway, without requiring post-access utilization or compliance to validate legitimacy. The second layer evaluates post-access variation through System Coherence Conditions (SCC), defined as internal alignment across governance and decision-making, distribution and logistics, social accountability and norms, and scarcity management and continuity, which explain differences in utilization, continuity, and downstream effects as signals of system coherence rather than as retroactive worthiness thresholds. …


A Case For Mtor Pathway Screening In Early Epilepsy Diagnosis, David Seamons Apr 2026

A Case For Mtor Pathway Screening In Early Epilepsy Diagnosis, David Seamons

Student Works

Mutations in the mTOR pathway can give rise to epileptic seizures in patients. While a variety of antiepileptic drugs are available to treat epilepsy, a large proportion of patients will experience refractory seizures (Chen et al., 2018). Additionally, patients with mTOR-related epilepsy may experience reduced efficacy in traditional therapeutic options to treat seizures (French et al., 2016; Hadzsiev et al., 2023; Kato et al., 2022; Moloney et al., 2023). Mutations resulting in mTOR-related epilepsy are genetically inherited; however, some variability in family histories of epilepsy may be due to second-hit somatic mutations in focal areas of the brain (Dawson et …


Evaluation Of Quantification Methods Applied To Overlapping Ftir Features, Benjamin P. Diehl Apr 2026

Evaluation Of Quantification Methods Applied To Overlapping Ftir Features, Benjamin P. Diehl

Reviews, Analyses, and Instructional Studies in Electrochemistry (RAISE)

Quantifying overlapping FTIR spectral features is critical for electrochemical analysis but often requires complex deconvolution. This work systematically evaluates several area ratio and proxy-based quantification methods using a controlled synthetic spectral model with varying signal-to-noise ratio, peak spacing, width, background, and data resolution. Constrained peak fitting and fixed-window integration consistently exhibit near-perfect monotonicity (Spearman ≈ 1.000) and linearity (Pearson ≈ 0.999–1.000) across all conditions. In contrast, derivative and moment-based metrics show sensitivity to peak overlap, width, and background. These results demonstrate that physically grounded area-based methods provide the most robust and reliable quantification of overlapping FTIR features.


The Low-Temperature Heat Capacity And Thermodynamic Functions Of Mg3n2, Ca3n2, And Sr3n2, Natalie Parkinson Apr 2026

The Low-Temperature Heat Capacity And Thermodynamic Functions Of Mg3n2, Ca3n2, And Sr3n2, Natalie Parkinson

Undergraduate Honors Theses

Alkaline earth nitrides are highly hygroscopic materials used in metal refinement and various synthetic processes. In this work, the low-temperature heat capacities of Mg3N2, Ca3N2, and Sr3N2 were measured for the first time. The Ca3N2 sample contained impurities, necessitating corrections to the heat capacity data. The absolute entropies of Mg3N2, Ca3N2, and Sr3N2 at 298.15 K were determined to be 75.1, 114.9, and 188.5 J∙K−1∙mol−1, respectively. Gibbs energies of formation were …

Foreign Language Experience Effects On L2-Accented Speech Attitudes In College Students, Jordan L. Ellington

Theses and Dissertations

The purpose of the study is to test whether knowledge of a second language in college students can affect perceptions and prejudices towards speakers with foreign accents. The testing was completed through both implicit and explicit attitudinal measures in regard to recorded audio stimuli. The explicit attitudinal testing was performed through participant self reporting of attitudes. Participants were presented with first (L1) or second (L2) language accented English samples and then rated that speaker in terms of various characteristics or traits that represented the speaker's solidarity and status. The implicit testing was performed in an Auditory Implicit Associations Test on …


Modified Anodic Stripping Voltammetry For In Situ Analysis Of Liquid Metal Composition In Molten Salt Electrorefining Systems, James H. Manner Apr 2026

Modified Anodic Stripping Voltammetry For In Situ Analysis Of Liquid Metal Composition In Molten Salt Electrorefining Systems, James H. Manner

Reviews, Analyses, and Instructional Studies in Electrochemistry (RAISE)

