This Rochester Review letters page cheered us both considerably tonight.  Mike Armstrong, brilliant computer guru at the University of Rochester Computing Center in our day, confesses to being overwhelmed by today's computing power.  His letter ("Something Doesn't Compute" in about the middle of the page) is worth reading as a peek into the field's ancient history; we joined the game in the days of the IBM 360/65.  But it was to the final paragraph that we could relate best:

But those were, to me, the good old days of wooden computers and iron programmers. When I left the Computing Center in 1980, I felt I knew the room-sized computer systems thoroughly, from the hardware to the operating systems and most of the application programs. Now I carry a small computer in my pocket that has more memory and more computing power than all of NASA’s computers when they put Neal [sic] Armstrong on the moon, and I have no idea how it works. And it also makes phone calls.

My husband likes me to be with him, to look over his shoulder, while he works.  I am exactly the opposite.  With a few exceptions—such as when I want someone to "hold my hand" through an unfamiliar or difficult procedure—I hate it when someone watches me work.  I fall apart.  I trip over my feet, my fingers, my words.  Simple tasks that I can do without thinking suddenly become nearly impossible.  I become incompetent even in my areas of expertise.

Why?  I never had a clue, until I read "The New Neuroscience of Choking" from the New Yorker of a couple of years ago.  (Yes, it has been on my To Blog list for that long.)

[C]hoking is actually triggered by a specific mental mistake: thinking too much. The sequence of events typically goes like this: When people get anxious about performing, they naturally become particularly self-conscious; they begin scrutinizing actions that are best performed on autopilot. The expert golfer, for instance, begins contemplating the details of his swing, making sure that the elbows are tucked and his weight is properly shifted. This kind of deliberation can be lethal for a performer.

[An analysis of golfers] has shown that novice putters hit better shots when they consciously reflect on their actions. By concentrating on their golf game, they can avoid beginner’s mistakes.

A little experience, however, changes everything. After golfers have learned how to putt—once they have memorized the necessary movements—analyzing the stroke is a dangerous waste of time. And this is why, when experienced golfers are forced to think about their swing mechanics, they shank the ball. “We bring expert golfers into our lab, and we tell them to pay attention to a particular part of their swing, and they just screw up,” [University of Chicago professor Sian] Beilock says. “When you are at a high level, your skills become somewhat automated. You don’t need to pay attention to every step in what you’re doing.”

Brain research suggests that a major culprit in this problem is loss aversion, "the well-documented psychological phenomenon that losses make us feel bad more than gains make us feel good."

[T]his is why the striatum, that bit of brain focussed on rewards, was going quiet. Instead of being excited by their future riches, the subjects were fretting over their possible failure. What’s more, the scientists demonstrated that the most loss-averse individuals showed the biggest drop-off in performance when the stakes were raised. In other words, the fear of failure was making them more likely to fail. They kept on losing because they hated losses.

There is something poignant about this deconstruction of choking. It suggests that the reason some performers fall apart on the back nine or at the free-throw line is because they care too much. They really want to win, and so they get unravelled by the pressure of the moment. The simple pleasures of the game have vanished; the fear of losing is what remains.

Indeed.

Thanks to my NEHGS newsletter, I can point to where my own observations are confirmed (and explained) in print.  The Summer 2014 edition of the Old Sturbridge Village Visitor reports on some historical myths, one of which is that everyone died young in the olden days. I get so frustrated when people attempt to explain something in the past by invoking, "because they only lived to be 40 years old."  Many of my ancestors lived into their 70's, 80's, and even 90's.  Here's the explanation:

While average life expectancy was shorter in 19th-century New England than it is today, many people then lived into old age, and some even lived beyond 100 years. The Bible says that expected lifespan 3,000 years ago was "70 years; 80 for those who are strong" (Psalm 90:10). But before the mid-20th century, people died regularly in all stages of life, not just in old age. Life expectancy at birth in early 19th-century New England was only in the mid-40s.

