A New Brood: The Return Of China's Green Cicada, Ella Murray, Darren L. Linvill, Patrick Warren Feb 2026

A New Brood: The Return Of China's Green Cicada, Ella Murray, Darren L. Linvill, Patrick Warren

Media Forensics Hub Reports

This report examines a network of AI-assisted accounts purporting to be from Australia, the United States, or the Philippines, posting AI-generated commentary on X about each country’s politics and culture. It is very likely that this network originates in China and is facilitated by an LLM given the coordination of their messaging and the structure of the content itself.


Courts Of New York: A Visual Atlas Of The City’S Public Basketball Spaces, Nathaniel Rattner Feb 2026

Courts Of New York: A Visual Atlas Of The City’S Public Basketball Spaces, Nathaniel Rattner

Dissertations, Theses, and Capstone Projects

Basketball courts in New York City are recreation facilities, community anchors and part of the city’s cultural image. In the basketball capital of the world, New Yorkers are rarely more than a few blocks away from a court. The visual diversity of these courts, however, is not widely documented in systematic ways.

This project makes that diversity visible to the public, combining open data, aerial imagery and computational analysis to document this important public space across the five boroughs. It is a narrative story and digital atlas of New York City’s public basketball courts, using surface color as a way …


Media Use And Pro-Equality Attitudes Toward Women As Leaders, Mark Tremayne, Dustin Harp, Ariana Hernandez Feb 2026

Media Use And Pro-Equality Attitudes Toward Women As Leaders, Mark Tremayne, Dustin Harp, Ariana Hernandez

Communication Faculty Publications

This study examines how Americans’ media use corresponds with attitudes toward women as leaders. We surveyed 1,030 adults and measured pro-equality attitudes using a 17-item index. Newspaper reading and streaming video use were positively associated with pro-equality views, while time spent on social media (particularly Facebook and X) showed small negative associations. Participants who used newspapers for political content reported higher pro-equality scores than non-users, whereas those who used X for politics reported lower scores. The findings suggest that media habits and political ideology are connected to gender attitudes.


Rethinking The Mindfulness And Mindlessness In Media Evocation Of Human-Machine Communication: A Case Study On The In-Car Robot “Nomi”, Bing Wang, Longxiang Luo, Weizi Liu Jan 2026

Rethinking The Mindfulness And Mindlessness In Media Evocation Of Human-Machine Communication: A Case Study On The In-Car Robot “Nomi”, Bing Wang, Longxiang Luo, Weizi Liu

Human-Machine Communication

The commonly used Media Equation framework in human-machine communication research exhibits limitations when explaining human-machine relationships in the AI era, giving rise to the Media Evocation paradigm. Based on the Media Evocation framework, this study employs in-depth interviews to investigate whether interactions between humans and the in-car robot Nomi are mindful or mindless, while also examining whether these interactions prompt reflections on the machine’s ontology. The findings indicate that most participants perceive Nomi as a human-like actor and interact with it mindfully. Highquality social cues, such as voice and facial expressions, can trigger mindful anthropomorphic responses in human-machine interaction, eliciting …

Normalizing Ai: The Evanishing Effect And Rethinking The Machine Heuristic, Bumju Jung, Cameron W. Piercy, Patric R. Spence Jan 2026

Normalizing Ai: The Evanishing Effect And Rethinking The Machine Heuristic, Bumju Jung, Cameron W. Piercy, Patric R. Spence

Human-Machine Communication

This study examines how people evaluate factual claims attributed to human journalists versus artificial intelligence (AI) news bots, and how these evaluations are shaped by individual endorsement of the machine heuristic. An online experiment (N = 233) used a 2 (Agent: human vs. AI) × 2 (Information Veracity: accurate vs. inaccurate) design in which participants viewed a short tweet embedded in either a human or AI profile and then rated perceptions of source credibility, objectivity, bias, and accuracy. Endorsement of an AI-focused machine heuristic was significantly associated with higher source credibility, perceived objectivity, and perceived accuracy, and lower perceived bias, …


