Towards an Energy Politics In‐Against‐and‐Beyond the State: Berlin's Struggle for Energy Democracy

Social movements in struggle around energy are currently developing an imaginary of “energy democracy” to signify the emancipatory energy transitions they desire. Deploying a scholar‐activist perspective, this paper contributes to debates around the concretisation of the energy democracy imaginary by exploring the relationship of energy democracy movements to the state. To do so, I focus on the experiences of the Berliner Energietisch campaign, which in 2013 forced (and lost) a referendum aiming to extend—and democratise—the local state's role in Berlin's energy governance. Drawing on relational theories of the state, I argue that it is productive to read Berliner Energietisch as enacting an energy politics in‐against‐and‐beyond the state. In making this argument, I draw out implications for theoretical and strategic debates around the commons and the state.     

Manliness,Male Virtue and History Writing at the Seventeenth‐Century Ottoman Court

When one compares Ottoman chronicles written in the wake of the failed Vienna campaign of 1683 to those composed prior to 1682 and finally to those completed in 1658 one finds, first, that gendered conceptions were central to the authors' depictions of the era and, second, that the model of manliness and male virtue that the authors conceived changed greatly. To authors writing during the first decade of Mehmed IV's reign (1648–58), male virtue was expressed in self‐mastery, the mastery of subordinates, particularly women, and the control of financial resources. Authors in the period between 1658 and 1682 imagined manliness in terms of bravery – manifested in hunting and waging war, labelled interchangeably ghaza or jihad – and Islamic zeal. After 1682, writers again returned to an understanding of male virtue and manliness centred on self‐control. This article explains the reasons for this change in conceptions of manliness and male virtue by relating it to the dynamic competition between courtly factions patronising literary production. The need to curry favour with these factions was reflected in the writers' choice of literary genre, which intervened discursively to offer different images of the sultan and valide sultan (queen mother).     

ANALYSING ARCHAEOLOGICAL BASALT USING NON‐DESTRUCTIVE ENERGY‐DISPERSIVE X‐RAY FLUORESCENCE (EDXRF): EFFECTS OF POST‐DEPOSITIONAL CHEMICAL WEATHERING AND SAMPLE SIZE ON ANALYTICAL PRECISION*

Energy‐dispersive X‐ray fluorescence (EDXRF) has been commonly used to determine geological sources of volcanic glass artefacts, but its ability to discriminate between basaltic sources is less developed. We examine the precision and accuracy of non‐destructive EDXRF for basalt artefacts by analysing varying size and weathering characteristics. The experiments identified no appreciable effect in reproducibility or measured composition due to thickness (down to 1 mm) or natural weathering of pre‐contact flake scars for the 17 elements measured in this study. Samples with surface area less than 100 mm², however, show significant variability in measured composition and reproducibility.     

The 9th‐Century‐AD Belitung Wreck,Indonesia: analysis of a resin lump

The 9th‐century‐AD Belitung wreck was discovered in 1998 in the Java Sea. Construction techniques rapidly confirmed that it was unlike any known Chinese or Southeast Asian vessel. The uncertainty about its origins was resolved in 2008 by timber identifications: it was constructed in the Middle East (probably Oman or Yemen). This paper, on the characterization of a dammar resin lump collected in the vicinity of the wreck, supplies additional evidence confirming the probable re‐stitching of the vessel somewhere in Asia. © 2010 The Authors     

Post‐CO2 injection alteration of the pore network and intrinsic permeability tensor for a Permo‐Triassic sandstone

The aim of this study was to determine the process–structure–property relationships between the pre‐ and post‐CO₂ injection pore network geometry and the intrinsic permeability tensor for samples of core from low‐permeability Lower Triassic Sherwood Sandstone, UK. Samples were characterised using SEM‐EDS, XRD, MIP, XRCT and a triaxial permeability cell both before and after a three‐month continuous‐flow experiment using acidic CO₂‐rich saline fluid. The change in flow properties was compared to those predicted by pore‐scale numerical modelling using an implicit finite volume solution to the Navier–Stokes equations. Mass loss and increased secondary porosity appeared to occur primarily due to dissolution of intergranular cements and K‐feldspar grains, with some associated loss of clay, carbonate and mudstone clasts. This resulted in a bulk porosity increase from 18 to 25% and caused a reduction in mean diameter of mineral grains with an increase in apparent pore wall roughness, where the fractal dimension, D_f, increased from 1.68 to 1.84. All significant dissolution mass loss occurred in pores above c. 100 μm mean diameter. Relative dilation of post‐treatment pore area appeared to increase in relation to initial pore area, suggesting that the rate of dissolution mass loss had a positive relationship with fluid flow velocity; that is, critical flow pathways are preferentially widened. Variation in packing density within sedimentary planes (occurring at cm‐scale along the ‐z plane) caused the intrinsic permeability tensor to vary by more than a factor of ten. The bulk permeability tensor is anisotropic having almost equal value in ‐z and ‐y planes but with a 68% higher value in the ‐x plane (parallel to sedimentary bedding planes) for the pretreated sample, reducing to only 30% higher for the post‐treated sample. The intrinsic permeability of the post‐treatment sample increased by one order of magnitude and showed very close agreement between the modelled and experimental results.     

