Networks and Epidemics
To figure out how a disease is spreading, look for hubs.

An international dream team of flu experts assembled in Chinatoday.
Underscoring the urgency that public health agencies feel about theemergence of a new kind of bird flu, the team is headed by Dr. KeijiFukuda, the World Health Organization's top influenza scientist.
Before he left Geneva, Fukuda explained the wide-open nature of

The Powerof Weak Ties
Weak ties have high value as multipliers of our attention capacity, and as a source of tips for good shopping deals, job possibilities, and dating partners. —Dr. Daniel Goleman
NetworkTopology
Chapter 1In the !ick of It
Linear
Mutual ties (flow in both directions)
!e Bucket Brigade
Photo from FEMA
Information is directional (inbound and outbound ties)
!e Telephone Tree
Creates cascade effect
Reduces number of steps
Squad is more intra-connected than inter-connected with other squads
!e Military SquadTightly interconnected groups
Two-way tie between all members of squad
SocialNetworks
TermsA Social Network: consists of all the connections and ties within a group or collection of groups
A group is a collection of individuals defined by a common attribute (it need not contain information about connections)

Sociogramswho is connected to whom
Activism Goes OnlineYou might think increased discussion would bring us politically closer but this map of political blogs in America shows otherwise.
Online social networks appear to be strongly homophilous and polarized.
The structure of a network determines its behavior.

‘stay with your self’ (through the widening circles of belonging)
Emergence: a fundamental property of Complex Systems
• System: ‘to hold together’• Whole >> sum of parts (network interactions)• Cells, individuals, ideas, social groups, Homo
sapiens, ecosystems, Earth (Gaia)
Labeling: as fundamental to humans as Tribalism
• Cliques, tribes, teams, religions, cultures…• Emergent identity at the group level
(self-other discrimination)

SMALL WORLD NETWORKS:• Every node is connected to every other node, but mostly indirectly• Few nodes are highly connected• Low average path length• High clustering (substructure)• Seem to be ubiquitous in nature, a Unifying principle Social systems, brains, power grids!
Terrorist networks, metabolic networks, food webs (ecosystem networks)!
Science publication co-authorship, board memberships, rap musicians!
The Internet!
Why are SWNs ubiquitous?The Nature of disturbance/flow (Uncertainty): It’s similar across scales and systems, like SWNs!! Mass extinctions, earthquakes, fires, stock market crashes, Internet attacks, traffic flow patterns, etc. all exhibit ‘self-organized criticality’ evidenced by power laws. (Many more small than large disturbances or flows)
SWNs (across scales and systems) persist in the face of Uncertainty (across scales and systems): emergent identity, robust to disturbance
Cells (with Metabolic Networks),
Tissues and organs (Neural Networks),
and Individuals in Society (Social Networks)
all emerge and persist(identity) due to Collective SWNDynamics…

as do the Ecosystems of which we are part (with all of their creatures).
SWN ubiquity across scales and systems reveals a collective Nature,
a larger planetary whole, and aunifying context for our drive to belong,and for our empathy and courage.
