The theory of tree languages, founded in the late Sixties and still active in the Seventies, was much less active during the Eighties. Now there is a simultaneous revival in several countries, with a number of significant results proved in the past five years. A large proportion of them appear in the present volume.

The editors of this volume suggested that the authors should write comprehensive half-survey papers. This collection is therefore useful for everyone interested in the theory of tree languages as it covers most of the recent questions which are not treated in the very few rather old standard books on the subject. Trees appear naturally in many chapters of computer science and each new property is likely to result in improvement of some computational solution of a real problem in handling logical formulae, data structures, programming languages on systems, algorithms etc. The point of view adopted here is to put emphasis on the properties themselves and their rigorous mathematical exposition rather than on the many possible applications.

This volume is a useful source of concepts and methods which may be applied successfully in many situations: its philosophy is very close to the whole philosophy of the ESPRIT Basic Research Actions and to that of the European Association for Theoretical Computer Science.

In the study of the computational structure of biological/robotic sensorimotor systems, distributed models have gained center stage in recent years, with a range of issues including self-organization, non-linear dynamics, field computing etc. This multidisciplinary research area is addressed here by a multidisciplinary team of contributors, who provide a balanced set of articulated presentations which include reviews, computational models, simulation studies, psychophysical, and neurophysiological experiments.

The book is divided into three parts, each characterized by a slightly different focus: in part I, the major theme concerns computational maps which typically model cortical areas, according to a view of the sensorimotor cortex as "geometric engine" and the site of "internal models" of external spaces. Part II also addresses problems of self-organization and field computing, but in a simpler computational architecture which, although lacking a specialized cortical machinery, can still behave in a very adaptive and surprising way by exploiting the interaction with the real world. Finally part III is focused on the motor control issues related to the physical properties of muscular actuators and the dynamic interactions with the world.

The reader will find different approaches on controversial issues, such as the role and nature of force fields, the need for internal representations, the nature of invariant commands, the vexing question about coordinate transformations, the distinction between hierachiacal and bi-directional modelling, and the influence of muscle stiffness.

Since the end of the sixties, Piagetian general theory with its inherent power of unification has gradually given way to a multitude of more specific models which is in evidence today. In this volume the authors concentrate on three perspectives namely cognitive, perceptuo-motor and neuropsychological development and attempt to coordinate these traditionally separated views. Good illustrations of these theoretical connections can be found in different chapters although the persistent isolation of these three domains still remains. However the authors believe efforts in developmental psychology must continue in the direction of domain interaction, for theoretical concepts as well as methodological tools.

The book provides a comprehensive state-of-the-art overview of current research on cognitive and applied aspects of eye movements. The contents include peer-reviewed chapters based on a selection of papers presented at the 11th European Conference on Eye Movements (Turku, Finland 2001), supplemented by invited contributions. The ECEM conference series brings together researchers from various disciplines with an interest to use eye-tracking to study perceptual and higher order cognitive functions.
The contents of the book faithfully reflect the scope and diversity of interest in eye-tracking as a fruitful tool both in basic and applied research. It consists of five sections: visual information processing and saccadic eye movements; empirical studies of reading and language production; computational models of eye movements in reading; eye-tracking as a tool to study human-computer interaction; and eye movement applications in media and communication research.
Each section is concluded by a commentary chapter by one of the leading authorities in the field. These commentaries discuss and integrate the contributions in the section and provide an expert view on the most significant present and future developments in the respective areas.
The book is a reference volume including a large body of new empirical work but also principal theoretical viewpoints of leading research groups in the field.

In recent years the most significant advances in carbohydrate research have been made in the knowledge of the structure and function of carbohydrates in the macromolecular state. This title addresses those areas of the subject in which the authors believe the most important work is being carried out.

This series is designed to provide a vehicle in which investigators, who have demonstrated a high degree of competence in some aspect of free radical chemistry, can present a particular area of interest. The series encompasses a wide variety of topics which are of current interest.

It has been said more than once in psychology that one person's effect is another person's error term. By minimising and occasionally ignoring individual and group variability cognitive psychology has yieled many fine achievements. However, when investigators are working with special populations, the subjects, and the unique nature of the sample, come into focus and become the goal in itself. For developmental psychologists, gerontologists and psychopathologists, research progresses with an eye on their target populations of study. Yet every good study in any of these domains inevitably has another dimension. Whenever a study is designed to turn a spotlight on a special population, the light is also shed on the mainstream from which the target deviates.

