Il generale dalla Chiesa, il terrorismo, la mafia
No full textIl 3 settembre 1982 a Palermo veniva ucciso dalla mafia il generale Carlo Alberto dalla Chiesa. Nella storia dell’Italia repubblicana, dalla Chiesa era l’uomo per gli incarichi difficili, fin da quando aveva scelto di andare volontario nella Sicilia di Salvatore Giuliano. Successivamente le istituzioni democratiche si affidarono a lui in alcuni dei momenti più drammatici, chiamandolo a contrastare l’offensiva del terrorismo brigatista, sia prima che dopo il sequestro e l’assassinio di Aldo Moro. La sua ultima missione, conclusasi con l’attentato che lo colpì assieme alla moglie, fu quella di prefetto di Palermo, dove era stato inviato a fronteggiare un’escalation di violenza della mafia senza precedenti. La sua carriera lo portò a vivere una molteplicità di situazioni, nel corso delle quali è stato dipinto come il più fedele dei servitori dello Stato, ma che, allo stesso tempo, lo hanno messo al centro di accuse e polemiche di varia natura. Finalmente la vita di uno degli uomini simbolo della nostra Repubblica viene ricostruita e raccontata da uno storico, grazie all’accesso a una documentazione vasta e inedita
Repressione antipartigiana al confine orientale:l'Ispettorato generale di pubblica sicurezza per la Venezia Giulia

No full textNon è vero, come vuole una idea diffusa, che la Sicilia non partecipò alla Resistenza. Ragioni storiche impedirono che nell'isola questa assumesse la forza, i caratteri, soprattutto la partecipazione che trovò al Centro-Nord, perché la Sicilia l'8 Settembre del '43 si era trovata già liberata dal nazifascismo. Ma essa non mancò di dare il suo contributo al grande evento alla base del futuro assetto civile, politico e costituzionale italian

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
