Calvinist theology: from Garrison Keillor

Much has been made of Bush's neo-Calvinism, but this summary of Calvinist doctrine is new to me...

The chosen president | Garrison Keilor

...Calvinism, as all of you Calvinists know, is based on five points of doctrine, which spell out the word 'TULIP' -- total depravity (everybody is sinful), unconditional election (God chooses who'll be saved, it's not up to you), limited atonement (Jesus didn't die for everybody, just for the chosen), irresistible grace (if God chooses you, you're saved, you can't resist) and perseverance of the saints (once saved, always saved, no matter what you do).

I didn't know about the L and the P. What a merciless, cruel faith. That's a God to fear ...

Myelin disorders underlie schizophrenia?

White Matter Matters in Schizophrenia: Scientific American

Scientists have suspected for more than two decades that schizophrenia is linked to defects in the brain's white matter. They could not tell, however, whether changes in the information-transmitting region of the brain detected by brain scans or autopsies were the cause or the symptoms of the illness.

A new study not only clarifies the association but also links it to genes previously tied to the debilitating mental disorder and chemical changes believed to occur in the schizophrenic brain. "[The report] provides evidence that alterations in myelin [the lipid layers that sheath and insulate nerve fibers and are the main constituent of white matter] can cause defects in neurons and the central nervous system in general that are related to neuropsychiatric disease," says the study's senior author Gabriel Corfas, a professor of neurology at Harvard Medical School's Children's Hospital Boston.

Corfas's team studied mice in which they blocked the erbB4 receptor, in oligodendrocytes, which make up the myelin sheath over a neuron's communication hub. The erbB4 receptors receive a growth factor called neuregulin 1, which is necessary for proper brain development. Genes expressed in oligodendrocytes—such as the one that codes for neuregulin 1—have previously been linked to schizophrenia, bipolar disorder, depression and obsessive-compulsive disorder....

...Corfas says that the new findings indicate that screening children with noticeable cognitive and social defects for increased white matter or changes in its organization could lead to earlier diagnosis of schizophrenia. In addition, he says the results indicate that therapies designed to treat other white matter disorders such as multiple sclerosis could be useful in treating schizophrenia and other neuropsychiatric disorders.

Since there are animal models for schizophrenia I'm sure the researchers have already tested drugs developed to enhance myelin production and preservation. Those papers should be out shortly ...

Now aiming SETI dishes at Gliese 581

How do you pronounce Gliese anyway? We need a better name than Gliese 581 for this large rocky planet in a "temperate" orbit around a smaller, colder, Sun:

BBC NEWS | Science/Nature | New 'super-Earth' found in space

... The Gliese 581 super-Earth is in what scientists call the 'Goldilocks Zone' where temperatures 'are just right' for life to have a chance to exist.

Commenting on the discovery, Alison Boyle, the curator of astronomy at London's Science Museum, said: 'Of all the planets we've found around other stars, this is the one that looks as though it might have the right ingredients for life.

'It's 20 light-years away and so we won't be going there anytime soon, but with new kinds of propulsion technology that could change in the future. And obviously we'll be training some powerful telescopes on it to see what we can see,' ...

Twenty light years? Might as well be next door. I trust the radio dishes will try to sneak a listen. It's unlikely that we'll pick up any television, but it never hurts to listen :-).

I wonder how old the sun of Gliese 581 is.... I'll pronounce it Gleesee for now ...

Update: Much more information here ... I thought I was being facetious about the SETI dish. Emphases mine. Note the star is Gliese 581, the planet, for now, is Gliese 581c.

... The star at the centre - Gliese 581 - is small and dim, only about a third the size of our Sun and about 50 times cooler.

The two other planets are huge, Neptune-sized worlds called Gliese 581b and d (there is no "a", to avoid confusion with the star itself).

The Earth-like planet orbits its sun at a distance of only six million miles or so (our Sun is 93 million miles away), traveling so fast that its "year" only lasts 13 of our days...

... Just because Gliese 581c is habitable does not mean that it is inhabited, but we do know its sun is an ancient star - in fact, it is one of the oldest stars in the galaxy, and extremely stable. If there is life, it has had many billions of years to evolve.

