Ukraine's grip on east loosens further; Google buys retail forecasting firm; US teachers nowhere as diverse as students

1 Ukraine’s grip on east loosens further (Lukas I Alpert in The Wall Street Journal) Fighting in eastern Ukraine grew more widespread as the Kiev government stepped up a campaign to quell a pro-Russian insurgency, with clashes reported in several cities and local defense battalions being formed in two regions that had previously been unaffected by the unrest. The widening scale of the fighting opens a more dangerous phase of a conflict that has further loosened the new Ukrainian government's grip on the east, where a move for greater autonomy from Kiev has gained strength.

The fighting in at least six eastern cities over the weekend follows the deadliest day of the weeks-old conflict on Friday, which involved clashes and a major fire in the Black Sea city of Odessa that left 46 people dead. Earlier that day, Ukrainian forces relaunched an offensive to reclaim control of the rebel stronghold of Slovyansk, surrounding the city.

Ukrainian Prime Minister Arseniy Yatsenyuk on Sunday blamed the country's security services for failing to stop Friday's violence in Odessa. Ukraine's military operation in the east drew further criticism from Russia, which has repeatedly called the use of arms against civilians a criminal act. The Ukrainian government and the West have repeatedly blamed Russia for instigating the unrest and of organizing parts of the rebellion by sending in highly trained Russian military-intelligence officers. Moscow has denied playing any role in the uprising.

2 Google buys retail forecasting firm (BBC) Internet giant Google has bought Rangespan, a UK start-up that uses data science to help retailers determine which products to sell and when. Founded in 2011 in London by former Amazon employees, Rangespan is the third UK start-up to be acquired by Google this year. On its website, Rangespan wrote: "We are very happy to announce that Rangespan is joining Google." The terms of the purchase were not made public.

Rangespan has previously helped clients such as Tesco and Asda use real-time sales data to better predict which products will be popular with customers and to better manage supply chains. Google will absorb the firm and its technology and Rangespan will no longer sell services to clients. The move comes as Google aims to expand its Google Shopping web portal and e-commerce offerings.

3 US teacher nowhere as diverse as students (San Francisco Chronicle) US teachers are nowhere near as diverse as their students. Almost half the students attending public schools are minorities, yet fewer than 1 in 5 of their teachers is nonwhite.

New studies are calling attention to this "diversity gap" at elementary and secondary schools in the US. The groups want more to be done to help teachers more accurately mirror the students in their classrooms. Teachers are always pushing their students to excel, said Kevin Gilbert, coordinator of teacher leadership and special projects for the Clinton Public School District in Clinton, Mississippi. It becomes easier for students to believe "when they can look and see someone who looks just like them, that they can relate to," said Gilbert, a member of the NEA's executive committee. "Nothing can help motivate our students more than to see success standing right in front of them."

More than minority students would benefit from a more diverse teacher corps, said Ulrich Boser, the author of the center's report. There were about 3.3 million teachers in American public elementary and secondary schools in 2012, according to a study by the National Center for Education Statistics. It said 82 percent were white, 8 percent were Hispanic, 7 percent were black and about 2 percent were Asian. Students are a different story. In 1993, minority students made up 31 percent of the public school population; it was 41 percent in 2003.
