外星人的问候？加拿大发现了15亿光年的重复无线电波_我的网站

A |     Europe’s leading hotelier Accor - a French international hospitality business with billions in revenue and more than 5,100 hotels - is now beginning “trials” to hire people with no experience in the hotel industry, the company’s chief executive Sebastien Bazin said, as it struggles to fill at least 35,000 vacancies.,“We tried in Lyon and Bordeaux 10 days ago and this weekend we're having people interviewed with no CV, no previous job experience and they are hired within 24 hours," Bazin said.,Since underpaid workers left the company, Accor is now filling those positions with those who are desperate for work such as students and/or expats.,Those who are practically hired on the spot by the multi-billion dollar company are trained in only six hours and are forced to learn on the job. The company will also limit their contact with customers as they struggle with staffing.,"It's students, people coming from North Africa," Bazin said, "and basically closing restaurants for lunch or [opening them] only five days a week. There's no other solution.",Some hoteliers will have to increase pay to find the help they need this tourist season. Spain’s tourism sector supported 13.5 percent of their workforce in 2018 - before the pandemic - and accounted for 11.8 percent of their gross domestic product in 2017. But Spain’s catering industry is at present short some 200,000 workers, and Portugal is fighting to increase staff at their hotels to keep pace with increasing demand.,"Many employees have decided to move to other sectors, so we are starting an industry from scratch and we have to fight for talent," said Gabriel Escarrer, chief executive of Spanish hotel group Melia which, along with other hospitality businesses, is reportedly offering higher wages than previously, health insurance, and free accommodation - though that last perk could be more a reflection of the shortage of housing near resorts.,However, hoteliers such as Hotel Mundial - located in Lisbon, Portugal - are facing the far from ideal decision of cutting services if they can’t find staff, and those who employ students will have to juggle rotas to accommodate their schedules.,“During the week we can't open because we have no hands - they are studying,” said Jose Carlos, who owns a bar in Madrid called Tabanco de Jerez.,Spain's hospitality industry is now paying 60 percent more than it did last year, on average, in an attempt to lure workers back to the force - however, those working in the tourism industry are still among the lowest-paid workers.,"Half of it is we've been blind, we've been not paying attention to a lot of people and probably underpaying some people for too long as well," said Bazin, who is worried his company won’t have enough staff when the summer rush, which is the height of the tourist season - arrives. "So it's a wake-up call.",One of the best documented reasons for people leaving their job during 'The Great Resignation' was because they were being paid too little. Another reason was the lack of professional advancement within the industry.,Other reasons people quit in 2021 included: feeling disrespected, lack of flexibility in scheduling, and a lack of benefits such as healthcare and paid holiday, according to a Pew Research Center survey. That same survey found that those who quit their job were able to find new places of employment that offered them better pay and more opportunities.。加拿大天文望远镜在两个月内捕捉到13次快速的无线风暴，其中包括15亿光年外异常重复的无线电波。科学家们说，他们不能排除电波来自外星航天器的可能性。这项研究现已发表在《自然》杂志上。报道称，13次快速无线风暴中的一次非常罕见，它来自15亿光年之外，是第二次发现重复性无线电波。以前，研究人员用不同的望远镜捕捉相同的波。研究人员说，他们通过加拿大氢强度测绘实验射电望远镜发现了电波，该望远镜由4个100米长的半圆柱形天线组成，去年发射，在发射后不久检测到13次射电爆发，包括重复波。有许多理论可以解释这些宇宙波的起源。例如，这些波可能来自具有强磁场的中子星，或者两个中子星可能合并在一起。

B | 除了这些理论之外，一些观察家认为这些波实际上来自某种外星航天器。
