In this presentation, we will focus on the Fuji Five Lakes region. Since 2013, Mt. Fuji and the Fuji Five Lakes area (Lake Motosu, Lake Shoji, Lake Sai, Lake Kawaguchi and Lake Yamanaka) are added on the world heritage list of UNESCO. Mt. Fuji is a main touristic attraction in Japan bringing each year 300 000 tourists. The Fuji Five Lakes are located at the foot of Mt. Fuji Volcano close to the triple junction where the North American Plate, the Eurasian plate and the Philippine Sea Plate meet. Therefore, the region can be impacted by Mt. Fuji volcanic eruption as well as by large magnitude earthquakes. Additionally, nearly every year, Japan is hit by strong winds, heavy rains with flood, landslides and high waves. These natural hazards may affect the Japanese economy by causing casualties and infrastructure damage. In the regions frequently affected by natural disasters like Japan, it is crucial to have a better knowledge of the recurrence times of such disasters in order to refine the probabilistic models. For that purpose, lacustrine sediments are often used. Lacustrine sediments retrieving by coring offer several advantages compared to onland drilling: the method is cheaper, the cores are easier to take and they have longer temporal span. Lacustrine sediments are generally good archives to record past natural hazards. However, each lake has its own particular setting and a different sensitivity to record paleohazards. Coupling geophysical data, sedimentological analysis and historical records is often required to identify natural paleohazards in the sedimentary records and to define the threshold sensitivity of the lake. Here, we will used Fuji Five Lakes as natural laboratory for the recording of paleohazards (typhoons, earthquakes and volcanic eruptions) and will discuss the sedimentary record of Lake Motosu, Lake Sai, Lake Yamanaka and Lake Kawaguchi over the last ca. 6000 years regarding their geomorphological characteristics.

In the framework of the CORDEX.be project funded by Belspo, most universities and research institutes of Belgium have worked together in order to gather existing and ongoing Belgian research activities in the domain of climate modelling to create a coherent scientific basis for future climate services in Belgium. The Laboratory of Climatology of the University of Liège has performed climate simulations using the regional climate model MAR (“Modèle Atmosphérique Régional” in French) at a resolution of 5 km over the period 1959-2014. This research aims to study the evolution of several variables computed by MAR during the winters of the last 50 years. Except in snow accumulation, results show no statistically significant trend in winter temperature or precipitation in Belgium. This results from the strong influence of natural large-scale/low-frequency oscillations in the atmospheric circulation in winter such as the North Atlantic Oscillation. [less ▲]

Les boitiers de vote font l’objet de très nombreux articles. Les auteurs cherchent par exemple à voir si l’utilisation de cet outil a un effet sur la motivation des étudiants et leur participation au cours (Caldwell, 2007), sur leur engagement (Mc Gowan et Gunderson,2010), sur le climat de classe (Bain et Przybyla, 2009) ou encore sur les apprentissages qu’ils réalisent (Preszler et al., 2007). Au final, comme souvent lorsqu’il s’agit de technologie, il semble que ce soit la pédagogie supportée par l’outil qui fasse la différence : l’usage sera pertinent s’il entre en résonance et en concordance avec une pédagogie efficace. Certes, l’outil en lui-même peut avoir un effet sur la pédagogie. Influencer, de par son fonctionnement - les possibilités qu’il offre, parfois les contraintes qu’il fait peser - la manière de concevoir des dispositifs pédagogiques. Il peut ainsi modifier le rapport des enseignants à leur pédagogie, c’est-à-dire, finalement, stimuler ou catalyser le développement professionnel des enseignants dans le domaine de la pédagogie universitaire. L’effet de l’outil et de son usage sur ce développement professionnel est au cœur de notre article. En effet, nous avons greffé - sur deux dispositifs d’accompagnement technopédagogique d’enseignants novices dans le domaine des BVE - un dispositif de recherche observant l’effet de cet usage accompagné. L’un de ces dispositifs d’accompagnement était court : l’enseignant est interviewé à deux reprises et observé lors d’une séance de cours durant laquelle les BVE sont utilisés. L’autre est plus long et comprend des autoconfrontations, des interviews, le recueil de l’avis des étudiants… La méthodologie utilisée dans cette étude, de type qualitatif, confirme notre intuition de départ : l’usage accompagné de BVE chez des enseignants novices peut, sous certaines conditions dont nous ferons état lors de la communication, accélérer le développement professionnel de ces derniers.

La présente communication est issue d’une recherche plus globale visant à identifier et à mieux comprendre les pratiques d’évaluation des acquis des étudiants auxquelles recourent les enseignants de l’enseignement supérieur et en particulier les facteurs personnels (ancienneté, attitudes vis-à-vis de l’évaluation…) et contextuels (année d’étude, taille du groupe, disciplines…) qui influencent ces pratiques. Les données ont été recueillies en 2016, d’une part, via une enquête en ligne (élaborée à l’aide du logiciel d’enquêtes Qualtrics) auprès d’enseignants de l’enseignement supérieur belge francophone que ce soit à l’Université ou en Hautes écoles (2292 réponses) et, d’autre part, via 37 entretiens semi-structurés individuels réalisés auprès d’un échantillon de ces mêmes enseignants dans des filières d’études contrastées. Les résultats présentés dans le cadre de cette communication ont trait à l’impact de deux variables personnelles : l’ancienneté des enseignants et leurs attitudes vis-à-vis de l’évaluation. Autrement dit, on cherchera à savoir si l’ancienneté et le développement professionnel qui l’accompagne traditionnellement ont des incidences sur le type de pratiques d’évaluation des acquis des enseignants. En particulier, recourent-ils à des outils de plus en plus diversifiés ou ont-ils tendance à se spécialiser dans l’un ou l’autre ? Et si oui, pourquoi ? Accentuent-ils par ailleurs le recours à l’évaluation continue par rapport au poids du contrôle terminal ? On cherchera ensuite à comprendre comment les pratiques se reconfigurent en fonction des attitudes des enseignants vis-à-vis de l’évaluation et en particulier vis-à-vis de sa fonction et de son rapport à l’apprentissage : dans quel sens une conception davantage intégrative de l’évaluation colore-t-elle les pratiques déclarées d’évaluation ?

