Lightening Europe: Establishing the European Synchrotron Radiation Facility (ESRF)

The European Synchrotron Radiation Facility (ESRF) was the first collaborative synchrotron radiation facility in Europe. This article chronicles and analyzes decisive events during ESRF’s foundation phase from the late 1970s to the mid-1980s and sheds light on the politics that mattered for its realization as a scientific collaboration in Europe. As part of a broader effort to chronicle the history of the ESRF, this article contributes to an enriched understanding of intergovernmental scientific cooperation in Europe in the second half of the twentieth century by drawing on so far unexplored material from the French National Archives and the German National Archive.     

The co-creation (of) culture? The case of Umeå, European Capital of Culture 2014

Culture is often promoted as crucial in efforts to achieve economic growth and social cohesion. In recent debates, greater attention has been directed at the importance of culture in creating democratic and just cities. Drawing on theories concerning participation, we study the processes of citizen participation in the creation of culture in relation to the European Capital of Culture in Umeå in Northern Sweden. The city has been praised for its focus on participation and the ‘co-creation’ of culture. We scrutinize the idea of co-creation, how it is filled with meaning by different actors, the way it is operationalized by city officials and cultural actors/practitioners and the possibilities for public participation and the power relationships at play in the city. We conclude that culture tends to be depoliticized and turned into an arena available for all on supposedly equal terms and ignores the very unequal terms on which different actors participate. It ignores how power relations affect and construct who gets to speak and be heard; that there are conflicting meanings of culture and co-creation and how power influences whose definition of culture is accepted.     

Going underground: experimental carbonization of fruiting structures under hearths

We show that carbonized fruits and seeds recovered from Middle Stone Age deposits in rock shelters are likely to have been carbonized as part of post-depositional processes. We buried indigenous South African fruits, nuts and seeds at pre-determined depths and distances from the centers of experimental fires. The cold ashes of the hearths and the sand surrounding them were subsequently excavated, using standard archaeological techniques and dry-screening. The fruiting structures from the oxidizing part of the fire were burnt to ashes, whereas those buried in sand under anoxic conditions survived in varying forms. Those buried 5 cm below the center of the fire were carbonized; those buried 10 cm below the center of the fire were dehydrated; and those 5 cm and 10 cm below the surface at the outer edge of the fire were unaffected. Size, moisture or oil content of the original fruit or seed did not appear to influence whether or not carbonization took place. Temperatures recorded 5 cm below the experimental fires suggest that the carbonization occurred at or before a maximum temperature of 328 °C, and also at lower maximum temperatures (152 °C) that were maintained for long periods. Even when the quantities of a particular wood are controlled, open fires may produce variable underground temperatures and the temperatures below ancient hearths would have been equally variable. We suggest that Cyperaceae (sedge) nutlets, the most numerous fruiting structures in the Sibudu Middle Stone Age archaeobotanical assemblage, occur in the shelter as a result of human activity, subsequent burial, and accidental carbonization when hearths were built directly above the buried nutlets.     

Overturning the alms bowl: the price of survival and the consequences for political legitimacy in Burma

The 2007 demonstrations in Burma posed the greatest threat to military rule there in almost twenty years. The involvement of thousands of monks across the country was of particular concern to the authorities as well as their threat of performing a religious boycott against them. This article traces the importance of Buddhism to the political legitimacy of rulers in Burma and examines how the authorities’ relationship with the Sangha has undergone significant changes under military rule. It compares the 2007 demonstrations with earlier protests and examines how the regime's legitimacy has suffered as a result of yet another crackdown, significantly this time against demonstrations led by the largest institution outside of the tatmadaw.     

The effects of PVAc treatment and organic solvent removal on δ13C, δ15N,and δ18O values of collagen and hydroxyapatite in a modern bone

The stable isotopic analysis of archaeological and paleontological bones has become a common method to examine questions of ecology, climate, and physiology. As researchers addressing such questions incorporate museum collections in their studies, it is necessary to understand the isotopic effects of common preservation techniques utilized in such collections to ensure the preservation of original isotopic values. This study examines the effects of PVAc glue (polyvinyl acetate) applied in acetone solution and the subsequent removal of PVAc using various organic solvents on the δ¹³C and δ¹⁵N values of extracted bone collagen, the δ¹³C and δ¹⁸O values of carbonate in bone hydroxyapatite, and the δ¹⁸O values of phosphate in hydroxyapatite. The data demonstrate that isotopic values in the collagen and phosphate are unaffected by any combination of PVAc treatment and solvent application. The carbonates show little variation in δ¹³C values, but exhibit variable δ¹⁸O values upon exposure to the PVAc solution. It is here suggested that δ¹⁸O values from carbonates in PVAc-treated bones do not retain an original isotopic value and should not be included in future studies.     

Bridewealth1 and the Autonomy of Women in Melanesia

Considering bridewealth in Melanesia from the angle of women's autonomy, in this introduction we review and analyse the various elements of this marriage practice that reveal its place in the symbolic, social and economic worlds of women. With an accent on social transformation, we discuss women's autonomy and agency in relation to the constraints that bridewealth puts on their lives, and on how they engage with it. Knowing what bridewealth is, and how the rules of reciprocity that it indexes obligate married women, the focus is on women's ability to act within these constraints or to redefine their contours, particularly with regards to economic and reproductive agency. The article, which serves also as the introduction for the special issue on bridewealth in the journal Oceania, discusses themes analysed in the collection, such as the moral prospects of bridewealth today, its relation to ‘capital’ in twenty-first century Oceania, the triad value/valuables/valuers, and the empowerment of women. It concludes with thoughts on gender inequality.     

Cultural and trade practices in Sincu Bara (Senegal): a multi-proxy investigation

The Sincu Bara site in Senegal is one of the most famous archeological sites in Western Africa. Here we present the results of a multi-proxy study that combined microscopic analyses, carbon content, stable carbon isotope (δ¹³C) and radiocarbon (¹⁴C) measurements. This investigation exhibits a chronological framework in two phases: from 400 yr AD to 650 yr AD and 650 yr AD to 900 yr AD. Furthermore, it shows that besides basic potteries, some potsherds are notable for a temper exclusively made with human-harvested C4 plants. Finally, the ¹⁴C analysis performed on the organic slip strongly indicates the use of bitumen or bitumen-derived products for red slip preparation. This suggests the establishment of trade relationships with Nigerian and/or Trans-Saharan populations as early as 400 yr AD.
