The Trouble with Smart Advisors—By Scott Horton (Harper's Magazine)
-
If the Americans and their NATO allies are putting lives at risk to bring democracy to Afghanistan, doesn’t it matter that the government we installed seems to be working to subvert the elections process?

Ants more rational than humans « Biosingularity
-
“This paradoxical outcome is based on apparent constraint: most individual ants know of only a single option, and the colony’s collective choice self-organizes from interactions among many poorly-informed ants,”
-
“It is hard to say. But it’s at least worth entertaining the possibility that some strategic limitation on individual knowledge could improve the performance of a large and complex group that is trying to accomplish something collectively,” Pratt says

LRB · John Lanchester: It’s Finished
-
These feared and despised instruments, whose history has long been of interest to economists, come in three varieties from three issuing banks: the Bank of Scotland, the Royal Bank of Scotland and the Clydesdale Bank. Small countries with big ambitions but few natural resources need ingenious banking systems.
-
In other words, RBS had its origins in a failed speculation, a bail-out, and a financial crash so big it helped destroy Scotland’s status as a separate nation.

The Technium: The Arc of Complexity
-
What's more complex, a cucumber or a Boeing 747? The answer is unknown. We have no way to measure the difference in order and organization between the two and don't have good working definition of complexity to even frame the question. Seth Lloyd, a quantum physicist at MIT, has counted 42 different mathematical definitions of complexity. -
The smallest description of a random number is the random number itself; there is no compression without loss, no way to unpack a particular randomness from a smaller package than itself.

The Mouse Trap: The first 30 seconds: Trustworthiness, Dominance and their neural correlates
-
t is found that some brain regions are consistently more active during encoding of the original stimuli which are later recalled/ recognized correctly. This effect is know as Difference in Memory effect (DM effect). the fact that these areas are differentially engaged during encoding of remembered stimuli as opposed to forgotten stimuli is taken as evidence for the fact that these brain regions are involved in encoding of memory.
-
The results were clear and found that while dmPFC was involved in social evaluations it was not differentially engaged: thus it had a general role to play, perhaps holding the representation of evaluation after it had already been formed; in contrast both amygdala and PCC were differentially recruited and thus underlie the first time evaluations. In the words of the authors: - 3 more annotations...

Graduate School in the Humanities: Just Don't Go - Chronicle.com
-
I usually write back, explaining that in this era of grade inflation (and recommendation inflation), there's an almost unlimited supply of students with perfect grades and glowing letters.
-
- They are excited by some subject and believe they have a deep, sustainable interest in it. (But ask follow-up questions and you find that it is only deep in relation to their undergraduate peers — not in relation to the kind of serious dedication you need in graduate programs.)

Virtual music school becomes a reality
-
As with most computer-aided teaching, the key to developing a musical tuition system is developing superior software able to hear and react to music being played and make judgements as to whether it is being played correctly.
-
Looking to the future, he says now the basic Vemus architecture has been put together it is quite easy to add new musical instruments to the modular system, although it would be more complicated to add polyphonic ones.

Road Map for Financial Recovery: Radical Transparency Now!
-
Even the regulators can't keep up. A Senate study in 2002 found that the SEC had managed to fully review just 16 percent of the nearly 15,000 annual reports that companies submitted in the previous fiscal year; the recently disgraced Enron hadn't been reviewed in a decade.
-
The time to act is now. An exhaustive study by the Transparency Policy Project at Harvard University's John F. Kennedy School of Government—analyzing disclosure rules for everything from restaurant cleanliness to SUV rollover risk—found that there's a very brief window after any calamity for government to institute changes. (Wait too long and the special interests start regaining their confidence and pushing back.)

What Bruce Sterling Actually Said About Web 2.0 at Webstock 09 | Beyond the Beyond from Wired.com
-
And that's your problem, too, here in New Zealand. Far from the action here at the antipodes, you people, you just don't get it about the original principles of Web 2.0! Too often, you've got no architecture of participation, sometimes you don't have an open API! Out here at the end of the earth, you think it's all about drop shadows and the gradients and a tag cloud, and a startup name with a Capital R in the middle of it!
-
Now, I wouldn't want to claim that Web 2.0 is as frail as the financial system -- the financial system that supported it and made it possible! But Web 2.0 is directly built on top of finance. Web 2.0 is supposed to be business.

Recipe for Disaster: The Formula That Killed Wall Street
-
His method was adopted by everybody from bond investors and Wall Street banks to ratings agencies and regulators. And it became so deeply entrenched—and was making people so much money—that warnings about its limitations were largely ignored.
-
Li wrote a model that used price rather than real-world default data as a shortcut (making an implicit assumption that financial markets in general, and CDS markets in particular, can price default risk correctly).

