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
I resti di cane provenienti dal Complesso Monumentale della Civita di Tarquinia (VT): considerazioni sulle ossa con tracce di macellazione.
No full textThe “Monumental Complex” located on the plateau of the Civita at Tarquinia (VT, Italy), is an important Etruscan site dated between the10th and the 2nd centuries BC. Excavations (1989-2011 years) were carried directed by M. Bonghi Jovino and G. Bagnasco Gianni who teachEtruscology at the University of Milan. The aim of this study is to analyse some cut marks recorded that were identified on the dog bonesfound in areas G, H, HM, L, M, O. These are added to the results of the animal remain study carried out by C. Sorrentino in 1986 and by E.Bedini in 1997, in order to better understand the role of dog in Etruscan ritual practices, as food source, and as raw material for the produc-tion of bone tools. The results are also compared with those from other Etruscan sites in which dog in present in burials or in ritual context
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
Analisi tecnologica e funzionale delle spatole realizzate su frammenti di costa di grande ungulato durante l'età del Bronzo nel Veneto sud-occidentale
Full text linkItTra le numerose categorie tipologiche di manufatti presenti in Italia settentrionale durante l'età del Bronzo, quella delle spatole su osso è certamente una delle più frequenti e numerose, specialmente nel territorio terramaricolo. Nel corso dello studio delle industrie su materia dura animale provenienti da siti dell'età del Bronzo del Veneto occidentale e meridionale, sono stati identificati alcuni strumenti a tranciante realizzati su costa di grande ungulato che, per morfologia e dimensioni, rientrano pienamente nella categoria tipologica delle spatole. Questi strumenti trovano confronti diretti con quelli identificati negli insediamenti dell'area benacense durante il Bronzo antico e medio e con quelli terramaricoli localizzati nella Pianura Padana a sud del Po. L'assenza di studi funzionali specifici non ha mai permesso una corretta identificazione della funzione e dell'impiego di questi oggetti nell'economia degli abitati. Gli obiettivi di questo lavoro sono quelli di contribuire ad identificare la funzione di questi oggetti attraverso uno studio sperimentale. L'analisi sperimentale, in una prima fase, è stata finalizzata a individuare la catena operativa di confezionamento in base allo studio delle tracce di lavorazione presenti sulle superfici degli strumenti. Nella seconda fase, sono state analizzate le usure presenti sul margine attivo delle spatole, confrontandole con quelle rinvenute sugli strumenti riprodotti sperimentalmente ed impiegati su diverse tipologie di materiale. Lo studio funzionale ha evidenziato una certa eterogeneità nelle tracce identificate sulle spatole analizzate, confermando l'impiego di alcuni dei manufatti archeologici nella lavorazione dell'argilla.EnAmong several typological categories of bone artefacts dated to the Bronze Age and recovered in north-eastern Italy , bone spatulas are certainly one of the most frequent and numerous, particularly in the area of Terramare. The analysis of animal bone tools found in the Bronze Age sites of south-western Veneto allowed identifying some bone tools with a cutting edge made by large ungulate rib fragments. Their morphology and size suggest including them in the typological category of the so-called spatula tools. This kind of artefacts can be directly comparable to those identified in the settlements located on the southern side of Garda Lake and in the area of Terramare. No use-wear analysis and experimental studies have been carried out until now; for this reason a right interpretation of their function is still unknown. This paper aims at identifying the function and the use of these tools throughout an experimental study. The analysis has been divided into two main phases: 1- to identify the chaîne operatoire; 2- to analyse the use-wear on spatulas surfaces by comparing the experimental traces identified on the tools that were reproduced and used on different types of material. The use-wear analysis showed various features on the distal edge of tools, confirming the use of several archaeological artefacts in clay processing
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
