Facebook bets on small-scale connections, romance

SAN JOSÉ, California — Got a crush on another Facebook user? The social network will help you connect, as part of a revamp unveiled on Tuesday that aims to foster real-world relationships and make the platform a more intimate place for groups of friends.

The new features were introduced in a revamped Facebook app as the embattled social network embarks on a new strategy emphasising private communications and small groups.

“As the world gets bigger and more connected, we need that sense of intimacy more than ever,” Zuckerberg said as he opened the F8 developer conference for the social networking giant.

“That’s why I believe the future is private.”

The new app made available to US users Tuesday aims for a new direction for Facebook: It eliminates the blue background and offers a range of new ways to connect, in line with Zuckerberg’s vision to move away from the “digital town square” to a “digital living room”.

Facebook’s shift comes response to criticism over failing to curb misinformation and manipulation of the platform used by 2.3 billion people, and missteps on its handling of private user data.

“It can be hard to find your sense of purpose when you are connected to billions of people at the same time,” Zuckerberg told the developers gathered in San Jose, California.

“Privacy gives us the freedom to be ourselves.”

The redesigned application, to be followed by a new Facebook website, symbolises changes in how Facebook runs its business, Zuckerberg said.

“I know we don’t exactly have the strongest reputation on privacy right now, to put it lightly,” he said. “But I am committed to starting a new chapter for our product.”

 

Dogs and politics

 

Changes announced on Tuesday put groups at the centre of the experience and add dating, friend-making and events features intended to promote people getting together in real life, Facebook’s new app head Fidji Simo told AFP ahead of F8.

The redesign is meant to make it easier for users to take part in communities, whether based on friendships, family ties or common interests, according to Simo.

“It’s definitely part of Mark’s bigger vision,” she said.

The new design gives users more options for private and group connections.

While counterintuitive, Facebook sees the change as potentially bringing people with opposing political viewpoints together rather than separating them in “filter bubbles”.

“We are seeing that groups can bridge people across dividing lines,” Simo said.

“If you are a dog lover, you will find people who are dog lovers across all divides, political or otherwise,” she added.

A “Meet New Friends” feature being gradually rolled out will let users opt in to getting acquainted with others interested in fresh connections within shared communities.

An “Events” tab will expedite making real world, local plans with online friends.

 

Hidden crushes

 

Facebook also announced it is expanding a dating feature to 14 more countries including the Philippines, Singapore, Brazil and Chile.

A new feature called “Secret Crush” will let people signal which friends they are interested in romantically on a private crush list — only letting the object of their fancy know if the feeling is mutual.

“We think there is a lot of potential in developing these relationships,” Simo said.

“It’s all built with privacy in mind, and with the goal of building meaningfully long-term relationships and not just hookups.”

The ability for people in small groups to be able to communicate securely and privately is seen as essential to making the social network more intimate.

There are tens of millions of active groups on Facebook, and more than 400 million people belong to groups at the social network.

 

Leaner, faster Messenger

 

Separately, Facebook unveiled a Messenger app overhaul that makes the mobile software leaner, faster and more of an energy miser.

“We rewrote practically all of the code from scratch,” the head of Messenger, Stan Chudnovsky, told AFP.

“We made Messenger the fastest private communication hub on the planet.”

Features built into the new Messenger app, used by some 1.3 billion people, build on the social network’s broader vision of small-group-sharing in “virtual living rooms”, according to Chudnovsky.

Facebook also announced its Portal video call device would be available internationally — starting with Canada in June, and Europe later this year — and would allow calls over the WhatsApp messaging platform.

Meanwhile, the Oculus Rift S and Oculus Quest headsets, starting at $399, will begin shipping on May 21, expanding Facebook’s move into virtual reality and gaming, the company said.

LucasFilm and Oculus Studios will have a “Star Wars” themed “Vader Immortal” virtual reality game ready when the Quest launches, putting players face to face with the master of the dark side of the Force.

Keen sense of smell linked to longer life

Older adults with a poor sense of smell may die sooner than their counterparts who have keen olfactory abilities, a US study suggests. 

Researchers asked 2,289 adults, ages 71 to 82, to identify 12 common smells, awarding scores from zero to as high as 12 based on how many scents they got right. When they joined the study, none of the participants were frail: They could walk a quarter mile, climb 10 steps, and independently complete daily activities. 

During 13 years of follow-up, 1,211 participants died. 

Overall, participants with a weak nose were 46 per cent more likely to die by year 10 and 30 per cent more apt to pass away by year 13 than people with a good sense of smell, the study found. 

