This article analyses the effect of degree of interdisciplinarity on the citation impact of individual publications for four different scientific fields. We operationalise interdisciplinarity as disciplinary diversity in the references of a publication, and rather than treating interdisciplinarity as a monodimensional property, we investigate the separate(More)
We estimate the determinants of university patents by route in Spain. National patents are an indicator of R&D efforts when we focus on the region, but not of how regions organize their university or joint research structure. International patents are a stronger indicator of R&D efforts, so they express confidence in the potential of the patent. Neither set(More)
The main objective of this contribution is to test whether university patents share common determinants with university publications at regional level. We build some university production functions with 1,519 patents and 180,239 publications for the 17 Spanish autonomous regions (NUTS-2) in a time span of 14 years (1988–2001). We use econometric models to(More)
Editorial delay, the time between submission and acceptance of scientific manuscripts, was investigated for a set of 4,540 papers published in 13 leading food research journals. Groups of accelerated papers were defined as those that fell in the lower quartile of the distribution of the editorial delay for the journals investigated. Delayed papers are those(More)
Median age difference (D) is obtained by subtracting median value of the age distribution of references of a scientific paper from citing half life of the journal that published it. Such an indicator can be related to the state of knowledge of research groups and can show some interesting properties: 1) it must be related with the incorporation of(More)
In September 2015 Thomson Reuters published its Ranking of Innovative Universities (RIU). Covering 100 large research-intensive universities worldwide, Stanford University came in first, MIT was second and Harvard in third position. But how meaningful is this outcome? In this paper we will take a critical view from a methodological perspective. We focus our(More)
