Analisi di provenienza di ceramiche dal sito di piazza Marconi a Cremona
No full textInformazioni sulla provenienza di reperti fittili possono essere ottenute indirettamente a partire dai dati sulla composizione elementare. Infatti la conoscenza della composizione chimica, con particolare attenzione a quelli cosiddetti minori o addirittura in tracce, è direttamente legata a quella della materia prima utilizzata.
Sono stati analizzati con la tecnica EDXRF in modo rigorosamente non distruttivo circa cinquanta frammenti ceramici (II sec. a.C.) provenienti dallo scavo di piazza Marconi a Cremona, oltre a campioni di riferimento provenienti da Adria, Volterrra, Arezzo e Cremona.
La determinazione della provenienza è stata effettuata con tecniche di analisi multivariata: in particolare, PCA e Cluster Analysis
Going Beyond Counting First Authors in Author Co-citation Analysis
Full text linkThe 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
A Review of the Indices of Mizaj-e-Meda (Temperament of Stomach) identification in Persian Medicine
Full text linkBACKGROUND AND OBJECTIVE: Digestive diseases are one of the problems of the health system in the world. From the perspective of Persian medicine, the stomach begins the second stage of digestion and its function plays an important role in human health or illness. The written sources of Persian medicine have been widely used to determine the health of the stomach. The purpose of this study is to summarize indices of Mizaj-e-Meda (Temperament of Stomach) identification to help better diagnose the status of health or illness of stomach.
METHODS: In this review article, 11 valid Iranian medicine sources and scientific databases of Scopus, PubMed, Science Direct, Google Scholar, Elsevier, and web of science as well as Persian indices of SID, Iran Doc, Magiran were searched and the existing views were summarized.
FINDINGS: In the sources of Persian medicine, the indices of different types of Mizaj (temperament) and Su-e-mizaj (abnormal temperament) have been proposed. Seventeen articles on the subject of gastric diseases in Persian medicine were found; one case merely examined gastric symptoms, while others only slightly referred to the indices. Some of the most important indices considered in these sources for identifying the type of Mizaj-e-Meda were the way of digestion, desire for food according to the type of Mizaj (temperament), thirst, appetite, burrow, moisture and taste of the mouth, tongue and mouth condition, flatulence, quality of waste matter, speed of food passage, sour stomach, burning stomach, stomach ache and stomach malmas (touch).
CONCLUTIONS: Persian medicine sources have fully cited gastric indices, which can be used for a more effective diagnose and treatment and even prevention of gastric diseases, and can also be used for designing and validating standard scales for Mizaj-e-Meda (Temperament of Stomach) identification
Variations on the Author
Full text link“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
Full text linkWe 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
Full text linkWe 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
