原标题：美最新研究：新冠病毒使至少50万人脱离美国劳动力市场根据《华尔街日报》当地时间9月12日报道，最新研究发现，由新冠病毒引起的疾病已使美国劳动力减少了约50万人，如果继续保持目前的病毒感染率，美国劳动力将会持续被削减。根据研究，在新冠疫情期间，数百万人因各种原因离开了劳动力市场，包括退休、缺乏儿童保育和对新冠疫情的恐惧等。    PHILADELPHIA -- A former Philadelphia police officer has been sentenced to 15 to 40 years in state prison after pleading guilty to sexually assaulting women and girls — often while in uniform and in the back of his police vehicle.Patrick Heron, 54, entered the pleas Friday after reaching an agreement with prosecutors in advance of a trial on more than 200 counts that included child sex assault, child pornography, kidnapping and related offenses, The Philadelphia Inquirer reported.Jane Roh, spokesperson for the district attorney’s office, said victims who are now spared the trauma of a trial welcomed the guilty plea. Defense attorney Anthony List also said he hoped the plea would spare the victims the anguish of having to testify, and added “hopefully everyone can move on.”Heron, who retired from the force in 2019, was initially accused last year of posing as an active officer to lure girls. Investigators said they later found photos and videos indicating predatory behavior spanning years and including dozens of often vulnerable young women and girls including those who had run away, been arrested or struggled with addiction.Lyandra Retacco, chief of the prosecutors' special investigations unit, said the crimes occurred from 2005 through last year, and Heron met many victims while on the force. She said investigators have identified 48 victims, though many of their identities remain unknown, and more likely haven't come forward.。8月份劳动力总规模达到1.647亿人，首次超过2020年2月疫情前水平。但该研究作者、斯坦福经济学家戈皮·沙·戈达以及麻省理工学院经济学家埃文·J·索尔塔斯表示，如果没有疫情影响，劳动力总人数预计将增加50万人。

二 | 若美国持续保持当下新冠感染水平，预计将损失更多劳动力。部分经济学家认为，美国劳动力的缓慢复苏以及对工人的高需求是美国经济面临的主要挑战之一，这限制了雇主提供商品和服务的能力，并加剧了价格压力。
