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
Density of Meretrix meretrix Clamps Under Ecological Pressure on Different Substrate Texture at the Kambu River of Kendari Bay, Southeast Sulawesi
Get PDFWhite clams at the mouth of the Kambu River in Kendari Bay have a preference for different substrate textures and are under ecological pressure. This study aims to determine the density of tofu shells at the mouth of the Kambu River, Kendari Bay, Southeast Sulawesi. This research was conducted at the estuary of the Wanggu River, Kendari Bay, Southeast Sulawesi from August 2021 to January 2022. White clams were taken manually using a 1x1 m squared transect. These shellfish samples were taken 6 times in repetition/station in each month of observation. Samples found in the field were counted. Taking the texture of the aquatic substrate together with the sampling of shellfish. The results showed that the maximum density of white clams at the mouth of the Kambu River, Kendari Bay, was 7.3 ind/m2. The highest density of white clams was found at stations I and II, while the lowest density was found at station III. The highest density of shellfish was found in the type of substrate which was dominated by the fine sand fraction, while the lowest density was found in the type of substrate which was dominated by the silt fraction
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
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
Ecological Index of Freshwater Gastropod in Buton Island, Southeast Sulawesi
Get PDFThis research was conducted for 2 months (September-October 2021) and is located on Buton Island. The purpose of this study was to determine the diversity of freshwater gastropod species on Buton Island. Determination of the location for sampling gastropods using purposive sampling method (qualitative) and quantitative sampling using simple random sampling technique at locations that have been determined based on the presence of gastropods. Gastropod samples were collected manually (hand picking) using a paralone pipe (3.5 inches), Sieve (1 mm), and Gloves. The total number of gastropods obtained at 31 sampling locations on Buton Island was 4250. Buton Island gastropods consist of 24 genera and 55 species spread over 10 families, namely Achantinidae, Ampullariidae, Ariophantidae, Cyclophoridae, Lymnaeidae, Neritidae, Pachychilidae, Planorbidae, Thiaridae, and Viviparidae. The average abundance of gastropods reached 137,097 ind./m2 and the abundance of gastropod species ranged from 0.28-25 ind./m2. Overall, the results of the gastropod ecological index analysis showed a stable condition, where the diversity of gastropod species was categorized as high (H' = 3.31), moderate evenness (E = 0.83), high species richness (R = 6.46), dominance showed that there were no dominant species (C = 0.03) and the distribution of gastropods showed a clumped pattern (Ip = 0.02). The majority of Buton Island gastropod communities occupy rocky rivers and currents, a few of them live in artificial inland waters such as rice fields, embankments, dams/dams, and drainages and some are terrestrial snails
