Communicability reveals a transition to coordinated behavior in multiplex networks

Communicability reveals a transition to coordinated behavior in multiplex networks | Complexity | Scoop.it

We analyze the flow of information in multiplex networks by means of the communicability function. First, we generalize this measure from its definition from simple graphs to multiplex networks. Then, we study its relevance for the analysis of real-world systems by studying a social multiplex where information flows using formal-informal channels and an air transportation system where the layers represent different air companies. Accordingly, the communicability, which is essential for the good performance of these complex systems, emerges at a systemic operation point in the multiplex where the performance of the layers operates in a coordinated way very differently from the state represented by a collection of unconnected networks.

Large datasets from Google Research

Large datasets from Google Research | Complexity | Scoop.it

50,000 relations from Wikipedia. 100,000 feature vectors from YouTube videos. 1.8 million historical infoboxes. 40 million entities derived from webpages. 11 billion Freebase entities in 800 million web documents. 350 billion words’ worth from books analyzed for syntax.
These are all datasets that we’ve shared with researchers around the world over the last year from Google Research.
But data by itself doesn’t mean much. Data is only valuable in the right context, and only if it leads to increased knowledge. Labeled data is critical to train and evaluate machine-learned systems in many arenas, improving systems that can increase our ability to understand the world. Advances in natural language understanding, information retrieval, information extraction, computer vision, etc. can help us tell stories, mine for valuable insights, or visualize information in beautiful and compelling ways.

That’s why we are pleased to be able to release sets of labeled data from various domains and with various annotations, some automatic and some manual. Our hope is that the research community will use these datasets in ways both straightforward and surprising, to improve systems for annotation or understanding, and perhaps launch new efforts we haven’t thought of.

Iraq Body Count

Iraq Body Count | Complexity | Scoop.it

Iraq Body Count (IBC) records the violent civilian deaths that have resulted from the 2003 military intervention in Iraq. Its public database includes deaths caused by US-led coalition forces and paramilitary or criminal attacks by others.

IBC’s documentary evidence is drawn from crosschecked media reports of violent events leading to the death of civilians, or of bodies being found, and is supplemented by the careful review and integration of hospital, morgue, NGO and official figures.

Systematically extracted details about deadly incidents and the individuals killed in them are stored with every entry in the database. The minimum details always extracted are the number killed, where, and when.

Confusion about the numbers produced by the project can be avoided by bearing in mind that:

IBC’s figures are not ‘estimates’ but a record of actual, documented deaths.IBC records solely violent deaths.IBC records solely civilian (strictly, ‘non-combatant’) deaths.IBC’s figures are constantly updated and revised as new data comes in, and frequent consultation is advised.

IBC builds on innovative uses of new technologies without which this citizens’ initiative would be impossible. The project was founded in January 2003 by volunteers from the UK and USA who felt a responsibility to ensure that the human consequences of military intervention in Iraq were not neglected.

Finally, IBC could not exist without the journalists and media support workers, Iraqi and international, who labour to report war’s daily carnage at the risk, and all too often the cost, of their health or their lives.

Unlocking the link between brain power, personality and life chances

Unlocking the link between brain power, personality and life chances | Complexity | Scoop.it

Newly released data allows researchers to review cognitive function and personality traits across the whole life course, from ages 16 to 102.

Wave 3 of Understanding Society - the UK Household Longitudinal Study - includes the results of testing the cognitive ability of nearly 50,000 adults and 4,500 children aged 10 to 15. The study integrates 18 years of data from the British Household Panel Survey (BHPS) and Wave 3 provides up to 21 years of evidence about the changing nature of our society, individuals' circumstances and behaviours.

Nick Daniels's curator insight, November 25, 2014 7:28 PM

Although this article mentions the use of Big Five traits, it incorrectly informs its audience that these traits of conscientiousness, agreeableness, neuroticism, extraversion, and openness are "believed to be with us for life." David Myers continually expresses in his book, "Exploring Psychology" that personality traits are 50% genetic and 50% dependent on external factors, (Myers, 2005). The three type of reciprocal influences that make up personality are biological influences, psychological influences, and social-cultural influences, (Myers, 2005). With the combination of psychological influences such as learned responses, and social-cultural influences of childhood experiences and social support, it is hard to state that personality is cemented by age and going to be relavent in another 21 years. Our world is forever changing, creating different 16 to 102 year old personalities every generation. As this source did use nearly 55,000 test subjects, of which you can be sure they included diverse groups, it can be considered irrelevant because of the fact that they believe personality traits are set in stone.

Australia's National Public Toilet Map

Australia's National Public Toilet Map | Complexity | Scoop.it

The National Public Toilet Map shows the location of more than 14,000 public and private public toilet facilities across Australia. Details of toilet facilities can also be found along major travel routes and for shorter journeys as well. Useful information is provided about each toilet, such as location, opening hours, availability of baby change rooms, accessibility for people with disabilities and the details of other nearby toilets.

The database (known as the National Public Toilet Database) owned by and provided on behalf of the Commonwealth including any updates provided by or on behalf of the Commonwealth, records some or all of the following details for public toilets in Australia:

(a) toilet name;

(b) address;

(c) latitude and longitude;

(d) general toilet features;

(e) location;

(f) accessibility;

(g) opening hours;

(h) additional features (e.g. showers, baby change facilities etc);

(i) notes (e.g. coin operated showers etc).

Tate Art Collection metadata

Tate Art Collection metadata | Complexity | Scoop.it

ARTIST ROOMS is an inspirational collection of modern and contemporary art acquired for the nation through the generosity of Anthony d'Offay. It includes major installations and works by artists of international renown.

Here we present the metadata for around 70,000 artworks that Tate owns or jointly owns with the National Galleries of Scotland as part of ARTIST ROOMS. Metadata for around 3,500 associated artists is also included.

Each artist has his or her own JSON file. They are found in the artists folder, then filed away by first letter of the artist’s surname.

Artworks are found in the artworks folder. They are filed away by accession number. This is the unique identifier given to artworks when they come into the Tate collection. In many cases, the format has significance. For example, the ar accession number prefix indicates that the artwork is part of ARTIST ROOMS collection. The n prefix indicates works that once were part of the National Gallery collection.

Data from: Can Self-Control Explain Avoiding Free Money? Evidence from Interest-Free Student Loans

Data from: Can Self-Control Explain Avoiding Free Money? Evidence from Interest-Free Student Loans | Complexity | Scoop.it

This paper uses insights from behavioral economics to explain a particularly surprising borrowing phenomenon: one in six undergraduate students offered interest-free loans turns them down. Models of impulse control predict that students may optimally reject subsidized loans to avoid excessive consumption during school. Using the National Postsecondary Student Aid Study, we investigate students' take-up decisions and identify a group of students for whom the loans create an especially tempting liquidity increase. Students who would receive the loan in cash are significantly more likely to turn it down, suggesting that consumers choose to limit their liquidity in economically meaningful situations.
