Social networks play a significant role in learning and thus in farmers’ adoption of new agricultural technologies. This study examined the effects of social network factors on information acquisition and adoption of new seed varieties among groundnut farmers in Uganda and Kenya. The data were generated through face-to-face interviews from a random sample of 461 farmers, 232 in Uganda and 229 in Kenya. To assess these effects two alternative econometric models were used: a seemingly unrelated bivariate probit model and a (...) recursive bivariate probit model. The statistical evaluation of the SUBP shows that information acquisition and adoption decisions are interrelated while tests for the RBP do not support this latter model. Therefore, the analysis is based on the results obtained from the SUBP. These results reveal that social network factors, particularly weak ties with external support, partially influence information acquisition, but do not influence adoption. In Uganda, external support, gender, farm size, and geographic location have an impact on information acquisition. In Kenya, external support and geographic location also have an impact on information acquisition. With regard to adoption, gender, household size, and geographic location play the most important roles for Ugandan farmers, while in Kenya information from external sources, education, and farm size affect adoption choice. The study provides insight on the importance of external weak ties in groundnut farming, and a need to understand regional differences along gender lines while developing agricultural strategies. This study further illustrates the importance of farmer participation in applied technology research and the impact of social interactions among farmers and external agents. (shrink)

Researchers, scientists, and physicians in Uganda have become increasingly aware of the need to develop a systematic approach to reviewing bio-medical research conducted in their country. Much of this awareness and their concern stems from Uganda's high seroprevalence of human immunodeficiency virus and the consequent large influx of research monies and HIV researchers from developed countries, including the United States and Great Britain.We report on the proceedings of a five-day symposium on bioethical principles governing clinical trials, which convened in Jinja, (...) Uganda in September 1994. The thirteen male and female workshop participants included representatives from the Uganda Ministry of Health, Makerere University, the Uganda AIDS Commission, Uganda's National Council of Science and Technology, and the National Chemotherapeutic Laboratory. These representatives included ethicists, physicians, researchers, and pharmacists, all of whom have conducted research themselves. Initial workshop sessions focused on the history of human experimentation and the development of protections for human participants in medical research, both in the United States and internationally.

In July 1997, the voting representatives at the National Consensus Conference on Bioethics in Health Research voted unanimously to adopt the proposed Guidelines for the Conduct of Health Research Involving Human Subjects in Uganda. This vote represented the culmination of a three-year journey towards the development of a coherent and cohesive framework for the ethical review of health research involving human subjects in Uganda.Attendees at the NCC included both voting representatives and non-voting participants. Voting representatives had been designated by the (...) institutional entity with which they were affiliated to represent that entity at the NCC and to voice the concerns and opinions of the entity and its constituents.
