Fact-Checking As A Multi-Step Process: From Ambiguity Resolution To Claim Validation, Wenbo Wang

Dissertations

The spread of misinformation and disinformation has become a major concern, particularly with the rise of social media as a primary source of information for many people. Fact-checking—the process of verifying claims against credible evidence—has emerged as a critical safeguard against misinformation. Yet, the task is fraught with challenges: claims are often ambiguous, context-dependent, or composed of multiple intertwined assertions, while automated systems struggle to replicate the nuanced reasoning of human experts. This dissertation addresses these challenges by reimagining fact-checking as a multi-step, knowledge-guided process that systematically resolves ambiguity, decomposes complexity, and validates claims through structured reasoning. Additionally, the proposed …

From Neural Networks To Large Language Models: Innovations In Financial Ai, Mathematical Reasoning, And Structured Data Representation, Junyi Ye

This dissertation explores the evolution and application of artificial intelligence techniques across three critical domains: financial modeling, mathematical reasoning, and structured data analysis. The dissertation presents seven research projects that chart a progression from specialized neural architectures to sophisticated large language models (LLMs), contributing novel methodologies and frameworks at each stage.

In the financial domain, the research first introduces TS-Mixer, a MLP-based architecture for time-series forecasting that captures both feature relationships and temporal dependencies through a simple yet effective design, outperforming more complex models in S&P500 index prediction. The dissertation then presents DySTAGE, a dynamic graph representation learning framework that …

Transplant Transplant(Ed) Transplant(Ing), So Jung Yoon

Masters Theses

Boundaries shape our lives and identities. The tangible presence of boundaries becomes a medium for engaging with the world—such as who occupies a space and how, or what tools are deemed valid in a design process. These boundaries aren’t always visible; they’re embedded in systems, habits, and assumptions that shape how we move, create, and are recognized. They extend far beyond fixed geographies and the specific positions we occupy within them.

Transplanting is the process by which things are moved or move across boundaries in hopes of being planted, finding a place to stay. Though it can be a search …

Naming People, Making Bodies: Reflections On Tukano Onomastics, Geraldo Andrello

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article discusses the topic of names and naming among Amerindian peoples, in particular among Tukano speakers on the Uaupés River, northwestern Amazon. After reviewing the analytical contrast between endonyms and exonyms (i.e., internal transmission of names taken from ancestors versus the capture of names from extra-human sources), I explore endonymic systems through an examination of differences between the Jê and Tukano, considered to be exemplary cases of this naming regime. The Tukano case, explored in more depth towards the end of the article, provides elements that indicate an articulation between both regimes as well as a complex dynamic between …

Do Myths Ever Die? Social-Cultural Changes And Mythical Transformations In Indigenous Amazonia: A Dialogue With Peter Gow, Aparecida M. N. Vilaça

Tipití: Journal of the Society for the Anthropology of Lowland South America

This is the first Peter Gow Memorial Lecture, given at the University of St Andrews in February 2024. Based on the analysis of different versions of Wari’ myths (Rondônia, Brazil) collected over forty years, the paper has two central objectives. The first is to engage with Peter Gow’s analysis of the mythical transformations resulting from the historical changes experienced by the Piro/Yine Indigenous people of Peru. The second is to discuss Lévi-Strauss’s suggestion that a myth can “die” after successive transformations, exhausting itself, taking the form of romantic tale or legendary tradition.

