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
Desarrollo de vacunas DIVA que confieran protección cruzada frente a distintos serotipos del virus de la peste equina africana
Get PDFTesis inédita de la Universidad Complutense de Madrid, Facultad de Ciencias Biológicas, leída el 13-05-2022El virus de la peste equina africana (AHSV) es un patógeno que afecta principalmente a equinos. Se trata de un arbovirus de la familia Reoviridae y del género Orbivirus transmitido por la mordedura de insectos infectados del género Culicoides.La enfermedad causada por este patógeno, la peste equina africana (AHS), es endémica en el África sub-sahariana, pero se han producido brotes ocasionalmente en el Norte de África, Oriente Medio, sur de Europa y recientemente en Tailandia en el año 2020. Factores como el cambio climático, el transporte internacional de animales, junto con la alta competencia vectorial demostrada por las especies de Culicoides y su distribución mundial, aumentan el riesgo de posibles brotes de AHSV en zonas libres de la enfermedad.La vacunación es la única estrategia efectiva para el control y la prevención de la peste equina africana. Sin embargo, las vacunas disponibles en la actualidad están basadas en virus atenuados, y aunque son relativamente eficaces, plantean problemas de seguridad por lo que está prohibido su uso en Europa. Debido a esto, diferentes grupos de investigación están trabajando en el desarrollo de vacunas de nueva generación basadas en proteínas recombinantes, partículas virales similares a virus (VLPs) y vectores virales recombinantes. Su objetivo es generar vacunas seguras, capaces de inducir una respuesta inmunitaria total y duradera en ausencia de adyuvantes, además de poder diferenciar serológicamente entre animales infectados y vacunados (DIVA)...African Horse Sickness virus (AHSV) is a pathogen which affects principally to equids. This is an arbovirus classified within the Reoviridae family and the Orbivirus genus, that is transmitted primarily by the bite of infected insects of Culicoides species.The disease caused by this pathogen, African Horse Sickness (AHS), is endemic to sub-Saharan Africa although it occasionally spreads into North Africa, the Middle East and Southern Europe. Several factors such as global climate change, international trade of animals, together with the high vector competence of Culicoides and its worldwide distribution, increase the risk of future outbreaks of the disease in AHSV free countries.Vaccination is the only effective strategy to control and prevent this disease. Nevertheless, the current available vaccines based on attenuated viruses are not always effective and pose a number of safety concerns. Therefore, their use has not been approved in Europe. For this reason, several laboratories are working on the development of new generation vaccines based on recombinant proteins, Virus-Like Particles (VLPs) and recombinant viral vectors. Their aim is to obtain safe vaccines capable to induce complete protection against AHSV and long-lasting immune responses without adjuvants. At the same time, the use of these vaccines would allow differentiate infected from vaccinated animals (DIVA)...Fac. de Ciencias BiológicasTRUEunpu
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
