What works best for lower back pain

The surprising thing about this study is that anyone thought it was surprising …
What's the best Rx for lower-back pain?: Scientific American Blog 
We did an evaluation of high quality studies on the prevention of back problem episodes in adults [and] found that, surprisingly, exercise is the only intervention that works, and other popular interventions don't work," says Stanley Bigos, emeritus professor of orthopedic surgery at the University of Washington in Seattle, and lead author of the analysis published recently in The Spine Journal. .. 
… Exercises such as lifting free weights and doing leg and trunk lifts to fortify core muscles proved effective at staving off pain, Bigos says. The studies in the review focused mainly on exercises to build muscle strength and endurance – not intense cardio workouts, but Bigos says that speed walking, cycling, and other activities that increase heart rate and improve overall fitness also benefit back health.
Only an orthopedic surgeon could be surprised by this study.

My recollection is that exercise and fitness has been considered the best way to manage lower back pain for at least fifteen years. What’s a bit more controversial is how much strengthening is really needed (and thus worth paying for). When I finally decided to rehab my own back I opted for the extreme strengthening approach of a local team – the Physicians Neck and Back Clinic.

I suspect their regimen is far beyond anything Bigos looked at, but I think they’re probably on the right trail.

The Icelandic antidote to optimism

I was feeling oddly optimistic the other day, as though we were turning the corner in the global economic meltdown.

Then I read the ubiquitous Michael Lewis in (yes) Vanity Fair – describing a world class lunacy. The lunacy of the The Rise and Fall of Iceland (emphases mine) …

Wall Street on the Tundra | vanityfair.com

Iceland’s de facto bankruptcy—its currency (the krona) is kaput, its debt is 850 percent of G.D.P., its people are hoarding food and cash and blowing up their new Range Rovers for the insurance—resulted from a stunning collective madness. What led a tiny fishing nation, population 300,000, to decide, around 2003, to re-invent itself as a global financial power?…

… Just after October 6, 2008, when Iceland effectively went bust, I spoke to a man at the International Monetary Fund who had been flown in to Reykjavík to determine if money might responsibly be lent to such a spectacularly bankrupt nation … a nation of extremely well-to-do (No. 1 in the United Nations’ 2008 Human Development Index), well-educated, historically rational human beings who had organized themselves to commit one of the single greatest acts of madness in financial history..

… In 2003, Iceland’s three biggest banks had assets of only a few billion dollars, about 100 percent of its gross domestic product. Over the next three and a half years they grew to over $140 billion …

… From 2003 to 2007, while the U.S. stock market was doubling, the Icelandic stock market multiplied by nine times. Reykjavík real-estate prices tripled. By 2006 the average Icelandic family was three times as wealthy as it had been in 2003, and virtually all of this new wealth was one way or another tied to the new investment-banking industry…

… When their three brand-new global-size banks collapsed, last October, Iceland’s 300,000 citizens found that they bore some kind of responsibility for $100 billion of banking losses—which works out to roughly $330,000 for every Icelandic man, woman, and child. On top of that they had tens of billions of dollars in personal losses from their own bizarre private foreign-currency speculations, and even more from the 85 percent collapse in the Icelandic stock market…

… In the end, Icelanders amassed debts amounting to 850 percent of their G.D.P. (The debt-drowned United States has reached just 350 percent.)…

… The point is reinforced by a 26-year-old Icelander I’ll call Magnus Olafsson, who, just a few weeks earlier, had been earning close to a million dollars a year trading currencies for one of the banks….

… That was the biggest American financial lesson the Icelanders took to heart: the importance of buying as many assets as possible with borrowed money, as asset prices only rose. By 2007, Icelanders owned roughly 50 times more foreign assets than they had in 2002…

… They bought stakes in businesses they knew nothing about and told the people running them what to do—just like real American investment bankers! For instance, an investment company called FL Group—a major shareholder in Glitnir bank—bought an 8.25 percent stake in American Airlines’ parent corporation…

