study of collective actions is related to some of the most important issues in contemporary sociology such as cooperation, collective decision making, emergence of social norms etc. this paper in four steps presents a framework for studying collective actions. these steps are related to characteristics of collective actions (cooperation and common good), factors effecting the emergence of colle...

Due to the lack of an integral study about Cognitive Maps that focus on the causal phenomenon, this work introduces the underlying concepts towards a Holistic Conceptual Model, enhanced by a profile of several versions. We illustrate this by their application to Web-based Education Systems. From the causal perspective, Cognitive Maps depict and simulate the systems dynamics based upon qualitati...

We introduce a new familiy of random compact metric spaces Sα for α∈(1,2), which we call stable shredded spheres. They are constructed from excursions α-stable Lévy processes on [0,1] possessing no negative jumps. Informally, viewing the graph excursion in plane, each jump process is “cut open” and replaced by circle, then all points at equal height, not separated jump, identified. show that sp...

We study m-transportability, a generalization of transportability, which offers a license to use causal information elicited from experiments and observations in m ≥ 1 source environments to estimate a causal effect in a given target environment. We provide a novel characterization of mtransportability that directly exploits the completeness of docalculus to obtain the necessary and sufficient ...

We numerically demonstrate that collective bifurcations in two-dimensional lattices of locally coupled logistic maps share most of the defining features of equilibrium second-order phase transitions. Our simulations suggest that these transitions between distinct collective dynamical regimes belong to the universality class of Miller and Huse model with synchronous update [Marcq et al., Phys. R...

The authors outline a cognitive and computational account of causal learning in children. They propose that children use specialized cognitive systems that allow them to recover an accurate "causal map" of the world: an abstract, coherent, learned representation of the causal relations among events. This kind of knowledge can be perspicuously understood in terms of the formalism of directed gra...
