Evaluation of Diagnostic Systems: Methods from Signal Detection Theory addresses the many issues that arise in evaluating the performance of a diagnostic system, across the wide range of settings in which such systems are used. These settings include clinical medicine, industrial quality control, environmental monitoring and investigation, machine and metals inspection, military monitoring, information retrieval, and crime investigation. The book is divided into three parts encompassing 11 chapters that emphasize the interpretation of diagnostic visual images by human observers. The first part of the book describes quantitative methods for measuring the accuracy of a system and the statistical techniques for drawing inferences from performance tests. The subsequent part covers study design and includes a detailed description of the form and conduct of an image-interpretation test. The concluding part examines the case study of a medical imaging system that serves as an example of both simple and complex applications. In this part, three mammographic modalities are used: industrial film radiography, low-dose film radiography, and xeroradiography. The case study focuses on the overall reliability of accuracy indices made by its main components, that is, the variabilities across cases, across readers, and within individual readers. The supplementary texts provide study protocols, a computer program for processing test results, and an extensive list of references that will assist the reader in applying those evaluative methods to diagnostic systems in any setting. This book is of value to scientists and engineers, as well as to applied, quantitative, or experimental psychologists who are engaged in the study of the human processes of discrimination and decision making in either perceptual or cognitive tasks.

Fundamentals of Evaluation and Diagnostics of Welded Structures provides an essential guide to the key principles and problems involved in the analysis of welded structures. Chapter one discusses design issues, key equations and calculations, and the effects of varied heat sources in relation to the temperature field in welding. Chapter two goes on to explore welding stresses and strains. Fracture mechanics and the load-carrying capacity of welded structures are the focus of chapter three. Chapter four considers diagnostics and prediction of the residual life of welded structures, whilst acoustic emission techniques for the analysis of welded structures are reviewed in chapter five. Finally, chapter six supplies supplementary information on numerical techniques and other tests for welded structures. With its distinguished author and detailed coverage, Fundamentals of evaluation and diagnostics of welded structures is an indispensable guide for welding and structural engineers as well as those researching this important topic.

Statistical evaluation of diagnostic performance in general and Receiver Operating Characteristic (ROC) analysis in particular are important for assessing the performance of medical tests and statistical classifiers, as well as for evaluating predictive models or algorithms. This book presents innovative approaches in ROC analysis, which are relevant to a wide variety of applications, including medical imaging, cancer research, epidemiology, and bioinformatics. Statistical Evaluation of Diagnostic Performance: Topics in ROC Analysis covers areas including monotone-transformation techniques in parametric ROC analysis, ROC methods for combined and pooled biomarkers, Bayesian hierarchical transformation models, sequential designs and inferences in the ROC setting, predictive modeling, multireader ROC analysis, and free-response ROC (FROC) methodology. The book is suitable for graduate-level students and researchers in statistics, biostatistics, epidemiology, public health, biomedical engineering, radiology, medical imaging, biomedical informatics, and other closely related fields. Additionally, clinical researchers and practicing statisticians in academia, industry, and government could benefit from the presentation of such important and yet frequently overlooked topics.

This book is a collection of papers, exploring how designers, researchers and practitioners respond to the changing nature of contemporary perceptions of the relationship between humans and technology. Originating from a workshop at the 2012 Design Research Society Conference in Bangkok, the book presents diverse approaches from theoretical explorations to practical methods and educational solutions. The papers are presented in three sections with the first providing background information to the workshop and the perceptions of the relationship between humans and technology. Section two explores the theme of emotions and technology, investigating emotional responses to design solutions, methods for tracing facial and body expressions and the creation of the Kansei Design Education programmes. The final section is titled ‘Design and Technology’ and provides perspectives on how everyday and educational environments transform in response to the changing nature of the relationship between humans and technology. The book does not aim to provide a unified voice on how design practices change in response to new technologies, but it provides a platform for diverse cross-disciplinary debates on how designers and design educators respond to the changes in our contemporary understanding of the humans/technology relationship.

Advances in the standardization, precision and thoroughness of psychiatric diagnosis are being supplemented with attention to personalized or ideographic descriptive approaches. This promises not only to enhance the clinician's understanding of a case but to allow a fuller and more effective use of the evolving range of therapeutic possibilities. To reflect these developments, the Section on Classification, Diagnostic Assessment and Nomenclature of the World Psychiatric Association has prepared this volume which is organized around five prominent themes in contemporary psychiatric diagnosis: -major regional perspectives - ICD-10 - comprehensive diagnosis through the multiaxial model - treatment planning and organization of health services - the role and challenges of psychiatric diagnosis in primary health care.