But as the old saying goes, "there are three kinds of lies: lies, damned lies, and statistics." Statistics in the 19th century were skewed by high childhood mortality rates—especially in urban areas—largely due to infectious diseases such as pertussis, measles, scarlet fever, and diphtheria. (Thanks to vaccination, these diseases are rare today.) By the time a person reached age 30 his life expectancy jumped to 67 and the average 50-year-old could expect to live until age 73.

Note that this still puts many of my ancestors above average, but that's no surprise.  :)

My go-to example of what young people can accomplish has always been David Farragut, midshipman in the U.S. Navy at age nine, given charge of a prize ship at 12, later the Navy's first admiral.  But the Occasional CEO has provided some other examples for my list:

In 1792, the trading ship Benjamin departed Salem, Massachusetts, loaded with hops, saddlery, window glass, mahogany boards, tobacco and Madeira wine.  The ship and crew would be gone for 19 months, traveling to the Cape of Good Hope and Il de France.   All the while they bargained hard from port to port, flipping their freight several times “amid embargoes and revolutions,” naval historian Samuel Eliot Morison wrote, “slipping their cables at Capetown after dark in a gale of wind to escape a British frigate; drifting out of Bourbon with ebb tide to elude a French brig-o’-war.”  In 1794, the Benjamin returned to Salem with a cargo that brought 500% profit to its owners.

The ship just happened to be captained by Nathaniel Silsbee, 19 years old when he took command.  His first mate was 20 and his clerk 18.

I know we expect a different sort of education for our young people today, but surely we can do a better job of helping them get it more efficiently.  No wonder today's teens are restive!

The final of the three articles I chose from the January-February issue of Christianity Today is "Who Owns the Pastor's Sermon?" which dives into the thorny issue of intellectual property rights.  If a church hires a pastor to preach sermons, do those sermons become church property, or does the preacher retain the copyrights?  Right now, the law favors the churches, which is why more pastors are seeking legal help to craft clear agreements.  Even though the focus of the article is entirely on pastors and sermons, church musicians, who frequently create intellectual property during the execution of their jobs, should take heed as well.

The law firm of Yates & Yates, which represents many Christian preacher-authors, has a standard agreement, which "recognizes that the pastor, as the creator, owns the intellectual property rights and has the right to determine copyright ownership. ... [T]he pastor grants the church a royalty-free license to use his written or recorded material."

It's the only arrangement that makes sense, said Yates. ... Preachers should own their sermons. If pastors don't own their sermons, that would essentially rob them of their livelihood. ... Pastors wouldn't be able to preach the same sermon in more than one place. And they wouldn't be able to take their sermon notes with them when they moved to a new church, which is "ridiculous," said Yates.

However, the legal situation is more complicated than this.

Frank Sommerville, a Dallas-based attorney who specializes in nonprofit law ... says that under the Copyright Act of 1976, a pastor's sermons qualify as "work for hire." That means the copyrights and intellectual property rights actually belong to their employer.

"It's not the answer that pastors expect," said Sommerville. "They've always taken the position that God gave them the sermon as part of their ministry. It never crossed their minds that there would be a law that would govern their sermons." (More)

Because there was actually only one great article in Three Great Articles - Part 1....

If our library is as good as it has been in acquiring books that I have suggested, eventually I'll post a review of The Locust Effect: Why the End of Poverty Requires the End of Violence.  In the meantime, this is the Christianity Today article that caught my attention:  Why We're Losing the War on Poverty, an interview with lawyer-activist-author Gary A. Haugen of the International Justice Mission.  (If you want to correct your view of lawyers as the scum of the earth, take a good look at IJM.)

Picture a poor farmer trying to scrape his way out of poverty. Just when the crops have started to show promise, the locusts descend and devour all of that hard work. That's the locust effect—the way violence impacts the poor in the developing world. The traditional things we do to assist the poor to get out of poverty don't stop the violence. The Locust Effect tells the story of the hidden plague of violence.

