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 李宇嘉:房价“内生性”上涨驱动政策调整 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.

我没有看到太多迹象表明,“合弄制”(Holacracy)等激进的“无管理者”模式将会普及。但会有越来越多的公司意识到,如果他们不断地尝试创新——就像初创公司那样——他们将比老派的官僚制度和精英管理制度更加灵活和果断。

美国公司高管的薪酬不断上升,收入差距越拉越大。在这种情况下,看到一位不光关心自身收入的CEO不禁让人眼前一亮。9月份,联想首席执行官杨元庆宣布,他将连续第二年和大约1万名联想员工分享他的奖金,数额至少为300万美元。他做出这个慷慨决定的原因是这家个人电脑制造商的年度销售额创下了历史新高。据彭博新闻(Bloomberg News)报道,参与“分成”的联想员工获得的奖金大约相当于中国普通城镇就业者一个月的收入。

Less than an hour ago the official manufacturing PMI for November came in at 49.6, the fourth consecutive month of contraction and below the 49.8 reading economists were looking for. Analysts at ANZ said, in relation to that PMI series:“With soft growth momentum and deflation pressures creeping up, we expect the authorities to further ease monetary policy and continue to implement an expansionary fiscal policy in order to prevent further slowdown of the economy in 2016.”

“Selling out!” “Pandering to the Americans!” The cries went up immediately when the official selection was announced. The list of directors crossing over to make films in English was a long one including the Italians Matteo Garrone and Paolo Sorrentino, Yorgos Lanthimos of Greece, Norway's Joachim Trier and even Guillaume Nicloux of France, a country whose cultural establishment is highly sensitive to the creeping Anglophone menace. The argument goes that Cannes is supposed to be a haven for world cinema; for English, there is Hollywood. But does it really matter? Films at Cannes in languages other than French or English play with subtitles in both languages – and that's a lot of text to deal with.

3. 需求弹性。解决价格低迷的方法就是低价。这是老生常谈,而且适用于供需两个方面。超低的原油价格会刺激需求复苏吗?某些国家对石油市场控制较严,低油价可能不会延伸到零售领域。印尼等国已经取消成品油补贴,这有利于国家财政,但消费者得到的实惠将减少。不过,美国汽油价格已跌破每加仑2.40美元,与2014年中期相比,降幅超过了35%。而此番降价已带动汽油消费的攀升。2014年底,美国汽油日消费量创2007年以来新高。低价可以提升需求,而需求的增长则可带动油价反弹。

In early December, authorities announced that market circuit breakers would be introduced become effective from January 1 in an effort to limit the volatility seen during the savage, summer sell-off from June.
