The role of arsenic in Chalcolithic copper artefacts – insights from Vila Nova de São Pedro (Portugal)

The Castro of Vila Nova de São Pedro (VNSP) is an emblematic settlement located at Azambuja, Portuguese Estremadura. It was occupied during the third and second millennia BC, predominantly during the Chalcolithic period. A diversified collection of 53 copper-based artefacts (most part in a fragmentary condition), belonging to an extensive metallic collection recovered during excavations carried out in VNSP, was studied using micro-EDXRF spectrometry, optical microscopy and SEM-EDS. Additionally, Vickers microhardness measurements were performed to establish the effectiveness of the thermomechanical treatment in the hardness of the artefacts. Results show that the Largo do Carmo, artefact collection is mainly composed of copper or arsenical copper, being 37% of the artefacts made of copper alloyed with arsenic (As > 2%). A statistically significant association was found between copper alloyed with arsenic and artefacts classified as tools/weapons (arrowheads, daggers and knives). In several cases, the presence of arsenic rich phases in the microstructure, resulting from an inverse segregation phenomenon, shows no evidence of chemical homogeneity control during the artefact manufacture. Microstructural analyses also show that the majority of this group (73%) was shaped with forging plus annealing operation cycles and 23% of the artefacts received a final cold hammering after the forging and annealing. An association between the presence of a final forging treatment and artefacts presenting higher arsenic contents was also identified. Nevertheless, no direct correlation was found between the arsenic content of the alloy and its hardness. Also no direct correlation was found between the hardness and a final forging operation. However, it was observed that a harder forging was applied to the cutting edge of the artefacts and consequently a high hardness in this area was obtained despite the arsenic content of the alloy. Concerning arsenical copper alloys, all evidences point out that the potential for obtaining a harder material was not recognized by the ancient metallurgists and the selection of the alloy was possibly made based on colour.     

Microanalytical study of copper ores from the Chalcolithic settlement of São Pedro (Portugal): Copper production in the south-western Iberian Peninsula

Copper ores recovered at the third millennium bce settlement of São Pedro, Portugal, were characterized by micro-Raman spectroscopy, micro-energy dispersive X-ray spectrometry (micro-EDXRF) and micro-particle-induced X-ray emission spectrometry (micro-PIXE). The collection shows the common presence of secondary copper minerals (malachite, pseudomalachite and libethenite) combined with iron oxyhydroxides (hematite and goethite), while arsenic-rich minerals are absent and, therefore, can be excluded as the source of arsenical copper. Overall, these copper ores suggest a primitive technology involving the exploitation of the superficial zone of ore bodies and reliant on the fortuitous finding of arsenic-rich sources to produce the arsenical copper alloy frequently present among metallic collections of the Iberian Peninsula.     

The Emirate of Córdoba (756–929 AD) and the introduction of the Egyptian mongoose (Herpestes ichneumon) in Iberia: the remains from Muge,Portugal

We describe new finds of Herpestes ichneumon (Egyptian mongoose) from an archaeological context in Portugal, directly ¹⁴C dated to c. 800 AD. This is at least two centuries older than a previously reported find of this species from Andalusia (southern Spain; Riquelme-Cantal et al., 2008). Our finding provides further support to the hypothesis that the Muslims introduced this animal to the Iberian Peninsula. In particular, we suggest that Berber settlers might have brought it some time during the Umayyad conquest of Iberia or with the establishment of the Emirate of Córdoba.     

Who does the work in sustainable households? A time and gender analysis in New South Wales,Australia

Households in the affluent West have become an important target of government and NGO campaigns to encourage more environmentally sustainable behaviours, but there has been little research into the gender implications of such policies. This article investigates the role of gender and time in the sustainability practices of six heterosexual households with young children, committed participants in the Sustainable Illawarra Super Challenge programme in 2009. Women spent more total time on sustainable practices, and did so more often. Men's contributions related mostly to gardening and transport, in longer blocks of time. In these households, sustainability became a highly gendered practice because of the different roles in homemaking. Women resisted constructions of themselves as being closer to nature, and shouldered expectations of sustainability as part of their roles as mothers and household managers. They experienced time as overlapping and fragmented, with no distinction between work and leisure. Men contributed to sustainable practices mainly through activities understood as leisure, in longer blocks of time. Our temporality lens also illustrates the gendered ways that old practices become deroutinised and new practices reroutinised. While men were often responsible for the labour and upfront time required to start or research a project, the responsibility of everyday implementation and habit-changing commonly fell to women. These findings illustrate how gendered analyses help identify both opportunities for, and constraints against, change towards sustainability. Opportunities include the strong connections between both mothers' and fathers' understanding of good parenting and the importance they attach to household sustainability. Constraints include the temporal challenges faced by households, and how these interact with wider structural and labour roles.     

