In the Iberian Peninsula, the copper metallurgy from the Chalcolithic to the Middle Bronze Age (MBA) was mostly characterized by low arsenic contents. A collection of 53 MBA artefacts from southern Portugal was analysed by micro‐EDXRF, optical microscopy, SEM–EDS and Vickers to investigate the metal composition and manufacture. No technological distinction was found between artefacts from domestic and funerary contexts, which were radiocarbon‐dated to 2000–1500 cal bc . The arsenic contents of almost 100 MBA artefacts from this region, including the above‐mentioned set, have a Gaussian distribution with a high average (3.9 wt% As). Possible explanations are discussed for this distinctive metallurgy at the south‐western end of the Iberian Peninsula. 相似文献

Bayesian statistics has now demonstrated its strong utility in archaeology, specifically through software that conditions radiocarbon data. Only recently has this technology been applied within Maya archaeology, however, in part because the Maya calendar provides a much greater resolution in dating archaeological events than is possible with radiocarbon data. The Long Count in particular allows for the assignment of some events relative to each other, accurate to the day. In this paper, a new approach is presented to incorporate robust records of both in the same Bayesian analysis through the OxCal software. The results do call for a reconsideration of the earliest radiocarbon studies in the Maya area from the 1960s, as well as the latest attempts to corroborate the currently popular calendar correlation known as the GMT. This new study demonstrates the value of the approach and corroborates the 1σ accuracy of the GMT, while at the same time opening up the possibility of revision by 20 or more years. 相似文献

The grounds of 51 post‐Byzantine icons (Eastern Orthodox panel paintings) were studied by means of analytical techniques. The artefacts cover the period from the mid‐15th to the mid‐19th century and originate mainly from western (Epirus and the Ionian Islands) and southern Greece (Crete). The findings are examined in the light of technical recipes from related areas and eras, while special insights are gained from the exploration of a gypsum processing recipe by Dionysius of Fourna. A spectrum of ground fabrication practices that is richer than that reported so far or can be deduced from surviving Greek recipes is documented; three instances of ‘grosso‐sottile’ type grounds and a case of ‘inverse grosso‐sottile’ ground are among the reported novel, for post‐Byzantine icons, findings. Moreover, a case of an early icon restoration intervention is documented. 相似文献

In 1665, Robert Hooke published his major work in microscopy, Micrographia, a defense of experimental philosophy. The following year, Margaret Cavendish, Duchess of Newcastle, published at her own expense a treatise and a novel that undermined the basis of this new science. The dispute broke out at the initiative of the Duchess, in the context of a vast controversy about the legitimacy and the efficiency of optical instruments in natural philosophy. All the figures of the dual are used, except one: the counterattack. Cavendish, indeed, was alone on the battlefield. Is it possible to call a dual a battle with only one combatant? This particular case of dispute that stops owing to the shortage of combatants is the subject of this article. 相似文献

AbstractEver since Jimmy Rabbitte proffered his oft-quoted “niggers of Europe” line in Roddy Doyle’s The Commitments (1987), contemporary Irish culture, especially during the boom years, was characterised by an insistent revisiting of popular music as a metaphor for interracial and/or intercultural connection or understanding. Cross-cultural identification through music may be seen, in Werner Sollors’s memorable terms, as an eschewing of “descent” relations in favour of “consensual” relations. This essay revisits the music metaphor as it has manifested itself in Irish fiction since it was announced officially that Ireland had entered recession in 2008. Specifically, it explores Kevin Curran’s Beatsploitation (2012) and Joseph O’Connor’s The Thrill of It All (2014) arguing that, through their deployment of the music metaphor, the novels stage the murky politics of contemporary Irish iterations of consent and descent. By exposing the extent to which the rhetoric of Irish economic recovery is yoked to paradoxical invocations of volitional and ancestral Irishness, the novels urge their readers to consider the ways in which discourses of economic recovery work to reinforce and perpetuate patterns of exclusion and marginalisation established during the Celtic Tiger years. 相似文献

Wright, A.J., Plusquellec, Y. &; Gourvennec, R., February 2016. Devonian operculate corals (Calceolidae, Cnidaria) from the Massif Armoricain, France. Alcheringa 40, xxx–xxx. ISSN 0311-5518The operculate coral Calceola gervillei Bayle, 1878 is described for the first time on the basis of the type material from the Cotentin region of Normandy (North Armorican Domain), from Early Devonian (likely upper Lochkovian to lower Pragian) strata, and is chosen as the type species of the monotypic new genus Gerviphyllum. The new genus is also present in the l’Armorique Formation (lower Pragian) of the Plougastel Peninsula (Central Armorican Domain) as Gerviphyllum sp. cf. G. gervillei. One locality in the upper Emsian (Polygnathus serotinus Conodont Zone) Le Fret Formation, on the northern coast of the Crozon Peninsula, has yielded operculate coral specimens described here as ?Chakeola sp., the first (tentative) record of the genus outside eastern Australia, south China and Vietnam. The operculate coral Calceola collini sp. nov. is described from six localities in the early Middle Devonian (Eifelian: Polygnathus costatus Conodont Zone) Saint-Fiacre Formation of the Plougastel and Crozon Peninsulas (Central Armorican Domain), despite the fact that knowledge of the internal characters, especially of the operculum, of the type species Calceola sandalina is very limited. From an extensive review of published references to Calceola from France, we conclude that only the record of Collin (1929) is valid.Anthony Wright (tony. wright@optusnet. com. au), GeoQuEST Research Centre, School of Earth &; Environmental Sciences, University of Wollongong, Wollongong, NSW, 2522, Australia; Yves Plusquellec (yves. plusquellec@univ-brest. fr) and Rémy Gourvennec (remy. gourvennec@univ-brest. fr), Université de Bretagne Occidentale, CNRS-UMR 6538 ‘Domaines océaniques’, Laboratoire de Paléontologie, UFR Sciences et Techniques, 6 avenue Le Gorgeu, CS 98837, F-29283, Brest, France.

Intersectionality is a complex concept to deal with when doing research but also when teaching the interrelationships between space and social relations. Here we present “Relief Maps” as a visual tool for teaching intersectionality and its spatial dimension in higher education courses. “Relief Maps” are a model developed for research and applied in a Geography and Gender course at the Universitat Autònoma de Barcelona (UAB) with the aim of promoting student reflection on the relationships between power structures, places and lived experiences, starting from their everyday lives. 相似文献
