Interpretable Multimodal Learning For Integrating Neuroimaging And Genetic Data In Alzheimer’S Disease, Kun Zhao, Siyuan Dai, Yingying Zhang, Guodong Liu, Pengfei Gu, Chenghua Lin, Paul M. Thompson, Alex D. Leow, Heng Huang, Haoteng Tang

Computer Science Faculty Publications

Introduction: Early detection of Alzheimer's disease (AD) requires models that combine brain structure changes with genetic risk, but existing methods struggle to align these different data types.

Methods: We present R-GenIMA, an interpretable multimodal large language model that pairs a region-of-interest vision transformer with genetic prompting to jointly analyze structural MRI and single nucleotide polymorphisms (SNPs). Each brain region becomes a visual token and SNP profiles are encoded as structured text, letting the model link regional atrophy to genetic factors through cross-modal attention. Tested on the ADNI cohort, R-GenIMA performs well in classifying four groups: normal cognition, subjective memory concerns, …

Austronauts 3u Cubesat Space Weather Payloads Proposal, Tiana Pendray

Small Satellite Conference

CubeSats are becoming increasingly prominent due to their accessibility, affordability and versatility. An emerging field of satellite application is the monitoring of ionospheric space weather, made possible by sensitive instruments that collect data on plasma potential, temperature and ion density. These parameters vary due to changing solar activity in the form of Coronal Mass Ejections (CMEs) and solar flares, which can have severe impacts on satellite navigation systems, radio communication networks and orbital estimations. The AUStronauts team at the University of New South Wales is developing a 3U CubeSat with two space weather payloads – an Electrodynamic Tether (EDT) and …

Bit-Flip Sensitivity And Selective Fp32 Protection For Onboard Neural Networks In Flight Software: In-Place Secded Healing Of An Fp32 Weight Buffer Inside Nasa Cfs, Ryan Goodman, Carson Cramer, Braden Eichmeier, Emily Gerber, Christopher Roscoe

Small Satellite Conference

Smallsat missions increasingly deploy neural networks on COTS processors. In orbit, a charged particle striking such a device can flip a single bit of memory, a single event upset (SEU). An upset in a network weight raises no fault condition: the network continues to run, returns incorrect values, and the control loop downstream acts on them. 

The standard cFS response to memory corruption is process restart, which interrupts service and discards runtime state.

Multi-Phase Guidance And Control For Small Satellite Docking Via Deep Reinforcement Learning, Tanner Gill, Greg Furlich, Nisar Ahmed

Small Satellite Conference

As interest in small satellite Rendezvous, Proximity Operations, and Docking (RPOD) grows, so does the need for high-level autonomy in space systems. Current systems relying on constrained hardware and ground-in-the-loop decision-making are ill-equipped for the evolving, contested space domain. Recent research on autonomous spacecraft guidance and control has moved beyond established optimal control and trajectory optimization methods to incorporate Reinforcement Learning (RL), though these efforts have predominantly focused on a single operational phase. This research advances small satellite docking autonomy by formulating the reference scenario as a Hierarchical Markov Decision Process (H-MDP), expanding the scope of the learned guidance and …

F Prime To Flight Faster: Hardware-In-The-Loop Continuous Integration For Accelerated Cubesat Development, Nate Gay, Saidi Adams, Michael Pham

Small Satellite Conference

Flight software teams iterate quickly in development and then slow down at integration, because the software must be validated against real hardware that is itself still changing. 

Bench testing is manual, intermittent, and happens late. Defects surface days after the commit that caused them, once the context is gone and the change has been built on.

Promoting Assured Formation Flight Autonomy Onboard Resource Constrained Systems, Ryan Johnson, Maggie Michelsen, Jackson Gardner, Mario Harper, Charles Swenson, Jackson Kulik, Shawn Jones

Small Satellite Conference

Autonomously determining fuel-optimal, formation-keeping trajectories for small spacecraft operating in formation flight is often limited by available processing power. Because SmallSat missions are constrained by size, weight, and power (SWaP), field-programmable gate arrays (FPGAs) are an attractive option for onboard computing. Traditional formation-keeping relies on convex optimization to solve for fuel-optimal burns and burn times; however, implementing these solvers on FPGAs is challenging due to limited board resources.