“The association was largely limited to participants who reported good-to-excellent health at enrollment, suggesting that poor sense of smell is an early and sensitive sign for deteriorating health before it is clinically recognisable,” said senior study author Honglei Chen of Michigan State University in East Lansing. 

“Poor sense of smell is likely an important health marker in older adults beyond what we have already known about [i.e., connections with dementia, Parkinson’s disease, poor nutrition, and safety hazards],” Chen said by email. 

People who started out the study in excellent or good health were 62 per cent more likely to die by year 10 when they had a poor sense of smell than when they had a keen nose, researchers report in the Annals of Internal Medicine. 

But smell didn’t appear to make a meaningful difference in mortality rates for people who were in fair to poor health at the start of the study. 

With a poor sense of smell, people were more likely to die of neurodegenerative and cardiovascular diseases, but not of cancer or respiratory conditions. 

Poor sense of smell may be an early warning for poor health in older age that goes beyond neurodegenerative diseases that are often signal the beginning of physical or mental decline, the results also suggest. 

Dementia or Parkinson disease explained only 22 per cent of the higher death risk tied to a poor sense of smell, while weight loss explained just six per cent of this connection, researchers estimated. That leaves more than 70 per cent of the higher mortality rates tied to a weak nose unexplained. 

The connection between a poor sense of smell and mortality risk didn’t appear to differ by sex or race or based on individuals’ demographic characteristics, lifestyle, and or chronic health conditions. 

One limitation of the study is that the older adult participants were relatively functional, making it possible results might differ for younger people or for frail elderly individuals, the study team writes. 

Researchers also only tested smell at one point in time, and they didn’t look at whether changes in olfactory abilities over time might influence mortality. Researchers also lacked data on certain medical causes of a weak nose such as nasal surgery or chronic rhinosinusitis that are not related to aging. 

“The take-home message is that a loss in the sense of smell may serve as a bellwether for declining health”, said Vidyulata Kamath of the Johns Hopkins University School of Medicine in Baltimore, co-author of an accompanying editorial. 

 “As we age, we may be unaware of declining olfactory abilities,” Kamath said by email. “Given this discrepancy, routine olfactory assessment in older adults may have clinical utility in screening persons at risk for illness, injury or disease for whom additional clinical work-up and/or intervention may be warranted.” 

Parents bring newborns to ER for many non-urgent reasons

One of the hardest things about being a new parent is figuring out when babies are so sick they need to go to the emergency room and when worrisome signs or symptoms might actually be perfectly normal, doctors say. 

Anxious parents bring babies to the ER for all kinds of things that could go either way like goopy eyes, concerns about how the stump from the cut umbilical cord looks, vomiting, strange looking stool, irregular breathing and jerky or unusual body movements, doctors write in the American Journal of Emergency Medicine. 

“Differences between potentially dangerous pathology and normal infant behaviour can be subtle,” said lead study author Zachary Drapkin of the University of Utah in Salt Lake City. 

“It can be helpful if parents are counselled about what to expect over the first few days of life,” Drapkin said by e-mail. “Many of these issues could very effectively be addressed with improved access to primary care.” 

Even for emergency department physicians, it can be challenging to distinguish normal infant signs, symptoms and behaviours from potentially life-threatening conditions, Drapkin and colleagues write. 

For example, babies with conjunctivitis, or goopy eye, need to be seen in the ER when the cause is an infection, the paper notes. Infection is more likely the culprit when there is lots of discharge and gunk. 

Normally, the umbilical stump left behind when the cord is cut at birth will turn black or brown and dry out before it falls off, typically within about one week. It can also have a foul smell like rotting fruit, the paper notes. But warmth, swelling, purulent discharge or a fever might indicate an infection that requires immediate medical attention. 

Nearly all babies spit up because their stomachs are so small, and this is not necessarily a problem as long babies are urinating, feeding and growing normally. Unlike spit-up, projectile vomit may be caused by medical problems that could warrant a trip to the ER, the paper notes. 

Infant stool, meanwhile, can be a greenish colour for babies who are fed formula and more of a mustard colour for breastfed infants, the doctors point out. Bloody or black stool after the newborn stage, however, might mean babies need to be checked for serious health problems like internal bleeding or bowel obstruction. 

Newborns can startle easily and have jittery movements in response to stimuli, and this is normal, the doctors note. But jitteriness or jerky movements that continue over time and are not in response to stimuli may mean there is a seizure problem or something else that requires an urgent check-up. 

