Design And Simulation Of Anti-Resonant Hollow-Core Fiber For Sensing Applications, Pravallika Kante

Theses and Dissertations

This thesis presents the design and simulation of an 8-tube single-ring anti-resonant hollow-core fiber for sensing applications, with particular emphasis on methane gas detection at the fundamental absorption wavelength of 3.3 µm. Conventional solid-core silica optical fibers exhibit strong multi-phonon material absorption beyond 2.5 µm, rendering them fundamentally unsuitable for efficient light guidance and direct gas sensing at mid-infrared wavelengths. Anti-resonant hollow-core fibers overcome this limitation by guiding light predominantly through an air-filled hollow core via the anti-resonant reflecting optical waveguide mechanism, in which the thin silica glass walls of the cladding tubes act as Fabry-Pérot etalons that confine the …

Unlocking Innovation: The Impact Of Psychological Safety, Organizational Structure, And Rigidity On The Pursuit Of Innovation Within The Firm, Robert Kyle Rudd

Theses and Dissertations

Innovation is often a competitive advantage generator, growth, and organizational success. However, there is relatively little empirical literature that describes how organizations may be designed such that employees also feel significant freedom to innovate. This dissertation investigates the role of psychological safety and organizational design conditions, perceived organizational structure and perceived organizational rigidity as joint predictors of perceived freedom to innovate (PFTI) of employees.

The quantitative, cross-sectional survey design was used to gather data of 425 full-time U.S.-based employees who were recruited through CloudResearch. Respondents undertook validated scales of psychological safety, perceived organizational structure, perceived organizational rigidity and perceived freedom …

Hybrid Machine Learning For Zero-Day Malware Detection: An Adaptive Static-Dynamic Analysis Approach, Garrett Farmer

Theses and Dissertations

In an era of swiftly evolving cyber threats, zero-day malware continues to be one of the most challenging classes of attacks to detect and mitigate.

Host Families’ Perspectives Of The Impact Of The Commodification Of Education On The Student-Host Family Relationship In Study Abroad, Guadalupe Bustamante

Dissertations

The growing commodification of education has reshaped study abroad in ways that extend beyond marketing and program design. While homestays have traditionally been viewed as the ideal format for cultural immersion and language acquisition, research has largely overlooked how these trends affect the student-host family relationship from the family's perspective.

This study examines whether, and, if so, how Spanish host families perceive their roles and relationships with the American students they host have been impacted by these trends. Using a qualitative exploratory case study design, the research focused on representatives from eight families in Madrid, who have hosted U.S. students …

Agents Of Agency: Identifying Teacher Traits And Trainings Associated With Promoting Student Agency, Clara Mateo

Dissertations

This study shifts the focus of mathematics teacher quality from the traditional metric of test scores to “student agency,” defined as a learner's capacity to access power, make decisions, and take ownership of their learning process. While the literature on student agency provides ample qualitative insights, it is largely composed of small-scale studies. This research addresses this gap by conducting a large-scale, nationwide quantitative analysis to identify teacher factors associated with the promotion of student agency. The central research question is: What teacher demographics, dispositions, and professional development experiences are associated with increased student agency?

This study used a cross-sectional …

The samples were found to have higher median P-wave values than those determined by Rudnick and Fountain (1995; 7.4 km/s to 7.8 km/s, as compared to 6.9 km/s to 7.2 km/s). This indicates both a …

Martha Mitchell: Loud Mouth Of The South, Emma Bernice Kolker

History Undergraduate Honors Theses

In this paper, I will argue how Martha‘s Arkansas identity presents itself as a double edge sword, with her personality attracting the attention of the public with the consent of powerful men in the Republican party, while at the same time her comments and actions were the very reason she was blamed and marginalized by the same men who allowed her to speak in the first place.

Romulus As A Rhetorical And Historiographical Tool In Imperial Roman Literature, Jaden M. Perry

History Undergraduate Honors Theses

This study exames the figure of Romulus in imperial Roman literaure as neither a fixed mythological nor historical subject, but as a flexible rhetorical and historiographical tool. Surveying a range of authors from the late first to fourth centuries CE, inlcuding historians such as Florus, Tacitus, Justin, Suetonius, and the Historia Augusta, as well as literary authors like Juvenal, Silius Italicus, Valerius Maximus, and Seneca, the thesis argues that references to Romulus and his deified counterpart Quirinus are deliberately manipulated to serve distinct authorial purposes. Rather than merely recounting Rome’s foundational myth, these writers employ Romulus to construct comparisons, …

A "Felon" In The White House: A Study Of The 2024 Election And The Racialized Violence Of The Word "Felon" In American Politics, Val Arnold

FCRH Honors Program Theses

One of the campaign strategies pursued by the Democratic Party in the 2024 presidential election was the use of a felon-centered discourse when discussing Donald Trump. Through the use of such discursive strategies, the Democratic Party attempted to evoke the sense of fear typically associated with discussions of crime, hoping to make voters associate the “fear” with Trump, a white man. In the media, the language used in speeches and advertising campaigns serves as a powerful tool. The current literature discusses how language operates as a “representational system,” and ultimately, words serve to give meaning. Although many articles separately discuss …

The Impact Of Glucose Exposure On Organic Cation Transporters (Oct) Function In A Corneal Epithelial Cell Line, David A. Garza

Theses & Dissertations

Organic cation transporters (OCT) facilitate the movement of neurochemicals and medications, contribute to the removal of cellular waste, and facilitate neuronal communication. Three subtypes of these high-capacity, low-affinity transporters (OCT1, OCT2, and OCT3) are differently expressed in peripheral tissues such as the liver, kidneys, as well as the central nervous system. OCTs are also expressed in ocular tissues. Chronic hyperglycemia is a complication commonly associated with diabetes that can lead to ocular diseases such as diabetic keratopathy, which affects the cornea. In this project, we expose immortalized human corneal epithelial cells (HCE-S) to various glucose concentrations to study their impact …

Moderating Effects Of Defense Mechanisms On The Link Between Dark Triad Traits And Stress: A Replication With Addition Of Early Trauma, Ngayin Cheng

Student Theses

Literature suggested Dark Triad traits, comprised of narcissism, Machiavellianism, and psychopathy, are linked to adverse childhood environment and maladaptive coping that contribute to negative mental health outcomes, but Richardson and Boag's study (Richardson & Boag, 2016) was one of the few studies that first found Dark Triad traits are associated with immature defenses and higher perceived stress simultaneously. This replicated study aims to verify the original findings of their research by examining how defense mechanisms moderate the relationship between Dark Triad traits and perceived stress. A sample of 199 participants completed self-report measures assessing the Dark Triad traits, defense styles, …

A Meta-Analysis On Joinder Effects: Do They All Have The Same Magnitude?, Amelia M. Tisk

Student Theses

The present meta-analysis examined whether different forms of joinder and procedural consolidation produce varying levels of prejudice in adjudicative decision-making. Although joinder procedures improve judicial efficiency, psychological research has suggested that combining charges, defendants, or plaintiffs within a single proceeding may increase conviction likelihood, liability judgments, and broader perceptions of wrongdoing. A random-effects meta-analysis was conducted across 22 independent study effects examining charge joinder, defendant consolidation, plaintiff consolidation, multiple-complainant procedures, and related aggregation paradigms. Effect sizes were converted to Pearson’s r whenever possible. Overall, procedural aggregation produced a moderate effect on adjudicative outcomes, r = .27, 95% CI [.22, .32]. …
