Play is a paradox. Why would the young of so many species--the very animals at greatest risk for injury and predation--devote so much time and energy to an activity that by definition has no immediate purpose? This question has long puzzled students of animal behavior, and has been the focus of considerable empirical investigation and debate. In this first comprehensive and state-of-the-art review of what we have learned from decades of research on exploration and play in children and animals, Power examines the paradox from all angles. Covering solitary activity as well as play with peers, siblings, and parents, he considers the nature, development, and functions of play, as well as the gender differences in early play patterns. A major purpose is to explore the relevance of the animal literature for understanding human behavior. The nature and amount of children's play varies significantly across cultures, so the author makes cross-cultural comparisons wherever possible. The scope is broad and the range multidisciplinary. He draws on studies by developmental researchers in psychology and other fields, ethologists, anthropologists, sociologists, sociolinguists, early childhood educators, and pediatricians. And he places research on play in the context of research on such related phenomena as prosocial behavior and aggression. Finally, Power points out directions for further inquiry and implications for those who work with young children and their parents. Researchers and students will find Play and Exploration in Children and Animals an invaluable summary of controversies, methods, and findings; practitioners and educators will find it an invaluable compendium of information relevant to their efforts to enrich play experiences.
Continuing a best-selling tradition, the third edition of Quality by Experimental Design uses the same easy-to-read and understand format that made the previous two editions so popular with newcomers and experienced readers alike. Completely revised and revamped, the third edition has lost none of the features that made each of the previous editions bestsellers in their own right. Written in Thomas Barker's trademark, conversational style, the third edition includes new topics on inference, more realistic practice problems, examples using Minitab®, and a large dose of Robust Design philosophy and methods. Barker integrates the Robust Design, sometimes known as the Taguchi approach, as a natural part of the design effort and establishes a criterion for measurement variables. He provides step-by-step guides to the Minitab software that give you the ability to apply the concepts in practical applications and includes easy to use experimental design templates. The author presents the mathematical aspects of statistical experimental design in an intuitive rather than a theoretical manner. Emphasizing both the philosophy and the techniques for setting up experiments, the book shows you how to achieve increased efficiency, timely accomplishment of goals, visualization through graphical and numerical representation, and control of the experiment through careful planning. Those new to QED will find some of the most powerful ideas in scientific investigation and engineering understanding in this book. Seasoned QED'ers will appreciate the new insight it offers and timely reviews of subjects in which they may have become a bit rusty.

The mysterious Unipolar Dynamo, so simple that even the earth's core has one, so powerful that it forges metal alloy billets and launches a rail gun! This handbook has all the history, operating principles, practical construction details, and pictures of Faraday disk/unipolar/homopolar generators. Investigating the Paulsen UFO story and the DePalma claims of overunity, the author began an earnest scientific endeavour in 1980 to build and test a homopolar generators (HPG) for the elusive 'back torque' which had never been measured before in a one-piece HPG. This project helped to complete his Master's Degree in Physics at SUNY Buffalo. What does the torque push against when the magnet spins with the disk? How can the back torque or armature reaction be diminished or counteracted? These and other burning questions are answered in the only book of its kind on the subject of homopolar generators.

In a dynamic computing environment, such as the Grid, resource management plays a crucial role for making distributed resources available on-demand to anyone from anywhere at any time without undermining the resource autonomy; this becomes an art when dealing with heterogeneous resources distributed under multiple trust domains spanning across the Internet. Today Grid execution environments provide abstract workflow descriptions that need a dynamic mapping to actual deployments; this further accentuates the importance of resource management in the Grid. This monograph renders boundaries of the Grid resource management, identifies research challenges and proposes new solutions with innovative techniques for on-demand provisioning, automatic deployments, dynamic synthesis, negotiation-based advance reservation and capacity planning of Grid resources. The Grid capacity planning is performed with multi-constrained optimized resource allocations by modelling resource allocation as an on-line strip packing problem and introducing a new solution that optimizes resource utilization and QoS while generating contention-free solutions. On-demand resource provisioning becomes possible by simplifying abstract resource descriptions independent from the concrete installations. The book further explains the use of the semantic web technologies in the Grid to specify explicit definitions and unambiguous machine interpretable resource descriptions for intelligent resource matching and synthesis; the synthesis process generates new compound resources with aggregated capabilities and prowess. The newly introduced techniques haven been developed and integrated in ASKALON Grid application development and runtime environment, deployed in the Austrian Grid, and demonstrated through well performed experiments.
