Citizen scientists aid Ecuador earthquake relief

Curated on Posted on by Stefaan Verhulst

Mark Zastrow at Nature: “After a magnitude-7.8 earthquake struck Ecuador’s Pacific coast on 16 April, a new ally joined the international relief effort: a citizen-science network called Zooniverse.

On 25 April, Zooniverse launched a website that asks volunteers to analyse rapidly-snapped satellite imagery of the disaster, which led to more than 650 reported deaths and 16,000 injuries. The aim is to help relief workers on the ground to find the most heavily damaged regions and identify which roads are passable.

Several crisis-mapping programmes with thousands of volunteers already exist — but it can take days to train satellites on the damaged region and to transmit data to humanitarian organizations, and results have not always proven useful. The Ecuador quake marked the first live public test for an effort dubbed the Planetary Response Network (PRN), which promises to be both more nimble than previous efforts, and to use more rigorous machine-learning algorithms to evaluate the quality of crowd-sourced analyses.

The network relies on imagery from the satellite company Planet Labs in San Francisco, California, which uses an array of shoebox-sized satellites to map the planet. In order to speed up the crowd-sourced process, it uses the Zooniverse platform to distribute the tasks of spotting features in satellite images. Machine-learning algorithms employed by a team at the University of Oxford, UK, then classify the reliability of each volunteer’s analysis and weight their contributions accordingly.

Rapid-fire data

Within 2 hours of the Ecuador test project going live with a first set of 1,300 images, each photo had been checked at least 20 times. “It was one of the fastest responses I’ve seen,” says Brooke Simmons, an astronomer at the University of California, San Diego, who leads the image processing. Steven Reece, who heads the Oxford team’s machine-learning effort, says that results — a “heat map” of damage with possible road blockages — were ready in another two hours.

In all, more than 2,800 Zooniverse users contributed to analysing roughly 25,000 square kilometres of imagery centred around the coastal cities of Pedernales and Bahia de Caraquez. That is where the London-based relief organization Rescue Global — which requested the analysis the day after the earthquake — currently has relief teams on the ground, including search dogs and medical units….(More)”

Open Data Supply: Enriching the usability of information

Curated on Posted on by Stefaan Verhulst

Report by Phoensight: “With the emergence of increasing computational power, high cloud storage capacity and big data comes an eager anticipation of one of the biggest IT transformations of our society today.

Open data has an instrumental role to play in our digital revolution by creating unprecedented opportunities for governments and businesses to leverage off previously unavailable information to strengthen their analytics and decision making for new client experiences. Whilst virtually every business recognises the value of data and the importance of the analytics built on it, the ability to realise the potential for maximising revenue and cost savings is not straightforward. The discovery of valuable insights often involves the acquisition of new data and an understanding of it. As we move towards an increasing supply of open data, technological and other entrepreneurs will look to better utilise government information for improved productivity.

This report uses a data-centric approach to examine the usability of information by considering ways in which open data could better facilitate data-driven innovations and further boost our economy. It assesses the state of open data today and suggests ways in which data providers could supply open data to optimise its use. A number of useful measures of information usability such as accessibility, quantity, quality and openness are presented which together contribute to the Open Data Usability Index (ODUI). For the first time, a comprehensive assessment of open data usability has been developed and is expected to be a critical step in taking the open data agenda to the next level.

With over two million government datasets assessed against the open data usability framework and models developed to link entire country’s datasets to key industry sectors, never before has such an extensive analysis been undertaken. Government open data across Australia, Canada, Singapore, the United Kingdom and the United States reveal that most countries have the capacity for improvements in their information usability. It was found that for 2015 the United Kingdom led the way followed by Canada, Singapore, the United States and Australia. The global potential of government open data is expected to reach 20 exabytes by 2020, provided governments are able to release as much data as possible within legislative constraints….(More)”

How to See Gentrification Coming

Curated on Posted on by Stefaan Verhulst

Nathan Collins at Pacific Standard: “Depending on whom you ask, gentrification is either damaging, not so bad, or maybe even good for the low-income people who live in what we euphemistically call up-and-coming neighborhoods. Either way, it’d be nice for everybody to know which neighborhoods are going to get revitalized/eviscerated next. Now, computer scientists think they’ve found a way to do exactly that: Using Twitter and Foursquare, map the places visited by the most socially diverse crowds. Those, it turns out, are the most likely to gentrify.

