Pietro Blaserna and the birth of the Institute of Physics in Rome: a gentleman scientist at Via Panisperna
No full textThis book draws upon a wealth of archival material to present the life and achievements of Pietro Blaserna, a “gentleman scientist” whose greatest legacy is considered to be the Institute of Physics on the Via Panisperna in Rome, of which he was the creator and first director. Both in this role and as President of the Accademia dei Lincei, Blaserna contributed enormously in establishing a sound institutional base for the further development of physics in Italy. Starting from an accurate historical reconstruction of the scientific, social, and political context, the author presents the different phases of Pietro Blaserna’s life and career. As a multifaceted intellectual and a scientist holding several institutional positions, Blaserna worked ceaselessly to promote an effective policy in science and technology, which was critically important in stimulating the development of Italy as a modern nation. Blaserna may not have left scientific works that made history, but what he created in Rome was a real "house of physics", equipped with modern laboratories and instruments. In tracing his important legacy, this book will be of interest for all historians of science and for historians of nineteenth and twentieth century Italy
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
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

No full textTra politica e medicina: il no di Bartolo Nigrisoli - Between Politics and Medicine: the Refusal of fascism oath by Bartolo Nigrisoli
No full textBartolo Nigrisoli was a skilled surgeon as well as an excellent clinician. He was not only a very good teacher but also a mentor. He successfully completed thousands of surgeries and excelled in war surgery. He was driven by the idea that the physician was invested with a special mission that he always accompanied with a deep ethical and civil commitment. We can understand his decision in 1931 not to swear allegiance to the fascist regime, thus facing threats, dangers and persecutions because of his morality, his values as a citizen and contemporary as a physician, and the absolute belief in his own civil and cultural ideals. Besides, on the one hand, he was son of the Risorgimento while on the other, of a secular and positive philosophy. In conclusion, that gesture fully reflects all the man's composure and solidity, which he will then pour into the profession, both as a surgeon and as a teacher
