The North Carolina barrier islands, a 325-mile-long string of narrow sand islands that forms the coast of North Carolina, are one of the most beloved areas to live and visit in the United States. However, extensive barrier island segments and their associated wetlands are in jeopardy. In The Battle for North Carolina's Coast, four experts on coastal dynamics examine issues that threaten this national treasure. According to the authors, the North Carolina barrier islands are not permanent. Rather, they are highly mobile piles of sand that are impacted by sea-level rise and major storms and hurricanes. Our present development and management policies for these changing islands are in direct conflict with their natural dynamics. Revealing the urgency of the environmental and economic problems facing coastal North Carolina, this essential book offers a hopeful vision for the coast's future if we are willing to adapt to the barriers' ongoing and natural processes. This will require a radical change in our thinking about development and new approaches to the way we visit and use the coast. Ultimately, we cannot afford to lose these unique and valuable islands of opportunity. This book is an urgent call to protect our coastal resources and preserve our coastal economy.
Electronic materials provide the basis for many high tech industries that have changed rapidly in recent years. In this fully revised and updated second edition, the author discusses the range of available materials and their technological applications. Introduction to the Electronic Properties of Materials, 2nd Edition presents the principles of the behavior of electrons in materials and develops a basic understanding with minimal technical detail. Broadly based, it touches on all of the key issues in the field and offers a multidisciplinary approach spanning physics, electrical engineering, and materials science. It provides an understanding of the behavior of electrons within materials, how electrons determine the magnetic thermal, optical and electrical properties of materials, and how electronic properties are controlled for use in technological applications. Although some mathematics is essential in this area, the mathematics that is used is easy to follow and kept to an appropriate level for the reader. An excellent introductory text for undergraduate students, this book is a broad introduction to the topic and provides a careful balance of information that will be appropriate for physicists, materials scientists, and electrical engineers.
Few subjects in science are more difficult to understand than magnetism, according to Encyclopedia Britannica. However, there is a strong demand today for scientists and engineers with skills in magnetism because of the growing number of technological applications utilizing this phenomenon. This textbook responds to the need for a comprehensive introduction of the basic concepts of the science. Introduction to Magnetism and Magnetic Materials has been thoroughly revised since the first edition to include recent developments in the field. The early chapters comprise a discussion of the fundamentals of magnetism. These chapters include more than 60 sample problems with complete solutions to reinforce learning. The later chapters review the most significant recent developments in four important areas of magnetism: hard and soft magnetic materials, magnetic recording, and magnetic evaluation of materials. These later chapters also provide a survey of the most important areas of magnetic materials for practical applications. Extensive references to the principal publications in magnetism are listed at the end of each chapter, which offer the reader rapid access to more specialized literature. Students in various scientific areas will benefit from this book, including those in physics, materials science, metallurgy, and electrical engineering.
Winner of the 2013 American Educational Studies Association's 2013 Critics Choice Award! Teachers the world over are seeking creative ways to respond to the problems and possibilities generated by globalization. Many of them work with children and youth from increasingly varied backgrounds, with diverse needs and capabilities. Others work with homogeneous populations and yet are aware that their students will encounter many cultural changes in their lifetimes. All struggle with the contemporary conditions of teaching: endless top-down measures to manipulate what they do, rapid economic turns and inequality in supportive resources that affect their lives and those of their students, a torrent of media stimuli that distract educational focus, and growth as well as shifts in population. In The Teacher and the World, David T. Hansen provides teachers with a way to reconstruct their philosophies of education in light of these conditions. He describes an orientation toward education that can help them to address both the challenges and opportunities thrown their way by a globalized world. Hansen builds his approach around cosmopolitanism, an ancient idea with an ever-present and ever-beautiful meaning for educators. The idea pivots around educating for what the author calls reflective openness to new people and new ideas, and reflective loyalty toward local values, interests, and commitments. The book shows how this orientation applies to teachers at all levels of the system, from primary through university. Hansen deploys many examples to illustrate how its core value, a balance of reflective openness to the new and reflective loyalty to the known, can be cultivated while teaching different subjects in different kinds of settings. The author draws widely on the work of educators, scholars in the humanities and social sciences, novelists, artists, travellers and others from both the present and past, as well as from around the world. These diverse figures illuminate the promise in a cosmopolitan outlook on education in our time. In this pioneering book, Hansen has provided teachers, heads of school, teacher educators, researchers, and policy-makers a generative way to respond creatively to the pressure and the promise of a globalizing world.
The extent of Christ’s atoning work on the cross is one of the most divisive issues in evangelical Christianity. In The Extent of the Atonement: A Historical and Critical Review, David L. Allen makes a biblical, historical, theological, and practical case for a universal atonement. Through a comprehensive historical survey, Allen contends that universal atonement has always been the majority view of Christians, and that even among Calvinist theologians there is a considerable range of views. Marshalling evidence from Scripture and history, and critiquing arguments for a limited atonement, Allen affirms that an unlimited atonement is the best understanding of Christ’s saving work. He concludes by showing that an unlimited atonement provides the best foundation for evangelism, missions, and preaching.