Led by University of Cambridge graduate student Desislava Hristova, the researchers began their study by mapping out the social network of 37,722 Londoners who posted Foursquare check-ins via Twitter. Two people were presumed to be friends—connected on the social network—if they followed each other’s Twitter feeds. Next, Hristova and her colleagues built a geographical network of 42,080 restaurants, clubs, shops, apartments, and so on. Quaint though it may seem, the researchers treated two places as neighbors in the geographical network if they were, in fact, physically near each other. The team then linked the social and geographical networks using 549,797 Foursquare check-ins, each of which ties a person in the social network to a place in the geographical one.

Gentrification doesn’t start when outsiders move in; it starts when outsiders come to visit.

Using the network data, the team next constructed several measures of the social diversity of places, each of which helps distinguish between places that bring together friends versus strangers, and to distinguish between spots that attract socially diverse crowds versus a steady group of regulars. Among other things, those measures showed that places in the outer boroughs of London brought together more socially homogenous groups of people—in terms of their Foursquare check-ins, at least—compared with boroughs closer to the core.

But the real question is what social diversity has to do with gentrification. To measure that, the team used the United Kingdom’s Index of Multiple Deprivation, which takes into account income, education, environmental factors such as air quality, and more to quantify the socioeconomic state of affairs in localities across the U.K., including each of London’s 32 boroughs.

The rough pattern, according to the analysis: The most socially diverse places in London were also the most deprived. This is about the opposite of what you’d expect, based on social networks studied in isolation from geography, which indicates that, generally, the people with the most diverse social networks are the most prosperous….(More)”

Social app for refugees and locals translates in real-time

Curated on Posted on by Stefaan Verhulst

Springwise: “Europe is in the middle of a major refugee crisis, with more than one million migrants arriving in 2015 alone. Now, developers in Stockholm are coming up with new ways for arrivals to integrate into their new homes.

Welcome! is an app based in Sweden, a country that has operated a broadly open policy to immigration in recent years. The developers say the app aims to break down social and language barriers between Swedes and refugees. Welcome! is translated into Arabic, Persian, Swedish and English, and it enables users to create, host and join activities, as well as ask questions of locals, chat with new contacts, and browse events that are nearby.

The idea is to solve one of the major difficulties for immigrants arriving in Europe by encouraging the new arrivals and locals to interact and connect, helping the refugees to settle in. The app offers real-time auto-translation through its four languages, and can be downloaded for iOS and Android….We have already seen an initiative in Finland helping to set up startups with refugees…(More)“

Pigeon patrol takes flight to tackle London’s air pollution crisis

Curated on Posted on by Stefaan Verhulst

 at The Guardian: They’ve been driven from Trafalgar square for being a nuisance, derided as rats with wings and maligned as a risk to public health.

But now pigeons could play a small part in helping Londoners overcome one of the capital’s biggest health problems – its illegal levels of air pollution blamed for thousands of deaths a year.

On Monday, a flock of half a dozen racing pigeons were set loose from a rooftop in Brick Lane by pigeon fancier, Brian Woodhouse, with one strapped with a pollution sensor to its back and one with a GPS tracker.

But while the 25g sensor records the nitrogen dioxide produced by the city’s diesel cars, buses, and trucks and tweets it at anyone who asks for a reading, its real purpose – and the use of the pigeons – is to raise awareness.

“It is a scandal. It is a health and environmental scandal for humans – and pigeons. We’re making the invisible visible,” said Pierre Duquesnoy, who won a London Design Festival award for the idea last year.

“Most of the time when we talk about pollution people think about Beijing or other places, but there are some days in the year when pollution was higher and more toxic in London than Beijing, that’s the reality.”

He said he was inspired by the use of pigeons in the first and second world wars to deliver information and save lives, but they were also a practical way of taking mobile air quality readings and beating London’s congested roads. They fly relatively low, at 100-150ft, and fast, at speeds up to 80mph.