This makes this planet a prime target in the search for life. According to Seth Shostak, of the Search for Extraterrestrial Intelligence Institute in California, the Gliese system is now a prime target for a radio search. 'We had actually looked at this system before but only for a few minutes. We heard nothing, but now we must look again.'

By 2020 at least one space telescope should be in orbit, with the capability of detecting signs of life on planets orbiting nearby stars. If oxygen or methane (tell-tale biological gases) are found in Gliese 581c's atmosphere, this would be good circumstantial evidence for life.

... The real importance is not so much the discovery of this planet itself, but the fact that it shows that Earth-like planets are probably extremely common in the Universe.

There are 200 billion stars in our galaxy alone and many astronomers believe most of these stars have planets.

The fact that almost as soon as we have built a telescope capable of detecting small, earth-like worlds, one turns up right on our cosmic doorstep, shows that statistically, there are probably billions of earths out there.

... Interestingly, Gliese 581c is so close to the Earth that if its putative inhabitants only had our level of technology, they could - just about - pick up some of our radio signals, such as the most powerful military transmitters. Quite what would happen if we for our part did receive a signal is unclear...

This type of discovery further reduces the degrees of freedom in the Drake Equation, pushing the resolution of the Fermi Paradox further towards the "go no more a roaming" answer.

The SETI home page has an article on M Class suns, which I think includes Gliese 581.

...M-Stars, are of interest simply because there are so many of them—they are the most common star in the galaxy. They’re the cool stars that inhabit our neighborhood...

... There’s considerable interest in the question of whether M-Stars could host habitable planets. Would the planets be tidally locked with one face always directed toward the M-Star? Would flares wipe out life on the local planet? If M-Stars could host habitable planets, life may be much more widespread that we’ve previously thought...

...Dr. Peter Backus, Observing Programs Manager for SETI, concluded in a preliminary report on the M-Stars workshop, “One…aspect of M dwarfs makes them intriguing for SETI: they may be ideal hosts for advanced technological civilizations because they live an extraordinarily long time. Stars like the Sun live (i.e., they fuse hydrogen into helium) for only about 10 billion years. No M dwarf that ever formed has yet to die; no M dwarf will die for more than another 100 billion years. With such long lifetimes, there are big possibilities for these small stars.”

Update: Much more here, in a blog dedicated to this topic.

Index funds: whether you're a behaviorist or an efficent marketeer

I used to wonder if index funds would still work if everyone signed up for them. Presumably not, but there seems little risk of that.

But do index funds work if behaviorists are right and the markets are not rational? DeLong summarizes a very readable Justin Fox discussion of the topic. Supposedly index funds still work. Now about those Hedge Funds?

Masters of the Virtual World: Billion dollar hedge fund managers and the equity price premium

MR reviews the news on hedge fund manager earnings:

Marginal Revolution: Jordan fact of the day:

..."The combined earnings of the world's top 25 hedge fund managers of more than $14bn ... exceeded the national income of Jordan last year and three individuals took home more than $1bn, according to the biggest annual industry survey...

... What we see are the fearless super-rich having the resources and the liquidity to bid away the equity price premium, plus grab extra profits on the side...

MR has some important links, including to a NYT article Emphases mine:

... The earnings of these masters of the new universe — Mr. Simons took $1.7 billion — dwarfs the $54.3 million that Goldman Sachs chief executive Lloyd C. Blankfein earned last year, a sum that itself sparked controversy among industry watchers, including DealBook readers.

Some view these handsomely rewarded managers as this generation’s robber barons, using wealth to create wealth, often in secretive ways, and leaving little that is tangible in their wake.

“There is some question as to what the hell they are doing that is worth” that kind of money, J. Bradford DeLong, an economist at the University of California, Berkeley, told the Times. “The answer is damned mysterious.”

Others look upon them as new-economy financiers, evoking the likes of John D. Rockefeller or John Pierpont Morgan as they provide liquidity to the markets and broadly diversify risks in the banking and financial systems.

“You had railroads in the 19th century, which led to the opening up of the steel industry and huge fortunes being made,” Stephen Brown, a professor at the Stern School of Business of New York University, told the Times. “Now we’re seeing changes in financial technology leading to new fortunes being made and new dynasties created.”

