An Archaeological Survey of El Camino Real de Tierra Adentro,Las Cruces—El Paso

Archaeologists from New Mexico State University surveyed El Camino Real, the earliest long-distance trail established by European colonists in North America, from Las Cruces, New Mexico, to El Paso, Texas. Our goal was to determine the location and condition of this historic trail within a strip of land that has witnessed significant agricultural, suburban, and urban development in recent years. Due to this development, many scholars have assumed that all physical traces of the Camino Real have been destroyed. Results of our research, however, suggest that not all remnants of the trail and related campsites have been lost.     

The intuitions of higher dimensional algebra for the study of structured space

Higher dimensional algebra frees mathematics from the restriction to a purely linear notation, in order to improve the modelling of geometry and so obtain more understanding and more modes of computation. It gives new tools for noncommutative, higher dimensional, local to global problems, through the notion of «algebraic inverse to subdivision». We explain the way these ideas arose for the writters, in extending first the classical notion of abstract group to abstract groupoid, in which composition is only partially defined, as in composing journeys, and which brings a spatial component to the usual group theory: An example from knot theory is used to explain how such algebra can be used to describe some structure of a space. The extension to dimension 2 uses compositions of squares in two directions, and the richness of the resulting algebra is shown by some 2-dimensional calculations. The difficulty of the jump from dimension 1 to dimension 2 is also illustrated by the comparison of the commutative square with the commutative cube-discussion of the latter requires new ideas. The importance of category theory is explained, and a range of current and potential applications of higher dimensional algebra indicated.     

Intra-site Spatial Analysis in Ethnoarchaeology

ABSTRACT

The interpretative power of quantitative intra-site spatial analysis has long been recognised by archaeologists. On the contrary, very few ethnoarchaeological works have engaged with the statistical analysis of intra-site pattern of artefacts and ecofacts. Nonetheless, ethnoarchaeology is uniquely placed to guide and assist in the identification of sound techniques and in the development of the methodology of analysis. The possibility to directly connect the distribution of the proxies under study with the activity that generated such distribution, provide the means of fine-tuning the tools we use for identifying these patterns in the archaeological record. As a consequence, archaeological methodology and interpretation both benefit from the application of improved methodologies. In this paper we review some of the most common techniques used to analyse activity areas and we provide examples of the application of such techniques to ethnoarchaeological contexts. The aim is to assess how archaeology can benefit from the intra-site spatial analysis of ethnoarchaeological contexts.     

Regional paths towards Europe 2020 targets: a spatial approach

Europe 2020 is a 10-year EU strategy, promoting smart, sustainable and inclusive growth. Despite ambitious goals, its spatially blinded approach might seriously threaten its success. Actually, large territorial disparities still affect the EU, being the basis for a strong EU-wide cohesion policy and suggesting a general re-framing of sectoral policies on a regional basis. In this respect, the paper tackles the issue of regional disparities in achieving Europe 2020 Strategy targets. As the Strategy involves different targets, principal component analysis is applied to disentangle Europe 2020 domains and to describe major differences in EU-27 NUTS 2 regional performances. In particular, two components are returned: high-employment inclusive growth and smart growth. Territorial patterns of both components are analysed, by jointly considering some geographical features that may affect them. Both a rural and a spatial effect occur: rural and remote regions show poor performances whilst the presence of spatial autocorrelation may actually lock-in negative outcomes. When considering urban rural divides, also within-regions disparities matter. Results strengthen the idea that Europe 2020, as other sectoral policies, should be translated into a regional setting according to a place-based approach: although requiring large efforts, this represents the only way to fully achieve its own targets.     

Philosophy as a cultural resource and medium of reflection for Hermann Weyl

In a talk given at Zurich in the late 1940s, Hermann Weyl discussed Ferdinand Gonseth's dialectical epistemology and considered it as being restricted too strictly to aspects of historical change. His experiences with post-Kantian dialectical philosophy, in particular Johann Gottlieb Fichte's derivation of the concept of space and matter, had been a stronger dialectical background for his own 1918 studies in purely infinitesimal geometry and the early geometrically unified field theory of matter (extending the Mie-Hilbert program). Although now Weyl distantiated himself from the speculative features of his youthful philosophizing and in particular from his earlier enthusiasm for Fichte, he again had deep doubts as to the cultural foundations of modern mathematical sciences and its role in material culture of high modernity. For Weyl, philosophical «reflection» was a cultural necessity he now turned towards Karl Jaspers' and Martin Heidegger's existentialism to find deeper grounds, similar to his turn towards Fichte's philosophy after World War I. The discussion in the late 1940s can be read as a kind of post-World-War-II «Nachtrag» to Weyl's more widely known philosophical comments on mathematics and the natural sciences published in the middle of the 1920s.     

