NIH-funded team uses smartphone data in global study of physical activity

Curated on Posted on by Stefaan Verhulst

National Institutes of Health: “Using a larger dataset than for any previous human movement study, National Institutes of Health-funded researchers at Stanford University in Palo Alto, California, have tracked physical activity by population for more than 100 countries. Their research follows on a recent estimate that more than 5 million people die each year from causes associated with inactivity.

The large-scale study of daily step data from anonymous smartphone users dials in on how countries, genders, and community types fare in terms of physical activity and what results may mean for intervention efforts around physical activity and obesity. The study was published July 10, 2017, in the advance online edition of Nature.

“Big data is not just about big numbers, but also the patterns that can explain important health trends,” said Grace Peng, Ph.D., director of the National Institute of Biomedical Imaging and Bioengineering (NIBIB) program in Computational Modeling, Simulation and Analysis.

“Data science and modeling can be immensely powerful tools. They can aid in harnessing and analyzing all the personalized data that we get from our phones and wearable devices.”

Almost three quarters of adults in developed countries and half of adults in developing economies carry a smartphone. The devices are equipped with tiny accelerometers, computer chip that maintains the orientation of the screen, and can also automatically record stepping motions. The users whose data contributed to this study subscribed to the Azumio Argus app, a free application for tracking physical activity and other health behaviors….

In addition to the step records, the researchers accessed age, gender, and height and weight status of users who registered the smartphone app. They used the same calculation that economists use for income inequality — called the Gini index — to calculate activity inequality by country.

“These results reveal how much of a population is activity-rich, and how much of a population is activity-poor,” Delp said. “In regions with high activity inequality there are many people who are activity poor, and activity inequality is a strong predictor of health outcomes.”…

The researchers investigated the idea that making improvements in a city’s walkability — creating an environment that is safe and enjoyable to walk — could reduce activity inequality and the activity gender gap.

“If you must cross major highways to get from point A to point B in a city, the walkability is low; people rely on cars,” Delp said. “In cities like New York and San Francisco, where you can get across town on foot safely, the city has high walkability.”

Data from 69 U.S. cities showed that higher walkability scores are associated with lower activity inequality. Higher walkability is associated with significantly more daily steps across all age, gender, and body-mass-index categories.  However, the researchers found that women recorded comparatively less activity than men in places that are less walkable.

The study exemplifies how smartphones can deliver new insights about key health behaviors, including what the authors categorize as the global pandemic of physical inactivity….(More)”.

Lessons from Airbnb and Uber to Open Government as a Platform

Curated on Posted on by Stefaan Verhulst

Interview by Marquis Cabrera with Sangeet Paul Choudary: “…Platform companies have a very strong core built around data, machine learning, and a central infrastructure. But they rapidly innovate around it to try and test new things in the market and that helps them open themselves for further innovation in the ecosystem. Governments can learn to become more modular and more agile, the way platform companies are. Modularity in architecture is a very fundamental part of being a platform company; both in terms of your organizational architecture, as well as your business model architecture.

The second thing that governments can learn from a platform company is that successful platform companies are created with intent. They are not created by just opening out what you have available. If you look at the current approach of applying platform thinking in government, a common approach is just to take data and open it out to the world. However, successful platform companies first create a shaping strategy to shape-out and craft a direction of vision for the ecosystem in terms of what they can achieve by being on the platform. They then provision the right tools and services that serve the vision to enable success for the ecosystem[1] . And only then do they open up their infrastructure. It’s really important that you craft the right shaping strategy and use that to define the rights tools and services before you start pursuing a platform implementation.

In my work with governments, I regularly find myself stressing the importance of thinking as a market maker rather than as a service provider. Governments have always been market makers but when it comes to technology, they often take the service provider approach.

In your book, you used San Francisco City Government and Data.gov as examples of infusing platform thinking in government. But what are some global examples of governments, countries infusing platform thinking around the world?

One of the best examples is from my home country Singapore, which has been at the forefront of converting the nation into a platform. It has now been pursuing platform strategy both overall as a nation by building a smart nation platform, and also within verticals. If you look particularly at mobility and transportation, it has worked to create a central core platform and then build greater autonomy around how mobility and transportation works in the country. Other good examples of governments applying this are Dubai, South Korea, Barcelona; they are all countries and cities that have applied the concept of platforms very well to create a smart nation platform. India is another example that is applying platform thinking with the creation of the India stack, though the implementation could benefit from better platform governance structures and a more open regulation around participation….(More)”.

