La mémoire du génocide des Juifs est très présente dans les sociétés occidentales à travers des vecteurs de socialisation comme l’école, les médias, la famille, et plus récemment les réseaux sociaux et Internet. Quelles peuvent être les conséquences de la transmission de cette mémoire sur le développement des attitudes et des comportements politiques des jeunes ? C’est la question centrale de l’ouvrage qui présente les connaissances, les émotions et les valeurs mobilisées par les jeunes dans le cadre de groupes de discussion, et qui surtout les met en perspective avec leurs représentations et leurs perceptions des autorités politiques. Au final, plusieurs questions difficiles pour le futur émergent. En effet, à bien des égards, l’impact de la transmission de la mémoire du génocide des Juifs sur la socialisation politique des jeunes pose la question de l’éventualité de sa répétition, de son caractère exceptionnel, de sa compréhension, ou encore de l’effacement de sa mémoire dans la dynamique des générations et du temps qui passe.

In a context of increasing demand for meat and fish, the animal production sector is seen as a driver of growth for agriculture in Hai Duong Province, Vietnam. However, the growth prospects of this sector seem undermined by a limited credit supply. This study aims to explore access to credit by animal producing households, factors affecting their credit accessibility and the influence of credit and non-credit factors on animal production. The study results show that all households surveyed, both the animal-based group and the non animal-based group, need credit for both production activities and consumption. The formal sector, which for the most part provides credit for production activities, did not meet the credit needs of the animal producers. Thus, only 52% of surveyed households applied to commercial banks for credit, the remaining households felt that they had no chance of receiving loans. Looking at the household characteristics as the center for analysis, it was found that physical collateral, the area of the fish pond and social relationships positively affected the probability of credit access by animal producing households. In addition, the area of the fish pond, number of laborers, share of income from animal production and social relationships positively affected the borrowing amount that was approved by commercial banks. Among animal producing households, the poor households likely had a lower probability of credit access and lower borrowing amounts than the non-poor households. The credit needs of farmers were often more rationed by commercial banks. Furthermore, some weaknesses of the rural lending apparatus in Hai Duong Province impeded access to credit by households. The credit constrained households accounted overall for 71% of the households surveyed. On the other hand, both the animal-based group and the animal-based group also suffered from some non-credit constraints relating to production and marketing. Within each group, the non-credit constraints caused a similar negative influence on animal production income, relatively speaking. Credit accessibility was different among households. As a result, for a given production unit, credit constrained households generated less income than non-credit constrained households. Improving the credit supply and some non-credit factors is expected to increase income from animal production. The study mainly suggests that the local authorities should support small-scale animal producers to establish animal producer groups to overcome constraints to credit access, production and marketing. Besides strengthening the credit supply to individual borrowers, the formal sector should grant feed purchase credit vouchers to animal producing groups. [less ▲]

In Vietnam, the vermicelli of Canna edulis Ker Gawl. (C. indica L.) is an artisanal and traditional product, regularly consumed in the festive occasions. From Canna edulis Ker Gawl cultivation to trading of vermicelli of Canna edulis at the local level, the vermicelli commodity chain belongs to peasant economy with many actors involved. This research aims at a better understanding of how the actors of vermicelli commodity chain adapt to current socio-economic and environmental conditions of the villages which belong to two communes (Tu Dan and Yen Phu) located in Hung Yen Province. The surveys among 90 farmers and discussions with a group of producers who cultivate the canna and practice flour processing, and a group of vermicelli processors have been carried out from 2010 to 2012. According to our research results, vermicelli commodity chain has created a considerable additional quantity of jobs for local people within the villages of vermicelli processing and the neighboring ones. Thanks to these activities, the rural households income and production investment have been increased. Net income estimated per hectare of canna is about 22.2 million VND (about 822 €), and nearly 4.5 million VND (167 €) per ton of flour produced, and up to 1.7 million VND per ton of vermicelli product (about 63 €). In addition, these activities allow to diversify the sources of family incomes in the countryside. These activities also contribute to stabilize and increase the living standard of farmers (in 2010, the net family income (NFI) due to canna production accounted for 8% to 34 % of farming income; the NFI of vermicelli processing represented between 35% and 86 % of total processing family income). The value-added generated from this vermicelli commodity chain is important, up to 186 million VND (about 7,900 €) per hectare of canna, in which 38 % for flour processing; 20% for vermicelli processing and 20 % for canna cultivators. Thus, the vermicelli commodity chain contributes to meet a specific demand for traditional food in Vietnam. This chain contributes to the rural economy of traditional villages through improving the sources of familial income. However, it is necessary to increase the product quality and to improve the vertical and horizontal linkages between the actors in order to guarantee the sustainable development of this vermicelli chain.