Beyond the challenge of figuring out what infant health issues may be true emergencies, parents can also struggle to get same-day sick visits with paediatricians that could help them avoid a trip ER, said Rajesh Daftary of the University of California San Francisco and Zuckerberg San Francisco General Hospital. 

“It’s hard to estimate what number of emergency department visits by a newborn or infant could be averted with a same day visit, but it’s certainly the majority,” Daftary, who was not involved in the paper, said by e-mail. “The challenge is trying to obtain these same day appointments.” 

Nurse advice phone lines may help in some cases, but it can be hard for a clinician on the phone to make an assessment without directly examining a baby, Daftary added. 

“Urgent care clinics can be especially helpful if they are staffed by a physician or advanced practitioner [nurse practitioner, physician assistant] specialising in paediatric care,” Daftary added. “Without that level of experience, an urgent care physician may opt to transfer a child to an emergency department where a more thorough assessment can be performed.” 

Range Rover Evoque P250 AWD: Evoking a response

By - Apr 29,2019 - Last updated at Apr 29,2019

AMMAN — Somewhat controversial with Land Rover traditionalists when first launched in 2011, the compact Range Rover Evoque, however, popularised and broadened the brand’s appeal and accessibility to new group of consumers. 

If stark and different then, the original Evoque’s low, wide and heavily stylised design has gone on to inform virtually every Land Rover product since, including the recently launched second generation Evoque.

Introduced earlier this year with new technology, improved space, luxury and efficiency, the new Evoque closely follows the original’s basic design cues, albeit with a more bulging, rounded and haughty demeanor.

 

Rakish roofline

 

Slightly longer, taller and with a longer wheelbase for improved legroom, the new Evoque strongly resembles its predecessor, yet has a seemingly bigger and bulkier presence owing to a higher waistline, taller front and rear fascia and higher, slimmer lights. 

Replacing the outgoing model’s sharp angular lines and surfacing with bulbous body work, the new Evoque retains many reworked styling elements, including a slim grille and lights with a thin vent below; and an even larger

lower intake. Also present is a similar clamshell bonnet to lend a squinting and moody appearance to its LED matrix headlights.

Meanwhile bulging wheel-arches still interrupt a design element that trails off from the edge of the headlights, and from a side view, the new model retains the rakishly low coupe-like roofline with black pillars, although this time without the choice of a three-door coupe body style. 

Along with a higher waistline, the new Evoque features a more sharply rising ridged side line below its new pop-out door handles. From the rear, the new Evoque’s width is accentuated by wider rear lights and a huge lower bumper insert with faux exhaust ports, as driven with the sportier looking R-design package.

 

Subtle electrification

 

Powered by petrol and diesel versions of Jaguar Land Rover’s in-house developed 2-litre turbocharged 4-cylinder Ingenium engine in place of its predecessor’s similar Ford-sourced engine, the new Evoque uses a mild hybrid electric vehicle (MHEV) system for its most popular four-wheel-drive automatic gearbox models. 

Almost un-discernible in operation, the 48v MHEV system recovers kinetic deceleration energy and stores it in under-body batteries, which allows the engine to automatically switch off at under 17km/h when coming to a stop, and also powers an electric motor that assists the Evoque when accelerating and driving in heavy traffic.

Subtle and virtually undetectable, the Evoque’s electric assistance did; however, seem to compensate for expected turbo lag from idling with better immediate responsiveness than expected. 

Driven in the second to top specification P250 guise, the Evoque produces 245BHP at 5,500rpm and 269lb/ft torque throughout a broad, versatile and accessibly responsive 1,300-4,500rpm mid-range. 

Not much more powerful than its predecessor but somewhat heavier at  1,818kg, the Evoque P250’s MHEV system and slick-shifting 9-speed automatic gearbox with a broad range of ratios for performance, efficiency and versatility do make it slightly quicker and economic.

 

Settled and stable

 

A brisk drive with confident mid-range flexibility despite its heft, the Evoque P250 covers the 0-100km/h in 7.5-seconds, 80-120km/h in 5.1-seconds and is capable of 230km/h, but returns moderate 7.9l/100km fuel efficiency on the combined cycle. 

A refined drive with good sound insulation and a reassuringly stable ride at speed, the driven R-Dynamic package version was fitted with the second largest 20-inch alloy wheels and 235/50R20 tyres. 

Somewhat firm over rougher more damaged road segments and on gravel trails, this tyre option was fine on smoother roads and provided reasonable comfort over imperfections and gripped corners well. However, entry-level 18-inch wheels proved better on Jordanian roads.

