Feed your baby peanuts to prevent peanut allergies

We randomly assigned 640 infants with severe eczema, egg allergy, or both to consume or avoid peanuts until 60 months of age. Participants, who were at least 4 months but younger than 11 months of age at randomization, were assigned to separate study cohorts on the basis of preexisting sensitivity to peanut extract, which was determined with the use of a skin-prick test...

Among the 530 infants in the intention-to-treat population who initially had negative results on the skin-prick test, the prevalence of peanut allergy at 60 months of age was 13.7% in the avoidance group and 1.9% in the consumption group (P < 0.001). Among the 98 participants in the intention-to-treat population who initially had positive test results, the prevalence of peanut allergy was 35.3% in the avoidance group and 10.6% in the consumption group (P = 0.004). There was no significant between-group difference in the incidence of serious adverse events.

The early introduction of peanuts significantly decreased the frequency of the development of peanut allergy among children at high risk for this allergy and modulated immune responses to peanuts.

Why ramen is better in Japan

In Japan, flour companies have different divisions that make flour for noodles. In general, this flour is milled as much as ten times more finely than it is here. The flour doesn’t need to be as absorbent here in the U.S.—it’s primarily for bread production. So there’s not as much of a reason to mill it as fine. The result is that it’s harder to make a proper ramen noodle here, since the flour is just not fine enough.

Relative to pasta, ramen noodles are on the low end of the water-content spectrum—some can contain as little as 26 percent water. ... The more refined your flour, the better it will bind with water, and the better the texture of the final noodle.

When I talk to our flour salesman in Tokyo, I can say, “I’m thinking about making a tsukemen noodle, and I want it to be aromatic and have a chew,” and he’ll send me samples that make sense. Then we can talk on the phone and I can say, “I want my ash content to be a bit lower or higher” or “I want to be able to see more or less of the grain color in the noodle.” I can really talk to them and have a super intellectual conversation, and at the end of the day you’re able to make a really good product.

This is all to say that when I came back to New York, I felt like making my own noodles would be too big of a challenge. I had already met Ken Uki, of Sun Noodle, and I had worked with him a little bit. He’d done a really good job; they run a really professional operation. So I decided to take making noodles off of my plate. ...

In Japan, you can get great chicken fat for cheap. It’s orange and it doesn’t taste funky—it almost tastes like chicken soup. ...

You can’t get good chicken fat here in the States. A USDA plant needs approval for each part of the animal they want to use: necks, wings, heads, whatever. A guy at one of the chicken farms we use says he throws all his chicken fat away; it’s too much of a hassle to get it USDA approved, and nobody wants to buy it.

So I use whatever I can get. It’s not bad. It’s good, but it’s not as delicious. At the shop, people are like, You could use Flying Pigs Farms or whatever, and it’s like, Yeah, but they want $15 per pound for their birds. Then they’ll say, Why don’t you use pastured, sustainable, organic meat? And I’m like, Will you pay $25 per bowl of ramen?

The one-part Tversky Intelligence Test

As recounted by Malcolm Gladwell in 2013's David and Goliath: Underdogs, Misfits, and the Art of Battling Giants, [Amos] Tversky's peers thought so highly of him that they devised a tongue-in-cheek one-part test for measuring intelligence. As related to Gladwell by psychologist Adam Alter, the Tversky Intelligence Test was "The faster you realized Tversky was smarter than you, the smarter you were."

The progressive weakening of Harvard

“Harvard University will close only for an act of God, such as the end of the world,” former Harvard Dean of Students Archie Epps III once said. If so, Harvard has seen a lot of evidence of The Almighty One these past few years.

Harvard schools have canceled classes on both Monday and Tuesday due to the latest snowstorm, which so far has dropped two feet of snow on the area and shut down the MBTA. That comes two weeks after the university suspended all operations on January 27 for the blizzard that led to a state of emergency and a travel ban across the state.

There was a time not long ago when canceling a single day of Harvard classes — not to mention three in one semester — would have been a surprise. Administrators called off three days of classes for the historic Blizzard of 1978, the first cancellation since an unnamed hurricane in 1938. Classes also closed in 1985 due to Hurricane Gloria.

