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
La collezione orientale del Museo Archeologico Nazionale di Firenze, Volume II. Anatolia, Mesopotamia, Iran, Siria,
No full textLa collezione orientale del Museo Archeologico Nazionale di Firenze, che comprende numerosi reperti provenienti dalla Turchia, dall’Iraq, dall’Iran e dalla Siria, databili tra la preistoria e il periodo medievale, costituisce una delle più importanti raccolte di oggetti provenienti dal Vicino Oriente conservate in Italia.I reperti che provengono dall’Anatolia, figurine antropomorfe e vasi, sono riconducibili alle culture del Calcolitico e del Bronzo Antico dell’area occidentale; le figurine antropomorfe e i vasi in stile Hacilar e Yortan rappresentano un gruppo di reperti di particolare interesse. Il lotto di materiali provenienti dalla Mesopotamia e dall’Iran comprende diversi oggetti: un rilievo neoassiro probabilmente proveniente da Ninive alcune decine di figurine in terracotta databili tra la fine del III e l’inizio del II millennio a.C., una testa di mazza votiva databile al periodo proto-dinastico, due pesi in pietra, tutti provenienti dal sud della Mesopotamia, alcuni reperti ceramici provenienti da Susa databili alla fine del V millennio a.C. e due lampade in bronzo ascrivibili al periodo islamico di produzione iranica.La collezione glittica include sia sigilli a stampo sia a cilindro, provenienti per lo più dalla Mesopotamia, che coprono un arco cronologico che va dal IV millennio a.C. al periodo sasanide (III-VII secolo a.C.) e con i suoi quasi 70 pezzi costituisce una delle maggiori raccolte di questi materiali presenti nel nostro paese
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
La collezione anatolica del Museo Archeologico Nazionale di Firenze
No full textThe book describes all Near Eastern materials arrived to the National Archaeological Museum of Florence through acquisitions and gifts and is composed by three sections devoted to different themes and geographical areas.
The Anatolian collection comprises findings in Hacilar and Yortan styles and pots of Western Anatolian origin acquired in the course of the 20th century and encompassing a large time span, from the Prehistory to the Early Bronze Age period.
The Mesopotamian collection includes different objects: a Neo-Assyrian relief, probably from Nineveh, several terracotta figurines dated back to the late third – early second millennium BC, a stone mace head, dated back to the Early Dynastic period and two stone weights. The Iranian collection includes some fragments and painted vessels from Susa, dated back to the late fifth millennium BC, and two Islamic bronze lamps.
Finally, the glyptic includes both cylinder and stamp seals, mostly from Mesopotamia, spanning from the fourth millennium BC down to the Sasanian period (III-VII centuries AD) and represents one of the most remarkable collection of this kind in Italy
La classificazione dei reperti e i contesti archeologici di riferimento
No full textIl lotto anatolico conservato presso il Museo Archeologico Nazionale di Firenze, per quanto eterogeneo nella sua composizione, è costituito da 45 manufatti che possono essere assegnati almeno a quattro gruppi principali meglio definiti quanto a decorazione, tipi, impasti, aspetto e trattamento della superficie: le statuette e le ceramiche dipinte di rosso su fondo chiaro; le ceramiche ingobbiate di rosso; le ceramiche grigio-scure; le ceramiche comuni. Tutti i manufatti provengono da siti che rientrano nell’orizzonte delle culture dell’Anatolia occidentale, di età compresa tra l’Età Calcolitica e l’Età del Bronzo Antico, fatta eccezione per una ciotola forse riconducibile alla fase finale del Neolitico: in generale, nel caso delle ceramiche e delle statuette dipinte di rosso e delle ceramiche grigie, l’area di possibile provenienza si restringe rispettivamente ai siti della cultura di Hacilar, nell’Anatolia sud-occidentale, e a quelli della cultura di Yortan, nell’Anatolia nord-occidentale; dei vasi ingobbiati di rosso e di uno in ceramica comune è difficile assegnare un’aerea di provenienza più circoscritta all’interno dell’Anatolia occidentale.

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