Madrid as a democracy lab

Curated on Posted on by Stefaan Verhulst

Bernardo Gutiérrez at OpenDemocracy: “…The launch of Decide Madrid, the city participation platform running on the Consul free software, signaled a real revolution. On the one hand, it paved the way for democracy from the bottom up, through direct and binding mechanisms. Unlike other historical participatory budgets, the 100 million Euros devoted to Decide Madrid participatory budgets in 2017 are allocated according to proposals coming from below. The proposals that get the most votes, whenever technically feasible, are approved. The platform also carries a section for “citizen proposals”. …

The Decide Madrid platform was not initially well received by the traditional neighbourhood associations, used to face-to-face participation and to mediating between citizens and government. In order to tackle this, a number of face-to-face deliberation spaces are being set up, such as the Local Forums (physical participation spaces in the districts), and also projects such as If you feel like a cat (participation for children and teenagers), or processes such as G1000, which aims at promoting collective deliberation and fostering proposals from below on the basis of a representative sample of the population, so that the participants’ diversity and plurality is guaranteed.

Most projects are being carried out with the support of the new Laboratories of Citizen Innovation of the prestigious Medialab-Prado. The Participa LAB(Collective Intelligence for Democracy), the DataLab (open data) and the InciLab (Citizen Innovation Lab) are joint public/common initiatives, acting as a bridge between local government and citizens. The Participa LAB, which is the one working more closely on participation, is collaborating with Decide Madridin a number of projects (Codat Madrid hackathons, If you feel like a cat, community lines, gamification, G1000, narrative groups…) and coordinates the Collective Intelligence for Democracy international call. InciLab has launched, among many other initiatives, the Madrid Listens project, to connect City Hall officials with citizens on concrete projects, blending disintermediation and the citizen lab philosophy.

More than 300.000 users strong, Decide Madrid is consolidating itself as the hegemonic space for participation in the city. It activates a variety of processes, debates, proposals, and projects. Its free software means that any city can adapt Consul to its needs, without any substantial investment, and set up a platform. From Barcelona to A Coruña, from Rome to Paris and Buenos Aires, dozens of institutions around the world have replicated the initial Decide Madrid core, thus setting up what Audrey Tang, Taiwan’s digital minister, calls a “liquid federation of cities”. Ada Colau, the mayor of Barcelona, praising the cooperative network of participation cities says: “It is very interesting that in Barcelona we have been able to carry out our first experience of digital participation, Decidim Barcelona, adapting Madrid’s base code. Once we have had a first proposal, we have shared it with many municipalities throughout Catalonia”.

Distributed democracy

The brain as a metaphor. A map of Hamburg (Germany) as a symbol of the networked, decentralized city. Neurons and neighbourhoods connected by flows, inevitably synchronized. Both images are to be found in Emergency, Steven Johnson’s classic book on collective intelligence processes. The city as a brain, as a whole made of decentralized nodes. The city as an open network, where any neighbourhood-node can connect with any other. Caio Vassão’s concept of a distributed city rounds the edges of the city with no centre, “networked, open, fluid, flexible, adaptable, reconfigurable”. A city where the neighbourhoods in the suburbs dialogue and relate to each other without the mediation of a historical center.

Madrid has kick-started a forceful decentralization policy. Distributed democracy in Madrid can be seen in how budgets are allocated, how city districts have multiplied their resources and partly manage cultural festivals (like the Summers in the City) and cultural projects (Madrid District).

At the same time, the launching of the Local Forums is a clear move to decentralize power and participation in the city. Through projects such as Experiment District (travelling citizen laboratories), Imagine Madrid (rethinking 10 territories) or the M.A.R.E.S project, Spain’s capital city is redrawing its neighbourhood fabric, its economic relations, and citizen involvement in decision making. The successful Medialab-Prado’s Experiment District project, which has already visited Villaverde, Moratalaz and Fuencarral, is in full expansion. It is about to even launch a global call, as dozens of cities around the world want to replicate it. Medialab-Prado, one of the city innovation centres, defines Experiment District as a set of “citizen labs for experimenting and collaborative learning in which anyone can participate”. Citizen (neighbourhood) labs based on the prototyping culture, an open and collaborative way of developing projects. Citizen (neighbourhood) labs for learning and teaching, where the result is not a perfect product, but a process that can be improved in real time through the collaboration of citizens from the Madrid neighbourhoods….(More)”

