RESHARED POST FROM GIDEON ROSENBLATT

The hybrid ideal Today it is clear that the independence of social value and commercial revenue creation is a myth. In reality, the vectors of social value and commercial revenue creation can reinforce and undermine each other. The social consequences of the recent financial crisis demonstrated with great clarity the danger of “negative externalities”—social costs resulting from corporate profit-seeking activities. But in some cases, “positive externalities” may also exist. It is this possibility that integrated hybrid models seek to exploit. When we talk to entrepreneurs and students about hybrid organizations, a common theme that emerges is what we call the “hybrid ideal.” This hypothetical organization is fully integrated—everything it does produces both social value and commercial revenue.4 This vision has at least two powerful features. In the hybrid ideal, managers do not face a choice between mission and profit, because these aims are integrated in the same strategy. More important, the integration of social and commercial value creation enables a virtuous cycle of profit and reinvestment in the social mission that builds large-scale solutions to social problems. http://www.ssireview.org/articles/entry/in_search_of_the_hybrid_ideal via +Gregory Esau _______________ It is wonderful to see so many people waking up simultaneously to the same basic unified frameworks. People are catching on to it from so many diverse perspective it is very humbling. The overlap and diversity of perspectives is interesting for many reasons. “The Hybrid Ideal”, for instance, is a very clearly transhumanist value, but I imagine that the number of people involved in producing or sharing this content that explicitly recognize it as such is vanishingly small. I personally get this content through the small-but-growing network of businessmen and entrepreneurship whose interesting organizational strategies have been filling my stream. This amuses me somewhat, because I’m an anarchist looking to seize the means of production, yet somehow we’ve […]

RESHARED POST FROM MATT UEBEL

Matt Uebel originally shared this post: “How is it possible to have any informed democratic debate over a policy about which the U.S. media relentlessly propagandizes this way? If drone strikes kill nobody other than “militants,” then very few people will even think about opposing them (and that’s independent of the fact that the word “militant” is a wildly ambiguous term — militant about what? — though it is clearly designed (when combined with “Pakistan”) to evoke images of those who attacked the World Trade Center). Debate-suppression is not just the effect but the intent of this propaganda: like all propaganda, it is designed to deceive the citizenry in order to compel acquiescence to government conduct.” Deliberate media propaganda The media now knows that “militant” is a term of official propaganda, yet still use it for America’s drone victims

RESHARED POST FROM PBS NEWSHOUR

vis +James Wood. Pasting his comment below: “An effect of the constant advances in technology is a complete restructuring of the way we think about the division of labor and citizens’ roles in a future society. As our lives become ever more digitalized, we realize many real concerns–namely the fear that a handful of extremely wealthy and extremely powerful individuals will take over the world, leaving the rest of us to fight over the few “real” jobs remaining. However, in an #attentioneconomy , such disparity can not exist. First of all, the Internet in future forms can reach the point that it itself functions as an economy–one of attention and attenders. Imagine that machines have evolved to the point at which manual human labor is truly obsolete; they become in a way our “digital” infrastructure. then whatever frontier remains unconquered will become the platform for our human interaction (the Internet). This network will still be just as competitive as any free market system to date, only it will be wholly self-organized, meaning that the behavior of the network as a whole will be more or less equally influenced by each individual node. The main obstruction to this practically in the future is that in this vast digital infrastructure, you might ask, who controls that? Who owns it? Who makes sure it is functioning properly? If a few people do own it, then wouldn’t the very phenomenon we are trying to avoid still happen in an attention economy (other-organized network)? The answer is that no one owns the infrastructure (or anything). The infrastructure will become advanced enough that it becomes essentially self-improving, self-organizing, self-replicating, etc. The technology will become intelligent, or I daresay, alive (oooh). It will become integrated into our very consciousness–it will become us, or rather extensions of us. […]

