What can we learn from billions of food purchases derived from fidelity cards?

Curated on Posted on by Stefaan Verhulst

Daniele Quercia at Medium: “By combining 1.6B food item purchases with 1.1B medical prescriptions for the entire city of London for one year, we discovered that, to predict health outcomes, socio-economic conditions matter less than what previous research has shown: despite being of lower-income, certain areas are healthy, and that is because of what their residents eat!

This result comes from our latest project “Poor but Healthy”, which was published in the Springer European Physical Journal (EPJ) of Data Science this month, and comes with a @tobi_vierzwo’s stunningly beautiful map of London I invite all of you to explore.

Why are we interested in urban health? In our cities, food is cheap and exercise discretionary, and health takes its toll. Half of European citizens will be obese by 2050, and obesity and its diseases are likely to reach crisis proportions. In this project, we set out to show that fidelity cards of grocery stores represent a treasure trove of health data — they can be used not only to (e)mail discount coupons to customers but also to effectively track a neighbourhood’s health in real-time for an entire city or even an entire country.

In research circles, the impact of eating habits on people’s health has mostly been studied using dietary surveys, which are costly and of limited scale.

To complement these surveys, we have recently resorted to grocery fidelity cards. We analyzed the anonymized records of 1.6B grocery items purchased by 1.6M grocery store customers in London over one whole year, and combined them with 1.1B medical prescriptions.

In so doing, we found that, as one expects, the “trick” to not being associated with chronic diseases is eating less what we instinctively like (e.g., sugar, carbohydrates), balancing all the nutrients, and avoiding the (big) quantities that are readily available. These results come as no surprise yet speak to the validity of using fidelity cards to capture health outcomes…(More)”.


Microsoft’s Open Notre Dame initiative calls for sharing of open data in restoration effort

Curated on Posted on by Stefaan Verhulst

Hamza Jawad at Neowin: “On April 15, a disastrous fire ravaged the famous Notre-Dame cathedral in France. In the wake of the episode, tech companies, such as Apple, announced that they would be donating to help in rebuilding efforts. On the other hand, some companies, like Ubisoft, took a different approach to support the restorations that followed.

A few days ago, Microsoft and Iconem announced the “Open Notre Dame” initiative to contribute towards the restoration of the ‘Lady of Paris’. The open data project is said to help gather and analyze existing documents on the monument, while simultaneously producing and sharing its 3D models. Today, the company has once again detailed the workings of this initiative, along with a call for the sharing of open data to help quicken the restoration efforts….

GitHub will host temporal models of the building, which can then be easily shared to and accessed by various other initiatives in a concerted effort to maintain accuracy as much as possible. Many companies, including Ubisoft, have already provided data that will help form the foundation for these open source models. More details regarding the project can be obtained on the original blog post….(More)”.

Government support is a key factor for civic technology

Curated on Posted on by Stefaan Verhulst

Blog Post by Rebecca Rumbul: “Civic tech is on a huge growth curve. There is much more of it about now than there was ten years ago. At the same time, it is changing the scope and reach, and becoming much more mainstream. Ten years ago civic tech was hardly spoken about by anyone. It was largely the domain of ‘outsiders’, by which I mean campaigners and data specialists working outside the mainstream. Today civic tech is an accepted, respected and widely used form of engaging citizens.

The movement over that ten years has mostly been gradual, but over the last couple of years, there has been a really significant shift in how civic tech is viewed both by those within and outside the sector. A wider range of funders are more interested in supporting projects, government seems to have woken up to how civic tech can really be a spur to public engagement, and the word is getting out there to people on the street. Quite literally. At mySociety our FixMyStreet app now garners in the region of six thousand citizen reports of things like potholes and fly-tipping every week.

This maturing of attitudes towards and use of civic tech is wonderful to see. Those pioneers who saw a problem wrote a bit of code and put it online as a way of immediately finding a way to fix the problem have seen their often locally focused efforts contribute to the growth of a global phenomenon in a really short space of time.  And we are in a process here. There is no doubt that civic tech continues to grow and continues to make an impact way beyond its humble beginnings.

But the way civic tech develops is not uniform around the world, and it does need a number of circumstances to converge to make it really sing. That coming together of citizen awareness, government buy-in and funding support is crucial to its success. And there are other important factors too.

We’ve been researching the impact of civic tech around the world, and one of the most interesting things we’ve learned is that the movement is working with institutions much more today than it did five or ten years ago…(More)“.

