‘Super-spreaders’: COVID19 myth or reality?

PARIS — Can a single COVID-19 patient infect dozens of others? Although transmission rates in the current outbreak appear to be far lower, a variety of factors can lead to an individual infecting many.

The concept of so-called “super-spreaders” — patients who typically infect far more people than the standard transmission rates — emerged in previous outbreaks of diseases such as Sars and Mers.

Amesh Adalja, an expert in emerging infectious diseases at John Hopkins University, said the term was not scientific and there was no set quantity of transmissions that would define a super-spreader. 

“But, in general, it is usually a markedly higher figure when compared to that of other individuals,” he told AFP. 

A range of variables govern how many people an individual infects, from how fast they shed the virus to how many people they come in to close contact with.

The novel coronavirus has a typical transmission rate of 2-3 — that is, every confirmed case appears to infect between two and three other people on average. 

But the pandemic has thrown up at least two patients who appear to have been super-spreaders.

 

Suspected super-spreaders

 

One suspected super-spreader, a British national, appears to have infected a dozen others when he returned from Singapore and then went skiing in the Alps.

He recovered, but may have infected another five people after returning home.

In South Korea, which has the second highest number of COVID-19 cases outside of Italy, a woman known as Patient 31 appears to have infected dozens of others.

But in an ever better-connected world, it can be challenging to definitively link transmissions to an individual patient.

“It’s possible that what we call super-spreaders exist, those patients who don’t only infect 2-3 others but could infect dozens,” said Eric Caumes, head of infectious and tropical diseases at Paris’ Pitie-Salpetriere Hospital. 

“The problem is we aren’t spotting them.”

According to Olivier Bouchaud, head of infectious diseases at that Avicenne hospital in Paris’ suburbs, variable transmission rates could be down to how fast a patient sheds the virus once infected.

“That’s just a hypothesis at this point,” he said. “Obviously we don’t have a clear explanation, and there’s nothing specific to COVID-19.”

Another unknown is the role played by young children, who are less severely affected by the virus but are capable of transmitting it — part of the reason many countries have moved to close schools in recent days.

 

‘Highly variable’

 

Cristl Donnelly, professor of Applied Statistics at the University of Oxford, said all disease transmission was by nature “highly variable”.

“But we are not all the same, we vary in our immune systems, in our behaviour, and in where we happen to be,” she said. 

“All of these things can affect how many people we would transmit to.”

Bharat Pankhania, an infectious diseases expert at Britain’s Exeter University, even disputed whether super-spreaders existed.

He said that the biggest factors determining transmission were environmental, made worse in dense-populated cities.

“These circumstances often are: crowding; a confined space with poor ventilation; poor infection control, meaning lots of non-porous, hard surfaces which can keep a virus viable for a longer time; a favourable ambient humidity; and the infected person usually being in the early phase of their illness, when virus secretions are at their peak,” he said.

It’s due to these contributing factors that many experts are reluctant to talk in terms of super-spreaders. 

Added to this, as France’s health minister has pointed out, the term might be used to stigmatise individuals, when it is likely they transmitted COVID19 without realising.

Twitter tests its own version of disappearing stories

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

SAN FRANCISCO — Twitter Inc. is testing a way for users to post photos and videos that disappear after 24 hours — similar to stories products offered on rival social networks — in a push to encourage people to share more often on its service.

The San Francisco-based company calls these disappearing posts Fleets — short for fleeting tweets — and wants the tool to ease the pressure of online sharing. Similar to tweets, Fleets are text-first but videos, GIFs and photos can be added.

“Some of you tell us that you’re uncomfortable to Tweet because Tweets are public, feel permanent, and have public counts,” Twitter wrote in a blog post last week. “We hope that people who don’t usually feel comfortable Tweeting use Fleets to share musings about what’s on their mind.” The test is only available in Brazil.

Chief Executive Officer Jack Dorsey is under threat from activist investment firm Elliott Management Group, which wants to push him out of the top job. Dorsey has two jobs — he also runs payments company Square Inc. — and Elliott thinks Twitter needs a full-time CEO.

Twitter has also developed a reputation for moving slowly when it comes to launching new products and features. It’s common for some ideas to percolate internally for years before they ever appear to Twitter users, a much slower cadence than other social media companies. Even expanding the length of tweets from 140 to 280 characters took years of debate and discussion inside the company.

The Fleets test provides at least the perception that Twitter is moving forward. Disappearing posts have become a popular way to share on competing social sites, including Facebook Inc.’s Instagram and Snap Inc.’s Snapchat. More than 500 million people use Instagram’s version of Stories, and Facebook executives have pointed to this as an important growth opportunity for the company’s advertising business. Instagram’s Stories feature already makes up about 10 per cent of all ad spending on Facebook properties.

