Humans are highly mobile but at a price: over a million people are killed annually on the road, at least 30 times as many are injured, of whom one in ten may be permanently disabled. How can we design a road or highway or transport system so as to provide both a high level of mobility and a high level of safety? For too long, from the perspective of the road user, highway engineers have had to employ their intuitions, personal experiences, shared "know-how" and a "suck-it-and-see" approach in many elements of highway design. Now the science of human behaviour can provide both fundamental knowledge and principles to enable matching roadway and transport system design to human strengths, limitations and variability in performance; an understanding of human contributory factors in accidents; and the undertaking of informed safety audits and reviews. This book aims to help you ask the right questions about the issues raised.

There is a marked and most unfortunate dichotomy in the studies of avian eggs and hence in the application of new findings in commerce. Thus over the past twenty years there has been a renewed interest in the contribu tions of various parts of an egg to embryo development. This is best illustrated by those studies that have explored the diffusion of respiratory gases across the shell and at long last have provided a fundamental definition of a previously nebulous term, porosity. The activity in this general area has led in the past four years to the publication of three major books dealing with many aspects of egg structure, function and embryogenesis. When brows­ ing over these books, two developments are evident. First, the advantages that are to be gained by comparative studies. Thus it is now common to see within a single book articles concerned with the eggs of a range of avian species as well as those of reptiles. Second, it is evident that zoologists and physiologists as well as those employed in large breeding firms are all contributing to an improvement of our knowledge of the egg's role in the breeding biology of birds. Comparative studies are a very uncommon feature of studies concerned with bacterial infection of eggs.

This second volume on probiotics builds on the first volume which explained the scientific basis, covering practical aspects and the beneficial and therapeutic effects of positive manipulation of an individual's gut flora. It provides recent information for microbiologists, nutritionists and dieticians, food scientists, gastroenterologists and physicians.

The two previous books "Probiotics, The Scientific Basics" and "Probiotics 2, Applications and Practical Aspects" covered the general area of probiotics and their uses. The present volume focuses on the important and rapidly expanding subject of immunomodulation by intestinal micro-organisms and brings together the results and opinions of leading researchers from all over the world. They bring to the compilation a depth of knowledge and analysis, which assures the book of serious consideration by all workers in probiotics and related disciplines.

In this exciting new volume, six of the world''s leading scholars write about the contribution made to our understanding of human behaviour and the human mind by seven great figures of the last 100 years: Lorenz and Tinbergen, Skinner, Piaget, Freud, James and Galton. Their seminal work on ethology, behaviourism, child development, psychoanalysis, perception and heredity provide the basis for much of today''s psychological thinking and research. An account of the thought of each key figure is given together with a brief biography. Each contribution is written so that is can be understood by anyone interested in ideas of these major figures. Based on a series of lectures given at Trinity College, Dublin, Seven Pioneers of Psychology provides a clear, accessible and extremely readable account of seven of the great pioneers in exploring the human condition.

The way in which probiotics work is still not clearly defined, but it is becoming more and more apparent that immune stimulation is an important feature in some of the observed effects. In the previous two books in this series the scientific basis and the practical applications were considered. It seemed that the immunogenic potential of probiotics merited a book of its own with experts from all over the world covering the general effect of the gut microflora on immunity as well as the particular response that pro biotic microorganisms generate. The importance of immune stimulation by probiotic organisms cannot be overemphasised. It opens up the technique for use, not only as a treatment for intestinal diseases, but also as a treatment that could be effective against infections outside the gastrointestinal tract. This book considers how the body reacts to the presence of orally administered microorganisms (normally lactic acid bacteria). The responses may be in the form of antibodies (lgA, IgG, IgM), cytokines, killer cells or macrophage activity. Do these responses result in antagonism of the stimulating bacteria, do they affect the composition of the indigenous gut microflora and are they sufficienty strong to kill bacterial pathogens or tumour cells? Where we have answers these will be reported and discussed; where there are no answers there will be speculation and prediction.

R. Fuller 1.1 DEVELOPMENT OF COMMERCIAL PREPARATIONS The history of the probiotic effect has been well documented many times previously (see e.g. Bibel, 1982; Fuller, 1992). The consumption of fermented milks dates from pre-biblical times but the probiotic concept was born at the end of the last century with the work of Metchnikoff at the Pasteur Institute in Paris. In the century that has elapsed since Metchnikoff's work, the probiotic concept has been accepted by scientists and consumers throughout the world. Attempts to refine the practice from the use of traditional soured milks to preparations containing specific micro­ organisms have occupied the thoughts and endeavours of scientists in many different countries. But, in spite of the large amount of effort expended in attempting to explain and define the effect, it has to be admitted that little is known of the way in which probiotics operate. There are likely to be several different mechanisms because it seems highly improbable that a mode of action that explains resistance to microbial infection will also hold true for improved milk production or alleviation of lactose malabsorption.
