Exact Scaling Theory of Social Tipping Phenomena in Finite Populations
Bianca Y. S. Ishikawa, José F. Fontanari
Granovetter's threshold model provides a classical framework for social mobilization, where collective action spreads through cascades as individuals join once movement size reache…
Revisiting the non-equilibrium phase transitions of the continuous-trait Axelrod model
Sandro M. Reia, Paulo R. A. Campos, José F. Fontanari
We investigate the non-equilibrium phase transitions of the continuous-trait Axelrod model, an agent-based framework where individual culture is represented by a vector of cont…
Exact Solution of Granovetter's Threshold Model for a Finite Population
José F. Fontanari
The Granovetter threshold model formalizes collective behavior by assuming that individual agents face a binary decision to join a movement, doing so only when the number of alread…
The Same Problem by Different Names: Unifying Regression Dilution and Regression to the Mean
José F. Fontanari, Mauro Santos
Regression to the Mean (RTM) and Regression Dilution are traditionally treated as unrelated issues in the clinical and ecological literatures. In this work, we demonstrate that wit…
When correcting for regression to the mean is worse than no correction at all
José F. Fontanari, José F. Fontanari, Mauro Santos
The ubiquitous regression to the mean (RTM) effect complicates statistical inference regarding the relationship between baseline levels of a biological variable and its subsequent…
Competitive Social Mobilization in Threshold Models of Collective Action
Bianca Y. S. Ishikawa, José F. Fontanari
Social mobilization often fails not for a lack of collective interest, but because of fierce competition between rival movements for the same limited pool of participants. We gener…