To address the need for fast, reliable trajectory planning onboard space vehicles, we investigate leveraging machine learning to reduce computational cost for real-time, onboard execution. We propose using a deep neural network …

Squidsat: A Modular, Open-Source 3u Cubesat Bus For Low-Cost Cubesat Missions, Aaron Bournias, Joseph Dukowitz, Mark Jaber, Tyler Field, Micah Nguyen, Koowum Joshi, Noah Campos, Daphne Riordan, Ryan La Ra, Jonathan Luse, Joshua Sink, Tyler Nielsen, Ricardo Ontivaros, Michael Goryll, Joe Dubois

Small Satellite Conference

CubeSat launches continue to increase yearly, yet over 51% of missions from 2002–2016 failed. Primary faults were often due to power, mechanical, or design issues. Costs still remain high in a market driven by expensive flight-heritage hardware with proprietary designs. In order to counteract such costly practice, Sun Devil Satellite Lab (SDSL) at ASU has developed an open-source, modular 3U CubeSat bus built for low cost reliability. Unlike other bus architectures, SquidSat distributes control across independent microcontrollers linked via a CAN bus. CAN is commanded by the OBC but is capable of independent operation for fault isolation and easier testing. …

Artificial Intelligence (Ai) As A Communication Pedagogy Mega-Risk, Deanna Sellnow

Journal of Communication Pedagogy

With the ever-expanding capabilities offered by artificial intelligence (AI), communication teachers, scholars, and practitioners are currently in the midst of heated debates about whether and how to use AI both in our classrooms and in our research. This essay contextualizes the debate by describing generative AI as a technological mega-risk that, if left unchecked, may manifest into a mega-crisis impacting people and planet in extraordinarily harmful ways. Consequently, I argue that it is our responsibility as instructional communication scholars, communication education teachers, and communication pedagogy experts to discover strategies for harnessing its power to manage the potential threats posed by …

The Mundanity Of Ai, David Westerman, Nicholas Bowman

Journal of Communication Pedagogy

The emergence of ChatGPT in late 2022 brought with it a reemergence of utopian and dystopian claims of the grand power of AI. Yet, AI has failed to achieve such lofty expectations and instead has trended toward far more banal, yet productive, tasks and goals. We argue that this mundanity is precisely what makes AI an important technology, and moreover, those “mundane tasks” are central to communication education. Specifically, we advocate for a decreased focus on the hyped ideas of AI that dominate popular discourse and obfuscate more reasoned analyses of AI as communication technology. A more pragmatic focus should …

Ai Didn’T Break Our Teaching, It Revealed Our Teaching, Michael G. Strawser

Journal of Communication Pedagogy

The rapid emergence of generative artificial intelligence (AI) has prompted widespread concern about academic integrity, student learning, and the future of higher education. While AI is often framed as a disruptive force, this commentary argues that many of the challenges attributed to AI predate the technology itself. Rather than creating new problems, AI has exposed long-standing tensions embedded within higher education and communication pedagogy. Three tensions that have become increasingly visible in the presence of AI are identified: learning versus completion, efficiency versus depth, and human connection versus algorithmic mediation. First, AI challenges assumptions that the successful completion of assignments …

Teaching Ai Through Communication: Rethinking Evidence, Interaction, And Learning, Chad Edwards, Matthew J. A. Craig, Varun Rijhwani, Habeeb Abdulrauf

Journal of Communication Pedagogy

This conceptual essay advances a central claim: Communication pedagogy is increasingly engaged in teaching AI through communicative interaction. Moving beyond the familiar distinctions between teaching with AI and teaching about AI, it argues that classrooms function as sites where AI communication is shaped through prompting, critique, revision, and ethical evaluation. Drawing on human–machine communication scholarship, the essay reconceptualizes evidence of learning as visible in students’ reasoning, justification, and contextual adaptation rather than in polished outputs. By foregrounding relational engagement, transparency, and communicative judgment, it positions teaching AI as a defining pedagogical task in AI-mediated educational environments.