The development of in-situ analytical techniques for high-temperature molten salt systems is critical for advancing electrorefining in nuclear fuel recycling and metallurgical purification. This study proposes Modified Anodic Stripping Voltammetry (MASV), using a “dip-and-strip” approach where a tungsten electrode captures molten Sn–Ni alloy before stripping in LiCl–KCl–CaCl₂ at 415 °C. OCP results showed rapid loss of the metal layer due to poor wetting, and stripping peaks gave compositions inconsistent with the alloy, likely reflecting Sn/Sn²⁺ and Sn²⁺/Sn⁴⁺ redox processes. These results highlight interfacial limitations and the need for improved electrode materials and surface modification.


Recognizing Metaphorical References To Sexual Assault Resistance And Represented Rape Myths In Coraline (2009), Braden Slater Apr 2026

Recognizing Metaphorical References To Sexual Assault Resistance And Represented Rape Myths In Coraline (2009), Braden Slater

Theses and Dissertations

Is there any value in children’s horror literature and film? Literary theorists have shown that children’s horror is uniquely positioned to be not only captivating and accessible, but also educational and hopeful for some young audience members. Like most fictional monsters, those presented in children’s horror can be read as metaphors for the fears and experiences people face in real life. Scholars have argued that engaging with this type of frightening media may help people confront challenging ideas and feelings from a place of safety. Building on this theoretical foundation, I perform a close reading of the 2009 film Coraline, …


Exploring Subject-Verb Agreement Challenges Among Third-Grade Portuguese Dual Language Immersion Students: A Mixed-Methods Study, Marisa Tobias Apr 2026

Exploring Subject-Verb Agreement Challenges Among Third-Grade Portuguese Dual Language Immersion Students: A Mixed-Methods Study, Marisa Tobias

Theses and Dissertations

Dual Language Immersion (DLI) programs are commonly recognized for supporting the development of oral proficiency; however, persistent challenges with grammatical accuracy, particularly subject-verb agreement, remain common among elementary-aged learners. This mixed-methods study focuses on third-grade students in a Portuguese DLI program and examines how they use present-tense verb forms in different classroom contexts. Drawing on classroom observations, instructional materials, and students’ oral and written production, the study analyzes the nature of the input learners receive and the types of errors that persist during oral communication. Findings indicate that students demonstrate greater accuracy during structured tasks, while difficulties with subject-verb agreement …


Differentiable Objectives For 3d Scene Relighting Via Gradient Descent On Olat Basis Coefficients, Anson Savage Apr 2026

Differentiable Objectives For 3d Scene Relighting Via Gradient Descent On Olat Basis Coefficients, Anson Savage

Theses and Dissertations

Designing effective lighting is an iterative and often time-consuming process. This work contributes to automatic lighting design research by presenting a render-engine agnostic optimization routine: gradient descent on RGB multipliers of one-light-at-a-time (OLAT) basis images. We compare several objective functions to accomplish lighting tasks and show that our method is capable of quickly and effectively exploring different lighting styles using either text prompts or reference images. We also present several datasets specific to lighting tasks and show that fine-tuning on these datasets can improve performance.


These Wretched Waters: A New Perspective On The Myth Texts And Visual Adaptations Of The Danaids, Tessa Haney Apr 2026

These Wretched Waters: A New Perspective On The Myth Texts And Visual Adaptations Of The Danaids, Tessa Haney

Theses and Dissertations

Both Greek and Latin texts regarding the Danaids are rife with gestational imagery and vocabulary. This textual focus on chthonic, symbolic aparturience coheres with both Greek and Roman perceptions of femininity. Women in both cultures were socially mandated to marry, have children, and confine themselves to the domestic sphere. The Danaids’ refusal to participate in this system would have been viewed as a breach of cosmic order, and a punishment that grounded the sisters in their 'traditional’ femaleness would have been viewed as a solution to such a breach. While early modern visual adaptations of the Danaid myth lack gestational …

