In this book on Fundamentals of Mass Determination, the definition and dissemination of units of mass is explained, starting with an introduction to metrology and mass determination. Establishing a mass scale requires corresponding mass standards and mass comparators. The metrological requirements for weighing instruments, weight pieces, and measuring conditions are explained and discussed based on international directives and applicable legal regulations. International directives and institutions are striving towards the worldwide uniform implementation of these requirements. Processes used to determine density and volume are described to the extent that they apply to mass determination. Calculating measurement uncertainty entails taking into consideration the effect of influence variables on mass determination. An overview of this topic is provided to make it easier to determine and specify measurement uncertainty in practice, while additional information in the form of tables, illustrations, and literature references allow the reader to study mass metrology further.
This Dictionary of Weighing Terms is a comprehensive practical guide to the terminology of weighing for all users of weighing instruments in industry and science. It explains more than 1000 terms of weighing technology and related areas; numerous illustrations assist understanding. The Dictionary of Weighing Terms is a joint work of the German Federal Institute of Physics and Metrology (PTB) and METTLER TOLEDO, the weighing instruments manufacturer. Special thanks go to Peter Brandes, Michael Denzel, and Dr. Oliver Mack of PTB, and to Richard Davis of BIPM, who with their technical knowledge have contributed to the success of this work. The Dictionary contains terms from the following fields: fundamentals of weighing, application and use of weighing instruments, international standards, legal requirements for weighing instruments, weighing accuracy. An index facilitates rapid location of the required term. The authors welcome suggestions and corrections at www.mt.com/w eighing-terms. Braunschweig (DE) and Greifensee (CH), The Authors Summer 2009 Foreword Since its founding in 1875, the International Bureau of Weights and Measures (BIPM) has had a unique role in mass metrology. The definition of the kilogram depends on an artefact conserved and used within our laboratories. The mass embodied in this - tefact defines the kilogram, and this information is disseminated throughout the world to promote uniformity of measurements. Although the definition of the kilogram may change in the re- tively near future, reflecting the success of new technologies and new requirements, the task of ensuring world-wide uniformity of mass measurements will remain.
Reinvigorating today’s schools with Critical, Creative and Collaborative thinking Critical, creative and collaborative thinking should be at the centre of all 21st century teaching and learning. Creating Thinking Classrooms is loaded with examples, stories and strategies for reinvigorating schools with this quality thinking. Written for leaders who support teachers, this guide treats educational change as a process of renovation, rather than process of revolution, and emphasizes building upon, refining and sustaining the many good things happening in today’s schools. Practical and user-friendly, it emphasizes five key principles for learning and teaching: Engaging students Sustaining inquiry Nurturing self-regulated learners Creating assessment-rich learning Enhancing learning through digital technology As a balanced and reasoned response to the challenges and opportunities facing schools, this book separates the rhetoric of school reform from reality by analyzing what’s actually happening and offering a plan educators can use. Recapture the fundamentals of classroom learning with a practical and powerful roadmap charting the way forward. As a principal and community superintendent, I observed firsthand how transformational the work of Garfield Gini-Newman and Roland Case is in the school community, and on a systemic level, in the school community, and on a systemic level. Creating Thinking Classrooms takes theory and research and places it directly into the hands of practitioners by offering thoughtful and immediately-useful strategies. Not only does this work transform engagement and achievement, but it also transforms thinking for both teachers and their students. Teaching and learning go from passive acquisition of information to active, purposeful, and deliberate interaction with the curriculum. It is a must-read! Ursula A. Hermann, Ph.D, retired principal and community superintendent Montgomery County Public Schools What impresses me most about Creating Thinking Classrooms is the notion of framing the retooling of schools as renovation or reinvigoration rather than as revolution. Too many seem to ignore that there are many good things worth preserving in our schools and others that need to be reframed or recast to give them greater currency. This book builds on what has worked and makes it better. The message – being purposeful and patiently focused on long-term success – is a powerful one that needs to be heard above the din.

Delta Theory establishes the foundation for a true scientific applied psychology, a theory of how human influence induces change in others. Delta Theory is unified and universal, applying to all cultures, historical periods and goals for change. It integrates concepts and research from psychology, sociology, anthropology, evolution theory, philosophy, psychoneurology, cognitive science and cultural-historical-activity theory. Yet Delta Theory is clear, economical and elegant, with a full exposition of tactics for its practices. Rich examples are drawn from professional practices, but also from the creation and operations of criminals, healing ceremonies of indigenous peoples, and cross-species comparisons. This book ultimately seeks to describe how influence works, how it could be improved and how it can be resisted.
Look in his eyes", opponent Dominique Wilkins once said of Larry Bird, "and you see a killer". It was that uncompromising competitiveness that marked Bird's storied career as he led the Boston Celtics to three NBA world championships in the 1980s. The same unconquerable hunger to win has been captured in this special collection of dramatic work from longtime Boston sports photographer Steve Lipofsky, supported by an insightful essay from veteran NBA writer Roland Lazenby. Bird, Portrait of a Competitor, pays tribute to an immensely popular athlete who came from a humble Indiana background on his way to defining the essence of basketball dedication.