But that was it for the entire 20th century. In 100 years, Harvard canceled classes only three times. ...

Graduate schools closed down classes in January 2011 after about 18 inches of snow. Harvard canceled all classes on October 29, 2012 ahead of the high winds and rain of Hurricane Sandy. The blizzard of February 2013 slammed the campus on a weekend, and university libraries were shut down. Officials also canceled classes on April 19, 2013 amid the manhunt for Dzhokhar Tsarnaev after the Boston Marathon bombing.

For undergraduates, there have been as many days off at Harvard in the last five years as there were in the entire 20th century.

Finns ration their hellos

“Well, you’re just special. You’re American,” remarked my colleague, smirking from across the coffee table. My other Finnish coworkers, from the school in Helsinki where I teach, nodded in agreement. They had just finished critiquing one of my habits, and they could see that I was on the defensive.

I threw my hands up and snapped, “You’re accusing me of being too friendly? Is that really such a bad thing?”

“Well, when I greet a colleague, I keep track,” she retorted, “so I don’t greet them again during the day!” Another chimed in, “That’s the same for me, too!”

The Crusades were not what you think they were

Westerners in general (and Catholics in particular) find the Crusades a deeply embarrassing episode in their history. ...

On September 11, 2001, there were only a few professional historians of the Crusades in America. I was the one who was not retired. As a result, my phone began ringing and didn’t stop for years. ...

It is generally thought that Christians attacked Muslims without provocation to seize their lands and forcibly convert them. The Crusaders were Europe’s lacklands and ne’er-do-wells, who marched against the infidels out of blind zealotry and a desire for booty and land. As such, the Crusades betrayed Christianity itself. They transformed “turn the other cheek” into “kill them all; God will know his own.”

Every word of this is wrong. Historians of the Crusades have long known that it is wrong, but they find it extraordinarily difficult to be heard across a chasm of entrenched preconceptions. ...

All the Crusades met the criteria of just wars. They came about in reaction [to] attacks against Christians or their Church. The First Crusade was called in 1095 in response to the recent Turkish conquest of Christian Asia Minor, as well as the much earlier Arab conquest of the Christian-held Holy Land. The second was called in response to the Muslim conquest of Edessa in 1144. The third was called in response to the Muslim conquest of Jerusalem and most other Christian lands in the Levant in 1187.

In each case, the faithful went to war to defend Christians, to punish the attackers, and to right terrible wrongs. As Riley-Smith has written elsewhere, crusading was seen as an act of love—specifically the love of God and the love of neighbor. By pushing back Muslim aggression and restoring Eastern Christianity, the Crusaders were—at great peril to themselves—imitating the Good Samaritan. ...

Historians have long known that the image of the Crusader as an adventurer seeking his fortune is exactly backward. The vast majority of Crusaders returned home as soon as they had fulfilled their vow. What little booty they could acquire was more than spent on the journey itself. One is hard pressed to name a single returning Crusader who broke even, let alone made a profit on the journey. ...

It is commonly thought—even by Muslims—that the effects and memory of that trauma have been with the Islamic world since it was first inflicted in the eleventh century. As Riley-Smith explains, however, the Muslim memory of the Crusades is of very recent vintage. ... When, in 1291, Muslim armies removed the last vestiges of the Crusader Kingdom from Palestine, the Crusades largely dropped out of Muslim memory.

In Europe, however, the Crusades were a well-remembered formative episode. Europeans, who had bound the Crusades to imperialism, brought the story to the Middle East during the nineteenth century and reintroduced it to the Muslims. ...

Riley-Smith describes the profound effect that Sir Walter Scott’s novel The Talisman had on European and therefore Middle Eastern opinion of the Crusades. Crusaders such as Richard the Lionhearted were portrayed as boorish, brutal, and childish, while Muslims, particularly Saladin, were tolerant and enlightened gentlemen of the nineteenth century. With the collapse of Ottoman power and the rise of Arab nationalism at the end of the nineteenth century, Muslims bound together these two strands of Crusade narrative and created a new memory in which the Crusades were only the first part of Europe’s assault on Islam—an assault that continued through the modern imperialism of European powers. Europeans reintroduced Saladin, who had been nearly forgotten in the Middle East, and Arab nationalists then cleansed him of his Kurdish ethnicity to create a new anti-Western hero.

