The Comprehensive Resource for Designing and Implementing MSG Processes As organizations strive to make the best possible decisions on critical issues such as compensation, succession planning, staffing, and outplacement, they have increasingly turned to multisource feedback (MSF) for answers. But while use of MSF (or 360-degree) systems has proliferated rapidly, understanding of its complexities has not—and many companies are moving forward with MSF amid a dangerous void of systematic research and discussion on this powerful process. The Handbook of Multisource Feedback provides the most comprehensive compendium available of current knowledge and practice in MSF. The volume's diverse group of contributors—which includes renowned academics, practitioners, and applied researchers—represents the acknowledged thought leaders in the current and future practice of MSF. Through their multiple perspectives, they identify best practices in the design and implementation of MSF processes and offer key guidelines for decision making when using MSF The book offers solid grounding in the nuts and bolts of MSF data collection and reporting, providing a process model that leads the reader step-by-step through each phase of an MSF system. It details the developmental and decision-making uses of multisource feedback, describing MSF applications for improving executive development, organization development and change, teams, performance management, personnel decision, and more. And it addresses the realities of system forces that influence MSF processes, including legal, ethical, and cross-cultural issues. The Handbook of Multisource Feedback will provide an ideal one-stop reference for practitioners, researchers, consultants, and organizational clients who need to understand the challenges of using multisource feedback.

This book describes the latest development in optical fiber devices, and their applications to sensor technology. Optical fiber sensors, an important application of the optical fiber, have experienced fast development, and attracted wide attentions in basic science as well as in practical applications. Sensing is often likened to human sense organs. Optical fiber can not only transport information acquired by sensors at high speed and large volume, but also can play the roles of sensing element itself. Compared with electric and other types of sensors, fiber sensor technology has unique merits. It has advantages over conventional bulky optic sensors, such as combination of sensing and signal transportation, smaller size, and possibility of building distributed systems. Fiber sensor technology has been used in various areas of industry, transportation, communication, security and defense, as well as daily life. Its importance has been growing with the advancement of the technology and the expansion of the scope of its application, a growth this book fully describes.

Polymer photonics is an interdisciplinary field which demands excellence both in optics (photonics) and materials science (polymer). However, theses disciplines have developed independently, and therefore the demand for a comprehensive work featuring the fundamentals of photonic polymers is greater than ever. This volume focuses on Polymer Optical Fiber and their applications. The first part of the book introduces typical optical fibers according to their classifications of material, propagating mode, and structure. Optical properties, the high bandwidth POF and transmission loss are discussed, followed by an outline on the propagating mode characteristics and how they affect the performances of the fiber. The second part of the book reviews conventional materials of POFs and gives an overview on fabrication methods. This is followed by a survey of characterization methods. Based on the characteristics of optical communication systems, the last chapter will concentrate on the many advantages of POF in link and network design. Written by a top expert in the field, this is an invaluable resource for semiconductor physicists, materials scientists, polymer chemists, electrical engineers, and those working in the semiconductor industry.

Covers the fundamental science of grinding and polishing by examining the chemical and mechanical interactions over many scale lengths Manufacturing next generation optics has been, and will continue to be, enablers for enhancing the performance of advanced laser, imaging, and spectroscopy systems. This book reexamines the age-old field of optical fabrication from a materials-science perspective, specifically the multiple, complex interactions between the workpiece (optic), slurry, and lap. It also describes novel characterization and fabrication techniques to improve and better understand the optical fabrication process, ultimately leading to higher quality optics with higher yield. Materials Science and Technology of Optical Fabrication is divided into two major parts. The first part describes the phenomena and corresponding process parameters affecting both the grinding and polishing processes during optical fabrication. It then relates them to the critical resulting properties of the optic (surface quality, surface figure, surface roughness, and material removal rate). The second part of the book covers a number of related topics including: developed forensic tools used to increase yield of optics with respect to surface quality (scratch/dig) and fracture loss; novel characterization and fabrication techniques used to understand/quantify the fundamental phenomena described in the first part of the book; novel and recent optical fabrication processes and their connection with the fundamental interactions; and finally, special techniques utilized to fabricate optics with high damage resistance. Focuses on the fundamentals of grinding and polishing, from a materials science viewpoint, by studying the chemical and mechanical interactions/phenomena over many scale lengths between the workpiece, slurry, and lap Explains how these phenomena affect the major characteristics of the optic workpiece—namely surface figure, surface quality, surface roughness, and material removal rate Describes methods to improve the major characteristics of the workpiece as well as improve process yield, such as through fractography and scratch forensics Covers novel characterization and fabrication techniques used to understand and quantify the fundamental phenomena of various aspects of the workpiece or fabrication process Details novel and recent optical fabrication processes and their connection with the fundamental interactions Materials Science and Technology of Optical Fabrication is an excellent guidebook for process engineers, fabrication engineers, manufacturing engineers, optical scientists, and opticians in the optical fabrication industry.
