  1. Foundations of Societal Inequality, Science Next Article Bookmark and Share

    Excerpts: Economic and social outcomes, including incomes, poverty, life expectancy, and infant mortality, differ widely between societies. Such inequalities within countries also vary to a great degree. Despite the importance and ubiquity of these differences, their sources are poorly understood and hotly debated. (...) On page 682 in this issue, Borgerhoff Mulder et al. (3) show that wealth inequality in 21 historical and contemporary "small-scale societies" is determined by the intergenerational transmission of different types of assets. What makes the findings important for social science is the link between inequality and institutions that regulate the inheritability of assets.

  2. Can an Infectious Disease Genomics Project Predict and Prevent the Next Pandemic?, PLoS Biol Next Article Bookmark and Share

    Excerpt: (...) we believe that it is possible to expand genomics into a more global technology that can also focus on diseases of resource-limited settings. This goal can be achieved if genomics is made a global priority. We feel one way to move in this direction is through a comprehensive approach to infectious diseasesâ€"i.e., an Infectious Disease Genomics Projectâ€"that would mirror the Human Genome Project. Without an active, unified effort specifically focused on allowing actors at any level to participate in the genomics revolution, infectious diseases that primarily affect the poor will likely not achieve the same level of scientifici advancement as diseases affecting the wealthy.

    1. The Transmissibility and Control of Pandemic Influenza A (H1N1) Virus, Science Next Article Bookmark and Share

      Excerpt: Pandemic influenza A (H1N1) 2009 (pandemic H1N1) is spreading throughout the planet. It has become the dominant strain in the Southern Hemisphere, where the influenza season has now ended. Here, on the basis of reported case clusters in the United States, we estimated the household secondary attack rate for pandemic H1N1 to be 27.3% (...) We used a simulation model to evaluate the effectiveness of vaccination strategies in the United States for fall 2009. If a vaccine were available soon enough, vaccination of children, followed by adults, reaching 70% overall coverage, in addition to high-risk and essential workforce groups, could mitigate a severe epidemic.

  3. Development and Climate Change, Science Next Article Bookmark and Share

    Excerpt: No country is immune to climate change, but the developing world will bear the brunt of the effects, including some 75 to 80% of the costs of anticipated damages.* Millions in densely populated coastal areas and in island nations will lose their homes as the sea level rises, while poor people will face crop failures, reduced agricultural productivity, and increased hunger, malnutrition, and disease. Extreme events such as droughts, floods, and forest fires will become more frequent, making it even harder for developing countries to attain the United Nations' Millennium Development Goals of 2015. A "climate-smart" world is possible in our time. But to ensure a safe and sustainable future, all nations must act now, act together, and act differently.

    1. Biodiversity and Climate Change, Science Next Article Bookmark and Share

      Excerpt: Over the past decade, several models have been developed to predict the impact of climate change on biodiversity. Results from these models have suggested some alarming consequences of climate change for biodiversity, predicting, for example, that in the next century many plants and animals will go extinct (1) and there could be a large-scale dieback of tropical rainforests (2). However, caution may be required in interpreting results from these models (...)

  4. Structure of Protein Interaction Networks and Their Implications on Drug Design, PLoS Comput Biol Next Article Bookmark and Share

    Summary: Genome-wide data on interactions between proteins are now available, and networks of protein interactions are the keys to understanding diseases and finding accurate drug targets. This study revealed that the architectural properties of the backbones of protein interaction networks (PINs) were similar to those of the Internet router-level topology by using statistical analyses of genome-wide budding yeast and human PINs. This type of network is known as a highly optimized tolerance (HOT) network that is robust against failures in its components and that ensures high levels of communication. Moreover, we also found that a large number of the most successful drug-target proteins are on the backbone of the human PIN. We made a list of proteins on the backbone of the human PIN, which may help drug companies to search more efficiently for new drug targets.

  5. Why three buses come at once, and how to avoid it, New Scientist Next Article Bookmark and Share

    Excerpt:
    Bused up. Commuters can help keep transport moving (Image: Tony Kyriacou/Rex Features)
    Anyone who has waited for a bus knows the routine: you wait far longer than you should, then three come along at once. The problem, called "platooning", plagues buses, trains and even elevators. Now systems complexity researchers Carlos Gershenson and Luis Pineda of the National Autonomous University of Mexico have devised a mathematical model that shows how the problem might be prevented (...)