A better way to pay ransom to kidnappers

It all began in 2003, when a German official flew into the wilds of northern Mali with three suitcases full of cash to secure the release of 14 European hostages. That first big ransom breathed life into the militant group known as Al Qaeda in the Islamic Maghreb, and laid the groundwork for a kidnap economy that now finances Islamist extremist groups around the globe.

Foreigners who stumble into this world are highly prized assets: They are tracked, abducted, sold from one militant group to another and held for months, or even years, in the hope of a multimillion-dollar payday. Such hopes are kept alive by France, Germany and other European governments that routinely facilitate ransom payments for the release of their own citizens.

The United States steadfastly refuses to pay ransom, which undoubtedly reduces the price that American hostages fetch in the kidnap economy. However, money isn’t the only motivator for those holding hostages; they are also used to demonstrate the groups’ ferocity, as shown recently by the Islamic State’s gruesome killings of two Japanese men. ...

The good news is there is a way to change this game, to turn the tables on terrorist kidnappers and undermine the kidnap economy. ...

Throughout the 1980s, federal investigators did not catch a single major business cartel, despite having a whole division at the Department of Justice devoted to the task. That’s because business cartels, groups of companies that work together in secret to fix prices, can be nearly impossible to detect. ...

That all changed, suddenly and dramatically, in 1993 when the Department of Justice instituted a new program offering complete immunity to the first firm in a cartel to confess. ...

And turn on each other they did; soon convictions and settlements in the United States alone were generating hundreds of millions of dollars in fines each year. ...

Imagine what would happen if the federal government were to offer a million-dollar reward and promise safety to anyone — Islamic State militant or not — who provided information that led to the rescue of American hostages, and the capture or killing of their kidnappers. Holding an American hostage would then become fraught with peril, no matter where the kidnappers might hide, as anyone, even one of their own, might turn on them at any time.

Why you often shouldn't go for it on 4th down

It doesn’t matter the distance; kicking has been on a steady upward climb. If we look back even further, we can see indicators that kicking has been on a similar trajectory for the entire history of the league. ...

If you’re reading this site, there’s a good chance you scream at your television a lot when coaches sheepishly kick or punt instead of going for it on fourth down. This is particularly true in the “dead zone” between roughly the 25- and 40-yard lines, where punts accomplish little and field goals are supposedly too long to be good gambles. ...

As of 10 years ago — around when these should-we-go-for-it models rose to prominence — we were still right. But a lot has changed in 10 years. Field-goal kicking is now good enough that many previous calculations are outdated. ...

There’s no one universally agreed-upon system for when you should go for it on fourth down. But a very popular one is The New York Times’ 4th Down Bot...

Comparing those to my model, it looks to me like the bot’s kickers are approximately 2004-quality. (I asked Burke about this, and he agrees that the bot is probably at least a few years behind, and says that its kicking assumptions are based on a fitted model of the most recent eight years of kicking data.) ...

The following table compares “Go or No” charts from the 4th Down Bot as it stands right now, versus how it would look with projected 2015 kickers:
Having better kickers makes a big difference, as you can see from the blue sea on the left versus the red sea on the right. ...

While the updated version still concluded that coaches were too conservative (particularly on fourth-and-short), it found that coaches were (very slightly) making more correct decisions than the 4th Down Bot.

Why you shouldn't become a professional cartoonist

[Tom] Toro has since moved into his own apartment, and he continues to submit a dozen or so cartoons to the New Yorker weekly. In the past year and a half, the magazine has bought 16 of his 1,600 submissions. "It's a kind of life of rejection," Toro deadpans. "It's a bittersweet game of odds, and you have to overwhelm them."

