  1. Putting organizational complexity in its place, McKinsey Quaterly Next Article Bookmark and Share

    Summary: Not all complexity is bad for business"but executives don’t always know what kind their company has. They should understand what creates complexity for most employees, remove what doesn’t add value, and channel the rest to employees who can handle it effectively.

  2. Metrics: Do metrics matter?, Nature Next Article Bookmark and Share

    Excerpt: No scientist's career can be summarized by a number. He or she spends countless hours troubleshooting experiments, guiding students and postdocs, writing or reviewing grants and papers, teaching, preparing for and organizing meetings, participating in collaborations, advising colleagues, serving on editorial boards and more " none of which is easily quantified. But when that scientist is seeking a job, promotion or even tenure, which of those duties will be rewarded? (...)

  3. Metrics: A profusion of measures, Nature Next Article Bookmark and Share

    Excerpt: That rationale for systematic evaluation hasn't changed much in 100 years, but the evaluation techniques have evolved dramatically. Where Cattell simply asked experts to rank the star performers in a field by merit " "Expert judgment is the best, and in the last resort the only, criterion of performance," he wrote " a host of objective indicators, or metrics, are now used to quantify nebulous notions of scientific quality, impact or prestige. Within the past decade, the development of ever more sophisticated measures has accelerated rapidly (...)

  4. First replicating creature spawned in life simulator, New Scientist Next Article Bookmark and Share

    Excerpts: F YOU found a self-replicating organism living inside your computer, your first instinct might be to reach for the antivirus software. If, however, you are Andrew Wade, an avid player in the two-dimensional, mathematical universe known as the Game of Life, such a discovery is nothing short of an epiphany. (...)
    A first for the game, the replicator demonstrates how astounding complexity can arise from simple beginnings and processes - an echo of life's origins, perhaps. It might help us understand how life on Earth began, or even inspire strategies to build tiny computers.

  5. Predicting human activity, Nature Next Article Bookmark and Share

    Excerpt:
    We usually assume that we do things for a reason, whether we are obeying the dictates of the unconscious, rational self-interest or our genetic predisposition. Yet such determinism cannot predict the diverse range of human behaviour. We are left to suspect that our actions may be no more patterned than coin-tossing.
    In Bursts, physicist Albert-László Barabási explains how this notion of randomness has been undermined by recent research, including his own. We conduct our affairs in bursts, he says: for example, sending out several e-mails in a short space of time and then none for hours, or pottering around our neighbourhood and then travelling 1,000 miles. Barabási explains that we organize tasks in bursts because we prioritize them, attending to each on a timescale that is appropriate to its urgency.

    1. Small But Slow World: How Network Topology and Burstiness Slow Down Spreading, arXiv Next Article Bookmark and Share

      Abstract: Communication networks show the small-world property of short paths, but the spreading dynamics in them turns out slow. We follow the time evolution of information propagation through communication networks by using the SI model with empirical data on contact sequences. We introduce null models where the sequences are randomly shuffled in different ways, enabling us to distinguish between the contributions of different impeding effects. The slowing down of spreading is found to be caused mostly by weight-topology correlations and the bursty activity patterns of individuals.

  6. The Prickly Side of Oxytocin, Science Next Article Bookmark and Share

    Summary: In experiments reported in this week's issue of Science, subjects who received a dose of the social-bonding hormone oxytocin behaved more altruistically toward members of their own group. Yet they also displayed more "defensive aggression" toward outsiders, preemptively punishing members of a competing group when their own group was in danger of suffering a heavy loss.

  7. How to test your decision-making instincts, McKinsey Quaterly Next Article Bookmark and Share

    Excerpt: One of the most important questions facing leaders is when they should trust their gut instincts"an issue explored in a dialogue between Nobel laureate Daniel Kahneman and psychologist Gary Klein titled “Strategic decisions: When can you trust your gut?” published by McKinsey Quarterly in March 2010. Our work on flawed decisions suggests that leaders cannot prevent gut instinct from influencing their judgments. What they can do is identify situations where it is likely to be biased and then strengthen the decision process to reduce the resulting risk.

