Download or read book Bird Census Techniques written by Colin J. Bibby and published by Academic Press. This book was released on 2012-12-02 with total page 276 pages. Available in PDF, EPUB and Kindle. Book excerpt: Wild birds are counted for a wide variety of reasons and by a bewildering array of methods. However, detailed descriptions of the techniques used and the rationale adopted are scattered in the literature, and the newcomer to bird census work or the experienced bird counter in search of a wider view, may well have difficulty in coming to grips with the subject as a whole. While not an end in itself, numerical and distributional census work is a fundamental part of many scientific and conservation studies, and one in which the application of given standards is vital if results are not to be distorted or applied in a misleading way. This book provides a concise guide to the various census techniques and to the opportunities and pitfalls which each entails. The common methods are described in detail, and illustrated through an abundance of diagrams showing examples of actual and theoretical census studies. Anyone with a bird census job to plan should be able to select the method best suited to the study at hand, and to apply it to best effect within the limits inherent in it and the constraints of the particular study. The Royal Society for the Protection of Birds and the British Trust for Ornithology have for many years pioneered the collaboration of amateurs and professionals in various census studies. Three members of their staff, each with extensive field experience, now pool the knowledge of these investigations to lay the groundwork for sound census work in future years.

Download or read book Perspectives on Global Biodiversity Scenarios and Environmental Services in the 21st Century written by Chourasia, Naveen Kumar and published by IGI Global. This book was released on 2023-11-01 with total page 309 pages. Available in PDF, EPUB and Kindle. Book excerpt: Quantitative models are increasingly being used to assess the impact of socioeconomic development pathways on biodiversity and environmental services. Regardless of the scenario, the decline of biodiversity will continue throughout the 21st century. Land-use changes drive biodiversity changes in terrestrial systems, while overfishing drives changes in marine systems, and climate change affects all realms. The loss of habitats will lead to local population decreases, and global extinctions will occur at unpredictable rates due to the lag between environmental changes and their effects. To address this, we need to focus more on the relationship between the decline of ecosystem services and the position of species responsible for that function in the trophic hierarchy. Perspectives on Global Biodiversity Scenarios and Environmental Services in the 21st Century makes biodiversity scenarios understandable, relevant, and valuable to stakeholders by using effective language and focused communication techniques. Instead of merely showing the potential effects of global change on biodiversity, scenarios should consider the feedback connecting environmental forces. Biodiversity provides numerous essential environmental services crucial to human well-being both now and in the future. The climate is a critical component of ecosystem functioning and directly and indirectly affects human health. The target audience includes biology and environmental science students and faculty, scientists, social workers who generate and collaborate on biodiversity scenarios, policymakers, and corporations with a basic science understanding.
Download or read book No Excuses written by Stephan Thernstrom and published by Simon and Schuster. This book was released on 2009-07-14 with total page 361 pages. Available in PDF, EPUB and Kindle. Book excerpt: Black and Hispanic students are not learning enough in our public schools, and their typically poor performance is the most important source of ongoing racial inequality in America today—thus, say Abigail and Stephan Thernstrom, the racial gap in school achievement is the nation's most critical civil rights issue and an educational crisis; it's no wonder that "No Child Left Behind," the 2001 revision of the Elementary and Secondary Education Act, made closing the racial gap in education its central goal. An employer hiring the typical Black high school graduate or the college that admits the average Black student is choosing a youngster who has only an eighth-grade education. In most subjects, the majority of twelfth-grade Black students do not have even a "partial mastery" of the skills and knowledge that the authoritative National Assessment of Educational Progress calls "fundamental for proficient work" at their grade. No Excuses marshals facts to examine the depth of the problem, the inadequacy of conventional explanations, and the limited impact of Title I, Head Start, and other familiar reforms. Its message, however, is one of hope: Scattered across the country are excellent schools getting terrific results with high-needs kids. These rare schools share a distinctive vision of what great schooling looks like and are free of many of the constraints that compromise education in traditional public schools. In a society that espouses equal opportunity we still have a racially identifiable group of educational have-nots—young African Americans and Latinos whose opportunities in life will almost inevitably be limited by their inadequate education. When students leave high school without high school skills, their futures—and that of the nation—are in jeopardy. With successful schools already showing the way, no decent society can continue to turn a blind eye to such racial and ethnic inequality.

Available in PDF, EPUB and Kindle. Book excerpt: In this book the authors explore the state of the art on efficiency measurement in health systems and international experts offer insights into the pitfalls and potential associated with various measurement techniques. The authors show that: - The core idea of efficiency is easy to understand in principle - maximizing valued outputs relative to inputs, but is often difficult to make operational in real-life situations - There have been numerous advances in data collection and availability, as well as innovative methodological approaches that give valuable insights into how efficiently health care is delivered - Our simple analytical framework can facilitate the development and interpretation of efficiency indicators.
Download or read book Distribution Costs and Real Exchange Rate Dynamics During Exchange rate based stabilizations written by Ariel T. Burstein and published by . This book was released on 2000 with total page 68 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper studies the role played by the distribution sector in shaping the behavior of the real exchange rate during exchange-rate-based-stabilizations. We use data for the U.S. and Argentina to document the importance of distribution margins in retail prices and disaggregated price data to study price dynamics in the aftermath of Argentina's 1991 Convertibility plan. Distribution services require local labor and land so they drive a natural wedge between retail prices in different countries. We study in detail the impact of introducing a distribution sector in an otherwise standard model of exchange-rate-based-stabilizations. We show that this simple extension improves dramatically the ability of the model to rationalize observed real exchange rate dynamics.

Download or read book International VAT GST Guidelines written by Collectif and published by OECD. This book was released on 2017-04-12 with total page 116 pages. Available in PDF, EPUB and Kindle. Book excerpt: Value Added Tax (VAT; also known as Goods and Services Tax, under the acronym GST in a number of OECD countries) has become a major source of revenue for governments around the world. Some 165 countries operated a VAT at the time of the completion of the International VAT/GST Guidelines in 2016, more than twice as many as 25 years before. As VAT continued to spread across the world, international trade in goods and services has also expanded rapidly in an increasingly globalised economy. One consequence of these developments has been the greater interaction between VAT systems, along with growing risks of double taxation and unintended non-taxation in the absence of international VAT co-ordination. The International VAT/GST Guidelines now present a set of internationally agreed standards and recommended approaches to address the issues that arise from the uncoordinated application of national VAT systems in the context of international trade. They focus in particular on trade in services and intangibles, which poses increasingly important challenges for the design and operation of VAT systems worldwide. They notably include the recommended principles and mechanisms to address the challenges for the collection of VAT on cross-border sales of digital products that had been identified in the context of the OECD/G20 Project on Base and Erosion and Profit Shifting (the BEPS Project). These Guidelines were adopted as a Recommendation by the Council of the OECD in September 2016.
