Item Efectos de los casos de corrupción política en la agenda de probidad y transparencia en el estado chileno en el período 2000 - 2009(Universidad del Desarrollo, Facultad de Gobierno, 2019) Risso Dawidowicz, Cristóbal Andrés; Drobny, SammyItem The Ecosystems of Simple and Complex Societies: Social and Geographical Dynamics(2018) Guzmán, Ricardo Andrés; Drobny, Sammy; Rodríguez-Sickert, CarlosWe present a spatial agent-based model of the emergence and proliferation of premodern complex societies in an isolated region initially inhabited by simple societies. At the intrasocietal level, the model integrates scalar stress, social fission, sociocultural evolution, societal collapse, and Malthusian-Ricardian demographic dynamics. At the geographical level, the model includes warfare for territory and captives, territorial division due to social conflict, and territorial disintegration due to collapse. We found that a single variable – slow, continuous progress in intensive agriculture – drives the social and geographical dynamics. Consistent with the archaeological and historical record, the model produced three consecutive “eras”: During the first era, simple societies dominate the region. They use extensive food production methods. Small complex societies of intensive agriculturists emerge intermittently in the core land, where intensification is feasible. Shortly after, they collapse or are annihilated by local simple societies. During the second era, some complex societies avert early collapse and annihilation. They expand by conquest. At all times, they coexist with simple societies. Some complex societies are destroyed in war; others collapse. From time to time, complex societies collapse en masse. During the third era, there are no more mass collapses. Complex societies slowly expand until they dominate the core land. Simple societies take refuge in the marginal land, where intensification is infeasible. Simple and complex societies coexist, separated by a moving frontier. In an ebb and flow, complex societies expand to the marginal land and withdraw to the core land. The results of the simulations are qualitatively consistent with prehistorical and historical case studies. The model replicates the progression from simple to more complex societies, and explains why that progression happened in fits and starts.
