Student Partners in Task Design in a computer medium to promote Foundation students' learning of mathematics
2018
International audience; A team consisting of three mathematics education teacher-researchers, four former Foundation students (called Student Partners, SPs), and two analytic assistants worked together to produce mathematical tasks in a computer medium for the mathematical learning of current Foundation students (FSs). We have explored the collaboration between the SPs and researchers, the processes and outcomes of task design, and the contribution of the collaboration to tutorial teaching of FSs. We seek insight into the learning of all concerned of mathematics, mathematics teaching, task design and personal-professional development. The project is ongoing. Here we introduce the project an…
Epistemic and didactic values of the demonstrative process in different cultures: a case study in Geometry with Chinese and Italian students

"La cruna dell'ago": il migrante fra mobilità e controllo
2015
Il testo costituisce l'introduzione dei curatori al volume "Il traffico di migranti. Diritti, tutele, criminalizzazione". Essa fornisce una breve descrizione dei problemi connessi al tema e dei contributi raccolti.
Les traductions latines de textes hagiographiques byzantins de la période médio-byzantine
2019
The present article attempts to record and present as much as possible the Latin translations of hagiographical texts during the Middle Byzantine period. The texts are first approached from a literary point of view, then a historical presentation is attempted, referring to their possible functional use in the traditions of the two churches, Constantinople and Rome.
Carnaval y música: una breve semblanza de la Tuna Compostelana de 1888
2021
At the end of the 19th century, Spanish carnivals have been marked by the participation of the different tunas or also known as, estudiantinas. These groups achieved significant relevance in Galicia, especially in the city of Compostela, which, year after year, encouraged and supported the formation of groups of this nature to liven up the carnivals in the different Spanish cities. Although, different from its predecessors, the Santiago Tuna of 1888 ventured and made its mark in history, thanks to its intrepidity in having been the first Galician group that crossed the borders and enlivened the carnivals in the cities of the neighboring country, Portugal. This research, approached from a hi…
Debating Sound Money in Early Modern Europe: From Dualist to Metallic Monetary Systems
2019
International audience; In this paper, we present the monetary debates in Europe from the XVIth to the XVIIIth centuries from the viewpoint of the problem of good and sound money. The framework of the paper is built on a typology of monetary systems, by which a dualist system is distinguished from a metallic one. Under the dualist system, the value in units of account of the specie in circulation was defined by monetary proclamations (Einaudi locates this era from Charlemagne to the French Revolution). Metallist proponents aimed at preventing any kind of manipulations with a radical transformation of the system of payment, which gave birth to a metallic monetary system from the very end of …
Arbuscular mycorhizal proteomes: what news at the nearby and distant horizon?
2007
International audience; Proteomics has soon emerged as a powerful tool to point out protein modifications in roots interacting with arbuscular mycorrhiza (AM) fungi. Depending on the developmental mycorrhizal stage and on the available amount of mycorrhizal material, untargeted and/or sub-cellular proteomic approaches were applied to reveal and identify proteins whose accumulation was modified during the AM colonisation of Medicago truncatula roots. For the early stage of symbiosis, the protein patterns obtained from noninoculated roots and roots synchronized for appressorium formation in wild-type (Jemalong J5), penetration-defective (TRV25, dmi3) and autoregulation-defective (TR122, sunn)…
Modelling Keloids Dynamics: A Brief Review and New Mathematical Perspectives
2022
The keloids are fibroproliferative disorders described by an excessive growth of fibrotic tissue, which also invades adjacent areas (beyond the original wound borders). Since these disorders are specific to humans (no other animal species naturally develop keloid-like tissue), the experimental in vivo/in vitro research has not lead to significant advances in this field. One possible approach could be to combine in vitro human models with calibrated in silico mathematical approaches (i.e., models and simulations) to generate new testable biological hypotheses related to biological mechanisms and improved treatments. Since these combined approaches do not really exist for keloid disorders, in…
Transcriptomic and proteomic responses of Microbacterium sp. C448 exposed to sulfamethazine antibiotic
2022
International audience; The Microbacterium sp. C448 was isolated from a soil regularly exposed to sulfamethazine(SMZ), for its ability to partly mineralise this antibiotic and other related sulfonamides.The aim of our study was to explore its metabolic adaptation towards exposure to SMZenvironmental (10 mg/L) and medicinal (250 mg/L) concentrations. Its transcriptomic andproteomic responses were analysed by focusing on the degradation regulon (sad genes) andresistance genes (folP and sul1).The transcriptomic and proteomic results were essentially congruent whatever theconcentrations tested. In culture conditions, exposure to the highest concentration of SMZ led tothe highest sad expression …
Capturing learning in classroom interaction in mathematics: Methodological considerations
2015
International audience; This paper discusses issues of how to transcribe and analyze video-recordings when studying learning in small group work in mathematics. Since bodily features of interaction and the use of artefacts play important roles in mathematical reasoning, a multimodal approach to transcribing is necessary. Thus, the theoretical grounding for transcriptions has to be in accord with the perspective on learning adopted in the analysis. In the paper, the principles for studying what Radford (2000) refers to as knowledge objectification processes when learning mathematics will be discussed.
