Classicisme et résonances contemporaines : une lecture des Discours leuctriens (or. xi-xv) d'Aelius Aristide

Les Discours leuctriens sont un groupe déclamatoire d'Aelius Aristide mettant en scène la question des alliances athéniennes dans l'après-Leuctres. Ce sujet a été considéré comme éloigné des préoccupations politiques des Grecs du IIe siècle de notre ère. Le mémoire prend le relais des avancées historiques et rhétoriques pour redéfinir la résonance que pouvait avoir cette oeuvre à la période romaine. L'approche est principalement littéraire mais donne une grande importance à la situation politique des cités grecques de la province d'Asie. Nos conclusions sont que la vision de l'histoire véhiculée par ces discours est conforme à celle que développe Aristide dans la défense de la concorde; que les passages comportant des parallèles verbaux et thématiques avec la description de Rome ne portent aucun jugement direct sur celle-ci, mais des réflexions pertinentes dans l'appréhension de son pouvoir; finalement, que ces résonances contemporaines ne sont pas contradictoires avec la fonction littéraire des déclamations

Integration of oral health into primary care : a scoping review protocol

Integrated care has been introduced as a means of improving health outcomes and access to care, and reducing the cost of healthcare. Despite its importance, the integration of oral health into primary care is still an emerging healthcare pathway. This scoping review protocol has been developed and funded by the Canadian Institutes of Health Research to provide an evidence-based synthesis on a primary oral healthcare approach and its effectiveness in improving oral health outcomes

ENVIRONMENTAL LABELING OF ELECTRICAL ELECTRONIC EQUIPMENT (EEE) IN FRANCE: INFORMATION FOR CONSUMERS

The current regulatory framework for Electrical and Electronic Equipment (EEE) is changing and now requires manufacturers to disclose the environmental performance of their products. This means that manufacturers must perform a life cycle analysis (LCA) on their entire range of products. An LCA is a recognized and standardized methodology for assessing the environmental impact of activities. However, communicating this information to consumers is challenging because it can be complicated.Despite this challenge, there is currently no common standard for communicating environmental information to consumers. The objective of this study is to explore the best practices for conveying environmental information. To achive this, a review of current environmental labeling approaches and recommendations available in the literature is conducted. Additionally, consumer requirements are collected and analyzed through a questionnaire that employs both quantitative and qualitative methods. The information collected is then used to develop the best practices for implementing environmental labeling for EEE

Academically buoyant students are less anxious about and perform better in high-stakes examinations.

BACKGROUND: Prior research has shown that test anxiety is negatively related to academic buoyancy, but it is not known whether test anxiety is an antecedent or outcome of academic buoyancy. Furthermore, it is not known whether academic buoyancy is related to performance on high-stakes examinations. AIMS: To test a model specifying reciprocal relations between test anxiety and academic buoyancy and to establish whether academic buoyancy is related to examination performance. SAMPLE: A total of 705 students in their final year of secondary education (Year 11). METHODS: Self-report data for test anxiety and academic buoyancy were measured in two waves in Year 11. Examination performance was taken from the mean English, mathematics, and science scores from the high-stakes General Certificate of Secondary Education (GCSE) examinations taken at the end of Year 11. RESULTS: Measurement invariance was demonstrated for test anxiety and academic buoyancy across both waves of measurement. The worry component of test anxiety, but not the tension component, showed reciprocal relations with academic buoyancy. Worry predicted lower mean GCSE score and academic buoyancy predicted a higher mean GCSE score. Tension did not predict mean GCSE score. CONCLUSION: Academic buoyancy protects against the appraisal of examinations as threatening by influencing self-regulative processes and enables better examination performance. Worry, but not tension, shows a negative feedback loop to academic buoyancy

A partial form of inherited human USP18 deficiency underlies infection and inflammation

