Sustainable Water Management Policy: Lessons from Amsterdam

This article focuses on the identification of critical water policy instruments, and opportunities and barriers to transforming urban water use in a sustainable and efficient direction in Amsterdam (The Netherlands). The main lessons that can be inferred from past and current water policies and management practices in Amsterdam show (1) the relevance of common action for increasing the quality of or general control over water resources when shared interests of different actors using the same water resource are present; (2) that the effectiveness and applicability of water policy instruments are strongly conditional upon receiving the support of both water users and suppliers; (3) that the governance structure of water provision plays a crucial role in increasing the efficiency of water use.     

INVESTIGATION ON ROMAN LEAD GLAZE FROM CANOSA: RESULTS OF CHEMICAL ANALYSES*

Five sherds of green glazed pottery excavated at Canosa (Apulia) in Italy have been analysed by scanning electron microscopy. The aim of the investigation was to determine the chemical composition of the glazes and thus obtain information on the methods used in their production. The glazes were all of the high‐lead type, coloured green by the addition of copper. Intermediate layers, observed at the interface between the glaze and body and giving the appearance of an applied white slip, were the result of the crystallization of lead feldspar from the molten glaze. Non‐calcareous clays were used in the production of the pottery bodies. Concentration profiles from the glaze exterior to the body suggested that the glazes were produced by applying a suspension consisting of lead oxide plus silica to the bodies. On the basis of the glaze and body compositions, it is suggested that the Canosa glazed pottery was produced locally.     

4. “KEEP THAT WOMAN OUT!” NOTIONS OF SPACE IN TWENTIETH‐CENTURY FLEMISH WITCHCRAFT DISCOURSE

This article considers the importance of a spatial dimension for witchcraft research, which has so far been largely neglected. In twentieth‐century Europe people in certain regions still considered their world in terms of witchcraft; they attributed misfortune to bewitchments and usually blamed their neighbors. Here a part of Flemish‐speaking Belgium is investigated with the help of legend texts collected in the 1960s. The witchcraft discourse that informed these texts did not just contain formulations of space; sometimes it also determined how people negotiated space. In this part of Flanders, witchcraft was embedded in Roman Catholicism; monasteries were the favored destinations of all those who considered themselves or their family members bewitched. In order to find cures for bewitchments people undertook hazardous journeys of considerable distance and found their efforts hindered by the witch they sought to counteract. The measures against evil influences that they were given were meant to consolidate the boundaries between their own (private) space and the (outside) space where witches roamed. Bewitchments were generally blamed on women. In the contemporary patriarchal social order, both public and domestic spaces were nearly always under men's control. This is why bewitchment was caused less by transgressions of male‐defined boundaries than by infringements of bodily spaces such as by eying or touching somebody else's children. This suggests a different approach to female space based on notions of proximity.     

NON‐DESTRUCTIVE ANALYTIC METHOD USING XRF FOR DETERMINATION OF PROVENANCE OF ARCHAEOLOGICAL OBSIDIANS FROM THE MEDITERRANEAN AREA: A COMPARISON WITH TRADITIONAL XRF METHODS*

A non‐destructive analytical method using wavelength‐dispersive X‐ray fluorescence (WDXRF) that allows the establishment of the provenance of archaeological obsidians was developed and a comparison with the classical XRF method on powders is discussed. Representative obsidian samples of all the geological outcrops of archaeological interest of the Mediterranean area (Lipari, Pantelleria, Sardinia, Palmarola and the Greek islands of Melos and Gyali), were analysed with the normal procedures used in rock analysis by XRF (crushing, powdering and pelletizing). The non‐destructive XRF analysis was instead conducted on splinters taken from the original geological pieces, with the shape deliberately worked to be similar to the refuse usually found at archaeological sites. Since the analysis was conducted on the raw geological fragment, intensity ratios of the suitably selected chemical elements were used, instead of their absolute concentrations, to avoid surface effects due to the irregular shape. The comparison between concentration ratios (obtained by traditional XRF methods) and the intensity ratios of the selected trace elements (obtained from the non‐destructive methodology) show that the different domains of the chemical composition, corresponding to the geological obsidians of the source areas, are perfectly equivalent. In the same way, together with the geological splinters, complete archaeological obsidians, from Neolithic sites, may be analysed and their provenance may be determined. The proposed non‐destructive method uses the XRF method. Due to its sensitivity, low cost and high speed, it is surely an extremely valid instrument for the attribution of the provenance of the archaeological obsidian from Neolithic sites.     

ON THE ADVANTAGE AND DISADVANTAGE OF BLACK HISTORY MONTH FOR LIFE: THE CREATION OF THE POST‐RACIAL ERA

This article takes the Nietzschean dictum that history must “serve life” as a point of departure for an analysis of the American institution of Black History Month. Many continue to place great faith in the power of historical education to solve problems of race in America. Against this common‐sense view, this article argues that the excessive historicization of the problem of racism is at least as oppressive as forgetting. The black history propagated during this month has mostly been a celebration that it is history and thus a thing of the past. The article makes the claim that it is precisely a surfeit of black history that has encouraged the view that racism is vanishing in the river of time. The constant demand to view American racism through a historical frame has led to the perception that racism is a problem that must be historically transcended rather than solved. In other words, it is through the widespread dissemination of black history during Black History Month and elsewhere that the historical category of the post‐racial era has been constituted. The postracial era is not, as is so often claimed, a denial of historical context. On the contrary, it is an assertion that the horrors of racist discrimination were once real but are now over and done with.     

Economic Development,Social Identity and Community Empowerment in the Central and Western Amazon

A multi-dimensional and multi-scalar perspective is used to contrast different experiences with community development involving new settlers, the historic riverine peasantry and Amerindians on and beyond the advancing frontier in the Brazilian Amazon. Local development is shown to occur only when a compromise is reached between the economic development of individual farmers, common social background and community political empowerment. However, the local development of communities does not necessarily result in regional development because contradictions present between political actors can cancel out gains in one dimension or scale vis-à-vis others and so frustrate wider processes.     

ESTIMATION OF NEAR-SOURCE GROUND MOTION AND SEISMIC BEHAVIOUR OF RC FRAMED STRUCTURES DAMAGED BY THE 1999 ATHENS EARTHQUAKE

On September 7, 1999 an earthquake with magnitude M _W =5.9 occurred close to the city of Athens in Greece. More than 80 buildings collapsed, about 150 deaths and hundreds of injuries were reported. Soon after the event a damage investigation was carried out by two of the authors in the most heavily struck areas. The most serious damages were observed in the northern suburbs of Athens, where reinforced concrete frames and masonry buildings represent the prevalent construction systems. The hysteretic energy demands imposed on RC buildings should have been rather severe considering the structural systems characteristics and the inadequate construction details. However, over-strengths, redundancy and especially the presence of infill walls, provided a significant increase of the seismic capacity and contributed to the survival of many buildings.

The objective of the present work is to reproduce and analyse the response of typical RC frames subjected to the 1999 Athens earthquake in areas where the observed damage was particularly severe but no recordings of the ground motion were available. After a general overview of the seismotectonic environment, seismological data, observed macro-seismic intensities, structural typologies and observed building behaviour, an attempt is made to identify representative excitations in the meizoseismal area. Specifically, the required accelerograms are obtained by modifying available records so as to reproduce a given global energy content and to be consistent with the observed damage. To study the seismic response of RC models, the obtained accelerograms are used to perform nonlinear dynamic analyses.
