Geeks at the Beach: 10 Summer Reads About Technology and Your Life - Technology - The C... - 0 views

  • we're so excited about checking e-mail and Facebook that we're neglecting face-to-face relationships, but that it's not too late to make some "corrections" to our high-tech habits. It's time to turn off the BlackBerry for a few minutes and set some ground rules for blending cyberspace with personal space.
  • examples such as Wikipedia and a ride-sharing Web site as proof that "the harnessing of our cognitive surplus allows people to behave in increasingly generous, public, and social ways."
  • the transformative potential of the Internet, as more people use their free time in active, collaborative projects rather than watching television.

  • Mr. Vaidhyanathan, a professor of media studies and law at the University of Virginia and frequent contributor to The Chronicle Review, reminds readers that they aren't consumers of Google's offerings. Rather, their use of Google's services is the product it sells to advertisers. Both books look at the continuing evolution of the Google Books settlement as a key test of how far the company's reach could extend and a sign of how the perception of Google has changed from that of scrappy upstart with a clever motto, "Don't be evil," to global behemoth accused by some of being just that.
  • Is the Internet on its way to getting monopolized? That question underlies Tim Wu's The Master Switch. The eccentric Columbia Law School professor—he's known to dress up as a blue bear at the annual Burning Man festival—recounts how ruthless companies consolidated their power over earlier information industries like the telephone, radio, and film. So which tech giant seems likely to grab control of the net?
  • it feels like we're perpetually on the verge of a tipping point, when e-books will overtake print books as a source of revenue for publishers. John B. Thompson, a sociologist at the University of Cambridge, analyzes the inner workings of the contemporary trade-publishing industry. (He did the same for scholarly publishing in an earlier work, Books in the Digital Age.) Mr. Thompson examines the roles played by agents, editors, and authors as well as differences among small, medium, and large publishing operations, and he probes under the surface of the great digital shift. We're too hung up on the form of the book, he argues: "A revolution has taken place in publishing, but it is a revolution in the process rather than a revolution in the product."
  • technology is actually doing far more to bolster authoritarian regimes than to overturn them, writes Evgeny Morozov in this sharp reality check on the media-fueled notion that information is making everybody free. Mr. Morozov, a visiting scholar at Stanford University, points out that the Iranian government posted "most wanted" pictures of protesters on the Web, leading to several arrests. The Muslim Brotherhood blogs actively in Egypt. And China pays people to make pro-authority statements on the Internet, paying a few cents for each endorsement. The Twitter revolution, in this book, is "overblown and completely unsubstantiated rhetoric."
  • Internet is rewiring our brains and short-circuiting our ability to think. And that has big consequences for teaching, he told The Chronicle last year: "The assumption that the more media, the more messaging, the more social networking you can bring in will lead to better educational outcomes is not only dubious but in many cases is probably just wrong."

Jonathan Stray » Measuring and improving accuracy in journalism - 0 views

  • Accuracy is a hard thing to measure because it’s a hard thing to define. There are subjective and objective errors, and no standard way of determining whether a reported fact is true or false
  • The last big study of mainstream reporting accuracy found errors (defined below) in 59% of 4,800 stories across 14 metro newspapers. This level of inaccuracy — where about one in every two articles contains an error — has persisted for as long as news accuracy has been studied, over seven decades now.
  • With the explosion of available information, more than ever it’s time to get serious about accuracy, about knowing which sources can be trusted. Fortunately, there are emerging techniques that might help us to measure media accuracy cheaply, and then increase it.
  • ...7 more annotations...
  • We could continuously sample a news source’s output to produce ongoing accuracy estimates, and build social software to help the audience report and filter errors. Meticulously applied, this approach would give a measure of the accuracy of each information source, and a measure of the efficiency of their corrections process (currently only about 3% of all errors are corrected.)
  • Real world reporting isn’t always clearly “right” or “wrong,” so it will often be hard to decide whether something is an error or not. But we’re not going for ultimate Truth here,  just a general way of measuring some important aspect of the idea we call “accuracy.” In practice it’s important that the error counting method is simple, clear and repeatable, so that you can compare error rates of different times and sources.
  • Subjective errors, though by definition involving judgment, should not be dismissed as merely differences in opinion. Sources found such errors to be about as common as factual errors and often more egregious [as rated by the sources.] But subjective errors are a very complex category
  • One of the major problems with previous news accuracy metrics is the effort and time required to produce them. In short, existing accuracy measurement methods are expensive and slow. I’ve been wondering if we can do better, and a simple idea comes to mind: sampling. The core idea is this: news sources could take an ongoing random sample of their output and check it for accuracy — a fact check spot check
  • Standard statistical theory tells us what the error on that estimate will be for any given number of samples (If I’ve got this right, the relevant formula is standard error of a population proportion estimate without replacement.) At a sample rate of a few stories per day, daily estimates of error rate won’t be worth much. But weekly and monthly aggregates will start to produce useful accuracy estimates
  • the first step would be admitting how inaccurate journalism has historically been. Then we have to come up with standardized accuracy evaluation procedures, in pursuit of metrics that capture enough of what we mean by “true” to be worth optimizing. Meanwhile, we can ramp up the efficiency of our online corrections processes until we find as many useful, legitimate errors as possible with as little staff time as possible. It might also be possible do data mining on types of errors and types of stories to figure out if there are patterns in how an organization fails to get facts right.
  • I’d love to live in a world where I could compare the accuracy of information sources, where errors got found and fixed with crowd-sourced ease, and where news organizations weren’t shy about telling me what they did and did not know. Basic factual accuracy is far from the only measure of good journalism, but perhaps it’s an improvement over the current sad state of affairs
  •  
    Professional journalism is supposed to be "factual," "accurate," or just plain true. Is it? Has news accuracy been getting better or worse in the last decade? How does it vary between news organizations, and how do other information sources rate? Is professional journalism more or less accurate than everything else on the internet? These all seem like important questions, so I've been poking around, trying to figure out what we know and don't know about the accuracy of our news sources. Meanwhile, the online news corrections process continues to evolve, which gives us hope that the news will become more accurate in the future.