Nor were the Icelanders particularly choosy about what they bought. I spoke with a hedge fund in New York that, in late 2006, spotted what it took to be an easy mark: a weak Scandinavian bank getting weaker. It established a short position, and then, out of nowhere, came Kaupthing to take a 10 percent stake in this soon-to-be defunct enterprise—driving up the share price to absurd levels. I spoke to another hedge fund in London so perplexed by the many bad LBOs Icelandic banks were financing that it hired private investigators to figure out what was going on in the Icelandic financial system. The investigators produced a chart detailing a byzantine web of interlinked entities that boiled down to this: A handful of guys in Iceland, who had no experience of finance, were taking out tens of billions of dollars in short-term loans from abroad. They were then re-lending this money to themselves and their friends to buy assets—the banks, soccer teams, etc. Since the entire world’s assets were rising—thanks in part to people like these Icelandic lunatics paying crazy prices for them—they appeared to be making money. Yet another hedge-fund manager explained Icelandic banking to me this way: You have a dog, and I have a cat. We agree that they are each worth a billion dollars. You sell me the dog for a billion, and I sell you the cat for a billion. Now we are no longer pet owners, but Icelandic banks, with a billion dollars in new assets. “They created fake capital by trading assets amongst themselves at inflated values,” says a London hedge-fund manager. “This was how the banks and investment companies grew and grew. But they were lightweights in the international markets.”

On February 3, Tony Shearer, the former C.E.O. of a British merchant bank called Singer and Friedlander, offered a glimpse of the inside, when he appeared before a House of Commons committee to describe his bizarre experience of being acquired by an Icelandic bank.

Singer and Friedlander had been around since 1907 and was famous for, among other things, giving George Soros his start. In November 2003, Shearer learned that Kaupthing, of whose existence he was totally unaware, had just taken a 9.5 percent stake in his bank. Normally, when a bank tries to buy another bank, it seeks to learn something about it. Shearer offered to meet with Kaupthing’s chairman, Sigurdur Einarsson; Einarsson had no interest… When Kaupthing raised its stake to 19.5 percent, Shearer finally flew to Reykjavík to see who on earth these Icelanders were. “They were very different,” he told the House of Commons committee. “They ran their business in a very strange way. Everyone there was incredibly young. They were all from the same community in Reykjavík. And they had no idea what they were doing.”

He examined Kaupthing’s annual reports and discovered some amazing facts: This giant international bank had only one board member who was not Icelandic, for instance. Its directors all had four-year contracts, and the bank had lent them £19 million to buy shares in Kaupthing, along with options to sell those shares back to the bank at a guaranteed profit. Virtually the entire bank’s stated profits were caused by its marking up assets it had bought at inflated prices

… In a sane world the British regulators would have stopped the new Icelandic financiers from devouring the ancient British merchant bank. Instead, the regulators ignored a letter Shearer wrote to them. A year later, in January 2005, he received a phone call from the British takeover panel. “They wanted to know,” says Shearer, “why our share price had risen so rapidly over the past couple of days. So I laughed and said, ‘I think you’ll find the reason is that Mr. Einarsson, the chairman of Kaupthing, said two days ago, like an idiot, that he was going to make a bid for Singer and Friedlander.’” In August 2005, Singer and Friedlander became Kaupthing Singer and Friedlander, and Shearer quit, he said, out of fear of what might happen to his reputation if he stayed. In October 2008, Kaupthing Singer and Friedlander went bust…

… Icelanders—or at any rate Icelandic men—had their own explanations for why, when they leapt into global finance, they broke world records: the natural superiority of Icelanders. Because they were small and isolated it had taken 1,100 years for them—and the world—to understand and exploit their natural gifts, but now that the world was flat and money flowed freely, unfair disadvantages had vanished. Iceland’s president, Olafur Ragnar Grimsson, gave speeches abroad in which he explained why Icelanders were banking prodigies. “Our heritage and training, our culture and home market, have provided a valuable advantage,” he said, then went on to list nine of these advantages, ending with how unthreatening to others Icelanders are. (“Some people even see us as fascinating eccentrics who can do no harm.”) There were many, many expressions of this same sentiment, most of them in Icelandic. “There were research projects at the university to explain why the Icelandic business model was superior,” says Gylfi Zoega, chairman of the economics department. “It was all about our informal channels of communication and ability to make quick decisions and so forth.”

