La mise en œuvre de la sélection génomique basée sur une simple prise de sang constitue une étape majeure dans l’histoire de l’élevage bovin. C’est une véritable révolution qui s’accompagne de nombreux changements, qu’il s’agisse de la multiplicité des informations liées aux nouveaux outils, de la rapidité de leur renouvellement, de l’élargissement de l’offre génétique.Pour comprendre comment les outils génomiques s’imposent dans les pratiques de sélection et avec quelles implications, nous menons une recherche sur le terrain de la race Montbéliarde en Franche-Comté auprès d’éleveurs, d’inséminateurs et de techniciens-cadres des entreprises de sélection.

As flexible career paths become more common in European labour markets, how to combine the flexibility required by non-standard work with new patterns of security is the focus of political debate. Some European Union (EU) countries have launched radical labour market reforms, while in others such reforms remain limited. This paves the way for bottom-up solutions developed by private and non-profit labour market intermediaries in order to support the job transitions of non-standard workers. We map these initiatives through a multidimensional grid and explore the extent to which they contribute to renewed regulation of modern labour markets. We outline two ideal-typical approaches. The first extends internal labour markets to triangular employment relationships by considering workers as ‘quasi-employees’. The second involves more disruptive solutions by treating non-standard workers as ‘quasi-self-employed’. [less ▲]

The present study focuses on the whys and wherefores of the online-oriented pedagogical redesign of a course in mathematics in the context of the Feedback First-Year Project (FFYP) implemented in an architecture programme at the University of Liège (Belgium). Lead in order to support the experience and learning of freshmen within the institution, FFYP aimed to involve a group of professors from the same Faculty in a reflection about their current teaching and assessment practice and possible improvements. The teachers were especially acquainted with feedback-related issues through structured moments of personal coaching and collegial meetings, fed by the provision of theoretical resources, among which Nicol’s “12 Principles of good formative assessment and feedback”(2009). This communication reports and analyses three significant devices set up by one of the teachers for students in her course within FFYP. The first one is a 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, each of these features are completed with specific feedbacks to the students. At the end of the process, students were asked about their perceptions on this system. The presentation concludes with the processing of those date and the mention of factors that made the success of the scheme. [less ▲]

-Key message Diachronic photogrammetric canopy height models can be used to quantify at a fine scale changes in dominant height and wood volume following storms. The regular renewal of aerial surveys makes this approach appealing for monitoring forest changes. -Context The increasing availability of aerial photographs and the development of dense matching algorithms open up new possibilities to assess the effects of storm events on forest canopies. -Aims The objective of this research is to assess the potential of diachronic canopy height models derived from photogrammetric point clouds (PCHM) to quantify changes in dominant height and wood volume of a broadleaved forest following a major storm. -Methods PCHMs derived from aerial photographs acquired before and after a storm event were calibrated using 25 field plots to estimate dominant height and volume using various modeling approaches. The calibrated models were combined with a reference damage maps to estimate both the withinstand damage variability, and the amount of volume impacted. -Results Dominant height was predicted with a root mean squared error (RMSE) of 4%, and volume with RMSEs ranging from 24 to 32% according to the type of model. The volume impacted by storm was in the range of 42–76%. Overall, the maps of dominant height changes provided more details about within-stand damage variability than conventional photointerpretation do. -Conclusion The study suggests a promising potential for exploiting PCHM in pursuit of a rapid localization and quantification of wind-throw damages, given an adapted sampling design to calibrate models.

