On Twitter and in the Workplace, It's Power to the Connecto by Rosabeth Moss Kanter | 1:00 PM November 16, 2009 In the World According to Twitter, giving away access to information rewards the giver by building followers. The more followers, the more information comes to the giver to distribute, which in turn builds more followers. The process cannot be commanded or controlled; followers opt in and out as they choose. The results are transparent and purely quantitative; network size is all that matters. The significance of Twitter is yet to be determined; it is a simple, impersonal, and transient application of technology. America in the 20th century was called a “society of organizations.” Today, people with power and influence derive their power from their centrality within self-organizing networks that might or might not correspond to any plan on the part of designated leaders. This changes the nature of career success. Connectors have always been more promotable, even in traditional hierarchies. To be known is to be in the know.
iPwned: How easy is it to mine Apple services, devices for data? Apple executives never mentioned the word "security" during the unveiling of the iPhone 6, iPhone 6+, and Apple Watch yesterday, choosing to focus on the sexier features of the upcoming iOS 8 and its connections to Apple's iCloud service. But digital safety is certainly on everyone's mind after the massive iCloud breach that resulted in many celebrity nude photos leaking across the Internet. While the company has promised fixes to both its mobile operating system and cloud storage service in the coming weeks, the perception of Apple's current security feels iffy at best. In light of one high profile "hack," is it fair to primarily blame Apple's current setup? In the name of security, we did a little testing using family members as guinea pigs. As things stand right now, a determined attacker will still find plenty of ways to get to iPhone data. A quick word on Apple security Again, Apple has a number of security fixes coming. iCloud busting, phase 1: With professional tools
Intelligences Multiples : présentation présentation Parmi les nombreuses grilles d'intelligences qui ont été élaborées, la théorie des Intelligences Multiples d'Howard Gardner a le mérite d'être particulièrement simple à comprendre (car parlant bien à l'intuition) et pratique à utiliser dans une quelconque situation d'apprentissage. Son succès dans le monde anglo-saxon depuis sa parution en 1983 a été considérable, en particulier dans les champs de l'éducation et de la formation permanente. Elle a fait l'objet de très nombreux livres d'application en langue anglaise. Selon Gardner, on peut distinguer huit intelligences : Les huit intelligences, selon Howard Gardner l'intelligence verbale / linguistique C'est la capacité à être sensible aux structures linguistiques sous toutes ses formes. l'intelligence visuelle / spatiale C'est la capacité à créer des images mentales, et à percevoir le monde visible avec précision dans ses trois dimensions. l'intelligence musicale / rythmique l'intelligence logique / mathématique
Why Your Friends Have More Friends Than You Do | Psychology Toda One of my all-time favorites among all the scientific papers that I have ever read in my life is “Why your friends have more friends than you do,” published in the in 1991 by my old sociology friend Scott L. Feld, who is now Professor of Sociology at Purdue University. The title of Feld’s paper says it all, and here’s a little demonstration you can do to confirm his conclusion. List all of your friends. Then ask each of your friends how many friends they have. No matter who you are, whether you are a man or a woman, where you live, how many (or few) friends you have, and who your friends are, you will very likely discover that your friends on average have more friends than you do. But how can this be? Feld demonstrates (and explains) the seeming paradox with a simple example in his paper. If you think about it for a moment, you’ll figure out the source of this seeming paradox (although this simple insight did not occur to before Feld published his paper in 1991).
Relationship Symmetry in Social Networks: Why Facebook will go F A description of symmetry and how it affects relationships in social networks. Also, a prediction that Facebook will eventually go asymmetric. Recent events have made it clear that Facebook sees Twitter as a serious threat to its business. First, Facebook tried to buy Twitter for $500,000,000 in stock. In addition, Facebook redesigned their Pages feature. This, of course, is how Twitter works. Relationship Symmetry In general, there are two ways to model human relationships in software. Facebook, on the other hand, has always used a “symmetric” model, where each time you add someone as a friend they have to add you as a friend as well. Andrew Chen recently described one advantage of the Twitter model. People who follow you, but you don’t follow backPeople who don’t follow you, but you follow themYou both follow each other (Friends!) Attention Inequality & the Power of Asymmetry As Andrew points out, an asymmetric model allows for more types of relationships. What of Other Networks?
Why I Love Twitter - O'Reilly Radar If you care what I think, you know that Twitter is just about the best way to learn what I’m paying attention to. I pass along tidbits of O’Reilly news, interesting reading from mailing lists and blogs I follow, and of course, tidbits from the twitterers I’m following. These are all the things I could never find time to put on my blog, but that I spray via email like a firehose at editors, conference planners, and researchers within O’Reilly. A lot of my job is, as we say, “redistributing the future” – following interesting people, and passing on what I learn to others. And twitter is an awesome tool for doing just that. Like a lot of people, I tried out Twitter early on, but didn’t stick to it. I thought I should outline here some of the specific things I find so compelling about Twitter, with suggestions about architectural features to be emulated by other internet services. Twitter is simple. What’s different, of course, is that Twitter isn’t just a protocol.
