Communication During Perimmigration: A Life-Line Interview Method Study, Giada Roberta Rossi
Communication During Perimmigration: A Life-Line Interview Method Study, Giada Roberta Rossi
Communication & Theatre Arts Theses
This thesis examines the communication challenges faced by migrants and their impact on acculturation using a new approach. The study analyzed autobiographical memories of immigrants’ communication to explore both positive and negative experiences over time. The study extends previous intercultural communication research by using the Life-Line Interview Method (LIM) (Assink & Schroots, 2010) to collect autobiographical narratives from twelve participants about their communication journeys. The findings reveal consistencies with past intercultural communication research insofar as uncertainty and identity problems were pervasive, but also positively extends past research arguing that supportive environments, characterized by culturally responsive educators and peer networks, play …
It Ends With Us: How Social Media Algorithms Shape Recommendations In Online Reading Communities, Alana Nicole Whitley
It Ends With Us: How Social Media Algorithms Shape Recommendations In Online Reading Communities, Alana Nicole Whitley
Communication & Theatre Arts Theses
My thesis explores social media algorithms and their influence on recommendations of authors for people who engage with reading communities online. During a three-week research period, I examined algorithmic behaviors in online book communities using an alias. Findings revealed that BookTube, BookTok, and Bookstagram facilitate book discovery but offer weak algorithmic recommendations and suggestions. While social media algorithms excel at providing opportunities for creators and authors, they fail to promote trending and diverse books. These insights indicate that algorithms shape literary consumption by limiting readers’ choices. This research contributes to discussions of online reading communities and the role of algorithmic …
Beyond The Institution Of Motherhood: Shifting The Paradigm, Gabrielle Wilson
Beyond The Institution Of Motherhood: Shifting The Paradigm, Gabrielle Wilson
Graduate Research Conference (GSIS)
This paper explores declining birth rates as a global act of resistance and reclamation by women and birthing individuals against hyper-masculinized institutions, using South Korea's 4B movement as a case study. The 4B movement, which rejects marriage, childbirth, romance, and heterosexual relationships, represents a paradigm shift challenging entrenched gender norms, state control, and systemic inequities. It exemplifies a global phenomenon as similar movements gain traction in the U.S., Japan, and beyond, amidst rising conservatism and declining fertility rates. Framing this analysis with intersectionality, Feminist IR theory, and Kuhn’s paradigm shift model, the paper argues that this resistance signifies a transformative …
A Canvas Decolonized: An Exploration Of Haiti’S Colonial History Through Haitian Artists Philemon Obin, Jean Appolon, Sheilby Mecena, Flex Morisseau–Leroy, And Claes Gabriel, Dominique Dempsey
Graduate Research Conference (GSIS)
A Canvas Decolonized examines the complex realities faced by Haiti through the lens of its vibrant artistic heritage, highlighting the role of art in interpreting, preserving, and challenging narratives about the nation's history and identity. By exploring the works of Haitian muralists, photographers, painters, and poets including Jean Appolon, Flex Morisseau Leroy, Claes Gabriel, and Edwidge Danticat this study illuminates how these artists engage with themes of colonization, immigration, generational trauma, and cultural displacement. Grounded in the theoretical frameworks of Frantz Fanon and Benedict Anderson, the paper argues that Haitian art provides a powerful medium to analyze and contextualize the …
Modeling The Impact Of Nato Policy Actions On Taliban Disinformation Campaigns With Lotka-Volterra Models, Timothy Tarter, Bella Santos
Modeling The Impact Of Nato Policy Actions On Taliban Disinformation Campaigns With Lotka-Volterra Models, Timothy Tarter, Bella Santos
Graduate Research Conference (GSIS)
In this paper, we use an adaptation of the Lotka-Volterra Predator-Prey framework (via Affilit Et. Al.) to model the relationship between Taliban disinformation campaigns and NATO’s attempts to counter them. We find that aggression is a significantly preferred strategy over stagnation; this result should prompt decisionmakers to take strong stances against disinformation campaigns while maintaining a healthy defense against retribution. This leads us to propose the NATO Afghan Youth for Change program, which provides scholarships to individuals throughout the Afghan diaspora to become NATO influencers - a role which will both advance their personal goals and mitigate the spread of …
Research In Indigenous Historiographies: Oral History As Evidence For Federal Recognition Of Indian Tribes, Colette Haworth
Research In Indigenous Historiographies: Oral History As Evidence For Federal Recognition Of Indian Tribes, Colette Haworth
Graduate Research Conference (GSIS)
Significant to the field of cultural studies is the identification of cultural artifacts, which enable scholars to analyze the complexities of societies, comprehend cultural dynamics, and investigate the ways in which individuals and communities construct meaning and identity in cultural contexts. Oral history, an intangible cultural artifact, has been an important cultural identifier, particularly for marginalized individuals and communities. The development of critical oral history (COH) methodology has alleviated some of the criticism toward oral history as a valid methodology. In fact, some scholars contend that COH has moved beyond the realm of academic research to “provide a policy relevant …
Truth Subversion And The Challenges To International Order, David Acosta
Truth Subversion And The Challenges To International Order, David Acosta
Graduate Research Conference (GSIS)
This essay explores the increasing prevalence and impact of truth subversion on the liberal international order (LIO). It examines how modern disinformation campaigns seek to undermine shared epistemological foundations critical for international cooperation, and looks to answer the question: what impact does truth subversion have on international order? Furthermore, it investigates how truth subversion creates uncertainty, challenges alliances, and exacerbates security dilemmas. The essay identifies four core truth subversion tactics: disinformation, double speak, conspiracy theories, and flooding, and applies them to the 2014 Malaysian Airlines Flight 17 tragedy, where Russian actors employed these techniques to distort facts, challenge investigative findings, …
Zombie-Auras: Genai And Hybrid Text Production, Joshua Nieubuurt
Zombie-Auras: Genai And Hybrid Text Production, Joshua Nieubuurt
English Faculty Publications
This paper explores the iterative evolutions of textual production and their impact on the “aura” of texts, as conceptualized by Walter Benjamin. The study identifies three key phases of textual production: the natural, the mechanized, and the digitized, each progressively displacing the “cult value” of texts. This cult value is lost through increased ease of creation, reproduction, dissemination, and dislocation of creators and audiences in time and space. The advent of Generative AI (GenAI) marks the latest evolution, transforming the “aura” into a memetic “zombie” form—familiar yet opaque, evoking both the sublime and fear. By examining Benjamin’s notion of “aura” …

