During the COVID-19 pandemic, technologies are playing a crucial role in keeping our society functional in a time of lockdowns and quarantines（封锁和隔离）. And remote work may have a long-lasting impact beyond COVID-19.

Many companies have asked employees to work from home. Remote work is enabled by technologies including virtual private networks（VPNs）, voice over internet protocols'（VoIPs）, virtual meetings, cloud technology, work collaboration tools and even facial recognition technologies that enable a person to appear before a virtual background to preserve the privacy of the home. In addition to preventing the spread of viruses, remote work also saves commute time and provides more flexibility.

Yet remote work also imposes challenges to employers and employees. Information security, privacy and timely tech support can be big issues. Remote work can also complicate labor law issues, such as those associated with providing a safe work environment and income tax issues. Employees may experience loneliness and lack of work-life balance. If remote work becomes more common after the COVID-19 pandemic, employers may decide to reduce rents and hire people from regions with cheaper labor costs.

Laws and regulations must be updated to accommodate remote work, and further psychological studies need to be conducted to understand the effect of remote work on people.

Further, not all jobs can be done from home, which creates disparity. According to the US Bureau of Labor Statistics, about 25% of wage and salary workers worked from home at least occasionally from 2017 to 2018. Workers with college educations are at least five times more likely to have jobs that allow them to work from home compared with people with high school diplomas. Some professions, such as medical services and manufacturing, may not have the option at all. Policies with respect to data flows and taxation would need to be adjusted should the volume of cross-border digital services rise significantly.

People often call music a universal language, but do certain songs really cause the same mental images in our minds? Scientists at Princeton find that while music absolutely can stimulate(激发)similar mental experiences, the results also strongly suggest culture is a major factor.

A total of 622 people took part in the study. All of the volunteers came from one of three locations: two suburban college towns in the US (one in Arkansas and the other in Michigan), or the rural Chinese village of Dimen. It’s worth noting that the main language in Dimen is Dong, a tonal language unrelated to the official language of China. Locals there have little contact with Western media or culture at all. All participants listened to the exact same 32 “musical stimuli”— which were 60-second cuts of instrumental music. Half of these pieces came from Western music while the rest came from Chinese music.

After hearing, researchers asked the groups about the images they saw in their heads while listening. Incredibly, people from Arkansas and Michigan often described very similar stories, even using the exact same words frequently. Dimen listeners, on the other hand, envisioned stories that were similar to each other but quite different from the American listeners. More specifically, one track led t o Americans seeing a cowboy in the hot desert surveying an empty town. Meanwhile, Chinese participants imagined a man in ancient times reflecting on the loss of a loved one.

“There’s something about the results that’s really surprising, especially because people encounter music in 2022 often in a solitary way, over headphones. But it turns out, it’s still a shared experience, almost like a shred dream, although not universally shared, ”says Elizabeth Margulis, the study author.

The results paint a more complex picture of music’s power. Music can generate remarkably similar stories in listeners’ minds, but it depends on a common set of cultural experiences. So while we imagine music can bring people together, the opposite can also be true-it can distinguish between sets of people with a different background or culture.
