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
La ceramica dei livelli Uruk di Tell Hassan, Hamrin
Full text linkInternational audienceTell Hassan is one of the few sites in the Hamrin basin region in Iraq that hasshown remains of an Uruk period settlement along with Tell Rubeidheh and Tell al-Ahmad Hattu. The site was excavated by the archaeological mission of the Centro Ricerche Archeologiche e Scavi di Torino per il Medio Oriente e l’Asia in the late ‘70s. The investigations have unearthed at least three different Uruk levels but only the two most recent ones have been investigated on a limited surface. The ceramic assemblage provided by the excavation is made by a series of distinctive features that are attributed to the middle Uruk period. Numerous types considered as characteristic of the ceramic production of this period are reported including conical bowls, jars with thickened, rounded everted rim, jars with sharp-angled rim, jars with short, out-turned neck and flat rim and jars with out-turned neck and thickened, flattened rim, in addition to strap handles and tapering spouts. Moreover other types of characteristic middle Uruk decoration on jars are reported including incised parallel horizontal lines, curving cross-hatched comb decoration, bands of incised cross-hatching, rocker pattern, applied pellets and finger-impressed ribs. Comparisons with middle Uruk ceramic assemblage from sites of southern Mesopotamia as Uruk/Warka ‘Eanna-Tiefschnitt’ VIII-VI, Nippur ‘Inanna’ XX-XVII and Abu Salabikh ‘Uruk Mound’ confirm this dating. Other comparisons have been found with sites of northern Mesopotamia and the iranian Zagros as Sheikh Hassan 6-13, Nineveh ‘Uruk B’, Hacınebi B2 and Godin VI. The settlement may have been created as an outpost in a fertile region where no preexisting occupation existed at that time because no settlement dating after the end of the Ubaid period has been recorded in the area. Moreover the site, strategically located along the Great Khorasan Road, could have had a role in the control and exploitation of this major east-west trade route connecting the Mesopotamian lowlands with the Iranian plateau
Khirbet Hatara e gli orizzonti ceramici tardo calcolitici in Mesopotamia settentrionale
No full textThe excavations of Khirbet Hatara, carried out between 1985 and 1987 by the mission of Centro Ricerche Archeologiche e Scavi di Torino per il Medio Oriente e l'Asia, have shown some important levels dated to the Late Chalcolithic Period. The chrono-typological and comparative study of pottery assemblage and the re-examination of the excavation documentation made it possible to place some of these levels in the context of northern Mesopotamia of the first half of the 4th millennium BCE.The assemblage under consideration constitutes an important corpus that enriches the ceramic "panorama" of northern Iraq, and more generally of northern Mesopotamia, of the Late Chalcolithic period. The presence of numerous diagnostic types (e.g. WFPs, Proto-Ninivite 5 pottery, large deep bowls with double rim, jars and bowls painted, in particular with "drops" painted motif, hole-mouth jars with slightly raised edge and red or black burnished surface) made it possible to ascribe the earliest levels (2b-a) to the latest horizon of the Late Chalcolithic 2 (LC2) (i.e. "Gawra B" phase). The following levels (3b-a), marked by the presence of "Uruk grey" ware, but also of bowls with hammer-head and "casseroles" in their earliest variants and jars with internally grooved neck, fit rather to the assemblage of Late Chalcolithic 3 (LC3), perhaps to its earliest phase (i.e., horizon “Grey ware”), preceding the first contacts with "Uruk" southern Mesopotamia. As shown by numerous comparisons, the assemblage of Khirbet Hatara finds precise parallels both with Nineveh MM -59/-50 and MM -45/-39 and with Tepe Gawra X-IX and VIII, making it possible to complete the data of the sequences from both sites.La fouille du site de Khirbet Hatara, menée entre 1985 et 1987 par la mission du Centro ricerche archeologiche e scavi di Torino per il Medio Oriente e l'Asia, a mis au jour des importants niveaux du Chalcolithique tardif. L'étude chrono-typologique et comparative de la céramique découverte et l'examen de la documentation de fouille ont permis de situer certains de ces niveaux dans le contexte de la Mésopotamie du Nord de la première moitié du IVe millénaire av. J.