Ai Humanizers, Pragmatists, Skeptics: A Cluster Analysis Of Normative Attitudes For Ai’S Capabilities And Roles, Kate K. Mays, Ekaterina Novozhilova Jan 2026

Ai Humanizers, Pragmatists, Skeptics: A Cluster Analysis Of Normative Attitudes For Ai’S Capabilities And Roles, Kate K. Mays, Ekaterina Novozhilova

Human-Machine Communication

This study explores people’s attitudes about artificial intelligence’s (AI) capabilities through a normative lens. Drawing from literature on phenomenological, ontological, and heuristic judgments about machines, we aim to better understand what capabilities people think AI should be able to have and how that relates to enthusiasm about having AI take certain roles in their lives. Survey participants (N = 601) were grouped via two-step clustering based on their attitudes, revealing three clusters: AI humanizers, who expect empathy and social interaction from AI; AI pragmatists, who expect cognitive capabilities; and AI skeptics, who prefer AI with limited human-like traits and emphasize …


Explain. Write. Edit. Summarise: An Exploratory Study On Agency Negotiations In Student-Chatbot Conversations, Árni Már Einarsson Mr, Ekaterina Pashevich Jan 2026

Explain. Write. Edit. Summarise: An Exploratory Study On Agency Negotiations In Student-Chatbot Conversations, Árni Már Einarsson Mr, Ekaterina Pashevich

Human-Machine Communication

LLM-based chatbots such as ChatGPT have given technologies that traditionally operated on the back end a user-friendly, conversational interface. Their rapid adoption among students has prompted universities worldwide to issue guidelines and re-examine existing practices. Supplementing prior research based on discourse analysis and self-reported measures (e.g., surveys and interviews), we propose an approach for analyzing naturally occurring student–chatbot interactions, rooted in conversation analysis of chats (n = 503) donated by eight current Danish university students. The analysis identifies conversational patterns across three main types of activities and examines how agency is negotiated across the structural dimensions of signification, domination, and …


Two Years To Madness: A 30-Month Journal Of Human–Machine Communication And Second-Hand Reality, Andrew Prahl Jan 2026

Two Years To Madness: A 30-Month Journal Of Human–Machine Communication And Second-Hand Reality, Andrew Prahl

Human-Machine Communication

Drawing on a 30-month analytic-autoethnography of the first author’s journal as an earlyaccess OpenAI user, this study examines how sustained communication with generative AI affects everyday lived experience and identity. Inductive content analysis of 166 entries by independent coders is followed by theory-driven coding with the extended-mind and sensemaking frameworks. Three interlocking themes emerge. Enabled and Degraded captures the tension between new capabilities and efficiency versus creeping skill atrophy. Scary New World charts rising anxiety as productivity gains erode competitive and relational distinctiveness. The findings also show a growing, pervasive doubt about the human authorship of texts, images, and other …


The Material Condition: A Practice Theory-Oriented Infrastructural Turn To The Ethics Of Human-Ai Communication, Anne Mollen, Sigrid Kannengießer Jan 2026

The Material Condition: A Practice Theory-Oriented Infrastructural Turn To The Ethics Of Human-Ai Communication, Anne Mollen, Sigrid Kannengießer

Human-Machine Communication

This paper calls for an infrastructural turn in human–AI communication, centered on the materiality of generative AI. We argue that a nuanced understanding of ethical implications of generative AI necessitates examining the socio-technical infrastructures that constitute these systems. These infrastructures encompass not only technological artifacts but also human actors (developers, users, data subjects, etc.) and their practices as well as social contexts in designing, developing, implementing, and maintaining AI. Therefore, we propose to adopt a practice theory approach, to analyze how ethical concerns materialize within these infrastructures. This perspective reveals how infrastructures are contested spaces in global production chains, highlighting …