This book examines what we can learn about general and universal phenomena in cognition and its brain substrates from examining the odd, the rare, the transient, the exceptional and the abnormal.

"Advances in International Accounting" is a referred, academic research annual, that is devoted to publishing articles about advancements in the development of accounting and its related disciplines from an international perspective. This serial examines how these developments affect the financial reporting and disclosure practices, taxation, management accounting practices, and auditing of multinational corporations, as well as their effect on the education of professional accountants worldwide.
"Advances in International Accounting" welcomes traditional and alternative approaches, including theoretical research, empirical research, applied research, and cross-cultural studies.

This book presents what in our opinion constitutes the basis of the theory of the mu-calculus, considered as an algebraic system rather than a logic. We have wished to present the subject in a unified way, and in a form as general as possible. Therefore, our emphasis is on the generality of the fixed-point notation, and on the connections between mu-calculus, games, and automata, which we also explain in an algebraic way.
This book should be accessible for graduate or advanced undergraduate students both in mathematics and computer science. We have designed this book especially for researchers and students interested in logic in computer science, comuter aided verification, and general aspects of automata theory. We have aimed at gathering in a single place the fundamental results of the theory, that are currently very scattered in the literature, and often hardly accessible for interested readers.
The presentation is self-contained, except for the proof of the Mc-Naughton's Determinization Theorem (see, e.g., 97]. However, we suppose that the reader is already familiar with some basic automata theory and universal algebra. The references, credits, and suggestions for further reading are given at the end of each chapter.

The scope of service provided by professional accountants is influenced by legislation and case law as well as the dictates of a variety of government and private sector agencies; including State Boards of Accountancy, Academic Accreditation Bodies, the United States Securities and Exchange Commission, independent standard setting bodies such as the Federal Accounting Standards Advisory Board (US), the Financial Accounting Standards Board (US), and self-regulatory organizations such as State Societies of CPAs and the American Institute of Certified Public Accountants. There are equivalent and emerging national bodies that exist in most developed and developing countries, and further there are emerging global coordinating entities as well, which attempt to coordinate the activities among nations. It is important for academics, students, practitioners, regulators and researchers to consider, study and understand the role and relationship of such bodies with the practice and content of our discipline.
"Research in Accounting Regulation" is a refereed annual serial that seeks to publish high quality manuscripts, which address regulatory issues and policy affecting the practice of accountancy, broadly defined.

Advances in Accounting" was founded to provide a forum for discourse among and between academic and practising accountants on issues of significance to the future of the discipline. Emphasis was placed on original commentary and creative research that would substantively advance our understanding of behavioural and financial markets phenomena relevant to real world choices. Technology and global competition have brought tremendous changes in business and accounting. A wide array of unsolved questions continue to challenge a profession that defies definition and which is continuously reinventing itself. This volume focuses on questions of the "value added" by accounting information and audit services. Articles explore the important task of valuing corporate entities, and investigate challenges currently faced by auditors (client selection, pricing behaviour, and audit quality). Finally, contributors address the human side of career opportunities in the discipline and whether adequate human resources are flowing into the profession today. The theme of this collective effort is new solutions for new problems.

Hardbound. This volume of the Handbook is concerned particularly with the frequency side, or spectrum, approach to time series analysis. This approach involves essential use of sinusoids and bands of (angular) frequency, with Fourier transforms playing an important role. A principal activity is thinking of systems, their inputs, outputs, and behavior in sinusoidal terms. In many cases, the frequency side approach turns out to be simpler with respect to computational, mathematical, and statistical aspects. In the frequency approach, an assumption of stationarity is commonly made. However, the essential roles played by the techniques of complex demodulation and seasonal adjustment show that stationarity is far from being a necessary condition. Assumptions of Gaussianity and linearity are also commonly made and yet, as a variety of the papers illustrate, these assumptions are not necessary. This volume complements Handbook of Statistics 5: Time Series in the

