The Archaeological Sites of Gadani and Phuari Headlands (Las Bela, Balochistan, Pakistan)
Full text linkRas Gadani and Phuari were surveyed in the 2000s by the Italian Archaeological Mission in Las Bela
and Lower Sindh. The discovery of a few sites on the two headlands has shown the importance of the
Las Bela coast for the archaeology of the northern Arabian Sea. Both capes were already known for
their complex geological history, the presence of Bela Ophiolite outcrops and Parh Limestone formations
containing good quality red flint nodules, which were exploited at least since the beginning of the
Holocene. The recent surveys have led to the discovery of a few shell scatters, whose characteristics,
material culture remains and radiocarbon dating have contributed to improving our knowledge of the
peopling of the coastal region during two main periods of prehistory and history
Prehistoric Shell Middens, Seascapes and Landscapes at Lake Siranda (Las bela, Balochistan): Preliminary Results of the 2011 Fieldwork Season
Full text linkPreliminary results of the surveys conducted in 2011 along the shores of Lake Siranda (Las Bela, Balochistan) that led to the discovery of two shell middens radiocarbon dated to the 7th and 6th millennium uncal B
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
Archaeometric study of shells of Helicidae of the Edera Cave (North-Eastern Italy)
No full textThe Edera Cave, near Aurisina in the Trieste Karst, retains a stratigraphy that extends from
the Mesolithic to the modern era. At Sauveterrian layers, many specimens of Helix cincta
are present, which are considerably crushed, and a small percentage of which are also
blackened. Chemical analyses show that the blackened specimens were exposed to a
temperature of between 500 and 550°C, and suggest that many others were destroyed by fire
at temperatures of above 700°C. Consequently, only a part of the Helix cincta shells is
assumed to be the residue of human meals, since several factors render plausible an
accidental combustion of shells already present in the ground before the lighting of
Mesolithic hearth
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