Living Labs As A Collaborative Framework For Changing Perceptions And Goals

Curated on Posted on by Stefaan Verhulst

Co-Val: “In the… ‘Report on cross-country comparison on existing innovation and living labs’, Lars Fuglsang and Anne Vorre Hansen from Roskilde University describe various applications of living labs to decision-making. The basic two examples are living labs as a collaborative framework for changing perceptions and goals and living labs as an ecosystem for policy innovation.

Living labs can involve a change in mindset and goals as expressed in one paper on public sector innovation labs (Carstensen & Bason, 2012). Carstensen and Bason (2012) report the important story of the Danish Mindlab (2002-2018) – a cross-governmental innovation lab involving public sector organisations, citizens and businesses in creating new solutions for society. They argue that innovation labs are designed to foster collaboration since labs are platforms where multiple stakeholders can engage in interaction, dialogue, and development activities.  Innovation needs a different approach than everyday activities and a change in mindset and culture shift of employees towards thinking more systematically about innovation. Mindlab’s methodologies are anchored in design thinking, qualitative research and policy development, with the aim of capturing the subjective reality experienced by both citizens and businesses in the development of new solutions. Carstensen and Bason (2012) list the following key principles of Mindlab: take charge of on-going renewal, maintain top management backing, create professional empathy, insist on collaboration, do – don’t just think, recruit and develop likeable people, don’t be too big, communicate.

Also, Buhr et al. (2016) show how living labs can be important for developing and implementing collective goals and creating new opportunities for citizens to influence public affairs. They describe two cases in two suburban areas (located in Sweden and Finland), where the living lab approach was used to improve the feeling of belonging in a community. In one of the two suburbs studied, a living lab approach was used to change the lightning on a pathway that seemed unsafe; and in the other case, a living lab approach was used to strengthen the social community by renovating a kiosk and organizing varied activities for the citizens. Both living labs motivated the residents to work on societal goals for sustainability and choose solutions. The study indicates that a living lab approach can be used for gaining support for change and thereby increasing the citizens’ appreciation of a local area. Further, living labs may give citizens a feeling that they are being listened to. Living labs can thus create opportunities for citizens to develop the city together with municipal policy-makers and other stakeholders and enable policy-makers to respond to the expressed needs of the citizens….(More)”

Collab: A new digital tool for community participation

Curated on Posted on by Stefaan Verhulst

Sidewalk Labs: “The long-term success of a neighborhood is predicated on its community members feeling a sense of ownership and belonging — of believing that, together, they are the stewards of their community. But it’s increasingly rare for 21st century city residents to join in the shared project of shaping their neighborhoods. Stop to consider: when was the last time you attended a community meeting? Volunteered at a neighborhood charity? Called your local representative? For many of us, the answer is never.

While there are many reasons for this decline in civic participation, one contributing factor is transparency. It’s not always clear how input will be used or if the organizations charged with community decisions are able to receive and act on that feedback. Another factor is that people may not always feel they are sufficiently knowledgeable on certain issues to meaningfully contribute.

To help address these challenges, governments and companies around the world have begun building tools that leverage technology to make participation more informed, transparent, and relevant to people’s daily lives.

The City of Barcelona is at the forefront of this trend, having created Decidim, an open-source digital tool inspired by social media that keeps residents up to date on processes and garners their input (the tool has since spread globally). The City of Bologna recently launched an Office of Civic Imaginationdesigned specifically to build greater participation through regulation, engagement labs throughout the city, and digital tools. Startups are also getting into the mix, such as Neighborland, which offers a customizable platform for engagement between city planners and communities. And some communities have even started creating their own tools, such as YouthScore, which allows youth to rate their neighborhoods based on their youth friendliness.

These examples are part of a promising trajectory towards inclusive digital participation that could enable people to engage with and enhance the places where they live, work, and visit. We’re excited by the idea of a future where community members can easily influence the decisions, spaces, and technologies that impact them — and where decision-making entities can be even more responsive to community input.

Our hope is that these tools kickstart a virtuous cycle: the more community members feel empowered to shape their communities, the more they will participate. The more they participate, the more decision-makers can be enabled to be more inclusive and responsive to community voices, inspiring more community members to participate. And so on.

As Barcelona, Bologna, and Neighborland show, there are many different ways that digital tools — in coordination with strong in-person and more traditional approaches — can unlock civic participation. One promising approach is leveraging technology to bring transparency into processes and decision points that could allow community members to better understand the issues at hand, provide input, and, hopefully, feel satisfied that their voices have been heard. What’s more, we believe that by providing community members with an informed, nuanced understanding of the required trade-offs of a decision, digital tools could even encourage more decisions that put collective good ahead of individual interests.