To the barracks: the President,the military and democratic consolidation in Portugal (1976–1980)

After two turbulent years in which different pathways for the future of the political and institutional framework of Portugal clashed, the country began a process of consolidation of the democratic institutions delineated between 1975/6. However, the role played by the military in the fall of the previous dictatorial regime and the fragility of the new democratic institutions did not allow their immediate withdrawal from political life. The President of the Republic was a military man and the political parties had agreed to maintain an unelected sovereign body, the Council of the Revolution, which only dissolved in 1982. Based on primary sources that only recently became available, this article presents some elements that help to understand the success of democratic consolidation in Portugal. This long process should not be interpreted as a confrontation between civilians, desirous to put an end to military tutelage, and the military, who at all costs sought to keep their privileges. The dividing line should be placed between those who defended the maintenance of the status quo, and the supporters of military subordination to the civil power.     

The kingdom of Portugal,homage and papal ‘fiefdom’ in the second half of the twelfth Century

This paper examines the relationship between the newly formed kingdom of Portugal and the papacy in the second half of the twelfth century. The kings of Portugal sought a close alliance with the papacy and their relationship has been seen as that of ‘vassal’ and overlord. However, it seems likely that this alliance owed more to the tradition of monastic protection grants. The act of homage performed to the papal legate by King Afonso I is an example of a wider use of the homage ceremony. Homage was not only used to cement ‘feudal’ bonds, but also to make peace or to confirm pacts and agreements. The annual census paid by the kingdom to Rome was part of the same grant of protectio. The papal–Portuguese letters used the same language and terminology as ecclesiastical protectio, which was awarded by the papacy to monasteries, churches and eventually kingdoms and kings.     

How the News was brought from Byzantium to Angoulême; or,The Pursuit of a Hare in an Ox Cart

Abstract

Adémar of Chabannes (988-1034) of noble family, a-monk in the monastery of St. Cybard (Eparchus) at Angoulême, compiled a Chronicon in three books. The first begins with the origins of the Franks and ends with the death of Pepin the Short in 768; the second deals with the reign of Charlemagne; the third covers the years 814 to 1030. The first two books and the first fifteen chapters of the third (down to the year 877) are wholly derivative from identifiable sources. But from chapter sixteen onward the third book provides valuable information chiefly on the period 877-1030 in Aquitaine, presumably drawn from local written sources and from the memories of Adémar's associates. These included notably his two uncles, who were attached to the monastery of St. Martial at Limoges, as was Adémar himself in his youth. It was at St. Martial that on a stormy night in 1010 Adémar had a vision in the heavens of a fiery Cross with Christ upon it weeping a great river of tears: an experience that rendered him so thunderstruck (attonitus) that he kept it secret in his heart until many years later when he was nearing the end of his Chronicon. Then he wrote it down. From St. Martial he returned at the age of twenty-two to St. Cybard, took orders, and spent his life in writing. The‘original’chapters of his Chronicon only occasionally evince any interest in or knowledge of events in France north of Loire.     

Who Knew the Minds of the People? Specialist Knowledge and Developmentalist Authoritarianism in Postcolonial Ghana

By the mid-1960s, local-level development workers in Ghana were expected to act as the eyes and ears of the state, reporting on ‘the minds of the people’ and explaining their reactions to President Kwame Nkrumah's project of socialist reconstruction. This articles argues that through mass education, social welfare and community development plans, both the late colonial and early independent state sought to make its presence manifest in the everyday lives of its citizens, to bind them to a broader vision for their country, and to present their successes to the outside world. By identifying some of the competing models of social development that were promoted by British, Ghanaian and African-American experts in the aftermath of independence, this article investigates the role of specialist knowledge in the developmentalist authoritarianism which is often presented as a generic legacy of the colonial state in Africa.     

The Colonial (Dis)order and the (Im)possibility of Redemption: Jeong,Abolition, and Living from the “End of the World”

This article develops the oppositional edge of postcolonial theologies by way of Frantz Fanon’s anti-colonial desire for the “end of the world.” It connects W. Anne Joh’s elaboration of jeong – the living in excess of (neo)colonial violence – to Dietrich Bonhoeffer’s anti-fascist critique of the godlike desires of European humanism (the sicut deus). The overall aim of the article is to clarify and assess what is at stake in a project of eschatological decolonialism. What might it mean to think theologically about salvation as abolition? And what might it look like to live from the “end of the world?”     

