  An in-depth look at the past, present, and future of China’s military.   When Mao Zedong proclaimed the People’s Republic of China in 1949, China was a poor and wrecked society after years of continuous wars. For centuries, in fact, China had been seen as a sort of plunder-zone to be invaded, and then a backwater until the late 1980s—when domestic policy brought about monumental changes. The result is that China has grown to be the second largest economy in the world, and its military has grown proportionately.   Successive decades of economic growth have transformed China—in addition to the weapons revolution during the computer age—so that the People’s Liberation Army (PLA) has become a modern fighting force. No longer having to rely on massed infantry attacks, it now features a formidable arsenal, including nuclear submarines, ICBMs, stealth fighters, and modern battle tanks. Perhaps ominously for other maritime powers, the Chinese have also focused on beyond-the-horizon missile technology, as well as antiaircraft systems, and have explored the possibilities of cyber-warfare.   What is today’s PLA really like? What are its traditions and histories, and how is it armed and equipped? How does it recruit and train? This book describes some of the lesser-known battles and wars the Chinese have undertaken and the development of their key weapons systems. The United States, having opened the door to drone warfare, has had an attentive audience for such technologies in Beijing. The last chapter provides thoughts on how the Chinese view matters of security. It is not yet known whether foreign powers can still enforce their territorial wills on China—but future attempts will meet an increased challenge.

  Surviving Galeras

  This true, up-close account of a volcano’s eruption “artfully blends science writing and history with pure, heart-pounding action” (Mark Bowden, bestselling author of Black Hawk Down).   In 1993, Stanley Williams, an eminent volcanologist, was standing on top of a Colombian volcano called Galeras when it erupted, killing six of his colleagues instantly. As Williams tried to escape the blast, he was pelted with white-hot projectiles traveling faster than bullets. Within seconds he was cut down, his skull fractured, his right leg almost severed, his backpack aflame. Williams lay helpless and near death on Galeras’s flank until two brave women—friends and fellow volcanologists—mounted an astonishing rescue effort to carry him safely off the mountain.  Surviving Galeras is both a harrowing first-person account of an eruption and its aftermath, and a look at the fascinating, high-risk world of volcanology, exploring the profound impact volcanoes have had on the earth’s landscapes and civilizations.   Even with improved, highly-sensitive measuring tools and protective equipment, at least one volcanologist, on average, dies each year. This book reveals how Williams and his fellow scientist-adventurers continue to unveil the enigmatic and miraculous workings of volcanoes and piece together methods to predict their actions—potentially saving many human lives.   “I thoroughly enjoyed this excellent book . . . [A] riveting story.” —Dava Sobel, author of The Glass Universe   “Popular science at its best.” —The New York Times   “[A] page-turner.” —Booklist

  Human Errors - A Panorama of Our...

  We humans like to think of ourselves as highly evolved creatures. But if we are supposedly evolution's greatest creation, why do we have such bad knees? Why do we catch head colds so often—two hundred times more often than a dog does? How come our wrists have so many useless bones? Why is the vast majority of our genetic code pointless? And are we really supposed to swallow and breathe through the same narrow tube? Surely there's been some kind of mistake. 
  As professor of biology Nathan H. Lents explains in Human Errors, our evolutionary history is nothing if not a litany of mistakes, each more entertaining and enlightening than the last. The human body is one big pile of compromises. But that is also a testament to our greatness: as Lents shows, humans have so many design flaws precisely because we are very, very good at getting around them. 
  A rollicking, deeply informative tour of humans' four billion year long evolutionary saga, Human Errors both celebrates our imperfections and offers an unconventional accounting of the cost of our success.

The emphasis throughout is on understanding their original purpose and on revealing how relevant they are for researchers today. Compelling insights into individual lives and communities in the past can be gleaned from them, and they are especially useful when they are combined with other major sources, such as the census.Your Ancestors' Parish Records is an excellent introduction to this key area of family and local history research  it is a book that all family and local historians should have on their shelf.

  Managing Cybersecurity Risk -...

  The first edition, published November 2016, was targeted at the directors and senior managers of SMEs and larger organisations that have not yet paid sufficient attention to cybersecurity and possibly did not appreciate the scale or severity of permanent risk to their businesses. The book was an important wake-up call and primer and proved a significant success, including wide global reach and diverse additional use of the chapter content through media outlets. The new edition, targeted at a similar readership, will provide more detailed information about the cybersecurity environment and specific threats. It will offer advice on the resources available to build defences and the selection of tools and managed services to achieve enhanced security at acceptable cost.  A content sharing partnership has been agreed with major technology provider Alien Vault and the 2017 edition will be a larger book of approximately 250 pages.
