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
Initial acceptance trial of flavours in a standard concentrate diet in horses at pasture.
No full textPrevious trials have focused on stabled horses in assessing flavour acceptance. In this trial we aimed to investigate flavour acceptance by pastured horses. The hypothesis was that horses would vary in acceptance of diets based on their flavour.
Eight flavours used historically as flavourants were presented to eight horses maintained at pasture, at 1% in standard meals of 100 g cereal by-product. Diet acceptance, selection and consumption times were recorded. A Latin Square design was used to control for order effects. Before data collection, two meals of 100g of base diet (a standard cereal by-product) were offered, at the usual meal times, to approximate standard hunger levels.
For the trial, horses were brought into individual familiar stables. Meals were offered in door mounted mangers, each used exclusively for that flavour to avoid residual effects. A minimum of one hour separated the meals which were terminated following complete consumption or no further interest for two minutes. Times for either; Complete consumption; Partial rejection (food partly consumed but then ignored for 2 minutes) or Total rejection were recorded. Any diet remaining was reweighed.
Mean consumption times were compared using Kendall’s coefficient of concordance. Variation in amount consumed was compared for all eight flavours using Kendall’s coefficient of concordance. This showed a significant difference existed between amount consumed (W = 0.314, n = 8, p < 0.01). Mean time to consumption or rejection was affected by individual variation and were NS for the group overall. The most accepted flavour by weight consumed was Agrimony (mean rank 2.81). The least preferred flavour was Elecampagne (mean rank 6.56).
This trial showed flavour concentrations of 1% in a standard base diet significantly affected diet selection and acceptance, but not consumption times of pastured horses. These results may have practical implications in diet formulation for pastured horses
