Using sociometers to quantify social interaction patterns

Using sociometers to quantify social interaction patterns | networks and network weaving | Scoop.it
Research on human social interactions has traditionally relied on self-reports. Despite their widespread use, self-reported accounts of behaviour are prone to biases and necessarily reduce the range of behaviours, and the number of subjects, that may be studied simultaneously. The development of ever smaller sensors makes it possible to study group-level human behaviour in naturalistic settings outside research laboratories. We used such sensors, sociometers, to examine gender, talkativeness and interaction style in two different contexts. Here, we find that in the collaborative context, women were much more likely to be physically proximate to other women and were also significantly more talkative than men, especially in small groups. In contrast, there were no gender-based differences in the non-collaborative setting. Our results highlight the importance of objective measurement in the study of human behaviour, here enabling us to discern context specific, gender-based differences in interaction style.

Complexity: A Very Short Introduction (by John H. Holland)

The importance of complexity is well-captured by Hawking's comment: "Complexity is the science of the 21st century". From the movement of flocks of birds to the Internet, environmental sustainability, and market regulation, the study and understanding of complex non-linear systems has become highly influential over the last 30 years.

In this Very Short Introduction, one of the leading figures in the field, John Holland, introduces the key elements and conceptual framework of complexity. From complex physical systems such as fluid flow and the difficulties of predicting weather, to complex adaptive systems such as the highly diverse and interdependent ecosystems of rainforests, he combines simple, well-known examples -- Adam Smith's pin factory, Darwin's comet orchid, and Simon's 'watchmaker' -- with an account of
the approaches, involving agents and urn models, taken by complexity theory.

Crowdsourcing for Participatory Democracies: Efficient Elicitation of Social Choice Functions

We present theoretical and empirical results demonstrating the usefulness of voting rules for participatory democracies. We first give algorithms which efficiently elicit \epsilon-approximations to two prominent voting rules: the Borda rule and the Condorcet winner. This result circumvents previous prohibitive lower bounds and is surprisingly strong: even if the number of ideas is as large as the number of participants, each participant will only have to make a logarithmic number of comparisons, an exponential improvement over the linear number of comparisons previously needed. We demonstrate the approach in an experiment in Finland's recent off-road traffic law reform, observing that the total number of comparisons needed to achieve a fixed \epsilon approximation is linear in the number of ideas and that the constant is not large.
Finally, we note a few other experimental observations which support the use of voting rules for aggregation. First, we observe that rating, one of the common alternatives to ranking, manifested effects of bias in our data. Second, we show that very few of the topics lacked a Condorcet winner, one of the prominent negative results in voting. Finally, we show data hinting at a potential future direction: the use of partial rankings as opposed to pairwise comparisons to further decrease the elicitation time.

Coaction versus reciprocity in continuous-time models of cooperation

Cooperating animals frequently show closely coordinated behaviours organized by a continuous flow of information between interacting partners. Such real-time coaction is not captured by the iterated prisoner׳s dilemma and other discrete-time reciprocal cooperation games, which inherently feature a delay in information exchange. Here, we study the evolution of cooperation when individuals can dynamically respond to each other׳s actions.

Thanks for this great scoop June! Would not expect les form SantaFe Institute and MIT - here is my favourite quote:


“People tend to think of cities as people, buildings, roads, pipes, and so on,” he says. “But at a more fundamental level, cities are really about connections. These connections form networks of people and organizations that enable the production of all products of civilization, from modern economies and fast innovation to complex bureaucracies and political institutions.”


“That social interactions per person increase with city size begins to explain how so many socioeconomic quantities, from GDP to violent crime, scale superlinearly,” he adds. “We had developed theory that predict the superlinear growth of social connections in the way we observe here, but this is the first time that we can observe this phenomenon directly and explore it in detail! It is tremendously exciting.”

Multiple percolation transitions in a configuration model of a network of networks

Multiple percolation transitions in a configuration model of a network of networks | networks and network weaving | Scoop.it

Recently much attention has been paid to the study of the robustness of interdependent and multiplex networks and, in particular, the networks of networks. The robustness of interdependent networks can be evaluated by the size of a mutually connected component when a fraction of nodes have been removed from these networks. Here we characterize the emergence of the mutually connected component in a network of networks in which every node of a network (layer) alpha is connected with q_alpha its randomly chosen replicas in some other networks and is interdependent of these nodes with probability r. We find that when the superdegrees q_alpha of different layers in a network of networks are distributed heterogeneously, multiple percolation phase transition can occur. We show that, depending on the value of r, these transition are continuous or discontinuous.

