Five thousand years of atmospheric Ni,Zn, As,and Cd deposition recorded in bogs from NW Iberia: prehistoric and historic anthropogenic contributions

The analysis of environmental archives from across the world has demonstrated that human perturbation of the geochemical cycles of trace metals and the resultant atmospheric metal contamination date back, at least, several millennia. However, an understanding of the local processes and timing of changes in trace metal deposition is also essential for a proper global interpretation. The Iberian Peninsula was a major mining area since prehistoric times and the analysis of environmental archives provides a good opportunity to improve our understanding of the history of mining and metallurgy in Europe. We present the results from three ¹⁴C dated peat cores from the Xistral Mountains (NW Iberia). These records are used to reconstruct past atmospheric deposition of Ni, Zn, As, and Cd. The chronology of the changes in concentrations and metal accumulation rates was found to be concordant in the three bogs, and showed great similarity to total Pb, Hg, and Pb isotope ratios as determined in previous investigations. They present a consistent view of changes in atmospheric pollution and the importance of metals in the development of human societies, especially: i) the first evidence of atmospheric metal pollution 3400 years ago, which is simultaneous with the expansion of the Atlantic Bronze Koine; ii) a pollution event between 2350 and 2150 years ago, associated to the development of so-called Celtic culture (local Late Iron Age); iii) a dramatic increase of metal fluxes in Roman times; iv) a severe and rapid increase in the last 250 years corresponding to the beginning of the industrial revolution in Europe, reflecting the emergence of the new dominant sources of pollution, and v) the increase of long range atmospheric transport of pollutants. Our data suggest that all detected ancient (until ca. 1450 cal BP) periods of enhanced Ni, Zn, As, and Cd accumulation may have had an anthropogenic origin, related to the onset and development of mining and metallurgy.     

Raw stone material supply for Upper Pleistocene settlements in Sierra de Atapuerca (Burgos,Spain): flint characterization using petrographic and geochemical techniques

Microscopy, mass spectrometry and X-ray diffraction methods were used to analyse 415 samples of natural and archaeological flint from Sierra de Atapuerca (Burgos, Spain) in order to define the different types from Neogene and Cretaceous formations in the study area, infer their genetic context and ascertain the supply sources used by hunter-gatherers who exploited this area in the Upper Pleistocene. A statistical classification model was also designed using linear discriminatory analysis and support vector machines which permitted the differentiation of the flint on an age basis.     

Liberia an(d) Empire?: Sovereignty, ‘Civilisation’ and Commerce in Nineteenth-Century West Africa

ABSTRACT

In the 1840s, Liberia was a black settler state on the West African coast which avowedly supported the connected ideologies of Christianity, commerce, and ‘civilisation’. However, from the 1870s, as the rest of West Africa began to be divided up into colonies, adherence to these ‘Western’ values did not spare Liberia’s leaders from some of the disruptive consequences of European expansionism. This article frames these consequences in the context of commercial clashes between the Liberian state and European traders (and their companies). These clashes predated Liberia’s declaration of independence in 1847, worsened thereafter, and later became increasingly politicised with the stricter enforcement of colonial law in the region in the 1870s, partly as a result of economic crisis. On the coast, Liberian officials struggled legally and militarily to stave off the activities of European smugglers with diplomatic backing. In the interior, commercial alliances were forged with local authorities in an attempt to keep out the French and the British, in particular. Conflicts over the collection of customs duties, the setting of borders, and, ultimately, the nature and extent of Liberian sovereignty, reached a climax during the Berlin Conference (1884–1885). The Conference led Liberia, by 1904, to implement its own version of colonial ‘indirect rule’: first and foremost to safeguard its independence, secondarily as a tool of expansion. In spite of major losses Liberian leaders were ultimately able to strengthen the country’s standing as a member of the international community of nations.     

Inhabiting Remote Tropical Seashores at 1500–1100 b.c.: Water,Practicalities, and Rituals in the Mariana Islands

When people first inhabited the Remote Oceanic region of the world at 1500 b.c., they generated archaeological sites attesting to their practical coastal adaptations in tandem with their ceremonial traditions, wherein water figured vitally in daily living and ritual performance. Of eight known first-settlement sites in the Mariana Islands, Ritidian in Guam uniquely incorporates one residential habitation plus two caves related to water collection, pictographs, consumption of unusual foods, and use of exceptionally decorative objects. The inter-connected findings clarify what was “special” about the special-use caves, in total articulating a fuller sense of cultural life and landscape than otherwise could be possible.     

Nudges and the limits of appropriate interference: reading backwards from J.S. Mill’s harm principle to Jeremy Bentham’s indirect legislation

ABSTRACT

The starting point of the present paper is the nudge phenomenon. The most disturbing element of nudge is its potential for individual manipulation, that is, for relying on initiatives that go beyond the acceptable limits of interference in individual choice. This feature is not ignored by nudge advocates, who discuss it extensively to justify the overriding benefits of such initiatives. In this discussion, they acknowledge the seminal importance of J.S. Mill’s harm principle, which is introduced in On Liberty. Academics without hidden agendas must look into Mill’s theories from an intellectual history perspective and study to what extent Mill’s harm principle lends support to the interference of government and society in private lives. This paper first unveils some contradictions in the interpretation of Mill’s harm principle in order to show that it is an unlikely source of philosophical justification for nudge proponents. The paper argues further that Mill was familiar with Jeremy Bentham’s writings on indirect legislation, presented in the Traités de legislation civile et pénale. It pinpoints elements of indirect legislation that are discussed by Mill in On Liberty, without ever naming them as such. The paper contends that Mill’s presentation of the harm principle can be read as a discussion with Bentham in relation to the appropriate limits of government intervention in people’s lives. This double reading of Mill and Bentham through the lens of indirect legislation makes it possible to pinpoint the main differences between the authors as regards the appropriate degree of government interference. Bentham’s theories appear to be a more appropriate source of philosophical justification for the use of nudges than Mill’s harm principle.     

‘Prevention of evil,production of good’: Jeremy Bentham’s indirect legislation and its contribution to a new theory of prevention

ABSTRACT

This paper critically analyses current depictions of prevention and tries to offer a new theoretical reflection on the concept by reconstructing it on the basis of Jeremy Bentham’s writings on indirect legislation. It is my aim not only to explore Bentham’s concept of indirect legislation as an outstanding example of enlightened social/public policy, but also to show to what extent his thoughts might be a fruitful contribution to a necessary reconceptualization of current conceptions of prevention, which are heavily criticized by many scholars.
