The Bak–Sneppen model of co-evolution is used to derive synthetic time series with a priori specified fractal dimension (or Hurst exponent) through a mixing of processes in various lattice dimensions. Both theoretical and numerical analyses concern the avalanches at the critical threshold and...

The salience of the international purchasing office (IPO) in the management of international sourcing activities of multinational corporations (MNCs) has steadily increased, in developed and emerging economies, since the first adoption of this supply chain strategy in the 1980s. The aim of this...

The article aims to give an overview of the main models in the spin-off research field and to streamline further research in this domain. The main evolution and performance models known in literature will be analysed. The evolution models will be discussed in increasing order of complexity....

As information technology has advanced, people are turning to electronic media more frequently for communication, and social relationships are increasingly found on online channels. However, there is very limited knowledge about the actual evolution of the online social networks. In this paper,...

The article aims to give an overview of the main models in the spin-off research field. The main evolution models known in literature will be analyzed. The evolution models will be discussed in increasing order of complexity. However, the existing models will prove to be inadequate to reflect...