The lack of reliable law enforcement, Haugen argues, exposes the poor to the worst predatory violence, undermining the good accomplished by the billions of dollars aid agencies spend annually to fight poverty.

Haugen wants Westerners—and the aid agencies they support—to be as determined in fighting criminal violence against the poor as they are in relieving hunger and treating HIV/AIDS.

The problem is not that the poor don't get laws. The problem is that they don't get law enforcement. There is a functional collapse of law enforcement systems in the developing world; the poor are left utterly vulnerable to violence.

There's a problem with pouring aid into circumstances where poor people are not protected from predatory violence. ... [W]e are going to be significantly disappointed in the outcome of our poverty alleviation efforts.

When people think of poverty, they tell you what they see: the shacks, the dirty water, the hungry families. Those are all the visuals that immediately come to mind.

What they don't see are the assaults, the slap across the face, the rape, the torture by police, and the extortion. It's intentionally hidden by the perpetrator. The victims are scared and ashamed, and it's difficult for them to speak. People don't talk about the things they don't have solutions for. People working in the development field and in poverty-fighting or public health don't often come from law enforcement.

There is a solution for violence: the basic service the rest of us rely on every day, law enforcement.

The ideal partner is the body of Christ around the world. Westerners are not going to parachute in and save the day. This is a fundamental struggle for justice that's going to have to be owned by the local community.

Another partner will be governmental authorities within that community, within that country. This recovers Christian interaction with government. Romans 13 says the authorities are actually ministers of God in order to do justice in the community. Christians in other eras shaped the way the government went about seeking justice and peace in the community.

In the city of Cebu, Philippines, IJM partnered with community leaders to rally the justice system to protect children from sex trafficking. That's Project Lantern. One critical partner was the church, Protestant and Catholic. The victimization of children in the commercial sex trade was reduced by nearly 80 percent because law enforcement protected the children instead of the sex traffickers. ... It's now being replicated in Manila and Pampanga. We're also seeing the government itself beginning to foot the bill and take the initiative. IJM is a partner, but it's no longer the prime moving force. The government itself is setting up specialized units. Fast-track courts are being established to address sex trafficking. Safe places for the survivors of sex trafficking are being established. It's being taken nationwide in the Philippines.

I'm on the side of hope. I've seen it with my own eyes, and I've seen it profoundly in history.

We've subscribed to Christianity Today magazine for more years than I can remember.  The publication has been through many changes over the years, and I can't say as I've been happy with many of them, particularly its following of the deplorable trend of featuring images, pull-quotes, and short snippets instead of solid text.  If it wasn't designed by someone with ADHD, I'm guessing that's the audience they're reaching for.

On the other hand, CT is far from the worst offender in this, and besides, it makes for perfect bathroom reading.  There's no need to linger after the job is done just to finish a chapter.

Despite my complaints about the format, they do have some excellent articles not found elsewhere, and this year's January-February issue was a home run.  I'll mention three article of particular note.  Whether non-subscribers will be able to follow the links or not I don't now; they have a good deal of content available for free on their website, but what is and what isn't seems random to me.

The Surprising Discovery About Those Colonialist, Proselytizing Missionaries.  Sociologist Robert Woodberry's work was inspired by a mandatory lecture he attended while in graduate school:

The lecture was by Kenneth A. Bollen, a UNC–Chapel Hill professor and one of the leading experts on measuring and tracking the spread of global democracy. Bollen remarked that he kept finding a significant statistical link between democracy and Protestantism. Someone needed to study the reason for the link, he said.

Woodberry was hooked.  Warned by his professor that finding something positive about missionaries in the colonial era might scuttle his academic career, Woodberry was meticulous in his work and extraordinarily skeptical in his statistical analysis.  The correlation wouldn't go away: 

Areas where Protestant missionaries had a significant presence in the past are on average more economically developed today, with comparatively better health, lower infant mortality, lower corruption, greater literacy, higher educational attainment (especially for women), and more robust membership in nongovernmental associations.

