This study aims to analyze the characteristics of global virtual water trade (GVWT), such as the connectivity of each trader, vulnerable importers, and influential countries, using degree and eigenvector centrality during the period 2006–2010. The degree centrality was used to measure the connectivity, and eigenvector centrality was used to measure the influence on the entire GVWT network. Mexi...

Network analysis has emerged as a key technique in communication studies, economics, geography, history and sociology, among others. A fundamental issue is how to identify key nodes in a network, for which purpose a number of centrality measures have been developed. This paper proposes a new parametric family of centrality measures called generalized degree. It is based on the idea that a relat...

Visual attention is an indispensable component of complex vision tasks. In this paper, a multiscale, complex network-based approach for determining visual saliency is described. It uses degree centrality (conceptually and computationally the simplest among all the centrality measures) over a network of image regions to form a saliency map. The regions used in the network are multiscale in natur...

We consider growing random networks {Gn}n≥1 where, at each time, a new vertex attaches itself to collection of existing vertices via fixed number m≥1 edges, with probability proportional function f (called attachment function) their degree. It was shown in [BB21] that such network models exhibit two distinct regimes: (i) the persistent regime, corresponding ∑i=1∞f(i)−2<∞, where top K maximal de...

one of the most important preparation steps of co-management projects implementation is recognizing key actors at local community level. these actors can assist managers and planners as local leaders and social powers. by applying social network analysis and centrality index at actors’ level of “goormomenin” common rangeland, kalateh region, daamghan city in this research, social powers and loc...

Background and Objective: The evaluation of the publishing trend of articles in various scientific fields provides an insight into the efforts of researchers in the field of knowledge. Accordingly, the present study has evaluated and analyzed the scientific publications on brucellosis conducted by Iranian researchers using scientometrics methods and analysis of social networks. Methods: The pr...

Building and using social networks is an important factor in individuals’ personal as well as professional success. In the present work, we examine how individuals’ regulatory focus relates to their networking behavior. Findings from a sample of 300 entrepreneurs across 25 networking groups showed that a general focus on motivations for growth and advancement (promotion) predicted an increase i...