Think Again: How Communication Eportfolios And Work-Based Learning Foster Resilience Through Double-Looping, Megan Mize, Alison Lietzenmayer, Gary Beck
Communication & Theatre Arts Faculty Publications
In a changing professional landscape, students need more than disciplinary knowledge; they need tools for reflection, adaptability, and purpose-driven growth. At Old Dominion University (ODU), ePortfolios and work-based learning (WBL) are strategically embedded across the Communication curriculum to foster double-loop learning, a recursive, metacognitive process through which students not only reflect on outcomes but also interrogate the assumptions behind their choices. Drawing from a decade of institutional practice, course-based examples, and student reflections, this chapter illustrates how these high-impact practices (HIPs) help students connect coursework to career goals, revisit self-perceptions, and build resilience over time. By linking academic learning to …

[Introduction] "Hope is not like a lottery ticket you can sit on the sofa and clutch, feeling lucky. [...] Hope is an ax you break down doors with in an emergency." - Rebecca Solnit
In 2018, Cheryl Glenn wrote, "The work of feminist rhetorical historiography is far from done; in fact, it has just begun-and it is anchored in hope." Following Glenn, we explore hope in this cluster as a methodological imperative in the archives. Informed by theorists Paulo Freire, bell hooks, Rebecca Solnit, and Cornel West, the writers in this Cluster Conversation envision hope as a radical orientation toward …

In 2023, the U.S. Surgeon General warned the public of the current “loneliness epidemic” and its potential consequences on physical and mental health. One possible consequence of this epidemic is the growth of a movement defined by loneliness and isolation: the incel (“involuntary celibate”) movement. This warning presents a worrying glimpse at the future, as the incel movement, along with other parts of the manosphere, is one that espouses violently misogynist rhetoric which is intrinsically linked to right-wing extremism. While linguistic studies have been conducted on the speech of incels and other constituent movements of the manosphere, few of these …

"They Just Don't Have The "Doctor" In Front Of Their Name:" Dimensions Of Trust In Physician Assistants, Staci Defibaugh, Leah Onosato
English Faculty Publications
Physician assistants play a major role in healthcare delivery in the United States, yet what we know about how patients perceive the care they receive from PAs is limited. Prior research on patients’ impressions of PAs has focused primarily on survey data, limiting the scope of what we can learn about patient impressions to predetermined, quantifiable categories, and has focused on post-visit impressions of a single encounter. In an attempt to better understand patient impressions, we conducted open-ended, semi-structured interviews with 30 participants prior to their medical visit, focusing on general impressions of PAs. Through an analytic process of reflexive …

English Faculty Publications
[Introduction] If the long hot summer of 2020 marked a season of racial reckoning, it was also—now visible in retrospect—a moment for processing with the relation between digital technologies and power. 8:46 after all names not only an event, a murder, but the title of a short digital film. A film, moreover, that has found decisively counterposed audiences in its ongoing afterlives. A forensics of police violence, on the one hand, 8:46 also avails, in the shadier corners of the dark web, the pleasures of a snuff film. In this way, 8:46 is emblematic of a broader, and, perhaps, terminal …

The purpose of this study was to examine the lived experiences and multiple identities of disabled BIPOC trafficked women. The findings from this study help to identify a carousel of victimization experienced by disabled BIPOC trafficked women, starting with adverse childhood experiences, onto trafficking victimization that differed between Black and White women, and later while seeking services. These findings highlight the need for providers and researchers to think beyond monolithic identities and consider the intersecting ways in which various forms of oppression (ableism and racism) influence the experiences of disabled trafficked BIPOC women.

Discussion forums are one of the favored platforms for knowledge sharing. Given their popularity, copious research exists on understanding the linguistic and behavioral characteristics of forum conversations, so as to inform the design of many downstream applications including discourse visualization, sentiment analysis, and question answering. However, prior investigations have mainly focused on general forums designed primarily for sighted users, and as such the applicability of their findings to dedicated accessibility discussion forums frequented by blind screen reader users remains unanswered. To bridge this knowledge gap and facilitate the development of better-informed assistive technologies for blind people, we investigated language use …
