Influence of the Roman road network on the biological proximity of Italic Abruzzo populations through mean measure of divergence analysis
No full textSince the tenth century BC, the Abruzzo region has hosted different Italic populations. According to historical sources, they originated from an ancestor population following the ritual “ver sacrum” migration. Contact among the populations within the region was always difficult, as Abruzzo is crossed longitudinally by the highest peaks of the Apennines chain. It was only after the Roman conquest from the fourth century BC that the construction of a new road system allowed quick and safe connections among some of the populations. This study was designed to use non-metric skeletal traits and mean measure of divergence analysis to determine the effective biodistance between five nuclei populations (Scurcola Marsicana, Tortoreto, Opi, Sulmona, Teramo) and whether this was influenced by the construction of the Roman road network. The statistical analysis thus defined the effective common origin of these populations. It can be seen that the populations that lived alongside the main Roman communication routes (Tortoreto, Teramo, Sulmona) had a greater degree of hybridisation than those that were further from the road system (Opi), who were instead biologically isolated
Author Correction: Histological and chemical diagnosis of a combat lesion in Triceratops (Scientific Reports, (2022), 12, 1, (3941), 10.1038/s41598-022-08033-2)
No full textThe original version of this Article contained errors, where the place of discovery of Triceratops horridus, known as Big John, was incorrectly stated as ‘Hell Creek Formation (Upper Cretaceous; MT, USA).’ As a result, in the Abstract, “Here, we present the case of the Triceratops horridus known as Big John, which is one of the largest specimens discovered in the Hell Creek Formation (Upper Cretaceous; MT, USA).” now reads: “Here, we present the case of the Triceratops horridus known as Big John, which is one of the largest specimens discovered in the Hell Creek Formation (Upper Cretaceous; South Dakota, USA).” Additionally, in the third paragraph of the Introduction, “The specimen of Triceratops horridus known as Big John (due to its large size) was discovered in 2014 in the Upper Cretaceous Hell Creek Formation (MT, USA), from where numerous remains of Ceratopsidae (Chasmosaurinae) have been recovered4– 6 (see Supplementary Information).” now reads: “The specimen of Triceratops horridus known as Big John (due to its large size) was discovered in 2014 in the Upper Cretaceous Hell Creek Formation (South Dakota, USA), from where numerous remains of Ceratopsidae (Chasmosaurinae) have been recovered4– 6 (see Supplementary Information).” The original Article has been corrected
The human remains of the funerary complex of neferhotep (Xviiith–xxth dynasty, valley of the nobles, luxor, egypt): Taphonomy and anthropology
No full textThe Valley of the Nobles is a burial area that is located between the Valley of the Kings and the Valley of the Queens, together with which it constitutes the Theban Necropolis. The Valley of the Nobles houses the tombs of ancient aristocratic families, which include the monumental complex of the Neferhotep tomb, catalogued as TT49 (XVIIIth Dynasty). The funerary monument of Neferhotep also includes tombs TT187, TT347, TT348, TT362, and TT363, although tombs TT347, TT348 (Ramessid Period), and TT363 (XIXth Dynasty) remain closed. Tombs TT49, TT187, and TT362 contained numerous human remains in different states of conservation. Those in tomb TT187 were attributable to at least 71 individuals, who showed evident signs of combustion, and also taphonomic alterations that had occurred in recent decades. The context of tomb TT362 was different, as it contained animal and human mummified remains that were disarticulated and showed few signs of exposure to high temperatures. These remains were attributable to 64 individuals. Tomb TT49 contained the remains of a single individual inside the burial chamber. The taphonomic and anthropological data suggest that the tombs within the funerary complex of Neferhotep were frequented not only by modern populations, as they also testify to the ancient reuse of tombs in different phases from the Ramessid to Ptolemaic periods

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
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
