COVID-19 is 10 times more deadly than swine flu: WHO

GENEVA — The novel coronavirus is 10 times more deadly than swine flu, which caused a global pandemic in 2009, the World Health Organisation said Monday, stressing a vaccine would be necessary to fully halt transmission.

WHO chief Tedros Adhanom Ghebreyesus told a virtual briefing from Geneva that the organisation was constantly learning about the new virus sweeping the globe, which has now killed nearly 115,000 people and infected over 1.8 million.

"We know that COVID-19 spreads fast, and we know that it is deadly, 10 times deadlier than the 2009 flu pandemic," he said.

WHO says 18,500 people died of "swine flu", or H1N1, which was first uncovered in Mexico and the United States in March 2009, but the Lancet medical estimated the toll to be between 151,700 and 575,400.

The Lancet review included estimated deaths in Africa and Southeast Asia that were not accounted for by the WHO.

The outbreak, which was declared a pandemic in June 2009 and considered over by August 2010, turned out to be not as deadly as first feared.

Vaccines were rushed out, but in hindsight, the West, particularly Europe, and the WHO were criticised for overreacting at a time when annual influenza epidemics every year killed between 250,000 and 500,000 people, according to WHO.

Tedros lamented Monday that some countries are seeing a doubling of cases every three to four days, but stressed that if countries were committed to "early case-finding, testing, isolating [and] caring for every case and tracing every contact" they could rein in the virus.

More than half of the planet's population is currently staying home as part of efforts to stem the spread of the virus, but Tedros warned that "our global connectedness means the risk of re-introduction and resurgence of the disease will continue".

He pointed out that while COVID-19 had accelerated quickly, "it decelerates much more slowly."

"In other words, the way down is much slower than the way up," he said, stressing that "control measures must be lifted slowly, and with control. It cannot happen all at once."

"Control measures can only be lifted if the right public health measures are in place, including significant capacity for contact tracing," he said.

Regardless of the efforts put in place, the WHO acknowledged that "ultimately, the development and delivery of a safe and effective vaccine will be needed to fully interrupt transmission".

A vaccine is thought to be at least 12 to 18 months away.

 

Audi A8 L W12: Playing by the dozen

By - Apr 13,2020 - Last updated at Apr 13,2020

The flagship version of Audi’s flagship model, and available only as a special order – depending on market – the current Audi A8 L W12 is set to be the last application of the German manufacturer’s magnificent four-bank 12-cylinder engine, as it focuses on downsizing and efficiency. Ultra smooth and abundant is as indulgent in its delivery and ability, the A8 L W12 is similarly the lost luxurious version on offer, and – as driven – featured nearly the full gamut of Audi’s high tech systems developed for to outdo the competition in a technologically ever-escalating large luxury car segment.

 

Showcasing the future

 

Driven briefly during the A8’s initial launch and before this top-of-the-line model was even fully certified for production, the tested W12 represents the pinnacle of the A8’s sophistication, with many of the model line’s more advanced systems. The world’s first level three autonomous production car – on a scale of five – when its systems are fully unlocked depending on legislation in various markets, the A8’s innovative features centre around its Audi AI [artificial intelligence] processing system and standard 48-volt mild hybrid technology, the latter of which recovers power through regenerative braking and powers numerous electrical systems.

Almost exclusively powering electrical and more advanced assistance and safety systems without interfering with or corrupting the A8’s driveline operation, Audi’s 48v starter/generator system can, however, pitch in directly with a slight torque bump, depending on model and application. That said, the 48v system relieves the combustion engine of much ancillary system load and helps achieve a 0.7l/100km fuel consumption reduction. It also allows for brief coasting at speeds between 55-160km/h, and for stop/start system operation starting from 22km/h on deceleration, The 48v system also powers an optional fully independent active electromechanical suspension system.

 

Effortlessly effective

 

Effortlessly versatile and abundant, the flagship Audi’s magnificent twin-turbo 6-litre W12-cylinder engine is essentially a slightly de-tuned version of the same engine used by most range-topping Bentleys. Highly refined and progressive, the A8’s W12 produces a mighty 577BHP at around 6,000rpm and a massive 590lb/ft torque plateau throughout a broad and accessible 1,300-5,000rpm band. Responsive from standstill with its lightly boosted turbochargers and short gasflow paths, the A8 is expected to swiftly haul its estimated over 2.2-tonne mass through 0-100km/h in 4-seconds or little over, and onto an easily achievable electronically limited 250km/h top speed.