Detecting Communities Based on Network Topology

Detecting Communities Based on Network Topology | networks and network weaving | Scoop.it

Network methods have had profound influence in many domains and disciplines in the past decade. Community structure is a very important property of complex networks, but the accurate definition of a community remains an open problem. Here we defined community based on three properties, and then propose a simple and novel framework to detect communities based on network topology. We analyzed 16 different types of networks, and compared our partitions with Infomap, LPA, Fastgreedy and Walktrap, which are popular algorithms for community detection. Most of the partitions generated using our approach compare favorably to those generated by these other algorithms. Furthermore, we define overlapping nodes that combine community structure with shortest paths. We also analyzed the E. Coli. transcriptional regulatory network in detail, and identified modules with strong functional coherence.

Community is a more complex and organic organizing than teams. Teams are inherently hierarchical with predetermined goals. Communities are fluid and the goals are continuously being negotiated. Schools and classrooms are better served to be thought of as communities with overlapping qualities and permeable boundaries with other communities.

Early Warning Signs in Social-Ecological Networks

Early Warning Signs in Social-Ecological Networks | networks and network weaving | Scoop.it

A number of social-ecological systems exhibit complex behavior associated with nonlinearities, bifurcations, and interaction with stochastic drivers. These systems are often prone to abrupt and unexpected instabilities and state shifts that emerge as a discontinuous response to gradual changes in environmental drivers. Predicting such behaviors is crucial to the prevention of or preparation for unwanted regime shifts. Recent research in ecology has investigated early warning signs that anticipate the divergence of univariate ecosystem dynamics from a stable attractor. To date, leading indicators of instability in systems with multiple interacting components have remained poorly investigated. This is a major limitation in the understanding of the dynamics of complex social-ecological networks. Here, we develop a theoretical framework to demonstrate that rising variance—measured, for example, by the maximum element of the covariance matrix of the network—is an effective leading indicator of network instability. We show that its reliability and robustness depend more on the sign of the interactions within the network than the network structure or noise intensity. Mutualistic, scale free and small world networks are less stable than their antagonistic or random counterparts but their instability is more reliably predicted by this leading indicator. These results provide new advances in multidimensional early warning analysis and offer a framework to evaluate the resilience of social-ecological networks.

How collective comparisons emerge without individual comparisons of the options

Collective decisions in animal groups emerge from the actions of individuals who are unlikely to have global information. Comparative assessment of options can be valuable in decision-making. Ant colonies are excellent collective decision-makers, for example when selecting a new nest-site.

Social Technology and the Changing Context of Leadership

Social Technology and the Changing Context of Leadership | networks and network weaving | Scoop.it

Social technologies with their inherent democratic, anti-hierarchical quality easily transcend internal and external boundaries, suddenly creating a powerful thrust for horizontal collaboration and participation. They give each and every member of an organization a creative voice and enable real-time virtual connectivity in a way we have never seen before. This makes them a great catalyst for the organizational principles that are required by the new leadership context of the 21st century.

The Cold Dark Path

The Cold Dark Path | networks and network weaving | Scoop.it
Two Competing Loops


This week at the first meeting of the League of Social Intrapreneurs in Melbourne I was introduced to the Berkana Institute two loops theory of change. The model of change in complex systems resonated immediately.


When a system nears its peak, change agents identify the need for alternatives and drop out.  They connect and begin to explore alternatives nourishing a new system through experimentation. Eventually the stories of their success illuminates the change to those who remain in the old declining system.


A four step model with four simple verbs seems clear and straightforward. Why is it that the path of change is such a cold dark path?


Nobody Warns You about the Dip


Stepping out of a warm and comfortable ongoing system with its present day rewards is a daunting uncertain choice however bleak the future of that system may look. Those with most to gain will oppose the agents of change who name the issues and start to work on alternatives. Opposition will not always be fair or balanced.




