The nature of beauty , Prospect Excerpt: Art imitates life: René Magritte’s La condition humaine (1933): it’s only human to see nature as art Psychologists are taking a new interest in the evolutionary history of beauty. But there are still large unknowns. Evolutionary theory has had no problem explaining many—even most—of the things that give human beings pleasure: honey, orgasm, sunshine, lullabies, flower gardens. But, the closer we get to high art and beauty proper, the less easy it is to see how people’s attraction to it can be contributing to biological survival. If beauty were of relatively minor significance in human lives, we could push it to one side. But in reality it’s the opposite.

Biodiversity Conservation: Challenges Beyond 2010 , Science Abstract: The continued growth of human populations and of per capita consumption have resulted in unsustainable exploitation of Earth’s biological diversity, exacerbated by climate change, ocean acidification, and other anthropogenic environmental impacts. We argue that effective conservation of biodiversity is essential for human survival and the maintenance of ecosystem processes. Despite some conservation successes (especially at local scales) and increasing public and government interest in living sustainably, biodiversity continues to decline. Moving beyond 2010, successful conservation approaches need to be reinforced and adequately financed. In addition, however, more radical changes are required that recognize biodiversity as a global public good, that integrate biodiversity conservation into policies and decision frameworks for resource production and consumption, and that focus on wider institutional and societal changes to enable more effective implementation of policy. * [2] Biodiversity Conservation: Challenges Beyond 2010, Michael R.

Are large complex economic systems unstable? , arXiv Abstract: Although classical economic theory is based on the concept of stable equilibrium, real economic systems appear to be always out of equilibrium. Indeed, they share many of the dynamical features of other complex systems, e.g., ecological food-webs. We focus on the relation between increasing complexity of the economic network and its stability with respect to small perturbations in the dynamical variables associated with the constituent nodes. Inherent delays and multiple time-scales suggest that economic systems will be more likely to exhibit instabilities as their complexity is increased even though the speed at which transactions are conducted has increased many-fold through technological developments. Analogous to the birth of nonlinear dynamics from Poincare's work on the question of whether the solar system is stable, we suggest that similar theoretical developments may arise from efforts by econophysicists to understand the mechanisms by which instabilities arise in the economy. * [3] Are large complex economic systems unstable?, Sitabhra Sinha, 2010/09/06, arXiv:1009.0972 [3] http://arXiv.org/abs/1009.0972 _________________________________________________________________ 04.

