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

Annual Meeting of the Italian Group of Structural Geology dedicated in memory of our colleagues: Angelo Di Grande and Mario Grasso. Short Note? Catania, February 26-29, 2008 [Riunione Annuale del Gruppo Italiano di Geologia Strutturale - dedicata al ricordo dei nostri colleghi Angelo Di Grande e Mario Grasso]
No full textLe note brevi, raccolte in questo primo volume della serie dei Rendiconti della Società on line dedicata ai convegni delle Sezioni SGI, riguardano le comunicazioni orali e i poster presentati durante la riunione scientifica del Gruppo Italiano di Geologia Strutturale «GIGS» (sezione della Società Geologica Italiana), svoltasi a Catania nei giorni 26-29 Febbraio 2008. Gli argomenti trattati negli oltre 50 contributi coprono i vari temi della Geologia Strutturale e riguardano principalmente la Tettonica delle catene perimediterranee, dalle Ellenici alle Dinaridi, e dalle Alpi, attraverso l’Appennino, fino al Maghreb. Molti lavori affrontano l’analisi strutturale, utilizzando metodologie innovative, sviluppate anche da giovani ricerca- tori italiani, e un approccio alla micro e meso-scala, che, integrato con altri dati, permette di quantizzare e modellizzare i meccanismi e i processi deformativi della litosfera. Nel- l’occasione del centenario del terremoto di Messina, particolare interesse è stato dedicato agli studi di tettonica attiva che in Italia vanta una lunga tradizione anche per i fondamentali risvolti sociali ed economici. Nei contributi presentati alla riunione, tale argomento è stato affrontato sia a scala regionale che attraverso l’analisi meso e microstrutturale.
Diversi contributi riguardano lo studio della tettonica di aree localizzate in differenti continenti (Asia, Americhe), a dimostrazione di una notevole partecipazione dei ricercatori del nostro Gruppo a progetti di ricerca Internazionali
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
