The Whatsapp-inspired, Facebook-investor funded app tackling India’s doctor shortage

Curated on March 4, 2017October 9, 2018 by Stefaan Verhulst

Kylee McIntyre at TechInAsia: “A problem beyond India’s low doctor-to-patient ratio is the distribution of those doctors. Most, particularly specialists, congregate in bigger cities and get seen by patients in the surrounding areas. Only 19 percent of specialists are available in community health centers across India, and most fall well below the country’s requirement for specialists. Community health centers are located in smaller towns and help patients in the area decide if they need to visit a larger, better-equipped city facility….

The IIT-Madras grad’s company, DocsApp, co-founded with fellow IIT-Madras alum Enbasekar D (CTO), joins startups like Practo, DocDoc, and Medinfi in helping patients find physicians. However, the app’s main focus is specialists, and it lets patients chat with doctors and get consultations.

DocsApp’s name is directly inspired by WhatsApp. As long as you have a chat screen on your phone, you can input your problems and location, find a doctor, and ask questions. A user can pay for his or her own appointment over mobile. If treatment requires a physical visit, the user’s money is refunded….

Doctor profiles include the physician’s experience, medical counsel ID, patient reviews, specialty, and languages – DocsApp covers 17 different languages. DocsApp has 1,200 doctors in 15 specialties. All doctors on the platform are verified by looking up certification, an interview, and a facilities review.

If a consultation reveals that a patient needs a prescription, the doctor can provide a digitally-signed e-prescription. DocsApp can deliver medicines within two days to any location in India, says Satish.

Once a user has access to one of the doctors, he or she can message the doctor 24/7 and get a response in 30 minutes – Satish says that the company’s average is now 18 minutes. The team of 55 is aiming for a minute or less….

Telemedicine is one of the ways tech is combatting India’s doctor shortage. Other startups in the industry in the country include Visit, which focuses on both physical and mental health, and SeeDoc, a physician video consultation app.

A chat is a little less personal than a physical visit, which can open the door for patients who want to discuss more taboo topics in India, like mental health and fertility questions. Satish adds that women who live in locations where it’s best to be accompanied by a man when going out also find convenience, as they don’t necessarily need to wait for a husband to come back from work before addressing a medical question she has about her child…(More)”.

Restoring Trust in Expertise

Curated on March 4, 2017July 19, 2019 by Stefaan Verhulst

Minouche Shafik at Project Syndicate: “…public confidence in experts is at a crossroads. With news becoming more narrowly targeted to individual interests and preferences, and with people increasingly choosing whom to trust and follow, the traditional channels for sharing expertise are being disrupted. Who needs experts when you have Facebook, Google, Mumsnet, and Twitter?

Actually, we all do. Over the course of human history, the application of expertise has helped tackle disease, reduce poverty, and improve human welfare. If we are to build on this progress, we need reliable experts to whom the public can confidently turn.

Restoring confidence requires, first, that those describing themselves as “experts” embrace uncertainty. Rather than pretending to be certain and risk frequently getting it wrong, commentators should be candid about uncertainty. Over the long term, such an approach will rebuild credibility. A good example of this is the use of “fan charts” in forecasts produced by the Bank of England’s Monetary Policy Committee (MPC), which show the wide range of possible outcomes for issues such as inflation, growth, and unemployment.

Yet conveying uncertainty increases the complexity of a message. This is a major challenge. It is easy to tweet “BoE forecasts 2% growth.” The fan chart’s true meaning – “If economic circumstances identical to today were to prevail on 100 occasions, the MPC’s best collective judgment is that the mature estimate of GDP growth would lie above 2% on 50 occasions and below 2% on 50 occasions” – doesn’t even fit within Twitter’s 140-character limit.

This underscores the need for sound principles and trustworthy practices to become more widespread as technology changes the way we consume information. Should journalists and bloggers be exposed for reporting or recirculating falsehoods or rumors? Perhaps principles and practices widely used in academia – such as peer review, competitive processes for funding research, transparency about conflicts of interests and financing sources, and requirements to publish underlying data – should be adapted and applied more widely to the world of think tanks, websites, and the media….

