How can you determine the health of a community?

A lot of community managers just go with their gut on this one, or use proxy metrics like signups, posts per day, klout scores, retweets or some other metric that is fairly hollow, but there are better ways.

This is very much a work in progress, so I’d love to collaborate. If anyone has any thoughts, please jump in the comments sections and let’s discuss. That being said, most of this isn’t new, it’s just stolen, adapted and generally simplified from concepts like Network Theory, Affinity Groups, Clustering Coefficients, Small World Networks, and other things I will never fully understand or convince people to invest tech into.

Let’s dig in…

What is Network Density?

First off, Network Density (ND for short) isn’t one number, it’s more like blood pressure where they say “80 over 120″. I have no idea what the 80 or the 120 mean, but it works as an analogy. So, with that in mind, ND breaks down roughly as:

Average Distance Between Users : Number of Paths : Frequency of Interactions

or simply put…

AD : NP : F

Lets break each part down…

David McCandless : « L’interaction est le futur de la datavisualisation »

David McCandless : « L’interaction est le futur de la datavisualisation » | e-Xploration | Scoop.it

David McCandless, précurseur du design d’information, a donné une conférence à Paris dans le cadre des Rencontres RSLN aux Techdays. Après un entretien sur les définitions du design d’information, Claire et Camille reviennent sur ce qu’il faut retenir de ce rendez-vous entre McCandless et son public.

Cas pratiques

Pour nous plonger au cœur de son monde, McCandless a ponctué son intervention de cas pratiques. Les données sont partout et racontent des histoires. La magie, point de départ de son travail – et de la présentation – se base sur cette supposition : « Quelque chose de magique peut se passer ».

La datavisualisation doit révéler une information intéressante qui permet de créer un lien avec le lecteur. Mais elle doit aussi être belle et attractive pour acquérir la confiance du lecteur. Premier exemple d’illustration du pouvoir d’une visualisation de données ? Les dettes d’état. Le journaliste explique :

« Les chiffres sont partout dans la presse, mais on ne les comprend pas vraiment. C’était une sorte de frustration alors j’ai décidé de les mettre en forme en utilisant des couleurs. Cette mise en forme permet de révéler des modèles et des tendances et de faire ressortir les chiffres marquants. On a une relation différente avec les chiffres et on peut voir les choses instantanément. »

Les données permettent également de mettre en valeur ce qui se passe dans l’imaginaire collectif. Comme l’explique McCandless :

« Les données permettent de voir l’invisible. Des choses qui n’apparaissent que quand on les regroupe et que l’on peut facilement intégrer par les yeux. On compresse les données pour qu’elles soient compréhensibles.»

Les craintes provoquées par les jeux vidéo font ainsi toujours suite à des évènements dramatiques : en 1999, avril et mai ont connu des pics d’appréhensions. L’explication pour le journaliste ? Elles faisaient suite à la fusillade de Columbine. Et on a pu observer la même chose sur la peur après les attentats du 11 septembre.

Dans un registre plus léger et jour de Saint-Valentin oblige, « le pape de la data-visualisation » n’a pas manqué de revenir sur les tendances « data » concernant les couples en révélant une infographie sur les périodes de ruptures amoureuses les plus communes dont les pics se situent habituellement un peu avant Pâques et Noël.

Via Ides De Vos, A. J. Alvarez-Socorro
luiy's insight:

The mainstream ways of thinking about management are based on the sciences of certainty. The whole system of strategic choice, goal setting and choosing actions to reach the given goals in a controlled way depends on predictability. The problem is that this familiar causal foundation cannot explain the reality we face. Almost daily, we experience the inability of people to choose what happens in their organizations – or in their countries. We live in a complex world. Things may appear orderly over time, but are inherently unpredictable.

 

Complexity refers to a pattern, a movement in time that is at the same time predictable and unpredictable, knowable and unknowable. Healthy, ordinary, everyday life is always complex, no matter what the situation is. There is absolutely no linearity in the world of human beings.

Human patterns that lose this complexity become repetitive and rapidly inappropriate for dealing with life. Unlike mechanical systems, human systems thrive on variety and diversity. An exact replication of behavior in nature would be disastrous and seen as neurotic in social life. For example, a failing heart is typically characterized by increasing loss of complexity.


A pattern is something that emerges through the complex interactions between elements in a system. Although there is apparent order, there is never exact repetition if the system is viable. This is why human interaction cannot be understood as processes in the way they were used in manufacturing, but as patterns.

 

Patterns that are more repetitive are normally called routines or habits. This conclusion is important for us. Novelty emerges in a radically unpredictable way. Creativity is seldom the end result of a repetitive process.

