Psychology World originally shared this post: The human brain’s connections turn out to be a an orderly 3D grid structure with no diagonals. 2D sheets of parallel fibers cross at right angles — ” like the warp and weft of a fabric.” The first pictures from the most powerful brain scanner of its kind reveal an “astonishingly simple architecture.” This diffusion spectrum image of a whole human brain came from the new Connectom scanner, part of the NIH’s Human Connectome Project.This video has NO audio.

THE STANDING OVATION PROBLEM “THE BASIC…

The Standing Ovation Problem “The basic SOP can be stated as: A brilliant economics lecture ends and the audience begins to applaud. The applause builds and tentatively, a few audience members may or may not decide to stand. Does a standing ovation ensue or does the enthusiasm fizzle? Inspired by the seminal work of Schelling (1978), the SOP possesses sucient structure to generate nontrivial dynamics without imposing too many a priori modeling constraints. Like Schelling’s work, it focuses on the macro-behavior that emerges from micro-motives, and relies on models that emphasize agents driven by simple behavioral algorithms placed in interesting spatial contexts. Though ostensibly simple, the social dynamics responsible for a standing ovation are complex. As the performance ends, each audience member must decide whether or not to stand. Of course, if the decision to stand is simply a personal choice based on the individual’s own assessment of the worth of the performance, the problem becomes trivial. However, people do not stand solely based upon their own impressions of the performance. A seated audience member surrounded by people standing might be enticed to stand, even if he hated the performance. This behavioral mimicry could be strategic (the agents wants to send the right signal to the lecturer), informational (maybe the lecture was better than he thought), or conformal (he stands so as to not feel awkward). Regardless of the source of these peer effects, they set the stage (so to speak) for interesting dynamic behavior.” Miller, John, and Scott E.

RESHARED POST FROM BETSY MCCALL

I wrote this in the comment of the original thread below. I have no idea if I’m right, but I thought I’m going to save it for posterity (vanity) anyway. For what it’s worth, nothing like this is mentioned in the linked article in Nature. __ If the biological analog of quantum theory is the theory of evolution, then the biological analog of the Higgs boson is the neural correlate of the meme. The theory of evolution is highly explanatory, and predicts a wide range of observed phenomena. It doesn’t give you a set of linear equations, but it does describe a set of complex dynamics that allows for a detailed study of the very mechanisms of life. Like the standard model, some of these mechanisms are well studied and understood. The biological equivalent of the electrons are the genes: the most familiar and well understood mechanisms predicted by the theory. At the moment, we understand electrons far better than we understand genes– that is, we can do more with them. But the last few decades have seen incredible advances in genetic engineering, and we are only becoming more confident in our grasp. The theory of evolution also has natural and obvious applications in the areas of psychology and sociology, but applying the theory in these areas is like walking through a minefield, and there are few places where we can do so with any confidence. The lack of confidence about the specifics, however, betrays a much deeper confidence in the generalities: the same biological models that explain the organization of other biological systems should likewise explain the organization of both brains and networks of brains. Both phenomena are pervasive biological phenomena, but we lack the mechanism, the “fundamental particle”, to unify their treatment with the genetic models we’ve been […]

Ciro Villa originally shared this post: …”The recently-launched Runmycode has thrown another bridge across these divides, a bridge that allows scientists and academics in the fields of economics and business to test the logic of an argument by testing the code that expresses it. A user can employ Runmycode for free to automatically create a website built around a given professional paper in between 15 and 45 minutes. The central feature of the resultant site is a cloud-based data simulator, developed in J2EE, that allows a user to test the paper’s assertions. This simulator allows readers, especially other scientists and those for whom the paper may prove the most useful, to test the arguments in the paper with their own data set.”… Runmycode lets scientists crowdsource code testing A new service removes a little more of the barrier between academics and the public by automatically producing a companion website for each paper researchers author.

THERE IS A FUNDAMENTAL LEVEL AT WHICH MARX…

There is a fundamental level at which Marx’s nightmare vision is right: capitalism, the market system, whatever you want to call it, is a product of humanity, but each and every one of us confronts it as an autonomous and deeply alien force. Its ends, to the limited and debatable extent that it can even be understood as having them, are simply inhuman. The ideology of the market tell us that we face not something inhuman but superhuman, tells us to embrace our inner zombie cyborg and lose ourselves in the dance. One doesn’t know whether to laugh or cry or run screaming. But, and this is I think something Marx did not sufficiently appreciate, human beings confront all the structures which emerge from our massed interactions in this way. A bureaucracy, or even a thoroughly democratic polity of which one is a citizen, can feel, can be, just as much of a cold monster as the market. We have no choice but to live among these alien powers which we create, and to try to direct them to human ends. It is beyond us, it is even beyond all of us, to find “a human measure, intelligible to all, chosen by all”, which says how everyone should go. What we can do is try to find the specific ways in which these powers we have conjured up are hurting us, and use them to check each other, or deflect them into better paths. http://cscs.umich.edu/~crshalizi/weblog/918.html In Soviet Union, Optimization Problem Solves You Attention conservation notice: Over 7800 words about optimal planning for a socialist economy and its intersection with computational complexity theory.

