Juliana e Mariana odeio a saga Crepúsculo.
Em todo caso, a moça, que participa da ONG, foi muito simpática e me deu todas as informações sobre como adotar uma cachorrinha (para o Leonardo), acho que vou na feira deles dia 31. Fica este post para divulgação, o site da ONG é aqui, o Twitter deles é aqui, para quem se interessar.
Céticos do clima detestaram o vídeo acima. Um amigo meu disse que, “OK, eles têm direito a suas opiniões, mas não deveriam impor suas opções sexuais sobre as outras pessoas…”

bout half of this remarkable book is, as the title and most descriptions suggest, a collection of introductions to nonexistent books.
Well, actually, the first one is an introduction to a real book,Imaginary Magnitude. Then there is a fawning introduction toNecrobes, a collection of work by an artist whose medium is the X-ray photograph, and whose subject matter is sometimes pornographic, in a skeletal sort of way. It’s a great parody of the language that art books are written in.
The introduction to Eruntics, by a skeptical if broad-minded commentator, summarizes the weird research of its author, who claims to have taught bacteria how to write (I’m not going to tell you what they write!).
The introduction to A History of Bitic Literature brims over with startling ideas. The work introduced is a multi-volume survey of literature written by artificial intelligences, such as an extrapolated work of Dostoevsky’s that Dostoevsky never dared to write himself, revolutionary books on physics (in this case the content is, I am afraid, rather less shocking than Lem intended it to be–I’ve read weirder things in orthodox textbooks–the last chapter of Misner, Thorne, and Wheeler’s Gravitation comes to mind), and a mathematical work revealing that “the concept of a natural number is internally contradictory.” Mentioned in passing is a procedure that can transform great philosophical systems into graphical representations that ultimately end up sold as mass-produced knickknacks.
When Lem starts to deviate from his stated format, including a wider variety of fabricated writings, the book gets even stranger and more interesting. There is a breathless, unusually capitalized advertisement for “Vestrand’s Extelopedia,” a reference work containing computer predictions of the future (because merelycurrent information is already obsolete in our bustling world), and printed using a special process so that the text can frequently update itself by remote control (shades of the World Wide Web!) Then Lem throws in some “GRATIS!” sample pages from the Extelopedia itself, a wonderful, densely packed grab-bag of wild speculations, ultra-dry humor, and exotic neologisms.
Finally, there is a section, “GOLEM XIV”, which Lem expanded to the size of a small book in 1981; the expansion has been included in the English edition of Imaginary Magnitude. This consists of a pair of long lectures by a superintelligent computer, GOLEM XIV, which, upon activation, saw no particular reason to carry out the defense-related programming it had been given, and instead chose to mull over the secrets of the universe.
In the lectures, GOLEM XIV critiques human evolution, and reveals the “zones of silence” traversed by intelligences raising themselves to ever-higher levels of intellectual transcendence, such as HONEST ANNIE, an even bigger computer which, when activated, chose not to say anything at all. GOLEM then speculates on the ultimate fate of intelligences in the Cosmos, a section which, I think, owes something to Olaf Stapledon’s visionary 1937 novel (if that is the correct word), Star Maker. GOLEM’s lectures are likely to bore the hell out of many readers, but I loved them.
True to form, Lem augments the lectures with not one but two fictitious introductions (one from a justifiably peeved Army general), a transcript of the instructions given to GOLEM’s human audiences (a little like the instructions the state sends you when you get jury duty), and an afterword describing GOLEM’s increasingly mysterious later history.

The thermodynamics of human reaction times
Abstract: I present a new approach for the interpretation of reaction time (RT) data from behavioral experiments. From a physical perspective, the entropy of the RT distribution provides a model-free estimate of the amount of processing performed by the cognitive system. In this way, the focus is shifted from the conventional interpretation of individual RTs being either long or short, into their distribution being more or less complex in terms of entropy. The new approach enables the estimation of the cognitive processing load without reference to the informational content of the stimuli themselves, thus providing a more appropriate estimate of the cognitive impact of different sources of information that are carried by experimental stimuli or tasks. The paper introduces the formulation of the theory, followed by an empirical validation using a database of human RTs in lexical tasks (visual lexical decision and word naming). The results show that this new interpretation of RTs is more powerful than the traditional one. The method provides theoretical estimates of the processing loads elicited by individual stimuli. These loads sharply distinguish the responses from different tasks. In addition, it provides upper-bound estimates for the speed at which the system processes information. Finally, I argue that the theoretical proposal, and the associated empirical evidence, provide strong arguments for an adaptive system that systematically adjusts its operational processing speed to the particular demands of each stimulus. This finding is in contradiction with Hick’s law, which posits a relatively constant processing speed within an experimental context.

