Full text link'Mio padre un falco, mia madre un pagliaio'. Famiglie di pastori, tra continuità e mutamento
No full textLa mistica del pastore solitario, disperso nella propria insondabile finitezza lungo i percorsi remoti della transumanza, si qualifica come uno dei contenuti più̀ evocativi delle rappresentazioni sociali sul mondo agro-pastorale sardo sedimentate nell’immaginario collettivo. Eppure, al di là della potenza simbolica associata a questa figura, eletta a perfetta metonimia dello squilibrio di scala tra Natura e Umanità, dal punto di vista empirico essa connota solo parzialmente la fisionomia relazionale degli attori sociali impegnati nel settore della pastorizia, oggi come ieri
Tra erbe e arbusti: la monocoltura ovina e la tenace resistenza del pastoralismo caprino in Sardegna
No full textIl saggio esplora la complessa relazione tra l'allevamento ovino e quello caprino in Sardegna, concentrandosi sulle differenze storiche, culturali e socio-economiche tra le due pratiche pastorali. Viene analizzata la storia della pastorizia caprina, dalle sue origini nel Neolitico fino ai giorni nostri, evidenziando il ruolo cruciale della capra nell'adattamento a diversi ambienti e climi. Si sottolinea come l'allevamento caprino, pur marginalizzato rispetto a quello ovino, abbia mantenuto un ruolo significativo in regioni difficili e povere. Il saggio affronta anche i pregiudizi storici verso la capra e i suoi allevatori, che vengono spesso associati a contesti di miseria e arretratezza, in contrasto con l'allevamento ovino, considerato più compatibile con lo sviluppo agricolo. Viene infine discusso l’impatto della modernizzazione e della razionalizzazione delle tecniche di allevamento, che hanno contribuito a trasformare profondamente la pastorizia tradizionale in SardegnaThe paper examines the complex relationship between sheep and goat farming in Sardinia, focusing on the historical, cultural and socio-economic differences between the two pastoral practices. The history of goat pastoralism is analysed from its origins in the Neolithic to the present day, highlighting the crucial role of the goat in adapting to different environments and climates. It highlights how goat farming, although marginalised in comparison to sheep farming, has maintained a significant role in difficult and poor regions. The paper also addresses historical prejudices against the goat and its breeders, which are often associated with poverty and backwardness, in contrast to sheep farming, which is considered more compatible with agricultural development. Finally, it discusses the impact of modernisation and rationalisation of breeding techniques, which have contributed to a profound transformation of traditional pastoralism in Sardini
Dinamiche evolutive nell’industria casearia tra Ottocento e primo Novecento. Modernizzazione e crisi dei sistemi tradizionali di produzione
No full textIl saggio ricostruisce le vicende dell'industria casearia in Sardegna dalla fine dell'Ottocento a metà Novecento, un'industria cresciuta potentemente intorno alla produzione di pecorino romano e in relazione alla richiesta crescente di questo prodotto caseario proveniente dagli Stati Uniti e dalle comunità italiane che vi erano emigrate. Lo sviluppo dell'industria del pecorino romano determinò altresì la crisi della produzione tradizionale sarda nella quale il pastore oltre ad essere un allevatore di ovini e anche il produttore del formaggio poi smerciato. L'inserimento della moderna industria casearia tolse al pastore sardo la gestione e il controllo della vendita del prodotto e provocò di fatto il suo impoverimento
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
