A corpus analysis of rock harmony
[PDF] - The analyses were encoded using a recursive notation, similar to a context-free grammar, allowing repeating sections to be encoded succinctly. The aggregate data was then subjected to a variety of statistical analyses. We examined the frequency of different chords
and chord transitions ... Other results concern the frequency of different root motions, patterns of
co-occurrence between chords, and changes in harmonic practice across time.

Although much has been said
about the demographic composition of the United States Congress, much less has been said about the thousands of staffers who work behind the scenes, drafting legislation, interacting with constituents, and advising their congressperson. The National Journal has created two infographics
that attempt to describe this silent, but influential workforce.

is a veteran American cartoonist best known for his delightful comic-book guides to science and history, many of which have previews online. Chief among them is his long-running Cartoon History of the Universe
(later The Cartoon History of the Modern World
), a sprawling multi-volume opus documenting everything from the Big Bang to the Bush administration. Published over the course of three decades, it takes a truly global view -- its time-traveling Professor thoroughly explores not only familiar topics like Rome and World War II but the oft-neglected stories of Asia and Africa, blending caricature and myth with careful scholarship (cited by fun illustrated bibliographies
) and tackling even the most obscure events with intelligence and wit
. This savvy satire carried over to Gonick's Zinn
chronicle The Cartoon History of the United States
, along with a bevy of Cartoon Guides
to other topics, including Genetics, Computer Science, Chemistry, Physics, Statistics, The Environment
, and (yes!) Sex
. Gonick has also maintained a few sideprojects, such as a webcomic look at Chinese invention
, assorted math comics
), the Muse magazine
mainstay Kokopelli & Co.
(featuring the shenanigans of his "New Muses"
), and more

Go figure: How to succeed in business by doing nothing
Article about variability in business and why it is sometimes better to do nothing.
"You're a dynamic business leader. Let's say you make widgets - though you might equally make big-budget Hollywood movies.
Your widgets, or your movies, vary. Some widgets are perfect, some a tad too long. Some movies make mega-bucks at the box office, some bomb.
So what do you do? Well, you're dynamic, so you react, of course. Something must be done. "

"Nearly half of pregnancies among American women are unintended, and four in 10 of these are terminated by abortion.... At least half of American women will experience an unintended pregnancy by age 45, and, at current rates, about one-third will have had an abortion." Abortion is one of the most common medical procedures in the U.S., but it can be very difficult to get unbiased information about the procedure. From Jezebel: The Girl's Guide to Having an Abortion

Following the Journal of Personality and Social Psychology
's decision to publish Daryl Bem's writeup of 8 studies
(PDF) purporting to show evidence for precognition (previously
), researchers from the University of Amsterdam have written a rebuttal
(PDF) which finds methodological flaws not only in Bem's research, but in many other published papers in experimental psychology. Could this prove to be psychology's cold fusion moment

Google is known to ask the following question in job interviews: In a country in which people only want boys every family continues to have children until they have a boy. If they have a girl, they have another child. If they have a boy, they stop. What is the proportion of boys to girls in the country?
Think you know the answer? If so, Steve Landsburg may be willing to bet you up to $5000. [more inside]

"Normal" human pregnancies last 40 weeks, right? Well, no; they can vary quite a bit by the mother's race
, number of previous children
, family history of delivering early or late
, home state
, work habits
, and even the fetus' HLA type
. So where does that "40 week" thing come from? Oh, dear.
So check out this super-nerdy pregnancy statistics
website, from an engineer mom who is collecting data from the public
(see the raw data
and auto-generated graphs
, and read the FAQ about the survey, with more cool graphs
). Looking for day-by-day
probabilities on when that baby's due? This would be your stats table with daily prediction
(adjust dates at top of page as needed). Of course, you could always shut up your constantly inquiring relatives and friends another way

'Much of what medical researchers conclude in their studies is misleading, exaggerated, or flat-out wrong.'
Dr. John P. A. Ioannidis, adjunct professor at Tufts University
School of Medicine is a meta-researcher. 'He and his team have shown, again and again, and in many different ways, that much of what biomedical researchers conclude in published studies—conclusions that doctors keep in mind when they prescribe antibiotics or blood-pressure medication, or when they advise us to consume more fiber or less meat, or when they recommend surgery for heart disease or back pain—is misleading, exaggerated, and often flat-out wrong. He charges that as much as 90 percent of the published medical information that doctors rely on is flawed. His work has been widely accepted by the medical community; it has been published in the field’s top journals, where it is heavily cited; and he is a big draw at conferences.' [more inside]
