Human Practice crowdsources physician recommendations from users’ social networks. A couple weeks ago I had the chance to attend a pitch contest here in Chicago that featured Human Practice (@HumanPractice), a local digital health startup with a unique vision for disrupting patient referrals that I found quite compelling. Founded in December 2010, Human Practice has been totally bootstrapped to date by Moses Hohman, who has an extensive background in biomedical software, and his wife Sehjin Han, herself a University of Chicago trained surgeon. Together, Moses and Sehjin interviewed hundreds of physicians and patients and one theme they found to be consistent between both was that patients want physicians recommendations they could trust, and the existing physician review sites simply did not offer evaluations that met this standard. The key differentiator of the Human Practice model is that users can get trusted referrals from individuals whom are already part of their immediate social network by connecting their Facebook accounts to the Human Practice platform.

Photo by Spencer Platt/Getty Images When something momentous is unfolding—the Arab Spring, Hurricane Sandy, Friday’s horrific elementary school shooting in Connecticut—Twitter is the world's fastest, most comprehensive, and least reliable source of breaking news. If you were on the microblogging site Friday afternoon, you were among the first to hear the death toll, watch the devastated reactions, and delve into the personal details of the man the media initially identified as a killer.

But there’s also a good chance you were taken in by some of the many falsehoods that were flying, like a letter one of the young victims purportedly wrote to his mother before the shooter entered the classroom. And, of course, all of those social media pages that were making the rounds turned out to belong to innocent people, including the real suspect’s brother.

The hoaxes and mistaken identities pale in importance next to Friday’s real tragedy, of course. Favorite QGIS Resources of the Moment | geoMusings. I’ve been dabbling more with Quantum GIS (QGIS) lately. I’m not doing anything particularly sophisticated but it’s a great viewer for some data types (SpatiaLite, GeoJSON) that aren’t supported by my commercial desktop GIS so it’s helping me validate outputs of some applications I’m writing. While I’ll never be a real cartographer, I am interested in doing a little more. Here are the resources that have been helping me the most lately… I’ll start with three blogs: Anita Graser (@underdarkgis) Nathan Woodrow (@madmanwoo) The MapBox Blog (@mapbox) The MapBox blog takes some explaining. Outside of that, I set up a Google Alert for QGIS which feeds me all kinds of things: posts from other blogs, mailing entries, StackExchange questions, and so on.

Automatically Ranking the Credibility of Tweets During Major Events. In their study, “Credibility Ranking of Tweets during High Impact Events,” authors Aditi Gupta and Ponnurangam Kumaraguru “analyzed the credibility of information in tweets corresponding to fourteen high impact news events of 2011 around the globe.” According to their analysis, “30% of total tweets about an event contained situational information about the event while 14% was spam.” In addition, about 17% of total tweets contained situational awareness information that was credible. The study analyzed over 35 million tweets posted by ~8 million users based on current trending topics. From this data, the authors identified 14 major events reflected in the tweets. These included the UK riots, Libya crisis, Virginia earthquake and Hurricane Irene, for example. “Using regression analysis, we identi ed the important content and sourced based features, which can predict the credibility of information in a tweet.

The crowd falls silent as the gun is raised, thousand of eyes staring downfield as we prepare for battle. “On your mark!” I toe the line, my breath rising in the cold November air.

And that is: Human performance and productivity. 1. Creating maps with qgis and tilemill | Klaas Nienhuis. Quite often we need to create a map for a client. Most of these maps are static but some of them are also slippy maps, like google maps. Creating these maps is a lot of work, depending on the level of detail and the scale. Nevertheless, we tend to do them by hand, over and over again. Normally we donload data from openstreetmap and edit that.

A good place to start is Generally speaking, the results are great, but take a lot of manual labor to create. This map has been created with mapbox, which is closely related to tilemill. When using tilemill, we can create maps more efficiently and make them pretty at the same time. Working with files from openstreetmap is great. After you’ve reviewed or edited your data in qgis, you can import it into tilemill.

When you’re satisfied with your style, you can export it to a static map: pdf, png or svg. This is the result of styling the map and hosting it on mapbox. Telecommuting increases work hours and blurs boundary between work and home, new study shows. With fluctuating gas prices and the increasing call for work-life balance, telecommuting has become an attractive option for busy professionals. Yet according to a new study from The University of Texas at Austin, for most employees who work remotely, telecommuting equates to working more hours.

The study, co-authored by Jennifer Glass, professor in the Department of Sociology and the Population Research Center, shows that most of the 30 percent of respondents who work from home add five to seven hours to their workweek compared with those who work exclusively at the office. They are also significantly less likely to work a standard 40 hour schedule and more likely to work overtime. In fact, most telecommuting hours occur after an employee has already put in 40 hours of work at the office. Using two nationally representative data sources -- the National Longitudinal Survey of Youth 1979 panel and special supplements from the U.S. Ernement de la Nouvelle-Calédonie. Newsmap. Radar graphs: Avoid them (99.9% of the time) Stephen Few doesn't like radar graphs, and he's not the only one who has written against them. In a recent discussion on Twitter, Jon Peltier said that they are "worse than pies" —ouch!

