Dans le contexte de la globalisation post-Guerre froide, l’affirmation de « nouvelles puissances » et l’avènement concomitant de clubs interétatiques tels que les BRICS (Brésil, Russie, Inde, Chine et Afrique du Sud), dans un système international au demeurant dominé par les États-Unis, alimentent les réflexions contemporaines sur la puissance et sa distribution mondiale. Eu égard au rôle international et aux potentialités conférés par sa dimension géopolitique d’État-continent, le seul développement économique de la Chine en fait aujourd’hui un acteur international incontournable (force), alors même que le syncrétisme de son modèle de développement présenté comme un « socialisme aux caractéristiques chinoises », alliant en ce sens des mécanismes de l’économie de marché à des éléments hérités du marxisme-léninisme, lui confère une certaine forme de vulnérabilité constitutive (faiblesse). Si bien que l’énigme de sa puissance (nature) et l’ambivalence de sa réponse à la domination américaine (exercice) enjoignent au double dépassement théorique. La présente thèse, dans son objectif d’analyser la stratégie de construction de puissance de la Chine sur la scène internationale à travers le cas de sa pénétration en Amérique latine, repose dès lors sur un double postulat théorique : la puissance chinoise se définit comme une entreprise de reconnaissance mondiale toujours en redéfinition et au résultat incertain, qui s’opère dans un monde multipolaire en gestation au sein duquel les puissances émergentes rivalisent avec les États-Unis et l’Union européenne (UE) pour la domination. Mesurer l’influence de la Chine sur la scène mondiale, à travers sa capacité à se faire reconnaître comme un acteur international de référence par les autres puissances émergentes et plus encore par les puissances occidentales, procède dès lors également d’une méthodologie ad hoc : seul l’examen corrélé des pratiques des acteurs, étatiques ou autres, (réalité) et du sens qu’ils confèrent à leurs actions (discours) permet de mesurer pleinement l’impact de la représentation que la Chine a du monde, d’elle-même et de sa place dans ce monde, sur les préférences et comportements des autres acteurs du système international. Dans ce cadre, le raisonnement au cœur de la présente thèse s’appuie sur deux parties ou questions centrales. La première interroge la stratégie de construction de puissance de la Chine sur la scène internationale post-Guerre froide. Elle met au jour le poids de trois enjeux fondamentaux en interne dans la construction de son statut d’acteur mondial incontournable, à savoir le poids de l’identité nationale façonnée par l’histoire et l’idéologie, le poids du régime mû par une quête de légitimité structurelle et le poids des intérêts nationaux guidant nécessairement sa diplomatie. La seconde partie questionne ensuite empiriquement la façon dont la Chine construit sa puissance vis-à-vis de l’Amérique latine, région porteuse d’un projet politico-économique sur lequel influent historiquement les stratégies respectives des États-Unis et de l’UE. Elle met au jour le déploiement par la Chine d’une stratégie nécessairement duale de coopération et d’hégémonie visant à consolider sa puissance sans atrophier son ascension (représentation), à même de séduire les États latino-américains (perception), et par conséquent de concurrencer les stratégies américaine et européenne influant sur le sous-continent (reconnaissance).

In this paper I look at the particular situation of Congolese and Belgian-Congolese citizens in Belgium, the former colonial metropole. From research conducted over ten years within Congolese circles I argue that postcolonial immigrants/citizens have for the last three decades been experiencing a significant social malus. Not only does daily racial discrimination inform and supply it but so also does treatment by the state itself through its various institutions. Looking at some data collected from political, associative and artistic spheres I argue that the Congolese in Belgium have to deal with a postcolonial malus. My research is grounded on a comprehensive anthropology which privileges the actors’ own perspective. I thereby explore the elements, trends or configurations of the post-migratory situation which may be considered inherited from colonialism. Finally, I discuss the reason why despite three decades of “postcolonial activism”, the postcolonial critique is not a live social issue in French-speaking Belgium. [less ▲]

Purpose: Aggregated results of systematic reviews separately show how light used as a treatment and some occupational therapy interventions could have a positive impact on psychobehavioural disorders in older people. Since the beginning of June 2014 the Walloon Government has been financing a project which consists of a non-pharmacological approach that combines light and occupational therapy for a psychogeriatric population with specific symptoms: spatial and temporal disorientations, apathy, depression, agitation, anxiety, confusion and circadian disorder. The objective of this abstract is to expose the assumptions that the combination of two different light devices and one specific occupational therapy program could have an impact on the different symptoms of a psychogeriatric population. Methods: To build our hypothesis, two literature reviews have been achieved. The first one concerning the use of light as therapy gathered 30 studies while the other one about occupational therapy activities collected 35 articles. Results: Despite of a heterogeneity between studies dealing with light and occupational therapy, the combination of these two non-pharmacological interventions might fight the depressive syndrome, reduce the temporal disorientation thanks to a regularity in the period of activity, restore the circadian rhythm and so reduce some troubles that can be linked to them: sleep disorder, risk of fall, apathy, agitation, behavioural and cognitive troubles (attention, concentration). Moreover, one of the two light devices used which can modulate the light intensity according to the rooms might reduce the spatial disorientation if it’s employed as a landmark. Conclusions: Based on literature reviews and our experience into this field it’s seems that a non-pharmacological approach involving light and occupational therapy intervention could have a positive effect on symptoms of psychogeriatric population. In admitting that those effects are becoming true after experimentation and analyses, we can also expect an improvement of the quality of life. [less ▲]

In this article, we study the Public-Private Partnerships (PPP) in the field of employment, in Belgium. These PPPs are established between Public Employment Service (PES) and private operators to create projects for support and training for jobseekers the ultimate goal of which is social and professional reintegration. There are three critical moments in the life of the partnership: getting a partnership agreement with the PES, mobilizing jobseekers to participate in the delivery, and evaluating the outcomes achieved by the operator. The parties affected by these three critical steps are mainly the private operators. To overcome these difficulties, the providers implement informal and "clandestine" strategies to ensure the proper operation of the partnership and especially its performance and sustainability.

