  1. The second economy, McKinsey Quaterly Next Article Bookmark and Share

    Excerpt: I want to argue that something deep is going on with information technology, something that goes well beyond the use of computers, social media, and commerce on the Internet. Business processes that once took place among human beings are now being executed electronically. They are taking place in an unseen domain that is strictly digital. On the surface, this shift doesn’t seem particularly consequentialâ€"it’s almost something we take for granted. But I believe it is causing a revolution no less important and dramatic than that of the railroads. It is quietly creating a second economy, a digital one.

  4. Swayed by Friends or by the Crowd?, HP Labs Next Article Bookmark and Share

    Abstract: We have conducted three empirical studies of the effects of friend recommendations and general ratings on how online users make choices. These two components of social influence were investigated through user studies on Mechanical Turk. We find that for a user deciding between two choices an additional rating star has a much larger effect than an additional friend’s recommendation on the probability of selecting an item. Equally important, negative opinions from friends are more influential than positive opinions, and people exhibit more random behavior in their choices when the decision involves less cost and risk. Our results can be generalized across different demographics, implying that individuals trade off recommendations from friends and ratings in a similar fashion.

  5. Christoph Adami: Finding life we can't imagine, TED.com Next Article Bookmark and Share

    About this talk: How do we search for alien life if it's nothing like the life that we know? At TEDxUIUC Christoph Adami shows how he uses his research into artificial life -- self-replicating computer programs -- to find a signature, a 'biomarker,' that is free of our preconceptions of what life is.

    1. Ian Ritchie: The day I turned down Tim Berners-Lee, TED.com Next Article Bookmark and Share

      About this talk: Imagine it's late 1990, and you've just met a nice young man named Tim Berners-Lee, who starts telling you about his proposed system called the World Wide Web. Ian Ritchie was there. And ... he didn't buy it. A short story about information, connectivity and learning from mistakes.

  6. Good Fences: The Importance of Setting Boundaries for Peaceful Coexistence, arXiv Next Article Bookmark and Share

    Excerpt: We consider the conditions of peace and violence among ethnic groups, testing a theory designed to predict the locations of violence and interventions that can promote peace. Characterizing the model's success in predicting peace requires examples where peace prevails despite diversity. Switzerland is recognized as a country of peace, stability and prosperity. This is surprising because of its linguistic and religious diversity that in other parts of the world lead to conflict and violence. Here we analyze how peaceful stability is maintained. Our analysis shows that peace does not depend on integrated coexistence, but rather on well defined topographical and political boundaries separating groups.

  7. Common Organizing Mechanisms in Ecological and Socio-economic Networks, arXiv Next Article Bookmark and Share

    Excerpt: Previous work has shown that species interacting in an ecosystem and actors transacting in an economic context may have notable similarities in behavior. However, the specific mechanism that may underlie similarities in nature and human systems has not been analyzed. Building on stochastic food-web models, we propose a parsimonious bipartite-cooperation model that reproduces the key features of mutualistic networks - degree distribution, nestedness and modularity -- for both ecological networks and socio-economic networks.

    1. Signalling and the Evolution of Cooperative Foraging in Dynamic Environments, PLoS Comput Biol Next Article Bookmark and Share

      Excerpt: (…) we examine a social foraging system where individuals evolve to signal to conspecifics when they locate a resource. We show that in some environments, cooperative signalling is sustained through a form of indirect reciprocation, as a signalling phenotype is more likely to be the beneficiary of a signal from a conspecific in the future. This effect naturally occurs as a result of the foraging dynamic and, depending on the environment, such as how resources are distributed and how difficult they are to track, will compensate for relatively large costs of signalling.

  9. Distinguishing Anticipation from Causality: Anticipatory Bias in the Estimation of Information Flow, Phys. Rev. Lett. Next Article Bookmark and Share

    Abstract: We report that transfer entropy estimates obtained from low-resolution and/or small data sets show net information flow away from a purely anticipatory element whereas transfer entropy calculated using exact distributions show the flow towards it. This means that for real-world data sets anticipatory elements can appear to be strongly driving the network dynamics even when there is no possibility of such an influence. Furthermore, we show that in the low-resolution limit there is no statistic that can distinguish anticipatory elements from causal ones.

    1. Relating Fisher information to order parameters, Phys. Rev. E Next Article Bookmark and Share

      Excerpt: The study highlights the generality of Fisher information as a measure that can be applied to a broad range of systems, particularly those where the determination of order parameters is cumbersome.

  10. Are Minds Computable?, arXiv Next Article Bookmark and Share

    Abstract: This essay explores the limits of Turing machines concerning the modeling of minds and suggests alternatives to go beyond those limits.

  11. Editorial survey: swarm intelligence for data mining, Machine Learning Next Article Bookmark and Share

    Excerpt: This paper surveys the intersection of two fascinating and increasingly popular domains: swarm intelligence and data mining. Whereas data mining has been a popular academic topic for decades, swarm intelligence is a relatively new subfield of artificial intelligence which studies the emergent collective intelligence of groups of simple agents. It is based on social behavior that can be observed in nature, such as ant colonies, flocks of birds, fish schools and bee hives, where a number of individuals with limited capabilities are able to come to intelligent solutions for complex problems.

  12. Schedule and complex motion of shuttle bus induced by periodic inflow of passengers, Physics Letters A Next Article Bookmark and Share

    Abstract: We have studied the dynamic behavior of a bus in the shuttle bus transportation with a periodic inflow. A bus schedule is closely related to the dynamics. We present the modified circle map model for the dynamics of the shuttle bus. The motion of the shuttle bus depends on the loading parameter and the inflow period. The shuttle bus displays the periodic, quasi-periodic, and chaotic motions with varying both loading parameter and inflow rate.