It’s too soon to say whether Fleets will provide a similar opportunity for Twitter. The company has started testing features in public in recent years, often asking for user feedback before rolling something out more broadly. It’s one of the ways Twitter tries to be more thoughtful about what it launches, but also slows down the process. Instagram, by comparison, unveiled its version of Stories to all global users at the same time in 2016.

An eerie Facebook experience

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

Last week I went through a rather eerie experience with my Facebook (FB) account. I received a request for friendship from someone who passed away about a year ago.

There is a good explanation for this strange FB post that left me breathless for a few seconds. There are also a few questions to ask along the way.

First the explanation. It is actually a simple one. A little more than a year ago I decided to take a kind of sabbatical from FB. I had reached a point where it was just too much for me. I had the feeling that it was unreasonably wasting my time. So I published a post to the attention of all my good friends there, telling them that whereas I was neither cancelling nor closing my FB account, I wouldn’t be visiting the network page anymore, or at least very rarely, if ever.

Fast forward a year or so. Just a few days ago, and after this long absence, I decided to log in FB again and see what was going on there. This is when I saw the “Friend Request” by my late acquaintance. He must have posted it just a little before I decided to take a sabbatical leave, and of course, some time before he passed away.

Now the questions. There is definitely an antisocial side to these so-called social networks. When someone dies in real life, reporting the death to the civil status authorities is not a choice. It is a must and it follows clear regulations, like the short deadline allowed for example. The family must comply by the rules.

When this happens in the virtual life we live on FB there is a huge gap, a major shortcoming in the matter. Significant time can pass before someone cares to obtain a death certificate or any other proof of it and decides to send to FB so that an update can take place. Hence the strange situations like the one I experienced. If no relative or friend acts and sends FB a proof of the death of the departed person the network will do nothing, the account will still be there, displaying all the information, photos and posts that the creator and owner of the account published before passing away.

This is an idiosyncratic trait that is more or less common to all social networks, but the symptoms are particularly obvious and unpleasant on FB, because of the way the network preserves information “forever”. LinkedIn, Twitter, Instagram and others, also tend to hold on to the information though not as firmly as FB.

If social networks want to imitate real life, then they should do it well, to the end, not just partially or erratically. In countless real life situations the owner of an account must show either activity or a proof of life at regular intervals, otherwise the account is automatically terminated. This is true, for example, if you hold a bank account, receive a pension, etc.

We all maintain a certain number of digital online accounts, from simple email (Gmail, Hotmail, etc,) to audiovisual streaming services like Amazon, Netflix or Spotify. With these accounts, however, no mishap similar to the one I described above would happen because these are not social accounts that have been created for everyone to see and share like FB or Instagram.

There is a lot of fine-tuning and improvement that is still necessary to do before we trust social networks more than we do today. Through the years the creators of FB themselves have acknowledged some aspects of the issues and have taken corrective measures even if only partly – like ensuring better privacy for instance. At this point in time, however, nothing has been done about how the network would update the status of a deceased account holder without delay.

How to protect yourself at the gym, one of the germiest places around

By - Mar 11,2020 - Last updated at Mar 11,2020

PHILADELPHIA — Free weights have 362 times more bacteria than a toilet seat, according to a study performed by EmLab P&K, a finding that could bring sweat to your brow before you even launch into your first bicep curl — especially with the new coronavirus in mind.

In the wake of COVID-19, fitness centres are sending e-mails to members about prevention measures. Most include encouragement to stay home if you’re feeling sick. There’s also plenty of phrasing about amping up established disinfecting efforts.

“We’ve been instructing staff to wipe down basically anything that humans will touch — seats you sit on while waiting for class, extra wiping down of door knobs, mic sets for the instructors, etcetera,” says Mariah Ostia, Flywheel Centre City’s studio manager.

Members are being asked to do their part, too.

“Avoid kissing, hugging, and the sharing of cups and water bottles,” reads a Barry’s Bootcamp email.

Add high-fiving to that list, says John Zurlo, Jefferson Health’s division director of infectious disease. (His recommendation: celebratory elbow bumps instead.)

Wondering what else you can be doing to dodge germs at the gym? Zurlo shares some advice to practice on your next visit. Topping the list: keep your hands away from your face.

“If you touch a surface where someone has sneezed, like a gym bench, and then rub your eye with your pinky finger, the virus could spread,” says Zurlo. “Our nose, mouth, and eyes have mucus membranes, and this is where respiratory infections like the coronavirus and the flu enter into the body.”

