Buch. Condición: Neu. Neuware - We are now witness to the waning years of the 1900s. Soon, we shall embark upon a bold journey into the uncharted territory of the twenty-first of various persuasions have speculated as to what the century. Futurists oncoming decades might bestow upon us. Not surprising, most predictions are closely tied to advances in technology, especially in astrophysiCS, biochemistry, electronics, and genetics. But what about the economic system Whatever happens, forces have undoubtedly already been set in motion which will mold (or remold) the structure and character of American capitalism. American capitalism has been, is, and will undoubtedly continue to be a system in transition. Technology perennially changes, albeit at a faster or slower pace sometimes than others, and society's institutions continually adjust to these technological changes. Such adjustments alter the character of our politico-economic system when statutes are enacted, court decisions rendered, administrative agency rules promulgated, and cultural mores realigned to supplant old ones. Other adaptations are brought about when small-group collective action is successful in causing a special status of privilege to be conferred on some members of society, but restrictions to be levied on others.

Buch. Condición: Neu. Neuware - It gives me great pleasure to offer this foreword to the present work of my admired friend and respected colleague Ota Weinberger. Apart from the essays of his which were published in our joint work An Institutional Theory of Law: New Approaches to Legal Positivism in 1986, relatively little of Wein berger's work is available in English. This is the more to be regretted, since his is work of particular interest to jurists of the English-speaking world both in view of its origins and in respect of its content As to its origins, Weinberger war reared as a student of the Pure Theory of Law, a theory which in its Kelsenian form has aroused very great interest and has had considerable influence among anglophoone scholars -perhaps even more than in the Germanic countries. Less well known is the fact that the Pure Theory itself divided into two schools, that of Vienna and that of Brno. It was in the Brno school of Frantisek Weyr that Weinberger's legal theory found its early formation, and perhaps from that early influence one can trace his continuing insistence on the dual character of legal norms -both as genuinely normative and yet at the same time having real social existence.

Buch. Condición: Neu. Neuware - The 10th International Workshop on Maximum Entropy and Bayesian Methods, MaxEnt 90, was held in Laramie, Wyoming from 30 July to 3 August 1990. This volume contains the scientific presentations given at that meeting. This series of workshops originated in Laramie in 1981, where the first three of what were to become annual workshops were held. The fourth meeting was held in Calgary. the fifth in Laramie, the sixth and seventh in Seattle, the eighth in Cambridge, England, and the ninth at Hanover, New Hampshire. It is most appropriate that the tenth workshop, occurring in the centennial year of Wyoming's statehood, was once again held in Laramie. The original purpose of these workshops was twofold. The first was to bring together workers from diverse fields of scientific research who individually had been using either some form of the maximum entropy method for treating ill-posed problems or the more general Bayesian analysis, but who, because of the narrow focus that intra-disciplinary work tends to impose upon most of us, might be unaware of progress being made by others using these same techniques in other areas. The second was to introduce to those who were somewhat aware of maximum entropy and Bayesian analysis and wanted to learn more, the foundations, the gestalt, and the power of these analyses. To further the first of these ends, presenters at these workshops have included workers from area. s as varied as astronomy, economics, environmenta.