“There’s something about taking what is seen as a flying rat and reversing that into something quite positive,” said Duquesnoy, who is creative director at marketing agency DigitasLBI.

Gary Fuller, an air quality expert at King’s College London, said it was the first time he had heard of urban animals being put to such use.

“It’s great that unemployed pigeons from Trafalgar Square are being put to work. Around 15 years ago tests were done on around 150 stray dogs in Mexico City, showing the ways in which air pollution was affecting lungs and heart health. But this is the first time that I’ve heard of urban wild animals being used to carry sensors to give us a picture of the air pollution over our heads.”

The release of the pigeons for three days this week, dubbed the Pigeon Air Patrol, came as moderate to high pollution affected much of the city, with Battersea recording ‘very high’, the top of the scale.

Elsewhere in the UK, Stockton-on-tees and Middlesbrough recorded high pollution readings and the forecast is for moderate and possibly high pollution in urban areas in northern England and Scotland on Tuesday. Other areas will have low pollution levels….(More).

Cities, Data, and Digital Innovation

Curated on Posted on by Stefaan Verhulst

Paper by Mark Kleinman: “Developments in digital innovation and the availability of large-scale data sets create opportunities for new economic activities and new ways of delivering city services while raising concerns about privacy. This paper defines the terms Big Data, Open Data, Open Government, and Smart Cities and uses two case studies – London (U.K.) and Toronto – to examine questions about using data to drive economic growth, improve the accountability of government to citizens, and offer more digitally enabled services. The paper notes that London has been one of a handful of cities at the forefront of the Open Data movement and has been successful in developing its high-tech sector, although it has so far been less innovative in the use of “smart city” technology to improve services and lower costs. Toronto has also made efforts to harness data, although it is behind London in promoting Open Data. Moreover, although Toronto has many assets that could contribute to innovation and economic growth, including a growing high-technology sector, world-class universities and research base, and its role as a leading financial centre, it lacks a clear narrative about how these assets could be used to promote the city. The paper draws some general conclusions about the links between data innovation and economic growth, and between open data and open government, as well as ways to use big data and technological innovation to ensure greater efficiency in the provision of city services…(More)“

The 4 Types of Cities and How to Prepare Them for the Future

Curated on Posted on by Stefaan Verhulst

John D. Macomber at Harvard Business Review: “The prospect of urban innovation excites the imagination. But dreaming up what a “smart city” will look like in some gleaming future is, by its nature, a utopian exercise. The messy truth is that cities are not the same, and even the most innovative approach can never achieve universal impact. What’s appealing for intellectuals in Copenhagen or Amsterdam is unlikely to help millions of workers in Jakarta or Lagos. To really make a difference, private entrepreneurs and civic entrepreneurs need to match projects to specific circumstances. An effective starting point is to break cities into four segments across two distinctions: legacy vs. new cities, and developed vs. emerging economies. The opportunities to innovate will differ greatly by segment.

Segment 1: Developed Economy, Legacy City
Examples: London, Detroit, Tokyo, Singapore

Characteristics: Any intervention in a legacy city has to dismantle something that existed before — a road or building, or even a regulatory authority or an entrenched service business. Slow demographic growth in developed economies creates a zero-sum situation (which is part of why the licensed cabs vs Uber/Lyft contest is so heated). Elites live in these cities, so solutions arise that primarily help users spend their excess cash. Yelp, Zillow, and Trip Advisor are examples of innovations in this context.
Implications for city leaders: Leaders should try to establish a setting where entrepreneurs can create solutions that improve quality of life — without added government expense. …

Implications for entrepreneurs: Denizens of developed legacy cities have discretionary income. …

Segment 2: Emerging Economy, Legacy City
Examples: Mumbai, São Paolo, Jakarta

Characteristics: Most physical and institutional structures are already in place in these megacities, but with fast-growing populations and severe congestion, there is an opportunity to create value by improving efficiency and livability, and there is a market of customers with cash to pay for these benefits.