Cue towels. Carry two with you — one to spread across each machine and one to wipe sweat from your face. Just remember to remain conscious of what surfaces the fabric touches and which sections are still clean. If needed, toss your towel mid-workout in exchange for a new one.

Tissues work as barriers, too, and are especially useful in situations where a towel might feel clunky. Need to adjust sweaty glasses or scratch an itchy nose? Those are prime jobs for a Kleenex.

Likewise, grab a tissue or paper towel to avoid hand contact with water fountain handles. And when you go in for a drink, do so with care.

“It seems like common sense, but try not to touch your cheek to any part of the metal on the water fountain,” says Zurlo. “You could also let the water run for a few seconds.”

Since running to the bathroom sink in between every gym machine isn’t realistic, Zurlo suggests using water breaks as reminders to get those hands clean.

“Probably more so than the soap, rinsing for the full 20 seconds is crucial,” says Zurlo of hand-washing.

Twenty seconds: it’s roughly the amount of time it takes to sing Happy Birthday twice. Or, as noted in a list by the Los Angeles Times, the chorus of Lizzo’s Truth Hurts, Toto’s Africa, or Prince’s Raspberry Beret — all prime additions for your gym playlist.

Hand sanitiser is also handy, and with the coronavirus of concern, Zurlo says you needn’t be too concerned about how often you’re using it.

“In medicine, every time we walk into a patient room, we use hand sanitiser, and when we walk out of the room we use it again — so for physicians, sometimes that means 40, 50, 60 times a day,” says Zurlo. “In my personal life, I’m not using it all the time, but I don’t know if I’d set any limit at the gym.”

Use enough to cover every part of your hands, including rings. And as with the hand sanitiser, utilise sanitising wipes regularly, too.

“It’s good gym etiquette to wipe down machines after you use them,” notes Zurlo. “It’s a big step to also be wiping down every machine before use, but at this point I can’t see a downside to it.”

Ultimately, how to navigate the gym comes down to awareness. To prevent injury, you have to pay attention to form. To prevent sickness, you have to pay attention to what you touch.

Being aware of those around you is important, too, says Zurlo. If someone’s coughing, move.

But as long as you remain mindful, Zurlo says, there’s no need to fear going to the gym, at least for now.

“Maybe I’d feel differently if we start to get hundreds or thousands of [coronavirus] cases in Philadelphia, but I’m certainly not avoiding my local fitness centre,” says Zurlo, who, at the time of the interview, was heading there soon. “I’m just being more cognisant of people around me and of my hands — washing them and 100 per cent keeping them away from my face.”

Samsung Galaxy S20 Ultra: Huge screen, high resolution cameras and (finally) 5G

By - Mar 10,2020 - Last updated at Mar 10,2020

Samsung’s new Galaxy S20 phones have been introduced, and the three models are all a very nice step up from last year’s Galaxy S10s. They all come ready for 5G networks.

I visited Samsung’s headquarters in Plano last week and got some hands-on time with the Galaxy S20, S20 Plus and Galaxy Ultra.

I’ve been testing a Galaxy S20 Ultra for the last week.

Although I’ll mention all the models, this review will concentrate on the Ultra.

 

Cameras

 

If there is one thing I’ve learned over the years, it’s that people will take more pictures if they carry a camera around with them.

I’m a former newspaper photographer, and I used to keep a small point-and-shoot camera in my computer bag because you never know when you’ll want to snap a photo.

Now we all have smartphones and everyone carries a camera all the time.

Facebook, Instagram and Snapchat probably wouldn’t exist without smartphone cameras.

The S20 Ultra has upped the flagship phone camera wars with a three-lens system that features a 108-megapixel mode on the main camera sensor and a 40-megapixel front-facing camera.

The Ultra has three lenses: Telephoto, wide-angle and ultrawide.

The telephoto lens can zoom to 10x (optical) and it can use artificial intelligence to digitally zoom up to 100x — something Samsung calls Space Zoom.

To get the super-high-resolution 108 megapixel mode, you have to select it from the aspect ratio setting on the main camera screen. Note that you can only shoot with the wide-angle lens for 108 megapixel photos (not ultrawide or telephoto).

Why do we need 108 megapixels? We don’t, really, but it allows you to get more detail when you crop into the image.

You really need a tripod or some other support when zooming in more than 10x. Trying to use the 100x zoom setting without camera support is disappointing but not unexpected. It also helps those super zoom shots if the subject is still.

All three S20 models can shoot 8K video at 24 frames per second. Each frame of that 8K video is a 33MP still image, which means you can shoot 8K video and pick out your favourite frames and save them as really high-resolution photos.

