Before new interventions are released into disease control programmes, it is essential that they are carefully evaluated in field trials'. These may be complex and expensive undertakings, requiring the follow-up of hundreds, or thousands, of individuals, often for long periods. Descriptions of the detailed procedures and methods used in the trials that have been conducted have rarely been published. A consequence of this, individuals planning such trials have few guidelines available and little access to knowledge accumulated previously, other than their own. In this manual, practical issues in trial design and conduct are discussed fully and in sufficient detail, that Field Trials of Health Interventions may be used as a toolbox' by field investigators. It has been compiled by an international group of over 30 authors with direct experience in the design, conduct, and analysis of field trials in low and middle income countries and is based on their accumulated knowledge and experience. Available as an open access book via Oxford Medicine Online, this new edition is a comprehensive revision, incorporating the new developments that have taken place in recent years with respect to trials, including seven new chapters on subjects ranging from trial governance, and preliminary studies to pilot testing.

During the last 60 years the discipline of human factors (HF) has evolved alongside progress in engineering, technology, and business. Contemporary HF is clearly shifting towards addressing the human-centered design paradigm for much larger and complex societal systems, the effectiveness of which is affected by recent advances in engineering, science, and education. Human Factors of a Global Society: A System of Systems Perspective explores the future challenges and potential contributions of the human factors discipline in the Conceptual Age of human creativity and social responsibility. Written by a team of experts and pioneers, this book examines the human aspects related to contemporary societal developments in science, engineering, and higher education in the context of unprecedented progress in those areas. It also discusses new paradigms for higher education, including education delivery, and administration from a systems of systems perspective. It then examines the future challenges and potential contributions of the human factors discipline. While there are other books that focus on systems engineering or on a specific area of human factors, this book unifies these different perspectives into a holistic point of view. It gives you an understanding of human factors as it relates to the global enterprise system and its newly emerging characteristics such as quality, system complexity, evolving management system and its role in social and behavioral changes. By exploring the human aspects related to actual societal developments in science, the book opens a new horizon for the HF community.

Evaluation Methodology Basics introduces evaluation by focusing on the main kinds of 'big picture' questions that evaluations usually need to answer, and how the nature of such questions are linked to evaluation methodology choices. The author: shows how to identify the right criteria for your evaluation; discusses how to objectively figure out which criteria are more important than the others; and, delves into how to combine a mix of qualitative and quantitative data with 'relevant values' (such as needs) to draw explicitly evaluative conclusions.

This book addresses primary issues in evaluation in an international, a national and a long term perspective. The essays demonstrate that arguments about the nature and techniques of evaluation must entail far broader considerations than those often promoted by policy makers.

Much of the writing in Anglo-American epistemology in the twentieth century focused on the conditions for beliefs being "justified." In a book that seeks to shift the ground of debate within theory of knowledge, William P. Alston finds that the century-long search for a correct account of the nature and conditions of epistemic justification misses the point. Alston calls for that search to be suspended and for talk of epistemic justification to cease. He proposes instead an approach to the epistemology of belief that focuses on the evaluation of various "epistemic desiderata" that may be satisfied by beliefs.Alston finds that features of belief that are desirable for the goals of cognition include having an adequate basis, being formed in a reliable way, and coherence within bodies of belief. In Alston's view, a belief's being based on an adequate ground and its being formed in a reliable way, though often treated as competing accounts of justification, are virtually identical. Beyond "Justification" also contains discussions of fundamental questions about the epistemic status of principles and beliefs and appropriate responses to various kinds of skepticism.
