Alternative reproductive strategies are widespread in caudate amphibians. Among them, fire salamanders (Salamandra salamandra) usually rely on streams to give birth to aquatic larvae but also use ponds, whereas palmate newt larvae (Lissotriton helveticus) typically metamorphose into terrestrial juveniles, but can also reproduce in retaining their gills, a process known as paedomorphosis. Here we report repeated observations of an unusual case of coexistence of these two alternative traits in the same pond (Larzac, France). The prevalence of fire salamanders in Southern Larzac was very low (pond occupancy: 0.36%). The observed abundance of fire salamander larvae and paedomorphic newts was also low in the studied pond. On one hand, the rarity of this coexistence pattern may suggest that habitat characteristics may not be optimal or that competition or predation processes might be operating. However, these hypotheses remain to be tested. On the other hand, as this is the only known case of breeding in Southern Larzac, it could be considered to be at a high risk of extirpation. [less ▲]

Il concerne plus spécifiquement l’article 138bis-4 de la loi belge, lequel règlemente les hausses tarifaires des contrats d’assurance maladie non liés à l’activité professionnelle. Dans un souci de protection du consommateur, le législateur a, en effet, choisi d’encadrer strictement les possibilités de hausses tarifaires de ce type de contrat. Interrogée à titre préjudiciel, la Cour est appelée à se prononcer sur la compatibilité de ce mécanisme avec le droit de l'Union. [less ▲]

In this work, we propose a simple yet effective solution to the problem of connectome inference in calcium imaging data. The proposed algorithm consists of two steps. First, processing the raw signals to detect neural peak activities. Second, inferring the degree of association between neurons from partial correlation statistics. This paper summarises the methodology that led us to win the Connectomics Challenge, proposes a simplified version of our method, and finally compares our results with respect to other inference methods.

Abstract Drawing on a documentary analysis of two socio-economic policy programs, one Flemish (“Vlaanderen In Actie”; VIA), the other Walloon (“Marshall Plans”; MPs), and a discourse analysis of how these programs are received in one Flemish and one Francophone quality newspaper, this paper illustrates how Flanders and Wallonia both seek to become top-performing knowledge-based economies (KBEs). The paper discerns a number of discursive repertoires, such as “Catching up,” which Flemish and Walloon policy actors draw on to legitimize or question the transformation of Flanders and Wallonia into KBEs. The “Catching up” repertoire places Flanders resolutely ahead of Wallonia in the global race towards knowledge, excellence, and science-driven innovation, but suggests that Wallonia may, in due course overtake Flanders as a top-competitive region. Given the expectations and/or fears that “Catching up” evokes among Flemish and Walloon policy actors, the repertoire serves these actors as a flexible discursive resource to make sense of, and shape, their collective futures, and thus their identities. By rendering explicit how Flanders and Wallonia each acquire a distinct identity through the global KBE, the paper underlines the simultaneity of, and the interplay between, globalizing forces and particularizing tendencies and illuminates the political, nation-building and identity-building functions of science, technology, and innovation. The paper starts from the following preliminary observations. While both the VIA plan and the MPs emphasize the need of transforming Flanders and Wallonia into KBEs in order meet the demands of globalization (OECD 1996), the plans adopt a different tone and stance. The Flemish plan repeatedly states the need of transforming Flanders into “a top region, not only in Europe, but in the world, particularly in the social and economic field” (VIA, 2006: 4). It also states that Flanders is already prosperous and already has many strengths, but that the welfare and prosperity of Flanders are “under threat” in a “challenging global economic environment” (2). The message is thus that Flanders is doing relatively well in the global economy, but that it must do even better if it is to maintain its competitive edge and its welfare. By contrast, the MP is framed from the perspective of Walloon recovery and “redressement.” Although the term “Marshall Plan” evidently brings to mind the European Recovery Program for rebuilding Western Europe after World War II, recovery also refers to the period of prosperity before the World Wars, when Wallonia was one of the most economically advanced industrial regions in Europe. The MP suggests that Wallonia’s glorious past (“le passé glorieux”) can be rewon, if the Walloons deploy every tool they can muster and work together to “relaunch” the Walloon economy (3). To incite joint action, the MP urges the Walloons to become the architects of their own fate. This aspiration is clearly expressed in the opening sentence of the first MP plan: “The federalization [of Belgium; by which is meant the regionalization of policy and competences] bestows the Walloons with political autonomy, which renders them responsible for their own destiny.” At the same time, this statement reads as a call to independence, as the Walloons are bestowed with political autonomy (by the Flemings, who have repeatedly pushed for the dismantling of Belgium as a unitary state). As the above excerpts from the Flemish and Walloon policy plans indicate, VIA and the MPs characterize a state of political and economic affairs, take position in relation to these affairs, and, most importantly, envision a prosperous future for the Flemish and Walloon region, respectively. The plans are thus driven by expectations, visions and values, as well as fears. They mobilize arguments, explanations, evaluations, descriptions and prescriptions, sometimes by drawing on tropes or stereotypes, anecdotes, and illustrations. As the plans also indicate, transforming Flanders and Wallonia into top KBE regions does not happen by itself. For instance, while the VIA plan describes Flemings as entrepreneurs, it also states that “we must dare to be entrepreneurial” (3). Similary, the MP urges Walloon citizens to change their “état d’esprit” or mindset, if economic growth is to ensue (3). Thus, identity construction and transformation are in order both in Flanders and in Wallonia. The above observations serve as starting points for our media analysis. As we want to know whether, and how, these particular conceptions of the nation/region are picked up in press reporting on STI policies, we ask the following interrelated questions: How are the Flemish (VIA) and Walloon STI policies (MPs) received in the Flemish and Francophone press? Do we discern in the press the same notions of identity as in the policy programs? Are these notions reproduced, problematized or transformed? If so, in what ways? What does this mean for Flemish and Walloon identity construction, and for the construction of “Belgium” at large? Recognizing the role of “institutions of power” (e.g. language, media, technologies) in articulating nationalism (Anderson 1991: 163; Billig 1995: 11), our analysis conceives of journalists and the press as potential policy agenda setters and opinion makers, as the press potentially reproduces and redefines political identities. As this paper will illustrate, the Flemish and Francophone press speak out on issues of collective identity and also offer various policymakers a platform to express their views on regional economic development, STI, and the state. Thus, from our perspective, policymaking is not only the prerogative of mandated policymakers, but of journalists and other opinion leaders (e.g. captains of industry) as well (Lenschow & Sprungk 2010). To enable analysis, we draw on a range of literatures, including science and technology studies, discourse analysis, and media analyses. Our approach is interpretive and interactionist, as it assumes that realities (e.g. identities, nations, as well as practices and materialities) are socially constructed rather than exist as objective phenomenon that can be discovered through empirical testing (Fischer 2003: 118). Hence, we ask how identity is created, structured, maintained, or conversely deconstructed, resisted, and challenged. Our aim is thus not to uncover an objective reality behind identity, but to understand how identities are collectively made and remade on a continuous basis. To this end, we draw on the notion of “coproduction” (Jasanoff 2006: 2) to empirically demonstrate how STI and nationalism are “coproduced” through technoscientific practices (Felt 2013). In what follows, we first present, discuss, and situate Flemish and Walloon STI policies in time and place, as a means of contextualizing the “nationalisms” inscribed in the VIA plan and MPs. Next, we present our methodological framework for discourse and media analysis, our data, and key findings. Upon drawing together these findings, we single out the storyline of “Catching up” as an important discursive backdrop against which processes of collective identity construction play out through STI policymaking and press reporting. We conclude by tying our findings into a broader discussion about the place of Belgium in Europe and the world, as nation states are constantly (re)defined in terms of their constituent segments and overarching structures, including the KBE. The paper’s topics resonate with the overall conference theme and specifically tie into the following conference strands: • Policy emergence, implementation, diffusion and transfer • National science policies and the global scientific enterprise • The multi-level governance of research and innovation and the challenge of co-ordination Keywords: Flanders, Identity, Knowledge-based economy, Science and technology policy, Wallonia.

