Here we intend to re-examine Axelrod’s ‘adaptive culture model,’ i.e., a simulation of the dissemination of culture through social interaction proceeding by local convergence and resulting an emergence of global polarization at some degree (Axelrod, 1997). Our purpose is twofold: (i) to increase the produced relatively low heterogeneity in Axelrod’s model and (ii) to explore how the social netw...
Social systems theory is dominated by a reductionistic individualism and a dualistic functionalism. Especially the latter doesn’t adequately integrate the human being. In order to avoid dualism, mechanistic determinism and reductionism, a dialectical concept of social systems that is based on the notion of self-organization seems necessary. In order to establish a dialectical theory of social s...
We present a stochastic model for a social network, where new actors may join the network, existing actors may become inactive and, at a later stage, reactivate themselves. Our model captures the evolution of the network, assuming that actors attain new relations or become active according to the preferential attachment rule. We derive the mean-field equations for this stochastic model and show...
This paper describes the application of temporal link and content analysis to the well-known Enron e-mail dataset. TeCFlow permits to extract dynamic movies of the evolution of social networks, identifying gatekeepers and other central actors, as well as to generate temporally correlated cluster maps of e-mail content. Our approach combining social network analysis with information mining permi...
How long can Facebook survive? Complex Physics Model for Predicting the Life Cycle of Social Network
A social network means a social structure made up of a group of actors (such as individuals or organizations) and the dyadic communication ties between these actors. The social network perspective provides a clear way of analyzing the structure of whole social entities. The study of these structures uses social network analysis to identify local and global patterns, locate influential entities,...
The effect of facial appearance, speech style, and handwriting on personality attributions was examined. The source consistency hypothesis predicted that an actor will receive consistent attributions across all three types of information. The differential information hypothesis predicted that different personality dimensions are used to differentiate the actors within each type of information. ...
We present a generative model for conversational dialogues, namely the actortopic model (ACTM), that extend the author-topic model (Rosen-Zvi, et.al, 2004) to identify actors of given conversation in literary narratives. Thus ACTM assigns each instance of quoted speech to an appropriate character. We model dialogues in a literary text, which take place between two or more actors conversing on d...
Academics and other researchers regularly engage in strategic interactions— bargaining, cooperation, collaboration, etc. Given this strategic setting, we ask: how do the dynamics of social learning in epistemic communities influence outcomes of various actors? We focus, in particular, on minority groups in academia. As we show, evolutionary game theoretic models indicate that such actors may be...
According to the small-world concept, the entire world is connected through short chains of acquaintances. In popular imagination this is captured in the phrase six degrees of separation, implying that any two individuals are, at most, six handshakes away. Social network analysis is the understanding of concepts and information on relationships among interacting units in an ecological system. I...
through uncovering the underlying elements of language, this research aims to reveal the hidden layers of meaning in press texts in the framework of a critical discourse analysis. having used socio-semantic features of van leeuwen's model (1996), this paper has studied, qualitatively, 40 issues of four iranian persian publications for a period of two months, from july 22 to september 21, 2011. ...
