Aspetti antropologici, paleopatologici e musealizzabili dei Longobardi in Lombardia
No full textLe analisi condotte su circa 500 scheletri longobardi di Lombardia hanno permesso di ricostruire un primo quadro demografico e paleopatologico di riferimento. Gli studi hanno preso in considerazione sia gruppi di “prima generazione” sia necropoli in cui è evidente la mescolanza bioculturale con gli autoctoni. In questo caso interessante è il confronto con analoghe necropoli di altre regioni.
I risultati, infine, sono stati musealizzati in modo interattivo e con l’utilizzo di differenti tecnologie
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
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
Modification of facial morphology in children aged between 6 and 10 years: a pilot study for a new model of face aging
No full textEvery year a high number of missing people includes subadults: among 24111 missing persons recorded in Italy in 2010, 9336 were subadults (38.7% of all missing people). Missing subadults in time are more difficult to recognize since their facial morphology is still changing – and growing; photos taken before they went missing will therefore loose identification potential with time, since the face of the missing subject changes with age. In these cases, great importance is given to the so-called “face aging” models, which are supposed to develop the hypothetical face of the missing subadults several years after they went missing. In some cases, the face aging procedure is stressed up to the adult age.
In most cases, face aging processes are based on aesthetical and subjective criteria, without a scientifically valid base. The few methods based on mathematical models are developed from cranial measurements taken on subjects recruited within different age ranges. Face aging is therefore considered a procedure of adjustment of the original facial morphology to a hypothetical standard, specific for each age. However this approach does not take into account the individual modification of facial characteristics, and does not consider the real facial changes observed with growth in the same individual.
An experimental has been developed in order to verify the progressive modifications of facial morphology in a samples including 11 children aged between 6 and 10 years: 24 cranial measurements were taken on each subject. A 3D acquisition of the face with a 3D optical digitizer was performed, and the same measurements were taken on the 3D facial model. The craniometric analysis and 3D acquisition were repeated on each individual taking part in the experimental project at regular time intervals (twice a year) for several years.
This study presents the results of a re-evaluation of face aging through the comparison of facial changes examined on the 3D facial models and in vivo on the same individuals at different times and proves that much scientific data still has to be acquired before reliable face aging images can be guaranteed
The first anthropological study of the victims of World War I
No full textIn Italy many hundreds of victims of both armies who fought WWI still attend to be recovered and, if possible, identified and given back to their relatives. This study has as its objective to carry out a correct recovery, anthropological analysis and possible identification of these soldiers. Our plan has been elaborated so that it may involve various experts of different disciplines (archeologists, historians, antropologists, but also genetists and entomologists). So far, in this research project, 35 recovered skeletons have been studied. Thus the biological profile was defined (sex, age, stature and ancestry) then pathologies as well as trauma. The first results show the presence of adult men but also of adolescents. The subjects show diseases of a degenerative type (arthrosis, reumatoide arthritis), as well as perimortal lesions linked to blunt trauma, explosions, or due bullet wounds
