No Evidence Base that Smartphones Cause Anxiety and Depression in Teens

(p. B1) SAN FRANCISCO — It has become common wisdom that too much time spent on smartphones and social media is responsible for a recent spike in anxiety, depression and other mental health problems, especially among teenagers.

But a growing number of academic researchers have produced studies that suggest the common wisdom is wrong.

The latest research, published on Friday [January 17, 2020] by two psychology professors, combs through about 40 studies that have examined the link between social media use and both depression and anxiety among adolescents. That link, according to the professors, is small and inconsistent.

“There doesn’t seem to be an evidence base that would explain the level of panic and consternation around these issues,” said Candice L. Odgers, a professor at the University of California, Irvine, and the lead author of the paper, which was published in the Journal of Child Psychology and Psychiatry.

“Still a Beacon, Still a Magnet for All Who Must Have Freedom”

(p. A23) . . . Ronald Reagan believed in the possibilities of a country that was forever reinventing itself. He knew, too, that the nation had grown stronger the more widely it had opened its arms and the more generously it had interpreted Thomas Jefferson’s assertion of equality in the Declaration of Independence.

He was about hope, not fear. And that is another reason his farewell address should be more widely appreciated: It’s a kind of final testament of an American president who had a genuine faith in the future. Mr. Reagan was a practical man, and he knew, as he put it, that “because we’re a great nation, our challenges seem complex. It will always be this way. But as long as we remember our first principles and believe in ourselves, the future will be ours.”

Or so we can hope. His last words on that long-ago Wednesday bear hearing, and pondering. “And how stands the city on this winter night?” Mr. Reagan asked. “More prosperous, more secure and happier than it was eight years ago. She’s still a beacon, still a magnet for all who must have freedom, for all the pilgrims from all the lost places who are hurtling through the darkness, toward home.”

They hurtle through that darkness even now. Mr. Reagan would have us light the lamp and open our arms — for that’s what cities on a hill do.

“The Churning, Extravagant, Perfectionist Imagination of” Walt Disney

(p. A15) As understatements go, this one’s a doozy. Its source was Roy Disney, the less heralded, less handsome and—as gleaned from Richard Snow’s richly engaging “Disney’s Land”—less headstrong brother of Walt Disney. Since 1923, Roy had been the business brains of the Disney company was no stranger to his kid brother’s “screwy ideas.” But when he was informed after the war that his sibling had been, over his objections, slyly seeking funds to develop his own amusement park, Roy’s response was: “Junior’s got his hand in the cookie jar again.”

. . .

. . . when Roy first happened upon his brother’s maneuvering, amusement parks were passé at best, crime-ridden at worst and financial sinkholes at their core. Walt, having hired the Stanford Research Institute for a feasibility study, was told that he would fail if his park didn’t include such proven winners as a Ferris wheel, a roller coaster and games of chance—none of which Walt wanted cluttering his dreamscape.

Joining the chorus of dissent was Walt’s wife, Lillian. She had tolerated her hobbyist-husband taking over her backyard rose garden with his steam locomotive, but she “raised the dickens” (Walt’s words) when her perennially boyish 52-year-old spouse told her that he had sold their desert vacation home and borrowed $250,000 against his life insurance so that he could seed his plans for the sort of enterprise that looked to be, as she put it, “not fun at all for grown-ups.”

. . .

Roy, Mr. Snow acknowledges, “never lost his calm understanding that the company’s prosperity rested not on the rock of conventional business practices, but on the churning, extravagant, perfectionist imagination of his younger brother.” For Walt’s part, he is quoted saying in 1957, just as Disneyland was making him rich, that “if it hadn’t been for my big brother, I swear I’d’ve been in jail several times for checks bouncing.”

The Creative Destruction of Broadcast TV by Streaming, Increases Variety

(p. B4) It has been on a steep upward trajectory for years, and in 2019, it finally happened.

There were more than 500 scripted television series in the United States last year, a high. The estimated number: 532 comedies, dramas and limited series that were broadcast or streamed, according to the research department of the cable network FX, which tabulates and releases the figure every year.

It marked the first time the 500-show threshold had been crossed, representing a 7 percent increase over the number of scripted shows in 2018.

The 2019 total was 52 percent more than the 349 shows that existed in 2013, the year that streaming started to become a habit for many viewers, with the debut of “House of Cards” on Netflix. And it’s a jump of 153 percent over the 210 series available in 2009.

“You Escaped China, but Now You’re Supporting Them”

(p. A6) HONG KONG — The tapioca pearls at Fred Liu’s bubble teahouse are springy and fresh, just like the fish balls at Elaine Lau’s noodle shop. But that is not the only reason customers flock to these eateries in Hong Kong’s bustling Causeway Bay shopping district.

Both are members of the so-called yellow economy, shops that openly support the democracy movement remaking Hong Kong as it strives to protect the freedoms differentiating the territory from the rest of China.

After seven months of street protests against Beijing’s assault on these liberties, Hong Kong is color-coded — and bitterly divided. The yellow economy refers to the hue of umbrellas once used to defend demonstrators against pepper spray and streams of tear gas. That is in contrast to blue businesses, which support the police.

. . .

As the protests gathered force last year, Rocky Siu watched as an orderly column of demonstrators, miles long, marched past one of his ramen restaurants. When the police cracked down, he opened his doors, offering half-price bowls of noodles and free saline solution to wash the tear gas from protesters’ eyes.

“I’m losing money, but that’s not the point,” he said. “We have to support our young people.”

Mr. Siu’s father was born in China and came to Hong Kong to seek a better life. But he owns a jewelry factory on the mainland and is, as Mr. Siu puts it, “deep blue.”

“I tell him, ‘I don’t understand. You escaped China, but now you’re supporting them,’” Mr. Siu said. “To me, it’s not yellow or blue. It’s black and white, right and wrong.”

A.I. Makes Surgeons More Efficient, but Does Not Replace Them

(p. B6) Brain surgeons are bringing artificial intelligence and new imaging techniques into the operating room, to diagnose tumors as accurately as pathologists, and much faster, according to a report in the journal Nature Medicine.

The new approach streamlines the standard practice of analyzing tissue samples while the patient is still on the operating table, to help guide brain surgery and later treatment.

The traditional method, which requires sending the tissue to a lab, freezing and staining it, then peering at it through a microscope, takes 20 to 30 minutes or longer. The new technique takes two and a half minutes. Like the old method, it requires that tissue be removed from the brain, but uses lasers to create images and a computer to read them in the operating room.

. . .

Some types of brain tumor are so rare that there is not enough data on them to train an A.I. system, so the system in the study was designed to essentially toss out samples it could not identify.

Over all, the system did make mistakes: It misdiagnosed 14 cases that the humans got right. And the doctors missed 17 cases that the computer got right.

“I couldn’t have hoped for a better result,” Dr. Orringer said. “It’s exciting. It says the combination of an algorithm plus human intuition improves our ability to predict diagnosis.”

In his own practice, Dr. Orringer said that he often used the system to determine quickly whether he had removed as much of a brain tumor as possible, or should keep cutting.

“If I have six questions during an operation, I can get them answered without having six times 30 or 40 minutes,” he said. “I didn’t do this before. It’s a lot of burden to the patient to be under anesthesia for that long.”

Dr. Bederson said that he had participated in a pilot study of a system similar to the one in the study and wanted to use it, and that his hospital was considering acquiring the technology.

“It won’t change brain surgery,” he said, “but it’s going to add a significant new tool, more significant than they’ve stated.”