The contentious politics of nationalism and the anti‐naturalization campaign in Tunisia, 1932–1933

This article asks how, when, and why people came to mobilize en masse in the name of the Tunisian nation against French Protectorate rule. Rather than taking anti‐colonial nationalism as an inevitable response to the imposition of colonial rule, the account offered here insists that it is an outcome to be explained. Building on more recent theoretical directions that stress the processual, relational, and eventful dynamics of nationalism, the article shows that nationalism and nationalist mobilization cannot be attributed simply to the workings of nationalist intellectuals, to long‐standing grievances, or to larger macro‐level transformations. Rather, seeing nationalism as part of struggle and as a domain in which various forms of contentious politics are played out, I show how attention to a particular contentious event in the anti‐naturalization campaign can help us to understand how a certain version of the nation becomes salient as a mobilizing rubric for mass‐level mobilization and how various forms of contention coalesce to produce nationalist outcomes.     

Plastic arts and nation‐building in Israel

This article begins as an attempt to analyse an apparently paradoxical situation created by two events, which occurred simultaneously in 1948: the establishment of Israel as an independent state and the emergence of the Ofakim Hadashim (New Horizons) group of artists, acknowledged as the most renowned local artists at the time. The creation of the state of Israel may be considered the high point of Jewish nationalism, when the nation celebrated its distinctiveness. On the other hand, Ofakim Hadashim was a group of intellectuals who aspired to disengage their artistic work from the dominant political processes of the time. The basic claim of its members was l'art pour l'art, which ostensibly contradicted the significance of the general political process. This situation is highly interesting since it challenges the general sociological assumptions about the role of intellectuals in nation‐building processes, and also contradicts the usual explanation regarding the Israeli state‐building process. It concludes that an explanation of the social complexity existing in 1948 can be found in an understanding of modernity as a multifaceted phenomenon embracing a diversity of inherently contradictory practices.     

Scholarly Authority and Lay Mobilization: Yusuf al‐Qaradawi's vision of da‘wa, 1976‐1984

The late 1970s and early 1980s were a propitious yet challenging time for the Muslim Brotherhood in Egypt, as its elites sought to define the movement's priorities in the face of new opportunities to spread their call (da‘wa). The debate over preaching, while one of strategic assessment, also involved a negotiation of intellectual hierarchy: Should laymen lead Egypt's oldest Islamist organization, or should scholars? In contrast to previous studies that focus on how laymen led the Brotherhood's return to grassroots preaching, this article reintegrates scholars into the story of da‘wa by focusing on the organization's most prominent ‘ālim, Shaykh Yusuf al‐Qaradawi, and his vision of institution‐based preacher education and extra‐institutional activism. Drawing on three books written by Qaradawi on this topic between the mid‐1970s and early 1980s, this article casts lights not only on this Islamist scholar's claim to religious authority as he sought to mold the Brotherhood, but also on the ways in which projects of mass mobilization – whether grassroots preaching or the reform of state‐sponsored educational curricula – have transformed scholarly claims to authority more broadly.     

ARCHAEOMAGNETISM IN ARCHAEOMETRY— A SEMI‐CENTENNIAL REVIEW*

The journal Archaeometry and its first co‐editor Martin Aitken played key roles in the development of archaeomagnetism. This paper briefly reviews all papers published in Archaeometry, and a few others, dealing with archaeomagnetic secular variation, archaeomagnetic dating, archaeointensity studies and related applications of magnetic studies to archaeology, to indicate some of the major developments over the past 50 years.     

The p‐Regions Problem. p‐区域问题

The p‐regions problem involves the aggregation or clustering of n small areas into p spatially contiguous regions while optimizing some criteria. The main objective of this article is to explore possible avenues for formulating this problem as a mixed integer‐programming (MIP) problem. The critical issue in formulating this problem is to ensure that each region is a spatially contiguous cluster of small areas. We introduce three MIP models for solving the p regions problem. Each model minimizes the sum of dissimilarities between all pairs of areas within each region while guaranteeing contiguity. Three strategies designed to ensure contiguity are presented: (1) an adaptation of the Miller, Tucker, and Zemlin tour‐breaking constraints developed for the traveling salesman problem; (2) the use of ordered‐area assignment variables based upon an extension of an approach by Cova and Church for the geographical site design problem; and (3) the use of flow constraints based upon an extension of work by Shirabe. We test the efficacy of each formulation as well as specify a strategy to reduce overall problem size.     