“We were always told that the Icelandic businessmen were so clever,” says university finance professor and former banker Vilhjalmur Bjarnason. “They were very quick. And when they bought something they did it very quickly. Why was that? That is usually because the seller is very satisfied with the price.”

You didn’t need to be Icelandic to join the cult of the Icelandic banker. German banks put $21 billion into Icelandic banks. The Netherlands gave them $305 million, and Sweden kicked in $400 million. U.K. investors, lured by the eye-popping 14 percent annual returns, forked over $30 billion—$28 billion from companies and individuals and the rest from pension funds, hospitals, universities, and other public institutions. Oxford University alone lost $50 million…

It’s flat out insane, and it makes me rethink the ordering of my 10 causes of the collapse of 2008. As Lewis wrote previously

… when Eisman bought a credit-default swap, he enabled Deutsche Bank to create another bond identical in every respect but one to the original. The only difference was that there was no actual homebuyer or borrower. The only assets backing the bonds were the side bets Eisman and others made with firms like Goldman Sachs. Eisman, in effect, was paying to Goldman the interest on a subprime mortgage. In fact, there was no mortgage at all. “They weren’t satisfied getting lots of unqualified borrowers to borrow money to buy a house they couldn’t afford,” Eisman says. “They were creating them out of whole cloth. One hundred times over! That’s why the losses are so much greater than the loans. But that’s when I realized they needed us to keep the machine running. I was like, This is allowed?”...

Financial operators around the world seemed to have discovered a way to effectively print money, a role usually reserved for central banks and counterfeiters. There’s been so much money floating around, it periodically dumps millions and billions here and there.

No wonder Geithner is very reluctant to tell us how bad things are.

Incidentally, my favorite part of the story was how the newly wealthy people of Iceland rationalized their success. I’d love to know the “nine advantages”, though I sympathize. It’s only human to assume success is merited and failure is not.

Update: In a separate article in VF Icelanders point out quite a few egregious errors in the article. Happily, the errors were in sections I didn't excerpt. Incidentally, Vanity Fair (!) has an article entitled Madoff's World. It deserves to be read alongside the Iceland story to get the full flavor of our era.

Apple again delivering value for the dollar

Last January Apple's value proposition was out of whack -- with the sole exception of their almost invisible plastic MacBook ...

Gordon's Notes: iMacs are expensive

We'd like to reorg our home office. That means I need at least the same computing capability in half the space.

The best way to do that is to ditch my 5 yo big-old XP box and monitor, and replace it with a 24" iMac that will run Fusion/XP and OS X, using the monitor as a 2nd display...

Problem is, that will cost me about $2,400 with appropriate RAM.

Or I could get a Mac Mini and forgo the 2nd display. There the price is quite good, but the memory capacity and processor speed are currently on the low side -- and rumor is that the next generation will sacrifice CPU to make the Mini smaller and cooler. Of course Apple will also drop the firewire connection, so performance will take another big hit.

I'd buy a more powerful Mac Mini that would sell for, say $800 base and $1000 or so with 4GB. I'd attach an external firewire hard drive and/or a NAS....

So how's the Mac Mini look today?

If I use Apple's memory (historically costly, now reasonable) I can get

  • 4 GB RAM
  • Firewire 800*
  • 2 GHz Core 2 Duo
  • iLife '09

for $750 (list, direct from Apple Store).

Well, I'm impressed. That's $250 less than what I thought would be good value in January.

And an iMac with 4GB and 24" display? At $1,500 my desired machine is $900 less than it was two months ago.

That's aggressive pricing for my "market of one".

* So is Apple admitting they made a mistake dropping Firewire from the MacBooks without at least offering USB 3?

Update 3/3/09: The bargain iMac doesn't have a dedicated GPU; in that regard it's a step back from the the $2,400 Jan price. So it's not really a $900 savings for the same machine; maybe it's a $700 saving. Still, pretty darned good. I'm curious as to whether Snow Leopard will be able to make use of the GPU computing engine on the $1,500 iMac.

Update 5/3/09: It's not clear how well Aperture runs on the lower tier iMacs. The more I look at them the less impressive they seem. Apple fooled me on this one.

Against the crash - why I'm optimistic

Just a few months ago Paul Krugman thought 2010 looked pretty good...