  8. Darwinian Evolution of Cooperation via Punishment in the "Public Goods" Game, arXiv Next Article Bookmark and Share

    Excerpt: The evolution of cooperation has been a perennial problem for evolutionary biology because cooperation is undermined by selfish cheaters (or "free riders") that profit from cooperators but do not invest any resources themselves. In a purely "selfish" view of evolution, those cheaters should be favored. Evolutionary game theory has been able to show that under certain conditions, cooperation nonetheless evolves stably. One of these scenarios utilizes the power of punishment to suppress free riders, but only if players interact in a structured population where cooperators are likely to be surrounded by other cooperators. Here we show that cooperation via punishment can evolve even in well-mixed populations that play the "public goods" game, if the synergy effect of cooperation is high enough. (...)

    1. Anti-social punishment can prevent the co-evolution of punishment and cooperation, J Theor Biol. Next Article Bookmark and Share

      Excerpt: As there is no reason to assume that cooperators cannot be the target of punishment during evolution, our results demonstrate serious restrictions on the ability of costly punishment to allow the evolution of cooperation in spatially structured populations. Our results also help to make sense of the empirical observation that defectors will sometimes pay to punish cooperators.

  9. Cooperation in Large Networks: An Experimental Approach, SFI Working Papers Next Article Bookmark and Share

    Abstract: We present a new design of a simple public goods experiment with a large number of players, where up to 80 people in a computer lab have the possibility to connect with others in the room to induce more cooperators to contribute to the public good and overcome the social dilemma. This experimental design explores the possibility of social networks to be used and institutional devices to create the same behavioral responses we observe with small groups (e.g. commitments, social norms, reciprocity, trust, shame, guilt) that seem to induce cooperative behavior in the private provision of public goods. The results of our experiment suggest that the structure of the network affects the players’ ability to communicate "and through it, their cooperation levels", and also their willingness to engage in a more costly type of collective action, namely the endogenous creation of new links to individuals previously out of reach. Finally, the information flows in the network seem to reduce uncertainty in the players: players with more links tend to have more stable play strategies.

    1. What's in a crowd? Analysis of face-to-face behavioral networks, arXiv Next Article Bookmark and Share

      Excerpt: The availability of new data sources on human mobility is opening new avenues for investigating the interplay of social networks, human mobility and dynamical processes such as epidemic spreading. Here we analyze data on the time-resolved face-to-face proximity of individuals in large-scale real-world scenarios. We compare two settings with very different properties, a scientific conference and a long-running museum exhibition.

  10. Plasticity, Nature Next Article Bookmark and Share

    Excerpt: Plasticity refers to the capacity of organisms or cells to alter their phenotype in response to changes in their environment. This property can be studied at the level of the genome (by analysing epigenetic modifications), the individual cell, and the organism (during development of the embryo or changes in behaviour in adults, for example).
    In contrast to previously held views, recent studies show that cells are remarkably plastic. Revealing the molecular and cellular mechanisms that underlie this plasticity is a dynamic area of biology and one that holds great promise for developing new therapies.

  11. Title: Evolution of Metabolic Networks: A Computational Framework, SFI Working Papers Next Article Bookmark and Share

    Excerpt: The metabolic architectures of extant organisms share many key pathways such as the citric acid cycle, glycolysis, or the biosynthesis of most amino acids. Several competing hypotheses for the evolutionary mechanisms that shape metabolic networks have been discussed in the literature, each of which finds support from comparative analysis of extant genomes. Alternatively, the principles of metabolic evolution can be studied by direct computer simulation. This requires, however, an explicit implementation of all pertinent components: a universe of chemical reaction upon which the metabolism is built, an explicit representation of the enzymes that implement the metabolism, of a genetic system that encodes these enzymes, and of a fitness function that can be selected for.