Développé par Christophe Lejeune, Cassandre est un logiciel d'analyse qualitative (libre, open source et gratuit). À la différence des logiciels envisageant l'analyse comme une étape séparée de la recherche, la nouvelle version de Cassandre (3.0) accompagne le chercheur de ses premiers questionnements jusqu'à la publication des résultats. Plutôt que de rassembler un "corpus" et de retarder le saut interprétatif, l'analyse débute dès le premier jour de la recherche, avant même le premier contact avec le terrain. Le développement de Cassandre prolonge les enseignements méthodologiques du Manuel d'analyse qualitative (De Boeck, 2014), rédigé par Chr. Lejeune. Résolument qualitative, son approche invite à Analyser sans compter ni classer. La tenue du journal de bord réside au cœur du logiciel. En écrivant, le chercheur formule son questionnement, prépare le terrain, met en forme son matériau empirique, y repère les dimensions porteuses, les articule et les conceptualise. Encourager la collaboration et le débat scientifique. En tant que plateforme collaborative, Cassandre facilite le travail en équipe. Ces fonctionnalités profitent également au chercheur isolé. Cassandre lui permet en effet partager des résultats intermédiaires avec des informateurs, un client, des collègues, un comité d'accompagnement ou un directeur de thèse. Leurs commentaires l'encouragent à affiner son analyse au fil de l'eau. Pour une recherche qualitative rigoureuse & créative ! Favorisant une organisation souple du travail scientifique, le logiciel Cassandre participe à l'émergence d'idées neuves. Chaque étape du processus de recherche est documentée dans le journal de bord. L'ancrage et la validation de la démarche du chercheur sont de la sorte assurés : "En documentant le maillage entre le terrain et la théorie, les traces en question assurent que la théorie s'appuie toujours sur des éléments attestés".

A scale model of the double side weir spillway of Aubusson d’Auvergne dam has been built and operated with a 1:20 scale factor and Froude similitude. The model enabled designing and optimizing, in concertation with the Client, a modified geometry of the structures meeting updated discharge capacity requirements. The modified geometry includes a fish ladder within the limits of the secondary channel. It implies modifications of the secondary channel cross section and longitudinal profile, the building of a side wall along the right bank and of a downstream ski jump with a deflector as well as a partial lowering of the side wall between the main and the secondary channels on its downstream part in order to optimize the use of the existing ski jump. From the designer point of view, the use of a hydraulic model enables, for a structure with a complex and non-conventional geometry, to clearly identify its hydraulic limitations and the solutions to be analyzed in order to mitigate them and thus fulfill the new design criteria. It would probably not have been possible to define the proposed solution without the use of a physical model as it is closely related to the hydraulic specificities of the studied structure. Thus, even in the case of small dams, hydraulic experimental modeling may improve the design, making it safer, better optimized and then decrease the project overall costs. [less ▲]

In order to study the variation of the hydraulic characteristics of ogee-crested weirs for upstream heads higher than the design head, several profiles have been tested on an experimental facility specifically designed and instrumented. These profiles have been defined regarding the real profiles of spillways of dams operated by EDF as well as the most used geometry of the literature. The experimental tests have been supplemented by numerical modeling, whose results were found to be very similar. The analysis shows that the discharge coefficient increases with the upstream head until head ratios around 5.5. This evolution follows very well the power equations from the literature. For higher head ratios, the discharge coefficient abruptly decreases from a value around 0.6 to a value around 0.55. This decrease corresponds to the apparition between the main flow and the weir of a low velocity area (the lower nappe does no more correspond to the weir profile). The analysis also shows a significant reduction of the discharge coefficient (around 10%) if the upstream quadrant design head is higher than 2 times the design head of the downstream quadrant. On the contrary, no modification of the discharge coefficient is measured if the upstream quadrant design head is smaller than the downstream quadrant one. [less ▲]

Current statistics show that the attrition rate among PhD candidates is high (i.e. from 30% to 40% depending on the discipline and the country). This high-attrition rate has an impact on both economic (e.g. negative impact on the return-on investment in doctoral education) and human levels (e.g. negative consequences on candidates’ self-esteem and well-being). Therefore, it seems important to better understand and to prevent the attrition among PhD candidates. Based on the needs–supplies fit theory, the present research focused on the perception of a fit between several PhD candidates’ work-related needs in terms of employment quality and the characteristics of their job to explain their intention to quit their PhD thesis process. This study was based on 160 Belgian PhD candidates, viewed as traditional workers in the Belgian doctoral system, who were still in their thesis process. Data were collected in one Belgian university. Globally, results shown that only the fit perception between the needs for fairness/recognition from the supervisor and the current job situation was significantly associated with lower intention to quit. Thus, we encourage Universities to develop and boost fairness and recognition from thesis supervisors through notably specific training programmes including supportive and justice-based practices.

