Analyzing social experiments as implemented: evidence from the HighScope Perry Preschool Program
Social 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. Download appendix

Analyzing Social Experiments as Implemented: A Reexamination of the Evidence From the HighScope Perry Preschool Program
Social 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. "Signicant" effects are often reported with p-values that do not account for preliminary screening from a large candidate pool of possible effects.

Validation of the Thomson, Perry and Miller collaboration instrument
Abstract: South African organisations face unique challenges that require optimal use of resources to improve business results. Effective collaboration is considered a powerful strategy to achieve this. Measuring the extent of collaboration can help to identify required changes in business practices. As far as could be established, there is no evidence of collaboration instruments developed and validated in South Africa. Thomson, Perry, & Miller (2007) developed a collaboration measurement instrument in the USA. The aim of this study was to validate this instrument for a South African context. Additional items were designed for further development of the sub-scales, as suggested by Thomson et al. (2007). The revised questionnaire consisting of 31 items (17 original and 14 new) was distributed electronically to 4200 employees in two organisations, with 343 valid responses received. Reliability and construct validity was tested as was convergent validity of the norms factor with the Trust in Teams Scale. The results of the study support a four-factor, 29 item model of collaboration when applied to a South African sample. Cronbach Alphas of the four factors are: Factor 1: Governance (α = .95), Factor 2: Mutuality (α = .92), Factor 3: Norms (α = .90), Factor 4: Autonomy (α = .85). CFA fits were at an acceptable level: RMSEA = 0.099 within the 90% confidence interval of 0.093 and 0.104. CFI’s are between .86 and .99. Convergent validity of the Trust in Teams scale with the norms factor of the Thomson, Perry and Miller (2007) Collaboration Instrument shows a moderate fit with the data: CFI = 0.85, RMSEA = 0.15 within the 90% confidence interval of 0.14 and 0.15. An understanding of the conditions related to effective collaboration and measurement thereof could equip managers and Human Resources practitioners to address collaboration opportunities and obstacles. This study provides a valid measure of collaboration in two South African industries.M.Phil
Saving Rutgers Camden
In January 2012, Chris Christie, Governor of New Jersey, announced that the Camden campus of Rutgers, the State University, was to be severed from Rutgers and taken over by Rowan University. Every major political force in the state, Democratic and Republican, elected and behind the scenes, lined up in support of the plan. Nevertheless, Rutgers-Camden faculty, students, administrators, alumni, and trustees, and their allies, vigorously fought the plan, convinced that it made no sense and would be devastating to the campus and higher education in the State more generally. The campaign opposing the merger with Rowan was popular and political, but it ultimately depended on powerful legal arguments grounded in Rutgers’ distinct and complex history. By the end of June, the merger idea had been defeated. As one assistant professor put it, “The bad guys got outmaneuvered by a bunch of nerds.”
This article is a scholarly effort by three faculty participants to make sense of the struggle to save Rutgers-Camden and put it in theoretical context. The article narrates the story of the fight over the proposed merger and carefully analyzes the legal constraints on the plan. It also links the story to important broader questions about legal pluralism, the public/private divide, the relationship between state universities and state governments, and competing visions of the modern university faculty. Through this combination of case study, legal argument, and conceptual inquiry, the article provides a cautionary but hopeful tale about the importance of academic communities defending sound public policy and their own historical rights to self determination against the machinations that can infect our political culture and legislative process.Please direct any questions about this deposit to Charlotte Schneider ([email protected])
Essor et déclin des télégraphes britanniques en tant que service public
THE RISE AND FALL OF GOVERNMENT TELEGRAPHY IN BRITAIN Charles R. Perry The first nationalization in England was that of the telegraph. This phenomenon, overlooked for many years by historians, is considered here by the author who analyses the government's arguments in the 1860s. He then reviews a complex and contrasting heritage (the rise and fall): social achievement but financial failure.ESSOR ET DECLIN DES TELEGRAPHES BRITANNIQUES EN TANT QUE SERVICE PUBLIC Charles R. Perry La nationalisation du télégraphe fut la première à intervenir en Angleterre. Ce phénomène, longtemps ignoré des historiens, est repris ici par l'auteur qui analyse d'abord ce que fut dans les années 1 860 l'argument des pouvoirs publics. Il s'attache ensuite au bilan (l'essor et le déclin) d'un héritage complexe et contrasté : une réussite sociale, mais un échec fiscal.Perry Charles R., Albaret Michèle.