Harvesting molluscs in the Eneolithic: a study of freshwater bivalve accumulations from the tell settlements of Borduşani-Popină and Hârşova (Romania, 5th millennium BC)

Freshwater bivalve shells are frequently identified in faunal assemblages from Neo-Eneolithic tell settlements along the Danube River valley in South-East Romania (5th millennium BC). Up until now, significant accumulations of freshwater bivalve shells have been identified only in household refuse areas of the settlements, where they form consistent shell layers. The origin and formation of such shell accumulations and, more generally, the role of bivalves in the animal economy of the prehistoric populations that inhabited the settlements, are poorly understood. Two freshwater bivalve shell accumulations were studied in household refuse areas of Eneolithic tell settlements, one at Bordu?ani-Popin? and the other at Hâr?ova tell. The occurrence of similar accumulations in the two settlements indicates generalized practices between the two communities. This first study of such accumulations addresses the relationship between bivalves and other animal species used in alimentation by the two Eneolithic communities, as well as the relationships between these communities, their environment, and the evolution of the settlements. Bivalves were harvested in the close vicinity of the settlements and large quantities were obtained only towards the end of the summer season. During this season there is an inverse relationship between high water levels in the river and the availability of bivalves for harvesting. Bivalves played an important role in the alimentation of the prehistoric populations – at Hâr?ova tell their contribution to alimentation in terms of energetic yield surpasses that of fish, at least for the short period of time represented by the stratigraphic sequence analysed. Bivalve shells were used, along with other types of household refuse, in construction techniques aimed at limiting soil humidity in the settlements and inside the dwellings.     

Who cut the ribbon? A quantitative analysis of formal opening ceremonies of new plants of multinational corporations in Russia

This paper reports on a study of formal opening ceremonies of new plants of multinational corporations in Russia. We argue that such ceremonies have profound symbolic meanings, namely managing anxiety and signaling commitment, as well as practical importance, particularly when top executives of corporate parents meet with top officials from the host countries at such ceremonies. The database embraces the entire population of public opening ceremonies of new plants of western multinational corporations (MNCs) in Russia from 2012 to 2016. The analysis revealed that in 2016, the unwillingness of both corporate CEOs and local governors to participate in plant opening ceremonies began to increase. More than one-third of plant opening ceremonies in 2016 were low-profile ceremonies ignored by top officials from corporate parents and local authorities from the host country. The growing absence of local governors is attributed to the smaller size of newly opened plants and the impact of sanctions imposed on Russia by the United States and European Union following the inclusion of Crimea into Russia in 2014. This paper also indicates a promising direction for further studies – a replication study that should embrace public opening ceremonies of new plants of foreign MNCs in China, India, and Brazil.     

Who owns the past? A perspective from Chiang Saen,Thailand

Abstract

Chiang Saen is an early Buddhist community in northern Thailand, dating from the fourteenth century. It is regarded as an important historic site and, therefore, as deserving of preservation and protection. A preservation plan for this ancient town, proposed by the Thai Fine Arts Department, has been in operation since 1957. Forty years of attempts to develop the site have seen profound differences in attitude between local people and the government archaeologists and technicians. Problems such as looting, damage to and deterioration of the ruins, and site encroachment have hampered heritage management in the area. Research on the management of the site was conducted in summer 1996 and winter 1997, revealing a number of reasons why this well-intended preservation project has met difficulties. The problems encountered revolve around the question: Who owns the past?'. Government officials conducting CRM work at the site often blame local people for not cooperating with an 'official government project', and for failing to understand the informational value of the site. Local people take a different view: they understand that the site and/or archaeological remains found there belong to the government, so they believe it is the government's responsibility to take care of them. They do not feel a sense of ownership for the cultural property. Interviews with local people suggest that public education and interpretation must be taken seriously. Local people are ready and willing to help if they feel they have a stake in the CRM programme. Any possible cooperation and assistance from the residents lies in the government's ability to answer the question of ownership of the past in a way that includes local people.     

Who Pays the Ferryman? Industry Policy and Shipbuilding in Australia

The lightweight fast ferry industry that has emerged in Australia over the last couple of decades has been a remarkable and surprising success story. Given the contraction of manufacturing in general and traditional shipbuilding in particular, its growth is all the more noteworthy. This paper analyses the evolution of the industry and considers the impact of industry policy on its development. Although the effectiveness of industry policy in Australia has generally been undermined by a lack of political support and inadequate integration with other government policies, it was, nevertheless, an important part of this industry's expansion.     

