The WHO (2015) estimates to 1 million deaths par year due to physical inactivity in Europe. The promotion of children physical activity is the starting point as active children are more likely to remain active in adulthood than the others (ACSM et al., 2015). According to ecological model (Booth, 2001) school and teachers are essentials determinants to encourage children in this way. Then, we decided to implement a unit aiming to train physical education students to be able to counselling children and sedentary people. The first step was to interview 15 field professionals supposed to be involved in physical activity promotion in order to identify the essential factors to point out. The second step was to design a formation plan allowing to fill gaps in students skills. The last point will be to implement this formation and to analyse the impact on students actions. [less ▲]

Growth curves of four species of green microalgae have been compared under photoautotrophy, heterotrophy and dim-light-assisted heterotrophy during batch cultivation in small-scale multicultivators equipped with automated optical density acquisition. The results showed that the most relevant biomass productivity parameter (based on Vmax) can be estimated after proper correction of growth curves. For photoautotrophic cultures, Vmax showed no clear relationship to µmax, the specific growth rate measured during exponential phase. Heterotrophic cultures, which are not limited by light penetration, can be characterized by their µmax values, which showed a broad range of values depending more on species than on carbon source (glucose or acetate). Weak light (defined as unable to sustain photoautotrohic growth) had only minor effects on heterotrophic growth in terms of biomass but, for some species, could be used to promote pigment accumulation up to levels comparable to those found under photoautotrophy, as revealed by HPLC analysis.

This presentation will focus on both didactic and pedagogical reflections teaching mathematics in architecture programme in order to support the experience and learning of first year students. Led in order to promote the students’ intrinsic motivation (Deci & Ryan, 1985) and support our didactic reflections, an inventory of mathematical difficulties encountered by freshmen in their program has been established. This inventory also served the purpose of demystifying mathematics and valuing them through a place in a cursus more rooted in the profession (Wigfield and Eccles, 2000). Sorted according to the skills involved, the relevant difficulties pointed out by students were mostly found in two courses, topography and structure. Several examples will be presented demonstrating the lack of transfer between the disciplines, students studying formulas without understanding them. To counter this lack of transfer, pedagogical reflections about our current teaching were developed thanks to the Feedback First-Year Project (FFYP) developed in the University of Liège. In this context, three significant devices set up in mathematics were developed. The first one is an online-oriented prerequisite test implemented on our academic online platform. The second one is an intermediate test based on true/false quizzes and the third one a simulation of the real exam with peer interventions. According to Nicol’s recommendations (2009), each of these features is completed with specific feedbacks specially designed in order to impact several dimensions of their motivation. [less ▲]

Purpose: This paper describes the theoretical background and main hypotheses at the basis of SAFIR®, a nonlinear finite element software for modeling structures in fire. The paper also explains how to use the software at its full extent. The discussed numerical modeling principles can be applied with other similar software. Approach: Following a general overview of the organization of the software, the thermal analysis part is explained, with the basic equations and the different possibilities to apply thermal boundary conditions (compartment fire, localized fire, etc.). Next, the mechanical analysis part is detailed, including the time integration procedures and the different types of finite elements: beam, truss, shell, spring and solid. Finally, the material laws are described. The software capabilities and limitations are discussed throughout the paper. Findings: By accommodating multiple types of finite elements and materials, by allowing the user to consider virtually any section type and to input the fire attack in multiple forms, the software SAFIR® is a comprehensive tool for investigating the behavior of structures in the fire situation. Meanwhile, being developed exclusively for its well-defined field of application, it remains relatively easy to use. Value: The paper will improve the knowledge of readers (researchers, designers and authorities) about numerical modeling used in structural fire engineering in general and the capabilities of a particular software largely used in the fire engineering community.

Background Migraine is a complex multifactorial disease that arises from the interaction between a genetic predisposition and an enabling environment. Habituation is considered as a fundamental adaptive behaviour of the nervous system that is often impaired in migraine populations. Given that migraineurs are hypersensitive to light, and that light deprivation is able to induce functional changes in the visual cortex recognizable through visual evoked potentials habituation testing, we hypothesized that regional sunlight irradiance levels could influence the results of visual evoked potentials habituation studies performed in different locations worldwide. Methods We searched the literature for visual evoked potentials habituation studies comparing healthy volunteers and episodic migraine patients and correlated their results with levels of local solar radiation. Results After reviewing the literature, 26 studies involving 1291 participants matched our inclusion criteria. Deficient visual evoked potentials habituation in episodic migraine patients was reported in 19 studies. Mean yearly sunlight irradiance was significantly higher in locations of studies reporting deficient habituation. Correlation analyses suggested that visual evoked potentials habituation decreases with increasing sunlight irradiance in migraine without aura patients. Conclusion Results from this hypothesis generating analysis suggest that variations in sunlight irradiance may induce adaptive modifications in visual processing systems that could be reflected in visual evoked potentials habituation, and thus partially account for the difference in results between studies performed in geographically distant centers. Other causal factors such as genetic differences could also play a role, and therefore well-designed prospective trials are warranted. [less ▲]

