Indigenous Midwifery Apprenticeship Knowledge Transmission and Neonatal Care Competence in Malawian Yao Villages: A Social-Network Estimation of Skill Diffusion and Attrition
Description
The model treats neonatal care competence as a dyadic transmission process in which knowledge flows from master midwives to apprentices along village kinship and apprenticeship ties, with attrition modelled as tie dissolution. Because no observational data are available, the paper reports a replication-based power analysis under a declared variance structure (between-cluster SD = 6.0, residual SD = 4.5, intraclass correlation = 0.64). Across 2000 replications per design cell, the analysis evaluates cluster counts of 8, 16, 24 and 32 and effect sizes of 3, 5 and 8 percentage points. The results indicate that 52 clusters are required to detect a 5-percentage-point effect at 80% power, and that the BACI interaction estimator is sensitive to the intraclass correlation in ways that have direct consequences for the design of evaluations of indigenous knowledge transmission.
