Social Network Analysis (SNA) Software with Sentinel Visualizer

Social Network Analysis (SNA) Software with Sentinel Visualizer
Degree Centrality Degree centrality is simply the number of direct relationships that an entity has. An entity with high degree centrality: Is generally an active player in the network. Is often a connector or hub in the network. Is not necessarily the most connected entity in the network (an entity may have a large number of relationships, the majority of which point to low-level entities). In our example network diagram above, Alice has the highest degree centrality, which means that she is quite active in the network. Betweenness Centrality Betweenness centrality identifies an entity's position within a network in terms of its ability to make connections to other pairs or groups in a network. Holds a favored or powerful position in the network. In the example above, Rafael has the highest betweenness because he is between Alice and Aldo, who are between other entities. Closeness Closeness centrality measures how quickly an entity can access more entities in a network. Eigenvalue Related:  Recursos Pedagógicosjour 01

Site monta mapa-múndi das mídias sociais. Confira E se cada mídia social fosse um país, como seria o mundo? Pelo menos do ponto de vista geográfico, é possível ter ideia de como isso seria. É que o site Flowtown (www.flowtown.com) montou uma espécie de mapa-múndi onde cada rede aparece como um país, ocupando um espaço proporcional ao número de usuários que tem. Soberano, o Facebook aparece com o maior território, fazendo fronteira – ao sul – com o Twitter. Junto ao nome das maiores redes, o mapa indica a "população" do território. A Google aparece no mapa ocupando todo o espaço do Pólo Sul, indicado como império. Wiki Ilhas

January « 2009 « Scientometrics, Knowledge Management, and Social Network Analysis Library System I have been looking for a simple library management system recently. Some popular proprietary system: by SirsiDynix (Dynix, Horizon, Symphony, Unicorn) and by Innovative Interfaces (Millenium). Some popular Open Source Integrated Library System: Koha and Evergreen. One library management system (for a small one) and if you don’t need it to work as an OPAC/Online Public Access Catalogue is BookDB2. It’s a stand-alone program which is suitable for your home library. Corporate Connections I’ve seen this diagram before, but was reminded again of it through digg today.

50+ Social Bookmarking Sites : Importance of User Generated Tags, Votes and Links Editor’s Note: This post was updated in October of 2016. Is social bookmarking still relevant in 2016? Read this updated post by Anna Crowe to learn more. The positive effects of social bookmarking for publishers of news sites, blogs, and other websites are outstanding. Social bookmarking can introduce sites to others with relevant tastes and drive traffic and valuable backlinks to your site. Some social bookmark sites pass on link juice, while some use the NoFollow attribute. The Benefits of Social Bookmarking The external metadata compiled via user-generated descriptions, tags, titles and categorization is incredibly valuable to search engines, as in the same philosophy as anchored backlinks, descriptive content about a web site defined by the users of that site who are not associated with the marketing or coding of that site, can be extremely powerful in gauging the importance and relevance of the content and tags which are used on that site.

Learn how to read music | Jayde Musica | Music Theory Game Bookmarks: Soon Obsolete? - PCWorld Since the Web first came online in 1991, it has grown and improved beyond anyone's predictions. Unlike the gray background, mono-spaced text and ugly graphics on the Web in those early years, today's Web is rich with video, interactive applications and other useful and distracting goodies. But even after all these years, the way we find, navigate and save content on the Web works pretty much like it always did. Here's a page with text. Some of the words are hyperlinked, so when you click on them, you open another page. If you want to save something, there's a wide variety of tools that help you do so, but most people use the bookmarking feature built into their browsers, or social bookmarking sites. But now there's a conspicuously innovative new option. The service is functionally similar in some ways to social bookmarking sites, but its core function is "curation," which Wikipedia defines as the "selection, preservation, maintenance, and collection and archiving of digital assets."

Rob Cross Introduction to Organizational Network Analysis Over the past decade or so significant restructuring efforts have resulted in organizations with fewer hierarchical levels and more permeable functional and organizational boundaries. While hopefully promoting efficiency and flexibility, a byproduct of these restructuring efforts is that coordination and work increasingly occur through informal networks of relationships rather than through formal reporting structures or prescribed work processes. These seemingly invisible webs have become central to performance and strategy execution. Research shows that appropriate connectivity in networks within organizations can have a substantial impact on performance, learning, and innovation, and benefits also accrue from well-connected networks between organizations. Three important points quickly emerged from the ONA: First, the ONA identified mid-level managers that were critical in terms of information flow within the group. Lines and Arrows.

The Instagram accounts changing the world No one can really dispute the power of social media. Whether it's raising awareness for once-ignored issues, or helping to bring down entire governments, sites like Facebook, Twitter and Instagram are now stronger than ever. Offering people the chance to take pressing political problems into their own hands, it's become a whole new way of addressing everyday social injustice. “Instagram has a way of uniting complete strangers in a way that Facebook, for example, does not,” explains Amber Amour, founder of #StopRapeEducate. “It's a useful tool because it allows one to reach a large audience, and to be heard.” With their slogan emblazoned across the chests of basically everyone – from Cara Delevingne to Miley Cyrus – the notorious Free The Nipple movement has had no shortage of publicity recently. Born out of desperation and despondency, Amber Amour started the #StopRapeEducate campaign after she was sexually assaulted by her roommate last year.

