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

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
Effect of Biofertilizer on Population of Phosphate Solubilizing Bacteria under Green Onion Cropping
No full textABSTRACT
The plant cannot absorb phosphorus nutrient in the bound form but must be converted into an available form. Soil microbes have a role in the soil properties such as solubilized phosphor bound by acid secretion, and mineralization of organic phosphate components by converting into inorganic forms. Several types of microorganisms were identified. They can help the plants to provide the nutrients. Soil pH has a role in the availability of inorganic phosphorus. The aim of this study was to determine the effect of the addition of Bacillus aryabhattai to the population of phosphate solubilizing bacteria and soil pH. The research was conducted in the screen house and Integrated Laboratory of Indonesian Agricultural Environment Research Institute (IAERI) from December 2016 to March 2017. The experimental design was Completely Randomized Design with 4 treatment. The treatment involved Control (D1), Bacillus Aryabhattai (D2), Liquid Organic Fertilizer (D3), and Trichoderma (D4). The Pikovskaya medium was used to analyze the phosphate solubilizing bacteria. The results show that Bacillus Aryabhattai has a great influence on the increasing population of phosphate solubilizing bacteria. The population of phosphate solubilizing bacteria in the Bacillus Aryabhattai treatment was 3,1 x 107 cfu/ml, while in the control was 4,1 x 106 cfu/ml. There was found the similarities in trends between the number of phosphate solubilizing bacteria populations and soil pH. Bacillus Aryabhattai has a great potency to increase the plant nutrients especially phosphorus
