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. Network optimization[edit] Network analysis[edit] Social network analysis[edit] Since the 1970s, the empirical study of networks has played a central role in social science, and many of the mathematical and statistical tools used for studying networks have been first developed in sociology.[2] Amongst many other applications, social network analysis has been used to understand the diffusion of innovations, news and rumors.

Network theory

Similarly, it has been used to examine the spread of both diseases and health-related behaviors. It has also been applied to the study of markets, where it has been used to examine the role of trust in exchange relationships and of social mechanisms in setting prices. Biological network analysis[edit] With the recent explosion of publicly available high throughput biological data, the analysis of molecular networks has gained significant interest. Link analysis[edit] Link analysis is a subset of network analysis, exploring associations between objects. See also[edit] 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]. To understand networks and their participants, we evaluate the location of actors in the network. Measuring the network location is finding the centrality of a node. We look at a social network -- the "Kite Network" above -- developed by David Krackhardt, a leading researcher in social networks. Degree Centrality Social network researchers measure network activity for a node by using the concept of degrees -- the number of direct connections a node has.
