  • [1110.5376] A Quan­ti­ta­tive Test of Pop­u­la­tion Genet­ics Using Spatio-​​Genetic Pat­terns in Bac­te­r­ial Colonies

    “It is widely accepted that pop­u­la­tion genet­ics the­ory is the cor­ner­stone of evo­lu­tion­ary analy­ses. Empir­i­cal tests of the the­ory, how­ever, are chal­leng­ing because of the com­plex rela­tion­ships between space, dis­per­sal, and evo­lu­tion. Crit­i­cally, we lack quan­ti­ta­tive val­i­da­tion of the spa­tial mod­els of pop­u­la­tion genet­ics. Here we com­bine ana­lyt­ics, on and off-​​lattice sim­u­la­tions, and exper­i­ments with bac­te­ria to per­form quan­ti­ta­tive tests of the the­ory. We study two bac­te­r­ial species, the gut microbe Escherichia coli and the oppor­tunis­tic pathogen Pseudomonas aerug­i­nosa, and show that spatio-​​genetic pat­terns in colony biofilms of both species are accu­rately described by an exten­sion of the one-​​dimensional stepping-​​stone model. We use one empir­i­cal mea­sure, genetic diver­sity at the colony periph­ery, to para­me­ter­ize our mod­els and show that we can then accu­rately pre­dict another key vari­able: the degree of short-​​range cell migra­tion along an edge. More­over, the model allows us to esti­mate other key para­me­ters includ­ing effec­tive pop­u­la­tion size (den­sity) at the expan­sion fron­tier. While our exper­i­men­tal sys­tem is a sim­pli­fi­ca­tion of nat­ural micro­bial com­mu­nity, we argue it is a proof of prin­ci­ple that the spa­tial mod­els of pop­u­la­tion genet­ics can quan­ti­ta­tively cap­ture organ­is­mal evolution.”

  • The Per­for­ma­tiv­ity of Net­works — Kieran Healy

    “The “per­for­ma­tiv­ity the­sis” is the claim that parts of con­tem­po­rary eco­nom­ics and finance, when car­ried out into the world by pro­fes­sion­als and pop­u­lar­iz­ers, refor­mat and reor­ga­nize the phe­nom­ena they pur­port to describe, in ways that bring the world into line with the­ory. Prac­ti­cal tech­nolo­gies, cal­cu­la­tive devices and portable algo­rithms give actors tools to imple­ment par­tic­u­lar mod­els of action. I argue that social net­work analy­sis is per­for­ma­tive in the same sense as the cases stud­ied in this lit­er­a­ture. Social net­work analy­sis and finance the­ory are sim­i­lar in key aspects of their devel­op­ment and effects. For the case of eco­nom­ics, evi­dence for weaker ver­sions of the per­for­ma­tiv­ity the­sis in quite good, and the strong for­mu­la­tion is cir­cum­stan­tially sup­ported. Net­work the­ory eas­ily meets the evi­den­tial thresh­old for the weaker ver­sions; I offer empir­i­cal exam­ples that sup­port the strong (or “Bar­ne­sian”) for­mu­la­tion. Whether these par­al­lels are a mark in favor of the the­sis or a strike against it is an open ques­tion. I argue that the social net­work tech­nolo­gies and mod­els now being “per­formed” build out sys­tems of gen­er­al­ized reci­procity, con­nec­tiv­ity, and commons-​​based pro­duc­tion. This is in con­trast both to an ear­lier net­work imagery that empha­sized self-​​interest and entre­pre­neur­ial exploita­tion of struc­tural oppor­tu­ni­ties, and to the model of action typ­i­cally con­sid­ered to be per­formed by eco­nomic technologies.”

    “Gulli­bil­ity is the prin­ci­pal cause of bub­bles. Investors and the gen­eral pub­lic get snared by a “beau­ti­ful illu­sion” and throw cau­tion to the wind. Attempts to iden­tify and con­trol bub­bles are com­pli­cated by the fact that the author­i­ties who might nat­u­rally be expected to take action have often (espe­cially in recent years) been among the most gullible, and were cheer­lead­ers for the exu­ber­ant behav­ior. Hence what is needed is an objec­tive mea­sure of gullibility.”

    “So what? Above a cer­tain count, do the num­bers even mat­ter? Well, yes. The dif­fer­ence between the two esti­mates is large enough to change the way we look at the war. The new esti­mate sug­gests that more men died as a result of the Civil War than from all other Amer­i­can wars com­bined. Approx­i­mately 1 in 10 white men of mil­i­tary age in 1860 died from the con­flict, a sub­stan­tial increase from the 1 in 13 implied by the tra­di­tional esti­mate. The death toll is also one of our most impor­tant mea­sures of the war’s social and eco­nomic costs. A higher death toll, for exam­ple, implies that more women were wid­owed and more chil­dren were orphaned as a result of the war than has long been sus­pected. In other words, the war touched more lives and com­mu­ni­ties more deeply than we thought, and thus shaped the course of the ensu­ing decades of Amer­i­can his­tory in ways we have not yet fully grasped. True, the war was ter­ri­ble in either case. But just how ter­ri­ble, and just how exten­sive its con­se­quences, can only be known when we have a bet­ter count of the Civil War dead.”

