"Starting today, we're making this feature even more useful by removing the requirement that guests have a Google account in order to join a Hangouts video call. Here's how it works: guests without a Google account who have been provided with the video call link by the organizer will be asked to provide their name and then request to join the call."

"Last month in a blog post titled "Better Than a Textbook?", I noted that some faculty find it easier to think about the massive open online courses (MOOCs) provided by vendors like Coursera as "super-textbooks" than as actual courses. Earlier this month, Vanderbilt computer science professor Doug Fisher wrote a guest post for the blog ProfHacker titled "Warming up to MOOCs," in which he described his experiments in using MOOCs in this fashion."

When deciding what to filter, the IT department considers two questions: 1) Is there a relevant ­educational need for the site? and 2) Does the site potentially expose students to inappropriate material? "The toughest area to assess is social media," Vomastek continues. "Right now, we block Facebook and Twitter during the school day but ­allow users of our guest wireless network to access them during non-school hours. There's no one choice that will make everybody happy."

They chose their rooms and paid for everything online. But their beds were provided by private individuals, rather than a hotel chain. Hosts and guests were matched up by Airbnb, a firm based in San Francisco. Since its launch in 2008 more than 4m people have used it-2.5m of them in 2012 alone. It is the most prominent example of a huge new "sharing economy", in which people rent beds, cars, boats and other assets directly from each other, co-ordinated via the internet.

"I love being a scholar, but one thing that really depresses me about research is that so much of what scholars produce is rendered inaccessible to so many people who might find it valuable, inspiring, or thought-provoking. This is at the root of what drives my commitment to open-access. When Zizi Papacharissi asked Nancy Baym and I if we'd be willing to guest edit the Journal of Broadcasting & Electronic Media (JOBEM), we agreed under one condition: the issue had to be open-access (OA). Much to our surprise and delight, Taylor and Francis agreed to "test" that strange and peculiar OA phenomenon by allowing us to make this issue OA. Nancy and I decided to organize the special issue around "socially mediated publicness," both because we find that topic to be of great interest and because we felt like there was something fun about talking about publicness in truly public form. We weren't sure what the response to our call would be, but were overwhelmed with phenomenal submissions and had to reject many interesting articles. "

Amid continued debate over whether or not Sochi is prepared to host the 2014 Olympics, which begins Thursday, reporters from around the world are starting to check into local hotels - to their apparent grief. Some journalists arriving in Sochi are describing appalling conditions in the housing there, where only six of nine media hotels are ready for guests. Hotels are still under construction. Water, if it's running, isn't drinkable. One German photographer told the AP over the weekend that his hotel still had stray dogs and construction workers wandering in and out of rooms.

"When doing a Google+ Hangout, it's just good form to introduce yourself to viewers and other participants. Insert a news anchor type name bar under your image by setting up the Google+ Hangout Lower Third App. For a regular Hangout where you might have guests who don't know each other, it's fine to ask that everyone install their Lower Third App."
