Introduction Dès l'école maternelle, les compétences numériques précoces varient considérablement d'un enfant à l'autre. Afin de réduire ces inégalités dès le plus jeune âge (Ramani & Siegler, 2008), les apprentissages numériques font l'objet de réflexion approfondie dès la maternelle dans différents pays (Starkley, Klein & Wakely, 2004; Vilani, 2018). En effet, de nombreuses recherches ont démontré l'existence d'une relation forte entre les compétences numériques chez le jeune enfant d'âge pré-scolaire et les compétences mathématiques à l'école primaire et secondaire (Stevenson & Newman, 1986; Jordan, Kaplan, Ramineni & Locuniak, 2009; Geary, Hoard, Nugent & Bailey, 2013; Watts, Duncan, Siegler & Davis-Kean, 2014). De plus, il a été montré que les interventions précoces ciblant les forces et faiblesses individuelles permet de réduire des troubles d'apprentissage (Vellution & Scanlon, 2002). Methode Dans cette étude, 84 enfants d’âge préscolaire se situant entre 48 mois et 60 mois ont été répartis en 3 groupes pour participer à différents types d'intervention pédagogique : 27 enfants ont suivi un programme d'intervention numérique basé sur les jeux de doigts stimulant le développement de la compréhension de la cardinalité, 28 enfants ont suivi un programme de lecture partagée ciblant les précurseurs au langage écrit, et enfin 29 enfants ont suivi un programme ciblant la motricité globale. Les interventions pédagogiques ont été données en parallèle pendant dix semaines, trente minutes par jour, cinq fois par semaine. Resultats Les résultats montrent que les enfants qui ont participé au programme numérique ont davantage progressé dans la compréhension de la cardinalité que les enfants qui participaient aux autres interventions. Ils ont également montré une amélioration des compétences arithmétiques précoces (non entrainées dans le programme) que les autres groupes. Discussion Ces résultats montrent l'efficacité d'intervention précoce réalisée directement en milieu scolaire sur le développement des précurseurs aux compétences mathématiques.

Ostia è conosciuta per le insule di età medio-imperiale e le case di età tardo-antica. Le case ad atrio invece sono poco note perché grande parte di esse fu sepolta sotto la città del II secolo d.C. Le prime case di questo tipo furono però scavate già nel 1919. Nuove furono scoperte durante gli scavi per l’EUR, ma la maggior parte di queste abitazioni che conosciamo furono scavate nel corso della campagna condotta dal Gismondi allo scopo di indagare le fasi di età repubblicana e primo-imperiale della città (1947-52). Di recente, gli scavi eseguiti sotto la Schola del Traiano hanno fornito nuovi dati stratigrafici e nuove datazioni basate sullo studio dei materiali. La conoscenza della Domus a Peristilio è stata accresciuta ed è stata portata alla luce una nuova casa con il suo sistema decorativo, la Domus dei Bucrani. In sintesi, conosciamo una quindicina di case ad atrio, ma nessuno ha proposto uno studio complessivo su questo tipo abitativo. I nuovi dati di scavo e una indagine nell’archivio ostiense hanno gettato una nuova luce sulle case ad atrio a Ostia e sulla loro integrazione nel contesto urbano. La scoperta della Domus dei Bucrani e il riesame della Domus a Peristilio hanno sconvolto alcune certezze riguardo a Ostia repubblicana e augustea e hanno aperto nuove strade alla ricerca. In previsione della loro pubblicazione, vorremmo proporre una sintesi su aspetti poco conosciuti, basandoci sui risultati delle recenti ricerche. Affronteremo l’organizzazione spaziale di questa forma dell’abitare e la sua evoluzione nel tempo. In primo luogo, cercheremo di definire quali edifici sono case ad atrio. Infatti, tutti gli edifici ritenuti case ad atrio non lo sono, come risulta dall’esame della documentazione di scavo conservata presso gli archivi del PAOst. Poi, ci interesseremo alla continuità della pianta di questa forma repubblicana dell’abitare fino all’inizio del II secolo d.C. Mostreremo che parecchie case furono in parte distrutte e ricostruite secondo la stessa pianta nella prima età imperiale. Infine, rifletteremo sui cambiamenti dell’organizzazione interna delle case ad atrio dopo il Bauboom del II secolo. [less ▲]

