Gene transfection with polymeric carrier remains a challenge, particularly high transfection levels combined with low toxicity are hard to achieve. We herein revisit polyvinylamines, an old and neglected family of cationic polymers. They can be readily obtained by controlled hydrolysis of polyvinylamides prepared through (controlled) radical polymerization. A series of tailor-made and well-defined polyvinylamines bearing primary amino groups, and poly(N- methylvinylamine) bearing secondary amines, were evaluated for the transfection of cells with pDNA as a function of their molar mass, molar mass distribution and degree of deacetylation. Unexpected high transfection levels, in combination with low cytotoxicity were recorded for both series. Surprisingly, a great impact of the molar mass was observed for the primary amine polyvinylamine series, whereas the results were mostly independent on molar mass or dispersity for the polymer bearing secondary amine. It was further established that a certain percentage of acetamide groups increased the transfection level, while maintaining low cytotoxicity. These results highlight for the first time the real potential of polyvinylamines as gene carriers, and make these polymers very attractive for further development in gene therapy. [less ▲]

Created at the University of Liège (Belgium) in 2006, the CDS - IFRES offers to all the new faculties and teaching assistants the opportunity to participate to a pedagogical training program dealing with a wide range of themes exclusively related to the enhancement of teaching activities for first-year students. More than 1400 staffs have already attended to those sessions in which dissemination of good practices in the first-year course takes a large part. Leading a reflective analysis of the process of this program and its outcomes through various data, this communication offers great insights for conceptors of faculty training programs. [less ▲]

L’empire byzantin se présente d’une certaine façon comme la traduction en grec de l’Empire romain. Fondée par Constantin en 324, mais achevée au VIe s., au temps de Justinien, Constantinople tâcha de s’imposer comme nouvelle Rome en terre grecque, puis, après la chute de l’Empire romain d’Occident, comme la seule version autorisée de l’Imperium Romanum. Rome était une ville bilingue. Constantinople se devait de l’être aussi. N’en déplaise à ceux qui avaient favorisé cette œuvre de translation, Constantinople n’était toutefois qu’une copie, une « belle infidèle », par rapport au prototype, qui reste unique. Il n’empêche que la romanité de Byzance est une évidence aux yeux de tous. Je tenterai de mesurer le degré de pénétration de la culture littéraire de langue latine à Constantinople à l’époque de l’empereur Justinien.

Cette recherche traite de la dynamique de subjectivation portée par la figure du sujet-entrepreneur, évoluant en dehors du sérail étatique au Cameroun. Son expérience biographique laisse percevoir un modèle d’engagement dit entrepreneurial qui l’inscrit au cœur de l’histoire sociale et politique en cours. Le récit de vie laisse percevoir un souci pressant de réalisation de soi qui le pousse à relativiser les supports institutionnels classiques, et non moins contraignantes, de socialisation. Durant son parcours, la démarcation de ces dernières conduit à la répugnance d’une carrière administrative « tranquille » et est assortie d’un discours critique sur la politique du ventre. Cette démarcation serait en outre au cœur d’une rupture biographique qui l’astreint à s’engager, de manière individualisée, à la promotion d’une société utopique à partir de son champ professionnel. Son engagement présente une variété de typologies d’action liées à la sensibilité et aux convictions personnelles, à l’expérience acquise au cours de la trajectoire biographique, et à l’orientation donnée à l’activité. Cette variété d’actions trouve un lieu commun dans le besoin de subvertir l’ordre sociopolitique dominant en vue de promouvoir l’avènement d’une cité alternative. En cela, les logiques d’action du sujet-entrepreneur s’inscrivent dans une dynamique historique de subjectivation qui informe les processus d’individualisation. [less ▲]

