Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
Protohistoric pastoral landscape in northern Istria revealed by airborne LiDAR: hill forts, enclosures and long linear walls in the Mali Kras plateau (southwestern Slovenia)
This paper presents the results of an international research aimed at investigating the ancient landscape of the Mali Kras plateau, a sector of northern Istria (southwestern Slovenia). The remains of two main protohistoric hill forts, Mali Kras and Socerb, and a few minor sites were already reported from this area. A cemetery, associated with Socerb hill fort, was in use between the sixth century BC and the first century AD. Airborne LiDAR remote sensing of Mali Kras plateau has allowed to identify several unknown archaeological features, ranging from approximately square features (30 × 30 m) to larger enclosures with different shapes, very long linear features and stone mounds. The elaboration and digitization of high-definition remote sensing data compared with historical cartography, field surveys, targeted small-scale excavations and thermoluminescence dating have been performed in order to decode the complex archaeological palimpsest. The square structures can be attributed to Middle-Recent Bronze Age on the basis of pottery finds. These structures are located close to natural passages from the plateau to the gulf of Trieste, in areas with low visibility and scarcity of soil, which were traditionally used for grazing activities. The other identified enclosures, some of them sharing a similar chronology, were also probably used for pastoral activities but for other purposes since their shape and size are different. Two main long drystone walls define the southeastern sector of Mali Kras plateau in correspondence of the most accessible entrance to the area. The preliminary data and comparisons with similar structures suggest these walls could correspond to protohistoric linear boundaries built to delimit grazing or agricultural areas under direct control of the nearby settlements. The enclosures identified at Mali Kras plateau, most probably connected to herding activities, and perhaps the long linear walls too, could reflect the development of new husbandry practices in the Middle-Recent Bronze Age in the karst areas of the north Adriatic hinterland, such as observed in the alpine territory
Thermoluminescence (TL) characterization and dating feasibility of ancient glass mosaic
To achieve a better comprehension of the thermoluminescence (TL) properties and dating feasibility of mosaic glasses, a study on the connections between chemical composition and general TL behavior of glass tesserae has been carried out. Elemental analysis of the samples has been performed through electron microscopy with microprobe, inductively coupled plasma and X-ray fluorescence spectrometry. Preliminary results, relative to the study of the TL behavior of different groups of glass mosaic tesserae, classified by provenance and by chemical analyses, are reported and discussed. © 2000 Elsevier Science Ltd
Variations on the Author
“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
We 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
We 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
We 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