RESHARED POST FROM FLORIAN ROHRWECK

+Callum J Hackett commented: “Is it dickish of me to say that once the fund got to around, say, $100,000, people should have thought, “Maybe it’s time to turn my money to an actual charity”? Yes, those kids were awful (though I have to say that she didn’t look much like she cared given the gravity of some of the things they said), and yes it’s great that people have come out in support of her. But I think this is an example of people behaving disproportionately, and though we hear it happening all the time with bad things, it can happen with good things like this too. I think, as a crowd, the people who have donated have become carried away with indulgence in generosity, perhaps for the fuzzy feeling it gives them rather than her. I don’t think it’s rationally sustainable to make a random woman rich because she was treated like crap by children when there’s so much agony elsewhere in the world that even half of the money this woman will receive could help with enormously.” https://plus.google.com/u/0/110603832885954401865/posts/WmdDv8sL9Xw I left the following response in his thread: I think you are right that this is a disproportionate response. The problem is that there is no infrastructure to ensure that the good will generated on the internet is used productively and effectively, or that its response are in proportion to the crimes that instigated it. Such infrastructure doesn’t yet exist; +Jonathan Zittrain keynote at ROFLCon is in some sense a call for that infrastructure. The paradigm case of such disproportionate response was the Kony 2012 meme, the fastest spreading meme in history and (consequently) the most radically disproportionate ratio of virality to actual accomplishment we’ve ever seen.

‘A PERFECT AND BEAUTIFUL MACHINE’: WHAT…

‘A Perfect and Beautiful Machine’: What Darwin’s Theory of Evolution Reveals About Artificial Intelligence by Dan Dennett “What Darwin and Turing had both discovered, in their different ways, was the existence of competence without comprehension. This inverted the deeply plausible assumption that comprehension is in fact the source of all advanced competence. Why, after all, do we insist on sending our children to school, and why do we frown on the old-fashioned methods of rote learning? We expect our children’s growing competence to flow from their growing comprehension. The motto of modern education might be: “Comprehend in order to be competent.” For us members of H. sapiens, this is almost always the right way to look at, and strive for, competence. I suspect that this much-loved principle of education is one of the primary motivators of skepticism about both evolution and its cousin in Turing’s world, artificial intelligence. The very idea that mindless mechanicity can generate human-level — or divine level! — competence strikes many as philistine, repugnant, an insult to our minds, and the mind of God.” More: http://www.theatlantic.com/technology/archive/2012/06/a-perfect-and-beautiful-machine-what-darwins-theory-of-evolution-reveals-about-artificial-intelligence/258829/ via +Neil Smith

THE ATTENTION ECONOMY PRIMER THIS PRIMER…

The Attention Economy Primer This primer is designed to introduce newbies to some basic concepts and readings on the attention economy. Far from being comprehensive, this guide focuses on recent contributions to this great conversation, sorted into rough categories for ease of use. There is a lot of material here, some of which is quite difficult, and not all of it is explicitly connected. However, I hope that taken together this guide sketches a picture of the social, political, and economic stakes of perhaps the most radical restructuring of social organization that humanity has ever dared to undertake, and of the science that has made it possible. More: http://digitalinterface.blogspot.com/2012/06/attention-economy-primer.html #attentioneconomy #bigdata #complexity #science #internet #digitalvalues #digitalculture ______________________________ +Gideon Rosenblatt asked me to put together a reading list on the attention economy last week. It took me a while, but I pulled together around 20 important contributions to the discussion, sorted it by category, and wrote a brief introductory essay to hold it together. Some of it may be familiar, but hopefully enough is new and interesting to encourage further exploration. This is a lot of material, probably more than a summer’s worth. Sorry Gideon! Still, this is a developing story, and I hope to continue to update and argument this primer as more people start to contribute to the discussion. Suggestions, criticisms, and contributions are always welcome. If you appreciate this work, please participate!
