A Dolphin Study Seeks to Start a Two-Way Conversation

Tuesday, October 4th, 2011

A dolphin study seeks to start a two-way conversation:

Dolphins are known to make three types of sounds: whistles, clicks and burst pulses. Whistles are thought to be identification sounds, like names, while clicks are used to navigate and to find prey with echolocation.

Burst pulses, which can sound like quarreling cartoon chipmunks, are a muddy mixture of the two, and Dr. Herzing believes that much information may be encoded in these sounds, as well as in dolphins’ ultra-high frequencies, which humans cannot hear.

The two-way system she will test next year is being developed with artificial intelligence scientists at Georgia Tech. It consists of a wearable underwater computer that can make dolphin sounds, but also record and differentiate them in real time. It must also distinguish which dolphin is making the sound, a common challenge since dolphins rarely open their mouths.

In the new system, two human divers interact in front of dolphins: First they play a synthesized whistle sound, then one hands the other a scarf or a piece of seaweed. The idea is to establish an association between sound and object. Dolphins are excellent mimics, and the hope is that they will imitate the whistle to request an object or initiate play.

“I think if they pick up on it,” Dr. Herzing said, “they’re going to be excited and say, ‘Oh, my gosh, now I have the power to get what I want in real time.’ ”

Still, she is quick to play down expectations, noting that the system is still in development.

“We’re not talking to dolphins,” she said, adding, “We’ll keep it simple and then we can potentially expand it.”

And while other researchers praise her work, they point out that of dolphin-human communication has often fallen short of expectations.

“It depends on what you mean by communicate,” Dr. Kuczaj said. “I can communicate with my dog, too. But do I have conversations with my dog? Well, if I do they’re very one-sided.”

How the Communists could have taken all of Western Europe

Monday, October 3rd, 2011

While discussing psychological operations in Iraq, William S. Lind shares a story about his dad:

Years ago, my father, David Lind, whose career was in advertising, said, “If the day World War II ended, Stalin had sent all his German prisoners home, giving them a big box of food for their families and a wallet full of Reichsmarks, the Communists would have taken all of Western Europe.” He may have been right.

A Little Deception Helps Push Athletes to the Limit

Monday, October 3rd, 2011

A little deception helps push athletes to the limit:

In a new study, Dr. Thompson tried to find what that limit is.

He used the same method as before: Cyclists on stationary bikes raced an on-screen avatar going a bit faster than the cyclist’s own best time. In one group, the only variable was competition. Cyclists were told that the avatar would be going 2 percent faster or 5 percent faster than the cyclist had ever gone.

The other group was deceived. Each cyclist was told to compete against an avatar that would be moving as fast as that athlete had in his best effort. Actually, the avatar was programmed to race 2 percent harder or 5 percent harder. (A 5 percent increase in power translates into a 2 percent increase in speed, Dr. Corbett said.)

The cyclists in the first group gave up from the start when they knew the avatar would be moving faster than they ever had — even when the avatars were going 2 percent harder than the cyclists’ own best times. Instead, the athletes matched their own best efforts.

As had been observed in previous experiments, cyclists in the second group, who were deceived, kept up with their avatars when they were programmed to perform 2 percent harder than each athlete at his best. But 5 percent was just too much: The athletes kept up for about half the race, then gave up.

In the end, their overall pace was no better than it had been in their best effort without the avatar. Some seemed to do even worse than their previous best effort.

“It comes back to the belief system within the athlete,” Dr. Thompson said. Within limits, if an athlete thinks a certain pace is possible, he or she can draw on an energy reserve that the brain usually holds in abeyance.

One lesson, Dr. Thompson said, is that coaches can eke better performances out of athletes by means of small deceptions.

When an athlete has reached a plateau, a coach might tell an athlete in a training session that the course distance is slightly shorter than it actually is, for example, or that his or her speed at each interval is slightly slower than it is.

The new research suggests that this strategy may bring about an increase in performance, and Dr. Thompson said that it has been used to coach elite middle-distance athletes, although he declined to provide details.

The Dictator’s Handbook

Monday, October 3rd, 2011

Bruce Bueno de Mesquita has decided to popularize his ideas with a new book, The Dictator’s Handbook, co-written with Alastair Smith. Michael Moynihan reviews the “lucidly written, shrewdly argued meditation on how democrats and dictators preserve political authority”:

So how is it that undemocratic leaders — who exploit, imprison and brutalize their subjects — frequently maintain power for far longer periods than their democratic counterparts? Autocrats, the authors argue, need only reward only a small class of loyalists — the army, judiciary, an inner circle of advisers — who will reliably suppress opposition. While democrats likewise dispense rewards — sweetheart contracts, farm subsidies, welfare payments — they are constrained by a system of government that requires the loyalty of fickle voters. This ensures that if a leader accumulates wealth and power in a few hands, his job security weakens.