Albert Lautman et le souci brisé du mouvement

We locate Albert Lautman's work as a sort of agent of the break of symmetry in the framework of the traditional opposition of speculative philosophy and the physico-mathematical sciences. The stakes for philosophy are, with very rare exceptions, very poorly perceived. On this level, we return to the question of Lautman's supposed «Platonism» and we confront it with its fundamental reading of Martin Heidegger. The consequences of this insertion in the heideggerian furrow are fundamental for a just restitution of this thought and this philosophy into what they retain in current thought. On the other side, that of Lautmanian entries in the field of mathematical physics, we insist on the extreme prospective alacrity of his gaze, his philosophic power which comes to reinforce this strange sensibility toward what constituted the essential part of theoretical mathematics and physics in his time. In this sense, his position occupies actually one of the nodal points of the «surrationalistic» landscape.     

Présence de Ferdinand Gonseth dans la pensée de Gaston Bachelard

The purpose of this paper is to analyse the influence of Ferdinand Gonseth's epistemological and philosophical reflection on Gaston Bachelard. This will be done on at least two levels: on the one hand, on the level of direct quotations of Gonseth's texts and notions made by Bachelard; on the other, on the level of an agreement between the two conceptions concerning some central issues— agreement that lets one suppose an influence of Gonseth on Bachelard or an identity between their views. One concludes recalling the notion of «subjectivité quelconque», suggested to Bachelard by the gonsethean idea of «logique comme physique de l'objet quelconque», and seeking to grasp the differences between Bachelard's notion of «sujet quelconque», and Gonseth's one ofhomo phenomenologicus. One could define Bachelard's and Gonseth's epistemologies as two phenomenologies of the man of science: this is their main common feature.     

Des porte-parole protestants au chevet de l'édit de Nantes moribond

This article shows how the Edict of Nantes (1598), that had been criticized by French Protestants when it came out, progressively became the symbol of their belonging to the French nation and the acceptance of their religious particularity. But it is finally after its revocation (1685) that this Edict appears to make most sense to the Huguenot spokesmen. Thinking from a theological point of view as well as an historical, juridical and philosophical one, they consider it as a symbol of religious freedom. However, it is only by giving up their former status lost with the Revocation that they manage to develop an original thinking on the relationship between the State and individuals. In order to achieve this, they must distinguish between the subject or the citizen on one hand, and the believer on the other. But this distinction implies the renunciation of the nostalgia for aProtestant body, recognized as such in the kingdom of France.     

Continental Patterns in Stone Tools: A Technological and Biplot-Based Comparison of Early Late Pleistocene Assemblages from Northern and Southern Africa

The technology of the end products i.e. blades and points in Late Pleistocene stone artefact assemblages from Klasies River, South Africa, and the Nile Valley, Egypt, are compared. The comparison includes univariate and multivariate analysis of metrical attributes enhanced by graphical biplot displays. The end products in these assemblages are either dominantly points or blades and this is related to the core reduction strategy adopted. The MSA 11 from Klasies River and the Nubian Complex industry from the Nile Valley are point industries made in the Levallois tradition, while the MSA 1 from Klasies River and the Taramsan from the Nile Valley may be non-Levallois or adapted Levallois blade industries. Dating of the assemblages shows the changes between dominant core reduction strategies are sequential and time restricted in both South and North Africa. It is concluded that variability of the same kind occurs in Middle Stone Age and Middle Palaeolithic assemblages south and north of the Sahara in the early Late Pleistocene.Dans cet article, les technologies des produits recherchés, des lames et des pointes, pour certains ensembles lithiques de Klasies River, Afrique du Sud et la Vallée du Nil, Egypte, sont comparées. Cette comparaison implique des analyses univariées et multivariées de variables métriques biplot. Les produits recherchés sont bien des pointes que des lames, selon les stratégies dexploitation adoptées. Le MSA II de Klasies River et le Complexe nubien de la Vallée du Nil sont des industries à pointes issues de la tradition Levallois. Par contre, le MSA I de Klasies River et le Taramsien de la Vallée du Nil évoquent une technologie de production non-Levallois ou Levallois modifiée. Les éléments de datation disponibles indiquent que les changements dans la prépondérance des stratégies dexploitation senchaînent dans une séquence chronologique bien identifiable, aussibien dans lAfrique du Sud que lAfrique du Nord. On arrive à la conclusion quune variabilité du même caractère est attestée dans les ensembles du Middle Stone Age et du Paléolithique moyen au sud et au nord du Sahara, pendant le Pléistocène supérieur ancien.