Schools and universities will have to do more to educate students to be better consumers of information. Striking research by the Stanford History Education Group, based on tests of thousands of students across the US, described as “bleak” their findings about young people’s ability to evaluate information they encounter online. Fact-checking websites appraising the veracity of claims made by public figures are a step in the right direction, and have some similarities to peer review in academia.

Listening to the other side is crucial. Social media exacerbates the human tendency of groupthink by filtering out opposing views. We must therefore make an effort to engage with opinions that are different from our own and resist algorithmic channeling to avoid difference. Perhaps technology “experts” could code algorithms that burst such bubbles.

Finally, the boundary between technocracy and democracy needs to be managed more carefully. Not surprisingly, when unelected individuals steer decisions that have huge social consequences, public resentment may not be far behind. Problems often arise when experts try to be politicians or politicians try to be experts. Clarity about roles – and accountability when boundaries are breached – is essential.

We need expertise more than ever to solve the world’s problems. The question is not how to manage without experts, but how to ensure that expertise is trustworthy. Getting this right is vital: if the future is not to be shaped by ignorance and narrow-mindedness, we need knowledge and informed debate more than ever before….(More)”.

When the Big Lie Meets Big Data

Curated on March 4, 2017August 3, 2018 by Stefaan Verhulst

Peter Bruce in Scientific America: “…The science of predictive modeling has come a long way since 2004. Statisticians now build “personality” models and tie them into other predictor variables. … One such model bears the acronym “OCEAN,” standing for the personality characteristics (and their opposites) of openness, conscientiousness, extroversion, agreeableness, and neuroticism. Using Big Data at the individual level, machine learning methods might classify a person as, for example, “closed, introverted, neurotic, not agreeable, and conscientious.”

Alexander Nix, CEO of Cambridge Analytica (owned by Trump’s chief donor, Rebekah Mercer), says he has thousands of data points on you, and every other voter: what you buy or borrow, where you live, what you subscribe to, what you post on social media, etc. At a recent Concordia Summit, using the example of gun rights, Nix described how messages will be crafted to appeal specifically to you, based on your personality profile. Are you highly neurotic and conscientious? Nix suggests the image of a sinister gloved hand reaching through a broken window.

In his presentation, Nix noted that the goal is to induce behavior, not communicate ideas. So where does truth fit in? Johan Ugander, Assistant Professor of Management Science at Stanford, suggests that, for Nix and Cambridge Analytica, it doesn’t. In counseling the hypothetical owner of a private beach how to keep people off his property, Nix eschews the merely factual “Private Beach” sign, advocating instead a lie: “Sharks sighted.” Ugander, in his critique, cautions all data scientists against “building tools for unscrupulous targeting.”

The warning is needed, but may be too late. What Nix described in his presentation involved carefully crafted messages aimed at his target personalities. His messages pulled subtly on various psychological strings to manipulate us, and they obeyed no boundary of truth, but they required humans to create them. The next phase will be the gradual replacement of human “craftsmanship” with machine learning algorithms that can supply targeted voters with a steady stream of content (from whatever source, true or false) designed to elicit desired behavior. Cognizant of the Pandora’s box that data scientists have opened, the scholarly journal Big Data has issued a call for papers for a future issue devoted to “Computational Propaganda.”…(More)”

Facebook artificial intelligence spots suicidal users

Curated on March 2, 2017August 3, 2018 by Stefaan Verhulst

Leo Kelion at BBC News: “Facebook has begun using artificial intelligence to identify members that may be at risk of killing themselves.

The social network has developed algorithms that spot warning signs in users’ posts and the comments their friends leave in response.

After confirmation by Facebook’s human review team, the company contacts those thought to be at risk of self-harm to suggest ways they can seek help.

