Panda-Plus-Bench: A Clinical Benchmark For Evaluating The Robustness Of Ai Foundation Models In Prostate Cancer Diagnosis, Joshua L. Ebbert, Dennis Della Corte

Faculty Publications

Artificial intelligence foundation models are increasingly deployed for prostate cancer Gleason grading, where GP3/GP4 distinction directly impacts treatment decisions (active surveillance vs. intervention). However, these models may achieve high validation accuracy by learning specimen-specific artifacts rather than generalizable biological features, limiting real-world clinical utility. We introduce PANDA-PLUS-Bench, a curated benchmark dataset derived from expertly annotated prostate biopsies designed specifically to quantify this failure mode. The benchmark comprises nine carefully selected whole slide images from nine unique patients containing diverse Gleason patterns, with non-overlapping tissue patches extracted at both 512 × 512 and 224 × 224-pixel resolutions across eight augmentation conditions. …

Same-Subject Induction Experiences For Elementary Music Teachers: Teacher Efficacy Beliefs, Experiences Of Isolation, And Job Satisfaction, Wendy Tams Hickman

Theses and Dissertations

This survey study seeks to explain the relationships between elementary music teachers' experiences with same-subject induction support and those teachers' feelings of teacher efficacy, experiences of isolation, and job satisfaction. Independent variables came from latent class groupings of same-subject induction support for beginning elementary music teachers. Teacher background variables were also included as controls. Three- and four-step regression models helped provide understanding about how the relative set of predictors--teacher background variables, isolation levels, induction experiences, and interaction terms--predicted the three outcomes. Initial regression analyses showed that the number of years of teaching elementary music predicted efficacy and levels of isolation …

An Informationally Novel Sense Of Triviality For Harman’S Clutter Principle, Joseph D. Rasmussen

Undergraduate Honors Theses

Gilbert Harman (1986) argues that we ought not believe some logical consequences of our beliefs. To do this, he uses the Clutter Principle—that we should not clutter our minds with trivialities—and claims that some logical consequences are in some sense trivial. I show that interpreting Harman’s argument using an interest-driven sense of triviality (e.g. what Friedman calls junk) conflicts with a plausible epistemic norm. In light of this, epistemologists have turned the Clutter Principle into a norm on inquiry. This, however, loses the strength of the Clutter Principle in Harman’s argument. In this paper, I provide an alternate sense of …

The Correlation Between Perceptual Abilities And The Acquisition Of Non-Native Consonant Clusters, Hope Emma Nielson

Theses and Dissertations

A common approach in the study of speech motor learning is to have speakers learn to produce clusters of consonants that do not occur in their native language. This study investigated the relationship between auditory or speech perceptual abilities and the initial acquisition of non-native stop-stop consonant clusters. Sixty young adult participants (56 female, four male) were administered a gap detection test and a speech-in-noise test to assess their innate perceptual skills. The participants then performed a nonsense-word repetition task featuring non-native consonant clusters in the initial position. The participants' spoken productions of the nonwords were recorded and analyzed acoustically …

The Effects Of Phonetic Knowledge And Bilingualism On The Acquisition Of Non-Native Consonant Clusters, Kylie Wakley

Theses and Dissertations

Speech motor learning involves the production of new sounds or sound sequences. This study investigated how explicit phonetic knowledge and bilingualism affect how individuals acquire sound sequences that do not occur in English, or non-native consonant clusters. Sixty adults with typical speech, aged between 18 and 27 years, participated in the experiment. The researcher recruited participants into four groups based on their phonetic background (experienced or not) and language background (monolingual, bilingual). The participants produced stop-stop and fricative-nasal clusters in the initial position of nonsense words across six practice blocks. The duration of each cluster was measured, which in English …

Unlocking The Colleague Next Door, Yoshihiko Ariizumi

Learning, Teaching, & Researching Optimization

The structural barriers that isolate faculty from one another—individualistic reward systems, professional identity protection, disciplinary silos, fragmented time—have been documented in detail elsewhere. This paper begins where that analysis ends. Its sole focus is solutions: what actually works, what you can do without waiting for your institution to change, and most importantly, what you can do today. It is organized in three movements: evidence-based institutional strategies, community-level structures any group of faculty can build, and a granular map of the smallest possible individual first steps—the ones that cost almost nothing and have an outsized probability of changing how you experience …

Functional And Structural Lesion Network Mapping: Insights Into Acquired Brain Injury And Insomnia, Kathleen Erekson Rugh

Theses and Dissertations

Insomnia disorder is the most reported sleep disorder and can negatively affect daily functioning. Acquired brain injuries can lead to insomnia disorder. Limited research has explored a causal link between brain networks and insomnia symptoms in this population. This study replicated a lesion network mapping methodology of an insomnia study (Helquist et al., 2024) and extended it to examine structural networks linked to insomnia symptoms in individuals with acquired brain injuries. Traced lesions (N =44) were used as seed regions to compare against normative functional and structural network data. For functional analyses, we used resting state fMRI scans from a …

Baseline Moderators Of A Transdiagnostic Adolescent Sleep And Circadian Health Intervention's Effectiveness At Improving Circadian Sleep Health: A Pilot Investigation, Jamon M. Jex

Theses and Dissertations

The current study examined whether baseline demographic and clinical characteristics moderate the effectiveness of the Transdiagnostic Sleep and Circadian (TSC) intervention in improving adolescent circadian sleep health. Using an integrative data analysis approach, data from three independent adolescent samples (N = 134; ages 10-18) were pooled to evaluate changes across multidimensional sleep outcomes defined by the RU-SATED model of sleep, including regularity, satisfaction, alertness, timing, efficiency, and duration. Linear mixed-effects models were used to assess pre-to-post intervention changes and test moderation by age, sex, family income, and clinical status. Results indicated significant improvements in sleep satisfaction following TSC, with greater …

