From February 24 -28, 1992 an international symposium on Durability of Disease Resistance was held at the International Agricultural Centre in Wageningen, the Netherlands. The symposium, organized by the Department of Plant Breeding of Wageningen Agricultural University and the Centre for Plant Breeding and Repro duction Research, CPRO-DLO, was part of the DGIS funded programme Durable Resistance in Developing Countries. Without any form of prevention or protection nearly all crops will be seriously or even severely damaged by a range of pathogens. In modern agriculture man has been able to control many if not most pathogens using i) pesticides, ii) phyto sanitary methods such as control of seed and plant material in order to start a crop disease free, iii) agronomic measures such as crop rotation, iv) disease resis tance or combinations of these measures. Over the years the use of pesticides has increased enormously and so did the pro blems associated with pesticide use, such as environmental pollution and building of resistance and tolerance to these pesticides in the pathogens. The use of resis tance too increased strongly over the years and here too problems arose.

The application of evolutionary biology addresses a wide range of practical problems in medicine, agriculture, the environment, and society. Such cutting-edge applications are emerging due to recent advances in DNA sequencing, new gene editing tools, and computational methods. This book is about applied evolution – the application of the principles of and information about evolutionary biology to diverse practical matters. Although applied evolution has existed, unrecognized, for a very long time, today’s version has a much wider scope. Evolutionary medicine has formed into its own discipline. Evolutionary approaches have long been employed in agriculture and in conservation biology. But Darwin’s reach now extends beyond just these three fields. It now also includes forensic biology and the law. Ideas from evolutionary biology can be used to inform policy regarding foreign affairs and national security. Applied evolution is not only interdisciplinary, but also multidisciplinary. Consequently, this book is for experts in one field who are interested in expanding their evolutionary horizons. It is also for students, at the undergraduate and graduate levels. One of the public relations challenges faced by evolutionary biology is that most people do not see it being all that relevant to their daily lives. Even many who accept evolution do not grasp how far Darwin’s reach extends. This book will change that perception. Key Features Emphasizes the expanding role evolutionary biology has in today’s world. Includes examples from medicine, law, agriculture, conservation, and even national security Summarizes new technologies and computational methods that originated as innovations based in part or whole on evolutionary theory. Current. Has extensive coverage of the COVID-19 pandemic and other recent topics. Documents the important role evolution plays in everyday life. Illustrates the broadly interdisciplinary nature of evolutionary theory. Resources The applications of evolutionary biology are far too numerous to include in just one book. Plus, new scientific findings emerge almost every day underscoring the central role evolution plays in our lives. The author has established a blog site to highlight these fascinating discoveries.

RESISTANCE AND THE PROCESS OF THERAPEUTIC CHANGE Paul L. Wachtel Psychotherapy, whether practiced from a psychodynamic or a behavioral point of view,! is rarely as straightforward as textbooks and case reports usually seem to imply. More often the work proceeds in fits and starts (and often does not seem to be proceeding at all, but rather unraveling or moving backward). The "typical" case is in fact quite atypical. Almost all cases present substantial difficulties for which the therapist feels, at least some of the time, quite unprepared. Practicing psychotherapy is a difficult-if also rewarding-way to earn a living. It is no profession for the individual who likes certainty, predictability, or a fairly constant sense that one knows what one is doing. There are few professions in which feeling stupid or stymied is as likely to be a part of one's ordinary professional day, even for those at the pinnacle of the field. Indeed, I would be loath to refer a patient to any therapist who declared that he almost always felt effective and clear about what was going on. Such a feeling can be maintained, I believe, only by an inordinate amount of bravado and lack of critical self-reflection. But the therapist trying to get some ideas about how to work with 1 These are, of course, not the only two points of view in psychotherapy; nor do I believe they are the only two of value.

This book describes antibiotic resistance amongst pathogenic bacteria. It starts with an overview of the erosion of the efficacy of antibiotics by resistance and the decrease in the rate of replacement of redundant compounds. The origins of antibiotic resistance are then described. It is proposed that there is a large bacterial resistome which is a collection of all resistance genes and their precursors in both pathogenic and non-pathogenic bacteria. Ongoing resistance surveillance programs are also discussed, together with the perspective of a clinical microbiologist. The book then turns to specific themes such as the most serious area of resistance in pathogens, namely in Gram-negative organisms. The role of combinations of antibiotics in combating resistance emergence is discussed, particularly in the tuberculosis field, and then the importance of non-multiplying and persistent bacteria which are phenotypically resistant to antibiotics and prolong the duration of therapy of antibiotics which leads to poor compliance and resistance emergence. The role of anti-microbial compounds in textiles is covered, with its potential to exacerbate the spread of resistance. Then, efflux pumps are discussed. The final chapter describes the compounds which are in late stage clinical development, illustrating the paucity of the antibiotic pipeline, especially for Gram-negative bacteria.

This book, first published in 1923 as the third edition of a 1905 original, provides an account of the principles of experimental electricity.

The French resistance to Nazi occupation during World War II was a struggle in which ordinary people fought for their liberty, despite terrible odds and horrifying repression. Hundreds of thousands of Frenchmen and women carried out an armed struggle against the Nazis, producing underground anti-fascist publications and supplying the Allies with vital intelligence. Based on hundreds of French eye-witness accounts and including recently-released archival material, The Resistanceuses dramatic personal stories to take the reader on one of the great adventures of the 20thcentury. The tale begins with the catastrophic Fall of France in 1940, and shatters the myth of a unified Resistance created by General de Gaulle. In fact, De Gaulle never understood the Resistance, and sought to use, dominate and channel it to his own ends. Brave men and women set up organisations, only to be betrayed or hunted down by the Nazis, and to die in front of the firing squad or in the concentration camps. Over time, the true story of the Resistance got blurred and distorted, its heroes and conflicts were forgotten as the movement became a myth. By turns exciting, tragic and insightful, The Resistancereveals how one of the most powerful modern myths came to be forged and provides a gripping account of one of the most striking events in the 20thcentury.