Nine neurodegenerative disorders, referred to as polyglutamine diseases and including Huntington’s disease, are associated with the abnormal expansion of a polyglutamine tract inside nine unrelated proteins. This polyQ expansion is thought to be the major determinant in the development of neurotoxicity, triggering protein aggregation into amyloid fibrils. A large body of evidence however suggests that non-polyQ regions modulate the aggregation process triggered by polyQ expansions. The interplay between the polyQ tract and non-polyQ regions is complex and still not fully understood. In order to better understand it, we previously designed and characterized model polyQ proteins made of the beta-lactamase BlaP with 23, 30, 55 and 79Q inserted at position 197 or 216. Our first results had indicated that our model is relevant to study polyQ aggregation since it recapitulates the aggregation properties of polyQ disease-associated proteins: there is a Q-threshold for the spontaneous formation of amyloid fibrils in solution, and above the threshold, the longer the polyQ, the faster the aggregation. Moreover, the structure of BlaP and the position of insertion of the polyQ tract influence their aggregation properties in solution. This work aims to better understand, at the molecular level, (i) the precise role of the polyQ length (23, 30, 55, 61, 67, 73 and 79Q), (ii) the conformation of the host protein (native or unfolded BlaP), (iii) the location of the polyQ tract within BlaP (197 or 216), (iv) the flexibility of the polyQ flanking sequences, and (v) the origin of constraints applied by BlaP to the inserted polyQ tract (at its N- or C-terminal end) on the structural, thermodynamic and aggregation properties of BlaP-polyQ chimeras, using a wide range of biophysical techniques (e.g., spectroscopy methods, quartz crystal microbalance, atomic force microscopy and dynamic light scattering). The effect on the aggregation properties will be determined on the spontaneous aggregation into amyloid fibrils in solution, and on the nucleation and on the elongation steps of amyloid fibril formation. For this purpose, new chimeras containing 61, 67 and 73Q at position 197, or 55Q inserted at position 197 in between two different protease’s cleavage sites, that are relatively flexible, will be moreover created. Our results first demonstrate that the spontaneous aggregation into amyloid fibrils in solution is correlated to the polyQ length with an exponential growth function, and that the elongation rate is linearly correlated to the polyQ length, independently of the protein context (i.e., conformation of BlaP, and/or location of the polyQ tract, and/or polyQ peptides inserted or not within BlaP). However, the location of the polyQ tract inside BlaP, and/or its conformational state, and/or the flexibility of polyQ flanking sequences, and/or the origin of constraints applied to the polyQ tract drastically influence the ability of a polyQ tract to trigger the nucleation and/or the elongation step of amyloid fibrils (variation in the Q-threshold and in the absolute rate of both steps). Altogether, our results suggest that non-polyQ regions constitute an additional potential therapeutic target, more specific than drugs targeting the polyQ sequence, to interfere with the nucleation and/or the elongation of amyloid fibrils, associated to neurotoxicity. A possible drug could be constituted by a ligand specific to non-polyQ regions of disease-associated proteins, which further increases the constraints applied to the polyQ expansion to prevent the disease onset and/or progression.

The resulting framework contains eleven indicators which are the most acceptable set of indicators for all the stakeholders. It answers to European legislation and strategies for biodiversity. It is intended to improve sustainability in the quarries and to help managing biodiversity, to allow setting up of appropriate reporting systems. The aim is to maintain the biodiversity status of the gypsum quarries. It is a flexible framework adaptable given the local context of each gypsum quarry in order to prove if a No Net Loss has been reached at a quarry’s scale. [less ▲]

Epitaxy of metal oxides is of great interest since it provides a way to obtain desired novel properties for the applications such as electronics and energy. However, earlier epitaxy research's have been restricted because of the limited range of compositions and low-index of commercially available single crystal substrates. Consequently, novel epitaxy synthesis methods need to be developed in order to go beyond the present demands of of single crystal substrates in terms of phase, composition, size, orientation and symmetry. In this research work, we have developed a high-throughput synthesis process, called combinatorial substrate epitaxy (CSE), where an oxide film is grown epitaxially on a polycrystalline substrate. As a proof-of-concept, we firstly fabricated Ca3Co4O9 films on Al2O3 ceramics. Films have a good local epitaxial registry, and the Seebeck coefficient is about 170 µV/K at 300 K. High quality BiFeO3/La0.7Sr0.3MnO3 thin film heterostructures were secondly deposited on dense LaAlO3 ceramics prepared by spark plasma sintering. Piezoforce microscopy was used to confirm the local ferroelectric properties. Thirdly, we investigate the growth of of metastable monoclinic Dy2Ti2O7 epitaxial films on polycrystalline La2Ti2O7 substrates. We conclude that CSE approach opens the way towards unexpected electronic properties in oxide films. [less ▲]
