Rapporti tra tipi vegetazionali e substrato roccioso nell’area umbro-marchigiana.
No full textIn this area, Ostrya carpinifolia woods with Quercus cerris are related to the diffusion of "calcari diasprini". Quercus pubescens woods almost exclusively pertain to ares covered by nappe detritus and calcareous-marly detritus; woody communities of Quercus cerris are explained by the presence of fersiallitic paleosols

No full textThe Altipiani di Colfiorito are a system of seven tectonic depressions with karstic phenomena, located in the Umbria-Marches Apennine ridge (Italy). This area is characterized by the presence of wetlands which have been internationally protected through the institution of a Ramsar Site, an Important Bird Area, three Sites of Community Importance and a Special Protection Area. The analysis of bibliographic and herbarium data and the floristic field research carried out from 1999 to 2008, allowed to list 657 floristic units, belonging to 88 families and 320 genera. Among them, 11 (Avena sativa subsp. macrantha, A. sterilis subsp. ludoviciana, Chenopodium hybridum, Cuscuta campestris, Mentha arvensis, Rosa andegavensis, R. dumalis, Schedonorus uechtritzianus, Scrophularia umbrosa, Trifolium alexandrinum and
Veronica catenata) are new for the Umbrian flora and 2 (Crypsis alopecuroides and Schedonorus uechtritzianus) for the Marchean flora. Numerous rare and threatened species in Umbrian and Marchean flora, such as Alopecurus bulbosus, Carex tomentosa, Equisetum fluviatile, Juncus hybridus, Nymphaea alba, Ophioglossum vulgatum, Ranunculus flammula, R. ophioglossifolius, Trifolium patens and Utricularia australis, have been found. Nevertheless some species, previously recorded for Palude di Colfiorito, such as Eriophorum latifolium, Hippuris vulgaris, Hydrocotyle vulgaris, Menyanthes trifoliata, Potamogeton lucens, P. trichoides, Ranunculus lingua and Triglochin palustre, were not found and considered locally extinct
Sulla distribuzione dei paleosuoli fersiallitici e dei boschi a Quercus cerris L. nel territorio del Foglio n. 324 (Foligno).
No full textLo studio mette in evidenza lo stretto rapporto tra substrato roccioso e copertura vegetale. Attraverso cartografie dettagliate vengono messe in evidenza le variazioni composizionali all'interno delle formazioni rocciose, la composizione particolare di coperture continentali e i particolari contesti dell'evoluzione geomorfologica, passa e in atto

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
