Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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

Get PDFWe 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

“Fossil Art”: The importance and value of the palaeobiodiversity in the Naturtejo Global Geopark, under UNESCO (Portugal)
No full textThe Geopark Naturtejo da Meseta Meridional (Centre Iberian Zone, Portugal) is developing the inventory of geological and mining heritage since 2004. This inventory in a concluding stage shows 18 fossil geosites, including classical and newly discovered sites evidencing international to regional importance. Some of the oldest fossils of the Iberian Peninsula were found at Naturtejo Geopark, corresponding to Middle - Late Ediacaran marine cyanobacteria found in a turbidite sequence cropping out at Erges River valley, near Salvaterra do Extremo locality. Most of the inventoried fossil sites belong to the Armorican Quartzite Formation, which is a peri-Gondwanan distributed biofacies famous for its trace fossils, such as the classic Skolithos (in piperock ichnofabrics) and the Cruziana rugosa group, as well as for obolid brachiopod shell beds, but lacking almost any other body fossils. The Penha Garcia Ichnological Park, a popular attraction of Naturtejo Geopark, is becoming internationally recognized for the unusual abundance and preservation of such trace fossils, with remark for the diverse feeding patterns made during the life cycle of giant trilobites. The remaining Ordovician period is well represented by fossil sites with calymenid, illaenid, dalmanitid, trinucleid and pliomerid trilobites, bivalves, orthoceratid cephalopods, orthid brachiopods, didymograptid graptolites, diploporitid echinoderms and ostracod arthropods. Fossils from Lower Silurian age (Llandovery) were found recently and for the first time in Naturtejo Geopark. Graptolites, cephalopods, bivalves and possible remains of eurypterids are among the first fossils identified. In the continental Cenozoic deposits, the fluvial terrace of Pinhal records the first incision of the Tejo River on the Neoproterozoic-to-Lower Palaeozoic and Palaeogene-Neogene rocks of Naturtejo Geopark during lower Pleistocene. In these conglomerates, at least 7 fossil tree trunks were found, due to the erosion by the Tejo river of Middle - Late Miocene aged arkoses and their deposition in flooding plain environment. The fossil trees were found by the Romans almost two thousand years ago during exploitation of the fluvial conglomerates for gold. The most recent fossil site was dated to 33500 years and corresponds to sandstones from the last fluvial terrace developed by the Tejo River. Foz do Enxarrique fossil site provided remains of large mammals such as red deer and auroch. But the most important finding was the remains of Elephas antiquus, corresponding to the latest record of this important elephant before its final extinction from Europe mainland. Fossil sites and palaeontological data achieved from active ongoing research at Naturtejo Global Geopark are being included in several tourism packages and educational programmes proposed by Naturtejo for national and international tour operators and schools. Cruziana trace fossils and trilobites that produced them have become the geobrand for nature tourism and landscape touring, not only for the Geopark area but also for the whole Portuguese Centre Region. Actually, they are already being used in innovative business opportunities
