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
Le commerce extérieur de l'U.R.S.S. au cours des années quatre-vingt : évolution et perspectives de développement
No full textMario Colucci. — The USSR's external trade during the 1980's : evolution and prospects for development.
This article brings out the fact that the rate of growth in Soviet foreign trade slowed down very considerably during the 1980's, falling slightly below the rate for the net national income. An analysis of the development of the sectoral structure of Soviet foreign trade bears out the view that the deceleration, compared with the two preceding decades, was the result of the country's inability to export anything other than non-food raw materials, of which the supply obviously tends to dry up. Consequently hopes of a rapide expansion in the USSR's foreign trade may well be disappointed, if current economic reforms do not succeed in effecting a sufficient transformation in the Soviet production system for it to become an exporter of finished products at a rate which will enable it amply to offset the tendency for exports of raw materials to diminish.
For the moment, it is stated that the results of the first two years of perestroïka (1986-1987) in terms of the expansion of foreign trade are disappointing. It is true that enterprise reform only came into force in 1988. However, without a real price reform and the creation of a true market for inter-industrial exchanges, it is doubtful how effective it will be. Finally, the steps taken to establish direct links between Soviet enterprises and foreign markets are held to be less than satisfactory. To sum up, much scepticism is expressed about the prospects for a spectacular growth in the Soviet Union's foreign trade, at least in the short and middle term.Mario Colucci. — Le commerce extérieur de l'U.R.S.S. au cours des années quatre-vingt : évolution et perspectives de développement.
L'article fait ressortir que le rythme d'expansion du commerce extérieur soviétique s'est fortement ralenti au cours des années 1980 devenant légèrement inférieur à celui du revenu national net. L'examen de l'évolution de la structure sectorielle du commerce extérieur de l'U.R.S.S. confirme la thèse que le ralentissement par rapport aux deux décennies précédentes est dû à l'incapacité de ce pays à exporter autre chose que des matières premières non alimentaires dont l'abondance tend évidemment à s'épuiser. Il en résulte que les espoirs d'un développement rapide des échanges extérieurs de l'U.R.S.S. risquent d'être déçus si les réformes économiques en cours ne parviennent pas à transformer suffisamment le système productif soviétique pour qu'il puisse devenir exportateur de produits finis à des rythmes permettant de compenser largement la baisse tendantielle des exportations de matières premières.
On constate pour l'instant que le bilan des deux premières années de perestroïka (1986-1987) est décevant en ce qui concerne l'expansion du commerce extérieur. II est vrai que la réforme de l'entreprise n'est entrée en vigueur qu'en 1988. Mais sans une réforme réelle des prix et sans la création d'un véritable marché des échanges interindustriels, on peut douter de son efficacité. On juge enfin peu satisfaisantes les mesures tendant à établir des liens directs entre les entreprises soviétiques et les marchés extérieurs. En conclusion, on se déclare très sceptique quant à la possibilité de développements spectaculaires du commerce extérieur de l'U.R.S.S., du moins à court et moyen termes.Colucci Mario. Le commerce extérieur de l'U.R.S.S. au cours des années quatre-vingt : évolution et perspectives de développement. In: Revue d'études comparatives Est-Ouest, vol. 20, 1989, n°1. pp. 43-53
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
