La confrontation de la version anonyme en vers de Barlaam et Josaphat avec sa mise en prose, produite au XIIIe siècle, offre un point de vue privilégié sur la langue littéraire en prose, à l’aube de son épanouissement. Parallèlement au retranchement d’épisodes entiers, le remanieur s’applique à conserver une étroite proximité avec la lettre de son modèle francien, et semble tendre vers un compromis entre fidélité au texte-source et intelligibilité du texte-cible. Ainsi, à côté de l’importation massive du matériau lexical et des structures syntaxiques du texte versifié, toutes ses interventions sont observables. Notre communication s’est focalisée sur un échantillon de neuf substitutions lexicales dont nous avons mesuré la fréquence et dont il s’agissait d’identifier les implications. En tant que témoins de l’actualisation linguistique du texte-source, ces variations (diachroniques et/ou diaphasiques) permettent d’améliorer la connaissance du vocabulaire de la mise en prose de Barlaam et Josaphat et de cerner avec plus de précision la sensibilité du remanieur à l’égard du lexique de sa source.

The aim of this study was to investigate the impact of test format on recollection and familiarity in normal aging and in MCI. Seventy young participants, 65 younger-old, 53 older-old, and 13 MCIs were presented with forced-choice and yes/no visual recognition memory tasks with the Remember/Know/Guess paradigm. The young people had better recognition performance than younger-old, who performed better than older-old and MCIs. Recollection and familiarity declined progressively in healthy aging. In MCI, recollection was more affected than familiarity, but patients demonstrated a more liberal use of familiarity. Finally, test format did not influence strongly the results. Young people used recollection more often in the forced-choice task compared to the yes/no task. [less ▲]

La politique du bilinguisme officiel s’est imposée au Cameroun pour des raisons d’unité nationale suite à une double colonisation franco-britannique. En milieu scolaire, le bilinguisme renvoie généralement à l’enseignement du français en tant que deuxième langue officielle aux Anglophones et, à l’enseignement de l’anglais en tant que deuxième langue officielle aux Francophones. Néanmoins, les élèves anglophones éprouvent d’énormes difficultés d’intégration à la fin des études secondaires. Quels sont donc les objectifs de l’enseignement du français aux élèves anglophones ? Quelle est l’approche méthodologique mise en œuvre pour atteindre ces objectifs ? Et enfin, comment allier objectifs scolaires du bilinguisme et méthodologie du FLE pour préparer les élèves anglophones à la vie après le secondaire ? [less ▲]

Simulation studies are often used to compare methods to detect differential item functioning (DIF). However, comparing the performance of such methods can become complicated when the identification of DIF items relies on statistics based on pre-defined significance level or on pre-established cutoff values. DIF methods based on conceptually different approaches may therefore become incomparable in terms of summary DIF statistics such as false alarm rate or hit rate. The purpose of this talk is to overcome this analytic issue by introducing receiver operating characteristic (ROC) curves in this context. ROC curves allow for global comparison of methods’ performances by computing pairs of (false alarm, hit) rates and representing them on a common scatter plot. Several summary ROC statistics can be considered for further analysis. The application of the ROC curve methodology, together with its limitation and possible extensions, is illustrated by a simple simulation study that compares three score-based DIF methods (Mantel-Haenszel, standardization and Delta plot).

Conformity to a known distribution and sensitivity to response aberrance are desirable properties of person-fit statistics. This simulation study examined the joint and independent effects of two adjustments to the standardized log-likelihood statistic (lz): (1) correction of the negatively skewed distribution of lz (Snijders, 2001), and (2) improving the sensitivity of the statistic by employing more accurate estimates of item response probability using symmetric functions (Dimitrov and Smith, 2006). Data were simulated using three test lengths (10, 20, 30 items). Data containing misfitting response patterns were simulated using three aberrant response patterns (cheating, guessing, and inattentiveness), and three levels of aberrance (i.e., proportion of item responses affected by misfit; 10%, 30% and 50%). Data containing no simulated misfitting response patterns were also generated for each test length. Non-misfitting responses were generated using the dichotomous Rasch measurement model. For each combination of independent variables, a dataset was generated consisting of 5,000 simulees. Four fit statistics were compared: lz, lz* (Snijders adjustment), lzSYM (Dimitrov and Smith adjustment), and lzSYM* (both adjustments). Mean Type I error rates were ≤ 0.1 across all conditions. The lz* statistic produced the best control of Type I error, which was often below the nominal Type I error rate, whereas the empirical Type I error rate for the unadjusted lz statistic most closely approximated the nominal rate. In contrast, lzSYM and lzSYM* yielded empirical Type I error rates larger than the nominal rate, with the discrepancy being particularly pronounced as the length of the test decreased. As might be expected, power to detect misfitting response patterns increased with test length and with the percentage of misfitting response patterns in the sample. Both lzSYM and lzSYM* evidenced improved power in detecting misfitting response patterns compared to lz and lz*, particularly for guessing response patterns and/or on shorter (i.e., 10 item) tests.

This paper explores the transition of informal temporary camps on the French border to a sustainable state, and discusses how local policy decisions and non-state actors worked together for the implementation of a semi-permanent exclusion system based on the refugee crisis. I observe this issue as a result of a securitization process. The securitization apparatus (speech acts and policies), produced the immobility of a group. In the other hand actors will emerge to produce mobility. When a situation is defined as a crisis, atypical actions can be employed to protect the «political community». I started from the assumption that dialectic relation between securitization and camps actors had a high impact on the projects of refugees, and so long in their mobility. This is a question of integration policies at the local level. I aim to highlight the local level relevance, where the integration is primarily implemented, and therefore local and regional context should matter as much as the national model for integration (Martiniello, 2013). In Calais, due to the lack of immigrants policies, civilians associations started to react and build informal camps, but due to recent "crisis" the Stat concentrated all refugees in a single camp, 6 kilometers from the city center, called bidonville.