In a style reminiscent of “Freakonomics,” Messrs. Bueno de Mesquita and Smith present dozens of clever examples of how researchers identify and compare graft in autocracies and democracies. The authors demonstrate, for instance, that roads connecting airports to major cities in democracies tend to be circuitous, zigging and zagging across the landscape, while in autocracies they tend to be fairly straight. Why? Because autocrats are less likely to respect the property rights of those inhibiting their public-works plans. Powerless peasants, after all, are hardly in a position to threaten government authority. In a democracy, a large-scale use of eminent domain would be wildly unpopular, probably resulting in the ruling party’s replacement.

One might presume that a badly handled natural disaster greatly shortens time in office. It does — but only in democracies. Dictators, the authors argue, should view mass death by natural disaster as good politics. This is a jarring assertion, but consider that the higher the death toll in a democracy, the less likely an incompetent government is to be re-elected. The higher the death toll in an autocracy, however, the more money leaders can extract from foreign governments and aid agencies, money that is then used to strengthen the position of government loyalists.

And how about those well-meaning debt-forgiveness campaigners? While it might seem intuitively true that clearing balance sheets helps poor countries, “The Dictator’s Handbook” suggests that pardoning debt obligations tends to entrench authoritarian leaders and retard the development of democracy. With a wounded economy, autocrats find it more difficult to bribe their small group of key supporters.

The most fascinating chapter in “The Dictator’s Handbook” concerns the rewards that governments provide other governments. The authors make the obvious, but nevertheless controversial, argument that almost all aid money is dispersed not to alleviate poverty but to purchase loyalty and influence. There also exists an important political calculus for autocratic aid recipients, who are often willing to make unpopular domestic political decisions provided that the benefits are ample enough to satiate those loyalists who sustain their power.

Consider that democratic Turkey refused the Bush administration’s request to use its military bases for an attack on Iraq. After long and labored negotiations, Ankara calculated that the offered financial reward wasn’t enough to risk alienating its political reputation with its own people, who can simply retaliate at the ballot box. Instead, American planes flew from autocratic Kuwait, a government with a very small power base — and one that needn’t answer to an angry electorate.

Not a Sign of Societal Health

Monday, October 3rd, 2011

Middle-class Americans need to be taught to be more, rather than less, aggressive in self-defense situations, Glenn Reynolds believes, and he cites Jeff Cooper (from To Ride, Shoot Straight, and Speak the Truth) on how you might feel if you kill someone in self-defense:

We are told from all sides that if one wins a lethal encounter, he will feel dreadful. It is odd that no one seems to have felt dreadful about this until very recently. Throughout recorded history the winning of a fight has generally been considered a subject for congratulation. It is only just now that it has become presumably tainted…. a predatory felon who victimizes innocent non-combatants on the streets is a proven goblin, sentenced by his own initiative. Some men may be upset by killing him, but not anyone I have met.

Reynolds continues:

Cooper suspects that this dreadful feeling is “primarily a public relations innovation designed to parry various sorts of preposterous litigation which have become common in our courts.” That’s probably right, and defenders are probably well-advised to fake devastation even if they really feel much better about the whole thing. That such fakery is required, however, is probably not a sign of societal health. As Cooper writes, “This sudden notion that there is something disreputable about winning in mortal conflict is peculiar and, I think, aberrant.”

Jules Aimé adds his own experience:

In the fall of 1990 I was walking by the gas station on the corner of Bank and Catherine streets in Ottawa when I saw a guy pull a knife and brandish it at the teenaged gas jockey. I stepped in between the kid and the guy and he turned away started running up Bank Street. But then he stopped and came at me.

The fight was very one-sided in the end. The guy managed to get a few hits in, including a kick in the head when I threw him down on his back and started to pin him, but it didn’t do him any good. I was stronger, faster and smarter. He didn’t have a chance. When the police arrived (they got there in about three minutes, which is impressive), I had the guy pinned down on the sidewalk and all they had to do was cuff him and throw him in the car.

I felt and feel very good about it. I was a young, single man and I did what a man is supposed to do.

But I got a rude shock a few years ago. I got a call from the police. The guy I had captured had been arrested again in Calgary. It was only the latest in a long-line of arrests for violent crimes and they wanted to sentence him as a dangerous offender. The officer who called me wanted to know if I’d be willing to testify about the effects this encounter had had on me. She assumed the effects were devastating.

I told her that it was one of the great events of my life. I’d been tested and I’d done the right thing and I’d passed the test. I’d behaved up to the standard that I think men should behave and you never really know how you are going to act until you are actually tested that way. She was surprised to hear this. The file she had, the file the investigating officer wrote up, described me as a victim.