Krugman - Life Without Bubbles - Dec 2008

... Late next year the economy should begin to stabilize, and I’m fairly optimistic about 2010....

Not so much recently ...

Failing the test - Paul Krugman Blog - Mar 2 2009

It’s a depressing spectacle: on both sides of the Atlantic, policy-makers just keep falling short — and the odds that this slump really will turn into Great Depression II keep rising.

In Europe, leaders rejected pleas for a comprehensive rescue plan for troubled East European economies..

... Oh, and Jean-Claude Trichet says that there is no deflation threat in Europe...

... On this side of the Atlantic, Tim Geithner seems committed to the view that banks should stay private even if they’re bankrupt, because — well, just because...

Personally, I'm strangely optimistic. I even suspect Krugman is more optimistic than he seems -- he has to keep the heat on because he can. I don't have to worry about misusing influence.

So where does the optimism come from?

Quickly ...

  • Yes, the big banks and most of Wall Street was crazed and stupid, and we're funneling money from the worst to the almost as bad. On the other hand, although much value was illusory, some people won real things. So at the end of the day who's far ahead, in real terms, of where they were in 1994? China, Russia and India. That's a lot of poverty alleviated, and a lot of creativity engaged.
  • Based on share price we're more or less back in 1997. Does anyone think our productive and global capacity is the same as 1997? No bloody way. Shares were a bit out of line in 1997, but they didn't go crackers until 1999. Today shares are underpriced.
  • There's a huge amount of technological innovation in the pipeline, and we're going to need it to survive climate changes and population explosion. So there's innovation supply, huge innovation demand, and work to do.
  • We've only begun to exploit the power of computing and communications technology. We're roughly at the same stage as early electrification or the early telephone. The big gains are ahead.
  • The world is more or less at peace these days.
  • Obama. Damn, we didn't deserve that piece of luck.
  • The causes of the crash are fixable: My best take is that there were at least 10 reinforcing contributing factors. In other words, the crash of 2008, like murder and abortion rates and mega-terrorism, was a non-linear (chaotic system) outcome. It's not fully predictable, but, given the reinforcing causes it was highly likely. That means, like murder rates, it can reverse course dramatically.
  • Marketarianism: Sure, I mock the Marketarians and their mystical belief in the power of markets to solve problems. On the other hand, we're in the territory where self-preservation and markets tend to line up. Krugman isn't in a position to say "we don't understand the economic system we exist in", but since I know far less about economics (but perhaps more about humility?) I can say that. We don't understand the vastly complex world economic system. That leaves some room for Marketarian optimism.
  • The X-Factor: I really don't see how a swarming nest of violent primates survived the development of fusion weapons. There's clearly something going on here I don't get.
  • Limbaugh and the Party of Limbaugh are outraged by Obama's fixes. So they must be good.

So color me optimistic.

Hydrotouring via Lunocet

Why not?
Dolphin-Inspired Man-Made Fin Works Swimmingly: Scientific American

.... Using the Lunocet, some swimmers are close to being able to breach completely out of the water, like whales. Ciamillo envisions a new high-speed, free-diving community of swimmers united around 'hydrotouring': long-distance swimming expeditions using Lunocets to cover dozens of miles a day, with participants carrying streamlined, waterproof packs containing only a global positioning system (GPS), satellite phone, and enough food and water for a few nights on shore...

What did the GOP lose besides the election?

Talking Points Memo | Non-Custodial Visits?

Dems gloat after Rush awards himself sole custody of Steele's testicles.
Ok, so maybe Olympia Snowe still has a testicle or two. The rest of the party sings soprano now.

St Paul Pioneer Press listed on the next 10 to die list

My home town paper slips onto the list next to biggies like the SF Chronicle and the LA Times ...

The Next 9 Newspapers To Die

...St. Paul Pioneer Press – Circulation: 184,973 (3% decrease since 2007)...

Minneapolis, our sister city, has the Star Tribune. It's bankrupt of course, but for the moment it only has to outlive the Pioneer Press.

Both papers are a shadow of their former selves.

In my Canadian childhood we had record players, tape recorders, carbon paper, broadcast ad-supported television, VCRs, pay phones, pay toilets (!) and I delivered 3 different varieties of heavy newspaper by bicycle (I must have been stronger than I remember).

