Small Evidence Kills Big Theory

(p. A5) Paleontologists said Thursday that they had discovered what amounted to a miniature prototype of Tyrannosaurus rex, complete with the oversize head, powerful jaws, long legs — and, as every schoolchild knows, puny arms — that were hallmarks of the king of the dinosaurs.

But this scaled-down version, which was about nine feet long and weighed only 150 pounds, lived 125 million years ago, about 35 million years before giant Tyrannosaurs roamed the earth. So the discovery calls into question theories about the evolution of T. rex, which was about five times longer and almost 100 times heavier.
“The thought was these signature Tyrannosaur features evolved as a consequence of large body size,” Stephen L. Brusatte of the American Museum of National History, an author of a paper describing the dinosaur published online by the journal Science, said at a news conference. “They needed to modify their entire skeleton so they could function as a predator at such colossal size.”
The new dinosaur, named Raptorex kriegsteini, “really throws a wrench into this observed pattern,” Mr. Brusatte said.

Scientist Huxley: “The Great End of Life is Not Knowledge But Action”

John Barry calls our attention to the views of Thomas Huxley who gave the keynote address at the founding of the Johns Hopkins University:

(p. 13) A brilliant scientist, later president of the Royal Society, he advised investigators, “Sit down before a fact as a little child, be prepared to give up every preconceived notion. Follow humbly wherever and to whatever abysses nature leads, or you shall learn nothing.” He also believed that learning had purpose, stating, “The great end of life is not knowledge but action.”

“Recent Temperature Plateau” May Undermine Case for Global Warming

Source of graph: online version of the NYT article quoted and cited below.

(p. A10) The world leaders who met at the United Nations to discuss climate change on Tuesday are faced with an intricate challenge: building momentum for an international climate treaty at a time when global temperatures have been relatively stable for a decade and may even drop in the next few years.

The plateau in temperatures has been seized upon by skeptics as evidence that the threat of global warming is overblown. And some climate experts worry that it could hamper treaty negotiations and slow the progress of legislation to curb carbon dioxide emissions in the United States.
. . .

Underscoring just how little clarity there is on short-term temperature fluctuations, researchers from Britain’s climate change office, in a paper published in August, projected “an end to this period of relative stability,” with half the years between now and 2015 exceeding the record-setting global temperatures of 1998.
Whatever the next decade may hold, critics of global warming have lost no time in using the current temperature plateau to build their case.
“I think it supports the arguments of those who’ve said, ‘What’s the rush for policy on this issue?’ ” said Patrick J. Michaels, a climatologist affiliated with George Mason University and the Cato Institute, a group opposing most regulatory solutions to environmental problems.
. . .

A clearer view of whether the recent temperature plateau undermines arguments for dangerous climate change in the long run should come in a few years, as the predictions made by the British climate researchers are tested. Their paper appeared in a supplement to an August issue of The Bulletin of the American Meteorological Society.
While the authors concluded that there was a 1 in 8 chance of having a decade-long pause in warming like the current plateau, even with rising concentrations of greenhouse gases, the odds of a 15-year pause, they wrote, are only 5 in 100. As a result, the next few years of observations could tip the balance toward further concern or greater optimism.
Meanwhile, social scientists who study the way people understand and respond to environmental problems say it is not surprising that the current temperature stability has created confusion and apathy.

Feds Spent $850,000 to “Green” Buildings, and then Tore Them Down

(p. 4A) WASHINGTON — The four drafty buildings had been fixtures of the Energy Department complex in Oak Ridge, Tenn., for more than half a century. They burned energy like 1950s sedans.

The buildings seemed like perfect candidates for a federal conservation retrofit program that relies on private contractors that receive a percentage of the money they save. A deal was struck in 2001. The contractor reworked lighting and heating systems, among other things, and began collecting payments.

The project was counted among the department’s “green” successes — until auditors discovered that the buildings had been torn down several years ago, and the government had paid $850,000 for energy savings at facilities that no longer existed.

The audit findings show the potential for waste and abuse at a time when the department is poised to launch billions of dollars more in stimulus spending on an unprecedented welter of green projects across the country.
. . .
The problems are not exclusive to Oak Ridge. The auditors, from the department’s inspector general’s office, also determined that $565,000 had been paid over six years under the same arrangement to a contractor in Texas for a highefficiency laundry that was no longer in use.

The department also paid out $3.4 million on another project without checking whether the conservation measures worked — and $160,000 for measurements that were never taken.

