The Landes de Gascogne (southwest France): periglacial desert and cultural frontier during the Palaeolithic

During the last glacial period, a large part of the Aquitaine basin (southwest France) was a periglacial desert comprising coversands with low-relief dune fields surrounded by loess accumulations. OSL and radiocarbon dates show that the phase of maximum sand deposition coincides with Marine Isotope Stage (MIS) 2. Peats and gleyic palaeosoils intercalated within the sands at some sites indicate that vegetation cover was able to develop locally during short events, possibly D–O interstadials, due to raised groundwater levels in interdunal depressions. Few Palaeolithic sites have been discovered in the coversand area in contrast to the peripheral loess region. Systematic survey along a future highway corridor demonstrates that this paucity of sites is not the result of insufficient survey nor deep site burial, but rather reflects an archaeological reality. This strongly suggests that the sand area was not attractive for hunter–gatherer populations due to its reduced levels of water resources, and available vegetation and animal biomass. The distribution of cultural markers such as art items and projectile points also shows that the coversand area probably acted as a barrier separating two different cultural sub-areas, one in the Pyrenees and Cantabria, the other in the Périgord. As a consequence, the commonly accepted view that southwest France, as a whole, served as a refugia during the cold and arid phases of the Pleistocene should be replaced by a more complex one that reflects the fact that a large part of the territory was almost unoccupied and that human populations were concentrated along alluvial valleys.     

Amplitudes of orbitally induced climatic cycles and patterns of hominin speciation

Palaeoanthropologists and archaeologists have long invoked climate change to explain aspects of human evolution. Collection of new climatic and environmental data combined with new fossil discoveries and methodological improvements continue to make exploration of this link a vital endeavour in studying human evolution. The current study employs a global climatic dataset and a rigorously compiled catalogue of hominin first and last appearance dates to test the effects of changes in temperature on hominin speciation and extinction. Through the use of wavelet analysis and bandpass filters the eccentricity, obliquity, and precession components of the studied climatic record are extracted and tested independently for associations with patterns of speciation and extinction. Results suggest that all three components may play a role in speciation events, but that only the obliquity cycle shows a statistically significant relationship with extinction events. It is suggested that, whilst climatic factors could contribute to the appearance of new hominin species, subsequent competition between these species may lead to their extinction.     

Inter-actor Trust in the Planning Process: The Case of Transit-oriented Development

Inter-actor trust (or the absence of it) plays an important role in complex planning processes. Trust has received much attention in management science, but surprisingly little in planning literature despite the similarities between the two and its increasing importance in ensuring coordination between multiple, heterogeneous actors in delivering developments. This paper aims to explore the role of trust in coordination in transit-oriented developments processes, based on literature research and two empirical case studies in the region of Toronto in Canada and the province of Zuid-Holland in the Netherlands. This research suggests that in both planning contexts trust is an important element in achieving successful outcomes. Trust was often identified at a personal level as something which can bridge differences between organizations, but that can be hindered by a history of distrust between organizations. The building of trust between stakeholders seems dependent on a commitment to building a good relationship early and openness throughout. Breaches of trust, as long as they are not fatal for the relationship, can lead to a stronger trust relationship in the long term. Trust, however, is not just an individual or organizational matter: the broader institutional context was also found to have pronounced impacts on the ability of trust to take root.

The International Character of a Trimmer: Interest,Reason of State,and Balance of Power in Halifax's Political Thought

This article argues that George Savile's thought casts light on international relations in the seventeenth century. Halifax's life and works concern not only England's domestic politics, but also its foreign affairs. Indeed, he develops a clear vision of international politics. This article analyses Halifax's international thought, in particular three concepts that are closely related to one another: ‘interest’, ‘reason of state’, and ‘balance of power’. Through the study of these ideas, this article will try to point out both the novelty of Halifax's thought compared with that of his contemporaries, and to reverse the stereotypical understanding of his intellectual legacy and political behaviour. The ‘trimmer’ contrasts with Louis XIV's attempt to establish a universal monarchy across Europe, outlining a doctrine of moderation that seeks to ensure liberty, security, and restraint in international relations.     

