My Best Teaching Is One-on-One

一対一が僕のベスト

Of course, I team teach and do special lessons, etc.

当然、先生方と共同レッスンも、特別レッスンの指導もします。

But my best work in the classroom is after the lesson is over --
going one-on-one,
helping individual students with their assignments.

しかし、僕の一番意味あると思っている仕事は、講義が終わってから、
一対一と
個人的にその課題の勉強を応援することです。

It's kind of like with computer programs, walking the client through hands-on.
The job isn't really done until the customer is using the program.

まあ、コンピュータプログラムにすると、得意先の方に出来上がった製品を体験させるようなことと思います。
役に立たない製品はまだ製品になっていないと同様です。

Vector Multipliers

I guess I'm being too oblique.

My cousin just shared this on BassHook Facebook:

https://www.latimes.com/world-nation/story/2020-05-03/what-do-you-do-with-a-billion-taters-and-the-folks-who-grow-them?

(If you load it too many times, it'll throw up a paywall.)

Billions of potatoes, no place to put them.

What is missing from the picture?

Similar volumes of lettuce, cabbage, wheat, rice, corn, soybeans, ..., beef, chicken, ...

All of this food must be moved from the source to some sort of consumer, or they will spoil. (Yes, with our current methods of production, we are going to have to slaughter a lot of meat that will not be going to the usual markets.)

Spoil? Is that so bad? Lakes of vodka, whiskey, .... What can be bad about that?

If only the spoilage would be so tame.

Rats. Flies. Fleas.

Germs. Bacteria.

More virus.

How did this pandemic start?

Well, let's look at history for clues. Spanish flu? Going back even farther, the black death and the bubonic plague?

It's rather simple. (Yes, I'm repeating myself.) When you get too many people in one place without proper hygiene, with too much stress from overwork, in too close quarters with the cattle, various biologically active material brews up disease vectors. Then the vermin (Remember, everyone is too busy to be clean.) and cattle spread those vectors every direction they go.

Why do people live in such conditions? Because there's no room for them on the planet?

No, there is plenty of empty space on the planet, if we used it well. They are just too poor to go there, or their governments (or pseudo-governments) are too unwilling to let them go, or both.

But overpopulation!!!!!

... is also primarily a feature of large populations without sufficient material means, and many of the reasons for that are known.

And, as I say, overpopulation is more a problem of people in power being unwilling for the poor to go away, because they depend on the population of the poor to prop up their illusions of power.

We live in one of the most materially productive periods in history.

How productive are we?

Even without the problems of having no market to sell potatoes and other products, we, as a planetary society, dispose of enough product to feed all the poor people on the planet, and then some.

If I have not mistaken the math, even with about half our total population not being directly involved in producing the basic material necessities of food, clothing, shelter, and medicine, we are productive enough to feed, clothe, shelter, and medicate twice the current population, if we were only effective at distributing it all.

In spite of that level of productive, our leaders in the industries are still engaging us in a race to the bottom, still trying to raise production levels so that they can compete for even more power (as they imagine it).

If you think that your politics is clean from this, look again. Democrats, Republicans, Liberals, Conservatives, Libertarians, Communists, Socialists, everybody is in on it.

Why? politics requires power. Power requires profit. Profit is most easily generated in a hurry by a race to the bottom.

I commented earlier that the universal pseudo-quarantine had some good side effects, in terms of giving families time to get acquainted with one another again. It was a good thing, for a week -- or even a month. We could have recovered from it at that level.

Now farmers, who can least afford it, are paying from their own pockets to move the potatoes, not to the usual markets, but to anyone who will claim them. This is actually not a bad thing, if the lenders come to their senses and accept responsibility for creating the situation that requires this in the first place -- if they will simply accept the right and proper financial burden of their own fixation on hyper-competition.

How can we prevent the coming pandemic aftershocks? How can we stop the death toll at the current projection of 350,000?

Let's be serious.

The current supply chains are rather pathological. They rely on unbalance and excessive consumerism.

We are the most productive this planet has ever seen, but a huge piece of our production is wasted moving product halfway around the world. (Or farther. We are really, really inefficient.)

We are the most productive this planet has ever seen, but well more than half of us are suffering from lack of material necessities and, at the same time, suffering from overwork.

We are destroying enough product to provide for everyone on the planet, and yet we are still trying to find ways to work harder.

And we are squelching the planet's ability to be productive. See the lakes drying up, etc.

What is wrong with this picture?

Could we provide enough if we depended more on local production?

Would the current pandemic have spread so much if we weren't ordering things from all over the globe?

My current job is delivering things. If I have a symptom-less case of the 2019 version Coronavirus, I'm going to bring something like a hundred households a day into contact with the infection vectors.

After the first week, the universal pseudo-quarantine has actually been magnifying the epidemic.

Does this mean we should have lots of raves?