... Combined, the top 25 hedge fund managers last year earned $14 billion — enough to pay New York City’s 80,000 public school teachers for nearly three years, the Times said....

... Mr. Simons, for example, has some of the highest fees in the business — 5 percent of assets under management and 44 percent of profits. But the Times notes that he trounces most of his competitors year after year: In 2006, the $6 billion Medallion fund posted gross returns of 84 percent; 44 percent after fees, explaining his $1.7 billion take.

“If you pay peanuts, you get monkeys,” said Jim Dunn, a managing director with Wilshire Associates, an investment advisory firm. “We don’t concern ourselves with fees. If you can provide Alpha, I’m less concerned about what you bring home.” (Alpha is producing returns that are not tied to a market benchmark like the Standard & Poor’s 500-stock index.)

Lord, words like "we don't concerns ourselves with costs" sound very bubbly to me. My knowledge-free bet, based solely on observing how humans work, is that MR is right that the "equity premium" (the reason that stock markets have historically been a better investment than loaning money directly) is overly large in Economy 3.0, and Simons and his kin are winning the prize for sucking it down. Once it's down, however, it has nowhere to go, and the money will run dry. Also based on how humans work, I bet the "legitimate" efficiency work was finished over a year ago, and the prizes now are financial bubbles flowing into the pockets of the luck-favored prepared mind. Naturally the winners, Masters of the (virtual) Universe, assume they are deities and the prize reflects their superhuman worth. Tears are likely to lie ahead ...

Billions. Sloshing around. Wouldn't you like to be there to catch the spills?

In the meantime, if one assumes the risk premium has been over-deflated, it is likely that investors in today's market are being under-rewarded for the risks they are bearing. Which means, given the recent rise in the market, that the risk is rather substantial.

The virtual fuses with the physical: Google Blueprint

The AIA is the professional organization of American architects:

Official Google Blog: New 3-D layers from AIA on Google Earth

... fly to America’s Favorite Architecture, a layer featuring the American public’s favorite architecture (as selected though a national poll announced earlier this year). View all 150 structures, including many with just created 3-D models of the buildings, ballparks, bridges, and memorials that characterize architecture in the eyes of Americans. And then explore the second layer, Blueprint for America. Blueprint is a community service effort funded by the AIA, in which AIA members donating their time and expertise are collaborating with community leaders and local citizens to enhance the quality of life in their community. You’ll be able to track the progress of these projects on Google Earth as they unfold over the next year and, we hope, become inspired to take action where you live.

As an exercise, contemplate a similar virtual/physical interaction with public health. What other examples of how the physical and the virtual may meet, particularly when organizational entities (themselves virtual and physical) are involved?

And so the world quietly, and invisibly, morphs into something quite different from the world my parents have known.

We'll prevent Alzheimer's before we prevent obesity: lessons of The Pill

There are, I heard on NPR, about 9 promising Alzheimer's prevention therapies in trial [1]. It's likely that, sometime in the next decade, one of them will be a mega-blockbuster -- the biggest change in medical care since the discovery of insulin.

On the other hand, I doubt we'll see a great obesity prevention therapy, despite the billions pharmas are investing into obesity research.

Why is one relatively easy, and the other so hard? Why is it so hard to come up with a safe and effective male contraceptive, but so easy to render women infertile? The Pill (oral contraceptive pill, aka OCP), after all, made its debut over 40 years ago.

The trick is whether one is fighting nature, or not. Women in pre-industrial societies are naturally infertile for most their reproductive years. They're either pregnant, lactating, or cyclically infertile. These are natural states, OCPs need only send "pregnant-lactating" signals and the body does the rest. On the other hand there is no natural state of male infertility. When you try to render a male infertile, you are fighting hundreds of millions of years of evolution.

Obesity is what happens when a biological system engineered to manage scarcity runs into an environment of abundance. The system crashes. Humans did not evolve to have access to so many calories all the time, like all animals we're engineered to use energy as efficiently as possible. Changing that means defeating evolution.

Cancer appears to be a process that natural selection has carefully tuned to balance biological repair mechanisms. It's darned hard to fight cancer.

Alzheimer's though, is a universal lifelong proces that disables the aged post-fertile human. It does not appear to have any significant evolutionary advantage, it is probably the end-result of a garbage collection process that works well within its operational "design" parameters. To delay the Alzheimer's process doesn't require defeating natural selection, so it's a much easier task that defeating obesity.

