6. Aphorisms about Networks Social Networks:
Its not what you know, its who you know.
Cognitive Social Networks:
Its not who you know, its who they think you know.
Knowledge Networks:
Its not who you know, its what they think you know.
10. Social Drivers:Why do we create and sustain networks? Theories of self-interest
Theories of social and resource exchange
Theories of mutual interest and collective action Theories of contagion
Theories of balance
Theories of homophily
Theories of proximity
Theories of co-evolution
14. Enter Semantic Web/Web 2.0Its all about Relational Metadata
Technologies that capture communities relational meta-data (Pingback and trackback in interblog networks, blogrolls, data provenance)
Technologies to tag communities relational metadata (from Dublin Core taxonomies to folksonomies (wisdom of crowds) like
Tagging pictures (Flickr)
Social bookmarking (del.icio.us, LookupThis, BlinkList)
Social citations (CiteULike.org)
Social libraries (discogs.com, LibraryThing.com)
Social shopping (SwagRoll, Kaboodle, thethingsiwant.com)
Social networks (FOAF, XFN, MySpace, Facebook)
Technologies to manifest communities relational metadata (Tagclouds, Recommender systems, Rating/Reputation systems, ISIs HistCite, Network Visualization systems) Social bookmark managers such as Del.icio.ous (http://del.icio.us), unalog (http://unalog.com),
BlinkList (http://www.blinklist.com), Connectedy (http://www.connectedy.com) or GiveALink
(http://givealink.org) support the collection, categorization and sharing of web linkages. Flickr
(http://www.flickr.com) supports the collection, sharing, and tagging of photos. Common to all of them is
the importance of tags to create folksonomies. Folksonomy is a portmanteau word combining folk and
taxonomy. It refers to the organization of knowledge based on tags attached by thousands of users to
millions of records. It is a rather decentralized form of classification that uses the wisdom of crowds to
classify records. Folksonomies are typically displayed as list of most commonly used tags.
Tagclouds The text font type, color, and size are frequently used to indicate the number of records that have this tag, the novelty of a tag, activity bursts for the usage of a tag, etc.

19. Hurricane Katrina 2005 Formed: Aug 23, 2005
Dissipated: Aug 31, 2005
Highest wind: 175 mph
Lowest press: 902 mbar
Damages: $81.2 Billion
Fatalities: >1,836
Areas affected: Bahamas,
South Florida, Cuba, Louisiana (especially Greater New Orleans), Mississippi, Alabama, Florida Panhandle, most of eastern North America
Overview of Hurricane Katrina. Disasters require coordination, coordination between organizations is not always according to plan (Carters Port Authority Police radio paper). Therefore, the structure of the communication is important for the proper actions during a disaster Analyzing the structure during an actual disaster can detect problems and solutions can be developed in real time (This is yet to be done).
Trivia note: How may storms/hurricane have been named Katrina? 6 (1967, 1971, & 1975 in the Pacific; 1981, 1999, & 2005 in the Atlantic)Overview of Hurricane Katrina.

Situation (What, Where, and When)
Action in Progress
Action Planned
Probable Support Requirements and/or Support Available
Other items
SITREPs are Situation Reports that are written by lower or on site commands to report the situation to those higher up. They should all contain this basic information and in this basic format.SITREPs are Situation Reports that are written by lower or on site commands to report the situation to those higher up.

26. Time Slice 2: 8/26 to 8/27/2005 Slice 2: Nodes mentioned at least 4 times or more: This the increased mentions of other states and many Florida counties. FEMA is moving out from the center and American Red Cross is moving in. Petroleum nodes have faded. There seem to be a lot of travel related nodes (toll road, turnpike, expressway, etc. Evacuation?). New Orleans is moving towards the middle of the network from the fringe.

28. Time Slice 3: 8/28 to 8/29/2005 Slice 3: One large component of nodes of frequency 4 or higher (i.e., mentioned at least four times). It looks like more states are being mentioned (and cites/counties in those states). FEMA is getting larger and with about the same centrality. American Red Cross is at 7 oclock and becoming more central. Governor Bush is moving out of the center (as he did in the last slice, 1st slice he was in the center). New Orleans is at about the same distance from the center. There is an oil grouping on the right (1 oclock), but it is discussing the Strategic Petroleum Reserve. Florida Power and Light is prominent just left of center (getting power back to Florida customers); there are power related concepts throughout the network.

American Red Cross has move out of the center (just this slice they will move back later), this is consistent with the Network Centrality Graph. FEMA is also moving into the center this slice. There is a lot oil an energy concerns here. Shelters, MRE (meals ready to eat), and Power are key concepts Alabama Power has join with Florida Light and Power (FL&P). Search and Rescue is showing up (S&R). The National Guard has joined the network.

35. Change in Network Centrality Rankings This slide gives some trend information on two players in the disaster: FEMA and ARC. It is interesting that FEMA starts low and moves up, while the Red Cross starts high and ends low: are they trading roles or emphasis: FEMA manages the emergency, and Red Cross coordinates the recovery?

37. 3D Strategy for Enhancing Knowledge Networks Discovery: Effectively and efficiently foster network links from people to other people, knowledge, and artifacts (data sets/streams, analytic tools, visualization tools, documents, etc.)
If only NSF knows what NSF knows.
Diagnosis: Assess the health of internal and external networks - in terms of scanning, absorptive capacity, diffusion, robustness, and vulnerability to external environment
Design: Model or re-wire networks using social and organizational incentives (based on social network research) and network referral systems to enhance evolving and mature communities And heres how we propose to reach our objectives for Redes ---using 3D strategy

38. Discovery Problems in Knowledge Networks IDC found Fortune 500 companies lose $31.5 billion annually due to rework and the inability to find information.
The Delphi Consulting Group found that:
Only 12 percent of a typical company's knowledge is explicitly published. Remaining 88 percent is distributed knowledge, comprised of employees' personal knowledge.
Up to 42 percent of knowledge professionals need to do their jobs comes from other people's brains - in the form of advice, opinions, judgment, or answers. More often than not, much of this exchange does not follow channels displayed in an organizational chart. [Does this audience need sources?][Does this audience need sources?]

Three regions japan, western europe, and us
Top absorbers: Printing and decoration Tomishima san and Paul Baker Neither from the US. Paul is expert the other is not.
Paul connects all three regions
Paul Baker is printing and decoration technology chapter leader. Highest capacity for absorption.
He is the right one for the job. In fact if You would want to identify someone with his characteristics to play that role.
This is the only CoP only has a supplier sun chemical and it shows up in multiple regions (japan and China)

46. Designing CoPs as Small World Networks Industries with small world network structures are more innovative!
Networks where people spend most of their time communicating with one another in a group (cluster) and spend some time communicating with others outside (short cuts)
Small world networks exhibit high levels of clustering and few shortcuts
Clusters engender trust and control, maximize capability for exploitation
Shortcuts engender unique combinations of network resources, maximize capacity for exploration
49. Wiring the PackEdge CoP Network for Success Increase the likelihood to give and get information to the right target and source respectively
Benefits for CoP
Increase absorptive capacity from 45.3% to 53.4%
Reduce number of steps for diffusion from 4.3 to 2.6
Costs for CoP
Increase communication links of network leaders from 28 to 38 (~ 150 new links).
Increase criticality of network leaders from 26.7 % to 48.5%
