Internationally, there is increasing research and interest in the processes of the production and reception of texts for specific purposes and in the historical development of genres and registers within Languages for Specific Purposes (LSP), psycholinguistics, sociolinguistics, anthropology and the sociology of science. Studies of professional communication have traditionally been biased towards the written medium and have been carried out with little, if any, connection to LSP. Disciplinary boundaries and interest groupings have thus kept these different approaches to the study of professional communication and interaction separate. The editors of this volume unite these different perspectives and approaches and bring together recent research from linguistics, sociolinguistics, ethnography of communication, anthropology and sociology to provide an up-to-date analysis of different varieties of professional discourse and their historical development. Chapters written by leading exponents in the field deal with the core theoretical issue of how language, written genres and spoken discourse are constructed as a successive and continuous interplay between language and social realities. The volume includes chapters on the moral construction of discourse in the social care profession, the discourse of dispute negotiation, narrative accounts in clinical research, doctor-patient interaction, legal and other kinds of institutional discourse. A key text for students of applied linguistics and sociolinguistics at both advanced, undergraduate and MA levels.
Artificial neural networks possess several properties that make them particularly attractive for applications to modelling and control of complex non-linear systems. Among these properties are their universal approximation ability, their parallel network structure and the availability of on- and off-line learning methods for the interconnection weights. However, dynamic models that contain neural network architectures might be highly non-linear and difficult to analyse as a result. Artificial Neural Networks for Modelling and Control of Non-Linear Systems investigates the subject from a system theoretical point of view. However the mathematical theory that is required from the reader is limited to matrix calculus, basic analysis, differential equations and basic linear system theory. No preliminary knowledge of neural networks is explicitly required. The book presents both classical and novel network architectures and learning algorithms for modelling and control. Topics include non-linear system identification, neural optimal control, top-down model based neural control design and stability analysis of neural control systems. A major contribution of this book is to introduce NLq Theory as an extension towards modern control theory, in order to analyze and synthesize non-linear systems that contain linear together with static non-linear operators that satisfy a sector condition: neural state space control systems are an example. Moreover, it turns out that NLq Theory is unifying with respect to many problems arising in neural networks, systems and control. Examples show that complex non-linear systems can be modelled and controlled within NLq theory, including mastering chaos. The didactic flavor of this book makes it suitable for use as a text for a course on Neural Networks. In addition, researchers and designers will find many important new techniques, in particular NLq emTheory, that have applications in control theory, system theory, circuit theory and Time Series Analysis.
Has the neuromuscular junction been over-exposed or is it perhaps already a closed book? I asked myself this at a recent International Congress when an American colleague complained that the Journal of Physiology had articles on nothing but the neuromuscular junction, while another colleague asked why I was editing a volume on a subject about which everything was already known. It is worrying to think that these views may be shared by other people. I hope that this volume will convince my two colleagues and other readers that the neuromuscular junction is very much alive and continues to attract the interest of many workers from a variety of fields; strange as it may seem, the synapse between a motor nerve ending and muscle fibre, with its relatively simple architecture, is one of the most inter esting sites in the body-I do hope we have done it justice. The various chapters of this volume present a cross section of knowledge as viewed by a group of 13 individuals, actively engaged in research. Multi-author volumes such as this are frequently criticised on the grounds that chapters or sec tions overlap. I believe that such criticium is only valid where the overlap is repetitious. Where it results in the reader having available discussions of material from differing stand-points, overlap becomes a valuable feature of this type of publication.
This graduate-level text's primary objective is to demonstrate the expression of the equations of the various branches of mathematical physics in the succinct and elegant form of variational principles (and thereby illuminate their interrelationship). Its related intentions are to show how variational principles may be employed to determine the discrete eigenvalues for stationary state problems and to illustrate how to find the values of quantities (such as the phase shifts) that arise in the theory of scattering. Chapter-by-chapter treatment consists of analytical dynamics; optics, wave mechanics, and quantum mechanics; field equations; eigenvalue problems; and scattering theory. 1966 edition. Bibliography.