RESHARED POST FROM XAVIER MARQUEZ

Cognitive Democracy “This points, we think, to a very clear constructive agenda. To exaggerate a little, it is to see how far the Internet enables modern democracies to make as much use of their citizens’ minds as did Ober’s Athens. We want to learn from existing online ventures in collective cognition and decision-making. We want to treat these ventures are, more or less, spontaneous experiments10, and compare the success and failures (including partial successes and failures) to learn about institutional mechanisms which work well at harnessing the cognitive diversity of large numbers of people who do not know each other well (or at all), and meet under conditions of relative equality, not hierarchy. If this succeeds, what we learn from this will provide the basis for experimenting with the re-design of democratic institutions themselves.” ______ This is absolutely wonderful. Via +Michael Chui Xavier Marquez originally shared this post: Cosma Shalizi and +Henry Farrell make an epistemic argument for democracy (vis a vis markets and hierarchies). I suspect at this level of generality the question is a bit too abstract – the more interesting questions remain below this level, concerning the scope of each mechanism and the mediation of conflicts at the edges between markets, participatory discussion fora, and hierarchies. Nevertheless, a very interesting piece. Cognitive Democracy But the economical advantages of commerce are surpassed in importance by those of its effects which are intellectual and moral.

+DILAN TORY AND +STEVEN WAGNER RAISE SOME…

+dilan tory and +Steven Wagner raise some interesting questions regarding the complaint in the linked article. Any thoughts from the stream? Quoting dilan’s question below. “Dan, I thought you might be interested in the legal/conceptual issues here. Steve wonders what you think about the following: What counts as a database/what does intent mean in this context? As for myself, I’m just wondering how often someone in France has to search for “Jew” after a name to cause google’s algorithmic whizgizmos to suggest it as a prompt. And I want to know whether French people do this more than, say, Germans or Americans-is French pop culture becoming obsessively anti-semitic? I can’t help but find this menacing–I’m in the middle of reading the postwar correspondance between Jaspers and Hannah Arendt…” _____ One interesting thing to consider is that Google already shapes your search results according to personalized metrics. In other words, if my communities are heavily involved and influential in, say, antisemetic circles, that would tend to raise the number of antisemetic results I’d get in a search. Presumably, this is what I’d want, given my online communities. Consequently, laws like this seem like ways of restricting which communities one might engage with. This might seem like an acceptable result when dealing with so-called “hate-based” communities, but of course when state institutions have this kind of authority it tends to over step its bounds. More generally, I think a lot of issues with online censorship are traditionally understood in terms of “free speech”, and so issues like this become difficult because it isn’t exactly clear what speech is getting suppressed when you silence autocomplete results. I’d personally suggest that +Google (as an artificially intelligent computing agent, not the corporation) is having its speech suppressed, but since I don’t think Google yet has […]

THE LOGIC OF DIVERSITY THE COMPLEXITY OF…

The Logic of Diversity The Complexity of a Controversial Concept By +Cosma Shalizi … The division of labor is, in part, an adaptation for handling complex problems, but only those which are complex in the straightforward sense of being very large. It relies on finding a way of decomposing the large problem into nearly-separate parts, so that it can be attacked through a strategy of divide-and-conquer, with different people specializing in conquering the various divisions. (This topic, and its relation to hierarchical structure, was explored by Herbert Simon in his classic Sciences of the Artificial.) Diversity, in the sense Page is talking about, is another way of adapting to complexity, and specifically to complex problems which are not decomposable into neat hierarchies. Put strategically, the idea is like this: Agents have only a limited capacity to represent, learn about, and predict their world, and so solve their problems. When the problem or environment is too complex for any one agent, then you should have many weak agents make partial, incomplete, overlapping representations. You’ll be better off by doing this, and then learning a way to combine them, than by trying to find a single, globally accurate representation, such as a single super-genius agent which can handle the problem all by itself. Collectively, the combined representations of the group of agents are equivalent to a single high-capacity representation. But nobody, individually, has anything like the complete picture; in fact, everybody’s individual picture is pretty much wrong, or at best drastically incomplete. Powerful, high-level capacities which emerge from the interplay of low-level components are a common feature of complex systems, but here as elsewhere, just having the components and letting them interact is not enough. The organization of the interactions is crucial. In the brain, for instance, this is the difference between […]

