Bioarchaeological and Paleopathological Analysis of a Burial from the Late Roman Necropolis of Pianotta di Calatabiano (CT, Sicily)
No full textThis contribution focuses on the human osteological remains recovered from a tomb in the necropolis of Contrada Pianotta di Calatabiano (Catania, eastern Sicily). In antiquity, this fertile, water-rich land along the Via Pompeia connecting Messina to Syracuse was ideal for intensive agricultural exploitation. In the 1990s this site was subjected to an early archaeological investigation that brought to light the ruins of the baths of a mid-imperial era-built villa, whose stratigraphy dated the ultimate abandonment of the site to the end of the 5th century AD. Between 2014 and 2015 the excavation of the necropolis was carried out in an area that extends immediately north of the mouth of the river Fiumefreddo
Osservazioni preliminari sulla torre di Erbe Bianche di Misterbianco (Catania, Sicilia orientale)
No full textNell’ambito del progetto di inquadramento dei paesaggi fortificati di età greca nel territorio di Catania, è stata avviata una nuova indagine sulle costruzioni emerse fra il 1998 e il 1999 presso Misterbianco, in contrada Erbe Bianche. Tra esse, in particolare, vi sono i resti di una robusta struttura, posta a ridosso di un costone basaltico e identificata da M.G. Branciforti come una torre di avvistamento. La ricerca si pone come obiettivo di chiarire il rapporto evi- dente tra il sistema di fortificazioni che caratterizzò il territorio a partire dalla fine dell’età classica e la viabilità antica. La posizione della torre di Misterbianco nella media valle del Simeto è in chiara relazione con la via interna che da Catania si inoltrava verso Centuripe, della quale restano numerose testimonianze anche nelle fonti antiche. Attraverso il riesame dei dati a disposizione e di un rilievo fotogrammetrico, si vuole proporre una rilettura complessiva del monumento che riguardi tanto le caratteristiche costruttive quanto il ruolo nel quadro più ampio del sistema difensivo che si dispiega lungo i margini della Piana di Catania
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
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