This qualitative case study investigates the experiences and practices of successful independent English as a Foreign Language (EFL) teachers in Brazil who operate outside traditional schools and private language institutes. Rather than providing a broad descriptive profile, this study offers an in-depth examination of a small group of teachers. These educators frequently use social media platforms such as Instagram and Facebook to showcase communicative, personalized, and flexible instruction in response to growing learner demand. Although English is widely taught in Brazilian schools, persistent structural constraints often limit students’ development of communicative proficiency, prompting some learners to seek instruction from independent …


Domain-Specific Fine-Tuning Of Neural Machine Translation For Georgian Religious Texts, Jacob Brent Fisher Apr 2026

Domain-Specific Fine-Tuning Of Neural Machine Translation For Georgian Religious Texts, Jacob Brent Fisher

Theses and Dissertations

This thesis investigates whether domain-specific fine-tuning of a large multilingual neural machine translation model improves translation quality for English-to-Georgian religious text, a low-resource pair underserved by existing systems. Using the 1.3-billion-parameter NLLB-200 model as a baseline, two LoRA-adapted variants were trained: General-FT, on 91,143 parallel segments of contemporary religious discourse drawn from the General Conference talks and other publications of The Church of Jesus Christ of Latter-day Saints, and Scriptural-FT, on 33,229 segments from the scriptural canon of The Church. The three models were evaluated using automated metrics (BLEU, chrF, COMET) covering both domain-matched and cross-domain conditions, and on a …

The Lookahead Transformer, Justin P. Olcott Apr 2026

The Lookahead Transformer, Justin P. Olcott

Theses and Dissertations

Large Language Models (LLMs) are transformer models that generate text autoregressively in two stages: prefill and decode. The prefill stage processes all input tokens in parallel and caches them into the KV cache. The decode stage uses the KV cache, processes a single token at a time, and is generally memory-bandwidth constrained. Each decode step generates a token probability distribution, samples from it, appends the token to the cache, and repeats. This left-to-right, one-at-a-time generation paradigm has proven effective for language modeling in many domains; however, it also has limitations such as token permanence, constant compute per token generation, constant …


Model Unification: A Systematic Approach For The Cluster Expansion, Kolten Barfuss Apr 2026

Model Unification: A Systematic Approach For The Cluster Expansion, Kolten Barfuss

Theses and Dissertations

A systematic approach for model unification of cluster expansion models is developed and demonstrated. The method builds on previous work with the Manifold Boundary Approximation Method (MBAM) to identify supremal models. The work is motivated by the exercise of unifying cluster expansion models – characterized by Π matrices – for two binary alloys that share one atomic species to form a model for the ternary alloy. The result is the Supremal Π Algorithm, a systematic unification algorithm that relies on an MBAM-informed understanding of models and on the singular value decomposition. The algorithm yields ΠΛ, a Π matrix for the …


The Artificial Maintenance Of Relationship Satisfaction: Romantic Ai Companion Usage Sustains Emerging Adults' Human Romantic Relationship Satisfaction While Eroding Relationship Stability, Rebekah M. Hakala Apr 2026

The Artificial Maintenance Of Relationship Satisfaction: Romantic Ai Companion Usage Sustains Emerging Adults' Human Romantic Relationship Satisfaction While Eroding Relationship Stability, Rebekah M. Hakala

Theses and Dissertations

As artificial intelligence becomes increasingly sophisticated, romantic AI companions--AI systems designed to simulate romantic, emotional, or sexual relationships--have emerged as a novel relational phenomenon. Nearly one in four emerging adults now engage with romantic AI companions, yet little is known about how this usage affects their romantic human relationships. Drawing on Social Exchange Theory and the Investment Model of Commitment, and employing structural equation modeling, this thesis uses data from 2,431 emerging adults in romantic relationships to examine whether romantic AI companion usage influences relationship satisfaction and relationship stability among emerging adults in the United States (ages 18-30), and whether …


More Than Treating Errors: Bridging The Gaps And Expanding The Agenda For Scholarship On Teacher Written Feedback For L2 Writers, Lynn Goldstein, Robert Kohls Apr 2026

More Than Treating Errors: Bridging The Gaps And Expanding The Agenda For Scholarship On Teacher Written Feedback For L2 Writers, Lynn Goldstein, Robert Kohls