For several years, mesenchymal stem cells (MSC) have been evaluated in vivo and in vitro for their immunomodulatory, anti-inflammatory, anti- ischemia-reperfusion injury and “tissue repair” properties. These characteristics could make them interesting in various clinical applications, and particularly in organ transplantation. Taking advantage of our centre expertise and experience concerning MSC use in graft-versus-host disease after bone marrow transplantation and using already functioning GMP-compliant laboratory able to produce clinical-grade MSC, we initiated in 2011 a first trial exploring safety and tolerability of third party MSC infusions after kidney or liver transplantation in a prospective phase I-II study. In this study, after successful transplantation, 10 liver and 10 kidney transplant recipients under standard immunosuppressive treatment (tacrolimus, mycophenolate, steroids) receive an intravenous infusion of 1.5 - 3x106/kg of third-party MSC, on post-operative day 3+/-2. These patients are prospectively compared to the same number of liver and kidney transplant recipients who meet inclusion criteria but do not receive MSC infusion. Safety is assessed by recording side effects, including opportunistic infections and cancers. Immunosuppressive potential is evaluated by rejection episode rates, graft/patient survivals, immunohistology of 3-month (kidney) and 6-month (liver) graft biopsies, and in vitro evaluation of recipient immunity profile. In a second step, reduction (kidney) and progressive weaning (liver) of immunosuppression is attempted in recipients who received MSC. Inclusion of liver patients is now complete, and to date 3 kidney patients received MSC. Primary results will be presented, and complete 6-month liver results are expected for the end of 2014. The next step will be to assert the immunosuppressive potential of MSC after organ transplantation, and the opportunity to develop larger randomised, controlled, phase III trials. [less ▲]

Les réformes institutionnelles de 1988-1989 ont transféré aux Communautés les compétences en matière d’enseignement. Pour la Communauté française, cette responsabilisation a très vite rimé avec la nécessité de réaliser d’importantes économies et donc d’importantes réformes structurelles. Une première vague de protestation secoue Bruxelles et la Wallonie en 1990 mais, cinq ans plus tard, un nouveau plan d’économies préparé par la socialiste Laurette Onkelinx, Ministre-Présidente de la Communauté française, en charge notamment de l’Education, donne naissance à un long et douloureux mouvement de protestation. Celui-ci semble matérialiser la rupture entre une base enseignante proche, selon les réseaux, du PS ou du PSC, et un Exécutif au sein duquel ces deux partis fonctionnent en coalition. Réduction des dépenses, suppression de trois mille postes, fusions d’écoles, tous les ingrédients sont réunis pour que la situation soit explosive. Elle va l’être d’autant plus – et cela marquera d’ailleurs durablement les esprits – que certaines manifestations de mécontentement vont s’exprimer avec violence, s’attaquer à des symboliques fortes (la Fête de la Communauté française en septembre 1995, le 1er mai 1996) et perturber la vie privée de la Ministre et de son entourage. Notre contribution s’inscrit dans le volet « images produites ». Elle s’interrogera sur le rôle des images dans la représentation que la presse écrite généraliste a donnée du mouvement enseignant et des enseignants eux-mêmes durant ce conflit. Grâce à certaines archives numérisées, le traitement du mouvement par l’audiovisuel public pourra, lui aussi, être abordé. La photographie de presse, la caricature et le reportage ont-ils contribué à présenter le mouvement enseignant de manière objective et dépassionnée ? Ont-ils au contraire – et jusqu’à quel point ? - intégré les clichés traditionnels véhiculés sur cette catégorie socio-professionnelle (conservatisme, attachement à de supposés « privilèges »…). Quelle image est renvoyée du syndicalisme enseignant ? Comment est mise en scène la relation triangulaire entre grévistes, ministre et public de l’école (parents et élèves) ? Quels sont le poids et le rôle dévolus à chacun ? Quelle est, spécifiquement, le traitement réservé au mouvement par un journal comme La Wallonie ? Comment a-t-il accompagné en images la rupture entre le monde enseignant, la CGSP et le parti socialiste, culminant le 1er mai 1996 ? [less ▲]

