The rapid increase in primary enrollment seen in many developing countries might further worsen the poor schooling quality often found in these countries. I estimate the effect of enrollment growth following the removal of primary school fees in Tanzania and find that it led to sizeable increases in the pupil-teacher ratio and a reduction in observable teacher quality, but rule out a substantia...

One major limitation to addressing child undernutrition is a lack of the information required to target resources. This article extends the small-area estimation technique of Elbers, Lanjouw, and Lanjouw (2002, 2003) to jointly estimate multiple equations while allowing for individual-specific random errors across equations (in addition to clusterand household-specific random errors). Estimates...

Traditional enteropathogenic Escherichia coli serotypes demonstrate a plasmid-mediated localized adherence in cultured HeLa or HEp-2 cells and induce an attaching-effacing intestinal lesion, both of which are considered pathognomonic and causes of diarrhea. This study describes three E. coli strains from infantile diarrhea which share these properties but belong to serotypes (O2:H2, O2:H25 and ...

Forage brassicas are used as a forage in monoculture and multispecies mixtures, yet research defining best management practices is limited. Two studies were conducted to evaluate the effects of land preparation method planting date on establishment, mass, quality two Brassica species, ‘Inspiration’ canola (Brassica napus L.) ‘T-Raptor’ hybrid turnip (B. rapa subsp. × B. L.). Each experiment was...