Driven with fixed rate dampers rather than with optional adaptive dampers, the Evoque’s MacPherson strut front and integral link rear suspension with fluid-filled bushes were well set-up to provide a good mix of ride comfort, settled vertical control and good lateral body control through fast and tight corners for the vehicle’s height. 

Tidy into corners with little sign of under-steer, the Evoque was also reasonably agile for the segment and allowed one to easily shift weight to the rear outside wheel to tighten a cornering line. Meanwhile, its quick 2.31-turn electric-assisted steering was direct and refined, if somewhat clinical as driven with 20-inch wheels.     

 

Sophisticated solutions

 

Driving the front wheels under normal circumstances to minimise fuel consumption, the Evoque’s four-wheel-drive reengages the rear wheels for stability, traction and grip. 

Primarily designed for road use, but with genuine off-road ability, the Evoque is offered with numerous standard on- and off-road driver assistance systems, including adaptive control, steering assist, lane-keeping assist, blind spot monitoring and autonomous emergency braking. 

For off-road driving, the Evoque features Hill Descent, Gradient Release and All-Terrain Progress control systems, as well as a four mode Terrain Response system that leverages and adapts various driver aids, gearbox and throttle for different off-road conditions.

A classy and well-equipped vehicle with a good driving position, the Evoque has a pleasantly up-market feel and design as driven in the luxurious HSE trim level, with good quality materials used in the right places and sophisticated, uncluttered switchgear and infotainment screens. 

Spacious in the front, if slightly less so for tall and large occupants in the rear, the Evoque offers good front visibility, but addresses the less generous rear and over-shoulder visibility associated with its sharply descending roofline, ascending waistline and small glasshouse with a standard 360° reversing camera and high mounted rear camera for a wider view with the flick of a button. 

Optionally, a front mirror offers unrestricted views for off-road driving and maneuvering in tight confines.

Kids' cavities probably not caused by bad genes

By - Apr 27,2019 - Last updated at Apr 27,2019

Environmental factors appear to play a bigger role than genetics in shaping children’s risk for cavities, a study of Australian twins suggests. 

Researchers followed 345 twins from 24 weeks’ gestation through six years of age, when they all had dental checkups. At age six, 32 per cent of the kids had tooth decay and 24 per cent of the children had advanced cavities. 

To see how much genetics might shape the risk of cavities, researchers looked at how often both kids got cavities in pairs of identical twins — who have identical genetic variations — and fraternal twins — who typically share about half of their variations. 

The risk of both siblings developing any form of tooth decay or advanced cavities was similar for identical and fraternal pairs, suggesting that genetics doesn’t explain much of the risk for these oral health problems. 

“Therefore, risk factors seem to be mostly environmental and are potentially modifiable,” said lead study author Mihiri Silva of the University of Melbourne and the Murdoch Children’s Research Institute at Royal Children’s Hospital in Melbourne. 

“This might debunk the idea that individuals are genetically destined to have poor teeth and should drive us to find ways of addressing the risk factors that we know are important for dental health,” Silva said by e-mail. 

Worldwide, an estimated 60 to 90 per cent of school age children have tooth decay, potentially resulting in pain, infection and hospitalisation, researchers note in Pediatrics. Toothache can also result in school absence, poor nutrition, compromised growth and development and impaired quality of life for children and parents alike. 

Childhood cavities are also the strongest predictor of poor oral health in adulthood, the study team writes. 

While some previous research has called into question the role genetics may play in causing cavities, research to date hasn’t offered a clear picture of what role environmental or lifestyle factors might play in this risk. 

In the current study, both twins had cavities in 29 pairs; in another 33 pairs of twins, just one child was affected. 

Both kids had advanced cavities in 26 pairs of twins, and another 31 pairs had just one child with advanced cavities. 

Three environmental factors in particular appeared to impact the risk of cavities: maternal obesity, defects in tooth enamel mineralisation, and lack of community water fluoridation. 

The study wasn’t a controlled experiment designed to prove whether or how any of these factors might directly cause tooth decay or cavities. 

But it’s possible maternal obesity might influence kids’ risk of oral health problems due to shared dietary or lifestyle habits in the household or biological processes that influence susceptibility to dental problems, Silva said. Obese mothers, for example, might be more likely to feed kids unhealthy food that can contribute to cavities. 

Fluoridation of drinking water, meanwhile, has been proven to reduce the risk of cavities but isn’t universally available in public drinking water. 

