Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
We 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
Les populations amérindiennes de la vallée laurentienne, 1608-1765
The literature concerning colonial American populations has emphasized their dramatic decline as a result of the impact of European disease. The relative abundance of source material facilitates the observation of the evolution of native populations in the St. Lawrence valley. Following an initial series of epidemies in the 1630s, the population declined from about 500 to 200 individuals. This decline was compensated for by important migrations of Hurons in the 1650s and Iroquois and Abenakis thereafter. By 1675, the native population of the St. Lawrence valley surpassed that of the immediate precontact period. The population of the native villages close to French settlements stabilized around 2 500 people during the eighteenth century, and rose to over 4 000 in wartime with the influx of refugees. The results of this study underline the fact that native populations in a given territory could stabilize and even increase long after the arrival of Europeans and the importance of migrations to understand Indian population dynamics.L'historiographie de la dynamique démographique des populations américaines a beaucoup insisté sur leur chute dramatique suite au choc microbien. En raison de sources relativement abondantes, la vallée du Saint-Laurent constitue une aire privilégiée pour l'observation de l'évolution des populations autochtones. Suite à une première série d'épidémies dans les années 1630, les effectifs baissent d'environ 500 à environ 200 individus. Ces pertes sont compensées par des migrations importantes de Hurons dès les années 1650, et d'Iroquois et d'Abénakis par la suite, qui permettent de largement dépasser les effectifs initiaux. Au XVIIIe siècle, la population des villages auprès des défrichements français se stabilise autour de 2 500 individus et se gonfle jusqu'à plus de 4 000 en temps de guerre avec l'arrivée des réfugiés. Les résultats de cette enquête soulignent la capacité des populations amérindiennes à se maintenir et même à croître sur un territoire donné, longtemps après l'arrivée des Européens ainsi que l'importance des migrations dans la dynamique démographique autochtone.Dickinson John A., Grabowski Jan.
