The United Nations Educational, Scientific and Cultural Organization (UNESCO) is an international organization founded in 1945 to contribute to peace and security by promoting international collaboration through education, science, and culture.
Victoria Nuland, a State Department spokeswoman, said that American contributions to Unesco, including $60 million scheduled for this month, would not be paid.
UNESCO has declared that:
It is well-known that funding from our largest contributor, the United States, may be jeopardized. I believe it is the responsibility of all of us to make sure that UNESCO does not suffer unduly as a result.
In a world with 7,000,000,000 people, UNESCO develops key programmes to promote literacy, education, science, and technology. Eventually, I believe the USA will start contributing again to UNESCO, but in the mean time I think we have to collaborate, not only with words but also with funds so that the work of this organization can continue. Please, it will take just a minute of your time to make a donation today »»
Want to monitor an earthquake, track political activity or predict the ups and downs of the stock market? Researchers have found a bonanza of real-time data in the torrential flow of Twitter feeds.
When the magnitude 8.8 Chilean earthquake hit last year, researchers found that on Twitter the truth often won out over misinformation. "When a rumor is true, it spreads faster," said computer analyst Barbara Poblete at the University of Chile in Santiago.
Ms. Poblete and her colleagues analyzed how survivors of the earthquake used the messaging service in lieu of more conventional communications that had been knocked out. They discovered that in the crisis, Twitter crowds reflexively sorted facts from falsehoods, exercising a collective wisdom on the fly. She found enough measurable differences in language, citations and posting patterns to devise a way to assess the credibility of Twitter texts automatically, with an accuracy of about 70%.
"The network itself can provide a filter for valid information," Ms. Poblete said.
