Objective The aim of our research was to assess the feasibility and efficacy of a treatment assisted by diacetylmorphine in Liège. This treatment is offered to persons dependent on heroin who pursue street heroin use despite existing treatments. Methods Data were collected in a pilot project of Treatment Assisted by Diacetylmorphine (TADAM), which took place in Liège from 2007 to 2013. The heart of this project is a randomised controlled trial comparing a diacetylmorphine treatment – limited to 12 months – with existing methadone treatments. A participant was responder if he/she showed improvement on the level of street heroin use, health or criminal involvement. Other researches (mainly based on interviews) were added in order to understand interactions between the trial and its actors: heroin users (included or not-included), neighbours of the DAM centre, the staff of the DAM centre and staff of other institutions who worked with our target group in Liège. Results With the help of the centres, partners of the trial, 74 participants (of the 200 planned) were included and randomised: 36 in the experimental group and 38 in the control group. These participants were dependent on heroin for 20 years on average and had already tried 9 treatments for their addiction(s). At the end of the trial, the number of responders in the experimental group was greater but not significantly than in the control group (p=0.35). However, participants in the experimental group showed greater improvement than in the control group, on the level of street heroin use (p=0.0011) and physical (p=0.043) or mental (p=0.035) health. During the follow-up study, three months after the end of the 12 months of treatment, street heroin use in the experimental group had significantly increased (p=0.0052) and the difference with the control group was no longer significant (p=0.55). Discussion Participants included in the trial were, as expected, persons severely dependent on street heroin, who could not find a solution to their addiction with the existing treatments. Participants in the experimental group decreased significantly their street heroin use. However, in our follow-up study, street heroin use increased significantly in the experimental group 3 months after the end of the diacetylmorphine treatment. In the foreign studies, diacetylmorphine treatment showed greater efficacy compared to methadone treatment for this target group and the improvement was sustained after the trial even when the treatment was stopped, but not when the end of treatment was forced against the will of the patient. Nevertheless, our research showed the feasibility of a diacetylmorphine treatment in Liège and its acceptance by the actors involved in the trial. Conclusion Diacetylmorphine treatment is feasible in Belgium. In foreign studies, it showed more efficacy than methadone treatment and benefits gained with this approach were maintained during years. But these benefits disappear when the end of treatment is forced, against the will of the patient. [less ▲]

Unreinforced masonry (URM) is traditionally used in North-Western Europe as load- bearing solution for low- to mid-rise buildings. These regions are characterised by a low- to-moderate seismicity. Hence, the earthquake action has to be considered in the structural design. An adequate consideration of the seismic action requires to properly understand how the URM structures behave under this speci c dynamic action and investigations are still needed in that eld. The in uence of openings and walls perpendicular to the seismic action are two main issues. Moreover, the seismic response of these structures is a ected by technical solutions developed to face the demand in terms of building physics performances. Even though, these solutions are not yet integrated in current standards. This thesis aims at improving the understanding of the seismic behaviour of URM struc- tures using a particular type of masonry bonding, for constructional e ciency purposes. Hollow clay blocks are assembled by thin-bed layered glue-mortar joints and a tongue-and- groove system for the head joints. The consequences of speci c details such as an opening, a perpendicular wall or soundproo ng rubber layers are also studied. Four experimental campaigns are presented. Fourteen URM sub-structures including speci c details are tested in static-cyclic and dynamic conditions. Details of the set-up, instrumentation layout and testing procedures are given. Processing of the data is then performed and conclusions are drawn. Regarding the shake table tests, a general rocking be- haviour strongly dependent on the length of the wall and the presence of rubber, is observed. Recommendations for the consideration of soundproo ng devices and for the openings are proposed. The contribution to the strength of perpendicular walls is also highlighted. Based on the dynamic characterisation of the specimens, equivalent mechanical properties are calibrated thanks to the frequency equation, derived from the Timoshenko beam theory. Two sets of boundary conditions are de ned to t the testing con gurations. The relevance of this theory is assessed and the importance of each term of the equation is discussed. In order to extend the results to complete buildings, the tested specimens are modelled in a software implementing an equivalent frame at the macro-scale. A multi-linear material law is calibrated based on a single specimen chosen as reference, in order to reproduce the experimental force-displacement curve. This law is then used for all specimens built in the same masonry type, independently of their geometry. A good approximation is obtained, even if the consideration of perpendicular walls could be improved. The shear capacity of non-rectangular URM walls depends on the compressive length. Its exact expression is thus developed with due consideration of the perpendicular section. Non linearities are observed due to the presence of the perpendicular section and simpli - cations are made for hand calculations. Both the use of the exact and simpli ed expressions in the assessment of the shear resistance provide results similar to the experiments. Finally, the modelling of the rocking motion is investigated. The walls without sound- proo ng devices are modelled following di erent existing models and their predictions are compared with experimental measurements, showing that masonry cannot be assumed as rigid. A main issue is the handling of the transition with impacts. A new model including two rigid blocks and exible and viscous layers is developed to reproduce the rocking behaviour of walls including rubber layers. In presence of rubber, the URM wall can be considered as rigid and model predictions satisfactorily corroborate the experimental measurements. [less ▲]

