    The volcanic and seismic hazard that the Aeolian archipelago is subject to urges detailed multidisciplinary studies on those potentially destructive events that probably occurred as volcanism developed along with local anthropogenic history over the last 7500 years. By examining the oldest human settlements in the Aeolian Islands, from which we may deduce the population density, as well as the behaviours and lifestyles of the inhabitants, the aim was to identify a link between the sudden and irregular cultural changes and the natural calamities recorded in the profuse Aeolian volcanological literature [Gillot and Keller, 1993; Kokelaar and Romagnoli, 1995; Rosi et al., 2000; Tinti et al., 2002; Speranza et al., 2008; Calvari et al.,2011; Francalanci et al., 2013]. Recent radiometric and paleomagnetic dating have established that significant phenomena affected Stromboli during its 5th life cycle between 13,000 and 4000 BP (Neostromboli). In particular, a major eruptive phase ended about 7500-7000 years ago, followed by a period of quiescence lasting roughly 3000 years when the volcano, having reached its maximum expansion of the north sector and undergoing structural instability, was affected by massive collapses, after that of Vàncori about 13,000 years ago. These were the main and most recent landslides leading to the formation of the Sciara del Fuoco [Tinti, 2002; Francalanci et al., 2014]. Concerning the major collapse of Neostromboli, the ensuing tsunami certainly had disastrous effects along the southeastern Tyrrhenian coasts, as deduced by Tinti et al. [2002] through numerical simulations. Though investigating the dynamics causing the collapses of the sector is beyond the scope of this paper, it is possible that different phenomena such as seismic events or coastal erosion, may have caused the landslides. This would relate the two major collapses of La Sciara with the two profound economic and demographic crises marking aeolian prehistory at the beginning of the 3rd and the 1st millennium BC respectively.Published1-201V.

    Going Beyond Counting First Authors in Author Co-citation Analysis

    The 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

    “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

    Full text link
    We 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

    Full text link
    We 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 text
    We 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

    La Chiesa come corpo cosmico del Cristo fra eternità e temporalità nell’antifona 'O eterne Deus' di Hildegard von Bingen

    Riassunto: Il presente saggio tratta del canto antifonale O eterne Deus composto da Hildegard von Bingen e inserito nella sua raccolta liturgica intitolata Symphonia armonie celestium revelationum. Il testo critico del canto è preceduto da un’analisi della sua tradizione manoscritta e seguito da una traduzione originale in italiano; è fornito anche di una guida analitica alla sua interpretazione, che include osservazioni sui suoi principali fattori strutturali, retorici, linguistici e ipotestuali. La guida all’interpretazione del canto è necessaria per un primo concreto approccio alla complessa stratificazione dei significati propria della poesia di Hildegard, che fa un uso molto ampio di simboli, tropi ed allusioni alla tradizione biblica e patristica. L’immaginazione mistica di Hildegard sembra essere uno strumento di codificazione per un sistema di comunicazione molto complesso e disposto su molteplici livelli di significato. Abstract: This essay deals with the song O eterne Deus composed by Hildegard von Bingen and inserted in her lyturgical cycle called Symphonia armonie celestium revelationum. The song’s critical text is preceded by an analysis of its manuscript tradition and followed by an original translation in Italian; it is provided also with an analytical guide to its interpretation, that includes remarks on its main structural, rhetorical, linguistic and hypotextual factors. The guide to the interpretation of the song is necessary to a first reliable approach to the complex stratification of the meanings of Hildegard’s poetry, that makes a very ample use of symbols, tropes and references to biblical and patristic tradition. Hildegard’s mystical imagination seems to be an encoding instrument for a very complex communication system disposed on manifold levels of meaning