Buch. Condición: Neu. Neuware - Many agricultural crops worldwide, especially in semi-arid climates, suffer from iron deficiencies. Among plants sensitive to iron deficiency are apples, avocado, bananas, barley, beans, citrus, cotton, grapes, peanuts, pecans, potatoes, sorghum, soybeans, and numerous ornamental plants. Deficiencies are usually recognized by chlorotic, in new leaves and are typically found among sensitive crops grown in calcareous or yellowed, interveinal areas soils which cover over 30% of the earth's land surface. Iron deficiency may lead, in extreme cases, to complete crop failure. In intensive agriculture on calcareous soils, iron often becomes a major limiting nutrient for optimal crop production, thus, correction of iron deficiency is required. Various chemicals and practices are available. They are, however, costly and do not always result in a complete remedy of the deficiency. Crucial questions relative to the cost-benefit equation such as the recovery rate of plants and the long-term fertilizing effect have not yet been resolved. The complexity of iron nutrition problems requires an understanding of the chemistry of iron oxides in soils, of the chemistry of both natural and synthetic chelates, of rhizosphere microbiology and biochemistry, and of the physiological involvement of the plant in iron uptake and transport.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Using panel data of individual firms drawn from French surveys, a structural analysis is developed to study the formation of production plans and the rationality of expectations. The production decision of a firm is defined as the optimal solution of a dynamic stochastic optimization problem. The empirical work amounts to recovering the structural parameters characterizing the model of the firm from estimates of the derived decision rule. The preceding analysis of production plans is based on the assumption that firms are rational. To justify this assumption, direct tests offer evidence that the Rational Expectations Hypothesis may not be rejected for quantity variables. 248 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The development of database technology has currently reached the stage of deductive database systems which use Horn clauses for defining relations. An important characteristic of these systems is the clear separation of logic and control. However, the programmer cannot affect the control part of a deductive database system. To eliminate this deficiency, this monograph presents a so-called expert deductive database system that allows explicit control of the deduction process. The system consists of an object-level describing the logical aspects of a problem and of a meta-level that contains application-specific control information affecting the object-level deduction process. For example, object-level rules can be disregarded, and some tuples deduced at the object-level can be preferred to others. Besides the architecture of this system, the book also identifies some important possibilities of deduction control which are explained by characteristic examples. 168 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -by Noll, then scantly known, at the Carnegie Institute of Technology. An invita tional meeting on visco-elasticity in the following April at Lancaster, Pennsyl vania, brought Coleman and Noll together. In those days a person went to a meet ing so as to learn from a few competent lectures without having to be himself one more 'invited speaker' or to listen to many multiples of ten minutes of trivial trash. Ericksen lectured on 'laminar shear flows' of incompressible, Rivlin-Erick sen fluids. That class of flows contains all those for which Rivlin and others had obtained exact solutions. Ericksen's paper, with Criminale & Filbey as co-authors, was to appear soon in Volume 1 of the Archive. At the meeting, Coleman and Noll found that they had similar views on thermodynamics. The rheologists there, like those we had encountered elsewhere, told us that classical thermodynamics was a complete, closed, perfect science, all in Gibbs's paper, and they laughed at us. We laughed at them, but silently, for we had read fundamental parts of Gibbs's work, especially that on the isothermal and isentropic theories of three-dimensional elasticity, which, surely, the rheologists could not understand. We knew also the basic inequality for increase of entropy asserted by Duhem (1901) and in 'The Mechanical Foundations' (1952) called 'the Clausius-Duhem inequality' (Eq. (28. 5', from which Eckart (1940) had drawn consequences by guessing the signs oftwo terms ('Mechanical Foundations', text following Eq. (31. 1'. 592 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This book is intended for engineers, computer scientists, managers and all those concerned with computer graphics, computer-aided design and computer-aided manufacture. While it is primarily intended for students, lecturers and teachers, it will also appeal to those practising in industry. Its emphasis on applications will make it easier for those not currently concerned with computers to under stand the basic concepts of computer-aided graphics and design. In a previous text (Engineering Drawing and Computer Graphics), two of the authors introduced the basic principles of engineering drawing and showed how these were related to the fundamentals of computer graphics. In this new text, the authors attempt to give a basic understanding of the principles of computer graphics and to show how these affect the process of engineering drawing. This text therefore assumes that the reader already has a basic knowl edge of engineering drawing, and aims to help develop that understanding through the medium of computer graphics and by the use of a number of computer graphics exercises. The text starts by giving an overview of the basics of hardware and software for CAD and then shows how these principles are applied, in practice, in the use of a number of graphics packages of different levels of complexity. The use of a graphical database and the implications for computer-aided design and manufacture are also discussed. This book is unique in its applications approach to computer graphics. 352 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -This thesis deals with timing and sizing decisions for production lots, and more precisely, with mathematical models to support optimal tim ing and sizing decisions. These models are called lotsizing models. They are characterized by the fact that production lots are determined based on a trade-offbetween production costs and customer service. Production costs can be categorized as basic production costs, which consist of material costs, labour costs, machine startup costs and over head costs, and inventory related costs, which include costs of capital tied up in inventory, insurances and taxes. Customer service is the capability of the firm to deliver to their clients the products in the quantity they ordered at the agreed upon time and place. The costs of realizing a certain service level are usuaIly very dif ficult to convert into money. They include costs of expediting, loss of customer goodwill, and loss of sales revenues resulting from the short age situation. 168 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -Marketing communications is a subject which has become popular in both marketing and public relations circles, but sometimes with different parameters. There are those who prefer to confine marketing communications to promotional activities, which is mostly an academic point of view, and there are those who see the subject in broader terms, embracing every form of communication used in marketing, which is how the subject is practised in the business world. While the author has long experience as a teacher and examiner, he also continues to be a professional practitioner. Consequently, the book aims to serve those concerned with both the academic and the professional in terpreta tions of marketing comm unica tions. I t is of course hoped that those who adopt the academic approach to the subject will eventually acknowledge that there is more to marketing communi cations than advertising, sales promotion, selling, marketing research and public relations. It is also necessary to realise that public relations embraces much more than the 'publicity' in the 4Ps promotion box. Without wishing to be contentious, this broad approach is proposed so that communications of all kinds throughout the marketing strategy can have maximum effect. Very little has been published on this subject, and the book is therefore a pioneer attempt to establish the practical parameters of modern marketing communications. There are so many broad and narrow interpretations of marketing communications, but it is hoped that this book will be useful to teachers, students and practitioners of the subject. 252 pp. Englisch.

