A bibliometric analysis in the emerging field of bioelectronics, characterised by a high degree of interdisciplinarity, is carried out. Two different techniques — co-classification and co-word analysis — have been used and their results have been compared. The limitations and potentials of these techniques, especially concerning their use for analysing interdisciplinary scientific fields, are discussed. It is found that these techniques enable analyses gaining a first insight into the coarse structure of the field. The advantage of the techniques is their relative simplicity, and the possibility to carry out trend analyses based on relatively constant classifications of research activities, so that maps of different time periods become comparable and changes within the structure of the field become visible.
Collaboration and cross-disciplinarity are important features in autoimmune disease research. Taking co-authorship as an indicator
for research collaboration, for selected European countries it was found that 91% to 99% of all publications are based on
collaboration. International collaboration affects about 27% of all publications. Small countries like Sweden and Finland
pursue international collaboration more intensively than larger countries like Germany or the UK. Different collaboration
strategies were found for nationally co-authored papers, for instance, Germany seems to focus more on intra-departmental collaboration,
while France and Italy have stronger inter-institutional links. About 54% of all publications are based on cross-disciplinary
The efficiency of areas of science was evaluated using the DEA method. Areas achieving a maximum orientation or regard of international publication are rated as efficient. The areas of reproductive medicine, organic and inorganic chemistry in the former Federal Republic can thus be regarded as efficient areas of science. No area of scientific research in the former East Germany was able to achieve the optimum. The determinant in this connection is the adverse situation with respect to international orientation whilst no substantial difference in regard for further research could be detected between East and West German research.
This study analyses activities in new biotechnology in food science and technology using bibliometric methods. Multidimensional scaling is used to visualise the structure of the field as represented by scientific literature and patent applications. For the science as well for the technology side increasing activities in the field were found. The specialisation analysis shows above average specialisation at the science and the technology side of the EU member countries (except for Germany) as well as for the USA. Within the EU also less developed countries intensified their R&D activities. At the science side aspects of food safety and quality are highly relevant. These topics are also tackled at the technology side but, compared to the science side these sub-fields seem to be still more isolated within the structure of the field. Structural differences between the science and the technology side partly may be explained by special features of the patent law in biotechnology.
