These areas of knowledge have converged into a modern theory of epidemiology that has been slow to penetrate into textbooks, particularly at the introductory level. Epidemiology: An Introduction closes the gap. It begins with a brief, lucid discussion of causal thinking and causal inference and then takes the reader through the elements of epidemiology, focusing on the measures of disease occurrence and causal effects. With these building blocks in place, the reader learns how to design, analyze and interpret problems that epidemiologists face, including confounding, the role of chance, and the exploration of interactions. All these topics are layered on the foundation of basic principles presented in simple language, with numerous examples and questions for further thought.

    

    So it's not surprising that we persist in thinking that we're in with a chance, whether we're playing the lottery or working out the likelihood of extra-terrestrial life. In Chance, a (not entirely) random selection of the New Scientist's sharpest minds provide fascinating insights into luck, randomness, risk and probability. From the secrets of coincidence to placing the perfect bet, the science of random number generation to the surprisingly haphazard decisions of criminal juries, it explores these and many other tantalising questions.Following on from the bestselling Nothing and Question Everything, this book will open your eyes to the weird and wonderful world of chance - and help you see when some things, in fact, aren't random at all.

    The culprit--so necessary and yet the source of such upheaval--is the X chromosome, and this is its story. An enlightening and entertaining tour of the cultural and natural history of this intriguing member of the genome, "The X in Sex" traces the journey toward our current understanding of the nature of X. From its chance discovery in the nineteenth century to the promise and implications of ongoing research, David Bainbridge shows how the X evolved and where it and its counterpart Y are going, how it helps assign developing human babies their sex--and maybe even their sexuality--and how it affects our lives in infinitely complex and subtle ways. X offers cures for disease, challenges our cultural, ethical, and scientific assumptions about maleness and femaleness, and has even reshaped our views of human evolution and human nature.

    But Neil Armstrong and Sally Ride would have never made history, and humankind would not have touched the stars, if not for the men and women on the ground who lit the fuse that launched the first rockets.Enthralled as a boy by the exploits of Flash Gordon and the novels of Robert Heinlein and Arthur C. Clarke—who put the science in science fiction—James French became one of the original unsung engineers of America’s groundbreaking space program. His fascinating memoir offers an up-close-and-technical look at building, testing, and perfecting the pioneering Saturn rockets and original lunar landing module, and he shares true tales, both humorous and harrowing, of life—and near death—on the front lines of scientific exploration.If you’ve ever said, “It’s not rocket science,” you’re right. It’s rocket engineering—and here’s your chance to marvel at how it changed the world and made it possible to explore all that lies beyond Earth. James R French graduated from MIT in 1958 with a degree of BSME Specializing in Propulsion. His first job was with Rocketdyne Division of North American Aviation where he worked on developmental testing of H-1 engines and combustion devices hardware for F-1 and J-2 engines used in Saturn 5. Mr. French has also worked at TRW Systems, where he was Lead Development Test Engineer on the Lunar Module Descent Engine, and Jet Propulsion Laboratory where he was Advanced Planetary studies Manager as well as Chief Engineer for the SP-100 Space Nuclear Power System and worked on Mariners 5, 6, 7, 8, and 9; Viking 1 & 2 and Voyager 1 & 2. . In 1986, he helped found American Rocket Co., a commercial launch company.Since 1987, Mr. French has been consultant to a variety of aerospace companies, SDIO, NASA, and USAF. He has participated in various startup companies in the private space flight arena and currently consults extensively to Blue Origin. Mr. French is co-author with Dr. Michael Griffin of the best-selling text Space Vehicle Design, published by AIAA. The second edition of the book has received the Summerfield Book Award for 2008. Mr. French is a Fellow of both AIAA and the British Interplanetary Society and a 50+ year member of AIAA. He has held several Technical Committee and other posts in AIAA. Cover design by Evan Twohy

    By 15,000 BC, humans had migratedfrom northeastern Asia across the frozen Beringland bridge to the Americas. When the world warmed up and the last Ice Age came to an end,the Bering Strait refilled with water, dividing America from Eurasia. This division—with two great populations on Earth, each unaware of theater—continued until Christopher Columbus voyaged to the New World in the fifteenth century.The Great Divide compares the development of human kind in the Old World and the New between 15,000 BC and AD 1500. Watson identifies three major differences between the two worlds—climate, domesticable mammals, and hallucinogenic plants—that combined to produce very different trajectories of civilization in the two hemispheres. Combining the most up-to-date knowledge in archaeology, anthropology, geology, meteorology, cosmology, and mythology, this unprecedented, masterful study offers uniquely revealing insight into what it means to be human.

    The first was that we were still alive. . . ."In 1967, death was the constant companion of the Marines of Hotel Company, 2/5, as they patrolled the paddy dikes, mud, and mountains of the Arizona Territory southwest of Da Nang. But John Culbertson and most of the rest of Hotel Company were the same lean, fighting Marines who had survived the carnage of Operation Tuscaloosa. Hotel's grunts walked over the enemy, not around him. In graphic terms, John Culbertson describes the daily, dangerous life of a soldier fighting in a country where the enemy was frequently indistinguishable from the allies, fought tenaciously, and thought nothing of using civilians as a shield. Though he was one of the top marksmen in 1st Marine Division Sniper School in Da Nang in March 1967--a class of just eighteen, chosen from the division's twenty thousand Marines--Culbertson knew that against the VC and the NVA, good training and experience could carry you just so far. But his company's mission was to find and engage the enemy, whatever the price. This riveting, bloody first-person account offers a stark testimony to the stuff U.S. Marines are made of.

    The DOs chronicles the development of this controversial medical movement from the nineteenth century to the present. Historian Norman Gevitz describes the philosophy and practice of osteopathy, as well as its impact on medical care. From the theories underlying the use of spinal manipulation developed by osteopathy's founder, Andrew Taylor Still, Gevitz traces the movement's early success, despite attacks from the orthodox medical community, and details the internal struggles to broaden osteopathy's scope to include the full range of pharmaceuticals and surgery. He also recounts the efforts of osteopathic colleges to achieve parity with institutions granting M.D. degrees and looks at the continuing effort by osteopathic physicians and surgeons to achieve greater recognition and visibility.In print continuously since 1982, The DOs has now been thoroughly updated and expanded to include two new chapters addressing recent and current challenges and to bring the history of the profession up to the beginning of the new millennium.