In Belgium, there is a particular group of music teachers referred to as music theory teachers. Working at music schools, they convey theoretical knowledge and practical musical skills to groups of individuals who learn music during their free-time. Even though music theory teachers use both speaking and singing voice intensively at work, little is known about their voice use profiles. This study investigated the vocal loading among French-speaking music theory teachers. Objectives were (1) to describe their professional and extra-professional vocal loading, (2) to determine the relationship between vocal loading and background noise level and (3) to investigate whether objectively measured vocal loading is reflected in music theory teachers’ auto-evaluation of their voice. Using voice dosimetry, 13 music theory teachers were monitored for one workweek. Parameters analysed were F0, voice sound pressure level (SPL), phonation time, vocal loading index (VLI) and background noise SPL. At the end of each monitoring day, subjects self-assessed their voice use by means of visual analogue scales. Results revealed (1) significantly higher vocal loading in the professional context than in the extra-professional context, (2) significant positive correlations between background noise level and the parameters F0, voice SPL and phonation time and (3) significant correlations between the VLI and auto-evaluation data (e.g. voice quality and vocal fatigue). These results highlight that teaching music theory is a profession with high vocal demands. At work, music theory teachers are exposed to high background noise, which seems to influence their voice use and may potentially contribute to the development of voice problems among this population. Visual analogue scales provide a promising tool to subjectively investigate vocal loading among music theory teachers. [less ▲]

Twentieth century regional sea-level changes are estimated from 12 climate models from the 5th phase of the Climate Model Intercomparison Project (CMIP5). The output of the CMIP5 climate model simulations were used to calculate the global and regional sea-level changes associated with dynamic sea level, atmospheric loading, glacier mass changes and ice sheet surface mass balance contributions. The contribution from groundwater depletion, reservoir storage and dynamic ice sheet mass changes are estimated from observations as they are not simulated by climate models. All contributions are summed, including the GIA contribution, and compared to observational estimates from 27 tide gauge records over the twentieth century (1900-2015). We find a general agreement between the simulated sea level and tide gauge records in terms of inter-annual to multi-decadal variability over 1900-2015. But climate models tend to systematically underestimate the observed sea-level trends, particularly in the first half of the 20th century. The corrections based on attributable biases between observations and models that have been identified in the part-1-paper, result in an improved explanation of the spatial variability in observed sea-level trends by climate models. Climate models show that the spatial variability in sea-level trends observed by tide-gauge records is dominated by the GIA contribution and the steric contribution over 1900-2015. Climate models also show that it is important to include all contributions to sea-level changes as they cause significant local deviations; for example, the groundwater depletion around India which is responsible for the low 20th century sea-level rise in the region.

After taking into account the requirements from all the disciplines at work as well as the problems that would have to be tackled, the creation of a 3D point cloud was decided. This solution would be able to deal with the characteristics and needs of a research involving building archaeology and related fields. The decision was made in order to manage all of the available data and to provide a common working tool for every involved cultural heritage actor. [less ▲]

La présente contribution envisage l’oral réflexif tel qu’il se décline dans les journaux des apprentissages. Dans plusieurs classes d’école primaire ou secondaire, en France, en Belgique, au Québec, au cours ou au terme de leur journée de classe, des élèves prennent la plume pour écrire dans un cahier à propos de leurs apprentissages, de leurs difficultés, de leurs incompréhensions, de leurs stratégies d’apprentissage, de leurs modes de résolution de problèmes, mais aussi à propos des relations interpersonnelles nouées à l’école, des tâches prescrites par l’enseignant ou de ses pratiques pédagogiques. Tout aussi inlassablement, les enseignants dialoguent avec les enfants en commentant, interrogeant, discutant les annotations des scripteurs dans leur cahier. Ils lisent et écrivent, ils réajustent les projets pédagogiques en fonction des textes lus. Au début de la journée, un enfant est invité à lire devant la classe le texte qu’il a rédigé la veille. Les pairs et l’enseignant écoutent le texte ainsi livré à tous, ils le commentent le cas échéant. On le voit, le dispositif du journal d’apprentissage associe étroitement oral et écrit réflexifs. Cette contribution s’attachera à dégager l’articulation du scriptural et de l’oral au cœur et autour du journal des apprentissages. Nous tenterons d’abord de mieux cerner le genre « journal des apprentissages » sur le plan des pratiques langagières orales et scripturales qu’il sollicite et contribue à construire chez l’élève. Nous verrons si une délimitation nette peut être tracée entre les unes et les autres. Ensuite, nous analyserons les annotations des scripteurs consacrées aux tâches orales réalisées en classe, ce qui permettra d’identifier comment l’oral est mobilisé ou enseigné dans les classes de l’échantillon, mais aussi d’analyser la réception des activités orales auprès des apprenants. Notre corpus est international et compte près de deux-cents journaux tenus par des enfants du primaire et des adolescents du secondaire, dans des contextes contrastés. [less ▲]