Joël de Rosnay: «L’homme du futur sera relié au cerveau planétaire» Le XXIe siècle n’a pas commencé en l’an 2000, cette date parfaitement artificielle, mais il commence véritablement aujourd’hui, après une petite décennie de tâtonnements d’où sont en train d’émerger les grandes tendances de fond, les vraies lignes de force du siècle à venir. Pour Joël de Rosnay, biologiste et docteur ès sciences, président de la Cité des sciences et de l’industrie à Paris, futurologue et auteur de plus d’une trentaine d’ouvrages, le monde actuel est en pleine effervescence et l’être humain à la veille d’une nouvelle aventure qui va transformer aussi bien sa conscience de soi que son rapport aux autres. Quelles vont être les grandes tendances du XXIe siècle? On assiste à la convergence de trois disciplines, l’infotechnologie, la bio-technologie et l’écotechnologie, qui se marient les unes avec les autres et créent une dynamique porteuse d’avenir. C’est ce qui donne l’impression d’être au début d’une ère nouvelle. L’homme est-il en train de changer? Il a déjà changé!
Intelligence ou intelligences Réflexion générale: « Pourquoi l'échec affecte autant l'estime de soi et pourquoi les individus ont tellement besoin de protéger leur estime de soi quand ils échouent? Intellect, beauté... Une des pistes de réflexion actuelle suppose une survalorisation de l'intelligence dans la société. Ce n'est pas parce qu'on parle bien qu'on est intelligent! I. Les modèles de l'intelligence sont basés sur les modèles cognitifs au sens large. • L'évaluation des fonctions intellectuelles repose sur une théorie de l'intelligence: - Il n'existe pas de définition abstraite de l'intelligence - L'intelligence c'est mettre en pratique des capacités adaptatives qui résultent d'aptitudes (Thurnstone) - Ces aptitudes représentent l'efficacité fonctionnelle de différents processus cognitifs (exemple: degré de perception, ou d'attention) • Les modèles classiques de l'intelligence sont donc des modèles de l'efficience intellectuelle. - Factoriels: Car ils décrivent l'intelligence comme une mosaïque d'aptitudes.

Early Tremors: Is It Time for Another Social Network Shakeout? - Faint rumblings have begun in the social networking landscape. Facebook acquired smaller rival FriendFeed in August. Friendster, viewed as an also-ran in the U.S., has refocused its operations on the Asia-Pacific region, where it is among the leaders in traffic. Social networking sites allow individuals to connect online and share content like photos and video. When Knowledge@Wharton wrote about social networking sites back in 2006, experts noted that some high-fliers may go from “hot” to “not” quickly. What’s unclear is where social networking goes from here. For instance, Facebook’s acquisition of FriendFeed revolved largely around a talent and technology grab. Indeed, experts at Wharton expect the Facebook-FriendFeed scenario to play out repeatedly in the next few years. Kendall Whitehouse, director of new media at Wharton, notes that “social networking sites are still popping up” but with questionable prospects.

Venessa: Is Twitter A Complex Adaptive System I've seen a bunch of posts bubble up over the past few days that are really sparking my curiousity about what is really going on with Twitter, so I need to do a little brain dump. Bear with me. Insight #1 An article by Rosabeth Moss Kanter was just published today on the Harvard Business Review website, titled On Twitter and in the Workplace, It's Power to the Connectors. She also points out that success today is based on a person's ability to leverage power and influence within their social networks, to act as "connectors" between people and information, and in turn build social capital. She leaves the evaluation of the significance of Twitter open-ended, but she lays out a few characteristics of Twitter that I found most interesting: In the World According to Twitter, giving away access to information rewards the giver by building followers. (just keep those points in mind, I'm going to come back to it) Insight #2 From a social viewpoint, the architecture of business seems all wrong.
L'Atelier des icônes | Le carnet de recherche d'André Gunthert Les usages ordinaires des images L’histoire de l’art comme les visual studies privilégient une approche autonomiste des images, bien loin de leurs usages réels. Utilisées comme supports de récit ou espaces de projection, les images interviennent dans la culture ordinaire de façon décorative ou utilitaire, à des fins principalement référentielles, comme des outils de transaction ou de naturalisation des formes culturelles. Seule la prise en compte de la globalité des dispositifs, des circulations intermédiales et de l’interaction avec la réception permet de comprendre les particularités et les forces des ressources visuelles. Séminaire de recherche ouvert aux doctorants et masterants, 1er et 3e jeudis du mois de 18 h à 20 h (INHA, salle Walter-Benjamin, 2 rue Vivienne, 75002 Paris), du 6 novembre 2014 au 14 mai 2015 (descriptif sur le site de l’EHESS).
