Abstract
For policy-makers and managers of research organizations, improvement in performance is a constant objective. The potential presence of returns to scope of fields of research could influence decisions in planning the fields of activity of the research organization and the spatial positioning of its researchers in function of their specializations. We investigate the possible presence of returns to scope and the relation between scope of fields in an organization and intensity of interdisciplinary collaboration. The results, from analyzing the scientific collaborations of Italian university researchers over the years 2004–2008, seem to indicate that in general the scope of the research fields has no impact on the productivity of research or the intensity of interdisciplinary collaboration.

As an example, we quote the SDS description for FIS/03-Materials physics: “The sector includes the competencies necessary for dealing with theory and experimentation in the state of atomic and molecular aggregates, as well as competencies suited to dealing with properties of propagation and interaction of photons in fields and with material. Competencies in this sector also concern research in fields of atomic and molecular physics, liquid and solid states, semiconductors and metallic element composites, dilute and plasma states, as well as photonics, optics, optical electronics and quantum electronics”.

In the Italian academic system, the hard sciences are matched in nine UDAs: mathematics and computer sciences; physics; chemistry; earth sciences; biology; medicine; agricultural and veterinary sciences; civil engineering; industrial and information engineering.
As frequently observed in literature (Lundberg 2007), standardization of citations with respect to median value rather than to the average is justified by the fact that distribution of citations is highly skewed in almost all disciplines.
The subject category of a publication corresponds to that of the journal where it is published. For publications in multidisciplinary journals, the standardized value of citations is obtained averaging the standardized values for each subject category .
The weighting values were assigned following advice from Italian professors in the life sciences. The values could be changed to suit different practices in other national contexts.
Considering, for publications in the life sciences, the position of authors in the list and the character of the co-authorship (intra-mural or extra-mural).
A “non-active” scientist is one having nil FSS.
A “top” scientist is one with position above 80th percentile in ranking by FSS, among all national colleagues of the same SDS and academic rank. “Top scientist concentration” greater than 20 % indicates that, for the research staff in an SDS of an individual university, the percentage of top scientists is greater than the national average value.
Kendal’s tau-b index assumes values between -1 (maximum discordance) and +1 (maximum concordance), with neutral value of 0 in cases of absence of association.
AGR/02_AGR/04, AGR/09_FIS/05, BIO/03_BIO/01, BIO/13_BIO/11, VET/01_MED/17.
