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
Continuità discontinue. Tra topografia antica e archeologia del paesaggio / Discontinous Continuities. Between Ancient Topography and Landscape Archaeology
No full textThe contribution, through reference to selected texts by Umberto Moscatelli and Nereo Alfieri and starting from a preliminary discussion on the differences in approaches and research subjects between ancient topography and landscape archaeology, seeks to initiate a first reflection on a theme that archaeology tends to overlook: how to explain continuities and why doing so can be relevant both in research approaches and in the practical implications of our discipline.Il contributo, attraverso il riferimento ad alcuni testi di Umberto Moscatelli e di Nereo Alfieri e a partire da una preliminare discussione sulle differenze negli approcci e negli oggetti di ricerca della topografia antica e dell’archeologia del paesaggio, prova ad avviare una prima riflessione su un tema che l’archeologia tende a eludere: come spiegare le continuità e perché farlo può avere una rilevanza sia negli approcci di ricerca, sia nelle ricadute applicative della nostra disciplina.

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

Defensive systems and structures in Central Eastern Italy in Early Middle Ages: a preliminary approach based on documentary sources
No full textThe theme of the development of systems and defensive structures in Early Middle Ages and Middle Ages has never been appreciated by archaeologists in this side of Italy. Some recent scientific contributions pay more attention on history or on the walls building techniques. However, even if the lack of archaeological excavation makes it difficult the approach to this topic, a comparative analysis of documentary sources and material evidences in fortified contexts paves the way to some interesting remarks. The written sources of early Middle Ages provide a discontinuous patchwork mostly related to the events that accompanied the growth of ecclesiastical power (Abbeys and Roman Church). Sometimes we have only the factual reference to some fortification event, like in the case of the monks of the Farfa Abbey, when they fecerunt castellum to defend themselves against Saracen attacks. Sometimes, on the contrary, we find specific references to the building material of the fortification. The archaeological sources consist of earthworks or remains of castle (more or less ruined...), usually reflecting building projects dating back to the Late Middle Ages, but often put in the same places where the oldest defences had been raised. Based on those data, the author seeks to identify the tendencies in the topographical choices of the earliest fortifications, as well as in the technical solutions chosen
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