Sign you made it as a change agent: someone misapplies a political label, impugns your integrity or questions your sanity. #caww


— Simon Terry (@simongterry)

July 3, 2014






Most difficult of all is that dip in the diagram above. The uncertainty and the need to build a new complex future means the alternative system starts along way back and with a great deal more risk. Selling another path even to yourself can be a challenge in this scenario.


All the discussions about collaboration, requests for advice and stories shared among change agents at the League of Social Entrepreneurs, in Responsive Organisation, in Change Agents Worldwide or in other conversations that I have with unreasonable people belong at the bottom of the loop where people struggle nourishing new alternatives.


We must embrace the fact that the road to change is a road with dips and uncertainties. Proceeding any other way does not prepare people for the work ahead.


Nourishing Change Takes Hard Work


Most change fails after the connect stage.  Declaring a need for change is initially easy and exhilarating. Manifestos are thrilling. Connecting with other like minded people has a wonderful effect for the spirits and is a great way to reinforce the need for change.


Then nothing happens for a really long time. It grows cold and dark on the path of change.


Lots of drudgery dogs those walking the cold dark path of change. Meetings need to be organised and venues found. Compromises need to be negotiated between people who are 99% aligned. Factions and fragmentation occurs and saps the energy of everyone. More change agents need to be recruited, especially for the work. Experiments need to be agreed, funded and run. Failed experiments need to be cleaned up. New experiments agreed, funded and implemented. Success needs to be found. Someone needs to find money or work out the details of the new model. Communication materials don’t write themselves. Just when success seems inevitable the dying system finds a way to set you back.


Change falls apart when the connected agents of change won’t work the experiments long or hard enough to nourish the success of the new system. If they won’t invest the time to build new connections, share successes, to solve the daily issues and to innovate a path forward then the nourish stage will never offer an opportunity to others to join in the change.


If the organisers of the first meet up about a change end up with all the actions, then a change initiative has work to do to find others to nourish the change. Engaging others in the work matters more than engaging them in the idea of the change.


Join in the Work


Lots of people want to join change at the exhilarating beginning and again at the celebratory end. Traditional management focus only on the beginnings and the endings but leadership is found in realising the collective potential of the journey.


The question is who is willing to walk the cold dark road. Those change agents who do the leadership work of nourishing new experiments shape the future. That path is hard but the work is the most purposeful and rewarding.

Et que l'effet boule de neige, engagement d'un nombre toujours croissant de participants actifs dans le projet de changement est recherché et facilité sans relâche.

Frontiers in Ecology Evolution and Complexity

Frontiers in Ecology Evolution and Complexity | networks and network weaving | Scoop.it

Advances in molecular biology, remote sensing, systems biology, bioinformatics, non-linear science, the physics of complex systems and other fields have rendered a great amount of data that remain to be integrated into models and theories that are capable of accounting for the complexity of ecological systems and the evolutionary dynamics of life. It is thus necessary to provide a solid basis to discuss and reflect on these and other challenges both at the local and global scales. This volume aims to delineate an integrative and interdisciplinary view that suggests new avenues in research and teaching, critically discusses the scope of the diverse methods in the study of complex systems, and points at key open questions. Finally, this book will provide students and specialists with a collection of high quality open access essays that will contribute to integrate Ecology, Evolution and Complexity in the context of basic research and in the field of Sustainability Sciences

The Strength of the Strongest Ties in Collaborative Problem Solving

The Strength of the Strongest Ties in Collaborative Problem Solving | networks and network weaving | Scoop.it
Complex problem solving in science, engineering, and business has become a highly collaborative endeavor. Teams of scientists or engineers collaborate on projects using their social networks to gather new ideas and feedback. Here we bridge the literature on team performance and information networks by studying teams' problem solving abilities as a function of both their within-team networks and their members' extended networks. We show that, while an assigned team's performance is strongly correlated with its networks of expressive and instrumental ties, only the strongest ties in both networks have an effect on performance. Both networks of strong ties explain more of the variance than other factors, such as measured or self-evaluated technical competencies, or the personalities of the team members. In fact, the inclusion of the network of strong ties renders these factors non-significant in the statistical analysis. Our results have consequences for the organization of teams of scientists, engineers, and other knowledge workers tackling today's most complex problems.
