During 20 years of working at his family’s supermarket，José Luis - Reig，known as Pep，never gave a thought to the world of academia（学术界）. It was only when visiting the classrooms of universities with his two teenage daughters that he suddenly felt at home among “the atmosphere of learning”.
After school Pep had intended to study biology. Nevertheless，he was called on to help run the family business. When he was at school，he developed a reputation for helping others and so was invited to the local radio，where the presenter said，“You’re like a young psychologist（心理学家）.”
Pep never dreaded making a change. The family business had originally been a sawmill（锯木厂）. But when Pep，then 27，was asked if he wanted to take over，he decided to change the mill into the town’s first supermarket.
One day in the shop，the radio presenter’s comment came back to him. After running the idea past his family，he applied to a university in Palma to study psychology and，at the age of 46，he was accepted.
“I had to get used to being much older than the other students，” he says. “But I ended up helping the others because I’d had more life experience.” Pep came top in his year and impressed his tutors（导师）so much that he was offered a job. Now 52，and still in the job. He adds，“My only regret is not having done it earlier.”
The traditional view used to be that，while making changes in your youth was acceptable，you should then settle on a career and stick to it. But today people in their 50s and 60s are choosing to take on new challenges.

Livestreaming through channels is an increasingly popular way to sell goods online. Someone promotes a product and the duration can be long or short. Viewers can then readily buy it by clicking on a link.
Researchers analysed 99，451 sales cases on a livestream selling platform and matched them with actual sales cases. In terms of duration，that is equal to over 2 million 30 - second television advertisements.
To determine the emotional expression of the salesperson，researchers used two deep learning models：a face detection model and an emotion classification model. The face detection model discovers the presence or absence of a face in a frame（镜头）of a video stream. The emotion classification model then determines the probability that a face is exhibiting any of the six basic human emotions：happiness，sadness，surprise，anger，fear or disgust. For example，smiling signals a high probability of happiness，while a scowl usually points towards anger.
Researchers wanted to see the effect of emotions expressed at different times in the sales cases so they calculated probabilities of each emotion for all 62 million frames in their database. They then combined these probabilities with other possible aspects that might drive sales—such as price and product characteristics—to judge the effect of emotions.
They found that，perhaps unsurprisingly，when salespeople showed more negative emotions，such as anger and disgust，the volume of sales went down. But they also found that a similar thing happened when the salespeople showed high levels of positive emotions，such as happiness or surprise.
A likely explanation，based on their research，is that smiling can be unpleasant because it lacks true feelings and can reduce trust in the seller. A seller’s happiness may be taken as a sign that the seller is gaining interests at the customer’s expenses.
