There are still heroes in science. They are recognized because the issues and problems they chose to study became the issues and problems of a major field of research. They are also recognized because their insights and solutions are the ones that are tested and evaluated when new ideas and technologies become available. In the field of plant evolutionary biology, the hero is George Ledyard Stebbins. His first scientific publi cation appeared in 1929 and has been followed by nearly 60 magnificent years of seminal ideas, proofs, and proposals that defined much of what was worth doing in plant biosystematics, evolution and biological conser vation. His energy, enthusiasm and good humor (widely shared at many congresses and symposia in the 'Singalongs with Stebbins') made him a wonderful teacher for both undergraduates and graduate students. He is the mentor of several generations of botanists, plant geneticists and evo lutionists. A brief biography and publication list were included in Topics in Plant Population Biology, edited by Otto T. Solbrig, Subodh Jain, George Johnson and Peter Raven (Columbia University Press, 1979) which resulted from a symposium held on the occasion of Ledyard Stebbins' 70th birthday. In this volume, population biology and physio logical ecology received major attention particularly in relation to plant form and function.

Publisher Description

Based on a comprehensive review of human and societal evolution the book develops an approach to conscious, self-guided evolution. In the course of the evolutionary journey of our species, there have been three seminal events. The first happened some seven million yeas ago, when our humanoid ancestors entered on the evolutionary scene. Their journey toward the second crucial event lasted over six million years when - as the greatest event of our evolutionary history - homo sapiens sapiens, started the revolutionary process of cultural evolution. Today, we have arrived at the threshold of the third major event, `the revolution of conscious evolution,' when it becomes our responsibility to enter into the evolutionary design space and guide the evolutionary journey of our species. The book tells the story of the first six million years of the journey in just enough detail to understand how evolution had worked in times when it was primarily biological, driven by natural selection. With the human revolution some fifty thousand years ago, with the emergence of self-reflective consciousness, the evolutionary process transformed from biological into cultural. From this point on, the book follows the journey with detailed attention, in order to learn how cultural evolution works. The book is organized in three parts. Part One commences with an exposition of a brief history of the evolutionary idea through time with a focus on a review of the science of general evolution and specifically social and societal evolution. Next, the book unfolds the `evolutionary story' of our species from the time when the first humanoids entered the evolutionary scene to our current era. Part Two develops a systems view of evolution, explores the ways and means of how evolution works, characterizes evolutionary consciousness and develops the idea of conscious evolution. Part Three builds upon the knowledge developed in the first two parts and sets forth the key conditions of conscious, self-guided evolution, elaborating the core condition, which is the acquisition of evolutionary competence through evolutionary learning. The focus of this part is on an approach to the design of evolutionary guidance systems that our families, neighborhoods, communities, organizations, social and societal systems can use to design the future they aspire to attain. The work is set aside from other statements in three important ways. It provides: (1) a comprehensive review of how evolution has worked with a focus on socio-cultural evolution, (2) an explanation of evolutionary consciousness and the conditions of engaging in conscious evolution, and (3) most significantly, it develops a detailed approach and a methodology to the design of evolutionary guidance systems.

Focuses on a range of fundamental issues in developing competence-base theory and in undertaking competence-based research intended to contribute to management theory development. This work assesses the areas in which restatements or extensions of competence theory may be needed or would be useful.

Praxiology deals with doing and working from the point of view of effectiveness. It has three components: analysis of concepts involving purposive actions; critique of models of action from the viewpoint of efficiency; and normative advisory aspects in recommendations for increasing human efficiency. This fourth volume of the Praxiology series is devoted to the very special topic of social agency. It focuses on two important praxiological concepts: rationality and preparation as preconditions for human action to be effective and efficient. The question of efficiency was raised by Anatol Rapoport over three decades ago in his lecture to the audience at the Praxiological Seminar in Warsaw in 1961. Social Agency begins with an article written by this same famous scholar on the topic of decision theory, "Social Dilemmas: A Historical Overview." Social dilemmas is the subject of the first part of this volume, a question related to studies on human action guided by two types of rationality: individual and collective rationality. The intersection of the two, in which individuals meet collectives, creates the situation in which social agency emerges, generating dilemmatic circumstances for the actors involved. The articles collected in the second part explore praxiological dimensions of education aimed toward the knowledge society, because of knowledge possessed and produced by educated persons. Chapters and contributors to volume 4 include: "Five Questions on the Research on Social Dilemmas" by Marek K. Mlicki; "Psychological Processes Underlying Cooperation in Social Dilemmas" by Paul A. M. Van Lange and David M. Messick; "Designing a System for Design Learning: Designers and/or Learners?" by Arne Collen; "Creating an Evolutionary Image of New Systems of Learning and Human Development" by Janet A. Khan; and "A Study Program Design in Retrospect" by Stig C. Holmberg. Social Agency continues the trend of original research done in a little-known, but important area. Social scientists, policymakers, and educators will benefit from this work.

