Mapping Twitter Topic Networks: From Polarized Crowds to Community Clusters

These conversational structures differ, depending on the subject and the people driving the conversation. Six structures are regularly observed: divided, unified, fragmented, clustered, and inward and outward hub and spoke structures. These are created as individuals choose whom to reply to or mention in their Twitter messages and the structures tell a story about the nature of the conversation.

It’s called Language Immersion for Chrome by Use All Five, Inc., and this extension allows you to select a language other than your own and configure the immersion level you wish to apply to pages as you browse around the Web. Once set, certain words and/or phrases will appear highlighted and translated in your selected language, making it easy for you to pick up on that second language as you become more and more familiar with common phrases used in articles. For example, you could pick up a little extra Spanish every day by selecting Spanish and setting the immersion level down to novice.

After a while, you may opt to gradually increase this immersion level to include a larger percentage of your daily reading until eventually you have a grasp of the written language. Language Immersion for Chrome works with all 64 Google-supported languages. Other Useful Chrome Extensions. The Future of Higher Education and Cloud Computing.

‘For voters, feelings prevail over beliefs,’ Peter Mandelson writes in The Third Man.

James Meek · In the Ghost Library · LRB 3 November 2011

‘People may be torn between their head and their heart, but ultimately it is their gut feeling that is decisive: they vote for the candidate who elicits the right feelings, not necessarily the one who presents the right arguments.’ This clear and succinct expression of the idea that emotion is the true currency of democratic politics stood out on the page, and I moved to underline it, only to realise someone had done so already. Oddly, the book was spit new. It wasn’t even on paper. It was an ebook, a digital form of Mandelson’s masterwork that I’d downloaded from Amazon via the Kindle app on my iPad in the hope (futile, as it happened) of gleaning information about an obscure moment in recent British history. If the metareader is populous enough, a much noted passage will be recorded on Amazon’s ‘Most Highlighted Passages of All Time’ chart.
