【推荐1】Ever fought with a problem? Picked up a new skill? Encountered a difficult concept? The language of learning is full of references to parts of the body outside the brain. Perhaps that’s because these phrases suggest something deeper. Researchers are detecting that learning is easier, quicker and more long-lasting if it involves the body.

“In the past, people have argued that as we grow, we become more able to think abstractly (抽象地),” says Andrew Manches, a psychologist at the University of Edinburgh in the UK. Conventional (传统的) thinking might suggest that teachers should help prevent children from using body gestures to prepare them for the adult world. But in truth, the physical world never really leaves our thinking. For example, when we process verbs such as lick, kick and pick, medical scanners show that the parts of our brain that control the muscles in our face, legs and hands, respectively, light up with activity.

Science is beginning to back up the idea that actions really might speak louder than words in the classroom. Spencer Kelly, a psychologist at Colgate University in New York, has found that people spend three times as much time gesturing when they think the message they get across is remarkably important, suggesting that even if only at the subconscious (潜意识的) level, we appreciate the communicative value of our body language. Kelly has also found evidence that a teacher is more appealing to students when he or she uses arm and hand movements to stress points.

Also, some studies indicate that young children obtain more if their teacher uses gestures when explaining a concept. Meanwhile, Sunsan Wagner Cook, a psychologist at the University of Iowa in Iowa City, has found that children pick up new concepts more effectively, if they are taught to mirror and repeat gestures their teacher uses.

【推荐3】Accents are an important part of our identity. An accent gives clues about who we are, and the community we belong to or wish to belong to.     1    

What is the difference between accents and pronunciation?

Accents are about localized ways of speaking a language. A French person may speak English flawlessly (完美无瑕地), just with a French accent.     2     However, pronunciation is something that — as a learner— you can get right or wrong. If your pronunciation is correct, you can communicate effectively with others whatever your accent is.

    3    

If you think back historically people were much more localized with generation after generation of families living in the same small villages and few people traveled out of that area during their lifetimes. So over many generations differences in accent emerged and became very distinct to particular areas. Mountainous villages that are not easily accessible often develop very strong and distinctive accents.

How important is it to get an accent right?

If you’re moving to a certain part of a country, you might want to integrate better with your new community.     4     That’s because it shows a sense of belonging to the community you are trying to fit in with.

How to improve your accent?

    5     And then learners should consider which sounds exist in the language you’re learning and then spend some time in front of the mirror practicing moving your tongue and mouth to get those new and different sounds. And learners should be aware of stress and tone, which can sometimes even change the meaning of words.

【推荐1】The United States is one of the world’s wealthiest countries. Despite this, many Americans are not even getting enough to eat. In fact, around 37 million Americans struggle just to put healthy food, or any food at all, on the table every day.

One might think that a food shortage is happening in America, but this is not the case. There is more than sufficient food for everyone. Unfortunately, 40% of food is wasted every day. There are many different ways food is wasted: farmers only pick the best-looking crops, deliveries aren’t made on time, supermarkets throw out extra products, customers buy more than they need, and so on. The highest level of wastage tends to happen in the richest communities.

Meanwhile, people who live in poor or rural areas often have little or no access to food. These areas are called “food deserts”. They have fewer supermarkets, and the only food options that they can afford are often unhealthy ones. Healthy foods such as fresh fruits and vegetables may be impossible to find. Sadly, 12. 8% of the American population live in food deserts.

What can we do to help those who don’t have enough food? Shirley and Annie Zhu came up with a solution. In 2017, when Hurricane Harvey destroyed over 100,000 homes in their city, Houston, the sisters got involved. While helping to clear water from a flooded supermarket, they saw a huge amount of food being wasted. At the same time, thousands of people in the city didn’t have enough to eat.

The girls were only 15 when they set up Fresh Hub with 10 of their classmates. They created an app which could be used by residents to find out whether fresh food was available. Then they contacted local farmers and supermarkets to ask for their extra food.

At first, they found that people didn't take them seriously because they were so young. They decided to work with Second Servings, a local organization that had been providing food to food deserts around the city. The owner of Second Servings, Barbara Bronstein, was impressed with the twins and introduced them to several food providers. To date, Fresh Hub has delivered more than 15,000 pounds of food to people in need.

