1 . Beijing will provide COVID-19 vaccinations (接种疫苗) for certain groups in nursing homes, including the elderly and caregivers, on a voluntary basis to prevent a renewed outbreak at nursing homes during autumn and winter, the local government said.

Those who will receive the vaccines include nursing home kitchen workers, security guards and cleaners, Beijing Daily reported on Friday.

Xing Yinli, director of Jingkangyuan, a nursing home in Fengtai district with about 290 elderly residents (居民), said they have received the document (文件) recently and will strictly follow its guidance.

“It’s our top duty to strengthen prevention and control,” Xing said, adding they have been using methods such as keeping detailed records of resident contacts outside the nursing home, and encouraging online visits for family members.

As to vaccinations, she said they will ask for permission from residents, their family members and workers before giving vaccines.

In late October, Shaoxing, Zhejiang Province carried out an emergency COVID-19 vaccine program, allowing the public to ask for injections (注射) in advance, with key groups first. A similar program was also organized in Jiaxing, Ningbo and Yiwu in Zhejiang.

Nationwide, emergency use of home-grown COVID-19 vaccines was approved in June and launched in late July. China now has four coronavirus candidate vaccines in the third stage clinical trials (临床试验).

The document from Beijing also said nursing homes should conduct nucleic acid testing (核酸检测) every month among kitchen workers and residents who leave the nursing homes to see a doctor. Tests will cover all people in nursing homes considered at high risk if new infections are reported in the city. Besides, routine disinfections (消毒) should be strengthened in kitchens, storerooms and restrooms, it said. The document also recommended non-contact visits from family members.

2 . Ride-sharing services are thought to help to reduce pollution since fewer people use private vehicles and cause carbon dioxide．However, a new study has found that these services result in much more pollution than other kinds of private and public transportation．Ride-sharing trips also draw passengers away from more environmentally-friendly methods of travel, like public transportation, walking or biking, the study found．

Several studies in recent years have suggested that ride-sharing services like Uber and Lyft can worsen traffic problems in cities, which continue to have high rates of private vehicle ownership．

The new study, carried out by the nonprofit group Union of Concerned Scientists, represents an attempt to center on how ride-sharing services affect pollution．The research examined the effects of ride-sharing services on seven of America's largest cities．Overall, the researchers reported that ride-sharing trips now “result in about 69 percent more climate pollution on average than the trips they replace”．The study notes that the same passengers could have chosen to travel by bus, train, bike, scooter(小型摩托车)or on foot．

One of the big reasons they give for this result is that ride-sharing vehicles are often driven with no passengers in the car．This happens when drivers are either waiting for rider requests, are on the way to pick up passengers or are driving between pickups．

This situation, known as“deadheading” takes up about 42 percent of the ride-sharing driving activity, the study found．The researchers said that “deadheading” results in about 50 percent more carbon dioxide than one person driving in a private vehicle．

The study urges services like Uber and Lyft to increase the number of electric vehicles on the road and to improve connections to public transportation centers．The two companies already operate businesses that offer electric scooters and bikes and have begun to include public transportation information in their systems．In some cities, they have also promoted vehicle electrification．