RESHARED POST FROM BRUNO GONÇALVES

+Bruno Gonçalves and his colleagues have put together attention-based models looking at Twitter activity in the run up to the #americanidol decisions. They were able to predict the winner with a pretty high degree of confidence using an extremely simplified model of the Twitter activity. They posted the model to the arXiv a few days ago, and then updated with results from the big vote yesterday. Their updated paper is linked below. This is both a validation and benchmarking case for quantifying and modeling the #attentioneconomy . They conclude: ” We have shown that the open source data available on the web can be used to make educated guesses on the outcome of societal events. Speci?cally, we have shown that extremely simple measures quantifying the popularity of the American Idol participants on Twitter strongly correlate with their performances in terms of votes. A post-event analysis shows that the less voted competitors can be identi?ed with reasonable accuracy (Table II) looking at the Twitter data collected during the airing of the show and in the immediately following hours.” Bruno Gonçalves originally shared this post: Beating the news using Social Media: the case study of American Idol. (arXiv:1205.4467v2 [physics.soc-ph] UPDATED) We present a contribution to the debate on the predictability of social events using big data analytics. We focus on the elimination of contestants in the American Idol TV shows as an example of a well defined electoral phenomenon that each week draws millions of votes in the USA. We provide evidence that Twitter activity during the time span defined by the TV show airing and the voting period following it, correlates with the contestants ranking and allows the anticipation of the voting outc…

THE 20TH CENTURY WAS THE PEAK OF THE INDUSTRIAL…

The 20th century was the peak of the Industrial Age, and it culminates with the invention of the Internet. The mythical structure is that of the Titans, warring and fighting and love-making in order to give birth to the Gods that ultimately overthrow them. Industrialization is about ordering; when humanity is the one so ordered the result is #alienation . In this fabulous interview, Postman delivers the 20th century’s worries about the Digital Age as clearly and humbly as one can. The potential for radical alienation is, he thinks, the stakes of this Faustian bargain. What everyone in the 20th century missed was that the Digital Revolution isn’t just a continuation of the ordering of the Industrial Age. Instead, the Digital Age is about organization. Understanding how order and organization differ is the conceptual basis for the paradigm shift, but you don’t need to understand the concepts to see it’s implications. This paradigm shift is precisely why the paradigmatic structures of the digital age are the communities that Postman worries might not exist in the Digital World. In fact, such communities thrive in abundance, largely because we’ve worked out the ways for being co-present and assembling digitally. In 1995 those communities were still distant and hard to reach, but today billions of us are there, and it works. Postman expected that technological change breeds only order, and thereby alienation, and so his worries here are entirely appropriate. In fact, technological change can also breed organization, and organization is holistic and presents only solutions to the alienation of the Industrial Age. Our deeply human sociality won out over the imposed alienation, and for this reason the Digital Age is reworking the fundamental organizational structure we’ve inherited from the age of industry.

RESHARED POST FROM JOHN BAEZ

John Baez originally shared this post: My last post showed a video of a ‘multi-scale Turing pattern’ which creates patterns that look biological. But it had perfect 3-fold symmetry artificially imposed on it, which is a bit of a cheat. Nature builds symmetrical patterns in some more subtle way – ‘imperfect’ but robust. So until we figure that out, I like this asymmetrical example better. W. Blut wrote: “It’s been more than two years since I came across his [Jonathan McCabe’s] multi-scale Turing pat­terns. They instantly intrigued me. And although I could recre­ate the gist of his images, I could never over­come the prac­ti­cal problems. In fact, the code proved haz­ardous to the elderly, infants and pregnant women. I thought my lack of numer­i­cal skill in tack­ling the huge equa­tions I ran into was the prob­lem. It was pon­der­ously slow and I suspected Jonathan had a secret lair packed with supercomputers.” “Turns out I was being silly. An almost inci­den­tal post on Flickr revealed that Jonathan has a paper on his cyclic sym­met­ric multi-scale Turing patt.., what the hell, on his McCabeisms. And it’s full of DTC lines (a rarely needed acronym for “damn that’s clever”). Seems I wasn’t bark­ing up the wrong tree, I was in the wrong for­est, on the wrong con­ti­nent, on the wrong planet… As if that wasn’t enough, Jason Rampe pro­vides a blog post with use­ful point­ers in imple­ment­ing Jonathan’s idea.

