abstract: the objective of this paper is to measure and explain the relationship between facebook users’ social capital and their political participation in real world. following political changes in the world and in the middle east, there are growing interest among researchers to work on political participation and facebook usage. we therefore developed this interest into this research paper i...

Lately, network sampling proved as a promising tool for simplifying large real-world networks and thus providing for their faster and more efficient analysis. Still, understanding the changes of network structure and properties under different sampling methods remains incomplete. In this paper, we analyze the presence of characteristic group of nodes (i.e., communities, modules and mixtures of ...

In software engineering activity, requirement elicitation is the first phase, in which important requirements related to the project are gathered from different stakeholders. Most projects fail due to inadequate stakeholders and requirements. To identify and prioritize stakeholders and their requirements a method called StakeRare is developed by using social networks and collaborative filtering...

Routing in highly mobile, energy constrained wireless networks remains an open research area. The majority of energy aware protocols are designed for stationary networks, and conversely, mobile ad hoc protocols rarely incorporate information about node energy. Obtaining global information about energy distribution across the network is wasteful of scarce resources, so we introduce a ranking sys...

a r t i c l e i n f o Keywords: Service triad Social capital Interconnectedness Actor bonds Case study Inter-firm networks are becoming increasingly important, as firms are influenced by their direct relationships and the networks surrounding them. Our study contributes to the understanding of interconnectedness among business relationships, as we analyze how different dyadic relationships in a...

A significant volume of social science research effort is being directed at examining food systems that are regarded as being in some way ‘alternative’ to ‘conventional’ ways of food provisioning. This article provides an up-to-date critical review of this work on alternative food networks (AFNs), with particular emphasis on debates about definition, the types of AFN studied and the main concep...

The concept of Information Propagation has been studied to illustrate the particular, discrete, and explicit behavior of the nodes in a complex and highly distributed and connected networks. The complex network structure exhibits various challenges towards information propagation due to the usage of diversified communication protocol and dynamic behavior in the context of uncertainty. This pape...

Due to the large diffusion of social networks, these media offer a huge platform where users share judgements, comments and opinions that organization could exploit for achieving information on consumers’ preferences and market trends, with benefits for the development of more effective marketing strategies. In particular, this paper focuses on the use of Facebook among youth, with emphasis on ...