And defects in tooth enamel mineralisation that lead to weak enamel that can easily break down and form cavities may start developing in the womb and early childhood. This may be caused by certain medications taken by women during pregnancy or by children early in life, as well as by poor nutrition and certain diseases in early childhood. 

The good news is environmental factors like this can be controlled to help improve oral health. 

 “Based on the findings from all the existing research — including ours — parents and families should focus on practicing healthy habits in general including a diet low in sugar and regular toothbrushing,” Silva advised. 

Defects in enamel “can be detected and treated early to reduce problems, so ensuring children have early dental check-ups starting at one year of age can minimise problems later”, Silva added. “Our study also shows that public health initiatives like community water fluoridation continue to be important for prevention of dental caries.”

One million species risk extinction due to humans — draft UN report

PARIS — Up to 1 million species face extinction due to human influence, according to a draft UN report obtained by AFP that painstakingly catalogues how humanity has undermined the natural resources upon which its very survival depends.

The accelerating loss of clean air, drinkable water, CO2-absorbing forests, pollinating insects, protein-rich fish and storm-blocking mangroves — to name but a few of the dwindling services rendered by Nature — poses no less of a threat than climate change, says the report, set to be unveiled May 6.

Indeed, biodiversity loss and global warming are closely linked, according to the 44-page Summary for Policymakers, which distills a 1,800-page UN assessment of scientific literature on the state of Nature.

Delegates from 130 nations meeting in Paris from April 29, will vet the executive summary line-by-line. Wording may change, but figures lifted from the underlying report cannot be altered.

“We need to recognise that climate change and loss of Nature are equally important, not just for the environment, but as development and economic issues as well,” Robert Watson, chair of the UN-mandated body that compiled the report, told AFP, without divulging its findings.

“The way we produce our food and energy is undermining the regulating services that we get from Nature,” he said, adding that only “transformative change” can stem the damage.

Deforestation and agriculture, including livestock production, account for about a quarter of greenhouse gas emissions, and have wreaked havoc on natural ecosystems as well. 

 

‘Mass extinction event’ 

 

The Intergovernmental Science-Policy Platform on Biodiversity and Ecosystem Services (IPBES) report warns of “an imminent rapid acceleration in the global rate of species extinction”.

The pace of loss “is already tens to hundreds of times higher than it has been, on average, over the last 10 million years”, it notes. 

“Half-a-million to a million species are projected to be threatened with extinction, many within decades.”

Many experts think a so-called “mass extinction event” — only the sixth in the last half-billion years — is already under way.

The most recent saw the end of the Cretaceous period some 66 million years ago, when a 10-kilometre-wide asteroid strike wiped out most lifeforms.

Scientists estimate that Earth is today home to some eight million distinct species, a majority of them insects.

A quarter of catalogued animal and plant species are already being crowded, eaten or poisoned out of existence.

The drop in sheer numbers is even more dramatic, with wild mammal biomass — their collective weight — down by 82 per cent. 

Humans and livestock account for more than 95 per cent of mammal biomass.

 

Population growth 

 

“If we’re going to have a sustainable planet that provides services to communities around the world, we need to change this trajectory in the next 10 years, just as we need to do that with climate,” noted WWF chief scientist Rebecca Shaw, formerly a member of the UN scientific bodies for both climate and biodiversity.

The direct causes of species loss, in order of importance, are shrinking habitat and land-use change, hunting for food or illicit trade in body parts, climate change, pollution and alien species such as rats, mosquitoes and snakes that hitch rides on ships or planes, the report finds.

“There are also two big indirect drivers of biodiversity loss and climate change — the number of people in the world and their growing ability to consume,” said Watson.

Once seen as primarily a future threat to animal and plant life, the disruptive impact of global warming has accelerated.

Shifts in the distribution of species, for example, will likely double if average temperature go up a notch from 1.5ºC to 2ºC.

So far, the global thermometer has risen 1ºC compared with mid-19th century levels. 

The 2015 Paris Agreement enjoins nations to cap the rise to “well below” 2ºC. But a landmark UN climate report in October said that would still be enough to boost the intensity and frequency of deadly heatwaves, droughts, floods and storms.

 

Global inequity 

 

Other findings in the report say three-quarters of land surfaces, 40 per cent of the marine environment, and 50 per cent of inland waterways across the globe have been “severely altered”. 

Many of the areas where Nature’s contribution to human wellbeing will be most severely compromised are home to indigenous peoples and the world’s poorest communities that are also vulnerable to climate change.

More than 2 billion people rely on wood fuel for energy, 4 billion rely on natural medicines, and more than 75 per cent of global food crops require animal pollination. 