 

5G-enabled

 

My Galaxy S20 Ultra came with a Verizon SIM installed, and I was able to use the Verizon 5G towers in neighborhoods in and north of downtown Dallas.

The 5G variant in use by Verizon in Dallas is called Ultra Wideband 5G.

The signal must not travel very far from the towers, but the phone’s display lets you know what type of network you are using.

The 5G networks being installed in this country come in two variants — above 6Hz (called mmWave) and below 6Hz (called Sub6).

The S20 5G and S20+ 5G use Sub6. The S20 Ultra uses Sub6 but also includes the faster millimetre Wave.

I did a speed test on UWB5G and found download speeds of 975 megabits per second, which is just under gigabit (1,000Mbps). This is the kind of speeds we were all promised from 5G, and I’m quite pleased with the results.

Now that Samsung has fired the first shot by including 5G in all three models of the S20, I expect Apple to follow suit with its next iPhone release.

 

Specs

 

The spec list of the S20 Ultra is long and very nice.

It has a 6.9-inch QuadHD+ display with a resolution of 3,200 x 1,440 pixels for a pixel density of 511 pixels per inch.

The screen has a fantastic 120Hz refresh rate, which means the screen refreshes twice as fast as most smartphones for very fluid scrolling and graphics response. Note that the 120Hz refresh rate is not available at the screen’s highest resolution.

The S20 Ultra has a 5,000 milliamp-hour battery, which is as big as I’ve encountered on a phone. I didn’t come close to running it down at the end of the day. The phone has Fast Wireless 2.0 charging, Super Fast wired charging and Wireless PowerShare, which lets the S20 Ultra wirelessly charge other phones.

The Ultra runs Android 10 and comes with 128 or 512 gigabytes of internal storage. It has a microSD card slot to increase the storage capacity to up to 1.5 terabytes.

It runs a Qualcomm Snapdragon 865 processor with 12 gigabytes of RAM (16GB in the model with 512GB storage).

It has 802.11ax Wi-Fi, Bluetooth 5.0 and supports Samsung Pay.

It can be unlocked via face recognition or an in-screen fingerprint reader. Both worked well.

The Ultra can take a 30-minute dunk in up 5 feet of water.

It is also eSim capable, which means you don’t need a physical SIM card if your carrier supports eSIM. This helps you easily switch carriers.

 

Pricing and availability

 

The S20 Ultra comes in Cosmic Black or Cosmic Grey and starts at $1,399. 

The Samsung S20 Ultra is new, but it feels familiar.

It’s the biggest phone I’ve carried around on a daily basis and it still (barely) fits in my back pocket, which is where I keep my phone.

The screen is extremely bright and clear and a joy to use. The buttons are all on the right side, which makes one-handed use easier for someone with big hands like me. If you have small hands, this is not a one-hander. The camera hole in the screen is not very obtrusive at all and I didn’t miss the headphone jack, but I can see where others might.

The star here is the camera. The camera bump on the back side is on the large side, but I didn’t find it hard to use on a flat surface.

Putting it in a case makes the bump a non-issue.

Calls sounded clear and connected quickly. The onboard speakers are above average.

The S20 Ultra is an expensive phone at $1,599.99 for the most expensive model, but it compares with the iPhone 11 Pro Max, which costs $1,449 at its most expensive configuration.

Prices are what the market will bear, and I think the addition of more RAM and a 5G modem more than make up for the price difference.

For power users, especially Android power users, the S20 Ultra is the phone for you.

Pros: 5G, tonnes of RAM, 108MP photos and big zoom.

Cons: Expensive

Bottom line: The S20 Ultra has everything I want in a flagship phone.

Mercedes-Benz GLC200 4Matic Coupe: Fashionable fastback 4x4 refreshed

By - Mar 10,2020 - Last updated at Mar 10,2020

First launched as a 2016 model and now face-lifted for 2020 with some significant drive-train changes and numerous design, cabin and technology updates, the Mercedes-Benz GLC-Class 4Matic Coupe is the more fashion-oriented sister model to the more traditional GLC-Class SUV. Identical in almost every way but its rakish body style and roofline, the GLC-Coupe’s remit is to combine SUV practicality with coupe style. Cross-breeding two trendy automotive features, it could be argued that the four-door coupe SUV doesn’t do justice to either, yet, the GLC-Class coupe does it with more panache than most.

 

Two trends in one

 

A more common sight in recent years as other manufacturers further diversify their model lines and hop on a trendy bandwagon, the four-door coupe SUV isn’t quite the automotive oddity it used to be. In fact, the GLC-Class’s take on this segment seems to be one of the most elegant there is in its interpretation of Mercedes-Benz’ “sensual purity” design language. Restyled for the current year, the revised GLC-Coupe features restyled bumper, light and grille elements, in addition to full-LED technology, new alloy wheel designs and chrome elements running along the sills.

