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
Avaliação do desempenho de argamassas colantes em parede de concreto não lavada de acordo com a NBR 13754:1996 e a NBR 14081-3:2012
Get PDFIndustries linked to the civil segment are commonly interested in ceramic coatings and mortar production, since Brazil has presented in the last years high consumption of these products, in the face of such scenarioit is of interest to evaluate the quality and performance of commercial mortars for the installation of ceramic coatings. Thus, the quanti-qualitative study, which includes a case study as a survey, seeks to ascertain the quality and performance of the manufacturer 1’s commercial mortars (AC-I, AC-II and AC-III), from manufacturer 2 (AC-I, AC-II and AC-III) (AC-I, ACII, AC-III) for ceramic coating laying on un-washed concrete wall from NBR 13754:1996 and NBR 14081-3:2012 standards. In front of NBR 13754:1996 and NBR 14081-3:2012 it was possible to determine values of resistance to traction adhesion (NBR 13754:1996), assumption of open time (NBR 14081-3:2012), observations and inferences of the ways in which the uprootings and ruptures of the commercial adhesive mortars occurred.It was evaluated that the mortar that presented the most adhesion was the AC-II manufacturer 3 and the one that obtained the lowest adhesion was the AC-I of manufacturer 2, the observational requirements of grubbing inferred that all mortars were broken at the mortar/substrate interface in different proportions, ensuring that all the attraction resistance values were equal to those of the tests. The mortars of manufacturer 3 AC-I, manufacturer 2 AC-I and AC-II did not meet the open time limit required by the standard. However, it was found that the mortars that presented better performance and proved to be of higher quality for the settlements of ceramic coatings on a non-washed concrete wall, were the mortars manufacturer 1 AC-I and AC-II.Indústrias vinculadas ao segmento de civil encontram-se comumentemente interessadas em revestimentos cerâmicos e na produção de argamassas, pois o Brasil tem apresentado nos últimos anos alto consumo desses produtos, diante de tal cenário torna-se interesse avaliar a qualidade e desempenho de argamassas comerciais para o assentamento de revestimentos cerâmicos. Assim, o estudo quanti-qualitativo o qual engloba um estudo de caso como levantamento, busca averiguar a qualidade e o desempenho das argamassas comerciais do fabricante 1 (AC-I, AC-II e AC-III), do fabricante 2 (AC-I, AC-II e AC-III) do fabricante 3 (AC-I, ACII, AC-III) para o assentamento de revestimento cerâmico em parede de concreto não lavada a partir das normas NBR NBR 13754:1996 e NBR 14081-3:2012. Diante das normas NBR 13754:1996 e NBR 14081-3:2012 pôde-se determinar valores de resistência á aderência á tração (NBR 13754:1996), suposição do tempo de aberto (NBR 14081-3:2012), observações e inferências das maneiras como ocorreram os arrancamentos e as rupturas das argamassas colantes comerciais. Avaliou-se que a argamassa que apresentou mais aderência foi a AC-II fabricante 3 e a que obteve menor aderência foi a AC-I do fabricante 2, os quesitos observacionais de arrancamentos inferiram que todas as argamassas sofreram rupturas na interface argamassa/substrato em diferentes proporções, garantindo que todos os valores de resistência á atração foram iguais aos dos ensaios. As argamassas do fabricante 3 AC-I, fabricante 2 AC-I e AC-II não atenderam ao limite de tempo em aberto exigido pela norma. Contudo, verificou-se que as argamassas que apresentaram melhor desempenho e demonstraram-se de maior qualidade para os assentamentos de revestimentos cerâmicos em uma parede de concreta não lavada, foram as argamassas fabricante 1 AC-I e AC-II
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