The nature of global change in the Pacific Basin is poorly known compared to other parts of the world. Climate, Environment, and Society in the Pacific during the Last Millennium describes the climate changes that occurred in the Pacific during the last millennium and discusses how these changes controlled the broad evolution of human societies, typically filtered by the effects of changing sea level and storminess on food availability and interaction. Covering the entire period since AD 750 in the Pacific, this book describes the influences of climate change on environments and societies during the Medieval Warm Period and the Little Ice Age, focusing on the 100-year transition between these - a period of rapid change known as the AD 1300 Event.
* Discusses the societal effects of climate and sea-level change, as well as the evidence for externally-driven societal change
* Synthsizes how climate change has driven environmental change and societal change in the Pacific Basin
* Contains a comprehensive and up-to-date survey of the evidence for climate, environmental, and societal change, supported by a full list of references

Created in 1975, "LMT-Cachan" is a joint laboratory "ecole Normale Superieure de Cachan, Pierre & Marie Curie (Paris 6) University" and the French Research Council "CNRS" (Department of Engineering Sciences).

The Year 2000 marked the 25th anniversary of LMT. On this occasion, a series of lectures was organized in Cachan in September-October, 2000. This publication contains peer-reviewed proceedings of these lectures and is aimed to present engineers and scientists with an overview of the latest developments in the field of damage mechanics. The formulation of damage models and their identification procedures were discussed for a variety of materials.

for mathematicians who want to learn "what is going on" in some particular
field of research.

Bamboos constitute one of a few select categories of plants which are taxonomically related, very rich in species and of vital economic and ecological importance. Since the early 20th century the accepted number of species of bamboos, world wide, has tripled. However, until now information was scattered through numerous, often not easily available publications.

"The Bamboos of the World," is the first comprehensive (taxonomic as well as horticultural) reference work that provides basic information on bamboos world wide, whether they are wild or cultivated, well-known or rather unknown. The work, based on bamboo literature, facilitates access to further data by citation and a comprehensive bibliography. Among the main data included are botanical names with synonyms, and geographical distribution of genera and species, varieties with their distinctive characters, common bamboo names, plant introductions to the West, plant size and uses. The distribution of genera is mapped.

"The Bamboos of the World" presents a wealth of essential information in an accessible and structured manner. It gives the opportunity to check under what names, and where, relevant information on any bamboo can be found. For the researcher with management and development interests it provides a convenient means of basing bamboo resource on a sound understanding of generic and species relationships, with names that appear in earlier literature put into context. The work should prove to be invaluable for those interested in the morphology, taxonomy, distribution and cultivation of bamboos. It should support botanical, forestry, horticultural and ecological research, training and resource management.

Making Sense of Inner Sense
"'Terra cognita'" is "terra incognita." It is difficult to find someone not taken abackand fascinated by the incomprehensible but indisputable fact: there are material systems which are aware of themselves. Consciousness is self-cognizing code. During "homo sapiens's" relentness and often frustrated search for self-understanding various theories of consciousness have been and continue to be proposed. However, it remains unclear whether and at what level the problems of consciousness and intelligent thought can be resolved. Science's greatest challenge is to answer the fundamental question: what precisely does a cognitive state amount to in physical terms?
Albert Einstein insisted that the fundamental ideas of science are essentially simple and can be expressed in a language comprehensible to everyone. When one thinks about the complexities which present themselves in modern physics and even more so in the physics of life, one may wonder whether Einstein really meant what he said. Are we to consider the fundamental problem of the mind, whose understanding seems to lie outside the limits of the mind, to be essentially simple too? Knowledge is neither automatic nor universally deductive. Great new ideas are typically counterintuitive and outrageous, and connecting them by simple logical steps to existing knowledge is often a hard undertaking. The notion of a tensor was needed to provide the general theory of relativity; the notion of entropy had to be developed before we could get full insight into the laws of thermodynamics; the notice of information bit is crucial for communication theory, just as the concept of a Turing machine is instrumental in the deep understanding of a computer. To understand something, consciousness must reach an adequate intellectual level, even more so in order to understand itself. Reality is full of unending mysteries, the true explanation of which requires very technical knowledge, often involving notions not given directly to intuition. Even though the entire content and the results of this study are contained in the eight pages of the mathematical abstract, it would be unrealistic and impractical to suggest that anyone can gain full insight into the theory that presented here after just reading abstract.
In our quest for knowledge we are exploring the remotest areas of the macrocosm and probing the invisible particles of the microcosm, from tiny neutrinos and strange quarks to black holes and the Big Bang. But the greatest mystery is very close to home: the greatest mystery is human consciousness. The question before us is whether the logical brain has evolved to a conceptual level where it is able to understand itself.
