Update: Since writing this post, I’ve repeatedly tried to delete the offending review from my profile, but Google Scholar keeps re-inserting it as part of its automated trawl through its corpus of articles. So it seems that the robots are determined to grant me these citations whether I want them or not.
Google Scholar is one of the most visible and widely-used examples of the rise of “impact measurement” in academia.
I was playing with some county-level data from the U.S. general election, partly out of a spirit of honest inquiry and partly out of a feeling of morbid curiosity. Because I had some county-level census data to hand, I took a look at the results using some extremely basic demographic information—the two variables that structure America’s ur-choropleths, namely population density and percent black. I focused on the counties that flipped from their vote in the 2012 general election.
Yesterday I had a conversation on Twitter with Josh Zumbrun that followed on from this tweet:
This is one of the most horrifying graphics I've ever seen:https://t.co/wM0VJZn0Wg pic.twitter.com/qaUaNFtRPl
— Josh Zumbrun (@JoshZumbrun) September 28, 2016 The striking maps he linked to tracked the rise in deaths due to drug-related overdoses over the past 15 years, caused in large part to the surge in use of heroin and synthetic opiates. The details are in the WSJ report on the problem.
Last year I wrote about vaccination exemptions in California kindergartens, drawing on school-level data provided by the state of California about the number of kindergarteners with “personal belief exemptions” (or PBEs) that allow them not to be vaccinated. Today I came across a ggplot package called ggbeeswarm that’s designed to create a “beeswarm plot”, or a 1-D scatterplot with a bit of information about the density of the distribution. I had used geom_jitter to do something like this for one of my plots last year, but the geoms in ggbeeswarm are better.
Here are two small sites I made recently, and which I may continue to tweak and expand. The first, plain-text.co, presents “The Plain Person’s Guide to Plain-Text Social Science”. It is designed to address some questions about managing research and writing projects in the social sciences using plain-text and free or mostly-free tools like Emacs (or other text editors), R, pandoc, and make. The second, vissoc.co which I’ve mentioned before, compiles notes from a short course in data visualization I taught last semester.
In the next week or two I’ll be talking to some social science students about tools for doing research and writing up results. Over the years I’ve accumulated various things on the topic, ranging from bits of advice to templates or things I use myself. My focus is on managing the various pieces of the work process in plain-text, especially when it comes to writing code you can read later, and keeping track of the work you’ve done.
ASA Section Membership and Revenues. I taught a half-sized introductory seminar on data visualization last semester. It’s an introduction to some principles of data visualization for working social scientists, and is focused mostly on teaching people how to use ggplot effectively. I’ve made the (slightly rough-and-ready) course notes available as a website. The notes include numerous code samples, .Rmd files for every week, and there’s a GitHub repository containing all the material to build the site, including the datasets used to make the plots.
Continuing my nonremunerative career as an IT Analyst, I updated my Apple Sales plots to the most recent (end of 2015) round of quarterly data. These plots were originally inspired by Dr Drang, and the trend for the iPad (shown below) continues to confirm his views. I also took the opportunity to clean up the code a little, and to fix a small problem in the earlier versions. The x-axis of the “Remainder” panel didn’t line up properly with the line plots above and below it.
A few days ago, Matt Yglesias shared this tweet from Liz Ann Sonders, Chief Investment Strategist with Charles Schwab, Inc:

— Liz Ann Sonders (@LizAnnSonders) January 15, 2016 Matt remarked that “Friends don’t let friends use two y-axes”. It’s a good rule. The topic came up a couple of times during the data visualization short course I taught last semester.
While making the maps for yesterday’s post about the extent of US federal landownership, I noticed an odd checker-pattern in one part of it. It flowed through northern Nevada and Utah, and then out a ways into southern Wyoming. I did enough work to make sure it wasn’t a coding error on my part, but didn’t pursue it any further. This morning, JP Lien asked me about it on Twitter, and we both took a closer look.
