Analyzing social media use can help predict, track and map obesity rates


Statement from the Boston Children’s Hospital: “The higher the percentage of people in a city, town or neighborhood with Facebook interests suggesting a healthy, active lifestyle, the lower that area’s obesity rate. At the same time, areas with a large percentage of Facebook users with television-related interests tend to have higher rates of obesity. Such are the conclusions of a study by Boston Children’s Hospital researchers comparing geotagged Facebook user data with data from national and New York City-focused health surveys.
journal.pone.0061373.g002
Together, the conclusions suggest that knowledge of people’s online interests within geographic areas may help public health researchers predict, track and map obesity rates down to the neighborhood level, while offering an opportunity to design geotargeted online interventions aimed at reducing obesity rates.
The study team, led by Rumi Chunara, PhD, and John Brownstein, PhD, of Boston Children’s Hospital’s Informatics Program (CHIP), published their findings on April 24 in PLOS ONE. The amount of data available from social networks like Facebook makes it possible to efficiently carry out research in cohorts of a size that has until now been impractical.”
 

Visual argumentation


Volta: “Visualising arguments helps people assemble their throughts and get to grip with complex problems according to The Argumentation Factory, based in Amsterdam. Their Argument Maps, constructed for government agencies, NGOs and commercial organizations, are designed to enable people to make better decisions and share and communicate information.
Dutch research organisation TNO, in association with The Argumentation Factory, have launched the European Shale Gas Argument Map detailing the pros and cons of the production of shale gas for EU member states with shale gas resources. Their map is designed to provide the foundation for an open discussion and help the user make a balaced assessment.”

Procurement needs better data now


Howard Rolfe, procurement director for East of England NHS Collaborative Procurement Hub, in The Guardian: “Knowledge management is fundamental to any organisation and procurement in the NHS is no exception. Current systems are not joined up and don’t give the level of information that should be expected. Management in many NHS trusts cannot say how effective procurement is within their organisation because they don’t have a dashboard of information that tells them, for example, the biggest spend areas, who is placing the order, what price is paid and how that price compares.
Systems now exist that could help answer these questions and increase board and senior management focus on this area of huge spend….The time for better data is now, the opportunity is at the top of political and management agendas and the need is overwhelming. What is the solution? The provision of effective knowledge management systems is key and will facilitate improvements in information, procurement and collaborative aggregation by providing greater visibility of spend and reduction of administrative activity.”

Sanitation Hackathon


SanitationNew York Times: “Because of the rapid spread of cellular phones, mobile technology has previously been used to address a variety of problems in the developing world, including access to financial services, health care information and education. But toilets were another matter….Building on a process that had previously been employed to address problems in supplying clean water to people in poor areas, the World Bank turned its attention to sanitation. Over six months last year, it solicited ideas from experts in the field, as well as software developers. The process culminated in early December with the actual hackathon — two days in which more than 1,000 developers gathered in 40 cities worldwide to work on their projects….After the event in Washington, the winners of the hackathon are set to travel to Silicon Valley for meetings with venture capitalists and entrepreneurs who are interested in the issue. The World Bank does not plan to invest in the projects, but hopes that others might.”

Crowd diagnosis could spot rare diseases doctors miss


New Scientist: “Diagnosing rare illnesses could get easier, thanks to new web-based tools that pool information from a wide variety of sources…CrowdMed, launched on 16 April at the TedMed conference in Washington DC, uses crowds to solve tough medical cases.

Anyone can join CrowdMed and analyse cases, regardless of their background or training. Participants are given points that they can then use to bet on the correct diagnosis from lists of suggestions. This creates a prediction market, with diagnoses falling and rising in value based on their popularity, like stocks in a stock market. Algorithms then calculate the probability that each diagnosis will be correct. In 20 initial test cases, around 700 participants identified each of the mystery diseases as one of their top three suggestions….

Frustrated patients and doctors can also turn to FindZebra, a recently launched search engine for rare diseases. It lets users search an index of rare disease databases looked after by a team of researchers. In initial trials, FindZebra returned more helpful results than Google on searches within this same dataset.”

White House: Unleashing the Power of Big Data


Tom Kalil, Deputy Director for Technology and Innovation at OSTP : “As we enter the second year of the Big Data Initiative, the Obama Administration is encouraging multiple stakeholders, including federal agencies, private industry, academia, state and local government, non-profits, and foundations to develop and participate in Big Data initiatives across the country.  Of particular interest are partnerships designed to advance core Big Data technologies; harness the power of Big Data to advance national goals such as economic growth, education, health, and clean energy; use competitions and challenges; and foster regional innovation.
The National Science Foundation has issued a request for information encouraging stakeholders to identify Big Data projects they would be willing to support to achieve these goals.  And, later this year, OSTP, NSF, and other partner agencies in the Networking and Information Technology R&D (NITRD) program plan to convene an event that highlights high-impact collaborations and identifies areas for expanded collaboration between the public and private sectors.”