A City Is a Data Pool: Blockchains and the Crypto-City

Curated on Posted on by Stefaan Verhulst

Paper by Jason Potts, Ellie Rennie and Jake Goldenfein: “The Smart City agenda of integrating ICT and Internet of Things (IoT) informatic infrastructure to improve the efficiency and adaptability of city governance has been shaping urban development policy for more than a decade now. A smart city has more data, gathered though new and better technology, delivering higher quality city services. In this paper, we explore how blockchain technology could shift the Smart City agenda by altering transaction costs with implications for the coordination of infrastructures and resources. Like the Smart City the Crypto City utilizes data informatics, but can be coordinated through distributed rather than centralized systems. The data infrastructure of the Crypto-City can enable civil society to run local public goods, and facilitate economic and social entrepreneurship. Drawing on economic theory of transaction costs, the paper sets out an explanatory framework for understanding the kinds of new governance mechanisms that may emerge in conjunction with automated systems, including the challenges that blockchain poses for cities….(More)”.

Tackling Challenges in the Engagement of Citizens with Smart City Initiatives

Curated on Posted on by Stefaan Verhulst

Paper by Long Pham and Conor Linehan: “Smart City (SC) initiatives offer best possible outcomes to  citizens and other stakeholders when those people are  involved centrally in all stages of the project. However,  undertaking design processes that facilitate citizen  engagement often involves prohibitive challenges in cost,  design and deployment mechanisms, particularly for small  cities that have limited resources. We report on a project  carried out in Cork City, a small city in Ireland, where a  method inspired by crowdsourcing was used to involve  local participants in decisions regarding smart city  infrastructure. Academics, local government, volunteers  and civil organisations came together to collaboratively  design and carry out a study to represent local interests  around the deployment of smart city infrastructure. Our  project demonstrates a new way of translating  crowdsourcing for use in government problem-solving. It  was comparatively inexpensive, creative in design, and  flexible but collaborative in deployment, resulting in high  volume of reliable data for project prioritisation and  implementation….(More)”

Data and the City

Curated on Posted on by Stefaan Verhulst

Book edited by Rob Kitchin, Tracey P. Lauriault, and Gavin McArdle: “There is a long history of governments, businesses, science and citizens producing and utilizing data in order to monitor, regulate, profit from and make sense of the urban world. Recently, we have entered the age of big data, and now many aspects of everyday urban life are being captured as data and city management is mediated through data-driven technologies.

Data and the City is the first edited collection to provide an interdisciplinary analysis of how this new era of urban big data is reshaping how we come to know and govern cities, and the implications of such a transformation. This book looks at the creation of real-time cities and data-driven urbanism and considers the relationships at play. By taking a philosophical, political, practical and technical approach to urban data, the authors analyse the ways in which data is produced and framed within socio-technical systems. They then examine the constellation of existing and emerging urban data technologies. The volume concludes by considering the social and political ramifications of data-driven urbanism, questioning whom it serves and for what ends.

This book, the companion volume to 2016’s Code and the City, offers the first critical reflection on the relationship between data, data practices and the city, and how we come to know and understand cities through data. It will be crucial reading for those who wish to understand and conceptualize urban big data, data-driven urbanism and the development of smart cities….(More)”

Carnegie Mellon scientists use app to track foul odors in Pittsburgh

Curated on Posted on by Stefaan Verhulst

Ashley Murray at Pittsburgh Post-Gazette: “If you smell something, say something. Scientists at Carnegie Mellon University want Pittsburghers to put their collective noses to the task and report foul smells using a mobile reporting application called Smell PGH.

Since the app launched last year, more than 1,300 users have reported foul smells more than 4,300 times — most of which they’ve described as “industrial,” “sulfur” or “woodsmoke.”

The app was developed at CMU’s Community Robotics, Education and Technology Empowerment (CREATE) Lab.

“The app is really about the community,” said Beatrice Dias, project director at the CREATE Lab. “To show that you’re not alone in your negative experiences of pollution impact.”

Smartphone users can create a “smell report” within the app, which has the capability to alert the Allegheny County Health Department.

Health department spokeswoman Melissa Wade said the agency has received and followed-up on 3,000 reports generated from the app.

Users can also view a real-time map of all smell reports in and around the city. A new feature added last month allows users to go back in time and play a time-lapse animation of little colored triangles — green, yellow and red, symbolizing varying degrees of smell — that pop up and disappear as odors were reported….

