The Gender of the Gold: an Ethnographic and Historical Account of Women's Involvement in Artisanal and Small‐scale Mining in Mount Kaindi,Papua New Guinea

The Kaindi area of Papua New Guinea is home to a large community of Anga small‐scale miners. While they constitute nearly half of the local population, women do not participate in mining to the same extent as the men. Drawing on ethnographic data this paper shows that this is not just due to personal choice but also to a series of limiting factors that include pollution beliefs, land tenure practices, the unequal control of household resources, and the gendered division of labour. Far from being simply intrinsic to Anga culture, these impediments also relate to the gendered history of the colonial goldfields and to contemporary national law and company practice in the extractive sector. Similarly, they are neither unambiguous nor resistant to change. Indeed, since the Anga first entered the mines their women have engaged in resource extraction in ever increasing numbers, both independently and alongside male relatives and partners. Through an analysis of this historical trend, my paper will show that historically conscious ethnography can help specify not only the main obstacles women face in entering artisanal and small‐scale mining (ASM), but also the conditions that lead to their strengthening or weakening through time, thus identifying factors to be stimulated or countered in policies and strategies for equitable development within the sector.     

Origins of formation waters in the Llanos foreland basin of Colombia: geochemical variation and fluid flow history

Wells located in the Colombian Andean foreland often produce biodegraded hydrocarbons and relatively fresh water (total dissolved solids concentrations of 2000 mg l^?1 dominate across most of the basin). The ratio of water to hydrocarbon in the produced fluids is high and has often been interpreted by explorationists and simulation engineers as being due to massive meteoric water invasion. To challenge this hypothesis, previously published and existing data are compiled here, along with 68 new water samples collected from both the surface (rivers) and subsurface (production wells), which are analyzed for major elements, salinity, and stable isotope compositions. The data indicate a mixed origin for the water, which involves formation water, meteoric water, and a third source that we interpret as being related to diagenetic processes (such as clay dehydration). Analyses of the variation of the parameters from north to south and west to east allow us to define the mixtures as coming from waters of different origins and make it possible to determine the relative contribution of each source.     

Reason,ridicule and religion: The age of enlightenment in England 1660–1750

Abstract

Montesquieu and Adam Smith undertook deep analyses of the structural laws of agrarian civilizations and described the traps and tendencies which would prevent any final escape from constant toil and inequality. David Hume's work in certain of his ‘Essays’ complements their work. He shows the social, political, religious and economic conditions which had made England the most free and wealthy nation in the world by his time. Simultaneously he shows the strong forces which would ultimately lead to stasis even in the English case. © 2001 Elsevier Science Ltd. All rights reserved.     

Design and Analysis of Cross Vaults Along History

The history of cross vaults began almost 2,000 years ago with a widespread use during the Middle Ages and Renaissance, becoming nowadays one of the most diffused and fascinating structural typologies of the European building cultural heritage. However, conversely to the undeniable excellence achieved by the ancient masons, the structural behavior of these elements is still at the center of the scientific debate. In this regard, with the aim of reviewing the knowledge on this subject as a concise and valuable support for researchers involved in conservation of historical buildings, with a focus on design rules and structural analysis, the present study firstly introduces the cross vaults from a historical perspective, by describing the evolution of the main geometrical shapes together with basic practical rules used to size them. Then, the article deals with the subsequent advancements in structural analysis methods of vaults, until the development of modern limit analysis.     

The christian polity of John Calvin

J.A. Hobson is known for his views on economy and imperialism. He was also concerned with social psychology and especially with the phenomenon of crowds, which was much discussed at the beginning of the twentieth century. As crowd behaviour was both collective and apparently irrational, it could undermine liberalism. However, Hobson uses crowd phenomena to bolster his own brand of social-democratic liberalism. He perceives mass behaviour as a constituent of the social dialogue favoured by liberals since J. S. Mill, and argues that alterity and festivity are themselves human traits that merit political and legal recognition. This expanded view of human nature grounds a perception of rights which includes entitlements to leisure and structureless sociability: the welfare measures which guarantee such entitlements are thus made constituents of a revised liberalism. His interpretation of the crowd also serves Hobson as a warning to social theory itself, which, he argues, should acknowledge its distance from the world it attempts to analyse. This perception of theory further acts to strengthen liberalism, as it points to the contingent, open-ended character of any view of society and hence favours dialogue and open expression of varying opinions.     

Unglazed pottery from the masjed-i jom’e of Isfahan (Iran): technology and provenance

The masjed-i jom’e of Isfahan is one of the earliest mosques of Iran. Since 1970, Italian researchers performed an extensive archaeological investigation uncovering huge amounts of finds. This study aims at investigating the technological features and provenance of the unglazed pottery finds by using a minero-petrographic approach. Twenty-three samples of storage, table and cooking wares were selected based on the recurrence of typologically identifiable fragments and fabrics. Two bricks, seven production indicators (spacers, kiln furniture, slags) and a local clay were analysed for comparison. The production indicators and most of the pottery show high-CaO concentration. Thick-walled wares contain coarse sedimentary/metamorphic inclusions. Samples with thinner walls contain similar but fine/well-sorted inclusions. The mineralogy and microstructure indicate firing temperatures mainly ranging from 850 to 1000 °C. Low-CaO samples contain coarse sedimentary inclusions; in one sample, volcanic lithics are present. Firing temperatures range from about 800 to 950 °C, and the low-CaO character can be related to their specific function for cooking foods. One sample, found in older stratigraphic levels, differs for its peculiar calcitic temper and lower firing temperature. Local production of most samples was constrained by the composition of the inclusions compatible with the sediments of the Isfahan area. High-CaO pottery shows compositional affinity with production indicators, local clay and tiles produced in Isfahan during the Safavid period. Cooking ware usually contains local temper, with the exception of a sample with volcanic inclusions, for which a non-local provenance is supposed. No appropriate information is, however, available regarding the low-CaO clays used in the area.
