【推荐2】A study by a team of Nanyang Technological University, Singapore (NTU Singapore) psychologists has found a link between extraverts (外向的人) and their word choices. The finding highlights the need for stronger linguistic indicators to be developed for use in online personality prediction tools, which are being rapidly adopted by companies to improve digital marketing strategies.

Today, marketing companies use predictive algorithms (算法) to help them forecast what consumers want based on their online behaviors. For example, an extravert consumer might be attracted to marketing messages that match their personality, and retail brands could then choose to target such consumers by using more extraverted and creative language to advertise their products. However, personality prediction tools available today that are used by marketing firms are not entirely accurate due to a lack of theoretically sound designs. This may lead to a weakness affecting the performance of the machine learning algorithms. This begs the question—how should we create robust and accurate personality predictions?

The study found a correlation between extraverts and their tendency to use certain categories of words. The results showed a small strength of relationship between extraversion and the use of “positive emotion words” and “social process words.”

Positive emotion words are defined as words that describe a pleasant emotional state, such as “love”, ”happy”, or “blessed”, or that indicate positivity or optimism, such as “beautiful” or “nice”. Social process words include words containing personal pronouns except “I”, and words showing social intentions, such as “meet”, “share” and “talk”.

Moving forward, the NTU research team will investigate the relationship between extraversion and other word categories. They hope their work will provide clarity on the types of words that can help guide the development of more accurate machine learning tools for personality prediction.

Her take on these items, ranging from desk lamps and hair dryers to cooking machines, drew more than 100 replies, unusual for that specific section of the discussion group where 50 replies would normally put the topic in the hot category.

However, the interest shown to what to some may seem like a trifling matter should not really be that surprising given that in China 77 million people live alone. These solo dwellers, aged 20 to 39, are mostly engaged in high-paying jobs in fields like finance, so as a group they have tremendous spending power.

Home appliance makers and sellers are one of the main beneficiaries of the solo economy. Take Little Bears Electric Appliances. It has been expanding and updating its product line to target at the solo market, and half its 40 product categories are now singles-friendly.

A New York University sociology professor, Eric Klinenberg, said in his book Going Solo: The Extraordinary Rise and Surprising Appeal of Living Alone that the single society is becoming hugely powerful and an indicator of social change.

In 2018 and 2019 the Japanese video game Travel Frog became a hit in China. Actually, Travel Frog was a game that seemed to speak directly to those who keep the solo economy ticking. In it, a wayward (任性的) frog has become a baby people are keen on looking after. The frog never interacts with the player, eats alone, reads and does craft work at home and often sets out on journeys, sending postcards to the player letting him or her know its new location. The Travel Frog phenomenon was just one more sign of the increasing importance of the solo economy, with more and more people actively or passively accepting and enjoying their solitude.

Travelling alone is becoming a strong market opportunity. 75% of Ctrip’s self-operated tour groups have opened options for one-person travel, and it plans to develop more innovative products and services tailored to solo travelers.

In entertainment and recreation, too, the solo economy is changing how things work. Minikaraoke booths, self-service photo studios and self-service gyms have popped up on many comers in many cities.

【推荐3】Step aside, blue collar. And white collar, pink collar and green collar. There’s a new collar in town. “New collar” jobs are those that require advanced skills but not necessarily advanced degrees, especially in emerging high-tech fields like artificial intelligence, cybersecurity (网络安全), electric vehicles and robotics.

There are real fears that workers will lose jobs to technology, especially artificial intelligence, in the coming years. But “new collar” optimists think in a more positive way: There are also real opportunities ahead for skilled workers who know how to handle machines.

“Somebody has to program, monitor and maintain those robots,” said Sarah Boisvert, the founder of the New-Collar Network.

Even if millions of high-tech jobs are created in the coming years, the impact on workers who lose jobs may be significant. For many Americans without four-year college degrees, according to census (人口普查) data, the new job market will require training.

Ginni Rometty, a former chief executive of IBM, is believed to have created a “new collar” in 2016. At the time, she said, IBM was having trouble filling cybersecurity jobs, partly because outdated criteria required that candidates have college degrees.

“Due to our high qualifications in these online jobs, we overlooked a large number of qualified and available candidates,” she wrote in an email. “Unless millions of people are trained in the skills employers need now,” she added, “they risk being unemployed even as millions of good-paying jobs go unfilled.”

Christopher M. Cox, a researcher who has written about the new-collar economy, said, “The alternative model of four-year universities is really great.” However, he added that “new collar” may also be a clever term that relieves the anxiety of workers by defining the constantly changing labor market and technology companies as more ideal rather than “terminators (终结者).”