    1. Transforming Transportation, Frontier Economy Next Article Bookmark and Share

      Excerpt: Why do we have to wait forever for a bus, and then three come together? In this interview Carlos Gershenson talks about understanding public transportation using computer simulations.

    2. Why Does Public Transport Not Arrive on Time? The Pervasiveness of Equal Headway Instability, PLoS ONE Next Article Bookmark and Share

      Excerpt: The equal headway instability phenomenon is pervasive in public transport systems. This instability is characterized by an aggregation of vehicles that causes inefficient service. [...] Finally, we provide technological and social suggestions for engineers and passengers to help achieve equal headways and thus reduce delays.

  6. Rachel Armstrong: Architecture that repairs itself?, TED.com Next Article Bookmark and Share

    About this talk: Venice, Italy is sinking. To save it, Rachel Armstrong says we need to outgrow architecture made of inert materials and, well, make architecture that grows itself. She proposes a not-quite-alive material that does its own repairs and sequesters carbon, too.

  7. Accelerating the pace of discovery by changing the peer review algorithm, arXiv Next Article Bookmark and Share

    Excerpt: The number of scientific publications is constantly rising, increasing the strain on the review process. The number of submissions is actually higher, as each manuscript is often reviewed several times before publication. To face the deluge of submissions, top journals reject a considerable fraction of manuscripts without review, potentially declining manuscripts with merit. The situation is frustrating for authors, reviewers and editors alike. Recently, several editors wrote about the ``tragedy of the reviewer commons', advocating for urgent corrections to the system. Almost every scientist has ideas on how to improve the system, but it is very difficult, if not impossible, to perform experiments to test which measures would be most effective. Surprisingly, relatively few attempts have been made to model peer review. Here I implement a simulation framework in which ideas on peer review can be quantitatively tested. (...)

  8. ‘Glocal’ Robustness Analysis and Model Discrimination for Circadian Oscillators, PLoS Comput Biol Next Article Bookmark and Share

    Summary: Robustness is an intrinsic property of many biological systems. To quantify the robustness of a model that represents such a system, two approaches exist: global methods assess the volume in parameter space that is compliant with the proper functioning of the system; and local methods, in contrast, study the model for a given parameter set and determine its robustness. Local methods are fundamentally biased due to the a priori choice of a particular parameter set. Our ‘glocal’ analysis combines the two complementary approaches and provides an objective measure of robustness. We apply this method to two prominent, recent models of the cyanobacterial circadian oscillator. Our results allow discriminating the two models based on this analysis: both global and local measures of robustness favor one of the two models. The ‘glocal’ method also identifies key factors that influence robustness. For instance, we find that in both models the most fragile reactions are the ones that affect the concentration of the feedback component.

    1. Extreme Degeneracies Characterize the Module Identification Problem for Complex Networks, SFI Working Papers Next Article Bookmark and Share

      Excerpt: Identifying modular structure in complex networks is a fundamental task for understanding the function, dynamics, robustness and evolution of complex biological, technological and social systems. Although widely used in practice, the accuracy of popular identification techniques, such as the one based on optimizing the quantity called modularity, remains poorly characterized. Here, we present a systemic and critical analysis of this method.

  9. Quantum speed limit, Nature Next Article Bookmark and Share

    Excerpts: The processing speed of computer chips has doubled almost every two years for the past 40, as engineers have crammed ever more transistors into smaller circuits. But according to Lev Levitin and Tommaso Toffoli of Boston University in Massachusetts, chips will ultimately hit a roadblock, limited by the minimum time it takes for a particle to flip from one quantum state to another â€" a fundamental step in any information system. (...) Levitin says that, at the current doubling pace, computing speed will reach this limit in about 80 years.

  10. The complexity of advice-giving, Complexity Next Article Bookmark and Share

    Abstract: Advice-giving about personal problems is a common form of human interaction. However, an open question is whether there is an abstract and general logic that explains how advice-giving works. In this study, we addressed this question from the perspective of dynamical systems. We measured the nonlinear dynamics of advice-giving by using recurrence quantification analysis. Analyzing 600 texts of request for advice and the advice given, our results uncover a typical logic of advice-giving, and suggest that advice-giving may be understood as a dynamic manipulation of perspective-taking.