LIVE STREAMING AND GAMIFYING EDUCATION IN…

Live Streaming and Gamifying Education In addition to +Fraser Cain and +Pamela Gay‘s brilliant Astronomy Hangouts, one other vibrant community of streamers has heavily influenced my thinking about the medium: the Starcraft 2 streaming community. Although the community has significant presences across the internet (especially on Reddit and Twitter), the heart of the community is on the Team Liquid forums. If you aren’t familiar, hit up the link and let me introduce you to the community. At the time of my posting, there are 95 live streamers reaching an audience of roughly 16,000 viewers. This is near midnight on an average Wednesday; during major tournaments or other community events, audiences will easily clock in over 100,000 viewers. And the community is attracting advertising dollars in proportion to the attention it attracts. Starcraft is one of a number of games streamed regularly on services like Twitch.tv, which hosts streams to thousands of viewers daily. http://www.twitch.tv/directory But the Team Liquid forums cater to the SC2 community directly, and have generated quite a sophisticated culture and economy surrounding their gaming. http://www.teamliquid.net/video/streams/ At top of this list are a number of features streams. Some featured streams are highly produced tournaments; right now, the IGN Pro League is streaming their tournament, complete with casting and commentary, studio productions, and commercial sponsorship. This produced content is usually broadcast several times during the day. Other featured streams are professional Starcraft players live streaming their own online play. Individual streamers are also usually sponsored and run their own advertisements (either on screen logos during the game, or full screen commercials between games), and are paid in proportion to their viewership. Some pros, like Destiny, support themselves entirely through their streaming. http://www.reddit.com/r/IAmA/comments/g7q91/iam_destiny_i_quit_my_job_to_play_starcraft_2_for/ The really interesting thing for me, however, is the other live streams, the “long tail” of the […]

RESHARED POST FROM JOHN BAEZ

John Baez originally shared this post: How much a message tells you depends on what you were expecting. We can understand this very precisely using the concept of ‘relative information’. Today I’ll explain this and give an incredibly cool application to biology. Suppose a population of organisms has an evolutionarily stable state. Then as time passes, the information in this stable state relative to its current state always decreases! In short: the population keeps learning through natural selection, so it has less ‘left to learn’. (This is a theorem proved by +Marc Harper and others. Like all theorems, it has assumptions… and these assumptions don’t fit nicely into a G+ post. So please read the blog article before you argue.)

RESHARED POST FROM COLIN MACKAY

Objectification The following are philosopher Martha Nussbaum’s criteria for objectification, that is, the act of treating a person as an object: instrumentality: the treatment of a person as a tool for the objectifier’s purposes; denial of autonomy: the treatment of a person as lacking in autonomy and self-determination; inertness: the treatment of a person as lacking in agency, and perhaps also in activity; fungibility: the treatment of a person as interchangeable with other objects; violability: the treatment of a person as lacking in boundary-integrity; ownership: the treatment of a person as something that is owned by another (can be bought or sold); denial of subjectivity: the treatment of a person as something whose experiences and feelings (if any) need not be taken into account. To which Professor Rae Langton, MIT, adds the following: reduction to body: the treatment of a person as identified with their body, or body parts; reduction to appearance: the treatment of a person primarily in terms of how they look, or how they appear to the senses; silencing: the treatment of a person as if they are silent, lacking the capacity to speak.

