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
Note sulla consistenza numerica e sui redditi dei mandriani delle valli bergamasche tra Ottocento e Novecento
No full textIl brano fornisce un quadro delle transumanze praticate nella prima metà dell’Ottocento tra le valli alpine della Lombardia centro-orientale e la pianura irrigua. Attraverso un manoscritto di Luigi Cattaneo, si descrive il ruolo sociale ed economico dei bergamini, allevatori transumanti provenienti da valli come la Valsassina, la val Taleggio, la val Brembana e la val Seriana.
Questi medi e ricchi imprenditori agricoli, pur vivendo in montagna e possedendo case, prati e pascoli, tra fine primavera e autunno si trasferivano in pianura con le loro mandrie di 20-80 vacche. Qui producevano burro e formaggi (come grana, stracchini e gorgonzola), vendevano vitelli, allevavano manze e utilizzavano i sottoprodotti caseari per nutrire i maiali. Al ritorno in montagna, producevano formaggi grassi pregiati durante l’alpeggio, commercializzati anche nelle fiere locali.
Il loro benessere economico è confermato da pratiche come l’affitto formale del fieno nelle cascine della pianura (con obbligo di restituire letame) e dalla capacità di acquisire l’usufrutto pluriennale dei pascoli alpini, spesso tramite aste pubbliche. Inoltre, la loro abilità commerciale contribuì alla nascita di un ceto imprenditoriale nel settore caseario lombardo del Novecento.Some sources from the first half of the 19th century offer a general idea of the seasonal migrations (transhumance) carried out every year by livestock breeders from certain valleys of central-eastern Lombardy toward the irrigated plains. Among these sources, a manuscript written by Luigi Cattaneo in the 1840s identifies the main areas of origin — such as Valsassina, Val Taleggio, Val Brembana, Val Seriana, and the Brescia mountain valleys — and sheds light on the social conditions of the families involved.
These were families of bergamini, transhumant dairy farmers, who had their homes and properties (especially meadows and pastures) in the mountains. Their true wealth lay in their livestock: herds of cows numbering from 20 to 80 animals. Although not a homogeneous group, they included both medium-sized entrepreneurs and wealthy breeders whose herds rivaled those of major tenants in the irrigated lowlands.
Their income derived from processing milk into butter and various cheeses — including grana, Gorgonzola, and several types of stracchino — and from raising and selling calves. They also raised pigs, using the byproducts of cheese production. Once back in the mountains in May, they produced high-quality summer cheeses, sold through intermediaries and at fairs like the one in Branzi.
These breeders had significant social and economic standing, demonstrated by the formal agreements they made with lowland farmers. Before moving to the plains, they signed contracts to rent hay and received housing and stables for free, while providing manure in return. They often also secured multi-year rights to alpine pastures through public auctions, underscoring their financial resources and business acumen. Over time, many of these bergamini became prominent figures in Lombardy’s dairy trade in the 20th century
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
