Prehistoric lithic industry from a layered Etruscan-Po valley context
No full textIl presente lavoro è incentrato sull’analisi dell’industria litica preistorica rinvenuta in giacitura secondaria nell’insediamento etrusco-padano del Forcello di Bagnolo S. Vito (MN). Nei circa trent’anni di campagne di scavo condotte dall’Università degli Studi di Milano sono venute alla luce tre asce in pietra levigata e 123 reperti in selce scheggiata, che comprendono lame, schegge, nuclei, scarti di lavorazione e strumenti. Si è cercato, dunque, di inquadrare cronologicamente ogni reperto attraverso un’attenta analisi tipologica e confronti puntuali con materiali analoghi provenienti da contesti stratigrafici certi, considerando in particolare i ritrovamenti finora noti nel comune di Bagnolo S. Vito e zone limitrofe. Si è, inoltre, cercato di comprendere le cause che hanno portato al recupero di reperti pre- e protostorici in un contesto di VI-IV secolo a.C. attraverso l’analisi e l’interpretazione delle unità stratigrafiche di rinvenimento.This work is focused on the analysis of the prehistoric lithic industry found in secondary context in the Etruscan settlement of Forcello di Bagnolo S. Vito (MN). During thirty years of excavations, the University of Milan had found three axes and 123 flint artifacts, such as blades, flakes, cores and instruments. Here I analyze every artefact from a typological point of view and try to put them in the right chronological bounds, finding comparisons with similar objects from certain stratigraphical contexts from Bagnolo S. Vito’s territory and neighborhoods. I also try to find out how they arrived there, in a VI-IV century B.C. settlement, through the examination and interpretation of every stratigraphical unit in which they were found
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
Foil disks in the early Iron Age: the case of the necropolis of Chiavari
No full textLa necropoli a incinerazione di Chiavari risale all’VIII-VII secolo a.C. Si analizzano in questo lavoro ventuno dischi in lamina con foro centrale, tre in argento e diciotto in bronzo, rinvenuti in diciannove contesti, di cui si da conto. I dischi meglio conservati rientrano nel ‘tipo Chiavari’, caratterizzato da una decorazione a ruota raggiata. Delle due varietà di decorazione individuata si propongono confronti morfologici e funzionali con altri dischi in lamina dell’Italia settentrionale.
The cremation burials of the necropolis of Chiavari date back to the 8th and 7th century BCE. This contribution explores twenty-one foil disks with a central hole: three of silver and eighteen of bronze, found in nineteen graves. The best-preserved disks belong to the ‘Chiavari type’ decorated with a radial-spoked wheel motif. The two varieties of decoration are compared, in terms of shape and function, with other similar examples from Northern Italy
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