【推荐2】In a video from Visit Iceland, a crew is seen working on making a horse-sized keyboard out of massive blocks of wood. The keyboard is then put outside against the gorgeous scenery for the typing horses to reply to emails. Unsurprisingly, the replies are nonsense, with examples listed as “bpnisi. // hihaihf＝. sf”. “OutHorse Your Email” is Iceland’s latest stunt (噱头) to promote tourism. Visitors can choose a trained horse to type responses to their work emails when they are on holiday.

Due to the pandemic, many workers have transitioned to remote working, finding that the lines between their work and personal lives have become blurred. A survey conducted by Visit Iceland revealed that 59% of people globally now feel as if their boss, colleagues, and customers expect them to reply when on holiday and 41% of people check their work emails between one and four times a day when on holiday. That’s why Iceland is assigning emails to its horses, asking them to make replies.

“When visitors travel to Iceland, we want them to fully experience everything our nation has to offer, from breathtaking surroundings to endless landscapes," said the head of Visit Iceland. "Our OutHorse Your Email service lets them do just that. With our world-first service, we hope to appeal to people to disconnect and take a well-deserved, uninterrupted break.”

Since “OutHorse Your Email” service was launched, it has got a lot of attention from the Internet. “Is it a ridiculous tourism stunt? Sure. But it indeed encourages me to enjoy my trip wholeheartedly,” said Thom Dunn, an online user from Canada. Hunter Boyce from the USA also made a comment, “The service sounds interesting, but I don’t want to drive my boss mad or be fired.”

【推荐3】Pricing is managers’ biggest marketing headache. It’s where they feel the most pressure to perform and the least certain that they are doing a good job. All successful pricing efforts share two qualities: The policy combines well with the company’s overall marketing strategy, and the process is well-organized as a whole.

A company’s pricing policy sends a message to the market—it gives customers an important sense of a company’s philosophy. Consider Saturn Corporation (a wholly owned company of General Motors). Saturn wants to let consumers know that it is friendly and easy to do business with. Part of this concept is conveyed through initiatives such as inviting customers to the factory to see where the cars are made and sponsoring evenings at the dealership that combine a social event with training on car maintenance. But Saturn’s pricing policy sends a strong message as well. Can a friendly, trusting relationship be established with customers if a salesperson uses all the negotiating tricks in the book to try to separate them from that last $100? Of course not. Saturn has a “no hassle, no haggle” policy which removes the possibility of conflicts between dealer and potential customer. Customers have an easier time buying a car knowing that the next person in the door won’t negotiate a better deal.

Of course, there are typically many participants in the pricing process: Accounting provides cost estimates; marketing communicates the pricing strategy; sales provides specific customer input; production sets supply boundaries; and finance establishes the requirements for the entire company’s financial health. Input from diverse sources is necessary. However, problems arise when the philosophy of wide participation is carried over to the price-setting process without strong coordinating mechanisms (协调机制). For example, if the marketing department sets list prices, the salespeople negotiate discounts in the field, the legal department adjusts prices if necessary to prevent breaking the laws or contractual agreements, and the people filling orders negotiate price adjustments for delays in shipment, everybody’s best intentions usually end up bringing about less than the best results. In fact, the company may actually lose money on some orders.

【推荐1】Plenty of people hate needles simply because they do not want the discomfort of injection. A new invention could help — for those who are needle-shy, how about taking a pill instead?

Two of the most successful covid-19 vaccines, from Pfizer-BioNTech and Moderna, need to be administered via injections because their active ingredients are fragile molecules of mRNA, which would be quickly destroyed by acids in the stomach if administered orally.

Aware of these challenges, Robert Langer and Giovanni Traverso, engineers at the Massachusetts Institute of Technology (MIT), wondered if it might be possible instead to send mRNA into the stomach inside a protective capsule that is engineered to inject patients from the inside, where they would feel nothing.