Does this mean we should give up the sudden shift to education methods that are more home-centered with on-line support and reporting?

Does this mean we should go back to sixty-hour work weeks? Or even forty, when twenty will do plenty?

Twenty hour work weeks would give us time to learn the things that will help us avoid the next pandemic, you know. From history.

Twenty hour work weeks would also give us time to learn about the traditions we have received from our ancestors, and honor our ancestors by learning to keep the good traditions and discard the bad ones.

Twenty hour work weeks would put less pressure on us to try to force ourselves and our families to conform to meaningless norms.

Twenty hour work weeks would give us time to work on the supposedly non-profitable problems, like reducing the negative ecological impact of our economic activities.

In the immediate cause, twenty hour work weeks would give us time to help farmers move excessive potatoes from the places where they are going to cause problems to places where they can be usefully and meaningfully consumed.

And twenty hour work-weeks would give us time to learn how to take care of the basics of nutrition and hygiene, the lack of which is one of the reasons the virus spreads so easily in the first place.

Twenty hour work weeks would give us more time to make life meaningful, and would still leave us producing enough for other people's needs.

How could this be done?

Speaking in the ideal, Bill Gates is easy to pick on. I'm not going to enumerate his sins here, but he clearly made excessive profits on his ephemeral products. He should not be "donating" hundreds of millions to charities (mostly profitable to himself). He should not have that money, period. And he should have gotten himself out of the way long ago, so more talented men of better vision than he could have advanced the information industry much, much farther along than it is today.

But Bill Gates is only one very prominent among many.

No one is justified in amassing more than enough to retire five times over. When you have that much, you should boot yourself out of the industry you made your money in and devote the rest of your life to service without remuneration.

That would leave men of better vision than you (because they are not buffered from their lacks by excessive money) to take the lead.

[JMR202007121717:

(I've failed to repeat the conclusion. Perhaps I thought it would be obvious enough if I just said it once.)

If those who have amassed such fortunes weren't sitting on their fortunes and driving the race to the bottom, ordinary individuals could be paid more to work less.

Now, some people think that paying people more to work less is some sort of sin.

But when it means people don't have to destroy their own health to keep food on their families' tables, it is most definitely not a sin. Or a crime.

When people can take care of their families' needs without destroying their own health, most of the paths that disease vectors follow in turning into epidemics are naturally closed off, and the remainder can be more easily closed off without disrupting external society -- without disrupting business.

Masks, Protection, Courtesy, and the Virus

I learned the custom of masks here in Japan about 40 years ago, back when it was definitely an unfamiliar sight outside Japan, and when many fellow 外人 (gaijin)  here made fun of the practice.

The first guy who explained it to me was my trainer as a missionary. As most missionaries are, he was not perfect, but his explanation was later confirmed by Japanese people I trust. This was not one of the things he misunderstood.
The mask is a custom of courtesy, less to protect the wearer than to provide partial protection for the people around him or her.
(I mention the fact of his misunderstandings because it is a fact of life, as a stranger in a strange land, that one must assume that information is, at best, incomplete, and often wrong. I guess it's even more of a fact of life when you think you are not a stranger.)

I am not an expert. I know what I'm talking about, but there are many things I don't know. Nonetheless, I think many people are operating without even this much knowledge about masks.

One, they are not, by any means, perfect protection.

Even the best masks, the ones used in surgery when the patient is immuno-compromised, are not much use long-term. Just as needles should never be re-used, the masks worn in surgery should be disposed of after finishing the surgery (and sometimes replaced periodically even during a single surgery).

[JMR202005261910 added:
I had a surgical nurse tell me I'm wrong about the above. I guess she wasn't in the operating room where I was operated on. Not every operation requires the same level of protection. But she does acknowledge washing her mask daily.
]

Why? Spattered blood or other body fluids quickly soak through the mask. Likewise, moisture, spit, phlegm, etc. from the breath of the person wearing the mask soaks through the other direction.

Faces itch under the mask, and the mask slips, so the mask tends to be touched by either the wearer's hands or an assistant's hands. This offers opportunity for transferring biologically active matter both ways across the barrier.

(Biologically active matter -- virus particles, bacteria, infected body cells, etc.)

Ordinary masks are much more porous than surgical masks, and the wearers tend not to replace them every fifteen minutes to half-an-hour. (That would be rather difficult, really, both economically and logistically -- and ecologically, come to think of it.)

[JMR202005261925 added:
I know I'm speaking in extremes in the above. The point I'm trying to make is that masks are not magic shields that block all the bad stuff and let the good stuff through no matter how long you wear them. Don't go to a rave wearing a mask and expect the mask to protect you.
]

Using terminology from information security, masks are a low wall or a speed bump.

Like the low wall and the speed bump, they can actually make problems worse when we refuse to use sense when we use them.

So why wear them at all, other than wearing true surgical masks in surgery?

