Agricultural extension in the Global South can benefit greatly from the use of modern information and communication technologies (ICT). Yet, despite two decades of promising experiences, this potential is not fully realized. Here, we review the relevant research literature to inform future investments into agricultural information services that harness the full potential of digital media. We describe a recently emerging innovation agenda that is, in part, a response to the eventual failure of many new agro-advisory initiatives. One important cause of failure has been a focus on pushing certain technologies, rather than responding to the particular communication challenges of potential users. To avoid such bias in designing new services, the new innovation agenda rests on two major foundations: strong user-centredness and problem-orientation. In our review, we first describe how user-centred design methods help in specifying both problems and (digital) solutions in agricultural extension. To inform responses to the communication challenges defined by that analysis, we then describe eight emerging aspects of using ICT for development, and how they can address common deficiencies of agricultural extension. Practical examples from the literature highlight the possibilities and limitations of these innovation directions. Beyond digital design, however, technological innovation requires enabling institutions.
Placebo-induced performance enhancement is a new controversial issue in competitive sports. Coaches have control over the use of placebos, but their practices and attitudes were barely studied to date. In this survey 96 coaches from regional, national and international levels were asked about their practices and attitudes concerning placebo use in sports. Results revealed that 90% of the respondents were aware of placebo effects. Many (44%) coaches admitted to administering a placebo to their athletes. Those working at international level have administered placebos more often than the others (P = .02). Two thirds of the coaches agreed to the wider use of placebos in sport. Respondents who have used placebos in the past reported improved athletic performance. They also agreed more to the wider use of placebos than the coaches who previously did not use a placebo (P = .001). Team sport coaches use more often placebos than coaches working with individual athletes (P = .05). Only 10% of the sample thought that their athletes would refuse a hypothetical performance enhancer supplied by them. After a successful placebo intervention, only 15% of the coaches would administer it again without consulting the athlete. Overall, the coaches are optimistic about placebo use in sports. Close to half of them, especially those coaching at higher levels of competition, may use it regularly while achieving positive results.
Drills are an important element of disaster management, helping to increase preparedness and reduce the risk of real‐time failure. Yet, they are not applied systematically to slow‐onset disasters such as a drought, which causes damage that is not instantly apparent and thus does not solicit immediate action. This case study evaluates how drills inform institutional responses to slow‐onset disasters. It spotlights Guatemala, a country where drought has severe impacts on livelihoods and the food security of small farmers. By implementing part of the Ministry of Agriculture, Livestock and Food's institutional response plan for drought, it explores how drills can help to detect issues in emergency response and to foster an institutional focus on improvements in preparedness. The results reveal that drills alone do not trigger institutional improvements if unsupported by a wider strategy that seeks to enhance capacities and protocols. These findings are valuable, however, in making problems transparent and in creating the space for discussion.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
