Science to the people!

Curated on Posted on by Stefaan Verhulst

John Magan, at Digital Agenda for Europe:” …I attended the 2nd Barcelona Citizen Science Day organised as part of the city’s Science Festival. The programme was full and varied and in itself a great example of the wonderful world of do-it-yourself, hands-on, accessible, practical science. A huge variety of projects (see below) was delivered with enthusiasm, passion, and energy!

The day was rounded off with a presentation by Public Lab who showed how a bit of technical ingenuity like cheap cameras on kites and balloons can be used to keep governments and large businesses more honest and accountable – for example, data they collected is being used in court cases against BP for the Deepwater Horizon oil spill in the Gulf of Mexico.

But what was most striking is the empowerment that these Citizen Science projects give individuals to do things for themselves – to take measures to monitor, protect or improve their urban or rural environment; to indulge their curiosity or passions; to improve their finances; to work with others; to do good while having serious fun….If you want to have a deeper look, here are some of the many projects presented on a great variety of themes:

Wildlife

Climate

Arts

Public health

Human

How a Mexico City Traffic Experiment Connects to Community Trust

Curated on Posted on by Stefaan Verhulst

Zoe Mendelson in Next Cities: “Last November, Gómez-Mont, Jose Castillo, an urban planning professor at Harvard’s Graduate School of Design, and Carlos Gershenson, their data analyst, won the Audi Urban Future award for their plan to use big data to solve Mexico City’s traffic problem. The plan consists of three parts, the first a data-donating platform that collects information on origin and destination, transit times, and modes of transit. The app, Living Mobs, is now in use in beta form. The plan also establishes data-sharing partnerships with companies, educational institutions and government agencies. So far, they’ve already signed on Yaxi, Microsoft, Movistar and Uber among others, and collected 14,000 datasets.

The data will be a welcome new resource for the city. “We just don’t have enough,” explains Gómez-Mont, “we call it ‘big city, little data.” The city’s last origin-destination survey conducted in 2007 only caught data from 50,000 people, which at the time was somewhat of a feat. Now, just one of their current data-sharing partners, Yaxi, has 10,000 cars circulating alone. Still, they have one major obstacle to a comprehensive citywide survey that can only be partially addressed by their data-donating platform (which also, of course, does depend on people having smartphones): 60 percent of transportation in Mexico City is on a hard-to-track informal bus system.

The data will eventually end up in an app that gives people real-time transit information. But an underlying idea — that traffic can be solved simply by asking people to take turns — is the project’s most radical and interesting component. Gómez-Mont paints a seductive alternative futuristic vision of incentivized negotiation of the city.

“Say I wake up and while getting ready for work I check and see that Périferico is packed and I say, ‘OK, today I’m going to use my bike or take public transit,’ and maybe I earn some kind of City Points, which translates into a tax break. Or maybe I’m on Périferico and earn points for getting off to relieve congestion.” She even envisions a system through which people could submit their calendar data weeks in advance. With the increasing popularity of Google Calendar and other similar systems that sync with smartphones, advanced “data donation” doesn’t seem that far-fetched.

Essentially, the app would create the opportunity for an entire city to behave as a group and solve its own problems together in real time.

Gómez-Mont insists that mobility is not just a problem for the government to solve. “It’s also very much about citizens and how we behave and what type of culture is embedded in the world outside of the government,” she notes….(More)”.

African American family records from era of slavery to be available free online

Curated on Posted on by Stefaan Verhulst

Joanna Walters in The Guardian: “Millions of African Americans will soon be able to trace their families through the era of slavery, some to the countries from which their ancestors were snatched, thanks to a new and free online service that is digitizing a huge cache of federal records for the first time.

Handwritten records collecting information on newly freed slaves that were compiled just after the civil war will be available for easy searches through a new website, it was announced on Friday.

The records belong to the Freedmen’s Bureau, an administrative body created by Congress in 1865 to assist slaves in 15 states and the District of Columbia transition into free citizenship.

Before that time, slaves were legally regarded as property in the US and their names were not officially documented. They often appeared only as dash marks – even on their owners’ records.

African Americans trying to trace family history today regularly hit the research equivalent of a brick wall prior to 1870, when black people were included in the US census for the first time.

