Habitat richness affects home range size in the red fox Vulpes vulpes
No full textThe spatial behaviour of the red fox Vulpes vulpes shows a great flexibility (Voigt and Macdonald, 1984). Home range size varies from 10 to over 5000 ha (Macdonald, 1987; Voigt, 1987). In carnivores, variations in home range size, weighed for body mass (Gittleman and Harvey, 1982), are largely related to differences in habitat productivity, but the intraspecific local variation in home range size can be only partially explained by differences in productivity. Macdonald (1981, 1983) suggested that home range size and configuration were determined in the red fox by the dispersion of food-rich patches. More recently, it has been found that (a) where humans are intolerant to the fox, resting sites are often located peripherally in home ranges (Meia and Weber, 1993); (b) the ranging behaviour of red foxes cannot be explained only by the features of food resources in a complex environment with several productive habitats (Cavallini and Lovari, 1994); and (c) home range size may be directly related to the distance between rest sites and food patches (Lucherini et al., in press). In this paper, evidence for a strong influence of habitat richness on home range size of the red fox is reported

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

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
Rimembranza e perennità dei cavalieri angioini dell’Ordre du Saint-Esprit au Droit Désir (Napoli, 1352)
No full textIl saggio prende in esame da un'ottica inedita il celebre manoscritto miniato contenente gli Statuts de l'Ordre du Noeud, coservato a Parigi (BnF, Français 4274) e miniato a Napoli intorno al 1353 da Cristoforo Orimina. Oggetto di numerosi interventi critici negli ultimi decenni, il codice non è mai stato indagato dal punto di vista dello studio delle tombe monumentali napoletane trecentesche. Eppure non solo le prescrizioni statutarie dell'ordine cavalleresco dedicano diversi capitoli alla questione sepolcrale, ma le carte 9r e 9v mostrano tipologie sepolcrali che possono sicuramente confrontarsi con tombe angioine ancora conservatesi a Napoli: il sarcofago su colonnine reggente un gisant e il sarcofago inserito in una struttura più complessa, con le basi poggiate su leoni scolpiti e figure che affiancano il gisant. Nell'articolo si prendono in esame queste componenti, si analizza il testo corrispondente, vi si individua la volontà programmatica di perpetuare il nome dei cavalieri attraverso le memorie funerarie e si mette in parallelo tale volontà con l'operazione di scrittura di un libro contenente le avventure degli stessi cavalieri, secondo una pratica riscontrabile, ad esempio, nel Tirant lo Blanch dello scrittore valenziano Joanot Martorell. L'approccio di metodo è interdisciplinare, chiamando in causa storia, storia dell'arte e letteratura medievale