Since 1998, Viet Nam developed many poverty reduction strategies with the assistance of the WB and the IMF. However, although the national rate of poverty decreased in absolute terms, it does not reflect a real reduction in poverty and does not take into account the nature of poverty. Income and opportunities inequality increased between urban and rural areas, between different social classes and between the Kinh (majority group in Viet Nam) and ethnic minorities. Poverty of ethnic minorities has become an ongoing challenge. In 2010, there were 66.3% of the poor among ethnic minorities against only 12.9% for the Kinh population. This thesis illustrates a reflection on the issue of poverty in Viet Nam and in particular mountainous northern regions where the poverty rate is the highest, reaching 39.4 % in 2012. The historical approach, the capacity approach, the descriptive statistical analysis and case analysis are used to conduct this research. The first difficulty is the identification of poor households and beneficiaries of poverty reduction strategies. Other difficulties are disclosed by the analysis of strategies against poverty: information confusion, budget limitation, insufficient participation of local people in program planning and monitoring, limited autonomy at the local level. Finally it appears that strategies against poverty are not efficient. In addition, land resource privatization, particularly forest resources, limits minority farmers’ ability to cope with unexpected risks Faced with this situation, a possible solution could be to strengthen the role of farmers' associations. Taking into account the ideas and initiatives of local actor, driven by farmers' associations, would have a positive impact on the poverty reduction strategy. Donations and subsidies to individuals should no longer be practiced. In the present threatening world, solidarity among small farmers is necessary to enable them to find their place in the production system and keep the justified profits. In the long run, it is better to give financial support to assist groups and support initiatives by associations of small farmers to facilitate their participation in the market economy while improving their well-being.

Since the end of 1990’s, there has been a growing interest to combat child labour in Burkina Faso. State actors as well as civil society organisations have started to engage themselves to urgently combat the worst forms of child labour. The 2006 National Statistical Survey found that 41.1 % of children aged 5 to 17 years were economically active. Compared to other West African countries, Burkina Faso is said to have the highest rate of children involved in hazardous work, which is one working child out of two. In this context of renewed interest regarding child labour, working children have their say. Based on a qualitative survey, this paper is focused on the perspectives of children working in two of the eleven hazardous sectors of activity identified by the 2009 National Decree: a stone quarry located in the capital Ouagadougou and an artisanal gold mine in a northern rural area. The paper aims to better understand the experience and opinions of children at work, to describe what work means to them, the role and the benefits of work in their lives and the difficulties they encounter. The focus is also on what children (and their families) think about public action against child labour and what are their aspirations regarding the current interventions. The analysis shows that if economic reasons lead children to work in in these two sectors of activity, this not the only determinant. The wish of a large number of children (and their parents) to find other less difficult work reopens the debate on children’s right to work. The results of this study reveal that there is a need to better understand how working children and their fmailies negotiate everyday life within the socio-cultural and economic context of Burkina Faso.

After the tragedy of the genocide against Tutsi in 1994, the Rwandan Government has developed and implemented different programmes and interventions in the sector of social protection in order to reduce the poverty of the vulnerable populations and so reach the Millennium Development Goals (MDGs). The different interventions done in the context of social security of the poor people are considered as means of increasing the economy, integrating people in employment market, improving human development thanks to a better access to health and education, and reducing poverty. After the context and justification of the research as well as the methods for data collection, this study focuses primarily on the conceptualization of resilience and connected concepts. Secondly, it scrutinizes the impact of the three programmes of social protection that were developed to reduce poverty of the beneficiaries. The first programme is FARG that supports the survivors of the 1994 genocide against the Tutsi in the domain of education, access to accommodation, medical health and income generating activities. The second programme is Ubudehe-VUP-2020. This one helps very poor households via direct financial transfers, creation of jobs and access to financial services. Girinka is the third programme; it contributes to food improvement, subsistence means and land fertility by supplying a dairy cow to poor families. In third position, this research assesses the achievements of the association of the widows survivors of genocide called - Agahozo (AVEGA) as well as the successes so far reached by the widows beneficiaries. The widows consider AVEGA as an important ‘tutor for resilience’ because it not only deals with their psychological aspects related to the tragedies they experienced but also the promotion and development of economic activities that can supply them with an income for their social reintegration at both economic and social levels. Thus, AVEGA involves a diversity of actors in order to help the widows and implement various income generating activities. Research conducted on the field has targeted, in last position, the most resilient widows. These widows have got support from social protection programmes and AVEGA, in order to involve in income generating activities among which the most developed are agriculture, animal rearing and commerce. All in all, the widows of genocide who were surveyed positively commented the support they get from SPP and AVEGA regarding the reinforcement of their economic resilience. [less ▲]

