Despite hundreds of millions of visitors each year, zoos have remained outside of the realm of philosophical analysis. This lack of theoretical examination is interesting considering the paradoxical position within which a zoo is situated, being a space of animal confinement as well as a site that provides valuable tools for species conservation, public education, and entertainment. Why Do We Go to the Zoo? argues that the zoo is a legitimate space of academic inquiry. The modes of communication taking place at the zoo that keep drawing us back time and time again beg for a careful investigation. In this book, the meaning of the zoo as communicative space is explored. This book relies on the phenomenological method from Edmund Husserl and a rhetorical approach to examine the interaction between people and animals in the zoo space. Phenomenology, the philosophy of examining the engaged everyday lived experience, is a natural method to use in the project. Despite its rich history and tradition it is interesting that there are very few books explaining "how to do" phenomenology. Why Do We Go to the Zoo? provides a detailed account of how to actually conduct a phenomenological analysis. The author spent thousands of hours in zoos watching people and animals interact as well as talking with people both formally and informally. This book asks readers to bracket their preconceptions of what goes on in the zoo and, instead, to explore the meaning of powerful zoo experiences while reminding us of the troubled history of zoos.

Animal cell technology is a newly growing discipline of cell biology which aims not only to understand structure, function and behavior of differentiated animal cells but also to uncover their ability useful for industrial and medical purpose. The goal of animal cell technology includes clonal expansion of differentiated cells with useful ability, optimization of their culturing in industrial scale, modulation of their ability for production of pharmaceutical proteins and monoclonal antibodies, and newly application to gene therapy and organ culture. The last seven Annual Meetings of the Japanese Association for Animal Cell Technology (JAACT) had attracted increasing number of participants. At the Eighth Meeting (JAACT'95) held in Iizuka from November 6 through 10, 1995. Before this Meeting, we were all shocked by the sudden death of a founder of JAACT, the late Prof. Hiroki Murakami in February of this year. But we had more than 90 participants from outside of Japan and 170 from Japan in this Meeting. The editors express their sincere gratitude to all researchers who joined the meeting, to the organizers of the Symposium Sessions, to members of the organizing committee who dedicated themselves in assuring the Meeting's success in the absence of Prof. H. Murakami, and the graduates and undergraduates students of Kyushu University and Kyushu Institute of Technology who supported management of the Meeting. We also thank the Japanese Bioindustry Association and Fukuoka Science & Technology Foundation for the financial support.

Continuous cell lines derived from human cancers are the mostwidely used resource in laboratory-based cancer research. The first 3 volumes of this series on Human Cell Culture are devoted to these cancer cell lines. The chapters in these first 3 volumes have a common aim. Their purpose is to address 3 questions offundamental importance to the relevanceof human cancer cell lines as model systems of each type of cancer: 1. Do the cell lines available accurately represent the clinical presentation? 2. Do the cell lines accurately represent the histopathology of the original tumors? 3. Do the cell lines accurately represent the molecular genetics of this type of cancer? The cancer cell lines available are derived, in most cases, from the more aggressive and advanced cancers. There are few cell lines derived from low grade organ-confined cancers. This gap can be filled with conditionally immortalized human cancer cell lines. We do not know why the success rate for establishing cell lines is so low for some types of cancer and so high for others. The histopathology of the tumor of origin and the extent to which the derived cell line retains the differentiated features of that tumor are critical. The concept that a single cell line derived from a tumor at a particular site is representative oftumors at that site is naive and misleading."

After volume 33, this book series was replaced by the journal "Evolutionary Biology." Please visit www.springer.com/11692 for further information.

This volume continues bringing to readers the findings of eminent evolutionary biologists and paleobiologists. Among the topics discussed in this book are the origin of the dermal skeleton in conodont chordates, patterns of nucleotide substitution and codon usage in plasmid DNA evolution, a model to explain phenotype stability in functional systems, and inter-island speciation of Hawaiian biota.

Morphometrics is concerned with the study of variations and change in the form (size and shape) of organisms or objects adding a quantitative element to descriptions and thereby facilitating the comparison of different objects and organisms. This volume provides an introduction to morphometrics in a clear and simple way without recourse to complex mathematics and statistics. This introduction is followed by a series of case studies describing the variety of applications of morphometrics from paleontology and evolutionary ecology to archaeological artifacts analysis. This is followed by a presentation of future applications of morphometrics and state of the art software for analyzing and comparing shape.

This book, written by the leading international research scientists in the field, is the first to cover all aspects of research into the welfare of dairy, veal and beef cattle. The book provides a thorough and critical review of the most up-to-date research on the welfare of cattle, covering behaviour, nutrition and feeding, housing and management, stockmanship, and stress physiology, as well as transport and slaughter. It provides a detailed and critical analysis of the main indicators of animal welfare and covers the main threats to animal welfare in modern cattle production systems. Although the focus is largely on cattle in developed countries, this book should also be of relevance in developing countries, where issues affecting the welfare of domestic animals are beginning to be addressed. The book is intended for researchers and research students in veterinary and animal science and animal welfare science, as well as professionals in the beef and dairy industries.

