Virtual Water Trade and Country Vulnerability: A network perspective

Sartori, Martina; Schiavo, Stefano - Istituto di Economia e Politica dell'Energia e … - 2014

We analyze the link between virtual water trade, that is, the flow of water embodied in the international trade of agricultural goods, and vulnerability to external shocks from the vantage point of network analysis. While a large body of work has shown that virtual water trade can enhance water...

Cluster analysis of weighted bipartite networks: a new copula-based approach

Chessa, Alessandro; Crimaldi, Irene; Riccaboni, Massimo; … - Economics, Markets, Institutions, IMT Lucca Institute … - 2014

In this work we are interested in identifying clusters of "positional equivalent" actors, i.e. actors who play a similar role in a system. In particular, we analyze weighted bipartite networks that describes the relationships between actors on one side and features or traits on the other,...

Synchronization analysis of complex networks with multi-weights and its application in public traffic network

An, Xin-lei; Zhang, Li; Li, Yin-zhen; Zhang, Jian-gang - In: Physica A: Statistical Mechanics and its Applications 412 (2014) C, pp. 149-156

On the basis of traditional weighted network, we study a new complex network model with multi-weights, which has one or … several different types of weights between any two nodes. According to the method of network split, we split the complex … network with multi-weights into several different complex networks with single weight, and study its global synchronization …

Indonesian Innovations on Information Technology 2013: Between Syntactic and Semantic Textual Network

Situngkir, Hokky - Volkswirtschaftliche Fakultät, … - 2013

Network and graph model is a good alternative to analyze huge collective textual data for the ability to reduce the dimensionality of the data. Texts can be seen as syntactic and semantic network among words and phrases seen as concepts. The model is implemented to observe the proposals of...

Optimum congestion pricing in a complex network

Babri, Sahar; McArthur, David Philip; Thorsen, Inge; … - Institutt for foretaksøkonomi, Norges Handelshøyskole … - 2013

Road tolls are a well established way of dealing with problems of congestion. Over recent years, the literature has expanded to take account of how congestion charges might interact with imperfections in other markets. In this paper, we consider the case where congestion occurs within a complex...

Network Formation and Geography : Modelling Approaches, Underlying Conceptions, Recent and Promising Extensions

Autant-Bernard, Corinne; Hazir, Cilem Selin - HAL - 2013

Due to the strong polarisation of economic activities in space and rise in collaborative behaviour, increasing attention has recently been devoted to the relationship between geography and network formation. The studies conducted on this topic reveal a high variation in terms of methodologies....

Cooperation Could Evolve in Complex Networks when Activated Conditionally on Network Characteristics

Chiang, Yen-Sheng - In: Journal of Artificial Societies and Social Simulation 16 (2013) 2, pp. 6-6

The investigation of how cooperation is achieved on graphs in the field of spatial game or network reciprocity has received proliferating attention in the biological and sociological literature. In line of the research, this paper provides an new account of how cooperation could evolve in...
