Title:
Can conversation change minds: applying mental models to the UC Davis Adaptive Rangeland Management study
Abstract:
This project combines networks of mental models and conversation dynamics to understand collaboration and deliberation in a small group. We brought interested stakeholders (ranchers, conservationists, and government rangeland managers) to visit a piece of UC Davis rangeland and develop a management strategy. Prior to group discussion, we surveyed 4 groups of respondents (a homogenous group from each category of ranchers, conservationists, and government rangeland managers as well as one mixed group) about the management decisions they would make. In particular, we were interested in how these respondents linked the methods they would use to the goals they set. We thus have bipartite networks for each individual respondent where the tie indicates that a given method should be used to achieve a given goal. After the group discussion, we then asked each individual to make any changes they felt were appropriate to their network of responses about goals and methods that they had given before discussion. We use Butts’ Informant Accuracy Model (2003) to look at the cultural consensus within groups and compare it to change over time. We find the most change in linkages between goals and methods (rather than new goals and methods), and we find in all cases that individuals do indeed change to be more like the rest of the group.
Speaker Bio:
Lorien Jasny is a computational social scientist in the Department of Politics at the University of Exeter. Her work focuses on questions of public involvement and engagement in environmental decision making. In my research I explore two related themes – how the structure and dynamics of inter-organizational networks affect policy change, and how the structure and dynamics of belief networks affect behavioral change. Substantively, she studies how people try to bring about societal change in response to political and environmental concerns. Methodologically, the need to grapple with these often complex phenomena requires the use and development of techniques for handling large, dynamic, and relational datasets.

WED@NICO SEMINAR: Julio M. Ottino, Northwestern University "From Clocks to Clouds: The Complexity Revolution"
Northwestern Institute on Complex Systems (NICO)
12:00 PM
//
Lower Level, Chambers Hall
Details
Speaker:
Julio M. Ottino, Walter P. Murphy Professor of Chemical and Biological Engineering, McCormick School of Engineering, Northwestern University
Title:
From Clocks to Clouds: The Complexity Revolution: How Scientific Breakthroughs Reshaped Reality and Our Place Within It
Abstract:
For three centuries, Western thought was guided by a Newtonian worldview: the universe as a vast clock, predictable and controllable. That vision has unraveled. Scientific revolutions—from relativity and quantum mechanics to evolution, game theory, and complexity science—have revealed a world of uncertainty, emergence, and creative interconnection. We now inhabit a “cloud world,” where relationships matter more than parts, and uncertainty is not ignorance but potential. This talk traces the transformation from clocks to complexity, showing how these revolutions reshape our understanding of reality and what it means to navigate knowledge, organizations, and society in turbulent times.
Speaker Bio:
Julio M. Ottino is an engineering scientist recognized for his work in fluid dynamics, chaos and nonlinear dynamics, complex systems, and especially mixing. He was born in La Plata, Argentina and grew up with twin interests in the physical sciences and visual arts. He obtained his first degree at the University of La Plata, in Argentina, before receiving a PhD in chemical engineering from the University of Minnesota. He is currently at the McCormick School of Engineering and Applied Science in Northwestern University where he holds the titles of Robert R. McCormick Institute Professor and Walter P. Murphy Professor of Chemical and Biological Engineering. He is also a professor of Management and Organizations at Kellogg School of Management. He was the co-founder and director of the Northwestern Institute on Complex Systems (NICO) and the author of the Kinematics of Mixing: Stretching, Chaos, and Transport (Cambridge University Press 1989) and The Nexus, Augmented Thinking for a Complex World, with Bruce Mau (MIT Press, 2022).

WED@NICO SEMINAR: Blaise Aguera y Arcas, Google "Symbiogenesis, Computational Parallelism, and Complexity in Evolution"
Northwestern Institute on Complex Systems (NICO)
12:00 PM
//
Lower Level, Chambers Hall
Details
Speaker:
Blaise Agüera y Arcas, VP/Fellow, CTO of Technology & Society, Google
Title:
Symbiogenesis, Computational Parallelism, and Complexity in Evolution
Abstract:
Symbiogenesis-- the fusion of formerly independent self-replicating entities into a larger self-replicating entity-- is proposed as the driving force behind evolution's "arrow of time" toward ever-increasing complexity. We'll explore an Artificial Life system as a minimal motivating example, then discuss the implications for biological evolution beyond the "standard" accounts of Major Evolutionary Transitions and "intelligence explosions" in brainy species. Energetic and computational implications will also be addressed.
Speaker Bio:
Blaise Agüera y Arcas is a VP and Fellow at Google, where he is the CTO of Technology & Society and founder of Paradigms of Intelligence (Pi). Pi is an organization working on fundamental research in AI and related fields, especially the foundations of neural computing, active inference, sociality, evolution, and Artificial Life.
In 2008, Blaise was awarded MIT’s TR35 prize. During his tenure at Google, Blaise has innovated on-device machine learning for Android and Pixel; invented Federated Learning, an approach to decentralized model training that avoids sharing private data; and founded the Artists + Machine Intelligence program.
An External Professor at Santa Fe Institute and a frequent public speaker, Blaise has given multiple TED talks and keynoted NeurIPS. He has also authored numerous papers, essays, op-eds, and chapters, as well as two previous books, Who Are We Now? and Ubi Sunt. His most recent book, What Is Life?, is part 1 of the larger book What Is Intelligence?, forthcoming from Antikythera and MIT Press in September 2025.
