Practical Color Measurement tells you everything you need to know about the principles and limitations of computerized color measuring systems. Mathematics and optical theory are kept to a minimum, replaced by numerous real-life examples based on normal production samples, detailed tables and the practical knowledge gained by Anni Berger-Schunn through many years of professional experience and research.

In this volume, Shavelson and Webb offer an intuitive development of generalizability theory and cover a wide variety of topics such as generalizability studies with nested facets and with fixed facets, measurement error and generalizability coefficients, and decision studies with same and with different designs. Detailed illustrations, examples and exercises all serve to clearly describe the logic underlying major concepts in generalizability theory and assist readers in applying these methods when investigating the consistency of their own measurements.

The text contains detailed and complete proofs and includes instructive historical introductions to key chapters. These serve to illustrate the hurdles faced by the scholars that developed the theory, and allow the novice to approach the subject from a wider angle, thus appreciating the human side of major figures in Mathematics. The style in which topics are addressed, albeit informal, always maintains a rigorous character. The attention placed in the careful layout of the logical steps of proofs, the abundant examples and the supplementary remarks disseminated throughout all contribute to render the reading pleasant and facilitate the learning process. The exposition is particularly suitable for students of Mathematics, Physics, Engineering and Statistics, besides providing the foundation essential for the study of Probability Theory and many branches of Applied Mathematics, including the Analysis of Financial Markets and other areas of Financial Engineering.

Thousands of public relations (PR) students and professionals have relied on this authoritative text to understand the key role of research in planning and evaluating PR campaigns. Revised and expanded to reflect today's emphasis on standards-based practice, the third edition has a heightened emphasis on setting baselines, creating benchmarks, and assessing progress. Stacks presents step-by-step guidelines for using a wide range of qualitative and quantitative methods to track output, outtakes, and outcomes, and shows how to present research findings clearly to clients. Every chapter features review questions and a compelling practice problem. PowerPoint slides for use in teaching are provided at the companion website. Instructors requesting a desk copy also receive a supplemental Instructor's Manual with a test bank, suggested readings, and case studies. New to This Edition: *Chapter on standardization, moving beyond the prior edition's focus on best practices. *Chapter on different types of data sets, with attention to the advantages and disadvantages of using Big Data. *Addresses the strategic use of key performance indicators. *Covers the latest content analysis software. Pedagogical Features: *Each chapter opens with a chapter overview and concludes with review questions. *End-of-chapter practice problems guide readers to implement what they have learned in a PR project. *Appendix provides a dictionary of public relations measurement and research terms. *Supplemental Instructor's Manual and PowerPoint slides.

This is the most authoritative, complete source of test and measurement information for engineers who design and maintain fiber optic networks. This book presents measurement principles for characterizing all three basic components of a fiber optic communication system: the optical transmitter, fiber medium and optical receiver. It also covers system level measurements, and discusses the principles and limitations of current fiber optic testing equipment. It discusses testing to SONET/SDH international standards, and helps engineers choose the best approach to testing today's new erbium doped fiber amplifiers. The book provides detailed recommendations for understanding polarization states, and presents new methods for accurately characterizing the behavior of Wavelength Division Multiplexing (WDM) fiber systems. It includes detailed coverage of testing fiber in the local loop, using optical power meters and optical time domain reflectometers. It also reviews the latest state-of-the-art 10 Gb/s systems, and even faster systems on the horizon. The coverage is practical, helping professionals accurately measure and test fiber optic systems without becoming experts in theory. All fiber optic engineers working with communications applications.

How do you judge the quality of a school, a district, a teacher, a student? By the test scores, of course. Yet for all the talk, what educational tests can and can’t tell you, and how scores can be misunderstood and misused, remains a mystery to most. The complexities of testing are routinely ignored, either because they are unrecognized, or because they may be—well, complicated. Inspired by a popular Harvard course for students without an extensive mathematics background, Measuring Up demystifies educational testing—from MCAS to SAT to WAIS, with all the alphabet soup in between. Bringing statistical terms down to earth, Daniel Koretz takes readers through the most fundamental issues that arise in educational testing and shows how they apply to some of the most controversial issues in education today, from high-stakes testing to special education. He walks readers through everyday examples to show what tests do well, what their limits are, how easily tests and scores can be oversold or misunderstood, and how they can be used sensibly to help discover how much kids have learned.

Despite public perception, osteoporosis remains a widespread, devastating disease, and a very serious and costly public health threat. Early detection and treatment must be a priority for primary health care providers. Dual-energy X-ray absorptiometry (DXA) is the principal x-ray technology used to diagnose osteoporosis in its early, asymptomatic stages, to assess treatment efficacy, and to guide treatment decisions. It remains the gold standard today. A DXA Primer for the Practicing Clinician: A Case-Based Manual for Understanding and Interpreting Bone Densitometry is developed around real cases of patients’ DXA measurements. The content is derived from presentations given by the authors at a national society training course and exemplifies not only the complete body of education provided through these lectures but the full range of previously undiscussed nuances as well. This practical, easy-to-read title provides the day to day problems of DXA usage that new users may encounter and that training courses do not have time to provide in detail. The central focus of the book is the presentation of what is normal and what is problematic in the use of DXA, depicting various scenarios with real case histories of patients, their corresponding DXA images and the data that explain the problems. Unique in approach and presentation, this case-based manual will be of immense value to all practitioners -- and students – interested in providing optimal diagnosis and treatment of osteoporosis.
