Metallic trace elements in wild and farmed fish from the Aveiro Region (Portugal)

International audienceThis study assessed the concentrations of 11 metallic trace elements (MTEs: As, Cd, Co, Cr, Cu, Fe, Mn, Ni, Pb, Se, Zn) in fish muscle from eight wild and farmed species collected in the Aveiro region of Portugal, an area historically affected by industrial pollution. A total of 66 samples were analyzed by ICP-MS. Mean concentrations (mg/kg ww), arranged in ascending order, were: Ni (0.0001), Cd (0.0015), Co (0.0020), Pb (0.0023), Cr (0.0179), Mn (0.0862), Cu (0.2500), Se (0.2964), Fe (1.9236), As (1.9260, total As), and Zn (3.3701). Significant differences were observed among species and between wild and farmed fish, particularly in Dicentrarchus labrax and Sparus aurata. Although Cd and Pb concentrations remained below current European maximum levels, risk assessment based on safe consumption limits (SCLnc) identified total Se, Cd, and Pb as the most restrictive elements for daily intake, especially in children. For arsenic, only total concentrations were considered, as inorganic As could not be distinguished in this study. No significant non-carcinogenic risks were identified at current national average fish consumption levels; however, the potential cumulative and synergistic effects of multiple metals in chronic exposure warrant further investigation. The Metal Pollution Index (MPI < 1 for all samples) confirmed low overall contamination. These findings underscore the importance of ongoing monitoring of trace elements in fish to ensure food safety and protect vulnerable populations

Intermediation Platforms and Geopolitical Asymmetries, Lessons from a Pandemic

International audienceTo a large extent, and particularly before vaccines became available, human societies owed their resilience during the COVID-19 pandemic to non-pharmaceutical interventions, i.e. social distancing combined with more invasive digital systems. In this paper, we consider the digital applications developed during 2020-2021, the two first years of the pandemic. We introduce a typology based on the services offered and the data flows they require, between both public and private actors. A detailed timeline of these developments shows that countries’ strategies have evolved in strong coherence with their overall digital policy. Our study demonstrates that this exogenous crisis has reinforced the critical role of intermediation platforms for maintaining society’s essential functions. Their increased centrality has contributed to intensifying information asymmetries and power imbalances, already at stake before the pandemic, both between platforms and states, as well as between countries, leading to new geopolitical equilibria

Quand Érec rencontre Erec(k). Réflexions croisées sur l’édition et l’interprétation des romans deChrétien de Troyes et de Hartmann von Aue

International audienceHartmanns von Aue Erec, die deutschsprachige Übertragung des ersten Artusromans Chrétiens de Troyes Érec et Énide, ist ein paradigmatisches Beispiel für die intensive Zirkulation von Erzählstoffen im westeuropäischen Kulturraum des Mittelalters. Aus unterschiedlichen Gründen hat für beide Romane jeweils eine Handschrift (Paris, BnF fr. 794 und Wien, ÖNB, Cod. Ser. nova 2663) eine zentrale Rolle in der editorischen und kritischen Tradition gespielt. Vorliegender Beitrag zieht eine vergleichende Bilanz der Editionsgeschichte beider Texte, der damit verbundenen Debatten sowie ihrer Folgen für die Interpretation der Texte und die Erfassung beider Autorfiguren. Aus den gekreuzten Blicken geht hervor, wie produktiv eine komparatistische Perspektive sein kann, welche die Transformationen der Texte sowohl durch ihre Überlieferung als auch durch die Editionspraxis mit einbezieht.La traduction-réécriture en langue allemande, par Hartmann von Aue à la fin du XIIe siècle, du premier roman composé par Chrétien de Troyes, Érec et Énide, est un exemple bien connu de l’intense circulation de la matière narrative dans l’espace occidental médiéval. Pour chacun des textes, un manuscrit a joué un rôle central dans les traditions éditoriale et critique (Paris, BnF fr. 794 pour le texte de Chrétien, Wien, ÖNB, Cod. Ser. nova 2663 pour celui de Hartmann). Le présent article dresse un bilan de l’histoire des éditions des deux romans, des débats auxquels elles ont donné lieu et de leurs conséquences sur l’interprétation des textes et la perception de leurs auteurs. Ce bilan croisé vise à mettre en valeur l’intérêt, pour la démarche comparatiste, de tenir compte des particularités de la tradition textuelle et de l’influence des pratiques des éditeurs modernes

Correctly rounded evaluation of a function: why, how, and at what cost?

The two accompanying files are: - The SageMath code computing upper bounds for the hardness to round of exp, trigonometric and hyperbolic functions over the firstfew binades surrounding 1;- the LACoR library that implements the BH algorithm for computing upper bounds on the hardness to roundInternational audienceThe goal of this article is to give a survey on the various computational and mathematical issues and progress related to the problem of providing efficient correctly rounded elementary functions in floating-point arithmetic. We also aim at convincing the reader that a future standard for floating-point arithmetic should require the availability of a correctly rounded version of a well-chosen core set of elementary functions. We discuss the interest and feasibility of this requirement

Women’s Europeanist networks and the gendering of EEC labour policies during the long 1960s (1957–74)

International audienceHistorians and political scientists have long traced the introduction of a reflection on the gendered impact of European public policies back to the mid-1970s. This was linked in particular to the attempt to reduce inequalities between men and women at work, and to the adoption of European legislation in this area, based on directives designed to ensure the application of Article 119 of the Treaty of Rome. This legal approach provides little explanation of the reasons, actors and modalities for putting gender issues on the agenda of the European Economic Communities (EEC). Based mostly on the archives of women’s associations linked to the European Movement, and secondarily on the holdings of several European institutions (Commission, Parliament, Council, Economic and Social Committee), this article offers an original top-down and bottom-up analysis of the process of gendering EEC policies between 1957 and 1974. It contributes to the analysis of the economisation of the EEC social policies and shows that, for women Europeanist activists of the 1960s, gender equality could not be reduced to the issue of wages. Gendering European policies neither represented a linear process of framing of social policies under the economic goals of the EEC, nor was it an insignificant tool in the affirmation of the European institutions vis-à-vis the Member States. Eventually, studying the agency of women’s associations in the inclusion of gender in EEC labour policies allows the article to shed new light on the citizen impulses in the European integration process, from the 1960s onwards
