The Western European science policy establishment often claims that US articles are more frequently cited than articles of
the European Union's scientists because they are published in journals with a large number of US publications and that these
journals are forming the ‘core’ of the SCI.
For the disciplines covered by the SCI, no significant correlation has been found between the ratio of the average number
of citations per publication for publications with at least one EU address and at least one US address, respectively, on the
one hand, and, on the other hand, the ratio of the corresponding number of publications per journal.
This article presents an exploratory analysis of publication delays in the science field. Publication delay is defined as
the time period between submission and publication of an article for a scientific journal. We obtained a first indication
that these delays are longer with regard to journals in the fields of mathematics and technical sciences than they are in
other fields of science. We suggest the use of data on publication delays in the analysis of the effects of electronic publishing
on reference/citation patterns. A preliminary analysis on a small sample suggests that—under rather strict assumptions—the
cited half-life of references may be reduced with a factor of about 2 if publication delays decrease radically.

The study tries to analyze regional technological capabilities, linking technological positions to economic strength of the
region. To measure this link, we correlate the EPO patent data with trade data to assess the degree to which technological
advantages are translated into comparative advantages for the Flemish region in Belgium. The analysis for Flanders provides
some interesting insights. Following the skewed distribution of firms, the technological areas in which Flanders is able to
build, a strong position are very specific: printing technology, weaving technology, photography and recently also telecommunications.
Weak positions are outspoken in car technology. Linking these strengths and weaknesses in technological areas to economic
activity revealed an important mismatch between both. Most of the Flemish patents are in sectors without any comparative advantage,
while most of the sectors where Flanders does hold a comparative advantage, like chemicals and pharmaceuticals, do not show
strong technological advantages in terms of patents. Given the mismatch that was detected between technological positions
and economic advantages, it is of crucial importance to better understand the (missing) links between the various actors in
the regional innovation system. The analysis points out two important issues. The large and growing number of foreign applications
to Belgian/Flemish inventors and the large number of subsidiaries of foreign firms among Belgian/Flemish applications illustrate
the pervasiveness of the foreign dimension in the Belgian/Flemish technological landscape. Also very specific to the Belgian/Flemish
situation, is the limited importance of universities or research centers in terms of patenting activities.

This article addresses the following issues: How did external funding of Flemish academic research develop during the 1980's
and early 1990's? What are the effects of the increase of external funding on the size and the composition of the research
capacity in Flemish universities, and on research performance as reflected in bibliometric indicators? We present results
of a quantitative analysis of 340 research departments in the natural and life sciences at three Flemish universities. We
found that the externally funded research capacity increased strongly and is more and more concentrated in a limited number
of departments. Departments with a high international standing have profited more from external funds than groups with a low
impact. In the class of departments showing the strongest increase in the externally funded research capacity, the ratio of
the number of junior and senior scientists in these departments increased radically, while the publication productivity decreased.
Our findings point towards the problem that if these trends continue to develop, a situation may emerge in which the basis
normally provided by the university itself has become too small for externally funded research activities.