Google's in-house philosopher: Technologists need a "moral operating system" | VentureBeat - 0 views

  • technology-makers aren’t supposed to think about the morality of their products — they just build stuff and let other people worry about the ethics. But Horowitz pointed to the Manhattan Project, where physicists developed the nuclear bomb, as an obvious example where technologists should have thought carefully about the moral dimensions of their work. To put it another way, he argued that technology makers should be thinking as much about their “moral operating system” as their mobile operating system.
  • most of the evil in the world comes not from bad intentions, but rather from “not thinking.”

  • try to articulate how they decided what was right and wrong. “That’s the first step towards taking responsibility towards what we should do with all of our power,” Horowitz said, later adding, “We have so much power today. It is up to us to figure out what to do.”
  •  
    To illustrate how ethics are getting short-shrift in the tech world, Horowitz asked attendees whether they prefer the iPhone or Android. (When the majority voted for the iPhone, he joked that they were "suckers" who just chose the prettier device.) Then he asked whether it was a good idea to take data from an audience member's phone in order to provide various (and mostly beneficial) services, or whether he should be left alone, and the majority of audience voted to leave him alone. Finally, Horowitz wanted to know whether audience members would use the ideas proposed by John Stuart Mill or by Immanuel Kant to make that decision. Not surprisingly, barely anyone knew what he was talking about. "That's a terrifying result," Horowitz said. "We have stronger opinions about our handheld devices than about the moral framework we should use to guide our decisions."

When Science Trumps Policy: The Triumph of Insite « British Columbia « Canada... - 0 views

  • As skeptics we obviously want to see science based medicine and effective methods to improve public health. What this means is that, we skeptics, want to see medicine like vaccines promoted instead of homeopathy; but, we also want to see science based policy as well. What Insite has proven is that the harm reduction policy is working, in fact, working better than the “war on drugs” policy that the Conservative government has been supporting. Since the evidence is pointing to harm reduction being a more effective method of controlling the harmful effects of drug addiction in society, it should follow that harm reduction as a policy gain the support of our government and health care providers.
  • what was really distressing was that the Harper Government wasn’t just arguing against the evidence (saying for instance that it was either wrong or misguided) but actually arguing in spite of the evidence. What they were saying was that, yes, harm reduction appears to be working…but that’s irrelevant because that isn’t the policy we want to use.

Bodyshock - Age 8 and Wanting a Sex Change - 0 views

  • In America, children under 16 can be prescribed hormone 'blockers' to prevent the onset of puberty, with a view to then follow with hormone treatment to become their new gender. This film follows the American experience.
  • Using incorrect gender terms in such program as Bodyshock feels to me like almost mocking the whole idea of it. It seems disrespectful to those who decided to tell their stories, and to all others who have been born in bodies which do not reflect their actual gender
  • Bodyshock SHOULD be using the correct terms for thes children - Josie and Kyla should be refurred to as she and her, not he and his. Chris should be reffured to as he. Getting the gender terms wrong on a program about sex changes only reinforces the publics perceptions that it is okay to refure to transsexual people by the gender they were born as, and it's not.
  •  
    I think this is in a way related to biopower and how biotechnology has influenced our ethical stance on previously impossible/ unconceivable situations. I wonder what we may think about children under going sex change at such a young age. How can the children be so sure is definitely one of the first questions that demands answer.

Not Evil Just Wrong - The explosive new documentary exposing the dangers of global warm... - 0 views

  •  
    Something I received in my email - from American Family Association, an extreme conservative Christian network. The new documentary is basically a response to Al Gore's "An Inconvenient Truth", to (counter-)claim that the global warming "Industry" is causing alarmism and tax increases. From what I see, it's a highly capitalist-driven film. The online premiere will be on 18th Oct, 8pm est. Not directly related. But still interesting I guess. =)

flaneurose: The KK Chemo Misdosage Incident - 0 views

  • Labelling the pump that dispenses in ml/hr in a different color from the pump that dispenses in ml/day would be an obvious remedy that would have addressed the KK incident. It's the common-sensical solution that anyone can think of.
  • Sometimes, design flaws like that really do occur because engineers can't see the wood for the trees.
  • But sometimes the team is aware of these issues and highlights them to management, but the manufacturer still proceeds as before. Why is that? Because in addition to design principles, one must be mindful that there are always business considerations at play as well. Manufacturing two (or more) separate designs for pumps incurs greater costs, eliminates the ability to standardize across pumps, increases holding inventory, and overall increases complexity of business and manufacturing processes, and decreases economies of scale. All this naturally reduces profitability.It's not just pumps. Even medicines are typically sold in identical-looking vials with identically colored vial caps, with only the text on the vial labels differentiating them in both drug type and concentration. You can imagine what kinds of accidents can potentially happen there.
  • ...2 more annotations...
  • Legally, the manufacturer has clearly labelled on the pump (in text) the appropriate dosing regime, or for a medicine vial, the type of drug and concentration. The manufacturer has hence fulfilled its duty. Therefore, if there are any mistakes in dosing, the liability for the error lies with the hospital and not the manufacturer of the product. The victim of such a dosing error can be said to be an "externalized cost"; the beneficiaries of the victim's suffering are the manufacturer, who enjoys greater profitability, the hospital, which enjoys greater cost-savings, and the public, who save on healthcare. Is it ethical of the manufacturer, to "pass on" liability to the hospital? To make it difficult (or at least not easy) for the hospital to administer the right dosage? Maybe the manufacturer is at fault, but IMHO, it's very hard to say.
  • When a chemo incident like the one that happened in KK occurs, there are cries of public remonstration, and the pendulum may swing the other way. Hospitals might make the decision to purchase more expensive and better designed pumps (that is, if they are available). Then years down the road, when a bureaucrat (or a management consultant) with an eye to trim costs looks through the hospital purchasing orders, they may make the suggestion that $XXX could be saved by buying the generic version of such-and-such a product, instead of the more expensive version. And they would not be wrong, just...myopic.Then the cycle starts again.Sometimes it's not only about human factors. It could be about policy, or human nature, or business fundamentals, or just the plain old, dysfunctional way the world works.

