Old Acquaintances Reappear: The Human Remains in the “Chiesa Vecchia” of Filetto, L’Aquila, Central Italy
No full textShortly after the discovery of mummies in the village of Calascio, inner Abruzzo region an additional site in the same area has been brought to light in Filetto, a small hermit belonging to the municipality of L’Aquila. Since 2001, a collection of human remains dating back to 19th century was known to be present inside a crypt beneath the ruins of the Chiesa Vecchia (old church). The recent recovery of the ruined church allowed us to come across the remains once again. The human remains from Filetto represent the seventh known collection of mummified bodies in the inner Abruzzo region, enhancing the assets of bioanthropological interests in this area. By analogy with Calascio and other local sites, we proposed a thorough investigation of bodies and burial goods in order to trace a bioanthropological and paleopathological profile of these individuals
A Wideband Single-Feed Circularly Polarized Stacked Patch Antenna
Full text linkWe present a circularly polarized single-feed stacked patch antenna with wide axial ratio bandwidth, suitable for both coaxial probe feeding and coplanar microstrip feeding. The antenna is composed of two patches with truncated corners connected together using four pins. The circularly polarized antenna has been designed using CST Studio Suite in the upper part of the UHF frequency band. A prototype has been fabricated using low-cost 3D-printing manufacturing technology. In this regard, both the dielectric substrate and the support for the stacked patches have been realized with a 3D-printed Polylactic Acid. Measured results provide a 34% -10 dB reflection coefficient bandwidth (between 2.14 and 3.03 GHz) and a 3 dB axial ratio bandwidth of 25% (between 2.31 and 2.97 GHz), with a flat gain in the overlapped (axial ratio-reflection coefficient) bandwidth that coincides with the axial ratio bandwidth and a peak gain of 8.5 dBic
Three cases of developmental dysplasia of the hip on partially mummified human remains (Roccapelago, Modena, 18th Century): a study of palaeopathological indicators through direct analysis and 3D virtual models [Trois cas de dysplasie développementale de la hanche chez des individus partiellement momifiés (Roccapelago, Modène, 18e siècle): étude des indicateurs paléopathologiques par analyses directe et virtuelle]
No full textDevelopmental dysplasia of the hip (DDH) is caused by a delay in the development of the acetabular cavity, leading to an anomaly in the angle of the acetabular roof. As a result, the femoral head and the acetabular cavity do not interact normally. The identification of three cases of DDH among the remains discovered in the most recent unit from the crypt at Roccapelago (Modena, Italy) enabled us to discuss the presence of DDH in this region during the 18th century. All three cases are bilateral and Dunn class I, two have been identified as male and one as female. These DDH cases are very likely mainly due to mechanical factors such as the breech position of the foetus, perhaps associated with birth order. But given their overall similarity, they may also have resulted from the practice of swaddling new-borns. In addition, current data from the Italian Ministry of Health suggests that the incidence of DDH has remained stable in this region from the 18th century to the present. The ongoing study of remains from earlier units should bring a better understanding of the particular prevalence of DDH at Roccapelago.La dysplasie développementale de la hanche (DDH) résulte d’un retard dans le développement de la cavité acétabulaire conduisant à une altération de l’inclinaison du toit acétabulaire. En conséquence, la tête fémorale et la cavité cotyloïdienne n’interagissent pas normalement. L’identification de trois cas de DDH parmi les restes découverts dans l’unité stratigraphique la plus récente de la crypte de Roccapelago (Modène, Italie) nous permet de discuter de la présence de DDH dans cette région au cours du 18e siècle. Dans les trois cas, identifiés comme deux hommes et une femme, la pathologie est bilatérale et de classe Dunn I. Ces cas de DDH sont vraisemblablement principalement dus à des facteurs mécaniques tels que la position en siège du foetus, probablement associée au rang de naissance. Mais compte tenu de leur similitude globale, ils peuvent avoir été causés par l’utilisation de langes chez les nouveau-nés. En outre, les données actuelles du ministère italien de la Santé suggèrent que l’incidence de la DDH est demeurée stable dans cette région, du 18e siècle jusqu’à nos jours. L’étude en cours des restes des unités stratigraphiques antérieures favorisera une compréhension plus profonde de la particularité de la prévalence de DDH à Roccapelago
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
The Mummies in the Church of Santa Maria delle Grazie, Calascio: A New Site in the Inner Abruzzo Region, Central Italy
Full text linkThe inner Abruzzo region, corresponding to the province of L’Aquila, is a land of mountains and highlands in central Italy. Its environmental conditions greatly foster spontaneous mummification, and the area is well known for the human mummies found in the last decades. We present a newly discovered collection of mummified remains in the village of Calascio, located 1,210 meters above the sea level, near Gran Sasso Mountain. Here, the Franciscan convent of Santa Maria delle Grazie was built in 1594. The preliminary survey of a crypt in the conventual church allowed us to observe wooden coffins with at least seven mummified bodies still in their clothes, and several bony remains. Most likely, the mummies date back to the second half of the 19th century, and belonged to laypersons. Preservation was certainly due to the cold dry environment of the crypt. The recovery of the entire series will take place through speleological techniques according to stratigraphic relationships, in order to trace a bioanthropological profile of this small community members
