Can the Raman spectrum of anatase in artwork and archaeology be used for dating purposes? Identification by Raman microscopy of anatase in decorative coatings on Neolithic (Yangshao) pottery from Henan,China

Scanning electron microscopy/energy dispersive X-ray analysis has earlier shown that the white background layer (slip) on painted pottery sherds (Yangshao culture, Henan, China, 4200 BC) is composed of kaolinitic clay containing titanium in the assumed form of TiO₂ at just 1 wt%. The same samples of white slip have now been studied by Raman microscopy, revealing bands characteristic of anatase, but none from the majority species, the matrix of kaolinitic clay. These results highlight the extraordinarily intense Raman scattering from even trace amounts of anatase and thus the need to recognise that, although the colours of archaeological artefacts are almost always determined by the nature of the matrix, the Raman spectrum may be determined by a highly scattering trace component such as anatase. The significance of anatase as a potential date-marker pigment on works of art and archaeological artefacts is discussed.     

The Sociopolitics of Archaeology in Quebec: Regional Developments within Global Trends

In the 1960s, archaeology was a newcomer to Quebec’s cultural francophone scene, and commercial archaeology made its first appearance at the end of the 1970s. Today, in a context of global chronic economic crisis, we intend to examine the effects of provincial and federal ideological and economic trends on the praxis of archaeology in Quebec. These include a progressive deregulation of the public sector by weakening the institutions through the termination of archaeological posts or/and non-replacement of retired archaeologists, and a progressive disengagement of the public sector through conditional regulation, accompanied by a lax attitude towards entrepreneurs, and stickler regulations for archaeologists. We present a series of current issues and examples in Quebec archaeology which illustrate these trends, in particular two case studies occurring in Montreal and Northern Quebec, respectively.     

Truth as historical recapitulation: the dead of Cape Town’s District One

In this essay, I reflect on the massive and dramatic re-emergence of the dead of Cape Town’s District One in 2003, and its aftermath. I discuss how the resurfacing of these ancestors helps us understand how heritage discourses operate in Cape Town, and how their agency forces us to consider what it means to live in the city during post-apartheid urban renewal. I argue that the agency of the District One dead hinges on their exposure of the internal workings of discourse and the associated disciplinary practices through which we experience Cape Town and its heritage. This story ends ambiguously. I discuss how, following the storage of the District One dead in the Prestwich Ossuary, the gaze on Cape Town was redirected away from the city’s past and towards its future; I explore how their reinterment foreclosed a series of discussions regarding the reconciliation of past events with the present realities of Cape Town. I argue, finally, that truth at District One can be understood as a form of historical recapitulation.     

Empires for Peace: Denis Veiras’s Borrowings from Garcilaso de la Vega

Writing The History of the Sevarambians in the 1670s, the Huguenot Denis Veiras borrowed many ideas from Garcilaso de la Vega, also known as El Inca, whose Royal Commentaries of the Incas was published in 1609. Both works describe the history of an empire and justify it on the ground that it brought peace and unity. While Garcilaso’s book purported to be a history, his selection of facts reflected his goal of improving the treatment of the Incas by the Spanish. Veiras’s story also claimed to be a history, but it was transparently a fiction, even to the point of lifting many elements from Garcilaso’s book. What both works equally emphasized was that empires could aim at, and could be justified by, the benefits they provided their subjects. Both tell stories of benevolent and paternalistic rulers who founded nearly ideal societies in the countries they conquered. These were models of empire for peace and unity rather than merely promoting toleration of differences or concord among differing parties. Veiras’s utopia thus offers an instructive case study of the effects of cross-cultural borrowings of literary and political ideas.     

The Old and the New: Qualifying City Systems in the World with Classical Models and New Data

Zipf's rank‐size rule, lognormal distribution, and Gibrat's urban growth models are considered as summarizing fundamental properties of systems of cities. In this article, they are used as statistical benchmarks for comparing the shapes of urban hierarchies and evolutionary trends of seven systems of cities in the world including BRICS, Europe, and United States. In order to provide conclusions that avoid the pitfalls of too small samples or uncontrolled urban definitions, these models are tested on some 20,000 urban units whose geographically significant delineations were harmonized in each country over 50 years between 1960 and 2010. As a result, if the models appear not always statistically valid, their usefulness is confirmed since the observed deviations from empirical data remain limited and can often be interpreted from the geohistorical context of urbanism proper to each world region. Moreover, the article provides new free software which authorizes the reproducibility of our experiments with our data bases as well as with complementary data.     

The New Cinema Going to the Dogs? The Encounter with Animal Otherness in the Film El aura

This paper explores the topic of animal alterity in Argentinian cinema in general, but primarily in Fabián Bielinsky's El aura. Through one of its much overlooked main characters, a wolfish dog, and her relationship with the human protagonist, this thriller develops a dialogue with the excluded and repressed visual subject status of animals. Historicizing this visual paradigm as originating in Renaissance perspectivism, and theorizing it alongside the gendered category of castration anxiety and the representation of women as to-be-looked-at-ness in film, this essay proposes that El aura reworks these traditions and comes to an innovative, even radical, conclusion about the possibilities of the human in relation to other, non-human forms of subjectivity. The dog fills the gap, and alters the parameters, of the missing femme fatale, if we read the film as pertaining to the noir (or neo-noir) genre. In its treatment of the relationship between the canine and human protagonists, it also reorients the viewer, thematically as much as esthetically, with regards to hegemonic binary categories such as active/passive, good/evil, predator/prey, and strong/weak. This article engages centrally with recent scholarship on human-animal relations.     

Quelques repéres historiques sur la théorie des jeux

Résumé  L'article s'attache à dégager le fil rouge qui relie les réflexions de Wilhelm Gottfried Leibniz sur les jeux de société à la théorie des jeux, telle qu'on la trouve dans l'ouvrage de John Von Neumann et Oskar Morgenstern. L'itinéraire décrit passe par les travaux de plusieurs mathématiciens du XVIII^e siècle sur différents jeux de hasard, pour aboutir aux recherches de quelques-uns des fondateurs des mathématiques modernes, comme Ernst Zermelo pour la théorie des ensembles et émile Borel pour la théorie des probabilités. II montre comment une analyse mathématique des jeux de société a débouché sur l'élaboration d'une grille générale d'analyse des phénomènes sociaux. Son cheminement révèle, en outre, la longue parenthèse du XIX^e siècle où ce programme s'est trouvé abandonné et esquisse, en conclusion, quelques hypothèses pour l'expliquer. The paper strives to find the clue which links Leibniz' thoughts on parlour games to the mathematical theory of games in John Von Neumann and Oskar Morgenstern.Magna opera the way goes through the works of several XVIII^th century mathematicians on various games of chance to reach the research of some of the modern mathematics founders, as Ernst Zermelo for the sets theory and émile Borel for the theory of probabilities. The paper shows how a mathematical analysis of parlour games ends at a general framework to study the social phenomena. Its development also reveals how this research program has disappeared, all along the XIX^th century, and suggests, in conclusion, some tentative explanations of this development.
