"Sidney Coleman was the master teacher of quantum field theory. All of us who knew him became his students and disciples. Sidney’s legendary course remains fresh and bracing, because he chose his topics with a sure feel for the essential, and treated them with elegant economy."Frank WilczekNobel Laureate in Physics 2004Sidney Coleman was a physicist's physicist. He is largely unknown outside of the theoretical physics community, and known only by reputation to the younger generation. He was an unusually effective teacher, famed for his wit, his insight and his encyclopedic knowledge of the field to which he made many important contributions. There are many first-rate quantum field theory books (the venerable Bjorken and Drell, the more modern Itzykson and Zuber, the now-standard Peskin and Schroeder, and the recent Zee), but the immediacy of Prof. Coleman's approach and his ability to present an argument simply without sacrificing rigor makes his book easy to read and ideal for the student. Part of the motivation in producing this book is to pass on the work of this outstanding physicist to later generations, a record of his teaching that he was too busy to leave himself.

The efficient use of natural resources is key to a sustainable economy, and yet the complexities of the physical aspects of resource efficiency are poorly understood. In this challenging book, the author proposes a major advance in our understanding of this topic by analysing resource efficiency and efficiency gains from the perspective of common pool resources, applying this idea particularly to water resources and its use in irrigated agriculture. The author proposes a novel concept of "the paracommons", through which the savings of increased resource efficiency can be viewed. In effect he asks; "who gets the gain of an efficiency gain?" By reusing, economising and avoiding losses, wastes and wastages, freed up resources are available for further use by four ‘destinations’; the same user, parties directly connected to that user, the wider economy or returned to the common pool. The paracommons is thus a commons of – and competition for – resources salvaged by changes to the efficiency of natural resource systems. The idea can be applied to a range of resources such as water, energy, forests and high-seas fisheries. Five issues are explored: the complexity of resource use efficiency; the uncertainty of efficiency interventions and outcomes; destinations of freed up losses, wastes and wastages; implications for resource conservation; and the interconnectedness of users and systems brought about by efficiency changes. The book shows how these ideas put efficiency on a par with other dimensions of resource governance and sustainability such as equity, justice, resilience and access.

Leadership is vital to creativity and successful innovation in groups and organizations; leadership is however seldom studied in the academic literature as a creativity driver. One reason for the lack of attention paid to leadership’s effect on creativity may be the common belief that creativity cannot and should not be managed. Creative individuals and groups are regarded as, and indeed often are, autonomous and self-driving. From this belief the erroneous conclusion is drawn that there is no need for leadership in creative environments and situations. The better conclusion, proposed by this book, is that leadership not only stimulates creativity, but that such a leadership in the science, technology, and innovation fields should specifically possess at least two features: a) expertise in the field(s), and b) an ability to create, support, and encourage individuals, groups, and creative knowledge environments. A number of specialist authors in this volume offer original theoretical, empirical, and applied chapters that elucidate how to better organize and lead creative efforts in science, technology, and innovation. A number of important research questions are raised and answered, including: What kinds of leaderships are needed at different levels of S&T organizations for a creative output? What social and cognitive abilities and skills are needed for leadership in creative environments? How does leadership vary with different phases of the creative process? This book offers concrete analysis of how leaders and managers can facilitate, promote, and organize for creative performance in science, technology, and in innovating organizations, making it required reading for academic and industrial research leaders, scientists, and engineers.

Economic models are used to show the extent of the difficulties involved in monitoring and enforcing pollution control laws on a continual basis. The authors make several recommendations for policy change. They also show that high rates of compliance can be achieved within tight budget constraints.Originally published in 1986
