Is obesity contagious?

May 19, 2010

I recently watched a TED talk on the spread of obesity, and have since read the paper. The results are amazing, here is a summary:

“A person’s chances of becoming obese increased by 57% (95% confidence interval [CI], 6 to 123) if he or she had a friend who became obese in a given interval. Among pairs of adult siblings, if one sibling became obese, the chance that the other would become obese increased by 40% (95% CI, 21 to 60). If one spouse became obese, the likelihood that the other spouse would become obese increased by 37% (95% CI, 7 to 73). These effects were not seen among neighbors in the immediate geographic location. Persons of the same sex had relatively greater influence on each other than those of the opposite sex. The spread of smoking cessation did not account for the spread of obesity in the network.”

I love the question posed, are you making your friends fat or are they making you fat?

There are some excellent visualisations in the this talk.

Open Knowledge Conference and Where Does My Money Go

April 25, 2010

I attended the Open Knowledge Conference yesterday in London. It was a excellent day of talks about Open Data and the work different people and organisations are doing.

Some of my favourites talks included:

  • The Post-Analogue World, Glyn Moody, opendotdot – This was a fast paced talk which only made the topic even more interesting and exciting. I do hope Glyn writes about this, as there were some excellent examples of how the music industry could change its business models!
  • Making the Physical from the Digital, Ben O’Steen – An excellent talk on converting digital data to physical data, printing a book on one continuous till receipt was quite thought provoking. The MP’s expenses receipts, service not included, was a good idea – this area still leaves a nasty taste though.
  • The Straight Choice, Richard Pope – An amazing idea, store all of those election flyers. Richard’s synopsis of the bad, and some good leaflet was eye opening. Interested to see what sub-projects are spawned from this site.
  • Where does my money go, not sure on the presenters. This was an interesting presentation. Only the day before I was sent the link to the prototype visualisation and upon seeing it I was amazed at how they have represented such a huge amount of data in a clear and concise manner, and also that they had managed to “crunch/clean/process” this data to enable the visualisation. The talk made it very apparent the amount of work, effort and I am sure frustration that was put into getting, processing and undersanding the data…. And it is only 27,000 rows of data from a database of 27 million (if I remember correctly). Absolutely brilliant job.

All the of the talks I attended were brilliant, in fact I wanted to go to others but they overlapped.

Really enjoyed the day, big thank you to the organisers and presenters.
