With increased emphasis on helping readers understand the context in which power calculations are done, this Second Edition of How Many Subjects? by Helena Chmura Kraemer and Christine Blasey introduces a simple technique of statistical power analysis that allows researchers to compute approximate sample sizes and power for a wide range of research designs. Because the same technique is used with only slight modifications for different statistical tests, researchers can then easily compare the sample sizes required by different designs and tests to make cost-effective decisions in planning a study. These comparisons demonstrate important principles of design, measurement, and analysis that are rarely discussed in courses or textbooks, making this book a valuable instructional resource as well as a must-have guide for frequent reference.

ICIARisorganizedannually,andalternatesbetweenEuropeandNorthAmerica. ICIAR 2004 was held in Porto, Portugal and ICIAR 2005 in Toronto, Canada. The idea of o?ering these conferences came as a result of discussion between researchers in Portugal and Canada to encourage collaboration and exchange, mainlybetweenthesetwocountries,butalsowiththeopenparticipationofother countries, addressing recent advances in theory, methodology and applications. The response to the call for papers for ICIAR 2006 was higher than the two previous editions. From 389 full papers submitted, 163 were ?nally accepted (71 oral presentations, and 92 posters). The review process was carried out by the Program Committee members and other reviewers; all are experts in various image analysis and recognition areas. Each paper was reviewed by at least two reviewers, and also checked by the conference Co-chairs. The high quality of the papers in these proceedings is attributed ?rst to the authors, and second to the quality of the reviews provided by the experts. We would like to thank the authors for responding to our call, and we wholeheartedly thank the reviewers for their excellent work and for their timely response. It is this collective e?ort that resulted in the strong conference program and high-quality proceedings in your hands.

Basic Electrophysiological Methods provides a concise and easy-to-read guide on a selection of the most important contemporary electrophysiological techniques, their implementation, applications, and ways in which they can be combined and integrated with neuroscientific techniques. Intended for students, postdocs, and faculty with a basic neuroscience background, this text will not obscure the relevant technical details with textbook neuroscience tutorials as many other books do. Instead, each chapter provides a conscientious overview of the underlying theory -- a comprehensive description of equipment, materials, methods, data management, and analysis -- a troubleshooting guide, and a list of frequently asked questions. No book or online resource can function as strictly a DIY set of instructions on how to implement a complex technique. However, this book provides a fundamental and accessible set of information intended to form a foundation prior to, during, and after hands-on experience and training, greatly facilitating the initial learning process and subsequent fine-tuning of technical details.

When social psychologist Stanley Milgram invited volunteers to take part in an experiment at Yale in the summer of 1961, none of the participants could have foreseen the worldwide sensation that the published results would cause. Milgram reported that fully 65 percent of the volunteers had repeatedly administered electric shocks of increasing strength to a man they believed to be in severe pain, even suffering a life-threatening heart condition, simply because an authority figure had told them to do so. Such behavior was linked to atrocities committed by ordinary people under the Nazi regime and immediately gripped the public imagination. The experiments remain a source of controversy and fascination more than fifty years later. In Behind the Shock Machine, psychologist and author Gina Perry unearths for the first time the full story of this controversial experiment and its startling repercussions. Interviewing the original participants—many of whom remain haunted to this day about what they did—and delving deep into Milgram’s personal archive, she pieces together a more complex picture and much more troubling picture of these experiments than was originally presented by Milgram. Uncovering the details of the experiments leads her to question the validity of that 65 percent statistic and the claims that it revealed something essential about human nature. Fleshed out with dramatic transcripts of the tests themselves, the book puts a human face on the unwitting people who faced the moral test of the shock machine and offers a gripping, unforgettable tale of one man’s ambition and an experiment that defined a generation.

Like the River Ganges flowing down from the Himalayas, the entire Buddhist tradition flows down to us from the teachings and deeds of the historical Buddha, who lived and taught in India during the fifth century B.C.E. To ensure that his legacy would survive the ravages of time, his direct disciples compiled records of the Buddha's teachings soon after his passing. In the Theravada Buddhist tradition, which prevails in Sri Lanka and Southeast Asia, these records are regarded as the definitive "word of the Buddha." Preserved in Pali, an ancient Indian language closely related to the language that the Buddha spoke, this full compilation of texts is known as the Pali Canon. At the heart of the Buddha's teaching were the suttas (Sanskrit sutras), his discourses and dialogues. If we want to find out what the Buddha himself actually said, these are the most ancient sources available to us. The suttas were compiled into collections called "Nikayas," of which there are four, each organized according to a different principle. The Digha Nikaya consists of longer discourses; the Majjhima Nikaya of middle-length discourses; the Samyutta Nikaya of thematically connected discourses; and the Anguttara Nikaya of numerically patterned discourses. The present volume, which continues Wisdom's famous Teachings of the Buddha series, contains a full translation of the Anguttara Nikaya. The Anguttara arranges the Buddha's discourses in accordance with a numerical scheme intended to promote retention and easy comprehension. In an age when writing was still in its infancy, this proved to be the most effective way to ensure that the disciples could grasp and replicate the structure of a teaching.

This self-contained account of the statistical basis of epidemiology has been written specifically for those with a basic training in biology, therefore no previous knowledge is assumed and the mathematics is deliberately kept at a manageable level. The authors show how all statistical analysis of data is based on probability models, and once one understands the model, analysis follows easily. In showing how to use models in epidemiology the authors have chosen to emphasize the role of likelihood, an approach to statistics which is both simple and intuitively satisfying. More complex problems can then be tackled by natural extensions of the simple methods. Based on a highly successful course, this book explains the essential statistics for all epidemiologists.
