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
Frontières et identités : étude des décors céramiques dans la région des monts Mandara et de ses plaines (Nord-Cameroun/Nord-Nigéria) à l'Âge du Fer
No full textDepuis au moins 500 ans, au sud du bassin du lac Tchad, la région des monts Mandara représente la rencontre géographique et culturelle entre deux mondes aux modes de pensée opposés : les
populations des montagnes, égalitaires et non-islamisées, et celles des plaines environnantes,
vivant sous le contrôle hiérarchique d’États islamiques, tels que Bornou et Wandala. Cette thèse
s’inscrit dans une longue tradition de recherches archéologiques et ethnologiques entreprises
depuis une quarantaine d’années dans cette région du monde afin de documenter le rapport
ambigu qui existe entre ces deux systèmes sociopolitiques, au passé et au présent. Entre 1993
et 2012, les équipes d’archéologues du Projet Maya Wandala (PMW) et du Projet DGB (Diygyd-
bay) ont mis sur pied l’une des plus grosses bases de données céramiques uniformisées de
la région.
Suivant une approche holistique, diachronique et régionale de la question des contacts culturels
en zone frontalière, cette étude porte sur le décor céramique de 150 000 tessons issus de ce
corpus. Provenant de huit sites clés du Nord-Cameroun et du Nord-Nigéria, ces petits objets
racontent plus de 3000 ans d’histoire de cette région, du Néolithique jusqu’à la fin de l’Âge
du Fer Final. Les méthodes d’analyses statistiques de classement (cluster analysis) par nuées
dynamiques (k-moyennes) et d’agrégation Ward ont été mises à profit afin d’explorer les
similarités et les différences de ces collections, à travers le temps et l’espace. Par la comparaison
de mes résultats avec les données archéologiques, ethnologiques et historiques de notre région
d’étude, une histoire chronologique de chacun des sites est proposée. Sur le site DGB-1/-2,
plus important témoin à ce jour de l’occupation préhistorique des montagnes, les lieux de vie
quotidienne, cooking area par exemple, se distinguent de ceux qui servent à l’aménagement
physique, entre autres les remblais, malgré la similitude des décors céramique qu’on y retrouve.
L’identification de quatre groupes aux décors céramiques particuliers met en exergue les
différences qui apparaissent entre les populations des plaines et des montagnes, ainsi qu’entre
les populations des plaines associées à l’élite étatique de Wandala, et les autres.
Dans le contexte de la mise en place des premiers États centralisateurs dans la région, nous
voyons donc comment ce phénomène historique d’importance a eu des répercussions non
seulement sur l’occupation et la perception du paysage, mais également sur l’identité céramique.For the last 500 years at least, in the southern area of Lake Tchad, the Mandara Mountains
region represents the geographical and cultural meeting point of two contrasting ways of
thinking: the egalitarian and non-Muslim populations of the mountains; and the populations
of the surrounding plains—dominated by the hierarchical authority of Islamic states, including
Bornou and Wandala states. This thesis is the continuation of a long tradition of archaeological
and ethnological research completed during the last 40 years in this region. Its aim is to document
the ambiguous relationship that exists between these two socio-political systems, in the past and
the present. Between 1993 and 2012, teams of archaeologists working on both the Projet Maya
Wandala (PMW) and the Projet DGB (Diy-gyd-bay) established one of the largest ceramic
databases in the region.
Following a holistic, diachronic and regional approach regarding the issue of cultural contacts
in the border area, the present thesis focuses on the analysis on ceramic decoration from this
dataset. These potsherds (n=150,000), originating from eight key archaeological sites located in
Northern Cameroon and Northern Nigeria, tell the story of the region spanning more than 3000
years, dating from the Neolithic to the end of the Late Iron Age (LIA). Methods of statistical
analysis, such as cluster analysis by dynamic clustering (K-Means) and Ward aggregation, have
been used in order to explore both similarities and differences present in these collections,
through time and space.
After a comparison of my results with the archaeological, ethnological and historical data of
the study area, a chronology of these sites is proposed based on the ceramic data. On the DGB-
1/-2 site, the most important evidence of prehistoric occupation of the mountains, the domestic
spaces, such as the cooking area, are differentiated from those used for redeposited materials,
despite the similarity of ceramic decorations found there. The identification of four groups of
distinct ceramic decorations underlines the differences that arise between the lowland populations
and those from the mountains, as well as between the lowland populations associated with the
Wandala elite, and other groups.
In the context of the emergence of the first centralised states in this region, we can see how this
important historical phenomenon had consequences, not only on occupation and the use of the
landscape, but also on ceramic identity
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

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.