Combining residue analysis of floors and ceramics for the study of activity areas at the Garum Shop at Pompeii

In this paper, we propose the application—for the first time in the Mediterranean area—of the combination of the study of chemical residues in floors and ceramics, with the aim of providing information about the activities carried out in archeological buildings. We chose the Garum Shop at Pompeii to test the method. In fact, due to the peculiarity of this archeological context, it provided an ideal case in which the activities performed are in part known, and the ceramic vessels recovered are still in situ. Floor samples were studied by means of spot tests developed in Mexico aimed at identifying the presence of phosphates, fatty acids, and protein residues, while the organic residues preserved in the ceramic matrix of amphorae, dolia, and other ceramic vessels were studied by gas chromatography coupled with mass spectrometry. Moreover, we integrated the data obtained with specific studies directed at better identifying the solid residues found inside two of the amphorae studied: botanical studies of fruit stones recovered in a Dressel 20 amphora and the characterization of the lime preserved in an African amphora. The research allowed for the identification of the traces of some of the activities performed, such as cooking and producing garum in the floors of the building, and the use and re-use of amphorae and dolia before the Vesuvian eruption.     

Social class and wealth inequality in Italy over 20 years, 1993–2014

Italy is facing its worst economic crisis since the Second World War. As many studies have already shown, the crisis is affecting the country’s social class structure, thus accentuating several inequality tendencies. In this connection, the empirical purposes of this article are twofold: (1) to analyze whether accumulation and inequality in wealth are growing or declining in absolute terms; and (2) to investigate the relationship between social class and wealth inequality. To this end, we adopt a longitudinal approach – that is, we take the 1993–2014 period into account – by using data from the Italian Survey of Household Income and Wealth. Our findings suggest that overall net worth has trended down in the years following the beginning of the crisis, and that inequality in wealth has basically been increasing during the 20-year period, with a decline from 2012. However, there has been no persistent social splitting process in wealth distribution by social class. Rather, there is a high (and increasing) level of domestic differentiation in terms of household wealth by class, mainly within the lower class and self-employed middle class, which could put further stress on social cohesion standards and allow new forms of social vulnerability to emerge.     

Conserving Rainforest 4: aural geographies and ephemerality

Works of installation sound art are inherently spatial. Documentation of this form, which dates from the 1950s, involves an engagement with diverse histories of geographical knowledge and oral-historical methodology. David Tudor's Rainforest 4 (1973) is a performed sculptural sound installation which remains the best-known of his pieces. Its durability—when most other of his works remain unperformed, partly because they are too hermetic to decipher or depend on unavailable technologies—belies its “score” which consists of a simple diagram and a few words. Oral history, formal and informal, is not only key to understanding the history of the piece, but is integral to its performance. This paper explores some historical geographies of Rainforest 4 and the aesthetic of ephemerality in live electronic music, for which documentation of performance is secondary. In examining the paradoxes of Rainforest 4's conservation, we explore Tudor's engagement with particular notions of nature and spirituality as well as the social hierarchies and conservative impulse which keep the piece alive.     

Inside “the system”: engineers,scientists, and the boundaries of social protest in the long 1960s

By the end of the 1960s, many engineers and scientists in the US questioned the social and political dimensions of science and technology. This introspection came as critics assailed science and technology as elements of the militaristic, alienating structure of modern society. Engineers and scientists repudiated, appropriated, or sometimes even acted in concert with these critics. Also relevant, however, in engineers' and scientists' evaluations of their role in society were the emergence of “engineering science,” pre‐existing political ideologies, and simply making a living in a volatile economy. This paper presents dissention from three vantages within the technical community: design engineer Steve Slaby at Princeton University, the Fluid Mechanics Laboratory at the Massachusetts Institute of Technology, and the activist organization Science for the People, located in chapters across the country. These cases differ in the actors' level of political consciousness, their involvement in military research, and the tactics they employed. All, however, suggest cause for reassessment both of the borders between “critics” and “scientists” and of the culture of “total control” ascribed to the era.
