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
Long-Range Versus Short-Range Prehistoric Pastoralism. Potential of Palaeoecological Proxies and a New Record from Western Emilia, Northern Apennines, Italy
No full textThe timing of the rise of upland pastoralism and the extent of the seasonal mobility of early shepherds are key issues in the later prehistory of the Mediterranean. The archaeological record from Liguria (NW Italy), points to an increasing relevance of animal husbandry since the beginning of the Middle Neolithic, from the 5th millennium BC onwards. Thick stabling deposits and zooarchaeological assemblages from cave sites show the importance of sheep and cattle farming. Moreover, palaeoecological data from bogs and mires have suggested the use of pastures located at mid-high elevations and anthropogenic landscape modifications. The paper re-discusses the debated issue of long- vs short-range transhumant pastoralism in view of the archaeological and palaeoecological data from the region. A new case study is presented: dung spore analysis has been carried out from a high-altitude mire located in western Emilia, suggesting the possibility of a limited environmental impact of the first pastoral groups and of a stable presence of wild ungulates around the site
La Collezione Guidi nel Museo Archeologico di Grosseto. La necropoli di Colle Baroncio e la prima età del Ferro a Vetulonia
No full textFra il 1886 e il 1913 il Comune di Grosseto acquisì per il Museo Civico gli oggetti archeologici che i fratelli Antonio e Angelo Guidi di Vetulonia stavano scavando in una loro proprietà a O della città antica: Colle Baroncio.
La collezione è rimasta a lungo inedita e solo oggi, grazie allo studio accurato di Lionello F. Morandi, può essere pubblicata integralmente. Si tratta senza dubbio di un nuovo importante contributo su Vetulonia, sempre troppo poco nota
An ethnoarchaeological case study of dung fungal spore and faecal spherulite taphonomy in a pastoral cave deposit
No full textIn alkaline cave sediments, the presence of faecal spherulites is regarded as a reliable indicator of animal dung. Spores of coprophilous fungi are nowadays frequently employed as grazing indicators in palaeoecological sequences, but their use in dryland pastoral deposits is not routine in geoarchaeological practice. The paper assesses the relationship between the occurrence of spherulites and dung fungal spores from an abandoned rock shelter used as a stable for several decades. A clear match between these proxies is shown, and their distribution across the sediments is discussed, highlighting the potential of coprophilous spore analysis from archaeological stabling deposits, alongside other established dung indicators. The abundance of other microfossils (parasite eggs, coccolith plates and freshwater indicators) is also quantified and discussed
Reconstructing dietary practices at Tell Kamid el-Loz (Lebanon) during the Bronze and Iron Age III / Persian to Hellenistic periods using plant micro-remains from dental calculus and stable isotope analysis of bone collagen
No full textTell Kamid el-Loz (Lebanon) was an important Bronze Age urban center that dominated one of the central crossroads of the Ancient Near East, connecting Egypt and the Levant with northern Mesopotamia, Anatolia, and Syria, as well as the interior with the Mediterranean coast. However, by the early Iron Age, the site had shrunk to a small rural settlement. Later, in the Iron Age III / Persian-Hellenistic, only enigmatic pits and a large cemetery remained. In this paper, we analyzed plant micro-remains from the dental calculus of 15 individuals (3 from the Middle Bronze Age II and 12 from the Iron Age III / Persian-Hellenistic) and δ13C and δ15N stable isotope data from tbulk bone collagen of 74 individuals (10 from the Middle Bronze Age II and 64 from the Iron Age III / Persian-Hellenistic) and 13 Late Bronze Age animal bones (7 Ovis/Capra and 6 Bos). Our results indicate general stability of human diet throughout the Middle Bronze Age II and the Iron III / Persian-Hellenistic periods, with a reliance on C3 plant crops and terrestrial animals also consuming C3 plants. In the later period, the plant micro-remains indicate the consumption of C4 plants and sedges, and the stable isotope analysis indicates differences in diet between males and females
