    It is the only dictionary that provides concise, accurate definitions illustrated with finely detailed, hand-rendered drawings, each executed in Mr. Ching's signature style.

    We hear that nature runs rampant, seeking to destroy us through these 'natural disasters'. Science recounts a different story, however: disasters are not the consequence of natural causes; they are the consequence of human choices and decisions. we put ourselves in harm's way; we fail to take measures which we know would prevent disasters, no matter what the environment does.This can be both hard to accept, and hard to unravel. A complex of factors shape disasters. They arise from the political processes dictating where and what we build, and from social circumstances which create and perpetuate poverty and discrimination. They develop from the social preference to blame nature for the damage wrought, when in fact events such as earthquakes and storms are entirely commonplace environmental processes We feel the need to fight natural forces, to reclaim what we assume is ours, and to protect ourselves from what we perceive to be wrath from outside our communities. This attitude distracts us from the real causes of disasters: humanity's decisions, as societies and as individuals. It stops us accepting the real solutions to disasters: making better decisions.This book explores stories of some of our worst disasters to show how we can and should act to stop people dying when nature unleashes its energies. The disaster is not the tornado, the volcanic eruption, or climate change, but the deaths and injuries, the loss of irreplaceable property, and the lack and even denial of support to affected people, so that a short-term interruption becomes a long-term recovery nightmare. But we can combat this, as Kelman shows, describing inspiring examples of effective human action that limits damage, such as managing flooding in Toronto and villages in Bangladesh, or wildfire in Colorado.Throughout, his message is clear: there is no such thing as a natural disaster. The disaster lies in our inability to deal with the environment and with ourselves.

    It has made countless new businesses possible and presents a massive opportunity for large enterprises to innovate like startups and retire decades of technical debt. But making the most of the cloud requires much more from enterprises than just a technology change. Stephen Orban led Dow Jones’s journey toward digital agility as their CIO and now leads AWS’s Enterprise Strategy function, where he helps leaders from the largest companies in the world transform their businesses. As he demonstrates in this book, enterprises must re-train their people, evolve their processes, and transform their cultures as they move to the cloud. By bringing together his experiences and those of a number of business leaders, Orban shines a light on what works, what doesn’t, and how enterprises can transform themselves using the cloud.

    Publilius Syrus, Moral Sayings We've been very fortunate to receive fantastic feedback from our readers during the last four years, since the first edition of How to Solve It: Modern Heuristics was published in 1999. It's heartening to know that so many people appreciated the book and, even more importantly, were using the book to help them solve their problems. One professor, who published a review of the book, said that his students had given the best course reviews he'd seen in 15 years when using our text. There can be hardly any better praise, except to add that one of the book reviews published in a SIAM journal received the best review award as well. We greatly appreciate your kind words and personal comments that you sent, including the few cases where you found some typographical or other errors. Thank you all for this wonderful support.

    An examination of resultant forces and resolved components, systematic analysis of trusses, moment of inertia calculation, velocity ratio and various types of motion in dynamics are among the topics discussed.

    This edition has been updated to account for recent developments in the field such as: The emergence of mixed methods approaches Increased use of internet research More frequent use of methods such as triangulation and focus groups Developments in research ethics Written for anyone undertaking a small-scale research project, either as part of an academic course or as part of their professional development, this book provides: A clear, straightforward introduction to data collection methods and data analysis Explanations of the key decisions researchers need to take, with practical advice on how to make appropriate decisions Essential checklists to guide good practice This book is perfect for the first-time researcher looking for guidance on the issues they should consider and traps they should avoid when embarking on a social research project.

    This book gives you a solid understanding of statistics without being too simple, yet without the numbing complexity of most college texts. You get a firm grasp of the fundamentals and a hands-on understanding of how to apply them before moving on to the more advanced material that follows. Each chapter presents you with easy-to-follow descriptions illustrated by graphics, formulas, and plenty of solved examples. Before you know it, you'll learn to apply statistical reasoning and statistical techniques, from basic concepts of probability and hypothesis testing to multivariate analysis. Organized into four distinct sections, Statistics in a Nutshell offers you:Introductory material: Different ways to think about statistics Basic concepts of measurement and probability theoryData management for statistical analysis Research design and experimental design How to critique statistics presented by others Basic inferential statistics: Basic concepts of inferential statistics The concept of correlation, when it is and is not an appropriate measure of association Dichotomous and categorical data The distinction between parametric and nonparametric statistics Advanced inferential techniques: The General Linear Model Analysis of Variance (ANOVA) and MANOVA Multiple linear regression Specialized techniques: Business and quality improvement statistics Medical and public health statistics Educational and psychological statistics Unlike many introductory books on the subject, Statistics in a Nutshell doesn't omit important material in an effort to dumb it down. And this book is far more practical than most college texts, which tend to over-emphasize calculation without teaching you when and how to apply different statistical tests. With Statistics in a Nutshell, you learn how to perform most common statistical analyses, and understand statistical techniques presented in research articles. If you need to know how to use a wide range of statistical techniques without getting in over your head, this is the book you want.

    The book covers the fundamental aspects of analysis and design, and also discusses practical requirements such as safety, feasibility, and economy of structural elements. It is hoped that the text would also serve as an introduction to postgraduate students. Practicing civil engineers and consultants who need a review of current practice and current IS specifications will also find it useful as a reference.

    Written for a senior-level course, this engineering textbook presents the concepts of feedback control system theory as they have been developed in the frequency and time domains, discussing such topics as robust control systems, state variable models, computer control systems, internal model contro

    Adam Bascom trips over a body in Gressington churchyard, he never imagines it will change the whole direction of his life. As a recently-qualified physician trying to establish a practice in a small market town in north Norfolk, Adam should be devoting all his energy to his business. But it soon becomes clear that the authorities are intent on making sure the death is accepted as an accident and refuse any deeper investigation. Adam’s curiosity and sense of justice cannot accept this. He knows there are many unanswered questions about the death, but he has no standing that would allow him to become involved formally. Instead, he uses friends, old and new, unexpected contacts and even his own mother to help him get to the truth. Set against the turbulence of late-Georgian England, a country on the brink of war with Revolutionary France, the book reveals a land where spies keep constant watch on everyone the government deems ‘undesirable’, religion is polarised between the established church and a mass of dissenting sects, and the perennial ‘Irish question’ has at last spilled over into outright terrorism. Bad weather, poor harvests and enclosure have driven many people in the countryside into abject poverty. Only the smugglers along the coast offer regular and highly-paid ‘work’ helping to unload contraband. Yet here too, the Revenue’s Riding Officers, backed up by troops of dragoons, are waging an increasingly successful campaign to stamp out the major gangs. Adam must thread his way through all of this, encountering many new demands along the way, from a family torn apart by religious bigotry, and a teenage thief turned informer, to a secret section of The Alien Office, a government department dedicated to keeping a close eye on anyone likely to prove a threat to the realm. As he becomes more and more essential to the government’s efforts to combat internal dissension and prepare for war, Adam finds he must draw on all his medical and personal skills to bring the case to a successful conclusion.
