Conventions are regularities in social behaviour of the past that enable us to coordinate our actions. Some conventions are lawlike: they are expected to be observed always or nearly always. However, in order to coordinate our actions, it may suffice that a precedent has occurred often enough, and sometimes even a single precedent will do. So, in general, conventions merely enable us to solve our coordination problems; lawlike conventions are a special case. Grammatical conventions are often lawlike; sense conventions are (...) typically enabling. In order to resolve the indeterminacies that sense conventions give rise to, interlocutors must rely on the common ground. In this and other ways, common ground is a prerequisite for convention‐based communication. (shrink)

A common and driving assumption in agricultural research is that the introduction of research trials, new practices and innovative technologies will result in technology adoption, and will subsequently generate benefits for farmers and other stakeholders. In Lao PDR, the potential benefits of introduced technologies have not been fully realised by beneficiaries. We report on an analysis of a survey of 735 smallholder farmers in Southern Lao PDR who were questioned about factors that influenced their decisions to adopt new technologies. In (...) this study, we have constructed measures or states of adoption which identify key elements of an adoption decision-making nexus. Analysis was conducted to statistically group explanatory factors of adoption. The key explanatory factors represented attributes of the farmer, the factors considered when undertaking production decisions and elements of the agricultural value chain that present as opportunities or constraints. We describe the combination of farmer’s personal attributes, perceptions of the value chain, and the introduction of new technologies by external actors as an “agricultural research value chain”, where agricultural research activities intervene to derive greater benefits for local farmers. A generalised linear model, via Poisson regression analysis on the identified explanatory factors, was applied to explore how they influence adoption measures and we found several significant relationships.
