This paper considers how parents engage with a large, internationally supported childhood pneumococcal vaccine trial in The Gambia. Current analysis and professional reflection on public engagement is strongly shaped by the imperatives of public health and research institutions, and is thus couched in terms of acceptance and refusal, and . In contrast Gambian parents in the extreme, of free medical treatment, versus onepublic engagement with science’ in a globalized context might be recast, with implications for debates in biomedical ethics, and (...) the sustainability of public participation in medical research.

Central African highland farmers' perceptions of common bean disease were investigated using both phytopathology and anthropological techniques. Farmers rarely mentioned diseases as production constraints in formal questionnaires. More participatory research showed farmers often related disease symptoms to the effects of rain and soil depletion for fungal diseases, or to varietal traits for bean common mosaic virus. Rain or moisture is divided into numerous forms through which it can damage plants, both physically and through putrefaction. Most conditions associated with putrefaction appear (...) to be linked to pathogens. Farmers have an understanding of plant health closely related to their concept of human health. In plants, this understanding is based on the prior state of plant health. Conceptually, local disease management strategies are based on prevention by managing the conditions that promote good plant health rather than by treating disease symptoms. Intervention strategies that build on local knowledge are encouraged. (shrink)
