A great deal of work in recent years has been devoted to the topic of \complexity,' its measurement, and its implications. Here, the notion of algorithmic complexity is applied to the analysis of social networks. Structural features of theoretical importance such as structural equivalence classes are shown to be strongly related to the algorithmic complexity of graphs, and these results are exp...

Empirical support for the assumption that cliques are major determinants of reputational influence derives largely from the frequent finding that organizations which claimed that their cliques’ connections are influential had an increased likelihood of becoming influential themselves. It is suggested that the strong and consistent connection in cliques is at least partially responsible for the ...

The paper investigates the effects of collaboration networks on inventive productivity within an industrial research environment. A distinction is made between two kinds of network structures: structural holes offering information brokerage opportunities to individuals and network closures supporting co-specialization of individuals. Hypotheses regarding the effects of network positions on the ...

This paper attempts to examine the effects of virtual team dimensions on social identities of its members. A review of the literature shows that the geographically dispersed, culturally diverse as well as temporary dimensions of virtual teams do not match with their stability as members have different ethnic, social, or cultural backgrounds. Sources like culture, place, and time seem to continu...

It has become well known that the knowledge about key network members is essential for doing business successfully through online social networking sites. As of now, most studies targeted at identifying key members have used network structural centrality measures. Little emphasis has been placed on member activities to identify key members in a network; even though gathering and utilizing such ...

The paper outlines a bioinspired approach named "network nervous system" and methods of simulation of infrastructure attacks and protection mechanisms based on this approach. The protection mechanisms based on this approach consist of distributed procedures of information collection and processing, which coordinate the activities of the main devices of a computer network, identify attacks, and ...

This paper concerns the assessment of linear cause-effect relationships from a combination of observational data and qualitative causal structures. The paper shows how techniques developed for identifying causal effects in causal Bayesian networks can be used to identify linear causal effects, and thus provides a new approach for assessing linear causal effects in structural equation models. Us...

The purpose of this paper is to examine the effect of social networking sites’ (SNSs) characteristics on Egyptians’ perception and attitude towards the 25/30 uprisings, also known as the “Arab Spring”. Data were obtained from 422 Egyptian university students using SNS by means of questionnaire. Structural Equation Modeling (SEM) was conducted to test the research hypotheses. The study results i...

This research explores how inter-organizational relationship interacts with factors affecting the development and implementation of information sharing. On the basis of the resource-based view and relational risk perspective, we developed a model which comprises three research hypotheses with three constructs, including relational benefits, relational risk, and information sharing. The construc...