How and through which practices do Ageing Migrant Domestic Workers negotiate their access to social protection across borders? How are these negotiations influenced both by their intersecting gender, race, class, generational standpoints and their transnational family relations? This contribution deals with these questions and focuses on the case of Peruvian and Colombian Ageing Migrant Domestic Workers in the city of Brussels. Such migrants share a paradoxical positioning as they contribute productively and reproductively to the development of their receiving and sending societies but experience a lack of formal and informal social protection on both sides. This analysis first maps through a moving ethnography the practices they use to negotiate their access to Social Protection in the areas of: 1- access to labor, 2- social security entitlement and portability, 4- housing and 3- informal symbolic-practical care. Secondly, it theorizes these practices as an assemblage of social protection that’s simultaneously made out of transnational interpersonal relationships and formal support systems. Thirdly, building from the work of Amelina et al, (2012) Transnational and Intersectional lens are used to analyze how the effectiveness of such assemblage is simultaneously affected by these actor’s gender, race, class and generational positioning within the global reproduction of labor as well as by their transnational family relations. Concluding, it’s argued such assemblage of protection increases ageing migrants’ life chances but reproduces and produces social- inequalities at the local, transnational and global level. This contribution provides a glance at how transnational needs for social protection are negotiated across borders. Furthermore, it’s relevant in a context of increasing human mobility where inequalities in access to social protection emerge as a public transnational social question that is relevant both for academics and policy makers.

This work focuses on the city of Huamachuco, a town 3200 meters above sea level in Northern Peru. The main aim of this study is to share and disseminate technological knowledge on architecture, building technology and lifestyle of Huamachuco inhabitants. The paper objective is to (1) highlight the concept of architectural quality in Huamachuco, (2) compare the living environment of existing traditional dwellings in comparison with newly constructed concrete dwellings, and to (3) identify the reasons for neglecting ecological construction technologies and materials in the new built environment. The research methodology went through different phases that range from qualitative data collection and quantitative measuring, to data analysis and findings reporting. Firstly, a typological study was conducted visiting 110 houses. The typological study enabled us to describe and understand the housing typologies and classify those under four major typologies according to their construction techniques: 1) adobe, 2) rammed earth, 3) concrete and 4) mixed technique. Secondly, detailed field studies were conducted for representative houses representing the four categories. Finally, 10 houses have been thoroughly audited for using measuring equipment to collect data related to temperature, relative humidity, carbon dioxide concentration, lighting intensity, and envelope thermography.

This paper describes a novel methodology for conducting stable hybrid fire testing (HTF). During hybrid fire testing, only a part of the structure is tested in a furnace while the reminded structure is calculated separately, here by means of a predetermined matrix. Equilibrium and compatibility at the interface between the tested “physical substructure” and the “numerical substructure” is maintained throughout the test using a dedicated algorithm. The procedures developed so far are sensitive to the stiffness ratio between the physical and the numerical substructure and therefore they can be applied only in some cases. In fire field, the stiffness of the heated physical substructure may change dramatically and the resulting change in stiffness ratio can lead to instability during the test. To overcome this drawback, a methodology independent of the stiffness ratio has been developed, inspired from the Finite Element Tearing and Interconnecting (FETI) method, which has been originally developed for substructuring in numerical analyses. The novel methodology has been successfully applied to a hybrid fire test in a purely numerical environment, i.e. the physical substructure was also modelled numerically. It is shown that stability does not depend on the stiffness ratio and that equilibrium and compatibility can be consistently maintained at the interface during the fire. Finally, the ongoing experimental program aimed at employing and experimentally validating this methodology is described. [less ▲]

In this paper, we review issues related to the existing hieroglyphic sign-lists, focusing especially on the problematic aspects of the 'Manuel de Codage' (1988) and of the so-called 'Hieroglyphica' (2000) for font-designers and users alike. We propose and discuss a data model for the Thot Sign-List (TSL, in prep.). This data model shall lead to the implementation of a structured and systematically referenced hieroglyphic repertoire, which should ultimately allow a sound extension of the Egyptian Hieroglyphs in Unicode.

LIÈGE, EARLY 1960S. AS IN OTHER EUROPEAN CITIES, THE REAL ESTATE BOOM HAS JUST BEGUN. AS GOOD MODERNISTS, THE MAYOR AND A BENCH OF PRIVATE DEVELOPERS THOUGHT TO RENOVATE THE HOUSING STOCK BY REPLACING THE OLD URBAN FABRIC WITH A NEW HOUSING TYPE : THE APARTMENT BUILDING. IN A 15-YEARS TIME, MOST OF THE 19TH CENTURY HOUSES ALONG THE QUAYS AND THE BOULEVARDS HAVE BEEN SUBSTITUTED BY 12-STOREY HIGH MODERNIST CONSTRUCTIONS. THIS TRANSFORMATION RADICALLY CHANGED THE SKYLINE AND THE IMAGE OF THE CITY. AFTER 50 YEARS, THESE BUILDINGS HAVE COME TO THE END OF A LIFE CYCLE. WITH THE RISING COST OF ENERGY, THE CHANGE IN SOCIETY AND THE EVOLUTION OF NORMS AND STANDARDS, THESE MODERN ‘ICONS’ ARE BECOMING OUTDATED. THERE IS A GROWING NEED TO RECONSIDER THIS TYPOLOGY AND TO THINK ITS POSSIBLE FUTURE. THE SUMMER SCHOOL WILL EXPLORE HOW ARCHITECTURAL INTERVENTIONS COULD REVIVE THIS IMPORTANT HOUSING STOCK.
