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
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
Mise au point d’itinéraires de culture économes en produits phytosanitaires en productions de pépinière hors sol
No full textLe projet HORTIPEPI avait pour objectif de mettre au point des itinéraires culturaux économes,
permettant de réduire de 50 % l’usage des produits phytosanitaires en pépinière hors-sol. De bons
résultats ont été obtenus concernant les insecticides. La lutte biologique a fait ses preuves dans les
dispositifs expérimentaux. Cette méthode de protection demande du temps d’observation des cultures,
un suivi des températures et une anticipation des commandes d’auxiliaires mais aussi d’imaginer
l’aménagement des surfaces autour des parcelles, voire des parcelles elles-mêmes. Concernant la
réduction des fongicides appliqués en protection des parties aériennes et racinaires, les résultats
mettent en évidence l’importance des conditions de cultures pour prévenir le développement des
maladies. Ce levier est trop souvent négligé alors qu’il impacte fortement la santé des cultures.
L’efficacité de certains micro-organismes contre les maladies fongiques racinaires semble variable
d’une année à l’autre, les conditions météorologiques jouant un rôle important. Enfin, même si
l’utilisation des herbicides a presque été supprimée grâce au paillage des conteneurs, la gestion des
abords de cultures reste problématique. Or, les infrastructures agroécologiques peuvent jouer un rôle
important concernant la protection des cultures, cette thématique sera travaillée dans les années à
venir.HORTIPEPI project goal is to reduce of 50% plant protection products in nursery soilless crops. Good
results have been obtained in the reduction of insecticides. Biological control has been proven in
experimental devices and can reduce and replace plant protection products. This method of protection
of crop needs observation, temperature monitoring and anticipation of auxiliary controls. With regard to
the reduction of fungicides applied to protect aerial and root parts, the results highlight the importance of
growing conditions to prevent fungi infestations. This lever sometimes neglected whereas it strongly
influences the health of crops. Efficacy of microorganisms against root fungal diseases, is variable from
one year to another, the weather plays an important role. Finally, even if the use of herbicides has
almost been eliminated in crops areas thanks to the use of mulches on containers, areas around
cultivated plots remain problematic to maintain. Those surfaces can nevertheless play an important role
concerning cultures protection, this subject must be worked in the years to com