Moving swiftly and confidently with abundant mid-range flexibility and effortless across the board delivery, the W12 also benefits from a smooth and slick 8-speed automatic gearbox that optimises output for performance, efficiency and refinement. Putting power to tarmac through Audi’s Quattro four-wheel-drive system, the A8 develops high levels of road-holding and traction Driving with a 60 per cent rear bias for better agility, the A8 can apportion power back and forth for best grip in a prevailing situation, while optional four-wheel-steering makes it more agile despite its big heavy engine being positioned just ahead of the front axle.

 

Control and composure

 

Turning the rear wheels in the same direction as the front at higher speeds for better agility, road-holding and stability, and in the opposite direction for tighter cornering lines and manoeuvrability, four-wheel-steering effectively makes the long wheelbase A8 drive like a smaller car, and sublimely well manages the W12’s nose-heavy weighting, as demonstrated through a tight slaloms during test drive. Easy to manoeuvre and park with its 11.8-metre turning circle, cameras and vast array of driver-assistance and collision prevention sensors, warnings and semi-autonomous AI systems – where permitted – the A8 can also be fitted with optional remotely operated auto-parking.

Built using lightweight aluminium intensive construction and 24 per cent stiffer than its predecessor for improved handling, comfort and collision safety, the A8’s most impressive feature is, however, its active electromechanical suspension. Powered by its 48v system and controlled by its zFAS AI brain and high speed processing system, this leverages numerous sensors, radars and cameras to independently adjust each wheel’s vertical movement through individual electric motors. In concert with four-wheel-steering, active electromechanical suspension is a game-changer that makes the A8 handle with the agility of a smaller, lighter car, yet also improves ride comfort and stability.

 

Stately sophistication

 

Reading and responding to road texture, cornering forces and other parameters with intuitive fluency, the A8’s active electromechanical suspension delivers eagerly nimble, taut and sure-footed, cornering characteristics, and supple, forgiving ride composure. Hugely impressive, it also features predictive functions that further leverage the AI system, and allow the A8 to raise or lower individual wheels in time to keep the car level and smooth as it virtually glides over even significant bumps, cracks and imperfections. Fully active, the electromechanical suspension serves as a safety system that swiftly raises the A8’s body and point of impact when collision is anticipated.

A stately luxury car with sculpted surfacing, attention to detail and an elegantly assertive demeanour, the A8’s design centres around its huge hexagonal grille. Luxurious, spacious and comfortable inside, the A8’s cabin is refined, quiet and brimming with high quality leathers, suede, metals and woods. Extensively equipped with comfort, convenience and safety systems too long to list, the A8 notably features a haptic button, advanced voice recognition dual screen infotainment system. Meanwhile, Audi AI’s self-driving features, when enabled depending on legislation, would be able to stop, start, steer and brake up to 60km/h in the right circumstances.

LOS ANGELES — A sheet of paper bearing Paul McCartney's handwritten lyrics to "Hey Jude" sold for $910,000 in an online auction held Friday to mark the 50th anniversary of the Beatles' historic split.

The document penned by McCartney and used during the 1968 London recording of the classic song at Trident Studios was sold for more than five times its pre-sale estimate.

California-based Julien's Auctions shifted its sale of some 250 Beatles memorabilia online due to the coronavirus pandemic, with fans around the world bidding for guitars, rare vinyl and autographed items.

Friday marks exactly half a century since an interview given by McCartney sealed the acrimonious end of the "Fab Four," widely considered one of the most influential bands in history.

Asked if he foresaw a time when his prolific songwriting partnership with fellow Beatle John Lennon would restart, his blunt reply — "no" — spoke for itself.

McCartney wrote "Hey Jude" after an earlier split — Lennon's divorce from first wife Cynthia following his affair with Japanese artist Yoko Ono.

The song was composed to comfort Lennon's son Julian during his parents' break-up, and was initially titled "Hey Jules."

The handwritten document sold Friday contains partial lyrics along with annotations including the word "break" used to aid the song's recording.

Other items included a drumhead with the Beatles' logo used during their first US tour gig in 1964, sold for $200,000, and a handwritten shooting script page for the "Hello, Goodbye" music video in 1967, fetching $83,200.

A brass ashtray used by Ringo Starr at the Abbey Road recordings in the 1960s earned $32,500.

 

Utopia or nightmare?

The Circle

Dave Eggers

New York: Vintage Books, 2014

Pp. 497

 

“The Circle” is a novel bordering on science fiction of the type that could conceivably become true.

