Evolution Researchers have long assumed that factors like competition, environmental change and competition for scarce resources stimulated evolutionary change in species. But computer science... [[ This is a content summary only.
We show that the resolution of social dilemmas on random graphs and scale-free networks is facilitated by imitating not the strategy of better performing players but rather their emotions. We assume sympathy and envy as the two emotions that determine the strategy of each player by any given interaction, and we define them as probabilities to cooperate with players having a lower and higher payoff, respectively. Starting with a population where all possible combinations of the two emotions are available, the evolutionary process leads to a spontaneous fixation to a single emotional profile that is eventually adopted by all players. However, this emotional profile depends not only on the payoffs but also on the heterogeneity of the interaction network. Homogeneous networks, such as lattices and regular random graphs, lead to fixations that are characterized by high sympathy and high envy, while heterogeneous networks lead to low or modest sympathy but also low envy. Our results thus suggest that public emotions and the propensity to cooperate at large depend, and are in fact determined by the properties of the interaction network.
Evolution of emotions on networks leads to the evolution of cooperation in social dilemmas

Supporting a new strategy development is nothing special. But how to make sure its adequately inclusive? And what would adequately mean? I have been asked to help a company’s senior leadership to r...
Jesse Soininen's insight:
"Listening as one of the ways we attend to the whole, requires admitting that we all construct our world through self-designed lenses. By doing so, we participate in creating the very world we seem to observe only as a given. Conscious communication processes that foster inclusion enable this process of co-creation to become transparent, and in this very process, mutual understanding and respect increase."
"Two years after the Arab Spring, questions still remain as to how much social media actually helped fuel and drive the uprisings that arose in Tunisia and swept across the region. But regardless of what happened during those Twitter-fueled revolutions, what's happened afterward?
That's what social media analytics firm Crimson Hexagon and Sanitas International wanted to find out when it decided to analyze tweets coming out of Egypt, Libya and even Syria, where there still is a war going on. The results of its 3-month study, which will be discussed in a panel at SXSW on Sunday, underscore the changes these countries are undergoing."
CISCO jumps in with both feet into the Internet of Things with a new marketing campaign. In a clever move, they have taken ownership of a new phase "The Internet of Everything" worthy of its own acronym (IoE). A large press and advertising push is going out now to connect businesses with a specialist who can "ensure you are prepared."
The eye and brain: standard thinking is that these devices are both complex and functional. They are complex in the sense of having many different types of parts, and functional in the sense of having capacities that promote survival and reproduction. Standard thinking says that the evolution of complex functionality proceeds by the addition of new parts, and that this build-up of complexity is driven by selection, by the functional advantages of complex design. The standard thinking could be right, even in general. But alternatives have not been much discussed or investigated, and the possibility remains open that other routes may not only exist but may be the norm. Our purpose here is to introduce a new route to functional complexity, a route in which complexity starts high, rising perhaps on account of the spontaneous tendency for parts to differentiate. Then, driven by selection for effective and efficient function, complexity decreases over time. Eventually, the result is a system that is highly functional and retains considerable residual complexity, enough to impress us. We try to raise this alternative route to the level of plausibility as a general mechanism in evolution by describing two cases, one from a computational model and one from the history of life.

Networking is a key skill in professional careers, supporting the individual’s growth and learning. However, little is known about how professionals intentionally manage the connections in their personal networks and which factors influence their decisions in connecting with others for the purpose of learning. In this article, we present a model of personal professional networking for creating a personal learning network, based on an investigation through a literature study, semi–structured interviews and a survey.
