Is ‘galvanic skin response’ a way to measure how much kids learn?

By David McElroy · June 15, 2012

Why has the modern educational establishment become so obsessed with standardized testing and uniformity of measurement? When did so many people start believing that you could plot learning as numbers and graphs — and still teach children what they need to know?

That’s what I kept thinking as I read about a $1.1 million project to look into designing “galvanic skin response” bracelets for students to wear that would measure their degree of engagement with what they were listening to. The goal is to find out whether physiological feedback from these sensors could tell teachers whether students are learning or not.

If you’re not familiar with the phrase “galvanic skin response,” it’s just the name for the process of measuring how electricity flows through the skin depending on changes in moisture. It’s the principle upon which so-called lie detectors work. (Those things are bogus, but that’s another story entirely.)

Is this really the way some people believe we should decide whether kids are learning? Are we going to keep going until we strap a sensor helmet on kids every morning so we can monitor their thoughts for the full day?

Town’s new fine for public profanity points to problem of ‘public’ spaces

By David McElroy · June 14, 2012

If you plan to spend any time in Middleborough, Mass., you might want to be careful if you’re the sort who enjoys slinging four-letter words around. The town’s residents voted 183-50 Monday night to enact a fine for the public use of profanity, so police will have their ears open.

In modern American society, this is typically seen as a conflict between free speech and civility. Some people believe you should be able to say anything you want without government interference, and others believe that offensive and vulgar behavior should be prohibited. Merchants in the town say some of their customers have been uncomfortable with groups of teens hanging out downtown and swearing loudly. So which side is right?

I’m an advocate of keeping government completely out of the business of censoring speech, but I’m also someone who detests profanity. (I’m one of the few people you know who you’ll never hear it from. I didn’t grow up with it and I’ve consciously avoided using it. It’s not what I want to be.) So it sounds as though these two competing values are in conflict and there’s no logical way to resolve it.

That’s sort of true. There’s no logical way to resolve it under the current system of “public” ownership of property and the rules that come with “public” space. But what if the real issue isn’t free speech vs. civility? What if the real issue is who owns property — and who should be allowed to make the rules?

EU says it might block people from getting their own money from banks

By David McElroy · June 13, 2012

So you think the money you have in the bank belongs to you, huh? Does it really? The Europeans who have money deposited in their banks thought the same thing. Now that the continent is a financial basket case and the joint currency is on the verge of falling apart, Europeans are learning who controls their money. Will Americans be far behind in learning the same thing?

As it starts to seem likely to Greece will pull out of the eurozone and go back to its own currency, EU officials are trying to figure out what to do. One of the possibilities that they’re considering is limiting the amount of money that people are allowed to withdraw from banks. Another is instituting border checks and “capital controls.” (That’s a polite way of saying that people can’t move their money out of the country.)

If someone can tell you that you can’t have access to your money, is it really yours? If someone can tell you that you can’t spend your money out of the country — or send it to a bank account somewhere else — is it really your money?

So whose money is it? There’s a story in several of the New Testament Gospels in which Jesus addressed this question. It’s been used by many people to say that Jesus told people to pay taxes, but let’s look at what it actually says. This account is from Mark 12:13-17:

Future Photo Display

As part of my effort to rid my life of social media, I will no longer display links to my two Instagram accounts here. Those accounts will be dormant for the time being and will eventually be deleted. I plan to have a method for displaying photos here instead, but the solutions I’ve tested so far have been disappointing. I’m still working on it.

She’s been a great addition to the household.
By the time I left the office about 5:30 p.m. Frid By the time I left the office about 5:30 p.m. Friday, some light rain from the approaching hurricane was starting to fall. It’s been completely cloudy in Birmingham all day because of the bands of clouds pushing north from the Gulf of Mexico. About halfway home, I noticed that the sky had suddenly started exhibiting this beautiful orange glow to the west. So even though it was far too cloudy for us to see a real sunset, the light was still colorful enough and bright enough to punch through at the horizon. So I stopped on the Cahaba River bridge on I-459 and caught this quick shot. Within just a couple of minutes, the clouds had covered up the color — and the rain started getting a bit harder. By morning, we should have howling winds and serious thunderstorms. Let’s just hope there are no tornados spawned by this storm in our area.

