The lectures for this week are on Monday, September 25th at 1:15pm and Tuesday, September 26th at 1:15pm. Both will be taped. They will be available here in QuickTime format approximately 24 hours after they occur.
Get the Videos Delivered (or if you have trouble w/ playback)
- Democracy Player is a free and open source video player/aggregator that will download and play back your class videos (sort of like a TiVo for your computer).
- Mplayer is another free and open source video player with its own codecs for playing Real(tm) and Quicktime(tm) (as well as all the other common formats). Some people who have problems with Democracy Player can play the videos with mplayer.
- VLC is another video player. It is, in my opinion (this being Dean), far easier to use than Mplayer.
Lecture Notes: Monday, Oct. 2. Networks and Network Dynamics
Social networks and online communities are a powerful and growing phenomenon. From the Internet to networks of friendship, disease transmission, and even terrorism, the concept--and the reality--of networks has come to pervade modern society. But what exactly is a network?

I. Three Types of Spatial Relationships:
(1) Physical Space: Actual physical distance
(2) Social Space: The gap between individualsâ wealth, education, ethnicity, or religion
(3) Network Space: Relationships between people (e.g., friend, friend-of-a-friend)
- Stanley Milgramâs Experiment: âMilgram gave letters to about 300 people in Boston and Omaha with instructions that the envelopes ultimately reach a single "target," a Boston stockbroker. The letters could be sent only to a personal friend of the current holderâ¦â
- This experiment is the origin of the idea that we are all connected by âsix degrees of separationâ â also known as âthe small-world phenomenonâ
II. The Importance of Network Space
A. âWe need to start thinking of individuals as nodes embedded in a complex web of social, economic, and institutional ties.â
B. âIn network space, two nodes can be closely connected regardless of their physical or social proximity.â
C. Network proximity can be significant in various positive and negativee real-world contexts
- Getting a job through a friend of a friend
- Disease transmission
- Cultural Fads
- Market trends
- Using the tools we learned about today, analyze the distribution network you have chosen for your project. What characteristics does it have? If you characterize it as a network, what are the nodes? What are the connections? Are some nodes in the network more important to influence than others?
Interesting Further Reading:
- Networks, Netwars, and the Fight for the Future - This (somewhat lengthy) paper discusses the concept of 'Netwar', "an emerging mode of conflict in which the protagonists - ranging from terrorist and criminal organizations on the dark side, to militant social activists on the bright side - use network forms of organization, doctrine, strategy, and technology attuned to the information age."
- Illicit, by Moises Naim. I recommend this book written by Foreign Policy magazine editor, on how smugglers, copycats and drug dealers are taking over the globalized economy, to understand the Â´dark sideÂ´of networks.
- Steven Johnson on "Emergence": "...leader is probably the wrong word for people who start trends, early adopters. It's not leader in the sense of a top-down broadcast role, where they have a big megaphone and they sit there and they say, "Okay, hooded sweatshirts, now! Everybody put them on!" They just are somewhere at a key point in the overall system of fashion, wherever that is, where they're connected to the right people, and what that core group decides ripples out very quickly through the whole system. So they're leaders in the sense that their ideas emanate from them, but they emanate in a much more distributed-network kind of way."
Tuesday, Oct. 3. Generating Buzz as Argument Strategy
What enables and nurtures online communities in an integrated media context? What sorts of phenomena have succeeded by the populist metric of the âNet. With all sites at least theoretically equally accessible, what gets people to go to particular thing? The popularity of these artifacts is an example of aggregation of minimal but powerful willing energy that is expressed just by adding hits and telling friends. What can these artifacts tell us about the elements of successful buzz creation? It is clear that we can aggregate energy to filter content: these artifacts demonstrate it. It is clear that we can aggregate energy to create structured repositories of useful information and resources: Wikipedia, free sound, the breaks, the latin library, and many other projects demonstrate it. Can we take it further by aggregating energy to make an argument for a principle? Downhill Battleâs 3 Notes and Runninâ shows us it is possible.

Interesting further reading:
- LonelyGirl15: Prank, Art, or Both - Article about LonelyGirl15, the incredibly popular online video diary focusing on the life of a home-schooled 16-year-old, who turned out to be a hired actress working for a team of filmmakers.
- Social networks are not immune to Astroturfing. Indeed due to the increased credibility lent a planted story by the accreditation function of social network, astroturfing can be spectacularly successful. It is interesting that these same attributes of social networks that make them vunerable to targeted disinformation, are also the same attributes that provide them with long-term resilence in the face of these attacks. This resilence is derived from two attributes of Social Networks.
- First their remarkable ability to identify suspect claims, and confirm/refute them. The "LonelyGirl15" prank is the latest high-profile example of this. Linus Torvalds described this phenomena as "given enough eyeballs, all bugs are shallow".
- Second the same 'network effects' that permit rapid dissemination of a successful misinformation attack, also permit rapid dissemination of rebuttal and debunkings. Moreover the high redundancy inherent in network topography renders it impossible for interested parties to supress the story. John Gilmore summarised this in his famous quote "The Net treats censorship as damage and routes around it."
- Meme, Counter-meme - Wired Magazine article discussing the concept of memes and memetic engineering as related to internet discussion boards.
- Buzzing the Web on a Meme Machine - New York Times article examining the interactions of the meme and the modern internet.
- A meme is a unit of cultural information capable of self-propagation and mutation in a manner somewhat analogous to the gene. In a nutshell, it's an idea or concept with a tendency to "catch on" and spread.
- To concretize the concept, think of the ubiquitous yellow-and-black "smiley face" image, the "All your base are belong to us" web phenomenon of the early 2000s, and the rapid proliferation--primarily online--of discussion and "buzz" concerning the movie "Snakes on a Plane" during the summer of 2006. All of these can be conceptualized as memes which have succeeded in widely propagating themselves (though they differ in the degree and longevity of their periods of prominence). They also demonstrate the meme's propensity for mutation, producing countless variations on the initial theme.
- The vast, networked information environment created by the internet has greatly facilitated the transmission of memes.
- Practitioners of viral marketing sometimes employ memetic techniques to encode self-perpetuating elements into their campaigns.