  13. Do countries with lower self-citation rate produce higher-impact papers? Or, does humility pay?, Interciencia Next Article Bookmark and Share

    Abstract: Studying the 62 countries producing most papers reported in the SCImago data base in the period 1996-2008, it was found that countries with low per capita publication numbers show variable rates of self-citations and produce publications with lower citation impact. In contrast, countries with larger numbers of citations per paper have also high per capita publication numbers and their researchers appear to be humbler, showing lower rates of country and author self-citations. Notable exceptions are China, USA and Iran, which show abnormally high country self-citation rates, partially explained respectively by large populations, large total number of publications and language barriers. An increase of self-citation rates in almost all countries during the last decade, calls for exploring science policies that increase international scientific impact, such as more international cooperation, and science education with broader outlooks.

  14. Tumourâ€"host dynamics under radiotherapy, Chaos, Solitons & Fractals Next Article Bookmark and Share

    Abstract: Tumourâ€"host interaction is modelled by the Lotkaâ€"Volterra equations. Qualitative analysis and simulations show that this model reproduces all known states of development for tumours. Radiotherapy effect is introduced into the model by means of the linear-quadratic model and the periodic Dirac delta function. The evolution of the system under the action of radiotherapy is simulated and parameter space is obtained, from which certain threshold of effectiveness values for the frequency and applied doses are derived. A two-dimensional logistic map is derived from the modified Lotkaâ€"Volterra model and used to simulate the effectiveness of radiotherapy in different regimens of tumour development. The results show the possibility of achieving a successful treatment in each individual case by employing the correct therapeutic strategy.

  15. Cooperative game in a two-lane traffic flow, arXiv Next Article Bookmark and Share

    Abstract: We use cellular automata model to study the cooperation between cyclists. In the two-lane model, cyclists can change lanes. Even there is someone on the back they will take a cooperative attitude. It means that they will be in a same lattice. Simulation carried out under the open borders. Simulation results show that the density in a certain area appeared surge. When the (or) is constant and (or) changes in isometric, the distance between the curves are getting closer. If and close to the limit 1 or 0, a dramatic change has been observed in density profile.

  16. Smart Swarms of Bacteria-Inspired Agents with Performance Adaptable Interactions, PLoS Comput Biol Next Article Bookmark and Share

    Excerpt: Many groups of organisms, from colonies of bacteria and social insects through schools of fish and flocks of birds to herds of mammals exhibit advanced collective navigation. Identifying the minimal features of biologically-inspired interacting agents that can lead to emergence of “intelligent” like collective navigation and decision making is fundamental to our understanding of collective behavior, and is of great interest in artificial intelligence and robotics. Previous models of collective behavior of agents, which relied on static interactions of repulsion, orientation (alignment), and attraction, have shown the emergence of collective swarming. Here we show the advantage of performance adaptable interactions for navigation of groups in complex terrains.

    1. Dynamical modeling of collective behavior from pigeon flight data: flock cohesion and dispersion, arXiv Next Article Bookmark and Share

      Excerpt: Several models of flocking have been promoted based on simulations with qualitatively naturalistic behavior. In this paper we provide the first direct application of computational modeling methods to infer flocking behavior from experimental field data. We show that this approach is able to infer general rules for interaction, or lack of interaction, among members of a flock or, more generally, any community. Using experimental field measurements of homing pigeons in flight we demonstrate the existence of a basic distance dependent attraction/repulsion relationship and show that this rule is sufficient to explain collective behavior observed in nature.

  17. Indications of marine bioinvasion from network theory, Eur. Phys. J. B Next Article Bookmark and Share

    Excerpts: The transport of huge amounts of small aquatic organisms in the ballast tanks and at the hull of large cargo ships leads to ever increasing rates of marine bioinvasion. In this study, we apply a network theoretic approach to examine the introduction of invasive species into new ports by global shipping. (…) Our results reveal (…) that quick spread of invasive organisms between ports is likely. (…) Furthermore, from robustness analyses and the network’s percolation behaviour, we evaluate differences of onboard and in-port ballast water treatment, set them into context with previous studies and advise bioinvasion management strategies.

  18. Competition of individual and institutional punishments in spatial public goods games, arXiv Next Article Bookmark and Share

    Excerpts: We have studied the evolution of strategies in spatial public goods games where both individual (peer) and institutional (pool) punishments are present beside unconditional defector and cooperator strategies. (…) According to our numerical data peer punishers prevail and control the system behavior in a large segments of parameters while pool punishers can only survive in the limit of weak peer punishment when a rich variety of solutions is observed. Paradoxically, the two types of punishment may extinguish each other's impact resulting in the triumph of defectors. (…)

    2. Organic Computing - A Paradigm Shift for Complex Systems, Springer Basel Next Article Bookmark and Share

      Summary:
      Organic Computing has emerged as a challenging vision for future information processing systems. Its basis is the insight that we will increasingly be surrounded by and depend on large collections of autonomous systems, which are equipped with sensors and actuators, aware of their environment, communicating freely, and organising themselves in order to perform actions and services required by the users. These networks of intelligent systems surrounding us open fascinating application areas and at the same time bear the problem of their controllability. (...)

    3. Self-organising Software: From Natural to Artificial Adaptation, Springer Next Article Bookmark and Share

      Summary:
      Self-organisation, self-regulation, self-repair and self-maintenance are promising conceptual approaches for dealing with complex distributed interactive software and information-handling systems. Self-organising applications dynamically change their functionality and structure without direct user intervention, responding to changes in requirements and the environment. The editors developed this integrated book with three aims: to explain self-organisation concepts and principles, using clear definitions and a strong theoretical background; to examine how self-organising behaviour can be modelled, analysed and systematically engineered into agent behaviour; and to assess the types of problems that can be solved using self-organising multiagent systems.
