Hoe Big Data u klein houden. Met een tweetende trol in het Witte Huis, Facebook dat experimenteert met zijn gebruikers en de politie die mensen arresteert nog voor ze de misdaad gepleegd hebben, verbaast het niet dat ‘1984’ weer een bestseller is. dS Weekblad onderzoekt dit weekend hoe big data ons zien, en vooral wat er met die gegevens gebeurt.

Hoe Big Data u klein houden

‘Ik arresteer u voor de toekomstige moord op uw vrouw en haar minnaar die vandaag om 8.04 uur zou plaatsvinden.’ (Uit: ‘Minority Report’ van Steven Spielberg) Politiewerk in de onvoltooid verleden toekomende tijd en arrestaties met voorbedachten rade? Wie vandaag op een lezing voor computerwetenschappers nog durft uit te pakken met citaten van Tom Cruise, wordt gegarandeerd op een geeuw onthaald. In de scifiprent uit 2002 gebruikt een eliteploegje agenten futuristische wezens – half robot, half mens – om in Washington moorden te voorspellen. De realiteit heeft de sciencefiction intussen ingehaald. Information is Beautiful. Geopunt Vlaanderen - historische kaarten.

All of the World's Money and Markets in One Visualization

Strangely enough, there are multiple answers to this question, and the amount of money that exists changes depending on how we define it. The more abstract definition of money we use, the higher the number is. In this data visualization of the world’s total money supply, we wanted to not only compare the different definitions of money, but to also show powerful context for this information. That’s why we’ve also added in recognizable benchmarks such as the wealth of the richest people in the world, the market capitalizations of the largest publicly-traded companies, the value of all stock markets, and the total of all global debt. The end result is a hierarchy of information that ranges from some of the smallest markets (Bitcoin = $5 billion, Silver above-ground stock = $14 billion) to the world’s largest markets (Derivatives on a notional contract basis = somewhere in the range of $630 trillion to $1.2 quadrillion).

4 Maps Crucial to Understanding Europe's Population Shift

Europe’s population is shifting to the Northwest. The GDP in its more easterly nations seems to be booming, while the countryside and many smaller cities continue to empty at the expense of the great conurbations. And while Europe’s southern nations continue to suffer under austerity, cities around the Mediterranean are nonetheless among the fastest growing in terms of population. These are just some of the key demographic shifts outlined in a recent report [PDF] from Bloomberg Philanthropies and LSE Cities. While the report focuses overall on the 155 submissions made to last year’s first ever Europe-based Bloomberg Philanthropies Mayors Challenge, its data provides a fascinating snapshot of a continent on the move. Go East? While they’re often depicted as the continent’s poor relations, it’s actually the states of Central and Eastern Europe where per capita GDP has grown fastest.

[Onderzoek] ‘Jongeren juist socialer door social media!’ - Nieuws.Social: Social Media Marketing: social business, onderzoek, cijfers, trends en meer

Het is een bekend beeld: jongeren die alleen nog aandacht hebben voor hun beeldscherm. Maar mediaonderzoeker Marjon Schols ontkracht waarschuwingen dat ze hierdoor minder sociaal zouden worden. Uit haar promotieonderzoek onder duizenden jongeren blijkt dat alledaagse online activiteiten juist positief zijn voor de sociale cohesie. Jongeren die veel tijd besteden aan online sociale contacten zijn sterker verbonden met hun sociale netwerken. Ook participeren ze meer in de samenleving. Negatieve gevolgen De eventuele negatieve gevolgen van het internetgebruik onder jongeren krijgen veel aandacht. Sterk verbonden In haar proefschrift Young, Online and Connected. How and Why Parents Guide the Media Use of Young Children. Several literature reviews (e.g., Singer and Singer 2011) have described the young child’s gradual development as a media consumer, i.e., how the child processes media content and handles the devices.

How and Why Parents Guide the Media Use of Young Children

Despite their lack of essential perceptual and symbolic understanding and fine motoric skills, even infants are already attentive to media content that matches their social ideas, expectations, and capacities to interpret those media (Barr et al. 2008; Valkenburg and Vroone 2004). Although younger children often experience difficulties in using apps on smart mobile devices, which includes uncontrolled swiping, tapping icons incorrectly, accidentally exiting the app and/or not being able to hear audible gaming instructions, many of them still are motivated to continue to use the device (Chiong and Shuler 2010). Moreover, through age 7, children are also honing their fine-motor skills, which makes it gradually easier for them to manipulate touchscreens, small keys, gadgets and controllers.

Climate spirals. Effectively communicating climate change is a challenge.

Climate spirals

The animated climate spiral is a different way to show the historically observed changes and resonates with a broad audience. The original version quickly went viral, being seen millions of times on facebook and twitter. A version was even used in the opening ceremony of the Rio Olympics! This page will provide regularly updated versions of the climate spiral for several different aspects of the climate. The graphics are free to use with appropriate credit – just click the links for the full versions to download. Current version of global temperature spiral Three-dimensions Several people suggested a 3d version of the spiral with the third dimension representing time. Future projections of temperature Jay Alder from the USGS has created a similar spiral visualisation for a climate model simulation for the historical period and the future, assuming high future emissions.
