It also says boys do 7% better in the maths portion of the SATs, but writes it off as a statistical illusion due to more girls doing the test (they don't know how averages work?).
I bet it wouldn't be a statistical illusion if the girls where the ones getting 7% better.
I think you misunderstood the author's logic. More college-interested girls take the test than boys. The author suggests that these extra girls are not drawn uniformly across all ability levels. These "extra" girls may be disproportionately drawn from lower ability levels, pulling down girls averages.
It's easy to imagine cultural mechanisms that could lead to this phenomena. For example, perhaps lower-ability girls are more often encouraged to apply for college than boys.
I've heard a lot of debate about Postgresql vs. MySql that doesn't need to be re-hashed for the 1000'th time. On the other hand, I haven't heard much on Oracle vs. Postgresql. I have used Postgresql quite a bit, and think it's wonderful.
What is Postgresql missing that Oracle has? What does Oracle have that Postgres is missing? When do these features matter?
Before Dan Glickman started working for the MPAA, he was at the institute of politics at Harvard's Kennedy School of Gov't. My wife and a classmate did a independent study with him about funding school lunches. She said the he was honest, excited, and insightful - one of the nicest "professors" she had ever worked with.
This has been mentioned before, but while Sec. of Agriculture under Clinton, he was the catalyst in a civil rights cleanup in the department. He had little support from anybody on this (including Clinton, most people would say). He just thought it was the right thing to do. I think that's pretty amazing these days.
People may hate the MPAA (for good reason), but it's better to have somebody like Glickman at their helm than Valenti.