Polyvinylamine (PVAm) presents valuable properties like affinity for many supports, pH responsiveness, metal binding capacity, polyelectrolytes complexation, and is used in various applications including coatings, water purification or gas membrane separation. PVAm is commonly prepared by free radical polymerization of N-vinyl monomers followed by deprotection and release of the masked amino functions. However, examples of controlled synthesis of polyvinylamine-based copolymers are scarce because of the high reactivity of the propagating radicals deriving from non-conjugated N-vinyl monomers due to the lack of resonance stabilization. The present communication aims at reporting an efficient platform for producing tailor-made PVAms via organometallic-mediated radical polymerization (OMRP) of N-vinylacetamides followed by hydrolysis of the pendent amide moieties. In this case, cobalt(II) acetylacetonate was successfully used as controlling agent. The synthesis of a series of well-defined homopolymers, statistical and block copolymers with pendent primary and/or secondary amines having low dispersities, predictable molar masses and precise compositions, will be described. Finally, we will discuss the possible use of these polyvinylamine-containing copolymers as gene transfection agents. Some of them demonstrated high DNA transfection level in combination with high cell viability. [less ▲]

As defined by Jenkins (2006), transmedia storytelling is intimately linked with creative practices of reception which take part in what we now call the “participatory culture” (Raessens, 2005; Jenkins, 1992 and 2009). The audience plays, indeed, a key role in the construction of transmedia universes, given that “to fully experience any fictional world, consumers must assume the role of hunters and gatherers, chasing down bits of the story across media channels, comparing notes with each other via online discussion groups, and collaborating to ensure that everyone who invests time and effort will come away with a richer entertainment experience” (Jenkins, 2006: 21). Consequently, studying a media – in this case, the video game – through the lens of transmedia storytelling urges one to take into consideration how the public can participate, feed, or transform fictions by consuming them. Furthermore, in the field of game studies, it is all the more relevant to deal with the implication of players in the creative process since video games are historically and structurally related to the practice of misappropriation or detournement. As Genvo notes: “the creation of the first video game [Spacewar, 1962] already resulted from a playful act, which was expressed by the misuse of the conventional function of an MIT’s super calculator” (Genvo, 2008: 2). This original affinity now appears in a number of creative practices that prolong the game outside its primary space and enable it to seep into other medias: as fanfictions, modding or machinimas show, the video game is regularly apprehended by players not as a closed work to consume, but “more as [a] suit[e] of resources to be played with” (Newman, 2012: 123). This paper therefore seeks to study the impact of players’ misappropriations on the development of video games' fictional worlds. In this perspective, I will focus on a deeply transmedia license, the Pokémon saga, and on two creative practices that reconfigure games’ universes: fanarts and fanfictions. While amateur drawings and comics inspired by Pokémon GO have created narrative extensions from scratch about the barely characterized Team Leaders (Blanche, Candela and Spark), fan-authors have written thousands of texts that play with elements of the Pokémon universe in order to produce original stories. Yet, these textual and pictorial rewritings do not merely reuse narrative elements of Pokémon games; they also feature strictly playful components such as gameplay, glitches or actions like saving and reloading, which then become new types of narrative motifs. Fanfictions and fanarts thus construct – like the games they extend – hybrid fictions, mixing storytelling and gaming logic: in Amato’s words, “ludiegesis” (Amato, 2005 : 301). Using theoretical tools from narratology and from game studies, I will show that, by reincorporating playful aspects in their narrative structures, these derivative works hold a reflexive discourse on the original game that cannot be reduced to a binary opposition between “adhesion” and “subversion”, but which builds a whole new stratum of fiction.

In this presentation, we discuss the role of citizen science in the governance of nuclear incidents/accidents in emergency preparedness, response and post-disaster recovery. Starting from the 2011 Fukushima nuclear disaster, we (1) trace the expansion of citizen science in the nuclear field to other countries and contexts; (2) ask how citizen-science concepts, methods, and toolsets challenge institutional approaches to preparedness and response to nuclear incidents/accidents and post-disaster situations; and how nuclear safety authorities respond to such challenges; (3) probe the possibilities of incorporating citizen-science concepts and practices into Belgian and European approaches to nuclear emergency response, preparedness, and recovery. Our research draws on qualitative methods in Interpretive Policy Analysis and Science and Technology Studies to highlight the contentious politics that characterize interactions between citizen scientists and nuclear authorities in Japan and other countries. It anticipates the emergence of hybrid citizen-science forms, comprising material artifacts (e.g. new radioactivity measurement devices) and discourses (e.g. on the role of science in society), which simultaneously challenge and accommodate institutional approaches to nuclear emergency preparedness and response. By comparing citizen-science initiatives in Japan and Belgium, the project sheds light on citizen science as an emerging pattern of governance and probes its problem-solving capacities and long-term viability.
