Applications of small-world networks to some socio-economic systems
Small-world networks (SWN) are found to be closer to the real social systems than both regular and random lattices. Then, a model for the evolution of economic systems is generalized to SWN. The Sznajd model for the two-state opinion formation problem is applied to SWN. Then a simple de,nition of leaders is included. These models explain some socio-economic aspects. c © 2003 Elsevier Science B....

متن کاملEconomic small-world behavior in weighted networks
The small-world phenomenon has been already the subject of a huge variety of papers, showing its appeareance in a variety of systems. However, some big holes still remain to be filled, as the commonly adopted mathematical formulation is valid only for topological networks. In this paper we propose a generalization of the theory of small worlds based on two leading concepts, efficiency and cost,...
متن کاملNoise induced transitions in some socio-economic systems
The paper proposes the use of some stochastic methods in order to explain the presence of the critical points in macroeconomic time series, starting from the classical linear model input-output elaborated by W. Leontief. The development of the model (N. GeorgescuRoegen, 1971) yields the set of the linear differential equations describing the dynamics of a system containing two or more interdepe...
متن کاملSmall-world Structure in Children’s Featured Semantic Networks
Background: Knowing the development pattern of children’s language is applicable in developmental psychology. Network models of language are helpful for the identification of these patterns. Objectives: We examined the small-world properties of featured semantic networks of developing children. Materials & Methods: In this longitudinal study, the featured semantic networks of children aged 1...
