The meaning of the business process diagram is the same, regardless of the tool used to create it. But creating models that are correct, complete, and clear demands more than a dictionary of BPMN shapes and symbols. It also requires a methodology for translating process logic consistently into the diagram. And it requires a measure of modeling style as well, conventions that ensure that the process logic is unambiguous from the diagram by itself. In short, "good BPMN" requires a disciplined approach called "method and style."In this book, Bruce Silver explains which BPMN elements process modelers need to understand, in two levels, including exactly where and how to use each element. Level 1 (the Descriptive modeling subclass of BPMN 2.0) is a palette of shapes and symbols largely carried over from traditional flowcharting. Level 2 (the Analytic subclass) expands the palette to be able to describe event-triggered behavior, critical to modeling exception handling.The book explains the real meaning of BPMN's most basic concepts - like activity, process, and end state - essential to using the language correctly, and provides a step-by-step methodology for going from a blank page to a complete end-to-end BPMN model, developed from the top down in a hierarchical structure. From the top-level diagram you can see on a single page exactly how the process starts, its possible end states, what the instance represents, and communications with the Customer, service providers, and other processes. From there you can drill down to see the details of any part of the process. Thie popular first edition of this book was published in 2009 based on the draft BPMN 2.0 specification. This second edition is based on the final BPMN 2.0 specification. Although the diagram elements have changed little since the first edition, both the methodology and style sections have been completely rewritten.The second half of the book, the BPMN Implementer's Guide, is completely new. It puts the focus on the XML serialization of the diagram, for both non-executable and executable process models. It details the BPMN 2.0 metamodel and XML Schema, and describes the BPMN-I Profile, a set of serialization rules that facilitate interchange of BPMN models in the Analytic subclass between tools. It also explains how BPMN 2.0 describes execution-related details, such as process data and data mapping, services, messages, and human task assignment, illustrated with an example executable process created in Bonita Open Solution. It concludes with guidelines for implementers on how to align executable design with business-oriented top-down process modeling.The book is lavishly illustrated with over 100 BPMN diagrams, and the BPMN Implementer's Guide section contains many XML examples as well.Bruce Silver is the leading provider of BPMN training and certification. He has been providing BPMN training since early 2007 and is regarded as an authority in the field.

    Written with clarity and a dazzling intellectual passion, it is both a seminal work of modern geology and a compelling precursor to Darwinism, exploring the evidence for radical changes in climate and geography across the ages and speculating on the progressive development of life. A profound influence on Darwin, Principles of Geology also captured the imagination of contemporaries such as Melville, Emerson, Tennyson and George Eliot, transforming science with its depiction of the powerful forces that shape the natural world.

    The fruits of geology provide most of the materials that give us shelter, and most of the energy that drives our modern lives. Within the study of geology lie some of the clues to the extraordinary impact our species is going to play out on the planet, in centuries and millennia to come.In this Very Short Introduction Jan Zalasiewicz gives a brief introduction to the fascinating field of geology. Describing how the science developed from its early beginnings, he looks at some of the key discoveries that have transformed it, before delving into its various subfields, such as sedimentology, tectonics, and stratigraphy. Analyzing the geological foundations of the Earth, Zalasiewicz explains the interlocking studies of tectonics, geophysics, and igneous and metamorphic petrology and geochemistry; and describes how rocks are dated by radiometric dating. Considering the role and importance of geology in the finding and exploitation of resources (including fracking), he also discusses its place in environmental issues, such as foundations for urban structures and sites for landfill, and in tackling issues associated with climate change. Zalasiewicz concludes by discussing the exciting future and frontiers of the field, such as the exploration of the geology of Mars.ABOUT THE SERIES: The Very Short Introductions series from Oxford University Press contains hundreds of titles in almost every subject area.

    Under the bottom is the top--and the power to smash the Machine. After humanity becomes inextricably linked to the computers, a heroic couple makes a scale-ship journey beneath the smallest particles and through the largest cosmic structures, seeking a perfect world.