  12. What’s driving Africa’s growth, McKinsey Quaterly Next Article Bookmark and Share

    Excerpt: To be sure, many of Africa’s 50-plus individual economies face serious challenges, including poverty, disease, and high infant mortality. Yet Africa’s collective GDP, at $1.6 trillion in 2008, is now roughly equal to Brazil’s or Russia’s, and the continent is among the world’s most rapidly growing economic regions. This acceleration is a sign of hard-earned progress and promise.

  13. A theory of leadership in human cooperative groups, J Theor Biol. Next Article Bookmark and Share

    Excerpt: This paper provides an evolutionary game theoretical model for the acceptance of leadership in cooperative groups. We propose that the effort of a leader can reduce the likelihood that cooperation fails due to free-riding or coordination errors, and that under some circumstances, individuals would prefer to cooperate in a group under the supervision of a leader who receives a share of the group's productivity than to work in an unsupervised group.

  14. Simulated epidemics in an empirical spatiotemporal network of 50,185 sexual contacts, arXiv Next Article Bookmark and Share

    Abstract: We study implications of the dynamical and spatial contact structure between Brazilian escorts and sex-buyers for the spreading of sexually transmitted infections (STI). Despite a highly skewed degree distribution diseases spreading in this contact structure have rather well-defined epidemic thresholds. Temporal effects create a broad distribution of outbreak sizes even if the transmission probability is taken to the hypothetical value of 100%. Temporal correlations speed up outbreaks, especially in the early phase, compared to randomized contact structures. The time-ordering and the network topology, on the other hand, slow down the epidemics. Studying compartmental models we show that the contact structure can probably not support the spread of HIV, not even if individuals were sexually active during the acute infection. We investigate hypothetical means of containing an outbreak and find that travel restrictions are about as efficient as removal of the vertices of highest degree. In general, the type of commercial sex we study seems not like a major factor in STI epidemics.

  15. Integrating fluctuations into distribution of resources in transportation networks, Eur. Phys. J. B Next Article Bookmark and Share

    Abstract: We propose a resource distribution strategy to reduce the average travel time in a transportation network under a given generation rate. Suppose that there are essential resources to avoid congestion in the network as well as some extra resources. The strategy distributes the essential resources by the average loads on the vertices and integrates the fluctuations of the instantaneous loads into the distribution of the extra resources. The fluctuations are calculated with the assumption of unlimited resources, where the calculation is incorporated into the calculation of the average loads without adding to the time complexity. Simulation results show that in scale-free networks, the fluctuation-integrated strategy provides shorter average travel time than a previous distribution strategy while keeping similar robustness; the benefit of our strategy is especially noticeable when the extra resources are scarce.

    1. Steady-state dynamics of the forest fire model on complex networks, Eur. Phys. J. B Next Article Bookmark and Share

      Abstract: Many sociological networks, as well as biological and technological ones, can be represented in terms of complex networks with a heterogeneous connectivity pattern. Dynamical processes taking place on top of them can be very much influenced by this topological fact. In this paper we consider a paradigmatic model of non-equilibrium dynamics, namely the forest fire model, whose relevance lies in its capacity to represent several epidemic processes in a general parametrization. We study the behavior of this model in complex networks by developing the corresponding heterogeneous mean-field theory and solving it in its steady state. We provide exact and approximate expressions for homogeneous networks and several instances of heterogeneous networks. A comparison of our analytical results with extensive numerical simulations allows to draw the region of the parameter space in which heterogeneous mean-field theory provides an accurate description of the dynamics, and enlights the limits of validity of the mean-field theory in situations where dynamical correlations become important.

