Tomaso Casoni (1880-1933): A Pioneer Remembered
Get PDFTomaso Casoni (Figure 1A &1B) earned his fame by the test named after him [1]. Casoni was first to describe a test for immediate allergic reaction to hydatid fluid injected into the skin (Figure 2). This was in a time when hydatid disease caused by infection by Echinococcus granlulosus was endemic in Europe, Africa and the Middle East in addition to many other parts of the world. Therefore such finding was of great clinical significance at that time. However, as the skin test was increasingly replaced by other serological diagnostic methodology [2], the credit to Casoni has been fading away from the memory of medical and scientific community except for a few old Italian monographs [3-5]. There is a paucity of information on his life and works in the English literature even in the specialized web pages dedicated to history of science and medicine. A search using “Tomaso Casoni” as the search term on the internet’s two most commonly used search engines (Yahoo and Google) failed to find any substantial material. Thirty years ago, I was amongst a group of junior medical students in Tripoli, Libya. We learned for the first time about Casoni and his test from a small print foot note in “Bailey and Love’s Short Practice of Surgery”. We were so pleased that such a major textbook mentioned the institution where we were studying though its name changed to “Tripoli Central Hospital” following the independence of Libya. This event stimulated the interest of many in the history of science and medicine
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
Care for People with Diabetes during The Moslem Pilgrimage (Haj): An Overview
No full textIntroductionHaj is one of the five cardinal components of Islam commonly known as the five pillars of Islam. Approximately two million Muslims perform it each year. Haj involves travel to the holy sites in and around Mecca and Medina during a specified short period of time in a limited space, not usually inhabited by such a large number of people. This article deals with the effects of this event on diabetes and its management. The importance of this arises from the fact during Haj, the person’s life routine changes as he travels to a different place of his own for a period of 4–6 weeks where geography, weather, diet, and habits are different. During Haj most people live what is effectively a very basic life in very crowded places. Therefore, medical conditions, such as diabetes, whose management depends on a stable routine, would predictably be affected significantly