Alongside established, high-profile non-governmental organisations (NGOs), many individuals decide that they need to “do something” to improve the lives of the people they have met (while travelling, living in another country or adopting a child, etc.). These people join forces with a small group of friends to set up their own development organisations (referred to hereafter as “popular development initiatives”, or PDIs). At present, one of the major concerns in international development cooperation is to make development workers more professional in the interest of better aid effectiveness. This thesis therefore looks at the discourses and practices of these “ordinary” citizens, in order to highlight their role and to identify key issues for this sector. More specifically, we study the dialectic process by which NGO staff and PDI volunteers build and define their professional and amateur legitimacy as development actors, through the prism of the interactionist perspective of the sociology of professional groups. We also draw on the sociology of public action to consider how public authorities, through their policy tools, influence the responsibility and legitimacy of these actors, the interactions between them, and their mutual recognition. The need for professionalism also stems from demands by local partners in the developing world, so we have taken an interest in their perceptions in the case of Senegal. [less ▲]

À côté du contrat de travail, le droit du travail s'intéresse à d'autres relations contractuelles caractérisées par la subordination, que l'on nomme apprentissage et stage. Après avoir mis en avant la distinction entre le contrat de travail et les contrats relatifs à la formation préalable à l'embauche, la contribution propose un exposé synthétique des principaux types d'apprentissage et de stage. Elle se clôture par un relevé jurisprudentiel des éléments pertinents qui permettent de s'assurer que l'objet du contrat est la formation à un métier et non la réalisation d'un travail en contrepartie d'une rémunération.

Situer le récit d’anticipation dans l’histoire des pratiques culturelles, en particulier dans l’histoire littéraire, est une démarche problématique à plus d’un titre. L’une des résistances majeures est la tendance normative à réinterpréter les textes concernés en les classant soit dans les œuvres visionnaires géniales à sauver ponctuellement de l’oubli, soit dans les nombreuses prophéties non advenues ayant périmé à juste titre. Récit bref, roman ou essai fictionnel, le texte d’anticipation semble de la sorte condamné à cette réception binaire qu’il programme dans son pacte de lecture. Il s’emploie à traiter du futur alors même qu’il est étroitement lié à son premier contexte d’écriture par les réseaux éditoriaux, les supports médiatiques et les référents des représentations qui le composent. Cela contribue à le dater très fortement et à restreindre sa postérité à l’adéquation entre une visée prospective de la fiction et sa validation par l’Histoire. Le cas du récit d’anticipation invite ainsi à étudier la durée de vie de certaines productions culturelles au regard des constructions rétrospectives qui en sont faites : dans quelle mesure l’obsolescence contrainte d’un certain corpus littéraire peut-elle aider à penser la généricité dans l’histoire ? Les exemples choisis porteront sur un corpus francophone situé entre 1800 et 1950, période précédant l’émergence des collections françaises de science-fiction. On examinera spécifiquement les trois cas de figure suivants : les assises idéologiques du discours social (progrès, hygiénisme, saint-simonisme) chez Émile Souvestre (Le monde tel qu’il sera, 1846) ; l’anticipation mêlée à la satire journalistique dans l’œuvre d’Albert Robida et le tropisme du spectacle (théâtre, féérie, magie) dans l’esthétique du « merveilleux scientifique ».