  11. Cooperation between non-kin in animal societies, Nature Next Article Bookmark and Share

    Abstract: Explanations of cooperation between non-kin in animal societies often suggest that individuals exchange resources or services and that cooperation is maintained by reciprocity. But do cooperative interactions between unrelated individuals in non-human animals really resemble exchanges or are they a consequence of simpler mechanisms? Firm evidence of reciprocity in animal societies is rare and many examples of cooperation between non-kin probably represent cases of intra-specific mutualism or manipulation.

    1. Cooperation, Norms, and Conflict: A Unified Approach, SFI Working Papers Next Article Bookmark and Share

      Abstract: Cooperation is of utmost importance to society, but is often challenged by individual self-interests. While game theory has studied this problem extensively, there is little work on interactions within and across groups with heterogeneous preferences. Yet, interactions between people with incompatible interests often yield conflict, since behavior that is considered cooperative by one population might be perceived as non-cooperative by another. To understand the outcome of such competitive interactions, we study game-dynamical replicator equations for multiple populations with incompatible preferences and different power to reveal, for example, what mechanisms can foster the evolution of behavioral norms? When does cooperation fail, leading to conflict or even to revolutions? What incentives are needed to reach peaceful agreements? Our quantitative analysis reveals some striking results, significant for society, law, and economics.

    2. Evolutionary Dynamics of Populations with Conflicting Interactions: Classification and Analytical Treatment Considering Asymmetry and Power, arXiv Next Article Bookmark and Share

      Excerpts: Evolutionary game theory has been successfully used to investigate the dynamics of systems, in which many entities have competitive interactions. From a physics point of view, it is interesting to study conditions under which a coordination or cooperation of interacting entities will occur, be it spins, particles, bacteria, animals, or humans. (...) While these results are interesting from a physics point of view, they are also relevant for social, economic, and biological systems, as they allow one to understand conditions for (1) the breakdown of cooperation, (2) the coexistence of different behaviors ("subcultures"), (2) the evolution of commonly shared behaviors ("norms"), and (4) the occurence of polarization or conflict. We point out that norms have a similar function in social systems that forces have in physics.

  12. Unobserved punishment supports cooperation, Journal of Public Economics Next Article Bookmark and Share

    Excerpt: Our experiment shows that subjects will engage in costly punishment even when it will not be observed until the end of the session, which supports the view that agents enjoy punishment. Moreover, players continue to cooperate when punishment is unobserved, perhaps because they (correctly) anticipate that shirkers will be punished: Fear of punishment can be as effective at promoting contributions as punishment itself.

    1. Influence of the variance of degree distributions on the evolution of cooperation in complex networks, Physica A Next Article Bookmark and Share

      Excerpt: We study how initial network structure affects the evolution of cooperation in a spatial prisoner’s dilemma game. The network structure is characterized by various statistical properties. Among those properties, we focus on the variance of the degree distribution, and inquire how it affects the evolution of cooperation by three methods of imitation. For every method, it was found that a scale-free network does not always promote the evolution of cooperation, and that there exists an appropriate value of the variance, at which cooperation is optimal.

  13. Multilevel Selection in Models of Prebiotic Evolution II: A Direct Comparison of Compartmentalization and Spatial Self-Organization, PLoS Comput Biol Next Article Bookmark and Share

    Summary: The origin of life has ever been attracting scientific inquiries. The RNA world hypothesis suggests that, before the evolution of DNA and protein, primordial life was based on RNA-like molecules both for information storage and chemical catalysis. In the simplest form, an RNA world consists of RNA molecules that can catalyze the replication of their own copies. Thus, an interesting question is whether a system of RNA-like replicators can increase its complexity through Darwinian evolution and approach the modern form of life. It is, however, known that simple natural selection acting on individual replicators is insufficient to account for the evolution of complexity due to the evolution of parasite-like templates. Two solutions have been suggested: compartmentalization of replicators by membranes (i.e., protocells) and spatial self-organization of a replicator population. Here, we make a direct comparison of the two suggestions by computer simulations. Our results show that the two suggestions can lead to unanticipated and contrasting consequences in the long-term evolution of replicating molecules. The results also imply a novel advantage in the spatial self-organization for the evolution of complexity in RNA-like replicator systems.

