Analogical reasoning development maintains a mutual influence with language acquisition: the use of relational labels helps to resolve analogical reasoning tasks (Christie & Gentner, 2014) while analogical reasoning enables the acquisition of new linguistic concepts or structures (Gentner & Namy, 2006). This link has driven some authors to examine the analogical reasoning ability of children with Specific Language Impairment. Those children have poorer analogical reasoning performance than their age-matched peers without language disorders (Leroy et al., 2012 ; Leroy et al., 2014). So, children with SLI seem to have an analogical reasoning weakness which could be linked to their language disorders. Thus, our goal here is to measure the ability of children with SLI to solve analogies, and to compare it to chronological age-matched but also to linguistic age-matched peers without language disorders. Our hypotheses here are the followings: children with SLI have weaker analogical reasoning competence compared to chronological age-matched peers and similar or weaker analogical reasoning competence compared to language-matched peers. To test these hypotheses, we use a scene analogy task composed of pictures of 20 relations (Richland et al., 2006) varying in relational complexity (binary or ternary relations) and in perceptual distraction. Twenty children with SLI are matched to chronological age and linguistic age peers without language disorders. Children with SLI have poorer performance then their age-matched peers but they have similar performance to their language-matched peers. This data reinforces the idea of a link between analogical reasoning and language, also in children with SLI. However, the nature of this link should still be clarified. [less ▲]

Genau wie bei allen anderen Bestandteilen Belgiens ist auch das Erscheinungsbild der Deutschsprachigen Gemeinschaft durch die sechste Staatsreform grundlegend verändert worden. Sie verfügt fortan über die konstitutive Autonomie – das bedeutet, die Funktionsweise ihrer Regierung und ihres Parlamentes zu regeln. Vor allem hat sich ihr Handlungsspielraum im Bereich der kulturellen und personenbezogenen Angelegenheiten ebenso wie bei der Französischen und Flämischen Gemeinschaft erweitert: Familienleistungen, Gesundheitsversorgung, Personenbeistand, Justizhaus, elektronische Überwachung, Industrielehre, … Zudem hat die Wallonische Region ihr die Ausübung neuer Zuständigkeiten im Bereich des Tourismus, der Beschäftigung und der Gemeinden übertragen. Der vorliegende Courrier hebdomadaire macht eine Bestandsaufnahme der Zuständigkeiten sowie der Finanzierung der Deutschsprachigen Gemeinschaft und identifiziert dabei die Veränderungen, die die sechste Staatsreform in dieser Hinsicht gebracht hat. Er geht auf die politischen Debatten ein, die diese Reformen begleitet haben und auf die Art und Weise, wie diese bereites teilweise umgesetzt worden sind. Er rekapituliert auch wie die Deutschsprachigen Gemeinschaft innerhalb der Europäischen Union, auf föderaler Ebene, innerhalb der Wallonischen Region und in der Provinz Lüttich vertreten wird . Die Studie zeigt die Perspektiven auf, die sich der Deutschsprachigen Gemeinschaft in Zukunft eröffnen. Diese fordert dabei zum einen, die Gesamtheit der regionalen und provinzialen Zuständigkeiten auf ihrem Gebiet ausüben zu können und zum anderen, einen sichtbareren Platz in der institutionellen Architektur des Landes einzunehmen. Da diesen Ansprüchen bislang nicht nachgekommen wurde, möchten die deutschsprachigen politischen Verantwortlichen die Diskussion im Laufe der kommenden Jahre wieder aufgreifen. [less ▲]

This paper focuses on simplified models of the Modular Multilevel Converter suitable for large-scale dynamic studies, in particular simulations under the phasor approximation. Compared to the existing literature, this paper does not a priori adopt the modeling approach followed for the original twolevel or three-level Voltage Source Converter. On the contrary, a model is derived following a physical analysis that preserves its average internal dynamic behavior. An equivalent control structure is proposed and various alternatives are highlighted. The proposed model with its controllers has been implemented in a phasor simulation software and its response has been validated against a detailed Electromagnetic Transient model. Finally, an illustrative example is presented with the application of the proposed model on a large grid consisting of AC areas interconnected with a multi-terminal DC grid. [less ▲]

The in-control performance of the Shewhart X ̅ and S2 control charts with estimated in-control parameters has been evaluated by a number of authors. Results indicate an unrealistically large amount of Phase I data is needed to have the desired in-control average run length (ARL) value in Phase II. To overcome this problem, it has been recommended that the control limits be adjusted based on a bootstrap method to guarantee that the in-control ARL is at least a specified value with a certain specified probability. In our paper we present simple formulas for the required control limits so that practitioners do not have to use the bootstrap method. An assumption of normality is required. The advantage of our proposed method is in its simplicity; there is no bootstrapping and the control chart constants do not depend on the Phase I sample data. [less ▲]