Whole Earth Machines: Human-Machine Communication For A Green Transition, Klaus Bruhn Jensen Jan 2026

Whole Earth Machines: Human-Machine Communication For A Green Transition, Klaus Bruhn Jensen

Human-Machine Communication

The climate crisis of the 21st century represents an existential risk to humanity and biodiversity, posing essential questions of how communication may serve to coordinate mitigation of and adaptation to climate change. One recent response has been massive investments by governments and corporations in systems providing feedback on the state of Earth— Whole Earth Machines (WEMs). For human-machine communication (HMC) studies, WEMs invite sustained engagement with communication infrastructures as a key constituent of research agendas, beyond the interface encounters at the center of many HMC studies to date. The article presents a conceptualization and operationalization of WEMs as critical infrastructures …


Critical Design And The Robotic Imaginary: Design Criticism And Critical Robots, Jörgen Behrendtz Jan 2026

Critical Design And The Robotic Imaginary: Design Criticism And Critical Robots, Jörgen Behrendtz

The Journal of Sociotechnical Critique

This paper brings critical design and design criticism to critical robot studies. Critical design can be described as an umbrella term for approaches making use of speculative designs to highlight and challenge narrow assumptions, preconceptions or even taken-for-granted truths about the role products play (in a wide sense) in everyday life. Design criticism refers to a reasoned procedure that investigates emancipatory and/or limiting potentials of designs, theorizes the roles of affordances, materials and embodied perception as epistemological resources in media interaction, and clarifies connections between specific design choices and their associated experiential qualities, seductive powers, ideological underpinnings, material operations, and …


Strategi Personal Branding Youtuber Asian Survivor Dalam Membangun Motivasi Donasi: Studi Analisis Konten Video Youtube, Muhammad Sulthon Asykur, Hasyim Asyari Jan 2026

Strategi Personal Branding Youtuber Asian Survivor Dalam Membangun Motivasi Donasi: Studi Analisis Konten Video Youtube, Muhammad Sulthon Asykur, Hasyim Asyari

Jurnal Administrasi Bisnis Terapan

ABSTRACT

Content creators face significant challenges in maintaining audience engagement and social relevance amidst dynamic platform algorithms. This study analyzes YouTuber Asian Survivor's personal branding strategy in building authenticity, engagement, and audience donation motivation using a mixed-methods approach. Quantitative analysis employed t-tests and binary logistic regression on 101 videos, while qualitative analysis was conducted through in-depth interviews and observation. Results indicate that neither vulnerable nor inspiring narrative types significantly differentiate engagement levels; however, videos that successfully raised donations exhibited significantly higher engagement rates. Regression analysis proved that an increase in engagement rate raises donation probability by 2.5 times. Qualitative findings …

Crystal Sets And Listening-In: Radio In Ireland Before 2rn, Stephanie Rains Jan 2026

Crystal Sets And Listening-In: Radio In Ireland Before 2rn, Stephanie Rains

Irish Communication Review

When 2RN began broadcasting from its studios on Henry Street in Dublin on 1 January 1926, it became the first radio station in the Free State. However, it was very far from being the start of radio on the island of Ireland, as there was already a community of amateur operators and engineers conducting technical experiments. This article explores the radio landscape in Ireland which 2RN joined and transformed. The early enthusiasts often not very concerned with programming or with most of radio’s possibilities as a form of entertainment, but did have a very international perspective on the medium’s possibilities. …

Initial Validation Of The Teleoperator-Avatar Robot Interaction Scale (Tarx), Nicholas Bowman, Rio Harper, Jaime Banks Jan 2026

Initial Validation Of The Teleoperator-Avatar Robot Interaction Scale (Tarx), Nicholas Bowman, Rio Harper, Jaime Banks

