1 . The vaccine (疫苗) news continues to seem very encouraging. Britain started its mass vaccination effort and the U.S. isn’t far behind.
But there is still one dark cloud hanging over the vaccines that many people don’t yet understand.
The vaccines will be much less effective at preventing death and illness in 2021 if they are introduced into a population where the coronavirus is still severe—as is now the case in the U.S.
A vaccine is like a fire hose (消防龙头). A vaccine that’s 95 percent effective, as Moderna’s and Pfizer’s versions appear to be, is a powerful fire hose. But the size of a fire is still a bigger determinant of how much destruction occurs.
At the current level of infection in the U.S. (about 200,000 confirmed new infections per day), a vaccine that is 95 percent effective—distributed at the expected pace—would still leave a terrible toll (伤亡人数) in the six months after it was introduced. Almost 10 million or so Americans would catch the virus, and more than 160,000 would die.
This is far worse than the toll in a different situation where the vaccine was only 50 percent effective but the U.S. had reduced the infection rate to its level in early September (about 35,000 new daily cases). In that case, the death toll in the next six months would be kept to about 60,000.
It’s worth pausing for a moment on this comparison. If the U.S. had maintained its infection rate from September and Moderna and Pfizer had announced this fall that their vaccines were only 50 percent effective, a lot of people would have panicked.
But the reality we have is actually worse.
How could this be? No vaccine can get rid of a pandemic immediately, just as .no fire hose can put out a forest fire. While the vaccine is being distributed, the virus continues to do damage.
There is one positive way to look at this: Measures that reduce the virus’s spread—like mask-wearing, social distancing and rapid-result testing—can still have great consequences. They can save more than 100,000 lives in coming months.

2 . HOW BIG should a business team be?It is an enormously important issue for companies, Teams that are too small may lack the skills required to get the job done:teams that are too big may be impossible to co-ordinate.
Robin Dunbar.an anthropologist at Oxford University,has done a lot of work on primate(灵长目）groups.His argument is that the size of the group is linked to the size of the brain.With their large brains,humans can cope with larger bands,A larger social group has many advantages,allowing for greater protection and specialization.
Whereas 150 is sometimes referred to as the"Dunbar number",the academic himself in fact refers to a range of figures.He observes that humans tend to have five intimate friends,15 or so good friends,around 50 social friends and 150-odd acquaintances.
Running a larger network can be difficult.The armed forces have spent more than 1,000 years experimenting with unit size.A Roman centurion(百天长）oversaw 100.The modern American army company has 180 members.Britain's equivalent numbers 120.These are rough estimates,rather than fixed figures.But it is striking that many group activities seem to be close to a Dunbar number. The Special Air Service of Britain has four-man patrols;when your life depends on it,you need to have absolute trust in your colleagues.As a result,such groups are limited in size.
For much of economic history,work was conducted in small units by peasants,tenant farmers and craftsmen.The coming of powered machinery enabled production at a much larger scale,with workers crowded into factories.These days the rise of the service economy means that workers are no longer concentrated in such large groups.
This may not be a bad thing.It was easy for employees in large factories to regard remote company owners as "them"rather than"us".The modern company may settle on a model with a small group of"core"workers and a larger group of contract workers.The result may be more united within the core staff but the non-core staff may be less well treated.The small core teams may work effectively.The big question will be the effect on morale of those outside those teams.

3 . Did you ever have to say “no” to somebody? Such as a classmate who asks to go to lunch with you? New research suggests that, at least socially, a rejection (拒绝) should not include an apology. In other words, saying you are sorry does not make the person being rejected feel any better. In fact, it might make the rejected person feel worse. That is surprising. Many people consider it to be good manners to say they are sorry when they turn down a request.
Gili Freedman is doing some related research at Dartmouth College. For her research, she asked over 1,000 people to respond to different examples of social rejection. In one example, the researchers asked people for their reaction (反应）after a person named Taylor asked to join a co-worker who went out to lunch every Friday. And Taylor was told “no”. But in some cases, the person rejecting Taylor offered an apology. In other cases, the people doing the rejection did not say they were sorry. People were asked how they would feel if they were being turned down, just as Taylor was. Most said they would be more hurt by a rejection with an apology than a rejection without an apology.
Freedman said the reason is that apologies make people feel like they need to say that the rejection was okay— even when they felt like it was not okay. Rejection without an apology lets them express their feelings of disappointment, hurt or anger more easily. Freedman also said that an apology often makes the person doing the rejection feel better—even as it makes the person being rejected feel worse.
Her research deals only with social communication. A business situation might be very different. “If a manager rejects a job interviewee or a boss must tell an employee that he or she is being fired from a job,” Freedman said, “reactions to apologies may be different.”