OBJECTIVES: To describe the results of a prevention campaign in terms of participation and pet health status and to identify opportunities to improve preventive medicine in cats and dogs. METHODS:An awareness campaign was designed to highlight the role of veterinarians and emphasise the benefits of a veterinary visit. Owners were invited to make an appointment for a free pet health check in a voluntarily participating veterinary clinic. Observations recorded by the veterinarians were entered in a database and subsequently analysed using simple descriptive statistics. RESULTS:A total of 5305 completed health check forms were analysed. The percentages of overweight and obese dogs and cats were 34 and 36%, respectively; this was the most common finding, followed by dental calculus (31% in dogs, 21% in cats). In total 67% of cats did not undergo flea control and 59% were not vaccinated. CLINICAL SIGNIFICANCE: Opportunities for increased quality of care are numerous given the high percentage of intact, unvaccinated or non-permanently identified pets and the low level of worm and flea control. Animal health should benefit from preventive measures, and improved management can be undertaken after early detection of diseases. [less ▲]

The development of high-order computational methods for solving partial differential equations on unstructured grids has been underway for many years. Such methods critically depend on the availability of high-quality curvilinear meshes, as one bad element can degrade the solution in the whole domain. The usual way of generating curved meshes is to first generate a (high-quality) straight-sided mesh. Then, mesh entities that are classified on the boundaries of the domain are curved. This operation introduces a "shape-distortion" that should be controlled. Quality measures allow to quantify to which point an element is well-shaped. They also provide tools to improve the quality of meshes through optimization. In this work we propose an efficient method to compute several quality measures for curved elements, based on the Jacobian of the mapping between the straight-sided elements and the curved ones. Contrary to the approach presented in "A. Gargallo-Peiró, X. Roca, J. Peraire, and J. Sarrate. Distortion and quality measures for validating and generating high-order tetrahedral meshes. Engineering with Computers, pages 1–15, 2014.", which relies on an L2-norm over the elements, we compute the actual minimum and maximum of the local quality measure for each element. The method is an extension of previous works on the validity of those elements (A. Johnen et al., 2013). The key feature is that we can adaptively expand functions based on the Jacobian matrix and its determinant in terms of Bézier functions. Bézier functions have both properties of boundedness and positivity, which allow sharp computation of minimum or maximum of the interpolated functions. [less ▲]

This paper looks at the relationship between higher education ministers and the performance of the sector that they govern. Using an original panel dataset with the characteristics of European higher education ministers, we find that having a past experience in the sector leads to a higher level of performance, as measured by ranking data. Making a parallel with the literature about the impact of education on the educated, we discuss potential explanations behind the impact of this on-the-job learning experience. As we find that this characteristic has no impact on the spendings of the sector, we argue that this academic experience makes them more prone to introduce adequate reforms that makes the sector more attractive for top-researchers. Furthermore, we find that this result is driven by ministers with both sector-specific and electoral experience, the latter measured by a successful election at the regional or national level. This tends to show that political credibility should not be overshadowed by the importance of the sector-specific experience of ministers. [less ▲]

Studies conducted these last two decades have revealed that high sea surface temperatures accompanied by high levels of solar irradiance are responsible for an over production of reactive oxygen species (ROS) leading to the disruption of the symbiosis between cnidarians and their symbiotic Symbiodinium. But, all coral species do not show the same sensitivity to stress. In this context we examined how the antioxidant network of different Symbiodinium species responds to oxidative stress. We bypassed the various thermal and light tolerances existing among the genus Symbiodinium by using a chemical approach, i.e., a treatment with menadione. ROS produced during this oxidative burst reduced photosynthesis by 30 to 50% and significantly decreased the activity of superoxide dismutase. In addition, the low level of lipid peroxidation concomitantly with the decrease in the concentration of diatoxanthin and other carotenoids during the oxidative stress confirms their function of antioxidants and their role in the stabilization of membrane lipids. The analysis of the cellular damages also indicates that proteins were damaged and most likely eliminated by the ubiquitin-proteasome pathway. Finally, caspase-like activity decreased suggesting that cell death mechanisms are not initiated at the early stage of the stress. Although, the mechanisms at play seem to be the same, we found that the temperate Symbiodinium strain (A1) was less impacted by the treatment with menadione than the tropical strain (F1) suggesting that the variations observed are related to their geographic origin.