So I'm betting on an Alzheimer's preventive therapy long before a really good obesity preventive therapy.

[1] Note prevention and cure are different. There's not much prospect yet for curing Alzheimer's, though one might hope a good preventive therapy might allow natural reparative functions to operate better.

American food for people and pets: an industry insider speaks out

The author of this WaPo article was "president of NutraSweet Kelco Co. from 1994 to 1997. He is a management consultant to many large food ingredient companies." In other words, an insider with both biases and credibility. Emphases mine:

Peter Kovacs - It's Not Just Pet Food - washingtonpost.com

Lost amid the anxiety surrounding the tainted U.S. pet food supply is this sobering reality: It's not just pet owners who should be worried. The uncontrolled distribution of low-quality imported food ingredients, mainly from China, poses a grave threat to public health worldwide.

Essential ingredients, such as vitamins used in many packaged foods, arrive at U.S. ports from China and, as recent news reports have underscored, are shipped without inspection to food and beverage distributors and manufacturers. Although they are used in relatively small quantities, these ingredients carry enormous risks for American consumers. One pound of tainted wheat gluten could, if undetected, contaminate as much as a thousand pounds of food.

Unlike imported beef, which is inspected at the point of processing by the U.S. Agriculture Department, few practical safeguards have been established to ensure the quality of food ingredients from China.

Often, U.S. officials don't know where or how such ingredients were produced. We know, however, that alarms have been raised about hygiene and labor standards at many Chinese manufacturing facilities. In China, municipal water used in the manufacturing process is often contaminated with heavy metals, pesticides and other chemicals. Food ingredient production is particularly susceptible to environmental contamination.

Equally worrisome, U.S. officials often lack the capability to trace foreign-produced food ingredients to their source of manufacture. In theory, the Bioterrorism Prevention Act of 2001 provides some measure of traceability. In practice, the act is ineffective and was not designed for this challenge. Its enforcement is also shrouded in secrecy by the Department of Homeland Security.

Even if Food and Drug Administration regulators wanted to crack down on products emanating from the riskiest foreign facilities, they couldn't, because they have no way of knowing which ingredients come from which plant. This is why officials have spent weeks searching for the original Chinese source of the contaminated wheat gluten that triggered the pet food crisis.

That it was pet food that got tainted -- and that relatively few pets were harmed -- is pure happenstance. Earlier this spring, Europe narrowly averted disaster when a batch of vitamin A from China was found to be contaminated with Enterobacter sakazakii, which has been proved to cause infant deaths. Thankfully, the defective vitamin A had not yet been incorporated into infant formula. Next time we may not be so fortunate.

Currently, most of the world's vitamins are manufactured in China. Unable to compete, the last U.S. plant making vitamin C closed a year ago. One of Europe's largest citric acid plants shut last winter, and only one vitamin C manufacturer operates in the West. Given China's cheap labor, artificially low prices and the unfair competitive climate it has foisted on the industry, few Western producers of food ingredients can survive much longer.

Western companies have had to invest heavily in Chinese facilities. These Western-owned plants follow strict standards and are generally better managed than their locally owned counterparts. Nevertheless, 80 percent of the world's vitamin C is now manufactured in China -- much of it unregulated and some of it of questionable quality.

Europe is ahead of the United States in seeking greater accountability and traceability in food safety and importation. But even the European Union's "rapid alert system" is imperfect. Additional action is required if the continent is to avoid catastrophes.

To protect consumers here, we must revise our regulatory approaches. The first option is to institute regulations, based on the European model, to ensure that all food ingredients are thoroughly traceable. We should impose strict liability on manufacturers that fail to enforce traceability standards.

A draconian alternative is to mount a program modeled on USDA beef inspection for all food ingredients coming into the country. This regimen would require a significant commitment of resources and intensive training for hundreds of inspectors.

Food safety is a bipartisan issue: Congress and the administration must work together and move aggressively to devise stricter standards. Rep. Henry Waxman (D-Calif.), chairman of the House Government Reform Committee, has deplored dangerous levels of lead in vitamin products originating in China. We must get to the bottom of this pressing public health issue, without self-defeating finger-pointing.

