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 钢铁业产能逆调控增长 “汰小上大”投资井喷 the quarantine period, and its counterpart organizations do so abroad, all in concert with the World Health Organization.

Funds will becommitted to attract top faculty, build state-of-the-art facilities, andrecruit the very best students. China will lock into a global war forintelligence, education, and skill.

"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.

Canadian border agents are handing people entering Canada a sheet from the Public Health Agency of Canada that instructs them to self-quarantine for 14 days and monitor themselves for any symptoms that might signal COVID-19. Selena Simmons-Duffin/NPR hide caption

《风骚律师》(Better Call Saul),AMC,2月8日播出。这是文斯·吉里根(Vice Gilligan)与彼得·古尔德(Peter Gould)的《绝命毒师》的衍生剧,或许是今年冬天最受期待的新剧了。鲍勃·奥登科克(Bob Odenkirk)饰演狡猾的律师索尔·古德曼(Saul Goodman),剧情设定在《绝命毒师》的故事发生之前,所以布莱恩·克莱斯顿(Bryan Cranston)或亚伦·保罗(Aaron Paul)至多只是客串出演而已。但观众们最喜欢的乔纳森·班克斯(Jonathan Banks)将在里面重现他在《绝命毒师》中的角色——冷静的行动执行者迈克·厄尔曼特劳特(Mike Ehrmantraut)。

例如,佳士得给威尼斯艺术家弗朗西斯科·丰泰巴索(Francesco Fontebasso)在18世纪中叶创作的油画《井边的丽贝卡和埃利泽》(Rebecca and Eliezer at the Well)的最低估价为12万英镑。根据Artnet的数据,在1990年的拍卖会上,这幅令人愉快的洛可可装饰风格的油画是以28.6万英镑购得的。在12月8日的拍卖会上,它仅得到一个电话出价——11.5万英镑(不含佣金),约合17万美元。而投资者们可不认为在购买沃霍尔(Warhol)或巴斯奎特(Basquiat)的作品25年之后会损失约40%。如果一幅早期绘画大师的作品被搁置在交易商的画廊里,想转卖它就更加困难。
Mr Williams’ medium to long-term view is arguably more gloomy than that of Mr Baweja. He believes the 25-30 year period during which growth in global exports far exceeded that of global GDP, represented a “surge of globalisation that has come to an end”. In other words, the current slowdown in trade growth is structural, not cyclical.

A third of British schools rise five places, in contrast to the two-thirds of French schools that drop five or more places.

There are no such circuit breakers in Hong Kong where the H-share index of mainland equities fell less than 4 per cent on unremarkable volumes. One might have expected more of a bloodletting. Mainland retail investors participate in both markets — a function both of Stock Connect and a leaky system — and if you can’t sell what you would like, you sell what you can. Foreign H-share investors too might be presumed sellers, having been the most bearish on China’s economy. Yet yesterday, even as Shanghai opened down a further 3 per cent (before rebounding), Hong Kong’s H shares remained resilient.

补救办法:当我们在做出重大决定时,例如接受(或拒绝)工作邀请时,我们往往会受到信息性偏见的影响。如果我们认为自己做出了正确的选择,就首先会想到那些支持这种想法的信息。但如果我们担心自己犯了错误,我们的潜意识就会增强这种直觉。在做出工作的决定时,如果你习惯性地怀疑自己的能力,这个问题不在于你以前所做的职业选择是否正确,而在于你需要建立自信,相信自己有能力选择让自己满意的职业,并对结果有一定的把握。若要解决这个问题,需要回忆你在做出这个选择时所处的环境和当时你所优先考虑的因素,然后看看现在所处的环境和优先考虑的因素是否发生了变化。此外还要与职业顾问合作,理清工作决策,帮助你增强进入新领域的信心、承担风险和谈判的能力。

达洛伊西奥解释道,自然语言处理有统计学和语义学两种方法,语义学系统试图解析文章的真实含义并对其进行简洁的译介。而统计学系统──设计Summly所采用的方法──无需这一过程;该系统保留词汇和句子的完整性,并通过运算从全文挑选出最具概括力的内容。它将每个句子或词汇进行分类、排序,以便挑出编入摘要的内容。这一过程极依赖数学计算,考量的是频率和分布,而非词语的含义。