Among the bittersweet realities of Toro's cartooning success is that the pay is mediocre. The New Yorker abandoned its staff cartoonists several years ago and now offers its stable of 30 or so regular ones a fee of $675 per cartoon, with old-timers such as Roz Chast and George Booth probably earning more.
--Tamara Straus, SFGate, on overwhelming supply meeting tepid demand. FYI, 16 * 675 / 1.5 = $7,200 per year

Every cartoonist I know has a second career doing something else, or is married to a lawyer. How I make ends meet is I work part-time customer service jobs, and if that’s not enough I shamelessly mooch off my parents. I’m almost thirty-two years old. Welcome to the paradise of the modern artist. ...

This is pretty much the plateau. There’s no better venue than The New Yorker. It’s the acme of cartooning.

609 rejections later...

Tom Toro didn't always dream of becoming a cartoonist at The New Yorker. Sure, he drew cartoons in college, but he didn't see that as a career path. Instead, he went to film school at NYU.

Then he came to the sudden realization that he was in the wrong field — and he had no idea what he was going to do.

"Up to my neck in debt, directionless, feeling lost in the huge city," Tom Toro says. "I went into a pretty dark depression. I ended up dropping out of film school. I floundered around for a little while, and I finally just had to come back home." ...

"I had sort of been a golden child," he says. "I was valedictorian in my high school class, I went to Yale, I got into NYU right out of undergrad, and all of a sudden, I'm back at home. " ...

One afternoon, Toro went to a used book sale in his hometown. He opened a cardboard box and found an old stack of magazines. ...

They were stacks of old New Yorkers.

"There they were, these cartoons in among the articles," he says. "I don't know. Something just clicked. And I started drawing again."

Toro decided to submit some of his work to the magazine. ...

Shortly after, he received a reply in the mail: It was his first rejection note.

"It's like two of the most elegantly phrased sentences," he says. "The New Yorker found the way to most courteously and most briefly reject people. It's just beautiful. You feel so honored to receive it and yet it's a brushoff." ...

A year and a half later, Toro had a pile of rejection letters. But instead of feeling discouraged, he says, it only fueled his determination. ...

And then, one day, he wandered into his mom's office to check his email.

"Went in there, logged in, and there sitting at the top of my inbox was an email from [Bob Mankoff's] assistant," Toro says.

The subject line read, "Cartoon Sold."

It was the 610th drawing Toro had submitted to The New Yorker.

Why New York state politicians are so corrupt

Wilson’s (1966) seminal contribution argued that state-level politics was particularly prone to corruption because state capitals are often far from the major metropolitan centers, and thus face a lower level of scrutiny by citizens and by the media...

Our first contribution is to establish a basic stylized fact that is very much in line with this “accountability view”: isolated US state capital cities are associated with higher levels of corruption. A simple depiction of that can be seen in Figure 1, where our baseline measure of corruption is plotted against our baseline measure of the isolation of a state’s capital city. ...

When it comes to the media, we show that newspapers give more coverage to state politics when their readership is more concentrated around the state capital city. This is matched by individual-level patterns: individuals who live farther from the state capital are less informed and display less interest in state politics, but not in politics in general.

When it comes to elections, we find that voter turnout in state elections is greater in counties that are closer to the state capital. In addition, we also show that isolated capital cities are associated with a greater role for money in state-level elections, as measured by campaign contributions, and that, in states with a relatively isolated capital, firms and individuals who are closer to it contribute disproportionately more. ...

Finally, we provide some evidence on whether this pattern of low accountability affects the ultimate provision of public goods: states with isolated capital cities also seem to spend relatively less, and get worse outcomes, on things like education, public welfare, and health care.

Americans' cash-carrying habits

Quick, how much cash is in your wallet? If you’re like the average American, barely enough for a couple of movie tickets: The median consumer carries just $22.

A handful of people roll bigger. Roughly one in five people carry more than $100. One in twenty carry a pickpocket’s dream—$100 bills—according to a new study by Claire Greene and Scott Schuh of the Federal Reserve Bank of Boston. ...