An X-Ray Of Mẽbêngôkre Houses In Terms Of Matrimonial Alliance, Vanessa R. Lea, Leandro Mahalem De Lima

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article examines the matrimonial implications of the Houses, or matrihouses, of the Mẽtyktire subgroup of the Mẽbêngôkre (Kayapó-Jê) with the assistance of Puck (Program for the Use and Computation of Kinship Data) and Pajek software. In accordance with the greater legibility of graphics, statistical results have been converted into graphics whenever possible. The analysis is based on a revised version of a dataset spanning the years 1978 to 1982 and published on the site Kinsources. What began as a village census later morphed into genealogies, which served as the basis for the digital dataset. The matrihouses …

Ser Nhande’I Va’E, Da Concepção Aos Primeiros Passos: Uma Abordagem Etnográfica Sobre A Permanência, O Movimento E A Palavra, Maria Inês Ladeira

Tipití: Journal of the Society for the Anthropology of Lowland South America

O evento do nascimento, assim como os ritos de passagem, são temas recorrentes na literatura etnográfica, com destaque aos resguardos, condutas e preceitos. Neste artigo, ao versar sobre o ato de nascer, refiro-me a alguns princípios referenciados na cosmologia guarani, na qual esse acontecimento é também um marcador – marco espaço/temporal – dos lugares habitados – isto é, ação de territorialização. Determinadas condutas pré e pós-parto são fundamentais para os Guarani Mbya e os Ava Guarani se socializarem com os demais viventes nas matas/terras que conformam seu território (Yvyrupa). A partir desse prisma, ressalto algumas propriedades e combinações …

Enactive Narrativities: Rubber-Times Historicity And Indigenous Media In Peruvian Amazonia, Gabriel Torrealba Alfonzo

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article analyzes the intersection between historicity and politics expressed in Kukama media-making practices. It examines the political and enactive dimensions involved in the Indigenous mediatization of rubber-era narratives in Peruvian Amazonia. I focus on the case of Radio Ucamara, a Kukama radio station from the Peruvian town of Nauta, and the ways in which they confront private and state powers through the production of digital and non-digital media. I specifically analyze Indigenous media-makers’ instrumentalizations of rubber-times narrativity by virtue of aesthetic mastery. Radio Ucamara media relies on a polyphonic strategy that encapsulates both narrative and meta-narrative discourses aimed to …

Coloca-se em pauta a desconstrução dos corpos e pensamentos que os indígenas são submetidos ao adentrar na universidade, …

Baniwa Speculative Kinship, João Vianna

Tipití: Journal of the Society for the Anthropology of Lowland South America

This article discusses the dynamics of Indigenous kinship in the Amazon, based on the autobiographical narrative of Mr. Júlio Cardoso, a ninety-year-old man of the Baniwa people. From his account, I develop an ethnographic discussion on the Baniwa, speakers of an Arawak language and inhabitants of the Upper Rio Negro, with a particular focus on the relationships between Indigenous and non-Indigenous peoples. Júlio’s life is highlighted due to his extended period living with patrões from the regional aviamento system between the 1950s and 1970s. One of Júlio’s most recurrent formulations regarding these non-Indigenous bosses is that they were “as if” …

Problematizing A Hegemonic English: An Assessment Of Language Use And Diversity In A Nation Of Immigrant Communities, Charlotte Choat

Honors Projects

The increasing development of language diglossia between global English and local languages around the world raises questions of how the American linguistic character will react. In a culture defined by its lack of ethnolinguistic definition, can language localization occur? A study of language development in America requires a historical assessment of language contact, discourse, and dominance. The present state of American English is not the natural result or authentic representation of America’s population, but the outcome of language restrictionism and resource disparity enforced on many ethnolinguistic groups throughout American history. In the modern era of intensified immigration, ethnolinguistic diversity is …

Sociology: Culture, Marcia Morrison

Open Educational Resources

This work examine culture. It begins by examining the foundations of culture to include norms, values, language, symbols and knowledge. In looking at each, it breaks down the implication of each to the development of ourselves as well as the person in the environment. It moves on to look at contexts of culture such as dominant cultures juxtapose to competing cultural systems, and how the various elements of culture can serve to either promote or minimize the various cultural constructs within society.