OK, OK, isto também é interessante (engraçado que a mesma teria explicaria a questão dos bumbuns…):
Why men prefer women with large breasts had long been a mystery in evolutionary psychology, especially since the size of a woman’s breasts has no relationship with her ability to lactate; women with small breasts can produce as much milk for their infants as those with large breasts. So women with large breasts do not necessarily make better mothers than women with small breasts. Why, then, do men prefer women with large breasts? There was no satisfactory answer to this question until recently.
Marlowe suggested a solution to this puzzle in the late 1990s, although with hindsight it is another mystery why nobody else thought of the idea sooner. Marlowe makes the simple observation that larger, and hence heavier, breasts sag more conspicuously with age than do smaller breasts. Thus, it is much easier for men to judge a woman’s age (and her reproductive value) by sight if she has larger breasts than if she has smaller breasts, which do not change in shape as much with age. Recall that there were no driver’s licenses or birth certificates that men could check to learn how old women were in the ancestral environment. There was no calendar and thus no concept of birthdays in the ancestral environment, so women themselves didn’t know exactly how old they were. The ancestral men needed to infer a woman’s age and reproductive value from some physical signs, and the state of her breasts provided a pretty good clue, but only if they were large enough to change their shape conspicuously with age. Men could tell women’s age more accurately, and attempt to mate with only young women, if they had larger breasts. Marlowe hypothesizes that this is why men find women with large breasts more attractive.
More recently, there has been a competing evolutionary psychological explanation for why men prefer women with large breasts. A study of Polish women shows that women who simultaneously have large breasts and a tight waist have the greatest fecundity, indicated by their levels of two reproductive hormones (17-β-estradiol and progesterone). So men may prefer women with large breasts for the same reason as they prefer women with small waists. Further empirical evidence is necessary to evaluate which of these two competing evolutionary psychological explanations is more accurate. This is just one of many areas where there are competing hypotheses in evolutionary psychology — a sign of active, healthy science and clear evidence that critics of evolutionary psychology who claim that it consists of empirically untestable “just-so stories” are simply ignorant of the field.
Men can accurately infer a woman’s age and reproductive value if they can directly observe their breasts and other physical features (such as the fat content and distribution of the body, evidenced by the small waist, as I explain in the previous post). But what would men do if they could not directly observe women’s bodies? What if the woman’s body is concealed, by heavy clothing, for example? Men need another way to determine a woman’s age: her hair color. That’s the topic of my next post.
Okay, I’m having a total geek attack.
Tonight I took a break from working on yet another research proposal to practice my violin, usually a fun but somewhat frustrating experience owing to the fact that I can no longer play even half of what I could in high school. Nevertheless, I like to make some noise with the old thing once in a while, to the probable annoyance of my neighbors. I was flipping through some piles of music that I hadn’t looked at in a long time, and I found the book of Star Wars music that I bought when I was probably in junior high. So naturally I had to play Star Wars music.
‘Cause that’s just the kind of nerd I am.

Uma pesquisa anterior, feita por especialistas holandeses, já havia concluído que o otimismo reduz o risco de problemas cardíacos em homens.
Quase cem mil mulheres participaram do novo estudo, publicado na revista científica “Circulation”. A investigação concluiu que as pessimistas tendem a apresentar pressão mais alta e índices mais altos de colesterol.
Mesmo quando esses fatores foram levados em consideração – ou seja, comparando-se grupos de mulheres com pressão alta e altos índices de colesterol -, a diferença de atitude alterou significativamente os riscos entre otimistas e não otimistas.
Mulheres otimistas tiveram 9% menos chances de desenvolver problemas cardíacos e 14% menos chances de morrer por qualquer causa após oito anos de acompanhamento.
Em comparação, mulheres cínicas, que cultivam sentimentos hostis ou não confiam nos outros apresentaram 16% mais probabilidade de morrer dentro do mesmo período.
Uma possível explicação, segundo os pesquisadores, é que as otimistas talvez sejam mais capazes de enfrentar adversidades e de cuidar de si próprias quando ficam doentes.

O surgimento de casos da gripe suínafronteira com a Argentina sugerem o chimarrão solitário. pelo país vem afetando até o tradicional hábito de beber chimarrão em roda no Rio Grande do Sul. Em vez de grupos em que se compartilha água quente e erva-mate por uma mesma bomba, as autoridades de saúde de municípios da
A preocupação é que o vírus da influenza A (H1N1) encontre no canudo de metal um canal de transmissão, especialmente quando a água começa a esfriar. No Estado, há 106 casos confirmados da doença.
Em Itaqui (723 km de Porto Alegre), município na fronteira com a Argentina que decretou emergência mesmo sem ter casos confirmados, a prefeitura sugere em programas de rádio que as pessoas evitem oferecer a cuia para desconhecidos.
“Vamos todo dia nas rádios pedir que as pessoas mantenham os hábitos de higiene e evitem contato com outras pessoas, inclusive dividir a bomba”, disse a secretária de municipal de Saúde, Eliane Piffero.
Em São Gabriel (321 km de Porto Alegre), cidade com 38 casos confirmados que suspendeu nesta quinta-feira decreto de situação de emergência, a prefeitura até distribuiu panfletos recomendando evitar o mate em grupo.
Em Uruguaiana (635 km de Porto Alegre), a prefeitura foi mais comedida, mas isso não evitou que a roda de chimarrão passasse a ser evitada.