Now a major project run by several organisations is beginning to digitise the 1.5 million handwritten records from the Freedmen’s Bureau, which feature more than four million names and are held by various federal bodies, for full online access.

All the records are expected to be online by late 2016, to coincide with the opening of the new Smithsonian National Museum of African American History and Culture on the National Mall in Washington.

Hollis Gentry, a genealogy specialist at the Smithsonian, said at the announcement of the project in Los Angeles on Friday: “The records serve as a bridge to slavery and freedom. You can look at some of the original documents that were created at the time when these people were living. They are the earliest records detailing people who were formerly enslaved. We get a sense of their voice, their dreams.”…

The Freedmen’s Bureau made records that include marriages and church and financial details as well as full names, dates of birth and histories of slave ownership.

They have been available for access by the public in Washington, but only in person by searching through hundreds of pages of handwritten documents.

The project to put the documents online is a collaboration involving the Smithsonian, the National Archives, the Afro-American Historical and Genealogical Society, the California African American Museum and FamilySearch. The last-named body is a large online genealogy organisation run by the Church of Jesus Christ of Latter-Day Saints – otherwise known as the Mormon church, based in Salt Lake City.

Volunteers will help to digitise the handwritten records and they will be added to the website as they become available. The website is discoverfreedmen.org….”

 

Researcher uncovers inherent biases of big data collected from social media sites

Curated on Posted on by Stefaan Verhulst

Phys.org: “With every click, Facebook, Twitter and other social media users leave behind digital traces of themselves, information that can be used by businesses, government agencies and other groups that rely on “big data.”

But while the information derived from social network sites can shed light on social behavioral traits, some analyses based on this type of data collection are prone to bias from the get-go, according to new research by Northwestern University professor Eszter Hargittai, who heads the Web Use Project.

Since people don’t randomly join Facebook, Twitter or LinkedIn—they deliberately choose to engage —the data are potentially biased in terms of demographics, socioeconomic background or Internet skills, according to the research. This has implications for businesses, municipalities and other groups who use because it excludes certain segments of the population and could lead to unwarranted or faulty conclusions, Hargittai said.

The study, “Is Bigger Always Better? Potential Biases of Big Data Derived from Social Network Sites” was published last month in the journal The Annals of the American Academy of Political and Social Science and is part of a larger, ongoing study.

The buzzword “big data” refers to automatically generated information about people’s behavior. It’s called “big” because it can easily include millions of observations if not more. In contrast to surveys, which require explicit responses to questions, big data is created when people do things using a service or system.

“The problem is that the only people whose behaviors and opinions are represented are those who decided to join the site in the first place,” said Hargittai, the April McClain-Delaney and John Delaney Professor in the School of Communication. “If people are analyzing big data to answer certain questions, they may be leaving out entire groups of people and their voices.”

For example, a city could use Twitter to collect local opinion regarding how to make the community more “age-friendly” or whether more bike lanes are needed. In those cases, “it’s really important to know that people aren’t on Twitter randomly, and you would only get a certain type of person’s response to the question,” said Hargittai.

“You could be missing half the population, if not more. The same holds true for companies who only use Twitter and Facebook and are looking for feedback about their products,” she said. “It really has implications for every kind of group.”…

Rethinking Smart Cities From The Ground Up

Curated on Posted on by Stefaan Verhulst

New report byTom Saunders and Peter Baeck (NESTA): “This report tells the stories of cities around the world – from Beijing to Amsterdam, and from London to Jakarta – that are addressing urban challenges by using digital technologies to engage and enable citizens.

Key findings

  • Many ‘top down’ smart city ideas have failed to deliver on their promise, combining high costs and low returns.
  • ‘Collaborative technologies’ offer cities another way to make smarter use of resources, smarter ways of collecting data and smarter ways to make decisions.
  • Collaborative technologies can also help citizens themselves shape the future of their cities.
  • We have created five recommendations for city government who want to make their cities smarter.

As cities bring people together to live, work and play, they amplify their ability to create wealth and ideas. But scale and density also bring acute challenges: how to move around people and things; how to provide energy; how to keep people safe.

‘Smart cities’ offer sensors, ‘big data’ and advanced computing as answers to these challenges, but they have often faced criticism for being too concerned with hardware rather than with people.