Charlie's Diary: The 21st century: FAQ
-
We're certainly going to see unknown unknowns in the 21st century. Possible sources of existential surprise include (but are not limited to) biotechnology, nanotechnology, AI, climate change, supply chain/logistics breakthroughs to rival the shipping container, fork lift pallet, bar code, and RFID chip — and politics. But there'll be other stuff so weird and strange I can't even guess at it.

The best approach to the singularity is to apply Pascal's Wager — in reverse — and plan on the assumption that it ain't going to happen, much less save us from ourselves.

Demand for human trait selection creates a market
-
As previously noted here on Sentient Developments, demand for the non-medical application of PGD, while small, does exist and it’s increasing. As Jeff Steinberg of LA’s Fertility Institutes says, “This is cosmetic medicine...Others are frightened by the criticism but we have no problems with it.” Trait selection in babies “is a service,” says Dr. Steinberg, and “[w]e intend to offer it soon.”
The Technium: Many Species, One Mind
-
My reading of evolution – as outlined in this blog -- suggests that what organic evolution "wants" is fundamental diversity, as in a diversity of evolutions.
-
if, as Dyson argues in his book, evolution is a type of slow distributed intelligence, then we already have many species, one mind.

When dreaming is believing: Dreams affect people's judgment, behavior
-
surveyed 149 university students in the United States, India and South Korea. The researchers asked the students to rate different theories about dreams. Across all three cultures, an overwhelming majority of the students endorsed the theory that dreams reveal hidden truths about themselves and the world, a belief also endorsed by a nationally representative sample of Americans.
-
This was also the case in another experiment which demonstrated that people who believe in God were likely to consider any dream in which God spoke to them to be meaningful; agnostics, however, considered dreams in which God spoke to be more meaningful when God commanded them to take a pleasant vacation than when God commanded them to engage in self-sacrifice."

Some obvious comments about school improvement and the achievement gap. — Crooked Timber
-
But how are you going to do that? The truth is that while lots of people in the building “know” who the good teachers are, very few people in the building actually know much about what is going on in anyone’s classroom.
-
Doing all this is a lot of work, takes a lot of time and discussion, and requires capacity that lots of schools don’t have readily to hand. For example, many schools do not have people in them who know how to, and are willing to, run a meeting—design a timed agenda, draw in all stakeholders, facilitate discussion among people who have different experiences and real disagreements. Most people, in my experience, don’t even recognise that this is a skill.

Without realizing it, people constantly generate usable data that can then be mined through a variety of methods, from automated sensors in houses to credit card records of shopping habits.
“Everyone in this room pretty much spews data nonstop,” Baker told the crowd.

Your Money - American Express Watched Where You Shopped - NYTimes.com
-
In recent months, American Express has gone far beyond simply checking your credit score and making sure you pay on time. The company has been looking at home prices in your area, the type of mortgage lender you’re using and whether small-business card customers work in an industry under siege.

In the grave new world of the ever-worsening economy, lenders of all sorts are grasping for any sort of information that may shield them from ruin.

Seed: The True 21st Century Begins
-
America's harshly competitive, highly individualistic society has scarcely any grasp of "solidarity." Likely they imagine "Solidarity" has something to do with Polish anti-communism. But no, "solidarity" is a feeling of natural affinity with the unjustly oppressed. One could call it benevolence. Or one could describe it as a wary, street-smart understanding that some fellow citizen just caught it in the neck for no good reason, and that you yourself could easily be next.

If you can't react to the misfortunes of the best people in your society, then, when do you plan to take action? What further excuse do you require to put aside your personal selfishness and learn to think politically?

Physiology physics woven fine: Quantum Biology: The Spooky NanoWorld of Molecules
-
In the molecular world, calculations ‘happen’ in a strange way.
-
Take for example the case of Fluorescent Resonant Energy Transfer or FRET. Also known as Forster Resonant Energy Transfer, this phenomenon is characterized by the emission of a photon of one frequency (upon stimulation) which, in turn, activates an acceptor molecule to emit a photon of another wavelength. There’s one clause that says that the first photon (from the donor molecule) will only be emitted when it can definitively be coupled with the ‘acceptor’. But in the first place, how is this ‘virtual photon’ to know whether its bride was waiting or not when it hasn’t even visited her? Yet FRET doesn’t fret, and the process goes on. - 2 more annotations...
Kevin Kelly -- The Technium
-
It is virtually certain that most US states, if not the federal government, will rush to pass laws prohibiting stealthy DNA sequencing. There is a modern hysteria about DNA that goes in many directions. -
For some folks, the fear of having your DNA stolen is akin to the fear by many tribal people of having their soul stolen by photography. I would argue that getting your DNA sequenced is very much like getting your photo taken. The camera takes your picture and not your soul. And your picture is well… your "picture" is not really yours.
