Breaking sickles for shaping money. Testing the accuracy of weight-based fragmentation
Bronze is considered a key commodity during the European Bronze Age (BA, 2200-800BC). Recent studies have shown that, mostly during the Late Bronze Age (Late BA, 1300–800 BC), fragmented bronze objects were subjected to regulation consistent with a Pan-European weight system. This hypothesis is mostly based on statistical analyses of weights. In this article, we present the results of an experiment in which sickle replicas were broken up and the resulting fragments weighed and compared with examples attested from the BA. The purpose of the fragmentation was to obtain pieces complying with certain weight patterns similar to regularities observed in archaeological fragmented sickles and fragmented objects in general. Results of the fragmentation experiment have been compared with a statistical analysis of c. 1500 fragmented sickles from European BA hoards, concluding that archaeological and replica fragments share the same metrological characteristics. We suggest that rough weight-regulated fragmentation is possible even by persons with no metallurgical skill, and that both inaccurate and ‘unwanted’ fragments probably comprise the known archaeological examples, The article demonstrates that statistical analyses usually employed in similar research allow for detecting the existence of weight systems even in a dataset characterized by the significant presence of random values
Frontier Terramare: preliminary palaeoenvironmental reconstructions from the Terramare of Ronchi di Caorso (PC)
The Terramare of Ronchi di Caorso is an archaeological site inhabited during the Middle and Recent Bronze age
(3550–3170 BC), representing the westernmost Terramare village of the Po Plain, in northern Italy. In fact, archaeological material of both the classical Terramare production as well as more western productions were found during
excavations, demonstrating a mixture of cultures and extensive exchanges at this settlement.
Preliminary palynological analyses were performed on 20 samples, coming from the west moat of the settlement.
About 50 different pollen taxa were found, mostly belonging to non-arboreal plants (NAP). The forest cover, when
present, is mostly represented by deciduous Quercus and other elements of the mixed oakwood (Carpinus betulus,
Ostrya carpinifolia, Corylus avellana, Tilia, Fraxinus excelsior and Acer campestre). Additionally in the most recent
phases of exploitation of the site we detected the presence of hygrophilous species as Alnus and Pinus, thus suggesting a cooler condition that in the previous phases. Among NAP, plants belonging to the API (Anthropogenic Pollen
Indicators) and LPPI (Local Pastoral Pollen Indicators) groups are predominant, including especially cereals (Avena/
Triticum, Hordeum), Cichorieae and other Asteraceae, Brassicaceae and Ranunculaceae. Generally, the pollen assemblage shows an open landscape, with very low forest cover around the site, that is mostly characterised by grasslands and synanthropic communities.
Many remains of cereals (grains, fragments, glume bases, spikelets) characterise the samples studied so far from a
carpological point of view.
Among them, various species of wheat (T. monococcum, T. turgidum ssp. dicoccon, T. spelta), barley (Hordeum vulgare) and millet (Panicum miliaceum), accompanied by undetermined fragments of cultivated pulses.
Dogwood and elderberry are the food fruits attested with herbaceous and anthropogenic weeds (mainly Chenopodium, Rumex, Lysimachia).
Ash and deciduous oak are the first remains identified through the anthracological study, confirming what was reconstructed from the pollen analyses
Experiencing visible and invisible metal casting techniques in the bronze age Italy
L'articolo si concentra su aspetti legati all'archeometallurgia. Si tratta di aspetti "visibili" e cioè legati ad effettivi ritrovamenti archeologici (realizzazione di forme di fusione in pietra e processo di fusione) ma anche "invisibili" come la modalità di realizzazione di oggetti come spade in bronzo con la tecnica della fusione in sabbia
The Late Bronze age hilltop site of Monte Croce Guardia in the context of Bronze Age and Early Iron Age settlement organization in Peninsular Italy
The site of Monte Croce Guardia offers a unique opportunity to investigate the spatial organization of a Final Bronze Age settlement in peninsular Italy. Data from new excavations and geophysical surveys are presented, focusing on the distribution of identified dwellings. This distribution is explored and compared with that of coeval sites such as Sorgenti della Nova and Sovana. An organizational pattern based on groups of huts, likely related to family groups, emerges from the analysis. The described model is further compared with several settlements and buildings dating from the Bronze Age to the Early Iron Age, across continental Italy, particularly focusing on the area south of the Po river
Going Beyond Counting First Authors in Author Co-citation Analysis
The 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
“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
We 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
We 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
