Since its creation in 1830, Belgium has experienced tensions between language and politics. The question of the linguistic or community-related nature of these tensions should be raised since they have regularly been referred to as linguistic by some researchers and as community-related by others. But the choice of these adjectives is not unimportant considering they frame the representations of the political issues at hand. The aim of this article is to tackle this question from the combined perspective of linguistics and political science. In the first, the article explores the genealogy of the adjectives ‘linguistic’ and ‘community-related’ as well as the multiplicity of their uses in the scientific literature. In the second part, it focuses on the ways citizens see and talk about Belgian federalism through the respective analyses of their mental representations and their conceptual metaphors. Such interdisciplinary endeavour, bringing together theoretical and empirical insights, seeks to yield a renewed understanding of the political relations in Belgium and to contribute to the debate about plurilingual societies.

La fertilité d’un sol conditionne la productivité des plantes, c’est pourquoi il est intéressant de connaitre la distribution des caractéristiques chimiques et morphologiques du sol afin de permettre une exploitation et une gestion optimales de celui-ci. Un versant forestier, en pente forte (140m de long, 40m de dénivelée), sur matériaux schisto-gréseux et sous une plantation de résineux fait l’objet d’un suivi du fonctionnement hydrodynamique et pédochimique en relation avec le développement des arbres. Au vu du contexte de forte pente, nous suspectons la présence d’apports par solifluction. La position dans le versant est souvent un facteur de différenciation des sols et, en préalable à l’étude de l’évolution temporelle des propriétés des sols et de la végétation et de l’évolution spatiale des flux d’eau, nous nous sommes attachés à la caractérisation de la distribution des propriétés morphologiques et chimiques le long du versant. Huit fosses ont été creusées et échantillonnées selon les horizons. Outre les descriptions selon un protocole standardisé, nous avons effectué des comptages racinaires, des mesures de densité apparente et de charge caillouteuse. Les analyses en laboratoire visent la caractérisation du statut nutritif : pH, teneurs échangeables (NH4Cl) en K, Mg, Na et Ca, et P assimilable (Dyer). Les résultats confirment l’importance de la différenciation verticale au sein des profils. On notera également une légère tendance à la hausse du pH et des teneurs en éléments nutritifs entre le haut et le bas du versant, à l’exception du dernier profil de la séquence. [less ▲]

Cette communication vise à étudier la participation des femmes migrantes marocaines à la vie sociale du « pays d’accueil » ; participation qui se réalise grâce aux activités de la vie quotidienne. En particulier, la performance publique des pratiques culinaires, observée dans une ville de la province de Milan, permet aux femmes considérées d’exercer une agency à l’intérieur des espaces institutionnellement concédés à l’expression des migrants. D’un côté, la consommation des « recettes de l’Autre » de la part de la population majoritaire détermine une incorporation de la diversité afin de la contrôler. De l’autre côté, la préparation de ces recettes consent aux migrantes d’exprimer leur subjectivité (individuelle et collective) de façon active et en présentant des aspects qui vont au-delà de la culture alimentaire. Une participation sociale fondée sur le partage de nourriture donne la possibilité aux femmes d’assumer un rôle actif dans la communauté locale, tout en affirmant ses propres spécificités. Des sujets tels que la liberté religieuse sont abordés, et certains droits peuvent être réclamés par des individus qui ont ainsi acquis une position politiquement importante au sein de la société locale.

Blâmée par Jules Michelet, en raison d'un goût que l'historien du XIXe siècle estime trop prononcé pour les intrigues, Louise de Savoie (1476-1531) est sans conteste l'une des personnalités les plus fascinantes de la première Modernité européenne. Comtesse puis duchesse d'Angoulême, Louise n'est pas seulement la mère de deux illustres enfants, Marguerite et François, futur François Ier. Elle se charge de leur éducation ; une fois son fils devenu le roi de France, elle devient un conseiller des plus influents, avant d'assurer, à deux reprises, la régence du royaume. Amatrice d'art et bibliophile avertie, son action concerne encore la musique, la littérature et l'architecture. Les textes rassemblés dans cet ouvrage - issu d'un colloque tenu, en décembre 2010, à Romorantin-Lanthenay, où Louise possédait le château et des terres sur lesquelles Léonard de Vinci avait projeté d'édifier une ville nouvelle pour la cour - ambitionnent de passer en revue tant les aspects biographiques du personnage, que son action dans le champ politique, religieux et culturel.

Plants have a long evolutionary history, during which mass extinction events dramatically affected Earth’s ecosystems and its biodiversity. The fossil record can shed light on the diversi- fication dynamics of plant life and reveal how changes in the origination–extinction balance have contributed to shaping the current flora. We use a novel Bayesian approach to estimate origination and extinction rates in plants throughout their history. We focus on the effect of the ‘Big Five’ mass extinctions and on estimating the timing of origin of vascular plants, seed plants and angiosperms. Our analyses show that plant diversification is characterized by several shifts in origination and extinction rates, often matching the most important geological boundaries. The estimated origin of major plant clades predates the oldest macrofossils when considering the uncertainties associated with the fossil record and the preservation process. Our findings show that the commonly recognized mass extinctions have affected each plant group differently and that phases of high extinction often coincided with major floral turnovers. For instance, after the Cretaceous–Paleogene boundary we infer negligible shifts in diversification of non-flowering seed plants, but find significantly decreased extinction in spore-bearing plants and increased origination rates in angiosperms, contributing to their current ecological and evolutionary dominance.

