Both information and social cohesion determine collective decisions in animal groups

During consensus decision making, individuals in groups balance personal information (based on their own past experiences) with social information (based on the behavior of other individuals), allowing the group to reach a single collective choice. Previous studies of consensus decision making processes have focused on the informational aspects of behavioral choice, assuming that individuals make choices based solely on their likelihood of being beneficial (e.g., rewarded). However, decisions by both humans and nonhuman animals systematically violate such expectations. Furthermore, the typical experimental paradigm of assessing binary decisions, those between two mutually exclusive options, confounds two aspects common to most group decisions: minimizing uncertainty (through the use of personal and social information) and maintaining group cohesion (for example, to reduce predation risk). Here we experimentally disassociate cohesion-based decisions from information-based decisions using a three-choice paradigm and demonstrate that both factors are crucial to understanding the collective decision making of schooling fish.

Controlling collective dynamics in complex, minority-game resource-allocation systems

Resource allocation takes place in various kinds of real-world complex systems, such as the traffic systems, social services institutions or organizations, or even the ecosystems. The fundamental principle underlying complex resource-allocation dynamics is Boolean interactions associated with minority games, as resources are generally limited and agents tend to choose the least used resource based on available information. A common but harmful dynamical behavior in resource-allocation systems is herding, where there are time intervals during which a large majority of the agents compete for a few resources, leaving many other resources unused. Ac- companying the herd behavior is thus strong fluctuations with time in the number of resources being used. In this paper, we articulate and establish that an intuitive control strategy, namely pinning control, is effective at harnessing the herding dynamics. In particular, by fixing the choices of resources for a few agents while leaving majority of the agents free, herding can be eliminated completely. Our investigation is systematic in that we consider random and targeted pinning and a variety of network topologies, and we carry out a comprehensive analysis in the framework of mean-field theory to understand the working of control. The basic philosophy is then that, when a few agents waive their freedom to choose resources by receiving sufficient incentives, majority of the agents benefit in that they will make fair, efficient, and effective use of the available resources. Our work represents a basic and general framework to address the fundamental issue of fluctuations in complex dynamical systems with significant applications to social, economical and political systems.

This is definitely a major role for a community manager which is why I love learning about these two topics: community management and curation.  They are inseparable.  I think this is what makes the difference between a community that has members and a community that has ACTIVE members, which, of course, is the POINT!  Enjoy!

The Global Workforce Crisis: $10 Trillion at Risk

The Global Workforce Crisis: $10 Trillion at Risk | Content in Context | Scoop.it
Over the past few years, BCG examined workforce supply-and-demand dynamics in 25 major economies (including the G20) through 2030.1 Today, these countries collectively account for more than 2 billion economically active people, or around 65 percent of the world’s population—and more than 80 percent of total world GDP. This report highlights the impending labor shortages and surpluses and their implications for future growth. Trends across the 25 economies we studied are alarming: an equilibrium in supply and demand is rapidly becoming the exception, not the norm. Between 2020 and 2030, we project significant worldwide labor-force imbalances—shortfalls, in particular. One significant implication is the potential aggregate value of GDP squandered, because either these nations cannot fill the jobs available or they cannot create enough jobs for the workers they have. This represents a stunning $10 trillion—around 60 percent of U.S. GDP and more than 10 percent of total world GDP (according to the latest available 2013 figures). This report, the first of a series on this topic, summarizes the findings of The Boston Consulting Group’s extensive research on global talent risk and outlines basic solutions to mitigate these imbalances. The series as a whole will describe the consequences of labor imbalances for businesses and governments and offer further remedies to help mitigate them.

Symbolic regression of generative network models

Symbolic regression of generative network models | Content in Context | Scoop.it
Networks are a powerful abstraction with applicability to a variety of scientific fields. Models explaining their morphology and growth processes permit a wide range of phenomena to be more systematically analysed and understood. At the same time, creating such models is often challenging and requires insights that may be counter-intuitive. Yet there currently exists no general method to arrive at better models. We have developed an approach to automatically detect realistic decentralised network growth models from empirical data, employing a machine learning technique inspired by natural selection and defining a unified formalism to describe such models as computer programs. As the proposed method is completely general and does not assume any pre-existing models, it can be applied “out of the box” to any given network. To validate our approach empirically, we systematically rediscover pre-defined growth laws underlying several canonical network generation models and credible laws for diverse real-world networks. We were able to find programs that are simple enough to lead to an actual understanding of the mechanisms proposed, namely for a simple brain and a social network.Symbolic regression of generative network models • Telmo Menezes & Camille RothScientific Reports 4, Article number: 6284 http://dx.doi.org/10.1038/srep06284See Also: https://github.com/telmomenezes/synthetic

We as Curators Must Now Become the Change We Want to See on The Web

We as Curators Must Now Become the Change We Want to See on The Web | Content in Context | Scoop.it
This post was curated by Robin Good - I changed the title because I think it captures the message for all of us who post or curate anything for our audiences and for ourselves. Robin Good: If you are interested in understanding how "content curation" differentiates itself from simple re-sharing and re-blogging here is a great article by Chris DeLine. Great advice for anyone wanting to become an effective content curator: “Whether in tweets, in blog posts, in podcasts, or in newsletters, be ruthless with your attention. ... Some adopt a strategy of blanket-curation, throwing everything new or fresh or remotely interesting online and letting other consumers make their own value distinctions. Others assume the role of tastemaker, selectively making the decisions themselves. Both have their place, but the former contributes to what Jonathan Haidt calls “the paradox of abundance,” which he says “undermines the quality of our engagement.” How many content-overload websites can you monitor before you become overwhelmed by volume? How many share-explosions does it take before you remove a friend from your Facebook feed? How many Tumblr pages can you pay attention to before the reblogs become a blur? ... Thoughtful, honest, and caring curation isn’t entirely different than creation. After all, the topics you choose to research, to blog about, and to discuss with friends all begin with the process of sifting through the media abyss yourself and singling out worthwhile information." What really counts is to create content that is useful, meaningful and helpful for others, whether from direct hand authorship, or by curating the best existing resources.

... Among his keen insights on the craft, synthesized from the interviews, is a theory of how the creative process works, outlining the four stages of writing: There would seem to be four stages in the composition of a story. First comes the germ of the story, then a period of more or less conscious meditation, then the first draft, and finally the revision, which may be simply ‘pencil work’ as John O’Hara calls it — that is, minor changes in wording — or may lead to writing several drafts and what amounts to a new work. Cowley illustrates each of the four stages with anecdotes from the interviewees....

Why your knowledge-sharing portal will probably not save the world | Kirsty Newman

Thanks Peter for this ... "The Internet is littered with abandoned knowledge-sharing portals, so what questions do you need to ask before jumping in and setting up a new one? Kirsty Newman lists four questions to ask before setting up your knowledge sharing one-stop shop." Comment: this prompted more questions than a simple comment allows me to phrase. In essence, I think what Kirsty says makes a lot of sense, also from the experience we have with setting up and maintaining learning networks.

Of course, don't get discouraged by these notes. It is just that the optimism that people will flock to a portal once it is there, is naive. But if a portal is the best choice, then so be it. My group built a portal for a group of public libraries in the Netherlands (www.biebkracht.nl) and it works, but also takes a lot of work to keep it working. Gilly Salmon's book on e-tivities contains some useful hints, but someone like Jenny Preece long time ago already hinted to this when she discussed lurking.