Constructing Portraits Of Elementary Teachers Of Ethnic Studies: Examining The Narratives Of Anti-Racist Educators In An Era Of Common Core Curriculum And Instruction, Jennifer S. Manglicmot

Dissertations

The emergence of policies requiring ethnic studies courses in California’s secondary and higher education institutions amplified calls for anti-racist pedagogy and content in all K-12 grade levels. Currently, little empirical research exists on how ethnic studies is taught in elementary school classrooms. This absence is significant because instruction in these settings tend to focus heavily on meeting state content standards (i.e. Common Core), frameworks which have been critiqued as ignoring communities of Color epistemologies and promoting color-evasive ideologies, among other concerns. Through interviews, classroom observations, and document analysis, this qualitative multiple-case study explored how anti-racist and ethnic studies pedagogies are …

Embodying Altruistic Love: The Role Of Emotions In Teaching Black Students With Disabilities Within An Inclusive Elementary School, Joshua Armentrout

Graduate Doctoral Dissertations

Teacher emotions play a pivotal yet understudied role in shaping the educational experiences of Black students with disabilities (SWDs). This study examines how five special educators in a fully inclusive elementary school understand, experience, and navigate their emotions in relation to Black SWDs. Using a qualitative approach grounded in portraiture, this study explores the intersection of race, disability, and emotion, revealing how teachers internalize, resist, and negotiate dominant ideologies within the broader educational system.

Guided by a three-dimensional space framework from the field of narrative inquiry—temporality, sociality, and spatiality—this study traces how educators’ emotions are shaped by past experiences, social …

A Teacher, A Tutor, A Friend: Chatgpt And The High School Experience, Saisha Gupta, Vivek Mehta, Rebecca Kam, Caroline Ehmann, Alma Orgad, Emily Kuang, Alejandro Castro Barrantes, Matthew Posada, Samay Shah, Nikhita Prasad, Tara Pai, Eileen Ho, Shirley Xi, Tianyi Zhou, Elaina Li, Stephanie Wan, Shreya Paranjape, Zoe Dearling, Siqi (Grace) Peng, Aanya Kaveti, Gwendolyn Lowrance, Angela Ziyi Xie, Mira Xu, Adhiti Hariram, Alexa Muse

The Qualitative Report

Given the increasing emergence of artificial intelligence (AI) in education, high school students' perspectives on ChatGPT are underrepresented in current research literature. As high school student researchers in an English Language Arts course, we approached this gap in literature by asking the question: In what ways do pressures within high school communities influence students’ perspectives on justifying or rejecting the use of ChatGPT? We interviewed 24 secondary students and conducted a thematic and discourse analysis, coding the interviews through the lenses of social goods (Gee, 2014), Figured Worlds (Holland et al., 1998), and positioning theory (Holland et al., 1998; Ingram …

A Teacher, A Supervisor, An Undefined Self, Alexa Muse

The Qualitative Report

This article follows the experiences and reflections of an American high school English teacher while evolving a single tenth grade memoir and grammar unit into a published student-led research project over the span of 3 years. As a partner piece, this article supplements my students’ published project, titled “A Teacher, a Tutor, a Friend,” that explores ChatGPT and student perspectives through a thematic discourse analysis under the framework of Figured Worlds (Holland et al., 1998); as their teacher-turned-supervisor, I found that preparing 10th grade students—now called the Lexington Student Research and Publication Collaborative—to grapple with such complex material was a …

The study identifies recurring frames, themes, and narratives, highlighting differences between traditional media and social media platforms in their portrayal of Sudanese refugees. Key findings reveal that neutral tone dominate traditional media, focusing on factual reporting, followed by negative, then positive tones. Conversely, social media predominantly features negative narratives, such …

The Power Of Storytelling: Creatively Facilitating Conceptual Change In The Classroom, Mackenzie S. Rose, Marcus Johnson

