off-topic: The first-ever picture of a black hole

Just a few years ago, Katie Bouman (then a PhD student at MIT) presented this TED talk about the massive collective research effort involved in the Event Horizon Telescope Collaboration. Three years latter, today, this collaboration announced the first-ever picture of a black hole. Katie led the creation of a new imaging algorithm that helped make this possible.

Yep, they have found a way to register the image of a black hole that is about 55 million light years away from Earth. The method is truly inventive, involving an array of telescopes across the globe, atomic clocks, cutting edge machine learning and more than 5 petabytes of data. You can see more about it in this short video or in the public announcement made today.

I know this is a bit off-topic in this blog but my inner nerd child is too excited to let this one pass. This is a big day.

Hans Rosling passed away today

"We are extremely sad to announce that Professor Hans Rosling died this morning. Hans suffered from a pancreatic cancer which was diagnosed one year ago. He passed away early Tuesday morning, February 7, 2017, surrounded by his family in Uppsala, Sweden."
This information comes from Gapminder, which Hans was one the founders in 2006.

Hans was incredibly knowledgeable of social and economic dimensions behind population and health issues. He was also and incredible speaker who gave a great contribution to the public understanding of population studies (his Ignorance Project is one of my favorites). Also thanks to the great relevance of the Gapminder project, he became internationally famous because of his TED talks, to the point he became know as the “Mick Jagger" of TED.

I've included below a few links to some of our previous posts on Hans Rosling's work, but he has has many more incredible videos, material out there on the web that will keep a beautiful memory of Hans and his work.

My sentiments to the Rosling's family and close friends.

WTF

I've never felt so ashamed of being American... and I'm not even American.

There will be a flood of articles on this issue. I have really liked these two so far.

off-topic: Explore & compare place names from 13 countries

Open Data Zurich points out to this interactive application to explore names of places in 13 countries. The data comes from OpenStreetMap.

On a curious note on the catholic roots of Brazil, a bit over 10% of all 5565 municipalities in Brazil are named after a saint. This proportion is less than 1.5% in Italy.

How Internet Censorship Works in China, or how to create a brilliant research design

A few of months ago, Prof Gary King presented in Oxford a research project where he and his group (J. Pan and M. Roberts) analyze how internet censorship in China works. Judging by his presentation, this is one of the most well designed research pieces I have seen, specially considering the complexity of the topic and the difficulties in grasping censorship practices in a sensitive context. 

This post may look a bit off-topic considering the scope of this blog but I believe we always have something to learn from reading/listening to good research, even if it's not in our field of expertise.  You may watch King's presentation here, and check the papers below. 


King, G., Pan, J., & Roberts, M. E. (2013). How censorship in China allows government criticism but silences collective expression. American Political Science Review, 107(02), 326-343. (ungated version)

Abstract

We offer the first large scale, multiple source analysis of the outcome of what may be the most extensive effort to selectively censor human expression ever implemented. To do this, we have devised a system to locate, download, and analyze the content of millions of social media posts originating from nearly 1,400 different social media services all over China before the Chinese government is able to find, evaluate, and censor (i.e., remove from the Internet) the large subset they deem objectionable. Using modern computer-assisted text analytic methods that we adapt to and validate in the Chinese language, we compare the substantive content of posts censored to those not censored over time in each of 85 topic areas. Contrary to previous understandings, posts with negative, even vitriolic, criticism of the state, its leaders, and its policies are not more likely to be censored. Instead, we show that the censorship program is aimed at curtailing collective action by silencing comments that represent, reinforce, or spur social mobilization, regardless of content. Censorship is oriented toward attempting to forestall collective activities that are occurring now or may occur in the future --- and, as such, seem to clearly expose government intent.


King, G., Pan, J., & Roberts, M. E. (2014). Reverse-engineering censorship in China: Randomized experimentation and participant observation. Science, 345(6199), 1251722. (ungated version)

Abstract
Existing research on the extensive Chinese censorship organization uses observational methods with well-known limitations. We conducted the first large-scale experimental study of censorship by creating accounts on numerous social media sites, randomly submitting different texts, and observing from a worldwide network of computers which texts were censored and which were not. We also supplemented interviews with confidential sources by creating our own social media site, contracting with Chinese firms to install the same censoring technologies as existing sites, and—with their software, documentation, and even customer support—reverse-engineering how it all works. Our results offer rigorous support for the recent hypothesis that criticisms of the state, its leaders, and their policies are published, whereas posts about real-world events with collective action potential are censored.

Brazilian Elections

Big day for Brazil tomorrow with the elections. It's hard to say we don't have a solid democracy.