All anachronisms (nobody misses the pay toilets).

It's absurd to schlep newsprint from printer to doorstep. I personally won't miss the end of the newspaper.

The trick will be to kill the newspaper but, somehow, preserve the business of written news.

When giants walked the earth ...

Scott, Amundsen, Shackleton, Nobile ... not the same breed as me ...

Looking for Amundsen - NYTimes.com

... In March 1912, before it was clear that Amundsen had beat Scott to the South Pole (and that Scott had died after reaching it), the explorer Ernest Shackleton sent a cable to The Times, wondering whether Amundsen had marched to the pole “in northern furs or in the light, windproof burberry that we found successful.” The answer was northern furs. In the end, the most important equipment for all these explorers was their indomitability.

What will we learn if Amundsen’s plane is found? Where things went wrong and perhaps also what. The tribute we pay to great explorers is to send other explorers out in search of them. That’s how it is for Amundsen. As for Nobile, he was eventually rescued and died at the age of 93 in 1978.

Redoing automobile distribution - the very old is new again

My parents live in the old country - Quebec. GrandCentral means frequent free cell phone calls to my mother, but Dad's not keen on phone conversation. I catch up with him every few months. This weekend that means learning lessons from the early 20th century.

That's how I learned that cars were once sold without the back seats -- in order to save costs. More importantly, after WW II, while factories were converting to consumer production, consumers ordered automobiles and waited for delivery.

Hmm. I recall there was some interest in the 90s in just-in-time custom auto manufacturing and online ordering, but it died with the .com crash. That doesn't mean it won't return -- most big changes have several false starts.

Maybe the way we sell automobiles, like the the way we've sold written news, is an anachronism due for an ending.

Maybe after the wreckage is done, and most of big auto is gone, we'll start selling, manufacturing and distributing cars in a new old way. Or perhaps a need to rapidly upgrade to low carbon technology will favor leased vehicles with reusable components...

What does the rise of Limbaugh's party mean for the religious right?

I've never heard Rush (big fat idiot) Limbaugh directly. Heck, I've barely listened to any AM talk radio hosts* -- I don't even like NPR's talk radio. The only talk radio I can tolerate is the BBC's "In Our Time", and I gather Limbaugh is not Melvyn Bragg.

It's a failing. I don't mind listening to religious rantings; from what I've seen of the world any affiliated deity could be quite vengeful, irrational and nasty. The sheer stupidity of talk radio though -- it's too much.

And I'm an aging white male! These guys are talking to my (seeming) tribe.

Which is to say that I really don't know what Rush Limbaugh's ownership of the GOP means for the Party of Limbaugh's political strategy. It seems to fit with the "Southern Strategy" (white racism), but I don't think Limbaugh is a great fit for the religious right. I rarely hear him mentioned in that context, and my quick googles found mostly awkward defenses of Limbaugh's religious credentials from right side bloggers.

So does this mean the Party of Limbaugh is separating from the religious right? I'd like to see some commentary on that ...

Jindal - the GOP's gift to the nation

I don't thank the GOP for much, but I do have to credit them for an unsuspected sense of humor.

How did they know Jindal was just the comic relief we needed?

Inventing stories of personal faux heroism (remember how the GOP savaged John Kerry for relatively minor discrepancies in true stories of military action?), alienating the entire Coast Guard by claiming government did nothing for victims of Katrina (they were heroic), mocking federally funded research on (wait for it ...) volcanic eruption prediction ...

Phew! Pardon me while I wipe a tear from my eyes. That was a comic tour de force. But Frank Rich tells us there was even more...
Frank Rich - The Ecstasy and the Agony - NYTimes.com

... Listening to Jindal talk Tuesday night about his immigrant father’s inability to pay for an obstetrician, you’d never guess that at the time his father was an engineer and his mother an L.S.U. doctoral candidate in nuclear physics. Sanford’s first political ad in 2002 told of how growing up on his “family’s farm” taught him “about hard work and responsibility.” That “farm,” the Charlotte Observer reported, was a historic plantation appraised at $1.5 million in the early 1980s. From that hardscrabble background, he struggled on to an internship at Goldman Sachs...
Really, it's too much!

Thank you Party of Limbaugh! You sure know how to make me forget my minor woes ...

