In the Introduction to the Polish-language version of the present book I expressed the hope that Polish studies in semiotics would before long be numerous enough to make possible another anthology on semiotics in Poland containing material published since 1970. That hope has in fact come true. The fact that semiotic research has been gaining momentum in this country is reflected in the growing interest in the discipline, in expanding international contacts, and in the steady increase in the number of publications. Thus, 1972 saw the setting up of the Department of Logical Semiotics, headed by the present writer, at Warsaw University Institute of Phi losophy. The seminar on semiotics, which I started in 1961, had met more than two hundred times by the end of 1976; since 1968, meetings have been held jointly with the Polish Semiotic Society. Another semi nar, confined to university staff and concerned with logical semiotics, which was inithted in 1970, had met more than fifty times by the end of 1976. The former seminar often plays host to foreign visiting pro fessors; so far scholars from Australia, Belgium, Britain, Canada, Czechoslovakia, France, the German Democratic Republic, Italy, the Netherlands, the Soviet Union, and the United States have attended."

Im Rahmen dieser mehrbandigen, nach Kulturarten geordneten Buchreihe wird eine Anleitung zum rechtzeitigen und sicheren Erkennen der Erreger von Krankheiten und der Ursachen von Beschadigungen der landwirtschaftlichen und gartnerischen Kulturpflanzen gegeben. Einer ausfuhrlichen Bestimmungstabelle folgt eine textliche Darstellung der jeweiligen Schadursache sowie eine Darstellung der fur die Diagnose wichtigen Merkmale auf Aquarelltafeln und schematischen Zeichnungen. Innerhalb jeder Kulturart sind die Schadursachen und -erreger geordnet nach: - abiotischen Schaden/Ernahrungsstoerungen - Virosen und Mycoplasmosen - Bakterien - Mykosen - tierischen Schaderregern. Berucksichtigt werden in erster Linie mitteleuropaische Arten.

All treaties, from human rights to international trade, include formal exceptions that allow governments to legally break the rules that they have committed to, in order to deal with unexpected events. Such institutional 'flexibility' is necessary, yet it raises a tricky theoretical question: how to allow for this necessary flexibility, while preventing its abuse? Krzysztof J. Pelc examines how designers of rules in vastly different settings come upon similar solutions to render treaties resistant to unexpected events. Essential for undergraduate students, graduate students, and scholars in political science, economics, and law, the book provides a comprehensive account of the politics of treaty flexibility. Drawing on a wide range of evidence, its multi-disciplinary approach addresses the paradoxes inherent in making and bending international rules.
