As a related study describes, Twitter has come to play a crucial role in the way that news functions during events like the Egyptian revolution—like an overloaded newswire filled with everything from breaking news to rumor and everything in between.The evolution of what media theorist Jeff Jarvis and others have called "networked journalism" has made the business of news much more chaotic, since it now consists of thousands of voices instead of just a few prominent ones who happen to have the tools to make themselves heard. If there is a growth area in media, it is in the field of "curated news," where real-time filters verify and redistribute the news that comes in from tens of thousands of sources, and use tools like Storify to present a coherent picture of what is happening on the ground.One of the additional points the study makes is that the personal Twitter accounts belonging to journalists were far more likely to be retweeted or engaged with by others than official accounts for the media outlets they worked for. The point here is one we have tried to make repeatedly: Social media are called social for a reason. They"re about human beings connecting with other human beings around an event, and the more that media outlets try to stifle the human aspect of these tools—through repressive social-media policies, for example—the less likely they will be to benefit from using them.Another benefit of a distributed or networked version of journalism is one sociologist Zeynep Tufekci has made in the course of her research into how Twitter and other social tools affected the events in Tunisia, Egypt, and elsewhere. As she wrote in a recent blog post, one of the realities of mainstream media is what is often called "pack journalism": the kind that sees hundreds of journalists show up for official briefings by government or military sources, but few pursue their own stories outside the official sphere. Tufekci says social media and "citizen journalism" can be a powerful antidote to this kind of process, and that"s fundamentally a positive force for journalism.As we look at the way news and information flows in this new world of social networks, and what Andy Carvin has called "random acts of journalism" by those who may not even see themselves as journalists, it"s easy to get distracted by how chaotic the process seems, and how difficult it is to separate the signal from the noise. But more information is better-even if it requires new skills on the part of journalists when it comes to filtering that information—and journalism, as Jay Rosen has pointed out, tends to get better when more people do it.

The film-awards season, which reaches its tearful climax with the Oscars next week, has long been only loosely related to the film business. Hollywood is dedicated to the art of funneling teenagers past popcorn stands, not art itself. But this year"s awards are less relevant than ever. The true worth of a film is no longer decided by the crowd that assembles in the Kodak Theatre—or, indeed, by any American. It is decided by youngsters in countries such as Russia, China and Brazil.Hollywood has always been an international business, but it is becoming dramatically more so. In the past decade total box-office spending has risen by about one-third in North America while more than doubling elsewhere. Thanks to Harry Potter, Sherlock Holmes and "Inception", Warner Bros made $2.93 billion outside North America last year, smashing the studio"s previous record of $2.24 billion. Falling DVD sales in America, by far the world"s biggest home-entertainment market, mean Hollywood is even more dependent on foreign punters.The rising foreign tide has lifted films that were virtually written off in America, such as "Prince of Persia" and "The Chronicles of Narnia: the Voyage of the Dawn Treader". Despite starring the popular Jack Black, "Gulliver"s Travels" had a disappointing run in North America, taking $42m at the box office so far. But strong turnout in Russia and South Korea helped it reach almost $150m in sales elsewhere. As a result, it should turn a profit, says John Davis, the film"s producer.The growth of the international box office is partly a result of the dollar"s weakness. It was also helped by "Avatar", and eco-fantasy that made a startling $2 billion outside North America. But three things are particularly important: a cinema boom in the emerging world, a concerted effort by the major studios to make films that might play well outside America and a global marketing push to make sure they do.Russia, with its shrinking teenage population, is an unlikely spot for a box-office boom. Yet cinema-building is proceeding apace, and supply has created demand. Last year 160m cinema tickets were sold in Russia—the first time in recent years that sales have exceeded the country"s population. Ticket prices have risen, in part because the new cinemas are superior, with digital projectors that can show 3D films. The big Hollywood studios are muscling domestic film-makers aside. In 2007 American films made almost twice as much at the Russian box office as domestic films—8.3 billion roubles ($325m) compared with 4.5 billion. Last year the imported stuff made some 16.4 billion roubles: more than five times as much as the home-grown product, estimates Movie Research, a Moscow outfit. Earlier this month Vladimir Putin, Russia"s Prime Minister, said the government would spend less money supporting Russian film-makers and more on expanding the number of screens. What is the main idea of Paragraph 5
