Anthropomorphic symbols on Neolithic vessels from Puglia
Full text linkIn Puglia, human representations on vessels were widespread from the Early Neolithic. Some of these have been interpreted as faces, but they could also be representations of the entire body complete with torso, arms and legs: these include some recently studied symbols from Grotta dei Cervi, which have been compared with others from Grotta delle Veneri, whose published descriptions are open to revision. From this starting point, the scope of the research was expanded to include all documented anthropomorphic symbols on Neolithic vessels from south-east Italy, taking account of their chronology, origin and context. It was possible to establish that in the sixth millennium BC, there were three different categories of human representation in Puglia: vessels decorated with human faces (face vessels), vessels decorated with wholebody human figures and vessels in the shape of human beings (anthropomorphic vessels). Some faces include all elements, while others have just some of them (e.g. the nose). In addition, some faces have extra elements such as bands or bundles of lines that can be interpreted as tattoos, beards, ornaments or clothes. The symbols may be representations of praying figures, dancers, high status or powerful members of the community, ancestors and even gods, who were tasked with either protecting the community or acting as an intermediary between the community offering the vessel and the deity of the underworld. This study examines the presence of these artefacts in settlements, caves and other cult sites, with the aim of describing this distinctive phenomenon that was particularly characteristic of Puglia during the Early Neolithic
L'orizzonte culturale del III millennio a. C.: il tumulo 7 di Salve (Lecce)
No full textIl tumulo 7 di Salve ha pochi confronti nell’eneolitico italiano per quanto riguarda architettura e ritualità. I materiali, invece, sono di facies Laterza e Gaudo, i primi con precisi rimandi a Grotta Cappuccini di Galatone, i secondi al sito campano di Taurasi.
Uno sguardo al III millennio europeo consente di inserire i tumuli di Salve in un fenomeno più vasto che coinvolge l’intera Europa attraverso processi di interazione tra culture diverse e geograficamente lontane, dalla Yamnaya al Campaniforme fino all’Antico Elladico
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
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
Dispelling the Myths Behind First-author Citation Counts
Full text linkWe 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
