I Gessi di Brisighella e Rontana. Studio multidisciplinare di un’area carsica nella Vena del Gesso romagnola
No full textIl volume, sviluppatosi sotto l'egida della Federazione
Speleologica Regionale dell'Emilia-Romagna, del Parco regionale
della Vena del Gesso Romagnola e del Servizio Geologico, Sismico e dei
Suoli della Regione Emilia-Romagna, analizza i gessi messiniani posti
in Comune di Brisighella (RA), appartenenti alla dorsale evaporitica
nota come Vena del Gesso. Gli studi, spiccatamente multidisciplinari e
corali (sono oltre 50 gli autori che hanno contribuito alla
monografia), spaziano dalla geologia, alla speleologia, agli studi
naturalistici, all'archeologia, a temi storico-geografici e
gestionali
L’analisi degli elementi trutturali lignei della miniera di Perticara
No full textVengono qui presentati i risultati delle analisi xilologiche effettuate come saggio su dodici elementi strutturali lignei della miniera di zolfo di Perticara (Novafeltria, RN). L’individuazione dei taxa utilizzati per la realizzazione delle armature e di altri elementi della miniera fornisce uno spunto per fare ipotesi sull’utilizzo di risorse vegetali locali o provenienti da altri luoghi, al fine di fornire altre informazioni sul sistema-miniera nel suo complesso
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Evoluzione speleogenetica del sistema carsico del Re Tiberio (Vena del Gesso Romagnola)
Get PDFSe l’esplorazione dei fenomeni carsici profondi di Monte Tondo (Vena del Gesso Romagnola) può dirsi praticamente conclusa, poco invece è stato fatto per definirne globalmente l’evoluzione speleogenetica nel tempo.
La presenza di alcuni livelli suborizzontali ben sviluppati, non solo all’interno della Grotta del Re Tiberio, ma anche in molte altre cavità facenti parte dello stesso sistema, ha permesso, per la prima volta, di tentare la correlazione di questi livelli con i terrazzi fluviali della valle del Senio (corrispondenti ai livelli di base carsici del periodo) e quindi di definire a grandi linee l’evoluzione temporale di questo carsico, che, se si tralasciano i piccoli e rari fenomeni intramessiniani, è di gran lunga con i suoi oltre 150.000 anni, la più antica cavità nei gessi dell’Emilia Romagna.
Lo studio ha permesso anche di evidenziare come, nelle grotte in gesso, la velocità di adattamento delle forme carsiche ipogee alle variazioni climatiche esterne sia molto rapido e in particolare le gallerie antigravitative si possano correlare con i periodi di aggradazione dei terrazzi nel periodo immediatamente successivo ad una fase fredda, di cui quindi possono essere considerati degli indicatori
Variations on the Author
Get PDF“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
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe 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
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