-C.Le répertoire pris en considération constitue un important corpus qui enrichit le "panorama" céramique de l’Iraq du nord, et plus généralement de la Mésopotamie du nord, au Chalcolithique tardif. La présence de nombreux types diagnostiques (par exemple, WFPs, céramique Proto-Ninivite 5, grands bols profonds à double bord, jarres et bols peints, en particulier avec un motif en "gouttes", jarres hole‐mouth avec un bord légèrement surélevé et une surface polie rouge ou noire) a permis d'attribuer les niveaux les plus anciens (2b-a) à l'horizon plus récent (c'est-à-dire à la phase "Gawra B") du Chalcolithique tardif 2 (LC2). Les niveaux suivants (3b-a), marqués par la présence de la céramique "Uruk grey", mais aussi de bols hammer‐head et de "casseroles" dans leurs variantes les plus anciennes et de jarres à col intérieur rainuré, s’adaptent plutôt au répertoire du Chalcolithique tardif 3 (LC3), peut-être à sa phase la plus ancienne (c'est-à-dire à l’horizon "Grey Ware"), précédant les premiers contacts avec la Mésopotamie du Sud de culture "Uruk". Comme le montrent les nombreuses comparaisons, la céramique de Khirbet Hatara trouve des parallèles précis à la fois avec Ninive MM -59/-50 et MM -45/-39 et avec Tepe Gawra X-IX et VIII. Son répertoire céramique "complet" permet donc d'intégrer les données des séquences de ces deux derniers sites.Lo scavo del sito di Khirbet Hatara, effettuato tra il 1985 e il 1987 dalla missione del Centro ricerche archeologiche e scavi di Torino per il Medio Oriente e l'Asia, ha portato alla luce importanti livelli tardo calcolitici. Lo studio crono-tipologico e comparativo della ceramica e l'esame della documentazione di scavo hanno permesso di collocare alcuni di questi livelli nel contesto della Mesopotamia settentrionale della prima metà del IV millennio a.C.Il repertorio di Khirbet Hatara costituisce un importante corpus che arricchisce il "panorama" ceramico dell’Iraq settentrionale, e più in generale della Mesopotamia settentrionale, di periodo tardo calcolitico. La presenza di numerosi tipi diagnostici (e.g. WFPs, ceramica Proto‐Ninivite 5, grandi ciotole profonde con doppio bordo, ciotole e olle dipinte, in particolare con motivo dipinto a "gocce", olle hole‐mouth con bordo leggermente rilevato e superficie brunita di colore rosso o nero) ha permesso di assegnare i livelli più antichi (2b‐a) all’orizzonte "Gawra" della fase recente del Tardo Calcolitico 2 (LC2). I livelli successivi (3b‐a), contraddistinti dalla presenza di "Uruk grey" ware, ma anche di ciotole con bordo hammer‐head e "casseruole" nelle loro varianti più antiche e di olle con collo internamente scanalato, si adattano invece al repertorio del Tardo Calcolitico 3 (LC3), forse alla sua fase più antica (i.e, orizzonte Grey ware), precedente i primi contatti con la Mesopotamia meridionale "uruk". Come dimostrano i numerosi confronti, la ceramica di Khirbet Hatara trova precisi paralleli sia a Ninive MM ‐59/‐50 e MM ‐45/‐39 che a Tepe Gawra X‐IX e VIII. Il suo repertorio "completo" permette pertanto di integrare i dati delle sequenze di quest’ultimi siti, in parte falsate e incomplete a causa della parziale procedura di registrazione del materiale ceramico praticata all’epoca degli scavi
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
Phase I - Late Chalcolithic period
Full text linkInternational audienceThe Hirbemerdon Tepe Archaeological Project was initiated in 2003 as part of a broader cultural heritage rescue project associated with the construction of the Ilısu Dam and planned as part of a scientific collaboration between the University of Catania, the Istituto per l’Africa e l’Oriente and the Archaeological Museum of Dıyarbakir. The site is located on the western bank of the Tigris river about 100 km southeast of the modern city of Dıyarbakir. During the 10 years of archaeological work performed at the site 11 archaeological phases were recorded starting from the fourth millennium BC until the XIXth century AD
