Dispelling the common notion that American women became activists in the fight against female cancer only after the 1970s, Kirsten E. Gardner traces women's cancer education campaigns back to the early twentieth century. Focusing on breast cancer, but using research on cervical, ovarian, and uterine cancers as well, Gardner's examination of films, publications, health fairs, and archival materials shows that women have promoted early cancer detection since the inception of the American Society for the Control of Cancer in 1913. While informing female audiences about cancer risks, these early activists also laid the groundwork for the political advocacy and patient empowerment movements of recent decades. By the 1930s there were 300,000 members of the Women's Field Army working together with women's clubs. They held explicit discussions about the risks, detection, and incidence of cancer and, by mid-century, were offering advice about routine breast self-exams and annual Pap smears. The feminist health movement of the 1970s, Gardner explains, heralded a departure for female involvement in women's health activism. As before, women encouraged early detection, but they simultaneously demanded increased attention to gender and medical research, patient experiences, and causal factors. Our understanding of today's vibrant feminist health movement is enriched by Gardner's work recognizing women's roles in grassroots educational programs throughout the twentieth century and their creation of supportive networks that endure today.
Signal detection theory--as developed in electrical engineering and based on statistical decision theory--was first applied to human sensory discrimination 40 years ago. The theoretical intent was to provide a valid model of the discrimination process; the methodological intent was to provide reliable measures of discrimination acuity in specific sensory tasks. An analytic method of detection theory, called the relative operating characteristic (ROC), can isolate the effect of the placement of the decision criterion, which may be variable and idiosyncratic, so that a pure measure of intrinsic discrimination acuity is obtained. For the past 20 years, ROC analysis has also been used to measure the discrimination acuity or inherent accuracy of a broad range of practical diagnostic systems. It was widely adopted by methodologists in the field of information retrieval, is increasingly used in weather forecasting, and is the generally preferred method in clinical medicine, primarily in radiology. This book attends to both themes, ROC analysis in the psychology laboratory and in practical diagnostic settings, and to their essential unity. The focus of this book is on detection and recognition as fundamental tasks that underlie most complex behaviors. As defined here, they serve to distinguish between two alternative, confusable stimulus categories, which may be perceptual or cognitive categories in the psychology laboratory, or different states of the world in practical diagnostic tasks. This book on signal detection theory in psychology was written by one of the developers of the theory, who co-authored with D.M. Green the classic work published in this area in 1966 (reprinted in 1974 and 1988). This volume reviews the history of the theory in engineering, statistics, and psychology, leading to the separate measurement of the two independent factors in all discrimination tasks, discrimination acuity and decision criterion. It extends the previous book to show how in several areas of psychology--in vigilance and memory--what had been thought to be discrimination effects were, in reality, effects of a changing criterion. The book shows that data plotted in terms of the relative operating characteristic have essentially the same form across the wide range of discrimination tasks in psychology. It develops the implications of this ROC form for measures of discrimination acuity, pointing up the valid ones and identifying several common, but invalid, ones. The area under the binormal ROC is seen to be supported by the data; the popular measures d' and percent correct are not. An appendix describes the best, current programs for fitting ROCs and estimating their parameters, indices, and standard errors. The application of ROC analysis to diagnostic tasks is also described. Diagnostic accuracy in a wide range of tasks can be expressed in terms of the ROC area index. Choosing the appropriate decision criterion for a given diagnostic setting--rather than considering some single criterion to be natural and fixed--has a major impact on the efficacy of a diagnostic process or system. Illustrated here by separate chapters are diagnostic systems in radiology, information retrieval, aptitude testing, survey research, and environments in which imminent dangerous conditions must be detected. Data from weather forecasting, blood testing, and polygraph lie detection are also reported. One of these chapters describes a general approach to enhancing the accuracy of diagnostic systems.
This book offers readers an overview of some of the most recent advances in the field of technology for X-ray medical imaging. Coverage includes both technology and applications in SPECT, PET and CT, with an in-depth review of the research topics from leading specialists in the field. Coverage includes conversion of the X-ray signal into analogue/digital value, as well as a review of CMOS chips for X-ray image sensors. Emphasis is on high-Z materials like CdTe, CZT and GaAs, since they offer the best implementation possibilities for direct conversion X-ray detectors. The discussion includes material challenges, detector operation physics and technology and readout integrated circuits required to detect signals processes by high-Z sensors. Authors contrast these emerging technologies with more established ones based on scintillator materials. This book is an excellent reference for people already working in the field as well as for people wishing to enter it.
Over the past few decades, Salmonella has been one of four key global causes of diarrheal diseases and the major cause of foodborne pathogens that could lead to salmonellosis globally. Thereby, a comprehensive overview of recent trends in Salmonella is of great importance for its accurate detection and precise control under different conditions. This book provides an insightful overview of Salmonella, starting from the mechanism of Salmonella transmission, infection, and antimicrobial resistance. Moreover, it also presents new insights into Salmonella prevention and control strategies such as novel antimicrobial agents and methods. The final section discusses novel Salmonella detection and identification technologies, highlighting ongoing issues, recent advances, and future directions in Salmonella diagnostic approaches and prevention strategies.
Constant false alarm rate detection processes are important in radar signal processing. Such detection strategies are used as an alternative to optimal Neyman-Pearson based decision rules, since they can be implemented as a sliding window process running on a radar range-Doppler map. This book examines the development of such detectors in a modern framework. With a particular focus on high resolution X-band maritime surveillance radar, recent approaches are outlined and examined. Performance is assessed when the detectors are run in real X-band radar clutter. The book introduces relevant mathematical tools to allow the reader to understand the development, and follow its implementation.
Still widely used as gene markers, isozymes detected by zymogram techniques have proven valuable in a range of other biological applications over the last few years. Along with these new applications, many new techniques have also emerged. Yet more than eight years since the Handbook of Detection of Enzymes on Electrophoretic Gels was first publish
In the world of law enforcement art and antiquity crime has in the past usually assumed a place of low interest and priority. That situation has now slowly begun to change on both the local and international level as criminals, encouraged in part by the record sums now being paid for art treasures, are now seeking to exploit the art market more systematically by means of theft, fraud and looting. In this collection academics and practitioners from Australasia, Europe and North America combine to examine the challenges presented to the criminal justice system by these developments. Best practice methods of detecting, investigating, prosecuting and preventing such crimes are explored. This book will be of interest and use to academics and practitioners alike in the areas of law, crime and justice.
