Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
Effectiveness of sticky trap designs and colours in trapping alate whitefly, bemisia tabaci (gennadius) (hemiptera: aleyrodidae)
No full textA study to determine the effectiveness of sticky trap designs with different colours for trapping alate whitefly (WF), Bemisia tabaci (Gennadius) (Hemiptera: Aleyrodidae) was carried out at MARDI Station, Jalan Kebun, in Klang, Malaysia from September 2004 to August 2005. Trap designs (cylindrical, horizontal, and vertical), colours (yellow, blue, green, red, white and black) and time (sampling dates) gave significantly (P<0.05) different effectiveness of trapping the alate WF, as well as indication of its population abundance in the field.
Both vertical and cylindrical traps were the most effective traps as significantly (p<0.05) higher numbers of alate WF caught on these traps than on traps of other designs. Meanwhile, yellow was the most attractive colour to alate WF, regardless of the trap design as it had the highest number of alates caught compared to the other colours. Comparatively, the vertical yellow trap was the most attractive and efficient trap to use in monitoring WF
Insects of Tasik Chini with special emphasis on Ichneumonid wasps
No full textA preliminary study on selected insect communities of Tasik Chini was conducted from 27th May to 2nd June 2004 along three trails namely trail to Sg. Gumum, trail to Kampung Melai and trail to old tin mining area. A total of eight Malaise traps were installed along the trail to Sg. Gumum while sweeping net and 10 yellow pan traps per trail were used to sample insects along the other two trails. A total of 502 insect individuals consisting of eight orders and 46 families were successfully collected. Of these, the hymenopterans (ants and wasps) had the most number (298 individuals and 11 families) while the Blattaria was the least number (six individuals and two families). Of the hymenopterans, the ichneumonids had the most individuals collected (52) followed by evaniid (50) and vespid wasps (41). For the Coleopterans, Cleridae were the most collected (26) during this short study followed by Anthribidae (13). There were 62 of individuals Odonata consisting of 9 species identified
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
