Las cifras de la documentación en España: 2002

The state of the Spanish LIS profession and specialities in 2002 is reviewed. Statistical data is provided about both the number and type of Spanish libraries and archives as well as of practising professionals, according to geographic distribution, training and job description. Spanish library and information authorities are identified as well as professional associations and learned societies and conferences held. University education is also examined with descriptions of existing institutions, degree levels and data on student enrolment and teachers. The primary media for professional communication are described, in particular, publishers, bulletins, scientific journals and electronic fora. Publishing output is quantified: books, journal articles, and conference papers both at national and international levels. Finally, research in the field is analysed through the total of Ph. D. dissertations presented, research articles published and research projects funded

Modelling extreme values by the residual coefficient of variation

The possibilities of the use of the coefficient of variation over a high threshold in tail modelling are discussed. The paper also considers multiple threshold tests for a generalized Pareto distribution, together with a threshold selection algorithm. One of the main contributions is to extend the methodology based on moments to all distributions, even without finite moments. These techniques are applied to euro/dollar daily exchange rates and to Danish fire insurance losses
