Under activist investor pressure, McGraw-Hill to split into two listed companies

The breakup of the mini-conglomerate follows public demands starting in July from the Ontario Teacher's Pension Fund and hedge fund Jana Partners LLC for a broad reorganization. The activists suggested breaking up the company into more than two pieces to highlight the value of its individual equities, commodities and financial analytics units.
These activist investors comprise about a 15% (so far) stake in the company. McGraw-Hill, in case you didn't know, is a major publisher of "integrated math" and "Everyday Math" books.

Activist investing is an interesting strategy in educational reform; in this case it appears to be the unlikely alliance of teachers (with educational interests) and a hedge fund (with a financial interest). Even with a small, but significant stake, you can nucleate other shareholders around you and force management votes and proxy battles, and cause massive headaches for management, who will often have a large risk of being voted out.

Even if voting out does not occur, management will often make such concessions to activists as reform of their company policies and educational products, or even various monetary "greenmails"; activists can then use this money to multiply their leverage against other targeted companies.

On 9/11, Jimmy's teacher called and told me to come pick him up. The high school was in chaos, she said; they'd had word that a former member of the staff had died in one of the planes, and teachers and kids were crying. Jimmy, then 14, was big and difficult and had attended the school for just 5 days, the first severely autistic student ever to enroll. His transition was going badly, and there was now no chance they would be making headway on that front today. 

When I got there, the teacher told me her babysitter had called: there'd been an attack on Fort Smith, up near her house. I'd never heard of Fort Smith, and I had no idea where it was, close or far. "Pick up all your kids," the teacher said. So I did.

Christopher was in the lunch room when his name was announced along with the name of our neighbor's son, Christopher's friend. There was a mix-up about who the other boy's teacher was, so Christopher told the grownups the right teacher's name, and then he was sent out to me.

I have no memory of greeting him that day. Where were we? In the school lobby? On the steps out front? Those moments are gone. My memories of 9/11 are like the movie Inception, where one of the signs the characters are dreaming is that they don't know how they got wherever it is they are now. That's 9/11 for me. In one memory I'm standing in front of the high school talking to Jimmy's teacher; in the next I'm walking with Christopher on the sidewalk at the far end of the school parking lot, the end close to my friend K's house, trying to think how to tell him about the airplanes hitting the towers and the towers falling down and realizing I should have come up with a plan about how to do this before I got here. Instead, I'm winging it.

In the next memory, I can hear myself saying, "Something bad happened," and after that there's another jump cut, and now Christopher is asking me anxiously what the country can do. I don't have a plan for handling this part of the conversation, either, so Christopher, sensing he's on his own, is trying to figure it out for himself.

We go back and forth a little bit about the things America could do, nothing I say providing the slightest reassurance or comfort, until finally he asks: "Do they have any really tall buildings?" Meaning: Do they have any really tall buildings we can knock down? His little face, ringed with curls, is tense and worried, but his voice is hopeful. He is seven, he has been in second grade for five days, and if we have lost two buildings, then it is right for them to lose two buildings, too. But the buildings have to be really tall.

"No," I say, "they don't," and he looks stricken. I am stricken, too. Something bad has happened.

Later on, that day or another day, Christopher worries that something bad will happen to the Statue of Liberty, too. What if the terrorists crash an airplane into the Statue?

I wonder what was my answer. Something with too many words, I'm sure. They probably won't try to hurt the Statue, but even if they do try the army is watching, and they won't let any planes crash into the Statue, etc., etc. My point being: the Statue is safe. Also, we are safe.

But Christopher isn't listening. He has come up with his own answer.

"If the terrorists crash into the Statue of Liberty," he says, "it will be OK. The French are so nice, they will give us another one."

It is the right answer, and he doesn't worry about the Statue again.

The meaning of an expression?

I have a question about an Integrated Algebra homework assignment:
In 3-10, state the meaning of each expression in part a and in part b, and simplify the expression in each part.
The first two problems:
3.  a.  20 + (6+1)    b.  20 + 6 + 1
4.  a.  18 - (4 + 3)   b.  18 - 4 + 3 
What does "state the meaning" mean?  I suspect it means to write the equation in words, as explained in this Yahoo Answers response offered by a teacher.

Also, I noticed that every homework exercise in the textbook has a "Writing About Mathematics" section.  I wonder if the teacher will correct all the writing assignments.

Lots of writing ahead.

The book is Amsco's Integrated Algebra for New York State.
