  • human brain networks represent a balance between high efficiency of information transfer and low connection cost
  • Members of the audience and other Twitter users were asked to tweet during the lecture about the concepts that were being discussed, using the hashtag #csftwitterbrain. At the end of the talk Professor Bullmore displayed the resulting image showing the interconnectivity of the hashtagged tweets, and explained how Twitter networks can be compared to the human brain network. “We found that the #twitterbrain network was somewhat like the brain network in being small-world and modular with highly connected hub nodes; however the brain network was more clustered and less efficient than the twitter network. So at first sight there were some points in common and some points of difference between these two information processing networks.”
  • “It has been intriguing to see the spectacle of watching the twitter network grow or evolve over the course of several days. And I have learnt a lot about the power of new media to engage and communicate, and the potential scientific value of using Twitter to map and measure social networks.”

      Considering that you have to be 13 to participate in most social networking sites, it should be hoped indeed that children do have a chance to engage in real life socializing before that

    Social networking websites are causing alarming changes in the brains of young users, an eminent scientist has warned. Sites such as Facebook, Twitter and Bebo are said to shorten attention spans, encourage instant gratification and make young people more self-centred. The claims from neuroscientist Susan Greenfield will make disturbing reading for the millions whose social lives depend on logging on to their favourite websites each day.

    This guest post is written by Geoff Cook, cofounder and CEO of social networking site myYearbook. Everything about Twitter is looking up these days, except for a few pesky uptime issues of course. But a number of recent reports also suggest teens are one demographic that just doesn't seem to be embracing Twitter like the rest of us. So while I'm excited to see Robert Scoble proclaims that Twitter is worth a cool $10 billion, it might be a good idea to analyze a little data to try to understand why teens just don't think Twitter is as rad as the rest of us.

    "Despite the widespread use of social media by students and its increased use by instructors, very little empirical evidence is available concerning the impact of social media use on student learning and engagement. This paper describes our semester-long experimental study to determine if using Twitter - the microblogging and social networking platform most amenable to ongoing, public dialogue - for educationally relevant purposes can impact college student engagement and grades. A total of 125 students taking a first year seminar course for pre-health professional majors participated in this study (70 in the experimental group and 55 in the control group). With the experimental group, Twitter was used for various types of academic and co-curricular discussions. Engagement was quantified by using a 19-item scale based on the National Survey of Student Engagement. To assess differences in engagement and grades, we used mixed effects analysis of variance (ANOVA) models, with class sections nested within treatment groups. We also conducted content analyses of samples of Twitter exchanges. The ANOVA results showed that the experimental group had a significantly greater increase in engagement than the control group, as well as higher semester grade point averages. Analyses of Twitter communications showed that students and faculty were both highly engaged in the learning process in ways that transcended traditional classroom activities. This study provides experimental evidence that Twitter can be used as an educational tool to help engage students and to mobilize faculty into a more active and participatory role."

    Twitter has changed from being a tool most people thought is simply yet another way for people on the Internet to waste time to a platform for social change, social networking and dare I say it even business. One of the aspects that Twitter has been lacking is an accessible interface to the service. Thankfully Dennis Lembrée is changing all this. Schalk Neethling sat down with Dennis to learn more about Accessible Twitter, the problems he faces in creating it and what the future will hold.

  • as Viktor Mayer-Schönberger argues convincingly in his book Delete: The Virtue of Forgetting in the Digital Age (Princeton University Press, 2009), the costs of such powerful collective memory are often higher than we assume.
  • "Total recall" renders context, time, and distance irrelevant. Something that happened 40 years ago—whether youthful or scholarly indiscretion—still matters and can come back to harm us as if it had happened yesterday.
  • an important "third wave" of work about the digital environment. In the late 1990s and early 2000s, we saw books like Nicholas Negroponte's Being Digital (Knopf, 1995) and Howard Rhein-gold's The Virtual Community: Homesteading on the Electronic Frontier (Addison-Wesley, 1993) and Smart Mobs: The Next Social Revolution (Perseus, 2002), which idealistically described the transformative powers of digital networks. Then we saw shallow blowback, exemplified by Susan Jacoby's The Age of American Unreason (Pantheon, 2008).

  • For most of human history, forgetting was the default and remembering the challenge.
  • Chants, songs, monasteries, books, libraries, and even universities were established primarily to overcome our propensity to forget over time. The physical and economic limitations of all of those technologies and institutions served us well. Each acted not just as memory aids but also as filters or editors. They helped us remember much by helping us discard even more.

      Excellent point, well made.
  • Just because we have the vessels, we fill them.
  • Even 10 years ago, we did not consider that words written for a tiny audience could reach beyond, perhaps to someone unforgiving, uninitiated in a community, or just plain unkind.
  • Remembering to forget, as Elvis argued, is also essential to getting over heartbreak. And, as Jorge Luis Borges wrote in his 1942 (yep, I Googled it to find the date) story "Funes el memorioso," it is just as important to the act of thinking. Funes, the young man in the story afflicted with an inability to forget anything, can't make sense of it. He can't think abstractly. He can't judge facts by relative weight or seriousness. He is lost in the details. Painfully, Funes cannot rest.
  • Our use of the proliferating data and rudimentary filters in our lives renders us incapable of judging, discriminating, or engaging in deductive reasoning. And inductive reasoning, which one could argue is entering a golden age with the rise of huge databases and the processing power needed to detect patterns and anomalies, is beyond the reach of lay users of the grand collective database called the Internet.
  • the default habits of our species: to record, retain, and release as much information as possible
  • Perhaps we just have to learn to manage wisely how we digest, discuss, and publicly assess the huge archive we are building. We must engender cultural habits that ensure perspective, calm deliberation, and wisdom. That's hard work.
  • we choose the nature of technologies. They don't choose us. We just happen to choose unwisely with some frequency

  • Google compresses, if not eliminates, temporal context. This is likely only to exacerbate the existing problem in politics of taking one's statements out of context. A politician whose views on a subject have evolved quite logically over decades in light of changing knowledge and/or circumstances is held up in attack ads as a flip-flopper because consecutive Google entries have him/her saying two opposite things about the same subject -- and never mind that between the two statements, the Berlin Wall may have fallen or the economy crashed harder than at any other time since 1929.