The United States is sitting on powder keg with uncontrolled importation and the distribution of low-quality food ingredients. Before it explodes -- putting more animals and people at risk -- corrective steps must be taken.

Regulatory standards are a very tempting way to create de facto "protection" for selected industries. The protectionist impulse can do great economic damage, and the profits associated with such de facto tariffs are a rich source of political corruption in America. Alas, there may be no alternative. We don't have a proven market solution to this kind of risk, and our present failure makes action unavoidable. We will need new regulations for human food.

As for pet food - as I wrote earlier - there's a simple quasi-Libertarian solution. Pet food manufacturers should formulate a product for human consumption derived from the same sources as the animal product. This premium product would therefore fall under FDA regulation. The CEO and board would eat at their regular meetings, and major suppliers would be also be sent snacks. Selected pet owners who are also ambitious lawyers would add it a few snacks to their diet every few months. If a problem were then discovered, the legal onslaught would be brutal, effective, and highly profitable for the lawyers involved. Food that carried the "We eat our own dog food" slogan would sell for a premium price of course. A major US accounting firm would be engaged to manage the certification process, and to ensure that the CEO was dining properly.

Nasty, brutal, short - the life of most humans

I recently wrote of 19th century American aspirations for a 50 year lifespan. John Hawks describes other settings when life expectancy was about 35 ...

John Hawks Anthropology Weblog : 2007 03

Kim Hill and colleagues (2007) report in the current Journal of Human Evolution on the mortality profile of recent Hiwi hunter-gatherers. Here is their abstract:

"To our knowledge, interview-based life tables for recent hunter-gatherers are published for only four societies (Ache, Agta, Hadza, and Ju/'hoansi). Here, we present mortality data for a fifth group, the Hiwi hunter-gatherers of Venezuela. The results show comparatively high death rates among the Hiwi and highlight differences in mortality rates among hunter-gatherer societies. The high levels of conspecific violence and adult mortality in the Hiwi may better represent Paleolithic human demographics than do the lower, disease-based death rates reported in the most frequently cited forager studies."

...Among pre-1960 Hiwi males, 57 percent could expect to survive to age 15, and 43 percent to age 30, with an average young adult mortality rate of around 2 percent annually. So it is not anything like as high as has been suggested for Neandertals and earlier humans (with annual mortality rates as high as 6 percent).

The most interesting aspects of the paper are the comparisons between the Hiwi and other ethnographically-known hunter-gatherers. Many of the differences in mortality profiles are attributable to strong cultural differences:

"Cause of death among the groups differs considerably. Disease is an important cause of death in all groups, but represents only 20% of deaths in the precontact Ache, 45% among the precontact Hiwi, and about 75-85% of all Hadza, !Kung, and Agta deaths. Respiratory disease is the main killer of the Ache, whereas gastrointestinal pathogens are most important among the Hiwi and probably Hadza. Among the !Kung, respiratory and gut infections are about equally important. Violence is the major cause of death among the precontact Ache (55% of all deaths) and very important among the Hiwi (30% of all deaths), but notably less important in the two African societies and the Agta (3-7% of all deaths). Indeed, the crude homicide/warfare death rates per year lived are more than ten times higher among the Hiwi and Ache than among the Hadza or !Kung (1/100 and 1/200 per year for precontact Hiwi and Ache, respectively, vs. 1/2500 and 1/3000 for the Hadza and !Kung, respectively)..."

"If high mortality, warfare, homicide, and accidental trauma are typical of our Paleolithic ancestors, the Hiwi mortality patterns may be more representative of the past than those derived from other modern hunter-gatherers. If so, several observations about the Hiwi are important. First, conspecific violence was a prominent part of the demographic profile, accounting for many deaths in all age and sex categories. Most of the adult killings were due to either competition over women, reprisals by jealous husbands (on both their wives and their wives' lovers), or reprisals for past killings. The criollo-caused killings were motivated by territorial conquest. Moreover, infanticide (especially on females) constituted the highest mortality rate component of all Hiwi conspecific violence. Second, no predation deaths were reported despite attacks by anacondas, Orinoco caimans, and piranhas, and the presence of jaguars in the area. Accidents associated with the active-forager lifestyle were common, but disease was a more important killer, accounting for nearly half of all deaths. This suggests an adaptive landscape in which success in social relations, competitive violence, and disease resistance are paramount. This may partially explain why many of the genes that appear to have been under strong selection in the past 50,000 years affect either disease resistance or cognitive function (Wang et al., 2006), presumably related to success in an atmosphere of frequent violent social competition (Hill et al. 2007:451)."