Este trabalho tem por objetivo elaborar o estado da arte sobre a questão da fotografia, relacionando a teoria semiótica atual com o campo muito vasto e diversificado dessa mídia, estudada por várias disciplinas, tais como a sociologia das mídias, a filosofia da imagem, as ciências da informação e da comunicação. A obra se consagra a uma exploração semiótica das teorias da fotografia até aqui elaboradas por meio de outros paradigmas disciplinares, submetendo à revisão os trabalhos de Roland Barthes, Walter Benjamin, Philippe Dubois, Jean-Marie Floch, JacquesFontanille, Nelson Goodman, Algirdas Julien Greimas, Rosalind Krauss e Jean-Marie Schaeffer. Este estudo crítico e comparativo forma um terreno propício para uma reflexão renovada sobre questões fundamentais, tais como a indicialidade, a transparência/opacidade das imagens fotográficas e seus estatutos sociais. O campo da fotografia será explorado especialmente segundo três níveis de pertinência semiótica: textualidade, medialidade e objeto material. É possível assim abordar problemas cruciais da significação: a definição do objeto de estudo, as estratégias de análise, as práticas e os gêneros implicados por essa mídia que atravessa domínios tão diversos quanto a arte, a ciência e a documentação histórica. Desse modo, nos concentraremos em aprofundar certas questões que sempre foram controversas na literatura sobre a fotografia (studium/punctum, aura, etc.) e em levantar certo número de problemas de semiótica contemporânea, tais como a relação entre imagem fotográfica e corporeidade, as práticas de instanciação e de recepção, os gêneros da fotografia, a conservação do patrimônio, a digitalização e as práticas de catalogação museográfica.

Intrinsically disordered proteins and regions (IDPs/IDRs) make up a large part of viral proteomes, but their real prevalence across the global plant virome are still poorly understood, partly because of their massive diversity. Here we propose an evolutionary quantitative proteomic approach to foray into genomic signatures that are preserved in the amino acid sequences of orthologous IDRs. Markedly, we found that relatively abundant IDP varies substantially between viral species and within plant virus families, including according to genome size, partition or replication strategies. We also demonstrate that most encoded proteomic modules of the plant virome contain multiple disordered features that are phylogenomically preserved, and can be correlated to genomic, bio-physical and evolutionary strategies. Furthermore, our focused interactome-wide analysis highlights lines of evidence indicating that various IDPs with similar evolutionary signatures modulate viral multifunctionality. Moreover, estimated fractions of IDR in the vicinity of pivotal evolutionary structural signatures embedded in interaction modules are strongly enriched with affinity binding functional annotations and relate to vector-borne virus transmission modes. Importantly, Molecular Recognition Features (MoRFs) are abundantly widespread in IDRs of viral modules and their binding partners. Finally, we propose a coarse-grained conceptual framework in which evolutionary proteome-wide IDP/IDRs patterns can be, rather, reliably exploited to elucidate their foundational fine-tuning role in plant virus transmission mechanisms. While opening unexplored avenues for consistently predicting virus-host functions for many new or uncharacterized plant viruses based on their proteomic repertoire, other considerations advocating further structural IDP research in Plant Virology are thoroughly discussed in light of viral evolution.

The distribution of natural radionuclides in sediments from Douala, Cameroon has been carried out based on X- and γ-ray spectrometry. Radiological health parameters were evaluated and found to be lower than the internationally approved values for actions. Soil elemental characterization and differentiation displayed the concentration of major elements. In addition, the principal component analysis (PCA) established correlations between different parameters of the study by calculating linear Pearson, Kendall's tau, Spearman's rho correlation coefficients, and cumulative probabilities. The total average concentrations of radionuclides 235U, 232Th, 226Ra, and 40K were 3.2, 53.1, 33.4, and 301.2 Bq/kg, respectively. The principal component analysis based on linear Pearson, Kendall's tau, Spearman's rho correlation coefficients, and cumulative probabilities calculations displays a strong correlation coefficient only between Ra-226 and U-235. The combination of spectrometry, PCA results, and comparison with previous studies highlighted the main characteristics of the investigated area to be illustrative dregs from the Continental margin. As a pioneering study using both spectrometric and PCA methods in Douala, the method was proved to be useful, and the results would be set as a database for future investigations. [less ▲]