Mae is a very bright young woman from a small nondescript California town. After graduating from college, she had worked at the local utilities company for over a year, enduring boredom and non-recognition of her considerable computer skills but stayed on because she needed to pay off her student loans. “All of it felt like something from another time, a rightfully forgotten time, and made Mae feel that she was not only wasting her life but that this entire company was wasting life, wasting human potential and holding back the turning of the globe”. (p. 11)

Everything changes when Annie, Mae’s former college roommate, helps her land a job at the Circle, the world’s leading tech company that has subsumed most of the others. Annie is part of the Gang of 40, the leading innovators and thinkers at the company, headed by three executives referred to as the Three Wise Men. The Circle seems modelled on the actual Google campus in Mountain View, California, but exponentially magnified. It’s a total environment with extensive eating, cultural, sports, fitness, social and medical facilities, in addition to offices, laboratories, exhibition halls and dormitories. The company takes good care of its employees; Mae is even able to get comprehensive health insurance for her parents, especially meaningful as her father suffers from a debilitating degenerative disease and is struggling with poor insurance coverage. A thousand threads link the employees to the company.

Mae begins in Customer Experience (once called customer service) and excels in her work, but she finds out that this is not enough. Employees are expected to attend the many events on campus and to keep in constant touch with their colleagues, friends and customers via social messaging. Soon she has multiple screens on her desk, each devoted to a particular type of communication. Going off on one’s own or doing something spontaneously off campus without communicating are viewed with suspicion; everyone should document, share and benefit from everything.

Oddly, one of the Wise Men, the boy genius who envisioned the idea of the Circle and devised the technology that made it possible, is seldom seen around the campus anymore. But his invention is pervasive: The Unifying Operating System combines users’ social media profiles, payment systems, passwords, email accounts, preferences, tools, etc. “You had to use your real name, and this was tied to your credit cards, your bank… One button for the rest of your life online… Though some sites were resistant at first, and free-internet advocates shouted about the right to be anonymous online, the TruYou wave was tidal and crushed all meaningful opposition… the actual buying habits of actual people were now eminently mappable and measurable, and the marketing to those actual people could be done with surgical precision”. (pp. 21-22)

Most users are delighted as it simplifies their lives, but there are a few detractors. According to Mae’s ex-boyfriend, who wants to live a different kind of life, “the tools you guys create actually manufacture unnaturally extreme social needs”. (p. 134)

Having created a strong commercial base, the Circle expands into other fields with multiple projects aimed at eliminating all society’s ills and documenting everything, such as how many trees in the Amazon rainforest, to arrive at total knowledge. All this data is stored on the cloud and non-deletable. With the aim of ending child abductions, chips can be implanted in all children to track their location. With the aim of ending corruption and deepening democracy, politicians are encouraged to wear a device to make all their actions transparent. Those who don’t wear the device are assumed to be doing something wrong. Soon everyone could wear it, their every action being broadcast on public screens. The Circle is closing: Everyone is transparent, and everything can be known. The Circle is poised to take over governmental functions. Mind-reading and mind-control are only a click away.

Eggers’s implicit subtext is that the Circle is a very “white”, elite enterprise where social mobility depends on unquestioningly adopting certain values and practices. Under a veneer of choice, there is subtle, but effective coercion. Employees can vote on many things, such as if they want more vegetarian options at lunch, but larger priorities are already set in stone. What will happen to the outliers, the poor and the socially disadvantaged who have no access to this system? In effect, two parallel worlds are emerging: Mae “found it difficult to be off-campus… There were homeless people, and there were the attendant and assaulting smells, and there were machines that didn’t work, and floors and seats that had not been cleaned, and there was, everywhere, the chaos of an orderless world”. (p. 373)

With the fast-paced, riveting story of Mae’s induction into the Circle, Eggers shows the dangers of runaway technology even if guided by geniuses with utopian ideas. There is also an implicit critique of neoliberalism which eats away at government responsibility for its citizens. The story poses urgent questions: Should being “connected” be mandatory all the time? Are thousands of virtual friends better than solid, face-to-face friendships? Does society need to know everything? Should privacy be obliterated? Can the world be perfect?

Coronavirus found in air samples up to 4 metres away from patients

By - Apr 12,2020 - Last updated at Apr 12,2020

WASHINGTON — A new study examining air samples from hospital wards with COVID-19 patients has found the virus can travel up to four metres — twice the distance current guidelines say people should leave between themselves in public.