In this report we argue that successful smart cities of the future will combine the best aspects of technology infrastructure while making the most of the growing potential of ‘collaborative technologies’, technologies that enable greater collaboration between urban communities and between citizens and city governments.

How will this work in practice? Drawing on examples from all around the world we investigate four emerging methods which are helping city governments engage and enable citizens: the collaborative economy, crowdsourcing data, collective intelligence and crowdfunding.

Policy recommendations

  1. Set up a civic innovation lab to drive innovation in collaborative technologies.
  2. Use open data and open platforms to mobilise collective knowledge.
  3. Take human behaviour as seriously as technology.
  4. Invest in smart people, not just smart technology.
  5. Spread the potential of collaborative technologies to all parts of society….(More)”

This App Lets You See The Tough Choices Needed To Balance Your City’s Budget

Curated on Posted on by Stefaan Verhulst

Jay Cassano at FastCoExist: “Ask the average person on the street how much money their city spends on education or health care or police. Even the most well-informed probably won’t be able to come up with a dollar amount. That’s because even if you are interested, municipal budgets aren’t presented in a way that makes sense to ordinary people.

Balancing Act is a web app that displays a straightforward pie chart of a city’s budget, broken down into categories like pensions, parks & recreations, police, and education. But it doesn’t just display the current budget breakdown. It invites users to tweak it, expressing their own priorities, all while keeping the city in the black. Do you want your libraries to be better funded? Fine—but you’re going to have to raise property taxes to do it.

“Balancing Act provides a way for people to both understand what public entities are doing and then to weight that against the other possible things that government can do,” says Chris Adams, president of Engaged Public, a Colorado-based consulting firm that develops technology for government and non-profits. “Especially in this era of information, all of us have a responsibility to spend a bit of time understanding how our government is spending money on our behalf.”

Hartford, Connecticut is the first city in the country that is using Balancing Act. The city was facing a $49 million budget deficit this spring, and Mayor Pedro Segarra says he took input from citizens using Balancing Act. Meanwhile, in Engaged Public’s home state, residents can input their income to generate an itemized tax receipt and then tweak the Colorado state budget as they see fit.

Engaged Public hopes that by making budgets more interactive and accessible, more people will take an interest in them.

“Budget information almost universally exists, but it’s not in accessible formats—mostly they’re in PDF files,” says Adams. “So citizens are invited to pour through tens of thousands of pages of PDFs. But that really doesn’t give you a high-level understanding of what’s at stake in a reasonable amount of time.”

If widely used, Balancing Act could be a useful tool for politicians to check the pulse of their constituents. For example, decreasing funding to parks draws a negative public reaction. But if enough people on Balancing Act experimented with the budget, saw the necessity of it, and submitted their recommendations, then an elected might be willing to make a decision that would otherwise seem politically risky….(More)”

Big Data’s Impact on Public Transportation

Curated on Posted on by Stefaan Verhulst

InnovationEnterprise: “Getting around any big city can be a real pain. Traffic jams seem to be a constant complaint, and simply getting to work can turn into a chore, even on the best of days. With more people than ever before flocking to the world’s major metropolitan areas, the issues of crowding and inefficient transportation only stand to get much worse. Luckily, the traditional methods of managing public transportation could be on the verge of changing thanks to advances in big data. While big data use cases have been a part of the business world for years now, city planners and transportation experts are quickly realizing how valuable it can be when making improvements to city transportation. That hour long commute may no longer be something travelers will have to worry about in the future.

In much the same way that big data has transformed businesses around the world by offering greater insight in the behavior of their customers, it can also provide a deeper look at travellers. Like retail customers, commuters have certain patterns they like to keep to when on the road or riding the rails. Travellers also have their own motivations and desires, and getting to the heart of their actions is all part of what big data analytics is about. By analyzing these actions and the factors that go into them, transportation experts can gain a better understanding of why people choose certain routes or why they prefer one method of transportation over another. Based on these findings, planners can then figure out where to focus their efforts and respond to the needs of millions of commuters.

