Proclaiming The Suppressed Truth: Romans 1:16-25, Michael D. Royster

Sermon Studies

When Paul wrote about “suppressing the truth,” he remembered the tactics used on those who proclaimed the Word of God. Before Paul’s conversion, he approved of Stephen’s public execution by stoning. After Paul’s conversion, he on more than one occasion fled the scene to escape persecution and attempted murder. Like Stephen, Paul became a proclaimer of the truth and faced an imminent threat of violence to further suppress his message. There exist possible homiletical directions the preacher may take and a range of collective illustrations that can bridge the ancient with the modern world concerning matters of the heart and …

Towards Designing And Performing Biological Sex: Explorations Of The Cyborg And The Inanimate, Beja Puskas

Theatre and Dance Honors Projects

While gender has been largely debunked as a form of performance, biological sex remains an irreducible point of departure. This essay challenges biological sex as a category through the Foucauldian lens of bio-power and technologies of the self. It merges findings from interviews surrounding intersectionally marginalized experiences with menstruation with trans and disability studies. Utilizing Mel Chen’s theory of animacies, and Margrit Shildrick’s human-technology amalgamation theory, this essay blurs the biological-artificial binary. While there are obstacles, limiting what is biologically possible for humans, the body can be significantly augmented through imagination, body modification, and the invention of newly gendered practices.

Grounding Dependency Within Case Study Of Tourism In Cuba, Abby Mccarroll

Sociology Honors Projects

The research investigates the tourism industry in Cuba as a case study for dependency theory as articulated by Milton Santos’s Toward an Other Globalization. The research examines interactions between tourists and locals, and how Cubans navigate the contradictions of a socialist project embedded in a capitalist economy. Through an analytical macrosociological lens, the research contributes to wider considerations of dependency, economic sovereignty, and the uneven impacts of globalization. I argue that the case study of tourism in Cuba expands Santos’ theories to demonstrate how a country that refutes neoliberal ideology still finds itself trapped within the dynamic of dependency.

Unboxing Relations: An Ethnographic Study Of Blind Box Consumption In The U.S., Wendy Zheng

Sociology Honors Projects

Blind box consumption is a format for purchasing packaged toys without knowing the specific item in advance. It has become a global trend and is often viewed as irrational or gambling-like behavior in past literature. Drawing on ethnographic observations and interviews conducted in retail settings, this study examines how consumers make sense of uncertainty through social interaction. This study proposes a two-layer model of consumption. In the first layer, social interaction during the consumption process helps consumers negotiate risk, generate meaning, and become more skilled buyers. In the second layer, consumers engage in moral and value judgments that involve distancing …

Artemis Cubesats Help Advance Exploration Of The Moon, Mars, And Beyond, Russell Lane, David Beaman, Courtney Ryals, David Hitt

Small Satellite Conference

On April 1, NASA launched the Artemis II mission – the first crewed mission of the Artemis campaign. The nine-day lunar flyby launched on the agency’s SLS (Space Launch System) rocket and had four astronauts test the Orion spacecraft in high Earth orbit and in deep space. Four 12U CubeSats also launched on the mission, housed within the SLS’s Orion stage adapter (OSA). The spacecraft were deployed approximately five-and-a-half hours into the flight, following Orion separation and departure from SLS, as the SLS interim cryogenic propulsion stage (ICPS) and the attached OSA were in a high Earth orbit on an …

Recursive Artificial Intelligence Training And The Homogenization Of Discourse, Sam Hemesath

Political Science Honors Projects

As Large Language Models (LLMs) begin to produce text on the internet, the same repository from which training data for LLMs are scraped, LLMs will start to train on data they produced. What will happen to future models when LLMs are trained on their own text? Scholars have raised concerns about the possibility that LLMs homogenize language and discourse. These concerns are further exaggerated as LLMs begin to infect their own repositories, marking a turn from human-produced training data sets. In this paper I simulate a recursive training loop by prompting a popular open-source LLM with 1000 prompts and using …

Esa Scout Hydrognss Early Mission Results, Martin Unwin, Alex Da Silva Curiel, Ben Stern, Jean-Pascal Lejault, Nazzareno Pierdicca