  14. Compression-based investigation of the dynamical properties of cellular automata and other systems, arXiv Next Article Bookmark and Share

    Abstract: A method for studying the qualitative dynamical properties of abstract computing machines based on the approximation of their program-size complexity using a general lossless compression algorithm is presented. It is shown that the compression-based approach classifies cellular automata (CA) into clusters according to their heuristic behavior, with these clusters showing a correspondence with Wolfram's main classes of CA behavior. A compression based method to estimate a characteristic exponent to detect phase transitions and measure the resiliency or sensitivity of a system to its initial conditions is also proposed, constituting a compression-based framework for investigating the dynamical properties of cellular automata and other systems.

  15. Benefits of diversity, communication costs, and public opinion dynamics, Complexity Next Article Bookmark and Share

    Abstract: We study the dynamics of public opinion in a model where agents change their opinions as a result of random binary encounters if the opinion difference is below their individual thresholds that evolve over time. We ground these thresholds in a simple individual cost-benefit analysis with linear benefits of diversity and quadratic communication costs. We clarify and deepen the results of earlier continuous-opinion dynamics models (Deffuant et al., Adv Complex Systems 2000, 3, 87-98; Weisbuch et al., Complexity 2002, 7, 55-63) and establish several new results regarding the patterns of opinions in the asymptotic state and the cluster formation time.

    1. The Non-linear Dynamics of Meaning-Processing in Social Systems, arXiv Next Article Bookmark and Share

      Excerpt: Social order cannot be considered as a stable phenomenon because it contains an order of reproduced expectations. When the expectations operate upon one another, they generate a non-linear dynamics that processes meaning. Specific meaning can be stabilized, for example, in social institutions, but all meaning arises from a horizon of possible meanings. Using Luhmann's (1984) social systems theory and Rosen's (1985) theory of anticipatory systems, I submit equations for modeling the processing of meaning in inter-human communication.

  16. Solvable Model of Spiral Wave Chimeras, arXiv Next Article Bookmark and Share

    Abstract: Spiral waves are ubiquitous in two-dimensional systems of chemical or biological oscillators coupled locally by diffusion. At the center of such spirals is a phase singularity, a topological defect where the oscillator amplitude drops to zero. But if the coupling is nonlocal, a new kind of spiral can occur, with a circular core consisting of desynchronized oscillators running at full amplitude. Here we provide the first analytical description of such a spiral wave chimera, and use perturbation theory to calculate its rotation speed and the size of its incoherent core.

  17. Male or Female? For Honeybees, a Single Gene Makes All the Difference, PLoS Biol Next Article Bookmark and Share

    Excerpt: Male or female? How genes send a developing embryo down one path or the other varies substantially among species. In honeybees, it boils down to whether a particular chromosomal location has the same version of a gene (called homozygous) or two different versions (heterozygous).

  18. The Development of Social Simulation as Reflected in the First Ten Years of JASSS: a Citation and Co-Citation Analysis, JASSS Next Article Bookmark and Share

    Excerpt: [...] First, we use citation analysis to identify the most influential publications and to verify characteristics of social simulation such as its multidisciplinary nature. Then, we perform a co-citation analysis to visualize the intellectual structure of social simulation and its development. Overall, the analysis shows social simulation both in its early stage and during its first steps towards becoming a more differentiated discipline.

      Excerpt: A replication and analysis of the Artificial Anasazi model is presented. It is shown that the success of replicating historical data is based on two parameters that adjust the carrying capacity of the Long House Valley. Compared to population estimates equal to the carrying capacity the specific agent behavior contributes only a modest improvement of the model to fit the archaeological records.

      Summary:
      This treasure of popular science by the Russian biophysicist Mikhail V. Volkenstein is at last, more than twenty years after its appearance in Russian, available in English translation. As its title Entropy and Information suggests, the book deals with the thermodynamical concept of entropy and its interpretation in terms of information theory. The author shows how entropy is not to be considered a mere shadow of the central physical concept of energy, but more appropriately as a leading player in all of the major natural processes: physical, chemical, biological, evolutionary, and even cultural.

      Summary:
      This volume represents a radical departure from the current philosophical duopoly in the area of foundations of probability, that is, the frequency and subjective theories. One of the main new ideas is a set of scientific laws of probability. The new laws are simple, intuitive and, last but not least, they agree well with the contents of current textbooks on probability. Another major new claim is that the "frequency statistics" has nothing in common with the "frequency philosophy of probability," contrary to popular belief.
