    Un eclettismo programmatico: il caso di Petitot

    No full text
    Oltre ai legami storici, culturali e dinastici tra il Regno di Sardegna e i ducati borbonici di Parma, Piacenza e Guastalla, si indagano i caratteri della produzione architettonica e artistica di E.A. Petitot (Lione 1727-Parma 1801), ispirati a una posizione estetica per alcuni aspetti simile a quella di Benedetto Alfieri. Entrambi fanno parte di un gruppo di architetti che durante il Settecento praticato consapevolmente un eclettismo stilistico di matrice encyclopédique, in cerca delle tonalità e delle forme più consone a ogni funzione architettonica, decorativa e celebrativa

    Detailed histopathological and immunohistochemical studies were carried out on 24 cetaceans, 17 of which were striped dolphins (Stenella coeruleoalba), four bottlenose dolphins (Tursiops truncatus) and three Risso's dolphins (Grampus griseus), all found stranded on the Italian coast between 1990 and 1997. The most frequently detected lesions were chronic pneumonia (73.7% of the examined lungs), focal chronic pancreatitis (71.4%), non-purulent encephalitis (50%), chronic hepatitis (42.1%), and chronic focal interstitial nephritis (31.2%). The skin and the subcutaneous panniculus were often (33.3%) affected by parasitic diseases (Phyllobothrium delphini and Pennella sp.). An appreciable percentage of animals showed lymphoid depletion in their lymphatic organs (47.2%), as well as a high rate of parasitic infestations in their alimentary tracts (25%).[...

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