For the moment, mind-reading is still science fiction. But that may not be true for much longer. Several lines of inquiry are converging on the idea that the neurological activity of the brain can be decoded directly, and people"s thoughts revealed without being spoken.Just imagine the potential benefits. Such a development would allow both the fit and the disabled to operate machines merely by choosing what they want those machines to do. It would permit the profoundly handicapped to communicate more easily than is now possible even with the text-based speech engines used by the likes of Stephen Hawking. It might unlock the mental prisons of people apparently in comas, who nevertheless show some signs of neural activity. For the able-bodied, it could allow workers to dictate documents silently to computers simply by thinking about what they want to say. The most profound implication, however, is that it would abolish the ability to lie.Who could object to that You will not bear false witness. Tell the truth, and shame the Devil. Transparency, which speaks for honesty in management, is put forward as the answer to most of today"s evils. But honestly speaking, the truth of the matter is that this would lead to disaster, for lying is at the heart of civilization. People are not the only creatures who lie. Species from squids to chimpanzees have been caught doing it from time to time. But only human beings have turned lying into an art. Call it diplomacy, public relations or simple good manners: lying is one of the things that make the world go round.The occasional untruth makes domestic life possible, is essential in the office and forms a crucial part of parenting. Politics might be more entertaining without lies—"The prime minister has my full support" would be translated as, "If that half-wit persists in this insane course we"ll all be out on our ears"—but a party system would be hard to sustain without the semblance of loyalty that dishonesty permits.The truly scary prospect, however, is the effect mind-reading would have on relations between the state and the individual. In a world in which the authorities could peep at people"s thoughts, speaking truth to power would no longer be brave: it would be unavoidable. Information technology already means that physical privacy has become a scarce commodity. Websites track your interests and purchases. Mobile phones give away your location. Video cameras record what you are up to. Lose mental privacy as well, and there really will be nowhere. Which of the following is true according to Paragraph 1

This year has turned out to be a surprisingly good one for the world economy. Global output has probably risen by close to 5%, well above its trend rate and a lot faster than forecasters were expecting 12 months ago. Most of the dangers that frightened financial markets during the year have failed to materialize. China"s economy has not suffered a hard landing. America"s mid-year slowdown did not become a double-dip recession. Granted, the troubles of the euro area"s peripheral economies have proved all too real. Yet the euro zone as a whole has grown at a decent rate for an ageing continent, thanks to oomph from Germany, the fastest-growing big rich economy in 2010.The question now is whether 2011 will follow the same pattern. Many people seem to think so. Consumer and business confidence is rising in most parts of the world; global manufacturing is accelerating; and financial markets are buoyant. The MSCI index of global share prices has climbed by 20% since early July. Investors today are shrugging off news far more ominous than that which rattled them earlier this year, from the soaring debt yields in the euro zone"s periphery to news of rising inflation in China.Earlier this year investors were too pessimistic. Now their breezy confidence seems misplaced. To oversimplify a little, the performance of the world economy in 2011 depends on what happens in three places: the big emerging markets, the euro area and America. These big three are heading in very different directions, with very different growth prospects and contradictory policy choices. Some of this divergence is inevitable: even to the casual observer, India"s economy has always been rather different from America"s. But new splits are opening up, especially in the rich world, and with them come ever more chances for friction.Begin with the big emerging markets, by far the biggest contributors to global growth this year. Where it can, foreign capital is pouring in. Isolated worries about asset bubbles have been replaced by a fear of broader overheating. With Brazilian shops packed with shoppers, inflation there has surged above 5% and imports in November were 44% higher than the previous year.Cheap money is often the problem. Though the slump of 2009 is a distant memory, monetary conditions are still extraordinarily loose, thanks, in many places, to efforts to hold down currencies. This combination is unsustainable. To stop prices accelerating, most emerging economies will need tighter policies next year. If they do too much, their growth could slow sharply. If they do too little, they invite higher inflation and a bigger tightening later. Either way, the chances of a macroeconomic shock coming from the emerging world are rising steeply. By saying "now their breezy confidence seems misplaced", the author means that ______.