Journal of Response to Writing

Teacher written feedback is a central area of L2 scholarship and writing teacher education yet considerable research has focused on written corrective feedback (WCF) with considerably less attention paid to discourse-level (DLF) teacher written feedback. Our article identifies the gaps in the current teacher written feedback scholarship, explains why these gaps are problematic, and provides detailed recommendations for an agenda that examines teacher DLF and students’ use of this feedback. Our goal is to encourage scholars to explore new avenues of research that better take into account what writing “is” and “does” as well as take into account the linguistically …


Composing In Relation: Rethinking Multimodal Feedback As Rhetorical Design, Angela Laflen Apr 2026

Composing In Relation: Rethinking Multimodal Feedback As Rhetorical Design, Angela Laflen

Journal of Response to Writing

This qualitative study investigates how writing instructors compose feedback in multimodal digital environments, focusing on the rhetorical and relational dimensions of their design choices. Drawing on social semiotics and multimodal composition theory, the study analyzes feedback artifacts, instructor interviews, and student surveys from six first-year writing courses. Findings reveal that instructors engage in complex feedback design work across communication modes, often without formal training or shared frameworks. Instructors tended to default to text-based habits shaped by genre memory but adapted their strategies in response to communicative breakdowns and student needs. The study identifies three core themes: reliance on print-era conventions, …


Examining Automated Writing Evaluation Error Coverage In Relation To Uptake And Retention, Mohaddeseh Mehrzad, Mohammad Rahimi, Stephanie Link Apr 2026

Examining Automated Writing Evaluation Error Coverage In Relation To Uptake And Retention, Mohaddeseh Mehrzad, Mohammad Rahimi, Stephanie Link

Journal of Response to Writing

Despite the current widespread use of Automated Writing Evaluation (AWE) feedback, many issues regarding its efficacy still remain unresolved. Recent studies mainly focus on correctly detected errors with a lack of attention on the comprehensiveness of error detection, or error coverage. Error coverage is interesting because little is known about the capacity of AWE systems to fully detect common second language (L2) errors. It is also important to investigate the potential effect of such capacity on student uptake and retention, which are important constructs in fostering L2 writing development. To this end, the present study compared teacher feedback and AWE …


Navigating Feedback In Collaborative Writing: The Impact Of Student Backgrounds And Expectations On Transitions To New Academic And Social Spaces, Lindsey Gruber, María Fernández–Agüero Apr 2026

Navigating Feedback In Collaborative Writing: The Impact Of Student Backgrounds And Expectations On Transitions To New Academic And Social Spaces, Lindsey Gruber, María Fernández–Agüero

Journal of Response to Writing

This article examines how international students navigate feedback from a supervisor while working on a group writing project in a diverse English medium of instruction (EMI) bachelor’s program at a public university in Denmark, where no formalized writing or language support resources are offered in the students’ first year of instruction. Data were collected in qualitative, semi-structured interviews with 11 students who were identified through a survey of a first-year bachelor of arts cohort. Results from the survey showed that despite using a supervision model of education, few students perceived changes in feedback compared to their secondary school experiences, and …

Drawing on focus group interviews and systematic observations, the study centered students’ movement, vocal expression, rhythmic participation, and peer interaction as …


Shame On You! The Socialization Of Self-Conscious Emotions In Early Childhood, Ashton K. Allen Apr 2026

Shame On You! The Socialization Of Self-Conscious Emotions In Early Childhood, Ashton K. Allen

Theses and Dissertations

This study examined how parents and children discuss self-conscious emotions across early childhood. Self-conscious emotions such as shame, guilt, embarrassment, awe, and pride play a critical role in children's social and emotional development. Although prior research has demonstrated links between parent and child emotion talk about basic emotions such as happiness, anger, disgust, fear, sadness, less is known about how parents and children talk about self-conscious emotions. Participants for the current study were 247 parent-child dyads. The dyads completed a wordless storybook task designed to elicit discussion of five self-conscious emotions (shame, guilt, embarrassment, awe, and pride) annually across three …