These communities vary greatly in their level of violence. The most violent of them sound comparable to chimpanzees. The big surprise is how dominant these pre-technological human predators are. They died of disease or from conspecific violence or from accidents, not from other predators.

Nutro products: how NOT to do a pet food recall

Our dog's primary foods were not involved in the melanine recall (so far), but the company that makes some snacks we use had recalled gluten products. So one might think Nutro Products would be very careful about their statements on the rice recall.

Alas, their rice recall page simply says their rice containing products aren't derived from the known contaminated sources. As always, the unsaid words are important. They don't tell us that the products do not contain Chinese manufactured rice protein.

So we should assume they Nutro Food snacks do contain Chinese manufactured rice protein, we should assume that source is unreliable until proven reliable, and we should assume Nutro Products is being a bit dishonest about the risks of their foods. I've tossed this company's products, and we'll avoid them in the future.

I wonder if anyone will keep a global list ranking the quality of vendor responses to the melanine affair. It would be a handy reference to guide future buying decisions. If you know of such a list, send a note to jfaughnan@spamcop.net and I'll link to it.

Calendar curses: remembering Palm

I'm working on our family's week schedule, and again I weakly curse the state of 21st century calendaring. I have a work calendar on Outlook, a personal calendar on my Palm, and a variety of paper based family calendars. It's a mess and there's no solution on the market.

Which brings back a memory of a product that was briefly on the market, but which I can't locate on Google.

Back in the 90s, before they decapitated themselves and were simultaneously disemboweled by Microsoft, Palm was very focused on solving this type of problem. They introduced, or almost introduced, a home device that basically a "Palm server". It would hold the family calendar, and every family member would sync to it. I think it was supposed to be a "thin client" for email and kitchen web browsing as well.

Am I imagining this product, or did it ever come to market? It was near the end-time for Palm as a meaningful platform.

For now, I merely await the iPhone. I'm not overly optimistic, Apple's .Mac screw-up strongly suggests they've decided this problem is too hard to tackle.

The missing WMDs - only one man knows the truth

The latest mass delusion to strike the demoralized drones of American neoconservatism is that Iraq had oodles of WMDs that were spirited away by Russia and Syrian. The truth was then hidden in a Bush/Democrat conspiracy until a whacko British journalist found Dave Gaubatz, a civilian agent who worked for The U.S. Air Force's Office of Special Investigations. Gaubatz, it turns out, is the only man who will tell the real story.

Salon provides the gory details: Right-wing blogs discover massive conspiracy to hide WMDs in Iraq and suggests a visit to Gaubatz's web site. You'll have to find the URL on your own, but here's the first quote I found:

National Existence is political order experienced by men of the nation as a Rise to Being. Its opposite is a replacement of political order experienced by men, women, children and slaves as a Fall from Being. This Redirection in the experience of the Terms of Being (Self, Society, G-d and World) results in the collapse of Self into Society and all into World. The goal, wittingly or otherwise: a World State.

SANE opposes this Redirection and its manifestations: chants of Racism, Democracy, Equal Rights, Human Rights, Women's Rights, Animal Rights, and the always growing list of what is the Single Concept: Certainty/Uncertainty = Science/Open Society = World. To understand this reciprocal and how it affects a convergence of factors bent on the destruction of National Existence is to be SANE...

Gaubatz's other hobby, per quotes on unqualified offerings, is promoting the rightly privileged "distinct people" of "White Christians". UO also mentions "Dave Gaubatz was the 1st U.S. Civilian Federal Agent sent into Iraq at the start of Operation Iraqi Freedom in 2003". You could summarize the incompetency of the GOP and Bush administration with that single data point.

The American right has become a recursive engine of self-satirization. They'd be easier to pity if they weren't so nasty.