Facebook groups hijacked - 1 views

  • ACTIVISTS claimed on Tuesday to have seized control of nearly 300 Facebook community groups in a self-proclaimed effort to expose how vulnerable online reputations are to tampering.
  • CYI claimed its motives were pure and that the move was more of a 'take-over' than a computer hack of Facebook groups.

      Sure, the end/ purpose is good... but the means? Questionable. Yet, it may be the only way to get people to formally recognize a flaw that everyone is well (sub)conscious about but refuses to do anything.  Freedom of expression perhaps? We're back to the issue of what is right and what is wrong. 
  • 'Facebook Groups suffer from a major flaw,' said a message on the CYI blog. 'If an administrator of a group leaves, anyone can register as a new admin. So, in order to take control of a Facebook group, all you really have to do is a quick search on Google.' Once CYI accessed groups as administrators it had authority to change anything, including pictures, descriptions and settings.

Straits Times Forum explains why it heavily edited letter | The Online Citizen - 0 views

  • 1. You stated we wrongly replaced the statistic you cited with another from Ms Rachel Chang’s article on March 8 (“School system still the ‘best way to move up’). Your original letter “It is indeed heartwarming to learn that 90% of children from one-to-three-room flats do not make it to university.” Reasons we edited it: Factual error, sense. There were two problems with your sentence. First, it was contradictory and didn’t make sense.Your original sentence cannot mean what it says unless you were elated over the fact that nine in 10 children from less well-off homes failed to qualify for university. So we edited it for sense, i.e., underscoring a positive feeling (heartwarming) with a positive fact; rather than the self-penned irony of a positive feeling (heartwarming) backed by a negative fact (90% failure rate to university admission by less well off children). That was why we replaced the original statistic with the only one in Ms Chang’s March 8 report that matched your elation, that is, that 50 percent of less well off children found tertiary success.
  • (Visa: Firstly, I find it hard to believe that nobody in the Straits Times office understands the meaning of sarcasm. Secondly, there was NO FACTUAL ERROR. Allow me to present to you the statistics, direct from The Straits Times themselves: http://www.straitstimes.com/STI/STIMEDIA/pdf/20110308/a10.pdf )
  • Second, we replaced your original statistic because it did not exist in Ms Chang’s March 8 front-page report. Ms Chang quoted that statistic in a later article (“Poor kids need aspiration: March 18; paragraph 5), which appeared after your letter was published. (Visa: It did not exist? Pay careful attention to the URL: http://www.straitstimes.com/STI/STIMEDIA/pdf/20110308/a10.pdf . Look at the number. 20110308. 2011 03 08. 8th March 2011.)
  • ...7 more annotations...
  • 2. Your original letter “His (Education Minister Dr Ng) statement is backed up with the statistic that 50% of children from the bottom third of the socio-economic ladder score in the bottom third of the Primary School Leaving Examination. “ Reason we edited it: Factual error
  • “His statement is backed by the statistic that about 50 per cent of children from the bottom third of the socio-economic bracket score within the top two-thirds of their Primary School Leaving Examination cohort. (Para 3 of Ms Chang’s March 8 report). (Visa:  THIS IS NOT A FACTUAL ERROR. If 50% of a group score in the top two-thirds, then the remaining 50% of the group, by simple process of elimination, must score in the bottom third!)
  • You can assume that the stats are wrong, but you CANNOT CHANGE it and CONTINUE to use the contributor’s name! Where is your journalist moral, ethic, and basic human decency? Since it is YOUR meaning, and not the writer’s, don’t it mean that you ABUSE, FABRICATE, and LIE to the public that that was by Samuel?
  • Either you print a news column or delete the letter. At least have some basic courtesy to call and ASK the writer for changes. Even a kid knows that its basic human decency to ask. HOW come you, as a grown man, YAP KOON HONG, can’t?
  • “So we edited it for sense ……. That was why we replaced the original statistic with the only one in Ms Chang’s March 8 report that matched your elation ……” and “So, we needed to provide the context to the minister’s statement in order to retain the sense of your meaning.” These are extraordinary statements. My understanding is that editors edit for clarity and brevity. It is extraordinary and perhaps only in Singapore that editors also edit for “sense”.
  • 50% make it to university therefore the other 50% did not make it. This kind of reasoning only works in primary or secondary school maths. In the real world, academia and journalism, the above would be considered a logical fallacy. To explain why, one must consider the fact that not going to university is not the same as “not making it”. World class musicians, sports, volunteer work, oversease universities, travel, these are just a few of the reasons why we can’t just do a simple calculation when it comes to statistics. Bill Gates didn’t go to university, would we classify him as “not making it” Sarcasm has no place in journalism as it relies on visual and vocal indicators to interpret. I live in Washington, and if the above letter was sent to any newspaper it would be thrown out with all the other garbage faster than you could say freedom of speech. At least the editor in question here bothered to try his best to get the letter published.
  • “we felt your opinion deserved publication” Please, Yap Koon Hong, what you published was the very opposite of his opinion! As you yourself admitted, Samuel’s letter was ironic in nature, but you removed all traces of irony and changed the statistics to fabricate a sense of “elation” that Samuel did not mean to convey!

