Well-chosen negative legal proof rules can be useful procedural safeguards. They existed in both pre-modern and modern criminal procedures.

It explains why it can be important to make this evidence explicit, and describes how to take such evidence into account in the evidence appraisal process. In addition, it develops procedures for seeking evidence of mechanisms, for evaluating evidence of mechanisms, and for combining this evaluation with evidence of association in order to yield an overall assessment of effectiveness. Evidence-based medicine seeks to achieve improved health outcomes by making evidence explicit and by developing explicit methods for evaluating it. To date, evidence-based medicine has largely focused on evidence of association produced by clinical studies. As such, it has tended to overlook evidence of pathophysiological mechanisms and evidence of the mechanisms of action of interventions. The book offers a useful guide for all those whose work involves evaluating evidence in the health sciences, including those who need to determine the effectiveness of health interventions and those who need to ascertain the effects of environmental exposures.

The first edition of Statistics and the Evaluation of Evidence for Forensic Scientists established itself as a highly regarded authority on this area. Fully revised and updated, the second edition provides significant new material on areas of current interest including: Glass Interpretation Fibres Interpretation Bayes’ Nets The title presents comprehensive coverage of the statistical evaluation of forensic evidence. It is written with the assumption of a modest mathematical background and is illustrated throughout with up-to-date examples from a forensic science background. The clarity of exposition makes this book ideal for all forensic scientists, lawyers and other professionals in related fields interested in the quantitative assessment and evaluation of evidence. 'There can be no doubt that the appreciation of some evidence in a court of law has been greatly enhanced by the sound use of statistical ideas and one can be confident that the next decade will see further developments, during which time this book will admirably serve those who have cause to use statistics in forensic science.' D.V. Lindley

"What Counts as Credible Evidence in Applied Research and Evaluation Practice? is the first book of its kind to define and place into greater perspective the meaning of evidence for evaluation professionals and applied researchers. Editors Stewart I. Donaldson, Christina A. Christie, and Melvin M. Mark provide observations about the diversity and changing nature of credible evidence, include lessons from their own applied research and evaluation practice, and suggest ways in which practitioners might address the key issues and challenges of collecting credible evidence." "This book is appropriate for a wide range of courses, including Introduction to Evaluation Research, Research Methods, Evaluation Practice, Program Evaluation, Program Development and Evaluation, and evaluation courses in Social Work, Education, Public Health, and Public Policy."--BOOK JACKET.

In 1992 the National Research Council issued DNA Technology in Forensic Science, a book that documented the state of the art in this emerging field. Recently, this volume was brought to worldwide attention in the murder trial of celebrity O. J. Simpson. The Evaluation of Forensic DNA Evidence reports on developments in population genetics and statistics since the original volume was published. The committee comments on statements in the original book that proved controversial or that have been misapplied in the courts. This volume offers recommendations for handling DNA samples, performing calculations, and other aspects of using DNA as a forensic toolâ€"modifying some recommendations presented in the 1992 volume. The update addresses two major areas: Determination of DNA profiles. The committee considers how laboratory errors (particularly false matches) can arise, how errors might be reduced, and how to take into account the fact that the error rate can never be reduced to zero. Interpretation of a finding that the DNA profile of a suspect or victim matches the evidence DNA. The committee addresses controversies in population genetics, exploring the problems that arise from the mixture of groups and subgroups in the American population and how this substructure can be accounted for in calculating frequencies. This volume examines statistical issues in interpreting frequencies as probabilities, including adjustments when a suspect is found through a database search. The committee includes a detailed discussion of what its recommendations would mean in the courtroom, with numerous case citations. By resolving several remaining issues in the evaluation of this increasingly important area of forensic evidence, this technical update will be important to forensic scientists and population geneticistsâ€"and helpful to attorneys, judges, and others who need to understand DNA and the law. Anyone working in laboratories and in the courts or anyone studying this issue should own this book.

Public managers, contractors, and grantees conducting evaluations for government operate in a complex environment where policymakers and commissioners of evaluation expect different types of "evidence" and simultaneously employ different criteria in judging the quality of that evidence. Evidence-Building and Evaluation in Government provides a road map for evaluators doing business within or for government, and public managers who are expected to assess and use evidence generated by a large variety of evaluation approaches. The book provides checklists and how-to guidance to help students and other readers develop skills in important activities such as: assessing the quality of evidence claims; developing theories of change to guide the design and evaluation of programs and policies; developing learning agendas to bridge the gap between evidence producers and potential evidence users; and increasing the support of public leaders and executives in the generation and use of evidence to inform their decision-making. Authors Kathryn Newcomer and Nicholas Hart include end-of-chapter exercises for readers to test their ability to apply the skills described.
