Alchemical Gold and the pursuit of the Mercurial Elixir: An analysis of two alchemical treatises from the Tibetan Buddhist Canon
Get PDFThis article focuses on the analysis of two Tibetan treatises on iatrochemistry, The Treatise on the Mercurial Elixir (Dngul chu grub pa’i bstan bcos) and the Compendium on the Transmutation into Gold (Gser ’gyur bstan bcos bsdus pa). These texts belong to the rasaśāstra genre that were translated from Sanskrit into Tibetan by Orgyenpa Rinchenpel (O rgyan pa Rin chen dpal, 1229/30–1309) and integrated into the Tibetan Buddhist Canon of the Tengyur (Bstan ’gyur). The treatises deal with the processing of mercury, which is indispensable to convert metals into gold (gser ’gyur) and to accomplish the ‘mercurial elixir’ (dngul chu’i bcud len). The texts start with the description of a ‘pink-coloured’ (dmar skya mdog) compound, which is described as the amalgam of ‘moonlight-exposed tin’ (gsha’ tshe zla ba phyogs), gold, and copper. According to the texts, mercury has to be ‘amalgamated’ (sbyor ba) with ‘minerals that devour its poisons’ (za byed khams) and with ‘eight metals that bind it’ (’ching khams brgyad); at the same time, mercury is cooked with ‘red substances’ (dmar sde tshan) and other herbal extracts, types of urine and salts, and reduced to ashes. Starting with an outline of the earliest Tibetan medical sources on mercury, I analyse the two treatises with regard to their entire materia alchemica and the respective purification methods aimed at ‘obtaining essences’ (snying stobs), which are then to be absorbed by mercury. I argue that the two thirteenth-century treatises were particularly significant in the process of consolidating pharmaceutical practices based on mercury and the merging of alchemical and medical knowledge in Tibet
Knowledge, Imagery, and the Treatment of Communicable Disease in the Vase of the Amṛta of Immortality: A Preliminary Analysis of a Nyingma Medical Corpus
No full textThis paper intends to historically and conceptually analyze selected pre-modern Tibetan sources, outlining the medical and religious descriptions of a hybrid class of diseases called nyenné (gnyan nad) and rimné (rims nad). Among these sources, this essay focuses primarily on the diagnostic and ritual sections of the Great Vase of the Amṛta of Immortality (’chi med bdud rtsi bum chen). This Nyingma “treasure text” (gter ma) is representative of the magic-alchemical tradition that became an integral constituent of scholastic medical literature in Tibet from the thirteenth century onwards. Drawing on the contents of the Vase of Amṛta, the paper aims at situating this medical-oriented text in the broader context of Tibetan medical and tantric literatures
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
