With two new chapters, improved artwork, and significant updates made throughout to increase readability, the fourth edition of Audiology: Science to Practice continues to be the most comprehensive textbook for audiology and hearing science courses, as well as for health care professionals wanting a better understanding of hearing science and audiology practices. It is written in a style that makes new or difficult concepts relatively easy to understand, while still providing more coverage of hearing and vestibular science and clinical audiology than other introductory texts. Topics include information about the profession of audiology, acoustics, anatomy and physiology of the auditory and vestibular systems, preparing for the patient, otoscopy, pure-tone audiometry and speech measures, audiogram interpretations, masking, tympanometry, acoustic reflexes, wideband acoustic immittance, otoacoustic emissions, auditory brainstem responses, hearing screening, hearing aids, assistive listening aides, cochlear and other implantable devices, vestibular evaluation, descriptions of auditory and vestibular disorders, and aural rehabilitation. There is also a chapter on the roles of speech-language pathologists related to understanding and caring for persons with hearing and balance concerns. Where relevant, the material includes evidence-based practice. New to the Fourth Edition Two new chapters: Role of the Speech-Language Pathologist and Other Treatments and (Re)habilitation of Hearing and Balance Disorders Many new beautifully drawn two-color anatomy and physiology illustrations Black and white figures have been color-enhanced Several chapters were reorganized and updated to include vestibular anatomy, physiology, and vestibular disorders within the relevant auditory chapters A separate chapter on vestibular evaluation and bedside screening Many chapters expanded to provide information on environmental factors that affect the transmission of sound, signal-to-noise ratio, preparation for testing, cerumen management, assistive listening technology systems (HATS), and status of over-the-counter hearing aids Updated references and standards throughout Key Features Many illustrations than other texts to help clarify and expand on key concepts Chapters begin with a list of learning objectives and end with key references Punctuated with historical and informational side boxes An easy-to-read writing style to help students understand scientific concepts Key terms highlighted throughout with a comprehensive end-of-book glossary A PluralPlus companion website with PowerPoint lecture slides and an image bank for instructors, James Jerger's chapter on the History of Audiology, and more The authors have also created a companion study aid for students, Audiology Workbook, Fourth Edition.

Today, National Security is embroiled in the unknown, the uncertain, the unseen, and the unexpected. In the twenty-first century, failed states, rogue states, ethnic militias, and radical extremists produce transnational actors involved in global conflicts. During the 1980s, Iran used Hizballah as a surrogate terrorist organization. This was an excellent example of the transition from the traditional state-centered paradigm ordered around conventional strength between rival states to a new type of warfare practiced today. The model created from this research shows many of the conditions, activities, and events necessary to create a state-sponsored terrorist group and provides the reader with indicators that such a group is being formed. Surrogate Terrorists explores some of the analytic methodology used to understand terrorism, insurgency, asymmetric warfare, and state practice of denial and deception. It closes with examples of state-sponsored surrogate terrorist groups' centers of gravity that can be exploited.

What really sets the best managers above the rest? It's their power to build a cadre of employees who have great inner work lives -- consistently positive emotions; strong motivation; and favorable perceptions of the organization, their work, and their colleagues. The worst managers undermine inner work life, often unwittingly. As Teresa Amabile and Steven Kramer explain in The Progress Principle, seemingly mundane workday events can make or break employees' inner work lives. But it's forward momentum in meaningful work -- progress -- that creates the best inner work lives. Through rigorous analysis of nearly 12,000 diary entries provided by 238 employees in 7 companies, the authors explain how managers can foster progress and enhance inner work life every day. The book shows how to remove obstacles to progress, including meaningless tasks and toxic relationships. It also explains how to activate two forces that enable progress: (1) catalysts -- events that directly facilitate project work, such as clear goals and autonomy -- and (2) nourishers -- interpersonal events that uplift workers, including encouragement and demonstrations of respect and collegiality. Brimming with honest examples from the companies studied, The Progress Principle equips aspiring and seasoned leaders alike with the insights they need to maximize their people's performance.

Audiology Workbook, Fourth Edition is a companion study aid to the textbook, Audiology: Science to Practice, Fourth Edition. It can also serve as an appropriate supplement to other introductory audiology textbooks or class lectures. The Audiology Workbook focuses on exercises and questions in hearing and vestibular science and audiology clinical principles and procedures that are beneficial for students in an undergraduate communication science and disorders program and those in a graduate-level AuD program. It is also a great study resource for the Audiology Praxis Exam. The fourth edition is composed of an abundance of questions and activities designed to reinforce students' knowledge of concepts and procedures that are, traditionally, difficult to master. There are questions and activities on 1) properties of sound, such as drawing waveforms; calculating frequencies/periods, amplitudes, and phases, 2) auditory and vestibular anatomy and physiology of the auditory and vestibular systems, including diagrams to label, 3) procedures for obtaining pure-tone thresholds and interpreting/describing audiograms 4) masking for pure-tone and speech tests, 5) performing and interpreting speech test, tympanograms, wideband acoustic immittance, acoustic reflexes, 6) understanding and interpreting evoked physiologic responses, including OAEs, ABRs, ECochG, ENOG, VEMP, 7) clinical case studies for common hearing and balance disorders, 8) treatment, including hearing aids, implantable devices, cerumen management, tinnitus, and aural rehabilitation. The exercises are comprehensive and designed so they may be solved with relatively short answers and useful for group discussion. The popular exercises from previous editions have been retained, updated, and expanded, including those on audiogram interpretation, masking, immittance, and case studies. Comprehensive answers are also included for each chapter. New to the Fourth Edition Expanded exercises on the scientific foundations from the previous edition as well as new questions added on wavelength, resonance, decibels, signal-to-noise ratio, complex vibrations, stages of transduction through the auditory system, and psychoacoustics. Many new and figures of auditory and vestibular anatomy. New exercises related to clinical topics, including preparation for patient testing, case history, wideband acoustic immittance and evoked physiologic responses. New chapter with exercises on hearing aids, assistive listening technologies, and implantable devices. Each chapter now ends with a set of multiple-choice questions. Additional multiple-choice questions are available on the companion website.
