See What’s in the New Edition: Four case studies Addition of another co-author Examples that reflect current technology Information on Critical Path Analysis (CPA) The authors highlight where ergonomics methods fit in the design process and how to select a method appropriate for your purpose. They describe each method, supplying an overview, instructions on how to carry out an analysis, a mini bibliography, pros and cons, one or more examples, and a flow chart. They then rate each method for reliability/validity, resources, usability, and efficacy. The book then examines data from studies on training, reliability, and validity, and presents an equation that enables you to calculate approximately the financial benefits of using each method. Based on research and expertise, the book gives you the freedom to be adventurous when choosing methods and the foundation to choose the method that fits the task at hand. Written by experts, it also helps you hone your skills and put the craft of ergonomics into practice.
Description : James Tobin, award-winning author of Ernie Pyle's War and The Man He Became, has penned the definitive account of the inspiring and impassioned race between the Wright brothers and their primary rival Samuel Langley across ten years and two continents to conquer the air. For years, Wilbur Wright and his younger brother, Orville, experimented in obscurity, supported only by their exceptional family. Meanwhile, the world watched as Samuel Langley, armed with a contract from the US War Department and all the resources of the Smithsonian Institution, sought to create the first manned flying machine. But while Langley saw flight as a problem of power, the Wrights saw a problem of balance. Thus their machines took two very different paths—Langley’s toward oblivion, the Wrights’ toward the heavens—though not before facing countless other obstacles. With a historian’s accuracy and a novelist’s eye, Tobin has captured an extraordinary moment in history. To Conquer the Air is itself a heroic achievement.