RESHARED POST FROM CLIFF HARVEY

Cliff Harvey originally shared this post: Lawrence Lessig interviews Jack Abramoff about the US political system, institutional corruption, and strategies for reform. I knew this was going to be great immediately based on the participants. Lawrence Lessig studies political corruption at Harvard and has been advocating a proposal to soften the dependence of the political system on outside money (See: Rootstriking ), while Jack Abramoff is arguably one of the most effective (former) lobbyists in the business. He did hard time for some abuses, but as they make clear, the legal restrictions are so loose its almost hard to imagine the need to break them. I thought this conversation was extraordinarily fascinating, especially for some of the specific insights into the actual mechanisms of power used by this class of people – “that world” as Jack calls it – and also because this is exactly the kind of insight that needs to be accounted for in order to craft a smart strategy to reign in the corrosive dependence of politicians on private money that has denied them of any real autonomy. Jack seems pretty genuinely reflective, ashamed and serious about trying to help contain the damage done by people like himself. I think we’d be wise to hear what he has to say. The meta-organization seeking to address this key structural issue is called United Republic, which incorporates several smaller organizations. I’d definitely encourage giving them a look, and your email: http://unitedrepublic.org/

RESHARED POST FROM JON LAWHEAD

Jon Lawhead originally shared this post: I’ve had a paper about the foundations of mathematics in my head for a while now. I had a long conversation with a good friend who does quantum field theory today, and found him unexpectedly sympathetic to the view. Now I’m thinking seriously about writing it. This is partly scratch paper for recording my thoughts, and partially an RFC. If anyone out there has any thoughts about this, please chime in. I’ve always been sympathetic to a kind of formalism, and I think that the big objections that get raised to the formalist program aren’t necessarily fatal. The spirit of the program can (I think) be decoupled from Hilbert’s personal project of providing a complete and consistent foundation for arithmetic (which Godel torpedoed), and from the formulation that requires all of mathematics to computerized. The spirit of formalism just requires that mathematics be thought of as kind of symbol manipulation game in which we play around with constructed formal systems, deducing as many consequences as we can from a set of axioms. I think it’s possible to give a concrete version of formalism that satisfies this spirit, but which doesn’t run afoul of either the Turing or Godel-based objections. In particular, I’d like to target the “unreasonable effectiveness of mathematics” argument (which sort of parallels the “no miracles” argument in the philosophy of science. The quick and dirty version of that argument is that if mathematics isn’t “discovering” genuine truths about real objects in the world, it seems incredibly miraculous that so much of contemporary mathematics has turned out to be so useful for doing science. It seems to me that this is something like being astonished by the fact that so many words in the English language actually represent objects in the real […]

THE EULERIZER OUR GOAL IS TO REVEAL TEMPORAL…

The Eulerizer Our goal is to reveal temporal variations in videos that are difficult or impossible to see with the naked eye and display them in an indicative manner. Our method, which we call Eulerian Video Magnification, takes a standard video sequence as input, and applies spatial decomposition, followed by temporal filtering to the frames. The resulting signal is then amplified to reveal hidden information. Using our method, we are able to visualize the flow of blood as it fills the face and also to amplify and reveal small motions. Our technique can run in real time to show phenomena occurring at temporal frequencies selected by the user.

THE EULERIZER OUR POST FROM JOHN BAEZ

John Baez originally shared this post: Q: What’s negative information? A: I could tell you, but then you’d know even less… Just kidding. In 2005 Michal Horodecki, Jonathan Oppenheim and Andreas Winter wrote a nice paper on negative information. I find it a bit easier to think about entropy. Entropy is the information you’re missing about the precise details of a system. For example, if I have a coin under my hand and you can’t see which side it up, you’ll say it has an entropy of one bit. Suppose you have a big physical system B and some part of it, say A. In classical mechanics the entropy of B is always bigger than that of A: S(B) ? S(A) where S means ‘entropy’. In particular, if we know everything we can about B, we know all we can about A. In quantum mechanics this isn’t true, so S(B) – S(A) can be negative. For example, it’s possible to have an entangled pair of electrons with no entropy, where if we look at either one, it has an entropy of one bit: we don’t know if it’s spin is up or down. The paper by Horodecki, Oppenheim and Winter studied the implications of negative information for communication. There was a popularization here: Quantum information can be negative, Phys.org, 4 August 2005, http://phys.org/news5621.html but I understood less after reading it than before, so I decided to write this. Puzzle: why do physicists use S to stand for entropy?
