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
Segnalazione per la flora siciliana di Trifolium ornithopodioides L. (Fabaceae) e revisione della sua area di distribuzione.
No full textTrifolium ornithopodioides (L.) Sm. (Fabaceae) a new record for the Sicilian flora – T. ornithopodioides, a rare element of the Italian flora, is recorded for the first time in the territory of Palermo (Western-Sicily). The population identified, consisting of about one hundred individuals, colonizes a narrow area between the roadside and the edge of the freshwater temporary pond of Rebuttone, on acidic substratum (flysch) at 720 m a.s.l. After the examination of herbarium specimens (RO and FI) and literature, some incongruences have been found on the Italian distribution of this taxon. A distribution map including the new record, new literature data and corrections is presented
Spatial and temporal evolution of mining-induced sinkholes in the Gavorrano area (Tuscany, Italy): Insights from remote sensing and field data
No full textThe failure of underground cavities and the formation of sinkholes is a major risk at both active and dismissed mining areas. However, while ground deformation related to most active mines is constantly monitored today, the ground instabilities around historical and dismissed mining areas often remain disregarded. Here, we combined a multidisciplinary dataset of historical mining reports and maps, aerial images, field measurements and InSAR observations to reconstruct the spatial and temporal evolution of ground deformation around a sinkhole prone area in the mining district of Gavorrano (Tuscany, Italy). We identified the three sinkholes of Monte Calvo, Valsecchi, and Ravi, with the latter two never reported in literature. The three sinkholes have a spatial correlation with the underground cavities and galleries of major mines. InSAR observations between 20162022 also revealed that an area of ∼ 700 m × 400 m around the Monte Calvo sinkhole is still subsiding with rates of ∼5 mm/yr. Conversely, no clear evidence of deformation is observed at Valsecchi, Ravi, and the nearby city of Gavorrano. Our observations suggest that the sinkhole activity in Gavorrano has been induced by the mining activity in the area and that subsidence is still ongoing at Monte Calvo
Appropriate Similarity Measures for Author Cocitation Analysis
Full text linkWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Primo contributo lichenologico nella Riserva Naturale Orientata di Bosco della Favara e Bosco Granza (Sicilia centro-settentrionale).
No full textOggetto del nostro contributo il censimento della flora lichenica del territorio di Montemaggiore Belsito facente del sito ZPS ITA020032 “Boschi di Granza e Bosco di Favara.Il territorio in esame ampiamente studiato dal punto di vista vegetazionale e floristico relativamente alle fanerogame (2), non risulta finora studiato sotto l’aspetto lichenico .L’area in esame è denominata Valle del Torto ed è compresa nella tavola I.G.M., 1:25.000, F. 259 I: S.O. (Montemaggiore Belsito). Essa si estende su un ampio territorio ricadente nei comuni di Montemaggiore Belsito, Cerda, Sclafani Bagni, Caltavuturo e Caccamo. Tale studio appare significativo per comprendere il mosaico delle conoscenze floristiche del territorio siciliano, perchè a causa delle continue manomissioni e dei frequenti incendi queste si vanno irreversibilmente depauperando. L’area di studio dal punto di vista geologico Il territorio è costituito in prevalenza da facies arenacee associate a facies conglomeratico-arenacee del miocene inferiore - oligocene superiore(1),. Termotipo mesomediterraneo in prevalenza e a quote più elevate il supramediterraneo subumido. L’indagine floristica preliminare ha portato al riconoscimento di 88 entità distribuite in 34 generi. Tra queste Sarcogyne clavus (DC.) Kremp. Ionapsis ceracea (Arnold) Hafellner et Türk. risultano nuove per la Sicilia. Lasallia pustulata (L.) Mérat e Rinodina obnascens (Nyl.) H.Olivier. pur se già note risultano estremamente localizzate. Analizzando lo spettro delle forme di crescita emerge una condizione di equilibrio tra le forme fogliose (43%) e crostose (40.7%); di minor importanza la componente fruticosa (12.8%) e squamulosa (3.5%). Per ciò che concerne i substrati colonizzati la maggior parte delle entità censite è epifita (31%); seguono i licheni rupicoli (54%) ed i terricoli (14%). La nomenclatura utilizzata segue ITALIC(3)