During the middle Palaeolithic, the northern France was only occupied by Neanderthals groups. However, successions of glacial and interglacial cycles explain a complex and discontinuous settlement, raising complication in the study of its dynamics at a regional scale. Therefore, some aspects of Neanderthals behaviour are still mischaracterize: in most cases, the function of the site and its territorial management over the northern France have to be specified. The spatial analysis of open air sites from northern France will help us to answer those questions. However, for Middle Palaeolithic sites, we can't see systematically on the field the spatial organisation directly, we sometimes need modelization. Therefore, we started to build a spatial analysis protocol adapted to this site and applied to such sites. The sites of Caours (Somme, France) and Beauvais (Oise, France) are two open air sites that are exceptionally well preserved and displaying a large amount of faunal and lithic rests. Both are perfect candidate to apply and test the new protocol. First results proved that for each site the existence of a spatial organisation as remains concentration zones. Then, we characterize this areas – number, distribution. Finally, we were able to associate them to human activity areas like hearths, butchery or knapping areas. [less ▲]

The notion of Landscape Observatory (ELC 2000), in the work of LabVTP at the Faculty of Architecture in the University of Liège (Wallonia-BE), has been linked with the concept of Landscape Laboratory (R. Gustavsson) in order to enhance and underline perceptive, experiential and active dimensions of sites, responding to the Universities’ missions required by the ELC: education and sensitization. Lab Pay(s)age, as a new typology of landscape laboratory, has developed methodological tools for landscape research, based on a multi-scale and diachronic reading of the territory, where natural and artificial traces are the complementary elements to be reinterpreted and relaunched in new participative scenarios. The Meuse valley, reshaped by deep transformations, is the main topic for researches, concerning specific morphological, typological and social characters. All along the river, the scars of industries mark the territory as a land in search of new cycle of life1. The regeneration of abandoned industrial sites, as a practice of territorial recycle, is part of sustainability policies in urban planning, based on the enhancement of local resources. The Observatory Lab Pay(s)age, is intended as a structure for site-specific study and continuous fieldwork, concerning both the evolutionary processes of natural structures and the involution of built environment. Starting from these materials, many different regeneration methodologies and temporalities have been imagined. Following the logic promoted by the ELC, the work has started by monitoring some specific areas and by contacting different local representatives with the aim of collecting data and experiences to construct a shared knowledge of the places. Then the project has become an on-going tool including all phases in the regeneration process: observation, analysis, interpretation and re-launch of new hypothesis are fundamental elements to increase the public knowledge about the cultural factors characterizing the landscape discipline. Thus, the notion of « observatory » is a strategic device, monitoring the evolution of places in time through actions of dialogue and awareness raising, in order to get citizens re-acquire a consciousness of their territory. The collected qualitative data, describe the peculiar features of the sites, based on the local actors experience and knowledge. These elements are the basis for new scenarios, used as progressive steps leading the recovery process. For this reason, the « observatory » is also a « laboratory », as the experimental projects accompany the transformation of the places through intermediate phases. Understanding and accepting mutability as a character of landscape is a preliminary step towards a co-action, where the project accords with natural dynamics. Lab Pay(s)age, according to the ELC principles, is using the earliest local answers as re-launch factors for consecutive projects, taking into account the territorial temporalities as priority in transformation process. The presentation concerns the ongoing projects and obtained reactions, such as the earliest re-naturalization programs, some selected sites for monitoring activities and Phd researches on new regeneration methods using vegetation as an active element in reclamation of industrial sites. 1 Occhiuto, R. 2016.

This presentation focuses on multiple-choice items without any correction or control for guessing. Most often, item responses are recoded as binary outcomes so that dichotomous logistic item response models (such as the 2PL or 3PL models) can be used to estimate ability levels. This is however at the cost of loosing information from collapsing all distractors into a single FALSE category. Polytomous IRT models could be considered to overcome that drawback but none of the classical models are suitable to incorporate guessing into account. The purpose of this talk is to introduce a modification to the graded response model (Samejima, 1969) that can take guessing into account. The modification consists in introducing lower and upper asymptotes to the cumulative probability curves. After a brief theoretical and technical description, practical implementation using the R package mirt (Chalmers, 2012) is discussed. Primary results from a simulation study are eventually presented and compared to traditional IRT scoring methods for scoring multiple-choice items. [less ▲]
