obviously not an easy task to achieve a distortion-free evaluation of effects from a research assessment exercise when such evaluation is based on results over a period of time when there are changes in methodologies, criteria or indicators of the exercises
that the exploration of the evolution of NST in time and space is a theme of prime importance, given the strong implications this might have for policy, industrial economics, management of scientific research and technology transfer. In particular the
Abandonement rates of patents in five European countries are studied. The time distribution of British patents can be described by a truncated Gauss' distribution, of Belgian patents by a Poisson's distribution. Appropriate models derived on the base of the octogonal and cubical linear vector space norms are discussed.

countries using constant returns to scale (CRS). Tseng et al. ( 2009 ) used several trend indexes for time series with a view to detecting hot topics of research. Szydlowski and Krawiec ( 2009 ) analysed a series of 2,000 papers on symbolic logic published
Raan 2005 ). In turn, universities use such data for promotions and appointments as well as for encouragement measures.
Time series analysis of publication counts can successfully reflect modifications of policies at country or institutional
In this article, “Life time of influence” refers to Robert K. Merton's impact broadly, and emblematically, to his influence upon my work. The article discusses 1) the scope and influence of Merton's ideas about social structure and explanations of social processes; 2) his vast scholarship establishing the study of science as a social institution, with implications for theory and research; and 3) his fostering of the social study of science through immense published work, and through impact upon an inter-generational network of scholars.
Sequential estimation of parameters for time series observations is considered. The Chow-Robbins procedure is extended and
Wald’s identity is proven for such data. Various confidence bands are defined. These give simultaneous confidence intervals
for a sequence of sample sizes.
