This book is an introduction to the mathematical theory of design for articulated mechanical systems known as linkages. The focus is on sizing mechanical constraints that guide the movement of a work piece, or end-effector, of the system. The function of the device is prescribed as a set of positions to be reachable by the end-effector; and the mechanical constraints are formed by joints that limit relative movement. The goal is to find all the devices that can achieve a specific task. Formulated in this way the design problem is purely geometric in character. Robot manipulators, walking machines, and mechanical hands are examples of articulated mechanical systems that rely on simple mechanical constraints to provide a complex workspace for the end- effector. The principles presented in this book form the foundation for a design theory for these devices. The emphasis, however, is on articulated systems with fewer degrees of freedom than that of the typical robotic system, and therefore, less complexity. This book will be useful to mathematics, engineering and computer science departments teaching courses on mathematical modeling of robotics and other articulated mechanical systems. This new edition includes research results of the past decade on the synthesis of multi loop planar and spherical linkages, and the use of homotopy methods and Clifford algebras in the synthesis of spatial serial chains. One new chapter on the synthesis of spatial serial chains introduces numerical homotopy and the linear product decomposition of polynomial systems. The second new chapter introduces the Clifford algebra formulation of the kinematics equations of serial chain robots. Examples are use throughout to demonstrate the theory.

By one analysis, a 12 percent annual increase in data processing budgets for U.S. corporations has yielded annual productivity gains of less than 2 percent. Why? This timely book provides some insights by exploring the linkages among individual, group, and organizational productivity. The authors examine how to translate workers' productivity increases into gains for the entire organization, and discuss why huge investments in automation and other innovations have failed to boost productivity. Leading experts explore how processes such as problem solving prompt changes in productivity and how inertia and other characteristics of organizations stall productivity. The book examines problems in productivity measurement and presents solutions. Also examined in this useful book are linkage issues in the fields of software engineering and computer-aided design and why organizational downsizing has not resulted in commensurate productivity gains. Important theoretical and practical implications contribute to this volume's usefulness to business and technology managers, human resources specialists, policymakers, and researchers.

Employee-Organization Linkages: The Psychology of Commitment, Absenteeism, and Turnover summarizes the theory and research on employee-organization linkages, including the processes through which employees become linked to work organizations, the quality of such linkages, and how linkages are weakened or severed. The text identifies the determinants of employee commitment, absenteeism, and turnover, as well as their consequences for the individual, work groups, and the larger organization. The book also presents conceptual models on how employees become committed to, decide to be absent from, and decide to leave their organizations. Human resource practitioners, managers, employers, and industrial psychologists will find the book very informative and insightful.