The preliminary results of the investigation by Chinese researchers were published Friday in Emerging Infectious Diseases, a journal of the US Centres for Disease Control and Prevention (CDC).

They add to a growing debate on how the disease is transmitted, with the scientists themselves cautioning that the small quantities of virus they found at this distance are not necessarily infectious.

The researchers, led by a team at the Academy of Military Medical Sciences in Beijing, tested surface and air samples from an intensive care unit and a general COVID-19 ward at Huoshenshan Hospital in Wuhan. They housed a total of 24 patients between February 19 and March 2.

They found that the virus was most heavily concentrated on the floors of the wards, "perhaps because of gravity and air flow causing most virus droplets to float to the ground."

High levels were also found on frequently touched surfaces like computer mice, trashcans, bed rails and door knobs.

"Furthermore, half of the samples from the soles of the ICU medical staff shoes tested positive," the team wrote. "Therefore, the soles of medical staff shoes might function as carriers."

 

Airborne threat?

 

The team also looked at so-called aerosol transmission — when the droplets of the virus are so fine they become suspended and remain airborne for several hours, unlike cough or sneeze droplets that fall to the ground within seconds.

They found that virus-laden aerosols were mainly concentrated near and downstream from patients at up to 4 metres — though smaller quantities were found upstream, up to 2.4 metres away.

Encouragingly, no members of the hospital staff were infected, "indicating that appropriate precautions could effectively prevent infection," the authors wrote.

They also offered advice that bucks orthodox guidelines: "Our findings suggest that home isolation of persons with suspected COVID-19 might not be a good control strategy" given the levels of environmental contamination.

Aerosolisation of the coronavirus is a contentious area for scientists who study it, because it is not clear how infectious the disease is in the tiny quantities found in ultrafine mist.

The World Health Organisation has so far downplayed the risk.

US health authorities have adopted a more cautious line and urged people to cover their faces when out in public in case the virus can be transmitted through normal breathing and speaking.

'Friends' reunion delayed by coronavirus

LOS ANGELES — The much-anticipated "Friends" reunion has been delayed and will not be available at the launch of HBO Max, the new streaming platform said Friday, as the global coronavirus pandemic shuts down productions across Hollywood.

News of the unscripted special had delighted fans of the beloved US sitcom, which remains wildly popular even among viewers too young to remember its original run, which ended in 2004.

Stars Jennifer Aniston, Courteney Cox, Lisa Kudrow, Matt LeBlanc, Matthew Perry and David Schwimmer have signed up to return to the comedy's original soundstage on the Warner Bros. Studio lot outside Los Angeles.

But a spokesman told AFP Friday the special will not be available for HBO Max's May launch as planned, adding that it will be coming to the streaming platform "soon." 

Production has not yet taken place due to the coronavirus lockdown, part of measures put in place for billions around the globe to break transmission of the virus which has killed more than 100,000 people worldwide.

A remote or virtual reunion was not considered due to the significance of the original soundstage, according to Variety.

Each actor is expected to receive $2.5 million for taking part in the special, it reported.

WarnerMedia's Sean Kisker this week confirmed the May launch of HBO Max itself, which will cost $14.99 a month, remains "still very much on" schedule.

The "Friends" back catalogue is a key selling point for the new streaming platform as it enters a fiercely competitive marketplace alongside Netflix, Disney+, Amazon Prime and Apple TV+.

Unveiling the special in February, Kevin Reilly, chief content officer at HBO Max, said the show about a close-knit group of friends living in New York City had captivated "viewers generation after generation." 

"It taps into an era when friends — and audiences — gathered together in real time and we think this reunion special will capture that spirit, uniting original and new fans," he said.

Aniston's Instagram post in February teasing the special drew nearly 4.8 million likes in three hours.

"Friends" was among the most-watched shows on Netflix until all 10 seasons of the show were reclaimed last year by WarnerMedia, which owns HBO Max.

Seen on US television from 1994 to 2004, it won dozens of awards and garnered global celebrity for Aniston and her co-stars.

 

Last century's epidemics far more deadly than 21st century's

PARIS — Before the emergence late last year of the novel coronavirus, which has now killed more than 100,000 people, the 21st century's epidemics had been far less deadly than the pandemics of the previous century.

