Encyclopedia of Communication Theory


Book Description

The Encyclopedia of Communication Theory provides students and researchers with a comprehensive two-volume overview of contemporary communication theory. Reference librarians report that students frequently approach them seeking a source that will provide them with a quick overview of a particular theory or theorist - just enough to help them grasp the general concept or theory and its relation to the discipline as a whole. Communication scholars and teachers also occasionally need a quick reference for theories. Edited by the co-authors of the best-selling textbook on communication theory and drawing on the expertise of an advisory board of 10 international scholars and nearly 200 contributors from 10 countries, this work finally provides such a resource. More than 300 entries address topics related not only to paradigms, traditions, and schools, but also metatheory, methodology, inquiry, and applications and contexts. Entries cover several orientations, including psycho-cognitive; social-interactional; cybernetic and systems; cultural; critical; feminist; philosophical; rhetorical; semiotic, linguistic, and discursive; and non-Western. Concepts relate to interpersonal communication, groups and organizations, and media and mass communication. In sum, this encyclopedia offers the student of communication a sense of the history, development, and current status of the discipline, with an emphasis on the theories that comprise it.




Light as an Energy Source and Information Carrier in Plant Physiology


Book Description

A NATO Advanced Study Institute on "Light as Energy Source and Information Carrier in Plant Photo physiology" was held at Volterra, Italy, from September 26 to October 6, 1994, in order to consider the fundamental role that light plays in plant growth and development. This book summarises the main lectures given at this meeting which concentrated on both photochemical energy conversion and signalling (photosensing) aspects. Light harvesting and conversion into chemical energy in photosynthesis occurs at the level of chlorophyll/carotenoid containing photosystems in plants. Pigments are non covalently bound to a variety of polypeptides which serve as a specific scaffolding, necessary to determine the energy coupling between pigments and thus allowing rapid excitation energy trasfer from the antenna to the special reaction centre chlorophylls. Data from transient, time resolved spectroscopies, in the femtosecond and picosecond domain, together with model calculations, suggest that this process occurs in the 20-100 picosecond time span. The special ~ll u~ture of reaction centre complexes, ensures rapid primary charge separation, probably in the order of 1-3 picoseconds, with subsequent charge stabilisation reactions proceeding in the hundreds of picoseconds range. The recently resolved crystallographic structure of LHCII, the principal antenna complex of plants, allows precise determination of pigment-pigment distances and thus permits calculation of approximate chlorophyll-chlorophyll Forster hopping rates, which are in good agreement with time resolved measurements.




Creative Conservation


Book Description

Past progress and future challenges R.J. Wheater Royal Zoological Society of Scotland, Edinburgh, UK. In the past two decades much has been achieved in the sphere of breeding endangered species, and we should be pleased that our co operative efforts have already borne so much fruit. However, on balance and despite the best efforts of conservationists, the position of wildlife in the wild places where they are best conserved has become worse, often dramatically worse. Before returning to the United Kingdom in 1972, I was in Uganda for 16 years, most of which time was spent as Chief Warden of Murchison Falls National Park. Our main problem was that an over-population of large mammals was having a devastating impact on the habitat. Devas tation was being wrought on woodland areas by the arrival of large numbers of elephants into the sanctuary of the Park, following changes in land use in the areas outside the Park. These changes were in response to the requirements of an ever-expanding human population.




Biotremology: Studying Vibrational Behavior


Book Description

This volume is a self-contained companion piece to Studying Vibrational Communication, published in 2014 within the same series. The field has expanded considerably since then, and has even acquired a name of its own: biotremology. In this context, the book reports on new concepts in this fascinating discipline, and features chapters on state-of-the art methods for studying behavior tied to substrate-borne vibrations, as well as an entire section on applied biotremology. Also included are a historical contribution by pioneers in the field and several chapters reviewing the advances that have been made regarding specific animal taxa. Other new topics covered are vibrational communication in vertebrates, multimodal communication, and biotremology in the classroom, as well as in art and music. Given its scope, the book will appeal to all those interested in communication and vibrational behavior, but also to those seeking to learn about an ancient mode of communication.

Bones, Bodies Amd Behavior


Book Description

History of Anthropology is a series of annual volumes, inaugurated in 1983, each broadly unified around a theme of major importance to both the history and the present practice of anthropological inquiry. Bones, Bodies, Behavior, the fifth in the series, treats a number of issues relating to the history of biological or physical anthropology: the application of the "race" idea to humankind, the comparison of animals minds to those of humans, the evolution of humans from primate forms, and the relation of science to racial ideology. Following an introductory overview of biological anthropology in Western tradition, the seven essays focus on a series of particular historical episodes from 1830 to 1980: the emergence of the race idea in restoration France, the comparative psychological thought of the American ethnologist Lewis Henry Morgan, the archeological background of the forgery of the remains "discovered" at Piltdown in 1912, their impact on paleoanthropology in the interwar period, the background and development of physical anthropology in Nazi Germany, and the attempts of Franx Boas and others to organize a consensus against racialism among British and American scientists in the late 1930s. The volume concludes with a provocative essay on physical anthropology and primate studies in the United States in the years since such a consensus was established by the UNESCO "Statements on Race" of 1950 and 1951. Bringing together the contributions of a physical anthropologist (Frank Spencer), a historical sociologist (Michael Hammond), and a number of historians of science (Elazar Barkan, Claude Blanckaert, Donna Haraway, Robert Proctor, and Marc Swetlitz), this volume will appeal to a wide range of students, scholars, and general readers interested in the place of biological assumptions in the modern anthropological tradition, in the biological bases of human behavior, in racial ideologies, and in the development of the modern human sciences.




Northern Territory Dictionary of Biography


Book Description

This revised edition of the Northern Territory Dictionary of Biography brings together the entries from the original three volumes, published in 1990, 1992 and 1996. The Dictionary spans the period from the early British and French explorers of the Northern Territory coast to the mid 1990s and aims to provide a broad reflection of life in the Territory rather than focusing on eminent public figures. In some cases this has meant that some subjects are included about whom relatively little is known. Authors come from the widest possible cross-section of the community and there is a considerable range of writing styles. The principal interest of the volume is the Northern Territory. In all cases, the Territory experience of subjects, however eminent they might have been elsewhere, is thus the focal point of entries.This volume is available on CD (ISBN 9780980384697) and in this limited paperback edition.