Sitting high off the ground with a broad diamond patterned grill, bulging bodywork and surfacing, high flanks, small glasshouse and low, flowing roofline and lift-back rear, the GLC-Class Coupe has squat stance and dramatic demeanour that emphasises its width. As most modern Mercs, the GLC-Coupe takes very well to the optional AMG Line body kit and staggered top specification 255/45ZR20 front and 285/40ZR20 rear tyres to best realise its assertive aesthetic. Though subtle, the net result of the GLC-Coupe’s visual updates is a classier, sportier and fresher look than before.

 

Subtle electrification

 

Powered by a significantly overhauled engine line-up of turbocharged direct injection 2-litre 4-cylinder petrol engines mated to a 9-speed automatic gearbox and four-wheel-drive, the GLC-Coupe receives a new turbocharger, revised variable valve timing and a new mild hybrid system to meet stringent Euro 6 emissions regulations. The biggest change by far, the 48v mild hybrid system features an integrated starter/generator to recover kinetic energy and help power various systems and features. Developing 13BHP and 110lb/ft torque, the hybrid system can boost the combustion engine for added performance and to enhance efficiency.

Driven in entry-level petrol-powered guise, the GLC200 Coupe’s combustion engine develops 194BHP at 5,500-6,100rpm and 236lb/ft torque. A quick-spooling engine with little turbo lag and big thick and versatile wave of torque over a broad range, the GLC200’s petrol engine output is noticeably augmented by its hybrid system over short bursts, where it feels unexpectedly more responsive at low-end and muscular in mid-range. Off-setting a not insignificant weight gain to 1,820kg owing to its new hybrid and high tech features, the GLC200 is brisk and confident in town, on highway and through country lanes.

 

Firm footing

 

Accelerating through 0-100km/h in 8-seconds and capable of 216km/h, the GLC200 Coupe is at its best riding its generous mid-range torque band and taking advantage of its numerous gear ratios for on-the-move flexibility. Powerful at top-end especially in short bursts, the GLC200 does take a brief moment to wind down on the overrun. Meanwhile, it can return 7l/100km combined cycle fuel efficiency under ideal conditions. Buttoned down and stable at speed as expected, the GLC200 Coupe is a natural long distance driver, while its brakes provide good stopping power and consistency. 

Smooth, composed, refined and comfortable, the GLC200 Coupe’s can however feel firm over sharper bumps and lumps and over choppier road sections. However, the upside is that its huge low profile tyres provide good grip, while its taut suspension well controls body lean through corners for such a high riding and heavy vehicle. Superb on smooth highways, the GLC200 Couple also handles well through corners once one gets accustomed to its proportions. With its direct steering providing quick and tidy turn-in, the GLC200 is committed through corners, with all four driven wheels providing plenty of wet weather traction.

 

Fashion and function

 

Refined and well-insulated inside, the GLC-Class Coupe is spacious in front and provides a well-adjustable, hunkered down and comfortable driving position with good front visibility. However, its fashionably low roofline and small glass are do restrict rear headroom for tall passengers and rear and over-shoulder visibility. However, it is a well-equipped vehicle with a reversing camera and blindspot and lane change warning systems that prove valuable in remedying its visibility issue. In terms of practicality, the GLC-Coupe can wade through 300mm depths, while its spacious boot is easily accessible through its fastback rear hatch.

Sporty yet elegant inside in its aesthetic, the GLC-Coupe is a premium product with plenty of soft textures and an air of quality about it, and features a flowing one-piece centre console, round air vents, thick steering wheel and intuitive controls and infotainment system. Very well-equipped with convenience and safety features from child seat latches to advanced driver assistance systems, the revised GLC-Coupe features an improved and larger infotainments screen, voice command, touchpad and much more, but unfortunately now only features mini-USB ports, which requires an adapter for standard USB devices.

Ageing successfully

By , - Mar 08,2020 - Last updated at Mar 08,2020

Our society is obsessed with age and almost points out all the negatives of ageing. I work with anti-ageing products in my profession, yet I find every age has its beauty and ageing is a mindset. 

 

Live well to age well! 

