Prof. David LANE, University of Modena & Reggio Emilia, Italy. For a long time, the idea of novelty was generally regarded with great suspicion; in the last few centuries, it is increasingly viewed in a favourable light, so much so that it seem

Simulating the dynamics of systems of cities, the Simpop models

Jun 11th, 2010 52m 20s

Prof. Lena SANDERS, CNRS, Paris, France. Cities evolve at different rhythms, some growing, other stagnating or even declining. The hypothesis is that these differences are the result of different abilities to valorise a position in a system of

The complexity of structure, strategy and decision making

Jun 11th, 2010 49m 45s

Prof. Peter ALLEN, Cranfield University, United Kingdom. Many spatial models are really ‘fitted descriptions’ of spatial changes that have occurred. In order to have a deeper and possibly more long term understanding of what is going on, or may

Trust, Recommender Systems and Coalitions in Social Networks

Jun 10th, 2010 1h 7m

Prof. Stefano BATTISTON, System Design, ETH Zurich, Switzerland. We propose a novel trust metric for social networks which is suitable for application to recommender systems. It is personalised and dynamic, and allows to compute the indirect tr

Economic inequalities spatial patterns in a sustainable world, a complex systems approach

Jun 10th, 2010 48m 2s

Prof. Gerard WEISBUCH, Ecole Normale Supérieure Paris, France. We discuss the possible World patterns of economic activity after the transition to a sustainable and stationary economy. Our main concern is the economy of energy, most probably th

Geo-simulations of urban phenomena

Jun 10th, 2010 1h 9m

Prof. Itzhak BENENSON, Geography, University of Tel-Aviv, Israel. Geosimulation treats the city as a creature, the complexity of which is above the complexity of physical and chemical systems, but below the complexity of a human self. It thus a

Networks structures, main principles (eg scale-free, small-worlds)

Jun 10th, 2010 1h 8m

Prof. Marco TOMASSINI, ISI, University of Lausanne, Switzerland. Game theory offers a simplified but powerful metaphor of social behavior and decision processes under conflicting situations. We shall introduce some of these paradigms in the lan

Computational physics for the study of complex networks

Jun 10th, 2010 55m 2s

Prof. Roger GUIMERA & Prof. Marta SALES, Biochimics, Universitat Rovira i Virgili, Tarragona, Spain. Cells, the brain, ecosystems and economies are complex systems. In complex systems, individual components interact with each other, usually in

Multidimensional and multi-level network theory

Jun 10th, 2010 1h 9m

Prof. Noshir CONTRACTOR, Northwestern University, SONIC, USA. Recent advances in Web Science provide comprehensive digital traces of social actions, interactions, and transactions. These data provide an unprecedented exploratorium to model the
