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
Nuove considerazioni paleontologiche e archeozoologiche sui resti faunistici del livello epigravettiano del Riparo Biarzo (UD).
No full textRiparo di Biarzo si trova a 160 m s.l.m. alla base di un terrazzo alluvionale lungo la sponda sinistra del Fiume Natisone nel Friuli orientale. Scavi del deposito sono stati diretti dal Prof. A. Guerreschi negli anni 1982, 1983 e 1984 in collaborazione con la Dr.ssa F. Bressan del Museo Friulano di Storia Naturale (UD). La sequenza antropica comprende livelli attribuibili all’Epigravettiano finale, Mesolitico e Neolitico. Si presenta lo studio condotto sui resti ossei rinvenuti nel livello Epigravettiano, datato 11.100 ± 125 14C B.P. (R-1850). Lo spettro faunistico evidenzia la presenza dominante di cinghiale tra gli ungulati e la prevalenza dell’orso bruno tra i carnivori. La situazione geografica di bassa pianura del giacimento ha favorito l’abbondanza di Sus scrofa mettendo in risalto un quadro faunistico singolare rispetto ad altri siti della fascia pedemontana e montana dell’Italia Nord Orientale alla fine del Tardiglaciale. L’analisi tafonomica ha evidenziato tracce di intervento antropico sulla maggior parte dei resti attribuibili ad ungulati. Un marcato sfruttamento del cervo a scopo alimentare è ben documentato in tutte le fasi della catena di macellazione. Tra i carnivori solo alcuni resti ossei di Ursus arctos presentano tracce di taglio da strumento litico.The shelter of Biarzo is located at the base of an alluvial terrace on the left side of the Natisone river at 160 m.l.s. in the eastern of Friuli. The deposit was excavated fr om 1982 to 1984 by Prof. A. Guerreschi and was divided into several layers dated to the final Epigravettian, the Mesolithic and the Neolithic periods. Our contribution presents the results of the study carried out on the faunal remains recovered in the epigravett ian layer, dated to 11.100 ± 125 14C BP. The predominance of wild boar among the ungulates is of particular interest when compared to other epigravett ian sites of northeastern Italy. Traces of human actions have been identifi ed on the most ungulates bones, whereas among the carnivores only a few bear bones have been clearly showed cut marks
La fine del Paleolitico medio nel Friuli occidentale. Le evidenze emerse da un sondaggio archeologico nella Grotta del Rio Secco.
No full textVengono presentati i risultati preliminari del Laboratorio di Ricerca Archeologica aperto nei messi di settembre e ottobre a Grotta del Rio Secco sull’Altopiano di Pradis. Lo scavo ha confermato la presenza di livelli di occupazione antropica riferibili al Musteriano finale e all’Epigravettiano, ipotizzata nel precedente sondaggio 2002, che definiscono un’elevata potenzialità scientifica per questo giacimento. Il Musteriano è rappresentato da manufatti litici ricavati su selci locali e da numerosi resti faunistici di ungulati recanti tracce di modificazione antropica. La frequentazione epigravettiana è invece testimoniata da uno scarso numero di strumenti e armature finite, ricavate da selci alloctone. Ricche sono anche le evidenze di colonizzazione di questa cavità da parte di Marmota marmota
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
