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.
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.”
The Social Affordances of the Internet for Networked Individualism
Paper by NetLab (Toronto University) scholars in the latest issue of the Journal of Computer-Mediated Communication: “We review the evidence from a number of surveys in which our NetLab has been involved about the extent to which the Internet is transforming or enhancing community. The studies show that the Internet is used for connectivity locally as well as globally, although the nature of its use varies in different countries. Internet use is adding on to other forms of communication, rather than replacing them. Internet use is reinforcing the pre-existing turn to societies in the developed world that are organized around networked individualism rather than group or local solidarities. The result has important implications for civic involvement.”
Sanitation Hackathon
New 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.”

Investigating Terror in the Age of Twitter
Michael Chertoff and Dallas Lawrence in WSJ: “A dozen years ago when the terrorists struck on 9/11, there was no Facebook or Twitter or i-anything on the market. Cellphones were relatively common, but when cell networks collapsed in 2001, many people were left disconnected and wanting for immediate answers. Last week in Boston, when mobile networks became overloaded following the bombings, the social-media-savvy Boston Police Department turned to Twitter, using the platform as a makeshift newsroom to alert media and concerned citizens to breaking news.
Law-enforcement agencies around the world will note how social media played a prominent role both in telling the story and writing its eventual conclusion. Some key lessons have emerged.”
China identified as main source behind cyber-espionage
Washington Post: “Analyses of hundreds of documented data breaches found that hackers affiliated with the Chinese government were by far the most energetic and successful cyberspies in the world last year, according to a report to be issued Tuesday by government and industry investigators.
Although hackers with financial motives are the most common source of data breaches worldwide, China dominated the category of state-affiliated cyber-espionage of intellectual property, said the 2013 Data Breach Investigations Report. The report was issued by Verizon’s RISK Team and 18 partners, including officials from the United States and several foreign governments.
Of 120 incidents of government cyber-espionage detailed in the report, 96 percent came from China; the source of the other 4 percent was unknown, it said.”
Reinvent Regulation
Reinvent Roundtable that will take place on April 23, 2013 11:00 am PT : “Tim O’Reilly has some big ideas about how to dramatically modernize the entire notion of government regulation, particularly “algorithmic regulation” that harnesses computer power, much like top tech companies in Silicon Valley, to oversee the financial industry, which is using those same tools. This roundtable features some top talent from the Valley to apply their brains to figuring out how we could reinvent much more iterative regulation that constantly gets refined through analyzing data and processing feedback loops – much like Google refines its search techniques. In fact, we’ll have a top person from Google Search as well as someone from the US Treasury Department to work on these ideas. Watch Now →”

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.”
Newark's Cory Booker: Social Media Can Help Fix Broken Government
Internet Evolution on Cory Booker’s panel at Ad Age Digital Conference: “Social media have been a part of a transformation of the City of Newark from a butt of jokes to a community experiencing economic growth, Booker told the Ad Age conference. Newark has a population of 300,000 in a state with 9 million people, and yet, Newark has a third of the economic growth in the state. The city population is growing for the first time in 60 years.
Social media can be a big part of the cure for government that has become unresponsive to the needs of its citizens, Booker said. He quoted California Lt. Governor Gavin Newsom, who uses the phrase “vending machine government.” Citizens pay for government services, and get prepackaged offerings in return. “If you don’t like what you get, you shake the vending machine,” Booker said…
When people lean back and disengage, government becomes unresponsive. But social media provide the tools for citizens to collaborate with government. “We have all these tools pulling government away from citizens,” Booker said. These include special interest groups and moneyed corporate lobbies. “But social media brings us closer.”
Twitter helped Newark rebuild its reputation. The city had been a butt of jokes for years. When Conan O’Brien made a joke at Newark’s expense, Booker replied with an online video that said O’Brien was now on the no-fly list at Newark Airport. The TSA got into the act, issuing a statement that Booker didn’t have that power. Then-Secretary of State Hillary Clinton followed up with a plea for Booker and O’Brien to just get along.
And it’s not just a matter of public relations; social media have helped improve Newark in concrete ways — Newark’s government is more effective. For example, its inspectors are vastly more efficient at finding violations when citizens can use social media to point up problems, Booker said.
Video can be an even more powerful tool for getting a message out than microblogging services such as Twitter, Booker said. And that led to discussion of Booker’s startup, #waywire. The beta video service, updated this week to focus on video curation, is a place where people can collect and share online video.”
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.
- “To better address and manage crisis events via social media, the American Red Cross looked to Dell to understand how to best scale their efforts, establish processes and training and build their own listening command center.
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.”
Data for the Boston Marathon Investigation Will Be Crowdsourced
WIRED: “The investigation of Monday’s deadly twin bombings in Boston will rely to an extraordinary extent on crowdsourced surveillance, provided by Marathon spectators’ cellphone photos, Vine videos, and Instagram feeds….There are limits to the crowdsourcing. The data used in the investigation will be crowdsourced. The investigation will not be. A crowdsourced investigation runs a high risk of becoming a witchhunt, as we saw in the Newton shooting spree.”
