Genetic and morphometric comparison between Sorex arunchi Lapini and Testone, 1998, and other shrews from Italy
No full textThe results of allozymic, morphologic and morphometric studies performed on three parapatric shrews of the genus Sorex from northern Italy are presented. These data clearly indicate: (1) Sorex samniticus is genetically well differentiated from S. araneus and S, arunchi, displaying a high mean value of genetic distance in comparison with the other two species (D = 0.463). (2) S, araneus and S. arunchi display low values of genetic distance (D = 0.007) and the latter shows lower levels of genetic variability. Altough no fixed allele difference was observed, an exclusive allele (Lap-2(96)) is present in S. arunchi at low frequence, another one (Pgm-1(96)) is rare in S. araneus and quite frequent in S. arunchi, and several alleles (12) of S. araneus are missing in S. arunchi. In S. araneus some of these alleles are quite frequent. (3) Strong morphometric differences between S. araneus and S. arunchi permit to distinguish these parapatric shrews with great accuracy, also in some cases of marginal sympatry. These evidences support the hypothesis that S, arunchi might be a recent (end of Pleistocene-lower Holocene) relict of the subgenus Sorex s. s

Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
A proposito dell’aristotelismo rinascimentale: prospettive di traduzione e di interpretazione
No full textL’articolo analizza le ricadute sul pensiero aristotelico e le sue interpretazioni rinascimentali determinate dai nuovi impulsi offerti, insieme all’avvento della stampa, dalle nuove traduzioni umanistiche. In particolare si analizza il nuovo metodo di traduzione umanistico a partire dal fondamentale contributo del Bruni nel suo De recta interpretatione. Inoltre si mostrano le molteplici relazioni esistenti fra l’aristotelismo rinascimentale e le altre correnti e tradizioni filosofiche evidenziando come non si possa parlare dell’aristotelismo rinascimentale al singolare, ma sia necessario volgere il termine al plurale se si vuol dar conto della vasta complessità del movimento peripatetico nel XVI secolo
Variations on the Author
Full text link“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
