We have come to know that our ability to survive and grow as a nation to a very large degree depends upon our scientific progress. Moreover, it is not enough simply to keep 1 abreast of the rest of the world in scientific matters. We must maintain our leadership. President Harry Truman spoke those words in 1950, in the aftermath of World War II and in the midst of the Cold War. Indeed, the scientific and engineering leadership of the United States and its allies in the twentieth century played key roles in the successful outcomes of both World War II and the Cold War, sparing the world the twin horrors of fascism and totalitarian communism, and fueling the economic prosperity that followed. Today, as the United States and its allies once again find themselves at war, President Truman’s words ring as true as they did a half-century ago. The goal set out in the Truman Administration of maintaining leadership in science has remained the policy of the U. S. Government to this day: Dr. John Marburger, the Director of the Office of Science and Technology (OSTP) in the Executive Office of the President, made remarks to that effect during his 2 confirmation hearings in October 2001. The United States needs metrics for measuring its success in meeting this goal of maintaining leadership in science and technology. That is one of the reasons that the National Science Foundation (NSF) and many other agencies of the U. S.
This handbook provides an overview of physical, chemical and biological methods used to analyze soils and plant tissue using an ecosystem perspective. The current emphasis on climate change has recognized the importance of including soil carbon as part of our carbon budgets. Methods to assess soils must be ecosystem based if they are to have utility for policy makers and managers wanting to change soil carbon and nutrient pools. Most of the texts on soil analyis treat agriculture and not forest soils and these methods do not transfer readily to forests because of their different chemistry and physical properties. This manual presents methods for soil and plant analysis with the ecosystem level approach that will reduce the risk that poor management decisions will be made in forests. This manual was intended for the instructors that teach students soil and plant analyses; however it can also be used by the research laboratories and by environmental scientists. The laboratory procedures in this manual are outlined in easy-to-follow steps and frequently accompanied with examples of calculations, questions to answer, and also a blank data sheet to use. These methods used in this manual can be used on soil and plant tissues found in agricultural, horticulture, forestry, urban, and natural lands.
Computer Architecture: A Quantitative Approach, Sixth Edition has been considered essential reading by instructors, students and practitioners of computer design for over 20 years. The sixth edition of this classic textbook from Hennessy and Patterson, winners of the 2017 ACM A.M. Turing Award recognizing contributions of lasting and major technical importance to the computing field, is fully revised with the latest developments in processor and system architecture. The text now features examples from the RISC-V (RISC Five) instruction set architecture, a modern RISC instruction set developed and designed to be a free and openly adoptable standard. It also includes a new chapter on domain-specific architectures and an updated chapter on warehouse-scale computing that features the first public information on Google's newest WSC. True to its original mission of demystifying computer architecture, this edition continues the longstanding tradition of focusing on areas where the most exciting computing innovation is happening, while always keeping an emphasis on good engineering design. - Winner of a 2019 Textbook Excellence Award (Texty) from the Textbook and Academic Authors Association - Includes a new chapter on domain-specific architectures, explaining how they are the only path forward for improved performance and energy efficiency given the end of Moore's Law and Dennard scaling - Features the first publication of several DSAs from industry - Features extensive updates to the chapter on warehouse-scale computing, with the first public information on the newest Google WSC - Offers updates to other chapters including new material dealing with the use of stacked DRAM; data on the performance of new NVIDIA Pascal GPU vs. new AVX-512 Intel Skylake CPU; and extensive additions to content covering multicore architecture and organization - Includes "Putting It All Together" sections near the end of every chapter, providing real-world technology examples that demonstrate the principles covered in each chapter - Includes review appendices in the printed text and additional reference appendices available online - Includes updated and improved case studies and exercises - ACM named John L. Hennessy and David A. Patterson, recipients of the 2017 ACM A.M. Turing Award for pioneering a systematic, quantitative approach to the design and evaluation of computer architectures with enduring impact on the microprocessor industry
Since its opening in the 1920s, Chicago's North Michigan Avenue has been one of the city's most prestigious commerical corridors, lined by some of its most architecturally distinctive business, residential, and hotel buildings. Planned by Daniel Burnham in 1909, the avenue became the principal connecting link between downtown and the wealthy, residential "Gold Coast" north of the Loop. Some thirty buildings were constructed along its path in the ten-year period before the Depression, an urban expansion comparable in significance to that of Pennsylvania and Park Avenues. John W. Stamper traces the complex development of North Michigan Avenue from the 1880s to the 1920s building boom that solidified its character and economic base, describing the initiation of the planning process by private interests to its execution aided by the city's powerful condemnation and taxation proceedings. He focuses on individual buildings constructed on the avenue, including the Renaissance- and Gothic-inspired Wrigley Building, Tribune Tower, and Drake Hotel, and places them within the context of factors governing their construction—property ownership, financing, zoning laws, design theory, and advertising. Stamper compares this stylistically diverse mixture of low- and high-rise structures with earlier, rejected planning proposals, all of which had prescribed a uniformly designed, European-like avenue of continuous cornice heights, consistent facade widths, and complementary stylistic features. He analyzes the drastically different character the avenue took by 1930, with high-rise towers reaching thirty stories and beyond, in terms of the clash among economic, political, and architectural interests. His argument—that the discrepancies between the rejected plans and reality illustrate the developers' choice of economic return on their investment over aesthetic community—is extended through to the present avenue and the virtual disregard of the urban qualities proposed at its inception. Generously illustrated, with an epilogue condensing the avenue's history between the end of World War II and the present, this is an exhaustive account of an important topic in the history of modern architecture and city planning.
Ecosystem management has gained widespread visibility as an approach to the management of land to achieve sustainable natural resource use. Despite widespread interest in this emerging management paradigm, Ecosystems: Balancing Science with Management is the first book to directly propose approaches for implementing ecosystem management, give examples of viable tools, and discuss the potential implications of implementing an ecosystem approach. These ideas are framed in a historical context that examines the disjunction between ecological theory, environmental legislation and natural resources management.
