Coding Responses

While listening to all of the sound files was extremely time consuming (and kind of mind-numbing), coding proved to almost as bad. Since this was essentially a pilot study (i.e. we weren’t working off of much background and were using this to plan for further research), I had nothing to base the coding off of other than our raw data. After talking with my advisor, we decided to use 4 main categories – 1 = perfect, 2 = minor errors, 3 = major errors/unintelligible, and 4  = metathesis. The plan was to hone these categories down as I started listening to data so the coding would effectively summarize our data.

Experiments to Experiments: Final Post

In long term experiments, sometimes it takes experiments to get to the start of new experiments. For my summer in lab, this was the case for much of the time. In my last blog post, I talked about the polymerizations of 11-aminoundecanoic acid. The sample of polymer with four regions pictured in that post has gone on to become a multi-month acid aging experiment. On the very last day of lab, one of my lab peers and I spent the afternoon preparing the acid solutions for this experiment. The samples of polymer will be aged in four different conditions — acetic acid, propionic acid, butyric acid and water, all in a 120C oven. To prepare the samples for aging in anaerobic conditions, argon was bubbled into the pressure tubes in which they aged for a minimum of 20 minutes.
