To stop the spread of the coronavirus, health officials have a favorite refrain: After being in a city or region where there have been a lot of COVID-19 cases, spend 14 days in quarantine even if you feel perfectly fine — don't leave your house. Coming from New York? 14-day quarantine. Arriving in Hawaii? 14-day quarantine. Been in Italy or China or Iran recently? 14-day quarantine.

"That's a long-standing public health practice, and it's called 'traveler's quarantine,' " explains Lindsay Wiley, a professor at American University's Washington College of Law. "Fourteen days is not a made-up number here — it's based on what we know so far about COVID-19, and it's possible that over time we'll see that number change as we learn more [about the virus]."

The 14-day rule is widespread because public health agencies around the world work together on these guidelines. In the U.S., the 深度解读:家居行业未来发展的三个突破口 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

"The incubation period varies from virus to virus and sometimes from host to host," says Rachel Graham, a virologist at the University of North Carolina's Gillings School of Global Public Health.

For the virus that causes COVID-19 — its official name is SARS-CoV-2 — researchers have found that the typical incubation period is about five days. About 97% of the people who get infected and develop symptoms will do so within 11 to 12 days, and about 99% will within 14 days.

The Great Recession had devastating effects across the U.S. and few places were as hard hit as Arizona. The state was booming on the strength of its tourism and real estate markets during the 2000s. Median home prices jumped 70% between 2003 and 2006—only Nevada had bigger gains—fueling more building and construction jobs. Monthly unemployment was at 3.5% through much of 2007. But then the bottom fell out. Home prices plummeted more than 50% from their peak and 6% Arizona properties received foreclosure filings in 2009. Unemployment stubbornly remained in double-figures for most of 2009 and 2010 and only Nevada lost a higher percentage of jobs over the last five years. Household incomes declined at the fastest rate in the country since 2008.

The “cool” factor isn’t the only issue. Security and privacy, particularly around the management of consumer data, remain a concern as the tech industry seeks to bring more of our body parts online. As The Economist notes, the glamour of developing sensors and algorithms for wearables is distracting everyone from glaring missing elements, “standards, interoperability, integration and data management” and “intellectual-property rights and regulatory compliance” among them. All this in an environment where paranoia remains over the National Security Administration’s activities.

东道主的对手阿根廷队在此次世界杯中也有很大的机会。一支以梅西为主的队伍都会在最后大放异彩,但是当你在队伍中增添类似塞尔吉奥·阿奎罗(Sergio Aguero)、冈萨罗·伊瓜因(Gonzalo Higuan)和埃泽奎尔·拉维奇(Ezequiel Lavezzi)这样的队员的话,那么它将是这届世界杯上最具有进攻打法的球队了。同理,乌拉圭的进攻三人组——路易斯·苏亚雷斯(Luis Suarez)、埃丁森·卡瓦尼(Edinson Cavani)以及迪亚戈·弗兰(Diegol Forlan)同样拥有同等的实力,能对世界上任何一支球队比赛时进球,不过,他们所在队伍中其他人的实力是否足够强还让人存疑。

The study participants asked to imagine acting out the trait, which is a method of self-imagining, were most successful in remembering the personality traits when questioned about them later. In fact, study participants who engaged in self-imagining were three times as likely to successfully remember a personality trait than participants who didn't use any type of memory device or method. The scientists in charge of the study believe that self-imagining could help individuals in rehabilitation programs, as well as anyone with a memory impairment. However, it's likely that the technique could help just about everyone, even if he or she wasn't currently in a rehabilitation program or diagnosed with memory problems. For example, if you wanted to remember where a friend bought a pair of shoes, you might imagine yourself walking into that store to buy the shoes.