Media Studies - All Scholarship

Extant work on human-machine relations indicates humans experience variably social relations with machines. However, there is yet no systematic framework for considering the potential sociality of relations between teleoperators and controlled robots, in addition to their functional associations. We bridge that gap by initially validating a proposed-butuntested measurement model of teleoperator/avatarrobot interaction (the TARX scale) inspired by gamebased player-avatar relations. In a lab-based study of human operators’ subjective experiences in remotecontrolling a robotic arm, we find support for the hypothesized factor structure comprising four dimensions: Relational closeness, anthropomorphic autonomy, critical concern, and sense of control. Results demonstrate the coherence of …


An Eye For An Eye And A Smile For A Smile: Examining Aggressive And Supportive Behavioral Alignment Among Taiwanese Adolescence Who Play Video Games, Nicholas Bowman, Chrissy Cook, Chingching Chang Jan 2026

An Eye For An Eye And A Smile For A Smile: Examining Aggressive And Supportive Behavioral Alignment Among Taiwanese Adolescence Who Play Video Games, Nicholas Bowman, Chrissy Cook, Chingching Chang

Media Studies - All Scholarship

The social dynamics of video games, especially those played online, are one of the primary motivators for gaming. Unfortunately, while there are numerous benefits to online gaming, there is also potentially harmful toxic and aggressive behavior. Prior research has investigated toxicity, but most studies rely on convenience samples, typically from WEIRD populations. The current study extends this scholarship with a nationally representative sample of Taiwanese adolescents who are frequent gamers, (a) quantifying their experiences with aggressive and supportive behaviors in games and (b) investigating personological-level variables that might explain reciprocating (referred to as “behavioral alignment”). Key findings were (1) aggressive …


Simulated Intimacy, But Real Connection: Perceived Reciprocity And Romantic Closeness Make Otome Fun To Play, Nicholas Bowman, Elena Yifei Zhao Jan 2026

Simulated Intimacy, But Real Connection: Perceived Reciprocity And Romantic Closeness Make Otome Fun To Play, Nicholas Bowman, Elena Yifei Zhao

Media Studies - All Scholarship

Otome games offer players the opportunity to form romantic relationships with NPCs. Drawing on Social Exchange Theory, we proposed that, in the context of otome game, reciprocity enhances the sense of romantic closeness with NPCs, which in turn lead to greater enjoyment and appreciation. Survey data from 293 Chinese otome players supported the model, suggesting that at least one of the reasons that otome gaming is so entertaining is that they provide players with relationships that those players engage as if they were authentically social. Descriptive results revealed high reciprocity scores and strong romantic connection with NPCs, which players feeling …


Digital Diplomacy And Activism: Sustaining Institutional Legacy Through State-Proxy Discursive Competition In The Aftermath Of The Usaid 2025 Suspension, Maryam Alaa Elprince Jan 2026

Digital Diplomacy And Activism: Sustaining Institutional Legacy Through State-Proxy Discursive Competition In The Aftermath Of The Usaid 2025 Suspension, Maryam Alaa Elprince

Capstone and Graduation Projects

This study examines how the 2025 suspension of the United States Agency for International Development (USAID) transformed the arena of U.S. foreign-aid diplomacy by eliminating the agency’s operational capacity and erasing its digital presence, thereby redistributing discursive authority across a fragmented communicative field. The research aims to determine how diplomacy adapts when a bilateral institution central to American soft power is dismantled through top-down decision, and whether discursive power exercised online can extend institutional relevance and legitimacy beyond structural collapse. Using an interpretivist qualitative design that combines digital-forensic reconstruction, document-based content analysis, and elite interviews  with top ranking officials, the …


Determinants Of Digital Piracy: An Integrated Model, C. Christopher Lee, Peiyao Chen Jan 2026

Determinants Of Digital Piracy: An Integrated Model, C. Christopher Lee, Peiyao Chen

