Zarnab, une drogue énigmatique de la pharmacopée arabo-islamique : proposition d’élucidation
Get PDFZarnab, an enigmatic drug of arabo-islamic pharmacopoeia : proposition of elucidation.
By basing our work on analysis of the zarnab’s descriptions find in arabo-islamic medical writings of various periods and by comparing them with the floristic, ethnobotanic, phytochemical and linguistic data that we managed to collect following an important bibliographical compilation concerning a territory which extends from the Middle East to China, we tried to clarify the enigmatic nature of this simple aromatic for which all the identities which were proposed up to there were considered as not satisfactory.
This comparative study, realized in closer of the ancient texts and the acquired knowledge today on plants, their compositions, their vernacular names and their uses, allowed us to express propositions of elucidation of the identity of the zarnab, in agreement with the various interpretations given by the ancient authors, an identity which declines differently according to the space and the period considered. This differentiation of the zarnab in several products was made according to a logic that we tried to understand and that we explain.Basándonos en el análisis de las descripciones relativas al zarnab recogidas en escritos árabo-islámicos de diferentes épocas y comparándolos con los datos florísticos, etnobotánicos, fitoquímicos y lingüísticos que hemos reunido tras una importante compilación bibliográfica referida a un territorio que se extiende desde el Oriente Medio hasta la China, hemos tratado de esclarecer la naturaleza enigmática de este simple aromático para el cual las identificaciones propuestas hasta ahora no han resultado convincentes.
Este examen comparativo llevado a cabo lo más ceñido posible a los textos antiguos y los conocimientos hasta hoy adquiridos sobre las plantas, sus composiciones, sus fitónimos y sus empleos, nos ha permitido brindar unas propuestas de elucidación de la identidad del zarnab de acuerdo con las diferentes interpretaciones que los autores antiguos noshan ido dando, una identidad que se enuncia de manera diferente según la consideración del espacio y el tiempo. Esta diversificación del zarnab en varios productos se ha producido según una lógica cuyo funcionamiento hemos tratado de comprender y aquí explicamos

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
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
