SUMMARYGroundnut (Arachis hypogaea) has very great economic importance in Cameroon. In pot experiments, groundnut yields on highly acidified but limed soil were 50% greater than those on unlimed soil. These results demonstrate that severely acidified soils of the western highlands of Cameroon should be limed at moderate rates to sustain crop productivity.

After the dissolution of the first national airline in 2002, the Guinean government attempted to set up Guinea Airlines, but it was unsuccessful. This study aims to analyze the current state of air transport in Guinea and to conduct a diagnostic analysis for the revival of the national airline. The objective is to explore the causes of the failures of various attempts to revive the national company. The findings show that air transport has a positive spillover externality to economic long-run growth and the revival of Guinea Airlines could be a major asset to boost the country’s economic growth.

The proliferation of transnational institutions in the form of protocols, conventions, regimes and standards is a growing influence on organizational practice. Recent work on the origins and impact of transnational institutions focuses upon processes in ‘core’ states, but their influence in developing countries has not received much attention. In this paper we narrate a case study of the diffusion of two institutional regimes represented by the International Civil Aviation Organization (ICAO) and the International Air Transport Association (IATA) in Iranian civil aviation. The case study describes a seemingly frictionless and uncontested embedding of the emergent international aviation regime in post-World War II Iran and a severe challenge to those institutions in the years following Iran's Islamic revolution. We characterize the rise and decline of these regimes as a double process of institutionalization and de-institutionalization, and identify political and technical factors that drive institutional change. We discuss several theoretical and policy implications stemming from the experience of transnational aviation institutions in Iran.