While 3D cinema is becoming increasingly established, little effort has focused on the general problem of producing a 3D sound scene spatially coherent with the visual content of a stereoscopic-3D (s-3D) movie. The perceptual relevance of such spatial audiovisual coherence is of significant interest. In this thesis, we investigate the possibility of adding spatially accurate sound rendering to regular s-3D cinema. Our goal is to provide a perceptually matched sound source at the position of every object producing sound in the visual scene. We examine and contribute to the understanding of the usefulness and the feasibility of this combination. By usefulness, we mean that the technology should positively contribute to the experience, and in particular to the storytelling. In order to carry out experiments proving the usefulness, it is necessary to have an appropriate s-3D movie and its corresponding 3D audio soundtrack. We first present the procedure followed to obtain this joint 3D video and audio content from an existing animated s-3D movie, problems encountered, and some of the solutions employed. Second, as s-3D cinema aims at providing the spectator with a strong impression of being part of the movie (sense of presence), we investigate the impact of the spatial rendering quality of the soundtrack on the reported sense of presence. The short 3D audiovisual content is presented with three different soundtracks. These soundtracks differ by their spatial rendering quality, from stereo (low spatial coherence) to Wave Field Synthesis (WFS, high spatial coherence). The original stereo version serves as a reference. Results show that the sound condition does not impact on the sense of presence of all participants. However, participants can be classified according to three different levels of presence sensitivity with the sound condition impacting only on the highest level (12 out of 33 participants). Within this group, the spatially coherent soundtrack provides a lower reported sense of presence than the other custom soundtrack. The analysis of the participants' heart rate variability (HRV) shows that the frequency-domain parameters correlate to the reported presence scores. By feasibility, we mean that a large portion of the spectators in the audience should benefit from this new technology. In this thesis, we explain why the combination of accurate sound positioning and stereoscopic-3D images can lead to an incongruence between the sound and the image for multiple spectators. Then, we adapt to s-3D viewing a method originally proposed for 2D images in the literature to reduce this error. Finally, a subjective experiment is carried out to prove the efficiency of the method. In this experiment, an angular error between an s-3D video and a spatially accurate sound reproduced through WFS is simulated. The psychometric curve is measured with the method of constant stimuli, and the threshold for bimodal integration is estimated. The impact of the presence of background noise is also investigated. A comparison is made between the case without any background noise and the case with an SNR of 4 dBA. Estimates of the thresholds and the slopes, as well as their confidence intervals, are obtained for each level of background noise. When background noise is present, the point of subjective equality (PSE) is higher (19.4° instead of 18.3°) and the slope is steeper (-0.077 instead of -0.062 per degree). Because of the overlap between the confidence intervals, however, it is not possible to statistically differentiate between the two levels of noise. The implications for the sound reproduction in a cinema theater are discussed. [less ▲]

We analyze the influence of dipole-dipole interactions between Rydberg atoms on the generation of Abelian artificial gauge potentials and fields. When two Rydberg atoms are driven by a uniform laser field, we show that the combined atom-atom and atom-field interactions give rise to nonuniform, artificial gauge potentials. We identify the mechanism responsible for the emergence of these gauge potentials. Analytical expressions for the latter indicate that the strongest artificial magnetic fields are reached in the regime intermediate between the dipole blockade regime and the regime in which the atoms are sufficiently far apart such that atom-light interaction dominates over atom-atom interactions. We discuss the differences and similarities of artificial gauge fields originating from resonant dipole-dipole and van der Waals interactions. We also give an estimation of experimentally attainable artificial magnetic fields resulting from this mechanism and we discuss their detection through the deflection of the atomic motion. [less ▲]