Nearly half of land and marine ecosystems have been profoundly compromised by human interference in the last 50 years.

Subsidies to fisheries, industrial agriculture, livestock raising, forestry, mining and the production of biofuel or fossil fuel energy encourage waste, inefficiency and over-consumption. 

The report cautioned against climate change solutions that may inadvertently harm Nature.

The use, for example, of biofuels combined with “carbon capture and storage” — the sequestration of CO2 released when biofuels are burned — is widely seen as key in the transition to green energy on a global scale.

But the land needed to grow all those biofuel crops may wind up cutting into food production, the expansion of protected areas or reforestation efforts.

Women ‘better at hiding infidelity’

TOKYO — You cannot hide your lying eyes: scientists have revealed that women can judge whether a man is likely to be unfaithful just by looking at his face but men are less able to spot a cheating woman.

Researchers at the University of Western Australia took a group of 1,500 people and showed them pictures of 189 Caucasian adults (101 men and 88 women), having first asked them if they had been unfaithful to their partners.

Respondents were then asked to rank these faces on a scale of one to 10, where one is “not at all likely to be unfaithful” and 10 is “extremely likely” to play the field.

The result, published in the journal Royal Society Open Science, was that “both men and women were accurate in assessing men’s, but not women’s, likelihood to cheat and poach”.

The scientists wanted to examine not only whether men and women could spot potential infidelity in each other but also whether it was possible to detect a possible “poacher” of the same sex.

They cited research showing that 70 per cent of people across more than 50 cultures report an attempt to poach someone else’s partner and 60 per cent saying they were successful.

The results were “not as expected”, the scientists admitted. Men were able to spot potential poachers among other men but even when other women were judging, the female of the species was inscrutable.

“Taken together, both men and women showed above-chance accuracy for men’s faces but not women’s faces. Therefore, perceived unfaithfulness may indeed contain some kernel of truth in male faces,” the scientists wrote.

What makes women suspect men might sleep around? 

According to the survey, it mainly boils down to perceived masculinity, although the researchers came up with another unexpected result, suggesting it is not the best-looking men that play away the most.

“Surprisingly, even though more attractive men were rated as more unfaithful, they were less likely to engage in actual mate poaching,” the study said.

Despite the findings, one of the scientists involved in the report cautioned against jumping to conclusions on a first date.

Although men are marginally more likely to betray infidelity with their features, it is still difficult to spot possible cheats from one individual’s face, said Yong Zhi Foo.

“If we are to rely solely on our first impressions to detect cheaters/poachers, then we will make substantial errors,” Foo told AFP.

“Our results must not be taken to mean that first impressions can be used in any everyday situations,” he added.

Periodic online subscriptions add up

By - Apr 25,2019 - Last updated at Apr 25,2019

Do not underestimate online subscriptions that look not so expensive at first sight. They all add up in the end. Even a couple of dollars a month per account matter when you reach a significant number of subscriptions that you have to keep renewing and paying for, which is exactly the where we all are headed, whether we like it or not.

There is a major trend in the world of IT and it is about (not) buying software and services. And of course it is Internet-related. The big players in the game, and the smaller ones as well, do not want to let you do one-time purchases anymore, but rather to go for periodic subscriptions, monthly or yearly.

The two most notorious subscriptions were introduced by Adobe and Microsoft a few years ago. Adobe does not sell anymore lifetime software licenses, like it used to do for its leading applications like Photoshop and Illustrator; at least not when it comes to the latest versions. With the older ones, and provided you accept to live with that, you may be lucky and find a reseller that still has them in stock. Otherwise, and if you only want the latest and the very best, like Adobe CC Suite for example, only a periodic and rather expensive subscription will do. There is simply no other choice.

Microsoft is only just a little nicer. Whereas it strongly pushes you to use its Office 360 Suite (Word, Excel, etc.) through online subscriptions, you still have the option to buy regular, lifetime Office licences if you prefer.

The above two are but the tip of the iceberg. In addition to Adobe and MS-Office is a long, a very long list of services that now are very common and that more and more people are choosing to subscribe to every month.

If Adobe’s and Microsoft’s subscriptions are in the tens and hundreds of dollars, most of the other services are in the units only. Examples: Dropbox cloud storage professional is about $9 a month, just like Netflix video streaming. Spotify music streaming is a humble $5 and Amazon Prime $13. Bein TV sport channels vary but the cost averages $20 per month.

Teamviewer application, a very popular software frequently used to access other computers remotely, has also recently shifted from lifetime licensing to monthly subscriptions costing an average of $30 a month. Let us not forget our mobile phone and Internet monthly subscriptions, or the eventual ones to online newspapers that we may also have.

