Critical Digital Studies, DH, and Ethical Collaboration

Liz Grumbach & Sarah Florini (ASU)

Critical digital studies and digital humanities share an investment in interrogating and disrupting systems of power and oppression. Yet, they are rarely in dialogue. In their talk, Liz Grumbach and Sarah Florini will discuss projects they are undertaking that put these disciplines in conversation. Undertaken in cooperation with the Lincoln Center for Applied Ethics under the broad umbrella of “Technologies of Domination,” these ongoing projects include a two-day design lab workshop on technology and oppression, a collaborative research endeavor with TikTok creators, and a de(con)structive approaches to whiteness and UX. Grumbach and Florini demonstrate how critical digital studies and digital humanities can form a generative partnership grounded in ethics of collaboration and community.

Liz Grumbach is the Program Manager for Digital Humanities and Research for the Lincoln Center for Applied Ethics, an organization committed to exploring co-creative and participatory strategies for ethical technological innovation, at Arizona State University. Her work has been published in scholarly publications such as Digital Humanities Quarterly, Scholarly Research and Communication, Digital Scholarship in the Humanities, and the Journal on Computing and Cultural Heritage.

Sarah Florini is an Associate Professor of Film and Media Studies in the Department of English at Arizona State University. Her work combines critical digital studies, critical race theory, and African American and Black Studies to explore the intersection of race and technology.

 Abstract: Statistical network analysis typically deals with inference concerning various parameters of an observed network. In several applications, especially those from social sciences, behavioral information concerning groups of subjects are observed. Over the past century a number of descriptive statistics have been developed to infer network structure from such data. However, these measures lack a generating mechanism that links the inferred network structure to the observed groups. In this talk, we present a model-based approach called the hub model, which belongs to a family of Bernoulli mixture models. We further present theoretical results on model identifiability, a notoriously difficult problem in Bernoulli mixture models, and estimation consistency.

AbstractRecent genetic studies have identified genes related to specific human diseases or traits. Besides marginal analysis of individual genes, analyzing biologically meaningful gene pathways, i.e., networks with nodes being genes and edges characterizing the presence/absence of the gene-gene interactions, may yield valuable insights. Identifying gene pathways that differ between conditions can be formulated as a multivariate hypothesis testing problem, but existing approaches handle the gene-gene correlations in inefficient ways, leading to inflated type I error rate and/or compromised power. In this paper, we propose a Hotelling's T2-type statistic, named the T2-DAG test, which efficiently leverages the edge information in the gene pathway through a linear structural equation model. We investigate asymptotic properties of the T2-DAG test under pertinent assumptions and compare the T2-DAG test with six existing methods under various simulation settings. We also apply the T2-DAG test to a lung cancer gene expression data set, and identity several interesting gene pathways that are relevant to different stages of lung cancer.

Abstract: I will discuss our vision for the NSF National AI Institute for Student-AI Teaming. The Institute will: (1) develop the theories, Artificial Intelligence (AI) technologies, and know-how for creating next-generation collaborative learning environments composed of diverse students, teachers, and AI; (2) grow a diverse workforce of future AI researchers and practitioners by engaging 5,000 middle/high school students in innovative AI education through AI-enabled pedagogies; (3) serve as a national nexus point for empowering diverse stakeholders to engage in responsible co-design of student-AI collaborative technologies. This national institute brings together a geographically distributed team of researchers from nine Universities with partners from academia, K-12 school districts, and industry to address the central challenge of how to promote deep conceptual learning via rich socio-collaborative learning experiences for all students. To meet this challenge, the Institu te will reframe the role of AI in education, moving towards a future where AI is viewed as a social, collaborative partner that help students work and learn more effectively, engagingly, and equitably, while helping educators focus on what they do best: inspiring and teaching students. The Institute will adopt responsible innovation and polycultural approaches for developing ethical AI technologies by integrating foundational and use-inspired AI research across more than 12 interdisciplinary research areas spanning the computing, learning, cognitive and affective sciences. The Institute aims to lead the nation towards a future where all students routinely participate in rich and rewarding AI-enabled collaborative learning experiences that scale across a large number of classrooms, resulting in deeper student engagement and persistence in STEM, more inclusive classroom cultures, and significant improvements in learning outcomes.

Rescorla-Wagner Models with Dynamic Attention and Ensembles

Abstract: The Rescorla-Wagner (R-W) model is a discrete time stochastic process frequently used to model human learning, wherein an agent learns associations between cues and subsequent responses by dynamically updating cue associative strengths proportionally to a prediction error. We characterize the 'curse of dimensionality' for the R-W model and propose a method to overcome this limitation that uses dynamic attention to learn sparse signals. Given the difficulty in selecting features for prediction, dynamic attention faces challenges beyond those faced by the R-W model. Our new framework not only satisfies a constraint on the number of attended cues, it also performs better than the R-W model on a number of natural learning tasks, can correctly infers associative strengths, and focuses attention on predictive cues while ignoring uninformative cues.
Speaker Bio: Joel Nishimura is an Assistant Professor of Applied Mathematics at the West campus of ASU. He conducts research in several areas inside of and in the overlap between network science, dynamical systems and mathematical biology. A unifying feature of these systems is that simple rules can create complex behaviors and/or structures. He received his doctorate from Cornell University in 2013.

Whom we include and how they succeed

Presentation: “Whom we include and how they succeed”: A role for inclusion and equity in data-informed learning engineering
Tom Fikes
Speaker: Dr. Tom Fikes, Senior Researcher and Director of Research for the Action Lab at Arizona State University
Time: 2-3pm MST, October 14, 2020 
Abstract: In this talk, I will begin with some definitions of “data science” and “learning engineering” – less for the purpose of arguing for the adoption of particular definitions, and more to begin a conversation about what the Action Lab is and does, with a goal of beginning a mutually beneficial research collaboration with B2C2 members around these topics in order to create even better learning environments for our ASU students (and particularly of our SSBS and New College students).  I will argue that data science, learning engineering, and other similar useful professional identifications are structurally defined, but are always (if implicitly) embedded within functional contexts; and that social transformation requires a deep awareness on the part of data scientists, learning engineers, and allied agents and actors as to the nature of those functional contexts. Indeed, given the inevitable competition between functional contexts, we must go beyond merely being aware of them to cultivating and sustaining them. The second (and hopefully longer) portion of the talk will be around several data visualizations that highlight student learning, persistence, and retention at ASU. These visualizations will allow me to argue for a functional context that extends beyond “success for the average learner” (or for the institution) to one of equity, inclusion, and social justice. Not surprisingly, given the title, I will situate this within the context of the ASU charter and its language of inclusion and success.
Speaker Bio: Tom Fikes is Senior Researcher and Director of Research for the Action Lab at Arizona State University. He completed his Ph.D. at U.C. Santa Barbara where he studied cognitive psychology and cognitive neuroscience. Following postdoctoral work in mathematical modeling and cognitive science at Indiana University, he served teaching, research, and faculty administrative roles as professor of psychology and neuroscience at the University of Puget Sound in Tacoma, WA and Westmont College in Santa Barbara, CA. His current work centers on plying data science, modeling, visualization, and design thinking toward increased inclusivity, equity, and excellence in student learning.
