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.

A complete guide to understanding cluster randomised trials Written by two researchers with extensive experience in the field, this book presents a complete guide to the design, analysis and reporting of cluster randomised trials. It spans a wide range of applications: trials in developing countries, trials in primary care, trials in the health services. A key feature is the use of R code and code from other popular packages to plan and analyse cluster trials, using data from actual trials. The book contains clear technical descriptions of the models used, and considers in detail the ethics involved in such trials and the problems in planning them. For readers and students who do not intend to run a trial but wish to be a critical reader of the literature, there are sections on the CONSORT statement, and exercises in reading published trials. Written in a clear, accessible style Features real examples taken from the authors’ extensive practitioner experience of designing and analysing clinical trials Demonstrates the use of R, Stata and SPSS for statistical analysis Includes computer code so the reader can replicate all the analyses Discusses neglected areas such as ethics and practical issues in running cluster randomised trials How to Design, Analyse and Report Cluster Randomised Trials in Medicine and Health Related Research provides an excellent reference tool and can be read with profit by statisticians, health services researchers, systematic reviewers and critical readers of cluster randomised trials.

ICIAR 2006, the International Conference on Image Analysis and Recognition, was the third ICIAR conference, and was held in P ́ ovoa de Varzim, Portugal. 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.

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.