Implications for city leaders: Leaders should loosen restrictions so that private finance can invest in improvements to physical infrastructure, to better use what already exists. …

Implications for entrepreneurs: Focus on public-private partnerships (PPP). …

Segment 3: Emerging Economy, New City
Examples: Phu My Hung, Vietnam; Suzhou, China; Astana, Kazakhstan; Singapore (historically)

Characteristics: These cities tend to have high population growth and high growth rates in GDP per capita, demographic and economic tailwinds that help to boost returns. The urban areas have few existing physical or social structures to dismantle as they grow, hence fewer entrenched obstacles to new offerings. There is also immediate ROI for investments in basic services as population moves in, because they capture new revenues from new users. Finally, in these cities there is an important chance to build it right the first time, notably with respect to the roads, bridges, water, and power that will determine both economic competitiveness and quality of life for decades. The downside? If this chance is missed, new urban agglomerations will be characterized by informal sprawl and new settlements will be hard to reach after the fact with power, roads, and sanitation.
Implications for city leaders: Leaders should first focus on building hard infrastructure that will support services such as schools, hospitals, and parks. …

Implications for entrepreneurs: In these cities, it’s too soon to think about optimizing existing infrastructure or establishing amusing ways for wealthy people to spend their disposable income. …

Segment 4: Developed Economy, New City
Examples and characteristics: Such cities are very rare. All the moment, almost all self-proclaimed “new cities” in the developed world are in fact large, integrated real-estate developments with an urban theme, usually in close proximity to a true municipality. Examples of these initiatives include New Songdo City in South Korea, Masdar City in Abu Dhabi, and Hafen City Hamburg in Germany.

Implications for city leaders: These satellites of existing metropolises compete for jobs and to attract talented participants in the creative economy. ….

Implications for entrepreneurs: Align with city leaders on services that are important to knowledge workers, and help build the cities’ brand. ….

Cities are different. So are solutions….(More)

Letting the people decide … but will government listen?

Curated on Posted on by Stefaan Verhulst

 in The Mandarin: “If we now have the technology to allow citizens to vote directly on all issues, what job remains for public servants?

While new technology may provide new options to contribute, the really important thing is governmental willingness to actually listen, says Maria Katsonis, the Victorian Department of Premier and Cabinet’s director of equality.

The balance between citizen consultation and public service expertise in decision-making remains a hot debate, with South Australian Premier Jay Weatherill warning last year that while expertise in policy is important, overzealous bureaucrats and politicians can disenfranchise citizens.

The internet is assisting government to attain opinions from people more easily than ever before. SA, for example, has embraced the use of citizen juries in policy formation through its youSAy portal — though as yet on only some issues. Finland has experimented with digitally crowdsourcing input into the policymaking process.

The Victorian government, meanwhile, has received blowback around claims its recent announcement for a “skyrail” in Melbourne’s south-eastern suburbs went ahead with very little consultation…

Indeed, even a direct vote doesn’t mean the government is really listening to the people. A notable example of a government using a poorly designed popular vote to rubber stamp its own intentions was an online poll in Queensland on whether to cut public transport fares which was worded to suit the government’s own predilections.

Giving citizens the tools to contribute

Katsonis said she didn’t want to “diss crowdsourcing”; governments should think about where using it might be appropriate, and where it might not. Directly crowdsourcing legislation is perhaps not the best way to use the “wisdom of the crowd”, she suggested….The use of people’s panels to inform policy and budgeting — for example at the City of Melbourne — shows some promise as one tool to improve engagement. Participants of people’s panels — which see groups of ordinary citizens being given background information about the task at hand and then asked to come up with a proposal for what to do — tend to report a higher trust in governmental processes after they’ve gained some experience of the difficulty of making those decisions.

One of the benefits of that system is the chance to give participants the tools to understand those processes for themselves, rather than going in cold, as some other direct participation tools do….

