Topical Iodine in Case of Radioactive Iodine Release

by  • 

It’s been difficult to get hold of potassium iodide tablets—people on the West Coast are getting worried about the possible farther radiation leaks from Japanese nuclear reactors and are trying to stock up. Fortunately, the topical iodine can work almost as well in an emergency. Betadine is a topical disinfectant and is usually easy to get. Here’s a reference to the study that shows the effectiveness for this purpose of Betadine absorbed through the skin of the abdomen: Toxnet.mln.nih.gov A 2 percent tincture of iodine on the abdomen over an area of approximately 200 mm by 100 mm works for adults as a preventive measure in a case of radioactive iodine presence in the atmosphere. When I was growing up, we were taught to draw a tic-tac-toe grid on our chests or a happy face on a tommy—it’s about the right amount and it is less scary for kids. Iodine will stain the skin and it will take a few weeks for the coloration to return to normal—be careful where you draw the happy face! A short note on use: Under no circumstances should Betadine be injested. It is poison. It is only for external use. Don’t use Betadine until…

Information Awareness & Failure Analysis

by  • 

Given the current state of affairs in Japan’s nuclear facilities, I thought it would be good to do a quick analysis of what’s going wrong and why the officials on the ground act as they do (based on very limited information that’s trickling in via the news sources). As of today (morning of March 14th), we have two reactors that have experienced explosions, partial core meltdowns, and multiple other failures. I’ve put together data from the news with failure analysis for an alternative view of the ongoing nuclear crisis in Japan. Like many aspects of usability, FAA (Federal Aviation Administration) was the first to develop practical understanding of Information Awareness and Failure Analysis—pilots and airplane designers what to minimize errors in flight and understand failure when it happens. Like the rest of the world, I’m extremely grateful for their insight into these two aspects of systems design and usability. Below is a quick introduction to the basics. Information Awareness Information Awareness is a wonderful term that describes the state of user’s knowledge of the problem at any particular time. This means that Information Awareness changes in time and from person to person. For designers of a complex system that aims…

Context and Information Processing

by  • 

Sometimes a book comes along that demonstrates in a very effective way the meaning of perfect. There’s a saying: “I will know when I see it.” But our seeing and knowing is wrapped up in our cultural bias and prone to mirroring errors. This contextual confusion over categorization is often cited during the discussion of American blindness to fat—when everyone in a group is over weight, no one is. The book “Athlete” shows what’s normal for various athletic groups. And what’s normal to some is amazing to others…

Information Scaffolding

by  • 

Here’s another way of thinking about crisis mapping as an ecosystem or a cell with a membrane allowing certain information to enter while keeping other out. Some data has data “receptors” in the organization and thus “gets in”. But some information doesn’t and some just doesn’t have the right format: wrong language, incomplete information, time delay, low quality, etc. Please let me know your thoughts on the communicative value of this illustration. Thank you! And here’s how Ushahidi can help.

Decision Scaffolding and Crisis Mapping

by  • 

I’m working on a series of illustrations to highlight the need for decision scaffolding during an aide mission. The ideas are based on the Ushahidi deployment experience in Haiti after the 2009 earthquake. But the idea is to make this more general. I would love ideas and recommendations on how to make this visualization better and more communicative. (read more about crisis mapping here) Crisis: Smoke Signals from Eye-Witnesses Let’s start with a crisis—a natural disaster or a political upheaval leaves thousands of people in desperate need of help. The people on the ground witness the suffering and use ICT (Information Communication Technology) to send up the spoke signals. Please not that Internet services might be compromised (due to deliberate actions taken by the authorities; infrastructure failures; chaotic conditions on the ground), but people tend to be very creative and use phone lines, radios, satellite links, and just person to person communication to get the information out there. During the current Libyan crisis, people were very creative: “To avoid detection by Libyan secret police, who monitor Facebook and Twitter, Mahmoudi, the leader of the Ekhtalef (“Difference”) Movement, used what’s considered the Match.com of the Middle East to send coded love…

Information Architecture: Building Mental Castles

by  • 

Prosopagnosia and Topographical Agnosia Not all memory structures are created equal. Humans have an amazing variability in our capacities to commit information to memory and to use this information flexibly to achieve our certain goals. Consider facial memory: our ability to remember a face even when out of context of original interaction. Like all cognitive abilities, facial recognition spans the continuum: there are people who basically lack this capacity (Oliver Sacks, a famous neurologist who wrote “A Man Who Mistook His Wife for a Hat” and “Awakenings” is one such example.) and then there are those who “never forget a face.” Most us are somewhere in between. I’m, personally, worse than most but perhaps not as bad as Dr. Sacks. (I taught science at a local elementary school, and to this day people stop me on a street and greet me in a very familiar way while I haven’t a slightest idea of who they are, never mind their names—very disconcerting.) The condition of being a lousy face recognizer is called Prosopagnosia and it tends to come with a complimentary Topographical Agnosia (or inability to identify places and thus having bad navigational skills). If you don’t remember faces and places,…