The first resonance frequency is a key performance characteristic of MEMS vibrometers. In batch fabrication, this first resonance frequency can exhibit scatter owing to various sources of manufacturing variability involved in the fabrication process. The aim of this work is to develop a stochastic multiscale model for predicting the first resonance frequency of MEMS microbeams constituted of polycrystals while accounting for the uncertainties in the microstructure due to the grain orientations. At the finest scale, we model the microstructure of polycrystaline materials using a random Voronoï tessellation, each grain being assigned a random orientation. Then, we apply a computational homogenization procedure on statistical volume elements to obtain a stochastic characterization of the elasticity tensor at the second scale of interest, the meso-scale. In the future, using a stochastic finite element method, we will propagate these meso-scale uncertainties to the first resonance frequency at the coarser scale. [less ▲]

The aim of the study was to validate the use of electromyography (EMG) for detecting responses to command in patients in vegetative state/unresponsive wakefulness syndrome (VS/UWS) or in minimally conscious state (MCS). Methods: Thirty-eight patients were included in the study (23 traumatic, 25 patients >1 year post-onset), 10 diagnosed as being in VS/UWS, eight in MCS- (no response to command) and 20 in MCS+ (response to command). Eighteen age-matched controls participated in the experiment. The paradigm consisted of three commands (i.e. 'Move your hands', 'Move your legs' and 'Clench your teeth') and one control sentence (i.e. 'It is a sunny day') presented in random order. Each auditory stimulus was repeated 4-times within one block with a stimulus-onset asynchrony of 30 seconds. Results: Post-hoc analyses with Bonferroni correction revealed that EMG activity was higher solely for the target command in one patient in permanent VS/UWS and in three patients in MCS+. Conclusion: The use of EMG could help clinicians to detect conscious patients who do not show any volitional response during standard behavioural assessments. However, further investigations should determine the sensitivity of EMG as compared to neuroimaging and electrophysiological assessments. [less ▲]

In this work, a follow up of the changes in populations size, and the rates of inbreeding of the Belgian poultry breeds, has been carried out in 2005 and 2010. About forty breeds were concerned. The Belgian hen breeds being overwhelmingly under threat of extinction, because of the low number of individuals by breed. For each of these breeds, various criteria were considered, risk status, breeding male to breeding female ratio, effective population size, effective population size to actual size ratio and rate of inbreeding.
