Faire l’histoire de l’édition en Belgique à partir de l’apparition du livre imprimé soulève un certain nombre de problèmes en fait de délimitation du domaine et de construction de l’objet. Les plus évidents touchent aux avatars politiques et linguistiques que les territoires formant l’État belge ont connus du XVe siècle à la fin du XXe siècle. D’autres proviennent du rapport de force très inégal qui s’est établi, à partir de la première moitié du XIXe siècle, entre le système de production du livre en Wallonie et à Bruxelles et l’édition française, avec les effets que ce rapport y exercera durablement en termes d’identité culturelle et de rayonnement, de structures de production et de diffusion, mais aussi de créneaux privilégiés. Ces problèmes et d’autres encore – dont témoigne une historiographie volontiers cantonnée à « l’histoire du livre et de l’imprimerie » – méritent d’être réexaminés dans la perspective de la publication imminente d’une Histoire de l’édition en Belgique profilant, du XVe au XXIe siècle, ses principales lignes de faîte. Histoire de l’édition et de ses pratiques – non du livre et de ses techniques. Histoire de l’édition dans toute son extension et à différents niveaux – non de la seule édition littéraire ou lettrée. Histoire d’un espace des possibles ayant su, dans certains secteurs, tirer force et spécificité de contraintes puissamment subies. [less ▲]

Outlier detection techniques in spatial data should allow to identify two types of outliers: global and local ones. Local outliers typically have non-spatial attributes that strongly differ from those observed on their neighbors. Detecting local outliers requires to be able to work locally, on neighborhoods, in order to take into account the spatial dependence between the statistical units under consideration, even though the outlyingness is usually measured on the non-spatial variables. Many procedures have been outlined in the literature, but their number reduces when one wants to deal with multivariate non-spatial attributes. In this paper, focus is on the multivariate context. A review of existing procedures is done. A new approach, based on a two-step improvement of an existing one, is also designed and compared with the benchmarked methods by means of examples and simulations. [less ▲]

We report on the ground-based FTIR (Fourier Transform InfraRed) tropospheric water vapour isotopologue remote sensing data that have been recently made available via the database of NDACC (Network for the Detection of Atmospheric Composition Change; ftp://ftp.cpc.ncep.noaa.gov/ndacc/MUSICA/) and via doi:10.5281/zenodo.48902. Currently, data are available for 12 globally distributed stations. They have been centrally retrieved and quality filtered in the framework of the MUSICA project (MUlti-platform remote Sensing of Isotopologues for investigating the Cycle of Atmospheric water). We explain particularities of retrieving the water vapour isotopologue state (vertical distribution of H162O, H182O and HD16O) and reveal the need for a new meta-data template for archiving such FTIR isotopologue data. We describe the format of different data components and give recommendations for correct data usage. Data are provided as two data types. The first type is best-suited for tropospheric water vapour distribution studies disregarding different isotopologues (comparison with radiosonde data, analyses of water vapour variability and trends, etc.). The second type is needed for analysing moisture pathways by means of {H2O,delta-D}-pair distributions. [less ▲]

Why ask a person to answer a problem item, when you a priori know they won’t be able to solve it? It is a waste of time and resources, and you won’t gain any new information; this is both inefficient and ineffective. In contrast, computerized adaptive testing (CAT) is based on the principle that more information can be gained when one tailors the test towards the level of the person being tested. Computational and statistical techniques from item response theory (IRT) and decision theory are combined to implement a test that can behave interactively during the test process and adapts towards the level of the person being tested.The implementation of such a CAT relies on an iterative sequential algorithm that searches the pool of available items (a so-called item bank) for the optimal item to administer based on the current estimate of the person’s level (and optional external constraints). The subsequent response on this item provides new information to update the person’s proficiency estimate. This selection-responding-updating process continues until specified stop criteria have been reached. The consequence of such an adaptive test administration is that you get an individualized tailored test that is more efficient and more effective. Because you have less of a mismatch between the level of the test and the level of the test taker, there is a lesser burden for the latter and a higher precision for the former, and this with fewer items than a traditional fixed item-set test format. Furthermore, because it is computerized and sequential, test performance can be continuously monitored and reported directly after test completion. Item response models come into play to ensure comparable scores of these individual tailored tests by putting them on the same measurement scale and to precalibrate,the psychometric parameters of the items that are part of the item bank on which the sequential iterative algorithm operates. The workshop intends to tackle issues encountered during the setup of a computerized adaptive test, starting from the design towards the actual delivery of a CAT. [less ▲]

