U.S. Secretary of Energy nominee Rick Perry testifies at his confirmation hearing in this excerpt
No full textEnergy Secretary nominee and former Texas Governor Rick Perry, testifies before the Senate Energy and Natural Resources Committee in this excerpt from his confirmation hearing. Senator Lisa Murkowski (R-AK) chairs the hearing and makes opening statements. Senators John Cornyn (R-TX) and Joe Manchin (D-WV) introduce Perry. Following his introductory remarks, Perry answers questions about comments he made during his presidential bid about ending the EPA and denying global warming. Perry also talks about nuclear waste disposal. Senator Debbie Stabenow (D-MI) asks Perry about funding for the Facility for Rare Isotope Beams (F-RIB) at Michigan State University
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