Here are the major epidemics of the last two centuries, starting with the most recent:

 

Ebola: 2013-2016 and 2018-to date

 

The deadliest epidemic of the haemorrhagic fever Ebola broke out in West Africa in December 2013 and lasted more than two years, killing more than 11,300 people, mainly in Guinea, Liberia and Sierra Leone.

First identified in 1976, Ebola is less contagious than other viral diseases, but is particularly lethal, killing around 50 per cent of cases.

The virus re-emerged in August 2018 in the eastern Democratic Republic of Congo where it has so far killed more than 2,200. On April 10, 2020 a new case was reported, just three days before a deadline that would have marked the official end to the epidemic.

 

Swine flu: 2009-2010

 

The World Health Organisation (WHO) says 18,500 people died of "Swine flu", or H1N1, which was first uncovered in Mexico and the United States in March 2009.

The Lancet medical review, however, puts the toll at between 151,700 and 575,400.

The pandemic alert was launched on June 11, 2009 and lifted on August 10, 2010 but the virus turned out to be not as deadly as first feared.

Vaccines were rushed out, but in hindsight, the West, particularly Europe, and the WHO were criticised for overreacting at a time when annual influenza epidemics every year kill between 250,000 and 500,000 people, according to the Geneva-based UN health agency.

 

Bird flu: 2003-2004

 

The deadly H5N1 strain of bird flu killed more than 400 people, mainly in Southeast Asia, after appearing in 2003. It first ravaged poultry farms in Hong Kong, before being transmitted to humans. The WHO declared a global health emergency, but the toll remained limited.

 

SARS: 2002-2003

 

Severe Acute Respiratory Syndrome first emerged in southern China in November 2002 before sparking a health crisis in mid-2003, in particular traumatising Asia.

It killed 774 people, four fifths of whom were in China and Hong Kong. It was transmitted to humans from horseshoe bats, eventually spreading to around 30 countries. It had a mortality rate of 9.5 per cent.

 

AIDS: 1981-to date

 

AIDS is by far the most deadly epidemic of modern times: according to UNAIDS some 32 million people around the world have died of the disease which affects the immune system and leaves people vulnerable to opportunistic infections.

Today around 24.5 million people have access to retroviral drugs which, when taken regularly, efficiently stop the illness in its tracks and heavily reduce the risk of contamination.

 

Hong Kong flu: 1968-1970

 

Around one million people died of the Hong Kong flu, according to the US Centers for Disease Control and Prevention (CDC).

Transmitted around the world between mid-1968 and early 1970, it in particular killed many children. It first started in Hong Kong, spread through Asia and reached the United States in late 1968. After lying low for several months it then hit Europe in late 1969.

 

Asian flu: 1957-1958

 

Around 1.1 million people died of Asian flu, according to the CDC.

The pandemic hit in two aggressive waves. The virus first appeared in southern China in February 1957. Several months went by before it reached America and Europe.

The disease, which results in serious lung complications, in particular affected the elderly.

 

1918-1919: Spanish flu

 

Spanish flu hit a large part of the world's population in the wake of World War I, killing up to 50 million people, according to the CDC.

Striking between September 1918 and April 1919, it is considered the most deadly in history over such a short period.

Five times more people died of it than did in World War I. The first victims were recorded in the United States, before it spread to Europe and then around the world.

Its mortality rate was estimated at more than 2.5 per cent, according to the CDC.

Robots may become heroes in war on coronavirus

By - Apr 09,2020 - Last updated at Apr 09,2020

SAN FRANCISCO — Long maligned as job-stealers and aspiring overlords, robots are being increasingly relied on as fast, efficient, contagion-proof champions in the war against the deadly coronavirus.

One team of robots temporarily cared for patients in a makeshift hospital in Wuhan, the Chinese city where the COVID-19 outbreak began.

Meals were served, temperatures taken and communications handled by machines, one of them named "Cloud Ginger" by its maker CloudMinds, which has operations in Beijing and California.

"It provided useful information, conversational engagement, entertainment with dancing, and even led patients through stretching exercises," CloudMinds president Karl Zhao said of the humanoid robot.

"The smart field hospital was completely run by robots."

A small medical team remotely controlled the field hospital robots. Patients wore wristbands that gathered blood pressure and other vital data.

The smart clinic only handled patients for a few days, but it foreshadowed a future in which robots tend to patients with contagious diseases while health care workers manage from safe distances.

 

Checkup and check out

 

Patients in hospitals in Thailand, Israel and elsewhere meet with robots for consultations done by doctors via videoconference. Some consultation robots even tend to the classic checkup task of listening to patients' lungs as they breathe.

