Towards the identification of species-specific monitoring protocol for the Italian flora of Community interest
The ongoing activities for the identification of monitoring methods for the Italian flora of Community interest (FCI) are presented. The reference framework is the Directive 92/43/EEC. Monitoring is an obligation arising from Art. 11 and the results have to be reported every six years, according to Art. 17. In the last Italian National Report, covering the period 2007-2012, the status of the FCI was assessed using available knowledge and expert judgment, still revealing relevant lack of data for some plant species and, in turn, population parameters (Ercole and Giacanelli, 2014). To overcome these deficiencies, in 2015 began a project aims to set future monitoring activities and to optimize…
Ranking Scientific Journals Via Latent Class Models for Polytomous Item Response Data
Summary We propose a model-based strategy for ranking scientific journals starting from a set of observed bibliometric indicators that represent imperfect measures of the unobserved ‘value’ of a journal. After discretizing the available indicators, we estimate an extended latent class model for polytomous item response data and use the estimated model to cluster journals. We illustrate our approach by using the data from the Italian research evaluation exercise that was carried out for the period 2004–2010, focusing on the set of journals that are considered relevant for the subarea statistics and financial mathematics. Using four bibliometric indicators (IF, IF5, AIS and the h-index), some…