[JMR202005262020 added:
Someone might bring Japan's infection and fatality rates up as empirical evidence. Yes, it is evidence, but you should understand that Japan has a long tradition with masks and other habits than help to limit the spread of aerosol spread diseases.

You do know about bowing instead of shaking hands, right? Well, even that is not that simple, but it's there. You aren't getting the whole story about Japan in the news.

Japanese people have been effectively voluntarily limiting a lot of the more dangerous activities.

Yes, there was an order, but it had, in the western mode of expression, no teeth -- other than social pressure, which is pretty powerful in Japan. Many of the less necessary businesses have been shuttered for the last couple of months, and, while there were a couple of the "live events" that Japanese entertainers, artists, comedians, etc., sometimes hold in the days after the order, people came away infected, and that fact was heavily reported and made the topic of talk shows and comedians' acts. Serious social pressure not to hold any more.

Sumo and professional baseball put on hold. The national high school baseball tournament, which is as big as the Japan Series in the fall, canceled for this year. (Probably. It might get revived if things go well now the order has been lifted.)

Japan is a country of mixed-mid-to-high population density.  Masks tend to be used more commonly in population centers.

Close quarters requires building walls that don't make sense in less densely populated places.

Many of Japan's differences in customs have to do with common-sense differences between low-density environments and high-density environments.

Many of the common-sense customs have been altered against reason and sense over the last three-quarters of a century, and here is one. Wearing a mask and going to work is actually a self-contradictory behavior. If you need to wear a mask, you shouldn't be going to work, whether you are trying to protect yourself or your co-workers.

Well, unless your job is important.

(Ahem.) Unless your job is especially important, because every job is important. And unless your job is not so important that passing a common cold among your co-workers would be a bad thing.

Hmm. Maybe I'm getting sidetracked, doing a bit of hand-waving at topics this post doesn't have room to tackle. Back to the point.

Okay, so the traditional use of the mask was for cases where you were a wee-bit sick, but your need to be at work or to go to the market outweighed your need for rest and isolation. (And outweighed their need for you to be getting rest and isolation.)

Wearing a mask every day, long term, was neurotic behavior, but your friends would put up with it because they had their times of paranoia and neurosis, as well.

And, here's the kicker: Even though the mask can be counter-effective if you misuse it, for such things as the common cold, the speed-bump has regularly helped slow the spread until everybody developed resistance. This is repeating in the current case.

What kinds of behavior are counter-effective?

Counter-effective mask behaviors include such things as when you fail to wash your washable mask at least once a day, or dispose of your disposable mask in an appropriate garbage pail. Or regularly take it off and set it down where it can aid in the spread of germs.

Or such as wearing a mask so you can go out when you're coughing up so much that it gets soaked by your phlegm before you get home. Or decide that, because you are wearing the mask you don't need to wash your hands or stay home from work or stay away from public places like the market.

[JMR202005262040 added:
And there is also the recent news from China about a couple of students who were made to wear masks while they were given exercise tests, who died from respiratory/circulatory failure which was likely induced by the high-filtration masks. Wearing a mask with excessive filtration is another mistake.
]

(Masks can be good while you're sleeping, to keep the throat and sinuses moist -- until the mask slips down, anyway, and if they aren't too tight to let you sleep. And if you aren't reacting to the inevitable lint. In this particular use, it's good to get the mask wet before you go to bed.)

For the individual, wearing a mask probably does not stop you from getting infected. It does slow the infection process down enough that your body can often fight it off, or you can get by with just catching a mild case.

(In surgery, if a doctor has symptoms, he or she is going to postpone the surgery or get someone else to do it, instead of depending on even surgical masks, etc.)
[JMR202005262045 added:
Related information, one medical study estimates that the rate of asymptomatic infection of SARS-CoV-2 in Kobe is probably 3%.
]

In groups (in the calculus of social behavior), having many speed-bumps and low walls helps slow the rate of spread down enough to prevent an epidemic. (Or slow down an epidemic to prevent it becoming a pandemic.)

If people behave sensibly.

If and only if people behave sensibly in the aggregate.

Aside from such things as cancelling raves and other high-attendance, close-encounter activities, what kinds of behavior are the common-sense behaviors I'm talking about?
Well, I've posted twice on this, if you want some more light reading:
[JMR2020052055 added:
For what it's worth, I wear a mask when I'm out working. (I'm currently working as a long-term temporary postal delivery person for Japan Post.) It is required for the job, but I do not wear it because of the requirement, and I do not wear it because of social pressure.

I wear it for courtesy.

I recommend wearing masks for the duration, in general. I do not recommend trying to force everyone to wear them. Too many people have problems with masks that they are unable to express or explain.

If masks cause you problems, I recommend restricting your close-quarters contacts as much as you can.
]

In summary, masks are an example of the fact that individual behavior does matter, and that being courteous does come back to you.
