Dawkins Biomorph Viewer

      Biomorph Viewer allows you to intervene directly on the genome. Click one of the genes in the last square and move the mouse, the corresponding genes will be automatically modified. If, during this process, the mouse moves from the box of a gene to another one, the second gene will also be modified. Notice that in gene representation, the circle shows the default basic size.

      Like for all programs dealing with artificial life, the use of Biomorph Viewer needs efforts. Take time to test the different forms, use random function to get original starting data (you may reduce the number of junctions after selecting random biomorphs). Play on the dynamic modifications of the genome (try to make the biomorph dance on the music you’re listening to, it can be quite funny !) Approaching artificial life may not appear immediately obvious. Take time to explore and understand and you’ll dive into a fascinating universe !

Thinking about the liquidity trap

      THINKING ABOUT THE LIQUIDITY TRAP

      Paul Krugman

      December 1999

      We live in the Age of the Central Banker – an era in which Greenspan, Duisenberg, and Hayami are household words, in which monetary policy is generally believed to be so effective that it cannot safely be left in the hands of politicians who might use it to their advantage. Through much of the world, quasi-independent central banks are now entrusted with the job of steering economies between the rocks of inflation and the whirlpool of deflation. Their judgement is often questioned, but their power is not.

      It is therefore ironic as well as unnerving that precisely at this moment, when we have all become sort-of monetarists, the long-scorned Keynesian challenge to monetary policy – the claim that it is ineffective at recession-fighting, because you can%u2019t push on a string – has reemerged as a real issue. So far only Japan has actually found itself in liquidity-trap conditions, but if it has happened once it can happen again, and if it can happen here it presumably can happen elsewhere. So even if Japan does eventually emerge from its slump, the question of how it became trapped and what to do about it remains a pressing one.

      The Science of Self-Organizing Systems

      The scientific study of self-organizing systems is relatively new, although questions about how organization arises have of course been raised since ancient times. The forms we identify around us are only a small sub-set of those theoretically possible. So why don’t we see more variety ? To answer such a question is the reason why we study self-organization.

      Many natural systems show organization (e.g. galaxies, planets, chemical compounds, cells, organisms and societies). Traditional scientific fields attempt to explain these features by referencing the micro properties or laws applicable to their component parts, for example gravitation or chemical bonds. Yet we can also approach the subject in a very different way, looking instead for system properties applicable to all such collections of parts, regardless of size or nature. It is here that modern computers prove essential, allowing us to investigate the dynamic changes that occur over vast numbers of time steps and with a large numbers of initial options.

      Studying nature requires timescales appropriate for the natural system, and this restricts our studies to identifiable qualities that are easily reproduced, precluding investigations involving the full range of possibilities that may be encountered. However, mathematics deals easily with generalised and abstract systems and produces theorems applicable to all possible members of a class of systems. By creating mathematical models, and running computer simulations, we are able to quickly explore large numbers of possible starting positions and to analyse the common features that result. Even small systems have almost infinite initial options, so even with the fastest computer currently available, we usually can only sample the possibility space. Yet this is often enough for us to discover interesting properties that can then be tested against real systems, thus generating new theories applicable to complex systems and their spontaneous organization.

Agent-Based Computational Economics (Tesfatsion)

      Agent-based computational economics (ACE) is the computational study of economic processes modeled as dynamic systems of interacting agents. Here “agent” refers broadly to a bundle of data and behavioral methods representing an entity constituting part of a computationally constructed world.

      Examples of possible agents include individuals (e.g., consumers, producers), social groupings (e.g., families, firms, communities, government agencies), institutions (e.g., markets, regulatory systems), biological entities (e.g., crops, livestock, forests), and physical entities (e.g., infrastructure, weather, and geographical regions). Thus, agents can range from active data-gathering decision makers with sophisticated learning capabilities to passive world features with no cognitive function. Moreover, agents can be composed of other agents, permitting hierarchical constructions.

PrudentBear.com – The One-Stop Shop for the Bear Case

      A debt-deflation induced depression would have a dominating influence on the US economy over the next ten years. A crucial factor in the future performance of the US economy is the housing market. A crash in the over-inflated housing market has the potential to drive the US economy into a depression. A depression in the world’s largest economy has the potential to plunge the world into a similar situation, especially in light of the struggling Japanese and German economies. In this, the worst-case scenario for the US, ten years might not be enough for the economy to see a recovery.

      The scenario above is likely, but it is not the only possibility. The Federal Reserve is well aware of the potential dangers. Although avoiding disaster may be beyond the Federal Reserve’s capabilities and economic realities, avoiding a depression would prove the resilience of the US economy to economic shocks.
      Speculative bubbles and the consequent crashes are an economic reality, perhaps the awareness of Fisher’s model has helped economic policy makers and intelligent businessmen to create an economy and companies which are not immune to the effects of economic shocks, but are more resilient to them.”

      This would kinda tie in with kondratieff’s long wave as well, sometimes the more you prop something up the worse it gets. eeek!

WHAT IS EVOLUTIONARY WORLD POLITICS

      WHAT IS EVOLUTIONARY WORLD POLITICS?

      Evolutionary world politics is the employment of evolutionary theory in the study of long-term change in world-wide political arrangements.

      World-wide political arrangements are those stable patterns of human behavior that are institutionalized at global and other levels of the organization of the human species. These include city-states and empires, global wars and alliances, the nation-state system, global leadership and world organization. The evolution of these structures over historical time is at the core of this field but world politics is not a stand-alone subject and needs at the same time to be seen as systematically related to, in particular, changes in economic institutions, such as industrial sectors and trade regimes, to social processes such as democratization, and to movements of world opinion.”

      Until we learn to stop only talking about politics using our erstwhile masters’ terms and concepts we will continue to propogate and feed the system, which is as an enimical and false one as fuedalism or any other, rather than be free of it, and progress to something genuinly sustainable and egalitarian.

Synergy, Cybernetics, and the Evolution of Politics

🙂

      The tumultuous political events of the past decade or so have, among other things, compelled political scientists to rethink some of their long established concepts and analytical constructs. One example is “political development,” a term which has traditionally been associated with the optimistic post-World War Two scenario in which “developing nations” were said to be following “industrial societies” into a final stage of “post-industrial” history that would, presumably, be permanently embalmed in stable democracy and some variant of the traditional “balance of power” — or terror. That smug scenario has been deflated by a sequence of events which suggest that the modern nation-state may itself be a transient phenomenon, a stepping-stone on the way to something larger, or smaller, or both — or perhaps neither.”

      rethinking.
