Digital Divides and Bridges: Technology Use Among Youth | Pew Research Center's Internet & American Life Project
Digital Divides and Bridges: Technology Use Among Youth | Pew Research Center's Internet & American Life Project:
In her talk, Amanda focused on bringing together data that highlights the demographic differences among groups of youth in their adoption, use, and experiences with technology and social media. While such data may have illustrated what was called a “digital divide” in the past, it now highlights a variety of digital differences among groups of youth.

Google Privacy Inquiries Get Little Cooperation - NYTimes.com
Google Privacy Inquiries Get Little Cooperation - NYTimes.com:
After months of negotiation, Johannes Caspar, a German data protection official, forced Google to show him exactly what its Street View cars had been collecting from potentially millions of his fellow citizens. Snippets of e-mails, photographs, passwords, chat messages, postings on Web sites and social networks — all sorts of private Internet communications — were casually scooped up as the specially equipped cars photographed the world’s streets.

Big Data Troves Stay Forbidden to Social Scientists - NYTimes.com
Big Data Troves Stay Forbidden to Social Scientists - NYTimes.com:
It is “big data,” the vast sets of information gathered by researchers at companies like Facebook, Google and Microsoft from patterns of cellphone calls, text messages and Internet clicks by millions of users around the world. Companies often refuse to make such information public, sometimes for competitive reasons and sometimes to protect customers’ privacy. But to many scientists, the practice is an invitation to bad science, secrecy and even potential fraud.
The issue came to a boil last month at a scientific conference in Lyon, France, when three scientists from Google and the University of Cambridge declined to release data they had compiled for a paper on the popularity of YouTube videos in different countries.
The chairman of the conference panel — Bernardo A. Huberman, a physicist who directs the social computing group at HP Labs here — responded angrily. In the future, he said, the conference should not accept papers from authors who did not make their data public. He was greeted by applause from the audience.
Last year the National Science Foundation said that researchers who receive its funds would be “expected” to share data with other researchers.
Many scientists agree that this is as it should be.
“The obvious answer is that there needs to be more access to data,” said Alex Pentland, director of the Human Dynamics Laboratory at M.I.T. “That is beginning to happen as governments and industry realize that they need to better understand the promise and limits of big data; for instance, we will be announcing a huge, multicountry release of phone data soon.”

Schools Go Into the 'Cloud' to Embrace the Popularity of Social Media - NYTimes.com
Schools Go Into the 'Cloud' to Embrace the Popularity of Social Media - NYTimes.com:
The newest catchphrase in online education is social learning.
Several start-up companies have begun offering cloud-based platforms that combine education and social media. Companies like Teamie, based in Singapore, provide software that lets teachers create, share and manage academic content, and also let students collaborate on assignments on platforms that are similar to the “walls” used on Facebook.

CNN transcript collection, 2000-2012:
Thanks to the Internet Archive and CNN, thirteen years of transcripts, about a gigabyte compressed, is available to download as one file.
For over a decade, CNN (Cable News Network) has been providing transcripts of shows, events and newscasts from its broadcasts. The archive has been maintained and the text transcripts have been dependably available at transcripts.cnn.com. This is a just-in-case grab of the years of transcripts for later study and historical research.
