Learning from second-hand experience: methodology for extrapolation-oriented case research

Critics of public management reform complain that governments copy legitimated foreign practices. Recent work by Eugene Bardach helps to explain why: neither government analysts nor academic researchers possess an adequate methodology to examine practices in source sites, with a view toward adaptation in target sites. Rather than complain, Bardach takes steps to develop such a methodology, drawing analogies with reverse engineering. This article offers specific guidance about how researchers can effectively investigate practices in source sites to prepare the ground for disciplined and ingenious extrapolation of practices from source to target sites. The resulting translation is illustrated by an extrapolation-oriented case study

Cortisol awakening response and developmental outcomes at 6–7 years in children born extremely preterm

BackgroundExtremely preterm (EPT) birth has been related to dysregulation of stress responses and behavioral/learning problems at school age. Early adverse experiences can blunt HPA axis reactivity. We hypothesized that an attenuated cortisol awakening response would be associated with developmental and behavioral problems at school age in EPT children.MethodsThis secondary analysis of a sub-cohort of the SUPPORT study included children born between 24 and 27 weeks, evaluated at 6-7 years with a neurodevelopmental battery and cortisol measures. Differences were tested between EPT and a term-born group. Relationships of cortisol awakening response to test scores were analyzed.ResultsCortisol was measured in 110 EPT and 29 term-born 6-7 year olds. Unadjusted WISC-IV and NEPSY-II scores were significantly worse among EPT children only. Conners Parent Rating Scale behavior scores were significantly worse among EPT children. After adjusting for covariates, blunted cortisol awakening responses were found to be associated with poorer scores on memory tests and greater problems with inattention for the EPT group (p < 0.05) only.ConclusionsAmong children born EPT, we identified an association of blunted cortisol awakening response with memory and inattention problems. This may have implications related to stress reactivity and its relationship to learning problems in children born EPT.ClinicaltrialsGov idExtended Follow-up at School Age for the SUPPORT Neuroimaging and Neurodevelopmental Outcomes (NEURO) Cohort: NCT00233324.ImpactIn children born EPT, stress reactivity may have a relationship to learning problems. Cortisol awakening response should be a component for follow-up in EPT born children. Components of executive function, such as memory and attention, are related to stress reactivity