Skepticblog » Global Warming Skeptic Changes His Tune - by Doing the Science ... - 0 views

  • To the global warming deniers, Muller had been an important scientific figure with good credentials who had expressed doubt about the temperature data used to track the last few decades of global warming. Muller was influenced by Anthony Watts, a former TV weatherman (not a trained climate scientist) and blogger who has argued that the data set is mostly from large cities, where the “urban heat island” effect might bias the overall pool of worldwide temperature data. Climate scientists have pointed out that they have accounted for this possible effect already, but Watts and Muller were unconvinced. With $150,000 (25% of their funding) from the Koch brothers (the nation’s largest supporters of climate denial research), as well as the Getty Foundation (their wealth largely based on oil money) and other funding sources, Muller set out to reanalyze all the temperature data by setting up the Berkeley Earth Surface Temperature Project.
  • Although only 2% of the data were analyzed by last month, the Republican climate deniers in Congress called him to testify in their March 31 hearing to attack global warming science, expecting him to give them scientific data supporting their biases. To their dismay, Muller behaved like a real scientist and not an ideologue—he followed his data and told them the truth, not what they wanted to hear. Muller pointed out that his analysis of the data set almost exactly tracked what the National Oceanographic and Atmospheric Administration (NOAA), the Goddard Institute of Space Science (GISS), and the Hadley Climate Research Unit at the University of East Anglia in the UK had already published (see figure).
  • Muller testified before the House Committee that: The Berkeley Earth Surface Temperature project was created to make the best possible estimate of global temperature change using as complete a record of measurements as possible and by applying novel methods for the estimation and elimination of systematic biases. We see a global warming trend that is very similar to that previously reported by the other groups. The world temperature data has sufficient integrity to be used to determine global temperature trends. Despite potential biases in the data, methods of analysis can be used to reduce bias effects well enough to enable us to measure long-term Earth temperature changes. Data integrity is adequate. Based on our initial work at Berkeley Earth, I believe that some of the most worrisome biases are less of a problem than I had previously thought.
  • ...4 more annotations...
  • The right-wing ideologues were sorely disappointed, and reacted viciously in the political sphere by attacking their own scientist, but Muller’s scientific integrity overcame any biases he might have harbored at the beginning. He “called ‘em as he saw ‘em” and told truth to power.
  • it speaks well of the scientific process when a prominent skeptic like Muller does his job properly and admits that his original biases were wrong. As reported in the Los Angeles Times : Ken Caldeira, an atmospheric scientist at the Carnegie Institution for Science, which contributed some funding to the Berkeley effort, said Muller’s statement to Congress was “honorable” in recognizing that “previous temperature reconstructions basically got it right…. Willingness to revise views in the face of empirical data is the hallmark of the good scientific process.”
  • This is the essence of the scientific method at its best. There may be biases in our perceptions, and we may want to find data that fits our preconceptions about the world, but if science is done properly, we get a real answer, often one we did not expect or didn’t want to hear. That’s the true test of when science is giving us a reality check: when it tells us “an inconvenient truth”, something we do not like, but is inescapable if one follows the scientific method and analyzes the data honestly.
  • Sit down before fact as a little child, be prepared to give up every preconceived notion, follow humbly wherever and to whatever abysses nature leads, or you shall learn nothing.

Rationally Speaking: Ray Kurzweil and the Singularity: visionary genius or pseudoscient... - 0 views

  • I will focus on a single detailed essay he wrote entitled “Superintelligence and Singularity,” which was originally published as chapter 1 of his The Singularity is Near (Viking 2005), and has been reprinted in an otherwise insightful collection edited by Susan Schneider, Science Fiction and Philosophy.
  • Kurzweil begins by telling us that he gradually became aware of the coming Singularity, in a process that, somewhat peculiarly, he describes as a “progressive awakening” — a phrase with decidedly religious overtones. He defines the Singularity as “a future period during which the pace of technological change will be so rapid, its impact so deep, that human life will be irreversibly transformed.” Well, by that definition, we have been through several “singularities” already, as technology has often rapidly and irreversibly transformed our lives.
  • The major piece of evidence for Singularitarianism is what “I [Kurzweil] have called the law of accelerating returns (the inherent acceleration of the rate of evolution, with technological evolution as a continuation of biological evolution).”
  • ...9 more annotations...
  • the first obvious serious objection is that technological “evolution” is in no logical way a continuation of biological evolution — the word “evolution” here being applied with completely different meanings. And besides, there is no scientifically sensible way in which biological evolution has been accelerating over the several billion years of its operation on our planet. So much for scientific accuracy and logical consistency.
  • here is a bit that will give you an idea of why some people think of Singularitarianism as a secular religion: “The Singularity will allow us to transcend [the] limitations of our biological bodies and brains. We will gain power over our fates. Our mortality will be in our own hands. We will be able to live as long as we want.”
  • Fig. 2 of that essay shows a progression through (again, entirely arbitrary) six “epochs,” with the next one (#5) occurring when there will be a merger between technological and human intelligence (somehow, a good thing), and the last one (#6) labeled as nothing less than “the universe wakes up” — a nonsensical outcome further described as “patterns of matter and energy in the universe becom[ing] saturated with intelligence processes and knowledge.” This isn’t just science fiction, it is bad science fiction.
  • “a serious assessment of the history of technology reveals that technological change is exponential. Exponential growth is a feature of any evolutionary process.” First, it is highly questionable that one can even measure “technological change” on a coherent uniform scale. Yes, we can plot the rate of, say, increase in microprocessor speed, but that is but one aspect of “technological change.” As for the idea that any evolutionary process features exponential growth, I don’t know where Kurzweil got it, but it is simply wrong, for one thing because biological evolution does not have any such feature — as any student of Biology 101 ought to know.
  • Kurzweil’s ignorance of evolution is manifested again a bit later, when he claims — without argument, as usual — that “Evolution is a process of creating patterns of increasing order. ... It’s the evolution of patterns that constitutes the ultimate story of the world. ... Each stage or epoch uses the information-processing methods of the previous epoch to create the next.” I swear, I was fully expecting a scholarly reference to Deepak Chopra at the end of that sentence. Again, “evolution” is a highly heterogeneous term that picks completely different concepts, such as cosmic “evolution” (actually just change over time), biological evolution (which does have to do with the creation of order, but not in Kurzweil’s blatantly teleological sense), and technological “evolution” (which is certainly yet another type of beast altogether, since it requires intelligent design). And what on earth does it mean that each epoch uses the “methods” of the previous one to “create” the next one?
  • As we have seen, the whole idea is that human beings will merge with machines during the ongoing process of ever accelerating evolution, an event that will eventually lead to the universe awakening to itself, or something like that. Now here is the crucial question: how come this has not happened already?
  • To appreciate the power of this argument you may want to refresh your memory about the Fermi Paradox, a serious (though in that case, not a knockdown) argument against the possibility of extraterrestrial intelligent life. The story goes that physicist Enrico Fermi (the inventor of the first nuclear reactor) was having lunch with some colleagues, back in 1950. His companions were waxing poetic about the possibility, indeed the high likelihood, that the galaxy is teeming with intelligent life forms. To which Fermi asked something along the lines of: “Well, where are they, then?”
  • The idea is that even under very pessimistic (i.e., very un-Kurzweil like) expectations about how quickly an intelligent civilization would spread across the galaxy (without even violating the speed of light limit!), and given the mind boggling length of time the galaxy has already existed, it becomes difficult (though, again, not impossible) to explain why we haven’t seen the darn aliens yet.
  • Now, translate that to Kurzweil’s much more optimistic predictions about the Singularity (which allegedly will occur around 2045, conveniently just a bit after Kurzweil’s expected demise, given that he is 63 at the time of this writing). Considering that there is no particular reason to think that planet earth, or the human species, has to be the one destined to trigger the big event, why is it that the universe hasn’t already “awakened” as a result of a Singularity occurring somewhere else at some other time?

