From the President of the Research Society on Alcoholism On behalf of the Research Society on Alcoholism, I am pleased to introduce this thirteenth volume of Recent Developments in Alcoholism about alcohol and violence. Current concepts are presented in well-organized sections that - cus on epidemiology, neurobiology, psychology, and family issues. It is - coming increasingly clear that age, gender, socioeconomic circumstances, and genetics affect aggressive behavior and vulnerability to alcoholism. This v- ume contains up-to-date discussions of these issues. Indeed, the information presented...

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...

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...

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...

Fuzzy sets were introduced by Zadeh (1965) as a means of representing and manipulating data that was not precise, but rather fuzzy. Fuzzy logic pro vides an inference morphology that enables approximate human reasoning capabilities to be applied to knowledge-based systems. The theory of fuzzy logic provides a mathematical strength to capture the uncertainties associ ated with human cognitive processes, such as thinking and reasoning. The conventional approaches to knowledge representation lack the means for rep resentating the meaning of fuzzy concepts. As a consequence, the approaches based...

This is the second volume on probiotics published by Chapman & Hall. Building on the first volume which covered the scientific basis, this important new volume covers practical aspects and the beneficial and therapeutic effects of positive manipulation of an individual's gut flora. The editor, Roy Fuller has drawn together an impressive international list of contributors, each with direct experience of the positive applications of probiotics. Probiotics 2 provides vital new information for microbiologists, nutritionists and dieticians, food scientists, gastroenterologists and physicians.
