Human Performance In Context: Exploring The Effect Of Social Support On Vigilance, Allison E. Garibaldi

Graduate Thesis and Dissertation 2023-2024

Over many decades, vigilance research has consistently found that performance on vigilance tasks decline over time (i.e., the vigilance decrement; Davies & Parasuraman, 1982), and that performing a vigilance task is both mentally demanding and stressful (Warm et al., 2008). Researchers have subsequently implemented a wide range of interventions to both understand and attempt to attenuate the vigilance decrement and its associated affective effects. Among these efforts, little attention has been devoted to understanding the effects of the social environment on vigilance. Nonetheless, a handful of studies have indeed suggested that the presence of others can affect performance, workload, and …

High-Order Harmonic Generation In Bulk And Thin Film Solids, Troie Journigan

Graduate Thesis and Dissertation 2023-2024

High-order harmonic generation (HHG), a non-perturbative nonlinear light-matter interaction resulting in coherent emission of high-frequency light, has demonstrated promise as an optical probe of carrier dynamics, structural symmetries, and other properties of solids. HHG from bulk solids in transmission geometry, however, is influenced by nonlinear propagation of the driving laser, which leads to spectral skewing and temporal phase variations in the harmonic emission. These effects obscure the microscopic underlying physics, making HHG-based spectroscopy of bulk solids difficult to interpret. HHG in few-to mono-layer materials, however, avoids strong nonlinear propagation effects, and can provide novel material properties for HHG studies.

Exploring The Physiology Of Clostridioides Difficile: Selenium-Dependent Catabolism Of Host-Derived Nutrients, Michael A. Johnstone

Graduate Thesis and Dissertation 2023-2024

Clostridioides difficile is a bacterial pathogen that causes pseudomembranous colitis and the majority of antibiotic-associated diarrheal cases. Broad-spectrum antibiotic usage disrupts the normal gut microbiota and thereby compromises colonization resistance, the main defense against C. difficile infection. Treatment options are limited to vancomycin, fidaxomicin, and the fecal microbiota transplant. Addressing the scarcity of these therapeutics, we documented two explorations in C. difficile drug discovery: (i) evaluation of antibacterial and toxin-suppressing activity of (+)-puupehenone and similar derivatives, and (ii) clarification of a discrepancy in the hypothesized mechanism of auranofin against C. difficile. A better understanding of how C. difficile colonizes …

Measuring Elementary Students' Level Of Acquisition Of Historical Habits Of Mind, Natalia E. Cruz

Honors Undergraduate Theses

Providing elementary-aged students with opportunities to engage in authentic historical analysis is crucial to building their historical thinking skills. Teaching with primary and secondary sources allows students the opportunity to engage in authentic inquiry-based learning experiences where the acquisition of a historical concept is in their hands. This differs from the traditional social studies learning experience, as these inquiry-based learning experiences are student-centered, and the teacher is present as a guide. Developing social studies instruction utilizing the SOURCES Framework for Teaching with Primary and Secondary Sources (Waring, 2021) is an effective way to scaffold authentic historical inquiry at the upper …

Metaontological Dismissive Strategies: Implications And Applications In Metaphysics Of Race And Gender, Ethan F. Stumpp

Honors Undergraduate Theses

Metaontological discourse, inquiring into the nature, methodology, and aims of ontology, has functioned as the war ground for those skeptical of ontological projects against those who believe that ontological inquiry is substantive (i.e., meaningful, important, worth pursuing). I call the inquiry which engages in determining criteria to distinguish substantive from nonsubstantive inquiry/discourse: “the metaphysics of discourse”. In this project, I identify three frameworks in the metaphysics of discourse: Easy Ontology, The “Merely Verbal” Framework, and Metaphysical Structuralism. My primary concern is to show that these discourse frameworks or dismissive strategies all fail to provide sufficient criteria to properly delineate substantive …

Relationship Between Fentanyl Misinformation And College Students' Intentions To Administer Naloxone, Zoe Ryon

Honors Undergraduate Theses

Background: The news media has spread misinformation about the toxicity and potency of fentanyl, exaggerating the extent to which bystanders could be harmed by fentanyl when responding to overdose situations. College students are increasingly among the victims of opioid overdose, and their peers may be the nearest person capable of administering naloxone – an overdose reversal medication. However, college students who fear incidental exposure to fentanyl may be worried about administering naloxone.

Design Modifications To Reduce A Brushless Exciter Response Time, Esnick Felissaint

Graduate Thesis and Dissertation post-2024

As an alternative to converting a brushless exciter to static excitation in order to improve an exciter’s response time, conversion of the existing conventional brushless exciter is possible. A high initial response (HIR) brushless excitation system has the ability to force its output to ceiling voltage in 0.1 second or less, which is a response time similar to a static excitation system. To achieve the required fast response time, various modifications to the existing exciter components are required, including the ac exciter stator, permanent magnet generator (PMG), and voltage regulator. This paper describes those required modifications and associated technical information. …

Design Parameters For A Piezoelectric-Based, High-Authority, High-Bandwidth Flow Injection Valve, Sydney A. Giannuzzi

Graduate Thesis and Dissertation post-2024

Aeromechanical Identification Methodology (AIM) is an approach to measure damping in turbomachinery to identify and map flutter boundaries across various operating conditions. Previous approaches required entering, or nearly entering, flutter to produce a binary “flutter” / “no-flutter” boundary. AIM is significantly safer; however, it is limited by actuation authority and bandwidth. A non-contact, high-frequency, high-amplitude piezoelectric-based valve provides a promising solution to bridge these gaps. This valve operates by ejecting high-frequency oscillatory flow from a piezoelectric-based converging nozzle as a non-contact method of imparting a harmonic force. This valve has broad applications for high-frequency flow modulation beyond the motivating structural …
