Sulcis in transition: le fasi punico-arcaiche dell'abitato di Monte Sirai (Carbonia, Sardegna) tra luci e ombre
No full textAt the hilltop site of Monte Sirai, which has been investigated since the early 1960s, evidence from the recent excavations
has shed new light on the settlement dynamics between the late Iron Age and the Roman Republican period. Particularly
relevant is the new evidence that points to continuity throughout the Punic period, which downplays the traditional interpretation
of a major destruction event following Carthaginian conquest. It is suggested that this 5th-century phase has long been
overlooked because of two distinct phases of urban re-planning that took place at the site in the 4th and 2nd centuries BC
La "nuova" necropoli punica di Monte Sirai (Carbonia-Sardegna). Il problema del V sec. a.C. dalla prospettiva funeraria (scavi 2009-2016)
No full textInvestigation of the cemeteries of Monte Sirai has greatly helped to reassess our understanding of the Phoenician
and Carthaginian presence in southwestern Sardinia, especially with regard to the late Archaic and early Punic phases. It has
usually been emphasized that the settlement of Monte Sirai was almost totally destroyed after the Carthaginian conquest, but
new burial evidence instead clearly demonstrates continuity throughout the Punic period. Infant burials and tombs of adults
of both sexes allow us to identify patterns and features of the human population at Monte Sirai at the time of Carthaginian
expansion over the western Mediterranean
Mediterranean precipitation isoscape preserved in bone collagen δ2H
No full textThe prehistory of the Mediterranean region has long been a subject of considerable interest, particularly the links between human groups and regions of origin. We utilize the spatial variation in the δ2H and δ18O values of precipitation (isoscapes) to develop proxies for geographic locations of fauna and humans. Bone collagen hydrogen isotope ratios (δ2H) in cattle (and to a lesser extent, ovicaprids) across the Mediterranean reflect the isotopic differences observed in rainfall (but δ18O values do not). We conclude that δ2H in herbivore bone collagen can be used as a geolocation tracer and for palaeoenvironmental studies such as tracing past isotopic variations in the global hydrological cycle. In contrast, human bone δ2H values are relatively tightly grouped and highly distinct from precipitation δ2H values, likely due to human-specific food practices and environmental modifications. Given the inter-species variability in δ2H, care should be taken in the species selected for study
An agricultural field of Hellenistic date at Pauli Stincus, Terralba, Sardinia
No full textExcavation at Pauli Stincus in Sardinia has revealed an ancient plough soil, with associated evidence of intensive prehistoric agricultural activities.We gratefully acknowledge the support of Massimo Casagrande, Massimiliano Pilloni and Sandro Perra, without
whom the excavation would never have happened. We also thank the regional Soprintendenza and the Italian
Ministry of Heritage and Culture for granting permission to excavate. Fieldwork and laboratory analyses are

Nora : alcune osservazioni sulla città e sul territorio nel V sec. a.C.
No full textRecent studies and excavations at the site of Nora in southern Sardinia have shown that the settlement expanded during the 5th century BC and underwent a complex process of urbanisation. The excavations in the area of the so-called"Colle di Tanit" show very clearly that the city of Nora was laid out in the late 5th century according to a coherent urban plan. In addition, a pedestrian survey carried out in the hinterland has provided data for research into the relationship between the city and the countryside during the Punic period. Taking into account the data from both the settlement and the hinterland, as well as traditional research on the role of Carthage in shaping the landscape of Sardinia, the aim of this paper is to explore the effective involvement of the African city in the urbanisation process and the regional dynamics of Nora and its hinterland
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
