Evolution of self-replicating macromolecules through natural selection is a dynamically ordered process. Two concepts are introduced to describe the physical regularity of macromolecular evolution: sequence space and quasi-species. Natural selection means localization of a mutant distribution in sequence space. This localized distribution, called the quasi-species, is centered around a master sequence (or a degenerate set), that the biologist would call the wild-type. The self-ordering of such a system is an essential consequence of its formation through self-reproduction of its macromolecular consti tuents, a process that in the dynamical equations expresses itself by positive diagonal coefficients called selective values. The theory describes how population numbers of wild type and mutants are related to the distribution of selective values, that is to say, how value topography maps into population topography. For selectively (nearly) neutral mutants appearing in the quasi- species distribution, population numbers are greatly enhanced as compared to those of disadvantageous mutants, even more so in continuous domains of such selectively valuable mutants. As a consequence, mutants far distant from the wild type may occur because they are produced with the help of highly populated, less distant precursors. Since values are cohesively distributed, like mountains on earth, and since their positions are multiply connected in the high-dimensional sequence space, the overpopulation of (nearly) neural mutants provides guidance for the evolutionary process. Localization in sequence space, subject to a threshold in the fidelity of reproduction, is steadily challenged until an optimal state is reached. The model has been designed according to experimentally determined properties of self-replicating molecules. The conclusions reached from the theoretical models can be used to construct machines that provide optimal conditions for the evolution of functional macromolecules.

Agent-based computational modeling is changing the face of social science. In Generative Social Science, Joshua Epstein argues that this powerful, novel technique permits the social sciences to meet a fundamentally new standard of explanation, in which one "grows" the phenomenon of interest in an artificial society of interacting agents: heterogeneous, boundedly rational actors, represented as mathematical or software objects. After elaborating this notion of generative explanation in a pair of overarching foundational chapters, Epstein illustrates it with examples chosen from such far-flung fields as archaeology, civil conflict, the evolution of norms, epidemiology, retirement economics, spatial games, and organizational adaptation. In elegant chapter preludes, he explains how these widely diverse modeling studies support his sweeping case for generative explanation. This book represents a powerful consolidation of Epstein's interdisciplinary research activities in the decade since the publication of his and Robert Axtell's landmark volume, Growing Artificial Societies. Beautifully illustrated, Generative Social Science includes a CD that contains animated movies of core model runs, and programs allowing users to easily change assumptions and explore models, making it an invaluable text for courses in modeling at all levels.

These lectures develop simple models of complex social processes using nonlinear dynamics and mathematical biology. Dynamical analogies between seemingly disparate social and biological phenomena,revolutions and epidemics, arms races, and ecosystem dynamics,are revealed and exploited. Nonlinear Dynamics, Mathematical Biology, and Social Science invites social scientists to relax,in some cases abandon,the predominant assumption of perfectly informed utility maximization and explore social dynamics from such perspectives as epidemiology and predator-prey theory. The volume includes a concentrated course on nonlinear dynamical systems.

Azarya Polikarov was born in Sofia on October 9, 1921. Through the many stages of politics, economy, and culture in Bulgaria, he maintained his rational humanity and scientific curiosity. He has been a splendid teacher and an accomplished critical philosopher exploring the conceptual and historical vicis situdes of physics in modern times and also the science policies that favor or threaten human life in these decades. Equally and easily at home both within the Eastern and Central European countries and within the Western world. Polikarov is known as a collaborating genial colleague, a working scholar. not at all a visiting academic tourist. He understands the philosophy of science from within, in all its developments, from the classical beginnings through the great ages of Galilean, Newtonian. Maxwellian science. to the times of the stunning discoveries and imaginative theories of his beloved Einstein and Bohr of the twentieth century. Moreover, his understanding has come along with a deep knowledge of the scientific topics in themselves. Looking at our Appendix listing his principal publications, we see that Polikarov's public research career, after years of science teaching and popular science writing, began in the fifties in Bulgarian, Russian and German journals.

Social scientists, philosophers, and mathematicians have adapted evolutionary theory for use in a variety of disciplines for several decades, but until now historians have lagged behind. In The Return of Science, several distinguished historians join prominent scholars from a wide range of disciplines to debate the applications of evolutionary theory to cultural, social, economic, and political phenomena. The contributors offer original theoretical approaches and deal with issues such as the benefits, limits, and dangers of using evolutionary theory in the social sciences, the problem of defining units of evolution, the use of mathematics in historical study, and the appropriateness of chaos theory in historical study. Originally published as part of the journal History and Theory, these revised and updated essays are a valuable resource for historiographers.

This book examines sociobiology’s validity and significance, using the sociobiological theory of the evolution of mating and parenting as an example. It identifies and discusses the array of factors that determine sociobiology’s effort to become a science, providing a rare, balanced account—more critical than that of its advocates and more constructive than that of its critics. It sees a role for sociobiology in changing the way we understand the goals of evolutionary biology, the proper way to evaluate emerging sciences, and the deep structure of scientific theories. The book’s premise is that evolutionary biology would not be complete if it did not explain evolutionarily significant social facts about nonhumans and humans. It proposes that explanations should be evaluated in terms of their basis in underlying theories, research programs, and conceptual frameworks.