Gathering the accurate data needed to make knowledgeable decisions regarding city transportation can be a challenge in itself, especially considering how many people commute to work in a major city. New methods of data collection have made that effort easier and a lot less costly. One way that’s been implemented is through the gathering of call data records (CDR). From regular transactions made from mobile devices, information about location, time, and duration of an action (like a phone call) can give data scientists the necessary details on where people are traveling to, how long it takes them to get to their destination, and other useful statistics. The valuable part of this data is the sample size, which provides a much bigger picture of the transportation patterns of travellers.

That’s not the only way cities are using big data to improve public transportation though. Melbourne in Australia has long been considered one of the world’s best cities for public transit, and much of that is thanks to big data. With big data and ad hoc analysis, Melbourne’s acclaimed tram system can automatically reconfigure routes in response to sudden problems or challenges, such as a major city event or natural disaster. Data is also used in this system to fix problems before they turn serious.Sensors located in equipment like tram cars and tracks can detect when maintenance is needed on a specific part. Crews are quickly dispatched to repair what needs fixing, and the tram system continues to run smoothly. This is similar to the idea of the Internet of Things, wherein embedded sensors collect data that is then analyzed to identify problems and improve efficiency.

Sao Paulo, Brazil is another city that sees the value of using big data for its public transportation. The city’s efforts concentrate on improving the management of its bus fleet. With big data collected in real time, the city can get a more accurate picture of just how many people are riding the buses, which routes are on time, how drivers respond to changing conditions, and many other factors. Based off of this information, Sao Paulo can optimize its operations, providing added vehicles where demand is genuine whilst finding which routes are the most efficient. Without big data analytics, this process would have taken a very long time and would likely be hit-or-miss in terms of accuracy, but now, big data provides more certainty in a shorter amount of time….(More)”

Exploring Open Energy Data in Urban Areas

Curated on Posted on by Stefaan Verhulst

The Worldbank: “…Energy efficiency – using less energy input to deliver the same level of service – has been described by many as the ‘first fuel’ of our societies. However, lack of adequate data to accurately predict and measure energy efficiency savings, particularly at the city level, has limited the realization of its promise over the past two decades.
Why Open Energy Data?
Open Data can be a powerful tool to reduce information asymmetry in markets, increase transparency and help achieve local economic development goals. Several sectors like transport, public sector management and agriculture have started to benefit from Open Data practices. Energy markets are often characterized by less-than-optimal conditions with high system inefficiencies, misaligned incentives and low levels of transparency. As such, the sector has a lot to potentially gain from embracing Open Data principles.
The United States is a leader in this field with its ‘Energy Data’ initiative. This initiative makes data easy to find, understand and apply, helping to fuel a clean energy economy. For example, the Energy Information Administration’s (EIA) open application programming interface (API) has more than 1.2 million time series of data and is frequently visited by users from the private sector, civil society and media. In addition, the Green Button  initiative is empowering American citizens to have access to their own energy usage data, and OpenEI.org is an Open Energy Information platform to help people find energy information, share their knowledge and connect to other energy stakeholders.
Introducing the Open Energy Data Assessment
To address this data gap in emerging and developing countries, the World Bank is conducting a series of Open Energy Data Assessments in urban areas. The objective is to identify important energy-related data, raise awareness of the benefits of Open Data principles and improve the flow of data between traditional energy stakeholders and others interested in the sector.
The first cities we assessed were Accra, Ghana and Nairobi, Kenya. Both are among the fastest-growing cities in the world, with dynamic entrepreneurial and technology sectors, and both are capitals of countries with an ongoing National Open Data Initiative., The two cities have also been selected to be part of the Negawatt Challenge, a World Bank international competition supporting technology innovation to solve local energy challenges.
The ecosystem approach
The starting point for the exercise was to consider the urban energy sector as an ecosystem, comprised of data suppliers, data users, key datasets, a legal framework, funding mechanisms, and ICT infrastructure. The methodology that we used adapted the established World Bank Open Data Readiness Assessment (ODRA), which highlights valuable connections between data suppliers and data demand.  The assessment showcases how to match pressing urban challenges with the opportunity to release and use data to address them, creating a longer-term commitment to the process. Mobilizing key stakeholders to provide quick, tangible results is also key to this approach….(More) …See also World Bank Open Government Data Toolkit.”

