"Christopher Wanjek uses a take-no-prisoners approach in debunking the outrageous nonsense being heaped on a gullible public in the name of science and medicine. Wanjek writes with clarity, humor, and humanity, and simultaneously informs and entertains." -Dr. Michael Shermer, Publisher, Skeptic magazine; monthly columnist, Scientific American; author of Why People Believe Weird Things Prehistoric humans believed cedar ashes and incantations could cure a head injury. Ancient Egyptians believed the heart was the center of thought, the liver produced blood, and the brain cooled the body. The ancient Greek physician Hippocrates was a big fan of bloodletting. Today, we are still plagued by countless medical myths and misconceptions. Bad Medicine sets the record straight by debunking widely held yet incorrect notions of how the body works, from cold cures to vaccination fears. Clear, accessible, and highly entertaining, Bad Medicine dispels such medical convictions as: * You only use 10% of your brain: CAT, PET, and MRI scans all prove that there are no inactive regions of the brain . . . not even during sleep. * Sitting too close to the TV causes nearsightedness: Your mother was wrong. Most likely, an already nearsighted child sits close to see better. * Eating junk food will make your face break out: Acne is caused by dead skin cells, hormones, and bacteria, not from a pizza with everything on it. * If you don't dress warmly, you'll catch a cold: Cold viruses are the true and only cause of colds. Protect yourself and the ones you love from bad medicine-the brain you save may be your own.

Distance protection provides the basis for network protection in transmission systems and meshed distribution systems. This book covers the fundamentals of distance protection and the special features of numerical technology. The emphasis is placed on the application of numerical distance relays in distribution and transmission systems. This book is aimed at students and engineers who wish to familiarise themselves with the subject of power system protection, as well as the experienced user, entering the area of numerical distance protection. Furthermore it serves as a reference guide for solving application problems. For this fourth edition all contents, especially the descriptions of numerical protection devices and the very useful appendix have been revised and updated.

Distance determination is an essential technique in astronomy, and is briefly covered in most textbooks on astrophysics and cosmology. It is rarely covered as a coherent topic in its own right. When it is discussed the approach is frequently very dry, splitting the teaching into, for example, stars, galaxies and cosmologies, and as a consequence, books lack depth and are rarely comprehensive. Adopting a unique and engaging approach to the subject An Introduction to distance Measurement in Astronomy will take the reader on a journey from the solar neighbourhood to the edge of the Universe, discussing the range of distance measurements methods on the way. The book will focus on the physical processes discussing properties that underlie each method, rather than just presenting a collection of techniques. As well as providing the most compressive account of distance measurements to date, the book will use the common theme of distance measurement to impart basic concepts relevant to a wide variety of areas in astronomy/astrophysics. The book will provide an updated account of the progress made in a large number of subfields in astrophysics, leading to improved distance estimates particularly focusing on the underlying physics. Additionally it will illustrate the pitfalls in these areas and discuss the impact of the remaining uncertainties in the complete understanding of the Universes at large. As a result the book will not only provide a comprehensive study of distance measurement, but also include many recent advances in astrophysics.

This important new resource shows how a strong sense of online presence contributes to greater student satisfaction and retention. The authors explore the psychological and social aspects of online presence from both the instructor and student perspective and provide an instructional design framework for developing effective online learning. Based on solid research and extensive experience, the book is filled with suggested methods, illustrative case scenarios, and effective activities for creating, maintaining, and evaluating presence throughout an online course. «The authors have taken the mystery out of the critical concept of presence by providing the theory that supports its importance and simple techniques to make it happen. Instructors who read this book will be able to develop effective online learning communities and achieve desired learning outcomes.» —Rena M. Palloff and Keith Pratt, program directors and faculty, Teaching in the Virtual Classroom Program, Fielding Graduate University «Lehman and Conceicao blend hands-on experience, research, and a collection of practical tips to provide every online instructor with strategies for 'being there.' If you want to bring the real you into your online classes and take your online teaching to the next level, this is the book to read.» —Chip Donohue, director of distance learning, Erikson Institute «This book provides a practical and interactive model to help readers reflect on why and how they can guide online and blended learning activities, characterized by a personal 'sense of presence.'» —Alan B. Knox, professor, School of Education, University of Wisconsin-Madison

Praise for VIRTUAL TEAM SUCCESS «There's no school for this yet, but when the first is established, Virtual Team Success: A Practical Guide for Working and Leading from a Distance will certainly be the core curriculum.» —JESSICA LIPNACK AND JEFFREY STAMPS, CEO and co-founders, NetAge «Virtual Team Success is a must have for anyone managing geographically-dispersed teams. DeRosa and Lepsinger bring experience and credentials to guide us all through the labyrinth of problems that so often derail virtual teams. As our global businesses become increasingly complex, I can't imagine a more timely or better resource.» —JAY MOLDENHAUER-SALAZAR, vice president, talent management, The Gap «For global teams that want to be top-performing, Virtual Team Success should be their team handbook. It's loaded with tools, checklists, models, and practical recommendations for working and leading from a distance. This is the kind of book virtual teams really need to be successful. I've been waiting for a book like this and look forward to recommending it as a resource that can help improve the performance of our teams!» —KATHLEEN MCGUIRE, manager organizational development, Bayer Healthcare HR Global Leadership Development «Virtual teams are intended to make optimal use of expertise spread across the world, but performance excellence is the exception and mediocrity the rule. After extensive and careful study of real teams, DeRosa and Lepsinger have captured essential information, principles of operation, and tools in a highly readable volume that can help thoughtful readers elevate the performance of the teams significantly. The practical focus, collection of techniques and tools, and „how to“ tips provide an essential foundation for anyone with virtual team responsibility. The organization of the book centered around challenges, differentiators, and lessons will facilitate finding answers to any problem the team faces. The RAMP model makes it easy to focus on what's important in enabling top performance.» —MIKE BEYERLEIN, professor, Organizational Leadership, Purdue University
