✍️ ¡Nuevo artículo! Issa Luna Pla, @jrncarlock.bsky.social y Harald_Waxecker muestran por qué las redes criminales deben investigarse como sistemas, no como casos aislados. Enfrentarlas exige análisis de relaciones y acciones contra actores centrales.

In complex systems, linear tools fail against nonlinear phenomena. You can’t fight smoke with a sword, nor bite water with your teeth—because complexity dissolves brute force. It demands sensitivity, adaptability, and systemic understanding. #complexity

Super excited about our new paper on mobility that's out in Nature Human Behavior www.nature.com/articles/s41...
I love this paper for many reasons, but one is that we find beautiful 1/x power-law that spans 6 orders of magnitude hidden within the "ugly" distribution raw mobility data.

What is complexity? Complex Systems made of many interacting units display "emergence", i.e. global properties that cannot be reduced to the properties of the units. A new idea? WM Wheeler was one of the advocates of emergence, back in 1927 @sfiscience.bsky.social