Ides De Vos's curator insight, March 13, 2013 12:52 PM

In our lineair thinking , we think that everything has a solution .We are certain of that ...but we know that in real life , there is no one solution because the results of interaction between human beings is unpredictable .

So the only certainty we have is uncertainty

Neural networks have received a lot of attention for their abilities to ‘learn’ relationships among variables.

Via Scott Turner
luiy's insight:

Neural networks have received a lot of attention for their abilities to ‘learn’ relationships among variables. They represent an innovative technique for model fitting that doesn’t rely on conventional assumptions necessary for standard models and they can also quite effectively handle multivariate response data. A neural network model is very similar to a non-linear regression model, with the exception that the former can handle an incredibly large amount of model parameters. For this reason, neural network models are said to have the ability to approximate any continuous function.

 

I’ve been dabbling with neural network models for my ‘research’ over the last few months. I’ll admit that I was drawn to the approach given the incredible amount of hype and statistical voodoo that is attributed to these models. After working with neural networks, I’ve found that they are often no better, and in some cases much worse, than standard statistical techniques for predicting relationships among variables. Regardless, the foundational theory of neural networks is pretty interesting, especially when you consider how computer science and informatics has improved our ability to create useful models.

Complex Adaptive Systems Modeling | Full text | PyCX: a Python-based simulation code repository for complex systems education


Via Hiroki Sayama
luiy's insight:
Abstract

We introduce PyCX, an online repository of simple, crude, easy-to-understand sample codes for various complex systems simulation, including iterative maps, cellular automata, dynamical networks and agent-based models. All the sample codes were written in plain Python, a general-purpose programming language widely used in industry as well as in academia, so that students can gain practical skills for both complex systems simulation and computer programming simultaneously. The core philosophy of PyCX is on the simplicity, readability, generalizability and pedagogical values of simulation codes. PyCX has been used in instructions of complex systems modeling at several places with successful outcomes.

Industrializing Personal Data Production (First Monday)


Via Pierre Levy
luiy's insight:

Free trade and free speech: the Internet ideal

Facebook text didn’t just arrive on our screens; rather, it echoes key discourses embedded in abstractions offered by other monopoly new media dominating our desktops. It developed, built upon and extended a set of pre–existing structures hardcoded in online globally consumed interfaces, referred to here as “the Web’s commercial interface” (Patelis, 2010). The Web’s commercial interface, of which Facebook is now an integral part, lies at centre stage of the online of experience of a majority of users in the West. Its properties cannot be exhausted within the confines of this paper.

Instead we wish to focus on a key component crucial to Facebook: the integration of commerce and communication. The Internet mediates the integration of commerce and communication, unifying and demanding the synchronous development and integration of very dissimilar services and by extension objects. In other words, at the heart of text offered by monopoly new media software, lies the liberal ideal according to which commerce and communication can and should be integrated online, the idea that free speech and free trade are two sides of the same coin and that, by extension, online commerce and online communication are complementary ideals in the democratic capitalist ideal. In representational terms, such integration is so naturalised that a kilo of potatoes for sale and an opinion on paedophilia are literally represented as similar objects across outlets. To quote Bill Gates from 1996:

 

“Capitalism, demonstrably the greatest of the constructed economic systems, has in the past decade clearly proved its advantages over the alternative systems, As the Internet evolves into its broadband, global interactive network, those advantages will be magnified. Product and service providers will see what buyers want a lot more efficiently than ever before and consumers will buy more efficiently. I think Adam Smith would be pleased.” [2]

 

We argue that Facebook has been central to the further restructuring and commodification of the media industry around this ideal by establishing further integration of commerce and communication in two ways. Firstly, through the demonization of anonymity and secondly, through the industrialisation of the production of personal data. Coupled with Facebook’s endeavour to colonise the Web, this restructuring has taken centre stage in the development of the media industry recently. Facebook text is key to understanding the broader standardization process of communication on the Web, mainly because it demands user participation in the production process and naturalizes the commodification and industrialisation of personal data. Personalization is a large part of communication in Facebook to the point that personalization — and hence standardization — constitute the product. Thus, individualized information is less important than the fact that information will be archived and ‘pprocessed’, with more personal data produced as a result. This processing allows Facebook to industrialise the production of data.

Pierre Levy's curator insight, March 12, 2013 1:13 PM

This article examines Facebook.com as a cultural text. It casts a critical eye on the stories told by the Facebook monopoly interphase, focusing on how these intergrate commerce with communications. It struggles with the text’s key abstractions arguing that Facebook industrialises personalised data production by demanding the constant production on customised communcation objects.

