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
The impact of banking governance on risk taking and banking performance: Case of listed banks in the Mena region "During the COVID 19 health crisis"
No full textAfter treating the subject between the 2015-2019 financial year, we are supposed to test the same hypotheses published in the previous article during COVID Crisis. This article aims to measure the impact of banking governance on risk taking and bank performance, particularly during the COVID19 period, by working on the same sample. The data for the Y-2020 was extracted from S&P Capital IQ. A comparison between the results obtained in 2019 vs 2020 are based on the same assumptions. We conclude that the presence of the Sovereign Wealth Fund ownership, women on board committee, independent administrators has a positive impact on the performance of banks in the region, with some changes reported in detail.
The article presents a detailed study describing the impact of governance mechanisms before and during Covid crisis
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
Biodégradation de l'Ethyl tert-Butyl Ether et stimulation de la croissance bactérienne par des co-substrats
No full textL'Ethyl tert-Butyl Ether est ajouté aux carburants pour remplacer le plomb. A cause d'une utilisation intensive et de ses caractéristiques physico-chimiques, l'ETBE peut être une cause de pollution de l'environnement. La dégradation aérobie est connue, mais il en résulte un faible rendement cellulaire et un faible taux de croissance. L'objectif est d'augmenter cette croissance en maintenant la capacité à dégrader l'ETBE. D'abord, nous avons utilisé deux bioréacteurs aérobies à lit fixe en ajoutant de l'ETBE en phase gaz, à co-courant d'une aération directe pour le premier réacteur, et de l'ETBE dans la phase liquide, avec une aération indirecte externe pour le second. L'ETBE est dégradé dans les deux cas avec une augmentation de 70% de la croissance bactérienne dans le premier réacteur. En second,l'ETBE est en présence de diverses sources de carbone. La croissance est 3 fois plus importante en présence d'éthanol (1,728d-1) qu'avec de l'ETBE seul (0,504d-1), tout en dégradant l'ETBE.Ethyl tert-Butyl Ether is added to fuel to replace lead. Due to ils extensive use and ils physicochemical characteristics, ETBE can cause an environmental pollution. The aerobic degradation is known, but it results low cell yields and slow growth rates. The objective is to enhance this bacterial growth while maintaining the capacity to degrade ETBE. First, we used two aerobic lab-scale fixed bed reactors with ETBE addition in a gas phase and a direct aeration for the first bioreactor, and ETBE addition in the liquid phase with an indirect external aeration for the second one. ETBE is degraded in both bioreactors with 70% of enhancement of bacterial growth in the first one. Secondly, ETBE was degraded in batch culture in the presence of diverse carbon sources. The bacterial growth of ETBEdegrading consortia was enhanced 3 times more with addition of ethanol (l.728d-1) than with ETBE alone (0.504d-1), while maintaining ils ability to degrade ETBE.COMPIEGNE-BU (601592101) / SudocSudocFranceF
