We study a social network consisting of over 10(4) individuals, with a degree distribution exhibiting two power scaling regimes separated by a critical degree k(crit), and a power law relation between degree and local clustering. We introduce a growing random model based on a local interaction mechanism that reproduces the observed scaling features and their exponents. We suggest that the doubl...

regulations of use of social networks, as one of the key components in these networks, serve an important role in controlling the flow of traffic. the study of the harmonization of these terms and regulations can be a significant step to avoid congestion and (users’) rejection in the network. harmonization of traffic control regulations (tcr) among social networks is one of the best solutions...

Complex networks can be used to describe the Internet, social network, or more broadly describe a binary relation of a set of objects. Structure information of complex network helps the identification of the entity corresponding to nodes in the network. There is much research in this area, and the authors introduce these studies and their results in this chapter. The authors mainly present two ...

In this paper, we argue that coordination gaps, such as communication issues and task dependencies have significant impact on performance of work group. To address these issues, contemporary science suggests optimising links between social aspects of society and technical aspects of machines. A framework is proposed to describe social network structure and coordination performance variables wit...

Social networks play an important role in the Semantic Web. Several methods exist to extract social networks among people such as FOAF aggregation, email analysis, and Web mining. In this paper, we expand the existing techniques for social network mining from the Web and apply them to obtain a social network for different entities. Especially, two types of networks are investigated in this stud...

objectives: the present study was designed to investigate the effects of job satisfaction and mental health on job stress and the balancing effects of hardiness and availability of social support network in a group of medical staff. method: two hundred of surgery room staff were studied by utilizing a low-high social support network index, operating room stress factor index questionnaire, life ...

We study the following three questions: (1) How do the node degrees in a network affect security investments when nodes are strategic and have different security investment choices? (2) How can we provide an incentive to selfish nodes to increase their security investments in order to improve the overall security and reduce the social cost? (3) How much inefficiency does the selfish nature of n...
