Previous research on university-industry collaboration in Canada, using mean impact factors as a proxy, concluded that the scientific impact of such research is not inferior to that of university research. Using field-normalized impact factors and citation counts, this paper re-examines the...

Using the population of all university professors (N = 13,479) in the province of Quebec, Canada, this article analyses the concentration of funding, papers and citations at the level of individual researchers. It shows that each of these distributions is different, citations being the most...

In the recent debate on the use of averages of ratios (AoR) and ratios of averages (RoA) for the compilation of field-normalized citation rates, little evidence has been provided on the different results obtained by the two methods at various levels of aggregation. This paper provides such an...

Most current scientific policies incorporate debates on cities and the geographic organisation of scientific activity. Research on ‘world cities’ develops the idea that interconnected agglomerations can better take advantage of international competition. Thus, the increasing...

Purpose – The issue of duplicate publications has received a lot of attention in the medical literature, but much less in the information science community. This paper aims to analyze the prevalence and scientific impact of duplicate publications across all fields of research between 1980 and...