Taking Open Government to the Next Level


Carl Fillichio who heads the Labor Department’s Office of Public Affairs at (Work in Progress):  “Since we published a department-wide API two years ago, developers across the country have used it to create apps that educate users about workplace safety and health, employers’ compliance with wage and hour laws, and improving employment opportunities for disabled workers, just to name a few!
Releasing data through an API was a big step forward, but it was not exactly groundbreaking.  However, since then, my team has been working hard to develop software development kits that are truly innovative because they make using our API even easier.
These kits (also known as SDKs) contain application code for six different platforms − iOS, Android, Blackberry, .Net, PHP and Ruby − that anyone creating a mobile or Web-based app using our data could incorporate. By using the kits, experienced developers will save time and novice developers will be able to work with DOL data in just a few minutes…. All of these kits can be downloaded from our developer site. Additionally, in keeping with the federal digital government strategy, each has been published as an open source project on github, a popular code-sharing site. For a list of federal APIs that are supported by our kits, check the github repository’s wiki page. This list will be updated as the kits are tested with additional federal APIs.”
 

Public health, disaster recovery and social media


Janice Jacobs:  “Increasingly, social media is playing a key role in helping to ease the heavy burden of these tragedies by connecting individuals and communities with each other and with critical resources…
Social media, in its simplest form, can notify the masses in real-time about situations that are happening or are about to happen.

  • In August 2011, several New Yorkers learned of an earthquake on Twitter prior to feeling it. From the D.C. area, tweets began popping up in droves almost 30 seconds before anyone felt the tremors in New York City, and ahead of any media reports about it. Twitter said that more than 40,000 earthquake-related tweets were sent within a minute of the earthquake’s manifestation…...

Social media can be used to identify trouble spots and to react quickly during emergencies.

Social media can be used to foster communication among various healthcare, aid, government agencies and individuals.

  • Cory Booker, Mayor of Newark, NJ, a prolific Twitter user, consistently tweeted helpful information for the Newark community following Hurricane Sandy in late October 2012.”

 

Surfing Logs Reveal Global Eating Patterns


From the The Physics arXiv Blog:  “The way we view online recipes reveals how our eating habits change over time, say computational sociologists….it’s no surprise that computational sociologists have begun to mine the data associated with our browsing habits to discover more about our diets and eating habits. Last year we looked at some fascinating work examining networks of ingredients and the flavours they contain, gathered from online recipe websites.  It turns out this approach gives fascinating insights into the way recipes vary geographically and into the possibility of unexplored combinations of flavours.
Today, Robert West at Stanford University and Ryen White and Eric Horvitz from Microsoft Research in Redmond, take a deeper look at the electronic trails we leave when we hunt for food on the web. They say the data reveals important trends in the way our diets change with the season, with our geographical location and with certain special days such as Thanksgiving and Christmas. And they conclude that the data could become an important tool for monitoring public health.”

Digital engagement: time to shift attention toward use and usefulness


Geoff Mulgan: “The last few years have brought a cornucopia of innovation around data, with millions of data sets opened up, and big campaigns around transparency, all interacting with the results of a glut of hackathons, appathons and the like. Linked to this has been the explosion of creativity around digital tools for civic engagement and local government….
There are also big questions to ask about digital technologies and public services – and in particular why so few public services have been radically redesigned. This has been talked about for as long as I can remember – and it’s not hard to map out how a transformed health, welfare or transport system could work if you started afresh. But with a few exceptions (like tax) this isn’t happening in any of the big public services anywhere. I’ll be writing some blogs soon about how we might accelerate this kind of systemic change.
In the meantime there are some more pragmatic questions to ask about what is and isn’t working.  A pattern is becoming clear which poses a challenge to the enthusiasts, and to funders like us.  In essence it’s this: there has been brilliant progress on the supply side – opening up data, and multiplying tools and apps of all kinds. But there has been far less progress on the demand and use side. The result is that thousands of promising data sets, apps and sites remain unused; and a great deal of creativity and energy has gone to waste.
The reasons are fairly obvious when you think about it. This is a movement driven by enthusiasts who have tended to assume that supply will create its own demand (sometimes it does – but not often).  Most of the practitioners are interested in the technical challenges of design, and a measure of their success is that for most applications there are readily accessible tools now available. Yet the much bigger challenges lie around use: how to develop attractive brands; how to promote and market; how to shape design to fit how people will actually use the services; how to build living communities.”
