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
Toti Scialoja e Pino Pascali: contrappunto
No full textIl contributo approfondisce il dialogo fra Toti Scialoja (1914-1998) e Pino Pascali (1935-1968) nato nella aule dell'accademia di Roma, dove Scialoja insegnava e Pascali si iscrive nel 1955-56. A questa altezza cronologica Pascali è poco più che ventenne e Scialoja è un pittore già noto e apprezzato sulla scena artistica internazionale, con la quale instaura rapporti diretti in occasione della sua mostra personale alla Cathrine Viviano Gallery di New York, rivelatasi fondamentale per condurre alla maturità la propria pittura.
La febbrile ricerca sulla materia pittorica di questi anni persuade i giovani allievi dell’accademia e, nello specifico, il giovane Pascali che, fin da subito, si confronta con tecniche e materiali inusuali, da cui derivano visioni inaspettate e cariche di vitalità.
Se per Scialoja i viaggi americani sono indispensabili per emancipare la propria ricerca, per Pascali gli Stati Uniti d’America restano un miraggio, restituito nella fascinazione per le ambientazioni urbane d’oltreoceano, i film dei gangster e soprattutto l’opera di Jasper Johns che ha modo di vedere alla Biennale di Venezia del 1964.
Alla luce della distanza generazionale e delle attitudini personali, il contributo restituisce il dialogo fra due artisti fra il 1955 e il 1964, evidenziando confluenze e differenze di temi, processi e immaginari
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
A case study of a digital twin for designing intermodal railways operations for a maritime terminal
No full textThe design of an intermodal transportation system, composed by road-rail-ship paths, usually passes through the capacity evaluation of the different stages, affected by means of transport features. Synchronicity of different stages and features of the utilities are a key factor in such infrastructure design. The simulation of a project, traditionally based on a static calculation of timetables for transportation connection guarantee, can be done actually with a Digital Twin approach for a whole dynamic simulation of the process. The paper deals with a real case study in which a full intermodal system for minerals transportation, located in a desert, has been fully simulated, with interesting results analysis the for project validation. The intermodal system in object includes a mine-to-terminal truck transportation, a terminal-to-seaport monorail train transportation and a highly automated system for bulk material conveying from seaport to ships
