This is at P.S. 1 a sculpture that's basically a square room by James Turrell, that has a retractable ceiling.

Then the animal learns to walk on a leash in the open and find targets.

When I was 22 years old, I came home from work, put a leash on my dog and went for my usual run.

She will govern a country with substantial public debt (60 of GDP), a volatile currency, and high inflation. Nervous financial markets will keep the government on a tight leash.

She wrote all her own software to design and built this DNA origami, a beautiful rendition of China, which even has Taiwan, and you can see it's sort of on the world's shortest leash, right?

So pressure outside the US and Britain to put the hedge fund industry on a tighter regulatory leash is hardly surprising. The Germans, for example, want to reduce risk by forcing hedge funds to adhere to stricter reporting requirements.

But in a labor strong society, dominant shareholders those with the most to lose if expansion goes awry have reason to keep managers on a short leash. Italy's Fiat illustrates the problem even a conservative government seeks to impede downsizing.

As the Soviet Union steadily disintegrated, with virtually all of its 15 republics straining at the leash, Yeltsin gained the leadership of the largest the Russian Federation which placed him in a tactical alliance with independence campaigners in Ukraine, the Baltic states, and Georgia.

Ordinary Libyans have also advocated keeping women on a short leash. A college age Libyan woman s father recently denied her the opportunity to accept a scholarship from the US State Department to attend a training workshop in Washington, DC, because he could not accompany her overseas.

In the case of Italy, the short leash would dissuade former Prime Minister Silvio Berlusconi from seeking to topple Mario Monti s new government (which has only a fragile majority), because if Berlusconi precipitated an election, the electorate would punish him. This would help to reestablish political stability and accelerate Italy s return to the market.

One obvious objection to this strategy is that it would reduce the average maturity of Italian and Spanish debt. I believe that, on the contrary, this would be an advantage in the current exceptional circumstances, because it would keep the Italian and Spanish governments on a short leash no country concerned could afford to lose the ECB facility.

The importance of these structures is that they insulate the central bank s monetary policy independence from corruption by the tighter accountability requirements that inevitably come with banking supervision. Because supervisors decisions affect individuals property rights and their actions or omissions can put taxpayers on the hook to bail out banks governments, parliaments, and the courts are bound to hold the watchdogs on a tight leash.

It is one thing to believe that governments act only under pressure, and that societies accept reforms only if they believe that there is no other alternative it is quite another to believe that adjustment and reform will proceed if all of Southern Europe is struggling with recession. Keeping Southern Europe on a short leash would be a more credible strategy if accompanied by a growth program for the entire eurozone.
