Les productions céramiques en Sardaigne au IVe millénaire av. J.-C. Nouvelles données sur le village de Su Coddu-Canelles (Selargius, Cagliari)
No full textCette étude fait partie du projet de recherche de l’Université de Sassari « Archéologie des habitats préhistoriques sardes », dirigé par Maria Grazia Melis. Le but principal est la reconstitution du cadre environnemental et socio-économique des phases finales du Néolithique sarde et du début du Chalcolithique, caractérisé par les ultimes aspects du « phénomène » Ozieri. La première étape de la recherche a été consacrée à l’analyse typologique de la céramique dérivée d’Ozieri des IVe et IIIe millénaires av. J.-C., et a impliqué la réorganisation des données publiées, l’élaboration d’une sériation et d’une hypothèse de séquence culturelle. Par la suite, la fouille du village de Su Coddu-Canelles (Selargius, Cagliari) a permis l’acquisition de données primaires et de nouvelles datations 14C, qui confirment la séquence déterminée par l’analyse typologique. Enfin l’étude morpho-technologique de la production artisanale a montré son caractère « opportuniste » qui nous amène à une nouvelle vision de l’organisation de la production et de l’économie du villageQuesto studio si inserisce nell’ambito del progetto di ricerca dell’università di Sassari Archeologia degli insediamenti preistorici della Sardegna, coordinato da Maria Grazia Melis. Lo scopo principale è la ricostruzione del quadro ambientale e socioeconomico delle fasi finali del Neolitico sardo e dell’inizio del Calcolitico, caratterizzate dagli ultimi aspetti del “fenomeno” Ozieri.
La prima fase della ricerca è stata dedicata all’analisi tipologica della ceramica di derivazione Ozieri del IV e III millennio BC, che ha implicato la riorganizzazione dei dati editi, l’elaborazione di una seriazione e di un’ipotesi di sequenza culturale. Successivamente lo scavo dell’insediamento di Su Coddu-Canelles (Selargius, Cagliari) ha permesso di acquisire dati primari e nuove datazioni al C14, che confermano la sequenza determinata dall’analisi tipologica. Infine lo studio morfo-tecnologico della produzione artigianale ha mostrato il suo carattere “opportunistico”, che ci ha portato ad una nuova visione dell’organizzazione della produzione e dell’organizzazione economica del villaggioThis study is part of the research project of the University of Sassari, called “Archaeology of Sardinian prehistoric settlements ", led by Maria Grazia Melis. The main aim is the reconstruction of environmental and socio-economic phases of the Sardinian Neolithic and Early Eneolithic, characterized by the final aspects of the "phenomenon" Ozieri.
The first stage of research was dedicated to the typological analysis of by-pass Ozieri ceramic of 4th and 3rd millennium B.C., which has involved the reorganization of the published data, the development of a seriation and an assumption of cultural sequence. Thereafter, the excavation of the village of Su-Coddu Canelles (Selargius, Cagliari) allowed the acquisition of primary data and new C14 dating, which confirmed the sequence determined by the typological analysis.
Finally, the morpho-technological study of production has shown its "opportunistic" nature, which brings us to a new vision for the organization of the production and economic organization of the village
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
Aspetti tecnologici e morfologici della ceramica eneolitica. Nuovi dati dall’insediamento di Su Coddu-Canelles (Selargius, Cagliari)
No full textNell’ambito di una più vasta ricerca sulla transizione dal Neolitico all’età del Rame in Sardegna, affrontata attraverso il riesame dei dati editi e l’apporto di nuovi elementi provenienti da analisi archeometriche su dati inediti, il presente studio è finalizzato all’approfondimento degli aspetti cronologici, tecnologici e morfologici di contesti Sub-Ozieri, con particolare riferimento all’insediamento di Su Coddu-Canelles (Selargius, Cagliari) che presenta il più importante contesto relativo a questa fase. In questa sede si presentano i risultati preliminari dello studio tipologico, tecnologico e delle analisi archeometriche delle ceramiche della struttura 48.TECHNOLOGICAL AND MORPHOLOGICAL ASPECTS OF AENEOLITHIC CERAMIC. NEW DATA ON “SU CODDU-CANELLES” SETTLEMENT. - This study deals with the chronological, technological and morphological aspects of pottery coming from Sub-Ozieri setting, particularly from “Su Coddu-Canelles” (Selargius, Cagliari) settlement, which represents the main site pertaining to this cultural period. Here the preliminary results of typological, technological and archaeometric studies are exposed. This sectorial research, which is based both on literature data and new archaeometric evidences, is part of a general search program on the transition between the Neolithic and the Copper Age in Sardinia
Upper Tremadoc–Lower Arenig? Anisograptid–Dichograptid fauna from the Cabitza Formation (Lower Ordovician, SW Sardinia, Italy)
No full textThe discovery of the anisograptid graptolite Araneograptus murrayi (Hall, 1865), the dichograptids Clonograptus (Clonograptus) cf. rigidus
(Hall, 1858) and Clonograptus (Clonograptus) cf. multiplex (Nicholson, 1868) and of two unassigned species of Didymograptus in the Late
Tremadoc–Early Arenig? sediments of the Fluminese area (SW Sardinia) adds new data on the biostratigraphy and palaeoecological setting of the
Cabitza Formation, as well as on the paleobiogeographical distribution of these taxa

Full text linkRetiolites angustidens, trovato in un blocco isolato di calcare a Orthoceras nell’area di Monte Cocco in
associazione con Monograptus cf. priodon, viene qui descritto e figugurato per la prima volta nelle Alpi Carniche: in precedenza
la sua presenza, infatti, era stata segnalata, ma mai documentata. Dato che tutti i graptoliti rinvenuti hanno un limitato valore
stratigrafico, l’età precisa dell’associazione studiata è attribuita alla Biozona a Pterospathodus am. amorphognathoides (Llandovery
sup.) in base ai conodonti.Retiolites angustidens is described and figured for the first time from the Carnic Alps, from a loose block collected
from Mt. Cocco area. ! e association includes also Monograptus cf. priodon: this species, in fact, was previously reported,
but never documented, from this area. Since all the graptolites found have a limited stratigraphic value, the precise age of
the studied association is determined by conodonts as belonging to the latest Llandovery (Pterospathodus am. amorphognathoides
conodont Zone)