Happy Entrepreneur: “Even When Things Get Tough, I’m Still in Control”

“‘Roger the Plumber’ owns his own business and is excited to go to work every day.” Source of caption and photo: online version of the WSJ article quoted and cited below.

(p. D1) By economic yardsticks, Roger the Plumber should be feeling pretty low. Roger Peugeot, owner of the 14-employee Overland Park, Kan., plumbing company that bears his name, is part of a sector hit hard by shrunken credit and slumping sales. He has been forced to reduce staff and is battling new competition from other plumbers fleeing the construction industry.

So why is Mr. Peugeot so happy? He genuinely likes fixing plumbing messes, for one thing, and despite the worst recession he has seen, “I’m still excited to get up and go to work every day,” he says. He relishes running into people at the local hardware store whom he has helped in the past. And in hard times, he says, his fate is in his own hands, rather than those of a manager. “Even when things get tough, I’m still in control,” he says.
In the broadest, most-comprehensive survey yet of how occupation affects happiness, business owners outrank 10 other occupational groups in overall well-being, based on the landmark survey of 100,826 working adults set for release today. Defined as self-employed store or factory owners, plumbers and so on, business owners surpassed 10 other occupational groups on a composite measure of six criteria of contentment, including emotional and physical health, job satisfaction, healthy behavior, access to basic needs and self-reports of overall life quality.
This puts Roger the Plumber well ahead of movers and shakers typically regarded as the top of the heap in society–professionals such as doctors or lawyers, who ranked second, and executives and managers in corporations or government, who came in third–according to the Gallup-Healthways Well-Being Index, a collaboration between Gallup and Healthways, a Franklin, Tenn., health-management concern. This is despite business owners ranking below those more-prestigious occupations in physical health and access to basic needs, such as health care.
. . .
“Despite the recession, it still pays to be your own boss,” says Frank Newport, editor in chief of the Gallup Poll. The survey, adds John Howard, director of the National Institute for Occupational Safety and Health, “reaffirms my view that the more control you have over your work, the happier you are.”

How Wilson and the Feds Turned “Only Influenza” into “The Great Influenza”

Here is the core of John Barry’s account of how President Woodrow Wilson, and his administration, turned what might have been an ordinary flu, into what, by some measures, was the worst pandemic in human history:

(p. 396) . . . , whoever held power, whether a city government or some private gathering of the locals, they generally failed to keep the community together. They failed because they lost trust. They lost trust because they lied. (San Francisco was a rare exception; its leaders told the truth, and the city responded heroically.) And they lied for the war effort, for the propaganda machine that Wilson had created.

It is impossible to quantify how many deaths the lies caused. It is impossible to quantify how many young men died because the army refused to follow the advice of its own surgeon general. But while those in authority were reassuring people that this was influenza, only influenza, nothing different from ordinary “la grippe,’ at least some people must have believed them, at least some people must have exposed themselves to the virus in ways they would not have otherwise, and at least some of these people must have died who would otherwise have lived. And fear really did kill people. It killed them because those who feared would not care for many of those who needed but could not find care, those who needed only hydration, food, and rest to survive.

How Government Universal Health Care Works in India

“Amir Jahan found her health insurance wouldn’t pay for all of her $200 stomach surgery; she continues to work with an untreated tumor.” Source of caption: print version of the WSJ article quoted and cited below. Source of photo: online version of the WSJ article quoted and cited below.

(p. A14) PANIPAT, India — Amir Jahan can spin thick, white thread into magnificent cloth, but the 46-year-old weaver has been unable to unravel her health plan to pay for stomach surgery.

Under a health-insurance program introduced a few years ago, the Indian government has provided health-insurance coverage for the country’s hand-loom weavers, a group of 6.5 million workers, 60% of them female, who are mostly illiterate and invariably poor. Yet holding an insurance card hasn’t helped Ms. Jahan, who says the coverage only pays for minor ailments and not for major problems, such as the removal of a stomach tumor.
“The health care is all a sham,” Ms. Jahan says angrily. “I was refused treatment on grounds of huge expense. I won’t ever go to be humiliated again.”
Ms. Jahan’s health-care issues represent the problems that come with trying to provide insurance to India’s poor. Access to quality care remains a distant dream for many in this country of 1.1 billion.
Last year, the Indian government launched the National Health Insurance Program on (sic) promised health coverage of $700 per person for families earning less than $100 a year.
Holders of health cards have to register in their home states to access benefits, thereby precluding a large population of migrant laborers. Those who can get past the complex state-identification and qualification process often can’t cope with hospital bureaucracies.