Organic–inorganic rock–fluid interactions in stylolitic micro‐environments of carbonate rocks: a FIB‐TEM study combined with a hydrogeochemical modelling approach

Stylolites and the interfaces to the host limestone have been investigated by means of a multidisciplinary analytical approach (thin section microscopy, FIB‐TEM, organic geochemistry and petrography). Carbonate dissolution assuming different boundary conditions was simulated by applying a generic hydrogeochemical modelling approach. It is the conceptual approach to characterize and quantify traceable organic–inorganic interactions in stylolites dependent on organic matter type and its thermal maturity, and to follow stylolite formation in carbonates as result of organic matter reactivity rather than pressure solution as a main control. The investigated stylolite samples are of Upper Permian (Lopingian, Zechstein), Middle Triassic (Muschelkalk) and Late Cretaceous (Maastrichtian) age and always contain marine organic matter. The thermal maturity of the organic matter ranges from the pre‐oil generation zone (0.4–0.5% R_r) to the stage of dry gas generation (>1.3% R_r). The results of the generic hydrogeochemical modelling indicate a sharp increase of calcite dissolution and the beginning of stylolite formation at approximately 40°C, which is equivalent to a depth of less than 800 m under hydrostatic conditions considering a geothermal gradient of 30°C and a surface mean temperature of 20°C. This temperature corresponds to the pre‐oil window when kerogens release an aqueous fluid enriched in carbon dioxide and organic acids. This aqueous fluid may change the existing pore water pH or alkalinity and causes dissolution of carbonate, feldspar and quartz, and clay mineral precipitation along the stylolite. Dissolution of limestone and dolostone leads to reprecipitation of calcite or dolomite opposite of the dissolution side, which indicates only localized mass redistribution. All these integrated hydrogeochemical processes are coupled to the generation of water during organic matter maturation. In all of the calculated hydrogeochemical scenarios, H₂O is a reaction product and its formation supports the suggested hypothesis.     

Morgawr: an experimental Bronze Age‐type sewn‐plank craft based on the Ferriby boats

This paper reports on the construction of a full‐scale Bronze Age‐type sewn‐plank boat based on the Ferriby boats. The boat, which was named Morgawr, was constructed in the National Maritime Museum Cornwall in Falmouth, England, during 2012 and the first months of 2013, as part of a larger exhibition in the museum. This paper provides the background and context of the project, describes the process of building the craft, and reflects in particular on differences between Morgawr and the ‘hypothetical reconstruction of a complete sewn‐plank boat’ published in 1990 by Ted Wright and John Coates which formed the basis for this project.     

Historicizing Edai Siabo: a Contemporary Argument about the Pre‐colonial Past among the Motu‐Koita of Papua New Guinea

ABSTRACT In the 1970s the Motu‐Koita, traditional inhabitants of what is now the National Capital District of Papua New Guinea, inaugurated a yearly cultural festival thematically based on traditional coastal trading voyages known as hiri. Contestation over the location and commercialization of the festival in the capital city developed in the new century as one distant village claimed to ‘own’ the hiri. The Motu‐Koita view of their past and their identity has been affected by their encounter with Christianity, colonialism and its aftermath, and the rhetoric of the villagers’ claims drew on criteria of authenticity, cultural purity, and exclusiveness which are arguably contemporary rather than ‘traditional’. This article reviews Motu‐Koita history, the story of the origin of the hiri, and the local politics of the cultural festival. It attempts to understand the way the past, which was formerly mythopoeically invoked, is being historicized and thereby fixed in new local discourses of cultural and heritage rights and ownership, as Melanesians come to terms with the effects of global processes on their traditions and other resources.     

AN 8500‐YEAR‐OLD BLADDER STONE FROM UZZO CAVE (TRAPANI): FOURIER TRANSFORM–INFRARED SPECTROSCOPY ANALYSIS*

A calcium carbonate (calcite) bladder calculus was found in the pelvis of an adult female buried in a Mesolithic cave‐tomb on the coast of Sicily; it was dated by ¹⁴ C to around 6500 bc . Its chemical composition, which was not known before, was determined by means of Fourier transform–infared microspectroscopy (FT–IR–M) using the high‐pressure diamond cell, a device that makes it possible to analyse a small amount of the sample (1–2 µg). In this way, the analysis of all the laminations of the calculus was performed without destroying the sample. Although calcite was the main component, carbonate apatite was also detected in the nucleus and in a more external layer.     

Post‐Conflict Ambon: Forced Migration and the Ethno‐Territorial Effects of Customary Tenure

In post‐conflict contexts characterized by large‐scale migration and increasing levels of legal pluralism, customary land tenure risks being deployed as a tool of ethno‐territorialization in which displaced communities are denied return and secure land rights. This thesis will be illustrated through a case study of the Indonesian island of Ambon where a recognition of customary tenure — also called adat — was initiated in 2005 at the end of a high‐intensity conflict between Christians and Muslims. Although a system of land tenure providing multiple forms of social security for the indigenous in‐group, adat in Ambon also constitutes an arena of power in which populations considered as non‐indigenous to a fixed historical territory are pushed into an inferior legal position. The legal registration of customary tenure therefore tends to be deployed to settle long‐standing land contests with a growing migrant community, hereby legally enforcing some of the forced expulsions that were brought about by the recent communal violence.