The disappearing Yale-NUS article « The Mind Game - 0 views

  • I saw: “Comparing Yale in NUS and Cornell in Qatar“. Sounded quite interesting since I did read a bit about this Cornell in Qatar thing — uhh, in case I wanted to go somewhere where I could meet some oil tycoon’s daughter. So I clicked on the link and got:
  • Truth be told, I wasn’t thatttt interested — until it was taken down and hidden. I had to get my hands on those forbidden fruits! There was this other article that compared USP and YNC to show that there wasn’t much real difference in substance — only in surface packaging. And EVEN THEN, that five page of criticism wasn’t removed. So if this one got removed, it must be bleeding bleeding nasty. I had to see it. I just had to see it
  • I figured the most asshole thing I could do would be to reproduce the entire article here. But the crux of the article is essentially this: According to Cornell University’s own site, “Cornell is the first American university ever to offer its M.D. degree outside the United States.” The degree of involvement of Cornell in its Qatar campus differs markedly in two aspects. Firstly, the same degree is awarded to students from both campuses. Secondly, the Qatar campus is featured both on cornell.edu/visiting/qatar and on qatar-weill.cornell.edu — both sites hosted by Cornell University. As of the time of writing, we know that YNC degrees will be awarded by NUS, and the only website featuring YNC is hosted by NUS (ync.nus.edu.sg).

  • Three questions: 1. How Yale will the Yale-NUS thing be? 2. Why does Yale seem so much more reserved and passive, as compared to Cornell in Qatar? 3. Above all — Why did the article disappear suddenly? I can’t quite grasp the implications of this article — unless there was a really gross factual error. Normally, mistakes are just edited out later on anyway — unless there is something wrong with the core of the article. ….Of course, it could have just been a technical failure.

In books and countless speeches and television appearances, he has argued that poor countries are poor because they are hot, infertile, malaria-infested, and often landlocked; these factors, however, make it hard for them to be productive without an initial large investment to help them deal with such endemic problems. But they cannot pay for the investments precisely because they are poor -- they are in what economists call a "poverty trap." Until something is done about these problems, neither free markets nor democracy will do very much for them.
  • But then there are others, equally vocal, who believe that all of Sachs's answers are wrong. William Easterly, who battles Sachs from New York University at the other end of Manhattan, has become one of the most influential aid critics in his books, The Elusive Quest for Growth and The White Man's Burden. Dambisa Moyo, an economist who worked at Goldman Sachs and the World Bank, has joined her voice to Easterly's with her recent book, Dead Aid. Both argue that aid does more bad than good. It prevents people from searching for their own solutions, while corrupting and undermining local institutions and creating a self-perpetuating lobby of aid agencies.
  • The best bet for poor countries, they argue, is to rely on one simple idea: When markets are free and the incentives are right, people can find ways to solve their problems. They do not need handouts from foreigners or their own governments.
  • According to Easterly, there is no such thing as a poverty trap.
  • To find out whether there are in fact poverty traps, and, if so, where they are and how to help the poor get out of them, we need to better understand the concrete problems they face. Some aid programs help more than others, but which ones? Finding out required us to step out of the office and look more carefully at the world. In 2003, we founded what became the Abdul Latif Jameel Poverty Action Lab, or J-PAL. A key part of our mission is to research by using randomized control trials -- similar to experiments used in medicine to test the effectiveness of a drug -- to understand what works and what doesn't in the real-world fight against poverty. In practical terms, that meant we'd have to start understanding how the poor really live their lives.
  • Take, for example, Pak Solhin, who lives in a small village in West Java, Indonesia. He once explained to us exactly how a poverty trap worked. His parents used to have a bit of land, but they also had 13 children and had to build so many houses for each of them and their families that there was no land left for cultivation. Pak Solhin had been working as a casual agricultural worker, which paid up to 10,000 rupiah per day (about $2) for work in the fields. A recent hike in fertilizer and fuel prices, however, had forced farmers to economize. The local farmers decided not to cut wages, Pak Solhin told us, but to stop hiring workers instead. As a result, in the two months before we met him in 2008, he had not found a single day of agricultural labor. He was too weak for the most physical work, too inexperienced for more skilled labor, and, at 40, too old to be an apprentice. No one would hire him.
  • Pak Solhin, his wife, and their three children took drastic steps to survive. His wife left for Jakarta, some 80 miles away, where she found a job as a maid. But she did not earn enough to feed the children. The oldest son, a good student, dropped out of school at 12 and started as an apprentice on a construction site. The two younger children were sent to live with their grandparents. Pak Solhin himself survived on the roughly 9 pounds of subsidized rice he got every week from the government and on fish he caught at a nearby lake. His brother fed him once in a while. In the week before we last spoke with him, he had eaten two meals a day for four days, and just one for the other three.
  • Pak Solhin appeared to be out of options, and he clearly attributed his problem to a lack of food. As he saw it, farmers weren't interested in hiring him because they feared they couldn't pay him enough to avoid starvation; and if he was starving, he would be useless in the field. What he described was the classic nutrition-based poverty trap, as it is known in the academic world. The idea is simple: The human body needs a certain number of calories just to survive. So when someone is very poor, all the food he or she can afford is barely enough to allow for going through the motions of living and earning the meager income used to buy that food. But as people get richer, they can buy more food and that extra food goes into building strength, allowing people to produce much more than they need to eat merely to stay alive. This creates a link between income today and income tomorrow: The very poor earn less than they need to be able to do significant work, but those who have enough to eat can work even more. There's the poverty trap: The poor get poorer, and the rich get richer and eat even better, and get stronger and even richer, and the gap keeps increasing.
  • But though Pak Solhin's explanation of how someone might get trapped in starvation was perfectly logical, there was something vaguely troubling about his narrative. We met him not in war-infested Sudan or in a flooded area of Bangladesh, but in a village in prosperous Java, where, even after the increase in food prices in 2007 and 2008, there was clearly plenty of food available and a basic meal did not cost much. He was still eating enough to survive; why wouldn't someone be willing to offer him the extra bit of nutrition that would make him productive in return for a full day's work? More generally, although a hunger-based poverty trap is certainly a logical possibility, is it really relevant for most poor people today? What's the best way, if any, for the world to help?

