Emergence of New Objects and Dynamic Networks Analysis
Explore the emergence of new objects, composition, temporal bounding, and catenating multiple views from various points. Dive into open problems in dynamic networks, complete network analysis, and the temporal bounding problem, using moving windows to freeze dynamic processes and understanding sequences of different lengths. Discover the fecundity and opportunities for something new through historical events and killing events over the years.

Presentation Transcript
Emergence of new objects Peter Bearman Columbia University Emergence, composition, the right object, temporal bounding,, catenating multiple views, history as a a series of moments experienced from multiple points of view simultaneously
There are a number of open problems w. dynamic networks. 1) Observation window lengths Source: Bender-deMoll & McFarland The Art and Science of Dynamic Network Visualization JoSS Forthcoming
Complete Network Analysis Network Connections: Role Positions Padgett, J. F. and Ansell, C. Just . Robust action and the rise of the Medici, 1400-1434. American Journal of Sociology. 1993; 981259-1319. This is the block reduction of the full 92 family network.
The Temporal Bounding Problem Years are arbitrary delimiters
Using Moving Windows to Freeze Dynamic Process A moving window where the network structure evolves as the window moves across the series of killing events
