Educational policy-makers around the world constantly make decisions about how to use scarce resources to improve the education of children. Unfortunately, their decisions are rarely informed by evidence on the consequences of these initiatives in other settings. Nor are decisions typically accompanied by well-formulated plans to evaluate their causal impacts. As a result, knowledge about what works in different situations has been very slow to accumulate. Over the last several decades, advances in research methodology, administrative record keeping, and statistical software have dramatically increased the potential for researchers to conduct compelling evaluations of the causal impacts of e...
By charting changes over time and investigating whether and when events occur, researchers reveal the temporal rhythms of our lives.
Will America find enough good teachers to staff its public schools? How can we ensure that all our children will be taught by skilled professionals? The policies that determine who teaches today are a confusing and often conflicting array that includes tougher licensing requirements, higher salaries, mandatory master's degrees, merit pay, and alternative routes to certification. Who Will Teach? examines these policies and separates those that work from those that backfire. The authors present an intriguing portrait of America's teachers and reveal who they are, who they have been, and who they will be. Using innovative statistical methods to track the professional lives of more than 50,000 c...
Do students who work longer and harder learn more in college? Does joining a fraternity with a more academic flavor enhance a student's academic performance? These are just some more than fifty examples that Richard Light Judith Singer and John Willett explore in By Design, a lively nontechnical sourcebook for learning about colleges and universities.
In this national bestseller based on Harvard Medical School and Harvard School of Public Health research, Dr. Willett explains why the USDA guidelines--the famous food pyramid--are not only wrong but also dangerous.
How can a scientist or policy analyst summarize and evaluate what is already known about a particular topic? This book offers practical guidance. The amount and diversity of information generated by academic and policy researchers in the contemporary world is staggering. How is an investigator to cope with the tens or even hundreds of studies on a particular problem? How can conflicting findings be reconciled? Richard Light and David Pillemer have developed both general guidelines and step-by-step procedures that can be used to synthesize existing data. They show how to apply quantitative methods, including the newest statistical procedures and simple graphical displays, to evaluate a mass o...
"Born in Berlin in 1891, John Heartfield grew up in Germany during the formative years of the main modern movements: Expressionism, Cubism, Futurism, each of which contributed recognisably to the photomontages for which he would become famous. Sharply critical of the Weimar Republic in which he flourished, in Germany his work was banned for the duration of Hitler's Third Reich. In London, where he lived as an anti-Fascist exile throughout the Second World War, he remained an outsider till after his return to East Germany in 1950, It is only since the 1970s that he has become a European, if not a world figure."--Cover

Offers a biography of the nineteenth century poet, offering insights into the details of his early life in London, the torments that affected him, and the imaginative sources of his works.
The last two decades have seen enormous developments in statistical methods for incomplete data. The EM algorithm and its extensions, multiple imputation, and Markov Chain Monte Carlo provide a set of flexible and reliable tools from inference in large classes of missing-data problems. Yet, in practical terms, those developments have had surprisingly little impact on the way most data analysts handle missing values on a routine basis. Analysis of Incomplete Multivariate Data helps bridge the gap between theory and practice, making these missing-data tools accessible to a broad audience. It presents a unified, Bayesian approach to the analysis of incomplete multivariate data, covering dataset...