4 . Abraham Lincoln turns 200 this year, and he’s beginning to show his age. When his birthday arrives, on February 12, Congress will hold a special joint session in the Capitol’s National Statuary Hall, a wreath (花环) will be laid at the great memorial in Washington, and a webcast will link school classrooms for a "teach-in" honoring his memory.
Admirable as they are, though, the events will strike many of us Lincoln fans as inadequate, even halfhearted — and another sign that our appreciation for the 16th president and his towering achievements is slipping away. And you don’t have to be a Lincoln enthusiast to believe that this is something we can’t afford to lose.
Compare this year’s celebration with the Lincoln centennial, in 1909. That year, Lincoln’s likeness made its debut on the penny, thanks to approval from the U. S. Secretary of the Treasury. Communities. and civic associations in every comer of the country erupted in parades, concerts, balls, lectures, and military displays. We still feel the effects today: The momentum unloosed in 1909 led to the Lincoln Memorial, opened in 1922, and the Lincoln Highway, the first paved transcontinental thoroughfare (大道) .
The celebrants in 1909 had a few inspirations we lack today. Lincoln’s presidency was still a living memory for countless Americans. In 2009 we are farther in time from the end of the Second World War than they were from the Civil War; families still felt the loss of loved ones from that awful national trauma (创伤) .
But Americans in 1909 had something more: an unembarrassed appreciation for heroes and an acute sense of the way that even long-dead historical figures press in on the present and make us who we are.
One story will illustrate what I’m talking about.
In 2003 a group of local citizens arranged to place a statue of Lincoln in Richmond, Virginia, former capital of the Confederacy (南方联邦). The idea touched off a firestorm of controversy. The Sons of Confederate Veterans held a public conference of carefully selected scholars to “reassess” the legacy of Lincoln. The verdict — no surprise — was negative: Lincoln was labeled everything from a racist totalitarian to a teller of dirty jokes.
I covered the conference as a reporter, but what really unnerved me was a counter-conference of scholars to refute the earlier one. These scholars drew a picture of Lincoln that only our touchy-feely age could recall. The man who oversaw the most savage war in our history was described — by his admirers, remember — as “nonjudgmental,” “unmoralistic,” “comfortable with ambiguity (模棱两可) .”
I felt the way a friend of mine felt as we later watched the unveiling of the Richmond statue in a subdued (征服) ceremony: “But he’s so small!”
The statue in Richmond was indeed small; like nearly every Lincoln statue put up in the past half century, it was life-size and was placed at ground level, a conscious rejection of the heroic — approachable and human, yes, but not something to look up to.
The Richmond episode taught me that Americans have lost the language to explain Lincoln’s greatness even to ourselves. Earlier generations said they wanted their children to be like Lincoln: principled, kind, compassionate, resolute. Today we want Lincoln to be like us.
“This helps to explain the long string of recent books in which writers have presented a Lincoln made after their own image. We’ve had Lincoln as humorist and Lincoln as manic-depressive, Lincoln the business sage, the conservative Lincoln and the liberal Lincoln, the emancipator and the racist, the stoic philosopher, the Christian, the atheist (无神论者) — Lincoln over easy (两面煎的) and Lincoln scrambled (把…搅乱) .
What’s often missing, though, is the timeless Lincoln, the Lincoln whom all generations, our own no less than that of 1909, can lay claim to. Lucky for us, those memorializers from a century ago — and, through them, Lincoln himself — have left us a hint of where to find him. The Lincoln Memorial is the most visited of our presidential monuments. Here is where we find the Lincoln who endures: in the words he left us, defining the country we’ve inherited. Here is the Lincoln who can be endlessly renewed and who, 200 years after his birth, retains the power to renew us.
