Working Memory (with R Code!)
by Ryan in Epidemiology as a liberal art
Just got Daniel Kahneman's Thinking, Fast and Slow for my birthday, and if the first two chapters are any indication, this is an amazing book.To prove it, I just wasted 3 hours programming up Kahneman's Add-1 exercise in R. In his words:To start, make up several strings of 4 digits, all different, and write each string on an index card. Place a blank card on top of the deck. The task you will perform is called Add-1. Here is how it goes: Start beating a steady rhythm. Remove the blank ........ Read more »

Some data on college degrees
by Ryan in Epidemiology as a liberal art

It described the high attrition rate of college students in STEM fields, and made the basic argument that science and engineering curricula are too hard, too dry, and far too divorced from reality. The answer? Projects. Group projects. Hardly earth-shattering if you've been through an engineering program recently, but the article raised some interesting points about heavily abstract coursework ........ Read more »

Coffee and ALS
by Ryan in Epidemiology as a liberal art
Out of Italy this week comes a study on coffee as a possible preventative for ALS. We've known for some time of a strong and apparently robust inverse relationship between coffee and Parkinson's Disease and Alzheimer's Disease, two neurodegenerative diseases with broad similarities to ALS. But rather surprisingly, no studies have directly tested the hypothesis that coffee consumption lowers the risk of ALS. And as the authors of the current study note up front, that wasn't their goal h........ Read more »
