Freakonomics » Concierge Service for the Masses - 0 views

  • Agent Anything is part matching and part auction; it sets up “agents” with “missions,” with the price for each task set by the buyer. The missions range from delivering food to assembling IKEA furniture to doing manual labor like data entry. The other night, my roommate had some Ben & Jerry’s delivered at his right price. He even gave a tip.

Lessig on science, copyright and the moral case for open access - Boing Boing - 0 views

  • Larry Lessig's talk at CERN on the way that copyright interacts with science publishing is a stirring call-to-arms to free up scientific discovery and inquiry. While artists debate the questions of exclusive rights, income, creativity and copyright, scientists operate in a different tradition. Since the Enlightenment, wide publication and review of scientific material has been the cornerstone of good scientific practice.
  • Whereas copyright tends to focus on protecting artists' ability to make money from their work, scientists don't use similar incentives. And yet, her work is often kept within the gates of the ivory tower, reserved for those whose universities or institutions have purchased access, often at high costs. And for science in the age of the internet, which wants ideas to spread as widely as possible to encourage more creativity and development, this isn't just bad: it's immoral.

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.∂

Our local Animation industry | the kent ridge common - 0 views

  • While many industrial veterans here put the blame solely on the “bo chap” attitudes of the students, I wish to point out the fact that those industrial veterans in the animation industry are just too afraid to admit that it was the fault of the tertiary education systems. It is true that while some students have an attitude problem, the lecturers in the polytechnics and universities have their fair share of the blame too. I also wish to speak up for students who have the passion for the industry but they are not shown the right path. Otherwise how do you explain that it took my mentor 2 years and only half the price of the poly fees to teach me all that I needed to know to find a job in the CG industry?

The Great Beyond: Lab sabotage deemed research misconduct (with exclusive surveillance ... - 0 views

  • Yesterday, the Office of Research Integrity (ORI), part of the US Department of Health and Human Services, issued a finding of research misconduct for Vipul Bhrigu, a former postdoctoral fellow at the University of Michigan, debarring him for three years from involvement in US federally funded research and from serving as an advisor to the US Public Health Service. The federal register carried the note today. Bhrigu, now in India, was caught on videotape sabotaging the experiments of a graduate student in his lab at the univeristy last year. And today, Nature releases exclusive surveillance tapes, obtained through the Freedom of Information Act in Michigan.
  • Video: This video, obtained by Nature via the Freedom of Information Act, shows Vipul Bhrigu carrying a spray bottle full of ethanol into the refrigerator where Heather Ames had stored her cell culture media and contaminating her reagents.

Climate Researchers Urged To Use 'Plain Language' - Science News - redOrbit - 0 views

  • James White of the University of Colorado at Boulder told fellow researchers to use plain language when describing their research to a general audience. Focusing on the reports technical details could obscure the basic science. To put it bluntly, “if you put more greenhouse gases in the atmosphere, it will get warmer,” he said. US climate scientist Robert Corell said it was pertinent to try to reach out to all members of society to spread awareness of Arctic melt and the impact it has on the whole world. “Stop speaking in code. Rather than 'anthropogenic,' you could say 'human caused,” Corell said at the conference of nearly 400 scientists.

Greening the screen » Scienceline - 0 views

  • But not all documentaries take such a novel approach. Randy Olson, a marine biologist-turned-filmmaker at the University of Southern California, is a harsh critic of what he sees as a very literal-minded, information-heavy approach within the environmental film genre. Well-intentioned environmental documentary filmmakers are just “making their same, boring, linear, one-dimensional explorations of issues,” said Olson. “The public’s not buying it.”
  • The problem may run deeper than audience tallies — after all, An Inconvenient Truth currently ranks as the sixth-highest grossing documentary in the United States. However, a 2010 study by social psychologist Jessica Nolan found that while the film increased viewers’ concern about global warming, that concern didn’t translate into any substantial action a month later.
  • To move a larger audience to action, Olson advocates a shift from the literal-minded world of documentary into the imaginative world of narrative.
  • ...4 more annotations...
  • One organization using this approach is the Science and Entertainment Exchange, a program of the National Academy of Sciences. The Exchange puts writers, producers, and directors in touch with scientists and engineers who can answer specific questions or just brainstorm ideas. For example, writers for the TV show Fringe changed their original plot point of mind control through hypnosis to magnetic manipulation of brain waves after speaking with a neuroscientist at the Salk Institute for Biological Studies in La Jolla, California.
  • Hollywood, Health and Society (HHS), a program of the Centers for Disease Control and Prevention, takes a similar approach by providing free resources to the entertainment industry. HHS connects writers and producers — from prime time dramas like Law and Order and House to daytime soap operas – with experts who can provide accurate health information for their scripts.
  • HHS Director Sandra Buffington admits that environmental issues, especially climate change, pose particular challenges for communicators because at first glance, they are not as immediately relevant as personal health issues. However, she believes that by focusing on real, human stories — climate refugees displaced by rising water levels, farmers unable to grow food because of drought, children sick because of outbreaks of malaria — the issues of the planet will crystallize into something tangible. All scientists need to do is provide the information, and the professional creative storytellers will do the rest, she says.
  • Olson also takes a cue from television. He points to the rise of reality TV shows as a clear indication of where the general public interest lies. If environmentalists want to capture that interest, Olson thinks they need to start experimenting with these innovative types of unscripted forms. “That’s where the cutting edge exists,” he said.
  •  
    For environmentalists trying to use entertainment to shape broad public attitudes and behaviors, nothing could be more important than understanding how to reach these hard-to-get people. Something that will speak to them, something that will change their minds, and most importantly, something that will incite them to action. A documentary might not be that something.