So we decided to create a prototype — one small contribution towards a more civically-engaged urban future.

Creating Collab

As a first step, we partnered with Digital Public Square, a Toronto-based non-profit that works globally to rethink and redesign how to leverage technology to support communities. Together, we came up with the idea for Collab, a digital tool that could support communities hoping to increase participation and make more inclusive, collaborative decisions….(More)”.

The death of the literature review and the rise of the dynamic knowledge map

Curated on Posted on by Stefaan Verhulst

Gorgi Krlev at LSE Impact Blog: “Literature reviews are a core part of academic research that are loathed by some and loved by others. The LSE Impact Blog recently presented two proposals on how to deal with the issues raised by literature reviews: Richard P. Phelps argues, due to their numerous flaws, we should simply get rid of them as a requirement in scholarly articles. In contrast, Arnaud Vaganay proposes, despite their flaws, we can save them by means of standardization that would make them more robust. Here, I put forward an alternative that strikes a balance between the two: Let’s build databases that help systemize academic research. There are examples of such databases in evidence-based health-care, why not replicate those examples more widely?

The seed of the thought underlying my proposition of building dynamic knowledge maps in the social sciences and humanities was planted in 2014. I was attending a talk within Oxford’s evidence-based healthcare programme. Jon Brassey, the main speaker of the event and founder of the TRIP database, was explaining his life goal: making systematic reviews and meta-analyses in healthcare research redundant! His argument was that a database containing all available research on treatment of a symptom, migraine for instance, would be able to summarize and display meta-effects within seconds, whereas a thorough meta-analysis would require weeks, if not months, if done by a conventional research team.

Although still imperfect, TRIP has made significant progress in realizing this vision. The most recent addition to the database are “evidence maps” that visualize what we know about effective treatments. Evidence maps compare alternative treatments based on all available studies. They indicate effectiveness of a treatment, the “size” of evidence underscoring the claim and the risk of bias contained in the underlying studies. Here and below is an example based on 943 studies, as of today, dealing with effective treatment of migraine, indicating aggregated study size and risk of bias.

Source: TRIP database

There have been heated debates about the value and relevance of academic research (propositions have centred on intensifying research on global challenges or harnessing data for policy impact), its rigor (for example reproducibility), and the speed of knowledge production, including the “glacial pace of academic publishing”. Literature reviews, for the reasons laid out by Phelps and Vaganay, suffer from imperfections that make them: time consuming, potentially incomplete or misleading, erratic, selective, and ultimately blurry rather than insightful. As a result, conducting literature reviews is arguably not an effective use of research time and only adds to wider inefficiencies in research….(More)”.

How AI could save lives without spilling medical secrets

Curated on Posted on by Stefaan Verhulst

Will Knight at MIT Technology Review: “The potential for artificial intelligence to transform health care is huge, but there’s a big catch.

AI algorithms will need vast amounts of medical data on which to train before machine learning can deliver powerful new ways to spot and understand the cause of disease. That means imagery, genomic information, or electronic health records—all potentially very sensitive information.

That’s why researchers are working on ways to let AI learn from large amounts of medical data while making it very hard for that data to leak.

One promising approach is now getting its first big test at Stanford Medical School in California. Patients there can choose to contribute their medical data to an AI system that can be trained to diagnose eye disease without ever actually accessing their personal details.

Participants submit ophthalmology test results and health record data through an app. The information is used to train a machine-learning model to identify signs of eye disease in the images. But the data is protected by technology developed by Oasis Labs, a startup spun out of UC Berkeley, which guarantees that the information cannot be leaked or misused. The startup was granted permission by regulators to start the trial last week.

The sensitivity of private patient data is a looming problem. AI algorithms trained on data from different hospitals could potentially diagnose illness, prevent disease, and extend lives. But in many countries medical records cannot easily be shared and fed to these algorithms for legal reasons. Research on using AI to spot disease in medical images or data usually involves relatively small data sets, which greatly limits the technology’s promise….

Oasis stores the private patient data on a secure chip, designed in collaboration with other researchers at Berkeley. The data remains within the Oasis cloud; outsiders are able to run algorithms on the data, and receive the results, without its ever leaving the system. A smart contract—software that runs on top of a blockchain—is triggered when a request to access the data is received. This software logs how the data was used and also checks to make sure the machine-learning computation was carried out correctly….(More)”.