The price of happiness , News@Nature Excerpt: And what exactly do we mean by happiness? That we laugh a lot, feel optimistic and secure in our lives, are serenely calm or deliriously hedonistic? In a recent 2008-09 Gallup poll of national happiness, the United States came fifth, and yet at the same time came 89th out of 151 in terms of 'least worry', and had the fifth-highest stress levels. It is hard to make sense of that: does happiness compensate for stress, or are they ineluctably conjoined? * [9] The price of happiness, Philip Ball, 2010/09/06, DOI: 10.1038/news.2010.447, News@Nature [9] http://www.nature.com/news/2010/100906/full/news.2010.447.html _________________________________________________________________ 06. Visualizing space–time dynamics in scaling systems , Complexity Abstract: The signature of scaling in human systems is the well-known power law whose key characteristic is that the size distributions of their objects display self-similarity in space and time. In many systems such as cities, firms, and high buildings used here as examples, power laws represent an approximation to the fat or heavy tails of their rank-size distributions, appearing stable in time with little change in their scaling over tens or even hundreds of years. However, when the detailed dynamics of how their ranks shift in time is examined, there is considerable volatility in such distributions. To explore this microvolatility, we introduce measures of rank shift over space and time and visualize size distributions using the idea of the “rank clock.” We illustrate this for populations of Italian towns between 1300 and 1861 and then compare this analysis with city-size distributions for the world from 430 B.C.E., the United States from 1790, Great Britain (England, Scotland, Wales) from 1901, and Israel from 1950. When we extend this analysis to the distribution of US firms from 1955 and high buildings in New York City and the world from 1909, we generate a rich portfolio of space–time dynamics that adds to our understanding of how different systems can display stability and regularity at the macro level in the face of considerable volatility at the micro. * [10] Visualizing space–time dynamics in scaling systems, Michael Batty, 2010/08/31, DOI: 10.1002/cplx.20342, Complexity Early View [10] http://dx.doi.org/10.1002/cplx.20342 _________________________________________________________________ 07. Chronicle of cybernetics pioneers , Nature Excerpt: [11] The Cybernetic Brain is the first book-length account of UK cybernetics pioneers. Working in parallel with Walter and his three-wheelers was Ross Ashby, whose early efforts were inspired by research in psychiatry. Later, Gordon Pask and Stafford Beer developed practical applications for cybernetics, ranging from architecture to management. Each of Pickering's characters is unconventional in personality, research topics and academic trajectory. In the early 1970s, for example, Beer applied his system to the development of a nationwide data network in Chile to control factory operations; later he used it to model cosmic consciousness. * [12] Chronicle of cybernetics pioneers, Rodney Brooks, 2010/09/09, DOI: 10.1038/467156a, Nature 467, 156–157 [11] http://www.amazon.com/gp/product/0226667898?ie=UTF8&tag=complexes-20&linkCode=as2&camp=1789&creative=9325&creativeASIN=0226667898 [12] http://dx.doi.org/10.1038/467156a _________________________________________________________________ 08. Wanted: a new breeding ground for antibiotics , Prospect Excerpt: t would be nice to be able to report that the much trumpeted “end of antibiotics” is just a slice of media alarmism. But it isn’t. The danger that just about all our existing antibiotics will soon be powerless against resistant bacteria, as recently claimed in the journal Lancet Infectious Diseases, is all too real. A paper in that journal reports the emergence and spread of strains of common pathogens, such as E coli and the pneumonia bug K pneumoniae, containing a gene that confers resistance even against current last-resort antibiotics (...) * [13] Wanted: a new breeding ground for antibiotics, Philip Ball, 2010/08/25, Prospect 174 [13] http://www.prospectmagazine.co.uk/2010/08/lab-report-5/ _________________________________________________________________ 09. Buzzwords on their way to a tipping-point: A view from the blogosphere , Complexity Abstract: “Buzzwords” are new words (i.e., neologisms) that enter the language and acquire great popularity as “fashion words.” To date, the dynamic aspect of buzzwords has not been the subject of a rigorous scientific analysis. In this study, we analyzed the appearance of buzzwords in the blogosphere and compared their dynamics to the one of nonpopular neologisms and well-established words. It was found that the growth rate of buzzwords is exponential and higher than that of the blogosphere. Moreover, we have identified general early warning signals for an approaching tipping point in the dynamics of buzzwords indicating that as fashion words they are on their way to a tipping-point of decline. The article presents these findings and others and concludes by presenting a model for studying the dynamics of new words entering the language. * [14] Buzzwords on their way to a tipping-point: A view from the blogosphere, Yair Neuman, Ophir Nave, Eran Dolev, 2010/09/07, DOI: 10.1002/cplx.20347, Complexity Early View [14] http://dx.doi.org/10.1002/cplx.20347 _________________________________________________________________ 09.01. The Spread of Behavior in an Online Social Network Experiment , Science Abstract: How do social networks affect the spread of behavior? A popular hypothesis states that networks with many clustered ties and a high degree of separation will be less effective for behavioral diffusion than networks in which locally redundant ties are rewired to provide shortcuts across the social space. A competing hypothesis argues that when behaviors require social reinforcement, a network with more clustering may be more advantageous, even if the network as a whole has a larger diameter. I investigated the effects of network structure on diffusion by studying the spread of health behavior through artificially structured online communities. Individual adoption was much more likely when participants received social reinforcement from multiple neighbors in the social network. The behavior spread farther and faster across clustered-lattice networks than across corresponding random networks. * [15] The Spread of Behavior in an Online Social Network Experiment, Damon Centola, 2010/09/03, DOI: 10.1126/science.1185231, Science Vol. 329. no. 5996, pp. 1194 - 1197 [15] http://dx.doi.org/10.1126/science.1185231 _________________________________________________________________ 10. Language Acquisition Meets Language Evolution , Cognitive Science Abstract: Recent research suggests that language evolution is a process of cultural change, in which linguistic structures are shaped through repeated cycles of learning and use by domain-general mechanisms. This paper draws out the implications of this viewpoint for understanding the problem of language acquisition, which is cast in a new, and much more tractable, form. In essence, the child faces a problem of induction, where the objective is to coordinate with others (C-induction), rather than to model the structure of the natural world (N-induction). We argue that, of the two, C-induction is dramatically easier. More broadly, we argue that understanding the acquisition of any cultural form, whether linguistic or otherwise, during development, requires considering the corresponding question of how that cultural form arose through processes of cultural evolution. This perspective helps resolve the “logical” problem of language acquisition and has far-reaching implications for evolutionary psychology. * [16] Language Acquisition Meets Language Evolution, Nick Chater, Morten H.

