Idea Framing, Metaphors, and Your Brain. Networks4newbies. NetLab is an interdisciplinary scholarly network studying the intersection of social networks, communication networks, and computer networks.


Centered at the University of Toronto, NetLab members have come from across Canada and the United States as well as from Chile, Germany, Hungary, Israel, Japan, Norway, Portugal, and the United Kingdom. NetLab has developed since 2000 from an informal network of collaborators into a far-flung virtual laboratory. Its research focuses on the interplay between social and technological links, including the understanding of social capital in job searches and business settings, new media and community, Internet and personal relations, social media, households, networked organizations, and knowledge transfer in research networks.

Learning Networks: Theory and Practice

Talk at the opening of the International Conference on Methods and Technologies for Learning at the Palazzo dei Normanni, Palermo, Sicily. Unfortunately rushed, my talk wasn't everything I had hoped, though people were kind enough to say nice things afterward (including one who, after seeing the slides, said it's a talk I should give in full one day). Still, here are the slides and the MP3 of Learning Networks (3.3 megabytes). [Slides] [Audio] [Conference Link] Network theory. A small example network with eight vertices and ten edges.

Network theory

It has applications in many disciplines including statistical physics, particle physics, computer science, electrical engineering, biology, economics, operations research, and sociology. Applications of network theory include logistical networks, the World Wide Web, Internet, gene regulatory networks, metabolic networks, social networks, epistemological networks, etc; see List of network theory topics for more examples. Euler's solution of the Seven Bridges of Königsberg problem is considered to be the first true proof in the theory of networks.[1]

Social Network Analysis. Social network analysis [SNA] is the mapping and measuring of relationships and flows between people, groups, organizations, computers, URLs, and other connected information/knowledge entities.

Social Network Analysis

The nodes in the network are the people and groups while the links show relationships or flows between the nodes. SNA provides both a visual and a mathematical analysis of human relationships. Management consultants use this methodology with their business clients and call it Organizational Network Analysis [ONA]. ONA allows you to x-ray your organization and reveal the managerial nervous system that connects everything. To understand networks and their participants, we evaluate the location and grouping of actors in the network. We look at a social network -- the "Kite Network" above -- developed by David Krackhardt, a leading researcher in social networks.