  • Shashi Tharoor, the country's junior minister for foreign affairs, has become a major national celebrity thanks to his tweets, the candor of some of which has got him into trouble with the fustier, unwired elements of the cabinet to which he belongs. Tharoor has nearly 700,000 followers, putting him in the top 10 of the world's tweeting politicians. (He is almost certainly the only one who writes every tweet himself.)

  • "Have our brains become so desensitized by a 24/7, all-you-can-eat diet of lurid flickering images that we've lost all perspective on appropriateness and compassion?" they asked. A 2007 study of 18 to 23-year-olds found they were less able to identify expressions of emotion after playing violent video games. And, while Dr. Rosen's study found that can help people relate better, it also found that excessive social networking makes some teens more prone to aggression, mania, anxiety, and depression.

  • This is morning in America in the Internet age. After six to eight hours of network deprivation — also known as sleep — people are increasingly waking up and lunging for cellphones and laptops, sometimes even before swinging their legs to the floor and tending to more biologically urgent activities.
  • The surge of early risers is reflected in online and wireless traffic patterns. Internet companies that used to watch traffic levels rise only when people booted up at work now see the uptick much earlier.

  • WASHINGTON – As the Pentagon warns of the security risks posed by social networking sites, newly released government documents show the military also uses these Internet tools to monitor and react to coverage of high-profile events. The Air Force tracked the instant messaging service Twitter, video carrier YouTube and various blogs to assess the huge public backlash to the Air Force One flyover of the Statue of Liberty this spring, according to the documents. And while the attempts at damage control failed — "No positive spin is possible," one PowerPoint chart reads — the episode opens a window into the tactics for operating in a boundless digital news cycle.

  • The issue of aliases is at the heart of a complaint stemming for the Army Corps of Engineers' performance in New Orleans before and after Hurricane Katrina. On Tuesday, Sen. Mary Landrieu, D-La., asked the Pentagon inspector general to examine allegations that Corps employees posed as ordinary citizens and posted comments on a New Orleans web site defending the organization from criticism following the disaster. Jon Donley, former editor of NOLA.com, said in a June 9 affidavit that there were as many as 20 registered users who developed a pattern of not only defending the Corps, but at times being "overtly abusive" to any critics. He said he was able to trace their posts to a Corps Internet address. Ken Holder, a spokesman for Corps' New Orleans District, said it will cooperate with any investigation.

  • To those who Twitter, the reporter who investigates a story before offering it to the public must also seem tediously ruminant. On Twitter, the notes become the story, devoid of even five minutes of reflection on the writer's way to the computer. I can see that there are times —an airplane landing in the Hudson, a presidential election in Iran—when this type of impromptu journalism becomes a necessity, and an exciting one at that. Luckily, reporters still exist to make sense of information bytes and expand upon them for readers—but for how much longer? I worry that microblogging cheats my students out of their trump card: a mindful attention to the subject in front of them, so that they can capture its sights and sounds, its smells and tactile qualities, to share with readers. How can Twittering stories from laptops and phones possibly replace the attentive journalist who tucks a digital recorder artfully under a notepad, pencil behind one ear, and gives full attention to the subject at hand?
  • I went home after the lecture and—hypocritically, I admit—updated my Facebook status and my blog to declare how much I despise Twitter.
  • Twitter serves as a source of links to longer news stories.

      Which is one of its main uses in journalism. As Jay Rosen (@jayrosennyu) and others have put it, through services like Twitter and, indeed, Diigo we edit the web for one another. We can see it as acting as human filters, intelligent gatherers and sifters of information for the various networks in which we are nodes.

  • Part of my interest in this turn to Twitter comes from disappointment with most university press blogs, which often seem more like PR vehicles than genuine blogs with discussion, disagreement, expressions of real enthusiasm or curiosity or whatever. Reading very many of them at one sitting feels like attending a banquet where you are served salt-free soda crackers and caffeine-free Mountain Dew that's gone flat.By contrast, university-press publicists seem more inclined to experiment and to follow tangents with Twitter than they do on their own official websites. They link to material they have posted at the press’s blog, of course – but also to news and commentary that may be only obliquely related to the books in their catalog. It’s as if they escape from beneath the institutional superego long enough to get into the spirit of blogging, proper.
  • The range and the interest of Duke's tweets make its presence exemplary, in my opinion. Between drafting and rewriting this column, for example, I followed Duke's tweets to a newspaper article about whether or not English was approaching one million words, a blog post about rock songs cued to Joyce's Ulysses, and the Twitter feed of Duke author Negar Mottahedeh, who has been posting about events in Iran.
  • She then makes a point that bears stressing given how often university-press blogs tend to be coated in institutional gray: “I think that any kind of social networking needs to have a personality tied to it in order for it to be successful. Also, I think you really need to participate in the media in order for it to be successful. We ask people for questions and opinions, offer giveaways sometimes. My main goal is to try to get people talking -- either with me or with each other about our books and authors.... You can't just provide information or news feeds to reviews and articles about your books. Involving the Press in what is going, contributing to the various discussions, and asking (and answering) questions is really the way to grow your following.”
