Q: Russian election officials on Monday formally barred  Russian opposition leader Alexei Navalny  from running for president  prompting calls from  him  for a boycott of next year's vote.
 Navalny  is implicitly barred from running for office because of a conviction in a fraud case which has been viewed as political retribution.  He  could have run if  he  was given a special dispensation or if  his  conviction was cancelled.
 Incumbent Vladimir Putin  is set to easily win a fourth term in office in the March 18 election  with  his  approval ratings topping 80%.
 Putin  foe clears first step in bid for Russian presidency
Over the past year   Navalny  has mounted a grassroots campaign which reached out to the most remote corners of  Putin 's heartland.
 Navalny   41  is the most serious challenger that  Putin  has faced in all  his  years in power  and the court cases against  him  have been widely seen as a tool to keep  him  from running for office.
In a pre-recorded video message that was released minutes after the Election Commission handed down the decision  Navalny called on  his  supporters to boycott the vote.
"The procedure that we're invited to take part is not an election "  he  said. "Only Putin and the candidates  he  has hand-picked are taking part in it."
Central Election Commission chief Ella Pamfilova told  Navalny  ahead of its vote to bar him that "maybe we would be interested if you were running " but said the conviction doesn't allow the commission to put him on the ballot.
Speaking before the vote   Navalny  told the commission that  their  decision to bar him would be a vote "not against me  but against 16 000 people who have nominated me  against 200 000 volunteers who have been canvassing for me."
The involvement of Ksenia Sobchak  a 36-year-old star TV host  could raise public interest in the race. While Sobchak has denied colluding with the Kremlin  she could attract some of  Navalny 's supporters and help boost attendance.
Sobchak criticized  Navalny 's call for boycotting the vote  saying Monday that the "election is the only way to change something  and boycotting them is inefficient and harmful."

Q: Dance troupe spotlights Mexico ' s native son  Limon
 "How many of you know Jose Limon?" Audience members looked around sheepishly as just a few raised their hands.
 Revered by dance aficionados the world over as one of the iconic figures of modern dance  Limon is largely unknown in his native Mexico.
 "I must say I was a bit shocked to hear how little recognition Limon gets in his own country " said Gabriela Poler-Buzali  the Jose Limon Dance Foundation's executive director.
 Held in a sprawling museum  the show included solos by two of the company's principal dancers  who flung themselves across the diminutive stage with Limon's trademark controlled abandon.
 Limon himself was born in Culiacan  in the northwestern state of Sinaloa  in 1908  two years before Mexico's bloody and chaotic 1910-1917 Revolution. When he was 7 years old  Limon's family fled to the United States.
 Although he spent most of his life in the United States  his early years in the midst of the Mexican Revolution deeply marked him. War and conflict are dominant themes in many of his works  including "Missa Brevis."
 As a young man  he moved to New York to study painting but fell in love with dance  founding his own company after serving in World War II. He pioneered a dramatic  narrative-driven choreography style and was among the first to push male dancers to center stage. Along with Graham  he's widely considered among the key figures of 20th-century dance.