4/21/07: I had to rework the post title, I'd posted with the default link title. It occurs to me that this may be the kernel of a whacko "far right" 9/11 conspiracy theory, the complement to the whacko "left" delusion that a martians blew up the WTC (or whoever it's supposed to have been). Perhaps the two will unite someday ...

South Korea apologizes, America puzzled

Soo Yun, an American Journalist who was a Fulbright scholar in South Korea last year, describes a national South Korean apology to an inattentive America. I imagine the American ambassador must on the one hand accept graciously, but on the other hand point out that no apology is expected. Most Americans are probably oblivious to South Korea's distress. Today Americans do not have as strong a sense of collective ethnic identity as South Koreans.

So, South Korea, it's ok if you want to apologize, but, on average, most Americans probably don't expect it.

South Korean "blood" mythology is unusually strong, but it is not qualitatively different from other nations. Japan has a similar belief, though probably it is less strong now than it was 30 years ago. China was likewise appalled when Fox news reported the assailant was a Chinese student, and massively relieved when he was found to be 'South Korean raised in America'.

More broadly, consider this tribal identity in the context of these examples:

1. Who, if anyone, should apologize for the annihilation of the Amerindian, or for American slavery? Why should they apologize? Who inherits guilt, and why? How do societies answers change over time?
   
   
2. When can Germany stop apologizing for the Holocaust? How many generations are required? Does Germany have any moral responsibility to keep the memory of the Holocaust alive? (I'd say yes to the last, because of a much stronger version of #3, but it's debatable.)
   
   
3. American soldiers, during the disastrous early days of the Korean war, killed South Korean civilians to speed their escape. (The US Military has recently confirmed this story after an internal investigation - very quietly.) Should anyone living today apologize? (I'd say yes, because there's clear institutional continuity in the US military, but it's a debatable point.)
   
   
4. A euro-American wins a Nobel. Should black Americans be proud? Euro-Americans? The winner's mother? Euros? What if it's a Chinese American?
   
   
5. Canada wins an Olympic medal in Hockey. Should Canadians be proud of their team? What if Montreal wins the Stanley Cup over the Mighty Ducks (ha!) and the teams are both Russian?
   
   
6. Most citizens of the Arab world appear to hate Israel and Jews. A significant number were, at one time, sympathetic to attacks on the WTC. (I suspect that number has shrunk as everyone realizes that a crazed America is not a good thing.) Should an Arab-American apologize for this? (I'd say no, but I bet some apologize anyway ...)
   
   
7. Should Idi Amin's parents have felt guilty for his crimes? What about his teachers?
   

South Korea is a bit extreme, but if we examine the responses to these questions I think we'd find the differences are quantitative, but not qualitative. All humans struggle with the distinction between individual, family, tribe, nation, and culture and the notion of responsibility. Except, of course, for those of us who dispense with the concept of responsibility ...

Pet poisons: FDA suspects deliberate contamination

The theory that Chinese manufacturers spiked food with melanine to increase its apparent nutritional value now has FDA support:

Spiking theorized in pet deaths | Chicago Tribune

... Stephen Sundlof, chief veterinarian for the Food and Drug Administration, said melamine, which has turned up in more than 100 brands of cat and dog food, may have been used to falsely boost the apparent nutritional content of rice protein.

'That's still a theory but it certainly seems to be a plausible one,' he said.

In other news deaths are increasing in South Africa and contaminated feed has been fed to pigs. So melanine has probably entered the human food chain in a few places in the US.

Meanwhile, the Chinese government is declining requests for FDA visits and at least one US pet food manufacturer has sworn off any future Chinese sources.

We're going ahead with plans to make our own pet food.

How would a pet food company get our confidence back? They'd apply for permission to sell food for human consumption. They wouldn't actually sell the food for humans, but that would bring them into full FDA scrutiny. Then they'd provide a human-oriented version of their product for snacks at board meetings. If a company did all of that, I might be inclined to trust them ...

Parental controls - not an Apple thing

I have to limit the kids access to Google Video. Limit, as in, eliminate. Alas, Apple's parental controls are mediocre in 10.4 (better, supposedly, in the now delayed 10.5). If you allow access to a domain in Safari, you allow access to all. Apple's Airport Extreme has NO parental controls, my ultra-cheap DSL router has more.

I wonder how old Jobs kids are ...
