A couple of articles have passed across our desk in recent days that
illustrate the impact -- and importance of understanding -- decentralized (or "distributed") systems and complex adaptive systems<http://www.eas.asu.edu/%7Ekdooley/casopdef.html> . For starters, take a look at "Reinventing 911 How a swarm of networked ?citizens is building a better ?emergency broadcast system."* http://www.wired.com/wired/archive/13.12/warning.html * Author Gary Wolf writes: "I've been talking with security experts about one of the thorniest problems they face: How can we protect our complex society from massive but unpredictable catastrophes? The homeland security establishment has spent an immeasurable fortune vainly seeking an answer, distributing useless, highly specialized equipment, and toggling its multicolored Homeland Security Advisory System back and forth between yellow, for elevated, and orange, for high. Now I've come [to Portland, Oregon] to take a look at a different set of tools, constructed outside the control of the federal government and based on the notion that the easier it is for me to find out about a loose dog tying up traffic, the safer I am from a terrorist attack. "To understand the true nature of warnings, it helps to see them not as single events, like an air-raid siren, but rather as swarms of messages racing through overlapping social networks, like the buzz of gossip. Residents of New Orleans didn't just need to know a hurricane was coming. They also needed to be informed that floodwaters were threatening to breach the levees, that not all neighborhoods would be inundated, that certain roads would become impassible while alternative evacuation routes would remain open, that buses were available for transport, and that the Superdome was full. "No central authority possessed this information. Knowledge was fragmentary, parceled out among tens of thousands of people on the ground. There was no way to gather all these observations and deliver them to where they were needed. During Hurricane Katrina, public officials from top to bottom found themselves locked within conventional channels, unable to receive, analyze, or redistribute news from outside. In the most egregious example, Homeland Security secretary Michael Chertoff said in a radio interview that he had not heard that people at the New Orleans convention center were without food or water. At that point they'd been stranded two days. "By contrast, in the system Botterell created for California, warnings are sucked up from an array of sources and sent automatically to users throughout the state. Messages are squeezed into a standard format called the Common Alerting Protocol, designed by Botterell in discussion with scores of other disaster experts. CAP gives precise definitions to concepts like *proximity, urgency,* and *certainty*. Using CAP, anyone who might respond to an emergency can choose to get warnings for their own neighborhood, for instance, or only the most urgent messages. Alerts can be received by machines, filtered, and passed along. The model is simple and elegant, and because warnings can be tagged with geographical coordinates, users can customize their cell phones, pagers, BlackBerries, or other devices to get only those relevant to their precise locale." Second item of interest I'm sure many of you noted Dexter Filkins Pg1 lead story in the NYT on Friday, 2 Dec. 2005. The online version headline is "Profusion of Rebel Groups Helps Them Survive in Iraq<http://analyticjournalism.blogharbor.com/SavedWebArticles/FilkinsProfusionOfRebelGroups.html> ." That, unfortunately, lacks the truth and insight of the print version headline: "Loose Structure of Rebels Helps them Survive in Iraq -- While Al Qaeda Gains Attention, Many Small Groups Attack on Their Own." It seems that finally someone in the journalism community has figured out that what's happening in Iraq -- and around the world -- is a decentralize, CAS. Too bad journalists -- journalism educators, students and professionals -- haven't been exposed to the concepts and vocabulary to really present the problem in all its, ahem, complexity. ------------------------------ --tj ============================================== J.