Evolutionary analysis shows languages obey few ordering rules - 0 views

  • The authors of the new paper point out just how hard it is to study languages. We're aware of over 7,000 of them, and they vary significantly in complexity. There are a number of large language families that are likely derived from a single root, but a large number of languages don't slot easily into one of the major groups. Against that backdrop, even a set of simple structural decisions—does the noun or verb come first? where does the preposition go?—become dizzyingly complex, with different patterns apparent even within a single language tree.
  • Linguists, however, have been attempting to find order within the chaos. Noam Chomsky helped establish the Generative school of thought, which suggests that there must be some constraints to this madness, some rules that help make a language easier for children to pick up, and hence more likely to persist. Others have approached this issue via a statistical approach (the authors credit those inspired by Joseph Greenberg for this), looking for word-order rules that consistently correlate across language families. This approach has identified a handful of what may be language universals, but our uncertainty about language relationships can make it challenging to know when some of these are correlations are simply derived from a common inheritance.
  • For anyone with a biology background, having traits shared through common inheritance should ring a bell. Evolutionary biologists have long been able to build family trees of related species, called phylogenetic trees. By figuring out what species have the most traits in common and grouping them together, it's possible to identify when certain features have evolved in the past. In recent years, the increase in computing power and DNA sequences to align has led to some very sophisticated phylogenetic software, which can analyze every possible tree and perform a Bayesian statistical analysis to figure out which trees are most likely to represent reality. By treating language features like subject-verb order as a trait, the authors were able to perform this sort of analysis on four different language families: 79 Indo-European languages, 130 Austronesian languages, 66 Bantu languages, and 26 Uto-Aztecan languages. Although we don't have a complete roster of the languages in those families, they include over 2,400 languages that have been evolving for a minimum of 4,000 years.

  • The results are bad news for universalists: "most observed functional dependencies between traits are lineage-specific rather than universal tendencies," according to the authors. The authors were able to identify 19 strong correlations between word order traits, but none of these appeared in all four families; only one of them appeared in more than two. Fifteen of them only occur in a single family. Specific predictions based on the Greenberg approach to linguistics also failed to hold up under the phylogenetic analysis. "Systematic linkages of traits are likely to be the rare exception rather than the rule," the authors conclude.
  • If universal features can't account for what we observe, what can? Common descent. "Cultural evolution is the primary factor that determines linguistic structure, with the current state of a linguistic system shaping and constraining future states."
  • it still leaves a lot of areas open for linguists to argue about. And the study did not build an exhaustive tree of any of the language families, in part because we probably don't have enough information to classify all of them at this point.
  • Still, it's hard to imagine any further details could overturn the gist of things, given how badly features failed to correlate across language families. And the work might be well received in some communities, since it provides an invitation to ask a fascinating question: given that there aren't obvious word order patterns across languages, how does the human brain do so well at learning the rules that are a peculiarity to any one of them?
  •  
    young children can easily learn to master more than one language in an astonishingly short period of time. This has led a number of linguists, most notably Noam Chomsky, to suggest that there might be language universals, common features of all languages that the human brain is attuned to, making learning easier; others have looked for statistical correlations between languages. Now, a team of cognitive scientists has teamed up with an evolutionary biologist to perform a phylogenetic analysis of language families, and the results suggest that when it comes to the way languages order key sentence components, there are no rules.