The device they invented is the size of a large pill, encased in gelatin (明胶) and shaped like the shell of a tortoise. It carries a needle that is engineered to stick into the lining of the stomach only when the device’s flat section sits level to it. And the needle can then inject its payload painlessly into the stomach wall.

The researchers knew, however, that this trick alone would not be enough for safe passage of the delicate molecules into cells. Naked mRNA is not readily taken up by cells, but needs to be encased inside a protective envelope to gain entry. So, to investigate further, the engineers worked with colleagues at MIT and found three polymers (聚合物) that could carry the mRNA payloads successfully and also support a transfer into living cells.

The engineers loaded these polymer-encased mRNA molecules into their turtle-shell pills, which were then swallowed by six mice. As expected, they subsequently found evidence that the mRNA had transferred successfully into the stomach tissue of all the mice. The researchers then went on to test their technology on pigs, which have stomachs that are very similar to those found in humans. They introduced their turtle-shell pills into three animal sand studied their stomachs a day later. Two showed clear evidence of the mRNA having entered their cells. One did not.

The device shows the potential to get mRNA into the body without the need for an uncomfortable injection in the arm. More work is needed to understand why one trial in the pigs failed to yield results.

【推荐2】Playing games, singing carols (圣诞颂歌) and getting dressed in your best for Christmas lunch are British festive traditions that need to be saved for future generations, a study has found.

The survey of 2,000 people found the festive pleasure that people believe is most in need of saving is playing games as a family, with 33% of those surveyed giving it the nod. Carol singing is close behind on 31%, with making paper chains to decorate the home on 28%.

Popular pursuits also listed as being in need of saving are making Christmas cake, putting decorations up on Christmas Eve, making home-made pies and writing a letter to Santa. The study also found that 64% of British families celebrate with their own family-specific traditions, such as leaving the tree decoration to the children, and 62% of people said the most important element in having a good Christmas is spending time with family.

Dr. Martin Johns from Swansea University, said: “Wearing your ‘best’ clothes and giving fruit and nuts in stockings both have their origins before the Second World War. However, the pre-war tradition of putting a lucky piece of coal in children’s stockings has disappeared.”

Many Christmas traditions are imports from America, but Christmas cards are one that Britain gave to the world. The first Christmas card is widely claimed to date back to 1843, the same year as A Christmas Carol was published by Dickens, but they were actually on sale by the end of the 1820s. The Victorians saw them as luxurious items and bought them individually, choosing specific designs for each friend and relative. Up until the 1960s, cards were delivered on Christmas morning, adding to the specialness of receiving one.

【推荐3】The employees at Helwig Carbon Products in Milwaukee have their own company cafeteria on a site, a rarity it seems more and more these days. But if anyone wants to eat a doughnut (甜甜圈), it’s going to cost twice as much as what they might pay for the sweet at the local grocery store. That’s because Helwig Carbon Products has a wellness program, and it is one of many local companies trying to show employees how to eat healthier.

“We’re really trying to persuade people to eat healthier,” said Cheryl Brah, human resources director at Helwig Carbon Products. “A piece of fruit is 25 cents; a doughnut is $1.50 — and we still have people who buy doughnuts. People complain — but we really try to put our efforts toward the middle-of-the-line people who might lean more toward the wellness side, eventually.”

This effort isn’t just happening at Helwig Carbon. There has been a city-wide movement of 44 local companies who added or evolved their health and wellness programs to their company culture, and because of it Milwaukee is now nationally recognized for a large number of businesses with wellness programs.

It all started several years ago, when a program called Well City Milwaukee teamed up with 44 local businesses that collectively represent a workforce of 130,000 employees. Well City Milwaukee provided healthy practices guidelines for businesses. In exchange, it surveyed the employees to find out what their health needs and risks were and what activities they found interesting. Well City then set a very high bar for companies to meet a lot of expectations to be considered a top wellness program.

Companies needed a commitment from the CEO; to form a wellness team; to collect information from the employees in surveys and health assessments; to come up with an operating plan; to create a supportive environment; to self-evaluate their efforts; and finally, to choose their best approaches. That meant coming up with activities, better nutrition education, and motivational programs like getting people to quit smoking, getting people in for medical self-care and working on stress management.