  16. Regulatory networks and connected components of the neutral space: A look at functional islands, Eur. Phys. J. B Next Article Bookmark and Share

    Abstract: The functioning of a living cell is largely determined by the structure of its regulatory network, comprising non-linear interactions between regulatory genes. An important factor for the stability and evolvability of such regulatory systems is neutrality " typically a large number of alternative network structures give rise to the necessary dynamics. Here we study the discretized regulatory dynamics of the yeast cell cycle [Li et al., PNAS, 2004] and the set of networks capable of reproducing it, which we call functional. Among these, the empirical yeast wildtype network is close to optimal with respect to sparse wiring. Under point mutations, which establish or delete single interactions, the neutral space of functional networks is fragmented into ≈ 4.7 - 108 components. One of the smaller ones contains the wildtype network. On average, functional networks reachable from the wildtype by mutations are sparser, have higher noise resilience and fewer fixed point attractors as compared with networks outside of this wildtype component.

  17. Structural Drift: The Population Dynamics of Sequential Learning, SFI Working Papers Next Article Bookmark and Share

    Abstract: We introduce a theory of sequential causal inference in which learners in a chain estimate a structural model from their upstream "teacher" and then pass samples from the model to their downstream "student". It extends the population dynamics of genetic drift, recasting Kimura's selectively neutral theory as a special case of a generalized drift process using structured populations with memory. We examine the diffusion and fixation properties of several drift processes and propose applications to learning, inference, and evolution. We also demonstrate how the organization of drift process space controls fidelity, facilitates innovations, and leads to information loss in sequential learning with and without memory.

  18. Obituary: Martin Gardner (1914"2010), Nature Next Article Bookmark and Share

    Excerpt: From the mid-1950s to the early 1980s, perhaps the most well-known section of Scientific American was the 'Mathematical games' column of Martin Gardner. In recognition of its success, three eminent mathematicians dedicated their 1982 book Winning Ways for Your Mathematical Plays to Gardner, who, they wrote, “brought more mathematics to more millions than anyone else”. Yet Gardner was not a mathematician. His only degree was in philosophy.

    1. Biology's First Law: The Tendency for Diversity and Complexity to Increase in Evolutionary Systems, Chicago University Press Next Article Bookmark and Share

      Summary:
      Life on earth is characterized by three striking phenomena that demand explanation: adaptation"the fit between organism and environment; diversity"the great variety of organisms; and complexity"the enormous intricacy of their internal structure. Natural selection explains adaptation. But what explains diversity and complexity? This book argues that there exists in evolution a spontaneous tendency toward increased diversity and complexity, one that acts whether natural selection is present or not. They call this tendency a biological law"the Zero-Force Evolutionary Law. This law invites a reconceptualization of the field of the same sort that Newton’s First Law brought to physics.

    3. The Rational Optimist: How Prosperity Evolves, Harper Next Article Bookmark and Share

      Summary:
      Ideas have sex, in Ridley's schema; they follow a process of natural selection of their own, and as long as they continue to do so, there is reason to retire apocalyptic pessimism about the future of our species. Ridley (The Red Queen) posits that as long as civilization engages in exchange and specialization, we will be able to reinvent ourselves and responsibly use earthly resources ad infinitum. Ridley puts current perceptions about violence, wealth, and the environment into historical perspective, reaching back thousands of years to advocate global free trade, smaller government, and the use of fossil fuels.

    4. The Cybernetic Brain: Sketches of Another Future, University Of Chicago Press Next Article Bookmark and Share

      Summary:
      The Cybernetic Brain explores a largely forgotten group of British thinkers, including Grey Walter, Ross Ashby, Gregory Bateson, R. D. Laing, Stafford Beer, and Gordon Pask, and their singular work in a dazzling array of fields. Psychiatry, engineering, management, politics, music and architecture all come into play as Pickering follows the history of cybernetics’ impact on the world, from contemporary robotics and complexity theory to the Chilean economy under Salvador Allende. What underpins this fascinating history, Pickering contends, is a shared but unconventional vision of the world as ultimately unknowable, a place where genuine novelty is always emerging.