Gallup Finds Highest Doubts of Government in Decades

(p. A23) If you want to know why Americans are so fearful of a government takeover of the health-care system, take a look at the results of a new Gallup poll on government waste released Sept. 15. One question posed was: “Of every tax dollar that goes to Washington, D.C., how many cents of each dollar would you say is wasted?” Gallup found that the mean response was 50 cents. With Uncle Sam spending just shy of $4 trillion this year, that means the public believes that $2 trillion is wasted.

In a separate poll released on Monday, Gallup found that nearly twice as many Americans believe that there is “too much government regulation of business and industry” as believe there is “too little” (45% to 24%).
Perhaps most significantly, in both of these polls Gallup found that skepticism about government’s effectiveness is the highest it’s been in decades. “Perceptions of federal waste were significantly lower 30 years ago than today,” say the Gallup researchers. Even when Ronald Reagan was elected president in 1980 with the help of the antigovernment revolt of that era, Americans believed only 40 cents of every dollar was wasted, according to Gallup.
. . .
Over the last decade, the federal government has become bloated and inefficient. Voters are on to the scam. Mr. Obama keeps calling federal spending an “investment,” but Americans apparently feel this is the worst investment they’ve ever made. They’ve come to regard Washington as a $2 trillion Bridge to Nowhere. They are right.

Government Actions Helped Spread 1918 Influenza

Source of book image: http://www.virology.ws/wp-content/uploads/2009/08/great-influenza.jpg

I like John Barry’s The Great Influenza very much, although not entirely for the reasons that I had expected to like it. I wanted to learn more of the details of the worst flu pandemic in history, and the book delivers those details.
But I had not expected that there would be substantial discussion of the epistemology of science and medicine, and of the political and global context that preceded and affected the 1918 H1N1 influenza pandemic.
As an added bonus, the book gives substantial coverage to the life and work of one of my heroes, Oswald Avery. As a result of his research related to the pandemic, he discovered that DNA was the genetic material—a huge milestone in the history of medicine. But he never received the Nobel Prize because the Nobel Committee didn’t want to be seen endorsing controversial work that had not stood the test of time.
On the other hand, the Nobel Committee had no such compunctions about giving the Nobel Peace Prize to President Woodrow Wilson. Barry’s book indicts Wilson for having major responsibility for the severity of the pandemic. His administration drafted huge numbers of young men to fight in WWI, bringing them into close contact in shoddy, incomplete training camps. Some of these young men already had the flu, and they quickly spread it to many of their fellow soldiers. The Wilson administration continued to move these soldiers around the country and to Europe, vastly speeding the spread of the disease.
Barry also documents that the Wilson administration, in the name of patriotism and morale, punished those who told the truth about the severity of the pandemic. The results extended far beyond the trampling of civil liberties. For example, there was a huge parade in Philadelphia to sell war bonds, a parade that could easily have been canceled, but was not—igniting the rapid spread of the disease in that hard-hit city. If the newspapers had been allowed to print the truth about the pandemic, then there probably would have been sufficient outcry to cancel the parade; or at the very least, many better-informed citizens would have avoided the parade, and saved their lives, and the lives of their family members.
There is also a lot in book about the biology of the disease that is of interest, and about the suffering of those who experienced it.
But what I found eye-opening was the extent to which the severity of the disease was due to avoidable actions by Woodrow Wilson and his administration.

Tax Cuts Better Than Stimulus Spending for Raising GDP

(p. A23) The global recession and financial crisis have refocused attention on government stimulus packages. These packages typically emphasize spending, predicated on the view that the expenditure “multipliers” are greater than one–so that gross domestic product expands by more than government spending itself. Stimulus packages typically also feature tax reductions, designed partly to boost consumer demand (by raising disposable income) and partly to stimulate work effort, production and investment (by lowering rates).

The existing empirical evidence on the response of real gross domestic product to added government spending and tax changes is thin. In ongoing research, we use long-term U.S. macroeconomic data to contribute to the evidence. The results mostly favor tax rate reductions over increases in government spending as a means to increase GDP.
. . .
The bottom line is this: The available empirical evidence does not support the idea that spending multipliers typically exceed one, and thus spending stimulus programs will likely raise GDP by less than the increase in government spending. Defense-spending multipliers exceeding one likely apply only at very high unemployment rates, and nondefense multipliers are probably smaller. However, there is empirical support for the proposition that tax rate reductions will increase real GDP.
