From Morphology To Machine Learning And Genomics: Understanding Phenotypic Variation In Wild Ducks, Sara Gonzalez

Open Access Theses & Dissertations

Understanding the genetic underpinning and distribution of phenotypic variation within and between divergent groups is core towards shedding light into how populations diverge and adapt, as well as how hybridization breaks or builds on these scenarios; and thus, central to evolutionary biology. In wild organisms, however, quantifying and linking phenotypic traits to underlying genetic processes, like mutation, gene expression, epigenetics and allele interactions, remains challenging. This difficulty arises from the complex interplay between morphology, environment, and gene regulation, as well as the logistical barriers of collecting and standardizing large-scale data across individuals and populations. As a result, researchers are increasingly …

Desmadre, Xiomarra Milann Gonzalez

Open Access Theses & Dissertations

My project functions as a collection of poems that each hold stories that tie them into the theme of their assigned subsection and into the greater narrative that each subsection creates, resulting in the takeaway from the overall manuscript. From the first word of the introductory poem, to the final line of the concluding, the poems take you on a journey from a feminine existence that is struggling at the helm of external, oppressive forces leading into a self-reckoning and embracing their own internal power within the systematic chaos and uncertainty that plagues them through the underlying notes of each …

Multi-Hop Hybrid Graph Neural Network, James Arthur

Open Access Theses & Dissertations

Graph-structured data appear across diverse domains, such as social networks, citation graphs, biological systems, and knowledge bases. Graph Neural Networks (GNNs) have emerged as a powerful framework for learning on such data, yet existing architectures face significant challenges. Graph Convolutional Networks (GCNs) suffer from over-smoothing as depth increases, Graph Attention Networks (GATs) introduce computational and statistical instabilities, and naïve multi-hop propagation inflates memory and computation while failing to adapt to topology. These limitations motivate the development of a new framework that is both expressive and scalable. This dissertation proposes the Multi-Hop Hybrid Graph Neural Network (MHHGNN), a novel architecture that …

Borderlines Of Becoming: Transfronterizx College Students Navigating Surveillance, Hybridity And Belonging Along The Us-México Border, Aylin Garcia

Open Access Theses & Dissertations

This narrative literature review examines the educational experiences of transfronterizx college students along the U.S.– México border, a population largely absent from higher education scholarship.

The purpose of it is to examine [un]happiness, a phenomenon influenced by the social, political, and economic systems in Western paradigms within a critical postmodern view, looking at the intricacies of schooling, as no studies have taken a bottom-up approach to investigate the voices of the main stakeholders: students, teachers, and administrators. My study questions whether a holistic, liberating, and socially responsive curriculum could engender a positive learning environment wherein happiness is sustainable. Within happiness studies, hope is essential, so much …

Investigating The Impact Of Bilingual Experience And Language Use Context On Cognitive Control In An Auditory Stroop Task, Christian Ruiz-Ortiz

Open Access Theses & Dissertations

Bilinguals are often reported to outperform monolinguals on executive control tasks, yet recent work suggests that any bilingual adaptations depend on how, and in which contexts, individuals use their two languages. The present dissertation tested whether specific dimensions of bilingual experiences (proficiency balance and daily interaction situations) predict the way listeners engage proactive (anticipatory) versus reactive (stimulus-driven) control when resolving non-linguistic conflict. Sixty young adults completed a non-linguistic auditory Stroop task that manipulated conflict expectancy both list-wide and item-specifically. Group-level analysis replicated classic proportion-congruency effects, but not the predicted proactive control signature, and transfer cost indexing reactive control was not …

A Sociocognitive Perspective On The Activation Of Productive Epistemic Resources In College Students' Understanding Of Chemical Equilibrium, Henk Steven Van Den Bogaard

Open Access Theses & Dissertations

Science education, particularly in higher education, has a content coverage problem: it has long been described as "a mile wide, an inch deep" in various consensus documents from the National Academies. In chemistry education, the most common general chemistry curriculum covers topics as chapters based on the popular Sienko and Plane 1960's general chemistry textbook. The limited time available in such fast-paced coverage may limit the instructor's modeling and assessment of key performances in developing a mechanistic understanding of complex chemistry phenomena. In this sociocognitive, qualitative investigation, general chemistry II students' responses to assessment prompts were used to activate cognitive …

On The Non-Reductive Analogical Language Of Chemistry: Visualizing Chemistry As An Aesthetic Practice, Demetrio Hernandez

Open Access Theses & Dissertations

In this thesis, I will consider in detail the analogical language of chemistry by identifying metaphysical assumptions and interpretations embedded in the thinking and communication of chemistry. I will explain the epistemological function and meaning of chemical symbolism and how its artistic design presents a unique opportunity to reflect about the philosophical aesthetic connections between chemistry and the humanities. I will thus consider the creative aspects of chemistry and suggest that the merging between art and science yields practical wisdom. My goal is to argue in favor of the idea of complementarity which suggests that scientific models best develop from …

Voice-Language Cues In Speech Comprehension, Andy An Huynh

Open Access Theses & Dissertations

Voice familiarity has a powerful effect on speech comprehension, improving both intelligibility and recall. Speaker consistency also benefits speech comprehension with better recall for words spoken by one versus multiple speakers. The goal of the present study was to test the hypothesis that the benefits of voice familiarity for bilinguals depend on the consistency between a familiarized voice and the language of production, with improved perception for words when the speaker produces in the same language versus in a different language. Highly proficient Spanish-English bilinguals performed a speech-in-noise transcription task. During a familiarization phase, participants listened to brief utterances in …

Imperial Ideology And Subversive Practice In Arthurian Legend, Emma Katherine Keppler

Open Access Theses & Dissertations

This project approaches Arthur and Arthurian legend as vital elements in British self-identification from the medieval period onward by examining narratives of national origin in legendary history, romance, and other forms of cultural production. In my readings of these texts, I am concerned with how national identity and otherness are constructed and negotiated in a literary space, how myths of utopian origins rely on the endorsement and glorification of cultures of violence that sustain and justify imperial enterprises in the Middle Ages and beyond. It is my argument that in the absence of actual voices of resistance, romance tropes often …