"Missionary" is a broad term, and it's important to note that the correlation only applies to what the author calls "conversionary Protestants" who operated independently of the colonial powers.

Protestant clergy financed by the state, as well as Catholic missionaries prior to the 1960s, had no comparable effect in the areas where they worked.  Independence from state control made a big difference. "One of the main stereotypes about missions is that they were closely connected to colonialism," says Woodberry. "But Protestant missionaries not funded by the state were regularly very critical of colonialism."

"Why did some countries become democratic, while others went the route of theocracy or dictatorship?" asks Daniel Philpott, who teaches political science and peace studies at the University of Notre Dame. "For [Woodberry] to show through devastatingly thorough analysis that conversionary Protestants are crucial to what makes the country democratic today [is] remarkable in many ways. Not only is it another factor—it turns out to be the most important factor. It can't be anything but startling for scholars of democracy."

The missionaries didn't set out to fight social injustice, but they knew it when they saw it, and knew they had to do something about it.  Nor did it hurt their cause to have Christianity associated with someone helpful, rather than just the abusive rulers.  For example: (More)

Do most people read faster on an e-reader?

I've discovered that I can borrow books from our library for my Kindle, and this past Saturday I signed out The Hobbit.  That we have two physical copies on our shelves is beside the point:  Kindle books are the most comfortable way to read in bed—at least under our present lighting setup—and that's what I wanted it for.  As a tried-and-true introvert, my brain is always spinning rapidly, and if I don't get sufficient, effective processing time during the day—and sometimes even if I do—trying to fall asleep is like putting in the clutch while opening the throttle:  high rpms with no actual progress made.  Reading a few chapters of a good book engages the engine and throttles back to where sleep can take over.

For physical books, our library's default loan period is three weeks.  The default loan period for e-books is one week.

The downside of so much exposure to Facebook and other modern communication is that I am tempted at this point to write, "WTF?"  Instead, I will try to remember what we all said before that offensive term became so common as to jump immediately even to my own mind, and simply say, "Huh?"  I find reading a book a week to be an ambitious goal.

I don't think I read any faster (or slower) on the Kindle than with the printed page.  Do you?

Jon found this amazing furniture designed for small spaces.  This is what happens when artists and engineers collaborate!  I find it terrific!

There's only one tiny problem:  It appears that if you can afford this furniture, you can afford a larger apartment.

No prices are listed, but Jon's e-mail inquiry about the bunk beds is rather discouraging.  (I rounded the numbers, but you get the idea.)

  • Beds:  $5,000 - $8,000
  • Folding headboards (each):  $500
  • Folding desk under lower bunk:  $1000
  • Twin mattresss (each):  $500 - $1000

Minimum $6,000 for a set of bunk beds?  Add the headboards and a desk and it will set you back at least $8,000?  (Plus taxes and shipping no doubt.)  They're very clever, and I'm sure they're well-built—probably not in China, though I haven't found any evidence to back up that speculation—but yikes!

My nephew T got his driver's permit recently.  I didn't find that at all surprising—until I read that the percentage of young people becoming licensed drivers has dropped radically since at least 1983.  In that year, 46% of 16-year-old had their licenses; by 2010 that had plummeted to 28%.

Why?  Reasons suggested range from reasonable to ridiculous, from encourging to frightening.  Some of them (in no particular order):

  1. Too busy
  2. Too expensive
  3. Driving interferes with texting
  4. Online resources make travel less necessary
  5. Preference for public transit/biking/walking
  6. Changes in licensing requirements

#1 I haven't figured out yet.  Most DMV lines are long, but not that long.

#2 I understand as a reason to put off buying a car, but not a reason for not getting a license.  A 16-year-old should be happy enough using the family car, and an older, "boomerang kid" still living at home should welcome the opportunity to assist the parents who are still supporting him.  Owning a car isn't a prerequisite for acquiring a license!

