Improving the visibility of hydrological sciences from developing countries

Abstract

The increasing level of competition in scientific publishing arguably has a greater negative impact on hydrologists from developing countries and specifically young scientists. This paper discusses the constraints they face and offers suggestions to authors and the hydrological community about how these may be mitigated. These include a lack of access to resources to assist with creating good publications, the difficulty of publishing research based on relatively scarce data, a common problem in many developing countries, and a lack of familiarity with the process of publishing scientific material together with limited access to mentorship from experienced authors. A key point is to ensure that the research question addressed has a broad interest beyond the local study area. However, the more limited hydrological knowledge and the water resources problems of developing countries represent opportunities for internationally relevant research, particularly within the nexus between hydrology and society, or between science and practice. Both of these are high on the international hydrological research agenda.

Publishing and publishers: towards an historical geography of countryside writing, c. 1930-1950

The role of publishers as cultural agents is under-researched by those who have made use of the extensive canon of twentieth-century countryside writing. This paper calls for an historical geography of publishing, which treats publishers as a vital element in the production and circulation of knowledge.     

The impact of new media on 20th century astronomy

This paper offers a few comments on the impact and changing sociology of astronomy information handling over the past century (especially its last third), drifting from individual measurements or records to catalogues and data centres, and moving recently from information hubs to distributed digital research facilities including the current projects of so‐called ‘virtual observatories’. After an introductory part and some notes on personal experience, the paper discusses data centres, methodologies, electronic publishing, as well problems and challenges inherited from the new media: fragility, security and ethics, not to forget the most important one, quality.