Journal of Educational Research and Practice

Conceptual knowledge encompasses understanding the interrelationships among multiple pieces of information. Misconceptions of these interrelationships illustrate the need for effective educational strategies to facilitate conceptual change, with the goal of facilitating changes in learner understanding to appropriate, accurate, and complete concepts. Strategies, such as refutation texts, have proven effective in addressing science misconceptions, yet there is a prominent gap in research on conceptual change in nonscience subjects and the use of storytelling to facilitate such change. Storytelling, presented in a range of educational subjects, invites learners to engage in social discourses and problem-solving exercises. Prompted by classroom storytelling practices, creativity, …

Upward Mobility Of First-Generation Low-Income Dartmouth Students, Robin T. Frye

It offers three significant contributions to the field of adaptation planning: (i) It demonstrates how to integrate a stakeholder-specific assessment within the DAPP framework and illustrates individual impacts to a variety of stakeholders, including high- and low-income residents, commercial actors, government actors, and coastal landowners hoping that the planning process remains transparent and motivates local …

The White Elephant In The Classroom: Using Local History And Resource Pedagogies To Remove It, Dawn N. Colquitt-Anderson

Graduate Doctoral Dissertations

Years of scholarship outline the benefits of asset-based pedagogy for all students, especially the culturally and linguistically diverse students who are now the majority student population in public schools. But there is scant research on how experienced in-service teachers modify their practices and beliefs to adequately prepare these students for 21st century leadership. This sequential mixed methods case study examined the efforts of elementary and middle school teachers as they grappled with personal, professional, and systemic barriers that arose as they worked to strengthen their cultural and community responsiveness by centering the local history of a historic great migration town.

Multilingual English Teaching: Challenges And Possibilities In The Secondary Mainstream Classroom, Vannessa Quintana Sarria

Protein Word Detection Using Text Segmentation Techniques, Ashish V. Tendulkar, Sutanu Chakraborti, Ganesh Devi

Journal of Global Awareness

Literature in Molecular Biology is abundant with linguistic metaphors. There has been works in the past that attempt to draw parallels between linguistics and biology, driven by the fundamental premise that proteins have a language of their own. Since word detection is crucial to the decipherment of any unknown language, we attempt to establish a problem mapping from natural language text to protein sequences at the level of words. Towards this end, we explore the use of an unsupervised text segmentation algorithm for the task of extracting "biological words” from protein sequences. We demonstrate the effectiveness of using domain knowledge …

Operational Endings, Emotional Impacts: Ethical Considerations When Project Teams Form Attachments To Ai Collaborators, Tom Wise, Sarah M. Dyson, Stephen Onu, John Clark, Joseph Zagerman, Jennifer Williams

Beyond the Project Horizon: Journal of the Center for Project Management Innovation

The project investigated responses to an AI displaying emotional qualities, such as fear, through a mixed-methods approach. Participants were randomly assigned to one of two scenarios—one featuring an AI coworker and the other a human coworker and evaluated for emotional attachment and loss. Results revealed that professionals exhibited significant emotional responses to the potential "termination" of an AI team member. Qualitative analysis identified eight themes, including emotional responses and termination. Findings suggest that emotionally expressive AI activates psychological processes akin to human relationships, with implications for AI design, workplace dynamics, and ethical considerations surrounding AI termination.

Teaching Transcription For Social Justice In Linguistic Anthropology, Thea R. Strand, Michael Wroblewski

Anthropology: Faculty Publications and Other Works

The careful transcription of socially-occurring speech can be usefully incorporated into undergraduate classes in linguistic anthropology through in-class practice, discussion, and, especially, as a formal assignment. Teaching transcription—a key method for professional linguistic anthropologists—is particularly effective for engaging students in active learning of key disciplinary principles, as well as promoting critical (self-)awareness of, and reflection on, sociolinguistic practice. As students’ written reflections on transcription assignments show, teaching close transcription contributes to deepened understandings of the fundamental characteristics and complexities of human speech, the key roles language plays in social interaction and inequality, and how they might apply these lessons toward …