#3 Okay, once I got over the ridiculousness of being so addicted to your phone that you refuse to drive because most states don't allow texting while driving, I acknowledge that being able to do something else while travelling is one of the great advantages of public transit.  My father was a book lover with not a lot of spare time; taking the train to work was like being handed an extra hour to read.

#4 Very true.  Since I hate to shop, I really appreciate being able to do much of it online.  And watching movies at home is much nicer than getting my feet sticky in a movie theater.  But even here in Switzerland, which has the best public transit I've seen anywhere, most people find they have need for a car—if not actually owning one, at least subscribing to a car-sharing service.

#5 The best reason of all.  I'm thrilled that it's becoming "cool" to use public transit.  I've said for a long time that public transit, along with walking and biking for transport (as opposed to exercise or sport), will never make it in the U.S. until it shakes its image of being just for the poor and for drunks who have had their driver's licenses taken way.  But see my comment on #4.

#6  There needs to be more said about this than I've heard so far.  Getting a license used to be straightforward and relatively easy, even when it became more restrictive than it was for our parents:  "This is my daughter.  She can drive; give her a license." "Okay, ma'am; here it is."  Many states have become increasingly restrictive when it comes to licensing young people, with more rules than I've been able to keep track of, rules that take away much of the immediate incentive for learning to drive.  If they can't drive themselves home after a football game (too late at night) and can't provide transportation for their friends (passenger limits), who can blame many young people for finding the whole process too much hassle to bother with, since they can get fully licensed with ease in just a few more years?

"There's a segment of this generation missing opportunities to learn under the safeguards that [graduated licensing] provides," said Peter Kissinger, the president of the AAA Foundation for Traffic safety.

All I can say to that is that they brought it on themselves by in effect telling young people they are irresponsible idiots.  Who can blame those who decide to chuck the whole system?

Don't miss the latest post from the Occasional CEO.  I don't have time now to summarize it, so you'll have to read the whole thing, which you should anyway.  Here's a teaser:

I truly appreciate software.  I also love my cotton Hanes, sugar on my Grapenuts and enough gas to get to the beach this summer.  But, if there’s nothing else three centuries of sugar, cotton and oil have taught, it’s that first we own the advantaged commodity, and then it owns us.

Most of you know that I'm not fond of Presbyterian sermons.  In my experience, even if they're good they're too long, because the preacher says everything three times.  But I'm posting this for three reasons:

  • It's local:  First Presbyterian Church of Orlando.  It was never our church, but both kids had musical gigs there at one time or another.
  • It's fascinating:  I'd never have guessed this was a Presbyterian preacher.  Baptist maybe.  Even Pentacostal.  But Frozen Chosen?  Nah.
  • It's a good take on the whole egalitarian/complementarian debate, with points for both sides.

Do I agree with everything? Rhetorical question.  You know I never do.  But you know there must be something to it if I think a sermon that long is worth listening to.

My husband likes to tell this story about one day when I was coming to pick him up from work:

He was in a hurry to get going, so instead of waiting at the office, where I was expecting him, he walked up the street to the main road, thus saving—or so he hoped—the time it would take me to drive down the street and turn around.

The plan backfired, however, because I, concentrating on the job at hand, didn't see him waving frantically on the sidewalk.  I drove to the usual place, and he had to walk back.

Thanks to our alma mater, I finally have a comeback for those embarrassing moments when the entire lunch table is thinking, "How dumb can this woman be?"

I didn't see him where I didn't expect him, not because I am stupid, but because I am highly intelligent!

Check it out:  a study at the University of Rochester has discovered a strong correlation between high intelligence and a significantly reduced ability to notice background motions.

The authors explain that in most scenarios, background movement is less important than small moving objects in the foreground, for example driving a car, walking down a hall or moving your eyes across the room.

As a person's IQ increases, so too does his or her ability to filter out distracting background motion and concentrate on the foreground.

In an initial study on 12 people, there was a 64% correlation between motion suppression and IQ scores. In this larger study on 53 people, a 71% correlation was found.

Ha!