Alexandra Hospital in Singapore will use a robot called BeamPro to deliver medicine and meals to patients diagnosed with COVID-19 or those suspected to be infected with the virus in its isolation wards.

Doctors and nurses can control the robot by using a computer from outside the room, and can hold conversations with the patient via the screen and camera.

The robot reduces the number of "touch points" with patients who are isolated, thereby reducing risk for healthcare workers, the hospital's health innovation director Alexander Yip told local news channel CNA.

Robotic machines can also be sent to scan for the presence of the virus, such as when the Diamond Princess cruise ship cabins were checked for safety weeks after infected passengers were evacuated, according to the US Centres for Disease Control.

Additionally, hospitals are turning to robots to tirelessly rid room, halls and door handles of viruses and bacteria.

US firm Xenex has seen a surge in demand for its robots that disinfect rooms, according to director of media relations Melinda Hart.

Xenex's LightStrike robots have been used in more than 500 healthcare facilities, with the number of deployed bots rising due to the pandemic, Hart said.

"We are getting requests from around the world," Hart said.

"In addition to hospitals, we're being contacted by urgent care centres, hotels, government agencies and pharmaceutical companies" to disinfect rooms.

Shark Robotics in France began testing a decontamination unit about a month ago and has already started getting orders, according to co-founder Cyril Kabbara.

 

Worth the price?

 

The coronavirus pandemic has caused robotics innovation to accelerate, according to Lesley Rohrbaugh, the director of research for the US Consumer Technology Association.

"We are in a time of need for some of this technology, so it seems like benefits outweigh costs," Rohrbaugh said.

Artificial intelligence, sensors and other capabilities built into robots can push up prices, as can the need to bolster high-speed Internet connections on which machines often rely, according to Rohrbaugh.

Innovations on the horizon include using drones equipped with sensors and cameras to scan crowds for signs of people showing symptoms of coronavirus infection.

A team at the University of South Australia is working on just that, in collaboration with Canadian drone maker Draganfly.

"The use will be to identify the possible presence of the virus by observing humans," said university professor Javaan Singh Chahl.

"It might form part of an early warning system or to establish statistically how many people are afflicted in a population."

His team is working on computer algorithms that can spot sneezing or coughing, say in an airport terminal, and remotely measure people's pulses and temperatures.

Video calls and good cameras

By - Apr 09,2020 - Last updated at Apr 09,2020

When making a video call, do you use a laptop computer or a mobile device like a smartphone or a tablet? Is the quality of the camera you have good enough to optimise the experience and to bring it as close as possible to the real thing?

Over the last month or so video calls have shown how important the technology can be and how useful it is in times where physical contact between people and in-person meetings are prohibited or dramatically reduced.

Video calls and videoconferencing have been fashion for a long time in business. Private use of the technique has been low to moderate till earlier this year. It is only recently that it has been widely used for personal communication, because of the confinement situation.

Personal and business video calls have increased significantly and everything indicates that it is going to be the case for some time. Even when confinement is lifted or reduced, it all looks like we will heavily rely on video calls to communicate between us, for whatever reason, for pleasure, for private purpose or to conduct business.

Interestingly, the voice and video calls over WhatsApp and that were blocked in Jordan by the system until last month are now allowed and at the reach of each and every one. This alone is a sign of the times – a rather positive one in this very case. Indeed, video calls over WhatsApp are really handy for they can be used instantly, do not require you to start another software application like Skype, Messenger or Zoom for example, and – the icing on the cake – they use your quickly available and main contacts list.

Now the camera question.

Understandably having a good camera makes a big difference when it comes to video calls. If you make the call with a tablet or a smartphone that was manufactured after say 2013 or 2014, which probably is the case of the majority, then any model, of any brand, at any price, will more than ensure a good image. This is just how modern mobile devices are, by design.

The game may be a little different when it comes to laptop computers. It is only in very recent and middle to high-end models that manufacturers have taken the trouble of integrating good quality cameras, usually called webcams. The lens would generally be located in the top centre of the screen and would be pointed at you.

I have compared the webcams in two Lenovo laptop models: one Thinkpad made in 2018 and one IdeaPad made in 2016. The difference in manufacturing is only two years, but the difference in image quality is huge, with the Thinkpad providing a high-resolution, sharp image, while the IdeaPad’s was barely acceptable by today’s standards. The comparison is all the more valid that the two models are of the same, well-known brand.

