SHARIA, Iraq—“Daesh hatin,daesh hatin,” rippled from villageto village across the Sinjar plainsuntil all who could flee did, purg-ing the northern Iraqi land of itsancient population.

Through the dayslong trek tosafety that followed, the Yazidisof Sinjar took that catch phrase—a mixed Arabic-Kurdish warningof the advance of Islamic mili-tants—with them. Even in the rel-ative safety of Sharia, a hamletstraddling the border with IraqiKurdistan, neighbors spread thewarning through a school court-yard housing the displaced, and

children woke up at night infright.

“My children can’t sleep,” saidSaleh al-Yas Khalaf, his six chil-dren scattered in a half-circlearound him. “They just see themen with the beards all nightlong.”

Mr. Khalaf, his two brothersand their families fled the Sinjarplains on the night of Aug. 2,when an exodus of Iraq’s Yazidiminority—Kurdish-speaking fol-lowers of a pre-Islamic faith—setoff a humanitarian catastrophe inwhich tens of thousands werestranded on a mountainside.

For his Ph.D. in astrophysics,Chris Farrell spent five yearsmining data from a giant parti-cle accelerator. Now, he spendshis days analyzing ratings forYelp Inc.’s online business-re-view site.

Mr. Farrell, 28 years old, is adata scientist, a job title thatbarely existed three years agobut since has become one of thehottest corners of the high-techlabor market. Retailers, banks,heavy-equipment makers andmatchmakers all want specialiststo extract and interpret the ex-plosion of data from Internetclicks, machines and smart-phones, setting off a scramble tofind or train them.

“People call them unicorns”because the combination of skillsrequired is so rare, said Jona-than Goldman, who ran LinkedInCorp.’s data-science team that in2007 developed the “People YouMay Know” button, which fiveyears later drove more than halfof the invitations on the profes-sional-networking platform.

Employers say the ideal can-didate must have more than tra-ditional market-research skills:the ability to find patterns inmillions of pieces of datastreaming in from differentsources, to infer from those pat-terns how customers behave andto write statistical models thatpinpoint behavioral triggers.

The U.S. military launched aseries of airstrikes in northernIraq on Friday as Americanforces returned to action in Iraqto fight a brutal Sunni extremistforce accused of attemptinggenocide in its bid to create ahard-line Islamic state.

U.S. fighter jets and armeddrones attacked targets in Iraqfor the first time since the

American troop withdrawal in2011 to try to halt the Sunni ex-tremist advance on the IraqiKurdish capital of Erbil.

The initial targets of the U.S.strikes—artillery, a group offighters and a convoy of vehi-cles—were modest. Further at-tacks expected in coming daysmay remain relatively small, al-lowing the Obama administra-tion to stick to its pledge of lim-ited involvement.

However, the U.S. faced theprospect of having to intensifythe air offensive if militants, un-deterred, continue to press theirattack against fleeing and trappedreligious minorities and the Kurd-ish-dominated city of Erbil.

The airstrikes are meant toprovide critical support forKurdish forces struggling to re-pel militants from the group

“For our parents, everythingwas much easier,” she says. “Theyhad the opportunity to start theirown life. Instead, we don’t haveany guarantees for our own fu-ture.”

Ms. Violano’s stunted adult-hood and dashed expectationsmark a generational divide be-tween younger and older Europe-ans that is challenging the Conti-nent’s dream of broad-basedprosperity.

In Pig-N-Ford Contest, Model T DriversClutch Porkers; Rival Dynasties Squeal

TILLAMOOK, Ore.—Driving incircles while holding a pig prop-erly is something that demandshewing to the rules.

The Pig-N-Ford Race has longbeen the premier event at theT i l l a m o o kCounty Fair inthis town ofabout 5,000.Each racergrabs a youngpig from a penwith one arm,crank starts aModel T Fordwith the otherand drivesaround a dirt track clutching theporker.

As the pigs join their racersthis weekend for the 2014 Pig-N-Ford finals, they will face someof the sorts of rules, rivalriesand whiff of controversy that of-ten consume motor sports.

The contest was once a free-wheeling, low-key affair, says 77-year-old George Hurliman, whostopped racing in the 1980s afterbuilding a dynasty of nine careerchampionships. “It used to be—it was more like buddy-buddy.”

That was long before theGreat CamshaftControversy of2010. MartyWalker, a UPSdriver fromnearby Sher-wood, that yeartied Mr. Hurli-man’s recordwith a ninthwin and solidi-fied his own