Parece Facebook, mas não é: são as redes educativas - Educação Internet Serviços ganham força nos Estados Unidos e desembarcam no Brasil. Professores e alunos podem fazer quase tudo ali, desde que seja educativo Nathalia Goulart Edmodo: rede social voltada para professores e alunos tem quase 10 milhões de usuários (Reprodução) Seus usuários trocam mensagens, compartilham fotos e comentam atividades recentes. Leia também:Conheça seis redes sociais voltadas à educação No Facebook, estudante de 13 anos narra rotina de problemas de escola pública Por enquanto, uma das poucas redes internacionais que disponibilizam conteúdo em português é a Edmodo, sucesso nos Estados Unidos. O funcionamento da Edmodo, da Teamie e dos demais serviços nascentes é bastante parecido. A bem-sucedida experiência internacional da Edmodo entusiasmou o professor de história Rodrigo Abrantes, do Colégio Joana D'Arc, de São Paulo.

Dossier > L'infini est-il paradoxal en mathématiques ? Jean-PaulDelahaye Mathématicien Informaticien Pour résoudre le paradoxe du tout et des parties et affronter l’hypothèse du continu, notre idée de l’infini actuel doit évoluer ; aujourd’hui encore, nous découvrons de nouveaux infinis. L’infini mathématique peut-il être maîtrisé ? Un paradoxe au sein d’une théorie est la possibilité de démontrer une chose et son contraire. Le paradoxe de l’hôtel de Hilbert (à découvrir à la page suivante) montre pourquoi des ensembles infinis ont longtemps paru absurdes. © Belin Aujourd’hui, les mathématiciens connaissent toutes sortes de moyens pour contourner les paradoxes au sein des théories mathématiques de l’infini. Une situation logiquement insatisfaisante apparaît lorsqu’une théorie nous permet d’énoncer des propriétés étonnantes, parfois opposées à notre attente, sans toutefois qu’une véritable contradiction apparaisse. Quelques exemples pour illustrer la réflexivité, sur laquelle Cantor a notamment travaillé. © Belin

How Instagram is breeding a new generation of idols We all know that feeling – scrolling endlessly on social media and in rolls the perfect picture to summarise exactly how you’re feeling. Most of the time our "OMG, this is so me!” moments are more likely to be videos of cute pugs on hung-over Monday mornings or The Simple Life screen grabs, as opposed to life affirming art. Now a group of young creatives are seeking to intellectualise this insta-slang with new group show Same, curated by reigning royalty of the Internet, Molly Soda. Digital artist Soda found herself increasingly fascinated by this phenomenon, “I love that people can feel so connected to images that aren’t their own,” Soda explains. “It’s almost comforting in a way, to know that we have the ability to feel connected to complete strangers.” Unlike celebrities, whose actual contact with their social media platforms is often minimal, artists working online have full access to how people react to their work.

Create Video Notebook: Dan Roam and The Back of the Napkin Doing this blog is like standing in the library with thousands of books and resources. I get overwhelmed at the talent and creativity that surrounds us. I also get angry at what we choose to pay attention to but that is another story. I need to learn to tell visual non-fiction stories using video. Dan Roam and his book The Back of the Napkin is helping me learn that skill. Dan coaches business leaders to use visuals to explain concepts. I'm going to buy his book this weekend. Here is an example made for BNet.com on Visual Thinking. You don't need an MBA to understand what he is talking about. It was painless. Definitely visit this site and check out his blog as well.

La fascinante nouvelle carte 3D animée de l’univers observable (Vidéo) | GuruMeditationGuruMeditation Une équipe internationale de chercheurs a mis en place une extraordinaire carte vidéo 3D de l’univers proche avec une profondeur de 300 millions d’années-lumière. La vidéo est un rappel, qui n’est pas si subtil, de la façon dont nous sommes ridiculement minuscules et encore, ce n’est que la partie visible de l’univers, une infime partie de celui-ci… Ci-dessous, comme pour l’animation d’entête, une carte montrant toutes les galaxies dans l’univers proche. Chaque galaxie dispose d’un code couleur pour indiquer sa distance, du bleu pour les plus proches et rouge pour les plus éloignées, jusqu’à 300 millions d’années-lumière. Ce travail fait partie d’un projet appelé Cosmic Flows (flux cosmique) et il consiste à cartographier la densité de la matière à la fois visible et noire autour de notre galaxie, jusqu’à une distance de 300 millions d’années-lumière. La vidéo dure plus de 17 minutes, mais que cela ne vous rebute pas. Pour Hélène Courtois, dans la vidéo :

Estudo nega que redes sociais criem 'bolha ideológica' Pesquisa mostra que Facebook não priva usuários de conteúdos contrários à sua ideologia (Foto: Reprodução) Redes sociais como o Facebook não estão colocando os usuários em uma "bolha ideológica" de informações, apesar dos temores pelo contrário, revelou uma pesquisa divulgada nesta quinta-feira (7). O estudo publicado pela revista "Science", baseado em uma análise de 10 milhões de usuários do Facebook e sete milhões de links da internet, encontrou que muitas das histórias compartilhadas na rede social permitiram que as pessoas obtivessem pontos de vista diferentes dos seus. Os resultados minimizam as preocupações de alguns setores com o fato de que as redes sociais estariam levando à polarização política ao agrupar as pessoas ao longo de linhas ideológicas e não expô-las a pontos de vista opostos. O Facebook tem estado na mira dos pesquisadores porque usa algoritmos que visam oferecer histórias relevantes para cada usuário com base em seus interesses.