Small Satellite Conference

The ESA Scout HydroGNSS mission demonstrates a new generation of GNSS reflectometry (GNSS R) capabilities for hydrological climate monitoring from small satellites. HydroGNSS measures soil moisture, freeze–thaw state, inundation, wetlands and above ground biomass by exploiting both traditional incoherent Delay Doppler Maps (DDMs) and several innovative signal types not previously available from spaceborne GNSS R missions. Early in orbit results confirm successful acquisition of signals from Galileo, dual polarisation measurements, coherent complex channel data and reflections at the second GNSS frequency (L5/E5a). These enhanced measurements exhibit stronger than predicted performance and are expected to significantly improve retrievals of climate relevant …

Melodizing Modern Power: Giacomo Puccini And The Demands Of Thematic Development, Claire Kelly

Music Honors Projects

This paper examines Italian composer Giacomo Puccini’s processes of thematic development in three operas, La Bohème (1896), Tosca (1900), and Il Tabarro (1918). Puccini’s thematic development has been a point of contention for many musicologists and critics. Critics of his own time found his thematic development style to be inconsistent; some regarded his melodies as fragmented and lacking cohesion. Since then, biographers and critics such as Michele Girardi, Mosco Carner, and Alexandra Wilson have reiterated and re-examined these claims. Taken together, my three case studies conclude that Puccini’s multivalent style of thematic development is meant to depict the various effects …

Adaptive Rational Approximation In Dynamic Economic Models: A Novel Application Of The Aaa Algorithm To Economic Growth, Adaye Sosthene Yvan N'Guettia

Mathematics, Statistics, and Computer Science Honors Projects

I study adaptive rational approximation for fixed points that arise in infinite-horizon dynamic programming. I integrate the Adaptive Antoulas–Anderson (AAA) algorithm into Bellman- and Euler-based fixed-point solvers by recomputing a barycentric rational interpolant at each update. In addition to standard AAA, which selects support points from interpolation residuals, I study a residual-weighted variant in which Bellman,Euler, or KKT diagnostics act as secondary weights on the greedy pivot rule. This alignment of approximation adaptivity with the underlying equilibrium conditions can concentrate degrees of freedom in regions of steep curvature, sharp transitions in localbehavior, and other localized features that typically degrade polynomial …

An Analysis Of The Effects And Implementations Of The Early Literacy Grant In Arizona, Alicia Severiano Perez

Mathematics, Statistics, and Computer Science Honors Projects

Over the years, states have implemented Science of Reading (SoR) frameworks to address low literacy levels. The Early Literacy Grant (ELG) in Arizona funds and supports such frameworks for schools serving low-income students. This paper is the first to explore the grant through interrupted time series modeling to evaluate effectiveness and text analysis to understand its implementation. We do not find clear evidence of positive effects caused by the grant, other than some cases, such as Yuma County. Schools typically allocate funds toward salaries and hiring instructors. These findings raise questions about whether its allocations should be closely monitored.

Level Sets For Lehmer Codes Of Pattern Avoiding Permutations, Avery Sinclair

Mathematics, Statistics, and Computer Science Honors Projects

We study the poset structures for two families of pattern avoiding permutations. An n-permutation is a list of the numbers [n]={1,2,...,n}. A permutation is 321-avoiding when it does not contain a decreasing subsequence of length 3. A poset (partially ordered set) is a set such that some elements can be compared with one another. Using Lehmer codes, we define a poset for 321-avoiding permutations. We then fully describe the six lowest levels of this poset. We then consider the analogous poset for 123-avoiding permutations (which don't contain an increasing subsequence of length 3) and fully describe the three lowest levels.

Unsustainable Stories: Agricultural Knowledge On The Great Plains, 1880-1934, Philomena Shuffelton-Sobe

History Honors Projects

This thesis explores stories about how people farmed and learned about farming on the Great Plains from 1880-1920 through three inter-connected narratives: the Allotment system, agricultural education programs at federal Indian Boarding Schools, and the rapid rise and fall of the Dry Farming movement. These systems were built on stories about how people should live with and on the land that promoted unsustainable, destructive ways of farming and knowledge production. This scholarship places Assimilation Era agricultural education for Native and non-Native farmers within the context of the increasing reliance on systems and science and the institutionalization of agricultural knowledge.

Effects Of Bx795, Gsk8612, And Mrt67307 On Mouse And Human Ovarian Cancer Cell Lines, Shuhd Waleed Al Noumani

Student Research and Creative Activity Expo

Ovarian cancer (OC) is the deadliest gynecologic malignancy largely due to asymptomatic early progression of OC cells, late-stage diagnosis of the tumor, and the resistance of tumor cells to standard treatments. The most prevalent OC subtype, high-grade serous ovarian carcinoma (HGSOC), is the primary cause of most OC-related deaths.