Real-Time Instruction Internalization For Large Language Models, Brenden Smith

Theses and Dissertations

For the end user, Large Language Models (LLMs) are programs that process natural language inputs into natural language outputs. In popular usage, this tends to take the form of conversation: a user asks a question, provides information, or gives instructions, and the LLM (hopefully) replies in a manner we would expect of an informed and compliant person. While convenient and intuitive for users, this natural conversational format encourages the misconception that LLMs are learning from conversations, when they do not. This work presents the benefits and practicality of a language model paradigm that meets this user expectation -- that is, …

Beyond Pedagogical Inertia: Understanding And Overcoming The Barriers To Effective Faculty Work In Higher Education, Yoshihiko Ariizumi

Learning, Teaching, & Researching Optimization

Academic faculty are among the most educated professionals in the world. Yet a striking body of empirical research demonstrates that they face profound, systematic barriers to performing their own work effectively—barriers that are cognitive, institutional, cultural, and structural in origin. This paper extends the analysis of “pedagogical inertia” beyond the classroom to the full scope of faculty professional life: research, writing, service, advising, and self-directed learning. Drawing on evidence from organizational psychology, cognitive neuroscience, higher education research, and behavioral science, we identify six classes of barriers that consistently impede effective faculty work, and we analyze—with reference to documented successful cases—the …

Neuroscience-Based Intellectual Productivity: A Ten-Principle Methodology For Knowledge Workers, Yoshihiko Ariizumi

Learning, Teaching, & Researching Optimization

This paper presents a comprehensive, neuroscience-grounded methodology for enhancing intellectual productivity among knowledge workers—particularly academic faculty and researchers operating under conditions of chronic cognitive overload. Drawing on ten foundational principles derived from contemporary cognitive neuroscience, we argue that substantial gains in research output, creative ideation, and knowledge integration are achievable not by working harder, but by working in deliberate alignment with the brain’s native computational architecture.

The ten principles address: strategic activation of the Default Mode Network (DMN) for incubation and creative insight; prefrontal cortex (PFC) energy management through temporal task separation; externalization of cognitive load via AI-assisted working memory …

Pioneering Change: Digital Reformatting For Sustainable Av Stewardship, Cory Nimer, Ben Harry, Abby Beazer, Miya Jensen, Michael Gates, Karen Glenn

Faculty Publications

Archives and libraries face growing preservation challenges from aging audiovisual collections due to carrier degradation and playback equipment obsolescence. As the media becomes more difficult to access, its archival value decreases, leading to questions about its ongoing storage. One proposed solution has been to digitize and discard the original media, preserving the recordings as digital masters with derivative files for public access. The suggestion to reformat audiovisual materials raises questions for cultural heritage professionals, and each stakeholder group may have its own concerns. Yet as media capture and digital preservation technology improve, to maintain our program's sustainability, we have begun …

Engagement Modeling And Inference For Risk-Aware Path Planning Under Adversarial Uncertainty, Grant Stagg

Theses and Dissertations

This dissertation develops methods for planning safe and efficient trajectories for autonomous vehicles operating in environments containing adversarial and environmental threats with uncertain parameters. The central objective is to quantify and control the risk of adverse events--such as interception or detection--when threat characteristics are imperfectly known. To address this challenge, probabilistic weapon engagement zone (PEZ) models are introduced to estimate the likelihood of violating adversarial engagement constraints under uncertainty in pursuer state and capabilities. Multiple computational strategies are developed for PEZ evaluation, including first-order sensitivity-based approximations, Monte Carlo estimation, and neural-network surrogate models. These approaches enable rapid engagement-probability assessment and …

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.

A Comparative Study Of Tin Electrorefining In Molten Licl–Kcl–Cacl₂: Experimental Two-Electrode Current Control And Theoretical Three-Electrode Potential Control, Bryant Johnson, George Ankrah, Ander Fuller, Devin Rappleye

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

Molten salt electrorefining is a mature technology for metal recovery, yet conventional current‑controlled, two‑electrode operation provides limited electrochemical selectivity and restricted insight into electrode‑specific behavior. In this work, a simplified model is developed to compare current‑controlled two‑electrode electrorefining data with a potential‑controlled three‑electrode electrorefining simulation using tin in molten LiCl–KCl–CaCl₂ as a surrogate for plutonium processing. The model examines anodic and cathodic limitations under fixed‑potential operation and evaluates implications for selectivity, efficiency, and runtime relative to experimentally demonstrated two‑electrode performance. Results indicate that independent potential control enables operation closer to thermodynamic selectivity limits, with the potential to suppress impurity oxidation …

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.

Motivation Vs. Negative Feelings Among Individuals With Autism Spectrum Disorder And Social Anxiety​, Jakob Carver, Eden Ordyna

FHSS Mentored Research Conference

This study examines how motivation relates to negative emotional experiences across three groups: individuals with autism, individuals with social anxiety, and a control group. As shown in Figure 1, higher motivation is associated with lower levels of negative feelings across all groups, indicating a consistent inverse relationship.

Baseline differences are evident, with individuals with social anxiety reporting the highest negative feelings, followed by those with autism, and the control group reporting the lowest. While all groups show similar downward trends as motivation increases, the reduction appears most pronounced in the control group. In contrast, individuals with autism and social anxiety …

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 …

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

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.
