Paleobiologia. Resti umani recuperati da tombe di età daunia (VI-IV sec. a.C.) in località Monte Civita
No full textNello studio del passato l’interpretazione delle fonti archeologiche e di quelle storiografiche riceve un prezioso contributo dalle indagini antropologiche effettuate sui resti biologici delle sepolture.
Tale circostanza si rivela con maggiore evidenza quando l’attenzione degli studiosi è focalizzata su periodi storici particolari, quale è stato il IV secolo a.C., dominato dall’epopea del re macedone Alessandro il Grande e dei suoi numerosi emuli, tra i quali spicca, nel Meridione d’Italia, Alessandro il Molosso.
Si fa riferimento ad un periodo storico ricco di eventi bellici, culminati nell’invasione della Daunia e della Peucetia da parte dei popoli di lingua osca: in tal senso la comparsa di nuovi flussi genici nei territori di occupazione ed il mutato panorama delle risorse ambientali e delle condizioni socio-politiche determinò la probabile rottura degli equilibri patocenotici tradizionali ed un aumento degli stress a carico dei nuclei umani indigeni.
Si rivela di grande interesse, quindi, effettuare l’indagine antropologica su di un campione scheletrico, seppur limitato, di 8 individui, distribuiti in tre tombe, proveniente dal sito archeologico garganico di Monte Civita, nel territorio di Ischitella (Foggia) e datato IV secolo a.C..
Ci si riferisce alle tombe 1, 2, e 3 di una necropoli da anni oggetto di scavi clandestini e depredazioni e recuperate in seguito ad un intervento di scavo di emergenza curato dalla Soprintendenza Archeologica della Puglia con la collaborazione della Guardia di Finanza.
L’indagine antropologica dei resti scheletrici ha previsto la pulitura ed il restauro degli stessi, l’attribuzione del numero minimo di individui, la diagnosi del sesso e la determinazione dell’età di morte, il calcolo della biomassa corporea e della statura in vivo, l’indagine osteometrica ed osteoscopica, il rilevamento di marcatori dentari e scheletrici di stress causati da attività occupazionali, carenze nutrizionali e malattie, il riscontro di patologie, l’applicazione della cross sectional geometry sulle diafisi delle ossa lunghe.
Considerando il periodo storico caratterizzato da importanti movimenti migratori delle popolazioni italiche di lingua osca, si è anche proceduto ad un confronto tra alcune variabili metriche craniche di tre degli individui in studio con quelle di un campionamento indigeno e di altre popolazioni sincroniche tra cui sanniti, lucani, etruschi e greci.
Lo studio è stato effettuato utilizzando i valori di distanza biologica tra le serie confrontate, ottenuti dall’applicazione di appropriate metodiche di analisi multivariata

DNA extracration and Anthropological Aspects from 6th to 7th Century A.D. Bone Remains.
No full textIn the archeological site of the early Christian Episcopal complex of Saint Peter, in Canosa di Puglia (Bari, Italy), during the operations of archaeological excavations, tombs were discovered. They were dated between the sixth and seventh centuries AD with carbon 14 methodology. Five skeletons were found in the 5 tombs: 28A: male individual, 43 years old. The height was 170 cm; the biomass was 65.7 kg. The analysis of the bones indicated several noteworthy pathologies, such as a number of hypoplasia lines of the enamel, the presence of Schmorl hernias on the first 2 lumbar vertebrae, and the outcome of subacromial impingement syndrome. 28E was a male individual, with a biologic age of death of between 44 and 60 years. The height was 177 cm. He had a posttraumatic fracture callus of the medial third of the clavicle, with an oblique fracture rima. 29B was a female individual, 44–49 years old. The height was 158.8 cm; the biomass was 64.8 kg. There was Wells bursitis on the ischial tuberosity on both sides. 29E was a male individual, 45–50 years old. The height was 169.47 cm; the biomass was 70.8 kg. The third and the fourth vertebrae showed Baastrup syndrome (compression of the vertebral spine). There were radiologic signs of deformity on the higher edge of the acetabula and results of frequent sprains of the ankles. 31A was a male individual, 47–54 years old. The height was 178.65 cm; the biomass was 81 kg. The vertebral index showed a heavy overloading in the thoracic lumbar region. There were bony formations under the periosteum on both on the higher and medium facets of the first metatarsus and on the higher and lateral facets of the fifth metatarsus on both sides. As the topography indicates, these small ossifications coincided with the contact points between the back of the foot and parts of the upper shoe. From the osseous remains, in particular from the teeth (central incisors), the DNA was extracted and typed to identify potential family ties among all the subjects. The extraction technique used came from the DNA Promega technique, partially modified by the authors. Stay times of the sample in the extraction buffer were increased
Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe 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
Get PDF“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
Get PDFWe 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
Get PDFWe 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