A suicide helpline chief said the move was “not just helpful but critical”.

The tool is being tested only in the US at present.

It marks the first use of AI technology to review messages on the network since founder Mark Zuckerberg announced last month that he also hoped to use algorithms to identify posts by terrorists, among other concerning content.

Facebook also announced new ways to tackle suicidal behaviour on its Facebook Live broadcast tool and has partnered with several US mental health organisations to let vulnerable users contact them via its Messenger platform.

Pattern recognition

Facebook has offered advice to users thought to be at risk of suicide for years, but until now it had relied on other users to bring the matter to its attention by clicking on a post’s report button.

It has now developed pattern-recognition algorithms to recognise if someone is struggling, by training them with examples of the posts that have previously been flagged.

Talk of sadness and pain, for example, would be one signal.

Responses from friends with phrases such as “Are you OK?” or “I’m worried about you,” would be another.

Once a post has been identified, it is sent for rapid review to the network’s community operations team.

“We know that speed is critical when things are urgent,” Facebook product manager Vanessa Callison-Burch told the BBC.

The director of the US National Suicide Prevention Lifeline praised the effort, but said he hoped Facebook would eventually do more than give advice, by also contacting those that could help….

The latest effort to help Facebook Live users follows the death of a 14-year-old-girl in Miami, who livestreamed her suicide on the platform in January.

However, the company said it had already begun work on its new tools before the tragedy.

The goal is to help at-risk users while they are broadcasting, rather than wait until their completed video has been reviewed some time later….(More)”.

Fighting Illegal Fishing With Big Data

Curated on March 1, 2017August 3, 2018 by Stefaan Verhulst

Emily Matchar in Smithsonian: “In many ways, the ocean is the Wild West. The distances are vast, the law enforcement agents few and far between, and the legal jurisdiction often unclear. In this environment, illegal activity flourishes. Illegal fishing is so common that experts estimate as much as a third of fish sold in the U.S. was fished illegally. This illegal fishing decimates the ocean’s already dwindling fish populations and gives rise to modern slavery, where fishermen are tricked onto vessels and forced to work, sometimes for years.

A new use of data technology aims to help curb these abuses by shining a light on the high seas. The technology uses ships’ satellite signals to detect instances of transshipment, when two vessels meet at sea to exchange cargo. As transshipment is a major way illegally caught fish makes it into the legal supply chain, tracking it could potentially help stop the practice.

“[Transshipment] really allows people to do something out of sight,” says David Kroodsma, the research program director at Global Fishing Watch, an online data platform launched by Google in partnership with the nonprofits Oceana and SkyTruth. “It’s something that obscures supply chains. It’s basically being able to do things without any oversight. And that’s a problem when you’re using a shared resource like the oceans.”

Global Fishing Watch analyzed some 21 billion satellite signals broadcast by ships, which are required to carry transceivers for collision avoidance, from between 2012 and 2016. It then used an artificial intelligence system it created to identify which ships were refrigerated cargo vessels (known in the industry as “reefers”). They then verified this information with fishery registries and other sources, eventually identifying 794 reefers—90 percent of the world’s total number of such vessels. They tracked instances where a reefer and a fishing vessel were moving at similar speeds in close proximity, labeling these instances as “likely transshipments,” and also traced instances where reefers were traveling in a way that indicated a rendezvous with a fishing vessel, even if no fishing vessel was present—fishing vessels often turn off their satellite systems when they don’t want to be seen. All in all there were more than 90,000 likely or potential transshipments recorded.

Even if these encounters were in fact transshipments, they would not all have been for nefarious purposes. They may have taken place to refuel or load up on supplies. But looking at the patterns of where the potential transshipments happen is revealing. Very few are seen close to the coasts of the U.S., Canada and much of Europe, all places with tight fishery regulations. There are hotspots off the coast of Peru and Argentina, all over Africa, and off the coast of Russia. Some 40 percent of encounters happen in international waters, far enough off the coast that no country has jurisdiction.