 

Ageing gracefully is largely a consequence of our earlier health and self-care habits, yet we tend to neglect these until we reach our 40s or 50s. I focus on three areas for successful ageing:

• Outer appearance and what the mirror is telling you

• Health concerns and what your body is telling you

• Mindset transformation and what your mind is telling you 

 

Improving our outer appearance 

 

• Using sunblock

• Using anti-ageing serum and creams

• Always moisturising our skin; it’s our biggest organ so we need to keep it hydrated

• Drinking two to three litres of water daily — studies show that those who stay hydrated daily look younger

• Using hair masks and good treatments to improve brittle hair

• Metabolism tends to slow down with age, often leading to weight gain. So, at least 20 minutes of exercise a day will improve metabolism and improve your mood, too!

• Checking with your doctor if you have a major concern

 

Improving our health

 

• Making your health a top priority. Scheduling regular doctor visits can help identify problems early when your chances for treatment and cure are better

• If you are pre or in menopause, checking with your gynaecologist to help you reduce symptoms

• Maintaining a healthy weight as you age. Studies show that midlife weight gain significantly increases the risk of developing obesity-related diseases 

• Doing strength or resistance training as loss of muscle mass comes with ageing

• Keeping your blood glucose and cholesterol levels under control 

• Doing mental and memory exercises

 

Improving our mindset 

 

• Accepting our age with a positive attitude

• Maintaining meaningful relationships and surrounding ourselves with positive people

• Avoiding negative people as much as possible

• Being proud of our life story that includes loved ones and our adversities and achievements

• Spending quality time with friends and family

• Engaging in activities you enjoy

• Keeping our spirits high

• Having a good time with our children; their enthusiasm is contagious 

I believe that our “health age” (how well we age) matters more than our actual physical age. You can look your best at any age, inside and out!

Why people still love their paper maps

By - Mar 07,2020 - Last updated at Mar 07,2020

Even if everything navigation is pointing in the direction of GPS, you’ll never tear some folks away from their paper maps.

In Northern New Jersey, Stephanie Kivett Ohnegian keeps an atlas in her car because “there are places where the GPS signal doesn’t work” or “the routing is ridiculous”.

Out in Portland, Oregon, Kimberly Davis has paper maps in her earthquake “go bag” – just in case.

And in Newport Beach, California, Christine McCullough has another practical reason for keeping the once-ubiquitous thick, spiral-bound Thomas Guides in her car. As the kids prepare for their driving tests, her edict is “no phones.”

Few folks would dismiss the fact that GPS, for all its imperfections, can be a godsend when we’ve lost our way — assuming it wasn’t GPS that sent us wildly off course in the first place.

Same goes for Apple Maps, Google Maps and Waze.

And those apps are constantly evolving, too.

Apple just delivered a redesigned Apple Maps experience with what the company insists is faster and more accurate navigation, and more comprehensive views of roads, buildings, parks, airports, malls and so on.

Apple unveiled a new Look Around feature that is similar to Google’s Street View, leveraging high-resolution photographs to let you see what major cities look like.

As part of its 15th birthday, Google is rolling out a refreshed look of Google Maps on iOS and Android devices, and adding such new features as the ability for some transit riders to determine whether their bus or train is likely to be on the warmer or colder side.

As digital navigation tools continue to become regular fixtures in getting us to where we’re going, Google Maps is also looking at having an impact on establishing where we are. Google CEO Sundar Pichai blogged that, “one of the next frontiers for Maps will be to help the billions of people who live without a physical address get a digital one”, using latitude and longitude coordinates rather than a street address, which he says would let more folks access things like banking and emergency services, receive personal mail and deliveries, and help others find and patronise their businesses.

San Francisco market researcher Grand View Research estimated the global digital map market to be worth $5.6 billion in 2018. The firm expects the market to continue to expand at a compounded annual growth rate of 12.1 per cent through 2025.

Where does that leave printed maps?

 

Paper maps still sell

 

“Do they still make, even sell, paper maps?” That question from retired New York marketing executive Michael Lissauer is emblematic of our daily reliance on digital navigation. “Other than in a history class, Europe before World War II, who needs a paper map?”

It may surprise Lissauer and others that the answer to the question is yes. They’re actually on the rise. US sales of print maps and road atlases had have had a five-year compound annual growth rate of 10 per cent, according to the NPD BookScan. In 2019, year-over-year sales climbed 7 per cent.

Tony Rodono has certainly heard it all before. He owns and runs The Map Shop. “We’ve had a retail location in Charlotte, North Carolina, for about 30 years, and every day we get somebody walking in saying, ‘How in the world can you stay in business?’”

Not only is The Map Shop still in business but it is also moving to a bigger facility, partly to manufacture three-dimensional “raised relief maps” that are vacuum formed over a mould to help people get a better representation of an area’s topography.

A few of The Map Shop’s older generation customers are sceptical of GPS, he finds. “They have a flip phone that’s tucked away with their map in their glove box for emergencies,” he says. But he’s seeing fewer and fewer customers who fit that description.