Debora Hammond's The Science of Synthesis explores the development of general systems theory and the individuals who gathered together around that idea to form the Society for General Systems Research. In examining the life and work of the SGSR's five founding members-Ludwig von Bertalanffy, Kenneth Boulding, Ralph Gerard, James Grier Miller, and Anatol Rapoport-Hammond traces the emergence of systems ideas across a broad range of disciplines in the mid-twentieth century. Both metaphor and framework, the systems concept as articulated by its earliest proponents highlights relationship and interconnectedness among the biological, ecological, social, psychological, and technological dimensions of our increasingly complex lives. Seeking to transcend the reductionism and mechanism of classical science-which they saw as limited by its focus on the discrete, component parts of reality-the general systems community hoped to complement this analytic approach with a more holistic orientation. As one of many systems traditions, the general systems group was specifically interested in fostering collaboration and integration among different disciplinary perspectives, with an emphasis on nurturing more participatory and truly democratic forms of social organization. The Science of Synthesis documents a unique episode in the history of modern thought, one that remains relevant today. This book will be of interest to historians of science, system thinkers, scholars and practitioners in the social sciences, management, organization development and related fields, as well as the general reader interested in the history of ideas that have shaped critical developments in the second half of the twentieth century.

Emergence and complexity refer to the appearance of higher-level properties and behaviours of a system that obviously comes from the collective dynamics of that system's components. These properties are not directly deducible from the lower-level motion of that system. Emergent properties are properties of the "whole'' that are not possessed by any of the individual parts making up that whole. Such phenomena exist in various domains and can be described, using complexity concepts and thematic knowledges. This book highlights complexity modelling through dynamical or behavioral systems. The pluridisciplinary purposes, developed along the chapters, are able to design links between a wide-range of fundamental and applicative Sciences. Developing such links - instead of focusing on specific and narrow researches - is characteristic of the Science of Complexity that we try to promote by this contribution.

Why do so many world-changing insights come from people with little or no related experience? Charles Darwin was a geologist when he proposed the theory of evolution. And it was an astronomer who finally explained what happened to the dinosaurs. Frans Johansson's The Medici Effect shows how breakthrough ideas most often occur when we bring concepts from one field into a new, unfamiliar territory and offers examples of how we can turn the ideas we discover into path-breaking innovations. Clayton M. Christensen, bestselling author of The Innovator's Dilemma, has described The Medici Effect as "one of the most insightful books about managing innovation I have ever read. Its assertion that breakthrough principles of creativity occur at novel intersections is an enduring principle of creativity that should guide innovators in every field." Now with a new preface and a discussion guide, and a foreword by Harvard Business School professor Teresa Amabile, The Medici Effect is a timeless classic that will help you reach your innovative peak.

When we first invited the group of distinguished scholars represented here to contribute to a new volume on Austrian economics, four themes were stressed: tensions, new directions, selectivity, and criticism. In this brief introduction we will explain why those themes were emphasized and thereby shed light on our intentions and aspirations for the volume. The subtitle "Tensions and New Directions" indicates clearly the intent of the volume desired. If we take the 1871 publication of Carl Menger's Principles of Economics (Grundsiitze der Volkswirthschaftslehre) as mark ing its birth, the Austrian tradition is now well over one hundred years old. The origins of the so-called "Austrian Revival" are more difficult to pinpoint precisely, but many would accept two decades as a reasonable estimate of its lifespan. In any case, since the mid-1970s several collections of articles written by Austrians have been published. The intent of these collections appeared to be to educate, persuade, and inspire various audiences. Uninformed readers needed to be told about the specifics of the Austrian position, to be shown how it differed from and improved upon its rivals. The initiated needed to be reassured that their commitment to a novel program was justified. As such, much of the recent Austrian literature has consisted either of exegetical accounts of the views of past figures, or of critical assessments of the positions of alternative research programs in economics from an Austrian perspective.

The theme of this book is the self-generation of information by the self-modification of systems. The author explains why biological and cognitive processes exhibit identity changes in the mathematical and logical sense. This concept is the basis of a new organizational principle which utilizes shifts of the internal semantic relations in systems. There are mathematical discussions of various classes of systems (Turing machines, input-output systems, synergetic systems, non-linear dynamics etc), which are contrasted with the author's new principle. The most important implications of this include a new conception on the nature of information and which also provides a new and coherent conceptual view of a wide class of natural systems. This book merits the attention of all philosophers and scientists concerned with the way we create reality in our mathematical representations of the world and the connection those representations have with the way things really are.

What will be the future of social science? Where exactly do we stand, and where do we go from here? What kinds of problems should we be addressing, with what kinds of approaches and arguments? In Cognitive Dimensions of Social Science, Mark Turner offers an answer to these pressing questions: social science is headed toward convergence with cognitive science. Together they will give us a new and better approach to the study of what human beings are, what human beings do, what kind of mind they have, and how that mind developed over the history of the species. Turner, one of the originators of the cognitive scientific theory of conceptual integration, here explores how the application of that theory enriches the social scientific study of meaning, culture, identity, reason, choice, judgment, decision, innovation, and invention. About fifty thousand years ago, humans made a spectacular advance: they became cognitively modern. This development made possible the invention of the vast range of knowledge, practices, and institutions that social scientists try to explain. For Turner, the anchor of all social science - anthropology, political science, sociology, economics - must be the study of the cognitively modern human mind. In this book, Turner moves the study of those extraordinary mental powers to the center of social scientific research and analysis.

Is the universe ultimately meaningful, ordered to an end of transcendental value? Or is it merely the product of random interactions in which organization emerges only locally and by chance and is conserved only so long as rare and improbable conditions prevail? There can, in fact, be no more important question, for on the resolution of this question depends the significance of all our worldly labors. The Ultimate Meaningfulness of the Universe represents a new departure in this debate, arguing that because it describes rather than explains the universe, mathematical physics is radically incapable of addressing this question. The book argues for a new scientific research paradigm that while incorporating and building on the description of the universe supplied by modern mathematical physics, goes beyond it in a restored discipline of teleological explanation. The book sketches applications in the physical, biological, and social domains, and shows that powerful evidence already points toward the ultimate meaningfulness of the universe.
