The Archaeology of El Niño Events and Other “Natural” Disasters

Archaeological research on disasters has increased substantially since Sheets's 1980 review of the topic, and with heightened media coverage and funding for the study of such events, archaeological interest will continue to grow. This paper examines how prehistorians have incorporated disasters into their research since 1980, using the literature on El Niño as an illustrative case, and assesses this work in relation to geographical approaches to disaster as well as concepts that have been developed within the new ecologies.     

In situ Measurements of Oxygen Dynamics in Unsaturated Archaeological Deposits

Oxygen is a key parameter in the degradation of archaeological material, but little is known of its dynamics in situ. In this study, 10 optical oxygen sensors placed in a 2 m deep test pit in the cultural deposits at Bryggen in Bergen have monitored oxygen concentrations every half hour for more than a year. It is shown that there is a significant spatial and temporal variation in the oxygen concentration, which is correlated to measured soil characteristics, precipitation, soil water content and degradation of organic material. In these deposits oxygen typically occurs when the air content of the soil exceeds 10–15% vol, while oxygen dissolved in infiltrating rainwater is of less importance for the supply of oxygen in the unsaturated zone.     

Electron Microprobe Analysis of 9th–12th Century Islamic Glass from Córdoba,Spain

Twenty‐six samples from domestic assemblages of 9th–12th century Córdoba were subjected to electron microprobe analysis. The results reveal two main compositional types. The first, encountered in 13 of the samples, seems to result from the combination of plant ashes with high‐impurity sand, and has some contemporary parallels from Syria and Egypt. The second type is a lead–soda–silica glass, encountered in a relatively high proportion of the glasses (11 of the 26 sampled), possibly formed by the addition of lead metal to existing glasses and with very few known parallels. These are among a very small number of results available to date on the chemical composition of glasses from medieval Spain, and the presence of a high proportion of lead–soda–silica glasses is particularly interesting, possibly indicating a technological practice unique to, or originating in, the western Muslim world.     

The European Union as a Gated Community: The Two‐faced Border and Immigration Regime of the EU

Abstract: Within the European Union, an internal liberalisation of cross‐border labour mobility for EU citizens is currently being combined with the tightening of control and management efforts at the external borders. At the same time, attempts are being made to strategically select immigrants from new member states as well as from outside the EU who will be of economic value. In this paper we argue that by implementing such protectionist and selective immigration policy, the EU has come to resemble a gated community in which the bio‐political control and management of immigration is, to a large extent, the product of fear. Often fear manifests itself in terms of fear of losing material gain, eg the anxiety of losing economic welfare or public security. More often, however, this fear relates to the entrance of the immigrant, the stranger and is, as such, associated with a fear of losing a community's self‐defined identity. These perceived threats to a community's comfort lead to the politicisation of protection, whereby the terra incognita beyond the border is justifiably neglected due to the indifference and the intentional blindness shown to the outside. Hiding in a gated community in order to protect this comfort zone and trying to exclude outsiders, ‘Others’, from the community, is not only in vain since the desire for completion of the Self can never be fulfilled, but what remains still more troublesome, is that this tendency will sustain and reproduce global inequality and segregation, both in the material as well as symbolic sense.     

Trump’s populism: lessons from Latin America

This paper compares left-wing Latin American populism with Donald Trump. Despite their different social bases and economic policies, they use a similar logic to construct politics as an antagonistic struggle between two camps. Left-wing and right-wing populists aim to rupture existing political institutions to give power to the people, yet they differ in how they construct this category. Whereas Trump used ethnic criteria to differentiate the people from three out groups – Mexicans, Muslims, and African-American militant organisations – left-wing Latin American populists used political and socio-economic criteria. Despite their democratising promises, Latin American populists like Hugo Chávez in Venezuela and Rafael Correa in Ecuador undermined democracy from within. Even though stronger institutions might protect American democracy, Trump has disfigured democracy.