    The result is The Backbone of the World, an arresting exploration of America’s longest wilderness corridor, a harsh and unforgiving region inhabited by men and women whose way of life is as imperiled as the neighboring wildlife. With the brutal beauty and stark cadences of a Cormac McCarthy novel, The Backbone of the World tells the story of the last remnants of the Old West, America’s mythic landscape, where past and present are barely discernible from one another and where people’s lives are still intrinsically linked to their natural surroundings. Clifford vividly captures the challenges of life along the Divide today through portraits of memorable characters: a ranching family whose isolated New Mexico homestead has become a mecca for illegal immigrants and drug smugglers; a sheep herder struggling to make a living tending his flock in the mountains above Vail, Colorado: an old mule packer who has spent years scouring the mountains of northwest Wyoming for the downed plane of his son; a Yellowstone Park ranger on a lone crusade to protect elk and grizzly bears from illegal hunters; and a group of Blackfeet Indians in northern Montana who are fearful that a wilderness sanctuary will be lost to oil and gas development. In each of their stories, the tide of change is looming as environmental, economic, social, and political forces threaten this uniquely unfettered population. Clifford’s participatory approach offers a haunting and immediate evocation of character and geography and an unsentimental eulogy to the people whose disappearance will sever a link with the defining American pioneer spirit. Set in a world of isolated ranches, trail camps, mountain bivouacs, and forgotten hamlets, The Backbone of the World highlights the frontier values that have both ennobled and degraded us, values that symbolize the last breath of our founding character.From the Hardcover edition.

    Here you will find a brief review of the astrological basics (planets, houses, signs and aspects) and then the heart of the book - Transits - the current positions of the planets in the sky compared to one's birth chart. Outer planets are discussed in terms of their "Teacher" or "Trickster" potentials. Also addressed is the cycle of the houses and the tasks represented by each. Progressions - a day symbolically equated to a year in one's life. Thorough explanations of progressed Moon through the houses and signs, and changing angles (Midheaven and Ascendant) are presented. The Art of Synthesis - how to put it all together. Also includes an appendix with valuable information on how to look up transits and calculate secondary progressions. This practical guide to predictive astrology shows the reader how to make better life choices, with a focus on personal freedom and responsibility.

    In his hallmark friendly style, he explores the universal impact of being the right size. By examining stories ranging from Alice in Wonderland to Gulliver's Travels, he shows that humans have always been fascinated by things big and small. Why then does size always reside on the fringes of science and never on the center stage? Why do biologists and others ponder size only when studying something else--running speed, life span, or metabolism? Why Size Matters, a pioneering book of big ideas in a compact size, gives size its due by presenting a profound yet lucid overview of what we know about its role in the living world. Bonner argues that size really does matter--that it is the supreme and universal determinant of what any organism can be and do. For example, because tiny creatures are subject primarily to forces of cohesion and larger beasts to gravity, a fly can easily walk up a wall, something we humans cannot even begin to imagine doing.Bonner introduces us to size through the giants and dwarfs of human, animal, and plant history and then explores questions including the physics of size as it affects biology, the evolution of size over geological time, and the role of size in the function and longevity of living things.As this elegantly written book shows, size affects life in its every aspect. It is a universal frame from which nothing escapes.

    The subsequent investigation was a maze of politics, bizarre theories, and shrouded answers. Bill Adair, an award-winning journalist, was granted special access to the five-year inquiry by the National Transportation Safety Board (NTSB) while its investigators tried to determine if the world's most widely used commercial jet, the Boeing 737, was really safe. Their findings have had wide-ranging effects on the airline industry, pilots, and even passangers. Adair takes readers behind the scenes to show who makes decisions about airline safety--and why.

    Its tale is one riddled with jealousy, rivalry, missed opportunities and moments of genius. Piers Bizony tells the story of the young misfit New Zealander, Ernest Rutherford, who showed that the atom consisted mainly of empty space, a discovery that turned 200 years of classical physics on its head, and the brilliant Dane, Niels Bohr, who made the next great leap into the incredible world of quantum theory. Yet he and a handful of other Young Turks in this revolutionary new science weren't prepared for the shocks that Nature had up her sleeve. At the dawn of the Atomic Age, a dangerous new force was unleashed with terrifying speed...
