Ralph Waldo Emerson never said “Build a better mousetrap, and the world will beat a path to your door.” The mousetrap that likely inspired the misquote was invented seven years after his death. Unfortunately, many people take it literally. GHPs have all the hallmarks of a better mousetra

The ethics of unintended consequences

The ethics of unintended consequences | Sustainable Futures | Scoop.it

In a complex adaptive system we have dispositionality not causality, so when we act we cannot know what will happen.  That means we need to maintain the ability to respond quickly, something I brought in at the end when I talked about complexity approaches to project management.

Determinants of Meme Popularity

Online social media have greatly affected the way in which we communicate with each other. However, little is known about what are the fundamental mechanisms driving dynamical information flow in online social systems. Here, we introduce a generative model for online sharing behavior and analytically show, using techniques from mathematical population genetics, that competition between memes for the limited resource of user attention leads to a type of self-organized criticality, with heavy-tailed distributions of meme popularity: a few memes "go viral" but the majority become only moderately popular. The time-dependent solutions of the model are shown to fit empirical micro-blogging data on hashtag usage, and to predict novel scaling features of the data. The presented framework, in contrast to purely empirical studies or simulation-based models, clearly distinguishes the roles of two distinct factors affecting meme popularity: the memory time of users and the connectivity structure of the social network.

luiy's curator insight, January 30, 3:30 AM

In summary, despite its simplicity, the model matches the empirical popularity distribution of hashtags on Twitter remarkably well; this is consistent with random-copying models of human decision-making [28] where the quality of the product—here, the “interestingness” of the meme—is less important than the social influence of peers’ decisions[29]. The generalization of the model (as shown in the SM) to incorporate (i) heterogeneous user activity rates and (ii) a joint distribution p jk of the number of users followed j and the number of followers k, remains analytically tractable and confirms the robustness of our main finding: that competition between memes for the limited resource of user attention induces criticality in the vanis hing-innovation limit, giving power-law popularity distributions and epochs of linear-in-time popularity growth. We believe that theanalytical results and potential for fast fitting to data will render this a useful null model for further investigations of the entangled effects of memory, network structure, and competition on information spread through social networks [30].

Angry Bear » Inequalities, National and Global

The publication of Thomas Piketty’s Capital in the Twenty-First Century brought attention to an issue that has been slowly seeping into public discourse. President Obama’s State of the Union address made it clear that we will not need to wait until the 2016 Presidential campaign to hear proposals to rectify the rise in inequality. But the data and trends of global inequality reveal a more complex situation than the national states of affairs that Piketty highlights.