How To Blow Up An Ai Data Center, Tyler Rife

Journal of Communication Pedagogy

This essay advocates a critical pedagogical orientation to AI guided by a politics of refusal. I pursue this advocacy by, first, showing how the social and environmental harms of AI technology outweigh any promises to its social good and then, second, locating resonances between our contemporary technological situation and similar inflection points in the histories of labor organizing and environmental justice activism. Together, these material implications of the emergent technology help form a pedagogical framework for how communication educators can advance critical literacy about AI in the classroom as a constructive counterpoint to its uncritical adoption in the learning process. …

Ai And Agency: Policy As Problem Posing In The Introductory Communication Studies Classroom, Deanna L. Fassett, Nancy Park

Journal of Communication Pedagogy

This forum essay examines artificial-intelligence policy in introductory communication courses through the lens of critical communication pedagogy. It identifies a tension between institutional pressures for readily enforceable, surveillance-oriented AI policies and relational approaches that support instructors’ and students’ long-term agency. Drawing on problem-posing pedagogy, the authors argue that prepackaged policies can position teaching assistants as policy enforcers rather than reflective educators. They propose collaborative policy development as a means of fostering dialogue, ethical discernment, human connection, and critical engagement with AI’s role in communication education.

When They Automate, We Conversate: Tensions On Ai In Communication Pedagogy, Kyle Vareberg, Meggie Mapes

Journal of Communication Pedagogy

This forum introduction invites communication pedagogues to move beyond binary debates about whether to use or resist artificial intelligence. It frames AI as a set of enduring pedagogical, ethical, institutional, environmental, and communicative tensions that require critical inquiry rather than premature certainty. The forum’s contributors examine questions of agency, policy, relational communication, infrastructure, learning processes, and risk management, positioning communication pedagogy as essential to helping students and educators engage AI with rigor, curiosity, and human-centered intentionality.

From Weaponized Doubt To Educated Doubt: Critical Communication Pedagogy’S Deconstruction Of Post-Truth, David H. Kahl Jr.

Journal of Communication Pedagogy

Powerful and hegemonic entities in society disseminate post-truth messages in order to gain wealth, maintain power, and increase control. Unsuspecting individuals encounter these inimical messages and often find themselves experiencing difficulty discerning fact from fiction because they are largely unprepared to deal with this type of deceitful persuasion. Specifically, unethically utilizing principles of communication pedagogy through what I deem the post-truth process of weaponizing doubt, hegemonic actors deter people from responding and taking action. Because of this, a critical communication pedagogy is needed, utilizing dialogue to prebunk and debunk the process to help people learn to develop educated doubt that …

Speaking In Color: Code-Meshing Against Standard Language Ideology In The Public Speaking Classroom, Darrion A. Walker

Journal of Communication Pedagogy

Public speaking courses do more than teach presentation skills; they also teach students which voices count as credible. In Predominantly White Institutions (PWIs), instructional norms tied to standard language ideology position standardized English as the unmarked benchmark of professional communication. For students who speak African American Language (AAL) or other culturally informed language varieties, this creates a double bind: conform linguistically or risk being penalized for rhetorical authenticity. This reflective essay identifies the double bind as an underexamined problem in communication pedagogy and suggests that code-meshing—the intentional blending of multiple language varieties within a single communicative act—offers a more equitable, …

Creating Safe(R) Classrooms: Trauma-Informed Teaching Practices In Higher Education, Shannon Pappas, Nolan Bowers, Lili R. Romann

Journal of Communication Pedagogy

Trauma is a public health issue, with effects being increasingly harmful for adolescents. While instructors cannot control how students respond to trauma, they can work to create traumainformed teaching practices to support student learning and safety. Based on the principles of trauma-informed pedagogy, this manuscript details how safety, trustworthiness and transparency, choice, collaboration, and empowerment can be implemented in higher education communication courses. Additionally, a sixth principle, responding to the current climate, is introduced. Currently, instructors are grappling with supporting vulnerable students and answering to those in power. These practices offer insights into classroom adaptations to assist instructors in these …

Community Problems Need Community Solutions: Feminist Collaboration Across Campuses To Create Transformative Outcomes Through Community Engaged Learning, Elizabeth Wilhoit Larson, Jasmine R. Linabary, Ziyu Long, Kylie J. Johnson

Journal of Communication Pedagogy

This study presents a multi-institutional engaged pedagogy project responding to college food insecurity that involved partnerships among students, instructors, and campus food pantries from three U.S. universities. Through analysis of pre- and post-class surveys, class assignments, and instructor and community partner reflections, we argue that our feminist collaborative approach resulted in transformative outcomes in three areas: (a) heads, as the collaboration enabled critical understandings of food insecurity and how to combat it; (b) hearts, as the collaboration fostered a culture of care and (re)ignited shared passion in doing change work, and (c) hands, as the collaboration inspired actions to address …