Recent fieldwork has uncovered three new localities from the Lower Devonian of Mezquita de Loscos (Teruel Province, Spain) with further plant mega-fossils and the first record of micro-fossils. Such plant remains have been interpreted as belonging to a basal euphyllophyte, Taeniocrada-like stems, Hostinella genus and paired sporangia. Fourteen spore taxa were recovered, including Ambitisporites, Aneurospora, Brochotriletes, Chelinospora, Emphanisporites, Gneudnaspora and Retusotriletres, among others. New evidence confirms a Lochkovian age for this outcrop and suggests that the plant diversity was more complex than originally documented. © 2014 © 2014 Taylor & Francis. [less ▲]

In this paper, we show that the Triassic fossil record reflects just two great depletions of conodont diversity before the Rhaetian, which occurred in the Smithian (Olenekian, Early Triassic) and in the Julian (Carnian, Late Triassic). By exploring this context, our results highlighted that they respond to different origination-extinction dynamics. Thus, while the Smithian diversity depletion can be interpreted as a consequence of elevated extinction, the Julian diversity depletion was triggered by fluctuations in origination regime. This evidence suggests that, despite the role of extinction on diversity losses, conodonts suffered crucial changes on the origination regimes during the Late Triassic which triggered these events. Notwithstanding, our results indicate that the end-Triassic diversity depletion of conodonts was produced by background extinction levels in a context of lower origination. This suggests that several biological factors, rather than a unique, environmental and/or cyclic cause, could have influenced the evolutionary history of conodonts during the Triassic. © 2014 © 2014 Taylor & Francis.

Jatropha curcas oil has an insecticidal activity harnessed by the farmers in Niger. In this study, we compared the insecticidal activity of two batches of oil conserved during 70 days, one exposed to light and the other kept in the dark. The insecticidal efficacy was evaluated in a field with three concentrations (5, 10 and 15%) trial on the main pests of Cowpea (Vigna unguiculata (L.) Walp) and in a laboratory test on Megalurothrips sjostedti Trybon (Thysanoptera: Thripidae) with different concentrations of crude oil (50; 100; 150 and 200 µl). No difference in insecticidal effect was found between the two modes of oil conservation, both in the laboratory and in the field. In the field, regardless of the mode of conservation, the concentrations of 10% of J. curcas oil enables a reduction of over than 80% of thrips, aphids, and bugs compared to the control. Its increased seeds yield more than 50%. The concentration of 15% gives an insecticidal effect comparable to that of the reference treatment (deltaméthrine) but induces phytotoxicity symptoms on the leaves of Cowpea. [less ▲]

We revise the bound from the supernova SN1987A on the coupling of ultralight axion-like particles (ALPs) to photons. In a core-collapse supernova, ALPs would be emitted via the Primakoff process, and eventually convert into gamma rays in the magnetic field of the Milky Way. The lack of a gamma-ray signal in the GRS instrument of the SMM satellite in coincidence with the observation of the neutrinos emitted from SN1987A therefore provides a strong bound on their coupling to photons. Due to the large uncertainty associated with the current bound, we revise this argument, based on state-of-the-art physical inputs both for the supernova models and for the Milky-Way magnetic field. Furthermore, we provide major amendments, such as the consistent treatment of nucleon-degeneracy effects and of the reduction of the nuclear masses in the hot and dense nuclear medium of the supernova. With these improvements, we obtain a new upper limit on the photon-ALP coupling: g_{a\gamma} < 5.3 x 10^{-12} GeV^{-1}, for m_a < 4.4 x 10^{-10} eV, and we also give its dependence at larger ALP masses. Moreover, we discuss how much the Fermi-LAT satellite experiment could improve this bound, should a close-enough supernova explode in the near future. [less ▲]

Acute cardiorenal syndrome (CRS) corresponds to an association of acute heart failure and a worsening of renal function. The detection of acute kidney injury (AKI) unfortunately occurs at a late stage of CRS, leading to an increased mortality of the patients. In this review, we described the pathophysiology of CRS and discussed the potential interest of biochemical biomarkers (namely creatinine, cystatin C, NGAL, KIM-1, fatty acid binding protein, Nacetyl-β-D-glucosaminidase and IL-18) that could potentially help to detect AKI earlier and thus reduce the morbi-mortality of the patients suffering from CRS.

Background: Burn patients are at risk of vitamin D (VD) deficiency and may benefit from its pleiotropic effects as soon as acute phase. Aim of this observational study was to assess effects of a cholecalciferol (VD3) bolus on VD status in adult burn patients (Group B, GB) after admission, compared to healthy subjects (Group H, GH). Methods: Both groups received an oral dose of 100,000 IU VD3. Blood samples were collected before (D0) and 7 days (D7) after bolus to measure 250H-D, 1,25(OH)2-D, parathyroid hormone (PTH) and fibroblast growth factor 23 (FGF23). Albumin (ALB) and VD binding protein (DBP) were measured and used to calculate free 25OH-D level. Data were expressed as median (min–max) or proportions. Results: A total of 49 subjects were included: 29 in GH and 20 in GB. At D0, prevalence of VD deficiency was higher in GB: 25OH-D was 21.5 (10.1–46.3) ng/ml in GH vs 11 (1.8–31.4) ng/ml in GB. DBP and ALB were lower in GB. At D7, DBP was stable in both groups while ALB decreased in GB. 25OH-D increased by 66.6 (13.5–260.3)% in GH. In GB, changes in 25OH-D extended from 36.7% to 333.3% with a median increase of 33.1%. Similar changes were observed in each group for free 25OH-D. High FGF23 levels were observed in GB. Conclusions: This study highlighted the differences in VD status and in response to a high dose VD3 in burn patients when compared to healthy patients. Pitfalls in VD status assessment are numerous during acute burn care: 25OH-D measurement needs cautious interpretation and interest of free 25OH-D is still questionable. They should not prevent burn patients to receive VD supplements during acute care. Higher doses than general recommendations should probably be considered. [less ▲]