InternetActu.net est un site d'actualité consacré aux enjeux de l'internet, aux usages innovants qu'il permet et aux recherches qui en découlent.
luiy's insight:

L’après-midi de la journée d’études PraTic a continué (voir la première partie) avec une intervention passionnante de Paul Edwards, professeur de sciences de l’information et d’histoire à l’université du Michigan, qui s’est penché sur les aspects “matériels” de la collection de données, ce qu’il appelle la “friction des données”. Car celles-ci impliquent un coût en transport, en énergie, qui peut ralentir l’analyse. Il rappelle que dans les années 50, le nombre de cartes perforées au centre de données météorologiques américain était si important qu’on croyait que le bâtiment risquait de s’effondrer sous le poids !

A cette friction des données correspond celle des “métadonnées”, qui racontent comment les données ont été construites. Paul Edwards a illustré le problème à partir d’exemples sur le réchauffement climatique (comme il l’a fait dernièrement dans l’émission Place de la Toile où il évoquait le même thème).

Lorsqu’on travaille dans ce domaine, on cherche à transformer les informations météo, issues du court terme, en tendances climatiques, propres au long terme. Dans ce cas, il importe parfois de savoir comment ont été collectées les données de base, si la station météo à l’origine des observations a subi des changements, comment on a calculé les moyennes, etc. Il existe en effet des centaines de manières de calculer une moyenne journalière. Les différences obtenues sont minimes, mais elles existent. Si on connait le mode de calcul, on peut procéder à des ajustements, si on l’ignore cela peut engendrer des erreurs. Par exemple, des cartes de pluviométrie en Finlande ont connu un changement de l’ordre de 20% parce qu’on avait modifié les horaires d’observation des stations météo.

Agent-Based Models and Systems Science Approaches to Public Health

Agent-Based Models and Systems Science Approaches to Public Health http://t.co/7mkf4MJfVB #hcsim
luiy's insight:

The utility of any model is that it can represent complex processes in a simplified form to enhance understanding. Models permit experimentation in a virtual environment. For ABMs, aspects of the real world are represented in a computer program as “agents”, which follow simple behavioral rules. Such models are based on what is known (or assumed) about individual behavior, and population-level behavior emerges given various starting conditions.

 

In this issue of AJPM, Yang et al.1 use an ABM to explore walking behavior in a community. Low levels of physical activity are associated with increased health risks, and so interventions to increase physical activity are likely to confer health benefits. But exactly which interventions will have substantial effects at the population level is not well understood. Here, walking behavior was simplified in an agent-based model in which each agent was assigned a probability of walking or not walking for leisure, errands, or commuting. The model was used to explore how land use and safety issues might affect walking behavior, thus informing intervention development.

 

Also in this issue, Auchincloss et al.2 use an ABM to explore the impact of food preferences and prices on dietary disparity related to income, demonstrating that to overcome observed patterns of income-related dietary disparity, both preferences for healthy food and availability of cheap healthy food are necessary. Their model helps tease out the social determinants of health in a situation in which empirical data are lacking.

 

Just as models and simulations have been used to understand specific health-related issues such as disease progression,18 systems science methods show great promise for exploring policy options prior to enacting them, and for understanding how policies might be designed to work synergistically together.19Modeling and simulation have been used to address broad health issues, including optimizing vaccination policies20 and managing national healthcare policy.21

 

The next steps in modeling and simulation are to draw on evidence from specific disciplines to build models that help us see a more comprehensive picture of the interactions among the disparate systems that create overall health. It seems clear to us that ABMs—and modeling, simulation, and systems science methods more generally—can be used effectively to improve public health.

On the notion of balance in social network analysis


Via ukituki

ukituki's curator insight, December 25, 2012 5:12 PM
The notion of "balance" is fundamental for sociologists who study social networks. In formal mathematical terms, it concerns the distribution of triad configurations in actual networks compared to random networks of the same edge density.

 

On reading Charles Kadushin's recent book "Understanding Social Networks", we were struck by the amount of confusion in the presentation of this concept in the early sections of the book. This confusion seems to lie behind his flawed analysis of a classical empirical data set, namely the karate club graph of Zachary. Our goal here is twofold. Firstly, we present the notion of balance in terms which are logically consistent, but also consistent with the way sociologists use the term.

 

The main message is that the notion can only be meaningfully applied to undirected graphs. Secondly, we correct the analysis of triads in the karate club graph. This results in the interesting observation that the graph is, in a precise sense, quite "unbalanced". We show that this lack of balance is characteristic of a wide class of starlike-graphs, and discuss possible sociological interpretations of this fact, which may be useful in many other situations.