Economist obituary: Christopher Nolan

The photograph accompanying Christopher Nelson's obituary shows a young Nolan with his mother by his side, his father smiling in the background.

I wonder how the heck they got that photograph.

Nolan asphyxiated when eating, a complication of his severe cerebral palsy.

The Economist tells the story of an author and poet with a terrible disability and remarkable parents (and, I suspect, friends and family too). The obituary doesn't mention that he inspired a U2 song.

It's a memorable story, remarkably written. The Economist saves its best writing for the last page, and some nameless wordsmith wrote their heart out to get this one done.

Economic recovery test -- the pencil sharpener

I've recently proposed the toaster test as a measure of economic recovery. We'll know the economy is healthy when it's again to buy a toaster that works well for ten years.

Personally I like the toaster test, but it takes a lot of toast to show that the toaster works. Not everyone likes toast as much as I do. Fortunately there's a cheaper alternative, one that I mentioned in a rant last year...
... This morning our last modern pencil sharpener broke. We have only one that works now. It's twelve years old, I remember coming across it in the campus bookstore ... It was made in Germany. We're going to mention it in our will, it may be worth a fortune thirty years from now...

... How to explain this emergent conspiracy of globalized incompetence and occult inflation? Clearly the answer is related to Krugman and Hilton [1] and the reelection of George Bush... Consumers are ... consistently making very poor choices, and the market is responding to the frailty of the consumer...
When we buy pencil sharpeners now they look like this:



When we can buy pencil sharpeners that work as well as this one ...



the economy will be on the mend.

The iChat abandonware problem - a sign Apple is in trouble

There's a feature in iChat, Apple's videoconferencing software, that's supposed to allow users to auto-accept chats.

It looked promising for what I want to do -- set my mother up for videoconferencing in the simplest possible way.

Problem is, when you activate it, you get this message:
AppleScript Event Handler Error
... Event: When I Log In
File: Auto Accept.applescript
Error: Error -1708
It's not a new bug, it was recognized at least two years ago. Apple hasn't fixed it in 10.5.6.

It's not the only sign that iChat is abandonware.

Apple didn't used to be this bad. My recollection was that with 10.3 they tried to fix egregious bugs and they incrementally improved their bundled apps.

Something changed after 10.3. Maybe it was losing Avie Tevanian, or maybe it was when Apple decided that they would stop adding significant new features with OS point releases, possibly related to their interpretation of Sarbanes-Oxley revenue recognition (aka technical accounting) ...
Gordon's Notes: Sarbanes-Oxley means no features in future software updates from publicly traded companies?

... Update 3/10/07: I'd read some coverage that claimed Apple was interpreting Sarbanes-Oxley incorrectly. I'd written our representative to ask about this, and Betty McCollum's office replied "Apple has to account for the separate value of a software upgrade that allows for additional capabilities from the hardware.... a nominal fee ... establishes a reportable value for the upgrade." So Apple has interpreted the law as congress understands it. At least when it comes to enabling new hardware capabilities, SO means Apple must account for the value delivered. A nominal fee is one way to do that.
Of course here we're talking bug fixes, not new features, but I wonder if there's an indirect connection.

I see similar problems across OS X applications, such as iCal, Address Book, etc. They're pretty competitive when the OS is first released, but they're very buggy. After a point release or two the biggest bugs get more or less worked out, but then they slowly fall behind the competition.

Apple doesn't improve them, so over time they're less used. They become abandonware. Unfortunately, their bundled existence also prevents vendors from easily filling the gaps with aftermarket products.

Then a new OS release comes along and the cycle begins anew. Of course the new release often requires purchasing new hardware ...

This has become a kind of sickness for Apple. They desperately need better quality in their non-core OS applications, but they also need to find a way to stay competitive with these apps. They could change their interpretation of Sarbanes-Oxley, they could change the way they recognize revenue, or they could separate these core apps from the OS (the way they did with iLife -- some of those apps used to be bundled with the OS).

I'm not a representative Apple customer, so I can't say this sickness is all that harmful to them. I think though, if they wait for signs of retail trouble, that they'll find they've waited too long. Maybe Apple should consider customers like me to be the "canary in the coal mine".

This canary is looking for a new mine.