Even Andy Kirk, who is usually as polite as a British gentleman can be, doesn't have nice words about this kind of display. Most of the arguments against radar graphs can be summarized in a couple of sentences from this post by Graham Odds: "Even with a common scale between axes, comparing values across them remains cumbersome and error-prone. This is because rather than the simple straight-line comparison our visual perception is hard-wired to perform that is found in “conventional” chart types, comparison in radar charts requires conscious thought to mentally project a sort of arc of rotation to map a value from one axis onto another, something we are not particularly adept at.

" I agree on that, something that you may find unsurprising if you have read my book already. Época Magazine Not bad at all. 1. Measuring flow using a tiny wobbling tube. One milligram per hour: fluid flow can be measured with great precision using a tiny 'wobbling' tube with a diameter of only 40 micrometres. Thanks to a new technique, the sensor, which makes use of the 'Coriolis effect', can be made even more compact, e.g. for medical applications. Scientists at the University of Twente's MESA+ Institute for Nanotechnology have published an article on the subject in Applied Physics Letters.

Coriolis meters are often enormous instruments mounted in a pipeline to measure liquid flow accurately. Reduced to micrometre dimensions the result is a sensor that can measure extremely slow-moving small quantities of fluids. The fluid is passed through a tiny rectangular tube that is made to wobble. The Coriolis effect then causes the tube to move upwards as well, and this upward displacement is a measure of the amount of fluid flowing through it. No magnets Until now magnets have been used to bring about the wobbling motion. Industrial applications. Twitter algorithm can analyze the truthfulness of tweets. While we've seen work on an algorithm that can predict trending Twitter topics before they happen, that's no good if you're sifting through a mountain of tweets to find accurate, up-to-the-minute news. For that, you might want to look into a new paper to be published in Internet Research next month and reported on by Slate.

In it, researchers test out an algorithm designed to assess the accuracy of information posted on Twitter. The machine-learning system uses a number of parameters based on prior research which found typical signifiers that a tweet might contain valid information — for example, if it comes from an account with a lot of followers, if it contains a link, or if it's negative in tone, it's more likely to be true. Right now the algorithm apparently has an "area under the curve" (AUC) of 0.86, meaning it's closer to a perfect score of 1 than a random score of 0.5. At the intersection of big data and cloud computing: Analytics.

Two of today’s most prominent trends in healthcare – big data and cloud computing – are fated to intertwine in ways that will bolster health data analytics. Indeed, it’s already happening at UPMC. The provider has been making big use of the cloud to manage its huge and ever-growing piles of data as part of a long-term partnership with IBM to completely revamp its storage and analytics of huge volumes of patient and research data, all leading up to the medical center’s $100 million personalized care initiative, announced Oct. 1.

UPMC has a deployed a dynamic virtualized infrastructure that shortened information backup times by 20 percent and recovery times by half, officials said. IBM helped with storage and server virtualization, enabling the network to be more flexible to accommodate exponential data growth at UPMC’s 20 hospitals and 400 outpatient locations. A key part of this is a private cloud that supports mission-critical applications. Big data, to be certain. The good news? Nouveau numéro du Bulletin de surveillance sanitaire. Why is the flu more common during the winter season? Influenza, commonly known as the flu, has distinct transmission patterns around the world.

In temperate regions, influenza's occurrence peaks during the winter season, while in some tropical regions, the disease's occurrence tends to correspond with the rainy season. Linsey Marr, associate professor of civil and environmental engineering at Virginia Tech, and her colleagues, Wan Yang, of Blacksburg, Va., one of her doctoral students, and Elankumaran Subbiah, a virologist in the biomedical sciences and pathobiology department of the Virginia-Maryland Regional College of Veterinary Medicine, measured the influenza A virus survival rate at various levels of humidity.

Their study presents for the first time the relationship between the influenza A virus viability in human mucus and humidity over a large range of relative humidities, from 17 percent to 100 percent. At low humidity, respiratory droplets evaporate completely and the virus survives well under dry conditions. Using Google Flu data, researchers create model of flu outbreaks.

Debating The Value of Tweets For Disaster Response (Intelligently) With every new tweeted disaster comes the same old question: what is the added value of tweets for disaster response? Only a handful of data-driven studies actually bother to move the debate beyond anecdotes. It is thus high time that a meta-level empirical analysis of the existing evidence be conducted. Only then can we move towards a less superficial debate on the use of social media for disaster response and emergency management. In her doctoral research Dr. In this separate study, over 64,000 tweets generated during Thailand’s major floods in 2011 were analyzed.

In this more recent study, researchers mapped flood-related tweets and found a close match between that resulting map and the official government flood map. Shifting from floods to fires, this earlier research analyzed some 1,700 tweets generated during Australia’s worst bushfire in history. Finally, this recent study analyzed over 35 million tweets posted by ~8 million users based on current trending topics. PS.
