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
Synthesis of reduced graphene oxide-silver nanohybrids: using monosaccharides as reducing agents at different time reaction / Faizatun Nabilah Nor Ismail
Get PDFSilver nanoparticles (AgNPs) were incorporated on the rGO sheets to create a reduced graphene oxide-silver (rGO-Ag) nanohybrid. This nanohybrid was created to improve the electrical conductivity of both materials, implying that it has several uses in diverse fields. This study demonstrated a simple synthesis of Reduced Graphene Oxide Silver (rGO-Ag) nanohybrids employing different monosaccharides (Galactose, Ribose, and Fructose) as reducing agents and at various reaction times (4h, 8h, 16h, and 24h). Ultraviolet-visible (UV-vis) Spectroscopy, X-Ray Diffraction (XRD), High Resolution Transmission Electron Microscopy (HR TEM), and Raman Spectroscopy were used to confirm the morphological and structural properties of the rGO-Ag nanohybrid. According to the UV-Vis analysis, galactose was the most efficient reducing agent. The largest peak detected by the rGO-Ag reduced with galactose [rGO-Ag (Gal)] at 271 nm corresponded to the creation of silver nanoparticles (AgNPs) on the rGO, while the narrowest peak observed at 423 nm belonged to the formation of silver nanoparticles (AgNPs) on the rGO. Attributing to the XRD inquiry, rGO-Ag (Gal) showing the amorphous crystallinity at peak 24.5° proving the succession of rGO convesion and recorded the smallest particle size 6.50 nm of AgNPs anchor on the rGO sheets. by using FWHM value obtained. was used to analyse the nanohybrids obtained with the other reducing agents. The samples' oxygen and carbon contents were also determined using a FESEM fitted with an energy-dispersive X-ray (EDX). In comparison to the other two monosaccharides, the average particle size determined from the rGO-Ag (Gal) XRD data was the smallest (6 nm). Furthermore, the rGO-Ag (Gal) d-spacing was nearly equal to the XRD data, corroborating the high-resolution transmission electron microscopy (HRTEM) findings. As a result, galactose was the perfect reducing agent for the production of rGO-ag nanohybrids. This research was then carried on by characterisation of nanohybrid at different time reactions using galactose as a reducing agent. On the UV-Vis study, the rGO-Ag (16h) showed the best result due to its intense peak of creation monodispersed spherical silver nanoparticles onto the rGO sheets. The predicted crystallite size of rGO-Ag (16h) in XRD analysis was the smallest 11.83 nm, which was also verified by HR TEM pictures of rGO-Ag (16h) and the histogram displayed confirming the particles size of monodispersed silver nanoparticles was 11 nm. According to the raman analysis, the ratio of D band to G band of the rGO-Ag nanohybrid was the highest, indicating the formation of the smallest crystallite size. The study went on to investigate the electrical behaviour of the nanohybrid using a twopoint probe. The I-V curve was plotted based on this data analysis, and rGO-Ag (16h) had the lowest resistance value of 68.82 Ω and the maximum conductance value of 14.52 10-3 sm-1. As a result, rGO-Ag, which was synthesised using galactose as a reducing and stabilising agent and at an ideal 16h reaction time, demonstrated the best electrical conductivity qualities, making it suitable for use in any electrical device
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
