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
A morphotectonic analysis of the Agri Valley, Southern Italy: alluvial and marine terraces as indicators of active tectonics.
No full textIn this paper a detailed morphotectonic analysis of both the Quaternary alluvial and marine terraces of the Agri River (one of the most tectonically active regions of southern Italy) is presented. Here the occurrence of several orders of Pleistocene-Holocene fluvial terraces along the whole Agri Valley and the presence of a sequence of Pleistocene-Holocene marine terraces along the Ionian coastal stretch of the river mouth, strongly suggest that the portion of Lucanian Apennines and Bradanic foredeep crossed by the Agri River have undergone a process of tectonic uplifting, ranging from about 0.2 mm/a to more than 2.5 mm/a, during Quaternary
Ontologia, realtà e conoscenza
No full textNella tradizione filosofica occidentale l’ontologia rappresenta una disciplina centrale, il cui scopo è quello di esplicitare le caratteristiche universali della realtà, i suoi fondamenti costitutivi, i suoi primi principi. In tale prospettiva,
essa è assimilabile a quella “filosofia prima” (epistéme tòn pròton arkòn kai
aitiòn theoretiké) di cui parla Aristotele e che ha assunto il classico nome di “metafisica”. Tuttavia nel corso dei secoli il concetto di metafisica ha acquisito un altro significato, cioè quello di analisi delle strutture e dei livelli ontologici
del reale che eccedono l’esperienza di ciascun individuo e che riguardano questioni
cruciali nella riflessione filosofica quali, ad esempio, l’esistenza di Dio, il problema del male, l’origine dell’Universo. Nel secolo scorso l’ontologia si è ulteriormente articolata come studio dei diversi ambiti del reale, cosicché i vari enti di cui si occupano le differenti discipline costituiscono l’ambito di ontologie
“regionali” (l’ontologia della fisica, l’ontologia della biologia, l’ontologia della matematica, ecc).
Questo volume è dedicato allo studio dei rapporti complessi e fecondi tra l’ontologia e la conoscenza secondo molteplici prospettive di analisi e di ricerca. I saggi in esso raccolti intendono contribuire sia alla riflessione critica nell’ambito
degli studi e delle ricerche sulle relazioni tra l’ontologia e la conoscenza sia all’approfondimento di alcuni temi e questioni più generali di carattere metafisico e gnoseologico
Comment on ‘‘Late Cenozoic uplift of southern Italy deduced from fluvial and marine sediments: Coupling between surface processes and lower-crustal flow’’ by Westaway R. and Bridgland D. (Quaternary International 175, 86–124)
No full textWe consider it opportune to comment on some of the statements proposed by Westaway R. and Bridgland D. (2007) in their paper ‘‘Late Cenozoic uplift of southern Italy deduced from fluvial and marine sediments: Coupling between surface processes and lower-crustal flow’’ (Quaternary International 175, 86–124), with particular reference to the first half of the paper focusing on the geomorphological analysis of the Pleistocene marine and fluvial terraces that occur along the Ionian coastal area of the Basilicata region (Southern Italy). As authors of some of the papers cited in [Westaway, R., Bridgland, D. 2007. Late Cenozoic uplift of southern Italy deduced from fluvial and marine sediments: coupling between surface processes and lower-crustal flow. Quaternary International 175, 86–124.], we wish to point out several significant inaccuracies in their paper, which are generally due to the misunderstanding or misuse of literature data and which regard (i) both the vertical distribution and the timing of the whole Ionian marine terrace sequence, (ii) the correlation between marine terraces and marine isotopic stages (MIS), (iii) the interaction between uplift and erosion processes in Basilicata, and (iv) the morphogenic model of the fluvial terraces of the Agri River. It is our opinion that the Late Cenozoic uplift magnitudes, rates and modelling proposed by the authors for this key-area of southern Italy using such unreliable data are, therefore, to say the least, questionable