The tracked reefers were flying flags from some 40 different countries. But that doesn’t necessarily tell us much about where they really come from. Nearly half of the reefers tracked were flying “flags of convenience,” meaning they’re registered in countries other than where the ship’s owners are from to take advantage of those countries’ lax regulations….(More)”

Denmark is appointing an ambassador to big tech

Curated on February 27, 2017August 3, 2018 by Stefaan Verhulst

Matthew Hughes in The Next Web: “Question: Is Facebook a country? It sounds silly, but when you think about it, it does have many attributes in common with nation states. For starters, it’s got a population that’s bigger than that of India, and its 2016 revenue wasn’t too far from Estonia’s GDP. It also has a ‘national ethos’. If America’s philosophy is capitalism, Cuba’s is communism, and Sweden’s is social democracy, Facebook’s is ‘togetherness’, as corny as that may sound.

Given all of the above, is it really any surprise that Denmark is considering appointing a ‘big tech ambassador’ whose job is to establish and manage the country’s relationship with the world’s most powerful tech companies?

Denmark’s “digital ambassador” is a first. No country has ever created such a role. Their job will be to liase with the likes of Google, Twitter, Facebook.

Given the fraught relationship many European countries have with American big-tech – especially on issues of taxation, privacy, and national security – Denmark’s decision to extend an olive branch seems sensible.

Speaking with the Washington Post, Danish Foreign Minister Anders Samuelsen said, “just as we engage in a diplomatic dialogue with countries, we also need to establish and prioritize comprehensive relations with tech actors, such as Google, Facebook, Apple and so on. The idea is, we see a lot of companies and new technologies that will in many ways involve and be part of everyday life of citizens in Denmark.”….(More)”

Why We Make Free, Public Information More Accessible

Curated on February 18, 2017August 3, 2018 by Stefaan Verhulst

Gabi Fitz and Lisa Brooks in Philantopic: “One of the key roles the nonprofit sector plays in civil society is providing evidence about social problems and their solutions. Given recent changes to policies regarding the sharing of knowledge and evidence by federal agencies, that function is more critical than ever.

Nonprofits deliver more than direct services such as running food banks or providing shelter to people who are homeless. They also collect and share data, evidence, and lessons learned so as to help all of us understand complex and difficult problems.

Those efforts not only serve to illuminate and benchmark our most pressing social problems, they also inform the actions we take, whether at the individual, organizational, community, or policy level. Often, they provide the evidence in “evidence-based” decision making, not to mention the knowledge that social sector organizations and policy makers rely on when shaping their programs and services and individual citizens turn to inform their own engagement.

In January 2017, several U.S. government agencies, including the Environmental Protection Agency and the Departments of Health and Human Services and Agriculture, were ordered by officials of the incoming Trump administration not to share anything that could be construed as controversial through official communication channels such as websites and social media channels. (See “Federal Agencies Told to Halt External Communications.”) Against that backdrop, the nonprofit sector’s interest in generating and sharing evidence has become more urgent than ever…..

Providing access to evidence and lessons learned is always important, but in light of recent events, we believe it’s more necessary than ever. That’s why we are asking for your help in providing — and preserving — access to this critical knowledge base.

Over the next few months, we will be updating and maintaining special collections of non-academic research on the following topics and need lead curators with issue expertise to lend us a hand. IssueLab special collections are an effort to contextualize important segments of the growing evidence base we curate, and are one of the ways we help visitors to the platform learn about nonprofit organizations and resources that may be useful to their work and knowledge-gathering efforts.

Possible special collection topics to be updated or curated:

→ Access to reproductive services (new)

→ Next steps for ACA

→ Race and policing

→ Immigrant detention and deportation

→ Climate change and extractive mining (new)

→ Veterans affairs

→ Gun violence

If you are a researcher, knowledge broker, or service provider in any of these fields of practice, please consider volunteering as a lead curator. …(More)”
