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
Towards a "Global" Political Risk Analysis
No full textThe purpose of this paper is to test the relevance of the globalization variable for Political Risk Analysis (PRA). The concept of political risk and the analysis methodology adopted and used in PRA are extremely heterogeneous, varying profoundly case by case. However a common pattern can be identified. In almost every definition or operational concept of political risk, the focus relies almost entirely on the internal dimension. The models developed by both public and private agencies and institutions tend in fact to base their models on variables and indicators internal to the country object of the analysis. In those few cases in which the external variables are taken into consideration, they refer to classical events such as wars. In our opinion this approach is limited because it does not capture the structural processes generated by the global transformations of the last decades. In today’s globalized and ever changing world, we think that in any political risk analysis model it is fundamental to include a transnational perspective. A transnational variable should accordingly be crafted in order to complement the national variable by weighting the effects of the international and global dimension on local and national socio-political events. By testing out hypotheses with reference to two indexes related respectively to stability and governance, we find evidence of a positive relationship between the level of global integration of a country and its degree of stability and even more its level of governance. While these results (to be further tested with more sophisticated statistical tools in the follow up of the research) remain preliminary, they are sufficient to delineate a new understanding of political risk analysis that – by taking into consideration current concepts of political risk and modern theories of globalization – integrates in a comprehensive framework the more traditional variables of political risk with a new transnational variable
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
Musica e politica sulle ali del 'Rock’n’roll': migrazioni e contaminazioni
No full textL’ultima opera teatrale di Tom Stoppard, "Rock’n’roll", rappresentata per la prima volta a Londra nel giugno del 2006 e diretta da Trevor Nunn, sviluppa il concetto di migrazione su piani e assi diversi, spostandosi sincronicamente e in modo intermittente tra l’Inghilterra e la Cecoslovacchia (il protagonista è un ex emigrato ceco che torna al suo paese di origine, ma mantiene i suoi rapporti con Cambridge) e diacronicamente, dagli anni Sessanta ai Novanta. Centrale è il modo in cui l’autore rappresenta la trasformazione di un sogno generazionale, quello legato a valori e ideali appartenenti a una congerie storico-culturale unica quale quella del ’68, nel transito tra contesti geografici e sociali diversi e tra periodi storici diversi, trasferendosi quindi sul piano della memoria, e offrendo anche un interessante spunto di riflessione sul concetto stesso di ‘generazione’. Traendo ispirazione da alcuni scritti di Vaclav Havel, il drammaturgo fa però della musica il perno intorno al quale avvita il processo memoriale dell’opera. Negli anni Sessanta, interessati da una fondamentale convergenza delle arti e dei piani culturali alto/basso, nonché dal fiorire degli studi intorno alla nascente e subito proliferante pop culture, la musica pop e rock assume una posizione di assoluto protagonismo, facendosi portatrice di valori libertari e protestatari in un clima transnazionale di infuocata insofferenza verso ogni forma di gerarchia o istituzione. L’opera di Stoppard indugia quindi sulla fecondità della contaminazione tra musica e politica, musica e cultura, musica e vita nel veicolare quel ‘complessivo modo del sentire’ di una generazione, il cui transito è seguito per tappe musicali tra il ’68 e il ’90: tra la contestazione e la fine del conservatorismo di ‘ferro’, tra la Primavera di Praga e la Rivoluzione di velluto

No full textDispelling 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
Dalla community conservation ai peace parks: i nuovi paradigmi della tutela della natura in Africa australe
No full textA partire dagli anni novanta i concetti, le politiche e le pratiche della conservazione in Africa, soprattutto australe, sono state integrate e arricchite da una serie di proposte alternative che hanno determinato uno spostamento paradigmatico del pensiero sul modo più appropriato di gestire le risorse naturali e sulle relazioni che devono intercorrere tra governo centrale e locale. Queste nuove idee sono diventate così popolari e largamente accettate, da dare vita a una nuova ortodossia contrapposta all’approccio tradizionale della protezione statalizzata e centralizzata.
In Africa i confini politici ereditati dal colonialismo tagliano spesso gli ecosistemi naturali e dividono le comunità etniche. Con l'obiettivo di rimuovere queste barriere e di promuovere la conservazione della biodiversità e la collaborazione tra comunità vicine, è nata l'idea della creazione di grandi aree protette transfrontaliere grazie, soprattutto, all'attività della Peace Parks Foundation, una organizzazione non governativa istituita nel 1997 che si adopera per la realizzazione del “sogno pan-africano” di un’Africa senza confini o barriere