Decolonizing Communication Pedagogy: Toward An Afro-Rhetorical Framework, Lionnell Smith

Journal of Communication Pedagogy

This essay introduces Afro-rhetorical pedagogy as a decolonial framework for communication pedagogy. Building on Adam Key’s 2022 call for an Applied Africana Studies framework for public speaking pedagogy, this essay conceptualizes Afro-rhetorical pedagogy grounded in Afrocentric thought and African communication theory. Through a close reading of Molefi Kete Asante’s 2011 address on African curriculum, this essay establishes three foundational principles for Afro-rhetorical pedagogy: (a) epistemological agency, (b) decolonized knowledge production, and (c) institutional reconstruction. This pedagogical framework addresses communication education’s reproduction of white cultural hegemony by promoting African-centered principles, practices, and precepts that reposition communication pedagogy as a more liberatory …

Meeting Rhetorical And Relational Goals In Online Higher Education: Insights From A South African Case Study, Rentia Du Plessis, Diana Breshears, Luzelle Naudé Prof

Journal of Communication Pedagogy

This qualitative study examines the degree to which synchronous and asynchronous online learning platforms both supported and constrained the achievement of rhetorical and relational goals in a resource-constrained South African higher education context. As online teaching practices persist in the post-COVID era, understanding how to design pedagogically sound online environments is increasingly important, particularly in the Global South where cost, access, and connectivity pose significant constraints. Drawing on the Rhetorical and Relational Goals Theory (RRGT; Mottet et al., 2006) and Kaufmann et al.’s (2016) online learning climate dimensions, the study analyzes undergraduate students’ perceptions of Blackboard Collaborate, PowerPoint voice-overs, WhatsApp, …

The Co-Educators Framework: An Illustrative Account Of Shared Pedagogical Practice And Inclusive Teaching In A Large-Enrollment Communication Course, Divya S, Man Luo, Jisha Jacob, Shahla Shahnaz Dyuti, Victoria Michelle Main

Journal of Communication Pedagogy

Large-enrollment courses present structural challenges to inclusive and relational pedagogy, particularly when instructional labor is shared across teaching teams that include graduate teaching assistants (GTAs). This study examines inclusive teaching as a communicative and practical process enacted through co-education, the coordinated instructional work of faculty and GTAs. Using a diary-based reflexive design, four doctoral GTAs contributed teaching journals across one semester of an undergraduate Communication Theory course. Reflexive thematic analysis identified four themes: collaborative course design, communication as pedagogical infrastructure, equitable assessment, and reflexive care. The study offers the Co-Educators Framework as an illustrative account of how shared, communicative pedagogical …

Exploring Power In The Classroom Through The Lens Of Relational Power, Aubree A. Herman, Narissra Maria Punyanunt-Carter Phd

Journal of Communication Pedagogy

This study explores how French and Raven’s relational power model shapes student communication in higher education. Through a survey of 530 undergraduates, the research investigates how TA age and gender, and student gender, impact student perceptions of power. Results indicate that TA gender and age impact student perceptions of referent power, but not expert power; however, expert and referent power emerged as the strongest predictors of course satisfaction and intention to take future courses, while coercive power negatively predicted both outcomes. These findings underscore the importance of expertise and interpersonal interaction in the TA–student relationship and suggest that French and …

Caveats For The Forensic Use Of The Pcl-R With Antisocial And Psychopathic Women, Carl B. Gacono, Ted B. Cunliffe, Jason M. Smith, Enna E. Taylor

Archives of Assessment Psychology

Special considerations are necessary when assessing antisocial and psychopathic women.  Evident throughout the evaluation process (Cunliffe et al., 2016; Gacono, 2016; Gacono & Meloy, 1994; Gacono & Smith, 2021; Smith et al., 2014, 2021; Taylor, 2015), gender differences suggest the need for modified approaches, shape the transference/countertransference between examinee and examiner, and affect the administration, scoring, and interpretation of psychological tests. In this article we summarize Rorschach findings that support the underlying dynamics in antisocial and psychopathic women, discuss the unique aspects of evaluating the female psychopath, and present eight PCL-R items in need of modification for assessing women.