Spatial embedding and the structure of complex networks , Complexity Abstract: We review and discuss the structural consequences of embedding a random network within a metric space such that nodes distributed in this space tend to be connected to those nearby. We find that where the spatial distribution of nodes is maximally symmetrical some of the structural properties of the resulting networks are similar to those of random nonspatial networks. However, where the distribution of nodes is inhomogeneous in some way, this ceases to be the case, with consequences for the distribution of neighborhood sizes within the network, the correlation between the number of neighbors of connected nodes, and the way in which the largest connected component of the network grows as the density of edges is increased. We present an overview of these findings in an attempt to convey the ramifications of spatial embedding to those studying real-world complex systems. * [17] Spatial embedding and the structure of complex networks, S.

Fundamental limits on the suppression of molecular fluctuations , Nature Summary: Biological systems avoid molecular noise using feedback loops controlling RNA or protein synthesis, but these reactions rely on the stochastic birth and death of molecules. These authors use control and information theory to show that making a genetic network twice as accurate takes 16 times more signalling steps. Nature must therefore call on brute-force solutions to maintain accuracy, and hence does so only when noise suppression is absolutely vital. * [18] Fundamental limits on the suppression of molecular fluctuations, Ioannis Lestas, Glenn Vinnicombe & Johan Paulsson, 2010/09/09, DOI: 10.1038/nature09333, Nature 467 , 174–178 [18] http://dx.doi.org/10.1038/nature09333 _________________________________________________________________ 13. Cooperation enhanced by the ‘survival of the fittest’ rule in prisoner's dilemma games on complex networks , Journal of Theoretical Biology Excerpt: Prevalence of cooperation within groups of selfish individuals is puzzling in that it contradicts with the basic premise of natural selection, whereby we introduce a model of strategy evolution taking place on evolving networks based on Darwinian ‘survival of the fittest’ rule In the present work, players whose payoffs are below a certain threshold will be deleted and the same number of new nodes will be added to the network to maintain the constant system size. [...] Numerical results show that cooperators can obtain the biggest boost if the elimination threshold is fine-tuned. * [19] Cooperation enhanced by the ‘survival of the fittest’ rule in prisoner's dilemma games on complex networks, Zhang J , Zhang C , Chu T, November 2010, DOI: 10.1016/j.jtbi.2010.08.011, Journal of Theoretical Biology 267(1): 41-47 * Contributed by [20] Segismundo [19] http://dx.doi.org/10.1016/j.jtbi.2010.08.011 [20] http://segis.name _________________________________________________________________ 13.01. Evolutionary prisoners dilemma game with voluntary participation on regular lattices and scale-free networks , Physics Procedia Excerpt: The voluntary participation mechanism has been demonstrated as a natural extension to promote the cooperative behavior in evolutionary games. Apart from the cooperator strategy and defector strategy in the original Prisoner’s Dilemma Game (PDG), players can choose the additional loner strategy to refuse to participate and get some small but fixed income Q. We allow for voluntary participation in the evolutionary PDG on regular lattices and scale-free networks, and focus on the strategy density and the evolution behavior of the system. Simulation shows that the system behavior is sensitive to the population structure. * [21] Evolutionary prisoners dilemma game with voluntary participation on regular lattices and scale-free networks, Chen CL , Cao XB , Du WB , Rong ZH, August 2010, DOI: 10.1016/j.phpro.2010.07.028, Physics Procedia 3(5): 1845-1852 * Contributed by [22] Segismundo [21] http://dx.doi.org/10.1016/j.phpro.2010.07.028 [22] http://segis.name _________________________________________________________________ 14. A two level mutation-selection model of cultural evolution and diversity , Journal of Theoretical Biology Excerpt: Cultural evolution is a complex process that can happen at several levels. At the level of individuals in a population, each human bears a set of cultural traits that he or she can transmit to its offspring (vertical transmission) or to other members of his or her society (horizontal transmission). The relative frequency of a cultural trait in a population or society can thus increase or decrease with the relative reproductive success of its bearers (individual’s level) or the relative success of transmission (called the idea’s level). This article presents a mathematical model on the interplay between these two levels. The first aim of this article is to explore when cultural evolution is driven by the idea’s level, when it is driven by the individual’s level and when it is driven by both. * [23] A two level mutation-selection model of cultural evolution and diversity, Salazar-Ciudad I, November 2010, DOI: 10.1016/j.jtbi.2010.08.021, Journal of Theoretical Biology 267(2): 171-185 * Contributed by [24] Segismundo [23] http://dx.doi.org/10.1016/j.jtbi.2010.08.021 [24] http://segis.name _________________________________________________________________ 15. Two-lane traffic-flow model with an exact steady-state solution , arXiv Abstract: We propose a stochastic cellular-automaton model for two-lane traffic flow based on the misanthrope process in one dimension. The misanthrope process is a stochastic process allowing for an exact steady-state solution; hence we have an exact flow-density diagram for two lane traffic. In addition, we introduce two parameters that indicate respectively driver's driving-lane preference and passing-lane priority. Due to the additional parameters, the model shows a deviation of the density ratio for driving-lane use and a biased lane-efficiency in flow. Then, a mean-field approach explicitly describes the asymmetric flow by the hop rates, the driving-lane preference, and the passing-lane priority. Meanwhile, the simulation results are in good agreement with an observational data, and we thus estimate these parameters. We conclude that the proposed model successfully produces two-lane traffic flow particularly with the driving-lane preference and the passing-lane priority. * [25] Two-lane traffic-flow model with an exact steady-state solution, Masahiro Kanai, 2010/09/07, arXiv:1009.1204 [25] http://arXiv.org/abs/1009.1204 _________________________________________________________________ 16. A quantitative measure for the organization of a system, Part 1: A simple case , arXiv Abstract: Establishing an universal method to measure the organization of an universal system, will allow us to understand the mechanisms of functioning and organizing in general and enable us to design systems which will posses highest level of perfection. Attempts to measure organization have been done using information and entropy. The least action principle which is the basis of all branches of physics has been applied to a biotechnical system, ecosystem, chemical system and reliability theory to explain their functioning. Here we show that the amount of organization is inversely proportional to the physical amount of action in a system. We show the derivation of the expression for organization and apply it in a simple case. The significance of this result is that it will empower all of the natural and social sciences to quantify the organization in the systems that they are studying when it is applied to them. * [26] A quantitative measure for the organization of a system, Part 1: A simple case, Georgi Y Georgiev, 2010/09/06, arXiv:1009.1346 [26] http://arXiv.org/abs/1009.1346 _________________________________________________________________ 16.01.