Journal of International Technology and Information Management

Digital piracy is a form of copyright infringement, and challenges persist in addressing it effectively. Accordingly, understanding why people engage in digital piracy is crucial. Although prior studies have examined digital piracy from multiple perspectives, existing studies on the explanatory factors of digital piracy remain fragmented. To address this research gap, this study develops an integrated model that incorporates key theoretical perspectives, neutralization theory, social learning theory, and the theory of planned behavior (TPB), along with key determinants including gender, age, and the technology factor. Rather than conducting a meta-analysis of previous studies, this study adopts a survey-based approach to …

The Relationship Between Phone Usage, Activity Participation, And Hand Strength, Debra Gibbs, Will Best, Raegan Adams, Amanda Finke, Rachel Pierce, Salem Swallows, Alisha Yoo

SPARK Symposium Presentations

Smartphone use among university students in the United States is steadily increasing. Longer duration of smartphone use has been associated with increased risk of smartphone addiction, reduced musculoskeletal strength, and engagement in meaningful activities. While prior research has examined these variables separately, limited evidence exists on the associations between smartphone use, hand grip and pinch strength, and extracurricular and leisure activities among U.S. university students. To address this gap, a correlational study was conducted using the Spearman rank correlation to analyze the relationship between phone use, activity participation, and hand strength. A Qualtrics survey including demographic information, phone usage, and …


Crisis Communication In The Influencer Era: A Crisis Response Analysis Of Poppi And Alani Nu, Meredith E. Staley Jan 2026

Crisis Communication In The Influencer Era: A Crisis Response Analysis Of Poppi And Alani Nu, Meredith E. Staley

Honors College Theses

As social media continues to reshape modern public relations practice, beverage brands like Alani Nu and Poppi offer relevant examples of influencer-driven communication and crisis response. This honors thesis compares and contrasts these brands following two major crises: Poppi’s influencer vending machine campaign and the health concerns and backlash surrounding Alani Nu’s energy drinks. Despite the well-known prevalence of these brands, there is little scholarly research examining their crisis communication strategies. Guided by Situational Crisis Communication Theory, this study uses a combination of social and news media content analysis to evaluate how each brand responded to its respective crisis. Each …


No Screens Before Two: How First-Time Australian Parents Negotiate Enduring Digital Media Guidelines, Stephanie C. Milford, Emma Jayakumar, Harrison W. See, Lelia Green Jan 2026

No Screens Before Two: How First-Time Australian Parents Negotiate Enduring Digital Media Guidelines, Stephanie C. Milford, Emma Jayakumar, Harrison W. See, Lelia Green

Research outputs 2022 to 2026

Digital parenting guidance often fails to reflect early caregiving realities, particularly for first-time parents navigating screentime. Although professional guidelines have shifted from rigid time limits toward co-engagement and content quality, these shifts are inconsistently communicated and poorly absorbed into public discourse. Meanwhile, technopanic narratives fuel confusion, guilt, and social judgement. While some studies link extended screen use with adverse outcomes, we examine how correlational findings become blanket prescriptions in early caregiving. Drawing on two interview rounds and three focus groups with 23 Australian first-time parents of children aged birth-to-four, and informed by a socio-ecological approach, we explore how parents interpret …

Modeling Joint Visual Attention In Naturalistic Dyadic Interactions, Kuushini Thennakoon, Yasasi Abeysinghe, Bhanuka Mahanama, Vikas Ashok, Sampath Jayarathna

Computer Science Faculty Publications

Joint visual attention (JVA) provides important insight into how individuals coordinate attention during social interaction. Egocentric eye tracking enables the study of JVA in natural, multi-user settings. This work presents a multi-stage framework to identify and analyze JVA using egocentric video and gaze data. The approach consists of three steps: spatiotemporal tube-based visual similarity, gaze-guided object detection, and attention pattern analysis using the ambient–focal coefficient K. Results show that object-focused collaborative activities exhibit high JVA, with object detection capturing higher joint attention than visual similarity, whereas conversation-based or independent activities show lower and more fragmented joint attention. Analysis of K …
