Trends in research output

Research Output is the whole of publications and public appearences from academic mployees at universities. Researchoutput is therefor more than only scientific publications. Although Dutch researchers publish in academic journals, they also contribute to professional journals, a wide variety of (trade)magazines and appear in the media.
Reliable data is not available on all types of research output: keeping track of publications or appearences that led to a research output is arbitrary and difficult to assess. Also because of the invisibility of some of these publications and appearences. all this means that not all research output is properly recorded. 
An exception to this is the research output of scientific publicatons and their specialization: dissertations (theses of PhD's. Note: in the Netherlands PhD's have the status of academic staf). This is recorded (reasonably) well in the administrative systems. The output from this systems is collected annully by the bureau of the Universities of the Netherlands, by means of the so called KUOZ request.
Please note: different numbers of publications emerge from other data collectionhs, suc as Scopus or Web of Science. The data shown below is based entirely on he KUOZ outcome.

Scientific Publications

A scientific publication is a publication that is primarily aimed at the forum of (scientific) researchers. Scientific publications have specific characterisctics such as: emphasis on the research process, methodological underpinning and reference to previous research reslts. The relationship between these characteristics can differ per discipline.
The aim of a scientific publication is to contribute to increasing scientfic knowledge. Publications that focus on the research carried out by others, like meta-analyses, overview articles or scientific reviews. also contribute to the increase of scientific knowledge through this clear added value.
The numer of scientific publications in the year 2020 will be more than 25.000 scienti publications higher that in the year 2000.

Dissertations (in Dutch: also called: proefschriften) constitute a separate category of academic publications, and are also used to measure the number of doctorate conferrals at Dutch universities. The number of dissertations accepted since 2000 doubled. 
What is striking is that the number of dissertations differs significantly from the number of doctorate conferrals. This is due to the fact that almost 50% of people pursuing a doctorate are not employed by Dutch universities (as PhD's), but are nevertheless supervised by professors and senior university lecturers during their PhD track.