The list goes on and on and is extending every few months. Soon even the basic, essential MS-Windows operating is going to be on monthly subscription basis.

Analysing the cost of each service separately and evaluating its usefulness makes perfect sense, and in most cases it leads to the obvious conclusion: it is worth every dollar and it makes you save money in the end.

Indeed, one month of Netflix is less expensive than one evening out at the movies for two people. By letting you access other computers remotely, for whatever reason you may need to do that, Teamviewer makes you save not only precious time but direct, very tangible transportation cost.

The problem therefore is not in the feasibility or in the principle of subscribing to online services, but in the simple fact that you can easily reach $400 to $500 a month, in total subscriptions. This in no way is negligible for the typical, average household, given that it is only to use your computers, the Internet and to enjoy a little entertainment at home. Food, education, travel, rent, clothing, health expenses are not included! Just make sure you are aware of what is happening to you and you realise how much you are spending — or maybe saving.

At corporate level the IT industry is pushing businesses in the same direction, which is not to buy expensive and hard to maintain computer servers, but to subscribe to the cloud services that are slowly but surely replacing them. However, and contrary to families and households, big corporations have their accountants and auditors to remind them how much exactly they are spending.

Drinking water might help kids limit soda consumption

One in five US children and young adults do not drink any water at all on a typical day, and a new study suggests they consume almost twice as many calories from sodas and sugary drinks as young people who do drink water. 

On any given day, kids who did not drink water consumed an average of 93 more calories from sugar sweetened beverages like sodas and juice drinks than young people who did drink some water. 

“These results are important because sugar-sweetened beverage consumption has been linked to many negative health conditions for children, including weight gain, dental caries and type 2 diabetes,” said lead study author Asher Rosinger, director of the Water, Health and Nutrition Labora tory at Pennsylvania State University. 

“Water is the healthiest drink people can consume, which is critical” for physical and mental health, Rosinger said by e-mail. 

Sodas and other sugar-sweetened beverages add empty calories to children’s diets, and substituting water for these drinks can help minimise the risk that young people will become overweight or obese, Rosinger’s team notes in JAMA Paediatrics. 

For the current study, they examined dietary data collected from 2011 to 2016 on 8,400 kids and young adults ranging in age from two to 19 years old. On average, the survey participants were about 11 years old. 

Overall, they consumed about 132 calories a day of sodas and other sugary drinks, the study found. 

With any amount of water intake, kids’ average consumption of soda and sweet drinks dropped to 112 calories a day. 

Without any water, however, children’s average consumption of soda and sweetened beverages rose to 210 calories a day. 

Results did not appear to differ for boys versus girls, or based on family income levels. 

But race and ethnicity did appear to influence the interactions between water and soda consumption. 

When white children did not drink water, they averaged 237 calories a day from sugar sweetened beverages, compared with about 115 calories if they did drink water. 

Black youth who drank no water got 218 calories a day from sodas and sweet drinks, compared with 125 calories for water drinkers. 

And, Hispanic kids who did not drink water got 176 calories a day from sugar sweetened beverages, compared with 115 for water drinkers. 

The study was not a controlled experiment designed to prove whether or how drinking water might directly impact soda consumption, and it also was not set up to prove whether any negative health outcomes were directly caused by sugary drinks. 

Still, the results suggest that there may be an inverse relationship between kid’s sugary beverage intake and their water intake, said Christina Roberto, a researcher at the Perelman School of Medicine at the University of Pennsylvania. 

“Kids who aren’t drinking water are drinking more sugary drinks instead compared to kids who drink water,” Roberto, who was not involved in the study, said by e-mail. “That suggests that getting kids to drink more water might help reduce their consumption of unhealthy sugary drinks, and both of those are important goals for promoting children’s health.” 

Parents need to make sure kids understand the importance of drinking water, said Jennifer Emond, a researcher at the Geisel School of Medicine at Dartmouth College in Hanover, New Hampshire. 

“Parents should encourage their kids to limit [sugar-sweetened beverages], including flavoured waters and sports drinks, and to choose water instead,” Emond, who was not involved in the study, said by e-mail. 

“Schools have a lot of influence on teens’ beverage choices, too,” Emond said. “Schools need to create a physical and social environment where sugary drinks, including sports drinks and flavoured waters, are not promoted, and where water is the chosen beverage.” 

