Producción artesanal doméstica en la cultura preclásica de Chupícuaro, Guanajuato: el ejemplo de la alfaría. In Economías domésticas: perspectivas desde el pasado, en el presente y hacia el futuro
No full textInternational audienceEste capítulo se centra en el utillaje para demostrar que es un marcador esencial para identificar las áreas de producción cerámica cuando se carece de otras evidencias materiales más claras. Las excavaciones realizadas en el sitio TR.6 “El Cuizillo de Don Fidel Salinas” no localizaron áreas de fabricación y cocción, pero evidenciaron numerosos utensilios de barro cocido y de piedra probablemente utilizados para esta actividad artesanal. El estudio tecno-morfológico de estos artefactos, completado por el análisis traceológico de una muestra, indica que se trataba de herramientas especializadas utilizadas en diversas etapas de la fabricación cerámica. Nuestro estudio muestra que la morfología de estos artefactos se adaptó a las formas compuestas que caracterizan a la cerámica Chupícuaro, que se hizo cada vez más compleja y diversificada a lo largo del tiempo. Sus características, así como los datos contextuales, demuestran que la elaboración de la cerámica, tanto de vasijas finas ˗ pintadas y monocromas -, como comunes, se llevaba a cabo en un ámbito doméstico. Además, los datos actualmente disponibles sugieren que no todos los asentamientos Chupícuaro fabricaban cerámica y que existían especialidades artesanales a nivel de pueblo

Central values of additive twists of Maa{\ss} forms -functions
No full text50 pagesInternational audienceIn the present paper we study the central values of additive twists of Maa{\ss} forms -series. In the case of the modular group, we show that the additive twists (when averaged over denominators) are asymptotically normally distributed. This supplements the recent work of Petridis--Risager which settled an averaged version of a conjecture of Mazur--Rubin concerning modular symbols. The methods of the present paper combine dynamical input due to Bettin and the first named author with the new fact that the additive twists define quantum modular forms in the sense of Zagier. This latter property is shown for a general discrete, co-finite group with cusps. Our results also has a number of arithmetic applications; in the case of Hecke congruence groups the quantum modularity implies certain reciprocity relations for twisted moments of twisted -automorphic -functions, extending results of Conrey and the second named author. In the case of cuspidal Maa{\ss} forms for the modular group, we also obtain a calculation of certain wide moments of twists of the -function of the Maa{\ss} form
Les animateurs parlent mal aux enfants
No full textInternational audience« Ils parlent mal aux élèves ! ». Voilà une parole souvent entendue dans les salles des maîtres des école primaires lorsqu’une enseignante, fatiguée de sa matinée de classe, vient s’installer auprès de ses collègues après avoir traversé le réfectoire ou la cour et qu’elle déplore machinalement l’atmosphère qui y règne. Comment comprendre ce jugement et quels enjeux dissimulés pourraient expliquer son caractère trop commun
Critical Minerals in an Age of Geopolitical Rivalry: Stockpiling, Refining Constraints, and the Limits of Friend-Shoring
No full textGeopolitical tensions between the United States and China pose significant risks to global critical-mineral supply chains, particularly because refining capacity for most critical minerals, including aluminium, copper, nickel, tin and zinc, is overwhelmingly concentrated in China. Using monthly data from 1995–2025 and a structural VAR-local projection framework, we estimate the dynamic effects of exogenous shocks to the US-China Political Relations Index (PRI) on mineral markets. We find that geopolitical deterioration systematically induces significant precautionary stockpiling. We then construct a multidimensional friend-shoring index incorporating reserves, alignment, regime type and distance, showing that only a narrow set of United States partners, primarily Australia and Canada, offer feasible pathways for refining diversification. The policy recommendation stemming from our findings is that the United States should make strategic stockpiling of refined critical minerals, rather than raw ores, the centerpiece of its strategy to build supply chain resilience, while negotiating long-term bilateral packages for the supply of refined critical minerals with Australia and Canada

No full textInternational audienceQuand nous avons imaginé cet ouvrage collectif poursuivant les différents points d’interrogations soulevés pendant le colloque TEXTE & IMAGE 6 — Pour un nouveau contrat social de l’errance : entre Art[S], Territoire[S], Blockchain[S] et Crypto- monnaie[S] — qui s’était déroulé à La Valette2 en 2021, nous pensions encore avoir le temps. Le temps de développer avec Claude Rutault une extension de sa Définition / Méthode 169 AMZ par rapport à la blockchain ; le temps de vous offrir avec cette extension que nous avions intitulée [AMZ] U-P — avec un petit smiley nous tirant la langue — comme un pied de nez offert à la postérité autour de l’œuvre de cet artiste majeur de la fin du XXe siècle..
Of Gods and Men? Animals acting as humans in the Proto-Elamite Classic Style
No full textInternational audienceArchaeological research in the Ancient Near East is often saturated with religious interpretations. Across fields such as urban planning, architecture, material culture, and iconographic studies, concepts of ritual, cult, mythology, cosmology, and cosmogony dominate and shape our understanding of past societies. While the value of such perspectives is undeniable, it is worth questioning the tendency to “sacralize” archaeological discoveries. Iconographic studies within the glyptic domain, in particular, frequently interpret symbols or figures almost exclusively through a religious lens. However, alternative interpretations—rooted in social, political, or economic practices—are equally compelling and deserve greater attention. The proto-Elamite glyptic style, dating to the late IVth millennium BCE, is a striking example of this phenomenon. Found on cylinder seals from Iran, its distribution spans a vast region, from Khuzestan to Sistan. This period, known as proto-Elamite period, represents a pivotal moment in Iranian history, marked by the advent of writing and the emergence of complex proto-urbanization processes. These seals, used in local and household administrative contexts, display a highly original and distinctive figurative repertoire, featuring scenes of animals acting as humans, long regarded as fantastical or mythological. This article challenges this perspective, proposing instead the possibility of a deliberate staging of proto-Elamite society. Through this animal-themed iconographic repertoire, socio-economic and, above all, political actors depicted themselves to legitimize and uphold the established order