The data of evolutionary biology have changed in a very radical way in recent years, the most significant input to this revolution being the advances made in developmental genetics. Another recent development is a noticeable shift away from extreme specialization in evolutionary biology. In this, we are perhaps to be reminded of George Gaylord Simpson's comments: "evolution is an incredibly complex but at the same time integrated and unitary process." The main objective of this book is to illustrate how natural adaptive systems evolve as a unity--with the particular objective of identifying and merging several special theories of evolution within the framework of a single general theory. The Evolution of Adaptive Systems provides an interdisciplinary overview of the general theory of evolution from the standpoint of the dynamic behavior of natural adaptive systems. The approach leads to a radically new fusion of the diverse disciplines of evolutionary biology, serving to resolve the considerable degree of conflict existing between different schools of contemporary thought. - The book is a timely volume written by a natural historian with a broad view of biology - The author draws examples from a large range of organisms from many different habitats and niches where interesting adaptations have evolved - Probes deeply into mechanisms of evolution such as developmental genetics, morphogenesis, chromosome structure, and cladogenesis - Clear definition of terms, with illustrations visualizing the main theoretical structures, and point-by-point summaries clearly stating the principal conclusions

In this original text/reference, Bela H. Banathy discusses a broad range of design approaches, models, methods, and tools, together with the theoretical and philosophical bases of social systems design. he explores the existing knowledge bases of systems design; introduces and integrates concepts from other fields that contribute to design thinking and practice; and thoroughly explains how competence in social systems design empowers people to direct their progress and create a truly participative democracy. Based on advanced learning theory and practice, the text's material is enhanced by helpful diagrams that illustrate novel concepts and problem sets that allow readers to apply these concepts.

The subject “Systems sciences and cybernetics” is the outcome of the convergence of a number of trends in a larger current of thought devoted to the growing complexity of (primarily social) objects and arising in response to the need for globalized treatment of such objects. This has been magnified by the proliferation and publication of all manner of quantitative scientific data on such objects, advances in the theories on their inter-relations, the enormous computational capacity provided by IT hardware and software and the critical revisiting of subject-object interaction, not to mention the urgent need to control the efficiency of complex systems, where “efficiency” is understood to mean the ability to find a solution to many social problems, including those posed on a planetary scale. The result has been the forging of a new, academically consolidated scientific trend going by the name of Systems Theory and Cybernetics, with a comprehensive, multi-disciplinary focus and therefore apt for understanding realities still regarded to be inescapably chaotic. This subject entry is subdivided into four sections. The first, an introduction to systemic theories, addresses the historic development of the most commonly used systemic approaches, from new concepts such as the so-called “geometry of thinking” or the systemic treatment of “non-systemic identities” to the taxonomic, entropic, axiological and ethical problems deriving from a general “systemic-cybernetic” conceit. Hence, the focus in this section is on the historic and philosophical aspects of the subject. Moreover, it may be asserted today that, beyond a shadow of a doubt, problems, in particular problems deriving from human interaction but in general any problem regardless of its nature, must be posed from a systemic perspective, for otherwise the obstacles to their solution are insurmountable. Reaching such a perspective requires taking at least the following well-known steps: a) statement of the problem from the determinant variables or phenomena; b) adoption of theoretical models showing the interrelationships among such variables; c) use of the maximum amount of – wherever possible quantitative – information available on each; d) placement of the set of variables in an environment that inevitably pre-determines the problem. That epistemology would explain the substantial development of the systemic-cybernetic approach in recent decades. The articles in the second section deal in particular with the different methodological approaches developed when confronting real problems, from issues that affect humanity as a whole to minor but specific questions arising in human organizations. Certain sub-themes are discussed by the various authors – always from a didactic vantage –, including: problem discovery and diagnosis and development of the respective critical theory; the design of ad hoc strategies and methodologies; the implementation of both qualitative (soft system methodologies) and formal and quantitative (such as the “General System Problem Solver” or the “axiological-operational” perspective) approaches; cross-disciplinary integration; and suitable methods for broaching psychological, cultural and socio-political dynamisms. The third section is devoted to cybernetics in the present dual meaning of the term: on the one hand, control of the effectiveness of communication and actions, and on the other, the processes of self-production of knowledge through reflection and the relationship between the observing subject and the observed object when the latter is also observer and the former observed. Known as “second order cybernetics”, this provides an avenue for rethinking the validity of knowledge, such as for instance when viewed through what is known as “bipolar feedback”: processes through which interactions create novelty, complexity and diversity. Finally, the fourth section centres around artificial and computational intelligence, addressing sub-themes such as “neural networks”, the “simulated annealing” that ranges from statistical thermodynamics to combinatory problem-solving, such as in the explanation of the role of adaptive systems, or when discussing the relationship between biological and computational intelligence.

Brings together considerations of the strategic relationship between technology and other resources, such as production capabilities, marketing prowess, finance and organisational culture.