Members of AAA can still walk into a local branch and request a TripTik, the spiral-bound notebooks filled with fold-out maps tracking the route to their final destination. An AAA agent would highlight the route with a marker and point out sightseeing spots, restaurants, perhaps places to spend the night. You’d typically walk out with tour books as well.

As a signpost of the digital age, people nowadays can order TripTiks, which first surfaced in 1937, online or through the AAA app and create a digital version.

Dave Arland still frequents aAAA branch before a big car trip. The Indiana public relations executive insists, “Nothing beats the high-resolution printed map! Plus printed maps don’t have an attitude like Siri, Google, or others!”

“I am a paper girl all the way,” says Cindi Gildard, a bookkeeper at Chase Leavitt in Portland, Maine. “I’m not a navigator. I wouldn’t know how to use a GPS if there was one in my vehicle.”

Instead, Gildard relies on the “awesome” “Maine Atlas and Gazetteer”, which she says shows “old little dirt roads and where bridges were washed out”. The Gazetteer uses dotted lines, she adds, to indicate areas in the backcountry where you need four-wheel drive.

 

No signal? No problem. No battery required

 

For her part, Kendra Ensor, the vice president of marketing at Rand McNally in Chicago, says about five years ago the company started to see an uptick in Road Atlas sales. “After all, a printed atlas doesn’t require batteries or a satellite or cell signal,” she says.

Fear of those dead batteries or spotty coverage is a key reason cited by many of the people who responded to USA Today on social media about why they still use paper maps.

“When we were in Nebraska last year with all the flooding, a paper map would have been helpful when both Apple and Google Maps told us to go down a flooded road,” says Barb Gonzalez, a travel photographer and writer based in Bend, Oregon.

There’s a host of other reasons for printed maps, though, from carefully curated collections for historical or scholarly purposes to artistic displays to the accidental stockpile from recent travels.

David Rumsey’s collection of over 150,000 maps is housed at Stanford University. Over 30 years, he amassed atlases, wall maps, globes, school geographies, pocket maps, maritime charts dating from about 1550.

For community planners, real estate agents and engineers, for instance, paper maps are just tools of the trade.

“Suddenly we have these driving directions in our pockets, and everybody seems to have forgotten that all these other maps exist, even though they clearly use them on a regular basis,” says Daniel Huffman, a cartographer and an honorary fellow at the University of Wisconsin in Madison. “I don’t think there is much of a separate case to be made for paper maps versus paper newspapers or paper books.”

 

Privacy: Paper maps 

tell no tales

 

To the extent that people fret about privacy, paper maps also won’t track you.

Now, Apple emphasised privacy as part of its rollout for the latest iteration of Apple Maps: No sign-on is required, for example, and data collected by Maps while using the app, including search terms, navigation routing, and traffic information, is hidden behind random identifiers.

When you navigate somewhere using Google Maps, your every movement is often tracked, where it shows up inside Google’s somewhat controversial opt-in Location History feature. Those seeking more privacy can enable Incognito Mode, which will stop Google from saving your Maps search and navigation activities to your Google Account. The downside is you’ll lose some personalisation features, around such things as restaurant recommendations and traffic updates.

 

Using paper maps 

to plan

 

There’s just something about unfolding a map and laying it flat on a table. It’s at the same time visceral and visual. You get the size, sweep and perspective that’s typically lacking when you stare at a smallish screen or wait for the voice to tell you when to make the next turn.

You may mark up that map as you pore over it for sites you might want to visit. It could be for a trip soon to be taken, or it may represent the only manifestation of the dream of a trip yet to materialise beyond the map in your hand.

“My dividing line: paper maps for planning and GPS in transit,” says Marty Levine in Vancouver, Canada.

For some people, a map is memory. It rekindles something else, perhaps a cherished and tangible recollection of places they visited or once lived, or it lives as a representation of ancestral ties, like the birthplace of their parents or grandparents.

“My husband and I used a paper map to drive throughout Portugal during our honeymoon [in 2017],” says Andrea Schneider, who lives in Austin. The couple highlighted their route in orange and yellow, to mark alternate days.

At night, they’d review the “spectacular” high-speed toll roads and many tunnels they’d gone through and plot the next day’s route. Schneider says the map gave them a deeper insight into the country’s typography and highway system.

“This ‘old-school’ approach to an international road trip was more interesting, reliable and fun than depending upon Google Maps,” she says.

The map is currently tucked away in a box with other mementos from the Portugal trip, and Schneider says she plans to frame it one of these days.

“It’s a lovely keepsake and souvenir that can’t really be recreated via a GPS.”

