How Chinese characters triumphed over the QWERTY keyboard and laid the foundation for China's information technology successes today. Chinese writing is character based, the one major world script that is neither alphabetic nor syllabic. Through the years, the Chinese written language encountered presumed alphabetic universalism in the form of Morse Code, Braille, stenography, Linotype, punch cards, word processing, and other systems developed with the Latin alphabet in mind. This book is about those encounters—in particular thousands of Chinese characters versus the typewriter and its QWERTY keyboard. Thomas Mullaney describes a fascinating series of experiments, prototypes, failures, and successes in the century-long quest for a workable Chinese typewriter. The earliest Chinese typewriters, Mullaney tells us, were figments of popular imagination, sensational accounts of twelve-foot keyboards with 5,000 keys. One of the first Chinese typewriters actually constructed was invented by a Christian missionary, who organized characters by common usage (but promoted the less-common characters for “Jesus" to the common usage level). Later came typewriters manufactured for use in Chinese offices, and typewriting schools that turned out trained “typewriter girls” and “typewriter boys.” Still later was the “Double Pigeon” typewriter produced by the Shanghai Calculator and Typewriter Factory, the typewriter of choice under Mao. Clerks and secretaries in this era experimented with alternative ways of organizing characters on their tray beds, inventing an input method that was the first instance of “predictive text.” Today, after more than a century of resistance against the alphabetic, not only have Chinese characters prevailed, they form the linguistic substrate of the vibrant world of Chinese information technology. The Chinese Typewriter, not just an “object history” but grappling with broad questions of technological change and global communication, shows how this happened.

Online, you can review the same questions plus an additional 420 case-based items related to Component B in 1) practice mode or 2) timed, exam-simulation mode with randomized tests that match the number and distribution of questions on the NBDHE. From a team of dental hygiene experts including lead editor Barbara Bennett, this Q&A resource is an excellent supplement to any NBDHE content review book! - More than 1,680 multiple-choice questions provide comprehensive practice spanning the entire NBDHE, with 1,250+ items relating to Component A — more than six times the number of questions on the actual exam! — and 420 case-based questions related to Component B. - Rationales accompany each question, fully explaining why each answer choice is either correct or incorrect and thus serving as secondary content review. - Distribution of questions matches each category on the NBDHE test specifications, ensuring that you have adequate practice for each content area. - An Evolve companion website includes all 1,250+ questions from the book plus additional case studies with color images and accompanying questions, available either in practice mode with instant feedback or in exam-simulation format with results and feedback provided at the end of the exam. - A test creator and timer on Evolve generates NBDHE-style tests that mimic the number and distribution of questions on the NBDHE and also provides realistic practice with time management during the exam. - 16 detailed case studies on Evolve, each of which includes a patient medical/dental history, completed periodontal chart, oral radiographs, clinical photographs, and 20-35 multiple-choice questions for patients in the five main categories covered on the NBDHE (adult periodontitis, pediatric, geriatric, special needs, and medically compromised). - References to text sources make it easy to review or find more information on specific topics.