HTLV-1 (Human T-cell Leukemia Virus) is the etiologic agent of human adult T-cell leukemia (ATL) and tropical spastic paraparesis (TSP). More than 20 million people worldwide are infected with the HTLV-1 virus, but only about 5 % develop the associated pathologies. At present, efforts are invested in the search for treatments that may improve the survival expectancy of patients infected by the HTLV-1 virus. The diagnosis of HTLV-1 infection is hampered by the viral genome latency (up to 40 years) and treatment options are limited. To propose novel therapeutic opportunities, it thus is necessary to better understand the host molecular mechanisms perturbed by the HTLV-1 infection. The HTLV-1 genome encodes for the Tax-1 protein, which confers the transforming ability of the virus. The Tax-1 protein is known as the transactivator factor of the HTLV-1 virus genome expression (TransActivator of pX region). It is also involved in the destabilization of several molecular mechanisms within the host, leading to cellular transformation. Tax-1 protein displays several functional domains and interacts with a wide range of cellular proteins. In particular, the Tax-1 protein sequence contains, at its carboxy-terminal end, a motif of four amino acids able to interact with PDZ domain (PSD95-DLG1-ZO1) containing proteins. It has been demonstrated that deletion of the PDZ binding motif (PBM) of the Tax-1 protein leads to a decrease of its oncogenic capacity in vitro. Cellular proteins containing PDZ domains are involved in the formation of cellular junctions, synapses and in cellular receptors assembly. Some of PDZ proteins are capable of relaying extracellular signals and participate in the control of proliferation. The human genome codes for at least 150 proteins with PDZ domains. However, the specificity of the oncoprotein Tax-1 to target these proteins remains unknown. In this study, we have mapped The Tax-1 - PDZ interactome using a combination of several methods. We reveal that Tax-1 selectively target a number of PDZ domains-containing proteins potentially involved in HTLV-1 pathogenesis. We validated our approach by focusing on the role of SDCBP and LNX2 proteins in HTLV-1 biology. Our work also demonstrated that the Tax-1-PDZ interactome might represent an attractive therapeutic target for HTLV-1-induced diseases. [less ▲]

As Greg Garrard stresses, “[i]nterpretation and critique of the various inflections of dwelling is a major task for ecocritics interested in a predominantly political, rather than moral or spiritual, project of cultural critique that can take us beyond pastoral and nature writing, from the landscapes of leisure to the uneven terrain of real work” (2012). In this paper, I will examine American literary texts dealing with representations of dwelling or “home” as a refuge from the “tensions” or problems caused by modern civilisation and technology. Starting with Thoreau’s Walden (1854), I will focus on the relationships between such refuges, the natural environment, and socio-political critique. Indeed, Thoreau’s work displays a philosophy on nature and dwelling that has influenced other writers to ponder on the negative effects that modern technologies, capitalism and consumerism have had on the human self and, more largely, on our physical environment. Adopting an ecocritical perspective, I will therefore consider Thoreau’s stay in Walden Pond as well as Edward Abbey’s house trailer (Desert Solitaire, 1968), Christopher McCandless’s “magic bus” as depicted in Jon Krakauer’s Into the Wild (1992) or Ken Ilgunas’s “vandwelling” (Walden on Wheels, 2013) to study the socio-political and environmental concerns raised by dwelling experiences in such peculiar or isolated “homes”. Finally, I will also briefly discuss the Native American perspective through an analysis of Leslie Marmon Silko’s novel Ceremony (1977) as an example of the Laguna Pueblo’s perception of nature or the “land” as “home”.

Le Programme international pour le suivi des acquis des élèves (PISA) a pour objectif de produire des indicateurs sur les habiletés et les connaissances qui contribuent au succès des élèves, des écoles, des systèmes éducatifs et des environnements d’apprentissage (CMEC, 2015, p. 7). Depuis 2000, l’enquête du PISA est planifiée à tous les trois ans pour les élèves de 15 ans en ciblant spécifiquement les matières suivantes : la compréhension de l’écrit, la culture mathématique et la culture scientifique. Dans le cadre de la dernière passation, les résultats des Canadiens à cette enquête ont été salués dans l’ensemble du pays : les élèves se classent dans le groupe des pays les plus performants pour toutes les disciplines couvertes. Par contre, le taux de participation des écoles ainsi que les taux d’exclusions des élèves au regard de divers handicaps, qui pourraient éventuellement avoir un impact sur les résultats et le classement international, ont été critiqués à travers le pays. Cette présentation a comme objectif d’étudier le rendement des élèves canadiens au programme international des acquis scolaires (PISA) entre 2000 à 2015 en fonction de différentes caractéristiques relatives à la participation des écoles et au taux d’exclusion des élèves présentant certains handicaps. Des modèles de régression linéaire à niveaux multiples sont utilisés à cette fin. [less ▲]