In this rapidly evolving digital world, paper maps add a sense of permanence. Roads and streets change for sure, and no printed map can typically keep up with that pace of change. But printed maps aren’t just about plotting where you may be heading next. They’re as much about where you have been.

Parrots get probability, use stats to make choices

PARIS — Does Polly want a cracker? That all depends on statistics.

Parrots can learn to choose based on probability, making them the first animal outside of the great ape family that uses statistical modelling in their decision-making process, researchers said Tuesday.

Wildlife experts taught six kea, a species of large parrot native to New Zealand renowned for their intelligence, to play a variation of a game designed to test their statistical understanding.

The birds — Blofeld, Bruce, Loki, Neo, Plankton and Taz — were trained to associate black tokens with a food reward and orange pegs with none. 

During early tests, they used their beaks to pick up the black tokens and were given a treat. 

The researchers then displayed the pegs in clear jars, with differing ratios of black and orange, picked up one token from each and concealed them in their palms, before offering them to the birds.

The kea preferred tokens from the jars that had a relatively higher proportion of black to orange tokens, showing that they were playing the percentages. 

In addition, the kea showed a clear preference towards researchers who had previously demonstrated a “bias” towards picking more black tokens than orange. 

“We always knew that they seemed quite intelligent, so we weren’t too surprised to find that they could understand probabilities,” said Amalia Bastos, research assistant at the University of Auckland’s School of Psychology.

“What was most surprising is that they can integrate social or physical information into their probabilistic judgements,” she told AFP.

Bastos and her research team aren’t currently sure what evolutionary advantage is bestowed by the ability to recognise probability. 

But the trait was long thought to be the reserve of intelligent primates and humans, and shows the kea and possibly its relatives may not be so bird-brained, after all.

“Kea have the boldest personalities of all the bird species I have ever met,” said Bastos. 

“Each individual has their own quirky preferences and idiosyncrasies that we learn about when we work with them. They are curious and not at all shy, making them very easy to work with. 

“They have definitely outsmarted me on more than one occasion,” she added.

 

The time-tested and the trusted

By - Mar 05,2020 - Last updated at Mar 05,2020

While technology keeps moving on and up at increasingly high speed, and most of us, most of the time, try to follow the change, the time-tested, well-trusted products prove they are extremely popular and are still very much put to good use. Some people hold on to them until the very last breath of the products, that is until they are withdrawn from the market or they stop receiving technical support from their maker.

The market share that these “old” — all things being relative — items represent is far from being negligible. Just look at Microsoft Windows 7 system for example.

The company’s current version of its ruling operating system for small computers is Windows 10. It was introduced in 2015 and therefore is now in its sixth year of operation. One would think that by now its previous version, Windows 7, would be gone for good. Surprisingly (or maybe not), Win7 is still used by 29 per cent of the Windows base, according to Gregg Keizer from Computerworld.

The reason is simple: Win7 is fast, well tested, reliable and runs on a reasonable amount of resources when it comes to memory and processor. Most importantly, it is now in its 11th year! It is almost like a dear friend after such a long time. Those who have been satisfied with the system do not understand why they should dump it and move up to Win10. This is particularly true in businesses where large numbers of computers are running and where a change would represent a major financial investment and a time-consuming, exhausting re-learning process, sometimes without any justification.

The password is another “time-tested and trusted” tech item. There are countless reasons against using passwords, but perhaps as many in favour of using them, after all these years. The newer, smarter identification ways, mainly biometrics such as iris scan, fingerprints, face or voice recognition, are making significant progress and a large number of people have adopted them, but the good old password has not yet said its last word (no pun intended).

In a certain way passwords are like Win7 —people feel comfortable using them and they work all right in the end, despite imperfections and shortcomings.

And what to say when it comes to smartphones? Just think of the number of those whose device is more than three years old, despite better newer cameras and similar innovations. These are the majority of users. It is not only money that is preventing them from getting a newer handset, but also and perhaps mainly the fact that they have come to trust the equipment they have and that it has made its positive, strong impact on the market.

On the other hand, there are technology products that are different from everything else, that have an instant appeal from the very start, and that are therefore quickly adopted by the public. WhatsApp is a striking example and a perfect illustration of such products. With them there is no looking back, sticking to the old way, hesitating or waiting till they are well-tested.

For the vast majority of us WhatsApp was a case of love at first sight. To think that we’ve had it for almost ten years now! Statistics dating to seven months ago estimate that a mind-blowing 65 billion messages are exchanged on the celebrated mobile messenger application every day (cnet.com). Certainly nothing could be more “time-tested and trusted”.