    ‘While Adam Smith may be known as the philoso­pher who first pro­moted the idea that “greed is good,” his ear­lier work sug­gests we are not con­demned to exploit oth­ers for the ben­e­fit of a few. In his book The The­ory of Moral Sen­ti­ments, writ­ten in 1759, Smith pro­posed that sym­pa­thy for the plight of those who suf­fer is an inher­ent part of human nature. “When we see one man oppressed or injured by another,” he wrote, “the sym­pa­thy which we feel with the dis­tress of the suf­ferer seems to serve only to ani­mate our fellow-​​feeling with his resent­ment against the offender.” With the cur­rent occu­pa­tion of Wall Street and the inter­na­tional con­dem­na­tion of an eco­nomic model that would take advan­tage of those most in need, we are wit­ness­ing Smith’s pre­dic­tion in action. It is only when the real­ity of people’s suf­fer­ing is hid­den that greed is allowed to dic­tate pol­icy. While our cur­rent sys­tem has cho­sen the greed of the few over the needs of the many, the intel­lec­tual founder of mod­ern cap­i­tal­ism sug­gests it doesn’t need to be this way. “When we think of the anguish of the suf­fer­ers, we take part with them more earnestly against their oppressors.”’

  • Guyot’s spec­i­man sheet | The Collation

    “So who was respon­si­ble and when is it from? Since the sheet is nei­ther signed nor dated, we can only make this asser­tion thanks to the sleuthing done by ear­lier schol­ars, most impor­tantly by John Drey­fus for his col­lec­tion of type spec­i­men fac­sim­i­les, and the source of much of the infor­ma­tion I give here.1 This sheet can be con­nected to its type caster thanks to the detailed records kept by the Dutch printer Christophe Plan­tin and the remark­able longevity of his press, now the home of the Plantin-​​Moretus Museum. Plantin’s 1575 inven­tory of fonts includes the dou­ble pica italic type­face shown on this sheet (it’s the largest size of the italic face, on the right-​​hand col­umn), with a note on the fac­ing page iden­ti­fy­ing it as “Ascen­don­ica Cur­sive de Guiot.” François Guyot was a type caster in Antwerp who worked from the 1540s until his death in 1570, and who was the main caster for Plan­tin from 1555 onwards; he also seems to have worked briefly for John Day in London.”

  • nth­most » Blog Archive » Why The Inter­state Bat­tery War­ranty is Worthless

    “We Can’t Afford to Just Be Con­sumers Any­more In the clas­si­cal model of eco­nom­ics, a self-​​interested con­sumer like Josh would read­ily accept Interstate’s offer, see­ing no down­side. But Josh is part of a new class of con­sumers who under­stand the idea of “vot­ing with your dol­lar”, and it goes well beyond which brand of toi­let paper you bring to the check­out line. There are sev­eral imme­di­ate down­sides to the “res­o­lu­tion” Inter­state brought to the table: Fire­stone would be rewarded for their ridicu­lous 2-​​hour-​​minimum pol­icy to change the bat­tery. Inter­state would con­tinue to be unable to enforce their war­ranty. The cus­tomer (Josh) would have no rea­son to believe he’d be able to get a new bat­tery in the future with­out all of the non­sense implied by the res­o­lu­tion — namely, pay­ing for the 2 hours of labor him­self and then secur­ing reim­burse­ment from Inter­state. Josh looked at the options and decided not to enable the ven­dors in their bul­ly­ing of Inter­state, and not to encour­age Inter­state to bend over for them. And he real­ized his time in chas­ing down his due was worth more than the value of the prod­uct in question.”

    “At this point, it’s eas­ier to under­stand why econ­o­mists feel so defen­sive about chal­lenges to the Myth of Barter, and why they keep telling the same old story even though most of them know it isn’t true. If what they are really describ­ing is not how we ‘nat­u­rally’ behave but rather how we are taught to behave by the market—well who, nowa­days, is doing most of the actual teach­ing? Pri­mar­ily, econ­o­mists. The ques­tion of barter cuts to the heart of not only what an econ­omy is—most econ­o­mists still insist that an econ­omy is essen­tially a vast barter sys­tem, with money a mere tool (a posi­tion all the more pecu­liar now that the major­ity of eco­nomic trans­ac­tions in the world have come to con­sist of play­ing around with money in one form or another) [10]—but also, the very sta­tus of eco­nom­ics: is it a sci­ence that describes of how humans actu­ally behave, or pre­scrip­tive, a way of inform­ing them how they should? (Remem­ber, sci­ences gen­er­ate hypoth­e­sis about the world that can be tested against the evi­dence and changed or aban­doned if they don’t prove to pre­dict what’s empir­i­cally there.) Or is eco­nom­ics instead a tech­nique of oper­at­ing within a world that econ­o­mists them­selves have largely cre­ated? Or is it, as it appears for so many of the Aus­tri­ans, a kind of faith, a revealed Truth embod­ied in the words of great prophets (such as Von Mises) who must, by def­i­n­i­tion be cor­rect, and whose the­o­ries must be defended what­ever empir­i­cal real­ity throws at them—even to the extent of gen­er­at­ing imag­i­nary unknown peri­ods of his­tory where some­thing like what was orig­i­nally described ‘must have’ taken place?”

    “In their recent book Eco­nomic Anthro­pol­ogy, Chris Hann and Keith Hart write about one of their main goals:  “We hope to per­suade econ­o­mists with real world con­cerns to take an inter­est in what anthro­pol­o­gists have dis­cov­ered about the human econ­omy, and in the kinds of the­o­ries we have advanced to under­stand it” (Hann and Hart 2011:9).  How­ever, they also make this point quite clear: “There is not much hope for dia­logue with those who define eco­nom­ics exclu­sively as the appli­ca­tion of an indi­vid­u­al­is­tic logic of util­ity max­i­miza­tion to all domains of social life” (Hann and Hart 2011:9).  Ulti­mately, they say, “The project of eco­nom­ics needs to be res­cued from the econ­o­mists” (Hann and Hart 2011:162).”