“The goal is I’m trying to predict the smell in the next few hours, like a weather forecast,” Mr. Hsu said. “Let’s say today from 12 to 1 p.m. we have 10 smell reports. I can check not only the smell reports, but the data from other sensor stations around Pittsburgh, so I know during this hour what the reading is of all the air-quality related variables, like PM 2.5, like sulfur and nitrogen oxides, [and] the wind speed, the wind direction. There are a lot of parameters we need to consider.”…

Another goal of this citizen science initiative, Mr. Hsu said, is to improve communication between the public and governmental regulation agencies, like the health department.

“Before this technology if you smelled something bad, you might not be sure if this came from ambient air, your neighborhood or just traffic issues,” Mr. Hsu said. “But if you use the app, you can see a lot of your neighbors are reporting, too. And then maybe the government can use this to see the problems in a city.”…(More)”.

Local Government in China Trials Blockchain for Public Services

Curated on Posted on by Stefaan Verhulst

Wolfie Zhao at Coin Desk: “A city district in southern China is using blockchain to streamline government services for its one million residents.

Chan Cheng District, within Foshan City in Canton province, announced during an event on 23rd June the launch of a platform called Intelligent Multifunctional Identity (IMI) that lets registered local residents avoid filling repetitive personal information for different public services, presumably providing a more simple and secured process.

The newly revealed system is seen as an upgrade, incorporated to the current all-in-one workflow in the local administration.

Since 2014, the Chan Cheng District government has operated a central hub inside the city that serves as a physical portal for residents who need tax, pension, healthcare or utility services, among others. Despite offering a single source at which residents can access these services, repetitive work is needed for multiple processes.

According to the district’s announcement, residents who are able to register on and verified by the IMI platform will have the control of their personal information and can grant access to a government service they need. Using paired public and private keys, the system is also said to be able to verify users’ identity automatically without requiring them to be physically present at a service center….(More)”.

Singapore’s ‘Uber of lifesaving’ app is a simple way to stop people from dying on the street

Curated on Posted on by Stefaan Verhulst

Ariel Schwartz for  Business Insider: “If you have a heart attack on a plane, chances are decently good that a doctor or nurse onboard can provide emergency services while you wait to land. But if you collapse on a crowded city street, you might have to wait awhile for an ambulance to arrive.

Singapore’s solution: bring the plane treatment model to the streets by crowdsourcing medical help from whoever happens to be nearby.

The city-state’s population is rapidly aging, and that’s led to an uptick in the number of calls for emergency services. Getting ambulances through clogged city streets to people in need of care within 10 minutes – the approximate amount of time someone in cardiac arrest has before their prospects of survival dim -is a struggle.

A few years ago, Singapore’s Civil Defense Force (which run the public ambulance system) started testing a solution called myResponder. It’s essentially the app version of a flight attendant saying, “Is there a doctor onboard?”

When someone calls 995 (the equivalent of 911), their call is geolocated and a notification is sent out to anyone nearby who has downloaded the app. Once someone gets a notification, they can choose whether or not to accept the call for help. The app also shows the location of any nearby defibrillator machines.

The app launched in 2015. Since then, more than 15,000 medical professionals have downloaded it….(More)”

Reinvention in Middle America

Curated on Posted on by Stefaan Verhulst

New report by sparks & honey: “Conventional wisdom suggests that to peer into the crystal ball of America’s future, one should go to Silicon Valley to check out the latest start-up unicorns, or to New York or Los Angeles to scout emerging trends in fashion and food.
Middle America, on the other hand, is often described as if it’s on the margins of culture and innovation — “flyover country” — provincial, unsophisticated and stuck in the past. But Middle America is diverse and although it is not stuck in the past —rhetoric about it is.

In this culture forecast report, we spotlight the region, looking at it not through the lens of politics, ideology or outdated clichés, but rather through innovation. Key cities from Cleveland to Nashville to Louisville are reinventing themselves by embracing innovation in manufacturing, city design, healthcare, sustainability efforts and clean energy, creatively solving problems that the entire country will eventually have to confront. And they’re imbuing this reinvention with characteristic Middle American values of community, collaboration, and concern for the social impact of their actions.

Yes, portions of Middle America may have a lot of cornfields — but drone-farming is happening there. Although Nashville is still the seat of the Grand Ole Opry, it’s also emerging as a major fashion and design hub. And in Appalachia, a coal museum is powered by solar energy and out-of-work coal miners are reinventing themselves as coders. It’s even predicted that in five years, the Midwest will have more startups than Silicon Valley.

Although it’s easy to politicize and divide America, innovation is not about moving right or left. Innovation is about moving forward…(More)”