Despite the risks, processes such as citizens’ panels are still a more nuanced approach than calls for frequent referenda or the new breed of internet-based political parties, such as Australia’s Online Direct Democracy, that promise their members of parliament will vote however a majority of voters tell them to….(More)”

Open data and (15 million!) new measures of democracy

Curated on Posted on by Stefaan Verhulst

Joshua Tucker in the Washington Post: “Last month the University of Gothenberg’s V-Dem Institute released a new“Varieties of Democracy” dataset. It provides about 15 million data points on democracy, including 39 democracy-related indices. It can be accessed at v-dem.net along with supporting documentation. I asked Staffan I. Lindberg, Director of the V-Dem Institute and one of the directors of the project, a few questions about the new data. What follows is a lightly edited version of his answers.


Women’s Political Empowerment Index for Southeast Asia (Data: V-Dem data version 5; Figure V-Dem Institute, University of Gothenberg, Sweden)

Joshua Tucker: What is democracy, and is it even really to have quantitative measures on democracy?

Staffan Lindberg: There is no consensus on the definition of democracy and how to measure it. The understanding of what a democracy really is varies across countries and regions. This motivates the V-Dem approach not to offer one standard definition of the concept but instead to distinguish among five principles different versions of democracy: Electoral, Liberal, Participatory, Deliberative, and Egalitarian democracy. All of these principles have played prominent roles in current and historical discussions about democracy. Our measurement of these principles are based on two types of data, factual data collected by assisting researchers and survey responses by country experts, which are combined using a rather complex measurement model (which is a“custom-designed Bayesian ordinal item response theory model”, for details see the V-Dem Methodology document)….(More)

Big data’s big role in humanitarian aid

Curated on Posted on by Stefaan Verhulst

Mary K. Pratt at Computerworld: “Hundreds of thousands of refugees streamed into Europe in 2015 from Syria and other Middle Eastern countries. Some estimates put the number at nearly a million.

The sheer volume of people overwhelmed European officials, who not only had to handle the volatile politics stemming from the crisis, but also had to find food, shelter and other necessities for the migrants.

Sweden, like many of its European Union counterparts, was taking in refugees. The Swedish Migration Board, which usually sees 2,500 asylum seekers in an average month, was accepting 10,000 per week.

“As you can imagine, with that number, it requires a lot of buses, food, registration capabilities to start processing all the cases and to accommodate all of those people,” says Andres Delgado, head of operational control, coordination and analysis at the Swedish Migration Board.

Despite the dramatic spike in refugees coming into the country, the migration agency managed the intake — hiring extra staff, starting the process of procuring housing early, getting supplies ready. Delgado credits a good part of that success to his agency’s use of big data and analytics that let him predict, with a high degree of accuracy, what was heading his way.

“Without having that capability, or looking at the tool every day, to assess every need, this would have crushed us. We wouldn’t have survived this,” Delgado says. “It would have been chaos, actually — nothing short of that.”

The Swedish Migration Board has been using big data and analytics for several years, as it seeks to gain visibility into immigration trends and what those trends will mean for the country…./…

“Can big data give us peace? I think the short answer is we’re starting to explore that. We’re at the very early stages, where there are shining examples of little things here and there. But we’re on that road,” says Kalev H. Leetaru, creator of the GDELT Project, or the Global Database of Events, Language and Tone, which describes itself as a comprehensive “database of human society.”

The topic is gaining traction. A 2013 report, “New Technology and the Prevention of Violence and Conflict,” from the International Peace Institute, highlights uses of telecommunications technology, including data, in several crisis situations around the world. The report emphasizes the potential these technologies hold in helping to ease tensions and address problems.

The report’s conclusion offers this idea: “Big data can be used to identify patterns and signatures associated with conflict — and those associated with peace — presenting huge opportunities for better-informed efforts to prevent violence and conflict.”

That’s welcome news to Noel Dickover. He’s the director of PeaceTech Data Networks at the PeaceTech Lab, which was created by the U.S. Institute of Peace (USIP) to advance USIP’s work on how technology, media and data help reduce violent conflict around the world.

Such work is still in the nascent stages, Dickover says, but people are excited about its potential. “We have unprecedented amounts of data on human sentiment, and we know there’s value there,” he says. “The question is how to connect it.”

Dickover is working on ways to do just that. One example is the Open Situation Room Exchange (OSRx) project, which aims to “empower greater collective impact in preventing or mitigating serious violent conflicts in particular arenas through collaboration and data-sharing.”…(More)
