This reference guide lays out standards for each phase of a typical evaluation process: from defining purpose, to planning, designing, implementing, reporting, and learning from and using evaluation results.
There is growing recognition of the need for new approaches to the ways in which donors support accountability, but no broad agreement on what changed practice looks like. This publication aims to provide more clarity on the emerging practice.
This book examines the regulatory rules on public procurement in selected African countries and provides a comparative analysis of key regulatory issues.
This comprehensive new handbook is a one-stop engineering reference covering data converter fundamentals, techniques, and applications. Beginning with the basic theoretical elements necessary for a complete understanding of data converters, the book covers all the latest advances made in this changing field. Details are provided on the design of high-speec ADCs, high accuracy DACs and ADCs, sample-and-hold amplifiers, voltage sources and current reference,noise-shaping coding, sigma-delta converters, and much more.
Investment in health is a strategically important and often underestimated component of economic development. This study sets out a systematic approach to improving health in poor countries. For emerging countries, substantially improved health outcomes are a prerequisite to breaking out of the poverty cycle. This book on poverty and health, jointly published by the OECD and WHO, sets out the essential components of a broad-scope "pro-poor" health approach for action within the health system and beyond it. It is for development practitioners in the area of health issues.
This book is a cornerstone resource for a wide range of organizations and individuals concerned with sustainable development at national or local levels, as well as for international organizations concerned with supporting such development. Whilst the focus is on integrated strategies for sustainable development, the approaches and methods covered are equally relevant to poverty reduction, environmental and sectoral strategies, programme development and review. Agenda 21 called for all countries to develop sustainable development strategies. For such strategies to be effective there needs to be a real commitment. In every country, government at all levels, the private sector, and civil society, must work together in a true partnership, in transparent ways which enable genuine stakeholder participation. The necessary mechanisms and processes need to be coordinated to enable continuous learning and improvement. This resource book provides flexible, non-prescriptive guidance on how to develop, assess and implement national sustainable development strategies. It sets out principles and ideas on process and methods, and suggests how these can be used. It is based on an analysis of past and current practice, drawing directly from experience in both developed and developing countries. Following a discussion of the nature and challenges of sustainable development and the need for strategic responses to them, the heart of the book covers the main tasks in strategy processes. Individual chapters offer a rich range of guidance, ideas and case studies.
How can conflict-prone countries ensure better delivery of security and justice services? How can they establish structures and mechanisms which will ensure effective and accountable security and justice institutions? Although there has been ...
The operational amplifier ("op amp") is the most versatile and widely used type of analog IC, used in audio and voltage amplifiers, signal conditioners, signal converters, oscillators, and analog computing systems. Almost every electronic device uses at least one op amp. This book is Texas Instruments' complete professional-level tutorial and reference to operational amplifier theory and applications. Among the topics covered are basic op amp physics (including reviews of current and voltage division, Thevenin's theorem, and transistor models), idealized op amp operation and configuration, feedback theory and methods, single and dual supply operation, understanding op amp parameters, minimizing noise in op amp circuits, and practical applications such as instrumentation amplifiers, signal conditioning, oscillators, active filters, load and level conversions, and analog computing. There is also extensive coverage of circuit construction techniques, including circuit board design, grounding, input and output isolation, using decoupling capacitors, and frequency characteristics of passive components. The material in this book is applicable to all op amp ICs from all manufacturers, not just TI. Unlike textbook treatments of op amp theory that tend to focus on idealized op amp models and configuration, this title uses idealized models only when necessary to explain op amp theory. The bulk of this book is on real-world op amps and their applications; considerations such as thermal effects, circuit noise, circuit buffering, selection of appropriate op amps for a given application, and unexpected effects in passive components are all discussed in detail. *Published in conjunction with Texas Instruments *A single volume, professional-level guide to op amp theory and applications *Covers circuit board layout techniques for manufacturing op amp circuits.
