Working amidst the global economic turmoil of World War I and the blockade of his neutral homeland, Swedish economist and historian ELI FILIP HECKSCHER (1879-1952) produced this provocative and widely influential analysis of European commercial conflict from the late 17th century through the early 19th century: . What was the impact of the British blockade of France in the 1790s? . How did the national debt and credit system of Britain affect its monetary warfare? . What part did the British colonies in America and later the new United States play in the European economic conflict? . What was done with confiscated goods? . How did smuggling and corruption in the early 1800s change the balance of power? This interpretation of the centuries-long economic clash between Britain, France, and their allies, first published 1922, remains an intriguing work of history today.

In 1860, Oliver Wendell Holmes pointedly expressed himself to the Massachusetts Medical Society: “I firmly believe that if the whole Material Medica, as now used, could be sunk to the bottom of the sea, it would be all the better for mankind, and all the worst for the fishes.” Should one think the same about the current approach in drug discovery from plants? Probably yes. Despite the spending of billions of US dollars, and three decades of efforts, high-throughput screenings have only allowed the discovery of a couple of drugs. One could have reasonably expected the discovery of an arsenal of drugs from the millions of plant extracts randomly tested, but “hits” can be inactive in vitro or too toxic, some molecules need to be metabolized first to be active, and false-positive and false-negative results are common. The bitter truth is that the robotic approach in discovering drugs from plants has proven, to date, its inability to excavate the hundreds of molecules that will contribute to the health progress of Man. However, one can reasonably see that the last patches of primary rainforest on earth hold still hundreds of spectacularly active drugs that await discovery.

There are many good books in the market dealing with the subject of allelopathy. When we designed the outline of this new book, we thought that it should include as many different points of view as possible, although in an integrated general scheme. Allelopathy can be viewed from different of perspectives, ranging from the molecular to the ecosystem level, and including molecular biology, plant biochemistry, plant physiology, plant ecophysiology and ecology, with information coming also from the organic chemistry, soil sciences, microbiology and many other scientific disciplines. This book was designed to include a complete perspective of allelopathic process. The book is divided into seven major sections. The first chapter explores the international development of allelopathy as a science and next section deals with methodological aspects and it explores potential limitations of actual research. Third section is devoted to physiological aspects of allelopathy. Different specialists wrote about photosynthesis, cell cycle, detoxification processes, abiotic and biotic stress, plant secondary metabolites and respiration related to allelopathy. Chapters 13 through 16 are collectively devoted to various aspects of plant ecophysiology on a variety of levels: microorganisms, soil system and weed germination. Fundamental ecology approaches using both experimental observations and theoretical analysis of allelopathy are described in chapters 16 and 17. Those chapters deal with the possible evolutionary forces that have shaped particular strategies. In the section named “allelopathy in different environments”, authors primarily center on marine, aquatic, forest and agro ecosystems. Last section includes chapters addressing application of the knowledge of allelopathy.

This book investigates the meanings and iconography of the Stampede: an invented tradition that takes over the city of Calgary for ten days every July. Since 1912, archetypal "Cowboys and Indians" are seen again at the chuckwagon races, on the midway, and throughout Calgary. Each essay in this collection examines a facet of the experience – from the images on advertising posters to the ritual of the annual parade. This study of the Calgary Stampede as a social phenomenon reveals the history and sociology of the city of Calgary and a component of the social construction of identity for western Canada as a whole.
