Analyzing Social Experiments as Implemented: A Reexamination of the Evidence from the HighScope Perry Preschool Program
No full textSocial experiments are powerful sources of information about the effectiveness of interventions. In practice, initial randomization plans are almost always compromised. Multiple hypotheses are frequently tested. "Significant" effects are often reported with p-values that do not account for preliminary screening from a large candidate pool of possible effects. This paper develops tools for analyzing data from experiments as they are actually implemented. We apply these tools to analyze the influential HighScope Perry Preschool Program. The Perry program was a social experiment that provided preschool education and home visits to disadvantaged children during their preschool years. It was evaluated by the method of random assignment. Both treatments and controls have been followed from age 3 through age 40. Previous analyses of the Perry data assume that the planned randomization protocol was implemented. In fact, as in many social experiments, the intended randomization protocol was compromised. Accounting for compromised randomization, multiple-hypothesis testing, and small sample sizes, we find statistically significant and economically important program effects for both males and females. We also examine the representativeness of the Perry study.social experiment, compromised randomization, early childhood intervention, multiple-hypothesis testing

Variations on the Author
No full text“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
University of Washington, Department of History memo regarding Professor Perry Miller's turning down an invitation to lecture at the university, March 7, 1955
No full textIn this two part document the Department of History writes a memo on Professor of American Literature Perry Miller and his decision not be a guest lecturer at the University of Washington in April of 1955. Professor Perry Miller writes to the History Department “I was profoundly distressed by the reaction action of President Henry Schmitz in barring Dr. J. Robert Oppenheimer from lecturing before the Physics Department.” Miller continues with stating “This action seems to me not only an egregious insult to a great scholar but also a flagrant violation of the fundamental principles of intellectual integrity and liberty of spirit upon which the education system of a free society is erected.”Professor Perry Miller earned all his degrees (BA, MA, PhD) from the University of Chicago after which he began teaching at Harvard University in 1931. Miller served in the US Army during World War II and resumed teaching at Harvard in 1945. He is best known for his work on American Puritanism, and his founding role in the field of American Studies, Miller won a Pulitzer Prize (posthumously) for his work The Life of the Mind in America. He passed in 1963

The UMBC Applied Sociology MA Program
No full textThis episode features the remarkable UMBC MA in Applied Sociology program. Contact the program for more information at [email protected].
First we hear from Dr. Christine Armstrong Mair and Dr. Brandy H. Wallace, both UMBC faculty members affiliated with the Applied Sociology program. We also hear from two current MA students working on theses in applied sociology, R.B. Brauer and Jayla Gray-Thomas, and two recent alumni of the program, Fariha Khalid and Perry Gilchrist.