A Data Divide? Data "Haves" and "Have Nots" and Open (Government) Data « Gurs... - 0 views

  • Researchers have extensively explored the range of social, economic, geographical and other barriers which underlie and to a considerable degree “explain” (cause) the Digital Divide.  My own contribution has been to argue that “access is not enough”, it is whether opportunities and pre-conditions are in place for the “effective use” of the technology particularly for those at the grassroots.
  • The idea of a possible parallel “Data Divide” between those who have access and the opportunity to make effective use of data and particularly “open data” and those who do not, began to occur to me.  I was attending several planning/recruitment events for the Open Data “movement” here in Vancouver and the socio-demographics and some of the underlying political assumptions seemed to be somewhat at odds with the expressed advocacy position of “data for all”.
  • Thus the “open data” which was being argued for would not likely be accessible and usable to the groups and individuals with which Community Informatics has largely been concerned – the grassroots, the poor and marginalized, indigenous people, rural people and slum dwellers in Less Developed countries. It was/is hard to see, given the explanations, provided to date how these folks could use this data in any effective way to help them in responding to the opportunities for advance and social betterment which open data advocates have been indicating as the outcome of their efforts.

  • many involved in “open data” saw their interests and activities being confined to making data ‘legally” and “technically” accessible — what happened to it after that was somebody else’s responsibility.
  • while the Digital Divide deals with, for the most part “infrastructure” issues, the Data Divide is concerned with “content” issues.
  • where a Digital Divide might exist for example, as a result of geographical or policy considerations and thus have uniform effects on all those on the wrong side of the “divide” whatever their socio-demographic situation; a Data Divide and particularly one of the most significant current components of the Open Data movement i.e. OGD, would have particularly damaging negative effects and result in particularly significant lost opportunities for the most vulnerable groups and individuals in society and globally. (I’ve discussed some examples here at length in a previous blogpost.)
  • Data Divide thus would be the gap between those who have access to and are able to use Open (Government) Data and those who are not so enabled.
  • 1. infrastructure—being on the wrong side of the “Digital Divide” and thus not having access to the basic infrastructure supporting the availability of OGD. 2. devices—OGD that is not universally accessible and device independent (that only runs on I-Phones for example) 3. software—“accessible” OGD that requires specialized technical software/training to become “usable” 4. content—OGD not designed for use by those with handicaps, non-English speakers, those with low levels of functional literacy for example 5.  interpretation/sense-making—OGD that is only accessible for use through a technical intermediary and/or is useful only if “interpreted” by a professional intermediary 6. advocacy—whether the OGD is in a form and context that is supportive for use in advocacy (or other purposes) on behalf of marginalized and other groups and individuals 7. governance—whether the OGD process includes representation from the broad public in its overall policy development and governance (not just lawyers, techies and public servants).

Genetic Sequencing Will Have to Wait: Links Between Genes and Behavior Still Largely Un... - 0 views

  • A recent article in The New York Times reported that over 100 studies show a relationship between genes and criminality but that the environment plays a key role in the effects of this relationship: “Kevin Beaver, an associate professor at Florida State University’s College of Criminology and Criminal Justice, said genetics may account for, say, half of a person’s aggressive behavior, but that 50 percent comprises hundreds or thousands of genes that express themselves differently depending on the environment. He has tried to measure which circumstances — having delinquent friends, living in a disadvantaged neighborhood — influence whether a predisposition to violence surfaces. After studying twins and siblings, he came up with an astonishing result: In boys not exposed to the risk factors, genetics played no role in any of their violent behavior. The positive environment had prevented the genetic switches — to use Mr. Pinker’s word — that affect aggression from being turned on. In boys with eight or more risk factors, however, genes explained 80 percent of their violence. Their switches had been flipped.”
  • “This idea that if something is genetic it’s deterministic is a misconception that we have to get over because saying that genes are involved in depression does not necessarily mean that someone who has certain genetic variants is doomed to become depressed, it just means that under certain circumstances, he or she may have to do certain things to help alleviate it, but it’s not unchangeable. You can change your brain, you can change your brain in many different ways and genetics is just one of many of these ways.”
  • In fact, environment plays the same crucial role for criminality as it does for obesity and depression. In an interview I did for a story in The Michigan Daily on depression research, Dr. Margit Burmeister, a professor of human genetics and a researcher in the Molecular and Biological Neuroscience Institute at the University of Michigan, explained the dangers the public oversimplifying the link between genetics and depression:

Search Engines Change How Memory Works | Wired Science | Wired.com - 0 views

  • study co-author and Columbia University psychologist Elizabeth Sparrow said it’s just another form of so-called transactive memory, exhibited by people working in groups in which facts and expertise are distributed.
  • A direct comparison of transactive learning by individuals in groups and on computers has not been performed. It would be interesting to see how they stack up, said Sparrow. It would also be interesting to further compare how transactive and internal memory function. They could affect other thought processes: For example, someone relying on internalized memory may review and synthesize other memories during recall. One small but intriguing effect in the new study involved students who were less able to identify subtly manipulated facts, such as a changed name or date, when drawing on memories they thought were saved online.
  •  
    Thanks to search engines, most simple facts don't need to be remembered. They can be accessed with a few keystrokes, plucked from ubiquitous server-stored external memory - and that may be changing how our own memories are maintained. A study of 46 college students found lower rates of recall on newly-learned facts when students thought those facts were saved on a computer for later recovery. If you think a fact is conveniently available online, then, you may be less apt to learn it.

Hans Rosling: It's Easier to Reach Fame Than Impact « Kimo Quaintance - 0 views

  • What are the most important lessons you’ve learned about using social media for teaching and outreach? It is easier to reach fame than impact. If it’s so personal, you run the risk of standing in the way of your content.
  • What’s the single most important piece of advice you would give to someone just starting out in university-level teaching? Pick the subjects and courses that really interest you rather than those that are predicted to give you nice job and salary, but study what you study very hard and go deeper and broader than what is required.
  • Are there any special skills we should be teaching our students in the digital age that are different than those we would have taught them in the past? Critical thinking, reasoning and a quest for sources of all information. And when in doubt, rely on Wikipedia. It is amazingly good, especially if you carefully read the history of the text of interest.

Are the Open Data Warriors Fighting for Robin Hood or the Sheriff?: Some Refl... - 0 views

  • The ideal that these nerdy revolutionaries are pursuing is not, as with previous generations—justice, freedom, democracy—rather it is “openness” as in Open Data, Open Information, Open Government. Precisely what is meant by “openness” is never (at least certainly not in the context of this conference) really defined in a form that an outsider could grapple with (and perhaps critique). 
  • the “open data/open government” movement begins from a profoundly political perspective that government is largely ineffective and inefficient (and possibly corrupt) and that it hides that ineffectiveness and inefficiency (and possible corruption) from public scrutiny through lack of transparency in its operations and particularly in denying to the public access to information (data) about its operations.
  • further that this access once available would give citizens the means to hold bureaucrats (and their political masters) accountable for their actions. In doing so it would give these self-same citizens a platform on which to undertake (or at least collaborate with) these bureaucrats in certain key and significant activities—planning, analyzing, budgeting that sort of thing. Moreover through the implementation of processes of crowdsourcing this would also provide the bureaucrats with the overwhelming benefits of having access to and input from the knowledge and wisdom of the broader interested public.

  • t’s the taxpayer’s money and they have the right to participate in overseeing how it is spent. Having “open” access to government’s data/information gives citizens the tools to exercise that right. And (it is argued), solutions are available for putting into the hands of these citizens the means/technical tools for sifting and sorting and making critical analyses of government activities if only the key could be turned and government data was “accessible” (“open”).
  • A lot of the conference took place in specialized workshops where the technical details on how to link various sets of this newly available data together with other sets, how to structure this data so that it could serve various purposes and perhaps most importantly how to design the architecture and ontology (ultimately the management policies and procedures) of the data itself within government so that it is “born open” rather than only liberated after the fact with this latter process making the usefulness of the data in the larger world of open and universally accessible data much much greater.
  • it matters very much who the (anticipated) user is since what is being put in place are the frameworks for the data environment  of the future and these will include for the most part some assumptions about who the ultimate user is or will be and whether or not a new “data divide” will emerge written more deeply into the fabric of the Information Society than even the earlier “digital (access) divide”.