The Black Swan of Cairo | Foreign Affairs - 0 views

  • It is both misguided and dangerous to push unobserved risks further into the statistical tails of the probability distribution of outcomes and allow these high-impact, low-probability "tail risks" to disappear from policymakers' fields of observation.
  • Such environments eventually experience massive blowups, catching everyone off-guard and undoing years of stability or, in some cases, ending up far worse than they were in their initial volatile state. Indeed, the longer it takes for the blowup to occur, the worse the resulting harm in both economic and political systems.
  • Seeking to restrict variability seems to be good policy (who does not prefer stability to chaos?), so it is with very good intentions that policymakers unwittingly increase the risk of major blowups. And it is the same misperception of the properties of natural systems that led to both the economic crisis of 2007-8 and the current turmoil in the Arab world. The policy implications are identical: to make systems robust, all risks must be visible and out in the open -- fluctuat nec mergitur (it fluctuates but does not sink) goes the Latin saying.

  • Just as a robust economic system is one that encourages early failures (the concepts of "fail small" and "fail fast"), the U.S. government should stop supporting dictatorial regimes for the sake of pseudostability and instead allow political noise to rise to the surface. Making an economy robust in the face of business swings requires allowing risk to be visible; the same is true in politics.
  • Both the recent financial crisis and the current political crisis in the Middle East are grounded in the rise of complexity, interdependence, and unpredictability. Policymakers in the United Kingdom and the United States have long promoted policies aimed at eliminating fluctuation -- no more booms and busts in the economy, no more "Iranian surprises" in foreign policy. These policies have almost always produced undesirable outcomes. For example, the U.S. banking system became very fragile following a succession of progressively larger bailouts and government interventions, particularly after the 1983 rescue of major banks (ironically, by the same Reagan administration that trumpeted free markets). In the United States, promoting these bad policies has been a bipartisan effort throughout. Republicans have been good at fragilizing large corporations through bailouts, and Democrats have been good at fragilizing the government. At the same time, the financial system as a whole exhibited little volatility; it kept getting weaker while providing policymakers with the illusion of stability, illustrated most notably when Ben Bernanke, who was then a member of the Board of Governors of the U.S. Federal Reserve, declared the era of "the great moderation" in 2004.
  • Washington stabilized the market with bailouts and by allowing certain companies to grow "too big to fail." Because policymakers believed it was better to do something than to do nothing, they felt obligated to heal the economy rather than wait and see if it healed on its own.
  • The foreign policy equivalent is to support the incumbent no matter what. And just as banks took wild risks thanks to Greenspan's implicit insurance policy, client governments such as Hosni Mubarak's in Egypt for years engaged in overt plunder thanks to similarly reliable U.S. support.
  • Those who seek to prevent volatility on the grounds that any and all bumps in the road must be avoided paradoxically increase the probability that a tail risk will cause a major explosion.
  • In the realm of economics, price controls are designed to constrain volatility on the grounds that stable prices are a good thing. But although these controls might work in some rare situations, the long-term effect of any such system is an eventual and extremely costly blowup whose cleanup costs can far exceed the benefits accrued. The risks of a dictatorship, no matter how seemingly stable, are no different, in the long run, from those of an artificially controlled price.
  • Such attempts to institutionally engineer the world come in two types: those that conform to the world as it is and those that attempt to reform the world. The nature of humans, quite reasonably, is to intervene in an effort to alter their world and the outcomes it produces. But government interventions are laden with unintended -- and unforeseen -- consequences, particularly in complex systems, so humans must work with nature by tolerating systems that absorb human imperfections rather than seek to change them.
  • What is needed is a system that can prevent the harm done to citizens by the dishonesty of business elites; the limited competence of forecasters, economists, and statisticians; and the imperfections of regulation, not one that aims to eliminate these flaws. Humans must try to resist the illusion of control: just as foreign policy should be intelligence-proof (it should minimize its reliance on the competence of information-gathering organizations and the predictions of "experts" in what are inherently unpredictable domains), the economy should be regulator-proof, given that some regulations simply make the system itself more fragile. Due to the complexity of markets, intricate regulations simply serve to generate fees for lawyers and profits for sophisticated derivatives traders who can build complicated financial products that skirt those regulations.
  • The life of a turkey before Thanksgiving is illustrative: the turkey is fed for 1,000 days and every day seems to confirm that the farmer cares for it -- until the last day, when confidence is maximal. The "turkey problem" occurs when a naive analysis of stability is derived from the absence of past variations. Likewise, confidence in stability was maximal at the onset of the financial crisis in 2007.
  • The turkey problem for humans is the result of mistaking one environment for another. Humans simultaneously inhabit two systems: the linear and the complex. The linear domain is characterized by its predictability and the low degree of interaction among its components, which allows the use of mathematical methods that make forecasts reliable. In complex systems, there is an absence of visible causal links between the elements, masking a high degree of interdependence and extremely low predictability. Nonlinear elements are also present, such as those commonly known, and generally misunderstood, as "tipping points." Imagine someone who keeps adding sand to a sand pile without any visible consequence, until suddenly the entire pile crumbles. It would be foolish to blame the collapse on the last grain of sand rather than the structure of the pile, but that is what people do consistently, and that is the policy error.
  • Engineering, architecture, astronomy, most of physics, and much of common science are linear domains. The complex domain is the realm of the social world, epidemics, and economics. Crucially, the linear domain delivers mild variations without large shocks, whereas the complex domain delivers massive jumps and gaps. Complex systems are misunderstood, mostly because humans' sophistication, obtained over the history of human knowledge in the linear domain, does not transfer properly to the complex domain. Humans can predict a solar eclipse and the trajectory of a space vessel, but not the stock market or Egyptian political events. All man-made complex systems have commonalities and even universalities. Sadly, deceptive calm (followed by Black Swan surprises) seems to be one of those properties.
  • The system is responsible, not the components. But after the financial crisis of 2007-8, many people thought that predicting the subprime meltdown would have helped. It would not have, since it was a symptom of the crisis, not its underlying cause. Likewise, Obama's blaming "bad intelligence" for his administration's failure to predict the crisis in Egypt is symptomatic of both the misunderstanding of complex systems and the bad policies involved.
  • Obama's mistake illustrates the illusion of local causal chains -- that is, confusing catalysts for causes and assuming that one can know which catalyst will produce which effect. The final episode of the upheaval in Egypt was unpredictable for all observers, especially those involved. As such, blaming the CIA is as foolish as funding it to forecast such events. Governments are wasting billions of dollars on attempting to predict events that are produced by interdependent systems and are therefore not statistically understandable at the individual level.
  • Political and economic "tail events" are unpredictable, and their probabilities are not scientifically measurable. No matter how many dollars are spent on research, predicting revolutions is not the same as counting cards; humans will never be able to turn politics into the tractable randomness of blackjack.
  • Most explanations being offered for the current turmoil in the Middle East follow the "catalysts as causes" confusion. The riots in Tunisia and Egypt were initially attributed to rising commodity prices, not to stifling and unpopular dictatorships. But Bahrain and Libya are countries with high gdps that can afford to import grain and other commodities. Again, the focus is wrong even if the logic is comforting. It is the system and its fragility, not events, that must be studied -- what physicists call "percolation theory," in which the properties of the terrain are studied rather than those of a single element of the terrain.
  • When dealing with a system that is inherently unpredictable, what should be done? Differentiating between two types of countries is useful. In the first, changes in government do not lead to meaningful differences in political outcomes (since political tensions are out in the open). In the second type, changes in government lead to both drastic and deeply unpredictable changes.
  • Humans fear randomness -- a healthy ancestral trait inherited from a different environment. Whereas in the past, which was a more linear world, this trait enhanced fitness and increased chances of survival, it can have the reverse effect in today's complex world, making volatility take the shape of nasty Black Swans hiding behind deceptive periods of "great moderation." This is not to say that any and all volatility should be embraced. Insurance should not be banned, for example.
  • But alongside the "catalysts as causes" confusion sit two mental biases: the illusion of control and the action bias (the illusion that doing something is always better than doing nothing). This leads to the desire to impose man-made solutions
  • Variation is information. When there is no variation, there is no information. This explains the CIA's failure to predict the Egyptian revolution and, a generation before, the Iranian Revolution -- in both cases, the revolutionaries themselves did not have a clear idea of their relative strength with respect to the regime they were hoping to topple. So rather than subsidize and praise as a "force for stability" every tin-pot potentate on the planet, the U.S. government should encourage countries to let information flow upward through the transparency that comes with political agitation. It should not fear fluctuations per se, since allowing them to be in the open, as Italy and Lebanon both show in different ways, creates the stability of small jumps.
  • As Seneca wrote in De clementia, "Repeated punishment, while it crushes the hatred of a few, stirs the hatred of all . . . just as trees that have been trimmed throw out again countless branches." The imposition of peace through repeated punishment lies at the heart of many seemingly intractable conflicts, including the Israeli-Palestinian stalemate. Furthermore, dealing with seemingly reliable high-level officials rather than the people themselves prevents any peace treaty signed from being robust. The Romans were wise enough to know that only a free man under Roman law could be trusted to engage in a contract; by extension, only a free people can be trusted to abide by a treaty. Treaties that are negotiated with the consent of a broad swath of the populations on both sides of a conflict tend to survive. Just as no central bank is powerful enough to dictate stability, no superpower can be powerful enough to guarantee solid peace alone.
  • As Jean-Jacques Rousseau put it, "A little bit of agitation gives motivation to the soul, and what really makes the species prosper is not peace so much as freedom." With freedom comes some unpredictable fluctuation. This is one of life's packages: there is no freedom without noise -- and no stability without volatility.∂

