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
Analisi geobotaniche nell’Area Marina Protetta di Tavolara – Punta Coda Cavallo (Sardegna NE) a supporto della gestione della biodiversità
No full text"Vengono presentati i risultati degli studi geobotanici realizzati per la definizione dei livelli di qualità ambientale dell’Area Marina Protetta (AMP) di Tavolara-Punta Coda Cavallo (Sardegna nord-occidentale). 1) Descrizione floristica dell’area: risultano 644 entità vegetali (26,7% della Flora Sarda), tra cui sono prevalenti le specie annuali (44,2%) e le stenomediterranee (35,2%). Le entità endemiche (9,2%) risultano superiori alla media regionale: di queste, quattro sono incluse nell’Allegato II della Direttiva 92\/43\/CEE conosciuta come “Direttiva Habitat”. 2) Descrizione delle comunità vegetali presenti: queste, seguendo il metodo fitosociologico, sono inquadrate in 54 associazioni e 3 aggruppamenti, riferiti a 20 classi di vegetazione. 3) Classificazione gerarchica del paesaggio: realizzata secondo una metodologia divisiva in 4 livelli, ha permesso di individuare sul territorio 8 unità ambientali, incluse in 7 sottosistemi, 2 sistemi e 1 regione di paesaggio (Mediterranea). 4) Individuazione e descrizione degli habitat comunitari: sono stati individuati e mappati 32 habitat comunitari (di cui 7 prioritari) ai sensi della Direttiva 92\/43\/CEE.""We present the results of the geobotanical studies carried out for defining the environmental quality of the Protected Marine Area (PMA) of Tavolara Punta Coda Cavallo (North-Eastern Sardinia) 1) Description of the flora: we found 644 plant species (26.7% of the Sardinian flora), among which the annual species prevail (44.2%). The endemic species (9.2%) are higher than the regional average. Four of them are included in the annex II of the Directive 92\/43\/EEC known as “Habitat Directive”. 2) Plant communities are described according to the phytosociological method. They are framed in 54 associations and 3 groupings, which are included in 20 classes of vegetation. 3) Hierarchical classification of the landscape was made following a 4-steps, dividing methodology: eight environmental landscape units have been identified, included in 7 sub-systems, 2 systems and a landscape region (Mediterranean). 4) Identification and description of UE community habitats: 32 habitats have been identified and mapped (7 priority) following the annex I of the Directive 92\/43\/EEC.

No full textVariations 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
