Cartographie mondiale des réseaux sociaux - été 2013

Cartographie mondiale des réseaux sociaux - été 2013
Les chiffres sur l’utilisation des réseaux sociaux sont en perpétuelle évolution. Rappelez-vous par exemple l’époque ou MySpace était le 4ème site le plus visité du monde (2005). Le blogueur Vincenzo Cosenza livre régulièrement une étude sur les usages mondiaux des réseaux sociaux. Celle-ci se base sur les relevés du service Alexa et sur Google Trends. Ce n’est pas d’une précision parfaite mais les relevés donnent d’excellentes tendances. La principale observation est la montée en puissance de Facebook qui cannibalise une grande partie des ses concurrents. Il est néanmoins intéressant de constater que certains réseaux souvent méconnus dans la zone Europe-Amérique ont une vraie communauté d’utilisateurs. Impossible de ne pas mentionner non plus QZone et ses 603 millions de visiteurs uniques mensuels. Dernier réseau original, Draugiem qui est le media social le plus populaire en Lettonie, il compterait 2,6 millions d’inscrits. Pour rappel, voici l’évolution depuis 2009 en GIF : Related:  cartes diverses / à classerle web

The Best Map Ever Made of America's Racial Segregation | Wired Design Last year, a pair of researchers from Duke University published a report with a bold title: “The End of the Segregated Century.” U.S. cities, the authors concluded, were less segregated in 2012 than they had been at any point since 1910. But less segregated does not necessarily mean integrated–something this incredible map makes clear in vivd color. The map, created by Dustin Cable at University of Virginia’s Weldon Cooper Center for Public Service, is stunningly comprehensive. This is the most comprehensive map of race in America ever created. White people are shown with blue dots; African-Americans with green; Asians with red; and Latinos with orange, with all other race categories from the Census represented by brown. “There are a lot of moving parts in this process, so this can cause different shades of color to appear at different zoom levels in really dense areas, like you see in NYC,” Cable explains. Looking at the map, every city tells a different story. Go Back to Top.

At the intersection of journalism, data science, and digital media: How can j-schools prep students for the world they’re headed into? Editor’s note: Two journalism educators — Amy Schmitz Weiss of San Diego State and Cindy Royal of Texas State — have provided their own lenses on how journalism education might be reshaped to match the current media landscape students are graduating into. Conversations have been abuzz lately online and offline about the role of Big Data and data science in a variety of fields — from the pharmaceutical industry to the news industry. Data is all around us and it will only become more pervasive as digital technologies advance and our daily lives become centered on these two worlds. As educators, are we preparing our students to be able to manage these two worlds of data science and digital media together effectively and accurately? Specifically, journalism and mass communication programs are at a fork in the road — they can either sit back and watch or take an active role in transforming how our students can enter a new, digital-savvy competitive workforce. A new realm of collaboration

Les cartes de Pratt, pour un premier (sur)vol du monde de Corto Maltese Le voyage est au coeur de la célèbre oeuvre d’Hugo Pratt, Corto Maltese. En 2011, la Pinacothèque de Paris a organisé une exposition autour du Voyage imaginaire d’Hugo Pratt, entremêlant les influences littéraires sur l’oeuvre d’Hugo Pratt, son travail d’aquarelliste et ses planches de bande dessinée (voir la vidéo d’un entretien avec Hugo Pratt autour de cette exposition). Le personnage de Corto Maltese, aventurier et marin, permettait à l’exposition de montrer notamment la représentation des îles et des océans dans l’oeuvre de Corto Maltese. Prolongeant le questionnement sur Corto Maltese, Aymeric Landot vous propose un autre regard sur le monde imaginaire d’Hugo Pratt dans son article publié dans la revue Spécimen (n°2, 2012) : “Pratt a ancré son oeuvre dans un temps charnière où la vapeur remplace la voile, où les forces de l’Europe se répandent sur le monde, où les fumées industrielles métamorphosent les pratiques guerrières. “Les Cartes de Pratt” (article au format PDF)

All the Rivers in the Continental US: An Explorable Map Just one look at Google engineer Nelson Minar’s river map of the continental US and it’s impossible to deny this is a country absolutely filled with waterways. He says he worked just a few weeks creating the extensive map, which is both beautiful for its artery-like depiction of the countries life-giving river systems, and fascinating to explore in the way it demonstrates the nation’s topography through the system’s many paths. See Also Vintage Maps Trace the Meandering Mississippi Observing the way rivers are spread across the US reveals the many mountain ranges and valleys that crisscross the country. Nelson’s map comes to us in a number of explorable vector-based versions and – as the files are simply to large to display – as beautiful fully detailed renderings on Flickr.

Archives | If you have picked up this issue of PM magazine and are younger than 30, you are likely already an expert at navigating social media and social networking in your personal life. But whether you've struggled to understand blogs and Twitter or find them old hat, applying them to the daily practice of government is still a valid question. Whether you see yourself as old-fashioned or on the cutting edge, if you aren't using tools like LinkedIn, Facebook, or Plaxo at work, you may soon be called a dinosaur for not connecting with the vast number of potential contacts in your extended network worldwide. And if your organization has not created a fan page on these sites, you may be missing out on the fastest-growing, hottest way to communicate and connect with your community.

Where do the world's atheists live? I think that this is something that might have some regionality (hello, Bible Belt!), the biggest trend you'd see would simply be a belief spectrum aligning pretty well with rural=> urban. The less urban, the fewer atheists. So if you looked at any single region like the upper midwest, or like California/Nevada, each would appear overall to be pretty non-atheist, but with deep brown pockets of atheism in the cities — you know, where more people actually live. But I'll admit right off the bat that this is my speculation, I don't have a dataset (or a map) to back me up. At first, the Saudi thing surprised me too, but then I considered a couple of things. What I find odd and rather suspect about the map is the large number of populous countries with good communication infrastructure that are not tracked.

How to Optimize Social Networks for Local SEO When it comes to optimizing your local business for search, you know that directories play a significant role in building authority for a company. But we know you’re cooler than that. You want more from your local search optimization strategy. Why You Can’t Ignore Social Optimization You can’t afford not to create a social media strategy for three reasons: 1. [emailoptin type="social"][/emailoptin]As a rule, you should claim as many social media listings as you can now, so someone else can’t do it later. Use Knowem or Namecheck to see what you might have available. 2. We’ve said this many times before, but Google and Bing both confirm that Twitter and Facebook influence SEO. When customers search for brand names, social profiles create more opportunities for clicks and traffic because they occupy valuable space on search engine results pages. This is a personalized search result. If you don’t create and optimize these profiles, you’re leaving referral traffic (and money) on the table. 3.
