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
Agroecologia e sistemi locali del cibo verso una convergenza? Dalla teoria alla proposta politica
No full textNegli ultimi due decenni gli approcci dell’agroecologia e dei sistemi locali del cibo hanno guadagnato importanza nel discorso scientifico suggerendo percorsi di trasformazione dei sistemi agricoli e alimentari alternativi al paradigma agroindustriale globale. I due paradigmi, pur avendo molti punti in comune, sono stati sviluppati separatamente e solo recentemente, stiamo assistendo al tentativo di trovare una convergenza. Gli obiettivi di questo
lavoro sono: analizzare la critica teorica al regime alimentare globale portato avanti dalla scuola agroecologica e da quella territorialista cercando di evidenziare gli elementi di differenza e complementarietà tra le due scuole; verificare l’operatività di tale convergenza all’interno del percorso di discussione delle strategie internazionali del cibo sviluppate a partire
dal controverso Food Systems Summit. Infine, il contributo avanza una proposta operativa di sperimentazione di quelli che potremmo chiamare i sistemi agroecologici del cibo locali.In the last two decades, the local food systems and the agroecology approaches have gained significance
in the scientific discourse, suggesting pathways to transform farming and food systems that are alternative to the global
agro-industrial paradigm. Despite sharing many commonalities, these two approaches have developed separately, and
just very recently some scholars attempted to bridge them into a single theoretical framework. The objectives of this
work are: to explore the theoretical critique of the global food regime developed by the agroecological and territorialist
schools identifying differences and complementarities to highlight the points of convergence and divergence between
the two schools; to explore to what extent the transformation pathways suggested by the two schools are discussed in the
political arena of the controversial Food Systems Summit. The paper suggests also an operative pathway for experimenting
the construction of local agroecological food systems
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
