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
Microfacies analysis of deep-water breccia clasts: a tool for interpreting shallow- vs. deep-ramp Paleogene sedimentation in Cephalonia and Zakynthos (Ionian Islands, Greece)
No full textThe tectono-sedimentary evolution of the western Pre-Apulian zone of the Hellenides is investigated through comparison of the microfacies of clasts from breccia beds within gravity-flow successions of Zakynthos with those of the carbonate ramp of the westernmost part of Cephalonia. After the demise of a Late Cretaceous rimmed platform, the Paleogene successions of the Ionian Islands represent different facies patterns of a carbonate ramp. In western Cephalonia (Lixouri peninsula), different successions suggest the existence of five juxtaposed tectono-sedimentary sectors, remnants of a larger carbonate ramp. In Zakynthos, six distinct sectors with different toe of slope-proximal basin stratigraphic successions were recognized, all affected by a Paleocene-Lower Eocene hiatus, which can be grouped into two tectono-sedimentary units. Through the analysis of successions of the Lixouri peninsula and breccia clasts from Zakynthos, 24 age-constrained and spatially related Upper Cretaceous-Oligocene microfacies types were recognized, illustrating a variety of sedimentary environments. These microfacies were allocated to five different stages in the evolution of a tectono-sedimentary model from down-faulting, through backstepping, uplift and dismantling, to fault-controlled subsidence and finally complete drowning. Various microfacies of the clasts can be correlated to the stratigraphic record of the Lixouri peninsula, whereas others are absent there. Thus an inferred adjacent source terrain, now tectonically obliterated, was likely located west of the present-day Ionian Islands
Ricerche sugli aspetti monetari e sociali di Creta in età ellenistica: le ragioni di un confronto / Investigations on monetary and social aspects of Crete in the Hellenistic age: the reasons for a debate
No full textFor a long time now, studies on the economy of Greek cities have increasingly focused on material culture and numismatics. Today, there is a deep awareness that detail studies can yield crucial information about issues of production, exchange, and consumption of goods, and – in combination with written sources – add to our knowledge of how the economy functioned and how it was influenced by the social, political, and cultural context. Survey of economic and financial questions concerning the Hellenistic and late Hellenistic periods
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
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