Hepatitis viruses research started more than fifty years ago. The names of hepatitis A and hepatitis B were introduced in 1947 when it became clear that there were two types of hepatitis that were transmitted either enterically or parenterally. It became apparent in the 1970's that there were additional hepatitis viruses distinct from hepatitis A and hepatitis B, and thus, the term non-A, non-B hepatitis was introduced. The non-A, non-B hepatitis was further divided into post-transfusion non-A, non-B hepatitis and enterically-transmitted non-A, non-B hepatitis in the 1980's. By the end of the 1980's, both post-transfusion non-A, non-B virus and enterically-transmitted non-A, non-B virus had been identified and renamed hepatitis C virus and hepatitis E virus, respectively. Hepatitis delta antigen was first recognized as an antigen associated with hepatitis B virus infection in the 1970's. In the early 1980's, a virus was isolated and named hepatitis delta virus. These five different hepatitis viruses have distinct replication pathways and are major health concerns. They have become an important topic for teaching to graduate-level and medical students. Hepatitis Viruses provides a comprehensive, up-to-date review of these viruses to readers. Each chapter is written by one of the top researchers in the field, and topics include: the epidemiology and the natural history of infection of these viruses, the molecular biology and the replication cycle of individual hepatitis viruses, host-virus interactions and the pathogenesis of hepatitis viruses, the immunology of hepatitis viruses, the relationship between hepatitis viruses and hepatocellular carcinoma, the viral vaccines and antiviral drugs. This book can serve as a supplemental reading material to graduate students and medical students, and to any researcher who would like to learn more about hepatitis viruses.

Animal cell technology is a growing discipline of cell biology, which aims not only to understand structures, functions, and behaviours of differentiated animal cells but also to ascertain their ability to be used for industrial and medical purposes. The goal of animal cell technology includes accomplishments of clonal expansion of differentiated cells with useful ability, optimisation of their culture conditions, modulation of their ability for production of medically and pharmaceutically important proteins, and the application of animal cells to gene therapy, artificial organs, and functional foods. This volume gives the reader a complete review of the present state of the art in Japan and other countries where this field is well advanced. The Proceedings will be useful for cell biologists, biochemists, molecular biologists, immunologists, biochemical engineers, and other disciplines related to animal cell culture, working in either academic environments or in industries of biotechnology and pharmacy.

This dictionary contains terms concerning veterinary medicine in general, infectious, parasitic and non-infectious diseases, and anatomy and physiology of domestic animals. These veterinary terms formerly appeared in the "Dictionary of Animal Production Terminology" of the European Assocation for Animal Production, published by Elsevier in 1985. During the preparation of a new edition of this dictionary, it was decided due to the increasing specialization in animal production and of the associated terminology, to divide it into two volumes, one devoted to animal husbandry terms and the other to veterinary terms. Consequently, specialists in animal production and in animal health who have to work in many languages should consult not only the present volume, but also its companion volume which deals with animal production.

The dictionary will be a valuable reference tool for all those engaged in animal health who have to work in four languages.

Waste water treatment is the largest biotechnology industry in the world, handling and disposing of domestic and industrial wastes so they present no threat to the general populace or the environment at large. The activated sludge process is the cornerstone of sewage treatment systems. Although it is a biological process and has been in use for more than 80 years, we still lack detailed understanding of how it works and how its performance might be better controlled and manipulated. This book presents a comprehensive review of what is currently known about the general microbiology of activated sludge and some of the bacteria responsible for the major operational problems encountered. Current understanding and the existing literature are critically assessed and new potentially valuable areas for research suggested. Methodology particularly appropriate to the study of the bacteria that cause bulking and foaming is described, and there is an identification section consisting of photomicrographs and detailed descriptions of the filamentous and other bacteria commonly seen in activated sludge plants. The impact of molecular methods on our understanding of activated sludge microbiology is emphasized throughout the book. The book will be of immediate interest to both microbiologists and waste water engineers, and has been written so as to be relevant and understandable to both. It will also be of interest and value to postgraduate students and researchers working in the fields of environmental engineering, general microbiology and microbial ecology.

Products from Cells - Cells as Products This book ist he "lasting" product, a resource ofup to date information in the scientific literature fort he field ofanimal cell tec hnology, as it was presented during a pleasant and s timulating mee ting that was held in Lugano Switzerland in April 1999. "Products" appeartwice int he title oft he conference. This clearly indicates the fact that the focus oft he papers presented during this meeting was really the application ofn ew technologies (novel reactors or novel vectors, for example for the preparation and/ort he more efficient generation ofproducts ) that could be used, mainly, int he medical field. Classical approaches forthe use ofa nimal cells, for example forthe p r oduction of virus vaccines for human and animal health, still remain an important technology and still have, surprisingly, quite significant potential for further development and improvement. How ever, it appears that major technological advances an d major growth from an economical point ofview are occurring in other areas. Most importantly, protein production on the basis of recombinant DNA molecules transferred into a nimal cells, appears to be an ever increasing field of interest and innovation, even though the first production scheme with this technology was approved more than 15 years ago.

Epithelia are one of the commonest tissue types in the animal kingdom. Chapters from leading scientists in the major international research laboratories use examples from different systems to illustrate the form and function of epithelia. An important theme is the way in which epithelial cells differentiate to specialized tissue - reversal of this process occurs when cells become tumorigenic.

Contributors to this volume offer new research on extinction processes in birds, nest predation, and song systems, and describes a graphical model that helps predict the reproductive consequences of time allocation between the competing demands of guarding young birds and foraging for food. Current Ornithology is the only English-language publication currently devoted exclusively to extensive reviews and synthesis of topics pertaining to all aspects of the biology of birds. Chapters fall under such diverse rubrics as ecology, evolution, behavior, phylogeny, behavioral ecology, anatomy and physiology, and conservation biology. All authors are leading authorities on their subjects, and each chapter is refereed by experts in the topics covered. Although all chapters focus primarily on birds, some topics, such as the social cognition of birds as compared to primates (Volume 13), have significant application to disciplines outside of ornithology. Current Ornithology aims to provide an accessible, up-to-date, accurate source of data and to contribute to conceptual generalization and unification across the biological sciences.
