Probing The Disequilibrium Chemistry Of Two Late T-Dwarfs Using Planetary Intensity Code For Atmospheric Scattering, Crystal-Lynn Jacqueline Bartier

Theses and Dissertations

We have performed a detailed analysis of the atmospheric properties of two late-T type brown dwarfs, 2MASSI J0415195-093506 and 2MASS J05591914-140448. For each brown dwarfs, we combined the spectra of each brown dwarf from the ground at 1-2.5 µm, AKARI at 2.5-5 µm, and from the Spitzer Space Telescope at 5-15 µm. For this project, we are particularly interested in probing the extent of vertical mixing. For this analysis, we used the Planetary Intensity Code for Atmospheric Scattering (PICASO), which is a code that creates a radiative transfer model for a given set of atmospheric parameters. With PICASO we find …

The Relational Good Life: Entrepreneurship Education And Grounded Sumak Kawsay In Otavalo, Ecuador, Vanessa I. Lozano Hardman

Theses and Dissertations

Indigenous Kichwa communities in Ecuador’s Otavalo region have long participated in local and transnational markets, historically as mindalaes, specialized traders of the northern Andes. Yet in recent years, international development-oriented NGOs have framed entrepreneurship education as newly necessary for economic development. These approaches emphasize individualized narratives of vision, self-reliance, and growth, often characterizing Indigenous peoples as lacking entrepreneurial skills or the appropriate mindset. Drawing on ethnographic research with youth, mothers, and teachers at Saminay–El Legado, an agro- technical, intercultural bilingual secondary school (UECIB) in the parish of San José de Quichinche, this article examines how entrepreneurship education intersects with grounded …

Contesting Protection: Digital Moral Discourses On Child Marriage In Bangladesh, Mashaekh Hassan

Electronic Theses and Dissertations 2020 - Present

This thesis examines how child marriage is represented and morally negotiated on the official Facebook page of UNICEF Bangladesh. Drawing on transnational and Third World feminist critiques of development, it uses feminist content and discourse analysis to analyze twenty-five campaign posts and 2,677 comments (May–July 2025) to trace patterns of representation and moral reasoning. The analysis identifies three dominant representational patterns: child marriage as a rural girls’ issue, rural girls as constrained and victimized, and education as a universal solution, collectively producing a homogenized image of vulnerable girlhood. Two clusters of moral discourse emerge: pro–child marriage (privileging religious morality, critiquing …

Distilled Identities: The History And Gender Politics Of The Perfume Industry, Emma Shaffer

Honors Projects

This paper analyzes the use of gendered perfume marketing in the West. Drawing upon the work of Joe Schwartz, Sarah Evrett, and others, I examine the history of this phenomenon and the politics keeping the perfume market segregated by gender. How long has perfume existed? Has it always been so strict on who wears what fragrance? My results found that perfume has only been gendered since the Victorian era, dispelling the myth that gendered fragrance is the only way to market perfume. However, I also found that when gender neutral fragrances have been introduced, they have not had much staying …

Silent Struggles: A Qualitative Study On Mental Health Stigma And Help- Seeking Among African Individuals In The U.S, Ololade Ekwere

Dissertations

Approximately one-third of African Americans and Caribbean Blacks who require mental health services seek and utilize them (Evans & Sheu, 2019). Research has shown that stigma surrounding mental health treatment contributes to lower rates of professional help-seeking among Black Americans (Pederson, 2023).

Church, Mosque, And State: The Impacts Of Sectarian Politics On Lebanon’S Democracy, Tonia Attie

Departmental Honors & Graduate Capstone Projects

As Lebanon seeks to reform multiple sectors of the country, it is crucial to understand how its consociational government, centered on religious identities, interacts with its citizens. Electoral accountability is the process by which an electorate holds politicians liable for their actions while in office. While previous studies, such as Vincent Hutchings’ “Public Opinion and Democratic Accountability,” have shown how electoral accountability functions within traditional party systems based on political ideology, there is little research on how accountability mechanisms operate in confessional party systems based on religion. This paper posits that within countries with confessional systems, voters are less able …

A Masked-Perturbation Model For Destabilization Security Games In Feedback Systems, Gabriel Michael Perry

Theses and Dissertations

In this thesis, we present a mathematical formulation for increasing cyberphysical system security. This model allows a system administrator to use assumptions about exposed signals to derive defense strategies meant to mitigate the system's vulnerability to feedback perturbation attacks. We begin with a survey of game theory with the goal of building the concepts of resource and security games. We then introduce our model, which is a security game; targets in this game are exposed signals in the model map of the system, and resources are perturbed or introduced dynamical relationships between these signals. This formulation, called the masked-perturbation model, …

Theoretical Expressivity Of Self-Attention As A Model Of Binary Sequence-To-Sequence Functions And Other Explorations, Dustin Angerhofer

Theses and Dissertations

The self-attention mechanism lies at the heart of modern sequential modeling with deep neural networks, especially in the context of Large Language Models (LLMs). The basic role of self-attention is to capture pairwise interactions between tokens in a sequence. This allows token embeddings to be endowed with context-dependent information before further processing. Despite its widespread use, our theoretical understanding of self-attention is still nascent. In this work, we examine self-attention as a model of binary sequence-to-sequence (seq2seq) functions, which is the simplest non-trivial case to analyze. We find, using VC dimension and the Sauer-Shelah lemma, that in the limit of …

Principal Coaching Impact: Elementary Principals' Perspectives On Their Coaching Experience, Kyle L. Hoopes

Theses and Dissertations

School principals face increasing complexity as they navigate instructional leadership, organizational change, and the emotional demands of supporting staff and students.