In a sense, it’s a generational thing. In 1980, the writer Bruce Bethke – whose short story “Cyberpunk” inadvertently christened the genre – was working at a Radio Shack in Wisconsin, selling TRS-80 microcomputers. One day, a group of teenagers waltzed in and hacked one of the store machines, and Bethke, who’d imagined himself a tech wiz, couldn’t figure out how to fix it. It was after this incident that he realized something: these teenaged hackers were going to sire kids of their own someday, and those kids were going to have a technological fluency that he could only guess at. They, he writes, were going to truly “speak computer.” And, like teenagers of any era, they were going to be selfish, morally vacuous, and cynical.

Chomsky: The Corporate Assault on Public Education
Our kids are being prepared for passive obedience, not creative, independent lives.
March 8, 2013  |  
 

The following is Part II of the transcript of a speech Noam Chomsky delivered in February on "The Common Good." Click here to read Part I.



Let’s turn to the assault on education, one element of the general elite reaction to the civilizing effect of the ‘60s. On the right side of the political spectrum, one striking illustration is an influential memorandum written by Lewis Powell, a corporate lawyer working for the tobacco industry, later appointed to the Supreme Court by Richard Nixon. At the other end of the narrow spectrum, there was an important study by the Trilateral Commission, liberal internationalists from the three major state capitalist industrial systems: the US, Europe and Japan. Both provide good insight into why the assault targets the educational system.


Let's start with the Powell memorandum. Its title is, “The Attack on the American Free-Enterprise System." It is interesting not only for the content, but also for the paranoid tone. For those who take for granted the right to rule, anything that gets out of control means that the world is coming to an end, like a spoiled three-year-old. So the rhetoric tends to be inflated and paranoid.

Après la communication de Dominique Cardon sur “les sociabilités numériques” puis celle de Thierry Baccino sur “la lecture numérique”, je ne saurais trop vous recommander d’écouter l’intervention de Pierre Mounier*, que nous avons eu le plaisir d’accueillir, le 29 novembre dernier, à la Médiathèque de Miramas. Cette communication a pour titre “La culture est-elle soluble dans l’e-book? Les enjeux de la métamorphose du livre à l’ère numérique”.En voici le contenu synthétique :

“Presque 600 ans après l’invention de l’imprimerie, le livre connaît une nouvelle révolution technologique en se dématérialisant au sein des réseaux numériques. La montée en puissance des “liseuses” et “tablettes multimédia” annonce un tournant majeur dans l’histoire du livre. L’horizon est aujourd’hui un peu obscurci par, d’un côté les slogans marketing qui mettent en avant les avantages pratiques des nouvelles machines, et de l’autre les crispations luddites autour de la “sensualité du livre” et de l’“odeur du papier”. Pourtant, cette métamorphose du livre numérique porte d’autres enjeux, éminemment politiques. Car si le livre est un produit marchand, fruit d’une industrie spécialisée, il est aussi, et peut-être d’abord un vecteur privilégié de partage des savoirs et de l’expression artistique ; en un mot de la culture. Cette tension de l’économie et de la culture, cristallisée sous le terme problématique d’“industrie culturelle” est réactivée à l’occasion du passage du livre au numérique. Et c’est bien à la lumière de cette question qu’il faut décrypter tous les débats autour du prix du livre et de son mode de distribution, du “piratage” (ou partage ?) des œuvres, du rôle des acteurs traditionnels (éditeurs, libraires, bibliothèques) mais aussi nouveaux (moteurs de recherche, médias sociaux) de la chaîne du livre, de l’évolution des usages de lecture, et jusqu’aux formats d’encodage des ouvrages.”

"Twitter Revolution" is the unfortunate generalization foisted on the world by headline writers. The realities of social upheavals and political revolutions is more complex than that, and while sociologists such as Zynep Tufekci are sorting out the complex role of social media in physical world events, others are documenting the role of social-media in post-revolutionary societies.

Analytics for Twitter allows users to query Twitter directly in Microsoft® Office Excel 2010.

 

Weer een tool via Twittermania gevonden die wel enigszins voorbereidend werk kost. Je hebt nodig Excel 2010 en een programma Powerpivot, maar dan heb je ook wat! Een middel om alle data in te voeren, zoals twitternamen en #hashtags. Je krijgt veel informatie mooi weergegeven in duidelijke grafieken!

When it comes to creating graphics for visual social networks, there are a few key ideas you should keep in mind to increase your reach and engagement. Your audience wants to be educated. They want to be inspired.

 

Of course, depending on the network in which you are promoting your content, the visual itself may be the entire piece of content, thus making it equally as important as the content it contains.

While all three allow for the option to link to more information in the comments, caption or description sections, the visual is the content for all intents and purposes since you can’t depend on someone clicking for more information.
