Gender differences in knowledge of NRM practices have long been noted in Senegal and throughout Sub-Saharan Africa. An exploration of these differences among a sample of rural Senegalese men and women shows that these differences are, in part, a function of extension agent interventions. The level of knowledge of a set of NRM technologies is associated with contact with three key types of extension agent in rural Senegal: extension team leaders, forestry agents, and women's agents. Analysis of intra-household variation in (...) levels of knowledge shows a degree of interdependence between the knowledge levels of husbands and wives for some practices. However, multi-variate analysis, controlling for personal and contextual factors, clearly demonstrates the independent impact of extension agents on gender differences in rural Senegalese NRM knowledge. It can be concluded that contact with extension agents increases knowledge of NRM practices. In particular, contact with the women's agent is a strong predictor of the level of women's NRM knowledge and, surprisingly, also contributes to the level of men's knowledge. Despite the small number of women's agents in the field, they appear to have significant positive impact on the dissemination of NRM knowledge among rural Senegalese women and men. (shrink)

BackgroundLittle is known about volunteers from Northern research settings who participate in vaccine trials of highly infectious diseases with no approved treatments. This article explores the motivations of HIV immunocompromised study participants in Canada who volunteered in a Phase II clinical trial that evaluated the safety and immunogenicity of an Ebola vaccine candidate.MethodsObservation at the clinical study site and semi-structured interviews employing situational and discursive analysis were conducted with clinical trial participants and staff over one year. Interviews were recorded, transcribed (...) and analysed using critical qualitative interpretivist thematic analytical techniques. Patterns were identified, clustered and sorted to generate distinct and comprehensive themes. We then reassembled events and contexts from the study participants’ stories to develop two ideal portraits based on "composite characters" based on study participants features. These provide ethnographically rich details of participants’ meaningful social worlds while protecting individual identities.ResultsTen of the 14 clinical trial participants, and 3 study staff were interviewed. Participant demographics and socio-economic profiles expressed limited contextual diversity. Half were men who have sex with men, half were former injection drug users experiencing homelessness, one was female, none were racialized minorities and there were no people from HIV endemic countries. Fully 90% had previous involvement in other clinical studies. Their stories point to particular socio-economic situations that motivated their participation as clinical labor through trial participation.ConclusionsOur findings support Fisher’s argument of “structural coercion” in clinical trial recruitment of vulnerable individuals experiencing precarious living conditions. Clinical trials should provide more detail of the structural socio-economic conditions and healthcare needs which lie “under consent” of study participants. Going well beyond an overly convenient narrative of altruism, ethical deliberation frameworks need to sufficiently address the structural conditions of clinical trials. We offer concrete possibilities for this and acknowledge that further research and clinical data should be made available underlying study participant contexts with regards to recruitment and participation in resource poor settings, in both the South and the North.
