A practical guide to philanthropy at all levels of giving that seeks to educate and inspire A majority of American households give to charity in some form or another--from local donations to food banks, religious organizations, or schools, to contributions to prevent disease or protect basic freedoms. Whether you're in a position to give $1 or $1 million, every giver needs to answer the same question: How do I channel my giving effectively to make the greatest difference? In Giving Done Right, Phil Buchanan, the president of the Center for Effective Philanthropy, arms donors with what it takes to do more good more quickly and to avoid predictable errors that lead too many astray. This crucial book will reveal the secrets and lessons learned from some of the biggest givers, from the work of software entrepreneur Tim Gill and his foundation to expand rights for LGBTQ people to the efforts of a midwestern entrepreneur whose faith told him he must do something about childhood slavery in Ghana. It busts commonly held myths and challenging the idea that "business thinking" holds the answer to effective philanthropy. And it offers the intellectual frameworks, data-driven insights, tools, and practical examples to allow readers to understand exactly what it takes to make a difference.

Polarized Light and Optical Systems presents polarization optics for undergraduate and graduate students in a way which makes classroom teaching relevant to current issues in optical engineering. This curriculum has been developed and refined for a decade and a half at the University of Arizona’s College of Optical Sciences. Polarized Light and Optical Systems provides a reference for the optical engineer and optical designer in issues related to building polarimeters, designing displays, and polarization critical optical systems. The central theme of Polarized Light and Optical Systems is a unifying treatment of polarization elements as optical elements and optical elements as polarization elements. Key Features Comprehensive presentation of Jones calculus and Mueller calculus with tables and derivations of the Jones and Mueller matrices for polarization elements and polarization effects Classroom-appropriate presentations of polarization of birefringent materials, thin films, stress birefringence, crystal polarizers, liquid crystals, and gratings Discussion of the many forms of polarimeters, their trade-offs, data reduction methods, and polarization artifacts Exposition of the polarization ray tracing calculus to integrate polarization with ray tracing Explanation of the sources of polarization aberrations in optical systems and the functional forms of these polarization aberrations Problem sets to build students’ problem-solving capabilities.

In 2008, the Computer and Information Science and Engineering Directorate of the National Science Foundation asked the National Research Council (NRC) to conduct two workshops to explore the nature of computational thinking and its cognitive and educational implications. The first workshop focused on the scope and nature of computational thinking and on articulating what "computational thinking for everyone" might mean. A report of that workshop was released in January 2010. Drawing in part on the proceedings of that workshop, Report of a Workshop of Pedagogical Aspects of Computational Thinking, summarizes the second workshop, which was held February 4-5, 2010, in Washington, D.C., and focuses on pedagogical considerations for computational thinking. This workshop was structured to gather pedagogical inputs and insights from educators who have addressed computational thinking in their work with K-12 teachers and students. It illuminates different approaches to computational thinking and explores lessons learned and best practices. Individuals with a broad range of perspectives contributed to this report. Since the workshop was not intended to result in a consensus regarding the scope and nature of computational thinking, Report of a Workshop of Pedagogical Aspects of Computational Thinking does not contain findings or recommendations.
