In experiment 1, we found that a smoothly coping cognitive system exhibits type positively correlated noise and that its correlated character is reduced when the system is perturbed. This indicates that the participant and tool constitute a self-assembled, extended device during smooth coping and this device is disrupted by the perturbation. In experiment 2, we examine the re-organization of awareness that occurs when a smoothly coping, self-assembled, extended cognitive system is perturbed. We found that the disruption is accompanied by a change in attention which interferes with participants' performance on a simultaneous cognitive task.

Reaction times exhibit a spectral patterning known as 1/f, and these patterns can be thought of as reflecting time-varying changes in attention.We investigated the shot structure of Hollywood films to determine if these same patterns are found.We parsed 150 films with release dates from 1935 to 2005 into their sequences of shots and then analyzed the pattern of shot lengths in each film. Autoregressive and power analyses showed that, across that span of 70 years, shots became increasingly more correlated in length with their neighbors and created power spectra approaching 1/f. We suggest, as have others, that 1/f patterns reflect world structure and mental process. Moreover, a 1/f temporal shot structure may help harness observers' attention to the narrative of a film.

This mounting synchrony between movie pace and the bouncing ball of the mind's inner eye may help explain why today's films manage to seize and shackle audience attention so ruthlessly and can seem more lifelike and immediate than films of the past...

The result is a communal space without fixed function. A softly curvy, feminine expanse without hierarchies or straight lines. A series of calm and silent connected spaces created to nurture collaboration, communication, and cooperation over competition. Library, offices, restaurants, and auditoriums are harmoniously linked between a cloud-like canopy above, and a floor that gently rises and falls like a living organism as it inhales and exhales. "Human movements are not linear like in a train, but curve in a more organic way," said architect Ryue Nishizawa, one-half of team SANAA, explaining his vision. "With straight lines we only create crossroads, but with curves we can create more diverse interactions."

The Regular is a relaxed 'everyday' writing style - Mister K writing down something for himself or to a good friend. The glyphs are fluently con- nected and have lots of form variations without added decorative elements.

The Onstage is Mister K's writing style for less private purposes - special events and persons: Generally more calligraphic, the glyphs have elaborate details especially in the capitals and swashes at the word endings.

The Crossout, finally, shows Mister K's writing when fully dissatisfied with his work - all the words of the text are meticulously crossed out. For especially curious readers texts in 'Crossout' are still readable.

The site allows our small team of explorers to upload short (5-20 min) soundwalks and then enter the following information:

• trace their route with a polyline
• note the time their walk started and finished
• note the recording device used
• note the weather and temperature
• tag their walk to identify some of the key sounds that occur
• make basic comments about the walk

Candide 2.0 is an experiment in the forms of commentary that Voltaire's readers have always been compelled to make on the book. What do we learn about how readers interact with texts and experiment with ways to leave their mark on what they've read? Such questions can be addressed in the margins themselves as a way to communicate with other readers in this public forum.

The letters were among thousands of documents stolen by Guglielmo Libri, an Italian count and mathematician who served as secretary of the Committee for the General Catalog of Manuscripts in French Public Libraries in the 1840s. After learning that he might be arrested, Libri fled to London in 1848 with a collection of 30,000 books and manuscripts, including those by Descartes, Galileo, Fermat, Leibniz, Copernicus and Kepler and other scientific and mathematical giants. 

Claiming to be a political refugee, Libri was welcomed in Britain even though French courts eventually convicted him in absentia in 1850 and sentenced him to 10 years in prison. Libri raised money by selling his collection, and put a total of 7,628 lots up for sale at two auctions in 1861.

Vid sidan av en kundorienterad och en medborgarorienterad biblioteksideologi, funderar jag på om det inte även går att tänka sig en objektsorienterad. Enligt denna existerar biblioteken primärt för böckernas skull (vilket förvisso inte utesluter sekundära syften). Detta kan låta lite magstarkt, men är ändå värt att fundera på.

Enter Bas Edixhoven, a Dutch mathematics professor who conceived the rather marvelous idea of organizing teams of volunteers to re-type all of SGA using modern typesetting software, correcting typos and inserting references to more recent literature where appropriate. Edixhoven secured the blessings of all of Grothendieck's collaborators, but was unable to contact the great man himself, who has spent most of the past two decades in complete seclusion in an unknown location.

But in the many years since Grothendieck retired from mathematics and withdrew from society, he has periodically (though not for several years now) released long, eccentric and beautiful manuscripts containing thousands of pages of mathematics, autobigraphy, philosophy and theology, and these give some clues. (...)

The thrust of his objection--and I am a little hesitant to summarize the subtleties of his position in a single phrase, but here goes--is that everyone's picking the fruit and nobody's tending the garden. Nobody, that is, is doing the sort of deep foundational work that marked Grothendieck's own career. That ongoing disappointment, presumably, has something to do with the letter that arrived last month.

Forskarna har tagit hjälp av professor Göran Possnert vid Ångströmlaboratoriet i Uppsala för att med en så kallad kol 14-analys av proverna ta reda på när kvinnorna dog.

- Enligt denna datering levde den äldre kvinnan redan på 1200-talet innan vare sig Birgitta eller Katarina var född, och den yngre minst 200 år senare, berättar Göran Possnert.

En del av analyserna har gjorts i samarbete med en forskare vid den amerikanska federala polisen FBI:s rättsgenetiska laboratorium i Virginia, USA.

The review-process was a lot more bumpy and time-consuming. The reviewers all liked the way she had handled and analyzed the DNA and only had minor suggestions for improvement in this respect. The radiocarbon dating itself was also ok, but two of the reviewers brought up the "reservoir effect". This could lead to a deviation in radiocarbon dating from the correct age if the two people had been on a high-seafood diet.