Waze and the Traffic Panopticon

Curated on Posted on by Stefaan Verhulst

 in the New Yorker: “In April, during his second annual State of the City address, Los Angeles Mayor Eric Garcetti announced a data-sharing agreement with Waze, the Google-owned, Israel-based navigation service. Waze is different from most navigation apps, including Google Maps, in that it relies heavily on real-time, user-generated data. Some of this data is produced actively—a driver or passenger sees a stalled vehicle, then uses a voice command or taps a stalled-vehicle icon on the app to alert others—while other data, such as the user’s location and average speed, is gathered passively, via smartphones. The agreement will see the city provide Waze with some of the active data it collects, alerting drivers to road closures, construction, and parades, among other things. From Waze, the city will get real-time data on traffic and road conditions. Garcetti said that the partnership would mean “less congestion, better routing, and a more livable L.A.” Di-Ann Eisnor, Waze’s head of growth, acknowledged to me that these kinds of deals can cause discomfort to the people working inside city government. “It’s exciting, but people inside are also fearful because it seems like too much work, or it seems so unknown,” she said.

Indeed, the deal promises to help the city improve some of its traffic and infrastructure systems (L.A. still uses paper to manage pothole patching, for example), but it also acknowledges Waze’s role in the complex new reality of urban traffic planning. Traditionally, traffic management has been a largely top-down process. In Los Angeles, it is coördinated in a bunker downtown, several stories below the sidewalk, where engineers stare at blinking lights representing traffic and live camera feeds of street intersections. L.A.’s sensor-and-algorithm-driven Automated Traffic Surveillance and Control System is already one of the world’s most sophisticated traffic-mitigation tools, but it can only do so much to manage the city’s eternally unsophisticated gridlock. Los Angeles appears to see its partnership with Waze as an important step toward improving the bridge between its subterranean panopticon and the rest of the city still further, much like other metropolises that have struck deals with Waze under the company’s Connected Cities program.
Among the early adopters is Rio de Janeiro, whose urban command center tracks everything from accidents to hyperlocal weather conditions, pulling data from thirty departments and private companies, including Waze. “In Rio,” Eisnor said, traffic managers “were able to change the garbage routes, figure out where to install cameras, and deploy traffic personnel” because of the program. She also pointed out that Connected Cities has helped municipal workers in Washington, D.C., patch potholes within forty-eight hours of their being identified on Waze. “We’re helping reframe city planning through not just space but space and time,” she said…..(More)“

Citizen-Driven Innovation : A Guidebook for City Mayors and Public Administrators

Curated on Posted on by Stefaan Verhulst

Guidebook by Eskelinen, Jarmo; Garcia Robles, Ana; Lindy, Ilari; Marsh, Jesse; Muente-Kunigami, Arturo:  “… aims to bring citizen-driven innovation to policy makers and change agents around the globe, by spreading good practice on open and participatory approaches as applied to digital service development in different nations, climates, cultures, and urban settings. The report explores the concept of smart cities through a lens that promotes citizens as the driving force of urban innovation. Different models of smart cities are presented, showing how citizen-centric methods have been used to mobilize resources to respond to urban innovation challenges in a variety of situations, objectives, and governance structures. The living lab approach strengthens these processes as one of the leading methods for agile development or the rapid prototyping of ideas, concepts, products, services, and processes in a highly decentralized and user-centric manner. By adopting these approaches and promoting citizen-driven innovation, cities around the world are aiming to alleviate the demand for services, increase the quality of delivery, and promote local entrepreneurship. This guidebook is structured into seven main sections: an introductory section describes the vision of a humanly smart city, in order to give an idea of the kind of result that can be attained from opening up and applying citizen-driven innovation methods. Chapter one getting started helps mayors launch co-design initiatives, exploring innovation processes founded on trust and verifying the benefits of opening up. Chapter two, building a strategy identifies the key steps for building an innovation partnership and together defining a sustainable city vision and scenarios for getting there. Chapter three, co-designing solutions looks at the process of unpacking concrete problems, working creatively to address them, and following up on implementation. Chapter four, ensuring sustainability describes key elements for long-term viability: evaluation and impact assessment, appropriate institutional structuring, and funding and policy support. Chapter five, joining forces suggests ways to identify a unique role for participation in international networks and how to best learn from cooperation. Finally, the report provides a starter pack with some of the more commonly used tools and methods to support the kinds of activities described in this guidebook….(More)”