Semiconductor Heterojunctions investigates various aspects of semiconductor heterojunctions. Topics covered include the theory of heterojunctions and their energy band profiles, electrical and optoelectronic properties, and methods of preparation. A number of heterojunction devices are also considered, from photovoltaic converters to photodiodes, transistors, and injection lasers. Comprised of eight chapters, this volume begins with an overview of the theory of heterojunctions and a discussion on abrupt isotype and anisotype heterojunctions, along with graded heterojunctions. The reader is then introduced to the energy band profiles of isotype and anisotype heterojunctions, the practical aspects of their fabrication and characterization, and their electronic and optoelectronic properties. Some methods used in the preparation of heterojunctions are also described, including the chemical method, solution growth method, alloying method, and sputtering method. The remaining chapters focus on the characterization of the grown layers, examples of heterojunction devices, and experimental work on heterojunctions. This monograph is intended for research workers and graduate students.
This highly topical study of tropical deforestation in Mexico reports on the first phase of the Land-Cover and Land-Use Change in the Southern Yucatan Peninsular Region Project (LCLUC-SYPR): a large, multi-institutional, and team-based study designed to understand and project land changes in a development frontier that pits the rapidly growing needs of smallholder farmers to cut down forests for cultivation against federally sponsored initiatives committed to various internationalprogrammes of forest preservation and complementary economic programmes.The SYPR project is a response to inderdisciplinary defined research themes deemed critical to global environmental change and complementary international research agendas (e.g. environment and development, ecosystem assessment, biotic diversity). Pivotal among these agendas are those posed by the Land-Use/Cover Change (LUCC) effort of the International Geosphere-Biosphere Programme and the International Human Dimensions of Global Environmental Change Programme as it is linked through such USsponsors as the National Aeronautics and Space Administration (NASA) and the National Science Foundation (NSF). The themes (i.e. questions and subjects) posed by these programmes and organization are 'integrated' or 'synthesis' in kind, meaning that they rest within the intersection of formaldisciplines and are intended to fit into a larger, systems framework about human-environment relationships and the structure and function of the biosphere.The editors of this volume, as most of its contributors, come from the disciplines of geography, ecology, and economics. The lead editor, the geographer B. L. Turner II, has spent most of his career in pursuit of understanding different aspects of tropical deforestation and agriculture.
The genus Verticillium Nees represents one of the world's major fungal pathogens, affecting crop plants mostly in the cool and warm temperate regions, it also occurs in sub-tropical and tropical areas. There are some six species which cause severe wilting in trees, herbaceous plants and plantation crops. Other species are responsible for non-wilt diseases of banana and mushroom, another species infects insects.The monograph provides a comprehensive reference source on Verticillium, enabling research workers to see what has already been achieved and to identify the many new areas of research in which original contributions could be made to further the understanding and control of this important pathogen and the disease it causes.
Ideology dominates social research, encouraged by rejections of nature and the past, and often ignores the direct experience of actual people. This archaeological study takes a different approach, grounding concepts of culture, landscape and art in ecological relations that embrace all of life. An ecological approach considers that life exists in the interactions of people with the environment surrounding them. This theoretical grounding therefore supports research at a local scale and validates the analysis of individual effort. The case studies explore individual perception, action and expression in a startlingly diverse set of objects and features from the past: natural and constructed monuments, ancient and recent rock paintings, petroglyphs, fresco paintings and impressionist landscape art. While traditional cultural approaches render ordinary people as proxies, these individuals, as members of families and communities, do the actual work of society, using their senses, bodies and minds. The analysis here therefore turns away from traditional speculations about the meanings of cultural things to look for evidence of the personal choices of travelers, inhabitants, pilgrims and artists as they acted, and attempt to gain insights from these decisions about the past as lived. The book will be of interest to scholars, researchers and advanced students in culture and society who may be restless in theatres of discourse dominated by self-affirming narratives, who wish to consider the fields of possibility in an environmental perspective that integrates culture with nature and humans with other beings in a singular, physical world.
This book presents the basic theory and application of the Monte Carlo method to the electronic structure of atoms and molecules. It assumes no previous knowledge of the subject, only a knowledge of molecular quantum mechanics at the first-year graduate level. A working knowledge of traditional ab initio quantum chemistry is helpful, but not essential.Some distinguishing features of this book are:
