Les architectes ont toujours eu recours à de multiples représentations pour générer, faire évoluer puis communiquer leurs concepts architecturaux (tant aux pairs qu’aux usagers, ou encore aux décideurs). Cet article envisage comment la représentation externe impacte la perception « naïve » d’une intention architecturale, les « non experts » assumant des rôles de plus fondamentaux au sein de certains mécanismes décisionnels. Comment l’image, en pleine mutation depuis l’ère du numérique, façonne-t-elle la perception des facteurs clés (ou « attributs ») d’une intention architecturale ? L’article résume les principaux résultats d’une enquête menée en ligne via l’interface « Amazon Mechanical Turk » et générant 790 échelles d’évaluation de 6 avant-projets architecturaux. Les résultats abordent l’analyse des données en regard des différentes attributs; en regard des trois types de représentation choisies et en regard enfin des inconsistances dont font preuve les architectes eux-mêmes, étant donné l’évaluation de leurs propres projets et représentations. Ils révèlent que les attributs ne sont pas équitablement propices à un transfert d’intention exclusivement graphique et que les formes plus abstraites de représentations constituent, dans certains contextes, le moyen le plus efficace pour le transfert fidèle d’une intention architecturale.

“Governing by numbers” is a trend on the increase in public action. Numbers tend to pervade the politico-administrative space without questioning neither the quantification processes which produce them nor the conditions of their utilization in government. And yet the use of numbers and data in political arguments contribute to transform the terms of the debate: politics can transform data and indicators, but one should not neglect how numbers affect policymaking. This article proposes as case study the analysis of some recent transformations of public research funding mechanism in universities in French speaking Belgium. It questions the systemic effects of the use of performance indicators in public management in this sector and it proposes some starting points for a discussion of their impact on the quality of the political debate.

The present paper gives a global overview on recent developments performed at the University of Liege on structural robustness of buildings for the specific scenario ‘‘loss of a column’’. In particular, a complete analytical method to assess the response of a 2D frame losing statically one of its columns is presented in details. This method is based on the development of alternative load paths in the damaged structure and takes into account the couplings between the different parts of the structure which are differently affected by the column loss. Also, the validation of the developed method through comparison to experimental and numerical evidences is presented. [less ▲]

Par une introduction détaillée et une sélection de neuf textes emblématiques traduits en français, l’enjeu de ce volume est d’introduire le lecteur francophone à l’histoire de la controverse sur le contenu conceptuel de la perception et de lui en proposer une fine compréhension par l’analyse des différents arguments mobilisés dans les deux camps. Simultanément, le volume a pour ambition de tester la longévité de ces arguments et d’interroger la place qui est dévolue à la controverse sur la scène philosophique la plus contemporaine. [less ▲]

Migraine is a highly prevalent and disabling disease. The drugs prescribed for migraine prophylaxis can have intolerable side effects or can be ineffective. Neuromodulation techniques are increasingly used in neurology. Transcutaneous supraorbital nerve stimulation is effective in episodic migraine prevention, whereas vagus nerve stimulation provides interesting results in acute migraine therapy. Transcranial stimulation techniques gave variable, and sometimes contradictory, results. The visual cortex is the target of choice in migraine: studies in migraine prevention and aura acute treatment are encouraging. These noninvasive therapies appear safe with a low rate of side effects. Available studies of invasive occipital nerve stimulation in chronic migraine gave modest results; but invasive occipital nerve stimulation offers a new hope to highly disabled patients who failed to respond to any other treatment. In the future, neuromodulation will probably take an increasing place in migraine treatment, as add-on therapy or alternative to medications, especially because of its attractive safety profile.

Political parties are key political actors in both Quebec and Wallonia. As their foremost ambition is to govern their region, these parties clearly contribute to shaping its identity and image. This chapter aims at exploring how political parties in Quebec and in Wallonia speak about their region by focusing on an analysis of their electoral manifestos for the period 1994–2014. Using a quantitative and qualitative approach combining insights from lexicometry, cognitive linguistics and political science, the aims of this contribution are (i) to unravel how the parties perceive their region and its future development, (ii) to identify relevant evolutions in their perception of their respective region, and (iii) to assess to what extent parallels can be drawn between the two regions.

The glycosyltransferases of family 51 (GT51) catalyze the polymerization of lipid II to form linear glycan chains, which, after cross linking by the transpeptidases, form the net-like peptidoglycan macromolecule. The essential function of the GT makes it an attractive antimicrobial target; therefore a better understanding of its function and its mechanism of interaction with substrates could help in the design and the development of new antibiotics. In this work, we have used a surface plasmon resonance Biacore((R)) biosensor, based on an amine derivative of moenomycin A immobilized on a sensor chip surface, to investigate the mechanism of binding of substrate analogous inhibitors to the GT. Addition of increasing concentrations of moenomycin A to the Staphylococcus aureus MtgA led to reduced binding of the protein to the sensor chip as expected. Remarkably, in the presence of low concentrations of the most active disaccharide inhibitors, binding of MtgA to immobilized moenomycin A was found to increase; in contrast competition with moenomycin A occurred only at high concentrations. This finding suggests that at low concentrations, the lipid II analogs bind to the acceptor site and induce a cooperative binding of moenomycin A to the donor site. Our results constitute the first indication of the existence of a positive cooperativity between the acceptor and the donor sites of peptidoglycan GTs. In addition, our study indicates that a modification of two residues (L119N and F120S) within the hydrophobic region of MtgA can yield monodisperse forms of the protein with apparently no change in its secondary structure content, but this is at the expense of the enzyme function.

This paper attempts to address the challenges of how to invest in Synthetic Biology firms, most of which are relatively new start-ups and unprofitable. Valuing an early-stage firm with only a brief operating history, little or no operating profit (or even revenue), and an immature and untested business model, could be a formidable challenge. We propose a limited number of quantitative, and a larger number of qualitative criteria. An investor may consider these when faced with analyzing a new untried business, but one he/she believes has considerable potential for success in the future. [less ▲]

BACKGROUND: Elevated resting heart rate is associated with worse outcomes in chronic heart failure (HF) but little is known about its prognostic impact in acute setting. The main aim of the present study was to examine the relationship between resting heart rate obtained 24-36h after admission for acute non-arrhythmic HF and in-hospital mortality. METHODS AND RESULTS: We examined the association of heart rate with in-hospital mortality in a cohort of 712 patients admitted for acute HF. None of the patients had significant arrhythmias, required invasive ventilation, or presented with acute coronary syndrome or primary valvular disease. Forty patients (5.6%) died during the hospital stay. Those patients were significantly older (78+/-9 vs. 72+/-12years; p=0.0021), had higher heart rate (92+/-22 vs. 78+/-18bpm; p<0.0001), NT pro-BNP (p=0.0005), creatinine (p=0.023), were often diabetics (p=0.026) and had lower systolic and diastolic blood pressures (p<0.05). There was a significant graded relationship between the increase in mortality rate and tertile of heart rate (p<0.01). With multivariable analysis, age (p=0.037), heart rate (p<0.0001), diastolic blood pressure (p<0.001), prior ischemic heart disease (p=0.02) and creatinine (p=0.019) emerged as independent predictors of in-hospital mortality. After adjusting for predictors of poor prognosis, patients in the highest heart rate tertile had worst outcomes when compared with those in the lowest heart rate group (p=0.007). CONCLUSIONS: Higher heart rate 24-36h after admission for acute non-arrhythmic HF is associated with increased risk of in-hospital mortality. Early targeting of elevated heart rate might represent a complementary therapeutic challenge. [less ▲]

Pulmonary hypertension (PH) is a classic pathophysiological consequence of left-sided valvular heart disease (VHD). However, as opposed to other forms of PH, there are relatively few published data on the prevalence, impact on outcome, and management of PH with VHD. The objective of this paper is to present a systematic review of PH in patients with VHD. PH is found in 15% to 60% of patients with VHD and is more frequent among symptomatic patients. PH is associated with higher risk of cardiac events under conservative management, during valve replacement or repair procedures, and even following successful corrective procedures. In addition to its usefulness in assessing the presence and severity of VHD, Doppler echocardiography is a key tool in diagnosis of PH and assessment of its repercussion on right ventricular function. Assessment of pulmonary arterial pressure during exercise stress echocardiography may provide additional prognostic information beyond resting evaluation. Cardiac magnetic resonance is also useful for assessing right ventricular geometry and function, which provide additional prognostic information in patients with VHD and PH. [less ▲]