The amount of cash in circulation keeps rising. There’s $1.2 trillion in cash outside banks, up 20 percent since 2011. Use of credit and debit cards is growing, too, but they’re mostly taking over where checks left off. Cash is still used for 40 percent of all purchases, and from 2003 to 2012 the amount of cash pulled from ATMs rose 32 percent faster than inflation. ...
In fact, people who carry around lots of cash aren't that different from anyone else, with one important distinction: They make more money. Consumers who make more than $75,000 are about 50 percent more likely to be carrying around $100 than those who make less than $35,000. That might not seem surprising—more money in the paycheck means more in the wallet—but it undercuts the idea that wads of cash are mainly for poor people who don’t have access to banks or credit cards. In fact, holders of more than $100 were more likely to have a credit card, though they tended to pay it off every month. They were also more likely to be older than 55 and have more than a high school education. Beyond those, the study concluded, “other demographic factors are not statistically significant.”

Most people use cash only to buy small things, and people with lots of cash are no exception. When spending their $100 bills, they’re usually asking a clerk to make change. The Boston Fed study tracked daily spending and found that 78 percent of $100 bills were used on purchases of less than $100. One-third of the time, they were using a $100 bill to buy less than $20 of stuff.

Academic rigor and athletes in the Ivy League

There is a distinct irony in dozens of students, including a large number of athletes, cheating in a course on sports ethics.

That's the situation at Dartmouth College, where 64 students were accused of cheating in a course called "Sports, Ethics, and Religion." ...

Dartmouth religion professor Randall Balmer has said he initially designed the course to help student-athletes who may have trouble keeping up with the workload at the Ivy League college. Close to 70% of the 272 students enrolled in "Sports, Ethics, and Religion" last semester were Dartmouth varsity athletes, The Dartmouth reports, including more than half of the football, men's hockey, and men's basketball teams.
--Peter Jacobs, Business Insider, on not quite a fake UNC class

“The Structure of Networks,” widely known by undergraduates to be one of Yale’s most popular and least rigorous courses, has been capped and will now include a final exam this semester.

Last spring, more than 500 students took the course, which currently has a workload rating of 1.6/5.0 on CourseTable. ...

“Last year, at least 80 percent of the class received an A,” [professor Ronald Coifman] said. ...

Varsity hockey player Henry Hart ’18 said many athletes take “Structure of Networks” because of its reputation on campus.

“I’m in an all-athlete group chat from a fall economics course, and it blew up about ‘Structure of Networks,’ which is supposed to be a good fit for athletes because of its low rigor,” he said. “It seems like it is a class that doesn’t require a lot of work and lets you focus on other things.”
--David Shimer, Yale Daily News, on not quite a fake UNC class 2

Harvard would not say how many students had been disciplined for cheating on a take-home final exam given last May in a government class, but the university’s statements indicated that the number forced out was around 70. The class had 279 students, and Harvard administrators said last summer that “nearly half” were suspected of cheating and would have their cases reviewed by the Administrative Board. On Friday, a Harvard dean, Michael D. Smith, wrote in a letter to faculty members and students that, of those cases, “somewhat more than half” had resulted in a student’s being required to withdraw. ...

It was a heavy blow to sports programs, because the class drew a large number of varsity athletes, some of them on the basketball team.
--Richard Perez-Peña, NYT, on an athlete-heavy Harvard class

Trevor Nash, a Harvard sophomore from the Atlanta area, said the initial reaction on campus was shock that as many as 125 students in a 279-person class with a reputation for favorable grading and a light workload — Government 1310: Introduction to Congress — were being investigated for cheating on a take-home final exam last semester. ...

The news could reignite a contentious decades-old debate about athletes and academic integrity in the Ivy League. Eleven years ago, the publication of the book “The Game of Life: College Sports and Educational Values,” by the former Princeton president William Bowen and James Shulman of the Mellon Foundation, used a vast database on the academic credentials, grades and majors of 90,000 students from 30 elite universities and colleges to depict an athletic culture that significantly influenced campus ethos.

Among the book’s messages was that today’s athletes at elite institutions enter college less academically prepared and with decidedly different goals and values than their classmates.

How to make yourself fall in love with anyone

More than 20 years ago, the psychologist Arthur Aron succeeded in making two strangers fall in love in his laboratory. Last summer, I applied his technique in my own life, which is how I found myself standing on a bridge at midnight, staring into a man’s eyes for exactly four minutes. ...