Going for a smartphone or a tablet guarantees good image, but at the expense of a smaller screen, unfortunately. If it is a one-on-one video call, this would probably not be a hindrance, but if it is a group call or a video conference, you definitely need both: the best possible camera and an as-large-as-possible screen.

As for desktop computers, the kind that is almost not used anymore at home, one can always buy and add an external USB webcam to place atop the monitor. In most cases this provides superior quality image: Logitech, Microsoft, Creative Labs and Razer Kiyo make the best models, at prices that vary between JD50 and JD150. Even those who have a new laptop with a relatively good camera sometimes go for such an additional top-quality external webcam to be sure to have the best possible resolution image.

When videoconferencing the most demanding also go for an external USB microphone that completes the visual experience with equally good sound to match the image.

Amid coronavirus, students flock to Kahoot! and Duolingo. Is it the end of language teachers?

Every day, Massachusetts seventh-grader Kaylyn Wilson takes a break from doing homework online and opens an app on her phone for a half-hour foreign language lesson.

“The boy has three green bikes and an egg,” the 12-year-old announced to her family in French at the start of her third week using the mobile app from Rosetta Stone, the language-learning software giant.

Wilson doesn't yet need to study a language for credit. But during the school shutdowns to contain the coronavirus, her father saw Rosetta Stone advertise free accounts for students – an offer other language-learning software companies have made as well. Wilson decided to give it a go.

“I really like learning French, and it doesn’t feel like a chore to me,” she said.

As children nationwide settle into weeks and months of remote learning, educational technology companies are having a heyday, marketing their products as must-have solutions to keep students with Internet access connected and engaged. Few were poised to do so as well as language-learning software companies, which have spent years honing the digitised, personalised, gamified experience of a self-paced education.

Programmes like Rosetta Stone, Duolingo, Babbel, and Kahoot! have been used in schools for years, with a catch: They're usually paired with a teacher. The tools could supplement foreign-language and English language instruction, but a few schools quietly used them to fully replace a certified educator that was too hard to find or too expensive to hire.

CEOs of the companies have long stressed their software isn't meant to supplant educators. But with hundreds of thousands of new users logging in from home, a global test – at least for this corner of online learning – is underway: Just how well can students learn on their own, through software, without a teacher?

And how much will this digitised education experiment change learning once children eventually return to traditional classes?

“I do think that this is one of those watershed moments,” said Matt Hulett, CEO for Rosetta Stone. The company has added 10,000 to 20,000 new users each day since it dropped subscription fees.

Hulett wouldn’t share exactly how that translated to specific earnings, but he said the first quarter of 2020 stood to be a strong one for Rosetta Stone's consumer business, made of school and student accounts and adult subscribers.

'Technology and teachers are intertwined'

“We believe that teachers and technology are intertwined,” Hulett said. “We don’t believe there’s a self-learning trend that’s going to replace teachers.”

But in this unusual time, marketing materials position the products as the home-schooling solution for the coronavirus epidemic.

"In light of the current COVID-19 situation leaving millions of kids across the US doing their school work from home, the global language & literacy company, Rosetta Stone, is stepping up to help provide those work-from-home parents some relief," the company announced in press materials after it dropped subscription fees for students.

Language education experts praised the companies for providing free resources with no strings attached. But they're concerned an increased reliance on software in lieu of real teachers – in virtual or traditional settings – could check the box for proficiency without giving students all the tools to read, write and understand a new language.

“How you can use language in a limited, computer-based environment is one thing," said Howie Berman, head of the American Council on the Teaching of Foreign Languages. "But once you’re out of that environment, can you actually use the language in a real-world setting?”

Academic researchers applauded the companies as well but said their programmes weren't a blanket solution. The software can't always be adapted for students with disabilities or those who have limited access to the Internet.

"It's important to recognise these resources do not take the place of quality teaching and that not all tools are designed for all types of students," said Kara Dawson, a professor of educational technology at the University of Florida.

How well do language-learning apps work?

In the beginning, most language-learning software focused on the consumer market – average adults who wanted to pick up a new language in their free time, on a home computer or in recent years, on mobile apps.

Rosetta Stone, which started in 1992, was still selling boxes of its iconic yellow CDs to consumers into the start of the 2010s. Now, like other companies, it’s shifted to emphasising subscription-based services that feature speech-recognition. On Rosetta Stone's latest iPhone app, users can point their phones at an object, which the app will then translate into the language the user is learning. The company also has offered to connect paying subscribers with free, live tutors for virtual sessions through the end of June.