Introduction Allogeneic hematopoietic stem cell transplantation (alloHSCT) offers potential curative treatment for a wide range of malignant and nonmalignant hematological disorders. However, its success may be limited by post-transplant acute graft-versus-host disease (aGVHD), a systemic syndrome in which donor’s immune cells attack healthy tissues in the immunocompromised host. aGVHD is one of the main causes of morbidity and mortality after alloHSCT. Despite standard GVHD prophylaxis regimens, aGVHD still develops in approximately 40–60% of alloHSCT recipients. Areas covered In this review, after a brief summary of current knowledge on the pathogenesis of aGVHD, the authors review the current combination of a calcineurin inhibitor with an antimetabolite with or without added anti-thymocyte globulin (ATG) and emerging strategies for GVHD prevention. Expert opinion A new understanding of the involvement of cytokines, intracellular signaling pathways, epigenetics and immunoregulatory cells in GVHD pathogenesis will lead to new standards for aGVHD prophylaxis allowing better prevention of severe aGVHD without affecting graft-versus-tumor effects.

Reasons to perform study. To assess lameness in animals, semi-objective scales are used. Video is sometimes used to enable blinding of the clinician. In addition, the assessment of pain is particularly difficult in animals since they cannot report their feelings. The interpretation of the reactions of the animals can be different between observers. A method to quantify pain is the measure of mechanical nociceptive thresholds (MNT), a method called algometry. Since synovitis is often linked to swelling of periarticular tissues and to synovial fluid effusion, palpation of the joint is also a useful test. The objectives of the current study were to assess in sheep whether (1) video assessment of lameness is in agreement with real observation; (2) algometry of the knee is correlated with lameness evaluation; (3) algometry is correlated with identification of swelling by palpation. Material and methods. The population of sheep enrolled in a controlled trial at the Ovine Research Center of UNamur was used for the current study. Results. There was a moderate inter-rater agreement (value of kappa was 0,41) between the experimenter who evaluated the ewes on site and the one who watched the videos. No significant correlation was identified between lameness scores and algometry. A negative correlation (algometry reactive threshold is lower when palpation score is higher) was identified between palpation scores and MNT (P<0.05). Discussion. Video assessment can be used in research to assess lameness. The experience of the observer must be taken into account. Algometry is not entirely valid since an adaptation or learning process seems to develop in sheep. [less ▲]

Interface essentielle entre le joueur et l’univers vidéoludique, l'avatar soulève la question du rapport au corps dans le jeu vidéo. En effet, la fonction d’incarnation permise par l’avatar – et qui est soulignée par l’étymologie même du terme – ajoute à la relation entre le corps et l’esprit du joueur une dimension nouvelle : celle du corps virtuel, qui déploie sa matérialité propre au sein de l’univers fictionnel. Ce corps « autre », dont le joueur prend possession, constitue une des conditions de son « insertion » dans le monde virtuel. Fondée sur une approche communicationnelle et nourri d’un pan de la pensée phénoménologique (à travers, notamment, la Phénoménologie de la perception de Maurice Merleau-Ponty), cette intervention entend questionner la problématique du rapport au corps au sein de l’univers du jeu.

L'approche du jeu vidéo, non sous l’angle de la technique ou de l'étude des joueurs, mais comme un ensemble de pratiques et de phénomènes culturels, donne lieu à un double mouvement : d'une part la reconnaissance d'une culture commune qui fait médiation et d'autre part la création d'écarts de différentes natures entre les acteurs, les discours et les esthétiques : écarts de légitimité entre des pratiques ludiques instituées et d’autres plus périphériques (sur lesquelles se centreront les présentes communications), écarts rhétoriques produits par les joueurs qui se réapproprient les œuvres vidéoludiques pour les détourner, écarts identitaires présents dans les discours des amateurs, qui se définissent par des stratégies de distinction (par rapport aux professionnels, aux artistes, etc.) et écarts posturaux, mobilisés par les différents acteurs de la presse vidéoludique afin de se singulariser – notamment pour permettre une existence économique. Cet ensemble de problématiques seront traitées au sein d’un panel de communications, à travers différentes perspectives disciplinaires : la rhétorique et la sémiotique, la sociologie de la littérature et l’analyse des réseaux, et l’approche communicationnelle inspirée des « cultural studies ».
