Análisis de la relación entre disciplinas a través del uso de tesis doctorales. El caso de Televisión, Radio, Cine y Fotografía en España

. This paper proposes a new method of analysing the relation between disciplines measuring academic participation in doctoral theses across different disciplines. Methodology: Doctoral theses and the relationships produced through the direction of theses and co-participation in doctoral thesis examination committees are used to construct the interdisciplinary relationships. This study uses doctoral theses defended in Spain in the field of audiovisual communication (television, radio, film and photography) for the period 1976-2007 as an example. Multidimensional scaling allows us to create a bi-dimensional representation of the specialties studied, calculate distances and quantify the degree of error of the representation. Results and Conclusions: The results demonstrate how two differing groups are produced, firstly television and radio and secondly film and photography. Television is the most representative specialty of the group; the different types of participation produce hardly any variations.