Publics in Emerging Economies Worry Social Media Sow Division, Even as They Offer New Chances for Political Engagement

Curated on Posted on by Stefaan Verhulst

Aaron Smith, Laura Silver, Courtney Johnson, Kyle Taylor and Jingjing Jiang at Pew Research: “In recent years, the internet and social media have been integral to political protests, social movements and election campaigns around the globe. Events from the Arab Spring to the worldwide spread of#MeToo have been aided by digital connectivity in both advanced and emerging economies. But popular social media and messaging platforms like Facebook and WhatsApp have drawn attention for their potential role in spreading misinformation, facilitating political manipulation by foreign and domestic actors, and increasing violence and hate crimes.

Recently, the Sri Lankan government shut down several of the country’s social media and messaging services immediately after Easter day bombings at Catholic churches killed and wounded hundreds. Some technology enthusiasts praised the decision but wondered if this development marked a change from pro-democracy, Arab Spring-era hopes that digital technology would be a liberating tool to a new fear that it has become “a force that can corrode” societies.

In the context of these developments, a Pew Research Center survey of adults in 11 emerging economies finds these publics are worried about the risks associated with social media and other communications technologies – even as they cite their benefits in other respects. Succinctly put, the prevailing view in the surveyed countries is that mobile phones, the internet and social media have collectively amplified politics in both positive and negative directions – simultaneously making people more empowered politically andpotentially more exposed to harm.

Chart showing that people in emerging economies see social media giving them political voice but also increasing the risk of manipulation.

When it comes to the benefits, adults in these countries see digital connectivity enhancing people’s access to political information and facilitating engagement with their domestic politics. Majorities in each country say access to the internet, mobile phones and social media has made people more informed about current events, and majorities in most countries believe social media have increased ordinary people’s ability to have a meaningful voice in the political process. Additionally, half or more in seven of these 11 countries say technology has made people more accepting of those who have different views than they do.

But these perceived benefits are frequently accompanied by concerns about the limitations of technology as a tool for political action or information seeking. Even as many say social media have increased the influence of ordinary people in the political process, majorities in eight of these 11 countries feel these platforms have simultaneously increased the risk that people might be manipulated by domestic politicians. Around half or more in eight countries also think these platforms increase the risk that foreign powers might interfere in their country’s elections….(More)”.

How Cold Is That Library? There’s a Google Doc for That

Curated on Posted on by Stefaan Verhulst

Colleen Flaherty at Inside Higher Ed: “What a difference preparation makes when it comes to doing research in Arctic-level air-conditioned academic libraries (or ones that are otherwise freezing — or not air-conditioned at all). Luckily, Megan L. Cook, assistant professor of English at Colby College, published a crowdsourced document called“How Cold Is that Library?” ….

Cook, who was not immediately available for comment, has said the document was group effort. Juliet Sperling, a faculty fellow in American art at Colby, credited her colleague’s “brilliance” but said the document was “generally inspired by conversations we’ve had as co-fellows” in the Andrew W. Mellon Society of Fellows in Critical Bibliography. The society brings together 60-some scholars of rare books and material texts from a variety of disciplinary or institutional approaches, she said, “so collectively, we’ve all spent quite a bit of time in libraries of various climates all over the world.” In addition to library temperatures, lighting and even humidity levels, the scholars trade research destinations’ photo policies and nearby eateries and drinking holes, among other tips. A spreadsheet opens up that resource to others, Sperling said. …(More)”.

Missing Numbers

Curated on Posted on by Stefaan Verhulst

Introduction by Anna Powell-Smith of a new “blog on the data the government should collect, but doesn’t”: “…Over time, I started to notice a pattern. Across lots of different policy areas, it was impossible for governments to make good decisions because of a basic lack of data. There was always critical data that the state either didn’t collect at all, or collected so badly that it made change impossible.

Eventually, I decided that the power to not collect data is one of the most important and little-understood sources of power that governments have. This is why I’m writing Missing Numbers: to encourage others to ask “is this lack of data a deliberate ploy to get away with something”?

By refusing to amass knowledge in the first place, decision-makers exert power over over the rest of us. It’s time that this power was revealed, so we can have better conversations about what we need to know to run this country successfully.

A typical example

The government records and publishes data on how often each NHS hospital receives formal complaints. This is very helpful, because it means patients and the people who care for them can spot hospitals whose performance is worrying.

But the government simply doesn’t record data, even internally, on how often formal complaints are made about each Jobcentre. (That FOI response is from 2015, but I’ve confirmed it’s still true in 2019.) So it is impossible for it to know if some Jobcentres are being seriously mismanaged….(More)”.