Robo-journalism gains traction in shifting media landscape

WASHINGTON — A text-generating “bot” nicknamed Tobi produced nearly 40,000 news stories about the results of the November 2018 elections in Switzerland for the media giant Tamedia — in just five minutes.

These kinds of artificial intelligence programmes — available for nearly a decade — are becoming more widespread as news organisations turn to them to produce stories, personalise news delivery and, in some cases, sift through data to find important news.

Tobi wrote on vote results for each of Switzerland’s 2,222 municipalities, in both French and, German, for the country’s largest media group, according to a paper presented last month at the Computation + Journalism conference in Miami.

A similar automated programme called Heliograf has enabled The Washington Post daily to cover some 500 election races, along with local sports and business, since 2014.

“We’ve seen a greater acceptance of the potential for artificial intelligence, or robo-journalism, in newsrooms around the world,” said Damian Radcliffe, a University of Oregon professor who follows consumer trends and business models for journalism.

“These systems can offer speed and accuracy and potentially support the realities of smaller newsrooms and the time pressures of journalists.”

News organisations say the bots are not intended to displace human reporters or editors, but rather to help free them from the most monotonous tasks, such as sports results and earnings reports.

Jeremy Gilbert, director of strategic initiatives at The Washington Post, said Heliograf was developed as a tool to help the newspaper’s editorial team.

“The Post has an incredible team of reporters and editors and we didn’t want to replace them,” Gilbert told AFP.

‘Is this something we can automate?’

 

Gilbert said the bot can deliver and update stories more quickly as they develop, allowing reporters to concentrate on other tasks, and that reaction has been generally positive.

“The surprise was that a lot of people came up and said, ‘I do this story every week; is this something we can automate?’” Gilbert said.

“These weren’t stories that anyone wanted to do.”

Similar conversations are going on in newsrooms around the world. The Norwegian news agency NTB automated sports reports to get match results delivered within 30 seconds.

The Los Angeles Times developed a “quakebot” that quickly distributes news articles on temblors in the region and also uses an automated system as part of its Homicide Report.

The Associated Press has been automating quarterly earnings reports for some 3,000 listed companies, allowing the news agency to expand from what had been just a few hundred, and this year announced plans with its partner Automated Insights to deliver computer-generated previews of college basketball games.

Rival news agency Reuters last year announced the launch of Lynx Insight, which uses automated data analysis to identify trends and anomalies and to suggest stories reporters should write. 

Bloomberg’s computerised system called Cyborg “dissects a company’s earnings the moment they appear” and produces within seconds a “mini-wrap with all the numbers and a lot of context”, editor-in-chief John Micklethwait wrote last year, noting that one-fourth of the agency’s content “has some degree of automation”.

France’s Le Monde and its partner Syllabs deployed a computer programme that generated 150,000 web pages covering 36,000 municipalities in the 2015 elections.

One advantage of using algorithmically generated stories is that they can also be “personalised”, or delivered to the relevant localities, which can be useful for elections and sports coverage. 

 

Investigative

 robo-reporter?

 

While news professionals acknowledge the limits of computer programmes, they also note that automated systems can sometimes accomplish things humans can’t.

The Atlanta Journal-Constitution used a data journalism team to uncover 450 cases of doctors who were brought before medical regulators or courts for sexual misconduct, finding that nearly half remained licensed to practice medicine.

The newspaper used machine learning, an artificial intelligence tool, to analyse each case and assign a “probability rating” on sexual misconduct, which was then reviewed by a team of journalists.

Studies appear to indicate consumers accept computer-generated stories, which are mostly labelled as such.

A report prepared by researcher Andreas Graefe for Columbia University’s Tow Centre said one study of Dutch readers found that the label of computer-generated “had no effect on people’s perceptions of quality”.

A second study of German readers, Graefe said, found that “automated articles were rated as more credible”, although human-written news scored higher for “readability”.

 

Robot apocalypse?

 

Even though journalists and robots appear to be helping each other, fears persist about artificial intelligence spinning out of control and costing journalists’ jobs.

In February, researchers at the non-profit centre OpenAI announced they had developed an automatic text generator so good that it is keeping details private for now.

The researchers said the programme could be used for nefarious purposes, including to generate fake news articles, impersonating others online, and automate fake content on social media.

But Meredith Broussard, a professor of data journalism at New York University, said she does not see any immediate threats of robots taking over newsrooms.

She said there are many positive applications of artificial intelligence in the newsroom, but that for now, most programmes handle “the most boring” stories.

“There are some jobs that are going to be automated, but overall, I’m not worried about the robot apocalypse in the newsroom,” she said.
