5 . Just back from a job interview? Before breathing a sigh of relief, there’s one more thing to do: write a thank-you letter.     1     The sooner you do it, the better. This last step should be regarded as part of your job search process for every interview in which you take part.

At the conclusion of your interview, be sure to have the contact information of all the people who have interviewed you.     2    

Sending a thank-you letter to a potential employer, which costs you little time, will not guarantee a job offer, but it will give you an edge if the competition is tight.

    3     Just as you wouldn’t visit someone’s home and leave without expressing gratitude (感谢), don’t leave an interview without saying thank-you to the interviewer. Being polite and professional is important when communicating with potential employers.

Another significant reason to send a thank-you letter is that it is an opportunity — perhaps your only one — to follow up after your interview.     4     It may feel awkward to say those words out loud during the interview, but it’s much easier to type them.

Your thank-you note can make up for something important. No matter how prepared you are, the stress of the interview may cause a brief lapse of memory.     5     It also allows you to repeat something you want the interviewer to have in mind as they make the hiring decision.

6 . Children whose fathers make time to play with them from a very young age may find it easier control their behavior as they grow up, research suggests.

To understand what effect playtime with dads can have on kids, the researchers analyzed nearly 80 studies, undertaken between 1977 and 2017 — most of them in Europe or North America. They were most interested in understanding how playtime between dads and their kids translated into kids’ development.

On average, they found that most fathers play with their children every day. Even with the smallest children, however, father-child play tends to be more physical. With babies, that may simply mean picking them up or helping them to gently raise their arms and legs; with toddlers (学步儿童), physical play includes rough-and-tumble activities, like chasing (追赶) game.

The study found that the kids who enjoyed playtime with their fathers were less likely to lose their tempers with other kids and exhibited better behavior. The researchers found that this was beneficial kids’ development, as this type of play was associated with better self-control and behavioral outcomes.

“Physical play creates fun, exciting situations in which children have to apply self-regulation.” said Ramchandani, Professor at the University of Cambridge. “They learn from their mistakes and the reactions they get from others. If they react the wrong way, they might get scolded, but it’s not the end of the world — and next time they might remember to behave differently.”

However, the researchers stress that children who only live with their mothers need not be at a disadvantage. “Different parents may have slightly different inclinations when it comes to playing with children, but part of being a parent is stepping outside your comfort zone. Children are likely to benefit most if they are given different ways to play and interact,” said Ramchandani.

7 . A company called Loon is partnering with Telkom Kenya, Kenya’s third-largest cell service company. The company is using balloons to deliver the Internet to people across Kenya.

Loon’s balloons are basically floating cell towers. And they are massive—each is about as big as a tennis court. The balloons float about 20 kilometers above the Earth. The huge plastic balloons can float for up to 100 days, running on solar power. Loon is using 35 balloons to make the Internet easily accessible around 50,000 square kilometers of Kenya.

Delivering Internet via balloons seems fragile. In fact, Internet service delivery from the stratosphere (平流层) is highly effective. Rather than fight against the wind, the balloon teaches itself to find a favorable wind current. At altitude, network coverage footprints can be more widespread, and coverage can be shifted as demand changes. In addition, there’s less ground-based engineering construction; developers can avoid more trouble in laying cables or wires. More importantly, service interruptions are possibly more controllable. A provider doesn’t have to trace faults through remote ground infrastructure (设施). Backup balloons could be staged, waiting to be placed into service.

Now some Kenyans are using the service to watch videos, look at websites, and make video and voice calls. Others beef a bit, saying that Loon’s service covers areas of Kenya that already have some cell phone service, instead of remote, poorly-connected areas in the north. Loon says it will speed up the process. After Kenya, Loon plans to use its balloons in other parts of the world. Many people will be watching Loon’s Kenya project carefully to see if it succeeds in a way that could be repeated in other countries.

Before this, Loon’s balloons were used mainly to provide Internet service to disaster victims in Puerto Rico, following Hurricane Maria, and in Peru following an 8.0 magnitude earthquake.

8 . A Canadian named Justin was fishing during a recent rafting (漂流) trip on the Red Deer and South Saskatchewan Rivers when he heard something noisy in the water. He saw a nose barely above the water. Unable to tell what kind of animal it was in the dark and water, Justin reached for the animal but ended up falling out of his raft in the freezing cold river. Luckily, Justin was somehow able to locate the animal—a coyote pup (郊狼崽)—in the water and catch his raft before it floated away for good.

Unfortunately, when Justin brought the animal back to his raft, the baby coyote was unconscious and didn’t seem to be breathing. The pup was lucky again. Justin had experience with CPR and pushed on its belly in hopes of revival(复活). After a few pushes, water came out of the coyote’s nose and he was breathing again! Justin and his new friend were both wet through so they made their way back to land, where Justin made a fire and tried to warm the little guy up.

During his 10-day rafting trip, Justin brought the coyote he named YipYip along for the ride, and kept the coyote with him the entire time. The little pup would eat with Justin and sleep in his backpack. Justin wrapped him in his jacket when it was cold. When Justin was able to get Internet service, he called his wife for advice. The couple eventually got in touch with the Wildlife Rehabilitation Society of Saskatchewan (WRSOS).

According to WRSOS president Bonnie Dell, YipYip quickly befriended the other adopted coyote pups. “He is wilding up and has a healthy fear of humans now. He will not be returned to the wild until he is old enough,” Dell said, adding that YipYip would have died without Justin’s efforts.
