The contemporary crisis of emerging disease has been a century and a half in the making. Human, veterinary, and crop health practitioners convinced themselves that disease could be controlled by medicating the sick, vaccinating those at risk, and eradicating the parts of the biosphere responsible for disease transmission. Evolutionary biologists assured themselves that coevolution between pathogens and hosts provided a firewall against disease emergence in new hosts. Most climate scientists made no connection between climate changes and disease. None of these traditional perspectives anticipated the onslaught of emerging infectious diseases confronting humanity today. As this book reveals, a new understanding of the evolution of pathogen-host systems, called the Stockholm Paradigm, explains what is happening. The planet is a minefield of pathogens with preexisting capacities to infect susceptible but unexposed hosts, needing only the opportunity for contact. Climate change has always been the major catalyst for such new opportunities, because it disrupts local ecosystem structure and allows pathogens and hosts to move. Once pathogens expand to new hosts, novel variants may emerge, each with new infection capacities. Mathematical models and real-world examples uniformly support these ideas. Emerging disease is thus one of the greatest climate change–related threats confronting humanity. Even without deadly global catastrophes on the scale of the 1918 Spanish Influenza pandemic, emerging diseases cost humanity more than a trillion dollars per year in treatment and lost productivity. But while time is short, the danger is great, and we are largely unprepared, the Stockholm Paradigm offers hope for managing the crisis. By using the DAMA (document, assess, monitor, act) protocol, we can “anticipate to mitigate” emerging disease, buying time and saving money while we search for more effective ways to cope with this challenge.

This monumental work by the world's preeminent authority on Arctic floras--the first comprehensive, up-to-date botanic manual for this region--is the product of the author's more than forty years of study of circumpolar floras. The book describes and illustrates all flowering plants and vascular cryptograms known to occur in Alaska, the Yukon, the Mackenzie District, and the eastern extremity of Siberia. Some 1,974 taxa, belonging to 1,559 species, occur in this region; all are described. For 1,735 of these, the book provides detailed description, nomenclature, plant drawing, and range maps. In each case, one map gives distribution in the Alaskan region; a second, on circumpolar projection, gives worldwide range. This volume is the first major flora to assemble such comprehensive range data and to provide such maps. An analytic key to all species described is provided for each genus, and there is an artificial key to families. An Introduction describes the past and present climatic, geologic, and ecologic character of the regions covered, the history of botanical collection in these regions, and the book's treatment of botanical and taxonomic details; and lists the plants of neighboring regions likely to occur. Glossary, plant authors' list, bibliography, and indexes are provided. The superb drawings were prepared by Dagny Tande-Lid, and eight pages of illustration in color are included.
A vivid and entertaining account of one man’s extraordinary life, guided by a love of steam trains and an unerring vision to be an engine driver in the days when steam ruled the rails. See through the eyes of a small boy the first stirrings of this enduring passion as, in rapt fascination, he watches trains on the Hull & Barnsley main line in the 1940s, and witness the bucolic beauty of rural life, allied with the poverty and shear hard graft of farm work during the war years, when it seems his dream will be crushed by the daily grind and drudgery. Share the author’s exuberance as, having hazarded all, he succeeds in joining the London & North Eastern Railway as a lad porter, before being introduced to the hallowed world of the Locomotive Department, progressing through the ranks to finally fulfil his dream. On this journey share his exhilaration as he thunders down the main line on a locomotive pushed to its limits, spewing fire and brimstone; and witness a host of steam train escapades, adventures, and mishaps, from the farcical to tragic. Finally, travel with him to exotic Tanganyika/Tanzania in the 1960s where, during 12 years with East African Railways, he experiences the challenges of epic journeys through the heart of the sun-baked bush, breakdowns, derailments, flooded tracks, and violent mutiny, as well as the joy of driving the mighty and exemplary 30 Class, ending with the pinnacle of his career: that of becoming Locomotive Inspector.
Although beloved by performers and audiences alike, music scholars have generally viewed J.S. Bach's Ich hatte viel Bekümmernis in meinem Herzen (Cantata 21) as one of the composer's weaker compositions. In Tears into Wine, renowned Bach scholar Eric Chafe challenges the scholarly consensus, arguing that Cantata 21 is an exceptionally carefully designed work, and that it displays a convergence of musical structure and theological purpose that is paradigmatic of Bach's sacred work as a whole.

The most insightful and intuitive guide to clean and simple software. I recommend this to all software developers." - Rob Pacheco, Vision Government Solutions Grokking Simplicity is a friendly, practical guide that will change the way you approach software design and development. Distributed across servers, difficult to test, and resistant to modification—modern software is complex. Grokking Simplicity is a friendly, practical guide that will change the way you approach software design and development. It introduces a unique approach to functional programming that explains why certain features of software are prone to complexity, and teaches you the functional techniques you can use to simplify these systems so that they’re easier to test and debug. Purchase of the print book includes a free eBook in PDF, Kindle, and ePub formats from Manning Publications. About the technology Developers rightly fear the unintended complexity that infects most code. This book shows you how to write software that keeps complexity close to its inherent minimum. As you write software you should distinguish between code that alters your system’s state, and code that does not. Once you learn to make that distinction, you can refactor much of your state-altering “actions” into stateless “calculations.” Your software will be simpler. About the book The book also teaches you to solve the complex timing bugs that inevitably creep into asynchronous and multithreaded code. In advanced sections of the book you learn how composable abstractions help avoid repeating code and open up new levels of expressivity. What's inside Patterns for simpler code Powerful time modeling approaches to simplify asynchronous code How higher-order functions can make code reusable and composable About the reader For intermediate and advanced developers building complex software. Exercises, illustrations, self-assessments, and hands-on examples lock in each new idea. About the author Eric Normand is an expert software developer who has been an influential teacher of functional programming since 2007.

This book deals with the Old Testament theme of the vengeance of YHWH, discussing both the exegetical and theological aspects of a biblical notion that until now has received far too little attention in scholarly research. After an exploration of the Umwelt use of the root NQM (vengeance/avenge), in the main part of the study all relevant Old Testament texts are dealt with in a thorough exegetical investigation. This leads to a theological outline which stresses the important place and positive function of God's vengeance in the Old Testament revelation. The theories of G.E. Mendenhall, P. Volz and K. Koch with regard to the theme of vengeance are criticized. Of special interest are the additional sections on the issues of blood vengeance and the imprecatory prayers.