I loved finding the pictures, but seeing these photos left me thinking about the effect it has on us when we lose an animal we love — and it was also a reminder of how much my life has changed for the last nine months it’s been since I lost her. I wrote an essay about this. You can find it as the most recent post at davidmcelroy.org right now if you’re interested. I really do miss this sweet girl.

It’s very relaxing to stand at my back door and watch this, especially since the heat is pretty mild today — 80 degrees (about 26 celsius) — for July in the American South.

For the first few weeks, she spent much of her time in the bedroom underneath a chair. But in the last few days, she’s spending much of her time in the cave of the castle while the other three cats relax nearby. I think she’s getting happier and more comfortable every day.

Briefly

Here’s another reason to appreciate the cats in your life: New research involving 93 countries found that places with more cats per person also tended to have happier people. The researchers say the finding fits with previous evidence that living with pets can reduce loneliness and stress while providing companionship, emotional attachment and social support. The study doesn’t prove that cats cause greater happiness, but it certainly adds to the evidence that sharing your home — and your life — with a cat might be good for you.

The company that owns Facebook and Instagram is heavily promoting its new AI-based software assistant called Muse, but people who are using it as it was designed are incredibly foolish. An early adopter of the software discovered that a few days ago when he advertised an item for sale on Facebook Marketplace — and he inadvertently gave Muse full authority to act on his behalf. The software agreed to a lowball offer made by another Facebook user and then gave that man the home address of the man for whom he was an agent. The software told the buyer that the seller was home and waiting for him. When the buyer showed up and waited angrily, the would-be buyer left an angry review for the man. And this angry man had the seller’s home address. It was only well after that that the software reported what it had done and admitted it had made a mistake. I won’t be putting that much power into the hands of any software. I think anyone who agrees to such terms is a fool. And the software’s user agreement says you’re responsible for purchases the software makes in your name. Nope.

Meet my new girlfriend. Her name is Meg. And she’s my little sweetheart. A couple of months ago, a neighbor across the street told me about a new stray in the neighborhood that she and I were both soon feeding. The cat had been very skittish about contact and she had a lot of scabs and parasites in her fur, but a trip to the vet last week revealed that she was otherwise in good health. The vet estimates her to be 1 to 2 years old. I named her for Meg Murry, the 13-year-old protagonist of Madeleine L’Engle’s wonderful book, “A Wrinkle in Time.” (Please read the book. Don’t watch the horrible movie.) Since we lost Lucy almost a year ago, it seems appropriate that we finally have a new little girl to join the household. She’s already captured my heart, but Alex, Oliver and Sam aren’t there quite yet.

There’s nothing socially acceptable that’s as dangerous as drinking alcohol. Most people grow up being told to “drink responsibly” — and all of us see people abusing this drug in one way or another — but the truth is that drinking alcohol is always a terrible risk. The alcohol in these drinks is toxic and the human liver has to work hard to filter the toxins out. What most people don’t realize is that alcohol is classified as a known carcinogen by the World Health Organization — because of the well-established connection between imbibing and various cancers. Many people have taken refuge behind the idea that light or moderate drinking might be safe, but a new study shows that drinking even one drink a day increases the risks of 10 types of cancer. When I was a teen-ager, I looked around and saw the negative effects that this behavior had on a lot of people and decided not to start drinking, so I’ve never even tried this poison. The evidence keeps piling up that I was lucky to have come to that conclusion early.

It turns out that the radical far left has been training “Antifa cats” to sabotage anything important to Donald Trump. Everything he did was perfect. Honest. It was all the cats’ fault. Arrest all the cats! This is the latest of my ridiculous satirical shorts. Please go watch it. Then “like” it and subscribe. Please. I’m begging you. (Too much?) Although a couple of the previous videos have had views in the hundreds, most have still been seen by fewer than 20 people. So I seem to be having trouble letting people know that page exists.
