Mauro Degli Esposti Towards a new model for evaluating the merit of Italian academic scientists and their institutions Ferrara, Jan 2011
A new analysis of Italian universities – the start From The Times October 9, 2008 Whatever happened to the University of Bologna? The University of Bologna, which received its charter from Frederick I Barbarossa in 1158, was probably the first university founded in the Western world. It became a renowned home to scholars of great distinction in both the sciences and the humanities. The Times Higher Education-QS World University Rankings survey was published this week. It rates the performance of universities according to the quality of their research, the employment rates of graduates and their international profile. The University of Bologna does not feature in the top 100! Manchester = 29 – now 26 Harvard = 1, Cambdrige = 3, Oxford = 4, UCL = 7...

MERIT – a new approach to evaluation M Degli Esposti, presented at the first conference of Via-academy, 21 September The members of the Via-academy network who work in UK have been selected on the basis of merit, but educated in Italy. The number of academic links of Via-members with Italian institution will be proportional to the relative teaching capacity of these institutions – i.e. they will be an output measure of their quality and relative standing.

Different Area – different impact (publications and citations) Normalization? By which criteria? Which database to use for reference? M Degli Esposti, September, 2010 – retrieved from: Manueletto del Ricercatore Provetto NOT ISI WoS!
Scientometrics 73 (2007) The normalization factor follows a stretched exponential; it becomes bigger by increasing the number of published articles For scientists with less than 50 published articles, the field- specific differences are small

Area-specific analysis of h-index using average values of top Italian scientists as reference 2.

Questions? Simple model for auto-evaluation in specific disciplines within a university Set a threshold of intrinsic (local) excellence by applying this formula: Threshold = average + SD + 1 (in absolute value of h-index) For example, Ferrara chemists: Threshold = = 24