I explained the study to my university acquaintance. A heterosexual man and woman enter the lab through separate doors. They sit face to face and answer a series of increasingly personal questions. Then they stare silently into each other’s eyes for four minutes. The most tantalizing detail: Six months later, two participants were married. They invited the entire lab to the ceremony.

“Let’s try it,” he said. ...

I Googled Dr. Aron’s questions; there are 36. We spent the next two hours passing my iPhone across the table, alternately posing each question.

They began innocuously: “Would you like to be famous? In what way?” And “When did you last sing to yourself? To someone else?”

But they quickly became probing. ...

With us, because the level of vulnerability increased gradually, I didn’t notice we had entered intimate territory until we were already there, a process that can typically take weeks or months. ...

We all have a narrative of ourselves that we offer up to strangers and acquaintances, but Dr. Aron’s questions make it impossible to rely on that narrative. Ours was the kind of accelerated intimacy I remembered from summer camp, staying up all night with a new friend, exchanging the details of our short lives. At 13, away from home for the first time, it felt natural to get to know someone quickly. But rarely does adult life present us with such circumstances.

The moments I found most uncomfortable were not when I had to make confessions about myself, but had to venture opinions about my partner. For example: “Alternate sharing something you consider a positive characteristic of your partner, a total of five items” (Question 22), and “Tell your partner what you like about them; be very honest this time saying things you might not say to someone you’ve just met” (Question 28).

It’s astounding, really, to hear what someone admires in you. I don’t know why we don’t go around thoughtfully complimenting one another all the time. ...

We finished at midnight, taking far longer than the 90 minutes for the original study. Looking around the bar, I felt as if I had just woken up. “That wasn’t so bad,” I said. “Definitely less uncomfortable than the staring into each other’s eyes part would be.”

He hesitated and asked. “Do you think we should do that, too?”

“Here?” I looked around the bar. It seemed too weird, too public.

“We could stand on the bridge,” he said, turning toward the window. ...

You’re probably wondering if he and I fell in love. ...

How basketball is played in the age of analytics

When Daryl Morey [general manager of the Houston Rockets], the mad scientist of analytics, landed Harden in the trade of the decade, he not only got the superstar he coveted, he also acquired the perfect instrument for his basketball laboratory. ...

By now, everyone knows that the Rockets’ offensive philosophy is built around 3s and paint shots; they avoid the midrange the same way Gwyneth Paltrow avoids Quiznos. As this chart shows, they invest heavily around the hoop and behind the 3-point line.

For Houston, even a below-average 3-pointer or paint shot is a better investment than a good shot in Kobe and Byron Scott’s hairy midrange neighborhood. As a result, the team scores a minuscule 6.2 percent of its points in the midrange, and is happy to sacrifice efficiency in its favorite spaces in favor of volume. While Bryant and Scott turn a blind eye toward the newfangled ways of the NBA, Morey and Harden bask in their glow.

A cursory glance at Houston’s shot chart seems to suggest that the Rockets are an inefficient jump-shooting team. That’s technically true, but it’s misleading. Being slightly “inefficient” within an extremely efficient area, it turns out, is better than being efficient inside an inefficient area. Thanks to their lopsided shot distribution, the Rockets remain among the NBA’s top 10 most efficient jump-shooting outfits. ...

The NBA has legislated this brave new hoops world into existence — promoting the worth of the 3-point shot and free throws over other forms of scoring.

For those of us who grew up watching Bird, Magic, and Jordan, there’s an increasing dissonance between what we perceive to be dominant basketball and what actually is dominant basketball. Sometimes the two are aligned, but they seem to be increasingly divergent — and perhaps the most tragic analytical realization is that the league’s rapidly growing 3-point economy has inherently downgraded some of the sport’s most aesthetically beautiful skill sets. You can’t be Bernard King or Alex English, bobbing and weaving into space on the elbow or along the baseline, anymore. Hell, it’s hard to even be LaMarcus Aldridge or Al Jefferson. The Chris Boshes and Serge Ibakas of the world, once forever camped out in the post, now stray beyond the arc. That unassuming curved line has forever changed the NBA. For every graying Garnett, Duncan, or Kobe, lugging their 2-point jumpers toward the exit, there’s an upstart Harden or Love hanging out behind the 3-point line.
