He has also vandalized the room using a fire extinguisher.The room is isolated away from the rest of the rehabilitation center, so patients there have not been evacuated but are being told to shelter in place.Police have called on the department's Emergency Negotiating Team and a SWAT team to assist with the incident. 1087

Two studies released this week are offering some hope for parents and school districts looking to reopen this month across the country.The studies, one from the United Kingdom and the other from Australia, were published in the journal The Lancet Child & Adolescent Health this week and try to help inform ongoing discussions around reopening schools.A team in Australia was able to look at results from students who remained in class between January and early April.Researchers found even though schools remained open in New South Wales, children and teachers did not contribute significantly to the spread of Covid-19 -- because good contact tracing and control or quarantine strategies.Their data showed that while 27 children or staff at 25 schools and daycares had attended school while infectious with Covid-19, only 18 other people later became infected.That’s an attack rate of 1.2 percent. Overall, the attack rate of child-to-child transmission was 0.3 percent, while the attack rate of adult staff member to another adult staff member was 4.4 percent.“With effective case-contact testing and epidemic management strategies and associated small numbers of attendances while infected, children and teachers did not contribute significantly to COVID-19 transmission via attendance in educational settings,” the Australian team of researchers state in their report.In the British study, researchers looked at models on returning to school with different scenarios, including increased testing, isolation measures for positive cases, and levels of contact tracing.The models the researchers ran assumed that 75 percent of those with positive test results are contacted, provide information for contact tracing and isolate, and that 90 percent of that person’s contacts are reached by contact tracers and asked to isolate.The team assumed between 59 percent and 87percent of symptomatic people in the community would need to get tested at some point during their infection, testing results would be returned in one day, and those asked to isolate would do so for 14 days.Researchers made it clear that these levels would be needed to reopen schools.“However, without these levels of testing and contact tracing, reopening of schools together with gradual relaxing of the lockdown measures are likely to induce a second wave that would peak in December, 2020,” their report stated. “To prevent a second COVID-19 wave, relaxation of physical distancing, including reopening of schools, in the UK must be accompanied by large-scale, population-wide testing of symptomatic individuals and effective tracing of their contacts, followed by isolation of diagnosed individuals.” 2683

Uber's IPO will likely arrive before the end of the decade.CEO Dara Khosrowshahi confirmed on Thursday that the company's "target" is to go public in 2019. The move is a departure from his predecessor, Uber co-founder Travis Kalanick, who had tried to put off an IPO as long as possible."We have all of the disadvantages of being a public company, as far as the spotlight on us, without any of the advantages of being a public company," Khosrowshahi said on stage at the New York Times DealBook Conference in Manhattan."Travis and the whole board now agree that we should just go public," he added.Uber currently has a valuation of billion, which makes it the most highly valued startup in the world. The company has raised more than billion in capital since its founding in 2009.SoftBank, the Japanese conglomerate, has also been in discussions with Uber for a massive private investment expected to total in the billions. Khosrowshahi expressed confidence about getting Uber's entire board on the same page and closing the deal."There's negotiations going on," he said. "They've probably taken longer than they should have, but we're gonna get there."The event marked Khosrowshahi's first extensive interview since taking over as Uber's CEO two months ago. In the conversation, he spoke candidly about his early doubts about the job given Uber's numerous PR crises at the time."It was this media circus that honestly I didn't want any part of," said Khosrowshahi, describing his initial feelings when he received a call about the CEO search. Khosrowshahi was then the CEO of Expedia. A friend, Spotify CEO Daniel Ek, later talked him into taking the opportunity seriously.Before joining the company, Khosrowshahi reviewed the company's financial and legal issues, as well as reading the blog post from a former engineer that rocked Uber with allegations of sexual harassment. However, he did not ask to read a report on the failures of Uber's reckless company culture put together by former U.S. Attorney General Eric Holder."The culture went wrong, and the governance of the company went wrong and the board went in a very bad direction," Khosrowshahi said. "But if the product is good, then if you can bring in good leadership, you can ultimately bring it together."Earlier this week, Khosrowshahi published a new set of "cultural norms" for the company, replacing Uber's "win at all costs" mentality with greater emphasis on corporate responsibility and inclusion. One of the norms: "We do the right thing. Period."But one of the biggest obstacles for Khosrowshahi's turnaround effort at Uber may be Kalanick. The former CEO continues to serve on Uber's board. In late September, Kalanick blindsided the company by using his power to appoint two new board members.Khosrowshahi admitted Kalanick wants to be more a part of the company than he currently is."It's a good relationship, but it comes with balance. What I told Travis very early on is that any new CEO needs space and needs distance from the old CEO," Khosrowshahi said. "I was a little worried about that conversation, but actually he took it very well and he's been very respectful."Khosrowshahi said he does anticipate leaning on Travis for insights on the business at a later date. "Over a period of time," he said, "I would be foolish not to use Travis's incredible genius and his knowledge that really was largely responsible for getting the company to where it is now."  3463

VACAVILLE, Calif. (AP) — A pilot battling fire in central California died after his helicopter crashed as thousands of people in the San Francisco Bay Area were under orders to evacuate Wednesday amid a blistering heat wave now in its second week. Gov. Gavin Newsom blamed the extraordinary weather and thousands of lightning strikes for 367 known fires, including 23 major fires or groups of fires. He said the state has recorded nearly 11,000 lightning strikes in 72 hours. Ash and smoke filled the air over San Francisco, which is surrounded by wildfires burning in multiple counties to the north, east and south. 624

Two US Marine aircraft crashed off the coast of Japan, the US Marine Corps announced Wednesday in a statement.It is believed five individuals were on board a KC-130 and two individuals were in a F/A-18, two US defense officials told CNN. At least one Marine had been rescued just before 6 p.m. ET, according to a Marine Corps spokesman."Search and rescue operations continue for US Marine Corps aircraft that were involved in a mishap off of the coast of Japan around 2:00 am Dec. 6," local time, a statement by the US Marine Corps reads.The planes "had launched from Marine Corps Air Station Iwakuni and were conducting regularly scheduled training when the mishap occurred," according to the statement.The crashes happened approximately 200 miles off the coast of Iwakuni, Japan, a US Marine Corps official tells CNN.The primary mission of a KC-130 is airborne refueling. It is not known at this time if the aircraft was refueling at the time of the crash."The circumstances of the mishap are currently under investigation," the statement said.."Japanese search and rescue aircraft immediately responded to aid in recovery," according to the statement.Wednesday's incident comes on the same day that the Marines released a report on a crash in July 2017, also involving a KC-130 variant that killed 15 Marines and one sailor.That KC-130T crash took place in Leflore County, Mississippi, and the "investigation determined that the aircraft's propeller did not receive proper depot-level maintenance during its last overhaul ... in September 2011, which missed corrosion that may have contributed to the propeller blade" coming loose during the flight and going into the aircraft's fuselage, according to a Marine Corps statement on the investigation. 1759