Why Blame Us?

Sunday, October 2nd, 2011

Why Blame Us?, Americans wonder, when Haitians or Iraqis kill each other:

As Martin van Creveld writes in his important book, The Rise and Decline of the State, the state arose, in Europe starting in the 15th century, to bring order. Not freedom, not capitalism, certainly not democracy, but order. Between the decline of the High Middle Ages and the rise of the state, Europe was plagued by disorder, often in the form of roving bands of armed men looking for employment as soldiers. Being skilled in the use of arms and semi-organized (and not having much to lose anyway), if they saw something they wanted, they took it. That meant not only money but the food a family had stored to get it through the winter, along with their warm house; women; boys and young men, to fill up their ranks; horses and other livestock; in short, anything. What they did not steal they destroyed, just for the fun of it. And seeing how long they could keep someone alive under torture often provided an evening’s entertainment. Life was Hobbesian — nasty, brutish and short — for anyone without a castle.

The state promised to restore order, and in time it did. As the state spread throughout the world, usually in the form of European colonialism, it made that same promise good beyond Europe. While the state added qualities beyond order as it developed, its legitimacy still depended on upholding its first promise, maintaining order. And it still does so depend.

That is why, in countries such as Iraq and Haiti, the locals blame us when order breaks down. As the occupying power, we are responsible for maintaining order. That is true under international law as well as in the eyes of the local people. We are the state now in those places, and when order breaks down, we — the state — have failed.

The state also has trouble maintaining order near William S. Lind’s office on Capitol Hill in Washington, D.C.

Driving the Rich into the Sea

Sunday, October 2nd, 2011

Scott Adams (Dilbert) predicts that confiscatory taxes will soon drive the rich into the sea — to seasteads, that is:

In the old days, every member of the middle class thought he or she had a chance of becoming rich. In that sort of optimistic environment, you don’t want to urinate in the pool that you hope to someday swim in. But lately there’s more fatalism in the air, thanks to our crushing debt and the hobo militias that I assume are forming all over the country. The middle class will soon trade their unrealistic dreams of wealth for the opportunity to transfer money from total strangers to themselves — a process often referred to as fairness. That’s when the rich will get serious about an escape plan, just like the brave little sea creatures billions of years ago.

But where can the rich go? Their choices include nations that have swarms of malaria-infested mosquitoes, bad TV, deadly climates, decapitation issues, French people, bland food and other signs of inhospitableness. When you consider these factors plus wars, pollution, terrorism, floods, droughts, earthquakes and tornadoes, I think you’ll agree that most of the surveyed land on Earth is unfit for fancy people.

This is where technology trends come in. We’ve already entered the era of megaships, including plans for island-size vessels with permanent homes and businesses. We’ll soon see rapid advances in high-speed Internet for seafaring vessels, floating fisheries, hydroponic gardens, energy generated from waves, and desalination. The only other element needed to trigger mass migration of the wealthy to the oceans is a financial motive. If a billionaire can escape taxation by leaving his dirt-based country behind, he’ll save more than enough money to pay for his floating fortress of awesomeness.

Out at sea, you can declare your own sovereign state or form alliances with other island-vessels. Taxes would be a thing of the past. Any government-like decisions can be handled through a Facebook page. The only downside would be listening to Ron Paul nagging you to use Twitter instead to keep government small.

Pirates would be a cause of concern, obviously. But if a billionaire has enough money to buy an island-size vessel, he probably has enough to outfit it with a drone air force, radar, sonar, laser guns, torpedoes, ship-to-ship missiles, and other technology so cool that just thinking about it raises my testosterone count.

A Brontosaurus with Three Teeth

Saturday, October 1st, 2011

What does the return of mercenaries tell us? It tells us, William S. Lind says, that state militaries have become so bureaucratic, expensive, and top-heavy that they are losing the ability to fight:

As expensive as mercenaries are — and the Post article quotes a figure of $1,000 per day for skilled bodyguards — they are still cheaper than state military forces. This is not because the U.S. Army overpays its privates and sergeants, but because the $400 billion America pays each year for defense buys very few privates and sergeants in the combat arms, guys who can actually fight.

Most of the money goes for overhead: contractor welfare in the form of multi-billion dollar programs for irrelevant weapons like the F-22, endless consultants (most retired generals and colonels who already collect large pensions), a bloated officer corps above the company grades, a vast rear area made ever-larger by the needs of complex, computerized “systems,” and layer upon layer of headquarters, each with a small army of horse-holders and flower-strewers.

If you want to imagine a modern state military (others differ from our own only in degree), think of a brontosaurus with three teeth.
