Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
From summer pasture to mountain village : an archaeozoological approach to the establishment of agro-pastoral communities in the Caucasus mountains (VI-II mill. B.C.)
No full textLe Caucase est une région montagneuse et volcanique traversée par deux hautes chaînes de montagnes. De nombreuses richesses naturelles se trouvent dans ces zones d'altitude, tant bien d'origine minérale (obsidienne, minerais) que végétale (pâturages). Si l'exploitation et l'établissement de campement dans ces milieux contraignants sont connus depuis le Paléolithique, l'introduction au Néolithique (au cours du VIIe mill. av. n. è.) de ruminants domestiques a bouleversé les modes de vie et les pratiques de subsistance, interrogeant dès lors les stratégies d'élevage et les mobilités pastorales. La pratique des transhumances est souvent mentionnée par les archéologues pour caractériser ces mobilités et les occupations montagneuses. Toutefois des analyses isotopiques réalisées sur des dents de caprinés et bovins néolithiques d'Azerbaïdjan et Arménie ne confirment pas leur existence. Il s'agirait d'une pratique mise en place plus tardivement, au Chalcolithique, mais qui n'est pas systématiquement observée au cours de l'Âge du Bronze. Parallèlement, les données archéologiques témoignent pour le Chalcolithique et l'Âge du Bronze Ancien, d'une expansion des territoires occupés, notamment verticalement, avec des sites d'altitude associées à des structures architecturales légères liées à des occupations saisonnières mais également des structures plus solides pouvant être interprétées comme des occupations plus permanentes.À partir de l'étude des restes osseux d'origine animale, de la cémentochronologie et de la biogéochimie isotopique (des carbonates - δ18O, δ13C, 87Sr/86Sr - et du collagène - δ13C, δ15N) provenant de quinze sites archéologiques de Géorgie datés du Chalcolithique, de l'Âge du Bronze Ancien et de l'Early Kurgan Period ont été questionnée les relations plaines - montagnes à travers les pratiques de subsistance, les saisons d'occupation des sites, les mobilités pastorales et les pratiques zootechniques.Les résultats ont montré que l'exploitation des caprinés et bovins étaient majoritaires durant toute la période chronologique de l'étude et que leur ratio ne semble pas lié à leur position altitudinale. Les produits d'élevage recherché étaient la viande et le lait et à moindre mesure, les toisons. En parallèle nous avons pu être mis en évidence un étalement plus long de la saison des naissances des ovins dès l'Âge du Bronze Ancien, peut-être lié au développement de la production des produits laitiers dans le sud du Caucase. Certains sites d'altitude ont montré une occupation hivernale malgré des contraintes pour la gestion des ruminants. Des pratiques d'affouragement avec des plantes récoltées localement ont pu être identifiées. L'analyse des mobilités ont montré un certain régionalisme et parfois des mobilités restreintes autour des sites d'habitat. En cas de ruminants mobiles, les résultats ont montré que d'une manière générale que les ruminants des sites de plaines et piémonts n'avaient pas tendance à être conduits dans des milieux plus en altitude. Pour les sites d'altitude des signaux non transhumants et transhumants ont été identifiés. Le signal type transhumant sur sites d'altitude questionne : les ruminants retrouvent-ils les plaines ou étaient-ils menés dans des prairies encore plus en altitude ? Il reste toutefois difficile d'identifier clairement une variabilité des pratiques d'élevage inter-espèces en raison de la composition des assemblages d'études mais également en raison de mobilités et alimentation intra-annuelles différentes.The southern Caucasus is a region mostly occupied by large mountain ranges. These high-altitude areas are rich in natural resources, both inorganic (obsidian, ores) and biological (pastures). Exploitation and the establishment of camps in these harsh environments have been known since the Pleistocene, but the introduction of domestic ruminants in the Neolithic (during the VIIth millennium BCE) radically changed lifestyles and subsistence practices, raising questions about farming strategies and pastoral mobility. The practice of transhumance is often mentioned by archaeologists to characterise these movements and the mountain occupations. However, isotope analyses carried out on Neolithic caprine and bovine teeth from Azerbaijan and Armenia do not confirm their existence. It appears that this practice was developed later, in the Chalcolithic period, but was not systematically observed during the Bronze Age. At the same time, archaeological data from the Chalcolithic and Early Bronze Age periods show an expansion of occupied territories, particularly vertically, with high altitude sites associated with light architectural structures linked to seasonal occupations, but also more solid structures that could be interpreted as more permanent occupations.Based on the study of animal bone remains, cementochronology and isotopic biogeochemistry (of carbonates - δ18O, δ13C, 87Sr/86Sr - and collagen - δ13C, δ15N) from fifteen archaeological sites in Georgia dated to the Chalcolithic, the Early Bronze Age and the Early Kurgan Period, we examined the relationship between plains and mountains through subsistence practices, seasons of occupation of sites, pastoral mobility and zootechnical practices.The results showed that caprine and bovine livestock were in the majority throughout the chronological period of the study and that their ratio did not seem to be linked to their altitudinal position. The livestock products sought were meat and milk and, to a lesser extent, fleeces. At the same time, we were able to identify a longer staggering of the sheep-birth season from the Early Bronze Age onwards, perhaps linked to the development of dairy production in the southern Caucasus. Some high-altitude sites showed winter occupation despite constraints on ruminant management. Feeding practices using locally harvested plants were identified. The analysis of mobility showed a certain regionalism and sometimes restricted mobility around the habitat sites. In the case of mobile ruminants, the results showed that, generally speaking, ruminants at lowland and piedmont sites did not tend to be driven to higher altitude environments. For high altitude sites, non-transhumant and transhumant signals were identified. The typical transhumant signal at high altitude sites raises questions: did the ruminants return to the plains or were they driven to pasture at even higher altitudes? Finally, it remains difficult to clearly identify variability in inter-species breeding practices due to the composition of the assemblages studied, but also due to different intra-annual mobility and diet
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe 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

Author Under Sail The Imagination of Jack London, 1893-1902
No full textIn Author Under Sail, Jay Williams offers the first complete literary biography of Jack London as a professional writer engaged in the labor of writing. It examines the authorial imagination in London's work, the use of imagination in both his fiction and nonfiction, and the ways he defined imagination in the creative process in his business dealings with his publishers, editors, and agents. In this first volume of a two-volume biography, Williams traverses the years 1893 to 1902, from London's "Story of a Typhoon" to The People of the Abyss. The Jack London who emerges in the pages of Author Under Sail is a writer whose partnership with publishers, most notably his productive alliance with George Brett of Macmillan, was one of the most formative in American literary history. London pioneered many author models during the heyday of realism and naturalism, blurring the boundaries of these popular genres by focusing on absorption and theatricality and the representation of the seen and unseen. London created an impassioned, sincere, and extremely personal realism unlike that of other American writers of the time. Author Under Sail is a literary tour de force that reveals the full range of London as writer, creative citizen, and entrepreneur at the same time it sheds light on the maverick side of machine-age literature.Intro -- Title Page -- Copyright Page -- Dedication -- Contents -- Acknowledgments -- Introduction -- 1.
