Buch. Condizione: Neu. Neuware - Research into the basic mechanisms of photosynthesis has a long and distinguished history and has consistently been at the forefront of science. The success of this research, particularly in recent years, suggests that photosynthesis may turn out to be the first complex biological system to have its structure, function, and regulation described in rigorous chemical terms at the atomic level. It is likely that such knowledge will help us to tackle perhaps the most vital problem facing mankind, namely our need for a continuous and nonpolluting source of energy. The benefit may come by providing a 'blueprint'for new technologies able to carry out efficient conversion of solar energy based on the principles of biological systems, and/or creating highly efficient 'energy crops' sufficiently hardy to grow in a wide range of environments. The former is likely to involve new developments in material sciences while the latter will call on the rapidly advancing techniques of genetic engineering. The contents of this volume review some of the most important developments which are a part of the drive towards the overall goal of obtaining the complete description of the photosynthetic processes at the molecular level. The topics covered have been carefully selected and represent the wide spectrum of the subject.…

Buch. Condizione: Neu. Neuware - This is the 17th volume in an annual series of reviews of research in organizational behaviour. This volume cover such topics as the development of a theory of timing, a framework for the integration of micro- and macro-organizational behaviour, and population-level learning.…

Buch. Condizione: Neu. Neuware - The book focuses on a conceptual flaw in contemporary artificial intelligence and cognitive science. Many people have discovered diverse manifestations and facets of this flaw, but the central conceptual impasse is at best only partially perceived. Its consequences, nevertheless, visit themselves asdistortions and failures of multiple research projects - and make impossible the ultimate aspirations of the fields.The impasse concerns a presupposition concerning the nature of representation - that all representation has the nature of encodings: encodingism. Encodings certainly exist, butencodingism is at root logically incoherent; any programmatic research predicted on it is doomed too distortion and ultimate failure.The impasse and its consequences - and steps away from that impasse - are explored in a large number of projects and approaches. These include SOAR, CYC, PDP, situated cognition, subsumption architecture robotics, and the frame problems - a general survey of the current research in AI and Cognitive Science emerges.Interactivism, an alternative model of representation, is proposed and examined. …