For most fires occurring in buildings with a concrete structural frame, the structural elements do not collapse during fire exposure, and further use of the building after fire may be possible. Fire can nevertheless result in a permanent loss of strength and thus a post-fire evaluation of the residual load bearing capacity has to be made to inform decisions on continued use and the need for structural repairs. This evaluation is however particularly difficult due to the many uncertainties associated with both the fire exposure and the characteristics of the structural elements. These uncertainties cannot be neglected when determining the residual capacity since adequate safety is a major societal concern as indicated by the predominance of safety in current design standards and guidance documents. In this paper a comprehensive methodology is presented for the assessment of the residual capacity of concrete structures after exposure to fire. The methodology is introduced through application to a real-life case study of an apartment fire with a focus on the end-span of the affected continuous concrete slab. It results in a reliability-based evaluation of the maximum allowable characteristic value for the imposed load on the slab. The presented methodology is useful to make informed decision about continued use of structures after a fire event. [less ▲]

A coordinated supervisory control scheme for future multi-terminal High-Voltage Direct-Current (HVDC) grids is proposed. The purpose is to supervise the grid and take appropriate actions to ensure power balance and prevent or remove voltage or current limit violations. First, using DC current and voltage measurements, the power references of the various Voltage Sources Converters (VSC) are updated according to participation factors. Next, the setpoints of the converters are smoothly adjusted to track those power references, while avoiding or correcting limit violations. The latter function resorts to Model Predictive Control and a sensitivity model of the system. The efficiency of the proposed scheme has been tested through dynamic simulations of a five-terminal HVDC grid interconnecting two asynchronous AC areas and a wind farm. [less ▲]

This paper offers a reconstruction of Külpe’s theory of cognitive attitudes from the perspective of contemporary debates about cognitive phenomenology. I argue that Külpe’s view constrasts with analytic mainstream approaches to the same phenomena in at least two respects. First, Külpe claims, cognitive experiences are best described in terms of occurrent cognitive acts or attitudes toward sensory, imagistic or intellectual contents. Second, occurrent cognitive attitudes are intransitively conscious in the sense that they are experienced by, or phenomenally manifest to, the subject. I call the combination of those two claims the conscious cognitive attitudes theory. I suggest that, despite some difficulties, this theory offers a worth-considering alternative to contentual and/or nonphenomenological theories of cognitive phenomena. [less ▲]

Introduction : Vegetative state/unresponsive wakefulness syndrome (VS/UWS) is defined by the presence of eye-opening and the absence of awareness and voluntary movement [1]. VS/UWS patients classically receive hydration and nutrition through an enteral feeding tube. Objective - Methods : We retrospectively reviewed the clinical information of 65 VS/UWS patients (aged 45±12; range 16-85 years) evaluated at the CHU hospital of liege searching for mention of oral feeding. VS/UWS diagnosis was made after repeated behavioral assessments using the standardized coma recovery scale–revised (CRS-R, [2]) in association with complementary evaluations using neuroimaging techniques. Results : Of the 65 VS/UWS patients, two could resume oral feeding (3%). One could achieve full oral feeding and the other had oral feeding in addition to gastrostomy feeding. Neuroimaging evaluations showed in both patients a massive decrease in the spontaneous brain activity and its functional connectivity (using functional magnetic resonance imaging), bilateral cerebral cortex hypometabolism and preserved metabolism in the brainstem and cerebellum (using positron emission tomography). Discussion – Conclusion – Clinical message : oral feeding is rare in VS/UWS patients (3% in our cohort). Based on neuroimaging results, this behaviour does not seem to be incompatible with the diagnosis of VS/UWS but the neuromecanistic root, which allows this behavior, still needs to be elucidate. This study also emphasizes the importance of assess and manage deglutition in patients with altered state of consciousness regardless of their level of consciousness. Tactile oro-facial stimulation, manual therapy, taste stimulation and therapeutic feeding can be another “gateway” to interact with these patients and improve their quality of life. [less ▲]