Taschenbuch. Condición: Neu. This item is printed on demand - it takes 3-4 days longer - Neuware -The importance of industrial chemistry Chemistry is a challenging and interesting subject for academic study. Its principles and ideas are used to produce the chemicals from which all manner of materials and eventually consumer products are manufactured. The diversity of examples is enormous, ranging from cement to iron and steel, and on to modern plastics which are so widely used in the packaging of consumer goods and in the manufacture of household items. Indeed life as we know it today could not exist without the chemical industry. Its contribution to the saving of lives and relief of suffering is immeasurable; synthetic drugs such as those which lower blood pressure (e. g. /3-blockers), attack bacterial and viral infections (e. g. antibiotics such as the penicillins and cephalosporins) and replace vital natural chemicals which the body is not producing due to some malfunction (e. g. insulin, some vitamins), are particularly noteworthy in this respect. Effect chemicals also clearly make an impact on our everyday lives. Two examples are the use of polytetrafluoroethylene (polytetrafluoroethene Teflon or Fluon) to provide a non-stick surface coating for cooking utensils, and silicones which are used to ease the discharge of bread from baking tins. It should also be noted that the chemical industry's activities have an influence on all other industries, either in terms of providing raw materials or chemicals for quality control analyses and to improve operation, and to treat boiler water, cooling water and effiuents. 436 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -TAPSOFT '91 is the Fourth International Joint Conference on Theory and Practice of Software Development. It was held in Brighton, April 8-12, 1991, and was organized by the Department of Computing, Imperial College, London. The proceedings of TAPSOFT '91 are organized into three parts: - Colloquium on Trees in Algebra and Programming (CAAP); - Advances in Distributed Computing (ADC); - Colloquium on Combining Paradigms for Software Development (CCPSD). The first part (CAAP) is contained in Vol. 1, the other two parts constitute Vol. 2. CAAP '91 focuses on the following topics: - Logical, algebraic and combinatorial properties of discrete structures (strings, trees, graphs, etc.), including the theory of formal languages considered in the broad sense as that of sets of discrete structures and the theory of rewriting systems over them. - Application of discrete structures in computer science: syntax and semantics of programming languages, operational semantics, logic programming, algorithms and data structures, complexity of algorithms and implementation aspects, proof techniques for nonnumerical algorithms, formal specifications, and visualization of structured objects. The ADC talks by distinguished invited speakers survey current developments in distributed computing, including the integration of different paradigms for concurrency, algebraic, logical and operational foundations, and applications to software engineering and formal methods. The CCPSD papers address aspects of the trend in software engineering towards unification and synthesis combining theory and practice, and merging hitherto diverse approaches. 468 pp. Englisch.

This item is printed on demand - it takes 3-4 days longer - Neuware -A few years ago, a motivation for organizing one more IAU Symposium on star for mation in Grenoble, was the anticipated completion of the IRAM interferometer on the Plateau de Bures, close to Grenoble. This choice was also a sort of late celebration of the genius of Joseph Fourier, born in Grenoble, whose work is the very fondation of in terferometry. At the time when we finally announced the advent of this conference, the first reactions we got from the community were expressions of saturation and even reject, the Symposium being unfortunately scheduled almost simultaneously as two other major meetings on closely related topics, and sponsored by different organizations. A wave of disappointment then reached the organizers. Some of us were enthusiastic enough to help the others overcome their discouragement. Let them be thanked here. There was, indeed, a deeper motivation for organizing this conference. It was to trigger the meeting and communication of physicists and astrophysicists since many of the difficulties met now in understanding the physics of the interstellar medium and its evolution toward star formation are common to several, if not most, other fields of physics. They are assigned to one origin: complexity. 584 pp. Englisch.