For the language-learning companies, selling classroom software is relatively new.

The concept is generally the same across companies: Individual students walk through the exercises to practice grammar and pronunciation, and the software offer teachers feedback about how each student is doing.

Rosetta Stone also offers English literacy services to schools. In 2012, it purchased Lexia Learning, which supplements elementary English instruction and also helps students learning English as a second language.

Before the pandemic, Rosetta Stone was serving 17,000 schools and 4 million students with English literacy and foreign-language services, said Maya Goodall, a company director. That number is now much higher.

Babbel, based in Berlin, Germany, also has offered free access to students during the pandemic and has added more than 50,000 new young users, including around 10,000 new students in the US, a spokesperson said.

There's scant research on the effectiveness of the latest language-learning software – in part because the technology is moving so fast. But for math and reading, a recent review of high-quality studies suggested computer-assisted learning programmes that help students practice specific skills led to big academic gains.

The most effective programmes had key features: They were interactive, allowed students to progress at their own speed and adapted to their abilities, said Phillip Oreopoulos, an economics professor at the University of Toronto and one of the authors of that review. The best programmes also fed data back to teachers about student performance, he added.

Even Oreopoulos downloaded Duolingo for his children, ages 11 and 9, when their Toronto schools shut down three weeks ago.

"They don’t seem to mind spending half an hour a day conjugating verbs in French, so I’m happy about that,” he said. “I don’t know if it’s helping in the long run, but it’s worth trying and keeps them busy.”

Game-based education apps surging

Duolingo entered the language-learning market in 2012 with a game-based online platform and mobile app. And another key feature: It’s free.

In 2015, the company rolled out Duolingo for Schools, which allowed teachers to track the progress of entire classes. It's also free and supported through advertisements.

As of March 19, shortly after the pandemic caused the closure of nearly all schools in America, Duolingo for Schools signups were increasing 425 per cent week-over-week, driven largely by teachers assigning remote work and parents looking for resources to home-school their children, said spokeswoman Michaela Kron.

Carlos-Luis Brown, a Spanish teacher at Wilmington High School in Massachusetts, said he's used Duolingo for at least four years to supplement instruction – it's part of his students' graded homework.

During the shutdowns, he said, Duolingo has become "the most consistent part" of what his students are doing at home.

Kahoot!, another game-based service for world languages and other academic subjects, also offered free premium accounts to teachers and schools through the end of this academic year. During the height of new traffic, the company was getting more than 100,000 new accounts per day, a spokeswoman said.

Few states require foreign language

The sudden spike in language-learning software users comes at a paradoxical time: Few states require students to study a world language.

Just seven states, including New York and Michigan, specifically require one or two years of a foreign language to graduate, according to the latest data compiled by the nonpartisan Education Commission of the States. Twenty-two other states allow for local districts to declare multiple options for students to satisfy the foreign-language requirement, such as by taking computer coding or another humanities credit.

Almost all states reported shortages of foreign language teachers in middle and high school in the 2016-17 school year, according to a federal report.

In 2016, one rural high school in Maine struggling to secure a foreign language teacher instead used the funds to buy a Rosetta Stone class package.

Brown said he used to work for a charter school that wanted to use Rosetta Stone as the curriculum for all its elementary grades. Brown resisted the proposal – he feared it would remove teachers.

"What we're really teaching is culture, and as a byproduct of that, you learn a language," Brown said. "It's a study of a different life and a different way, and the idea that students are able to tell their own story, and hear other people's stories, is critical."

 

Best of both worlds

 

Some teachers will continue to incorporate what they see as the best of both worlds: robust, face-to-face instruction as well as games and online tools to keep students engaged – even if it's a struggle in the new world of remote learning.

In a normal year, Richard de Meij, a world language teacher at Hartford Public High School in Connecticut, uses a variety of in-class and virtual tools. Students use an app to engage in controlled, monitored conversations with native Spanish speakers in other countries. They must watch the soap opera "Destinos" online and answer questions about the show. They take quizzes on Kahoot! They can practice on Duolingo for extra credit.

“Duolingo is free and excellent for vocabulary building, but not necessarily communicative skills,” de Meij said.

Now that everyone is at home, de Meij, who speaks eight languages, is teaching by video and encouraging students to stay connected to their studies via online software.

“I think face-to-face learning in a classroom will never go away," he said. "But it's a golden moment for these language tools and learning platforms."