Multi-method (TL and OSL), multi-material (quartz and flint) dating of the Mousterian site of Roc de Marsal (Dordogne,France): correlating Neanderthal occupations with the climatic variability of MIS 5–3

Roc de Marsal has yielded numerous remains of Mousterian occupations, including lithics, fauna and combustion features. It was made famous by the discovery of the skeleton of a Neanderthal child. Given the need to date the sequence, TL and OSL were applied on heated flints and quartz, and OSL on unheated quartz. Chronological results combined with palaeoenvironmental data – faunal remains and micromorphological features in the sediments from the cave, pollen proxies and faunal remains from the region – allowed us to place climate variations in southwest France on a numerical time scale. Denticulate Mousterian occupations were dated to the middle of MIS 4 (65–70 ka) and Quina layers either to the very end of MIS 4 or to MIS 3. Interestingly, a faunal pattern showing a mix of red deer, roe deer and reindeer was found to have occurred during MIS 4, which was shown to be consistent with data from other similar sites in southwest France.     

Who Shapes the Politics of Expertise? Co-Production and Authoritative Knowledge in Thailand's Political Forests

Expert environmental knowledge has often been described as a governmental rationality that reduces political debate and facilitates state control. In this paper, I argue instead that this line of reasoning simplifies how knowledge gains political authority, especially when expertise is shared and left unchallenged by diverse actors, including those in conflict with each other. Using the framework of co-production from Science and Technology Studies (STS), I apply this argument to conflicts over the supposed watershed functions of forests in Thailand, where simplified narratives about the impacts of land use on water supply are used as justifications for territorialisation and restrictions on forest land. In particular, I focus on local resistance to the proposed Kaeng Sua Ten dam in northern Thailand in order to demonstrate how protestors have deliberately reproduced formal expertise to empower themselves, but by so doing also reinforcing simplified visions of watershed science and community culture. I argue that exposing the co-production of authoritative knowledge and visions of social order offer greater opportunities for understanding the role of expertise as a political force than analysing competing assemblages based on oppositions of state-led expert knowledge and traditional local practices.     

In Defence of the Secular? Islamisation,Christians and (New) Politics in Urbane Malaysia

Besides the clarion call for a “new politics” by opposition political parties, a significant catalyst that arguably swayed Christian electoral choices in the landmark Malaysian general elections of March 2008 was the counsel by religious leaders to safeguard “the secular state”. This action was prompted by recent high profile controversial legal cases that were perceived to be a serious erosion of the freedom of religion clause guaranteed in the secularist Federal Constitution. In this essay, I not only examine the recent antecedents of this course of action but also delve into the more distant past in order to draw out how the apparently impervious categories of “religion” and “the secular” have been implicated in the structuring of social and political imaginaries in Malaysia.     

Where do charged particles enter in and exit from the magnetosphere? Some HEOS-2 measurements

The review concentrates on HEOS-2 spacecraft results in two main areas:

• 1.(1) Solar protons penetrating the magnetosphere: The picture emerging from earlier spacecraft and groundbased measurements is summarized in the light of proton trajectory computations and the theories of direct and diffusive proton entry to the polar caps. The direct in situ measurements made available through the unique positioning of HEOS-2 in the polar magnetosphere are described.
• 2.(2) The magnetopause electron layer: The HEOS-2 spacecraft has discovered an essentially permanent layer of energetic and relativistic electrons at the polar magnetopause. The properties of this layer and its response to geomagnetic and interplanetary conditions are described.

Who goes there? Science, fiction, and belonging in Antarctica

The implications of the ATS regime on Antarctica have been profound, both structuring the possibilities for states to engage Antarctica, while limiting those very engagements to those directly related to science. State-run science has in many ways solved the problem of Antarctica's resistance to capital development and provided a safe course for national rivalry. Yet science has not always been seen as the sole convener of Antarctic activity. Tracing three versions of a story of resistance to an alien invasion of the pole – John Campbell's ‘Who Goes There?’ (1935), and its two filmic remakes, Christian Nyby's The Thing From Another World (1951) and John Carpenter's The Thing (1981), in relation to Richard E. Byrd's Antarctic exploration career, this essay considers US strategies for incorporating Antarctic territory into national and global imaginaries.