International audienceHuman USP18 is an interferon (IFN)-stimulated gene product and a negative regulator of type I IFN (IFN-I) signaling. It also removes covalently linked ISG15 from proteins, in a process called deISGylation. In turn, ISG15 prevents USP18 from being degraded by the proteasome. Autosomal recessive complete USP18 deficiency is life-threatening in infancy owing to uncontrolled IFN-I–mediated autoinflammation. We report three Moroccan siblings with autoinflammation and mycobacterial disease who are homozygous for a new USP18 variant. We demonstrate that the mutant USP18 (p.I60N) is normally stabilized by ISG15 and efficient for deISGylation but interacts poorly with the receptor-anchoring STAT2 and is impaired in negative regulation of IFN-I signaling. We also show that IFN-γ–dependent induction of IL-12 and IL-23 is reduced owing to IFN-I–mediated impairment of myeloid cells to produce both cytokines. Thus, insufficient negative regulation of IFN-I signaling by USP18-I60N underlies a specific type I interferonopathy, which impairs IL-12 and IL-23 production by myeloid cells, thereby explaining predisposition to mycobacterial disease

Population variation in brain size of nine-spined sticklebacks (Pungitius pungitius) - local adaptation or environmentally induced variation?

Abstract Background Most evolutionary studies on the size of brains and different parts of the brain have relied on interspecific comparisons, and have uncovered correlations between brain architecture and various ecological, behavioural and life-history traits. Yet, similar intraspecific studies are rare, despite the fact that they could better determine how selection and phenotypic plasticity influence brain architecture. We investigated the variation in brain size and structure in wild-caught nine-spined sticklebacks (Pungitius pungitius) from eight populations, representing marine, lake, and pond habitats, and compared them to data from a previous common garden study from a smaller number of populations. Results Brain size scaled hypo-allometrically with body size, irrespective of population origin, with a common slope of 0.5. Both absolute and relative brain size, as well as relative telencephalon, optic tectum and cerebellum size, differed significantly among the populations. Further, absolute and relative brain sizes were larger in pond than in marine populations, while the telencephalon tended to be larger in marine than in pond populations. These findings are partly incongruent with previous common garden results. A direct comparison between wild and common garden fish from the same populations revealed a habitat-specific effect: pond fish had relatively smaller brains in a controlled environment than in the wild, while marine fish were similar. All brain parts were smaller in the laboratory than in the wild, irrespective of population origin. Conclusion Our results indicate that variation among populations is large, both in terms of brain size and in the size of separate brain parts in wild nine-spined sticklebacks. However, the incongruence between the wild and common garden patterns suggests that much of the population variation found in the wild may be attributable to environmentally induced phenotypic plasticity. Given that the brain is among the most plastic organs in general, the results emphasize the view that common garden data are required to draw firm evolutionary conclusions from patterns of brain size variability in the wild.</p

Body image, visual working memory and visual mental imagery

Body dissatisfaction (BD) is a highly prevalent feature amongst females in society, with the majority of individuals regarding themselves to be overweight compared to their personal ideal, and very few self-describing as underweight. To date, explanations of this dramatic pattern have centred on extrinsic social and media factors, or intrinsic factors connected to individuals' knowledge and belief structures regarding eating and body shape, with little research examining links between BD and basic cognitive mechanisms. This paper reports a correlational study in which visual and executive cognitive processes that could potentially impact on BD were assessed. Visual memory span and self-rated visual imagery were found to be predictive of BD, alongside a measure of inhibition derived from the Stroop task. In contrast, spatial memory and global precedence were not related to BD. Results are interpreted with reference to the influential multi-component model of working memory

Long life evolves in large brained bird lineages

The brain is an energetically costly organ that consumes a disproportionate amount of resources. Species with larger brains relative to their body size have slower life histories, with reduced output per reproductive event and delayed development times that can be offset by increasing behavioral flexibility. The “cognitive buffer” hypothesis maintains that large brain size decreases extrinsic mortality due to greater behavioral flexibility, leading to a longer lifespan. Alternatively, slow life histories, and long lifespan can be a pre-adaptation for the evolution of larger brains. Here, we use phylogenetic path analysis to contrast different evolutionary scenarios and disentangle direct and indirect relationships between brain size, body size, life history, and longevity across 339 altricial and precocial bird species. Our results support both a direct causal link between brain size and lifespan, and an indirect effect via other life history traits. These results indicate that large brain size engenders longer life, as proposed by the “cognitive buffer” hypothesis