Transcranial Magnetic Stimulation (TMS) is a form of non-invasive brain stimulation, used to alter cortical excitability both in research and clinical applications. The intermittent and continuous Theta Burst Stimulation (iTBS and cTBS) protocols have been shown to induce opposite after-effects on human cortex excitability. Animal studies have implicated synaptic plasticity mechanisms long-term potentiation (LTP, for iTBS) and depression (LTD, for cTBS). However, the neural basis of TMS effects has not yet been studied in human neuronal cells, in particular at the level of gene expression and synaptogenesis. To investigate responses to TBS in living human neurons, we differentiated human SH-SY5Y cells toward a mature neural phenotype, and stimulated them with iTBS, cTBS, or sham (placebo) TBS. Changes in (a) mRNA expression of a set of target genes (previously associated with synaptic plasticity), and (b) morphological parameters of neurite outgrowth following TBS were quantified. We found no general effects of stimulation condition or time on gene expression, though we did observe a significantly enhanced expression of plasticity genes NTRK2 and MAPK9 24 h after iTBS as compared to sham TBS. This specific effect provides unique support for the widely assumed plasticity mechanisms underlying iTBS effects on human cortex excitability. In addition to this protocol-specific increase in plasticity gene expression 24 h after iTBS stimulation, we establish the feasibility of stimulating living human neuron with TBS, and the importance of moving to more complex human in vitro models to understand the underlying plasticity mechanisms of TBS stimulation.

Après une période d’oubli relatif, Juvénal redevient à la mode à partir du IVe s. Ce sont surtout les auteurs chrétiens qui le citent pour illustrer et critiquer les travers moraux de la société romaine. Le succès de Juvénal fut très important entre la fin du IVe et le VIe siècle. Il est lu en Italie, Gaule, Espagne et Afrique. Son succès n’est pas moindre en Orient. Juvénal est très présent chez Jean le Lydien, préfet du prétoire d’Orient sous Justinien, qui le cite dans son traité De magistratibus. Jean Malalas, qui étudia le droit à Antioche, parle de l’exil de Juvénal, qui aurait été puni pour avoir attaqué le danseur Paris, amant de Domitien. On trouve aussi des traces de connaissance du Juvénal dans le traité περὶ πολιτικῆς ἐπιστήμης connu par un palimpseste du Vatican (Vat. Gr. 1298) et attribué à Menas Patricius, magister officiorum de Justinien. Cet auteur attribue faussement à Juvénal un vers de Perse, ce qui montre que les deux poètes circulaient conjointement en Orient comme en Occident. On observe une présence très forte de Juvénal dans l’Ars de Priscien, professeur de latin à Constantinople. Les vers de Juvénal lui servent à illustrer des règles grammaticales au même titre que des passages d’auteurs plus classiques comme Virgile, Salluste, Cicéron et Térence. L’influence de Juvénal se fait aussi sentir sur des auteurs d’origine grecque écrivant en latin. Claudien d’Alexandrie trouve en Juvénal un modèle pour les invectives qu’il écrit contre Eutrope. L’africain Corippe, qui vint à Constantinople à la fin du règne de Justinien, se souvient régulièrement de Juvénal dans son épopée intitulée Ioannis (De bellis Libycis) célèbre la conquête byzantine de l’Afrique vandale. La preuve la plus tangible de la présence de Juvénal en Orient et de son étude dans les milieux hellénophones vient du fragment d’Antinoë, publié par C.H. Roberts (1935). L’écriture utilisée est l’onciale juridique de type B-R, une écriture répandue dans les chancelleries pour la rédaction les manuscrits juridiques, spécialement durant le règne de Justinien. Le fragment d’Antinoë est un témoin direct de l’activité de copie et de commentaire de textes d’auteurs latins à Constantinople. Il présente des accents et des marques de quantité ajoutés par une seconde main ainsi que des annotations marginales et interlinéaires en grec et en latin dues à d’autres mains (Roberts distingue 5 mains différentes). Le fragment de Juvénal provenant d’Antinoopolis est représentatif d’un lectorat hellénophone intéressé par la littérature latine durant la période byzantine à un niveau avancé. [less ▲]
