Xerox is one of America's most venerable companies. Founded in 1906, its name is virtually synonymous with "photocopy."

But in recent years, in an era of email and paperless offices, Xerox has struggled to stay relevant. Today, the company is trying to turn itself around and thrive in the digital age.

Leading Xerox through that transformation is Ursula Burns, a woman who has undergone tremendous change in her own life. Burns, 53, grew up in New York City's Lower East Side, an area she has described as a tough, drug-infested ghetto.

Sanctions have not often worked to get governments to change their behavior, but Iran may prove to be an exception. The country depends on income from oil sales, and the oil sector is highly vulnerable to sanctions.

The United States has stopped buying Iranian oil, and the European Union is set to do so at the end of next month. There are sanctions on Iran's central bank and punishments for companies that help Iran ship its oil.

Jamie Webster, an oil market analyst at PFC Energy, says Iran's oil exports — normally about 2.5 million barrels a day — are in serious jeopardy.

European stock markets have rallied in anticipation of an informal summit of European Union leaders Wednesday in Brussels. A major policy pivot is expected to address the eurozone's debts and deficits crisis.

Up to now, European leaders have emphasized austerity, and that has cost some of them their jobs. The new approach is likely to focus on the same kind of growth President Obama has pursued in the United States — where Democrats and Republicans are drawing opposite conclusions from the euro crisis.

It's the climax of the hockey and basketball seasons, but both have potential playoff visibility problems. Let me explain.

OK, the NBA first. As you know, basketball is the most individualized, celebrity-ized team game. Like movie stars, the best players are known by their first names: LeBron, Kobe, Dirk. Every basketball superstar wants to take his talents to a hot-dog, big-time market. Or at least marry a Kardashian.

Tonight, when Ryan Seacrest announces who has won the 11th season of American Idol — when the confetti falls and Jennifer Lopez sheds a perfect dewy teardrop and Randy Jackson's thought bubble explodes with "Dude, that was a moment moment MOMENT" and Steven Tyler purses his immortal lips in that vampire-connoisseur way he does, smelling the perfume of another sweet young victory — I will be out to dinner with friends, far from the agony and ecstasy finalists Jessica Sanchez and Phi

There are many ways to find a lost or stolen cellphone. You can call the number and see who answers; you can use "Find My Phone" apps that track your phone's GPS. Or, if your camera phone automatically posts photos to your account in "the cloud," you can simply watch your photo feed and look for clues in the strange new images that start popping up. Just be prepared to see anything — like scenes from a cruise ship.

It seems there's not a month that goes by that Maricopa (Ariz.) County Sheriff Joe Arpaio isn't involved in one controversy or another.

As we've reported, Arpaio is already facing a federal civil rights lawsuit.

But now there's news that Arpaio is using public money on his quest to investigate President Obama's birth certificate. Both the Arizona Republic and Honolulu Star Advertiser report that Arpaio sent his deputy, Brian Mackiewcz, to Hawaii in part because of what Arpaio said were "security issues," related to the investigation.
