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
Eriocaulon meenachilense Anoop & Robi 2021, sp. nov.
No full textEriocaulon meenachilense Anoop & Robi, sp. nov. Eriocaulon meenachilense resembles E. tuberiferum A.R.Kulk. & Desai in its root tubers, short, linear leaves and free female sepals. However, the new taxon differs in its solitary, 6-angled peduncle, short sheath, white inflorescences, inflexed involucral bracts, free male sepals, eglandular petals, yellow anthers and unappendaged yellow seeds. It also similar to Eriocaulon idukkianum Manudev, Robi & Nampy, another tuberous species from the Western Ghats that has linear leaves, white inflorescences, male flowers with free sepals and unappendaged seeds, but differs from that species in the absence of a root stock, its hairy, not glabrous root tubers, its solitary, 6-angled peduncle, and its glabrous receptacle, eglandular petals and yellow anthers and seeds . – Type: India, Kerala, Kottayam District, Meenachil, Illikkal Hills, c. 1000 m a.s.l., 7 x 2019, Anoop.

Eriocaulon meenachilense is known only from the type locality, the Illikkal Hills in the southern Western Ghats, India (Figure 3). Phenology. Flowering and fruiting from August to November. Etymology. The specific epithet refers to the type locality, Meenachil Taluk in Kottayam District, Kerala, India. Habitat and ecology. Wet rocky grasslands in association with Eriocaulon thwaitesii Körn., Exacum sessile L., Impatiens stolonifera Robi & Manudev, Phyllocephalum scabridum (DC.) K.Kirkman, Smithia bigemina Dalzell, etc. Conservation status. Eriocaulon meenachilense is endemic to the southern Western Ghats, India. The authors located 42 plants in four groups within an area of 200 m 2. More extensive field surveys are required to better understand the true extent of occurrence and area of occupancy of this species. According to IUCN criteria, the species falls under the category Data Deficient (IUCN, 2012; IUCN Standards and Petitions Subcommittee, 2019). Eriocaulon tuberiferum has so far been reported from the northern Western Ghats in Maharashtra State and southern Western Ghats in Kerala State (Sunil et al., 2018). The species is usually seen in the margins of puddles and open wet rocky slopes at 900–2100 m elevation. Eriocaulon idukkianum is confined to the southern Western Ghats in Kerala State and generally found at 2000–2300 m elevation in marshes near streams and rock crevices, in association with mosses. The major characters differentiating Eriocaulon meenachilense from the two other Indian tuberous species are listed in the Table.Published as part of Anoop, P. B. & Robi, A.

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