brianwhelan.net - Is Johann Hari a copy-pasting churnalist? - 0 views

  • many hacks lift quotes and thats not a crime but Hari appears to be passing off copy-pasted text from Levy’s writings in Haaretz and interviews with other hacks as an exclusive interview
  • The quote is sewn together with a string of other ideas Levy may or may not have shared with Hari but at no point does Hari indicate the quotes are taken from elsewhere. While Hari has questions to answer over the quotes he claims were given directly to him he also seems to be freely creating mash-up quotes out of disparate statements levy has made over the years. Not the practice of an award winning hack.
  • Hari has issued a reply that fails to explain why quotes are passed off as having been said directly to him; When interviewing a writer for a 6000-word profile, accurately quoting their writing is not “plagiarism” or “cut & paste journalism” Perhaps he would do better to heed his own words from August 2010; You don’t have a choice about being wrong sometimes: mistakes will be your life-long companion. But you do have a choice about whether to approach your error in terror so you suppress, ignore and repeat it – or to make it your honest, open ally in trying to get to the truth.
  •  
    Orwell Prize winning hack Johann Hari has some explaining to do. After reading a recent blog post detailing how he seems to have plagiarised large parts of his interview with Antonio Negri I thought I'd have a closer look at his work.

Johann Hari denies accusations of plagiarism | Media | guardian.co.uk - 0 views

  • "It's clearly not plagiarism or churnalism – but was it an error in another way? Yes. I now see it was wrong, and I wouldn't do it again. I'm grateful to the people who pointed out this error of judgment."
  • when contacted by the Guardian, Levy said he was not unhappy: "I stand behind everything that was published in the interview, which was an accurate representation of my thoughts and words."
  • Hari's interview read: "With a shake of the head, he says: 'We had now two wars, the flotilla – it doesn't seem that Israel has learned any lesson, and it doesn't seem that Israel is paying any price. The Israelis don't pay any price for the injustice of the occupation, so the occupation will never end. It will not end a moment before Israelis understand the connection between the occupation and the price they will be forced to pay. They will never shake it off on their own initiative.'"In July 2007, Levy wrote something very similar in a column for Haaretz: "The Israelis don't pay any price for the injustice of the occupation, so the occupation will never end. It will not end a moment before the Israelis understand the connection between the occupation and the price they will be forced to pay. They will never shake it off on their own initiative, and why should they?"