The effect of gossip on social networks , Complexity Abstract: In this article, we develop a simple model for the effect of gossip spread on social network structure. We define gossip as information passed between two individuals A and B about a third individual C which affects the strengths of all three relationships: it strengthens A-B and weakens both B-C and A-C. We find, in both an analytic derivation and model simulations, that if gossip does not spread beyond simple triads, it destroys them but if gossip propagates through large dense clusters, it strengthens them. Additionally, our simulations show that the effect of gossip on network metrics (clustering coefficient, average-path-length, and sum-of-strengths) varies with network structure and average-node-degree. * [31] The effect of gossip on social networks, Allison K.

Parasite Replication and the Evolutionary Epidemiology of Parasite Virulence , PLoS ONE Excerpt: Parasite virulence evolution is shaped by both within-host and population-level processes yet the link between these differing scales of infection is often neglected.

Here, it is shown how the degree of relatedness among parasites together with epidemiological parameters such as pathogen yield and longevity influence the evolution of virulence. * [32] Parasite Replication and the Evolutionary Epidemiology of Parasite Virulence, Bonsall MB, August 2010, DOI: 10.1371/journal.pone.0012440, PLoS ONE 5(8): e12440 * Contributed by [33] Segismundo [32] http://dx.doi.org/10.1371/journal.pone.0012440 [33] http://segis.name _________________________________________________________________ 19.

If we know what technology will be imperative in 2030, the authors reason, what can we do now to influence future breakthroughs? Despite working in dissimilar fields, the experts called upon in the book - including Hans Blix (Head of the UN investigation in Iraq), Craig Venter (explorer of the human DNA), and Susan Greenfield (a leading world authority on the human brain), among many others - all emphasize the interconnectedness of our global networks in technology and communication, so tightly knit that the world's major conflicts are never isolated incidents.
