CHARACTERIZING THE SEDIMENTARY HISTORY OF CAVE DEPOSITS,USING ARCHAEOMAGNETISM AND ROCK MAGNETISM,ATAPUERCA (NORTHERN SPAIN)

We use a combination of rock magnetism (anisotropy of magnetic susceptibility, AMS) and magnetic polarity to characterize cave deposits and as a proxy for sedimentary fabric. In three localities at the Atapuerca archaeological site (Galeria, Gran Dolina and Sala de los Cíclopes), magnetic foliation (K_max/K_int) is always greater than lineation (K_int/K_min), consistent with a primary, depositional, sedimentary fabric. Our results, although preliminary, reveal a higher degree of anisotropy in autochtonous deposits compared to allochthonous deposits, possibly indicative of a higher hydrodynamic regime in the former. At two localities the magnetic lineation (K_max) defines a cluster, which is thought to be antipodal to the palaeocurrent direction. Hence we are able to retrieve palaeoflow directions in deposits that otherwise lack any other sedimentary structure. We conclude that AMS is a powerful tool for determining the hydrodynamic character of depositional environments in cave sediments at the Atapuerca archaeological site. A better understanding of the depositional environment and how sedimentation occurred allows reconstruction of the karst evolution and ultimately a better definition of human interaction with the environment.     

SHAFT‐HOLE AXES FROM SLOVENIA AND NORTH‐WESTERN CROATIA: A FIRST ARCHAEOMETRIC STUDY ON ARTEFACTS MANUFACTURED FROM META‐DOLERITES*

A group of Copper Age shaft‐hole axes from Caput Adriae (northeastern Italy, western Slovenia and northwestern Croatia) manufactured using meta‐dolerite have been analysed for major and trace elements. All the samples show magmatic textures and well recognizable relicts of primary mineralogical phases. Petrographic observations suggest an ophiolitic provenance of the protolithic source(s) while geochemical data indicate that the original magmas originated in a fore arc or pre arc tectonic setting. Strong similarity has been found with several lithotypes from the Banija Ophiolite Complex (Croatia), here indicated as the most probable source area. Considering the available archaeometric data about shaft‐hole axes found in northern Italy and Caput Adriae in comparison to those of axe blades discovered in the same area, it emerges that there is a utilization of different rock types, the source of which appears to be quite close to the discovery sites. In the investigated area the shaft‐hole axes are largely made from ophiolitic‐related rocks which are associated with copper deposits. Consequently there may have been a relation between the localization of the geological sources of shaft‐hole axes and the development of metallurgical activities.     

Bodies,Shrines, and Roads: violence, (im)mobility and displacement in Sri Lanka

In Sri Lanka, gender and national identities intersect to shape people's mobility and security in the context of conflict. This article aims to illustrate the gendered processes of identity construction in the context of competing militarised nationalisms. We contend that a feminist approach is crucial, and that gender analysis alone is insufficient. Gender cannot be considered analytically independent from nationalism or ethno‐national identities because competing Tamil and Sinhala nationalist discourses produce particular gender identities and relations. Fraught and cross‐cutting relations of gender, nation, class and location shape people's movement, safety and potential for displacement. In the conflict‐ridden areas of Sri Lanka's North and East during 1999–2000, we set out to examine relations of gender and nation within the context of conflict. Our specific aim in this article is to analyse the ways in which certain identities are performed, on one hand, and subverted through premeditated performances of national identity on the other hand. We examine these processes at three sites—shrines, roads and people's bodies. Each is a strategic site of security/insecurity, depending on one's gender and ethno‐national identity, as well as geographical location.     

Local Knowledge and Economic Realities Affecting Soil Erosion in the Rach Rat Catchment,Vietnam

Several parts of Binh Phuóc Province, southern Vietnam, suffer from degraded soils and vegetation as a result of both natural erosion of weak mud rocks and sandstones and intensive human activity, especially through land clearing for agriculture on unstable slopes, deforestation, and abandonment of poor farmland. The underlying cause of this land degradation has been the farming habits of migrants of varying ethnic groups who have settled in the area since 1980. The indigenous farming knowledge of these people and the role of that knowledge in soil erosion were examined by a series of household surveys. They enabled farming practices to be related to ground cover established from a 2002 Landsat 7 ETM (Enhanced Thematic Mapper), and erosion data from a series of erosion bridge measurements. A GIS (Geographical Information System) approach was piloted as a means of identifying areas vulnerable to erosion. This could then be combined with the understanding of farming practices to reveal the relative roles of farmer behaviour, crop cover, and slope and soil characteristics in the erosion process. Land use, local people's knowledge and economic realities are the main factors, as well as natural conditions, that drive this land degradation.     

London: Structural Continuities and Institutional Change in Water Management

This article provides a synthetic account of the historical development of London's water supply system within its wider national context, and addresses the current organizational setting of the water sector. Particular attention is paid to the post-Second World War period, which marked a transition towards integrated water management in England and Wales, a trend that has been consolidated since the 1970s. The article emphasizes the continuities and contradictions arising from the different combinations of public and private management strategies characterizing the UK water sector, and their implications for the sustainable management of water resources. It argues that there exists an in-built contradiction in the current institutional framework between the profit-oriented rationale of the private operators and the goals of efficiency, equity, and environmental sustainability pursued by the water regulators. Within this framework, it highlights the key policy issues facing the metropolitan water systems, and suggests what their most likely trajectories might be in the foreseeable future.     

Spring temperatures in the Sagehen Basin, Sierra Nevada, CA: implications for heat flow and groundwater circulation

Heat flow in the Sierra Nevada, CA, is low despite its young geologic age. We investigate the possibility that advective heat transport by groundwater flow leads to an underestimate of heat flow in the Sierras based purely on borehole measurements. Using temperature and discharge measurements at springs in Sagehen Basin, we find that groundwater removes the equivalent of approximately 20–40 mW m⁻² of geothermal heat from the basin. This is comparable with other heat flow measurements in the region and indicates that, in this basin, at least, groundwater does transport a significant amount of geothermal heat within the basin. Additionally, we use estimates of the mean residence time of water discharged at the springs along with hourly temperature records in springs to provide constraints on groundwater flow depths within the basin. An analytical model based on these constraints indicates that the heat removed by groundwater may represent 20% to >90% of the total heat flow in the basin. Without better constraints on the regional hydrogeology and the depth of circulation, we cannot determine whether the heat discharged at the springs represents a change in the mode of heat transfer, i.e. from conduction to advection at shallow depths (<100 m) or whether this is a component of heat transfer that should be added to measured conductive values. If the latter is true, and Sagehen Basin is representative of the Sierras, basal heat flow in the Sierra Nevada may be higher than previously thought.     

Blasphemy in Early Modern Sweden — An Untold Story

In early modern Sweden, blasphemy was regarded as one of the most serious crimes one could commit. It was subject to the death penalty and was termed Crimen Laesae Majestatis Diviniae– a “crime against the heavenly majesty.” In the period 1680–1789, 110 cases of blasphemy came before the Judiciary Inspectorate; these cases can be divided into the following categories: blasphemy against God, basphemy against the sacraments, deliberate assignations to the Devil, and other blasphemies. Of the 117 accused, only nine were women and a significant number were soldiers. Blasphemy could be regarded a common subgenre within an already oral military culture.
